              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                  JUNE 30, 1999
                                   (UNAUDITED)

1.   BASIS OF PRESENTATION

         Advanced Glassfiber Yarns LLC (the "Consolidated Company") is a
Delaware limited liability company initially formed by Owens Corning to own and
operate Owens Corning's glass yarns and specialty materials business (the
"Predecessor Business"). On July 1, 1998, Owens Corning contributed
substantially all of the assets and liabilities of the Predecessor Business to
the Consolidated Company. On September 30, 1998, Owens Corning sold a 51%
interest in Advanced Glassfiber Yarns to a wholly owned subsidiary of Porcher
Industries. Owens Corning retained the remaining 49% interest. Accordingly, the
historical financial information for the three and six months ended June 30,
1998 is based upon the historical financial information of the business as it
was operated by Owens Corning.

         AGY Capital Corp. is a wholly owned subsidiary of Advanced Glassfiber
Yarns, formed solely to facilitate our offering of 9 7/8% Senior Subordinated
Notes due 2009. Separate financial statements or condensed consolidating
financial data of AGY Capital Corp. are not presented because management has
determined that they are not material. AGY Capital Corp. has no assets or
operations.

         We have prepared the accompanying unaudited interim consolidated
condensed financial statements in accordance with the instructions to Form 10-Q
and Rule 10-01 of Regulation S-X, and accordingly, they do not include all of
the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments (consisting of items of a normal recurring nature) considered
necessary for a fair presentation have been included. Operating results for the
six months ended June 30, 1999 are not necessarily indicative of the results to
be expected for the full year. We believe that the disclosures are adequate to
make the information presented not misleading. The historical financial
statements of the Predecessor Business were derived from the historical
financial statements of Owens Corning.

         These financial statements should be read in conjunction with the
audited consolidated financial statements of Advanced Glassfiber Yarns LLC as of
and for the year ended December 31, 1998 on file with the SEC in our
Registration Statement on Form S-4 (SEC File No. 333-72305) that was declared
effective on June 21, 1999.

         On June 30, 1999, we paid off $5.0 million of the principal amount of
one of the term loans prior to its scheduled payment. In addition, we terminated
the portion of the interest rate swap agreement related to this principal
repayment and recorded a gain of $0.3 million. Such gain was netted against
interest expense in the accompanying financial statements.

5.   OTHER TRANSACTIONS

         On January 21, 1999, we issued $150.0 million of 9 7/8% Senior
Subordinated Notes due 2009 ($147.0 million net of discount). Interest is
payable semiannually beginning in July 1999. Net proceeds of approximately
$141.9 million plus additional borrowings under our revolving credit facility
were used to repay $150.0 million outstanding under our senior subordinated
credit facility. In addition, debt issuance costs of $3.6 million associated
with the termination of our senior subordinated credit facility were written off
in the first quarter of 1999, and are classified as extraordinary charges.

         On June 21, 1999, the SEC declared effective our Registration Statement
on Form S-4 relating to our offering of $150.0 million of 9 7/8% Series B Senior
Subordinated Notes due 2009. These notes were issued on July 23, 1999 in
exchange for our 9 7/8% Senior Subordinated Notes due 2009 that were privately
issued on January 21, 1999. These new notes are substantially identical to the
old notes that we issued on January 21, 1999, except for the elimination of
transfer restrictions, registration rights and liquidated damages provisions
relating to the old notes.

         During the six months ended June 30, 1999, selling, general and
administrative expenses and relocation costs included approximately $1.4 million
in nonrecurring consulting expenses and relocation costs. During this same
period, we recorded a distribution to our members of $3.2 million. As a result,
at June 30, 1999, the balance sheet reflects a deferred distribution of $1.6
million to Porcher Industries.

         On June 8, 1999, we formed AGY Europe, SARL, a wholly owned subsidiary
located in Lyon, France. This subsidiary provides administrative and managerial
support for our European operations.

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

         This Quarterly Report contains certain forward-looking statements with
respect to our operations, industry, financial condition and liquidity. These
statements reflect our assessment of a number of risks and uncertainties. Our
actual results could differ materially from the results anticipated in these
forward- looking statements as a result of certain factors set forth in this
Quarterly Report. An additional statement made pursuant to the Private
Securities Litigation Reform Act of 1995 and summarizing certain of the
principal risks and uncertainties inherent in our business is included herein
under the caption "Disclosure Regarding Forward-Looking Statements." You are
encouraged to read this section carefully.

         You should read the following discussion and analysis in conjunction
with the accompanying consolidated condensed financial statements and related
notes, and with our audited consolidated financial statements as of the year
ended December 31, 1998 set forth in our Registration Statement.

OVERVIEW

         Our business focuses on the production of glass yarn by converting
molten glass into thin filaments, which are then twisted into yarn. Our products
fall into two categories based on filament diameter:
o    heavy yarns, which accounted respectively for 75% and 73% of our first half
     year 1998 and 1999 net sales; and
o    fine yarns, which accounted respectively for 25% and 27% of our first half
     year 1998 and 1999 net sales;

         We believe that we are the world's largest producer of fine yarns, and
the world's second largest producer of heavy yarns. Glass yarns are a critical
material used in a variety of electronic, industrial, construction and specialty
applications such as printed circuit boards, roofing materials, filtration
equipment, building reinforcement, window screening, aerospace materials,
sporting goods and vehicle armor.

</TABLE>

THREE MONTHS ENDED JUNE 30, 1999 COMPARED TO THREE MONTHS ENDED JUNE 30, 1998

         NET SALES. Net sales decreased $6.1 million, or 9.0%, to $61.6 million
in the three months ended June 30, 1999 from $67.7 million in the three months
ended June 30, 1998. This decrease was due primarily to decreased demand for
heavy yarns used in rigid printed circuit boards as well as reduced sales in the
construction industries. The decrease was partially offset by increased sales
for industrial and specialty applications. Our sales in Europe in the second
quarter of 1999 were also adversely affected by depreciation of European
currencies compared to the first quarter of 1998.

         GROSS PROFIT. Gross profit margins decreased from 36.0% for the three
months ended June 30, 1998 to 27.8% for the three months ended June 30, 1999.
This decrease is attributable to price pressure on the electrical market and to
the weakening of European currencies. Additionally, fabrication costs increased
due to the supply agreement with Owens Corning in effect during 1999 and
depreciation costs increased compared to the comparable period in 1998 due to
the step-up of fixed assets associated with the purchase by Porcher Industries
of a 51% interest in Advanced Glassfiber Yarns. These changes have been
partially offset by a more favorable higher margin product mix as well as a
decrease in labor costs resulting from a personnel reduction at our Huntingdon
and Aiken facilities.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased to 7.6% from 5.6% of net sales for the three
months ended June 30, 1999 and 1998, respectively. This was primarily due to the
establishment of independent operational, management and information system
controls in connection with the formation transactions and a decrease in sales.

                                       10
<PAGE>
         INCOME FROM OPERATIONS. As a result of the aforementioned factors and
amortization of goodwill of $2.8 million, income from operations decreased $11.0
million to $9.6 million, or 15.6% of net sales, for the three months ended June
30, 1999, from $20.6 million, or 30.4% of net sales, for the three months ended
June 30, 1998.

SIX MONTHS ENDED JUNE 30, 1999 COMPARED TO SIX MONTHS ENDED JUNE 30, 1998

         NET SALES. Net sales decreased $17.0 million, or 12.1%, to $123.6
million in the six months ended June 30, 1999 from $140.6 million in the six
months ended June 30, 1998. This decrease was due primarily to decreased demand
for heavy yarns used in rigid printed circuit boards as well as reduced sales in
the construction industries. The decrease was partially offset by increased
sales for industrial and specialty applications.

         GROSS PROFIT. Gross profit margins decreased from 35.0% for the six
months ended June 30, 1998 to 30.0% for the six months ended June 30, 1999. This
decrease is attributable to price pressure on the electrical market.
Additionally, fabrication costs increased due to the supply agreement with Owens
Corning in effect during 1999 and depreciation costs increased compared to the
comparable period in 1998 due to the step-up of fixed assets associated with the
purchase by Porcher Industries of a 51% interest in Advanced Glassfiber Yarns.
These changes have been partially offset by a more favorable higher margin
product mix as well as a decrease in labor costs resulting from a personnel
reduction at our Huntingdon and Aiken facilities.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased to 7.9% from 5.5% of net sales for the six
months ended June 30, 1999 and 1998, respectively. This was primarily due to the
establishment of independent operational, management and information system
controls in connection with the formation transactions and a decrease in sales.

         INCOME FROM OPERATIONS. As a result of the aforementioned factors and
amortization of goodwill of $5.7 million, income from operations decreased $17.8
million to $21.7 million, or 17.5% of net sales, for the six months ended June
30, 1999, from $39.5 million, or 28.1% of net sales, for the six months ended
June 30, 1998.

LIQUIDITY AND CAPITAL RESOURCES

         Historically, our primary sources of liquidity were cash flows from
operations. Since the consummation of the formation transactions, our primary
sources of liquidity have been cash flows from operations and borrowings under
the senior credit facility. Our principal uses of liquidity are to fund
operations, service debt, including interest payments, and finance our planned
capital expenditures, including the purchase of new management information
systems for our headquarters at the Aiken facility.

         For the six months ended June 30, 1999, net cash provided by operating
activities decreased $12.7 million from $25.6 million for 1998 to $12.9 million
for 1999. The decrease was primarily attributable to a reduction of net income,
before extraordinary item and depreciation and amortization of $12.1 million, a
decrease in accounts payable of $5.5 million, an increase in inventory of $1.4
million and an increase in accounts receivable of $0.4 million, offset by an
increase in accrued liabilities of $3.7 million and an increase in pension and
post-retirement liability of $1.9 million.

                                       11
<PAGE>

         In connection with the formation transactions, we entered into a senior
credit facility, which provides for:

         o  a six-year revolver in an aggregate principal amount of up to $75.0
            million, which includes a $10.0 million swing line sub-facility and
            a $30.0 million letter of credit sub-facility;

         o  a seven-year term loan in an aggregate principal amount of $125.0
            million; and

         o  a six-year term loan in an aggregate principal amount of $115.0
            million.

First Union National Bank serves as agent under the senior credit facility. The
senior credit facility is collateralized by a first priority lien on
substantially all of our properties and assets and by a pledge of Porcher
Industries' interest in Advanced Glassfiber Yarns. As of June 30, 1999, $225.4
million was outstanding under the senior credit facility and we had availability
thereunder equal to approximately $74.5 million.

         On January 21, 1999, we privately issued $150.0 million of 9 7/8%
Senior Subordinated Notes due 2009. Our net proceeds from the sale of these
notes were approximately $141.9 million, after deducting the initial purchasers'
discount and expenses of the offering. We used the net proceeds from the
offering, together with additional borrowings under our senior credit facility,
to repay all debt outstanding under a $150.0 million senior subordinated credit
facility, which was incurred on September 30, 1998 in connection with the
formation transactions. On July 23, 1999, we exchanged the notes for
substantially identical new notes that have been registered under the Securities
Act of 1933. Interest expense on an as adjusted pro forma basis, after giving
effect to the formation transactions, the sale of the notes and the subsequent
exchange of the notes, was $38.7 million for 1998 and $18.3 million for the six
months ended June 30, 1999. We expect to fund the interest payments on the notes
with operating cash flows.

         We have historically financed our capital expenditures through cash
flow from operations. Capital expenditures, including capital leases, were $4.2
million for the six months ended June 30, 1999. We expect to make annual capital
expenditures aggregating approximately $18.0 million in 1999. We anticipate that
capital expenditures incurred in 1999 will be made for routine maintenance and
rebuilds of glass melting furnaces and other equipment upgrades used in our
operations. We also intend to spend approximately $3.3 million for our new year
2000 compliant management information systems in 1999. In addition, we are
currently exploring the feasibility of constructing a new melter at our Aiken
facility. In the event that we construct this melter, we believe the overall
costs would be approximately $49.0 million; however, in connection with the
construction of the melter, we believe we would reduce expenses associated with
the rebuild of furnaces by approximately $12.0 million. We cannot assure you
that such a new melter will be constructed or, if constructed, that the
projected cost of construction or the associated reduction of expenses will
prove to be accurate.

                                       12
<PAGE>
         Our ability to make scheduled payments of principal of, or to pay the
interest or liquidated damages, if any, on, or to refinance, our indebtedness,
or to fund planned capital expenditures will depend on our future performance,
which is generally subject to economic, financial, competitive, legislative,
regulatory and other factors that are beyond our control. Based upon the current
level of operations, we believe that cash flows from operations and available
cash, together with availability under the senior credit facility, will be
adequate to meet our future liquidity needs for at least the next two years.
However, we cannot assure you that our business will generate sufficient cash
flows from operations or that future borrowings will be available under the
senior credit facility in an amount sufficient to enable us to service our
indebtedness, or to fund our other liquidity needs, including the possible
construction of a new melter at our Aiken facility and the payment of tax
distributions.

YEAR 2000

         STATE OF READINESS. At the beginning of 1998, the management of our
information systems and research and development groups began to assess the year
2000 issue. These persons have developed and are currently implementing a
comprehensive year 2000 compliance program to make our IT and non-IT assets year
2000 compliant. Our IT assets are primarily used in the delivery of our products
and services, and are also used in our internal operations, such as billing and
accounting. Our non-IT assets are primarily micro-processor based process
control systems used in the manufacture of our products.

         Our year 2000 compliance program consists of the following phases:

o        Phase One-Assessment
         ---------------------
         Establish year 2000 program team. Identify core business areas,
         processes and systems and determine their ability to operate properly
         when post-1999 dates are introduced.

o        Phase Two-Develop Remediation Plan
         -----------------------------------
         Identify appropriate remedial action or system replacement for each
         identified system that is not year 2000 compliant.

                                       13
<PAGE>
o        Phase Three-Develop Implementation Plans and Contingency Plans; Testing
         -----------------------------------------------------------------------
         Develop implementation plans for remedial actions or systems
         replacements and develop contingency plans to handle data exchange and
         bad data. Identify and secure necessary resources. Test and verify
         upgraded, converted or replacement systems.

o        Phase Four-Implementation
         --------------------------
         Perform remedial actions and systems replacements.

         The following table summarizes our progress to date under our year 2000
compliance program:

                      replace some of these systems to complete
                      our separation from Owens Corning's
                      computer systems.

Phase Three           Substantially completed. Estimated                 Substantially completed. Estimated
                      completion is September 30, 1999.                  completion is October 31, 1999.

</TABLE>

         During the second phase of the year 2000 compliance program, we
identified several key IT and non-IT systems that need to be replaced in order
to become year 2000 compliant. The IT systems to be replaced include all
financial and order entry/planning systems and the non-IT systems to be replaced
include various process control systems. Replacement of our financial and order
entry/planning systems is also necessary to complete the separation from Owens
Corning's computer systems. Of the 17 process control systems that were
evaluated, two were identified as having compliance issues sufficient to warrant
total system replacement. We have begun implementation and internal testing of
these replacement systems and are targeting completion by October 31, 1999. The
systems that will not be replaced will be upgraded to become year 2000 compliant
on the same schedule as the system replacements. Upgrading these systems
generally requires less resources than total system replacement. As replacement
of some of our

                                       14
<PAGE>
systems was contemplated with our separation from Owens Corning, we have
deferred no material IT projects due to our year 2000 efforts.

         In addition to internal systems, we are dependent on external
suppliers, including Owens Corning, for the delivery of raw materials, energy
and supplies. We have contacted approximately 200 of our top external suppliers,
who represent approximately 90% of our total purchases, to evaluate their year
2000 compliance plans and state of readiness and determine whether a year
2000-related event will impede the ability of our suppliers to continue to
provide us goods and services. Approximately 85% of these suppliers have
responded that they are or expect to be year 2000 compliant. Although we have
not received responses from 15% of our suppliers and will follow-up with them by
the third quarter of 1999, we believe that even if non-responsive suppliers
experience business disruption due to year 2000 it will not have a material
effect on our business operations. We believe that our key suppliers are
sufficiently aware of year 2000 issues and are taking actions to remediate any
problems. However, we cannot assure you that our key suppliers will not suffer a
year 2000 business disruption and we have used no independent verification or
validation process to evaluate such risks. We could suffer business disruptions
and loss of revenue if our material suppliers fail to supply goods and services
necessary for our operations.

      Of our top ten customers, who represent approximately 68% of our sales as
of June 30, 1999, our two largest customers and two others have inquired of our
year 2000 state of readiness and we have responded to these inquiries. Other
than in connection with our relationship with Owens Corning, we have taken no
steps to determine the year 2000 readiness status of our customers. If a
sufficient number of our material customers were unable to receive or take
delivery of our products due to year 2000 problems, we would suffer business
disruptions and loss of revenue.

         COSTS TO ADDRESS THE YEAR 2000 ISSUE. As of June 30, 1999, we had spent
approximately $1.8 million in software and external consulting costs to address
the year 2000 issue. We estimate that our year 2000 compliance program,
including the cost of new hardware and software for new systems, will cost
approximately $3.3 million, including the cost to establish and test the
independent replacement computer systems discussed above, excluding the cost of
internal personnel. We expect to spend an estimated $1.1 million in the third
quarter of 1999 and approximately $0.4 million in the fourth quarter of 1999.
Approximately 10% of the total projected costs are projected to be spent on
systems repair and modification and 90% on the referenced system replacements.
We expect to capitalize approximately $1.7 million of these costs and we intend
to fund these costs from cash flow from operations.

      RISKS PRESENTED BY THE YEAR 2000 ISSUE. We believe that we have identified
all material year 2000 issues and implemented a plan to address these issues
prior to any impact on business operations. However, failure to complete
remediation and replacement programs as scheduled could impact our ability to
properly manufacture goods and conduct normal business operations, which may
result in potential liability for failure to deliver product or other harm. If
this were to occur, we could experience a material adverse impact on our
financial condition and results of operations. Likewise, failure of key
suppliers or customers to achieve compliance could adversely impact our ability
to manufacture, distribute and sell products.

                                       15
<PAGE>
      CONTINGENCY PLANS. In the event that all of our systems are not made
compliant prior to the need to handle year 2000 dates, we have considered
alternatives to continue normal business operations. We anticipate that process
control systems that do not handle year 2000 dates properly can continue to
operate with some limitation in functions. These systems will be tested to
demonstrate this capability. With regard to information technology systems that
are critical to business operations, we believe that our remediation and
replacement program will sufficiently address year 2000 issues. However, we will
continue to evaluate our progress and create additional contingency plans as
necessary.

      The estimates and conclusions related to our year 2000 compliance program
contain forward-looking statements and are based on management's best estimates
of future events. Risks to completing the year 2000 compliance program include
the availability of resources, our ability to discover and correct the potential
year 2000 specific problems that could have a serious impact on specific
systems, equipment or facilities and the ability of suppliers and vendors and
other third parties to make their systems year 2000 compliant. Various of our
disclosures and announcements concerning year 2000 programs are intended to
constitute "Year 2000 Readiness Disclosures" as defined in the recently enacted
Year 2000 Information and Readiness Disclosure Act.

INTRODUCTION OF THE SINGLE EUROPEAN CURRENCY

      On January 1, 1999, eleven member states of the European Union-Austria,
Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, The Netherlands,
Portugal and Spain-introduced the Euro as a common legal currency among those
states for "paperless" transactions, pending the substitution of Euro banknotes
and coins for the national currencies of the participating member states. As of
that date, fixed exchange rates were introduced. It is anticipated that by July
1, 2002, the Euro will be the official legal tender for the participating member
states and that the national currencies of those member states will be withdrawn
from circulation.

         The introduction of the Euro has necessitated only minor changes in our
information technology and other systems in order to accommodate the use of the
Euro in corporate transactions and in financial reporting. Costs incurred in
connection with the conversion have been immaterial.

      Our management is informally reviewing the various ways in which the
introduction of the Euro will affect our business and competitive position. We
expect that the introduction of the Euro will result in greater market
efficiency and will foster a more competitive economic environment within and
among the participating member states. This is largely a function of the fact
that the pricing of products and services will be more transparent through the
use of a single common currency within the participating member states. While we
do not believe the Euro conversion will materially affect our operations,
particularly with respect to our sales in the participating member states, there
can be no assurance whether and to what extent the introduction of the Euro will
affect our business, financial condition and results of operations, or

                                       16
<PAGE>
whether we will be able to realize any strategic or operational benefits from
the introduction of the Euro.

      We intend to continue exploring various strategic and operational measures
with respect to the introduction of the Euro with a view to enhancing our
overall financial position, operating results and market position. These
strategic and operational options will be shaped to some extent by both European
and national rules and regulations regarding the particular measures required to
complete the transition to the Euro as the legal currency of the participating
member states.

RECENTLY ISSUED ACCOUNTING STANDARDS

      On June 9, 1999, the Financial Accounting Standards Board issued SFAS No.
137, "Deferral of the Effective Date of FAS 133," which changes the effective
date of FAS 133 to all fiscal quarters of all fiscal years beginning after June
15, 2000. SFAS 133 requires that all derivative instruments be recorded on the
balance sheet at their fair value. Changes in the fair value of derivatives are
recorded each period in current earnings or other comprehensive income,
depending on whether a derivative is designated as part of a hedge transaction
and, if it is, the type of hedge transaction. We anticipate that, due to our
limited use of derivative instruments, the adoption of SFAS 133 will not have a
significant effect on our results of operations or financial position.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

         Some of the information in this Quarterly Report may contain
forward-looking statements. These statements include, in particular, statements
about our plans, strategies and prospects within the meaning of Section 27A of
the Securities Act of 1933 and Section 21E of the Securities Exchange Act of
1934. You can identify forward-looking statements by our use of forward-looking
terminology such as "may," "will," "expect," "anticipate," "estimate,"
"continue" or other similar words. Although we believe that our plans,
intentions and expectations reflected in or suggested by such forward-looking
statements are reasonable, we cannot assure you that our plans, intentions or
expectations will be achieved. Such statements are based on our current plans
and expectations and are subject to risks and uncertainties that exist in our
operations and our business environment that could render actual outcomes and
results materially different from those predicted. When considering such
forward-looking statements, you should keep in mind the following important
factors that could cause our actual results to differ materially from those
contained in any forward-looking statements:

         o  our significant level of indebtedness and limitations on our ability
            to incur additional debt;
         o  our dependence upon Owens Corning to provide us with many materials
            and services;
         o  the risk of conflicts of interest with our equity holders;
         o  a downturn in the electronics industry and the movement of
            electronics industry production outside of North America;
         o  our concentrated customer base and the nature of our markets;
         o  a disruption of production at one of our facilities;
         o  foreign currency fluctuations;
         o  an easing of import restrictions and duties with respect to glass
            fabrics;
         o  failure by us or our suppliers or customers to address successfully
            year 2000 issues;
         o  labor strikes or stoppages;
         o  our ability to comply with environmental and safety and health laws
            and requirements; and
         o  changes in economic conditions generally.

                                       17

         This list of risks and uncertainties, however, is not intended to be
exhaustive. You should also review the other cautionary statements we make in
this Quarterly Report and in our Registration Statement on Form S-4 (SEC File
No. 333-72305) with respect to our 9 7/8% Senior Subordinated Notes due 2009,
especially the "Risk Factors" section of the Registration Statement. All
forward-looking statements attributable to us or persons acting for us are
expressly qualified in their entirety by our cautionary statements.

         We do not have, and expressly disclaim, any obligation to release
publicly any updates or changes in our expectations or any changes in events,
conditions or circumstances on which any forward looking statement is based.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The effects of potential changes in interest rates are discussed below.
Our market risk discussion includes "forward-looking statements" and represents
an estimate of possible changes in fair value that would occur assuming
hypothetical future movements in interest rates. These disclosures are not
precise indicators of expected future losses, but only indicators of reasonably
possible losses. As a result, actual future results may differ materially from
those presented. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations - Disclosure Regarding Forward-Looking
Statements."

         Our senior credit facility is subject to market risks, including
interest rate risk. Our financial instruments are not currently subject to
commodity price risk. We hold no financial instruments for trading or
speculative purposes.

         We are exposed to market risk related to changes in interest rates on
borrowings under our senior credit facility. The senior credit facility bears
interest based on LIBOR. Our interest rate risk management objective is to limit
the impact of interest rate changes on earnings and cash flows and to lower our
overall borrowing costs. To achieve these objectives, from time to time we enter
into interest rate swap agreements in order to mitigate our interest rate risk
with respect to indebtedness outstanding under the senior credit facility.

         We entered into an interest rate swap agreement to manage our exposure
to interest rate changes under the senior credit facility. The swap involves the
exchange of fixed and variable interest rate payments based on a contractual
principal amount and time period. Payments or receipts on the agreement are
recorded as adjustments to interest expense. At June 30, 1999, we had two
interest rate swap agreements effective through September 30, 2003 and 2005 on
an initial notional amount of $235 million, equal to the original borrowings
under Term Loans A and B under our senior credit facility. Under this agreement,
we have secured a fixed LIBOR rate of interest of 4.92% on the Term Loan A and
5.04% on the Term Loan B with an aggregate on the notional amount which is
reduced in a manner consistent with the amortization of the principal on our
term loans. This swap effectively changed our payment of interest on an average
of $240 million of variable rate debt for the contract period.

                                       18
<PAGE>
         The fair value of the interest rate swap agreement represents the
estimated receipts or payments that would be made to terminate the agreement. At
June 30, 1999, we would have received approximately $10.4 million to terminate
the agreements. A 1% decrease in LIBOR would decrease the amount received by
approximately $7.8 million. The fair value is based on dealer quotes,
considering current interest rates.

         In addition, we are exposed to losses in the event of nonperformance by
the counterparties under the interest rate swap agreements. We expect the
counterparties, which are major financial institutions, to perform fully under
these contracts. However, if the counterparts were to default on their
obligations under the interest rate swap agreements, we could be required to pay
the full rate on our senior credit facility, even if the rate was in excess of
the rates in the interest rate swap agreements.
