               TRANSACTION NETWORK SERVICES, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1998
                                   (Unaudited)

1.  GENERAL

         Transaction Network Services, Inc. (the "Company" or "TNS") was
incorporated in August 1990 to build and operate a communications network
focused on the network services needs of the POS
(Point-of-Sale/Point-of-Service) transaction processing industry. In June 1994,
the Company acquired Fortune Telecommunications, Inc. ("FTI") of Ft. Lauderdale,
Florida, which provides customers in the telecommunications industry with
telephone call fraud control, billing validation, and other services. In June
1996, the Company formed Transaction Network Services Limited ("TNSL"), a
majority-owned subsidiary located in Dublin, Ireland. TNSL provides POS network
services in Ireland and serves as TNS' European technology and marketing center
to support current and future European operations.

         The Company currently operates four divisions: (1) The POS Division
which includes the Company's TransXpress(R) network services for the POS
transaction processing industry, (2) The Telecom Services Division ("TSD") which
includes FTI's CARD*TEL(R) telephone call billing validation and fraud control
services and other services targeting primarily the telecommunications industry,
(3) The Financial Services Division ("FSD") which provides TNS FastLink(R) Data
Services in support of the Financial Information eXchange ("FIX") messaging
protocol and other transaction oriented trading applications primarily to the
financial services community, and (4) The International Systems Division ("ISD")
which markets the Company's products and services internationally.

         The condensed consolidated financial statements included herein have
been prepared by the Company, without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission ("SEC") and include, in
the opinion of the Company, all adjustments, consisting of normal recurring
adjustments, necessary for a fair presentation of interim period results.
Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted pursuant to such rules and regulations. The
Company believes that its disclosures are adequate to make the information
presented not misleading. These condensed financial statements should be read in
conjunction with the financial statements and notes thereto included in the
Company's Annual Report on Form 10-K. The results of operations for the three
and nine month periods ended September 30, 1998 and 1997 are not necessarily
indicative of the results to be expected for the full year.


2. ACQUISITIONS

OmniLink Communications Corporation ("OmniLink")

         On July 1, 1998, the Company acquired substantially all of the assets
and assumed certain liabilities (composed principally of trade accounts payable
and accrued liabilities) of OmniLink, a Michigan corporation. The consideration
paid to OmniLink, after arm's-length negotiations, was $2.5 million which was
composed of (a) approximately $600,000 in cash, plus direct acquisition costs,
and (b) approximately $1.9 million by cancellation of a note payable from
OmniLink to the Company. A limited partnership controlled by the Company's Chief
Executive Officer and a venture capital firm, one of whose partners is a Company
director, each are minority shareholders in OmniLink. The terms of the
acquisition also include a royalty payment from the Company to OmniLink of up to
approximately 5% of the price per unit based upon future OmniLink product sales.
The royalty agreement will terminate upon the earlier of the date that OmniLink
has received royalties aggregating $5,000,000 or June 30, 2001. The OmniLink
acquisition is being accounted for as a purchase. Amounts allocated to
intangible assets (goodwill) in the purchase accounting are being amortized on a
straight-line basis over a period of 10 years. The purchase price allocations
have been completed on a preliminary basis and are subject to adjustment, should
new or additional facts about the business become known.

SunTech Processing Systems, LLC

         On February 27, 1998, the Company acquired certain assets and assumed
certain liabilities of SunTech Processing Systems, LLC ("SunTech"), a Texas
limited liability company. The total consideration paid after arm's-length
negotiations was $17.5 million, composed of (a) $12.25 million in cash, and (b)
287,474 shares of the Company's common stock valued at $5.25 million. Prior to
the acquisition, SunTech was primarily engaged in the business of providing
transaction processing services for automated teller machines ("ATMs") and
developing additional communications technologies for ATMs. The Company acquired
Suntech's dial-up ATM transaction processing segment (the "Processing Business")
and SunTech's proprietary host-interface processing ("HIP") technology segment,
which allows for leased line ATMs to be converted into dial-up ATMs. The SunTech
acquisition is being accounted for as a purchase. Amounts allocated to
intangible assets (including customer contracts, non-compete agreements,
software and goodwill) in the purchase accounting are being amortized on a
straight-line basis over periods ranging from 2 to 10 years. The purchase price
allocations have been completed on a preliminary basis and are subject to
adjustment, should new or additional facts about the business become known.

         On July 23, 1998, the Company sold the Processing Business to Money
Access Service Inc., a wholly-owned subsidiary of Electronic Payment Services,
Inc. ("EPS") and a customer of the Company. The consideration received after
arm's-length negotiations was $6.0 million in cash and certain equipment and
accounts receivable of the Processing Business. The terms of the acquisition
also included: (a) a software license whereby the Company was granted a
non-exclusive, perpetual right to use certain software associated with the
Processing Business at locations outside the United States; and (b) an agreement
with EPS whereby EPS committed, under certain circumstances, to purchase certain

         On September 10, 1998, the Company acquired from AT&T Corp. ("AT&T")
the right to provide services under certain customer service contracts relating
to AT&T's Transaction Access Service ("TAS") as well as certain equipment used
by AT&T in furnishing this service. The consideration paid for these assets
after arm's-length negotiations was approximately $64.3 million in cash, plus
direct acquisition costs. The source of the funds used to acquire these assets
was a $75 million revolving credit facility (the "Revolver') obtained in
connection with this transaction. The Company also entered into a service
agreement with AT&T under which the Company agreed to purchase a minimum of $10
million in communications services per year from AT&T during the two-year period
beginning February 1, 1999. The transaction also included a limited
non-competition agreement and a customer referral arrangement with AT&T. Under
the referral arrangement the Company has agreed to compensate AT&T based upon
future revenues generated by referrals of sales prospects to the Company by
AT&T. In connection with the transaction, the Company and AT&T also entered into
a settlement agreement whereby the Company agreed to dismiss with prejudice its
complaint filed against AT&T with the Federal Communications Commission.

         Under the Asset Purchase Agreement the Company will purchase 
transitional communication and other transitional services from AT&T 
including network operation, engineering support and billing services until 
the TAS customers are migrated from the TAS network to the TNS network. Under 
this arrangement, AT&T continues to prepare the TAS customer billings. 
Accordingly, the $3.5 million of TAS revenue recorded by the Company relating 
to the twenty-day period from September 10, 1998 to September 30, 1998 was 
not billed until mid-October. As a result, the Company had not collected any 
of the $3.5 million of TAS accounts receivable prior to September 30, 1998 
and the entire balance was included in accounts receivable at September 30, 
1998.

         The TAS acquisition is being accounted for as a purchase. Amounts
allocated to intangible assets (including customer contracts, a non-compete
agreement, and goodwill) in the purchase accounting are being amortized on a
straight-line basis over periods ranging from 3 to 20 years. The purchase price
allocations have been completed on a preliminary basis and are subject to
adjustment, should new or additional facts about the business become known.

         The $75 million Revolver provides for unsecured LIBOR or base rate
borrowings at the Company's option. A margin is added to the applicable LIBOR or
base rate based upon the Company's ratio of total debt to annualized operating
cash flow, as defined in the agreement. The interest rate at September 30, 1998
was 6.34% (LIBOR plus 75 basis points). LIBOR loan maturities range from 30 to
180 days. Interest on LIBOR loans is paid at expiration or, for loans with an
original maturity of greater than 90 days, both at 90 days from inception and on
expiration. Interest on base rate loans is paid on March 31, June 30, September
30, and December 31. The Revolver matures in September 2001 and is subject to
annual renewals thereafter. Borrowings may be repaid at any time without penalty
subject to minimum repayment amounts. The Revolver includes a commitment fee
based upon the average unused balance. The Revolver also includes certain
financial and non-financial restrictive covenants including minimum operating
cash flow requirements and limitations on investments, other borrowings, capital
expenditures and acquisitions. Acquisitions are subject to pro-forma covenant
compliance.

         The unaudited pro forma information for the periods set forth below
give effect to the SunTech transaction and the subsequent sale of the Processing
Business, and the OmniLink transaction as if they had occurred at the beginning
of each period. Pro forma financial information related to the TAS acquisition
is currently not available but is expected to be filed within the period when
required by the applicable SEC rules. The pro forma information is presented for
informational purposes only and is not necessarily indicative of the results of
operations that actually would have been achieved had the acquisition been
consummated as of that time (unaudited, 000's omitted):

Transaction Network Services (UK) Limited

         On September 1, 1998 the Company entered into a joint venture in the
United Kingdom with General Cable PLC. The venture is a majority owned
subsidiary of the Company and is named Transaction Network Services (UK) Limited
("TNSUK"). The Company purchased its 60% in TNSUK for approximately $4.0 million
in cash. General Cable contributed customer contracts, business relationships,
goodwill and certain network equipment in exchange for its 40% interest. The
customer contracts and goodwill are being amortized over 10 years on a straight
line basis. General Cable provides TNSUK certain telecommunication and
management services. TNSUK utilizes the Company's network technology, along with
technology acquired in the acquisition of certain assets of SunTech and
OmniLink, to provide point-of-sale and other transaction services in the UK.

AMNEX, Inc.

         On March 29, 1996, the Company completed an asset purchase from AMNEX,
Inc. ("AMNEX") of AMNEX's proprietary fraud-control system and related databases
used to provide fraud control and billing validation services. The transaction
also included a ten year exclusive service agreement and other agreements. The
Company paid approximately $1.5 million in cash for these assets.

         In December 1997, the Company entered into a consulting agreement with
AMNEX in exchange for certain revisions made to the exclusive service agreement.
The consulting agreement required an initial payment of approximately $180,000
and monthly payments of approximately $33,000 through June 30, 2002. The
consulting agreement provides that, in the case of a material breach by AMNEX,
the remaining unpaid monthly payments become immediately due and payable as
liquidated damages. To ensure payment of amounts under both the exclusive
service agreement and consulting agreement (collectively, the "Agreements"),
AMNEX executed instruction letters whereby AMNEX directed its billing agent to
pay the Company directly all amounts owed by AMNEX under the Agreements (the
"Directions to Pay"). The Directions to Pay are held in escrow by an escrow
agent. In May 1998, the Company delivered a notice of default to AMNEX for
non-payment of fees under the exclusive service agreement and consulting
agreement. The Company subsequently directed the escrow agent to deliver the
Directions to Pay to the billing agent. As is allowed by the escrow agreements,
AMNEX objected to the release of the Directions to Pay.

         On July 29, 1998, the Company filed arbitration proceedings with the
American Arbitration Association against AMNEX. The statement of claims alleges
that AMNEX breached various agreements with the Company and seeks damages and
injunctive relief. The statement of claims also seeks to have the escrow agent
release the Directions to Pay to the Company for delivery to AMEX's billing
agent. On November 6, 1998, AMNEX filed an answer to the statement of claims
denying the Company's claims and asserting as affirmative defenses that the
consulting agreement is unenforceable, that the liquidated damages provisions of
the consulting agreement are void as a penalty and that the Company is not
entitled to equitable relief. AMNEX also alleged, as a counter-claim that the
Company breached the consulting agreement and seeks the return of approximately
$92,000 paid under that agreement. The arbitration proceeding is scheduled to
begin in January 1999. While the Company recognizes the risks inherent in these
disputes and that the outcome is uncertain, management believes it is likely to
prevail in the arbitration proceedings on its merits.

         As of September 30, 1998, the Company has recorded net assets related
to AMNEX of approximately $1.8 million, including accounts receivable of
approximately $530,000 and intangible assets of approximately $1.3 million. Any
adjustment to the book value of these assets would result in a non-cash
accounting charge. Due to the material breach by AMNEX, the Company is entitled
to liquidated damages under the consulting agreement of approximately $1.6
million (none of which has been recorded by the Company), in addition to the
outstanding $530,000 of accounts receivable.

Other

         In July 1997, the Company entered into a $250,000 term loan with a
customer. The Company also paid this customer $500,000 for a software license to
use the customers' proprietary call monitoring and screening system and related
databases along with an option to purchase a minority interest in the customer.
The term loan is secured by certain collateral, interest is payable monthly, and
principal payments are due in three annual payments on the next three loan
anniversary dates. In connection with the term loan, the Company signed a debt
subordination agreement with the customer's senior creditor. In April 1998, the
Company received notice from the senior creditor that the borrower was in
default. Under the debt subordination agreement, the Company could not accept
payments from the customer for a period of 180 days. Management is negotiating
terms for payment under the note. In the event that the result of these
negotiations is unsatisfactory to management, management will consider all
options available to the Company under the note and applicable law. Management
believes that these assets are recoverable through future cash flows. Any
adjustment to the book value of these assets will result in a non-cash
accounting charge.

RESULTS OF OPERATIONS

 Revenues

         Total revenues increased by 49% to $25,582,000 for the three month
period ended September 30, 1998 from $17,170,000 for the same period in 1997 and
by 40% to $64,092,000 for the first nine months of 1998 from $45,729,000 for the
same period in 1997.

         POS services revenue increased by 47% to $16,404,000 from 
$11,145,000 for the three months ended September 30, 1998 versus the 
comparable period in 1997 and by 27% to $39,394,000 from $31,016,000 for the 
first nine months of 1998 versus the same period in 1997. The growth in POS 
services revenue resulted primarily from transaction volume and the 
associated $3.5 million of revenue recorded by the Company after the 
Company's September 10, 1998 acquisition of AT&T Corp's ("AT&T") Transaction 
Access Service ("TAS") and an increase in transaction volume and associated 
revenue from the Company's POS customers. POS transaction volume increased by 
45% to 907 million transactions for the third quarter of 1998 from 626 
million transactions in the third quarter of 1997. The TAS acquisition 
contributed 178 million transactions to POS transaction volume for the period 
from the acquisition date (September 10, 1998) to September 30, 1998. POS 
revenue per transaction was $0.016 for the three months ended September 30, 
1998 and $0.016 for the comparable period in 1997. POS revenue per 
transaction for the TAS transactions was $0.019 for the period from 
September 10, 1998 to September 30, 1998. Future average revenue per POS 
transaction will depend on the relative contribution to total transaction 
volume from each of the Company's sources of POS transactions and competitive 
factors.

                                       10

         Telecommunications services revenue increased by 38% to $7,925,000 from
$5,746,000 for the three months ended September 30, 1998 versus the comparable
period in 1997 and by 54% to $21,740,000 from $14,076,000 for the first nine
months of 1998 versus the same period in 1997. The growth in revenue was
primarily due to growth in queries processed for the Company's
telecommunications customers and from an increase in other telecommunications
services revenues, including LEConnect and SS7 services revenue.

         The Financial Services Division was formed in March 1997 and
contributed $662,000 of revenue for the three months ended September 30, 1998
versus $79,000 for the same period in 1997 and $1,285,000 for the first nine
months of 1998 compared to $136,000 for the same period in 1997. The growth in
revenue was due to growth in the number of customers and the associated
connections to the Company's Financial Services Network.

         International revenue contributed $591,000 in the third quarter of 1998
compared to $200,000 for the same period in 1997 and $1,673,000 for the first
nine months of 1998 compared to $498,000 for the same period in 1997. The
increase is due to increases in royalties, software license fees, equipment
sales and revenue associated with the September 1, 1998 formation of Transaction
Network Services (UK) Limited ("TNSUK"). TNSUK utilizes the Company's network
technology, along with technology acquired in the acquisition of certain assets
of Suntech and OmniLink, to provide point-of-sale and other transaction services
in the UK. TNSUK contributed $109,000 of revenue for the period from September
1, 1998 to September 30, 1998.

         In April 1998, the Company, through TNSL, acquired a 50% interest in
Atos Ireland Limited, which has been renamed Switchtran Limited ("Switchtran').
Switchtran provides processing services, primarily for cash withdrawals, made
from a network of automated teller machines ("ATM's") located throughout
Ireland. Switchtran is accounted for under the equity method of accounting.
Accordingly, the Company records its 50% share of Switchtran's net income, which
was $178,000 for the third quarter of 1998, as "Equity in Unconsolidated
Affiliate".

         The Company's majority owned Irish subsidiary - Transaction Network
Services Limited ("TNSL") provides POS network services in Ireland and serves as
TNSL's European technology and marketing center. Currently, TNSL's consolidated
losses are being absorbed and consolidated with the Company's operating results.
TNSL's consolidated losses were approximately $169,000 for the third quarter of
1998 compared to $161,000 for the same period in 1997 and $686,000 for the first
nine months of 1998 compared to $605,000 for the same period in 1997.

Cost of Network Services

         Cost of network services increased by 59% to $15,175,000 from
$9,540,000 for the three months ended September 30, 1998 versus the comparable
period in 1997 and by 45% to $37,049,000 from $25,562,000 for the first nine
months of 1998 versus the same period in 1997. This growth resulted primarily
from increases in usage charges and charges for billing validation information
resulting from increased transaction and query volumes including transactions
associated with the September 10, 1998 TAS acquisition.



                                       11
<PAGE>


         In connection with the TAS acquisition, and under the Asset Purchase 
Agreement (the "Agreement"), the Company negotiated an arrangement with AT&T 
for the purchase of transitional communication services and other 
transitional services including network operation, engineering support and 
billing services. Under this arrangement, AT&T provides the Company with 
these services until the TAS customers are migrated off of the TAS network 
and onto the Company's network. The transitional communication rates included 
in the Agreement determine the cost per transaction until the associated TAS 
transactions are migrated from the TAS network. These transitional 
communication services rates and the rates for other transitional services 
increase at specified periods per the Agreement. The rates for the 
transitional services are greater than the rates the Company separately 
negotiated with AT&T under the 800 communication services contract and the 
rates incurred when utilizing the Company's own 800 network. The Company 
believes that it will experience a cost of network services above historical 
levels while these transactions remain on the TAS network and the Company 
continues to be charged the transitional rates. Once the TAS customers are 
transitioned off of the TAS network and onto the Company's network the cost 
per transaction will be determined by the cost under the 800 communication 
services contract with AT&T, the Company's 800 service agreements with other 
vendors and the costs associated with the Company's own 800 network. The 
ultimate impact of these transitional rates for communications and other 
services is dependent upon many factors including the Company's ability to 
successfully transition customers from the TAS network to its network 
facilities, capacity on the Company's network, customer cooperation, seasonal 
issues primarily associated with the holiday season including a customer's 
potential resistance to migrating traffic during this period, successful 
testing of certain transaction protocols not previously carried by the 
Company's network, and the ability of AT&T to connect the Company's network 
equipment to AT&T's 800 service network on a timely basis.

         In May 1997, pursuant to the Telecommunications Act of 1996 (the "1996
Act"), the FCC implemented rules and regulations referred to as Access Charge
Reform ("Access Reform") that seek to reform the system of interstate access
charges and make it compatible with the competitive paradigm established by the
1996 Act. The initial phase of Access Reform was implemented in July 1997. The
initial phase of Access Reform resulted in a decrease in certain components of
the Company's variable cost per transaction, and as a result, lowered the
Company's network costs. The second and third phases of Access Reform were
implemented in January and July 1998, respectively. The second and third phases
of Access Reform resulted in an additional decrease in certain components of the
Company's variable cost per transaction; however, both phases increased certain
of the Company's fixed monthly recurring charges and instituted certain new
fixed charges. The changes in access charges instituted by the third phase of
Access Reform resulted in an increase in fixed charges which more than offset
the reduction in variable costs per transaction. Further changes to access
charges due to Access Reform are scheduled to be implemented in 1999 and 2000.
The Company believes that future revisions may reduce its network costs because
the Company believes the increased charges are not in accordance with the spirit
of Access Reform which is intended to reduce overall access charges. However,
there can be no assurance that the future phases of Access Reform will result in
reductions to the Company's network costs and, in fact, they may increase. The
ultimate impact of Access Reform is dependent upon, among other things 1) the
ability to increase transaction volumes, which benefits the Company when lower
variable costs are instituted, 2) the nature and amount of fixed charges based
upon the number of connections in the Company's network, which increases network
costs, 3) any other future actions by the FCC, 4) the ability of the Company to
modify its network design to react to pricing revisions, and 5) the ability of
the Company to successfully defend and receive credits for improperly billed
charges. Accordingly, the impact of Access Reform on the Company's future
network access costs is unknown, and the Company cannot predict the timing,
outcome or effects of the FCC's regulations or of any future tariff matters.

Gross Profit

         Gross profit represented approximately 41% of total revenues for the
third quarter of 1998 compared to 44% for the same period in 1997 and 42% of
total revenues for the first nine months of 1998 compared to 44% for the same
period in 1997. The approximate 3% decrease in gross profit as a percentage of
total revenues for the comparable three-month periods primarily reflects the
impact of the transitional communications services rates associated with the
AT&T TAS acquisition. The gross margin percentage associated with the revenue
from the TAS acquisition was approximately 17%. The decrease in gross margin
percentage was also attributed to costs associated with the Company's expansion
of its own on-network "800" access service and the impact of certain fixed
charges instituted in the third phase of Access Reform. Except for capital9
expenditures, the Company expenses all of its network expansion and operating
costs as they are incurred.

         Future gross profit margin percentages depend on a number of factors 
including the ability to successfully migrate the TAS transactions from the 
TAS network and onto the Company's network on a timely manner, total 
transaction and query volume growth, the relative growth and contribution to 
total transaction volume of each of the Company's customers, the success of 
the Company's new service offerings including recent acquisitions, the timing 
and extent of the Company's network expansion and the timing and extent of 
any network cost reductions. In addition, any significant loss or significant 
reduction in the growth of transaction volume could lead to a decline in 
gross margin because significant portions of network costs are fixed costs. 
As a result, maintaining historical gross margin levels depends in part on 
growth in transaction volume generating economies of scale.

Engineering and Development

         Engineering and development ("E&D") expense increased by 49% to
$1,370,000 for the three months ended September 30, 1998 versus $921,000 for the
comparable period in 1997 and by 40% to $3,538,000 for the first nine months of
1998 from $2,534,000 for the same period in 1997. E&D expenses increased in
order to support the Company's revenue growth. E&D expenses represented
approximately 6% of revenues for the first nine months of 1998 and 1997 and
represented approximately 5% of revenues for the three months ended September
30, 1998 and September 30, 1997. The Company believes that future E&D expenses
as a percentage of revenues may decline due to the anticipated increase in
revenues associated with the TAS acquisition without a corresponding
proportional increase in E&D expenses. This impact will be partially offset by
an increase in E&D expenses associated with the OmniLink Communications
Corporation ("OmniLink") acquisition.

         On July 1, 1998, the Company acquired substantially all of the assets
of OmniLink. Prior to the acquisition, OmniLink developed, manufactured and
marketed modems for electronic commerce, Internet access, telecommuting and
advanced office communications. The Company has transferred its dial-up modem
technology acquired in the February 1998 acquisition of certain assets of
SunTech Processing Systems, LLC ("SunTech") to OmniLink. OmniLink has integrated
the SunTech modem technology into the OmniLink modems. This development effort
is intended to support the Company's strategy to offer dial-up ISDN access
services to both domestic and international customers. These customers have
traditionally relied upon more expensive leased line communications to process
transactions originated at both point-of-sale locations as well as automated
teller machines.

Year 2000

         The Company operates and utilizes various date-sensitive computer
applications and systems throughout its networks and businesses. The Company has
been cognizant of the Year 2000 issue for several years and has continually
attempted to maintain and/or upgrade its networks and computer systems to
recognize the Year 2000 and associated issues. The Company also recognizes that
there are risks with respect to embedded systems that are not necessarily part
of the Company's network or computer systems but contain microprocessor chips
which may not function properly with the change of the date to the Year 2000.
The management of the Company has formed an internal review team to resolve and
address Year 2000 issues not addressed in the normal course of business.
Procedures have been developed and are in place for assessing exposure and risk
which include testing current and future applications and systems, upgrading and
replacing non-compliant equipment and software and obtaining Year 2000
compliance statements from the Company's significant third parties including
material vendors and suppliers. Not all of the Company's significant third
parties have provided the Company with Year 2000 compliance statements. The
Company provides its customers with statements of readiness on the Year 2000 and
the Company believes that its primary networks and computer systems are
currently Year 2000 compliant. The Company also believes that the majority of
the services and products it offers are not affected by the Year 2000 date
change as there are no specific date functions nor date dependencies in such
products and services.

         As of September 30, 1998, the Company has surveyed a majority of its
business and critical systems and plans for the replacement of non-compliant
equipment and software have been implemented. At this time the cost of
replacement systems and modifications is not expected to be material and has
been incorporated into system upgrades scheduled to take place in the fourth
quarter of 1998 and first quarter of 1999. Any additional need for contingency
plans or back-up systems will be addressed and determined during the beginning
of calendar year 1999.

         The activities involved in the Company's Year 2000 project 
necessarily involve estimates and projections, as described above, of 
activities and resources that will be required in the future. These estimates 
and projections may be revised as work progresses on this project. 
Disruptions with respect to the computer systems of vendors or customers, 
which are outside the control of the Company, could impair the ability of the 
Company to obtain services or conduct business. If any of the significant 
third parties are not Year 2000 compliant and/or the Company fails to 
identify or replace non-compliant equipment or software and noncompliance 
causes a material disruption to the business of the Company, the Company's 
revenues and financial position could be materially adversely affected. There 
can be no assurance that the actions taken by the Company with respect to its 
network, computer systems or embedded systems will eliminate the numerous and 
varied risks associated with the Year 2000 date change. Further, there can be 
no assurance that the Company will not be adversely affected by any Year 2000 
related difficulties encountered by vendors or customers or by any downturn 
in the economy in general and there can be no assurance that the Year 2000 
will not have a material adverse effect on the Company's financial position 
or results of operations.

Selling, General and Administrative

         Selling, general and administrative ("SG&A") expenses increased by 58%
to $3,152,000 for the three months ended September 30, 1998 from $1,998,000 for
the same period of 1997 and by 35% to $8,337,000 for the first nine months of
1998 from $6,196,000 for the same period of 1997. SG&A expenses increased in
order to support the Company's revenue growth. SG&A expenses represented 13% of
revenues for the first nine months ended September 30, 1998 and 14% for the same
period of 1997. SG&A expenses represented 12% of revenues for the three months
ended September 30, 1998 and September 30, 1997. The Company believes that
future SG&A expenses as a percentage of revenues may decline due to the
anticipated increase in revenues associated with the TAS acquisition without a
corresponding proportional increase in SG&A expenses. This impact will be
partially offset by an increase in SG&A expenses associated with the OmniLink
acquisition.

Depreciation

         Depreciation expense increased by 47% to $1,805,000 for the three
months ended September 30, 1998 from $1,225,000 for the same period of 1997 and
by 37% to $4,792,000 for the first nine months of 1998 from $3,501,000 for the
same period of 1997. Depreciation expense increased primarily as a result of the
acquisition of capital equipment for network expansion to support the growth in
the Company's business.

Amortization of Intangibles

         The amortization of intangible assets increased by 166% to $1,031,000
for the three months ended September 30, 1998 from $388,000 for the same period
in 1997 and by 84% to $2,123,000 for the first nine months of 1998 from
$1,156,000 for the same period in 1997. The increase is attributable to the
amortization of intangible assets associated with the TAS, SunTech, and OmniLink
acquisitions. Amortization expense is expected to be approximately $1.9 million
per quarter over the next several years with approximately $1.1 million of this
amount relating to the TAS acquisition. See Note 2 to Item 1. - Financial
Statements for a discussion of events related to AMNEX and a customer.

Interest Income, net

         Net interest income decreased by 90% to $54,000 for the three months
ended September 30, 1998 from $542,000 for the same period in 1997 and decreased
by 34% to $910,000 for the first nine months of 1998 from $1,383,000 for the
same period in 1997. These decreases relate primarily to interest expense
associated with borrowing $64.3 million in connection with the September 10,
1998 TAS acquisition made under a $75 million revolving credit facility (the
"Revolver") and a reduction in invested funds. Interest expense under the
Revolver was approximately $255,000 for the period from September 10, 1998 to
September 30, 1998.

Income Taxes

         The effective tax rate decreased from 40% to 39% for the comparable
nine-month periods ended September 30, 1997 and September 30, 1998. The decrease
is primarily as a result of the reduction in TNSL's losses relative to the
Company's annual results. The Company has not recorded a tax asset for these
losses due to TNSL's brief operating history.

Earnings Per Share

         Diluted earnings per share decreased by 11% to $0.16 during the third
quarter of 1998 from $0.18 in the comparable 1997 quarter and increased by 13%
to $0.44 for the first nine months of 1998 from $0.39 for the comparable period
of 1997. The weighted average number of shares outstanding used to calculate
diluted earnings per share increased by 6% to 13,470,000 during the third
quarter of 1998 from 12,712,000 in the same period in 1997 and by 5% to
13,253,000 for the first nine months of 1998 from 12,574,000 for the same period
in 1997. Diluted shares outstanding increased primarily because of the 287,474
shares issued on February 27, 1998 in connection with the SunTech acquisition
and from an increase in stock options outstanding.

LIQUIDITY AND CAPITAL RESOURCES

         At September 30, 1998, principal sources of liquidity were cash and
cash equivalents of $10,765,000, short-term investments of $4,822,000 and
availability under the Revolver of approximately $10.7 million. Approximately
$4.0 million of cash and cash equivalents are held by TNSUK - a majority owned
subsidiary.

         Net cash provided by operating activities was $7,068,000 for the 
nine month period ended September 30, 1998, a decrease from $9,967,000 for 
the comparable period in 1997. The decrease is primarily from increases in 
net income, depreciation and accounts payable being more than offset by an 
increase in accounts receivable. TAS receivables accounted for $3.5 million 
of the $8.6 million increase in accounts receivable. For a transitional 
period, AT&T continues to prepare the TAS customer billings. Accordingly, the 
$3.5 million of TAS revenue recorded by the Company relating to the 
twenty-day period from September 10, 1998 to September 30, 1998 was not 
billed until mid-October. As a result, the Company had not collected any of 
the $3.5 million of TAS accounts receivable prior to September 30, 1998 and 
the entire balance was included in accounts receivable at September 30, 1998.

         Investing activities used $80,352,000 for the nine-month period ended
September 30, 1998 as compared to a use of $1,059,000 for the same period in
1997. The increase primarily relates to approximately $64.3 million paid for the
TAS acquisition, $6.2 million paid for the acquisition of certain SunTech assets
and approximately $600,000 paid for certain assets of OmniLink plus the
associated direct costs of these acquisitions. The Company purchased $11,462,000
of equipment for the nine-month period ended September 30, 1998 up from
$8,664,000 for the comparable period in 1997. The increase was primarily due to
purchases to increase network capacity related to the TAS acquisition and
transaction increases from existing customers, the expansion of the Company's
"800" network and the capital expenditure requirements of new service offerings.
In April 1998, the Company paid approximately $2.0 million for a 50% interest in
Switchtran. The net proceeds from the maturities of short and long-term
investments were $4,288,000 for the nine-month period ended September 30, 1998
and $7,705,000 for the nine months ended September 30, 1997.

         Financing activities provided $65,320,000 for the nine-month period 
ended September 30, 1998 as compared to use of $1,732,000 in the same period 
in 1997. On September 10, 1998, the Company borrowed $64.3 million for the 
TAS acquisition. The Company repaid $5.0 million of this amount in October 
1998. There were no borrowings in 1997. In 1997, the Company purchased 
211,500 shares of its common stock for approximately $2.5 million. There were 
no such purchases in 1998. Proceeds from the exercise of stock options and 
the Company's employee stock purchase plan increased from $759,000 for the 
first nine months of 1997 to $995,000 for the first nine months of 1998.

              The Company believes that its existing cash, investment balances,
availability under the Revolver, and cash flows generated by operations will be
sufficient to meet the capital needs of its current business activities for the
foreseeable future.

                           PART II - OTHER INFORMATION


Item 1.           Legal Proceedings. -

                  On October 28, 1997, the Company filed a formal complaint with
                  the Federal Communications Commission (the "FCC") against AT&T
                  Corp. ("AT&T"). The complaint alleged that AT&T, through the
                  provision of common carrier services to its Transaction Access
                  Services Group ("TAS Group") on terms and conditions more
                  favorable than those listed in AT&T's tariffs, violated
                  several provisions of the Communications Act of 1934 and the
                  FCC's rules. The complaint was dismissed in connection with
                  the Company's September 10, 1998 acquisition of certain TAS
                  Group assets.

         delivered for a fiscal quarter prior to the last date on which it can
         be delivered without violation of subsection 6.2(a), the Applicable
         Margin from such date until two Business Days after such Compliance
         Certificate is actually delivered shall be that applicable when the
         Leverage Ratio is in Level 3, (c) in the event that the actual Leverage
         Ratio for any period is subsequently determined to be greater than that
         set forth in the Compliance Certificate for such period, the Applicable
         Margin shall be recalculated for the applicable period based upon such
         actual Leverage Ratio and (d) notwithstanding anything to the contrary
         herein other than clause (b) above, until two Business Days after the
         last date that the Compliance Certificate for the period ended December
         31, 1998 is due in accordance with the provisions of subsection 6.2(a),
         the Applicable Margin shall be that applicable when the Leverage Ratio
         is in Level 1.

                  "Application":  in respect of each Letter of Credit
         issued by the Issuing Bank, an application, in such form as
         the Issuing Bank may specify from time to time, requesting
         issuance of such Letter of Credit.

                  "Asset Sale": means any sale, lease, transfer or other

<PAGE>


                  "Available Commitments":  at any particular time, an
         amount equal to the excess, if any, of the aggregate
         Commitments at such time over the sum of (a) the aggregate
         unpaid principal amount of the Loans outstanding at such
         time and (b) the L/C Obligations outstanding at such time.

                  "Base Rate": for any day, a rate per annum (rounded upwards,
         if necessary, to the next 1/100th of 1%) equal to the greater of (a)
         the Prime Rate in effect on such day and (b) the Federal Funds
         Effective Rate in effect on such day plus 1/2 of 1%. If for any reason
         the Agent shall have determined (which determination shall be
         conclusive absent manifest error) that it is unable to ascertain the
         Federal Funds Effective Rate for any reason, including the inability or
         failure of the Agent to obtain sufficient quotations in accordance with
         the definition of such term, the Base Rate shall be determined without
         regard to clause (b) of the first sentence of this definition until the
         circumstances giving rise to such inability no longer exist. Any change
         in the Base Rate due to a change in the Prime Rate or the Federal Funds
         Effective Rate shall be effective on the effective date of such change
         in the Prime Rate or the Federal Funds Effective Rate, as the case may
         be.

         the Lenders on a single date and as to which a single Interest Period
         is in effect.

                  "Borrowing Date": any Business Day on which a Loan is to be

         day on which commercial banks in Philadelphia, Pennsylvania are
         authorized or required by law to close; provided, however, that when
         used in connection with a Eurodollar Loan, the term "Business Day"
         shall also exclude any day on which banks are not open for dealings in
         the London interbank market.

                  "Capital Expenditure": an expenditure for any fixed asset or
         any improvements or additions thereto, including direct or indirect

a promissory note of the Borrower, substantially in the form of Exhibit A, with
appropriate insertions as to payee, date and principal amount (a "Note"),
payable to the order of 

                                      20

such Lender and in a principal amount equal to the amount of the initial
Commitment of such Lender. Each Lender is hereby authorized to record the date,
Type and amount of each Loan made by such Lender, each continuation thereof,
each conversion of all or a portion thereof to another Type, the date and amount
of each payment or prepayment of principal thereof and, in the case of
Eurodollar Loans, the length of each Interest Period with respect thereto, on
the schedule annexed to and constituting a part of its Note, and any such
recordation shall constitute prima facie evidence of the accuracy of the
information so recorded, provided that the failure of any Lender to make such
recordation (or any error in such recordation) shall not affect the obligations
of the Borrower hereunder or under such Note. Each Note (a) shall be dated the
Closing Date and (b) be stated to mature on the Termination Date.

                  2.3 Procedure for Loans. (a) The Borrower may borrow under the
Commitments during the Commitment Period on any Business Day. The Borrower shall
give the Agent irrevocable notice (which notice must be received by the Agent
prior to 10:00 A.M., Philadelphia time, three Business Days prior to the
requested Borrowing Date, if all or any part of the requested Loans are to be
initially Eurodollar Loans, or prior to 12:00 noon, Philadelphia time, one
Business Day prior to the requested Borrowing Date if all of the requested Loans
are to be initially Base Rate Loans), specifying in the Notice of Borrowing (i)
the amount to be borrowed, (ii) the requested Borrowing Date, (iii) whether the
borrowing is to be of Eurodollar Loans, Base Rate Loans or a combination thereof
and (iv) if the borrowing is to be entirely or partly of Eurodollar Loans, the
amount of such Loan(s) and the length of the initial Interest Period(s)
therefor. Each borrowing under the Commitments shall be in an amount equal to
$5,000,000 or increments of $1,000,000 thereafter (or, if the aggregate
Available Commitments at such time are less than $5,000,000, such lesser
amount).

                  Upon receipt of a Notice of Borrowing from the Borrower, the
Agent shall promptly notify each Lender thereof. Each Lender will make the
amount of its pro rata share of each borrowing (based on its Commitment
Percentage at that time) available to the Agent for the account of the Borrower
at the office of the Agent specified in subsection 10.2 prior to 12:00 Noon,
Philadelphia time, on the Borrowing Date requested by the Borrower in funds
immediately available to the Agent. Such borrowing will then be made available
to the Borrower by the Agent crediting the account of the Borrower on the books
of such office with the aggregate of the amounts made available to the Agent by
the Lenders and in like funds as received by the Agent.

                                       21

                  Unless the Agent shall have received notice from a Lender
prior to the date of any borrowing of Loans that such Lender will not make
available to the Agent such Lender's pro rata portion of such borrowing, the
Agent may assume that such Lender has made such portion available to the Agent
on the date of such borrowing in accordance with this subsection and the Agent
may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If and to the extent that such Lender shall not
have made such portion available to the Agent, such Lender and the Borrower
(without prejudice to the Borrower's rights against such Lender) severally agree
to repay to the Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Agent at (i) in the
case of the Borrower, the interest rate applicable at the time to the Loans
comprising such borrowing and (ii) in the case of such Lender, the Federal Funds
Effective Rate, provided, that, if such Lender shall not pay such amount within
three Business Days of such Borrowing Date, the interest rate on such overdue
amount shall, at the expiration of such three-Business Day period, be the rate
per annum applicable to Base Rate Loans. If such Lender shall repay to the Agent
such corresponding amount, such amount shall constitute such Lender's Loan as
part of such borrowing for purposes of this Agreement.

                           (b) If in a Notice of Borrowing no election as to the
Type of Loan is specified, then the requested Loan shall be a Base Rate Loan. If
a Eurodollar Loan is requested but no Interest Period with respect to such Loan
is specified in any such notice, then the Borrower shall be deemed to have
selected an Interest Period of one month's duration.

                  2.4 L/C Commitment. (a) Subject to the terms and conditions
hereof, the Issuing Bank, in reliance on the agreements of the other Lenders set
forth in subsection 2.7(a), agrees to issue letters of credit ("Letters of
Credit") in Dollars for the account of the Borrower on any Business Day during
the Commitment Period in such form as may be approved from time to time by the
Issuing Bank; provided, that no Letter of Credit shall be issued if, after
giving effect thereto (i) the aggregate amount of the Exposure at such time
would exceed the aggregate amount of the Commitments at such time or (ii) the
aggregate amount of the L/C Obligations at such time would exceed $10,000,000.

                           (b) Each Letter of Credit shall;

                                    (i) be denominated in Dollars and shall be
         (A) a standby letter of credit (a "Standby Letter of 

                                           22

<PAGE>


         Credit"), or (B) a commercial letter of credit issued in respect of
         the purchase of goods or services (a "Commercial Letter of Credit") by
         the Borrower or any Subsidiary in the ordinary course of business; and

                                    (ii) expire no later than the earlier of (A)
         one year (in the case of Standby Letters of Credit) or 180 days (in the
         case of Commercial Letters of Credit) after its date of issuance and
         (B) 5 Business Days prior to the Termination Date.

                           (c) Each Letter of Credit shall be subject to the
Uniform Customs and, to the extent not inconsistent therewith, the laws of the
Commonwealth of Pennsylvania.

                           (d) The Issuing Bank shall not at any time be
obligated to issue any Letter of Credit hereunder if such issuance would
conflict with, or cause the Issuing Bank or any L/C Participant to exceed any
limits imposed by, any applicable Requirement of Law.

                           (e) Notwithstanding the provisions of this subsection
2.4, the Lenders and the Borrower hereby agree that the Issuing Bank may issue
upon the Borrower's request, one or more Letter(s) of Credit which by its or
their terms may be extended for additional periods of up to one year each
provided that (i) the initial expiration date (or any subsequent expiration
date) of each such Letter of Credit is not later than 5 Business Days prior the
Termination Date, and (ii) renewal of such Letters of Credit, at the Issuing
Bank's discretion, shall be available upon written request from the Borrower to
the Issuing Bank at least 30 days (or such other time period as agreed by the
Borrower and the Agent) before the date upon which notice of renewal is
otherwise required.

                  2.5 Procedure for Issuance of Letters of Credit. The Borrower
may from time to time request that the Issuing Bank issue a Letter of Credit by
delivering to the Issuing Bank at its office for notices specified herein an
Application therefor, completed to the satisfaction of the Issuing Bank, and
such other certificates, documents and other papers and information as the
Issuing Bank may reasonably request. Upon receipt by the Issuing Bank of any
Application, the Issuing Bank will process such Application and the
certificates, documents and other papers and information delivered to it in
connection therewith in accordance with its customary procedures and shall
promptly issue the Letter of Credit requested thereby (but in no event shall the
Issuing Bank be required to issue any Letter of Credit earlier than (a) with
respect to Standby Letters of Credit, three (3) Business Days, and (b) with
respect to Commercial Letters of Credit, one 

                                       23

<PAGE>


Business Day, after its receipt of the Application therefor and all such other
certificates, documents and other papers and information relating thereto) by
issuing the original of such Letter of Credit to the beneficiary thereof or as
otherwise may be agreed by the Issuing Bank and the Borrower.

                  2.6 Fees, Commissions and Other Charges. (a) The Borrower
shall pay to the Agent, for the account of the Lenders (including the Issuing
Bank) pro rata according to their respective Commitment Percentages, a letter of
credit commission with respect to each Letter of Credit, computed at a rate
equal to the then Applicable Margin for Eurodollar Loans on the daily average
undrawn face amount of such Letter of Credit (computed on the basis of the
actual number of days such Letter of Credit is outstanding in a year of 360
days). Such commissions shall be payable in arrears on the last Business Day of
each March, June, September and December to occur after the date of issuance of
each Letter of Credit, and on the Termination Date or such earlier date as the
Commitments are terminated, and shall be nonrefundable. The Borrower shall also
pay to the Agent, for the account of the Issuing Bank, in respect of each Letter
of Credit issued by the Issuing Bank a fronting fee for the period from and
including the date of issuance of such Letter of Credit to and including the
date of termination of such Letter of Credit computed at the rate of .125% per
annum on the daily average undrawn face amount of such Letter of Credit
(computed on the basis of the actual number of days such Letter of Credit is
outstanding in a year of 360 days). The fees described in the preceding sentence
shall be due and payable quarterly in arrears on the last Business Day of each
March, June, September and December of each year and on the Termination Date or
such earlier date as the Commitments are terminated and shall be nonrefundable.

                           (b) In addition to the foregoing fees and
commissions, the Borrower shall pay or reimburse the Issuing Bank for such
normal and customary costs and expenses as are incurred or charged by the
Issuing Bank in issuing, effecting payment under, amending or otherwise
administering any Letter of Credit.

                           (c) The Agent shall, promptly following its receipt
thereof, distribute to the Issuing Bank and the Lenders all fees and commissions
received by the Agent for their respective accounts pursuant to this subsection.

                  2.7 L/C Participations. (a) The Issuing Bank irrevocably
agrees to grant and hereby grants to each L/C Participant, and, to induce the
Issuing Bank to issue Letters of Credit hereunder, each L/C Participant
irrevocably agrees to accept and purchase and hereby accepts and purchases from
the 

                                          24

<PAGE>


Issuing Bank, on the terms and conditions hereinafter stated, for such L/C
Participant's own account and risk, an undivided interest equal to such L/C
Participant's Commitment Percentage in the Issuing Bank's obligations and rights
under each Letter of Credit issued by the Issuing Bank hereunder and the amount
of each draft paid by the Issuing Bank thereunder. Each L/C Participant
unconditionally and irrevocably agrees with the Issuing Bank that, if a draft is
paid under any Letter of Credit issued by the Issuing Bank for which the Issuing
Bank is not reimbursed in full by the Borrower in accordance with the terms of
this Agreement, such L/C Participant shall pay to the Issuing Bank upon demand
at the Issuing Bank's address for notices specified herein an amount equal to
such L/C Participant's Commitment Percentage of the amount of such draft or any
part thereof, which is not so reimbursed. Any action taken or omitted by the
Issuing Bank under or in connection with a Letter of Credit, if taken or omitted
in the absence of gross negligence or willful misconduct, shall not create for
the Issuing Bank any resulting liability to any Lender.

                           (b) If any amount required to be paid by any L/C
Participant to the Issuing Bank pursuant to subsection 2.7(a) in respect of any
unreimbursed portion of any payment made by the Issuing Bank under any Letter of
Credit is not paid to the Issuing Bank on the date such payment is due from such
L/C Participant, such L/C Participant shall pay to the Issuing Bank on demand an
amount equal to the product of (i) such amount, times (ii) the daily average
Federal Funds Effective Rate, as quoted by the Issuing Bank, during the period
from and including the date such payment is required to the date on which such
payment is immediately available to the Issuing Bank, times (iii) a fraction the
numerator of which is the number of days that elapse during such period and the
denominator of which is 360. A certificate of the Issuing Bank submitted to any
L/C Participant with respect to any amounts owing under this subsection shall be
conclusive in the absence of manifest error.

                           (c) Whenever, at any time after the Issuing Bank has
made payment under any Letter of Credit and has received from any L/C
Participant its pro rata share of such payment in accordance with subsection
2.7(a), the Issuing Bank receives any payment related to such Letter of Credit
(whether directly from the Borrower or otherwise, including by way of set-off or
proceeds of collateral applied thereto by the Issuing Bank), or any payment of
interest on account thereof, the Issuing Bank will distribute to such L/C
Participant its pro rata share thereof; provided, however, that in the event
that any such payment received by the Issuing Bank shall be required to be
returned by the Issuing Bank, such L/C Participant shall return to the 

                                        25

<PAGE>


Issuing Bank the portion thereof previously distributed by the Issuing Bank to
it.

                  2.8 Reimbursement Obligation of the Borrower. (a) The Borrower
agrees to reimburse the Issuing Bank in respect of a Letter of Credit on each
date on which a draft presented under such Letter of Credit is paid by the
Issuing Bank for the amount of (i) such draft so paid and (ii) any taxes, fees,
charges or other costs or expenses incurred by the Issuing Bank in connection
with such payment. Each such payment shall be made to the Issuing Bank at its
office listed in subsection 10.2 in U.S. Dollars and in immediately available
funds.

                           (b) Interest shall be payable on any and all amounts
remaining unpaid by the Borrower under this subsection from the date such
amounts become payable (whether at stated maturity, by acceleration or
otherwise) until payment in full at the per annum rate of the Base Rate plus
2.25% and shall be payable on demand by the Issuing Bank.

                  2.9 Obligations Absolute. (a) The obligations of the Borrower
under subsections 2.4 through 2.11 shall be absolute and unconditional under any
and all circumstances and irrespective of any set-off, counterclaim or defense
to payment which the Borrower or any Affiliate thereof may have or have had
against the Issuing Bank or any beneficiary of a Letter of Credit or any other
Person.

                           (b) The Borrower agrees with the Issuing Bank that
the Issuing Bank shall not be responsible for, and the Borrower's Reimbursement
Obligations under subsection 2.8(a) shall not be affected by, among other things
(i) the validity or genuineness of documents or of any endorsements thereon,
even though such documents shall in fact prove to be invalid, fraudulent or
forged, provided, that reliance upon such documents by the Issuing Bank shall
not have constituted gross negligence or willful misconduct of the Issuing Bank
or (ii) any dispute between or among the Borrower or any Affiliate thereof and
any beneficiary of any Letter of Credit or any other party to which such Letter
of Credit may be transferred or (iii) any claims whatsoever of the Borrower or
any Affiliate thereof against any beneficiary of such Letter of Credit or any
such transferee.

                           (c) The Issuing Bank shall not be liable for any
error, omission, interruption or delay in transmission, dispatch or delivery of
any message or advice, however transmitted, in connection with any Letter of
Credit, except for errors or omissions caused by the Issuing Bank's gross
negligence or willful misconduct.

                                        26

<PAGE>


                           (d) The Borrower agrees that any action taken or
omitted by the Issuing Bank under or in connection with any Letter of Credit or
the related drafts or documents, if done in the absence of gross negligence or
willful misconduct, shall be binding on the Borrower and shall not result in any
liability of the Issuing Bank to the Borrower.

                  2.10 Letter of Credit Payments. If any draft shall be
presented for payment to the Issuing Bank under any Letter of Credit, the
Issuing Bank shall promptly notify the Borrower of the date and amount thereof.
The responsibility of the Issuing Bank to the Borrower in connection with any
draft presented for payment under any Letter of Credit shall, in addition to any
payment obligation expressly provided for in such Letter of Credit and any other
obligation expressly imposed by the Uniform Customs, be limited to determining
that the documents (including each draft) delivered under such Letter of Credit
in connection with such presentment are in conformity with such Letter of
Credit.

                  2.11 Application. To the extent that any provision of any
Application related to any Letter of Credit is inconsistent with the provisions
of this Agreement, the provisions of this Agreement shall apply.


                SECTION 3. GENERAL PROVISIONS APPLICABLE TO LOANS

                                       27

<PAGE>


                  3.1 Fees. (a) The Borrower agrees to pay to the Agent for the
account of each Lender, on each March 31, June 30, September 30 and December 31
during the Commitment Period and on the date on which the Commitments shall be
terminated as provided herein, a commitment fee (the "Commitment Fee") at a rate
per annum equal to .20% on the average daily amount of the Available Commitments
during the preceding quarter (or shorter period commencing with the date hereof
or ending with the Termination Date or the date on which the Commitments shall
be terminated). All Commitment Fees shall be computed on the basis of the actual
number of days elapsed in a year of 360 days and shall be paid in Dollars. The
Commitment Fee due to each Lender shall commence to accrue on the date hereof,
and shall cease to accrue on the earlier of the Termination Date and the
termination of the Commitment of such Lender as provided herein. The Agent shall
distribute the Commitment Fees on the Available Commitments among the Lenders
pro rata in accordance with their respective Commitment Percentages.

                           (b) The foregoing fees shall be paid on the dates
due, in immediately available funds, to the Agent for distribution, if and as
appropriate, among the Lenders. Once paid, none of the foregoing fees shall be
refundable under any circumstances.

                  3.2 Interest Rates and Payment Dates. (a) Subject to the
provisions of subsection 3.3, each Base Rate Loan shall bear interest (computed
on the basis of the actual number of days elapsed over a year of 365 or 366
days, as the case may be) at a rate per annum equal to the Base Rate plus the
Applicable Margin.

                           (b) Subject to the provisions of subsection 3.3, each
Eurodollar Loan shall bear interest (computed on the basis of the actual number
of days elapsed over a year of 360 days) at a rate per annum equal to the
Euro-Rate for the Interest Period in effect for such Eurodollar Loan plus the
Applicable Margin.

                           (c) Interest on each Loan shall be payable in arrears
on each Interest Payment Date applicable to such Loan; provided that, interest
accruing on overdue amounts pursuant to subsection 3.3 shall be payable on
demand as provided in such subsection.

                           (d) As soon as practicable the Agent shall notify the
Borrower and the Lenders of (i) each determination of a Euro-Rate and (ii) the
effective date and the amount of each change in 

                                      28

<PAGE>


the interest rate on a Eurodollar Loan or Base Rate Loan. Each determination of
an interest rate by the Agent pursuant to any provision of this Agreement
(including this subsection 3.2 and subsection 3.3) shall be conclusive and
binding on the Borrower and the Lenders in the absence of clearly demonstrable
error. At the request of the Borrower, the Agent shall deliver to the Borrower a
statement showing the quotations used by it in determining any interest rate
pursuant to subsections 3.2(a) through 3.2(c).

                  3.3 Default Interest. If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, the Borrower shall on demand from time to time pay interest on
any overdue payment of principal (in lieu of the interest otherwise payable on
such principal under Section 3.2) and, to the extent permitted by law, on
overdue payments of interest and other amounts due hereunder up to the date of
actual payment (after as well as before judgment):

                           (a) in the case of overdue principal of a Loan, at a
rate determined by the Agent to be the lower of (i) 2% per annum above the rate
which would otherwise be payable on such Loan in accordance with the provisions
hereof or (ii) the maximum rate permitted under applicable law;

                           (b) in the case of any other amount payable hereunder
(whether for interest, fees or otherwise), at a rate equal to 2.25% per annum
above the Base Rate.

                  3.4 Inability to Determine Interest Rate. In the event, and on
each occasion, that prior to the first day of the commencement of any Interest
Period for a Eurodollar Loan, the Agent shall have determined (which
determination shall be conclusive and binding upon the Borrower) that dollar
deposits in the principal amount of such Eurodollar Loan are not generally
available in the London interbank market, or that the rate at which such dollar
deposits are being offered will not adequately and fairly reflect the cost to
the Lenders of making or maintaining the principal amount of such Eurodollar
Loan during such Interest Period, or that reasonable means do not exist for
ascertaining the Euro-Rate, the Agent shall, as soon as practicable thereafter,
give written, telegraphic or telephonic notice of such determination to the
Borrower and the Lenders. After such notice shall have been given and until the
circumstances giving rise to such notice no longer exist, each request for a
Eurodollar Loan or for conversion to or maintenance of a Eurodollar Loan
pursuant to the terms of this Agreement shall be deemed to be a request for a
Base Rate Loan. Each determination by the Agent hereunder shall be conclusive
absent 

                                        29

<PAGE>


error in calculation or other manifest error.

                  3.5 Termination, Reduction and Extension of Commitments. (a)
The Commitments shall be automatically terminated on the Termination Date,
whereupon the entire outstanding principal balance of the Loans, plus all
accrued and unpaid interest thereon, and any fees or other amounts owed under
the Loan Documents, shall become due and payable.

                           (b) Upon at least three Business Days' prior
irrevocable written (including telecopy) notice to the Agent, the Borrower may
at any time in whole permanently terminate, or from time to time in part
permanently reduce, the Commitments; provided, however, that (i) each partial
reduction of any Commitment shall be in a minimum principal amount of $5,000,000
or in whole multiples of $1,000,000 in excess thereof, and (ii) the Commitments
may not be reduced or terminated if, after giving effect thereto and to any
prepayments of the Loans made on the effective date thereof, the aggregate
amount of the Exposure at such time would exceed the aggregate amount of the
Commitments at such time.

                           (c) Any prepayment of the Loans pursuant to
subsection 3.7(a) shall permanently reduce the Commitments on a
dollar-for-dollar basis.

                           (d) Each reduction in the Commitments hereunder shall
be made ratably among the Lenders in accordance with their respective Commitment
Percentages. The Borrower shall pay to the Agent for the account of the Lenders
on the date of each termination or reduction of the Commitments, the Commitment
Fees on the amount of the Commitments so terminated or reduced accrued to the
date of such termination or reduction.

                           (e) During the period beginning sixty days prior to
the first and any subsequent anniversary of the Closing Date and ending on such
anniversary, the Borrower may deliver to the Agent (which shall promptly
transmit to each Lender) a notice requesting that the Commitments be extended to
the first anniversary of the Termination Date then in effect. Within 45 days
after its receipt of any such notice, each Lender shall notify the Agent of its
willingness or unwillingness so to extend its Commitment. Any Lender that shall
fail so to notify the Agent within such period shall be deemed to have declined
to extend its Commitment. If all of the Lenders agree to extend their
Commitments, the Agent shall so notify the Borrower and each Lender, whereupon
(i) the respective Commitments of the 

                                        30

<PAGE>


Lenders shall without further act be extended to the first anniversary of the
Termination Date then in effect and (ii) the term "Termination Date" shall
thereafter mean such first anniversary. Any such extension shall be evidenced by
a written agreement among the Agent, the Lenders and the Borrower, such
agreement to be in form and substance acceptable to the Agent, the Lenders and
the Borrower.

                  3.6 Optional Prepayment of Loans. (a) The Borrower shall have
the right at any time and from time to time to prepay any Loan, in whole or in
part, without premium or penalty (but in any event subject to subsection 3.11),
upon prior written, telecopy or telephonic notice to the Agent in the case of
Base Rate Loans no later than 10:30 a.m., Philadelphia time, one Business Day
before any proposed prepayment, and in the case of Eurodollar Loans, no later
than 10:30 a.m., Philadelphia time, three Business Days before any such proposed
prepayment. In each case the notice shall specify the date and amount of each
such prepayment, whether the prepayment is of Eurodollar Loans or Base Rate
Loans or a combination thereof, and, if a combination thereof, the amount
allocable to each; provided, however, that each such partial prepayment shall be
in the principal amount of at least $5,000,000 or in whole multiples of
$1,000,000 in excess thereof.

                           (b) On the date of any termination or reduction of
the Commitments pursuant to subsection 3.5, the Borrower shall pay or prepay so
much of the Loans as shall be necessary in order that the sum of the aggregate
amount of the Exposure at such time would not exceed the aggregate amount of the
Commitments at such time as so reduced.

                           (c) Each notice of prepayment shall be irrevocable
and shall commit the Borrower to prepay the amount specified in such notice.

                           (d) Upon receipt of any notice of prepayment, the
Agent shall promptly notify each Lender thereof.

                           (e) Amounts prepaid pursuant to subsection 3.6(a) on
account of the Loans may be reborrowed, subject to the terms and conditions
hereof.

                  3.7 Mandatory Prepayments. (a) Simultaneously with any Asset
Sale, the Borrower shall pay (or cause to be paid) to the Agent an amount equal
to the Net Proceeds of such Asset Sale; provided that, if at the time of an
Asset Sale no Default or Event of Default exists, no payment should be required
pursuant to this clause (a) to the extent that the Borrower intends in good
faith to apply such Net Proceeds to the acquisition of 

                                      31

<PAGE>


income producing related assets within six (6) months after the date of such
Asset Sale; provided further, that such Net Proceeds shall be paid to the Agent
at the end of such six-month period to the extent that the Borrower has not by
the end of such period utilized such Net Proceeds to purchase substitute income
producing related assets; provided, further, that, in each fiscal year of the
Borrower, the Borrower shall not be required (unless a Default or Event of
Default shall exist hereunder) to make any prepayments pursuant to this clause
(a) until the Net Proceeds from Assets Sales in such fiscal year otherwise
payable hereunder shall exceed $250,000, whereupon the amount of Net Proceeds
that must be applied to the Loans pursuant to this subsection shall equal 100%
of all Net Proceeds in such fiscal year other than those Net Proceeds not
payable hereunder pursuant to the first proviso to this sentence. Any payments
made to the Agent pursuant to this subsection 3.7(a) shall be applied by the
Agent to the principal amount of the Loans and shall reduce the aggregate
Commitments on a dollar-for-dollar basis. The Borrower shall give the Agent at
least one Business Day's prior written notice of each prepayment pursuant to
this subsection 3.7(a) setting forth the date and expected amount thereof.

                           (b) All prepayments under this subsection 3.7 shall,
to the extent possible, be applied first to any Base Rate Loans then outstanding
and the balance, if any, to Eurodollar Loans then outstanding, with payments
applied to Eurodollar Loans being applied in order of next maturing Interest
Periods. Any prepayment of Eurodollar Loans shall be subject to subsection 3.11.

                  3.8 Illegality. Notwithstanding any other provision herein, if
any change in any Requirement of Law or in the interpretation or application
thereof shall make it unlawful for any Lender to make or maintain Eurodollar
Loans as contemplated by this Agreement, (a) the commitment of such Lender
hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
refinance Base Rate Loans to Eurodollar Loans shall forthwith be cancelled and
(b) such Lender's Loans then outstanding as Eurodollar Loans, if any, shall be
converted automatically to Base Rate Loans on the respective last days of the
then current Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to such Lender such amounts, if any, as may be
required pursuant to subsection 3.11.

                  3.9 Requirements of Law. (a) In the event that any change in
any Requirement of Law or in the interpretation, or application thereof or
compliance by any Lender with any request 

                                      32

<PAGE>


or directive (whether or not having the force of law) from any central bank or
other Governmental Authority made subsequent to the date hereof:

                                    (i) shall subject any Lender to any tax of
         any kind whatsoever with respect to this Agreement, any Note, any
         Letter of Credit, any Application, or any Eurodollar Loan made by it,
         or change the basis of taxation of payments to such Lender in respect
         thereof (except for taxes covered by subsection 3.10 and changes in the
         rate of tax on the net income of such Lender);

                                    (ii) shall impose, modify or hold applicable
         any reserve, special deposit, compulsory loan or similar requirement
         against assets held by, deposits or other liabilities in or for the
         account of, advances, loans or other extensions of credit by, or any
         other acquisition of funds by, any office of such Lender which is not
         otherwise included in the determination of the interest rate on such
         Eurodollar Loan, hereunder; or

                                    (iii) shall impose on such Lender any other
         condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or issuing or participating in
Letters of Credit or maintaining any Commitment hereunder or to reduce any
amount receivable hereunder in respect thereof then, in any such case, the
Borrower shall as promptly as practicable pay such Lender, upon its demand, any
additional amounts necessary to compensate such Lender for such increased cost
or reduced amount receivable. If any Lender becomes entitled to claim any
additional amounts pursuant to this subsection, it shall as promptly as
practicable notify the Borrower, through the Agent, of the event by reason of
which it has become so entitled. A certificate as to any additional amounts
payable pursuant to this subsection submitted by such Lender, through the Agent,
to the Borrower shall be conclusive in the absence of clearly demonstrable
error. This covenant shall survive the termination of this Agreement and the
payment of the Loans and all other amounts payable hereunder.

                           (b) In the event that any Lender shall have
determined that any change in any Requirement of Law regarding capital adequacy
or in the interpretation or application thereof or compliance by such Lender or
any corporation controlling such 

                                     33

<PAGE>


Lender with any request or directive regarding capital adequacy (whether or not
having the force of law) from any Governmental Authority made subsequent to the
date hereof does or shall have the effect of reducing the rate of return on such
Lender's or such corporation's capital as a consequence of its obligations
hereunder or under any Letter of Credit to a level below that which such Lender
or such corporation could have achieved but for such change or compliance
(taking into consideration such Lender's or such corporation's policies with
respect to capital adequacy) by an amount deemed by such Lender to be material,
then from time to time, the Borrower shall as promptly as practicable pay such
Lender, upon its demand, such additional amount or amounts as will compensate
such Lender for such reduction. If any Lender becomes entitled to claim any
additional amounts pursuant to this subsection, it shall as promptly as
practicable notify the Borrower, through the Agent, of the event by reason of
which it has become so entitled. A certificate as to any additional amounts
payable pursuant to this subsection submitted by such Lender, through the Agent,
to the Borrower shall be conclusive in the absence of clearly demonstrable
error. This covenant shall survive the termination of this Agreement and the
payment of the Loans and all other amounts payable hereunder.

                           (c) Each Lender agrees that it will use reasonable
efforts in order to avoid or to minimize, as the case may be, the payment by the
Borrower of any additional amount under subsections 3.9(a) or (b); provided,
however, that no Lender shall be obligated to incur any expense, cost or other
amount (other than insignificant incidental expenses or costs) in connection
with utilizing such reasonable efforts.

                  3.10 Taxes. (a) All payments made by the Borrower under this
Agreement and the Notes shall be made free and clear of, and without deduction
or withholding for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or withholdings,
now or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority (excluding, in the case of the Agent and each Lender, net
income taxes and franchise or gross receipts taxes imposed on the Agent or such
Lender, as the case may be, as a result of a present or former connection
between the jurisdiction of the government or taxing authority imposing such tax
and the Agent or such Lender (excluding a connection arising solely from the
Agent or such Lender having executed, delivered or performed its obligations or
received a payment under, or enforced, this Agreement or the Notes)) (all such
non-excluded taxes, levies, imposts, duties, charges, fees, deductions and
withholdings being hereinafter called "Taxes"). If any Taxes are required to be
withheld from any amounts payable to the Agent or any Lender hereunder or under
the Notes, the amounts so payable 

                                         34

<PAGE>


to the Agent or such Lender shall be increased to the extent necessary to yield
to the Agent or such Lender (after payment of all Taxes) interest or any such
other amounts payable hereunder at the rates or in the amounts specified in this
Agreement and the Notes. Whenever any Taxes are payable by the Borrower, as
promptly as possible thereafter the Borrower shall send to the Agent for its own
account or for the account of such Lender, as the case may be, a certified copy
of an original official receipt received by the Borrower showing payment
thereof. If the Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Agent the required receipts or other
required documentary evidence, the Borrower shall indemnify the Agent and the
Lenders for any incremental taxes, interest or penalties that may become payable
by the Agent or any Lender as a result of any such failure. The agreements in
this subsection shall survive the termination of this Agreement and the payment
of the Loans and all other amounts payable hereunder.

                           (b) Each Lender that is not incorporated under the
laws of the United States of America or a state thereof agrees that it will
deliver to the Borrower and the Agent (i) two duly completed copies of United
States Internal Revenue Service Form 1001 or 4224 or successor applicable form,
as the case may be, and (ii) an Internal Revenue Service Form W-8 or W-9 or
successor applicable form, or such other properly completed documentation
prescribed by applicable law, as will permit payments hereunder to be made
without withholding or at a reduced rate. Each such Lender also agrees to
deliver to the Borrower and the Agent two further copies of the said Form 1001
or 4224 and Form W-8 or W-9, or successor applicable forms or other manner of
certification, as the case may be, or such other properly completed
documentation prescribed by applicable law, as will permit payments hereunder to
be made without withholding or at a reduced rate, on or before the date that any
such form expires or becomes obsolete or after the occurrence of any event
requiring a change in the most recent form previously delivered by it to the
Borrower, and such extensions or renewals thereof as may reasonably be requested
by the Borrower or the Agent, unless in any such case an event (including,
without limitation, any change in treaty, law or regulation) has occurred prior
to the date on which any such delivery would otherwise be required which renders
all such forms inapplicable or which would prevent such Lender from duly
completing and delivering any such form with respect to it and such Lender so
advises the Borrower and the Agent. Each such Lender shall certify (i) in the
case of a Form 1001 or 4224, that it is entitled to receive payments under this

                                         35


<PAGE>


Agreement without deduction or withholding of any United States federal income
taxes and (ii) in the case of a Form W-8 or W-9, that it is entitled to an
exemption from United States backup withholding tax.

                           (c) Notwithstanding the foregoing subsections 3.10(a)
or 3.10(b), the Borrower shall not be required to pay any additional amounts to
any Lender in respect of United States withholding tax pursuant to such
subsections if (i) the obligation to pay such additional amounts would not have
arisen but for a failure by such Lender to comply with the requirements of
subsection 3.10(b) or (ii) such Lender shall not have furnished the Borrower
with such forms listed in subsection 3.10(b) and shall not have taken such other
steps as reasonably may be available to it under applicable tax laws and any
applicable tax treaty or convention to obtain an exemption from, or reduction
(to the lowest applicable rate) of, such United States withholding tax.

                  3.11 Indemnity. (a) The Borrower agrees to indemnify each
Lender and to hold each Lender harmless from any loss or expense which such
Lender may sustain or incur as a consequence of (i) default by the Borrower in
payment when due of the principal amount of or interest on any Eurodollar Loan,
(ii) default by the Borrower in making a borrowing of, conversion into or
continuation of Eurodollar Loans, after the Borrower has given a notice
requesting the same in accordance with the provisions of this Agreement, (iii)
default by the Borrower in making any prepayment after the Borrower has given a
notice thereof in accordance with the provisions of this Agreement or (iv) the
making of a prepayment (whether voluntary, mandatory, as a result of
acceleration or otherwise) of Eurodollar Loans on a day which is not the last
day of an Interest Period with respect thereto, including, without limitation,
any such loss or expense arising from the reemployment of funds obtained by it
or from fees payable to terminate the deposits from which such funds were
obtained. A certificate as to any amounts that a Lender is entitled to receive
under this subsection 3.11 submitted by such Lender, through the Agent, to the
Borrower shall be conclusive in the absence of clearly demonstrable error and
all such amounts shall be paid by the Borrower promptly upon demand by such
Lender. This covenant shall survive the termination of this Agreement and the
payment of the Loans and all other amounts payable hereunder.

                           (b) For the purpose of calculation of all amounts
payable to a Lender under this subsection, each Lender shall be deemed to have
actually funded its relevant Eurodollar Loan, through the purchase of a deposit
bearing interest at the Euro-Rate, in an amount equal to the amount of that
Eurodollar Loan, 

                                       36

<PAGE>


and having a maturity comparable to the relevant Interest Period or due date;
provided, however, that each Lender may fund each of its Eurodollar Loans in any
manner it sees fit, and the foregoing assumptions 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 Loans and all
other amounts payable hereunder.

                  3.12 Pro Rata Treatment of Loans, L/C's and Payments;
Commitment Fees. (a) Except as required under subsection 3.8, each borrowing of
Loans, each payment or prepayment of principal of any Loans, each payment of
interest on the Loans, each payment of Commitment Fees with respect to the
Commitments, and each reduction of the Commitments, shall be made pro rata among
the Lenders in accordance with their respective Commitment Percentages.

                           (b) Each Lender agrees that in computing such
Lender's portion of any borrowing to be made hereunder, the Agent may, in its
discretion, round each Lender's percentage of such borrowing to the next higher
or lower whole dollar amount.

                           (c) Unless the Agent shall have been notified in
writing by the Borrower prior to the date of any payment being made hereunder
that the Borrower will not make such payment to the Agent, the Agent may assume
that the Borrower will make such payment, and the Agent may, but shall not be
required to, in reliance upon such assumption, make available to the Lenders
their respective pro rata shares of the corresponding amount. If such payment is
not made to the Agent by the Borrower, the Agent shall be entitled to recover,
on demand, from each Lender to which any amount was made available pursuant to
the preceding sentence, the amount so made available with interest thereon from
the date that the Agent made such amount available to such Lender(s)at the rate
per annum equal to the daily average Federal Funds Effective Rate. Nothing
herein shall be deemed to limit the rights of the Agent or any Lender against
the Borrower.

                  3.13 Payments. (a) The Borrower shall make each payment
(including principal of or interest on any borrowing or any fees or other
amounts including Reimbursement Obligations) hereunder not later than 12:00
(noon), Philadelphia time, on the date when due in Dollars to the Agent at its
office set forth in subsection 10.2, in immediately available funds. Such
payments shall be made without set off or counterclaim of any kind. The Agent
shall distribute to the Lenders or the Issuing Bank any payments received by the
Agent on their behalf promptly upon receipt in like funds as received.

                           (b) Whenever any payment (including principal of 

                                      37

<PAGE>


or interest on any borrowing or any fees or other amounts) hereunder (other than
payments on Eurodollar Loans) shall become due, or otherwise would occur, on a
day that is not a Business Day, such payment may be made on the next succeeding
Business Day, and such extension of time shall in such case be included in the
computation of interest or fees, if applicable.

                  3.14 Conversion and Continuation Options. The Borrower shall
have the right at any time upon prior irrevocable notice to the Agent (i) not
later than 12:00 noon, Philadelphia time, one Business Day prior to conversion,
to convert any Eurodollar Loan to a Base Rate Loan, (ii) not later than 10:00
a.m., Philadelphia time, three Business Days prior to conversion or
continuation, to convert any Base Rate Loan into a Eurodollar Loan or to
continue any Eurodollar Loan as a Eurodollar Loan for any additional Interest
Period, (iii) not later than 10:00 a.m., Philadelphia time, three Business Days
prior to conversion, to convert the Interest Period with respect to any
Eurodollar Loan to another permissible Interest Period subject in each case to
the following:

                           (a) a Eurodollar Loan may not be converted at a time
other than the last day of the Interest Period applicable thereto;

                           (b) any portion of a Loan required to be repaid in
less than one month or maturing within one month of the Termination Date may not
be converted into or continued as a Eurodollar Loan;

                           (c) no Eurodollar Loan may be continued as such and
no Base Rate Loan may be converted to a Eurodollar Loan when any Default has
occurred and is continuing and the Agent or the Required Lenders have determined
that such a continuation is not appropriate;

                           (d) any portion of a Eurodollar Loan that cannot be
converted into or continued as a Eurodollar Loan by reason of paragraph 3.14(b)
or 3.14(c) automatically shall be converted at the end of the Interest Period in
effect for such Loan to a Base Rate Loan;

                           (e) on the last day of any Interest Period for
Eurodollar Loans, if the Borrower has failed to give notice of conversion or
continuation as described in this subsection or if such conversion or
continuation is not permitted pursuant to subsection 3.14(d), such Loans shall
be converted to Base Rate 

                                        38

<PAGE>


Loans on the last day of such then expiring Interest Period;

                           (f) Each request by the Borrower to convert or
continue a Loan shall constitute a representation and warranty that no Default
shall have occurred and be continuing.

Accrued interest on a Loan (or portion thereof) being converted shall be paid by
the Borrower at the time of conversion.

                  3.15 Minimum Amounts of Tranches; Maximum Number of Tranches.
(a) All borrowings, conversions and continuation of Loans hereunder and all
selections of Interest Periods hereunder shall be in such amounts and be made
pursuant to such elections that, after giving effect thereto, the aggregate
principal amount of the Loans comprising each Tranche of Eurodollar Loans shall
be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof.

                       (b) The Borrower shall not have outstanding at any one
time more than in the aggregate five Tranches of Eurodollar Loans.

                  3.16 Use of Proceeds. The proceeds of the Loans shall be used
by the Borrower for working capital and general corporate purposes (including
the TASG Acquisition and other acquisitions to the extent permitted hereunder).


                    SECTION 4. REPRESENTATIONS AND WARRANTIES

                  To induce the Agent and the Lenders to enter into this
Agreement and to make the Loans and to issue or participate in the Letters of
Credit, the Borrower hereby represents and warrants to the Agent and each Lender
that:

                  4.1 Financial Condition. The consolidated balance sheet of 
the Borrower and its consolidated Subsidiaries as at December 31, 1997 and 
the related consolidated statements of income and of cash flows for the 
fiscal year ended on such date, copies of which have heretofore been 
furnished to each Lender, present fairly the consolidated financial condition 
of the Borrower and its consolidated Subsidiaries as at such date, and the 
consolidated results of their operations and their consolidated cash flows 
for the fiscal year then ended. The unaudited consolidated balance sheet of 
the Borrower and its consolidated Subsidiaries as at June 30, 1998 and the 
related unaudited consolidated statements of income and of cash flows for the 
six-month period ended on such date, certified by a Responsible Officer of 
the Borrower, copies of which have heretofore been furnished to each Lender, 
present fairly the


                                     39

<PAGE>

consolidated financial condition of the Borrower and its consolidated 
Subsidiaries as at such date, and the consolidated results of their 
operations and their consolidated cash flows for the six-month period then 
ended (subject to normal year-end audit adjustments). All such financial 
statements, including the related schedules and notes thereto, have been 
prepared in accordance with GAAP applied consistently throughout the periods 
involved. Neither the Borrower nor any of its consolidated Subsidiaries had, 
at the date of the most recent balance sheet referred to above, any material 
Guarantee Obligation, liability for taxes, or any long-term lease or unusual 
forward or long-term commitment, including, without limitation, any interest 
rate or foreign currency swap or exchange transaction, which is required by 
GAAP to be but is not reflected in the foregoing statements or in the notes 
thereto.

                  4.2 No Change. Since December 31, 1997, there has been no
development or event nor prospective development or event which has had or could
reasonably be expected to have a Material Adverse Effect.

                  4.3 Corporate Existence; Compliance with Law. Each of the Loan
Parties and its Subsidiaries (a) is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, (b) has the
corporate power and authority, and the legal right, to own and operate its
property, to lease the property it operates as lessee and to conduct the
business in which it is currently engaged, (c) is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business
requires such qualification, except to the extent that the failure to be so
qualified could not, in the aggregate, reasonably be expected to have a Material
Adverse Effect and (d) is in compliance with all Requirements of Law except to
the extent that the failure to comply therewith could not, in the aggregate,
reasonably be expected to have a Material Adverse Effect.

                  4.4 Corporate Power; Authorization; Enforceable Obligations.
Each of the Loan Parties has the corporate power, authority, and legal right, to
make, deliver and perform this Agreement and each other Loan Document to which
it is a party and, in the case of the Borrower, to borrow hereunder (including
through the issuance of Letters of Credit) and has taken all necessary corporate
action (a) in the case of the Borrower, to authorize the borrowings (including
the Letters of Credit) on the terms and conditions of this Agreement and each
other Loan 

                                        40

<PAGE>


Document to which it is a party, and (b) in the case of each of the Loan
Parties, to authorize the execution, delivery and performance of this Agreement
and each other Loan Document to which it is a party. No consent or authorization
of, filing with or other act by or in respect of, any Governmental Authority or
any other Person (including stockholders and creditors of the Loan Parties) is
required in connection with the Extensions of Credit hereunder or with the
execution, delivery, performance, validity or enforceability of this Agreement
or any other Loan Document. This Agreement has been and each other Loan Document
to which it is a party will be, duly executed and delivered on behalf of such
Loan Party. This Agreement constitutes and each other Loan Document when
executed and delivered will constitute, a legal, valid and binding obligation of
each Loan Party party thereto enforceable against such Loan Parties in
accordance with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles
(whether enforcement is sought by proceedings in equity or at law).

                  4.5 No Legal Bar. The execution, delivery and performance of
this Agreement, the Notes and the other Loan Documents by the Loan Parties, the
Extensions of Credit hereunder and the use of the proceeds thereof will not
violate any Requirement of Law or Contractual Obligation of any Loan Party or
any of its Subsidiaries and will not result in, or require, the creation or
imposition of any Lien on any properties or revenues of any Loan Party pursuant
to any such Requirement of Law or Contractual Obligation.

                  4.6 No Material Litigation. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Borrower, threatened against any Loan Party or any of
their respective Subsidiaries or against any of its or their respective
properties or revenues (a) with respect to this Agreement, the Notes, the other
Loan Documents or any of the transactions contemplated hereby, or (b) as to
which there is a reasonable likelihood of an adverse determination and which, if
adversely determined, could have a Material Adverse Effect.

                  4.7 No Default. Neither the Borrower, any other Loan Party nor
any of its or their Subsidiaries is in default under or with respect to any of
its Contractual Obligations in any respect which could have a Material Adverse
Effect. No Default or Event of Default has occurred and is continuing.

                  4.8 Taxes. Each of the Loan Parties has filed or caused to be
filed all tax returns which, to its knowledge, are 

                                     41

<PAGE>


required to be filed and has paid all taxes shown to be due and payable on said
returns or on any assessments made against it or any of its property and all
other taxes, fees or other charges imposed on it or any of its property by any
Governmental Authority (other than any the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which reserves, if any, in conformity with GAAP have been provided on
the books of the Borrower or its Subsidiaries, as the case may be); no tax Lien
has been filed against any of the Loan Parties or any of their Subsidiaries,
and, to the knowledge of each of the Loan Parties, no claim is being asserted,
with respect to any such tax, fee or other charges.

                  4.9 Federal Regulations. No part of the proceeds of any Loans
will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U or for any
purpose which violates the provisions of Regulation U or any other Regulations
of the Board of Governors of the Federal Reserve System. If requested by any
Lender or the Agent, the Borrower will furnish to the Agent and each Lender a
statement to the foregoing effect in conformity with the requirements of FR Form
G-3 or FR Form U-l referred to in said Regulation U. No part of the proceeds of

funding deficiency" (within the meaning of Section 412 of the Code or Section

each Single Employer Plan in which the Borrower or any Commonly Controlled
Entity is a participant (based on those assumptions used to fund the Plans) did
not, as of the last annual valuation date prior to the date on which this
representation is made or deemed made, exceed the value of the assets of such
Plan allocable to such accrued benefits by an amount in excess of five percent
(5%) of Consolidated Net Worth as of the end of the most recent fiscal year of
the Borrower for 

                                       42

which financial statements have been delivered to the Lenders pursuant to this
Agreement.

                           (c) Neither the Borrower nor any Commonly Controlled
Entity has had a complete or partial withdrawal from any Multiemployer Plan, and
neither the Borrower nor any Commonly Controlled Entity would become subject to
any liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made.

                           (d) No such Multiemployer Plan is in "reorganization"

                           (e) The present value (determined using actuarial and
other assumptions which are reasonable in respect of the benefits provided and
the employees participating) of the liability of the Borrower and each Commonly
Controlled Entity for post retirement benefits to be provided to their current
and former employees under Plans which are welfare benefit plans (as defined in
Section 3(1) of ERISA) does not, in the aggregate, exceed the assets under all
such Plans allocable to such benefits by an amount in excess of five percent
(5%) of Consolidated Net Worth as of the end of the most recent fiscal year of
the Borrower for which financial statements have been delivered to the Lenders
pursuant to this Agreement.

by the Borrower only for the purposes permitted by subsection 3.16

                  4.13 Environmental Matters. Except to the extent that all of

$1,000,000:

                           (a) The Properties do not contain, and have not

at the Properties are in compliance, and have in the last five years been in

or about the Properties or violation of any Environmental Law with respect to
the Properties or the business operated by any Loan Party or any Subsidiary
thereof which could interfere with the continued operation of any of the
Properties or impair the fair saleable value of any thereof. None of the Loan
Parties or any of their respective Subsidiaries have assumed any liability of
any Person under Environmental Laws.

                           (c) Neither the Borrower, any other Loan Party, nor
any of their Subsidiaries has received or is aware of any claim, notice of

satisfactorily resolved by the Borrower, such other Loan Party, or such
Subsidiary, nor is the Borrower nor any other Loan Party aware or have reason to
believe that any such action is being contemplated, considered or threatened.

                           (d) Materials of Environmental Concern have not been
generated, treated, stored, transported, disposed of, at, on, from or under any
of the Properties, nor have any Materials of Environmental Concern been
transferred from the Properties to any other location except in either case in
the ordinary course of business of the Loan Parties or any of their respective
Subsidiaries, in compliance with all Environmental Laws and such that it could
not reasonably be expected to give rise to liability under any applicable
Environmental Law.

                           (e) There are no governmental, administrative actions
or judicial proceedings pending or, to the best knowledge of the Borrower after
reasonable inquiry, contemplated or threatened under any Environmental Laws to
which the Borrower, any other Loan Party or any of their respective Subsidiaries
is or will be named as a party with respect to the Properties, nor are there any
consent decrees or other decrees, consent orders, administrative orders or other
orders, or other administrative or judicial requirements outstanding under any
Environmental Law with respect to any of the Properties.

                           (f) There has been no release or threat of release of
Materials of Environmental Concern at or from the Properties, or arising from or
related to the operation of the Borrower or any Subsidiary in connection with
the Properties or 

                                       44

<PAGE>


otherwise in connection with the business operated by the Borrower or any

forth in paragraphs 4.13(a) through (g)is true and correct with respect to each
Property.

                  4.14 No Material Misstatements. No financial statement,
exhibit or schedule furnished by or on behalf of any Loan Party to the Agent or
any Lender in connection with the negotiation of this Agreement or any other
Loan Document contains any misstatement of fact, or omitted or omits to state
any fact necessary to make the statements therein, when read in the aggregate
with all other information so provided by the Loan Parties, not misleading under
the circumstances under which they were made or given, where such misstatement
or omission would be material to the interests of the Lenders with respect to
the performance of a Loan Party of its obligations hereunder or thereunder.
Prior to the date hereof, the Borrower has disclosed to the Lenders in writing
any and all facts which materially and adversely affect (to the extent the
Borrower can as of the date hereof reasonably foresee), the business, operations
or financial condition of the Borrower and its Subsidiaries taken as a whole,
and the ability of the Loan Parties to perform their obligations under this
Agreement and the other Loan Documents.

                  4.15 Intellectual Property. Each of the Loan Parties and each
of their respective Subsidiaries owns, or is licensed to use, all trademarks,
tradenames, copyrights, technology, know-how and processes necessary for the
conduct of its business as currently conducted (the "Intellectual Property")
except for those as to which the failure to own or license could not reasonably
be expected to have a Material Adverse Effect. No claim has been asserted and is
pending by any Person challenging or questioning the use of any such
Intellectual Property, nor does such Loan Party know of any valid basis for any
such claim. The use of such Intellectual Property by the Loan Parties and their
Subsidiaries does not infringe the rights of any Person, except for such claims
and infringements that, in the aggregate, do not have such a Material Adverse
Effect.

                  4.16 Subsidiaries. All of the Subsidiaries of the Borrower at
the date hereof are listed on Schedule 4.16 of this Agreement.

company" of a "holding company", in each case under the Public Utility Holding
Company Act of 1935, as amended.

which could be adversely affected by, and have developed or are developing a
program to address on a timely basis, the risk that certain computer
applications, as well as embedded microchips in noncomputing devices, used by
the Loan Parties or their Subsidiaries (or any of their respective material
suppliers, customers or vendors) may be unable to recognize and perform properly
date-sensitive functions involving dates prior to and after December 31, 1999

Subsidiaries has good and marketable title to, or valid leasehold interests in,
all its material real property, except for minor defects in title that do not
interfere in any material respect with its ability to conduct its business as
presently conducted. All such material properties are free and clear of all
Liens, other than Liens permitted by subsection 7.2.

                  4.20 No Burdensome Restrictions. No Requirement of Law or

authority under the laws of its jurisdiction of incorporation and under its
articles of incorporation and by-laws to enter into and perform the TASG
Acquisition Agreements; all actions (corporate or otherwise) necessary for the
execution and performance of the TASG Acquisition Agreements by the Borrower
have been taken; and the TASG Acquisition Agreements constitute the valid and
binding obligation of each party thereto, enforceable in accordance with their
respective terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles
(whether enforcement is sought by proceedings in equity or at law).

                                        46

<PAGE>


                           (c) No Violations. The making and performance of the
TASG Acquisition Agreements will not violate any provision of any law or
regulation, federal, state or local, including precedents of the jurisdiction of
incorporation of the Borrower, and will not violate any provisions of the
articles of incorporation and by-laws of the Borrower, or constitute a default
under any agreement by which the Borrower or its property may be bound.

                           (d) Immediately after the consummation of the TASG
Acquisition, the representations and warranties set forth in this Article IV
shall be true and correct in all material respects.

                  4.22 Solvency. Each of the Loan Parties is, and after receipt
and application of the first loan hereunder will be, solvent such that: (a) the
fair value of its assets (including without imitation the fair salable value of
the goodwill and other intangible property of such Loan Party) is greater than
the total amount of its liabilities, including without limitation, Guarantee
Obligations, (b) the present fair salable value of its assets (including without
limitation the fair salable value of the goodwill and other intangible property
of such Loan Party) is not less than the amount that will be required to pay the
probable liability on its debts as they become absolute and matured, and (c) it
is able to realize upon its assets and pay its debts and other liabilities and
commitments (including Guarantee Obligations) as they mature in the normal
course of business. Each Loan Party (a) does not intend to, and does not believe
that it will, incur debts or liabilities beyond its ability to pay as such debts
and liabilities mature, and (b) is not engaged in a business or transaction, or
about to engage in a business or transaction, for which its property would
constitute unreasonably small capital after giving due consideration to the
prevailing practice and industry in which it is engaged.

compliance by all tenants and all subtenants, if any, with, all Environmental
Laws and obtain and comply with and maintain, and require that all tenants and
subtenants obtain and comply with and maintain, any and all licenses, approvals,
registrations or permits required by Environmental Laws, except to the extent

claims, demands, penalties, fines, liabilities, settlements, damages, costs and
expenses of whatever kind or nature known or unknown, contingent or otherwise,
arising out of, or in any way relating to any violation of or noncompliance with
or liability under any Environmental Laws, or any orders, requirements or
demands of Governmental Authorities related thereto which in each case relate to
or arise in connection with any Loan Party, any Property or any activities
relating to any other property or business of a Loan Party or the enforcement of
any rights provided herein or in the other Loan Documents, including, without
limitation, reasonable attorneys' and consultants' fees, response costs,
investigation and laboratory fees, court costs and litigation expenses, except
to the extent that any of the foregoing arise out of the gross negligence or
willful misconduct of any of the foregoing enumerated parties. This indemnity
shall continue in full force and effect regardless of the termination of this
Agreement and the payment of the Loans.

                  6.9 Subsequent Credit Terms. Notify the Agent in writing prior
to entering into any new credit agreement or facility or any amendment or
modification of any existing credit arrangement or facility, pursuant to which a
Loan Party agrees to financial, affirmative and/or negative covenants which are
less favorable in any material respect to a Loan Party than those contained in
this Agreement. Effective upon a Loan Party's entry into any such agreement or
facility, amendment or modification, this Agreement shall unless otherwise
agreed by the Required Lenders, be deemed to be automatically and immediately
amended by adding any covenants, terms and/or conditions of such other agreement
(until such agreement is terminated and all amounts owing thereunder are
repaid); provided, however, that the foregoing shall not be applicable to or be
deemed to affect any provision of this Agreement which is less favorable to such
Loan Party or Loan Parties than any such agreement, facility, amendment or
modification. The Borrower hereby agrees promptly to execute and deliver any and
all such documents and instruments and to take all such further actions as the
Agent may, in its sole discretion, deem necessary or appropriate to effectuate
the provisions of this subsection 6.9.

                  6.10 New Subsidiaries. Notify the Agent as soon as practicable

Borrower shall cause any Subsidiary of the Borrower to execute and deliver to
the Agent a Guarantee pursuant to which such Subsidiary shall guarantee the
obligations of the Borrower hereunder and under the other Loan Documents. The
Borrower shall execute and deliver and cause any Guarantor to execute and
deliver to the Agent such further documents and take such actions as the Agent
may reasonably request. Notwithstanding the foregoing, no Subsidiary of the
Borrower 

                                      54

<PAGE>


shall be required to execute and deliver a Guarantee if such Subsidiary is a
Foreign Subsidiary and, in the reasonable opinion of the Borrower and its
outside counsel, the execution of such Guarantee would result in adverse tax
consequences to the Borrower and/or its Subsidiaries.

                  6.11 Management Changes. Notify the Agent in writing within
thirty (30) days after any change of its executive officers.

                  6.12 Subordination of Intercompany Loans, Other Loans and
Advances to the Borrower. Cause any intercompany indebtedness, loans or advances
owed by a Loan Party to any Subsidiary of the Borrower that is not a Loan Party
(other than indebtedness, loans or advances incurred in the ordinary course of
business) to be subordinated on terms satisfactory to the Agent to the Loans,
the L/C Obligations and other obligations owed to the Agent and the Lenders
hereunder or under the other Loan Documents.

against a Loan Party or any of its Material Subsidiaries involving in the
aggregate a liability (excluding any such judgments or orders which are fully
covered by insurance, subject to any customary deductible, and under which the
applicable insurance carrier has acknowledged such full coverage in writing) of
$1,000,000 or more and all such judgments or decrees shall not have been
vacated, discharged, settled, satisfied or paid, or stayed or bonded pending
appeal, within 60 days from the entry thereof; or

                           (h) Without limiting any other representations or
covenants relating to environmental matters, a Loan Party or any Subsidiary
thereof shall fail to (i) comply with or require compliance by all tenants and,
to the extent possible, all subtenants, if any, with all Environmental Laws or
obtain and comply with and maintain, or require that all tenants and, to the
extent possible, all subtenants, obtain and comply with and maintain, any and

(ii) comply with all lawful and binding orders and directives of all
Governmental Authorities respecting Environmental Laws except to the extent that
failure to so comply could not reasonably be expected to have a Material Adverse

                           (i) Without limiting any other representations or

<PAGE>


in any "prohibited transaction" (as defined in Section 406 of ERISA or Section
4975 of the Code) involving any Plan, (ii) any "accumulated funding deficiency"
(as defined in Section 302 of ERISA), whether or not waived, shall exist with
respect to any Plan or any Lien in favor of the PBGC or a Plan shall arise on
the assets of a Loan Party or any Commonly Controlled Entity, (iii) a Reportable
Event shall occur with respect to, or proceedings shall commence to have a
trustee appointed, or a trustee shall be appointed, to administer or to

of Title IV of ERISA, (v) a Loan Party or any Commonly Controlled Entity shall,
or in the reasonable opinion of the Required Lenders is likely to, incur any
liability in connection with a withdrawal from, or the Insolvency or
Reorganization of, a Multiemployer Plan or (vi) any other event or condition
shall occur or exist in regard to a Plan; and in each case in clauses (i)
through (vi) above, such event or condition, together with all other such events
or conditions, if any, could reasonably be expected to have a Material Adverse
Effect; or

                           (j) Any Change in Control shall occur; or

                           (k) Any other event shall have occurred which
could reasonably be expected to have a Material Adverse Effect;

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) above with respect to the Borrower,
automatically the Commitments shall immediately terminate and the Loans
hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement (including all amounts of L/C Obligations, whether or not the
beneficiaries of the then outstanding Letters of Credit shall have presented the
documents required thereunder) and the Notes shall automatically and immediately
become due and payable, and (B) if such event is any other Event of Default,
either or both of the following actions may be taken: (i) with the consent of
the Required Lenders, the Agent may, or upon the written request of the Required
Lenders, the Agent shall, by notice to the Borrower declare the Commitments to
be terminated forthwith, whereupon the Commitments shall immediately terminate;
and (ii) with the consent of the Required Lenders, the Agent may, or upon the
written request of the Required Lenders, the Agent shall, by notice of default
to the Borrower, declare the Loans hereunder (with accrued interest thereon) and
all other amounts owing under this Agreement (including, without limitation, all
amounts of L/C Obligations, whether or not the beneficiaries of the then

                                      65

<PAGE>


outstanding Letters of Credit shall have presented the documents required
thereunder) and the Notes to be due and payable forthwith, whereupon the same
shall immediately become due and payable. With respect to all Letters of Credit
with respect to which presentment for honor shall not have occurred at the time
of an acceleration pursuant to this subsection 8.1, the Borrower shall at such
time deposit in a cash collateral account opened by the Agent an amount equal to
the L/C Coverage Requirement for each such Letter of Credit. The Borrower hereby
grants to the Agent, for the benefit of the Issuing Bank and the L/C
Participants, a security interest in such cash collateral to secure all
obligations of the Loan Parties under this Agreement and the other Loan
Documents. Amounts held in such cash collateral account shall be applied by the
Agent to the payment of drafts drawn under such Letters of Credit, and the
unused portion thereof after all such Letters of Credit shall have expired or
been fully drawn upon, if any, shall be applied to repay other obligations of
the Loan Parties hereunder and under the other Loan Documents. After all such
Letters of Credit shall have expired or been fully drawn upon, all Reimbursement
Obligations shall have been satisfied and all other obligations of the Loan
Parties hereunder and under the other Loan Documents shall have been paid in
full, the balance, if any, in such cash collateral account shall be returned to
the Borrower or as otherwise directed by a court of competent jurisdiction. The
Borrower shall execute and deliver to the Agent, for the account of the Issuing
Bank and the L/C Participants, such further documents and instruments as the
Agent may request to evidence the creation and perfection of the within security
interest in such cash collateral account. Except as expressly provided above in
this Section, presentment, demand, protest and all other notices of any kind are
hereby expressly waived.


                              SECTION 9. THE AGENT

                  9.1 Appointment. Each Lender hereby irrevocably designates and
appoints PNC as the Agent of such Lender under this Agreement and the other Loan
Documents, and each such Lender irrevocably authorizes PNC, as the Agent for
such Lender, to take such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to the Agent by the terms of this
Agreement and the other Loan Documents, together with such other powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
elsewhere in this Agreement and the other Loan Documents, the Agent shall 

                                     66

<PAGE>


not have any duties or responsibilities, except those expressly set forth herein
or therein, or any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into this Agreement and the other Loan Documents or otherwise exist
against the Agent. PNC agrees to act as the Agent on behalf of the Lenders to
the extent provided in this Agreement and the other Loan Documents.

                  9.2 Delegation of Duties. The Agent may execute any of its
duties under this Agreement and the other Loan Documents by or through agents or
attorneys-in-fact and shall be entitled to engage and pay for the advice and
services of counsel concerning all matters pertaining to such duties. The Agent
shall not be responsible to the Lenders for the negligence or misconduct of any
agents or attorneys in-fact selected by it with reasonable care.

                  9.3 Exculpatory Provisions. Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(a) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Agreement or the other Loan Documents
(except for its or such Person's own gross negligence or willful misconduct) or
(b) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by a Loan Party or any officer
thereof contained in this Agreement, the other Loan Documents or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection with, this Agreement or for the
value, validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement or the other Loan Documents or for any failure of the Loan
Parties (or any of them) to perform their obligations hereunder or thereunder.
The Agent shall not be under any obligation to any Lender to ascertain or to
inquire as to the observance or performance of any of the agreements contained
in, or conditions of, this Agreement or the other Loan Documents, or to inspect
the properties, books or records of the Loan Parties (or any of them).

                  9.4 Reliance by Agent. The Agent shall be entitled to rely,
and shall be fully protected in relying, upon any Note, writing, resolution,
notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy,
telex or teletype message, statement, order or other document or conversation
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to one or more of the Loan Parties),
independent accountants and other 

                                      67

<PAGE>


experts selected by the Agent. The Agent may deem and treat the payee of any
Note as the owner thereof for all purposes unless a written notice of
assignment, negotiation or transfer thereof shall have been filed with the
Agent. The Agent shall be fully justified in failing or refusing to take any
action under this Agreement or the other Loan Documents unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, under this Agreement or
the other Loan Documents in accordance with a request of the Required Lenders,
and such request and any action taken or failure to act pursuant thereto shall
be binding upon all the Lenders and all future holders of the Loans.

                  9.5 Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless it has received notice from a Lender or the Borrower referring
to this Agreement, describing such Default or Event of Default and stating that
such notice is a "notice of default". In the event that the Agent receives such
a notice, the Agent shall give notice thereof to the Lenders. The Agent shall
take such action with respect to such Default or Event of Default as shall be
reasonably directed by the Required Lenders; provided that unless and until the
Agent shall have received such directions, it may (but shall not be obligated
to) take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interests of
the Lenders.

                  9.6 Non-Reliance on Agent and Other Lenders. Each Lender
expressly acknowledges that neither the Agent nor any of its respective
officers, directors, employees, agents, attorneys-in-fact or Affiliates has made
any representations or warranties to it and that no act by the Agent hereinafter
taken, including any review of the affairs of the Loan Parties, shall be deemed
to constitute any representation or warranty by the Agent to any Lender. Each
Lender represents to the Agent that it has, independently and without reliance
upon the Agent or any other Lender, and based on such documents and information
as it has deemed appropriate, made its own appraisal of and investigation into
the business, operations, property, financial and other condition and
creditworthiness of the Loan Parties and made its own decision to make its Loans
hereunder and enter into this Agreement and each other Loan Document to which it
is a party. 

                                       68

<PAGE>


Each Lender also represents that it will, independently and without
reliance upon the 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 analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigation as
it deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Loan Parties. Except
for notices, reports and other documents expressly required to be furnished to
the Lenders by the Agent hereunder, the Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of the Loan Parties which may come
into the possession of the Agent or any of its officers, directors, employees,
agents, attorneys-in-fact or Affiliates.

                  9.7 Indemnification. The Lenders agree to indemnify the Agent
in its capacity as such (to the extent not reimbursed by the Loan Parties and
without limiting the obligation, if any, of the Loan Parties to do so) in
Dollars, 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
whatsoever which may at any time (including, without limitation, at any time
following the payment of the Loans) be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of this Agreement, the
other Loan Documents, or any documents contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by the Agent under or in connection with any of the foregoing;
provided that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting solely from the Agent's gross
negligence or willful misconduct. The agreements in this subsection 9.7 shall
survive the payment of the Loans and all other amounts payable hereunder.

                  9.8 Agent in its Individual Capacity. The Agent and its
Affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Loan Parties (or any of them) as though the Agent were
not the Agent hereunder. With respect to its Loans made or renewed by it and
with respect to any Letter of Credit issued or participated in by it, the Agent
shall have the same rights and powers under this Agreement and the other Loan
Documents as any Lender and may exercise the same as though it were not the
Agent, and the terms "Lender" and "Lenders" shall include the Agent in its
individual 

                                        69

<PAGE>


capacity.

                  9.9 Successor Agent. The Agent may resign as Agent hereunder
and under the other Loan Documents upon 30 days' notice to the Lenders and the
Borrower. If the Agent shall resign, then the Required Lenders shall appoint
from among the Lenders a successor Agent for the Lenders, which appointment
shall be subject to (unless an Event of Default shall have occurred and be
continuing) the approval of the Borrower (which approval shall not be
unreasonably withheld). Any rejection by the Borrower of a successor Agent shall
specify the reasons for such rejection. Failure of the Borrower to approve or
reject a successor agent within ten days following request for approval shall be
deemed to constitute approval. Upon such appointment and approval, such
successor agent shall succeed to the rights, powers and duties of the Agent and
the term "Agent" shall mean such successor agent effective upon its appointment
and the former Agent's rights, powers and duties as Agent shall be terminated,
without any other or further act or deed on the part of such former Agent or any
of the parties to this Agreement or the other Loan Documents or any holders of
the Loans. After any retiring Agent's resignation, the provisions of this
Section 9 shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Agent under this Agreement.

                  9.10 Beneficiaries. Except as expressly provided herein, the
provisions of this Section 9 are solely for the benefit of the Agent and the
Lenders, and the Loan Parties shall not have any rights to rely on or enforce
any of the provisions hereof. In performing its functions and duties under this
Agreement and the other Loan Documents, the Agent shall act solely as agent of
the Lenders and does not assume and shall not be deemed to have assumed any
obligation toward or relationship of agency or trust with or for the Loan
Parties.


                            SECTION 10. MISCELLANEOUS

                  10.1 Amendments and Waivers. Neither this Agreement, any other
Loan Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this subsection. With the
written consent of the Required Lenders, the Agent and the Borrower may, from
time to time, enter into written amendments (including letter amendments),
supplements or modifications hereto and to the other Loan Documents for the
purpose of adding any provisions to this Agreement or any other Loan Document or
changing in any manner the rights of the Lenders or of the Loan Parties
hereunder or thereunder or waiving, on such terms and conditions as the Agent
may specify in such instrument, any of the requirements of this Agreement or any
other Loan Document or any Default or Event of 

                                      70

<PAGE>


Default and its consequences; provided, however, that no such waiver and no such
amendment, supplement or modification shall directly or indirectly (a) reduce
the amount or extend the maturity of any Note or any installment thereof, or
reduce the rate of interest or extend the time of payment of interest thereon,
or reduce any fee payable to any Lender hereunder or extend the period for
payment thereof, or change the duration or the amount of any Lender's
Commitment, in each case without the consent of the Lender affected thereby, (b)
amend, modify or waive any provision of this subsection or reduce the percentage
specified in the definition of Required Lenders, or consent to the assignment or
transfer by the Loan Parties of any of their rights and obligations under this
Agreement and the other Loan Documents, or release the Borrower as a Loan Party,
in each case without the written consent of all the Lenders, (c) amend, modify
or waive any provision of Section 9 without the written consent of the then
Agent or (d) amend, modify or waive any provision of this Agreement relating to
any outstanding Letter of Credit without the written consent of the Issuing
Bank. Any such waiver and any such amendment, supplement or modification shall
apply equally to each of the Lenders and shall be binding upon the Loan Parties,
the Lenders, the Agent and all future holders of the Notes. In the case of any
waiver, the Loan Parties, the Lenders and the Agent shall be restored to their
former position and rights hereunder and under the outstanding Notes, and any
Default or Event of Default waived shall be deemed to be cured and not
continuing; but no such waiver shall extend to any subsequent or other Default
or Event of Default, or impair any right consequent thereon.

respective parties hereto to be effective shall be in writing (including by

promises and agreements by or on behalf of the Borrower, the Agent or the
Lenders that are contained in this Agreement shall bind and inure to the benefit
of their respective successors and assigns. The Borrower may not assign or
transfer any of its rights or obligations under this Agreement or the other Loan
Documents without the prior written consent of each Lender.

                           (b) Each Lender may, in accordance with applicable
law, sell to any Lender or Affiliate thereof and, with the consent of the
Borrower and the Agent(which consents shall not be unreasonably withheld), to
one or more banks, financial institutions or "accredited investors" (as defined
in Regulation D of the Securities Act of 1933, as amended) (each, a "Purchasing
Lender") all or a pro rata portion of its interests, rights and obligations
under this Agreement, the Notes and the other Loan Documents, other than as
Agent or Issuing Bank (i.e., all or a pro rata portion of its Commitments and
the Loans at the time owing to it and the Notes held by it); provided, however,
that (i) so long as the Commitments are then in effect, such assignment shall be
in an amount not less than $5,000,000 (or such lesser amount as (x) the Borrower
and the Agent shall agree in their sole discretion or (y) is an assignment of
all of a Lender's interests under the Commitments and its Loans), (ii) the
parties to each such assignment shall execute and deliver to the Agent and the
Borrower for its acceptance and recording in the Register an Assignment and
Acceptance, together with the Note or Notes subject to such assignment and a
processing and recordation fee of $3,500. Upon acceptance and recording pursuant
to paragraph (e) of this subsection 10.6, from and after the effective date
specified in an Assignment and Acceptance, which effective date shall be at
least five Business Days after the execution and delivery thereof to the
Borrower and the Agent (or such shorter period as the Agent and the Borrower may
agree in their sole discretion), (A) such Purchasing Lender shall be a party
hereto and, to the extent of the interest assigned by such Assignment and
Acceptance, have the rights and obligations of a Lender under this Agreement and
(B) the assigning Lender thereunder shall, to the extent of the interest
assigned by such 

                                      74
<PAGE>


Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining
portion of an assigning Lender's rights and obligations under this Agreement and
the other Loan Documents, such Lender shall cease to be a party hereto but shall
continue to be entitled to the benefits of subsections 3.9, 3.10, 3.11 and 10.5
(to the extent that such Lender's entitlement to such benefits arose out of such
Lender's position as a Lender prior to the applicable assignment). Such
Assignment and Acceptance shall be deemed to amend this Agreement to the extent,
and only to the extent, necessary to reflect the addition of such Purchasing
Lender and the resulting amounts and percentages held by the Lenders after
giving effect to the purchase by such Purchasing Lender of all or a portion of
the rights and obligations of such assigning Lender under this Agreement and the
other Loan Documents. Notwithstanding any provision of this subsection 10.6, the
consent of the Borrower shall not be required for any assignment which occurs at
any time when an Event of Default shall have occurred and be continuing under
subsection 8.1(a) or subsection 8.1(f).

                           (c) By executing and delivering an Assignment and
Acceptance, the assigning Lender thereunder and the Purchasing Lender thereunder
shall be deemed to confirm to and agree with each other and the other parties
hereto as follows: (i) such assigning Lender warrants that it is the legal and
beneficial owner of the interest being assigned thereby, free and clear of any
adverse claim, (ii) except as set forth in (i) above, such assigning Lender
makes no representation or warranty and assumes no responsibility with respect
to any statements, warranties or representations made in or in connection with
this Agreement or the other Loan Documents, or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement,
the other Loan Documents or any other instrument or document furnished pursuant
hereto or thereto, or the financial condition of the Loan Parties or any
Subsidiary thereof or the performance or observance by the Loan Parties or any
Subsidiary thereof of any of its or their obligations under this Agreement or
the other Loan Documents or any other instrument or document furnished pursuant
hereto or thereto; (iii) such assignee represents and warrants that it is
legally authorized to enter into such Assignment and Acceptance; (iv) such
Purchasing Lender confirms that it has received a copy of this Agreement,
together with copies of the most recent financial statements delivered pursuant
to subsection 6.1 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (v) such Purchasing Lender will independently and
without reliance upon the Agent, such assigning Lender or any other Lender and
based on such documents and information as it 

                                      75

<PAGE>


shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement and the other Loan Documents;
(vi) such Purchasing Lender appoints and authorizes the Agent to take such
action as agent on its behalf and to exercise such powers under this Agreement
and the other Loan Documents as are delegated to the Agent by the terms hereof
or thereof, together with such powers as are reasonably incidental thereto; and
(vii) such Purchasing Lender agrees that it will perform in accordance with
their terms all the obligations which by the terms of this Agreement and the
other Loan Documents are required to be performed by it as a Lender including,
if it is becoming a Lender and is organized under the laws of a jurisdiction
outside the United States, its obligation pursuant to subsection 3.10 to deliver
the forms prescribed by the Internal Revenue Service of the United States
certifying as to the Purchasing Lender's exemption from United States
withholding taxes with respect to all payments to be made to the Purchasing
Lender under this Agreement.

                           (d) The Agent shall maintain at its offices in
Philadelphia, Pennsylvania a copy of each Assignment and Acceptance and the
names and addresses of the Lenders, and the Commitment(s) of, and principal
amount of the Loans and L/C Obligations owing to, each Lender pursuant to the
terms hereof from time to time (the "Register"). The entries in the Register
shall be conclusive in the absence of manifest error and the Borrower, the Agent
and the Lenders may treat each Person whose name is recorded in the Register
pursuant to the terms hereof as a Lender hereunder for all purposes of this
Agreement. The Register shall be available for inspection by the Borrower and
any Lender at any reasonable time and from time to time upon reasonable prior
notice.

                           (e) Upon its receipt of a duly completed Assignment
and Acceptance executed by an assigning Lender and a Purchasing Lender (and in
the case of a Purchasing Lender that is not then a Lender or an Affiliate
thereof, by the Borrower and the Agent) together with the Note or Notes subject
to such assignment and the processing and recordation fee referred to in
paragraph (b) above, the Agent shall promptly (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register and
(iii) give notice thereof to the Lenders. Within five Business Days after
receipt of notice, the Borrower, at its own expense, shall execute and deliver
to the Agent, in exchange for the surrender of the original Note(s) (A) a new
Note to the order of such Purchasing Lender in an amount equal to the Commitment
assumed and (B) if the assigning Lender 

                                        76

<PAGE>


has retained a Commitment or, with respect to assignments occurring after the
termination of the Commitments, a portion of the Loans, a new Note to the order
of such assignor in the respective amount equal to the Loan retained by it
and/or the Commitment retained by it, as the case may be. Such new Notes shall
be in an aggregate principal amount equal to the aggregate principal amount of
such surrendered Note(s); such new Notes shall be dated the date of the
surrendered Notes which they replace and shall otherwise be in substantially the
form of Exhibit A. Canceled Notes shall be returned to the Borrower.

                           (f) Each Lender may without the consent of the
Borrower or the Agent (except to the extent provided below) sell participations
to one or more banks or other entities (each a "Participant") in any Loan owing
to such Lender, the Note held by such Lender, any Commitment of such Lender or
any other interest of such Lender hereunder and under the other Loan Documents,
provided, however, that (i) such Lender's obligations under this Agreement to
the other parties to this Agreement shall remain unchanged, (ii) such Lender
shall remain solely responsible to the other parties hereto for the performance
of such obligations, (iii) such Lender shall remain the holder of any such Note
for all purposes under this Agreement and the other Loan Documents, (iv) the
Borrower, the Lenders and the Agent shall continue to deal solely and directly
with such Lender in connection with such Lender's rights and obligations under
this Agreement and the other Loan Documents, (v) in any proceeding under the
Bankruptcy Code such Lender shall be, to the extent permitted by law, the sole
representative with respect to the obligations held in the name of such Lender,
whether for its own account or for the account of any Participant, and (vi) such
Lender shall retain the sole right to approve, without the consent of any
Participant, any amendment, modification or waiver of any provision of this
Agreement or the Note held by such Lender or any other Loan Document, other than
any such amendment, modification or waiver with respect to any Loan or
Commitment in which such Participant has an interest that forgives principal,
interest or fees or reduces the interest rate or fees payable with respect to
any such Loan or Commitment, postpones any date fixed for any regularly
scheduled payment of principal of, or interest or fees on, any such Loan, or
releases the Borrower from liability with respect to such Loan.

                           (g) If amounts outstanding under this Agreement and
the Notes are due or unpaid, or shall have been declared or shall have become
due and payable upon the occurrence of an Event of Default, each Participant
shall be deemed to have the right of set-off in respect of its participating
interest in amounts owing under this Agreement, any Note and the other Loan
Documents to the same extent as if the amount of its participating interest 

                                      77

<PAGE>


were owing directly to it as a Lender under this Agreement or any Note, provided
that in purchasing such participation such Participant shall be deemed to have
agreed to share with the Lenders the proceeds thereof as provided in subsection
10.8. The Borrower also agrees that each Participant shall be entitled to the
benefits of subsections 3.9, 3.10, 3.11 and 10.5 with respect to its
participation in the Commitments and the Loans outstanding from time to time;
provided, that no Participant shall be entitled to receive any greater amount
pursuant to such subsections than the assigning Lender would have been entitled
to receive in respect of the amount of the participation transferred by such
assigning Lender to such Participant had no such transfer occurred.

                           (h) If any Participant of a Lender is organized under
the laws of any jurisdiction other than the United States or any state thereof,
the assigning Lender, concurrently with the sale of a participating interest to
such Participant, shall cause such Participant (i) to represent to the assigning
Lender (for the benefit of the assigning Lender, the other Lenders, the Agent
and the Borrower) that under applicable law and treaties no taxes will be
required to be withheld by the Agent, the Borrower or the assigning Lender with
respect to any payments to be made to such Participant in respect of its
participation in the Loans and (ii) to agree (for the benefit of the assigning
Lender, the other Lenders, the Agent and the Borrower) that it will deliver the
tax forms and other documents required to be delivered pursuant to paragraph
3.10(b) and comply from time to time with all applicable U.S. laws and
regulations with respect to withholding tax exemptions.

                           (i) Any Lender may at any time assign all or any
portion of its rights under this Agreement and the Note issued to it to a
Federal Reserve Bank; provided that no such assignment shall release a Lender
from any of its obligations hereunder.

                  10.7 Disclosure of Information. Unless otherwise consented to
by the Borrower in writing, each of the Lenders and the Agent agrees (on behalf
of itself and each of its affiliates, directors, officers, employees and
representatives) to use reasonable precautions to keep confidential, in
accordance with its customary procedures for handling confidential information
of the same nature and in accordance with safe and sound banking practices, any
non-public information supplied to it by the Borrower pursuant to this
Agreement; provided that nothing herein shall limit the disclosure of any such
information (a) to the extent required by statute, rule, regulation or judicial
process, (b) to counsel for any Lender or the Agent, (c) to bank examiners,
auditors or accountants, (d) to the Agent or any other Lender, (e) in connection
with any litigation to which any one or 

                                        78

<PAGE>


more of the Lenders or the Agent is a party involving the Borrower, any other
Loan Party, or any Subsidiary thereof or any of its or their properties or in
any way relating to this Agreement or any other Loan Documents or any Loans or
other obligations of one or more of the Loan Parties to the Agent or any Lender
and (f) to any participant or Purchasing Lender (or prospective participant or
Purchasing Lender) so long as such Participant or Purchasing Lender (or
prospective participant or Purchasing Lender) agrees to comply with the
requirements of this subsection.

                  10.8 Adjustments; Set-off. (a) If any Lender (a "benefitted
Lender") shall at any time receive any payment of all or part of its Loans or
the Reimbursement Obligation owing to it, or interest thereon, or receive any
collateral in respect thereof (whether voluntarily or involuntarily, by set-off,
pursuant to events or proceedings of the nature referred to in subsection
8.1(f), or otherwise), in a greater proportion than any such payment to or
collateral received by any other Lender, if any, in respect of such other
Lender's Loans or the Reimbursement Obligations owing to it, or interest
thereon, such benefitted Lender shall purchase for cash from the other Lenders
such portion of each such other Lender's Loans or the Reimbursement Obligations
owing to it, or shall provide such other Lenders with the benefits of any such
collateral, or the proceeds thereof, as shall be necessary to cause such
benefitted Lender to share the excess payment or benefits of such collateral or
proceeds ratably with each of the Lenders; provided, however, that if all or any
portion of such excess payment or benefits is thereafter recovered from such
benefitted Lender, such purchase shall be rescinded, and the purchase price and
benefits returned, to the extent of such recovery, but without interest. The
Borrower agrees that each Lender so purchasing a portion of another Lender's
Loans or Reimbursement Obligations may exercise all rights of payment
(including, without limitation, rights of set-off) with respect to such portion
as fully as if such Lender were the direct holder of such portion.

                           (b) In addition to any rights and remedies of the
Lenders provided by law, upon the occurrence and during the continuance of an
Event of Default, each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by the Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by the
Borrower hereunder or under the Notes (whether at the stated maturity, by
acceleration or otherwise) to set-off and appropriate and apply against such
amount any and all deposits 

                                      79

<PAGE>


(general or special, time or demand, provisional or final), in any currency, and
any other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or owing by such Lender to or for the credit or the account of the
Borrower. Each Lender agrees promptly to notify the Borrower and the Agent after
any such set-off and application made by such Lender, provided that the failure
to give such notice shall not affect the validity of such set-off and
application.

                  10.9 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts,
and all of said counterparts taken together shall be deemed to constitute one
and the same instrument.

                  10.10 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  10.11 Integration. This Agreement and the other Loan Documents
represent the agreement of the parties hereto with respect to the subject matter
hereof, and there are no promises, undertakings, representations or warranties
by the Agent or any Lender relative to the subject matter hereof not expressly
set forth or referred to herein or in the other Loan Documents.

                  10.12  GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS
AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE COMMONWEALTH OF

inconvenient court and agrees not to plead or claim the same;

                           (c) waives and hereby acknowledges that it is
estopped from raising any objection based on forum non conveniens, any claim
that any of the above-referenced courts lack proper venue or any objection that
any of such courts lack personal jurisdiction over it so as to prohibit such
courts from adjudicating any issues raised in a complaint filed with such courts
against the Borrower concerning this Agreement or the other Loan Documents;

                           (d) acknowledges and agrees that the choice of forum
contained in this subsection 10.13 shall not be deemed to preclude the
enforcement of any judgment obtained in any forum or the taking of any action
under the Loan Documents to enforce the same in any appropriate jurisdiction;

                           (e) agrees that service of process in any such action
or proceeding may be effected by mailing a copy thereof by registered or

the Borrower at its address set forth in Section 10.2 or at such other address
of which the Agent shall have been notified pursuant to this Agreement;

                           (f) agrees that nothing herein shall affect the right
to effect service of process in any other manner permitted by law or shall limit
the right to sue in any other jurisdiction; and

                           (g) waives, to the maximum extent not prohibited by
law, any right it may have to claim or recover in any legal action or proceeding
referred to in this subsection any special, exemplary, punitive or consequential
damages.
