debtor and whether or not such interest is an allowed claim in any such

under each of the Loan Documents, whether at stated maturity, by acceleration or
otherwise (all of the foregoing being herein referred to as the "Secured
Obligations"), each Pledgor hereby assigns, transfers and pledges to the
Administrative Agent for the benefit of the Secured Parties, and grants to the

                (ii)    whether or not constituting "investment property" as so
        defined, (w) all right, title and interest of each Pledgor (whether now
        or in the future) in and to the shares of Capital Stock or other equity
        interests owned by such Pledgor, which shares or other equity interests
        are listed on Schedule I annexed hereto next to such Pledgor's name,
        (collectively, the "Pledged Equity Interests"); (x) all right, title and
        interest of each Pledgor in and to all present and future payments,
        proceeds, dividends, distributions, instruments, compensation, property,

        Pledged Equity Interests of such Pledgor, and all monies due or to
        become due and payable to such Pledgor in connection with or related to
        the Pledged Equity Interests of such Pledgor or otherwise paid, issued
        or distributed from time to time in respect of or in exchange therefor,
        and any certificate, instrument or other document evidencing or
        representing the same (including, without limitation, all proceeds of
        dissolution or liquidation), (y) all instruments of indebtedness
        (whether now existing or hereafter arising) by any of the issuers listed
        in Schedule I hereto which name any Pledgor as payee thereunder
        (collectively, the "Pledged Notes"); and (z) all proceeds of every kind
        and nature, including proceeds of proceeds, of any and all of the
        foregoing (including, without limitation, proceeds which constitute
        property of the type described above) and to the extent not otherwise
        included, all money and cash;

        provided, that the Pledged Collateral of a Pledgor shall not include
more than 65% of the issued and outstanding shares of the voting Capital Stock
of any Excluded Foreign Subsidiary; provided, further, that immediately upon the
amendment of the Code to allow the pledge of a greater percentage of the voting
Capital Stock or other voting interests in a Foreign Subsidiary without adverse
tax consequences, the Pledged Collateral shall include, and the security
interest granted by such Pledgor shall attach to, such greater percentage of
Capital Stock or other equity interests of each Foreign Subsidiary provided,
further, that the Pledgors shall use their commercially reasonable efforts to
obtain the necessary consents to the pledge of 65% of the shares of PrettNoma
GmbH hereunder, and upon the receipt thereof, shall take all necessary steps to
pledge such shares hereunder. The Pledgors and the Administrative Agent agree
that nothing in the Loan Agreement, the Security Agreement or this Pledge
Agreement is intended to result in the direct or indirect pledge of (x) the
assets of a "controlled foreign corporation" (as defined in the Code) or (y)
more than 65% of the total combined voting power of all classes of stock
entitled to vote of a "controlled foreign corporation."

        (b)     The shares of stock, certificates, instruments or other
documents evidencing or representing the foregoing shall be collectively
referred to herein as the "Pledged Securities".

        3.      Delivery of Certificates, Instruments, Etc.; Pledgors Remain
Liable.

        (a)     Each Pledgor shall deliver to the Administrative Agent or its
bailee:

                (i)     all original shares of stock, certificates, instruments
        having a value in excess of $1,000,000 and other documents evidencing or
        representing the initial Pledged Collateral of such Pledgor concurrently
        with the execution and delivery of this Pledge Agreement, and

                (ii)    the original shares of stock, certificates, instruments
        or other documents evidencing or representing all other Pledged
        Collateral of such Pledgor (except for such Pledged Collateral which
        this Pledge Agreement specifically permits such Pledgor to retain)
        within one Business Day after such Pledgor's receipt thereof. Each
        delivery of Pledged Collateral shall be accompanied by a schedule
        showing a description of the collateral theretofore and then being
        pledged hereunder, which schedule shall be attached









<PAGE>


                                                                               3

        hereto as Schedule I and made a part hereof. Each schedule so delivered
        shall supersede any prior schedules so delivered.

        (b)     All Pledged Collateral which are certificated securities within
the meaning of the UCC shall be in bearer form or, if in registered form, shall
be issued in the name of the Administrative Agent or its bailee or endorsed to
the Administrative Agent or accompanied by undated blank stock or equity
interest powers, note power, endorsement or other necessary instruments of
transfer, registration or assignment, duly executed in blank and in form and
substance reasonably satisfactory to the Administrative Agent.

        (c)     If any Pledged Securities are "uncertificated securities" within
the meaning of the UCC or are otherwise not evidenced by any certificate or
instrument, the applicable Pledgor will promptly notify the Administrative Agent
thereof and will promptly take and cause to be taken, and will (if the issuer of
such uncertificated securities is a person other than a subsidiary of a Pledgor)
cause the issuer to take, all actions required under Articles 8 and 9 of the UCC
and any other applicable law, to enable the Administrative Agent, subject to the
Intercreditor Agreement, to acquire "control" (within the meaning of such term
under Section 8-106 (or its successor provision) of the UCC) of such
uncertificated securities and as may be otherwise reasonably deemed necessary or
appropriate by the Administrative Agent to perfect the security interest of the
Administrative Agent therein. If any Pledged Securities represent interests in a
limited partnership or a limited liability company, the applicable Pledgor will
cause the issuer thereof not to take any action that would cause such Pledged
Securities to become a "security" within the meaning of Section 8-102 of the UCC
unless such Pledgor complies with the provisions of paragraph 3(a) above (in the
case of certificated securities) or this paragraph 3(c) (in the case of
"uncertificated securities"), as the case may be. Pursuant to any applicable
law, each Pledgor authorizes the Administrative Agent to file or record
financing statements and other filing or recording documents or instruments with
respect to the Collateral without the signature of such Pledgor in such form and
in such offices as the Administrative Agent determines appropriate to perfect
the security interests of the Administrative Agent under this Pledge Agreement.

        (d)     Anything herein to the contrary notwithstanding, (i) each
Pledgor shall remain liable under the contracts and agreements included in the
Pledged Collateral of such Pledgor to the extent set forth therein to perform
all of its duties and obligations thereunder to the same extent as if this
Pledge Agreement had not been executed, (ii) the exercise by the Administrative
Agent of any of the rights hereunder shall not release any Pledgor from any of
its duties or obligations under the contracts and agreements included in the
Pledged Collateral of such Pledgor, except to the extent that such duties and
obligations may have been terminated by reason of a sale, transfer or other
disposition of such Pledged Collateral as provided in paragraph 11 hereof or as
otherwise expressly permitted under the Loan Agreement, and (iii) neither the
Administrative Agent nor any other Secured Party shall have any obligation or
liability under the contracts and agreements included in the Pledged Collateral
by reason of this Pledge Agreement, nor shall the Administrative Agent or any
Secured Party be obligated to perform any of the obligations or duties of any
Pledgor thereunder or to take any action to collect or enforce any claim for
payment assigned hereunder.

        4.      Registration. At any time and from time to time for so long as
an Event of Default is continuing, subject to the Intercreditor Agreement, the
Administrative Agent may cause all or any of the Pledged Securities of a Pledgor
to be transferred to or registered in the Administrative Agent's name or the
name of its nominee or nominees.

        5.      Representations, Warranties and Covenants of the Pledgor. Each
Pledgor hereby represents, warrants and covenants that:

        (a)     Pledged Collateral. Set forth on Schedule I hereto is a complete
and accurate list and description of all of the Pledged Collateral in which such
Pledgor has granted a security interest hereunder in favor of the Administrative
Agent and such Pledgor is the sole holder of record and the sole beneficial
owner of such Pledged Collateral free and clear of any and all Liens or options
in favor of, or any claims of, any other Person, except the Liens securing the
Exit Facility and the Liens created by this Pledge Agreement.

        (b)     Chief Executive Office; Records; Etc. The address of the chief
executive office of such Pledgor, the state organization identification number
of such Pledgor (if the state of incorporation or organization provides such
organization number) and principal place of business of such Pledgor, and the
location of the books and records relating to the Pledged Collateral of such
Pledgor, are set forth below its signature hereto, and such Pledgor will not
change said address or location, or merge or consolidate with any Person or
change its name, without the prior consent of the Administrative Agent, which
shall not be unreasonably withheld.

        (c)     Percentage of Outstanding Equity. The Pledged Securities in
which such Pledgor has granted a security interest hereunder to the
Administrative Agent constitute, and until the indefeasible payment and
performance in full in cash of the Secured Obligations will continue to
constitute, the percentage of the outstanding equity of each such issuer as
indicated on Schedule I hereto.

        (d)     All of Such Pledgor's Interests. The Pledged Securities of such
Pledgor constitutes, and until the indefeasible payment and performance in full
in cash of the Secured Obligations will continue to constitute, all the issued
and outstanding shares of all classes of the equity interests held by such
Pledgor in any of the issuers listed on Schedule I hereto or, in the case of
voting Capital Stock held by such Pledgor in a Excluded Foreign Subsidiary, 65%
of such issued and outstanding shares.

        (e)     Due Authorization, Etc., of Stock. The Pledged Securities listed
on Schedule I next to the name of such Pledgor have been duly authorized and
validly issued and are fully paid and non-assessable and are not subject to any
options to purchase or similar rights of any Person.

        (f)     Pledged Notes. Each of the Pledged Notes constitutes the legal,
valid and binding obligation of the obligor with respect thereto, enforceable in
accordance with its terms, subject to the effects of bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and other similar laws
relating to or affecting creditors' rights generally, general equitable
principles (whether considered in a proceeding in equity or at law) and an
implied covenant of good faith and fair dealing.

        (g)     Required Consents. Except as may be required in connection with
any disposition of any portion of the Pledged Securities of such Pledgor by laws
affecting the offering and sale of securities generally, no consent of any
Person (including, without limitation, the shareholders or other equityholders,
partners or creditors of such Pledgor) and no license, permit, approval or
authorization of, exemption by, notice or report to, or registration, filing
(other than the filing of financing statements under the UCC in order to perfect
a security interest in that portion of the Pledged Collateral of such Pledgor
constituting general intangibles) or declaration with any governmental
instrumentality is required in connection with (i) the execution, delivery or
performance by or enforceability or validity of this Pledge Agreement, (ii) the
perfection or maintenance of the security interest created hereby (including the
priority nature of such security interest described in clause (h) below) or
(iii) the exercise by the Administrative Agent of the voting or other rights
provided for in this Pledge Agreement. By its signature to this Pledge
Agreement, such Pledgor consents to the other Pledgors' pledge and assignment

                                                                               5

of their respective interests in the Pledged Collateral and agrees,
notwithstanding anything contained in any agreement or document with respect to
any of the Pledged Collateral, that there shall be no restriction on the
Administrative Agent as to any transfer of any Pledged Collateral of such
Pledgor as a result of the exercise of any of its rights hereunder (and such
Pledgor hereby consents to any such transfer by the Administrative Agent). Such
Pledgor further agrees that it will not, directly or indirectly, amend, modify
or waive any provisions contained in any agreement or document with respect to
any Pledged Collateral of such Pledgor which would have the effect of
restricting the ability of the Administrative Agent to transfer such Pledged
Collateral as a result of the exercise of any of the Administrative Agent's
rights hereunder.

        (h)     Nature of Security Interest. Upon the delivery of the Pledged
Collateral of such Pledgor to the Administrative Agent or its bailee (in the
case of capital stock, instruments or certificated limited liability company or
limited partnership interests) or the filing of appropriate UCC financing
statements, the pledge of the Pledged Collateral of such Pledgor pursuant to
this Pledge Agreement creates a valid and perfected second priority, at any time
when an Exit Facility remains outstanding and in effect (or first priority at
any time when no Exit Facility remains outstanding or in effect), security
interest in the Pledged Collateral of such Pledgor in favor of the
Administrative Agent, securing the prompt and complete payment, performance and
observance of the Secured Obligations.

        (i)     Further Assurances. Such Pledgor will, at its sole cost and
expense, perform all acts and execute all documents reasonably requested by the
Administrative Agent from time to time to evidence, perfect, maintain or enforce
the Administrative Agent's security interest granted herein or otherwise in
furtherance of the provisions of this Pledge Agreement. Such Pledgor authorizes
the Administrative Agent to execute any documents in the Pledgor's name and
authorizes the Administrative Agent to file such financing statements in any
appropriate filing office to evidence, perfect, maintain or enforce the
Administrative Agent's security interest granted herein or otherwise in
furtherance of the provisions of this Pledge Agreement.

        6.      Voting Rights and Certain Payments Prior to Default. So long as
no Event of Default shall have occurred and be continuing, each Pledgor shall be
entitled:

        (a)     to exercise, in a manner not inconsistent with the terms hereof
or of the other Loan Documents or the Secured Obligations, all voting and
corporate or other organizational rights with respect to the Pledged Securities
of such Pledgor, and for that purpose the Administrative Agent shall (if any
Pledged Securities of such Pledgor shall be registered in the name of the
Administrative Agent or its nominee) execute or cause to be executed from time
to time, at the expense of such Pledgor, such proxies or other instruments in
favor of such Pledgor or its nominee, in such form and for such purposes as
shall be reasonably required by such Pledgor and shall be specified in a written
request therefor, to enable it to exercise such voting or corporate or other
organizational right with respect to such Pledged Securities; provided, however,
that no vote shall be cast or corporate or other organizational right exercised
or other action taken which, in the Administrative Agent's reasonable judgment,
would impair the Pledged Collateral or which would be inconsistent with or
result in any violation of any provision of the Loan Agreement, this Pledge
Agreement or any other Loan Document, and

        (b)     except as otherwise provided in paragraphs 7 and 8 hereof, to
receive and retain for its own account any and all payments, proceeds, cash
dividends, distributions, monies, compensation, property, assets, instruments or
rights, to the extent such are permitted pursuant to the terms of the Loan
Agreement, other than (i) stock or liquidating dividends or distributions or
returns of capital or (ii) extraordinary dividends or distributions and
dividends or distributions or other amounts payable under or in connection with
any recapitalization, restructuring or other non-ordinary course event (the
dividends,

                                                                               6

distributions and amounts in this clause (ii) being "Extraordinary Payments"),
paid, issued or distributed from time to time in respect of the Pledged
Collateral of such Pledgor.

        7.      Extraordinary Payments and Distributions. (a) In case, upon the
dissolution or liquidation (in whole or in part) of any issuer of any Pledged
Collateral, any sum shall be paid or payable as a liquidating dividend or
distribution or return of capital or otherwise upon or with respect to any of
the Pledged Securities of a Pledgor or, in the event any other Extraordinary
Payment is paid or payable, then and in any such event, such sum, subject to the
Intercreditor Agreement, shall be paid over to the Administrative Agent
promptly, and in any event within one (1) Business Day after receipt thereof, to
be held by the Administrative Agent as additional collateral hereunder.

        (b)     In case any stock dividend or distribution payable in additional
Pledged Collateral shall be declared with respect to any of the Pledged
Collateral, or any shares of stock or fractions thereof or other equity
interests shall be issued pursuant to any stock split or other transaction
involving any of the Pledged Collateral, or any distribution of capital shall be
made on any of the Pledged Collateral, or any shares, partnership interests,
obligations or other property shall be distributed upon or with respect to any
of the Pledged Collateral, in each case pursuant to a recapitalization or
reclassification of the capital of the issuer thereof, or pursuant to the
dissolution, liquidation (in whole or in part), bankruptcy or reorganization of
such issuer, or to the merger or consolidation of such issuer with or into
another entity, the shares, obligations or other property so distributed shall,
subject to the Intercreditor Agreement, be delivered to the Administrative Agent
promptly, and in any event within one (1) Business Day after receipt thereof, to
be held by the Administrative Agent as additional collateral hereunder subject
to the terms of this Pledge Agreement, and all of the same shall constitute
Pledged Collateral for all purposes hereof.

        8.      Voting Rights and Certain Payments After an Event of Default.
(a) Upon the occurrence and for so long as an Event of Default is continuing,
all rights of any Pledgor to exercise or refrain from exercising the voting,
managerial and other consensual rights which it would otherwise be entitled to
exercise pursuant to paragraph 6(a) hereof and to receive the payments,
proceeds, dividends, distributions, monies, compensation, property, assets,
instruments or rights which it would otherwise be authorized to receive and
retain pursuant to paragraph 6(b) shall cease, and thereupon, subject to the
Intercreditor Agreement, the Administrative Agent shall be entitled to (i)
exercise (x) all voting, corporate and other rights, powers and privileges with
respect to the Pledged Securities and the other Pledged Collateral of such
Pledgor at any meeting of shareholders of the relevant issuer or issuers or
otherwise and (y) any and all rights of conversion, exchange and subscription
and any other rights, privileges or options pertaining to such Pledged
Collateral as if it were the absolute owner thereof (including, without
limitation, the right to exchange at its discretion any and all of the Pledged
Collateral upon the merger, consolidation, reorganization, recapitalization or
other fundamental change in the corporate or other organizational structure of
any issuer, or upon the exercise by any Pledgor or the Administrative Agent of
any right, privilege or option pertaining to such Pledged Collateral, and in
connection therewith, the right to deposit and deliver any and all of the
Pledged Collateral with any committee, depositary, transfer Administrative
Agent, registrar or other designated agency upon such terms and conditions as
the Administrative Agent may determine), and (ii) to receive and retain, as
additional collateral hereunder, any and all payments, proceeds, cash dividends,
distributions, monies, compensation, property, assets, instruments or rights at
any time declared or paid upon or in respect of any of the Pledged Collateral of
such Pledgor and make application thereof to the Secured Obligations in such
order as the Administrative Agent may determine, all without liability except to
account for property actually received by it, but the Administrative Agent shall
have no duty to any Pledgor to exercise any such right, privilege or option and
shall not be responsible for any failure to do so or delay in so doing.. The
failure on the part of Administrative Agent to give any notice to a Pledgor
prior to the exercise of any voting power or other









<PAGE>


                                                                               7

rights, powers or privileges with respect to the Pledged Collateral of such
Pledgor shall not affect the Administrative Agent's rights under this paragraph
8.

        (b)     All payments, proceeds, cash dividends, distributions, monies,
property, assets, instruments or rights which are received by a Pledgor contrary
to the provisions of subparagraph (a) above shall be received and held in trust
for the benefit of the Administrative Agent, shall be segregated by such Pledgor
from other funds of such Pledgor and shall be forthwith paid over to the
Administrative Agent as Pledged Collateral in the same form as so received (with
any necessary endorsement).

        (c)     Each Pledgor hereby authorizes and instructs each issuer of any
Pledged Collateral pledged by such Pledgor hereunder to (i) comply with any
instruction received by it from the Administrative Agent in writing that (x)
states that an Event of Default has occurred and is continuing and (y) is
otherwise in accordance with the terms of this Pledge Agreement, without any
other or further instructions from such Pledgor, and each Pledgor agrees that
each issuer shall be fully protected in so complying, and (ii) unless otherwise
expressly permitted hereby, pay any dividends or other payments with respect to
the Pledged Collateral directly to the Administrative Agent.

        9.      Application of Cash Collateral. (a) Subject to paragraph 6(b)
hereof, any payments made in respect of the Pledged Notes during the continuance
of an Event of Default shall be and become part of the Pledged Collateral, and,
if received by any Pledgor, shall not be commingled by such Pledgor with any of
its other funds or property but shall be held separate and apart therefrom,
shall be held in trust for the benefit of the Administrative Agent and the
Secured Parties and shall be forthwith delivered to the Administrative Agent in
the same form as so received.

        (b)     Any cash received and retained by the Administrative Agent as
additional collateral hereunder pursuant to the foregoing provisions may, at any
time and from time to time, be applied by the Administrative Agent to the
payment of the Secured Obligations as provided for in the Loan Agreement (or if
not so provided for, as the Administrative Agent shall determine in its sole
discretion).

        10.     Expenses. The Pledgors will upon demand, jointly and severally,
pay the Administrative Agent or any other Secured Party for any and all
reasonable out-of-pocket costs, sums, and expenses which the Administrative
Agent or such Secured Party may pay or incur pursuant to the provisions of this
Pledge Agreement or in enforcing the Secured Obligations, the Pledged Collateral
or the security interest granted hereunder, including, but not limited to, all
filing or recording fees, court costs, collection charges, travel expenses,
computer fees, telephone fees, duplicating fees and reasonable attorneys' fees
and expenses. Such expenses shall include, without limitation, any such costs
paid or incurred by the Administrative Agent or any other Secured Party in
connection with any waivers, amendments, modifications, extensions, renewals or
renegotiations. All of the foregoing, together with interest thereon at the rate
provided in the Loan Agreement, shall be part of the Secured Obligations and be
payable on demand.

        11.     Remedies. (a) Upon the occurrence and for so long as an Event of
Default is continuing, the Administrative Agent may exercise in respect of any
of the Pledged Collateral, in addition to other rights and remedies provided for
herein or otherwise available to it, all the rights and remedies of a secured
party on default under the UCC in effect in the State of New York at that time
(whether or not the UCC is applicable to the affected Pledged Collateral) and
may also, without obligation to resort to other security, at any time and from
time to time sell, resell, assign and deliver, in its sole discretion, all or
any of the Pledged Collateral, in one or more parcels at the same or different
times, and all right, title and interest, claim and demand therein and right of
redemption thereof, on any securities exchange on which any Pledged Collateral
may be listed, or at public or private sale, for cash, upon credit or for future

delivery, and in connection therewith the Administrative Agent may grant
options, each Pledgor hereby waiving and releasing any and all equity and right
of redemption.

        (b)     If any of the Pledged Collateral is sold by the Administrative
Agent pursuant to paragraph 11(a) above upon credit or for future delivery, the
Administrative Agent shall not be liable for the failure of the purchaser to
purchase or pay for the same and, in the event of any such failure, the
Administrative Agent may resell such Pledged Collateral. In no event shall a
Pledgor be credited with any part of the proceeds of sale of any Pledged
Collateral of such Pledgor until cash payment thereof has actually been received
by the Administrative Agent.

        (c)     In connection with any sale of the Pledged Collateral pursuant
to paragraph 11(a) above, the Administrative Agent or any other Secured Party
may purchase any Pledged Collateral at any public sale and, if any Pledged
Collateral is of a type customarily sold in a recognized market or is of the
type which is the subject of widely distributed standard price quotations, the
Administrative Agent or any other Secured Party may purchase such Pledged
Collateral at a private sale, free from any right of redemption, which is hereby
waived and released to the extent permitted by applicable law, and in each case
may make payment therefor by any means, including, without limitation, by
release or discharge of Secured Obligations in lieu of cash payment.

        (d)     The Administrative Agent may apply the cash proceeds actually
received from any sale or other disposition of any of the Pledged Collateral of
a Pledgor pursuant to paragraph 11(a) above to the payment of the Secured
Obligations as provided in the Loan Agreement (or if not so provided for, as the
Administrative Agent shall determine in its sole discretion). The Pledgors,
jointly and severally, shall remain liable for any deficiency with respect to
the Secured Obligations, which shall bear interest at the interest rate
applicable to such Secured Obligations and be payable at such time, in each case
as provided in the Loan Agreement. The right of a Pledgor to receive any
surplus, if any, shall be subject to any duty of the Administrative Agent
imposed by law to the holder of any subordinate security interest in the Pledged
Collateral of such Pledgor known to the Administrative Agent. Nothing contained
herein shall be construed as requiring the Administrative Agent to take any such
action at any time.

        (e)     If the Administrative Agent shall determine to exercise its
right to sell any or all of the Pledged Collateral pursuant to this paragraph,
and if in the opinion of the Administrative Agent it is necessary or advisable
to have the Pledged Collateral, or that portion thereof to be sold, registered
under the provisions of the Securities Act, the relevant Pledgor will cause the
issuer thereof to (i) execute and deliver, and cause the directors and officers
of such issuer to execute and deliver, all such instruments and documents, and
do or cause to be done all such other acts as may be, in the opinion of the
Administrative Agent, necessary or advisable to register the Pledged Collateral,
or that portion thereof to be sold, under the provisions of the Securities Act,
(ii) use its best efforts to cause the registration statement relating thereto
to become effective and to remain effective for a period of one year from the
date of the first public offering of the Pledged Collateral, or that portion
thereof to be sold, and (iii) make all amendments thereto and/or to the related
prospectus which, in the opinion of the Administrative Agent, are necessary or
advisable, all in conformity with the requirements of the Securities Act of 1933
(the "Securities Act") and the rules and regulations of the Securities and
Exchange Commission applicable thereto. Each Pledgor agrees to cause such issuer
to comply with the provisions of the securities or Blue Sky laws of any and all
jurisdictions which the Administrative Agent shall designate and to make
available to its security holders, as soon as practicable, an earnings statement
(which need not be audited) which will satisfy the provisions of Section 11(a)
of the Securities Act.

        (f)     Each Pledgor recognizes that the Administrative Agent may be
unable to effect a public sale pursuant to paragraph 11(a) above of all or part
of the Pledged Collateral of such Pledgor

                                                                               9

consisting of securities by reason of certain prohibitions contained in the
Securities Act, or in applicable Blue Sky or other state securities laws or
otherwise, as now or hereafter in effect, but may be compelled to resort to one
or more private sales to a restricted group of purchasers who will be obliged to
agree, among other things, to acquire such securities for their own account, for
investment and not with a view to the distribution or resale thereof. Each
Pledgor acknowledges and agrees that any such Pledged Collateral sold at any
such private sale may be sold at a price and upon other terms less favorable to
the seller than if sold at public sale and that each such private sale shall be
deemed to have been made in a commercially reasonable manner. The Administrative
Agent shall have no obligation to delay sale of any such securities for the
period of time necessary to permit the issuer of such securities, even if such
issuer would agree, to register such securities for public sale under the
Securities Act or under applicable Blue Sky or other state securities laws. Each
Pledgor agrees that private sales made under the foregoing circumstances shall
be deemed to have been made in a commercially reasonable manner.

        (g)     Each Pledgor agrees to use its best efforts to do or cause to be
done all such other acts as may be necessary to make such sale or sales of all
or any portion of the Pledged Collateral pursuant to Section 11(e) and Section
11(f) valid and binding and in compliance with any and all other applicable
Requirements of Law. Each Pledgor further agrees that a breach of any of the
covenants contained in Section 11(e), Section 11(f) and this Section will cause
irreparable injury to the Administrative Agent and the Lenders, that the
Administrative Agent and the Lenders have no adequate remedy at law in respect
of such breach and, as a consequence, that each and every covenant contained in
Section 11(e), Section 11(f) and this Section shall be specifically enforceable
against such Pledgor, and such Pledgor hereby waives and agrees not to assert
any defenses against an action for specific performance of such covenants except
for a defense that no Event of Default has occurred under the Loan Agreement.

        (h)     No demand, advertisement or notice, all of which are hereby
expressly waived, shall be required in connection with any sale or other
disposition of any part of the Pledged Collateral pursuant to paragraph 11(a)
above which threatens to decline speedily in value or which is of a type
customarily sold on a recognized market; otherwise the Administrative Agent
shall give the applicable Pledgor at least ten days' prior notice of the time
and place of any public sale and of the time after which any private sale or
other disposition is to be made, which notice each Pledgor agrees is reasonable,
all other demands, advertisements and notices being hereby waived.

        (i)     The Administrative Agent shall not be obligated to make any sale
of Pledged Collateral pursuant to paragraph 11(a) above if it shall determine
not to do so, regardless of the fact that notice of sale may have been given.
The Administrative Agent may, without notice or publication, adjourn any public
or private sale or cause the same to be adjourned from time to time by
announcement at the time and place fixed for sale, and such sale may, without
further notice, be made at the time and place to which the same was so
adjourned.

        (j)     The remedies provided herein in favor of the Administrative
Agent shall not be deemed exclusive, but shall be cumulative, and shall be in
addition to all other remedies in favor of the Administrative Agent existing at
law or in equity.

        12.     Administrative Agent Appointed Attorney-in-Fact. (a) To
effectuate the terms and provisions hereof, each Pledgor hereby appoints the
Administrative Agent as its attorney-in-fact for the purpose, from and after the
occurrence and for so long as an Event of Default is continuing, of carrying out
the provisions of this Pledge Agreement and taking any action and executing any
instrument which the Administrative Agent may deem necessary or advisable to
accomplish the purposes hereof. Without limiting the generality of the
foregoing, the Administrative Agent shall, from and after the occurrence and for
so long as an Event of Default is continuing, have the right and power to:

                                                                              10

                (i)     receive, endorse and collect all checks and other orders
        for the payment of money made payable to a Pledgor representing any
        interest or dividend or other distribution or amount payable in respect
        of the Pledged Collateral of such Pledgor or any part thereof and to
        give full discharge for the same, and

                (ii)    execute endorsements, assignments or other instruments
        of conveyance or transfer with respect to all or any of the Pledged
        Collateral and to exercise all rights and privileges of (or on behalf
        of) the owner of any Pledged Collateral, including, without limitation,
        all voting rights with respect to the Pledged Securities.

        (b)     All acts done under the foregoing authorization are hereby
ratified and approved by each Pledgor and neither the Administrative Agent, any
other Secured Party nor any designee or agent thereof shall be liable for any
acts of commission or omission, for any error of judgment or for any mistake of
fact or law except for their willful misconduct or gross negligence.

        (c)     This power of attorney, being coupled with an interest, is
irrevocable until the indefeasible payment and performance in full in cash of
the Secured Obligations and the expiration or termination of the Commitments.

        13.     Administrative Agent's Duties; Reasonable Care. (a) The
Administrative Agent shall have the duty to exercise reasonable care in the
custody and preservation of any Pledged Collateral in its possession, which duty
shall be fully satisfied if the Administrative Agent maintains safe custody of
such Pledged Collateral and, with respect to any calls, conversions, exchanges,
redemptions, offers, tenders or similar matters relating to any such Pledged
Collateral (herein called "events"),

                (i)     the Administrative Agent exercises reasonable care to
        ascertain the occurrence and to give reasonable notice to the applicable
        Pledgor of any events applicable to any Pledged Securities of such
        Pledgor which are registered and held in the name of the Administrative
        Agent or its nominee,

                (ii)    the Administrative Agent gives the applicable Pledgor
        reasonable notice of the occurrence of any events, of which the
        Administrative Agent has received actual knowledge, as to any securities
        which are in bearer form or are not registered and held in the name of
        the Administrative Agent or its nominee (such Pledgor agreeing to give
        the Administrative Agent reasonable notice of the occurrence of any
        events applicable to any securities in the possession of the
        Administrative Agent of which such Pledgor has received knowledge), and

                (iii)   in the exercise of its sole discretion (x) the
        Administrative Agent endeavors to take such action with respect to any
        of the events as the applicable Pledgor may reasonably and specifically
        request in writing in sufficient time for such action to be evaluated
        and taken or (y) if the Administrative Agent determines that the action
        requested may adversely affect the value of the Pledged Collateral of
        such Pledgor as collateral, the collection of the Secured Obligations,
        or otherwise prejudice the interests of the Administrative Agent or any
        other Secured Party, the Administrative Agent gives notice to such
        Pledgor that any such requested action will not be taken and if the
        Administrative Agent makes such determination or if such Pledgor fails
        to make such timely request, the Administrative Agent takes such other
        action as it deems advisable in the circumstances.









<PAGE>


                                                                              11

        (b)     Except as hereinabove specifically set forth, the Administrative
Agent shall have no further obligation to ascertain the occurrence of, or to
notify any Pledgor with respect to, any events and shall not be deemed to assume
any such further obligation as a result of the establishment by the
Administrative Agent of any internal procedures with respect to any securities
in its possession, nor shall the Administrative Agent be deemed to assume any
other responsibility for, or obligation or duty with respect to, any Pledged
Collateral, or its use, of any nature or kind, or any matter or proceedings
arising out of or relating thereto, including, without limitation, any
obligation or duty to take any action to collect, preserve or protect its or the
applicable Pledgor's rights in the Pledged Collateral of such Pledgor or against
any prior parties thereto, but the same shall be at such Pledgor's sole risk and
responsibility at all times.

        (c)     Each Pledgor hereby releases the Administrative Agent and the
other Secured Parties from any claims, causes of action and demands at any time
arising out of or with respect to this Pledge Agreement, the Pledged Collateral
of such Pledgor and/or any actions taken or omitted to be taken by the
Administrative Agent or the other Secured Parties with respect thereto (except
such claims, causes of action and demands arising from the gross negligence or
willful misconduct of the Administrative Agent or the other Secured Parties) and
each Pledgor hereby agrees to hold the Administrative Agent and the other
Secured Parties harmless from and with respect to any and all such claims,
causes of action and demands (except such claims, causes of action and demands
arising from the gross negligence or willful misconduct of the Administrative
Agent or the other Secured Parties).

        14.     Rights and Remedies Not Waived. The Administrative Agent's prior
recourse to any Pledged Collateral shall not constitute a condition of any
demand, suit or proceeding for payment or collection of the Secured Obligations.
No act, omission or delay by the Administrative Agent or any other Secured Party
shall constitute a waiver of its rights and remedies hereunder or otherwise. No
single or partial waiver by the Administrative Agent of any default hereunder or
right or remedy which it may have shall operate as a waiver of any other
default, right or remedy or of the same default, right or remedy on a future
occasion.

        15.     Administrative Agent May Perform. If any Pledgor fails to
perform any agreement contained herein, the Administrative Agent may itself
perform, or cause performance of, such agreement, and the expenses of the
Administrative Agent incurred in connection therewith shall be payable by the
Pledgors pursuant to the terms of paragraph 10 hereof.

        16.     Setoff; Submission To Jurisdiction; Waivers. Each Pledgor hereby
irrevocably and unconditionally:

                (i)     submits for itself and its property in any legal action
        or proceeding relating to this Security Agreement and the other Loan
        Documents to which it is a party, or for recognition and enforcement of
        any judgment in respect thereof, to the non-exclusive general
        jurisdiction of the courts of the State of New York, the courts of the
        United States of America for the Southern District of New York, and
        appellate courts from any thereof;

                (ii)    consents that any such action or proceeding may be
        brought in such courts and waives any objection that it may now or
        hereafter have to the venue of any such action or proceeding in any such
        court or that such action or proceeding was brought in an inconvenient
        court and agrees not to plead or claim the same;

                (iii)   agrees that service of process in any such action or
        proceeding may be effected by mailing a copy thereof by registered or
        certified mail (or any substantially

                                                                              12

        similar form of mail), postage prepaid, to such Pledgor at its address
        referred to in the Loan Agreement or at such other address of which the
        Administrative Agent shall have been notified pursuant thereto;

                (iv)    agrees that nothing herein shall affect the right to
        effect service of process in any other manner permitted by law or shall
        limit the right to sue in any other jurisdiction;

                (v)     waives, to the maximum extent not prohibited by law, any
        right it may have to claim or recover in any legal action or proceeding
        referred to in this Paragraph any special, exemplary, punitive or
        consequential damages;

                (vi)    waives the right to interpose any setoff, recoupment,
        counterclaim or cross-claim in connection to any such legal action or
        proceeding, irrespective of the nature of such setoff, recoupment,
        counterclaim or cross-claim, unless such setoff, recoupment counterclaim
        or cross-claim could not, by reason of any applicable federal or state
        procedural laws, be interposed, pleaded or alleged in any other action;

                (vii)   agrees that no provision of this Pledge Agreement shall
        limit the right of the Administrative Agent to exercise self-help
        remedies such as setoff or obtaining provisional or ancillary remedies
        from a court of competent jurisdiction before, after, or during the
        pendency of any arbitration or other proceeding. The exercise of a
        remedy does not waive the right of any party to resort to arbitration or
        reference; and

                (viii)  agrees that this Paragraph 16 is a specific and material
        aspect of this Pledge Agreement and acknowledges that the Secured
        Parties would not extend to the borrowers any financial accommodations
        under the Loan Agreement if this Paragraph 16 were not part of this
        Pledge Agreement.

        17.     WAIVER OF JURY TRIAL. EACH PLEDGOR HEREBY IRREVOCABLY AND
UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING
TO THIS PLEDGE AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM
THEREIN.

        18.     Admissibility of Pledge Agreement. Each Pledgor agrees that any
copy of this Pledge Agreement signed by such Pledgor and transmitted by
telecopier for delivery to the Administrative Agent shall be admissible in
evidence as the original itself in any judicial or administrative proceeding,
whether or not the original is in existence.

        19.     Address for Notices. All notices, requests, demands and other
communications provided for hereunder shall be in writing (unless otherwise
expressly provided herein) and mailed, telegraphed, telexed, telecopied, cabled
or delivered, if to a Pledgor, at the address specified below its signature
below and if to the Administrative Agent, at its address specified below its
signature below or, at such other address as shall be designated by any party in
a written notice to the other parties hereto. All notices and communications
given by a telecommunications device shall be capable of creating a written
record of confirmation receipt. All such notices and communications shall be
mailed, telegraphed, telexed, telecopied or cabled or sent by overnight courier
or personal delivery, and shall be effective when received.

        20.     Amendments in Writing. None of the terms or provisions of this
Pledge Agreement may be waived, amended, supplemented or otherwise modified
except in accordance with Section 9.1 of the Loan Agreement.

        21.     Continuing Security Interest; Assignments. This Pledge Agreement
shall create a continuing security interest in the Pledged Collateral and shall
(i) remain in full force and effect until the indefeasible payment and
performance in full in cash of the Secured Obligations, (ii) be binding upon and
inure to the benefit of, and be enforceable by, each Pledgor and its successors
and assigns, and (iii) be binding upon and inure to the benefit of, and be
enforceable by, the Administrative Agent and its successors, transferees and
assigns. Upon the indefeasible payment and performance in full in cash of the
Secured Obligations the security interest granted hereby shall terminate and all
rights to the Pledged Collateral shall revert to the applicable Pledgors. Upon
any such termination, the Administrative Agent will, at Pledgors' expense,
execute and deliver to the Pledgors such documents as the Pledgors shall
reasonably request to evidence such termination and will assign, transfer and
deliver to the Pledgors, without recourse and without representation or
warranty, such of the Pledged Collateral as may then be in possession of the
Administrative Agent.

        22.     Intercreditor Agreement. Notwithstanding anything in this Pledge
Agreement to the contrary, (a) the Lien granted to the Administrative Agent
pursuant to this Pledge Agreement and the exercise of any right or remedy by the
Administrative Agent hereunder are subject to the provisions of the
Intercreditor Agreement and (b) with respect to the delivery of Pledged
Collateral which may be perfected by possession by the secured party with
respect thereto, or which is required pursuant to the terms of this Pledge
Agreement, such delivery shall be deemed to have been complied with so long as
such delivery is made to the Exit Facility Agent and held subject to Section 5.5
of the Intercreditor Agreement. In the event of any conflict between the terms
of the Intercreditor Agreement and this Pledge Agreement, the terms of the
Intercreditor Agreement shall govern.

        23.     Governance of Loan Agreement. The parties hereto agree that to
the extent any provisions herein conflict with the Loan Agreement, the
provisions of the Loan Agreement shall control.

        24.     Counterparts. This Pledge Agreement may be executed by the
parties hereto individually or in any combination, in one or more counterparts,
each of which shall be an original and all of which shall together constitute
one and the same agreement.

        25.     Captions; Separability. The captions of the various sections and
paragraphs of this Pledge Agreement have been inserted only for the purposes of
convenience; such captions are not a part of this Pledge Agreement and shall not
be deemed in any manner to modify, explain, enlarge or restrict any of the
provisions of this Pledge Agreement.

        26.     Security Interest Absolute. All rights of the Administrative
Agent and security interests hereunder, and all of the obligations of each
Pledgor hereunder, shall be absolute and unconditional, irrespective of:

                (i)     any lack of validity or enforceability of any Loan
        Document, any Secured Obligations or any other agreement or instrument
        relating thereto;

                (ii)    any change in the time, manner or place of payment of,
        or in any other term of, all or any of the Secured Obligations, or any
        other amendment or waiver of or any consent to any departure from any
        Loan Document;

                                                                              14

                (iii)   any exchange, release or non-perfection of any other
        collateral, or any release or amendment or waiver of or consent to
        departure from any guaranty, for all or any of the Secured Obligations;
        or

                (iv)    any other circumstance which might otherwise constitute
        a defense available to, or a discharge of, any Pledgor or a third party
        grantor of a security interest or Lien.

        27.     GOVERNING LAW. THIS PLEDGE AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

        28.     Schedules. The Administrative Agent is authorized to annex
hereto any schedules referred to herein.

        29.     Additional Grantors. Each Subsidiary of the Borrower that is
required to become a party to this Agreement pursuant to Section 5.9 of the Loan
Agreement shall become a Pledgor for all purposes of this Pledge Agreement upon
execution and delivery by such Subsidiary of an Assumption Agreement in the form
of Annex 1 hereto.

        30.     Releases. (a) At such time as the Loans and the other Secured
Obligations shall have been paid in full, the Pledged Collateral shall be
released from the liens created hereby, and this Pledge Agreement and all
obligations (other than those expressly stated to survive such termination) of
the Administrative Agent and each Pledgor hereunder shall terminate, all without
delivery of any instrument or performance of any act by any party, and all
rights to the Pledged Collateral shall revert to the Pledgors. At the request
and sole expense of any Pledgor following any such termination, the
Administrative Agent shall deliver to such Pledgor any Pledged Collateral held
by the Administrative Agent hereunder, and execute and deliver to such Pledgor
such documents as such Pledgor shall reasonably request to evidence such
termination.

        (b)     If any of the Pledged Collateral shall be sold, transferred or
otherwise disposed of by any Pledgor in a transaction permitted by the Loan
Agreement, then the Administrative Agent, at the request and sole expense of
such Pledgor, shall execute and deliver to such Pledgor all releases or other
documents reasonably necessary or desirable for the release of the liens created
hereby on such Pledged Collateral. At the request and sole expense of GenTek, a
Pledgor shall be released from its obligations hereunder in the event that all
the Capital Stock of such Pledgor shall be sold, transferred or otherwise
disposed of in a transaction permitted by the Loan Agreement; provided that
GenTek shall have delivered to the Administrative Agent, at least five Business
Days prior to the date of the proposed release, a written request for release
identifying the relevant Pledgor and the terms of the sale or other disposition
in reasonable detail, including the price thereof and any expenses in connection
therewith, together with a certification by GenTek stating that such transaction
is in compliance with the Pledge Agreement and the other Loan Documents.

        31.     Acknowledgment of Receipt. Each Pledgor acknowledges receipt of
a copy of this Pledge Agreement.
