(COVER PAGE CONTINUED)

         GST Equipment  Funding,  Inc., a Delaware  corporation ("GST Funding"),
hereby  offers,  upon the terms and subject to the  conditions set forth in this
Prospectus and the accompanying Letter of Transmittal (the "Exchange Offer"), to
exchange $1,000  principal  amount of its 13 1/4% Senior Secured  Exchange Notes
Due 2007 (the "New Notes") for each $1,000  principal  amount of its outstanding
13 1/4% Senior  Secured Notes Due 2007 (the "Old Notes").  The offer and sale of
the New Notes have been registered  under the Securities Act of 1933, as amended
(the  "Securities  Act"),  pursuant to the  Registration  Statement  (as defined
herein)  of which  this  Prospectus  constitutes  a part.  As of June 30,  1997,
$265,000,000  aggregate  principal amount of the Old Notes was outstanding.  The
Exchange  Offer is being made pursuant to the terms of the  registration  rights
agreement (the "Registration Rights Agreement") dated May 13, 1997, by and among
GST Funding,  GST USA, Inc. ("GST USA"), GST  Telecommunications,  Inc. ("GST"),
and Morgan Stanley & Co.  Incorporated  ("Morgan  Stanley"),  Dillon, Read & Co.
Inc. ("Dillon Read") and TD Securities (USA) Inc. ("TD Securities," and together
with Morgan  Stanley  and Dillon  Read,  the  "Placement  Agents") as  Placement
Agents,  pursuant to the terms of the Placement  Agreement dated May 8, 1997, by
and among GST Funding,  GST USA, GST and the Placement Agents. The New Notes and
the Old Notes are  collectively  referred  to  herein  as the  "Notes."  As used
herein, the term "Holder" means a holder of the Notes.

         THE NOTES ARE SENIOR,  SECURED OBLIGATIONS OF GST FUNDING,  AND WILL BE
UNCONDITIONALLY AND IRREVOCABLY ASSUMED BY GST USA AND GUARANTEED BY GST, ON MAY
13,  2000,  OR  EARLIER  IF  PERMITTED  UNDER  THE  TERMS OF GST USA'S AND GST'S
OUTSTANDING  INDEBTEDNESS.  Neither  GST USA nor GST will be liable on the Notes
until they are assumed by GST USA. There is a substantial  risk that GST USA may
be unable to assume the Notes by May 13,  2000.  See "Risk  Factors --  Possible
Inability of GST USA to Assume,  GST to Guarantee  and GST Funding to Redeem the
Notes."

         Once the Notes  are  assumed  by GST USA,  the  Notes  will be  senior,
secured  indebtedness of GST USA and GST USA's  obligations under the Notes will
be fully and unconditionally  guaranteed on an unsubordinated  basis by GST (the
"Note Guarantee").  The Note Guarantee will be senior, unsecured indebtedness of
GST. At June 30, 1997, GST Funding had no outstanding  borrowings other than the
Notes. GST Funding is a wholly-owned,  special purpose finance subsidiary of GST
USA, and GST USA and GST are each holding  companies.  GST USA is a wholly-owned
subsidiary of GST that owns,  directly or  indirectly,  the capital stock of all
but three of the Company's  operating  subsidiaries.  See "Business -- Corporate
Organization"

         GST  Funding  will accept for  exchange  any and all Old Notes that are
validly tendered and not withdrawn on or prior to 5:00 p.m., New York City time,
on the date the Exchange  Offer  expires,  which will be __________ __, 1997 [20
BUSINESS DAYS AFTER  COMMENCEMENT  OF THE EXCHANGE  OFFER],  unless the Exchange
Offer is extended (the "Expiration Date"). Tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration  Date. The
Exchange Offer is not conditioned upon any aggregate minimum principal amount of
Old Notes being tendered for exchange. However, the Exchange Offer is subject to
certain  conditions,  which may be waived by GST  Funding,  and to the terms and
provisions of the Registration Rights Agreement.  Old Notes may be tendered only
in  denominations of $1,000  aggregate  principal amount and integral  multiples
thereof.  GST Funding has agreed to pay the expenses of the Exchange Offer.  See
"The Exchange Offer."

         Any waiver,  extension or  termination  of the  Exchange  Offer will be
publicly  announced  by GST  Funding  through  a release  to the Dow Jones  News
Service and as otherwise required by applicable law or regulations.

         The Notes were issued in a private placement (the "May Offering") under
an  indenture  (the  "Indenture"),  dated as of May 13,  1997,  by and among GST
Funding,  GST,  GST USA and  United  States  Trust  Company of New York (in such
capacity,  the  "Trustee").  The New Notes will be  obligations  of GST  Funding
(until  they are  assumed by GST USA) and are  entitled  to the  benefits of the
Indenture.  The  Indenture  provides  that GST  Funding  must use all of the net
proceeds  of the May  Offering  (in  addition  to any cash on hand)  not used to
refinance intercompany indebtedness on the closing date of the May Offering (the
"Closing  Date") to purchase United States  government  securities (the "Pledged
Securities")  and must  pledge the  Pledged  Securities  to the  Trustee for the
benefit of the

<PAGE>

Holders.  In addition,  in  consideration  for GST Funding  making the financing
through the May Offering  available to GST USA and for GST Funding  facilitating
the  purchase  of GST  USA's  equipment,  GST USA has  agreed to pay any fees or
expenses incurred by GST Funding in connection therewith, and in support of such
obligations  GST USA has issued to GST Funding a promissory  note  guaranteed by
GST (the "Initial  Note").  The Notes are secured by a first  priority  security
interest in the Pledged Securities and in the accounts  established  therefor by
the Trustee (the "Pledge  Account") and by a first priority security interest in
the Initial Note. Upon written request from GST Funding to the Trustee,  Pledged
Securities  (other than Interest  Collateral (as  hereinafter  defined)) will be
released  from the Pledge  Account to GST  Funding in order to finance  the cost
(including,  without limitation, the cost of design, development,  construction,
acquisition,  installation or integration)  (collectively,  "Acquired  Equipment
Cost") of  telecommunications  inventory or equipment purchased or leased by GST
Funding ("Acquired Equipment"). As of June 30, 1997, the proceeds of sale of the
Old Notes have been used to purchase  $204.8  million of Pledged  Securities and
$35 million was  outstanding  under the Initial Note. At that date,  GST Funding
had  refinanced  approximately  $41.5 million of  intercompany  indebtedness  in
respect of Acquired Equipment from such proceeds.  The Notes are also secured by
a first priority security interest in all Acquired Equipment held by GST Funding
and,  upon the  sale of  Acquired  Equipment  to GST USA or the  refinancing  of
Acquired Equipment  indebtedness,  all secured  intercompany notes issued by GST
USA and guaranteed by GST (the "Intercompany  Notes"),  which will be secured by
Acquired Equipment.

         The form and  terms of the New  Notes  are  identical  in all  material
respects to the form and terms of the Old Notes,  except that the offer and sale
of the New Notes have been  registered  under the Securities  Act. Any Old Notes
not tendered and accepted in the Exchange Offer will remain outstanding and will
be  entitled  to all the  rights  and  preferences  and will be  subject  to the
limitations  applicable thereto under the Indenture.  Following  consummation of
the Exchange Offer,  the Holders of Old Notes will continue to be subject to the
existing restrictions upon transfer thereof and GST Funding will have no further
obligation to such Holders to provide for the registration  under the Securities
Act of the  offer  and  sale  of the  Old  Notes  held by  them.  Following  the
completion  of the  Exchange  Offer,  none of the Notes will be  entitled to the
contingent  increase  in interest  rate  provided  pursuant to the  Registration
Rights Agreement. See "The Exchange Offer."

         The Notes will  mature on May 13,  2007.  Interest on the Notes will be
paid in  cash at a rate of 13 1/4%  per  annum  on each  May 1 and  November  1,
commencing November 1, 1997.

         The Notes will be  redeemable  at the option of GST USA, in whole or in
part,  at any time or from time to time,  on or after May 1, 2002,  initially at
106.625% of their principal amount, plus accrued and unpaid interest,  declining
ratably to 100% of their principal  amount,  plus accrued and unpaid interest on
or  after  May 1,  2004.  If on May  13,  2000  GST  USA  is  prohibited  by its
outstanding  indebtedness  from  assuming  all of the Notes,  GST  Funding  will
redeem,  upon not less than 10 nor more than 30 days' notice, the portion of the
Notes that cannot be assumed, at 101% of their principal amount plus accrued and
unpaid interest to the date of redemption. In addition, upon a Change of Control
(as  hereinafter  defined),  GST Funding or GST USA, as the case may be, will be
required  to make an offer to  purchase  the Notes at a purchase  price equal to
101% of their principal amount plus accrued  interest.  See "Description the New
Notes -- Mandatory  Redemption," "-- Optional Redemption," and "-- Repurchase of
Notes Upon Change of Control."

   
         Based on no-action  letters  issued by the staff of the  Securities and
Exchange  Commission (the  "Commission") to Exxon Capital  Holdings  Corporation
(available May 13, 1988), Morgan Stanley & Co.  Incorporated  (available June 5,
1991) and Shearman & Sterling  (available  July 2, 1993),  GST Funding  believes
that New Notes issued  pursuant to this Exchange Offer in exchange for Old Notes
may be offered for resale,  resold and otherwise transferred by a Holder thereof
other than (i) a  broker-dealer  who purchased  such Old Notes directly from GST
Funding to resell pursuant to Rule 144A or any other  available  exemption under
the Securities  Act or (ii) a person that is an "affiliate"  (within the meaning
of Rule  405 of the  Securities  Act) of GST  Funding,  GST USA or GST,  without
compliance  with the  registration  and  prospectus  delivery  provisions of the
Securities  Act,  provided  that the  Holder is  acquiring  the New Notes in the
ordinary course of its business and is not participating, and has no arrangement
or understanding with any person to participate,  in the distribution of the New
Notes.  Holders of Old Notes who tender in the Exchange Offer with the intention
to participate in a distribution of the New Notes may not rely upon the position
of the staff of the  Commission  enunciated  in the  above-referenced  no-action
letters, and, in the absence of an exemption,  must comply with the registration
and prospectus delivery requirements of the
    


<PAGE>

Securities Act in connection with a secondary resale transaction. Holders of Old
Notes wishing to participate in the Exchange Offer must represent to GST Funding
in the Letter of Transmittal that such conditions have been met.

   
         Each broker-dealer (other than an "affiliate" of GST Funding, GST USA
or GST) that receives New Notes for its own account pursuant to the Exchange
Offer must acknowledge that it will deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of such New
Notes. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. This Prospectus, as
it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of New Notes received in exchange for
Old Notes where such Old Notes were acquired by such broker-dealer as a result
of market-making activities or other trading activities. GST Funding has agreed
that, for a period of 180 days after the consummation of the Exchange Offer, it
will make this Prospectus available to any broker-dealer for use in connection
with any such resale. See "Plan of Distribution." Any broker-dealer who is an
affiliate of GST Funding, GST or GST USA may not rely on such no-action letters
and must comply with the registration and prospectus delivery requirements of
the Securities Act in connection with a secondary resale transaction.
    

         The New Notes  constitute a new issue of securities with no established
trading  market.  GST Funding is seeking to list the Old Notes on the Luxembourg
Stock Exchange.  GST Funding does not intend to list the New Notes on any United
States  securities  exchange  or to seek  approval  for  quotation  through  any
automated quotation system. GST Funding has been advised by the Placement Agents
that,  following completion of the Exchange Offer, they currently intend to make
a market in the New Notes; however, the Placement Agents are not obligated to do
so and  any  market-making  activities  with  respect  to the New  Notes  may be
discontinued at any time. The Placement  Agents may act as principal or agent in
such  transactions.  There can be no assurance that an active trading market for
the New Notes  will  develop.  To the  extent  that Old Notes are  tendered  and
accepted in the Exchange Offer, a Holder's  ability to sell untendered Old Notes
could be adversely affected.

         This Prospectus, together with the Letter of Transmittal, is being sent
to all registered Holders of Old Notes as of _____________ __, 1997.

         GST Funding will not receive any proceeds from this Exchange  Offer. No
dealer-manager is being used in connection with this Exchange Offer. See "Use of
Proceeds" and "Plan of Distribution."

         No person has been  authorized to give any  information  or to make any
representations in connection with the Exchange Offer other than those contained
in this  Prospectus  and the Letter of Transmittal  and, if given or made,  such
information or representation  must not be relied upon as having been authorized
by GST Funding,  GST USA, GST or the Exchange  Agent (as defined  herein).  This
Prospectus does not constitute an offer to sell or a solicitation of an offer to
buy the New Notes in any  jurisdiction  to any person to whom it is  unlawful to
make such offer or  solicitation  in such  jurisdiction.  The  delivery  of this
Prospectus shall not, under any  circumstances,  create any implication that the
information herein is correct at any time subsequent to its date.

                                   THE COMPANY

         The  Company  provides a broad range of  integrated  telecommunications
products and services, primarily to customers located in the western continental
United States and Hawaii. As a competitive local exchange carrier ("CLEC"),  the
Company  operates  state-of-the-art,  digital  telecommunications  networks that
provide an  alternative  to incumbent  local exchange  carriers  ("ILECs").  The
Company  provides,  through its established  sales channels,  telecommunications
services that include long distance, Internet and data transmission services and
recently introduced local dial tone services. The Company also produces advanced
telecommunications switching platforms with integrated applications software and
network  telemanagement  capabilities  through its  equipment  subsidiary,  NACT
Telecommunications, Inc. ("NACT").

   
         The  Company's  digital  networks  currently  serve  cities in Arizona,
California,  Hawaii, New Mexico, Texas and Washington.  In addition, the Company
has networks under construction which, when completed,  will expand its regional
footprint to Oregon.  Management believes that the Company has an opportunity to
leverage  its  network   infrastructure  and  service  capabilities  to  provide
customers with a complete solution to their telecommunications requirements. The
Telecommunications  Act  of  1996  (the  "Telecommunications   Act")  and  state
regulatory   initiatives  have  substantially  changed  the   telecommunications
regulatory  environment  in the United States.  As a result of these  regulatory
changes,  the Company is permitted in certain  states to provide local dial tone
in addition to its existing  telecommunications  service offerings.  In order to
capitalize on these  opportunities,  the Company has accelerated the development
of  additional  networks  within its region while  significantly  expanding  its
product and service offerings,  primarily with respect to the provision of local
services.

         GST USA is a wholly-owned subsidiary of the Company that owns, directly
or  indirectly,  the capital stock of all but three of the  Company's  operating
subsidiaries. GST Funding is a wholly-owned,  special purpose finance subsidiary
of the Company, formed to issue the Old Notes and to purchase equipment with the
proceeds of the May Offering. GST Funding acts as a purchasing agent for GST USA
and sells to GST USA the equipment it purchases.  Ultimately,  such equipment is
leased to the operating subsidiaries of the Company by GST USA. See "Business --
Corporate Organization."
    

TELECOMMUNICATIONS NETWORK STRATEGY

         The Company's network strategy is to continue to develop and expand its
network  infrastructure to ultimately  assemble,  through a combination of owned
and leased facilities and joint ventures, an integrated regional network for the
on-net  provision of CLEC services  including  local,  long  distance,  Internet
access and data  services.  The  Company  will  continue to focus on the western
United  States  in order to take  advantage  of its  strategically  advantageous
position in California and Hawaii and the substantial telecommunications traffic
that exists among the western United States, Mexico, the Pacific Rim and western
Canada.

TELECOMMUNICATIONS SERVICES STRATEGY

         In conjunction with its network expansion,  the Company has developed a
strategy to leverage its existing  infrastructure,  customer base and experience
by providing a broad range of integrated telecommunications services to meet the
voice and data  needs of its  end-user  customers.  The  Company's  sales  force
primarily  focuses on business,  government  and academic  end-users  within its
region  that have  significant  telecommunications  requirements.  To meet these
customers'  needs,  the Company offers a number of  telecommunications  services
including:

         LOCAL  SERVICES.  The Company  plans to  continue to install  switching
equipment  in its  operational  networks,  in markets  where it is  constructing
networks  and in  certain  other  cities  where  the  Company  will rely on ILEC
facilities for transmission,  as demand warrants.  Once a switch is operational,
where  regulatory  conditions  permit,  the Company  intends to offer local dial
tone,  in addition to enhanced  services such as ISDN,  Centrex,  voice mail and
other custom calling features.

         LONG  DISTANCE  SERVICES.  The Company  offers basic and enhanced  long
distance  services,  such as toll free,  calling card,  prepaid calling card and
international  call  back  services,   targeting  primarily  business  customers
purchasing  between  $200 and $15,000 of services per month as well as resellers
and other carriers. The Company has recently expanded its long distance products
and services  through the  acquisition of Action Telcom Co.  ("Action  Telcom"),
Call  America  Business  Communications  Corp.  (subsequently  renamed  GST Call
America)  and  certain  of its  affiliated  companies  (collectively,  "GST Call
America"),  TotalNet  Communications  Inc.  ("TotalNet")  and  the  business  of
Texas-Ohio   Communications,   Inc.  and  affiliated  companies   (collectively,
"Texas-Ohio"). These acquisitions provide additional sales distribution channels
in areas in and around the Company's existing and planned networks.  The Company
intends to continue to pursue acquisitions of long distance carriers.

         INTERNET SERVICES.  In March 1996, the Company acquired the business of
Reservations, Inc. d/b/a Hawaii On Line ("Hawaii On Line"), the largest Internet
access  provider in Hawaii.  The Company is also  presently  providing  Internet
services to  customers in Portland and  Vancouver  (Washington).  In addition to
providing  Internet  access,  the  Company  presently  offers   Internet-related
services such as World Wide Web ("Web") site  development and hosting,  provides
electronic data interchange ("EDI") services and is in the process of developing
various Internet software applications.  Management believes that these services
will become an important  component of the Company's  overall product  offerings
and intends to continue to expand its  Internet  access and service  business to
other markets.

         DATA SERVICES.  The Company  offers  national and  international  frame
relay  services  on its own frame relay  network and through an  interconnection
agreement  with  Intermedia  Communications  Inc.  ("Intermedia").   Under  this
agreement,  the Company and  Intermedia  have agreed to link their data networks
and  terminate  one another's  traffic.  The Company  plans to offer  additional
services  including   asynchronous   transfer  mode  ("ATM"),   high  speed  LAN
connectivity,  video  conferencing,  multimedia  networking and other  bandwidth
intensive applications.

         The  Company is  expanding  its  telecommunications  services  business
through  internal  development  and will continue to explore  opportunities  for
further expansion by acquisitions and joint ventures.

MANUFACTURING

         The Company, through its equipment subsidiary,  NACT, produces advanced
telecommunications switching platforms with integrated applications software and
network  telemanagement  capabilities.  NACT's  customers  include long distance
carriers,  prepaid debit (calling) card and prepaid cellular network  operators,
international    callback/reorigination    providers    and   other    specialty
telecommunications  service providers.  NACT's products and services include the
recently  introduced STX  application  switching  platform (the "STX"),  the NTS
telemanagement  and  billing  system  (the  "NTS")  and  facilities   management
services. In March 1997, NACT completed an initial public offering of its common
stock (the "NACT  Offering"),  pursuant  to which the  Company and NACT sold one
million and two million shares, respectively,  of NACT's common stock, resulting
in gross  proceeds  to the  Company  and NACT of $10  million  and $20  million,
respectively.  As a result of the NACT Offering,  the Company's interest in NACT
has been reduced to approximately 63%.

FINANCING PLAN

   
         The  Company  has   historically   funded  its  capital   expenditures,
acquisitions,  working capital requirements and operating losses from public and
private  offerings of its Common Shares,  notes and warrants to purchase  Common
Shares and from funds made available  under  agreements  (the "Tomen  Facility")
with Tomen America,  Inc. ("Tomen  America"),  a subsidiary of Tomen Corporation
(and   together  with  Tomen  America  and  their   affiliates,   "Tomen"),   an
international  trading company.  Under the Tomen Facility,  Tomen agreed to make
available up to a total of $100.0 million of financing,  on a project-by-project
basis, for the construction and development of networks. At June 30, 1997, Tomen
had  provided or agreed to provide the Company  with $34.5  million of financing
under the Tomen  Facility and Tomen had  purchased  1,449,074  Common Shares and
warrants to purchase 171,155  additional  Common Shares.  On September 30, 1997,
Tomen provided the Company with an additional  $40.5 million of financing  under
the Tomen Facility for the Hawaiian  inter-island  submarine network and various
terrestrial  installations  and in  connection  with  such  financing  purchased
additional   Common  Shares  and  warrants  to  purchase   Common  Shares.   See
"Description of Certain  Indebtedness  and Redeemable  Preferred Shares -- Tomen
Facility."
    

         In December 1995, the Company sold units consisting in the aggregate of
$312.4 million principal amount at maturity of 13 7/8% Senior Discount Notes due
2005 of GST USA  (the  "Senior  Notes")  guaranteed  by GST  and  $39.1  million
principal amount at maturity of 13 7/8% Convertible Senior Subordinated Discount
Notes due 2005 of GST (the  "Convertible  Notes" and,  together  with the Senior
Notes,  the "1995 Notes")  guaranteed by GST USA,  receiving  gross  proceeds of
approximately  $180.0 million (the "1995 Notes  Offering").  See "Description of
Certain  Indebtedness  and  Redeemable  Preferred  Shares  --  Senior  Notes and
Convertible Notes."

         In September 1996, the Company entered into a Switching  Products Sales
Agreement  (the  "Siemens  Sales  Agreement")  with  Siemens   Stromberg-Carlson
("Siemens"),  pursuant to which the Company may purchase  switching  and related
equipment and software  from  Siemens.  The Company also entered into a Loan and
Security Agreement with Siemens (the "Siemens Loan Agreement") that provides for
up to an aggregate of $226.0 million of loans to finance the purchase of Siemens
equipment and certain equipment from other suppliers, of which $116.0 million is
presently available to the Company.  The Company may seek to increase the amount
available up to $226.0 million on an as-needed basis, subject to the negotiation
and  execution  of mutually  satisfactory  documentation.  In August  1996,  the
Company entered into a Network Products Purchase Agreement (the "Nortel Purchase
Agreement") with Northern Telecom Inc. ("Nortel"), pursuant to which the Company
has agreed to purchase switching and related equipment and software from Nortel.
In December  1996, the Company  entered into a $50.0 million  equipment loan and
security  agreement (the "NTFC Loan  Agreement")  with NTFC Capital  Corporation
("NTFC")  to  finance  the  purchase  of  Nortel  equipment  and  products.  See
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations  -- Liquidity  and Capital  Resources"  and  "Description  of Certain
Indebtedness and Redeemable Preferred Shares -- Equipment Financing."

         In October 1996, the Company completed a private placement of 2,000,000
special  warrants  (the "Special  Warrants") at a purchase  price of $11.125 per
Special  Warrant (the  "Special  Warrant  Offering").  Each  Special  Warrant is
exercisable for one Common Share and one-half of one underlying warrant (each an
"Underlying  Warrant"),  and all of such Special  Warrants have been  exercised.
Each Underlying  Warrant  entitles the holder to purchase one additional  Common
Share for a purchase price of $13.00 for one year from the date of issuance. See
"Management's  Discussion  and Analysis of Financial  Conditions  and Results of
Operations -- Liquidity and Capital Resources."

         In February  1997,  the Company  consummated a private  placement  (the
"Princes Gate  Investment") of $50.0 million of Series A Preference  Shares (the
"Redeemable  Preferred  Shares") with an affiliate of Princes Gate Investors II,
L.P. ("Princes Gate").  Princes Gate is a limited  partnership  consisting of an
affiliate  of Morgan  Stanley  and certain  private  investors.  The  Redeemable
Preferred  Shares,  which are  convertible  into Common Shares at any time after
February 28, 2000 at an imputed  conversion  price of $11.375 per Common  Share,
will not pay  dividends,  except to the extent cash dividends are paid on Common
Shares.  In addition,  the liquidation  and redemption  prices of the Redeemable
Preferred  Shares will accrete at a semi-annual rate of 11 7/8%. On February 28,
2004 and under certain circumstances,  the Redeemable Preferred Shares will also
be subject to mandatory  conversion or  redemption,  provided that to the extent
the Company is prohibited from paying the redemption  price in cash,  holders of
Redeemable  Preferred Shares may elect to convert such shares into Common Shares
and if such election is not

                                       -6-

<PAGE>

made, the Company may extend the mandatory  redemption  date to August 28, 2007.
See  "Description of Certain  Indebtedness  and Redeemable  Preferred  Shares --
Redeemable Preferred Shares."

   
         The Company anticipates making substantial capital  expenditures in the
future.  The majority of these  expenditures  is expected to be made for network
construction  and the purchase of switches and related  equipment to  facilitate
the  offering  of the  Company's  services.  The Company  believes  that the net
proceeds of the May Offering,  the Special Warrant  Offering,  the NACT Offering
and the Princes Gate Investment, other securities offerings, if any, consummated
in the  future,  together  with  cash  on hand  and  borrowings  expected  to be
available  under the Tomen  Facility and the equipment  financing  arranged with
Siemens and NTFC,  will provide  sufficient  funds for the Company to expand its
business as presently  planned and to fund its operating  expenses  through June
1998.  Thereafter,  the Company  expects to require  additional  financing.  The
extent  of  additional  financing  required  will  depend  upon  the rate of the
Company's expansion and the success of the Company's businesses. There can be no
assurance  that  additional  financing  will be  available to the Company or, if
available, that it can be obtained on acceptable terms or within the limitations
contained in the Tomen Facility,  the indentures under which the 1995 Notes were
issued (the "1995  Indentures"),  existing equipment financing  facilities,  the
indenture  under  which the Notes  are to be issued or in any  future  financing
arrangements.  See "Risk Factors -- Significant  Capital  Requirements," "Use of
Proceeds," and "Management's  Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."
    

RECENT DEVELOPMENTS

         In May 1997, GST Funding sold $265,000,000 of the Old Notes pursuant to
the Indenture in the May Offering.  Of the net proceeds of the May Offering,  as
of June 30,  1997  approximately  $93.8  million  was used to  purchase  Pledged
Securities  to fund the first six  scheduled  interest  payments  on the  Notes,
approximately  $54.3  million was used to  purchase  Acquired  Equipment  ($41.5
million  of which  was used to  refinance  intercompany  indebtedness),  and the
balance  will be used to finance  the  purchase  and  installation  of  Acquired
Equipment such as fiber optic cable,  switches and other related equipment.  See
"Description of the New Notes."

         Effective May 31, 1997, the Company  acquired Action Telcom by means of
a merger (the "Action Telcom Merger"), whereby Action Telcom was merged with and
into GST Action Telecom, Inc. ("GST Action Telecom"), a wholly-owned  subsidiary
of the  Company.  On the date of the  closing of the Action  Telcom  Merger (the
"Action Telcom Closing Date"), the Company delivered to the former  shareholders
of Action Telcom (the "Action Telcom  Shareholders") (i) an aggregate of 903,000
Common  Shares,  (ii)  $1,290,000  in cash  and  (iii)  promissory  notes in the
aggregate principal amount of $2,580,000, bearing interest at a rate of 8.5% per
annum,  payable as to one-half of the aggregate principal amount thereof on each
of the first  and  second  anniversaries  of the  Action  Telcom  Closing  Date.
Additional  Common  Shares will be issued to the Action Telcom  Shareholders  on
each of the first and second  anniversaries of the Action Telcom Closing Date if
the average  closing sale price of a Common Share on the AMEX (or the  Company's
then  principal  trading  market) does not exceed $10.00 for the 10  consecutive
trading days ending three  trading days prior to each such  anniversary.  Action
Telcom is a  facilities-based  telecommunications  company  located in  Abilene,
Texas that operates its own network and  switching  equipment,  originating  and
terminating its own traffic principally in Texas.

   
         On September 30, 1997, Tomen provided the Company with $40.5 million of
debt financing for the Company's  Hawaiian  inter-island  submarine  network and
various other  terrestrial  installations.  The fully  operational  inter-island
submarine network is the first to connect six of the major Hawaiian islands. The
terrestrial installations, which are in progress, include a fiber optic backbone
across the island of Hawaii,  a cable  plant on Maui and three fiber optic rings
on Ohau. In connection  with such  financing,  the Company entered into a credit
agreement with Tomen containing  substantially similar terms as those previously
entered into under the Tomen Facility,  except that the loan will amortize in 22
quarterly installments beginning two and one half years after the date financing
was provided.

         On  September  30,  1997,  the Company  announced  that it had retained
Hambrecht & Quist LLC to explore alternatives for monetizing its 63% interest in
NACT,  including a potential sale of some or all of its shares of NACT's capital
stock  to one or  more  strategic  investors.  Management  of  the  Company  has
determined  to focus its capital  resources  and  attention on its CLEC services
business.  The Company also  indicated its intention to invest the proceeds from

Resale   ...................................Based  on an  interpretation  by the
                                            staff of the Commission set forth in
                                            no-action  letters  issued  to third

                                            such Holder's business and that such
                                            Holder   has   no   arrangement   or
                                            understanding  with  any  person  to

Mandatory Redemption
  and Change of Control.....................If  on  May  13,  2000  GST  USA  is
                                            prohibited  by the  1995  Indentures
                                            from assuming all of the Notes,  GST
                                            Funding will  redeem,  upon not less
                                            than  10  nor  more  than  30  days'
                                            notice,  the  portion  of the  Notes
                                            that cannot be  assumed,  at 101% of
                                            their principal  amount plus accrued
                                            and unpaid  interest  to the date of
                                            redemption.

                                            Upon  a  Change  of   Control,   GST
                                            Funding or GST USA,  as the case may
                                            be,  will  be  required  to  make an
                                            offer  to  purchase  the  Notes at a
                                            purchase  price  equal  to  101%  of
                                            their principal  amount plus accrued
                                            interest.  See  "Description  of the
                                            New Notes --  Mandatory  Repurchase"
                                            and "--  Repurchase  of  Notes  Upon
                                            Change of Control."

                                            In the event that the New Notes were
                                            required  to be  redeemed  due  to a
                                            mandatory  redemption or repurchased
                                            due to a Change of  Control  and GST
                                            Funding  were  unable  to  redeem or
                                            repurchase  the  New  Notes,  as the
                                            case may be, the  result  would be a
                                            default  under the  Indenture.  Such
                                            default      would     result     in
                                            cross-defaults    under   the   1995
                                            Indentures,  the Tomen Facility, the
                                            Siemens Loan  Agreement and the NTFC
                                            Loan Agreement and the  indebtedness
                                            thereunder would be accelerated.  As
                                            of June  30,  1997,  $221.1  million
                                            accreted  value  of 1995  Notes  was
                                            outstanding   and  the  Company  had
                                            incurred     $32.3     million    of
                                            outstanding  indebtedness  under the
                                            Tomen  Facility,   $4.5  million  of
                                            indebtedness  under the Siemens Loan
                                            Agreement   and  $44.6   million  of
                                            outstanding  indebtedness  under the
                                            NTFC  Loan  Agreement.   If  such  a
                                            default  were to occur  prior to the
                                            time  GST  USA   becomes   a  direct
                                            obligor on the New  Notes,  the sole
                                            obligor   thereunder  would  be  GST
                                            Funding,  which  will have no assets
                                            other than the  collateral  securing
                                            the Notes.  Upon foreclosure after a
                                            default   upon   the   Notes,   such
                                            collateral  may not be sufficient to
                                            repay all  amounts due on the Notes.
                                            If  such a  default  were  to  occur
                                            after  the time GST USA  becomes  an
                                            obligor on the Notes,  such  default
                                            would    permit   the   holders   of
                                            substantially  all of the  Company's
                                            indebtedness   to   accelerate   the
                                            maturity thereof.

Conditional Guarantee.......................If  and  when  the  New   Notes  are
                                            assumed   by  GST  USA,   GST  USA's
                                            obligations under the New Notes will
                                            be   fully    and    unconditionally
                                            guaranteed   on  an   unsubordinated
                                            basis  by  GST.  However,  the  Note
                                            Guarantee  shall not be  enforceable
                                            against  GST in an  amount in excess
                                            of the net  worth of GST at the time
                                            that determination of such net worth
                                            is, under  applicable law,  relevant
                                            to the  enforceability  of such Note
                                            Guarantee.   Such  net  worth  shall
                                            include any claim of GST against GST
                                            USA for  reimbursement and any claim
                                            against  any  other   guarantor  for
                                            contribution.

Additional Amounts..........................Any   payments  in  respect  of  the
                                            Initial   Note,   the   Intercompany
                                            Notes,  or  after  May 13,  2000 the
                                            Notes,  made  by GST  will  be  made
                                            without withholding or deduction for
                                            Canadian taxes except as required by
                                            law   or   the   interpretation   or
                                            administration   thereof,  in  which
                                            case GST  will  pay such  additional
                                            amounts as may be  necessary so that
                                            the  net  amount   received  by  GST
                                            Funding or the holders of the Notes,
                                            as  the  case  may  be,  after  such
                                            withholding or deduction will not be
                                            less than the amount that would have
                                            been received in the absence of such
                                            withholding   or   deduction.    See
                                            "Description  of the  New  Notes  --

Redemption for Changes in Canadian
  Withholding Taxes.........................After GST USA has become the obligor
                                            on the Notes,  in the event that, as
                                            a   result   of   certain    changes
                                            affecting    Canadian    withholding
                                            taxes, GST becomes  obligated to pay
                                            additional   amounts  in  accordance
                                            with the  Indenture,  the Notes will
                                            be redeemable, as a whole but not in
                                            part,  at the  option  of GST at any
                                            time  at  100%  of  their  principal
                                            amount plus  accrued  interest.  See
                                            "Description  of the  New  Notes  --
                                            Optional Redemption."

Ranking  ...................................The   Notes  are   secured,   senior
                                            indebtedness  of  GST  Funding  and,
                                            once  assumed  by GST  USA,  will be
                                            secured,  senior indebtedness of GST
                                            USA.  The risk  exists  that GST USA
                                            may be unable to assume the Notes by
                                            May 13, 2000.  See "Risk  Factors --
                                            Possible  Inability  of  GST  USA to
                                            Assume,  GST to  Guarantee  and  GST
                                            Funding  to Redeem the  Notes."  The
                                            Note   Guarantee   will  be   senior
                                            unsecured indebtedness of GST. As of
                                            June  30,   1997,   GST  had  $587.2
                                            million of indebtedness outstanding,
                                            GST  USA  had   $557.7   million  of
                                            indebtedness   outstanding  and  GST
                                            Funding  had no  indebtedness  other
                                            than  the   Notes.   After  GST  USA
                                            assumes the Notes, the Notes and the
                                            Note  Guarantee  will be effectively
                                            subordinated  to all  liabilities of
                                            GST  USA's  subsidiaries,  including
                                            trade payables. As of June 30, 1997,
                                            (i)  the  subsidiaries  of  GST  USA
                                            other   than   GST    Funding    had
                                            approximately   $114.4   million  of
                                            liabilities (excluding  intercompany
                                            payables),  including  $90.5 million
                                            of   indebtedness   and   (ii)   the
                                            subsidiaries  of GST, other than GST
                                            USA and its subsidiaries  (including
                                            GST Funding), had approximately $8.8
                                            million  of  liabilities  (excluding
                                            intercompany  payables),   including
                                            $2.4  million of  indebtedness.  See

Certain Covenants...........................The   Indenture   contains   certain
                                            covenants which, among other things,
                                            prohibits GST Funding from incurring
                                            any  indebtedness   other  than  the
                                            Notes  and from  creating  any liens
                                            other than liens for the  benefit of
                                            the   holders  of  the   Notes.   In
                                            addition,  the  Indenture  restricts
                                            the   ability   of   GST   and   its
                                            Restricted  Subsidiaries  (including

                                  RISK FACTORS

         See "Risk  Factors"  beginning at page 15 for a  discussion  of certain
factors that should be considered in connection  with the Exchange  Offer and an
investment  in  the  New  Notes,  including  risks  related  to  historical  and
anticipated operating losses and negative EBITDA.

                                  RISK FACTORS

HISTORICAL AND ANTICIPATED FUTURE OPERATING LOSSES AND NEGATIVE EBITDA

         The Company has  incurred  and expects to continue to incur  increasing
operating  losses and  negative  EBITDA while it expands its business and builds
its customer  base. The Company has incurred  significant  increases in expenses
associated with these  activities and there can be no assurance that an adequate
customer  base with  respect to any or all of its  services  will be achieved or
sustained. The Company does not expect to achieve a significant market share for
any of its services.  The Company had a net loss of approximately $60.4 million,
an operating loss of  approximately  $42.6 million and negative  EBITDA of $33.9
million  for  Fiscal  1996 and a net loss of  approximately  $67.3  million,  an
operating  loss of  approximately  $54.7  million and  negative  EBITDA of $39.5
million for the nine months ended June 30, 1997.  There can be no assurance that
the Company will achieve or sustain  profitability or generate  positive EBITDA.
EBITDA  consists  of  loss  before  interest,  income  taxes,  depreciation  and
amortization  and other income and expense.  EBITDA is provided  because it is a
measure  commonly used in the  telecommunications  industry.  It is presented to
enhance an understanding of the Company's  operating results and is not intended
to represent  cash flow or results of operations in  accordance  with  generally
accepted  accounting  principles  for  the  periods  indicated.   See  "Selected
Financial Data" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

         At  September  30,  1996,  the Company had a U.S.  net  operating  loss
carryforward  of  approximately  $45.0 million and a Canadian net operating loss
carryforward of approximately  Cdn.$6.8 million.  While such loss  carryforwards
are available to offset future taxable  income of the Company,  the Company does
not expect to  generate  sufficient  taxable  income so as to  utilize  all or a
substantial  portion  of such  loss  carryforwards  prior to  their  expiration.
Further,  the  utilization  of net operating loss  carryforwards  against future
taxable income is subject to limitation if the Company experiences  an"ownership
change" as  defined in Section  382 of the  Internal  Revenue  Code of 1986,  as
amended (the "Code") and the analogous  provision of the Income Tax Act (Canada)
(the"Canada Act").

DEVELOPMENT AND EXPANSION RISK AND POSSIBLE INABILITY TO MANAGE GROWTH

         The Company is in the early  stages of its  operations.  Certain of its
networks have only recently become commercially  operational and the Company has
only  recently  begun to deploy  switches  in its  networks.  The success of the
Company will depend,  among other things,  upon the Company's  ability to assess
potential  markets,  design fiber backbone routes that provide ready access to a
substantial  customer base,  secure  financing,  obtain required  rights-of-way,
building access and governmental permits, implement expanded interconnection and
collocation  with  facilities  owned by ILECs and achieve a sufficient  customer
base, and upon subsequent  developments in state and federal regulations.  There
can be no assurance that any networks to be developed or further  developed will
be  completed  on  schedule,  at a  commercially  reasonable  cost or within the
Company's  specifications.  In addition, the expansion of the Company's business
has  involved and is expected to continue to involve  acquisitions,  which could
divert the resources and management time of the Company and require  integration
with the  Company's  existing  operations.  There can be no  assurance  that any
acquired business will be successfully  integrated into the Company's operations
or that any such business will meet the  Company's  expectations.  The Company's
future  performance will depend,  in part, upon its ability to manage its growth
effectively,  which will  require it to  continue to  implement  and improve its
operating,  financial and accounting  systems,  to expand,  train and manage its
employee base and to effectively manage the integration of acquired  businesses.
These factors and others could  adversely  affect the expansion of the Company's
customer base and service offerings. The Company's inability either to expand in
accordance with its plans or to manage its growth could have a material  adverse
effect on its  business,  financial  condition  and results of  operations.  See
"Business."

SIGNIFICANT CAPITAL REQUIREMENTS

   
         The Company  believes  that the net proceeds of the May  Offering,  the
Special  Warrant  Offering,  the NACT Offering and the Princes Gate  Investment,
other securities offering, if any, consummated in the future, together with cash
on hand and  borrowings  expected to be available  under both the Tomen Facility
and the  equipment  financing  arranged  with  Siemens  and NTFC,  will  provide
sufficient funds for the Company to expand its business as presently planned and
to fund its operating  expenses  through June 1998.  The Company also expects to
require  additional  financing.  In  the  event  that  the  Company's  plans  or
assumptions change or prove to be inaccurate,  or the foregoing sources of funds
prove to be insufficient to fund the Company's growth and operations,  or if the
Company consummates acquisitions, the Company may be required to seek additional
capital . The Company may also seek to take advantage of favorable conditions in
the capital markets.  Sources of financing may include public or private debt or
equity  financing by the Company or its  subsidiaries,  sales of assets or other
financing arrangements. There can be no assurance that such additional financing
would be available to the Company or, if available, that it could be obtained on
acceptable terms or within the limitations  contained in the Company's financing
arrangements.  Failure to obtain  such  financing  could  result in the delay or
abandonment of some or all of the Company's  development and expansion plans and
expenditures  and could  have a material  adverse  effect on the  Company.  Such
failure  could also  limit the  ability of the  Company  to make  principal  and
interest  payments on its  outstanding  indebtedness,  including the Notes.  The
Company  has no working  capital or other  credit  facility  under  which it may
borrow for working capital and other general corporate purposes. There can be no
assurance that such a facility will be available to the Company in the future or
that if such a facility were available,  that it would be available on terms and
conditions acceptable to the Company. See "Management's  Discussion and Analysis
of  Financial  Condition  and  Results  of  Operations--Liquidity   and  Capital
Resources."
    

SUBSTANTIAL INDEBTEDNESS

   
         At June 30, 1997, the Company had  outstanding on a consolidated  basis
approximately  $587.2  million of  indebtedness.  In addition,  the accretion of
original  issue  discount will cause a $130.4  million  increase in  liabilities
relating to the 1995 Notes by December  15,  2000.  The  Indenture  and the 1995
Indentures limit, but do not prohibit, the incurrence of additional indebtedness
by the Company.  At June 30, 1997, the Company had $67.7 million of availability
under  the Tomen  Facility  to  finance  the  development  and  construction  of
additional  networks,  if and to the extent that proposals for funding  projects
are approved by Tomen.  On September 30, 1997,  Tomen  provided the Company with
$40.5  million  of  financing   under  the  Tomen   Facility  for  the  Hawaiian
inter-island  submarine network and various other  terrestrial  installations in
the Hawaiian islands.  See "Recent  Developments."  The Company expects to incur
substantial additional  indebtedness in the future. The Company has entered into
the Siemens  Loan  Agreement  that  provides  for up to an  aggregate  of $226.0
million in equipment  financing,  of which $116.0 million is presently available
to the Company  ($4.5  million of which had been  provided as of June 30, 1997).
The Company may seek to increase the amount available up to $226.0 million on an
as-needed   basis,   subject  to  the  negotiation  and  execution  of  mutually
satisfactory  documentation.  The  Company  also  entered  into  the  NTFC  Loan
Agreement for up to $50.0 million of  additional  equipment  financing (of which
$44.6 million had been provided as of June 30, 1997).  There can be no assurance
that any  additional  financing  will be available to the Company on  acceptable
terms  or at all.  See  "Description  of  Certain  Indebtedness  and  Redeemable
Preferred Shares."
    

         The  level  of  the  Company's   indebtedness   could  have   important
consequences to its future prospects,  including the following: (i) limiting the
ability  of the  Company  to obtain any  necessary  financing  in the future for
working  capital,  capital  expenditures,  debt  service  requirements  or other
purposes;  (ii) requiring that a substantial  portion of the Company's cash flow
from  operations,  if any,  be  dedicated  to the  payment of  principal  of and
interest  on  its  indebtedness  and  other  obligations;   (iii)  limiting  its
flexibility  in planning for, or reacting to changes in, its business;  (iv) the
Company will be more highly  leveraged than some of its  competitors,  which may
place it at a competitive disadvantage;  and (v) increasing its vulnerability in
the event of a  downturn  in its  business.  See  "Management's  Discussion  and
Analysis of Financial Condition and Results of Operations."

POSSIBLE INABILITY TO SERVICE DEBT

         In  connection  with the buildout of its networks and expansion of CLEC
services,  the Company has been experiencing  increasing negative EBITDA and the
Company's earnings before fixed charges were insufficient to cover fixed charges
for the nine months  ended June 30,  1997,  Fiscal 1996 and Fiscal 1995 by $76.5
million,  $62.9  million  and  $13.8  million,  respectively.  There  can  be no
assurance  that the Company  will be able to improve its  earnings  before fixed
charges or EBITDA or that it will be able to meet its debt service  obligations.
As the  Company  does not  currently  have a  revolving  credit  facility,  if a
shortfall  occurs,  alternative  financing  would be  necessary in order for the
Company to meet its liquidity  requirements  and there can be no assurance  that
such  financing  would be  available.  In such  event,  the  Company  could face
substantial liquidity problems.  In addition,  the Company anticipates that cash
flow from  operations will be insufficient to repay the 1995 Notes and the Notes
at maturity in full and that such indebtedness  will need to be refinanced.  All
of the  Company's  existing  indebtedness  matures  prior to the  Notes  and any
additional indebtedness incurred in the future may mature prior to the Notes and
will need to be refinanced  prior to the maturity of the Notes.  There can be no
assurance that the Company will be able to effect such refinancings. The ability
of the Company to meet its obligations and to effect such  refinancings  will be
dependent upon, among other things, the future performance of the Company, which
will be subject to prevailing economic conditions and to financial,business  and
other factors,  including factors beyond the control of the Company.  Failure by
the  Company  to  meet  its  obligations  could  result  in  a  default  on  its
indebtedness,  including  the 1995 Notes and the Notes,  which would  permit the
holders of  substantially  all of the Company's  indebtedness  to accelerate the
maturity  thereof.  In such  event,  the  Company  may  not be able to meet  its
obligations on the Notes. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and  "Description  of Certain  Indebtedness
and Redeemable Preferred Shares."

INSUFFICIENCY OF ACQUIRED EQUIPMENT TO SATISFY THE NOTES UPON LIQUIDATION

         In the event that GST Funding (or upon the  assumption  of the Notes by
GST USA,  GST USA)  were to be  unable  to pay  amounts  due under the Notes and
(following the assumption of the Notes by GST USA) GST were to default under the
Note  Guarantee,  holders of the Notes  would be entitled  to  foreclose  on the
Pledged   Securities  or  Acquired  Equipment  and  the  Initial  Note  and  the
Intercompany  Notes  (collectively,  the  "Collateral") to satisfy  indebtedness
under the Notes.  A substantial  portion of the value of the Acquired  Equipment
will consist of the cost of designing,  constructing,  acquiring, installing and
integrating such equipment. In addition, because the telecommunications industry
is  subject  to  rapidly   changing   technologies   and  frequent  new  product
introductions,  the value of the Acquired  Equipment may decline over time.  The
value of the Acquired  Equipment  may also decline due to the  availability  and
price of competing  products and technologies,  evolving industry  standards and
regulatory requirements and depreciation. Further, a foreclosure will not result
in the  realization  of the full fair  market  value of the  Acquired  Equipment
because such value may be affected by the removal from an integrated  network of
the Acquired  Equipment and because of costs  associated with such  foreclosure.
Therefore, in the event of foreclosure, the value of the Acquired Equipment will
not satisfy the Notes in full.

         Further,  the right of the  Trustee  to  repossess  and  dispose of the
Collateral  upon the  occurrence  of a  default  under the Notes is likely to be
significantly  impaired by applicable  bankruptcy law if a bankruptcy proceeding
were to be  commenced  by or  against  GST  Funding  or,  after  the sale of any
Acquired  Equipment to GST USA, GST USA, prior to the Trustee's  having disposed
of the  Collateral.  Under Title XI of the United  States Code (the  "Bankruptcy
Code"),  a secured  creditor such as the Trustee is prohibited from disposing of
security repossessed from a debtor in a bankruptcy case without bankruptcy court
approval.  Moreover,  the  Bankruptcy  Code  prohibits a secured  creditor  from
disposing  of  collateral  even  though  the  debtor  is in  default  under  the
applicable  debt   instruments  if  the  secured  creditor  is  given  "adequate
protection." The meaning of the term "adequate protection" may vary according to
circumstances, but it is intended in general to protect the value of the secured
creditor's  interest  in the  collateral  and may include  cash  payments or the
granting  of  additional  security,  if and at such  times  as the  court in its
discretion  determines,  for any  diminution of the value of the collateral as a
result of the stay of disposition during the pendency of the bankruptcy case. In
view of the lack of a precise  definition of the term "adequate  protection" and
the broad  discretionary  powers of a  bankruptcy  court,  it is  impossible  to
predict how long

                                      -17-

<PAGE>

payment under the Notes could be delayed following  commencement of a bankruptcy
case,  whether or when the Trustee could dispose of the Collateral or whether or
to what extent holders of Notes would be compensated for any delay in payment or
loss  of  value  of  the  Collateral   through  the   requirement  of  "adequate
protection."

         In addition,  notwithstanding anything to the contrary described above,
unless an event of  default  under the  Indenture  shall  have  occurred  and be
continuing,  GST  Funding or GST USA, as the case may be, will have the right to
remain in possession and retain exclusive control of the Acquired Equipment,will
have the right to freely utilize the Acquired  Equipment and will have the right
to collect, invest and dispose of any income thereon.

MAINTENANCE OF SECURITY INTEREST IN COLLATERAL

         Under the terms of a Collateral  Pledge and Security  Agreement made by
GST Funding to the  Trustee  for the  benefit of the  holders of the Notes,  GST
Funding  and,  upon the sale of the  Acquired  Equipment to GST USA, GST USA are
required  to secure  the  Notes and the  Intercompany  Notes,  respectively,  by
granting  liens  on the  Acquired  Equipment.  GST  Funding  and GST USA will be
required  to file UCC-1  Financing  Statements  in each state in which  Acquired
Equipment will be located and to maintain such security  filings in effect under
the relevant provisions of the Uniform Commercial Code as in effect in each such
state.  Although  failure to do so may  result in an event of default  under the
Notes,  such failure may allow other creditors of GST Funding or, after the sale
of the  Acquired  Equipment  to GST USA,  GST USA,  or owners or  mortgagees  of
property on which  Acquired  Equipment is  installed,  to obtain  rights in such
Acquired  Equipment  that are equal or  superior  to those of the holders of the
Notes.  This could result in some or all of the value of the Acquired  Equipment
not being  available  to the  holders of the Notes to  satisfy  the Notes in the
event of a default.  Such failure could arise,  among other reasons,  because of
the failure to file  continuation  statements  prior to the  expiration  of each
five-year period after the initial filing.

POSSIBLE  INABILITY OF GST USA TO ASSUME,  GST TO  GUARANTEE  AND GST FUNDING TO
REDEEM THE NOTES

         The  Indenture  provides  that GST USA will  assume and become a direct
obligor  on the  Notes and GST will  guarantee  the  Notes on May 13,  2000,  or
earlier,  if  permitted  under the 1995  Indentures.  The  Indenture  provisions
requiring GST USA to assume,  and GST to guarantee,  the Notes,  unless consents
are obtained, require GST to repay all indebtedness then outstanding that by its
terms would prohibit such assumption or guarantee. If on May 13, 2000 GST USA is
prohibited by the 1995 Indentures from assuming all of the Notes,  the Indenture
provides  that GST Funding will  redeem,  upon not less than 10 nor more than 30
days' notice, the portion of the Notes that cannot be assumed,  at 101% of their
principal amount plus accrued and unpaid interest to the date of redemption. The
failure of GST USA to assume the Notes, or of GST to guarantee the Notes,  would
result in a default  under the  Notes.  Further,  GST  Funding  may not have the
capital resources to redeem the portion of the Notes that cannot be assumed. See
"Description of the New Notes -- Events of Default."

         A default  under  the Notes  could  result  in a  default  under  other
indebtedness  of the Company,  including the 1995 Notes,  which would permit the
holders of  substantially  all of the Company's  indebtedness  to accelerate the
maturity  thereof.  In the event of a default on the Notes prior to the time GST
USA becomes a direct  obligor on the Notes,  and in the event the holders of the
Notes or the Trustee  foreclose  on the  collateral  securing the Notes and such
collateral is insufficient to pay all amounts due on the Notes, the holders will
not have a claim against GST USA or GST under the Notes or the Notes  Guarantee,
other than under the Initial Note and the  Intercompany  Notes pledged to secure
the Notes.  However,  the  obligations of GST USA under the Initial Note and the
Intercompany Notes, and of GST under the guarantee thereof, may be less than the
principal  of and  accrued  interest  on the  Notes.  To the  extent  there is a
shortfall,  GST USA and GST will not be  liable  to  holders  of the  Notes  for
amounts  due on the  Notes  prior to the  time  that  GST USA  becomes  a direct
obligor.  GST Funding will have no assets other than the collateral securing the
Notes,  which,  upon  foreclosure  after a default  upon the  Notes,  may not be
sufficient  to repay all  amounts  due on the Notes.  See "--  Insufficiency  of
Acquired Equipment to Satisfy the Notes upon Liquidation."

FINANCIAL AND OPERATING RESTRICTIONS IMPOSED BY EXISTING INDEBTEDNESS

         The Company's financing  arrangements impose significant  operating and
financial  restrictions on the Company. Such restrictions affect, and in certain
cases  significantly  limit or prohibit,  among other things, the ability of the
Company to incur additional  indebtedness or to create liens on its assets, sell
assets, engage in mergers or acquisitions or make investments. Failure to comply
with any such covenant could result in a default thereunder,  which could result
in  an  acceleration  of  such   indebtedness.   See   "Description  of  Certain
Indebtedness and Redeemable Preferred Shares."

STRUCTURE  OF GST FUNDING,  GST USA AND GST;  SECURED  INDEBTEDNESS;  RANKING OF
NOTES

         GST and GST USA are each holding  companies and none of GST, GST USA or
GST Funding conducts any operations.  The principal assets of GST consist of the
common stock of GST USA, GST Action Telecom, GST Call America and TotalNet,  and
the principal asset of GST USA consists of the common stock of its subsidiaries.
Neither  GST USA nor GST will be liable on the Notes  until they are  assumed by
GST USA. GST USA must rely upon payments from its  subsidiaries  to generate the
funds necessary to meet its  obligations,  including the payment of principal of
and  interest on the Initial  Notes and the  Intercompany  Notes and,  after its
assumption  thereof,  the Notes. GST must rely upon dividends and other payments
from GST Action Telecom,  GST Call America,  TotalNet and GST USA's subsidiaries
should  it be  required  to make any  payments  under  the Note  Guarantee.  The
subsidiaries,  however,  are  legally  distinct  from  GST and GST USA and  such
subsidiaries  will have no obligation,  contingent or otherwise,  to pay amounts
due pursuant to the Notes or the Note  Guarantee or to make funds  available for
such payment, although GST USA will be obligated to make payments on the Initial
Note and any Intercompany Notes. See "-- Possible Inability of GST USA to Assume
and GST to Guarantee the Notes." GST USA's  subsidiaries  will not guarantee the
Notes.  The ability of GST USA's  subsidiaries  to make such payments to GST USA
will be subject to, among other things,  the availability of funds, the terms of
such  subsidiaries'  indebtedness and applicable state laws.  Pursuant to credit
agreements under the Tomen Facility, GST USA's subsidiaries that own and operate
the  Southern  California,Tucson  and  Albuquerque  networks  may  not  pay  any
dividends or make any distributions on their capital stock.  Subsequent  network
financings   under  the  Tomen   Facility  are   expected  to  include   similar
prohibitions.

         Claims  of  creditors  of  GST  USA's  subsidiaries,   including  trade
creditors,  will generally  have priority as to the assets of such  subsidiaries
over the claims of GST Funding, GST USA and the holders of GST Funding's and GST
USA's  indebtedness,  including the Notes,  the Initial Note,  the  Intercompany
Notes and the Note Guarantee.  Accordingly, after GST USA becomes the obligor on
the Notes, the Notes and the Note Guarantee will be effectively  subordinated to
the  liabilities  (including  trade  payables) of the  subsidiaries  of GST USA,
except  with  respect  to  any  Acquired  Equipment.   At  June  30,  1997,  the
subsidiaries of GST USA other than GST Funding had approximately  $114.4 million
of liabilities  (excluding  intercompany  payables),  including $90.5 million of
indebtedness,  all of which was secured.  At June 30, 1997, the  subsidiaries of
GST,  other  than GST USA and its  subsidiaries  (including  GST  Funding),  had
approximately  $8.8 million of liabilities  (excluding  intercompany  payables),
including  $2.4  million  of  indebtedness.  To the  extent  the  Collateral  is
foreclosed upon and is insufficient to repay all amounts due with respect to the
Notes, the holders of the Notes would have a general, unsecured,  unsubordinated
claim against the Issuer for the  shortfall.  See  "--Insufficiency  of Acquired
Equipment to Satisfy the Notes upon  Liquidation"  and"-- Possible  Inability of
GST USA to Assume and GST to Guarantee the Notes."

DIFFICULTIES IN IMPLEMENTING LOCAL AND ENHANCED SERVICES

         The Company has begun,  and plans to continue,  to deploy high capacity
digital  switches  in the  cities  in which  it  operates  or  plans to  operate
networks,  as well as in  certain  cities  where the  Company  will rely on ILEC
facilities for transmission.  This will enable the Company to offer a variety of
switched  access  services,  enhanced  services and local dial tone. The Company
expects  negative  EBITDA from its switched  services  during the 24 to 36 month
period after a switch is deployed.  For switches  operating in conjunction  with
the Company's networks,  the Company expects operating margins to improve as the
network is expanded and larger volumes of traffic are

                                      -19-

<PAGE>

   
carried on the  Company's  network.  For switches  operating in cities where the
Company  will  rely  on ILEC  facilities  for  transmission,  the  Company  will
experience  lower gross  margins under  current ILEC pricing  tariffs.  Although
under the  Telecommunications  Act the ILECs will be required to unbundle  local
tariffs  and to  permit  the  Company  to  purchase  only  the  origination  and
termination services it needs, thereby decreasing operating expenses,  there can
be no assurance  that such  unbundling  will be effected in a timely  manner and
result in prices favorable to the Company. In addition, the Company's ability to
successfully  implement  its  switched and  enhanced  services  will require the
negotiation of resale  agreements with ILECs and other CLECs and the negotiation
of  interconnection  agreements with ILECs,  which can take  considerable  time,
effort and expense.
    

         In  August  1996,  the  FCC  released  a  decision   implementing   the
interconnection  portions of the  Telecommunications  Act (the  "Interconnection
Decision").  The  Interconnection  Decision  establishes  rules for  negotiating
interconnection agreements and guidelines for review of such agreements by state
public  utilities  commissions.  On July 18,  1997,  the United  States Court of
Appeals for the Eighth Circuit (the "Eighth  Circuit")  vacated certain portions
of the Interconnection  Decision,  including  provisions  establishing a pricing
methodology  for unbundled  elements and a procedure  permitting new entrants to
"pick  and  choose"  among  various   provisions  of  existing   interconnection
agreements  between ILECs and their  competitors.  The Company had  negotiated a
number of  interconnection  agreements  with ILECs prior to this Eighth  Circuit
decision.  The  Eighth  Circuit  decision  creates  uncertainty  about the rules
governing pricing, terms and conditions of interconnection  decisions, and could
make negotiating and enforcing such agreements more difficult and protracted and
may require renegotiation of existing agreements. There can be no assurance that
the  Company  will  be  able  to  obtain  interconnection  agreements  on  terms
acceptable  to the Company.  The FCC has  announced  that it will seek a writ of
certiorari from the Supreme Court. See"-- Competition."

         The  Company is a recent  entrant  into the newly  created  competitive
local telecommunications  services industry. The local dial tone services market
in most states was only recently opened to competition due to the passage of the
Telecommunications  Act and  related  regulatory  rulings.  There  are  numerous
operating  complexities  associated with providing  these services.  The Company
will be required to develop new products,  services and systems and will need to
develop new marketing initiatives to sell these services.

         The Company's  switched  services may not be  profitable  due to, among
other  factors,  lack of customer  demand,  inability  to secure  access to ILEC
facilities  at  acceptable  rates,  competition  from  other  CLECs and  pricing
pressure  from the ILECs.  The Company  has very  limited  experience  providing
switched  access and local dial tone services and there can be no assurance that
the Company  will be able to  successfully  implement  its switched and enhanced
services strategy. See "Business -- Telecommunications Services Strategy."

   
         Implementation of the Company's  switched and enhanced services is also
subject to the Company's ability to obtain equipment  financing for switches and
upon equipment  manufacturers'  ability to meet the Company's switch  deployment
schedule.  Although  as of June 30,  1997,  the  Company  had $111.5  million of
proceeds  available under the Siemens Loan Agreement and $5.4 million  available
under the NTFC Loan  Agreement,  there can be no assurance that switches will be
deployed on the schedule contemplated by the Company or that, if deployed,  such
switches will be utilized to the degree contemplated by the Company.
    

RECENT COMMENCEMENT OF INTEGRATED MARKETING EFFORT

         The Company has only recently begun an integrated  marketing  effort of
its telecommunication service offerings.  Historically, the Company has marketed
its  access  services  primarily  to  long  distance  carriers  and  significant
end-users of  telecommunications  services,  and its long  distance  services to
small businesses and consumers. Although the Company expects to market a variety
of  telecommunications  services  to  all  of  its  customers,  there  can be no
assurance  that the Company will be able to attract and retain new  customers or
retain and sell additional services to existing customers.


                                      -20-

DEPENDENCE ON KEY CUSTOMERS

         The  Company's  five  largest  telecommunications   services  customers
accounted for approximately 22.0%, 46.9% and 26.8% of the Company's consolidated
telecommunications  services  revenues  for the nine months ended June 30, 1997,
Fiscal  1996  and  Fiscal  1995,  respectively.  During  Fiscal  1995,  a former
customer,  which  customer is presently the subject of a bankruptcy  proceeding,
accounted for 5.3% of the Company's  consolidated  revenues.  It is  anticipated
that during the early  stages of  development  of  individual  networks,  before
obtaining  a  sufficient  amount  of  end-user  revenues,  the  Company  will be
dependent  on a  limited  number of long  distance  carriers  for a  significant
portion of its local  revenues.  While long  distance  carriers have high volume
requirements  and have utilized  CLECs,  they generally are more price sensitive
than  end-users.  The five  largest  customers  of the  Company's  manufacturing
operations  accounted for 13.4% and 16.1% of the Company's  consolidated product
revenues for Fiscal 1996 and Fiscal 1995 respectively.  The loss of, or decrease
of  business  from,  one or more  significant  customers  could  have a material
adverse effect on the business, financial condition and results of operations of
the Company.  See "Management's  Discussion and Analysis of Financial  Condition
and Results of Operations."

RISKS RELATING TO LONG DISTANCE BUSINESS

         For Fiscal 1996 and the nine months ended June 30, 1997,  long distance
represented  56.0% and 60.0% of the  Company's  consolidated  telecommunications
services  revenues,  respectively.  The  long  distance  business  is  extremely
competitive  and prices  have  declined  substantially  in recent  years and are
expected to continue to decline.  In addition,  the long  distance  industry has
historically had a high average churn rate, as customers  frequently change long
distance  providers  in response to the  offering of lower rates or  promotional
incentives by  competitors.  See "--  Competition."  The Company relies on other
carriers to provide  transmission and termination services for a majority of its
long  distance  traffic.  The Company has resale  agreements  with long distance
carriers to provide it with  transmission  services.  Such agreements  typically
provide  for the resale of long  distance  services  on a per minute  basis with
minimum volume  commitments.  Negotiation of these agreements involves estimates
of future  supply and demand for  transmission  capacity as well as estimates of
the calling pattern and traffic levels of the Company's future customers. In the
event  the  Company  fails to meet its  minimum  volume  commitments,  it may be
obligated to pay underutilization charges and in the event it underestimates its
need for transmission  capacity,  the Company may be required to obtain capacity
through more  expensive  means.  See  "Management's  Discussion  and Analysis of
Financial Condition and Results of Operations -- Overview."

DEPENDENCE ON BILLING, CUSTOMER SERVICES AND INFORMATION SYSTEMS

         Sophisticated  information  and  processing  systems  are  vital to the
Company's  growth and its ability to monitor costs,  bill  customers,  provision
customer  orders and achieve  operating  efficiencies.  Billing and  information
systems  for the  Company's  historical  lines of  business  have been  produced
largely  in-house with partial  reliance on third-party  vendors.  These systems
have generally met the Company's needs due in part to the low volume of customer
billing. As the Company transitions to the provisioning of local services and as
its long  distance  and  Internet  operations  continue to  expand,the  need for
sophisticated billing and information systems will increase  significantly.  The
Company's plans for the development  and  implementation  of its billing systems
rely, for the most part, on the delivery of products and services by third party
vendors. Similarly, the Company is developing customer call centers to provision
service  orders.  Information  systems  are  vital  to the  success  of the call
centers,  and the  information  systems for these call centers are largely being
developed by third party vendors.  Failure of these vendors to deliver  proposed
products and services in a timely and effective manner and at acceptable  costs,
failure  of the  Company  to  adequately  identify  all of its  information  and
processing  needs,  failure of the Company's  related  processing or information
systems,  or the failure of the Company to upgrade  systems as  necessary  could
have a  material  adverse  effect on the  ability  of the  Company  to reach its
objectives, its financial condition and its results of operations.

COMPETITION

         The  telecommunications   industry  is  highly  competitive.   In  most
markets,the  Company's  principal  competitor for local exchange services is the
Regional Bell Operating  Company  ("RBOC") or GTE Corporation and its affiliated
companies  (collectively,  the "GTE  Companies").  Other competitors may include
other CLECs,  microwave  and  satellite  carriers,  wireless  telecommunications
providers and private networks built by large end-users.  Potential  competitors
(using similar or different  technologies)  include cable television  companies,
utilities and RBOCs outside their current local service areas. In addition,  the
Company  anticipates future competition from large long distance carriers,  such
as AT&T  Corp.  ("AT&T"),  MCI  Communications  Corporation  ("MCI")  and Sprint
Corporation  ("Sprint"),  which  have begun to offer  integrated  local and long
distance  telecommunications  services.  AT&T also has  recently  announced  its
intention to offer local services using a new wireless technology. Consolidation
of telecommunications  companies and the formation of strategic alliances within
the telecommunications industry, as well as the development of new technologies,
could give rise to  significant  new  competitors  to the  Company.  As a recent
entrant in the integrated  telecommunications services industry, the Company has
not achieved and does not expect to achieve a  significant  market share for any
of its services.  In  particular,  the RBOCs,  the GTE Companies and other local
telephone companies have long-standing  relationships with their customers, have
financial, technical and marketing resources substantially greater than those of
the Company,  have the potential to subsidize competitive services with revenues
from a variety  of  businesses  and  currently  benefit  from  certain  existing
regulations  that favor the ILECs over the  Company in certain  respects.  While
recent  regulatory   initiatives,which  allow  CLECs  such  as  the  Company  to
interconnect with ILEC facilities,  provide increased business opportunities for
the  Company,  such  interconnection  opportunities  have  been  accompanied  by
increased pricing flexibility for and relaxation of regulatory  oversight of the
ILECs.

         To the extent the Company  interconnects with and uses ILEC networks to
service its  customers,  the Company will be dependent  upon the  technology and
capabilities  of the  ILECs  to meet  certain  telecommunications  needs  of the
Company's  customers  and to maintain  its service  standards.  The Company will
become increasingly dependent on interconnection with ILECs as switched services
become a greater percentage of the Company's  business.  The  Telecommunications
Act imposes interconnection  obligations on ILECs, but there can be no assurance
that the  Company  will be able to obtain the  interconnection  it  requires  at
rates,  and on terms and  conditions,  that permit the Company to offer switched
services at rates that are  simultaneously  competitive and profitable.  See "--
Difficulties in Implementing Local and Enhanced Services." In the event that the
Company  experiences  difficulties  in  obtaining  high  quality,  reliable  and
reasonably  priced service from the ILECs, the  attractiveness  of the Company's
services to its customers could be impaired.

         The  long   distance   telecommunications   industry   has   relatively
insignificant  barriers  to  entry,  numerous  entities  competing  for the same
customers  and a high average churn rate,  as customers  frequently  change long
distance  providers  in response to the  offering of lower rates or  promotional
incentives by  competitors.  The Company  competes  with major  carriers such as
AT&T,  MCI and Sprint,  as well as other  national  and regional  long  distance
carriers and resellers,  many of whom are able to provide services at costs that
are lower than the  Company's  current  costs.  In addition,  as a result of the
Telecommunications Act, the RBOCs are expected to become competitors in the long
distance telecommunications industry both outside of their service territory and
upon the satisfaction of certain conditions, within their service territory. SBC
has challenged the  constitutionality of the provisions  conditioning RBOC entry
into in-region long distance service.  See "Business -- Regulation." As a result
of the Company's  acquisition of Action Telcom,  GST Call America,  TotalNet and
the business of Texas-Ohio,  the Company's long distance operations will account
for a significant portion of the Company's  revenues.  See "-- Risks Relating to
Long Distance  Business."  The Company  believes that the principal  competitive
factors  affecting its long distance  operations are pricing,  customer service,
accurate  billing,  clear pricing  policies and, to a lesser extent,  variety of
services. The ability of the Company to compete effectively will depend upon its
continued  ability to maintain  high quality,  market driven  services at prices
generally  equal to or below those charged by its  competitors.  To maintain its
competitive posture,the Company believes that it must be in a position to reduce
its prices in order to meet  reductions  in rates,  if any, by others.  Any such
reductions could adversely affect the Company.

<PAGE>

         The  Internet  services  market  is  highly  competitive.  There are no
substantial  barriers to entry,  and the Company expects that  competition  will
continue to intensify. The Company's competitors in this market include Internet
service providers, other telecommunications companies, online services providers
and  Internet  software  providers.  Many  of  these  competitors  have  greater
financial,  technological  and marketing  resources than those  available to the
Company.

         The market for  telecommunications  products is highly  competitive and
subject to rapid  technological  change. NACT expects competition to increase in
the future from existing competitors in the distributed switching systems market
and from other  companies  that may enter  NACT's  existing  or future  markets,
including  major central office switch vendors.  NACT currently  competes with a
number of lower capacity switch  manufacturers  such as  Communications  Product
Development,  Inc. ("CPDI"), Integrated Telephony Products, Inc. ("ITP") and PCS
Telecom,  Inc.  ("PCS  Telecom").  NACT also  competes  with  providers  of open
architecture  (programmable)  hardware switching  platforms that are enhanced by
applications  providers  and value added  resellers.  Such  competitors  include
Excel, Inc. ("Excel"), which has agreements with software application providers.
As NACT's  business  develops  and it seeks to market its  switches to a broader
customer   base,   NACT's    competitors   may   include   larger   switch   and
telecommunications  equipment  manufacturers  such as Lucent  Technologies Inc.,
Siemens AG, Alcatel Alsthom Compagnie,  Ericcson and Northern Telecom, Ltd. Many
of  NACT's  current  and  potential   competitors  have  substantially   greater
financial,  technical and marketing resources than NACT.  Increased  competition
could materially and adversely affect NACT's business,  financial  condition and
results of operations  through price reductions and loss of market share.  There
can be no assurance  that NACT will be able to continue to compete  successfully
with its existing  competitors  or that it will be able to compete  successfully
with new competitors.

         The  recent  World  Trade  Organization   ("WTO")  agreement  on  basic
telecommunications   services  could  increase  the  Company's  competition  for
telecommunication  services both  domestically and  internationally.  Under this
agreement,  the United States and other members of the WTO committed  themselves
to opening their telecommunications markets to competition and foreign ownership
and  to   adopting   regulatory   measures   to  protect   competitors   against
anticompetitive  behavior by dominant  telephone  companies,  effective  in some
cases as early as  January  1,  1998.  See  "Business  --  Competition"  and "--
Regulation."

GOVERNMENT REGULATION

         The  Company's  networks and the provision of switched and private line
services are subject to significant  regulation at the federal,  state and local
levels.  Delays in receiving required  regulatory  approvals or the enactment of
new adverse  regulation or regulatory  requirements  may have a material adverse
effect upon the Company.  The FCC exercises  jurisdiction  over the Company with
respect to interstate and international services. Additionally, the Company must
file tariffs  with the FCC. On October 29, 1996,  the FCC approved an order that
eliminates the tariff filing  requirements for interstate domestic long distance
service provided by non-dominant  carriers such as the Company.  On February 13,
1997,  the United  States Court of Appeals for the District of Columbia  Circuit
stayed  the  FCC  order.  In  addition,   the  Company  must  obtain  prior  FCC
authorization  for installation  and operation of  international  facilities and
international  long distance  services.  State regulatory  commissions  exercise
jurisdiction over the Company to the extent it provides intrastate services.  As
such a provider,  the Company is  required  to obtain  regulatory  authorization
and/or  file  tariffs  at  state  agencies  in most of the  states  in  which it
operates.   Local  authorities   regulate  the  Company's  access  to  municipal
rights-of-way.  The networks are also subject to numerous local regulations such
as building codes and  licensing.  Such  regulations  vary on a city by city and
county by county basis.  See"Business -- Regulation."  There can be no assurance
that the FCC or state commissions will grant required  authority or refrain from
taking  action  against  the  Company if it is found to have  provided  services
without obtaining the necessary authorizations.  If authority is not obtained or
if tariffs are not filed,  or are not updated,  or otherwise do not fully comply
with the tariff  filing  rules of the FCC or state  regulatory  agencies,  third
parties or regulators could challenge these actions. Such challenges could cause
the Company to incur substantial legal and administrative expenses.

                                      -23-

         The Telecommunications  Act provides for a significant  deregulation of
the domestic  telecommunications  industry,  including the local exchange,  long
distance and cable television  industries.  The  Telecommunications  Act remains
subject  to  judicial  review  and  additional  FCC  rulemaking,  and thus it is
difficult  to predict what effect the  legislation  will have on the Company and
its operations.  There are currently many regulatory  actions underway and being
contemplated by federal and state authorities regarding  interconnection pricing
and other  issues  that could  result in  significant  changes  to the  business
conditions in the  telecommunications  industry.  There can be no assurance that
these changes will not have a material adverse effect upon the Company.

         In addition to requirements placed on ILECs, the Telecommunications Act
subjects  the  Company  to  certain  federal  regulatory  requirements  upon the
Company's  provision of local exchange service in a market.  All ILECs and CLECs
must  interconnect  with other  carriers,  provide  nondiscriminatory  access to
rights-of-way,  offer  reciprocal  compensation  for  termination of traffic and
provide dialing parity and telephone number portability.  The Telecommunications
Act also requires all telecommunications  carriers to ensure that their services
are  accessible  to and  usable by persons  with  disabilities.  Under  recently
announced FCC rules,  the Company and other CLECs will be required to contribute
to a universal  service  fund  provided for in the  Telecommunications  Act. The
decision  adopting these rules has been appealed.  The FCC recently issued rules
that require ILECs to reduce access charges paid by long distance carriers. Some
of the  changes  may also  result  in  increased  costs to the  Company  for the
"transport" component of access charges.  Pricing flexibility for the ILECs with
respect to access  charges is not yet  resolved.  No assurance can be given that
the changes to current regulations or the adoption of new regulations  (pursuant
to the Telecommunications Act or otherwise) by the FCC or state commissions will
not have a material adverse effect on the Company.

   
         In  addition,   federal  regulations  impose  restrictions  on  foreign
ownership of communications  service providers utilizing radio frequencies.  The
operations of GST Telecom Hawaii, Inc. ("GST Hawaii"), a wholly-owned subsidiary
of GST that  conducts  the  Company's  business  in  Hawaii,  use,  among  other
transmission  facilities,  microwave radio facilities  operating pursuant to FCC
licenses granted to Pacwest Network,  Inc. ("PNI"), an entity that is controlled
by John Warta, the Company's  Chairman of the Board and Chief Executive Officer.
In addition,  under the FCC's foreign  ownership  rules, the Company cannot hold
Personal  Communications Services ("PCS") licenses. See "--Possible Inability to
Recover Payments Made to Magnacom." The FCC also has the authority,  which it is
not  presently  exercising,  to impose  restrictions  on  foreign  ownership  of
communications  service  providers not utilizing radio  frequencies (such as the
Company).  In the  event  the FCC  exercises  such  authority,  it could  have a
material  adverse  effect  on the  Company's  CLEC  and  other  businesses.  See
"Business -- Regulation."
    

NEED TO ADAPT TO TECHNOLOGICAL CHANGE

         The  telecommunications  industry  is subject to rapid and  significant
changes  in  technology,  with the  Company  relying  on third  parties  for the
development of and access to new technology. The effect of technological changes
on the business of the Company  cannot be  predicted.  The Company  believes its
future  success will depend,  in part,  on its ability to anticipate or adapt to
such  changes  and to offer,  on a timely  basis,  services  that meet  customer
demands.

         The future success of NACT will depend in part upon its ability to keep
pace  with  advancing   technology,   evolving  industry  standards  within  the
telecommunications   industry   and   changing   customer   requirements   in  a
cost-effective  manner.  There can be no assurance that NACT's products will not
be  rendered  obsolete  by  other   telecommunications   products  incorporating
technological   advances   designed  by  competitors  that  NACT  is  unable  to
incorporate into its products in a timely manner.

LITIGATION RISKS

         The  Company is involved in various  legal  proceedings.  An action was
commenced against NACT alleging that its telephone systems incorporating prepaid
debit card features infringe upon a patent issued in 1987. GST was

added as a defendant to such action in August 1997. An  unfavorable  decision in
such action could have a material  adverse  effect on the  Company.  Other legal
proceedings  that the  Company is a party to may have an effect on the  Company,
however,  at the present time the Company  does not believe that an  unfavorable
result in any of such  proceedings  will have a material  adverse  effect on the
Company. See "Business -- Legal Proceedings."

POSSIBLE INABILITY TO RECOVER PAYMENTS MADE TO MAGNACOM

         Magnacom  Wireless,  LLC  ("Magnacom"),  a company  controlled  by John
Warta,  the Company's  Chairman of the Board and Chief  Executive  Officer,  was
awarded  various PCS licenses.  Magnacom holds 30 MHz (C Block) PCS licenses for
five markets in Arizona,  New Mexico and Oregon and has acquired 10 MHz licenses
in the FCC's F Block in 13  markets  in Hawaii,  Idaho,  Oregon and  Washington.
Magnacom also has an application pending with the FCC for the assignment of 6 (C
Block) PCS licenses from an unaffiliated entity.

         Magnacom and the Company have entered into a 12-year reseller agreement
(the "Magnacom Reseller  Agreement")  pursuant to which (i) the Company has been
designated a non-exclusive  reseller of PCS telephone services in the markets in
which  Magnacom has obtained  licenses,  and (ii) Magnacom has agreed to use the
Company  on an  exclusive  basis to  provide  switched  local and long  distance
services and other enhanced  telecommunications  services,  to all of Magnacom's
resellers in markets where the Company has operational networks. Magnacom agreed
to sell PCS  minutes to the  Company  at $.05 per  minute,  subject to  downward
adjustment  to equal  the most  favorable  rates  offered  to  Magnacom's  other
resellers (but in no event less than  Magnacom's  cost).  In connection with the
Magnacom Reseller Agreement,  as of June 30, 1997, the Company had paid Magnacom
approximately $14.0 million as prepayments for future PCS services.

         In February  1997,  an  affiliate of Magnacom,  Guam Net,  Inc.  ("Guam
Net"), acquired from Poka Lambro Telephone Cooperative,  Inc. a 30 MHz (A Block)
PCS  license  from the FCC in the  market  consisting  of Guam and the  Northern
Mariana Islands.  Concurrently, the Company entered into a reseller agreement on
terms substantially similar to the Magnacom Reseller Agreement and paid Guam Net
$.4 million as a prepayment for future PCS services.

         The  provision of wireless  telecommunications  service by Magnacom and
Guam Net will be dependent upon their ability to obtain the financing  necessary
to make payments to the FCC under the terms of their licenses, to obtain working
capital  and to  build  the  required  facilities,  including  the  purchase  of
telecommunications  equipment.  There can be no assurance  that Magnacom or Guam
Net will  obtain such  financing  or be able to provide  PCS  services.  In such
event,  the Company  would  likely be unable to recover its payments to Magnacom
and Guam Net.
    

DEPENDENCE ON KEY PERSONNEL

         The efforts of a small number of key management and operating personnel
will largely determine the Company's success and the loss of any of such persons
could adversely  affect the Company.  The success of the Company also depends in
part upon its ability to hire and retain highly skilled and qualified operating,
marketing,  financial and technical  personnel.  The  competition  for qualified
personnel in the telecommunications industry is intense and, accordingly,  there
can be no assurance  that the Company  will be able to hire or retain  necessary
personnel.

DEPENDENCE ON RIGHTS-OF-WAY AND OTHER THIRD PARTY AGREEMENTS

         The   Company   must   obtain   easements,   rights-of-way,   entry  to
premises,franchises  and  licenses  from  various  private  parties,  actual and
potential  competitors and state and local governments in order to construct and
operate its  networks.  There can be no  assurance  that the Company will obtain
rights-of-way  and franchise  agreements on acceptable  terms or that current or
potential  competitors  will not  obtain  similar  rights-of-way  and  franchise
agreements  that will allow them to compete  against the Company.  If any of the
existing  franchise or license agreements were terminated or not renewed and the
Company were forced to remove its fiber optic cables or

                                      -25-

<PAGE>
abandon its networks in place,  such  termination  could have a material adverse
effect on the Company.See "Business -- Legal Proceedings" and "-- Regulation."

VARIABILITY OF QUARTERLY OPERATING RESULTS

         As a result of the limited revenues and significant expenses associated
with the expansion  and  development  of its networks and services,  the Company
anticipates that its operating results could vary  significantly  from period to
period. In addition,  revenues relating to the Company's network  businesses are
and may continue to be dependent upon a small number of customers and contracts,
revenues under which are likely to vary significantly from period to period.

RISK OF JOINT INVESTMENTS

         The  Company  has  invested  in one joint  venture  and may enter  into
additional  joint ventures in the future.  There are risks in  participating  in
joint ventures,  including the risk that the other joint venture partners may at
any  time  have  economic,  business  or  legal  interests  or  goals  that  are
inconsistent  with those of the joint  venture or the Company.  The risk is also
present that a joint venture partner may be unable to meet its economic or other
obligations to the joint venture and that the Company may be required to fulfill
some or all of those  obligations.  In addition,  to the extent that the Company
participates in  international  joint ventures,  the operations of such ventures
will be subject to  various  additional  risks not  present  in  domestic  joint
ventures,  such as fluctuations in currency  exchange  rates,nationalization  or
expropriation  of  assets,   import/export   controls,   political  instability,
limitations  on  foreign  investment,  restrictions  on the  ability  to convert
currencies  and  the  additional  expenses  and  risks  inherent  in  conducting
operations in geographically distant locations with customers speaking different
languages and having different cultural approaches to the conduct of business.

         As of June 30,  1997,  the  Company  had  invested  approximately  $3.7
million in a  publicly-traded  Canadian  corporation  (subsequently  renamed GST
Global  Telecommunications  Inc.,  "Global") and holds approximately 3.6 million
shares.  In addition,  the Company has warrants to purchase  750,000  additional
shares.  On  June  30,  1997,  Global  had  approximately  12.6  million  shares
outstanding.  Global  will  issue to the  Company  additional  common  shares of
Global,   subject  to  approval  of  the  Vancouver  Stock  Exchange  ("VSE"),in
consideration  for the transfer by the Company to Global of its rights in and to
a telecommunications  project in Mexico (the "Bestel Project").  Global has also
acquired from Cable and Wireless, Inc. ("Cable and Wireless") an 80% interest in
Vitacom  Corporation  ("Vitacom").  Vitacom  provides  voice,  high  speed  data
information  and other  services  and  manufactures  and sells VSATs (very small
aperture  satellite  terminals) and other equipment used to access the Internet.
See "Business -- GST Global Telecommunications Inc."

RISKS OF INVESTMENT IN A CANADIAN CORPORATION

   
         The Company is a Canadian  corporation.  Certain of its  directors  and
officers and certain of its  professionals are residents of Canada. As a result,
it may be difficult to effect  service of process  within the United States upon
such  directors,  officers  and  professionals  or to collect  judgments of U.S.
courts  predicated upon civil liability under U.S. federal  securities and other
laws. It is uncertain  whether  Canadian  courts would (i) enforce  judgments of
U.S.  courts  obtained  against  the  Company or such  directors,  officers  and
professionals  predicated upon the civil liabilities  provisions of U.S. laws or
(ii)  impose  liabilities  in  original  actions  against  the  Company  or  its
directors,  officers and  professionals  predicated  solely upon U.S.  laws.  In
addition,  the Company's  status as a Canadian company limits the ability of the
Company to hold or control radio frequency licenses in the United States.
    

FORWARD-LOOKING STATEMENTS AND ASSOCIATED RISKS

         This   Prospectus   contains    forward-looking    statements.    These
forward-looking  statements  reflect the Company's  views with respect to future
events and financial  performance.  Actual results could differ  materially from
those  projected  in the  forward-looking  statements  as a  result  of the risk
factors set forth above. The words,

                                      -26-

<PAGE>

"believe,"   "expect"  and   "anticipate"  and  similar   expressions   identify
forward-looking statements. Readers are cautioned not to place undue reliance on
these  forward-looking  statements,  which  speak  only as of their  dates.  The
Company   undertakes   no   obligations   to  publicly   update  or  revise  any
forward-looking statements, whether as a result of new information,future events
or otherwise.

EXCHANGE OF NOTES

         No gain or loss will be  recognized  by an  exchanging  Holder  upon an
exchange of the Old Notes for the New Notes.  A Holder's  basis in the New Notes
will be the  same as the  Holder's  basis  in the Old  Notes,  and the  Holder's
holding  period in the New Notes will  include the period  during  which the Old
Notes had been held by the Holder.  If the exchange of the Old Notes for the New
Notes were deemed by the Internal  Revenue Service (the "Service") to constitute
the  exchange  of a debt  instrument  for a modified  instrument  that  differed
materially either in kind or in extent, additional original issue discount could
arise.  However,  under the relevant  regulations issued by the Service, the New
Notes  should  not be deemed to  constitute  a  modification  of the Old  Notes,
inasmuch  as the New Notes  reflect all of the terms and  conditions  of the Old
Notes in registered form, which registration  results from the original terms of
the Old Notes.

LACK OF A PUBLIC MARKET

         The New  Notes  will  constitute  a new  issue  of  securities  with no
established  trading market. GST Funding is seeking to list the Old Notes on the
Luxembourg Stock Exchange.  GST Funding does not intend to list the New Notes on
any United States securities  exchange or to seek approval for quotation through
any automated  quotation  system.  GST Funding has been advised by the Placement
Agents that following  completion of the Exchange  Offer,  the Placement  Agents
intend to make a market in the New Notes.  However, the Placement Agents are not
obligated  to do so and any  market-making  activities  with  respect to the New
Notes may be discontinued at any time without notice.  Accordingly, no assurance
can be given that an active  public or other  market  will  develop  for the New
Notes or as to the  liquidity of or the trading  market for the New Notes.  If a
trading market does not develop or is not  maintained,  Holders of the New Notes
may  experience  difficulty  in reselling the New Notes or may be unable to sell
them at all. If a market for the New Notes  develops,  any such market may cease
to continue at any time. If a public trading market  develops for the New Notes,
future trading  prices of the New Notes will depend on many factors,  including,
among  other  things,  prevailing  interest  rates,  the  Company's  results  of
operations and the market for similar  securities  and other factors,  including
the financial condition of the Company.

CONSEQUENCES OF THE EXCHANGE OFFER TO NON-TENDERING HOLDERS OF THE OLD NOTES

         In the event the Exchange Offer is consummated, GST Funding will not be
required to register  any Old Notes not  tendered  and  accepted in the Exchange
Offer. In such event, Holders of Old Notes seeking liquidity in their investment
would have to rely on  exemptions  to the  registration  requirements  under the
Securities Act. Following the Exchange Offer, none of the Notes will be entitled
to the  contingent  increase in interest  rate  provided  for (in the event of a
failure to consummate  the Exchange  Offer in  accordance  with the terms of the
Registration Rights Agreement) pursuant to the Registration Rights Agreement.

   
POSSIBLE TREATMENT OF THE NOTES AS EQUITY

         Although  the  Company  believes  that the Notes  should be  treated as
indebtedness  for United  states  income tax  purposes,  it is possible that the
Notes may be treated as equity.  In the unlikely  event the Notes are treated as
equity, the amount of any actual or constructive  distributions on any such Note
would  first be taxable to the  holder as  dividend  income to the extent of the
issuer's current and accumulated earnings and profits, and next would be treated
as a return of capital to the extent of the holder's tax basis in the Note, with
any remaining amount treated as gain from the sale of a Note. As a result, until
such time as the issuer has earnings and profits as determined for United States
federal income tax purposes, distributions on any Note treated as equity will be
a  nontaxable  return of capital and will be applied  against and in the case of
actual distributions reduce the adjusted tax basis of such
    

                                      -27-

<PAGE>
   
Note in the hands of its holder (but not below zero).  Further,  payments on the
Notes treated as equity to Non-U.S.  Holders (as hereinafter  defined) would not
be eligible for the portfolio  interest exception from United States withholding
tax, and dividends thereon would be subject to United States  withholding tax at
a flat rate of 30% (or lower applicable treaty rate) and gain from their sale or
other  taxable  disposition  might  also be  subject to United  States  tax.  In
addition, in the event of equity treatment,  neither GST Funding nor GST USA, as
the case may be,  would ever be  entitled  to deduct  interest  on the Notes for
United States federal income tax purposes.

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

         The Old Notes were sold by GST Funding on May 13, 1997 to the Placement
Agents,  which  placed the Old Notes with  certain  institutional  investors  in
reliance  on Section  4(2) of,  and Rule 144A  under,  the  Securities  Act.  In
connection  with  the  sale of the Old  Notes,  GST  Funding  entered  into  the
Registration  Rights Agreement,  pursuant to which GST Funding,  GST USA and GST
agreed to use their best  efforts to  consummate  an offer to  exchange  the Old
Notes for the New Notes  pursuant to an effective  registration  statement on or
before November 13, 1997. A copy of the  Registration  Rights Agreement has been
filed as an exhibit to this Registration Statement.  Unless the context requires
otherwise, the term "Holder" with respect to the Exchange Offer means any person
in whose name Old Notes are  registered on the books of GST Funding or any other
person  who has  obtained a properly  completed  bond power from the  registered
Holder,  or any person  whose Old Notes are held of record by DTC who desires to
deliver such Old Notes by book-entry transfer at DTC.

         GST  Funding  has not  requested,  and does not intend to  request,  an
interpretation  by the staff of the  Commission  with respect to whether the New
Notes issued pursuant to the Exchange Offer in exchange for the Old Notes may be
offered  for  sale,  resold  or  otherwise  transferred  by any  Holder  without
compliance  with the  registration  and  prospectus  delivery  provisions of the
Securities  Act.  Based on  interpretations  by the staff of the  Commission set
forth in no-action  letters issued to third parties,  GST Funding  believes that
New Notes issued pursuant to the Exchange Offer in exchange for Old Notes may be
offered for resale,  resold and otherwise  transferred by any Holder of such New
Notes (other than any such Holder that is an "affiliate" of GST Funding, GST USA
or GST within the meaning of Rule 405 under the Securities Act and except in the
case  of  broker-dealers,  as set  forth  below)  without  compliance  with  the
registration and prospectus  delivery provisions of the Securities Act, provided
that  such New Notes  are  acquired  in the  ordinary  course  of such  Holder's
business and such Holder has no arrangement or understanding  with any person to
participate in the distribution of such New Notes. Any Holder who tenders in the
Exchange Offer for the purpose of  participating  in a  distribution  of the New
Notes or who is an affiliate of GST Funding, GST USA or GST may not rely on such
interpretation  by  the  staff  of the  Commission  and  must  comply  with  the
registration  and  prospectus  delivery  requirements  of the  Securities Act in
connection  with any  secondary  resale  transaction.  Each  broker-dealer  that
receives New Notes for its own account in exchange for Old Notes, where such Old
Notes  were  acquired  by  such  broker-dealer  as  a  result  of  market-making
activities or other trading activities,  must acknowledge that it will deliver a
prospectus  in  connection  with any  resale  of such New  Notes.  See  "Plan of
Distribution."

         By  tendering  in the  Exchange  Offer,  each  Holder of Old Notes will
represent to GST Funding,  GST USA and GST that, among other things, (i) the New
Notes acquired pursuant to the Exchange Offer are being obtained in the ordinary
course of business of the person  receiving such New Notes,  whether or not such
person is such Holder,  (ii) neither the Holder of Old Notes, nor any such other
person,  has an arrangement or  understanding  with any person to participate in
the distribution of such New Notes,  (iii) if the Holder is not a broker-dealer,
or is a  broker-dealer  but will not  receive  New Notes for its own  account in
exchange  for Old Notes,  neither  the  Holder,  nor any such other  person,  is
engaged in or intends to participate in the  distribution  of such New Notes and
(iv)  neither  the  Holder nor any such other  person is an  "affiliate"  of GST
Funding,  GST USA or GST within the meaning of Rule 405 under the Securities Act
or, if such  Holder is an  "affiliate,"  that such  Holder  will comply with the
registration and prospectus  delivery  requirements of the Securities Act to the
extent applicable.

         Following the consummation of the Exchange Offer,  Holders of Old Notes
not  tendered  will not have any further  registration  rights and the Old Notes
will continue to be subject to certain  restrictions  on transfer.  Accordingly,
the liquidity of the market for the Old Notes could be adversely affected.

TERMS OF THE EXCHANGE OFFER

         Upon  the  terms  and  subject  to the  conditions  set  forth  in this
Prospectus and in the Letter of Transmittal, GST Funding will accept any and all
Old Notes validly  tendered and not withdrawn  prior to 5:00 p.m., New York City
time, on the Expiration Date. Subject to the minimum  denomination  requirements
of the New Notes, GST Funding will issue $1,000 principal amount of New Notes in
exchange for each $1,000 principal amount of

                                      -29-

<PAGE>
outstanding Old Notes accepted in the Exchange Offer. Holders may tender some or
all of their Old Notes pursuant to the Exchange Offer. However, Old Notes may be
tendered only in integral multiples of $1,000 principal amount.

         The forms and terms of the New Notes will be  identical in all material
respects to the forms and terms of the corresponding Old Notes,  except that the
offer and sale of the New Notes will have been  registered  under the Securities
Act and, therefore, the New Notes will not bear legends restricting the transfer
thereof.  The  Exchange  Offer is not  conditioned  upon any  minimum  aggregate
principal amount of Old Notes being tendered for exchange.  As of June 30, 1997,
$265,000,000 aggregate principal amount of the Old Notes were outstanding.  This
Prospectus,  together  with the  Letter  of  Transmittal,  is being  sent to all
Holders as of ________,  1997. Holders of Old Notes do not have any appraisal or
dissenters'  rights under the Indenture in connection  with the Exchange  Offer.
GST  Funding  intends to  conduct  the  Exchange  Offer in  accordance  with the
applicable  requirements  of the  Exchange  Act and  the  applicable  rules  and
regulations of the Commission thereunder.

         GST Funding shall be deemed to have accepted validly tendered Old Notes
when,  as and if GST  Funding  has given oral or written  notice  thereof to the
Exchange Agent.  The Exchange Agent will act as agent for the tendering  Holders
for the purpose of receiving the New Notes from GST Funding. If any tendered Old
Notes are not accepted for exchange because of an invalid tender, the occurrence
of certain other events set forth herein or otherwise, such unaccepted Old Notes
will be returned,  without expense,  to the tendering Holder thereof as promptly
as practicable after the Expiration Date.

         Holders who tender Old Notes in the Exchange Offer will not be required
to pay brokerage  commissions  or fees or,  subject to the  instructions  in the
Letter of Transmittal,  transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange  Offer.  GST Funding will pay all charges and expenses,
other than certain  applicable taxes, in connection with the Exchange Offer. See
" -- Fees and Expenses."

EXPIRATION DATE; EXTENSIONS; AMENDMENTS

         The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
_____________,  1997, [20 BUSINESS DAYS AFTER THE  COMMENCEMENT  OF THE EXCHANGE
OFFER] unless GST Funding in its sole discretion, extends the Exchange Offer, in
which case the term  "Expiration  Date"  shall mean the latest  date and time to
which the  Exchange  Offer is  extended.  Although  GST  Funding  has no current
intention to extend the Exchange Offer, GST Funding reserves the right to extend
the  Exchange  Offer at any time and from time to time by giving oral or written
notice to the Exchange  Agent and by timely  public  announcement  communicated,
unless otherwise  required by applicable law or regulation,  by making a release
to the Dow Jones News Service.  During any extension of the Exchange Offer,  all
Old Notes previously  tendered  pursuant to the Exchange Offer and not withdrawn
will remain subject to the Exchange  Offer.  The date of the exchange of the New
Notes for Old Notes will be the first AMEX trading day following the  Expiration
Date.

         GST Funding expressly  reserves the right to (i) terminate the Exchange
Offer and not accept for  exchange  any Old Notes if any of the events set forth
below under " -- Conditions to the Exchange Offer" shall have occurred and shall
not have been  waived by GST  Funding  and (ii) amend the terms of the  Exchange
Offer in any manner that, in its good faith  judgment,  is  advantageous  to the
Holders of the Old Notes, whether before or after any tender of the Old Notes.

PROCEDURES FOR TENDERING

         The tender to GST Funding of Old Notes by a Holder thereof  pursuant to
one of the procedures set forth below will constitute an agreement  between such
Holder  and GST  Funding  in  accordance  with  the  terms  and  subject  to the
conditions  set forth  herein  and in the Letter of  Transmittal  signed by such
holder.  A Holder  of the Old Notes may  tender  such Old Notes by (i)  properly
completing  and  signing a Letter of  Transmittal  or a facsimile  thereof  (all
references  in this  Prospectus  to a Letter of  Transmittal  shall be deemed to
include  a  facsimile  thereof)  and  delivering  the  same,  together  with any
corresponding  certificate  or  certificates  representing  the Old Notes  being
tendered (if in certificated form) and any required signature guarantees, to the
Exchange Agent at its address set forth in the Letter of Transmittal on or prior
to the Expiration Date (or complying with the procedure for book-entry  transfer
described  below) or (ii)  complying  with the  guaranteed  delivery  procedures
described below.

                                      -30-

<PAGE>

         If tendered Old Notes are  registered  in the name of the signer of the
Letter of Transmittal and the New Notes to be issued in exchange therefor are to
be issued (and any  untendered  Old Notes are to be reissued) in the name of the
registered holder (which term, for the purposes described herein,  shall include
any participant in DTC whose name appears on a security  listing as the owner of
Old Notes),  the signature of such signer need not be  guaranteed.  In any other
case,  the  tendered  Old Notes  must be  endorsed  or  accompanied  by  written
instruments of transfer in form satisfactory to GST Funding and duly executed by
the  registered  Holder and the  signature on the  endorsement  or instrument of
transfer must be guaranteed by a member firm of a registered national securities
exchange  or  of  the  National  Association  of  Securities  Dealers,  Inc.,  a
commercial bank or trust company having an office or correspondent in the United
States or an "eligible  guarantor  institution" as defined by Rule 17Ad-15 under
the Exchange Act (any of the foregoing  hereinafter  referred to as an "Eligible
Institution").  If the New Notes  and/or the Old Notes not  exchanged  are to be
delivered to an address other than that of the  registered  Holder  appearing on
the register for the Old Notes,  the signature in the Letter of Transmittal must
be guaranteed by an Eligible Institution.

         THE METHOD OF  DELIVERY  OF OLD NOTES,  LETTER OF  TRANSMITTAL  AND ALL
OTHER  DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDER.  IF SUCH DELIVERY IS
BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL,  PROPERLY INSURED,  WITH RETURN
RECEIPT REQUESTED,  BE USED. IN ALL CASES,  SUFFICIENT TIME SHOULD BE ALLOWED TO
ASSURE TIMELY DELIVERY.  NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO
GST FUNDING.

         GST Funding  understands  that the  Exchange  Agent will make a request
promptly after the date of this  Prospectus to establish an account with respect
to the Old Notes at DTC for the purpose of facilitating  the Exchange Offer, and
subject  to the  establishment  thereof,  any  financial  institution  that is a
participant in DTC's system may make book-entry delivery of Old Notes by causing
DTC to transfer such Old Notes into the Exchange Agent's account with respect to
the Old Notes in accordance  with DTC's  procedure for such  transfer.  Although
delivery of the Old Notes may be effected through  book-entry  transfer into the
Exchange  Agent's account at DTC, an appropriate  Letter of Transmittal with any
required  signature  guarantee and all other revised documents must in each case
be transmitted to and received or confirmed by the Exchange Agent at the address
set forth in the Letter of Transmittal  on or prior to the Expiration  Date, or,
if the guaranteed delivery procedures  described below are complied with, within
the time period provided under such procedures.

         If the Holder  desires to accept the  Exchange  Offer and time will not
permit a Letter of  Transmittal  or Old Notes to reach the Exchange Agent before
the Expiration Date or the procedure for book-entry transfer cannot be completed
on a timely basis,  a tender may be effected if the Exchange  Agent has received
at its  office,  on or prior to the  Expiration  Date,  a  letter,  telegram  or
facsimile  transmission from an Eligible  Institution setting forth the name and
address  of the  tendering  Holder,  the  name(s)  in which  the Old  Notes  are
registered and the  certificate  number(s) of the Old Notes to be tendered,  and
stating  that the tender is being made  thereby and  guaranteeing  that,  within
three AMEX trading days after the date of execution of such letter,  telegram or
facsimile  transmission by the Eligible  Institution,  such Old Notes, in proper
form for transfer (or a  confirmation  of book-entry  transfer of such Old Notes
into the Exchange  Agent's  account at DTC),  will be delivered by such Eligible
Institution  together  with a properly  completed  and duly  executed  Letter of
Transmittal (and any other required documents).  Unless Old Notes being tendered
by the  above-described  method are deposited with the Exchange Agent within the
time period set forth  above  (accompanied  or preceded by a properly  completed
Letter of Transmittal and any other required documents), GST Funding may, at its
option, reject the tender. Copies of a Notice of Guaranteed Delivery,  which may
be used by Eligible  Institutions for the purposes  described in this paragraph,
are available from the Exchange Agent.

         A tender  will be deemed to have been  received as of the date when (i)
the tendering  Holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a confirmation  of book-entry  transfer of such
Old Notes into the Exchange Agent's account at DTC), is received by the Exchange
Agent or (ii) a Notice of Guaranteed  Delivery or letter,  telegram or facsimile
transmission to similar effect (as provided above) from an Eligible  Institution
is received by the  Exchange  Agent.  Issuances of New Notes in exchange for Old
Notes tendered pursuant to a Notice of Guaranteed  Delivery or letter,  telegram
or facsimile  transmission  to similar effect (as provided above) by an Eligible
Institution  will be made only  against  submission  of a duly signed  Letter of
Transmittal  (and any other required  documents) and deposit of the tendered Old
Notes.

                                      -31-

<PAGE>

         All questions as to the validity,  form, eligibility (including time of
receipt)  and  acceptance  for  exchange  of any  tender  of Old  Notes  will be
determined by GST Funding,  whose  determination will be final and binding.  GST
Funding  reserves the absolute  right to reject any or all tenders not in proper
form or the  acceptance  for  exchange  of  which  may,  in the  opinion  of GST
Funding's counsel, be unlawful.  GST Funding also reserves the absolute right to
waive any of the conditions of the Exchange Offer or any defect or  irregularity
in the tender of any Old Notes.  None of GST Funding,  the Exchange Agent or any
other  person  will be under any duty to give  notification  of any  defects  or
irregularities  in tenders or will incur any  liability  for failure to give any
such  notification.  Any Old Notes  received by the Exchange  Agent that are not
validly  tendered  and as to which the defects or  irregularities  have not been
cured or waived, or if Old Notes are submitted in an aggregate  principal amount
greater than the aggregate  principal amount of Old Notes being tendered by such
tendering  Holder,  will be  returned  by the  Exchange  Agent to the  tendering
holders,  unless  otherwise  provided in the Letter of  Transmittal,  as soon as
practicable following the Expiration Date.

         In addition,  GST Funding  reserves the right in its sole discretion to
(a) purchase or make offers for any Old Notes that remain outstanding subsequent
to the  Expiration  Date and (b) to the  extent  permitted  by  applicable  law,
purchase Old Notes in the open market, in privately  negotiated  transactions or
otherwise.  The terms of any such purchases or offers will differ from the terms
of the Exchange Offer.

TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL

         The Letter of Transmittal  contains,  among other things, the following
terms and conditions, which are part of the Exchange Offer.

         The  party   tendering  Old  Notes  for  exchange  (the   "Transferor")
exchanges,  assigns and transfers  the Old Notes to GST Funding and  irrevocably
constitutes  and  appoints  the  Exchange  Agent as the  Transferor's  agent and
attorney-in-fact  to  cause  the  Old  Notes  to be  assigned,  transferred  and
exchanged.  The  Transferor  represents  and warrants that it has full power and
authority to tender, exchange,  assign and transfer the Old Notes and to acquire
New Notes issuable upon the exchange of such tendered Old Notes,  and that, when
the  same  are  accepted  for  exchange,  GST  Funding  will  acquire  good  and
unencumbered  title to the  tendered  Old  Notes,  free and clear of all  liens,
restrictions, charges and encumbrances and not subject to any adverse claim. The
Transferor  also  warrants that it will,  upon request,  execute and deliver any
additional  documents  deemed by GST Funding to be  necessary  or  desirable  to
complete the exchange, assignment and transfer of tendered Old Notes or transfer
ownership  of such  Old  Notes  on the  account  books  maintained  by DTC.  All
authority  conferred by the  Transferor  will survive the death,  bankruptcy  or
incapacity of the  Transferor  and every  obligation of the  Transferor  will be
binding upon the heirs, legal representatives,  successors,  assigns,  executors
and administrators of such Transferor.

         By  executing  a Letter of  Transmittal,  each  Holder will make to GST
Funding, GST USA and GST the representations set forth above under the heading "
- -- Purpose and Effect of the Exchange Offer."

WITHDRAWAL OF TENDERS

         Tenders of Old Notes  pursuant to the Exchange  Offer are  irrevocable,
except that Old Notes  tendered  pursuant to the Exchange Offer may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration Date.

         To be  effective,  a written,  telegraphic  or  facsimile  transmission
notice  of  withdrawal  must be timely  received  by the  Exchange  Agent at the
address set forth in the Letter of Transmittal prior to 5:00 p.m., New York City
time on the  Expiration  Date.  Any such notice of  withdrawal  must specify the
holder  named in the Letter of  Transmittal  as having  tendered Old Notes to be
withdrawn, the certificate numbers and designation of Old Notes to be withdrawn,
the principal amount of Old Notes delivered for exchange,  a statement that such
Holder is  withdrawing  his election to have such Old Notes  exchanged,  and the
name of the  registered  Holder  of such Old  Notes,  and must be  signed by the
Holder in the same manner as the original signature on the Letter of Transmittal
(including  any required  signature  guarantees)  or be  accompanied by evidence
satisfactory to GST Funding that the person withdrawing the tender has succeeded
to the beneficial ownership of the Old Notes being withdrawn. The Exchange Agent
will return the  properly  withdrawn  Old Notes  promptly  following  receipt of
notice of withdrawal.

                                      -32-

<PAGE>
If Old  Notes  have been  tendered  pursuant  to the  procedure  for  book-entry
transfer,  any  notice of  withdrawal  must  specify  the name and number of the
account at DTC to be credited with the  withdrawn Old Notes or otherwise  comply
with DTC  procedure.  All questions as to the validity of notices of withdrawal,
including  time  of  receipt,  will  be  determined  by GST  Funding,  and  such
determination will be final and binding on all parties.

CONDITIONS TO THE EXCHANGE OFFER

         Notwithstanding  any other  provision  of the  Exchange  Offer,  or any
extension of the Exchange  Offer,  GST Funding will not be required to issue New
Notes in exchange for any properly  tendered Old Notes not theretofore  accepted
and may terminate  the Exchange  Offer,  or, at its option,  modify or otherwise
amend the Exchange Offer, if either of the following events occur:

   
         (a) any statute,  rule or regulation  shall have been  enacted,  or any
         action  shall  have been taken by any court or  governmental  authority
         which,  in the  reasonable  judgment of GST  Funding,  would  prohibit,
         restrict or  otherwise  render  illegal  consummation  of the  Exchange
         Offer, or

         (b) there  shall occur a change in the  current  interpretation  by the
         staff of the Commission  which, in GST Funding's  reasonable  judgment,
         might  materially  impair GST  Funding's  ability  to proceed  with the
         Exchange Offer.
    

         GST Funding  expressly  reserves  the right to  terminate  the Exchange
Offer and not accept for exchange any Old Notes upon the occurrence of either of
the foregoing  conditions (which represent all of the material conditions to the
acceptance by GST Funding of properly tendered Old Notes).

   
         The  foregoing  conditions  are for the sole benefit of GST Funding and
may be waived by GST Funding, in whole or in part, in its reasonable discretion.
The foregoing conditions must be either satisfied or waived prior to termination
of the Exchange  Offer.  Any  determination  made by GST Funding  concerning  an
event,  development or circumstance described or referred to above will be final
and binding on all parties.

FEES AND EXPENSES

         The expense of  soliciting  tenders will be borne by GST  Funding.  The
principal solicitation is being made by mail; however,  additional solicitations
may be made by  telegraph,  telephone  or in  person  by  officers  and  regular
employees of GST Funding and its affiliates.  No additional compensation will be
paid to any such officers and employees who engage in soliciting tenders.

         GST Funding has not retained  any  dealer-manager  or other  soliciting
agent in  connection  with the Exchange  Offer and will not make any payments to
brokers,  dealers or others  soliciting  acceptances of the Exchange Offer.  GST
Funding,  however, will pay the Exchange Agent reasonable and customary fees for
its services and will reimburse it for its reasonable  out-of-pocket expenses in
connection  therewith.  GST  Funding  may also pay  brokerage  houses  and other
custodians,  nominees and  fiduciaries  the  reasonable  out-of-pocket  expenses
incurred  by  them in  forwarding  copies  of this  Prospectus,  the  Letter  of
Transmittal and related  documents to the beneficial owners of the Old Notes and
in handling or forwarding tenders for exchange.

         The  expenses to be incurred in  connection  with the  Exchange  Offer,
including fees and expenses of the Exchange Agent and Trustee and accounting and
legal fees of GST Funding, will be paid by GST Funding.

         GST Funding  will pay all transfer  taxes,  if any,  applicable  to the
exchange of Old Notes pursuant to the Exchange Offer. If, however, New Notes, or
Old Notes for principal amounts not tendered or accepted for exchange, are to be
delivered  to, or are to be issued in the name of,  any  person  other  than the
registered  Holder of the Old Notes tendered or if a transfer tax is imposed for
any reason other than the exchange of Old Notes pursuant to the Exchange  Offer,
then the amount of any such transfer  taxes  (whether  imposed on the registered
Holder or any  other  persons)  will be  payable  by the  tendering  Holder.  If
satisfactory  evidence of payment of such taxes or  exemption  therefrom  is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering Holder.

ACCOUNTING TREATMENT

         The New Notes will be  recorded at the same  carrying  value as the Old
Notes  as  reflected  in GST  Funding's  accounting  records  on the date of the
exchange  because  the  exchange  of the Old  Notes  for the  New  Notes  is the
completion of the selling process contemplated in the issuance of the Old Notes.
Accordingly,  no gain or loss for accounting  purposes will be  recognized.  The
expenses  of the  Exchange  Offer and the  unamortized  expenses  related to the
issuance of the Old Notes will be amortized over the term of the New Notes.

OTHER

         Participation  in the Exchange  Offer is voluntary  and Holders  should
carefully  consider  whether  to  accept.  Holders of the Old Notes are urged to
consult  their  financial and tax advisors in making their own decisions on what
action to take.

         No person has been  authorized to give any  information  or to make any
representations in connection with the Exchange Offer other than those contained
in this Prospectus. If given or made, such information or representations should
not be relied upon as having been  authorized  by GST  Funding,  GST USA or GST.
Neither the delivery of this  Prospectus nor any exchange made hereunder  shall,
under any  circumstances,  shall create any  implication  that there has been no
change in the affairs of GST Funding,  GST USA or GST since the respective dates
as of which information is given herein. The Exchange Offer is not being made to
(nor will tenders be accepted  from or on behalf of) Holders of Old Notes in any
jurisdiction in which the making of the Exchange Offer or the acceptance thereof
would not be in  compliance  with the laws of such  jurisdiction.  However,  GST
Funding  may, at its  discretion,  take such action as it may deem  necessary to
make the Exchange Offer in any such  jurisdiction  and extend the Exchange Offer
to Holders of Old Notes in such jurisdiction.

         As a result of the making of the Exchange Offer,  GST Funding,  GST USA
and GST will have  fulfilled a covenant  contained  in the  Registration  Rights
Agreement.  Holders  of the Old Notes who do not  tender  their Old Notes in the
Exchange  Offer will continue to hold such Old Notes and will be entitled to all
the rights and

                                      -34-

<PAGE>
limitations  applicable  thereto under the Indenture  except for any such rights
under the  Registration  Rights Agreement and except that the Old Notes will not
be entitled to the contingent  increase in interest rate provided for in the Old
Notes.  All untendered Old Notes will continue to be subject to the restrictions
on transfer set forth in the Indenture and the Old Notes. To the extent that Old
Notes are tendered and accepted in the Exchange Offer,  the trading  market,  if
any, for untendered Old Notes could be adversely affected.

                                 USE OF PROCEEDS

         GST Funding will not receive any cash proceeds from the issuance of the
New  Notes  offered  hereby.  In  consideration  for  issuing  the New  Notes as
contemplated in this Prospectus,  GST Funding will receive in exchange Old Notes
in like  principal  amount,  the terms of which are  identical  in all  material
respects to the New Notes, except that the offer and sale of such New Notes will
be registered  under the  Securities Act and,  therefore,  will not bear legends
restricting  the transfer  thereof.  Old Notes  surrendered  in exchange for New
Notes will be retired and canceled and cannot be reissued. Accordingly, issuance
of the New Notes will not result in a change in the indebtedness of the Company.

         GST Funding  received  gross proceeds of  approximately  $265.0 million
from the May Offering.  Of the net proceeds of the May  Offering,  approximately
$93.8  million was used to  purchase  Pledged  Securities  to fund the first six
scheduled interest payments on the Notes,  approximately  $54.3 million was used
to purchase  Acquired  Equipment  ($41.5  million of which was used to refinance
intercompany  indebtedness) as of June 30, 1997, and the balance will be used to
finance  purchase and install  telecommunications  equipment such as fiber optic
cable, switches and other related equipment.

         of  accounting,  as the entities were under common  control  during the
         period.

(b)      Excludes  capitalized  interest  of $291 for  Fiscal  1995,  $2,316 for
         Fiscal  1996 and $1,706  for the nine  months  ended June 30,  1996 and
         $10,387  for  the  nine  months  ended  June  30,   1997.   During  the
         construction  of GST USA's  networks,  the  interest  costs  related to
         construction  expenditures  are considered to be assets  qualifying for
         interest  capitalization under FASB Statement No. 34 "Capitalization of
         Interest Cost."

(c)      During  Fiscal 1994 and the first eight months of Fiscal 1995,  GST USA
         owned less than 80% of GST Telecom and was  therefore  unable to deduct
         for tax purposes the losses incurred by GST Telecom.

(d)      Includes minority interest in (income) loss of subsidiaries of (i) ($2)
         for Fiscal  1994,  (ii) $2,364 for Fiscal  1995,  (iii) $411 for Fiscal
         1996,  (iv) $335 for the nine months ended June 30, 1996 and (v) ($391)
         for the nine months ended June 30, 1997.

(e)      The ratio of earnings to fixed  charges is computed by dividing  pretax
         income from  continuing  operations  before fixed  charges  (other than
         capitalized  interest)  by fixed  charges.  Fixed  charges  consist  of
         interest  charges and  amortization  of debt  expense  and  discount or
         premium related to  indebtedness,  whether  expensed or capitalized and
         that   portion  of  rental   expense   the   Company   believes  to  be
         representative of interest.  For Fiscal 1994, Fiscal 1995, Fiscal 1996,
         the nine months  ended June 30, 1996 and the nine months ended June 30,
         1997,  earnings  were  insufficient  to  cover  fixed  charges  by $2.8
         million, $11.9 million, $57.8 million, $36.1 million and $68.8 million,
         respectively.

(f)      EBITDA consists of loss before interest, income taxes, depreciation and
         amortization  and other income and expense.  EBITDA is provided because
         it is a measure  commonly  used in the  industry.  It is  presented  to
         enhance an  understanding  of GST USA's  operating  results  and is not
         intended to represent  cash flow or results of operations in accordance
         with  generally   accepted   accounting   principles  for  the  periods
         indicated.  See GST USA's consolidated  financial  statements and notes
         thereto included elsewhere in this Prospectus.

(g)      Represents principally GST USA's then 50% ownership interest in Phoenix
         Fiber, the owner and operator of the Phoenix network.  GST USA acquired
         the remaining 50% interest in Phoenix Fiber  effective as of October 1,
         1996.

(b)      The Company  changed its fiscal year end to September 30,  effective in
         1994.  As a result,  amounts  reported  for Fiscal  1994 are for the 13
         months ended  September  30, 1994.  Results for Fiscal 1994 include the
         acquisition of 60% of GST Telecom,  the Company's  subsidiary that owns
         and operates  each of the  Company's  networks,  and, at various  times
         during fiscal 1994, an aggregate of 80% of NACT.

(c)      Excludes  capitalized  interest  of $291 for  Fiscal  1995,  $2,316 for
         Fiscal  1996 and $1,706  for the nine  months  ended June 30,  1996 and
         $10,387  for  the  nine  months  ended  June  30,   1997.   During  the
         construction of the Company's  networks,  the interest costs related to
         construction  expenditures  are considered to be assets  qualifying for
         interest  capitalization under FASB Statement No. 34 "Capitalization of
         Interest Cost."

(d)      During  Fiscal  1994 and the first  eight  months of Fiscal  1995,  the
         Company owned less than 80% of GST Telecom and was therefore  unable to
         deduct for tax purposes the losses incurred by GST Telecom.

(e)      Includes minority interest in (income) loss of subsidiaries of (i) ($2)
         for Fiscal  1994,  (ii) $2,364 for Fiscal  1995,  (iii) $411 for Fiscal
         1996,  (iv) $335 for the nine months ended June 30, 1996 and (v) ($391)
         for the nine months ended June 30, 1997.

(f)      Includes $202 loss from discontinued operations.

(g)      The ratio of earnings to fixed  charges is computed by dividing  pretax
         income from  continuing  operations  before fixed  charges  (other than
         capitalized  interest)  by fixed  charges.  Fixed  charges  consist  of
         interest  charges and  amortization  of debt  expense  and  discount or
         premium related to  indebtedness,  whether  expensed or capitalized and
         that   portion  of  rental   expense   the   Company   believes  to  be
         representative of interest.  For Fiscal 1993, Fiscal 1994, Fiscal 1995,
         Fiscal  1996,  the nine months  ended June 30, 1996 and the nine months
         ended June 30, 1997,  earnings were insufficient to cover fixed charges
         by $.8 million,  $3.0 million,  $13.8  million,  $62.9  million,  $39.1
         million and $76.5 million, respectively.

(h)      EBITDA consists of loss before interest, income taxes, depreciation and
         amortization  and other income and expense.  EBITDA is provided because
         it is a measure  commonly  used in the  industry.  It is  presented  to
         enhance an understanding of the Company's  operating results and is not
         intended to represent  cash flow or results of operations in accordance
         with  generally   accepted   accounting   principles  for  the  periods
         indicated.  See the Company's  consolidated  financial  statements  and
         notes thereto included elsewhere in this Prospectus.

(i)      Represents  principally  the Company's  then 50% ownership  interest in
         Phoenix  Fiber,  the owner and  operator  of the Phoenix  network.  The
         Company  acquired the remaining 50% interest in Phoenix Fiber effective
         as of October 1, 1996.

(j)      At June 30, 1997, the Company was committed to issue the following: (i)
         a minimum  of  174,906  Common  Shares to the  former  shareholders  of
         TotalNet  in  October  1997 and (ii) a number of Common  Shares  with a
         market  value of $1.2  million,  based on the then market  value of the
         Common  Shares and  payable at various  times in Fiscal 1997 and Fiscal
         1998, to the former shareholders of Tri-Star.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

                                   GST FUNDING

OVERVIEW

         GST  Funding was formed on March 5, 1997 for the purpose of issuing the
Old Notes and financing the purchase of Acquired Equipment.  GST Funding acts as
purchasing  agent for GST USA and sells to GST USA the  equipment  it  purchases
with the  proceeds  from  the May  Offering.  GST  Funding  has  only a  limited
operating history.

         As of June 30,  1997,  GST Funding has  purchased  approximately  $54.3
million of equipment and holds  restricted cash and investments of approximately
$204.8 million  restricted  for the  acquisition of equipment and the payment of
interest.  All of such  equipment  has  been  sold to GST  USA in  exchange  for
Intercompany  Notes.  Ultimately,  such  equipment  is  leased by GST USA to the
various operating subsidiaries of the Company.

OPERATIONS

         The operations of GST Funding are limited to (i) purchasing  equipment,
(ii) selling equipment,  (iii) receiving payments under Intercompany Notes, (iv)
making  payments of interest and principal on the Notes,  and (v) fulfilling its
obligations  under the  Indenture,  the Pledge  Agreement  and the  Registration
Rights Agreement.

LIQUIDITY AND CAPITAL RESOURCES

         On May 13, 1997, GST Funding completed the May Offering,  consisting of
$265.0 million in Notes. Of the $255.8 million of net proceeds from the issuance
of the  Notes,  as of June 30,  1997  approximately  $93.8  million  was used to
purchase Pledged Securities to fund the first six interest payments on the Notes
and approximately  $54.3 million was used to purchase Acquired  Equipment ($41.5
million of which was used to refinance intercompany indebtedness). The Indenture
governing the Notes includes  restrictive  covenants  which,  among other items,
limit or restrict additional indebtedness incurred by the Company, investment in
certain subsidiaries and the payment of dividends.

                                     GST USA

         Since  inception in 1994 until the fourth  quarter of Fiscal 1996,  GST
USA held all of the Company's  consolidated operating subsidiaries and, as such,
GST USA's consolidated results of operations for those periods are substantially
similar to the  Company's.  The Company  directly  acquired GST Call America and
TotalNet in the fourth  quarter of Fiscal  1996 and Action  Telcom in the second
quarter of Fiscal 1997. The Company  anticipates that such  subsidiaries will be
transferred to GST USA within 12 months.

         The  analysis  of  GST  USA's  results  of  operations  is  based  on a
comparison of such results to the Company's  for the periods  presented,  and is
provided so that the reader may understand any significant difference.

         The  following  chart  details the  differences  in  operating  results
between the Company and GST USA. Such  differences  were computed by subtracting
the GST USA results from the Company's results for the measures provided.

         Revenues:  The  differences  in  revenues  for Fiscal 1996 and the nine
months ended June 30, 1997 result from the direct  acquisitions  of Call America
and TotalNet, and to a lesser extent, the direct acquisition of Action Telcom.

         Operating  expenses:  The differences in operating  expenses for Fiscal
1994,  Fiscal  1995 and the  nine  months  ended  June 30,  1996  relate  to the
custodial  expenses of the Company,  including legal and regulatory fees and the
salaries of certain  administrative  personnel.  The  differences  in  operating
expenses  for Fiscal 1996 and the nine months  ended June 30, 1997 relate to the
operating costs of the directly-held subsidiaries, including the amortization of
purchased intangibles, and to the aforementioned custodial expenses.

         Other  expenses:  The  difference in other income  (expense) for Fiscal
1994 is due to interest  income earned  directly by the Company.  The difference
for Fiscal 1995 relates primarily to losses on directly-held equity investments.
For Fiscal 1996 and the nine month  periods  ended June 30,  1996 and 1997,  the
primary  difference in other income  (expense) relate to interest expense on the
convertible  notes issued in December 1995.  Such notes are held directly by the
Company.

                                   THE COMPANY

OVERVIEW

   
         The  Company  provides a broad range of  integrated  telecommunications
products and services, primarily to customers located in the western continental
United States and Hawaii.  The Company's digital networks currently serve cities
in Arizona,  California,  Hawaii, New Mexico, Texas and Washington. In addition,
the Company has networks under  construction  which, when completed,  will serve
additional  cities and expand its  regional  footprint  to Oregon.  The  Company
provides,  through its established sales channels,  telecommunications  services
that include long distance, Internet and data transmission services and recently
introduced local dial tone services. In addition,  the Company produces advanced
telecommunications switching platforms with integrated applications software and
network telemanagement capabilities.
    

         The Company has invested  significant  capital and effort in developing
its  telecommunications   business.  This  capital  has  been  invested  in  the
development  of the Company's  networks,  for the hiring and  development  of an
experienced  management  team, the  development  and  installation  of operating
systems,  the  introduction  of services,  marketing  and sales  efforts and for
acquisitions. The Company expects to make increasing capital expenditures to

                                      -42-

<PAGE>
expand and interconnect  its networks and broaden its service  offerings and may
consummate  additional  acquisitions.  Proper management of the Company's growth
will  require the Company to maintain  quality  control over its services and to
expand the Company's internal management,  technical and accounting systems, all
of which will require substantial  investment.  See "Risk Factors -- Development
and Expansion  Risk and Possible  Inability to Manage  Growth," "--  Significant
Capital  Requirements,"  "--  Dependence  on  Billing,   Customer  Services  and
Information Systems" and "-- Liquidity and Capital Resources."

         Effective in 1994, the Company changed its fiscal year end to September
30,  in  order  to  conform  more  closely  to  the  reporting  periods  of  its
subsidiaries.  As a result of the  limited  revenues  and  significant  expenses
associated with the expansion and development of its networks and services,  the
Company's  operating results could vary significantly from period to period. See
"Risk Factors -- Variability of Quarterly Operating Results."

         NETWORK OPERATIONS. The development,  construction and expansion of the
Company's  network business  requires  significant  capital,  a large portion of
which is  invested  before  any  revenue  is  generated.  See "Risk  Factors  --
Significant Capital  Requirements." The Company has experienced,  and expects to
continue to experience,  increasing  negative EBITDA and losses while it expands
its  network  operations  and builds its  customer  base.  See "Risk  Factors --
Historical and Anticipated Future Operating Losses and Negative EBITDA." None of
the Company's existing networks is generating EBITDA. Based on its experience to
date and that of its competitors,  the Company estimates that a new network will
generate  EBITDA  within  30 to  36  months  after  commencement  of  commercial
operations. Construction periods and operating results will vary from network to
network.  There can be no assurance that the Company will be able to establish a
sufficient  revenue-generating customer base or achieve EBITDA in any particular
market or on a consolidated basis.

         Management  estimates that the total costs associated with the purchase
and  installation  of fiber optic cable and high-speed  electronic  transmission
equipment,  including  capitalized  engineering  costs,  will  range  from $10.0
million to $25.0  million  per  network,  depending  upon the size of the market
served  and the scope  and  complexity  of the  network.  Actual  costs may vary
significantly  from this range. The amounts and timing of these expenditures are
subject to a variety of factors that may vary  significantly  by the  geographic
and  demographic   characteristics  of  each  market.  In  addition  to  capital
expenditure  requirements,  upon  commencement  of the  construction  phase of a
network,  the Company begins to incur direct  operating  costs for such items as
salaries  and rent.  As network  construction  progresses,  the  Company  incurs
rights-of-way costs and increased sales and marketing  expenses.  Certain direct
preoperating  costs for new networks are  capitalized  until the network becomes
operational and are thereafter expensed as incurred.

         The  initial  development  of a network may take as long as six months,
depending  upon the size and complexity of the network and a variety of factors,
including  the time  required  to obtain  rights-of-way  and other  governmental
approvals, such as franchise agreements.  Once actual construction commences, it
may take from two to six months to complete  the initial  backbone  segment of a
network.  The time  required  during  the  construction  phase is  significantly
influenced  by the  number of route  miles  involved,  the mix of aerial  versus
underground  fiber  deployment,  possible delays in receiving fiber optic cable,
electronic equipment and required permits and other factors.

         LOCAL  SERVICES.  The Company  plans to  continue to install  switching
equipment  in its  operational  networks,  in markets  where it is  constructing
networks  and in  certain  other  cities  where  the  Company  will rely on ILEC
facilities for transmission,  as demand warrants.  Once a switch is operational,
where  regulatory  conditions  permit,  the Company  intends to offer local dial
tone,  in addition to enhanced  services such as ISDN,  Centrex,  voice mail and
other custom calling features.

         The Company expects  negative EBITDA from its switched  services during
the 24 to 36 month period after a switch is deployed.  For switches operating in
conjunction with the Company's  networks,  the Company expects operating margins
to improve as the network is expanded and larger  volumes of traffic are carried
on the Company's

                                      -43-

<PAGE>

network.  Until such time,  the Company will rely on the ILEC to  originate  and
terminate a significant  portion of its switched services traffic.  For switches
operating  in  cities  where  the  Company  will  rely  on ILEC  facilities  for
transmission,  the Company will experience lower or negative  operating  margins
under current ILEC pricing tariffs.  Although under the  Telecommunications  Act
the ILECs will be required to unbundle local tariffs,  permitting the Company to
purchase  only the  origination  and  termination  services  it  needs,  thereby
decreasing  operating  expenses,  there can be no assurance that such unbundling
will be  effected  in a timely  manner  and  result in prices  favorable  to the
Company.  See "Risk Factors -- Difficulties  in Implementing  Local and Enhanced
Services."

         LONG  DISTANCE  SERVICES.  The Company  offers basic and enhanced  long
distance  services,  such as toll free,  calling card,  prepaid calling card and
international  call  back  services,   targeting  primarily  business  customers
purchasing  between  $200 and $15,000 of services per month as well as resellers
and other carriers.  As part of the Company's strategy to become a provider of a
full range of  telecommunications  services and to offer total  solutions to its
customer base, in May 1995, the Company  acquired  International  Telemanagement
Group, Inc. ("ITG"), an international and domestic long distance carrier. During
Fiscal  1994,  NACT began  offering  wholesale  carrier and other  services  and
Wasatch   International   Network  Services,   Inc.   ("WINS"),   the  Company's
wholly-owned subsidiary,  began to offer enhanced long distance services. In the
second  half of 1996,  the  Company  expanded  its long  distance  products  and
services through the acquisitions of Action Telcom,  GST Call America,  TotalNet
and the  business of  Texas-Ohio.  The Company  provides  services as a reseller
under  agreements  with certain  major long  distance  carriers that provide the
Company  with  access to the  carriers'  networks  at rates  that are  typically
discounted,  varying with monthly traffic  generated by the Company through each
carrier's  network.  The Company is obligated to satisfy certain minimum monthly
usage requirements  through each network of $5.2 million per month over the next
three years. If such requirements are not satisfied,  the Company is required to
pay an  underutilization  fee in addition to its monthly bill. See "Risk Factors
- -- Risks Relating to Long Distance Business."

         INTERNET SERVICES.  In March 1996, the Company acquired the business of
Hawaii On Line, the largest  Internet access provider in Hawaii.  The Company is
also  presently  providing  Internet  services  to  customers  in  Portland  and
Vancouver  (Washington).  In addition to providing  Internet access, the Company
presently  offers  Internet-related  services such as Web site  development  and
hosting,  provides  EDI  services  and is in the process of  developing  various
Internet  software  applications.  Management  believes that these services will
become an important  component of the Company's  overall  product  offerings and
intends to continue to expand its Internet access and service  business to other
markets.

         DATA SERVICES.  The Company  offers  national and  international  frame
relay  services  on its own frame relay  network and through an  interconnection
agreement with Intermedia. Under this agreement, the Company and Intermedia have
agreed to link their data  networks and terminate  one  another's  traffic.  The
Company  plans to offer  additional  services  including  ATM,  high  speed  LAN
connectivity,  video  conferencing,  multimedia  networking and other  bandwidth
intensive applications.

         MANUFACTURING.  In September 1993, the Company purchased a 52% interest
in NACT, which produces  advanced  telecommunications  switching  platforms with
integrated applications software and network telemanagement capabilities. During
Fiscal 1994, the Company  acquired in a series of transactions an additional 28%
interest  in  NACT.  The  aggregate  consideration  paid for the  Company's  80%
interest  in NACT was  $5.7  million,  consisting  of $3.1  million  in cash and
451,536 Common Shares.  On January 5, 1995, the Company  purchased the remaining
20%  interest in NACT for  consideration  consisting  of $.8 million in cash and
notes payable and 504,747  Common  Shares.  In the third quarter of Fiscal 1996,
NACT  introduced  the STX, the first of a new  generation of switches,  which is
expected to be attractive to a broader group of customers. In the NACT Offering,
the Company and NACT sold one million and two million shares,  respectively,  of
NACT's  common  stock,  resulting  in gross  proceeds to the Company and NACT of
$10.0 million and $20.0 million, respectively. As a result of the NACT Offering,
the Company's interest in NACT has been reduced to approximately 63%.

RESULTS OF OPERATIONS

                    NINE MONTHS ENDED JUNE 30, 1997 COMPARED
                       TO NINE MONTHS ENDED JUNE 30, 1996

         REVENUES.  Total  revenues for the three and nine month  periods  ended
June 30, 1997 increased $16.7 million,  or 160.7%, and $49.7 million, or 197.0%,
respectively,  over the  comparable  three and nine month periods ended June 30,
1996.  Telecommunications services revenues for the three and nine month periods
ended June 30, 1997 increased $12.8 million,  or 161.2%,  and $39.3 million,  or
202.0%,  respectively,  over the  comparable  periods in the previous  year. The
increase in telecommunications  services revenues resulted from the inclusion of
revenues from strategic  acquisitions,  including GST Call America and TotalNet,
as well as increased CLEC service revenues generated by the Company's  networks.
To a  lesser  extent,  the  increase  in  telecommunications  services  revenues
resulted   from   increased   Internet,   shared   tenant  and  data   services.
Telecommunications  products revenues for the three and nine month periods ended
June 30, 1997 increased $3.9 million,  or 159.1%, and $10.4 million,  or 180.4%,
respectively,  over the three and nine months ended June 30, 1996.  The increase
in telecommunication  products revenues resulted primarily from the introduction
in April 1996 of NACT's STX switch and  subsequent  increased  unit sales.  To a
lesser extent the increase in product  revenues is due to the inclusion of newly
acquired  Action  Telcom's  sales of  network  management  and fraud  protection
systems.

         OPERATING  EXPENSES.  Total  operating  expenses for the three and nine
month periods ended June 30, 1997 increased $24.9 million,  or 117.8%, and $79.1
million,  or 156.6%,  respectively,  over the three and nine month periods ended
June 30, 1996.  Network  expenses,  which include direct local and long distance
circuit  costs,  were  75.4%  and  82.1%,  respectively,  of  telecommunications
services  revenues  for the three and nine month  periods  ended June 30,  1997,
compared to 63.7% and 76.7% for the  comparable  periods in the  previous  year.
Facilities  administration  and maintenance  expenses  (consisting  primarily of
costs  related to personnel  providing  maintenance,  monitoring  and  technical
assistance  for the  Company's  networks)  for the three and nine month  periods
ended June 30, 1997 were 16.4% and 16.7%,  respectively,  of  telecommunications
services revenues  compared to 45.2% and 29.8% for the comparable  periods ended
June 30,  1996.  The primary  reason for the  increase in network  expenses as a
percent of  telecommunications  services revenues and the decrease in facilities
administration  and  maintenance  expenses  as a percent  of  telecommunications
services revenues is the inclusion of revenue from 1996 strategic  acquisitions,
a significant  portion of which are generated from the resale of other carriers'
networks.

         Cost of product  revenues,  which  includes the costs  associated  with
product   revenues  of  NACT  and  Action  Telcom,   were  29.6%  and  34.3%  of
telecommunications  products revenues for the three and nine month periods ended
June 30,  1997,  respectively,  compared  to 46.4% and 48.6% for the  comparable
periods ended June 30, 1996.  The decrease  results  primarily from economies of
scale  related  to  increased  unit  sales of NACT's STX  switch.  Research  and
development  costs for the three and nine months  ended June 30, 1997  increased
$.4 million and $.8 million,  respectively,  over the comparable  periods in the
previous  year.  The increase is due to the addition of personnel to enhance the
current switch  product line and to facilitate the  development of new switching
products and applications.

         Selling,  general and  administrative  expenses  for the three and nine
month periods ended June 30, 1997 increased $9.8 million,  or 109.8%,  and $28.7
million, or 138.8%, respectively,  over the three and nine months ended June 30,
1996.  The increase is due to the expansion of the  Company's  CLEC and enhanced
services  operations,  and to the acquisition of four companies over the past 12
months.  The  implementation of the Company's  integrated  services strategy has
resulted in additional marketing, management information and sales staff.

         Depreciation  and  amortization  for the three and nine  month  periods
ended June 30, 1997 increased $3.6 million and $9.5 million, respectively,  over
the comparable  periods in the previous year.  The increase is  attributable  to
newly-constructed  networks  becoming  operational  and to the  amortization  of
intangible assets related

                                      -45-

<PAGE>

to the  Company's  acquisitions.  The Company  expects  that  depreciation  will
continue to increase as it expands its networks and increases switched services.

         OTHER  EXPENSES/INCOME.  For the three and nine  months  ended June 30,
1997, the Company  recorded net other expense of $8.8 million and $11.4 million,
respectively,  compared to net other  expense of $5.9 million and $12.1  million
for the comparable  periods ended June 30, 1996. For the nine month period,  the
reason for the  improvement  in net other  expenses as compared to the  previous
year  was a $7.4  million  gain  recognized  on the sale of one  million  of the
Company's shares of NACT in February 1997. If the gain had been excluded,  other
expenses for the nine month period ended June 30, 1997 would have increased $6.7
million over the nine month period ended June 30, 1996. Such increase  primarily
resulted from increased  interest expense due to the issuance of $180 million of
1995 Notes in December 1995 and the issuance of $265 million of Old Notes in May
1997. For the three month period,  the increase in other expenses as compared to
the same period of the previous year is primarily due to the interest related to
the May Offering.

                       FISCAL 1996 COMPARED TO FISCAL 1995

         REVENUES.  Total revenues for Fiscal 1996 increased  $22.6 million,  or
121.0%, to $41.3 million from $18.7 million for Fiscal 1995.  Telecommunications
services  revenues for Fiscal 1996 increased  $20.6  million,  or 185%, to $31.7
million from $11.1 million for Fiscal 1995.  The increase in  telecommunications
services   revenues  resulted  from  the  continuing  growth  of  long  distance
(including revenues  associated with Fiscal 1995 and 1996 acquisitions),  local,
Internet and data services.  Acquisitions  (primarily the acquisition of ITG but
also the  acquisitions  of GST Call America and the businesses of Hawaii On Line
and  Texas-Ohio)  accounted for $15.1 million of the increase in such  revenues.
See  "Business  --   Telecommunications   Services  Strategy  --  Long  Distance
Services."  Telecommunications  products revenues for Fiscal 1996 increased $2.0
million, or 26.6% over Fiscal 1995. The increase in telecommunications  products
revenues  resulted from the  introduction by NACT of the STX product line in the
third quarter of Fiscal 1996.

         OPERATING EXPENSES.  Total operating expenses for Fiscal 1996 increased
$53.6 million,  or 176.8%,  to $83.9 million from $30.3 million for Fiscal 1995.
Network  expenses,  which include direct local and long distance  circuit costs,
increased $16.5 million to $26.6 million from $10.1 million for Fiscal 1995, due
to  an  expanded   customer  base  and  increased  usage.  As  a  percentage  of
telecommunications  services revenues, network expenses decreased from 90.9% for
Fiscal 1995 to 83.8% for Fiscal 1996. Facilities  administration and maintenance
expenses  for Fiscal 1996  increased  $8.2  million to $10.3  million  from $2.1
million  for  Fiscal  1995.  As  a  percentage  of  telecommunications  services
revenues,  facilities  administration  and maintenance  expenses  increased from
18.9%  for  Fiscal  1995 to 32.5% for  Fiscal  1996.  The  increase  related  to
additional   personnel  and  facility  costs  required  by  continuing   network
expansion, a substantial portion of which are incurred before the realization of
revenues.

         Cost of product  revenues at NACT for Fiscal 1996 increased $.9 million
to  $4.0  million  from  $3.1  million  for  Fiscal  1995.  As a  percentage  of
telecommunications  products  revenues for Fiscal 1996, cost of product revenues
increased  nominally  as compared to Fiscal  1995 due to initial  lower  margins
resulting  from the  discontinuance  of NACT's former switch  product line as it
began to offer the new STX to existing customers. Research and development costs
increased nominally for Fiscal 1996 relative to Fiscal 1995 as the Company moved
to more  rapidly  develop an  improved  billing  system  product and to maintain
ongoing research and development of the Company's existing hardware and software
product lines.

         Selling,  general and administrative  expenses increased $22.0 million,
or 193.5%, to $33.4 million from $11.4 million for Fiscal 1995. The increase was
due to the expansion of the Company's CLEC and enhanced services operations, and
to a lesser extent, the acquisitions  during Fiscal 1996 of GST Call America and
Tri-Star and the businesses of Hawaii On Line and Texas-Ohio. The implementation
of the  Company's  integrated  services  strategy  has  resulted  in  additional
marketing, management information and sales staff.


                                      -46-

<PAGE>
         Depreciation and amortization for Fiscal 1996 increased $5.9 million to
$8.3 million  from $2.4  million for Fiscal 1995 due to  increased  depreciation
resulting from newly  constructed  networks  becoming  operational.  To a lesser
extent,  the increase in depreciation and amortization was also due to increased
amortization of intangible assets resulting from acquisitions.

         OTHER EXPENSES.  Other expenses for Fiscal 1996 increased $16.1 million
to $18.0 million from $1.9 million for Fiscal 1995. The increase was principally
the result of additional interest expense associated with the 1995 Notes, offset
by interest  income  resulting  from the  investment of the proceeds of the 1995
Notes Offering.

                       FISCAL 1995 COMPARED TO FISCAL 1994

         REVENUES.  Revenues for Fiscal 1995 increased $12.7 million, or 211.3%,
to $18.7 million from $6.0 million for Fiscal 1994. The increase resulted from a
$11.0  million  increase  in  telecommunications  services  revenues  and a $1.7
million,  or 28.4%,  increase in product  revenues  of NACT.  Telecommunications
service  revenues  increased  $10.6  million  as a result of  wholesale  carrier
services revenues generated by WINS and NACT, which began to offer such services
during Fiscal 1995,  and long distance and other service  revenues of ITG, which
was acquired effective May 1, 1995. In addition,  an increase of $.4 million was
the result of revenues  generated  by the  Hawaiian  digital  microwave  and the
Southern   California   networks.   The  Southern   California  networks  became
operational  in Fiscal 1995. The increase in  manufacturing  revenues was due to
increased unit sales of telecommunications  switching and network management and
billing systems.

         OPERATING EXPENSES.  Total operating expenses for Fiscal 1995 increased
$23.0  million,  or 315.0%,  to $30.3 million from $7.3 million for Fiscal 1994.
Network  expenses for Fiscal 1995 increased  $10.0 million to $10.1 million from
$.1  million  for  Fiscal  1994 due to  expansion  of  network  operations,  the
acquisition of ITG and the  commencement of wholesale  carrier  services at WINS
and NACT.  Facilities  administration  and  maintenance  expenses  totaled  $2.1
million for Fiscal 1995,  compared to only $26,000 for Fiscal 1994. The increase
was due to  significant  network  expansion in Fiscal 1995,  whereas Fiscal 1994
results  included  only three months of  engineering  expenses at the  Company's
Hawaiian network.

         Cost of product  revenues  at NACT for Fiscal  1995  increased  to $3.1
million,  or 40.9% of product  revenues,  for Fiscal 1995 from $2.1 million,  or
36.3%  of  product   revenues,   for  Fiscal  1994.   Research  and  development
expenditures  of NACT  increased  by $.6  million,  or 84.4% to $1.3 million for
Fiscal 1995 from $.7 million for Fiscal 1994 due to the  continuing  development
of the STX, which was introduced in Fiscal 1996.

         Selling,  general and administrative expenses increased $7.4 million to
$11.4  million for Fiscal 1995 from $4.0 million for Fiscal  1994.  The increase
was principally the result of higher salary and benefit costs incurred in Fiscal
1995  as the  Company  added  a  significant  number  of  sales,  marketing  and
management employees in connection with network expansion.  Also contributing to
the  increase  in  selling,  general  and  administrative  expenses  were higher
professional  fees and travel costs related to expansion of CLEC operations.  In
addition, bad debt expense increased $1.3 million in Fiscal 1995 principally due
to a reserve for doubtful accounts for an ITG customer.

         Depreciation  and  amortization  increased $2.0 million to $2.4 million
for Fiscal 1995 from $0.4 million for Fiscal 1994 as a result of amortization of
intangible assets related to acquisitions and depreciation of  newly-operational
networks.

         OTHER  EXPENSES.  Other expenses  increased $.2 million to $1.9 million
for Fiscal 1995 from $1.7 million for Fiscal 1994.  Contributing to the increase
was an $.8 million increase in interest expense  resulting from borrowings under
the Tomen Facility and a $.5 million write-off of investments.  Offsetting these
increases  was a $.4  million  decrease  in the  loss on joint  ventures  due to
improved operating results at the Phoenix Fiber network.

Additionally,  in Fiscal 1994 the Company wrote-off $.7 million in pre-operating
costs at GST Telecom. No such losses were realized in Fiscal 1995.

LIQUIDITY AND CAPITAL RESOURCES

         The  Company has  incurred  significant  operating  and net losses as a
result of the  development  and operation of its networks.  The Company  expects
that such  losses  will  continue as the  Company  emphasizes  the  development,
construction  and  expansion of its networks and builds its customer  base,  and
that cash provided by operations will not be sufficient to fund the expansion of
its networks and services.

         Net cash provided by financing  activities  from  borrowings and equity
issuances to fund capital  expenditures,  acquisitions  and operating losses was
$276.9 million,  $192.7 million, $194.3 million, $38.0 million and $10.9 million
for the nine months  ended June 30,  1997,  the nine months ended June 30, 1996,
Fiscal 1996, Fiscal 1995 and Fiscal 1994,  respectively.  The Company's net cash
used in operating and investment  activities was $299.9 million,  $75.2 million,
$139.0  million,  $36.2 million and $11.4 million for the nine months ended June
30,  1997,  the nine months ended June 30,  1996,  Fiscal 1996,  Fiscal 1995 and
Fiscal 1994, respectively.

   
         Capital  expenditures for the nine months ended June 30, 1997, the nine
months ended June 30, 1996, Fiscal 1996, Fiscal 1995 and Fiscal 1994 were $168.4
million,   $44.0  million,  $97.6  million,  $33.9  million  and  $1.4  million,
respectively. The Company anticipates making substantial capital expenditures in
the  future.  The  majority  of these  expenditures  is  expected to be made for
network  construction  and the  purchase of switches  and related  equipment  to
facilitate  the offering of the  Company's  services.  In addition,  the Company
expects to continue to incur operating  losses while it expands its business and
builds its customer base. Actual capital  expenditures and operating losses will
depend on numerous  factors  beyond the Company's  control,  including  economic
conditions,   competition,  regulatory  developments  and  the  availability  of
capital.
    

         In September  1996, the Company entered into the Siemens Loan Agreement
that  provides  for loans by Siemens of up to an  aggregate  of $226  million to
finance the  purchase of Siemens  equipment  and  certain  equipment  from other
suppliers.  $116  million of such loan  proceeds is  presently  available to the
Company.  The Company  may seek to obtain the balance of such  proceeds on an as
needed basis, subject to the negotiation and execution of mutually  satisfactory
documentation.  In  December  1996,  the  Company  entered  into the  NTFC  Loan
Agreement,  which provides for $50 million of equipment financing to finance the
purchase of equipment and products from Nortel. As of June 30, 1997, the Company
has borrowed $4.5 million and $44.6 million from Siemens and NTFC, respectively,
pursuant to these  agreements.  See  "Description  of Certain  Indebtedness  and
Redeemable Preferred Shares -- Equipment Financing."

         In October 1996, the Company  completed the Special  Warrant  Offering,
consisting  of two  million  Common  Shares and  warrants  to  purchase up to an
additional  one million  Common Shares at $13.00 per share for one year from the
date of issuance. The Company received $20.8 million in net proceeds conjunction
with the sale of the two million Common Shares.

         In February 1997, the Company  consummated the Princes Gate Investment,
a  private  placement  of  $50  million  of  Redeemable  Preferred  Shares.  The
Redeemable  Preferred  Shares,  which are convertible at any time after February
28, 2000 at an imputed  price of $11.375 per share,  will not pay  dividends  in
cash,  except  to the  extent  cash  dividends  are paid on  Common  Shares.  In
addition,  the  liquidation  and redemption  prices of the Redeemable  Preferred
Shares will accrete at a semi-annual  rate of 11 7/8%. On February 28, 2004, and
under  certain  circumstances,  the  Redeemable  Preferred  Shares  will also be
subject to mandatory  conversion or redemption,  provided that to the extent the
Company is prohibited from paying the redemption  price in cash,  holders of the
Redeemable  Preferred Shares may elect to convert such shares into Common Shares
and if  such  election  is not  made,  the  Company  may  extend  the  mandatory
redemption date to August 28, 2007. See "Description of Certain Indebtedness and
Redeemable Preferred Shares -- Redeemable Preferred Shares."

         In February  1997,  NACT  completed an initial  public  offering of its
common  stock  pursuant  to which the  Company and NACT sold one million and two
million shares, respectively,  of NACT's common stock, resulting in net proceeds
to the  Company  and NACT of  approximately  $9.1  million  and  $18.2  million,
respectively.

         In May 1997, GST Funding  completed the May Offering of $265 million of
the Old Notes.  Of the $255.8  million of net proceeds  from the issuance of the
Notes,  as of June 30,  1997  approximately  $93.8  million was used to purchase
Pledged  Securities  to fund the first six  interest  payments  on the Notes and
approximately  $54.3  million was used to  purchase  Acquired  Equipment  ($41.5
million of which was used to refinance intercompany indebtedness). The Indenture
and the 1995 Indentures include restrictive  covenants which, among other items,
limit or restrict additional indebtedness incurred by the Company, investment in
certain subsidiaries, the sale of assets and the payment of dividends.

         The Company proposes to incur  significant  additional  indebtedness to
purchase telecommunications equipment such as switches and fiber optic cable and
to  finance  related  design,   development,   construction,   installation  and
integration costs. The Company may make public and private offerings of its debt
and equity securities and may negotiate additional credit facilities.

         The Company's cash debt service  obligations,  including  principal and
interest payments, for the next five fiscal years are as follows:

                1998            $ 53.0 million
                1999            $ 58.8 million
                2000            $ 58.0 million
                2001            $ 93.4 million
                2002            $102.3 million

         At  June  30,  1997,  the  Company  had  cash,  cash  equivalents,  and
investments,  including  restricted  cash and  investments,  of $249.8  million,
compared to $82.5  million at September 30, 1996.  Management  believes that the
cash on hand, borrowings expected to be available under the Tomen Facility,  the
NTFC  agreement  and  the  Siemens  agreement,   and  proceeds  from  securities
offerings,  if any, will provide  sufficient funds for the Company to expand its
business as presently  planned and to fund its operating  expenses  through June
1998.  Thereafter,  the Company expects to require additional financing.  In the
event that the Company's plans or assumptions  change or prove to be inaccurate,
or its cash  resources,  together with  borrowings  under the current  financing
arrangements  prove  to  be  insufficient  to  fund  the  Company's  growth  and
operations,  or if the Company consummates additional acquisitions,  the Company
may be  required to seek  additional  sources of capital  sooner than  currently
anticipated.  There  can be no  assurance  that  the  Tomen  Facility  or  other
financing  will be  available  to the Company or, if  available,  that it can be
concluded on terms acceptable to the Company or within the limitations contained
within the Company's  financing  arrangements.  Failure to obtain such financing
could  result  in the  delay  or  abandonment  of some  or all of the  Company's
development  or expansion  plans and could have material  adverse  effect on the
Company's business.  Such failure could also limit the ability of the Company to
make  principal  and  interest  payments on its  outstanding  indebtedness.  The
Company  has no working  capital or other  credit  facility  under  which it may
borrow for working capital and other general corporate purposes. There can be no
assurance that such a facility will be available to the Company in the future or
that if such a facility were available,  that it would be available on terms and
conditions acceptable to the Company.

         The Company's liquidity  substantially improved as a result of the 1995
Notes  Offering and the May  Offering  because the 1995 Notes do not require the
payment of cash interest  prior to June 2001 and the 1995 Notes and Notes do not
require the payment of principal until maturity in 2005 and 2007,  respectively.
However, a portion of the indebtedness under the Tomen Facility and a portion of
the equipment financing will mature prior to 2005. Accordingly,  the Company may
need to refinance a substantial amount of indebtedness. In addition, the

                                      -49-

<PAGE>

Company anticipates that cash flow from operations will be insufficient to repay
the 1995 Notes and Notes in full at maturity and that such notes will need to be
refinanced.  The  ability of the  Company to effect  such  refinancings  will be
dependent upon the future  performance of the Company,  which will be subject to
prevailing  economic  conditions  and to financial,  business and other factors,
including  factors beyond the control of the Company.  There can be no assurance
that the Company  will be able to improve its earnings  before fixed  charges or
that the Company  will be able to meet its debt service  obligations,  including
its  obligations  under the Tomen  Facility,  the 1995  Notes,  the Notes or its
equipment financing.

NEW ACCOUNTING PRONOUNCEMENTS

         In February 1997,  the Financial  Accounting  Standards  Board ("FASB")
issued Statement of Financial  Accounting Standard No. 128. "Earnings per Share"
("SFAS 128").  This  statement  establishes a different  method of computing net
income per share than is currently  required  under the provisions of Accounting
Principles Board Opinion No. 15. Under SFAS 128. the Company will be required to
present both basic net income per share and diluted net income per share.  Basic
net income per share is expected to be  comparable  or slightly  higher than the
currently presented net income per share as the effect of dilutive stock options
will not be  considered  in  computing  basic net income per share.  Diluted net
income  per share is  expected  to be  comparable  or  slightly  lower  than the
currently presented net income per share since the diluted calculation will also
use the  average  market  price  instead of the higher of the  average or ending
market price for its calculations.  The Company expects to adopt SFAS 128 in the
first quarter of fiscal 1998 and, at that time,  all  historical  net income per
share data presented will be restated to conform to the provisions of SFAS 128.

INCOME TAXES AND ADOPTION OF NEW ACCOUNTING STANDARDS

         At  September  30,  1996,  the Company had a U.S.  net  operating  loss
carryforward  of  approximately  $45.0 million and a Canadian net operating loss
carryforward of approximately  Cdn. $6.8 million.  While such loss carryforwards
are available to offset future taxable  income of the Company,  the Company does
not expect to  generate  sufficient  taxable  income so as to  utilize  all or a
substantial  portion  of such  loss  carryforwards  prior to  their  expiration.
Further,  the  utilization  of net operating loss  carryforwards  against future
taxable income is subject to limitation if the Company experiences an "ownership
change" as defined in Section 382 of the Code and the analogous provision of the
Canada Act.

         In March  1995,  the FASB  issued  Statement  of  Financial  Accounting
Standards  ("SFAS") No. 121 "Accounting for the Impairment of Long-Lived  Assets
and for Long-Lived  Assets Disposed Of." SFAS No. 121 provides specific guidance
regarding  when  impairment  of long-lived  assets such as plant,  equipment and
certain  intangibles  including goodwill should be recognized and how impairment
losses of such assets  should be measured.  SFAS No. 121 is effective for fiscal
years  beginning after December 15, 1995. The Company is preparing to adopt SFAS
No. 121 in Fiscal 1997 and expects the impact on its  statements  of  operations
will not be material.

         In October  1995,  the FASB issued  Statement No. 123  "Accounting  for
Stock-Based Compensation," which must be adopted by the Company. As permitted by
FASB  Statement No. 123, the Company has elected not to implement the fair value
based accounting method for employee stock options and will disclose, commencing
in Fiscal  1997,  the pro forma net  income  and  earnings  per share as if such
method had been used to account for stock-based compensation cost.

                                    BUSINESS

OVERVIEW

         The  Company  provides a broad range of  integrated  telecommunications
products and services, primarily to customers located in the western continental
United States and Hawaii. As a CLEC, the Company operates

                                      -50-

<PAGE>
state-of-the-art,   digital   telecommunications   networks   that   provide  an
alternative  to ILECs.  The  Company  provides,  through its  established  sales
channels,  telecommunications  services that include long distance, Internet and
data transmission services and recently introduced local dial tone services. The
Company also  produces  advanced  telecommunications  switching  platforms  with
integrated applications software and network telemanagement capabilities through
its equipment subsidiary, NACT.

         The  Company's  digital  networks  currently  serve  cities in Arizona,
California,  Hawaii,  New Mexico and  Washington.  In addition,  the Company has
networks under  construction  which, when completed will serve additional cities
and expand its  regional  footprint  to Idaho,  Oregon,  Utah and five  Hawaiian
Islands.

         Management believes that the Company has an opportunity to leverage its
network  infrastructure  and service  capabilities  to provide  customers with a
complete    solution    to   their    telecommunications    requirements.    The
Telecommunications  Act and  state  regulatory  initiatives  have  substantially
changed the telecommunications regulatory environment in the United States. As a
result of these regulatory changes, the Company is permitted, in certain states,
to  provide  local  dial tone in  addition  to its  existing  telecommunications
service offerings.  In order to capitalize on these  opportunities,  the Company
has accelerated  the development of additional  networks within its region while
significantly  expanding  its  product  and service  offerings,  primarily  with
respect to the provision of local services.

         GST Funding is a special  purpose  finance  subsidiary  of the Company,
formed to issue the Old Notes,  to purchase  equipment  with the proceeds of the
May  Offering,  GST Funding acts as a purchasing  agent for GST USA and sells to
GST USA the equipment it purchases.  Ultimately, such equipment is leased to the
operating subsidiaries of the Company by GST USA.

TELECOMMUNICATIONS SERVICES MARKET

         As  reported  by  the  FCC,  ILECs  in  the  United  States   generated
approximately  $96.8  billion  in revenue  in 1995 from the  provision  of local
exchange  services.  Local  exchange  services  consist  of a number of  service
components  and are defined by specific  regulatory  classifications.  For 1995,
total revenue by service was (i)  interstate  dedicated  access  service  (i.e.,
connecting a customer to a long distance carrier's  facilities) revenues of $3.0
billion;  (ii)  interstate  switched  access  service  (i.e.,   originating  and
terminating calls from a long distance carrier) revenues of $12.2 billion; (iii)
end-user  fees (i.e.,  access  charges  paid by the  consumer for the use of the
ILECs' networks) of $7.1 billion; (iv) basic local service (including dial tone,
local area  charges,  dedicated  point-to-point  intraLATA  service and enhanced
calling features) revenues of $46.1 billion; (v) intraLATA toll call revenues of
$10.8 billion;  (vi)  intrastate  switched access (i.e.,  local  origination and
termination  for long  distance  carriers for calls within a state)  revenues of
$7.4 billion;  and (vii)  miscellaneous  (including  provisions of  directories,
billing and  collection  services and  corporate  operations)  revenues of $10.3
billion.  In addition,  the FCC reported that total toll service revenues in the
United States in 1995 were $83.8 billion.

         Until recently,  the competitive access provider  ("CAP")/CLEC industry
has generally been limited to providing special access services and private line
services to  corporations  and  government  agencies  physically  located on the
network of the CAP/CLEC.  The Telecommunications Act opens local service markets
to  competition  by  preempting  state and local  laws,  to the extent that they
prevent   competitive   entry   with   respect   to   the   provision   of   any
telecommunications  service,  and  imposes a variety  of new  duties on ILECs in
order to promote competition in local exchange and access services.

TELECOMMUNICATIONS NETWORKS

         The Company's networks comprise fiber optic cables,  microwave or other
wireless facilities, integrated switching facilities, advanced electronics, data
switching equipment, transmission equipment and associated wiring and equipment.
The  Company  typically  designs  its  networks  with a ring  architecture  with
connectivity to the ILEC's

                                      -51-

<PAGE>

central offices, points-of-presence ("POPs") of long distance carriers and large
concentrations of telecommunication intensive end-users.

         The Company's decision to construct a network in a particular locale is
preceded  by a  review  of the  area's  demographic,  economic  and  competitive
characteristics  and   telecommunications   requirements.   The  characteristics
examined include location and concentration of potential business,  governmental
and academic end-users,  the locale's economic prospects,  information regarding
demand for the various  services offered by the Company and actual and potential
ILEC,  CLEC and other  competitors.  Market  demand is  estimated  using  market
research  conducted  by the  Company  and from  information  such as demand sets
provided by interexchange carriers ("IXCs").

TELECOMMUNICATIONS NETWORK STRATEGY

         The Company's network strategy is to continue to develop and expand its
network  infrastructure to ultimately  assemble,  through a combination of owned
and leased facilities and joint ventures, an integrated regional network for the
on-net  provision of CLEC services,  including  local,  long distance,  Internet
access and data  services.  The  Company  will  continue to focus on the western
United  States  in order to take  advantage  of its  strategically  advantageous
position in California and Hawaii and the substantial telecommunications traffic
that exists among the western United States, Mexico, the Pacific Rim and western
Canada.

TELECOMMUNICATIONS SERVICES STRATEGY

         In conjunction with its network expansion,  the Company has developed a
strategy to leverage its existing  infrastructure,  customer base and experience
by providing a broad range of integrated telecommunications services to meet the
voice and data  needs of its  end-user  customers.  The  Company's  sales  force
primarily  focuses on business,  government  and academic  end-users  within its
region  that have  significant  telecommunications  requirements.  To meet these
customers' needs, the Company offers a number of CLEC services including:

         LOCAL SERVICES

         Local services involve the transmission of voice, video or data to long
distance carrier-specified or end-user-specified termination sites. By contrast,
the special access services historically provided by the Company and other CLECs
involve a fixed  communications  link, usually between a specific end-user and a
specific long  distance  carrier's  POP.  With a switch,  it is possible for the
Company to direct a long distance carrier's traffic to any end-user provided the
end-user is connected to the Company's network directly or indirectly through an
ILEC's network with which the Company has an  interconnection  agreement.  Under
current federal regulations, the Company is permitted to provide a full range of
interstate  switched access and enhanced services.  In addition,  a switch gives
the  Company  the  technological  capability  to provide the full range of local
telephone services, although state authority is necessary for intrastate service
offerings. See "--Regulation."

         The Company  plans to continue to install  switching  equipment  in its
operational  networks,  in  markets  where it is  constructing  networks  and in
certain  other  cities  where  the  Company  will  rely on ILEC  facilities  for
transmission, as demand warrants. Once a switch is operational, where regulatory
conditions and  interconnection  agreements permit, the Company intends to offer
local dial tone, in addition to enhanced services such as ISDN,  Centrex,  voice
mail and other custom calling  features.  See "Risk Factors --  Difficulties  in
Implementing Local and Enhanced Services."

         LONG DISTANCE SERVICES

         The Company offers basic and enhanced long distance  services,  such as
toll free,  calling  card,  prepaid  calling  card and  international  call back
services,  targeting  primarily business  customers  purchasing between $200 and
$15,000  of  service  per month as well as  resellers  and other  carriers.  The
Company  supplies  long distance  services  pursuant to resale  agreements  that
enable it to utilize the network facilities of major long distance carriers

                                      -52-

<PAGE>

such as MCI and AT&T.  The  Company  has  recently  expanded  its long  distance
products  and  services  through  the  acquisition  of Action  Telcom,  GST Call
America,  TotalNet  and the  business of  Texas-Ohio  and intends to continue to
pursue  acquisitions  of long  distance  carriers.  See "Risk  Factors  -- Risks
Relating to Long Distance Business."

         INTERNET SERVICES

         In March 1996, the Company acquired the business of Hawaii On Line, the
largest  Internet  access  provider  in Hawaii.  The  Company is also  presently
providing Internet services to customers in Portland and Vancouver (Washington).
In addition to providing  Internet access, the Company presently offers Web site
development  and  hosting,  provides  EDI  services  and  is in the  process  of
developing  various Internet  software  applications.  Management  believes that
these  services  will become an  important  component of the  Company's  overall
product  offerings  and  will  permit  the  Company  to  leverage  its  existing
infrastructure.  The Company  intends to continue to expand its Internet  access
and service business to other markets.

         DATA SERVICES

         The Company is leveraging its  infrastructure and network experience to
offer data  networking  services  such as high speed LAN  connectivity  service,
video conferencing, multi-media networking, frame relay and high capacity access
to the Internet.

         The Company offers national and  international  frame relay services on
its own frame  relay  network  and  through an  interconnection  agreement  with
Intermedia. Under this agreement, the Company and Intermedia have agreed to link
their  data  networks  and  terminate  one  another's   traffic.   National  and
international   frame   relay   connectivity   is   achieved   with   individual
network-to-network  interface  ("NNI")  agreements  with  Intermedia  and  other
telecommunications  carriers.  In addition to dedicated local loop access to the
Company's frame relay network, the Company has established frame relay NNIs with
Pacific Bell, U S WEST  Communications,  Inc. ("U S WEST"),  SBC  Communications
Corporation ("SBC") and the GTE Companies.

         The Company offers its customers  monthly  network  management  reports
that allow users to track the  performance  of their  virtual  private  network.
Customer network  management support will permit customers to monitor and tailor
their  virtual  private  network as desired with a  communication  link into the
Company's network management systems.

         SHARED TENANT SERVICES

         The  Company   offers  shared  tenant   services  to  large   apartment
communities in  California,  Idaho,  New Mexico,  Oregon,  Utah and  Washington.
Shared tenant services  include local,  long distance,  Internet  access,  cable
television  and home alarm  service.  The  Company  expanded  its shared  tenant
services  business through the acquisition of Tri-Star,  a Seattle-based  shared
tenant services provider in September 1996 for a purchase price of approximately
$2.4 million,  payable in Common  Shares  valued at their then market value,  in
eight quarterly installments commencing in September 1996.

         The  Company  provides  local dial tone  service  to its shared  tenant
customers  through  on-site PBX telephone  systems located within each apartment
complex that are connected to the ILEC.  As the Company  expands its network and
central office switching  facilities,  PBXs will be replaced with central office
access nodes originating from the Company's own dial tone facilities,  which the
Company expects to provide significant cost savings to the Company. In addition,
the Company is in the process of  connecting  apartment  communities  to its own
fiber  network,  thereby  permitting  the  Company  to realize  additional  cost
savings.

MANUFACTURING

         The Company, through its equipment subsidiary,  NACT, produces advanced
telecommunications switching platforms with integrated applications software and
network telemanagement capabilities.  As a single source provider, NACT believes
that  it  is  the  only  company  in  its  market  that  designs,  develops  and
manufactures all hardware and software elements necessary for a fully integrated
turnkey   telecommunications   switching  solution.  Because  NACT  provides  an
integrated  solution,  its  customers do not require the  multiple  suppliers of
hardware and value added resellers of software that would otherwise be necessary
to provide a wide range of end-user services and applications.  NACT's customers
include long distance carriers,  prepaid debit card and prepaid cellular network
operators,  international call back/reorigination  providers and other specialty
service providers.

   
         The  Company  and  NACT  sold  one  million  and  two  million  shares,
respectively,  of NACT's common stock in the NACT  Offering,  resulting in gross
proceeds  to  the  Company  and  NACT  of  $10.0  million  and  $20.0   million,
respectively.  As a result of the NACT Offering,  the Company's interest in NACT
has  been  reduced  to  approximately  63%.  See  "Prospectus  Summary  - Recent
Developments."

SALES AND MARKETING

         Although   the   Company    initially    marketed   its   services   to
telecommunications-intensive  businesses  and  long  distance  carriers,  it has
expanded  its target  market to include  small to  medium-sized  businesses  and
residential  customers.  The Company  primarily  markets its services  through a
direct sales force,  an inside  sales and  telemarketing  group and a network of
independent  agents.  The Company  intends to expand its sales  force  primarily
through the addition of representatives in its existing offices.

         The Company's  direct sales  personnel offer the Company's full line of
products  including  long  distance,   Internet,  local  and  data  transmission
services.  Teams of sales engineers and product experts are available to support
the sales  force in  complex or  technical  applications.  The inside  sales and
telemarketing  group generates leads for the direct sales force and also focuses
on small  customers  that may use the full array of products  but do not require
extensive  technical  or on-site  support.  Local  customer  service  support is
supplemented  by a centralized  group of customer  service  representatives  who
respond to customer inquiries and perform account maintenance.

COMPETITION

         The telecommunications industry is highly competitive. In most markets,
the Company's principal competitor is the RBOC or the GTE Companies.  Additional
competitors  include other CAPs and CLECs,  such as Brooks Fiber Properties Inc.
("Brooks"),  Teleport  Communications  Group, Inc., MFS Communications  Company,
Inc. ("MFS"),  American  Communications  Services Inc. ("ACSI") and ICG, and may
include microwave and satellite carriers, wireless telecommunications  providers
and private  networks built by large  end-users.  Potential  competitors  (using
similar or different technologies) include cable television companies, utilities
and ILECs outside  their  current  local service area. In addition,  the Company
anticipates future competition from large long distance carriers,  such as AT&T,
MCI and Sprint,  which have begun to offer  integrated  local and long  distance
telecommunications    services   as   regulations   allow.    Consolidation   of
telecommunications companies and the formation of strategic alliances within the
telecommunications industry as well as the development of new technologies could
give rise to significant new competitors to the Company.

         As a  recent  entrant  in the  integrated  telecommunications  services
industry,  the  Company  has not  achieved  and does not  expect  to  achieve  a
significant market share for any of its services. In particular,  the RBOCs, the
GTE  Companies  and  other  local   telephone   companies   have   long-standing
relationships  with their  customers,  have  financial,  technical and marketing
resources substantially greater than those of the Company, have the potential to
subsidize  competitive  services with revenues from a variety of businesses  and
currently  benefit from certain  existing  regulations that favor the ILECs over
the  Company  in certain  respects.  While  recent  regulatory  and  legislative
initiatives allow CLECs such as the Company to interconnect with ILEC facilities
and  provide   increased   business   opportunities   for  the   Company,   such
interconnection   opportunities  have  been  accompanied  by  increased  pricing
flexibility  for, and  relaxation  of regulatory  oversight  of, the ILECs.  For
example,  the  FCC  granted  ILECs  additional   flexibility  in  pricing  their
interstate  special and switched  access  services on a central office  specific
basis.  Under this pricing  scheme,  ILECs may establish  pricing zones based on
access traffic density and charge  different  prices for central offices in each
zone. On February 8, 1997, new FCC rules became effective allowing ILECs to file
streamlined tariffs on 15 days' notice for rate increases and 7 days' notice for
rate  decreases.  Unless the FCC acts  during the notice  period,  such  tariffs
become effective at its end.

         The  long   distance   telecommunications   industry   has   relatively
insignificant  barriers  to  entry,  numerous  entities  competing  for the same
customers  and a high average churn rate,  as customers  frequently  change long
distance  providers  in response to the  offering of lower rates or  promotional
incentives by  competitors.  The Company  competes  with major  carriers such as
AT&T,  MCI and Sprint,  as well as other  national  and regional  long  distance
carriers and resellers,  many of whom are able to provide services at costs that
are lower than the Company's current costs.  Local telephone  companies may also
enter the long distance market,  subject to certain  conditions.  As a result of
the  Telecommunications  Act, the Company  believes  that RBOCs also will become
competitors  in the  long  distance  telecommunications  industry.  The  Company
believes that the principal competitive factors affecting its long distance

                                      -56-

<PAGE>

operations  are pricing,  customer  service,  accurate  billing,  clear  pricing
policies  and,  to a lesser  extent,  variety of  services.  The  ability of the
Company  to  compete  effectively  will  depend  upon its  continued  ability to
maintain high quality  market driven  services at prices  generally  equal to or
below those charged by its competitors.  The FCC has, on several occasions since
1984,  approved  or required  price  reductions  by AT&T and,  in 1995,  the FCC
announced  that AT&T will no longer be  regulated  as a dominant  long  distance
carrier.  This decision  increased  AT&T's  flexibility in competing in the long
distance  services  market and eliminated the longer tariff notice  requirements
previously  applicable  only to AT&T.  Most recently,  the FCC has adopted rules
that will  eliminate  the  ability  or need of long  distance  carriers  to file
tariffs with the FCC. On February 13, 1997,  the United  States Court of Appeals
for the District of Columbia Circuit stayed the implementation of such rules. To
maintain its  competitive  posture,  the Company  believes  that it must be in a
position to reduce its prices in order to meet  reductions in rates,  if any, by
others. Any such reductions could adversely affect the Company.

         The  Internet  services  market  is  highly  competitive.  There are no
substantial  barriers to entry,  and the Company expects that  competition  will
continue to intensify. The Company's competitors in this market include Internet
access providers, other telecommunications  companies, online services providers
and Internet software providers.

         The market for  telecommunications  equipment is highly competitive and
subject to rapid  technological  change. NACT expects competition to increase in
the future from existing competitors in the distributed switching systems market
and from other  companies  that may enter  NACT's  existing  or future  markets,
including major central office switch vendors. In its manufacturing  operations,
the  Company,  through  its  subsidiary  NACT,  competes  with a number of lower
capacity  switch  manufacturers  such as CPDI,  ITP and PCS  Telecom.  NACT also
competes with providers of open architecture  (programmable)  hardware switching
platforms that are enhanced by applications providers and value added resellers.
Such competitors include Excel, which has agreements with software  applications
providers.  As NACT's business develops and it seeks to market its switches to a
broader  customer  base,  NACT's  competitors  may  include  larger  switch  and
telecommunications  equipment  manufacturers  such as Lucent  Technologies Inc.,
Harris   Corporation,   Siemens  AG,   Alcatel   Alsthom   Compagnie,   Generale
D'Electricite, Telefonaktiebolaget, L.M. Ericcson and Northern Telecom, Ltd.

         Most of the  Company's  actual and potential  competitors  in its local
services, long distance, Internet and data services and manufacturing businesses
have substantially greater financial, technical and marketing resources than the
Company.  While the  Company  believes  that it is well  positioned  to  compete
effectively, there can be no assurance that it will be able to do so.

         The recent WTO  agreement on basic  telecommunications  services  could
increase the Company's competition.  Under this agreement, the United States and
other   members   of   the   WTO   committed   themselves   to   opening   their
telecommunications  markets to competition and foreign ownership and to adopting
regulatory measures to protect competitors against  anticompetitive  behavior by
dominant telephone companies, effective as early as January 1, 1998.

REGULATION

         The  Company's  telecommunications  services  business  is  subject  to
varying degrees of federal, state and local regulation.

         FEDERAL REGULATION

         The  FCC  regulates  interstate  and  international   telecommunication
services.  The allocation of jurisdiction  between federal and state  regulators
over  dedicated  circuits  that carry both  interstate  and  intrastate  traffic
(including   private  line  and  special  access  services)   creates  difficult
definitional issues. The FCC, however, has noted that private line, non-switched
telecommunications  services can be classified,  at least for rate purposes,  as
jurisdictionally interstate (subject to FCC jurisdiction) if at least 10% of the
traffic carried over a particular dedicated line is

                                      -57-

<PAGE>

interstate  in  nature.   The  FCC  has  not  ruled   specifically   as  to  the
jurisdictional nature of the traffic carried over the Company's networks.

         The Company  provides service either on a private carrier basis or on a
common  carrier  basis.  In the interstate  market,  the primary  distinguishing
factor between  private  carriers and common carriers is that the former provide
customized  services to select  customers  pursuant to  individually  negotiated
contracts.  Common carriers, on the other hand, hold themselves out to serve the
public generally. The FCC imposes certain regulations on common carriers such as
the RBOCs that have some degree of market power. The FCC imposes less regulation
on common carriers without market power including, to date, CAPs/CLECs.  The FCC
requires  common carriers to receive an  authorization  to construct and operate
telecommunication facilities between the United States and international points.

         In August  1996,  the FCC released its  Interconnection  Decision.  The
Interconnection  Decision establishes rules implementing the  Telecommunications
Act requirements  that ILECs negotiate  interconnection  agreements and provides
guidelines for review of such agreements by state public utilities  commissions.
On  July  18,  1997,  the  Eighth  Circuit  vacated  certain   portions  of  the
Interconnection   Decision,   including   provisions   establishing   a  pricing
methodology  and a procedure  permitting new entrants to "pick and choose" among
various  provisions  of existing  interconnection  agreements  between ILECs and
their  competitors.  The  Company  had  negotiated  a number of  interconnection
agreements with ILECs prior to this Eighth Circuit decision.  The Eighth Circuit
decision  creates  uncertainty  about the  rules  governing  pricing,  terms and
conditions  of  interconnection   decisions,  and  could  make  negotiating  and
enforcing  such  agreements  more  difficult  and  protracted  and  may  require
renegotiation of existing agreements. There can be no assurance that the Company
will be able to obtain or enforce interconnection agreements on terms acceptable
to the Company.  The FCC has  announced  that it will seek a writ of  certiorari
from the Supreme Court.

         In October 1996,  the FCC adopted an Order in which it  eliminated  the
requirement that non-dominant  interstate  carriers such as the Company maintain
tariffs  on file  with the FCC for  domestic  interstate  services.  This  Order
applies to all non-dominant interstate carriers,  including AT&T. The Order does
not apply to the RBOCs or other local  exchange  providers.  The FCC's Order was
issued pursuant to authority granted to the FCC in the Telecommunications Act to
"forbear" from regulating any  telecommunications  services  provider if the FCC
determines  that  the  public  interest  will  be  served.  After  a  nine-month
transition period, relationships between interstate carriers and their customers
will be set by contract.  At that point long  distance  companies  may no longer
file with the FCC  tariffs for  interstate,  domestic,  interexchange  services.
Carriers have the option to immediately  cease filing  tariffs.  Several parties
have  filed  notices  for  reconsideration  of the FCC order  and other  parties
appealed the decision.  On February 13, 1997, the United States Court of Appeals
for the District of Columbia Circuit stayed the implementation of the FCC Order.

         If  the  stay  is  lifted   and  the  FCC  Order   becomes   effective,
telecommunications  carriers such as the Company, will no longer be able to rely
on the  filing  of  tariffs  with  the FCC as a means  of  providing  notice  to
customers of prices,  terms and conditions on which they offer their  interstate
services.  The  obligation to provide  non-discriminatory,  just and  reasonable
prices remains unchanged under the  Communications  Act of 1934, as amended (the
"Communications  Act").  While tariffs  provided a means of providing  notice of
prices,  terms and  conditions,  the Company has always relied  primarily on its
sales force and direct  marketing to provide such  information  to its customers
and expects to continue to do so in the future.

         The  Telecommunications  Act is intended to increase  competition.  The
Telecommunications  Act opens the local  services  market by requiring  ILECs to
permit  interconnection to their networks and establishing ILEC obligations with
respect to:

         RECIPROCAL  COMPENSATION.  Requires  all ILECs  and  CLECs to  complete
Telecommunications  calls  originated  by competing  carriers  under  reciprocal
arrangements at prices based on a reasonable  approximation  of incremental cost
or through mutual exchange of traffic without explicit payment.

                                      -58-

<PAGE>

         RESALE.  Requires  all  ILECs  and  CLECs  to  permit  resale  of their
telecommunications  services without unreasonable restrictions or conditions. In
addition,  ILECs are required to offer wholesale versions of all retail services
to other  telecommunications  carriers for resale at discounted rates,  based on
the costs avoided by the ILEC in the wholesale offering.

         INTERCONNECTION.   Requires   all  ILECs  and  CLECs  to  permit  their
competitors to interconnect with their facilities.  Requires all ILECs to permit
interconnection  at any  technically  feasible point within their  networks,  on
nondiscriminatory terms, at prices based on cost (which may include a reasonable
profit).  At the option of the carrier seeking  interconnection,  collocation of
the  requesting  carrier's  equipment  in the ILECs'  premises  must be offered,
except  where the ILEC can  demonstrate  space  limitations  or other  technical
impediments to collocation.

         UNBUNDLED  ACCESS.  Requires  all  ILECs to  provide  nondiscriminatory
access to unbundled network elements (including, network facilities,  equipment,
features,  functions, and capabilities) at any technically feasible point within
their networks,  on nondiscriminatory  terms, at prices based on cost (which may
include a reasonable profit).

         NUMBER  PORTABILITY.  Requires  all ILECs and CLECs to permit  users of
telecommunications   services  to  retain  existing  telephone  numbers  without
impairment  of quality,  reliability  or  convenience  when  switching  from one
telecommunications carrier to another.

         DIALING  PARITY.  Requires  all ILECs and CLECs to  provide  "1+" equal
access to competing  providers of telephone  exchange  service and toll service,
and to provide nondiscriminatory access to telephone numbers, operator services,
directory  assistance,  and  directory  listing,  with no  unreasonable  dialing
delays.

         ACCESS  TO  RIGHTS-OF-WAY.  Requires  all  ILECs  and  CLECs to  permit
competing  carriers  access to  poles,  ducts,  conduits  and  rights-of-way  at
regulated prices.

         ILECs are required to negotiate in good faith with carriers  requesting
any or all of the above arrangements.  If the negotiating  carriers cannot reach
agreement  within  a  prescribed  time,   either  carrier  may  request  binding
arbitration of the disputed issues by the state regulatory commission.  Where an
agreement  has  not  been  reached,  ILECs  remain  subject  to  interconnection
obligations  established  by the  FCC  and  state  telecommunication  regulatory
commissions.

         The  Telecommunications  Act also  codifies the ILECs' equal access and
nondiscrimination  obligations and preempts  inconsistent state regulation.  The
Telecommunications  Act also contains special provisions that eliminate the AT&T
Antitrust  Consent  Decree  (and  similar  antitrust  restrictions  on  the  GTE
Companies)  restricting  the RBOCs from  providing  long  distance  services and
engaging in telecommunications equipment manufacturing.  These provisions permit
a RBOC to enter the long distance market in its  traditional  service area if it
satisfies several procedural and substantive  requirements,  including obtaining
FCC approval upon a showing that facilities-based  competition is present in its
market,  that the RBOC has  entered  into  interconnection  agreements  in those
states in which it seeks long distance relief,  the  interconnection  agreements
satisfy a  14-point  "checklist"  of  competitive  requirements,  and the FCC is
satisfied  that the  RBOC's  entry into long  distance  markets is in the public
interest.  SBC,  the RBOC  serving  some of the  states  served by the  Company,
applied to the FCC for such authority.  The FCC denied the SBC request.  SBC has
filed suit  challenging the  constitutionality  of the checklist  provisions and
separately  appealed the FCC denial of its application.  The  Telecommunications
Act  permits  the  RBOCs  to  enter  the  out-of-region   long  distance  market
immediately upon its enactment.

         Under  the   Telecommunications   Act,  any  entity,   including  cable
television   companies   and   electric  and  gas   utilities,   may  enter  any
telecommunications  market,  subject to reasonable  state  regulation of safety,
quality   and   consumer    protection.    Because    implementation    of   the
Telecommunications   Act  is  subject  to  numerous  federal  and  state  policy
rulemaking proceedings and judicial review there is still uncertainty as to what
impact such legislation will have on the Company.

                                      -59-

         GST Pacwest  Telecom Hawaii  Incorporated  ("GPTHI")  holds a submarine
cable landing  license from the FCC, which  authorizes the Company to construct,
operate and land an undersea cable between and among the Hawaiian  Islands.  GST
Telecom  also holds a submarine  cable  landing  license  for an undersea  cable
between Guam and the Commonwealth of the Northern Mariana Islands.
    

         Pursuant  to  authority  granted by the FCC,  the  Company  resells the
international  telecommunications  services of other common carriers between the
United  States and  international  points.  In connection  with such  authority,
certain of the  Company's  subsidiaries  have filed  tariffs  stating the rates,
terms and conditions for their  international  services.  The FCC has determined
that call  reorigination  service  using  uncompleted  call  signaling  does not
violate  United  States or  international  law, but has held that United  States
companies  providing such services must comply with the laws of the countries in
which they operate as a condition of such companies' Section 214 authorizations.

         With respect to its domestic service offerings, various subsidiaries of
the  Company  have filed  tariffs  with the FCC  stating  the  rates,  terms and
conditions for their interstate  services.  To the extent that such subsidiaries
provide intrastate services, they may be required to obtain authority from state
regulatory authorities prior to providing such services.  Such subsidiaries have
been granted  authority in  approximately  40 states and the Company is applying
for such  authority in the remaining 10 states.  There can be no assurance  that
such state authorizations will be granted.

         NACT   is   authorized   by   the   FCC   to   provide    international
telecommunications services. Any intrastate telecommunications services provided
by NACT may require  authority from state  regulatory  agencies and tarrifing of
the services  and any  interstate  services  require NACT to file an FCC tariff.
There can be no assurance that such authorizations will be granted.

         Except in certain  designated  geographically  competitive  zones,  the
current policy of the FCC for most special access  services  dictates that ILECs
charge  all  customers  the same  price for the same  service.  Thus,  the ILECs
generally  cannot lower prices to those  customers  likely to contract for their
services  without also lowering charges for the same service to all customers in
the same geographic area, including those whose telecommunications  requirements
would not justify the use of such lower prices. The FCC may, however,  alleviate
this  constraint  on the ILECs and permit them to offer special rate packages to
very large customers, as it has done in few cases, or permit other forms of rate
flexibility.  The  FCC has  adopted  proposals  that  significantly  lessen  the
regulation of ILECs that are subject to  competition  in their service areas and
provide  such ILECs with  additional  flexibility  in pricing  their  interstate
switched and special access on a central office  specific basis. On May 7, 1997,
the FCC adopted  rules which will require  ILECs to  substantially  decrease the
prices they charge for switched and special  access.  At the same time,  the FCC
adopted rules that will change how access charges are calculated.  These changes
will reduce access  charges and will shift certain  charges  currently  based on
minutes to  flat-rate,  monthly  per-line  charges.  The FCC has also  requested
comments on whether it should impose usage sensitive charges on Internet service
providers which are presently exempt from access charges.

   
         Under the  Communications  Act and other federal  regulations,  foreign
nationals may not own more than 20% of a company, or have more than a 20% voting
interest in a company,  that directly holds a common carrier radio license.  The
Communications Act also prohibits foreign nationals from owning 25% or more of a
company which, in turn,  controls a company holding a radio license,  if the FCC
finds that such alien participation  would not serve the public interest.  Under
the WTO agreement, the United States agreed to increase the foreign ownership up
to 100%,  however while the FCC has proposed rules implementing the WTO policies
there  can be no  assurance  as to when  the FCC will  change  its  policy.  The
operations of GST Hawaii use among other facilities,  microwave radio facilities
operating  pursuant to FCC licenses granted to PNI, an entity controlled by John
Warta, the Chairman of the Board and Chief Executive Officer of the Company.  In
addition,  under the FCC's foreign  ownership rules, the Company cannot hold PCS
licenses. The FCC also has the authority,  which it is not presently exercising,
to impose restrictions on foreign ownership of communications  service providers
not  utilizing  radio  frequencies,  which if  exercised  could  have a material
adverse effect on the Company's business. In addition, the networks may
    

                                      -60-

<PAGE>

subsequently need to obtain radio licenses to "fill in" certain customers in the
networks that are not practical to reach by wire.  Should the Company  require a
common carrier radio license in the future,  it may be prohibited from obtaining
such license because of the foreign ownership restrictions of the Communications
Act.

         STATE REGULATION

         The  Telecommunications  Act is intended to increase competition in the
telecommunications  industry,  especially  in the local  exchange  market.  With
respect to local services,  ILECs are required to allow interconnection to their
networks and to provide  unbundled  access to network  facilities,  as well as a
number of other  procompetitive  measures.  Because  the  implementation  of the
Telecommunications  Act is subject to numerous state  rulemaking  proceedings on
these issues. The Eighth Circuit's decision and the FCC Interconnection Decision
increases  the role of the state  commissions.  It is  difficult  to predict how
quickly full competition for local services,  including local dial tone, will be
introduced.

         State  regulatory  agencies have regulatory  jurisdiction  when Company
facilities and services are used to provide  intrastate  services.  A portion of
the Company's  current  traffic may be  classified  as intrastate  and therefore
subject  to state  regulation.  The  Company  expects  that it will  offer  more
intrastate services (including intrastate switched services) as its business and
product lines expand and state regulations are modified to allow increased local
services competition. To provide intrastate services, the Company generally must
obtain  a  CPCN  from  the  state  regulatory   agency  and  comply  with  state
requirements for telecommunications utilities.

         LOCAL REGULATION

         The networks are subject to numerous local regulations such as building
codes  and  licensing.  Such  regulations  vary on a city by city and  county by
county  basis.  The  Company  needs to obtain  rights-of-way  over  private  and
publicly   owned  land  to  permit   the   installation   of  the  fiber   optic
telecommunication equipment.

GST GLOBAL TELECOMMUNICATIONS INC.

         As of June 30,  1997,  the  Company  has  invested  approximately  $3.7
million in Global and holds  approximately 3.6 million shares. In addition,  the
Company has warrants to purchase 750,000  additional  shares.  On June 30, 1997,
Global had approximately 12.6 million shares  outstanding.  Global will issue to
the  Company  additional  common  shares,  subject to  approval  of the VSE,  in
consideration  for the transfer by the Company to Global of its rights in and to
the Bestel Project.  In addition,  certain executive officers and directors hold
in the aggregate  434,896  shares of Global and options and warrants to purchase
an additional  715,500  Global  common  shares.  The Company  intends to conduct
certain of its international  activities through Global.  Global will employ its
own operating management and raise capital required for its proposed activities.
As of June 30, 1997,  Global had raised  approximately  Cdn. $28 million through
private placements of its common shares.

         Global has acquired, through a subsidiary, GST Mextel, Inc., a Delaware
corporation,  49% of the outstanding shares of Bestel, S.A. de C.V.  ("Bestel").
The total  consideration is approximately  $13.7 million, of which approximately
$8.9  million  has  been  paid.   The   remaining  51%  is  held  by  Occidental
Telecommunicacion,  S.A. de C.V. ("Occidental").  In addition, Global has agreed
to loan an aggregate of up to $36.0  million to Bestel,  of which $20.0  million
has been  advanced  to date.  Bestel  plans to  construct  and  operate  a 2,350
kilometer  fiber  optic  telecommunications   network  in  Mexico  to  become  a
facilities-based  long distance carrier,  of which  approximately 700 kilometers
has been constructed to date.

         Global has also  acquired  from Cable and  Wireless an 80%  interest in
Vitacom,  for a purchase  price of $1.5  million.  The  remaining 20% is held by
Cable and Wireless,  which can require Global to purchase such interest in 1999.
Vitacom is engaged in the provision of voice,  high speed data  information  and
other  services  and the  manufacture  and  sale of VSAT  (very  small  aperture
satellite terminal) and other equipment used to access the Internet.

$127,000.

   
         The Company  also leases  offices  elsewhere in the United  States,  in
Vancouver,  British  Columbia  and in Japan,  pursuant to leases which expire on
various dates through December 31, 2007. The Company's  current aggregate annual
rental expense is approximately $4.5 million.
    

LEGAL PROCEEDINGS

   
         On  August  24,  1995,   Aerotel,   Ltd.  and  Aerotel   U.S.A.,   Inc.
(collectively,  "Aerotel")  commenced  an action  against NACT and a customer of
NACT in the  United  States  District  Court,  Southern  District  of New  York,
alleging that  telephone  systems  manufactured  and sold by NACT  incorporating
prepaid debit card features  infringe upon Aerotel's  patent which was issued in
November 1987 (the "Aerotel  Patent").  The initial  complaint  further  alleged
defamation and unfair  competition as a result of a Special Report  disseminated
by NACT to its customers and tortious  interference  with  prospective  business
relations,  alleging  that NACT  induced  third  parties  to  abandon  licensing
negotiations  with Aerotel.  Aerotel  sought  injunctive  relief,  damages in an
unspecified  amount,  damages of up to three times the damages found for willful
infringement  of the  Aerotel  Patent and an order  requiring  NACT to publish a
written  apology to Aerotel.  NACT filed an answer and  Counterclaim in which it
denied  infringement  of the Aerotel Patent and sought judgment that the Aerotel
Patent is invalid and  unenforceable  and that Aerotel has misused its patent in
violation of antitrust laws. NACT also denied that it has committed  defamation,
unfair   competition  and  tortious   interference  with  prospective   business
relations.  On May 3, 1996, NACT served its motion for summary  judgment,  which
the Court has not yet ruled upon. On January 24, 1997, Aerotel served its motion
to amend its complaint to include as defendants  GST and GST USA as well as Kyle
Love, the former  President of NACT and Dr. Thomas E. Sawyer,  a director of GST
and the former Chairman and Chief  Executive  Officer of NACT. The Court granted
this motion in August 1997 and the amended pleading was thereafter  served.  The
amended pleading asserts  substantially the same claims and seeks  substantially
the same relief against NACT as did the earlier complaint and NACT has served an
Amended Answer and  Counterclaims  that is substantially the same as its earlier
pleading.  The amended  pleadings allege that GST and GST USA have infringed the
Aerotel patent,  aided and abetted  infringement by others,  including NACT, and
participated in, and aided and abetted alleged tortious conduct by NACT. GST and
GST USA have served  answers  denying  all  material  allegations  and intend to
defend  vigorously.  Pretrial  discovery  has  commenced  and is scheduled to be
completed  in 1998.  The case is not expected to be tried until late 1998 at the
earliest.  NACT's patent  counsel  believes that NACT has valid  defenses to the
Aerotel  claims.  If  upheld,  these  defenses  would  also  be  valid  for  all
defendants. An unfavorable decision in this action could have a material adverse
effect on the Company.
    

         On July 5, 1994,  the Tucson City Council (the  "Council")  awarded GST
Tucson a  non-exclusive  fiber  optic  communication  license  that  permits GST
Tucson, for a period of 25 years, to conduct, maintain and operate in and across
designated portions of city-owned  rights-of-way.  On June 12, 1995, the Council
approved  the City of Tucson  Competitive  Telecommunications  Code (the "Tucson
Code"),  which was  subsequently  amended on July 10, 1995.  The Tucson Code now
provides,  among other things,  (i) that the City of Tucson grant licenses for a
period of 15

                                      -62-

<PAGE>
   
years,  (ii) for an increase  from 2% to 5 1/2% of gross  revenues to be paid by
licensees and (iii) for cancellation of a license in certain events. The Council
subsequently  refused to permit GST Tucson to modify the route plans  previously
approved  in  order to  construct  connections  between  its  customers  and the
network,  asserting  that GST  Tucson's  existing  license  does not permit such
action and requiring  GST Tucson to receive an amended  license under the Tucson
Code to modify its route plans.  After trying to negotiate a settlement with the
City of Tucson with  respect to its license,  GST Tucson  commenced an action in
the Superior Court of Arizona,  County of Pima,  against the City of Tucson. The
Court  ruled  in favor of the  City  that  the City  Engineer  does not have the
authority  to  grant   modifications   from  the  route  map,  that  such  route
modifications  must be approved by the Council and that the City could condition
GST  Tucson's   application  for  a  franchise  for  intrastate   service  on  a
relinquishment  of GST  Tucson's  existing  license.  GST  Tucson  appealed  the
Superior  Court's  rulings and  subsequently  filed a petition for review in the
Arizona Supreme Court.  On May 13, 1996, GST Tucson  instituted an action in the
United  States  District  Court for the District of Arizona  against the City of
Tucson seeking a declaratory  judgment and injunctive  relief arising out of the
City of Tucson's  failure to manage its public  rights-of-way in a competitively
neutral and nondiscriminatory manner in violation of the Telecommunications Act.
The Court dismissed GST Tucson's action.  GST Tucson filed a Notice of Appeal to
the United States Court of Appeals for the Ninth Circuit on January 16, 1997. On
August 5, 1997,  the Tucson City Council  approved a settlement  agreement  that
resolves the Tucson litigation. Under the terms of the settlement agreement, GST
Tucson  has  agreed to pay the City the  annual  license  fee  called for by the
Tucson Code that amounts to 5 1/2% of gross revenues, and the City has permitted
GST Tucson to modify its current route map and to serve customers throughout the
City limits. While dismissing the pending state court appeal, the parties agreed
to allow the United  States Court of Appeals for the Ninth Circuit to decide the
pending  legal  issue  relating  to whether  companies  like GST Tucson  enjoy a
private right of action to assert  right-of-way  claims under Section  253(c) of
the Telecommunications Act in the United States District Courts.
    

         On or about  February 25, 1997, U S WEST filed a  declaratory  judgment
action against members of the Arizona  Corporation  Commission (the "ACC"),  the
ACC,  ACSI,  Brooks  and the  Company  in the United  States  District  Court in
Arizona. The Company understands that one or more substantially similar lawsuits
have been filed against other CLEC's,  including  MFS. U S WEST alleges that the
ACC has entered into an interconnection  order that unlawfully requires U S WEST
to resell services below cost,  imposes resale  restrictions and denies U S WEST
recovery for construction and implementation  costs,  unlawfully treats the cost
recovery of access revenues for interim number portability, requires U S WEST to
obtain additional rights of way or build additional facilities solely to provide
access to the Company,  and amounts to a taking of U S WEST's  property  without
just  compensation.  U S WEST seeks a declaratory  judgment stating that the ACC
has  violated the  Telecommunications  Act and that the ACC has taken U S WEST's
property without providing just compensation.  U S WEST also seeks an injunction
prohibiting  all  defendants,  including the Company,  from taking any action to
enforce any of the order's allegedly unlawful provisions.  The Company's time to
answer or move against the complaint has been extended indefinitely by U S WEST,
pending a decision with respect to a motion to dismiss the complaint against MFS
in the action filed by U S WEST against it. Should U S WEST prevail in its suit,
it would have an adverse impact on the Company's operations in Arizona; however,
the magnitude thereof is uncertain at this time.

         On or about  April 8,  1997,  U S WEST filed a state  court  proceeding
against the ACC, individual members of the ACC, and GST Net (AZ), Inc. ("GST Net
(AZ)"),  which holds a certificate of convenience and necessity (CCN) to provide
local exchange service in Arizona. In its complaint appealing the ACC's February
6, 1997 decision and order  granting GST Net (AZ) its CCN, U S WEST alleges that
the ACC's  action  violates  certain  requirements  of the Arizona  Constitution
relating to rate of return regulation,  carrier of last resort obligations,  and
equal  protection.  The  appeal  seeks to  subject  GST Net (AZ) and U S WEST to
identical  forms of  regulation,  treating both  carriers as either  traditional
monopoly carriers or as co-equal competitive companies.  GST Net (AZ) answered U
S WEST's  complaint on August 6, 1997,  alleging,  among other things,  that U S
WEST's  complaint is preempted by the  Telecommunications  Act.  Should U S WEST
prevail  in its  appeal,  it  could  have an  adverse  impact  on the  Company's
operations in Arizona; however, the magnitude thereof is uncertain at this time.

         The  Company is not a party to any other  material  legal  proceedings,
nor,  to the  knowledge  of the  Company,  are any  material  legal  proceedings
threatened against the Company. The Company is a party to various

                                      -63-

<PAGE>

proceedings  before the public  utilities  commissions of the states in which it
provides or proposes to provide  telecommunications  services. These proceedings
typically  relate to licensure of the Company or others and to the regulation of
the provision of telecommunications service.

                              CERTAIN TRANSACTIONS

         On June 23, 1994, the Company entered into agreements (the "GST Telecom
Agreements") with Pacwest Network,  L.L.C.  ("Pacwest") (an entity controlled by
John  Warta,  now the  Company's  Chairman  of the  Board  and  Chief  Executive
Officer),  pursuant to which the Company and Pacwest  formed a new  corporation,
GST Telecom, for the purpose of developing  telecommunications  networks.  Under
the  terms of the  agreements,  Pacwest  contributed  the  stock of GST  Pacific
Lightwave,  Inc.,  GST Tucson and GPTHI and the  Company  made  certain  funding
commitments (all of which were  subsequently  satisfied) and contributed its 60%
interest in GST Tucson,  for which the Company received 60% and Pacwest received
40% of the capital  stock of GST Telecom.  Effective  June 1, 1995,  the Company
acquired an  additional  20%  ownership  interest in GST Telecom from Pacwest in
exchange for 1,000,000  Common Shares.  Effective  October 20, 1995, the Company
acquired  Pacwest's  remaining 20% interest in GST Telecom for which Pacwest was
eligible to receive up to a maximum of 1,000,000 Common Shares (valued at $10.00
per Common  Share)  based upon the fair  market  value of a 20%  interest in GST
Telecom,  as  determined  by  independent  appraisal.  The  Company  engaged  an
investment  banking firm to provide such appraisal,  which appraisal valued such
20% interest at not less than $10 million.  In November 1996,  1,000,000  Common
Shares,  which had been held in escrow since October 20, 1995, were  distributed
to the designees of Pacwest, principally Messrs. Warta and Sander.

         Prior to his  employment  with  the  Company,  Mr.  Warta  served,  and
continues  to  serve,  as a  consultant  to  Tomen  for  which he is paid a fee.
Simultaneously  with  the  execution  of the  GST  Telecom  Agreements,  Pacwest
contracted  with the Company to receive a fee equal to 1% of the aggregate  debt
and equity financing provided by Tomen to the Company.  Mr. Sander,  Senior Vice
President and Treasurer of the Company,  is a member of Pacwest and participates
in such  fees.  Since  the  beginning  of  Fiscal  1996,  the  Company  has paid
approximately $645,000 of such fees to Pacwest.

         Under the  Tomen  Facility,  Tomen has the right to act as  procurement
agent for each network project it finances.  The Company has purchased equipment
through Tomen at competitive prices.

         The  operations of the Company's  Hawaiian  microwave  network  require
radio  licenses  from the FCC.  PNI,  an entity  controlled  by Mr.  Warta,  the
Company's  Chairman of the Board and Chief Executive  Officer,  holds the Hawaii
microwave  licenses.  Under agreements  between the Company and PNI, the Company
pays a monthly  fee of $3,000 to PNI and PNI pays an  offsetting  monthly fee to
the Company, in connection with the license and operation of the network.

         Magnacom,  a company controlled by Mr. Warta, the Company's Chairman of
the Board and Chief Executive Officer, won various PCS licenses. Magnacom has 30
MHz (C Block) PCS licenses  for five markets in Arizona,  New Mexico and Oregon;
and  acquired  10 MHz  licenses  in the FCC's F Block in 13  markets  in Hawaii,
Idaho,  Oregon and Washington.  Magnacom has an application pending with the FCC
for the assignment of 6 (C Block) PCS licenses from an unaffiliated entity.

         Magnacom  and the  Company  have  entered  into the  Magnacom  Reseller
Agreement, pursuant to which (i) the Company has been designated a non-exclusive
reseller of PCS telephone services in the markets in which Magnacom has obtained
licenses,  and (ii) Magnacom has agreed to use the Company on an exclusive basis
to  provide  switched  local and long  distance  services,  and  other  enhanced
telecommunications services, to all of Magnacom's resellers in markets where the
Company has  operational  networks.  Magnacom  agreed to sell PCS minutes to the
Company at five cents per minute,  subject to downward  adjustment  to equal the
most favorable rates offered to Magnacom's other resellers (but in no event less
than Magnacom's cost). In connection with the Magnacom Reseller  Agreement,  the
Company has paid to date approximately  $14.0 million as pre-payments for future
PCS services.

         In  addition,  the Company  has been  granted a  conditional  option to
acquire up to a 99%  interest in  Magnacom,  conditioned  upon  Magnacom and the
Company  entering into an agreement  for the  construction  and/or  operation of
Magnacom's  facilities.  The condition precedent to such option has not yet been
met. Such option,  if and when the condition  precedent is met, shall be subject
to compliance with all applicable FCC regulations  relating to prior approval of
any transfer of control of PCS  licenses,  including  those  relating to foreign
ownership  or control.  Accordingly,  until such time as may be permitted by FCC
regulations or administrative  action, the option will be initially limited to a
24% interest in Magnacom.

         In February  1997,  an affiliate of Magnacom,  Guam Net,  acquired from
Poka Lambro Telephone Cooperative,  Inc. a 30 MHz (A Block) PCS license from the
FCC in  the  market  consisting  of  Guam  and  the  Northern  Mariana  Islands.
Concurrently,   the  Company   entered  into  a  reseller   agreement  on  terms
substantially  similar to the Magnacom Reseller  Agreement and paid Guam Net $.4
million as a pre-payment for future PCS services.

         The  provision of wireless  telecommunications  service by Magnacom and
Guam Net will be dependent upon their ability to obtain the financing  necessary
to make payments to the FCC under the terms of their licenses, to obtain working
capital,  and to build  the  required  facilities,  including  the  purchase  of
telecommunications  equipment.  There can be no  assurance  Magnacom or Guam Net
will obtain such financing or be able to provide PCS

                                      -66-

<PAGE>

services.  In such  event,  the  Company  would  likely be unable to recover its
payments to Magnacom and Guam Net.

         In November 1996, 1,500,000 of the common shares of Global owned by the
Company  were  purchased  at cost from W.  Gordon  Blankstein,  presently a Vice
Chairman of the Company and at that time, Chairman of the Company.

         Stephen  Irwin,  a Vice  Chairman and  Secretary of the Company,  is of
counsel to the law firm of Olshan  Grundman Frome & Rosenzweig  LLP,  counsel to
the Company.  In  connection  with such  services,  such firm  received  fees of
approximately  $1.8  million  for each of Fiscal  1996 and Fiscal  1997 and will
receive fees for Fiscal 1998.

         Peter E.  Legault,  a director of the  Company,  is a director and Vice
President  of Thomson  Kernaghan  & Co.  Ltd.,  which was engaged by the Company
during  Fiscal  1996 and Fiscal  1997 to solicit  sources of  financing  for the
Company,  and was one of the placement agents for the Special Warrant  Offering.
In connection with such services,  such firm has received fees of  approximately
$500,000 during Fiscal 1997.

                          DESCRIPTION OF THE NEW NOTES

         The Old Notes were issued under the  Indenture  among GST  Funding,  as
issuer, GST USA, GST and United States Trust Company of New York, as Trustee (in
such capacity, the "Trustee"). The New Notes will be issued under the Indenture,
which will be qualified  under the Trust  Indenture Act of 1939, as amended (the
"Trust Indenture Act"), upon the effectiveness of the Registration  Statement of
which  this  Prospectus  is a part.  The form and terms of the New Notes are the
same in all  material  respects  as the form and terms of the Old Notes,  except
that the  offer and sale of the New Notes  will have been  registered  under the
Securities Act and,  therefore,  the New Notes will not bear legends restricting
transfer thereof.  Upon the consummation of the Exchange Offer, Holders of Notes
will not be entitled to registration rights under, or the contingent increase in
interest rate provided pursuant to, the Registration  Rights Agreement.  The New
Notes  will  evidence  the same debt as the Old Notes and will be  treated  as a
single class under the Indenture with any Old Notes that remain outstanding.

         The terms of the Notes  include those stated in the Indenture and those
made part of the Indenture by reference to the Trust  Indenture Act as in effect
on the date of the  Indenture.  The  Notes  are  subject  to all such  terms and
reference is made to the Indenture  and the Trust  Indenture Act for a statement
thereof.  A copy of the  Indenture  has been  filed  with the  Commission  as an
exhibit to the Registration Statement of which this Prospectus forms a part. The
following  summary  describes  the material  provisions of the Indenture and the
Notes.  Whenever particular defined terms of the Indenture not otherwise defined
herein are referred to, such defined terms are incorporated herein by reference.

GENERAL

         The Notes are, or will be,  secured  unsubordinated  obligations of the
Issuer, initially limited to $265.0 million aggregate principal amount, and will
mature on May 1, 2007.  Each Note will bear interest at the rate of 13 1/4% from
the Closing Date or from the most recent Interest Payment Date to which interest
has been paid or provided for, payable semiannually (to Holders of record at the
close of  business  on the April 15 or  October  15  immediately  preceding  the
Interest Payment Date) on May 1 and November 1 of each year, commencing November
1, 1997.

         Principal  of,  premium,  if any,  and  interest  on the Notes  will be
payable, and the Notes may be exchanged or transferred,  at the office or agency
of the Issuer in the Borough of Manhattan, The City of New York (which initially
will be the corporate  trust office of the Trustee at 114 West 47th Street,  New
York, New York 10036-1532);  provided that, at the option of the Issuer, payment
of  interest  may be made by check  mailed to the  respective  addresses  of the
Holders as each such address appears in the Security Register.

         The Notes are issued only in fully registered form, without coupons, in
denominations of $1,000 of principal amount and any integral  multiple  thereof.
See "--  Book-Entry;  Delivery and Form." No service charge will be made for any
registration  of  transfer  or  exchange  of Notes,  but the Issuer may  require
payment  of a sum  sufficient  to  cover  any  transfer  tax  or  other  similar
governmental charge payable in connection therewith.

         The  Issuer  may,  subject  to  the  covenants  described  below  under
"Covenants" and applicable law, issue additional Notes under the Indenture.  The
Notes  offered  hereby and any  additional  Notes  subsequently  issued would be
treated as a single class for all purposes under the Indenture.

STRUCTURE AND SECURITY

         The Indenture provided that on the Closing Date, GST Funding use all of
the net  proceeds  from the May  Offering  (in  addition to any cash on hand) to
purchase Pledged Securities and pledge the Pledged Securities to the Trustee for
the benefit of the  Holders of the Notes  pursuant  to a  Collateral  Pledge and
Security  Agreement (the "Pledge  Agreement")  dated as of the Closing Date from
GST Funding to United States Trust Company of New

                                      -68-

<PAGE>

York, as Trustee.  GST Funding acted in accordance  with such  provisions in the
Indenture and Pledge Agreement.  The Pledged Securities were pledged pursuant to
the Pledge Agreement and are held by the Trustee in the Pledge Account. Interest
earned  on the  Pledged  Securities  will be added  to the  Pledge  Account.  In
addition,  on the Closing  Date,  in  consideration  for GST Funding  making the
financing  through  the May  Offering  available  to GST USA and for GST Funding
facilitating the purchase of GST USA's equipment,  GST USA has agreed to pay any
fees or expenses incurred by GST Funding in connection  therewith and in support
of such  obligations  GST USA issued to GST  Funding a $35.0  million  principal
amount  promissory note (the "Initial Note") guaranteed by GST. The Initial Note
will mature on May 13, 2000 and there will not be any payment of interest  prior
to maturity.

         On the Closing Date,  GST Funding used  approximately  $41.5 million of
the net proceeds of the May Offering to refinance intercompany  indebtedness and
approximately  $93.8 million of the net proceeds of the May Offering to purchase
Pledged  Securities  to fund the first six  scheduled  interest  payments on the
Notes (the "Interest  Collateral").  GST Funding used the remaining net proceeds
of the May Offering to purchase Pledged  Securities  which, upon written request
from GST  Funding  to the  Trustee,  pledged  securities  (other  than  Interest
Collateral)  were or will be released from the Pledge  Account to GST Funding in
order to finance the cost (including,  without  limitation,  the cost of design,
development,    construction,    acquisition,   installation   or   integration)
(collectively,  "Acquired  Equipment Cost") of  telecommunications  inventory or
equipment  purchased  or  leased  by GST  Funding  ("Acquired  Equipment").  The
Acquired Equipment primarily will consist of fiber optic cable, digital switches
and digital  automatic  cross connect  equipment.  The release of amounts to GST
Funding in order to finance  Acquired  Equipment  Costs will occur  concurrently
with the expenditure of funds by GST Funding with respect to such costs and will
be in an  amount  equal  to such  costs.  Immediately  upon the  acquisition  of
Acquired Equipment, GST Funding must grant a first priority security interest in
such  Acquired  Equipment  to the  Trustee for the benefit of the Holders of the
Notes.  GST USA must  purchase  all  Acquired  Equipment  from GST  Funding at a
purchase price equal to the Acquired  Equipment Cost for such Acquired Equipment
and the purchase price shall be paid in the form of an  unsubordinated,  secured
promissory  note (an  "Intercompany  Note") in a principal  amount  equal to the
Acquired  Equipment  Cost,  issued  by GST USA  and  fully  and  unconditionally
guaranteed by GST. Each Intercompany Note will mature on May 13, 2000.  Interest
on each Intercompany Note will accrue at 15 1/4% compounded semiannually on each
May 1 and  November 1, but will not be payable in cash until the maturity of the
Intercompany  Note. Each  Intercompany  Note will be secured by a first priority
security  interest  in  all  Acquired  Equipment   purchased  by  GST  USA.  The
Intercompany  Notes will be prepaid if the maturity of the Notes is  accelerated
because  an Event of  Default  has  occurred  with  respect  to the Notes or the
payment of  principal,  premium or  interest on the Notes is  otherwise  due and
payable.  GST Funding  shall  grant a first  priority  security  interest in the
Pledged  Securities,  the Pledge Account,  the Initial Note and all Intercompany
Notes to the  Trustee  for the  benefit  of the  Holders  of the Notes to secure
repayment of the  principal  of,  premium and interest on the Notes.  On May 13,
2000, or earlier if permitted under the 1995 Indentures, GST USA will assume and
become the  direct  obligor  on the  Notes,  GST will fully and  unconditionally
guarantee  the  Notes on an  unsubordinated  basis,GST  USA  will  grant a first
priority  security  interest in all  Acquired  Equipment  to the Trustee for the
benefit of the Holders of the Notes and GST Funding will be  liquidated  and its
assets distributed to GST USA.

MANDATORY REDEMPTION

         If on May 13, 2000 GST USA is  prohibited by the 1995  Indentures  from
assuming all of the Notes,  GST Funding  will redeem,  upon not less than 10 nor
more than 30 days'  notice,  the  portion of the Notes that cannot be assumed at
101% of their  principal  amount plus accrued and unpaid interest to the date of
redemption.  In the event that the New Notes were required to be redeemed due to
a mandatory redemption or repurchased due to a Change of Control and GST Funding
is unable to redeem or repurchase the New Notes,  as the case may be, the result
would  be  a  default  under  the  Indenture.   Such  default  would  result  in
cross-defaults under the 1995 Indentures,  the Tomen Facility,  the Siemens Loan
Agreement and the NTFC Loan Agreement and the  indebtedness  thereunder would be
accelerated.  As of June 30, 1997,  $221.1 million  accreted value of 1995 Notes
was  outstanding  and the  Company had  incurred  $32.3  million of  outstanding
indebtedness under the Tomen Facility, $4.5 million of outstanding  indebtedness
under the Siemens Loan  Agreement  and $44.6 million of  indebtedness  under the
NTFC Loan  Agreement.  If such a default were to occur prior to the time GST USA
becomes a direct obligor on the New Notes,

                                      -69-

the sole  obligor  thereunder  would be GST  Funding,  which will have no assets
other than the collateral  securing the Notes.  Upon foreclosure after a default
upon the Notes,  such  collateral may not be sufficient to repay all amounts due
on the Notes.  If such a default were to occur after the time GST USA becomes an
obligor on the Notes, such default would permit the holders of substantially all
of the Company's indebtedness to accelerate the maturity thereof.

OPTIONAL REDEMPTION

         The Notes will be redeemable  at the option of the Issuer,  in whole or
in part,  at any time or from time to time, on or after May 1, 2002 and prior to
maturity,  upon not less than 30 nor more than 60 days' prior  notice  mailed by
first-class  mail to each  Holder's  last  address as it appears in the Security
Register,  at the  following  Redemption  Prices  (expressed in  percentages  of
principal  amount),  plus accrued and unpaid interest  thereon to the Redemption
Date (subject to the right of Holders of record on the relevant  Regular  Record
Date that is on or prior to the  Redemption  Date to receive  interest due on an
Interest Payment Date), if redeemed during the 12-month period  commencing May 1
of the years set forth below:

                    YEAR                                  REDEMPTION PRICE
                    ----                                  ----------------

                    2002..................................   106.6250%

                    2003..................................   103.3125%

                    2004 and thereafter...................    100.0000%

         In the case of any  partial  redemption,  selection  of the  Notes  for
redemption  will be made by the Trustee on a pro rata  basis,  by lot or by such
other  method as the  Trustee in its sole  discretion  shall deem to be fair and
appropriate;  provided that no Note of $1,000 in principal  amount or less shall
be redeemed in part.  If any Note is to be redeemed in part only,  the notice of
redemption relating to such Note shall state the portion of the principal amount
thereof to be redeemed.  A new Note in principal  amount equal to the unredeemed
portion  thereof  will  be  issued  in the  name  of  the  Holder  thereof  upon
cancellation of the original Note.

         The Notes  will also be subject to  redemption  as a whole,  but not in
part,  at the option of GST, at any time after GST USA has become the obligor on
the Notes and GST has guaranteed the Notes, at 100% of their  principal  amount,
together with accrued interest thereon, to the Redemption Date, in the event GST
has  become  or would  become  obligated  to pay,  on the next date on which any
amount  would be payable  with  respect to the Note  Guarantee,  any  Additional
Amounts  as a  result  of a  change  in  the  laws  (including  any  regulations
promulgated  thereunder)  of  Canada  (or any  political  subdivision  or taxing
authority thereof or therein),  or any change in any official position regarding
the application or interpretation  of such laws or regulations,  which change is
announced or becomes effective on or after the date of this Prospectus.

GUARANTEE

         GST  USA's  obligations  under  the  Notes,  the  Initial  Note and the
Intercompany  Notes  will  be  fully  and   unconditionally   guaranteed  on  an
unsubordinated basis by GST (collectively,  the "Note Guarantee").  However, the
Note Guarantee  shall not be  enforceable  against GST in an amount in excess of
the net worth of GST at the time that  determination of such net worth is, under
applicable law, relevant to the enforceability of such Note Guarantee.  Such net
worth shall include any claim of GST against GST USA for  reimbursement  and any
claim against any other guarantor for contribution.

                                      -70-

<PAGE>
RANKING

         The Notes are or will be secured,  unsubordinated  indebtedness  of the
Issuer.  The Note Guarantee will be unsecured,  unsubordinated  indebtedness  of
GST, will rank pari passu in right of payment with all unsecured, unsubordinated
indebtedness,  and  will be  senior  in  right of  payment  to all  subordinated
indebtedness,  of GST,  including the Convertible Notes. After GST USA becomes a
direct  obligor on the Notes on May 13, 2000, or earlier if permitted  under the
1995  Indentures,   the  Notes  and  the  Note  Guarantee  will  be  effectively
subordinated  to  all  liabilities  (including  trade  payables)  of  GST  USA's
subsidiaries.  At June 30,  1997,  (i) GST  USA's  subsidiaries  other  than GST
Funding had $114.4 million of  liabilities  (excluding  intercompany  payables),
including $90.5 million of indebtedness and (ii) GST's  subsidiaries  other than
GST USA and its subsidiaries  (including GST Funding),  had  approximately  $8.8
million of liabilities (excluding intercompany payables), including $2.4 million
of  indebtedness.  After GST USA  becomes a direct  obligor  on the Notes in the
event  the  holders  of the Notes or the  Trustee  foreclose  on the  collateral
securing the Notes and such  collateral is  insufficient  to pay all amounts due
with  respect to the  Notes,  the  holders  of the Notes will have an  unsecured
unsubordinated  claim for the amount still owing with respect to the Notes.  See
"Risk Factors -- Substantial  Indebtedness,"  "-- Possible  Inability to Service
Indebtedness,"  "--Insufficiency of Acquired Equipment to Satisfy the Notes upon
Liquidation,"   "--  Structure  of  GST  Funding,   GST  USA  and  GST;  Secured
Indebtedness;  Ranking of Notes," and  "Description of Certain  Indebtedness and
Redeemable Preferred Shares." Prior to the time GST USA becomes a direct obligor
on the Notes, in the event the holders of the Notes or the Trustee  foreclose on
the collateral securing the Notes and such collateral is insufficient to pay all
amounts due on the Notes,  the Holders will not have a claim  against GST USA or
GST  under the  Notes or the Note  Guarantee.  See  "Risk  Factors  --  Possible
Inability of GST USA to Assume and GST to Guarantee the Notes."

subordinated   to,  the  Subsidiary   Guarantee  or  (B)   subordinated  to  the
Intercompany Notes, the Notes or the Note Guarantee,  then the Guarantee of such
Guaranteed  Indebtedness  shall be subordinated  to the Subsidiary  Guarantee at
least to the extent that the  Guaranteed  Indebtedness  is  subordinated  to the
Intercompany Notes, the Notes or Note Guarantee, as the case may be.

transaction is pursuant to a written agreement,  at the time of the execution of
the agreement providing therefor, in a comparable arm's-length  transaction with
a Person that is not such a holder or an Affiliate.

to use  for  substantially  the  same  purpose  or  purposes  as the  assets  or
properties sold or transferred.

         The  foregoing   restriction  does  not  apply  to  any  sale-leaseback
transaction if (i) the lease is for a period,  including  renewal rights, of not
in excess of three  years;  (ii) the lease  secures  or  relates  to  industrial
revenue or pollution control bonds;  (iii) the transaction is solely between GST
and any Wholly  Owned  Restricted  Subsidiary  or solely  between  Wholly  Owned
Restricted  Subsidiaries;  or (iv) GST or such Restricted Subsidiary,  within 12
months  after the sale or transfer  of any assets or  properties  is  completed,
applies  an amount  not less than the net  proceeds  received  from such sale in
accordance  with clause (A) or (B) of the first  paragraph of the "Limitation on
Asset Sales" covenant described below.

         GST Funding will not, and will not permit any Subsidiary to, enter into
any sale-leaseback transaction.

         LIMITATION ON INVESTMENTS

         GST will not,  and will not permit any  Restricted  Subsidiary  to, (i)
make any Investment in any Person  (including an Unrestricted  Subsidiary)  that
during its most  recent  fiscal year  derived or in its  current  fiscal year is
expected  by the Board of  Directors  of GST to derive  more  than  $250,000  in
revenues  from, or in its most recent fiscal year spent or in its current fiscal
year is expected by the Board of  Directors  of GST to spend more than  $250,000
on,  operations  or activities  located  outside the  continental  United States
(other than in the State of Hawaii or between the continental  United States and
the State of  Hawaii)  (an  "International  Business")  or (ii)  acquire  or own
(directly or  indirectly),  other than through an Unrestricted  Subsidiary,  any
entity,  business or asset that is  primarily  located  outside the  continental
United  States  (other than in the State of Hawaii) or any right with respect to
any of the foregoing (an "International Asset").

         Notwithstanding  the  foregoing,  and  subject  to the  "Limitation  on
Restricted Payments" covenant,  GST and its Restricted  Subsidiaries may make an
Investment in an Unrestricted  Subsidiary which owns,  intends to acquire or has
rights with respect to an International Business or International Asset provided
that the aggregate  amount of such  Investments  does not exceed (i) $25 million
plus, (A) in any fiscal year, an amount not to exceed 10% of GST's  Consolidated
EBITDA (if positive) for the immediately preceding fiscal year and (B) an amount
not to exceed the Net Cash Proceeds  received by GST after the Closing Date from
the issuance and sale  permitted  by the  Indenture of its Capital  Stock (other
than Redeemable Stock) to a Person who is not a Subsidiary of GST, less (ii) the
amount of any Investments made pursuant to the first paragraph, or the amount of
any Restricted Payment made pursuant to clause (iii), (iv) or (vi) of the second
paragraph,  of the "Limitation on Restricted  Payments" covenant;  provided that
the  International  Business or International  Assets are related,  ancillary or
complementary to the primary business of GST and its Restricted  Subsidiaries on
the date of such Investment.

         LIMITATION ON ASSET SALES

         GST will  not,  and will  not  permit  any  Restricted  Subsidiary  to,
consummate any Asset Sale, unless (i) the consideration  received by GST or such
Restricted  Subsidiary  is at least equal to the fair market value of the assets
sold or disposed of and (ii) at least 85% of the consideration received consists
of cash or Temporary Cash Investments; provided, however, that clause (ii) shall
not apply to long-term assignments of capacity in a network. In the event and to
the  extent  that  the  Net  Cash  Proceeds  received  by GST or its  Restricted
Subsidiaries from one or more Asset Sales occurring on or after the Closing Date
in any period of 12 consecutive  months exceed 10% of Adjusted  Consolidated Net
Tangible Assets  (determined as of the date closest to the  commencement of such
12-month  period for which a  consolidated  balance  sheet of the Issuer and its
Subsidiaries  has been  prepared),  then GST shall or shall  cause the  relevant
Restricted  Subsidiary  to (i) within 12 months after the date Net Cash Proceeds
so received exceed 10% of Adjusted Consolidated Net Tangible Assets (A) apply an
amount   equal  to  such  excess  Net  Cash   Proceeds  to   permanently   repay
unsubordinated  Indebtedness of GST or GST USA or Indebtedness of any Restricted
Subsidiary  (other than GST USA),  in each case owing to a Person other than GST
or any of its Restricted

                                      -87-

<PAGE>

Subsidiaries  or (B)  invest  an equal  amount,  or the  amount  not so  applied
pursuant to clause (A) (or enter into a definitive  agreement  committing  to so
invest within 12 months after the date of such agreement), in property or assets
of a nature  or type or that  are used in a  business  (or in a  company  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,
GST 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 12-month  period  referred to in clause (i)) such excess Net Cash
Proceeds  (to the extent not applied  pursuant to clause (i)) as provided in the
following paragraph of this "Limitation on Asset Sales" covenant.  The amount of
such excess Net Cash  Proceeds  required to be applied (or to be committed to be
applied) during such 12-month period as set forth in clause (i) of 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 Offer to Purchase pursuant to this
"Limitation on Asset Sales"  covenant  totals at least $5.0 million,  the Issuer
must  commence,  not later than the  fifteenth  Business Day of such month,  and
consummate  an  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 101% of the principal amount of the Notes, plus, in
each case, accrued interest to the Payment Date.

         GST Funding will not, and will not permit any Subsidiary to, consummate
any Asset Sale except as permitted under the Pledge Agreement.

         IMPAIRMENT OF SECURITY INTERESTS OR ABILITY TO ASSUME THE NOTES

         The Indenture provides that none of GST, GST USA nor GST Funding shall,
nor shall they  permit any  Subsidiary  to, take or  knowingly  omit to take any
action  which (i) might or would have the  result of  materially  impairing  the
security  interest  with  respect  to  the  Pledged  Securities,   any  Acquired
Equipment, the Initial Note or Intercompany Notes for the benefit of the Trustee
and the Holders of the Notes, (ii) grant to any Person other than the Trustee or
the Holders of the Notes,  any interest  whatsoever  in the Pledged  Securities,
other amounts in the Pledge Account, any Acquired Equipment, the Initial Note or
any Intercompany Note or (iii) would prevent, or restrict GST USA from assuming,
or GST from  guaranteeing,  the Notes on May 13, 2000 or earlier if permitted by
the 1995 Indentures.

   
         REPURCHASE OF NOTES  UPON A CHANGE OF CONTROL
    
         The Issuer must commence,  within 30 days of the occurrence of a Change
of Control,  and consummate an Offer to Purchase for all Notes then outstanding,
at a purchase price equal to 101% of the principal amount thereof,  plus accrued
interest  to the  Payment  Date.  Prior to the  mailing of the notice to Holders
commencing such Offer to Purchase, but in any event within 30 days following any
Change of Control, the Issuer covenants to (i) repay in full all indebtedness of
the Issuer that would  prohibit  the  repurchase  of the Notes  pursuant to such
Offer to  Purchase  or (ii)  obtain any  requisite  consents  under  instruments
governing any such  indebtedness  of the Issuer to permit the  repurchase of the
Notes. The Issuer shall first comply with the covenant in the preceding sentence
before it shall  repurchase  Notes pursuant to this  "Repurchase of Notes upon a
Change of Control" covenant.

         Under the terms of the Indenture,  if the Issuer is unable to repay all
of its indebtedness that would prohibit  repurchase of the Notes or is unable to
obtain the  consents  of the  holders  of  indebtedness,  if any,  of the Issuer
outstanding  at the  time of a  Change  of  Control  whose  consent  would be so
required to permit the  repurchase  of Notes or otherwise  fails to purchase any
Notes,  then the Issuer  will have  breached  such  covenant.  This  breach will
constitute  an Event of Default under the Indenture if it continues for a period
of 30  consecutive  days  after  written  notice  is given to the  Issuer by the
Trustee or the  Holders  of at least 25% in  aggregate  principal  amount of the
Notes outstanding. In addition, the failure by the Issuer to repurchase Notes at
the  conclusion  of an Offer to  Purchase  will  constitute  an Event of Default
without any waiting period or notice requirements. In the event that

                                      -88-

<PAGE>
the New Notes were  required to be redeemed  due to a  mandatory  redemption  or
repurchased  due to a Change of Control  and GST  Funding is unable to redeem or
repurchase  the New Notes,  as the case may be,  the  result  would be a default
under the Indenture.  Such default would result in cross-defaults under the 1995
Indentures,  the Tomen  Facility,  the Siemens Loan  Agreement and the NTFC Loan
Agreement and the indebtedness  thereunder would be accelerated.  As of June 30,
1997,  $221.1  million  accreted  value of 1995 Notes were  outstanding  and the
Company had incurred $32.3 million of outstanding  indebtedness  under the Tomen
Facility,  $4.5  million of  outstanding  indebtedness  under the  Siemens  Loan
Agreement and $44.6 million of indebtedness  under the NTFC Loan  Agreement.  If
such a default were to occur prior to the time GST USA becomes a direct  obligor
on the New Notes, the sole obligor  thereunder would be GST Funding,  which will
have no assets other than the collateral  securing the Notes.  Upon  foreclosure
after a default upon the Notes,  such  collateral may not be sufficient to repay
all amounts due on the Notes. If such a default were to occur after the time GST
USA becomes an obligor on the Notes,  such  default  would permit the holders of
substantially  all of the  Company's  indebtedness  to  accelerate  the maturity
thereof.

         There can be no assurance  that the Issuer will have  sufficient  funds
available  at the  time of any  Change  of  Control  to make  any  debt  payment
(including  repurchases of Notes) required by the foregoing covenant (as well as
may be contained in other securities of the Issuer which might be outstanding at
the time). The above covenant requiring the Issuer to repurchase the Notes will,
unless the consents referred to above are obtained,  require the Issuer to repay
all indebtedness  then  outstanding  which by its terms would prohibit such Note
repurchase, either prior to or concurrently with such Note repurchase.

         COMMISSION REPORTS AND REPORTS TO HOLDERS

         At all  times  from  and  after  the  earlier  of (i)  the  date of the
commencement of an Exchange Offer or the effectiveness of the Shelf Registration
Statement  (the  "Registration")  and (ii) six months after the Closing Date, in
either  case,  whether or not GST Funding is then  required to file reports with
the Commission,  GST Funding shall file with the Commission all such reports and
other  information  as it would be  required  to file  with  the  Commission  by
Sections  13(a) or 15(d) under the Exchange Act if it were subject  thereto.  In
addition,  at all times prior to the earlier of the date of the Registration and
six months after the Closing Date, GST Funding shall,  at cost,  deliver to each
Holder of the Notes  quarterly and annual  reports  substantially  equivalent to
those which would be required by the  Exchange  Act. In  addition,  at all times
prior to the  Registration,  upon the  request of any Holder or any  prospective
purchaser of the Notes designated by a Holder,  GST Funding shall supply to such
Holder or such  prospective  purchaser the information  required under Rule 144A
under the  Securities  Act.  Whether or not GST is required to file reports with
the Commission, if any Notes are outstanding, GST shall file with the Commission
all such reports and other  information as it would be required to file with the
Commission  by Sections  13(a) or 15(d) under the Exchange  Act. GST Funding and
GST shall  supply the Trustee  and each  Holder of Notes or shall  supply to the
Trustee for  forwarding to each Holder,  without cost to such Holder,  copies of
such reports or other information.

EVENTS OF DEFAULT

         The following events are defined as "Events of Default": (a) default in
the payment of  principal  of (or  premium,  if any,  on) any Note when the same
becomes due and payable at maturity, upon acceleration, redemption or otherwise;
(b) default in the payment of interest on any Note when the same becomes due and
payable,  and such default  continues  for a period of 30 days;  provided that a
failure to make any of the first six scheduled interest payments on the Notes on
the applicable Interest Payment Date will constitute an Event of Default with no
grace  or  cure  period;  (c)  GST,  GST  USA or  GST  Funding  defaults  in the
performance  of or breaches any other  covenant or agreement in the Indenture or
under the Notes, the Note Guarantee,  the Initial Note or the Intercompany Notes
and such default or breach  continues for a period of 30 consecutive  days after
written  notice  by the  Trustee  or the  Holders  of 25% or more  in  aggregate
principal  amount of Notes; (d) there occurs with respect to any issue or issues
of  Indebtedness  of GST or any  Significant  Subsidiary  having an  outstanding
principal  amount of $5 million or more in the  aggregate for all such issues of
all such Persons, whether such Indebtedness now exists or shall hereafter be

                                      -89-

<PAGE>

created,  (I) an event of default that has caused the holder  thereof to declare
such  Indebtedness  to be due and payable prior to its Stated  Maturity and such
Indebtedness  has not been discharged in full or such  acceleration has not been
rescinded  or  annulled  within  30 days of such  acceleration  and/or  (II) the
failure to make a  principal  payment at the final (but not any  interim)  fixed
maturity and such defaulted payment shall not have been made, waived or extended
within 30 days of such  payment  default;  (e) any final  judgment or order (not
covered by  insurance)  for the  payment of money in excess of $5 million in the
aggregate  for all such  final  judgments  or orders  against  all such  Persons
(treating any deductibles,  self-insurance or retention as not so covered) shall
be rendered against GST, GST USA, GST Funding or any Significant  Subsidiary and
shall not be paid or discharged, and there shall be any period of 30 consecutive
days  following  entry of the final  judgment or order that causes the aggregate
amount  for all such  final  judgments  or  orders  outstanding  and not paid or
discharged  against all such Persons to exceed $5 million during which a stay of
enforcement  of such final  judgment or order,  by reason of a pending appeal or
otherwise,  shall  not be in  effect;  (f) a court  having  jurisdiction  in the
premises enters a decree or order for (A) relief in respect of GST, GST USA, GST
Funding  or  any  Significant  Subsidiary  in  an  involuntary  case  under  any
applicable  bankruptcy,  insolvency  or other  similar law now or  hereafter  in
effect, (B) appointment of a receiver, liquidator, assignee, custodian, trustee,
sequestrator or similar official of GST, GST USA, GST Funding or any Significant
Subsidiary  (other than a liquidation  of GST Funding into GST USA in connection
with  the  assumption  of the  Notes)  or for  all or  substantially  all of the
property and assets of GST, GST USA, GST Funding or any  Significant  Subsidiary
or (C) the winding up or liquidation of the affairs of GST, GST USA, GST Funding
or any Significant  Subsidiary (other than a liquidation of GST Funding into GST
USA in  connection  with the  assumption  of the Notes) and, in each case,  such
decree  or  order  shall  remain  unstayed  and in  effect  for a  period  of 30
consecutive  days; (g) GST, GST USA, GST Funding or any  Significant  Subsidiary
(A) commences a voluntary  case under any applicable  bankruptcy,  insolvency or
other  similar law now or  hereafter  in effect,  or consents to the entry of an
order for relief in an involuntary  case under any such law, (B) consents to the
appointment  of  or  taking  possession  by a  receiver,  liquidator,  assignee,
custodian,  trustee,  sequestrator  or similar  official  of GST,  GST USA,  GST
Funding or any Significant  Subsidiary  (other than a liquidation of GST Funding
into GST USA in  connection  with the  assumption  of the  Notes)  or for all or
substantially all of the property and assets of GST, GST USA, GST Funding or any
Significant  Subsidiary or (C) effects any general assignment for the benefit of
creditors;  (h) the  Trustee or GST  Funding  does not have at all times a first
priority  perfected  security  interest  in all Pledged  Securities,  the Pledge
Account, all Acquired Equipment, the Initial Note and Intercompany Notes or GST,
GST USA or GST Funding asserts in writing that the security  arrangements  under
the Indenture,  the Pledge Account,  the Initial Note and the Intercompany Notes
are not in full force and effect;  or (i) GST USA shall not have become a direct
obligor  on the Notes  (other  than  Notes to be  redeemed  as  described  under
"Mandatory Redemption" for which GST Funding shall have deposited the redemption
price) and GST shall not have become a guarantor of the Notes by May 13, 2000.

         If an Event of Default  (other  than an Event of Default  specified  in
clause (f) or (g) above that occurs with  respect to GST USA, GST or GST Funding
or clause (h) above) occurs and is continuing  under the Indenture,  the Trustee
or the Holders of at least 25% in aggregate  principal amount of the outstanding
Notes,  by written  notice to the Issuer  (and to the  Trustee if such notice is
given by the  Holders),  may,  and the  Trustee at the  request of such  Holders
shall,  declare the principal of, premium, if any, and accrued interest,  on the
Notes to be immediately  due and payable.  Upon a declaration  of  acceleration,
such principal,  premium,  if any, and accrued interest shall be immediately due
and payable.  In the event of a declaration of acceleration  because an Event of
Default  set forth in clause  (d) above has  occurred  and is  continuing,  such
declaration of acceleration shall be automatically rescinded and annulled if the
event of default  triggering such Event of Default  pursuant to clause (d) shall
be remedied or cured by GST or the relevant Significant  Subsidiary or waived by
the holders of the relevant Indebtedness within 60 days after the declaration of
acceleration  with respect thereto.  If an Event of Default  specified in clause
(f) or (g) above occurs with respect to GST USA, GST, or GST Funding or an Event
of Default  specified in clause (h) occurs,  the principal of, premium,  if any,
and accrued interest,  on the Notes then outstanding 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.  The Holders of at least a majority in  principal
amount of the  outstanding  Notes by  written  notice to the  Issuer  and to the
Trustee,  may waive all past  Defaults  and rescind and annul a  declaration  of
acceleration and its  consequences if (i) all existing Events of Default,  other
than the  nonpayment of the principal of,  premium,  if any, and interest on the
Notes that have become due solely by such declaration of acceleration, have been
cured or

                                      -90-

<PAGE>

waived and (ii) the rescission would not conflict with any judgment or decree of
a court of competent jurisdiction. For information as to the waiver of defaults,
see "--Modification and Waiver."

         The Holders of at least a majority in aggregate principal amount of the
outstanding  Notes may  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.  However,  the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the Trustee
in  personal  liability,  or that the  Trustee  determines  in good faith may be
unduly  prejudicial  to the rights of Holders of Notes not joining in the giving
of such  direction  and may take any other  action it deems  proper  that is not
inconsistent  with any such  direction  received from Holders of Notes. A Holder
may not pursue any remedy with respect to the Indenture or the Notes unless: (i)
the Holder gives the Trustee  written  notice of a continuing  Event of Default;
(ii) the Holders of at least 25% in aggregate  principal  amount of  outstanding
Notes make a written  request to the  Trustee to pursue the  remedy;  (iii) such
Holder or  Holders  offer and,  if  requested  provide,  the  Trustee  indemnity
satisfactory  to the Trustee against any costs,  liability or expense;  (iv) the
Trustee  does not comply  with the request  within 60 days after  receipt of the
request  and the offer of  indemnity;  and (v) during such  60-day  period,  the
Holders of a majority in aggregate  principal amount of the outstanding Notes do
not give the Trustee a direction that is inconsistent with the request. However,
such  limitations  do not apply to the right of any  Holder of a Note to receive
payment of the  principal of,  premium,  if any, or interest on, such Note or to
bring suit for the  enforcement  of any such  payment,  on or after the due date
expressed  in the Notes,  which right shall not be impaired or affected  without
the consent of the Holder.

         The Indenture requires certain officers of the Issuer to certify, on or
before a date not more than 90 days after the end of each  fiscal  year,  that a
review has been  conducted of the  activities  of GST  Funding,  GST and GST USA
under the  Indenture  and that GST Funding,  GST and GST USA have  fulfilled all
obligations  thereunder,  or, if there has been a default in the  fulfillment of
any such  obligation,  specifying  each such  default  and the nature and status
thereof.  The Issuer will also be obligated to notify the Trustee of any default
or  defaults  in the  performance  of any  covenants  or  agreements  under  the
Indenture.

CONSOLIDATION, MERGER AND SALE OF ASSETS

         Under  the  terms  of the  Indenture,  neither  GST nor  GST USA  shall
consolidate  with,  merge  with or into,  or sell,  convey,  transfer,  lease or
otherwise  dispose of all or substantially all of its property and assets (as an
entirety or  substantially an entirety in one transaction or a series of related
transactions)  to, any Person (other than a consolidation or merger with or into
a Wholly Owned Restricted  Subsidiary with a positive net worth;  provided that,
in connection with any such merger or  consolidation,  no  consideration  (other
than Common Stock in the  surviving  Person,  GST or GST USA) shall be issued or
distributed to the stockholders of GST or GST USA) or permit any Person to merge
with or into GST or GST USA unless:  (i) GST or GST USA shall be the  continuing
Person,  or  the  Person  (if  other  than  GST  or  GST  USA)  formed  by  such
consolidation  or into which GST or GST USA is merged or that acquired or leased
such property and assets of GST or GST USA shall be a corporation  organized and
validly  existing  under  the  laws  of the  United  States  of  America  or any
jurisdiction  thereof and shall expressly assume,  by a supplemental  indenture,
executed and delivered to the Trustee, all of the obligations of GST or GST USA,
on all of the Notes, the Intercompany Notes and the Note Guarantee and under the
Indenture; (ii) immediately after giving effect to such transaction,  no Default
or Event of Default shall have  occurred and be  continuing;  (iii)  immediately
after giving effect to such  transaction on a pro forma basis, GST or GST USA or
any Person becoming the successor obligor of the Notes or the Note Guarantee, as
the case may be,  shall have a  Consolidated  Net Worth equal to or greater than
the  Consolidated  Net Worth of GST or GST USA, as the case may be,  immediately
prior  to  such  transaction;  (iv)  immediately  after  giving  effect  to such
transaction  on a pro  forma  basis  GST or GST USA,  as the case may be, or any
Person becoming the successor obligor of the Notes or the Note Guarantee, as the
case may be,  could  Incur  at  least  $1.00 of  Indebtedness  under  the  first
paragraph of the "Limitation on Indebtedness"  covenant; and (v) GST or GST USA,
as the case may be, delivers to the Trustee an Officers' Certificate  (attaching
the arithmetic  computations  to demonstrate  compliance  with clauses (iii) and
(iv)) and  Opinion of Counsel,  in each case  stating  that such  consolidation,
merger or transfer and such supplemental  indenture complies with this provision
and all conditions precedent provided for herein relating to such transaction

                                      -91-

<PAGE>

have been complied with; provided, however, that clauses (iii) and (iv) above do
not apply if, in the good faith  determination  of the Board of Directors of GST
or GST USA, as the case may be,  whose  determination  shall be  evidenced  by a
Board  Resolution,  the principal  purpose of such  transaction is to change the
jurisdiction of  incorporation  of GST to a state of the United States or of GST
USA to another state of the United  States;  and provided  further that any such
transaction  shall not have as one of its purposes the evasion of the  foregoing
limitations.

         The  restrictions and conditions  described in the preceding  paragraph
also apply to GST Funding  except that clauses  (iii) and (iv) do not apply to a
merger or  consolidation  of GST USA and GST Funding or the sale,  conveyance or
other  disposition of all or  substantially  all of the assets of GST Funding to
GST USA.

DEFEASANCE

         Defeasance and Discharge.  The Indenture  provides that the Issuer will
be deemed to have paid and GST, GST USA and GST Funding will be discharged  from
any and all  obligations  in  respect  of the  Notes on the  123rd day after the
deposit referred to below, and the provisions of the Indenture will no longer be
in effect with respect to the Notes (except for,  among other  matters,  certain
obligations to register the transfer or exchange of the Notes to replace stolen,
lost or  mutilated  Notes,  to maintain  paying  agencies and to hold monies for
payment in trust) if, among other things,  (A) the Issuer has deposited with the
Trustee,  in trust,  money and/or U.S.  Government  Obligations that through the
payment of interest and principal in respect  thereof in  accordance  with their
terms  will  provide  money in an amount  sufficient  to pay the  principal  of,
premium,  if any,  and accrued  interest on the Notes on the Stated  Maturity of
such payments in accordance  with the terms of the Indenture and the Notes,  (B)
the Issuer has  delivered to the Trustee (i) either (x) an Opinion of Counsel to
the effect  that  Holders  will not  recognize  income,  gain or loss for United
States federal  income tax purposes as a result of the Issuer's  exercise of its
option under this  "Defeasance"  provision  and will be subject to United States
federal  income tax on the same amount and in the same manner as would have been
the case if such deposit,  defeasance  and  discharge  had not  occurred,  which
Opinion of Counsel must be based upon (and accompanied by a copy of) a ruling of
the  Service to the same  effect  unless  there has been a change in  applicable
United States  federal  income tax law after the Closing Date such that a ruling
is no longer required or (y) a ruling directed to the Trustee  received from the
Service to the same effect as the  aforementioned  Opinion of  Counsel;  (ii) an
Opinion of Counsel or a ruling from Revenue Canada,  Customs,  Excise & Taxation
to the effect that Holders will not recognize income,  gain or loss for Canadian
federal,  provincial or territorial income tax or other tax purposes as a result
of such  deposit  and  defeasance  and will be  subject to  Canadian  federal or
provincial income tax and other tax on the same amounts,  in the same manner and
at the same times as would have been the case had such  deposit  and  defeasance
not occurred  (and for purposes of such  opinion,  such  Canadian  counsel shall
assume  that  Holders  of the Notes  include  Holders  who are not  resident  in
Canada);  and (iii) an Opinion of Counsel to the effect that the creation of the
defeasance  trust does not violate the Investment  Company Act of 1940 and after
the  passage  of 123 days  following  the  deposit,  the trust  fund will not be
subject to the effect of Section  547 of the United  States  Bankruptcy  Code or
Section 15 of the New York Debtor and Creditor Law, (C) immediately after giving
effect to such deposit on a pro forma basis, no Event of Default,  or event that
after the  giving of  notice or lapse of time or both  would  become an Event of
Default,  shall have  occurred and be  continuing on the date of such deposit or
during the period  ending on the 123rd day after the date of such  deposit,  and
such  deposit  shall not result in a breach or  violation  of, or  constitute  a
default under,  any other  agreement or instrument to which the Issuer or any of
its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is
bound  and (D) if at such time the Notes  are  listed on a  national  securities
exchange,  the Issuer has  delivered to the Trustee an Opinion of Counsel to the
effect  that  the  Notes  will not be  delisted  as a  result  of such  deposit,
defeasance and discharge.

         Defeasance  of Certain  Covenants  and Certain  Events of Default.  The
Indenture  further provides that its provisions will no longer be in effect with
respect  to  clauses  (iii) and (iv)  under  "Consolidation,  Merger and Sale of
Assets" and all the covenants  described  herein under  "Covenants,"  clause (c)
under "Events of Default"  with respect to such  covenants and clauses (iii) and
(iv) under "Consolidation,  Merger and Sale of Assets," and clauses (d), (e) and
(h) under "Events of Default"  shall be deemed not to be Events of Default upon,
among other things,

                                      -92-

the  deposit  with the  Trustee,  in  trust,  of money  and/or  U.S.  Government
Obligations  that  through  the  payment of interest  and  principal  in respect
thereof  in  accordance  with  their  terms  will  provide  money  in an  amount
sufficient to pay the principal of, premium, if any, and accrued interest on the
Notes on the Stated  Maturity of such payments in  accordance  with the terms of
the Indenture and the Notes,  the  satisfaction  of the provisions  described in
clauses B(iii),  (C) and (D) of the preceding  paragraph and the delivery by the
Issuer to the Trustee of an Opinion of Counsel to the effect  that,  among other
things,  the Holders will not recognize  income,  gain or loss for United States
federal  income tax  purposes or Canadian  federal,  provincial  or  territorial
income tax or other tax purposes as a result of such deposit and  defeasance  of
certain  covenants  and Events of Default  and will be subject to United  States
federal  income tax and Canadian  federal or  provincial  income tax on the same
amount and in the same  manner and at the same times as would have been the case
if such deposit and defeasance had not occurred.

         Defeasance and Certain Other Events of Default. In the event the Issuer
exercises its option to omit compliance with certain covenants and provisions of
the  Indenture  with  respect  to the  Notes  as  described  in the  immediately
preceding  paragraph  and the Notes are declared due and payable  because of the
occurrence of an Event of Default that remains  applicable,  the amount of money
and/or  U.S.  Government  Obligations  on  deposit  with  the  Trustee  will  be
sufficient to pay amounts due on the Notes at the time of their Stated  Maturity
but may not be  sufficient  to pay  amounts  due on the Notes at the time of the
acceleration  resulting  from such Event of  Default.  However,  the Issuer will
remain liable for such payments.

MODIFICATION AND WAIVER

         Modifications  and  amendments of the Indenture may be made by GST, GST
USA and GST Funding and the Trustee  with the consent of the Holders of not less
than  a  majority  in  aggregate  principal  amount  of the  outstanding  Notes;
provided,  however,  that no such  modification  or amendment  may,  without the
consent of each Holder affected  thereby,  (i) change the Stated Maturity of the
principal  of, or any  installment  of  interest  on, any Note,  (ii) reduce the
principal  of, or premium,  if any, or interest  on, any Note,  (iii) change the
place or currency of payment of  principal  of, or premium,  if any, or interest
on, any Note, (iv) impair the right to institute suit for the enforcement of any
payment on or after the Stated Maturity (or, in the case of a redemption,  on or
after the Redemption Date) of any Note, (v) reduce the  above-stated  percentage
of  outstanding  Notes the consent of whose  Holders is  necessary  to modify or
amend the  Indenture,  (vi) waive a default  in the  payment  of  principal  of,
premium,  if any, or interest on the Notes,  or (vii) reduce the  percentage  or
aggregate  principal amount of outstanding Notes the consent of whose Holders is
necessary for waiver of compliance  with certain  provisions of the Indenture or
for waiver of certain defaults.

         None of GST,  GST USA or GST  Funding  shall  amend,  modify,  alter or
supplement or permit or consent to any amendment, modification or supplement of,
the Pledge Agreement, the Initial Note or any Intercompany Notes in any way that
would be adverse to the Holders of the Notes.

ADDITIONAL AMOUNTS

         Any payments made by GST under or with respect to the Notes pursuant to
the Note  Guarantee  will be made free and clear of and without  withholding  or
deduction for or on account of any present or future tax,  duty,  levy,  impost,
assessment or other governmental charge (including penalties, interest and other
liabilities related thereto) imposed or levied by or on behalf of the Government
of Canada or of any province or territory  thereof or by any authority or agency
therein or thereof  having power to tax  (hereinafter,  "Taxes"),  unless GST is
required  to  withhold  or  deduct  Taxes  by law or by  the  interpretation  or
administration  thereof. If GST is required to withhold or deduct any amount for
or on account of Taxes from any payment made under or with respect to the Notes,
GST will pay such additional amounts ("Additional Amounts") as may be necessary,
so that the net amount  received by each Holder of Notes  (including  Additional
Amounts)  after such  withholding  or deduction will not be less than the amount
such Holder would have received if such Taxes had not been withheld or deducted;
provided,  however, that no Additional Amounts will be payable with respect to a
payment made to a Holder (an "Excluded Holder") (i) with which GST does not deal
at arm's length  (within the meaning of the Income Tax Act (Canada)) at the time
of

                                      -93-

<PAGE>

making  such  payment,  or (ii)  which is subject to such Taxes by reason of its
being connected with Canada or any province or territory  thereof otherwise than
solely by reason of the Holder's  activity in  connection  with  purchasing  the
Notes,  by the mere  holding of Notes or by reason of the  receipt  of  payments
thereunder. GST will, upon written request of any Holder (other than an Excluded
Holder),  reimburse  such  Holder,  for the amount of (i) any Taxes so levied or
imposed  and paid by such  Holder as a result  of  payments  made  under or with
respect to the Notes and (ii) any Taxes so levied or imposed with respect to any
reimbursement  under the  foregoing  clause (i), but excluding any such Taxes on
such  Holder's  net income so that the net amount  received by such Holder after
such  reimbursement  will not be less than the net amount the Holder  would have
received if Taxes on such reimbursement had not been imposed.

         At least 30 days prior to each date on which any payment  under or with
respect  to the  Notes  is due and  payable,  if GST  will be  obligated  to pay
Additional Amounts with respect to such payment, GST will deliver to the Trustee
an Officers'  Certificate  stating the fact that such Additional Amounts will be
payable  and the  amounts so payable  and will set forth such other  information
necessary to enable the Trustee to pay such Additional Amounts to Holders on the
payment date.  Whenever either in the Indenture or in this  Prospectus  there is
mentioned,  in any  context,  the payment of  principal  (or  premium,  if any),
Redemption Price,  interest or any other amount payable under or with respect to
the Notes,  such  mention  shall be deemed to include  mention of the payment of
Additional Amounts to the extent that, in such context,  Additional Amounts are,
were or would be payable in respect thereof.

         In the event that GST has become or would  become  obligated to pay, on
the next date on which any amount would be payable  under or with respect to the
Notes any Additional  Amounts as a result of certain changes affecting  Canadian
withholding  tax laws,  GST may redeem all,  but not less than all, the Notes at
any time at 100% of their  principal  amount,  together  with  accrued  interest
thereon to the redemption date. See "-- Optional Redemption."

CONSENT TO JURISDICTION AND SERVICE

         GST Funding,  GST and GST USA have  appointed  Olshan  Grundman Frome &
Rosenzweig  LLP,  505 Park Avenue,  New York,  New York 10022 as their agent for
service  of  process  in any suit,  action or  proceeding  with  respect  to the
Indenture  or the Notes  and for the  actions  brought  under  federal  or state
securities laws brought in any federal or state court located in The City of New
York and will agree to submit to the jurisdiction of such courts.

ENFORCEABILITY OF JUDGMENTS

         GST is  incorporated  in Canada.  Certain  directors and officers,  and
certain experts named herein,  are residents of Canada.  As a result,  it may be
difficult or  impossible to effect  service of process  within the United States
upon such  directors,  officers  and experts or to collect  judgments  of United
States courts  predicated  upon civil  liability under the United States federal
securities and other laws.  There are risks as to whether  Canadian courts would
(i) enforce  judgments  of United  States  courts  obtained  against GST or such
directors,  officers and experts predicated upon the civil liability  provisions
of United States laws or (ii) impose liabilities in original actions against GST
or its  directors,  officers and experts  predicated  solely upon United  States
securities laws.

BOOK-ENTRY; DELIVERY AND FORM

         The certificates  representing the Notes are issued in fully registered
form without interest coupons.  Notes sold in offshore  transactions in reliance
on Regulation S under the Securities Act will initially be represented by one or
more  temporary  global  Notes in  definitive,  fully  registered  form  without
interest  coupons  (each a  "Temporary  Regulation  S Global  Note") and will be
deposited  with the Trustee as custodian  for, and  registered  in the name of a
nominee of, DTC for the  accounts of  Euroclear  and Cedel Bank.  The  Temporary
Regulation S Global Note will be exchangeable  for one or more permanent  global
Notes (each a  "Permanent  Regulation  S Global  Note";  and  together  with the
Temporary Regulation S Global Notes, the "Regulation S Global Note") on or after
the 40th day following the Closing Date upon  certification  that the beneficial
interests in such global Note are owned by non-U.S.

                                      -94-

<PAGE>

persons.  Prior to the 40th day after the Closing Date,  beneficial interests in
the  Temporary  Regulation S Global Note may be held only  through  Euroclear or
Cedel Bank and any resale or other  transfer of such  interests to U.S.  persons
shall not be permitted during such period unless such resale or transfer is made
pursuant to Rule 144A or  Regulation S and in accordance  with the  requirements
described below.

         Notes sold in reliance on Rule 144A will be  represented by one or more
permanent  global Notes in definitive,  fully  registered form without  interest
coupons (each a "Restricted  Global  Note";  and together with the  Regulation S
Global  Note,  the  "Global  Notes") and will be  deposited  with the Trustee as
custodian for, and registered in the name of a nominee of, DTC.

         Each Global Note (and any Notes issued for exchange  therefor)  will be
subject to certain restrictions on transfer set forth therein as described under
"Transfer Restrictions."

         Notes   originally   purchased  by  or  transferred  to   Institutional
Accredited  Investors who are not qualified  institutional  buyers  ("Non-Global
Purchasers")  will be issued Notes in registered form without  interest  coupons
("Certificated Notes"). Upon the transfer of Certificated Notes initially issued
to a Non-Global  Purchaser to a qualified  institutional  buyer or in accordance
with Regulation S, such Certificated Notes will, unless the relevant Global Note
has previously been exchanged in whole for Certificated  Notes, be exchanged for
an interest in a Global  Note.  For a  description  of the  restrictions  on the
transfer of Certificated Notes, see "Transfer Restrictions."

         The Global Notes.  Ownership of  beneficial  interests in a Global Note
will be  limited to  persons  who have  accounts  with DTC  ("participants")  or
persons  who  hold  interests  through  participants.  Ownership  of  beneficial
interests in a Global Note will be shown on, and the transfer of that  ownership
will be effected  only through,  records  maintained by DTC or its nominee (with
respect to  interests of  participants)  and the records of  participants  (with
respect  to   interests   of  persons   other  than   participants).   Qualified
institutional  buyers may hold  their  interests  in a  Restricted  Global  Note
directly  through DTC if they are  participants  in such system,  or  indirectly
through organizations which are participants in such system.

         Investors  may hold  their  interests  in a  Regulation  S Global  Note
directly  through  Cedel Bank or  Euroclear,  if they are  participants  in such
systems,  or indirectly  through  organizations  that are  participants  in such
system.  Cedel Bank and Euroclear will hold interests in the Regulation S Global
Notes on behalf of their participants through DTC.

         So long as DTC, or its nominee,  is the registered owner or holder of a
Global Note,  DTC or such nominee,  as the case may be, will be  considered  the
sole  owner or holder  of the  Notes  represented  by such  Global  Note for all
purposes under the Indenture and the Notes.  No beneficial  owner of an interest
in a Global Note will be able to transfer  that  interest  except in  accordance
with the  applicable  procedures of DTC, in addition to those provided for under
the Indenture and, if applicable, those of Euroclear and Cedel Bank.

         Payments of the  principal  of, and  interest on, a Global Note will be
made to DTC or its nominee, as the case may be, as the registered owner thereof.
Neither   the  Issuer,   the  Trustee  nor  any  Paying   Agent  will  have  any
responsibility  or  liability  for any  aspect  of the  records  relating  to or
payments made on account of beneficial  ownership  interests in a Global Note or
for  maintaining,   supervising  or  reviewing  any  records  relating  to  such
beneficial ownership interests.

         The Issuer expects that DTC or its nominee, upon receipt of any payment
of principal or interest in respect of a Global Note, will credit  participants'
accounts with payments in amounts  proportionate to their respective  beneficial
interests in the principal amount of such Global Note as shown on the records of
DTC or its nominee.  The Issuer also expects that  payments by  participants  to
owners  of   beneficial   interests  in  such  Global  Note  held  through  such
participants will be governed by standing  instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in the  names  of  nominees  for  such  customers.  Such  payments  will  be the
responsibility of such participants.

                                      -95-

<PAGE>

         Transfers between  participants in DTC will be effected in the ordinary
way in  accordance  with  DTC  rules  and will be  settled  in  same-day  funds.
Transfers  between  participants in Euroclear and Cedel Bank will be effected in
the  ordinary  way in  accordance  with  their  respective  rules and  operating
procedures.

         The Issuer expects that DTC will take any action  permitted to be taken
by a holder  of Notes  (including  the  presentation  of Notes for  exchange  as
described  below) only at the  direction  of one or more  participants  to whose
account the DTC  interests  in a Global Note is credited  and only in respect of
such  portion  of the  aggregate  principal  amount  of Notes  as to which  such
participant or participants has or have given such direction.  However, if there
is an Event of Default under the Notes, DTC will exchange the applicable  Global
Note for  Certificated  Notes,  which it will distribute to its participants and
which may be legended as set forth under the heading "Transfer Restrictions."

         The Issuer  understands  that:  DTC is a limited  purpose trust company
organized  under  the laws of the State of New York,  a  "banking  organization"
within the  meaning of New York  Banking  Law, a member of the  Federal  Reserve
System, a "clearing  corporation"  within the meaning of the Uniform  Commercial
Code and a "Clearing  Agency"  registered  pursuant to the provisions of Section
17A  under  the  Exchange  Act.  DTC  was  created  to hold  securities  for its
participants   and   facilitate  the  clearance  and  settlement  of  securities
transactions  between  participants  through  electronic  book-entry  changes in
accounts of its participants, thereby eliminating the need for physical movement
of  certificates  and certain other  organizations.  Indirect  access to the DTC
system  is  available  to  others  such as  banks,  brokers,  dealers  and trust
companies  that  clear  through  or  maintain a  custodial  relationship  with a
participant, either directly or indirectly ("indirect participants").

         Although  DTC,  Euroclear  and Cedel  Bank are  expected  to follow the
foregoing  procedures in order to facilitate  transfers of interests in a Global
Note among  participants  of DTC,  Euroclear  and Cedel Bank,  they are under no
obligation  to  perform  or  continue  to  perform  such  procedures,  and  such
procedures may be discontinued  at any time.  Neither the Issuer nor the Trustee
will have any responsibility for the performance by DTC, Euroclear or Cedel Bank
or their  respective  participants or indirect  participants of their respective
obligations under the rules and procedures governing their operations.

CERTIFICATED NOTES

         If DTC is at any time  unwilling  or unable to continue as a depositary
for the Global Notes and a successor  depositary  is not appointed by the Issuer
within 90 days,  the Issuer will issue  Certificated  Notes,  which may bear the
legend  referred to under  "Transfer  Restrictions,"  in exchange for the Global
Notes.  Holders of an interest in a Global Note may receive  Certificated Notes,
which  may  bear  the  legend  referred  to under  "Transfer  Restrictions,"  in
accordance with the DTC's rules and procedures in addition to those provided for
under the Indenture.

NO PERSONAL  LIABILITY OF INCORPORATORS,  SHAREHOLDERS,  OFFICERS,  DIRECTORS OR
EMPLOYEES

         The  Indenture  provides  that  no  recourse  for  the  payment  of the
principal of, premium,  if any, or interest on any of the Notes or for any claim
based thereon or otherwise in respect thereof, and no recourse under or upon any
obligation,  covenant  or  agreement  of  GST,  GST  USA or GST  Funding  in the
Indenture, or in any of the Notes or because of the creation of any Indebtedness
represented  thereby,  shall  be  had  against  any  incorporator,  shareholder,
officer, director, employee or controlling person of GST, GST USA or GST Funding
or of any successor Person thereof.  Each Holder by accepting the Notes,  waives
and releases all such liability.

CONCERNING THE TRUSTEE

         The  Indenture  provides  that,  except  during  the  continuance  of a
Default,  the Trustee  will not be liable,  except for the  performance  of such
duties as are specifically  set forth in such Indenture.  If an Event of Default
has occurred and is continuing, the Trustee will use the same degree of care and
skill in its exercise as a prudent person would exercise under the circumstances
in the conduct of such person's own affairs.

                                      -96-

<PAGE>

         The Indenture and provisions of the Trust  Indenture Act,  incorporated
by reference therein contain limitations on the rights of the Trustee, should it
become a creditor of the Issuer, to obtain payment of claims in certain cases or
to realize on certain property  received by it in respect of any such claims, as
security or otherwise. The Trustee is permitted to engage in other transactions;
provided,  however,  that if the Trustee acquires any conflicting  interest,  it
must eliminate such conflict or resign.

       DESCRIPTION OF CERTAIN INDEBTEDNESS AND REDEEMABLE PREFERRED SHARES

TOMEN FACILITY

         The  following  summary of the  material  provisions  of the  documents
comprising  the Tomen  Facility.  Terms  used and not  defined  herein  have the
meanings given to them in the documents described herein.

         GENERAL

         The Company,  GST Telecom and Pacwest are parties to a Master Agreement
dated October 24, 1994 and amended May 24, 1996 (the "Tomen  Master  Agreement")
with  Tomen  pursuant  to  which  Tomen  agreed,  in its  sole  discretion  on a
project-by-project  basis,  to make available up to a total of $100.0 million of
financing for  telecommunications  network projects developed and constructed by
the  Company.  Under  the  terms of the Tomen  Master  Agreement,  Tomen has the
exclusive right to review the Company's  proposed  network  projects until Tomen
has extended $100.0 million in debt financing or has refused three projects that
the Company  subsequently  finances.  If Tomen approves a project it would enter
into a credit  agreement  (in  substantially  the form of the  Credit  Agreement
hereinafter described) with the subsidiary of the Company developing the project
(a "Development Company") to provide financing for 75% of the project's costs (a
"Project  Loan").  The first 25% of such costs would be contributed as equity by
the Company  prior to or at the same time as the receipt of the debt  financing.
In  connection  with each  project  it  finances,  Tomen has the right to act as
procurement agent for the network project.

         Until amended in May 1996, the Tomen Master Agreement had provided that
Tomen could  purchase up to 10% (on a fully diluted  basis) of the capital stock
of a Development  Company to which it agreed to provide  financing and Tomen had
purchased 10% of the equity of GST Pacific for the sum of $615,000. In May 1996,
the Company entered into a series of transactions  pursuant to which GST Telecom
purchased the shares of GST Pacific held by Tomen for $1,250,000 and the parties
amended the Tomen Master Agreement to eliminate Tomen's right to purchase 10% of
the shares in  Development  Companies to which it provides a Project Loan and to
grant to Tomen in  connection  with each  Project  Loan the right to  purchase a
number of Common Shares the aggregate value of which based on their market price
would  equal  10%  of the  total  equity  contribution  by  the  Company  to the
Development  Company.  In addition,  the parties agreed that in connection  with
certain Project Loans,  Tomen's purchase of Common Shares would include,  for no
additional consideration,  a specified number of warrants to purchase additional
Common Shares.

         The Tomen Master  Agreement  provides  that each Project Loan will bear
interest  at  LIBOR  plus 3% and  will  amortize  in 24  quarterly  installments
beginning  after the project's  construction  period (which may not exceed three
years).  An  upfront  fee of 1.50% of the  aggregate  principal  amount  of each
Project  Loan and a commitment  fee of 0.50% per annum on the unused  portion of
each  Project  Loan is  payable  to  Tomen.  In  addition,  Pacwest,  an  entity
controlled by Mr. Warta,  Chairman of the Board and Chief  Executive  Officer of
the  Company,  is  entitled  to  receive a fee equal to 1% of the total debt and
equity  financing  received by the Company under the Tomen  Facility.  A Project
Loan may be repaid or  refinanced  at any  time;  however,  Tomen has a right of
first  refusal on any such  refinancing  and Tomen  would be entitled to receive
one-third of the net present  value of any  interest  rate savings that would be
realized by the Development Company in connection with any such refinancing.

         Each Project Loan is to be secured by all of the Development  Company's
assets  and a  pledge  of all  capital  stock  of the  Development  Company.  In
addition,  the Tomen Master  Agreement  requires  that the net cash flow of each
project financed under the Tomen Facility be assigned to secure the repayment of
each other Project Loan. Any management fees payable by the Development  Company
are subordinated in right of payment to the repayment of Project Loans.

   
         Pursuant  to a stock  purchase  agreement  (the "Tomen  Stock  Purchase
Agreement")  entered into in connection with the Tomen Master  Agreement,  Tomen
purchased (i) for an aggregate  purchase  price of $2.3 million,  500,000 Common
Shares  and  warrants  to  purchase  250,000  Common  Shares,  which  have  been
exercised,
    

                                      -98-

<PAGE>
   
(ii) for an aggregate of $1.2  million,  250,000  Common  Shares and warrants to
purchase  125,000 Common  Shares,  which have been  exercised,  and (iii) for an
aggregate  of $2.7  million,  250,000  Common  Shares and  warrants  to purchase
125,000  Common Shares  exercisable  until May 23, 1998 at an exercise  price of
$12.96 per share . Pursuant to an amendment to the Tomen  Master  Agreement  and
the Tomen Stock  Purchase  Agreement,  Tomen  purchased  (i) for an aggregate of
$800,000,  74,074 Common Shares and warrants to purchase 46,155 Common Shares at
an exercise  price of $12.96 per share and (ii) for an aggregate of  $1,375,000,
130,828  Common  Shares and  warrants to  purchase  75,000  Common  Shares at an
exercise price of $12.61 per share.  The Company has registered the resale of an
aggregate  of 1,620,229  Common  Shares that have been issued or are issuable to
Tomen upon exercise of warrants.
    

         FINANCED PROJECTS

         The first two projects  financed under the Tomen Master  Agreement were
the San Bernardino  portion of the Southern  California  network ("Phase I") and
the Ontario portion of the Southern California network ("Phase II"). Pursuant to
the  credit  agreement  between  GST  Pacific  and Tomen  America  (the  "Credit
Agreement"),  Tomen agreed to provide $9.0 million of debt  financing to develop
Phase I and $9.5 million of debt financing to develop Phase II. The terms of the
Credit Agreement are  substantially  the terms  contemplated by the Tomen Master
Agreement.  In addition,  the Credit Agreement  contains  covenants which, among
other things,  restrict or prohibit GST Pacific's  ability to incur debt, create
liens, sell assets,  make investments,  enter into transactions with affiliates,
merge or consolidate,  transfer GST Pacific's capital stock and pay dividends to
the Company.  Failure to satisfy any of the  covenants  constitutes  an event of
default under the Credit Agreement. The Credit Agreement also contains customary
events of default for  project  financing,  including  a cross  default to other
indebtedness  of GST  Pacific.  An event of default  under the Credit  Agreement
would allow Tomen to accelerate  the maturity of the Project Loan,  foreclose on
the collateral or take possession of and complete the project.

         In May 1996,  Tomen  provided  financing with respect to the Tucson and
Albuquerque networks, in the amount of up to $8.0 million each. The terms of the
respective credit agreements between Tomen and GST Tucson and GST New Mexico are
substantially similar to the terms of the Credit Agreement.

   
         On September 30, 1997, Tomen provided the Company with $40.5 million of
debt financing for the Company's  Hawaiian  inter-island  submarine  network and
various other  terrestrial  installations.  The fully  operational  inter-island
submarine network is the first to connect six of the major Hawaiian islands. The
terrestrial installations, which are in progress, include a fiber optic backbone
across the island of Hawaii,  a cable  plant on Maui and three fiber optic rings
on Oahu. In connection  with such  financing,  the Company entered into a credit
agreement with Tomen containing  substantially similar terms as those previously
entered into under the Tomen Facility,  except that the loan will amortize in 22
quarterly installments beginning two and one half years after the date financing
was provided.
    

EQUIPMENT FINANCING

         SIEMENS SWITCHING EQUIPMENT PURCHASE AGREEMENT AND LOAN AGREEMENT

         The Company, through its indirect subsidiary,  GST SwitchCo, Inc. ("GST
SwitchCo"),  entered  into the  Siemens  Sales  Agreement  pursuant to which GST
SwitchCo may purchase switching and related equipment from Siemens.  The Siemens
Sales Agreement provides price protection for 10 years for several categories of
Siemens switching equipment and related software. In addition, on the same date,
GST SwitchCo  entered into the Siemens Loan Agreement that provides for up to an
aggregate  of  $226.0  million  of loans to  finance  the  purchase  of  Siemens
equipment  and  equipment  from  other  suppliers,  of which  $116.0  million is
presently available to the Company.  The Company may seek to increase the amount
available up to $226.0 million on an as-needed basis, subject to the negotiation
and execution of mutually satisfactory  documentation.  Each loan made under the
Siemens Loan Agreement initially bears interest at an interim loan rate of LIBOR
plus 4.5% on the  outstanding  balance  of the loan until the  beginning  of the
calendar  quarter  following  the original  loan advance date, at which time the
outstanding

                                      -99-

<PAGE>

balance of the loan  converts to a term loan and begins  accruing  interest at a
term loan rate of LIBOR plus 3.5%. Repayment of the outstanding principal amount
of each loan is required in quarterly installments commencing on the last day of
the fifth  quarter  following  the original loan advance date with the remaining
balance of each  outstanding  loan being  payable in full on the last day of the
24th  quarter   following  such  original  loan  advance  date.  GST  SwitchCo's
obligations under the Siemens Loan Agreement are secured by the grant to Siemens
of a first priority security interest in all products  purchased by GST SwitchCo
with the proceeds of loans by Siemens and are guaranteed in part by GST USA.

         NORTEL SWITCHING EQUIPMENT AND RELATED FINANCING

         The Company,  through its wholly-owned  subsidiary,  GST EquipCo,  Inc.
("GST EquipCo"),  entered into the Nortel Purchase  Agreement  pursuant to which
GST EquipCo may purchase  switching  and related  equipment  and  software  from
Nortel. The Nortel Purchase Agreement provides price protection for 10 years for
several  categories  of Nortel  switching  equipment  and related  products  and
software  and  requires  GST  EquipCo  to  purchase  at least  $50.0  million of
equipment, product and software prior to November 18, 1999.

         The Company has entered into the NTFC Loan  Agreement that provides for
up to $50.0  million to finance the purchase by GST EquipCo of Nortel  equipment
and  products.  Borrowings  under the NTFC Loan  Agreement  may be made  through
December 31, 1998.  Loans under the NTFC Loan  Agreement will bear interest at a
floating  interest rate equal to 90 day LIBOR plus 3.5%. GST EquipCo is required
to pay interest only until  December 31, 1998 under the NTFC Loan  Agreement and
the principal amounts  outstanding  thereunder will become due and payable in 20
consecutive  quarterly  installments  following  such interest only period.  GST
EquipCo's  obligations under the NTFC Loan Agreement are secured by the grant to
NTFC of a first priority security  interest in all Nortel products  purchased by
GST EquipCo with the proceeds of such financing and are guaranteed by GST USA.

SENIOR NOTES AND CONVERTIBLE NOTES

         GST USA issued $312.4  million  principal  amount at maturity of Senior
Notes guaranteed by GST, under a senior notes indenture dated December 19, 1995,
among GST USA, as issuer, GST, as guarantor,  and United States Trust Company of
New York, as trustee,  and GST issued $39.1 million principal amount at maturity
of the  Convertible  Notes  guaranteed  by GST USA,  under a  convertible  notes
indenture dated December 19, 1995, among GST, as issuer,  GST USA, as guarantor,
and United  States Trust  Company of New York,  as trustee.  The 1995 Notes were
issued  in  units,  with  each unit  consisting  of eight  Senior  Notes and one
Convertible  Note.  Cash  interest  does not accrue on the 1995  Notes  prior to
December 15, 2000 at which time the 1995 Notes will have fully accreted to their
principal  amount at maturity.  From and after December 15, 2000, the 1995 Notes
will accrue  interest,  payable  semiannually  in cash, at a rate of 13-7/8% per
annum.

         The Senior Notes and the Senior Notes  guarantee are senior,  unsecured
obligations  of GST USA and GST,  respectively,  ranking  pari passu in right of
payment with all  unsubordinated  obligations of GST USA and GST,  respectively.
The  Convertible   Notes  and  the   Convertible   Notes  guarantee  are  senior
subordinated,  unsecured obligations of GST and GST USA,  respectively,  ranking
junior  in  right  of  payment  to all  senior  obligations  of GST and GST USA,
respectively,  pari passu with all senior  subordinated  indebtedness of GST and
GST USA, respectively.

         The 1995 Notes may be  redeemed  at any time on or after  December  15,
2000,  in whole or in part,  at 106.938% of their  principal  amount at maturity
plus accrued  interest,  declining to 100% of their principal amount at maturity
plus accrued  interest on and after  December 15,  2002.  In addition,  the 1995
Notes are redeemable under certain circumstances in the event of certain changes
affecting Canadian withholding taxes.

         The Convertible  Notes are  convertible,  at the option of the holders,
into Common  Shares at any time after  December 19,  1996.  The number of Common
Shares issuable upon  conversion of Convertible  Notes is determined by dividing
the accreted  value on the date of  conversion  of the  Convertible  Notes being
converted by the conversion

                                      -100-

<PAGE>

price of $7.563, subject to adjustment.  In addition, the Convertible Notes will
automatically convert under certain  circumstances,  if the closing price of the
Common  Shares on the AMEX during any period  described  below exceeds the price
for such period for at least 30 consecutive trading days:

12 MONTHS BEGINNING                                 CLOSING PRICE
- -------------------                                 -------------
December 15, 1996................................     $16 .77
December 15, 1997................................      $19.80
December 15, 1998................................      $22.82
 December 15, 1999...............................      $25.84

         The 1995 Indentures  contain certain  covenants that affect and in some
cases significantly restrict or prohibit, among other things, the ability of GST
and  its  restricted  subsidiaries  (including  GST  USA)  to  incur  additional
indebtedness, create liens, engage in sale-leaseback transactions, pay dividends
or make  distributions  in respect of its capital  stock,  make  investments  or
certain other  restricted  payments,  sell assets,  create  restrictions  on the
ability of restricted subsidiaries to make certain payments, issue or sell stock
of  restricted  subsidiaries,  enter  into  transactions  with  stockholders  or
affiliates  and  consolidate,  merge or sell all or  substantially  all of their
assets.

         Upon the  occurrence of a Change of Control (as  hereinafter  defined),
GST USA will be required to make an offer to purchase  the Senior  Notes and GST
will be required to make an offer to purchase  the  Convertible  Notes,  in each
case at a purchase  price equal to 101% of their  accreted  value on the date of
purchase plus accrued interest, if any. A "Change of Control" is defined to mean
such time as (i) a "person" or "group" (within the meaning of Sections 13(d) and
14(d)(2) of the  Securities  Exchange  Act of 1934,  as amended  (the  "Exchange
Act"),  becomes the ultimate  "beneficial owner" (as defined in Rule 13d-3 under
the Exchange Act) of voting stock representing more than 30% of the total voting
power of the voting stock of GST on a fully diluted basis;  (ii) individuals who
on December 19, 1995  constituted the Board of Directors  (together with any new
directors  whose  election by the Board of  Directors  or whose  nomination  for
election by GST's  shareholders was approved by a vote of at least two-thirds of
the members of the Board of Directors  then in office who either were members of
the Board of Directors on December 19, 1995 or whose  election or nomination for
election was previously  approved) cease for any reason to constitute a majority
of the  members of the Board of  Directors  then in office;  or (iii) all of the
common stock of GST USA is not beneficially owned by GST.

REDEEMABLE PREFERRED SHARES

         In the Princes Gate  Investment,  GST issued 500  Redeemable  Preferred
Shares.  The Redeemable  Preferred Shares will not pay dividends,  except to the
extent that cash dividends are paid on the Common Shares.  The  liquidation  and
redemption  prices  of  the  Redeemable  Preferred  Shares  will  accrete  at  a
semi-annual rate of 117/8%.

         GST is required to redeem the Redeemable  Preferred  Shares on February
28, 2004 (the  "Mandatory  Redemption  Date") in cash at a  redemption  price of
approximately  $224,231 per share (the "Mandatory  Redemption Price");  provided
that to the extent GST is prohibited from paying such redemption  price in cash,
the  holders of  Redeemable  Preferred  Shares  have the option to convert  each
Redeemable Preferred Share into a number of Common Shares equal to the Mandatory
Redemption  Price divided by 95% of the then market price for Common Shares.  In
the event GST is  prevented  from  paying the  redemption  price for  Redeemable
Preferred Shares in cash and any holder of Redeemable  Preferred Shares does not
exercise such conversion  option,  GST has the option of extending the Mandatory
Redemption  Date to  August  28,  2007.  GST has the  option  of  redeeming  the
Redeemable  Preferred  Shares at any time after  February  28, 2000 in cash at a
redemption  price per Redeemable  Preferred  Share equal to the number of Common
Shares into which such Redeemable Preferred Share is then convertible multiplied
by the price at which such  Redeemable  Preferred  Share would become subject to
mandatory  conversion.  Under the terms of the Redeemable  Preferred Shares, the
holders thereof are entitled to designate for election one person to

                                      -101-

<PAGE>

the Board of Directors of GST. In June 1997, Joseph G. Fogg III, designee of the
holders  of the  Redeemable  Preferred  Shares,  was  appointed  to the Board of
Directors of GST.

         Redeemable  Preferred  Shares  are  convertible  at the  option  of the
holders into Common Shares at any time after February 28, 2000 or earlier upon a
change of control of GST. The holders of  Redeemable  Preferred  Shares have the
right to require GST to repurchase  their shares upon a change of control of GST
after  February  28, 2002;  prior to that time,  holders have a right to convert
their  shares  into  Common  Shares  upon a  change  in  control.  Further,  the
Redeemable  Preferred  Shares are subject to  mandatory  conversion  into Common
Shares if the market price of Common Shares  exceeds  $15.925 per share (subject
to adjustment) for a specified period after February 28, 2000.

             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

   
         In the opinion of Olshan  Grundman  Frome & Rosenzweig  LLP, the United
States tax counsel to the Company,  subject to the limitations set forth herein,
the  following is an accurate  summary of the  material  United  States  federal
income tax consequences of the purchase, ownership and disposition of the Notes.
This  summary  is based on current  provisions  of the Code,  applicable  final,
temporary and proposed Treasury Regulations ("Treasury  Regulations"),  judicial
authority,  and current administrative rulings and pronouncements of the Service
and upon the facts concerning the Company as of the date hereof. There can be no
assurance  that the Service will not take a contrary  view,  which  position may
ultimately be upheld by the courts, because the tax effects discussed herein are
not  subject to absolute  prediction  and no ruling from the Service has been or
will be sought by the Company. Legislative,  judicial, or administrative changes
or interpretations  may be forthcoming that could alter or modify the statements
and conclusions set forth herein. Any such changes or interpretations may or may
not be retroactive and could affect the tax consequences to holders.
    

         This  summary and the above  referenced  opinion do not purport to deal
with all aspects of taxation that may be relevant to  particular  holders of the
Notes in light of their personal investment or tax circumstances,  or to certain
types of  investors  (including  insurance  companies,  financial  institutions,
broker-dealers or tax-exempt  organizations)  subject to special treatment under
the United States federal income tax laws.  This  discussion  does not deal with
special tax  situations,  such as the holding of the Notes as part of a straddle
with other  investments,  or  situations in which the  functional  currency of a
holder who is a U.S.  Holder (as defined below) is not the United States dollar.
In addition, this discussion deals only with Notes held as capital assets within
the meaning of Section 1221 of the Code.

         As used in the discussion which follows,  the term "U.S.  Holder" means
an initial  beneficial  owner of the Notes that for United States federal income
tax  purposes  is (i) a  citizen  or  resident  of  the  United  States,  (ii) a
corporation,  partnership  or other entity  created or organized in or under the
laws of the United States or of any political  subdivision  thereof, or (iii) an
estate or trust the income of which is subject to United States  federal  income
taxation  regardless of its source. The term "Non-U.S.  Holder" means an initial
holder of Notes that is, for United States  federal  income tax purposes,  not a
U.S. Holder.

         HOLDERS  SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX
CONSEQUENCES  TO  THEM  OF  PURCHASING,  HOLDING  AND  DISPOSING  OF THE  NOTES,
INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE,  LOCAL OR FOREIGN TAX LAWS.
GENERAL

         Under   applicable   authorities,   the  Notes  should  be  treated  as
indebtedness  for United States  federal  income tax  purposes.  In the unlikely
event the Notes are treated as equity,  the amount of any actual or constructive
distributions  on any such Note would first be taxable to the holder as dividend
income to the  extent of the  issuer's  current  and  accumulated  earnings  and
profits,  and next  would be treated as a return of capital to the extent of the
holder's tax basis in the Note,  with any remaining  amount treated as gain from
the sale of a Note. As a result,  until such time as the issuer has earnings and
profits  as  determined   for  United  States   federal   income  tax  purposes,
distributions  on any Note  treated  as equity  will be a  nontaxable  return of
capital  and will be  applied  against  and in the case of actual  distributions
reduce the  adjusted  tax basis of such Note in the hands of its holder (but not
below  zero).  Further,  payments  on the Notes  treated  as equity to  Non-U.S.
Holders would not be eligible for the portfolio  interest  exception from United
States  withholding tax, and dividends thereon would be subject to United States
withholding tax at a flat rate of 30% (or lower applicable treaty rate) and gain
from their  sale or other  taxable  disposition  might also be subject to United
States tax. In addition,  in the event of equity treatment,  neither GST Funding
nor GST USA, as the case may be,  would ever be  entitled to deduct  interest on
the Notes for United States federal  income tax purposes.  The remainder of this
discussion  assumes that the Notes will  constitute  indebtedness  of either GST
Funding or GST USA, as appropriate, for such tax purposes.

                                      -103-

<PAGE>

TAX CONSEQUENCES TO U.S. HOLDERS

         Subject to the  discussion  below,  stated  interest  payable on to the
Notes will be taxable to a U.S.  Holder as  ordinary  income  when  received  or
accrued in accordance with such holder's regular method of tax accounting.

         The  interest  rate on the Notes will be increased by .5% per annum if,
prior to the date that is six months after the Closing  Date,  GST Funding,  GST
USA and GST fails to either  consummate  the Exchange  Offer or cause resales of
the Notes to be registered  under the Securities  Act. See  "Description  of the
Notes --  Registration  Rights."  According  to the  Treasury  Regulations,  the
possibility  of a change in the  interest  rate will not affect the yield of the
Notes (and,  accordingly,  will not affect the  inclusion of interest in income)
unless,  based on all the facts and  circumstances  as of the issue date,  it is
significantly  more likely than not that such a change will occur.  GST Funding,
GST USA and GST do not  intend  to treat  the  possibility  of a  change  in the
interest rate as affecting the yield to maturity of any Note. If,  however,  the
interest  was  increased  because  of such a  failure,  a U.S.  Holder  would be
required to include in gross income any  increased  amount of interest  over the
remaining term of the Notes, possibly in advance of the receipt of cash relating
thereto.

         MARKET  DISCOUNT.  If a U.S. Holder purchases a Note for an amount that
is less than its stated principal amount,  the amount of such difference will be
treated as "market  discount" for U.S. federal income tax purposes,  unless such
difference is less than a specified de minimis amount. Under the market discount
rules, a U.S. Holder will be required to treat any principal  payment on, or any
gain on the  sale,  exchange,  retirement  or  other  disposition  of, a Note as
ordinary  income to the extent of the market  discount  which has not previously
been  included  in income and is  treated as having  accrued on such Note at the
time of such payment or  disposition.  If a U.S.  Holder makes a gift of a Note,
accrued market  discount,  if any, will be recognized as if such U.S. Holder had
sold such Note for a price equal to its fair market value. In addition, the U.S.
Holder may be required to defer,  until the  maturity of the Note or, in certain
circumstances, the earlier disposition of the Note in a taxable transaction, the
deduction of a portion of the interest expense on any  indebtedness  incurred or
continued to purchase or carry such Note.

         Any market  discount will be  considered  to accrue on a  straight-line
basis during the period from the date of acquisition to the maturity date of the
Note,  unless the U.S.  Holder  elects to accrue  market  discount on a constant
interest method. A U.S. Holder of a Note may elect to include market discount in
income  currently  as it accrues  (on either a  straight-line  basis or constant
interest method), in which case the rules described above regarding the deferral
of interest  deductions will not apply. This election to include market discount
in income  currently,  once  made,  is  irrevocable  and  applies  to all market
discount  obligations  acquired  on or after the first day of the first  taxable
year to which the election applies and may not be revoked without the consent of
the Service.

         AMORTIZABLE  BOND PREMIUM.  A U.S.  Holder that purchases a Note for an
amount  in  excess  of the sum of all  amounts  payable  on the Note  after  the
purchase date other than stated  interest  will be considered to have  purchased
the Note at a  "premium."  A U.S.  Holder may  generally  elect to amortize  the
premium over the  remaining  term of the Note on a constant  yield  method.  The
amount amortized in any year will be treated as a reduction of the U.S. Holder's
interest income from the Note. A U.S. Holder who elects to amortize bond premium
must  reduce its tax basis in the  related  obligation  by the amount of premium
amortized  during  its  holding  period.  Bond  premium on a Note held by a U.S.
Holder that does not make such an election  will  decrease  the gain or increase
the loss  otherwise  recognized  on  disposition  of the Note.  The  election to
amortize  premium  on a  constant  yield  method  once made  applies to all debt
obligations  held or  subsequently  acquired by the electing  U.S.  Holder on or
after the first day of the first taxable year to which the election  applies and
may not be revoked without the consent of the IRS.

         Proposed  regulations  have been issued  that,  if  finalized  in their
current  form,  would  require  that a U.S.  Holder  that  purchases a Note at a
premium, and elects to amortize such premium, must amortize such premium under a
constant  yield  method.  As proposed,  these rules will be  applicable  to debt
instruments  issued on or after 60 days after the  regulations  are published in
final form. However, a U.S. Holder may elect to apply the new rules

                                      -104-

<PAGE>

to all Notes held on or after the first day of the  taxable  year that  contains
the day which is 60 days after the regulations are published in final form.

         SALE OR OTHER  DISPOSITION.  In  general,  a U.S.  Holder of Notes will
recognize  gain or loss upon the sale,  exchange,  redemption,  or other taxable
disposition of such Notes  measured by the difference  between (i) the amount of
cash and the fair  market  value of  property  received  (except  to the  extent
attributable to accrued interest on the Notes previously taken into account) and
(ii) the U.S.  Holder's tax basis in the Notes,  and market discount  previously
included in income by the U.S. Holder and decreased by amortizable bond premium,
if any,  deducted  over the term of the Notes.  Subject  to the market  discount
rules discussed above, any such gain or loss will generally be long-term capital
gain or loss,  provided  the Notes  have  been held for more than one year.  The
excess of net long-term  capital  gains over net  short-term  capital  losses is
taxed at a lower rate than ordinary income for certain non-corporate  taxpayers.
The distinction between capital gain or loss and ordinary income or loss is also
relevant for purposes of, among other things,  limitations on the  deductibility
of capital losses.

         In general,  an exchange of outstanding bonds such as the Old Notes for
newly  issued  bonds such as the New Notes is treated as tax free to  exchanging
creditors and the debtor.  In this case, a U.S.  Holder's basis in the New Notes
is  generally  the same as his  basis  in the Old  Notes  and the U.S.  Holder's
holding  period in the New Notes includes the period for which the Old Notes had
been held.  Although no gain or loss would be recognized  to an exchanging  U.S.
Holder under these  circumstances,  if the exchange of the Old Notes for the New
Notes were deemed to constitute an exchange of a debt  instrument for a modified
debt  instrument  that differed  materially in kind or in extent,  and the issue
price of the New Notes (which would be their  publicly-traded  fair market value
on the date on which a  substantial  amount of the New Notes is issued) was less
than  that of the Old  Notes,  original  issue  discount  could  arise to a U.S.
Holder.

   
         However,  for purposes of the original issue discount provisions of the
Code, the exchange of the New Notes for the Old Notes is likely to be considered
a retention by the U.S. Holder of the Old Notes in modified form. Under Treasury
Regulations,  a  "significant  modification"  of a debt  instrument is deemed to
result in an exchange of the original instrument for a modified instrument, and,
conversely, a modification that is not a "significant  modification" is not such
an exchange.  The term  "modification" is defined as any alteration in any legal
right  or  obligation  of the  issuer  or  holder  of a debt  instrument,  and a
modification  is  "significant"  if it  either  falls  within  any  one  of  the
categories  set  forth  in  the  Treasury  Regulations  or is  determined  to be
significant based on the facts and circumstances. Nevertheless, any modification
of a debt  instrument  that arises as a result of the  original  terms of a debt
instrument,  where the modified  instrument  continues to represent debt (rather
that equity),  is not treated as giving rise to a "modification" of the debt and
hence does not give rise to an exchange.  Inasmuch as the original  terms of the
Old Notes contemplated their  registration,  in the view of counsel,  it appears
likely, based on the provisions of the Treasury  Regulations,  that the exchange
by a U.S.  Holder  of the New Notes  for the Old  Notes  should  not be deemed a
modification  and  therefore  not  constitute  an  exchange  of the  Old  Notes.
Moreover,  any future  assumption of the New Notes by GST USA should also not be
deemed a taxable  exchange of the New Notes at that time under an exception  set
forth in the Treasury  Regulations , providing that no significant  modification
occurs where the  substitution  of an obligor takes places in connection  with a
qualifying  reorganization,  the  transaction  does not  result  in a change  in
payment  expectations  and the  transaction  does not  result  in a  significant
alteration of legal rights or obligations under the instrument.
    

TAX CONSEQUENCES TO NON-U.S. HOLDERS

         A  Non-U.S.  Holder  will  generally,   under  the  portfolio  interest
exemption  of the Code,  not be subject to United  States  federal  income taxes
and/or United States  withholding  tax, on interest paid on the Notes,  provided
that (i) the Non-U.S. Holder does not actually or constructively own 10% or more
of the total combined voting power of all classes of stock of either GST Funding
or GST  USA  entitled  to  vote,  (ii)  the  Non-U.S.  Holder  is not (a) a bank
receiving  interest  pursuant to a loan  agreement  entered into in the ordinary
course of its trade or business or (b) a controlled foreign  corporation that is
related to either GST Funding or GST USA (actually or

                                      -105-
<PAGE>

constructively) through stock ownership,  (iii) such interest is not effectively
connected  with a United  States  trade or  business  and  (iv)  either  (a) the
beneficial  owner of the Notes  certifies to the Issuer (GST Funding or GST USA,
as the case may be) or its agent,  under penalties of perjury,  that it is not a
U.S.  Holder and  provides a  completed  IRS Form W-8  ("Certificate  of Foreign
Status") or (b) a  securities  clearing  organization,  bank or other  financial
institution  which holds  customers'  securities  in the ordinary  course of its
trade or business (a "financial  institution") and holds the Notes, certifies to
the Issuer or its agent,  under penalties of perjury,  that it has received Form
W-8 from the  beneficial  owner or that it has received  from another  financial
institution  a Form  W-8  and  furnishes  the  payor  with a copy  thereof.  The
certification may be made on an IRS Form W-8 or substantially similar substitute
form,  and a  non-U.S.  Holder  must  inform GST  Funding,  GST USA or any agent
thereof of any change in the information or the statement  within 30 days of the
change.  A non-U.S.  Holder of a Note who does not meet the  requirements of the
second  preceding   sentence,   would  generally  be  subject  to  U.S.  federal
withholding  at a flat  rate of 30%  (or a  lower  applicable  treaty  rate)  on
payments of interest on the Notes. The Service has proposed  regulations that if
finalized  would  modify  certain of the  certification  requirements  described
above.

         If a Non-U.S. Holder of a Note is engaged in a trade or business in the
United States and interest on the Note is effectively connected with the conduct
of such  trade or  business,  or, if a tax  treaty  applies,  such  interest  is
attributable to a U.S. permanent  establishment  maintained by such holder, such
Non-U.S. Holder, although exempt from U.S. federal withholding tax (by reason of
the  delivery  of a  properly  completed  IRS Form 4224) will be subject to U.S.
federal  income tax on such  interest in  essentially  the same manner as a U.S.
Holder. In addition,  if such Non-U.S.  Holder is a foreign corporation,  it may
also be  subject  to a U.S.  foreign  branch  profits  tax  equal  to 30% of its
effectively  connected  earnings and profits  (subject to  adjustment)  for that
taxable year,  unless it qualifies  for a lower rate under an applicable  income
tax treaty.

         In the unlikely  event the Notes were  treated as equity,  the periodic
distributions  received by a Non-U.S.  Holder on the Notes would not qualify for
the portfolio interest exemption from United States federal income tax described
above.  Rather,  the  periodic  distributions  would be  subject to a 30% United
States  withholding tax in the case where income on the Note was not effectively
connected with a U.S. trade or business of such Non-U.S.  Holder. Under Treasury
Regulations,  the  withholding  agent will be required to withhold  tax from all
distributions  paid  on the  stock  regardless  of the  company's  earnings  and
profits,  but  holders  may  apply  for  refunds  if such  stock's  share of the
company's earnings and profits is less than the amount of the distributions. The
rate of  withholding  may be  reduced  to the  extent  provided  by a tax treaty
between the United States and the country of which the Non-U.S.  Holder is a tax
resident.

         Subject  to the  discussion  of backup  withholding  below,  a Non-U.S.
Holder will  generally not be subject to United States federal income tax on any
gain  realized in  connection  with the sale,  exchange or  redemption of Notes,
unless (i) the gain is effectively connected with a trade or business carried on
by the Non-U.S.  Holder within the United States (by reason of the delivery of a
properly completed IRS Form 4224) or, if a treaty applies, the gain is generally
attributable  to the United  States  permanent  establishment  maintained by the
Non-U.S.  Holder, or (ii) the Non-U.S. Holder is an individual who is present in
the United  States for 183 days or more in the taxable year of  disposition  and
certain other conditions are satisfied.

         Notes held by an individual  who is neither a citizen nor a resident of
the United  States for U.S.  federal  income  tax  purposes  at the time of such
individual's death will not be subject to U.S. federal estate tax, provided that
the income from the Notes was not or would not have been  effectively  connected
with a U.S.  trade or  business  of such  individual  and that  such  individual
qualified for the exemption from U.S. federal withholding tax (without regard to
the certification requirements) that is described above.

         Non-U.S.  Holders should consult with their tax advisers regarding U.S.
and foreign tax consequences with respect to the Notes.

EARNING STRIPPING RULES

         Under  Section  163(j)  of  the  Code,  no  deduction  is  allowed  for
"disqualified  interest" paid or accrued by a corporation  during a taxable year
if (i) such  corporation has "excess  interest  expense" (as defined by the Code
generally to mean the excess,  if any, of the corporation's net interest expense
over 50% of the "adjusted  taxable income" of the  corporation)  for the taxable
year, and (ii) the ratio of debt to equity of such corporation exceeds 1.5 to 1.
"Disqualified  interest"  includes any interest paid or accrued by a corporation
with respect to debt that is guaranteed  by a foreign  person that is related to
such  corporation to the extent that no gross basis United States tax is imposed
with respect to such  interest.  GST Funding  expects that Section 163(j) of the
Code may  apply to limit the  deductibility  of  interest  by GST  Funding  with
respect to the Notes.

BACKUP WITHHOLDING AND INFORMATION REPORTING

         "Backup" withholding and information  reporting  requirements may apply
to certain  payments of principal and interest on a Note and to certain payments
of proceeds of the sale or retirement of a Note. GST Funding,  GST USA, GST, any
agent thereof,  a broker,  the Trustee or any paying agent,  as the case may be,
will be  required to  withhold  tax from any  payment  that is subject to backup
withholding at a rate of 31% of such payment if the U.S. Holder fails to furnish
his  taxpayer   identification   number  (social  security  number  or  employer
identification  number),  to  certify  that such U.S.  Holder is not  subject to
backup withholding,  or to otherwise comply with the applicable  requirements of
the backup withholding rules. Certain U.S. Holders (including, among others, all
corporations)   are  not  subject  to  the  backup   withholding  and  reporting
requirements.

         Under current Treasury Regulations,  backup withholding and information
reporting will not apply to payments made by GST Funding,  GST USA or GST or any
agent  thereof (in its  capacity as such) to a Holder of a Note who has provided
the  required  certification  under  penalties  of perjury that it is not a U.S.
Holder  as  set  forth  in  clause  (iv)  in  the  first  paragraph  under  "Tax
Consequences  to Non-U.S.  Holders" or has  otherwise  established  an exemption
(provided that neither the company nor such agent has actual  knowledge that the
Holder is a U.S. Holder or that the conditions of any other exemption are not in
fact satisfied).

         Payment of the  proceeds  from the sale by a non-U.S.  Holder of a Note
made to or  through a foreign  office of a broker  will not be  subject  to U.S.
information reporting or backup withholding, except that if the broker is a U.S.
person, a controlled foreign corporation for U.S. federal income tax purposes or
a foreign person 50% or more of whose gross income is effectively connected with
a United  States  trade or business  for a  specified  three-year  period,  U.S.
information reporting,  but not backup withholding,  may apply to such payments.
Payments of the proceeds from the sale of a Note to or through the United States
office  of a  broker  is  subject  to  U.S.  information  reporting  and  backup
withholding  unless the Holder certifies as to its non-U.S.  status or otherwise
establishes an exemption from U.S. information reporting and backup withholding.

         Any amounts withheld under the backup  withholding rules from a payment
to a Holder may be claimed as a credit against such Holder's U.S. federal income
tax  liability,  provided  that the  required  information  is  provided  to the
Service.

         THE  FOREGOING  SUMMARY  DOES NOT DISCUSS ALL ASPECTS OF UNITED  STATES
FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO A PARTICULAR  HOLDER OF NOTES IN
LIGHT OF ITS PARTICULAR  CIRCUMSTANCES AND INCOME TAX SITUATION.  HOLDERS SHOULD
CONSULT THEIR OWN TAX ADVISOR AS TO THE SPECIFIC TAX  CONSEQUENCES  TO THEM FROM
THE PURCHASE,  OWNERSHIP AND DISPOSITION OF NOTES, INCLUDING THE APPLICATION AND
EFFECT OF STATE,  LOCAL,  FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF
CHANGES IN UNITED STATES OR OTHER TAX LAWS.

                              PLAN OF DISTRIBUTION

         Except as described below,  (i) a broker-dealer  may not participate in
the Exchange Offer in connection with a distribution of the New Notes, (ii) such
broker-dealer   would  be  deemed  an  underwriter   in  connection   with  such
distribution and (iii) such  broker-dealer  would be required to comply with the
registration  and  prospectus  delivery  requirements  of the  Securities Act in
connection with any secondary resale transactions. A broker-dealer may, however,
receive New Notes for its own account pursuant to the Exchange Offer in exchange
for Old Notes when such Old Notes  were  acquired  as a result of  market-making
activities or other trading activities. Each such broker-dealer must acknowledge
that it will  deliver a  prospectus  in  connection  with any resale of such New
Notes. This Prospectus,  as it may be amended or supplemented from time to time,
may be used by a  broker-dealer  (other than an  "affiliate"  of the Company) in
connection  with  resales of such New Notes.  GST  Funding has agreed that for a
period of 180 days after the Expiration Date, it will make this  Prospectus,  as
amended  or  supplemented,  available  to  any  such  broker-dealer  for  use in
connection with any such resale.

         GST Funding will not receive any proceeds from any sale of New Notes by
broker-dealers.  New Notes  received  by  broker-dealers  for their own  account
pursuant  to the  Exchange  Offer  may be sold  from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the  writing  of options on the New Notes or a  combination  of such  methods of
resale,  at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated  prices. Any such resale may be made
directly  to  purchasers  or to or through  brokers or dealers  who may  receive
compensation   in  the  form  of  commissions  or  concessions   from  any  such
broker-dealer  and/or the  purchasers of any such New Notes.  Any  broker-dealer
that resells New Notes that were received by it for its own account  pursuant to
the Exchange  Offer may be deemed to be an  "underwriter"  within the meaning of
the  Securities  Act and any  profit  on any such  resale  of New  Notes and any
commissions  or  concessions  received  by any such  persons may be deemed to be
underwriting  compensation  under the Securities  Act. The Letter of Transmittal
states  that  by  acknowledging  that  it  will  deliver  and  by  delivering  a
prospectus,  a  broker-dealer  will  not  be  deemed  to  admit  that  it  is an
"underwriter" within the meaning of the Securities Act.

         For a period of 180 days after the  Expiration  Date,  GST Funding will
promptly  send  additional  copies  of  this  Prospectus  and any  amendment  or
supplement to this Prospectus to any broker-dealer  that requests such documents
in a Letter of Transmittal.  GST Funding has agreed to pay all expenses incident
to the Exchange  Offer other than  commissions  or concessions of any brokers or
dealers  and  transfer  taxes and will  indemnify  the  Holders of the Old Notes
(including  any   broker-dealers)   against   certain   liabilities,   including
liabilities under the Securities Act.

         The Placement  Agents have indicated to GST Funding that they intend to
effect  offers  and  sales of the New  Notes in  market-making  transactions  at
negotiated  prices related to prevailing  market prices at the time of sale, but
is not obligated to do so and such market-making  activities may be discontinued
at any  time.  The  Placement  Agents  may act as  principal  or  agent  in such
transactions.  There can be no assurance that an active market for the New Notes
will develop.


                                  LEGAL MATTERS

         Certain  legal  matters in  connection  with the Notes are being passed

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders
GST Equipment Funding, Inc.:

We have audited the accompanying  balance sheet of GST Equipment  Funding,  Inc.
(the  Company) as of June 30, 1997,  and the related  statement  of  operations,
shareholder's  deficit,  and cash flows for the period of March 5, 1997 (date of
inception) to June 30, 1997. These financial  statements are the  responsibility
of the  Company's  management.  Our  responsibility  is to express an opinion on
these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards  require that we plan and perform the audit to obtain reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of GST Equipment Funding, Inc. as
of June 30,  1997,  and the  results  of its  operations  and cash flows for the
period of March 5, 1997 (date of inception) to June 30, 1997 in conformity  with
generally accepted accounting principles.

                                  JUNE 30, 1997

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       DESCRIPTION OF THE COMPANY

       GST  Equipment  Funding,  Inc. (the Company) was formed on March 5, 1997.
       The  Company  is  a  wholly-owned  subsidiary  of  GST  USA,  which  is a
       wholly-owned subsidiary of GST Telecommunications, Inc.

       The Company's  operations are limited to (i) purchasing  equipment,  (ii)
       selling equipment to parent,  (iii) receiving payments under Intercompany
       Notes,  and (iv)  making  payments of interest  and  principal  on senior
       secured notes.

       RESTRICTED CASH AND INVESTMENTS

       Pursuant to the terms of the senior secured notes issued on May 13, 1997,
       the Company's use of the net proceeds are restricted for the  acquisition
       of equipment and payment of interest.

       INVESTMENTS

       The Company  classifies its investments,  consisting  exclusively of U.S.
       Treasury  securities,   as   available-for-sale   and   held-to-maturity.
       Held-to-maturity  investments,  totaling $94,547 and maturing between one
       and three years, are restricted for interest payments. Available-for-sale
       investments,  totaling  $110,214 and  maturing  between one month and two
       years,   are   restricted   for  equipment   purchases.   Amortized  cost
       approximates the market value of investment securities at June 30, 1997.


       DEFERRED FINANCING COSTS

       Deferred financing costs consisting of legal, accounting and underwriting
       fees related to the May 13, 1997 debt offering have been deferred and are
       being amortized to interest expense over the life of the Note.

                                                                     (Continued)

                                 (IN THOUSANDS)

       INCOME TAXES

       The  Company  accounts  for income  taxes  under the asset and  liability
       method.  Under the asset and  liability  method,  deferred  income  taxes
       reflect the future tax consequences of differences  between the tax bases
       of assets and liabilities and their financial  reporting  amounts at each
       year-end.  Deferred tax assets and liabilities are measured using enacted
       tax rates expected to apply to taxable income in the years in which those
       temporary differences are expected to be recovered or settled. The effect
       on deferred  tax assets and  liabilities  of a change in the tax rates is
       recognized  in income in the period that  includes  the  enactment  date.
       Valuation  allowances are  established  when necessary to reduce deferred
       tax assets to the amounts expected to be realized.

       FINANCIAL INSTRUMENTS

       The  carrying  amounts  reported in the  balance  sheet for cash and cash
       equivalents,   short-term   borrowings,   accounts  payable  and  accrued
       liabilities  approximate  fair values due to the short  maturity of those
       instruments.

       The carrying amount of the Company's long-term debt approximates its fair
       value.  The fair value of the  Company's  long-term  debt was  determined
       based on quoted  market  prices for  similar  issues or on current  rates
       available to the Company for debt of the same  remaining  maturities  and
       similar terms.

       Fair  value  estimates  are made at a  specific  point in time,  based on
       relevant  market  information  about  the  financial  instrument.   These
       estimates are subjective in nature and involve  uncertainties and matters
       of  significant   judgment  and  therefore   cannot  be  determined  with
       precision.   Changes  in  assumptions  could  significantly   affect  the
       estimates.

       USE OF ESTIMATES

       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.

                                                                     (Continued)

(2) FINANCING ARRANGEMENTS

       LONG-TERM DEBT

       The Company's long-term debt consists of the following at June 30, 1997:

           Senior secured notes, interest at 13.25%
               with semi-annual interest payments due
               commencing November 1, 1997,
               principal due May 13, 2007 .....................   $     265,000
                                                                        =======

       ISSUANCE OF SENIOR SECURED NOTES

       The Company  completed a private  placement  (the May Offering)  under an
       indenture  (the  Indenture)  dated May 13,  1997,  of  $265,000 of senior
       secured notes (the Notes).  The Notes bear interest at 13.25%  payable in
       semi-annual  installments  commencing November 1, 1997. Net proceeds from
       the May Offering totaled  approximately  $255,800,  and are to be used to
       refinance  approximately $41,500 of intercompany  indebtedness,  and fund
       the purchase of equipment and the first six scheduled  interest  payments
       on the Notes. Pursuant to the Indenture,  all purchased equipment will be
       sold to GST USA for use in its  telecommunications  operations  (see note
       3). The Notes are secured by a first  priority  security  interest in the
       equipment and the restricted  investment  securities held for the payment
       of interest. The Notes are subject to certain debt covenants.

       The  Indenture  provides  the GST USA  will  assume  and  become a direct
       obligor on the Notes and GST will guarantee the Notes on May 13, 2000, or
       earlier if permitted by the terms of their  existing  debt.  Once assumed
       the  Notes  will be  secured  senior  indebtedness  of GST USA.  The Note
       Guarantee will be senior unsecured indebtedness of GST. 

       The Notes are  redeemable  at the option of GST USA, in whole or in part,
       at any time,  on or after May 1, 2002,  initially  at  106.625%  of their
       principal amount, plus accrued and unpaid interest,  declining ratably to
       100% on or after May 1, 2004.  If on May 13, 2000,  GST USA is prohibited
       from  assuming  all of the Notes,  the Company will redeem the portion of
       the Notes that cannot be assumed at 101% of their  principal  amount plus
       accrued interest at the date of redemption.

                                                                     (Continued)

(3) RELATED PARTY TRANSACTIONS

       The Company acts as a  purchasing  agent for GST USA and sells to GST USA
       the equipment it purchases  with the proceeds  from the May Offering.  At
       June 30, 1997,  the  Company's  cumulative  purchases for GST USA totaled
       $54,264,  represented  by the  note  receivable  from  parent.  The  note
       receivable bears interest at 15.25%,  compounded  semiannually on May and
       November 1, and is payable in full on May 13, 2000.

(4) INCOME TAXES

       Income tax expense for the period from March 5, 1997 (date of  inception)
       to June 30, 1997, consists of:

                                      CURRENT       DEFERRED       TOTAL
                                      -------       --------       -----

         Federal                   $     1,004            -         1,004
         State                             -              -           -
                                      --------     ---------      -------

                                   $     1,004            -         1,004
                                      ========     =========      =======

       The actual  expense  differs  from the  "expected"  expense  computed  by
       applying the U.S. federal corporate rate as follows:

         Computed "expected" income tax expense             $      (628)

         Increase resulting from:
             Change in valuation allowance                        1,632
                                                                --------

         Actual tax expense                                 $     1,004
                                                                =======

       The tax effects of temporary  differences  that give rise to deferred tax
       assets  and  deferred  tax  liabilities  at June 30,  1997,  are  derived
       primarily  from  interest  expense  not  currently   deductible  for  tax
       purposes.  Gross deferred tax assets and liabilities amount to $1,632 and
       $-0-, respectively, at June 30, 1997.


       The valuation  allowance for deferred tax assets as of June 30, 1997, was
       $1,632.  The net change in the total  valuation  allowance for the period

To the Board of Directors of 
GST USA, Inc.

We have audited the consolidated statements of operaitons,  shareholders' equity
and cash flows of GST USA,  Inc. for the thirteen  months  ended  September  30,
1994.  These  financial  statements  are  the  responsibility  of the  Company's
mangement.  Our  responsibility  is to express  an  opinion  on these  financial
statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards  require that we plan and perform an audit to obtain
reasonable  assurance  whether  the  financial  statements  are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management, as well as evaluating the overall financial statement presentation.

In our opinion,  these consolidated  financial statements present fairly, in all
material  respects,  the  results of its  operations  and its cash flows for the
thirteen  months ended  September 30, 1994, and its  shareholders'  equity as at
September 30, 1994, in accordance with generally accepted accounting  principles
in the United States.

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   (a) DESCRIPTION OF THE COMPANY

       GST  USA,  Inc.  (the  Company)  is  a  wholly-owned  subsidiary  of  GST
       Telecommunications, Inc. (GST), a Canadian company, and is engaged in the
       business of providing  competitive local exchange  services  primarily in
       the western United States.  In addition,  the Company provides a range of
       telecommunications  services which include long distance, Internet access
       and data  services.  The  Company  also  manufactures  telecommunications
       switching  equipment.  The Company was formed in August of 1994,  and GST
       transferred all of its operating  subsidiaries and equity  investments to
       the Company.

   (b) BASIS OF CONSOLIDATION

       The accompanying  consolidated  financial statements include the accounts
       of the Company and its greater than 50% owned subsidiaries. The Company's
       investments in  unconsolidated  companies owned 20% or more are accounted
       for using the equity method. The consolidated  financial statements as of
       and for the thirteen  months ended September 30, 1994 reflect the results
       of operations, financial position and cash flows of each of the operating
       subsidiaries  using the "as if" pooling of interest  basis of accounting,
       as the entities were under common control during the period.  The assets,
       liabilities and equity of each subsidiary and equity investment have been
       combined  retroactively  on an account by account basis at GST's carrying
       values.

   (c) CASH AND CASH EQUIVALENTS

       Cash equivalents  consist of short-term,  highly liquid  investments with
original maturities of ninety days or less.

   (d) RESTRICTED CASH

       Pursuant to an agreement  between the Company and a vendor  relating to a
       construction  in  progress  as of  September  30,  1996,  the  Company is
       required to  maintain  $16 million in a  restricted  account  pending the
       completion of the project as collateral  against  payment.  Completion of
       the project is  anticipated  in the next fiscal year.  At  September  30,
       1996,  the Company is committed to purchase  approximately  $20.7 million
       relating to this project.


                                                                     (Continued)

                      (In thousands, except share amounts)




   (e) ACCOUNTS AND NOTES RECEIVABLE

       The  Company  maintains  a security  interest  in the  telecommunications
       systems it sells until the Company is paid in full.  Management  provides
       an allowance  for doubtful  accounts and notes based on current  customer
       information  and  historical  statistics.   The  allowance  for  doubtful
       accounts  was  $1,183  and  $1,401  at  September   30,  1996  and  1995,
       respectively.

    (f) INVESTMENTS

       The Company  adopted the provisions of Statement of Financial  Accounting
       Standards No. 115,  Accounting for Certain Investments in Debt and Equity
       Securities  (Statement 115) at October 1, 1994.  Under Statement 115, the
       Company  classifies  its  debt  and  equity  securities  in one of  three
       categories:  trading,  available-for-sale,  or held-to-maturity.  Trading
       securities  are bought and held  principally  for the  purpose of selling
       them in the near term.  Held-to-maturity  securities are those securities
       in which the  Company  has the  ability  and intent to hold the  security
       until  maturity.   All  other  securities  not  included  in  trading  or
       held-to-maturity are classified as available-for-sale.

       Trading and available-for-sale securities are recorded at fair value. All
       of  the  Company's  investments  comprised  primarily  of  U.S.  Treasury
       Securities and commercial paper, are classified as available-for-sale and
       mature in periods ranging from three to nine months.  Unrealized  holding
       gains and losses,  net of the related tax effect,  on  available-for-sale
       securities  are  excluded  from  earnings  and are reported as a separate
       component of shareholders' equity until realized. A decline in the market
       value of any available-for-sale  security below cost that is deemed other
       than temporary is charged to earnings  resulting in the  establishment of
       new cost  basis for the  security.  Dividend  income is  recognized  when
       earned.   Realized  gains  and  losses  for   securities   classified  as
       available-for-sale  are  included in earnings  and are derived  using the
       specific-identification  method for  determining  the cost of  securities
       sold.  The  amortized  cost   approximated  the  market  value  of  these
       securities at September 30, 1996 and 1995.


                                                                     (Continued)

   (g) INVENTORY

       Inventory is stated at the lower of cost (first-in,  first-out) or market
       (net realizable value) and consists of the following at September 30:

                                                    1996          1995

                                                  ========        ====

   (h) INVESTMENTS IN AFFILIATES

       The  Company  has a  50%  interest  in  Phoenix  Fiber  Access,  Inc.,  a
       competitive access fiber optic telecommunications network in the Phoenix,
       Arizona  metropolitan area. The carrying value of this investment,  which
       is  included in other  assets in the  accompanying  consolidated  balance
       sheet was $1,364 and $2,859 at September 30, 1996 and 1995, respectively.

    (i) PROPERTY AND EQUIPMENT

       Property  and  equipment  is recorded at cost and is  depreciated  on the
       straight-line  basis  over their  estimated  useful  lives,  which are as
       follows:

           Telecommunications networks                          10 years
           Electronic and related equipment                     10 years
           Leasehold improvements                               10 years
           Furniture, office equipment and other            3 - 7 years
           Building                                             40 years

       Construction,  engineering  and overhead  costs  directly  related to the
       development of competitive  access networks are capitalized.  The Company
       begins  depreciating  these costs when the networks  become  commercially
       operational. Depreciation is provided using the straight-line method over
       the estimated useful lives of the assets owned.


                                                                     (Continued)

                      (In thousands, except share amounts)


    (j) GOODWILL

       Goodwill, which represents the excess of the purchase price over the fair
       value of net assets acquired, is amortized over periods ranging from five
       to twenty years using the straight-line  method. The Company assesses the
       recoverability  of this  intangible  asset  by  determining  whether  the
       amortization  of the  goodwill  balance  over its  remaining  life can be
       recovered through discounted  projected future cash flows of the acquired
       businesses  from  which  the  goodwill  arose.  Amortization  charged  to
       operations was $1,528,  $389 and $19 for the periods ended  September 30,
       1996, 1995 and 1994, respectively.

   (k) REVENUE RECOGNITION

       Telecommunication  services  revenue is recorded upon placing of calls or
       rendering of other related services. Telecommunication product revenue is
       recorded  upon  shipment of product and is presented in the  accompanying
       consolidated statements of operations net of product returns.

       Deferred  revenue,  of which $477 and $373 are included in other  current
       liabilities in the  accompanying  balance sheet at September 30, 1996 and
       1995,  respectively,   consists  of  monthly  service  contract  payments
       received in advance,  warranty  payments received in advance and research
       and development  advances.  Advance warranty  payments are amortized over
       the length of warranty on the system sold, which is typically one year.

   (l)  LOSS PER SHARE

       The Company  does not have any equity  instruments  which are  considered
       common stock  equivalents,  and as weighted  average  common shares total
       only 10 for all periods, loss per share information is not meaningful and
       is not presented in the accompanying consolidated financial statements.


   (m) ISSUANCE OF SUBSIDIARY STOCK

       Issuances of subsidiary  stock are accounted for as capital  transactions
       in the accompanying consolidated financial statements.

   (n) SEGMENTED INFORMATION

       Segmented  information has not been presented as the Company is presently
       operating 100% in the telecommunications industry.


                                                                     (Continued)

                      (In thousands, except share amounts)



   (o) INCOME TAXES

       The  Company  accounts  for income  taxes  under the asset and  liability
       method.  Under the asset and  liability  method,  deferred  income  taxes
       reflect the future tax consequences of differences  between the tax bases
       of assets and liabilities and their financial  reporting  amounts at each
       year-end.  Deferred tax assets and liabilities are measured using enacted
       tax rates expected to apply to taxable income in the years in which those
       temporary differences are expected to be recovered or settled. The effect
       on deferred  tax assets and  liabilities  of a change in the tax rates is
       recognized  in income in the period that  includes  the  enactment  date.
       Valuation  allowances are  established  when necessary to reduce deferred
       tax assets to the amounts expected to be realized.


   (p) FINANCIAL INSTRUMENTS

       The  carrying  amounts  reported in the  balance  sheet for cash and cash
       equivalents,  receivables,  short-term investments, short-term borrowings
       and accounts payable and accrued liabilities  approximate fair values due
       to the short maturity of those instruments.

       The carrying amount of the Company's long-term debt approximates its fair
       value.  The fair value of the  Company's  long-term  debt was  determined
       based on quoted  market  prices for  similar  issues or on current  rates
       available to the Company for debt of the same  remaining  maturities  and
       similar terms.

       Fair  value  estimates  are made at a  specific  point in time,  based on
       relevant  market  information  about  the  financial  instrument.   These
       estimates are subjective in nature and involve  uncertainties and matters
       of  significant   judgment  and  therefore   cannot  be  determined  with
       precision.   Changes  in  assumptions  could  significantly   affect  the
       estimates.



                                                                     (Continued)

   (q) USE OF ESTIMATES

       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.

(2) ACQUISITIONS

     Since  inception,  the Company has made the  acquisitions  set forth below,
     each of which was accounted for as a purchase.  The consolidated  financial
     statements  include  the  operating  results  from  the  effective  date of
     acquisition.

   (a) GST TELECOM, INC. (GST TELECOM)

       In the third  quarter  of 1994,  GST  acquired  60% of the  shares of GST
       Telecom  in  exchange  for  contributing  60% of  the  shares  of  Tucson
       Lightwave,  Inc. (Tucson) and a commitment to provide at least $11,024 in
       equity  financing.  GST  Telecom  develops,   constructs,   and  operates
       competitive local exchange networks and other communications systems. The
       shares of Tucson were  acquired  from  Pacwest,  LLC (Pacwest) (an entity
       controlled by the Chief Executive Officer of the Company) in exchange for
       100,000  common  shares  of GST  valued  at  $447.  GST  transferred  its
       investment to the Company in the fourth  quarter of 1994. The Company and
       GST have made  $132,184 in equity  contributions  to GST Telecom  through
       September 30, 1996.

       In the third quarter of 1995,  the Company  acquired an additional 20% of
       GST Telecom for 1,000,000 common shares of GST valued at $5 per share.

       In the first quarter of 1996,  the Company  acquired the remaining 20% of
       GST  Telecom for  consideration  of up to a maximum of  1,000,000  common
       shares of GST  (valued at $10.00 per  share)  based upon the fair  market
       value of a 20%  interest  in GST  Telecom,  which  was  determined  by an
       independent  appraisal  during September 1996.  Currently,  the 1,000,000
       common  shares  of GST are held in escrow  pending  the  release  of such
       shares.  In addition,  the parties  agreed that the Company has fulfilled
       all of its  obligations  relating  to the  funding of GST Telecom and its
       subsidiaries.

       In connection with these  acquisitions,  the Company  recorded $40,516 in
       assets, including goodwill of $15,330, and liabilities of $3,478.


                                                                     (Continued)

   (b) NATIONAL APPLIED COMPUTERS TECHNOLOGIES, INC. (NACT)

       During 1993 and 1994,  GST  purchased  80% of the common  shares of NACT.
       GST's  investment  in NACT  was  transferred  to the  Company  in the 4th
       quarter of 1994.  Subsequent to September 30, 1994. The Company  acquired
       the  remaining  20%  interest  of NACT.  NACT is a Utah  manufacturer  of
       telecommunications  switching  and network  management  equipment for the
       inter-exchange industry.

       The  consideration  paid for 100% of  NACT's  outstanding  common  shares

   (d) TOMEN AMERICA, INC. FACILITY

       In the first quarter of 1995, the Company entered into a master financing
       agreement with Tomen America,  Inc. (Tomen).  Under the agreement,  Tomen
       will  loan  up to  $100  million  to  subsidiaries  of  the  Company  for
       development  and  construction  of network  projects.  An up front fee of
       1.50%  of the  aggregate  principal  amount  of each  project  loan and a
       commitment  fee of 0.50% per annum on the unused  portion of each project
       loan is  payable to Tomen.  Tomen  will  evaluate  each  network  project
       separately to determine if it will  participate in financing the project.
       The  agreement  originally  provided  Tomen the right to  purchase  a 10%
       equity  interest in each network  project it  financed.  Pursuant to such
       right, in 1995 Tomen  purchased a 10% interest in the Company's  southern
       California project. In May 1996, the Company repurchased the 10% interest
       in the project and the agreement  was amended to cancel  Tomen's right to
       purchase an equity interest in funded projects. As of September 30, 1996,
       Tomen has agreed to provide a total of $34.45  million in debt  financing
       to the Company's subsidiaries ($31.8 million of which has been drawn down
       as of September  30, 1996) for  construction  and  operation of its fiber
       optic networks in Southern California, New Mexico, and Arizona. The Tomen
       financing agreements are subject to certain debt covenants. Subsequent to
       September 30, 1996, Tomen has agreed to provide an additional $41 million
       in debt financing for the Company's Hawaiian network.

       occur at the first  calendar  quarter  following the initial  loan.  Upon
       making the first loan request,  the Company will be committed to purchase
       a minimum  of $16.5  million  in  equipment  over  three  years.  Amounts
       borrowed  under the  agreement  will be repaid in  twenty-four  quarterly

       recourse basis.  The Company has established a $1,000 line of credit with
       the financial institution to provide funding for payment of these leases,

     The  Company  has  net   operating   losses  for  income  tax  purposes  of
     approximately  $44,985  available to reduce United States taxable income of
     future years, expiring as follows:

     For United States income tax purposes,  utilization of net operating losses
     may be  subject to  limitation  in the event a change in  ownership  of the
     Company has occurred pursuant to IRC Section 382. However, it is the belief
     of management  that the  likelihood of incurring such a change in ownership
     after  the  Company  became  publicly  held in the U.S.  in  March  1994 is
     minimal.  The Company does not expect to generate sufficient taxable income
     so as to utilize all or a  substantial  portion of such loss  carryforwards
     prior to their expiration and maintains a 100% valuation  allowance to such
     deferred tax assets.

       In 1995,  the  Company  adopted a defined  contribution  401(k) plan (the
       Plan).   Employees  are  eligible  to   participate   in  the  Plan  upon
       commencement  of  service.  Participants  may defer up to 15% of eligible
       compensation.   Currently,   the  Company   does  not  provide   matching
       contributions for the Plan.

       NACT also sponsors a defined  contribution  401(k) plan for employees who
       have  completed  one  year  of  service  and  attained  the  age  of  21.
       Participants may defer up to 15% of eligible  compensation.  NACT, at its
       discretion,  may match  50% of  participant  contributions  up to 7.5% of
       participant  compensation.  NACT made employer contributions to this plan
       of $60, $51 and $32 in the periods  ending  September 30, 1996,  1995 and
       1994, respectively.

       Through September 30, 1996, NACT provided a discretionary  profit sharing
       program  for full  time  employees  who had  completed  one full  year of
       employment.  Under the plan,  10% of the  increase  in  profits  based on
       NACT's previous  highest  retained  earnings balance were allocated among
       employees  determined  on length of  employment  and salary  level at the
       discretion of the Board of Directors.  Contributions  to the program were
       $132,  $171 and $105 for the periods ended  September 30, 1996,  1995 and
       1994, respectively. The program was terminated on September 30, 1996.

   (b) LONG DISTANCE CARRIERS

       The Company is party to various  contracts  with long  distance  carriers
       pursuant to which the Company is committed to minimum  service fees.  The
       average  monthly  minimum  commitments  range  from $1.6  million to $5.1
       million per month over the next three  years.  The  Company  must pay the
       carriers for  differences  between the commitment  amounts and the actual
       amounts billed.

   (c) STOCK OPTION PLANS AND STOCK BONUS AGREEMENT

       Certain employees of the Company are eligible for stock options awards of
       GST stock under various stock option plans. In addition,  certain members
       of  management  are  eligible to receive  stock  awards of GST stock upon
       achievement  of certain  milestones.  Given  that  senior  operating  and
       executive  management are employees of the Company,  compensation expense
       is  recognized  in  the  financial  statements  of  the  Company.   Stock
       compensation  totaled $574,  $-0- and $0 for the periods ended  September
       30, 1996, 1995 and 1994, respectively.


                                                                     (Continued)

   (d) LEGAL PROCEEDINGS

       On August 24, 1995, Aerotel, Ltd. and Aerotel U.S.A., Inc. (collectively,
       "Aerotel")  filed a patent  infringement  suit against NACT alleging that
       telephone  systems  manufactured  and  sold by NACT  incorporate  prepaid
       calling  features  which  infringe  upon a patent  issued to  Aerotel  in
       November  1987.  The  complaint  further  alleges  defamation  and unfair
       competition by NACT and seeks various  damages.  NACT has filed an Answer
       and Counterclaim  denying patent infringement,  committing  defamation or
       unfair  competition and seeks judgment that the Aerotel patent is invalid
       and that Aerotel has misused its patent in  violation of antitrust  laws.
       Based on information  currently  available,  NACT's  management is of the
       opinion  that  there  will be no  material  impact  of  NACT's  financial
       position or results of operations as a result of this suit.  Accordingly,
       no provision  for loss has been  provided in the  accompanying  financial
       statements.

       The Company is involved in various other claims and legal actions arising
       in the ordinary  course of business.  In the opinion of  management,  the
       ultimate  disposition of these matters will not have a material effect on
       the Company's financial position.

   (e) EMPLOYMENT AGREEMENTS

       The Company has entered into  employment  agreements  with key members of
       management.  These  agreements  provide  for  payments  based upon death,
       disability and change of control.  The agreements also contain  covenants
       not to compete.

(10) INFORMATION RELATING TO CONSOLIDATED STATEMENTS OF CASH FLOWS

     Cash used in  operations  includes cash payments for interest of $1,813 and
     $364,  and cash  payments  for taxes of $-0- and $264 for the  years  ended
     September 30, 1996 and 1995, respectively.

     The operations of the Company's  Hawaiian microwave network require the use
     of radio  licenses  from the FCC. Such licenses are owned by PNI, a company
     controlled by the  Company's  Chief  Executive  Officer.  Under  agreements
     between the Company and PNI,  (1) the Company  pays a monthly fee to PNI to
     utilize PNI's licenses for its  communications  traffic and (2) PNI pays an
     equal  monthly fee to the  Company  for the right to utilize the  Company's
     facilities  for  other  communications  traffic  using  up to 10% of  PNI's
     license capacity.

     Under the Tomen facility,  Tomen has the right to act as procurement  agent
     for each network project it finances.  The Company has purchased  equipment

(12) SUBSEQUENT EVENTS (UNAUDITED)

     NACT PUBLIC OFFERING

     In March 1997,  NACT  completed  an initial  public  offering of its common
     stock (the "NACT  Offering"),  pursuant  to which the Company and NACT sold
     one million and two million shares,  respectively,  of NACT's common stock,
     resulting in gross  proceeds to the Company and NACT of $10 million and $20
     million,  respectively.  As a result of the NACT  Offering,  the  Company's
     interest in NACT has been reduced to approximately 63%.

NOTES OFFERING

     In May 1997, GST Equipment Funding, Inc., a wholly-owned  subsidiary of the
     Company  issued $265 million in senior  secured notes due May 1, 2007.  The
     notes bear interest at a rate of 13.25% with semi-annual  interest payments
     due beginning November 1, 1997. Approximately $93.8 million of the proceeds
     have been set aside to fund the first six scheduled interest payments.  The
     remainder  of the  net  proceeds  will  be used  to  purchase  and  install
     telecommunications equipment.

MAGNACOM WIRELESS, LLC

     Magnacom and the Company have entered into a twelve-year reseller agreement
     (the "Magnacom Reseller  Agreement")  pursuant to which (i) the Company has
     been designated a non-exclusive  reseller of PCS telephone  services in the
     markets in which  Magnacom has  obtained  licenses,  and (ii)  Magnacom has
     agreed to use the Company on an exclusive  basis to provide  switched local
     and long distance services, and other enhanced telecommunications services,
     to all of Magnacom's resellers in markets where the Company has operational
     networks.  Magnacom agreed to sell PCS minutes to the Company at five cents
     per minute,  subject to  downward  adjustment  to equal the most  favorable
     rates  offered to  Magnacom's  other  resellers  (but in no event less than
     Magnacom's cost).  Subsequent to September 30, 1996, in connection with the
     Magnacom  Reseller  Agreement,  the Company paid an additional $5.4 million
     for a total of  approximately  $14.4 million as pre-payments for future PCS
     services.

     In addition,  the Company has been granted a conditional  option to acquire
     up to a 99% interest in Magnacom, conditioned upon Magnacom and the Company
     entering  into  an  agreement  for the  construction  and/or  operation  of
     Magnacom's  facilities.  The condition precedent to such option has not yet
     been met. Such option, if and when the condition precedent is met, shall be
     subject to compliance with all applicable FCC regulations relating to prior
     approval  of any  transfer  of control  of PCS  licenses,  including  those
     relating to foreign ownership or control.  Accordingly,  until such time as
     may be permitted by FCC regulations or  administrative  action,  the option
     will be initially limited to a 24% interest in Magnacom.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

GST FUNDING

         The General  Corporation  Law of the State of Delaware  (the  "Delaware
Law") permits indemnification of directors, employees and agents of corporations
under certain  conditions  and subject to certain  limitations.  Pursuant to the
Delaware Law, GST Funding has included in its Certificate of  Incorporation  and
bylaws a provision to  eliminate  the personal  liability of its  directors  for
monetary  damages  for  breach or  alleged  breach of their  duty of care to the
fullest  extent  permitted  by the  Delaware Law and to provide that GST Funding
shall  indemnify its directors and officers to the fullest  extent  permitted by
the Delaware Law.

   
GST USA

         Pursuant to the Delaware  Law, GST USA has included in its  Certificate
of Incorporation  and bylaws a provision to eliminate the personal  liability of
its directors for monetary damages for breach or alleged breach of their duty of
care to the fullest extent permitted by the Delaware Law and to provide that GST
USA shall  indemnify its directors and officers to the fullest extent  permitted
by the Delaware Law.
    

GST

         Except  as  hereinafter  set  forth,  there  is  no  statute,   charter
provision,  by-law,  contract or other  arrangement  under which any controlling
person,  director  or officer of GST is  insured  or  indemnified  in any manner
against liability which he may incur in his capacity as such.

         GST's  authority to indemnify its directors and officers is governed by
the  provisions  of Section  124 of the Canada  Business  Corporations  Act,  as
follows:

         (1) INDEMNIFICATION.  Except in respect of an action by or on behalf of
the  corporation  or body  corporate  to  procure a  judgment  in its  favor,  a
corporation  may  indemnify a director or officer of the  corporation,  a former
director  or  officer  of the  corporation  or a person who acts or acted at the
corporation's  request as a director or officer of a body corporate of which the
corporation  is or was a  shareholder  or  creditor,  and his  heirs  and  legal
representatives,  against all costs,  charges and expenses,  including an amount
paid to settle an action or satisfy a  judgment,  reasonably  incurred by him in
respect of any civil,  criminal or administrative  action or proceeding to which
he is made a party by reason of being or having  been a  director  or officer of
such corporation or body corporate, if

              (a) he acted  honestly  and in good  faith with a view to the best
                  interests of the corporation; and

              (b) in  the  case  of  a  criminal  or  administrative  action  or
                  proceeding  that is  enforced  by a monetary  penalty,  he had
                  reasonable grounds for believing that his conduct was lawful.

              (2)  INDEMNIFICATION IN DERIVATIVE ACTIONS. A corporation may with
the  approval of a court  indemnify a person  referred to in  subsection  (1) in
respect of an action by or on behalf of the  corporation  or body  corporate  to
procure a judgment in its favor,  to which he is made a party by reason of being
or having been a director or an officer of the  corporation  or body  corporate,
against all costs, charges and expenses reasonably incurred by him in connection
with such action if he fulfills the conditions set out in paragraphs  (1)(a) and
(b).

              (3)  INDEMNITY  AS OF  RIGHT.  Notwithstanding  anything  in  this
section,  a person  referred to in subsection  (1) is entitled to indemnity from
the  corporation  in respect  of all  costs,  charges  and  expenses  reasonably
incurred  by him in  connection  with the  defense  of any  civil,  criminal  or
administrative action or proceeding to which he is

                                      II-1

<PAGE>

made a party by reason of being or having  been a  director  or  officer  of the
corporation or body corporate, if the person seeking indemnity

              (a) was  substantially  successful on the merits in his defense of
                  the action or proceeding, and

              (b) fulfills the conditions set out in paragraphs (1)(a) and (b).

              (4) DIRECTORS' AND OFFICERS' INSURANCE. A corporation may purchase
and maintain  insurance for the benefit of any person referred to subsection (1)
against any liability incurred by him

              (a) in his  capacity as a director or officer of the  corporation,
                  except  where the  liability  relates  to his  failure  to act
                  honestly  and in good faith with a view to the best  interests
                  of the corporation; or

              (b) in his  capacity  as a director  or  officer  of another  body
                  corporate  where  he acts or  acted  in that  capacity  at the
                  corporation's  request,  except where the liability relates to
                  his failure to act  honestly  and in good faith with a view to
                  the best interests of the body corporate.

              (5) APPLICATION TO COURT. A corporation or a person referred to in
subsection  (1) may apply to a court for an order  approving an indemnity  under
this  section  and the court may so order and make any  further  order it thinks
fit.

              (6) NOTICE TO DIRECTOR.  An applicant  under  subsection (5) shall
give the  Director  notice of the  application  and the  Director is entitled to
appear and be heard in person or by counsel.

              (7) OTHER NOTICE.  On an  application  under  subsection  (5), the
court may order notice to be given to any  interested  person and such person is
entitled to appear and be heard in person or by counsel.

              GST's by-laws  provide that every  director and officer of GST and
his heirs,  executors,  administrators and other legal personal  representatives
shall be  indemnified  and held  harmless from and against (a) any liability and
all costs,  charges and  expenses  that he sanctions or incurs in respect of any
action,  suit or proceeding that is proposed or commenced  against him for or in
respect of anything  done or permitted by him in respect of the execution of the
duties of his office  and (b) all other  costs,  charges  and  expenses  that he
sustains or incurs in respect of the affairs of GST.

              GST  maintains a  $15,000,000  directors  and  officers  liability
insurance policy.

              GST has also  agreed to  indemnify  each  director  and  executive
officer  pursuant to an  indemnification  agreement  with each such director and
executive officer from and against any and all expenses, losses, claims, damages
and liability  incurred by such director or executive officer for or as a result
of action taken or not taken while such director or executive officer was acting
in his capacity as a director, officer, employee or agent of the Company.

ITEM 22. UNDERTAKINGS.

(a)      The undersigned registrants hereby undertake:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

         (i) To include  any  prospectus  required  by Section  10(a)(3)  of the
Securities Act of 1933;

         (ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration  statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent

                                      II-3

<PAGE>

a fundamental change in the information set forth in the registration statement.
Notwithstanding the foregoing,  any increase or decrease in volume of securities
offered (if the total dollar value of  securities  offered would not exceed that
which  was  registered)  and any  deviation  from  the  low or  high  and of the
estimated  maximum  offering  range may be reflected  in the form of  prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume and price set forth in the  "Calculation of Registration  Fee"
table in the effective registration statement.

         (iii) To include any material  information  with respect to the plan of
distribution  not  previously  disclosed  in the  registration  statement or any
material change to such information in the registration statement.

         (2) That,  for the  purpose  of  determining  any  liability  under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such  securities at that time shall be deemed to be the initial BONA
FIDE offering thereof.

   
         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.
    

         (4) That prior to any public  reoffering of the  securities  registered
hereunder  through the use of a prospectus which is a part of this  registration
statement,  by any person or party who is deemed to be an underwriter within the
meaning  of Rule  145(c)  under the  Securities  Act of 1933,  as  amended  (the
"Securities  Act"), the issuer  undertakes that such reoffering  prospectus will
contain the  information  called for by the  applicable  registration  form with
respect to reofferings by persons who may be deemed underwriters, in addition to
the information called for by the other Items of the applicable form.

         (5) That every  prospectus  (i) that is filed pursuant to paragraph (4)
immediately preceding, or (ii) that purports to meet the requirements of section
10(a)(3) of the  Securities  Act and is used in  connection  with an offering of
securities subject to Rule 415 under the Securities Act, will be filed as a part
of an amendment to the  registration  statement  and will not be used until such
amendment is  effective,  and that,  for purposes of  determining  any liability
under the Securities Act, each such post-effective  amendment shall be deemed to
be a new registration  statement relating to the securities offered therein, and
the offering of such  securities  at that time shall be deemed to be the initial
bona fide offering thereof.

(b) Insofar as indemnification  for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
registrants pursuant to the foregoing provisions,  or otherwise, the registrants
have been advised that in the opinion of the Commission such  indemnification is
against  public  policy as expressed in the  Securities  Act and is,  therefore,
enforceable.  In the  event  that  a  claim  for  indemnification  against  such
liabilities  (other than the payment by the registrants of expenses  incurred or
paid by a director,  officer or  controlling  person of the  registrants  in the
successful  defense of any  action,  suit or  proceedings)  is  asserted by such
director,  officer or controlling person in connection with the securities being
registered,  the  registrants  will,  unless in the  opinion of its  counsel the
matter  has  been  settled  by  controlling  precedent,  submit  to a  court  of
appropriate  jurisdiction the question whether  indemnification by it is against
public  policy as  expressed in the  Securities  Act and will be governed by the
final adjudication of such issue.

(c) The  undersigned  registrants  hereby  undertake  to respond to requests for
information  that is incorporated  by reference into the prospectus  pursuant to
Items 4, 10(b),  11 or 13 of this Form,  within one  business  day of receipt of
such  request,  and to send the  incorporated  documents  by first class mail or
other equally  prompt means.  This includes  information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

(d) The  undersigned  registrants  hereby  undertake  to  supply  by  means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the registration statement when it became effective.

(e)  The  undersigned   registrants  hereby  undertake  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
registrants'  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable,  each filing of an employee benefit
plan's annual report pursuant to

                                      II-4

<PAGE>

Section 15(d) of the Securities  Exchange Act of 1934) that is  incorporated  by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

benefit. If the GCL is amended to authorize corporate action further eliminating
or limiting  the  personal  liability  of  directors,  then the  liability  of a

permitted  by the  GCL,  as so  amended.  Any  repeal  or  modification  of this
Paragraph A by the stockholders of the

repeal or modification.

                           B. (1) Each  person  who was or is made a party or is
threatened  to be  made a  party  to or is  involved  in any  action,  suit,  or
proceeding,   whether   civil,   criminal,   administrative   or   investigative
(hereinafter a  "proceeding"),  by reason of the fact that he or she or a person
of whom he or she is the legal  representative  is or was a  director,  officer,
employee or agent of the  Corporation or is or was serving at the request of the
Corporation,  as a director, officer or employee or agent of another corporation
or of a partnership, joint venture, trust or other enterprise, including service
with respect to employee benefit plans,  whether the basis of such proceeding is
alleged action in an official capacity as a director, officer, employee or agent
or in any other  capacity  while  serving as a  director,  officer,  employee or
agent,  shall be indemnified and held harmless by the Corporation to the fullest
extent  authorized  by the GCL as the same  exists or may  hereafter  be amended
(but, in the case of any such amendment,  only to the extent that such amendment
permits the Corporation to provide broader  indemnification rights than said law
permitted  the  Corporation  to provide  prior to such  amendment),  against all
expense, liability and loss (including attorneys' fees, judgments,  fines, ERISA
excise  taxes  or  penalties  and  amounts  paid or to be  paid  in  settlement)
reasonably incurred or suffered by such person in connection  therewith and such
indemnification  shall  continue as to a person who has ceased to be a director,
officer,  employee  or agent and shall inure to the benefit of his or her heirs,
executors  and  administrators;  provided,  however,  that except as provided in
paragraph (2) of this Paragraph B with respect to proceedings seeking to enforce
rights to  indemnification,  the  Corporation  shall  indemnify  any such person
seeking  indemnification  in  connection  with a  proceeding  (or part  thereof)
initiated  by  such  person  only if  such  proceeding  (or  part  thereof)  was
authorized  by  the  Board  of  Directors  of  the  Corporation.  The  right  to
indemnification  conferred  in this  Paragraph  B shall be a contract  right and
shall include the right to be paid by the Corporation  the expenses  incurred in
defending  any such  proceeding in advance of its final  disposition;  provided,
however,  that if the GCL requires,  the payment of such expenses  incurred by a
director or officer in his or her  capacity as a director or officer (and not in
any other  capacity) in which  service was or is rendered by such person while a
director  or  officer,  including,  without  limitation,  service to an employee
benefit plan) in advance of the final disposition of a proceeding, shall be made
only upon delivery to the  Corporation of an undertaking by or on behalf of such
director or officer to repay all amounts so advanced if it shall  ultimately  be
determined that such director or officer is not entitled to be indemnified under
this Paragraph B or otherwise.

                           (2) If a claim under  paragraph (1) of this Paragraph
B is not paid in full by the  Corporation  within  thirty  days  after a written
claim  has  been  received  by the  Corporation,  the  claimant  may at any time
thereafter  bring suit against the  Corporation  to recover the unpaid amount of
the claim and, if successful in whole or in part, the claimant shall be entitled
to be paid also the expense of prosecuting  such claim. It shall be a defense to
any such action  (other than an action  brought to enforce a claim for  expenses
incurred in defending any proceeding in advance of its final  disposition  where
the  required  undertaking,  if  any  is  required,  has  been  tendered  to the
Corporation)  that the claimant has not met the  standards of conduct which make
it permissible  under the GCL for the  Corporation to indemnify the claimant for
the  amount  claimed  but the  burden of proving  such  defense  shall be on the
Corporation.  Neither the  failure of the  Corporation  (including  its Board of
Directors,   independent   legal  counsel  or   stockholders)  to  have  made  a
determination  prior to the commencement of such action that  indemnification of
the  claimant  is  proper  in the  circumstances  because  he or she has met the
applicable standard of conduct set forth in the GCL, nor an actual determination
by the Corporation (including its Board of Directors,  independent legal counsel
or  stockholders)  that the  claimant  has not met such  applicable  standard of
conduct,  shall be a defense  to the  action or  create a  presumption  that the
claimant has not met the applicable standard of conduct.

                           (3) The right to  indemnification  and the payment of
expenses  incurred in defending a proceeding in advance of its final disposition
conferred  in this  Paragraph B shall not be  exclusive of any other right which
any person may have or hereafter  acquire  under any  statute,  provision of the
certificate  of  incorporation,  By-Laws,  agreement,  vote of  stockholders  or
disinterested directors or otherwise.

                           (4) The  Corporation may maintain  insurance,  at its
expense, to protect itself and any director,  officer,  employee or agent of the
Corporation or another corporation,  partnership,  joint venture, trust or other
enterprise  against  any  expense,   liability  or  loss,  whether  or  not  the
Corporation  would have the power to indemnify such person against such expense,
liability or loss under the GCL.

                           (5) The  Corporation  may,  to the extent  authorized
from time to time by the Board of  Directors,  grant rights to  indemnification,
and rights to be paid by the Corporation for the expenses  incurred in defending
any  proceeding  in  advance  of its  final  disposition,  to any  agent  of the
Corporation  to the fullest  extent of the  provisions of this  Paragraph B with
respect  to the  indemnification  and  advancement  of  expenses  of  directors,
officers and employees of the Corporation.

                  SEVENTH:  In  addition to any other  considerations  which the
Board of Directors  may lawfully take into account,  in  determining  whether to
take or to  refrain  from  taking  corporate  action  on any  matter,  including
proposing  any  matter  to the  stockholders  of the  Corporation,  the Board of
Directors may take into account the long-term as well as short-term interests of
the  Corporation  and its  stockholders  (including the  possibility  that these
interests may be best served by the continued  independence of the Corporation),
the interests of creditors, customers, employees and other constituencies of the
Corporation and its  subsidiaries  and the effect upon  communities in which the
Corporation and its subsidiaries do business.

                  EIGHTH:  In  furtherance  and not in  limitation of the powers
conferred by law or in this Certificate of Incorporation, the Board of Directors
(and any committee of the Board of Directors)  is expressly  authorized,  to the
extent  permitted  by law,  to take such  action or actions as the Board or such
committee may determine to be reasonably necessary or desirable to (A) encourage
any person to enter into negotiations with the Board of Directors and management
of the Corporation with respect to any transaction  which may result in a change
in control of the  Corporation  which is proposed or initiated by such person or
(B) contest or oppose any such transaction  which the Board of Directors or such
committee determines to be unfair, abusive or otherwise undesirable with respect
to the Corporation and its business, assets or properties or the stockholders of
the Corporation,  including,  without  limitation,  the adoption of plans or the
issuance of rights, options, capital stock, notes, debentures or other evidences
of indebtedness or other securities of the Corporation,  which rights,  options,
capital stock, notes,  evidences of indebtedness and other securities (i) may be
exchangeable  for or convertible into cash or other securities on such terms and
conditions  as may be  determined  by the Board or such  committee  and (ii) may
provide for the treatment of any holder or class of holders  thereof  designated
by the  Board of  Directors  or any such  committee  in  respect  of the  terms,
conditions,  provisions and rights of such  securities  which is different from,
and unequal to, the terms,  conditions,  provisions and rights applicable to all
other holders thereof.

                  NINTH:  The  Corporation  reserves the right to amend,  alter,
change or repeal any provision  contained in this Certificate of  Incorporation,
and any other provisions  authorized by the laws of the State of Delaware at the
time in force may be added or inserted,  subject to the limitations set forth in
this  Certificate of Incorporation  and in the manner now or hereafter  provided
herein by statute,  and all rights,  preferences  and  privileges  of whatsoever
nature conferred upon stockholders, directors or any other persons whomsoever by
and pursuant to this

Certificate  of  Incorporation  in its  present  form or as amended  are granted
subject to the rights reserved in this Article NINTH.

                  IN WITNESS  WHEREOF,  I have hereunto set my hand this 1st day
of July, 1994.

                                    ARTICLE I

                                  STOCKHOLDERS

                  SECTION   1.1.   ANNUAL   MEETINGS.   An  annual   meeting  of
stockholders to elect directors and transact such other business as may properly
be  presented  to the  meeting  shall  be held at such  place  as the  Board  of
Directors may from time to time fix, if that day shall be a legal holiday in the
jurisdiction  in which  the  meeting  is to be held,  then on the next day not a
legal holiday or as soon thereafter as may be practical, determined by the Board
of Directors.

                  SECTION  1.2.   SPECIAL   MEETINGS.   A  special   meeting  of
stockholders may be called at any time by the Board of Directors or the Chairman
shall be called by any of them or by the  Secretary  upon  receipt  of a written
request to do so  specifying  the matter or matters,  appropriate  for action at
such a meeting, proposed to be presented at the meeting and signed by holders of
record of a majority  of the shares of stock that would be  entitled to be voted
on such  matter or matters if the meeting  were held on the day such  request is
received  and the record date for such meeting were the close of business on the
preceding  day. Any such  meeting  shall be held at such time and at such place,
within or without the State of Delaware,  as shall be  determined by the body or
person  calling  such  meeting  and as shall be  stated  in the  notice  of such
meeting.

                  SECTION   1.3.   NOTICE  OF  MEETING.   For  each  meeting  of
stockholders written notice shall be given stating the place, date and hour and,
in the case of a special meeting,  the purpose or purposes for which the meeting
is called.  Except as otherwise  provided by Delaware law, the written notice of
any meeting shall be given not less than 10 or more than 60 days before the date
of the meeting to each stockholder  entitled to vote at such meeting. If mailed,
notice  shall be deemed to be given when  deposited  in the United  States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the Corporation.

                  SECTION 1.4. QUORUM.  Except as otherwise required by Delaware
law or the Certificate of Incorporation,  the holders of record of a majority of
the shares of stock entitled to be voted


<PAGE>

present in person or represented by proxy at a meeting shall constitute a quorum
for the  transaction of business at the meeting,  but in the absence of a quorum
the holders of record  present or  represented by proxy at such meeting may vote
to adjourn the meeting from time to time, without notice other than announcement
at the meeting, until a quorum is obtained. At any such adjourned session of the
meeting at which there shall be present or represented  the holders of record of
the requisite  number of shares,  any business may be transacted that might have
been transacted at the meeting as originally called.

                  SECTION  1.5.  CHAIRMAN  AND  SECRETARY  AT  MEETING.  At each
meeting of stockholders the Chairman, or in his absence the person designated in
writing  by the  Chairman,  or if no  person  is so  designated,  then a  person
designated by the Board of Directors,  shall preside as chairman of the meeting;
if no person is so  designated,  then the  meeting  shall  choose a chairman  by
plurality  vote.  The  Secretary,  or in his absence a person  designated by the
chairman of the meeting, shall act as secretary of the meeting.

                  SECTION 1.6. VOTING;  PROXIES. Except as otherwise provided by
Delaware law or the Certificate of Incorporation,  and subject to the provisions
of Section 1.10:

                           (a) Each  stockholder  shall at every  meeting of the
stockholders  be  entitled  to one vote for each share of capital  stock held by
him.

                           (b) Each stockholder entitled to vote at a meeting of
stockholders  or to express  consent or dissent to  corporate  action in writing
without a meeting  may  authorize  another  person or  persons to act for him by
proxy, but no such proxy shall be voted or acted upon after three years from its
date, unless the proxy provides for a longer period.

                           (c) Directors shall be elected by a plurality vote.

                           (d) Each matter,  other than  election of  directors,
properly  presented  to any meeting  shall be decided by a majority of the votes
cast on the matter.

                           (e) Election of  directors  and the vote on any other
matter  presented to a meeting shall be by written  ballot only if so ordered by
the  chairman of the meeting or if so requested  by any  stockholder  present or
represented by proxy at the meeting entitled to vote in such election or on such
matter, as the case may be.

                  SECTION 1.7. ADJOURNED MEETINGS. A meeting of stockholders may
be  adjourned  to another  time or place as  provided  in Section 1.4 or 1.6(d).
Unless the Board of Directors  fixes a new record date,  stockholders  of record
for an adjourned meeting shall be as originally  determined for the meeting from
which the adjournment was taken. If the adjournment is for more than 30 days, or
if after the adjournment a new record date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be

                                       -2-

<PAGE>
given to each  stockholder of record entitled to vote. At the adjourned  meeting
any business may be transacted that might have been transacted at the meeting as
originally called.

                  SECTION 1.8.  CONSENT OF STOCKHOLDERS IN LIEU OF MEETING.  Any
action that may be taken at any annual or special meeting of stockholders may be
taken  without a meeting,  without prior notice and without a vote, if a consent
in writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary  to  authorize  or take such  action at a meeting  at which all shares
entitled to vote thereon  were  present and voted.  Notice of the taking of such
action shall be given promptly to each stockholder that would have been entitled
to vote thereon at a meeting of stockholders and that did not consent thereto in
writing.

                  SECTION 1.9. LIST OF  STOCKHOLDERS  ENTITLED TO VOTE. At least
10 days before every meeting of stockholders a complete list of the stockholders
entitled to vote at the meeting,  arranged in alphabetical order and showing the
address of each  stockholder and the number of shares  registered in the name of
each stockholder,  shall be prepared and shall be open to the examination of any
stockholder  for any purpose germane to the meeting,  during  ordinary  business
hours, for a period of at least 10 days prior to the meeting,  at a place within
the city where the meeting is to be held.  Such list shall be produced  and kept
at the time and place of the  meeting  during the whole time  thereof and may be
inspected by any stockholder who is present.

                  SECTION  1.10.  FIXING  OF  RECORD  DATE.  In  order  that the
Corporation may determine the  stockholders  entitled to notice of or to vote at
any meeting of stockholders or any adjournment thereof, or to express consent to
corporate action in writing without a meeting, or entitled to receive payment of
any dividend or other  distribution  or allotment of any rights,  or entitled to
exercise any rights in respect of any change, conversion or exchange of stock or
for the purpose of any other lawful  action,  the Board of Directors may fix, in
advance,  a record  date,  which  shall not be more than 60 or less than 10 days
before  the date of such  meeting,  nor  more  than 60 days  prior to any  other
action. If no record date is fixed, the record date for determining stockholders
entitled  to notice of or to vote at a meeting of  stockholders  shall be at the
close of business on the day next  preceding  the day on which  notice is given,
or, if notice is waived,  at the close of business on the day next preceding the
day on which the meeting is held; the record date for  determining  stockholders
entitled to express  consent to corporate  action in writing  without a meeting,
when no prior action by the Board of Directors is necessary, shall be the day on
which the first written consent is expressed;  and the record date for any other
purpose  shall be at the  close of  business  on the day on which  the  Board of
Directors adopts the resolution relating thereto.

                                    DIRECTORS

                  SECTION   2.1.   NUMBER;   TERM  OF  OFFICE;   QUALIFICATIONS;
VACANCIES.  The number of  directors  that shall  constitute  the whole Board of
Directors  shall be five,  which  number  may be  changed  from  time to time as
determined by action of the Board of Directors taken by the affirmative  vote of
a majority of the whole Board of  Directors.  Directors  shall be elected at the
annual meeting of stockholders to hold office,  subject to Sections 2.2 and 2.3,
until  the next  annual  meeting  of  stockholders  and until  their  respective
successors are elected and qualified.  Vacancies and newly created directorships
resulting from any increase in the authorized  number of directors may be filled
by a majority of the directors then in office,  although less than a quorum,  or
by the sole remaining  director,  and the directors so chosen shall hold office,
subject to Sections 2.2 and 2.3, until the next annual  meeting of  stockholders
and until their respective successors are elected and qualified.

                  SECTION 2.2. RESIGNATION.  Any director of the Corporation may
resign at any time by giving written notice of such  resignation to the Board of
Directors  or  the  Chairman  or the  Secretary  of the  Corporation.  Any  such
resignation  shall take effect at the time  specified  therein or, if no time be
specified,  upon  receipt  thereof  by  the  Board  of  Directors  or one of the
above-named  officers;  and, unless  specified  therein,  the acceptance of such
resignation  shall  not be  necessary  to make it  effective.  When  one or more
directors shall resign from the Board of Directors effective at a future date, a
majority of the directors then in office,  including those who have so resigned,
shall have power to fill such  vacancy or  vacancies,  the vote  thereon to take
effect when such resignation or resignations  shall become  effective,  and each
director so chosen shall hold office as provided in these By-Laws in the filling
of other vacancies.

                  SECTION  2.3.  REMOVAL.  Any  one  or  more  directors  may be

meetings of the Board of Directors shall be held at such time and at such place,
within or without the State of Delaware, as the Board of Directors may from time

if given,  need not  specify  the  purposes  thereof.  A meeting of the Board of
Directors  may be held without  notice  immediately  after an annual  meeting of
stockholders at the same place as that at which such meeting was held.

                  SECTION 2.5.  SPECIAL  MEETINGS;  NOTICE. A special meeting of
the Board of Directors may be called at any time by the Board of Directors,  its

such a meeting,  proposed to be  presented at the meeting and signed by at least
two  directors.  Any such meeting  shall be held at such time and at such place,
within or without the State of Delaware,  as shall be  determined by the body or
person calling such meeting.  Notice of such meeting  stating the time and place
thereof  shall be given (a) by deposit of the notice in the United  States mail,
first  class,  postage  prepaid,  at least two days before the day fixed for the
meeting  addressed  to  each  director  at  his  address  as it  appears  on the
Corporation's  records  or at  such  other  address  as the  director  may  have

serve at its  pleasure as Chairman  of the Board.  Each  meeting of the Board of
Directors  shall be presided over by the Chairman of the Board or in his absence
by the President,  if a director, or if neither is present by such member of the
Board of Directors as shall be chosen at the meeting.  The Secretary,  or in his

meeting, until such time as a quorum is present. Except as otherwise required by
the Certificate of Incorporation or the By-Laws, the vote of the majority of the
directors  present at a meeting at which a quorum is present shall be the act of
the Board of Directors.

                  SECTION  2.8.  MEETING BY  TELEPHONE.  Members of the Board of
Directors or of any committee  thereof may  participate in meetings of the Board
of Directors or of such  committee by means of  conference  telephone or similar
communications  equipment  by means of which all  persons  participating  in the
meeting can hear each other, and such participation shall constitute presence in
person at such meeting.

                  SECTION  2.9.  ACTION  WITHOUT   MEETING.   Unless   otherwise
restricted by the Certificate of Incorporation, any action required or permitted

may be taken  without a meeting if all members of the Board of  Directors  or of
such  committee,  as the case may be, consent thereto in writing and the writing
or writings are filed with the minutes of  proceedings of the Board of Directors
or of such committee.

                  SECTION  2.10.  EXECUTIVE AND OTHER  COMMITTEES.  The Board of
Directors  may,  by  resolution  passed  by a  majority  of the  whole  Board of
Directors,  designate an Executive Committee one or more other committees,  each
such committee to consist of one or more directors as the Board of Directors may
from time to time determine.  Any such committee, to the extent provided in such
resolution  or  resolutions,  shall  have and may  exercise  all the  powers and
authority  of the Board of  Directors  in the  management  of the  business  and
affairs of the  Corporation,  including  the power to authorize  the seal of the
Corporation  to be  affixed  to all  papers  that  may  require  it but no  such
committee  shall have such power of  authority  in  reference  to  amending  the
Certificate of Incorporation,  adopting an agreement of merger or consolidation,
recommending  to  the  stockholders  the  sale,  lease  or  exchange  of  all or
substantially all of the Corporation's property and assets,  recommending to the

                                  MISCELLANEOUS

                  SECTION 5.1.  INDEMNITY.  (a) The Corporation shall indemnify,
subject to the  requirements  of subsection (d) of this Section,  any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative  (other than an action by or in the right of the  Corporation),
by reason of the fact that he is or was a director,  officer,  employee or agent
of the Corporation,  or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other  enterprise,  against  expenses  (including  attorneys'
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred by him in connection  with such action,  suit or proceeding if he acted
in good faith and in a manner he reasonably  believed to be in or not opposed to
the best interests of the  Corporation  and, with respect to any criminal action
or proceeding,  had no reasonable cause to believe his conduct was unlawful. The
termination of any action,  suit or proceeding by judgment,  order,  settlement,
conviction or upon a plea of nolo  contendere or its  equivalent,  shall not, of
itself,  create a presumption that the person did not act in good faith and in a
manner  which  he  reasonably  believed  to be in or not  opposed  to  the  best
interests  of the  Corporation  and,  with  respect  to any  criminal  action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

                           (b) The Corporation  shall indemnify,  subject to the
requirements of subsection (d) of this Section, any person who was or is a party
or is  threatened  to be made a party to any  threatened,  pending or  completed
action or suit by or in the right of the  Corporation  to procure a judgment  in
its favor by reason of the fact that he is or was a director,  officer, employee
or  agent  of  the  Corporation  or is or was  serving  at  the  request  of the
Corporation as a director,  officer,  employee or agent of another  corporation,
partnership,   joint  venture,  trust  or  other  enterprise,  against  expenses
(including   attorneys'  fees)  actually  and  reasonably  incurred  by  him  in
connection  with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the  Corporation and except that no  indemnification  shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the Corporation unless and only to the extent that
the Court of Chancery of the State of Delaware or the court in which such action
or  suit  was  brought  shall  determine  upon  application  that,  despite  the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and  reasonably  entitled to indemnity for such expenses  which
the Court of  Chancery  of the State of  Delaware or such other court shall deem
proper.

                           (c) To the extent that a director,  officer, employee
or agent of the Corporation,  or a person serving in any other enterprise at the
request of the  Corporation,  has been  successful on the merits or otherwise in
defense of any action,  suit or proceeding referred to in subsection (a) and (b)
of this  Section,  or in  defense  of any claim,  issue or matter  therein,  the
Corporation  shall indemnify him against  expenses  (including  attorneys' fees)
actually and reasonably incurred by him in connection therewith.

                           (d) Any indemnification under subsections (a) and (b)
of this Section  (unless  ordered by a court)  shall be made by the  Corporation
only  as   authorized   in  the  specific   case  upon  a   determination   that
indemnification  of the  director,  officer,  employee or agent is proper in the
circumstances because he has met the applicable standard of conduct set forth in
subsections (a) and (b) of this Section. Such determination shall be made (1) by
the  Board  of  Directors  by a  majority  vote of a  quorum  consisting  of the
directors who are not parties to such action, suit or proceeding, or (2) if such
a quorum is not  obtainable,  or, even if  obtainable a quorum of  disinterested
directors,  or (3) by independent legal counsel in a written opinion,  or (4) by
the stockholders.

                           (e)  Expenses   incurred  by  a  director,   officer,
employee or agent in defending a civil or criminal  action,  suit or  proceeding
may be paid by the  Corporation  in  advance  of the final  disposition  of such
action,  suit or proceeding as authorized by the Board of Directors upon receipt
of an undertaking by or on behalf of the director, officer, employee or agent to
repay such amount if it shall  ultimately be determined  that he is not entitled
to be indemnified by the Corporation as authorized in this Section.

                           (f) The  indemnification  and advancement of expenses
provided by or granted pursuant to, the other  subsections of this Section shall
not  limit  the  Corporation  from  providing  any  other   indemnification   or
advancement of expenses permitted by law nor shall it be deemed exclusive of any
other rights to which those seeking  indemnification  may be entitled  under any
by-law, agreement, vote of stockholders or disinterested directors or otherwise,
both as to action in his official  capacity and as to action in another capacity
while holding such office.

                           (g)  The   Corporation   may  purchase  and  maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent  of  the  Corporation,  or who is or was  serving  at the  request  of the
Corporation as a director,  officer,  employee or agent of another  corporation,
partnership,  joint  venture,  trust or other  enterprise  against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his  status as such,  whether  or not the  Corporation  would  have the power to
indemnify him against such liability under the provisions of this Section.

                           (h) The  indemnification  and advancement of expenses
provided by, or granted pursuant to this section shall, unless

                                      -10-

<PAGE>

otherwise provided when authorized or ratified,  continue as to a person who has
ceased to be a  director,  officer,  employee  or agent  and shall  inure to the
benefit of the heirs, executors and administrators of such a person.

                           (i) For the purposes of this  Section,  references to
"the Corporation" shall include, in addition to the resulting  corporation,  any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued,  would
have had power and authority to indemnify its directors,  officers, employees or
agents, so that any person who is or was a director,  officer, employee or agent
of such  constituent  corporation,  or is or was  serving at the request of such
constituent  corporation  as a director,  officer,  employee or agent of another
corporation,  partnership, joint venture, trust or other enterprise, shall stand
in the same  position  under the  provisions of this Section with respect to the
resulting  or  surviving  corporation  as he would  have  with  respect  to such
constituent corporation if its separate existence had continued.

                           (j) This  Section 5.1 shall be  construed to give the
Corporation the broadest power  permissible by the Delaware General  Corporation
Law, as it now stands and as heretofore amended.

                  SECTION 5.2. WAIVER OF NOTICE.  Whenever notice is required by
the  Certificate of  Incorporation,  the By-Laws or any provision of the General
Corporation Law of the State of Delaware,  a written waiver  thereof,  signed by
the person  entitled to notice,  whether  before or after the time  required for
such notice,  shall be deemed equivalent to notice.  Attendance of a person at a
meeting  shall  constitute a waiver of notice of such  meeting,  except when the
person attends a meeting for the express purpose of objecting,  at the beginning
of the meeting,  to the  transaction of any business  because the meeting is not
lawfully  called or convened.  Neither the business to be transacted at, nor the
purpose of, any regular or special  meeting of the  stockholders,  directors  or
members of a committee of directors  need be specified in any written  waiver of
notice.

                  SECTION 5.3.  FISCAL YEAR. The fiscal year of the  Corporation
shall  start on such  date as the  Board of  Directors  shall  from time to time
prescribe.

                  SECTION 5.4.  CORPORATE  SEAL.  The corporate seal shall be in
such form as the Board of  Directors  may from time to time  prescribe,  and the
same may be used by causing it or a facsimile thereof to be impressed or affixed
or in any other manner reproduced.
