                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


                        SEPTEMBER 30, 1999 (UNAUDITED)


NOTE 1: THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES


     BASIS OF PRESENTATION

     The consolidated financial information includes the accounts of BTI
Telecom Corp. and its wholly owned subsidiaries (the "Company" or "BTITC")
after elimination of intercompany transactions. The consolidated interim
financial statements of BTITC included herein are unaudited and have been
prepared in accordance with generally accepted accounting principles ("GAAP")
for interim financial reporting and in accordance with Securities and Exchange
Commission rules and regulations. Certain information and footnote disclosures
normally included in financial statements prepared in accordance with GAAP have
been condensed or omitted pursuant to such rules and regulations. In the
opinion of management, the financial statements reflect all adjustments (all of
which are of a normal and recurring nature) that are necessary to present
fairly the financial position, results of operations and cash flows for the
interim periods. The results for any interim period are not necessarily
indicative of the results for any other period. These financial statements
should be read in conjunction with the Company's Annual Report on Form 10-K for
the year ended December 31, 1998 and the Company's Registration Statement on
Form S-1 filed with the SEC on July 16, 1999.

     Preparation of the financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities and disclosure of contingent assets and liabilities
at the date of the financial statements, and the reported amounts of revenues
and expenses during the reporting period. Actual results could differ from
those estimates.

     Certain amounts in the September 30, 1998 Financial Statements have been
reclassified to conform to the September 30, 1999 presentation.


     In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use" ("SOP 98-1"), which
requires the capitalization of certain costs incurred in connection with
developing or obtaining software for internal use. The Company adopted the
provisions of SOP 98-1 in its financial statements as of January 1, 1999.

     In April 1998, the AICPA issued Statement of Position 98-5, "Reporting on
the Costs of Start-Up Activities" ("SOP 98-5"), which requires that costs
related to start-up activities be expensed as incurred. The Company adopted the
provisions of SOP 98-5 in its financial statements as of January 1, 1999. Prior
to 1999, the Company expensed start-up costs and therefore, the adoption of SOP
98-5 will have no impact on the Financial Statements.


     EQUIPMENT, FURNITURE AND FIXTURES

     During the fourth quarter of 1997, the Company commenced construction on
certain capital projects, including its fiber optic network. Interest costs
associated with the construction of capital assets are capitalized. The total
amount capitalized for the nine-month periods ended September 30, 1999 and 1998
was $1.1 million and $1.5 million, respectively.

     Costs associated with the fiber optic network are classified as
"Construction in Progress" in the accompanying consolidated balance sheets.
Upon completion of network segments, these costs will be transferred into
service and depreciated over their useful lives.


NOTE 2: LONG-TERM DEBT

     Effective June 30, 1998, the Company amended and restated its $60.0 million
revolving credit facility to provide a $30.0 million revolving credit facility
and a $30.0 million capital expenditure facility (the "GE Capital Facilities").
Borrowings under the GE Capital Facilities are limited to a percentage of
eligible accounts receivable and eligible capital expenditures, respectively, as
defined in the loan agreement. The GE Capital Facilities are secured by the
grant of a first security interest in substantially all of the Company's assets
excluding the fiber optic network and related equipment and a second security
interest in the Fiber Optic Network and related equipment. The GE Capital
Facilities bear interest, at the Company's option, at either the 30, 60 or
90-day LIBOR rate or the prime rate, plus an applicable margin. This margin
varies, based on the Company's financial position, from 0.0% to 1.25% for
borrowings under the prime rate option and from 1.75% to 3.0% for borrowings
under the LIBOR option. The Company is also required to pay a fee of 0.375% per
year on the unused commitment. As of September 30, 1999, there was a total of
$28.1 million outstanding under the GE Capital Facilities, in addition to $0.1
million in outstanding letters of credit. The GE Capital Facilities contain
various financial covenants with which the Company must comply on a monthly and
quarterly basis.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 2: LONG-TERM DEBT -- (Continued)

      On September 8, 1999, the Company obtained a credit facility from Bank of
America (the "Bank of America Facility"). Availability under the Bank of America
Facility is based on the amount of fiber optic network purchased from Qwest
Communications (see note 4) and purchases of related equipment from Nortel
Networks, Inc. Availability under the Bank of America Facility is limited to
$37.5 million until the Company raises at least $100.0 million in additional
equity financing, at which time the Bank of America Facility's availability will
increase to $60 million. Borrowings are secured by a first security interest in
the fiber optic network and related equipment and will bear interest, at the
Company's option, at either the 30, 60 or 90-day LIBOR rate or the prime rate
plus an applicable margin. This margin varies, based on the Company's financial
position and additional equity issuances, from 1.00% to 2.50% for borrowings
under the prime rate option and from 2.00% to 3.50% for borrowings under the
LIBOR option. The Company is also required to pay of fee of 1.5% per year on the
unused commitment. As of September 30, 1999, there was a total of $26.0 million
outstanding under the Bank of America Facility. The Bank of America Facility
contains various financial covenants with which the Company must comply on a
monthly and quarterly basis. Under The Bank of America Facility the Company also
granted Bank of America a second security interest in substantially all the
assets of the Company.

NOTE 3: INCOME TAXES

     In September 1997, the Company converted from S corporation to C
corporation status for federal and state income tax purposes. As a result, the
Company became fully subject to federal and state income taxes. For the
three-month and nine-month periods ended September 30, 1999 and 1998, the
Company generated net losses. The Company has established a valuation allowance
for the net deferred tax assets associated with these net operating losses. As
such, there was no impact on the results from operations for net operating
losses generated during the three-month and nine-month periods ended September
30, 1999 and 1998. The Company will reduce the valuation allowance when, based
on the weight of available evidence, it is more likely than not that some
portion or all of the deferred tax assets will be realized.


NOTE 4: COMMITMENTS

     During 1997, the Company signed a contract for the indefeasible right to
use certain optical fibers in a communications system. Commitments to purchase
optical fibers under this contract total approximately $51.0 million, $42.3
million of which was fulfilled through September 30, 1999. Costs associated
with fiber optic network segments under construction are classified as
"Construction in progress" in the accompanying consolidated balance sheets.
Upon completion of network segments, these costs will be transferred into
service and depreciated over their useful lives. The remaining commitments
extend through the end of 1999. In addition, the Company has made certain other
commitments for the purchase of equipment in connection with its capital
program.


NOTE 5: CONTINGENCIES

     On September 14, 1998, Gulf Communications, LLC (the "Plaintiff") filed a
lawsuit which is now pending in the United States District Court for the
Northern District of Texas. The Plaintiff alleges breach of contract, negligent
misrepresentation and fraud in the inducement. The Plaintiff seeks monetary
damages, although a specific amount has not been plead. The Company is
vigorously defending this litigation. Because discovery is ongoing, and due to
the uncertainties inherent in the litigation process, the Company is unable to
predict the likelihood of an unfavorable outcome. The costs of defense and
final resolution of this issue could result in the Company recording an
obligation which could have an adverse effect on the Company.

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

     The matters discussed throughout this Form 10-Q, except for historical
facts contained herein, may be forward-looking in nature, or "forward-looking
statements." Actual results may differ materially from the forecasts or
projections presented. Forward-looking statements are identified by such words
as "expects," "anticipates," "believes," "intends," "plans" and variations of
such words and similar expressions. BTI Telecom Corp. and its wholly owned
susidiaries (the "Company") believes that its primary risk factors include, but
are not limited to: high leverage; the ability to service debt; significant
capital requirements; ability to manage growth; business development and
expansion risks; competition; and changes in laws and regulatory policies. Any
forward-looking statements in the September 30, 1999 Form 10-Q should be
evaluated in light of these important risk factors. For additional disclosure
regarding risk factors refer to the Company's Registration Statement on Form
S-1 as filed with the Securities and Exchange Commission (File No. 333-83101).


BUSINESS OF THE COMPANY

     OVERVIEW

     BTI Telecom Corp., which began operations in 1983 as Business Telecom,
Inc. ("BTI"), is a provider of telecommunications services in the southeastern
United States. We currently offer integrated telecommunications services,
including long distance, local, data, Internet access and other enhanced
services, primarily to small and medium-sized business customers. In addition,
we offer wholesale telecommunications services, including switched, dedicated
access, special access and prepaid calling card services, primarily to
telecommunications carriers. We also market high bandwidth services on our
fiber optic network. We currently have sales offices in 23 markets located
primarily in the southeastern United States.

     We operate long distance switching centers in Atlanta, Dallas, New York,
Orlando and Raleigh, and began offering local exchange services in November
1997 primarily on a resale basis. However, we are in the process of
transitioning customers onto our own facilities and have installed Lucent
5E2000 local switches in Raleigh, Charlotte, Greensboro and Wilmington, North
Carolina; Columbia and Greenville, South Carolina; Orlando and Jacksonville,
Florida; and Atlanta, Georgia. We are currently installing a local switch in
Tampa, Florida. In addition to these local switches, we have co-located digital
loop carriers in 48 incumbent local exchange carrier central offices in order
to provide more cost-effective local services to our business customers. These
co-locations should also facilitate our future data service product offerings,
as they should allow for more rapid deployment of digital subscriber line (DSL)
services. As of September 30, 1999 we had sold over 84,000 access lines, of
which 75,300 were in service. Approximately 23% of these lines in service were
facilities-based. In addition, over 98% of BTI's access lines are non-ISP
lines.

     We operate a fiber optic network, consisting of owned and leased
transmission capacity, concentrated in the southeastern United States. In
October 1997, we entered into an agreement with Qwest Communications to acquire
an indefeasible right to use approximately 3,300 route miles of fiber optic
network from New York to Miami and Atlanta to Nashville. As of September 30,
1999 we had over 1,100 route miles of this network in service and expect the
network to be substantially completed during the first quarter of 2000. In
addition to carrying our own traffic, this network allows us to market excess
fiber capacity to other telecommunication companies. We have also installed
seven frame relay switches within our network to enhance our current and future
data service offerings.

     On July 16, 1999, we filed a Registration Statement on Form S-1 (File No.
333-83101) with the SEC for a public offering of approximately $125,000,000
worth of our Common Stock (our "initial public offering"). In addition to the
ongoing monitoring of public market conditions with its investment bankers, BTI
has closely watched the recent significant investments within the
telecommunications sector by private equity funds. As a result, in September,
BTI retained an investment bank to evaluate private equity placement
opportunities.


RESULTS OF OPERATIONS
FOR THE THREE MONTHS ENDED SEPTEMBER 30, 1999 AND 1998

     REVENUE

     Revenue for the third quarter of 1999 was $72.1 million, representing an
increase of 39.4% as compared to the same period in 1998. The $20.4 million
increase during the three months ended September 30, 1999 as compared to the
same period in 1998 is attributable to increases in integrated retail voice
services revenues of $6.0 million, wholesale services revenues of $11.7 million
and data services revenue of $2.7 million. Retail services revenue, while up
from the same period in 1998, was adversely affected by two Southeastern
hurricanes during September 1999. The increase in integrated retail voice
services revenue consisted primarily of increases in local services revenue of
$6.7 million, partially offset by decreases in traditional long distance revenue
of $0.7 million. The decrease in long distance revenue primarily resulted from
price compression, as third quarter 1999 retail long distance minutes actually
increased 7.5% over the same period in 1998. In addition, we are selling a
bundled retail product which combines lower long distance rates with
facilities-based local service to strengthen sales of our facilities-based local
product. Overall gross margins on these customers are maintained or improved,


                                       8
<PAGE>

despite the fact this bundled product includes a lower rate per minute for long
distance. The improved margins are achieved because we avoid access charges
on long distance calls placed by our customers and have the ability to bill
other telecommunication carriers access charges for the use of our local
network. The success of this concept is demonstrated by the fact that we are
providing long distance service to over 92% of our local service customers.
Local services revenue increased from 11.9% of integrated retail voice services
in the third quarter of 1998 to 27.7% for the same period in 1999. Wholesale
services revenue was up largely due to the increase in sales of prepaid calling
card services of $13.1 million over the third quarter 1998, which was partially
offset by decreases in switched wholesale services of $1.4 million. The increase
in data services revenue is attributable to the additional Internet, frame relay
and private line services we are providing to business customers as well as
other telecommunication carriers.


     COST OF SERVICES

     Cost of services represented 68.9% of revenue for the three-month period
ended September 30, 1999, as compared to 70.8% for the same period in 1998. The
lower cost of services percentage for the three-month period ended September 30,
1999 reflects the effects of various improvements in our cost components,
partially offset by changes in our revenue mix. The changes in our revenue mix
consisted of increases in integrated retail voice services accompanied
by larger increases in wholesale services revenue. Within wholesale services,
overall margins on our prepaid calling card services decreased due to changes in
user calling patterns. However, we have implemented pricing changes on this
product that should improve its margins by the first quarter of 2000. In
addition, as we have installed more local switches and converted local resale
customers to facilities-based services, our local service margins have improved.

     Expansion of our fiber optic network, the continuing effect of access
charge reforms and rate decreases from our underlying service providers have
also improved our margin percentages. In addition to adding revenues from
capacity sales to other telecommunication providers, our fiber optic network
provides for cost savings throughout the network. However, cost savings from our
fiber optic network were less than originally anticipated during the third
quarter due largely to vendor delays in the delivery of additional network
segments. During the three months ended September 30, 1999 we deployed 260 miles
of our fiber optic network, increasing our total fiber route miles to 1,200.


     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Selling, general and administrative expenses in the third quarter of 1999
were $22.2 million, or 30.9% of revenue, as compared to $17.2 million, or 33.4%
of revenue, in the same period in 1998. The increase in the amount of selling,
general and administrative expenses is largely attributable to the significant
investments in human resources and increased marketing and advertising efforts
associated with the continued expansion of our local and data services and
deployment of our fiber optic network. However, our revenue growth has outpaced
our spending in these areas resulting in the decrease in selling, general and
administrative expenses as a percent of revenue. The investments in
infrastructure and support provide us with the ability to continue to expand
into new markets, maximize customer retention and provide for growth.

     Depreciation and amortization was $5.2 million in the three months ended
September 30, 1999, representing an increase of 69.8% over the same period in
the previous year. This increase is primarily due to capital expenditures
related to the expansion of our network operations centers, fiber network and
support infrastructure to accommodate increased traffic volume and expanded
service offerings.


     OTHER INCOME (EXPENSE)

     Interest expense was $7.0 million for the three-month period ending
September 30, 1999, compared to $6.3 million in the same period of the previous
year. The $0.7 million increase is primarily attributable to increased
borrowings under our credit facilities during the third quarter of 1999
compared to the third quarter of 1998. In addition to interest expense
recognized during the quarter, we capitalized $0.5 million of interest expense
associated with the construction of our network in the three months ended
September 30, 1999, as compared to $0.4 million for the same period in 1998.

     Interest income decreased from $1.2 million in the three-month period
ended September 30, 1998 to $0.6 million in the three months ended September
30, 1999. This decrease resulted from lower restricted and non-restricted cash
balances during 1999.


     EBITDA

     EBITDA consists of income (loss) before interest, income taxes,
depreciation, amortization and other non-cash charges. EBITDA is a common
measurement of a company's ability to generate cash flow from operations.
EBITDA is not a measure of financial performance under generally accepted
accounting principles and should not be considered an alternative to net income
as a measure of performance or to cash flows as a measure of liquidity.


                                       9
<PAGE>

     EBITDA for the three months ended September 30, 1999 was $0.2 million.
This represents an improvement of $2.4 million over the EBITDA loss of $2.2
million during the same period in 1998. The increase in EBITDA during 1999 was
attributable to the overall revenue and gross margin improvement over the same
period in 1998. These improvements were partially offset by the effects of two
hurricanes in September 1999, and the changes in customer calling patterns
associated with our prepaid phone card program. Management believes
the short-term effects of these factors will not adversely impact the long-term
success and strategy of the Company.


FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1998 AND 1999

     REVENUE

     Revenue for the nine months ended September 30, 1999 was $189.8 million,
representing an increase of 20.5% as compared to the same period in 1998. The
$32.3 million increase in total revenue on a year-to-date basis is attributable
to increases in integrated retail voice services revenue of $19.1 million,
wholesale long distance services revenue of $5.9 million and data services
revenue of $7.3 million. The increase in integrated retail voice services
consists of an increase in local services of $20.4 million partially offset by
a decrease in retail long distance of $1.4 million from $82.2 million to $80.8
million. This decrease in retail long distance was primarily a result of the
effect of price compression, as demonstrated by the fact that retail long
distance minutes increased by 8.1% during the same period. Local services
revenue growth was driven by the continued success of our bundled product
offerings since introducing local services in the fourth quarter of 1997. A
large portion of the increase in wholesale long distance revenues from 1998 to
1999 is attributable to dramatically increased sales of prepaid calling card
services of $23.5 million on a year-to-date basis. The increase in our data
services revenue resulted primarily from sales of private line and competitive
access services, a portion of which are on our fiber network. As a percentage of
revenue, retail services revenue remained constant at approximately 56%. At the
same time, wholesale services revenue decreased from 36.0% of revenue to 32.9%
of revenue and data services increased from 7.8% to 10.3% of revenue.

     COST OF SERVICES

     Cost of services represented 66.9% of revenue for the nine-month period
ended September 30, 1999, as compared to 72.7% for the same period in 1998. The
lower cost of services percentage for the nine-month period ended September 30,
1999 reflects the effects of various improvements in our cost components,
partially offset by changes in our revenue mix. Within wholesale services,
prepaid calling card services revenue has increased while margins have
decreased due to changes in our user calling patterns. Offsetting this increase
in cost of services margin, but also within the wholesale services area, there
has been a significant decrease in international termination services. These
international termination services have lower margin percentages than other
wholesale services. The decreased volume of this international traffic has
resulted in a lower overall cost of services percentages. In addition, we
experienced an increase in the percentage of local services provided through our
facilities, which produce a higher margin than those services provided on a
resale basis.

     Expansion of our fiber optic network, the continuing effect of access
charge reform and rate decreases from our underlying service providers have also
improved our margin percentages. In addition to adding revenues from capacity
sales to other telecommunication providers, our fiber optic network provides for
cost savings throughout the network. However, cost savings from our network were
less than originally anticipated during the nine months ended September 30, 1999
due largely to vendor delays in the delivery of additional network segments.
During the nine months ended September 30, 1999, we deployed 700 route miles of
our fiber optic network, increasing our total fiber route miles to 1,200. We
expect our cost of services as a percentage of revenues to continue to decrease
as we deploy more of our fiber optic network and continue to increase the
percentage of local customers with facilities-based local service.


     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Selling, general and administrative expenses on a year-to-date basis were
$62.2 million, or 32.8% of revenue, in 1999 as compared to $49.3 million, or
31.3% of revenue, in 1998. The increase in selling, general and administrative
expenses was attributable to the significant investments in human resources and
increased marketing and advertising efforts associated with the continued
expansion of our local and data services and deployment of our fiber optic
network. Because these investments often occur in advance of the realization of
significant revenue from local services, they have the effect of increasing
selling, general and administrative expenses as a percentage of revenue. These
investments in infrastructure and support are intended to provide us with the
ability to continue to expand into new markets, maximize customer retention and
provide for growth

     Depreciation and amortization was $14.0 million and $7.7 million in the
nine months ended September 30, 1999 and September 30, 1998, respectively. This
82.1% increase is primarily due to capital expenditures related to the
expansion of


                                       10
<PAGE>

     our network operations centers, fiber optic network and support
infrastructure to accommodate increased traffic volume and expanded service
offerings.


     OTHER INCOME (EXPENSE)

     Interest expense increased from $19.1 million for the nine months ended
September 30, 1998 to $20.4 million for the nine months ending September 30,
1999. The $1.3 million increase is primarily attributable to increased
borrowings under our credit facilities during the first nine months of 1999
compared to 1998. In addition, we capitalized $1.5 million of interest expense
associated with the construction of our network in the nine months ended
September 30, 1999, as compared to $1.1 million for the same period in 1998.

     Interest income decreased from $4.7 million in the nine-month period ended
June 30, 1998 to $2.0 million in the nine months ended September 30, 1999. This
decrease resulted from lower restricted and non-restricted cash balances during
1999.


     EBITDA

     EBITDA for the nine months ended September 30, 1999 was $1.0 million. This
represents an improvement of $7.3 million over the EBITDA loss of $6.3 million
during the same period in 1998. The increase in EBITDA during 1999 was
attributable to the overall revenue and gross margin improvement over the same
period in 1998. These improvements were partially offset by the changes in
customer calling patterns associated with our prepaid phone card program.
Management believes the short-term effects of these calling pattern changes will
not adversely impact the long-term success and strategy of the Company.


INCOME TAXES

     We generated net losses for the three and nine-month periods ended
September 30, 1999 and 1998. Based upon management's plans to expand the
business through the construction and expansion of its networks, customer base
and product offerings, this trend is expected to continue. Given these
circumstances, we have established a valuation allowance of the net deferred
tax assets associated with these net operating losses. As such, there was no
impact on the results from operations for net operating losses generated during
the three and nine-month periods ended September 30, 1999 and 1998. We will
reduce the valuation allowance when, based on the weight of available evidence,
it is more likely than not that some portion or all of the deferred tax assets
will be realized.

     Throughout the period of time that BTI was an S corporation, income,
losses and credits were passed through directly to shareholders and the
shareholders were provided, in the form of dividends, the funds necessary to
meet tax obligations arising from income earned by BTI. We have indemnified
those shareholders for any additional tax obligations arising from the income
earned by BTI while it was an S corporation. We believe that any such
reimbursements will not have a material effect on our financial condition or
results of operations.


LIQUIDITY AND CAPITAL RESOURCES

     REVIEW OF CASH FLOW ACTIVITY

     During the first nine months of 1999 we used $18.8 million of cash to fund
operating activities as compared to $18.7 million during the first nine months
of 1998. Non-cash expenses such as depreciation and amortization partially
offset net losses for the nine-month periods ending September 30, 1998 and 1999
of $28.4 million and $31.8 million, respectively. The $0.1 million increase in
cash used in operations primarily consisted of net changes in accounts and
notes receivable, accounts payable, and other accruals and deferrals from the
nine-month period ending September 30, 1998 to the nine-month period ending
September 30, 1999.

     Cash used in investing activities during the first nine months of 1998 and
1999 amounted to $27.9 million and $39.9 million, respectively. The primary
investment for both periods was capital expenditures. The increase in net
capital expenditures from $48.4 million in the first nine months of 1998 to
$60.9 million in the first nine months of 1999 primarily resulted from the
deployment of the our fiber optic network and purchases of equipment for the
development of our facilities-based local service business. Cash used in
investing activities also includes the capitalization of line access fees,
which represent installation charges paid primarily to the incumbent local
exchange carriers ("ILECs") for securing additional leased fiber optic
facilities. In May 1998, the Company satisfied stock and option repurchase
obligations to a former employee. These obligations arose as a result of the
assumption of stock repurchase obligations in connection with the September
1997 acquisition of the fiber optic assets of FiberSouth and under the 1994
Stock Plan. In settlement of these obligations, the


                                       11
<PAGE>

Company made a $2.3 million cash payment to the former employee. This
transaction is reflected as an adjustment to equity and represents a
reallocation of the original FiberSouth purchase price. Cash used for
investments was offset in part by the provision of $25.0 million and $24.2
million of cash from the restricted cash accounts for the nine-month periods
ending September 30, 1998 and 1999, respectively. This results from our use
of restricted cash to fund interest obligations on the Senior Notes in
March and September of 1998 and 1999. The restricted cash balance as of
September 30, 1999 includes proceeds from the Senior Note offering placed in
escrow to secure the next two scheduled interest payments.

     Cash used in financing activities was $1.6 million for the first nine
months of 1998 due primarily to payments made on the shareholder note payable
and certain capitalized costs associated with financing. During the first nine
months of 1999, financing activities provided us with $47.7 million of cash,
primarily as a result of net borrowings on long-term credit facilities. The
dividends paid during 1999 were to provide funds for tax obligations owed by
BTI's shareholder as a result of net income during the period in which BTI was
an S Corporation for income tax purposes. These reimbursements were in
accordance with the indemnification provisions of the shareholders' agreement
that was terminated in 1997.


     DEBT

     10 1/2% SENIOR NOTES. On September 22, 1997, we issued $250.0 million
principal amount of 10 1/2% Senior Notes (the "Senior Notes") due 2007. Interest
on the Senior Notes is payable semiannually in cash, on each March 15 and
September 15.

     The Senior Notes are unsubordinated indebtedness equal in right of payment
with all of our existing and future unsubordinated indebtedness. Approximately
$74.1 million of the net proceeds from the sale of the Senior Notes was used to
purchase U.S. government securities to secure and fund the balance of the first
six interest payments on the Senior Notes, which are held as restricted cash.
The Senior Notes will mature on September 15, 2007.

     Upon a change in control, as defined in the indenture governing the Senior
Notes, we will be required to make an offer to purchase the Senior Notes at a
purchase price equal to 101% of their principal amount, plus accrued interest.

     The indenture governing the Senior Notes contains certain covenants that
affect, and in certain cases significantly limit or prohibit, among other
things, our ability to incur indebtedness, pay dividends, prepay subordinated
indebtedness, repurchase capital stock, make investments, engage in
transactions with stockholders and affiliates, create liens, sell assets and
engage in mergers and consolidations. If we fail to comply with these
covenants, our obligation to repay the Senior Notes may be accelerated.
However, these limitations are subject to a number of important qualifications
and exceptions. In particular, while the indenture restricts our ability to
incur additional indebtedness by requiring compliance with specified leverage
ratios, notwithstanding these restrictions, it permits us to incur an unlimited
amount of additional indebtedness to finance the acquisition of equipment,
inventory and network assets and up to $100.0 million of additional
indebtedness for general corporate purposes.

     GE CAPITAL CREDIT FACILITIES. Our wholly owned subsidiary, BTI, has a
credit agreement with GE Capital (the "GE Capital Facilities") providing for
the following facilities:

     o A $30.0 million revolving credit facility; and
     o A $30.0 million note facility.

     We amended these facilities effective June 30, 1998 to provide us with
additional operating flexibility. Borrowings under the GE Capital Facilities
are based on a percentage of eligible accounts receivable in the case of the
revolving facility and eligible capital expenditures in the case of the note
facility. The proceeds from both GE Capital Facilities can be used for working
capital, capital expenditures and for general corporate purposes. At September
30, 1999, we had an aggregate of $28.1 million outstanding under these
facilities, in addition to $0.1 million in letters of credit. The GE Capital
Facilities mature on September 22, 2002.

     Amounts drawn under the GE Capital Facilities bear interest, at our
option, at either a floating rate equal to prime or at 30-, 60- or 90-day LIBOR
rates, as we choose, plus, in each case, a percentage rate that fluctuates,
based on the ratio of our total debt to EBITDA, from 0.0% to 1.25% for
borrowings at prime and from 1.75% to 3.0% for borrowings at LIBOR. We are also
required to pay a fee of 0.375% per year on the unused portion of the GE
Capital Facilities.

     BTI's obligations under the GE Capital Facilities are guaranteed by BTITC
and are secured by a first-priority lien on all current and future assets of
BTI and our other subsidiaries, excluding the fiber optic network and related
equipment, and our pledge of the stock of BTI and any intercompany notes.


                                       12
<PAGE>

     Under the GE Capital Facilities, we have agreed, among other things, to
achieve minimum EBITDA targets, meet minimum interest coverage ratios and not
exceed the limits set for capital expenditures in the credit agreement. We have
agreed to, among other things, limits on our ability to incur debt, create
liens, pay dividends, make distributions or stock repurchases, engage in
transactions with affiliates, sell assets and engage in merger and acquisitions,
except as specifically permitted under the credit agreement. The Bank of America
Facility also includes a covenant whereby the Company is required to raise
additional equity financing of $135 million by March 31, 2000. In addition,
these facilities contain affirmative covenants, including, among others,
covenants requiring maintenance of corporate existence, licenses and insurance,
payments of taxes and the delivery of financial and other information. We are
currently in compliance with these covenants, as amended. However, we might not
be able to continue meeting these covenants or, if required, obtain additional
financing on acceptable terms. Our failure to do so may have a material adverse
impact on our business and operations.

     BANK OF AMERICA CREDIT FACILITIES. On September 8, 1999, we obtained a
credit facility from Bank of America (the "Bank of America Facility").
Availability under the Bank of America Facility is based on the amount of fiber
optic network purchased from Qwest Communications and purchases of related
equipment from Nortel Networks, Inc. Availability under the Bank of America
Facility is limited to $37.5 million until the Company raises at least $100
million in additional equity financing, at which time the Bank of America
Facility's availability will increase to $60 million. The proceeds from the Bank
of America Facility can be used for working capital and to fund our fiber optic
network and related infrastructure. At September 30, 1999, there was a total of
$26.0 million outstanding under the Bank of America Facility. The Bank of
America Facility matures on September 22, 2002.

     The Bank of America Facility will bear interest, at our option, at either
the 30-, 60- or 90-day LIBOR rate or the prime rate plus an applicable margin.
This margin varies, based on our financial position and additional equity
issuances, from 1.00% to 2.50% for borrowings under the prime rate option and
from 2.00% to 3.50% for borrowings under the LIBOR option.

     BTI's obligations under the Bank of America Facility are guaranteed by
BTITC and are secured by a first security interest in BTI's fiber optic network
and related equipment and a second security interest in substantially all of the
remaining assets of BTI.

     Under the Bank of America Facility, we have agreed, among other things, to
achieve minimum EBITDA targets, meet minimum interest coverage ratios and not
exceed the limits set for capital expenditures in the credit agreement. We have
also agreed to, among other things, limits on our ability to incur debt, create
liens, pay dividends, make distributions or stock repurchases, engage in
transactions with affiliates, sell assets and engage in mergers and
acquisitions, except as specifically permitted under the credit agreement. The
Bank of America Facility also includes a covenant whereby the Company is
required to raise additional equity financing of $135 million by March 31, 2000.
In addition, the Bank of America Facility contains affirmative covenants,
including, among others, covenants requiring maintenance of corporate existence,
licenses and insurance, payments of taxes, and the delivery of financial and
other information. We are currently in compliance with these covenants as
amended. However, we might not be able to continue meeting these covenants or,
if required, obtain additional financing on acceptable terms. Our failure to do
so may have a material adverse impact on our business and operations.


     CAPITAL SPENDING

     The Company is presently exploring opportunities to raise additional equity
through the public or private market. Given our planned issuance of equity
capital, we currently estimate that our aggregate capital expenditures will be
between $110 and $120 million for the 15 month period ended 12/31/99. Presently
we have outstanding commitments of less than $5 million related to the Company's
fiber optic network. We also expect to make substantial capital expenditures
after 2000. Capital expenditures will be primarily for:

   o the purchase and installation of switches, electronics, fiber, co-location
     facilities and other technologies in existing networks and in additional
     networks to be constructed in our service areas;

   o market expansion, including new sales offices;

   o the continued development of our existing operations centers to service
     anticipated increased traffic volumes and increased geographic areas; and

   o expenditures with respect to our management information systems and
     customer support infrastructure.

     The actual amount and timing of our capital requirements may differ
materially from these estimates as a result of, among other things:

   o the cost of the development of our networks in each of our markets;

                                       13
<PAGE>

   o a change in or inaccuracy of our development plans or projections;

   o a change in the schedule or extent of our roll-out plan;

   o the extent of price and service competition for telecommunication services
     in our markets;

   o the demand for our services;

   o regulatory and technological developments, including additional market
     developments and new opportunities, in the telecommunications industry;

   o an inability to borrow under our credit facilities; and

   o the consummation of acquisitions, joint ventures or strategic alliances.

     Although there can be no assurance, we believe that proceeds from
equity issuance, together with cash on hand, borrowings expected to be
available under our credit facilities and cash flow from operations, will be
sufficient to expand our business as currently planned. In the even our plans
change or prove to be inaccurate, these funds might be insufficient. We might
also require additional capital in the future (or sooner than currently
anticipated) for new business activities related to our current and planned
businesses, or if we decide to make additional acquisitions or enter into joint
ventures and strategic alliances.

     Sources of additional capital could include public and private equity
offerings and, subject to compliance with the provisions in the indenture
governing the 10 1/2% Senior Notes and our credit facilities, debt financings.
Additional financing might not be available, or it might not be available on
terms acceptable to us and within the restrictions contained in our existing
financing agreements. Failure to generate or obtain sufficient funds could
result in delay or abandonment of some or all of our development and expansion
plans.


YEAR 2000 ISSUES

     Beginning in 1996, we conducted a thorough review of our information
technology and operating systems and non-information technology systems, as
well as the systems of our major customers, suppliers, and third party network
service providers to ensure that the systems would properly recognize the Year
2000. We also reviewed internally developed software. As a result of this
assessment, we developed a thorough plan to address the Year 2000 issue. A
project manager and significant other programming and operational staff are
dedicated to the plan's implementation. The Year 2000 plan includes the
wide-ranging assessment of the Year 2000 problems that may affect us, the
development of remedies to address the problems discovered in the assessment
phase, testing of the remedies and the preparation of contingency plans.

     We began implementing the plan in 1997. Implementation was completed in
the third quarter of 1999. We have also completed the evaluation, remediation
and testing phases of the Year 2000 plan. All major business-critical systems
were tested and Year 2000 compliant as of September 30, 1999. In that regard,
we have received assurances or written agreements from significant vendors that
their systems are already Year 2000 compliant. These vendors include our major
suppliers of switching equipment, fiber optic electronics, and billing and
customer care systems. We believe that these systems represent our most
critical business systems. All other systems were in compliance as of September
30, 1999. We have completed testing the systems and applications that have been
corrected or reprogrammed.

     As part of the Year 2000 plan, we sought information from our other
significant hardware, software and other equipment vendors, third party network
providers, other material service providers and material customers regarding
their development and implementation of plans to become Year 2000 compliant. To
date these parties have indicated that they are implementing procedures to
ensure that their computer systems will be Year 2000 compliant by December 31,
1999.

     We have developed contingency plans to deal with potential Year 2000
related business interruptions that may occur. These contingency plans are
designed to address the most reasonably likely worst-case scenarios based upon
the responses of vendors, service providers and customers to our requests for
Year 2000 compliance information.

     Through September 30, 1999, we spent approximately $2.0 million on
Year 2000 projects and activities. The estimated total cost for Year 2000
projects and activities is $2.8 million, excluding capital expenditures. Most
of these capital expenditures, which include both equipment and software, will
not only provide for Year 2000 compliance but are also expected to enhance
operations. In most cases, the expenditures for system modifications will be
merely an acceleration of previously planned improvements. Year 2000 project
costs are being funded through operations and existing credit facilities and
are not expected to have a material effect on our financial condition or
results from operations. We believe we have an effective program in place to
resolve the Year 2000 issue in a timely manner. However, it is not possible to
anticipate all


                                       14
<PAGE>

possible future outcomes, especially when third parties are involved. Failure
by us and/or our major vendors, third party network service providers or other
material service providers or customers to adequately address their respective
Year 2000 issues in a timely manner could have a material adverse effect on our
business, results of operations and financial condition.


NEW ACCOUNTING PRONOUNCEMENTS

     In 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities". We expect to adopt SFAS No. 133 effective
January 1, 2000. We do not expect any significant additional disclosure
requirements or other financial statement impacts to result from the adoption
of SFAS No. 133.

     Certain amounts in the September 30, 1998 Financial Statements have been
reclassified to conform to the September 30, 1999 presentation.

       In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position 98-1, "Accounting For the Costs of
Computer Software Developed For or Obtained For Internal-Use", which requires
the capitalization of certain costs incurred in connection with developing or
obtaining software for internal-use. We adopted the provisions of SOP 98-1 in
our financial statements as of January 1, 1999.

     In April 1998, the AICPA issued Statement of Position 98-5, "Reporting the
Costs of Start-Up Activities", which requires that costs related to start-up
activities be expensed as incurred. We adopted the provisions of SOP 98-5 in
our financial statements as of January 1, 1999. Prior to 1999, we expensed
start-up costs and therefore the adoption of SOP 98-5 will have no impact on
our financial statements.


      ITEM 3 -- QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

INTEREST RATE RISK

     The majority of our debt, which consists of $250.0 million of the 10 1/2%
Senior Notes, bears interest at a fixed rate. Although the actual service
requirements of this debt are fixed, changes in interest rates generally could
put us in a position of paying interest that differs from then existing market
rates. The remainder of our debt consists of the GE Capital Facilities and the
Bank of America Facility, which bear interest at variable rates based upon
market conditions and our financial position. As of September 30, 1999,
borrowings under these facilities totaled $54.1 million. We have not engaged in
any hedging transactions related to these facilities. As market conditions and
outstanding borrowings under these facilities change, we intend to continue to
evaluate the advisability of hedging transactions.

                         PART II -- OTHER INFORMATION

ITEM 1 -- LEGAL PROCEEDINGS

     On September 14, 1998, Gulf Communications, L.L.C. filed suit against us
alleging breach of a telecommunications services agreement for the termination
of long distance traffic. Gulf contends that the agreement requires us to
terminate a specified number of minutes per month and that we did not fulfill
our alleged commitment. Gulf also alleges fraud in the inducement of the
agreement and seeks an unspecified amount of actual and punitive damages, plus
interest, attorneys' fees and costs. We intend to vigorously defend ourselves
against Gulf's claims. Discovery is ongoing. Defending this lawsuit may be
expensive and time-consuming and, regardless of whether the outcome is
favorable to us, could divert substantial financial, management and other
resources from our business. An adverse outcome could subject us to significant
liability.

     Except as described above, we are not a party to any pending legal
proceedings that we believe would, individually or in the aggregate, have a
material adverse effect on our financial condition or results of operations.


ITEM 2 -- CHANGES IN SECURITIES AND USE OF PROCEEDS

     For the three months ended September 30, 1999, we granted options to
purchase an aggregate of 93,988 shares of our common stock to 7 employees and
directors. As a result, for the nine months ended September 30, 1999, we have
granted options to purchase an aggregate of 543,488 shares of our common stock
to 70 employees and directors. The offering of these securities was deemed to
be exempt from registration under Section 4(2) of, or Rule 701 promulgated
under the Securities Act as transactions by an issuer not involving a public
offering.

                           AND RESTATED LOAN AGREEMENT


         THIS FOURTH AMENDMENT TO SECOND AMENDED AND RESTATED LOAN AGREEMENT
(the "Agreement") is made and entered into as of this 8th day of September,
1999, between GENERAL ELECTRIC CAPITAL CORPORATION, a New York corporation
having an office at 3379 Peachtree Road, N.E., Suite 600, Atlanta, Georgia
30326, as lender and agent ("Lender"), and BUSINESS TELECOM, INC., a North
Carolina corporation having an office at 4300 Six Forks Road, Raleigh, North
Carolina 27609 ("Borrower").

                              W I T N E S S E T H:

         WHEREAS, Lender and Borrower are party to that certain Second Amended
and Restated Loan Agreement, dated as of September 22, 1997 (as the same has
been amended by (i) that certain First Amendment to Second Amended and Restated
Loan Agreement, dated May 6, 1998 (ii) that certain Second Amendment to Second
Amended and Restated Loan Agreement, dated June 30, 1998, and (iii) that certain
Third Amendment to Second Amended and Restated Loan Agreement, dated July 15,
1999, as so amended, the "Loan Agreement;" all capitalized terms used herein and
not otherwise expressly defined herein shall have the respective meanings given
to such terms in the Loan Agreement); and

         WHEREAS, Borrower has requested Lender's consent to the transactions
evidenced by that certain Loan Agreement, dated of even date herewith, among
Borrower, Bank of America, National Association, as agent, Bank of America,
National Association, as lender, and the other financial institutions a party
thereto from time to time; and

         WHEREAS, Lender is willing to consent to the transaction described
above, on the condition that Borrower enter this Agreement; and

         WHEREAS, Borrower is willing to enter this Agreement.

         NOW, THEREFORE, in consideration of the foregoing premises, and other
good and valuable consideration, the receipt and legal sufficiency of which is
hereby acknowledged, the parties hereto hereby agree as follows:

                           1. Amendments to the Loan Agreement. The Loan
Agreement is hereby amended as follows:

                  (a) Section 1.1(a) of Article 1 of the Loan Agreement is
         hereby amended by adding the following new definitions thereto in the
         correct alphabetical order:


                           "Acceptable Equity Issuance" shall mean (a) an Equity
                  Issuance or an IPO with respect to which aggregate Proceeds
                  are greater than or equal to $100,000,000; or (b) an IPO and
                  an Equity Issuance with respect to which the combined
                  aggregate Proceeds are greater than or equal to $100,000,000
                  and has


<PAGE>


                  received such Proceeds in a manner acceptable to Agent.

                           "Average Daily Capital Expenditures" shall mean, as
                  of the end of each Fiscal Month and as reflected in the
                  financial statements for such month prepared by Borrower on a
                  basis consistent with its customary accounting practices, an
                  amount equal to (A) all payments and accruals for Capital
                  Expenditures during the then most recently completed six (6)

                      3.29 Year 2000.

                  (a) The Borrower has developed and budgeted for a
                  comprehensive program to address the "Year 2000 problem" (that
                  is, the inability of computers, as well as embedded microchips
                  in non-computing devices, to perform properly date-sensitive
                  functions with respect to certain dates prior to and after
                  December 31, 1999). The Borrower has implemented that program
                  substantially in accordance with its timetable and budget and
                  it has designed such program to substantially avoid the Year
                  2000 problem as to all computers, as well as embedded
                  microchips in non-computing devices, that are material to its
                  business, properties or operations. The Borrower has developed
                  feasible contingency plans that it has designed to ensure
                  uninterrupted and unimpaired business operation in the event
                  of failure of its own or a third party's systems or equipment
                  due to the Year 2000 problem, including those of vendors,
                  customers and suppliers, as well as a general failure of or
                  interruption in its communications and delivery
                  infrastructure.


                  (b) BTITC and the Borrower's Subsidiaries have not developed
                  or budgeted for a program to address the Year 2000 problem and
                  such Person's failure to develop such a program will not
                  result in a Year 2000 problem with such Person's computers, as
                  well as embedded microchips in non-computing devices, that are
                  material to its business properties or operations. In
                  addition, BTITC and the Borrower's Subsidiaries failure to
                  develop a program to address the Year 200 problem will not
                  impair such Person's ability to adequately ensure
                  uninterrupted


<PAGE>

                  and unimpaired business operation in the event of failure of
                  its own or a third party's systems or equipment due to the
                  Year 2000 problem, including those of vendors, customers and
                  suppliers, as well as a general failure of or interruption in
                  its communications and delivery infrastructure.

                  (o) Section 4.1 of Article 4 of the Loan Agreement is hereby
         amended to add the following new subsection (k) thereto:

                           (k) Upon the request of the Agent, a copy of the
                  Borrower's (and BTITC's and Borrower's Subsidiaries', if
                  applicable) plan, timetable and budget to address the Year
                  2000 problem, together with periodic updates thereof and
                  expenses incurred to the date of the request and all
                  contingency plans with respect to the Year 2000 problem
                  (whether such assessment is commissioned by such Person or by
                  a third party (other than Agent or Lenders).

                  (p) Section 5.4 of Article 5 of the Loan Agreement is hereby
         amended by deleting therefrom the reference to the number "$250,000"
         and inserting in lieu thereof the number "$1,000,000."

         hereby amended by adding the phrase "Subject to the terms of the
         Intercreditor Agreement," to the beginning thereof.

         word "thereunder."

                  (s) Section 5.5(b) of Article 5 of the Loan Agreement is
         hereby further amended by adding the phrase "only to the extent such
         actions relate to the GE Capital Primary Collateral" to the last line
         thereof following the word "insurance."

                  (t) Section 5.5(f) of Article 5 of the Loan Agreement is
         hereby amended by adding the phrase "Subject to the terms and
         conditions of the Intercreditor Agreement," to the beginning thereof.

                  (u) Section 5.11 of Article 5 of the Loan Agreement is hereby
         amended by adding the following sentence to the end thereof: "Upon
         formation of such Subsidiary Borrower shall provide Agent with (a) a
         guaranty, in form and substance satisfactory to Agent, pursuant to
         which such Subsidiary guarantees to Agent, for the benefit of Lenders,
         payment of the Obligations, and (b) a pledge agreement, executed by
         Borrower, in form and substance satisfactory to Agent, pursuant to
         which, among other things, (i) the Borrower pledges to Agent, for the
         benefit of Lenders, all of the Stock of such Subsidiary held by
         Borrower at such time and (ii) Borrower agrees to pledge to Agent, for
         the benefit of Lenders, any Stock of such Subsidiary subsequently held
         by Borrower; provided, however, that the priority of Agent's security
         interest in any such Stock shall be subject to the provisions of the
         Intercreditor Agreement."


<PAGE>


                  (v) Article 5 of the Loan Agreement is hereby further amended
         by adding the following new Sections 5.21 and 5.22 thereto:

                  5.21 Revolving Loan and Capex Advance Proceeds. Borrower shall

         Witter Investment Management, Inc.

                  5.22 Year 2000 Compliance. The Borrower shall promptly notify

         customers) that is material to its or any of its Subsidiaries' business
         and operations will not be Year 2000 compliant, except to the extent

pro rata on the basis of their Commitment Percentage. It is understood that no
Lender shall be responsible for any default by any other Lender in its
obligation to make or support Loans hereunder and that each Lender shall be
obligated to make or support the Loans provided to be made or supported by it
hereunder, regardless of the failure of any other Lender to fulfill its
commitments hereunder.

                  (b) Assumption by Agent. Subject to the provisions of Section
10.8 and notwithstanding the occurrence or continuance of a Default or Event of
Default or other failure of any condition to the making of Credit Loans
hereunder, unless Agent shall have received notice from a Lender in accordance
with the provisions of Section 10.8 prior to a proposed borrowing date that such
Lender will not make available to Agent such Lender's ratable portion of the
amount to be borrowed on such date, Agent may assume that such Lender will make
such portion available to Agent in accordance with Section 1.2, and Agent may,
in reliance upon such assumption, make available to Borrower on such date a
corresponding amount. If and to the extent such Lender shall not make such
ratable portion available to Agent, such Lender and Borrower severally agree to
repay to Agent forthwith on demand (provided Borrower shall be entitled to a
five-day grace period) such corresponding amount (the "Make-Whole Amount"),
together with interest thereon for each day from the date such amount is made
available to Borrower until the date such amount is repaid to Agent at the
interest rate selected by Borrower with respect to such Advance or, if lower,
the Maximum Lawful Rate; provided, however, if on the interest payment date next
following the date on which any Lender pays interest to Agent on a Make-Whole
Amount as aforesaid, Borrower defaults in making the interest payment due, then
Agent shall reimburse such Lender for the excess, if any, of the amount of
interest so paid by such Lender on the Make-Whole Amount over the amount of
interest that such Lender would have paid had such Lender been required to pay
interest on the Make-Whole Amount at the Prime Rate Option. If such Lender shall
repay to Agent such corresponding amount, the amount so repaid shall constitute
such Lender's Commitment Percentage of the Loan made on such borrowing date for
purposes of this Agreement. The failure of any Lender to make its Commitment
Percentage of any Loan available shall not (without regard to whether Borrower
shall have returned the amount thereof to Agent in accordance with this Section
1) relieve it or any other Lender of its obligation, if any, hereunder to make
its Commitment Percentage of such Loan available on such borrowing date, but no
Lender shall be responsible for the failure of any other Lender to make its
Commitment Percentage of such Loan available on the borrowing date.

                  (c) Delegation of Authority to Agent.

                       (i) Without limiting the generality of Article 10, each
Lender expressly authorizes Agent to determine on behalf of such Lender the
creation or elimination of any reserves against the Credit Facility. Such
authorization may be withdrawn by the Required Lenders by giving Agent written
notice of such withdrawal signed by the Required Lenders; provided, however,
that unless otherwise agreed by Agent such withdrawal of authorization shall not
become effective until the thirtieth (30th) Business Day after receipt of such
notice by Agent. Thereafter, the Required Lenders shall jointly instruct Agent
in writing regarding such matters with such frequency as the Required Lenders
shall jointly determine.

                       (ii) Unless and until Agent shall have received written
notice from the Required Lenders that because of a Default or Event of Default
the Required Lenders do not intend to make available to Agent such Lenders'
ratable share of Loans made after the effective date of such notice, Agent shall
be entitled to continue to make the assumptions described in Section 1.3(b).
After receipt of the notice described in the preceding sentence, which shall
become effective on the third (3rd) Business Day after receipt of such notice by
Agent unless otherwise agreed by Agent, Agent shall be entitled to make the
assumptions described in Section 1.3(b) as to any Loans as to which it has not
received a written notice to the contrary prior to 11:00 a.m. (Charlotte, North
Carolina time) on the Business Day next preceding the day on which the Loan is
to be made. Agent shall not be required to make any Loan as to which it shall
have received notice by a Lender of such Lender's intention not to make its
ratable portion of such Loan available to Agent. Any withdrawal of authorization
under this Section 1.3(c) shall not affect the validity of any Loans made prior
to the effectiveness thereof.

                  (d) Reduction of Total Commitment.

                       (i) Voluntary Reduction. The Borrower may terminate in
whole, or reduce ratably, any unused portion of the Total Commitment, subject to
Lenders' satisfaction that the Project will be delivered in all material
respects in accordance with the Segment Delivery and Completion Plan; provided,
however, that the Borrower shall give the Agent ten (10) days advance written
notice that such reduction shall be permanent, and that such reduction shall be
in a minimum amount of $1,000,000 and in integral multiples of $1,000,000 in
excess of such amount.

                       (ii) Mandatory Reduction. In the event that there are any
unused portions of the Total Commitment on the Commitment Termination Date, such
unused portion may be cancelled by the Agent, on behalf of the Lenders.

         1.4 Prepayment.

                  (a) Optional Prepayment. Borrower shall have the right at any
time upon sixty (60) days prior written notice to Agent to voluntarily prepay
all or part of the Credit Loan and terminate Borrower's right to receive and
Lenders' obligation to make Advances, without premium or penalty, provided, that
prior to any voluntary prepayment of less than all of the Credit Loan the
Required Lenders shall be reasonably satisfied that the Project will be
delivered in all material respects notwithstanding the economic effect of such
prepayment, such



                                       29
<PAGE>

satisfaction to be evidenced by written notice to the Borrower not later than 45
days after receipt of the notice of prepayment by the Agent. Upon such
prepayment of all of the Credit Loan and such termination, Borrower's right to
receive Advances and Borrower's obligation to pay the Commitment Fee shall
simultaneously terminate. Such prepayment and termination shall be accompanied
by the payment of all accrued and unpaid interest, Fees and expenses thereon.

                  (b) Mandatory Prepayment.

                       (i) [Reserved.]

                       (ii) In the event that the outstanding balance of the
Credit Loan shall at any time exceed the Credit Borrowing Availability, Borrower
shall immediately repay the Credit Loan in the amount of such excess with
interest thereon until such repayment. Any such excess balance shall
nevertheless constitute Obligations that are secured by the Collateral and
entitled to all of the benefits thereof and of the Loan Documents and shall be
evidenced by the Note.

                       (iii) Subject to Section 6.8, if Borrower shall make any
Disposition or Dispositions, (whether occurring in one transaction or a series
of transactions) an amount equal to such Net Cash Proceeds shall be applied to
the payment of any then outstanding Credit Loans.

                       (iv) Subject to Section 6.5, following the occurrence of
an Acceptable Equity Issuance, if Borrower shall issue any Stock (including,
without limitation, any treasury stock of Borrower), an amount equal to such Net
Cash Proceeds shall be applied to the payment of any then outstanding Credit
Loans.

                       (v) On or after September 30, 2001, if Cash Balances
exceed $30,000,000, an amount equal to such excess shall be applied to the
payment of any outstanding Credit Loans; provided, however, that the Borrower
shall not be required to make such prepayment if an Acceptable Equity Issuance
has occurred; and provided, further, that the Borrower shall not be required to
make such prepayment on or after the date that the Credit Loans outstanding are
less than $10,000,000.

       1.5 Repayment of Principal. On the Maturity Date, the Borrower shall
repay to the Agent, for the account of the Lenders, the Credit Loan, together
with all other Obligations of the Borrower due and payable hereunder and under
the Bank of America Fee Letter, in full in immediately available funds. In
addition, the Borrower shall repay to the Agent, for the account of the Lenders,
in immediately available funds, on the dates set forth on Schedule 1.5 hereto
the percentage of the Credit Loan as of the Amortization Commencement Date.

       1.6 [Reserved.]

       1.7 Single Loan. The Credit Loan and all Advances and all of the other
Obligations of Borrower arising under this Agreement and the other Loan
Documents shall constitute one general obligation of Borrower secured, until the
termination date, by all of the Collateral.

                                       30

       1.8 Interest on the Loans.

           (a) Borrower shall be obligated to pay interest to Agent on behalf of
Lenders on the outstanding principal balance of the Loans owing to Lenders from
the Closing Date until the Credit Loan is paid in full either (i) a floating
rate equal to the Prime Rate Option, or (ii) a fixed rate for interest periods
of any LIBOR Option Period equal to its respective LIBOR Option.

           (b) So long as no Default or Event of Default shall have occurred and
be continuing, and subject to the additional conditions set forth in Section
2.2, Borrower shall have the option to (i) request that any Advances be made as
LIBOR Advances, (ii) convert at any time all or any part of outstanding Loans
from Prime Rate Option Advances to LIBOR Advances, (iii) convert any LIBOR
Advance to a Prime Rate Option Advance, subject to payment of LIBOR Breakage
Costs if such conversion is made prior to the expiration of the LIBOR Option
Period applicable thereto, or (iv) continue all or any portion of any Loan as a
LIBOR Advance upon the expiration of the applicable LIBOR Option Period and the
succeeding LIBOR Option Period of that continued Loan shall commence on the last
day of the LIBOR Option Period of the Loan to be continued. Any Loan to be made
or continued as, or converted into, a LIBOR Advance must be a minimum of
$1,000,000 and integral multiples of $1,000,000 in excess of such amount. Any
such election must be made by 10:00 a.m. (Charlotte, N.C. time) on the LIBOR
Determination Date prior to (1) the date of any proposed Advance which is to
bear interest at the LIBOR Option, (2) the end of each LIBOR Option Period with
respect to any LIBOR Advances to be continued as such, or (3) the LIBOR
Determination Date prior to the date on which Borrower wishes to convert any
Prime Rate Option Advances to a LIBOR Advance for a LIBOR Option Period
designated by Borrower in such election. The Borrower shall not have outstanding
LIBOR Advances for more than five (5) different LIBOR Option Periods on any date
of determination. If no election is received with respect to a LIBOR Advance by
10:00 a.m. (Charlotte, N.C. time) on the LIBOR Determination Date prior to the
end of the LIBOR Option Period with respect thereto (or if a Default or an Event
of Default shall have occurred and be continuing of if the additional conditions
precedent set forth in Section 2.2 shall not have been satisfied), that LIBOR
Advance shall be converted to an Prime Rate Option Advance at the end of its
LIBOR Option Period. Borrower must make such election by notice to Agent in
writing, by telecopy or overnight courier. In the case of any conversion or
continuation, such election must be made pursuant to a written notice (a "Notice
of Conversion/Continuation") in the form attached hereto as Exhibit J-1.

           (c) Borrower shall pay interest to Agent on behalf of Lenders (i) in
arrears for the preceding calendar month on the first (1st) day of each calendar
month, commencing on September 1, 1999, (ii) on the Maturity Date, and (iii) if
any interest accrues or remains payable after the Maturity Date, upon demand by
Agent or the Lenders.

           (d) All computations of interest shall be made by Agent or the
Lenders on the basis of a three hundred and sixty (360) day year, in each case
for the actual number of days occurring in the period for which such interest is
payable. The Prime Index Rate shall be determined (i) on the first Business Day
immediately prior to the Closing Date, and (ii) thereafter, on the last Business
Day of each calendar month for calculation of interest for the following month.
Each determination by Agent of an interest rate hereunder shall be conclusive
and binding for all purposes, absent manifest error or bad faith.

                                       31
<PAGE>

           (e) Upon the occurrence of any Default and so long as any Default
shall have occurred and be continuing and at the election of Agent (or upon the
written request of the Required Lenders), the interest rate applicable to the
Obligations (including, without limitation, the Loans), shall be increased by
two percent (2%) per annum above the rate otherwise applicable (the "Default
Rate") until such time as all of the Obligations of Borrower shall have been
paid in full or, if earlier, such time as the Default or Event of Default shall
have been cured or waived in writing by Lenders.

           (f) If any interest or other payment on the Credit Loan becomes due
and payable on a day other than a Business Day, the maturity thereof shall be
extended to the next succeeding Business Day and, with respect to payments of
principal, interest thereon shall be payable at the then applicable rate during
such extension.

           (g) Notwithstanding anything to the contrary set forth in this
Section 1.8, if, at any time until payment in full of all of the Obligations,
the Stated Index Rate for the Loan exceeds the highest rate of interest
permissible under any law which a court of competent jurisdiction shall, in a
final determination, deem applicable hereto (the "Maximum Lawful Rate"), then in
such event and so long as the Maximum Lawful Rate would be so exceeded, the
Stated Index Rate shall be equal to the Maximum Lawful Rate; provided, that if
at any time thereafter the Stated Index Rate is less than the Maximum Lawful
Rate, Borrower shall continue to pay interest hereunder at the Maximum Lawful
Rate until such time as the total interest received by Lenders from the making
of the Loans hereunder is equal to the total interest which Lenders would have
received had the Stated Index Rate been (but for the operation of this
paragraph) the interest rate payable since the Closing Date as otherwise
provided in this Agreement. Thereafter, the Stated Index Rate shall be the rate
of interest provided in Sections 1.8(a) through (f) of this Agreement, unless
and until the rate of interest again exceeds the Maximum Lawful Rate, in which
event this paragraph shall again apply. In no event shall the total interest
received by Lenders pursuant to the terms hereof exceed the amount which Lenders
could lawfully have received had the interest due hereunder been calculated for
the full term hereof at the Maximum Lawful Rate. In the event the Maximum Lawful
Rate is calculated pursuant to this paragraph, such interest shall be calculated
at a daily rate equal to the Maximum Lawful Rate divided by the number of days
in the year in which such calculation is made. In the event that a court of
competent jurisdiction, notwithstanding the provisions of this Section 1.8(g),
shall make a final determination that Lenders have received interest hereunder
or under any of the Loan Documents in excess of the Maximum Lawful Rate, Lenders
shall, to the extent permitted by applicable law, promptly apply such excess
first to any interest due and not yet paid hereunder, then to the outstanding
principal of the Obligations, then to Fees and any other unpaid Obligations and
thereafter shall refund any excess to Borrower or as a court of competent
jurisdiction may otherwise order.

           (h) If after the date of this Agreement the introduction of, or any
change in, any law or any governmental rule, regulation, policy, guideline or
directive (whether or not having the force of law), or any interpretation
thereof, or compliance by Agent or the Lenders therewith,

                  (i) subjects Agent or the Lenders to any tax, duty, charge or
withholding on or from payments due from Borrower (excluding franchise taxes
imposed upon,


                                       32
<PAGE>

and taxation of the overall net income of, the Lenders), or changes the basis of
taxation of payments, due the Lenders hereunder; or

                  (ii) imposes or increases or makes applicable any reserve
requirement or other reserve, assessment, insurance charge, special deposit or
similar requirement against assets of, deposits with or for the account of, or
credit extended by Agent or Lenders; or

                  (iii) imposes any other condition the result of which is to
increase the cost to Agent or Lenders of making, funding or maintaining any
Advances or reduces any amount receivable by Lenders in connection with Advances
or requires Lenders to make payments calculated by reference to the amount of
loans held or interest received by it, by an amount deemed material by the
Lenders; or

                  (iv) imposes or increases any capital requirement or affects
the amount of capital required or expected to be maintained by Lenders or any
corporation controlling Lenders, and Lenders determine that such imposition or
increase in capital requirements or increase in the amount of capital expected
to be maintained is based upon the existence of this Agreement or its Advances
hereunder, all of which may be determined by Lenders' reasonable allocation of
the aggregate of its impositions or increases in capital required or expected to
be maintained, and the result of any of the foregoing is to increase the cost or
reduce the rate of return to Lenders of making, renewing or maintaining the
Loans hereunder, Borrower shall pay to Agent on behalf of the Lenders, and
continue to make periodic payments to Agent, such additional amounts as may be
necessary to compensate Agent and/or the Lenders for such additional cost
incurred or reduced rate of return suffered.


       1.9 Fees.

           (a) Certain Fees to Agent. On the Closing Date, Borrower agrees to
pay to Bank of America, individually, the Fees specified in that certain fee
letter, dated July 16, 1999 among Borrower, BTITC, the Arranger and Bank of
America, as amended from time to time (the "Bank of America Fee Letter").

           (b) Commitment Fee. As additional compensation for Lenders' costs and
risks in making the total amount of the Maximum Credit Loan available to
Borrower, Borrower agrees to pay to Agent for the account of each existing and
non-defaulting Lender, in arrears, on the first (1st) Business Day of each month
with respect to the immediately prior month, from the Closing Date through and
including the Commitment Termination Date, a fee (the "Commitment Fee") for
Borrower's non-use of available funds in an amount equal to 1.50% per annum of
the difference between the respective daily averages of (i) the Credit Borrowing
Availability less an amount equal to the reduction, if any, in the Total
Commitment pursuant to Section 1.3(d)(i) and (ii) the Credit Loan to Borrower
during the period for which the Commitment Fee is due.

       1.10 Receipt of Payments. Borrower shall make each payment under this
Agreement not later than 1:30 p.m. (Charlotte, North Carolina time) on the day
when due in lawful money of the United States of America in immediately
available funds to the Collection Account without setoff, counterclaim or
deduction whatsoever to Agent for the account of the Lenders entitled thereto.
For purposes of computing interest and fees and determining the Credit Borrowing


                                       33
<PAGE>



Availability, all payments (including, without limitation, cash sweeps)
consisting of cash, wire, or electronic transfers in immediately
available/collected funds shall be deemed received by Agent on the Business Day
of such deposit in the Collection Account.

       1.11 Application and Allocation of Payments. Borrower irrevocably waives
the right to direct the application of any and all payments at any time or times
hereafter received from or on behalf of Borrower, and Borrower irrevocably
agrees that Agent shall have the continuing exclusive right to apply any and all
such payments against the then due and payable Obligations of Borrower and in
repayment of Credit Loan as Agent may deem advisable notwithstanding any
previous entry by Agent in the Loan Account or any other books and records. In
the absence of a specific determination by Agent with respect thereto, the same
shall be applied in the following order: (i) then due and payable Fees and
Agent's expenses reimbursable hereunder; (ii) then due and payable interest
payments; and (iii) Obligations other than Fees, expenses and interest. Agent is
authorized to, and at its sole election may, make or cause to be made Advances
on behalf of Borrower for payment of all Fees, expenses, charges, costs,
principal, interest, or other Obligations owing by Borrower under this Agreement
or any of the other Transaction Documents, even if the making of such Advance
causes the outstanding balance of the Credit Loan to exceed the Credit Borrowing
Availability, and Borrower agrees that the making of any such Advance in excess
of the Credit Borrowing Availability shall constitute an automatic Default
entitling Agent to exercise all rights and remedies available to Agent under
this Agreement, the other Transaction Documents, or Applicable Law; provided,
however, that prior to taking any action in connection with such automatic
Default, Agent shall provide Borrower with written notice one day prior to
taking such action.

       1.12 Loan Account and Accounting. Agent shall maintain a loan account
(the "Loan Account") on its books (such Loan Account shall be for accounting
purposes only and shall not be a bank account) to record: (a) all Advances, (b)
all payments made by Borrower, and (c) all other debits and credits as provided
in this Agreement with respect to the Loans or any other Obligations. All
entries in the Loan Account shall be made in accordance with Agent's customary
accounting practices as in effect from time to time. The balance in the Loan
Account, as recorded on Agent's most recent printout or other written statement,
shall be presumptive evidence of the amounts due and owing to Agent and Lenders
by Borrower; provided, that any failure to so record or any error in so
recording shall not limit or otherwise affect Borrower's duty to pay the
Obligations. Agent shall render to Borrower a periodic accounting of
transactions with respect to the Loans setting forth the balance of the Loan
Account. Unless Borrower notifies Agent in writing of any objection to any such
account (specifically describing the basis for such objection), within ninety
(90) days after the date thereof, each and every such accounting shall (absent
manifest error) be deemed final, binding and conclusive upon Borrower in all
respects as to all matters reflected therein unless Borrower, within ninety (90)
days after the date any such accounting is rendered, shall notify Agent in
writing of any objection which Borrower may have to any such accounting,
describing the basis for such objection with specificity. In that event, only
those items expressly objected to in such notice shall be deemed to be disputed
by Borrower. Agent's determination, based upon the facts available, of any item
objected to by Borrower in such notice shall (absent manifest error) be final,
binding and conclusive on Borrower, unless Borrower shall, at Borrower's
expense, request Agent's independent auditor to resolve such objection within
thirty (30) days following Agent's



                                       34
<PAGE>

notification to Borrower of such determination, in which event the resolution
by Agent's independent auditor shall be final, conclusive and binding.

       1.13 Indemnity.

           (a) Borrower shall indemnify and hold Agent, each Lender and the
Affiliates, officers, directors, employees, attorneys and agents of Agent and
each Lender (each, an "Indemnified Person"), harmless from and against any and
all suits, actions, costs, fines, deficiencies, penalties, proceedings, claims,
damages, losses, liabilities and expenses (including, but not limited to,
reasonable attorneys' fees and disbursements and other costs of investigations
or defense, including those incurred upon any appeal) (each, a "Claim") which
may be instituted or asserted against or incurred by such Indemnified Person as
the result of credit having been extended under this Agreement and the other
Transaction Documents or in connection with or arising out of the transactions
contemplated hereunder and thereunder, including, without limitation, any and
all Environmental Liabilities and Costs; provided, that Borrower shall not be
liable for any indemnification to such Indemnified Person to the extent that any
such Claim results from such Indemnified Person's gross negligence or willful
misconduct. NONE OF AGENT, ANY LENDER OR ANY OTHER INDEMNIFIED PERSON SHALL BE
RESPONSIBLE OR LIABLE TO ANY OTHER PARTY HERETO, ANY SUCCESSOR, ASSIGNEE OR
THIRD PARTY BENEFICIARY OF SUCH PERSON OR ANY OTHER PERSON ASSERTING CLAIMS
DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE, EXEMPLARY OR
CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN
EXTENDED UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS OR AS A RESULT OF ANY
OTHER TRANSACTION CONTEMPLATED HEREUNDER OR THEREUNDER.

           (b) In any suit, proceeding or action brought by Agent or any Lender
relating to any Account, Chattel Paper, Contract, Equipment, General Intangible,
Instrument or Document or any other Collateral for any sum owing thereunder, or
to enforce any provision of any Account, Chattel Paper, Contract, General
Intangible, Instrument, or Document, Borrower shall save, indemnify and keep
Agent or such Lender harmless from and against all expense, loss or damage
suffered by reason of any defense, setoff, counterclaim, recoupment or reduction
of liability whatsoever of the obligor thereunder arising out of a breach by
Borrower of any obligation thereunder or arising out of any other agreement,
indebtedness or liability at any time owing to, or in favor of, such obligor or
its successors from Borrower, all such obligations of Borrower shall be and
remain enforceable against, and only against, Borrower and shall not be
enforceable against Agent or any Lender.

           (c) Borrower hereby acknowledges and agrees that neither Agent nor
any Lender (i) is now, or has ever been, in control of any of the Subject
Property or the affairs of Borrower or any Subsidiary of Borrower, and (ii) has
the capacity through the provisions of the Transaction Documents to influence
Borrower's or any such Subsidiary's conduct with respect to the ownership,
operation or management of any of the Subject Property.

           (d) Borrower, for itself and on behalf of its successors and assigns,
hereby waives, releases and forever discharges any now existing or hereafter
created or arising right or claim against Agent and each Lender and their
assigns for contribution, reimbursement,


                                       35
<PAGE>


indemnity or other similar rights against Agent or any Lender or their
respective assigns in any way related to the use, storage, disposal, treatment
or presence of any Hazardous Materials on, in or about the Subject Property,
including any right to contribution that may exist in Borrower's favor pursuant
to the Comprehensive Environmental Response, Compensation, and Liability Act, 42
U.S.C. Section 9601 et seq., or any other similar law, statute or regulation
under any applicable Federal or State law, or under any common law theory.

           (e) To induce Lenders to provide the LIBOR Option on the terms
provided herein, if (i) any LIBOR Advances are repaid in whole or in part prior
to the last day of any applicable LIBOR Option Period (whether that repayment is
made pursuant to any provision of this Agreement or any other Transaction
Document or is the result of acceleration, by operation of law or otherwise);
(ii) Borrower shall default in payment when due of the principal amount of or
interest on any LIBOR Advances; (iii) Borrower shall default in making any
borrowing of, conversion into or continuation of LIBOR Advances after Borrower
has given notice requesting the same in accordance herewith; or (iv) Borrower
shall fail to make any prepayment of a LIBOR Advance after Borrower has given
notice thereof in accordance herewith, Borrower shall indemnify and hold
harmless each Lender from and against all losses, costs and expenses resulting
from or arising from any of the foregoing. Such indemnification shall include
any loss (including loss of margin) or expense arising from such reemployment of
funds obtained by it or from fees payable to terminate deposits from which such
funds were obtained. For the purpose of calculating amounts payable to a Lender
under this Subsection, each Lender shall be deemed to have actually funded its
relevant LIBOR Advances through the purchase of a deposit bearing interest at
the LIBOR Option in an amount equal to the amount of that LIBOR Advance and
having a maturing comparable to the relevant Interest Period; provided, however,
that each Lender may fund each of its LIBOR Advances in any manner it sees fit,
and the foregoing assumption shall be utilized only for the calculation of
amounts payable under this subsection. This covenant shall survive the
termination of this Agreement and the payment of the Notes and all other amounts
payable hereunder. As promptly as practicable under the circumstances, each
Lender shall provide Borrower with its written calculation of all amounts
payable pursuant to this Section 1.13(e) and such calculation shall be binding
on the parties hereto unless Borrower shall object in writing within twenty (20)
Business Days of receipt thereof, specifying the basis for such objection in
detail.

           (f) The indemnification in this Section 1.13 shall survive
termination of this Agreement and the other Transaction Documents executed in
connection herewith as well as payment of the Notes.

       1.14 Access Borrower shall, and shall cause each of its Subsidiaries to:
(i) provide access during normal business hours to Agent and any of its
officers, employees and agents, as frequently as Agent determines to be
appropriate, upon advance notice (unless a Default shall have occurred and be
continuing, in which event no notice shall be required and Agent shall have
access at any and all times), to the properties and facilities of Borrower or
any of its Subsidiaries; (ii) permit Agent and any of its officers, employees
and agents to inspect, audit and make extracts from all of Borrower's records,
files and books of account including, without limitation, management letters
prepared by independent accountants; and (iii) permit Agent to inspect, review,
evaluate and verify, from time to time, at Agent's discretion, the amount,
quantity, value or condition of, or any other matter relating to, the Collateral
and the records thereof of Borrower


                                       36
<PAGE>


and its Subsidiaries at Borrower's or any Subsidiary's locations and at premises
not owned by or leased to Borrower or such Subsidiary, and Borrower agrees to
render to Agent, at Borrower's cost and expense, such clerical and other
assistance as may be reasonably requested with regard thereto. Borrower shall,
and shall cause each of its Subsidiaries to, make available to Agent and its
counsel, as quickly as practicable under the circumstances, originals or copies
of all books, records, board minutes, contracts, insurance policies,
environmental audits, business plans, files, financial statements (actual and
pro forma), filings with Federal, state and local regulatory agencies, and other
instruments and documents which Agent may reasonably request. Agent shall have
the right to discuss Borrower and its Subsidiaries' business, assets,
liabilities, financial condition, results of operations and business prospects
insofar as the same are reasonably related to the rights of Agent hereunder and
under any of the other Transaction Documents, with Borrower and its
Subsidiaries. Borrower shall deliver any document or instrument reasonably
necessary for Agent, as it may from time to time request, to obtain records from
any service bureau or other Person which maintains records for Borrower, and
shall maintain duplicate records or supporting documentation on media,
including, without limitation, computer tapes and discs owned by Borrower.
Borrower shall instruct its certified public accountants and its banking and
other financial institutions to make available to Agent such information and
records as Agent may reasonably request.

       1.15 Taxes.

connection with the Loans or under the Note or any other Transaction Document,
shall be made, in accordance with this Section 1.15, free and clear of and
without deduction for any and all present or future Taxes. If Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under the Note, or any other Transaction Document to Agent for the
account of Lenders, (i) the sum payable shall be increased as may be necessary
so that after making all required deductions (including deductions applicable to
additional sums payable under this Section 1.15) Lenders receive an amount equal
to the sum they would have received had no such deductions been made, (ii)
Borrower shall make such deductions, and (iii) Borrower shall pay the full
amount deducted to the relevant taxing or other authority in accordance with
applicable law.

           (b) Borrower shall indemnify and pay Agent for the account of the
Lenders, within ten (10) days of demand therefor, for the full amount of Taxes
(including, without limitation, any Taxes imposed by any jurisdiction on amounts
payable under this Section 1.15 paid by Agent or any Lender and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto, whether or not such Taxes were correctly or legally asserted; provided,
however, that Agent and any such Lender shall reasonably cooperate with Borrower
in connection with the contesting by Borrower of such amounts.

           (c) Within thirty (30) days of Agent's reasonable request therefor,
Borrower shall furnish to Agent, at its address referred to in Section 11.8, the
original or a certified copy of a receipt evidencing payment thereof of any
material Taxes.

           (d) Each Lender organized under the laws of a jurisdiction outside
the United States (a "Foreign Lender") as to which payments to be made under
this Agreement or under the

                                       37
<PAGE>



Notes are exempt from United States withholding tax under an applicable statute
or tax treaty shall provide to Borrower and Agent a properly completed and
executed Internal Revenue Service Form 4224 or Form 1001 or other applicable
form, certificate or document prescribed by the Internal Revenue Service or the
United States certifying as to such Foreign Lender's entitlement to such
exemption ( a "Certificate of Exemption"). Any foreign Person that seeks to
become a Lender under this Agreement shall provide a Certificate of Exemption to
Borrower and Agent prior to becoming a Lender hereunder. No foreign Person may
become a Lender hereunder if such Person is unable to deliver a Certificate of
Exemption.

1.16     Capital Adequacy; Increased Costs; Illegality.

       (a) If any Lender shall have determined that the adoption after the date
hereof of any law, treaty, governmental (or quasi-governmental) rule,
regulation, guideline or order regarding capital adequacy, reserve requirements
or similar requirements or compliance by any Lender with any request or
directive regarding capital adequacy, reserve requirements or similar
requirements (whether or not having the force of law) from any central bank or
other Governmental Authority increases or would have the effect of increasing
the amount of capital, reserves or other funds required to be maintained by such
Lender and thereby reducing the rate of return on such Lender's capital as a
consequence of its obligations hereunder, then Borrower shall from time to time
upon demand by such Lender (with a copy of such demand to Agent) pay to Agent,
for the account of such Lender, additional amounts sufficient to compensate such
Lender for such reduction. A certificate as to the amount of that reduction and
showing the basis of the computation thereof submitted by such Lender to
Borrower and to Agent shall, absent manifest error, be final, conclusive and
binding for all purposes.

       (b) If, due to either (i) the introduction of or any change in any law or
regulation (or any change in the interpretation thereof) or (ii) the compliance
with any guideline or request from any central bank or other Governmental
Authority (whether or not having the force of law), there shall be any increase
in the cost to any Lender of agreeing to make or making, funding, or maintaining
any Loan, then Borrower shall from time to time, upon demand by such Lender
(with a copy of such demand to Agent), pay to Agent for the account of such
Lender additional amounts sufficient to compensate such Lender for such
increased cost. A certificate as to the amount of such increased cost, submitted
to Borrower and to Agent by such Lender, shall be conclusive and binding on
Borrower for all purposes, absent manifest error. Each Lender agrees that, as
promptly as practicable after it becomes aware of any circumstances referred to
above which would result in any such increased cost, the affected Lender shall,
to the extent not inconsistent with such Lender's internal policies of general
application, use reasonable commercial efforts to minimize costs and expenses
incurred by it and payable to it by Borrowers pursuant to this Section 1.16.

       (c) Notwithstanding anything to the contrary contained herein, if the
introduction of or any change in any law or regulation (or any change in the
interpretation thereof) shall make it unlawful, or any central bank or other
Governmental Authority shall assert that it is unlawful, for any Lender to agree
to make or to make or to continue to fund or maintain any LIBOR Advance, then,
unless that Lender is able to make or to continue to fund or to maintain such
LIBOR Advance at another branch or office of that Lender without, in that
Lender's opinion, adversely affecting it or its Loans or the income obtained
therefrom, on notice thereof and



                                       38
<PAGE>


demand therefor by such Lender to Borrower through Agent, (i) the obligation of
such Lender to agree to make or to make or to continue to fund or maintain LIBOR
Advances shall terminate and (ii) Borrower shall forthwith prepay in full all
outstanding LIBOR Advances owing by Borrower to such Lender, together with
interest accrued thereon, unless Borrower, within five (5) Business Days after
the delivery of such notice and demand, converts all such Loans into a Loan
bearing interest based on the Prime Rate Option.

           (d) Replacement of Lender in Respect of Increased Costs. Within
fifteen (15) days after receipt by Borrower of written notice and demand from
any Lender (an "Affected Lender") for payment of additional amounts or increased
costs as provided in this Section 1.16, Borrower may, at its option, notify
Agent and such Affected Lender of its intention to replace the Affected Lender.
So long as no Default or Event of Default shall have occurred and be continuing,
Borrower, with the consent of Agent, may obtain, at Borrower's expense, a
replacement Lender ("Replacement Lender") for the Affected Lender, which
Replacement Lender must be satisfactory to Agent. If Borrower obtains a
Replacement Lender within ninety (90) days following notice of its intention to
do so, the Affected Lender must sell and assign its Loans and Commitments to
such Replacement Lender for an amount equal to the principal balance of all
Loans held by the Affected Lender and all accrued interest and Fees with respect
thereto through the date of such sale, provided that Borrower shall have
reimbursed such Affected Lender for the additional amounts or increased costs
that it is entitled to receive under this Agreement through the date of such
sale and assignment.

           Notwithstanding the foregoing, Borrower shall not have the right to
obtain a Replacement Lender if the Affected Lender rescinds its demand for
increased costs or additional amounts within fifteen (15) days following its
receipt of Borrower's notice of intention to replace such Affected Lender.
Furthermore, if Borrower gives a notice of intention to replace and does not so
replace such Affected Lender within ninety (90) days thereafter, Borrower's
rights under this Section 1.16 shall terminate and Borrower shall promptly pay
all increased costs or additional amounts demanded by such Affected Lender
pursuant to Sections 1.15(a), 1.16(a) and 1.16(b).

financial statement complies with the description thereof contained in Schedule
3.4. Borrower has prepared and will prepare the projections with care and
diligence, and based upon assumptions which are reasonable, and all of which
assumptions have been disclosed as part of the projections.

       3.5 Material Adverse Change. Neither Borrower, BTITC nor any Subsidiary
of Borrower as of the Closing Date has any obligations, contingent liabilities,
or liabilities for charges, long-term leases or unusual forward or long-term
commitments which are not reflected in the balance sheets of Borrower referred
to in Section 3.4 and which could, alone or in the aggregate, have or result in
a Material Adverse Effect. There has been no material deviation from the
projections regarding Borrower's business dated September 8, 1999 and provided
to Agent. Since December 31, 1998, no event has occurred which would result (nor
is it likely that any event will result) in a Material Adverse Effect.

       3.6 Ownership of Subject Property; Liens.

           (a) Except as described in Schedule 3.6, the real estate listed in
Schedule 3.6 constitutes all of the real property owned by Borrower or any
Subsidiary of Borrower, or leased or used in its business by Borrower and any
Subsidiary of Borrower where the aggregate lease or other usage payments with
respect to such real property equal or exceed $5,000 per month. Borrower and
each Subsidiary of Borrower owns good and marketable fee simple title to all of
its owned real estate, the Collateral and all of its other properties and
assets, and valid and marketable leasehold interests in all of its Leases (both
as lessor and lessee, sublessee or assignee), and none of the real estate, the
Collateral and the other properties and assets of Borrower and such Subsidiary
are subject to any Liens, security interests or other encumbrances except (i)
the Permitted Liens and (ii) from and after the Closing Date, the Lien in favor
of Lenders pursuant to the Security Agreement and the other Collateral
Documents.

           (b) Borrower and each Subsidiary of Borrower has received all deeds,
assignments, waivers, consents, non-disturbance and recognition or similar
agreements, bills of sale and other documents, and has duly effected all
recordings, filings and other actions necessary to establish, protect and
perfect its right, title and interest in and to all such real estate, the
Collateral and other assets or property.

           (c) Except as described in Schedule 3.6: (i) neither Borrower nor any
other party to any such Lease described in Schedule 3.6 is in default of its
obligations thereunder or has


                                       46
<PAGE>


delivered or received any notice of default under any such Lease, and no event
has occurred which, with the giving of notice, the passage of time, or both,
would constitute a default under any such Lease; (ii) neither Borrower nor any
Subsidiary of Borrower owns or holds, or is obligated under or a party to, any
option, right of first refusal or any other contractual right to purchase,
acquire, sell, assign or dispose of any real property owned or leased by such
Person except as set forth therein; and (iii) no portion of any real property
owned or leased by Borrower or any Subsidiary of Borrower has suffered any
material damage by fire or other casualty loss or a release which has not
heretofore been completely repaired and restored to its original condition or is
being remedied. All permits required to have been issued or appropriate to
enable the real property owned or leased by Borrower or any Subsidiary of
Borrower to be lawfully occupied and used for all of the purposed for which they
are currently occupied, and used, have been lawfully issued and are, as of the
date hereof, in full force and effect.

       3.7 Restrictions; No Default. No contract, lease, agreement or other
instrument to which Borrower or any Subsidiary of Borrower is a party or by
which it or any of its properties or assets is bound or affected and no
provision of applicable law or governmental regulation has resulted in a
Material Adverse Effect, or insofar as Borrower can reasonably foresee could
have or will result in a Material Adverse Effect. Neither Borrower nor any
Subsidiary of Borrower is in default, and to Borrower's knowledge no third party
is in default, under or with respect to any contract, agreement, lease or other
instrument to which it is a party and which could have a Material Adverse
Effect, except for the Borrower's failure to make payments under the Nortel
Agreement, which defaults the Borrower will cure within ten (10) days of the
Closing Date. No Default or Event of Default has occurred and is continuing
which could have a Material Adverse Effect.

       3.8 Labor Matters. Except as set forth in Schedule 3.8, there are no
strikes or other labor disputes against Borrower or any Subsidiary of Borrower
that are pending or, to Borrower's knowledge, threatened, which could have or
result in a Material Adverse Effect. Hours worked by and payment made to
employees of Borrower have not been in violation of the Fair Labor Standards Act
or any other applicable law dealing with such matters which would have a
Material Adverse Effect. All payments due from Borrower on account of employee
health and welfare insurance which could have or result in a Material Adverse
Effect if not paid have been paid or accrued as a liability on the books of
Borrower. Except as set forth in Schedule 3.8, neither Borrower nor any
Subsidiary of Borrower has any obligation under any collective bargaining
agreement, management agreement, or any employment agreement, and a copy of each
agreement listed in Schedule 3.8 has been provided to Agent. There is no
organizing activity involving Borrower or any Subsidiary of Borrower pending or
threatened by any labor union or group of employees. Except as set forth in
Schedule 3.14, there are no representation proceedings pending or threatened
with the National Labor Relations Board, and no labor organization or group of
employees of Borrower or any Subsidiary of Borrower has made a pending demand
for recognition, and there are no complaints or charges against such Person
pending or threatened to be filed with any Federal, state, local or foreign
court, governmental agency or arbitrator based on, arising out of, in connection
with, or otherwise relating to the employment or termination of employment by
Borrower or any Subsidiary of Borrower.

       3.9 Ventures, Subsidiaries and Affiliates; Outstanding Stock and
Indebtedness. Except as set forth in Schedule 3.9, Borrower has no Subsidiaries,
is not engaged in any joint venture or partnership with any other Person, and is
not an Affiliate of any other Person. Except as set forth on Schedule 3.9 and
other than Borrower, BTITC will have no Subsidiaries, will be engaged in no
joint venture or partnership with any other Person, and will not be an Affiliate
of any other Person (other than Borrower). The Stock of Borrower, BTITC and each
Subsidiary of Borrower owned by each of the Stockholders named in Schedule 3.9
constitutes all of the issued and outstanding Stock of Borrower, BTITC, and such
Subsidiary. Except as set forth in Schedule 3.9, there are no outstanding rights
to purchase options, warrants or similar rights or agreements pursuant to which
Borrower, BTITC or any Subsidiary of Borrower may be required to issue or sell
any Stock or other equity security. Except as otherwise permitted hereunder, no
dividends, advances or other distributions have been declared, paid or made upon
any Stock of Borrower or BTITC and, except as set forth in Schedule 3.9, since
December 31, 1998, no shares of Stock of Borrower or BTITC have been, or are now
required to be, redeemed, retired, purchased or otherwise acquired for value by
Borrower or BTITC. All outstanding Stock and Indebtedness of Borrower, BTITC and
each Subsidiary of Borrower is described in Schedule 3.9.

       3.10 Government Regulation Neither Borrower nor any Subsidiary of
Borrower (a) is an "investment company" or an "affiliated person" of, or
"promoter" or "principal underwriter" for, an "investment company," as such
terms are defined in the Investment Company Act of 1940 as amended, or (b) is
subject to regulation under the Public Utility Holding Company Act of 1935, the
Federal Power Act, the Interstate Commerce Act or any other Federal or state
statute that restricts or limits such Person's ability to incur Indebtedness,
pledge its assets, or to perform its obligations hereunder, or under any other
Transaction Documents, except to the extent the Federal Communications Act and
comparable state statutes relating to communications prevent the granting of a
security interest in certain General Intangibles. The making of the Loans, and
any Advances in each case by Agent or Lenders, the application of the proceeds
and repayment thereof by Borrower or any Subsidiary of Borrower and the
consummation of the transactions contemplated by this Agreement and the other
Transaction Documents will not violate any provision of any such statute or any
rule, regulation or order issued by the Securities and Exchange Commission.

       3.11 Margin Regulations. Neither Borrower nor any Subsidiary of Borrower
owns any "margin security," as that term is defined in Regulations G and U of
the Board of Governors of the Federal Reserve System (the "Federal Reserve
Board"), and none of the proceeds of the Advances will be used directly or
indirectly, for the purpose of purchasing or carrying any margin security, for
the purpose of reducing or retiring any Indebtedness which was originally
incurred to purchase or carry any margin security or for any other purpose which
might cause any of the Loans or the extensions of credit under this Agreement to
be considered a "purpose credit" within the meaning of Regulation G, T, U or X
of the Federal Reserve Board. Borrower will not take or permit to be taken any
action which might cause this Agreement or any document or instrument delivered
pursuant hereto to violate any regulation of the Federal Reserve Board.

       3.12 Taxes. Except where the failure to do so would not result in a
Material Adverse Effect, all Federal, state, local and foreign tax returns,
reports and statements, including, without limitation, information returns (Form
1120-S) required to be filed by Borrower or any Subsidiary


                                       48
<PAGE>

of Borrower have been filed with the appropriate Governmental Authority and all
Charges and other impositions shown thereon to be due and payable have been paid
prior to the date on which any fine, penalty, interest or late charge may be
added thereto for nonpayment thereof, or any such fine, penalty, interest, late
charge or loss has been paid. Borrower and each Subsidiary of Borrower has paid
when due and payable all Charges required to be paid by it, except where the
failure to pay such Charges to certain local and municipal authorities would not
result in a Material Adverse Effect. Proper and accurate amounts have been
withheld by Borrower and each Subsidiary of Borrower from their respective
employees for all periods in full and complete compliance with the tax, social
security and unemployment withholding provisions of applicable Federal, state,
local and foreign law and such withholdings have been timely paid to the
respective Governmental Agencies. Schedule 3.12 sets forth those taxable years
for which any of the tax returns of Borrower, each Subsidiary of Borrower and
each Stockholder are currently being audited by the IRS or any other applicable
Governmental Authority; and any assessments or threatened assessments in
connection with any such audit or otherwise currently outstanding. Except as
described in Schedule 3.12, neither Borrower nor any Subsidiary of Borrower has
executed or filed with the IRS or any other Governmental Authority any agreement
or other document extending, or having the effect of extending, the period for
assessment or collection of any Charges. Except as set forth in Schedule 3.12,
neither Borrower nor any Subsidiary of Borrower has filed a consent pursuant to
Section 341(f) of the IRC or agreed to have Section 341(f)(2) of the IRC apply
to any dispositions of subsection (f) assets (as such term is defined in Section
341(f)(4) of the IRC). None of the property owned by Borrower or any Subsidiary
of Borrower is property which is required to treat as being owned by any other
Person pursuant to the provisions of Section 168(f)(8) of the Internal Revenue
Code of 1954, as amended and in effect immediately prior to the enactment of the
Tax Reform Act of 1986, or is "tax-exempt use property" within the meaning of
Section 168(h) of the IRC. Neither Borrower nor any Subsidiary of Borrower has
agreed or been requested to make any adjustment under Section 481(a) of the IRC
by reason of a change in accounting method or otherwise. Neither Borrower nor
any Subsidiary of Borrower has any obligation under any written tax sharing
agreement.

       3.13 ERISA.

           (a) Schedule 3.13 lists all Plans maintained or contributed to by
Borrower or any Subsidiary and all Qualified Plans maintained or contributed to
by any ERISA Affiliate, and separately identifies the Title IV Plans,
Multiemployer Plans, any multiple employer plans subject to Section 4064 of
ERISA, unfunded Pension Plans, Welfare Plans and Retiree Welfare Plans. Each
Qualified Plan has been determined by the IRS to qualify under Section 401 of
the IRC, and the trusts created thereunder have been determined to be exempt
from tax under the provisions of Section 501 of the IRC, and to the best
knowledge of Borrower, nothing has occurred which would cause the loss of such
qualification or tax-exempt status. Each Plan is in compliance in all material
respects with the applicable provisions of ERISA and the IRC, including, without
limitation, the filing of reports required under ERISA or the IRC which are true
and correct as of the date filed, and with respect to each Plan, other than a
Qualified Plan, all required contributions and benefits have been paid in
accordance with the provisions of each such Plan. Neither Borrower, any
Subsidiary of Borrower nor other ERISA Affiliate, with respect to any Qualified
Plan, has failed to make any contribution or pay any amount due as required by
Section 412 of the IRC or Section 302 of ERISA or the terms of any such plan.
With



                                       49
<PAGE>

respect to all Retiree Welfare Plans, there are no future anticipated
expenses pursuant to the latest actuarial projections of liabilities, and copies
of such latest projections have been provided to Agent. With respect to Pension
Plans, there are no liabilities for current participants thereunder using PBGC
interest assumptions. Neither Borrower nor any Subsidiary of Borrower has
engaged in a prohibited transaction, as defined in Section 4975 of the IRC or
Section 406 of ERISA, in connection with any Plan which would subject any such
Person (after giving effect to any exemption) to a material Tax on prohibited
transactions imposed by Section 4975 of the IRC or any other material liability.

           (b) Except as set forth in Schedule 3.13: (i) no Title IV Plan has
any Unfunded Pension Liability; (ii) no ERISA Event or event described in
Section 4062(e) of ERISA with respect to any Title IV Plan has occurred or is
reasonably expected to occur; (iii) there are no pending, or to the knowledge of
Borrower, threatened claims, actions or lawsuits (other than claims for benefits
in the normal course), asserted or instituted against (x) any Plan or its
assets, (y) any fiduciary with respect to any Plan, or (z) Borrower or any ERISA
Affiliate with respect to any Plan; (iv) neither Borrower nor any ERISA
Affiliate has incurred or reasonably expects to incur any Withdrawal Liability
(and no event has occurred which, with the giving of notice under Section 4219
of ERISA, would result in such liability) under Section 4201 of ERISA as a
result of a complete or partial withdrawal from a Multiemployer Plan; (v) within
the last five (5) years neither Borrower nor any Subsidiary of Borrower nor
other ERISA Affiliate has engaged in a transaction which resulted in a Title IV
Plan with Unfunded Pension Liabilities being transferred outside of the
"controlled group" (within the meaning of Section 4001(a)(14) of ERISA) of any
such entity; (vi) no plan which is a Retiree Welfare Plan provides for
continuing benefits or coverage for any participant or any beneficiary of a
participant after such participant's termination of employment (except as may be
required by Section 4980B of the IRC and at the sole expense of the participant
or the beneficiary of the participant); (vii) Borrower and each Subsidiary of
Borrower and other ERISA Affiliate have complied with the notice and
continuation coverage requirements of Section 4980B of the IRC and the
regulations thereunder; and (viii) no liability under any Plan has been funded,
nor has such obligation been satisfied with, the purchase of a contract from an
insurance company that is not rated AAA by Standard & Poor's Corporation and the
equivalent by each other nationally recognized rating agency.

       3.14 No Litigation. Except as set forth in Schedule 3.14, no action,
claim or proceeding is now pending or, to the knowledge of Borrower, threatened
against Borrower or any Subsidiary of Borrower, at law, in equity or otherwise,
before any court, board, commission, agency or instrumentality of any Federal,
state, or local government or of any agency or subdivision thereof, or before
any arbitrator or panel of arbitrators which (a) challenges any such Person's
right, power, or competence to enter into or perform any of its obligations
under the Transaction Documents, or the validity or enforceability of any
Transaction Document or any action taken thereunder, (b) if determined
adversely, could have or result in a Material Adverse Effect or (c) that could
have a Material Adverse Effect on the rights or remedies of the Agent or the
Lenders or on the ability of Borrower to perform its obligations hereunder or
under any other Transaction Document. To the knowledge of Borrower, there does
not exist a state of facts which is reasonably likely to give rise to such
proceedings and which could have or result in a Material Adverse Effect.

                                       50
<PAGE>

       3.15 Brokers. Except as set forth in Schedule 3.15, no broker or finder
acting on behalf of Borrower, BTITC or any Subsidiary of Borrower brought about
the obtaining, making or closing of the Loans or any other transactions
contemplated by the Loan Documents, and Borrower has no obligation to any Person
in respect of any finder's or brokerage fees in connection therewith.

       3.16 Patents, Service Marks, Trademarks, Copyrights and Licenses. Except
as otherwise set forth in Schedule 3.16, Borrower and each Subsidiary of
Borrower owns all material licenses, patents, patent applications, copyrights,
service marks, trademarks, trademark applications, and trade names necessary to
continue to conduct its business as heretofore conducted by it, now conducted by
it and proposed to be conducted by it, each of which is listed, together with
United States Patent and Trademark Office application or registration numbers,
where applicable, in Schedule 3.16. Except as set forth in Schedule 3.16,
Borrower and each Subsidiary of Borrower conducts business without infringement
or claim of infringement of any license, patent, copyright, service mark,
trademark, trade name, trade secret or other intellectual property right of
others, except where such infringement or claim of infringement could not have
or result in a Material Adverse Effect. Except as set forth in Schedule 3.16,
there is no infringement or claim of infringement by others of any material
license, patent, copyright, service mark, trademark, trade name, trade secret or
other intellectual property right of Borrower or any Subsidiary of Borrower.

       3.17 Full Disclosure. No information contained in this Agreement, the
other Transaction Documents, the Financials or any written statement furnished
by or on behalf of Borrower, BTITC or any Subsidiary of Borrower pursuant to the
terms of this Agreement, which has previously been delivered to Agent or any
Lender, contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements contained herein or therein not
misleading in light of the circumstances under which they were made.

3.18 Hazardous Materials. Except as set forth in Schedule 3.18, the Subject
Property is free of contamination from any Hazardous Material. In addition,
Schedule 3.18 discloses existing or potential environmental liabilities of
Borrower or any Subsidiary of Borrower of which Borrower has knowledge and which
could constitute or result in a Material Adverse Effect or Environmental
Liabilities and Costs. Neither Borrower nor any Subsidiary of Borrower has
caused or suffered to occur any Release at, under, above or within any real
property which it owns or leases. Neither Borrower nor any Subsidiary of
Borrower is involved in operations which, to the best of such Person's
knowledge, could lead to the imposition of any liability or Lien on it, or on
any owner of any premises which it occupies, under the Environmental Laws, and
neither Borrower nor any Subsidiary of Borrower has, to the best of such
Person's knowledge, permitted any tenant or occupant of such premises to engage
in any such activity.

       3.19 Insurance Policies. Part II of Schedule 3.19 lists all insurance of
any nature maintained for current occurrences by Borrower and each Subsidiary of
Borrower, as well as a summary of the terms of such insurance. The Collateral
and all other property and assets of Borrower are insured in accordance with the
requirements of this Agreement and the Security Agreement.

       3.20 Deposit Accounts. Schedule 3.20 lists all banks and other financial
institutions at which Borrower and each Subsidiary of Borrower maintains
deposits and/or other accounts, and such Schedule correctly identifies the name,
address and telephone number of each such depository, the name in which the
account is held, a description of the purpose of the account, and the complete
account number.

       3.21 Material Agreements. Schedule 3.21 lists all outstanding material
contracts and agreements ("Material Agreements") to which Borrower will be a
party as of the Closing Date, except (a) the leases listed in Schedule 3.6, (b)
contracts entered into in the ordinary course of Borrower's business with any
customer that did not purchase an aggregate of more than $1,000,000 in products
or services in 1998, (c) purchase orders covering inventory ordered in the
ordinary course of business, (d) contracts entered into in the ordinary course
of Borrower's business (other than contracts with vendors or Fiber Use
Agreements), which do not involve an aggregate expenditure in any year of more
than $1,000,000 and which do not have a term exceeding one (1) year, and (e)
written sales commission agreements. Except as set forth in Schedule 3.21, each
Material Agreement is in full force and effect and is binding upon parties
thereto, no such Material Agreement has been amended and there exists no default
under any Material Agreement by any party thereto, except for the Borrower's
failure to make payments under the Nortel Agreement, which defaults the Borrower
will cure within ten (10) days of the Closing Date..

       3.22 Liens.

           (a) No effective security agreement, financing statement, mortgage,
equivalent security or lien instrument or continuation statement covering all or
any part of the Collateral is on file or of record in any jurisdiction in which
such filing or recording would be effective to perfect a Lien on such
Collateral, except (i) those filed by Borrower in favor of Lenders pursuant to
the Security Agreement and the other Collateral Documents, (ii) those relating
to Permitted Liens and (iii) certain Liens described in Paragraph 7 of the
Perfection Certificate pursuant to which the Agent has received a letter,
satisfactory to the Agent, from the related lender stating that UCC-3
termination statements will be filed within thirty (30) days of the Closing Date
and with respect to which such termination statements have been filed to the
satisfaction of Agent in the appropriate jurisdictions within thirty (30) days
of the Closing Date.

           (b) The information set forth in the Perfection Certificate,
substantially in the form of Exhibit F hereto, delivered by Borrower to Agent on
or prior to the Closing Date, is true, correct and complete as of the Closing
Date.

           (c) As a result of the filing of appropriate financing statements in
the jurisdictions listed in Schedule 3.22 hereto, this Agreement and the other
Collateral Documents will be at the Closing Date effective to create a valid and
continuing Lien upon, and with respect to the BofA Collateral, a first priority
perfected security interest in favor of Lenders in the BofA Collateral and with
respect to the Collateral other than the BofA Collateral, a second priority
perfected security interest, in favor of the Lenders in such Collateral with
respect to which a security interest may be perfected by filing, pursuant to the
UCC as adopted in such jurisdiction, except for the Permitted Liens, and is
enforceable as such as against creditors of, and purchasers from, Borrower
(other than purchasers of Inventory in the ordinary course of business). All
action


                                       52

Lien and Security Interest of Agent on behalf of Lenders in each item set forth
in Schedule 3.23 hereto, including, without limitation, the execution and

Agent's security in the Instruments, has been made. None of the Instruments are
subject to any Liens, security interests or other encumbrances except Permitted
Liens and those Liens specifically designated in Schedule 6.7 hereto. Borrower
shall not change the location of its securities accounts or take any other
action which would render inaccurate the foregoing notification to the financial
intermediary regarding Agent's security interest in the Instruments.

merchantable quality, free from any defects; (d) such Inventory is not subject
to any licensing, patent, royalty, trademark, trade name or copyright agreements

property is subject; (f) except as set forth in Paragraph 2(e) of the Perfection
Certificate or as notified in writing to Agent or Lenders, no such Inventory is
stored with a bailee, warehouseman, consignee or similar party; and (g) all

requirements of the Fair Labor Standards Act, as amended.

       3.26 Equipment. With respect to any Equipment scheduled or listed on the

       3.27 [Reserved].

       3.28 [Reserved].

       3.29 Year 2000.

           (a) The Borrower has developed and budgeted for a comprehensive
program to address the "Year 2000 problem" (that is, the inability of computers,
as well as embedded microchips in non-computing devices, to perform properly
date-sensitive functions with respect to certain dates prior to and after
December 31, 1999). The Borrower has implemented that program substantially in
accordance with its timetable and budget and it has designed such program to
substantially avoid the Year 2000 problem as to all computers, as well as
embedded microchips in non-computing devices, that are material to its business,
properties or operations. The Borrower has developed feasible contingency plans
that it has designed to adequately ensure uninterrupted and unimpaired business
operation in the event of failure of its own or a third party's systems or
equipment due to the Year 2000 problem, including those of vendors, customers
and suppliers, as well as a general failure of or interruption in its
communications and delivery infrastructure.

           (b) BTITC and the Borrower's Subsidiaries have not developed or
budgeted for a program to address the Year 2000 problem and such Person's
failure to develop such a program will not result in a Year 2000 problem with
such Person's computers, as well as embedded microchips in non-computing
devices, that are material to its business properties or operations. In
addition, BTITC and the Borrower's Subsidiaries' failure to develop a program to
address the Year 2000 problem will not impair such Person's ability to
adequately ensure uninterrupted and unimpaired business operation in the event
of the failure of its own or a third party's systems or equipment due to the
Year 2000 problem, including those of vendors, customers and suppliers, as well
as a general failure of or interruption in its communications and delivery
infrastructure.

4.FINANCIAL STATEMENTS AND INFORMATION

Borrower irrevocably makes, constitutes and appoints Agent for the benefit of

Borrower's true and lawful agent and attorney-in-fact for the purpose of making,
settling and adjusting claims under the "All Risk" policies of insurance,
endorsing the name of Borrower on any check, draft, instrument or other item of

premium and take any other action with respect thereto which Agent deems
advisable. All sums so disbursed, including, without limitation, attorneys'
fees, court costs and other charges related thereto, shall be payable on demand
by Borrower to Agent and shall be additional Obligations hereunder secured by
the Collateral; provided, that if and to the extent Borrower fails to promptly
pay any of such sums upon Agent's demand therefor, Agent on behalf of Lenders is
authorized to, and at its option may, make or cause to be made Advances on

(ii) applied to the payment of the Obligations.

Borrower to) perform and comply with, within all required time periods, all of
its obligations and enforce all of its rights under each agreement to which it

which it is a party where the failure to so perform and enforce could have or
result in a Material Adverse Effect. Borrower shall not (and shall not permit
any



                                       59

this Agreement), so long as there are Obligations outstanding hereunder, but not
more frequently than every three (3) months, Borrower will supplement (or cause
to be supplemented) each Schedule hereto, or representation herein or to or in
any other Transaction Document with respect to any matter hereafter arising
which, if existing or occurring at the date of this Agreement, would have been
required to be set forth or described in such Schedule or as an exception to
such representation or which is necessary to correct any information in such
Schedule or representation which has been rendered inaccurate thereby; provided,
that such supplement to such Schedule or representation shall not be deemed an
amendment thereof unless expressly consented to in writing by Agent, and no such
amendments, except as the same may be consented to in a writing which expressly
includes a waiver, shall be or be deemed a waiver by Lenders of any Default or
Event of Default disclosed therein.

       5.9 Environmental Matters. Borrower shall (and shall cause each

financial statements distributed to any creditors of BTITC shall, to the extent
permitted by GAAP, clearly establish the corporate separateness of BTITC from
Borrower and each of BTITC's other Subsidiaries (if any). Finally, neither
Borrower nor any Subsidiary of Borrower shall take any action, or conduct its
affairs in a manner, which is likely to result in the separate corporate
existence of BTITC from that of any or all of Borrower or any Subsidiary of
Borrower being ignored, or in the assets and liabilities of Borrower or any
Subsidiary of Borrower being substantively consolidated with those of BTITC in a
bankruptcy, reorganization or other insolvency proceedings.

law, neither this Agreement nor its contents will be disclosed publicly or
privately except to those individuals who are Borrower's officers, employees or
advisors who have a need to know of them as a result of their being or expecting
to be specifically involved in the proposed transaction and then only on the
condition that each such person or entity agree to be bound by the provisions of
this Section 5.20. Without limiting the generality of the foregoing, none of
such persons shall, except as required by law, use or refer to Agent or Lenders,
or any of their affiliates, in any disclosure made in connection with the
transactions contemplated hereby without prior written consent of Agent or
Lenders, respectively, and provided further that any such requested consent of

into and maintaining in full force and effect until the Termination Date one or
more Interest Rate Protection Agreements with a bank or other financial
institution having capital, surplus and undivided profits of at least
$500,000,000 satisfactory to the Agent and which agrees in writing to be bound
by the Intercreditor Agreement (an "Eligible Counterparty"); provided that if an
Interest Rate Protection Agreement is with an Eligible Counterparty other than a
Lender, the obligations of Borrower thereunder will not be secured by the
Security Documents or any other Lien on the Property of any Lender and will be
subordinated to the Obligations in a manner and pursuant to terms and conditions
which are in all respects satisfactory to the Required Lenders.

       5.22 Use of Proceeds. The Borrower shall use the proceeds of the Loans

       5.24 Amendment of Contracts.

           The Borrower shall not (i) cancel or terminate the Qwest Agreement or
Nortel Agreement; (ii) sell, assign (other than pursuant to the Security

Subsidiary to conduct all transactions otherwise permitted under this Agreement
with any of its Subsidiaries, Affiliates, BTITC, directors, officers, employees
and shareholders on terms that are fair and reasonable and no less favorable to
the Borrower or any such Subsidiary than it would obtain in a comparable
arm's-length transaction with a Person not so related to Borrower.

       5.26 Maintenance of Pari Passu Status. The Borrower shall take all
actions necessary to ensure that the payment Obligations of the Borrower under
this Agreement and the other Transaction Documents shall at all times rank at

       5.27 Year 2000 Compliance The Borrower shall promptly notify the Agent in
the event that the Borrower discovers or determines that any computer
application (including those of its suppliers, vendors and customers) that is

causes (or permits any holder of such Indebtedness or a trustee to cause) such
Indebtedness, or a portion thereof in an aggregate amount exceeding $1,000,000

dates of payment, or (iii) causes any of the Subordinated Indebtedness to become

       8.2 Remedies. Subject to the terms and conditions of the Intercreditor
Agreement:

           (a) If any Default or Event of Default shall have occurred and be
continuing, beyond the expiration of any cure periods applicable thereto, (i)
the rates of interest applicable to the Loans shall automatically increase to
the Default Rate, as provided in Section 1.8(e), (ii) Lenders' obligation to
make further Advances shall terminate, and (iii) Lender may seek the approval of
and by any Governmental Authority whose consent may be necessary or desirable
with respect to the exercise of any remedy under the BTITC Pledge Agreement
(whether with respect to a then current Default or Event of Default or
otherwise).

           (b) In addition, if any Event of Default shall have occurred and be
continuing, beyond the expiration of any cure periods applicable thereto, Agent
may, without notice and at the direction of the Required Lenders in their sole
discretion, take any one or more of the following actions: (i) declare all or
any portion of the Obligations to be forthwith due and payable, whereupon such
Obligations shall become and be due and payable provided, that upon the
occurrence of an Event of Default specified in Sections 8.1(f), (g), (h) or (j),
the Obligations shall become immediately due and payable without declaration,
notice or demand by Agent; or (ii) exercise any of the rights and remedies
provided to Agent or Lenders under the Transaction Documents or at law or
equity, including, without limitation, all rights and remedies provided to a
secured party under the Code. Without limiting the generality of the foregoing,
Borrower expressly agrees that in any such event Agent on behalf of the Lenders,
without demand of performance or other demand, advertisement or notice of any
kind (except the notice specified


                                       70
<PAGE>

below of time and place of public or private sale) to or upon Borrower or any
other Person (all and each of which demands, advertisements and notices are
hereby expressly waived to the maximum extent permitted by the UCC and other
applicable law), may forthwith enter upon the premises of Borrower where any
Collateral is located through self-help, without judicial process, without first
obtaining a final judgment or giving Borrower notice and opportunity for a
hearing on Lenders' claim or action, and without paying rent to Borrower, and
collect, receive, assemble, process, appropriate and realize upon the
Collateral, or any part thereof, and may forthwith sell, lease, assign, give an
option or options to purchase, or sell or otherwise dispose of and deliver said
Collateral (or contract to do so), or any part thereof, in one or more parcels
at public or private sale or sales, at any exchange at such prices as it may
deem best, for cash or on credit or for future delivery without assumption of
any credit risk. Agent shall have the right upon any such public sale or sales
and, to the extent permitted by law, upon any such private sale or sales, to
purchase for the benefit of Lenders the whole or any part of said Collateral so
sold, free of any right or equity of redemption, which equity of redemption
Borrower hereby releases. Such sales may be adjourned and continued from time to
time with or without notice. Agent on behalf of the Lenders shall have the right
to conduct such sales on Borrower's premises or elsewhere and shall have the
right to use Borrower's premises without charge for such sales for such time or
times as Agent deems reasonably necessary or advisable.

           (c) Borrower further agrees, at Agent's request, to assemble the
Collateral and make it available to Agent on behalf of the Lenders at places
which Agent shall reasonably select, whether at Borrower's premises or
elsewhere. Until Agent is able to effect a sale, lease, or other disposition of
Collateral, Agent on behalf of the Lenders shall have the right to use or
operate Collateral or any part thereof to the extent that it deems appropriate
for the purpose of preserving Collateral or its value or for any other purpose
deemed appropriate by Agent. Neither Agent nor any Lender shall have any
obligation to Borrower to maintain or preserve the rights of Borrower as against
third parties with respect to Collateral while Collateral is in the possession
of Agent. Agent may, if it so elects at the direction of the Required Lenders in
their sole discretion, seek the appointment of a receiver or keeper to take
possession of Collateral and to enforce any of Agent's remedies on behalf of the
Lenders with respect to such appointment without prior notice or hearing. Agent
shall apply the net proceeds of any such collection, recovery, receipt,
appropriation, realization or sale, as provided in Section 8.2(f) hereof,
Borrower remaining liable for any deficiency remaining unpaid after such
application, and only after so paying over such net proceeds and after the
payment by Agent of any other amount required by any provision of law,
including, but not limited to, Section 9-504(1)(c) of the UCC (but only after
Agent has received what Agent considers reasonable proof of a subordinate
party's security interest), need Agent account for the surplus, if any, to
Borrower. To the maximum extent permitted by applicable law, Borrower waives all
claims, damages, and demands against Agent and Lenders arising out of the
repossession, retention or sale of Collateral except such as arise out of the
gross negligence or willful misconduct of such party. Borrower agrees that five
(5) days prior notice by Agent or any Lender to Borrower of the time and place
of any public sale or of the time after which a private sale may take place is
reasonable notification of such matters. Borrower shall remain liable for any
deficiency if the proceeds of any sale or disposition of the Collateral are
insufficient to pay all amounts to which Agent and Lenders are entitled,
Borrower also being liable for any attorneys' fees incurred by Agent and Lenders
to collect such deficiency.

                                       71
<PAGE>

           (d) Borrower agrees to pay any and all reasonable costs of Agent and
Lenders, including, without limitation, attorneys' fees in an amount not to
exceed (15%) of the amount then owing by Borrower to Agent and Lenders incurred
in connection with the enforcement of any of its rights and remedies hereunder.

           (e) Except as otherwise specifically provided herein, Borrower hereby
waives presentment, demand, protest or any notice (to the maximum extent
permitted by applicable law) of any kind in connection with this Agreement, any
of the other Transaction Documents or any Collateral.

           (f) The Proceeds (which Proceeds shall be determined in accordance
with the Intercreditor Agreement) of any sale, disposition or other realization
upon all or any part of the Collateral shall be distributed by Agent upon
receipt, in the following order of priorities:

                           first, to Agent in an amount sufficient to pay in
         full the reasonable expenses of Agent in connection with such sale,
         disposition or other realization, including, but not limited to, all
         expenses, liabilities and advances incurred or made by Agent in
         connection therewith, including, but not limited to, attorney's fees in
         an amount not to exceed 15% of the aggregate amount then owing by
         Borrower to Agent and Lenders;

                           second, to the Agent for the benefit of Lenders in an
         amount equal to the then due and unpaid accrued interest, fees and
         prepayment fees, if any, on the Obligations;

                           third, to the Agent for the benefit of Lenders in an
         amount equal to any other Obligations or amounts owed, if any, in
         connection with the Obligations;

                           fourth,  to the  Agent  for the  benefit  of  Lenders
         in an  amount  equal to any  Obligations which are then unpaid;

                           fifth, as otherwise required by the Intercreditor
         Agreement; and

                           finally, upon payment in full of all of the
         Obligations, to Borrower or its representatives or to whomsoever may be
         lawfully entitled to receive the same, or as a court of competent
         jurisdiction may direct.

       8.3 Waivers by Borrower. Except as otherwise provided for in this
Agreement and applicable law to the full extent permitted by applicable law,
subject to the terms and conditions of the Intercreditor Agreement, Borrower
waives: (a) presentment, demand and protest, and notice of presentment,
dishonor, intent to accelerate, acceleration, protest, default, nonpayment,
maturity, release, compromise, settlement, extension or renewal of any or all
Transaction Documents, notes, commercial paper, accounts, contract rights,
documents, instruments, chattel paper and guaranties at any time held by Agent
or any Lender on which Borrower may in any way be liable, and hereby ratifies
and confirms whatever Agent or Lenders may do in this regard; (b) all rights to
notice and a hearing prior to Agent's taking possession or control of, or to
Agent's replevy, attachment or levy upon, the Collateral or any bond or security
which might be required by any court prior to allowing Agent to exercise any of
its remedies; and (c) the benefit


                                       72
<PAGE>


of all valuation, appraisal and exemption laws. Borrower acknowledges that it
has been advised by counsel of its choice with respect to this Agreement, the
other Transaction Documents and the transactions evidenced hereby and thereby.

9. SUCCESSORS AND ASSIGNS

       This Agreement and the other Transaction Documents shall be binding on
and shall inure to the benefit of Borrower, Agent, Lenders, and their respective
successors and assigns, except as otherwise provided herein or therein. Borrower
may not assign, transfer, hypothecate or otherwise convey its rights, benefits,
obligations or duties hereunder or under any of the other Transaction Documents
without the prior express written consent of Lenders. Any such purported
assignment, transfer, hypothecation or other conveyance by Borrower without the
prior express written consent of Lenders shall be void. The terms and provisions
of this Agreement and the other Transaction Documents are for the purpose of
defining the relative rights and obligations of Borrower, Agent and Lenders with
respect to the transactions contemplated hereby and, except as expressly set
forth in Section 1.13 hereof, there shall be no third party beneficiaries of any
of the terms and provisions of this Agreement or any of the other Transaction
Documents.

10. ASSIGNMENT AND PARTICIPATIONS; AGENT

       10.1 Assignment and Participations.

           (a) Borrower consents to any Lender's assignment of, and/or sale of
participations in, at any time or times, the Transaction Documents, Loans, and
any Commitment or of any portion thereof or interest therein, including any
Lender's rights, title, interests, remedies, powers or duties thereunder,
whether evidenced by a writing or not, including, without limitation, any
assignment pursuant to the terms and conditions of the Intercreditor Agreement.
Any assignment by a Lender shall (i) require the consent of Agent (which shall
not be unreasonably withheld or delayed) and the execution of an assignment
agreement (an "Assignment Agreement") substantially in the form attached hereto
as Exhibit M and otherwise in form and substance satisfactory to, and
acknowledged by, Agent; (ii) be conditioned on such assignee Lender representing
to the assigning Lender and Agent that it is purchasing the applicable Loans to
be assigned to it for its own account, for investment purposes and not with a
view to the distribution thereof; (iii) if a partial assignment, be in an amount
at least equal to $5,000,000 and, after giving effect to any such partial
assignment, the assigning Lender shall have retained Commitments in an amount at
least equal to $5,000,000; (iv) include a payment to Agent of an assignment fee
of $3,500; (v) be conditioned upon such Lender executing as written joinder to
the Intercreditor Agreement, in form and substance satisfactory to the Agent and
GECC as agent under the GECC Loan Agreement. In the case of an assignment by a
Lender under this Section 10.1, the assignee shall have, to the extent of such
assignment, the same rights, benefits and obligations as it would if it were a
Lender hereunder. The assigning Lender shall be relieved of its obligations
hereunder with respect to its Commitments or assigned portion thereof from and
after the date of such assignment. Borrower hereby acknowledges and agrees that
any assignment will give rise to a direct obligation of Borrower to the assignee
and that the assignee shall be considered to be a "Lender." In all instances,
each Lender's liability to make Loans hereunder shall be several and not joint
and shall be limited to such Lender's Commitment


                                       73
<PAGE>

Percentage. In the event Agent or any Lender assigns or otherwise
transfers all or any part of a Note, Agent or any such Lender shall so notify
Borrower and Borrower shall, upon the request of Agent or such Lender, execute
new Notes in exchange for the Notes being assigned. Notwithstanding the
foregoing provisions of this Section 10.1(a), any Lender may at any time pledge
or assign all or any portion of such Lender's rights under this Agreement and
the other Transaction Documents to a Federal Reserve Bank; provided, however,
that no such pledge or assignment shall release such Lender from such Lender's
obligations hereunder or under any other Transaction Document.

           (b) Any participation by a Lender of all or any part of its
Commitments shall be in an amount at least equal to $5,000,000, and with the
understanding that all amounts payable by Borrowers hereunder shall be
determined as if that Lender had not sold such participation, and that the
holder of any such participation shall not be entitled to require such Lender to
take or omit to take any action hereunder except actions directly affecting (i)
any reduction in the principal amount of, or interest rate or Fees payable with
respect to, any Loan in which such holder participates, (ii) any extension of
the final maturity date of any Loan in which such holder participates, and (iii)
any release of all or substantially all of the Collateral (other than in
accordance with the terms of this Agreement, the Collateral Documents or the
other Transaction Documents). Solely for purposes of Sections 1.13, 1.15, 1.16
and 10.7, Borrower acknowledges and agrees that a participation shall give rise
to a direct obligation of Borrowers to the participant and the participant shall
be considered to be a "Lender." Except as set forth in the preceding sentence
Borrower shall not have any obligation or duty to any participant. Neither Agent
nor any Lender (other than the Lender selling a participation) shall have any
duty to any participant and may continue to deal solely with the Lender selling
a participation as if no such sale had occurred.

           (c) Except as expressly provided in this Section 10.1, no Lender
shall, as between Borrower and that Lender, or Agent and that Lender, be
relieved of any of its obligations hereunder as a result of any sale,
assignment, transfer or negotiation of, or granting of participation in, all or
any part of the Loans, the Notes or other Obligations owed to such Lender.

           (d) Borrower shall assist any Lender permitted to sell assignments or
participations under this Section 10.1 as reasonably required to enable the
assigning or selling Lender to effect any such assignment or participation,
including the execution and delivery of any and all agreements, notes and other
documents and instruments as shall be requested and, if requested by Agent, the
preparation of informational materials for, and the participation of management
in meetings with, potential assignees or participants. Borrower shall certify
the correctness, completeness and accuracy of all descriptions of Borrower and
its affairs contained in any selling materials provided by them and all other
information provided by them and included in such materials.

           (e) A Lender may furnish any information concerning Borrower in the
possession of such Lender from time to time to assignees and participants
(including prospective assignees and participants); provided, that the recipient
of any material non-public information concerning Borrower shall agree to treat
such information as confidential.

                                       74
<PAGE>

           (f) So long as no Event of Default shall have occurred and be
continuing, no Lender shall assign or sell participations in any portion of its
Loans or Commitment to a potential Lender or participant, if, as of the date of
the proposed assignment or sale, the assignee Lender or participant would be
subject to capital adequacy or similar requirements, increased costs, an
inability to fund LIBOR Advances, or withholding taxes.

       10.2 Agent's Reliance Etc. Neither Agent nor any of its Affiliates nor
any of their respective directors, officers, agents or employees shall be liable
for any action taken or omitted to be taken by it or them under or in connection
with this Agreement or the other Transaction Documents, except for damages
solely caused by its or their own gross negligence or willful misconduct as
finally determined by a court of competent jurisdiction. Without limitation of
the generality of the foregoing, Agent: (a) may treat the payee of any Note as
the holder thereof until Agent receives written notice of the assignment or
transfer thereof signed by such payee and in form satisfactory to Agent; (b) may
consult with legal counsel, independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (c) makes no warranty or representation to any Lender
and shall not be responsible to any Lender for any statements, warranties or
representations made in or in connection with this Agreement or the other
Transaction Documents; (d) shall not have any duty to ascertain or to inquire as
to the performance or observance of any of the terms, covenants or conditions of
this Agreement or the other Transaction Documents on the part of Borrower, BTITC
or any of their Affiliates or to inspect the Collateral (including the books and
records) of Borrower; (e) shall not be responsible to any Lender for the due
execution, legality, validity, enforceability, genuineness, sufficiency or value
of this Agreement or the other Transaction Documents or any other instrument or
document furnished pursuant hereto or thereto; and (f) shall incur no liability
under or in respect of this Agreement or the other Transaction Documents by
acting upon any notice, consent, certificate or other instrument or writing
(which may be by telecopy, telegram, cable or telex) believed by it to be
genuine and signed or sent by the proper party or parties.

       10.3 Bank of America Affiliates. With respect to its commitments
hereunder, Bank of America shall have the same rights and powers under this
Agreement and the other Transaction Documents as any other Lender and may
exercise the same as though it were not Agent; and the term "Lender" or
"Lenders" shall, unless otherwise expressly indicated, include Bank of America
in its individual capacity. Bank of America and its Affiliates may lend money
to, invest in, and generally engage in any kind of business with, Borrower,
BTITC or any of their Affiliates and any Person who may do business with or own
securities of any such party, all as if Bank of America were not Agent and
without any duty to account therefor to Lenders. Bank of America and its
Affiliates may accept fees and other consideration from Borrower, BTITC or any
of their Affiliates for services in connection with this Agreement or otherwise
without having to account for the same to Lenders. Each Lender acknowledges the
potential conflict of interest between Bank of America as a Lender holding
disproportionate interests in the Loans and Bank of America as Agent.

       10.4 Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon Agent or any other Lender and based on
such documents and information as it has deemed appropriate, made its own credit
and financial analysis of Borrower and its own decision to enter into this
Agreement. Each Lender also acknowledges that it will,



                                       75
<PAGE>

independently and without reliance upon Agent or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement. Each Lender acknowledges the potential conflict of interest of
each other Lender as a result of Lenders holding disproportionate interests in
the Loans, and expressly consents to, and waives any claim based upon, such
conflict of interest.

       10.5 Indemnification. Lenders agree to indemnify Agent (to the extent not
reimbursed by Borrower and without limiting the obligations of Borrower
hereunder), ratably according to their respective Commitment Percentages, from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by, or asserted against
Agent in any way relating to or arising out of this Agreement or any other
Transaction Document or any action taken or omitted by Agent in connection
therewith; provided, however, that no Lender shall be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting solely from Agent's gross
negligence or willful misconduct as finally determined by a court of competent
jurisdiction. Without limiting the foregoing, each Lender agrees to reimburse
Agent promptly upon demand for its ratable share of any out-of-pocket expenses
(including counsel fees) incurred by Agent in connection with the preparation,
execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement and each
other Transaction Document, to the extent that Agent is not reimbursed for such
expenses by Borrowers.

       10.6 Successor Agent. Agent may resign at any time by giving not less
than thirty (30) days' prior written notice thereof to Lenders and Borrower.
Upon any such resignation, the Required Lenders shall have the right to appoint
a successor Agent. If no successor Agent shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after
the resigning Agent's giving notice of resignation, then the resigning Agent
may, on behalf of Lenders, appoint a successor Agent, which shall be a Lender,
if a Lender is willing to accept such appointment, or otherwise shall be a
commercial bank or financial institution or a Subsidiary of a commercial bank or
financial institution if such commercial bank or financial institution is
organized under the laws of the United States of America or of any State thereof
and has a combined capital and surplus of at least $300,000,000. If no successor
Agent has been appointed pursuant to the foregoing, by the thirtieth (30th) day
after the date such notice of resignation was given by the resigning Agent, such
resignation shall become effective and the Required Lenders shall thereafter
perform all the duties of Agent hereunder until such time, if any, as the
Required Lenders appoint a successor Agent as provided above. Any successor
Agent appointed by Required Lenders hereunder shall be subject to the approval
of Borrower, such approval not to be unreasonably withheld or delayed; provided
that such approval shall not be required if a Default or an Event of Default
shall have occurred and be continuing. Upon the acceptance of any appointment as
Agent hereunder by a successor Agent, such successor Agent shall succeed to and
become vested with all the rights, powers, privileges and duties of the
resigning Agent. Upon the earlier of the acceptance of any appointment as Agent
hereunder by a successor Agent or the effective date of the resigning Agent's
resignation, the resigning Agent shall be discharged from its duties and
obligations under this Agreement and the other Transaction Documents, except
that any indemnity rights or other rights in favor of



                                       76
<PAGE>

such resigning Agent shall continue. After any resigning Agent's resignation
hereunder, the provisions of this Article 10 shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was Agent under this
Agreement and the other Transaction Documents. Agent may be removed at the
written direction of the holders (other than Agent) of two-thirds or more of the
Commitments (excluding Agent's Commitment); provided that in so doing, such
Lenders shall be deemed to have waived and released any and all claims they may
have against Agent.

       10.7 Setoff and Sharing of Payments. In addition to any rights now or
hereafter granted under applicable law and not by way of limitation of any such
rights, upon the occurrence and during the continuance of any Event of Default,
each Lender and each holder of any Note is hereby authorized at any time or from
time to time, without notice to Borrower or to any other Person, any such notice
being hereby expressly waived, to set off, subject to the terms and conditions
of the Intercreditor Agreement and to appropriate and to apply any and all
balances held by it at any of its offices for the account of Borrower
(regardless of whether such balances are then due to Borrower) and any other
properties or assets any time held or owing by that Lender or that holder to or
for the credit or for the account of Borrower against and on account of any of
the Obligations which are not paid when due. Any Lender or holder of any Note
exercising a right to set off or otherwise receiving any payment on account of
the Obligations in excess of its Commitment Percentage shall purchase for cash
(and the other Lenders or holders shall sell) such participations in each such
other Lender's or holder's Commitment Percentage of the Obligations as would be
necessary to cause such Lender to share the amount so set off or otherwise
received with each other Lender or holder in accordance with their respective
Commitment Percentage. Borrower agrees, to the fullest extent permitted by law,
that (a) any Lender or holder may exercise its right to set off with respect to
amounts in excess of its Commitment Percentage of the Obligations and may sell
participations in such amount so set off to other Lenders and holders and (b)
any Lender or holders so purchasing a participation in the Loans made or other
Obligations held by other Lenders or holders may exercise all rights of set-off,
bankers' lien, counterclaim or similar rights with respect to such participation
as fully as if such Lender or holder were a direct holder of the Loans and the
other Obligations in the amount of such participation. Notwithstanding the
foregoing, if all or any portion of the setoff amount or payment otherwise
received is thereafter recovered from the Lender that has exercised the right of
set-off, the purchase of participations by that Lender shall be rescinded and
the purchase price restored without interest.

       10.8 Advances; Payments; Non-Funding Lenders; Information; Actions in
Concert.

           (a) Advances, Payments.

                  (i) Each Lender shall make the amount of such Lender's
Commitment Percentage of each Advance available to Agent in same day funds by
wire transfer to Agent's account as set forth in Annex D not later than 3:30
p.m. (Charlotte, NC time) on the requested funding date, in the case of a Prime
Rate Option Advance and not later than 10:00 a.m. (Charlotte, NC time) on the
requested funding date in the case of a LIBOR Advance. After receipt of such
wire transfers (or, in the Agent's sole discretion, before receipt of such wire
transfers), subject to the terms hereof, Agent shall make the requested Advance
to the Borrower.


                                       77
<PAGE>

All payments by each Lender shall be made without setoff, counterclaim or
deduction of any kind.

                  (ii) On each day that payments are received with respect to
the Loans (each, a "Settlement Date"), Agent will advise each Lender by
telephone, or telecopy of the amount of such Lender's Commitment Percentage of
principal, interest and Fees paid for the benefit of Lenders with respect to
each applicable Loan. Provided that such Lender has made all payments required
to be made by it and has purchased all participations required to be purchased
by it under this Agreement and the other Loan Documents as of such Settlement
Date, Agent will pay to each Lender such Lender's Commitment Percentage of
principal, interest and Fees paid by Borrower since the previous Settlement Date
for the benefit of that Lender on the Loans held by it. Such payments shall be
made by wire transfer to such Lender's account (as specified by such Lender in
the applicable Assignment Agreement) not later than 2:00 p.m. (Charlotte, NC
time) on the next Business Day following each Settlement Date.

           (b) Availability of Lender's Commitment Percentage. Agent may assume
that each Lender will make its Commitment Percentage of each Advance available
to Agent on each funding date. If such Commitment Percentage is not, in fact,
paid to Agent by such Lender when due, Agent will be entitled to recover such
amount on demand from such Lender without set-off, counterclaim or deduction of
any kind. If any Lender fails to pay the amount of its Commitment Percentage
forthwith upon Agent's demand, Agent shall promptly notify Borrower and Borrower
shall immediately repay such amount to Agent. Nothing in this Section 10.8(b) or
elsewhere in this Agreement or the other Transaction Documents shall be deemed
to require Agent to advance funds on behalf of any Lender or to relieve any
Lender from its obligation to fulfill its Commitments hereunder or to prejudice
any rights that Borrower may have against any Lender as a result of any default
by such Lender hereunder. To the extent that Agent advances funds to Borrower on
behalf of any Lender and is not reimbursed therefor on the same Business Day as
such Advance is made, Agent shall be entitled to retain for its account all
interest accrued on such Advance until reimbursed by the applicable Lender.

           (c) Return of Payments.

                  (i) If Agent pays an amount to a Lender under this Agreement
in the belief or expectation that a related payment has been or will be received
by Agent from Borrower and such related payment is not received by Agent, then
Agent will be entitled to recover such amount from such Lender on demand without
set-off, counterclaim or deduction of any kind.

                  (ii) If Agent determines at any time that any amount received
by Agent under this Agreement must be returned to Borrower or paid to any other
Person pursuant to any insolvency law or otherwise, then, notwithstanding any
other term or condition of this Agreement or any other Transaction Document,
Agent will not be required to distribute any portion thereof to any Lender. In
addition, each Lender will repay to Agent on demand any portion of such amount
that Agent has distributed to such Lender, together with interest at such rate,
if any, as Agent is required to pay to Borrower or such other Person, without
set-off, counterclaim or deduction of any kind.


                                       78
<PAGE>



           (d) Funding Lenders. The failure of any Lender (such Lender, a
"Non-Funding Lender") to make any Advance or to purchase any participation to be
made or purchased by it on the date specified therefor shall not relieve any
other Lender (each such other Lender, an "Other Lender") of its obligations to
make such Advance or purchase such participation on such date, but neither any
other Lender nor Agent shall be responsible for the failure of any Non-Funding
Lender to make an Advance to be made, or to purchase a participation to be
purchased, by such Non-Funding Lender, and no Non-Funding Lender shall have any
obligation to Agent or any other Lender for the failure by such Non-Funding
Lender. Notwithstanding anything set forth herein to the contrary, a Non-Funding
Lender shall not have any voting or consent rights under or with respect to any
Transaction Document or constitute a "Lender" (or be included in the calculation
of "Required Lenders" hereunder) for any voting or consent rights under or with
respect to any Transaction Document.

           (e) Dissemination of Information. Agent will use reasonable efforts
to provide Lenders with any notice of Default or Event of Default received by
Agent from, or delivered by Agent to, Borrower or any other party to any other
Transaction Document, with notice of any Event of Default of which Agent has
actually become aware and with notice of any action taken by Agent following any
Event of Default; provided, however, Agent shall not be liable to any Lender for
any failure to do so, except to the extent that such failure is attributable
solely to Agent's gross negligence or willful misconduct as finally determined
by a court of competent jurisdiction.

           (f) Actions in Concert. Anything in this Agreement to the contrary
notwithstanding, each Lender hereby agrees with each other Lender that no Lender
shall take any action to protect or enforce its rights arising out of this
Agreement or the Notes (including exercising any rights of set-off) without
first obtaining the prior written consent of Agent or Required Lenders, it being
the intent of Lenders that any such action to protect or enforce rights under
this Agreement and the Notes shall be taken in concert and at the direction or
with the consent of Agent.

11. MISCELLANEOUS

       11.1 Complete Agreement; Modification of Agreement

           (a) This Agreement and the other Transaction Documents constitute the
complete agreement between the parties with respect to the subject matter hereof
and thereof, supersede all prior agreements, commitments, understandings or
inducements (oral or written, expressed or implied), and may not be modified,
altered or amended except as provided in this Section 11.1. Except as set forth
in subsection (b) below, any term, covenant, agreement or condition of this
Agreement or any of the Transaction Documents may be amended or waived, and any
departure therefrom may be consented to by the Required Lenders, if, but only
if, such amendment, waiver or consent is in writing signed by the Agent or
Required Lenders (if applicable) and the GECC agent under the GECC Loan
Agreement, if applicable, pursuant to the Intercreditor Agreement and, in the
case of an amendment (other than an amendment described in subsection (d)
below), by Borrower, and in any such event, the failure to observe, perform or
discharge any such term, covenant, agreement or condition (whether such
amendment is executed or such waiver or consent is given before or after such
failure) shall not be construed as a breach of such term,


                                       79
<PAGE>


covenant, agreement or condition or as a Default or an Event of Default. Unless
otherwise specified in such waiver or consent, a waiver or consent given
hereunder shall be effective only in the specific instance and for the specific
purpose for which given. In the event that any such waiver or amendment is
requested by Borrower, Agent and Lenders may require and charge a fee in
connection therewith and consideration thereof in such amount as shall be
determined by Agent and the Required Lenders in their discretion.

           (b) No amendment, modification, termination or waiver of or consent
with respect to any provision of this Agreement which waives compliance with the
conditions precedent set forth in Section 2.2 to the making of any Loan shall be
effective unless the same shall be in writing and signed by Agent, Lenders and
Borrower. Notwithstanding anything contained in this Agreement to the contrary,
no waiver or consent with respect to any Default (if in connection therewith
Agent or Lenders, as the case may be, have exercised its or their right to
suspend the making or incurrence of further Advances) or any Event of Default
shall be effective for purposes of the conditions precedent to the making of
Loans set forth in Section 2.2 unless the same shall be in writing and signed by
Agent.

           (c) No amendment, modification, termination or waiver shall, unless
in writing and signed by Agent and each Lender directly affected thereby, do any
of the following: (i) increase the principal amount of any Lender's Commitment
(which action shall be deemed to directly affect all Lenders): (ii) reduce the
principal of, rate of interest on or Fees payable with respect to any Loan of
any affected Lender; (iii) extend the final maturity date of any Loan of any
affected Lender; (iv) waive, forgive, defer, extend or postpone any payment of
interest or Fees as to any affected Lender; (v) release any Guaranty or, except
as otherwise permitted herein or in the other Transaction Documents, permit
Borrower to sell or otherwise dispose of any Collateral with a value exceeding
$5,000,000 in the aggregate (which action shall be deemed to directly affect all
Lenders); (vi) change the percentage of the Commitments or of the aggregate
unpaid principal amount of the Loans which shall be required for Lenders or any
of them to take any action hereunder; and (vii) amend or waive this Section 11.1
or the definitions of the term "Required Lenders" insofar as such definition
affects the substance of this Section 11.1. Furthermore, no amendment,
modification, termination or waiver affecting the rights or duties of Agent
under this Agreement or any other Transaction Document shall be effective unless
in writing and signed by Agent, in addition to Lenders required hereinabove to
take such action. Each amendment, modification, termination or waiver shall be
effective only in the specific instance and for the specific purpose for which
it was given. No amendment, modification, termination or waiver shall be
required for Agent to take additional Collateral pursuant to any Transaction
Document. No amendment, modification, termination or waiver of any provision of
any Note shall be effective without the written concurrence of the holder of
that Note. No notice to or demand on Borrower in any case shall entitle Borrower
or any party to any other Transaction Document to any other or further notice or
demand in similar or other circumstances. Any amendment, modification,
termination, waiver or consent effected in accordance with this Section 11.1
shall be binding upon each holder of the Notes at the time outstanding and each
future holder of the Notes.

           (d) If, in connection with any proposed amendment, modification,
waiver or termination (a "Proposed Change"): (i) requiring the consent of all
affected Lenders, the consent of Required Lenders is obtained, but the consent
of other Lenders whose consent is required is



                                       80
<PAGE>


not obtained (any such Lender whose consent is not obtained as described in this
clause (i) and in clause (ii) below being referred to as a "Non-Consenting
Lender"), or (ii) requiring the consent of Required Lenders, the consent of

Agreement or any other Transaction Document shall be deemed to have been
suspended or waived by Agent or any Lender, unless such waiver or suspension is
by an instrument in writing signed by an officer of or other authorized employee
of Agent or any Lender and directed to Borrower specifying such suspension or
waiver.

       11.4 Remedies. Agent's and Lenders' rights and remedies under this

and in accordance with resolutions duly adopted by Borrower's Board of
Directors, and Agent shall be entitled to assume the authority of each signature

person acting in reliance of such signature shall have actual knowledge of the

separate counterparts, each of which shall, collectively and separately,
constitute one agreement.

       11.12 Time of the Essence. Time is of the essence of this Agreement and
each of the other Transaction Documents.

       11.13 GOVERNING LAW. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN ANY OF THE
LOAN DOCUMENTS, IN ALL RESPECTS, INCLUDING, WITHOUT LIMITATION, ALL MATTERS OF
CONSTRUCTION, VALIDITY AND PERFORMANCE, THIS AGREEMENT AND THE OBLIGATIONS
ARISING HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF CALIFORNIA APPLICABLE TO CONTRACTS MADE AND
PERFORMED IN SUCH STATE, AND ANY APPLICABLE LAWS OF THE UNITED STATES OF
AMERICA. BORROWER HEREBY CONSENTS AND AGREES THAT THE STATE OR FEDERAL COURTS
LOCATED IN CALIFORNIA SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE
ANY CLAIMS OR DISPUTES BETWEEN BORROWER, AGENT AND LENDERS PERTAINING TO THIS
AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR TO ANY MATTER ARISING OUT OF OR
RELATED TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS; PROVIDED, THAT
AGENT, LENDERS AND BORROWER ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY
HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF CALIFORNIA; AND FURTHER PROVIDED,
THAT NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE LENDERS OR
AGENT FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION
TO COLLECT THE OBLIGATIONS, TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY
FOR THE OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF
AGENT OR LENDERS. BORROWER EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH
JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND BORROWER
HEREBY WAIVES ANY OBJECTION WHICH BORROWER MAY HAVE BASED UPON LACK OF PERSONAL
JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE
GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH
COURT. BORROWER HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND
OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH
SUMMONS, COMPLAINTS AND OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED
MAIL ADDRESSED TO BORROWER AT THE ADDRESS SET FORTH IN SECTION 11.8 OF THIS
AGREEMENT AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE EARLIER OF
BORROWER'S ACTUAL RECEIPT THEREOF OR THREE (3) DAYS AFTER DEPOSIT IN THE U.S.
MAILS, PROPER POSTAGE PREPAID.

       11.14 WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN CONNECTION WITH
COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN
EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL
LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT THEIR


                                       85
<PAGE>



DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO
ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF
ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER SOUNDING IN
CONTRACT, TORT, OR OTHERWISE BETWEEN AGENT, LENDERS AND BORROWER ARISING OUT OF,
CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
BETWEEN THEM IN CONNECTION WITH, THIS AGREEMENT OR ANY OF THE OTHER LOAN
DOCUMENTS OR THE TRANSACTIONS RELATED THERETO.

       11.15 Intercreditor Agreement. In the case of any conflict between the
terms of this Agreement or any other Loan Document and the Intercreditor
Agreement relating to matters which are subject to the Intercreditor Agreement,
the terms of the Intercreditor Agreement shall govern and control.
