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

         The following management's discussion and analysis of financial
condition and results of operations contains forward looking statements that
involve risks and uncertainties. The Company's actual results could differ
materially from those anticipated in these forward looking statements as a
result of certain factors discussed herein.

OVERVIEW

         GST Telecommunications, Inc. (the "Company") provides a broad range of
integrated telecommunications products and services, primarily to customers
located in the western continental United States and Hawaii. Since inception as
a facilities-based competitive access provider ("CAP"), the Company has
constructed and operated state- of-the-art, digital telecommunications networks
that provide an alternative to incumbent local exchange carriers. The Company
has expanded beyond the scope of traditional CAP operations into competitive
local exchange carrier ("CLEC") services and currently provides, through its
established sales channels, a range of enhanced telecommunications services that
include long distance, internet access and data services. In addition, the
Company provides switched access and recently began to provide local dial tone
services to complement its existing telecommunications service offerings. The
Company also provides advanced telecommunications switching platforms with
integrated applications software and network telemanagement capabilities through
its wholly owned subsidiary, NACT Telecommunications, Inc. ("NACT").

         The Company's fiber optic networks currently serve 18 cities in
Arizona, California, Hawaii, New Mexico and Washington and its digital microwave
network serves four of the Hawaiian Islands. In addition, the Company has 20
networks under construction and two networks in development, thereby expanding
its regional footprint to include Idaho, Oregon, Texas and Utah.

         The Telecommunications Act of 1996 and several 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. Management believes that the
Company has an opportunity to leverage its network infrastructure and service
capabilities to expand the Company's addressable market and to improve its
opportunity to participate, on a regional basis, in both the local and long
distance telecommunications markets in the United States. In order to capitalize
on these opportunities, the Company has accelerated the development and
construction of additional networks within its region. In addition, to
facilitate the provision of local services, the Company has deployed nine high
capacity digital switches, one of which is operational and the balance of which
are expected to be operational in the first half of 1997. The Company intends to
deploy an additional five such switches in the first half of 1997, all of which
are expected to be operational by the third quarter of 1997.

RESULTS OF OPERATIONS

         REVENUES. Total revenues for the three months ended December 31, 1996
increased $16.7 million to $23.2 million from $6.5 million for the three months
ended December 31, 1995. Telecommunications services revenues for the three
months ended December 31, 1996 increased $13.9 million to $18.4 million from
$4.5 million for the comparable period in the previous year. The increase in
telecommunications services revenues resulted from the inclusion of revenues
from strategic acquisitions, including Call America Business Communications
Corporation and affiliated companies and TotalNet Communications, Inc., 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 months ended December 31, 1996 increased $2.8
million to $4.8 million from $2.0 million for the three months ended December
31, 1995. The increase in telecommunication products revenues resulted from
increased unit sales of NACT's STX switch.

         OPERATING EXPENSES. Total operating expenses for the three months ended
December 31, 1996 increased $28.7 million to $41.2 million from $12.5 million
for the three months ended December 31, 1995. Network expenses, which include
direct local and long distance circuit costs, increased $11.5 million to $15.7
million for the three months ended December 31, 1996 from $4.2 million for the
comparable period in the previous year. As a percentage of telecommunications
services revenues, network expenses decreased from 93.2% for the three months
ended December 31, 1995 to 85.3% for the three months ended December 31, 1996.
Facilities administration and maintenance expenses for the three months ended
December 31, 1996 increased $2.0 million to $3.3 million from $1.3 million for
the three months ended December 31, 1995. The increase relates to additional
personnel and facility costs associated with network expansion. As a percentage
of telecommunication services revenues, facilities administration and
maintenance expense decreased from 29.6% for the three months ended December 31,
1995 to 18.0% for the three months ended December 31, 1996. The decrease results
from the expansion of the Company's customer base over the past year.

         Cost of product revenues at NACT for the three months ended December
31, 1996 increased $1 million to $1.8 million from $.8 million for the three
months ended December 31, 1995. As a percentage of telecommunications products
revenues, cost of product revenues decreased from 40.6% to 38.1% for the same
periods. The decrease results from increased unit sales and the resultant
economies of scale. Research and development costs at NACT increased from $283
for the three months ended December 31, 1995 to $410 for the three months ended
December 31, 1996. The increase is primarily due to the addition of personnel to
enhance the current switch product line and to facilitate the development of new
switching products.

         Selling, general and administrative expenses for the three months ended
December 31, 1996 increased $10.7 million to $15.2 million from $4.5 million for
the three months ended December 31, 1995. The increase is primarily due to the
expansion of the Company's CLEC and enhanced services operations and the
acquisition of three long distance companies, an Internet service provider and a
provider of shared tenant services during the fiscal year ended September 30,
1996 ("Fiscal 1996"). The implementation of the Company's integrated services
strategy has resulted in additional marketing, management information and sales
staff dedicated to network expansion and increased service offerings.

         Depreciation and amortization for the three months ended December 31,
1996 increased $3.4 million to $4.7 million from $1.3 million for the comparable
period in the previous year. The increase is attributable to newly-constructed
networks becoming operational and to the amortization of intangible assets
related to the Company's Fiscal 1996 acquisitions. The Company expects that
depreciation will continue to increase as it expands its networks and provides
switched services.

         OTHER EXPENSES. Other expenses for the three months ended December 31,
1996 increased $3.0 million to $4.7 million from $1.7 million for the three
months ended December 31, 1995. The increase is principally the result of
additional interest expense associated with the December 1995 debt offering. The
increase was partially offset by the interest income resulting from the
investment of the proceeds of such offering.

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. The Company has financed, and expects to continue to
finance, its capital expenditures, acquisitions and working capital requirements
primarily through the sale of equity and debt securities.

         Net cash provided by financing activities from borrowings and equity
issuances to fund capital expenditures, acquisitions and operating losses was
$34.7 million and $173.0 million for the three month periods ended December


                                      -10-
<PAGE>

31, 1996 and 1995, respectively. The Company's net cash used in operating and
investment activities was $82.7 million and $14.2 million for the three month
periods ended December 31, 1996 and 1995, respectively.

         Capital expenditures for the three months ended December 31, 1996 and
1995 were $58.0 million and $8.1 million, respectively. The Company estimates
capital expenditures of in excess of $350 million for the 1997 and 1998 fiscal
years. The actual amount and timing of such expenditures will be dependent upon
a number of factors, including the availability of equity and debt financing,
customer demand, the ability to conclude interconnection agreements and the
regulatory environment. These expenditures will be utilized for the expansion,
development and construction of the Company's networks, the acquisition and
deployment of switches and related equipment to facilitate the offering of
advanced telecommunications services and internal management systems. Continued
significant capital expenditures are expected to be made thereafter. In
addition, the Company expects to continue to incur increasing 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 the nature of future expansion and acquisition
opportunities, economic conditions, competition, regulatory developments and the
availability of capital.

         The Company completed a $180 million debt offering in December 1995,
consisting of $160 million in senior discount notes and $20 million in
convertible senior subordinated discount notes (collectively, the "1995 Notes").
The net proceeds from the issuance of the 1995 Notes, $171.3 million, are being
used to fund network development, capital expenditures and working capital
requirements. The indentures governing the 1995 Notes include restrictive
covenants which, among other items, limit or restrict additional indebtedness
incurred by the Company, investment in certain subsidiaries and the payment of
dividends.

         In October 1994, the Company and Tomen entered into agreements (the
"Tomen Facility") pursuant to which Tomen agreed to make available up to a total
of $100 million of financing, on a project-by-project basis, for the
construction and development of network projects. Tomen has a right of first
refusal to finance each network project up to the limit of the facility. To
date, Tomen has provided, or agreed to provide, $34.5 million in debt financing
under the Tomen Facility for the Company's network projects in Southern
California, Tucson and Albuquerque.] Furthermore, Tomen has purchased 1,324,074
common shares of the Company, without par value (the "Common Shares"), and holds
warrants to purchase 296,155 additional Common Shares. In November 1996 Tomen
agreed in principle to provide the Company with $41 million of additional
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 75,000 additional
Common Shares.

         In October 1996 the Company completed a private placement to non-U.S.
investors of two million special warrants (the "Special Warrants"). Each Special
Warrant is exercisable for one Common Share and one-half of an underlying
warrant. Each full 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. The Special Warrants become exercisable by the holders for no
additional consideration upon the receipt of approval of the Canadian prospectus
(the "Canadian Prospectus") from the securities commission of each of the
Canadian provinces where the Special Warrants were sold, but in any event, no
later than September 22, 1997. In the event that the requisite regulatory
approvals for the Canadian Prospectus are not received by the Company by
February 19, 1997, then each Special Warrant will become exercisable for 1.1
Common Shares and one-half of one underlying warrant. The Company received $9.7
million in net proceeds in October 1996 and the remaining $11.1 million in net
proceeds in January 1997.

         In September 1996, the Company entered into a loan agreement with
Siemens Stromberg-Carlson ("Siemens") 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 an agreement with Northern Telecom Finance Company ("NTFC"), which provides
for $50 million of equipment


                                      -11-
<PAGE>

financing to finance the purchase of equipment and products from Northern
Telecom, Inc. As of December 31, 1996, the Company has borrowed $26 million
pursuant to the NTFC agreement.

         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 December 31, 1996, the Company had cash, cash equivalents,
restricted cash and investments of $24.5 million, compared to $82.5 million at
September 30, 1996. Management believes that the cash on hand, the proceeds from
the Special Warrants offering, the expected proceeds of approximately $10
million from the public offering of NACT's common stock whereby the Company and
NACT will sell one million and two million shares respectively, of NACT's common
stock, borrowings expected to be available under the Tomen Facility, the NTFC
agreement and the Siemens agreement and currently contemplated offerings of the
Company's debt and equity securities will provide sufficient funds for the
Company to expand its business as presently planned and to fund its operating
expenses through December 31, 1997. Thereafter, the Company expects to acquire
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, the currently contemplated offerings of debt and equity
securities 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 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 or expansion plans, and could have a 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.

         Although the Company's liquidity substantially improved as a result of
the 1995 Notes offering because the 1995 Notes do not require the payment of
cash interest prior to June 2001 and the 1995 Notes do not require payment of
principal until maturity in 2005, a portion of the indebtedness under the Tomen
Facility will, and a portion of the equipment financing may, 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 may be insufficient to repay the 1995 Notes in full at maturity and
that such notes may need to be refinanced. 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 or equipment financing.
Because the Company does not currently have a revolving credit facility, if a
shortfall occurs, alternative financing would be necessary in order for the
Company to meet its liquidity requirements and there can be no assurance that
such financing would be available. In such event, the Company could face
substantial liquidity problems. The ability of the Company to meets its
obligations and 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.

                                                              As amended through
                                                                January 14, 1997

                          GST TELECOMMUNICATIONS, INC.

                             1996 STOCK OPTION PLAN

         1.       PURPOSE OF THE PLAN.

                  This 1996 Stock  Option  Plan (the  "Plan") is  intended as an
incentive,  to retain in the employ of and as  consultants  and  advisors to GST
TELECOMMUNICATIONS,  INC., a Canadian  corporation  with its principal office at
4317 N.E.  Thurston Way,  Vancouver,  Washington  98662 (the  "Company") and any
Subsidiary  of the Company,  within the meaning of Section  425(f) of the United
States  Internal  Revenue  Code of 1986,  as amended  (the  "Code"),  persons of
training, experience and ability, to attract new employees,  directors, advisors
and consultants whose services are considered  valuable,  to encourage the sense
of  proprietorship  and to stimulate the active  interest of such persons in the
development and financial success of the Company and its Subsidiaries.

                  It is further  intended that certain options granted  pursuant
to the Plan shall  constitute  incentive  stock  options  within the  meaning of
Section 422 of the Code (the  "Incentive  Options")  while certain other options
granted  pursuant  to  the  Plan  shall  be  nonqualified   stock  options  (the
"Nonqualified   Options").   Incentive  Options  and  Nonqualified  Options  are
hereinafter referred to collectively as "Options."

                  The Company  intends  that the Plan meet the  requirements  of
Rule 16b-3 ("Rule 16b-3") promulgated under the Securities Exchange Act of 1934,
as amended (the "Exchange  Act") and that  transactions of the type specified in
subparagraphs  (c) to (f)  inclusive of Rule 16b-3 by officers and  directors of
the Company  pursuant to the Plan will be exempt from the  operation  of Section
16(b) of the Exchange Act. In all cases, the terms,  provisions,  conditions and
limitations of the Plan shall be construed and  interpreted  consistent with the
Company's intent as stated in this Section 1.

         2.       ADMINISTRATION OF THE PLAN.

                  The Board of  Directors  of the Company  (the  "Board")  shall
appoint and maintain as administrator of the Plan a Committee (the  "Committee")
consisting  of two or more  Non-Employee  Directors  (as such term is defined in
Rule  16b-3),  which shall serve at the  pleasure of the Board.  The  Committee,
subject to  Sections 3 and 5 hereof,  shall  have full  power and  authority  to
designate  recipients  of Options,  to  determine  the terms and  conditions  of
respective
<PAGE>

Option  agreements (which need not be identical) and to interpret the provisions
and  supervise the  administration  of the Plan.  The  Committee  shall have the
authority, without limitation, to designate which Options granted under the Plan
shall be  Incentive  Options and which  shall be  Nonqualified  Options.  To the
extent any Option does not qualify as an Incentive Option, it shall constitute a
separate Nonqualified Option.

                  Subject to the  provisions of the Plan,  the  Committee  shall
interpret the Plan and all Options granted under the Plan, shall make such rules
as it deems necessary for the proper  administration of the Plan, shall make all
other  determinations  necessary or advisable for the administration of the Plan
and  shall  correct  any  defects  or  supply  any  omission  or  reconcile  any
inconsistency in the Plan or in any Options granted under the Plan in the manner
and to the extent that the  Committee  deems  desirable to carry into effect the
Plan or any Options.  The act or  determination  of a majority of the  Committee
shall be the act or  determination  of the Committee and any decision reduced to
writing  and  signed  by all of the  members  of the  Committee  shall  be fully
effective as if it had been made by a majority at a meeting  duly held.  Subject
to the  provisions of the Plan,  any action taken or  determination  made by the
Committee  pursuant  to  this  and the  other  Sections  of the  Plan  shall  be
conclusive on all parties.

                  In the event that for any reason  the  Committee  is unable to
act or if the  Committee  at the time of any grant,  award or other  acquisition
under the Plan of Options or Stock does not consist of two or more  Non-Employee
Directors,  then any such grant,  award or other  acquisition may be approved or
ratified in any other manner contemplated by subparagraph (d) of Rule 16b-3.

         3.       DESIGNATION OF OPTIONEES.

                  The  persons  eligible  for   participation  in  the  Plan  as
recipients of Options (the "Optionees")  shall include  employees,  officers and
directors of, and  consultants  and advisors to, the Company or any  Subsidiary;
provided that Incentive  Options may only be granted to employees of the Company
and the Subsidiaries.  In selecting Optionees,  and in determining the number of
shares to be covered by each Option  granted to  Optionees,  the  Committee  may
consider  the  office  or  position  held  by the  Optionee  or  the  Optionee's
relationship to the Company,  the Optionee's  degree of  responsibility  for and
contribution  to the growth and  success of the Company or any  Subsidiary,  the
Optionee's length of service,  age, promotions,  potential and any other factors
that the  Committee may consider  relevant.  An Optionee who has been granted an
Option  hereunder  may be  granted  an  additional  Option  or  Options,  if the
Committee shall so determine.

         4.       STOCK RESERVED FOR THE PLAN.

                  Subject to adjustment as provided in Section 7 hereof, a total
of 400,000 shares of the Company's  Common Shares (the "Stock") shall be subject
to the Plan.  The shares of Stock  subject to the Plan shall consist of unissued
shares or previously  issued shares held by any  Subsidiary of the Company,  and
such amount of shares of Stock shall be and is hereby reserved for such purpose.
Any of such  shares of Stock that may remain  unsold and that are not subject to
outstanding  Options at the  termination  of the Plan shall cease to be reserved
for the  purposes  of the Plan,  but until  termination  of the Plan the Company
shall at all times  reserve a  sufficient  number of shares of Stock to meet the
requirements of the Plan.  Should any Option expire or be cancelled prior to its
exercise  in full or should the number of shares of Stock to be  delivered  upon
the exercise in full of an Option be reduced for any reason, the shares of Stock
theretofore  subject to such Option may be subject to future  Options  under the
Plan.

         5.       TERMS AND CONDITIONS OF OPTIONS.

                  Options  granted  under  the  Plan  shall  be  subject  to the
following conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of the Plan, as the Committee shall deem desirable:

                           (a) OPTION PRICE. The purchase price of each share of
Stock purchasable under an Incentive Option shall be determined by the Committee
at the time of grant,  but shall not be less than 100% of the Fair Market  Value
(as  defined  below) of such share of Stock on the date the  Option is  granted;
PROVIDED,  HOWEVER,  that with  respect  to an  Optionee  who,  at the time such
Incentive  Option is granted,  owns (within the meaning of Section 424(d) of the
Code) more than 10% of the total  combined  voting power of all classes of stock
of the Company or of any Subsidiary, the purchase price per share of Stock shall
be at least  110% of the Fair  Market  Value  per  share of Stock on the date of
grant.  The  purchase  price  of  each  share  of  Stock   purchasable  under  a
Nonqualified  Option shall not be less than 80% of the Fair Market Value of such
share of Stock on the date the Option is  granted;  PROVIDED,  HOWEVER,  that an
Optionee who is a Canadian  taxpayer may require  that any  Nonqualified  Option
granted to him provide for the purchase of shares of Stock upon exercise thereof
at a price  equal to the Fair  Market  Value  per  share of Stock on the date of
grant.  The  exercise  price for each Option shall be subject to  adjustment  as
provided  in Section 7 below.  Fair  Market  Value  means the  closing  price of
publicly  traded  shares  of Stock on the  principal  United  States  securities
exchange  on which  shares of Stock are  listed  (if the  shares of Stock are so
listed),  or on the NASDAQ  Stock  Market (if the shares of Stock are  regularly
quoted on the NASDAQ Stock  Market),  or, if not so listed or regularly  quoted,
the mean between the closing bid and asked prices of publicly  traded  shares of
Stock in the


                                       -3-
<PAGE>

over-the-counter  market,  or,  if  such  bid  and  asked  prices  shall  not be
available,  as reported by any nationally  recognized quotation service selected
by the Company,  or as determined by the Committee in a manner  consistent  with
the  provisions  of the Code.  Anything  in this  Section  5(a) to the  contrary
notwithstanding,  in no event  shall the  purchase  price of a share of Stock be
less than the minimum price  permitted  under rules and policies of the American
Stock Exchange and the Vancouver Stock Exchange.

                           (b) OPTION  TERM.  The term of each  Option  shall be
fixed by the Committee,  but no Option shall be exercisable more than five years
after the date such Option is granted.

                           (c)  EXERCISABILITY.  Subject to Section 5(j) hereof,
Options shall be exercisable at such time or times and subject to such terms and
conditions as shall be determined by the Committee at the time of grant.

                           (d) METHOD OF  EXERCISE.  Options to the extent  then
exercisable  may be  exercised in whole or in part at any time during the option
period, by giving written notice to the Company  specifying the number of shares
of Stock to be purchased,  accompanied by payment in full of the purchase price,
in  cash,  by  check  or  such  other  instrument  as may be  acceptable  to the
Committee. As determined by the Committee,  in its sole discretion,  at or after
grant, payment in full or in part may also be made in the form of Stock owned by
the  Optionee  (based on the Fair  Market  Value of the Stock on the trading day
before the Option is  exercised).  An Optionee shall have the right to dividends
and other rights of a stockholder with respect to shares of Stock purchased upon
exercise  of an  Option  after (i) the  Optionee  has  given  written  notice of
exercise and has paid in full for such shares and (ii) becomes a stockholder  of
record with respect thereto.

                           (e)  NON-TRANSFERABILITY OF OPTIONS.  Options are not
transferable  and may be exercised solely by the Optionee during his lifetime or
after his death by the person or persons  entitled thereto under his will or the
laws of descent and  distribution.  Any attempt to transfer,  assign,  pledge or
otherwise dispose of, or to subject to execution, attachment or similar process,
any Option  contrary to the provisions  hereof shall be void and ineffective and
shall give no right to the purported transferee.

                           (f) TERMINATION BY DEATH. Unless otherwise determined
by the Committee at grant,  if any Optionee's  employment with or service to the
Company  or any  Subsidiary  terminates  by  reason  of death,  the  Option  may
thereafter be exercised,  to the extent then exercisable (or on such accelerated
basis  as the  Committee  shall  determine  at or  after  grant),  by the  legal
representative of the estate or by the legatee of the Optionee under the will of
the Optionee, for a period of one year after the


                                       -4-
<PAGE>

date of such death or until the  expiration of the stated term of such Option as
provided under the Plan, whichever period is shorter.

                           (g)  TERMINATION  BY  REASON  OF  DISABILITY.  Unless
otherwise  determined by the Committee at grant,  if any  Optionee's  employment
with or service to the Company or any  Subsidiary  terminates by reason of total
and permanent  disability,  any Option held by such  Optionee may  thereafter be
exercised,  to the extent it was  exercisable at the time of termination  due to
Disability (or on such accelerated  basis as the Committee shall determine at or
after  grant),  but may not be  exercised  after 30 days  after the date of such
termination  of  employment  or service or the  expiration of the stated term of
such  Option,  whichever  period is shorter;  provided,  however,  that,  if the
Optionee  dies within such 30 day period,  any  unexercised  Option held by such
Optionee  shall  thereafter  be  exercisable  to  the  extent  to  which  it was
exercisable at the time of death for a period of one year after the date of such
death or for the stated term of such Option, whichever period is shorter.

                           (h)  TERMINATION  BY  REASON  OF  RETIREMENT.  Unless
otherwise  determined by the Committee at grant,  if any  Optionee's  employment
with or service to the Company or any Subsidiary  terminates by reason of Normal
or Early  Retirement (as such terms are defined below),  any Option held by such
Optionee may  thereafter  be exercised to the extent it was  exercisable  at the
time of such  Retirement (or on such  accelerated  basis as the Committee  shall
determine at or after grant),  but may not be exercised  after 30 days after the
date of such  termination  of  employment  or service or the  expiration  of the
stated term of such  Option,  whichever  period is shorter;  provided,  however,
that, if the Optionee  dies within such 30 day period,  any  unexercised  Option
held by such Optionee shall thereafter be exercisable, to the extent to which it
was exercisable at the time of death, for a period of one year after the date of
such death or for the stated term of such Option, whichever period is shorter.

                  For purposes of this paragraph (h),  Normal  Retirement  shall
mean retirement from active  employment with the Company or any Subsidiary on or
after  the  normal  retirement  date  specified  in the  applicable  Company  or
Subsidiary  pension plan or if no such pension  plan,  age 65. Early  Retirement
shall mean retirement from active  employment with the Company or any Subsidiary
pursuant  to the  early  retirement  provisions  of the  applicable  Company  or
Subsidiary pension plan or if no such pension plan, age 55.

                           (i) OTHER TERMINATION. Unless otherwise determined by
the  Committee at grant,  if any  Optionee's  employment  with or service to the
Company or any Subsidiary terminates for any reason other than death, Disability
or Normal or Early Retirement, the Option shall thereupon terminate, except that
the portion of any


                                       -5-
<PAGE>

Option that was exercisable on the date of such termination of employment may be
exercised for the lesser of 30 days after the date of termination or the balance
of such Option's term if the  Optionee's  employment or service with the Company
or any Subsidiary is terminated by the Company or such Subsidiary  without cause
(the  determination  as to whether  termination  was for cause to be made by the
Committee).  The  transfer  of an  Optionee  from the employ of the Company to a
Subsidiary,  or vice versa,  or from one  Subsidiary  to  another,  shall not be
deemed to constitute a termination of employment for purposes of the Plan.

                           (j) LIMIT ON VALUE OF INCENTIVE OPTION. The aggregate
Fair Market Value, determined as of the date the Incentive Option is granted, of
Stock for which  Incentive  Options  are  exercisable  for the first time by any
Optionee  during any calendar year under the Plan (and/or any other stock option
plans of the Company or any Subsidiary) shall not exceed $100,000.

                           (k) TRANSFER OF INCENTIVE  OPTION  SHARES.  The stock
option agreement  evidencing any Incentive Options granted under this Plan shall
provide that if the Optionee makes a disposition,  within the meaning of Section
424(c)  of the Code and  regulations  promulgated  thereunder,  of any  share or
shares of Stock issued to him upon exercise of an Incentive Option granted under
the Plan within the two-year period  commencing on the day after the date of the
grant of such Incentive Option or within a one-year period commencing on the day
after  the date of  transfer  of the  share or  shares  to him  pursuant  to the
exercise  of  such  Incentive  Option,  he  shall,  within  10 days  after  such
disposition,  notify the Company thereof and immediately  deliver to the Company
any amount of United States federal income tax withholding required by law.

                           (l)  LIMITATION  ON OPTIONS  HELD BY ONE PERSON.  The
aggregate  number of shares of Stock  subject to options  held by any one person
shall not exceed that number of shares as equals 5% of the outstanding shares of
the Company.

         6.       TERM OF PLAN.

                  No Option  shall be granted  pursuant  to the Plan on or after
January 5, 2006, but Options theretofore granted may extend beyond that date.

         7.       CAPITAL CHANGE OF THE COMPANY.

                  In the  event of any  merger,  reorganization,  consolidation,
recapitalization,  stock  dividend,  or  other  change  in  corporate  structure
affecting  the Stock,  the  Committee  shall make an  appropriate  and equitable
adjustment in the number and kind of shares reserved for issuance under the Plan
and in the number  and option  price of shares  subject to  outstanding  Options
granted under the Plan, to the end that after such event each Optionee's


                                       -6-
<PAGE>

proportionate  interest shall be maintained as immediately before the occurrence
of such event.

         8.       PURCHASE FOR INVESTMENT.

                  Unless the  Options  and shares  covered by the Plan have been
registered  under the United  States  Securities  Act of 1933,  as amended  (the
"Securities  Act"),  or the Company has  determined  that such  registration  is
unnecessary,  each person exercising an Option under the Plan may be required by
the Company to give a representation  in writing that he is acquiring the shares
for his own  account  for  investment  and not  with a view  to,  or for sale in
connection with, the distribution of any part thereof.

         9.       TAXES.

                  The  Company  may  make  such   provisions   as  it  may  deem
appropriate,  consistent  with  applicable  law, in connection  with any Options
granted under the Plan with respect to the  withholding  of any United States or
Canadian taxes or any other tax matters.

         10.      EFFECTIVE DATE OF PLAN.

                  The Plan shall be  effective  on  January  5,  1996,  provided
however  that the Plan shall  subsequently  be approved by majority  vote of the
Company's shareholders not later than January 4, 1997.

         11.      AMENDMENT AND TERMINATION.

                  The Board may amend,  suspend,  or terminate the Plan,  except
that no  amendment  shall be made that would  impair the rights of any  Optionee
under any Option  theretofore  granted  without his consent,  and except that no
amendment shall be made which,  without the approval of the  shareholders of the
Company would:

                           (a) materially increase the number of shares that may
be issued under the Plan, except as is provided in Section 7;

                           (b) materially  increase the benefits accruing to the
Optionees under the Plan;

                           (c)  materially   modify  the   requirements   as  to
eligibility for participation in the Plan;

                           (d)  decrease  the  exercise  price  of an  Incentive
Option to less than 100% of the Fair Market Value per share of Stock on the date
of grant thereof or the exercise price of a Nonqualified Option to less than 80%
of the Fair Market Value per share of Stock on the date of grant thereof; or


                                       -7-
<PAGE>

                           (e)  extend  the  term  of  any  Option  beyond  that
provided for in Section 5(b).

                  The  Committee  may amend the terms of any Option  theretofore
granted, prospectively or retroactively,  but no such amendment shall impair the
rights of any Optionee  without his consent.  The Committee may also  substitute
new Options for previously  granted  Options,  including  options  granted under
other plans applicable to the participant and previously  granted Options having
higher option prices, upon such terms as the Committee may deem appropriate.

         12.      GOVERNMENT REGULATIONS.

                  The Plan, and the grant and exercise of Options hereunder, and
the  obligation  of the Company to sell and deliver  shares under such  Options,
shall be subject to all  applicable  laws,  rules and  regulations,  and to such
approvals  by  any  governmental   agencies  or  national  securities  exchanges
(including the American Stock Exchange and Vancouver  Stock  Exchange) as may be
required.

         13.      GENERAL PROVISIONS.

                           (a)  CERTIFICATES.  All  certificates  for  shares of
Stock delivered under the Plan shall be subject to such stop transfer orders and
other  restrictions  as the  Committee  may  deem  advisable  under  the  rules,
regulations and other requirements of the Securities and Exchange Commission, or
other  securities  commission  having  jurisdiction,   any  applicable  Federal,
provincial or state  securities  law, any stock exchange upon which the Stock is
then listed and the  Committee may cause a legend or legends to be placed on any
such certificates to make appropriate reference to such restrictions.

                           (b)  EMPLOYMENT  MATTERS.  The  adoption  of the Plan
shall not confer upon any Optionee of the Company or any  Subsidiary,  any right
to  continued  employment  or,  in the case of an  Optionee  who is a  director,
continued service as a director,  with the Company or a Subsidiary,  as the case
may be, nor shall it  interfere  in any way with the right of the Company or any
Subsidiary to terminate the employment of any of its  employees,  the service of
any of its directors or the retention of any of its  consultants  or advisors at
any time.

                           (c)  LIMITATION OF LIABILITY.  No member of the Board
or the Committee,  or any officer or employee of the Company acting on behalf of
the  Board  or the  Committee,  shall  be  personally  liable  for  any  action,
determination, or interpretation taken or made in good faith with respect to the
Plan,  and all members of the Board or the Committee and each and any officer or
employee of the Company acting on their behalf shall, to the extent permitted by


                                       -8-
<PAGE>

law, be fully  indemnified  and  protected by the Company in respect of any such
action, determination or interpretation.

                           (d) REGISTRATION OF STOCK.  Notwithstanding any other
provision in the Plan, no Option may be exercised  unless and until the Stock to
be issued upon the exercise thereof has been registered under the Securities Act
and applicable  state  securities laws, or are, in the opinion of counsel to the
Company,  exempt from such  registration in the United States or exempt from the
prospectus   and   registration   requirements   under   applicable   provincial
legislation.  The Company shall not be under any  obligation  to register  under
applicable  federal  or state  securities  laws any Stock to be issued  upon the
exercise  of an  Option  granted  hereunder,  or to comply  with an  appropriate
exemption from registration under such laws or the laws of any province in order
to permit  the  exercise  of an Option  and the  issuance  and sale of the Stock
subject to such Option however,  the Company may in its sole discretion register
such Stock at such time as the Company shall  determine.  If the Company chooses
to comply with such an exemption from  registration,  the Stock issued under the
Plan may, at the direction of the  Committee,  bear an  appropriate  restrictive
legend restricting the transfer or pledge of the Stock represented  thereby, and
the  Committee  may also give  appropriate  stop  transfer  instructions  to the
Company's transfer agents.

                   SENIOR EXECUTIVE OFFICER STOCK OPTION PLAN

         1. PURPOSE OF THE PLAN.

         This  Senior  Executive  Officer  Stock  Option  Plan (the  "Plan")  is
intended  as an  incentive,  to retain in the employ of GST  TELECOMMUNICATIONS,
INC., a federally  chartered  Canadian  corporation with its principal office at
4317 N.E.  Thurston Way,  Vancouver,  Washington  98662 (the  "Company") and any
Subsidiary  of the Company,  within the meaning of Section  424(f) of the United
States  Internal  Revenue  Code of 1986,  as  amended  (the  "Code"),  as senior
executive officers, persons of training,  experience and ability, to attract new
senior executive officers whose services are considered  valuable,  to encourage
the sense of proprietorship and to stimulate the active interest of such persons
in the development and financial success of the Company and its Subsidiaries.

         It is further  intended that certain  options  granted  pursuant to the
Plan shall constitute  incentive stock options within the meaning of Section 422
of the Code (the  "Incentive  Options"),  while certain  other  options  granted
pursuant to the Plan shall be  nonqualified  stock  options  (the  "Nonqualified
Options").  Incentive Options and Nonqualified  Options are hereinafter referred
to collectively as "Options."

         The Company  intends that the Plan meet the  requirements of Rule 16b-3
("Rule 16b-3") promulgated under the Securities Exchange Act of 1934, as amended
(the  "Exchange  Act"),   and  that   transactions  of  the  type  specified  in
subparagraphs  (c) to (f)  inclusive of Rule 16b-3 by officers and  directors of
the Company  pursuant to the Plan will be exempt from the  operation  of Section
16(b) of the Exchange Act. In all cases, the terms,  provisions,  conditions and
limitations of the Plan shall be construed and  interpreted  consistent with the
Company's intent as stated in this Section 1.
<PAGE>

         2. ADMINISTRATION OF THE PLAN.

         The Board of Directors of the Company (the  "Board")  shall appoint and
maintain as administrator of the Plan a Committee (the  "Committee")  consisting
of two or more  Non-Employee  Directors (as such term is defined in Rule 16b-3),
which  shall  serve at the  pleasure  of the Board.  The  Committee,  subject to
Sections  3 and 5 hereof,  shall  have full  power and  authority  to  designate
recipients  of Options,  to determine  the terms and  conditions  of  respective
Option  agreements (which need not be identical) and to interpret the provisions
and  supervise the  administration  of the Plan.  The  Committee  shall have the
authority, without limitation, to designate which Options granted under the Plan
shall be  Incentive  Options and which  shall be  Nonqualified  Options.  To the
extent any Option does not qualify as an Incentive Option, it shall constitute a
separate Nonqualified Option.

         Subject to the  provisions of the Plan, the Committee  shall  interpret
the Plan and all  Options  granted  under the Plan,  shall make such rules as it
deems necessary for the proper  administration of the Plan, shall make all other
determinations  necessary or advisable  for the  administration  of the Plan and
shall correct any defects or supply any omission or reconcile any  inconsistency
in the Plan or in any  Options  granted  under the Plan in the manner and to the
extent that the Committee  deems  desirable to carry into effect the Plan or any
Options.  The act or  determination  of a majority of the Committee shall be the
act or  determination  of the Committee and any decision  reduced to writing and
signed by all of the members of the Committee  shall be fully effective as if it
had been made by a majority at a meeting duly held. Subject to the provisions of
the Plan, any action taken or  determination  made by the Committee  pursuant to
this and the other Sections of the Plan shall be conclusive on all parties.

         In the event that for any reason the  Committee  is unable to act or if
the  Committee at the time of any grant,  award or other  acquisition  under the
Plan of Options or Stock does not consist of two or more Non-Employee Directors,
then any such grant,  award or other  acquisition may be approved or ratified in
any other manner contemplated by subparagraph (d) of Rule 16b-3.

         3. DESIGNATION OF OPTIONEES.

         The persons  eligible for  participation  in the Plan as  recipients of
Options  (the  "Optionees")  shall  comprise  senior  executive  officers of the
Company or any Subsidiary;  provided that Incentive  Options may only be granted
to  senior  executive  officers  who  are  employees  of  the  Company  and  the
Subsidiaries. In selecting Optionees, and in determining the number of shares to
be covered by each Option  granted to Optionees,  the Committee may consider the
office or position held by the Optionee or the  Optionee's  relationship  to the
Company, the Optionee's degree of


                                       -2-
<PAGE>

responsibility  for and contribution to the growth and success of the Company or
any Subsidiary, the Optionee's length of service, age, promotions, potential and
any other factors that the Committee may consider relevant.  An Optionee who has
been granted an Option hereunder may be granted an additional Option or Options,
if the Committee shall so determine.

         4. STOCK RESERVED FOR THE PLAN.

         Subject to  adjustment  as  provided  in  Section 7 hereof,  a total of
600,000 of the Company's  Common  Shares (the  "Stock")  shall be subject to the
Plan.  The shares of Stock subject to the Plan shall consist of unissued  shares
or  previously  issued shares held by any  Subsidiary  of the Company,  and such
amount of shares of Stock shall be and is hereby reserved for such purpose.  Any
of such  shares of Stock  that may  remain  unsold  and that are not  subject to
outstanding  Options at the  termination  of the Plan shall cease to be reserved
for the  purposes  of the Plan,  but until  termination  of the Plan the Company
shall at all times  reserve a  sufficient  number of shares of Stock to meet the
requirements of the Plan.  Should any Option expire or be cancelled prior to its
exercise  in full or should the number of shares of Stock to be  delivered  upon
the exercise in full of an Option be reduced for any reason, the shares of Stock
theretofore  subject to such Option may be subject to future  Options  under the
Plan.

         5. TERMS AND CONDITIONS OF OPTIONS.

         Options  granted  under  the Plan  shall be  subject  to the  following
conditions  and  shall  contain  such  additional  terms  and  conditions,   not
inconsistent with the terms of the Plan, as the Committee shall deem desirable:

         (a) OPTION PRICE. The purchase price of each share of Stock purchasable
under an Incentive  Option shall be  determined  by the Committee at the time of
grant,  but shall not be less than  100% of the Fair  Market  Value (as  defined
below)  of such  share of Stock on the date the  Option  is  granted;  PROVIDED,
HOWEVER, that with respect to an Optionee who, at the time such Incentive Option
is granted,  owns  (within the meaning of Section  424(d) of the Code) more than
10% of the total combined voting power of all classes of stock of the Company or
of any Subsidiary,  the purchase price per share of Stock shall be at least 110%
of the Fair Market  Value per share of Stock on the date of grant.  The purchase
price of each share of Stock purchasable  under a Nonqualified  Option shall not
be less than 80% of the Fair Market Value of such share of Stock on the date the
Option  is  granted;  PROVIDED,  HOWEVER,  that an  Optionee  who is a  Canadian
taxpayer may require that any Nonqualified Option granted to him provide for the
purchase of shares of Stock upon  exercise  thereof at a price equal to the Fair
Market  Value per share of Stock on the date of grant.  The  exercise  price for
each Option shall be subject to adjustment as provided in Section 7


                                       -3-
<PAGE>

below.  Fair Market Value means the closing  price of publicly  traded shares of
Stock on the  principal  United  States  securities  exchange on which shares of
Stock are listed (if the shares of Stock are so listed),  or on the NASDAQ Stock
Market (if the shares of Stock are regularly quoted on the NASDAQ Stock Market),
or, if not so listed or regularly  quoted,  the mean between the closing bid and
asked prices of publicly traded shares of Stock in the over-the-counter  market,
or, if such bid and asked  prices  shall not be  available,  as  reported by any
nationally   recognized  quotation  service  selected  by  the  Company,  or  as
determined by the Committee in a manner  consistent  with the  provisions of the
Code. Anything in this Section 5(a) to the contrary notwithstanding, in no event
shall  the  purchase  price of a share of Stock be less than the  minimum  price
permitted  under  rules and  policies of the  American  Stock  Exchange  and the
Vancouver Stock Exchange.

         (b)  OPTION  TERM.  The  term of each  Option  shall  be  fixed  by the
Committee, but no Option shall be exercisable more than six years after the date
such Option is granted.

         (c)  EXERCISABILITY.  Subject to Section 5(j) hereof,  Options shall be
exercisable  at such time or times and subject to such terms and  conditions  as
shall be  determined  by the  Committee  at the time of grant.  No option may be
exercised to the extent that such exercise will cause the Company to issue, upon
exercise of options to purchase  shares of Stock granted by the Company  without
shareholder approval, that number of shares of Stock as equals or exceeds (i) 5%
of the number of outstanding shares of Stock in any 12-month period, or (ii) 10%
of the number of outstanding shares of Stock in any five-year period.

         (d) METHOD OF EXERCISE.  Options to the extent then  exercisable may be
exercised  in whole or in part at any time during the option  period,  by giving
written  notice to the  Company  specifying  the number of shares of Stock to be
purchased,  accompanied  by payment in full of the purchase  price,  in cash, by
check  or such  other  instrument  as may be  acceptable  to the  Committee.  As
determined by the Committee, in its sole discretion,  at or after grant, payment
in full or in part may also be made in the form of Stock  owned by the  Optionee
(based on the Fair  Market  Value of the Stock on the  trading  day  before  the
Option is  exercised).  An Optionee  shall have the right to dividends and other
rights of a stockholder  with respect to shares of Stock purchased upon exercise
of an Option after (i) the Optionee has given written notice of exercise and has
paid in full for such  shares  and (ii)  becomes a  stockholder  of record  with
respect thereto.

         (e)  NON-TRANSFERABILITY  OF OPTIONS.  Options are not transferable and
may be exercised  solely by the Optionee  during his lifetime or after his death
by the person or persons  entitled thereto under his will or the laws of descent
and distribution.


                                       -4-
<PAGE>

Any attempt to transfer,  assign,  pledge or otherwise dispose of, or to subject
to  execution,  attachment  or  similar  process,  any  Option  contrary  to the
provisions  hereof shall be void and  ineffective and shall give no right to the
purported transferee.

         (f) TERMINATION BY DEATH. Unless otherwise  determined by the Committee
at grant,  if any  Optionee's  employment  with or service to the Company or any
Subsidiary  terminates  by  reason  of  death,  the  Option  may  thereafter  be
exercised,  to the extent then exercisable (or on such accelerated  basis as the
Committee shall determine at or after grant), by the legal representative of the
estate or by the legatee of the Optionee  under the will of the Optionee,  for a
period of one year after the date of such death or until the  expiration  of the
stated  term of such  Option as  provided  under the Plan,  whichever  period is
shorter.

         (g) TERMINATION BY REASON OF DISABILITY. Unless otherwise determined by
the  Committee at grant,  if any  Optionee's  employment  with or service to the
Company  or  any  Subsidiary   terminates  by  reason  of  total  and  permanent
disability, any Option held by such Optionee may thereafter be exercised, to the
extent it was  exercisable at the time of  termination  due to Disability (or on
such accelerated basis as the Committee shall determine at or after grant),  but
may not be  exercised  after  30 days  after  the  date of such  termination  of
employment  or service or the  expiration  of the  stated  term of such  Option,
whichever  period is shorter;  provided,  however,  that,  if the Optionee  dies
within such 30 day period,  any  unexercised  Option held by such Optionee shall
thereafter be exercisable to the extent to which it was  exercisable at the time
of death for a period of one year after the date of such death or for the stated
term of such Option, whichever period is shorter.

         (h) TERMINATION BY REASON OF RETIREMENT. Unless otherwise determined by
the  Committee at grant,  if any  Optionee's  employment  with or service to the
Company or any Subsidiary terminates by reason of Normal or Early Retirement (as
such terms are defined  below),  any Option held by such Optionee may thereafter
be exercised to the extent it was exercisable at the time of such Retirement (or
on such  accelerated  basis as the Committee shall determine at or after grant),
but may not be  exercised  after 30 days after the date of such  termination  of
employment  or service or the  expiration  of the  stated  term of such  Option,
whichever  period is shorter;  provided,  however,  that,  if the Optionee  dies
within such 30 day period,  any  unexercised  Option held by such Optionee shall
thereafter be exercisable, to the extent to which it was exercisable at the time
of  death,  for a period  of one year  after  the date of such  death or for the
stated term of such Option, whichever period is shorter.


                                       -5-
<PAGE>

         For  purposes  of this  paragraph  (h),  Normal  Retirement  shall mean
retirement from active employment with the Company or any Subsidiary on or after
the normal  retirement  date specified in the  applicable  Company or Subsidiary
pension plan or if no such pension  plan,  age 65. Early  Retirement  shall mean
retirement from active employment with the Company or any Subsidiary pursuant to
the early retirement  provisions of the applicable Company or Subsidiary pension
plan or if no such pension plan, age 55.

         (i) OTHER TERMINATION.  Unless otherwise determined by the Committee at
grant,  if any  Optionee's  employment  with or  service  to the  Company or any
Subsidiary  terminates for any reason other than death,  Disability or Normal or
Early Retirement, the Option shall thereupon terminate,  except that the portion
of any Option that was exercisable on the date of such termination of employment
may be exercised for the lesser of 30 days after the date of  termination or the
balance of such Option's term if the  Optionee's  employment or service with the
Company or any  Subsidiary  is  terminated  by the  Company  or such  Subsidiary
without cause (the  determination as to whether  termination was for cause to be
made by the  Committee).  The  transfer  of an  Optionee  from the employ of the
Company to a Subsidiary, or vice versa, or from one Subsidiary to another, shall
not be deemed to  constitute a  termination  of  employment  for purposes of the
Plan.

         (j) LIMIT ON VALUE OF  INCENTIVE  OPTIONS.  The  aggregate  Fair Market
Value,  determined as of the date the Incentive Option is granted,  of Stock for
which  Incentive  Options  are  exercisable  for the first time by any  Optionee
during any calendar  year under the Plan (and/or any other stock option plans of
the Company or any Subsidiary) shall not exceed $100,000.

         (k) TRANSFER OF INCENTIVE  OPTION  SHARES.  The stock option  agreement
evidencing any Incentive  Options  granted under this Plan shall provide that if
the Optionee  makes a  disposition,  within the meaning of Section 424(c) of the
Code and  regulations  promulgated  thereunder,  of any share or shares of Stock
issued to him upon exercise of an Incentive Option granted under the Plan within
the two-year  period  commencing  on the day after the date of the grant of such
Incentive  Option or within a one-year  period  commencing  on the day after the
date of transfer of the share or shares to him  pursuant to the exercise of such
Incentive  Option, he shall,  within 10 days after such disposition,  notify the
Company  thereof  and  immediately  deliver to the  Company any amount of United
States federal income tax withholding required by law.

         (l) LIMITATION ON OPTIONS HELD BY ONE PERSON.  The aggregate  number of
shares of Stock  subject to options held by any one person shall not exceed that
number of shares as equals 5% of the outstanding shares of the Company.


                                       -6-
<PAGE>
         6. TERM OF PLAN.

         No Option  shall be  granted  pursuant  to the Plan on or after May 21,
2006, but Options theretofore granted may extend beyond that date.

         7.       CAPITAL CHANGE OF THE COMPANY.

         In  the   event   of   any   merger,   reorganization,   consolidation,
recapitalization,  stock  dividend,  or  other  change  in  corporate  structure
affecting  the Stock,  the  Committee  shall make an  appropriate  and equitable
adjustment in the number and kind of shares reserved for issuance under the Plan
and in the number  and option  price of shares  subject to  outstanding  Options
granted  under  the Plan,  to the end that  after  such  event  each  Optionee's
proportionate  interest shall be maintained as immediately before the occurrence
of such event.

         8. PURCHASE FOR INVESTMENT.

         Unless the Options and shares covered by the Plan have been  registered
under the United  States  Securities  Act of 1933,  as amended (the  "Securities
Act"), or the Company has determined that such registration is unnecessary, each
person  exercising  an Option  under the Plan may be  required by the Company to
give a  representation  in writing that he is  acquiring  the shares for his own
account for investment  and not with a view to, or for sale in connection  with,
the distribution of any part thereof.

         9. TAXES.

         The  Company  may make  such  provisions  as it may  deem  appropriate,
consistent with applicable law, in connection with any Options granted under the
Plan with respect to the  withholding  of any United States or Canadian taxes or
any other tax matters.

         10. EFFECTIVE DATE OF PLAN.

         The Plan shall be effective on May 22, 1996.

         11. AMENDMENT AND TERMINATION.

         The Board may amend,  suspend,  or terminate  the Plan,  except that no
amendment  shall be made that would impair the rights of any Optionee  under any
Option  theretofore  granted  without his consent,  and except that no amendment
shall be made which,  without the  approval of the  shareholders  of the Company
would:

               (a)  materially  increase the number of shares that may be issued
         under the Plan, except as is provided in Section 7;


                                       -7-
<PAGE>
               (b)  materially  increase the benefits  accruing to the Optionees
         under the Plan;

               (c) materially  modify the  requirements  as to  eligibility  for
         participation in the Plan;

               (d) decrease the  exercise  price of an Incentive  Option to less
         than  100% of the Fair  Market  Value per share of Stock on the date of
         grant thereof or the exercise  price of a  Nonqualified  Option to less
         than 80% of the Fair  Market  Value  per  share of Stock on the date of
         grant thereof; or

               (e) extend the term of any Option  beyond  that  provided  for in
         Section 5(b).

         The  Committee may amend the terms of any Option  theretofore  granted,
prospectively or retroactively, but no such amendment shall impair the rights of
any Optionee without his consent.  The Committee may also substitute new Options
for previously  granted  Options,  including  options  granted under other plans
applicable to the  participant  and  previously  granted  Options  having higher
option prices, upon such terms as the Committee may deem appropriate.

         12. GOVERNMENT REGULATIONS.

         The Plan,  and the grant and  exercise  of Options  hereunder,  and the
obligation of the Company to sell and deliver  shares under such Options,  shall
be subject to all applicable laws, rules and regulations,  and to such approvals
by any governmental  agencies or national  securities  exchanges  (including the
American Stock Exchange and Vancouver Stock Exchange) as may be required.

         13. GENERAL PROVISIONS.

         (a) CERTIFICATES.  All certificates for shares of Stock delivered under
the Plan shall be subject to such stop transfer orders and other restrictions as
the  Committee  may deem  advisable  under  the  rules,  regulations  and  other
requirements  of the Securities  and Exchange  Commission,  or other  securities
commission  having  jurisdiction,  any applicable  Federal,  provincial or state
securities  law, any stock  exchange upon which the Stock is then listed and the
Committee may cause a legend or legends to be placed on any such certificates to
make appropriate reference to such restrictions.

         (b) EMPLOYMENT MATTERS.  The adoption of the Plan shall not confer upon
any Optionee of the Company or any Subsidiary, any right to continued employment
or,  in the  case of an  Optionee  who is a  director,  continued  service  as a
director,  with the  Company or a  Subsidiary,  as the case may be, nor shall it
interfere in any way with the right of the Company or any


                                       -8-
<PAGE>
Subsidiary to terminate the employment of any of its  employees,  the service of
any of its directors or the retention of any of its  consultants  or advisors at
any time.

         (c)  LIMITATION OF LIABILITY.  No member of the Board or the Committee,
or any officer or  employee of the Company  acting on behalf of the Board or the
Committee,  shall  be  personally  liable  for  any  action,  determination,  or
interpretation  taken or made in good  faith with  respect to the Plan,  and all
members of the Board or the  Committee  and each and any  officer or employee of
the Company  acting on their behalf  shall,  to the extent  permitted by law, be
fully  indemnified  and  protected by the Company in respect of any such action,
determination or interpretation.

         (d) REGISTRATION OF STOCK.  Notwithstanding  any other provision in the
Plan,  no Option may be  exercised  unless and until the Stock to be issued upon
the exercise thereof has been registered under the Securities Act and applicable
state securities laws, or are, in the opinion of counsel to the Company,  exempt
from such  registration  in the United States or exempt from the  prospectus and
registration  requirements under applicable provincial legislation.  The Company
shall not be under any obligation to register under applicable  federal or state
securities  laws any Stock to be issued upon the  exercise of an Option  granted
hereunder,  or to comply with an appropriate  exemption from registration  under
such laws or the laws of any  province  in order to permit  the  exercise  of an
Option and the  issuance and sale of the Stock  subject to such Option  however,
the Company may in its sole  discretion  register such Stock at such time as the
Company shall determine. If the Company chooses to comply with such an exemption
from registration,  the Stock issued under the Plan may, at the direction of the
Committee,  bear an appropriate  restrictive  legend restricting the transfer or
pledge  of the  Stock  represented  thereby,  and the  Committee  may also  give
appropriate stop transfer instructions to the Company's transfer agents.

                          GST TELECOMMUNICATIONS, INC.

                   SENIOR OPERATING OFFICER STOCK OPTION PLAN

         1. PURPOSE OF THE PLAN.

         This  Senior  Operating  Officer  Stock  Option  Plan (the  "Plan")  is
intended  as an  incentive,  to retain in the employ of GST  TELECOMMUNICATIONS,
INC., a federally  chartered  Canadian  corporation with its principal office at
4317 N.E.  Thurston Way,  Vancouver,  Washington  98662 (the  "Company") and any
Subsidiary  of the Company,  within the meaning of Section  424(f) of the United
States  Internal  Revenue  Code of 1986,  as  amended  (the  "Code"),  as senior
operating  officers,   operating  officers,  senior  executive  officers,  other
officers, employees and directors, persons of training,  experience and ability,
to attract new senior operating officers,  operating officers,  senior executive
officers, other officers,  employees and directors whose services are considered
valuable,  to encourage the sense of proprietorship  and to stimulate the active
interest of such persons in the development and financial success of the Company
and its Subsidiaries.

         It is further  intended that certain  options  granted  pursuant to the
Plan shall constitute  incentive stock options within the meaning of Section 422
of the Code (the  "Incentive  Options"),  while certain  other  options  granted
pursuant to the Plan shall be  nonqualified  stock  options  (the  "Nonqualified
Options").  Incentive Options and Nonqualified  Options are hereinafter referred
to collectively as "Options."

         The Company  intends that the Plan meet the  requirements of Rule 16b-3
("Rule 16b-3") promulgated under the Securities Exchange Act of 1934, as amended
(the  "Exchange  Act"),   and  that   transactions  of  the  type  specified  in
subparagraphs  (c) to (f)  inclusive of Rule 16b-3 by officers and  directors of
the Company  pursuant to the Plan will be exempt from the  operation  of Section
16(b) of the Exchange Act. In all cases, the terms,  provisions,  conditions and
limitations of the Plan shall be construed and  interpreted  consistent with the
Company's intent as stated in this Section 1.
<PAGE>

         2. ADMINISTRATION OF THE PLAN.

         The Board of Directors of the Company (the  "Board")  shall appoint and
maintain as administrator of the Plan a Committee (the  "Committee")  consisting
of two or more  Non-Employee  Directors (as such term is defined in Rule 16b-3),
which  shall  serve at the  pleasure  of the Board.  The  Committee,  subject to
Sections  3 and 5 hereof,  shall  have full  power and  authority  to  designate
recipients  of Options,  to determine  the terms and  conditions  of  respective
Option  agreements (which need not be identical) and to interpret the provisions
and  supervise the  administration  of the Plan.  The  Committee  shall have the
authority, without limitation, to designate which Options granted under the Plan
shall be  Incentive  Options and which  shall be  Nonqualified  Options.  To the
extent any Option does not qualify as an Incentive Option, it shall constitute a
separate Nonqualified Option.

         Subject to the  provisions of the Plan, the Committee  shall  interpret
the Plan and all  Options  granted  under the Plan,  shall make such rules as it
deems necessary for the proper  administration of the Plan, shall make all other
determinations  necessary or advisable  for the  administration  of the Plan and
shall correct any defects or supply any omission or reconcile any  inconsistency
in the Plan or in any  Options  granted  under the Plan in the manner and to the
extent that the Committee  deems  desirable to carry into effect the Plan or any
Options.  The act or  determination  of a majority of the Committee shall be the
act or  determination  of the Committee and any decision  reduced to writing and
signed by all of the members of the Committee  shall be fully effective as if it
had been made by a majority at a meeting duly held. Subject to the provisions of
the Plan, any action taken or  determination  made by the Committee  pursuant to
this and the other Sections of the Plan shall be conclusive on all parties.

         In the event that for any reason the  Committee  is unable to act or if
the  Committee at the time of any grant,  award or other  acquisition  under the
Plan of Options or Stock does not consist of two or more Non-Employee Directors,
then any such grant,  award or other  acquisition may be approved or ratified in
any other manner contemplated by subparagraph (d) of Rule 16b-3.

         3. DESIGNATION OF OPTIONEES.

         The persons  eligible for  participation  in the Plan as  recipients of
Options (the "Optionees")  shall comprise senior operating  officers,  operating
officers, senior executive officers, other officers,  employees and directors of
the  Company or any  Subsidiary;  provided  that  Incentive  Options may only be
granted to senior  operating  officers,  operating  officers,  senior  executive
officers,  other  officers,  employees  and  directors  who are employees of the
Company and the  Subsidiaries.  In selecting  Optionees,  and in determining the
number of shares to be covered by each Option


                                       -2-
<PAGE>

granted to Optionees,  the Committee may consider the office or position held by
the  Optionee or the  Optionee's  relationship  to the Company,  the  Optionee's
degree of  responsibility  for and contribution to the growth and success of the
Company or any Subsidiary,  the Optionee's length of service,  age,  promotions,
potential and any other factors that the  Committee  may consider  relevant.  An
Optionee who has been granted an Option  hereunder  may be granted an additional
Option or Options, if the Committee shall so determine.

         4. STOCK RESERVED FOR THE PLAN.

         Subject to  adjustment  as  provided  in  Section 7 hereof,  a total of
900,000 of the Company's  Common  Shares (the  "Stock")  shall be subject to the
Plan.  The shares of Stock subject to the Plan shall consist of unissued  shares
or  previously  issued shares held by any  Subsidiary  of the Company,  and such
amount of shares of Stock shall be and is hereby reserved for such purpose.  Any
of such  shares of Stock  that may  remain  unsold  and that are not  subject to
outstanding  Options at the  termination  of the Plan shall cease to be reserved
for the  purposes  of the Plan,  but until  termination  of the Plan the Company
shall at all times  reserve a  sufficient  number of shares of Stock to meet the
requirements of the Plan.  Should any Option expire or be cancelled prior to its
exercise  in full or should the number of shares of Stock to be  delivered  upon
the exercise in full of an Option be reduced for any reason, the shares of Stock
theretofore  subject to such Option may be subject to future  Options  under the
Plan.

         5. TERMS AND CONDITIONS OF OPTIONS.

         Options  granted  under  the Plan  shall be  subject  to the  following
conditions  and  shall  contain  such  additional  terms  and  conditions,   not
inconsistent with the terms of the Plan, as the Committee shall deem desirable:

         (a) OPTION PRICE. The purchase price of each share of Stock purchasable
under an Incentive  Option shall be  determined  by the Committee at the time of
grant,  but shall not be less than  100% of the Fair  Market  Value (as  defined
below)  of such  share of Stock on the date the  Option  is  granted;  PROVIDED,
HOWEVER, that with respect to an Optionee who, at the time such Incentive Option
is granted,  owns  (within the meaning of Section  424(d) of the Code) more than
10% of the total combined voting power of all classes of stock of the Company or
of any Subsidiary,  the purchase price per share of Stock shall be at least 110%
of the Fair Market  Value per share of Stock on the date of grant.  The purchase
price of each share of Stock purchasable  under a Nonqualified  Option shall not
be less than 80% of the Fair Market Value of such share of Stock on the date the
Option  is  granted;  PROVIDED,  HOWEVER,  that an  Optionee  who is a  Canadian
taxpayer may require that any Nonqualified Option granted to him provide for the
purchase of shares of Stock upon


                                       -3-
<PAGE>

exercise thereof at a price equal to the Fair Market Value per share of Stock on
the date of grant.  The  exercise  price for each  Option  shall be  subject  to
adjustment  as provided in Section 7 below.  Fair Market Value means the closing
price  of  publicly  traded  shares  of  Stock on the  principal  United  States
securities  exchange on which shares of Stock are listed (if the shares of Stock
are so  listed),  or on the  NASDAQ  Stock  Market  (if the  shares of Stock are
regularly quoted on the NASDAQ Stock Market),  or, if not so listed or regularly
quoted,  the mean  between the closing bid and asked  prices of publicly  traded
shares of Stock in the over-the-counter market, or, if such bid and asked prices
shall not be  available,  as reported  by any  nationally  recognized  quotation
service  selected by the Company,  or as determined by the Committee in a manner
consistent with the provisions of the Code. Anything in this Section 5(a) to the
contrary  notwithstanding,  in no event shall the  purchase  price of a share of
Stock be less than the minimum price  permitted  under rules and policies of the
American Stock Exchange and the Vancouver Stock Exchange.

         (b)  OPTION  TERM.  The  term of each  Option  shall  be  fixed  by the
Committee, but no Option shall be exercisable more than six years after the date
such Option is granted.

         (c)  EXERCISABILITY.  Subject to Section 5(j) hereof,  Options shall be
exercisable  at such time or times and subject to such terms and  conditions  as
shall be  determined  by the  Committee  at the time of grant.  No option may be
exercised to the extent that such exercise will cause the Company to issue, upon
exercise of options to purchase  shares of Stock granted by the Company  without
shareholder approval, that number of shares of Stock as equals or exceeds (i) 5%
of the number of outstanding shares of Stock in any 12-month period, or (ii) 10%
of the number of outstanding shares of Stock in any five-year period.

         (d) METHOD OF EXERCISE.  Options to the extent then  exercisable may be
exercised  in whole or in part at any time during the option  period,  by giving
written  notice to the  Company  specifying  the number of shares of Stock to be
purchased,  accompanied  by payment in full of the purchase  price,  in cash, by
check  or such  other  instrument  as may be  acceptable  to the  Committee.  As
determined by the Committee, in its sole discretion,  at or after grant, payment
in full or in part may also be made in the form of Stock  owned by the  Optionee
(based on the Fair  Market  Value of the Stock on the  trading  day  before  the
Option is  exercised).  An Optionee  shall have the right to dividends and other
rights of a stockholder  with respect to shares of Stock purchased upon exercise
of an Option after (i) the Optionee has given written notice of exercise and has
paid in full for such  shares  and (ii)  becomes a  stockholder  of record  with
respect thereto.


                                       -4-
<PAGE>

         (e)  NON-TRANSFERABILITY  OF OPTIONS.  Options are not transferable and
may be exercised  solely by the Optionee  during his lifetime or after his death
by the person or persons  entitled thereto under his will or the laws of descent
and distribution.  Any attempt to transfer,  assign, pledge or otherwise dispose
of, or to subject  to  execution,  attachment  or  similar  process,  any Option
contrary to the provisions  hereof shall be void and  ineffective and shall give
no right to the purported transferee.

         (f) TERMINATION BY DEATH. Unless otherwise  determined by the Committee
at grant,  if any  Optionee's  employment  with or service to the Company or any
Subsidiary  terminates  by  reason  of  death,  the  Option  may  thereafter  be
exercised,  to the extent then exercisable (or on such accelerated  basis as the
Committee shall determine at or after grant), by the legal representative of the
estate or by the legatee of the Optionee  under the will of the Optionee,  for a
period of one year after the date of such death or until the  expiration  of the
stated  term of such  Option as  provided  under the Plan,  whichever  period is
shorter.

         (g) TERMINATION BY REASON OF DISABILITY. Unless otherwise determined by
the  Committee at grant,  if any  Optionee's  employment  with or service to the
Company  or  any  Subsidiary   terminates  by  reason  of  total  and  permanent
disability, any Option held by such Optionee may thereafter be exercised, to the
extent it was  exercisable at the time of  termination  due to Disability (or on
such accelerated basis as the Committee shall determine at or after grant),  but
may not be  exercised  after  30 days  after  the  date of such  termination  of
employment  or service or the  expiration  of the  stated  term of such  Option,
whichever  period is shorter;  provided,  however,  that,  if the Optionee  dies
within such 30 day period,  any  unexercised  Option held by such Optionee shall
thereafter be exercisable to the extent to which it was  exercisable at the time
of death for a period of one year after the date of such death or for the stated
term of such Option, whichever period is shorter.

         (h) TERMINATION BY REASON OF RETIREMENT. Unless otherwise determined by
the  Committee at grant,  if any  Optionee's  employment  with or service to the
Company or any Subsidiary terminates by reason of Normal or Early Retirement (as
such terms are defined  below),  any Option held by such Optionee may thereafter
be exercised to the extent it was exercisable at the time of such Retirement (or
on such  accelerated  basis as the Committee shall determine at or after grant),
but may not be  exercised  after 30 days after the date of such  termination  of
employment  or service or the  expiration  of the  stated  term of such  Option,
whichever  period is shorter;  provided,  however,  that,  if the Optionee  dies
within such 30 day period,  any  unexercised  Option held by such Optionee shall
thereafter be exercisable, to the extent to which it was exercisable at the time
of death, for a period of one year after


                                       -5-
<PAGE>

the date of such death or for the stated term of such Option,  whichever  period
is shorter.

         For  purposes  of this  paragraph  (h),  Normal  Retirement  shall mean
retirement from active employment with the Company or any Subsidiary on or after
the normal  retirement  date specified in the  applicable  Company or Subsidiary
pension plan or if no such pension  plan,  age 65. Early  Retirement  shall mean
retirement from active employment with the Company or any Subsidiary pursuant to
the early retirement  provisions of the applicable Company or Subsidiary pension
plan or if no such pension plan, age 55.

         (i) OTHER TERMINATION.  Unless otherwise determined by the Committee at
grant,  if any  Optionee's  employment  with or  service  to the  Company or any
Subsidiary  terminates for any reason other than death,  Disability or Normal or
Early Retirement, the Option shall thereupon terminate,  except that the portion
of any Option that was exercisable on the date of such termination of employment
may be exercised for the lesser of 30 days after the date of  termination or the
balance of such Option's term if the  Optionee's  employment or service with the
Company or any  Subsidiary  is  terminated  by the  Company  or such  Subsidiary
without cause (the  determination as to whether  termination was for cause to be
made by the  Committee).  The  transfer  of an  Optionee  from the employ of the
Company to a Subsidiary, or vice versa, or from one Subsidiary to another, shall
not be deemed to  constitute a  termination  of  employment  for purposes of the
Plan.

         (j) LIMIT ON VALUE OF  INCENTIVE  OPTIONS.  The  aggregate  Fair Market
Value,  determined as of the date the Incentive Option is granted,  of Stock for
which  Incentive  Options  are  exercisable  for the first time by any  Optionee
during any calendar  year under the Plan (and/or any other stock option plans of
the Company or any Subsidiary) shall not exceed $100,000.

         (k) TRANSFER OF INCENTIVE  OPTION  SHARES.  The stock option  agreement
evidencing any Incentive  Options  granted under this Plan shall provide that if
the Optionee  makes a  disposition,  within the meaning of Section 424(c) of the
Code and  regulations  promulgated  thereunder,  of any share or shares of Stock
issued to him upon exercise of an Incentive Option granted under the Plan within
the two-year  period  commencing  on the day after the date of the grant of such
Incentive  Option or within a one-year  period  commencing  on the day after the
date of transfer of the share or shares to him  pursuant to the exercise of such
Incentive  Option, he shall,  within 10 days after such disposition,  notify the
Company  thereof  and  immediately  deliver to the  Company any amount of United
States federal income tax withholding required by law.

         (l) LIMITATION ON OPTIONS HELD BY ONE PERSON.  The aggregate  number of
shares of Stock subject to options held by any


                                       -6-
<PAGE>

one  person  shall  not  exceed  that  number  of  shares  as  equals  5% of the
outstanding shares of the Company.

         6. TERM OF PLAN.

         No Option  shall be  granted  pursuant  to the Plan on or after May 21,
2006, but Options theretofore granted may extend beyond that date.

         7. CAPITAL CHANGE OF THE COMPANY.

         In  the   event   of   any   merger,   reorganization,   consolidation,
recapitalization,  stock  dividend,  or  other  change  in  corporate  structure
affecting  the Stock,  the  Committee  shall make an  appropriate  and equitable
adjustment in the number and kind of shares reserved for issuance under the Plan
and in the number  and option  price of shares  subject to  outstanding  Options
granted  under  the Plan,  to the end that  after  such  event  each  Optionee's
proportionate  interest shall be maintained as immediately before the occurrence
of such event.

         8. PURCHASE FOR INVESTMENT.

         Unless the Options and shares covered by the Plan have been  registered
under the United  States  Securities  Act of 1933,  as amended (the  "Securities
Act"), or the Company has determined that such registration is unnecessary, each
person  exercising  an Option  under the Plan may be  required by the Company to
give a  representation  in writing that he is  acquiring  the shares for his own
account for investment  and not with a view to, or for sale in connection  with,
the distribution of any part thereof.

         9. TAXES.

         The  Company  may make  such  provisions  as it may  deem  appropriate,
consistent with applicable law, in connection with any Options granted under the
Plan with respect to the  withholding  of any United States or Canadian taxes or
any other tax matters.

         10. EFFECTIVE DATE OF PLAN.

         The Plan shall be effective on May 22, 1996.

         11. AMENDMENT AND TERMINATION.

         The Board may amend,  suspend,  or terminate  the Plan,  except that no
amendment  shall be made that would impair the rights of any Optionee  under any
Option  theretofore  granted  without his consent,  and except that no amendment
shall be made which,  without the  approval of the  shareholders  of the Company
would:


                                       -7-
<PAGE>

              (a)  materially  increase  the number of shares that may be issued
         under the Plan, except as is provided in Section 7;

              (b)  materially  increase the benefits  accruing to the  Optionees
         under the Plan;

              (c)  materially  modify the  requirements  as to  eligibility  for
         participation in the Plan;

              (d)  decrease the  exercise  price of an Incentive  Option to less
         than  100% of the Fair  Market  Value per share of Stock on the date of
         grant thereof or the exercise  price of a  Nonqualified  Option to less
         than 80% of the Fair  Market  Value  per  share of Stock on the date of
         grant thereof; or

              (e) extend  the term of any Option  beyond  that  provided  for in
         Section 5(b).

         The  Committee may amend the terms of any Option  theretofore  granted,
prospectively or retroactively, but no such amendment shall impair the rights of
any Optionee without his consent.  The Committee may also substitute new Options
for previously  granted  Options,  including  options  granted under other plans
applicable to the  participant  and  previously  granted  Options  having higher
option prices, upon such terms as the Committee may deem appropriate.

         12. GOVERNMENT REGULATIONS.

         The Plan,  and the grant and  exercise  of Options  hereunder,  and the
obligation of the Company to sell and deliver  shares under such Options,  shall
be subject to all applicable laws, rules and regulations,  and to such approvals
by any governmental  agencies or national  securities  exchanges  (including the
American Stock Exchange and Vancouver Stock Exchange) as may be required.

         13. GENERAL PROVISIONS.

         (a) CERTIFICATES.  All certificates for shares of Stock delivered under
the Plan shall be subject to such stop transfer orders and other restrictions as
the  Committee  may deem  advisable  under  the  rules,  regulations  and  other
requirements  of the Securities  and Exchange  Commission,  or other  securities
commission  having  jurisdiction,  any applicable  Federal,  provincial or state
securities  law, any stock  exchange upon which the Stock is then listed and the
Committee may cause a legend or legends to be placed on any such certificates to
make appropriate reference to such restrictions.

         (b) EMPLOYMENT MATTERS.  The adoption of the Plan shall not confer upon
any Optionee of the Company or any


                                       -8-
<PAGE>
Subsidiary, any right to continued employment or, in the case of an Optionee who
is  a  director,  continued  service  as  a  director,  with  the  Company  or a
Subsidiary, as the case may be, nor shall it interfere in any way with the right
of the Company or any  Subsidiary  to  terminate  the  employment  of any of its
employees,  the service of any of its  directors or the  retention of any of its
consultants or advisors at any time.

         (c)  LIMITATION OF LIABILITY.  No member of the Board or the Committee,
or any officer or  employee of the Company  acting on behalf of the Board or the
Committee,  shall  be  personally  liable  for  any  action,  determination,  or
interpretation  taken or made in good  faith with  respect to the Plan,  and all
members of the Board or the  Committee  and each and any  officer or employee of
the Company  acting on their behalf  shall,  to the extent  permitted by law, be
fully  indemnified  and  protected by the Company in respect of any such action,
determination or interpretation.

         (d) REGISTRATION OF STOCK.  Notwithstanding  any other provision in the
Plan,  no Option may be  exercised  unless and until the Stock to be issued upon
the exercise thereof has been registered under the Securities Act and applicable
state securities laws, or are, in the opinion of counsel to the Company,  exempt
from such  registration  in the United States or exempt from the  prospectus and
registration  requirements under applicable provincial legislation.  The Company
shall not be under any obligation to register under applicable  federal or state
securities  laws any Stock to be issued upon the  exercise of an Option  granted
hereunder,  or to comply with an appropriate  exemption from registration  under
such laws or the laws of any  province  in order to permit  the  exercise  of an
Option and the  issuance and sale of the Stock  subject to such Option  however,
the Company may in its sole  discretion  register such Stock at such time as the
Company shall determine. If the Company chooses to comply with such an exemption
from registration,  the Stock issued under the Plan may, at the direction of the
Committee,  bear an appropriate  restrictive  legend restricting the transfer or
pledge  of the  Stock  represented  thereby,  and the  Committee  may also  give
appropriate stop transfer instructions to the Company's transfer agents.

defined in Article VIII hereof, or any occurrence that would constitute an Event
of Default with the giving of notice or the lapse of time, or both, has occurred

not include the proposed delivery  dates(s)),  in form acceptable to Lender, for

the Effective  Date within  Network  Locations  with the purchase  price of each
Switch  and  related  Equipment  being not less than One  Million  Five  Hundred

occurred  and is  continuing  and  (ii)  Lender  has  determined,  in  its  sole
discretion,  that it desires to make such  loans,  and  subject to the terms and
conditions  hereof,  and unless the  commitment  shall have been  terminated  in
accordance with the terms hereof,  Lender shall, upon Borrower's  request (which

             (c) USE OF LOAN  PROCEEDS.  Borrower  covenants and agrees that the
proceeds  of each  Interim  Loan  shall be used  solely  to  finance  Borrower's
purchase  of (i) Lender  Equipment  to be used  solely in any  Network  and (ii)
Borrower's purchase of Non- Lender Equipment to be used solely in a Network.

             (d)  LIMITATION  ON  VENDOR  ADVANCES;  ADVANCE  DATE  FOR  INTERIM
NON-LENDER  EQUIPMENT LOAN. The proceeds of any Vendor Advance used  exclusively
to  reimburse  Borrower  for  Non-Lender  Equipment  to be used  at any  Network
Location,  when  aggregated  with  all  prior  Vendor  Advances  used to pay for
Non-Lender Equipment for all Network Locations, as of the date such proceeds are
advanced,  shall not exceed the  aggregate  amount of the Loans made to Borrower
hereunder for the acquisition of Lender  Equipment for all Network  Location(s).
An Interim Loan, to the extent that it  constitutes a Vendor  Advance,  shall be
deemed  advanced to Borrower  hereunder,  and interest  shall commence to accrue
with  respect to such Vendor  Advance,  on the date that Lender has (i) received
from Borrower and accepted in accordance  with SECTION  4.2(J)  hereof:  (A) the
invoice  for the  Non-Lender  Equipment  financed  thereby  and (B) the proof of
payment of such  invoice,  and (ii)  advanced  such Vendor  Advance  proceeds to
Borrower in accordance with the instructions described in subsection (h) of this
Section;  PROVIDED,  HOWEVER,  that no Vendor  Advance shall be made to Borrower
more than six (6) months  prior to the  "SCHEDULED  SHIP  DATE" of the  relevant
Switch or Upgraded  Switch as set forth in the firm  irrevocable  purchase order
relating to said Switch or Upgraded Switch.  If, for any reason,  Borrower fails
or refuses to take  delivery of any Switch or  Upgraded  Switch on or before its
Scheduled Ship Date  ("UNDELIVERED  LENDER  EQUIPMENT")  and Lender has made any
Vendor  Advance(s) to Borrower for the  acquisition of Non-Lender  Equipment for
the Network to which the Undelivered  Lender Equipment was to be delivered,  the
Interim  Loan  relating  to the  Undelivered  Lender  Equipment  shall be deemed
advanced to  Borrower on the  Scheduled  Ship Date for such  Undelivered  Lender
Equipment. Lender shall transport and store such Undelivered Lender Equipment on
behalf of Borrower at Borrower's  expense.  All the terms and conditions of this
Agreement and all obligations and  responsibilities  of Borrower relating to the
delivered  Lender  Equipment  (except  those  terms and  conditions  relating to
possession and maintenance by Borrower of Lender Equipment after delivery) shall
be  applicable  to such  Undelivered  Lender  Equipment  and the  Loan  relating
thereto.

             (e) ADVANCE  DATE FOR INTERIM  LENDER  EQUIPMENT  LOAN.  An Interim
Loan, to the extent that it is a Lender Equipment Loan, shall be deemed advanced
to Borrower  hereunder,  the Lender  Equipment to be financed  thereby  shall be
deemed paid for,  and  interest  shall  commence to accrue with  respect to such
Interim Loan,  thirty (30) days after shipment of such Lender  Equipment and the
date the invoice for such Lender  Equipment is issued to Borrower or thirty (30)
days  after the date of  invoice  for  engineering,  installation  and  services
relating to such Lender Equipment is issued to Borrower, whichever occurs last.

             (f)  FINANCING  FEE.  With respect to each Vendor  Advance,  Lender
shall fully earn,  concurrent  with the  disbursement  thereof,  a financing fee
equal to one percent (1%) the amount of such Vendor Advance.  The amount of each
financing fee earned by

                                       11

<PAGE>

Lender (the  "FINANCING  FEE AMOUNT") shall be paid by Borrower to Lender within
thirty (30) days after the Advance Date of the related Interim Loan.

             (g) PROCEDURE  FOR PROPER  REQUEST.  Borrower  shall give Lender at
least  five (5)  Business  Days'  prior  written  notice  of each  Interim  Loan
requested to be made.  In each case,  such notice shall be in the form  attached
hereto as EXHIBIT C  ("NOTICE"),  shall be  irrevocable  and shall  specify  the
aggregate  amount of the proposed Interim Loan, the intended use of such Interim
Loan proceeds, and the specific bank account (including the identity of the bank
and the account  number) to which  Lender  shall  transfer  the  proceeds of the
Vendor Advance portion, if any, of the proposed Interim Loan. Such Notice, to be
effective,  must be received by Lender not later than 12:00 noon,  Eastern Time,
on the fifth (5th)  Business Day prior to the borrowing  date  specified in such
Notice.  In the event and to the extent that any such Notice relates to proceeds
of an Interim  Loan to be used to purchase  Non-Lender  Equipment  that does not
constitute  Approved  Third-Party  Product  identified  in SCHEDULE  1.1 hereto,
Lender shall  promptly  determine and notify  Borrower  within five (5) Business
Days whether it is prepared to recognize such  Non-Lender  Equipment as Approved
Third-Party  Product  and  finance the  purchase  of such  Non-Lender  Equipment
through a Vendor Advance. Lender and Borrower agree to use their best efforts in
good faith to resolve any  disagreement  as to whether any Non-Lender  Equipment
constitutes Approved Third-Party Product.  Lender shall make the proceeds of any
Vendor Advance available to Borrower at the bank account specified in the Notice
in U.S. dollars in immediately available funds.

             (h) ADEQUATE CASH.  Notwithstanding  the provisions of this Section
2.1,  Lender shall be obligated to advance any Interim Loan only if, at the time
such Interim Loan is to be advanced,  Guarantor  has Adequate Cash in the amount
of not less than  Twenty-Five  Million Dollars  ($25,000,000).  If the amount of
Adequate  Cash is  insufficient  as  provided in this  subparagraph,  and if the
Interim Loan was to be a Lender  Equipment  Loan,  Borrower shall be relieved of
its  obligation to purchase the related Lender  Equipment and, if delivered,  it
shall be returned to Lender at the direction of Lender at  Borrower's  sole cost
and expense.

         2.2 THE NOTE. The Loans shall be evidenced by a promissory  note in the
form of EXHIBIT B hereto (the "NOTE").  Lender is hereby  authorized by Borrower
to  endorse  on the  schedule  attached  to the  Note  an  appropriate  notation
evidencing  the date  and  amount  of each  Interim  Loan,  and the date and the
principal  amount of each  Term Loan  thereunder;  PROVIDED,  HOWEVER,  that the
failure of Lender to provide such endorsement, and other information on the Note
or schedule shall not in any manner affect the obligation of Borrower to repay a
Loan in accordance with the terms of the Note.

         2.3 TERM LOANS.  Each Interim Loan shall be converted  into a term loan
(a "TERM LOAN") on the next Conversion Date after the date of such Interim Loan.
Such Term Loan shall continue to be evidenced by the Note.

SECTION 2.9 hereof,  each Interim Loan shall bear interest  during each Interest
Period therefor at the Interim Loan Rate for such Interest  Period.  The Interim
Loan Rate shall be  computed on the basis of the actual  number of days  elapsed

be due and payable by Borrower on the first  Conversion  Date following the date
of the making of the Lender  Equipment Loan or Vendor  Advance  relating to such
Interim Loan.

             (b) TERM LOAN INTEREST  RATE.  Subject to the provisions of SECTION

interest from the date of its conversion  from an Interim Loan to a Term Loan at
the Term Loan  Rate.  The Term Loan Rate shall be  computed  on the basis of the
actual  number of days  elapsed over a year of 360 days and Term Loan Rate shall
be adjusted semi-annually on the last business day prior to January 1 and July 1
of each year during the term of such Term Loan,  which  adjustment  dates may be

any Term Loan shall be due and payable by Borrower on the last  Business  Day of
each calendar quarter during the term thereof. Borrower shall make interest only

following the related Conversion Date. Thereafter, interest accrued with respect
to the Term Loans and the Term Loan principal amounts outstanding under the Note

quarter  during  the term  hereof as set  forth in this  SECTION  2.5(A)  AND IN

(24)  consecutive  quarterly  installments  commencing on the same date that the
fifth (5th) consecutive  quarterly  installment of interest with respect to such
Term Loan is payable on the Note,  with the amount of principal  due and payable
on each such  quarterly  installment  date pursuant to this SECTION 2.5(B) to be

                  Quarterly Installment           Principal Amount
                  ---------------------           ----------------

         2.6 DEFAULT RATE OF INTEREST.  If Borrower shall default in the payment
of the  principal of or interest on the Note,  Borrower  shall,  on demand,  pay
interest  on any  amount  overdue  on the  Note at a rate  that is  equal to the
Applicable  Rate with respect to the Note plus two percent  (2%),  from the date
such payment is due to the date of actual payment.  If Borrower shall default in
the payment of any amount  payable by it hereunder  (other than principal of and
interest on any of the Loans),  Borrower shall,  on demand,  pay interest on any
such  overdue  amount at a rate that is equal to the  average of the  Applicable
Rates on all Loans then  outstanding  plus two percent (2%),  from the date such
payment is due to the date of actual payment.

         2.7 OPTIONAL PREPAYMENT OF NOTE; MANDATORY PREPAYMENT OF NOTE.

             (a) Borrower shall have the right at any time to prepay any Note of
Borrower,  in whole or in part,  without premium or penalty,  upon at least five
(5) Business Day's prior written notice to Lender, in integral  multiples of one
hundred  thousand  dollars  ($100,000).  Any  prepayment of less than the entire
aggregate  outstanding  balance  of the  Loans  should be  applied  first to the
payment of all accrued  interest on the amount so prepaid to and  including  the
date of  prepayment,  and  second to the  payment  of the  required  payment  of
principal  due  under  the  Note in the  inverse  order of the  maturity  of the
installments hereof.

             (b) Each notice of prepayment  pursuant to  subsection  (a) of this
section shall specify the principal amount to be prepaid and the prepayment date
on which such principal shall be prepaid,  shall be irrevocable and shall commit
the Borrower giving such prepayment notice to prepay such principal amount. Upon
any  prepayment  pursuant  to this  section,  Borrower  shall not be entitled to
reborrow from Lender hereunder the principal amount prepaid.

             (c) If (i) the aggregate outstanding principal balance of the Phase
I Loans exceeds the Phase I Cap or (ii) if the aggregate  outstanding  principal
balance of the Phase II Loans  exceeds the Phase II Cap, then in each such case,
Borrower is obligated to immediately  repay to Lender,  upon notice from Lender,
(i) the  amount by which the  aggregate  outstanding  principal  balance  of the
related Loans  exceeds the Phase I Principal  Cap or Phase II Principal  Cap, as
applicable,  plus (ii) all accrued and unpaid interest on such excess  principal
up to the date of repayment.

         2.8 PAYMENT, ETC. All payments by Borrower hereunder and under the Note

on which such payment shall be due. Interest in respect of any Loan hereunder
shall accrue from the first day following such Loan up to and including the date
on which such Loan is paid in full.

         2.9 MAXIMUM LAWFUL INTEREST RATE.  Notwithstanding any provision to the
contrary  contained  herein,  the total  liability  of  Borrower  for payment of
interest  pursuant  hereto and the Note,  including  any other  charges or other
amounts, to the extent such charges and other amounts are deemed to be interest,
shall not exceed the  maximum  amount of such  permitted  by law to be  charged,
collected,  or received  from  Borrower.  If any  payments  by Borrower  include
interest in excess of such a maximum  amount,  Lender shall apply such excess to
the reduction of the unpaid principal amount due pursuant hereto,  or if none is
due, such excess shall be refunded to Borrower.

         2.10  INDEMNIFICATION FOR FAILURE TO BORROW.  Borrower agrees to pay to
Lender,  upon the Lender's  request,  such amount or amounts as shall compensate
the Lender for any loss,  cost or expense  incurred by the Lender (as reasonably
determined  by the  Lender) as a result of any  failure by Borrower to borrow an
Interim Loan on the date for such  borrowing  specified  in the relevant  Notice
under SECTION 2.1(G) hereof,  such compensation to include,  without limitation,
an amount  equal to any loss or  expense  incurred  by Lender in respect of such
proposed  Interim Loan during the period from the date of receipt by Borrower of
such  Notice to the last day of such  Interest  Period,  if the rate of interest
obtainable  by the Lender upon the  redeployment  of an amount of funds equal to
the  amount of such  proposed  Interim  Loan is less  than the rate of  interest
applicable  to such  Interim  Loan or such Term Loan,  as  applicable,  for such
Interest Period;  provided,  however, that Borrower shall not be responsible for
any such loss if the  failure to borrow is caused by any willful act or omission
of Lender, including,  Lender's unreasonable failure to make any Interim Loan in
accordance  with Section  2.1(g) or 2.1(h).  The Lender's  determination  of the
amount  of any such  loss or  expense,  when set  forth in a  written  notice to
Borrower,  containing  the Lender's  calculation  thereof in reasonable  detail,
shall be conclusive, absent manifest error.

time to time (to the extent  necessary) to permit Lender's new products (as such
products become available),  including, without limitation,  Newbridge ATM/Frame
relay,  to the  type  of  Lender  Equipment  to be  financed  pursuant  to  this
Agreement.

         2.12 LEASES. Borrower covenants and agrees that all Equipment purchased
by Borrower and financed pursuant to this Agreement, to the extent that the same
shall  be  operated  and  maintained  by a  Borrower  Affiliate  rather  than by
Borrower,  shall be operated and  maintained  by such  Borrower  Affiliate  only
pursuant to the terms of a Lease between  Borrower and such Borrower  Affiliate,
which Lease shall be substantially in the form attached hereto as EXHIBIT J.

         2.13  SECURITY  AGREEMENT.  Borrower  covenants and agrees that it will
cause each Borrower  Affiliate to enter into the Security  Agreement in favor of
Lender, substantially in the form attached hereto as EXHIBIT H.

         2.14 EXTENSION.  Lender and Borrower agree that in the year immediately
preceding the Commitment Termination Date they will discuss the possibility of a
three (3)-year

                                       15

extension of the Commitment  Termination  Date, which extension shall occur only
if the parties mutually agree upon the terms and conditions thereof.

principal  amount of any Loan to the extent that the  proceeds of such Loan were

dollars ($5,000,000) (in the case of Guarantor) when due and payable (whether by

in the  agreement  or  instrument  relating to such  indebtedness;  or any other
default  or  event  under  any  agreement  or  instrument  relating  to any such
indebtedness  or any other  event,  shall  occur and  shall  continue  after the

prepayment)  prior to the stated maturity  thereof as a result of any such event
of default; or

for the  operation  by Borrower of the  Business  shall not be obtained or shall
cease to be in full force and  effect,  which in respect of a license of the FCC

effect or shall not be enforceable in accordance with its terms, or any security
interest or lien granted pursuant thereto shall fail to be perfected, other than

             (n) Either Borrower or Guarantor fails to comply with any provision

             (o) Ownership of any Borrower Affiliate shall have been transferred
so that it is no longer wholly owned by Borrower or an Affiliate.

         8.2 TERMINATION OF COMMITMENT; ACCELERATION. Upon the occurrence and at
any time during the continuance of any Event of Default, Lender may:

             (a)  by  notice  to  Borrower,  terminate  Lender's  Commitment  to
Borrower to make Loans hereunder; and

             (b) declare the  Obligations  to be  immediately  due and  payable,
whereupon the Obligations shall be immediately due and payable without notice of
any kind;  PROVIDED,  HOWEVER,  that if an Event of Default described in SECTION
8.1(E)  OR  8.1(F)  shall  exist  or  occur,   all  of  the  Obligations   shall
automatically, without declaration or notice of any kind, be immediately due and
payable.

         8.3  WAIVER OF  DEMAND.  Demand,  presentment,  protest  and  notice of
nonpayment  are hereby  waived by Borrower.  Borrower also waives the benefit of
all  valuation,  appraisal  and  exemption  laws  to  the  extent  permitted  by
applicable law.

         8.4  RIGHTS AND  REMEDIES  GENERALLY.  If an Event of  Default  occurs,
Lender shall have,  in addition to any other  rights and  remedies  contained in
this  Agreement  or in any of the other  Loan  Documents,  all of the rights and
remedies  of a secured  party under the Code and other  applicable  laws and all
other rights and  remedies by law,  all of which  rights and  remedies  shall be
cumulative,  and  non-exclusive,  to the extent permitted by law. In addition to
all such  rights  and  remedies,  the sale,  lease or other  disposition  of the
Collateral,  or any part thereof,  by Lender after the occurrence of an Event of
Default  may be for cash,  credit or any  combination  thereof,  and  Lender may
purchase  all or any part of the  Collateral  at public sale held in  compliance
with the procedures set forth in the Code, or, if permitted by law, private sale
held in compliance  with the  procedures  set forth in the Code,  and in lieu of
actual payment of such purchase  price,  may set off the amount of such purchase
price against the  Obligations  then owing.  Any sales of the  Collateral may be
adjourned  from time to time with or without  notice.  Lender  may,  in its sole
discretion,  cause  the  Collateral  to  remain  on  Borrower's  or  a  Borrower
Affiliate's premises,  at Borrower's expense,  pending sale or other disposition
of the  Collateral.  Lender  shall  have the  right  to  conduct  such  sales on
Borrower's  or a  Borrower  Affiliate's  premises,  at  Borrower's  expense,  or
elsewhere,  on such occasion or occasions as Lender may see fit. Lender's rights
under this Section shall be  enforceable  to the extent  permitted by applicable
law.

         8.5 ENTRY  UPON  PREMISES  AND  ACCESS TO  INFORMATION.  Following  the
occurrence and during the continuance of an Event of Default,  Lender shall have
the right to enter upon the premises of Borrower where the Collateral is located
(or is believed to be located) without any obligation to pay rent to Borrower or
a Borrower  Affiliate,  or any other  place or places  where the  Collateral  is
believed to be located and kept,  and render the  Collateral  unusable or remove
the Collateral  therefrom to the premises of Lender or any agent of

                                       37

<PAGE>

Lender,  for such time as Lender may desire,  in order effectively to collect or
liquidate  the  Collateral,  and/or  Lender may  require  Borrower or a Borrower
Affiliate to assemble the  Collateral and make it available to Lender at a place
or places to be  designated  by  Lender.  Lender  shall have the right to obtain
access to Borrower's data processing equipment or a Borrower Affiliate, computer
hardware and software  relating to the Collateral  during normal  business hours
and to use all of the foregoing  and the  information  contained  therein in any
manner Lender deems  reasonably  appropriate in connection  with the exercise of
its rights and remedies. Lender's rights under this Section shall be enforceable
to the extent permitted by applicable law.

         8.6 SALE OR OTHER  DISPOSITION  OF  COLLATERAL  BY  LENDER.  Any notice
required to be given by Lender of a sale,  lease or other  disposition by Lender
pursuant  to  ARTICLE  VIII  with  respect  to any of the  Collateral  which  is
deposited  in the  United  States  mails,  certified  postage  prepaid  and duly
addressed to Borrower and Guarantor and, each of them, at the address  specified
in SECTION 9.1 below,  at least five (5)  Business  Days prior to such  proposed
action shall constitute fair and reasonable  notice to Borrower and Guarantor of
any such action. The net proceeds realized by Lender upon any such sale or other
disposition, after deduction for the expense of retaking, holding, preparing for
sale, selling or the like and the reasonable  attorneys' fees and legal expenses
incurred by Lender in connection therewith,  shall be applied as provided herein
toward satisfaction of the Obligations. Lender shall account to Borrower for any
surplus realized upon such sale or other disposition,  and Borrower shall remain
liable for any deficiency.  The commencement of any action,  legal or equitable,
or the rendering of any judgment or decree for any  deficiency  shall not affect
Lender's security interest in the Collateral. Borrower agrees that Lender has no
obligation to preserve  rights to the Collateral  against any other Persons.  In
connection with the exercise of any remedies pursuant to this section, Lender is
hereby  granted a license  or other  right to use,  without  charge,  Borrower's
labels,  patents,  copyrights,  rights of use of any name, trade secrets,  trade
names,  trademarks,  service marks and advertising  matter, or any property of a
similar  nature,  as it  pertains  to the  Collateral,  and,  to the  extent not
prohibited  by the terms of any  applicable  license  or  franchise  agreements,
Borrower's rights under all licenses and all franchise agreements shall inure to
Lender's  benefit until the Obligations are paid in full.  Lender's rights under
this Section shall be enforceable to the extent permitted by applicable law.

         8.7 LENDER NOT LIABLE.  Lender shall not be  responsible  or liable for
any  shortage,  discrepancy,  damage,  loss or  destruction  of any  part of the
Collateral or of any instrument  received in payment therefor or for any damages
resulting therefrom (except to the extent such loss shall be finally adjudicated
or otherwise conclusively determined to have been caused by the gross negligence
or willful  misconduct of Lender).  Lender shall not, under any circumstances or
in any event  whatsoever,  have any  liability  for any error or omission of any
kind made in the  settlement,  collection  or payment  of any of the  Collateral
(except  to the  extent  such loss shall be  finally  adjudicated  or  otherwise
conclusively  determined to have been caused by the gross  negligence or willful
misconduct of Lender). The costs of collection and enforcement,  including,  but
not limited to, reasonable counsel fees and out-of-

                                       38

<PAGE>
pocket  expenses,  shall be  borne  solely  by  Borrower,  whether  the same are
incurred by Lender or Borrower.

         8.8 RIGHT OF SET-OFF. Upon the occurrence and during the continuance of
any Event of Default,  Lender is hereby  authorized at any time and from time to
tine, to the fullest  extent  permitted by law, to set off and apply any and all
deposits (general or special, time or demand,  provisional or final) at any time
held and other  indebtedness or other obligations at any time owing by Lender to
or for  the  credit  or the  account  of  Borrower  against  any  and all of the
obligations of Borrower now or hereafter existing under this Agreement.

courier service or any telegraphic  communications  equipment of the sender,  in
each case  addressed to such party as provided in this Section or in  accordance
with the latest unrevoked direction from such party.

         9.2 NO WAIVERS; AMENDMENTS.

             (a) No failure or delay of Lender to exercise  any right  hereunder
or under any other Loan Document  shall operate as a waiver  thereof,  nor shall
any single or partial exercise of any such right,  preclude any other or further
exercise  thereof or the exercise of any other right. No waiver of any provision
of this  Agreement or any other Loan  Document  nor consent to any  departure by
Borrower  therefrom shall in any event be effective  unless the same shall be in
writing and signed by Lender, and then such waiver or consent shall be effective
only in the specific  instance and for the purpose for which given. No notice or
demand on  Borrower in any case shall  entitle  Borrower to any other or further
notice or demand in similar or other circumstances.

<PAGE>

             (b) Neither  this  Agreement  nor any other Loan  Documents  may be
amended or modified  except  pursuant to an agreement or  agreements  in writing
executed by Borrower and Lender.

         9.3 GOVERNING LAW AND  JURISDICTION.  THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS  SHALL BE  CONSTRUED IN  ACCORDANCE  WITH AND GOVERNED BY THE INTERNAL
LAWS OF THE STATE OF NEW YORK,  WITHOUT  GIVING  EFFECT TO ANY CONFLICTS OF LAWS
PRINCIPLES.  BORROWER AND LENDER CONSENT TO THE JURISDICTION OF ANY LOCAL, STATE
OR FEDERAL COURT LOCATED IN NEW YORK CITY IN THE STATE OF NEW YORK AND WAIVE ANY
OBJECTION  RELATING TO IMPROPER  VENUE OR FORUM NON CONVENIENS TO THE CONDUCT OF
ANY PROCEEDING BY SUCH COURT.

         9.4 EXPENSES; DOCUMENTARY TAXES. Borrower shall be obligated to pay all
reasonable  out-of-pocket expenses incurred by Lender in connection with (i) the
creation,  perfection,  priority or protection  of the Liens in the  Collateral,
including the  reasonable  attorneys'  fees incurred both prior to and after the
Effective Date to perfect the Lien in the  Collateral,  and (ii) the enforcement
of Lender's rights in connection  with this Agreement,  any other Loan Documents
or the Collateral, including all reasonable attorneys' fees and related expenses
and costs;  provided,  however,  that  Borrower  shall not be  obligated  to pay
expenses incurred by Lender on or prior to the Effective Date to the extent that
they  exceed  $100,000.  Borrower  agrees to  indemnify  Lender from and hold it
harmless  against any  documentary  taxes,  assessments  or charges  made by any
governmental authority by reason of the execution and delivery of this Agreement
or any other Loan Document.

         9.5  EQUITABLE  RELIEF.  Borrower  recognizes  that,  in the event that
Borrower  fails to  perform,  observe or  discharge  any of its  obligations  or
liabilities under this Agreement,  or any other Loan Document, any remedy at law
may prove to be inadequate  relief to Lender;  therefore,  Borrower  agrees that
Lender,  if Lender so  requests,  shall be entitled to temporary  and  permanent
injunctive  relief in any such case  without  the  necessity  of proving  actual
damages.

         9.6 INDEMNIFICATION; LIMITATION OF LIABILITY.

             (a) Borrower agrees to protect,  indemnify and hold harmless Lender
and each of its  officers,  directors,  employees,  attorneys,  consultants  and
agents (collectively the "INDEMNITIES") from and against any and all liabilities
(including  tort,  negligence  and  strict  liabilities),  obligations,  losses,
damages,  penalties,  actions,  judgments,  suits, claims,  costs,  expenses and
disbursements of any kind or nature whatsoever  (including,  without limitation,
the reasonable  fees and  disbursements  of counsel for and  consultants of such
Indemnities in connection  with any  investigative,  administrative  or judicial
proceeding,  whether  or not  such  Indemnities  shall  be  designated  a  party
thereto),  which may be  imposed  on,  incurred  by, or  asserted  against  such
Indemnities (whether direct, indirect, or consequential and whether

                                       41

<PAGE>

based on any federal or state laws or other  statutory  regulations,  including,
without   limitation,   securities,   environmental   and  commercial  laws  and
regulations, under common law or at equitable cause or on contract or otherwise)
in any manner  relating to or arising out of this  Agreement or any of the other
Loan Documents,  or any act, event or transaction  related or attendant thereto,
the agreements of Lender contained  herein,  the making of Loans, the management
of such Loans or the Collateral (including any liability under federal, state or
local  environmental  laws or  regulations)  or the use or  intended  use of the
proceeds of such Loans  hereunder  (collectively,  the  "INDEMNIFIED  MATTERS");
provided that neither  Borrower nor Guarantor  shall have any  obligation to any
Indemnitee  hereunder with respect to Indemnified Matters caused by or resulting
from the willful  misconduct  or gross  negligence  of such  Indemnitee.  To the
extent that the undertaking to indemnify, pay and hold harmless set forth in the
preceding  sentence may be  unenforceable  because it is violative of any law or
public  policy,  Borrower shall  contribute  the maximum  portion which they are
permitted  to  pay  and  satisfy  under  applicable  law,  to  the  payment  and
satisfaction of all Indemnified Matters incurred by the Indemnities.

             (b) To the extent permitted by applicable law, no claim may be made
by  Borrower  or any  other  Person  against  Lender  or any of its  affiliates,
directors,  officers,  employees,  agents,  attorneys  or  consultants  for  any
special, indirect, consequential or punitive damages in respect of any claim for
breach of contract or any other theory of liability arising out of or related to
the transactions  contemplated by any of the Loan Documents or any act, omission
or event occurring in connection therewith; and Borrower hereby waives, releases
and  agrees  not to sue upon any  claim  for any such  damages,  whether  or not
accrued  and  whether or not known or  suspected  to exist in its favor,  to the
extent  permitted by applicable  law.  Neither Lender nor any of its affiliates,
directors, officers, employees, agents, attorneys or consultants shall be liable
for any action taken or omitted to be taken by it or them under or in connection
with any of the Loan Documents,  except for its or their own gross negligence or
willful misconduct.

             (c) If Borrower  fails to pay promptly when due to any other Person
monies which it is required to pay by reason of any provision in this Agreement,
Lender may, but need not, pay the same and Borrower agrees to promptly reimburse
Lender for such  payment;  PROVIDED,  HOWEVER,  Lender  may not pay any  amounts
described  in this  sentence the validity of which  Borrower is  contesting,  in
proceedings  which are being  diligently  pursued,  and for which  Borrower  has
created reserves therefor which are satisfactory to Lender. Any payments made by
Lender shall not constitute: (i) an agreement by Lender to make similar payments
in the future, or (ii) a waiver by Lender of any Event of Default.

         9.7 SURVIVAL OF AGREEMENTS,  REPRESENTATIONS  AND WARRANTIES,  ETC. All
warranties,  representations,  indemnities and covenants made by Borrower in any
Loan Document survive the execution and delivery of this Agreement and the other
Loan  Documents  and the  making  of the  Obligations  and shall  survive  until
repayment in full in immediately available funds of all Obligations (after which
period Lender shall only have a right of  indemnification  from Borrower for any
breach of any such warranties,  representations  and covenants during the

                                       42

<PAGE>

period for which such warranties,  representations and covenants are in effect);
PROVIDED, HOWEVER, that if the Lender for any reason is required to disgorge any
payment  with  respect  to  the  Obligations  after  the  date  that  all of the
Obligations  are  repaid  in full  in  immediately  available  funds,  then  all
warranties, representations and covenants made by Borrower or Guarantor shall be
reinstated  as though such full payment had not  occurred and shall  continue in
effect until repayment in full in immediately available funds of all Obligations
that are restored and/or created as a result of such payment disgorgement.

         9.8 SUCCESSORS AND ASSIGNS.  Borrower may not assign or transfer any of
its rights or obligations  hereunder  without  Lender's  prior written  consent.
Lender may not assign or transfer any of its rights or obligations  hereunder to
any Person (other than to Siemens Credit Corporation),  without Borrower's prior
written  consent,  which consent shall not be unreasonably  withheld or delayed.
Borrower  agrees  that it will not assert  against  any  permitted  assignee  of
Lender,  including  Siemens Credit  Corporation,  any defense,  counterclaim  or
off-set that  Borrower may have against  Lender and that upon notice of any such
assignment or transfer,  it will pay all Obligations due under this Agreement to
such  assignee or  transferee.  Borrower  acknowledges  that any  assignment  or
transfer by Lender shall not materially  change Borrower's duties or obligations
under this  Agreement  nor shall it  materially  increase  the  burdens or risks
imposed on Borrower.

         9.9 SEVERABILITY.  In case any one or more of the provisions  contained
in this  Agreement  or any other  Loan  Document  shall be  invalid,  illegal or
unenforceable in any respect,  the validity,  legality and enforceability of the
remaining  provisions  contained  herein  and  therein  shall  not in any way be
affected or impaired thereby.

         9.10 COVER PAGE;  TABLE OF CONTENTS  AND  SECTION  HEADINGS.  The cover
page,  Table of Contents and section headings used herein are for convenience of
reference  only,  are not  part  of this  Agreement  and are not to  affect  the
construction of or be taken into consideration in interpreting this Agreement.

         9.11  COUNTERPARTS.  This Agreement may be signed in counterparts  with
the same  effect as if the  signatures  thereof  and  hereto  were upon the same
instrument.

         9.12  MARSHALLING;  PAYMENTS  SET  ASIDE.  Lender  shall  be  under  no
obligation  to  marshall  any assets in favor of  Borrower or any other party or
against  or in  payment of any or all of the  Obligations.  Notwithstanding  any
other provision  hereof, to the extent that Borrower makes a payment or payments

                        UNCONDITIONAL CONTINUING GUARANTY

                                (LOAN AGREEMENT)

         THIS  UNCONDITIONAL  CONTINUING  GUARANTY (this "GUARANTY") is made and
entered into as of September 4, 1996, by and between  Siemens  Stromberg-Carlson
("LENDER"),  whose  principal  place of business is located at 900 Broken  Sound
Parkway,  Boca  Raton,  Florida  33487 and GST USA,  Inc.  ("GUARANTOR"),  whose
address is 4317 Northeast Thurston Way, Vancouver, Washington 98662.

         1. GUARANTY.  In order to induce Lender, and in consideration  thereof,
to enter into that  certain  Loan and  Security  Agreement  dated as of the date
hereof (the "AGREEMENT"),  with GST Switchco,  Inc. ("BORROWER") and, subject to
Section  2  below,   Guarantor   unconditionally,   absolutely  and  irrevocably
guarantees  the  punctual  payment  when due,  whether  at stated  maturity,  by
acceleration  or  otherwise,  of all  obligations  of Borrower  now or hereafter
existing   to  Lender   under  the   Agreement   and  the  Note   (collectively,
"OBLIGATIONS"),  including,  but not limited to, the  repayment to Lender of all
sums  presently  due and owing,  and all sums that in the future  become due and
owing,  from Borrower to Lender  arising under the  Agreement.  All  capitalized
terms not otherwise  defined  herein shall have the same meaning as set forth in
the Agreement.

         2.  LIMITATION ON GUARANTOR'S  LIABILITY.  Guarantor's  liability under
this  Guaranty  shall be limited to the sum of (a) the lesser of (i)  fifty-five
percent (55%) of the principal and interest  outstanding under Loans, other than
Loans used by  Borrower  to finance  the  acquisition  Cable or (ii)  Forty-Five
Million  Dollars  ($45,000,000),  and  (b) one  hundred  percent  (100%)  of the
outstanding  principal and interest under Loans used to finance the  acquisition
of Cable and all reasonable  attorneys' fees and costs incurred by Lender in the
enforcement of the Agreement or this Guaranty.

         3. OBLIGATIONS.  The Obligations  include any and all loans,  advances,
indebtedness  and  other  obligations  owed by  Borrower  to  Lender  under  the
Agreement  of every  description,  whether now  existing or  hereafter  arising,
whether direct or indirect, fixed or contingent or liquidated or unliquidated.

         4.  ATTORNEY'S  FEES. If Lender incurs  attorney's fees relating to the
enforcement of this  Guaranty,  Guarantor  agrees to pay Lender such  reasonable
attorney's  fees  plus all  reasonable  costs  and  expenses  relating  thereto.
Guarantor  agrees to pay Lender's  reasonable  attorney's  fees  relating to any
action,  suit,  counterclaim,   post-judgment  motions,  bankruptcy  litigation,
appeal, arbitration or mediation relating to the enforcement of this Guaranty.

         5. WAIVERS.

            5.1. SCOPE OF RISK DEFENSES. Lender may at any time and from time to
time,  without  notice or the consent of  Guarantor,  and without  affecting  or
impairing the liability of Guarantor  hereunder,  do any of the  following:  (i)
renew,  modify,  or extend  (including  extensions beyond the original term) any
Obligations  of  Borrower,  of  its  customers,  of any  co-guarantors  (whether
hereunder  or under a  separate  instrument)  or of any other  party at any time
directly or contingently  liable for the payment of any said  Obligations;  (ii)
accept partial payments of said Obligations;  (iii) settle,  discharge,  release
(by operation of law or otherwise),  compound,  compromise, collect or liquidate
any of said Obligations and the security therefor in any manner; (iv) consent to
the  transfer or sale of  security,  or (v) bid and  purchase at any sale of any
security;  or (vi) change the terms of the Obligations,  including  increases or
decreases in payments or any interest rate adjustments.

            5.2.  PRIMARY  OBLIGATION  DEFENSES.  Guarantor waives any rights to
require Lender to (i) proceed against  Borrower or any other guarantor or party;
(ii)  proceed  against or exhaust any security  held from  Borrower or any other
guarantor;  or (iii)  pursue  any other  remedy in  Lender's  power  whatsoever.
Guarantor  waives any defense based on or arising out of any defense of Borrower
in respect of the Obligations,  whether such defense arises by operation of law,
bankruptcy of Borrower or otherwise,  including without limitation,  any defense
based on or arising out of any disability of Borrower or the unenforceability of
the  Obligations  from any  cause.  Guarantor  waives any  defense  based on any
applicable statute of limitations or statute of frauds.

            5.3.  COMMERCIALLY  REASONABLE SALE AND ANTI-DEFICIENCY LAWS. Lender
may, at Lender's  election,  foreclose on any security  held by Lender by one or
more judicial or nonjudicial sales, whether or not every aspect of any such sale
is  commercially  reasonable,  or exercise any other right or remedy  Lender may
have against  Borrower,  or any security,  without affecting or impairing in any
way the liability of Guarantor  except to the extent the  Obligations  have been
paid.  Guarantor  waives any defense arising out of any such election by Lender,
even  though  such  election  operates  to  impair  or  extinguish  any right of
reimbursement or subrogation or other right or remedy of Lender against Borrower
or any  security.  In the absence of agreeing to the waivers  contained  in this
Section  5.3,  Guarantor  may have the  right of  subrogation  or  reimbursement
against  Borrower.  For example,  if Lender elects to foreclose,  by nonjudicial
sale,  any deeds of trust  securing  any  indebtedness  of  Borrower  to Lender,
causing  Guarantor to lose any such rights or create  defenses to enforcement of
this Guaranty, Guarantor gives up any such potential defenses by agreeing to the
waivers  contained in this  Section 5.3.  Guarantor  also  expressly  waives any
defense or benefit  that may be  derived  from any "one form of action"  rule or
anti-deficiency  statute and all  suretyship  defenses it would  otherwise  have
under the laws of any state.

            5.4.  DISCLOSURE  DEFENSES.  Guarantor expressly waives all set-offs
and  counterclaims  and waives all  notices,  protests  and  demands  including,
without limitation,


                                        2


<PAGE>

notice  of  default  in the  payment  of rents or in the  performance  or in the
observance of any of the terms, provisions, covenants or conditions contained in
any agreement between Lender and Borrower.

            5.5.  IMPAIRMENT OF COLLATERAL  DEFENSE.  Guarantor expressly agrees
that the validity of this Guaranty and the obligations of Guarantor shall not be
terminated,  affected or impaired by reason of the waiving, delaying, exercising
or  non-exercising  of any of Lender's rights against  Borrower  pursuant to the
Agreement or against  Guarantor by reason of this Guaranty or as a result of the
substitution,  release,  repossession,  sale,  disposition or destruction of any
collateral or of the items leased or to be leased to Borrower.  Guarantor  shall
not be released or discharged,  either in whole or in part, by Lender's  failure
or delay (a) to perfect or continue the  perfection of any security  interest in
any  property  which  secures  the  Obligations  of Borrower to Lender or (b) to
protect the property covered by such security interest.

            5.6.  GUARANTOR'S  RIGHT TO REVOKE.  Guarantor  expressly waives the
right to revoke or terminate  this  Guaranty,  including any statutory  right of
revocation under the laws of any state.

         6.  FINANCIAL   CONDITION  OF  BORROWER.   Guarantor  (a)  assumes  all
responsibility for being and keeping informed of Borrower's  financial condition
and assets and of all other circumstances bearing upon the risk of nonpayment of
the  Obligations  and the nature,  scope and extent of the risks which Guarantor
assumes and incurs  hereunder  and (b) agrees that Lender  shall have no duty to
advise  Guarantor of  information  known to it regarding such  circumstances  or
risks.

         7.  SUBROGATION.  If an Event of Default has occurred and is continuing
under the  Agreement,  Guarantor  shall not  exercise  any  rights  which it may
acquire by way of subrogation under this Guaranty, by any payment made hereunder
or otherwise,  until all of the Obligations shall have been paid in full and the
obligation  of Lender  under the  Agreement  to make Loans shall have expired or
been  terminated.  If an Event of Default has  occurred and is  continuing,  any
amount that is paid to  Guarantor on account of such  subrogation  rights at any
time  prior  to the  later  of the  payment  in full of the  Obligations  or the
expiration  or  termination  of the  obligation of Lender under the Agreement to
make Loans,  shall be held in trust for the benefit of Lender and paid forthwith
to Lender to either,  in Lender's sole  discretion,  (x) be credited and applied
upon the Obligations, whether matured or unmatured, in accordance with the terms
of the  Agreement  or (y) be held  by  Lender  as  collateral  security  for any
Obligations thereafter existing. If (i) Guarantor makes payment to Lender of all
or any part of the  Obligations,  (ii) all the  Obligations are paid in full and
(iii) the  obligation of Lender under the Agreement to make Loans has expired or
terminated,  Lender  will,  at  Guarantor's  request,  execute  and  deliver  to
Guarantor appropriate documents,  without recourse and without representation or
warranty,  necessary to evidence the transfer by  subrogation to Guarantor of an
interest in the Obligations resulting from such payment by Guarantor.

                                        3

<PAGE>
         8.  RECOVERY OF  PREFERENCES.  If a claim of a preference  payment or a
claim of  fraudulent  transfer is made upon Lender at any time for  repayment or
recovery of any amount(s) or other value received by Lender, from any source, in
payment of or on  account of any of the  Obligations  guaranteed  hereunder  and
Lessor repays or otherwise  becomes  liable for all or any part of such claim by
reason of (i) any judgment,  decree or order of any court or administrative body
having  competent  jurisdiction or (ii) any settlement or compromise of any such
claim,  Guarantor  shall  remain  liable to Lender  hereunder  for the amount so
repaid or for which  Lender is  otherwise  liable to the same  extent as if such
amount(s) had never been  received by Lender,  notwithstanding  any  termination
hereof.

         9. REPRESENTATIONS AND WARRANTIES. Guarantor represents and warrants to
Lender as of the Effective Date that:

            9.1. It is a corporation  duly  organized,  validly  existing and in

<PAGE>

                 9.5.4.  do not result in the creation or imposition of any Lien

dated as of March 31, 1996 (the "BALANCE SHEET"),  attached hereto as EXHIBIT A.
As of the Effective Date, (a) the Balance Sheet fairly represents such company's

any  governmental  instrumentality  or  other  agency  now  pending,  or to  the
knowledge of Guarantor,  threatened  against Guarantor or affecting any property
or rights of  Guarantor  as to which  there is a  reasonable  possibility  of an
adverse determination which, if adversely  determined,  would in individually or
in the  aggregate  materially  impair  the  right of  Guarantor  to carry on its
business or would have any Material Adverse Effect;

            9.8.  Guarantor  has filed or caused to be filed all federal,  state

applicability  or  validity  of  which  are  being  contested  in good  faith by
appropriate proceedings with respect to which the Guarantor shall have set aside

where the  failure to file such  returns or pay such taxes would have a Material
Adverse Effect;

            9.9.  Guarantor  is not  in  default,  which  default  would  have a
Material  Adverse Effect:  (a) with respect to any judgment,  writ,  injunction,
decree, rule or regulation of any governmental  instrumentality or other agency,

<PAGE>

            9.10.  Guarantor has obtained any and all licenses,  authorizations,
certificates,  and approvals of any federal, state or local governmental agency,
authority or  instrumentality  having  jurisdiction over Guarantor  required for

have a Material Adverse Effect;

            9.11.  Guarantor's  operations  comply in all material respects with
all applicable federal, state or local laws and regulations where the failure to

not filed any notice under any federal or state law  indicating  past or present
treatment,  storage or disposal of a hazardous  waste or  reporting a Release of

respect to each employment  benefit plan subject to ERISA,  are in compliance in

(ii) no  "prohibitive  transaction"  or  "reportable  event",  as such terms are

defined  in, and is not  otherwise  subject to  regulation  under,  the  "Public
Utility Holding Company Act of 1935;" and

            9.15.  Guarantor  is  not  engaged  principally,  or as  one  of its

no part of the  proceeds of the Loans will be used to purchase or carry any such
margin  stock or to extend  credit to others for the  purpose of  purchasing  or
carrying  any  such  margin  stock  or for  the  purpose  that  violates,  or is

             10.2. Guarantor shall comply in all material respects with all laws

order and condition,  excepting ordinary wear and tear and obsolescence,  all of
its  properties  material to its operations  and make all  appropriate  repairs,

otherwise which, if unpaid, might become a Lien upon such properties or any part
thereof;  PROVIDED,  HOWEVER,  that  Guarantor  shall not be required to pay and
discharge  or to cause  to be paid and  discharged  any  such  tax,  assessment,
charge,  levy or claim so long as (i) the  validity or amount  thereof  shall be
contested  in good  faith by  appropriate  proceedings  diligently  pursued  and
Guarantor  shall set aside on its books such  reserves  as are  required by GAAP
with respect to any such tax, assessment, charge, levy or claim so contested and
(ii) Guarantor's failure to do so would not have a Material Adverse Effect.

             10.6. Guarantor shall furnish to Lender:

and  related  instruments,  agreements  and  documents  executed  by and between
Borrower and the Lender (as amended,  modified,  supplemented  or replaced  from
time  to  time,   the  "LOAN   DOCUMENTS"),   but  only  so  long  as  Guarantor
unconditionally  guarantees  the timely  performance  and payment by Borrower of
each and every obligation  under the Loan Documents,  subject to the limitations
stated herein.

also owns  (indirectly)  one hundred percent (100%) of the  outstanding  capital

Equipment to be leased by Affiliates  from Borrower and will receive  direct and
indirect benefit from the Lender's extension of credit to Borrower.

         SECTION 2.5 WAIVER.  Guarantor  hereby  waives  promptness,  diligence,
notice of acceptance  and any other notice with respect to any of the Guaranteed
Obligations  and this  Guaranty  and any  requirement  that the Lender  protect,
secure,  perfect or insure any security interest or lien or any property subject
thereto or exhaust  any right or take any action  against  the  Borrower  or any
other person or entity (including any other guarantor) or any collateral.

         SECTION 2.6 WAIVER OF SUBROGATION.  Guarantor hereby irrevocably waives
any claim or other  rights  which it may now or  hereafter  acquire  against the
Borrower that arise from the existence,  payment,  performance or enforcement of
Guarantor's  obligations  under  this  Guaranty  or  any  other  Loan  Document,
including   any   right   of   subrogation,   reimbursement,   exoneration,   or
indemnification,  any right to  participate in any claim or remedy of the Lender
against the  Borrower or any  collateral  which the Lender now has or  hereafter
acquires,  whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including the right to take or receive from the
Borrower,  directly or indirectly, in cash or other property or by set-off or in
any manner, payment or security on account of such claim or other rights. If any
amount shall be paid to Guarantor in violation of the preceding sentence and the
Guaranteed  Obligations  shall  not have  been paid in cash in full and the Loan
Documents  have not been  terminated,  such amount  shall be deemed to have been
paid to  Guarantor  for the benefit of, and held in trust for,  the Lender,  and
shall  forthwith  be paid to the  Lender to be  credited  and  applied  upon the
Guaranteed  Obligations,  whether matured or unmatured.  Guarantor  acknowledges
that  it  will  receive   direct  and  indirect   benefits  from  the  financing
arrangements contemplated by the Loan Agreement and the other Loan Documents and
that the waiver set forth in this Section is knowingly made in  contemplation of
such benefits.

         SECTION 2.7 SUCCESSORS,  TRANSFEREES AND ASSIGNS;  TRANSFERS, OF LOANS,
ETC. This Guaranty shall:

                  (a)  be binding upon Guarantor,  and its permitted successors,
         transferees and assigns;

         and

                  (b)  inure to the benefit of and be  enforceable by the Lender
         and its permitted successors, transferees and assigns.

Without  limiting the generality of clause (b), to the extent the Lender assigns
or otherwise  transfers (in whole or in part) any Loan or Loan Documents held by
it to any other person or entity,  such other  person or entity shall  thereupon
become vested with the  corresponding  rights and benefits granted to the Lender
under this Guaranty.

         SECTION 2.8  LIMITATION  OF  GUARANTY.  The  financial  obligations  of
Guarantor  hereunder  shall be limited in aggregate  amount to the lesser of (i)
forty-five percent (45%) of Borrower's aggregate  Obligations  outstanding under
the  Loan  Agreement  from  time to time or  (ii)  Twenty-Five  Million  Dollars
($25,000,000.00).

         SECTION 3.1 REPRESENTATIONS AND WARRANTIES. Guarantor hereby represents
and warrants to the Lender as follows:

                  (a)  Guarantor  is  a  corporation  duly  organized,   validly
         existing  and  in  good  standing  under  the  laws  of  its  state  of
         incorporation  and has full corporate power and authority to enter into
         this Guaranty and to carry out the transactions contemplated hereby and
         thereby.

                  (b)  The  execution and delivery by Guarantor of this Guaranty
         and the  consummation  by  Guarantor of the  transactions  contemplated
         hereby have been duly authorized by all necessary  corporate  action of
         Guarantor.  This  Guaranty  has been duly  executed  and  delivered  by
         Guarantor and  constitutes the legal,  valid and binding  obligation of
         Guarantor  enforceable  against Guarantor in accordance with its terms,
         subject,   as  to   enforcement   only,  to   bankruptcy,   insolvency,
         reorganization,  moratorium  or  similar  laws at the  time  in  effect
         affecting the enforceability of the rights of creditors generally.

                  (c)  The  execution  and  delivery  of this  Guaranty  and the
         consummation by Guarantor of the transactions  contemplated hereby have
         not  resulted,  and will not (with or without  the lapse of time or the
         giving of notice or both) result, (i) in any breach of any of the terms
         or provisions of, or constitute a default under,  the charter or bylaws
         of Guarantor, any agreement, license or other instrument, any law, rule
         or regulation  or any  judgment,  decree or order of any court to which
         Guarantor is a party or by which its property may be bound,  or (ii) in
         the creation or imposition of any claim,  lien charge or encumbrance of
         any-nature  whatsoever  upon, or give to others any claim,  interest or
         right,  with  respect to any of the  properties,  assets,  contracts or
         licenses of Guarantor.

                                    ARTICLE 4

binding upon Guarantor and its successors,  permitted  transferees and permitted
assigns and shall inure to the benefit of and be  enforceable  by the Lender and
its successors, transferees and assigns (to the full extent provided pursuant to
SECTION 2.7); PROVIDED,  HOWEVER,  that Guarantor may not transfer or assign any

and no such assignment,  if permitted,  will operate to relieve Guarantor of its
obligations hereunder.

         SECTION 4.3 AMENDMENTS, ETC. No amendment or waiver of any provision of
this Guaranty nor consent to any departure by Guarantor  therefrom  shall in any
event be effective unless the same shall

prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition  or  unenforceability  without
