     PURCHASE OPTION 

For the Purchase of up to 

117,500 Shares of Common Stock 

of 

GURUNET CORPORATION 

(A Delaware Corporation) 

1. Purchase Option.

     THIS CERTIFIES THAT, in consideration of $100.00 duly paid by or on behalf of ____________________________ (“Holder”), as registered owner of this Purchase Option, to GuruNet Corporation (“Company”), Holder is entitled, at any time or from time to time at or after ____________ , 2005 (“Commencement Date”), and at or
    before 5:00 p.m., Eastern Time, ____________, 2009 (“Expiration Date”), but not thereafter, to subscribe for, purchase and receive, in whole or in part, up to one hundred seventeen thousand five hundred (117,500) shares of Common
    Stock of the Company, $.001 par value (“Common Stock”) during the period commencing one year and expiring five years from the effective date of the registration statement on Form SB-2 (No. 333-115424) (“Registration Statement”)
    pursuant to which the Company has registered the shares of Common Stock (“Effective Date”). If the Expiration Date is a day on which banking institutions are authorized by law to close, then this Purchase Option may be exercised on the
    next succeeding day which is not such a day in accordance with the terms herein. During the period ending on the Expiration Date, the Company agrees not to take any action that would terminate the Purchase Option. This Purchase Option is initially
    exercisable at $6.25 per share of Common Stock purchased (125% of the initial public offering price per share of Common Stock); provided, however, that upon the occurrence of any of the
    events specified in Section 6 hereof, the rights granted by this Purchase Option, including the exercise price and the number of shares of Common Stock to be received upon such exercise, shall be adjusted as therein specified. The term “Exercise Price” shall mean the initial exercise price or the adjusted exercise price, depending on the context.

2. Exercise. 

     2.1 	Exercise Form. In order to exercise this Purchase Option, the exercise form attached hereto must be duly executed and completed and
delivered to the Company, together with this Purchase Option and payment of the Exercise Price in cash or by certified check or official bank check for the shares of Common Stock being purchased. If the subscription rights represented hereby shall
not be exercised at or before 5:00 p.m., Eastern time, on the Expiration Date, this Purchase Option shall become and be void without further force or effect, and all rights represented hereby shall cease and expire. 

     2.2 	Legend. Each certificate for shares of Common Stock purchased under this Purchase Option shall bear a legend as follows unless such
shares of Common Stock have been registered under the Securities Act of 1933, as amended: 

“The shares of Common Stock represented by this certificate have not been registered under the Securities Act of 1933, as amended (“Act”) or applicable state law. The shares may not be offered for sale, sold or
otherwise transferred except pursuant to an effective registration statement under the Act, or pursuant to an exemption from registration under the Act and applicable state law.” 

     2.3 	Conversion Right. 

          2.3.1 Determination of Amount. In lieu of the payment of the Exercise Price in the manner required by Section 2.1, the Holder shall have the
right (but not the obligation) to convert any exercisable but unexercised portion of this Purchase Option into shares of Common Stock (“Conversion Right”) as follows. Upon exercise of the Conversion Right, the Company shall deliver to the
Holder (without payment by the Holder of any of the Exercise Price in cash) that number of shares of Common Stock equal to the quotient obtained by dividing (x) the “Value” (as defined below), at the close of trading on the next to last
trading day immediately preceding the exercise of the Conversion Right, of the portion of the Purchase Option being converted by (y) the “Market Price” (as defined below). The “Value” of the portion of the Purchase Option being
converted shall equal the remainder derived from subtracting (a) the Exercise Price multiplied by the number of shares of Common Stock underlying that portion of the Purchase Option being converted from (b) the Market Price of the Common Stock
multiplied by the number of shares of Common Stock underlying that portion of the Purchase Option being converted. As used in this herein, the term “Market Price” at any date shall be deemed to be the last reported sale price of the Common
Stock on such date, or, in case no such reported sale takes place on such day, the last reported sale price for the immediately preceding trading day, in either case as officially reported by the principal securities exchange on which the Common
Stock is listed or admitted to trading, or, if the Common Stock is not listed or admitted to trading on any national securities exchange or if any such exchange on which the Common Stock is listed is not its principal trading market, the last
reported sale price as furnished by the NASD through the 

2 

Nasdaq National Market or SmallCap Market, or, if applicable, the OTC Bulletin Board, or if the Common Stock is not listed or admitted to trading on any of the foregoing markets, or similar organization, as determined in good
faith by resolution of the Board of Directors of the Company, based on the best information available to it. 

          2.3.2 Mechanics of Conversion. The Conversion Right may be exercised by the Holder on any business day on or after the Commencement Date and
not later than the Expiration Date by delivering the Purchase Option with a duly executed exercise form attached hereto with the Conversion Right section completed to the Company, exercising the Conversion Right and specifying the total number of
shares of Common Stock that the Holder will purchase pursuant to such Conversion Right. 

3. Transfer. 

     3.1 	General Restrictions. The registered Holder of this Purchase Option, by its acceptance hereof, agrees that it will not sell, transfer or
assign or hypothecate this Purchase Option prior to the Commencement Date to anyone other than (i) an officer or partner of such Holder, (ii) an officer of either Maxim Group LLC or EarlyBirdCapital, Inc., the underwriters of the public offering
with respect to which this Purchase Option has been issued (“Underwriters”) or an officer or partner of any selected dealer in connection with the Company’s public offering with respect to which this Purchase Option has been issued,
or (iii) any selected dealer. On and after the Commencement Date, transfers to others may be made subject to compliance with or exemptions from applicable securities laws. In order to make any permitted assignment, the Holder must deliver to the
Company the assignment form attached hereto duly executed and completed, together with the Purchase Option and payment of all transfer taxes, if any, payable in connection therewith. The Company shall immediately transfer this Purchase Option on the
books of the Company and shall execute and deliver a new Purchase Option or Purchase Options of like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate number of shares of Common Stock purchasable hereunder
or such portion of such number as shall be contemplated by any such assignment. 

     3.2 	Restrictions Imposed by the Act. This Purchase Option and the shares of Common Stock underlying this Purchase Option shall not be
transferred unless and until (i) the Company has received the opinion of counsel for the Holder that this Purchase Option or the shares of Common Stock, as the case may be, may be transferred pursuant to an exemption from registration under the Act
and applicable state law, the availability of which is established to the reasonable satisfaction of the Company (the Company hereby agreeing that an opinion of Graubard Miller shall be deemed satisfactory evidence of the availability of an
exemption), or (ii) a registration statement relating to such Purchase Option or shares of Common Stock, as the case may be, has been filed by the Company and declared effective by the Securities and Exchange Commission and compliance with
applicable state law. 

3 

4. New Purchase Options to be Issued. 

     4.1 	Partial Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase Option may be exercised or assigned in
whole or in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase Option for cancellation, together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price
and/or transfer tax, the Company shall cause to be delivered to the Holder without charge a new Purchase Option of like tenor to this Purchase Option in the name of the Holder evidencing the right of the Holder to purchase the aggregate number of
shares of Common Stock purchasable hereunder as to which this Purchase Option has not been exercised or assigned. 

     4.2 	Lost Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this
Purchase Option and of reasonably satisfactory indemnification, the Company shall execute and deliver a new Purchase Option of like tenor and date. Any such new Purchase Option executed and delivered as a result of such loss, theft, mutilation or
destruction shall constitute a substitute contractual obligation on the part of the Company. 

5. Registration Rights. 

     5.1 	Demand Registration. 

          5.1.1 Grant of Right. The Company, upon written demand (“Initial Demand Notice”) of the Holder(s) of at least 51% of the Purchase
Options and/or the underlying shares of Common Stock (“Majority Holders”), agrees to register on one occasion, all or any portion of the Purchase Options requested by the Majority Holders in the Initial Demand Notice and all of the shares
of Common Stock underlying such Purchase Options (collectively the “Registrable Securities”). On such occasion, the Company will file a registration statement covering the Registrable Securities within sixty (60) days after receipt of the
Initial Demand Notice and use its best efforts to have the registration statement declared effective promptly thereafter. If the Company fails to comply with the provisions of this Section 5.1.1, the Company shall, in addition to any other equitable
or other relief available to the Holder(s), be liable for any and all incidental, special and consequential damages sustained by the Holder(s). The demand for registration may be made at any time during a period of four years beginning one year from
the Effective Date. The Company covenants and agrees to give written notice of its receipt of any Initial Demand Notice by any Holder(s) to all other registered Holders of the Purchase Options and/or the Registrable Securities within ten days from
the date of the receipt of any such Initial Demand Notice. 

          5.1.2 Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities, but the Holders shall pay any
and all underwriting commissions and the expenses of any legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities. The Company agrees to use its reasonable 

4 

best efforts to cause the filing required herein to become effective promptly and to qualify or register the Registrable Securities in such States as are reasonably requested by the Holder(s); provided, however, that in no event
shall the Company be required to register the Registrable Securities in a State in which such registration would cause (i) the Company to be obligated to register or license to do business in such State or submit to general service of process in
such State, or (ii) the principal stockholders of the Company to be obligated to escrow their shares of capital stock of the Company. The Company shall cause any registration statement filed pursuant to the demand right granted under Section 5.1.1
to remain effective for a period of at least twelve consecutive months from the date that the Holders of the Registrable Securities covered by such registration statement are first given the opportunity to sell all of such securities. 

     5.2 	“Piggy-Back” Registration. 

          5.2.1 Grant of Right. In addition to the demand right of registration, the Holders of the Purchase Options shall have the right for a period
of six (6) years commencing one year from the Effective Date, to include the Registrable Securities as part of any other registration of securities filed by the Company (other than in connection with a transaction contemplated by Rule 145(a)
promulgated under the Act or pursuant to Form S-8 or any equivalent form); provided, however, that if, in the written determination of the Company’s managing underwriter or underwriters, if any, for such offering, the inclusion of the
Registrable Securities, when added to the securities being registered by the Company or the selling stockholder(s), will exceed the maximum amount of the Company’s securities which can be marketed (i) at a price reasonably related to their then
current market value, or (ii) without materially and adversely affecting the entire offering, the Company shall nevertheless register all or any portion of the Registrable Securities required to be so registered but such Registrable Securities shall
not be sold by the Holders until 90 days after the registration statement for such offering has become effective and provided further that, if any securities are registered for sale on behalf of other stockholders in such offering and such
stockholders have not agreed to defer such sale until the expiration of such 90 day period, the number of securities to be sold by all stockholders in such public offering during such 90 day period shall be apportioned pro rata among all such selling stockholders, including all holders of the Registrable Securities, according to the total amount of securities of
the Company owned by said selling stockholders, including all holders of the Registrable Securities. 

          5.2.2 Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities, but the Holders shall pay any
and all underwriting commissions and the expenses of any legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities. In the event of such a proposed registration, the Company shall furnish the
then Holders of outstanding Registrable Securities with not less than thirty (30) days written notice prior to the proposed date of filing of such registration statement. Such notice to the Holders shall continue to be given for each registration
statement filed by the Company until such time as all of the Registrable Securities have been sold by the Holder. The holders of the Registrable Securities shall exercise the “piggy-back” rights 

5 

provided for herein by giving written notice, within twenty (20) days of the receipt of the Company’s notice of its intention to file a registration statement. The Company shall cause any registration statement filed pursuant
to the above “piggyback” rights to remain effective for at least twelve months from the date that the Holders of the Registrable Securities are first given the opportunity to sell all of such securities. 

     5.3 	General Terms.

          5.3.1 Indemnification. The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration
statement hereunder and each person, if any, who controls such Holders within the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange Act of 1934, as amended (“Exchange Act”), against all loss, claim, damage,
expense or liability (including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which any of them may become subject under the Act, the Exchange Act
or otherwise, arising from such registration statement but only to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify the Underwriters contained in Section 5 of the Underwriting Agreement
between the Underwriters and the Company, dated the Effective Date. The Holder(s) of the Registrable Securities to be sold pursuant to such registration statement, and their successors and assigns, shall severally, and not jointly, indemnify the
Company, against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which they may become
subject under the Act, the Exchange Act or otherwise, arising from information furnished by or on behalf of such Holders, or their successors or assigns, in writing, for specific inclusion in such registration statement to the same extent and with
the same effect as the provisions contained in Section 5 of the Underwriting Agreement pursuant to which the Underwriters have agreed to indemnify the Company. 

          5.3.2 Exercise of Purchase Options. Nothing contained in this Purchase Option shall be construed as requiring the Holder(s) to exercise their
Purchase Options prior to or after the initial filing of any registration statement or the effectiveness thereof. 

          5.3.3 Documents Delivered to Holders. The Company shall furnish to each Holder participating in any of the foregoing offerings and to each
underwriter of any such offering, if any, a signed counterpart, addressed to such Holder or underwriter, of (i) an opinion of counsel to the Company, dated the effective date of such registration statement (and, if such registration includes an
underwritten public offering, an opinion dated the date of the closing under any underwriting agreement related thereto), and (ii) a “cold comfort” letter dated the effective date of such registration statement (and, if such registration
includes an underwritten public offering, a letter dated the date of the closing under the underwriting agreement) signed by the independent public accountants who have issued a report on the Company’s financial statements included in such
registration statement, in each case covering substantially the same 

6 

matters with respect to such registration statement (and the prospectus included therein) and, in the case of such accountants’ letter, with respect to events subsequent to the date of such financial statements, as are
customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to underwriters in underwritten public offerings of securities. The Company shall also deliver promptly to each Holder participating in the offering
requesting the correspondence and memoranda described below and to the managing underwriter copies of all correspondence between the Commission and the Company, its counsel or auditors and all memoranda relating to discussions with the Commission or
its staff with respect to the registration statement and permit each Holder and underwriter to do such investigation, upon reasonable advance notice, with respect to information contained in or omitted from the registration statement as it deems
reasonably necessary to comply with applicable securities laws or rules of the National Association of Securities Dealers, Inc. (“NASD”). Such investigation shall include access to books, records and properties and opportunities to discuss
the business of the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable times as any such Holder shall reasonably request. 

          5.3.4 Underwriting Agreement. The Company shall enter into an underwriting agreement with the managing underwriter(s) selected by any Holders
whose Registrable Securities are being registered pursuant to this Section 5, which managing underwriter shall be reasonably satisfactory to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company, each
Holder and such managing underwriters, and shall contain such representations, warranties and covenants by the Company and such other terms as are customarily contained in agreements of that type used by the managing underwriter. The Holders shall
be parties to any underwriting agreement relating to an underwritten sale of their Registrable Securities and may, at their option, require that any or all the representations, warranties and covenants of the Company to or for the benefit of such
underwriters shall also be made to and for the benefit of such Holders. Such Holders shall not be required to make any representations or warranties to or agreements with the Company or the underwriters except as they may relate to such Holders,
their shares and their intended methods of distribution. 

          5.3.5 Documents to be Delivered by Holder(s). Each of the Holder(s) participating in any of the foregoing offerings shall furnish to the
Company a completed and executed questionnaire provided by the Company requesting information customarily sought of selling securityholders. 

6. Adjustments. 

     6.1 	Adjustments to Exercise Price and Number of Securities. The Exercise Price and the number of shares of Common Stock underlying the
Purchase Option shall be subject to adjustment from time to time as hereinafter set forth: 

          6.1.1 Stock Dividends - Recapitalization, Reclassification, Split-Ups. If after the date hereof, and subject to the provisions of Section 6.2
below, the number of outstanding 

7 

shares of Common Stock is increased by a stock dividend payable in shares of Common Stock or by a split-up, recapitalization or reclassification of shares of Common Stock or other similar event, then, on the effective date
thereof, the number of shares of Common Stock issuable on exercise of the Purchase Option shall be increased in proportion to such increase in outstanding shares of Common Stock. 

          6.1.2 Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 6.2, the number of outstanding shares of
Common Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock or other similar event, then, upon the effective date thereof, the number of shares of Common Stock issuable on exercise of the Purchase Option
shall be decreased in proportion to such decrease in outstanding shares. 

          6.1.3 Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of this Purchase Option is
adjusted, as provided in this Section 6.1, the Exercise Price shall be adjusted (to the nearest cent) by multiplying such Exercise Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of
Common Stock purchasable upon the exercise of this Purchase Option immediately prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.

          6.1.4 Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of
Common Stock other than a change covered by Section 6.1.1 hereof or which solely affects the par value of such shares of Common Stock, or in the case of any merger or consolidation of the Company with or into another corporation (other than a
consolidation or merger in which the Company is the continuing corporation and which does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another
corporation or entity of the property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Option shall have the right thereafter (until the expiration of the
right of exercise of this Purchase Option) to receive upon the exercise hereof, for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of shares of stock or other securities or property
(including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or other transfer, by a Holder of the number of shares of Common Stock of the Company obtainable upon
exercise of this Purchase Option immediately prior to such event; and if any reclassification also results in a change in shares of Common Stock covered by Section 6.1.1, then such adjustment shall be made pursuant to Sections 6.1.1, 6.1.3 and this
Section 6.1.4. The provisions of this Section 6.1.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. 

          6.1.5 Changes in Form of Purchase Option. This form of Purchase Option need not be changed because of any change pursuant to this Section,
and Purchase Options issued after 

8 

such change may state the same Exercise Price and the same number of shares of Common Stock as are stated in the Purchase Options initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of new
Purchase Options reflecting a required or permissive change shall not be deemed to waive any rights to a prior adjustment or the computation thereof. 

     6.2 	Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of shares of Common
Stock upon the exercise or transfer of the Purchase Option, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any
fraction up or down to the nearest whole number of shares of Common Stock. 

7. 	Reservation and Listing. The Company shall at all times reserve and keep available out of its authorized shares of Common Stock, solely for the purpose of issuance
upon exercise of the Purchase Options, such number of shares of Common Stock or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Purchase Options and
payment of the Exercise Price therefor, all shares of Common Stock and other securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any stockholder. As long as
the Purchase Options shall be outstanding, the Company shall use its best efforts to cause all shares of Common Stock issuable upon exercise of the Purchase Options to be listed (subject to official notice of issuance) on all securities exchanges
(or, if applicable on Nasdaq) on which the Common Stock issued to the public in connection herewith are then listed and/or quoted. 

8. Certain Notice Requirements. 

     8.1 	Holder’s Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent or
to receive notice as a stockholder for the election of directors or any other matter, or as having any rights whatsoever as a stockholder of the Company. If, however, at any time prior to the expiration of the Purchase Options and their exercise,
any of the events described in Section 8.2 shall occur, then, in one or more of said events, the Company shall give written notice of such event at least fifteen (15) days prior to the date fixed as a record date or the date of closing the transfer
books for the determination of the stockholders entitled to such dividend, distribution, conversion or exchange of securities or subscription rights, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice
shall specify such record date or the date of the closing of the transfer books, as the case may be.

     8.2 	Events Requiring Notice. The Company shall be required to give the notice described in this Section 8 upon one or more of the following
events: (i) if the Company shall take a record of the holders of its shares of Common Stock for the purpose of entitling them to receive a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise
than out of retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company, or (ii) the Company 

9 

shall offer to all the holders of its Common Stock any additional shares of capital stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to
subscribe therefor, or (iii) a dissolution, liquidation or winding up of the Company (other than in connection with a consolidation or merger) or a sale of all or substantially all of its property, assets and business shall be proposed. 

     8.3 	Notice of Change in Exercise Price. The Company shall, promptly after an event requiring a change in the Exercise Price pursuant to
Section 6 hereof, send notice to the Holders of such event and change (“Price Notice”). The Price Notice shall describe the event causing the change and the method of calculating same and shall be certified as being true and accurate by
the Company’s President and Chief Financial Officer. 

     8.4 	Transmittal of Notices. All notices, requests, consents and other communications under this Purchase Option shall be in writing and
shall be deemed to have been duly made on the date of delivery if delivered personally or sent by overnight courier, with acknowledgement of receipt to the party to which notice is given, or on the fifth day after mailing if mailed to the party to
whom notice is to be given, by registered or certified mail, return receipt requested, postage prepaid and properly addressed as follows: (i) if to the registered Holder of the Purchase Option, to the address of such Holder as shown on the books of
the Company, or (ii) if to the Company, to its principal executive office. 

9. Miscellaneous. 

     9.1 	Amendments. The Company and the Underwriters may from time to time supplement or amend this Purchase Option without the approval of any
of the Holders in order to cure any ambiguity, to correct or supplement any provision contained herein which may be defective or inconsistent with any other provisions herein, or to make any other provisions in regard to matters or questions arising
hereunder which the Company and the Underwriters may deem necessary or desirable and which the Company and the Underwriters deem shall not adversely affect the interest of the Holders. All other modifications or amendments shall require the written
consent of the party against whom enforcement of the modification or amendment is sought. 

     9.2 	Headings. The headings contained herein are for the sole purpose of convenience of reference, and shall not in any way limit or affect
the meaning or interpretation of any of the terms or provisions of this Purchase Option. 

     9.3 	Entire Agreement. This Purchase Option (together with the other agreements and documents being delivered pursuant to or in connection
with this Purchase Option) constitutes the entire agreement of the parties hereto with respect to the subject matter hereof, and supersedes all prior agreements and understandings of the parties, oral and written, with respect to the subject matter
hereof. 

10 

     9.4 	Binding Effect. This Purchase Option shall inure solely to the benefit of and shall be binding upon, the Holder and the Company and
their respective successors, legal representatives and assigns, and no other person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this Purchase Option or any provisions herein
contained. 

     9.5 	Governing Law; Submission to Jurisdiction. This Purchase Option shall be governed by and construed and enforced in accordance with the
laws of the State of New York, without giving effect to conflict of laws. The Company hereby agrees that any action, proceeding or claim against it arising out of, or relating in any way to this Purchase Option shall be brought and enforced in the
courts of the State of New York or of the United States of America for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives any objection to such exclusive
jurisdiction and that such courts represent an inconvenient forum. Any process or summons to be served upon the Company may be served by transmitting a copy thereof by registered or certified mail, return receipt requested, postage prepaid,
addressed to Greenberg Traurig, LLP, 200 Park Avenue, 15th Floor, New York, New York 10166, Attention: Robert H. Cohen, Esq. Such mailing shall be deemed personal service and shall be
legal and binding upon the Company in any action, proceeding or claim. The Company and the Holder, by acceptance hereof, agree that the prevailing party(ies) in any such action shall be entitled to recover from the other party(ies) all of its
reasonable attorneys’ fees and expenses relating to such action or proceeding and/or incurred in connection with the preparation therefor. 

     9.6 	Waiver, Etc. The failure of the Company or the Holder to at any time enforce any of the provisions of this Purchase Option shall not be
deemed or construed to be a waiver of any such provision, nor to in any way affect the validity of this Purchase Option or any provision hereof or the right of the Company or any Holder to thereafter enforce each and every provision of this Purchase
Option. No waiver of any breach, non-compliance or non-fulfillment of any of the provisions of this Purchase Option shall be effective unless set forth in a written instrument executed by the party or parties against whom or which enforcement of
such waiver is sought; and no waiver of any such breach, non-compliance or non-fulfillment shall be construed or deemed to be a waiver of any other or subsequent breach, non-compliance or non-fulfillment.

                  If and when issued, Exchange Securities offered to Holders, as

shall be deposited on behalf of the Holders of the Exchange Securities
represented thereby with the Trustee, as custodian for the Depositary, and
registered in the name of the Depositary or its nominee, as the case may be,
duly executed by the Company and authenticated by the Trustee (or an
authenticating agent appointed by the Trustee in accordance with Section 2.02)
as hereinafter provided. The aggregate principal amount of the Exchange Global
Security may from time to time be increased or decreased by adjustments made by
the Registrar on Schedule A to the Exchange Global Security and recorded in the
Security Register, as hereinafter provided.

                  Upon the transfer, exchange or replacement of any Initial
Security or Additional Security, as applicable, if any Initial Security or
Additional Security, as applicable, shall remain outstanding after the
consummation of an Exchange Offer, the Registrar shall deliver such Initial
Security or Additional Security, as applicable, only in global form, subject to
Section 2.06(a), and such Initial Security or Additional Security, as
applicable, shall continue to bear the applicable legends set forth in Exhibit C
hereto. In the case of a Restricted Global Security, such legends shall include
the applicable Private Placement Legend unless (x) the appropriate period
referred to in Rule 144(k) under the Securities Act has elapsed or (y) there is
delivered to the Registrar an opinion of counsel reasonably satisfactory to the
Company to the effect that neither such legend nor the related restrictions on
transfer are required in order to maintain compliance with the Securities Act.

                  Upon the transfer, exchange or replacement of any Security
pursuant to a Shelf Registration Statement, the Registrar shall deliver such new
Security only in global form, and such new Security shall be substantially in

consummated, or upon the subsequent consummation of an Exchange Offer,
beneficial interests in any such new Security shall be reflected in the Exchange
Global Security.

apply to the Restricted Global Security, the Temporary Regulation S Global

and, if and when issued, the Exchange Global Security (collectively, the "GLOBAL
SECURITIES") deposited with or on behalf of the Depositary.

                  Except as provided in Section 2.06(a), Participants shall have
no rights under this Indenture with respect to any Global Security held on their
behalf by the Depositary or by the Trustee or any custodian of the Depositary or
under such Global Security, and the Depositary or its nominee, as the case may
be, may be treated by the Company, a Guarantor, the Trustee and any agent of the
Company, a Guarantor or the Trustee as the sole owner of such Global Security
for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall
prevent the Company, a Guarantor, the Trustee or any agent of the Company, a
Guarantor or the Trustee from giving effect to any written certification, proxy
or other authorization furnished by the Depositary or impair, as between the
Depositary and its Participants, the operation of customary practices of such
persons governing the exercise of the rights of a Holder of a beneficial
interest in any Global Security.

                  The registered Holder of a Global Security may grant proxies
and otherwise authorize any Person, including Participants and Persons that may
hold interests through Participants, to take any action that a Holder is
entitled to take under this Indenture, the Securities or the Subsidiary
Guarantees.

                  Except as otherwise provided in this Indenture or, with
respect to the Company or a Guarantor, as otherwise provided in any agreement
between the Company or a Guarantor and a registered holder of a Global Security
or its agents, none of the Company, a Guarantor, the Trustee nor any agent of
the Company, a Guarantor or the Trustee shall have any responsibility or
liability for any aspect of the records of a registered holder of a Global
Security relating to beneficial ownership interests of such Global Security.

                  Except as provided in Section 2.06(a), owners of a beneficial
interest in Global Securities will not be entitled to receive physical delivery
of certificated Securities.

                  Section 2.02. EXECUTION AND AUTHENTICATION; AGGREGATE
PRINCIPAL AMOUNT. Two Officers shall sign the Securities for the Company by
facsimile or manual signature.

                  If a Person whose signature is on a Security as an Officer no
longer holds that office or position at the time the Trustee authenticates the
Security, the Security shall be valid nevertheless.

                  A Security shall not be valid until the Trustee manually signs
the certificate of authentication on the Security. The signature shall be
conclusive evidence that the Security has been authenticated under this
Indenture.

                  The Trustee shall authenticate and make available for delivery
7.75% Senior Notes due 2014 of the Company for original issue in an aggregate
principal amount of $200,000,000 (the "INITIAL SECURITIES") for original issue
on the Issue Date upon a written order of the Company signed by an Officer of
the Company to a Trust Officer. Subject to Section 4.09 and as long as permitted
under the other provisions of this Indenture, the Company may issue after the
Issue Date, and the Trustee shall authenticate, (1) additional 7.75% Senior
Notes due 2014 of the Company (the "ADDITIONAL SECURITIES") in an unlimited
amount for original issue and

                                       23
<PAGE>

(2) Series B 7.75% Senior Notes due 2014 of the Company (the "EXCHANGE
SECURITIES") from time to time for issue only in exchange for a like principal
amount of Initial Securities and Additional Securities exchanged in an Exchange
Offer in accordance with the applicable Registration Rights Agreement, in each
case upon a written order of the Company signed by an Officer of the Company to
a Trust Officer. Each such written order shall specify the amount of Securities
to be authenticated, the date on which the Securities are to be authenticated
and whether the Securities are to be Initial Securities, Additional Securities
or Exchange Securities.

                  The Trustee may appoint an authenticating agent acceptable to
the Company to authenticate the Securities, which authenticating agent shall be
compensated by the Company. Unless limited by the terms of such appointment, an
authenticating agent may authenticate Securities whenever the Trustee may do so,
except with regard to the original issuance of the Securities and pursuant to
Section 2.06. Except as provided in the preceding sentence, each reference in
this Indenture to authentication by the Trustee includes authentication by such
agent. An authenticating agent has the same rights as any Agent.

                  Section 2.03. REGISTRAR, TRANSFER AGENT AND PAYING AGENT. The
Company shall maintain an office or agency where Securities may be presented or
surrendered for registration of transfer or for exchange ("REGISTRAR"), an
office or agency where the Securities may be transferred or exchanged (the
"TRANSFER AGENT"), an office or agency where Securities may be presented for
payment ("PAYING AGENT") and an office or agency where notices or demands to or
upon the Company in respect of the Securities may be served. The Company may
have one or more co-Registrars, one or more Transfer Agents and one or more
additional Paying Agents. The term "Paying Agent" includes any additional Paying
Agent.

                  Subject to any applicable laws and regulations, the Company
shall cause the Registrar to keep a register (the "SECURITY REGISTER") at its
Corporate Trust Office in which, subject to such reasonable regulations it may
prescribe, the Company shall provide for the registration of ownership,
exchange, and transfer of the Securities. Such registration in the Security
Register shall be conclusive evidence of the ownership of Securities. Included
in the books and records for the Securities shall be notations as to whether
such Securities have been paid, exchanged or transferred, canceled, lost,
stolen, mutilated or destroyed and whether such Securities have been replaced.
In the case of the replacement of any of the Securities, the Registrar shall
keep a record of the Security so replaced and the Security issued in replacement
thereof. In the case of the cancellation of any of the Securities, the Registrar
shall keep a record of the Security so canceled and the date on which such
Security was canceled.

                  The Company shall enter into an appropriate written agency
agreement with any Agent not a party to this Indenture, which shall incorporate
the terms of the TIA. Each such agreement shall implement the provisions of this
Indenture that relate to such Agent. The Company shall give prompt written
notice to the Trustee of the name and address of any such Agent and any change
in the address of such Agent. The Company may change an Agent without prior
notice to the Holders. In the event that there is a change in the address of an
Agent or if the Company changes an Agent, the Company shall promptly notify the
Holders in writing. If the Company fails to maintain a Registrar, Transfer Agent
or Paying Agent, the Trustee shall act as such.

                                       24
<PAGE>

                  The Company initially appoints the Trustee as Registrar,
Transfer Agent and Paying Agent in connection with the Securities.

                  Section 2.04. PAYING AGENT TO HOLD MONEY IN TRUST. The Company
shall require each Paying Agent other than the Trustee to agree in writing that
such Paying Agent shall hold in trust for the benefit of Securityholders all
money held by the Paying Agent for the payment of principal of or interest on
the Securities, and such Paying Agent shall notify the Trustee of any default by
the Company in making any such payment. If the Company or any of its
Subsidiaries acts as Paying Agent, it shall segregate the money and hold it as a
separate trust fund. The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee and account for any funds disbursed, and the
Trustee may at any time during the continuance of any payment default, upon
written request to a Paying Agent, require such Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed. Upon doing so,
the Paying Agent shall have no further liability for the money so paid over to
the Trustee.

                  Section 2.05. SECURITYHOLDER LISTS. The Trustee shall preserve
in as current a form as is reasonably practicable the most recent list available
to it of the names and addresses of Securityholders and shall otherwise comply
with TIA ss. 312(a). If the Trustee is not the Registrar, the Company shall
furnish to the Trustee at least ten Business Days before each Interest Payment
Date but not later than the Record Date for such Interest Payment Date, if such
date is earlier, and at such other times as the Trustee may request in writing a
list in such form and as of such date as the Trustee may reasonably require of
the names and addresses of Securityholders, and the Company shall otherwise
comply with TIA ss. 312(a).

                  The Trustee shall be entitled to rely upon a certificate of
the Registrar, the Company or such other Paying Agent, as the case may be, as to
the names and addresses of the Securityholders and the principal amounts and
serial numbers of the Securities.

                  Section 2.06. TRANSFER AND EXCHANGE. (a) Where Securities are
presented to the Registrar or a co-Registrar with a request to register a
transfer or to exchange them for an equal principal amount of Securities of
other denominations, the Registrar shall register the transfer or make the
exchange in accordance with the requirements of this Section 2.06. To permit
registrations of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Securities, of any authorized denominations and
of a like aggregate principal amount, at the Registrar's request.

                  Upon presentation for exchange or transfer of any Security as
permitted by the terms of this Indenture and by any legend appearing on such
Security, such Security shall be exchanged or transferred upon the Security
Register and one or more new Securities shall be authenticated and issued in the
name of the Holder (in the case of exchanges only) or the transferee, as the
case may be. No exchange or transfer of a Security shall be effective under this
Indenture unless and until such Security has been registered in the name of such
Person in the Security Register. Furthermore, the exchange or transfer of any
Security shall not be effective under this Indenture unless the request for such
exchange or transfer is made by the Holder or by a duly authorized
attorney-in-fact at the office of the Registrar.

                                       25
<PAGE>

                  Every Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Registrar)
be duly endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Company and the Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing.

                  All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company evidencing
the same indebtedness, and entitled to the same benefits under this Indenture,
as the Securities surrendered upon such registration of transfer or exchange.

                  In the event that the Company delivers to the Trustee a copy
of an Officers' Certificate certifying that an Exchange Offer Registration
Statement or a Shelf Registration Statement, as the case may be, has been
declared effective by the Commission, and that the Company has offered Exchange
Securities to the Holders in accordance with the Exchange Offer or that
Securities have been offered pursuant to such Shelf Registration Statement, the
Trustee shall exchange or issue upon transfer, as the case may be, upon request
of any Holder, such Holder's Securities for (i) in the case of an Exchange
Offer, Exchange Securities upon the terms set forth in the Exchange Offer or
(ii) in the case of a transfer pursuant to a Shelf Registration Statement,
Securities that comply with the requirements applicable following such a
transfer as set forth in Section 2.06(b).

                  No service charge to the Securityholder shall be made for any
registration of transfer or exchange, but the Company or the Trustee may require
from the transferring or exchanging Securityholder payment of a sum sufficient
to cover any transfer tax or similar governmental charge payable in connection
therewith (other than any such transfer taxes or similar governmental charge
payable upon exchanges pursuant to Sections 2.10, 3.06, 4.14, 4.15 or 9.05). The
Registrar or co-Registrar shall not be required to register the transfer of or
exchange of any Security (i) during a period beginning at the opening of
business 15 days before the mailing of a notice of redemption of Securities and
ending at the close of business on the day of such mailing and (ii) selected for
redemption in whole or in part pursuant to Article III, except the unredeemed
portion of any Security being redeemed in part.

                  If a Security is a Restricted Security in certificated form,
then as provided in this Indenture and subject to the limitations herein set
forth, the Holder, provided it is a Qualified Institutional Buyer, an Accredited
Investor or a Holder pursuant to Regulation S, may exchange such Security for a
Book-Entry Security by instructing the Trustee to arrange for such Security to
be represented by a beneficial interest in a Global Security in accordance with
the customary procedures of the Depositary.

                  In accordance with the provisions of this Indenture and
subject to Section 2.06(b)(viii) and certain limitations herein set forth, an
owner of a beneficial interest in a Global Security which has not been exchanged
for an Exchange Security may request a Security in certificated form, in
exchange in whole or in part, as the case may be, for such beneficial owner's
interest in the Global Security.

                  Notwithstanding the foregoing, no Global Security shall be

by the Company within 90 days, (ii) the Company executes and delivers to the
Trustee a Company order that all such Global Securities shall be exchangeable or

preceding sentence, such Global Security may be registered for transfer or
exchange for Securities registered in the names of, authenticated and delivered

                  Except as provided above and in section 2.06(b)(viii), any
Security authenticated and delivered upon registration of transfer of, or in
exchange for, or in lieu of, any Global Security, whether pursuant to this
Section 2.06, Section 2.07, 2.10 or 3.06 or otherwise, shall also be a Global
Security and bear the applicable legend specified in Exhibit A or B, as
applicable.

                  The Company shall not have any liability to any Person
relating to (i) the performance by the Depositary, Euroclear, Clearstream or any
of their respective direct or indirect Participants under the Applicable Rules,
or (ii) maintaining, supervising or reviewing any records of such entities
relating to the Securities.

                  (b)      Notwithstanding any provision to the contrary herein,
so long as a Global Security remains outstanding and is held by or on behalf of
the Depositary, transfers of a Global Security, in whole or in part, or of any
beneficial interest therein, shall only be made in accordance with Section
2.06(a) and this Section 2.06(b); PROVIDED, HOWEVER, that a beneficial interest
in a Global Security may be transferred to Persons who take delivery thereof in
the form of a beneficial interest in the same Global Security in accordance with
the transfer restrictions set forth in the restricted Security legend on the
Security, if any and the Trustee shall have no responsibility with respect to
any such transfers.

                  (i)      Except for transfers or exchanges made in accordance
         with any of clauses (ii), (iii), (iv), (v), (vi), (vii) or (viii) of
         this Section 2.06(b), transfers of a Global Security shall be limited
         to transfers of such Global Security in whole, but not in part, to the
         Depositary, to nominees of the Depositary or to a successor of the
         Depositary or such successor's nominee.

                  (ii)     TEMPORARY REGULATION S GLOBAL SECURITY. If the Holder
         of a beneficial interest in the Temporary Regulation S Global Security
         at any time wishes to transfer its interest in such Temporary
         Regulation S Global Security to a Person who wishes to take delivery
         thereof in the form of a beneficial interest in the Temporary
         Regulation S Global Security, such transfer or exchange may be effected
         only in accordance with this clause (ii) and the Applicable Procedures.
         Upon (A) delivery by a beneficial owner of an interest therein to
         Euroclear or Clearstream (as the case may be) of a written
         certification substantially in the form of Exhibit D-1 hereto, and (B)
         delivery by the transferee of such interest to Euroclear or Clearstream
         (as the case may be) of a written certification

<PAGE>

         substantially in the form of Exhibit D-2 hereto, then Euroclear or
         Clearstream, as the case may be, shall reflect on its records the
         transfer of a beneficial interest in the Temporary Regulation S Global
         Security from the beneficial owner providing the certification provided
         in (A) above to the Person providing the certification provided in (B)
         above.

                  (iii)    TEMPORARY REGULATION S GLOBAL SECURITY TO REGULATION
         S GLOBAL SECURITY. If the Holder of a beneficial interest in the
         Temporary Regulation S Global Security at any time, on or after the

         transfer its interest in such Temporary Regulation S Global Security to
         a Person who wishes to take delivery thereof in the form of a
         beneficial interest in the Regulation S Global Security, such transfer
         or exchange may be effected only in accordance with this clause (iii)
         and the Applicable Procedures. Upon (A) delivery by a beneficial owner
         of an interest therein to Euroclear or Clearstream (as the case may be)
         of a written certification substantially in the form of Exhibit D-1
         hereto, and (B) delivery by Euroclear or Clearstream to the Trustee and
         Transfer Agent of a written certification substantially in the form
         attached hereto as Exhibit E, and (C) receipt by the Trustee, as
         Registrar, from the Transfer Agent of the written certification
         described in (B) and of instructions directing the Trustee, as
         Registrar, to credit or cause to be credited an interest in the
         Regulation S Global Security in a specified principal amount and to
         cause to be debited an interest in the Temporary Regulation S Global
         Security in such specified principal amount, then the Registrar shall
         instruct the Depositary to reduce or cause to be reduced the principal
         amount of the Temporary Regulation S Global Security and to increase or
         cause to be increased the principal amount of the Regulation S Global
         Security by the aggregate principal amount of the beneficial interest
         in such Temporary Regulation S Global Security to be so exchanged or
         transferred, and to credit or cause to be credited to the account of
         the Person specified in such instructions a beneficial interest in the
         Regulation S Global Security having a principal amount equal to the
         principal amount by which the amount of the Temporary Regulation S
         Global Security was reduced upon such exchange or transfer.

                  (iv)     RESTRICTED GLOBAL SECURITY TO REGULATION S GLOBAL
         SECURITY. If the Holder of a beneficial interest in the Restricted
         Global Security at any time wishes to exchange its interest in such
         Restricted Global Security for an interest in the Regulation S Global
         Security, or to transfer its interest in such Restricted Global
         Security to a Person who wishes to take delivery thereof in the form of
         a beneficial interest in the Regulation S Global Security, such
         transfer or exchange may be effected only in accordance with this
         clause (iv) and the Applicable Procedures. Upon receipt by the
         Registrar of (A) instructions given in accordance with the Applicable
         Procedures directing the Registrar to credit or cause to be credited an
         interest in the Regulation S Global Security in a specified principal
         amount and to cause to be debited an interest in the Restricted Global
         Security in such specified principal amount, and (B) a certificate in
         the form of Exhibit F attached hereto given by the Holder of such
         beneficial interest stating that the transfer of such interest has been
         made in compliance with the transfer restrictions applicable to the
         Global Securities and (x) pursuant to and in accordance with Regulation
         S or (y) that the Security being transferred is being transferred in a
         transaction permitted by Rule 144,

                                       28
<PAGE>

         then the Registrar shall instruct the Depositary to reduce or cause to
         be reduced the principal amount of the Restricted Global Security and
         to increase or cause to be increased the principal amount of the
         Regulation S Global Security by the aggregate principal amount of the
         interest in the Restricted Global Security to be exchanged or
         transferred, and to credit or cause to be credited to the account of

         principal amount by which the amount of the Restricted Global Security
         was reduced upon such exchange or transfer.

                  (v)      TEMPORARY REGULATION S GLOBAL SECURITY OR REGULATION
         S GLOBAL SECURITY TO RESTRICTED GLOBAL SECURITY. If the Holder of a
         beneficial interest in the Temporary Regulation S Global Security or
         the Regulation S Global Security at any time wishes to exchange its
         interest in the Regulation S Global Security for an interest in the
         Restricted Global Security, or to transfer such interest to a Person
         who wishes to take delivery thereof in the form of a beneficial
         interest in the Restricted Global Security such transfer may be
         effected only in accordance with this clause (v) and the Applicable
         Procedures. Upon receipt by the Registrar of (A) instructions given in
         accordance with the Applicable Procedures directing the Registrar to
         credit or cause to be credited an interest in the Restricted Global
         Security in a specified principal amount and to cause to be debited an
         interest in the Temporary Regulation S Global Security or the
         Regulation S Global Security, as the case may be, in such specified
         principal amount, and (B) a certificate in the form of Exhibit G
         attached hereto given by the Holder of such beneficial interest stating
         that the transfer of such interest has been made in compliance with the
         transfer restrictions applicable to the Global Securities and stating
         that (x) the Person transferring such Interest reasonably believes that
         the Person acquiring such interest is a QIB and is obtaining such
         interest in a transaction meeting the requirements of Rule 144A and any
         applicable securities laws of any state of the United States or (y)
         that the Person transferring such interest is relying on an exemption
         other than Rule 144A from the registration requirements of the
         Securities Act and, in such circumstances, such opinion of counsel as
         the Company may reasonably request to ensure that the requested
         transfer or exchange is being made pursuant to an exemption from, or in
         a transaction not subject to, the registration requirements of the
         Securities Act, then the Registrar shall instruct the Depositary to
         reduce or cause to be reduced the principal amount of the Temporary
         Regulation S Global Security or the Regulation S Global Security, as
         the case may be, and to increase or cause to be increased the principal
         amount of the Restricted Global Security by the aggregate principal
         amount of the interest in the Temporary Regulation S Global Security or
         the Regulation S Global Security, as the case may be, to be exchanged
         or transferred, and to credit or cause to be credited to the account of
         the Person specified in such instructions a beneficial interest in the
         Restricted Global Security having a principal amount equal to the
         principal amount by which the amount of the Temporary Regulation S
         Global Security or the Regulation S Global Security, as the case may
         be, was reduced upon such exchange or transfer.

                  (vi)     RESTRICTED GLOBAL SECURITY TO EXCHANGE GLOBAL
         SECURITY. Following the earlier of the consummation of the Exchange
         Offer or the transfer of a Security pursuant to a Shelf Registration
         Statement that results in beneficial interests in such Security being
         reflected in the Exchange Global Security, if the Holder of a
         beneficial interest in the

                                       29
<PAGE>

         Restricted Global Security at any time wishes to exchange its interest
         in such Restricted Global Security for an interest in the Exchange
         Global Security, or to transfer its interest in such Restricted Global
         Security to a Person who wishes to take delivery thereof in the form of
         a beneficial interest in the Exchange Global Security, such transfer or
         exchange, if not effected pursuant to Section 2.06(a), may be effected
         only in accordance with this clause (vi) and the Applicable Procedures.
         Upon receipt by the Registrar of (A) instructions given in accordance
         with the Applicable Procedures directing the Registrar to credit or
         cause to be credited an interest in the Exchange Global Security in a
         specified principal amount and to cause to be debited an interest in
         the Restricted Global Security in such specified principal amount, and
         (B) (x) the documentation required to be delivered by a Holder to the
         Trustee pursuant to clause (c)(i) of this Section 2.06 or (y) a
         representation to the effect of clause (c)(ii) of this Section 2.06, as
         applicable, then the Registrar shall instruct the Depositary to reduce
         or cause to be reduced the principal amount of the Restricted Global
         Security and to increase or cause to be increased the principal amount
         of the Exchange Global Security by the aggregate principal amount of
         the interest in the Restricted Global Security to be exchanged or

         the Person specified in such instructions a beneficial interest in the
         Exchange Global Security having a principal amount equal to the
         principal amount by which the amount of the Restricted Global Security
         was reduced upon such exchange or transfer.

                  (vii)    REGULATION S GLOBAL SECURITY TO EXCHANGE GLOBAL
         SECURITY. Following the earlier of the consummation of the Exchange
         Offer or the transfer of a Security pursuant to a Shelf Registration
         Statement that results in beneficial interests in such Security being
         reflected in the Exchange Global Security, if the Holder of a
         beneficial interest in the Regulation S Global Security at any time
         wishes to exchange its interest in such Regulation S Global Security
         for an interest in the Exchange Global Security, or to transfer its
         interest in such Regulation S Global Security to a Person who wishes to
         take delivery thereof in the form of a beneficial interest in the
         Exchange Global Security, such transfer or exchange, if not effected
         pursuant to an Exchange Offer or a Shelf Registration Statement in
         accordance with Section 2.06(a), may be effected only in accordance
         with this clause (vii) and the Applicable Procedures. Upon receipt by
         the Registrar of instructions given in accordance with the Applicable
         Procedures directing the Registrar to credit or cause to be credited an
         interest in the Exchange Global Security in a specified principal
         amount and to cause to be debited an interest in the Regulation S
         Global Security in such specified principal amount, then the Registrar

         Security having a principal amount equal to the principal amount by
         which the amount of the Regulation S Global Security was reduced upon
         such exchange or transfer.

                  (viii)   GLOBAL SECURITIES TO CERTIFICATED SECURITIES. In the
         event that a Global Security is exchanged for Securities in
         certificated, registered form pursuant to

                                       30
<PAGE>

         Section 2.06(a), unless pursuant to an effective Shelf Registration
         Statement with respect to such Securities, such Securities may be
         exchanged only in accordance with such procedures as are substantially
         consistent with the provisions of clauses (iv) and (v) above (including
         the certification requirements intended to ensure that such transfers
         comply with Rule 144A or Regulation S under the Securities Act, as the
         case may be) and such other procedures as may from time to time be
         adopted by the Company or the Trustee.

                  (c)      Except in connection with an Exchange Offer or a
Shelf Registration Statement contemplated by and in accordance with the terms of
the Registration Rights Agreement, if Securities are issued upon the transfer,
exchange or replacement of Securities bearing the applicable Private Placement
Legend set forth in Exhibit C hereto, the Securities so issued shall continue to
bear the applicable Private Placement Legend, and a request to remove such
legend from Securities will not be honored unless (i) there is delivered to the
Trustee an opinion of counsel to the effect that neither such legend nor the
restrictions on transfer set forth therein are required to ensure that transfers
thereof comply with the provisions of the Securities Act or (ii) the date of
such transfer, exchange or replacement is two years after the later of (x) the
issue date of such Security and (y) the last date that the Company or any
affiliate (as defined in Rule 144 under the Securities Act) of the Company was
the owner of such Securities (or any predecessor Securities thereof). Upon
compliance with the foregoing, the Trustee, upon an Issue Order, shall
authenticate and deliver Securities that do not bear such legend.

                  (d)      The Trustee shall have no responsibility for any
actions taken or not taken by the Depositary, Euroclear or Clearstream, as the
case may be.

                  (e)      The Trustee shall have no obligation or duty to
monitor, determine or inquire as to compliance with any restrictions on transfer
imposed under this Indenture or under applicable law with respect to any
transfer of any interest in any Securities (including any transfers between or
among the Depositary's Participants or beneficial owners of interests in any
Global Security) other than to require delivery of such certificates and other
documentation, as is expressly required by, and to do so if and when expressly
required by, the terms of this Indenture and to examine the same to determine
substantial compliance as to form with the express requirements hereof.

                  Section 2.07. REPLACEMENT SECURITIES. If a mutilated Security
is surrendered to the Trustee or if the Holder of a Security claims that such
Security has been lost, destroyed or wrongfully taken, the Company shall issue a
replacement Security, and the Trustee shall authenticate such replacement
Security if the Trustee's requirements are met. If required by the Trustee or
the Company, an indemnity bond must be provided by the Securityholder that is
sufficient in the judgment of the Trustee and the Company to protect the
Company, the Trustee or any Agent from any loss which any of them may suffer if
a Security is replaced. The Company or the Trustee may charge such Holder for
its expenses in replacing a Security.

                  Every replacement Security is an additional obligation of the
Company.

                  Section 2.08. OUTSTANDING SECURITIES. Securities outstanding
at any time are all Securities that have been authenticated by the Trustee,
except for those canceled by it, those

                                       31
<PAGE>

delivered to it for cancellation and those described in this Section 2.08 as not
outstanding. A Security does not cease to be outstanding because the Company or
one of its Affiliates holds the Security.

                  If a Security is replaced pursuant to Section 2.07, it ceases
to be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a BONA FIDE purchaser.

                  If the Paying Agent holds (or, if the Company or a Subsidiary
is the Paying Agent, segregates and holds in trust), in accordance with this
Indenture, on the maturity or redemption date, money sufficient to pay
Securities payable on that date, then on and after that date such Securities
shall be deemed to be no longer outstanding and interest on them shall cease to
accrue.

                  Section 2.09. TREASURY SECURITIES. In determining whether the
Holders of the required principal amount of Securities have concurred in any
direction, waiver or consent, Securities owned by the Company or any of its
Affiliates shall be disregarded, except that for the purpose of determining
whether the Trustee shall be protected in relying on any such direction, waiver
or consent, only Securities which a Trust Officer of the Trustee actually knows
are so owned shall be so disregarded.

                  Section 2.10. TEMPORARY SECURITIES. Until definitive
Securities are ready for delivery, the Company may prepare, and the Trustee
shall authenticate upon written order of the Company signed by an Officer
thereof, temporary Securities. Temporary Securities shall be substantially in
the form of definitive Securities but may have variations that the Company
considers appropriate for temporary Securities. Without unreasonable delay, the
Company shall prepare, and the Trustee shall authenticate, definitive Securities
in exchange for temporary Securities.

                  Until such exchange, such temporary Securities shall be
entitled to the same rights, benefits and privileges as the definitive
Securities.

                  Section 2.11. CANCELLATION. The Company at any time may
deliver Securities to the Trustee for cancellation. The Registrar and the Paying
Agent shall forward to the Trustee any Securities surrendered to them for
registration of transfer, exchange or payment. The Trustee and no one else shall
cancel all Securities surrendered for registration of transfer, exchange,
payment or cancellation. The Company may not issue new Securities to replace
Securities it has paid or delivered to the Trustee for cancellation.

                  Section 2.12. DEFAULTED INTEREST. If the Company defaults in a
payment of interest on the Securities, it shall pay the defaulted interest,
plus, to the extent permitted by law, any interest payable on the defaulted
interest, to the Persons who are Securityholders on a subsequent special record
date. Such special record date shall be the fifteenth day next preceding the
date fixed by the Company for the payment of defaulted interest, whether or not
such day is a Business Day. At least 15 days before the special record date, the
Company shall mail or cause to be mailed to each Securityholder and the Trustee
a notice that states the special record date, the payment date and the amount of
defaulted interest to be paid.

                                       32
<PAGE>

                  Section 2.13. CUSIP AND ISIN NUMBERS. The Company in issuing
the Securities may use one or more "CUSIP" and "ISIN" numbers (if then generally
in use). If so, the Trustee shall use CUSIP and ISIN numbers, as appropriate, in
notices of redemption as a convenience to Securityholders; PROVIDED that any
such notice may state that no representation is made as to the correctness of
such numbers or codes either as printed on the Securities or as contained in any
notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers. The Company shall
promptly notify the Trustee of any change in a CUSIP or ISIN number.

                  Section 2.14. DEPOSIT OF MONEYS. On or before 11:00 A.M., New
York City time, on each payment date, the Company shall deposit with the Trustee
or Paying Agent in immediately available funds money sufficient to make cash
payments, if any, due on such payment date. The principal amount and interest
due on Book-Entry Securities shall be payable to the Depositary or its nominee,
as the case may be, as the sole registered owner and the sole holder of the
Book-Entry Securities represented thereby. The principal amount and interest on
Securities in certificated form shall be payable at the office of the Paying
Agent; PROVIDED HOWEVER that the Company, at its option, may pay interest by
check by mailing such check to the Holder's registered address.

                                  ARTICLE III
                                   REDEMPTION

                  Section 3.01. NOTICES TO TRUSTEE. If the Company elects to
redeem Securities pursuant to Section 3.02 below or paragraph 5(a) of the
Securities, it shall notify the Trustee in writing of the redemption date, the
principal amount of Securities to be redeemed and the provision of this
Indenture pursuant to which the redemption will occur.

                  The Company shall give the notice to the Trustee provided for
in this Section at least 45 days before the redemption date, unless the Trustee
consents in writing to a shorter notice period. Such notice shall be accompanied
by an Officers' Certificate and an Opinion of Counsel to the effect that such
redemption will comply with the conditions contained in this Indenture and will
set forth the redemption price.

                  Section 3.02. REDEMPTION PRICE. (a) Except as set forth in
paragraph (b) below and paragraph 5(a) of the Securities, the Securities will
not be redeemable at the option of the Company prior to August 1, 2009. Starting
on that date, the Company may redeem all or any portion of the Securities, at
once or over time, after giving the required notices specified in Sections 3.01
and 3.03. The Securities may be redeemed at the redemption prices set forth

forth below, and are expressed as percentages of principal amount:

Company and the Guarantors each covenants (to the full extent permitted by
applicable law) that it will not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, and will actively
resist any attempts to claim the benefit of any stay or extension law or any
usury law or other law which would prohibit or forgive the Company or any
Guarantor from paying all or any portion of the principal of or interest on the

hereafter in force, or which may affect the covenants or the performance of this

supplied with all necessary equipment and will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as in
the judgment of the Company or such Subsidiary may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; PROVIDED that nothing in this Section 4.08 shall prevent
the Company or any of its Subsidiaries from discontinuing the use, operation or
maintenance of any of such properties, or disposing of any of them, if such
discontinuance or disposal is not, in the judgment of the Board of Directors of
the Company or such Subsidiary, adverse in any material respect, to the Company
or the Holders.

         in the proviso to clause (1) above); PROVIDED that the liquidation
         value of any Preferred Stock issued pursuant to this clause (2) shall
         constitute Debt for purposes of this Section 4.09 and dividends on such
         Preferred Stock shall be included in determining Consolidated Interest
         Expense of the Company for purposes of calculating the Consolidated
         EBITDA Coverage Ratio of the Company under paragraph (a) of this
         Section 4.09; and

                           (3)      Preferred Stock (other than Redeemable
         Stock) of the Company.

                  (d)      To the extent the Company or any of its Subsidiaries
Guarantees any Debt of the Company or any other Subsidiary, such Guarantee and
such Debt will be deemed to be the same Debt and only the amount of the Debt
will be deemed to be outstanding. If the Company or any of its Subsidiaries
Guarantees any Debt of a Person that, subsequent to the Issuance of such
Guarantee, becomes a Subsidiary of the Company, such Guarantee and the Debt so
Guaranteed shall be deemed to be the same Debt, which shall be deemed to have
been Issued when the Guarantee was Issued and shall be deemed to be permitted to
the extent the Guarantee was permitted when Issued. Debt under Credit Facilities
outstanding on the Issue Date (including the Credit Agreement) shall be deemed
to have been made pursuant to clause (b)(8) of this Section 4.09.

                  Section 4.10. LIMITATION ON RESTRICTED PAYMENTS AND RESTRICTED
INVESTMENTS. (a) So long as no Default or an Event of Default shall have
occurred and be continuing, the Company may make, and may permit any of its
Subsidiaries to make, directly or indirectly, any Restricted Payment or
Restricted Investment so long as, at the time of such Restricted Payment or
Restricted Investment and immediately after giving effect thereto, the aggregate
amount of Restricted Payments made since the Issue Date and the aggregate amount
of Restricted Investments made since the Issue Date and then outstanding (the
amount expended for such purposes, if other than in cash, shall be the fair
market value of such property as determined by the Board of Directors of the
Company in good faith as of the date of payment or investment) shall not exceed
the sum of:

                  (i)      50% of the cumulative Consolidated Net Income (or
         minus 100% of the cumulative Consolidated Net Loss) of the Company
         accrued during the period beginning January 1, 2001 and ending on the
         last day of the most recently completed fiscal quarter for which
         financial information has been provided to the Holders in accordance
         with Section 4.06 but ending no more than 135 days prior to the date of
         such Restricted Payment or Restricted Investment (treating such period
         as a single accounting period);

                  (ii)     100% of the net cash proceeds, including the fair
         market value of property other than cash as determined by the Board of
         Directors of the Company in good faith, as evidenced by a Board
         Resolution, received by the Company from any Person (other than a
         Subsidiary of the Company) from the Issuance and sale subsequent to the

                                       41
<PAGE>

         Issue Date of Capital Stock of the Company (other than Redeemable
         Stock) or as a capital contribution; PROVIDED that, if the value of the
         non-cash consideration or contribution is in excess of $10,000,000, the
         Company shall have received the written opinion of a nationally
         recognized investment banking firm that the terms thereof, from a
         financial point of view, are fair to the shareholders of the Company or
         such Subsidiary, in their capacity as such (the determination as to the
         value of any non-cash consideration referred to in this clause (ii) to
         be made by such investment banking firm), and such opinion shall have
         been delivered to the Trustee;

                  (iii)    100% of the net cash proceeds received by the Company
         from the exercise of options or warrants on Capital Stock of the
         Company (other than Redeemable Stock) since the Issue Date;

                  (iv)     100% of the net cash proceeds received by the Company
         from the conversion into Capital Stock (other than Redeemable Stock) of
         convertible Debt or convertible Preferred Stock issued and sold (other
         than to a Subsidiary of the Company) since the Issue Date; and

                  (v)      $60,000,000.

                  The designation by the Company or any of its Subsidiaries of a
Subsidiary as a Non-Recourse Subsidiary shall be deemed to be the making of a
Restricted Investment by the Company in an amount equal to the outstanding
Investments made by the Company and its Subsidiaries in such Person being
designated a Non-Recourse Subsidiary at the time of such designation.

                  (b)      Section 4.10(a) shall not prevent the following, as
long as no Default or Event of Default shall have occurred and be continuing (or
would result therefrom other than pursuant to Section 4.10(a):

                  (1)      the making of any Restricted Payment or Restricted
         Investment within 60 days after (x) the date of declaration thereof or
         (y) the making of a binding commitment in respect thereof; PROVIDED
         that at such date of declaration or commitment such Restricted Payment
         or Restricted Investment complied with Section 4.10(a);

                  (2)      any Restricted Payment or Restricted Investment made
         out of the net cash proceeds received by the Company from the
         substantially concurrent sale of its Common Stock (other than to a
         Subsidiary of the Company); PROVIDED that such net cash proceeds so
         utilized shall not be included in paragraph (a) in determining the
         amount of Restricted Payments or Restricted Investments the Company
         could make under Section 4.10(a);

                  (3)      cumulative Investments in Non-Recourse Subsidiaries
         not in excess of $50,000,000 in the aggregate from the Issue Date
         determined as of the date of the Investment (the amount so expended, if
         other than cash, to be determined by the Company's Board of Directors,
         as evidenced by a Board Resolution); and

                                       42

         case from employees, former employees or directors of the Company or
         any of its Subsidiaries (other than any Permitted Holder); PROVIDED,
         HOWEVER, that the aggregate amount of Restricted Payments made under
         this clause (4) shall not exceed $1,500,000 in any fiscal year;
         PROVIDED, FURTHER, that if any portion of the aggregate amount of
         Restricted Payments permitted to be made pursuant to this clause (4)
         shall not be made in a fiscal year, Restricted Payments pursuant to
         this clause (4) in amount not to exceed to such unused portion may be
         made in the subsequent fiscal year in addition to all other Restricted
         Payments permitted to be made pursuant to this clause (4) in that
         fiscal year.

Restricted Payments or Restricted Investments made pursuant to clause (2), (3)
or (4) of this paragraph (b) shall not be deducted in determining the amount of
Restricted Payments or Restricted Investments made or then outstanding under
paragraph (a) of this Section 4.10.

                  Section 4.11. LIMITATION ON LIENS. (a) The Company shall not,
and shall not permit any of its Subsidiaries to, directly or indirectly, incur
or suffer to exist any Liens upon their respective property or assets whether
owned on the Issue Date or acquired after such date, or on any income or profits
therefrom, unless the Securities are equally and ratably secured by such Lien;
PROVIDED that if the Debt secured by such Lien is subordinate or junior in right
of payment to the Securities then the Lien securing such Debt shall be
subordinate or junior in priority to the Lien securing the Securities at least
to the same extent as such Debt is subordinate or junior to the Securities.

                  (b)      The foregoing restrictions of paragraph (a) of this
Section 4.11 shall not apply to:

                  (1)      Liens existing on the Issue Date;

                  (2)      Permitted Liens;

         additions to such assets, or replacements thereof; PROVIDED that (i)
         such acquisition, improvement or addition is otherwise permitted by
         this Indenture, (ii) the principal amount of Debt (including Debt in
         respect of Capitalized Lease Obligations) secured by each such Lien on
         each asset shall not exceed the cost (including all such Debt secured
         thereby, whether or not assumed) of the item subject thereto, and such
         Liens shall attach solely to the particular item of property so
         acquired, improved or added and any additions or accessions thereto, or
         replacements thereof, and (iii) the aggregate amount of Debt secured by
         Liens permitted by this clause (3) shall not at any time exceed
         $100,000,000;

                  (4)      Liens on the Company's existing facility in
         Baltimore, Maryland securing Debt in an aggregate amount at any one
         time outstanding not to exceed $40,000,000;

                  (5)      Liens to secure Refinancing of any Debt secured by
         Liens described in clauses (1)-(4) and (6) of this paragraph (b);
         PROVIDED that (i) such Refinancing does not increase the principal
         amount of Debt being so Refinanced and (ii) the Lien of the

                                       43
<PAGE>

         Refinancing Debt does not extend to any asset not securing the Debt
         being Refinanced or improvements or additions thereto, or replacements
         thereof;

                  (6)      Liens securing Acquired Debt; PROVIDED that (i) any
         such Lien secured the Acquired Debt at the time of the incurrence of
         such Acquired Debt by the Company or by one of its Subsidiaries and
         such Lien and Acquired Debt were not incurred by the Company or any of
         its Subsidiaries or by the Person being acquired or from whom the
         assets were acquired in connection with, or in anticipation of, the
         incurrence of such Acquired Debt by the Company or by one of its
         Subsidiaries and (ii) any such Lien does not extend to or cover any
         property or assets of the Company or of any of its Subsidiaries other
         than the property or assets that secured the Acquired Debt prior to the
         time such Debt became Acquired Debt of the Company or of one of its
         Subsidiaries;

         paragraph (b)(2) of Section 4.09;

                  (9)      Liens on assets of the Company and its Subsidiaries
         in addition to those referred to in clauses (1)-(8) of this paragraph
         (b); PROVIDED that such Liens only secure Debt of the Company and its
         Subsidiaries in an aggregate amount not to exceed at any one time
         outstanding the greater of (i) $85,000,000 and (ii) 10% of Consolidated
         Tangible Assets.

or those transactions specifically permitted by Section 4.10(b), (y)
transactions between or among Non-Recourse Subsidiaries of the Company or (z)
transactions between or among the Company and its Subsidiaries (other than

of any service, unless the terms of such transaction or series of transactions
are set forth in writing and are at least as favorable as those available in a
comparable transaction in arms-length dealings from an unrelated Person;
PROVIDED that: (i) if any such transaction or series of related transactions
(other than any purchase or sale of inventory in the ordinary course of
business, but including entering into any long-term arrangement involving the
purchase of granules or glass fiber from, or the provision of management
services of the type currently provided under the Management Agreement by, an
Affiliate of the Company, including ISP or a Subsidiary thereof) involves
aggregate payments or other consideration in excess of $25,000,000, such
transaction or series of related transactions shall be approved (and the value
of any non-cash consideration shall be determined) by a majority of those
members of the Board of Directors of the Company or such Subsidiary, as the case
may be, having no personal stake in such business, transaction or transactions;
and (ii) in the event that such transaction or series of related transactions
(other than any purchase or sale of inventory in the ordinary course of business

(with the value of any non-cash consideration being determined by a majority of
those members of the Board of Directors of the Company or such Subsidiary, as
the case may be, having no personal stake in such business, transaction or
transactions), the Company or such Subsidiary, as the case may be, shall have
also received a written opinion from a nationally recognized investment banking
firm that such transaction or series of related transactions is fair to the
shareholders, in their capacity as such, of the Company or such Subsidiary from
a financial point of view and such opinion has been delivered to the Trustee;
PROVIDED FURTHER, in the event that each member of the Board of Directors of the
Company or the Subsidiary, as the case may be, proposing to engage in a
transaction or series of related transactions described in the preceding proviso
has a personal stake in such business, transaction or transactions, the Company
or such Subsidiary may enter into such transaction or series of transactions if
the Company or such Subsidiary, as the case may be, shall have received the
written opinion of a nationally recognized investment banking firm that the
terms thereof, from a financial point of view, are fair to the shareholders of
the Company or such Subsidiary, in their capacity as such (the determination as
to the value of any non-cash consideration referred to in the preceding proviso
to be made by such investment banking firm), and such opinion shall have been
delivered to the Trustee.

                  (b)      Paragraph (a) of this Section 4.12 shall not prevent
the following:

         of the Company, including ISP or a Subsidiary of ISP; PROVIDED that (i)
         subject to Section 4.12(c), the price and other terms shall not be less

         or (ii) a nationally recognized investment banking firm or accounting
         firm has delivered a written opinion to the Company to the effect that
         either the terms thereof are fair to the Company from a financial point
         of view or are on terms at least as favorable to the Company as those
         available in comparable transactions in arms-length dealings from an
         unrelated Person;

                           (2)      the continuance of the Management Agreement
         (including with an Affiliate of the Company other than ISP) (i) in
         accordance with its terms or on terms no less favorable to the Company
         than those contained in the Management Agreement or (ii) on other terms
         PROVIDED that the Company shall have received the written opinion of a
         nationally recognized investment banking firm or accounting firm that
         either the terms thereof, from a financial point of view, are fair to
         the Company or are on terms at least as favorable to the Company as
         those available in comparable transactions in arms-length dealings from
         an unrelated Person;

                           (3)      any transaction between the Company or a
         Subsidiary thereof and its own employee stock ownership or benefit
         plan;

                           (4)      any transaction with an officer or director
         of the Company or any Subsidiary of the Company entered into in the
         ordinary course of business (including compensation or employee benefit
         arrangements with any such officer or director);

                           (6)      borrowings by the Company or its
         Subsidiaries from Affiliates of the Company; PROVIDED that such loans
         are unsecured, are prepayable at any time without penalty, contain no
         restrictive covenants and the effective cost of borrowings thereunder
         do not exceed the interest rate then in effect from time to time under
         the Credit Agreement or any Refinancings thereof (or, if such agreement
         is not outstanding, under the unsecured bank debt of the Company); or

                           (7)      payments made pursuant to the Tax Sharing
         Agreement.

its Subsidiaries to, amend, modify or waive any provision of the Tax Sharing
Agreement or the Granules Contract in any manner which is significantly adverse
to the Company or the Holders (it being understood that an extension or
modification of any of the Granules Contract (or any similar granules purchase
contract) on terms at least as favorable to the Company as those available at
the time of the extension or modification (or any such new agreement) in a
comparable transaction in arms-length dealings with an unrelated Person shall
not be deemed significantly adverse to the Company or the Holders).

dividends or make any other distributions on its Capital Stock or pay any Debt
owed to the Company or any of its Subsidiaries, (b) make loans or advances to
the Company or any of its Subsidiaries, (c) transfer any of its properties or
assets to the Company or (d) incur or suffer to exist Liens in favor of the

                           (4)      any instrument governing Acquired Debt of
         any Person, which encumbrance or restriction is not applicable to any
         Person, or the properties or assets of any Person, other than such
         Person and its Subsidiaries, or the property or assets of such Person
         and its Subsidiaries, so acquired;

                           (5)      the Liens specifically permitted by Section
         4.11; PROVIDED that such Liens and the terms governing such Liens do
         not, directly or indirectly, restrict the Company or its Subsidiaries
         from granting other Liens, except as to the assets subject to such
         Liens;

                           (6)      the Credit Agreement or other Debt existing
         on the Issue Date; and

                           (7)      any Refinancing of the Credit Agreement or
         any such other Debt existing on the Issue Date; PROVIDED that the terms
         and conditions of any such Refinancing agreements relating to the terms
         described in paragraphs (a)-(d) above are no less favorable to the
         Company than those contained in the agreements governing the Debt being
         Refinanced.

                  Section 4.14. CHANGE OF CONTROL. (a) In the event of any
Change of Control, each Holder shall have the right, at such Holder's option, to
require the Company to repurchase all or any part (equal to $1,000 or an
integral multiple thereof) of that Holder's Securities pursuant to a Change of
Control offer on the date (the "CHANGE OF CONTROL PAYMENT DATE") which is 25
Business Days after the date the Change of Control Notice (as defined below) is
mailed or required to be mailed (or such later date as is required by applicable
law) at 101% of the principal amount thereof, plus accrued interest to the
Change of Control Payment Date (the "PUT AMOUNT").

                  (b)      The Company or, at the request of the Company, the
Trustee shall send, by first-class mail, postage prepaid, to all Holders, within
ten Business Days after the occurrence of each Change of Control, a notice of
the occurrence of such Change of Control (the "CHANGE OF CONTROL NOTICE"),
specifying a date by which a Holder must notify the Company of such Holder's
intention to exercise the repurchase right and describing the procedure that
such Holder must follow to exercise such right. The Company is required to
deliver a copy of such notice to the Trustee and to cause a copy of such notice
to be published in a daily newspaper of national circulation.

                  Each Change of Control Notice shall state:

                           (1)      that a Change of Control has occurred, that
         each Holder has the right to require the Company to repurchase all or
         any part of such Holder's Security at a purchase price in cash equal to
         their Put Amount, that the Change of Control offer is being made
         pursuant to this Section 4.14 and that all Securities tendered will be
         accepted for payment;

                           (2)      the purchase price and the Change of Control
         Payment Date;

                           (3)      that any Security not tendered will continue
         to accrue interest;

                           (4)      that, unless the Company defaults in making
         payment therefor, any Security accepted for payment pursuant to the
         change of control offer shall cease to accrue interest after the Change
         of Control Payment Date;

                           (5)      that Holders electing to have a Security
         purchased pursuant to a Change of Control offer will be required to
         surrender the Security, with the form entitled "Option of Holder to
         Elect Purchase" on the reverse of the Security completed, to the Paying
         Agent at the address specified in the notice prior to the close of
         business on the Business Day prior to the Change of Control Payment
         Date;

                           (6)      that Holders will be entitled to withdraw
         their election if the Paying Agent receives, not later than five
         Business Days prior to the Change of Control

                           Company may defer making a Net Proceeds Offer until
                           the aggregate Net Cash Proceeds from Asset Sales to
                           be applied pursuant to this clause (3)(iii) equal or

         pursuant to this Section 4.15 and that all Securities tendered will be
         accepted for payment; PROVIDED that, if the aggregate principal amount
         of Securities tendered in a Net Proceeds Offer exceeds the aggregate
         amount available for the Net Proceeds Offer, the Company shall select
         the Securities to be purchased on a pro rata basis (with such
         adjustments as may be deemed appropriate by the Company, so that only
         Securities in denominations of $1,000 or multiples thereof shall be
         purchased);

                           (2)      the purchase price and the purchase date

                           (4)      that, unless there is a default in making
         payment therefor, any Security accepted for payment pursuant to the Net
         Proceeds Offer shall cease to accrue interest after the Proceeds
         Purchase Date;

                           (5)      that Holders electing to have a Security

         Elect Purchase" on the reverse of the Security completed, to the Paying
         Agent at the address specified in the notice prior to the close of
         business on the Business Day prior to the Proceeds Purchase Date;

                           (6)      that Holders will be entitled to withdraw
         their election if the Paying Agent receives, not later than two
         Business Days prior to the Proceeds Purchase Date, a facsimile
         transmission or letter setting forth the name of the Holder, the
         principal amount of the Securities the Holder delivered for purchase

SUBSIDIARIES. If the Company transfers or causes to be transferred, in one or a
series of related transactions, Material Assets to any one or more Non-Recourse
Subsidiaries of the Company, the Company shall cause each such transferee
Subsidiary to (i) execute and deliver to the Trustee a supplemental indenture in
form reasonably satisfactory to the Trustee pursuant to which such transferee
Subsidiary shall unconditionally Guarantee, on a senior basis, all the Company's
obligations under the Securities and (ii) deliver to the Trustee an Opinion of
Counsel that such supplemental indenture has been duly executed and delivered by
such transferee Subsidiary.

                  Section 4.17. INVESTMENT COMPANY ACT. The Company will not
take any action that would require it or any of its Subsidiaries to register as
an investment company under the Investment Company Act of 1940.

                  Section 4.18. GUARANTEES BY SUBSIDIARIES. The Company shall
not permit any Recourse Subsidiary that is not a Guarantor, directly or
indirectly, to Issue any Debt or Preferred Stock or to Guarantee or secure the
payment of any other Debt of the Company or any of its Recourse Subsidiaries,
unless such Subsidiary simultaneously executes and delivers a supplemental
indenture to this Indenture providing for a Subsidiary Guarantee of the payment
of the Securities by such Subsidiary; PROVIDED that this Section 4.18 not be
applicable to: (i) Acquired Debt; (ii) any Guarantee of any Subsidiary that
existed at the time such Person became a Subsidiary and was not incurred in
connection with, or in contemplation of, such Person becoming a Subsidiary;
(iii) any Guarantee arising under or in connection with performance bonds,
indemnity bonds, surety bonds or letters of credit or bankers' acceptances; or
(iv) Permitted Liens. If the Guaranteed Debt is a Subordinated Obligation, the
Guarantee of such Guaranteed Debt must be subordinated in right of payment to
the Subsidiary Guarantee to at least the extent that the Guaranteed Debt is
subordinated to the Securities or the applicable Subsidiary Guarantee.

                  Section 4.19. CONSENTS, ETC. The Company shall not, and shall
not permit any of its Subsidiaries to, directly or indirectly, pay or cause to
be paid any consideration, whether by way of interest, fee or otherwise, to any
Holder for or as an inducement to any consent, waiver or amendment of any terms
or provisions of the Securities unless such consideration is offered to be paid
or agreed to be paid to all Holders which so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or amendment

                  Section 4.20. SUSPENSION OF CERTAIN COVENANTS. During any
period of time that (a) the Securities have Investment Grade Ratings from both
Rating Agencies and (b) no Default or Event of Default has occurred and is
continuing under this Indenture, the Company and its Recourse Subsidiaries will
not be subject to the covenants of this Indenture described under Sections 4.09,
4.10, 4.12, 4.13, 4.15, 4.16 and 4.18 and clauses (3) and (4) of paragraph (a)
of Section 5.01 hereof (collectively, the "SUSPENDED COVENANTS"). If the Company
and its Recourse Subsidiaries are not subject to the Suspended Covenants for any
period of time as a result of the previous sentence and, subsequently, one, or
both, of the Rating Agencies withdraws its ratings or downgrades the ratings
assigned to the Securities below the required Investment Grade Ratings or a
Default or Event of Default occurs and is continuing, then the Company and its
Recourse Subsidiaries will thereafter again be subject to the Suspended
Covenants. The

                                       51
<PAGE>

ability of the Company and its Recourse Subsidiaries to make future Restricted
Payments after the time of such withdrawal, downgrade, Default or Event of
Default will be calculated as if the covenant contained within Section 4.10 had
been in effect during the entire period of time from the Issue Date.

                    (6)    principal of or interest on Debt of the Company or
         any of its Significant Subsidiaries is not paid within any applicable
         grace period or is accelerated by the holders thereof because of a
         default and the total amount that is unpaid or accelerated exceeds
         $25,000,000 or its foreign currency equivalent and such default
         continues for 5 days after notice;

                    (7)    the Company or any of its Significant Subsidiaries

         days following the entry of such judgment or order during which such
         judgment or order is not discharged, waived or the execution thereof

         specified below or (ii) foreclosure proceedings therefor have begun and
         have not been stayed within five days of the commencement of such
         foreclosure proceeding.

                  A Default under clauses (4), (5), (6) or (8) is not an Event

Holders of at least 25% in aggregate principal amount of the outstanding
Securities, by written notice to the Company and the Trustee, may declare all
unpaid principal of and accrued interest on the Securities then outstanding to
be due and payable (the "DEFAULT Amount"). Upon a declaration of acceleration,
such amount shall be due and payable immediately.

                  If an Event of Default with respect to the Company specified
in Section 6.01(7) occurs, the Default Amount shall IPSO FACTO become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder.

                  The Holders of a majority in aggregate principal amount of the
Securities then outstanding, by written notice to the Trustee and the Company,
may rescind an acceleration with respect to the Securities and its consequences
if (i) all existing Defaults and Events of Default, other than the non-payment
of the principal of the Securities which has become due solely by such
declaration of acceleration, have been cured or waived, (ii) to the extent the
payment of such interest is lawful, interest on overdue principal, which has
become due otherwise than by such declaration of acceleration, has been paid and
(iii) the rescission would not conflict with any judgment or decree of a court
of competent jurisdiction.

                  Section 6.03. OTHER REMEDIES. Notwithstanding any other
provision of this Indenture, if an Event of Default occurs and is continuing and
the Holders are entitled to payment as a result of acceleration, the Trustee may
pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of and/or interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.

                                       54

                  The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Securityholder in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

                  Section 6.04. WAIVER OF PAST DEFAULTS. Subject only to the
provisions of Sections 6.07 and 9.02, the Holders of a majority in aggregate
principal amount of the outstanding Securities by notice to the Trustee may
waive an existing Default or Event of Default and its consequences, except a
Default or Event of Default in payment of principal or interest on any Security
as specified in clauses (1) and (2) of Section 6.01. When a Default or Event of
Default is waived, it is cured and ceases to exist.

                  Section 6.05. CONTROL BY MAJORITY. The Holders of a majority
in aggregate principal amount of the outstanding Securities may direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or of exercising any trust or power conferred on the Trustee. The
Trustee, however, may refuse to follow any direction that conflicts with law or
this Indenture or that the Trustee determines is unduly prejudicial to the
rights of any other Holder or that would involve the Trustee in personal
liability. The Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction.

                  Section 6.06. LIMITATION ON REMEDIES. Except as provided in
Section 6.07, a Holder may not pursue any remedy with respect to this Indenture
or the Securities unless:

                    (1)    such Holder has previously given the Trustee written
         notice that an Event of Default is continuing,

                    (2)    Holders of at least 25% in aggregate principal amount
         of the outstanding Securities have made a written request to the
         Trustee to pursue the remedy,

                    (3)    such Holders have offered the Trustee reasonable
         security or indemnity against any loss, liability or expense,

                    (4)    the Trustee has not complied with such request within
         60 days after the receipt of the request and the offer of security or
         indemnity; and

                    (5)    the Holders of a majority in aggregate principal
                           amount of the outstanding Securities have not given
         the Trustee a direction inconsistent with such request within such
         60-day period.

                  A Securityholder may not use this Indenture to prejudice the
rights of another Securityholder or to obtain a preference or priority over such
other Securityholder.

                  Section 6.07. RIGHTS OF HOLDERS TO RECEIVE PAYMENT.
Notwithstanding any other provision of this Indenture, the right of any Holder
of a Security to receive payment of the principal amount of and interest on the
Security, on or after the respective due dates expressed in

                                       55
<PAGE>

the Security, or to bring suit for the enforcement of any such payment on or
after such respective dates, shall not be impaired or affected without the
consent of such Holder.

                  Section 6.08. COLLECTION SUIT BY TRUSTEE. If an Event of
Default specified in clause (1) or (2) of Section 6.01 occurs and is continuing,
the Trustee may recover judgment in its own name and as trustee of an express
trust against the Company or any other obligor on the Securities for the whole
amount of the principal amount, together with, to the extent that payment of
such interest is lawful, interest on overdue principal, at the rate PER ANNUM
specified in the Securities, and such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

                  Section 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee
may file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and the Securityholders allowed in any judicial
proceedings relative to the Company (or any other obligor upon the Securities),
its creditors or its property. The Trustee shall be entitled and empowered to
participate as a member, voting or otherwise, of any offical committee of
creditors appointed in such matter and to collect, receive and distribute any
money or other property payable or deliverable on any such claims and any
custodian in any such judicial proceedings is hereby authorized by each
Securityholder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the
Securityholders, to pay to the Trustee any amount due to the Trustee for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section
7.07. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Securityholder any
plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Securityholder in any such proceeding.

                  Section 6.10. PRIORITIES. If the Trustee collects any money
pursuant to this Article VI, it shall pay out the money in the following order:

                  First:  to the Trustee for amounts due under Section 7.07;

                  Second: to Securityholders for amounts due and unpaid on the
Securities ratably, without preference or priority of any kind, according to the
amounts due and payable on the Securities for the principal amount and interest,
respectively; and

                  Third:  to the Company.

                  The Trustee may fix a record date and payment date for any
payment to Securityholders pursuant to this Section 6.10.

                  Section 6.11. UNDERTAKING FOR COSTS. In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the

                                       56
<PAGE>

suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in the suit, having due regard to the
merits and good faith of the claims or defenses made by the party litigant. This
Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.07, or a suit by any Holder or a group of Holders of more
than 10% in principal amount of the outstanding Securities.

                  Section 6.12. RESTORATION OF RIGHTS AND REMEDIES. If the
Trustee or any Holder has instituted any proceeding to enforce any right or
remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to the Trustee or to
such Holder, then, and in every such case, subject to any determination in such
proceeding, the Company, the Trustee and the Holders shall be restored severally
and respectively to their former positions hereunder and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

                  Section 6.13. NOTIFICATION TO COLLATERAL AGENT. If an Event of
Default occurs and is continuing, the Trustee shall notify the Collateral Agent
(as defined in the Collateral Agent Agreement) of such default pursuant to the
terms of the Collateral Agent Agreement and take any action as may be required
thereby.

                                   ARTICLE VII

                                     TRUSTEE

                  Section 7.01. RIGHTS OF TRUSTEE. (A) GENERAL. The duties and
responsibilities of the Trustee shall be as provided by the TIA and as set forth
herein. Notwithstanding the foregoing, no provision of this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder, or in the
exercise of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. Whether or not herein expressly so
provided, every provision of this Indenture relating to the conduct or affecting
the liability of or affording protection to the Trustee shall be subject to the
provisions of this Article VII.

                  (B) CERTAIN RIGHTS OF TRUSTEE. Subject to TIA Sections 315(a)
through (d):

                  (i) the Trustee may conclusively rely, and shall be protected
         in acting or refraining from acting, upon any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document believed by it to be genuine and to have
         been signed or presented by the proper Person;

                  (ii) before the Trustee acts or refrains from acting, it may
         require an Officers' Certificate or an Opinion of Counsel, which shall
         conform to SECTION 12.05. The Trustee shall not be liable for any
         action it takes or omits to take in good faith in reliance on such
         Officers' Certificate or Opinion of Counsel;

                                       57
<PAGE>

                  (iii) the Trustee may act through its attorneys and agents and
         shall not be responsible for the misconduct or negligence of any
         attorney or agent appointed with due care by it hereunder;

                  (iv) the Trustee shall be under no obligation to exercise any
         of the rights or powers vested in it by this Indenture at the request
         or direction of any of the Holders of Securities unless such Holders
         shall have offered to the Trustee security or indemnity reasonably
         satisfactory to it against the costs, expenses and liabilities that
         might be incurred by it in compliance with such request or direction;

                  (v) the Trustee shall not be liable for any action it takes or
         omits to take in good faith that it believes to be authorized or within
         its rights or powers, PROVIDED that the Trustee's conduct does not
         constitute negligence or bad faith;

                  (vi) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled to examine the
         books, records and premises of the Company personally or by agent or
         attorney;

                  (vii) the Trustee may consult with counsel of its selection
         and the advice of such counsel or any Opinion of Counsel shall be full
         and complete authorization and protection in respect to any action
         taken, suffered or omitted by it hereunder in good faith and in
         reliance thereon;

                  (viii) the Trustee shall not be deemed to have notice of any
         Default or Event of Default unless a Trust Officer of the Trustee has
         actual knowledge thereof or unless written notice of any event which is
         in fact such a default is received by the Trustee at the Corporate
         Trust Office of the Trustee, and such notice references the Securities
         and this Indenture;

                  (ix) the rights, privileges, protections, immunities and
         benefits given to the Trustee, including, without limitation, its right
         to be indemnified, are extended to, and shall be enforceable by, the
         Trustee in each of its capacities hereunder, and to each agent,
         custodian and other Person employed to act hereunder;

                  (x) the Trustee may request that the Company deliver an
         Officers' Certificate setting forth the names of individuals and/or
         titles of officers authorized at such time to take specified actions
         pursuant to this Indenture, which Officers' Certificate may be signed
         by any person authorized to sign an Officers' Certificate, including
         any person specified as so authorized in any such certificate
         previously delivered and not superseded; and

                  (xi) in the event that the Company is required to pay Special
         Interest, the Company will provide written notice to the Trustee of its
         obligation to pay the Special

                                       58
<PAGE>

         Interest no later than the Record Date for the next Interest Payment
         Date, which notice shall set forth the amount of the Special Interest
         to be paid by the Company on such Interest Payment Date. The Trustee
         shall not at any time be under any duty or responsibility to any Holder
         to determine the increased interest rate, or with respect to the
         nature, extent or calculation of the amount of such Special Interest,
         or with respect to the method employed in its calculation.

                  Section 7.02. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or any of its Affiliates with the same
rights it would have if it were not Trustee. Any Agent or Affiliate (including
without limitation the Initial Purchasers) may do the same with like rights.
However, the Trustee is subject to TIA ss.ss. 310(b) and 311.

                  Section 7.03. MONEY HELD IN TRUST. The Trustee shall not be
liable for interest on any money received by it except as the Trustee may agree
in writing with the Company. Money held in trust by the Trustee need not be
segregated from other funds except to the extent required by law.

                  Section 7.04. TRUSTEE'S DISCLAIMER. The Trustee makes no
representation as to the legality or validity or adequacy of this Indenture or
the Securities, it shall not be accountable for the Company's use of the
proceeds from the Securities, it shall not be responsible for the use or
application of any money received by any Paying Agent other than the Trustee and
it shall not be responsible for any statement in the Securities other than its
certificate of authentication.

                  Section 7.05. NOTICE OF DEFAULTS. If a Default occurs and is
continuing and is known to the Trustee, the Trustee shall mail to each Holder
notice of the Default within 90 days after it occurs. Except in the case of a
Default in the payment of the principal of or interest on any Security, the
Trustee may withhold notice if and so long as a committee of its Trust Officers
in good faith determines that withholding notice is in the interests of the
Holders.

                  Section 7.06. REPORTS BY TRUSTEE TO HOLDERS. Within 60 days
after each May 15 beginning with the May 15 following the Issue Date, the
Trustee shall mail to each Securityholder a report dated as of May 15 as to the
matters set forth in TIA ss. 313(a) if required by TIA ss. 313(a). The Trustee
also shall comply with TIA ss.ss. 313(b) and 313(c).

                  A copy of each such report at the time of its mailing to
Securityholders shall be filed with the Commission and each stock exchange, if
any, on which the Securities are listed.

                  The Company shall promptly notify the Trustee in writing if
the Securities become listed on any national securities exchange or of any
delisting thereof.

                  Section 7.07. COMPENSATION AND INDEMNITY. The Company and the
Guarantors, jointly and severally, agree that they shall pay to the Trustee from
time to time such compensation as the Company and the Trustee shall agree in
writing for its services. The Trustee's compensation shall not be limited by any
law on compensation relating to the trustee of an express trust. The Company and
the Guarantors, jointly and severally, agree that they shall reimburse the
Trustee upon request for all reasonable disbursements, expenses and advances

                                       59
<PAGE>

incurred or made by it. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel. Such expenses
shall also include any taxes or other reasonable costs incurred by the trust
created under Section 8.01.

                  The Company and the Guarantors, jointly and severally, shall
indemnify each of the Trustee and any predecessor Trustee for, and hold it
harmless against, any and all loss, damage, claim or liability or expense,
including taxes (other than taxes based on the income of the Trustee) arising of
or incurred by it in connection with the acceptance or administration of this
trust and its duties hereunder, including the costs and expenses of enforcing
this Indenture against the Company or the Guarantors (including this Section
7.07) of defending itself against any claim (whether asserted by any Holder, the
Company or any Guarantor) or liability in connection with the acceptance,
exercise or performance of any of its powers or duties hereunder. The Trustee
shall notify the Company promptly of any claim asserted against the Trustee for
which it may seek indemnity. Failure by the Trustee to so notify the Company
shall not relieve the Company of its obligations hereunder unless the Company is
actually prejudiced thereby. The Company shall defend the claim and the Trustee
shall cooperate in the defense. The Trustee may have separate counsel and the
Company shall pay the reasonable fees and expenses of such counsel. The Company
need not reimburse the Trustee for any expense or indemnify the Trustee against
any loss or liability incurred by the Trustee through negligence or bad faith.

                  To secure the Company's and the Guarantors' payment
obligations in this Section 7.07, the Trustee shall have a Lien prior to the
Securities on all money or property held or collected by the Trustee except
money or property held in trust to pay principal or interest on particular
Securities.

                  When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 6.01(7), the expenses
and the compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

                  The Company's and the Guarantors' obligations under this
Section 7.07 and any Lien arising hereunder shall survive the resignation or
removal of any Trustee, the discharge of the Company's obligations pursuant to
Article VIII and/or the termination of this Indenture.

                  Section 7.08. REPLACEMENT OF TRUSTEE. A resignation or removal
of the Trustee and the appointment of a successor Trustee shall become effective
only upon the successor Trustee's acceptance of appointment as provided in this
Section 7.08. The Trustee may resign by so notifying the Company in writing at
least 30 days prior to the date of the proposed resignation. The Holders of a
majority in aggregate principal amount of the outstanding Securities may remove
the Trustee by so notifying a Trust Officer of the Trustee in writing and may
appoint a successor Trustee with the Company's consent. The Company may remove
the Trustee if:

                    (1)    the Trustee fails to comply with Section 7.10;

                    (2)    the Trustee is adjudged a bankrupt or an insolvent or
         an order for relief is entered with respect to the Trustee under any
         Bankruptcy Law;

                                       60
<PAGE>

                    (3)    a receiver or other public officer takes charge of
         the Trustee or its property; or (4) the Trustee becomes incapable of
         acting.

                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. The Trustee shall be entitled to payment of its fees and
reimbursement of its expenses while acting as Trustee, and to the extent such
amounts remain unpaid, the Trustee that has resigned or has been removed shall
retain the Lien afforded by Section 7.07. Within one year after the successor
Trustee takes office, the Holders of a majority in aggregate principal amount at
maturity of the outstanding Securities may appoint a successor Trustee to
replace the successor Trustee appointed by the Company.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately thereafter,
subject to the Lien provided in Section 7.07, the retiring Trustee shall
transfer all property held by it as Trustee to the successor Trustee, the
resignation or removal of the retiring Trustee shall become effective and the
successor Trustee shall have all the rights, powers and duties of the retiring
Trustee under this Indenture. A successor Trustee shall mail notice of its
succession to each Securityholder.

                  If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of at least 10% in aggregate principal amount of the
outstanding Securities may petition, at the expense of the Company, any court of
competent jurisdiction for the appointment of a successor Trustee.

                  If any Trustee fails to comply with Section 7.10, any
Securityholder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee. Any successor Trustee
shall comply with TIA ss. 310(a)(5).

                  Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company's and the Guarantors' obligations under Section 7.07
shall continue for the benefit of the retiring Trustee.

                  Section 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business to, another corporation or national banking
association, the resulting, surviving or transferee corporation or national
banking association without any further act shall be the successor Trustee, if
such corporation or association complies with Section 7.10.

                  Section 7.10. ELIGIBILITY: DISQUALIFICATION. This Indenture
shall always have a Trustee who satisfies the requirements of TIA ss. 310(a)(l).
The Trustee shall have (or, in the case of a corporation included in a bank
holding company system, the related bank holding company subsidiary shall have)
a combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee also shall comply with
TIA ss. 310(b).

                                       61
<PAGE>

                  Section 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE
COMPANY. The Trustee is subject to TIA ss. 311(a), excluding from the operation
of TIA ss. 311(a) any creditor relationship listed in TIA ss. 311(b). A Trustee
who has resigned or been removed shall be subject to TIA ss. 311(a) to the
extent indicated therein.

                  Section 7.12. DUTIES OF TRUSTEE. (A) If an Event of Default
has occurred and is continuing, the Trustee shall exercise such of the rights
and powers vested in it by this Indenture and use the same degree of care and
skill in their exercise as a prudent person would exercise or use under the
circumstances in the conduct of his own affairs.

                  (B) Except during the continuance of an Event of Default:

                    (1)    the Trustee need perform only those duties as are
         specifically set forth in this Indenture and no others and no implied
         covenants or obligation shall be read into this Indenture against the
         Trustee; and

                    (2)    in the absence of bad faith on its part, the Trustee
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and which conform to the requirements
         of this Indenture; however, in the case of any such certificates or
         opinions which by any provision hereof are specifically required to be
         furnished to the Trustee, the Trustee shall examine the certificates
         and opinions to determine whether or not they conform to the
         requirements of this Indenture.

                  (C) The Trustee shall not be relieved from liability for its
own negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                    (1)    this paragraph does not limit the effect of paragraph
         (B) of this Section 7.12;

                    (2)    the Trustee shall not be liable for any error of
         judgment made in good faith by a Trust Officer, unless it is proved
         that the Trustee was negligent in ascertaining the pertinent facts; and

                    (3)    the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.05.

                  (D) No provision of this Indenture shall require the Trustee
to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder or in the exercise of any of its
rights or powers if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

                  (E) Every provision of this Indenture that in any way relates
to the Trustee is subject to Sections 7.12(A), (B), (C) and (D).

                                  ARTICLE VIII

                       DISCHARGE OF INDENTURE; DEFEASANCE

                  Section 8.01. DISCHARGE OF LIABILITY ON SECURITIES;
DEFEASANCE. (a) This Indenture, subject to Sections 8.01(c) and 8.06, will be
discharged and will cease to be of further effect as to all Securities issued
hereunder, when:

                    (1)    either (a) all Securities that have been
         authenticated (except lost, stolen or destroyed Securities that have
         been replaced or paid and Securities for whose payment money has
         theretofore been deposited in trust and thereafter repaid to the
         Company as provided in Section 8.04) have been delivered to the Trustee
         for cancellation; or (b) (i) all Securities that have not theretofore
         been delivered to the Trustee for cancellation have become due and
         payable by reason of the giving of a notice of redemption or otherwise
         or will become due and payable within one year and (ii) the Company or
         any Guarantor has irrevocably deposited or caused to be deposited with
         the Trustee as trust funds in trust solely for the benefit of the
         Holders, cash in U.S. Dollars sufficient, or U.S. Government
         Obligations the principal of and interest on which shall be sufficient,
         or a combination thereof, in such amounts as will be sufficient (in the
         opinion of a nationally recognized firm of independent public
         accountants expressed in a written certification thereof delivered to
         the Trustee) without consideration of any reinvestment of any interest
         thereon, to pay and discharge the entire indebtedness on such
         Securities not theretofore delivered to the Trustee for cancellation
         for principal, premium and Special Interest, if any, and accrued and
         unpaid interest to the date of Stated Maturity or redemption;

                    (2)    no Default or Event of Default shall have occurred
         and be continuing on the date of the deposit described in clause (1) of
         this paragraph (a) or shall occur as a result of such deposit and such
         deposit will not result in a breach or violation of, or constitute a
         default under, any other instrument to which the Company or any
         Guarantor is a party or by which the Company or any Guarantor is bound;

                    (3)    the Company or any Guarantor has paid or caused to be
         paid all sums payable by it under this Indenture; and

                                       63
<PAGE>

                    (4)    the Company has delivered irrevocable instructions to
         the Trustee under this Indenture to apply the deposited money toward
         the payment of the Securities at maturity or the redemption date, as
         the case may be.

In addition, the Company must deliver an Officers' Certificate and an Opinion of
Counsel to the Trustee, which complies with Section 12.05 and which states that
all conditions precedent to satisfaction and discharge have been satisfied.

                  The Trustee shall acknowledge satisfaction and discharge of
this Indenture on demand of the Company accompanied by an Officers' Certificate
and an Opinion of Counsel as to the satisfaction of all conditions to such
satisfaction and discharge of this Indenture and at the cost and expense of the
Company.

                  (b) Subject to Sections 8.01(c), 8.02 and 8.06, the Company
may at any time terminate (i) all its obligations and all obligations of the
Guarantors under the Securities and this Indenture ("LEGAL DEFEASANCE"), or (ii)
its obligations under Sections 4.06, 4.09 through 4.18, inclusive, and the
operation of Section 6.01(3), 6.01(4), 6.01(5), 6.01(6), 6.01(7) (with respect
only to Significant Subsidiaries) and 6.01(8) and the limitations contained in
Section 5.01(a)(3) and (4) ("COVENANT DEFEASANCE").

                  The Company may exercise its legal defeasance option
notwithstanding its prior exercise of its covenant defeasance option. If the
Company exercises its legal defeasance option, payment of the Securities may not
be accelerated because of an Event of Default with respect thereto. If the
Company exercises its covenant defeasance option, payment of the Securities may
not be accelerated because of an Event of Default specified in Section 6.01(3),
6.01(4), 6.01(5), 6.01(6), 6.01(7) (with respect only to Significant
Subsidiaries) or 6.01(8) or because of the failure of the Company to comply with
clause (3) or (4) in Section 5.01(a).

                  Upon satisfaction of the conditions set forth herein and upon
request of the Company, the Trustee shall acknowledge in writing the discharge
of those obligations that the Company terminates.

                  (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 7.07, 7.08, 8.04, 8.05 and
8.06 and each Guarantor's Guarantee of such obligations under its Subsidiary
Guarantee shall survive until the Securities have been paid in full. Thereafter,
the Company's obligations in Sections 7.07, 8.04 and 8.05 shall survive.

                  Section 8.02. CONDITIONS TO DEFEASANCE. The Company may
exercise its legal defeasance option or its covenant defeasance option only if:

                    (1)    the Company irrevocably deposits in trust (the
         "DEFEASANCE TRUST") with the Trustee money or U.S. Government
         Obligations for the payment of principal and interest (if any) on the
         Securities to redemption or maturity, as the case may be;

                    (2)    the Company delivers to the Trustee a certificate
         from a nationally recognized firm of independent accountants expressing
         their opinion that the payments of principal and interest when due and
         without reinvestment on the deposited U.S.

                                       64
<PAGE>

         Government Obligations plus any deposited money without investment will
         provide cash at such times and in such amounts as will be sufficient to
         pay principal and interest, if any, when due on all the Securities to
         maturity or redemption, as the case may be;

                    (3)    no Default has occurred and is continuing on the date
         of such deposit and after giving effect thereto;

                    (4)    the deposit does not constitute a default under any
         other agreement binding on the Company;

                    (5)    the Company delivers to the Trustee an Opinion of
         Counsel to the effect that the trust resulting from the deposit does
         not constitute, or is qualified as, a regulated investment company
         under the Investment Company Act of 1940;

                    (6)    the Company delivers to the Trustee an Opinion of
         Counsel stating that the Securityholders will not recognize income,
         gain or loss for federal income tax purposes as a result of such
         deposit and defeasance and will be subject to federal income tax on the
         same amount and in the same manner and at the same times as would have
         been the case if such deposit and defeasance had not occurred, and, in
         the case of legal defeasance only, such Opinion of Counsel shall be
         based on a ruling received from or published by the Internal Revenue
         Service or a change, since the date of this Indenture, in the
         applicable federal income tax law, and

                    (7)    the Company delivers to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent to the defeasance and discharge of the Securities as
         contemplated by this Article VIII have been complied with.

                  Notwithstanding the foregoing provisions of this Section, the
conditions set forth in the foregoing paragraphs (2), (3), (4), (5), (6) and (7)
need not be satisfied so long as, at the time the Company makes the deposit
described in paragraph (1), (i) no Default under Section 6.01(1), 6.01(2),
6.01(7) or 6.01(8) has occurred and is continuing on the date of such deposit
and after giving effect thereto and (ii) either (x) a notice of redemption has
been mailed pursuant to Section 3.03 providing for redemption of all the
Securities 30 days after such mailing and the provisions of Section 3.01 with
respect to such redemption shall have been complied with or (y) the Stated
Maturity of all of the Securities will occur within 30 days. If the conditions
of the preceding sentence are satisfied the Company shall be deemed to have
exercised its covenant defeasance option.

                  Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article III and paragraph 5(a) of the Securities (including by
utilizing amounts under deposit).

                  Section 8.03. APPLICATION OF TRUST MONEY. The Trustee shall
hold in trust money or U.S. Government Obligations deposited with it pursuant to
this Article VIII. It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of and interest, if any, on the
Securities.

                                       65
<PAGE>

                  Section 8.04. REPAYMENT TO COMPANY. The Trustee and the Paying
Agent shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

                  Subject to any applicable abandoned property law, the Trustee
and the Paying Agent shall pay to the Company upon written request any money
held by them for the payment of principal and interest, if any, that remains
unclaimed for two years, and, thereafter, Securityholders entitled to the money
must look to the Company for payment as general creditors.

                  Section 8.05. INDEMNITY FOR GOVERNMENT OBLIGATIONS. The
Company shall pay and shall indemnify the Trustee against any tax, fee or other
charges imposed on or assessed against U.S. Government Obligations deposited
with the Trustee hereunder or the principal and interest received on such U.S.
Government Obligations.

                  Section 8.06. REINSTATEMENT. If the Trustee or Paying Agent is
unable to apply any money or U.S. Government Obligations in accordance with this
Article VIII by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article VIII until such time as the
Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article VIII; PROVIDED that, if the Company
has made any payment of interest, if any, on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.

                                   ARTICLE IX

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

                  Section 9.01. WITHOUT CONSENT OF HOLDERS. The Company, when
authorized by a resolution of its Board of Directors, and the Trustee may amend
or supplement this Indenture, the Securities, the Subsidiary Guarantees and the
Security Documents without notice to or consent of any Holder to:

                    (1)    cure any ambiguity, omission, defect or
         inconsistency,

                    (2)    provide for the assumption by a Surviving Person of
         the obligations of the Company (or a Guarantor, as the case may be)
         under this Indenture or any Security Document,

                    (3)    provide for uncertificated Securities in addition to
         or in place of certificated Securities (PROVIDED that the
         uncertificated Securities are issued in registered form for purposes of
         Section 163(f) of the Code, or in a manner such that the uncertificated
         Securities are described in Section 163(f)(2)(B) of the Code),

<PAGE>

                    (4)    comply with any requirement of the Commission in
         order to effect or maintain the qualification of this Indenture under
         the TIA,

                    (5)    add Subsidiary Guarantees with respect to the
         Securities or confirm and evidence the release, termination or
         discharge of any security or Subsidiary Guarantee when such release,
         termination or discharge is permitted by this Indenture,

                    (6)    secure the Securities,

                    (7)    make any change that would provide any additional
         benefits or rights to Holders or that does not adversely affect the
         rights of any Holder,

                    (8)    add any additional properties or assets as
         Collateral,

                    (9)    provide for the issuance of Additional Securities in
         accordance with this Indenture, or

                    (10)   release any Guarantor from its obligations hereunder
         in accordance with Section 10.09.

                  Notwithstanding clauses (1) through (10) above, the Company
and the Trustee may not make any change that adversely affects the rights of any
Holder.

                  Section 9.02. WITH CONSENT OF HOLDERS. Subject to Section
6.07, the Company, when authorized by resolution of its Board of Directors, and
the Trustee may amend this Indenture, the Securities or the Subsidiary
Guarantees with the written consent of the Holders of a majority in aggregate
principal amount of the Securities then outstanding, and the Holders of a
majority in aggregate principal amount of the Securities then outstanding by
written notice to the Trustee may waive future compliance by the Company with
any provision of this Indenture, the Securities or the Subsidiary Guarantees.

                  Notwithstanding the provisions of this Section 9.02, without
the consent of each Securityholder affected, an amendment or waiver, including a
waiver pursuant to Section 6.04, may not:

                  (A) change the Stated Maturity of the principal of, or any
installment of interest on, any Security or reduce the principal amount thereof,
the rate of interest thereon or any premium payable upon the redemption thereof,
or change the coin or currency in which any Security or any premium or the
interest thereon is payable, or impair the right to institute suit for the
enforcement of any such payment after the stated maturity thereof;

                  (B) reduce the percentage in principal amount of the
outstanding Securities, the consent of the Holders of which is required (x) to
modify or amend this Indenture or any Security Documents or (y) for any waiver
of compliance with certain provisions of this Indenture or certain Defaults
hereunder and their consequences provided for in this Indenture;

                  (C) modify any of the provisions relating to supplemental
indentures requiring the consent of Holders or relating to the waiver of

                                       67
<PAGE>

past defaults or relating to the waiver of certain covenants, except to increase
any such percentage of outstanding Securities required for such actions or to
provide that certain other provisions of this Indenture cannot be modified or
waived without the consent of each Holder affected thereby;

                  (D) waive a default in the payment of the principal of or
interest on any Security or modify or waive the Company's obligation to
repurchase Securities under Section 4.14 or 4.15;

                  (E) except as otherwise permitted by Article V and Section
10.08, consent to the assignment or transfer by the Company or a Guarantor of
any of its rights and obligations under this Indenture;

                  (F) make any change in this Section 9.02 or Section 6.04 or
6.07;

                  (G) modify or change any provision of this Indenture affecting
the ranking of the Securities or the Subsidiary Guarantees in a manner adverse
to the Holders (it being understood that amendments or waivers of Security
Documents or releases of Collateral do not relate to ranking);

                  (H) except as otherwise permitted under Article V and Section
10.08, consent to the assignment or transfer by the Company or a Guarantor of
any of its rights and obligations under this Indenture;

                  (I) change the time at which any note must be redeemed or
repaid in accordance with the terms of this Indenture and the Securities; or

                  (J) release any Guarantor from any of its obligations under
its Subsidiary Guarantee or this Indenture other than in accordance with the
provisions of this Indenture, or amend or modify any provision relating to such
release.

                  It shall not be necessary for the consent of the Holders under
this Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof. Any amendment, waiver or consent shall be deemed effective
upon receipt by the Trustee of the necessary consents and shall not require
execution of any supplemental indenture to be effective.

                  After an amendment or waiver under this Section 9.02 becomes
effective, the Company shall mail to the Holders of each Security affected
thereby, with a copy to the Trustee, a notice briefly describing the amendment
or waiver. Any failure of the Company to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any
such amendment, waiver or consent. Except as otherwise provided in this Section
9.02, the Holders of a majority in aggregate principal amount of the Securities
then outstanding may waive compliance in a particular instance by the Company
with any provisions of this Indenture or the Securities.

                  Section 9.03. REVOCATION AND EFFECT OF CONSENTS. Until an
amendment, supplement or waiver becomes effective, a consent to it by a Holder
is a continuing consent by such Holder and every subsequent Holder of a Security
or portion of a Security that evidences

                                       68
<PAGE>

the same debt as the consenting Holder's Security, even if notation of the
consent is not made on any Security. However, any such Holder or subsequent
Holder may revoke the consent as to his Security or portion of a Security. Such
revocation shall be effective only if the Trustee receives the notice of
revocation before the date the amendment, supplement or waiver becomes
effective.

                  After an amendment, supplement or waiver becomes effective in
accordance with the terms hereof, it shall bind every Securityholder; PROVIDED
that if such amendment, supplement or waiver makes a change described in any of
clauses (A) through (J) of Section 9.02, such amendment, supplement or waiver
shall bind each Holder of a Security who has consented to it; and PROVIDED,
FURTHER, that if notice of such amendment, supplement or waiver is reflected on
a Security that evidences the same debt as the consenting Holder's Security,
such amendment, supplement or waiver shall bind every subsequent Holder of a
Security or portion of a Security that evidences the same debt as the consenting
Holder's Security.

                  Section 9.04. RECORD DATE. The Company shall be permitted to
set a record date for purposes of determining the identity of Securityholders
entitled to vote or consent on any matter arising under this Indenture. In the
Company's sole discretion, the record date shall be either (i) the record date
as determined pursuant to ss. 316(c) of the TIA or (ii) such other record date
as the Company shall select.

                  Section 9.05. NOTATION ON OR EXCHANGE OF SECURITIES. If an
amendment, supplement or waiver changes the terms of a Security, the Trustee may
(and, at the request of the Company, shall) require the Holder of the Security
to deliver it to the Trustee. The Trustee may (and, at the request of the
Company, shall) place an appropriate notation on the Security about the changed
terms and return it to the Holder and the Trustee may (and, at the request of
the Company, shall) place an appropriate notation on any Security thereafter
authenticated. Alternatively, if the Company or the Trustee so determines, the
Company in exchange for the Security shall issue and the Trustee shall
authenticate a new Security that reflects the changed terms.

                  Section 9.06. TRUSTEE MAY SIGN AMENDMENTS, ETC. The Trustee
shall sign any amendment, supplement or waiver authorized pursuant to this
Article IX if the amendment, supplement or waiver does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign it. In signing or refusing to sign such
amendment, supplement or waiver, the Trustee shall be entitled to receive and,
subject to TIA ss. 315(a) through (d), shall be fully protected in relying upon,
an Officers' Certificate and an Opinion of Counsel as conclusive evidence that
such amendment, supplement or waiver is authorized or permitted by this
Indenture, that it is not inconsistent herewith, and that it will be valid and
binding upon the Company and enforceable against the Company in accordance with
its terms.

                  Section 9.07. COMPLIANCE WITH TIA. Every amendment or
supplement to this Indenture or Securities shall comply with the TIA as then in
effect.

                  Section 9.08. AMENDMENT TO THE COLLATERAL AGENT AGREEMENT. The
Company shall not enter into any modification or amendment of the Collateral
Agent Agreement that materially adversely affects the rights of any Holder
without the written consent of the Trustee.

                                   ARTICLE X

                              SUBSIDIARY GUARANTEES

                  Section 10.01. GUARANTEE. Subject to Section 10.07, each
Guarantor, jointly and severally, hereby unconditionally and irrevocably
guarantees to each Holder and, with respect only to clause (b) below, to the
Trustee (a "SUBSIDIARY GUARANTEE"), the following obligations: (a) the full and
punctual payment of principal, premium, if any, and interest on the Securities
when due, whether at maturity, by acceleration, by redemption or otherwise, and
all other monetary obligations of the Company under this Indenture and the
Securities and (b) the full and punctual performance within applicable grace
periods of all other obligations of the Company under this Indenture (including,
without limitation, the compensation and other payment obligations to the
Trustee hereunder) and the Securities (all the foregoing being hereinafter
collectively called the "GUARANTEED OBLIGATIONS"). Each Guarantor further agrees
that the Guaranteed Obligations may be extended or renewed, in whole or in part,
without notice or further assent from such Guarantor and that such Guarantor
will remain bound under the terms hereof notwithstanding any extension or
renewal of any Guaranteed Obligation.

                  Each Guarantor agrees that its Subsidiary Guarantee herein
constitutes a guarantee of payment, performance and compliance when due (and not
a guarantee of collection) and waives any right to require that any resort be
had by any Holder or the Trustee to any security held for payment of the
Guaranteed Obligations.

                  Each Guarantor hereby agrees that its obligations hereunder
shall be as if it was principal debtor and not merely surety. The obligations of
each Guarantor hereunder are independent of the obligations of any other
Guarantor, the Company, any Subsidiary thereof or any other Person, and, subject
to Section 10.05, a separate action or actions may be brought and prosecuted
against each Guarantor whether or not action is brought against any other
Guarantor, the Company, any Subsidiary thereof or any other Person and whether
or not any other Guarantor, the Company or any Subsidiary thereof be joined in
any such action or actions. Any payment by the Company or any Subsidiary thereof
or other circumstance which operates to toll any statute of limitations as to
the Company or any such Subsidiary shall operate to toll the statute of
limitations as to each Guarantor.

                  So long as the exercise of such right does not impair the
rights of any Holder under any Subsidiary Guarantee, each Guarantor that makes a
payment or distribution under a Subsidiary Guarantee shall have the right to
seek contribution from each other Guarantor in an amount PRO RATA, based on the
net assets of each Guarantor determined in accordance with GAAP.

                  Section 10.02. UNCONDITIONAL OBLIGATIONS. The obligations of
each Guarantor hereunder shall not be discharged except by complete performance
of the Guaranteed Obligations as contemplated in this Indenture and the
Securities. The obligations of each Guarantor hereunder shall not be affected by
(a) the failure of any Holder or the Trustee to assert any claim or demand or to
enforce any right or remedy against the Company or any other Person under this
Indenture, the Securities or any other agreement or otherwise; (b) any extension
or renewal of any agreement referred to in clause (a) of this paragraph; (c) any
rescission, waiver,

                                       70
<PAGE>

amendment or modification of any of the terms or provisions of this Indenture,
the Securities or any other agreement; (d) the release of any security held by
any Holder or the Trustee for the Guaranteed Obligations or any of them; (e) the
failure of any Holder or Trustee to exercise any right or remedy against any
other Guarantor of the Guaranteed Obligations or any other Person; or (f) except
as provided in Section 10.08, any change in the ownership of such Guarantor;
PROVIDED, HOWEVER, that, notwithstanding the foregoing, no such extension,
renewal, rescission, waiver, amendment or modification shall, without the
written consent of the Guarantors, increase the principal amount of a Security
or the interest rate thereon or change the currency of payment with respect to
any Security, or alter the Stated Maturity thereof. Each Guarantor hereby waives
notice of acceptance of its Subsidiary Guarantee herein and notice of any
liability to which it may apply, and waives promptness, diligence, presentment,
demand of payment, protest, notice of dishonor or any right to require a
proceeding or the taking of other action by the Trustee or any Holder against,
and any other notice to, any other Guarantor or the Company.

                  Section 10.03. CONTINUING GUARANTEE. Each Guarantor's
Subsidiary Guarantee herein is a continuing one and all liabilities to which it
applies or may apply under the terms hereof shall be conclusively presumed to
have been created in reliance hereon. No failure or delay on the part of any
Holder in exercising any right, power or privilege hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any right, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
expressly specified are cumulative and not exclusive of any rights or remedies
which any Holder would otherwise have. No notice to or demand on any Guarantor
in any case shall entitle such Guarantor to any other further notice or demand
in similar or other circumstances or constitute a waiver of the rights of any
Holder to any other or further action to any circumstances without notice or
demand. It is not necessary for any Holder to inquire into the capacity or
powers of the Company or any Subsidiary thereof or the officers, directors,
partners or agents acting or purporting to act on its behalf, and any
indebtedness made or created in reliance upon the professed exercise of such
powers shall be guaranteed hereunder.

                  Section 10.04. SUBROGATION; ACCELERATION. Each Guarantor
agrees that it shall not be entitled to any right of subrogation in respect of
any Guaranteed Obligations until payment in full of all Guaranteed Obligations.
Each Guarantor further agrees that, as between it, on the one hand, and the
Holders and the Trustee, on the other hand, (x) the maturity of the Guaranteed
Obligations may be accelerated as provided in Article VI for the purposes of
such Guarantor's Subsidiary Guarantee herein, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the
Guaranteed Obligations, and (y) in the event of any declaration of acceleration
of such obligations as provided in Article VI, such Guaranteed Obligations
(whether or not due and payable) shall forthwith become due and payable by each
Guarantor for the purposes hereof.

                  Section 10.05. ENFORCEMENT. Except as provided in Article VI,
the Holders agree that each Guarantor's obligations hereunder may be enforced
only by the action of the Trustee in accordance with the terms of this Indenture
and that no other Holder shall have any right individually to seek to enforce
the obligations of the Guarantors hereunder. The Holders further agree that each
Guarantor's obligations hereunder may not be enforced against any

                                       71
<PAGE>

director, officer, employee, or stockholder of any Guarantor (except to the
extent such stockholder is also a Guarantor hereunder).

                  Section 10.06. COVENANTS. Each Guarantor agrees that its
Guaranteed Obligations hereunder are senior Indebtedness of such Guarantor and
such Guaranteed Obligations shall not be subordinate to any existing or future
obligations of such Guarantor. Each Guarantor further covenants and agrees that
on and after the date hereof such Guarantor will comply (as a Recourse
Subsidiary of the Company), and will cause each of its Subsidiaries to comply,
with all of the applicable provisions, covenants and agreements contained in
this Indenture, and will take, or will refrain from taking, as the case may be,
all actions that are necessary to be taken or not taken so that it is not in
violation of any provision, covenant or agreement contained in this Indenture,
and so that no Default or Event of Default, is caused by the actions of such
Guarantor or any of its Subsidiaries.

                  Each Guarantor hereby jointly and severally agrees to pay all
reasonable out-of-pocket costs and expenses of the Trustee in connection with
the enforcement of its obligations hereunder and in connection with any
amendment, waiver or consent relating hereto (including in each case, without
limitation, the reasonable fees and disbursements of counsel employed by the
Trustee).

                  Section 10.07. LIMITATION LIABILITY. Each Guarantor hereby
confirms that it is its intention that its Subsidiary Guarantee herein not
constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy
Law, the Uniform Fraudulent Conveyance Act or any similar Federal, state or
foreign law for the relief of debtors. Accordingly, each Guarantor hereby
irrevocably agrees that the Guaranteed Obligations guaranteed by such Guarantor
shall be limited to the maximum amount which, after giving effect to such
maximum amount and all other (contingent or otherwise) liabilities of such
Guarantor that are relevant under such laws, and after giving effect to any
rights to contribution pursuant to any agreement providing for an equitable
contribution among such Guarantor and the other Guarantors, will result in the
Guaranteed Obligations of such Guarantor in respect of its Subsidiary Guarantee
not constituting a fraudulent transfer or conveyance under federal or state law.

                  Section 10.08. WHEN THE GUARANTORS MAY MERGE, ETC. Company
shall not permit any Guarantor to consolidate with or merge with or into, or
sell, assign, transfer, or lease all or substantially all of its properties and
assets (either in one transaction or a series of related transactions) to, any
Person unless:

                    (1)    the other Person is the Company or any Wholly Owned
         Recourse Subsidiary that is a Guarantor or becomes a Guarantor
         concurrently with the transaction; or

                    (2)    (1) either (x) the Guarantor shall be the resulting,
         surviving or transferee Person or (y) the resulting, surviving or
         transferee Person expressly assumes the Guarantor's Subsidiary
         Guarantee and all the obligations of such Guarantor under the
         Securities, this Indenture, the Subsidiary Guarantee and the Security
         Documents (each of which shall remain in full force and effect); and
         (2) the resulting, surviving or transferee Person, if other than the
         Guarantor, is a corporation or limited liability company

                                       72
<PAGE>

         organized under the laws of the United States, any state thereof or the
         District of Columbia and immediately after giving effect to the
         transaction and any related Issuance of Debt of, no Default or Event of
         Default shall have occurred and be continuing; or

                    (3)    the transaction constitutes a sale or other
         disposition (including by way of consolidation or merger) of the
         Guarantor or the sale or disposition of all or substantially all the
         assets of the Guarantor (in each case other than to another Guarantor)
         and at the time of such transaction after giving PRO FORMA effect
         thereto, the provisions of clause (2) of Section 5.01(a) would be
         satisfied and the transaction is otherwise permitted by this Indenture.

                  In connection with any consolidation, merger, sale,
assignment, transfer or lease contemplated by this Section 10.08, the Company
shall deliver, or cause to be delivered, to the Trustee, in form and substance
reasonably satisfactory to the Trustee, an Officers' Certificate and an Opinion
of Counsel, each stating that such consolidation, merger, sale, assignment,
transfer or lease and the supplemental indenture in respect thereto comply with
this Section 10.08 and the TIA and that all conditions precedent herein provided
for relating to such transaction have been complied with.

                  Upon any consolidation or merger or any sale, assignment,
transfer or lease of all or substantially all of the assets of the Guarantor in
accordance with this Section 10.08, the successor corporation formed by such
consolidation or into which the Guarantor is merged or to which such sale,
assignment, transfer or lease is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Guarantor under the Subsidiary
Guarantee with the same effect as if such successor corporation had been named
as the Guarantor therein.

                  Section 10.09. RELEASE OF GUARANTOR. The Subsidiary Guarantee
of each Guarantor will be released and such Guarantor will be relieved of any
obligations under its Subsidiary Guarantee:

                    (1)    in the event of a sale or other disposition, by way
         of merger, consolidation or otherwise, of all the Capital Stock of such
         Guarantor to any Person that is not an Affiliate of the Company;
         PROVIDED that the Net Cash Proceeds from such sale or other disposition
         is applied in accordance with the applicable provisions of Section
         4.15;

                    (2)    upon the repayment in full, release or discharge of
         Debt or the retirement of Preferred Stock, in each case that resulted
         in the creation of the Subsidiary Guarantee of such Guarantor; and

                    (3)    upon the release or discharge of another Guarantee
         that resulted in the creation of the Subsidiary Guarantee of such
         Guarantor, except a release or discharge by or as a result of payment
         under such other Guarantee.

In each such case, prior to release and discharge of such Subsidiary Guarantee,
the Company will have delivered to the Trustee an Officers' Certificate and an
Opinion of Counsel, each stating that, as required by Section 12.04, all
conditions precedent herein provided for relating to such transactions have been
complied with and that such release is authorized and permitted hereunder.

                                       73
<PAGE>

                  The Trustee shall execute any documents reasonably requested
by either the Company or a Guarantor in order to evidence the release of such
Guarantor from its obligations under its Subsidiary Guarantee under this Article
X.

                  Section 10.10. MISCELLANEOUS. (a) Each Subsidiary Guarantee
shall be binding upon the respective Guarantor and its successors and assigns
and shall inure to the benefit of the Holders and the Trustee and their
respective successors and assigns and, in the event of any transfer or
assignment of rights by any Holder or the Trustee, the rights and privileges
under the Subsidiary Guarantees conferred upon that party shall automatically
extend to and be vested in such transferee or assigns, all subject to the terms
and conditions of this Indenture.

                  (b) All notices, requests, demands or other communications
pursuant to this Article X shall be made in accordance with Section 12.02 of
this Indenture.

any, or interest, if any, on a Security is rescinded or must otherwise be
restored or returned upon insolvency, bankruptcy or reorganization of the
Company, each Guarantor's obligations hereunder with respect to such payments
shall be reinstated as of the date of such rescission, restoration or returns as
though such payment had become due but had not been made at such times.

                  Section 10.11. EXECUTION AND DELIVERY OF NOTATION OF
SUBSIDIARY GUARANTEE. To evidence its Subsidiary Guarantee set forth in Section
10.01, each Guarantor hereby agrees that a notation of such Subsidiary Guarantee
substantially in the form included in Exhibit H shall be endorsed by an Officer
of such Guarantor on each Security authenticated and delivered by the Trustee
and that this Indenture shall be executed on behalf of such Guarantor by an
Officer of such Guarantor.

                  Each Guarantor hereby agrees that its Subsidiary Guarantee set
forth in Section 10.01 shall remain in full force and effect notwithstanding any
failure to endorse on each Security a notation of such Subsidiary Guarantee.

                  If an Officer whose signature is on this Indenture or on a
notation of such Subsidiary Guarantee no longer holds that office at the time
the Trustee authenticates the Security on which a Subsidiary Guarantee is
endorsed, the Subsidiary Guarantee shall be valid nevertheless.

                  The delivery of any Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of the
Subsidiary Guarantee set forth in this Indenture on behalf of the Guarantors.

                  Section 10.12. ADDITIONAL GUARANTORS. The Company covenants
and agrees that it shall cause any Person which becomes obligated to become a
Guarantor, pursuant to the terms of Section 4.16 or 4.18, to (1) execute and
deliver to the Trustee a supplemental indenture and any other documentation
requested by the Trustee, in each case in form reasonably satisfactory to the
Trustee in accordance with Section 4.16 or 4.18, as the case may be, pursuant to
which such Person shall unconditionally Guarantee, on a senior basis, all of the
obligations of the Company under the Securities and this Indenture in accordance
with this Article X with the

                                       74
<PAGE>

same effect and to the same extent as if such Person had been named herein as a
Guarantor and (2) deliver to the Trustee an Opinion of Counsel that such
supplemental indenture has been duly executed and delivered by such Person and
is valid and binding upon such Person and enforceable against such Person in
accordance with its terms.

the Securities and the Subsidiary Guarantees, consents and agrees to the terms
of the Security Documents (including, without limitation, the provisions
providing for foreclosure and release of Collateral) as the same may be in

Security Documents, to assure and confirm to the Trustee and the Collateral
Agent the security interest in the Collateral contemplated hereby, by the
Security Documents or any part thereof, as from time to time constituted, so as
to render the same available for the security and benefit of this Indenture and
of the Securities and the Subsidiary Guarantees secured thereby, according to
the intent and purposes herein and therein expressed. The Company shall take and
shall cause the Guarantors to take, upon request of the Trustee, any and all
actions reasonably required to cause the Security Documents to create and
maintain, as security for the obligations of the Company and the Guarantors
hereunder, for so long as the Securities are to be secured as provided in the
Security Documents, a valid and enforceable perfected lien on and security
interest in all the Collateral, in favor of the Collateral Agent for the benefit
of the Trustee, the Holders and other Persons for whose benefit the Collateral
Agent acts pursuant to the Security Documents. Each of the Company and the
Guarantors covenants and agrees that it shall execute, acknowledge and deliver
to the Collateral Agent such further assignments, transfers, assurances or other
instruments and shall do or cause to be done all such acts and things as may be

Securities.

mortgages and any instruments of further assurance, in such manner and in such
places as may be required by law fully to preserve and protect the rights of the
Holders and the Trustee under this Indenture and the Security Documents to all

shall from time to time promptly pay all financing, continuation statement and
mortgage recording, registration and/or filing fees, charges and taxes relating
to this Indenture and the Security Documents, any amendments thereto and any
other instruments of further assurance required hereunder or pursuant to the
Security Documents. The Trustee shall have no obligation to, nor shall it be
responsible for any failure to, so register, file or record.

in accordance with the terms thereof and the Securities are to be secured by the
Collateral, the Company shall deliver to the Trustee on the Issue Date and,
thereafter, on July 15 of each year (commencing within July 15, 2005), an
Opinion of Counsel either (1) stating that in the opinion of such counsel, such
action has been taken with respect to the recording, registering, filing,
re-recording, re-registering and re-filing of this Indenture and any Security

substituted only in accordance with the terms of the Security Documents.

                  (b) The release of any Collateral from the terms of this
Indenture and the Security Documents shall not be deemed to impair the security
under this Indenture in contravention of the provisions hereof if and to the
extent the Collateral is released pursuant to the terms of the Security
Documents and this Indenture.

                  Section 11.04. CERTIFICATES AND OPINIONS OF COUNSEL. (a). To
the extent applicable, the Company will furnish to the Trustee and the
Collateral Agent, prior to each proposed release of Collateral pursuant to the
Security Documents:

         and

                    (2)    An Opinion of Counsel to the effect that such
         accompanying documents constitute all documents required by Section
         314(d) of the TIA.

                  (b) The Trustee may, to the extent permitted by Sections 7.01
and 7.12 hereof, accept as conclusive evidence of compliance with the foregoing
provisions the appropriate statements contained in such documents and such
Opinion of Counsel.

                  Section 11.05. AUTHORIZATION OF ACTIONS TO BE TAKEN BY THE
TRUSTEE UNDER THE SECURITY DOCUMENTS. Subject to the provisions of Sections 7.01
and 7.12 and Article IX, the provisions of the Security Documents and any
applicable provisions of the TIA, the Trustee may, in its sole discretion and
without the consent of the Holders of Securities, take, on behalf of the Holders
of Securities, or direct, on behalf of the Holders of Securities, the Collateral
Agent to take, all actions it deems necessary or appropriate in order to (1)
enforce any of the terms of the Security Documents and (2) collect and receive
any and all amounts payable in respect of the obligations of the Company
hereunder. Subject to the provisions of the Security Documents, the Trustee
shall have power to institute and maintain such suits and proceedings as it may
deem expedient to prevent any impairment of the Collateral by any acts that may
be unlawful or in violation of the Security Documents or this Indenture, and
such suits and proceedings as the Trustee may deem expedient to preserve or
protect its interests and the interests of the Holders in the Collateral
(including power to institute and maintain suits or proceedings to restrain the
enforcement of or compliance with any legislative or other governmental
enactment, rule or order that may be unconstitutional or otherwise invalid if
the enforcement of, or compliance with, such enactment, rule or order would
impair the security interest hereunder or be prejudicial to the interests of the
Holders or to the Trustee).

TRUSTEE UNDER THE SECURITY DOCUMENTS. The Trustee is authorized to receive any

payment in full of the principal of, accrued and unpaid interest and Special
Interest, if any, on the Securities and all other Obligations under the
Securities and this Indenture and all obligations under the Security Documents
that are due and payable at or prior to the time such principal, accrued and
unpaid interest and Special Interest, if any, are paid, (2) a satisfaction and
discharge of this Indenture as described in Article VIII or (3) a legal
defeasance or covenant defeasance as described in Article VIII, the Trustee
will, at the request of the Company, deliver a certificate to the Collateral
Agent stating that such obligations have been paid in full, and instruct the
Collateral Agent to release the Liens securing the Obligations pursuant to this
Indenture and the Security Documents. Upon receipt of such instruction, the
Trustee, if it is the Collateral Agent, shall, or, if it is not the Collateral
Agent, shall request the Collateral Agent to, execute, deliver or acknowledge
any necessary or proper instruments of termination, satisfaction or release to
evidence the release of all such Liens.

           [FORM OF REVERSE SIDE INITIAL SECURITY/ADDITIONAL SECURITY]

                    BUILDING MATERIALS CORPORATION OF AMERICA

                           7.75% Senior Notes due 2014

                  1. INTEREST. BUILDING MATERIALS CORPORATION OF AMERICA, a
Delaware corporation (the "COMPANY"), promises to pay cash interest on the
principal amount of this Security at a rate of 7.75% per annum, payable on
February 1 and August 1 of each year (the "INTEREST PAYMENT DATE"), commencing
February 1, 2005. The Company shall pay interest on overdue principal and, to
the fullest extent permitted by law, on overdue interest, in each case at the
rate of 7.75% per annum, as provided in the Indenture. Interest will be computed
on the basis of a 360-day year of twelve 30-day months.

                  2. METHOD OF PAYMENT. The Company shall pay interest on the
Securities (except defaulted interest) to the persons who are the registered
Holders at the close of business on January 15 or July 15 (the "RECORD DATE")
immediately preceding the Interest Payment Date even if the Securities are
canceled on registration of transfer or registration of exchange after such
Record Date. The Holder must surrender this Security to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money
of the United States that at the time of payment is legal tender for payment of
public and private debts. The Company, however, may pay principal and interest
by a check payable in such money. The Company may mail an interest check to the
Holder's registered address. If a payment date is a Legal Holiday at a place of
payment, payment may be made at that place on the next succeeding day that is
not a Legal Holiday, and no interest shall accrue for the intervening period.

                  3. PAYING AGENT AND REGISTRAR. Initially, Wilmington Trust
Company (the "TRUSTEE") or its agent will act as Paying Agent and Registrar. The
Company may change any Paying Agent, Registrar or co-Registrar without prior
notice to any Holder. The Company or any of its Subsidiaries or Affiliates may
act in any such capacity, except in certain circumstances.

                  4. INDENTURE. The Company issued the Securities under an
Indenture dated as of July 26, 2004 (the "INDENTURE") among the Company, the
Guarantors, and the Trustee. Capitalized terms used in this Security and not
defined in this Security shall have the meaning set forth in the Indenture. The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 as in
effect on the date of the Indenture. The Securities are subject to all such
terms, and Holders of Securities are referred to the Indenture and said Act for
a statement of such terms. The obligations of the Company under the Indenture
and the Securities are guaranteed by the Guarantors.

                  [The Securities are senior obligations of the Company and are
issued in an initial aggregate principal amount of $200,000,000. Additional
Securities may be issued in an unlimited amount, subject to Section 4.09 and
other provisions of the Indenture. This Security is one of the Initial
Securities referred to in the Indenture. The Securities include the Initial
Securities, any Additional Securities and any Exchange Securities issued in
exchange for the Initial Securities and the Additional Securities, if any. The
Initial Securities, the Additional

                                      A-4
<PAGE>

Securities and the Exchange Securities are treated as a single class of
securities under the Indenture.]*

                  5. REDEMPTION. (a) OPTIONAL REDEMPTION. In the event a Change
of Control occurs, and Holders do not require the Company to purchase all
outstanding Securities as described in Section 4.14 of the Indenture, the
Company may purchase all, but not less than all, of the Securities outstanding
subsequent to the Change of Control Payment Date in respect of such Change of
Control, at a redemption price equal to the sum of (x) 100% of the principal
amount thereof plus accrued and unpaid interest thereon to the redemption date,
and (y) the Applicable Premium with respect to each $1,000 principal amount of
Securities so redeemed (the "CALL PRICE"). Notice of any redemption to be made
pursuant to this paragraph 5 as a result of the occurrence of a Change of
Control must be given no later than 10 days after the Change of Control Payment
Date applicable to the Change of Control giving rise to such redemption, and
redemption must be made within 30 days of the date of such notice.

                  (b) MANDATORY REDEMPTION. The Securities will not have the
benefit of any sinking fund.

                  6. PUT PROVISIONS. Upon a Change of Control, any Holder of
Securities will have the right to cause the Company to repurchase all or any
part of the Securities (in integral multiples of $1,000) of such Holder at a
repurchase price equal to 101% of the principal amount thereof, plus accrued
interest to the date of repurchase as provided in, and subject to the terms of,
the Indenture.

                  7. NOTICE OF REDEMPTION. Notice of redemptions pursuant to
paragraph 5 will be mailed at such time as is provided by paragraph 5(a) to each
Holder of Securities to be redeemed at the Holder's registered address. If money
sufficient to pay the redemption price and accrued interest on all Securities to
be redeemed on the redemption date is deposited with the Paying Agent on the
redemption date, on and after such date interest will cease to accrue on such
Securities.

                  8. PROCEEDS ON DISPOSITION OF ASSETS. As described in Section
4.15 of the Indenture, the Company is required under certain circumstances to
apply the Net Cash Proceeds (or a portion thereof) from Asset Sales to offer to
purchase Securities at a price equal to 100% of the principal amount thereof
plus accrued interest thereon to the date of purchase.

                  9. DENOMINATIONS, TRANSFER, EXCHANGE. The Securities are in
registered form in denominations of $1,000 and integral multiples of $1,000. A
Holder may register the transfer or exchange of Securities as provided in the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents, provide certain certifications
and legal opinions as described herein and to pay any taxes and fees required by
law or permitted by the Indenture.

                  10. PERSONS DEEMED OWNERS. The Company, the Trustee and any
agent of the Company or the Trustee may treat the Person in whose name the
Security is registered with the

registration rights agreement executed in connection with such Additional
Security.

<PAGE>

Registrar as the owner for all purposes.

                  11. UNCLAIMED MONEY. If money for the payment of interest or
principal remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company at its written request. After such time,
Holders entitled to the money must look to the Company for payment unless an
abandoned property law designates another Person, and all liability of the
Trustee and such Paying Agent with respect to such money shall cease.

                  12. DISCHARGE PRIOR TO MATURITY. Subject to certain conditions
described in Article VIII of the Indenture, if the Company deposits with the
Trustee money or U.S. Government Obligations sufficient to pay the principal of
and interest on the Securities to maturity, the Company will be discharged (to
the extent provided in the Indenture) from the Indenture and the Securities.

                  13. AMENDMENTS, SUPPLEMENTS AND WAIVERS. Subject to certain
exceptions requiring the consent of each Holder affected as described in Article
IX of the Indenture, the Indenture or the Securities may be amended or
supplemented with the consent of the Holders of at least a majority in principal
amount of the then outstanding Securities, and any existing Default may be
waived with the consent of the Holders of a majority in principal amount of the
then outstanding Securities. Without notice to or the consent of any Holder, the
parties thereto may amend or supplement the Indenture or the Securities to,
among other things, cure any ambiguity, defect or inconsistency, provide for the
assumption of the obligations of the Company to Holders or make any change that
does not adversely affect the rights of any Holder.

                  14. RESTRICTIVE COVENANTS. The Indenture imposes certain
limitations on, among other things, the ability of the Company to merge or
consolidate with any other Person or sell, lease or otherwise transfer all or
substantially all of its properties or assets, the ability of the Company or
certain of its Subsidiaries to make Restricted Payments and Restricted
Investments and the ability of the Company and certain of its Subsidiaries to
incur Debt, create Liens or engage in transactions with Affiliates or issue
Preferred Stock, all subject to certain limitations and qualifications described
in the Indenture.

                  15. SUCCESSOR CORPORATION. When a successor Person or other
entity assumes all the obligations of its predecessor under the Securities and
the Indenture, the predecessor Person will be released from those obligations.

                  16. DEFAULTS AND REMEDIES. The Securities have the Events of
Default as set forth in Section 6.01 of the Indenture. Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Securities may declare all the Securities to be due and payable
immediately, except that in the case of an Event of Default arising from certain
events of bankruptcy, insolvency or reorganization relating to the Company, all
outstanding Securities shall become due and payable immediately without further
action or notice. Holders may not enforce the Indenture or the Securities except
as provided in the Indenture. The Trustee may require indemnity satisfactory to
it before it enforces the Indenture or the Securities. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Securities may direct the Trustee in its exercise of any trust or power. The
Company must furnish quarterly

                                      A-6
<PAGE>

compliance certificates to the Trustee.

                  17. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee under the
Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or any of its Affiliates,
and may otherwise deal with the Company or any of its Affiliates, as if it were
not the Trustee.

                  18. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
stockholder or Affiliate, as such, of the Company shall not have any liability
for any obligations of the Company under the Securities or the Indenture or for
any claim based on, in respect of or by reason of such obligations or their
creation. Each Holder by accepting a Security waives and releases all such
liability. The waiver and release are part of the consideration for the issue of
the Securities.

                  19. AUTHENTICATION. This Security shall not be valid until
authenticated by the manual signature of the Trustee or any authenticating
agent.

                  20. ABBREVIATIONS. Customary abbreviations may be used in the
name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT

                  21. CUSIP AND ISIN NUMBERS. Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures, the
Company has caused CUSIP and ISIN numbers to be printed on the Securities and
has directed the Trustee to use CUSIP and ISIN numbers in notices of redemption
as a convenience to Securityholders. No representation is made as to the
accuracy of such numbers either as printed on the Securities or as contained in
any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.

                  22. REGISTRATION RIGHTS. [The Holder is entitled to the
benefits of the Registration Rights Agreement dated July 26, 2004, among the
Company, the Guarantors, and the Initial Purchasers (the "REGISTRATION RIGHTS
AGREEMENT"). In the event that (a) on or prior to the 90th day following the
Issue Date, the Exchange Offer Registration Statement (as defined in the
Registration Rights Agreement) has not been filed with the United States
Securities and Exchange Commission ("COMMISSION"), (b) on or prior to the 210th
day following the Issue Date, the Exchange Offer Registration Statement (as
defined in the Registration Rights Agreement) has not been declared effective,
(c) on or prior to the 240th day following the Issue Date, the Registered
Exchange Offer (as defined in the Registration Rights Agreement) has not been
consummated, (d) on or prior to the 60th day following the date the obligation
to file the Shelf Registration Statement (as defined in the Registration Rights
Agreement) arises, the Shelf Registration Statement has not been filed with the
Commission, (e) on or prior to 150th day following the date the obligation to
file arises, the Shelf Registration has not been declared effective, or (f)
after either the Exchange Offer Registration Statement or the Shelf Registration
Statement has been declared effective, such Registration Statement thereafter
ceases to be effective or usable (subject to the exceptions described in the
Registration Rights Agreement) in connection with resales of Securities or
Exchange Securities in accordance with and during the

                                      A-7
<PAGE>

periods specified in the Registration Rights Agreement (each such event referred
to in clauses (a) through (f) above, a "REGISTRATION DEFAULT"), then interest
("SPECIAL INTEREST") shall accrue on the principal amount of the Initial
Securities and the Exchange Securities (in addition to the stated interest on
the Initial Securities and the Exchange Securities) from and including the date
on which any such Registration Default shall occur to but excluding the date on
which all Registration Defaults have been cured. Special Interest shall accrue
at a rate per annum equal to 0.25% of the principal amount of the Securities
(determined daily) with respect to the first 90-day period following such
Registration Default. The rate for Special Interest shall increase by an
additional 0.25% per annum at the end of each subsequent 90-day period until
such Registration Default has been cured; PROVIDED, HOWEVER, that in no event
shall the rate of such additional interest exceed 1.00% per annum. The Company
shall pay such accrued Special Interest, if any, in cash in full on each
Interest Payment Date. Upon the cure of any Registration Default, Special
Interest with respect to such event shall cease to accrue from the date of the
filing, effectiveness or consummation that cured such event, as the case may be,
if the Company is otherwise in compliance with this paragraph. However, if,
after any such Special Interest ceases to accrue, a different Registration
Default occurs, Special Interest will again accrue as described.]*

                  The Company will furnish to any Holder upon written request
and without charge a copy of the Indenture. Request may be made to:

                    [FORM OF REVERSE SIDE EXCHANGE SECURITY]

                    BUILDING MATERIALS CORPORATION OF AMERICA

                      Series B 7.75% Senior Notes due 2014

                  1. INTEREST. BUILDING MATERIALS CORPORATION OF AMERICA, a
Delaware corporation (the "COMPANY"), promises to pay cash interest on the
principal amount of this Security at a rate of 7.75% per annum, payable on
February 1 and August 1 of each year (the "INTEREST PAYMENT DATE"), commencing
February 1, 2005. The Company shall pay interest on overdue principal and, to
the fullest extent permitted by law, on overdue interest, in each case at the
rate of 7.75% per annum, as provided in the Indenture. Interest will be computed
on the basis of a 360-day year of twelve 30-day months.

                  2. METHOD OF PAYMENT. The Company shall pay interest on the
Securities (except defaulted interest) to the persons who are the registered
Holders at the close of business on January 15 or July 15 (the "RECORD DATE")
immediately preceding the Interest Payment Date even if the Securities are
canceled on registration of transfer or registration of exchange after such
Record Date. The Holder must surrender this Security to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money
of the United States that at the time of payment is legal tender for payment of
public and private debts. The Company, however, may pay principal and interest
by a check payable in such money. The Company may mail an interest check to the
Holder's registered address. If a payment date is a Legal Holiday at a place of
payment, payment may be made at that place on the next succeeding day that is
not a Legal Holiday, and no interest shall accrue for the intervening period.

                  3. PAYING AGENT AND REGISTRAR. Initially, Wilmington Trust
Company (the "TRUSTEE") or its agent will act as Paying Agent and Registrar. The
Company may change any Paying Agent, Registrar or co-Registrar without prior
notice to any Holder. The Company or any of its Subsidiaries or Affiliates may
act in any such capacity, except in certain circumstances.

                  4. INDENTURE. The Company issued the Securities under an
Indenture dated as of July 26, 2004 (the "INDENTURE") among the Company, the
Guarantors, and the Trustee. Capitalized terms used in this Security and not
defined in this Security shall have the meaning set forth in the Indenture. The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 as in
effect on the date of the Indenture. The Securities are subject to all such
terms, and Holders of Securities are referred to the Indenture and said Act for
a statement of such terms. The obligations of the Company under the Indenture
and the Securities are guaranteed by the Guarantors.

                  [The Securities are senior obligations of the Company and were
issued in an initial aggregate principal amount of $200,000,000. Additional
Securities may be issued in an unlimited amount, subject to Section 4.09 and
other provisions of the Indenture. This Security is one of the Exchange
Securities referred to in the Indenture. The Securities include the Initial
Securities, any Additional Securities and any Exchange Securities issued in
exchange for the Initial Securities and the Additional Securities, if any. The
Initial Securities, the Exchange

                                      B-4
<PAGE>

Securities and the Additional Securities are treated as a single class of
securities under the Indenture.]*

                  5. REDEMPTION. (a) OPTIONAL REDEMPTION. In the event a Change
of Control occurs, and Holders do not require the Company to purchase all
outstanding Securities as described in Section 4.14 of the Indenture, the
Company may purchase all, but not less than all, of the Securities outstanding
subsequent to the Change of Control Payment Date in respect of such Change of
Control, at a redemption price equal to the sum of (x) 100% of the principal
amount thereof plus accrued and unpaid interest thereon to the redemption date,
and (y) the Applicable Premium with respect to each $1,000 principal amount of
Securities so redeemed (the "CALL PRICE"). Notice of any redemption to be made
pursuant to this paragraph 5 as a result of the occurrence of a Change of
Control must be given no later than 10 days after the Change of Control Payment
Date applicable to the Change of Control giving rise to such redemption, and
redemption must be made within 30 days of the date of such notice.

                  (b) MANDATORY REDEMPTION. The Securities will not have the
benefit of any sinking fund.

                  6. PUT PROVISIONS. Upon a Change of Control, any Holder of
Securities will have the right to cause the Company to repurchase all or any
part of the Securities (in integral multiples of $1,000) of such Holder at a
repurchase price equal to 101% of the principal amount thereof, plus accrued
interest to the date of repurchase as provided in, and subject to the terms of,
the Indenture.

                  7. NOTICE OF REDEMPTION. Notice of redemptions pursuant to
paragraph 5 will be mailed at such time as is provided by paragraph 5(a) to each
Holder of Securities to be redeemed at the Holder's registered address. If money
sufficient to pay the redemption price and accrued interest on all Securities to
be redeemed on the redemption date is deposited with the Paying Agent on the
redemption date, on and after such date interest will cease to accrue on such
Securities.

                  8. PROCEEDS ON DISPOSITION OF ASSETS. As described in Section
4.15 of the Indenture, the Company is required under certain circumstances to
apply the Net Cash Proceeds (or a portion thereof) from Asset Sales to offer to
purchase Securities at a price equal to 100% of the principal amount thereof
plus accrued interest thereon to the date of purchase.

                  9. DENOMINATIONS, TRANSFER, EXCHANGE. The Securities are in
registered form in denominations of $1,000 and integral multiples of $1,000. A
Holder may register the transfer or exchange of Securities as provided in the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents, provide certain certifications
and legal opinions as described herein and to pay any taxes and fees required by
law or permitted by the Indenture.

                  10. PERSONS DEEMED OWNERS. The Company, the Trustee and any
agent of the Company or the Trustee may treat the Person in whose name the
Security is registered with the

registration rights agreement executed in connection with such Additional
Security.

<PAGE>

Registrar as the owner for all purposes.

                  11. UNCLAIMED MONEY. If money for the payment of interest or
principal remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company at its written request. After such time,
Holders entitled to the money must look to the Company for payment unless an
abandoned property law designates another Person, and all liability of the
Trustee and such Paying Agent with respect to such money shall cease.

                  12. DISCHARGE PRIOR TO MATURITY. Subject to certain conditions
described in Article VIII of the Indenture, if the Company deposits with the
Trustee money or U.S. Government Obligations sufficient to pay the principal of
and interest on the Securities to maturity, the Company will be discharged (to
the extent provided in the Indenture) from the Indenture and the Securities.

                  13. AMENDMENTS, SUPPLEMENTS AND WAIVERS. Subject to certain
exceptions requiring the consent of each Holder affected as described in Article
IX of the Indenture, the Indenture or the Securities may be amended or
supplemented with the consent of the Holders of at least a majority in principal
amount of the then outstanding Securities, and any existing Default may be
waived with the consent of the Holders of a majority in principal amount of the
then outstanding Securities. Without notice to or the consent of any Holder, the
parties thereto may amend or supplement the Indenture or the Securities to,
among other things, cure any ambiguity, defect or inconsistency, provide for the
assumption of the obligations of the Company to Holders or make any change that
does not adversely affect the rights of any Holder.

                  14. RESTRICTIVE COVENANTS. The Indenture imposes certain
limitations on, among other things, the ability of the Company to merge or
consolidate with any other Person or sell, lease or otherwise transfer all or
substantially all of its properties or assets, the ability of the Company or
certain of its Subsidiaries to make Restricted Payments and Restricted
Investments and the ability of the Company and certain of its Subsidiaries to
incur Debt, create Liens or engage in transactions with Affiliates or issue
Preferred Stock, all subject to certain limitations and qualifications described
in the Indenture.

                  15. SUCCESSOR CORPORATION. When a successor Person or other
entity assumes all the obligations of its predecessor under the Securities and
the Indenture, the predecessor Person will be released from those obligations.

                  16. DEFAULTS AND REMEDIES. The Securities have the Events of
Default as set forth in Section 6.01 of the Indenture. Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Securities may declare all the Securities to be due and payable
immediately, except that in the case of an Event of Default arising from certain
events of bankruptcy, insolvency or reorganization relating to the Company, all
outstanding Securities shall become due and payable immediately without further
action or notice. Holders may not enforce the Indenture or the Securities except
as provided in the Indenture. The Trustee may require indemnity satisfactory to
it before it enforces the Indenture or the Securities. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Securities may direct the Trustee in its exercise of any trust or power. The
Company must furnish quarterly

                                      B-6
<PAGE>

compliance certificates to the Trustee.

                  17. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee under the
Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or any of its Affiliates,
and may otherwise deal with the Company or any of its Affiliates, as if it were
not the Trustee.

                  18. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
stockholder or Affiliate, as such, of the Company shall not have any liability
for any obligations of the Company under the Securities or the Indenture or for
any claim based on, in respect of or by reason of such obligations or their
creation. Each Holder by accepting a Security waives and releases all such
liability. The waiver and release are part of the consideration for the issue of
the Securities.

                  19. AUTHENTICATION. This Security shall not be valid until
authenticated by the manual signature of the Trustee or any authenticating
agent.

                  20. ABBREVIATIONS. Customary abbreviations may be used in the
name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT
(= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (=
Uniform Gifts to Minors Act).

                  21. CUSIP AND ISIN NUMBERS. Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures, the
Company has caused CUSIP and ISIN numbers to be printed on the Securities and
has directed the Trustee to use CUSIP and ISIN numbers in notices of redemption
as a convenience to Securityholders. No representation is made as to the
accuracy of such numbers either as printed on the Securities or as contained in
any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.

                  22. REGISTRATION RIGHTS. [The Holder is entitled to the
benefits of the Registration Rights Agreement dated July 26, 2004, among the
Company, the Guarantors, and the Initial Purchasers (the "REGISTRATION RIGHTS
AGREEMENT"). In the event that (a) on or prior to the 90th day following the
Issue Date, the Exchange Offer Registration Statement (as defined in the
Registration Rights Agreement) has not been filed with the United States
Securities and Exchange Commission ("COMMISSION"), (b) on or prior to the 210th
day following the Issue Date, the Exchange Offer Registration Statement (as
defined in the Registration Rights Agreement) has not been declared effective,
(c) on or prior to the 240th day following the Issue Date, the Registered
Exchange Offer (as defined in the Registration Rights Agreement) has not been
consummated, (d) on or prior to the 60th day following the date the obligation
to file the Shelf Registration Statement (as defined in the Registration Rights
Agreement) arises, the Shelf Registration Statement has not been filed with the
Commission, (e) on or prior to 150th day following the date the obligation to
file arises, the Shelf Registration has not been declared effective, or (f)
after either the Exchange Offer Registration Statement or the Shelf Registration
Statement has been declared effective, such Registration Statement thereafter
ceases to be effective or usable (subject to the exceptions described in the
Registration Rights Agreement) in connection with resales of Securities or
Exchange Securities in accordance with and during the

                                      B-7
<PAGE>

periods specified in the Registration Rights Agreement (each such event referred
to in clauses (a) through (f) above, a "REGISTRATION DEFAULT"), then interest
("SPECIAL INTEREST") shall accrue on the principal amount of the Initial
Securities and the Exchange Securities (in addition to the stated interest on
the Initial Securities and the Exchange Securities) from and including the date
on which any such Registration Default shall occur to but excluding the date on
which all Registration Defaults have been cured. Special Interest shall accrue
at a rate per annum equal to 0.25% of the principal amount of the Securities
(determined daily) with respect to the first 90-day period following such
Registration Default. The rate for Special Interest shall increase by an
additional 0.25% per annum at the end of each subsequent 90-day period until
such Registration Default has been cured; PROVIDED, HOWEVER, that in no event
shall the rate of such additional interest exceed 1.00% per annum. The Company
shall pay such accrued Special Interest, if any, in cash in full on each
Interest Payment Date. Upon the cure of any Registration Default, Special
Interest with respect to such event shall cease to accrue from the date of the
filing, effectiveness or consummation that cured such event, as the case may be,
if the Company is otherwise in compliance with this paragraph. However, if,
after any such Special Interest ceases to accrue, a different Registration
Default occurs, Special Interest will again accrue as described.]*

and without charge a copy of the Indenture. Request may be made to:
