                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
              (dollars in thousands, except as otherwise indicated)

1.       Basis of Presentation

         We have prepared the accompanying unaudited interim consolidated
financial statements of Advanced Glassfiber Yarns LLC 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 accounting
principles generally accepted in the United States 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 nine months ended September 30, 2000
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.

         AGY Capital Corp. is a wholly owned subsidiary of Advanced Glassfiber
Yarns LLC, formed solely to facilitate our offering of 9 7/8% Senior
Subordinated Notes due 2009. Separate financial statements or 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.

         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, 1999 in our 1999 Annual Report on Form 10-K.

6.  Subsequent Events

          On October 5, 2000, Owens Corning, which owns a 49% economic interest
in Advanced Glassfiber Yarns, and certain of Owens Corning's United States
subsidiaries (collectively, the "Debtors") filed voluntary petitions with the
United States Bankruptcy Court for the District of Delaware seeking relief under
Chapter 11 of the United States Bankruptcy Code. According to filings made by
Owens Corning with the SEC, the Debtors will continue to manage their properties
and operate their businesses as "debtors-in-possession" in accordance with the
applicable provisions of the United States Bankruptcy Code. As a result of our
ongoing supply agreements with Owens Corning, we have certain receivables due
from Owens Corning as of September 30, 2000. Additionally, as a part of the
supply agreements with Owens Corning, we have certain trade payables due to
Owens Corning as of the same date. Although no assurances can be provided, we do
not believe that Owens Corning's bankruptcy will have a material adverse effect
on our business, financial condition or results of operations. However, this
forward-looking statement is subject to risks and uncertainties that exist in
our operations and our business environment. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations - Disclosure Regarding
Forward-Looking Statements."

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 "Cautionary Statement 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 financial statements and related notes, and
with our audited consolidated financial statements as of the year ended December
31, 1999 and related notes set forth in our 1999 Annual Report on Form 10-K.

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 for 72.9% of our net sales during the
              nine months ended September 30, 1999 and 73.0% of our net sales
              during the nine months ended September 30, 2000; and
         o    fine yarns, which accounted for 27.1% of our net sales during the
              nine months ended September 30, 1999 and 27.0% of our net sales
              during the nine months ended September 30, 2000.

          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.

Adjusted EBITDA for the quarter ended September 30, 2000 increased $0.3 million,
or 1.8%, to $17.2 million from $16.9 million for the quarter ended September 30,
1999 and for the nine months ended September 30, 2000 increased $1.6 million, or
3.0%, to $54.2 million from $52.6 million for the same period in 1999.

         We believe that adjusted EBITDA is a widely accepted financial
indicator of a company's ability to service and/or incur indebtedness. Adjusted
EBITDA does not represent and should not be considered as an alternative to net
income or cash flow from operations as determined by generally accepted
accounting principles, and adjusted EBITDA does not necessarily indicate whether
cash flow will be sufficient for cash requirements. Not every company calculates
adjusted EBITDA in exactly the same fashion. As a result, adjusted EBITDA as
presented above may not necessarily be comparable to similarly titled measures
of other companies.

Three Months Ended September 30, 2000 Compared to Three Months Ended September
30, 1999

         Net Sales. Net sales increased $5.2 million, or 8.2%, to $68.8 million
in the three months ended September 30, 2000 from $63.6 million in the three
months ended September 30, 1999. Excluding the impact of changes in the exchange
rate of European currencies, third quarter 2000 net sales would have been $7.0
million higher than in the third quarter of 1999. This sales growth reflected a
higher demand primarily in the construction and electrical markets, for which
sales increased by 31.1% and 9.1%, respectively.

         Gross Profit. Gross profit is relatively stable at 26.2% of net sales
for the three months ended September 30, 2000 compared to the same period in
1999. Excluding the impact of changes in the exchange rate of European
currencies, gross profit in the third quarter of 2000 would have been 26.7%.
This improvement was primarily due to higher volumes sold resulting in more
absorption of fixed costs but was partially offset by a recent rise in energy
costs.

         Selling, General and Administrative Expenses. The expense associated
with selling, general and administrative costs remained flat for the three
months ended September 30, 2000 as compared to the same period for 1999. When
expressed as a percentage of net sales, this expense decreased to 5.8% for the
quarter ended September 30, 2000 as compared to 6.1% for the same period in
1999. This decrease was due to increased sales during the third quarter of 2000.

         Operating Income. As a result of the aforementioned factors, operating
income increased $1.4 million to $11.2 million, or 16.3% of net sales, for the
three months ended September 30, 2000 from $9.8 million, or 15.4% of net sales,
for the three months ended September 30, 1999.

         Interest Expense. Interest expense decreased $0.4 million to $8.8
million in the three months ended September 30, 2000 from $9.2 million in the
three months ended September 30, 1999. The decrease was a result of reductions
in the principal amount outstanding under our senior credit facility, partially
offset by an increase in accrued interest on a deferred distribution to a
member, as well as the cost of foreign currency hedging programs.

         Other Income/Expense, net. The quarter-to-quarter $1.0 million decrease
in other income/expense is primarily attributable to an increase of $0.9 million
in alloy metal leasing

                                       10
<PAGE>
expense, as well as a decrease of $0.3 million in interest income, which was
partially offset by a $0.2 million increase in royalty income as compared to the
same quarter of 1999.

         Net Income. As a result of the aforementioned factors, net income
increased $0.7 million to $2.0 million in the three months ended September 30,
2000, from $1.3 million in the three months ended September 30, 1999.

Nine Months Ended September 30, 2000 Compared to Nine Months Ended September 30,
1999

         Net Sales. Net sales increased $20.8 million, or 11.1%, to $208.0
million in the nine months ended September 30, 2000 from $187.2 million in the
nine months ended September 30, 1999. The net increase in sales resulted from a
higher demand primarily in the electrical and construction markets, for which
sales increased by 24.6% and 15.3%, respectively. This was partially offset by
a 12.5% decline of European currencies in the first nine months of 2000 as
compared to the same period in 1999, as well as selling price erosions that
occurred throughout 1999. Recent price increase continue to move towards the
historical pricing level of early 1999.

         Gross Profit. Gross profit decreased from 28.1% of net sales for the
nine months ended September 30, 1999 to 26.6% of net sales for the nine months
ended September 30, 2000. Excluding the impact of changes in the exchange rate
of European currencies, gross profit in the first nine months of 2000 would have
been 27.3%. The positive impact of higher volumes sold for all categories of
yarns, was partially offset by the residual effect of the 1999 selling price
erosions, additional startup manufacturing costs related to increases in
capacity in the first quarter of 2000, as well as recent increases in energy
costs.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses decreased to 5.9% of net sales for the nine months ended
September 30, 2000 as compared to 6.7% of net sales for the nine months ended
September 30, 1999. This decrease, which was primarily attributable to an
increase in sales during the first nine months of 2000, was partially offset by
an increase in depreciation of the information systems established in 1999.

         Operating Income. As a result of the aforementioned factors, operating
income increased $2.8 million to $34.4 million, or 16.5% of net sales, for the
nine months ended September 30, 2000 from $31.6 million, or 16.9% of net sales,
for the nine months ended September 30, 1999.

         Interest Expense. Interest expense decreased $0.3 million to $27.0
million in the nine months ended September 30, 2000 from $27.3 million in the
nine months ended September 30, 1999. The decrease was a result of reductions in
the principal amount outstanding under our senior credit facility term loans,
partially offset by higher revolver borrowings in the nine months ended
September 30, 2000 as compared to the same period in 1999. The decrease was
partially offset by an increase in accrued interest on a deferred distribution
to a member as well as the cost of foreign currency hedging programs.

                                       11
<PAGE>
         Other Income/Expense, net. The period-to-period $0.6 million decrease
in other income/expense primarily reflects $1.3 million of additional royalty
income partially resulting from the recent settlement of $0.8 million for
disputed royalties with our licensee, as well as $0.3 million reduced foreign
currency losses due to hedging, partially offset by an increase of $1.9 million
in alloy metal leasing expense and a decrease in interest income of $0.5 million
as compared to the same period in 1999.

         Net Income. As a result of the aforementioned factors and the $3.6
million loss on early extinguishment of debt which occurred in 1999, net income
increased $6.0 million to $7.8 million in the nine months ended September 30,
2000, from $1.8 million in the nine months ended September 30, 1999.

Liquidity and Capital Resources

         Our primary sources of liquidity are cash flows from operations,
borrowings under the senior credit facility and the issuance of our 9 7/8%
senior subordinated notes due 2009. Our future liquidity requirements will
generally include funding principal payments on our senior credit facility,
interest payments, capital expenditures and working capital requirements. We
have no mandatory payments of principal on our senior subordinated notes prior
to their maturity.

           At September 30, 2000, we had outstanding $345.1 million of long-term
debt at a weighted average interest rate of 8.9%, consisting of $197.6 million
under our senior credit facility, $147.3 million under our 9 7/8% senior
subordinated notes (net of discount of $2.7 million) and $0.2 million of capital
leases, less a current portion of $19.8 million. The amounts outstanding under
our senior credit facility included $13.6 million outstanding under a revolver.
As of September 30, 2000, we had approximately $50.0 million of availability
under the revolver.

           Net Cash Provided by Operating Activities. Net cash provided by
operating activities was $26.9 million for the nine months ended September 30,
2000 and was primarily the result of net income of $7.8 million, non-cash
adjustments of $22.1 million, a decrease in accounts receivable, inventory,
accounts payable and the liability due to Owens Corning of $2.9 million, $3.4
million, $3.7 million and $4.8 million, respectively, as well as an increase in
accrued liabilities of $0.2 million.

         Net Cash Used in Investing Activities. Net cash used in investing
activities was $9.5 million for the nine months ended September 30, 2000 and was
mainly the result of purchases of property, plant and equipment, net of the
proceeds from the sale of fixed assets.

         We have historically financed our capital expenditures through cash
flow from operations and borrowings under our senior credit facility. For the
nine months ended September 30, 2000, capital expenditures were $13.4 million,
excluding assets associated with a sale and leaseback transaction during the
second quarter of 2000 pursuant to which we sold manufacturing

                                       12
<PAGE>
equipment for net proceeds of approximately $3.9 million. We are anticipating
total capital expenditures in 2000 to be approximately $20.0 million, including
assets associated with the sale and leaseback transaction.

         Net Cash Used in Financing Activities. Net cash used in financing
activities was $18.9 million for the nine months ended September 30, 2000 and
was primarily the result of the repayment of principal amounts outstanding under
our senior credit facility and distribution of a dividend payable to a member.

         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 and the payment of tax
distributions.

         We derived 21.0% of our net sales in the third quarter of 2000 from
products sold in currencies other than the US dollar. The US dollar value of our
export sales sometimes varies with currency exchange rate fluctuations. We may
therefore be exposed to exchange losses as a result of such fluctuations that
could reduce our net income. We have adopted a risk management strategy to use
derivative financial instruments including forwards and options to hedge foreign
currency exposures. See "Quantitative and Qualitative Disclosures About Market
Risk." However, we cannot assure you that any such hedging agreements will be
sufficient to eliminate risks relating to currency fluctuations.


Recent Developments

         Impact of Owens Corning's Bankruptcy. On October 5, 2000, Owens
Corning, which owns a 49% economic interest in Advanced Glassfiber Yarns, and
certain of Owens Corning's United States subsidiaries (collectively, the
"Debtors") filed voluntary petitions with the United States Bankruptcy Court for
the District of Delaware seeking relief under Chapter 11 of the United States
Bankruptcy Code. According to filings made by Owens Corning with the SEC, the
Debtors will continue to manage their properties and operate their businesses as
"debtors-in-possession" in accordance with the applicable provisions of the
United States Bankruptcy Code. Although no assurances can be provided, we do not
believe that Owens Corning's bankruptcy will have a material adverse effect on
our business, financial condition or results of operations. However, this
forward-looking statement is subject to risks and uncertainties that exist in
our operations and our business environment. See " - Disclosure Regarding
Forward-Looking Statements."

                                       13

      Proposed Transaction Between Our Two Members. We previously reported that
Porcher Industries Group and Owens Corning executed a memorandum of
understanding setting forth the general parameters pursuant to which Porcher
Industries Group intended to purchase Owens Corning's 49% economic interest in
Advanced Glassfiber Yarns. Due to Owens Corning's recent bankruptcy filing, we
cannot assure you that this transaction will ever be consummated or that it will
be consummated on the terms previously disclosed. In addition, consummation of
such a transaction would be subject to factors outside our control, including,
among other things, the execution of definitive agreements, our ability to
obtain any required lender consents and other approvals, and Porcher Industries
Group's ability to obtain satisfactory financing. If Porcher Industries Group
acquires Owens Corning's 49% economic interest, we may be required to step up
the value of certain assets from Owens Corning's historical book value to fair
market value as of the date of the transaction. This could result in the
recording of additional depreciation and amortization expense and the payment of
additional property taxes, which would reduce our future net income.


Recently Issued Accounting Standard

      On September 8, 1999, the Financial Accounting Standards Board issued SFAS
No. 138, "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 September 15, 2000. SFAS 133, as amended by SFAS 138, 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 use derivative instruments from time to time to reduce our
exposure to fluctuations in interest rates and foreign currency exchange rates.
We are currently evaluating this Statement and its prospective impact on our
consolidated financial statements. We are in the process of evaluating the
affect it will have on our financial statements. We will be required to
implement Statement 133 in the first quarter of 2001.


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:

                                       14

         o        our significant level of indebtedness and limitations on our
                  ability to incur additional debt;
         o        the impact of Owens Corning`s unpredictable bankruptcy
                  proceeding on our financial condition and ongoing operations;
         o        the risk that obtaining raw materials and capital equipment
                  services from sources other than Owens Corning would be more

                  processes;
         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;

                  laws and requirements; and
         o        changes in economic conditions generally.

         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 1999 Annual Report on Form 10-K. 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 currency exchange rates and
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 and currency exchange 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 are exposed to foreign currency exchange rate risk
mainly as a result of our export sales. Our risk management strategy is to use
derivative financial instruments, including forwards, swaps and purchased
options, to hedge foreign currency and interest rate exposures. Our objective is
to limit the impact of currency and interest rate changes on earnings and cash
flows. We do not enter into derivatives for trading or speculative purposes.

         As of September 30, 2000, the notional value of our interest rate swaps
was $189.0 million, equal to the outstanding borrowings under Term Loans A and B
of our senior credit facility and $5.0 million under the revolver portion of our
senior credit facility. The fair value of the interest rate swap agreement
represents the estimated receipts or payments that would be made to terminate
the agreements. At September 30, 2000, we would have received approximately $9.1
million to terminate the agreements. A 100 basis point decrease in LIBOR would
decrease the amount received by approximately $3.9 million. The fair value is
based on dealer quotes, considering current interest rates.

         As of September 30, 2000, the notional value of our foreign currency
hedging instruments was $7.3 million, and the approximate fair value was $0.5
million. The potential loss in fair value of such financial instruments from a
hypothetical 10% decrease in the underlying exchange rates relative to the US
dollar would be approximately $0.4 million as of September 30, 2000. The
potential gain in the fair value of such financial instruments from a
hypothetical 10% increase in the underlying exchange rates relative to the US
dollar would be approximately $0.6 million as of September 30, 2000. The fair
value is based on dealer quotes, considering current exchange rates.

         Actual gains and losses in the future may differ materially from that
analysis, however, based on changes in the timing and amount of interest rate
and foreign currency exchange rate movements and our actual exposures and
hedges. In addition, we are exposed to losses in the event of nonperformance by
the counterparties under the interest rate swap agreements or foreign currency
hedging instruments. We expect the counterparties, which are major financial
institutions, to perform fully under these contracts. However, if the
counterparties were to default on their obligations under the agreements, we
could lose any benefits contractually accruing in our favor as a result of
market changes in interest or foreign currency exchange rates.
