per share, of InSight (the InSight Series A Preferred Stock), (v) each 
outstanding share of common stock, par value $.01 per share, of Maxum (Maxum 
Common Stock) was converted into the right to receive .598 of a share of 
Common Stock, (vi) each outstanding share of Series B Preferred Stock, par 
value $.01 per share, of Maxum (the Maxum Series B Preferred Stock), which 
was issued immediately prior to the consummation of the Merger, was converted 
into the right to receive 83.392 shares of InSight Series A Preferred Stock, 
and (vii) each outstanding option, warrant or other right to purchase AHS 
Common Stock and Maxum Common Stock was converted into the right to acquire, 
on the same terms and conditions, shares of Common Stock, with the number of 
shares and exercise price applicable to such option, warrant or other right 
adjusted based on the applicable exchange ratio for the underlying AHS Common 
Stock or Maxum Common Stock.

Concurrent with the consummation of the Merger, AHS and MHC completed a debt
restructuring with General Electric Company (GE), the primary creditor of MHC
and AHS.  This restructuring resulted in the reduction of certain debt and
operating lease obligations and cancellation of certain stock warrants of MHC
and AHS in exchange for, among other things, the issuance to GE, immediately
prior to the consummation of the Merger, of Maxum Series B Preferred Stock and
AHS Series C Preferred Stock.

At the effective time of the Merger, Maxum Series B Preferred Stock and AHS
Series C Preferred Stock issued to GE was converted into the right to receive
such number of shares of InSight Series A Preferred Stock that is convertible
into such number of shares of Common Stock representing approximately 48% of
InSight Common Stock outstanding at the effective time of the Merger (after
giving effect to such conversion).  

Under an amended equipment maintenance service agreement, GE was also entitled
to receive for ten years an annual supplemental service fee equal to 14% of the
Company's pretax income, subject to certain adjustments.  In connection with the
Company's recapitalization described below, GE surrendered its rights under the
amended equipment service agreement to receive the supplemental service fee.

The Merger was accounted for using the purchase method of accounting in
accordance with generally accepted accounting principles.  MHC was treated as
the acquiror for accounting purposes. 

On September 13, 1996, AHS changed its name to InSight Health Corp. (IHC).

On October 14, 1997, InSight consummated a recapitalization (Recapitalization)
pursuant to which (a) certain investors affiliated with TC Group, LLC and its
affiliates (collectively, Carlyle), a private merchant bank headquartered in
Washington, D.C., made a cash investment of $25 million in the Company and
received therefor (i) 25,000 shares of newly issued Convertible Preferred Stock,
Series B of the Company, par value $0.001 per share (Series B Preferred Stock),
initially convertible, at the option of the holders thereof, in the aggregate
into 2,985,075 shares of Common Stock, and (ii) warrants (Carlyle Warrants) to
purchase up to 250,000 shares of Common Stock at the current exercise price of
$10.00 per share; (b) GE (i) surrendered its rights under the amended equipment


                                       8

<PAGE>

service agreement to receive supplemental service fee payments equal to 14% 
of pretax income in exchange for (i) the issuance of 7,000 shares of newly 
issued Convertible Preferred Stock, Series C of the Company, par value $0.001 
per share (Series C Preferred Stock) initially convertible, at the option of 
GE, in the aggregate into 835,821 shares of Common Stock, (ii) warrants (GE 
Warrants) to purchase up to 250,000 shares of Common Stock at the current 
exercise price of $10.00 per share, and (iii) exchanged all of its InSight 
Series A Preferred Stock for an additional 20,953 shares of Series C 
Preferred Stock, initially convertible, at the option of the holders thereof, 
in the aggregate into 2,501,760 shares of Common Stock; and (c) the Company 
executed a Credit Agreement with NationsBank, N.A. pursuant to which 
NationsBank, as agent and lender, provided a total of $125 million in senior 
secured credit (Bank Financing), including (i) a $50 million term loan 
facility consisting of a $20 million tranche with increasing amortization 
over a five- year period and a $30 million tranche with increasing 
amortization over a seven-year period, principally repayable in years 6 and 
7, (ii) a $25 million revolving working capital facility with a five-year 
maturity, and (iii) a $50 million acquisition facility, which was increased 
by an additional $25 million on December 19, 1997.

The terms of the Series B Preferred Stock and the Series C Preferred Stock 
(collectively, Preferred Stock) are substantially the same.  The Preferred 
Stock has a liquidation preference of $1,000 per share.  It will participate 
in any dividends paid with respect to the Common Stock.  There is no 
mandatory or optional redemption provision for the Preferred Stock.  The 
Preferred Stock is convertible at an initial conversion price of $8.375 per 
share.

For so long as Carlyle and its affiliates own at least 33% of the Series B 
Preferred Stock or GE and its affiliates own at least 33% of the Series C 
Preferred Stock, respectively, the approval of at least 67% of the holders of 
such series of Preferred Stock is required before the Company may take 
certain actions including, but not limited to, amending its certificate of 
incorporation or bylaws, changing the number of directors or the manner in 
which directors are selected, incurring indebtedness in excess of $15 million 
in any fiscal year, issuing certain equity securities below the then current 
market price or the then applicable conversion price, acquiring equity 
interests or assets of entities for consideration equal to or greater than 
$15 million, and engaging in mergers for consideration equal to or greater 
than $15 million.  The Preferred Stock will vote with the Common Stock on an 
as-if-converted basis on all matters except the election of directors, 
subject to an aggregate maximum Preferred Stock percentage of 37% of all 
votes entitled to be cast on such matters. Assuming the conversion of all of 
the Series B Preferred Stock into Common Stock and the exercise of all of the 
Carlyle Warrants, Carlyle would own approximately 31% of the Common Stock of 
the Company, on a fully diluted basis.  Assuming the conversion of all of the 
Series C Preferred Stock and the exercise of the GE Warrants, GE would own 
approximately 34% of the Common Stock of the Company, on a fully diluted 
basis.

Pursuant to the terms of the Recapitalization, the number of directors 
comprising the Company's Board of Directors (the Board) is currently fixed at 
nine.  Six directors (Common Stock Directors) are to be elected by the common 
stockholders, one of whom (Joint Director) is to be proposed by Carlyle and 
GE and approved by a majority of the Board in its sole discretion.  Of the 
three remaining directors (Preferred Stock Directors), two are to be elected 
by the holders of the Series B Preferred Stock and one is to be elected by 
the holders of the Series C Preferred Stock, in each case acting by written 
consent and without a meeting of the common stockholders.  As long as Carlyle 
and certain affiliates thereof own an aggregate of at least 50% of the Series 
B Preferred Stock, originally purchased thereby, the holders of the Series B 
Preferred Stock will have the right to elect two Preferred Stock Directors 
and as long as Carlyle and certain affiliates thereof own an aggregate of at 
least 25% of such stock, such holders will have the right to elect one 
Preferred Stock Director. As long as GE and its affiliates own an aggregate 
of at least 25% of the Series C Preferred Stock, originally purchased 
thereby, GE will have the right to elect one Preferred Stock Director.  If 
any such ownership percentage falls below the applicable threshold, the 
Preferred Stock Director(s) formerly entitled to be elected by Carlyle or GE, 
as the case may be, will be initially appointed by the Board, and will 
thereafter be elected by the common stockholders.  The Board currently 
consists of eight directors, five of whom are Common Stock Directors and 
three of whom are Preferred Stock Directors.  The vacancy created for the 
Joint Director has not yet been filled.

At any time after October 22, 1998, all of the Series B Preferred Stock and the
Series C Preferred Stock may be converted into a newly created Convertible
Preferred Stock, Series D of the Company, par value $0.001 per share (Series D
Preferred Stock).  The Series D Preferred Stock allows the number of directors
to be automatically increased to a number which would permit each of Carlyle and
GE, by filling the newly created vacancies, to achieve representation on the
Board proportionate to their respective common stock ownership percentages on an
as-if-converted basis but would limit such representation to less than two
thirds of the Board of Directors for a certain


                                       9

<PAGE>

period of time.  The Series D Preferred Stock has a liquidation preference of 
$0.001 per share but no mandatory or optional redemption provision.  It will 
participate in any dividends paid with respect to the Common Stock and is 
convertible into 6,322,660 shares of Common Stock.  

Holders of the Preferred Stock also have a right of first offer with respect 
to future sales in certain transactions or proposed transactions not 
involving a public offering by the Company of its Common Stock or securities 
convertible into Common Stock.  Holders of the Preferred Stock are also 
entitled to certain demand and "piggyback" registration rights.

5.   INCOME PER COMMON SHARE

In fiscal 1998, the Company adopted Statement of Financial Accounting Standards
No. 128 (SFAS No. 128), Earnings Per Share (EPS).  SFAS No. 128 replaces primary
EPS and fully diluted EPS with basic EPS and diluted EPS.  Basic EPS is computed
by dividing reported earnings by weighted average shares outstanding.  Diluted
EPS is computed in the same way as the previously used fully diluted EPS, except
that the calculation now uses the average share price for the reporting period
to compute dilution from options and warrants under the treasury stock method.  

The number of shares used in computing income per common share is equal to the
weighted average number of common and common equivalent shares outstanding
during the respective period.  For the periods ended December 31, 1996, basic
EPS is equal to diluted EPS.  Common stock equivalents relating to options,
warrants and convertible preferred stock are not included for the periods ended
December 31, 1997 due to their antidilutive effect.

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

CENTERS IN OPERATION 

InSight provides diagnostic imaging, treatment and related management services
in 26 states throughout the United States. InSight's services are provided
through a network of 36 mobile magnetic resonance imaging ("MRI") facilities
("Mobile Facilities"), 29 fixed-site MRI facilities ("Fixed Facilities"), 13
multi-modality imaging centers ("Centers"), one Leksell Stereotactic Gamma Unit
treatment center ("Gamma Knife"), and one radiation oncology center.  An
additional radiation oncology center is operated by the Company as part of one
of its Centers.  The Company's operations are located throughout the United
States, with a substantial presence in California, primarily Los Angeles county,
and northern Texas, primarily the Dallas-Ft. Worth metroplex. 

At its Centers, InSight offers other services in addition to MRI including
diagnostic and fluoroscopic x-ray, mammography, diagnostic ultrasound, nuclear
medicine, nuclear cardiology, computed tomography ("CT") and cardiovascular
services.  The Company offers additional services through a variety of
arrangements including equipment rental, technologist services and
training/applications, marketing, radiology management services, patient
scheduling, utilization review and billing and collection services.

ACQUISITIONS

InSight believes a consolidation in the diagnostic imaging industry is 
occurring and is necessary in order to provide surviving companies the 
opportunity to achieve operating and administrative efficiencies through 
consolidation.  The strategy of InSight is focused on five interrelated 
initiatives:  (i) consolidation of the highly fragmented diagnostic imaging 
industry through acquisition of organizations which either strategically fit 
into its regional networking strategy or provide significant cost savings; 
(ii) development of a radiology co-source product where InSight will provide 
management services for radiology departments within hospitals; (iii) 
development of regional networks of radiology providers and physicians 
designed to provide the highest quality and most cost-effective unit of 
diagnostic information to the broadest population in a given market; (iv) 
development of a network of open MRI systems; and (v) new business 
initiatives focused on broadening its range of services to managed care 
organizations, hospitals and physician management companies to include 
radiology management services; information management services; unbundling of 
current core services such as billing and collections, technician training 
and staffing, and asset management and continued evaluation of opportunities 
with emerging technologies. InSight believes that long-term viability is 
contingent upon its ability to successfully participate in this industry 
consolidation.  As part of its consolidation strategy, InSight completed 
three acquisitions during fiscal 1997 and four to date during fiscal 1998 as 
follows:

In September 1996, InSight completed the acquisition of a Fixed Facility in
Hayward, California.  The transaction included the purchase of certain assets,
primarily diagnostic equipment.  The purchase price of approximately $2.8
million was financed by GE.

In May 1997, InSight acquired certain assets, primarily Mobile Facilities, in
Maine and New Hampshire, and assumed certain equipment related liabilities.  The
purchase price of approximately $6.8 million and an additional $0.4 million for
working capital requirements were financed by GE.

In June 1997, InSight completed the acquisition of a Center in Chattanooga,
Tennessee.  The transaction included the purchase of certain assets, primarily
diagnostic equipment, and the assumption of certain equipment related
liabilities.  The purchase price of approximately $9.0 million was financed by
GE. 

In July 1997, InSight completed the acquisition of a Center in Columbus, Ohio. 
As part of this transaction, InSight also acquired a majority ownership interest
in the development of a new Center in Dublin, Ohio.  The transactions included
the purchase of certain assets, primarily diagnostic equipment, and the
assumption of certain equipment related liabilities.  The purchase price of
approximately $5.5 million and approximately $0.5 million for the Center under
development were financed by GE.

In November 1997, InSight completed the acquisition of a Center in Murfreesboro,
Tennessee. The Bank Financing discussed below was used to finance the purchase
price of approximately $2.3 million.

In November 1997, InSight completed the acquisition of a Fixed Facility in 
Redwood City, California. The transaction included the purchase of certain 
assets, primarily diagnostic equipment. The Bank Financing discussed below 
was used to finance the purchase price of approximately $0.3 million.

                                       12

<PAGE>

In November, 1997, the Company completed the acquisition of a Center in Las
Vegas, Nevada.  The transaction included the purchase of certain assets,
primarily land, building and diagnostic equipment.  The Bank Financing discussed
below was used to finance the purchase price of approximately $10.3 million.

As discussed below, InSight has an acquisition facility in the amount of $75
million, of which approximately $62 million remains available to the Company. 
InSight believes this facility will enhance its ability to participate in the
industry consolidation.

RESULTS OF OPERATIONS 

SIX MONTHS ENDED DECEMBER 31, 1997 COMPARED TO DECEMBER 31, 1996

REVENUES:  Revenues increased approximately $12.0 million, or approximately
26.6%, for the six months ended December 31, 1997, compared to the same period
in 1996. The increase in revenues was due primarily to the acquisitions
discussed above (approximately $7.8 million) and an increase in contract
services, patient services and other revenues at existing facilities
(approximately $4.2 million).

Contract services revenues increased approximately $2.8 million, or
approximately 11.7%, for the six months ended December 31, 1997, compared to the
same period in 1996.  This increase was due primarily to the acquisitions
discussed above (approximately $1.0 million) and an increase in revenues at
existing facilities (approximately $1.8 million).  The increase at existing
facilities was due to higher utilization (approximately 8%) offset by reductions
in reimbursement (approximately 2%) from customers, primarily hospitals.

InSight's contract services revenues, primarily earned by its Mobile 
Facilities, represent approximately 46% of total revenues.  Each year 
approximately one-quarter to one-third of the contract services agreements 
are subject to renewal. It is expected that some high volume customer 
accounts will elect not to renew their agreements and instead will purchase 
or lease their own diagnostic imaging equipment and some customers may choose 
an alternative services provider.  In the past where agreements have not been 
renewed, the Company has been able to obtain replacement customer accounts; 
however, it is not always possible to obtain replacement accounts and some 
replacement accounts have been smaller than the lost account.  The 
non-renewal of a single customer agreement would not have a material impact 
on InSight's contract services revenues; however, non-renewal of several 
agreements could have a material impact on contract services revenues.  

In addition, the Company's contract services revenues with regard to its Mobile
Facilities in certain markets depend in part on some customer accounts with high
volume.  If the future reimbursement levels of such customers were to decline or
cease or if such customers were to become financially insolvent and if such
agreements were not replaced with new accounts or with the expansion of services
on existing accounts, InSight's contract services revenues would be adversely
affected.

Patient services revenues increased approximately $8.3 million, or approximately
40.7%, for the six months ended December 31, 1997, compared to the same period
in 1996.  The increase in revenues was due primarily to the acquisitions
discussed above (approximately $6.8 million), and an increase in revenues at
existing facilities (approximately $1.5 million).  The increase at existing
facilities was due to higher utilization (approximately 11%) partially offset by
nominal declines in reimbursement from third party payors.

Management believes that any future increases in revenues at existing facilities
can only be achieved by higher utilization and not by increases in procedure
prices since reimbursement is declining; however, excess capacity of diagnostic
imaging equipment, increased competition, and the expansion of managed care may
impact utilization and make it difficult for the Company to achieve revenue
increases in the future, absent the execution of provider agreements with
managed care companies and other payors, and the execution of the Company's
strategic initiatives.  No single source accounts for more than 10% of InSight's
revenues.

COSTS OF OPERATIONS:  Costs of operations increased approximately $7.2 
million, or approximately 18.1%, for the six months ended December 31, 1997, 
compared to the same period in 1996.  This increase was due primarily to an 
increase in costs due to the acquisitions discussed above (approximately $5.0 
million), and an increase in costs at existing facilities (approximately $2.2 
million).  The increase at existing facilities was due primarily to increases 
in

                                      13
<PAGE>

costs of services and depreciation and amortization.

Costs of services, including the provision for doubtful accounts, increased
approximately $5.2 million, or approximately 20.3%, for the six months ended
December 31, 1997, compared to the same period in 1996.  The increase in costs
was due primarily to the acquisitions discussed above (approximately $3.8
million) and an increase in costs at existing facilities (approximately $1.4
million).  The increase in costs at existing facilities was due primarily to (i)
salary and benefits and (ii) an increase in sales tax and property taxes, offset
by reduced costs in service supplies and equipment maintenance.

Equipment leases and depreciation and amortization increased approximately $1.9
million, or approximately 14.1%, for the six months ended December 31, 1997,
compared to the same period in 1996.  The increase was due primarily to the
acquisitions discussed above (approximately $1.3 million) and an increase in
costs at existing facilities (approximately $0.6 million).  The increase at
existing facilities was primarily due to the Company upgrading its existing
diagnostic medical equipment.

GROSS PROFIT:  Gross profit increased approximately $4.9 million during the six
months ended December 31, 1997, compared to the same period in 1996.  The
increase was due to the acquisitions discussed above (approximately $2.8
million), and an increase at existing facilities (approximately $2.1 million).

CORPORATE OPERATING EXPENSES:  Corporate operating expenses increased
approximately $0.6 million for the six months ended December 31, 1997, compared
to the same period in 1996.  The increase was primarily due to additional
consulting, legal and travel costs associated with the Company's acquisition
activities.

PROVISION FOR SUPPLEMENTAL SERVICE FEE TERMINATION:  As part of the
Recapitalization and Bank Financing discussed below, the Company issued to GE
7,000 shares of Series C Preferred Stock to terminate GE's rights to receive
supplemental service fee payments equal to 14% of InSight's pre-tax income.  The
Series C Preferred Stock was valued at $7.0 million and the Company recorded a
one-time provision of approximately $6.3 million, net of amounts previously
accrued, for the Preferred Stock issuance.

INTEREST EXPENSE NET:  Interest expense, net increased approximately $1.5 
million for the six months ended December 31, 1997, compared to the same 
period in 1996.  The increase was due primarily to additional debt related to 
the acquisitions discussed above (approximately $1.5 million) and additional 
debt related to the Company upgrading its existing diagnostic medical 
equipment, offset by reduced interest as a result of (i) the reduction in 
interest rate and the extinguishment of approximately $23 million in 
long-term debt as a result of the Recapitalization and Bank Financing 
discussed below (approximately $0.5 million), and (ii) amortization of 
long-term debt. 

PROVISION FOR INCOME TAXES:  During the six months ended December 31, 1997, 
the Company recorded a provision for income taxes of approximately $431,000.  
The provision was due primarily to increased income from the Company's 
operations and reflects the anticipated tax rate for the full fiscal year. 

INCOME (LOSS) PER COMMON SHARE:  On a basic and diluted basis, net (loss) per 
common share was ($0.49) for the six months ended December 31, 1997, compared 
to net income per common share of $0.07 for the same period in 1996.  
Excluding the one-time provision for supplemental service fee termination, 
net income per common share on a diluted basis would have been $0.42.  The 
improvement in net income per common share before provision for supplemental 
service fee termination is the result of (i) increased gross profit, (ii) an 
increase in earnings from unconsolidated partnerships, offset by (i) 
increased corporate operating expenses, (ii) increased interest expense, and 
(iii) the provision for income taxes.

THREE MONTHS ENDED DECEMBER 31, 1997 COMPARED TO DECEMBER 31, 1996

REVENUES:  Revenues increased approximately $6.3 million, or approximately
27.3%, for the three months ended December 31, 1997, compared to the same period
in 1996. The increase in revenues was due primarily to the acquisitions
discussed above (approximately $4.3 million) and an increase in contract
services, patient services and other revenues at existing facilities
(approximately $2.0 million).

Contract services revenues increased approximately $1.1 million, or
approximately 8.9%, for the three months


                                       14
<PAGE>

ended December 31, 1997, compared to the same period in 1996.  This increase 
was due primarily to the acquisitions discussed above (approximately $0.6 
million) and an increase in revenues at existing facilities (approximately 
$0.5 million).  The increase at existing facilities was due to higher 
utilization (approximately 6%) offset by reductions in reimbursement 
(approximately 2%) from customers, primarily hospitals.

Patient services revenues increased approximately $4.5 million, or approximately
43.0%, for the three months ended December 31, 1997, compared to the same period
in 1996.  The increase in revenues was due primarily to the acquisitions
discussed above (approximately $3.8 million), and an increase in revenues at
existing facilities (approximately $0.7 million).  The increase at existing
facilities was due to higher utilization (approximately 6%) partially offset by
nominal declines in reimbursement from third party payors.

COSTS OF OPERATIONS:  Costs of operations increased approximately $4.2 million,
or approximately 21.2%, for the three months ended December 31, 1997, compared
to the same period in 1996.  This increase was due primarily to the acquisitions
discussed above (approximately $2.9 million), and an increase in costs at
existing facilities (approximately $1.3 million).  The increase at existing
facilities was due primarily to increases in costs of services and depreciation
expense, primarily related to the Company upgrading its existing diagnostic
medical equipment.

Costs of services, including the provision for doubtful accounts, increased
approximately $3.1 million, or approximately 24.2%, for the three months ended
December 31, 1997, compared to the same period in 1996.  The increase in costs
was due primarily to the acquisitions discussed above (approximately $2.1
million) and an increase in costs at existing facilities (approximately $1.0
million).  The increase in costs at existing facilities was due primarily to (i)
salary and benefits and (ii) an increase in service supplies, offset by reduced
costs in equipment maintenance.

Equipment leases and depreciation and amortization increased approximately $1.1
million, or approximately 15.6%, for the three months ended December 31, 1997,
compared to the same period in 1996.  The increase was due primarily to the
acquisitions discussed above (approximately $0.7 million) and an increase in
costs at existing facilities (approximately $0.4 million).  The increase at
existing facilities was primarily due to the Company upgrading its existing
diagnostic medical equipment.

GROSS PROFIT:  Gross profit increased approximately $2.1 million during the
three months ended December 31, 1997, compared to the same period in 1996.  The
increase was due to the acquisitions discussed above (approximately $1.4
million), and an increase at existing facilities (approximately $0.7 million).

CORPORATE OPERATING EXPENSES:  Corporate operating expenses increased
approximately $0.1 million for the three months ended December 31, 1997,
compared to the same period in 1996.  The increase was primarily due to
additional consulting and travel costs associated with the Company's acquisition
activities. 

PROVISION FOR SUPPLEMENTAL SERVICE FEE TERMINATION:  As part of the 
Recapitalization and Bank Financing discussed below, the Company issued to GE 
7,000 shares of Series C Preferred Stock to terminate GE's rights to receive 
supplemental service fee payments equal to 14% of InSight's pre-tax income.  
The Series C Preferred Stock was valued at $7.0 million and the Company 
recorded a one-time provision of approximately $6.3 million , net of amounts 
previously accrued, for the Preferred Stock issuance.

INTEREST EXPENSE, NET:   Interest expense, net increased approximately $0.6 
million for the three months ended December 31, 1997, compared to the same 
period in 1996.  The increase was due primarily to additional debt related to 
the acquisitions discussed above (approximately $0.8 million) and additional 
debt related to the Company upgrading its existing diagnostic medical 
equipment, offset by reduced interest as a result of (i) the reduction in 
interest rate and the extinguishment of approximately $23 million in 
long-term debt as a result of the Recapitalization and Bank Financing 
discussed below (approximately $0.5 million), and (ii) amortization of 
long-term debt.

PROVISION FOR INCOME TAXES:  During the three months ended December 31, 1997,
the Company did not record a provision for income taxes due to the loss
resulting from the provision for supplemental service fee termination.

                                       15
<PAGE>

INCOME (LOSS) PER COMMON SHARE:  On a basic and diluted basis, net income 
(loss) per common share was ($0.53) for the three months ended December 31, 
1997, compared to net income per common share of $0.05 for the same period in 
1996. Excluding the one-time provision for supplemental service fee 
termination, net income per common share on a diluted basis would have been 
$0.21.  The improvement in net income per common share before the provision 
for supplemental service fee termination is the result of (i) increased gross 
profit, (ii) an increase in earnings from unconsolidated partnerships, and 
(iii) a reduction in the provision for income taxes offset by (i) increased 
corporate operating expenses and (ii) increased interest expense.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

InSight operates in a capital intensive, high fixed cost industry that requires
significant amounts of working capital to fund operations, particularly the
initial start-up and development expenses of new operations, and yet is
constantly under external pressure to contain costs and reduce prices.  Revenues
and cash flows have been adversely affected by an increased collection cycle,
competitive pressures and major restructurings within the health care industry. 
This adverse effect on revenues and cash flow is expected to continue,
especially in the mobile diagnostic imaging business.  Management believes that
InSight's long-term success is based upon its ability to successfully execute
its five interrelated strategic initiatives.

InSight continues to pursue acquisition opportunities.  InSight believes that
the expansion of its business through acquisitions is a key factor in achieving
and maintaining profitability.  Generally, acquisition opportunities are aimed
at increasing revenues and profits, and maximizing utilization of existing
capacity.  Incremental operating profit resulting from future acquisitions will
vary depending on geographic location, whether facilities are Mobile or Fixed,
the range of services provided and the Company's ability to integrate the
acquired businesses into its existing infrastructure.  Since the Merger, InSight
has completed six acquisitions, as discussed above.

The Company consummated the Recapitalization on October 14, 1997 pursuant to 
which (a) the Company issued to Carlyle 25,000 shares of Series B Preferred 
Stock having a liquidation preference of $1,000 per share and warrants to 
purchase 250,000 shares of InSight Common Stock at the current exercise price 
of $10.00 per share, generating net proceeds to the Company (after related 
transaction costs of approximately $2.0 million) of approximately $23.0 
million; (b) the Company issued to GE 7,000 shares of Series C Preferred 
Stock, with a liquidation preference of $1,000 per share, in consideration of 
the termination of GE's right to receive supplemental service fee payments 
equal to 14% of InSight's pre-tax income, and issued to GE an additional 
20,953 shares of Series C Preferred Stock in exchange for all of GE's shares 
of Series A Preferred Stock; and (c) the Company executed a Credit Agreement 
with NationsBank which, was consummated October 22, 1997 and included, (i) a 
$50 million term loan facility consisting of a $20 million tranche with 
increasing amortization over a five-year period and a $30 million tranche 
with increasing amortization over a seven-year period principally repayable 
in years 6 and 7, (ii) a $25 million revolving working capital facility with 
a five-year maturity, and (iii) a $50 million acquisition facility, which was 
increased by an additional $25 million on December 19, 1997.  The net 
proceeds from the Carlyle investment were used to refinance a portion of the 
outstanding GE indebtedness (approximately $23 million).  At the initial 
funding of the Bank Financing, all of the term loan facility was drawn down 
to refinance all of the remaining GE indebtedness (approximately $47 million) 
and approximately $10 million of the revolving facility was drawn down for 
working capital purposes.

InSight's operations are principally dependent on its ability (either directly
or indirectly through its hospital customers) to attract referrals from
physicians and other health care providers representing a variety of
specialties.  The Company's eligibility to provide service in response to a
referral is often dependent on the existence of a contractual arrangement with
the referred patient's insurance carrier (primarily if the insurance is provided
by a managed care organization).  Managed care contracting has become very
competitive and reimbursement schedules are nearing Medicare reimbursement
levels. 

In connection with the Merger, certain financial accommodations with GE became
effective in June 1996.  The GE indebtedness was repaid in full from the
proceeds of the Carlyle investment and the Bank Financing.  The terms of the
Series B Preferred Stock and the Series C Preferred Stock, as well as the Bank
Financing, contain certain restrictions on InSight's ability to act without
first obtaining a waiver or consent from Carlyle, GE and NationsBank.

Working capital increased to approximately $13.1 million at December 31, 1997
from a deficit of approximately $5.7 million at June 30, 1997.  This increase in
working capital of approximately $18.8 million is primarily due to


                                       16
<PAGE>

(i) net income before depreciation and amortization, (ii) the repayment of 
approximately $23.0 million in long-term debt, and (iii) and the 
reclassification of the current portion of debt to long-term debt as a result 
of the Bank Financing, offset by the current portion of additional debt 
incurred as a result of the Company's acquisition strategy discussed above 
and principal payments on long-term debt.   As part of the Bank Financing, 
the Company has a $25 million working capital facility, of which $14 million 
was available to the Company as of December 31, 1997.

Cash and cash equivalents increased to approximately $11.8 million at December
31, 1997 from approximately $7.1 million at June 30, 1997.  This increase of
approximately $4.7 million resulted primarily from (i) net income before
depreciation, amortization and provision for supplemental service fee
(approximately $8.4 million), (ii) proceeds from issuance of preferred stock
(approximately $23.3 million), (iii) proceeds from issuance of debt, net of loan
fees (approximately $80.9 million), and (iv) an increase in accounts payable and
other current liabilities.  The increase was offset by (i) payments on long-term
debt (approximately $78.4 million), (ii) additions to property and equipment
(approximately $13.5 million), (iii) acquisitions of imaging centers
(approximately $12.9 million), and (iv) an increase in receivables and other
current assets.

The Company has committed to purchase, at an aggregate cost of approximately 
$5.6 million, three MRI systems for delivery during the quarter ending March 
31, 1998. The Bank Financing may be used to finance the purchase of such 
equipment. In addition, the Company has committed to purchase or lease from 
GE, at an aggregate cost of approximately $24 million, including siting 
costs, 20 open MRI systems for delivery and installation over the next two 
years.  The Company may purchase, lease or upgrade other MRI systems as 
opportunities arise to place new equipment into service when new contract 
services agreements are signed, existing agreements are renewed, acquisitions 
are completed, or new imaging centers are developed in accordance with the 
Company's strategic initiatives.  As of December 31, 1997, the Company has 
installed three of the open MRI systems.

The Company has assessed and continues to assess the impact of the Year 2000
Issue on its reporting systems and operations.  The Year 2000 Issue exists
because many computer systems and applications currently use two-digit date
fields to designate a year.  As the century date occurs, date sensitive systems
may recognize the Year 2000 as 1900 or not at all.  This inability to recognize
or properly treat Year 2000 may cause the Company's systems to process critical
financial and operational information incorrectly.  The Company has developed a
plan to modify existing computer systems and applications, but the Company has
not determined the final amounts necessary to modify existing computer systems
and applications.  If the Company's remediation plan is not successful, there
could be a significant disruption of the Company's ability to transact business
with its customers and suppliers.

Certain statements contained in this report are forward-looking statements that
involve a number of risks and uncertainties. The factors that could cause actual
results to differ materially include the following: availability of financing;
limitations and delays in reimbursement by third-party payors; contract renewals
and financial stability of customers; technology changes; governmental
regulation; conditions within the health care environment; adverse utilization
trends for certain diagnostic imaging procedures; aggressive competition;
general economic factors; InSight's inability to carry out its business strategy
due to rising purchase prices of imaging centers and companies; and the risk
factors listed from time to time in InSight's filings with the Securities and
Exchange Commission ("SEC").

     Commitment Percentage of the Revolving Committed Amount and in 
     substantially the form of EXHIBIT 2.1(e).

          2.2  LETTER OF CREDIT SUBFACILITY.

          (a)  ISSUANCE.  Subject to the terms and conditions hereof and of 
     the LOC Documents, if any, and any other terms and conditions which the 
     Issuing Lender may reasonably require and in reliance upon the 
     representations and warranties set forth herein, the Issuing Lender 
     agrees to issue, and each Lender severally agrees to participate in the 
     issuance by the Issuing Lender of, standby and trade Letters of Credit 
     in Dollars from time to time from the Effective Date until the date five 
     (5) days prior to the Maturity Date as the Borrower may request, in a 
     form acceptable to the Issuing Lender; PROVIDED, HOWEVER, that (i) the 
     LOC Obligations outstanding shall not at any time exceed EIGHT MILLION 
     DOLLARS ($8,000,000) (the "LOC COMMITTED AMOUNT") and (ii) the sum of 
     the aggregate principal amount of outstanding Revolving Loans PLUS LOC 
     Obligations outstanding shall not at any time exceed the Revolving 
     Committed Amount. No Letter of Credit shall (x) have an original expiry 
     date more than one year from the date of issuance or (y) as originally 
     issued or as extended, have an expiry date extending beyond the Maturity 
     Date.  Each Letter of Credit shall comply with the related LOC 
     Documents.  The issuance and expiry dates of each Letter of Credit shall 
     be a Business Day.

          (b)  NOTICE AND REPORTS.  The request for the issuance of a Letter 
     of Credit shall be submitted by the Borrower to the Issuing Lender at 
     least three (3) Business Days prior to the requested date of issuance. 
     The Issuing Lender will, at least quarterly and more frequently upon 
     request, disseminate to each of the Lenders a detailed report specifying 
     the Letters of Credit which are then issued and outstanding and any 
     activity with respect thereto which may have occurred since the date of 
     the prior report, and including therein, among other things, the 
     beneficiary, the face amount and the expiry date, as well as any payment 
     or expirations which may have occurred.

          (c)  PARTICIPATION.  Each Lender, upon issuance of a Letter
     of Credit, shall be deemed to have purchased without recourse a
     Participation Interest from the applicable Issuing Lender in such Letter
     of Credit and the obligations arising thereunder and any collateral
     relating thereto, in each case in an amount equal to its pro rata share
     of the obligations under such Letter of Credit (based on the respective
     Revolving Commitment Percentages of the Lenders) and shall absolutely,
     unconditionally and irrevocably assume and be obligated to pay to the
     Issuing Lender and discharge when due, its pro rata share of the
     obligations arising under such Letter of Credit.  Without limiting the
     scope and nature of each Lender's Participation Interest in any Letter
     of Credit, to the extent that the Issuing Lender has not been reimbursed
     as required hereunder or under any such Letter of Credit, each such
     Lender shall pay to the Issuing Lender its pro rata share of such
     unreimbursed drawing in same day funds on the day of notification by the
     Issuing Lender of an unreimbursed drawing pursuant to the provisions of
     subsection (d) below.  The obligation of each Lender to so reimburse the
     Issuing Lender shall be absolute and unconditional and shall not be
     affected by the occurrence of a Default, an Event of Default or any
     other occurrence or event.  Any such reimbursement shall not relieve or
     otherwise impair the obligation of the Borrower to reimburse the Issuing
     Lender under any Letter of Credit, together with interest as hereinafter
     provided.

          (d)  REIMBURSEMENT.  In the event of any drawing under any
     Letter of Credit, the Issuing Lender will promptly notify the Borrower.
     Unless the Borrower shall immediately notify the Issuing Lender that the
     Borrower intends to otherwise reimburse the Issuing Lender for such
     drawing, the Borrower shall be deemed to have requested that the Lenders
     make a Revolving Loan in the amount of the drawing as provided in
     subsection (e) below on the related Letter of Credit, the proceeds of
     which will be used to satisfy the related reimbursement obligations.
     The Borrower promises to reimburse the Issuing Lender on the day of
     drawing under any Letter of Credit (either with the proceeds of a
     Revolving Loan obtained hereunder or otherwise) in same day funds.  If
     the Borrower shall fail to reimburse the Issuing Lender as provided
     hereinabove, the unreimbursed amount of such drawing shall bear interest
     at a per annum rate equal to the Adjusted Base Rate PLUS 2%.  The
     Borrower's reimbursement obligations hereunder shall be absolute and
     unconditional under all circumstances irrespective of any rights of
     setoff, counterclaim or defense to payment the Borrower may claim or
     have against the Issuing Lender, the Agent, the Lenders, the beneficiary
     of the Letter of Credit drawn upon or any other Person, including
     without limitation any defense based on any failure of the Borrower or
     any other Credit Party to receive consideration or the legality,
     validity, regularity or unenforceability of the Letter of Credit.  The
     Issuing Lender will promptly notify the other Lenders of the amount of
     any unreimbursed drawing and each Lender shall promptly pay to the Agent
     for the account of the Issuing Lender in Dollars and in immediately
     available funds, the amount of such Lender's pro rata share of such
     unreimbursed drawing.  Such payment shall be made on the day such notice
     is received by such Lender from the Issuing Lender if such notice is
     received at or before 2:00 P.M. (Charlotte, North Carolina time)
     otherwise such payment shall be made at or before 12:00 Noon (Charlotte,
     North Carolina time) on the Business Day next succeeding the day such
     notice is received.  If such Lender does not pay such amount to the
     Issuing Lender in full upon such request, such Lender shall, on demand,
     pay to the Agent for the account of the Issuing Lender interest on the
     unpaid amount during the

                                      34

<PAGE>

     period from the date of such drawing until such Lender pays such amount
     to the Issuing Lender in full at a rate per annum equal to, if paid
     within two (2) Business Days of the date that such Lender is required to
     make payments of such amount pursuant to the preceding sentence, the
     Federal Funds Rate and thereafter at a rate equal to the Base Rate.
     Each Lender's obligation to make such payment to the Issuing Lender, and
     the right of the Issuing Lender to receive the same, shall be absolute
     and unconditional, shall not be affected by any circumstance whatsoever
     and without regard to the termination of this Credit Agreement or the
     Commitments hereunder, the existence of a Default or Event of Default or
     the acceleration of the obligations of the Borrower hereunder and shall
     be made without any offset, abatement, withholding or reduction
     whatsoever.  Simultaneously with the making of each such payment by a
     Lender to the Issuing Lender, such Lender shall, automatically and
     without any further action on the part of the Issuing Lender or such
     Lender, acquire a Participation Interest in an amount equal to such
     payment (excluding the portion of such payment constituting interest
     owing to the Issuing Lender) in the related unreimbursed drawing portion
     of the LOC Obligation and in the interest thereon and in the related LOC
     Documents, and shall have a claim against the Borrower with respect
     thereto.

          (e)  REPAYMENT WITH REVOLVING LOANS.  On any day on which
     the Borrower shall have requested, or been deemed to have requested, a
     Revolving Loan advance to reimburse a drawing under a Letter of Credit,
     the Agent shall give notice to the Lenders that a Revolving Loan has
     been requested or deemed requested by the Borrower to be made in
     connection with a drawing under a Letter of Credit, in which case a
     Revolving Loan advance comprised of Base Rate Loans (or Eurodollar Loans
     to the extent the Borrower has complied with the procedures of Section
     2.1(b)(i) with respect thereto) shall be immediately made to the
     Borrower by all Lenders (notwithstanding any termination of the
     Commitments pursuant to Section 9.2) PRO RATA based on the respective
     Revolving Commitment Percentages of the Lenders (determined before
     giving effect to any termination of the Commitments pursuant to Section
     9.2) and the proceeds thereof shall be paid directly to the Issuing
     Lender for application to the respective LOC Obligations.  Each such
     Lender hereby irrevocably agrees to make its pro rata share of each such
     Revolving Loan immediately upon any such request or deemed request in
     the amount, in the manner and on the date specified in the preceding
     sentence NOTWITHSTANDING (i) the amount of such borrowing may not comply
     with the minimum amount for advances of Revolving Loans otherwise
     required hereunder, (ii) whether any conditions specified in Section 5.3
     are then satisfied, (iii) whether a Default or an Event of Default then
     exists, (iv) failure for any such request or deemed request for
     Revolving Loan to be made by the time otherwise required hereunder, (v)
     whether the date of such borrowing is a date on which Revolving Loans
     are otherwise permitted to be made hereunder or (vi) any termination of
     the Commitments relating thereto immediately prior to or
     contemporaneously with such borrowing.  In the event that any Revolving
     Loan cannot for any reason be made on the date otherwise required above
     (including, without limitation, as a result of the commencement of a
     proceeding under the Bankruptcy Code with respect to the Borrower or any
     Credit Party), then each such Lender hereby agrees that it shall
     forthwith purchase (as of the date such borrowing would otherwise have
     occurred, but adjusted for any payments received from the Borrower on or
     after such date and prior to such purchase) from the Issuing Lender such
     Participation Interests in the outstanding LOC Obligations as shall be
     necessary to cause each such

                                      35


<PAGE>

     Lender to share in such LOC Obligations ratably (based upon the
     respective Revolving Commitment Percentages of the Lenders (determined
     before giving effect to any termination of the Commitments pursuant to
     Section 9.2)), PROVIDED that at the time any purchase of Participation
     Interests pursuant to this sentence is actually made, the purchasing
     Lender shall be required to pay to the Issuing Lender, to the extent not
     paid to the Issuer by the Borrower in accordance with the terms of
     subsection (d) above, interest on the principal amount of Participation
     Interests purchased for each day from and including the day upon which
     such borrowing would otherwise have occurred to but excluding the date
     of payment for such Participation Interests, at the rate equal to, if
     paid within two (2) Business Days of the date of the Revolving Loan
     advance, the Federal Funds Rate, and thereafter at a rate equal to the
     Base Rate.

          (f)  DESIGNATION OF CONSOLIDATED PARTIES AS ACCOUNT PARTIES.
     Notwithstanding anything to the contrary set forth in this Credit
     Agreement, including without limitation Section 2.2(a), a Letter of
     Credit issued hereunder may contain a statement to the effect that such
     Letter of Credit is issued for the account of a Consolidated Party other
     than the Borrower, provided that notwithstanding such statement, the
     Borrower shall be the actual account party for all purposes of this
     Credit Agreement for such Letter of Credit and such statement shall not
     affect the Borrower's reimbursement obligations hereunder with respect
     to such Letter of Credit.

          (g)  RENEWAL, EXTENSION.  The renewal or extension of any
     Letter of Credit shall, for purposes hereof, be treated in all respects
     the same as the issuance of a new Letter of Credit hereunder.

          (h)  UNIFORM CUSTOMS AND PRACTICES.  The Issuing Lender may
     have the Letters of Credit be subject to The Uniform Customs and
     Practice for Documentary Credits, as published as of the date of issue
     by the International Chamber of Commerce (the "UCP"), in which case the
     UCP may be incorporated therein and deemed in all respects to be a part
     thereof.

          (i)  INDEMNIFICATION; NATURE OF ISSUING LENDER'S DUTIES.

               (i)     In addition to its other obligations under this
          Section 2.2, the Borrower hereby agrees to pay, and protect,
          indemnify and save each Lender harmless from and against, any and
          all claims, demands, liabilities, damages, losses, costs, charges
          and expenses (including reasonable attorneys' fees) that such
          Lender may incur or be subject to as a consequence, direct or
          indirect, of (A) the issuance of any Letter of Credit or (B) the
          failure of such Lender to honor a drawing under a Letter of Credit
          as a result of any act or omission, whether rightful or wrongful,
          of any present or future de jure or de facto government or
          Governmental Authority (all such acts or omissions, herein called
          "Government Acts").

               (ii)    As between the Borrower and the Lenders
          (including the Issuing Lender), the Borrower shall assume all risks
          of the acts, omissions or misuse of any Letter of Credit by the
          beneficiary thereof.  No Lender (including the Issuing

                                      36


<PAGE>

          Lender) shall be responsible:  (A) for the form, validity,
          sufficiency, accuracy, genuineness or legal effect of any document
          submitted by any party in connection with the application for and
          issuance of any Letter of Credit, even if it should in fact prove to
          be in any or all respects invalid, insufficient, inaccurate,
          fraudulent or forged; (B) for the validity or sufficiency of any
          instrument transferring or assigning or purporting to transfer or
          assign any Letter of Credit or the rights or benefits thereunder or
          proceeds thereof, in whole or in part, that may prove to be invalid
          or ineffective for any reason; (C) for errors, omissions,
          interruptions or delays in transmission or delivery of any messages,
          by mail, cable, telegraph, telex or otherwise, whether or not they
          be in cipher; (D) for any loss or delay in the transmission or
          otherwise of any document required in order to make a drawing under
          a Letter of Credit or of the proceeds thereof; and (E) for any
          consequences arising from causes beyond the control of such Lender,
          including, without limitation, any Government Acts.  None of the above
          shall affect, impair, or prevent the vesting of the Issuing Lender's
          rights or powers hereunder.

               (iii)   In furtherance and extension and not in
          limitation of the specific provisions hereinabove set forth, any
          action taken or omitted by any Lender (including the Issuing
          Lender), under or in connection with any Letter of Credit or the
          related certificates, if taken or omitted in good faith, shall not
          put such Lender under any resulting liability to the Borrower or
          any other Credit Party.  It is the intention of the parties that
          this Credit Agreement shall be construed and applied to protect and
          indemnify each Lender (including the Issuing Lender) against any
          and all risks involved in the issuance of the Letters of Credit,
          all of which risks are hereby assumed by the Borrower (on behalf of
          itself and each of the other Credit Parties), including, without
          limitation, any and all Government Acts.  No Lender (including the
          Issuing Lender) shall, in any way, be liable for any failure by
          such Lender or anyone else to pay any drawing under any Letter of
          Credit as a result of any Government Acts or any other cause beyond
          the control of such Lender.

               (iv)    Nothing in this subsection (h) is intended to
          limit the reimbursement obligations of the Borrower contained in
          subsection (d) above.  The obligations of the Borrower under this
          subsection (h) shall survive the termination of this Credit
          Agreement. No act or omissions of any current or prior beneficiary
          of a Letter of Credit shall in any way affect or impair the rights
          of the Lenders (including the Issuing Lender) to enforce any right,
          power or benefit under this Credit Agreement.

               (v)     Notwithstanding anything to the contrary
          contained in this subsection (h), the Borrower shall have no
          obligation to indemnify any Lender (including the Issuing Lender)
          in respect of any liability incurred by such Lender (A) arising
          solely out of the gross negligence or willful misconduct of such
          Lender, as determined by a court of competent jurisdiction, or (B)
          caused by such Lender's failure to pay under any Letter of Credit
          after presentation to it of a request strictly complying with the
          terms and conditions of such Letter of Credit, as determined by a
          court of competent jurisdiction, unless such payment is prohibited
          by any law, regulation, court order or decree.

                                      37


<PAGE>

          (j)  RESPONSIBILITY OF ISSUING LENDER. It is expressly
     understood and agreed that the obligations of the Issuing Lender
     hereunder to the Lenders are only those expressly set forth in this
     Credit Agreement and that the Issuing Lender shall be entitled to assume
     that the conditions precedent set forth in Section 5.3 have been
     satisfied unless it shall have acquired actual knowledge that any such
     condition precedent has not been satisfied; PROVIDED, HOWEVER, that
     nothing set forth in this Section 2.2 shall be deemed to prejudice the
     right of any Lender to recover from the Issuing Lender any amounts made
     available by such Lender to the Issuing Lender pursuant to this Section
     2.2 in the event that it is determined by a court of competent
     jurisdiction that the payment with respect to a Letter of Credit
     constituted gross negligence or willful misconduct on the part of the
     Issuing Lender.

          (k)  CONFLICT WITH LOC DOCUMENTS.  In the event of any
     conflict between this Credit Agreement and any LOC Document (including
     any letter of credit application), this Credit Agreement shall control.

               2.3     ACQUISITION LOANS.

          (a)  ACQUISITION LOAN COMMITMENT.  Subject to the terms and
     conditions hereof and in reliance upon the representations and
     warranties set forth herein, each Lender severally agrees to make
     available to the Borrower such Lender's Acquisition Loan Commitment
     Percentage of revolving credit loans requested by the Borrower in
     Dollars ("ACQUISITION LOANS") from time to time from the Effective Date
     until October 14, 1999, or such earlier date as the Acquisition Loan
     Commitments shall have been terminated as provided herein for the
     purpose of financing the purchase price of, and fees and expenses in
     connection with, Permitted Acquisitions and Permitted Capital
     Expenditures; PROVIDED, HOWEVER, that the sum of the aggregate principal
     amount of outstanding Acquisition Loans shall not exceed FIFTY MILLION
     DOLLARS ($50,000,000) (as such aggregate maximum amount may be reduced
     or increased from time to time as provided in Section 3.4, the
     "ACQUISITION LOAN COMMITTED AMOUNT"); PROVIDED, FURTHER, (A) with regard
     to each Lender individually, such Lender's outstanding Acquisition Loans
     shall not exceed such Lender's Acquisition Loan Commitment Percentage of
     the Acquisition Loan Committed Amount, and (B) the aggregate principal
     amount of outstanding Acquisition Loans shall not exceed the Acquisition
     Loan Committed Amount.  Acquisition Loans may consist of Base Rate Loans
     or Eurodollar Loans, or a combination thereof, as the Borrower may
     request; PROVIDED, HOWEVER, that no more than 16 Eurodollar Loans shall
     be outstanding hereunder at any time.  For purposes hereof, Eurodollar
     Loans with different Interest Periods shall be considered as separate
     Eurodollar Loans, even if they begin on the same date, although
     borrowings, extensions and conversions may, in accordance with the
     provisions hereof, be combined at the end of existing Interest Periods
     to constitute a new Eurodollar Loan with a single Interest Period.
     Acquisition Loans hereunder may be repaid and reborrowed in accordance
     with the provisions hereof.

                                      38

<PAGE>

     (b)  ACQUISITION LOAN BORROWINGS.

          (i)  NOTICE OF BORROWING.  The Borrower shall request an
     Acquisition Loan borrowing by written notice (or telephonic notice
     promptly confirmed in writing) to the Agent not later than 12:00 Noon
     (Charlotte, North Carolina time) on the Business Day prior to the date
     of the requested borrowing in the case of Base Rate Loans, and on the
     third Business Day prior to the date of the requested borrowing in the
     case of Eurodollar Loans.  Each such request for borrowing shall (A) be
     irrevocable, (B) specify (1) that an Acquisition Loan is requested, (2)
     the date of the requested borrowing (which shall be a Business Day), (3)
     the aggregate principal amount to be borrowed, (4) whether the borrowing
     shall be comprised of Base Rate Loans, Eurodollar Loans or a combination
     thereof, and if Eurodollar Loans are requested, the Interest Period(s)
     therefor and (C) be accompanied by a certificate of the chief financial
     of the Borrower describing in reasonable detail the Permitted
     Acquisition to which such requested borrowing relates.  If the Borrower
     shall fail to specify in any such Notice of Borrowing (I) an applicable
     Interest Period in the case of a Eurodollar Loan, then such notice shall
     be deemed to be a request for an Interest Period of one month, or (II)
     the type of Acquisition Loan requested, then such notice shall be deemed
     to be a request for a Base Rate Loan hereunder.  The Agent shall give
     notice to each affected Lender promptly upon receipt of each Notice of
     Borrowing pursuant to this Section 2.3(b)(i), the contents thereof and
     each such Lender's share of any borrowing to be made pursuant thereto.

          (ii) MINIMUM AMOUNTS.  Each Eurodollar Loan or Base Rate
     Loan that is an Acquisition Loan shall be in a minimum aggregate
     principal amount of $1,000,000 and integral multiples of $100,000 in
     excess thereof (or the remaining amount of the Acquisition Loan
     Committed Amount, if less).

          (iii) ADVANCES.  Each Lender will make its Acquisition Loan
     Commitment Percentage of each Acquisition Loan borrowing available to
     the Agent for the account of the Borrower as specified in SECTION
     3.15(a), or in such other manner as the Agent may specify in writing, by
     2:00 P.M. (Charlotte, North Carolina time) on the date specified in the
     applicable Notice of Borrowing in Dollars and in funds immediately
     available to the Agent.  Such borrowing will then be made available to
     the Borrower by the Agent by 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.

     (c)  REPAYMENT.

          (i)  The principal amount of all Acquisition Loans advanced
     during the period from the Effective Date to and including October 14,
     1998 shall be repaid in twenty (20) consecutive quarterly installments
     as follows, unless accelerated sooner pursuant to Section 9.2:

SECTION 3

     OTHER PROVISIONS RELATING TO CREDIT FACILITIES

          3.1  DEFAULT RATE.

     Upon the occurrence, and during the continuance, of an Event of Default,
the principal of and, to the extent permitted by law, interest on the Loans and
any other amounts owing hereunder or under the other Credit Documents shall bear
interest, payable on demand, at a per annum rate 2% greater than the rate which
would otherwise be applicable (or if no rate is applicable, whether in respect
of interest, fees or other amounts, then the Adjusted Base Rate PLUS 2%).

          3.2  EXTENSION AND CONVERSION.

     Subject to the terms of Section 5.3, the Borrower shall have the option, on
any Business Day, to extend existing Loans into a subsequent permissible
Interest Period or to convert Loans into Loans of another interest rate type;
PROVIDED, HOWEVER, that (i) except as provided in Section 3.8, Eurodollar Loans
may be converted into Base Rate Loans only on the last day of the Interest
Period applicable thereto, (ii) Eurodollar Loans may be extended, and Base Rate
Loans may be converted into Eurodollar Loans, only if no Default or Event of
Default is in existence on the date of extension or conversion, (iii) Loans
extended as, or converted into, Eurodollar Loans shall be subject to the terms
of the definition of "INTEREST PERIOD" set forth in Section 1.1 and shall be in
such minimum amounts as provided in, with respect to Revolving Loans, Section
2.1(b)(ii), with respect to Acquisition Loans, Section 2.3(b)(ii), with respect
to the Tranche A Term Loan, Section 2.4(c), or, with respect to the Tranche B
Term Loan, Section 2.5(c), (iv) no more than 16 Eurodollar Loans shall be
outstanding hereunder at any time (it being understood that, for purposes
hereof, Eurodollar Loans with different Interest Periods shall be considered as
separate Eurodollar Loans, even if they begin on the same date, although
borrowings, extensions and conversions may, in accordance with the provisions
hereof, be combined at the end of existing Interest Periods to constitute a new
Eurodollar Loan with a single Interest Period) and (v) any request for extension
or conversion of a Eurodollar Loan which shall fail to specify an Interest
Period shall be deemed to be a request for an Interest Period of one month.
Each such extension or conversion shall be effected by the Borrower by giving a
Notice of Extension/Conversion (or telephonic notice promptly confirmed in
writing) to the office of the Agent specified in specified in SCHEDULE 2.1(a),
or at such other office as the Agent may designate in writing, prior to 12:00
Noon (Charlotte, North Carolina time) on the Business Day of, in the case of the
conversion of a Eurodollar Loan into a Base Rate Loan, and on the third Business
Day prior to, in the case of the extension of a Eurodollar Loan as, or
conversion of a Base Rate Loan into, a Eurodollar Loan, the date of the proposed
extension or conversion, specifying the date of the proposed extension or
conversion, the Loans to be so extended or converted, the types of Loans into
which such Loans are to be converted and, if appropriate, the applicable
Interest Periods with respect thereto.  Each request for extension or conversion
shall be irrevocable and shall constitute a representation and warranty by the
Borrower of the matters specified in subsections (b), (c) and (d) of
Section 5.3.  In the event the Borrower fails to request extension or
conversion of any Eurodollar Loan in accordance with this Section, or any
such conversion or extension is not


                                      46

<PAGE>

permitted or required by this Section, then such Eurodollar Loan shall be
automatically converted into a Base Rate Loan at the end of the Interest
Period applicable thereto.  The Agent shall give each Lender notice as
promptly as practicable of any such proposed extension or conversion
affecting any Loan.

          3.3  PREPAYMENTS.

          (a)  VOLUNTARY PREPAYMENTS.  The Borrower shall have the
     right to prepay Loans in whole or in part from time to time, but
     otherwise without premium or penalty; PROVIDED, HOWEVER, that each
     partial prepayment of Loans shall be in a minimum principal amount of
     $2,500,000 and integral multiples of $500,000.  Subject to the foregoing
     terms, amounts prepaid under this Section 3.3(a) shall be applied as the
     Borrower may elect; PROVIDED that if the Borrower fails to specify a
     voluntary prepayment then such prepayment shall be applied first to
     Revolving Loans, second to the outstanding revolving loan portion of the
     Acquisition Loans and third pro rata to the outstanding term loan
     portion of the Acquisition Loans, the Tranche A Term Loan and the
     Tranche B Term Loan (in each case ratably to the remaining Principal
     Amortization Payments thereof), in each case first to Base Rate Loans
     and then to Eurodollar Loans in direct order of Interest Period
     maturities.  One or more holders of the Tranche B Term Loans may decline
     to accept a voluntary prepayment under this Sections 3.3(a) to the
     extent there are sufficient Tranche A Term Loans outstanding and/or
     outstandings under the term loan portion of the Acquisition Loans to be
     paid with such prepayment, in which case such declined prepayments shall
     be allocated pro rata among the outstanding term loan portion of the
     Acquisition Loans, the Tranche A Term Loans and the Tranche B Term Loans
     held by Lenders accepting such prepayment.  All prepayments under this
     Section 3.3(a) shall be subject to Section 3.12 and be accompanied by
     interest on the principal amount prepaid through the date of prepayment.

          (b)  MANDATORY PREPAYMENTS.

               (i)     REVOLVING COMMITTED AMOUNT.  If at any time, the
          sum of the aggregate principal amount of outstanding Revolving Loans
          PLUS LOC Obligations outstanding shall exceed the Revolving Committed
          Amount, the Borrower immediately shall prepay the Revolving Loans and
          (after all Revolving Loans have been repaid) cash collateralize the
          LOC Obligations, in an amount sufficient to eliminate such excess.

               (ii)    EXCESS CASH FLOW.  Within 90 days after the end
          of each fiscal year (commencing with the fiscal year ending June
          30, 1998), the Borrower shall prepay the Loans in an amount equal
          to (w) 50% of the Excess Cash Flow earned during such prior fiscal
          year LESS (x) the amount of any voluntary prepayments of the
          Tranche A Term Loan, the Tranche B Term Loan, (to the extent
          accompanied by a reduction in the Revolving Committed Amount) the
          Revolving Loans or (to the extent accompanied by a reduction in the
          Acquisition Loan Committed Amount) the Acquisition Loans pursuant
          to Section 3.3(a) during such prior fiscal year LESS (z) the amount
          of any mandatory prepayments of the Tranche A Term Loan, the

                                      47
<PAGE>

          Tranche B Term Loan, (to the extent accompanied by a reduction in the
          Revolving Committed Amount) the Revolving Loans or (to the extent
          accompanied by a reduction in the Acquisition Loan Committed Amount) 
          the Acquisition Loans pursuant to Section 3.3(b)(iii), (iv) or (v) 
          during such prior fiscal year.  Any payments of Excess Cash Flow 
          shall be applied as set forth in clause (vii) below.

               (iii)   ASSET DISPOSITIONS.  Immediately upon the 
          occurrence of any Asset Disposition Prepayment Event, the Borrower 
          shall prepay the Loans in an aggregate amount equal to 100% of the 
          Net Cash Proceeds of the related Asset Disposition not applied (or 
          caused to be applied) by the Consolidated Parties during the related

administration thereof in the interpretation or administration of, any
applicable law, rule or regulation regarding capital adequacy, or compliance by
such Lender with any request or directive regarding capital adequacy (whether or
not having the force of law) of any such authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on such
Lender's capital or assets as a consequence of its commitments or obligations
hereunder to a level below that which such Lender could have achieved but for
such adoption, effectiveness, change or compliance (taking into consideration
such Lender's policies with respect to capital adequacy), then, upon notice from
such Lender to the Borrower, the Borrower shall be obligated to pay to such
Lender such additional amount or amounts as will compensate such Lender for such
reduction.  Any Lender claiming compensation under this Section 3.6 shall
furnish to the Borrower and the Agent a statement setting forth in reasonable
detail the additional amount or amounts payable to it hereunder and the
calculations used to determine such amount or amounts, which statement shall be
conclusive and binding on the

<PAGE>

parties hereto in the absence of manifest error. In determining such amount, 
such Lender may use any reasonable averaging and attribution methods.

          3.7  LIMITATION ON EURODOLLAR LOANS.

     If on or prior to the first day of any Interest Period for any Eurodollar
Loan:

          (a)  the Agent determines (which determination shall be
     conclusive) that by reason of circumstances affecting the relevant market,
     adequate and reasonable means do not exist for ascertaining the Eurodollar
     Rate for such Interest Period; or

          (b)  the Required Lenders determine (which determination shall
     be conclusive) and notify the Agent that the Eurodollar Rate will not
     adequately and fairly reflect the cost to the Lenders of funding Eurodollar
     Loans for such Interest Period;

then the Agent shall give the Borrower prompt notice thereof, and so long as
such condition remains in effect, the Lenders shall be under no obligation to
make additional Eurodollar Loans, Continue Eurodollar Loans, or to Convert Base
Rate Loans into Eurodollar Loans and the Borrower shall, on the last day(s) of
the then current Interest Period(s) for the outstanding Eurodollar Loans, either
prepay such Eurodollar Loans or Convert such Eurodollar Loans into Base Rate
Loans in accordance with the terms of this Credit Agreement.

          3.8  ILLEGALITY.

     Notwithstanding any other provision of this Credit Agreement, in the event
that it becomes unlawful for any Lender or its Applicable Lending Office to
make, maintain, or fund Eurodollar Loans hereunder, then such Lender shall
promptly notify the Borrower thereof and such Lender's obligation to make or
Continue Eurodollar Loans and to Convert Base Rate Loans into Eurodollar Loans
shall be suspended until such time as such Lender may again make, maintain, and
fund Eurodollar Loans (in which case the provisions of Section 3.10 shall be
applicable).

          3.9  REQUIREMENTS OF LAW.

     (a)  If, after the date hereof, the adoption of any applicable law, rule,
or regulation, or any change in any applicable law, rule, or regulation, or any
change in the interpretation or administration thereof by any Governmental
Authority, central bank, or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
of any such Governmental Authority, central bank, or comparable agency:

               (i)     shall subject such Lender (or its Applicable
     Lending Office) to any tax, duty, or other charge with respect to any
     Eurodollar Loans, its Notes, or its obligation to make Eurodollar Loans, or
     change the basis of taxation of any amounts payable to such Lender (or its
     Applicable Lending Office) under this Credit Agreement or its Notes in

                                      54

<PAGE>

     respect of any Eurodollar Loans (other than taxes imposed on the overall
     net income of such Lender by the jurisdiction in which such Lender has its
     principal office or such Applicable Lending Office);

               (ii)    shall impose, modify, or deem applicable any
     reserve, special deposit, assessment, or similar requirement (other than
     the Eurodollar Reserve Requirement utilized in the determination of the
     Adjusted Eurodollar Rate) relating to any extensions of credit or other
     assets of, or any deposits with or other liabilities or commitments of,
     such Lender (or its Applicable Lending Office), including the Commitment of
     such Lender hereunder; or

               (iii)   shall impose on such Lender (or its Applicable
     Lending Office) or on the United States market for certificates of deposit
     or the London interbank market any other condition affecting this Credit
     Agreement or its Notes or any of such extensions of credit or liabilities
     or commitments;

and the result of any of the foregoing is to increase the cost to such Lender
(or its Applicable Lending Office) of making, Converting into, Continuing, or
maintaining any Eurodollar Loans or to reduce any sum received or receivable by
such Lender (or its Applicable Lending Office) under this Credit Agreement or
its Notes with respect to any Eurodollar Loans, then the Borrower shall pay to
such Lender on demand such amount or amounts as will compensate such Lender for
such increased cost or reduction.  If any Lender requests compensation by the
Borrower under this Section 3.9(a), the Borrower may, by notice to such Lender
(with a copy to the Agent), suspend the obligation of such Lender to make or
Continue Eurodollar Loans, or to Convert Base Rate Loans into Eurodollar Loans,
until the event or condition giving rise to such request ceases to be in effect
(in which case the provisions of Section 3.10 shall be applicable); PROVIDED
that such suspension shall not affect the right of such Lender to receive the
compensation so requested.

     (b)  Each Lender shall promptly notify the Borrower and the Agent of any
event of which it has knowledge, occurring after the date hereof, which will
entitle such Lender to compensation pursuant to this Section 3.9 and will
designate a different Applicable Lending Office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Lender, be otherwise disadvantageous to it.  Any Lender
claiming compensation under this Section 3.9 shall furnish to the Borrower and
the Agent a statement setting forth in reasonable detail the additional amount
or amounts payable to it hereunder and the calculations used to determine such
amount or amounts, which statement shall be conclusive and binding on the
parties hereto in the absence of manifest error.  In determining such amount,
such Lender may use any reasonable averaging and attribution methods.

          3.10 TREATMENT OF AFFECTED LOANS.

     If the obligation of any Lender to make any Eurodollar Loan or to Continue,
or to Convert Base Rate Loans into, Eurodollar Loans shall be suspended pursuant
to Section 3.8 or 3.9 hereof, such Lender's Eurodollar Loans shall be
automatically Converted into Base Rate Loans on the last day(s) of the then
current Interest Period(s) for such Eurodollar Loans (or, in the case of a
Conversion required by Section 3.8 hereof, on such earlier date as such Lender
may specify to the 

                                      55

<PAGE>

Borrower with a copy to the Agent) and, unless and until such Lender gives 
notice as provided below that the circumstances specified in Section 3.8 or 
3.9 hereof that gave rise to such Conversion no longer exist:

          (a)  to the extent that such Lender's Eurodollar Loans have been so
     Converted, all payments and prepayments of principal that would otherwise
     be applied to such Lender's Eurodollar Loans shall be applied instead to
     its Base Rate Loans; and

          (b)  all Loans that would otherwise be made or Continued by such
     Lender as Eurodollar Loans shall be made or Continued instead as Base Rate
     Loans, and all Base Rate Loans of such Lender that would otherwise be
     Converted into Eurodollar Loans shall remain as Base Rate Loans.

If such Lender gives notice to the Borrower (with a copy to the Agent) that the
circumstances specified in Section 3.8 or 3.9 hereof that gave rise to the
Conversion of such Lender's Eurodollar Loans pursuant to this Section 3.10 no
longer exist (which such Lender agrees to do promptly upon such circumstances
ceasing to exist) at a time when Eurodollar Loans made by other Lenders are
outstanding, such Lender's Base Rate Loans shall be automatically Converted, on
the first day(s) of the next succeeding Interest Period(s) for such outstanding
Eurodollar Loans, to the extent necessary so that, after giving effect thereto,
all Loans held by the Lenders holding Eurodollar Loans and by such Lender are
held pro rata (as to principal amounts, interest rate basis, and Interest
Periods) in accordance with their respective Commitments.   

          3.11 TAXES.

          (a)  Any and all payments by the Borrower to or for the 
     account of any Lender or the Agent hereunder or under any other Credit 
     Document shall be made free and clear of and without deduction for any 
     and all present or future taxes, duties, levies, imposts, deductions, 
     charges or withholdings, and all liabilities with respect thereto, 
     EXCLUDING, in the case of each Lender and the Agent, taxes imposed on 
     its income, and franchise taxes imposed on it, by the jurisdiction under 
     the laws of which such Lender (or its Applicable Lending Office) or the 
     Agent (as the case may be) is organized or any political subdivision 
     thereof (all such non-excluded taxes, duties, levies, imposts, 
     deductions, charges, withholdings, and liabilities being hereinafter 
     referred to as "TAXES").  If the Borrower shall be required by law to 
     deduct any Taxes from or in respect of any sum payable under this Credit 
     Agreement or any other Credit Document to any Lender or the Agent, (i) 
     the sum payable shall be increased as necessary so that after making all 
     required deductions (including deductions applicable to additional sums 
     payable under this Section 3.11) such Lender or the Agent receives an 
     amount equal to the sum it would have received had no such deductions 
     been made, (ii) the Borrower shall make such deductions, (iii) the 
     Borrower shall pay the full amount deducted to the relevant taxation 
     authority or other authority in accordance with applicable law, and (iv) 
     the Borrower shall furnish to the Agent, at its address referred to in 
     Section 11.1, the original or a certified copy of a receipt evidencing 
     payment thereof.

                                      56

<PAGE>

          (b)  In addition, the Borrower agrees to pay any and all
     present or future stamp or documentary taxes and any other excise or
     property taxes or charges or similar levies which arise from any payment
     made under this Credit Agreement or any other Credit Document or from the
     execution or delivery of, or otherwise with respect to, this Credit
     Agreement or any other Credit Document (hereinafter referred to as "OTHER
     TAXES").

          (c)  The Borrower agrees to indemnify each Lender and the
     Agent for the full amount of Taxes and Other Taxes (including, without
     limitation, any Taxes or Other Taxes imposed or asserted by any
     jurisdiction on amounts payable under this Section 3.11) paid by such
     Lender or the Agent (as the case may be) and any liability (including
     penalties, interest, and expenses) arising therefrom or with respect
     thereto.  
     
          (d)  Each Lender organized under the laws of a jurisdiction
     outside the United States, on or prior to the date of its execution and
     delivery of this Credit Agreement in the case of each Lender listed on the
     signature pages hereof and on or prior to the date on which it becomes a
     Lender in the case of each other Lender, and from time to time thereafter
     if requested in writing by the Borrower or the Agent (but only so long as
     such Lender remains lawfully able to do so), shall provide the Borrower and
     the Agent with (i) Internal Revenue Service Form 1001 or 4224, as
     appropriate, or any successor form prescribed by the Internal Revenue
     Service, certifying that such Lender is entitled to benefits under an
     income tax treaty to which the United States is a party which reduces the
     rate of withholding tax on payments of interest or certifying that the
     income receivable pursuant to this Credit Agreement is effectively
     connected with the conduct of a trade or business in the United States,
     (ii) Internal Revenue Service Form W-8 or W-9, as appropriate, or any
     successor form prescribed by the Internal Revenue Service, and (iii) any
     other form or certificate required by any taxing authority (including any
     certificate required by Sections 871(h) and 881(c) of the Internal Revenue
     Code), certifying that such Lender is entitled to an exemption from or a
     reduced rate of tax on payments pursuant to this Credit Agreement or any of
     the other Credit Documents.
     
          (e)  For any period with respect to which a Lender has failed
     to provide the Borrower and the Agent with the appropriate form pursuant to
     Section 3.11(d) (unless such failure is due to a change in treaty, law, or
     regulation occurring subsequent to the date on which a form originally was
     required to be provided), such Lender shall not be entitled to
     indemnification under Section 3.11(a) or 3.11(b) with respect to Taxes
     imposed by the United States; PROVIDED, HOWEVER, that should a Lender,
     which is otherwise exempt from or subject to a reduced rate of withholding
     tax, become subject to Taxes because of its failure to deliver a form
     required hereunder, the Borrower shall take such steps as such Lender shall
     reasonably request to assist such Lender to recover such Taxes.
     
          (f)  If the Borrower is required to pay additional amounts to
     or for the account of any Lender pursuant to this Section 3.11, then such
     Lender will agree to use reasonable efforts to change the jurisdiction of
     its Applicable Lending Office so as to eliminate or reduce any such
     additional payment which may thereafter accrue if such change, in the
     judgment of such Lender, is not otherwise disadvantageous to such Lender.

                                      57

<PAGE>

          (g)  Within thirty (30) days after the date of any payment of
     Taxes, the Borrower shall furnish to the Agent the original or a certified
     copy of a receipt evidencing such payment.

          (h)  Any Lender claiming compensation under this Section 3.11
     shall furnish to the Borrower and the Agent a statement setting forth in
     reasonable detail the additional amount or amounts payable to it hereunder
     and the calculations used to determine such amount or amounts, which
     statement shall be conclusive and binding on the parties hereto in the
     absence of manifest error.

          (i)  Without prejudice to the survival of any other agreement
     of the Borrower hereunder, the agreements and obligations of the Borrower
     contained in this Section 3.11 shall survive the repayment of the Loans,
     LOC Obligations and other obligations under the Credit Documents and the
     termination of the Commitments hereunder.

          3.12 COMPENSATION.

     Upon the request of any Lender, the Borrower shall pay to such Lender such
amount or amounts as shall be sufficient (in the reasonable opinion of such
Lender) to compensate it for any loss, cost, or expense (including loss of
anticipated profits) incurred by it as a result of:

          (a)  any payment, prepayment, or Conversion of a Eurodollar
     Loan for any reason (including, without limitation, the acceleration of the
     Loans pursuant to Section 9.2) on a date other than the last day of  the
     Interest Period for such Loan; or

          (b)  any failure by the Borrower for any reason (including,
     without limitation, the failure of any condition precedent specified in
     Section 5 to be satisfied) to borrow, Convert, Continue, or prepay a
     Eurodollar Loan on the date for such borrowing, Conversion, Continuation,
     or prepayment specified in the relevant notice of borrowing, prepayment,
     Continuation, or Conversion under this Credit Agreement. 

With respect to Eurodollar Loans, such indemnification may include an amount
equal to the excess, if any, of (a) the amount of interest which would have
accrued on the amount so prepaid, or not so borrowed, converted or continued,
for the period from the date of such prepayment or of such failure to borrow,
convert or continue to the last day of the applicable Interest Period (or, in
the case of a failure to borrow, convert or continue, the Interest Period that
would have commenced on the date of such failure) in each case at the applicable
rate of interest for such Eurodollar Loans provided for herein (excluding,
however, the Applicable Percentage included therein, if any) over (b) the amount
of interest (as reasonably determined by such Lender) which would have accrued
to such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank Eurodollar market.  The covenants of
the Borrower set forth in this Section 3.12 shall survive the repayment of the
Loans, LOC Obligations and other obligations under the Credit Documents and the
termination of the Commitments hereunder.

          3.13 PRO RATA TREATMENT.

     Except to the extent otherwise provided herein:

          (a)  LOANS.  Each Loan, each payment or (subject to the terms
     of Section 3.3) prepayment of principal of any Loan or reimbursement
     obligations arising from drawings under Letters of Credit, each payment of
     interest on the Loans or reimbursement obligations arising from drawings
     under Letters of Credit, each payment of Revolving Unused Fees, each
     payment of Acquisition Loan Unused Fees, each payment of the Standby Letter
     of Credit Fee, each payment of the Trade Letter of Credit Fee, each
     reduction of the Revolving Committed Amount and each conversion or
     extension of any Loan, shall be allocated pro rata among the Lenders in
     accordance with the respective principal amounts of their outstanding Loans
     and Participation Interests.

          (b)  ADVANCES.  No Lender shall be responsible for the failure
     or delay by any other Lender in its obligation to make its ratable share of
     a borrowing hereunder; PROVIDED, HOWEVER, that the failure of any Lender to
     fulfill its obligations hereunder shall not relieve any other Lender of its
     obligations hereunder.  Unless the Agent shall have been notified by any
     Lender prior to the date of any requested borrowing that such Lender does
     not intend to make available to the Agent its ratable share of such
     borrowing to be made on such date, the Agent may assume that such Lender
     has made such amount available to the Agent on the date of such borrowing,
     and the Agent in reliance upon such assumption, may (in its sole discretion
     but without any obligation to do so) make available to the Borrower a
     corresponding amount.  If such corresponding amount is not in fact made
     available to the Agent, the Agent shall be able to recover such
     corresponding amount from such Lender.  If such Lender does not pay such
     corresponding amount forthwith upon the Agent's demand therefor, the Agent
     will promptly notify the Borrower, and the Borrower shall immediately pay
     such corresponding amount to the Agent.  The Agent shall also be entitled
     to recover from the Lender or the Borrower, as the case may be, interest on
     such corresponding amount in respect of each day from the date such
     corresponding amount was made available by the Agent to the Borrower to the
     date such corresponding amount is recovered by the Agent at a per annum
     rate equal to (i) from the Borrower at the applicable rate for the
     applicable borrowing pursuant to the Notice of Borrowing and (ii) from a
     Lender at the Federal Funds Rate.  Nothing contained in this Section
     3.13(b) shall be deemed to constitute a waiver by the Borrower of its
     rights in respect of any claim for breach of contract relating to the
     wrongful failure (as determined by a court of competent jurisdiction) of
     any Lender to make any Loan on the date of the requested borrowing.

          3.14 SHARING OF PAYMENTS.

     The Lenders agree among themselves that, in the event that any Lender shall
obtain payment in respect of any Loan, LOC Obligations or any other obligation
owing to such Lender under this Credit Agreement through the exercise of a right
of setoff, banker's lien or counterclaim, or pursuant to a secured claim under
Section 506 of Title 11 of the United States Code or other security or interest
arising from, or in lieu of, such secured claim, received by such Lender under

                                      59

<PAGE>

any applicable bankruptcy, insolvency or other similar law or otherwise, or by
any other means, in excess of its pro rata share of such payment as provided for
in this Credit Agreement, such Lender shall promptly purchase from the other
Lenders a Participation Interest in such Loans, LOC Obligations and other
obligations in such amounts, and make such other adjustments from time to time,
as shall be equitable to the end that all Lenders share such payment in
accordance with their respective ratable shares as provided for in this Credit
Agreement.  The Lenders further agree among themselves that if payment to a
Lender obtained by such Lender through the exercise of a right of setoff,
banker's lien, counterclaim or other event as aforesaid shall be rescinded or
must otherwise be restored, each Lender which shall have shared the benefit of
such payment shall, by repurchase of a Participation Interest theretofore sold,
return its share of that benefit (together with its share of any accrued
interest payable with respect thereto) to each Lender whose payment shall have
been rescinded or otherwise restored.  The Borrower agrees that any Lender so
purchasing such a Participation Interest may, to the fullest extent permitted by
law, exercise all rights of payment, including setoff, banker's lien or
counterclaim, with respect to such Participation Interest as fully as if such
Lender were a holder of such Loan, LOC Obligations or other obligation in the
amount of such Participation Interest.  Except as otherwise expressly provided
in this Credit Agreement, if any Lender or the Agent shall fail to remit to the
Agent or any other Lender an amount payable by such Lender or the Agent to the
Agent or such other Lender pursuant to this Credit Agreement on the date when
such amount is due, such payments shall be made together with interest thereon
for each date from the date such amount is due until the date such amount is
paid to the Agent or such other Lender at a rate per annum equal to the Federal
Funds Rate.  If under any applicable bankruptcy, insolvency or other similar
law, any Lender receives a secured claim in lieu of a setoff to which this
Section 3.14 applies, such Lender shall, to the extent practicable, exercise its
rights in respect of such secured claim in a manner consistent with the rights
of the Lenders under this Section 3.14 to share in the benefits of any recovery
on such secured claim.

          3.15 PAYMENTS, COMPUTATIONS, ETC. 

          (a)  Except as otherwise specifically provided herein, all
     payments hereunder shall be made to the Agent in dollars in immediately
     available funds, without offset, deduction, counterclaim or withholding of
     any kind, at the Agent's office specified in SCHEDULE 2.1(a) not later than
     2:00 P.M. (Charlotte, North Carolina time) on the date when due.  Payments
     received after such time shall be deemed to have been received on the next
     succeeding Business Day.  The Agent may (but shall not be obligated to)
     debit the amount of any such payment which is not made by such time to any
     ordinary deposit account of the Borrower maintained with the Agent (with
     notice to the Borrower).  The Borrower shall, at the time it makes any
     payment under this Credit Agreement, specify to the Agent the Loans, LOC
     Obligations, Fees, interest or other amounts payable by the Borrower
     hereunder to which such payment is to be applied (and in the event that it
     fails so to specify, or if such application would be inconsistent with the
     terms hereof, the Agent shall distribute such payment to the Lenders in
     such manner as the Agent may determine to be appropriate in respect of
     obligations owing by the Borrower hereunder, subject to the terms of
     Section 3.13(a)).  The Agent will distribute such payments to such Lenders,
     if any such payment is received prior to 12:00 Noon (Charlotte, North
     Carolina time) on a Business Day in like funds as received prior to the end
     of such Business Day and otherwise the Agent will distribute such payment
     to such Lenders on the next succeeding Business Day.  Whenever 

                                      60

<PAGE>

     any payment hereunder shall be stated to be due on a day which is not a 
     Business Day, the due date thereof shall be extended to the next 
     succeeding Business Day (subject to accrual of interest and Fees for the 
     period of such extension), except that in the case of Eurodollar Loans, 
     if the extension would cause the payment to be made in the next 
     following calendar month, then such payment shall instead be made on the 
     next preceding Business Day.  Except as expressly provided otherwise 
     herein, all computations of interest and fees shall be made on the basis 
     of actual number of days elapsed over a year of 360 days, except with 
     respect to computation of interest on Base Rate Loans which (unless the 
     Base Rate is determined by reference to the Federal Funds Rate) shall be 
     calculated based on a year of 365 or 366 days, as appropriate.  Interest 
     shall accrue from and include the date of borrowing, but exclude the 
     date of payment.

          (b)  ALLOCATION OF PAYMENTS AFTER EVENT OF DEFAULT. 
     Notwithstanding any other provisions of this Credit Agreement to the
     contrary, after the occurrence and during the continuance of an Event of
     Default, all amounts collected or received by the Agent or any Lender on
     account of the Credit Party Obligations or any other amounts outstanding
     under any of the Credit Documents or in respect of the Collateral shall be
     paid over or delivered as follows:

          FIRST, to the payment of all reasonable out-of-pocket costs and
     expenses (including without limitation reasonable attorneys' fees) of the
     Agent in connection with enforcing the rights of the Lenders under the
     Credit Documents and any protective advances made by the Agent with respect
     to the Collateral under or pursuant to the terms of the Collateral
     Documents;

          SECOND, to payment of any fees owed to the Agent;

          THIRD, to the payment of all reasonable out-of-pocket costs and
     expenses (including without limitation, reasonable attorneys' fees) of each
     of the Lenders in connection with enforcing its rights under the Credit
     Documents or otherwise with respect to the Credit Party Obligations owing
     to such Lender;

          FOURTH, to the payment of all of the Credit Party Obligations
     consisting of accrued fees and interest;

          FIFTH, to the payment of the outstanding principal amount of the
     Credit Party Obligations (including the payment or cash collateralization
     of the outstanding LOC Obligations);

          SIXTH, to all other Credit Party Obligations and other obligations
     which shall have become due and payable under the Credit Documents or
     otherwise and not repaid pursuant to clauses "FIRST" through "FIFTH" above;
     and

          SEVENTH, to the payment of the surplus, if any, to whoever may be
     lawfully entitled to receive such surplus.

                                      61

<PAGE>

     In carrying out the foregoing, (i) amounts received shall be applied in the
     numerical order provided until exhausted prior to application to the next
     succeeding category; (ii) each of the Lenders shall receive an amount equal
     to its pro rata share (based on the proportion that the then outstanding
     Loans and LOC Obligations held by such Lender bears to the aggregate then
     outstanding Loans and LOC Obligations) of amounts available to be applied
     pursuant to clauses "THIRD", "FOURTH", "FIFTH" and "SIXTH" above; and
     (iii) to the extent that any amounts available for distribution pursuant to
     clause "FIFTH" above are attributable to the issued but undrawn amount of
     outstanding Letters of Credit, such amounts shall be held by the Agent in a
     cash collateral account and applied (A) first, to reimburse the Issuing
     Lender from time to time for any drawings under such Letters of Credit and
     (B) then, following the expiration of all Letters of Credit, to all other
     obligations of the types described in clauses "FIFTH" and "SIXTH" above in
     the manner provided in this Section 3.15(b).

          3.16 EVIDENCE OF DEBT.

          (a)  Each Lender shall maintain an account or accounts
     evidencing each Loan made by such Lender to the Borrower from time to time,
     including the amounts of principal and interest payable and paid to such
     Lender from time to time under this Credit Agreement.  Each Lender will
     make reasonable efforts to maintain the accuracy of its account or accounts
     and to promptly update its account or accounts from time to time, as
     necessary.

          (b)  The Agent shall maintain the Register pursuant to Section
     11.3(c), and a subaccount for each Lender, in which Register and
     subaccounts (taken together) shall be recorded (i) the amount, type and
     Interest Period of each such Loan hereunder, (ii) the amount of any
     principal or interest due and payable or to become due and payable to each
     Lender hereunder and (iii) the amount of any sum received by the Agent
     hereunder from or for the account of the Borrower and each Lender's share
     thereof.  The Agent will make reasonable efforts to maintain the accuracy
     of the subaccounts referred to in the preceding sentence and to promptly
     update such subaccounts from time to time, as necessary.

          (c)  The entries made in the accounts, Register and
     subaccounts maintained pursuant to subsection (b) of this Section 3.16
     (and, if consistent with the entries of the Agent, subsection (a)) shall be
     prima facie evidence of the existence and amounts of the obligations of the
     Borrower therein recorded; PROVIDED, HOWEVER, that the failure of any
     Lender or the Agent to maintain any such account, such Register or such
     subaccount, as applicable, or any error therein, shall not in any manner
     affect the obligation of the Borrower to repay the Loans made by such
     Lender in accordance with the terms hereof. 

          3.17 Mandatory Assignment.
     
     In the event that any Lender delivers to the Borrower, a demand for payment
in accordance with Section 3.6, 3.9 or 3.11 then, provided that no Default or
Event of Default has 

                                      62

<PAGE>

occurred and is continuing at such time, the Borrower may, at its own expense 
(such expense to include the administrative fee payable to the Agent under 
Section 11.3(b)), and with the consent of the Agent (such consent not to be 
unreasonably withheld), require such Lender to transfer and assign in whole, 
without recourse (in accordance with and subject to the terms and conditions 
of Section 11.3), all of its interests, rights and obligations under this 
Credit Agreement to an Eligible Assignee which shall assume such assigned 
obligations; PROVIDED that (i) such assignment shall not conflict with any 
law, rule or regulation or order of any court or any Governmental Authority 
and (ii) the Borrower or such assignee shall have paid to the assigning 
Lender in immediately available funds the principal of and interest accrued 
to the date of such payment on the Loans made by it hereunder and all other 
amounts owed to it hereunder.

SECTION 4
     
     GUARANTY

          4.1  THE GUARANTY.

     Each of the Guarantors hereby jointly and severally guarantees to each
Lender, each Affiliate of a Lender that enters into a Hedging Agreement, and the
Agent as hereinafter provided the prompt payment of the Credit Party Obligations
in full when due (whether at stated maturity, as a mandatory prepayment, by
acceleration, as a mandatory cash collateralization or otherwise) strictly in
accordance with the terms thereof.  The Guarantors hereby further agree that if
any of the Credit Party Obligations are not paid in full when due (whether at
stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash
collateralization or otherwise), the Guarantors will, jointly and severally,
promptly pay the same, without any demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the Credit Party
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, as a mandatory prepayment, by acceleration, as a mandatory
cash collateralization or otherwise) in accordance with the terms of such
extension or renewal.

     Notwithstanding any provision to the contrary contained herein or in any
other of the Credit Documents or Hedging Agreements, the obligations of each
Guarantor hereunder shall be limited to an aggregate amount equal to the largest
amount that would not render its obligations hereunder subject to avoidance
under Section 548 of the Bankruptcy Code or any comparable provisions of any
applicable state law.

          4.2  OBLIGATIONS UNCONDITIONAL.

     The obligations of the Guarantors under Section 4.1 are joint and several,
absolute and unconditional, irrespective of the value, genuineness, validity,
regularity or enforceability of any of the Credit Documents or Hedging
Agreements, or any other agreement or instrument referred to therein, or any
substitution, release, impairment or exchange of any other guarantee of or
security for any of the Credit Party Obligations, and, to the fullest extent
permitted by applicable law, irrespective of any other circumstance whatsoever

equitable discharge or defense of a surety or guarantor, it being the intent 
of this Section 4.2 that the obligations of the Guarantors hereunder shall be 
absolute and unconditional under any and all circumstances.  Each Guarantor 
agrees that such Guarantor shall have no right of subrogation, indemnity, 
reimbursement or contribution against the Borrower or any other Guarantor of 
the Credit Party Obligations for amounts paid under this Section 4 until such 
time as the Lenders (and any Affiliates of Lenders entering into Hedging 
Agreements) have been paid in full, all Commitments under this Credit 
Agreement have been terminated and no Person or Governmental Authority shall 
have any right to request any return or reimbursement of funds from the 
Lenders in connection with monies received under the Credit Documents or 
Hedging Agreements.  Without limiting the generality of the foregoing, it is 
agreed that, to the fullest extent permitted by law, the occurrence of any 
one or more of the following shall not alter or impair the liability of any 
Guarantor hereunder which shall remain absolute and unconditional as 
described above:

          (a)  at any time or from time to time, without notice to any
     Guarantor, the time for any performance of or compliance with any of the
     Credit Party Obligations shall be extended, or such performance or
     compliance shall be waived;

          (b)  any of the acts mentioned in any of the provisions of any
     of the Credit Documents, any Hedging Agreement or any other agreement or
     instrument referred to in the Credit Documents or Hedging Agreements shall
     be done or omitted;

          (c)  the maturity of any of the Credit Party Obligations shall
     be accelerated, or any of the Credit Party Obligations shall be modified,
     supplemented or amended in any respect, or any right under any of the
     Credit Documents, any Hedging Agreement or any other agreement or
     instrument referred to in the Credit Documents or Hedging Agreements shall
     be waived or any other guarantee of any of the Credit Party Obligations or
     any security therefor shall be released, impaired or exchanged in whole or
     in part or otherwise dealt with;

          (d)  any Lien granted to, or in favor of, the Agent or any
     Lender or Lenders as security for any of the Credit Party Obligations shall
     fail to attach or be perfected; or

          (e)  any of the Credit Party Obligations shall be determined
     to be void or voidable (including, without limitation, for the benefit of
     any creditor of any Guarantor) or shall be subordinated to the claims of
     any Person (including, without limitation, any creditor of any Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that the Agent or any Lender exhaust any right,
power or remedy or proceed against any Person under any of the Credit Documents,
any Hedging Agreement or any other agreement or instrument referred to in the
Credit Documents or Hedging Agreements, or against any other Person under any
other guarantee of, or security for, any of the Credit Party Obligations.

          4.3  REINSTATEMENT.

     The obligations of the Guarantors under this Section 4 shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Credit Party Obligations is
rescinded or must be otherwise restored by any holder of any of the Credit Party
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each Guarantor agrees that it will indemnify
the Agent and each Lender on demand for all reasonable costs and expenses
(including, without limitation, fees and expenses of counsel) incurred by the
Agent or such Lender in connection with such rescission or restoration,
including any such costs and expenses incurred in defending against any claim
alleging that such payment constituted a preference, fraudulent transfer or
similar payment under any bankruptcy, insolvency or similar law.

          4.4  CERTAIN ADDITIONAL WAIVERS.

     Without limiting the generality of the provisions of this Section 4, each
Guarantor hereby specifically waives the benefits of N.C. Gen. Stat. Sections
26-7 through 26-9, inclusive, to the extent applicable.  Each Guarantor further
agrees that such Guarantor shall have no right of recourse to security for the
Credit Party Obligations, except through the exercise of rights of subrogation
pursuant to Section 4.2 and through the exercise of rights of contribution
pursuant to Section 4.6.

          4.5  REMEDIES.

     The Guarantors agree that, to the fullest extent permitted by law, as
between the Guarantors, on the one hand, and the Agent and the Lenders, on the
other hand, the Credit Party Obligations may be declared to be forthwith due and
payable as provided in Section 9.2 (and shall be deemed to have become
automatically due and payable in the circumstances provided in said Section 9.2)
for purposes of Section 4.1 notwithstanding any stay, injunction or other
prohibition preventing such declaration (or preventing the Credit Party
Obligations from becoming automatically due and payable) as against any other
Person and that, in the event of such declaration (or the Credit Party
Obligations being deemed to have become automatically due and payable), the
Credit Party Obligations (whether or not due and payable by any other Person)
shall forthwith become due and payable by the Guarantors for purposes of Section
4.1.  The Guarantors acknowledge and agree that their obligations hereunder are
secured in accordance with the terms of the Security Agreements and the other
Collateral Documents and that the Lenders may exercise their remedies thereunder
in accordance with the terms thereof.

          4.6  RIGHTS OF CONTRIBUTION.

     The Guarantors hereby agree as among themselves that, if any Guarantor
shall make an Excess Payment (as defined below), such Guarantor shall have a
right of contribution from each other Guarantor in an amount equal to such other
Guarantor's Contribution Share (as defined below) of such Excess Payment.  The
payment obligations of any Guarantor under this Section 4.6 

                                      65

<PAGE>

shall be subordinate and subject in right of payment to the prior payment in 
full to the Agent and the Lenders of the Guaranteed Obligations, and none of 
the Guarantors shall exercise any right or remedy under this Section 4.6 
against any other Guarantor until payment and satisfaction in full of all of 
such Guaranteed Obligations. For purposes of this Section 4.6, (a) 
"GUARANTEED OBLIGATIONS" shall mean any obligations arising under the other 
provisions of this Section 4; (b) "EXCESS PAYMENT" shall mean the amount paid 
by any Guarantor in excess of its Pro Rata Share of any Guaranteed 
Obligations; (c) "PRO RATA SHARE" shall mean, for any Guarantor in respect of 
any payment of Guaranteed Obligations, the ratio (expressed as a percentage) 
as of the date of such payment of Guaranteed Obligations of (i) the amount by 
which the aggregate present fair salable value of all of its assets and 
properties exceeds the amount of all debts and liabilities of such Guarantor 
(including contingent, subordinated, unmatured, and unliquidated liabilities, 
but excluding the obligations of such Guarantor hereunder) to (ii) the amount 
by which the aggregate present fair salable value of all assets and other 
properties of the Borrower and all of the Guarantors exceeds the amount of 
all of the debts and liabilities (including contingent, subordinated, 
unmatured, and unliquidated liabilities, but excluding the obligations of the 
Borrower and the Guarantors hereunder) of the Borrower and all of the 
Guarantors; PROVIDED, HOWEVER, that, for purposes of calculating the Pro Rata 
Shares of the Guarantors in respect of any payment of Guaranteed Obligations, 
any Guarantor that became a Guarantor subsequent to the date of any such 
payment shall be deemed to have been a Guarantor on the date of such payment 
and the financial information for such Guarantor as of the date such 
Guarantor became a Guarantor shall be utilized for such Guarantor in 
connection with such payment; and (d) "CONTRIBUTION SHARE" shall mean, for 
any Guarantor in respect of any Excess Payment made by any other Guarantor, 
the ratio (expressed as a percentage) as of the date of such Excess Payment 
of (i) the amount by which the aggregate present fair salable value of all of 
its assets and properties exceeds the amount of all debts and liabilities of 
such Guarantor (including contingent, subordinated, unmatured, and 
unliquidated liabilities, but excluding the obligations of such Guarantor 
hereunder) to (ii) the amount by which the aggregate present fair salable 
value of all assets and other properties of the Borrower and all of the 
Guarantors other than the maker of such Excess Payment exceeds the amount of 
all of the debts and liabilities (including contingent, subordinated, 
unmatured, and unliquidated liabilities, but excluding the obligations of the 
Borrower and the Guarantors hereunder) of the Borrower and all of the 
Guarantors other than the maker of such Excess Payment; PROVIDED, HOWEVER, 
that, for purposes of calculating the Contribution Shares of the Guarantors 
in respect of any Excess Payment, any Guarantor that became a Guarantor 
subsequent to the date of any such Excess Payment shall be deemed to have 
been a Guarantor on the date of such Excess Payment and the financial 
information for such Guarantor as of the date such Guarantor became a 
Guarantor shall be utilized for such Guarantor in connection with such Excess 
Payment.  This Section 4.6 shall not be deemed to affect any right of 
subrogation, indemnity, reimbursement or contribution that any Guarantor may 
have under applicable law against the Borrower in respect of any payment of 
Guaranteed Obligations.  Notwithstanding the foregoing, all rights of 
contribution against any Guarantor shall terminate from and after such time, 
if ever, that such Guarantor shall be relieved of its obligations pursuant to 
Section 8.4.

          4.7  CONTINUING GUARANTEE.

     The guarantee in this Section 4 is a continuing guarantee, and shall apply
to all Credit Party Obligations whenever arising.

     Each Consolidated Party is in compliance with all Requirements of Law and

          6.12  ERISA.

     Except as disclosed and described in SCHEDULE 6.12 attached hereto:

          (a)  During the five-year period prior to the date on which
     this representation is made or deemed made: (i) no ERISA Event has
     occurred, and, to the best knowledge of the Credit Parties, no event or
     condition has occurred or exists as a result of which any ERISA Event could
     reasonably be expected to occur, with respect to any Plan; (ii) no
     "accumulated funding deficiency," as such term is defined in Section 302 of
     ERISA and Section 412 of the Code, whether or not waived, has occurred with
     respect to any Plan; (iii) each Plan has been maintained, operated, and
     funded in compliance with its own terms and in material compliance with the

     laws; and (iv) no lien in favor of the PBGC or a Plan has arisen or is
     reasonably likely to arise on account of any Plan.
     
          (b)  The actuarial present value of all "benefit liabilities"
     (as defined in Section 4001(a)(16) of ERISA), whether or not vested, under
     each Single Employer Plan, as of the last annual valuation date prior to
     the date on which this representation is made or deemed made (determined,
     in each case, in accordance with Financial Accounting Standards Board
     Statement 87, utilizing the actuarial assumptions used in such Plan's most
     recent actuarial valuation report), did not exceed as of such valuation
     date the fair market value of the assets of such Plan.
     
          (c)  Neither any Consolidated Party nor any ERISA Affiliate
     has incurred, or, to the best knowledge of the Credit Parties, could be

                                      75

<PAGE>

     Neither any Consolidated Party nor any ERISA Affiliate would become subject
     to any withdrawal liability under ERISA if any Consolidated Party or any 
     ERISA Affiliate were to withdraw completely from all Multiemployer Plans 
     and Multiple Employer Plans as of the valuation date most closely preceding
     the date on which this representation is made or deemed made.  Neither any 
     Consolidated Party nor any ERISA Affiliate has received any notification 
     that any Multiemployer Plan is in reorganization (within the meaning of 
     Section 4241 of ERISA), is insolvent (within the meaning of Section 4245 of
     ERISA), or has been terminated (within the meaning of Title IV of ERISA), 
     and no Multiemployer Plan is, to the best knowledge of the Credit Parties,
     reasonably expected to be in reorganization, insolvent, or terminated.
     
          (d)  No prohibited transaction (within the meaning of Section
     406 of ERISA or Section 4975 of the Code) or breach of fiduciary
     responsibility has occurred with respect to a Plan which has subjected or
     may subject any Consolidated Party or any ERISA Affiliate to any liability
     under Sections 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the
     Code, or under any agreement or other instrument pursuant to which any
     Consolidated Party or any ERISA Affiliate has agreed or is required to
     indemnify any person against any such liability. 
     
          (e)  Neither any Consolidated Party nor any ERISA Affiliates
     has any material liability with respect to "expected post-retirement
     benefit obligations" within the meaning of the Financial Accounting
     Standards Board Statement 106. Each Plan which is a welfare plan (as
     defined in Section 3(1) of ERISA) to which Sections 601-609 of ERISA and
     Section 4980B of the Code apply has been administered in compliance in all
     material respects of such sections.
     
          (f)  Neither the execution and delivery of this Credit Agreement 
     nor the consummation of the financing transactions contemplated
     thereunder will involve any transaction which is subject to the
     prohibitions of Sections 404, 406 or 407 of ERISA or in connection with
     which a tax could be imposed pursuant to Section 4975 of the Code.  The
     representation by the Credit Parties in the preceding sentence is made in
     reliance upon and subject to the accuracy of the Lenders' representation in
     Section 11.14 with respect to their source of funds and is subject, in the
     event that the source of the funds used by the Lenders in connection with
     this transaction is an insurance company's general asset account, to the
     application of Prohibited Transaction Class Exemption 95-60, 60 Fed. Reg.
     35,925 (1995), compliance with the regulations issued under Section
     401(c)(1)(A) of ERISA, or the issuance of any other prohibited transaction
     exemption or similar relief, to the effect that assets in an insurance
     company's general asset account do not constitute assets of an "employee
     benefit plan" within the meaning of Section 3(3) of ERISA of a "plan"
     within the meaning of Section 4975(e)(1) of the Code.

owned (directly or indirectly) by such Consolidated Party; and the number and

The outstanding Capital Stock of all such Subsidiaries is validly issued, 
fully paid and non-assessable and is owned by each such Consolidated Party, 
directly or indirectly, free and clear of all Liens (other than those arising 
under or contemplated in connection with the Credit Documents).  Other than

issuance (contingent or otherwise) of, or any calls, commitments or claims of 
any character relating to its Capital Stock.  SCHEDULE 6.13 may be updated

     carrying any "margin stock" within the meaning of Regulation G or
     Regulation U, or for the purpose of purchasing or carrying or trading in
     any securities.  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 U-1 referred to in Regulation
     U.  No indebtedness being reduced or retired out of the proceeds of the
     Loans was or will be incurred for the purpose of purchasing or carrying any
     margin stock within the meaning of Regulation U or any "margin security"
     within the meaning of Regulation T.  "Margin stock" within the meaning of
     Regulation U does not constitute more than 25% of the value of the
     consolidated assets of the Consolidated Parties.  None of the transactions
     contemplated by this Credit Agreement (including, without limitation, the
     direct or indirect use of the proceeds of the Loans) will violate or result
     in a violation of the Securities Act of 1933, as amended, or the Securities
     Exchange Act of 1934, as amended, or regulations issued pursuant thereto,
     or Regulation G, T, U or X.

          (c)   No director, executive officer or principal shareholder
     of any Consolidated Party is a director, executive officer or principal
     shareholder of any Lender.  For the purposes hereof the terms "director",
     "executive officer" and "principal shareholder" (when used with reference
     to any Lender) have the respective meanings assigned thereto in Regulation
     O issued by the Board of Governors of the Federal Reserve System.

     authorizations, qualifications, accreditations, easements, rights of way
     and other rights, consents and approvals which are necessary for the
     ownership of its respective Property and to the conduct of its respective
     businesses as presently conducted unless the failure to do so would not
     have a Material Adverse Effect.

     statute, regulation or ordinance of the United States of America, or of any
     state, city, town, municipality, county or any other jurisdiction, or of
     any agency thereof (including without limitation, environmental laws and
     regulations), which violation could reasonably be expected to have a
     Material Adverse Effect.

          (f)   Each Consolidated Party is current with all material
     reports and documents, if any, required to be filed with any state or
     federal securities commission or similar agency and is in full compliance
     in all material respects with all applicable rules and regulations of such

     Effect.

          7.5   PAYMENT OF TAXES AND OTHER INDEBTEDNESS.

     Each Credit Party will, and will cause each of its Subsidiaries to, pay and
discharge (a) all taxes, assessments and governmental charges or levies imposed
upon it, or upon its income or profits, or upon any of its properties, before

materials and supplies) which, if unpaid, might give rise to a Lien upon any of
its properties, and (c) except as prohibited hereunder, all of its other
Indebtedness as it shall become due; PROVIDED, HOWEVER, that no Consolidated
Party shall be required to pay any such tax, assessment, charge, levy, claim or
Indebtedness which is being contested in good faith by appropriate proceedings
and as to which adequate reserves therefor have been established in accordance
with GAAP, unless the failure to make any such payment (i) could give rise to an
immediate right to foreclose on a Lien securing such amounts or (ii) could
reasonably be expected to have a Material Adverse Effect.

          7.6   INSURANCE.

          (a)   Each Credit Party will, and will cause each of its
     Subsidiaries to, at all times maintain in full force and effect insurance
     (including worker's compensation insurance, liability insurance, casualty
     insurance and business interruption insurance) in such amounts, covering
     such risks and liabilities and with such deductibles or self-insurance
     retentions as are in accordance with normal industry practice (or as
     otherwise required by the Collateral Documents). The Agent shall be named
     as loss payee or mortgagee, as its interest may appear, and/or additional
     insured with respect to any such insurance providing coverage in respect of
     any Collateral, and each provider of any such insurance shall agree, by
     endorsement upon the policy or policies issued by it or by independent
     instruments furnished to the Agent, that it will use good faith efforts to
     give the Agent thirty (30) days prior written notice before any such policy
     or policies shall be altered or canceled, and that no act or default of any
     Consolidated Party or any other Person shall affect the rights of the Agent
     or the Lenders under such policy or policies.  The present insurance
     coverage of the Consolidated Parties is outlined as to carrier, policy
     number, expiration date, type and amount on SCHEDULE 7.6.

     describing the nature and extent of such damage or destruction.  In case of
     any loss, damage to or destruction of the Collateral of any Credit Party or
     any part thereof, such Credit Party, whether or not the insurance proceeds,
     if any, received on account of such damage or destruction shall be
     sufficient for that purpose, at such Credit Party's cost and expense, will
     promptly repair or replace the Collateral of such Credit Party so lost,
     damaged or destroyed; PROVIDED, HOWEVER, that such Credit Party need not
     repair or replace the Collateral of such Credit Party so lost, damaged or
     destroyed to the extent the failure to make such repair or replacement (i)
     is desirable to the proper conduct of the business of such Credit Party in
     the ordinary course and otherwise in the best interest of such Credit
     Party; and (ii) would not materially impair the rights and benefits of the
     Agent or the Lenders under the Collateral Documents, any other Credit
     Document or any Hedging 


                                      84

     Agreement.  In the event a Credit Party shall receive any proceeds of such 
     insurance in a net amount in excess of $500,000, such Credit Party will 
     immediately pay over such proceeds to the Agent, for payment on the Credit 
     Party Obligations; PROVIDED, HOWEVER, that the Agent agrees to release such
     insurance proceeds to such Credit Party for replacement or restoration of 
     the portion of the Collateral of such Credit Party lost, damaged or 
     destroyed if, but only if, (A) no Default or Event of Default shall have 
     occurred and be continuing at the time of release, (B) written application 
     for such release is received by the Agent from such Credit Party within 
     30 days of receipt of such proceeds and (C) the Agent has received evidence
     reasonably satisfactory to it that the Collateral lost, damaged or 
     destroyed has been or will be replaced or restored to its condition 
     immediately prior to the loss, destruction or other event giving rise to 
     the payment of such insurance proceeds.

          7.7   MAINTENANCE OF PROPERTY.

     Each Credit Party will, and will cause each of its Subsidiaries to,
maintain and preserve its properties and equipment material to the conduct of
its business in good repair, working order and condition, normal wear and tear
and casualty and condemnation excepted, and will make, or cause to be made, in
such properties and equipment from time to time all repairs, renewals,
replacements, extensions, additions, betterments and improvements thereto as may
be needed or proper, to the extent and in the manner customary for companies in
similar businesses.

          7.8   PERFORMANCE OF OBLIGATIONS.

     Each Credit Party will, and will cause each of its Subsidiaries to, perform
in all material respects all of its obligations  under the terms of all material
agreements, indentures, mortgages, security agreements or other debt instruments
to which it is a party or by which it is bound.

          7.9   USE OF PROCEEDS.

     The Borrower will use the proceeds of the Loans and will use the Letters of
Credit solely for the purposes set forth in Section 6.15.

          7.10  AUDITS/INSPECTIONS.

     Upon reasonable notice and during normal business hours, each Credit Party
will, and will cause each of its Subsidiaries to, permit representatives
appointed by the Agent, including, without limitation, independent accountants,
agents, attorneys, and appraisers to visit and inspect its property, including
its books and records, its accounts receivable and inventory, its facilities and
its other business assets, and to make photocopies or photographs thereof and to
write down and record any information such representative obtains and shall
permit the Agent or its representatives to investigate and verify the accuracy
of information provided to the Lenders and to discuss all such matters with the
officers, employees and representatives of such Person.  The Credit Parties
agree 


                                      85

that the Agent, and its representatives, may conduct an annual audit of the

          7.12  ADDITIONAL CREDIT PARTIES.

     As soon as practicable and in any event within 30 days after any Person

intellectual property, securities, instruments, chattel paper or other personal
property required to be delivered to the Agent as Collateral hereunder or under
any of the Collateral Documents or (b) acquire or lease any real property, the
Borrower shall promptly (and in any event within three (3) Business Days) after

to, take such action (including but not limited to the actions set forth in
Sections 5.2(a) and Section 7.16 (as qualified by this Section 7.13)) at its own
expense as requested by the Agent to ensure that the Agent has a first priority
(subject to Permitted Liens), perfected Lien to secure the Credit Party
Obligations in (i) all owned real property and personal property of the Credit
Parties located in the United States, (ii) to the extent deemed to be material
by the Agent or the Required Lenders in its or their sole reasonable discretion,

rates as to which the material terms are reasonably satisfactory to the Agent
and the Borrower, which agreements shall provide coverage in an amount equal to
at least $25 million and for a duration of at least 3 years.

          7.15  UPSTREAMING OF INCOME FROM JOINT VENTURES.

The Credit Parties will cause each of the Joint Ventures to distribute to the
Borrower from time to time (and in any event at least once during each fiscal
year of the Borrower) the Borrower's share of the net income before taxes for
such period (as determined in accordance with GAAP) of such Joint Venture.

          7.16  FURTHER ASSURANCES.

          (a)   Within 90 days after the Closing Date, the Credit Parties
     shall deliver to the Agent:

          INSTRUMENT" and collectively the "MORTGAGE INSTRUMENTS") encumbering
          the fee interest and/or leasehold interest of any Credit Party in each

          REAL PROPERTY" and collectively the "PRIMARY REAL PROPERTIES");

                (ii)  in the case of each leasehold interest of any
          Credit Party in each real property asset designated in SCHEDULE

          "SECONDARY REAL PROPERTIES") or Primary Real Property (each Primary
          Real Property or Secondary Real Property a "REAL PROPERTY" and
          collectively the "REAL PROPERTIES"), (a) such estoppel letters,
          consents and waivers from the landlords on such real property as may
          be required by the Agent, which estoppel letters shall be in the form

          that the applicable lease, a memorandum of lease with respect thereto,
          or other evidence of such lease in form and substance reasonably
          satisfactory to the Agent, has been or will be recorded in all places
          to the extent necessary or desirable, in the reasonable judgment of
          the Agent, so as to enable the Mortgage Instrument encumbering such
          leasehold interest to effectively create a valid and enforceable first
          priority lien (subject to Permitted Liens) on such leasehold interest
          in favor of the Agent (or such other Person as may be required or
          desired under local law) for the benefit of Lenders;

                (iii) ALTA mortgagee title insurance policies issued by
          Chicago Title Insurance Company (the "MORTGAGE POLICIES"), in amounts
          reasonably satisfactory to the Agent, assuring the Agent that each of
          the Mortgage Instruments creates a valid and enforceable first
          priority mortgage lien on the applicable Primary Real Property, free
          and clear of all defects and encumbrances except Permitted Liens,
          which Mortgage Policies shall be in form and substance reasonably
          satisfactory to the Agent and shall provide for affirmative insurance
          and such reinsurance as the Agent may reasonably request, all of the
          foregoing in form and substance reasonably satisfactory to the Agent;
          and 


                                      89

     other than by a regularly scheduled required prepayment, prior to the
     stated maturity thereof; or

          (g)    JUDGMENTS.  One or more judgments or decrees shall be
     entered against one or more of the Consolidated Parties involving a
     liability of $1,000,000 or more in the aggregate (to the extent not paid or

     coverage and has the ability to perform) and any such judgments or

                                       98

     Adverse Effect: (i) any "accumulated funding deficiency," as such term is
     defined in Section 302 of ERISA and Section 412 of the Code, whether or not
     waived, shall exist with respect to any Plan, or any lien shall arise on
     the assets of any Consolidated Party or any ERISA Affiliate in favor of the
     PBGC or a Plan; (ii) an ERISA Event shall occur with respect to a Single
     Employer Plan, which is, in the reasonable opinion of the Agent, likely to
     result in the termination of such Plan for purposes of Title IV of ERISA;
     (iii) an ERISA Event shall occur with respect to a Multiemployer Plan or
     Multiple Employer Plan, which is, in the reasonable opinion of the Agent,
     likely to result in (A) the termination of such Plan for purposes of Title
     IV of ERISA, or (B) any Consolidated Party or any ERISA Affiliate incurring
     any liability in connection with a withdrawal from, reorganization of
     (within the meaning of Section 4241 of ERISA), or insolvency or (within the
     meaning of Section 4245 of ERISA) such Plan; or (iv) any prohibited
     transaction (within the meaning of Section 406 of ERISA or Section 4975 of
     the Code) or breach of fiduciary responsibility shall occur which may
     subject any Consolidated Party or any ERISA Affiliate to any liability
     under Sections 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the
     Code, or under any agreement or other instrument pursuant to which any

     indemnify any person against any such liability; or
     
          (j)    INDEMNIFICATION CLAIM UNDER INVESTMENT AGREEMENTS.  The
     Borrower shall be required to make any indemnification payment of
     $1,000,000 or more under Article VIII of either of the Investment
     Agreements (to the extent not paid or fully covered by insurance provided
     by a carrier who has acknowledged coverage and has the ability to perform)
     and any such indemnification payment shall remain unpaid for at least 60
     days from the date of demand thereof; or
     
          (k)    OWNERSHIP.  There shall occur a Change of Control.

          9.2    ACCELERATION; REMEDIES.

     Upon the occurrence of an Event of Default, and at any time thereafter
unless and until such Event of Default has been waived by the requisite Lenders
(pursuant to the voting requirements of Section 11.6) or cured to the
satisfaction of the requisite Lenders (pursuant to the voting procedures in
Section 11.6), the Agent shall, upon the request and direction of the Required
Lenders, by written notice to the Credit Parties take any of the following
actions:

          (a)    TERMINATION OF COMMITMENTS.  Declare the Commitments
     terminated whereupon the Commitments shall be immediately terminated.

          (b)    ACCELERATION.  Declare the unpaid principal of and any
     accrued interest in respect of all Loans, any reimbursement obligations
     arising from drawings under Letters of Credit and any and all other
     indebtedness or obligations of any and every kind owing by the

                                       99

<PAGE>

     Borrower to the Agent and/or any of the Lenders hereunder to be due
     whereupon the same shall be immediately due and payable without
     presentment, demand, protest or other notice of any kind, all of
     which are hereby waived by the Borrower.

          (c)    CASH COLLATERAL.  Direct the Borrower to pay (and the
     Borrower agrees that upon receipt of such notice, or upon the occurrence of
     an Event of Default under Section 9.1(f), it will immediately pay) to the
     Agent additional cash, to be held by the Agent, for the benefit of the
     Lenders, in a cash collateral account as additional security for the LOC
     Obligations in respect of subsequent drawings under all then outstanding
     Letters of Credit in an amount equal to the maximum aggregate amount which
     may be drawn under all Letters of Credits then outstanding.

          (d)    ENFORCEMENT OF RIGHTS.  Enforce any and all rights and
     interests created and existing under the Credit Documents including,
     without limitation, all rights and remedies existing under the Collateral
     Documents, all rights and remedies against a Guarantor and all rights of
     set-off.

     Notwithstanding the foregoing, if an Event of Default specified in Section
9.1(f) shall occur, then the Commitments shall automatically terminate and all
Loans, all reimbursement obligations arising from drawings under Letters of
Credit, all accrued interest in respect thereof, all accrued and unpaid Fees and
other indebtedness or obligations owing to the Agent and/or any of the Lenders
hereunder automatically shall immediately become due and payable without the
giving of any notice or other action by the Agent or the Lenders.


SECTION 10
     
     AGENCY PROVISIONS

          10.1   APPOINTMENT, POWERS AND IMMUNITIES.

     Each Lender hereby irrevocably appoints and authorizes the Agent to act as
its agent under this Credit Agreement and the other Credit Documents with such
powers and discretion as are specifically delegated to the Agent by the terms of
this Credit Agreement and the other Credit Documents, together with such other
powers as are reasonably incidental thereto.  The Agent (which term as used in
this sentence and in Section 10.5 and the first sentence of Section 10.6 hereof
shall include its Affiliates and its own and its Affiliates' officers,
directors, employees, and agents):  (a) shall not have any duties or
responsibilities except those expressly set forth in this Credit Agreement and
shall not be a trustee or fiduciary for any Lender; (b) shall not be responsible
to the Lenders for any recital, statement, representation, or warranty (whether
written or oral) made in or in connection with any Credit Document or any
certificate or other document referred to or provided for in, or received by any
of them under, any Credit Document, or for the value, validity, effectiveness,
genuineness, enforceability, or sufficiency of any Credit Document, or any other
document referred to or provided for therein or for any failure by any Credit
Party or any other Person to perform any of its obligations thereunder; (c)
shall not be

                                       100

<PAGE>

responsible for or have any duty to  ascertain, inquire into, or
verify the performance or observance of any covenants or agreements by any
Credit Party or the satisfaction of any condition or to inspect the property
(including the books and records) of any Credit Party or any of its Subsidiaries
or Affiliates; (d) shall not be required to initiate or conduct any litigation
or collection proceedings under any Credit Document; and (e) shall not be
responsible for any action taken or omitted to be taken by it under or in
connection with any Credit Document, except for its own gross negligence or
willful misconduct.  The Agent may employ agents and attorneys-in-fact and shall
not be responsible for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care.

          10.2   RELIANCE BY AGENT.

     The Agent shall be entitled to rely upon any certification, notice,
instrument, writing, or other communication (including, without limitation, any
thereof by telephone or telecopy) believed by it to be genuine and correct and
to have been signed, sent or made by or on behalf of the proper Person or
Persons, and upon advice and statements of legal counsel (including counsel for
any Credit Party), independent accountants, and other experts selected by the
Agent.  The Agent may deem and treat the payee of any Note as the holder thereof
for all purposes hereof unless and until the Agent receives and accepts an
Assignment and Acceptance executed in accordance with Section 11.3(b) hereof. 
As to any matters not expressly provided for by this Credit Agreement, the Agent
shall not be required to exercise any discretion or take any action, but shall
be required to act or to refrain from acting (and shall be fully protected in so
acting or refraining from acting) upon the  instructions of the Required
Lenders, and such instructions shall be binding on all of the Lenders; PROVIDED,
HOWEVER, that the Agent shall not be required to take any action that exposes
the Agent to personal liability or that is contrary to any Credit Document or
applicable law or unless 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 any such action.

          10.3   DEFAULTS.

     The Agent shall not be deemed to have knowledge or notice of the occurrence
of a Default or Event of Default unless the Agent has received written notice
from a Lender or the Borrower specifying 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 of the occurrence of a Default or Event of Default, the
Agent shall give prompt notice thereof to the Lenders.  The Agent shall (subject
to Section 10.2 hereof) take such action with respect to such Default or Event
of Default as shall reasonably be directed by the Required Lenders, PROVIDED
THAT, unless and until the Agent shall have received such directions, the Agent
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 interest of the Lenders.

                                       101

<PAGE>


          10.4   RIGHTS AS A LENDER.

     With respect to its Commitment and the Loans made by it, NationsBank (and
any successor acting as Agent) in its capacity as a Lender hereunder shall have
the same rights and powers hereunder as any other Lender and may exercise the
same as though it were not acting as the Agent, and the term "Lender" or
"Lenders" shall, unless the context otherwise indicates, include the Agent in
its individual capacity. NationsBank (and any successor acting as Agent) and its
Affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to, make investments in, provide services to, and
generally engage in any kind of lending, trust, or other business with any
Credit Party or any of its Subsidiaries or Affiliates as if it were not acting
as Agent, and NationsBank (and any successor acting as Agent) and its Affiliates
may accept fees and other consideration from any Credit Party or any of its
Subsidiaries or Affiliates for services in connection with this Credit Agreement
or otherwise without having to account for the same to the Lenders.

          10.5   INDEMNIFICATION.

     The Lenders agree to indemnify the Agent (to the extent not reimbursed
under Section 11.5 hereof, but without limiting the obligations of the Borrower
under such Section) ratably in accordance with their respective Commitments, for
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses (including attorneys' fees), or disbursements
of any kind and nature whatsoever that may be imposed on, incurred by or
asserted against the Agent (including by any Lender) in any way relating to or
arising out of any Credit Document or the transactions contemplated thereby or
any action taken or omitted by the Agent under any Credit Document (including
any of the foregoing arising from the negligence of the Agent; PROVIDED that no
Lender shall be liable for any of the foregoing to the extent they arise from
the gross negligence or willful misconduct of the Person to be indemnified. 
Without limitation of the foregoing, each Lender agrees to reimburse the Agent
promptly upon demand for its ratable share of any costs or expenses payable by
the Borrower under Section 11.5, to the extent that the Agent is not promptly
reimbursed for such costs and expenses by the Borrower. The agreements in this
Section 10.5 shall survive the repayment of the Loans, LOC Obligations and other
obligations under the Credit Documents and the termination of the Commitments
hereunder.

          10.6   NON-RELIANCE ON AGENT AND OTHER LENDERS.

     Each Lender agrees that it has, independently and without reliance on the
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own credit analysis of the Credit Parties and their
Subsidiaries and decision to enter into this Credit Agreement and 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 analysis and decisions in taking or not taking action
under the Credit Documents.  Except for notices, reports, and other documents
and information 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

                                       102

<PAGE>

affairs, financial condition, or business of any Credit Party or any of its
Subsidiaries or Affiliates that may come into the possession of the Agent or
any of its Affiliates.

          10.7   SUCCESSOR AGENT.

     The Agent may resign at any time by giving notice thereof to the Lenders
and the Borrower.  Upon any such resignation, the Borrower, with the consent of
the Required Lenders (such consent not to be unreasonably withheld) shall have
the right to appoint a successor Agent from among the Lenders.  If no successor
Agent shall have been so appointed by the Required Lenders and shall have
accepted such appointment within thirty (30) days after the retiring Agent's
giving of notice of resignation, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent which shall be a commercial bank organized
under the laws of the United States of America having combined capital and
surplus of at least $100,000,000.  Upon the acceptance of any appointment as
Agent hereunder by a successor, such successor shall thereupon succeed to and
become vested with all the rights, powers, discretion, privileges, and duties of
the retiring Agent, and the retiring Agent shall be discharged from its duties
and obligations hereunder.  After any retiring Agent's  resignation hereunder as
Agent, the provisions of this Section 10 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Agent.

          11.2   RIGHT OF SET-OFF; ADJUSTMENTS.

     Upon the occurrence and during the continuance of any Event of Default, 
each Lender (and each of its Affiliates) is hereby authorized at any time and 
from time to time, to the fullest extent permitted by law, to set off and 
apply any and all deposits (general or special, time or demand, provisional 
or final) at any time held and other indebtedness at any time owing by such 
Lender (or any of its Affiliates) to or for the credit or the account of any 
Credit Party against any

                                       104

<PAGE>

and all of the obligations of such Person now or hereafter existing under 
this Credit Agreement, under the Notes, under any other Credit Document or 
otherwise, irrespective of whether such Lender shall have made any demand 
under hereunder or thereunder and although such obligations may be unmatured. 
Each Lender agrees promptly to notify any affected Credit Party after any 
such set-off and application made by such Lender; PROVIDED, HOWEVER, that the 
failure to give such notice shall not affect the validity of such set-off and 
application. The rights of each Lender under this Section 11.2  are in 
addition to other rights and remedies (including, without limitation, other 
rights of set-off) that such Lender may have.

          11.3   BENEFIT OF AGREEMENT.
     
          (a)    This Credit Agreement shall be binding upon and inure to
     the benefit of and be enforceable by the respective successors and assigns
     of the parties hereto; PROVIDED that none of the Credit Parties may assign
     or transfer any of its interests and obligations without prior written
     consent of the Lenders; PROVIDED FURTHER that the rights of each Lender to
     transfer, assign or grant participations in its rights and/or obligations
     hereunder shall be limited as set forth in this Section 11.3.
     
          (b)    Each Lender may assign to one or more Eligible Assignees
     all or a portion of its rights and obligations under this Credit Agreement
     (including, without limitation, all or a portion of its Loans, its Notes,
     and its Commitment); PROVIDED, HOWEVER, that 
     
                 (i)     each such assignment shall be to an Eligible
          Assignee;
          
                 (ii)    except in the case of an assignment to another
          Lender or an assignment of all of a Lender's rights and obligations
          under this Credit Agreement, any such partial assignment shall be in
          an amount at least equal to $5,000,000 (or, if less, the remaining
          amount of the Commitment being assigned by such Lender) or an integral
          multiple of $1,000,000 in excess thereof;
          
                 (iii)   each such assignment by a Lender shall be of a
          constant, and not varying, percentage of all of its rights and
          obligations under this Credit Agreement and the Notes; and
          
                 (iv)    the parties to such assignment shall execute and
          deliver to the Agent for its acceptance an Assignment and Acceptance
          in the form of Exhibit 11.3(b) hereto, together with any Note subject
          to such assignment and a processing fee of $3,500.
     
     Upon execution, delivery, and acceptance of such Assignment and Acceptance,
     the assignee thereunder shall be a party hereto and, to the extent of such
     assignment, have the obligations, rights, and benefits of a Lender
     hereunder and the assigning Lender shall, to the extent of such assignment,
     relinquish its rights and be released from its obligations under this
     Credit Agreement.  Upon the consummation of any assignment pursuant to this
     Section 11.3(b), the assignor, the Agent and the Borrower shall make
     appropriate arrangements so that, if required, new Notes are issued to the
     assignor and the assignee.

                                       105
<PAGE>


     If the assignee is not incorporated under the laws of the United 
     States of America or a state thereof, it shall deliver to the 
     Borrower and the Agent certification as to exemption from deduction      
     or withholding of Taxes in accordance with Section 3.11.
     
          (c)    The Agent shall maintain at its address referred to in
     Section 11.1 a copy of each Assignment and Acceptance delivered to and
     accepted by it and a register for the recordation of the names and
     addresses of the Lenders and the Commitment of, and principal amount of the
     Loans owing to, each Lender from time to time (the "REGISTER").  The
     entries in the Register shall be conclusive and binding for all purposes,
     absent manifest error, and the Borrower, the Agent and the Lenders may
     treat each Person whose name is recorded in the Register as a Lender
     hereunder for all purposes of this Credit Agreement.  The Register shall be
     available for inspection by the Borrower or any Lender at any reasonable
     time and from time to time upon reasonable prior notice.
     
          (d)    Upon its receipt of an Assignment and Acceptance executed
     by the parties thereto, together with any Note subject to such assignment
     and payment of the processing fee, the Agent shall, if such Assignment and
     Acceptance has been completed and is in substantially the form of Exhibit
     11.3(b) hereto, (i) accept such Assignment and Acceptance, (ii) record the
     information contained therein in the Register and (iii) give prompt notice
     thereof to the parties thereto.
     
          (e)    Each Lender may sell participations to one or more
     Persons in all or a portion of its rights and obligations under this Credit
     Agreement (including all or a portion of its Commitment and its Loans);
     PROVIDED, HOWEVER, that  (i) such Lender's obligations under this Credit
     Agreement shall remain unchanged,  (ii) such Lender shall remain solely
     responsible to the other parties hereto for the performance of such
     obligations,  (iii) the participant shall be entitled to the benefit of the
     yield protection provisions contained in Sections 3.7 through 3.12,
     inclusive, and the right of set-off contained in Section 11.2, and (iv) the
     Borrower shall continue to deal solely and directly with such Lender in
     connection with such Lender's rights and obligations under this Credit
     Agreement, and such Lender shall retain the sole right to enforce the
     obligations of the Borrower relating to its Loans and its Notes and to
     approve any amendment, modification, or waiver of any provision of this
     Credit Agreement (other than amendments, modifications, or waivers
     decreasing the amount of principal of or the rate at which interest is
     payable on such Loans or Notes, extending any scheduled principal payment
     date or date fixed for the payment of interest on such Loans or Notes, or
     extending its Commitment).
     
          (f)    Notwithstanding any other provision set forth in this
     Credit Agreement, any Lender may at any time assign and pledge all or any
     portion of its Loans and its Notes to any Federal Reserve Bank as
     collateral security pursuant to Regulation A and any Operating Circular
     issued by such Federal Reserve Bank.  No such assignment shall release the
     assigning Lender from its obligations hereunder.

                                       106

<PAGE>

     
          (g)    Any Lender may furnish any information concerning the
     Borrower or any of its Subsidiaries in the possession of such Lender from
     time to time to assignees and participants (including prospective assignees
     and participants).

          11.4   NO WAIVER; REMEDIES CUMULATIVE.

     No failure or delay on the part of the Agent or any Lender in exercising
any right, power or privilege hereunder or under any other Credit Document and
no course of dealing between the Agent or any Lender and any of the Credit
Parties shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or under any other Credit
Document preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder or thereunder.  The rights and
remedies provided herein are cumulative and not exclusive of any rights or
remedies which the Agent or any Lender would otherwise have.  No notice to or
demand on any Credit Party in any case shall entitle the Borrower or any other
Credit Party to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Agent or the Lenders
to any other or further action in any circumstances without notice or demand.

          11.5   EXPENSES; INDEMNIFICATION.

     (a)  The Borrower agrees to pay on demand all costs and expenses of the
Agent in connection with the syndication, preparation, execution, delivery,
administration, modification, and amendment of this Credit Agreement, the other
Credit Documents, and the other documents to be delivered hereunder, including,
without limitation, the reasonable fees and expenses of counsel for the Agent
(including the cost of internal counsel) with respect thereto and with respect
to advising the Agent as to its rights and responsibilities under the Credit
Documents.  The Borrower further agrees to pay on demand all costs and expenses
of the Agent and the Lenders, if any (including, without limitation, reasonable
attorneys' fees and expenses and the cost of internal counsel), in connection
with the enforcement (whether through negotiations, legal proceedings, or
otherwise) of the Credit Documents and the other documents to be delivered
hereunder.

     (b)  The Borrower agrees to indemnify and hold harmless the Agent and each
Lender and each of their Affiliates and their respective officers, directors,
employees, agents, and advisors (each, an "INDEMNIFIED PARTY") from and against
any and all claims, damages, losses, liabilities, costs, and expenses
(including, without limitation, reasonable attorneys' fees) that may be incurred
by or asserted or awarded against any Indemnified Party, in each case arising
out of or in connection with or by reason of (including, without limitation, in
connection with any investigation, litigation, or proceeding or preparation of
defense in connection therewith) the Credit Documents, any of the transactions
contemplated herein or the actual or proposed use of the proceeds of the Loans
(including any of the foregoing arising from the negligence of the Indemnified
Party), except to the extent such claim, damage, loss, liability, cost, or
expense is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted from such Indemnified Party's gross negligence or
willful misconduct.  In the case of an investigation, litigation or other
proceeding to which the indemnity in this Section 11.5 applies,

                                       107

<PAGE>


such indemnity shall be effective whether or not such investigation, litigation
or proceedings brought by the Borrower, its directors, shareholders or
creditors or an Indemnified Party or any other Person or any Indemnified
Party is otherwise a party thereto and whether or not the transactions
contemplated hereby are consummated.  The Borrower agrees not to assert any
claim against the Agent, any Lender, any of their Affiliates, or any of their
respective directors, officers, employees, attorneys, agents, and advisers,
on any theory of liability, for special, indirect, consequential, or punitive
damages arising out of or otherwise relating to the Credit Documents, any of
the transactions contemplated herein or the actual or proposed use of the
proceeds of the Loans.

     (c)  Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
this Section 11.5 shall survive the repayment of the Loans, LOC Obligations and
other obligations under the Credit Documents and the termination of the
Commitments hereunder.

          11.6   AMENDMENTS, WAIVERS AND CONSENTS.

     Neither this Credit Agreement nor any other Credit Document nor any of the
terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing entered into by, or approved in writing by, the Required Lenders and the
Borrower, PROVIDED, HOWEVER, that:

          (a)    without the consent of each Lender affected thereby,
     neither this Credit Agreement nor any other Credit Document may be amended
     to


                 (i)     extend the final maturity of any Loan or the time
          of payment of any reimbursement obligation, or any portion thereof,
          arising from drawings under Letters of Credit, or extend or waive any
          Principal Amortization Payment of any Loan, or any portion thereof,

                 (ii)    reduce the rate or extend the time of payment of
          interest (other than as a result of waiving the applicability of any
          post-default increase in interest rates) thereon or Fees hereunder, 

                 (iii)   reduce or waive the principal amount of any Loan
          or of any reimbursement obligation, or any portion thereof, arising
          from drawings under Letters of Credit,

                 (v)     increase the Commitment of a Lender over the
          amount thereof in effect (it being understood and agreed that a waiver
          of any Default or Event of Default or mandatory reduction in the
          Commitments shall not constitute a change in the terms of any
          Commitment of any Lender), 

                 (v)     except as the result of or in connection with an
          Asset Disposition permitted by Section 8.5, release all or
          substantially all of the Collateral,

                                       108

<PAGE>


                 (vi)    except as the result of or in connection with a
          dissolution, merger or disposition of a Subsidiary permitted under
          Section 8.4, release the Borrower or substantially all of the other
          Credit Parties from its or their obligations under the Credit
          Documents, 

                 (vii)   except amend, modify or waive any provision of
          this Section 11.6 or Section 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12,
          3.13, 3.14, 3.15, 9.1(a), 11.2, 11.3, 11.5 or 11.9,

                 (viii)  reduce any percentage specified in, or otherwise
          modify, the definition of Required Lenders, or

                 (ix)    consent to the assignment or transfer by the
          Borrower or all or substantially all of the other Credit Parties of
          any of its or their rights and obligations under (or in respect of)
          the Credit Documents except as permitted thereby;

          (b)    without the consent of the Agent, no provision of Section
     10 may be amended;

          (c)    without the consent of the Issuing Lender, no provision
     of Section 2.2 may be amended.

     Notwithstanding the fact that the consent of all the Lenders is required in
     certain circumstances as set forth above, (x) each Lender is entitled to
     vote as such Lender sees fit on any bankruptcy reorganization plan that
     affects the Loans, and each Lender acknowledges that the provisions of
     Section 1126(c) of the Bankruptcy Code supersedes the unanimous consent
     provisions set forth herein and (y) the Required Lenders may consent to
     allow a Credit Party to use cash collateral in the context of a bankruptcy
     or insolvency proceeding.

          11.7   COUNTERPARTS.

     This Credit Agreement may be executed in any number of counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall constitute one and the same instrument.  It shall not be necessary in
making proof of this Credit Agreement to produce or account for more than one
such counterpart for each of the parties hereto.  Delivery by facsimile by any
of the parties hereto of an executed counterpart of this Credit Agreement shall
be as effective as an original executed counterpart hereof and shall be deemed a
representation that an original executed counterpart hereof will be delivered.

     All indemnities set forth herein, including, without limitation, in Section
2.2(i), 3.11, 3.12, 10.5 or 11.5 shall survive the execution and delivery of
this Credit Agreement, the making of the Loans, the issuance of the Letters of
Credit, the repayment of the Loans, LOC Obligations and other obligations under
the Credit Documents and the termination of the Commitments hereunder, and all
representations and warranties made by the Credit Parties herein shall survive

          11.10    GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE.

          (a)      THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND
     THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE
     GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF
     THE STATE OF NEW YORK.  Any legal action or proceeding with respect to this
     Credit Agreement or any other Credit Document may be brought in the courts
     of the State of North Carolina in Mecklenburg County, or of the United
     States for the Western District of North Carolina, and, by execution and
     delivery of this Credit Agreement, each of the Credit Parties hereby
     irrevocably accepts for itself and in respect of its property, generally
     and unconditionally, the nonexclusive jurisdiction of such courts.  Each of
     the Credit Parties further irrevocably consents to the service of process
     out of any of the aforementioned courts in any such action or proceeding by
     the mailing of copies thereof by registered or certified mail, postage
     prepaid, to it at the address set out for notices pursuant to Section 11.1,
     such service to become effective three (3) days after such mailing. 
     Nothing herein shall affect the right of the Agent or any Lender to serve
     process in any other manner permitted by law or to commence legal
     proceedings or to otherwise proceed against any Credit Party in any other
     jurisdiction.

          (b)     Each of the Credit Parties hereby irrevocably waives any
     objection which it may now or hereafter have to the laying of venue of any
     of the aforesaid actions or proceedings arising out of or in connection
     with this Credit Agreement or any other Credit Document brought in the
     courts referred to in subsection (a) above and hereby further irrevocably
     waives and agrees not to plead or claim in any such court that any such
     action or proceeding brought in any such court has been brought in an
     inconvenient forum.

          (c)     TO THE EXTENT PERMITTED BY LAW, EACH OF THE AGENT, THE
     LENDERS, THE BORROWER AND THE CREDIT PARTIES HEREBY IRREVOCABLY WAIVES ALL
     RIGHT TO TRIAL BY JURY IN ANY ACTION,

<PAGE>

     PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS CREDIT
     AGREEMENT, ANY OF THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS 
     CONTEMPLATED HEREBY.

          11.11    SEVERABILITY.

     If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable and
the remaining provisions shall remain in full force and effect and shall be
construed without giving effect  to the illegal, invalid or unenforceable
provisions.

          11.12    ENTIRETY.

     This Credit Agreement together with the other Credit Documents represent
the entire agreement of the parties hereto and thereto, and supersede all prior
agreements and understandings, oral or written, if any, including any commitment
letters or correspondence relating to the Credit Documents or the transactions
contemplated herein and therein.

          11.13    BINDING EFFECT; TERMINATION.

          (a)      This Credit Agreement shall become effective at such time
     on or after the Closing Date when it shall have been executed by the
     Borrower, the Guarantors and the Agent, and the Agent shall have received
     copies hereof (telefaxed or otherwise) which, when taken together, bear the
     signatures of each Lender, and thereafter this Credit Agreement shall be
     binding upon and inure to the benefit of the Borrower, the Guarantors, the
     Agent and each Lender and their respective successors and assigns.

          (b)      The term of this Credit Agreement shall be until no
     Loans, LOC Obligations or any other amounts payable hereunder or under any
     of the other Credit Documents shall remain outstanding, no Letters of
     Credit shall be outstanding, all of the Credit Party Obligations have been
     irrevocably satisfied in full and all of the Commitments hereunder shall
     have expired or been terminated.

          11.14    SOURCE OF FUNDS.

     Each of the Lenders hereby represents and warrants to the Borrower that at
least one of the following statements is an accurate representation as to the
source of funds to be used by such Lender in connection with the financing
hereunder: 

          (a)      no part of such funds constitutes assets allocated to any
     separate account maintained by such Lender in which any employee benefit
     plan (or its related trust) has any interest;

                                       111

<PAGE>

          (b)    to the extent that any part of such funds constitutes
     assets allocated to any separate account maintained by such Lender, such
     Lender has disclosed to the Borrower the name of each employee benefit plan
     whose assets in such account exceed 10% of the total assets of such account
     as of the date of such purchase (and, for purposes of this subsection (b),
     all employee benefit plans maintained by the same employer or employee
     organization are deemed to be a single plan);

          (c)    to the extent that any part of such funds constitutes
     assets of an insurance company's general account, such insurance company
     has complied with all of the requirements of the regulations issued under
     Section 401(c)(1)(A) of ERISA; or

          (d)    such funds constitute assets of one or more specific
     benefit plans which such Lender has identified in writing to the Borrower. 

As used in this Section 11.15, the terms "employee benefit plan" and "separate
account" shall have the respective meanings assigned to such terms in Section 3
of ERISA.

          11.15  CONFLICT.

     To the extent that there is a conflict or inconsistency between any
provision hereof, on the one hand, and any provision of any Credit Document, on
the other hand, this Credit Agreement shall control.

     11.16     CONFIDENTIALITY.

     The Agent and each Lender (each, a "LENDING PARTY") agrees to keep
confidential any information furnished or made available to it by the Borrower
pursuant to this Credit Agreement that is marked confidential; PROVIDED that
nothing herein shall prevent any Lending Party from disclosing such information
(a) to any other Lending Party or any Affiliate of any Lending Party, or any
officer, director, employee, agent, or advisor of any Lending Party or Affiliate
of any Lending Party, (b) to any other Person if reasonably incidental to the
administration of the credit facility provided herein, (c) as required by any
law, rule, or regulation, (d) upon the order of any court or administrative
agency, (e) upon the request or demand of any regulatory agency or authority,
(f) that is or becomes available to the public or that is or becomes available
to any Lending Party other than as a result of a disclosure by any Lending Party
prohibited by this Credit Agreement, (g) in connection with any litigation to
which such Lending Party or any of its Affiliates may be a party, (h) to the
extent necessary in connection with the exercise of any remedy under this Credit
Agreement or any other Credit Document, and (i) subject to provisions
substantially similar to those contained in this Section 11.16, to any actual or
proposed participant or assignee; PROVIDED, HOWEVER, that in the event that any
Lending Party is requested to disclose any confidential information pursuant to
clause (c), (d), (e) or (g) above, then such Lending Party shall, to the extent
lawfully permitted, use reasonable best efforts to promptly notify the Borrower.

     expenses in connection with, Permitted Acquisitions and Permitted Capital
     Expenditures; PROVIDED, HOWEVER, that the sum of the aggregate principal
     amount of outstanding Acquisition Loans shall not exceed FIFTY MILLION

     with a single Interest Period.  Acquisition Loans, other than any term
     portion of the Acquisition Loans,  hereunder may be repaid and reborrowed
     in accordance with the provisions hereof.
