(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.  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 special purpose
finance subsidiary of GST, and GST USA and GST are each holding companies.

         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 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


<PAGE>
(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").  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 third parties,  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 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 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


<PAGE>
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 and  Washington.  In addition,  the Company has
networks under  construction  which,  when  completed,  will 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  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 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 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.  Tomen has agreed in
principle to provide the Company with an  additional  $41.0 million of financing
under the Tomen Facility for the Hawaiian  inter-island  network and terrestrial
fiber optic  facilities  and in  connection  with such  financing  will purchase
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 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 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 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 plans capital  expenditures of $225.0 to $250.0 million for
Fiscal  1997  and  $150.0  million  for  Fiscal  1998.  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,
approximately  $41.5  million was used to refinance  intercompany  indebtedness,
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 as of June 30,  1997,  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.

         The  Company's  principal  executive  offices  are located at 4317 N.E.
Thurston  Way,  Vancouver,  Washington  98662  and its  phone  number  is  (360)
254-4700.

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

                                   the  corresponding  Old Notes.  The Notes are
                                   secured by a first priority security interest
                                   in the Pledged  Securities  and in the Pledge
                                   Account  and  by a  first  priority  security

                                   Upon written  request from GST Funding to the
                                   Trustee,  Pledged Securities will be released
                                   from the  Pledge  Account in order to finance
                                   the cost (including,  without limitation, the
                                   cost of  design,  development,  construction,
                                   acquisition,  installation or integration) of
                                   Acquired  Equipment (the "Acquired  Equipment
                                   Cost");  provided  that the  cost of  design,
                                   development,  construction,  installation and
                                   integration of the Acquired  Equipment  shall
                                   not  exceed  50%  of the  aggregate  Acquired
                                   Equipment   Cost.    Immediately   upon   the
                                   acquisition  of any 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 will  purchase  the  Acquired
                                   Equipment  from  GST  Funding  for an  amount
                                   equal to the Acquired Equipment Cost and will
                                   issue  a  senior  secured   promissory   note
                                   guaranteed  by GST in an amount  equal to the
                                   Acquired   Equipment   Cost  payable  to  GST
                                   Funding  (an   "Intercompany   Note").   Each
                                   Intercompany  Note  will  mature  on May  13,
                                   2000. GST Funding will grant a first priority
                                   security  interest in all Intercompany  Notes
                                   to the Trustee for the benefit of the holders
                                   of the Notes.  The Trustee and the holders of
                                   the Notes will be entitled to foreclose  upon
                                   the Initial Note, the Intercompany  Notes and
                                   the Acquired Equipment upon the occurrence of
                                   an Event of  Default  under  the  Notes.  See
                                   "Risk  Factors --  Insufficiency  of Acquired
                                   Equipment   to   Satisfy   the   Notes   upon
                                   Liquidation."

Optional Redemption..............  The Notes will be redeemable at the option of
                                   GST USA, in whole or in part,  at any time or

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.

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
                                   -- Additional Amounts."

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."

Change of Control................  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  the New Notes --  Repurchase of
                                   Notes Upon Change of Control."

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  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,  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. See "Risk Factors --
                                   Substantial   Indebtedness,"   "--   Possible
                                   Inability  to  Service   Indebtedness,"   "--
                                   Structure  of GST  Funding,  GST USA and GST;
                                   Secured Indebtedness;  Ranking of Notes," and
                                   "Description  of  Certain   Indebtedness  and
                                   Redeemable Preferred Shares."

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 GST
                                   USA)  to:  incur   additional   indebtedness;
                                   create   liens;   engage  in   sale-leaseback
                                   transactions;    pay    dividends   or   make
                                   distributions in respect of their

                                   assets; create restrictions on the ability of
                                   Restricted   Subsidiaries   to  make  certain
                                   payments;  issue  or sell  capital  stock  of
                                   Restricted    Subsidiaries;     enter    into
                                   transactions with shareholders or affiliates;
                                   and   consolidate,   merge  or  sell  all  or
                                   substantially   all  of  their  assets.   See
                                   "Description of the New Notes -- Covenants."

Settlement at DTC................  Transfers of Notes  between  participants  in
                                   The Depository  Trust Company ("DTC") will be
                                   effected in the  ordinary  way in  accordance
                                   with  DTC  rules  and  will  be   settled  in

                                  RISK FACTORS

         See "Risk  Factors"  beginning at page 14 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
and  negative  EBITDA  of  $33.9  million  for  Fiscal  1996  and a net  loss of
approximately  $67.3  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.  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 analagous  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  expects  to make  capital  expenditures  of  $225.0 to $250.0
million  during Fiscal 1997.  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.
Thereafter, the Company expects to require additional



                                      -14-
<PAGE>
financing.  However, 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
sooner than  currently  anticipated.  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. Tomen has agreed in principle to provide the Company with
an  additional  $41.0  million of  financing  under the Tomen  Facility  for the
Hawaiian  inter-island  network  and  terrestrial  fiber optic  facilities.  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



                                      -15-
<PAGE>
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 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.



                                      -16-
<PAGE>
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 AND GST TO GUARANTEE 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.  The failure of GST USA to assume the
Notes,  or of GST to guarantee  the Notes,  would result in a default  under the
Notes.  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.



                                      -17-
<PAGE>
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.  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 carried on the  Company's
network.  Until such  time,  the  Company  will rely on ILECs 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 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  additional  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



                                      -18-
<PAGE>
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  the  Company  presently  has  $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.

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."



                                      -19-
<PAGE>
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



                                      -20-

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.

     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



                                      -21-
<PAGE>
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.

     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



                                      -22-


<PAGE>
"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.  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.

POSSIBLE ADVERSE LITIGATION OUTCOME

     An action was commenced  against NACT  alleging that its telephone  systems
incorporating prepaid debit card features infringe upon a patent issued in 1987.
An unfavorable  decision in this action could have a material  adverse effect on
the Company. See "Business -- Legal Proceedings."

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



                                      -23-
<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 directors and officers and
certain of the Company's  professionals are residents of Canada. As a result, it
may be difficult for U.S.  noteholders  to effect  service of process within the
United   States  upon  the  Company  or  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. The Company has been
advised  that there is  substantial  doubt as to 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



                                      -24-
<PAGE>
from those projected in the  forward-looking  statements as a result of the risk
factors set forth above.  The words,  "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.



                                      -25-
<PAGE>
                               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

                                      -26-
<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.



                                      -27-
<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.

                                      -28-
<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.



                                      -29-


<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
     sole 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 sole 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  sole  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



                                      -31-
<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 $41.5
million was utilized to refinance intercompany indebtedness, 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 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.

(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  $41.5  million  was used to
refinance  intercompany  indebtedness,  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.  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.

                                   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 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.  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
expand and interconnect  its networks and broaden its service  offerings and may
consummate additional acquisitions.



                                      -36-
<PAGE>
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 network.  Until such time, the Company will rely on the ILEC to
originate and terminate a significant portion of its



                                      -37-
<PAGE>
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


                                      -39-
<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.



                                      -40-
<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.



                                      -41-

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 and $192.7 million for the nine month periods ended June 30, 1997
and 1996, respectively.  The Company's net cash used in operating and investment
activities was $299.9 million and $75.2 million for the nine month periods ended
June 30, 1997 and 1996, respectively.

         Capital  expenditures  for the nine months ended June 30, 1997 and 1996
were  $168.4  million and $44.0  million,  respectively.  The Company  estimates
capital  expenditures  of between  $225 million and $250 million for Fiscal 1997
and $150 million for Fiscal 1998. 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.  Continued
significant  capital  expenditures  are  expected  to  be  made  thereafter.  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 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 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 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."

<PAGE>
         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  $41.5  million was used to refinance
intercompany  indebtedness,  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.  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.

         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 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.

                                MATERIAL CHANGES

         In May 1997,  GST sold  $265,000,000  of the Old Notes  pursuant to the
Indenture in the May  Offering.  The proceeds  were used as described in "Use of
Proceeds."

                                    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  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

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 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."



                                      -46-
<PAGE>
         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 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.

<PAGE>
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%.

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



                                      -48-
<PAGE>
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
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



                                      -49-
<PAGE>
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 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.



                                      -50-


<PAGE>
         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.

         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



                                      -51-
<PAGE>
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.

         GST Pacwest Telecom Hawaii Incorporated 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



                                      -52-
<PAGE>
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. 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  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



                                      -53-
<PAGE>
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.

EMPLOYEES

         As of July  31,  1997,  the  Company  and its  subsidiaries  had  1,074
full-time  employees.  None  of  such  employees  is  covered  by  a  collective
bargaining agreement.  The Company considers its relationship with its employees
to be satisfactory.

FACILITIES

         The Company owns a building comprising 60,000 square feet that contains
its principal  executive offices located at 4317 N.E.  Thurston Way,  Vancouver,
Washington 98662. Its telephone number at that address is (360) 254-4700.

         The Company recently purchased property comprising approximately 13,000
square  feet in  Molokai,  Hawaii for a total  purchase  price of  approximately
$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 March 24, 2007.  The Company's  current  aggregate  annual
rental expense is approximately $4.0 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 complaint further alleges 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 seeks  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.  An  Answer  and  Counterclaim  has been  filed in  which  NACT  denies
infringement of the Aerotel Patent and seeks judgment that the Aerotel Patent is
invalid and  unenforceable  and that Aerotel has misused its patent in violation
of antitrust  laws.  NACT also denies that it has committed  defamation,  unfair
competition  and tortious  interference  with  prospective  business  relations.
Pretrial  discovery has commenced and is scheduled to be completed by the end of
1997. On May 3, 1996, NACT served its motion for summary judgment. The Court has
not yet ruled on NACT's motion.  On January 24, 1997,  Aerotel served its motion
to



                                      -54-
<PAGE>
amend its  complaint  to  include as  defendants  GST and GST USA as well as two
former  employees of NACT. The case is still in the discovery phase. The case is
not expected to be tried until late 1997 at the earliest.  NACT's patent counsel
believes  that NACT has valid  defenses to the Aerotel  claims.  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 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  agrees 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 permits GST Tucson
to modify its current route map and 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



                                      -55-
<PAGE>
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  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.

                          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,  which describes certain provisions of the Indenture and the
Notes,  does not purport to be complete  and is subject to, and is  qualified in
its  entirety  by  reference  to, the  Indenture  and the Notes,  including  the
definitions  therein of terms not  defined  herein  and those  terms made a part
thereof by the Trust  Indenture Act.  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



                                      -57-
<PAGE>
"Pledge  Agreement")  dated as of the  Closing  Date from GST  Funding to United
States Trust  Company of New 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.

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

<PAGE>
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.

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, GST USA's  subsidiaries  other than GST Funding
had $114.4 million of liabilities (excluding intercompany  payables),  including
$90.5  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

"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."

be pari  passu  with,  or  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

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  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,



                                      -76-
<PAGE>
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.

         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



                                      -77-
<PAGE>
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

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

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

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



                                      -78-
<PAGE>
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 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.



                                      -79-
<PAGE>
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
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



                                      -80-
<PAGE>
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, 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



                                      -81-
<PAGE>
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 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  for United States holders of Notes to effect service of
process  within the  United  States  upon GST or 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.  GST
believes that there is substantial doubt 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.  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



                                      -83-
<PAGE>
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.

         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



                                      -84-
<PAGE>
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.

         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 does not purport to be complete and is subject to,
and  qualified  in its  entirety by  reference  to, all the  provisions  of such
documents,  including the  definitions of certain terms therein.  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.



                                      -86-
<PAGE>
         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
(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 and (iv) pursuant to an amendment to the Tomen Master Agreement
and the Tomen Stock  Purchase  Agreement  for an aggregate  of $800,000,  74,074
Common Shares and 46,155 Warrants to purchase Common Shares at an exercise price
of $12.96 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.

         PROPOSED PROJECTS

         Tomen has agreed in principle to provide the Company with $41.0 million
of debt financing for the upgrade of its Hawaii network and the  construction of
the  Hawaiian  inter-island  network.  The Company  expects that GST Hawaii will
enter into a credit agreement with Tomen containing  substantially similar terms
as the Credit  Agreement,  except that the loan will  amortize  in 22  quarterly
installments  beginning  two and one half years after the closing  date for such
agreement.

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



                                      -87-
<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



                                      -88-
<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



                                      -89-
<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, 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.

<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



                                      -92-
<PAGE>
new rules 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.

         An exchange of Notes  pursuant to the Exchange Offer and the assumption
of the Notes by GST USA should not be considered a taxable event.

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  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



                                      -93-
<PAGE>
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).



                                      -94-
<PAGE>
         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



                                      -95-

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
upon for the Company by Olshan  Grundman  Frome & Rosenzweig  LLP, New York, New
York,  counsel  to the  Company.  Stephen  Irwin,  Esq.  is of counsel to Olshan
Grundman  Frome & Rosenzweig  LLP.  Mr.  Irwin,  Vice  Chairman of the Board and

                                  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)

       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
       from  March 5, 1997  (date of  inception)  ended  June 30,  1997,  was an
       increase of $1,632.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

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

         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 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).


                                      II-1
<PAGE>
              (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) 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.

         (2) That every  prospectus  (i) that is filed pursuant to paragraph (1)
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



                                      II-3
<PAGE>
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 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.

                  FOURTH:  The  aggregate  number of  shares of stock  which the
Corporation  shall have  authority to issue is One  Thousand  (1,000) with a par

                  FIFTH: The name and mailing address of the Incorporator is:

                                    Adam K. Levine

<PAGE>

                          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

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,


                                       -2-

<PAGE>

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  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


                                       -3-

<PAGE>

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.

                  EIGHTH:  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 EIGHTH.

                  IN WITNESS  WHEREOF,  I have hereunto set my hand this 5th day
of March, 1997.

                                  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 two or more directors or the Chairman

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

law or the Certificate of Incorporation,  the holders of record of a majority of
the shares of stock  entitled to be voted  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

meeting as originally called.

                  SECTION  1.5.  CHAIRMAN  AND  SECRETARY  AT  MEETING.  At each
meeting of stockholders  the Chairman of the Board, or in his absence the person

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,

                  SECTION 1.7. ADJOURNED MEETINGS. A meeting of stockholders may
be adjourned  to another  time or place as provided in Section  1.4.  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 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


                                       -3-


<PAGE>

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.

                                   ARTICLE II

                                    DIRECTORS

                  SECTION   2.1.   NUMBER;   TERM  OF  OFFICE;   QUALIFICATIONS;
VACANCIES.  The  number  of the  directors  constituting  the  entire  Board  of
Directors  shall be the number,  not less than two nor more than 15,  fixed from
time  to  time  by a  majority  of the  total  number  of  directors  which  the
Corporation  would have,  prior to any  increase or  decrease,  if there were no
vacancies,  provided,  however,  that no decrease  shall  shorten the term of an
incumbent  director.  Until  otherwise  fixed by the  directors,  the  number of
directors  constituting  the entire  Board  shall be three.  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

Directors 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
removed, with or without cause, by the vote or written consent of the holders of
a majority of the shares entitled to vote at an election of directors.

                  SECTION  2.4.  REGULAR AND ANNUAL  MEETINGS;  NOTICE.  Regular
meetings of the Board of Directors shall be held at such

Directors  may  from  time to time  prescribe.  No  notice  need be given of any
regular meeting,  and a notice, 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,  the

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 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  seven 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  furnished  the  Corporation  for that
purpose,  or (b) by delivery of the notice  similarly  addressed for dispatch by
telegraph,  cable or radio or by  delivery  of the  notice  by  telephone  or in
person, in each case at least 24 hours before the time fixed for the meeting.

                  SECTION 2.6. PRESIDING OFFICER AND SECRETARY AT MEETINGS. Each
meeting of the Board of Directors  shall be presided over by the Chairman of the
Board or in his  absence by such  member of the Board of  Directors  as shall be
chosen at the meeting. The Secretary,  or in his absence an Assistant Secretary,
shall act as  secretary  of the  meeting,  or if no such  officer is present,  a
secretary of the meeting shall be designated  by the person  presiding  over the
meeting.

                  SECTION 2.7. QUORUM. Three directors shall constitute a quorum
for the  transaction  of business,  but in the absence of a quorum a majority of
those  present  (or if only one be  present,  then  that  one) may  adjourn  the
meeting,  without notice other than announcement at the meeting, until such time
as a quorum is present.  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.

<PAGE>

                  SECTION  2.9.  ACTION  WITHOUT   MEETING.   Unless   otherwise
restricted by the Certificate of Incorporation, any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof
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.  COMMITTEES OF THE BOARD. The Board of Directors
may, by resolution passed by the whole Board of Directors, designate 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
the powers and  authority  of the Board of Directors  in the  management  of the
business and affairs of the  Corporation,  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   stockholders  a
dissolution of the Corporation or a revocation of a dissolution, or amending the
By-Laws; and unless the resolution shall expressly so provide, no such committee
shall have the power or  authority  to declare a dividend  or to  authorize  the
issuance  of  stock.  In  the  absence  or  disqualification  of a  member  of a
committee,  the  member  or  members  thereof  present  at any  meeting  and not
disqualified  from voting,  whether or not he or they  constitute a quorum,  may
unanimously  appoint  another  member  of the Board of  Directors  to act at the
meeting  in the  place of any such  absent  or  disqualified  member.  Each such
committee  shall  have such name as may be  determined  from time to time by the
Board of Directors.

                  SECTION  2.11.  COMPENSATION.  No director  shall  receive any
stated  salary for his services as a director or as a member of a committee  but
shall  receive such sum, if any, as may from time to time be fixed by the action
of a majority of the stockholders.

Corporation  shall be a Chairman  of the Board,  a  President,  one or more Vice

Controllers and such other officers as it may from time to time  determine.  Two
or more offices may be held by the same person.

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.

                  SECTION 3.4. REMOVAL.  Any officer may be removed at any time,

office of the Corporation may be filled by the Board of Directors.

                                  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
a majority  vote of the  directors  who are not parties to such action,  suit or
proceeding,  even  though  less  than a  quorum,  or (2) if  there  are no  such
directors,  or if such directors so direct,  by  independent  legal counsel in a
written opinion, or (3) 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.

         DELIVERY OF THIS LETTER OF  TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET
FORTH ABOVE OR TRANSMISSION OF  INSTRUCTIONS  VIA A FACSIMILE  TRANSMISSION TO A
NUMBER OTHER THAN AS SET FORTH ABOVE WILL NOT CONSTITUTE A VALID DELIVERY.

         The undersigned acknowledges receipt of the Prospectus dated _________,
1997 (the "Prospectus") of GST Equipment  Funding,  Inc. ("GST Funding") and GST
Telecommunications, Inc. ("GST") which, together with this Letter of Transmittal
(the "Letter of  Transmittal"),  constitute  GST Funding's  offer (the "Exchange
Offer") to exchange $1,000 in principal amount of a new series of 13 1/4% Senior
Secured Exchange Notes Due 2007 (the "New Notes") of GST Funding,  which,  under
certain  circumstances,  may be  guaranteed  by GST for each $1,000 in principal
amount of outstanding 13 1/4% Senior Secured Notes Due 2007 (the "Old Notes") of
GST Funding,  which, under certain circumstances,  may be guaranteed by GST. The
terms of the New Notes are  identical in all  material  respects to the terms of
the Old Notes for which they may be exchanged  pursuant to the  Exchange  Offer,
except that the offer and sale of the New Notes will have been registered  under
the Securities Act of 1933, as amended (the "Securities  Act"), and,  therefore,
the New Notes will not bear legends restricting the transfer thereof.

Letter of  Transmittal  to indicate the action the  undersigned  desires to take
with respect to the Exchange Offer.

         PLEASE  READ  THE  ENTIRE  LETTER  OF  TRANSMITTAL  AND THE  PROSPECTUS

               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

         Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to GST Funding the  above-described  principal amount
of Old Notes. Subject to, and effective upon, the acceptance for exchange of the
Old Notes tendered  herewith,  the  undersigned  hereby  exchanges,  assigns and
transfers to, or upon the order of, GST Funding right, title and interest in and
to such Old Notes. The undersigned hereby  irrevocably  constitutes and appoints
the  Exchange  Agent as the true and lawful  agent and  attorney-in-fact  of the
undersigned  (with full  knowledge that said Exchange Agent acts as the agent of
the undersigned in connection with the Exchange Offer) to cause the Old Notes to
be assigned,  transferred and exchanged. The undersigned 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 undersigned also warrants that it will, upon request,
execute and deliver any additional documents deemed by the Exchange Agent or GST
Funding to be necessary or desirable to complete the  exchange,  assignment  and
transfer of tendered Old Notes.

         The Exchange Offer is subject to certain conditions as set forth in the
Prospectus  under the caption  "Exchange  Offer --  Conditions  to the  Exchange
Offer." The undersigned  recognizes that as a result of these conditions  (which
may be waived,  in whole or in part,  by GST Funding) as more  particularly  set
forth in the Prospectus,  GST Funding may not be required to exchange any of the
Old Notes tendered  hereby and, in such event,  the Old Notes not exchanged will
be returned to the  undersigned  at the address shown below the signature of the
undersigned.

         By  tendering,  each Holder of Old Notes  represents to GST Funding and
GST that (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 a  distribution  of the New
Notes and (iv) neither the Holder nor any such other person is an "affiliate" of
GST Funding or GST within the meaning of Rule 405 under the  Securities  Act or,
if such  Holder is such an  "affiliate,"  that such  Holder will comply with the
registration and prospectus  delivery  requirements of the Securities Act to the
extent applicable. If the tendering Holder is a broker-dealer (whether or not it
is also an  "affiliate"  of GST  Funding or GST  within the  meaning of Rule 405
under the  Securities  Act) that will  receive  New Notes for its own account in
exchange for Old Notes, it represents that the Old Notes to be exchanged for the
New Notes were acquired by it as a result of  market-making  activities or other
trading  activities,  and acknowledges that it will deliver a prospectus meeting
the



                                       -4-
<PAGE>
requirements  of the  Securities  Act in connection  with any resale of such New
Notes.  By  acknowledging  that it will  deliver and by  delivering a prospectus
meeting the  requirements of the Securities Act in connection with any resale of
such  New  Notes,  the  undersigned  is  not  deemed  to  admit  that  it  is an
"underwriter" within the meaning of the Securities Act.

         All authority  herein conferred or agreed to be conferred shall survive
the death,  bankruptcy or incapacity of the undersigned and every  obligation of
the   undersigned   hereunder   shall  be  binding  upon  the  heirs,   personal
representatives,  successors and assigns of the undersigned.  Tendered Old Notes
may be  withdrawn  at any time  prior to 5:00  p.m.,  New York  City time on the
business day prior to the Expiration Date.

         Certificates  for all New Notes  delivered in exchange for tendered Old
Notes and any Old  Notes  delivered  herewith  but not  exchanged,  in each case
registered in the name of the undersigned, shall be delivered to the undersigned
at the address shown below the signature of the undersigned.

Prospectus);  (ii) on or prior to the  Expiration  Date, the Exchange Agent must
have  received from such  Eligible  Institution a letter,  telegram or facsimile
transmission  setting  forth the name and address of the tendering  Holder,  the
names in which such Old Notes are registered,  and, if possible, the certificate

well as this  Letter of  Transmittal  and all other  documents  required by this
Letter of  Transmittal  must be  received by the  Exchange  Agent  within  three

the Old Notes for exchange.

         2. PARTIAL TENDERS; WITHDRAWALS.  Tenders of Old Notes will be accepted
in denominations  of $1,000  principal  amount and integral  multiples in excess
thereof.  If less than the entire  principal  amount of Old Notes evidenced by a
submitted  certificate  is  tendered,  the  tendering  Holder  must  fill in the
principal  amount tendered in the box entitled  "Principal  Amount  Tendered." A
newly issued certificate for the principal amount of Old Notes submitted but not
tendered will be sent to such Holder as soon as practicable after the Expiration

         If this  Letter of  Transmittal  is signed by a person  other  than the

instruments  of  transfer  or  exchange  are  signed  by  trustees,   executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others

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

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
person) will be payable by the tendering  Holder.  If  satisfactory  evidence of
payment of such taxes or exemption  therefrom  is not  submitted  herewith,  the
amount of such transfer taxes will be billed directly to such tendering Holder.

         PLEASE NOTE THAT THE EXCHANGE  OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK

                  The Exchange Offer is not conditioned  upon any minimum number
of Old Notes being tendered.

                  We are the  holder of record of Old Notes  held by us for your
account.  A tender of such Old Notes can be made only by us as the record holder
and pursuant to your instructions. The Letter of Transmittal is furnished to you
for your  information only and cannot be used by you to tender Old Notes held by
us for your account.

                  We request  instructions  as to whether you wish to tender any
or all of the Old Notes held by us for your  account  pursuant  to the terms and
conditions of the Exchange  Offer.  We also request that you confirm that we may

person receiving such New Notes, whether or not such person is such holder, (ii)
neither the holder of the Old Notes nor any such other person has an arrangement
or understanding  with any person to participate in the distribution of such New

is also an  "affiliate")  that will  receive  New Notes for its own  account  in
exchange for Old Notes, we will represent on behalf of such  broker-dealer  that
the Old Notes to be exchanged  for the New Notes were acquired by it as a result
of  market-making  activities or other trading  activities,  and  acknowledge on
behalf of such  broker-dealer  that it will  deliver a  prospectus  meeting  the
requirements  of the  Securities  Act in connection  with any resale of such New
