                    OMNIPOINT CORPORATION AND SUBSIDIARIES
             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                        
1. GENERAL:

          The accompanying condensed consolidated financial statements of
Omnipoint Corporation and subsidiaries (the "Company" or "Omnipoint") have been
prepared by the Company without audit pursuant to the rules and regulations of
the Securities and Exchange Commission (the "SEC"). Certain information and
footnote disclosures normally included in financial statements presented in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to the rules and regulations of the SEC. The Company believes
the disclosures made are adequate to make the information presented not
misleading. However, the condensed consolidated financial statements should be
read in conjunction with the consolidated financial statements and notes thereto
included in the Company's annual report on Form 10-K for the year ended December
31, 1997.

          In the opinion of the Company, the accompanying unaudited condensed
consolidated financial statements reflect all adjustments necessary to present
fairly the financial position of the Company as of September 30, 1998 and
December 31, 1997, and the results of operations for the three and nine months
ended September 30, 1998 and September 30, 1997 and cash flows for the nine
months ended September 30, 1998 and September 30, 1997. Interim results are not
necessarily indicative of fiscal year performance because of the impact of
seasonal or short-term variations.

          Certain prior period amounts have been reclassified to conform to
current presentation.

2. LOSS PER COMMON SHARE:

          The Company computes basic and diluted earnings per share in
accordance with the Statement of Financial Accounting Standards No. 128,
"Earnings per Share", ("SFAS 128") which the Company adopted as of December 31,
1997. As the Company is in a loss position, both basic and diluted earnings per
share are the same amount. Options and warrants to purchase 9,279,989 and
7,415,490 shares of common stock outstanding as of September 30, 1998 and 1997,
respectively, have been excluded from the calculation of diluted net loss per
share as the effect of their inclusion would have been anti-dilutive. The
Company's 325,000 shares of preferred stock, convertible into 10,445,123 shares
of common stock have also been excluded from the calculation of diluted net loss
per share as the effect of their inclusion would have been anti-dilutive.

3. INVENTORY:

          Inventory consists of the following (in thousands):

4. OMNIPOINT MIDWEST FINANCING FACILITY:

          In January 1998, the Company, through an indirect, wholly-owned
subsidiary, Omnipoint Midwest Holdings LLC ("OMWH"), entered into a credit
facility agreement (the "Midwest Facility") with Northern Telecom Inc.
("NorTel") for up to $400 million to provide financing to OMWH. The Midwest
Facility will finance the buildout of networks in certain Midwest markets
including Detroit, Indianapolis, and certain other designated markets. Pursuant
to the D&E Communications, Inc./Omnipoint joint venture ("PCS One") and its need
for financing, the Midwest Facility was amended and reduced from $400 million to
$360 million in available financing. In a related transaction, a separate 
$40 million financing facility was created for the PCS One joint venture. The
Midwest Facility will finance the buildout of networks in certain Midwest
markets including Detroit, Indianapolis, and certain other designated markets.
The Midwest Facility provides that up to $85 million is available to OMWH for
any purpose, including an inter-company loan to the Company. The Company at its
sole option can repay the $85 million portion of the loan in either cash or the
Company's Common Stock under certain conditions.

ended September 30, 1998 and it replaces an earlier draft which the Company's 
filing agent filed with the Securities and Exchange Commission by mistake.

             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  -CONTINUED-
                                        
          Under the terms of the Midwest Facility, OMWH is subject to certain
financial and operational covenants, including but not limited to restrictions
on OMWH's ability to pay dividends and level of indebtedness. The Midwest
Facility is collateralized by substantially all the assets of OMWH and its
license and operating subsidiaries for the Midwest and certain other designated
markets, including a pledge of all capital stock of each such license and
operating subsidiaries, as well as all capital stock of OMWH owned by an
indirect, wholly-owned subsidiary of the Company, Omnipoint PCS Entrepreneurs
Two, LLC (" OPCS Two LLC").

          The $85 million portion of the Midwest Facility which has no required
amortization, matures in March 2008. Interest on such portion is payable semi-
annually (which interest may be accreted until March 2004). The remaining
portion of the Midwest Facility which is available to finance equipment
purchases from NorTel and certain eligible third party expenses is payable in
installments beginning in 2002, with a final payment due December 2006. Interest
on such amount is payable quarterly with regard to base rate loans and at the
end of an applicable interest period with regard to LIBOR rate loans. The
Midwest Facility was provided in conjunction with the amendment to the Northern
Telecom Supply Agreement, wherein OMWH, together with other affiliates of the
Company, agreed to purchase up to $210 million of equipment and services from
Northern Telecom over a four-year period and to purchase GSM PCS network
equipment exclusively from Northern Telecom in the Midwest markets.

          Pursuant to the amended Midwest Facility, PCS One entered into a 
credit facility agreement with NorTel for up to $40 million. The Company entered
into a contribution agreement where the Company and D&E Communications, Inc.
have a joint and several obligation to contribute funds not to exceed the lesser
of $50 million or the balance on the PCS One facility plus dividends paid to D&E
Communications, Inc. and the Company. Since the Company and D&E have already
jointly contributed $23.6 million to PCS One, which is greater than the current
draw on the facility, the maximum remaining obligation was zero as of September
30, 1998. If current ownership percentages of the joint venture are maintained,
the Company's anticipated future contribution to meet this obligation would be
less than $14 million.

5. $750 MILLION PERMANENT CREDIT FACILITY:

          In February 1998, Omnipoint Communications Inc. ("OCI"), an indirect,
wholly-owned subsidiary of the Company, refinanced a $516 million interim credit
facility (the "Interim Credit Facility") with a $750 million credit facility
with DLJ Capital Funding Inc. ("DLJ") and certain other parties (the "Permanent
Credit Facility" or the "Agreements") pursuant to (a) a $595 million credit
facility agreement and (b) a $155 million note purchase agreement. The 
$595 million credit facility agreement may be increased under certain
circumstances. In February 1998, OCI borrowed $450 million (of which $295
million was funded under the credit facility agreement and $155 million was
funded under the note purchase agreement). A portion of the proceeds,
approximately $351.6 million, was used to fully repay outstanding borrowings
including accrued interest on the Interim Credit Facility. An additional $50
million and $250 million were borrowed under the Permanent Credit Facility in
March and April 1998, respectively. Also during the nine months ended September
30, 1998, certain holders, at their option, converted $44.5 million of the notes
purchased under the note purchase agreement into a portion of the credit
facility. Under the terms of the Agreements, OCI and the Company are subject to
certain financial and operational covenants, including restrictions on the
Company's ability to pay dividends, level of indebtedness, and certain other
financial maintenance requirements. The Agreements are collateralized by
substantially all of the assets of OCI and its license subsidiary, including a
pledge of all capital stock and such license subsidiary, as well as 95.6% of the
capital stock of OCI. The obligations of OCI under the Agreements are supported
by guarantees from Omnipoint Holdings, Inc., Omnipoint Investments Two, Inc. and
Omnipoint PCS, Inc., each a direct, wholly-owned subsidiary of the Company, and
collateralized by substantially all of their respective assets. The principal
amount of the Agreements is payable quarterly in installments of one quarter of
one percent of the principal balance, which began June 1998, with a final
payment due February 2006. Interest on such amount is payable quarterly in
arrears or at the end of an applicable interest period as provided in the
Agreements.

6. PREFERRED STOCK OFFERING:

          In May 1998, the Company completed the private placement of 6,500,000
depositary shares (the "Depositary Shares"), each representing 1/20 of a share
of 7% Cumulative Convertible Preferred Stock (the "Offering" or "Preferred
Stock"). Each Depositary Share has a liquidation preference of $50, equivalent
to $1,000 per share of Preferred Stock or $325 million for the entire 325,000 
shares of Preferred Stock. Net proceeds to the Company totaled approximately
$252.2 million.

          Simultaneously with the closing of the Offering, the purchasers of the
Depositary Shares deposited approximately $62.8 million of the gross proceeds
into a restricted deposit account (the "Deposit Account"). The holder of each
Depositary Share is entitled to a quarterly payment from the Deposit Account in
an amount equal to $0.875 per Depositary Share. The quarterly payments (paid on
February, May, August, and November of each year)   commence August 1998 and
continue until May 2001 (the "Deposit Expiration Date"). The Company, at its
option, may instruct the deposit agent to disburse the quarterly payment in the
form of cash or shares of the Company's common stock. The number of shares of
common stock to be paid is calculated by dividing the quarterly payment amount
by 95% of the market value of the common stock as of the date notice is given by
the Company to the deposit agent. Additionally, the Company, at its option, may
elect to defer delivery of the quarterly payment until the next quarterly
payment date or

                                  -CONTINUED-
                                        
any subsequent quarterly payment date. However, the payment cannot be delayed
beyond the Deposit Expiration Date. As of the Deposit Expiration Date, all
remaining funds in the Deposit Account will be delivered to holders of the
Depositary Shares in the form of common stock or cash. In the event of a
quarterly payment made in the form of common stock at or prior to the Deposit
Expiration Date, the deposit agent will reimburse the Company for the value of
the quarterly payment in cash from the Deposit Account.  In August, the deposit
agent disbursed a quarterly cash payment of $5.7 million to holders of the
Depositary Shares drawn against the Deposit Account.

          Holders of the Depositary Shares are entitled to receive cumulative
annual dividends of 7% of the liquidation preference per Depositary Share. The
dividends are payable quarterly in arrears, when and if declared by the Board of
Directors, commencing August 2001. Cumulative annual dividends begin to accrue
on the Depositary Shares beginning May 2001. If the Company elects early
termination of the Deposit Account, dividends will begin to accrue immediately
preceding the date of the early termination.

          Each Depositary Share may be converted at any time at the option of
the holder into 1.6069 shares of common stock. The Depositary Shares may not be
redeemed prior to May 2001. On or after May 2001, the Depositary Shares may be
redeemed, in whole or in part, at the option of the Company, in cash or common
stock or a combination thereof, plus all accrued and unpaid dividends to the
redemption date. The redemption price is $52 in 2001, declining to $50 in 2005
and thereafter.

7. RETURN OF C-BLOCK LICENSES:

          The FCC issued a reconsideration order (the "Order") which went into
effect April 1998, allowing companies holding C-block Personal Communications
Services licenses several options to restructure their license holdings and
associated obligations. The Company elected under the amnesty option of the
Order to return 14 Basic Trading Area ("BTA") licenses. The Company also elected
to forgo the respective 10 percent deposits on these licenses in return for the
option to re-bid on the licenses. Thus with respect to the returned licenses,
the Company recognized a reduction of $110.5 million in debt and $13.4 million
in accrued interest. The net book value of the fully returned licenses was
$139.1 million.

          The Company also elected a second option, the disaggregation option,
to return half the spectrum on four BTAs covering the Philadelphia, Pa.,
Reading, Pa., Dover, De., and Atlantic City, N.J. markets. Under the
disaggregation option, the Company retains 15 MHz in each of the four BTAs while
returning 15 MHz. The disaggregation extinguishes 50 percent of the outstanding
debt on the licenses and prohibits the Company from owning or re-bidding on the
licenses for two years from the date of the re-auction. As a result of the
disaggregation, the Company recognized a reduction of $131.8 million in debt,
and $26.4 million in accrued interest. The net book value of the disaggregated
50% of the licenses was $156.9 million.

          On a nominal basis, the two elections reduced the Company's debt and
accrued interest by approximately $337 million. Additionally, the Company will
receive approximately a $2.7 million refund for FCC interest previously paid on
returned licenses. As a result of the amnesty and disaggregation elections, the
Company recognized an extraordinary loss of $11.1 million in the second quarter
of 1998.

8. OMNIPOINT MIAMI BOSTON BANK OF AMERICA FINANCING FACILITY:

          In June 1998, Omnipoint MB Holdings, LLC ("OMB"), an indirect, wholly-
owned subsidiary of the Company, entered into a $160 million credit facility
agreement with Bank of America International Limited (the "BankAmerica
Facility"). The BankAmerica Facility replaced $150 million of credit under the
July 1997 Ericsson MB Facility. Proceeds from the BankAmerica Facility are
available to finance equipment purchases for the Miami and Boston markets.
Interest on such amount is payable quarterly in arrears or at the end of each
applicable interest period as provided in the BankAmerica Facility. Principal
amortization on the facility begins no earlier than January 2000 with a final
maturity due no earlier than July 2004. During the third quarter of 1998, OMB
borrowed $104.8 million from the BankAmerica Facility.  EXPORTKREDITNAMNDEN
("EKN"), the Swedish Export Credit Guaranty Board, guarantees a portion of the
outstanding balance of the BankAmerica Facility. Contemporaneously with the
closing of the BankAmerica Facility, the Ericsson MB Facility was amended and
restated to, among other things eliminate the $150 million portion that was
replaced by the BankAmerica Facility. Ericsson was granted a five-year exclusive
right to supply network equipment for the Boston and Miami markets.

          Under the terms of the BankAmerica Facility, the Company is subject to
certain financial and operational covenants, including but not limited to
restrictions on the ability to pay dividends and level of indebtedness. The
BankAmerica Facility ranks pari passu with the Ericsson MB Facility and is
collateralized by substantially all the assets of OMB and each of the license
and operating subsidiaries for the Boston and Miami markets, including a pledge
of all capital stock of each such license and operating subsidiaries as well as
capital stock of OMB.

9. PURCHASE OF URBAN WIRELESS' CUSTOMER BASE:

          On September 30, 1998, the Company, through its subsidiary, Omnipoint
Communications Services, LLC ("OCS") purchased the outstanding customer base of
Urban Wireless Inc. in a non-cash transaction for $4.2 million. The Company
forgave approximately $3.7 million in net accounts receivable due from Urban
Wireless and issued a credit in the amount of $.5 million in exchange for the
customer base which was subsequently determined to consist of approximately
20,500 subscribers.

10. COMMITMENTS AND CONTINGENCIES:

          In September 1998, the Company, through its subsidiary OCS, entered
into a joint venture agreement with D&E Communications Inc. ("D&E") resulting in
the formation of D&E/Omnipoint Wireless Joint Venture. PCS One entered into a
financing agreement with Northern Telecom, Inc. to help finance the buildout of
its central Pennsylvania markets. As a condition of the financing agreement, the
Company and D&E have a joint and several obligation to contribute funds not to
exceed the lesser of $50 million or the balance on the financing agreement plus
dividends in the event of any default on the financing agreement by PCS One.
Since the Company and D&E have already jointly contributed $23.6 million to 
PCS One, which is greater than the amount drawn on the facility, the maximum
remaining obligation was zero as of September 30, 1998.  If current
ownership percentages of the joint venture are maintained, the Company's 
anticipated future contribution to meet this obligation would be less than 
$14 million.

          The Company, through its subsidiaries, is also in various stages of
negotiation for infrastructure equipment, handsets, accessories and services
from various suppliers. These new contracts could require minimum purchase
commitments from the Company. Management believes that the Company will fulfill
these commitments in the normal course of business.

11. RECENT ACCOUNTING PRONOUNCEMENTS:

          Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130 ("SFAS 130"), "Reporting Comprehensive Income".
SFAS 130 requires the reporting of comprehensive income (loss) in addition to
net income (loss) from operations. Comprehensive income is a more inclusive
reporting methodology that includes disclosure of certain financial information
that historically has not been recognized in the calculation of net loss. The
adoption of SFAS 130 had no impact on the Company's net loss or stockholders'
deficit. As of September 30, 1998, there were no differences between the
Company's net loss, as reported, and comprehensive loss.

          In March 1998, Statement of Position 98-1, "Accounting for the Cost of
Computer Software Developed or Obtained for Internal Use" ("SOP 98-1"), was
issued which provides guidance on applying generally accepted accounting
principles in addressing whether and under what conditions the costs of
internal-use software should be capitalized. SOP 98-1 is effective for all
transactions entered into in fiscal years beginning after December 15, 1998,
however earlier adoption is encouraged. The Company adopted the guidelines of
SOP 98-1 as of January 1, 1998, and the impact of such adoption was not material
to results of operations or cash flows for the quarter ended September 30, 1998.

          In June 1997, Statement of Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related Information" ("SFAS
131"), was issued which redefines how operating segments are determined and
requires disclosures of certain financial and descriptive information about a
company's operating segments. SFAS 131 is effective for fiscal periods beginning
after December 15, 1997 and its adoption may require additional disclosure of
the Company's historical financial data beginning with fiscal year ending
December 31, 1998.

          In June 1998, the FASB issued Statement of Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities." This Statement provides a comprehensive and consistent standard for
the recognition and measurement of derivatives and hedging activities. It
requires that an entity recognize all derivatives as either assets or
liabilities in the

OVERVIEW

Omnipoint reported a 1998 third quarter net loss of $157 million, an increase of
93%, or approximately $75.8 million over the same quarter in 1997. The year-to-
date net loss is $462.2 million, an increase of 129%, or $260.4 million over the
same period in 1997. The combination of added markets and improved coverage led
to an increase in subscribers of over 200% over this same period. At September
30, 1997, the company offered PCS services in New York and had just commenced
operations in Philadelphia and Atlantic City. One year later, at September 30,
1998, the company had built and launched services in over 20 additional cities
including Boston, Providence, Miami, West Palm, Albany, Syracuse, Hartford and
two joint ventures which offer services in Wichita, KS and several Pennsylvania
markets including Harrisburg, York, Lancaster and Reading.

The Company was the first PCS operator in the country to offer prepaid services,
reseller services, international calling and roaming and enhanced wireless
services such as real time stock quotes and wireless internet access. The
Company marketed to approximately 30 million pops at the beginning of the third 
quarter.  The Company's operations were affected by the following;

 .  September 1998 purchase of Urban Wireless' customer base.
 .  June 1998 $160 million credit facility with the Bank of America.
 .  June 1998 Connecticut and upstate New York market launches.
 .  June 1998 return of C-Block licenses reducing FCC debt and accrued interest
   by $337 million.
 .  May 1998 $252.2 million net proceeds from preferred stock issuance.
 .  March 1998 Boston and Miami market launches.
 .  February 1998 refinancing of $516 million interim credit facility with $750
   million credit facility.
 .  January 1998 $400 million credit facility for the Midwest market.
 .  September 1997 Philadelphia and Atlantic City market launches.
 .  July 1997 $352.5 million credit facility for the Boston and Miami markets.
 .  July 1997 $120 million credit facility for the Philadelphia and Dover
   markets.

RESULTS OF OPERATIONS

Revenues for the three months ended September 30, 1998 increased $28.4 million,
or 206% to $42.2 million, compared to revenues of $13.8 million for the three
months ended September 30, 1997. Year-to-date revenues increased $90.1 million,
or 318% to $118.4 million compared to revenues of $28.3 million in 1997. Service
revenues increased by $25 million, or 250% for the quarter and $82.5 million, or
530% year-to-date. The increase in service revenues is due to the continued
increase in the number of subscribers partially offset by a smaller decrease in
average revenue per subscriber. As a result of the increase in the customer
base, handset and accessories revenues increased $2.6 million for the quarter
and $8.9 million year-to-date. The larger customer base resulted from commercial
operations in the greater metro areas of New York, Miami, Boston, Philadelphia,
and several other Pennsylvania markets. The New York and Philadelphia metro area
coverages continue to expand, along with other less populated Pennsylvania
markets. The Boston and Miami metro areas began service in the last two weeks of
March 1998. Revenues for the first three quarters of 1997 were generated almost
exclusively from the New York metro area. The Company did not heavily advertise
in the New York metro market until February 1997. A

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                  -CONTINUED-
                                        
significant portion of the Company's customer base is prepay customers. The
Company is currently developing new methods to analyze and report on its prepay
customers and their usage characteristics. The Company's technology subsidiary 
("OTI") had revenues related to engineering services of $.7 million in the third
quarter of 1998 and $3.3 million year-to-date, compared to zero and $4.5 million
in license fees in the third quarter of 1997 and year-to-date 1997. OTI is party
to several engineering contract services agreements which are expected to
continue into 1999, but can be terminated under certain circumstances at either
party's option.

Total operating costs and expenses increased approximately $79.7 million, or
106% to $154.7 million for the three months ended September 30, 1998 and
increased approximately $252 million, or 139% to $433.3 million year-to-date.
Cost of service revenues were $29.4 million for the three months ended 
September 30, 1998, compared to $13.1 million for the three months ended
September 30, 1997. Year-to-date costs of service revenues were $89.6 million.
Included in the cost of services for the nine months ended September 30, 1998
was approximately $9.6 million of costs associated primarily with international
fraud committed during the first six months of 1998. The Company believes that
the sources of this fraud have largely been suppressed as of July 1998 and steps
have been taken with foreign carriers to limit future exposure to such fraud.
Excluding these fraud charges, the key causes for the increase in cost of
services are increased numbers of cell sites in operation from 729 at 
September 30, 1997 to 2,416 at September 30, 1998, expanded minutes of use, and
higher subscriber additions in the first three quarters of 1998 compared to the
first three quarters of 1997. The increase in these indicators results from the
Company offering commercial service in several markets in 1998, which were not
operational in 1997, including the Boston and Miami markets launched at the end
of the first quarter of 1998 and the Connecticut and upstate New York markets
launched in June 1998. Cost of handset and accessories revenues rose
approximately $.2 million to $17 million for the third quarter 1998 and 
$35.4 million to $69.4 million year-to-date. Handset and accessories costs
increased as a result of customer additions partially offset by a decrease in
unit costs in the nine months ended September 30, 1998 compared to the same
period in 1997.

Research and development expenses decreased by 28%, or approximately 
$1.7 million, to $4.3 million for the three months ended September 30, 1998,
compared to $6 million for the three months ended September 30, 1997. Year-to-
date research and development expenses decreased by 19%, or approximately $3.6
million, to $15.3 million. OTI is nearing completion of its work on the PCS
Fixed Access System, resulting in the expense reduction. Additionally, the
Company has entered into several joint development agreements that fund portions
of the Company's R&D expenses. The decrease was primarily due to a decrease in
R&D components and equipment purchases.

Sales, general, and administrative expenses relate to the Parent Company as well
as its two major operating subsidiaries, Omnipoint Communications Services, LLC
("OCS") and Omnipoint Technologies ("OTI"). General and administrative costs
include costs such as legal fees, patents, regulatory costs, auction and
negotiation expenses, office rents and incidentals, management information
systems, accounting and finance, bad debt, customer care and all payroll and
benefit costs other than those classified as research and development, those
related to cost of service, and those related to selling. Selling costs include
all marketing, advertising, promotion, telemarketing, market research, all
indirect, and direct distribution channels but excludes the costs of handsets
and accessories. Sales, general and administrative costs increased by
approximately $43 million and $107.2 million for the three and nine months ended
September 30, 1998, compared to the three and nine months ended September 30,
1997, or an increase of 160% and 164%, respectively. These increases are driven
by (i) an increase of over 200% in ending subscribers at September 30, 1998,
compared to September 30, 1997; (ii) increase in the number of distribution
outlets by 600% and (iii) an increase in the number of employees by 42% year
over year at September 30, 1998. As a result of the increases in subscribers and
employees, advertising and marketing, consulting, payroll and indirect
acquisition costs rose substantially for both the quarter and year-to-date 1998
over the same periods in 1997. Customer acquisition costs per subscriber
additions continued to decline for the three and nine months ended September 30,
1998. During October and early November, the Company undertook an analysis of 
the customer base it acquired from Urban Wireless as well as the Company's other
prepay accounts. The Company decided to reduce the subscriber count reported for
financial analysis purposes as of September 30, 1998 (relative to the 311,500
accounts as of that date, in the Home Location Register, which can actually 
make and receive calls) based on its assessment of the probability that a subset
of these prepays are unlikely to purchase coupons in the future. This resulted
in the Company reducing the total financial reported subscriber count by 5.8%
for the reduction in Urban Wireless accounts, by 6.4% for the reduction in the
Company's other prepays, and by approximately one percent for accounts
determined to have used fraudulent identities in prior periods. The Company also
undertook a significant effort to write off accounts receivable balances and
adjust its allowances for doubtful accounts. For the nine month period, this
resulted in the write off from the allowance for doubtful accounts of $19.4
million and thus an associated increase in this allowance by $25.5 million. The
company took other actions during the quarter to address these issues going
forward including installation of a customer profiling system, implementation of
an improved credit scoring system, implementation of barring procedures that
limit customers from making calls to certain foreign countries without
additional credit approvals, and an increase in its monitoring of subscriber
activity. Additionally, the rapid increase in subscribers and the pioneering of
prepay services led the Company to outsource temporary resources in several
areas, particularly in customer care support and billing. The Company built a
second customer care center in the third quarter which should reduce these
temporary outsource costs, and also introduced a new Intelligent Network ("IN")
platform to better monitor and handle the needs of prepay customers.

Depreciation and amortization increased approximately $21.5 million or 176% to
$33.7 million for the three months ended September 30, 1998 and $49.9 million,
or 141% to $85.2 million year-to-date. The increase is due to commencement of
depreciation on the network infrastructure equipment from recently launched
markets and amortization of FCC licenses when placed into commercial service.

As a result of the changes in revenues and operating costs and expenses
discussed above, the Company's loss from operations increased approximately
$51.3 million, or 84% to $112.5 million for the third quarter 1998 and 
$161.9 million, or 106% to $314.9 million year-to-date.

Equity in losses from joint ventures was $2.4 million and $6.5 million for the
third quarter of 1998 and year to date 1998, respectively, compared to zero
losses in 1997. The Company expects to continue to incur more losses from its
equity ownership interests in the Wichita and PCS One joint ventures as they
continue to build out their respective networks in Wichita and central
Pennsylvania.

Interest income decreased  to $2.1 million for the three months ended September
1998 and decreased $1.5 million to $9.3 million year-to-date. The decrease was
due to the use of cash and cash equivalents due to continued expansion and
equipment purchases for new and existing markets for the first three quarters of
1998 partially offset by interest from the proceeds of the May 1998 preferred
stock offering.

Interest expense increased by 101%, or approximately $22.3 million, to 
$44.4 million for the three months ended September 30, 1998 and 129%, or
approximately $77.1 million to $136.7 million year-to-date. The increase was due
to increased amounts outstanding from loans payable under financing agreements
and the FCC license obligations partially offset by capitalized interest. The
Company capitalized interest of $6.3 million year to date.

Loss before extraordinary item increased approximately $75.8 million, or 93% to
$157 million for the three months ended September 30, 1998 compared to 
$81.2 million for the three months ended September 30, 1997. Loss before
extraordinary item year-to-date 1998 was $451.1 million compared to 
$201.8 million for year-to-date 1997. This increase was primarily due to a
general increase in operating expenses, as well as an increase in net other
expenses associated with an increasing customer base and expansion of commercial
operations in existing and new markets.

In June 1998, the Company recognized an extraordinary loss of $11.1 million from
the return of C-block licenses. The Company returned fourteen licenses and
disaggregated four others. Interest associated with the disaggregated and
returned licenses was $4.1 million and $8.4 million for the nine months ended
September 30, 1998, respectively.

Net loss after extraordinary item increased approximately $75.8 million, or 93%
to $157 million for the three months ended September 30, 1998 compared to 
$81.2 million for the three months ended September 30, 1997. Net loss year-to-
date 1998 increased $260.4 million, or 129% to $462.2 million compared to 
$201.8 million for year-to-date 1997.

LIQUIDITY AND CAPITAL RESOURCES

For the nine months ended September 30, 1998, the Company reported an increase
in cash and cash equivalents of $84.7 million. This increase is primarily due to
advances of $980.6 million from various financing agreements and net proceeds of
$252.2 million from the issuance of 7% Cumulative Convertible Preferred Stock
("Preferred Stock") partially offset by the Company's additional activity
relating to the operation of the New York MTA network, several Pennsylvania
markets, the March 1998 launch of the Boston and Miami markets, the continued
buildout of the Company's core PCS networks, and interest expense associated
with the Company's related obligations. Operations of the Company for the first
nine months of 1998 have been financed through advances from various financing
agreements and through proceeds from the issuance of Preferred Stock.

Cash used in operations for the nine months ended September 30, 1998 increased
$261.8 million to $342.5 million due to ongoing operations and the launch of the
Miami and Boston markets in March, and the launch of the Connecticut and upstate
New York markets in June. Additionally, during the second quarter of 1998, the
Company identified losses due to fraudulent activities. The Company believes
that the international roaming fraud suffered has largely been eliminated and
steps have been taken with foreign carriers to limit future exposure to this
type of fraud.

Cash used in investing activities was $271.8 million for the nine months ended
September 30, 1998, compared to $352.5 million for the nine months ended
September 30, 1997. Investing activities consists primarily of $326.4 million
for purchases of PCS network infrastructure related items and lab equipment used
in engineering and manufacturing, and $9.5 million for investments in joint
ventures, partially offset by proceeds of $52.3 million net from short and long
term investments and $18.1 million net transactions associated with FCC
licenses.  Non-cash investing activities of the Company include the purchase of
Urban Wireless' customer base for approximately $3.7 million in net receivables
owed by Urban Wireless to the Company and a $.5 million credit issued to Urban
Wireless.

Cash provided by financing activities was $699.0 million for the nine months
ended September 30, 1998, compared to $303 million for the nine months ended
September 30, 1997. As of September 30, 1998, the Company had negative working
capital of approximately $97.8 million. At September 30, 1998, the Company had a
total borrowing capacity from its existing credit facilities of $460.9 million
comprised of immediate borrowing capacity of $125.9 million and future borrowing
capacity of $335 million based on qualified future orders for fixed asset
purchases. The Company is currently in negotiations for additional financing.
However, there can be no assurance that such financing will be obtained on
favorable terms, or at all. In February and August 1998, the Company used $52.3
million of proceeds from its escrow deposit account to pay interest on the 11
5/8% Senior and Series A Senior Notes. Non-cash financing activities of the
Company include the purchase of network infrastructure equipment from vendors of
$121 million and the $350 million refinancing of the interim credit facility.

In May 1998, the Company completed the private placement of 6,500,000 Depositary
Shares, each representing 1/20 of a share of 7% Cumulative Convertible Preferred
Stock. Each Depositary Share has a Liquidation Preference of $50, equivalent to
$1,000 per share of Preferred Stock. Net proceeds to the Company totaled
approximately $252.2 million net of offering costs and proceeds placed into the
Deposit Account.  Quarterly cash payments, funded through the Deposit Account,
commenced in August 1998 and will continue until May 2001.  Cumulative annual
dividends begin to accrue May 2001 unless the Company elects early termination
of the Deposit Account.  If the Company elects early termination of the Deposit
Account, dividends will begin to accrue immediately preceding the date of the
early termination.  In August 1998, the Company approved the quarterly cash
disbursement of $5.7 million, drawn from the Deposit Account to pay the holders
of Depositary Shares.

The Company's future capital requirements will depend upon many factors,
including the successful development of new markets, the extent and timing of
acceptance of the Company's services in the market, the progress of the
Company's research and development efforts, expansion of the Company's marketing
and sales efforts, the Company's results of operations and the status of
competitive products. The Company believes that access to capital and financial
flexibility are necessary to successfully implement its strategy. The Company
also believes the Permanent Facility, the BankAmerica Facility, the Ericsson MB
Facility, the Ericsson Philadelphia Facility, the amended Midwest Facility, and
the Preferred Stock offering, will be sufficient to fund anticipated operating
losses, and revised capital expenditures for the Company for the next several
months. The Company will require additional financing or expansion of existing
financing facilities to meet its needs. The Company is currently in negotiations
for additional and expanded financing with its vendors. Future financings are
expected to fund a portion of both future fixed asset purchases and working
capital requirements. However, there can be no assurance that such financing
will come to completion on favorable terms, or at all. To the extent that the
buildout of these networks are faster than expected, the costs are greater than
anticipated or the Company takes advantage of other opportunities, including
those that may arise through future FCC auctions, the Company will require
additional funding sooner to implement its business strategy.

The Company, through its subsidiary Omnipoint Venture Partners I, LLC. entered
into a joint venture agreement with D&E Communications Inc. ("D&E")
D&E/Omnipoint Wireless Joint Venture ("PCS One") entered into a financing
agreement with Northern Telecom, Inc. to help finance the buildout of its
central Pennsylvania markets. As a condition of the financing agreement, the
Company and D&E have a joint and several obligation to contribute funds not to
exceed the lesser of $50 million or the balance on the financing agreement in
the event of any default on the agreement by PCS One. Since the Company and D&E
have already jointly contributed $23.6 million to PCS One which is greater than
the amount drawn on the the facility, the maximum remaining obligation was zero
as of September 30, 1998. If current ownership percentages of the joint venture
are maintained, the Company's anticipated future contribution to meet this
obligation would be less than $14 million.

In June 1998, Omnipoint MB Holdings, LLC ("OMB"), an indirect, wholly-owned
subsidiary of the Company, entered into a $160 million credit facility agreement
with Bank of America International Limited (the "BankAmerica Facility"). The
BankAmerica Facility replaced $150 million of credit under the July 1997
Ericsson MB Facility. Proceeds from the BankAmerica Facility are available to
finance equipment purchases for the Miami and Boston markets. Interest on such
amount is payable quarterly in arrears or at the end of each applicable interest
period as provided in the BankAmerica Facility. Principal amortization on the
facility begins no earlier than January 2000 with a final maturity due no
earlier than July 2004. EXPORTKREDITNAMNDEN ("EKN"), the Swedish Export Credit
Guaranty Board, guarantees a portion of the outstanding balance of the
BankAmerica Facility. Contemporaneously with the closing of the BankAmerica
Facility, the Ericsson MB Facility was amended and restated to, among other
things eliminate the $150 million portion that was replaced by the BankAmerica
Facility. Ericsson was granted a five-year exclusive right to supply network
equipment for the Boston and Miami markets. As of September 30, 1998, the
Company had $104.8 million outstanding under the BankAmerica Facility.

Under the terms of the BankAmerica Facility, the Company is subject to certain
financial and operational covenants, including but not limited to restrictions
on the ability to pay dividends and level of indebtedness. The BankAmerica
Facility ranks pari passu with the Ericsson MB Facility and is collateralized by
substantially all the assets of OMB and each of the license and operating
subsidiaries for the Boston and Miami markets, including a pledge of all capital
stock of each such license and operating subsidiaries as well as capital stock
of OMB.

The FCC issued a reconsideration order (the "Order") which went into effect
April 1998, allowing companies holding C-block Personal Communications Services
licenses several options to restructure their license holdings and associated
obligations. The Company elected under the amnesty option of the order to return
14 Basic Trading Area ("BTA") licenses. The Company also elected to forgo the
respective 10 percent deposits on these licenses in return for the option to re-
bid on the licenses. Thus with respect to amnestied licenses, the Company
recognized a reduction of $110.5 million in debt and $13.4 million in accrued
interest. The net book value of the fully returned licenses was $139.1 million.

The Company also elected a second option, the disaggregation option, to return
half the spectrum on BTAs covering the Philadelphia, Pa., Reading, Pa., Dover,
De., and Atlantic City, N.J. markets. Under the disaggregation option, the
Company retains 15 MHz in each of the four BTAs while returning 15 MHz. The
disaggregation extinguishes 50 percent of the outstanding debt on the licenses
and prohibits the Company from owning or re-bidding on the licenses for two
years from the date of the re-auction. As a result of the disaggregation, the
Company recognized a reduction of $131.8 million in debt, and $26.4 million in
accrued interest. The net book value of the disaggregated 50 % of the licenses
was $156.9 million.

On a nominal basis, the two elections reduced the Company's debt and accrued
interest by approximately $337 million. Additionally, the Company will receive
approximately a $2.7 million refund for FCC interest previously paid on returned
licenses. As a result of the amnesty and disaggregation elections, the Company
recognized an extraordinary loss of $11.1 million in the second quarter.

In February 1998, Omnipoint Communications Inc. ("OCI"), an indirect, wholly-
owned subsidiary of the Company, refinanced a $516 million interim credit
facility (the "Interim Credit Facility") with a $750 million credit facility
with DLJ Capital Funding Inc. ("DLJ") and certain other parties (the "Permanent
Credit Facility" or the "Agreements") pursuant to (a) a $595 million credit
facility agreement and (b) a $155 million note purchase agreement. The $595
million credit facility agreement may be increased under certain circumstances.
In February 1998, OCI borrowed $450 million (of which $295 million was funded
under the credit facility agreement and $155 million was funded under the note
purchase agreement). A portion of the proceeds, approximately $351.6 million,
was used to fully repay outstanding borrowings including accrued interest on the
Interim Credit Facility. An additional $50 million and $250 million were
borrowed under the Permanent Credit Facility in March and April 1998,
respectively. Also during the second quarter, certain holders, at their option,
converted $44.5 million of the notes purchased under the note purchase agreement
into a portion of the credit facility. Under the terms of the Agreements, OCI
and the Company are subject to certain financial and operational covenants,
including restrictions on the Company's ability to pay dividends, level of
indebtedness, and certain other financial maintenance requirements. The
Agreements are collateralized by substantially all of the assets of OCI and its
license subsidiary, including a pledge of all capital stock and such license
subsidiary, as well as 95.6% of the capital stock of OCI. The obligations of OCI

                                  -CONTINUED-
                                        
Agreements are supported by guarantees from Omnipoint Holdings, Inc., Omnipoint
Investments Two, Inc. and Omnipoint PCS, Inc., each a direct, wholly-owned
subsidiary of the Company, and collateralized by substantially all of their
respective assets. The principal amount of the Agreements is payable in
installments, which began June 1998, with a final payment due February 2006.
Interest on such amount is payable quarterly in arrears or at the end of an
applicable interest period as provided in the Agreements. As of September 30,
1998, the Company had approximately $746.3 million outstanding under the
Permanent Credit Facility.

In January 1998, the Company, through an indirect, wholly-owned subsidiary,
Omnipoint Midwest Holdings LLC ("OMWH"), entered into a credit facility
agreement (the "Midwest Facility") with Northern Telecom Inc. ("NorTel") for up
to $400 million to provide financing to OMWH. Concurrent with the NorTel 
financing agreement with PCS One, the Midwest Facility was amended to reduce the
amount available from $400 million to $360 million. The Midwest Facility will
finance the buildout of networks in certain Midwest markets including Detroit,
Indianapolis, and certain other designated markets. The Midwest Facility
provides that up to $85 million is available to OMWH for any purpose, including
an inter-company loan to the Company. The Company at its sole option can
repay the $85 million portion of the loan in either cash or the Company's Common
Stock under certain conditions. In August 1998, the Company repaid the remaining
balance of approximately $14.5 million outstanding under the Midwest Facility.
The $14.5 million was originally used to purchase network infrastructure
equipment for a market which was later contributed to joint ventures of the
Company. Subsequent to September 30, 1998, the Company drew $42.5 million from
the Midwest Facility.

Under the terms of the Midwest Facility, OMWH is subject to certain financial
and operational covenants, including but not limited to restrictions on OMWH's
ability to pay dividends and level of indebtedness. The Midwest Facility is
collateralized by substantially all the assets of OMWH and its license and
operating subsidiaries for the Midwest and certain other designated markets,
including a pledge of all capital stock of each such license and operating
subsidiary, as well as all capital stock of OMWH owned by an indirect, wholly-
owned subsidiary of the Company, Omnipoint PCS Entrepreneurs Two, LLC (" OPCS
Two LLC").

The $85 million portion of the Midwest Facility which has no required
amortization, matures in March 2008. Interest on such portion is payable semi-
annually (which interest may be accreted until March 2004). The remaining
portion of the Midwest Facility which is available to finance equipment
purchases from NorTel and certain eligible third party expenses is payable in
installments beginning in 2002, with a final payment due December 2006. Interest
on such amount is payable quarterly with regard to base rate loans and at the
end of an applicable interest period with regard to LIBOR rate loans. The
Midwest Facility was provided in conjunction with the amendment to the Northern
Telecom Supply Agreement, wherein OMWH, together with other affiliates of the
Company, agreed to purchase up to $210 million of equipment and services from
Northern Telecom over a four-year period and to purchase GSM PCS network
equipment exclusively from Northern Telecom in the Midwest markets.

In August 1997, Omnipoint MB Holdings, LLC, an indirect, wholly-owned subsidiary
of the Company, entered into a credit facility agreement with Ericsson Inc. to
provide financing to the Company for up to $352.5 million for the purpose of
financing the buildout of networks in the Boston and Miami markets, (the
"Ericsson MB Facility"). The Ericsson MB Facility finances purchases and
installations of telecommunications equipment, engineering services, certain
related construction costs, third-party equipment and other expenses and up to
$100 million for the unrestricted use of OMB, including making a loan to the
Company. The Ericsson MB Facility provides the immediate availability of $202.5
million, of which $100 million was funded to OMB at closing. The Company at its
sole option can repay or prepay in whole or in part interest or principal under
the $100 million portion of the loan in cash or with the Company's Common Stock
under certain conditions. The remaining $150 million was replaced with a $160
million BankAmerica Facility partially guaranteed by EKN in June 1998. In
connection with the BankAmerica Facility, the Company amended and restated the
Ericsson MB Facility and granted Ericsson a five-year exclusive right to supply
network equipment for the Boston and Miami markets. As of September 30, 1998,
the Company had $186.1 million outstanding under the Ericsson MB Facility.

Under the terms of the Ericsson MB Facility, OMB is subject to certain financial
and operational covenants including restrictions on OMB's ability to pay
dividends, restrictions on indebtedness and certain financial maintenance
requirements. Additionally, the Ericsson MB Facility provides that, among other
events, the failure of OMB to pay when due amounts owing to the FCC shall
constitute an event of default. The Ericsson MB Facility is collateralized by
substantially all of the assets of OMB and each of the license and operating
subsidiaries for the Boston and Miami markets, including a pledge of all capital
stock of each such license and operating subsidiaries as well as capital stock
of OMB.

The principal amount of portions of the Ericsson MB Facility financing equipment
purchases from Ericsson, and certain eligible third party provided costs, is
repayable in installments beginning 2001, with a final payment due August 2006.
Interest on such portion of the loan is payable quarterly (of which portions of
the loan proceeds are available to finance such interest payments). The $100
million portion funded at closing has no required principal amortization, and
matures August 2007. Interest on such portion is payable semi-annually (of which
interest may be accreted until August 2003).

In July 1997, OPCS Philadelphia Holdings, LLC ("OPCS"), an indirect, wholly-
owned subsidiary of the Company, entered into a credit facility agreement with
Ericsson to provide financing to OPCS for up to $120 million for the purpose of
financing the buildout of networks in the Philadelphia and Dover markets (the
"Ericsson Philadelphia Facility"). Under the terms of the Ericsson Philadelphia
Facility, OPCS is subject to certain financial and operational covenants
including restrictions on OPCS's ability to pay dividends, restrictions on
indebtedness and certain other financial maintenance requirements. Additionally,
the Ericsson Philadelphia Facility provides that, among other events, the
failure of OPCS to pay when due amounts owing to the FCC shall constitute an
event of default. The Ericsson Philadelphia Facility is collateralized by
substantially all of the assets of OPCS and each of the license and operating
subsidiaries for the Philadelphia and Dover markets, including a pledge of all
capital stock of each such license and operating subsidiary as well as capital
stock of OPCS. As of September 30, 1998, the Company had approximately $114
million outstanding under the Ericsson Philadelphia Facility.

The principal amount of the Ericsson Philadelphia Facility is payable in twenty
quarterly installments beginning in the year 2001, with a final payment due
December 2005. Interest on such amount is payable quarterly in arrears with
regard to base rate loans and at the end of an applicable interest period with
regard to LIBOR loans (of which a portion of the loan proceeds are available to
finance such interest payments).

In November 1998, the Company reached a settlement with the United States 
Department of Justice ("DOJ") in the form of a civil consent decree that
involves no monetary penalties. See U.S.v. Omnipoint Corp., Case No. 
1:98CV02750 (D.D.C. filed Nov. 10, 1998.) The consent decree ended an
investigation into certain bidding techniques that a number of bidders employed
during the FCC's PCS license auctions. The FCC had dropped its independent
investigation into the same bidding techniques several months earlier after a
lengthy review of Omnipoint's bidding, as well as that of many other bidders.
The Company strongly believes that it did nothing wrong during any FCC auction,
and that had it chosen to fight the DOJ's assertions in court, that the Company
would have prevailed. In agreeing to the civil consent decree, the Company does
not admit to any wrong doing, nor was it found guilty of any wrong doing. The
decree does not impose any penalties, nor does it prevent the Company from
participating in any future FCC auctions. The civil consent decree is subject to
final approval by the Court, which the Company currently expects in early 1999.

YEAR 2000 COMPLIANCE

Many of the world's computer systems (including those in non-information
technology equipment and systems) currently record years in a two-digit format.
If not addressed, such computer systems will be unable to properly interpret
dates beyond the year 1999, which could lead to business disruptions in the U.S.
and internationally (the "Y2K" issue).  A number of the Company's technology
systems are affected by the Y2K issue.  To ensure that the Company will be Y2K
compliant before the new millenium, the Company formed a Y2K compliance team in
the fourth quarter of 1997 and allocated corporate resources to determine the
extent of non-compliance with the Y2K issue and to formulate a Y2K compliance
plan.  Since then, the Company has been reviewing its embedded technology and
infrastructure equipment, as well as non-embedded technology equipment to
identify those that contain two-digit year codes, and is in the process of
upgrading its infrastructure and corporate facilities to achieve Y2K compliance.
In addition, the Company is actively working with its suppliers to assess their
compliance and remediation efforts and the Company's exposure to them.  The
Company is proceeding on schedule to be Y2K compliant by the second quarter of
1999.

The Company is focusing on three major areas of concern for the Y2K issue:
embedded technology and infrastructure equipment, non-embedded technology
equipment and third party suppliers compliance.  The Y2K compliance team created
a five stage process for becoming Y2K compliant.  The five process stages are
(1) compiling a complete inventory of all date sensitive technology equipment;
(2) prioritizing systems affected based on  estimated time to compliance, vendor
and maintenance schedule; (3) performing modification of affected systems; (4)
completing testing of modified systems; and (5) performing implementation of
modified systems.  The Company has generally completed the inventory of its date
sensitive technology equipment and is in various stages of  prioritizing and
modifying a number of the systems.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                  -CONTINUED-
                                        
EMBEDDED TECHNOLOGY AND INFRASTRUCTURE EQUIPMENT. The embedded technology and
infrastructure equipment area of concern consists primarily of the hardware
portion of the switching platforms and network surveillance equipment. Much of
this equipment, specifically the switching platforms, is purchased from third
party vendors and has a yearly maintenance contracts. The maintenance contracts
include regular software and hardware upgrades that should automatically bring
the equipment into Y2K compliance. The Company is dependent on those third
parties to assess the impact of the Y2K problem on the technology they have
supplied and to take any necessary corrective action. All corrective action
taken by these third parties is covered under maintenance contracts and would be
part of regularly scheduled maintenance.  The Company is monitoring the progress
of these third parties and selectively conducting tests to determine whether
they have accurately assessed the problem and taken corrective action.  All
embedded technology systems and infrastructure equipment are scheduled to be Y2K
compliant by June 30, 1999.  In addition, in order to protect against the
acquisition of additional non-compliant products, the Company now requires
suppliers to warrant that products sold or licensed to the Company are Y2K
compliant.

NON-EMBEDDED TECHNOLOGY EQUIPMENT.  Non-embedded technology systems include
predominately applications software and interfacing software.  Much of this
equipment has previously been upgraded to Y2K compliance through software
upgrades and the purchase of new systems.  Future expenditures in this area will
not be material.  Nonetheless, the Company is in the process of prioritizing
those systems that are not Y2K compliant and upgrading or replacing non-
compliant systems.  All non-embedded technology systems are scheduled to be Y2K
compliant by June 30, 1999.

THIRD PARTY SUPPLIERS.  The Company is currently in the process of  prioritizing
its critical suppliers  and communicating with them about their plans and
progress in addressing the Y2K  issue. Detailed evaluations of the most critical
third parties have been initiated.  These evaluations will be followed by the
development of contingency plans, commencing in the fourth quarter of 1998, with
completion expected by June 30, 1999.

RISK AND CONTINGENCY PLAN.  There are many risks associated with the Y2K issue,
including the possibility of a failure of the Company's signal, computer, and
non-information technology systems.  Such failures could have a material adverse
effect upon the Company and may cause systems malfunctions, signal loss,
incorrect or incomplete transaction processing, the inability to reconcile
accounting books and records, and the inability for the Company to manage its
business.  In addition, even if the Company successfully becomes Y2K compliant,
it can be materially and adversely affected by failures of third parties to
become Y2K compliant.   The failure of third parties with which the Company has
financial or operational relationships such as network maintenance contractors,
roaming partners, handset and accessory providers, financial institutions,
payroll contractors, regulatory agencies and utility companies, to become Y2K
compliant in a timely manner could result in material adverse effects on the
Company's results of operations.

The Company is currently working diligently to become Y2K compliant by June 30,
1999.  However, there can be no assurance that the Company will be successful in
taking corrective action in a timely manner.  The Company has started to develop
contingency plans with regard to its key technology systems, although there can
be no assurance that these contingency plans will successfully avoid a service
disruption.  The Company intends to document Y2K contingency plans during 1999
as part of its Y2K risk mitigation efforts.

COSTS.  Total costs incurred to date specifically associated with becoming Y2K
compliant have been less than $1 million.  The total estimated  specific costs
of becoming Y2K compliant is estimated to be less than $10 million.  Non-
specific costs associated with becoming Y2K compliant, such as maintenance
contracts that automatically upgrade certain technology components within a
larger upgrade have not been included in this estimate.  These costs, considered
by the Company to be a normal recurring expense, will be included in the Y2K
compliance costs once the specific Y2K components can be identified and
allocated.

The Company's expectations about future costs and timely completion of its Y2K
modifications are subject to uncertainties that could cause actual results to
differ materially from what has been discussed above.  Factors that could
influence the amount of future costs and the effective timing of remediation
efforts include the success of the Company in identifying embedded technology
and infrastructure equipment as well as non-embedded equipment that contain two-
digit year codes, the nature and amount of programming and testing required to
upgrade or replace each of the affected systems and equipment, the nature and
amount of testing, verification, the rate and magnitude of related labor costs,
and the success of the Company's suppliers, in addressing the Y2K issue.

RECENT ACCOUNTING PRONOUNCEMENTS

Effective January 1, 1998, the Company adopted Statement of Financial Accounting
Standards No. 130 ("SFAS 130"), "Reporting Comprehensive Income". SFAS 130
requires the reporting of comprehensive income (loss) in addition to net income
(loss) from operations. Comprehensive income is a more inclusive reporting
methodology that includes disclosure of certain financial information that
historically has not been recognized in the calculation of net loss. The
adoption of SFAS 130 had no impact on the Company's net loss or stockholders'
deficit. As of September 30, 1998, there were no differences between the
Company's net loss, as reported, and comprehensive loss.

In March 1998, Statement of Position 98-1, "Accounting for the Cost of Computer
Software Developed or Obtained for Internal Use" ("SOP 98-1"), was issued which
provides guidance on applying generally accepted accounting principles in
addressing whether and under what conditions the costs of internal-use software
should be capitalized. SOP 98-1 is effective for all transactions entered into
in fiscal years beginning after December 15, 1998, however earlier adoption is
encouraged. The Company adopted the guidelines of SOP 98-1 as of January 1,
1998, and the impact of such adoption was not material to results of operations
or cash flows for the quarter ended September 30, 1998.

In June 1997, Statement of Financial Accounting Standards No. 131, "Disclosures
about Segments of an Enterprise and Related Information" ("SFAS 131"), was
issued which redefines how operating segments are determined and requires
disclosures of certain financial and descriptive information about a company's
operating segments. SFAS 131 is effective for fiscal periods beginning after
December 15, 1997 and its adoption may require additional disclosure of the
Company's historical financial data beginning with the fiscal year ending
December 31, 1998.

In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133, "Accounting for Derivative Instruments and Hedging Activities." This
Statement provides a comprehensive and consistent standard for the recognition
and measurement of derivatives and hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. The
Statement is effective for fiscal years beginning after June 15, 1999. The
Company will adopt the new standard by January 1, 2000. Management believes this
statement will not impact the Company's financial statements.
