         INTERNATIONAL WIRELESS COMMUNICATIONS HOLDINGS, INC. AND SUBSIDIARY

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

    NATURE OF BUSINESS 

    International Wireless Communications Holdings, Inc. ("IWC Holdings") was
    incorporated in Delaware in July 1996 as a holding company whose primary
    assets are all of the issued and outstanding capital stock of International
    Wireless Communications, Inc. ("IWC") and a note receivable from IWC in a
    principal amount equal to the net proceeds from the Debt Offering (as
    defined below).  IWC was incorporated in Delaware in January 1992 and
    develops, owns and operates wireless communications companies in emerging
    markets in Asia and Latin America.  These local wireless businesses
    ("LWBs") provide a variety of communication services, including cellular,
    wireless local loop ("WLL"), enhanced capacity trunked radio ("ECTR") and
    paging.  Together with its strategic partners, IWC has interests in Brazil,
    China, India, Indonesia, Malaysia, Mexico, New Zealand, Pakistan, Peru, and
    the Philippines.

    The Company's investments to date have principally been in the early 
    stage development of LWBs.  In addition, the Company intends to pursue 
    additional investment opportunities.  The Company believes that its 
    existing cash balance is sufficient to meet its operating and 
    contractual obligations through fiscal 1997.  It is not sufficient, 
    however, to meet the Company's business objective of participation in 
    additional equity rounds to finance the infrastructure buildout of its 
    operating and nonoperating LWBs.  The ability of the Company to make 
    additional investments is dependent on the availability of external 
    financing.  In the event the Company is unable to obtain external 
    financing it may ultimately be unable to either maintain its existing 
    ownership interests or fully realize the underlying potential value of 
    the LWBs.

    In August 1996, the Company issued and sold 196,720 units, each consisting
    of a $1,000 principal amount 14% Senior Discount Note due 2001 (an
    "Original Note," and, collectively, the "Original Notes") and one warrant
    to purchase 11.638 shares of Common Stock (a "Warrant," and, collectively,
    the "Warrants"), for total gross proceeds of $100 million (the "Debt
    Offering").  In November 1996, pursuant to the indenture agreement that
    governs the Original Notes (the "Indenture"), the Company exchanged new 14%
    Senior Secured Discount Notes due 2001 (the "Exchange Notes") which were
    registered under the Securities Act of 1933, as amended (the "1933 Act"),
    for the Original Notes.  The terms of the Exchange Notes are substantially
    identical (including principal amount, interest rate, maturity, security
    and ranking) to the terms of the Original Notes.  (The Exchange Notes and
    the Original Notes are referred to collectively herein as the "Notes.")


    In connection with the Debt Offering, IWC Holdings and IWC completed a
    reorganization in which IWC became a wholly owned subsidiary of IWC
    Holdings through the conversion of each share of the then outstanding
    capital stock of IWC into forty shares of the corresponding class and
    series of stock of IWC Holdings (the "Stock Conversion"). All data related
    to shares and per share amounts for all periods presented have been
    adjusted to reflect the effect of the reorganization and the Stock
    Conversion.

    In the opinion of management, the accompanying unaudited financial
    statements of IWC Holdings and its subsidiary, IWC (together, the
    "Company"), reflect all adjustments (consisting only of normal recurring
    adjustments) considered necessary for a fair presentation of the Company's
    financial condition, results of operation and cash flows for the periods
    presented.  These financial statements should be read in conjunction with
    the Company's audited consolidated financial statements as of December 31,
    1995 and 1996, and for each of the years in the three-year period ended
    December 31, 1996, including the notes thereto.  The results of operations
    for the three months ended March 31, 1997 are not necessarily indicative of
    results that may be expected for the year ended December 31, 1997.  

    BASIS OF CONSOLIDATION

    The accompanying consolidated financial statements of the Company include
    the accounts of IWC, its wholly owned subsidiaries, SRC Servicos de Radio
    Comunicacoes Ltda. ("SRC"), TeamTalk Limited ("TeamTalk"), New Zealand
    Wireless Limited ("New Zealand Wireless"), International Wireless
    Communications Asia Holdings, B.V. ("IWC Asia B.V."), International
    Wireless Communications Latin America Holdings, Limited 

                                       7.

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


    ("IWC Latin America") and International Wireless Communications Asia Holding
    N.V. ("IWC Asia N.V.")  and four majority-owned subsidiaries, M/S Mobilcom 
    (Pte) Ltd. ("Mobilcom Pakistan"), PeruTel S.A. ("PeruTel"), Star Telecom 
    Overseas (Cayman Islands) Limited ("STOL"), and Promociones Telefonicas S.A.
    ("Protelsa").  Wireless Data Services, Ltd. ("WDS"), although 50% owned by
    the Company, has also been consolidated in the accompanying consolidated
    financial statements as the Company has the ability to exercise control
    over WDS.  All significant intercompany accounts and transactions have been
    eliminated in consolidation.

(4) INVESTMENTS IN AFFILIATES

    The Company's investments in affiliates represent interests in various LWBs
    in several developing countries. These investments are accounted for under
    the equity or cost methods of accounting.

    EQUITY INVESTMENTS

    For those investments in companies in which the Company's voting interest
    is 20% to 50%, or for investments in companies in which the Company exerts
    significant influence through board representation and management authority
    even if its ownership is less than 20%, the equity method of accounting is
    used. Under this method, the investment, originally recorded at cost, is
    adjusted to recognize the Company's share in losses of affiliates, limited
    to the extent of the Company's investment in and advances to affiliates,
    including any debt guarantees or other contractual funding commitments. All
    affiliated companies have fiscal years ended December 31.  Investments in
    affiliated companies are as follows as of December 31, 1996 and March 31,
    1997 (in thousands):

    COST INVESTMENTS

    The Company uses the cost method of accounting for three other investments
    as of March 31, 1997. These are PT Mobilkom Telekomindo ("Mobilkom"), RPG
    Paging Services Limited ("RPSL"), and Telecomunicaciones Globales, S.A. de
    C.V. ("Global Telecom").  The Company owns its holding in RPSL indirectly
    through its interest in STOL.  STOL purchased an additional 9% of RPSL in
    January 1997 for $2,100,000 which increased the Company's indirect interest
    from 7% to 13.3%.  The Company acquired its interest in Global Telecom, a
    Mexican long distance company in January 1997 for $62,000.  As of March 31,
    1997, the Company's ownership interests in these entities were 15%, 13.3%
    and 1.56%, respectively 

    The following represents the Company's carrying value of these cost
    investments:

    PRO FORMA SUMMARY

    The following unaudited pro forma summary combines the consolidated results
    of operations of the Company as if (i) TeamTalk had been a wholly owned
    consolidated subsidiary since January 1, 1996, (ii) ownership in RHP had
    been 28.3% since January 1, 1996, (iii) the acquisition of STOL had
    occurred on January 1, 1996, (iv) the acquisition of SDL had occurred at
    January 1, 1996 and (v) the acquisition of Protelsa had occurred at January
    1, 1996.  This pro forma summary does not necessarily reflect the results
    of operations as they would have been if the Company had acquired the
    entities as of January 1, 1996.

    Unaudited pro forma consolidated results of operations for the various
    acquisitions as described above are as follows (in thousands):

(5) NOTES RECEIVABLE FROM AFFILIATES

    In March 1997, the Company lent $3,500,000 to SDL.  The loan, which is

(8) COMMITMENTS AND CONTINGENCIES

    CAPITAL CONTRIBUTIONS

    In order to protect IWC's investments in affiliates from ownership
    dilution, IWC anticipates making additional capital contributions to the
    LWBs as needed.

    GUARANTEE OF DEBT OF EQUITY INVESTEE

    In connection with a Malaysian Ringgit 91,000,000 (approximately
    $36,694,000 as translated using effective exchange rates at March 31, 1997)
    senior credit facility through a syndicate of Malaysian banks obtained by
    the Company's 30% equity investee, STW, the Company along with other STW
    shareholders, executed a financial "keep well" covenant pursuant to which
    they have agreed (i) to ensure that STW will remain solvent and be able to
    meet its financial liabilities when due and (ii) to ensure that the project
    is completed in a timely manner and to make additional debt and equity
    investments in STW to meet cost overruns. The loan is repayable by STW in
    eleven semi-annual installments beginning October 8, 1997. The Company and
    other STW shareholders have separately executed an agreement, whereby each
    shareholder has agreed to share in the liability on a pro rata basis in
    relation to their interest in STW. In the event that the bank were to seek
    repayment from the STW shareholders and the other shareholders were unable
    to honor their pro rata share in the liability, the Company might be liable
    for the full amount of the outstanding amount of the loan. As of March 31,
    1997, this credit facility was fully drawn down. 

    The Company does not believe it is practicable to estimate the fair value
    of the guarantee and does not believe exposure to loss is likely.
    Accordingly, no provision has been made in the accompanying consolidated
    financial statements. 

    The Company, indirectly through its affiliate, New Zealand Wireless
    Limited, owns 15% of Mobilkom.  Mobilkom expects to fund the continued
    buildout of its network and the acquisition of subscriber terminals
    primarily through a seven-year $50 million revolving/reducing credit
    facility which it has obtained from a syndicate of Thai banks. Borrowings
    under the credit facility bear interest at a floating rate based on LIBOR
    and are secured by substantially all of Mobilkom's assets and a pledge of
    all the capital stock held by the Company and Mobilkom's other
    shareholders. Another Mobilkom shareholder has guaranteed borrowings of up
    to $25 million under the credit facility. As of March 31, 1997, borrowings
    of approximately $21,637,000 were outstanding under this facility. 

    The Company indirectly owns a 19.8% equity interest in PT Mobile Selular
    Indonesia ("Mobisel"), a provider of cellular services in Indonesia through
    its 28.3% ownership in RHP. Mobisel has obtained a six-year $60 million
    credit facility from Nissho Iwai International (Singapore) Pte. Ltd.
    ("Nissho Iwai") to finance the construction of its network. Borrowings
    under the credit facility bear interest at a floating rate based on LIBOR
    and are secured by all of Mobisel's assets and a pledge of all the capital
    stock held by RHP and Mobisel's other shareholders. RHP has also guaranteed
    the credit facility. As of March 31, 1997, this credit facility was fully
    drawn down.

(9) SUBSEQUENT EVENTS


    On May 5, 1997, the Board of Directors granted options to purchase an
    aggregate of 342,000 shares of Common Stock at an exercise price of $9.375
    per share to certain service providers of the Company.

    On May 5, 1997, the Company entered into an agreement with Vanguard
    Cellular Financial Corp. (together with its wholly owned subsidiary, 
    Vanguard Cellular Operating Corp., "Vanguard"), pursuant to which Vanguard
    surrendered then outstanding warrants to purchase 323,880 shares of Series
    C Preferred Stock, 416,720 shares of Series D Preferred Stock and 64,120
    shares of Series F Preferred Stock in exchange for the issuance by the
    Company of a warrant to acquire 249,970 shares of Common Stock at a
    purchase price of $0.25 per share and a second warrant to purchase 554,750
    shares of Common Stock at an exercise price of $9.375 per share, which
    second warrant was subsequently surrendered by Vanguard in exchange for the
    issuance to certain officers and employees of Vanguard of an option to
    purchase 53,330 shares of Common Stock at an exercise price of $9.375 

                                       13.

    per share under the 1996 SO/SIP and options to purchase an aggregate of 
    501,420 shares of Common Stock at a purchase price of $9.375 per share 
    outside the 1996 SO/SIP.  Such transaction and the issuance of such options 
    and warrants by the Company were approved by the Board of Directors of the
    Company on February 28, 1997, and by the stockholders of the Company on May
    5, 1997.

    On or prior to May 6, holders of warrants to purchase an aggregate of
    28,520 shares of Series D Preferred Stock exercised such warrants pursuant
    to the "net-exercise" provisions thereof.  Upon such exercises, such
    warrantholders received an aggregate of 8,552 shares of Series D Preferred
    Stock.

    The holders of the Warrants issued in connection with the Debt Offering 
    are entitled to purchase 11.638 shares of Common Stock per Warrant,
    representing in the aggregate approximately 10.0% of the outstanding stock
    of the Company on a fully-diluted basis as of August 15, 1996.  In the
    event that a qualified initial public offering of Common Stock in which the
    Company raises at least $50 million in net cash proceeds does not occur on
    or prior to May 15, 1997, each unexercised Warrant will entitle the holder
    thereof to purchase an additional 2.645 shares of Common Stock.  The
    Company does not expect to complete such an offering on or prior to May 15,
    1997.

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

     THE DISCUSSION IN THIS REPORT CONTAINS FORWARD-LOOKING STATEMENTS THAT 
INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS COULD DIFFER 
MATERIALLY FROM THOSE DISCUSSED HEREIN. FACTORS THAT COULD CAUSE OR 
CONTRIBUTE TO SUCH DIFFERENCES INCLUDE, BUT ARE NOT LIMITED TO, THOSE 
DISCUSSED IN "RISK FACTORS THAT MAY AFFECT FUTURE RESULTS" AS WELL AS THOSE 
DISCUSSED IN THIS SECTION AND ELSEWHERE IN THIS REPORT, AND THE RISKS 
DISCUSSED IN THE "RISK FACTORS" SECTION INCLUDED IN THE COMPANY'S ANNUAL 
REPORT ON FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 1996, FILED WITH THE 
SECURITIES AND EXCHANGE COMMISSION ON APRIL 15, 1997.

RESULTS OF OPERATIONS
    
     The Company's net loss increased from $3.6 million for the three month 
period ended March 31, 1996 to $14.5 million for the corresponding period in 
1997, an increase of 304%.  These increases were due primarily to higher 
selling, general and administrative expenses, increases in equity in losses 
of affiliates and an increase in interest expense, as more fully described 
below.

     The Company recorded no operating revenues and cost of revenues for the 
three month period ended March 31, 1996 compared to $519,000 in operating 
revenues, offset by $589,000 in cost of revenues, for the corresponding 
period in 1997. The operating revenues and cost of revenues for the three 
month period ended March 31, 1997 resulted from the acquisition, effective 
April 30, 1996, of the remaining 50% of TeamTalk, which increased the 
Company's equity interest in TeamTalk to 100% and resulted in the 
consolidation of TeamTalk's operations in the Company's financial statements.

     The Company's selling, general and administrative expenses increased 
from $2.3 million for the three month period ended March 31, 1996 to $6.3 
million for the corresponding period in 1997, an increase of 177%.  This 
increase was due primarily to continued growth both in the Company's own 
general and administrative expenses, including salaries and benefits expense, 
professional fees and all other general and administrative expenses, and in 
the selling, general and administrative expenses of its consolidated 
subsidiaries that have commenced operations, primarily TeamTalk and SRC.  The 
Company's selling, general and administrative expenses for such period also 
reflected the consolidated results of four other subsidiaries whose 
operations are currently in the developmental stage, all of which contributed 
to the overall increase in the selling, general and administrative expenses 
from the three month period ended March 31, 1996  as compared to the 
corresponding period in 1997. 

     The primary components of the Company's selling, general and 
administrative expenses include (i) overall growth in the Company's own 
general and administrative expenses, including an increase in salaries and 
benefits from $819,000 for the three month period ended March 31, 1996 to 
$1.2 million for the corresponding period in 1997, an increase in 
professional fees from $565,000 for the three month period ended March 31, 
1996 to $638,000 for the corresponding period in 1997 and an increase in all 
other general and administrative expenses from $481,000 for the three month 
period ended March 31, 1996 to $849,000 for the corresponding period in 1997; 
and (ii) selling, general and administrative expenses of $617,000 and $2.0 
million for the three month period ended March 31, 1997 associated with the 
consolidation of the operations of TeamTalk and SRC, respectively, in the 
Company's consolidated financial statements as compared to $229,000 of 
selling, general and administrative expenses associated with the 
consolidation of the operations of SRC for the corresponding period in 1996.  
In addition, the Company reflected selling, general and administrative 
expenses of four other subsidiaries whose operations are currently in the 
developmental stage for the three month period ended March 31, 1997 with a 
resultant increase of $751,000 as compared to the corresponding period in 
1996. 

     The Company's equity in losses of affiliates increased from $1.4 million 
for the three month period ended March 31, 1996 to $4.7 million for the 
corresponding period in 1997, an increase of 229%.  For the three month 
period ended March 31, 1996, the equity in losses of affiliates was 
attributable to $899,000 of  operating losses and 

                                       15.

$520,000 of expense relating to the amortization of telecommunication 
licenses.  For the corresponding period in 1997, equity in losses of 
affiliates consisted of $3.8 million of operating losses and $843,000 of 
expense relating to amortization of telecommunication licenses.  The increase 
in the equity in losses of affiliates is attributable primarily to the 
increase in the underlying operating losses of RHP, SDL and STW.  

     The Company's equity in losses of affiliate attributable to RHP 
increased from $78,000 for the three month period ended March 31, 1996 to 
$1.3 million for the corresponding period in 1997 as RHP's 70% owned 
consolidated subsidiary, Mobisel, continued to expand its operations and 
roll-out its nationwide telecommunication network. During this expansion 
phase, Mobisel's gross profit declined due primarily to greater pulse sharing 
and airtime costs and an increase in depreciation expense due to the 
build-out of Mobisel's telecommunication network.  In addition, as part of 
its expansion effort, Mobisel experienced growth in its selling, general and 
administrative expense base in order to meet the anticipated growth in its 
operations. The Company's amortization of telecommunication license 
attributable to RHP increased from $296,000 for the three month period ended 
March 31, 1996 to $419,000 for the corresponding period in 1997, an increase 
of 42%, due to the Company's additional investment of $8.6 million in RHP 
during October 1996.

     The Company's equity in losses of affiliates attributable to its 40% 
interest in SDL, which the Company acquired in November 1996, was $1.7 
million for the three month period ended March 31, 1997; and the Company's 
amortization of telecommunication license attributable to SDL was $191,000 
for the three month period ended March 31, 1997.  SDL operating losses are 
anticipated to increase throughout the foreseeable future as SDL continues to 
expand its operations within the Peoples Republic of China.  

     The Company's equity in losses of affiliate attributable to STW 
increased from $546,000 for the three month period ended March 31, 1996 to 
$708,000 for the corresponding period in 1997, an increase of 30%, and the 
Company's amortization of telecommunication license attributable to STW 
increased from $218,000 for the three month period ended March 31, 1996 to 
$221,000 for the corresponding period in 1997.

     The Company's interest income increased from $242,000 for the three 
month period ended March 31, 1996 to $527,000 for the corresponding period in 
1997, an increase of 118%.  This increase was due primarily to interest 
earned on the proceeds from the Debt Offering in August 1996, which were 
invested in short-term interest-bearing securities. 

     The Company's interest expense increased from $119,000 for the three 
month period ended March 31, 1996 to $4.2 million for the corresponding 
period in 1997. The increase in interest expense was primarily due to 
interest expense associated with the Debt Offering.

IMPACT OF INFLATION AND CURRENCY FLUCTUATION

     Many developing countries have experienced substantial, and in some 
periods extremely high, rates of inflation and resulting high interest rates 
for many years.  Inflation and rapid fluctuations in inflation rates have had 
and may continue to have negative effects on the economies and securities 
markets of certain developing countries and could have an adverse effect on 
the operating companies and developmental stage projects in those countries, 
including an adverse effect on their ability to obtain financing.

     The value of the Company's investment in an operating company or 
developmental stage project is partially a function of the currency exchange 
rate between the dollar and the applicable local currency.  In addition, the 
operating companies will report their results of operations in the local 
currency and, accordingly, the Company's results of operations will be 
affected by changes in currency exchange rates between those currencies and 
U.S. dollars.  The Company does not hedge against foreign currency exchange 
rate risks.  As a result, the Company may experience economic loss with 
respect to its investments and fluctuations in its results of operations 
solely as a result of currency exchange rate fluctuations.  For example, the 
Company experienced a significant decline in the value of its investment in 
Mobilcom Mexico, its ECTR operating company in Mexico, as a result of the 
1994 devaluation of the Mexican peso and the resulting economic instability 
in Mexico.  Many of the currencies of developing countries have experienced 
steady devaluations relative to the U.S. dollar, and major adjustments have 
been made in the past and may again occur in the future, any of which could 
have a material adverse effect on the Company.

                                       16.

<PAGE>

     To the extent that the operating companies commence or have commenced 
commercial operations, any revenues they generate will generally be paid to 
the operating companies in the local currency.  By contrast, many significant 
liabilities of the operating companies (such as liabilities for the financing 
of telecommunications equipment) may be payable in U.S.  dollars or in 
currencies other than the local currency.  As a result, any devaluation in 
the local currency relative to the currencies in which such liabilities are 
payable could have a material adverse effect on the Company.

LIQUIDITY AND CAPITAL RESOURCES
    
     To date, the Company has funded its cash requirements primarily through 
the use of the net proceeds of a series of Preferred Stock private 
placements, bridge loans and the Debt Offering. The bridge loans have 
generally been converted into Preferred Stock. The proceeds from these 
financings were mainly used to fund the Company's investments in operating 
companies and developmental stage projects, to provide working capital and 
for general corporate purposes, including the expenses incurred in seeking 
and evaluating new investment opportunities. As of March 31, 1996 and March 
31, 1997, the Company had cash and cash equivalents and short-term investment 
balances of $15.6 million and $27.3 million, respectively.

     The Company has generated negative cash flow from operations since 
inception, and its operating companies and developmental stage projects are 
not expected to provide any cash to the Company in the foreseeable future. As 
a result, the Company is and will remain dependent upon raising funds from 
outside sources to fund its working capital needs, investments in operating 
companies and developmental stage projects, other cash requirements and to 
repay the Notes and any other indebtedness it may incur when it becomes due 
and payable.

     The Company believes its existing cash balance is sufficient to meet its 
minimum operating and contractual obligations through the end of fiscal 1997. 
However, the Company will require additional financing prior to December 31, 
1997, to meet its business objective of participating in additional equity 
rounds of financing on the operating company and developmental stage project 
level in order to finance the expansion of the operations of such operating 
companies and developmental stage projects. The Company has neither received 
commitments nor completed arrangements for additional financing, and there 
can be no assurance that additional financing will be available to the 
Company on acceptable terms when required by the Company or at all. The 
Company's inability to obtain such additional financing on acceptable terms 
would have a material adverse effect on the Company. In addition, the Company 
intends to pursue additional investment opportunities for wireless 
communications projects and will require additional sources of financing in 
order to pursue those investments. However, there can be no assurance that 
such additional financing will be available on favorable terms or at all. See 
"--Additional Factors That May Affect Future Results--Company Level 
Risks--Negative Operating Cash Flow; Dependence on Additional Financing; No 
Commitments for Additional Financing."
    
     At the project level, IWC and its partners typically fund initial 
project investments using capital contributions either in the form of equity 
or shareholder loans. When projects become operational, IWC seeks to fund 
ongoing development of the project using third-party financing, preferably on 
a non-recourse basis to the Company.

     Mobilkom, IWC's national ECTR operating company in Indonesia, arranged a 
$50.0 million credit facility through a syndicate of Thai banks. This 
facility is secured by all of the assets and capital stock of Mobilkom, and 
$25.0 million of the facility has been guaranteed by Jasmine International 
Public Company Limited ("Jasmine"), a 56.25% owner of Mobilkom. As of March 
31, 1997, approximately $21.6 million was outstanding under this facility. 
The Company anticipates that the current $50.0 million facility will be 
sufficient for Mobilkom to meet all of its currently anticipated expenditures 
through 1997. Borrowings outstanding under this credit facility must be 
repaid in 16 quarterly installments commencing in 2000.

     Mobisel, IWC's national cellular operating company in Indonesia, in 
which the Company held an indirect 19.8% interest as of March 31, 1997 
through IWC's investment in RHP, has obtained a $60.0 million credit facility 
from Nissho Iwai.  This facility is secured by all of Mobisel's assets and a 
pledge of all of the capital stock of Mobisel held by RHP, which has also 
guaranteed the credit facility. The use of borrowings under the credit 
facility with Nissho Iwai is limited to expenditures necessary for the 
implementation and construction of Mobisel's network. Mobisel will require 
substantial additional financing to complete its planned capital expenditures 
through 1997 and 

                                       17.

<PAGE>

for other purposes. Accordingly, Mobisel has commenced discussions with a 
number of potential financing sources in order to obtain additional 
financing. Borrowings outstanding under this credit facility must be repaid 
in six equal semi-annual installments beginning in late 1998.

     STW, IWC's national WLL operating company in Malaysia, has arranged a 
Malaysian Ringgit 91.0 million (approximately $36.7 million as of March 31, 
1997) credit facility through a syndicate of Malaysian banks. This facility 
is secured by substantially all of STW's assets and a pledge of all of the 
capital stock of STW held by IWC and STW's other shareholders, and has been 
guaranteed by Shubila Holding Sdn Bhd, the 60% owner of STW, and certain 
officers of STW (including a former officer of IWC). In addition, STW has 
agreed to assign to and deposit with the banks all of its cash, including 
revenues, loan drawings and shareholder advances. In addition to pledging 
their capital stock in STW, IWC and the other STW shareholders have entered 
into a "keep well" covenant pursuant to which they have agreed (i) to insure 
that STW remains solvent and able to meet its financial liabilities when due, 
and (ii) to insure the timely completion of its WLL project and to make 
additional debt or equity investments in STW necessary to meet any cost 
overruns. The Company and other STW shareholders have also separately 
executed an agreement, whereby each shareholder has agreed to share in the 
liability on a pro rata basis in relation to their interest in STW. In the 
event that the banks were to seek repayment from the STW shareholders and the 
other shareholders were unable to honor their pro rata share of the 
liability, the Company might be liable for the full amount of the outstanding 
amount of the loan. Borrowings outstanding under this credit facility must be 
repaid in eleven semi-annual installments beginning October 8, 1997.

ADDITIONAL FACTORS THAT MAY AFFECT FUTURE RESULTS

     THE COMPANY OPERATES IN A RAPIDLY CHANGING ENVIRONMENT THAT INVOLVES A 
NUMBER OF RISKS, SOME OF WHICH ARE BEYOND THE COMPANY'S CONTROL.  THE 
FOLLOWING DISCUSSION HIGHLIGHTS SOME OF THESE RISKS.  THESE RISKS SHOULD BE 
READ IN CONJUNCTION WITH THE "RISK FACTORS" SECTION INCLUDED IN THE COMPANY'S 
REGISTRATION STATEMENT ON FORM S-1 AS FILED WITH THE COMMISSION ON FEBRUARY 
12, 1997, AS SUBSEQUENTLY AMENDED (REG. NO. 333-21687).

COMPANY LEVEL RISKS

CONTINUING LOSSES; LIMITED OPERATING HISTORY 

The Company has incurred net losses since its inception and had an accumulated
stockholders' deficit of approximately $68.4 million as of March 31, 1997. The
Company anticipates that its net losses will increase significantly in the
foreseeable future, and there can be no assurance as to whether or when the
Company's operations will become profitable. See "--Results of Operations."  The
Company has a limited operating history. Since its inception in January 1992,
the Company's activities have been concentrated primarily in the early stage
development of its wireless projects, including the selection of local partners,
the formation of operating companies and the pursuit of operating licenses. 

NEGATIVE OPERATING CASH FLOW; DEPENDENCE ON ADDITIONAL FINANCING; NO COMMITMENTS
FOR ADDITIONAL FINANCING

     The Company used cash in operations and investing activities of $73.2 
million for the year ended December 31, 1996, and $17.4 million for the 
three-months ended March 31, 1997, and expects such negative cash flows to 
continue and likely increase in the foreseeable future. Because of such 
negative cash flow and negative working capital and the capital intensive 
nature of the Company's business, the Company will require continuing sources 
of outside debt and equity financing to fund its working capital needs, 
investments and other cash requirements. 

     In particular, the Company will require additional financing prior to 
December 31, 1997, to meet currently anticipated requirements for working 
capital and investments in its operating companies and developmental stage 
projects. In addition, the Company intends to pursue additional investment 
opportunities for wireless projects and anticipates that it will require 
additional sources of financing in order to fund those investments. However, 
the Company has neither received commitments nor completed arrangements for 
additional financing, and there can be no assurance that any additional debt 
or equity financing will be available to the Company on acceptable terms when 
required by the 

                                       18.

<PAGE>

Company or at all. If adequate sources of additional financing are not 
available, the Company may be forced (i) to delay, scale back or eliminate 
one or more of its projects, (ii) to suffer a significant dilution of its 
equity interest or loss of value in one or more of its investments, or (iii) 
to liquidate one or more of its investments.  In addition, the Company may be 
unable to repay its liabilities (including the Notes) as they become due, and 
may be unable to meet its working capital and other cash requirements. The 
Indenture contains certain restrictions on the ability of the Company to make 
investments in, or guarantee the indebtedness of, the operating companies and 
developmental stage projects. Accordingly, the Company's inability to obtain 
such additional financing would have a material adverse effect on the Company 
and could result in its insolvency or liquidation. 

SUBSTANTIAL LEVERAGE

     The Company is highly leveraged and has indebtedness that is substantial 
in relation to its stockholders' equity, including its redeemable convertible 
Preferred Stock. As of March 31, 1997, the Company's long term debt was $79.4 
million, and its stockholders' deficit and redeemable convertible Preferred 
Stock was $66.1 million. The high level of the Company's indebtedness will 
have important consequences, including (i) limitations on the Company's 
ability to obtain additional debt financing in the future and (ii) 
limitations on the Company's flexibility in reacting to changes in the 
industry and economic conditions generally.  In addition, most of the 
existing operating companies and developmental stage projects will not be 
subject to any limitations restricting the incurrence of additional 
indebtedness, and, to the extent that the Company is successful in its 
strategy of obtaining additional financing at the operating company or 
developmental stage project level, the amount of such indebtedness could 
increase substantially, which may have consequences similar to those 
described in clauses (i) and (ii) above with respect to the Company. 

RISK OF INABILITY TO REPAY NOTES AT MATURITY

     The Company has had net losses and has generated negative cash flow from 
operations since inception.  Further, as discussed below under "}-Holding 
Company Structure; Limitations on Access to Cash Flow of Operating 
Companies," the Company does not expect that it will generate positive cash 
flow through dividends or other distributions from its operating companies 
for the foreseeable future. Accordingly, the Company's ability to repay the 
Notes and any other indebtedness which it may incur from time to time at 
maturity will be dependent on developing one or more sources of financing 
prior to the maturity of such indebtedness. The Company may, among other 
things, (i) seek to refinance all or a portion of such indebtedness at 
maturity through sales of additional debt or equity securities of the Company 
or other borrowings, (ii) seek to sell all or a portion of its interests in 
one or more of its operating companies or developmental stage projects 
(subject to the restrictions described below under "--Company Level 
Risks--Restrictions on Transfer of Ownership Interests") or (iii) negotiate 
with its financial and strategic partners to permit the cash, if any, 
produced by the operating companies to be distributed to equity holders. 
There can be no assurance that (i) the Company will be able to obtain debt or 
equity refinancing on acceptable terms, or at all, in the future, (ii) the 
Company will be able to sell assets in a timely manner or on commercially 
acceptable terms or in an amount that will be sufficient to repay its 
indebtedness when due, (iii) the Company will be able to obtain the consents 
and approvals required in order to sell its interests in, or to receive 
dividends from, its operating companies or developmental stage projects or 
(iv) that the operating companies or developmental stage projects will in 
fact generate positive cash flow or that any such cash flow will be 
distributed to equity holders (particularly since the Company expects that 
its operating companies will generally reinvest all of their cash flow in 
development opportunities for the foreseeable future). In addition, a default 
under the Notes or such other indebtedness as the Company may incur in the 
future, for example, could in turn permit lenders under STW's Malaysian 
Ringgit 91 million (approximately $36,694,000 as translated using effective 
exchange rates at March 31, 1997) senior credit facility, and possibly under 
other debt instruments of the operating companies, to declare borrowings 
outstanding thereunder to be due and payable pursuant to cross-default 
clauses, permitting the lenders under such debt instruments to proceed 
against any collateral pledged as security therefor. Any failure by the 
Company to repay the Notes when due would have a material adverse effect on 
the Company.

RISK OF GOVERNMENTAL ACTIONS RESULTING IN VIOLATION OF INDENTURE

     The Indenture pursuant to which the Notes were issued, contains 
covenants that impose certain requirements with respect to sales or other 
dispositions of assets with a fair market value in excess of $500,000 
(including capital stock in operating companies and in developmental stage 
projects) by the Company and certain subsidiaries of the Company ("Asset 
Sales"). Among other things, the Indenture requires that at least 85% of the 
consideration for an Asset 

                                       19.

<PAGE>

Sale be in cash and that the Company receive consideration equal to the fair 
market value of the assets in question. However, if an Asset Sale occurs 
because of governmental action (for example, by expropriation or 
confiscation), or in certain other circumstances including, among other 
things, a sale of the Company's investment in certain operating companies 
compelled by other stockholders of such operating company or pursuant to 
rights granted to certain bank lenders of certain operating companies, the 
requirement that the Company receive fair market value for the assets shall 
be deemed to have been satisfied to the extent that the difference between 
the fair market value of such assets and the actual consideration received in 
such Asset Sale (and all other Asset Sales subject to this exception) is less 
than 10% of the "total market value of equity" of the Company. However, if an 
Asset Sale is compelled by governmental action, the Indenture still requires 
that at least 85% of the consideration be in cash. 

     In certain of the countries in which the Company has made investments, 
there is a risk that the Company's investments may be confiscated or 
expropriated by governmental authorities. In particular, in early 1996, the 
Malaysian government initiated efforts to consolidate the Malaysian 
telecommunications industry, which, if completed would have forced a sale or 
merger of STW, the Company's Malaysian operating company, to or with one of a 
limited number of surviving telecommunications companies. There can be no 
assurance that the Malaysian government will not seek to take similar actions 
in the future. Likewise, other countries may seek to expropriate or 
confiscate assets of the Company. To the extent that the consideration, if 
any, received by the Company in connection with these expropriations or 
confiscations failed to satisfy the covenants under the Indenture, such a 
violation will be deemed an event of default under the Indenture entitling 
the holders of the Notes to demand immediate repayment thereof and to proceed 
against their collateral, which would have a material adverse effect on the 
Company. See "--Project Level Risks--Risks Inherent in Foreign Investment." 

HOLDING COMPANY STRUCTURE; LIMITATIONS ON ACCESS TO CASH FLOW OF OPERATING
COMPANIES

     The Company is a holding company with no business operations of its own. 
All of the operations of the Company are conducted through its wholly owned 
subsidiary, IWC, and its affiliated companies, which are separate and 
distinct legal entities and have no obligation, contingent or otherwise to 
make any funds available to the Company to enable it to make investments in 
operating companies or developmental stage projects, meet working capital 
needs or other liabilities of the Company (including liabilities under the 
Notes), or for any other reason. In addition, most of the operating companies 
have generated negative cash flow from operations, and the Company expects 
that most operating companies will continue to generate negative cash flow 
from operations for the foreseeable future. Further, to the extent that any 
of the operating companies generates positive cash flow, the Company may be 
unable to access such cash flow because (i) it owns 50% or less of the equity 
of most of such entities and, therefore, does not have the requisite control 
to cause such entities to pay dividends to their equity holders; (ii) certain 
of such entities are currently or may become parties to credit or other 
borrowing agreements that restrict or prohibit the payment of dividends, and 
such entities are likely to continue to be subject to such restrictions and 
prohibitions for the foreseeable future; (iii) the Company expects that its 
operating companies will generally reinvest all of their cash flow in 
development opportunities for the foreseeable future; and/or (iv) some of the 
countries in which such entities conduct business, tax the payment and 
repatriation of dividends or otherwise restrict the repatriation of funds. As 
a result, the Company does not expect that it will be able to generate any 
significant cash flow through dividends or other distributions from the 
operating companies in the foreseeable future, and there can be no assurance 
that the Company will be able to generate any significant cash flow from the 
operating companies at any time in the future. 

RESTRICTIONS ON TRANSFER OF OWNERSHIP INTERESTS

    The Company's ability to sell or transfer its ownership interests in its
operating companies and developmental stage projects is generally subject to (i)
limitations contained in the agreements between the Company and its local
partners including, in certain cases, complete prohibitions on sales or
transfers for a period of years, co-sale rights and/or rights of first refusal
and (ii) provisions in local operating licenses and local governmental
regulations that, in certain cases, prohibit or restrict the transfer of the
Company's ownership interests in such operating companies and developmental
stage projects. Moreover, the Company and its local partners have in the past
been required to pledge their capital stock in certain operating companies to
secure credit facilities obtained by those operating companies, and the Company
may be prohibited from transferring or otherwise disposing of such capital stock
so long as it is pledged as collateral for those credit facilities. In addition,
none of the operating companies or developmental stage projects currently has
any publicly traded securities and there can be no assurance that in the future
there will be either a public 

                                       20.

<PAGE>

or private market for the securities of the Company's operating companies or 
developmental stage projects. As a result, the Company's ability to liquidate 
any or all of its investments may be substantially limited and there can be 
no assurance that the Company will be able to do so in a timely manner, or at 
all in the event that the Company is required to do so in order to satisfy 
its cash needs, including providing funds for investments and repayment of 
indebtedness. Moreover, even if any sales are completed, the prices realized 
on those sales could be less than the Company's investment, and there may be 
substantial local taxes imposed on the Company in the case of any such sales 
and, in any event, there can be no assurance that there will not be 
substantial taxes or other restrictions on the ability of the Company to 
repatriate any amounts realized upon the sale of any such investments. In 
addition, certain of the operating companies and developmental stage projects 
are or may be parties to credit agreements that restrict their ability to pay 
dividends or make other distributions to their equity investors, and the 
Company's local partners, by virtue of their majority ownership interest in 
the operating companies and developmental stage projects, generally have the 
right to determine the timing and amount of any such dividends or 
distributions. 

LACK OF CONTROL OF OPERATING COMPANIES AND DEVELOPMENTAL STAGE PROJECTS

     The Company anticipates that it will often have a minority interest in 
its operating companies and developmental stage projects, in part because 
applicable laws often limit foreign investors to minority equity positions. 
Although the Company is actively involved in the management of most of the 
operating companies and developmental stage projects in which it has an 
ownership interest and intends to invest in the future in operating companies 
and developmental stage projects in which it can participate in management, 
its minority voting positions may preclude it from controlling such entities 
and implementing strategies that it favors, including strategies involving 
the expansion or development of projects or the pursuit of certain financing 
alternatives. Moreover, even where the Company has majority control of a 
project, the exercise of such control may be subject to contractual, 
regulatory or other restrictions. In addition, the Company may be unable to 
access the cash flow, if any, of its operating companies. See "--Company 
Level Risks--Holding Company Structure; Limitations on Access to Cash Flow of 
Operating Companies." 

RISKS INHERENT IN GROWTH STRATEGY

     The Company has grown rapidly since inception, and as of March 31, 1997, 
had operating companies or developmental stage projects in 13 foreign 
countries. Subject to the availability of additional financing, the Company 
anticipates that it will make additional investments in wireless projects in 
other foreign countries and is actively seeking and evaluating new investment 
opportunities in foreign countries where it currently has operating companies 
or developmental stage projects. This strategy presents the risks inherent in 
assessing the value, strengths and weaknesses of development opportunities, 
in evaluating the costs and uncertain returns of building and expanding the 
facilities for operating systems and in integrating and managing the 
operations of additional operating systems. The Company's growth strategy 
will place significant demands on the Company's operational, financial and 
marketing resources and on its management. Any failure to manage the Company 
effectively could have a material adverse effect on the Company. 

RISK OF REGISTRATION UNDER INVESTMENT COMPANY ACT OF 1940

     Because the Company often acquires minority ownership positions in 
operating companies and development stage projects, there is a risk that 
these ownership positions could be deemed to be investment securities and 
that the Company could be characterized as an investment company under the 
Investment Company Act of 1940 (the "Investment Company Act"). Due to the 
Company's active role in developing and managing the operating companies and 
its contractual rights as an equity holder, the Company believes that a 
substantial majority of its interests in the operating companies are the 
equivalent of joint venture interests rather than investment securities. 
Therefore, the Company believes that it is not an investment company and 
intends to continue its business and conduct its operations so as not to 
become subject to the Investment Company Act. If the Commission or its staff 
were to take the position, or if it were otherwise asserted, that the Company 
is an investment company, the Company could be required either (i) to 
liquidate its investments in one or more operating companies or developmental 
stage projects and change the manner in which it conducts its operations to 
avoid being required to register as an investment company or (ii) to register 
as an investment company. If the Company were required to register under the 
Investment Company Act, it would be subject to substantive regulations with 
respect to capital structure, operations, transactions with affiliates and 
other matters. In addition, a determination that the Company is subject to 
the Investment Company Act would constitute an event of default under the 
Indenture and permit acceleration of the Notes. If the Company were found to 
be an investment 

                                       21.

company but was not registered under the Investment Company Act, the Company 
would be prohibited from, among other things, conducting public offerings in 
the U.S. or engaging in interstate commerce in the U.S., the Company would be 
subject to monetary penalties and injunctive relief in an action brought by 
the Commission, and certain contracts to which the Company is a party 
(including the Indenture and the Notes) might be rendered unenforceable or 
subject to rescission by any party thereto. As a result, any determination 
that the Company is an investment company would have a material adverse 
effect on the Company and would likely require that the Company cease 
operations.

CONTROL OF THE COMPANY

     At March 31, 1997, Vanguard beneficially owned approximately 39% of the 
Company's equity, without giving effect to the warrant and option exchange 
transaction described in Note 9 of the Notes to Consolidated Financial 
Statements above. Vanguard has provided and continues to provide a number of 
services to the Company relating to the formation, development and operation 
of wireless communications services, including identification and evaluation 
of wireless communications opportunities, review of business and technical 
plans and assistance in training operating company personnel. Vanguard has 
the right to elect three directors to the Company's Board of Directors and 
currently has three representatives on such Board, including Haynes G. 
Griffin, Chairman of the Board of Directors. As a result, Vanguard may have 
the ability to effectively control the Company and direct its business and 
affairs. 

CONFLICTS OF INTEREST

     Vanguard is not precluded from competing with the Company by itself or 
through affiliates by developing, owning and/or operating international 
wireless communications businesses, including businesses that use the same or 
similar technologies or provide the same services as the Company's existing 
and future operating companies. This is true even though the Company acquired 
substantially all of Vanguard's interests in certain of its international 
wireless projects in December 1995. Further, although many of the agreements 
governing the relationship between the Company and its local partners contain 
preemptive rights, rights of first refusal and/or rights of co-sale with 
respect to the sale of shares in the Company's joint ventures, Vanguard is 
not precluded from co-investing with the Company in such joint ventures. For 
example, in April 1997, Vanguard purchased a 7% equity interest in SDL 
directly from STHL, the Company's local partner in SDL. Although the 
directors designated by Vanguard may abstain from voting on matters in which 
the interests of the Company and Vanguard are in conflict, they are not 
obligated to do so, and the Company has not adopted any formal policies or 
procedures designed to prevent actual conflicts of interest from occurring. 
As a result, the presence of potential or actual conflicts could affect the 
process or outcome of Board deliberations. There can be no assurance that 
such conflicts of interest will not materially adversely affect the Company. 
 
INFORMATION RELATING TO DEMOGRAPHIC, ECONOMIC, MARKET AND RELATED INFORMATION

     The information contained herein includes certain demographic and 
economic information, as well as information regarding cellular service, 
installation and penetration in the countries in which the Company has 
operating companies or developmental stage projects. This information was 
obtained from a number of sources and the Company has not independently 
verified any such information and there can be no assurance as to its 
accuracy. In addition, much of the information related to POPs are estimates 
and reflect data that may be incorrect or imprecise and such estimates and 
data have been obtained from a number of sources and the Company has not 
independently verified any such information. 

DEPENDENCE ON KEY PERSONNEL

     The success of the Company and its growth strategy depends in large part 
on the ability of the Company to attract and retain key management, marketing 
and operating personnel at each of the Company, operating company and 
developmental stage project levels. There can be no assurance the Company 
will be able to attract and retain the qualified personnel needed for its 
business, particularly because of the amount of international travel required 
of the Company's managers and because experienced local managers are often 
unavailable. In addition, the loss of the services of one or more members of 
its senior management team, particularly John D. Lockton or Hugh B. L. 
McClung, could have a material adverse effect on the Company. 

                                       22.

<PAGE>

CLASSIFICATION OF NOTES AS DEBT; ORIGINAL ISSUE DISCOUNT

     Although the Company intends to treat the Notes as debt for all 
purposes, there can be no assurance that the Internal Revenue Service will 
agree that the Notes qualify as debt for federal income tax purposes. If the 
Notes are not respected as debt for such purposes, they would likely be 
recharacterized as an equity interest in the Company and the interest that 
accretes on the Notes would not be deductible by the Company when accrued or 
paid. Loss of such interest deductions would increase income taxes ultimately 
payable by the Company, and thus, reduce cash flow otherwise available to 
repay the Notes, which would have a material adverse effect on the Company. 
Recharacterization of the Notes as equity could also adversely affect 
non-corporate holders as well as non-United States holders of the Notes. 

     Assuming the Notes are respected as debt for federal income tax 
purposes, they will be subject to the original issue discount provisions of 
the Code because they will have been issued at a non-de minimis discount from 
their principal amount. Consequently, the holders of the Notes generally will 
be required to include amounts in gross income for federal income tax 
purposes in advance of receipt of the cash payments to which the income is 
attributable. 

     If a bankruptcy case is commenced by or against the Company under the 
United States Bankruptcy Code after the issuance of the Notes, the claim of a 
holder of any of the Notes with respect to the principal amount thereof may 
be limited to an amount equal to the sum of (i) the initial offering price 
allocable to the Notes and (ii) that portion of the original issued discount 
which is not deemed to constitute "unmatured interest" for purposes of the 
Bankruptcy Code. Any original issued discount that was not amortized as of 
any such bankruptcy filing would constitute "unmatured interest." 

REPORTING STANDARDS; FINANCIAL STATEMENTS OF OPERATING COMPANIES; TIMELY
COMPLIANCE WITH INFORMATIONAL AND FILING REQUIREMENTS

     Companies in developing countries are subject to accounting, auditing 
and financial standards and requirements that differ, in some cases 
significantly, from those applicable to U.S. companies. In addition, there 
may be substantially less publicly available information about companies in a 
developing country than there is about U.S. companies. The Company's ability 
to comply with the informational and filing requirements of the Indenture and 
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), to 
which it is or will be subject will depend on the timely receipt of accurate 
and complete financial and other information from the Company's operating 
companies and developmental stage projects. The failure to receive such 
information on a timely basis could have a material adverse effect on the 
Company, including preventing it from satisfying the informational and filing 
requirements of the Indenture and the Exchange Act. 

RISK OF INABILITY TO FINANCE A CHANGE OF CONTROL OFFER

     Upon the occurrence of a Change of Control (as defined in the Indenture 
to include (i) a sale or transfer by the Company or a Restricted Subsidiary 
(as defined in the Indenture) of all or substantially all of its assets; (ii) 
the adoption of a plan of liquidation; (iii) the acquisition of greater than 
50% of the voting power by an entity other than Vanguard or (iv) upon the 
change of a majority of the Board of Directors), the Company will be required 
to make an offer to purchase all of the outstanding Notes at the price set 
forth in the Indenture. The Company's failure to purchase the Notes would 
result in a default under the Indenture. In the event of a Change of Control, 
there can be no assurance that the Company would have sufficient assets to 
satisfy all of its obligations under the Indenture. Future debt of the 
Company may also contain prohibitions of certain events or transactions which 
would constitute a Change of Control or require the obligations thereunder to 
be retired upon a Change of Control. 

NO CASH DIVIDENDS ON COMMON STOCK

     The Company is prohibited under the terms of the Indenture from paying 
dividends or making other distributions with respect to the Company's capital 
stock, including the Common Stock while the Notes are outstanding. The 
Company anticipates that all earnings, if any, will be retained for the 
operation and expansion of the Company's business. 

                                       23.

PROJECT LEVEL RISKS

OPERATING LOSSES AND NEGATIVE CASH FLOW; DEPENDENCE ON ADDITIONAL
FINANCING/CAPITAL

     Most of the operating companies have generated operating losses and 
negative cash flow from operations, and the Company expects that most of its 
operating companies will continue to generate operating losses and negative 
cash flow from operations for the foreseeable future. The business of the 
operating companies and developmental stage projects, particularly WLL 
projects, is capital intensive and, in light of such anticipated negative 
cash flow from operations, will require continuing sources of outside 
financing to fund working capital needs, capital expenditures and other cash 
requirements. The Company's strategy is to seek such additional financing at 
the operating companies primarily from third parties and not from the Company 
or its partners. However, there can be no assurance that the operating 
companies and developmental stage projects will be able to obtain the 
financing required to make planned capital expenditures, provide working 
capital or meet other cash needs. Failure to obtain such financing could have 
a material adverse effect on the Company and, among other things, could 
result in the loss or revocation of licenses held by the operating companies 
or developmental stage projects or require that certain planned projects be 
delayed or abandoned. In particular, at March 31, 1997 a significant portion 
of the Company's investments had been made in three operating companies 
(namely STW, which is developing a national WLL system in Malaysia; Mobisel, 
which is developing a national cellular system in Indonesia; and SDL, which 
is developing various regional cellular systems in China), and each of these 
operating companies will be required to obtain substantial additional 
financing in order to complete planned capital expenditures. 

     In most cases, under agreements with its local partners, the Company and 
its partners may be required to make additional equity investments in 
operating companies or developmental stage projects, and the Company's or 
such partners' inability or unwillingness to do so could result in the 
dilution of such party's equity interest or a significant impairment or loss 
of the value of the Company's investment. Moreover, the Company and its other 
strategic partners have in the past been required, and in the future likely 
will be required, to guarantee and/or pledge their respective equity 
interests to secure certain indebtedness of the operating companies and 
developmental stage projects and otherwise to provide certain assurances to 
lenders. See "--Liquidity and Capital Resources." The Indenture contains 
certain restrictions on the ability of the Company to make investments in, or 
guarantee the indebtedness of, the operating companies and developmental 
stage projects. 

     In addition, there can be no assurance that the operating companies or 
developmental stage projects will be able to pay their indebtedness or other 
liabilities when due. Any failure to pay such indebtedness or other 
liabilities when due could have a material adverse effect on the Company. See 
"--Company Level Risks--Negative Operating Cash Flow; Dependence on 
Additional Financing; No Commitments For Additional Financing" below. 

     To date, most of the debt financing obtained by the operating companies 
has been secured by assets of the respective operating companies, and it is 
likely that any debt financing the operating companies or developmental stage 
projects obtain in the foreseeable future will also be similarly secured. The 
pledge of assets to secure debt financing may limit the operations of the 
operating companies and make it substantially more difficult to obtain 
additional financing from other sources. 

EARLY STAGE OF DEVELOPMENT OF WIRELESS PROJECTS

     Most of the Company's wireless projects are in the early stages of 
development. Only the nine operating companies, Via 1, SDL, RPSL, Mobisel, 
Mobilkom, STW, Mobilcom Mexico, TeamTalk and UTS, currently provide wireless 
communications services on a commercial basis, and many of these operating 
companies have only recently initiated such commercial service and have a 
limited number of subscribers. Although MOUs have been signed with local 
partners in the operating companies and developmental stage projects, in many 
cases definitive joint venture and shareholder agreements have not been 
prepared or signed, definitive legal entities have not been formed and/or 
required equity and debt financing has not been secured. Even where an MOU or 
definitive joint venture or shareholder agreement has been signed, there can 
be no assurance that the terms of the Company's participation in an operating 
company or developmental stage project will not be modified in a manner that 
is materially adverse to the Company, particularly because the Company 
usually holds a minority interest. The successful development and 
commercialization of these projects will depend on a number of significant 
financial, logistical, technical, marketing, legal and other 

                                       24.

<PAGE>

factors, the outcome of which cannot be predicted. Virtually all of the 
operating companies are, and in the future will be, newly-formed entities 
that have a limited operating history and that operate at a loss for a 
substantial period of time. These operating companies will require 
significant amounts of additional financing to fund capital expenditures, 
working capital requirements and other cash needs, including the costs of 
obtaining additional licenses. In addition, there can be no assurance that 
these projects will not encounter engineering, design or other operational 
problems. For example, STW, the Company's Malaysian WLL operating company, 
has experienced significant delays in network deployment and its marketing 
plans primarily as a result of adverse effects on STW of an attempt during 
the first half of 1996 by the Malaysian government to consolidate the 
Malaysian telecommunications industry. See "--Risks Inherent in Foreign 
Investment." As a result, in late 1996, IWC and its principal strategic 
partner in STW extensively reviewed and revised STW's business plan and 
strategy. There can be no assurance that the Company can successfully develop 
any of its existing or planned developmental stage projects or that any of 
these projects or any of its operating companies will achieve commercial 
success. Further, the Company's current and anticipated ownership interests 
in the operating companies and developmental stage projects are subject to 
modification and may even be eliminated completely due to the occurrence of 
certain events such as the re-negotiation of existing MOUs and/or agreements, 
changes in foreign laws or regulations affecting foreign ownership, 
government expropriation, financing contingencies and other factors. 
Likewise, the Company may voluntarily withdraw from one or more operating 
companies and/or developmental stage projects. 

RISKS INHERENT IN FOREIGN INVESTMENT

     The Company has invested substantial resources outside of the United 
States and plans to continue to do so in the future. Governments of many 
developing countries have exercised and continue to exercise substantial 
influence over many aspects of the private sector. For example, foreign 
ownership of telecommunications ventures is prohibited in China. In addition, 
in some cases, the government owns or controls (i) companies that are or may 
in the future become competitors of the Company or (ii) companies (such as 
national telephone companies) upon which the operating companies and 
developmental stage projects may depend for required interconnections to 
land-line telephone networks and other services. Similarly, government 
actions in the future could have a significant adverse effect on economic 
conditions in a developing country or may otherwise have a material adverse 
effect on the Company and its operating companies and developmental stage 
projects. Expropriation, confiscatory taxation, nationalization, political, 
economic or social instability or other developments could materially 
adversely affect the value of the Company's interests in operating companies 
and developmental stage projects in particular developing countries. 

     For example, in early 1996 the Malaysian government announced a program 
designed to consolidate the Malaysian telecommunications industry which, if 
completed, would have forced the sale or merger of STW, the Company's 
Malaysian operating company, to one of a limited number of surviving 
telecommunications companies. Although the Malaysian government announced in 
July 1996 that it did not intend to proceed with this program, the activities 
of the Malaysian government in connection with such program resulted in 
significant delays in STW's network deployment and marketing plans thereby 
contributing to a 37% decrease in STW's subscribers during the quarter ended 
September 30, 1996. There can be no assurance that the Malaysian government 
will not initiate similar programs in the future. There can also be no 
assurance that the Malaysian national telephone company will not otherwise 
impose restrictions on STW, including restrictions on the ability of STW to 
interconnect its wireless network with the national telephone company's 
system, which could have a material adverse effect on the Company.  Moreover, 
there can be no assurance that other countries where the Company has 
operating companies or developmental stage projects will not initiate similar 
programs or impose other restrictions, which could have a material adverse 
effect on the Company. 

     The Company also may be adversely affected by political or social unrest 
or instability in foreign countries. Such unrest or instability resulting 
from political, economic, social or other conditions in foreign countries 
could have a material adverse effect on the Company. For example, in China, 
because foreign ownership of telecommunications operators is prohibited, the 
Company, through its ownership interest in SDL, has interests in China 
telecommunications projects through certain "cooperative agreements" with 
Chinese cellular operators. Pursuant to the terms of the cooperative 
agreements, SDL provides equipment and technical and engineering services to 
the cellular operators and, in return, is allocated a portion of the revenues 
or profits from the cellular operations. There can be no assurance that the 
Chinese government will not prohibit or otherwise impose restrictions on 
these types of arrangements, which could have a material adverse effect on 
the Company. 

                                       25.

<PAGE>

     The Company does not have political risk insurance in the countries in 
which it currently conducts business. Moreover, applicable agreements 
relating to the Company's interests in its operating companies are frequently 
governed by foreign law. As a result, in the event of a dispute, it may be 
difficult for the Company to enforce its rights. Accordingly, the Company may 
have little or no recourse upon the occurrence of any of these developments 
or if any of its partners seek to re-negotiate existing or future MOUs and/or 
other agreements. To the extent that any of the operating companies seeks to 
make a dividend or other distribution to the Company, or to the extent that 
the Company seeks to liquidate its investment in an operating company or 
developmental stage project and repatriate monies from a relevant country, 
local taxes, foreign exchange controls or other restrictions may effectively 
prevent the transfer of funds to the Company or the exchange of local 
currency for U.S. dollars. 

TECHNOLOGICAL RISK; RISK OF OBSOLESCENCE

     The Company's operating companies and developmental stage projects 
generally use new and emerging technologies. For example, SDL, the Company's 
China Regional Cellular project, is required by the Chinese government to 
migrate to CDMA, a cellular technology that is not widely deployed on a 
commercial basis at the present time. Additionally, the MPT 1327 ECTR 
technology selected by a number of the Company's ECTR operating companies is 
currently operational in many countries but has had limited deployment for 
public use in developing countries. Although many of the technologies 
currently in use and to be used in the future by the Company have been 
developed by international telecommunications companies such as Nokia, 
Philips, Motorola, Ericsson, Lucent Technologies and Nortel, most are 
generally advanced technologies which have only recently been developed and 
commercially introduced. There can be no assurance that the operating 
companies and developmental stage projects will not experience technical 
problems in the commercial deployment of these technologies, particularly 
because they are being introduced in developing countries. In addition, the 
technology used in wireless communications is evolving rapidly and one or 
more of the technologies currently utilized or planned by the Company to be 
utilized may be unpopular with its customers or may become obsolete, which in 
either case would likely have a material adverse effect on the Company. There 
can be no assurance that the Company will be able to keep pace with ongoing 
technological changes in the wireless telecommunications industry. 

RISK OF MODIFICATION OR LOSS OF LICENSES; UNCERTAINTY AS TO THE AVAILABILITY,
COST AND TERMS OF LICENSES; RESTRICTIONS ON LICENSES

     The Company's ability to retain and exploit the existing 
telecommunications licenses held by its operating companies and developmental 
stage projects, to renew such licenses when they expire, and to obtain new 
licenses in the future, are essential to the Company's operations. However, 
these licenses are typically granted by governmental agencies in developing 
countries, and there can be no assurance that these governmental agencies 
will not seek to unilaterally limit, revoke or otherwise adversely modify the 
terms of these licenses in the future, any of which could have a material 
adverse effect on the Company, and the Company may have limited or no legal 
recourse if any of these events were to occur. In addition, there can be no 
assurance that renewals to these licenses will be granted or, if renewed, 
that the renewal terms will not be substantially less favorable to the 
holders of the licenses than the original license terms, any of which could 
have a material adverse effect on the Company. Likewise, many of the 
Company's operating companies and developmental stage projects have not yet 
obtained all of the licenses necessary for their proposed operations, and no 
assurance can be given that any such licenses will be obtained. For example, 
the Brazilian government has not approved the transfer to Via 1, the 
Company's Brazilian ECTR operating company, of the licenses contributed or to 
be contributed to it by its current and proposed shareholders, and there can 
be no assurance that such approval will be obtained. The failure to obtain 
such approval or to obtain other licenses would have a material adverse 
effect on the Company. 

     The Company believes that the opportunity to acquire substantial new 
wireless licenses in developing countries will exist only for a limited time. 
Further, although the Company's operating companies and developmental stage 
projects have, to date, obtained many of their operating licenses through 
private negotiations without having to participate in competitive bidding 
processes, the Company anticipates that governments of developing countries 
will increasingly discover the value of new wireless technologies and may 
require bidding for licenses, which would likely increase the cost of these 
licenses, perhaps substantially. In addition, the operating companies and 
developmental stage projects may be required to purchase licenses from other 
license holders in certain circumstances, for example, to gain network 
capacity or to increase geographic coverage. Furthermore, relevant 
governmental authorities may grant 

                                       26.

<PAGE>

additional telecommunications licenses covering the same geographical areas 
as the operating companies' and developmental stage projects' licenses or 
otherwise grant licenses which allow other companies to compete directly with 
such operating companies and developmental stage projects for wireless 
subscribers. Although the inherent limitation on suitable frequency bands may 
provide some protection against the issuance of competing licenses, there can 
be no assurance that such competitive licenses will not be granted or, if 
granted, that they will not have a material adverse effect on the Company. In 
addition, licenses may be subject to significant operating restrictions or 
conditions, including restrictions on interconnection to the public telephone 
system or requirements that the operating companies or developmental stage 
projects complete construction or commence commercial operation of the 
networks by specified deadlines, which conditions, if not satisfied, may 
result in loss or revocation of the license. Accordingly, even if an 
operating company or developmental stage project is able to obtain a required 
license, there can be no assurance that such operating requirements will be 
satisfied and, as a result, there can be no assurance that such license will 
not be lost or revoked or that the restrictions imposed upon such license 
will prevent the commercial exploitation of such license, which could have a 
material adverse effect on the Company. 

DEPENDENCE ON OTHER TELECOMMUNICATIONS PROVIDERS

     The success of the Company's wireless systems will in many cases depend 
upon services provided by other telecommunications providers, some of which 
are competitors of the Company, the operating companies and/or the 
developmental stage projects. For example, the Company's operating companies 
and developmental stage projects generally require interconnection agreements 
with national or regional telephone companies in order for its wireless 
systems to connect with land-line telephone systems, and may require the use 
of microwave or fiber optic networks belonging to other parties to link its 
wireless systems. Although a number of operating companies have entered into 
required interconnection and/or linking agreements or have interconnection 
and/or linking arrangements in place, the revocation, loss or modification of 
any of these existing agreements or arrangements or the failure to obtain 
necessary agreements and/or arrangements in the future could have a material 
adverse effect on the Company. Specifically, STW, the Company's Malaysian WLL 
project, has in the past had difficulties obtaining interconnect services 
from its interconnect provider, which is a competitor of STW. In addition, 
STW's interconnect agreement expires in August 1997. Any failure of STW to 
obtain interconnect services pursuant to its interconnect agreement or to 
obtain a successor agreement would have a material adverse effect on STW. 

DEPENDENCE ON PARTNERS

     The Company will generally continue to depend on its local partners to 
obtain required licenses in all of its wireless projects. In addition, the 
Company may become dependent on strategic partners with resources beyond 
those of the Company to pursue larger scale projects, including certain WLL 
projects. In WLL projects, the Company may require the participation of a 
larger telecommunications company possessing the substantial capital and 
operating resources required to finance and deploy a WLL system. The failure 
of the Company to identify and enter into relationships with strong partners, 
or the failure of those partners to provide these resources, may have a 
material adverse effect on the Company. 

CONSTRUCTION RISKS

     The operating companies and developmental stage projects in which the 
Company invests typically require substantial construction of new wireless 
networks and additions to existing wireless networks. Construction activity 
will require the operating companies and developmental stage projects to 
obtain qualified subcontractors and necessary equipment on a timely basis, 
the availability of which varies significantly from country to country. 
Construction projects are subject to cost overruns and delays not within the 
control of the operating company or the developmental stage project or its 
subcontractors, such as those caused by acts of governmental entities, 
financing delays and catastrophic occurrences. Delays also can arise from 
design changes and material or equipment shortages or delays in delivery. 
Accordingly, there can be no assurance that the operating companies or 
developmental stage projects will be able to complete current or future 
construction projects for the amount budgeted or within the time periods 
projected, or at all. Failure to complete construction for the amount 
budgeted or on a timely basis could jeopardize subscriber contracts, 
franchises or licenses and could have a material adverse effect on the 
Company. In particular, telecommunications licenses often are granted on the 
condition that network construction be completed or commercial operations be 
commenced by a specified date. Failure to comply with these deadlines could 
result in the loss or revocation of the 

                                       27.

<PAGE>

licenses. In that regard, certain operating companies have failed to 
meet such deadlines in the past. Specifically, UTS, which provides ECTR 
services in the Visayas and Mindanao regions of the Philippines, failed 
to comply with the service date requirement contained in its provisional 
authority but subsequently cured such failure and expects to receive its 
final operating authority from the Philippine government by the end of 1997. 
Similarly, in the Via 1 Project, because the Company and its proposed 
partners were unable to comply with operations commencement deadlines 
with respect to their licenses, they had to apply for, and have 
received, extensions of such deadlines. Although such failures have not 
to date led to the loss of any licenses, there can be no assurance that 
the relevant governmental authorities will not seek to revoke licenses 
as a result of these past defaults or refuse to grant deadline 
extensions to similar defaults occurring in the future, which could have 
a material adverse effect on the Company. 

SUBSTANTIAL LEVERAGE

     As discussed above, the operating companies and developmental stage 
projects will require continuing sources of additional financing. Certain of 
the operating companies have substantial indebtedness and, to the extent that 
additional debt financing is available, such operating companies may incur 
additional indebtedness, and other operating companies or developmental stage 
projects may in the future incur substantial indebtedness, in relation to 
their respective base of equity capital. To the extent that any of the 
operating companies or developmental stage projects now has or in the future 
incurs a high level of indebtedness, such indebtedness will have important 
consequences to the Company, including (i) a possible restriction on such 
entity's ability to pay dividends or make other distributions to the Company, 
(ii) a possible limitation on such entity's ability to obtain additional debt 
financing and (iii) a possible impairment of such entity's ability to react 
to changes in the industry and economic conditions generally. 

COMPETITION

     Although the implementation of advanced wireless technologies is in the 
early stages of deployment in most developing countries, the Company believes 
that its business will become increasingly competitive, particularly as 
businesses and foreign governments realize the market potential of these 
wireless technologies. A number of large American, Japanese and European 
companies, including U.S.-based regional Bell operating companies ("RBOCs") 
and large international telecommunications companies, are actively engaged in 
programs to develop and commercialize wireless technologies in developing 
counties. In many cases, the Company will also compete against local 
land-line carriers, including government-owned telephone companies. Most of 
these companies have substantially greater financial and other resources, 
including research and development staffs and technical and marketing 
capabilities than the Company. The Company anticipates that there will be 
increasing competition for additional licenses and increased competition to 
the extent such licenses are obtained by others. Although the Company intends 
to employ relatively new technologies, there will be a continuing competitive 
threat from even newer technologies which may render the technologies 
employed by the Company obsolete. 

REGULATION

     The wireless services of the Company's operating companies and 
developmental stage projects are subject to governmental regulation, which 
may change from time to time. There can be no assurance that material and 
adverse changes in the regulation of the Company's existing or future 
operating companies or developmental stage projects will not occur in the 
future. To date, certain operating companies and developmental stage projects 
have been subject to foreign ownership restrictions, service requirements, 
restrictions on interconnection of wireless systems to government-owned or 
private telephone networks, subscriber rate-setting, technology and 
construction requirements, among others. These regulations may be difficult 
to comply with, particularly given demographic, geographic or other issues in 
a particular market. Further, changes in the regulatory framework may limit 
the ability to add subscribers to developing systems. An operating company's 
or developmental stage project's failure to comply with applicable 
governmental regulations or operating requirements could result in the loss 
of licenses or otherwise could have a material adverse effect on the Company. 

                                       28.

FOREIGN CORRUPT PRACTICES ACT

     The Company is subject to the Foreign Corrupt Practices Act ("FCPA"), 
which generally prohibits U.S. companies and their intermediaries from 
bribing foreign officials for the purpose of obtaining or keeping business or 
licenses or otherwise obtaining favorable treatment. Although the Company has 
taken precautions to comply with the FCPA, there can be no assurance that 
such precautions will protect the Company against liability under the FCPA, 
particularly as a result of actions which may in the past have been taken or 
which may be taken in the future by agents and other intermediaries for whose 
actions the Company may be held liable under the FCPA. In particular, the 
Company may be held responsible for actions taken by its strategic or local 
partners even though such strategic or local partners are themselves 
typically foreign companies which are not subject to the FCPA; and the 
Company has no ability to control such strategic or local partners. Any 
determination that the Company has violated the FCPA could have a material 
adverse effect on the Company.

TAX RISKS

     Distributions of earnings and other payments received from the Company's 
operating subsidiaries and affiliates are likely to be subject to withholding 
taxes imposed by the jurisdictions in which such entities are formed or 
operating. In general, a U.S. corporation may claim a foreign tax credit 
against its federal income tax expense for such foreign withholding taxes and 
foreign taxes paid directly by corporate entities in which the Company owns 
10% or more of the voting stock. The ability to claim such foreign tax 
credits and to utilize net foreign losses is, however, subject to numerous 
limitations, and the Company may incur incremental tax costs as a result of 
these limitations or because the Company is not in a tax paying position in 
the U.S. 

     Special U.S. tax rules apply to U.S. taxpayers that own stock in a 
"passive foreign investment company" (a "PFIC") that could also increase the 
Company's effective rate of taxation. In general, a non-U.S. corporation will 
be treated as a PFIC if at least 75 percent of its income is "passive income" 
or if at least 50 percent of its assets are held for the production of 
"passive income." A non-U.S. corporation that owns 25 percent or more of the 
stock of a non-U.S. subsidiary is treated as receiving a proportionate share 
of the income of, and as owning a proportionate share of the assets of, such 
subsidiary. 

     It is possible that certain operating companies in which the Company 
owns an equity interest are PFICs. Generally, except to the extent the 
Company makes an election to treat a PFIC in which it owns stock as a 
"qualified electing fund" (a "QEF") in the first taxable year in which the 
Company owns the PFIC's stock, (i) the Company would be required to allocate 
gain recognized upon the disposition of stock in the PFIC and income 
recognized upon receiving certain dividends ratably over the Company's 
holding period for the stock in the PFIC, (ii) the amount allocated to each 
year other than the year of the disposition or dividend payment would be 
taxable at the highest U.S. tax rate applicable to corporations, and an 
interest charge for the deemed deferral benefit would be imposed with respect 
to the tax attributable to each year, and (iii) gain recognized upon 
disposition of PFIC shares would be taxable as ordinary income. 

     If the Company were to make the QEF election, as described above, the 
Company would be required in each year that the PFIC qualification tests are 
met to include its pro rata share of the QEF's earnings as ordinary income 
and its pro rata share of the QEF's net capital gain as long-term capital 
gain, whether or not such amounts are actually distributed. The Company has 
not made any QEF elections with respect to any non-U.S. corporation in which 
it holds stock. 

     The Company may also be required to include in its income for U.S. 
income tax purposes its proportionate share of the earnings of those foreign 
corporate subsidiaries that are classified as "controlled" foreign 
corporations without regard to whether distributions have been received from 
such companies. 

                                       29.

     I.   PURPOSES OF THE PLAN

          This 1996 Stock Option/Stock Issuance Plan (the "Plan") was adopted by
International Wireless Communications Holdings, Inc., a Delaware corporation
(the "Corporation"), on August 8, 1996, the date upon which International
Wireless Communications, Inc. became a wholly-owned subsidiary of the
Corporation.  The Plan is intended to promote the interests of the Corporation
by providing a method whereby eligible individuals who provide valuable services
to the Corporation (or any Parent or Subsidiary) may be offered incentives and
rewards which will encourage them to acquire a proprietary interest, or
otherwise increase their proprietary interest, in the Corporation and continue
to render services to the Corporation (or any Parent or Subsidiary).

     II.  DEFINITIONS

          For the purposes of this Plan, the following definitions shall be in
effect:

          A.   BOARD shall mean the Corporation's Board of Directors.

          B.   CODE shall mean the Internal Revenue Code of 1986, as amended.

          C.   COMMITTEE shall mean a committee of two (2) or more Board members

     possessing more than fifty percent (50%) of the total combined voting power
     of the Corporation's outstanding securities are transferred to a person or
     persons different from those who held those securities immediately prior to
     such transaction, or

                    (ii)  the sale, transfer or other disposition of all or
     substantially all of the Corporation's assets in complete liquidation or
     dissolution of the Corporation.

     admitted to trading on any Stock Exchange but is traded on the Nasdaq
     National Market, the Fair Market Value shall be the closing price per share
     of Common Stock on the date in question, as such price is reported by the
     National Association of Securities Dealers on the Nasdaq National Market or
     any successor system. If there is no closing price for the Common Stock on
     the date in question, then the Fair Market Value shall be the closing price
     on the last preceding date for which such quotation exists.

                    (ii)  If the Common Stock is at the time listed or admitted
     to trading on any Stock Exchange, then the Fair Market Value shall be the
     closing selling price per share of Common Stock on the date in question on
     the Stock Exchange determined by the Plan Administrator to be the primary
     market for the Common Stock, as such price is officially quoted in the
     composite tape of transactions on such exchange. If there is no closing
     selling price for the Common Stock on the date in question, then the Fair
     Market Value shall be the closing selling price on the last preceding date
     for which such quotation exists.

                    (iii) If the Common Stock is at the time neither listed nor
     admitted to trading on any Stock Exchange nor traded on the NASDAQ National
     Market System, then such Fair Market Value shall be determined by the Plan

     Administrator shall deem appropriate.

fifty percent (50%) or more of the total combined voting power of all classes of
stock in one of the other corporations in such chain.

          X.   10% STOCKHOLDER shall mean the owner of stock (as determined

combined voting power of all classes of stock of the Corporation.

          Y.   TREASURY SHARES shall mean shares of Common Stock reacquired by
the Corporation and held as treasury shares.

     III. STRUCTURE OF THE PLAN

          A.   The Plan shall be divided into two (2) separate components:

                                       3

<PAGE>

Three. Under the Option Grant Program, eligible individuals may, at the 
discretion of the Plan Administrator, be granted options to purchase shares 
of Common Stock in accordance with the provisions of Article Two. Under the 
Stock Issuance Program, eligible individuals may be issued shares of Common 
Stock directly, either through the immediate purchase of such shares at a 
price not less than eighty-five percent (85%) of the fair market value of the 
shares at the time of issuance or as a bonus for services rendered the 
Corporation without any cash payment required of the recipient.

          B.   The provisions of Articles One and Four of the Plan shall apply
to both the Option Grant Program and the Stock Issuance Program and shall
accordingly govern the interests of all individuals under the Plan.

     IV.  ADMINISTRATION OF THE PLAN

          A.   The Plan shall be administered by the Board. However, any or all 
administrative functions otherwise exercisable by the Board may be delegated to
the Committee. Members of the Committee shall serve for such period of time as
the Board may determine and shall be subject to removal by the Board at any
time. The Board may also at any time terminate the functions of the Committee
and reassume all powers and authority previously delegated to the Committee.

          B.   The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Plan and to make
such determinations under, and issue such interpretations of, the Plan and any
outstanding options as it may deem necessary or advisable. Decisions of the Plan
Administrator shall be final and binding on all parties who have an interest in
the Plan or any outstanding option.

     V.   OPTION GRANTS AND SHARE ISSUANCES

          A.   The persons eligible to participate in the Option Grant Program
and the Stock Issuance Program shall be limited to the following:

                    (i)   Employees,

                    (ii)  non-employee members of the Board or the non-employee
     members of the board of directors of any Parent or Subsidiary, and

                    (iii) consultants and other independent contractors who
     provide valuable services to the Corporation (or any Parent or Subsidiary).

          B.   The Plan Administrator shall have full authority to determine,
(i) with respect to the option grants under the Plan, which eligible individuals
are to receive option grants, the number of shares to be covered by each such
grant, the status of the granted option as either an Incentive Option or a Non-
Statutory Option, the time or times at which each option is to become
exercisable and the maximum term for which the option is to remain outstanding,
and (ii) with respect to share issuances under the Stock Issuance Program, the
number of shares to be 

                                       4

<PAGE>

issued to each Participant, the vesting schedule (if any) to be applicable to 
the issued shares and the consideration to be paid by the Participant for 
such shares.

          C.   The Plan Administrator shall have the absolute discretion either
to grant options in accordance with Article Two or to effect share issuances in
accordance with Article Three.

     VI.  STOCK SUBJECT TO THE PLAN

          A.   The stock issuable under the Plan shall be shares of the
Corporation's authorized but unissued or reacquired Common Stock.  The maximum
number of shares which may be issued over the term of the Plan shall not exceed
2,811,526 shares.  Such authorized share reserve is comprised of the number of
shares which remained available for issuance, as of the Plan effective date,
under the Predecessor Plan, including the shares subject to the outstanding
options incorporated into the Plan and any other shares which would have been
available for future option grants under the Predecessor Plan and a share
increase of 411,526 shares approved by the Board on February 3, 1997, subject to
the approval of the Corporation's stockholders.  Such authorized share reserve
is also subject to adjustment from time to time in accordance with Section VI.C
of this Article One.  

          B.   Shares subject to outstanding options shall be available for
subsequent issuance under the Plan to the extent (i) the options (including any
options incorporated from the Predecessor Plan) expire or terminate for any
reason prior to exercise in full or (ii) the options are canceled in accordance
with the cancellation/regrant provisions of Section IV. of Article Two. All
shares issued under the Plan (including shares issued upon exercise of options
incorporated from the Predecessor Plan), whether or not those shares are
subsequently repurchased by the Corporation pursuant to its repurchase rights
under the Plan, shall reduce on a share-for-share basis the number of shares of
Common Stock available for issuance under the Plan.

          C.   In the event any change is made to the Common Stock issuable
under the Plan by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be made to (i) the maximum number
and/or class of securities under the Plan and (ii) the number and/or class of
securities and the exercise price per share in effect under each outstanding
option (including any option incorporated from the Predecessor Plan) in order to
prevent the dilution or enlargement of benefits thereunder. The adjustments
determined by the Plan Administrator shall be final, binding and conclusive. In
no event shall any adjustments be made for the conversion of one or more
outstanding series of the Corporation's preferred stock into shares of the
Common Stock.

                              OPTION GRANT PROGRAM

     I.   TERMS AND CONDITIONS OF OPTIONS

          Options granted pursuant to the Plan shall be authorized by action of
the Plan Administrator and may, at the Plan Administrator's discretion, be
either Incentive Options or Non-Statutory Options. Each granted option shall be
evidenced by one or more instruments in the form approved by the Plan
Administrator, provided, however, that each such instrument shall comply with
the terms and conditions specified below. Each instrument evidencing an
Incentive Option shall, in addition, be subject to the applicable provisions of
Section II of this Article Two.

          A.   EXERCISE PRICE.

               1.   The exercise price per share shall be fixed by the Plan
Administrator. In no event, however, shall the exercise price per share be less
than eighty-five percent (85%) of the Fair Market Value per share of Common
Stock on the date of the option grant.

               2.   If the individual to whom the option is granted is a 10%
Stockholder, then the exercise price per share shall not be less than one
hundred ten percent (110%) of the Fair Market Value per share of Common Stock on
the grant date.

               3.   The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Four and the agreement evidencing the grant, be payable in cash or check
made payable to the Corporation. Should the Corporation's outstanding Common
Stock be registered under Section 12(g) of the Exchange Act at the time the
option is exercised, then the exercise price may also be paid as follows:

                    (i)  in shares of Common Stock held by the Optionee for the
     requisite period necessary to avoid a charge to the Corporation's earnings
     for financial reporting purposes and valued at Fair Market Value on the
     Exercise Date, or

                    (ii) through a special sale and remittance procedure
     pursuant to which the Optionee shall concurrently provide irrevocable
     written instructions (a) to a Corporation-designated brokerage firm to
     effect the immediate sale of the purchased shares and remit to the
     Corporation, out of the sale proceeds available on the settlement date,
     sufficient funds to cover the aggregate exercise price payable for the
     purchased shares plus all applicable Federal, state and local income and
     employment taxes required to be withheld by the Corporation by reason of
     such purchase and (b) to the Corporation to deliver the certificates for
     the purchased shares directly to such brokerage firm in order to complete
     the sale transaction.

                                       6

<PAGE>

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   TERM AND EXERCISE OF OPTIONS.  Each option granted under the Plan
shall be exercisable at such time or times, during such period and for such
number of shares as shall be determined by the Plan Administrator and set forth
in the stock option agreement. However, no option shall have a term in excess of
ten (10) years measured from the grant date. The option shall be exercisable
during the Optionee's lifetime only by the Optionee and shall not be assignable
or transferable other than by will or by the laws of descent and distribution
following the Optionee's death or pursuant to a qualified domestic relations
order as defined by the Code.

          C.   EFFECT OF TERMINATION OF SERVICE.

               1.   Except to the extent otherwise provided pursuant to
subsection C.2 below, the following provisions shall govern the exercise period
applicable to any options held by the Optionee at the time of cessation of
Service or death:

                    (i)   Should the Optionee cease to remain in Service for any
     reason other than death or Permanent Disability, then the period during
     which each outstanding option held by such Optionee is to remain
     exercisable shall be limited to the three (3)-month period following the
     date of such cessation of Service.

                    (ii)  Should such Service terminate by reason of Permanent
     Disability, then the period during which each outstanding option held by
     the Optionee is to remain exercisable shall be limited to the twelve (12)-
     month period following the date of such cessation of Service.

                    (iii) Should the Optionee die while holding one or more
     outstanding options, then the period during which each such option is to
     remain exercisable shall be limited to the twelve (12)-month period
     following the date of the Optionee's death. During such limited period, the
     option may be exercised by the personal representative of the Optionee's
     estate or by the person or persons to whom the option is transferred
     pursuant to the Optionee's will or in accordance with the laws of descent
     and distribution.

                    (iv)  Under no circumstances, however, shall any such option
     be exercisable after the specified expiration date of the option term.

                    (v)   During the applicable post-Service exercise period,
     the option may not be exercised in the aggregate for more than the number
     of vested shares for which the option is exercisable on the date of the
     Optionee's cessation of Service. Upon the expiration of the applicable
     exercise period or (if earlier) upon the expiration of the option term, the
     option shall terminate and cease to be exercisable for any vested shares
     for which the option has not been exercised. However, the option shall,
     immediately upon the Optionee's cessation of Service, terminate and cease
     to be outstanding with respect to any option 

                                       7

<PAGE>

     shares for which the option is not at that time exercisable or in which the
     Optionee is not otherwise at that time vested.

               2.   The Plan Administrator shall have full power and authority
to extend the period of time for which the option is to remain exercisable
following the Optionee's cessation of Service or death from the limited period
in effect under subsection C.1 of this Article Two to such greater period of
time as the Plan Administrator shall deem appropriate; PROVIDED, that in no
event shall such option be exercisable after the specified expiration date of
the option term.

          D.   STOCKHOLDER RIGHTS.  An Optionee shall have no stockholder rights
with respect to the shares subject to the option until such individual shall
have exercised the option and paid the exercise price.

          E.   UNVESTED SHARES.  The Plan Administrator shall have the
discretion to authorize the issuance of unvested shares of Common Stock under
the Plan. Should the Optionee cease Service while holding such unvested shares,
the Corporation shall have the right to repurchase, at the exercise price paid
per share, all or (at the discretion of the Corporation and with the consent of
the Optionee) any of those unvested shares. The terms and conditions upon which
such repurchase right shall be exercisable (including the period and procedure
for exercise and the appropriate vesting schedule for the purchased shares)
shall be established by the Plan Administrator and set forth in the agreement
evidencing such repurchase right. All outstanding repurchase rights under the
Plan shall terminate automatically upon the occurrence of any Corporate
Transaction, except to the extent the repurchase rights are expressly assigned
to the successor corporation (or parent thereof) in connection with the
Corporate Transaction.

          F.   FIRST REFUSAL RIGHTS.  Until such time as the Corporation's
outstanding shares of Common Stock are first registered under Section 12(g) of
the Exchange Act, the Corporation shall have the right of first refusal with
respect to any proposed sale or other disposition by the Optionee (or any
successor in interest by reason of purchase, gift or other transfer) of any
shares of Common Stock issued under the Plan. Such right of first refusal shall 
be exercisable in accordance with the terms and conditions established by the
Plan Administrator and set forth in the agreement evidencing such right.

     II.  INCENTIVE OPTIONS

          The terms and conditions specified below shall be applicable to all
Incentive Options granted under the Plan. Except as modified by the provisions
of this Section II, all the provisions of Articles One, Two and Four shall be
applicable to Incentive Options. Incentive Options may only be granted to
individuals who are Employees. Options which are specifically designated as
Non-Statutory shall NOT be subject to such terms and conditions.

          A.   EXERCISE PRICE.  The exercise price per share of the Common Stock
subject to an Incentive Option shall in no event be less than one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the date of
grant.

          B.   DOLLAR LIMITATION.  The aggregate Fair Market Value of the Common
Stock (determined as of the respective date or dates of grant) for which one (1)
or more options 

                                       8

<PAGE>

granted to any Employee under this Plan (or any other option plan of the 
Corporation or any Parent or Subsidiary) may for the first time become 
exercisable as Incentive Options during any one (1) calendar year shall not 
exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the 
Employee holds two (2) or more such options which become exercisable for the 
first time in the same calendar year, the foregoing limitation on the 
exercisability of such options as Incentive Options shall be applied on the 
basis of the order in which such options are granted. Should the applicable 
One Hundred Thousand Dollar ($100,000) limitation in fact be exceeded in any 
calendar year, then the option shall nevertheless become exercisable for the 
excess number of shares in such calendar year as a Non-Statutory Option.

          C.   10% STOCKHOLDER.  If any individual to whom an Incentive Option
is granted is a 10% Stockholder, then the option term shall not exceed five (5)
years measured from the grant date.

     III. CORPORATE TRANSACTION

          A.   Upon the occurrence of a Corporate Transaction, each option at
the time outstanding under the Plan shall terminate and cease to be exercisable,
except to the extent assumed by the successor corporation or parent thereof.

          B.   Each outstanding option which is assumed in connection with a
Corporate Transaction or is otherwise to remain outstanding shall be
appropriately adjusted, immediately after such Corporate Transaction, to apply
and pertain to the number and class of securities which would have been issuable
to the Optionee in the consummation of such Corporate Transaction, had the
option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the class and number of
securities available for issuance under the Plan following the consummation of
such Corporate Transaction, and (ii) the exercise price payable per share,
PROVIDED the aggregate exercise price payable for such securities shall remain
the same.

          C.   The grant of options under this Plan shall in no way affect the
right of the Corporation to adjust, reclassify, reorganize or otherwise change
its capital or business structure or to merge, consolidate, dissolve, liquidate
or sell or transfer all or any part of its business or assets.

     IV.  CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options (including outstanding options
incorporated from the Predecessor Plan) under the Plan and to grant in
substitution therefor new options under the Plan covering the same or different
numbers of shares of Common Stock but with an exercise price per share not less 
than (i) one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the new grant date in the case of a grant of an Incentive Option, (ii)
one hundred ten percent (110%) of such Fair Market Value in the case of an
option grant to a 10% Stockholder or (iii) eighty-five percent (85%) of such
Fair Market Value in the case of all other grants.

                                  ARTICLE THREE

                             STOCK ISSUANCE PROGRAM

     I.   TERMS AND CONDITIONS OF STOCK ISSUANCES

          Shares may be issued under the Stock Issuance Program through direct
and immediate issuances without any intervening stock option grants. Each such
stock issuance shall be evidenced by a Restricted Stock Purchase Agreement
("Purchase Agreement") which complies with each of the terms and conditions of
this Article Three.

          A.   ISSUE PRICE

               1.   The purchase price per share shall be fixed by the Plan
Administrator, but in no event shall the purchase price per share of Newly
Issued Shares be less than eighty-five percent (85%) of the Fair Market Value
per share of Common Stock on the date of issuance.

               2.   If the individual to whom a share issuance is made is a 10% 
Stockholder, then the purchase price per share shall not be less than one
hundred ten percent (110%) of the Fair Market Value per share of Common Stock on
the issuance date.

               3.   Newly Issued Shares shall be issued under the Plan for such 
consideration as the Plan Administrator shall from time to time determine,
provided that, except as set forth in Section I of Article Four, in no event
shall shares be issued for consideration other than

                    (i)   cash or check made payable to the Corporation, or

                    (ii)  past services rendered to the Corporation or any 
     Parent or Subsidiary.

               4.   Treasury Shares may be issued under the Plan for such
consideration (including one or more of the items of consideration specified in
subparagraph 3 above) as the Plan Administrator may deem appropriate. Treasury
Shares may, in lieu of any cash consideration, be issued subject to such vesting
requirements tied to the Participant's period of future Service or the
Corporation's attainment of specified performance objectives as the Plan
Administrator may establish at the time of issuance.

          B.   VESTING PROVISIONS

               1.   Shares of Common Stock issued under the Stock Issuance
Program may, in the absolute discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service. The elements of the vesting schedule
applicable to any unvested shares of Common Stock issued under the Stock
Issuance Program, namely:

                    (i)   the Service period to be completed by the Participant
     or the performance objectives to be achieved by the Corporation,

                                       10

<PAGE>

                    (ii)  the number of installments in which the shares are to
     vest,

                    (iii) the interval or intervals (if any) which are to lapse
     between installments, and

                    (iv)  the effect which death, Permanent Disability or other
     event designated by the Plan Administrator is to have upon the vesting
     schedule,

shall be determined by the Plan Administrator and incorporated into the Purchase
Agreement executed by the Corporation and the Participant at the time such
unvested shares are issued.

               2.   The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to him or her under the Plan,
whether or not his or her interest in those shares is vested. Accordingly, the
Participant shall have the right to vote such shares and to receive any regular
cash dividends paid on such shares. Any new, additional or different shares of
stock or other property (including money paid other than as a regular cash
dividend) which the Participant may have the right to receive with respect to
his unvested shares by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration or by reason of any Corporate Transaction shall be
issued subject to (i) the same vesting requirements applicable to the
Participant's unvested shares and (ii) such escrow arrangements as the Plan
Administrator shall deem appropriate.

               3.   Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock under the Stock Issuance
Program, then those shares shall be immediately surrendered to the Corporation
for cancellation, and the Participant shall have no further stockholder rights
with respect to those shares. To the extent the surrendered shares were
previously issued to the Participant for consideration paid in cash or cash
equivalent (including the Participant's purchase-money promissory note), the
Corporation shall repay to the Participant the cash consideration paid for the
surrendered shares and shall cancel the unpaid principal balance of any
outstanding purchase-money note of the Participant attributable to such
surrendered shares. The surrendered shares may, at the Plan Administrator's
discretion, be retained by the Corporation as Treasury Shares or may be retired
to authorized but unissued share status.

               4.   The Plan Administrator may in its discretion elect to waive
the surrender and cancellation of one or more unvested shares of Common Stock
(or other assets attributable thereto) which would otherwise occur upon the non-
completion of the vesting schedule applicable to such shares. Such waiver shall
result in the immediate vesting of the Participant's interest in the shares of
Common Stock as to which the waiver applies. Such waiver may be effected at any
time, whether before or after the Participant's cessation of Service or the
attainment or non-attainment of the applicable performance objectives.

          C.   FIRST REFUSAL RIGHTS.  Until such time as the Corporation's
outstanding shares of Common Stock are first registered under Section 12(g) of
the Exchange Act, the Corporation shall have a right of first refusal with
respect to any proposed disposition by the 

                                       11

<PAGE>

Participant (or any successor in interest by reason of purchase, gift or 
other transfer) of any shares of Common Stock issued under the Plan. Such 
right of first refusal shall be exercisable in accordance with the terms and 
conditions established by the Plan Administrator and set forth in the 
agreement evidencing such right.

     II.  SHARE ESCROW/TRANSFER RESTRICTIONS

          A.   SHARE ESCROW.  Unvested shares may, in the Plan Administrator's
discretion, be held in escrow by the Corporation until the Participant's
interest in such shares vests or may be issued directly to the Participant with
restrictive legends on the certificates evidencing such unvested shares. To the
extent an escrow arrangement is utilized, the unvested shares and any securities
or other assets issued with respect to such shares (other than regular cash
dividends) shall be delivered in escrow to the Corporation to be held until the
Participant's interest in such shares (or other securities or assets) vests.
Alternatively, if the unvested shares are issued directly to the Participant,
the restrictive legend on the certificates for such shares shall read
substantially as follows:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE UNVESTED AND ARE
          ACCORDINGLY SUBJECT TO (I) CERTAIN TRANSFER RESTRICTIONS AND (II)
          CANCELLATION OR REPURCHASE IN THE EVENT THE REGISTERED HOLDER (OR
          HIS/HER PREDECESSOR IN INTEREST) CEASES TO REMAIN IN THE
          CORPORATION'S SERVICE. SUCH TRANSFER RESTRICTIONS AND THE TERMS
          AND CONDITIONS OF SUCH CANCELLATION OR REPURCHASE ARE SET FORTH
          IN A STOCK PURCHASE AGREEMENT BETWEEN THE CORPORATION AND THE
          REGISTERED HOLDER (OR HIS/HER PREDECESSOR IN INTEREST) DATED
          __________, 199__ A COPY OF WHICH IS ON FILE AT THE PRINCIPAL
          OFFICE OF THE CORPORATION."

          B.   TRANSFER RESTRICTIONS.  The Participant shall have no right to
transfer any unvested shares of Common Stock issued to him or her under the
Stock Issuance Program. For purposes of this restriction, the term "transfer"
shall include (without limitation) any sale, pledge, assignment, encumbrance,
gift, or other disposition of such shares, whether voluntary or involuntary.
Upon any such attempted transfer, the unvested shares shall immediately be
cancelled in accordance with substantially the same procedure in effect under
Section I.B.3 of this Article Three, and neither the Participant nor the
proposed transferee shall have any rights with respect to such cancelled shares.
However, the Participant shall have the right to make a gift of unvested shares
acquired under the Stock Purchase Program to his or her spouse or issue,
including adopted children, or to a trust established for such spouse or issue,
provided the donee of such shares delivers to the Corporation a written
agreement to be bound by all the provisions of the Stock Issuance Program and
the Purchase Agreement applicable to the gifted shares.

     III. CORPORATE TRANSACTION

          All of the Corporation's outstanding repurchase rights under this
Article Three shall automatically terminate upon the occurrence of a Corporate
Transaction, except to the 

                                       12

<PAGE>

extent the Corporation's outstanding repurchase rights are to be assigned to 
the successor corporation (or parent thereof) in connection with the 
Corporate Transaction.

                                  ARTICLE FOUR

                                  MISCELLANEOUS

     I.   LOANS

          A.   The Plan Administrator may assist any Optionee or Participant,
other than a non-employee Board member, in the exercise of one or more options
granted to the Optionee under Article Two or the purchase of one or more shares
issued to the Participant under Article Three by:

                    (i)   authorizing the extension of a loan from the
     Corporation to the Optionee or Participant, or

                    (ii)  permitting the Optionee or Participant to pay the
     exercise price or purchase price in installments over a period of years.

          B.   The terms of any loan or installment method of payment (including
the interest rate and terms of repayment) shall be established by the Plan
Administrator in its sole discretion. Loans or installment payments may be
authorized with or without security or collateral. In all events, the maximum
credit available to each Optionee or Participant may not exceed the SUM of (i)
the aggregate exercise price or purchase price payable for the purchased shares
(less the par value of such shares) plus (ii) any Federal, state and local
income and employment tax liability incurred by the Optionee or Participant in
connection with such exercise or purchase.

          C.   The Plan Administrator may, in its absolute discretion, determine
that one or more loans extended under this Section I shall be subject to
forgiveness by the Corporation in whole or in part upon such terms and
conditions as the Plan Administrator may in its discretion deem appropriate.

     II.  NO EMPLOYMENT OR SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary) or of the Optionee or the Participant, which
rights are hereby expressly reserved by each, to terminate the Service of the
Optionee or Participant at any time for any reason, with or without cause.

     III. AMENDMENT OF THE PLAN AND AWARDS

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects whatsoever. However, no such
amendment or modification shall adversely affect the rights and obligations of
an Optionee with respect to options at the time outstanding under the Plan, nor
adversely affect the rights of any Participant with respect to Common Stock
issued under the Plan prior to such action, unless the Optionee or Participant
consents to such amendment. In addition, the Board shall not, without the
approval of the Corporation's stockholders, (i) increase the maximum number of
shares issuable under the 

                                       14

<PAGE>

Plan, except for permissible adjustments under Section VI.C of Article One, 
(ii) materially modify the eligibility requirements for participation in the 
Plan or (iii) otherwise materially increase the benefits accruing to 
individuals who participate in the Plan.

          B.   The Plan was restated on February 3, 1997 to increase by 411,526
the number of shares of the Corporation's Common Stock reserved for issuance
under the Plan from 2,400,000 shares to 2,811,526 shares.  Options to purchase
shares of Common Stock may be granted under Article Two and shares of Common
Stock may be issued under Article Three that are in both instances in excess of
the number of shares then available for issuance under the Plan, PROVIDED any
excess shares actually issued are held in escrow until there is obtained
stockholder approval of an amendment sufficiently increasing the number of
shares of Common Stock available for issuance under the Plan. If such
stockholder approval is not obtained within twelve (12) months after the date
the initial excess issuances are made, whether as stock option grants or direct
stock issuances, then (i) any unexercised options representing such excess shall
terminate and cease to be exercisable and (ii) the Corporation shall promptly
refund to the Optionees and Participants the exercise or purchase price paid for
any excess shares issued under the Plan and held in escrow, together with
interest (at the applicable Short-Term Federal Rate) for the period the shares
were held in escrow, and such shares shall thereupon be automatically cancelled
and cease to be outstanding.

     IV.  EFFECTIVE DATE AND TERM OF PLAN

          A.   The Plan shall become effective when adopted by the Board, but no
option granted under the Plan may be exercised until the Plan is approved by the
Corporation's stockholders.  If such stockholder approval is not obtained within
twelve (12) months after the date of the Board's adoption of the Plan, then all
options previously granted under the Plan shall terminate and cease to be
outstanding, and no further options shall be granted.  Subject to such
limitation, the Plan Administrator may grant options under the Plan at any time
after the effective date of the Plan and before the date fixed herein for
termination of the Plan. 

          B.   The Plan shall serve as the successor to the Predecessor Plan,
and no further option grants shall be made under the Predecessor Plan after the
Plan effective date.  All options outstanding under the Predecessor Plan as of
such date shall, immediately upon approval of the Plan by the Corporation's
stockholders, be incorporated into the Plan and treated as outstanding options
under the Plan.  However, each outstanding option so incorporated shall continue
to be governed solely by the terms of the documents evidencing such option, and
no provision of the Plan shall be deemed to affect or otherwise modify the
rights or obligations of the holders of such incorporated options with respect
to their acquisition of shares of Common Stock.

          C.   The Plan shall terminate upon the EARLIEST of (i) the expiration
of the ten (10)-year period measured from the date the Plan is adopted by the
Board, (ii) the date on which all shares available for issuance under the Plan
shall have been issued or (iii) the termination of all outstanding options under
Section III of Article Two.  Each option and unvested share issuance outstanding
under the Plan at such time shall continue to have full force and effect in
accordance with the provisions of the agreements evidencing that option or share
issuance.

                                       15

<PAGE>

     V.   USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

     VI.  WITHHOLDING

          The Corporation's obligation to deliver shares upon the exercise of
any options granted under Article Two or upon the purchase of any shares issued
under Article Three shall be subject to the satisfaction of all applicable
Federal, state and local income and employment tax withholding requirements.

     VII. REGULATORY APPROVALS

          The implementation of the Plan, the granting of any options under
Article Two and the issuance of Common Stock upon (i) the exercise of any option
or (ii) a direct issuance under Article Three shall be subject to the
Corporation's procurement of all approvals and permits required by regulatory
authorities having jurisdiction over the Plan, the options granted under it and
the Common Stock issued pursuant to it.

     VIII.     FINANCIAL REPORTS

          The Corporation shall deliver at least annually to each Optionee
holding an outstanding option under the Plan and to each Participant holding a
right to purchase stock under the Plan the same financial information furnished
to holders of the Common Stock unless the Optionee or Participant is a key
employee whose duties in connection with the Corporation assure such individual
access to equivalent information.

          2.   BUSINESS OF THE COMPANY.  The business of the Company shall be to

          3.   RESTRICTIONS ON TRANSFER OF SHARES.

               3.1  LIMITATION ON TRANSFER.  No Shareholder shall sell, give,
transfer, assign, charge, mortgage, hypothecate, pledge, encumber, grant a
security interest in or otherwise dispose of (whether by operation of law or

therein or thereto, except as expressly permitted by this Article 3.  Any
attempt to Transfer any Securities or any rights therein or thereto in violation
of this Article 3 shall be null and void AB INITIO, and the Company shall not
register any such Transfer.

               3.2  TRANSFERS IN COMPLIANCE WITH LAW.  Notwithstanding any other
provision of this Agreement, no Transfer may be made pursuant to this Article 3
unless (a) the transferee has agreed in writing to be bound by the terms and
conditions of this Agreement pursuant to a Deed of Adherence substantially in
the form attached hereto as Exhibit A, (b) the Transfer complies in all respects
with the applicable provisions of this Agreement and (c) the Transfer complies
in all respects with applicable securities laws.  If requested by the Company in
its reasonable discretion, an opinion of counsel to such transferring
Shareholder shall be supplied to the Company, at such transferring Shareholder's
expense, to the effect that such Transfer complies with applicable securities
laws.

               3.3  AFFILIATE TRANSFERS.  

                    3.3.1  PERMITTED TRANSFEREES.  Any Shareholder may Transfer
some or all of the Securities held by such Shareholder to an Affiliate of such
Shareholder without

<PAGE>

                                                                           5

compliance with the provisions of Section 3.4.  The parties agree that IWC 
(or IWC's Affiliates) and Vanguard (or Vanguard's Affiliates) shall have the 
right to transfer some or all of the Securities held by them to each other or 
to an Affiliate established by IWC or Vanguard without compliance with the 
provisions of Section 3.4.

                    3.3.2  CHANGE IN STATUS.  If Securities are Transferred by a
Shareholder to an Affiliate of such Shareholder and such transferee shall at any
time cease to be an Affiliate of such Shareholder, such Shareholder shall notify
the other Shareholders of such an event within five business days after the
occurrence of such an event, and such Securities shall be transferred (i) back
to the original Shareholder or (ii) to another Affiliate of that Shareholder
without compliance with the provisions of Section 3.4.

                    3.3.3  COMBINED HOLDINGS.  The Securities held by a
Shareholder and such Shareholder's Affiliates shall for all purposes of this
Agreement be treated as Securities held by a single Shareholder; provided,
however, that for the avoidance of doubt, Vanguard (or Vanguard's Affiliates)
shall not be deemed to be an Affiliate of IWC (or IWC's Affiliates) for the
purposes of this sentence.

                    In the case of a Transfer to an Affiliate, (i) the
Shareholder shall remain liable for any and all of its obligations under this
Agreement; (ii) STHL and IWC shall remain liable for any and all of their
respective obligations under the Subscription Agreement; and (iii) Vanguard and
STHL shall remain liable for any and all of their respective obligations under
the Stock Purchase Agreement; provided, however that the foregoing shall not
apply to Transfers to IWC or IWC's Affiliates by Vanguard or Vanguard's
Affiliates or to Vanguard or Vanguard's Affiliates by IWC or IWC's Affiliates,
in each case made pursuant to Section 3.3.1 with respect to the Shares so
Transferred.

               3.4  RIGHT OF FIRST REFUSAL AND RIGHT OF CO-SALE.  Each
Shareholder (each, a "Transferor") who proposes to Transfer Securities to a
third party (a "Third Party Purchaser") other than pursuant to Sections 3.3,
3.6, 3.7 or 3.8, grants to each other Shareholder (a "Section 3.4 Rightholder")
a right of first refusal ("Right of First Refusal") to purchase such Section 3.4
Rightholder's pro-rata share of the Transferor's Securities and a pro-rata right
of co-sale to participate in such Transfer ("Right of Co-Sale") exercisable at
the option of each Section 3.4 Rightholder in accordance with Section 3.4(b).

                    (a)  Each Transferor shall furnish to each Section 3.4
Rightholder written notice (the "Transferor Notice") of the intended
disposition, including the identity of the Third Party Purchaser, the number of
Securities to be Transferred (the "Offered Securities"), the price at which the
Securities are proposed to be Transferred and the general terms upon which such
Transfer is proposed to be made.

                    (b)  Subject to Sections 3.4(c) and 3.4(d), each Section 3.4
Rightholder shall have 21 calendar days (the "Notice Period") after the receipt
of the Transferor Notice (i) to agree irrevocably to purchase up to its pro-rata
share of the Offered Securities for the price and upon the general terms
specified in the Transferor Notice by giving written notice 

<PAGE>

                                                                           6


to the Transferor and stating therein the quantity of the Offered Securities 
to be purchased (each such Section 3.4 Rightholder exercising such right 
being referred to herein as a "Section 3.4 Purchaser") or (ii) to agree 
irrevocably to participate in the Transfer at the price and upon the general 
terms specified in the notice by giving written notice to the Transferor and 
stating therein the number of the Section 3.4 Rightholder's Securities to be 
sold (each such Section 3.4 Rightholder exercising such right being referred 
to herein as a "Section 3.4 Seller").  Failure by a Section 3.4 Rightholder 
to respond within such Notice Period shall be regarded as a waiver of its 
Right of First Refusal and its Right of Co-Sale with respect to the Transfer 
of the Offered Securities.  A Section 3.4 Rightholder may exercise either its 
Right of First Refusal or its Right of Co-Sale pursuant to this Section 3.4, 
but may not exercise both such rights with respect to any single proposed 
Transfer of Offered Securities.

                    (c)  Each Transferor shall, promptly after the end of the
Notice Period, give written notice (the "Last-Chance Notice") to all Section 3.4
Rightholders stating whether the Offered Securities have been fully subscribed
for by the Section 3.4 Purchasers, and, if not, the number of Offered Securities
not so subscribed-for (the "Remaining Offered Securities"), together with
information describing any exercise of Rights of Co-Sale by any Shareholders. 
Subject to Section 3.4(d), each Section 3.4 Purchaser shall have the right, but
not the obligation, to purchase all, but not less than all, of the Remaining
Offered Securities.  The right of each Section 3.4 Purchaser to purchase the
Remaining Offered Securities shall be exercisable irrevocably by written notice
delivered to each Transferor, with a copy to the Company, given within ten
calendar days (the "Last Chance Period") after receipt of the Last-Chance
Notice.  If more than one Section 3.4 Purchaser timely elects to exercise its
right to purchase the Remaining Offered Securities, the right to purchase the
Remaining Offered Securities shall be allocated pro rata among those Section 3.4
Purchasers electing to purchase the Remaining Offered Securities, based on the
proportion that the number of Securities owned by such Section 3.4 Purchaser
bears to the total number of Securities owned by all Section 3.4 Purchasers that
elect to purchase the Remaining Offered Securities.  A failure of any Section
3.4 Purchaser to exercise such right within the Last Chance Period shall be
regarded as a waiver of its right to purchase such Remaining Offered Securities
as provided herein.

                    (d)  Notwithstanding anything in this Article 3 to the
contrary, the right of the Section 3.4 Purchasers to purchase any of the Offered
Securities pursuant to this Article 3 shall be exercisable if and only if the
Section 3.4 Purchasers collectively have exercised their rights to purchase all,
but not less than all, of the Offered Securities pursuant to this Section 3.4. 
Any exercise by any Shareholder of a Right of First Refusal or Right of Co-Sale
pursuant to this Section 3.4 shall be final and irrevocable.

                    (e)  For purposes of this Section 3.4, the maximum number of
Securities each Section 3.4 Seller may sell to the Third Party Purchaser (or the
Section 3.4 Purchasers, as the case may be) shall be equal to the product of the
total number of Offered Securities multiplied by a fraction, the numerator of
which shall be the total number of Securities owned by such Section 3.4 Seller
and the denominator of which shall be the total number of Securities owned by
the Transferor and all of the Section 3.4 Sellers.

                                                                           7

                    (f)  If the Section 3.4 Purchasers collectively have
exercised their Rights of First Refusal with respect to all of the Offered
Securities, then the closing of such sale and purchase shall take place promptly
after the final allocation with respect to such Offered Securities has been
determined, at the principal offices of the Company or such other place and time
as the relevant parties may agree.  If the Section 3.4 Purchasers collectively
have not exercised their Rights of First Refusal with respect to all of the
Offered Securities, then the Transferor and the Section 3.4 Sellers shall have
120 calendar days after the end of the Last Chance Period to make the Transfer
of the Offered Securities to the Third Party Purchaser at the price and upon the
terms specified in the Transferor Notice.  The total number of Securities
permitted to be Transferred to the Third Party Purchaser by the Transferor
hereunder shall be equal to the total number of Offered Securities less that
number of Securities offered to the Third Party Purchaser by the Section 3.4
Sellers pursuant to this Section 3.4.  In the event the Transferor and the
Section 3.4 Sellers do not Transfer such Securities to the Third Party Purchaser
within such 120-day period, the Transferor shall not thereafter make a Transfer
of such Offered Securities without again complying with the Right of First Offer
and Right of Co-Sale provisions in this Section 3.4.

                    (g)  The exercise or non-exercise of the Right of First
Refusal and the Right of Co-Sale by a Section 3.4 Rightholder with respect to a
Transfer of Securities by a Transferor shall not affect such Section 3.4
Rightholder's Right of First Refusal or Right of Co-Sale with respect to
subsequent Transfers of Securities.

                    (h)  A change in the beneficial ownership of any Shareholder
or any Person that controls a Shareholder shall not constitute a Transfer of
Securities that causes the Right of First Refusal and the Right of Co-Sale to
arise hereunder so long as such Shareholder's ownership interest in the Company
does not constitute the primary asset of such Shareholder or other Person in
respect of which such change in beneficial ownership occurs.

                    (i)  Any Section 3.4 Rightholder may assign its Right of
First Refusal or Right of Co-Sale hereunder to (i) any other Section 3.4
Rightholder, (ii) any Affiliate of such Section 3.4 Rightholder or (iii) a
nominee of such Section 3.4 Rightholder, insofar as such Section 3.4 Rightholder
is unable to reap the benefit of this Section 3.4 because the Transfer of
Securities to such Section 3.4 Rightholder as provided herein is not permitted
by any governmental authority or is not possible for any other reason.

               3.5  VETO RIGHTS.  If a Shareholder proposes to Transfer
Securities to a Third Party Purchaser that is engaged in a business directly
competing with that of the Company at the time of the proposed Transfer, non-
Transferring Shareholders holding in the aggregate at least 25% of the issued
Shares shall each have the right to prohibit such Transfer, notwithstanding
compliance by the Transferor with Section 3.4.  For the avoidance of doubt, this
provision shall not apply to Transfers made pursuant to Section 3.3.1.

               3.6  IWC RIGHT OF FREE SALE.  Notwithstanding anything to the
contrary contained herein and in addition to its rights under Section 3.3, IWC
shall have the right, exercisable once at any time prior to November 7, 1997, to
Transfer any or all of its Securities to 

<PAGE>

                                                                           8

any Person and such Transfer shall not be subject to the Right of First 
Refusal or Right of Co-Sale hereunder.

               3.7  STHL RIGHT OF FREE SALE.  Notwithstanding anything to the
contrary contained herein, STHL shall have the right, exercisable once at any
time after the date of this Agreement, to Transfer up to an aggregate of 5%
(determined as of the date of the exercise) of its Securities to any Person and
such Transfer shall not be subject to the Right of First Refusal or Right of Co-
Sale hereunder.

               3.8  VANGUARD RIGHT OF FREE SALE.  Notwithstanding anything to
the contrary contained herein and in addition to its rights under Section 3.3,
Vanguard shall have the right, exercisable once at any time prior to November 7,
1997, to Transfer any or all of its Securities to any Person and such Transfer
shall not be subject to the Right of First Refusal or Right of Co-Sale
hereunder.

          4.   RIGHT OF FIRST OFFER.  The Company hereby grants to each
Shareholder a right of first offer ("Right of First Offer") to subscribe for
such Shareholder's pro-rata share of any New Securities (as defined in Section
4(e) below) that the Company may from time to time propose to issue, and the
provisions of this Article 4 shall apply to such issuances other than issuances
pursuant to Article 7.

               (a)  In the event that the Company proposes to undertake an
issuance of New Securities, the Company shall give written notice (the "Company
Notice") of its intention to so issue such New Securities to each Shareholder. 
The Company Notice shall include the type and number of such New Securities, the
price and the general terms upon which such New Securities are proposed to be
issued, the number of such New Securities for which each Shareholder is entitled
to subscribe pursuant to this Article 4 and the identity of the Person(s) to
whom such New Securities are proposed to be issued (the "Proposed Acquirers").

               (b)  Each Shareholder shall have 21 calendar days after the
receipt of the Company Notice to agree irrevocably to subscribe for up to its
pro-rata share of such New Securities for the price and upon the general terms
specified in the Company Notice by giving written notice to the Company and
stating therein the number of New Securities for which such Shareholder shall
subscribe.  If any Shareholder fails to exercise or waives its Right of First
Offer hereunder (a "Non-Exercising Shareholder"), the Company shall give notice
to all Shareholders who do exercise their Right of First Offer (the "Exercising
Shareholders") of such failure or waiver.

               (c)  Each Exercising Shareholder shall have a right of over
allotment to subscribe for up to its pro-rata portion of any New Securities not
subscribed for by a Non-Exercising Shareholder hereunder.  Each Exercising
Shareholder may exercise irrevocably such right of over allotment by giving
written notice to the Company within seven calendar days of receipt of the
notice of non-exercise or waiver from the Company described in clause (b) above
and stating therein the number of New Securities for which such Exercising
Shareholder shall subscribe.  Upon exercises of the Right of First Offer
hereunder in connection with any proposed

                                                                           9

issuance of New Securities, the Company shall simultaneously issue such New 
Securities pursuant to such exercises at such time and place as the Company 
shall determine.  Any exercise by any Shareholder of a right of subscription 
pursuant to this Article 4 shall be final and irrevocable.

               (d)  In the event the Shareholders waive or fail to exercise in
full the Right of First Offer set forth in clauses (b) and (c) of this Article 4
with respect to all of the New Securities within the above-mentioned time
periods, then the Company shall have 120 calendar days thereafter to sell any
New Securities with respect to which the Shareholders did not exercise their
Right of First Offer at a price and upon general terms no more favorable to the
Proposed Acquirers than those specified in the Company Notice.  In the event the
Company does not sell the New Securities within such 120-day period, the Company
shall not thereafter issue or sell such New Securities without first offering
such New Securities to the Shareholders in accordance with this Article 4.

               (e)  For the purposes of this Article 4, the term "New
Securities" shall mean any Securities, whether now authorized or authorized in
the future, that are offered for subscription or sale by the Company.

               (f)  The exercise or non-exercise of the Right of First Offer by
a Shareholder hereunder with respect to an issuance of New Securities shall not
affect such Shareholder's Right of First Offer with respect to subsequent
issuances of New Securities.

               (g)  Any Proposed Acquirer to whom New Securities are issued
pursuant to this Article 4 shall become a party to and shall be bound by the
restrictions on Transfer and the other restrictions and obligations set forth in
this Agreement to the same extent and with the same force and effect as if such
person were an original signatory hereto.  Each Proposed Acquirer shall, as a
condition to subscribing for such New Securities, execute a Deed of Adherence
substantially in the form of Exhibit A upon or before the consummation of the
issuance of such New Securities.

          5.   MANAGEMENT.

               5.1  GENERAL.  From and after the date hereof, each Shareholder
shall vote its Shares at any ordinary general meeting or extraordinary general
meeting of Shareholders (a "Shareholders' Meeting") or in any written resolution
executed in lieu of such a meeting of Shareholders (a "Written Resolution"), and
shall take all other actions necessary, to give effect to the provisions of this
Agreement (including, without limitation, Section 5.3.2) and to ensure that the
Charter Documents do not, at any time hereafter, conflict in any respect with
the provisions of this Agreement.  In addition, each Shareholder shall vote its
Shares at any Shareholders' Meeting, or act by Written Resolution with respect
to such Shares, upon any matter submitted for action by the Shareholders or with
respect to which such Shareholder may vote or act by Written Resolution, in

Charter Documents.

               5.2  SHAREHOLDER VOTES. The following matters in relation to the

                    (e)  settlement, waiver or discontinuance of any litigation
or arbitration proceedings involving a claim exceeding the equivalent of

initiating any litigation or arbitration proceedings involving a claim exceeding
the equivalent of US$500,000;

Company or any Subsidiary with any other entity;

Subsidiary;

                    (h)  the acquisition or disposition of any business or
company by the Company or any Subsidiary; and

by the Company or any Subsidiary other than in the ordinary course of business.

               Notwithstanding the provisions of Section 5.2(e), where
litigation or arbitration proceedings are or are proposed to be brought by or
against the Company against or by any Shareholder or any Affiliate of any
Shareholder, irrespective of the amount involved, such Shareholder, and the
Directors appointed by such Shareholder to the Board, shall have no vote in
determining whether such litigation or arbitration proceedings shall be
initiated, settled or discontinued or how the same shall be conducted.

                                                                           11

Board of, (i) five nominees of IWC and (ii) five nominees of STHL.  The parties
hereto agree that if IWC no longer has the right to nominate any Director on the

such Director.  Otherwise, no Shareholder shall vote for the removal of a
Director.

Chairman of the Board shall be nominated by STHL.  The Chairman of the Board

event, until which he is by the terms of his appointment to hold office or if 
the appointor in writing terminates the appointment or if the appointor 
himself ceases for any reason to hold office as a Director.  An appointment 
of an alternate Director shall not prejudice the right of the appointor to 
receive notices of and to attend and vote at meetings of the Board, and the 
powers of the alternate Director shall automatically be suspended during such 
time as the Director appointing him is himself present in person at a meeting 
of the Board.

Director, within 30 days after the end of each month, a monthly operating report

not less than 60 days prior to the commencement of the six-month period in
question.

               6.13 BANK ACCOUNTS.  The parties shall procure that the bank
account or bank accounts opened in the name of the Company with The Hongkong and
Shanghai Banking Corporation Limited, or such other bank or banks as may be
determined by the Board, are maintained.  Such account or accounts shall be
operated as the Board shall resolve from time to time.  All payments to or by
the Company shall be paid into or withdrawn from such account or accounts.

          7.   FUNDING.

               7.14 ADDITIONAL CAPITAL CONTRIBUTIONS.  The Shareholders shall
make capital contributions to the Company as contemplated by any business plan
approved by the Board in accordance with Section 5.5.  Such capital
contributions shall be made in proportion to each Shareholder's then equity
interest in the Company and according to a schedule determined by the Board and
shall be in the form of additional equity capital contributions or shareholder
loans.  For the purposes of this Article 7, as of the date hereof; (i) STHL
shall be deemed to have contributed US$14,575,000; (ii) IWC shall be deemed to
have contributed US$11,000,000; and (iii) Vanguard shall be deemed to have
contributed US$1,925,000, in each case, to the capital of the Company.

               7.15 FAILURE TO MAKE CAPITAL CONTRIBUTION.  If the Board shall
require that the Shareholders make capital contributions to the Company (a
"Capital Call") in the form of equity capital contributions and if any
Shareholder fails to contribute in full the capital 

<PAGE>

                                                                           16

required to be contributed by such Shareholder pursuant to such Capital Call 
(each, a "Required Contribution") within the time specified by the Board (the 
"Capital Deadline"), then the percentage equity ownership interest of such 
defaulting Shareholder (a "Defaulting Shareholder") in the Company shall be 
reduced as provided in this Article 7, and the percentage equity ownership 
interests of each Shareholder who contributes at least its Required 
Contribution (each, a "Non-defaulting Shareholder") shall be increased as 
provided in this Article 7.  If the Board shall make a Capital Call from the 
Shareholders in the form of shareholder loans, and if any Shareholder fails 
to contribute in full its Required Contribution pursuant to such Capital 
Call, then such Capital Call shall automatically be converted into a Capital 
Call for equity capital contributions, and the percentage equity ownership 
interest of such Defaulting Shareholder in the Company shall be reduced as 
provided in this Article 7, and the percentage equity ownership interests of 
each Non-defaulting Shareholder shall be increased as provided in this 
Article 7.

               7.16 MAKING UP THE AMOUNTS OF DEFAULT.  For each Capital Call,
each Non-defaulting Shareholder shall have the right to contribute additional
capital to the Company to make up for the aggregate of all of the Defaulting
Shareholders' "Amounts of Default" (as defined in Section 7.5 below).  Each Non-
defaulting Shareholder that elects to exercise such right (each, a
"Participating Shareholder") shall be permitted to contribute additional capital
in an amount up to its pro-rata share of the aggregate of all of the Defaulting
Shareholders' Amounts of Default, which pro-rata share shall be based upon the
proportion (calculated as of immediately prior to the Capital Call) such
Participating Shareholder's equity interest in the Company bears to the
aggregate equity interest in the Company of all Participating Shareholders.  For
the purposes of this Article 7, any amounts contributed pursuant to this Section
7.3 shall be deemed to have been contributed prior to the Capital Deadline.

               7.17 SHAREHOLDERS' EQUITY INTERESTS.  Each Shareholder's equity
interest in the Company shall be increased or decreased (as applicable) to the
percentage equal to such Shareholder's Capital Percentage.

               7.18 DEFINITIONS.

                    (a)  "Capital Percentage" shall mean, for a Shareholder,
after any Capital Call, the product of 100% times a fraction, the numerator of
which shall be the total of all amounts contributed as capital to the Company
(including any amounts deemed contributed pursuant to Section 7.3) by such
Shareholder (less any such amounts returned by the Company to such Shareholder)
as of immediately after the Capital Deadline, and the denominator of which shall
be the total of all amounts contributed as capital to the Company  (including
any amounts deemed contributed pursuant to Section 7.3) by all Shareholders
(less any  amounts returned by the Company to all Shareholders) as of
immediately after the Capital Deadline.

                    (b)  "Amount of Default" shall mean, for a Defaulting
Shareholder, such Defaulting Shareholder's Required Contribution LESS the amount
of capital

<PAGE>

                                                                           17

actually contributed to the Company by such Defaulting Shareholder prior to 
the Capital Deadline pursuant to the Capital Call requiring such Required 
Contribution.

          8.   MANAGEMENT OPTIONS.  The parties agree that options to purchase
up to an aggregate number of Shares that equals 5% of the authorized share
capital of the Company immediately after the "First Closing" under the
Subscription Agreement (taking into account the amendments to the Memorandum and
Articles of Association of the Company contemplated by the Subscription
Agreement) at a price per Share to be agreed to by the Board may be issued upon
the unanimous decision of the Board to members of senior management of the

promptly amended, to the extent permitted by applicable law, in order to conform
with this Agreement.

               16.25 SEVERABILITY.  In the event any provision hereof is held

               16.26 ENTIRE AGREEMENT.  This Agreement, together with the other
agreements referred to herein, reflects the entire agreement among the parties

only by a written instrument signed by all of the parties hereto or, in the case
of a waiver, by the party waiving compliance.  No delay on the part of any party
in exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any waiver on the part of any party of any such right, power
or privilege, nor any single or partial exercise of any such right, power or

               16.29 CONSENT TO SPECIFIC PERFORMANCE.  The parties hereto
declare that it is impossible to measure in money the damages that would be
suffered by a party by reason of the failure by any other party to perform any
of the obligations hereunder.  Therefore, if any party shall institute any
action or proceeding to enforce the provisions hereof, any party against whom
such action or proceeding is brought hereby waives any claim or defense therein
that the other party has an adequate remedy at law.

               16.30 ASSIGNMENT; BINDING ON TRANSFEREE.  The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and permitted transferees from and after the

               16.32 ARBITRATION.  

                     (a) Any dispute or claim arising out of or relating to this
Agreement, or the breach, termination or invalidity hereof, shall be finally
settled by arbitration under the Rules of Conciliation and Arbitration of the
International Chamber of Commerce (the "Rules") as are currently in force and as
may be amended by the rest of this Section 16.11.  For the purpose of such
arbitration, there shall be one or more arbitrators appointed in accordance with
the Rules (such single arbitrator or board of arbitrators, as the case may be,
are referred to below as the "Arbitration Board").  The place of arbitration
shall be Hong Kong.  All arbitration proceedings shall be conducted in the
English language.  The arbitrators shall decide any such dispute or claim
strictly in accordance with the governing law specified in Section 16.10 of this
Agreement.  Judgment upon any arbitral award rendered hereunder may be entered
in any court having jurisdiction, or application may be made to such court for a
judicial acceptance of the award and an order of enforcement, as the case may
be.

                     (b) Each party shall cooperate in good faith to expedite
(to the maximum extent practicable) the conduct of any arbitral proceedings
commenced under this Agreement.

                     (c) The costs and expenses of the arbitration, including,
without limitation, the fees of the Arbitration Board, shall be borne equally by
each party to the dispute or claim, and each party shall pay its own fees,
disbursement and other charges of its counsel.

                     (d) Any award made by the Arbitration Board shall be final
and binding on the parties hereto.  The parties expressly agree to waive the
applicability of any laws and regulations that would otherwise give the right to
appeal the decisions of the Arbitration Board so that there shall be no appeal
to any court of law for the award of the Arbitration Board, and a party shall
not challenge or resist the enforcement action taken by another party in whose
favor the award of the Arbitration Board was given.

               16.33 SHAREHOLDER OBLIGATIONS; FURTHER ASSURANCES.  The parties
hereto shall comply with the provisions of this Agreement in relation to their
investment in the Company and in transacting business with the Company and shall
exercise their respective rights and powers in accordance with and so as to give
effect to this Agreement.  Each of the parties shall execute such documents and
other papers and take such further actions as may be reasonably required or
desirable to carry out the provisions hereof and the transactions contemplated
hereby.
               16.34 COUNTERPARTS.  This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original, but all of which

          WHEREAS, Vanguard China, Inc. ("Vanguard"), STHL and SDL have entered 
into a Stock Purchase Agreement (the "Stock Purchase Agreement") dated as of

          WHEREAS, IWC, STHL, SDL and Vanguard intend to enter into an Amended
and Restated Shareholders' Agreement (the "Shareholders' Agreement") dated as of
the date hereof, amending and restating the Shareholders' Agreement entered into
by SDL, STHL and IWC on November 7, 1996, to regulate certain matters relating
to SDL.

          WHEREAS, the parties hereto wish to amend and restate the Original
Noncompetition Agreement to be consistent with the Shareholders' Agreement.

          NOW THEREFORE, in consideration of the foregoing and of the mutual

telephone services, or the provision of technical or other services or the
licensing of technology or intellectual property (including, without limitation,
proprietary information, trademarks or patents) in support of mobile telephone

of mobile telephone roaming services that may be carried out by P Plus
Communications Limited, (i) for a Restricted Party's own account, (ii) by
rendering services to any Person engaged in the provision of mobile telephone
services, or the provision of technical or other services or the licensing of

information, trademarks or patents) in support of mobile telephone services, but

may be withheld by IWC in its sole discretion), directly or indirectly engage in
a Restricted Business which is in 

<PAGE>

                                                                               3

direct competition with any Restricted Business engaged in or operated by SDL

Affiliates comply with the terms of this Agreement and shall, upon the 
request of the other party, cause its Affiliates to execute a deed of 
adherence to this Agreement in such form as the other party may reasonably 
request.

          3.   CORPORATE OPPORTUNITIES.  If a Restricted Party offers to the
shareholders of SDL and the board of directors of SDL (the "SDL Board") for
consideration the opportunity for SDL to make an investment in a Restricted
Business that is not in direct competition with any business theretofore engaged
in or operated by SDL, but the shareholders of SDL and the SDL Board fail to
adopt a resolution approving and authorizing SDL's investment in such Restricted
Business or fail to respond to the Restricted Party within 14 days after the
Restricted Party has notified the shareholders of SDL and the SDL Board of this
investment opportunity, then, (i) in the case of an opportunity brought to SDL
by IWC, notwithstanding that IWC and its permitted transferees in their capacity
as shareholders of SDL or that the nominees of IWC and its permitted transferees
on the SDL Board, shall in each case have voted in favor of SDL's investment in
such opportunity, IWC, as the Restricted Party, shall have the right to invest
directly or indirectly in such Restricted Business, and (ii) in the case of an
opportunity brought to SDL by STHL, notwithstanding that STHL and its permitted
transferees in their capacity as shareholders of SDL or that the nominees of
STHL and its permitted transferees on the SDL Board, shall in each case have
voted in favor of SDL's investment in such opportunity, STHL as the Restricted
Party, shall have the right to invest directly or indirectly in such Restricted 
Business. 
          
          4.   TERM AND TERMINATION.  This Agreement shall remain in effect
until the earliest of (i) the date that is 10 years after the date hereof, (ii)
the date STHL or IWC ceases to hold shares in SDL, (iii) the dissolution or
winding up of SDL, (iv) the termination or expiration of the Shareholders'
Agreement and (v) the insolvency of SDL, the commission of any act of bankruptcy
by SDL, or the commencement of proceedings with respect to SDL for relief under 
bankruptcy or insolvency laws or laws relating to the relief of debtors,
reorganizations, arrangements, compositions or extensions.   

          5.   RIGHTS AND REMEDIES UPON BREACH.  If any Restricted Party
breaches, or threatens to commit a breach of, any of the provisions of Section 2
(the "Restrictive Covenant"), each non-defaulting Restricted Party shall have
the following rights and remedies, each of which rights and remedies shall be
independent of the others and severally enforceable and each of which is in
addition to, and not in lieu of, any other rights and remedies available to such
non-defaulting Restricted Party under law or in equity:

                (a) SPECIFIC PERFORMANCE.  The right and remedy to have the
Restrictive Covenant specifically enforced by any court of competent
jurisdiction, it being agreed that any breach or threatened breach of the
Restrictive Covenant would cause 

<PAGE>
                                                                               4

irreparable injury to such non-defaulting Restricted Party and that money 
damages would not provide an adequate remedy to such non-defaulting 
Restricted Party.  In seeking such injunctive relief, a non-defaulting 
Restricted Party shall not be obligated to secure any bond or other security.

               (b)  ACCOUNTING.  The right and remedy to require the Restricted
Party to account for and pay over to the non-defaulting Restricted Parties, all
compensation, profits, monies, accruals, increments or other benefits derived or
received by such Restricted Party as the result of any transactions by such
Restricted Party constituting a breach of the Restrictive Covenant.

          6.   SEVERABILITY.  The Restricted Parties acknowledge and agree that
the Restrictive Covenant is reasonable and valid in geographical and temporal
scope and in all other respects.  If any court determines that the Restrictive
Covenant, or any part thereof, is invalid or unenforceable, the remainder of the
Restrictive Covenant shall not thereby be affected and shall be given full
effect without regard to the invalid portions.  If any court determines that the
Restrictive Covenant, or any part thereof, is unenforceable because of the
duration or geographic scope of such provision, such court shall have the power
to reduce the duration or scope of such provision, as the case may be, and, in
its reduced form, such provision shall then be enforceable.

          7.   ENFORCEABILITY IN JURISDICTIONS.  The Restricted Parties intend
to and hereby confer jurisdiction to enforce the Restrictive Covenant upon the
courts of any jurisdiction within the geographical scope of the Restrictive
Covenant.  If the courts of any one or more of such jurisdictions hold the
Restrictive Covenant unenforceable by reason of the breadth of such scope or
otherwise, it is the intention of the Restricted Parties that such determination
shall not bar or in any way affect a non-defaulting Restricted Party's right to
the relief provided above in the courts of any other jurisdiction within the
geographical scope of the Restrictive Covenant, as to breaches of the
Restrictive Covenant in such other respective jurisdictions, the Restrictive
Covenant as it relates to each jurisdiction being, for this purpose, severable
into diverse and independent covenants.

          8.   WAIVER.  The failure of a non-defaulting Restricted Party to
insist in any one or more instances upon performance of any of the provisions of
this Agreement or to take advantage of any such non-defaulting Restricted
Party's rights hereunder shall not be construed as a waiver of any such
provisions or the relinquishment of any such rights, and the same shall continue
and remain in full force and effect.  No single or partial exercise by any party
of any right or remedy shall preclude other or future exercise thereof or the
exercise of any other right or remedy.  Waiver by any party of any breach of any
provision of this Agreement shall not constitute or be construed as a continuing
waiver or as a waiver of any other breach of any other provision of this
Agreement.

     arbitration under the Rules of Conciliation and Arbitration of the

     specified in Section 9(b) of this Agreement.  Judgment upon any arbitral 
     award rendered hereunder may be entered in any court having jurisdiction,

                    (iv)   Any award made by the Arbitration Board shall be
     final and binding on the parties hereto.  The parties expressly agree to
     waive the applicability of any laws and regulations that would otherwise
     give the right to appeal the decisions of the Arbitration Board so that
     there shall be no appeal to any court of law for the award of the
     Arbitration Board, and a party shall not challenge or resist the
     enforcement action taken by another party in whose favor the award of the
     Arbitration Board was given.

               (d)  ASSIGNMENT AND SUCCESSION.  STHL may not assign this

                                    AGREEMENT



     THIS AGREEMENT, made and entered into as of the 5th day of May, 1997
between Vanguard Cellular Financial Corp. ("Vanguard") and International
Wireless Communications Holdings, Inc. ("IWCH").

     WHEREAS, Vanguard, through an indirect subsidiary, owns approximately
36.11% of the issued and outstanding common stock of IWCH on an as converted
basis and certain warrants to purchase additional shares; and

     WHEREAS, the Chairman of the Board of Vanguard's parent company, Vanguard
Cellular Systems, Inc., also serves as Chairman of the Board of IWCH and has
been instrumental in the development of IWCH; and

     WHEREAS, certain other employees of Vanguard have performed valuable
services for or on behalf of IWCH in its formative stages; and

     WHEREAS, Vanguard and IWCH desire to reward the Vanguard employees for
their services to IWCH and to provide incentive for their continuing efforts
without causing dilution to other stockholders of IWCH; 

     NOW, THEREFORE, the parties agree as follows:

     1.   EXCHANGE OF WARRANTS.  Vanguard, through its wholly owned subsidiary,
Vanguard Cellular Operating Corp. ("Operating Corp,"), owns certain Warrants to
purchase common stock of IWCH, which Warrants are listed on SCHEDULE I to this
Agreement.  Vanguard agrees to cause Operating Corp. to surrender as of the date
hereof, such Warrants to IWCH for cancellation in exchange for two new Warrants
that will be issued to Operating Corp., one to acquire 554,750 shares of IWCH
common stock ("Common Stock") at a purchase price of $9.375 per share (the
"$9.375 Warrant") pursuant to Warrant Agreement, a form of which is attached
hereto as EXHIBIT A, and one for 249,970 shares at $0.25 per share (the "$0.25
Warrant") pursuant to a Warrant Agreement, a form of which is attached hereto as
EXHIBIT B.  As of the date hereof, IWCH will grant to Haynes G. Griffin an
incentive stock option to purchase 53,330 shares of Common Stock, which option
shall be in the form attached hereto as EXHIBIT C, and will grant nonstatutory
options to purchase an aggregate of 501,420 shares of Common Stock to the
individuals and in the amounts set forth on SCHEDULE II hereto, each of which
shall be in the form attached hereto as EXHIBIT D.  The options will be granted
subject any requisite approval or waiver of the holders of IWCH's capital stock
within one year of the date of grant ("Stockholder Approval").

<PAGE>

     2.   SURRENDER OF WARRANTS.  Vanguard agrees to surrender to IWCH for
cancellation its $9.375 Warrant, subject to Stockholder Approval.

     3.   GUARANTY.  The parties acknowledge that, as a result of the
transactions contemplated by this Agreement, IWCH is less likely to receive
funds upon exercise of Warrants than it otherwise would have, and, as a result,
its short-term cash flow will be adversely affected.  Although IWCH plans to
alleviate its working capital shortage by arranging debt financing or effecting
an initial public offering of its common stock it may require interim financing
as a result of not receiving such funds.  Therefore, Vanguard agrees to assist
IWCH in arranging such interim financing by guaranteeing up to an aggregate of
$3,200,000.00 of indebtedness incurred by IWCH or its wholly owned subsidiaries,
until such time as IWCH receives at least $3,200,000 in alternative debt
financing or consummates an initial public offering providing it with at least
$3,200,000 in net proceeds, but in no event shall such guaranty remain
outstanding later than February 3, 1999.  The guaranty shall be in substantially
the form attached hereto as Exhibit E, or in such other form as shall be
reasonably requested by the lender and be reasonably satisfactory to Vanguard,
together with other customary terms and conditions as are reasonably
satisfactory to Vanguard and IWCH, and will be made available upon receipt of
Stockholder Approval and Bank Approval.

     4.   REPRESENTATIONS AND WARRANTIES.

          4.1    IWCH represents and warrants to Vanguard that:

          a.     ORGANIZATION, GOOD STANDING, AND QUALIFICATION.  IWCH 
    is a corporation duly organized, validly existing, and in good standing 
    under the laws of the State of Delaware and has all requisite corporate 
    power and authority to carry on its business as now conducted and as 
    proposed to be conducted.  IWCH is duly qualified to transact business 
    and is in good standing in each jurisdiction in which the failure so to 
    qualify would have a material adverse effect on its business or 
    properties.
    
          b.     AUTHORIZATION.  All corporate action on the part of 
    IWCH, its officers, directors, and shareholders necessary for the 
    authorization, execution, and delivery of this Agreement and the 
    performance of all obligations of IWCH hereunder has been taken or will 
    be taken prior to the Closing.
    
          c.     COMPLIANCE WITH OTHER INSTRUMENTS.  Neither the 
    execution and delivery by IWCH of this Agreement or any agreement or 
    instrument attached hereto, nor compliance by IWCH with the terms and 
    provisions hereof and thereof, including without limitation, the 
    consummation of the transactions contemplated hereby, will violate any 
    statute, regulation or ordinance of any governmental authority, or 
    conflict with or result in the breach of any term, condition, or 
    provision of the Certificate of Incorporation or the Bylaws of IWCH or 
    of any agreement, deed, contract, mortgage, indenture, writ, order,

    its assets are or may be bound, or constitute a default (or an event 
    which, with the lapse of time or the giving of notice, or both, would 
    constitute a default) thereunder, where such violation, conflict and/or 
    default could have a material adverse effect on (i) the consummation of

    the Agreements and consummation at the closing of the transactions 
    contemplated by the Agreements have been obtained, and are effective.

       4.2      Vanguard represents and warrants to IWCH that:

    standing under the laws of the State of Delaware and has all requisite 
    corporate power and authority to carry on its  business as now conducted 
    and as proposed to be conducted.  Vanguard is duly qualified to transact 
    business and is in good standing in each jurisdiction in which the 
    failure so to qualify would have a material adverse effect on its 
    business or properties.
    
         b.     AUTHORIZATION.  All corporate action on the part of 
    Vanguard, its officers, directors, and shareholders necessary for the 
    authorization, execution, and delivery of this Agreement and the 
    performance of all obligations of Vanguard hereunder has been taken or 
    will be taken prior to Closing.

          c.     COMPLIANCE WITH OTHER INSTRUMENTS.  Neither the 
    execution and delivery of this Agreement by Vanguard, nor compliance by 
    Vanguard with the terms and provisions hereof, including without 
    limitation, the consummation of the transactions contemplated hereby, 
    will violate any statute, regulation, or ordinance of any governmental 
    authority, or conflict with or result in the breach of any term, 
    condition, or provision of the Articles of Incorporation or the Bylaws 
    of Vanguard or of any agreement, deed, contract, mortgage, indenture, 
    writ, order, decree, legal obligation or instrument to which Vanguard is 
    a party or by which it or any of its assets are or may be bound, or 
    constitute a default (or an event which, with the lapse of time or the 
    giving of notice, or both, would constitute a default) thereunder, where 
    such violation, conflict and/or default could have a material adverse 
    effect on (i) the consummation of the transactions contemplated by this 
    Agreement, or (ii) the results of operations, financial condition or 
    assets of Vanguard.

          d.     CONSENTS AND APPROVALS.  All consents, approvals,

    representation to the effect of Exhibit F hereof.

5.    REGISTRATION RIGHTS.

          a.     Shares of Common Stock issued or issuable upon exercise 
    of options granted hereunder (collectively, "Options") to Haynes G. 
    Griffin, Van Snowdon and John Russell Dunn (collectively, "IWCH Service 
    Providers") shall be registered on an effective registration statement 
    on Form S-8 (or any successor form of registration statement primarily 
    relating to the sale of securities to employees of or consultants to the 
    Company pursuant to a stock option, stock purchase or similar plan) 
    under the Securities Act of 1933, as amended ("Act"), whenever a 
    registration statement of Form S-8 (or any such successor form) shall be 
    effective covering shares of Common Stock issued or issuable upon 
    exercise of options granted to the executive officer of IWCH.

          b.     If the Company shall receive at any time after the 
    first anniversary of the date upon which Options are granted to persons 
    other than IWCH Service Providers (the "Other Persons"), a written 
    request from holders of a majority of the shares of Common Stock or 
    other securities issued or issuable upon the exercise of such Options 
    (the "Registrable Securities"), that the Company file a registration 
    statement under the Act covering the registration of at least 25% of the 
    Registrable Securities, then the Company shall effect as soon as 
    practicable, and in any event within sixty (60) days of the receipt of 
    such request, the registration under the Act of all Registrable 
    Securities.  The company shall maintain the effectiveness of any 
    registration statement filed and declared effective pursuant to Section 
    5(b) for a period of at least ninety (90) days.  Notwithstanding the 
    foregoing, the Company shall not be obligated to effect, or take any 
    action to effect, any registration pursuant to this Section 5(b):

              i.     During any period in which the Registrable 
    Securities may be publicly resold pursuant to Rule 144 under the Act (or 
    any successor rule), regardless of whether such resale is subject to the 
    volume limitations of such Rule or is permitted only if the Registrable 
    Securities must be exercised on a net issue basis pursuant to Section 5 
    of the applicable Option. [Vanguard acknowledges that, pursuant to 
    Rule 144(d)(3)(ii) as currently in effect, Common Stock acquired upon 
    exercise of an Option on a net issue basis will be deemed to be acquired 
    at the time the option was acquired];

             ii.     More than once during any eighteen (18) month period; or

                                        4

<PAGE>

            iii.     During any period when the Company is ineligible to 
    use a registration statement o Form S-3 (or any successor form with 
    comparable disclosure requirements) for resales of Registrable 
    Securities.

          c.     The Company shall take all customary and reasonable 
    actions necessary to effect the registration rights granted hereunder.

          d.     Notwithstanding this Section 5, no Registrable 
    Securities may be publicly resold during any period when an executive 
    officer of IWCH is prohibited from publicly reselling Common Stock under 
    applicable insider trading policies and procedures of IWCH.

          e.     All expenses (other than underwriting discounts and 
    commissions, if applicable) incurred in connection with effecting up to 
    two (2) registrations pursuant to Section 5(b) hereof shall be paid by 
    the Company (including fees and disbursements of a single counsel for 
    the selling stockholders, provided such counsel shall also be counsel 
    for the Company in connection with such registrations).

          f.     Each holder of an Option agrees for himself (and any 
    transferee of such Option) that, during the period of duration specified 
    by the Company following the effective date of a registration of the 
    Company filed under the Act, such person shall not, to the extent 
    requested by the Company, directly or indirectly sell, offer to sell, 
    contract to sell (including, without limitation, any short sale), grant 
    and any option to purchase or otherwise transfer or dispose of (other 
    than to donees who agree to be similarly bound) any securities of IWCH 
    (or any interest therein) held by it by any time during such period, 
    except Common Stock included in such registration statement; provided, 
    however, that such agreement shall be applicable only if all officers 
    and directors of IWCH hereunto are bound by similar agreements of at 
    least the same period of duration.

    6.    OPINIONS OF COUNSEL.  Vanguard will cause its legal counsel to 
deliver to IWCH its opinion in substantially the form of EXHIBIT F 
hereto, and IWCH will cause its counsel to deliver to Vanguard its 
opinion in substantially the form of EXHIBIT G hereto, dated as of the 
date hereof.

    7.   GOVERNING LAW.  This Agreement shall be governed by and 
construed and enforced in accordance with the laws of the State of 
Delaware, without giving effect to any choice of law or conflict 
provision or rule that would cause the laws of any other jurisdiction to 
be applied.
    
    8.   SUCCESSORS AND ASSIGNS.  This Agreement may not be assigned or 
otherwise transferred by either party without the written consent of the 
other.  This Agreement shall be binding upon and inure to the benefit to 
the parties hereto and their respective successors and assigns.

                                        5

    9.   AMENDMENTS.  No amendment, modification or discharge of this 
Agreement, and no waiver of any condition or the breach of any 
provision, term, covenant, representation or warranty hereunder shall be 
valid or binding unless set forth in writing and duly exercised by the 
party against whom enforcement of the Agreement, modification, discharge 
or waiver is sought.

    10.  ENTIRE AGREEMENT.  This Agreement, together with the documents 
contemplated hereby and attached hereto, constitutes the entire 
agreement among the parties with respect to the subject matter hereof 
and supersedes and cancels any and all prior agreements and 
understandings, both written and oral, among them relating to the 
subject matter hereof.   

    11.  COUNTERPARTS.  Counterparts of this Agreement may be executed in 
several counterparts, each of which shall be deemed an original and all 
of which shall together constitute one and the same instrument.

          4.   Net Issue Exercise.  

              (a)    In lieu of exercising this Warrant, Holder may elect to 
receive shares equal to the value of this Warrant (or the portion thereof 
being canceled) by surrender of this Warrant at the principal office of the 
Company together with notice of such election in which event the Company 
shall issue to Holder a number of shares of Equity Securities computed using 
the following formula:

                                 X = (Y)(A-B)
                                 ------------
                                       A

       Where   X -  The number of shares of Equity Securities to be issued 
                    to Holder.
               Y -  The number of shares of Warrant Shares to be surrendered.
               A -  The fair market value of one share of the Equity Securities
                    to be issued upon exercise of this Warrant.
               B -  Exercise Price (as adjusted to the date of such 
                    calculations).

              (b)   For purposes of this Section, the Board of Directors of 
the Company shall determine the fair market value in its good faith.  

          5.   CERTIFICATES FOR WARRANT SHARES.  Upon the exercise of the 
purchase rights evidenced by this Warrant, one or more certificates for the 
number of Warrant Shares so purchased shall be issued as soon as practicable 
thereafter, and in any event within thirty (30) days of the delivery of the 
subscription notice.

          6.   RESERVATION OF WARRANT SHARES.  The Company covenants that it 
will at all times keep available such number of authorized shares of its 
Equity Securities issuable upon exercise of this Warrant free from all 
preemptive rights with respect thereto, which will be sufficient to permit 
the exercise of this Warrant for the full number of Warrant Shares specified 
herein.  The Company further covenants that such Warrant Shares, when issued 
pursuant to the exercise of this Warrant, will be duly and validly issued, 
fully paid and nonassessable and free from all taxes, liens, and charges with 
respect to the issuance thereof.

          7.   ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES.  
The number of and kind of securities purchasable upon exercise of this 
Warrant and the Exercise Price shall be subject to adjustment from time to 
time as follows:

              (a)     SUBDIVISIONS, COMBINATIONS AND OTHER ISSUANCES.  If the 
Company shall at any time prior to the expiration of this Warrant subdivide 
its Equity Securities by split-up or otherwise, or combine its capital stock, 
or issue additional securities as a dividend with respect to any shares of 
its Equity Securities, the number of Warrant Shares issuable on the exercise 
of this Warrant shall forthwith be proportionately increased in the case of a 
subdivision or stock dividend, or proportionately decreased in the case of a 
combination. Appropriate adjustments shall also be made to the Exercise Price 
payable per share, but the aggregate purchase price payable for the total 
number of Warrant Shares purchasable under this Warrant (as adjusted) shall 
remain the same.  Any adjustment under this Section 7(a) shall become 
effective at the close of business on the date the subdivision or combination 
becomes effective, or as of the record date of such dividend, or in the event 
that no record date is fixed, upon the making of such dividend.

              (b)     RECLASSIFICATION, REORGANIZATION, AND CONSOLIDATION.  
In case of any reclassification, capital reorganization, or change in the 
capital stock of the Company (other than as a result of a subdivision, 
combination, or stock dividend provided for in Section 7(a) above), then, as 
a condition of such reclassification, reorganization, or change, lawful 
provision shall be made, and duly executed documents evidencing the same from 
the Company or its successor shall be delivered to the Holder, so that the 
Holder shall have the right at any time prior to the expiration of this 
Warrant to purchase, at a total price equal to that payable upon the exercise 
of this Warrant, the kind and amount of shares of stock and other securities 
and property receivable in connection with such reclassification, 
reorganization, or change by a holder of the same number of shares of capital 
stock as were purchasable by the Holder immediately prior to such 
reclassification, reorganization, or change.  In any such case appropriate 
provisions shall be made with respect to the rights and interest of the 
Holder so that the provisions hereof shall thereafter be applicable with 
respect to any shares of stock or other securities and property deliverable 
upon exercise hereof, and appropriate adjustments shall be made to the 
Exercise Price per share payable hereunder, provided the aggregate purchase 
price shall remain the same.

              (c)     NOTICE OF ADJUSTMENT.  When any adjustment is required 
to be made in the number or kind of shares purchasable upon exercise of the 
Warrant, or in the Exercise Price, the Company shall promptly notify the 
Holder of such event and of the number of shares, the adjusted Exercise Price 
and the type of securities or property thereafter purchasable upon exercise 
of the Warrant.
          
         8.   NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or scrip 
representing fractional shares shall be issued upon the exercise of this 
Warrant, but in lieu of such fractional shares the Company shall make a cash 
payment therefor on the basis of the exercise price of the warrant then in 
effect.

                                        3

         9.   NO STOCKHOLDER RIGHTS.  Prior to exercise of this Warrant, the 
Holder shall not be entitled to any rights of a stockholder with respect to 
the Warrant Shares, including (without limitation) the right to vote such 
Warrant Shares, receive dividends or other distributions thereon, exercise 
preemptive rights or be notified of stockholder meetings, and such Holder 
shall not be entitled to any notice or other communication concerning the 
business or affairs of the Company.
          
        10.  SUCCESSORS AND ASSIGNS.  The terms and provisions of this 
Warrant shall inure to the benefit of, and be binding upon, the Company and 
the Holders hereof and their respective successors and assigns.

          A Holder may transfer in whole or in part the purchase rights 
evidenced hereby to any third party to whom such rights may be transferred 
without registration or qualification under federal or state securities laws, 
provided: (a) the transferee or assignee receives a Warrant to purchase 
twenty percent (20%) of the  Warrant Shares; (b) the Company is, within a 
reasonable time after such transfer or assignment, furnished with written 
notice of the name and address of such transferee or assignee; (c) such 
transferee or assignee agrees in writing to be bound by and subject to the 
terms and conditions of this Warrant; and (d) the transferor shall have 
delivered to the Company, if reasonably requested by counsel to the Company 
an opinion of counsel substantially to the effect that the transfer or 
assignment can be effected without registration or qualification under 
applicable federal or state securities laws.
          
        11.  AMENDMENTS AND WAIVERS.  Any term of this Warrant may be amended 
and the observance of any term of this Warrant may be waived (either 
generally or in a particular instance and either retroactively or 
prospectively), with the written consent of the Company and the holders of a 
majority of the Warrants issued pursuant to the Purchase Agreement that are 
then outstanding.  Any waiver or amendment effected in accordance with this 
section shall be binding upon each holder of any Warrant Shares purchased 
under this Warrant at the time outstanding, each future holder of all such 
Warrant Shares, and the Company.
          
        12.  EFFECT OF AMENDMENT OR WAIVER.  The Holder acknowledges that by 
the operation of paragraph 11 hereof, the holders of a majority of the 
Warrants issued pursuant to the Purchase Agreement that are then outstanding 
will have the right and power to diminish or eliminate all rights of such 
Holder under this Warrant or under the Purchase Agreement.
          
        13.  GOVERNING LAW.  This Warrant shall be governed by the laws of 
the State of Delaware as applied to agreements among California residents 
made and to be performed entirely within the State of Delaware.

             INTERNATIONAL WIRELESS COMMUNICATIONS HOLDINGS, INC.
                    WARRANT  TO  PURCHASE COMMON STOCK

          This Warrant is issued to Vanguard Cellular Operating Corp. (the

hereinafter set forth and set forth in the Purchase Agreement, the Holder is 
entitled, upon surrender of this Warrant at the principal office of the 
Company (or at such other place as the Company shall notify the Holder hereof

shall be effected by:

              (a)     the surrender of the Warrant, together with a duly

          4.   NET ISSUE EXERCISE.  

              (a)     In lieu of exercising this Warrant, Holder may elect to 
receive shares equal to the value of this Warrant (or the portion thereof 
being canceled) by surrender of this Warrant at the principal office of the 
Company together with notice of such election in which event the Company 
shall issue to Holder a number of shares of Equity Securities computed using 
the following formula:

                                  X = (Y)(A-B)
                                  ------------
                                       A

     Where     X -  The number of shares of Equity Securities to be issued 
                    to Holder.
               Y -  The number of shares of Warrant Shares to be surrendered.
               A -  The fair market value of one share of the Equity 
                    Securities to be issued upon exercise of this Warrant.
               B -  Exercise Price (as adjusted to the date of such 
                    calculations).

              (b)   For purposes of this Section, the Board of Directors of 
the Company shall determine the fair market value in its good faith.  

          5.   CERTIFICATES FOR WARRANT SHARES.  Upon the exercise of the 
purchase rights evidenced by this Warrant, one or more certificates for the 
number of Warrant Shares so purchased shall be issued as soon as practicable 
thereafter, and in any event within thirty (30) days of the delivery of the 
subscription notice.

          6.   RESERVATION OF WARRANT SHARES.  The Company covenants that it 
will at all times keep available such number of authorized shares of its 
Equity Securities issuable upon exercise of this Warrant free from all 
preemptive rights with respect thereto, which will be sufficient to permit 
the exercise of this Warrant for the full number of Warrant Shares specified 
herein.  The Company further covenants that such Warrant Shares, when issued 
pursuant to the exercise of this Warrant, will be duly and validly issued, 
fully paid and nonassessable and free from all taxes, liens, and charges with

          7.   ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES.  
The number of and kind of securities purchasable upon exercise of this 
Warrant and the Exercise Price shall be subject to adjustment from time to 
time as follows:

              (a)    SUBDIVISIONS, COMBINATIONS AND OTHER ISSUANCES.  If the 
Company shall at any time prior to the expiration of this Warrant subdivide 
its Equity Securities by split-up or otherwise, or combine its capital stock, 
or issue additional securities as a dividend with respect to any shares of 
its Equity Securities, the number of Warrant Shares issuable on the exercise 
of this Warrant shall forthwith be proportionately increased in the case of a 
subdivision or stock dividend, or proportionately decreased in the case of a 
combination. Appropriate adjustments shall also be made to the Exercise Price 
payable per share, but the aggregate purchase price payable for the total 
number of Warrant Shares purchasable under this Warrant (as adjusted) shall 
remain the same.  Any adjustment under this Section 7(a) shall become 
effective at the close of business on the date the subdivision or combination 
becomes effective, or as of the record date of such dividend, or in the event 
that no record date is fixed, upon the making of such dividend. 


              (b)    RECLASSIFICATION, REORGANIZATION, AND CONSOLIDATION.  In 
case of any reclassification, capital reorganization, or change in the 
capital stock of the Company (other than as a result of a subdivision, 
combination, or stock dividend provided for in Section 7(a) above), then, as 
a condition of such reclassification, reorganization, or change, lawful 
provision shall be made, and duly executed documents evidencing the same from 
the Company or its successor shall be delivered to the Holder, so that the 
Holder shall have the right at any time prior to the expiration of this 
Warrant to purchase, at a total price equal to that payable upon the exercise 
of this Warrant, the kind and amount of shares of stock and other securities 
and property receivable in connection with such reclassification, 
reorganization, or change by a holder of the same number of shares of capital 
stock as were purchasable by the Holder immediately prior to such 
reclassification, reorganization, or change.  In any such case appropriate 
provisions shall be made with respect to the rights and interest of the 
Holder so that the provisions hereof shall thereafter be applicable with 
respect to any shares of stock or other securities and property deliverable 
upon exercise hereof, and appropriate adjustments shall be made to the 
Exercise Price per share payable hereunder, provided the aggregate purchase 
price shall remain the same.

              (c)     NOTICE OF ADJUSTMENT.  When any adjustment is required 
to be made in the number or kind of shares purchasable upon exercise of the 
Warrant, or in the Exercise Price, the Company shall promptly notify the 
Holder of such event and of the number of shares, the adjusted Exercise Price 
and the type of securities or property thereafter purchasable upon exercise 
of the Warrant.

         8.   NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or scrip 
representing fractional shares shall be issued upon the exercise of this 
Warrant, but in lieu of such fractional shares the Company shall make a cash 
payment therefor on the basis of the exercise price of the warrant then in 
effect.

                                        3

         9.   NO STOCKHOLDER RIGHTS.  Prior to exercise of this Warrant, the 
Holder shall not be entitled to any rights of a stockholder with respect to 
the Warrant Shares, including (without limitation) the right to vote such 
Warrant Shares, receive dividends or other distributions thereon, exercise 
preemptive rights or be notified of stockholder meetings, and such Holder 
shall not be entitled to any notice or other communication concerning the 
business or affairs of the Company.

        10.  SUCCESSORS AND ASSIGNS.  The terms and provisions of this 
Warrant shall inure to the benefit of, and be binding upon, the Company and 
the Holders hereof and their respective successors and assigns.
          
          A Holder may transfer in whole or in part the purchase rights 
evidenced hereby to any third party to whom such rights may be transferred 
without registration or qualification under federal or state securities laws, 
provided: (a) the transferee or assignee receives a Warrant to purchase 
twenty percent (20%) of the  Warrant Shares; (b) the Company is, within a 
reasonable time after such transfer or assignment, furnished with written 
notice of the name and address of such transferee or assignee; (c) such 
transferee or assignee agrees in writing to be bound by and subject to the 
terms and conditions of this Warrant; and (d) the transferor shall have 
delivered to the Company, if reasonably requested by counsel to the Company 
an opinion of counsel substantially to the effect that the transfer or 
assignment can be effected without registration or qualification under 
applicable federal or state securities laws.

        11.  AMENDMENTS AND WAIVERS.  Any term of this Warrant may be amended 
and the observance of any term of this Warrant may be waived (either 
generally or in a particular instance and either retroactively or 
prospectively), with the written consent of the Company and the holders of a 
majority of the Warrants issued pursuant to the Purchase Agreement that are 
then outstanding.  Any waiver or amendment effected in accordance with this 
section shall be binding upon each holder of any Warrant Shares purchased 
under this Warrant at the time outstanding, each future holder of all such 
Warrant Shares, and the Company.

        12.  Effect of Amendment or Waiver.  The Holder acknowledges that by 
the operation of paragraph 11 hereof, the holders of a majority of the 
Warrants issued pursuant to the Purchase Agreement that are then outstanding 
will have the right and power to diminish or eliminate all rights of such 
Holder under this Warrant or under the Purchase Agreement.

        13.  Governing Law.  This Warrant shall be governed by the laws of 
the State of Delaware as applied to agreements among California residents 
made and to be performed entirely within the State of Delaware.

                                   WITNESSETH:

     WHEREAS, the Company recognizes the value to it of the services of the 
Option Holder as an officer and employee and is desirous of furnishing him 
with added incentive and inducement to contribute to the success of the 
Company; and

     WHEREAS, the Board of Directors of the Company has adopted the Company's 
1996 Stock Option/Stock Issuance Plan, a copy of which is attached hereto as 
Exhibit A (hereinafter called the "Plan"); and

     WHEREAS, on February 3, 1997, pursuant to the provisions of the Plan, 
the Company's Board of Directors granted to the Option Holder, pursuant to 
the Plan, an option in respect of the number of shares and fixed and 
determined the option price and the other terms and conditions hereinafter 
set forth; 

     NOW, THEREFORE, in consideration of the mutual promises and 
representations herein contained and other good and valuable consideration, 
it is agreed by and between the parties hereto as follows:

incorporated herein by reference, the Company hereby grants to the Option 
Holder an Incentive Stock Option to purchase, on the terms and subject to the 
conditions hereinafter set forth, all or any part of an aggregate of 53,330 
shares of the Common Stock ($0.01 par value) of the Company at the exercise 
price of $9.375 per share (the "Option"), exercisable in the amounts and at 
the times set forth in this paragraph l.  Unless sooner terminated as 
provided in this Agreement, the Option shall terminate, and all rights of the 
Option Holder hereunder shall expire, on February 2, 2007.

     The Option may be exercised in installments as follows:

          (a)  up to 10,666 shares (of the total shares subject to the 
     Option) on and at any time after August 3, 1997 and prior to termination 
     of the Option;

                                        1

<PAGE>


           (b) up to 21,332 shares, less any shares previously purchased 
     pursuant to the Option, on and at any time after February 3, 1998 
     and prior to termination of the Option;

          (c)  up to 31,998 shares, less any shares previously purchased 
     pursuant to the Option, on and at any time after February 3, 1999 
     and prior to termination of the Option;

          (d)  up to 42,664 shares, less any shares previously purchased 
     pursuant to the Option, on and at any time after February 3, 2000 
     and prior to termination of the Option;

          (e)  up to 53,330 shares, less any shares previously purchased 
     pursuant to the Option, on and at any time after February 3, 2001;

provided, however, that the Option shall become immediately exercisable as to 
all of the shares upon the occurrence of any one of the following events:

          (a)  Upon the termination of the Option Holder's employment by the 
     Company other than for "cause" as hereinafter defined, or

          (b)  Upon the Option Holder's terminating his employment with the 
     Company following a "change of control," as hereinafter defined, upon the 
     occurrence of the following events (a "Triggering Event"): (i) his 
     authority and/or responsibility are substantially reduced, without his 
     consent below that in effect as of the date hereof, (ii) the Option 
     Holder is required to change his residence or principal place of business 
     from Greensboro, North Carolina, or (iii) the travel obligations of the 
     Option Holder are, without his consent, increased materially above those 
     in effect as of the date hereof, or (iv) he is not reelected to the 
     Company' Board of Directors, or

          (c)  Upon the death of the Option Holder while employed by the 
     Company, or

          (d)  Upon the Option Holder's becoming disabled within the meaning 
     of Section 22(e)(3) of the Internal Revenue Code of 1986 while employed by 
     the Company (other than by reason of chronic alcoholism or addiction to 
     narcotics or an intentionally self-inflicted injury).

     For purposes of this paragraph 1, "cause" shall mean termination due to 
(i) continued intentional refusal to perform the duties for which employed 30 
days following receipt by the Option Holder of one or more written warnings 
from the Board of Directors of the Company specifying in detail the Option 
Holder's misconduct, (ii) fraud or embezzlement committed against the 
Company, or (iii) the Option Holder's conviction for a felony.
     
     For purposes of this paragraph 1, a "change of control" shall be deemed 
to have occurred upon the occurrence of any of the following events:

          (i)  Any "person" (as such term is used in Sections 13(d) and 
     14(d)(2) of the Securities Exchange Act of 1934, as amended (the "Exchange 
     Act") but excluding any 

                                        2

<PAGE>


    employee benefit plan of the Company) is or becomes the "beneficial 
    owner" (as defined in Rule 13d-3 under the Exchange Act), directly or 
    indirectly, of securities of the Company representing 50% or more of the 
    combined voting power of the Company's outstanding securities then 
    entitled ordinarily (and apart from rights accruing under special 
    circumstances) to vote for the election of directors; or

          (ii) Individuals who are "Continuing Directors" (as hereinafter 
     defined) cease for any reason to constitute at least a majority of 
     the Board of Directors; or
     
         (iii) The Board of Directors shall approve a sale of all or 
     substantially all of the assets of the Company; or

          (iv) The Board of Directors shall approve any merger, 
     consolidation, or like business combination or reorganization of 
     the Company the consummation of which would result in the occurrence 
     of any event described in clause (i) or (ii) above.

     For purposes of the foregoing, "Continuing Directors" shall mean (i) the 
directors of the Company in office on the date hereof and (ii) any successor 
to any such director (and any additional director) who after the date hereof 
(y) was nominated or selected by a majority of the Continuing Directors in 
office at the time of his nomination or selection and (z) who is not an 
"affiliate" or "associate" (as defined in Regulation 12B under the Exchange 
Act) of any person who is the beneficial owner, directly or indirectly, of 
securities representing 50% or more of the combined voting power of the 
Company's outstanding securities then entitled ordinarily to vote for the 
election of directors.

     2.   The Option or any part thereof may, to the extent that it is 
exercisable, be exercised in the manner and payment of the aggregate exercise 
price for the number of shares purchased shall be made in the manner provided 
in Section I.A of Article Two of the Plan, including by payment consisting in 
full or in part of shares of Common Stock.

     3.   The Option or any part thereof may be exercised during the lifetime 
of the Option Holder only by the Option Holder and, except as provided in 
paragraph 4 hereinbelow, may be exercised only while the Option Holder is an 
employee of the Company, its parent or any of its subsidiaries.

     4.   If the Option Holder ceases to be an employee of the Company, its 
parent, or any of its subsidiaries for any reason (other than his death or 
permanent and total disability), the Option, to the extent it is exercisable 
immediately prior to such termination, may be exercised at any time within 
three months after the date of termination of his employment but in no event 
after the Option has expired.  If the Option Holder ceases to be an employee 
by reason of his death or permanent and total disability, the Option may be 
exercised, at any time within one year after such termination but in no event 
after the Option has expired, by the Optionee or the person or persons to 
whom the Option Holder's rights under the Option shall pass by will or by the 
laws of descent and distribution.

                                        3

     5.   Except as provided above with respect to transfers upon the death 
of the Option Holder, the Option shall not be transferred, assigned, pledged 
or hypothecated in any way, whether by operation of law or otherwise. Upon 
any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of 
the Option or any right or privilege confirmed hereby contrary to the 
provisions hereof, the Option and the rights and privileges confirmed hereby 
shall immediately become null and void.

     6.   If the shares of Common Stock of the Company are increased, 
decreased, changed into, or exchanged for a different number or kind of 
shares or securities through merger, consolidation, combination, exchange of 
shares, other reorganization, recapitalization, reclassification, stock 
dividend, stock split or reverse stock split in which the Company is the 
surviving entity, an appropriate and proportionate adjustment shall be made, 
as provided in Section VI.C of Article One of the Plan, in the number or kind 
of shares allocated to any unexercised part of the Option.  In the event the 
Company's Board of Directors approves a consolidation or a merger in which 
the Company is not the surviving corporation, or any other merger, or share 
exchange in which the stockholders of the Company exchange their stock for 
stock of another corporation, or in the event of complete liquidation of the 
Company, or in the case of a tender offer for 50% or more of the combined 
voting power of the Company's outstanding securities, the Option shall 
thereupon become immediately exercisable (to the extent it is not already so 
exercisable).  In the event the consideration to be received for Common Stock 
in any such transaction is cash, the Option Holder shall be entitled to 
receive from the Company at the time the transaction is consummated cash in 
an amount equal to the difference between the exercise price of aggregate 
number of shares then subject to the Option and not yet purchased by the 
Option Holder and the price to be paid for such number of shares of Common 
Stock of the Company in the consolidation, merger, liquidation, or tender 
offer.  In the event such transaction is for consideration other than cash, 
the Option Holder shall be entitled to receive a replacement option on the 
same terms and conditions as the Option except that there shall be 
substituted for the Common Stock the consideration that would have been 
received by the Option Holder as a result of such transaction had the Option 
been exercised immediately prior to consummation of such transaction.

     7.   The Option Holder recognizes that any registration of the Option 
and the shares of Common Stock issuable upon its exercise under the 
Securities Act of 1933 or under the securities laws of any state shall be at 
the option of the Company.  The Option Holder acknowledges that, absent 
registration, under present federal securities regulations, he will be 
required to hold any shares purchased pursuant to exercise of the Option for 
a period of not less than one year following full payment for said shares and 
that thereafter the shares may be sold only in compliance with Rule l44 of 
the Securities and Exchange Commission.  The Option Holder further 
acknowledges that, notwithstanding registration, if, at the time of exercise 
of the Option, he is deemed an "affiliate" of the Company as defined in said 
Rule l44, any shares purchased thereunder will nevertheless be subject to 
sale only in compliance with Rule l44 (but without any holding period), and 
that the Company may take such action as is necessary to assure such 
compliance, including placing restrictive legends on certificates evidencing 
such shares and delivering stop transfer instructions to the Company's 
transfer agent.

     8.   Any notice to be given to the Company shall be addressed to the 
Secretary of the Company at the principal office of the Company. 

     9.   Nothing herein contained shall affect the right of the Company, 
subject to the terms of any existing contractual arrangement to the contrary, 
to terminate the Option Holder's employment at any time for any reason 
whatsoever.

     10.  This Agreement shall be binding upon and inure to the benefit of 
the Option Holder, his personal representatives, heirs and legatees, but 
neither this Agreement nor any rights hereunder shall be assignable or 
otherwise transferable by the Option Holder except as expressly set forth in 
this Agreement or in the Plan.

                                WITNESSETH:

          WHEREAS, the Company recognizes the value to it of the services of 
the Option Holder and is desirous of furnishing him with added incentive and 
inducement to contribute to the success of the Company; and

Holder an option in respect of the number of shares and fixed and determined

          2.   The Option may be exercised in installments as follows:

              (a)   up to one-fifth (1/5) of the shares (of the total shares

              (e)   up to all of the shares, less any shares previously

provided, however, that  the Option shall become fully vested and immediately 
exercisable as to all of the Option shares upon the occurrence of any one of 
the following events:

              (a)  [Upon the termination by the Company of the Option 
Holder as a director of the Company for any reason] [Upon the Company's 
terminating the Option Holder as a consultant to the Company] [Upon

              (b)  Upon the occurrence of a "change of control" of the

          For purposes of this Section 2, a "change of control" shall be 
deemed to have occurred upon the occurrence of any of the following events:
          
                    (i)  Any "person" (as such term is used in Sections

Company) is or becomes the "beneficial owner" (as defined in Rule 13d-3 
under the Exchange Act), directly or indirectly, of securities of the

                   (ii) Individuals who are "Continuing Directors" (as 
hereinafter defined) cease for any reason to constitute at least a majority

<PAGE>

                  (iii) The Board of Directors of the Company shall approve a 
sale of all or substantially all of the assets of the Company; or
                    
                   (iv) The Board of Directors of the Company shall approve 
any merger, consolidation, or like business combination or reorganization of 
the Company the consummation of which would result in the occurrence of any 
event described in clause (i) or (ii) above.

          For purposes of the foregoing, "Continuing Directors" shall mean 
(i) the directors of the Company in office on the date hereof and (ii) any 
successor to any such director (and any additional director) who after the 
date hereof (y) was nominated or selected by a majority of the Continuing 
Directors in office at the time of his nomination or selection and (z) who is 
not an "affiliate" or "associate" (as defined in Regulation 12B under the 
Exchange Act) of any person who is the beneficial owner, directly or 
indirectly, of securities representing 50% or more of the combined voting 
power of the Company's outstanding securities then entitled ordinarily to 
vote for the election of directors.

          3.   While this Option remains outstanding and exercisable in 
accordance with the terms hereof, the Option Holder may exercise, in whole or 
in part, the Option by:

              (a)   surrendering the Option, together with a duly executed 
copy of the form of exercise notice attached hereto, to the Secretary of the 
Company at its principal offices; and

              (b)   making payment to the Company of an amount of cash equal 
to the aggregate Exercise Price for the number of Option Shares being 
purchased.

          4.   If the Option Holder ceases to be [a director of the 
Company] [a consultant to the Company] [an employee of Vanguard] for any 
reason (other than his death or permanent and total disability), the 
Option, to the extent it is exercisable immediately prior to such 
termination, may be exercised at any time within three months after the 
date of termination of his employment but in no event after the Option 
has expired.  If the Option Holder ceases to be [a director of the 
Company] [a consultant to the Company] [an employee of Vanguard] by 
reason of his death or permanent and total disability, the Option may be 
exercised, at any time within one year after such termination but in no 
event after the Option has expired, by the Optionee or the person or 
persons to whom the Option Holders' rights under the Option shall pass 
by will or by the laws of descent and distribution.
          
          5.   Except as provided in paragraph 4 above, the Option shall not 
be transferred, assigned, pledged or hypothecated in any way, whether by

hypothecate or otherwise dispose of the Option or any right or privilege 
confirmed hereby contrary to the provisions hereof, the Option and the rights 
and privileges confirmed hereby shall immediately become null and void.

<PAGE>

          6.   (a)  In lieu of exercising this Option, Option Holder may 
elect to receive shares equal to the value of this Option (or the portion 
thereof being canceled) by surrender of this Option at the principal office 
of the Company together with notice of such election in which event the 
Company shall issue to Option Holder a number of shares of Equity Securities 
computed using the following formula:

                                 X = (Y)(A-B)
                                 ------------
                                      A
     
       Where    X -   The number of shares of Common Stock to be issued 
                      to Option Holder.
                Y -   The number of Option shares to be surrendered.
                A -   The fair market value of one share of the Common Stock 
                      to be issued upon exercise of this Option.  
                B -   Exercise Price (as adjusted to the date of 
                      such calculations).

               (b)  For purposes of this Section, the Board of Directors 
of the Company shall determine the fair market value in its good faith.  
Notwithstanding the foregoing, Option Holder may surrender only that portion 
of the Option which is exercisable pursuant to Section 1 hereof.  

          7.   Upon the exercise of the purchase rights evidenced by this 
Option, one or more certificates for the number of Option shares so purchased 
shall be issued as soon as practicable thereafter, and in any event within 
thirty (30) days of the delivery of the subscription notice.
          
          8.   The Company covenants that it will at all times keep available 
such number of authorized shares of its Common Stock that may be issuable 
upon exercise of this Option free from all preemptive rights with respect 
thereto, which will be sufficient to permit the exercise of this Option for 
the full number of Option shares specified herein.  The Company further 
covenants that such Option shares, when issued pursuant to the exercise of 
this Option, will be duly and validly issued, fully paid and nonassessable.  
          
          9.   The number of and kind of securities purchasable upon exercise 
of this Option and the Exercise Price shall be subject to adjustment from 
time to time as follows:

              (a)   If the Company shall at any time prior to the expiration 
of this Option subdivide its Common Stock by split-up or otherwise, or 
combine its capital stock, or issue additional securities as a dividend with 
respect to any shares of its Common Stock, the number of Option shares 
issuable upon the exercise of this Option shall forthwith be proportionately 
increased in the case of a subdivision or stock dividend, or proportionately 
decreased in the case of a combination.  Appropriate adjustments shall also 
be made to the Exercise Price payable per share, but the aggregate Exercise 
Price payable for the total number of Option shares purchasable under this 
Option (as adjusted) shall remain the same.  Any 

                                        4

<PAGE>


adjustment under this Section 9(a) shall become effective at the close of 
business on the date the subdivision or combination becomes effective, or as 
of the record date of such dividend, or in the event that no record date is 
fixed, upon the making of such dividend.

              (b)   In the event of any reclassification, capital 
reorganization, or change in the capital stock of the Company (other than as 
a result of a subdivision, combination, or stock dividend provided for in 
Section 9(a) above), then, as a condition of such reclassification, 
reorganization, or change, lawful provision shall be made, and duly executed 
documents evidencing the same from the Company or its successor shall be 
delivered to the Option Holder, so that the Option Holder shall have the 
right at any time prior to the expiration of this Option to purchase, at a 
total price equal to that payable upon the exercise of this Option, the kind 
and amount of shares of stock and other securities and property receivable in 
connection with such reclassification, reorganization, or change by a holder 
of the same number of shares of capital stock as were purchasable by the 
Option Holder immediately prior to such reclassification, reorganization, or 
change.  In any such case appropriate provisions shall be made with respect 
to the rights and interest of the Option Holder so that the provisions hereof 
shall thereafter be applicable with respect to any shares of stock or other 
securities and property deliverable upon exercise hereof, and appropriate 
adjustments shall be made to the Exercise Price per share payable hereunder, 
provided the aggregate Exercise Price shall remain the same.  

              (c)   When any adjustment is required to be made in the number 
or kind of shares purchasable upon exercise of the Option, or in the Exercise 
Price, the Company shall promptly notify the Option Holder of such event and 
of the number of shares, the adjusted Exercise Price and the type of 
securities or property thereafter purchasable upon exercise of the Option.

          10.  No fractional shares shall be issued upon the exercise of this 
Option, but in lieu of such fractional shares the Company shall make a cash 
payment equal to the fair market value of such fractional shares on the 
exercise date of the Option with respect to the fractional shares.  
          
          11.  The Option Holder recognizes that any registration of the 
Option and the shares of Common Stock issuable upon its exercise under the 
Securities Act of 1933 or under the securities laws of any state shall be at 
the option of the Company.  The Option Holder acknowledges that, absent 
registration, under present federal securities regulations, he will be 
required to hold any shares purchased pursuant to exercise of the Option for 
a period of not less than one year following full payment for said shares and 
that thereafter the shares may be sold only in compliance with Rule 144 of 
the Securities and Exchange Commission.  The Option Holder further 
acknowledges that, notwithstanding registration, if, and at the time of 
exercise of the Option, he is deemed an "affiliate" of the Company as defined 
in said Rule 144, any shares purchased thereunder will nevertheless be 
subject to sale only in compliance with Rule 144 (but without any holding 
period), and that the Company may take such action as is necessary to assure 
such compliance, including placing restrictive legends on certificates 
evidencing such shares and delivering stop transfer instructions to the 
Company's transfer agent.

International Wireless Communications, Inc.
400 South El Camino Real Road, Suite 1275
San Mateo, California 94402


Gentlemen:

     I am simultaneously with the execution of this letter, acquiring from 
International Wireless Communications Holdings, Inc. ("IWCH") a nonstatutory 
option to purchase _____ shares of Common Stock of IWCH (the "Common Stock") 
at a purchase price of $9.375 per share.  As an inducement to IWCH to issue 
such option to me, I hereby represent to and agree with IWCH as follows:

     1.   The Option is being acquired, and the Common Stock issuable upon 
exercise of the Option will be acquired, for investment for my own account, 
and not as nominee or agent, and not with the view to the resale or 
distribution in any part thereof, and I have no present intention of selling, 
granting any participation in, or otherwise distributing the same.

     2.   I do not have any contract, undertaking, agreement or arrangement 
with any person to sell, transfer or grant participations to such person or 
to any third person, with respect to any of the Securities. 

     3.   I have received all information I consider necessary or appropriate 
for deciding whether to receive an Option and have had an opportunity to ask 
questions and receive answers from IWCH regarding the terms and conditions of 
the offering of the Options and the business properties, prospects and 
financial condition of IWCH.  I am an investor in securities of companies in 
the development stage and acknowledges that I am able to fend for myself, can 
bear the economic risk of my investment, and have such knowledge and 
experience in financial or business matters that I am capable of evaluating 
the merits and risks of the investment in the Options.  

     4.   I understand that the securities I am purchasing are characterized 
as "restricted securities" under the federal securities laws inasmuch as they 
are being acquired from IWCH in a transaction not involving a public offering 
and that under such laws and applicable regulations such securities may be 
resold without registration under the Act only in certain limited 
circumstances.

                                        1

<PAGE>


     5.   I understand that a restriction will be placed on my Option and on 
the Common Stock issuable upon exercise thereof as follows:

     This Option [the Common Stock represented by this Certificate] has 
     not been registered under the Securities Act of 1933, as amended, 
     may not be sold, offered for sale, pledged, hypothecated, or 
     otherwise transferred except pursuant to an effective registration 
     statement under the Securities Act of 1933 or an opinion of counsel 
     satisfactory to the Company that registration is not required under 
     such Act or unless sold pursuant to Rule 144 under such Act.

                         Sincerely,



                         -------------------------------------------

International Wireless Communications Holdings, Inc.



Ladies and Gentlemen:

     We have acted as counsel to Vanguard Cellular Financial Corp., a North 
Carolina corporation (the "Company"), in connection with that Agreement of 
even date herewith between the Company and International Wireless 
Communications Holdings, Inc. (the "Agreement").  Unless otherwise defined 
herein, capitalized terms used herein and defined in the Agreement are used 
herein as therein defined.  This opinion is furnished to you pursuant to 
Section 4 of the Agreement.

                               DOCUMENTS EXAMINED
                               ------------------

     In connection with the preparation of this opinion, we have reviewed the 
following:

          (a)  The Agreement;

          (b)  Certified copies of the incorporation documents and bylaws of 
the Company as in effect on the date hereof;

          (c)  Certified copies of resolutions adopted by the Board of 
Directors of the Company relating to the Agreement;

          (d)  Certificate of Existence of the Company as certified by the 
Secretary of State of North Carolina on March 11, 1997 (the "Certificate 
of Existence"); and

          (e)  Such other documents as we consider necessary or appropriate 
for purposes of rendering the opinions set forth below.

     In all such examinations, we have assumed the authenticity and 
completeness of all documents submitted to us as originals and the conformity 
to originals and the completeness of all documents submitted to us as 
photostatic, notarial or certified copies.  We have also assumed the legal 
capacity of all persons executing documents examined by us and the due 
authorization, execution and delivery of all documents to be delivered by 
parties other than the Company.

Whenever our opinion herein as "to the best of our knowledge," such opinion 
is limited to and based upon the actual knowledge of attorneys in this firm 
who have devoted substantive attention to the transactions contemplated by 
the Agreement or who regularly represent the Company.

     Except for our review of the documents and records listed above, we have 
made no independent factual investigation in connection with the preparation 
of this opinion.  To the extent that matters of fact may be deemed material 
to this opinion, we have relied (without independent verification) on the 
representations and warranties of the Company in the Agreement.

     We have investigated such questions of North Carolina law as we have 
deemed necessary for the purpose of rendering this opinion.  In that regard, 
we call your attention to the fact that the Agreement states that it is to be 
construed in accordance with and governed by the laws of the State of 
Delaware. Please be advised that we are members of the bar of the State of 
North Carolina and do not purport to be experts in the laws of any 
jurisdiction other than the State of North Carolina.  Accordingly, this 
opinion is limited in all respects to the laws of the State of North Carolina 
and is furnished as if the Agreement was governed by North Carolina law, 
notwithstanding the choice of law provisions therein.

                                    OPINIONS
                                    --------

     Based solely on the foregoing, and subject to the assumptions, 
limitations and qualifications set forth herein, we are of the opinion that:

     1.   The Company is a corporation duly organized, validly existing and 
in good standing under the laws of the State of North Carolina.

     2.   The Company has the corporate power and authority to enter into and 
perform all of its obligations under the Agreement.

     3.   The execution, delivery and performance by the Company of the 
Agreement is duly authorized by all requisite corporate action and do not and 
will not (a) violate any provision of (i) the certificate of incorporation or 
the bylaws of the Company, or (ii) any North Carolina law or, to the best of 
our knowledge, any order, writ, judgment, injunction, decree, determination 
or award of any court, arbitrator or government, commission, board, bureau, 
agency or other instrumentality applicable to or binding upon the Company, or 
(b) to the best of our knowledge of or constitute a default under any 
material indenture or loan or credit agreement or any other agreement, lease 
or instrument to which the Company is party or by which the Company or the 
Company's properties may be bound or affected.

     4.   The Agreement constitutes a legal, valid and binding obligation of 
the Company, enforceable against it in accordance with its terms.

                         LIMITATIONS AND QUALIFICATIONS

     The opinions expressed above are subject to the following qualifications 
and limitations:

          (a)  Enforceability of the Agreement may be limited by bankruptcy, 
     reorganization, fraudulent conveyance (including, without limitation, 
     Section 548 of the Bankruptcy Code (11 U.S.C. Section 548) and similar 
     provisions of state law), insolvency or similar laws affecting the 
     enforcement of creditors' rights generally or by general principles of 
     equity (regardless whether enforceability is considered in a proceeding 
     in equity or at law).

          (b)  Insofar as our opinion relates to the existence of the 
     Company, we have relied upon the Certificate of Existence, no further 
     investigation having been performed by us.
