PROSPECTUS

                         ADVANCED GLASSFIBER YARNS LLC
                               AGY CAPITAL CORP.

                        Exchange Offer for $150,000,000
                  of 9 7/8% Senior Subordinated Notes due 2009

The Exchange Notes:

 . Advanced Glassfiber Yarns LLC and AGY Capital Corp. are joint and several
  obligors of the exchange notes. The terms of the exchange notes we issue will
  be substantially identical to the outstanding 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.

 . We will pay interest on the exchange notes twice a year, beginning July 15,
  1999.

 . We cannot redeem the exchange notes before January 15, 2004. After that date,
  we may redeem them at specified prices. However, before January 15, 2002, we
  can redeem up to 35% of the exchange notes at 110.125% of their face amount,
  plus interest, with money we raise in public equity offerings.

 . If we experience a change of control, we may be required to offer to purchase
  the exchange notes at 101% of their face amount, plus interest.

Guarantees:

 . Neither of us is, or will be in the future, a guarantor of the exchange
  notes.

 . Our future subsidiaries, other than foreign subsidiaries, will fully and
  unconditionally guarantee our senior credit facility and the exchange notes
  on a joint and several basis. See "Description of Exchange Notes--Note
  Guarantees." Their guarantee of the senior credit facility will be senior to
  the guarantee of the exchange notes.

The Exchange Offer:

 . The exchange offer will expire at 5:00 p.m., New York City time, on     ,
  1999, unless extended.

 . Upon our completion of the exchange offer, all old notes that are validly
  tendered and not withdrawn will be exchanged for an equal principal amount of
  exchange notes that are registered under the Securities Act.

 . Tenders of old notes may be withdrawn at any time prior to the expiration of
  the exchange offer.

 . The exchange of notes will not be a taxable exchange for U.S. federal income
  tax purposes.

 . We do not intend to list the exchange notes on any national securities
  exchange or Nasdaq.

 . We will not receive any cash proceeds from the exchange offer.

Notice to Investors:

 . You should consider carefully the risk factors beginning on page 7 of this
  prospectus before tendering your old notes in the exchange offer.

 . Neither the SEC nor any state securities commission has approved or
  disapproved of the exchange notes or determined if this prospectus is
  truthful or complete. Any representation to the contrary is a criminal
  offense.

                   The date of this prospectus is     , 1999.

Prospectus Summary.........................................................   1
Risk Factors...............................................................   7
  Old notes outstanding after the exchange offer will not have registration
   rights and we expect the market for the old notes to be illiquid........   7
  As a result of our significant debt, we may not be able to meet our
   obligations or obtain additional financing for capital expenditures or
   other beneficial activities on favorable terms..........................   7
  Your exchange notes will be subordinate to our senior debt and if we must
   repay our senior debt in the event of a default, we may not have enough
   assets left to pay you or the other noteholders.........................   8
  Our other indebtedness may limit or restrict our ability to incur
   additional debt, pay dividends and make distributions, transfer or sell
   assets, or merge or consolidate.........................................   9
  Our other indebtedness may prevent us from satisfying our obligations
   under the notes.........................................................   9
  We may not have sufficient funds to repay the exchange notes upon a
   change of control.......................................................   9
  If one of our owners exercises its put right, we would be required to
   borrow additional funds to purchase its membership interest; this would
   significantly increase our debt service obligations.....................  10
  We have only operated independently of Owens Corning since September 30,
   1998 and remain dependent upon Owens Corning to provide materials and
   services. Even though alternative sources exist for these materials and
   services, they may be more costly and could require us to change our
   manufacturing processes, which could be time-consuming and expensive....  10
  We may have conflicts of interest with our equityholders that could
   significantly increase our debt service obligations or result in reduced
   income from operations..................................................  11
  A downturn in the electronics industry and the movement of electronics
   industry production outside of North America has reduced demand for our
   products................................................................  11
  Our operating performance is dependent upon a limited number of
   customers. A decrease of business from major customers could result in
   reduced income from operations..........................................  12
  We depend on a stable supply of borates, which are one of the primary raw
   materials used in the production of glass yarns.........................  12
  If our customers switch to other suppliers of glass yarns, such as
   Vetrotex which intends to build a plant in Mexico, our income from
   operations would be reduced.............................................  13
  A disruption at one of our facilities would significantly decrease
   production, which could increase our cost of sales and reduce our income
   from operations.........................................................  13
  Since we sell a significant amount of our products outside the United
   States, exchange losses as a result of currency fluctuations could
   reduce our net income...................................................  14
  An easing of import restrictions and duties with respect to glass fabrics
   could reduce demand for our products, which would reduce our income from
   operations..............................................................  14
  The issuance of the old notes and any note guarantee may be subject to
   fraudulent conveyance laws..............................................  14
  We may suffer significant costs to make our systems year 2000 compliant
   which would result in reduced income from operations....................  15
  If we do not maintain good relations with our employees, we could face
   labor strikes or stoppages that would increase our cost of sales and
   decrease our income from operations.....................................  16
  If we become responsible for environmental and safety and health costs,
   we could suffer a decrease in net income................................  16
  Since an active trading market may not develop for the exchange notes,
   your ability to sell the exchange notes or the price at which you would
   be able to sell the exchange notes could be adversely affected..........  16

                               PROSPECTUS SUMMARY

  This summary highlights some information from this prospectus. It may not
contain all of the information that is important to you. To understand the
exchange offer fully, you should read this entire prospectus carefully,
including the risk factors and the financial statements.

                         Advanced Glassfiber Yarns LLC

  We are the second largest global supplier of glass yarns. Prior to and
including September 30, 1998, we were the glass yarns and specialty materials
business of Owens Corning. Since September 30, 1998, we have been a joint
venture between Porcher Industries and Owens Corning. Our principal executive
offices are located at 2556 Wagener Road, Aiken, South Carolina 29801, and our
telephone number is (803) 643-1377.


                               The Exchange Offer

  In this prospectus:

  . ""old notes" refer to the 9 7/8% Senior Subordinated Notes due 2009 that
    we issued on January 21, 1999;

  . ""exchange notes" refer to the 9 7/8% Series B Senior Subordinated Notes
    due 2009 that have been registered under the Securities Act of 1933 and
    that we are offering in exchange for the old notes; and

  . ""notes'' collectively refer to the old notes and the exchange notes.

The Exchange Offer......  We are offering to exchange $1,000 principal amount
                          of our exchange notes for each $1,000 principal
                          amount of old notes. As of the date of this
                          prospectus, $150,000,000 in aggregate principal
                          amount of old notes are outstanding.

                          We have registered the exchange notes under the
                          Securities Act and they are substantially identical
                          to the old notes, except for transfer restrictions,
                          registration rights and liquidated damages provisions
                          relating to the old notes.

Resale of the
Exchange Notes..........  Under existing SEC interpretations set forth in no-
                          action letters, we believe that the exchange notes
                          may be offered for resale, resold and otherwise
                          transferred by you without compliance with the
                          registration and prospectus delivery provisions of
                          the Securities Act so long as:

                           . you are acquiring the exchange notes in the
                             ordinary course of business;

                           . you are not participating, do not intend to
                             participate, and have no arrangement or
                             understanding with any person to participate, in
                             the distribution of the exchange notes issued to
                             you in the exchange offer; and

                           . you are not an affiliate of ours.

                                       1
<PAGE>


                          If our belief is inaccurate and you transfer any
                          exchange note without delivering a prospectus meeting
                          the requirements of the Securities Act or without an
                          exemption from registration of your exchange notes,
                          you may incur liability under the Securities Act. We
                          do not assume or indemnify you against this
                          liability.

                          Each participating broker-dealer that is issued
                          exchange notes for its own account in exchange for
                          old notes which were acquired as a result of market-
                          making or other trading activities, must acknowledge
                          that it will deliver a prospectus meeting the
                          requirements of the Securities Act if it resells any
                          exchange notes. The accompanying letter of
                          transmittal states that by so acknowledging and by
                          delivering a prospectus, a participating broker-
                          dealer will not be deemed to admit that it is an
                          "underwriter" within the meaning of the Securities
                          Act. A participating broker-dealer may use this
                          prospectus for an offer to resell, resale or other
                          retransfer of the exchange notes. We will make this
                          prospectus and any amendment or supplement to this
                          prospectus available for a period of 180 days after
                          the date of this prospectus to any participating
                          broker-dealer reselling any exchange notes. We
                          believe that no registered holder of the old notes is
                          an affiliate of ours as defined in Rule 405 of the
                          Securities Act.

                          All other broker-dealers may not rely on existing SEC
                          interpretations set forth in no-action letters and,
                          absent an exemption, must comply with the
                          registration and prospectus delivery requirements of
                          the Securities Act in order to resell the old notes
                          or the exchange notes. These requirements include
                          being named as a selling security holder in a
                          registration statement relating to resales. These
                          broker-dealers may not use the exchange offer
                          prospectus for any resales.

                          The exchange offer is not being made to, nor will we
                          accept surrenders for exchange from, holders of old
                          notes in any jurisdiction in which this exchange
                          offer or our acceptance would not be in compliance
                          with the securities or blue sky laws of that
                          jurisdiction.

Accrued Interest on the
 Exchange Notes and the
 Old Notes..............
                          Interest on the exchange notes will accrue from the
                          last interest payment date on which interest was paid
                          on the old notes, or, if no interest was paid on the
                          old notes, from January 21, 1999, the date of
                          issuance of the old notes. Holders whose old notes

Conditions to the
 Exchange Offer.........  We are not required to accept for exchange any old
                          notes, and we may terminate or amend the exchange
                          offer, if:

                           . we are faced with any legal action or proceeding
                             that might materially impair our ability to
                             proceed with the exchange offer or if any
                             material adverse development occurs in an
                             existing action or proceeding we are involved in;

                           . the exchange offer violates applicable law or any
                             applicable SEC interpretations; or

                          We may waive these conditions, but we currently
                          anticipate that each of the conditions will be
                          satisfied. We reserve the right to terminate or amend
                          the exchange offer at any time before the expiration
                          date if any of these conditions occur.

Procedures for
 Tendering Old Notes....  If you are a holder of old notes who wishes to accept
                          the exchange offer, you must:

                           . complete, sign and date the accompanying letter
                             of transmittal, or a facsimile of the letter of
                             transmittal, and mail or otherwise deliver the
                             letter of transmittal, together with your old
                             notes to the exchange agent at the address set
                             forth under "The Exchange Offer--Exchange Agent;"
                             or

                           . arrange for The Depository Trust Company to
                             transmit all required information, including an
                             agent's message forming part of a book-entry
                             transfer in which you agree to be bound by the
                             terms of the letter of transmittal, to the
                             exchange agent in connection with a book-entry
                             transfer.

                          By tendering your old notes in either manner, you
                          will be representing that:

                           . you are acquiring the exchange notes in the
                             ordinary course of business;

                                       3
<PAGE>

                           . you are not participating, do not intend to
                             participate, and have no arrangement or
                             understanding with any person to participate, in
                             the distribution of the exchange notes issued to
                             you in the exchange offer; and

                           . you are not an affiliate of ours.

Special Procedures for
 Beneficial Owners......  If you beneficially own old notes registered in the
                          name of a broker, dealer, commercial bank, trust
                          company or other nominee and you wish to tender your
                          old notes in the exchange offer, you should contact
                          the registered holder promptly and instruct it to
                          tender on your behalf. If you wish to tender on your
                          own behalf, you must, prior to completing and
                          executing the letter of transmittal and delivering
                          your old notes, either arrange to have your old notes
                          registered in your name or obtain a properly
                          completed bond power from the registered holder. The
                          transfer of registered ownership may take
                          considerable time.

Guaranteed Delivery
 Procedures.............  If you wish to tender your old notes and time will
                          not permit your required documents to reach the
                          exchange agent by the expiration date, or the
                          procedures for book-entry transfer cannot be
                          completed on time, you may tender your old notes
                          according to the guaranteed delivery procedures
                          described in "The Exchange Offer--Guaranteed Delivery
                          Procedures."

Use of Proceeds.........  We will not receive any proceeds from the exchange of
                          notes in the exchange offer. We will pay all our
                          expenses incurred in connection with the exchange
                          offer.

U.S. Federal Tax          The exchange of notes in the exchange offer will not
 Consequences...........  result in any gain or loss to you for U.S. federal
                          income tax purposes. See "United States Federal Tax
                          Considerations."

Effect on Holders of
 Old Notes..............  As a result of this exchange offer, we will have
                          fulfilled an obligation under the registration rights
                          agreement with the initial purchasers of the old
                          notes and, as a result, there will be no increase in
                          the interest rate on the old notes. If you do not
                          tender your old notes in the exchange offer:

                           . you will continue to hold the old notes and will
                             be entitled to all the rights and limitations
                             applicable to the old notes under the indenture
                             governing the notes, except for any rights under
                             the registration rights agreement that terminate
                             as a result of the completion of the exchange
                             offer; and


                                       4
<PAGE>

                           . you will not have any further registration or
                             exchange rights and your old notes will be
                             subject to restrictions on transfer. As a result,
                             the trading market for untendered old notes could
                             be adversely affected.

Shelf Registration
 Statement..............  In some situations, holders of old notes may require
                          us to file, and cause to become effective, a shelf
                          registration statement under the Securities Act,
                          which would cover resales of old notes by these
                          holders.


Exchange Agent..........  The Bank of New York is serving as the exchange agent
                          for the exchange offer.

                          The Exchange Notes

Issuers.................  The exchange notes will be the obligations of
                          Advanced Glassfiber Yarns and AGY Capital Corp. AGY
                          Capital is a wholly owned subsidiary of Advanced
                          Glassfiber Yarns.

Securities Offered......  Up to $150,000,000 in principal amount of 9 7/8%
                          Series B Senior Subordinated Notes due 2009.

Maturity Date...........  January 15, 2009.

Interest Payment
 Dates..................  January 15 and July 15, beginning on July 15, 1999.

Optional Redemption.....  We may redeem:

                           . all or part of the exchange notes beginning on
                             January 15, 2004, at the redemption prices
                             described in "Description of Exchange Notes--
                             Redemption;" and

                           . up to 35% of the exchange notes originally issued
                             at any time prior to January 15, 2002 at the
                             price of 110.125% of their face amount, plus
                             accrued and unpaid interest, with money we raise
                             in public equity offerings.


Ranking.................  The exchange notes are, and any note guarantees will
                          be, senior subordinated debt. They rank behind all of
                          our current and future indebtedness, other than trade
                          payables, except indebtedness that expressly provides
                          that it is not senior to the exchange notes. The
                          exchange notes will effectively rank behind any of
                          our future indebtedness that is secured by any of our
                          assets to the extent of the value of those assets,
                          even if the indebtedness expressly provides that it
                          is not senior to the exchange notes.

Note Guarantees.........  If we form or acquire any additional U.S.
                          subsidiaries, they will guarantee the exchange notes
                          on an unsecured basis. The note

<PAGE>

                          guarantees will be senior subordinated debts. They
                          will rank behind:

                           . all of the indebtedness of the note guarantors,
                             other than trade payables, except indebtedness
                             that expressly provides that it is not senior to
                             the note guarantees; and

                           . any indebtedness of the note guarantors that is
                             secured by any assets to the extent of the value
                             of such assets.

Mandatory Offer to
 Purchase...............  If we sell assets not in the ordinary course of
                          business or experience a change of control, we may be
                          required to offer to purchase the exchange notes at a
                          purchase price equal to 101% of their face amount,
                          plus interest, within 30 to 60 days after these
                          events. If we are required to offer to purchase the
                          exchange notes, we cannot assure you that we will
                          have adequate funds to do so at that time or that we
                          will be able to obtain funds from third party sources
                          on reasonable terms, if at all.

Basic Covenants
 of Indenture...........  We will issue the exchange notes under an indenture
                          that contains covenants for your benefit. These
                          covenants limit or restrict our ability and the
                          ability of our subsidiaries to:

                           . incur additional debt;

                           . pay dividends and make distributions;

                           . repurchase securities;

                           . make investments;

                           . create liens;

                           . transfer or sell assets;

                           . enter into transactions with affiliates;

                           . issue or sell stock of subsidiaries; or

                           . merge or consolidate.

                          However, these restrictions are subject to a number
                          of important qualifications and exceptions. For more
                          details, see "Description of Exchange Notes--Material
                          Covenants."

                                  Risk Factors

  You should read the "Risk Factors" section, beginning on page 7, as well as
the other cautionary statements throughout this prospectus, to ensure you
understand the risks associated with tendering your old notes in the exchange
offer.

                                       6

<PAGE>

                                  RISK FACTORS

  Before you tender your old notes, you should be aware that there are various
risks involved in this type of investment, including those we describe below.
You should consider carefully these risk factors together with all of the other
information included in this prospectus before you decide to tender your old
notes in the exchange offer.

Old notes outstanding after the exchange offer will not have registration
rights and we expect the market for the old notes to be illiquid.

  If you do not exchange your old notes for exchange notes pursuant to the
exchange offer, your old notes will continue to be subject to the restrictions
on transfer of the old notes. In general, you may not offer or sell old notes
unless they are registered under the Securities Act, except pursuant to an
exemption from the registration requirements of the Securities Act and
applicable state securities laws. We do not currently intend to register the
old notes under the Securities Act.

  Under existing SEC interpretations, we believe that you may offer for resale,
resell or otherwise transfer the exchange notes without compliance with the
registration and prospectus delivery requirements of the Securities Act, so
long as:

  .you are acquiring the exchange notes in the ordinary course of business;

  . you are not participating, do not intend to participate, and have no
    arrangement or understanding with anyone to participate, in the
    distribution of the exchange notes issued to you in the exchange offer;
    and

  .you are not an affiliate of ours.

  Each broker-dealer that receives exchange notes for its own account in
exchange for old notes, where the old notes were acquired by the broker-dealer
as a result of market-making activities or other trading activities, must
acknowledge that it will deliver a prospectus in connection with any resale of
exchange notes. See "Plan of Distribution." To the extent that old notes are
tendered and accepted in the exchange offer, the trading market for untendered
and tendered but unaccepted old notes will be adversely affected.

As a result of our significant debt, we may not be able to meet our obligations
or obtain additional financing for capital expenditures or other beneficial
activities on favorable terms.

  We incurred significant debt in connection with the financings described
under "The Formation Transactions" and, as a result, we have significant debt
service obligations. As of March 31, 1999, we had approximately $389.0 million
of indebtedness. We also had the ability to incur $66.6 million of additional
debt under our senior credit facility. See "Capitalization." As of March 31,
1999, the old notes were subordinated to $241.6 million of senior debt. In
addition, the indenture governing the notes does not fully prohibit us from
incurring substantial additional indebtedness. We can incur additional
indebtedness if our consolidated fixed charge coverage ratio is greater than
2.0 to 1.0. We may also incur up to $10.0 million of capitalized lease
obligations and purchase money indebtedness and up to $10.0 million of other
indebtedness regardless of our consolidated fixed charge ratio. If we add new
debt to our current debt levels, the related risks that we now face could
intensify. See "Capitalization," "Selected Historical Financial Information,"
"Description of Other Indebtedness" and "Description of Exchange Notes--
Material Covenants--Limitation on Incurrence of Additional Indebtedness."

                                       7

  Our substantial indebtedness poses important consequences to you, including
the risk that:

  . we will use a substantial portion of our cash flow from operations to pay
    principal and interest on our debt, thereby reducing the funds available,
    or limiting our ability to obtain additional financing on satisfactory
    terms, for working capital, capital expenditures, acquisitions, research
    and development and other general corporate purposes;


  . our level of indebtedness may make us more vulnerable to economic
    downturns and may limit our ability to withstand competitive pressures;

  . our debt may bear interest at variable rates which could create higher
    debt service requirements if market interest rates increase; and

  . our failure to comply with the financial and other covenants applicable
    to our debt could result in an event of default, which, if not cured or
    waived, could have a material adverse effect on us.

  If we successfully implement our business and operating strategies, we
believe we will have enough capital to carry on our business and service our
debt requirements for the foreseeable future. However, if we cannot generate
sufficient cash flow from operations to meet our obligations, we may be forced
to reduce or delay capital expenditures, sell assets, restructure or refinance
our debt, or seek additional equity capital. We cannot assure you that any of
these remedies would be satisfactory or could be effected on satisfactory
terms, if at all. Our ability to pay principal and interest on the exchange
notes and to satisfy our other debt obligations will depend on our future
operating performance. Our operating performance will be affected by prevailing
economic conditions and financial, business and other factors which may be
beyond our control. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources,"
"Description of Other Indebtedness" and "Description of Exchange Notes."

Your exchange notes will be subordinate to our senior debt and if we must repay
our senior debt in the event of a default, we may not have enough assets left
to pay you or the other noteholders.

  Before paying principal and interest on the exchange notes, we must first
make payments on any of our existing and future senior debt that is in default,
including all outstanding amounts under our senior credit facility. As of March
31, 1999, we had approximately $241.6 million of senior indebtedness. In
addition, we had approximately $66.6 million of additional borrowing
availability under our senior credit facility.

  Substantially all of our real and personal property that we use in our
business operations secures our obligations under our senior credit facility.
If we default on any payments required under any of our secured debt, the
secured lenders could declare all amounts outstanding, together with accrued
and unpaid interest, immediately due and payable. If we are unable to repay
amounts due, the lenders could proceed against the collateral securing the
debt. If the lenders proceed against any of the collateral, we may not have
enough assets left to pay you or other noteholders. Moreover, if we become
bankrupt or similarly reorganize, we may not be able to use our assets to pay
you or other noteholders until after we pay all of our senior debt, including
all indebtedness under the existing senior credit facility or any replacement
senior credit facility. In addition, the existing senior credit facility and
any replacement senior credit facility may prohibit us from paying amounts due
on the

                                       8
<PAGE>

exchange notes, or from purchasing, redeeming or otherwise acquiring the
exchange notes if a default exists under our senior debt. None of our non-
United States subsidiaries will guarantee the exchange notes and the exchange
notes will be effectively subordinated in right of payment to all debt and
other liabilities, including trade payables, of these subsidiaries. See
"Description of Exchange Notes--Subordination of the Exchange Notes and the
Note Guarantees."

Our indebtedness may limit or restrict our ability to incur additional debt,
pay dividends and make distributions, transfer or sell assets, or merge or
consolidate.

  Our senior credit facility and the indenture governing the notes each contain
a number of significant covenants. These covenants limit or restrict our
ability to:

  . incur additional debt;

  . pay dividends and make distributions;

  . repurchase securities;

  . make investments;

  . create liens;

  . transfer or sell assets;

  . enter into transactions with affiliates;

  . issue or sell stock of subsidiaries; or

  . merge or consolidate.

  These limitations are set forth in their entirety in article VI of the senior
credit facility credit agreement, beginning on page 76, and in section 5.9, on
page 73, and in article III of the indenture, beginning on page 39. Both of
these documents have been filed as exhibits to the registration statement of
which this prospectus is a part. These limitations and restrictions may
adversely affect our ability to finance our future operations or capital needs
or engage in other business activities that may be in our best interests.

Our other indebtedness may prevent us from satisfying our obligations under the
notes.

  Our senior credit facility also requires us to comply with financial ratios.
Our ability to comply with these ratios may be affected by events beyond our
control. If we breach any of the covenants in the senior credit facility or the
indenture, or if we are unable to comply with the required financial ratios, we
may be in default under the senior credit facility and the indenture. If we
default under the senior credit facility, the lenders can declare all
borrowings outstanding, including accrued interest and other fees, due and
payable. If we use all of our available cash to repay borrowings under the
senior credit facility, we may not be able to make payments on the exchange
notes. See "Description of Other Indebtedness" and "Description of Exchange
Notes."

We may not have sufficient funds to repay the exchange notes upon a change of
control.

  If we experience a change of control, you may have the right to require us to
purchase your exchange notes at a purchase price equal to 101% of the principal
amount of your exchange notes plus accrued and unpaid interest. In these
circumstances, we may also be required to:

                                       9
<PAGE>

  . repay our outstanding senior debt; or

  . obtain our lenders' consent to our purchase of the exchange notes.

  If we cannot repay our debt or cannot obtain the needed consents, we may be
unable to purchase the exchange notes. This would be an event of default under
the indenture. Upon a change of control, we cannot guarantee that we will have
sufficient funds to make any debt payment as described above. To avoid default,
we would try to refinance our debt. We cannot guarantee, however, that any
refinancing, if available, would be on favorable terms. See "Description of
Exchange Notes--Change of Control."

  The events that qualify as a change of control under the indenture may also
be events of default under the senior credit facility or other indebtedness. An
event of default under the senior credit facility would permit our lenders to
accelerate our indebtedness. If we cannot repay these borrowings when due, the
lenders could proceed against the collateral securing the debt.

If one of our owners exercises its put right, we would be required to borrow
additional funds to purchase its membership interest; this would significantly
increase our debt service obligations.

  Our affairs and the relationship between Owens Corning and Porcher
Industries, our owners, are governed by an operating agreement. Under this
operating agreement, Owens Corning and Porcher Industries each have the right
to "put" their respective ownership interests to us at any time beginning on
September 30, 2003. Funding the put rights would require us to borrow funds.
The operating agreement and the indenture impose financial tests and
restrictions on our ability to borrow to fund the put rights. If we satisfy
those financial tests, we would be obligated to purchase the ownership interest
that has been tendered. Even if we satisfy the financial tests, funding a put
right could significantly increase our debt service obligations. As of March
31, 1999, we could not finance the purchase of all or any portion of either
member's ownership interest and maintain a credit rating of at least B on our
existing unsecured debt. See "Operating Agreement."

We have only operated independently of Owens Corning since September 30, 1998
and remain dependent upon Owens Corning to provide materials and services. Even
though alternative sources exist for these materials and services, they may be
more costly and could require us to change our manufacturing processes, which
could be time-consuming and expensive.

  Prior to September 30, 1998, we operated as a business unit of Owens Corning
and, therefore, we have a limited independent financial or operating history.
We have historically been dependent upon Owens Corning to provide us with raw
materials and capital equipment, in addition to various services, including
research and development, legal, accounting, financial, data processing,
auditing, treasury, cash management, human resource and administrative
services. In connection with the formation transactions, we entered into supply
agreements with Owens Corning under which Owens Corning continues to provide
raw materials, capital equipment and various services to us for limited periods
of time. During the terms of these agreements, our operating success and
viability are dependent in part upon the performance by Owens Corning of its
obligations under the agreements. We do not expect to extend these agreements.
Prior to their expiration, we will need to arrange for sources of raw materials
and other equipment and establish independent operational, management,
financial and information systems and controls. We cannot assure you that we
will be able to

                                       10
<PAGE>

successfully transition these services or operate our business independently of
Owens Corning. See "Related Party Transactions."

  In addition, some of the capital equipment used in the production process of
glass yarns are not widely manufactured, particularly bushings. Bushings are
heat-resistant platinum and rhodium trays through which molten glass is passed
to form glass filaments. Our bushings are currently manufactured and
periodically reconditioned by Owens Corning. Owens Corning has agreed to
continue to provide bushings and reconditioning services to us for seven years.
See "Related Party Transactions." Only a limited number of companies are
qualified to manufacture and recondition bushings. We would incur significant
costs and a transition period of several months if we switched to another
supplier of bushings. In addition, platinum and rhodium, which are the primary
elements used in the manufacturing and reconditioning of bushings, are subject
to shortages in supply. Any failure of Owens Corning to provide us bushings or
reconditioning services for the bushings or a supply shortage of platinum or
rhodium could increase our cost of sales and reduce our income from operations.

  Alternative sources exist for the raw materials, services and equipment that
Owens Corning provides to us. However, we believe these sources are more costly
and could require us to change our manufacturing processes. Since this could be
time-consuming and expensive, our income from operations could be reduced if
Owens Corning stops providing us with these materials and services.

We may have conflicts of interest with our equityholders that could
significantly increase our debt service obligations or result in reduced income
from operations.

  Porcher Industries, through wholly owned subsidiaries, owns a 51% ownership
interest in Advanced Glassfiber Yarns. A wholly owned subsidiary of Owens
Corning owns the remaining 49% ownership interest. As a result of its
controlling interest, Porcher Industries elects a majority of our directors and
appoints new management. Consequently, Porcher Industries has the ability to
control our policies and operations. Circumstances may occur in which the
interests of Porcher Industries and Owens Corning, as our principal
equityholders, could conflict with your interests as debtholders. See "--If one
of our owners exercises its put right, we would be required to borrow
additional funds to purchase its membership interest; this would significantly
increase our debt service obligations," "Management--Executive Officers,
Directors and Other Key Employees," "Security Ownership" and "Related Party
Transactions."

  Porcher Industries, including its affiliates, such as BGF Industries, is also
our largest customer. Although we believe that Porcher Industries intends to
operate us independently from its other operations, this relationship may give
rise to potential conflicts of interest. The potential conflicts could include
the perception by our other customers that we may provide favorable pricing
terms or disclose confidential customer information to Porcher Industries,
which could adversely affect our relationships with our other customers. If
these potential conflicts of interest adversely affect these relationships, any
resulting loss of business could result in reduced income from operations.

A downturn in the electronics industry and the movement of electronics industry
production outside of North America has reduced demand for our products.

  We sell our products for use in a wide range of applications in the
electronic, industrial and construction markets. The electronics industry
represents the glass yarn industry's largest market.

                                       11
<PAGE>

Any downturn in the electronics industry, which is susceptible to cyclical and
general economic downturns, would reduce demand for glass yarns industry-wide.
A reduction in overall demand would likely result in increased competition
between us and other producers of glass yarns for customers in other end-use
markets and may cause us to reduce the price of our products which would
adversely affect our profitability.

  Primarily as a result of economic turmoil in Asia, demand for electronic
products began to decrease in late 1997 and early 1998. We began to experience
decreased demand for fine yarns in the second quarter of 1998 as both weavers
and laminators reduced their inventory to match reduced demand for electronic
products. This trend continued through the end of 1998. If the demand for fine
yarns does not stabilize or improve, our sales and profitability could be
adversely affected.

  In addition, due to the recent economic turmoil in Asia and the resulting
fall in currency exchange rates, imports of goods such as rigid laminates and
printed circuit boards from Asia have increased. This has negatively affected
demand for heavyweight glass fiber fabrics used in the manufacture of
electronic products and produced domestically by many of our customers. The
result was a decrease in demand for our heavy yarns in North America. To the
extent the increased competition from Asian laminators and printed circuit
board manufacturers continues to negatively affect demand for glass fiber
fabrics in North America, our sales and profitability could be adversely
affected.

Our operating performance is dependent upon a limited number of customers. A
decrease of business from major customers could result in reduced income from
operations.

  We depend upon a limited number of large customers for a majority of our
sales. Sales to our top ten customers accounted for approximately 67% of our
net sales in 1998 and approximately 67% of our net sales in the first quarter
of 1999. Sales to our largest customer, Porcher Industries, including its
affiliates, such as BGF Industries, accounted for approximately 20% of our net
sales in 1998 and approximately 24% of our net sales in the first quarter of
1999. A decrease in business from, or the loss of, any of our major customers
could result in reduced income from operations.

  In addition, our operating performance will depend to a significant extent
upon the commercial success of our major customers and their continued
willingness to purchase our products. Any significant downturn in the business
of our major customers could cause them to reduce or discontinue their
purchases from us. This could result in reduced income from operations. See "--
A downturn in the electronics industry and the movement of electronics industry
production outside of North America has reduced demand for our products," "--We
may have conflicts of interest with our equityholders that could significantly
increase our debt service obligations or result in reduced income from
operations." and "Business--Marketing and Sales."

We depend on a stable supply of borates, which are one of the primary raw
materials used in the production of glass yarns.

  We use specific borates in the production processes at our Aiken facility,
which are sourced from a supplier in Turkey that is owned by the Turkish
government. This supply of borates could be interrupted for a number of
reasons, including political instability in Turkey. Our supply of borates from
Turkey is sourced through Owens Corning under a supply agreement which provides
that, if there is a limited or reduced supply of borates, Owens Corning will
allocate a portion of such supply

                                       12
<PAGE>


to us. The proprietary nature of the identity of the specific borates used in
our manufacturing processes is a key factor in differentiating our products
from the products of our competitors. Any failure of Owens Corning to perform
under the supply agreement or any dispute relating to the allocation of a
limited borates supply could interrupt our supply of these borates and
adversely affect our ability to manufacture glass yarns. Boric acid is
considered by some to be a cost-effective substitute for borates. While we
believe that we could switch to boric acid, which is more readily available
than borates, the process for switching would be time-consuming and expensive.
This would initially result in significant quality issues and could in the
longer term cause us to lose business because of a decline in product quality,
one of our most important competitive advantages.

If our customers switch to other suppliers of glass yarns, such as Vetrotex
which intends to build a plant in Mexico, our income from operations would be
reduced.

  Our industry is highly competitive. We believe that the principal competitive
factors affecting the glass yarns industry include:

  . quality, performance, pricing and consistency of products;

  . responsiveness to customer requirements; and

  . ability to maintain stable customer relationships.

  Our primary competitors are PPG Industries Inc., with operations in the
United States, Vetrotex, a division of Compagnie de Saint Gobain, with
operations in France, Nitto Boseki Co., with operations in Japan, and Nippon
Electric Glass Co., Ltd., with operations in Japan. Some of our competitors may
have greater financial and other resources than we do. We cannot assure you
that we will be able to continue to compete effectively in the future or that
other competitors will not enter the glass yarns industry.

  We and PPG are the only major producers of glass yarns with production
facilities in North America. The establishment by one of our competitors of
production facilities in North America or the increase in production capacity
in North America by PPG could materially adversely affect our North American
market share. In this regard, Vetrotex has announced that it intends to build a
plant in Mexico for the production of glass yarns, primarily for use in the
electronics market. Vetrotex has publicly stated that it expects this new plant
to begin operations in the second half of 1999.

A disruption at one of our facilities would significantly decrease production,
which could increase our cost of sales and reduce our income from operations.

  A significant portion of our net sales are currently derived from our
production facilities located in Aiken, South Carolina and Huntingdon,
Pennsylvania. The Aiken plant accounted for 60% of our total net sales in 1998
and 60% of our total net sales in the first quarter of 1999. The Huntingdon
plant accounted for 29% of our total net sales in 1998 and 31% of our total net
sales in the first quarter of 1999. Approximately 11% of our total net sales in
1998 and 9% of our total net sales in the first quarter of 1999 were sourced
from Owens Corning's Battice, Belgium and Guelph, Canada facilities. We opened
a co-location facility with BGF Industries in South Hill, Virginia in June
1998, which became fully operational in the first quarter of 1999. The South
Hill plant accounted for .04% of our total net sales in 1998 and .2% of our
total net sales in the first quarter of 1999.

  Our facilities are designed to produce specific products. Consequently, some
products produced at one facility may not be produced at another facility. A
temporary or extended interruption in operations at any one of our facilities,
for any reason, including from labor strikes or a natural disaster, whether or
not covered by insurance, could increase our cost of sales and reduce our
income

                                       13
<PAGE>

from operations. See "Business--Manufacturing Facilities," "Business--
Employees" and "Related Party Transactions."

Since we sell a significant amount of our products outside the United States,
exchange losses as a result of currency fluctuations could reduce our net
income.

  In 1998, we derived approximately 32.3% of our net sales from products sold
outside the United States. We derived approximately 32.1% of our net sales in
the first quarter of 1999 from products sold outside the United States. The
United States dollar value of these 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. Although we do
not currently have a formal policy regarding hedging our currency risks, we
continually evaluate the necessity for entering into currency hedging
agreements to protect us from such risks. However, any such hedging agreements
may not be sufficient to eliminate risks relating to currency fluctuation.

  In addition, on January 1, 1999, eleven of the fifteen member countries of
the European Union adopted the Euro as their common legal currency and
established fixed conversion rates between their existing sovereign currencies
and the Euro. We cannot assure you that this conversion will not result in
decreased net income. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

An easing of import restrictions and duties with respect to glass fabrics could
reduce demand for our products, which would reduce our income from operations.

  Currently, the importation of glass yarns into the United States is not
subject to import regulations. However, the importation of glass fabrics
containing glass yarn is subject to import quotas, restrictions, duties and
tariffs. To the extent that these import regulations protect domestic producers
of glass fabrics, who are our primary customers, reductions in the level of
restrictions could adversely affect these customers and, consequently, result
in reduced income from operations.

The issuance of the old notes and any note guarantee may be subject to
fraudulent conveyance laws.

  Under applicable provisions of the U.S. Bankruptcy Code or comparable
provisions of state fraudulent transfer or conveyance laws, if we, at the time
we issued the old notes:

    (1) incurred such indebtedness with the intent to hinder, delay or
  defraud creditors; or

    (2) received less than reasonably equivalent value or fair consideration
  for incurring the indebtedness, and

    . were insolvent at the time of incurrence;

    . were rendered insolvent by reason of the incurrence, and the
      application of the proceeds thereof;

    . were engaged or were about to engage in a business or transaction for
      which our remaining assets constituted unreasonably small capital to
      carry on our businesses; or

    . intended to incur, or believed that we would incur, debts beyond our
      ability to pay as they matured,


                                       14
<PAGE>

then a court of competent jurisdiction could:
  . void, in whole or in part, the notes, and direct the repayment of any
    amounts paid thereunder to our creditors;
  . subordinate the notes to our obligations to our existing and future
    creditors; or
  . take other actions detrimental to the holders of the notes.

The measure of insolvency for purposes of the foregoing will vary depending
upon the law applied. Generally, however, we would be considered insolvent if
the sum of our debts, including contingent liabilities, was greater than all of
our assets at fair valuation or if the present fair saleable value of our
assets was less than the amount that would be required to pay the probable
liability on our existing debts, including contingent liabilities, as they
become absolute and matured. A note guarantee, at the time it is issued by one
of our subsidiaries, would be subject to the same fraudulent transfer or
conveyance laws as the notes.

We may suffer significant costs to make our systems year 2000 compliant which
would result in reduced income from operations.

  The term year 2000 issue is a general term used to describe the various
problems that may result from the improper processing of dates and date-
sensitive calculations by computers and process control equipment as the year
2000 is approached and reached. These problems generally arise from the fact
that most of the world's computer hardware and software have historically used
only two digits to identify the year in a date, often meaning that the computer
will fail to distinguish dates in the "2000s" from dates in the "1900s." These
problems may also arise from other sources as well, such as the use of special
codes and conventions in software that make use of the date field.

  We have identified several key information technology and non-information
technology systems that need to be replaced in order to become year 2000
compliant. The information technology systems to be replaced include all
financial and order entry/planning systems and non-information technology
systems to be replaced include some process control systems. In addition to
internal systems, we are dependent on external suppliers for the delivery of
raw materials, energy and supplies. Two-thirds of our top external suppliers,
who represent approximately 90% of our total purchases, have informed us that
they are or expect to be year 2000 compliant. 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 incur higher cost of sales which would
result in reduced income from operations. Likewise, failure of key suppliers or
customers to achieve compliance could adversely impact our ability to
manufacture, distribute and sell products.

  The estimated cost of our year 2000 compliance program is $2.8 million and we
are not aware of any other material operational issues or other costs
associated with preparing our systems for the year 2000. We cannot assure you
that there will not be a delay in, or increased costs associated with, the
implementation, remediation and replacement of the necessary systems to address
the year 2000 issue. If we are unable to adequately address the year 2000 in a
timely manner, our ability to properly manufacture our products and conduct
normal business operations would be impacted resulting in increased costs and
decreased revenue.


                                       15
<PAGE>

If we do not maintain good relations with our employees, we could face labor
strikes or stoppages that would increase our cost of sales and decrease our
income from operations.

  Labor unions represent employees at both the Aiken facility and the
Huntingdon facility. The collective bargaining agreement covering workers at
the Aiken facility expires on June 30, 1999 and the agreement covering workers
at the Huntingdon facility expires on October 31, 1999. We cannot assure you
that we will be able to maintain good relationships with these labor unions or
that we will be able to successfully negotiate new collective bargaining
agreements on satisfactory terms in the future. If we fail to maintain good
relationships with the labor unions or fail to negotiate satisfactory
collective bargaining agreements, we could face labor strikes or stoppages that
would result in increased cost of sales and decreased income from operations.
See "Business--Employees."

If we become responsible for environmental and safety and health costs, we
could suffer a decrease in net income.

  Various federal, state and local environmental laws and requirements govern
the use of our facilities. These laws and requirements govern:

  . discharges to air and water;

  . the handling and disposal of solid and hazardous substances and wastes;
    and

  . the clean-up of contamination from releases of hazardous substances at
    our facilities and off-site disposal locations.

Laws and requirements relating to workplace safety and worker health also
govern our operations. These laws and requirements establish formaldehyde,
asbestos and noise standards and regulate the use of hazardous chemicals in the
workplace. We have taken, and will continue to take, steps to comply with these
laws and requirements. We believe, based upon currently available information,
that complying with environmental and health and safety laws and requirements
will not require material capital expenditures in the foreseeable future.
However, we cannot assure you that complying with the foregoing environmental
or health and safety laws and requirements will not result in a decrease in net
income. Moreover, we cannot assure you that future laws, ordinances or
regulations will not give rise to additional compliance or remediation costs
which could result in a decrease in net income.

Since an active trading market may not develop for the exchange notes, your
ability to sell the exchange notes or the price at which you would be able to
sell the exchange notes could be adversely affected.

  The old notes were offered to a small number of institutional buyers and are
eligible for trading in the PORTAL Market. The exchange notes will be a new
issue of securities for which there is no existing trading market. We cannot
assure you as to the liquidity of markets that may develop for the exchange
notes, your ability to sell the exchange notes or the price at which you would
be able to sell the exchange notes. If these markets were to exist, the
exchange notes could trade at prices that may be lower than their principal
amount or purchase price depending on many factors, including prevailing
interest rates and the markets for similar securities. First Union Capital
Markets and Warburg Dillon Read LLC have advised us that they currently intend
to make a market with respect to the exchange notes. However, they are not
obligated to do so, and any market making with respect to the exchange notes
may be discontinued at any time without notice. In addition, this market

                                       16
<PAGE>

making activity may be limited during the pendency of the exchange offer or the
effectiveness of a shelf registration statement. We do not intend to apply for
listing of the exchange notes on any national securities exchange or on Nasdaq.
The liquidity of, and trading market for, the exchange notes also may be
adversely affected by changes in the market for high yield securities and by
changes in our financial performance or prospects or in the prospects for
companies in our industry generally. As a result, you cannot be sure that an
active trading market will develop for the exchange notes.

           CAUTIONARY STATEMENT REGARDING FORWARD LOOKING STATEMENTS

  Some of the information in this prospectus may contain forward looking
statements. These statements include, in particular, statements about our
plans, strategies and prospects under the headings "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business." 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 these forward looking
statements are reasonable, we cannot assure you that our plans, intentions or
expectations will be achieved. Important factors that could cause our actual
results to differ materially from the forward looking statements we make in
this prospectus are set forth in the "Risk Factors" section and elsewhere in
this prospectus. All forward looking statements attributable to us or persons
acting for us are expressly qualified in their entirety by our cautionary
statements.

                            MARKET AND INDUSTRY DATA

  Unless we indicate otherwise, we derived the glass yarns industry data, our
market share and the percentage of our sales attributable to various end-use
markets in this prospectus from our internal surveys and estimates. We believe
that there are no industry-wide publications or trade associations that report
industry, market and end-use data. No independent sources have verified our
internal surveys or estimates. While this data is shown with numerical
specificity, these estimates are based on sources that are not complete and on
collection methodologies that are not systematic, including:

  . routine discussions with customers to estimate existing and projected
    global glass yarn sales;

  . negotiations with customers in which pricing information was discussed;

  . development of a business model with independent consultants to estimate
    glass yarns consumption in the electronics industry;

  . our understanding, based on ordinary course discussions with our
    customers, of the end-use markets served directly and indirectly by our
    customers, which we have used to estimate the percentage of our glass
    yarn sales to the electronics, industrial, construction and specialty
    markets;

  . review of fabric production quantities with major weavers; and

  . public statements by competitors, independent financial analysts and a
    regional trade association.

  These estimates represent our management's good faith assessments and are
believed to be based on methodologies similar to those used by our major
competitors, but nevertheless are inherently subject to inaccuracy.

                                       17

  In this prospectus, we express our capacity utilization as a percentage of
installed bushings in use. Bushings are heat-resistant platinum and rhodium
trays through which molten glass is passed to form glass filaments. The fact
that a bushing is in use does not necessarily indicate that we are obtaining
the highest volumes or margins possible with that bushing. Volume and margin
depend on numerous factors including the production process in use and the
product mix.

                           THE FORMATION TRANSACTIONS

  Porcher Industries and Owens Corning beneficially own 51% and 49% interests
in Advanced Glassfiber Yarns, respectively. On July 1, 1998, Owens Corning
formed Advanced Glassfiber Yarns to own and operate Owens Corning's glass fiber
yarns and specialty materials business. On September 30, 1998, Owens Corning
sold a 51% interest in Advanced Glassfiber Yarns to our largest customer,
Porcher Industries. The total consideration paid by Porcher Industries was
approximately $338.9 million, excluding $3.2 million of transaction fees.
Porcher Industries is a leading global manufacturer of industrial fabrics and
operates in North America primarily through its wholly owned subsidiary, BGF
Industries. In connection with Porcher Industries' majority purchase, Owens
Corning entered into a number of agreements to provide various raw materials,
capital equipment and services to us.

  Concurrently with Porcher Industries' majority purchase, we recapitalized
Advanced Glassfiber Yarns by borrowing a total of $404.0 million through a
combination of $254.0 million under a senior credit facility and $150.0 million
under a senior subordinated credit facility. We used the proceeds of these
borrowings plus a $2.2 million contribution from Owens Corning to pay:

  . an aggregate cash distribution of $399.2 million, including cash
    distributions of $203.6 million to Porcher Industries and $195.6 million
    to Owens Corning; and

  . approximately $7.0 million in transaction fees and expenses.

  In connection with the above-described "formation transactions," Porcher
Industries' net cash outlay was $138.5 million, represented by the $338.9
million paid for the 51% interest in Advanced Glassfiber Yarns, plus $3.2
million in fees paid in connection with the majority purchase, less the $203.6
million cash distribution Porcher Industries received from us. Owens Corning
received $532.3 million in total consideration, comprised of the $338.9 million
paid to it by Porcher Industries and the $195.6 million cash distribution Owens
Corning received from us less a $2.2 million contribution.

  The net proceeds from the offering of the old notes, together with additional
borrowings under our senior credit facility, were used to repay all amounts
outstanding under our senior subordinated credit facility incurred in
connection with the formation transactions.

                                USE OF PROCEEDS

  We will not receive any cash proceeds from the exchange of old notes pursuant
to the exchange offer. Our net proceeds from the sale of the old 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 $315.0 million senior credit
facility, to repay all debt outstanding under our $150.0 million senior
subordinated credit facility, which was incurred in connection with the
formation transactions. For a description of the senior credit facility, see
"Description of Other Indebtedness--Senior Credit Facility."

                                 CAPITALIZATION

  The following table sets forth our capitalization as of March 31, 1999 and as
adjusted to give effect to the exchange of old notes for exchange notes as if
the exchange offer had occurred on March 31, 1999. As of March 31, 1999, we had
approximately $66.6 million of borrowing availability under our senior credit
facility.

  The following table should be read in conjunction with our historical
financial statements, the unaudited pro forma condensed financial information,
the related notes and the other information contained elsewhere in this
prospectus. See "Where You Can Find More Information," "Unaudited Condensed Pro
Forma Financial Information," "Selected Financial Information" and

              UNAUDITED CONDENSED PRO FORMA FINANCIAL INFORMATION

  The following unaudited condensed pro forma statement of operations is based
upon our historical financial statements. The unaudited pro forma adjustments
are based upon available information and assumptions that we believe are
reasonable. The unaudited pro forma condensed statement of operations for the
year ended December 31, 1998 gives effect to the formation transactions and the
offering of the old notes as if they had occurred on January 1, 1998.

  The unaudited pro forma condensed statement of operations does not purport to
be indicative of what our results of operations would actually have been had
the formation transactions and the offering of the old notes been completed on
such dates, or to project our results of operations for any future period. The
pro forma financial information and the notes thereto should be read in
conjunction with our historical financial statements and the other financial
information included elsewhere in this prospectus.

  The accompanying pro forma condensed statement of operations does not include
a provision for income taxes because Advanced Glassfiber Yarns is a limited
liability company and is therefore not subject to income tax.

  The acquisition of the 51% interest in Advanced Glassfiber Yarns by Porcher
Industries was accounted for as a partial purchase business combination in
accordance with the provisions of APB No. 16 "Business Combinations" and EITF
Issue No. 88-16, "Basis in Leveraged Buyout Transactions" and is reflected as
such in the historical December 31, 1998 financial statements.

  (a) Owens Corning has historically provided glass marbles to us at cost.
      Pursuant to an agreement with Owens Corning, prices are set to earn a
      pre-determined margin for Owens Corning.
  (b) Owens Corning buys borates from a third party and has historically
      supplied borates to us at cost. Pursuant to an agreement with Owens
      Corning, prices are set at cost plus transport, process and terminal
      fees plus an annual administrative charge of $150,000.
  (c) Owens Corning has historically provided alloy and bushing fabrication
      services to us at cost. Pursuant to an agreement with Owens Corning,
      these services are provided to us at contractually agreed upon prices.
  (d) Owens Corning's Battice, Belgium manufacturing facility produces glass
      yarn products for our customers. We have entered into an agreement with
      Owens Corning to purchase glass yarns from the Battice facility at
      prices equal to our net sales prices less a fixed margin.
  (e) We have historically charged Owens Corning the actual manufacturing
      cost of sliver. Pursuant to an agreement with Owens Corning, we supply
      byproducts of our manufacturing processes known as "sliver" to Owens
      Corning at market prices.
  (f) Owens Corning produces Low Tex Type 30 for our customers. We have
      entered into an agreement with Owens Corning to receive a fee of 10% of
      the sales price from Owens Corning for sales of these products to our
      customers.
  (g) Owens Corning has historically provided sewage, wastewater treatment,
      stormwater and landfill services to the Aiken facility. No financial
      impact has been included in the pro forma statement of operations
      because Owens Corning has agreed to provide these services to us on
      substantially the same economic terms as provided historically.

  (2) Reflects the excess of the net pension expense and net post retirement
expense over the amounts recorded historically.

  (3) Reflects the interest expense and amortization of the deferred financing
costs associated with the borrowings under the senior credit facility and the
senior subordinated credit facility and the application of the net proceeds
therefrom (the "Financings") and the old notes, as if the Financings and the
offering of the old notes had been consummated as of January 1, 1998.

  (4) Reflects amortization of the intangible assets arising from the
acquisition by Porcher Industries of a 51% interest in Advanced Glassfiber
Yarns, based upon a useful life of 5-25 years.

  (5) Reflects additional depreciation arising from the partial step-up in
basis of plant and equipment to its estimated fair value.

                         SELECTED FINANCIAL INFORMATION

  We present below our selected historical and pro forma information. Selected
historical financial information related to Owens Corning's glass yarns and
specialty materials business is presented for each of the four years in the
period ended December 31, 1997 and the nine months ended September 30, 1998.
Selected historical financial information subsequent to consummation of the
formation transactions on September 30, 1998 is presented for the three months
ended December 31, 1998 and the three months ended March 31, 1999.

  We derived the historical information for each of the years in the two year
period ended December 31, 1997, the nine months ended September 30, 1998 and
the three months ended December 31, 1998 from our audited financial statements
which appear elsewhere in this prospectus. We derived the historical
information for the year ended December 31, 1995 from our audited financial
statements which are not included in this prospectus. We derived the historical
information for the year ended December 31, 1994 from unaudited financial
statements that we prepared.

  The following selected financial data at the end of and for the three month
periods ended March 31, 1998 and 1999 have been derived from unaudited
consolidated financial statements and, in our opinion, include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation, in all material respects, of our results of operations and
financial position at the end of and for each of the interim periods presented.
Interim period results are not necessarily indicative of results to be expected
for a complete fiscal year. The following selected historical financial
information for the three month periods ended March 31, 1998 and 1999 is
contained elsewhere in the prospectus.

  The historical financial statements of the business were derived from the
historical financial statements of Owens Corning. We have not adjusted our
historical statements of operations to reflect the effect of supply agreements
that we entered into with Owens Corning in connection with the formation
transactions.

  Our selected unaudited pro forma financial information is based upon the
historical financial statements of the business for the nine months ended
September 30, 1998 and the results of our operations for the period from
October 1, 1998 to December 31, 1998. The selected unaudited pro forma
information gives effect to the formation transactions and the offering and
exchange of the old notes as if they had occurred on January 1, 1998. The
selected unaudited pro forma financial information does not include a provision
for income taxes because Advanced Glassfiber Yarns is a limited liability
company and is therefore not subject to income tax. The selected unaudited pro
forma financial information does not purport to be indicative of what our
results of operations would actually have been had the formation transactions
and the offering of the old notes been completed on January 1, 1998, or to
project our results of operations for any future period.

  The unaudited as adjusted financial information for the three months ended
March 31, 1999 gives effect to the issuance of the old notes and the exchange
of the old notes for exchange notes as if these events occurred on January 1,
1999.

  We have presented adjusted EBITDA in our selected historical and pro forma
other data because it is a widely accepted financial indicator of a company's
ability to service indebtedness. You should not consider adjusted EBITDA as an
alternative to net income or loss, as a measure of operating

                                       23
<PAGE>

results, or to cash flows as a measure of liquidity in accordance with
generally accepted accounting principles. Adjusted EBITDA presented below may
not necessarily be comparable to similarly titled measures reported by other
companies as they are not calculated identically by all companies. We define
adjusted EBITDA as income or loss before income taxes and extraordinary item,
interest expense, depreciation and amortization expense, non-recurring charges
of $2.3 million in 1998 and $.3 million for the three months ended March 31,
1999, restructuring charges of $2.0 million in 1998 and the cumulative effect
of an accounting change.

  We have also presented the ratio of earnings to fixed charges. In calculating
the ratio of earnings to fixed charges, earnings consists of income or loss
before income taxes plus fixed charges. Fixed charges consist of interest
expense, whether expensed or capitalized, and the portion of rental expense
estimated to attributable to interest.

  You should read the unaudited historical and unaudited pro forma information
and the accompanying notes in conjunction with our historical financial
statements and financial information included elsewhere in this prospectus.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Introduction

  Advanced Glassfiber Yarns is a Delaware limited liability company formed by
Owens Corning to own and operate its glass yarns and specialty materials
business. On July 1, 1998, Owens Corning contributed substantially all of the
assets and liabilities of this business to us. 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.

  Before September 30, 1998, we were the glass yarns and specialty materials
business of Owens Corning. Accordingly, the historical financial information
for the year ended December 31, 1998 is based upon the historical financial
information of the business as it was operated by Owens Corning from January 1,
1998 through September 30, 1998 and the historical financial information of
Advanced Glassfiber Yarns from October 1, 1998 through December 31, 1998. The
historical financial statements contained in this prospectus for all periods
ending on or before September 30, 1998 have not been adjusted to reflect that
Owens Corning did not contribute all of the assets and liabilities of the
business to us. In addition, these historical financial statements have not
been adjusted to reflect the effect of the supply agreements entered into with
Owens Corning in connection with the formation transactions. See "Related Party
Transactions." The supply agreements generally require Owens Corning to provide
raw materials, capital equipment and services to us at Owens Corning's cost
plus pre-determined margins. For a presentation of the adjustments to our
historical financial statements to reflect the foregoing transactions, see
"Unaudited Condensed Pro Forma Financial Information" and the accompanying
notes.

  Net Sales. We recognize sales upon the shipment of products. Net sales
consist of sales to customers, including discounts and negotiated rebates.
Prices for our products depend upon the terms of our customer agreements and
the category of product being sold. During the first quarter of 1999, prices
for heavy yarns, excluding specialty materials, ranged from approximately $2.00
to $4.00 per kilogram and prices for fine yarns ranged from $4.00 to $12.00 per
kilogram. During the first quarter of 1999, prices for specialty materials
ranged from $12.00 to $29.00 per kilogram. Our net sales decreased from $275.0
million for 1996 to $268.6 million for 1998. Our net sales decreased from $72.9
million for the first quarter of 1998 to $62.0 million for the first quarter of
1999. These decreases in net sales were primarily due to a decreased demand for
heavy yarns used in rigid printed circuit boards which began in the fourth
quarter of 1997 and the effects of a strong U.S. dollar on sales in Europe.

  In late 1997 and early 1998, the demand for electronic products began to
decrease primarily as a result of economic turmoil in Asia. However, we only
began to experience a decline in demand for both fine yarns and heavy yarns in
the second quarter of 1998. Generally, the effect of a change in demand for
electronic products on our net sales lags behind the change by several months.
The demand for fine yarns for electronic applications also declined as both
weavers and laminators corrected their inventory to better match the reduced
demand for electronic products. This correction continued through 1998. The
volume of fine yarn sales has recently stabilized and is improving modestly in
1999. The demand for heavy yarns in North America for electronic applications
declined due to decreased demand for electronic products which caused a global
decline in demand for rigid laminates and printed circuit boards. Demand for
heavy yarns in North America has also decreased due, in part, to an increase in
imports of rigid laminates and printed circuit boards into North America. To
offset the lower demand for heavy yarns, we shifted some of our capacity to
supply industrial and construction markets that have not been affected by the
turmoil in Asia. Management believes the volume of heavy yarn sales for
electronic applications is stabilizing thus far in 1999, though pricing
pressures are expected to continue.

  Cost of Sales. Cost of sales consists of raw materials, energy, labor and
manufacturing overhead. These components of cost of sales as a percentage of
total cost of sales averaged 26.6% for raw materials, 8.2% for energy, 23.0%
for direct labor, 17.9% for period labor and 24.3% for manufacturing overhead,
from 1996 to 1998. On a pro forma basis, cost of sales would have increased by
$7.1 million for 1998 primarily as a result of increases in the costs of raw
materials, pension expense and depreciation related to the formation
transactions.

  Selling, General and Administrative Expenses. Selling, general and
administrative expenses consist of the cost of our employees, including
technology personnel, and the estimated costs of corporate services provided by
Owens Corning.

  Other Income, net. Other income consists of royalties and technical service
fees earned from a non-exclusive license granted by us to Taiwan Glass
Industrial Corporation. The historical financial statements only include the
portion of the royalties and fees attributable to the manufacture and sale of
glass yarn products by Taiwan Glass. Other income also includes the net profit
arising our sales of byproducts generated in the manufacturing process and
interest income.

  Adjusted EBITDA. Adjusted EBITDA is defined as net income or loss before
income taxes and extraordinary item, interest expense, depreciation and
amortization expense, non-recurring charges of $2.3 million in 1998 and $.3
million for the three months ended March 31, 1999 and restructuring charges of
$2.0 million in 1998. Adjusted EBITDA is presented because it is a widely
accepted financial indicator of a company's ability to service indebtedness;
however, adjusted EBITDA should not be considered as an alternative to net
income or loss, as a measure of operating results or to cash flows as a measure
of liquidity in accordance with generally accepted accounting principles.
Adjusted EBITDA as presented in this prospectus may not be comparable to
similarly titled measures reported by other companies as they are not
calculated identically by all companies.

Three Months Ended March 31, 1999 Compared to Three Months Ended March 31, 1998

  Net Sales. Net sales decreased $10.9 million, or 15.0%, to $62.0 million in
the three months ended March 31, 1999 from $72.9 million in the three months
ended March 31, 1998. This decrease was due primarily to reduced sales in the
electronic and construction industries as well as decreased

                                       27
<PAGE>

demand for heavy yarns used in rigid printed circuit boards. The decrease was
partially offset by increased sales for industrial and specialty applications.

  Gross Profit. Gross profit margins decreased from 34.0% for the three months
ended March 31, 1998 to 32.3% for the three months ended March 31, 1999. This
decrease is attributable to price pressure on the electrical market, primarily
heavy yarns. Additionally, fabrication costs increased due to the supply
agreement with Owens Corning in effect for the first quarter of 1999. 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 8.1%, from 5.3%, of net sales for the
three months ended March 31, 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, income
from operations decreased $6.8 million to $12.1 million, or 19.5% of net sales,
for the three months ended March 31, 1999, from $18.9 million, or 26.0% of net
sales, in the three months ended March 31, 1998.

Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

  Net Sales. Net sales decreased by $8.8 million, or 3.2%, from $277.4 million
for 1997 to $268.6 million for 1998. This decrease was due primarily to
decreased demand for heavy yarns used in rigid printed circuit boards which
began in the fourth quarter of 1997 and the effects of a stronger U.S. dollar
on sales in Europe. This decrease was partially offset by slight increases in
overall pricing and increased sales for construction and specialty
applications.

  Gross Profit. Gross profit decreased by $4.1 million, or 4.3%, from $95.0
million for 1997 to $90.9 million for 1998. Gross profit decreased as a
percentage of net sales from 34.2% for 1997 to 33.8% for 1998. Excluding the
non-recurring and non-cash charges of $1.9 million, gross profit increased from
34.2% for 1997 to 34.5% for 1998. This increase was primarily due to a more
favorable, higher margin product mix and decreased labor costs resulting from
personnel reductions at our Huntingdon and Aiken facilities, which were part of
a restructuring plan that was implemented in the first quarter of 1998. This
increase was partially offset by a decrease in sales combined with price
pressure on heavy yarns used in electronic rigid printed circuit boards, as
well as an increase in prices paid to Owens Corning for raw materials after
consummation of the formation transactions.

  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased by $1.4 million, or 9.4%, from $14.8 million
for 1997 to $16.2 million for 1998. Selling, general and administrative
expenses increased as a percentage of net sales from 5.3% for 1997 to 6.0% for
1998. The increase was due to the establishment of independent operational,
management and information system costs, and relocation costs in connection
with the formation transactions.

  Restructuring Costs. In the first quarter of 1998, we decided to reduce
personnel at our Aiken and Huntingdon facilities by approximately 100 employees
during 1998. In connection with the

                                       28
<PAGE>

planned personnel reduction, we recorded a $2.0 million charge representing
severance costs associated with the positions to be eliminated. We realized
cost savings as a result of our restructuring plan during 1998 and expect to
realize further cost savings for the foreseeable future.

  Income from Operations. Income from operations decreased by $10.3 million, or
12.8%, from $80.2 million for 1997 to $69.9 million for 1998. Excluding the
impact of the restructuring costs, non-recurring charge and amortization of
intangibles described above, income from operations decreased by $3.2 million
or 3.9% from $80.2 million for 1997 to $77.0 million for 1998. This decrease
was primarily related to the factors discussed above.

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

  Net Sales. Net sales increased by $2.4 million, or 0.9%, from $275.0 million
for 1996 to $277.4 million for 1997. This increase was due primarily to
increased sales volumes of fine yarn products partially offset by lower overall
pricing.

  Gross Profit. Gross profit increased by $0.4 million, or 0.4%, from $94.6
million for 1996 to $95.0 million for 1997. Gross profit decreased as a
percentage of net sales from 34.4% for 1996 to 34.2% for 1997. The increase in
gross profit was primarily due to increased sales volumes of higher margin fine
glass yarns. The decrease in gross profit as a percentage of net sales was
primarily due to lower overall pricing.

  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased by $0.5 million, or 3.5%, from $14.3 million
for 1996 to $14.8 million for 1997. Selling, general and administrative
expenses increased as a percentage of net sales from 5.2% for 1996 to 5.3% for
1997. The increase was due to normal increases in compensation expenses.

  Income from Operations. Income from operations decreased by $0.1 million, or
0.1%, from $80.3 million for 1996 to $80.2 million for 1997. The decrease was
primarily related to overall pricing decreases.

Liquidity and Capital Resources

  Historically, our primary sources of liquidity were cash flows from
operations. Since the consummation of the formation transactions on September
30, 1998, 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 three months ended March 31, 1999, net cash provided by operating
activities increased $15.9 million from $12.8 million for 1998 to $28.7 million
for 1999. The increase was primarily attributable to an increase in the amount
of $14.8 million payable to Owens Corning under the transitional services
agreement and an increase of accounts payable of $2.1 million and accrued
liabilities of $8.6 million, offset by a reduction of net income, before
extraordinary item and depreciation and amortization of $4.7 million and an
increase in accounts receivable of $4.8 million.

  Net cash provided by operating activities decreased from $65.3 million for
1997 to $47.2 million for 1998. This decrease was primarily attributable to
lower net income before depreciation, amortization and nonrecurring charge to
inventory in 1998 as compared to 1997 and an increase in accounts receivables
of $14.3 million and inventory of $6.0 million in 1998. The increase in
accounts receivable was due to our offering of incentives in 1997 for early
payment and an increase in days sales outstanding. Incentives were not offered
in 1998. Inventory increased due to lower shipments in

                                       29
<PAGE>

the last quarter of 1998 compared to 1997. This was partially offset by higher
depreciation and amortization in 1998 than in 1997 due to the step-up in basis
and intangible assets recorded in conjunction with the formation transactions
in 1998. Net cash used in investing activities increased from $8.3 million for
the year ended December 31, 1997 to $16.8 million for the year ended December
31, 1998. The increase in cash used in investing activities was due to capital
expenditures which were primarily for the construction of a glass yarns
manufacturing facility in South Hill, Virginia and rebuilding of glass melting
furnaces.

  Net cash provided by operating activities increased from $62.1 million for
1996 to $65.3 million for 1997. This increase was primarily the result of a
decrease in inventory levels of $1.7 million, a reduction in accounts
receivable of $3.5 million and an increase in accounts payable of $3.4 million
in 1998 all of which were attributable to more aggressive management of working
capital. These increases in cash flows from operations, were partially offset
by a decrease in accrued liabilities and income taxes payable of $6.8 million
relating primarily to incentive compensation accruals. Net cash used in
investing activities decreased from $15.3 million for 1996 to $8.3 million for
1997. This decrease was due to the reduction in expenditures for refurbishing
capital equipment, particularly rebuilding glass melting furnaces.

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

  . 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;

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

  .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 secured 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 March 31, 1999, $241.6 million was outstanding
under the senior credit facility and we had availability thereunder equal to
approximately $66.6 million. See "Description of Other Indebtedness--Senior
Credit Facility."

  We also entered into a senior subordinated credit facility with various
lenders. First Union Investors, Inc. and Warburg Dillon Read LLC served as co-
agents under the senior subordinated credit facility. The senior subordinated
credit facility provided for aggregate borrowings of up to $150.0 million and
was fully drawn at the closing of the formation transactions. The senior
subordinated credit facility was an unsecured senior subordinated obligation.

  On January 21, 1999, we sold the old notes. The net proceeds of the offering
of the old notes, together with additional borrowings under the senior credit
facility, were used to repay all amounts outstanding under the senior
subordinated credit facility. See "Use of Proceeds." As part of the offering of
the old notes, we agreed to exchange the old notes for exchange notes as
discussed in this prospectus. Interest expense on an as adjusted pro forma
basis, after giving effect to the formation transaction, the sale of the old
notes and the exchange of the old notes for exchange notes, was $38.7 million
for 1998 and $9.5 million for the three months ended March 31, 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 $15.3 million,
$8.3 million, $16.8 million and $3.2 million for 1996, 1997 and 1998, and the
three months ended March 31, 1999, respectively. We expect to make

                                       30
<PAGE>

annual capital expenditures aggregating approximately $18.0 million in 1999.
The increase in capital expenditures in 1998 was primarily as a result of
approximately $9.0 million of expense incurred in connection with the start-up
of the South Hill facility and increased expenses incurred to finance furnace
rebuilds. We anticipate that capital expenditures incurred in 1999 will be made
for routine maintenance and rebuilds of glass melting furnaces and other
equipment used in its operations. We also intend to spend approximately $2.8
million for new management information systems in 1999. In addition, we intend
to build a new melter at our Aiken facility in 2000. We estimate that the cost
to construct this melter will be approximately $49.0 million; however, in
connection with the construction of the melter, we plan to reduce expenses
associated with the rebuild of furnaces by approximately $12.0 million. The
cost of the management information system and the construction costs for the
melter are expected to be funded by cash flows from our operations. In
addition, we have minimum future rental commitments associated with operating
leases of $6.8 million through 2002. See Note 9 to the Financial Statements.

  In connection with Porcher Industries' purchase of a 51% interest in Advanced
Glassfiber Yarns, we have made a partnership election to step up the basis of
some of our intangible assets. The resulting increase in amortization expense
will allow the consolidated U.S. tax group of Porcher Industries (which
includes BGF Industries, hereinafter "Porcher U.S.") to significantly reduce
its tax liability, and as a result, Porcher U.S. has agreed to defer the
receipt of annual distributions which we were otherwise required to make in
order to fund those taxes, to the extent that such taxes relate to income
earned by us (the "Deferred Distributions"). The amortization deductions may be
challenged by the IRS; however, we believe the amortization deductions are
valid and that we are likely ultimately to prevail in any challenge. If,
however, the amortization deductions are disallowed, we will be required to
distribute all accumulated annual Deferred Distributions to the extent that
both before and after such distribution there is not a default under the senior
credit facility or the notes. Moreover, all Deferred Distributions would cease,
and we would have to pay in full all future distributions for taxes to Porcher
U.S. Based on the purchase price paid by Porcher U.S. for the 51% interest in
Advanced Glassfiber Yarns, and a 15 year amortization period, the maximum
annual Deferred Distribution will be $6.8 million. The actual amounts of
Deferred Distributions may be less if Porcher U.S.'s share of taxes due with
respect to income earned by us is less than $6.8 million. We believe adequate
funds will be available from net cash flows and borrowings under the senior
credit facility to fund the Deferred Distributions.

  The collective bargaining agreement with employees at our Aiken plant expires
on June 30, 1999 and the collective bargaining agreement with employees at our
Huntingdon plant expires on October 31, 1999. Although we cannot provide any
assurances, we believe that we will be able to successfully negotiate new
collective bargaining agreements with these labor unions on satisfactory terms
in the future. However, if we cannot successfully negotiate these new
collective bargaining agreements, our liquidity and results of operations could
be adversely affected.

  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 general 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

                                       31
<PAGE>

credit facility in an amount sufficient to enable us to service our
indebtedness, including the notes, or to fund our other liquidity needs,
including the construction of a new melter at our Aiken facility. In addition,
we may need to refinance all or a portion of the principal of the notes on or
prior to maturity. We cannot assure you that we will be able to effect any such
refinancing on commercially reasonable terms or at all.

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 the notes to our consolidated financial statements for a
description of our accounting policies and other information related to these
financial instruments.

  Our senior credit facility is subject to market risks, including interest
rate risk. Our financial instruments are not currently subject to foreign
currency risk or commodity price risk. We have no financial instruments held
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 March 31, 1999, we had two
interest rate swap agreements effective through September 30, 2003 and 2005 on
an initial notional amount of $240 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 changes our payment of interest on
$240 million of variable rate debt for the contract period.

  The fair value of the interest rate swap agreement represents the estimated
receipts or payments that would be made to terminate the agreement. At March
31, 1999, we would have received approximately $6.6 million to terminate the
agreements. A 1% decrease in LIBOR would decrease the amount received by
approximately $8.8 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 counterparties 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.

Inflation and Seasonality

  We believe that neither inflation nor seasonality had a material impact on
our results of operations for 1996, 1997 or 1998. We do, however, experience a
comparative reduction in net sales during the months of August and December due
to vacation and holiday schedules.

Year 2000

  Introduction. The term "year 2000 issue" is a general term used to describe
the various problems that may result from the improper processing of dates and
date-sensitive calculations by computers and process control equipment as the
year 2000 is approached and reached. These problems generally arise from the
fact that most of the world's computer hardware and software have historically
used only two digits to identify the year in a date, often meaning that the
computer will fail to distinguish dates in the "2000s" from dates in the
"1900s." These problems may also arise from other sources as well, such as the
use of special codes and conventions in software that make use of the date
field. The year 2000 issue could effect both information technology ("IT") and
non-information technology ("non-IT") systems.

  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:

  .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.

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

  .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.

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

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

                                                    the second quarter of 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 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. Two-thirds of these suppliers have responded
that they are or expect to be year 2000 compliant. Although we have not
received responses from the final one-third 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 67% of our sales as of
March 31, 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.

<PAGE>

  Costs to Address the Year 2000 Issue. As of March 31, 1999, we had spent
approximately $.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 $2.8 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 $1.5 million in the second
quarter of 1999 and approximately $0.5 million in the third 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 systems replacements.
We expect to capitalize approximately $1.5 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.

  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.


                                       35

  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 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

  Statement of Financial Accounting Standards No. 131, "Disclosures about
Segments of an Enterprise and Related Information" became effective in 1998. We
have provided comparative disclosures in accordance with the provisions of this
statement.

  SFAS No. 132, "Employers' Disclosure About Pensions and Other Postretirement
Benefits," became effective in 1998. We have provided comparative disclosures,
which include prior period information, in accordance with the provisions of

Advanced Glassfiber Yarns

  We are the second largest global supplier of glass yarns. In 1997, our net
sales accounted for approximately 49% of the North American market and
approximately 24% of the global market. We are one of only two major glass
yarns producers with manufacturing facilities in North America and one of only
five major glass yarns producers that supply glass yarns globally. Our glass
yarns are produced by converting molten glass into thin glass filaments which
are then twisted into yarn. Our products fall into two categories based on
filament diameter:

  . heavy yarns, which accounted for 74% of our 1998 net sales and 74% of our
    first quarter 1999 net sales; and

  . fine yarns, which accounted for 26% of our 1998 net sales and 26% of our
    first quarter 1999 net sales.

  We are the world's largest producer of fine yarns, and the world's second
largest producer of heavy yarns.

  Glass yarns, because of their unique physical properties, are a critical
material used in a variety of electronic, industrial, construction and
specialty applications. Heavy yarns are used in a wide range of applications,
such as printed circuit boards, roofing materials, filtration equipment,
building reinforcements, window screening, aerospace materials and reinforced
tapes. Fine yarns are used primarily to construct laminates for multi-layer
printed circuit boards, which are integral to virtually all advanced electronic
products, including computers, telecommunications equipment, television
equipment, automotive equipment and home appliances. We also produce a
subcategory of heavy yarns known as specialty materials, such as S-2 Glass(R),
a proprietary high-strength glass yarn. Specialty materials, which accounted
for 10% of our 1998 net sales and 12.0% of our first quarter 1999 net sales,
are used for aircraft laminates, oxygen tanks, sporting goods and vehicle
armor. Fine yarns and specialty materials generally command higher prices and
profit margins than non-specialty heavy yarns, primarily due to their value-
added characteristics.

  Attractive Industry Fundamentals. The glass yarns industry has historically
been characterized by a limited number of suppliers, high barriers to entry, a
limited number of cost-effective substitutes and high capacity utilization.
There are only five major glass yarns producers that supply glass yarns
globally, with combined sales comprising approximately 80% of total industry
sales. Historically, new entry into the market has been limited due to high
barriers of entry, which include technological know-how and significant capital
expenditure requirements. In addition, we believe that the industry's capacity
utilization generally has been high, which has allowed manufacturers to more
efficiently operate their facilities. Our capacity utilization, as measured by
use of installed bushings, averaged approximately 92% between 1996 and 1998.

  Stable Customer Base.  We sell our products to over 300 customers worldwide,
including every major North American and European weaver and a diverse group of
other domestic and international commercial and industrial users of yarns. We
maintain long-standing relationships with our major customers by collaborating
with them to meet their specific manufacturing requirements and by providing
high quality products and strong customer service. In addition, our customer
relationships generally are stable due to the limited number of global
suppliers of glass yarns and the

                                       37
<PAGE>

costs to customers associated with "qualifying" new suppliers. In order to
qualify a new supplier, a customer may need to modify its own loom set-ups and
fabric specifications and also qualify the new glass yarn supplier with
downstream manufacturers and weavers. Furthermore, although glass yarns
generally represent a small fraction of an end product's overall manufacturing
cost, product defects can be costly for customers. Consequently, customers
demand high-quality, reliable yarns from their suppliers and we have
established a reputation with our customers for meeting these demands. As a
result of these factors, we have maintained relationships with each of our top
five customers for over 25 years.

  Unique Properties of Glass Yarns. The characteristics of glass yarns include:

  . high strength-to-weight ratio;

  . dimensional stability;

  . heat resistance;

  . moisture resistance;

  . chemical resistance;

  . electrical resistance; and

  . thermal insulation.

Although carbon and aramid fibers are stronger than glass yarns, they are
significantly more expensive. Other materials, such as steel and wood, are less
expensive but lack the physical characteristics of glass yarns. Given the
unique combination of physical attributes and relative low cost of glass yarns,
we believe few cost-effective substitute products exist.

  Diversified End-Use Markets. The characteristics of glass yarn make it the
material of choice for a variety of products manufactured in the electronics,
industrial, construction and specialty markets. Our net sales to these markets
represented 32.3%, 28.4%, 29.9% and 9.4% of our 1998 net sales, respectively,
and 28.1%, 35.0%, 25.0% and 11.9% of our first quarter 1999 sales,
respectively. We believe that this diversity in end-use applications reduces
volatility in overall demand for our products.

  Superior Production Technology and Product Innovation. We believe that we are
the technological leader in the production of glass yarns due to our strong
process engineering and product development capabilities. We pioneered the
glass yarns industry with the introduction of "glass cotton" in the 1930s and
the introduction of fine yarns in the 1940s, and have continued our innovation
with the development of S-2 Glass(R), Zentron(R) and zero twist yarn. We employ
41 technical professionals dedicated to the development of new products,
process improvements and product innovations.

Business Strategy

  Our business strategy includes the following key elements:

  Emphasize Fine Yarns and Specialty Materials. We will continue our focus on
increasing the proportion of our net sales attributable to fine yarns and
specialty materials. Sales of fine yarns and specialty materials increased as a
proportion of net sales from 26% in 1994 to 36% in 1998 and 38% in the first
quarter of 1999. We believe our global leadership in producing fine yarns and
specialty materials is a competitive advantage when targeting manufacturers of
sophisticated electronics and specialty composites.

                                       38
<PAGE>

  Develop New Products and Product Innovations. To maintain our technological
leadership position in the glass yarns industry, we conduct an active internal
research and development program aimed at developing new and improved products.
In addition, we have formed several joint product development programs with our
customers such as BGF Industries, a wholly-owned subsidiary of Porcher
Industries, and downstream manufacturers. We also have a continuing
relationship with Owens Corning pursuant to which we and Owens Corning conduct
joint development programs and share in Owens Corning's technology and research
and development. We will continue our focus on research and development and our
commitment to collaborate with our customers to improve and develop products.

  Focus on Operating Efficiency. We continually seek to improve the quality of
our production facilities and our operating systems by utilizing modern
production technology. These new technologies have enabled us to increase
throughout, product quality and operational flexibility.

  Selective Geographic Expansion. We believe that we have opportunities to
expand our business outside of North America. Approximately 25.7% of our 1998
net sales were outside of North America, with approximately 21.3% in Europe and
approximately 4.4% in Asia. Approximately 26.9% of our first quarter 1999 net
sales were outside of North America, with approximately 24.9% in Europe and
approximately 2% in Asia. We believe that Asia represents an attractive long-
term opportunity for sales of our fine yarns, despite the region's current
economic turmoil. Some of our customers are expanding their production
capabilities in Asia to meet the region's demand for glass fabrics used to
manufacture electronic laminates. We anticipate that glass yarns needed for
such increased production will be sourced locally. According to the U.S.
Department of Commerce, the Asian and Australian regions represented
approximately 50% of the global supply of printed circuit boards in 1997. Our
strategy is to continue to expand outside North America by co-locating or
sharing production facilities with our customers. This would reduce the risks
and capital expenditures associated with geographic expansion while
strengthening our relationships with these customers.

  Advanced Glassfiber Yarns is a Delaware limited liability company with
headquarters located at 2556 Wagener Road, Aiken, South Carolina 29801. Our
telephone number is (803) 643-1377.

Products

  Our products are produced based on weight and strength specifications
developed in close cooperation with customers. Our products fall into two
categories based on filament diameter:

  .heavy yarns, with a filament diameter between 7 and 14 microns, which
    accounted for 74% of our 1998 net sales and 74% of our first quarter 1999
    sales; and

  . fine yarns, with a filament diameter generally up to 7 microns, which
    accounted for 26% of our 1998 net sales and 26% of our first quarter
    1999 sales. Products with finer diameters generally command higher
    prices.

  Heavy Yarns. Heavy yarns are used for a wide range of applications, such as
printed circuit boards, roofing materials, filtration equipment, building
reinforcements, window screening, aerospace materials and reinforced tapes.
Currently, prices for heavy yarns, excluding specialty materials, range from
approximately $2.00 to $4.00 per kilogram. We also produce a subcategory of
heavy yarns known as specialty materials, such as S-2 Glass(R), a proprietary
high strength glass yarn. Specialty materials, which accounted for 10% of our
1998 net sales and 12% of our first quarter 1999 sales, are used for aircraft
laminates, oxygen tanks, sporting goods and vehicle armor. Currently, prices
for specialty materials range from approximately $12.00 to $29.00 per kilogram.

                                       39
<PAGE>

  Fine Yarns. Fine yarns, which require a significant level of technical
engineering expertise, generally command higher prices than non-specialty heavy
yarns, and are primarily used to construct laminates in multi-layer printed
circuit boards. Printed circuit board customers require a material that yields
a highly uniform, flat surface. We are the world's largest producer of fine
yarns and believe that our technological leadership differentiates us from our
competitors. Currently, prices for fine yarns range from approximately $4.00 to
$10.00 per kilogram.

Marketing and Sales

  We primarily sell to glass yarn weavers who weave glass yarn into fabric
ultimately used in a wide variety of end-use applications. Our customers
include, among others, every major glass weaver in North America and Europe. We
have a customer base of approximately 300 customers. Our top five and top ten
customers accounting for 57% and 67% of our 1998 sales, respectively and 55%
and 67% of our first quarter 1999 sales, respectively. Our top five customers
are Porcher Industries, including its affiliates such as BGF Industries, Clark-
Schwebel, Inc., Bay Mills Limited, Hexcel Corporation and JPS Converter and
Industrial Corp. Among the different markets in the glass yarns industry, the
electronic market is characterized by a few major customers, each with a strong
relationship with us but that generally qualify more than one supplier; the
industrial and construction markets are characterized by many customers that
generally qualify only one supplier; and the specialty market is characterized
by customers that require highly specialized yarns produced in a cooperative
effort with the supplier and, consequently, generally qualify only one
supplier.

                                       40

  We market our products primarily through a direct sales force with offices
located in the United States, Europe and Asia. Our North American customers are
serviced by four sales personnel and one sales manager; Europe is serviced by
three sales personnel and Asian customers by one sales representative. The
marketing and business planning organization consists of four persons,
including two marketing managers, industrial and construction and electronic,
and two product segment leaders, Europe and Asia and North America.

(1) The South Hill facility is a co-location facility shared with BGF
    Industries, at which we and BGF Industries work together closely to
    coordinate the production of glass yarns for use solely by BGF Industries'
    operations at that facility. We opened the facility in June 1998 and it
    became fully operational in the first quarter of 1999. See "Related Party
    Transactions."
(2) We own all of the equipment located in the South Hill facility, but lease
    the building from BGF Industries.

  In addition to the facilities that we own or lease, subsidiaries of Owens
Corning that operate facilities in Battice, Belgium and Guelph, Ontario have
historically provided us with specific products, primarily heavy yarns, to
serve segments of the European and North American markets. Although these
facilities have been retained by Owens Corning, we entered into contracts to
purchase specific glass yarns manufactured at these facilities. See "Related
Party Transactions."

Manufacturing Process

  Glass yarns are manufactured by mixing raw material at high temperatures to
create molten glass which flows through a bushing to create continuous glass
strands. These strands are spooled, and then twisted to create glass fiber
yarns. We employ two types of manufacturing processes for glass yarns, "direct
melt" and "indirect melt."

  The "direct melt" glass fiber manufacturing process, which is employed at the
Aiken facility, begins when finely ground raw materials, including sand,
limestone, clay, borates and specialty chemicals, are blended together in a
bulk quantity called the "batch." The batch is then fed into a furnace where it
is melted at 2,600 degrees Fahrenheit in refractory-lined furnaces. The molten
glass

                                       41
<PAGE>

flows to numerous heat-resistant platinum and rhodium trays called bushings.
These bushings have thousands of small, precisely drilled tubular openings
through which glass flows and becomes filaments. The hair-like filaments are
coated with an aqueous chemical mixture called "sizing," which protects the
filaments during processing and handling, including weaving or braiding, and
ensures good adhesion of the glass fiber to the resin when manufacturing
polymer reinforcements.

  After sizing is applied, filaments are gathered together into strands that go
through further processing steps depending on the market into which the fiber
will be sold. The filaments are wound onto intermediate packages by high speed
winders. In most cases, the strands are unwound from the intermediate packages
and are twisted together to form glass fiber yarns that are rewound onto
bobbins for sale to customers.

  The Huntingdon facility and the South Hill facility employ a marble melt
process, known as "indirect melt," to manufacture fine glass fiber yarns using
glass marbles as the principal raw material. The glass marbles are melted in
individual furnaces and pulled through bushings to form filaments. The
filaments are sized, wound onto intermediate packages, and twisted in the same
manner as in the direct melt process. The advantage of the indirect method is
that each bushing has its own melting device. This process, which we pioneered,
allows us to add incremental production capacity with more reasonable capital
expense and construction time and results in a more consistent product.

Competition

  We believe that the principal competitive factors affecting the glass yarns
industry include the quality, performance, product pricing and consistency of
products, response to customer requirements and stability of business
relationships with customers.

  We are one of only five major producers of glass yarns that supply their
products globally. The other global suppliers are PPG, Vetrotex, Nitto and
Nippon Electric. Sales by the five global suppliers accounted for approximately
80% of total 1997 industry sales. In addition to the five global suppliers of
glass yarns, there are two significant regional manufacturers, Taiwan Glass, a
licensee of our technology, and Nan Ya Plastics Corp., a licensee of PPG's
technology, each of which operates and has significant sales in Asia. We and
PPG are the only major producers of glass yarns with production facilities in
North America. However, Vetrotex has announced that it intends to build a plant
for the production of glass yarns, primarily for the electronics market, in
Mexico. Vetrotex has publicly stated that it expects this new plant to begin
operations in the second half of 1999.

Research and Development

  To maintain our leadership position in the glass yarns industry, we conduct
an active research and development program aimed at improving our manufacturing
processes and developing new and improved products. The research and
development program is managed by our science and technology group. We spent
$5.7 million, $5.9 million, $5.9 million and $1.6 million to fund the science
and technology group in 1996, 1997, 1998 and the first quarter of 1999,
respectively. A portion of the science and technology group dedicate their
efforts to the technical services organization ("TSO"). The Aiken and
Huntingdon facilities each have a TSO which is organized into technical teams
around each major customer category. The TSO teams in Aiken and Huntingdon are
staffed by 19 and 12 people, respectively. The TSO carries out ongoing process
and product improvements and each technical team is led by a product engineer,
who is supported by one or more

                                       42
<PAGE>

process experts responsible for troubleshooting manufacturing problems. TSO
teams also have a project engineering group which is responsible for capital
projects. The remaining persons in our science and technology group are experts
in chemistry, chemical applications and process development. A total of seven
employees perform the science and technology function at the Aiken facility.

  We have numerous United States patents, patent applications and trademarks.
While we consider our patents to be valuable assets, we do not believe that our
competitive position is dependent on patent protection or that our operations
are dependent on any individual patent or group of related patents. However, in
some instances, patents and patent protection may deter entry by new
competitors with respect to some of our product lines. Our policy is to obtain
patents on our new products and enforce our patent rights. In connection with
the formation transactions, Owens Corning assigned and licensed to us patents,
know-how, marks and business information relating to or used in our business.
In addition, we entered into a support services agreement with Owens Corning
pursuant to which they will cooperate with respect to research and development.
See "Related Party Transactions."

Raw Materials and Other Supplies and Sources

  The major raw materials used by us in the production of glass yarns are glass
marbles at the Huntingdon facility, and silica and borates at the Aiken
facility. We purchase glass marbles from Owens Corning pursuant to an exclusive
seven year supply agreement. Silica is readily available and is currently
provided to us by a number of local suppliers. We primarily use borates in our
production processes at our Aiken facility, which are sourced from a supplier
in Turkey that is owned by the Turkish government. Our supply of borates from
Turkey is sourced through Owens Corning under a supply agreement which provides
that, if there is a limited or reduced supply of borates, Owens Corning will
allocate a portion of such supply to us.

  In addition to the raw materials involved in the production of glass yarns,
we use specialized capital equipment, such as bushings. Bushings are heat-
resistant platinum and rhodium trays through which molten glass is filtered to
produce glass filaments. Our bushings are currently manufactured and
periodically reconditioned by Owens Corning. Owens Corning has agreed to
continue to provide bushings to us and reconditioning service for the bushings
for a period of seven years. See "Risk Factors--We have only operated
independently of Owens Corning since September 30, 1998 and remain dependent
upon Owens Corning to provide materials and services" and "Related Party
Transactions."

Employees

  As of March 31, 1999, we had approximately 1,495 full-time employees. As of
that date, approximately 1,350 of the employees were engaged in manufacturing
and related services. Production, maintenance, warehouse and shipping employees
at our Aiken facility are represented by Teamsters Local Union Number 86, an
affiliate of the International Brotherhood of Teamsters. The collective
bargaining agreement with this union covering our employees at Aiken expires on
June 30, 1999. Production, maintenance, warehouse and shipping employees at our
Huntingdon facility are represented by the Union of Needletrades, Industrial
and Textile Employees and its local 1034T. The collective bargaining agreement
with this union covering our employees at Huntingdon expires on October 31,
1999. Management considers our labor relations to be generally good.

Environmental Matters

  Our past and present operations, including our ownership and operation of
real properties, are subject to extensive and changing federal, state, local
and foreign environmental laws and requirements, including, among others, those
governing discharges to air and water, the handling and disposal of soils and
hazardous substances and wastes, and the remediation of contamination
associated with releases of hazardous substances at our facilities and off-site
disposal locations. Our operations are also governed by laws and requirements
relating to workplace safety and health. Management believes that we are
generally in material compliance with these laws and requirements.

  We cannot assure you that we will not in the future incur costs or
liabilities relating to environmental or health and safety matters, including
those relating to compliance with laws and requirements, remediation of
contamination, or claims by third parties.

  We, like all manufacturers of glass yarns, are subject, in various
jurisdictions, to laws and regulations designed to reduce solid wastes by
requiring, among other things, use of materials producing waste to be
degradable in landfills, minimum levels of recycled content, various recycling
requirements, disposal fees and limits on the use of harmful products. In
addition, various consumer and special interest groups have lobbied from time
to time for the implementation of additional environmental protection measures.
We do not believe that either the legislation promulgated to date or currently
pending initiatives will have a material adverse effect on our business. There
can be no assurance that any future legislation or regulatory efforts will not
have a material adverse effect on our business, financial condition or results
of operations.

  In connection with the formation transactions, Owens Corning retained all
liabilities resulting from the presence of hazardous substances at or migrating
from the sites contributed by Owens Corning to us, as well as all liabilities
resulting from the transportation or arrangements made by Owens Corning for the
treatment, storage or disposal of hazardous substances to any off-site location
prior to September 30, 1998. We have not assumed any of these liabilities. In
addition, Owens Corning has agreed to indemnify us against any losses and
damages arising out of the environmental liabilities retained by Owens Corning.
However, with respect to environmental remedial action, Owens Corning's
indemnification obligations are limited to compliance with the standards set
under applicable environmental laws and these obligations will be satisfied
upon and to the extent of final approval of the remedial action by the
governing environmental authority.

                              OPERATING AGREEMENT

  The following is a summary of material terms of the Amended and Restated
Limited Liability Company Operating Agreement of Advanced Glassfiber Yarns
dated September 30, 1998. The summary does not restate the operating agreement
in its entirety. We have filed a copy of the operating agreement as an exhibit
to the registration statement which includes this prospectus.

Organization

  Advanced Glassfiber Yarns is a limited liability company formed under the
Delaware Limited Liability Company Act and is governed by the operating
agreement. As a result of the formation transactions, a wholly owned subsidiary
of Porcher Industries owns a 51% membership interest in Advanced Glassfiber
Yarns and a wholly owned subsidiary of Owens Corning owns the remaining 49%
membership interest. Our purpose is to manufacture and sell glass fiber yarns
and related specialty materials.

Duration

  Under the operating agreement, we will be dissolved upon the first to occur
of the following:

  .September 30, 2097;

  . upon agreement of the members;

  . at the election of one member, upon a material breach of the operating
    agreement by the other member which is not cured within 90 days following
    notice thereof; and

  . automatically upon the bankruptcy or liquidation of a member, unless the
    other member elects to continue us.

Governance

  The operating agreement provides that the Board of Directors manages our
business and affairs, subject to the terms and provisions of the operating
agreement. The Board of Directors is comprised of two directors designated by
Owens Corning and three directors designated by Porcher Industries. Owens
Corning's right to designate two directors would terminate at such time as it
no longer holds at least a 10% ownership interest. Actions of the Board of
Directors require a quorum of at least a majority of the Board, including at
least one director representing each member.

  Robert Fisher, formerly Owens Corning's manager of the business prior to the
formation of Advanced Glassfiber Yarns, has been designated in the operating
agreement as our initial general manager. Porcher Industries has the exclusive
right under the operating agreement to appoint the chief executive officer and
the chairman of our Board of Directors. All of our other executive officers are
to be designated by the Board of Directors.

  The following actions require the approval of 75% of a specified quorum of
the Board of Directors:

  . the termination of Mr. Fisher during the first year of his employment as
    our initial general manager;

  . the issuance of additional ownership interests;


                                       47
<PAGE>

  . materially changing our business plan or type of business or engaging in
    a new business;

  . effecting any merger, consolidation, plan of exchange or similar
    transaction to which we are a party;

  . selling all or a substantial portion of our assets other than in the
    ordinary course of business;

  . mortgaging or otherwise encumbering our assets other than in connection
    with our financing facilities;

  . except for specified distributions and in connection with the exercise of
    the Put Right (as defined herein), effecting a distribution of any of our
    assets, including cash, to any member;

  . effecting our liquidation or dissolution;

  . the redemption of any ownership interest other than in connection with
    the Put Right;

  . entering into any contract with any of our affiliates or with any member
    except as described in "Related Party Transactions" other than in
    connection with the Put Right;

  . making any tax election which is materially detrimental to us or any
    member;

  . the sale, license or other disposition to a third party, including, but
    not limited to any affiliate of a member, of Owens Corning technology
    that Owens Corning assigned or licensed to us;

  . incurring indebtedness other than:

   (1) indebtedness necessary in connection with the Put Right;

   (2) as required to effect specified distributions; and

   (3) borrowings under the Revolver (as defined herein) which do not exceed
      $75 million in the aggregate; or

  . materially amending any of our business, health, safety and environmental
    policies.

  All actions of the members require the presence and the affirmative vote of
members holding at least 75% of the outstanding ownership interests. Owens
Corning's right to require supermajority board approval of any of the actions
listed above, except for:

  . the issuance of additional ownership interests; and

  . the sale, license or other disposition to a third party, including, but
    not limited to, any affiliate of a member, of Owens Corning technology
    that Owens Corning assigned or licensed to us, would terminate whenever
    it no longer holds at least a 10% ownership interest.

Transfers of Ownership Interests; Registration Rights

  Under the operating agreement, no member may transfer its ownership interest
prior to September 30, 2003 without the prior written consent of the other
member. In the event a member thereafter decides to sell its ownership
interest, the non-selling member has a 30-day right to make an offer for such
ownership interest. If, within the 30-day period, the non-selling member fails
to make an offer, or the selling member rejects the non-selling member's offer,
the selling member is free to sell its ownership interest to any third party.

  At any time beginning on September 30, 2003, each member has a "Put Right"
which is the right to sell all of its ownership interest to us in the event the
conditions described below are satisfied. If a member exercises its Put Right,
the value of such ownership interest will be determined by a third party or
parties according to the procedures and criteria set forth in the operating
agreement. Our obligation to purchase a member's ownership interest is
conditioned on our ability to

                                       48
<PAGE>

finance the purchase of the ownership interest from a third party lender while
maintaining or obtaining not less than a B rating by either Standard & Poor's
or Moody's on our then-outstanding unsecured debt after giving effect to the
purchase. Any member that exercises its Put Right must reimburse us for 25% of
expenses incurred by us in connection with purchasing such member's ownership
interest. In addition, our ability to fund the Put Right will be subject to the
covenants under the senior credit facility and the indenture for the notes.

  In the event we are unable to purchase all of a member's ownership interest
upon the exercise of its Put Right, the member may request in writing that we
file and use our reasonable best efforts to cause to become effective a
registration statement under the Securities Act, covering the registration of
its ownership interest, or the portion thereof designated by the member.

Tax Distribution

  Pursuant to the terms of the operating agreement, we will make an annual "Tax
Distribution" which is a distribution from our net cash flow and permitted
borrowings under the senior credit facility to each of Owens Corning and
Porcher U.S. in order to fund the taxes payable by each owner on their
proportionate share of our net ordinary income and net capital gain. In
connection with Porcher Industries' purchase of a 51% interest in us, we intend
to make a partnership election to step up the basis of some of our intangible
assets. The resulting increase in amortization expense will allow Porcher U.S.
to significantly reduce its tax liability. As a result, the Tax Distributions
will not be made on a pro rata basis and Porcher U.S. will have an unrecovered
distribution amount (the "Deferred Distribution"). The Deferred Distribution
will earn interest at the same rate of interest as the senior credit facility.
If the amortization deductions are disallowed, we will be required to
distribute all accumulated annual Deferred Distributions to the extent that:

  . both before and after the distribution there is not a default under the
    senior credit facility and the notes; and

  . there are funds to make the distribution from available cash or
    borrowings under the senior credit facility.

  Thereafter, all Deferred Distributions will cease and we will pay in full all
future Tax Distributions to Porcher U.S.

Indemnification

  Pursuant to the operating agreement, we will indemnify and hold each member
and its affiliates and their respective officers, directors, members,
stockholders, managers, agents and representatives, and members of our Board of
Directors and each officer, harmless from any and all losses, claims, damages,
costs, liabilities and expenses suffered or incurred by any of such persons
arising out of, resulting from, based upon or in connection with the management
or conduct of our business or affairs.

  The Board of Directors has been advised that, in the opinion of the SEC,
indemnification for liabilities arising under the Securities Act or the
Exchange Act is contrary to public policy and is therefore unenforceable,
absent a decision to the contrary by a court of appropriate jurisdiction.

Other Provisions

  The operating agreement generally prohibits members from disclosing
confidential information provided by another member in connection with our
business. The operating agreement also requires the members to enter a non-
competition agreement with us and each other with respect to our business. See
"Related Party Transactions--Non-Competition."

<PAGE>

                           RELATED PARTY TRANSACTIONS

  Prior to the formation of Advanced Glassfiber Yarns, many of the components
of the glass yarns and specialty materials business were owned, leased or
otherwise controlled by Owens Corning. These components include, among others,
manufacturing facilities and equipment, employees trained in the use and repair
of the equipment, access to raw materials, intellectual property rights and
know-how and agreements with sales representatives worldwide.

  In connection with the formation transactions, we entered into agreements
with Owens Corning and Porcher Industries and their respective affiliates to
facilitate our continuing operation. These agreements are intended to benefit
us and the other parties. However, they may result in conflicts of interest
between us and these related parties.

  The following are summaries of these agreements and, as such, are qualified
in their entirety by reference to the full text of the related agreements.
Unless otherwise indicated, all agreements referred to in this section were
dated September 30, 1998.

LLC Purchase Agreement

  Pursuant to an LLC purchase agreement, Porcher Industries purchased a 51%
interest in Advanced Glassfiber Yarns. See "The Formation Transactions." The
LLC purchase agreement required us to enter into the supply agreements
described below relating to the conduct of our business with Owens Corning,
Porcher Industries and their respective affiliates. The LLC purchase agreement
also requires each of Owens Corning and Porcher Industries to indemnify the
other from any and all losses which arise out of the breach by the other party
of any of its representations and warranties or any of its covenants contained
in the LLC purchase agreement.

Non-Competition

  Pursuant to a non-compete agreement, Owens Corning and Porcher Industries and
their respective affiliates agreed not to compete with us in the manufacture
and sale of particular glass yarns and specialty materials that we currently
produce. Owens Corning and Porcher Industries and their respective affiliates
generally may not manufacture or sell, among other things, such business
products, for the later of a five-year period beginning on September 30, 1998
or any date on which either Owens Corning or Porcher Industries owns less than
a 5% ownership interest in us. Owens Corning and its affiliates have retained
the right to manufacture limited types of glass yarns.

Employee Benefits

  Owens Corning permits our employees who were employed by Owens Corning before
September 30, 1998 ("Transferred Employees") to remain as participants in, be
covered by, or accrue benefits under, Owens Corning employee benefit plans. We
reimburse Owens Corning for the cost of this coverage. These arrangements will
terminate as of December 31, 1999, or earlier if we request. Although we do not
currently sponsor a defined benefit pension plan, we have agreed to pay amounts
associated with early retirement benefits under the Owens Corning Merged
Retirement Plan (the "OC Plan"). Specifically, Transferred Employees who, as of
September 30, 1998, did not qualify for an early retirement benefit under the
OC Plan will continue to receive credit toward eligibility for the early
retirement benefit for service with us. If a Transferred Employee remains

                                       50
<PAGE>

employed by us until he qualifies for early retirement, the OC Plan will treat
the Transferred Employee as having elected early retirement upon retirement
from us. We are obligated to pay Owens Corning the difference between the lump
sum benefit payable to the Transferred Employee as an early retiree and the
lump sum benefit payable to the Transferred Employee as a deferred vested
benefit on the date of retirement from us under the applicable provisions of
the OC Plan. These liabilities were estimated to be $5.1 million on the date of
the formation transactions. It has not yet been determined what pension
arrangements will be made after December 31, 1999 and whether or not we will
assume assets and liabilities attributed to benefits accrued as of September
30, 1998 relating to Transferred Employees under the OC Plan.

  In connection with the formation transactions, we assumed liabilities for
postretirement medical and life insurance benefits with respect to Transferred
Employees, which were estimated to be $12.0 million on the date of the
formation transactions.

Facilities Arrangements at Aiken

  Prior to the formation transactions, Owens Corning's glass yarn and glass mat
factories, located in adjacent plants in Aiken, South Carolina, shared a number
of facilities and services. As part of the formation transactions, Owens
Corning transferred to us its glass yarn plant in Aiken, while retaining
ownership of the glass mat plant. In order to preserve the efficiencies and
cost savings created by the sharing arrangements in existence before the
formation transactions, we and Owens Corning have entered into the agreements
described below.

  Aiken Sewer Agreement. We entered into a sanitary sewer agreement pursuant to
which we permit Owens Corning to use our sanitary system in Aiken for sanitary
wastewater discharges in exchange for the payment by Owens Corning of 50% of
the actual costs of maintaining our sanitary system. The sanitary sewer
agreement will terminate after a period of ten years, unless extended or
otherwise terminated as set forth therein.

  Aiken Wastewater Treatment Agreement. We entered into a wastewater treatment
agreement pursuant to which we treat at our wastewater treatment facility in
Aiken aqueous industrial and laboratory waste discharged by Owens Corning. In
exchange for such services, Owens Corning pays 22% of our actual costs of
operating the wastewater treatment facility. The wastewater treatment agreement
will terminate after a period of ten years, unless extended or otherwise
terminated as set forth therein.

  Aiken Stormwater Agreements. We entered into various stormwater agreements
pursuant to which:

 . we permit Owens Corning to discharge stormwater into our two stormwater
   ponds; and

 . Owens Corning permits us to discharge stormwater into Owens Corning's
   landfill sedimentation basin in Aiken.

Each party is individually responsible for any sampling and for complying with
their respective stormwater permits. The stormwater agreements will terminate
after a period of ten years, unless extended or otherwise terminated as set
forth therein.

  Aiken Landfill Agreement. We entered into a landfill agreement pursuant to
which Owens Corning permits us to use Owens Corning's landfill in Aiken for the
disposal of waste in exchange

                                       51
<PAGE>

for our payment of 50% of the actual costs of operating the landfill. The
landfill agreement is effective for the operating life of the landfill, unless
earlier terminated as set forth therein.

Facilities Arrangements at Huntingdon

  Huntingdon Lease. Owens Corning leases from us approximately 9,000 square
feet of our facility in Huntingdon, Pennsylvania for use as a glass mat
manufacturing and distribution facility. The lease will expire on September 30,
2003, unless extended or terminated as provided in the lease agreement. Owens
Corning pays a nominal fixed fee for the term of the lease plus its allocated
share of all building operating expenses, as calculated in the lease agreement.

  Huntingdon Air Modeling Agreement. Prior to the formation transactions, Owens
Corning treated its glass yarn and glass mat manufacturing operations in
Huntingdon as a single facility for environmental compliance purposes. As part
of the formation transactions, Owens Corning transferred to us the entire
facility in Huntingdon, a portion of which it leases back from us. In order to
maintain continuity in complying with air emission modeling requirements under
applicable environmental laws, we entered into an air modeling agreement
pursuant to which the parties will treat their respective facilities in
Huntingdon, including the portion leased to Owens Corning, as a single facility
for modeling current and/or projected air emissions. Although we have agreed to
share the costs of the modeling, each party remains solely responsible for its
own environmental liabilities, if any. The air modeling agreement will
terminate after a period of five years, unless extended or otherwise terminated
as set forth therein.

Subleases Relating to Equipment at Aiken and Huntingdon

  Prior to the formation transactions, Owens Corning leased equipment used in
the manufacturing of glass yarns at its Aiken and Huntingdon facilities. Owens
Corning agreed to sublease this equipment to us on substantially the same
economic terms as provided to Owens Corning in the original leases.

  At our Aiken facility, we sublease from Owens Corning, pursuant to Owens
Corning's master leases, some manufacturing equipment owned by Carly 1995
Leasing Trust and a vacuum treatment oven owned by Pitney Bowes Credit
Corporation. We sublease other manufacturing equipment from Owens Corning at
its Aiken and Huntingdon facilities pursuant to Owens Corning's master lease
with John Hancock Mutual Life Insurance Company. Specific terms of these
subleases are described below. If any of the master leases are terminated, all
of our rights under the related subleases will also terminate.

  Our sublease with Owens Corning relating to the Carly lease expires on
December 28, 2000. The sublease generally provides that we may purchase the
equipment at the termination of the sublease. We paid Owens Corning
approximately $100,000 pursuant to this sublease during the first quarter of
1999.

  The initial term of our sublease with Owens Corning relating to the Pitney
Bowes lease ends on March 31, 2001, but may be extended for up to two
additional years unless Owens Corning exercises its right to terminate the
sublease. The sublease generally provides that we may purchase the vacuum
treatment oven at the termination of the sublease. We incurred $400,000 of
expense pursuant to this sublease during the first quarter of 1999.


                                       52
<PAGE>

  The initial term of our sublease with Owens Corning relating to the John
Hancock lease ends on March 31, 2000, but may be extended for up to two
additional years unless Owens Corning exercises its right to terminate the
sublease. The sublease generally provides that we may purchase the equipment at
the termination of the sublease. We incurred $20,000 of expense pursuant to
this sublease during the first quarter of 1999.

Services Agreements

  We have entered into several agreements pursuant to which Owens Corning
performs services for us that are important to the success of our operations.
Some of these services agreements will only continue for a short time until we
hire and train our own personnel, while others are intended to continue for a
longer duration. These service agreements, which are described more fully
below, provide for the fabrication and repair of equipment, engineering and
technical services, sales agency agreements in Europe and administrative and
information systems services. In addition to the services provided by Owens
Corning, we perform manufacturing and distribution services for Owens Corning
at the Huntingdon facility, where Owens Corning continues to have operations.

  Alloy Services Agreement. We entered into an alloy services agreement
pursuant to which Owens Corning provides, at prices to be determined annually,
services relating to the alloying, fabrication and repair of bushings,
thermocouples and glass melter parts constructed from metal alloys. We have
generally agreed to use Owens Corning exclusively for these services. Owens
Corning has also agreed to manage our inventory of industrial precious metals
and metal alloys and to lease to us metal alloys for use in bushings,
thermocouples and glass melter parts at prices determined according to the
formula set forth in the alloy services agreement. This agreement will
terminate on December 31, 2005, unless extended or otherwise terminated. We
paid Owens Corning $1.1 million for the refurbishing of bushings during the
first quarter of 1999.

  Support Services Agreement. We entered into a support services agreement
pursuant to which Owens Corning provides engineering, design and technical
services to us at previously agreed upon prices for a five-year period. The
support services agreement will be automatically extended each year for an
additional one-year term until terminated.

  Transitional Services Agreement. We entered into a transitional services
agreement pursuant to which Owens Corning provides corporate, administrative
and information systems services to us and we provide services to Owens Corning
at mutually agreed upon prices. The provision of benefits administration and
information system services will expire on December 31, 1999. The provision of
all other services provided for in the transitional services agreement expired
on March 31, 1999.

  Manufacturing Services Agreement. We entered into a manufacturing services
agreement pursuant to which we provide manufacturing services to Owens Corning
to support their glass mat manufacturing and distribution business in
Huntingdon. Owens Corning pays an annual fee (to be mutually agreed upon and
periodically reviewed) for our provision of manufacturing, management and
ancillary services and pays additional fees in exchange for our provision of
other services that may be requested by Owens Corning. The manufacturing
services agreement will expire whenever Owens Corning or any of its affiliates
no longer owns a 49% ownership interest in us, unless earlier terminated.

Supply Agreements

  Prior to the formation transactions, Owens Corning obtained raw materials
from its affiliates or through third party suppliers. We have entered into
supply agreements, more fully described below, which provide us with access to
the necessary raw materials through Owens Corning's affiliated and non-
affiliated suppliers. In addition, pursuant to the agreements described below,
we purchased assets of the glass yarns business of several of Owens Corning's
non-U.S. affiliates. We also agreed to sell byproducts of one of its
manufacturing processes to Owens Corning.

  Byproducts Supply Agreement. We entered into a supply agreement pursuant to
which Owens Corning will purchase the first 10 million pounds of byproducts of
our manufacturing processes called dry chopped yarn and slit hanks, also known
as "sliver," that we produce each year. Each year, Owens Corning will pay a
fixed price per pound for the first 10 million pounds of byproducts and a
higher fixed price for any additional amounts shipped by us. We are under no
obligation to manufacture any specified quantity of the byproducts to supply to
Owens Corning. The byproducts supply agreement will expire on December 31,
2003, after which it may be renewed for additional five-year terms, unless
canceled by either party.

  Borates Supply Agreement. Prior to the formation transactions, Owens Corning
entered into an agreement with Etibank, a supplier of borates in Turkey that is
owned by the Turkish government, pursuant to which Etibank mines, processes,
sells and delivers borates to Owens Corning for use in manufacturing glass
yarns. We entered into a borates supply agreement pursuant to which we purchase
borates from Owens Corning at a price equal to Owens Corning's cost to
purchase, transport and process borates plus a $150,000 annual administrative
charge. The borates supply agreement will terminate on December 31, 2005, after
which it will automatically renew for a period equal to any renewal period in
Owens Corning's supply agreement with Etibank, unless canceled by either party
upon 90 days' advance notice.

  OC Belgium Agreements. We and N.V. Owens Corning S.A., a wholly owned
subsidiary of Owens Corning ("OC Belgium"), entered into a supply agreement
pursuant to which we purchase at previously determined prices fiberglass yarns
to be manufactured by OC Belgium at its facility in Battice, Belgium. We also
have the option to acquire the Battice plant's fiberglass yarns manufacturing
equipment upon the termination of the agreement or at the time Owens Corning no
longer uses this equipment to produce fiberglass yarns. The supply agreement
with OC Belgium will terminate on December 31, 2003, after which it may be
renewed for additional one-year terms, unless canceled by either party. In
addition, we have an exclusive right to terminate this agreement effective
December 31, 2001 upon one year's prior notice.

  We and OC Belgium also entered into a purchase agreement pursuant to which we
purchased OC Belgium's list of customers that purchase heavy glass yarns from
OC Belgium, transferable contracts between OC Belgium and its customers, the
finished products inventory of heavy glass yarns owned by OC Belgium that were
located in its public warehouse in Antwerp, Belgium, and all of OC Belgium's
accounts receivable arising exclusively out of the sale of heavy glass yarns by
OC Belgium.

  OC Canada Agreements. Our Canadian subsidiary and Owens-Corning Canada, Inc.,
a wholly owned subsidiary of Owens Corning ("OC Canada"), entered into a supply
agreement pursuant to which we purchase at previously determined prices minimum
and maximum quantities of fiberglass

                                       54
<PAGE>

yarns to be manufactured by OC Canada at its facility in Guelph, Canada. We
intend to append to this agreement an arrangement pursuant to which we will
purchase for distribution Low Tex Type 30 yarns manufactured by Owens Corning
at agreed upon prices. We have the option to acquire the Guelph plant
fiberglass yarns manufacturing equipment upon the termination of the agreement
or at the time Owens Corning no longer uses this equipment to produce
fiberglass yarns. The supply agreement with OC Canada will terminate on
December 31, 2001, after which it may be renewed for additional one-year terms,
unless canceled by either party. In addition, we have the exclusive right to
terminate this agreement at any time upon 90 days' prior notice.

  Our Canadian subsidiary and OC Canada also entered into a purchase agreement
pursuant to which we purchased OC Canada's list of customers which purchase
heavy glass yarns from OC Canada, transferable contracts between OC Canada and
its customers, and all of OC Canada's accounts receivable arising exclusively
out of the sale of heavy glass yarns by OC Canada.

  OC Japan Agreement. We and Owens Corning (Japan) Ltd., a wholly owned
subsidiary of Owens Corning ("OC Japan"), entered into a purchase agreement
pursuant to which we purchased OC Japan's list of customers which purchase
glass yarns from OC Japan, various transferable contracts between OC Japan, its
customers, all of OC Japan's accounts receivable arising exclusively out of the
sale of glass yarns by OC Japan, and the finished products inventory of glass
yarns owned by OC Japan that were located in its warehouses in Tokyo and Osaka,
Japan.

  Rio Claro Low Tex Type 30 Agreements. We and Owens Corning do Brazil Ltda
("OC Brazil"), a wholly owned subsidiary of Owens Corning, intend to enter into
supply agreements pursuant to which we will purchase for distribution minimum
and maximum quantities of fiberglass yarns with a bare glass linear density of
300 at agreed upon prices. These yarns are to be manufactured by OC Brazil at
its plant in Rio Claro, Brazil.

  Glass Marbles Supply Agreement. We entered into a glass marbles supply
agreement pursuant to which we purchase exclusively from Owens Corning at
mutually determined prices all of our requirements for glass marbles for use in
our glass yarns business. Owens Corning has agreed not to supply glass marbles
to any third party for use in the manufacturing of glass yarns. We have the
option to acquire Owens Corning's glass marbles manufacturing equipment upon
the termination of the agreement or at the time Owens Corning no longer uses
this equipment to produce glass marbles. The glass marbles supply agreement
will expire on December 31, 2005, after which it may be renewed for additional
five-year terms by either party, unless terminated by us upon two years' prior
notice. We purchased $1.2 million of glass marbles during the first quarter of
1999 from Owens Corning.

Co-location Arrangement with BGF Industries in South Hill, Virginia

  Prior to the formation transactions, Owens Corning entered into a co-location
arrangement with BGF Industries in South Hill, Virginia. As a result of the
formation transactions, we have succeeded to Owens Corning's rights and
obligations under the co-location arrangement. As part of the arrangement, we
lease approximately 27,200 square feet of segregated space within BGF
Industries' recently built multi-layer plant for the purpose of manufacturing
fiberglass yarn for sale to BGF Industries pursuant to a 10-year renewable
supply contract. We paid BGF Industries approximately $165,000 pursuant to this
co-location arrangement during the first quarter of 1999. Also as part of the
co-location arrangement, we lease from BGF Industries manpower at an hourly job
rate per employee

                                       55
<PAGE>

and BGF Industries provides technical, quality control and improvement and
other non-managerial services at previously determined rates. The employee
leasing and services contracts end upon the termination of either the premises
lease or the supply contract. The parties also have agreed to confidentiality
and disclosure obligations in connection with the co-location arrangement.

Intellectual Property

  In connection with the formation transactions, Owens-Corning Fiberglas
Technology, Inc., a wholly owned subsidiary of Owens Corning, assigned to us
patents, know-how, trademarks and business information, relating to or used in
our business. Owens Corning has also licensed to us additional intellectual
property assets and rights, mainly patents and know-how, pursuant to a patent
and know-how license agreement and related agreements (collectively, the
"Master License"). The Master License grants to us a worldwide, paid-up and
royalty-free license to make, have made, use, sell, import and offer to sell
glass fiber specialty products. The license is exclusive for the duration of
the non-compete agreement between Owens Corning and us with respect to various
products and non-exclusive with respect to others, and we have limited
sublicensing rights. The patent license included in the Master License is for
the life of the patent, while the know-how license is perpetual. The patent and
know-how licenses are terminable only upon the occurrence of specified events.
The Master License also includes a grant-back license pursuant to which Owens
Corning may manufacture, import and sell various yarn products under our
patents. This grant-back license does not include those products which Owens
Corning is prohibited from selling for the duration of the non-compete
agreement. The Master License further provides that Owens Corning has agreed to
render to us, upon request and on terms to be agreed upon, various services
relating to our manufacture of glass yarn products.

                       DESCRIPTION OF OTHER INDEBTEDNESS

Senior Credit Facility

  In connection with the formation transactions, we entered into a senior
credit facility pursuant to which the lenders committed to lend to Advanced
Glassfiber Yarns up to $315.0 million, with that amount allocated among:

  . a six-year revolving credit facility in an aggregate principal amount of
    up to $75.0 million (the "Revolver");

  . a six-year term loan in an aggregate principal amount of $115.0 million
    ("Term Loan A"); and

  . a seven-year term loan in an aggregate principal amount of $125.0 million
    ("Term Loan B," and together with Term Loan A, the "Term Loans").

First Union National Bank serves as agent under the senior credit facility.

  Repayment. Commitments under the Revolver will be reduced prior to maturity
on September 30, 2004, if:
  .non-ordinary course asset dispositions occur;

  .Advanced Glassfiber Yarns or any credit facility guarantor issues debt or
     equity securities; or

  . Advanced Glassfiber Yarns or any credit facility guarantor receives
    specific insurance proceeds.

  The Term Loans amortize on a quarterly basis based on the following schedule:

</TABLE>

  Advanced Glassfiber Yarns is generally required to prepay the Term Loans with
excess cash flow.

  Security; Guaranty. The senior credit facility is secured by a first priority
lien on substantially all of our properties and assets and the properties and
assets of our respective domestic subsidiaries, now owned or acquired
thereafter, and a pledge of Porcher Industries' membership interest in us. The
senior credit facility is guaranteed by AGY Capital and will be guaranteed by
all of Advanced Glassfiber Yarns' future domestic subsidiaries.

  Interest. At our option, the interest rates per annum applicable to the
Revolver, Term Loan A and Term Loan B are fluctuating rates of interest
measured by reference either to:

  . LIBOR plus a borrowing margin; or

  . First Union National Bank's base rate, which is the greater of the
    published prime rate of First Union National Bank or the overnight
    federal funds rate plus 0.5% (the "ABR") plus a borrowing margin.

The applicable borrowing margin for the Revolver and Term Loan A ranges from
1.75% to 3.0% for LIBOR-based borrowings and 0.5% to 1.75% for ABR-based
borrowings. The applicable borrowing margin for Term Loan B ranges from 3.50%
to 3.75% for LIBOR-based borrowings and 2.25% to

                                       57
<PAGE>

2.5% for ABR-based borrowings. We have entered into interest rate hedging
agreements which effectively fix the rates of interest on Term Loan A and Term
Loan B at 4.92% and 5.04% per annum, respectively, plus the applicable
borrowing margin.

  Covenants. The senior credit facility contains covenants restricting us with
respect to the following:

  . the incurrence of debt, including guarantees;

  . the creation of liens;

  . substantially changing the nature of our businesses;

  . the consummation of transactions such as dispositions of substantial
    assets, mergers, acquisitions, reorganizations and recapitalizations;

  . the making of investments and loans, non-ordinary course asset sales and
    capital expenditures;

  . the making of dividends and other distributions;

  . transactions with affiliates; and

  . our ability to prepay debt.

  The senior credit facility also requires that we comply with the following
financial tests and maintain the following financial ratios:

  . maintaining a maximum leverage ratio as of the last day of each quarter
    of the years set forth below in the corresponding amounts set forth
    below:

                                       58
<PAGE>

  The senior credit facility also contains customary events of default. An
event of default under the senior credit facility will allow the lenders
thereunder to accelerate or, in some cases, automatically cause the
acceleration of, the maturity of the debt under the senior credit facility and
will restrict our ability and the ability of the note guarantors to meet
obligations to the holders of the notes. See "Description of Exchange Notes."

Keep-Well Agreement

  In connection with the formation transactions. Owens Corning agreed to enter
into a keep-well agreement with us. Until January 14, 2002, if we do not have
the liquidity necessary to pay interest on the notes or on the senior credit
facility when due, Owens Corning will loan us an amount equal to the aggregate
deficiency. The proceeds of any loan would first be applied to interest due on
the notes and then, subject to limitations, to interest due on the senior
credit facility. As of December 31, 1998, the obligation of Owens Corning to
make loans to us under the keep-well agreement was limited to a maximum
aggregate amount of $65.0 million, and a maximum annual amount of
$20.0 million; except that the annual amount will be reduced by $10.0 million
after each interest payment date with respect to the notes. Any loans made to
us pursuant to the keep-well agreement will be subordinate to the notes and any
amounts outstanding under the senior credit facility. If we were to file for
bankruptcy protection, the keep-well agreement would probably cease to be
enforceable.

                         DESCRIPTION OF EXCHANGE NOTES

  We will issue the exchange notes under our indenture with The Bank of New
York, as trustee. The terms of the exchange notes include those stated in the
indenture and those incorporated by reference to the Trust Indenture Act of
1939.

  The following description is a summary of the material provisions of the
indenture. It does not restate the indenture in its entirety. We urge you to
read the indenture because it, and not this summary, defines your rights as
holders of the exchange notes. We have filed a copy of the indenture as an
exhibit to the registration statement which includes this prospectus.

  We will issue the exchange notes in exchange for an equal principal amount of
old notes. The exchange notes are identical in all material respects to the old
notes except that:

    (1) the exchange notes have been registered under the Securities Act; and

    (2) the registration rights and liquidated damages provisions applicable
  to the old notes are not applicable to the exchange notes.

  The exchange notes are unsecured senior subordinated obligations of ours. The
exchange notes will be unconditionally guaranteed, jointly and severally, on an
unsecured senior subordinated basis by all future direct and indirect
"Restricted Subsidiaries" other than AGY Capital and foreign subsidiaries of
Advanced Glassfiber Yarns. All of our subsidiaries are "Restricted
Subsidiaries" unless otherwise designated.


                                       59
<PAGE>

  As of the date of this prospectus:

  .there are no Restricted Subsidiaries providing note guarantees;

  .Advanced Glassfiber Yarns has one foreign subsidiary which is a Restricted
    Subsidiary; and

  .AGY Capital is also a Restricted Subsidiary.

Principal, Maturity and Interest

  The exchange notes will mature on January 15, 2009. Interest on the exchange
notes will accrue at the rate of 9 7/8% per annum. We will pay interest semi-
annually in arrears on each January 15 and July 15, commencing on July 15,
1999. We will make each interest payment to holders of record at the close of
business on the immediately preceding January 1 and July 1. Interest on the
exchange notes will accrue from the most recent date on which interest has been
paid or, if no interest has been paid, from and including January 21, 1999, the
date of issuance of the old notes. The exchange notes will not be entitled to
the benefit of any mandatory sinking fund.

Ranking

  The exchange notes rank:

    (1) junior in right of payment to all existing and future Senior
  Indebtedness;

    (2) equal in right of payment with all subordinated Senior Indebtedness;
  and

    (3) senior in right of payment to all subordinated Indebtedness.

  At March 31, 1999, we had approximately $241.6 million of Senior Indebtedness
outstanding, exclusive of unused commitments. All debt that we incur under our
senior credit facility is Senior Indebtedness of Advanced Glassfiber Yarns, is
guaranteed by all note guarantors on a senior basis and is secured by
substantially all of the assets of Advanced Glassfiber Yarns.

Note Guarantees

  If any person becomes a Restricted Subsidiary, other than foreign
subsidiaries, we will cause the Restricted Subsidiary to become a party to the
indenture and unconditionally guarantee all of our obligations under the
exchange notes. Thereafter, the Restricted Subsidiary would be a note
guarantor.

  Each note guarantor will irrevocably and unconditionally guarantee, jointly
and severally, on an unsecured senior subordinated basis, the punctual payment
of all of our obligations under the exchange notes. Each note guarantor will
agree to pay, on a senior subordinated basis and in addition to the punctual
payment of all our obligations under the exchange notes, any and all expenses,
including reasonable counsel fees and expenses, incurred by the trustee or the
holders in enforcing any rights under the note guarantee.

  The guaranteed obligations will rank:

    (1) junior in right of payment to all existing and future Senior
  Indebtedness of the note guarantors;

    (2) equal in right of payment with all subordinated Senior Indebtedness
  of the note guarantors; and

                                       60
<PAGE>

    (3) senior in right of payment to all subordinated Indebtedness of the
  note guarantors.

  All of our debt under the senior credit facility, which we discuss more fully
under "Description of Other Indebtedness" and includes any related refinancing,
will be guaranteed by each note guarantor on a senior basis and will be secured
by substantially all of the assets of each note guarantor.

  The guaranteed obligations of each note guarantor will be limited to the
maximum amount as will,

  .after giving effect to all other contingent and fixed liabilities of the
  note guarantor; and

  . after giving effect to any collections from or payments made by or on
    behalf of any other note guarantor in respect of the guaranteed
    obligations of the other note guarantor,

result in the guaranteed obligations of the note guarantor not constituting a
fraudulent conveyance or fraudulent transfer under federal, state or other
applicable law.

  Each note guarantor that makes a payment or distribution under a note
guarantee will be entitled to a contribution from the other note guarantors in
a pro rata amount, based on the net assets of each note guarantor determined in
accordance with GAAP. For further information, you should review the section
"Risk Factors" under the heading "Issuance of the old notes and any note
guarantee may be subject to fraudulent conveyance laws."

  A note guarantor will be released from its obligations under its note
guarantee in the event:

    (1) there is a defeasance of the exchange notes as described under "--
  Legal Defeasance and Covenant Defeasance";

    (2) there is a sale or other disposition of all or substantially all of
  the assets of the note guarantor in compliance with the indenture;

    (3) there is a sale or other disposition of all of the capital stock or
  other equity interests of the note guarantor in compliance with the
  indenture; or

    (4) the note guarantor is designated as an unrestricted subsidiary as
  described under "--Material Covenants--Designation of Unrestricted
  Subsidiaries."

Subordination of the Exchange Notes and the Note Guarantees

  The payment of the principal of, premium, if any, and interest on the
exchange notes is subordinated to the prior payment of all Senior Indebtedness.
In addition, the payment of the guaranteed obligations by a note guarantor
would be subordinated to the prior payment of all Senior Indebtedness of that
note guarantor to substantially the same extent as the exchange notes are
subordinated to our Senior Indebtedness. As a result, the exchange notes will
be effectively subordinated to all Senior Indebtedness of any note guarantor
and to all debt of any other subsidiaries that we may have in the future.
However, any payment made by Owens Corning under the keep-well agreement will
not be subject to these subordination provisions.

                                       61
<PAGE>

  Upon a total or partial liquidation or dissolution of us or a note guarantor,
the holders of our Senior Indebtedness or the Senior Indebtedness of a note
guarantor would be entitled to receive payment of all obligations due under
that Senior Indebtedness before the holders of exchange notes are entitled to
receive any payment. If any distribution is made to holders that, due to the
subordination provisions, should not have been made, the holders would be
required to hold it in trust for the holders of our Senior Indebtedness or the
Senior Indebtedness of the note guarantor and pay it over to them.

  In addition, neither we nor any Note Guarantor may make any payment on the
exchange notes or make any deposit as described under "--Legal Defeasance and
Covenant Defeasance" below or repurchase, redeem or otherwise retire any
exchange notes if:

    (1) any of the following designated Senior Indebtedness is not paid when
  due:

           .  the senior credit facility;

           .  up to $25.0 million of other Senior Indebtedness that is
              specifically designated as "designated Senior Indebtedness"; and

           .  any guarantee by a note guarantor that is specifically
              designated as "designated Senior Indebtedness"; or

    (2) any other default on designated Senior Indebtedness occurs, the
  maturity of that designated Senior Indebtedness is accelerated and the
  trustee receives a payment blockage notice from us or the holders of the
  designated Senior Indebtedness.

Nonetheless, we and any note guarantor may pay the exchange notes if we obtain
written notice approving the payment from the representative of the designated
Senior Indebtedness with respect to which either of these events has occurred
and is continuing.

  Payments on the exchange notes would be resumed:

    (1) in the case of a payment default, upon the date on which the default
  is cured or waived; and

    (2) in the case of a nonpayment default, the earlier of the date on which
  the nonpayment default is cured or waived or 179 days after the date on
  which the applicable payment blockage notice is received, unless the
  maturity of any designated Senior Indebtedness has been accelerated.

  No new payment blockage notice may be delivered unless and until:

    (1) 360 days have elapsed since the effectiveness of the immediately
  prior payment blockage period; and

    (2) all scheduled payments of principal, premium and interest on the
  exchange notes that have come due have been paid in full.

  We must promptly notify holders of our Senior Indebtedness if payment of the
exchange notes is accelerated because of an Event of Default.

  As a result of the subordination provisions described above, in the event of
a bankruptcy, liquidation or reorganization, you may recover less ratably than
our creditors who hold Senior

                                       62

Indebtedness. For more information, you should review the section "Risk
Factors" under the heading "Your exchange notes will be subordinate to our
senior debt."

Redemption

  Optional Redemption. We may redeem all or part of the exchange notes on and
after January 15, 2004. If we redeem the exchange notes, we must give not less
than 30 nor more than 60 days' notice. We may redeem the exchange notes at the
following redemption prices plus accrued interest, subject to the right of
holders of record on a record date to receive interest due on the related
interest payment date that is on or prior to the date of redemption. The
redemption prices are expressed as percentages of the principal amount of the
exchange notes if redeemed during the twelve-month period commencing on January
15 of the following years:

      ----                                                            ----------

      2006...........................................................  101.688
      2007 and thereafter............................................  100.000
</TABLE>

  Optional Redemption upon Public Equity Offerings. In addition, at any time on
or prior to January 15, 2002, we may use the net cash proceeds within 60 days
of a public equity offering of our qualified capital stock to redeem up to 35%
of the exchange notes. The redemption price will be equal to 110.125% of the
principal amount of the exchange notes plus accrued and unpaid interest,
subject to the right of holders of record on a record date to receive interest
due on the related interest payment date that is on or prior to the date of
redemption. At least 65% of the aggregate principal amount of the exchange
notes originally issued must remain outstanding after giving effect to this
redemption.

  If less than all of the exchange notes are to be redeemed, the trustee will
select exchange notes for redemption on a pro rata basis, by lot or by any
method that the trustee deems fair and appropriate. However, we will only
redeem exchange notes in multiples of $1,000. If we redeem exchange notes, we
must give at least 30 but not more than 60 days' notice before the redemption
date to each holder of exchange notes to be redeemed. If any exchange note is
to be redeemed in part only, the notice of redemption that relates to that
exchange note must state the portion of the principal amount of that exchange
note to be redeemed. A new exchange note in a principal amount equal to the
unredeemed portion of that exchange note will be issued in the name of the
holder upon cancellation of the original exchange note. On and after the
redemption date, interest will cease to accrue on exchange notes or portions of
exchange notes called for redemption as long as we have deposited with the
paying agent sufficient funds to pay the redemption price.

Change of Control

  Upon the occurrence of a change of control, as defined in "Material
Definitions," you would have the right to require that we purchase all or a
portion, in integral multiples of $1,000, of your notes. The purchase price
would equal 101% of the principal amount of the notes plus accrued and unpaid
interest, subject to the right of holders of record on a record date to receive
interest due on the related interest payment date that is on or prior to the
date of purchase. Within 30 days following any change of control, we will mail
a notice to each holder offering to repurchase the exchange notes.


                                       63
<PAGE>

  We will, to the extent lawful:

    (1) accept for payment all exchange notes or portions of exchange notes
  properly tendered in the change of control offer; and

    (2) deposit with the paying agent sufficient funds to pay holders of the
  tendered exchange notes.

  The senior credit facility currently contains prohibitions on the occurrence
of events that would constitute a change of control and requires that we repay
amounts outstanding under the senior credit facility upon a change of control.
Our future Senior Indebtedness could contain similar provisions. Moreover, the
exercise by the holders of their right to require us to repurchase the notes
would currently cause a default under the senior credit facility due to the
financial effect of a repurchase on us.

  If we offer to repurchase your exchange notes upon a change of control, we
cannot assure you that we will have available funds sufficient to pay the
change of control purchase price for all the tendered notes. As of March 31,
1999, we had approximately $241.6 million of Senior Indebtedness outstanding.
All of our Senior Indebtedness is outstanding under the senior credit facility.
We expect that we would seek third-party financing to the extent we do not have
available funds to meet our purchase obligations and any other obligations in
respect of Senior Indebtedness. However, we cannot assure you that we would be
able to obtain this financing.

  In addition, we would not be able to purchase any notes if we cannot obtain
the necessary consents of senior lenders and we cannot obtain the necessary
third-party financing. In this case, our failure to purchase tendered notes
would constitute an Event of Default under the indenture which may only be
waived by the holders of a majority of the notes. The Event of Default may not
be waived merely by us or the trustee.

Material Covenants

  Limitation on Incurrence of Additional Indebtedness. Neither Advanced
Glassfiber Yarns nor any of its Restricted Subsidiaries will incur any
Indebtedness other than Permitted Indebtedness, including Acquired
Indebtedness. However, Advanced Glassfiber Yarns and any note guarantor may
incur Indebtedness if our Consolidated Fixed Charge Coverage Ratio is greater
than 2.0 to 1.0 immediately before and after incurring the Indebtedness.

  Limitation on Restricted Payments. Neither Advanced Glassfiber Yarns nor any
of its Restricted Subsidiaries will:

    (1) declare or pay any dividend or make any distribution on capital stock
  or other equity interests of Advanced Glassfiber Yarns or that Restricted

    purchase or acquire shares of qualified capital stock or dividends or
    distributions to Advanced Glassfiber Yarns or a Restricted Subsidiary;
    and

    and/or its Restricted Subsidiaries and to minority holders of capital
    stock or other equity interests of Restricted Subsidiaries;

    (2) purchase, redeem or otherwise acquire or retire for value:

      (a) any capital stock or other equity interests of Advanced

    any class of that capital stock or other equity interests other than
    Permitted Investments;

    (3) make any principal payment on, purchase, defease, redeem, prepay,
  decrease or otherwise acquire or retire for value any subordinated
  Indebtedness prior to any scheduled final maturity, scheduled repayment or
  scheduled sinking fund payment; or

    (4) make any Investment other than Permitted Investments,

  if at the time of any of these "Restricted Payments":

    (1) a default or an Event of Default has occurred;

    (2) Advanced Glassfiber Yarns is not able to incur at least $1.00 of
  additional Indebtedness, other than Permitted Indebtedness, in compliance
  with the covenant described under "--Limitation on Incurrence of Additional
  Indebtedness"; or

    (3) the total amount of cash or fair market value of any other property
  comprising the Restricted Payments, including the proposed Restricted
  Payment, made subsequent to January 21, 1999 exceeds the sum of:

      (a) 50% of cumulative Consolidated Net Income, or if cumulative
    Consolidated Net Income is a loss, minus 100% of the loss, accrued
    during the period beginning on January 1, 1999 to the end of the most
    recent quarter for which consolidated financial information is
    available; plus

      (b) 100% of the total net cash proceeds received by Advanced
    Glassfiber Yarns from any person other than a Restricted Subsidiary
    from any of the following:

           . a capital contribution to Advanced Glassfiber Yarns;

           . the issuance and sale of qualified capital stock of Advanced
             Glassfiber Yarns subsequent to January 21, 1999;

           . the issuance of warrants, rights or options to purchase or
             acquire shares of capital stock or other equity interests of
             Advanced Glassfiber Yarns; or

             of Advanced Glassfiber Yarns or any Restricted Subsidiary that
             has been converted into or exchanged for qualified capital stock
             of Advanced Glassfiber Yarns; plus

      (c) in the case of the disposition or repayment of, or the receipt by
    Advanced Glassfiber Yarns or any Restricted Subsidiary of any dividends
    or distributions from, any Investment constituting a Restricted Payment
    made after January 21, 1999, an amount equal to the lesser of the
    amount of the Investment and the amount received by Advanced

                                       65
<PAGE>

    Glassfiber Yarns or any Restricted Subsidiary upon that disposition,
    repayment, dividend or distribution; plus

      (d) in the event Advanced Glassfiber Yarns or any Restricted
    Subsidiary makes any Investment in a person that, as a result of or in
    connection with that Investment, becomes a Restricted Subsidiary, an
    amount equal to Advanced Glassfiber Yarns' or any Restricted
    Subsidiary's existing Investment in that person that was previously
    treated as a Restricted Payment; plus

      (e) so long as the designation of any subsidiary as an unrestricted
    subsidiary was treated as a Restricted Payment made after January 21,
    1999, with respect to any unrestricted subsidiary that has been
    redesignated as a Restricted Subsidiary after January 21, 1999, an
    amount equal to Advanced Glassfiber Yarns' Investment in that
    unrestricted subsidiary, but the amount will not in any case exceed the
    designation amount with respect to that Restricted Subsidiary upon its
    designation; plus

      (f) $5.0 million, which amount will not be reduced by any negative
    amount that occurs under clause (a) or clause (h); minus

      (g) the designation amount with respect to any subsidiary of Advanced
    Glassfiber Yarns which has been designated as an unrestricted
    subsidiary; and minus

      (h) 50% of any distributions made to Jefferson Holdings or AGY
    Holdings.

  Nonetheless, we are not prohibited from:

    (1) paying any dividend within 60 days after the date of declaration if
  the dividend would have been permitted on the date of declaration;

    (2) if no default or Event of Default has occurred, acquiring any shares
  of capital stock or other equity interests of Advanced Glassfiber Yarns or
  any warrants, rights or options to purchase or acquire shares of capital
  stock or other equity interests of Advanced Glassfiber Yarns:

      (a) in exchange for shares of qualified capital stock of Advanced
    Glassfiber Yarns or any warrants, rights or options to purchase or
    acquire shares of qualified capital stock of Advanced Glassfiber Yarns;
    or

      (b) through the application of the net proceeds of a substantially
    concurrent sale for cash, other than to a Restricted Subsidiary, of:

           . shares of qualified capital stock of Advanced Glassfiber Yarns;
             or

           . any warrants, rights or options to purchase or acquire shares of
             qualified capital stock of Advanced Glassfiber Yarns;

    (3) if no default or Event of Default has occurred, voluntarily
  prepaying, purchasing, defeasing, redeeming or otherwise retiring any
  subordinated Indebtedness:

      (a) solely in exchange for shares of capital stock or other equity
    interests of Advanced Glassfiber Yarns or any warrants, rights or
    options to purchase or acquire shares of capital stock or other equity
    interests of Advanced Glassfiber Yarns. However, if these securities
    are convertible into or exchangeable at the option of the holder for
    Disqualified Capital Stock then the Disqualified Capital Stock must
    not:

                                       66
<PAGE>

           . mature or be mandatorily redeemable under a sinking fund
             obligation or be redeemable at the option of the holder of the
             Disqualified Capital Stock on or prior to the final maturity of
             the Indebtedness permitted to be prepaid, purchased, defeased,
             redeemed or acquired; and

           . have a weighted average life to maturity less than the
             Indebtedness permitted to be prepaid, purchased, defeased,
             redeemed or acquired; or

      (b) in exchange for refinanced Indebtedness or through the
    application of net proceeds of a substantially concurrent sale for
    cash, other than to a Restricted Subsidiary of Advanced Glassfiber
    Yarns, of:

           . shares of qualified capital stock of Advanced Glassfiber Yarns or
             any warrants, rights or options to purchase or acquire shares of
             qualified capital stock of Advanced Glassfiber Yarns; or

           . refinanced Indebtedness;

    (4) making loans or advances to officers and directors of ours or any
  Restricted Subsidiary in the ordinary course of business in an amount not
  to exceed $1.0 million at any one time outstanding;

                     (A) the maximum federal corporate income tax rate in
                   effect during that taxable year; and

                     (B) six percent; and

             (ii) the sum of ordinary income and expense and net capital gain
           allocated to Jefferson Holdings or AGY Holdings for that taxable
           year; and

             (iii) actual income taxes then being assessed against Jefferson
           Holdings or AGY Holdings on items of ordinary income and expense
           and net capital gain allocated to Jefferson Holdings or AGY

      (b) making distributions to Jefferson Holdings with respect to its
    sale of a 51% interest in Advanced Glassfiber Yarns for net asset value
    not to exceed $2.5 million; and

    (6) repurchasing, redeeming or otherwise retiring up to an annual amount
  of $750,000 of:

      (a) any capital stock or other equity interests of Advanced
    Glassfiber Yarns held by any member of our management; or

      (b) capital stock or other equity interests of Advanced Glassfiber
    Yarns held by employees, former employees, directors or former

  Limitation on Asset Sales. Advanced Glassfiber Yarns will not, and will not
permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

    (1) Advanced Glassfiber Yarns or the Restricted Subsidiary receives
  consideration at the time of the Asset Sale at least equal to the fair
  market value of the assets; and


                                       67
<PAGE>

    (2) at least 75% of the consideration received by Advanced Glassfiber
  Yarns or the Restricted Subsidiary is in the form of:

      (a) cash or cash equivalents; or

      (b) "replacement assets" such as the following:

           . long-term assets, including intellectual property associated with
             the use of those long-term assets, to be used by Advanced
             Glassfiber Yarns or any Restricted Subsidiary in a Permitted
             Business; or

           . capital stock or other equity interests of a Restricted
             Subsidiary or a person engaged primarily in a Permitted Business
             that will become a Restricted Subsidiary.

  Advanced Glassfiber Yarns or the Restricted Subsidiary may apply the net cash
proceeds of any Asset Sale generally within 270 days to any combination of the
following:

    (1) repay any Senior Indebtedness and permanently reduce those
  commitments; or

    (2) purchase replacement assets from a person other than Advanced
  Glassfiber Yarns and its Restricted Subsidiaries.

  To the extent that we do not use the net cash proceeds of any Asset Sale
within 270 days to repay Senior Indebtedness or purchase placement assets, we
will offer to repay our subordinated Senior Indebtedness, including the notes,
at a price, in the case of the notes, equal to 100% of the principal amount of
the notes to be purchased, plus accrued and unpaid interest. The interest
payment will be subject to the right of holders of record on a record date to
receive interest due on an interest payment date that is on or prior to the
date of purchase. We would make this offer within 60 days of the Asset Sale,
and repurchase any tendered notes within 20 business days of making the offer.

  We may delay an offer until there is at least $5.0 million of unapplied net
cash proceeds resulting from one or more Asset Sales.


  Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries. Advanced Glassfiber Yarns will not, and will not permit any of
its Restricted Subsidiaries to create or permit to exist any encumbrance or
restriction on the ability of any Restricted Subsidiary to:

    (1) pay dividends or make any other distributions on capital stock or
  other equity interests to Advanced Glassfiber Yarns or any other Restricted
  Subsidiary or pay any Indebtedness owed to Advanced Glassfiber Yarns or any
  other Restricted Subsidiary;

    (2) make loans or advances to, or guarantee any Indebtedness or other
  obligations of, or make any Investment in, Advanced Glassfiber Yarns or any
  other Restricted Subsidiary; or

    (3) transfer any property or assets to Advanced Glassfiber Yarns or any
  other Restricted Subsidiary, except for encumbrances or restrictions
  existing as a result of the following:

      (a) applicable law;

      (b) the indenture;

                                       68
<PAGE>

      (c) the senior credit facility or any replacement senior credit
    facility;

      (d) customary non-assignment provisions of any contract and customary
    provisions restricting assignment or subletting in any lease governing
    a leasehold interest of any Restricted Subsidiary, or any customary
    restriction on the ability of a Restricted Subsidiary to dividend,
    distribute or otherwise transfer any asset which secures Purchase Money
    Indebtedness of that Restricted Subsidiary;

      (e) any instrument governing Acquired Indebtedness, which is not
    applicable to any person, or the properties or assets of any person,
    other than the person or the properties or assets of the person so
    acquired;

      (f) restrictions with respect to a Restricted Subsidiary of Advanced
    Glassfiber Yarns imposed by a binding agreement which has been entered
    into for the sale or disposition of capital stock or other equity
    interests or assets of that Restricted Subsidiary;

      (g) customary restrictions imposed on the transfer of copyrighted or
    patented materials;

      (h) secured Indebtedness otherwise permitted to be incurred under the
    covenants described under "--Limitation on Incurrence of Additional
    Indebtedness" and""--Limitation on Liens," which is not applicable to
    any property or assets other than the property or assets subject to the
    Lien securing that Indebtedness; or

      (i) restrictions with respect to a Restricted Subsidiary that is a
    foreign subsidiary contained in any instrument governing Permitted
    Indebtedness in the form of local lines of credit not to exceed $25.0
    million in the aggregate at any one time outstanding so long as that
    Indebtedness is secured by a letter of credit issued under the senior
    credit facility.

  Limitation on the Sale or Issuance of Capital Stock of Restricted
Subsidiaries. Advanced Glassfiber Yarns will not sell or otherwise dispose of
any shares of capital stock or other equity interests of a Restricted
Subsidiary, and will not cause or permit any Restricted Subsidiary to issue or
sell or otherwise dispose of any shares of its capital stock or other equity
interests, except:

    (1) to Advanced Glassfiber Yarns or a wholly owned Restricted Subsidiary;

    (2) the sale of 100% of the shares of capital stock or other equity
  interests of any Restricted Subsidiary owned by Advanced Glassfiber Yarns
  or any Restricted Subsidiary effected in accordance with the covenants
  described under "--Limitation on Asset Sales" and "--Merger, Consolidation
  and Sale of Assets";

    (3) in the case of Restricted Subsidiaries other than wholly owned
  Restricted Subsidiaries, issuance of capital stock or other equity
  interests on a pro rata basis to Advanced Glassfiber Yarns and its
  Restricted Subsidiaries and minority shareholders of that Restricted
  Subsidiary;

    (4) the sale of capital stock or other equity interests of a Restricted
  Subsidiary or issuance by a Restricted Subsidiary of capital stock or other
  equity interests if following the sale or issuance:

      (a) the Restricted Subsidiary is no longer a subsidiary;

      (b) Advanced Glassfiber Yarns' continuing Investment in that former
    Restricted Subsidiary is in compliance with "--Limitation on Restricted
    Payments"; and

                                       69
<PAGE>

      (c) any sale of capital stock or other equity interests by Advanced
    Glassfiber Yarns or that Restricted Subsidiary complies with the
    covenant described under "--Limitation on Asset Sales."

  Designation of Unrestricted Subsidiaries. Advanced Glassfiber Yarns may
designate any subsidiary, other than AGY Capital, as an "unrestricted
subsidiary" only if:

    (1) no default or Event of Default has occurred;

    (2) we could incur $1.00 of additional Indebtedness, other than Permitted
  Indebtedness, under the covenant described under "--Limitation on
  Incurrence of Additional Indebtedness"; and

    (3) we would be permitted to make an Investment at the time of
  designation equal to the amount of Advanced Glassfiber Yarns' Investment in
  that subsidiary on that date.

  Neither Advanced Glassfiber Yarns nor any Restricted Subsidiary may:

    (1) provide credit support for, subject any property or assets other than
  the capital stock or other equity interests of any unrestricted subsidiary
  to the satisfaction of, or guarantee, any Indebtedness of any unrestricted
  subsidiary unless the credit support or guarantee constitutes an Investment
  permitted under the covenant described under "--Limitation on Restricted
  Payments";

    (2) be liable for any Indebtedness of any unrestricted subsidiary; or

    (3) be liable for any Indebtedness which provides that the holder may
  declare a default or cause the payment to be accelerated or payable prior
  to its final scheduled maturity, except for any non-recourse guarantee
  given solely to support the pledge by Advanced Glassfiber Yarns or any
  Restricted Subsidiary of the capital stock or other equity interests of any
  unrestricted subsidiary.

  Advanced Glassfiber Yarns may revoke any designation of a subsidiary as an
unrestricted subsidiary only if:

    (1) no default or Event of Default has occurred; and

    (2) all Liens and Indebtedness of the unrestricted subsidiary outstanding
  immediately following the revocation would have been permitted under the
  indenture.

  Limitation on Layered Indebtedness. Advanced Glassfiber Yarns will not, and
will not permit any Restricted Subsidiary to, incur any Indebtedness that is
subordinate in right of payment to any other Indebtedness, unless that
Indebtedness is subordinate in right of payment to, or ranks equally with, the
notes or, in the case of note guarantors, that Indebtedness is subordinate in
right of payment to, or ranks equally with, the note guarantees.

  No note guarantor will guarantee any of our Indebtedness that is subordinate
in right of payment to any of our other Indebtedness unless the guarantee is
subordinate in right of payment to, or ranks equally with, the note guarantee.

  Limitation on Liens. Except for Liens securing Senior Indebtedness and
Permitted Liens, Advanced Glassfiber Yarns will not, and will not cause or
permit any of its Restricted Subsidiaries to, incur any Liens of any kind
against any properties or assets to secure any Indebtedness unless:

                                       70
<PAGE>

    (1) in our case, we secure the notes and all other amounts due under the
  indenture; and

    (2) in the case of a note guarantor, the note guarantor secures its note
  guarantee and all other amounts due under the indenture.


  Merger, Consolidation and Sale of Assets. We will not consolidate or merge
with or into any person, whether or not we are the surviving person, or sell,
lease or otherwise dispose of, or cause or permit any Restricted Subsidiary to
sell, assign, transfer, lease, convey or otherwise dispose of all or
substantially all of our and our Restricted Subsidiaries' properties and assets
unless we satisfy the following conditions:

    (1) either:

      (a) Advanced Glassfiber Yarns is the surviving or continuing entity;
    or

      (b) the surviving person, if other than us:

           .is a corporation organized and validly existing in the United
             States; and

           .expressly assumes the due and punctual payment of the principal
             of, and premium, if any, and interest on all of the notes and the
             performance and observance of every covenant of the notes and the
             indenture and the registration rights agreement;

    (2) immediately after giving effect to the transaction:

      (a) Advanced Glassfiber Yarns or the surviving person is able to
    incur at least $1.00 of additional Indebtedness, other than Permitted
    Indebtedness, under the covenant described under "--Limitation on
    Incurrence of Additional Indebtedness"; or

      (b) the Consolidated Fixed Charge Coverage Ratio for Advanced
    Glassfiber Yarns or the surviving person would be greater than our
    Consolidated Fixed Charge Coverage Ratio immediately prior to the
    transaction;

    (3) immediately before and after giving effect to the transaction, no
  default or Event of Default has occurred;

    (4) each note guarantor, including persons which become note guarantors
  as a result of the transaction, must confirm that its note guarantee will
  apply for its obligations under the indenture and the notes; and

    (5) Advanced Glassfiber Yarns or the surviving person must deliver to the
  trustee an officers' certificate and an opinion of counsel, each stating
  that the consolidation, merger, sale, lease or other disposition complies
  with the applicable provisions of the indenture and that all conditions
  under the indenture relating to the transaction have been satisfied.

  These limitations do not apply to:

    (1) any transfer of the properties or assets of a Restricted Subsidiary
  to Advanced Glassfiber Yarns or to another Restricted Subsidiary;

    (2) any merger of a Restricted Subsidiary into Advanced Glassfiber Yarns;
  or

    (3) any merger of Advanced Glassfiber Yarns into a Restricted Subsidiary.


                                       71
<PAGE>

  Each note guarantor, unless its note guarantee is to be released, will not,
and we will not permit any note guarantor to, consolidate with or merge into
any person that is not a note guarantor unless the surviving entity assumes all
of the obligations under the note guarantee.

    Limitations on Transactions with Affiliates.  Advanced Glassfiber Yarns
  will not, and will not permit any of its Restricted Subsidiaries to, enter
  into any transaction or series of related transactions with any of our
  affiliates, unless:

      (1) the terms of the affiliate transaction are no less favorable than
    those that could reasonably be expected to be obtained in a comparable
    transaction at that time on an arm's-length basis from a person that is
    not an affiliate;

      (2) in the event that the affiliate transaction involves more than
    $5.0 million during any twelve-month period, the terms of that
    affiliate transaction are approved by a majority of the board of
    directors, including a majority of the disinterested directors; and

      (3) in the event that the affiliate transaction, other than one of
    the supply agreements described in "Related Party Transactions,"
    involves more than $10.0 million during any twelve-month period, we
    obtain a favorable opinion as to the fairness of the transaction or
    series of related transactions from a financial point of view from an
    independent financial advisor.

    However, these restrictions do not apply to:

      (1) transactions with or among Advanced Glassfiber Yarns and any
    Restricted Subsidiary or between or among Restricted Subsidiaries;

      (2) reasonable fees and compensation paid to, and any indemnity
    provided on behalf of, officers, directors, employees, consultants or
    agents of Advanced Glassfiber Yarns or any Restricted Subsidiary, as
    determined in good faith by our board of directors;

      (3) any transactions undertaken under any contractual obligations or

      (6) tax sharing or similar arrangements.

  Conduct of Business; Limitation on Activities of AGY Capital. Advanced
Glassfiber Yarns and its Restricted Subsidiaries will not engage in any
businesses other than a Permitted Business. In addition, Advanced Glassfiber
Yarns will not permit AGY Capital to acquire or hold any significant assets or
other properties or engage in any business activities.

  Reports to Holders. So long as any notes remain outstanding, we will provide
the trustee, the holders and the initial purchasers with annual reports and any
information, documents and other reports as are specified in sections 13 and
15(d) of the Exchange Act within 15 days after the times specified for the
filing. In addition, prior to effectiveness of our exchange offer registration
statement,

                                       72
<PAGE>

we will make available, upon request, to any holder and any prospective
purchaser of notes the information required in Rule 144A(d)(4) under the
Securities Act.

  Payments for Consent. Neither we nor any of our subsidiaries will pay or
cause to be paid any consideration to any holder of any notes for or as an
inducement to any consent, waiver or amendment of any terms or provisions of
the notes, unless the consideration is offered to be paid or agreed to be paid
to all holders of the notes that so consent, waive or agree to amend.

Events of Default

  The following events are "Events of Default":

    (1) the failure to pay the principal of, or premium, if any, on any note
  when due;

    (2) the failure to pay any interest on any notes when due, continued for
  30 days or more;

    (3) the failure to perform or comply with any of the provisions described
  under "--Material Covenants--Merger, Consolidation and Sale of Assets";

    (4) the failure to perform or comply with any other covenant or agreement
  contained in the indenture or in the notes which failure continues for 30
  days or more after written notice from the trustee or the holders of at
  least 25% of the notes;

    (5) the failure to pay at final maturity or upon acceleration of the
  final maturity, giving effect to any applicable grace periods and any
  extensions of the maturity, the principal amount of any Indebtedness of
  Advanced Glassfiber Yarns or any Restricted Subsidiary, if the total
  principal amount of that Indebtedness, together with the principal amount
  of any other Indebtedness in default for failure to pay principal at final
  maturity or which has been so accelerated, totals $7.5 million or more at
  any time;

    (6) one or more judgments not adequately covered by insurance in an
  amount in excess of $7.5 million have been rendered against Advanced
  Glassfiber Yarns or any of its Restricted Subsidiaries and the judgment or
  judgments remain undischarged, unpaid or unstayed for a period of 60 days
  after the judgment or judgments become final and non-appealable;

    (7) events of bankruptcy affecting us or any of Advanced Glassfiber
  Yarns' "significant" subsidiaries as defined under the Securities Act or
  group of subsidiaries that, taken together, would constitute a significant
  subsidiary; or

    (8) the note guarantee of any note guarantor is declared to be
  unenforceable in a judicial proceeding or ceases for any reason to be in
  full force and effect or any note guarantor denies or disaffirms its
  obligations under the note guarantee.

  If any of these Events of Default other than an Event of Default upon
bankruptcy occurs and is continuing, the trustee or the holders of at least 25%
of the notes may declare the principal of and premium, if any, and accrued and
unpaid interest on all the notes to be due and payable. If an Event of Default
upon bankruptcy occurs and is continuing, then all unpaid principal of, and
premium, if any, and accrued and unpaid interest on all of the notes will
automatically become immediately due and payable.


                                       73
<PAGE>

  At any time after a declaration of acceleration with respect to the notes,
the holders of a majority of the notes may rescind and cancel the declaration
and its consequences:

    (1) if all existing Events of Default have been cured or waived other
  than nonpayment of principal or interest that has become due solely because
  of the acceleration;

    (2) to the extent the payment of such interest is lawful, interest on
  overdue installments of interest and overdue principal, which has become
  due otherwise than by the declaration of acceleration, has been paid; and

    (3) if we have paid the trustee its reasonable compensation and
  reimbursed the trustee for its reasonable expenses, disbursements and
  advances.

  The holders of a majority of the notes may waive any existing default or
Event of Default under the indenture, and its consequences, except a default in
the payment of the principal of, premium, if any, or interest on any notes.

  The trustee is generally under no obligation to exercise any of its rights or
powers under the indenture at the request, order or direction of any of the
holders, unless those holders have offered to the trustee reasonable indemnity.
The holders of a majority of the notes have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
trustee or exercising any trust or power conferred on the trustee.

  No holder of any notes will have any right to institute any proceeding with
respect to the indenture unless:

    (1) that holder gives to the trustee written notice of a continuing Event
  of Default;

    (2) holders of at least 25% of the notes make a written request to pursue
  the remedy;

    (3) those holders of the notes provide to the trustee satisfactory
  indemnity;

    (4) the trustee does not comply within 60 days; and

    (5) during the 60-day period the holders of a majority of the notes do
  not give the trustee a written direction which, in the opinion of the
  trustee, is inconsistent with the request.

  Otherwise, no holder of any note will have any right to institute any
proceeding with respect to the indenture except:

    (1) a holder of a note may institute suit for enforcement of payment of
  the principal of and premium, if any, or interest on the holder's note on
  or after the due dates expressed in that note; or

    (2) the institution of any proceeding with respect to the indenture,
  including acceleration, by the holders of a majority of the notes.

  We are required to deliver to the trustee written notice of any event which
would constitute a default, its status and what action we are taking or propose
to take in respect of the default. In addition, we are required to deliver to
the trustee, within 120 days after the end of each year, a certificate
indicating whether we know of any default that occurred during the previous
year.

  If a default occurs, is continuing and is known to the trustee, the trustee
must mail to each holder notice of the default within five days after it is
known or written notice of it is received by the

                                       74
<PAGE>

trustee. Except in the case of a default in the payment of principal of,
premium, if any, or interest on any note, the trustee may withhold notice if
and so long as a committee of its trust officers in good faith determines that
withholding notice is not opposed to the interest of the holders.

Legal Defeasance and Covenant Defeasance

  We may, at our option, elect a "defeasance" which means that we would be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding notes, except for:

    (1) the rights of holders to receive payments in respect of the principal
  of, premium, if any, and interest on the notes when the payments are due;

    (2) our obligations with respect to the notes concerning issuing
  temporary notes, registration of notes, mutilated, destroyed, lost or
  stolen notes and the maintenance of an office or agency for payments;

    (3) the rights, powers, trust, duties and immunities of the trustee and
  our related obligations; and

    (4) the defeasance provisions of the indenture.

  In addition, we may, at our option, elect a "covenant defeasance" which means
we would have our obligations released with respect to some of our covenants
and thereafter any omission to comply with those obligations would not
constitute a default or Event of Default with respect to the notes. In the
event covenant defeasance occurs, some of the events described under "Events of
Default" would no longer constitute an Event of Default. Non-payment,
bankruptcy, receivership, reorganization and insolvency events, however, would
continue to be "Events of Default" with respect to the notes.

  In order to exercise either defeasance or covenant defeasance:

    (1) we must irrevocably deposit with the trustee amounts sufficient to
  pay the principal of, premium, if any, and interest on the notes;

    (2) we must deliver to the trustee an opinion of counsel to the effect
  that holders will not recognize income, gain or loss for federal income tax
  purposes as a result of the defeasance or covenant defeasance and will be
  subject to federal income tax on the same amounts, in the same manner and
  at the same times as would have been the case if the defeasance or covenant
  defeasance not occurred;


    (3) we must deliver to the trustee an officers' certificate stating that
  no default or Event of Default has occurred and is continuing on the date
  of deposit or insofar as Events of Default from bankruptcy or insolvency
  events are concerned, at any time in the period ending on the 91st day
  after the date of deposit;

    (4) we must deliver to the trustee an officers' certificate stating that
  the defeasance or covenant defeasance will not result in a breach or
  violation of, or constitute a default under, the indenture or any other
  material agreement or instrument to which we or any of our subsidiaries is
  a party or by which we or any of our subsidiaries is bound;

    (5) we must deliver to the trustee an officers' certificate stating that
  the deposit was not made by us with the intent of preferring the holders
  over any other creditors of ours or any

                                       75
<PAGE>

  subsidiary or with the intent of defeating, hindering, delaying or
  defrauding any of our other creditors or others;

    (6) we must deliver to the trustee an officers' certificate and an
  opinion of counsel, each stating that all conditions relating to the
  defeasance or the covenant defeasance have been complied with; and

    (7) we must deliver to the trustee an opinion of counsel to the effect
  that after the 91st day following the deposit, the trust funds will not be
  subject to the effect of any applicable bankruptcy, insolvency,
  reorganization or similar laws affecting creditors' rights generally.

Satisfaction and Discharge

  The indenture will be discharged and will cease to be of further effect,
except as to surviving rights or registration of transfer or exchange of the
notes, when any of the following occur:

    (1) either:

      (a) all the notes have been delivered to the trustee for
    cancellation; or

      (b) all notes not previously delivered to the trustee for
    cancellation have become due and payable, or will be due and payable
    within one year or are to be called for redemption within one year, and
    we have irrevocably deposited or caused to be deposited with the
    trustee funds sufficient to pay and discharge the notes not previously
    delivered to the trustee for cancellation;

    (2) we have paid all other sums payable under the indenture; and

    (3) we have delivered to the trustee an officers' certificate stating
  that we have complied with all conditions under the indenture relating to
  the satisfaction and discharge of the indenture.

Modification of the Indenture

  From time to time, we and the trustee, without the consent of the holders,
may amend the indenture or the notes to:

    (1) cure ambiguities, defects or inconsistencies;

    (2) provide for additional note guarantors; and

    (3) make other changes which do not, in the opinion of the trustee,
  materially adversely affect the rights of any of the holders.

  In formulating its opinion on these matters, the trustee will be entitled to
rely on evidence it deems appropriate, including solely on an opinion of
counsel. Other modifications and amendments of the indenture or the notes may
be made with the consent of the holders of a majority of the notes. However,
without the consent of the holders, no amendment may:

    (1) reduce the amount of notes whose holders must consent to an amendment
  or waiver;

    (2) reduce the rate of or change the time for payment of interest on any
  notes;

    (3) reduce the principal of or change the fixed maturity of any notes, or
  change the date on which any notes may be subject to redemption, or reduce
  the redemption price;


                                       76
<PAGE>

    (4) make any notes payable in money other than that stated in the notes;

    (5) make any change in provisions of the indenture entitling each holder
  to receive payment of principal of, premium, if any, and interest on the
  notes on or after the due date of the payment or to bring suit to enforce
  the payment, or permitting holders of a majority of notes to waive defaults
  or Events of Default;

    (6) materially amend, change or modify our obligation to make and
  consummate an offer to repurchase the notes upon a change of control that
  has occurred or make and consummate a net proceeds offer with respect to
  any Asset Sale that has been consummated;

    (7) modify the subordination provisions of the indenture with respect to
  us or any note guarantor in a manner that adversely affects the rights of
  any holder; or

    (8) eliminate or modify a note guarantor's obligations with respect to
  its note guarantee which materially adversely affects holders.

  No amendment may be made to the subordination provisions of the indenture
that adversely affects the rights of any holder of Senior Indebtedness of ours
or a note guarantor unless the holders of the Senior Indebtedness consent to
the change.

Governing Law

  The indenture and the notes are governed by, and construed in accordance
with, the laws of the State of New York but without giving effect to applicable
principles of conflicts of law to the extent that the application of the law of
another jurisdiction would be required.

The Trustee

  Except during the continuance of an Event of Default, the trustee will
perform only those duties as are specifically set forth in the indenture.
During the existence of an Event of Default, the trustee will exercise the
rights and powers vested in it by the indenture, and use the same degree of
care and skill as a prudent man would exercise or use under the circumstances
in the conduct of his own affairs.

  The indenture and the provisions of the Trust Indenture Act contain
limitations on the rights of the trustee, should it become a creditor of ours,
to obtain payments of claims or to realize on property. Subject to the Trust
Indenture Act, the trustee will be permitted to engage in other transactions.
However, if the trustee acquires any conflicting interest as described in the
Trust Indenture Act, it must eliminate the conflict or resign.

Material Definitions

  "Acquired Indebtedness" means Indebtedness with respect to any specified
person which:

    (1) exists at the time that person becomes a Restricted Subsidiary or at
  the time it merges or consolidates with Advanced Glassfiber Yarns or any of
  its Restricted Subsidiaries; or

    lesser percentage of the total voting power of Advanced Glassfiber
    Yarns than that other person;

    (3) During any period of two consecutive years or, if this event occurs
  on or before January 21, 2001, individuals who at the beginning of that
  period constituted our board of directors, together with any new directors
  whose election by the board of directors or whose nomination for election
  by our members was approved by a majority of our directors then still in
  office who were either directors at the beginning of that period or whose
  election or

                                       78
<PAGE>

  nomination for election was previously so approved, cease for any reason to
  constitute a majority of our directors then in office;

    (4) Advanced Glassfiber Yarns consolidates with, or merges with or into,
  another person, other than a wholly owned Restricted Subsidiary, or

  any wholly owned Restricted Subsidiary. This does not apply to any
  transaction where immediately after the transaction the persons that
  beneficially owned a majority of the total voting power of Advanced
  Glassfiber Yarns beneficially own a majority of the total voting power of
  the then outstanding voting stock of the surviving or transferee person;

    (5) Compagnie Saint-Gobain becomes an affiliate of Glass Holdings if that

  agreements between Owens Corning and Advanced Glassfiber Yarns; or

    (6) The non-compete agreement with Owens Corning ceases to be in full
  force and effect at any time prior to September 30, 2003.

  "Consolidated EBITDA" means Consolidated Net Income for a period, plus the
following to the extent deducted in calculating the Consolidated Net Income:

    (1) Consolidated Income Tax Expense for that period;

    (2) Consolidated Interest Expense for that period; and

      (a) all non-cash items increasing Consolidated Net Income for that
    period; and

      (b) all cash payments during that period relating to non-cash charges
    that were added back in determining Consolidated EBITDA in any prior
    period.

  "Consolidated Fixed Charge Coverage Ratio" is the ratio of the aggregate
amount of Consolidated EBITDA for the four most recent quarters to Consolidated
Fixed Charges for the four quarter period. For purposes of this definition,
"Consolidated EBITDA" and "Consolidated Fixed Charges" is calculated after
giving effect on a pro forma basis to:

    (1) the incurrence or repayment of any Indebtedness of Advanced
  Glassfiber Yarns or any of its Restricted Subsidiaries occurring during or
  after the four quarter period, as if that incurrence or repayment occurred
  on the first day of the four quarter period; and

    (2) any Investment by us in a person that becomes a Restricted
  Subsidiary, acquisition of assets not in the ordinary course of business,
  Asset Sale, other asset dispositions not in the ordinary course of
  business, or sale or disposition of capital stock occurring during or after
  the four quarter period, as if the transaction, including the incurrence of
  any Acquired Indebtedness, occurred on the first day of the four quarter
  period.

                                       79
<PAGE>

  Also, in calculating "Consolidated Fixed Charges" for purposes of determining
the denominator of this "Consolidated Fixed Charge Coverage Ratio":

    (1) interest on outstanding variable rate Indebtedness will be deemed to
  have accrued at a fixed rate per annum equal to the interest rate in effect
  on the date of determination;

    (2) if interest on any Indebtedness may optionally be determined at an
  interest rate based upon a factor of a prime or similar rate, a
  eurocurrency interbank offered rate, or other rates, then the interest rate
  in effect on the date of determination will be deemed to have been in
  effect during the four quarter period; and

    (3) interest on variable rate Indebtedness, to the extent the interest is
  covered by hedging obligations, is deemed to accrue at the rate per annum
  resulting after giving effect to the operation of the interest rate hedge
  contracts.

  For purposes of determining the Consolidated Fixed Charges Coverage Ratio at
any time prior to October 1, 1999, Consolidated EBITDA and Consolidated Fixed
Charges will be calculated as follows:

    (1) for the quarter ending December 31, 1998, Consolidated EBITDA and
  Consolidated Fixed Charges will equal Consolidated EBITDA and Consolidated
  Fixed Charges, respectively, for the quarter;

    (2) for the quarter ending March 31, 1999, Consolidated EBITDA and
  Consolidated Fixed Charges will equal Consolidated EBITDA and Consolidated
  Fixed Charges, respectively, for the two quarters then ending; and

    (3) for the quarter ending June 30, 1999, Consolidated EBITDA and
  Consolidated Fixed Charges will equal Consolidated EBITDA and Consolidated
  Fixed Charges, respectively, for the three quarters then ending.

  "Consolidated Fixed Charges" means, for any period, the sum of:

    (1) Consolidated Interest Expense; plus

    (2) the product of:

      (a) the amount of all dividend payments on any series of preferred
    stock of Advanced Glassfiber Yarns, other than dividends paid in
    qualified capital stock, paid, accrued or scheduled to be paid or
    accrued during that period, times

      (b) a fraction, the numerator of which is one and the denominator of
    which is one minus the sum of:

           .the maximum federal corporate income tax rate in effect during the
           taxable year; and

           .six percent.

  "Consolidated Income Tax Expense" means the product of:

    (1) the net income of Advanced Glassfiber Yarns and its Restricted
  Subsidiaries for that period as determined on a consolidated basis in
  accordance with GAAP; and

    (2) the sum of:

    . the maximum federal corporate income tax rate in effect during that
      period; and

    . six percent.

  would continue to have a permanent "Investment" in an unrestricted

      (a) the total amount of Advanced Glassfiber Yarns' "Investments" in
    the subsidiary made prior to or at the time of the redesignation; less

      (b) that portion of the fair market value of the net assets of the
    subsidiary at the time that the subsidiary is re-designated as a
    Restricted Subsidiary that is proportionate to Advanced Glassfiber

Yarns, Advanced Glassfiber Yarns would be deemed to have made an Investment on
the date of the sale or disposition equal to the fair market value of the
common stock of the Restricted Subsidiary not sold or disposed of.

  However, if any person other than Advanced Glassfiber Yarns or any note
  guarantor

                                       83
<PAGE>

  holds any Indebtedness or holds a Lien in respect of the Indebtedness

  Indebtedness securing Indebtedness other than Permitted Liens, that would
  constitute the incurrence of Indebtedness not constituting Permitted

    (8) Indebtedness arising from the honoring by a bank or other financial
  institution of a check, draft or similar instrument inadvertently, except
  in the case of daylight overdrafts, drawn against insufficient funds in the

  with the disposition of any business, assets, or Restricted Subsidiary,

  actually received by Advanced Glassfiber Yarns and the Restricted
  Subsidiary in connection with the disposition;

    (13) additional Indebtedness of Advanced Glassfiber Yarns or any

                    UNITED STATES FEDERAL TAX CONSIDERATIONS

  The following summary describes material U.S. federal income tax
considerations associated with the exchange of the old notes for the exchange
notes in the exchange offer and the ownership and disposition of the notes. The
summary is based on the Internal Revenue Code of 1986, as amended, and
regulations, rulings and judicial decisions as of the date of this prospectus,
all of which may be repealed, revoked or modified with possible retroactive
effect. This summary is limited to investors who will hold the notes as capital
assets within the meaning of Section 1221 of the Internal Revenue Code and does
not deal with holders that may be subject to special tax rules including, but
not limited to:

  .insurance companies;

  .tax-exempt organizations;

  .financial institutions;

  .dealers in securities or currencies;

  .traders in securities electing to mark to market;

  .holders whose functional currency is not the U.S. dollar;

  .holders who will hold the notes as a hedge against currency risks or as
    part of a straddle, synthetic security, conversion transaction or other
    integrated investment comprised of the notes and one or more other
    investments; or

  .except to the extent discussed below, Non-U.S. Holders.

The summary is applicable only to persons who tender their old notes in
exchange for newly issued exchange notes and does not address other purchasers.
This summary is for general information only and does not address all aspects
of federal income taxation that may be relevant to holders of the notes in
light of their particular circumstances. It does not address any tax
consequences arising under the laws of any state, local or foreign taxing
jurisdiction.

  You should consult your own tax advisor as to the particular tax consequences
to you of the exchange of old notes for exchange notes and the ownership and
disposition of the notes, including the applicability of any federal estate or
gift tax laws, any state, local, or foreign tax laws, any changes in applicable
tax laws, and any pending or proposed legislation or regulations. We have not
asked for or received an opinion of counsel with regard to the following
discussion of federal income tax consequences.

                                       88
<PAGE>

  As used in this prospectus, the term "U.S. Holder" means a holder of notes
that is:

  .a citizen or resident of the United States for U.S. federal income tax
    purposes;

  .a corporation or entity taxed as a corporation created or organized under
    the laws of the United States, any state in the U.S. or the District of
    Columbia;

  .an estate, the income of which is subject to United States federal income
    tax without regard to its source; or

  .a trust, if a court within the United States is able to exercise primary
    supervision over the administration of the trust and one or more United
    States persons have the authority to control all substantial decisions of
    the trust.

A "Non-U.S. Holder" is any beneficial holder that is not a U.S. Holder.

Effect of Exchange Offer

  There will be no U.S. federal income tax consequences to anyone exchanging an
old note for an exchange note in the exchange offer. You will have the same
adjusted basis and holding period in the exchange note as you had in the old
note immediately before the exchange.

U.S. Taxation of U.S. Holders

  Stated interest on notes. Stated interest on a note generally will be
included in the gross income of a U.S. Holder as ordinary income at the time it
accrues or is received in accordance with the U.S. Holder's method of
accounting for U.S. federal income tax purposes.

  Disposition of the notes. Upon the sale, exchange, redemption, retirement or
other disposition of a note, collectively, a "Disposition", a U.S. Holder
generally will recognize gain or loss equal to the difference between the
amount realized upon the Disposition, except to the extent such amount is
attributable to accrued but unpaid interest which will be taxable as such, and
such holder's adjusted tax basis in the note. A U.S. Holder's adjusted tax
basis in a note will, in general, be the U.S. Holder's cost for that note. This
gain or loss will be capital gain or loss. Net capital gain, such as capital
gain in excess of capital loss, recognized by an individual U.S. Holder upon
the disposition of a note that has been held for more than one year generally
will be subject to tax at a maximum rate of 20%. A note that has been held for
one year or less will be taxed at ordinary income tax rates. The deductibility
of capital losses is subject to limitations.

  Market discount. U.S. Holders, other than original purchasers of the old
notes, should be aware that the sale of the exchange notes may be affected by
the market discount provisions of the Internal Revenue Code. The market
discount rules generally provide that if a U.S. Holder of a note

  . purchased the note, after the original offering, at a market discount
    exceeding a statutorily defined de minimis amount, and

  . thereafter recognizes gain upon a disposition, including a partial
    redemption, of the exchange note received in exchange for an old note,

the lesser of the gain or the portion of the market discount that accrued while
the old note and exchange note were held by the U.S. Holder will be treated as
ordinary interest income at the time

                                       89
<PAGE>

of disposition. The rules also provide that a U.S. Holder who acquires a note
at a market discount may be required to defer a portion of any interest expense
that may otherwise be deductible on any indebtedness incurred or maintained to
purchase or carry the note until the U.S. Holder disposes of the note in a
taxable transaction. If a holder of a note elects to include market discount in
income currently, neither of these rules would apply.

Non-U.S. Holders

  Under present U.S. federal income tax law, subject to the discussion of
backup withholding and information reporting below:

  . payments of principal and interest on the notes to any Non-U.S. Holder
    will not be subject to U.S. federal income or withholding tax so long as:

    . the Non-U.S. Holder does not actually or constructively own 10% or
      more of the total capital or profits interests in Advanced Glassfiber
      Yarns or of the total combined voting power of all classes of stock
      entitled to vote of AGY Capital;

    . the Non-U.S. Holder is not a controlled foreign corporation that is
      related to us, directly or indirectly, through stock ownership;

    . the interest payments are not effectively connected with a United
      States trade or business; and

    . the beneficial owner of the note provides, either directly or through
      a financial institution that holds the note on behalf of the non-U.S.
      Holder and that holds customers' securities in the ordinary course of
      its trade or business, us or our agent an IRS Form W-8 or a
      substantially similar substitute form, signed under penalties of
      perjury, that it is not a United States person and provides its name
      and address; and

  . a Non-U.S. Holder will not be subject to U.S. federal income tax on gain
    realized on the sale, exchange, redemption, retirement or other
    disposition of a note, unless:

    . the gain is effectively connected with a trade or business carried on
      by the holder within the United States or, if a treaty applies,
      attributable to the United States permanent establishment maintained
      by the holder; or

    . the holder is an individual who is present in the United States for
      183 days or more in the taxable year of disposition and certain other
      requirements are met.

Backup Withholding and Information Reporting

  Backup withholding of U.S. federal income tax at a rate of 31% may apply to
payments made in respect of the notes to a holder who is not an "exempt
recipient" and who fails to provide identifying information, such as the
holder's taxpayer identification number, in the required manner. Generally,
individuals are not exempt recipients, whereas corporations and various other
entities generally are exempt recipients. Payments made in respect of notes to
a U.S. Holder must be reported to the IRS, unless the U.S. Holder is an exempt
recipient or establishes an exemption. A Non-U.S. Holder who provides an IRS
Form W-8 generally will not be subject to backup withholding.


                                       90
<PAGE>

  Upon the sale of a note to, or through, a broker, the broker must withhold
31% of the entire purchase price unless either:

  .  the broker determines that the seller is a corporation or other exempt
     recipient; or

  . the seller provides, in the required manner, identifying information and,
    in the case of a Non-U.S. Holder, certifies that the seller is a Non-U.S.
    Holder.

Such a sale must also be reported by the broker to the IRS, unless either:

  .  the broker determines that the seller is an exempt recipient; or

  .  the seller certifies that it is a Non-U.S. Holder.

  The amount of any backup withholding imposed on a payment to a holder will be
allowed as a credit against the holder's U.S. federal income tax liability and
may entitle the holder to a refund, provided that the required information is
furnished to the IRS.

                               THE EXCHANGE OFFER

Purpose and Effect

  We sold the old notes on January 21, 1999 to First Union Capital Markets
Corp. and Warburg Dillon Read LLC, which we refer to as the initial purchasers
of the old notes. The initial purchasers subsequently placed the old notes with
qualified institutional buyers in reliance upon Rule 144A under the Securities
Act. When we sold the old notes to the initial purchasers, we entered into a
registration rights agreement that required us:

  . to file a registration statement with the SEC with respect to an exchange
    offer; and

  . use our best efforts to cause the exchange offer registration statement
    to be declared effective by June 21, 1999.

  This prospectus is a part of the exchange offer registration statement that
we were required to file. As soon as the exchange offer registration statement
has been declared effective, we will offer the exchange notes in exchange for
the old notes. We will keep the exchange offer open for at least 20 business
days after the date on which notice of the exchange offer is mailed to the
holders of the old notes. For each old note validly tendered to us and not
withdrawn, the holder of the old note will receive an exchange note having a
principal amount equal to the principal amount of the surrendered old note.
Interest on the exchange notes will accrue from the last interest payment date
on which interest was paid on the old notes or, if no interest was paid on the
old notes, from January 21, 1999, the date of issuance of the old notes.

  Under existing SEC interpretations set forth in no-action letters, we believe
that the exchange notes may be offered for resale, resold and otherwise
transferred by you without compliance with the registration and prospectus
delivery provisions of the Securities Act so long as:


  . you are acquiring the exchange notes in the ordinary course of business;

  . you are not participating, do not intend to participate, and have no
    arrangement or understanding with any person to participate, in the
    distribution of the exchange notes issued to you in the exchange offer;
    and

  . you are not an affiliate of ours.

                                       91
<PAGE>

If our belief is inaccurate and you transfer any exchange notes without
delivering a prospectus meeting the requirements of the Securities Act or
without an exemption from registration of your exchange notes, you may incur
liability under the Securities Act. We do not assume or indemnify you against
this liability.

  Each participating broker-dealer that is issued exchange notes for its own
account in exchange for old notes which were acquired as a result of market-
making or other trading activities, must acknowledge that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with
any resale of the exchange notes. The accompanying letter of transmittal states
that by so acknowledging and by delivering a prospectus, the broker-dealer will
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. A participating broker-dealer may use this prospectus for an
offer to resell, resale or other retransfer of the exchange notes. We will make
this prospectus and any amendment or supplement to this prospectus available
for a period of 180 days after the date of this prospectus to any participating
broker-dealer for use in connection with any resales. We believe that no
registered holder of the old notes is an affiliate of ours as defined in Rule
405 of the Securities Act.

  By tendering your old notes, you will be representing, among other things,
that:

  . you are acquiring the exchange notes in the ordinary course of business;

  . you are not participating, do not intend to participate, and have no
    arrangement or understanding with any person to participate, in the
    distribution of the exchange notes issued to you in the exchange offer;

  . you are not an affiliate of ours; and

  . if you are a participating broker-dealer, you will deliver a prospectus
    meeting the requirements of the Securities Act in connection with any
    resale of the exchange notes.

All other broker-dealers may not rely on existing SEC interpretations set forth
in no-action letters and, absent an exemption, must comply with the
registration and prospectus delivery requirements of the Securities Act in
order to resell the old notes or the exchange notes. These requirements include
being named as a selling security holder in a registration statement related to
any resales. These broker-dealers may not use the exchange offer prospectus for
any resales.

Registration Rights

  The following is a summary of the material terms of the registration rights
agreement. A copy of the registration rights agreement has been filed as an
exhibit to the registration statement of which this prospectus is a part.

  Under the registration rights agreement, we are obligated to file a "shelf"
registration statement  covering resales of the old notes or the exchange notes
if any of the following situations occur:

  . new interpretations of the SEC prohibit us from effecting the exchange
    offer;

  . the exchange offer is not consummated within 30 business days of the date
    the exchange offer registration statement became effective;

  . an initial purchaser so requests with respect to old notes it acquired
    directly from us on or prior to the 20th business day following the
    consummation of the exchange offer;

                                       92
<PAGE>

  . any holder notifies us on or prior to the 20th business day following the
    consummation of the exchange offer that the holder is not eligible to
    participate in the exchange offer or the exchange notes the holder would
    receive would not be freely tradable; or

  . an initial purchaser participates in the exchange offer and does not
    receive freely tradable exchange notes in exchange for old notes
    constituting any portion of an unsold allotment and the initial purchaser
    notifies us on or prior to the 20th business day following the
    consummation of the exchange offer.

  If any of the events in the preceding paragraph occur, we will file a shelf
registration statement within 75 days. We will also use our reasonable efforts
to cause the shelf registration statement to be declared effective within 135
days. We will keep the shelf registration statement effective until the earlier
of:

  . the time when the old notes or the exchange notes covered by the shelf
    registration statement can be sold pursuant to Rule 144 without any
    limitations under clauses (c), (e), (f) and (h) of Rule 144;

  . two years from the date on which the shelf registration statement was
    filed; and

  . the date as of which all old notes and exchange notes covered by the
    shelf registration statement have been sold.

   If a shelf registration statement is filed, we will provide to each holder
for whom the shelf registration statement was filed copies of the prospectus
which is a part of the shelf registration statement, notify each holder when
the shelf registration statement has become effective and take other actions as
are required to permit unrestricted resales of the old notes or the exchange
notes. A holder selling old notes or exchange notes pursuant to the shelf
registration statement generally would be required to be named as a selling
security holder in the related prospectus and to deliver a prospectus to
purchasers. These holders would also be subject to the civil liability
provisions under the Securities Act and would be bound by the indemnification
provisions of the registration rights agreement.

  If any of the following "registration defaults" occur:

  . we fail to file any of the registration statements required by the
    registration rights agreement on or before the date specified for those
    filings;

  . any of the registration statements is not declared effective by the SEC
    on or prior to the date specified for effectiveness;

  . we fail to consummate the exchange offer within 30 business days of the
    date specified for effectiveness of the exchange offer registration
    statement;

  . the shelf registration statement or the exchange offer registration
    statement has been declared effective but the SEC issues a stop order
    suspending such effectiveness or proceedings have been initiated under
    Sections 8(d) or 8(e) of the Securities Act with respect to the exchange
    offer registration statement or shelf registration statement;

  . the aggregate number of days in any suspension period referred to in the
    preceding bullet point exceeds the number permitted in the registration
    rights agreement; or

  . the number of suspension periods referred to in the second preceding
    bullet point exceeds the number permitted in the registration rights
    agreement,

then we will pay liquidated damages to each holder of old notes. During the
first 90-day period immediately following the occurrence of a registration
default, we will pay liquidated damages in an

                                       93
<PAGE>

amount equal to $0.05 per week per $1,000 principal amount of old notes
outstanding. The amount of the liquidated damages will increase by an
additional $0.05 per week per $1,000 principal amount of old notes for each
subsequent 90-day period until the registration default has been cured, up to
an aggregate maximum amount of liquidated damages of $0.30 per week per $1,000
principal amount of old notes for all registration defaults. We will pay all
accrued liquidated damages on each date that interest must be paid on the old
notes. Following the cure of all registration defaults, the accrual of
liquidated damages will cease and all accrued and unpaid liquidated damages
will be paid promptly thereafter. At all other times, the old notes will bear
interest at the original interest rate.

Terms of the Exchange Offer

  Subject to the conditions in this prospectus and in the letter of
transmittal, we will accept old notes validly tendered and not withdrawn prior
to 5:00 p.m., New York City time, on the expiration date. We will issue $1,000
principal amount of exchange notes in exchange for each $1,000 principal amount
of outstanding old notes accepted in the exchange offer. You may tender some or
all of your old notes pursuant to the exchange offer. However, tenders of old
notes must be in a minimum principal amount of $1,000 or an integral multiple
of $1,000.

  The form and terms of the exchange notes will be identical in all material
respects to the form and terms of the old notes, except that:

  . the exchange notes will bear a different CUSIP number from the old notes;

  . the issuance of the exchange notes will be registered under the
    Securities Act and, therefore, the exchange notes will not bear legends
    restricting transfer; and

  . the holders of the exchange notes will not be entitled to rights under
    the registration rights agreement, including liquidated damages.

  As of the date of this prospectus, $150,000,000 aggregate principal amount of
old notes were outstanding. This prospectus and the letter of transmittal are
being mailed to persons who were holders of old notes on the close of business
on the date of this prospectus. Holders of old notes do not have any appraisal
or dissenters' rights under the Delaware Limited Liability Company Act or the
Delaware General Corporation Law or the indenture in connection with the
exchange offer. We intend to conduct the exchange offer in accordance with the
applicable requirements of the Securities Act, the Exchange Act and the rules
and regulations promulgated thereunder.

  We will be deemed to have accepted validly tendered old notes when we have
given written notice thereof to The Bank of New York, as exchange agent. The
exchange agent will act as agent for the tendering holders for the purpose of
receiving the exchange notes from us.

  If any tendered old notes are not accepted for exchange for any reason, the
certificates for the unaccepted old notes will be returned, without expense, to
the tendering holders, as soon as possible after the expiration date.

  Holders who tender old notes in the exchange offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the letter
of transmittal, transfer taxes with respect to the exchange of old notes for
exchange notes. We will pay all charges and expenses, other than transfer
taxes, in connection with the exchange offer. See "--Fees and Expenses."

Expiration Date; Extensions; Amendments

  The term "expiration date" means 5:00 p.m., New York City time, on      ,
1999, unless we extend the exchange offer, in which case the term "expiration
date" means the latest date and time to which the exchange offer is extended.

  In order to extend the exchange offer, we will notify the exchange agent by
written notice and will make a public announcement of the extension, each prior
to 9:00 a.m., New York City time, on the next business day after the previously
scheduled expiration date.

  We reserve the right, in our sole discretion:

  . to delay accepting any old notes, to extend the exchange offer or to
    terminate the exchange offer if any of the conditions set forth below
    under "--Conditions" have not been satisfied, by giving written notice of
    the delay, extension or termination to the exchange agent; or

  . to amend the terms of the exchange offer in any manner, whether before or
    after any tender of the old notes.

Any delay in acceptance, extension, termination or amendment will be followed
as soon as possible by oral or written notice to the registered holders.

Accrued Interest on the Exchange Notes

  Interest on the exchange notes will accrue from the last interest payment
date on which interest was paid on the old notes, or, if no interest was paid
on the old notes, from January 21, 1999, the date of issuance of the old notes.
Holders whose old notes are accepted for exchange will be deemed to have waived
the right to receive any interest accrued on the old notes.

Procedures for Tendering Old Notes

  Only a holder of old notes may tender old notes in the exchange offer. Each
holder wishing to accept the exchange offer must:

  .  complete, sign and date the accompanying letter of transmittal, or a
    facsimile thereof, in accordance with the instructions in this prospectus
    and the letter of transmittal;

  . have the signatures thereon guaranteed if required by the letter of
    transmittal or transmit an agent's message in connection with a book-
    entry transfer; and

  . mail or otherwise deliver the letter of transmittal or facsimile or
    agent's message, together with the old notes and any other required
    documents, to the exchange agent prior to 5:00 p.m., New York City time,
    on the expiration date.
Delivery of the old notes may be made by book-entry transfer in accordance with
the procedures described below. Confirmation of book-entry transfer must be
received by the exchange agent prior to the expiration date.

  The term "agent's message" means a message transmitted by a book-entry
transfer facility to, and received by, the exchange agent forming a part of a
confirmation of a book-entry, which states that the book-entry transfer
facility has received an express acknowledgment from the participant in the
book-entry transfer facility tendering the old notes that the participant has
received and agrees:

  . to participate in the Automated Tender Option Program;


                                       95
<PAGE>

  . to be bound by the terms of the letter of transmittal; and

  . that we may enforce such agreement against the participant.

  By executing the letter of transmittal, each holder will make the
representations set forth under the heading "--Purpose and Effect" to us. Your
tender and our acceptance will constitute an agreement that you will
participate in the exchange offer in accordance with the terms and subject to
the conditions set forth in this prospectus and in the letter of transmittal.

  The method of delivery of the old notes and the letter of transmittal and all
other required documents to the exchange agent is at your election and sole
risk. As an alternative to delivery by mail, you may wish to consider overnight
or hand delivery service. In all cases, you should allow sufficient time to
assure delivery to the exchange agent before the expiration date. You may
request your broker, dealer, commercial bank, trust company or nominee to
effect the exchange of old notes for you.

  If you are a beneficial owner whose old notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and you wish to
tender your old notes in the exchange offer, you should contact the registered
holder promptly and instruct the registered holder to tender on your behalf.

  Signatures on a letter of transmittal or a notice of withdrawal must be
guaranteed by an "eligible institution." An eligible institution is a member of
a registered national securities exchange or of the National Association of
Securities Dealers, Inc., a savings institution, commercial bank or trust
company having an office or correspondent in the United States, or otherwise an
"eligible guarantor institution" within the meaning of Rule 17Ad-15 under the
Exchange Act. These eligible institutions must each be a member of a recognized
signature guarantee program, such as the Securities Transfer Agents Medallion
Program, Stock Exchange Medallion Program or New York Stock Exchange Medallion
Signature Program. However, signatures on a letter of transmittal or notice of
withdrawal are not required to be guaranteed with respect to old notes that are
tendered:

  . by a registered holder who has not completed the box entitled "Special
    Issuance Instructions" or the box entitled "Special Delivery
    Instructions" on the letter of transmittal; or

  . for the account of an eligible institution.

  If a letter of transmittal is signed by a person other than the registered
holder, the old notes must be endorsed or accompanied by a properly completed
bond power, signed by the registered holder with the signature thereon
guaranteed by an eligible institution.

  If the letter of transmittal or any old notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, offices of
corporations or others acting in a fiduciary or representative capacity, these
persons should so indicate when signing, and evidence satisfactory to us of
their authority to so act must be submitted with the letter of transmittal.

  We understand that the exchange agent will make a request soon after the date
of this prospectus to establish an account through the facilities of The
Depository Trust Company ("DTC")

                                       96
<PAGE>

for receipt of the tender of old notes through book-entry delivery. For the
purpose of facilitating the exchange offer, any financial institution that is a
DTC participant may participate in the exchange offer through book-entry
delivery of old notes by causing DTC to transfer the old notes into the
exchange agent's account for the old notes. Although delivery of the old notes
may be effected through book-entry transfer into the exchange agent's account
at DTC, unless an agent's message is received by the exchange agent in
compliance with the Automated Tender Option Program, an appropriate letter of
transmittal properly completed and duly executed with any required signature
guarantee and all other required documents must in each case be delivered to
the exchange agent on or prior to the expiration date, or, if the guaranteed
delivery procedures described below are complied with, within the time period
provided under the procedures. Delivery of documents to DTC does not constitute
delivery to the exchange agent.

  All questions as to the validity, form, eligibility, including time of
receipt, acceptance of tendered old notes and withdrawal of tendered old notes
will be determined by us. We reserve the absolute right to reject old notes not
properly tendered or any old notes that our counsel deems would be unlawful for
us to accept. We also reserve the right to waive any defects, irregularities or
conditions of tender as to particular old notes. Our interpretation of the
terms and conditions of the exchange offer, including the instructions in the
letter of transmittal, will be final and binding on all parties. Unless waived,
any defects or irregularities in connection with tenders of old notes must be
cured within the time as we determine. Although we intend to notify holders of
defects or irregularities with respect to tenders of old notes, neither we, the
exchange agent nor any other person will incur any liability for failure to
give notification. Tenders of old notes will not be deemed to have been made
until defects or irregularities have been cured or waived. Any old notes
received by the exchange agent that are not properly tendered and as to which
the defects or irregularities have not been cured or waived will be returned by
the exchange agent to the tendering holders, unless otherwise provided in the
letter of transmittal, soon after the expiration date.

  No letter of transmittal, old notes, notice of guaranteed delivery or other
documents should be sent to us or DTC. Delivery of these documents to us or DTC
will not constitute valid delivery.

Guaranteed Delivery Procedures

  Holders of old notes who wish to tender their old notes but who cannot, prior
to 5:00 p.m., New York City time, on the expiration date:

  . deliver their old notes, the letter of transmittal or any other documents
    required by the letter of transmittal to the exchange agent; or

  . deliver a confirmation of the book-entry tender of their old notes into
    the exchange agent's account at DTC and otherwise complete the procedures
    for book-entry transfer,

may effect a tender of old notes if:

  .the tender is made through an eligible institution;

  . prior to 5:00 p.m., New York City time, on the expiration date, the
    exchange agent receives from the eligible institution a properly
    completed and duly executed notice of guaranteed delivery setting forth
    the name and address of the holder, the certificate number(s) and the
    principal amount of old notes tendered, stating that the tender is being
    made thereby and guaranteeing that, within three business days after the
    expiration date, the letter of transmittal,

                                       97
<PAGE>

   together with the certificate(s) representing the old notes, or a
   confirmation of book-entry transfer of the old notes into the exchange
   agent's account at DTC, and any other documents required by the letter of
   transmittal will be deposited by the eligible institution with the
   exchange agent; and

  . the properly completed and duly executed letter of transmittal, as well
    as the certificate(s) representing all tendered old notes in proper form
    for transfer, or a confirmation of book-entry transfer of the old notes
    into the exchange agent's account at DTC, and all other documents
    required by the letter of transmittal are received by the exchange agent
    within three business days after the expiration date.

Acceptance of Old Notes for Exchange; Delivery of Exchange Notes

  Promptly after satisfaction or waiver of all of the conditions to the
exchange offer, we will accept all old notes properly tendered and will issue
the exchange notes. For a description of conditions to the exchange offer, see
"--Conditions" below. We will be deemed to have accepted properly tendered old
notes for exchange when, as and if we have given written notice to the exchange
agent. For each old note accepted for exchange, the holder of such old note
will receive an exchange note having a principal amount equal to that of the
surrendered old note.

  In all cases, issuance of exchange notes will be made only after timely
receipt by the exchange agent of certificates for old notes or a timely
confirmation that old notes have been transferred into the exchange agent's
account at DTC, a properly completed and duly executed letter of transmittal
and all other required documents. If any tendered old notes are not accepted
for any reason, or if old notes are submitted for a greater principal amount
than the holder desires to exchange, the unaccepted or non-exchanged old notes
will be returned without expense to the tendering holder soon after the
expiration or termination of the exchange offer.

Withdrawal of Tenders

  Except as otherwise provided in this prospectus, you may withdraw a tender of
old notes at any time prior to 5:00 p.m., New York City time, on the expiration
date.

  To withdraw a tender of old notes, the exchange agent must receive a
telegram, telex, letter or facsimile transmission notice of withdrawal prior to
5:00 p.m., New York City time, on the expiration date. A notice of withdrawal
must:

  . specify the name of the person having deposited the old notes to be
    withdrawn;

  . identify the old notes to be withdrawn, including the certificate
    number(s) and principal amount of the old notes, or, in the case of old
    notes tendered by book-entry transfer into the exchange agent's account
    at DTC pursuant to the applicable book-entry procedures, the name and
    number of the account at DTC to be credited;

  . be signed by the holder in the same manner as the original signature on
    the letter of transmittal by which the old notes were tendered, including
    any required signature guarantees, or be accompanied by documents of
    transfer sufficient to have the trustee register the transfer of the old
    notes into the name of the person withdrawing the tender; and

  . specify the name in which the old notes are to be registered, if
    different from that of the depositor.

                                       98
<PAGE>

  We will determine all questions as to the validity, form and eligibility,
including time of receipt, of withdrawal notices. Any old notes so withdrawn
will be deemed not to have been validly tendered and no exchange notes will be
issued unless the old notes so withdrawn are validly retendered. Any old notes
which have been tendered but which are not accepted for exchange will be
returned, without expense, to the holder soon after withdrawal, rejection of
tender or termination of the exchange offer. Properly withdrawn old notes may
be retendered by following one of the procedures described above under "--
Procedures for Tendering Old Notes" at any time prior to the expiration date.

Conditions

  Notwithstanding any other term of the exchange offer, we are not required to
accept for exchange any old notes, and may terminate or amend the exchange
offer, if:

  . any action or proceeding is instituted or threatened in any court or by
    any governmental or quasi-governmental agency which might materially
    impair our ability to proceed with the exchange offer or any material
    adverse development has occurred in any existing action or proceeding
    with respect to us;

  . the exchange offer violates applicable law or any applicable SEC
    interpretations; or

  . any governmental or quasi-governmental approval has not been obtained,
    which approval we deem necessary for the consummation of the exchange
    offer.

  If we determine in our sole, reasonable discretion that any of the foregoing
conditions are not satisfied, we may:

  . refuse to accept any old notes and return all tendered old notes to the
    tendering holders;

  . extend the exchange offer and retain all old notes tendered prior to the
    expiration of the exchange offer, subject, however, to the rights of
    holders to withdraw such old notes in accordance with "--Withdrawal of
    Tenders"; or

  . waive the unsatisfied conditions and accept all properly tendered old
    notes which have not been withdrawn.

In addition, we reserve the right, notwithstanding the satisfaction or failure
of any or all of the conditions, to terminate or amend the exchange offer in
any manner.

  The exchange offer is not conditioned upon any minimum aggregate principal
amount of old notes being tendered or accepted for exchange.

Exchange Agent

  The Bank of New York, which also acts as trustee under the indenture, has
been appointed as exchange agent for the exchange offer. Each holder wishing to
accept the exchange offer must deliver:

  . a letter of transmittal, the holder's tendered old notes and all other
    required documents; or


                                       99
<PAGE>

  . a notice of guaranteed delivery and all other documents described under
    "--Guaranteed Delivery Procedures," to the exchange agent as follows:

By Mail or Hand Delivery:    The Bank of New York
                             101 Barclay Street
                             New York, New York 10286
                             Attention: Reorganization Section 7-E

Facsimile Transmission:      (212) 815-6339
Confirm by Telephone:        (212) 815-3502

  Delivery to an address other than as set forth above will not constitute
valid delivery.

  If you have any questions or need additional copies of this prospectus, the
letter of transmittal or the notice of guaranteed delivery, please write or
telephone the exchange agent.

Fees and Expenses

  The principal solicitation of tenders for the exchange offer is being made by
mail; however, additional solicitations may be made by telegraph, telecopy,
telephone or in person by our officers, employees or agents and our affiliates.
We have not retained any dealer-manager in connection with the exchange offer
and will not make any payments to brokers, dealers or others to solicit
acceptances of the exchange offer. We, however, will pay the exchange agent
reasonable and customary fees for its services and will reimburse it for its
reasonable out-of-pocket expenses in connection with the exchange offer. We
will pay all other expenses to be incurred in connection with the exchange
offer. These expenses include fees and expenses of the trustee, accounting and
legal fees and printing costs, among others.

Accounting Treatment

  The exchange notes will be recorded at the same carrying value as the old
notes, which is face value, as reflected in our accounting records on the date
of exchange. Accordingly, we will not recognize any gain or loss for accounting
purposes in connection with the exchange offer. The expenses of the exchange
offer will be amortized over the term of the exchange notes.

Consequences of Failure to Exchange

  The old notes that are not exchanged for exchange notes will remain
restricted securities. Accordingly, old notes may not be reoffered, resold,
pledged or otherwise transferred except in accordance with applicable state
securities laws and:

  . to a person whom the transferor reasonably believes is a qualified
    institutional buyer in a transaction meeting the requirements of Rule
    144A;

  . in an offshore transaction meeting the requirements of Rule 903 or Rule
    904 of Regulation S;

  . to an institution that is an "accredited investor" within the meaning of
    Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act;

  . under an exemption from registration under the Securities Act provided by

  Following consummation of the exchange offer, holders of the old notes who
were eligible to participate in the exchange offer but who did not tender their
old notes will generally not have any further registration rights under the
registration rights agreement, and the old notes will continue to be subject to
restrictions on transfer. Accordingly, the liquidity of the market for the old
notes could be adversely affected. See "Risk Factors--Old notes outstanding
after the exchange offer will not have registration rights and we expect the
market for the old notes to be illiquid."

                              PLAN OF DISTRIBUTION

  Except as provided herein, this prospectus may not be used for an offer to
resell, a resale or other transfer of exchange notes. Under existing SEC
interpretations set forth in no-action letters, we believe that the exchange
notes may be offered for resale, resold and otherwise transferred, other than
by our affiliates within the meaning of Rule 405 under the Securities Act,
without further compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that the exchange notes are acquired
in the ordinary course of business and the holders have no arrangement or
understanding with any person to participate in the distribution of the
exchange notes. Any holder who is one of our affiliates or who intends to
participate in the exchange offer for the purpose of distributing the exchange
notes:

  . will not be able to rely on the existing SEC interpretations set forth in
    no-action letters;

  . will not be able to tender its old notes; and

  . must comply with the registration and prospectus delivery requirements of
    the Securities Act in connection with any sale or transfer transaction
    unless the sale or transfer is made pursuant to an exemption from the
    requirements.

  A participating broker-dealer holding old notes may participate in the
exchange offer provided that it acquired the old notes for its own account as a
result of market-making or other trading activities. In connection with any
resales of exchange notes, any participating broker-dealer who receives
exchange notes in the exchange offer may be an "underwriter," within the
meaning of the Securities Act, and must deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of the
exchange notes. The SEC has taken the position that participating broker-
dealers may fulfill their prospectus delivery requirements with respect to the
exchange notes, other than a resale of an unsold allotment from the original
sale of the old notes, with this prospectus, as amended or supplemented from
time to time. Under the registration rights agreement, we are required to allow
participating broker-dealers to use this prospectus, as amended or supplemented
from time to time, in connection with the resale of exchange notes for a period
of 180 days. Each participating broker-dealer wishing to accept the exchange
offer must represent that it will deliver a prospectus meeting the requirements
of the Securities Act if it resells any exchange notes.

  All other broker-dealers may not rely on existing SEC interpretations set
forth in no-action letters and, absent an exemption, must comply with the
registration and prospectus delivery requirements of the Securities Act in
order to resell the old notes or the exchange notes. These requirements include
being named as a selling security holder in a registration statement related to
resales. These broker-dealers may not use the exchange offer prospectus for any
resales.

  The exchange offer is intended to satisfy our obligations under the
registration rights agreement. We will not receive any cash proceeds from the
issuance of the exchange notes. In consideration for

                                      101
<PAGE>

issuing the exchange notes, we will receive a like principal amount of old
notes. The form and terms of the exchange notes will be identical in all
material respects to the form and terms of the old notes, except for the
elimination of transfer restrictions, registration rights and liquidated
damages provisions relating to the old notes.

  Exchange notes received by broker-dealers for their own account in the
exchange offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the exchange notes or a combination of these methods of resale, at
market prices prevailing at the time of resale, or at prices related to
prevailing market prices or at negotiated prices. Any resale may be made
directly to purchasers or to or through broker-dealers who may receive
compensation in the form of commissions or concessions from the broker-dealer
and/or the purchasers of the exchange notes. Any broker-dealer that resells
exchange notes that were received by it for its own account in the exchange
offer and any person that participates in the distribution of exchange notes
may be deemed an "underwriter" within the meaning of the Securities Act. Any
profit on the resale and any commissions or concessions received by any such
broker-dealers may be deemed to be underwriting compensation under the
Securities Act. The letter of transmittal states that any acknowledgment by a
participating broker-dealer that it will deliver a prospectus in connection
with any resale of exchange notes, and any delivery of a prospectus, will not
be deemed an admission by the participating broker-dealer that it is an
underwriter.

  For a period of 180 days after the expiration date, we will send additional
copies of this prospectus and any amendment or supplement to this prospectus to
any participating broker-dealer that requests these documents in the
participating broker-dealer's letter of transmittal. By acceptance of the
exchange offer, each broker-dealer that receives exchange notes for old notes
agrees that, upon receipt of notice from us of the happening of any event which
makes any statement in this prospectus untrue in any material respect or which
requires the making of any changes in this prospectus in order to make the
statements herein not materially misleading, which notice we have agreed to
deliver to each broker-dealer, the broker-dealer will suspend the use of this
prospectus until we have amended or supplemented this prospectus to correct the
misstatement or omission and have furnished copies of the amended or
supplemented prospectus to the broker-dealer.

  We have agreed, pursuant to the registration rights agreement, to pay all
expenses incident to our performance of the exchange offer and the registration
rights agreement, other than agency fees and commissions, underwriting
discounts and commissions and the fees and disbursements of counsel and other
advisors and experts retained by the holders. In addition, we have agreed to
indemnify the holders of the exchange notes against liabilities under the
Securities Act.

  The exchange notes are a new issuance of securities for which there is
currently no trading market. The exchange notes will not be listed on any
national securities exchange or Nasdaq. We have been advised by the initial
purchasers that they intend to make a market in the exchange notes; however,
the initial purchasers are not obligated to do so, and any market making
activities may be discontinued at any time without notice. Accordingly, we
cannot assure you that an active trading market for the exchange notes will
develop or as to the liquidity of a market. In addition, if the exchange notes
are traded after their initial issuance, they may trade at a discount from
their initial offering price, depending upon prevailing interest rates, the
market for similar securities, our performance and other factors.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors
 Advanced Glassfiber Yarns LLC

  We have audited the accompanying consolidated balance sheet of Advanced
Glassfiber Yarns LLC and subsidiaries ("AGY" or "the Company") as of December
31, 1998 and the related statements of operations, comprehensive income and
cash flows for the period from October 1, 1998 to December 31, 1998. We have
also audited the statements of operations, comprehensive income and cash flows
of the Predecessor Business (as described in Note 1) for the period from
January 1, 1998 to September 30, 1998. These financial statements are the
responsibility of the Company's and the Predecessor Business' management,
respectively. Our responsibility is to express an opinion on these financial
statements based on our audits.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

  The financial statements for the periods ended prior to October 1, 1998, do
not reflect the new basis of accounting established by the acquisition of the
51% interest in the Predecessor Business as described in Note 1, and are
presented on the historical cost basis existing prior to the acquisition
period.

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of AGY as of December 31, 1998
and results of their operations and their cash flows for the period from
October 1, 1998 to December 31, 1998 and the results of operations and cash
flows of the Predecessor Business for the period from January 1, 1998 to
September 30, 1998 in conformity with generally accepted accounting principles.

CORNING, a Delaware corporation as described in Note 1, as of December 31, 1997

for each of the two years in the period ended December 31, 1997. These

                         NOTES TO FINANCIAL STATEMENTS


1. Basis of Presentation

  Advanced Glassfiber Yarns LLC ("AGY" or the "Company") was formed by Owens
Corning to own and operate Owens Corning's glass yarns and specialty materials
business (the "Predecessor Business" or the "Company"), which was contributed
to AGY on July 1, 1998, then, a wholly owned subsidiary of Owens Corning (the
"Contribution"). On September 30, 1998, Owens Corning sold a 51% interest in
AGY to a wholly owned subsidiary of Porcher Industries, S.A. ("Porcher
Industries") for aggregate consideration of $338.9 million (the "Majority
Purchase"). In addition, Porcher Industries paid fees and expenses of
approximately $3.2 million in connection with the Majority Purchase. Therefore,
the total aggregate consideration paid by Porcher Industries for its 51%
interest in AGY was $342.1 million. Owens Corning retained a 49% interest in
AGY.

  Prior to October 1, 1998 the Predecessor Business was managed as an operating
unit of the Composites Systems Business of Owens Corning which has provided it
with certain administrative and operational support. The accompanying financial
statements prior to the Majority Purchase include the cost of the Predecessor
Business' employees and allocations of certain corporate services provided by
Owens Corning. Management, using its experience with the Predecessor Business
and its judgment, has allocated approximately $6.2 million, $7.8 million and
$7.3 million of such corporate services and other support to the Predecessor
Business for the nine months ended September 30, 1998 and for the years ended
1997 and 1996, respectively. The allocations were made primarily by estimating
the proportional historical cost of various corporate departments and other
functions providing services to the Predecessor Business. The proportions were
based primarily upon estimates of the number of full time equivalent employees
rendering service to the Predecessor Business. Management believes that its
methodology is reasonable and that the costs of the operational and
administrative support included in the accompanying financial statements prior
to the Majority Purchase are comparable to those that the Predecessor Business
would have incurred had it operated as a separate entity. The financial
information presented herein may not necessarily reflect the financial position
and results of operations of the Predecessor Business in the future.

  Concurrently with the Majority Purchase, AGY was recapitalized. AGY borrowed
an aggregate of $404.0 million through a combination of $254.0 million under a
Senior Credit Facility (as defined herein) and the $150.0 million under a
Senior Subordinated Credit Facility (the "Subordinated Facility"). AGY used the
proceeds from the initial borrowings under the Senior Credit Facility and
Subordinated Facility plus a $2.2 million contribution from Owens Corning to
pay (i) an aggregate cash distribution of $399.2 million (the "Distribution")
to Owens Corning and Porcher Industries in the amounts of $195.6 million and
$203.6 million, respectively, and (ii) approximately $7.0 million in fees and
expenses. The initial borrowings under the Senior Credit Facility and the
Subordinated Facility, and the application of the net proceeds therefrom, are
collectively referred to as the "Financings". The Financings, together with the
Contribution and Majority Purchase are collectively referred to as the
"Formation Transactions."

  In connection with the Formation Transactions, the net cash outlay by Porcher
Industries was $138.5 million, represented by the $338.9 million paid for the
Majority Purchase plus fees and

expenses of $3.2 million less the $203.6 million cash distribution Porcher
Industries received from AGY. The total cash consideration received by Owens
Corning was $532.3 million, comprised of the $338.9 million paid by Porcher
Industries and the $195.6 million cash distribution received from AGY less a
$2.2 million contribution.

  The acquisition of the 51% interest in AGY by a wholly owned subsidiary of
Porcher Industries was accounted for as a partial purchase business combination
in accordance with the provisions of APB No. 16 "Business Combinations" and
EITF Issue No. 88-16 "Basis in Leveraged Buyout Transactions."

  The allocation of the purchase price was as follows (in thousands):

2. Accounting Policies

 Principles of Consolidation

  The business is conducted through the Company and two wholly owned
subsidiaries of the Company, AGY Yarns Canada and AGY Capital Corp. Significant
intercompany accounts and transactions have been eliminated. As of December 31,
1998, the Company did not have any other subsidiaries.

 Cash and Cash Equivalents

  The Company considers cash on hand, cash deposited in financial institutions
and money market accounts with maturities of less than ninety days at date of
purchase to be cash equivalents. These are stated at cost which approximates
market value.

 Inventories

  Inventories are stated at the lower of cost or market value and include
material, labor and manufacturing overhead. Cost is determined using the first-
in, first-out (FIFO) method.

 Rebuild of Glass Melting Furnaces

  Glass melting furnaces periodically require substantial rebuilding. The time
period between rebuilds varies depending upon the utilization of the furnace.
The Company applies the capital method of accounting for the cost to rebuild
glass melting furnaces. Under this method, costs are capitalized when incurred
and depreciated over the estimated useful lives of the rebuilt furnaces, which
is approximately 14 years.

(2) Accounting Policies--(Continued)


 Property, Plant and Equipment

  Property, plant and equipment are stated at cost, less accumulated
depreciation. Depreciation of property, plant and equipment is calculated
principally on the straight-line method over the estimated useful lives of the
assets. Repairs and maintenance costs are expensed as incurred; major
replacements and improvements are capitalized. When assets are retired or sold,
the cost and related accumulated depreciation are removed from the accounts
with any resulting gain or loss reflected in operations.

  The estimated useful lives of the assets are as follows:

<TABLE>
<S>                                                                  <C>
  Buildings and leasehold improvements.............................. 15-40 Years
  Machinery and equipment...........................................  5-25 Years
</TABLE>

  When events or changes in circumstances indicate that assets may be impaired,
an evaluation is performed comparing the estimated future undiscounted cash
flows associated with the asset to the asset's carrying amount to determine if
a write-down to market value or discounted cash flow is required. Management
does not believe that there are any material impairments at December 31, 1998.

  Alloy metals are an integral part of the Company's installed glass melting
furnaces and therefore are classified as property, plant and equipment in the
accompanying financial statements.

  Alloy metals, consisting of rhodium and platinum, are the primary component
of the heat resistant glass forming bushings in the Company's glass melting
furnaces. Molten glass is passed through the bushings to form glass filaments.
During the manufacturing process, a small portion of the alloy metals is
physically consumed. The portion of the alloy metal physically consumed is
measured at the time a bushing is reconditioned and is charged to income. The
amount of metal loss and the service life of the bushings are dependent upon a
number of factors including the type of furnace and the product being produced.
Based upon historical metal loss, the Company's alloy metals have a useful life
of up to 50 years.

 Revenue Recognition and Concentration of Credit Risk

  Revenues are recognized when title to products passes to the customer. Title
in substantially all cases passes at the point of shipment, but in some
instances does not pass until goods are received by the customer. Two customers
accounted for approximately 36% and 28% of the Company's gross accounts
receivable at December 31, 1998 and 1997, respectively.

  The following table represents a summary of sales to significant customers as
a percentage of the Company's net sales:

 Foreign Currency Translation

  The assets and liabilities of the Company's Canadian operations are
translated from its functional currency to U.S. dollars at the year-end
exchange rates and income and expenses are translated at the average exchange
rates prevailing during the period.

  Prior to the Formation Transactions, the functional currency of Owens
Corning's European operations was the local currency. Accordingly, assets and
liabilities of the European group were translated at the year-end exchange
rates and income and expenses were translated at the average exchange rates
prevailing during the period. Adjustments resulting from the translations were
recorded as a separate component of Net Assets/Members' Interest.

  As of the date of the Formation Transactions, the European operations of AGY
consisted principally of a distributorship. As of the date of the Formation
Transactions, the European operations became a direct and integral component of
the U.S. operations and are not a distinct and separate operation.

 Use of Estimates

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

 Intangible Assets

  Included in intangible assets are goodwill (i.e., excess of acquisition costs
over identifiable assets), patents and trademarks, debt issuance costs and
covenant not to compete. Goodwill represents the excess of cost over the fair
value of tangible and intangible assets acquired. Debt issuance costs are being
amortized over the terms of the respective debt agreements using the interest
method (See Note 5). The Company's policy is to evaluate goodwill and other
intangible assets for possible impairment whenever events or changes in
circumstances indicate that the carrying amount of such assets may not be
recoverable. This evaluation is based on undiscounted operating cashflows that
will result from the use of such assets. When projected future cashflows on an
undiscounted basis are less than the carrying value of the assets, the impaired
assets are written down to net realizable value. The Company believes there is
no impairment at December 31, 1998.

 Other Income

  Other income includes royalty and technical service fees, as well as proceeds
from the sale of scrap material.

 Research and Development

  The Company expenses research and development costs as incurred. These costs
were approximately $225,000 and $500,000 for the periods ended December 31,
1998 and September 30, 1998, respectively.

 Impairment of Long-Lived Assets

  The Company assesses whether its long lived assets are impaired as required
by SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed of," based on an evaluation of undiscounted
projected cash flows through the remaining amortization period. If an
impairment exists, the amount of such impairment is calculated based on the
estimated fair value of the asset. The Company believes there is no impairment
at December 31, 1998.

 Fair Value of Financial Instruments

  The fair value of financial instruments in the accompanying financial
statements approximates the carrying value, unless otherwise disclosed.

 Recently Issued Accounting Standards

  On June 15, 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133"). SFAS 133 is effective for all
fiscal quarters of all fiscal years beginning after June 15, 1999. SFAS 133
requires that all derivative instruments be recorded on the balance sheet at
their fair value. Changes in the fair value of derivatives will be 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. The Company anticipates that, due to its
limited use of derivative instruments, the adoption of SFAS 133 will not have a
significant effect on the Company's results of operations or its financial
position.

 Senior Credit Facility

  In connection with the Formation Transactions, AGY entered into a senior
secured credit agreement, pursuant to which the lenders committed to lend to
AGY up to $315.0 million (the "Senior Credit Facility"), including: (i) a six-
year revolving credit facility in an aggregate principal amount of up to $75.0
million (the "Revolver"); (ii) a six-year term loan in an aggregate principal
amount of $115.0 million ("Term Loan A"); (iii) a seven-year term loan in an
aggregate principal amount of $125.0 million ("Term Loan B" and together with
Term Loan A, the "Term Loans").

  The Senior Credit Facility is collateralized by a first priority lien on
substantially all of the properties and assets of AGY and its respective
domestic subsidiaries, now owned or acquired thereafter, and a pledge of
Porcher Industries' membership interest in AGY. The Senior Credit Facility will
be guaranteed by all of AGY's future domestic subsidiaries.

  At AGY's option, the interest rates per annum applicable to the Revolver and
the Term Loan A is a fluctuating rate of interest measured by reference either
to: (i) LIBOR plus a borrowing margin or (ii) the bank's base rate, which is
the greater of the published prime rate or the overnight federal funds rate
plus 0.5% (the "ABR") plus a borrowing margin. The applicable borrowing margin
for the Revolver and Term Loan A ranges from 1.75% to 3.0% for LIBOR based
borrowings and .5% to 1.75% for ABR based borrowings. The applicable borrowing
margin for the Term Loan B ranges from 3.50% to 3.75% for LIBOR based
borrowings and 2.25% to 2.5% for ABR based borrowings. In October 1998, the
Company entered into interest rate swap agreements which convert the LIBOR
rates of interest on Term Loan A and Term Loan B to 4.92% and 5.04% per annum,
respectively, plus the applicable borrowing margin, in order to limit its
exposure to interest rate fluctuations under the Term Loan portion of the
Senior Credit Facility. These swap agreements remain in effect through the six-
year and seven-year terms of Term Loan A and Term Loan B, respectively. The
notional amount of these swaps was $115,000,000 and $125,000,000 for Term Loan
A and Term Loan B at December 31, 1998, respectively.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

(7) Long-Term Debt--(Continued)

  The interest rate on borrowings outstanding under the Revolver, Term Loan A
and Term Loan B as of December 31, 1998 was 7.79%, 8.38% and 9.13%,
respectively. The fair value of the interest rate swap agreements, representing
the estimated amount that the Company would receive to terminate the swap
agreements, was approximately $1,099,000 and $2,003,000 at December 31, 1998;
however, the Company has no intention of terminating the swap agreements.

  The Senior Credit Facility contains covenants restricting AGY and its
subsidiaries with respect to the incurrence of debt (including guarantees); the
creation of liens; substantially changing the nature of AGY's or its
subsidiaries' businesses; the consummation of certain transactions such as
dispositions of substantial assets, mergers, acquisitions, reorganizations and
recapitalizations; the making of certain investments and loans, non-ordinary
course of business asset sales and capital expenditures; the making of
dividends and other distributions; transactions with affiliates (outside of
trade sales and purchases) and AGY's ability to prepay certain debt. AGY also
is required to comply with certain financial tests and maintain certain
financial ratios. Certain of these financial tests and ratios include: (i)
maintaining a maximum Leverage Ratio; (ii) maintaining a minimum Consolidated
Net Worth (as defined in the Senior Credit Facility); (iii) maintaining a
minimum Interest Coverage Ratio (as defined in the Senior Credit Facility); and
(iv) maintaining a minimum Fixed Charge Coverage Ratio (as defined in the
Senior Credit Facility). At December 31, 1998, the Company was in compliance
with the aforementioned covenants.

  The Senior Credit Facility also contains customary Events of Default. An
Event of Default under the Senior Credit Facility will allow the lenders
thereunder to accelerate or, in certain cases, will automatically cause the
acceleration of, the maturity of the debt under the Senior Credit Facility.
Further, in the event of default, the interest rate would be increased.

 Senior Subordinated Credit Facility

  In connection with the Formation Transactions, AGY entered into the
Subordinated Facility. The Subordinated Facility, which had a maturity of
September 30, 2008, provided for aggregate borrowings in an amount of $150
million and was fully drawn by AGY as of September 30, 1998.

  Amounts outstanding under the Subordinated Facility accrued interest at a
rate equal to the sum (a) of the greater of (i) the three month LIBOR rate or
(ii) a Treasury based rate (based on Treasury securities of the same principal
amount as the Subordinated Facility), plus (b) a margin of 4.25%. The 4.25%
margin increases by .25% per annum at the end of each three-month period during
the term of the Subordinated Facility. The maximum annual rate on the
Subordinated Facility was 18%. The rate of interest on the amounts outstanding
under the Subordinated Facility was 9.51% at December 31, 1998.

  The Company used the net proceeds from the offering of its 9 7/8% Senior
Subordinated Notes due 2009, together with additional borrowings under the
Senior Credit Facility, to repay all amounts outstanding under the Subordinated
Facility (Note 17).

 Other

  The Company has outstanding standby letters of credit at December 31, 1998 of
approximately $512,000 to secure workers compensation obligations. Such letters
of credit expire in October 1999.

 Keepwell Agreement

  In connection with the Formation Transactions, Owens Corning entered into a
Keepwell Agreement to support the liquidity of AGY. In the event that AGY does
not have the liquidity to pay the interest on the Senior Credit Facility or the
9 7/8% Senior Subordinated Notes due 2009 when due, Owens Corning will loan AGY
an amount equal to the aggregate deficiency. Owens Corning's obligations to
make such loans is limited to a maximum aggregate amount of $65 million, and a
maximum annual amount of $20 million. The Owens Corning maximum aggregate
obligation is reduced by $10 million semi-annually beginning in 1999. Any such
loans which are made by Owens Corning will be subordinate to obligations under
the Senior Credit Facility and the Notes. This agreement terminates in January
2002.

 Put Right

  Commencing September 30, 2003, each of the members have the right to sell not
less than all of their ownership interest to AGY (a "Put Right") in the event
certain conditions described below are satisfied. If either of the members
exercises its Put Right, the value of the ownership interest will be determined
by a third party according to the procedures set forth in the operating
agreement. AGY's

(8) Membership Interest/Net Assets and Put Rights--(Continued)

obligation to purchase a member's ownership interest is conditioned upon AGY
financing the purchase with a third party lender while maintaining or obtaining
not less than a B rating on its then outstanding unsecured debt after giving
effect to the purchase. In addition, AGY's ability to fund the Put Right will
be conditioned upon maintaining compliance with the covenants under the Senior
Credit Facility and the Subordinated Credit Facility.

  As of December 31, 1998, AGY could not finance the purchase of all or any
portion of either member's ownership interest and maintain a credit rating of
at least B on its existing unsecured debt. If AGY meets this requirement in the
future, the Company will commence accretion to this estimated redemption value
of each member's ownership interest. Such accreted redemption amount will be
presented outside of the members' interest section of the balance sheet after
total liabilities. Management's estimate of the aggregate value of the members'
ownership interests using the measurement procedures specified in the Operating
Agreement is approximately $250 million.

 Other, net


  Prior to October 1, 1998, the other change in the net assets of the
Predecessor Business reflects the change in the intercompany payable with Owens
Corning related to alloy metals. Alloy metals are owned by Owens Corning's
central alloy operations and were issued to the Predecessor Business as needed
for production. The amount of alloy metals issued to the Predecessor Business
has been included in the opening balance of net assets. When the Predecessor
Business returned alloy metals to the central alloy operations for
reconditioning, the net assets of the Predecessor Business were reduced. When
additional issuances of alloy metals were made to the Predecessor Business, the
net assets of the Predecessor Business were increased.

9. Transactions with Related Parties

  The Company engages in several transactions with related parties. The
following is a description of these transactions.

 Sales

  Porcher Industries and affiliates represented approximately $14,000,000 and
$39,000,000 of AGY's net sales for the periods ended December 31, 1998 and
September 30, 1998, respectively.

 Purchases of Materials

  The Company purchases glass marbles, which are used as an input material in
the production of certain glass yarns, from Owens Corning. Glass marble
purchases were $1,667,000, $2,157,000, $3,047,000 and $2,889,000 for the
periods ended December 31, 1998 and September 30, 1998 and for the years ended
December 31, 1997 and 1996, respectively.

 Glass Forming Bushing Fabrication Services and Alloy Metal Loss


  The glass forming bushings used in the Company's glass melting furnaces
require periodic refurbishing. Refurbishing and fabrication services are
provided to the Company by Owens Corning's central alloy operations. Such
services and alloy metals physically consumed in the manufacturing process are
charged to the Company at actual cost and were $721,000, $2,499,000, $3,200,000
and

10. Employee Benefits

  These disclosures have been restated in accordance with the provisions of
SFAS 132.

 Pension Plan

  Prior to the Majority Purchase, the hourly and salaried employees of the
Predecessor Business participated in Company wide defined benefit plans
maintained by Owens Corning. Under the plans, pension benefits were generally
based on an employee's pay and number of years of service. Contributions to
these pension plans were based on the calculations of independent actuaries
using the projected unit credit method. Plan assets consisted primarily of
equity securities with the balance in fixed income investments. The
unrecognized cost of retroactive amendments and actuarial gains and losses were
amortized over the average future service period of plan participants expected
to receive benefits.

  Pension expense attributed to the Predecessor Business defined benefit
pension plans includes the following (in thousands):

  Under the Majority Purchase, Owens Corning continued to remain responsible
for pension benefits earned through September 30, 1998. However, AGY agreed to
pay for subsidized benefits offered under the plan to participants who retire
before normal retirement age. This subsidized benefit is the result of the plan
paying early retirement benefits which are actuarially larger than benefits
provided at normal retirement age. For those participants under age 55 on
September 30, 1998, the subsidy on the entire retirement benefit (including the
portion of the benefit earned while the

participant was an employee of the Predecessor Business) has been borne by AGY.
This liability of AGY at September 30, 1998 was actuarially calculated to be
$5.1 million. For those employees eligible to retire, AGY is responsible for
only the subsidy on the portion of the benefit earned subsequent to September
30, 1998.

  Additionally, AGY has agreed to be responsible for the service costs under
the plan through December 31, 1999. The amount reimbursable to Owens Corning
attributed to AGY's unfunded contracted responsibility under this agreement
charged to expense for the period October 1, 1998 to December 31, 1998 was
$500,000.

Postretirement

  The employees of the Predecessor Business participated in health care and
life insurance benefit plans for certain retired employees and their
dependents. The heath care plans in the U.S. were unfunded and pay either: 1)
stated percentages of covered medically necessary expenses, after subtracting
payments by Medicare or other providers and after stated deductibles have been
met, or, 2) fixed amounts of medical expense retirement.

  Employees became eligible to participate in the health care plans upon
retirement under the Predecessor Business' pension plans if they had
accumulated 10 years of service after age 45. Some of the plans were
contributory, with some retiree contributions adjusted annually. The
Predecessor Business reserved the right to change or eliminate these benefit
plans subject to the terms of collective bargaining agreements.

  Under the Majority Purchase, AGY assumed the liability for these health care
and life insurance benefits for active employees on September 30, 1998.

  The amount of net postretirement benefits cost attributed to AGY and the
Predecessor Business included the following components (in thousands):

Other Benefit Plan

  Employees of the Predecessor Business also participated in plans that
provided benefits to former or inactive employees after employment but before
retirement under certain conditions. These benefits included, but are not
limited to, salary continuation, supplemental unemployment benefits, severance
benefits, disability related benefits (including workers' compensation), job
training and counseling. The benefits cost liability attributed to the
Predecessor Business at October 31, 1997, as reflected in the statement of net
assets at December 31, 1997 was $6,865,000 including current liabilities of
$850,000. Such plans were not continued as a result of the Majority Purchase.

11. Restructuring and Nonrecurring Costs

  During the first quarter of 1998, the Predecessor Business recorded a $2
million restructuring charge relating to personnel reductions at the Aiken and
Huntingdon plant locations. The charge represents severance costs associated
with the elimination of approximately 100 positions.

  During the period October 1, 1998 to December 31, 1998, the Company incurred
nonrecurring charges of $626,000 related to labor agreement settlements
included in the cost of sales and $268,000 related to relocation costs included
in selling, general and administration expense. An additional $130,000 of costs
associated with software training was incurred and is included in selling,
general and administrative expenses. The operating profit for the period
October 1, 1998 to December 31, 1998 was adversely impacted by $1.3 million
attributable to charges resulting from the purchase accounting adjustment to
reflect the fair value of the inventory as of the date of the Majority
Purchase.

12. Interest Expense

  Interest expense includes the following for the three months ended December
31, 1998 (in thousands):

13. Income Taxes

  The provision for income taxes, income taxes payable and deferred income
taxes included in the accompanying financial statements have been calculated as
if the Predecessor Business, prior to July 1, 1998 operated as a stand alone
entity. Effective July 1, 1998, the Company was established as a limited
liability company, and is not subject to income tax; therefore, the statement
of operations included herein does not reflect income tax expense for any
period subsequent to July 1, 1998. Income tax expense reflected in the
statement of operations for the nine months ended September 30, 1998 represents
the estimated income tax expense attributable to the results of operations of
the Predecessor Business through June 30, 1998. Income tax for the periods
subsequent to the Contributions is the responsibility of the members based on
their respective interest in AGY.

  Deferred income taxes were determined based on the estimated future tax
effects of temporary differences between the financial reporting and tax bases
of assets and liabilities, given the provisions of the enacted tax laws. As a
result of the conversion to a limited liability company, the deferred tax asset
at July 1, 1998 of $10,513 was treated as a deemed distribution and reflected
as a reduction of net assets. Deferred tax consequences of significant
temporary differences existing as of December 31, 1997 are as follows (in

16. Distributions

  Pursuant to the terms of the Operating Agreement, the Company will make an
annual distribution (the "Tax Distribution") from its net cash flows and
permitted borrowings under the Senior Credit Facility to each of Owens Corning
and Porcher Industries in order to fund the taxes payable by each owner on
their proportionate share of the Company's net ordinary income and net capital
gain. In connection with the Majority Purchase, the Company has made a
partnership election to step up the basis of certain of the Company's tangible
and intangible assets. The resulting increase in depreciation and amortization
expense will be allocated wholly to Porcher Industries. As a result, the Tax
Distributions will not be made on a pro rata basis and Porcher Industries will
have an unrecovered distribution amount (the "Deferred Distribution"). The
Deferred Distribution will earn interest at the same rate of interest as the
Senior Credit Facility. Based on the members' estimated taxable income for the
three month period ended December 31, 1998 the Tax Distribution will
approximate $3.1 million of which $1.5 million will be paid in cash to Owens
Corning and $1.6 million will be treated as a Deferred Distribution payable to
Porcher Industries.

17. Subsequent Event

  On January 15, 1999, the Company issued $150 million of 9 7/8% Senior
Subordinated Notes ($147 million net of discount) due 2009. Interest is payable
semiannually beginning in July 1999. Net proceeds of approximately $141.9
million plus additional borrowings under the revolving credit facility were
used to repay outstanding indebtedness of $150 million under the Subordinated
Facility. In addition, debt issuance costs of $3.6 million associated with the
termination of the Subordinated Facility were written off in the first quarter
of 1999.

  The Company's wholly-owned subsidiary, AGY Capital Corp., which was formed
and capitalized on September 24, 1998, is a joint and several obligor of the 9
7/8% Senior Subordinated Notes. AGY Capital Corp. was capitalized with $1,000
of which 1,000 shares of $.01 par value stock were issued. Separate financial
statements or condensed consolidating financial data of AGY Capital Corp. are
not presented because management has determined that they would not be material
to holders of the Company's Senior Subordinated Notes. AGY Capital Corp. has
had no further transactions or activities since the date of formation.

</TABLE>

  During the three months ended March 31, 1999, selling, general and
administrative expenses include approximately $300,000 in nonrecurring
consulting expenses. During this same period, the Company recorded a
distribution to its members as discussed in Note 16. Accordingly, at March 31,
1999, a distribution payable to Owens Corning of $1,548 is included in accrued
liabilities and the balance sheet reflects a deferred distribution of $1,611 to
Porcher Industries.

                PART II. INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

  (a) Advanced Glassfiber Yarns LLC

  Section 18-108 of the Delaware Limited Liability Company Act (the "Act")
empowers a limited liability company to indemnify and hold harmless any member
or manager or other person from and against any and all claims and demands
whatsoever; subject to such standards and restrictions, if any, set forth in
the operating agreement.

  Section 11 of the operating agreement of Advanced Glassfiber Yarns LLC (the
"Company") provides in pertinent part as follows:

    (a) Except as otherwise prohibited by the Act, the Company shall
  indemnify and hold each owner and its affiliates and its officers,
  employees, directors, members, stockholders, managers, agents and
  representatives, and their successors and assigns, and each of the members
  of the Board of Directors and each officer (collectively, the
  "Indemnitees"), harmless from and against any and all losses, claims,
  damages, costs, liabilities and expenses (including without limitation
  costs of investigation and reasonable attorneys' fees) ("Losses") suffered
  or incurred by any and/or all of the Indemnitees (or to which any and/or
  all of the Indemnitees may become subject) arising out of, resulting from,
  based upon or in connection with the management or conduct of the business
  or affairs of the Company or the activities of each such Indemnitee with
  respect thereto, other than those which are the result of willful
  misconduct or gross negligence by such Indemnitee (the "Indemnified
  Damages").

    (b) Any payment by the Company to an Indemnitee hereunder shall be
  increased by an additional amount sufficient to pay all applicable income
  taxes (if any) of any jurisdiction with respect to the total amount
  (including both the initial amount and such additional amount) paid to such
  Indemnitee hereunder.

    (c) To the extent that insurance form third parties has been obtained and
  is available in respect of any Indemnified Damages, the amount of any
  Indemnified Damages shall be reduced by any amount actually recovered by
  the Indemnitee from such third parties (to the extent such reimbursement
  was not taken into account in assessing the amount of Indemnified Damages
  incurred by the Indemnitee) rather than having the Company make any
  payments pursuant to the indemnification obligations contained herein;
  provided that if such proceeds are not readily available, the Board of
  Directors will cause the Company to pay such Indemnified Damages, in which
  event the Company shall be entitled to reimbursement therefor out of the
  proceeds of insurance when and if obtained. The Board of Directors may (but
  shall not be obligated to) obtain, at the expense of the Company, insurance
  against any Indemnified Damages whether or not the Company would, pursuant
  to this Section 11.1, be required to indemnify any Indemnitee in respect
  thereof.

    (d) The Company shall, at its sole cost and expense, (i) maintain, with
  insurers or underwriters of national standing, in the name of the Company,
  (x) liability insurance to protect members of the Board of Directors and
  the officers, and (y) employee fidelity and other insurance consistent with
  industry practice, in the case of (x) and (y), in at least such amounts as
  are sufficient to cover reasonable risks of loss and are consistent with
  industry practice, and (ii) pay all premiums and other sums payable in
  respect of maintaining such insurance.

  (b) AGY Capital Corp.

  Under Section 145 of the General Corporation Law of the State of Delaware, a
corporation may indemnify its directors, officers, employees and agents and
its former directors, officers, employees and agents and those who serve, at
the corporation's request in such capacities with another enterprise,

                                     II-1
<PAGE>

against expenses (including attorney's fees), as well as judgments, fines and
settlements in nonderivative lawsuits, actually and reasonably incurred in
connection with the defense of any action, suit or proceeding in which they or
any of them were or are made parties or are threatened to be made parties by
reason of their serving or having served in such capacity. Delaware law
provides, however, that such person must have acted in good faith and in a
manner he or she reasonably believed to be in (or not opposed to) the best
interests of the corporation and, in the case of a criminal action, such person
must have had no reasonable cause to believe his or her conduct was unlawful.
In addition, Delaware law does not permit indemnification of any action or suit
by or in the right of the corporation, where such person has been adjudged
liable to the corporation, unless, and only to the extent that, a court
determines that such person fairly and reasonably is entitled to indemnity for
costs the court deems proper in light of liability adjudication. Indemnity is
mandatory to the extent a claim, issue or matter involving a present or former
director or officer has been successfully defended.

  AGY Capital Corp.'s certificate of incorporation and bylaws provide, under
certain circumstances, for the indemnification of AGY Capital Corp.'s present
or former directors, officers, employees, agents and persons who, at the
request of AGY Capital Corp., are or were serving in a similar capacity for
another corporation or entity. These provisions also allow the Board of
Directors to purchase and maintain insurance on behalf of AGY Capital Corp.'s
present or former directors, officers or persons who are or were serving at the
request of AGY Capital Corp. as a director or officer of another corporation or
entity.

Item 22. Undertakings

  (a) Each of the undersigned Registrants hereby undertakes:

    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this Registration Statement:

      (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933 (the "Securities Act");

      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which,

                                     II-3
<PAGE>

    individually or in the aggregate, represent a fundamental change in the
    information set forth in the Registration Statement. Notwithstanding
    the foregoing, any increase or decrease in volume of securities offered
    (if the total dollar value of securities offered would not exceed that
    which was registered) and any deviation from the low or high end of the
    estimated maximum offering range may be reflected in the form of
    prospectus filed with the Commission pursuant to Rule 424(b) if, in the
    aggregate, the changes in volume and price represent no more than a 20
    percent change in the maximum aggregate offering price set forth in the
    "Calculation of Registration Fee" table in the effective Registration
    Statement; and

      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or
    any material change to such information in the Registration Statement;

    (2) That, for the purpose of determining any liability under the
  Securities Act, each such post-effective amendment shall be deemed to be a
  new registration statement relating to the securities offered therein, and
  the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof.

    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.

  (b) Insofar as indemnification for liability arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, each of the
Registrants has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
a Registrant of expenses incurred or paid by a director, officer or
controlling person of such Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrants
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

  (c) Each of the undersigned Registrants hereby undertakes to respond to
requests for information that is incorporated by reference into the prospectus
pursuant to Items 4, 10(b), 11, or 13 of Form S-4, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request.

  (d) Each of the undersigned Registrants hereby undertakes to supply by means
of a post-effective amendment all information concerning a transaction, and
the company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

     Re:  Registration Statement on Form S-4 (No. 333-72305)



Ladies and Gentlemen:

     We have acted as legal counsel to Advanced Glassfiber Yarns LLC and AGY
Capital Corp., a Delaware limited liability operating company and a Delaware
corporation respectively (collectively, the "Companies"), in connection with the
filing of the above-referenced Registration Statement (the "Registration
Statement") with the Securities and Exchange Commission (the "Commission") to
register under the Securities Act of 1933, as amended (the "Act"), $150,000,000
principal amount of the Companies' 9 7/8% Senior Subordinated Notes due 2009
(the "Exchange Notes") to be issued under that certain Indenture dated as of
January 21, 1999 (the "Indenture") between the Companies and the Bank of New
York, as Trustee (the "Trustee"), in exchange for the identical principal amount
of any and all of the Companies' outstanding 9 7/8% Senior Subordinated Notes
due 2009 (the "Old Notes"). This opinion letter is rendered pursuant to Item 21
of Form S-4 and Item 601(b)(5) of Regulation S-K.

     We have examined the Certificate of Formation and the Amended and Restated
Limited Liability Company Operating Agreement of Advanced Glassfiber Yarns LLC
and the Certificate of Incorporation and Bylaws of AGY Capital Corp.; records of
proceedings of the Board of Directors, or committees thereof, the members of
Advanced Glassfiber

Yarns LLC and the shareholders of AGY Capital Corp. deemed by us to be relevant
to this opinion letter; the proposed form of Exchange Note; the Indenture, and
the Registration Statement. We also have examined originals or copies, certified
or otherwise identified to our satisfaction, of such other corporate records and
documents of the Companies, such certificates of officers of the Companies and
public officials, and such other records and documents as we have deemed
necessary or appropriate as a basis for the opinions hereinafter expressed. In
such examination, we have assumed the genuineness of all signatures, the legal
capacity of all natural persons, the authenticity and completeness of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified, conformed, photostatic or facsimile
copies, and the authenticity of the originals of such copies, and we have
assumed all certificates of public officials to have been properly given and to
be accurate.

     As to certain factual matters relevant to this opinion letter, we have
relied upon the representations and warranties contained in the above-referenced
certificates of officers of the Companies and public officials. Except to the
extent expressly set forth herein, we have made no independent investigations
with regard thereto, and, accordingly, we do not express any opinion as to
matters that might have been disclosed by independent verification.

     Our opinion set forth below is limited to the laws of the State of Georgia,
the laws of the State of New York, the Delaware General Corporation Law and the
federal securities laws, and we do not express any opinion herein concerning
any other laws.

     On the basis of the foregoing, and subject to the limitations set forth
herein, we are of the opinion that, upon due execution of the Exchange Notes by
the Companies, due authentication thereof by the Trustee in accordance with the
Indenture and issuance and delivery thereof against exchange of the Old Notes as
provided by the Prospectus included in the Registration Statement, the Exchange
Notes will be validly issued and will constitute legally binding obligations of
the Companies entitled to the benefits of the Indenture and enforceable against
the Companies in accordance with their terms except to the extent that (a)
enforceability may be limited by applicable bankruptcy, insolvency, liquidation,
reorganization, moratorium and other laws relating to or affecting the rights
and remedies of creditors generally, and (b) the remedy of specific performance
and other forms of equitable relief may be subject to certain defenses and to
the discretion of the court before which proceedings may be brought (regardless
of whether enforceability is considered in a proceeding in equity or at law).

     We consent to the filing of this opinion letter as an exhibit to the
Registration Statement and to the use of our name under the heading "Legal
Matters" in the Prospectus constituting a part thereof. In giving such consent,
we do not thereby admit that we are

within the category of persons whose consent is required under Section 7 of the
Act or the rules and regulations of the Commission thereunder.

     This opinion letter is being furnished by us to the Companies and the
Commission solely for the benefit of the Companies and the Commission in
connection with the Registration Statement and is not to be used, circulated,
quoted or otherwise relied upon by any other person, or by the Companies or the
Commission for any other purpose, without our express written consent. The only
opinion rendered by us consists of those matters set forth in the fifth
paragraph hereof, and no opinion may be implied or inferred beyond those
expressly stated. This opinion letter is rendered as of the date hereof, and we
have no obligation to update this opinion letter.

                           BORATES SUPPLY AGREEMENT

                                    BETWEEN

                                 OWENS CORNING

                                      AND

                         ADVANCED GLASSFIBER YARNS LLC



                        DATED AS OF SEPTEMBER 30, 1998
<PAGE>

                           BORATES SUPPLY AGREEMENT


This Borates Supply Agreement (the "Agreement") is executed on this 30th day of
                                    ---------
September, 1998, by and between OWENS CORNING, a Delaware corporation
("Seller"), and ADVANCED GLASSFIBER YARNS LLC, a Delaware limited liability
  ------
company ("Buyer"), and shall be governed by the following clauses.
          -----

     WHEREAS, Seller has entered into an Agreement (the "Etibank Agreement")
dated January 1, 1998, by and between Etibank and Seller under which Etibank has
agreed to mine, process, sell and deliver     *     and     *     (collectively,
"Products") to Seller; and

     WHEREAS, Buyer requires certain Borate Products for use in its own
production facilities.

     NOW, THEREFORE, Seller and Buyer agree as follows:

1.    SALE AND PURCHASE OF PRODUCTS.
      -----------------------------

     1.1. THE PRODUCTS.  Subject to the terms and conditions herein set forth,
          ------------
          Seller agrees to sell, and Buyer agrees to purchase and accept its
          requirements for the Products.  The Products and the specifications
          for the Products (the "Product Specifications") are more fully
                                 ----------------------
          described in Exhibit A attached hereto and made a part hereof.  Buyer
          agrees that it is purchasing the Products solely for its own use in
          its own facilities and that it will not resell the Products to any
          third party.

     1.2. NATURE OF OBLIGATION.  In the event that Seller is unable purchase or
          --------------------
          obtain sufficient quantities of one or more Products for Owens Corning
          and Buyer for any reason including but not limited to a Force Majeure
          Event (as defined in paragraph 11 of this Agreement), the
          unavailability or insufficient availability of one or more Products,
          termination of the Etibank Agreement (by either party thereto, with or
          without cause), unsatisfactory quality of one or more Products,
          failure to perform by any person or party other than Seller with
          respect to the sale, delivery, shipping or storage of one or more
          Products, then, subject to the next succeeding sentence, Seller shall
          have no obligation under this Agreement. Notwithstanding the
          foregoing, should Seller decide to sever its supply arrangement with
          Etibank for any reason, Seller can terminate this Agreement at any
          time, provided that it has given Buyer 180 days' written notice prior
          to the termination of the arrangement with Etibank. In the event that
          Etibank will not allow Seller to resell the Products to Buyer or if
          Etibank establishes a marketing arrangement in North America
          prohibiting Seller to resell the Products to Buyer,

- -----------

* Omitted pursuant to a request for confidential treatment. The omitted portions
  have been separately filed with the Securities and Exchange Commission.

<PAGE>

          then Seller can terminate this Agreement. If Seller continues to
          purchase the Products from any other supplier or Etibank, Seller
          agrees to continue to supply the Products to Buyer under this
          Agreement.

     1.3. Buyer agrees that Buyer will not, except in case Seller cannot provide
          sufficient amount of the Products exceeding the Maximum Volume and
          with the express written consent of Seller, purchase or accept the
          Products from or approach any third party or Etibank.

     1.4. Buyer acknowledges and agrees that Seller, at its sole discretion, may
          request Buyer to purchase the Products from ABC, Inc. ("ABC"),
          Seller's sole distributor for the Products, provided ABC accepts the
          pricing for the Products as provided in Section 4.


2.   TERM; CONTRACT YEAR.
     -------------------

     2.1. TERM.  This Agreement shall be effective as of the date of execution
          ----
          and, unless earlier terminated as provided herein, shall continue in
          full force and effect for the period of seven years and three months
          through and including December 31, 2005.  This Agreement shall be
          automatically renewed for a period equal to any renewal or extension
          of the term of the Etibank Agreement unless terminated by either party
          upon 90 days' prior written notice.  The initial term, together with
          all renewal periods thereof, is referred to hereinafter as the "Term".
                                                                          ----

     2.2. CONTRACT YEAR.  For purposes of this Agreement, each of the following
          -------------
          periods is a "Contract Year".
                        -------------

          2.2.1  FIRST CONTRACT YEAR.  The first Contract Year shall be the
                 -------------------
                 period from the date hereof until December 31, 1998; and

          2.2.2  SUBSEQUENT CONTRACT YEARS.  Subsequent Contract Years shall be
                 -------------------------
                 each successive twelve month period beginning January 1 and
                 ending December 31 during the Term of the Agreement.


3.   ESTIMATES; RELEASES; DELIVERY.
     -----------------------------

     3.1. BUYER'S CONTRACT YEAR ESTIMATES.  Within 30 days of the execution of
          -------------------------------
          this Agreement and, on or before September 30 of each Contract Year
          thereafter during the Term of this Agreement, Buyer shall provide
          Seller with Buyer's good-faith estimates of Buyer's requirements for
          the Products, by type, and by calendar quarter, for the next
          succeeding Contract Year (the "Contract Year Estimates").  Such
                                         -----------------------
          Contract Year Estimates shall be subject to the conditions set forth
          in

                                       2
<PAGE>

          paragraph 1.2 of this Agreement. The aggregate quantity of the
          Products set forth in the Contract Year Estimates shall be the maximum
          quantities of the Products that Seller is obligated to sell and
          deliver to Buyer during the relevant Contract Year and shall be the
          minimum quantities of Products that Buyer is obligated to purchase
          during the relevant Contract Year. In addition, Seller is not required
          to sell and deliver to Buyer more than ten percent (10%) of the
          Contract Year Estimates in any given month.

     3.2. MAXIMUM VOLUME.  Buyer agrees to purchase and Seller agrees to sell a
          --------------
          maximum quantity of 9,289 tons of     *    and 7,253 tons of    *
          ("Maximum Volume").  This maximum volume represents the average usage
          by Seller of     *     for the past three years. Buyer can elect to
          increase quantities of     *     and reduce equal quantities of
              *    subject to availability.  Seller agrees to supply Buyer on a
          basis of first available quantity.  For any quantity exceeding Maximum
          Volume, Seller will supply Buyer only after Seller's own needs are
          satisfied.

     3.3. SELLER'S ASSURANCES.  If for any reason Seller believes it will be
          -------------------
          unable to deliver all or any portion of Buyer's Contract Year
          Estimates or Refined Estimates, Seller shall immediately notify Buyer
          within ten (10) days of the date of receipt of Buyer's respective
          estimates. Such notification shall not relieve Seller of any of its
          obligations under this Agreement.

     3.4. ORDERS FOR THE PRODUCTS/SHIPMENT.  Orders for the Products shall be
          --------------------------------
          made, at Buyer's discretion, by Buyer issuing signed purchase orders
          to Seller. The orders shall be submitted by authorized personnel of
          Buyer no later than 30 days' prior to the desired date of delivery and
          shall set forth the following: a statement identifying the order with
          this Agreement; the number by which the order shall be identified; the
          quantity of the Products to be delivered; the date of delivery; and
          invoicing instructions. Subject to the volume limitations set forth in
          paragraphs 3.1, 3.2 and 3.3 there shall be no limitation on the number
          of orders issued hereunder. In the event Buyer places an order which
          would exceed its Contract Year Estimate or if Buyer requires a change
          in the quantity of more than 10%, type or delivery date of Products to
          meet customer requirements, Seller may, but is not obligated to, fill
          such order or make such changes. For these purposes, Seller shall
          notify Buyer in writing whether it will be able to fill any order
          which exceeds Buyer's Contract Year Estimate or which requires a
          change in the quantity, type or delivery date of Products within the
          10 days following its receipt of such an order.

     3.5. DELIVERY. All Products will be sold to Buyer FOB Kings Creek, South

4.   PRICE FOR THE PRODUCTS.
     ----------------------

     4.1. The price for the Products sold will equal Seller's cost to purchase,
          transport, process and terminal the sold Products (the "Cost")
          including a fixed administrative charge of $150,000 to be paid pro-
          rata with Product deliveries. If Buyer purchases less than 50% of the
          Maximum Volume, the administrative charge will be reduced by 50%.
          Prices shall be in United States Dollars. Exhibit B provides a list of
          the typical cost items covered under the Cost

     4.2. Buyer acknowledges and agrees that Seller will not provide Buyer a
          copy of the Etibank Agreement. Seller hereby agrees to provide Buyer
          with sufficient proof of the Cost and purchased quantity of the
          Products.

5.   TITLE AND RISK OF LOSS.
     ----------------------

The Products sold pursuant to this Agreement shall be delivered to Buyer as
provided in paragraph 4, and title and risk of loss shall pass to Buyer at the
time the Products leave Seller's processor's facility in Kings Creek, South
Carolina.

6.   TERMS OF PAYMENT.
     ----------------

Seller shall invoice Buyer with each delivery of the Products hereunder. Payment
of each invoice shall be made by Buyer within 15 days from the date of Seller's
invoice. Seller shall charge interest equal to the "base rate" of Citibank N.A.
as announced from time to time plus 2.0% per annum beginning on the 16th day
after the invoice date if not then paid in full. Remittance of interest under
this section shall be made in full without any reduction for any withholding or
other taxes. If withholding taxes or other taxes are applicable as prescribed
under laws of the payor country, Buyer shall remit the withholding taxes or
other taxes to the proper governmental agencies in such country on a timely
basis and supply Seller with a withholding tax receipt or other evidence of
payment as soon as legally possible.


7.   TAXES, EXCISES AND OTHER CHARGES.
     --------------------------------

Except for such taxes which Seller is required by law to collect from Buyer,
each party shall be responsible for payment of such taxes as such party is
required to pay under applicable law, including local, state, federal or foreign
law, and which are based upon or measured by the production, sale,
profitability, transportation, delivery or use of the Products sold and
delivered hereunder. Seller shall show VAT taxes, if applicable, separately on
its invoice.

8.   CHANGES, MODIFICATIONS OR SUBSTITUTIONS.
     ---------------------------------------

Buyer understands and acknowledges that, although there is no obligation to do
so, Etibank, from time to time, to improve the efficiency in the manufacture or
use of the Products, may make changes to, modify or make improvements to the
Products, or substitute newly designed products for the Products. If during the
Term of this Agreement Seller shall propose to make changes, modifications or
improvements to the Products or shall substitute newly designed products for any
of the Products, Seller shall advise Buyer that the change, improvement,
modification or substitution is contemplated. As soon as practicable thereafter,
Seller shall provide Buyer samples of the proposed changed, modified, improved
or substitute product in sufficient laboratory test quantity to enable Buyer to
test and qualify such product in Buyer's manufacturing process. If Etibank
commences commercial manufacture of the changed, modified, improved or
substitute product and the product is qualified by Buyer, the product shall
become a Product and the specifications shall become Product Specifications
hereunder.

9.   SELLER'S DISCLAIMER OF WARRANTY.
     -------------------------------

          BUYER ACKNOWLEDGES THAT ANY SALES MADE TO BUYER HEREUNDER ARE ON AN
          ACCOMMODATION BASIS AND SELLER MAKES NO OTHER REPRESENTATION OR
          WARRANTY OF ANY KIND WITH RESPECT TO THE PRODUCTS DELIVERED HEREUNDER,
          WHETHER EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF
          MERCHANTABILITY, FITNESS FOR A PARTICULAR USE OR PURPOSE, EVEN IF
          DISCLOSED TO SELLER, AND SELLER HEREBY DISCLAIMS ANY SUCH OTHER
          REPRESENTATION OR WARRANTY.


10.  LIMITED WARRANTY.
     ----------------

Seller warrants that the Products sold to Buyer shall be owned by Seller and
shall be free and clear of all liens and encumbrances, and that Seller shall
have complied with all applicable laws, regulations, ordinances and codes
concerning the Products. However, Seller does not warrant that the Products, in
fact, are of a type and quality desired or requested by Buyer, and Buyer's sole
and exclusive remedy for defects in the Products shall be to request that Seller
pursue a claim against Etibank or such other source, shipper or handler of the
Products as may have caused any such defects, at Buyer's own expense.

11.  FORCE MAJEURE.
     -------------

Neither party shall be liable to the other for delay or failure to perform in
whole or in part, by reason of contingencies or events which: (i) are beyond the
reasonable control of the party whose performance is affected, (ii) are
unforeseeable, and (iii) could not have been reasonably prevented, whether
herein specifically enumerated or not (a "Force Majeure Event"). These
contingencies include, among others, act of God, act of war, revolution, riot,
acts of public enemies, fire, explosion, breakdown of plant, strike, lockout,
labor dispute, casualty or accident, earthquake, flood, cyclone, tornado,
hurricane or other windstorm, or by reason of any law, order, proclamation,
regulation, ordinance, demand, requisition or requirement or any other act of
any governmental authority, foreign or domestic, local, state or federal
(provided that the Force Majeure Event does not arise due to or is connected in
any way with a violation by party hereto of any law, order, proclamation,
regulation, ordinance, demand, requisition or requirement of any governmental
authority) except that contingencies shall not include a downturn in Buyer's
business or general economic downturn. A party so affected by a Force Majeure
Event shall: (i) promptly give written notice to the other party whenever such
contingency or other act becomes reasonably foreseeable (including an estimate
of the expected duration of the Force Majeure Event and its probable impact on
the performance of such party's obligations hereunder); (ii) exercise all
reasonable efforts to continue to perform its obligations hereunder; (iii) use
its commercially reasonable best efforts to overcome or mitigate the effects of
the contingency as promptly as possible and (iv) promptly give written notice to
the other party of the cessation of such contingency. Neither party, however,
shall be required to resolve a strike, lockout or other labor problem in a
manner which it alone does not deem proper and advisable. In no event shall any
Force Majeure Event excuse party's failure to pay when due any monetary
obligation hereunder. In the case of any Force Majeure Event relied on by
Seller, Seller agrees that it shall treat Buyer no less favorably than the most
favorably treated Affiliate or customer of Seller in dealing with or adjusting
to the consequences of such Force Majeure Event and in relation to the
allocation of any Products, the production or availability of which may have
been interrupted or diminished.

Deliveries of the Product omitted due to any Force Majeure Event affecting
Seller or Buyer shall, without liability, reduce by an equivalent quantity the
quantity of Products to be sold and delivered during the period in which the
Force Majeure Event occurred.  To determine the quantity of Products that would
have been sold, the parties shall assume that Buyer's most recent Refined
Estimates would have been purchased on a ratable basis.

12.  DEFAULT.
     -------

Except as otherwise specifically provided in this Agreement, if either party
fails to perform any of the terms of this Agreement, (a) the other party may
defer its performance under this Agreement until the default is cured by the
defaulting party, or (b) at its option, the party may treat such default as a
breach of the entire Agreement and, if such default is not cured within 30 days
after the giving of notice thereof to the defaulting party (or, in the case of
default in payment of monies, within 10 business days), may immediately
terminate this Agreement upon

                                       6
<PAGE>

notice to the defaulting party. This Agreement shall terminate automatically,
without necessity of notice, in the event Buyer or Seller makes an assignment
for the benefit of creditors generally, is adjudicated bankrupt or in the event
of the filing of any voluntary or involuntary petition in bankruptcy against
Buyer or Seller or the appointment of a receiver for Buyer or Seller or any
substantial part of their respective properties.


13.  APPLICABLE LAW.
     --------------

This Agreement shall be governed by, and construed in accordance with, the laws
of the State of New York applicable to a contract executed and performed in such
State without giving effect to the conflicts of law principles thereof.


14.  ENTIRE AGREEMENT.
     ----------------

This Agreement sets forth the entire agreement and understanding of the parties
with respect to the subject matter hereof and supersedes all prior
understandings, negotiations, and dealings between the parties hereto with
respect to this subject matter. No agreement or understanding, oral or written,
in any way purporting to modify the terms hereof shall be binding on either
party hereto unless contained in a written document expressly referring to this
Agreement and duly executed by both parties. There are no representations or
warranties made by one party to the other except as expressly set forth in this
Agreement. In case of a conflict between any of the terms of any purchase order
of Buyer or any acknowledgment by Seller of the purchase order and any of the
terms set forth in this Agreement, the terms of this Agreement shall control. No
additional terms or conditions of sale other than those contained in this
Agreement shall be effective unless approved in writing by an authorized
representative of Seller and Buyer.


15.  SUCCESSORS AND ASSIGNS.
     ----------------------

This Agreement shall be binding upon and shall inure to the benefit of both
parties and their respective successors and assigns. Except as otherwise
expressly provided herein, this Agreement shall not be assigned by either party
hereto without the express prior written consent of the other party, and any
attempted assignment, without such consents, shall be null and void.
Notwithstanding any nonassignment provisions contained in this Section 15,
Buyer, or any permitted assignee or transferee of Buyer, may assign or otherwise
transfer some or all of its rights and/or obligations hereunder (i) to any
entity or entities, or any assignee of such entity or entities, providing

or entities providing to Buyer, Buyer's Affiliates, or to any such permitted

<PAGE>

Buyer, provided that (x) such Affiliate shall agree with Seller and its
permitted assignees or transferees, if any, in writing to assume the Buyer's
obligations hereunder and (y) any such assignment to an Affiliate of the Buyer
shall not relieve the Buyer from its obligations hereunder or (iii) to any
entity to which Buyer, or any assignee or transferee of Buyer, assigns, sells,
transfers or otherwise conveys (A) all or substantially all of the assets
constituting the Business (a "Complete Assignment") or (B) all or substantially
all of the assets constituting either the Aiken Facility, the Huntingdon
Facility or the South Hill Facility (a "Partial Assignment"), provided that such
acquiring entity agrees with and acknowledges in writing to Seller and its
permitted assignees or transferees, if any, that this Agreement shall be binding
upon and enforceable against such entity as though such acquiring entity were
Buyer and that such entity shall perform all of Buyer's obligations hereunder.
Notwithstanding any nonassignment provisions contained in this Section 15,
Seller, or any permitted assignee or transferee of Seller, may assign or
otherwise transfer some or all of its rights and/or obligations hereunder (i) to
any Affiliate of Seller, provided that (x) such Affiliate shall agree with Buyer
and its permitted assignees or transferees, if any, in writing to assume the
Seller's obligations hereunder and (y) any such assignment to an Affiliate of
the Seller shall not relieve the Seller from its obligations hereunder or (ii)
to any entity to which Seller, or any assignee or transferee of Buyer, assigns,
sells, transfers or otherwise conveys any portion of its business which owns,
licenses, or uses Business Patents or Business Know How (as each is defined in
the Patent and Know How License Agreement), provided that such acquiring entity
agrees with and acknowledges in writing to Buyer and its permitted assignees or
transferees, if any, that this Agreement shall be binding upon and enforceable
against such entity as though such acquiring entity were Seller and that such
entity shall perform all of Seller's obligations hereunder. To the extent that
assignment and/or transfer of any of the rights, privileges, and/or obligations
is permitted, this Agreement shall be binding on, and except as otherwise
expressly provided, shall inure to the benefit of, the legal successors,
assigns, or representatives of the parties.

     material suppliers.  The relationship is a special long-term commitment
     between  Composites and its suppliers that will accomplish the following:

     (1)  Provide a product and/or service which meets our fitness-for-use
          criteria.

     Owens Corning and our suppliers are committed to sharing information that
     will aid in achieving continual improvements in the products and services
     supplied and in the Owens Corning processes in which they are used.  This
     should result in lower manufacturing costs, less variable products and
     enhanced Owens Corning customer satisfaction through manufacturing
     stability.

B.   FITNESS-FOR-USE CRITERIA
     ------------------------

     This document specified the fitness-for-use criteria the material must
     meet.  Any shipment that does not conform to all these criteria shall not
     be shipped to an Owens Corning user-plant.

C.   PRODUCT CHARACTERISTICS
     -----------------------

     There are six sections of product characteristics, C1-C6.  Each section has
     a specific fitness-for-use criteria.  Sections C.2-C.6 are self-
     explanatory.  However, Section C.1, the Chemical Composition section, is
     rather complex, so the following clarifications have been added:

          The oxide/elements are divided into one of two categories, either * or
          *.  * are those which are known to require some particular attention
          on the part of the supplier to insure the specification is met.  The
          attention may be tight control of mining or blending of mine ores or
          extra attention to some process variable.  * are those which are known
          to generally stay within the specification and exhibit acceptable
          consistency due to the nature of the deposit and/or the process.  They
          only require monitoring to show evidence that their conformance to the
          specification continues.  The difference between * and * is the amount
          of attention paid by the supplier and the frequency of the testing
          required by

          Owens Corning. However, Owens Corning reserves the right to reject
          material based on * or *.

          Based on the supplier's production planning, the material has
          calculable average values for all oxides/elements.  The specification
          is based on the supplier continuing to operate his process such that
          these average values, or "Target Nominals" are maintained.  For
          selected key oxides/elements (those listed in Section C 6.1), the
          upper and lower specification limits are defined by adding and
          subtracting * the maximum acceptable variation from the "Target
          Nominal" value.  The other oxides/elements have a lower or upper
          specification limit based on Owens Corning's fitness-for-use criteria.

          This specification does NOT require that a moving average of
          individual shipment values equal the "Target Nominal".  It is required
          that every shipment be within the specification limits.  It is a goal
          that the variation of critical oxides/elements be reduced and that the
          shipment values approach random variation around the "Target Nominal".

          Additional explanations and requirements for the Chemical Composition
          are contained in Section C.6, "TECHNICAL NOTES".

C.3  CONTAMINATION
     -------------

     The finished product may not contain any contaminants that are deleterious
     to the Owens Corning processes.  Contamination, both organic and inorganic,
     including but not limited to * shall be avoided throughout the storage,
     processing, and rail or truck loading of the shipment.

     The ore deposit may contain trace amounts of * . As part of the
     qualification procedure. Owens Corning has measured the level of these
     contaminants * and determined it to be acceptable. Hereafter, the supplier
     is responsible for measuring the level of * contamination as new ore
     deposits are opened to insure the level has not changed.


C.4  LABORATORY CERTIFICATION
     ------------------------

     The chemical laboratory must be certified by Owens Corning per procedure *.
     Any change in analytical procedure requires re-certification.  If the
     supplier does not employ a certified chemical laboratory, then he must
     submit a schedule by which his chemical laboratory will achieve
     certification.  This schedule must be mutually agreed upon by the supplier
     and Owens Corning.


C.5  SUPPLY OF TEST DATA
     -------------------

     The supplier shall provide the following data to the Owens Corning user-
     plant on the per shipment basis.  *, percent retained on the * and *
     sieves, and percent through the * sieve.  Oxides and elements designated as
     "*" shall also be provided at the intervals listed in Section C.1.  Data
     describing the Chemical and Physical Composition.  Section C.1 and C.2

     respectively, shall be transmitted to the Owens Corning user-plant and
     received prior to unloading.

     In addition, complete chemistry of * and *, as described in Section C.1,
     will be provided to Batch & Melting COE, Granville, Ohio, for the last five
     (5) railcars of each lot and the first five (5) railcars of each lot.

     The "*" are to be obtained from the pre-shipment sample as defined in
     Section E (below) with the exception of *, and *, which will be supplied by
     the Analytical Services Laboratory of Owens Corning, based upon the loading
     composite for each shipment lot.  The chemical analyses shall be generated
     by a laboratory that is certified by the Analytical Services Laboratory of
     Owens Corning as described in Section C.4.

     Control charts for * , as described in Section C.6.2, will be provided to
     Batch & Melting COE on a monthly basis.

C.6  TECHNICAL NOTES
     ---------------

     1.   Should long-term production planning indicate a need to shift a target
          nominal, for instance, to optimize reserves or borate lot shipment
          changes, the supplier may propose a change in the specification limits
          for *.  The supplier must then  propose a target nominal value for the
          oxide(s), and any proposed change must meet the boundary limits beyond
          which no product is acceptable.  The change must also meet the limit
          on allowed variation.  Those limits are:

                         Boundary Limit    Maximum Range
                         --------------    -------------

          *                     *                *

          The upper specification for the oxide shall be set as the new target
          nominal plus * of the maximum range.  The lower specification limit
          shall be set as the target nominal minus * of the maximum range.  If
          the proposed specification results in a violation of the boundary
          limit listed above, the Batch & Melting COE Laboratory in Granville,
          Ohio, must be informed immediately.

          The Batch & Melting COE must be consulted on any proposed change to
          the "Target Nominals" for * before the upper/lower specification
          limits are set.  The new specification will take effect on a date
          mutually acceptable to the supplier and to Batch & Melting COE.

     2.   * is a critical process variable with respect to our manufacturing
          process and our finished glass product.  The process capability for *
          must be established and control charts maintained.

                     CONFIDENTIAL TREATMENT REQUESTED [*]
<PAGE>

          Any assignable causes which result in out-of-control incidents should
          be investigated and appropriate action taken.

     3.   Significant shifts in organic carbon of the finished product will
          impact the manufacturing process at the Owens Corning user-plant.  The
          supplier must inform the Owens Corning user-plant when there is a
          change in fuel source within the supplier's manufacturing process.


D.   TEST METHODS
     ------------

     The Supplier may use test methods at his discretion provided that they
     yield results which conform to *.  Owens Corning test methods are
     documented in the "Manual of Procedures for Glass Control".

E.   PRESHIPMENT SAMPLING
     --------------------

     For each shipment, the supplier shall obtain a representative sample of the
     material directly loaded for shipment or stored in the bin from which the
     shipment was loaded.  A sample library must be maintained for a minimum
     period of 10 weeks.  A representative sample is one which conforms to the
     principles of probability sampling and sample size selection as defined in
     ASTM Methods * and *.  An example of such sampling can be found in ASTM
     Methods *.  At requested frequency, a * gram minimum split of the
     representative sample shall be sent to the Owens Corning user-plant as soon
     as possible after loading.  If a representative sample is currently
     unobtainable, the supplier shall investigate alternate methods of sampling.

F.   REJECTIONS
     ----------

     Owens Corning reserves the right to reject upon receipt, and hold for
     vendor's disposal, any portion or all of the material furnished under this
     specification which does not conform to all of the requirements set forth
     herein.  Rejection of out-of-specification material will be based solely on
     Owens Corning chemical and physical evaluation.

     Rejection of material based on non-compliance with Section C.1 (CHEMICAL
     COMPOSITION) or Section C.2 (PHYSICAL COMPOSITION) can only be based on
     testing of a representative sample (see Section E above for the definition
     of a representative sample).  If a representative sample is not available
     or cannot be obtained, or if the original representative sample has been
     compromised (i.e. contaminated, lost, etc.), the sample to be used for
     deciding compliance to this specification shall be determined by the Batch
     & Melting COE Laboratory of Owens Corning.

A.   GUIDING PHILOSOPHY FOR MATERIAL PURCHASES
     -----------------------------------------

     Owens Corning will enter into quality partnerships with key production
     material suppliers.  The relationship is a special long-term commitment
     between Composites and its suppliers that will accomplish the following:

(1)  Provide a product and/or service which meets our fitness-for-use criteria.

(2)  Provide continuing increased value to Owens Corning.

(3)  Commit Owens Corning suppliers to use statistical process control
     principles in their manufacturing processes.

     Owens Corning and our suppliers are committed to sharing information that
     will aid in achieving continual improvements in the products and services
     supplied and in the Owens Corning processes in which they are used.  This
     should result in lower manufacturing costs, less variable products and
     enhanced Owens Corning customer satisfaction through manufacturing
     stability.

B.   FITNESS-FOR-USE CRITERIA
     ------------------------

     This document specified the fitness-for-use criteria the material must
     meet.  Any shipment that does not conform to all these criteria shall not
     be shipped to an Owens Corning user-plant.

</TABLE>

NOTE:  Physical analysis must be performed according to * procedures using *
sieves.

C.3    CONTAMINATION
       -------------

       The finished product may not contain any containments that are
       deleterious to the Owens Corning processes. Contamination, both organic
       and inorganic, including but not limited to * shall be avoided
       throughout the storage, processing, and rail or truck loading of the
       shipment.

       The ore deposit may contain trace amounts of *.  As part of the
       qualification procedure, Owens Corning has measured the level of these
       contaminants * and determined it to be acceptable.  Hereafter, the
       supplier is responsible for measuring the level of * contamination as new
       ore deposits are opened to insure the level has not changed.

C.4    LABORATORY CERTIFICATION
       ------------------------

       The chemical laboratory must be certified by Owens Corning per procedure
       *. Any change in analytical procedure requires re-certification. If the
       supplier does not employ a certified chemical laboratory, then he must
       submit a schedule by which his chemical laboratory will achieve
       certification. This schedule must be mutually agreed upon by the supplier
       and Owens Corning.

C.5    SUPPLY OF TEST DATA
       -------------------

       The supplier shall provide the following data to the Owens Corning user-
       plant on the per shipment basis: * percent retained on the * and *
       sieves, and percent through the * sieve. Oxides and elements designated
       as "*" shall also be provided at the intervals listed in Section C.1.
       Data describing the Chemical and Physical Composition, Section C.1 and
       C.2 respectively, shall be transmitted to the Owens Corning user-plant
       and received prior to unloading.

                     CONFIDENTIAL TREATMENT REQUESTED [*]
<PAGE>

In addition, complete chemistry of * and *, as described in Section C.1, will be
provided to Batch & Melting COE, Granville, Ohio, for the last ten (10) railcars
of each lot and the first ten (10) railcars of each lot.

The "*" are to be obtained from the pre-shipment sample as defined in Section E
(below).  The chemical analyses shall be generated by a laboratory that is
certified by the Analytical Services Laboratory of Owens Corning, as described
in Section C.4.

Control charts for *, as described in Section C.6.2, will be provided to Batch &
Melting COE on a monthly basis.

C.6  TECHNICAL NOTES
     ---------------

     1.   Should long-term production planning indicate a need to shift a target
          nominal, for instance, to optimize reserves or borate lot shipment
          changes, the supplier may propose a change in the specification limits
          for *. The supplier must then propose a target nominal value for the
          oxide(s), and any proposed change must meet the boundary limits beyond
          which no product is acceptable. The change must also meet the limit on
          allowed variation. Those limits are:

                         Boundary Limit  Maximum Range
                         --------------  -------------

          *                     *              *

          The upper specification for the oxide shall be set as the new target
          nominal plus * of the maximum range.  The lower specification limit
          shall be set as the target nominal minus * of the maximum range.  If
          the proposed specification results in a violation of the boundary
          limit listed above, the Batch & Melting COE Laboratory must be
          informed immediately.

          The Batch & Melting COE must be consulted on any proposed change to
          the "Target Nominals" for * before the upper/lower specification
          limits are set.  The new specification will take effect on a date
          mutually acceptable to the supplier and to Batch & Melting COE.

     2.   * is a critical process variable with respect to our manufacturing
          process and our finished glass product. The process capability for
          * must be established and control charts maintained. Any assignable
          causes which result in out-of-control incidents should be investigated
          and appropriate action taken.

     3.   Significant shifts in organic carbon of the finished time product will
          impact the manufacturing process at the Owens Corning user-plant. The

                     CONFIDENTIAL TREATMENT REQUESTED [*]
<PAGE>

          supplier must inform the Owens Corning user-plant when there is a
          change in fuel source within the supplier's manufacturing process.

D.   TEST METHODS
     ------------

     The supplier may use test methods at his discretion provided that they
     yield results which conform to *.  Owens Corning test methods are
     documented in the Manual of Procedures for Glass Control.

E.   PRESHIPMENT SAMPLING
     --------------------

     For each shipment, the supplier shall obtain a representative sample of the
     material directly loaded for shipment or stored in the bin from which the
     shipment was loaded.  A sample library must be maintained for a minimum
     period of 10 weeks.  A representative sample is one which conforms to the
     principles of probability sampling and sample size selection as defined in
     ASTM Methods * and *.  An example of such sampling can be found in ASTM
     Methods *.  At requested frequency, a * gram minimum split of the
     representative sample shall be sent to the Owens Corning user-plant as soon
     as possible after loadout.  If a representative sample is currently
     unobtainable, the supplier shall investigate alternate methods of sampling.

F.   REJECTIONS
     ----------

     Owens Corning reserves the right to reject upon receipt, and hold for
     vendor's disposal, any portion or all of the material furnished under this
     specification which does not conform to all of the requirements set forth
     herein.  Rejection of out-of-specification material will be based solely on
     Owens Corning chemical and physical evaluation.

     Rejection of material based on non-compliance with Section C.1 (CHEMICAL
     COMPOSITION) or Section C.2 (PHYSICAL COMPOSITION) can only be based on
     testing of a representative sample (see Section E above for the definition
     of a representative sample).  If a representative sample is not available
     or cannot be obtained, or if the original representative sample has been
     compromised (i.e. contaminated, lost, etc.), the sample to be used for
     deciding compliance to this specification shall be determined by the Batch
     & Melting COE Laboratory of Owens Corning.

     Non-representative sampling such as grab or visual inspection can be used
     to test conformance to requirements listed in Section C.3 (CONTAMINATION).

G.   SAFETY DOCUMENTATION
     --------------------

     Material Safety Data Sheets shall be supplied to the Owens Corning user-
     plant and the Granville Batch & Melting COE.
