        2.1 Subordination. Notwithstanding the date, manner or order of grant,
attachment or perfection of any Liens granted to the Junior Agent or any of the
Junior Lenders on the Shared Collateral or of any Liens granted to the Senior
Agent or any of the Senior Lenders on the Shared Collateral and notwithstanding
any provision of the UCC, or any applicable law or the Junior Lender Documents
or the Senior Lender Documents or any other circumstance whatsoever, the Junior
Agent, on behalf of itself and the Junior Lenders, hereby agrees that: (a) any
Lien on the Shared Collateral securing all or any portion of the Senior Lender
Claims now or hereafter held by the Senior Agent or any of the Senior Lenders
shall be senior and prior to any Lien on the Shared Collateral securing all or
any portion of the Junior Lender Claims; and (b) any Lien on the Shared
Collateral now or hereafter held by the Junior Agent or any of the Junior
Lenders regardless of how acquired, whether by grant, statute, operation of law,
subrogation or otherwise, shall be junior and subordinate in all respects to all

<PAGE>

portion of the Junior Lender Claims for all purposes, whether or not any such
Liens securing all or any portion of the Senior Lender Claims are subordinated
to any Lien securing any other obligation of any GenTek Obligor.

        2.2 Prohibition on Contesting Liens. Each of the Junior Agent, for
itself and on behalf of each Junior Lender, and the Senior Agent, for itself and
on behalf of each Senior Lender, agrees that it shall not (and hereby waives any
right to) contest or support any other Person in contesting, in any proceeding
(including, without limitation, any Insolvency or Liquidation Proceeding), the
priority of each Lien provided for herein or the validity or enforceability of a
Lien held by the Senior Agent or any of the Senior Lenders in any of the Senior
Lender Collateral or by the Junior Agent or any of the Junior Lenders in any of
the Shared Collateral, respectively. Notwithstanding anything herein to the
contrary, in the event it is determined by a final, non-appealable order of a
court of competent jurisdiction (in any action or proceeding in which neither
the Junior Agent nor any of the Junior Lenders have violated the terms of this
Section 2.2) that a Lien in favor of the Senior Agent or the Senior Lenders on
any portion of the Shared Collateral shall be equitably subordinated by virtue
of the misconduct of the Senior Agent or the Senior Lender to the claims of
creditors of the applicable GenTek Obligor, then the Junior Lenders shall not be
required to subordinate their Lien on such portion of the Shared Collateral, but
only if it is or has been determined that the Lien of the Junior Lenders in such
Shared Collateral is valid and enforceable.

        2.3 No New Liens. The parties hereto agree that prior to the Discharge
of Senior Lender Claims (a) if the Junior Agent or any Junior Lender shall hold
any Lien on any assets of GenTek or any Subsidiary of GenTek securing any Junior
Lender Claims that are not also subject to the first-priority Lien of the Senior
Agent or have not been consented to by the Necessary Lenders, under the Senior
Lender Documents, the Junior Agent, upon demand by the Senior Agent, will either
release (or cause the release of) such Lien or assign (or cause to be assigned)
a first-priority Lien to the Senior Agent as security for the Senior Lender
Claims, (b) each GenTek Obligor hereby agrees not to grant any Lien on any of
its assets, or permit any Subsidiary thereof to grant a Lien on any of its
assets, in favor of the Junior Agent or any Junior Lender unless it, or such
Subsidiary, has granted a similar Lien on such assets in favor of the Senior
Agent or such Lien has been consented to by the Necessary Lenders, and (c) each
GenTek Obligor hereby agrees that it shall not permit any Foreign Subsidiary or
other Non-Loan Party (including, without limitation, Noma) to grant any Lien on
any of its assets and the Junior Agent on behalf of itself and the Junior
Lenders agree that neither it nor they shall accept any such grant of a Lien
(and if any such grant is nevertheless made, the Junior Agent on behalf of
itself and the Junior Lenders hereby releases such Lien).

        Section 3. Enforcement.

        3.1 Exercise of Remedies.

        (a) Prior to the Discharge of Senior Lender Claims, whether or not any
Insolvency or Liquidation Proceeding has been commenced by or against any GenTek
Obligor: (i) the Junior Agent and the Junior Lenders will not exercise or seek
to exercise any rights or remedies (including setoff) with respect to any Shared
Collateral, institute any action or proceeding with respect to any such rights
or remedies, including, without limitation, any action


                                        7









<PAGE>

of foreclosure, contest, protest or object to any foreclosure proceeding or
action brought by the Senior Agent or any Senior Lender, the exercise of any
right under any Blocked Account Agreement, landlord waiver or bailee's waiver or
similar agreement or arrangement to which the Junior Agent or any Junior Lender
is a party, or any other exercise by any such party, of any rights and remedies
relating to the Shared Collateral under the Junior Lender Documents or
otherwise, or object to the forbearance by the Senior Agent or any of the Senior
Lenders from bringing or pursuing any foreclosure proceeding or action or any
other exercise of any rights or remedies relating to the Shared Collateral; and
(ii) the Senior Agent and the Senior Lenders shall have the exclusive right to
enforce rights, exercise remedies (including, without limitation, setoff and the
right to credit bid their debt) and make determinations regarding release,
disposition, or restrictions with respect to the Shared Collateral without any
consultation with or the consent of the Junior Agent or any Junior Lender.

        (b) In exercising rights and remedies with respect to the Shared
Collateral, the Senior Agent and the Senior Lenders may enforce the provisions
of the Senior Lender Documents and exercise remedies thereunder, all in such
order and in such manner as they may determine in the exercise of their sole
discretion. Such exercise and enforcement shall include, without limitation, the
rights of an agent appointed by them to sell or otherwise dispose of Shared
Collateral upon foreclosure, to incur expenses in connection with such sale or
disposition, and to exercise all the rights and remedies of a secured lender
under the Uniform Commercial Code of any applicable jurisdiction and of a
secured creditor under bankruptcy or similar laws of any applicable
jurisdiction.

        (c) The Junior Agent, on behalf of itself and the Junior Lenders, agrees
that, prior to the Discharge of Senior Lender Claims, it will not take or
receive any Shared Collateral or any proceeds of Shared Collateral in connection
with the exercise of any right or remedy (including setoff) with respect to any
Shared Collateral. Without limiting the generality of the foregoing, prior to
the Discharge of Senior Lender Claims, the sole right of the Junior Agent and
the Junior Lenders with respect to the Shared Collateral is to hold a Lien on
the Shared Collateral pursuant to the Junior Lender Documents for the period and
to the extent granted therein and to receive the proceeds thereof, if any, after
the Discharge of Senior Lender Claims.

        (d) The Junior Agent, for itself or on behalf of the Junior Lenders, (i)
agrees that neither it nor any of the Junior Lenders will take any action that
would hinder any exercise of remedies undertaken by the Senior Agent or any
Senior Lender under the Senior Loan Documents, including any sale, lease,
exchange, transfer or other disposition of any Shared Collateral, whether by
foreclosure or otherwise and (ii) hereby waives any and all rights it or any of
the Junior Lenders may have as a junior lien creditor or otherwise to object to
the manner in which the Senior Agent or any of the Senior Lenders seek to
enforce or collect any Senior Lender Claims or any Liens granted in any of the
Senior Lender Collateral (except to the extent any such waiver is not
enforceable under applicable law).

        3.2 Cooperation. The Junior Agent, on behalf of itself and the Junior
Lenders, agrees that, prior to the Discharge of Senior Lender Claims, it will
not commence, or join with any Person (other than the Senior Lenders and the
Senior Agent upon the request thereof) in commencing any enforcement,
collection, execution, levy or foreclosure action or proceeding with respect to
any Lien held by it under any of the Junior Lender Documents or otherwise.

as specified in the Senior Credit Agreement. Following Discharge of Senior
Lender Claims, the Senior Agent shall deliver to the Junior Agent any proceeds
of Shared Collateral held by it in the same form as received, with any necessary
endorsements or as a court of competent jurisdiction may otherwise direct. The

Senior Lender Claims. This authorization is coupled with an interest and is
irrevocable.

Lender in connection with the exercise of any right or remedy (including setoff)

forthwith paid over to the Senior Agent for the benefit of the Senior Lenders in
the same form as received, with any necessary endorsements or as a court of
competent jurisdiction may otherwise direct. The Senior Agent is hereby
authorized to make any such endorsements as agent for the Junior Agent or any

Senior Agent and the Senior Lenders to the extent required under the Senior
Credit Agreement, second, but only following the Discharge of Senior Lender
Claims, to the Junior Agent for the benefit of the Junior Lenders to the extent
required under the applicable Junior Lender Documents, and third (second if
prior to the Discharge of Senior Lender Claims) to the owner of the subject
property or as a court of competent jurisdiction may otherwise direct. If the
Junior Agent or any Junior Lender shall, at any time, receive any proceeds of
any such insurance policy or any such award in contravention of this Agreement,
it shall pay such proceeds over to the Senior Agent in accordance with the terms
of Section 4.2.

        5.3 Amendments to Junior Lender Documents.

        (a) Without the prior written consent of the Senior Agent (with the
consent of the Necessary Lenders), no Junior Lender Document may be amended,
supplemented or otherwise modified or entered into to the extent such amendment,
supplement or modification, or the terms of any new Junior Lender Document,
would be adverse in any material respect to the Senior Lenders or inconsistent
with the terms of any Senior Lender Document or this Agreement.

        (b) In the event the Necessary Lenders enter into any amendment, waiver
or consent in respect of any of the Senior Lender Collateral Documents for the
purpose of adding to, or deleting from, or waiving or consenting to any
departures from any provisions of, any such Senior Lender Collateral Document or
changing in any manner the rights of the Senior Agent, the Senior Lenders or the
GenTek Obligors (or any of them) thereunder, then such amendment, waiver or
consent shall, by this reference, apply automatically to any comparable
provision of the Comparable Junior Lender Collateral Document without the
consent of either the Junior Agent or the Junior Lenders and without any action
by the Junior Agent, any Junior Lender or any GenTek Obligor; provided, however,
(A) that no such amendment, waiver or consent shall have the effect of removing
assets subject to the Lien of the Junior Lender Collateral Documents, except to
the extent that a release of such Lien is permitted by Section 5.1 and (B)
notice of such amendment, waiver or consent shall be given to the Junior Agent.

<PAGE>

        (c) The Junior Agent agrees that each Junior Lender Collateral Document
shall include the following language:

        Notwithstanding anything herein to the contrary, the lien and
        security interest granted to the Junior Agent pursuant to this
        Agreement and the exercise of any right or remedy by the Junior
        Agent hereunder are subject to the provisions of the Intercreditor
        Agreement, dated as of November 10, 2003 (the "Intercreditor
        Agreement") among Bank of America, N.A., as Senior Agent, BNY Asset
        Solutions LLC, as Junior Agent, and GenTek Inc. and the
        subsidiaries of GenTek Inc. party thereto. In the event of any
        conflict between the terms of the Intercreditor Agreement and this
        Agreement, the terms of the Intercreditor Agreement shall govern.

        5.4 Rights As Unsecured Creditors.

        (a) Nothing in this Agreement shall prohibit the receipt by the Junior
Agent or any Junior Lenders of the required payments of principal and interest
so long as (i) such payment by the GenTek Obligors is made in accordance with
the terms of the Senior Credit Agreement (as in effect as of the date hereof)
and (ii) such receipt by the Junior Lenders is not the direct or indirect result
of the exercise by the Junior Agent or any Junior Lender of rights or remedies
as a secured creditor or enforcement of any Lien held by any of them. The Junior
Agent shall not be liable for determining in good faith that a payment received
by it was made in compliance with the terms hereof and shall be under no
obligation to determine if such payment is made in accordance with the terms of
the Senior Credit Agreement; provided nothing herein shall limit the rights of
the Senior Agent or the Senior Lenders against the Junior Lenders in the event
any payment received by the Junior Agent and distributed to the Junior Lenders
was not made in compliance herewith.

        (b) Notwithstanding anything to the contrary in this Agreement, the
Junior Agent and the Junior Lenders may exercise rights and remedies as an
unsecured creditor against the GenTek Obligors in accordance with the terms of
the Junior Lender Documents and applicable law. In the event the Junior Agent or
any Junior Lender becomes a judgment lien creditor in respect of Shared
Collateral as a result of its enforcement of its rights as an unsecured
creditor, such judgment lien shall be subordinated to the Liens securing Senior
Lender Claims on the same basis as the other Liens securing the Junior Lender
Claims are so subordinated to such Senior Lender Claims under this Agreement.
Nothing in this Agreement modifies any rights or remedies the Senior Agent or
any of the Senior Lenders may have with respect to the Senior Lender Collateral.

        5.5 Agent and Bailee for Perfection

        (a) The Senior Agent agrees to hold the Shared Collateral that is in its
possession (or in the possession of its agents) as bailee for the Junior Agent
solely for the purpose of perfecting the security interest granted in such
Shared Collateral pursuant to the Junior Lender Security Agreement or other
applicable agreement, subject to the terms and conditions of this Section 5.5.


                                       11









<PAGE>

        (b) Prior to the Discharge of Senior Lender Claims, the Senior Agent
shall be entitled to deal with the Shared Collateral in its possession or under
its control in accordance with the terms of the Senior Lender Documents and this
Agreement. The rights of the Junior Agent shall at all times be subject to the
terms of this Agreement and to the Senior Agent's rights under the Senior Lender
Documents and this Agreement.

        (c) The Senior Agent shall have no obligation whatsoever to the Junior
Agent or any Junior Lender to assure that the Shared Collateral in its
possession or under its control is genuine or owned by a GenTek Obligor or to
preserve rights or benefits of any Person except as expressly set forth in this
Section 5.5. The duties or responsibilities of the Senior Agent under this
Section 5.5 shall be limited solely to holding the Pledged Collateral as bailee
for the Junior Agent for purposes of perfecting the Junior Lien thereon held by
the Junior Agent.

        (d) The Senior Agent shall not have by reason of this Agreement or any
other document a fiduciary relationship in respect of the Junior Agent or any
Junior Lender. The Junior Agent shall not have by reason of this Agreement or
any other document a fiduciary relationship in respect of the Senior Agent or
any Senior Lender.

        (e) Following the Discharge of Senior Lender Claims, at the expense of
the GenTek Obligors, the Senior Agent shall deliver to the Junior Agent the
Pledged Collateral together with any necessary endorsements (or otherwise allow
the Junior Agent to obtain control of such Pledged Collateral) or as a court of
competent jurisdiction may otherwise direct, and shall take all steps reasonably
requested by the Junior Agent to release its Liens on the Shared Collateral
(subject to the terms of the applicable Senior Lender Collateral Document).

        Section 6. Insolvency or Liquidation Proceedings.

        6.1 Financing Issues. If any GenTek Obligor shall be subject to any
Insolvency or Liquidation Proceeding and the Senior Agent shall desire to permit
the use of cash collateral or to permit the GenTek Obligors (or any of them) to
obtain financing under section 363 or section 364 of the Bankruptcy Code ("DIP
Financing"), then the Junior Agent, on behalf of itself and the Junior Lenders,
agrees that it will raise no objection to such use or DIP Financing and will not
request adequate protection or any other relief in connection therewith (except
to the extent permitted by Section 6.3) and, to the extent any of the Liens
securing any Senior Lender Claims are subordinated or pari passu with such DIP
Financing, the Junior Agent will subordinate its Liens in the Shared Collateral
to such DIP Financing and all Obligations relating thereto on the same basis as
the Liens securing the Junior Lender Claims are subordinated to the other Senior
Lender Claims under this Agreement.

        6.2 Relief from the Automatic Stay. The Junior Agent, on behalf of
itself and the Junior Lenders, agrees that, prior to the Discharge of Senior
Lender Claims, none of them shall seek relief from the automatic stay or any
other stay in any Insolvency or Liquidation Proceeding in respect of the Shared
Collateral, without the prior written consent of the Senior Agent (with the
consent of the Necessary Lenders).


                                       12









<PAGE>

        6.3 Adequate Protection.

        (a) The Junior Agent, on behalf of itself and the Junior Lenders, agrees
that none of them shall contest (or support any other Person contesting) (i) any
request by the Senior Agent or any of the Senior Lenders for adequate protection
or (ii) any objection by the Senior Agent or the Senior Lenders to any motion,
relief, action or proceeding based on the Senior Agent or any of the Senior
Lenders claiming a lack of adequate protection.

        (b) Notwithstanding the foregoing clause (a), in any Insolvency or
Liquidation Proceeding, if the Senior Lenders (or any subset thereof) are
granted adequate protection in the form of additional collateral and the payment
of the reasonable fees and expenses of the Senior Agent's legal and financial
advisors in connection with any DIP Financing or use of its cash collateral
under section 363 or section 364 of the Bankruptcy Code, then the Senior Agent
(on behalf of the Senior Lenders) will raise no objection to the grant of
adequate protection in the form of (i) the payment of the reasonable fees and
expenses of the Junior Agent's legal and financial advisors and (ii) additional
collateral to the Junior Agent, on behalf of itself or any of the Junior
Lenders, which Lien shall be subordinated to the Liens securing the Senior
Lender Claims and such DIP Financing (and all Obligations relating thereto) on
the same basis as the other Liens securing the Junior Lender Claims are so
subordinated to the Senior Lender Claims under this Agreement.

        6.4 No Waiver. Nothing contained herein shall prohibit or in any way
limit the Senior Agent or any Senior Lender from objecting in any Insolvency or
Liquidation Proceeding or otherwise to any action taken by the Junior Agent or
any of the Junior Lenders in contravention of this Agreement, including, without
limitation, the seeking by the Junior Agent or any Junior Lender of adequate
protection or the asserting by the Junior Agent or any Junior Lender of any of
its rights and remedies under the Junior Lender Documents or otherwise in
contravention of this Agreement.

        6.5 Preference Issues. If the Senior Agent or any Senior Lender is
required in any Insolvency or Liquidation Proceeding or otherwise to turn over
or otherwise pay to the estate of any GenTek Obligor any amount (a "Recovery"),
then the Senior Lender Claims shall be reinstated to the extent of such Recovery
and the Senior Agent and/or the relevant Senior Lenders shall be entitled to the
Discharge of Senior Lender Claims with respect to all such recovered amounts. If
this Agreement shall have been terminated prior to such Recovery, this Agreement
shall be reinstated in full force and effect, and such prior termination shall
not diminish, release, discharge, impair or otherwise affect the obligations of
the parties hereto from such date of reinstatement.

        6.6 Certain Junior Lender Rights. Notwithstanding anything in this
Agreement to the contrary, prior to the Discharge of the Senior Lender Claims,
in any Insolvency or Liquidation Proceeding commenced by or against any GenTek
Obligor, the Junior Agent or any Junior Lender may file a claim or statement of
interest with respect to the Junior Lender Claims and shall retain the right to
vote and otherwise act as a party in interest (subject to the limitations set
forth in this Agreement) in such Insolvency or Liquidation Proceeding
(including, without limitation, the right to vote to accept or reject any plan
of reorganization); provided that no such Person shall vote with respect to any
such plan of reorganization which adversely affects


                                       13









<PAGE>

or any Senior Lender, (ii) the relative rights and duties of the holders of the
Senior Lender Claims established in the Senior Lender Documents and this
Agreement with respect to such Liens or (iii) the enforceability of the Senior
Credit Agreement or this Agreement.

        Section 7. Reliance; Waivers; etc.

        7.1 Reliance. The consent by the Senior Lenders to the execution and
delivery of the Junior Lender Documents and the grant to the Junior Agent on
behalf of the Junior Lenders of a Lien on the Shared Collateral and all loans
and other extensions of credit made or deemed made on and after the date hereof
by any of the Senior Lenders to any GenTek Obligor shall be deemed to have been
given and made in reliance upon this Agreement.

        7.2 No Warranties or Liability.

        (a) The Junior Agent, on behalf of itself and the Junior Lenders,
acknowledges and agrees that each of the Senior Agent and the Senior Lenders
have made no express or implied representation or warranty, including, without

Senior Agent and the Senior Lenders will be entitled to manage and supervise
their respective loans and extensions of credit to the GenTek Obligors and any
other subsidiary of GenTek in accordance with law and as they may otherwise, in
their sole discretion, deem appropriate, and the Senior Agent and the Senior
Lenders may manage their loans and extensions of credit without regard to any
rights or interests that the Junior Agent or any of the Junior Lenders have in
the Shared Collateral or otherwise. Neither the Senior Agent nor any Senior
Lender shall have any duty to the Junior Agent or any of the Junior Lenders to
act or refrain from acting in a manner which allows, or results in, the
occurrence or continuance of an event of default or default under any agreements
with any GenTek Obligor (including, without limitation, the Junior Lender
Documents), regardless of any knowledge thereof which they may have or be
charged with.

        (b) The Senior Agent, on behalf of itself and the Senior Lenders,
acknowledges and agrees that each of the Junior Agent and the Junior Lenders
have made no express or implied representation or warranty, including, without
limitation, with respect to the execution, validity, legality, completeness,
collectibility or enforceability of any of the Junior Lender Documents. The
Junior Agent and the Junior Lenders will be entitled to manage and supervise
their respective extensions of credit to GenTek in accordance with law and as

Agent and the Junior Lenders may manage their extensions of credit without
regard to any rights or interests that the Senior Agent or any of the Senior
Lenders have in the Shared Collateral or otherwise, except as otherwise provided
in this Agreement. Except as provided in this Agreement, neither the Junior
Agent nor any Junior Lender shall have any duty to the Senior Agent or any of
the Senior Lenders to act or refrain from acting in a manner which allows, or
results in, the occurrence or continuance of an event of default or default
under any agreements with GenTek (including, without limitation, the Senior
Lender Documents), regardless of any knowledge thereof which they may have or be
charged with.

        7.3 No Waiver of Lien Priorities.

        (a) No right of the Senior Lenders, the Senior Agent or any of them to
enforce any provision of this Agreement shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of any GenTek
Obligor or by any act or failure to act by any Senior Lender or the Senior
Agent, or by any noncompliance by any Person with the terms, provisions and
covenants of this Agreement, any of the Senior Lender Documents or any of the
Junior Lender Documents, regardless of any knowledge thereof which the Senior
Agent or the Senior Lenders, or any of them, may have or be otherwise charged
with. No right of the Junior Lenders, the Junior Agent or any of them to enforce

paragraph (but subject to the rights of the GenTek Obligors under the Senior
Lender Documents), the Senior Lenders, the Senior Agent and any of them may, at
any time and from time to time, without the consent of, or notice to, the Junior
Agent or any Junior Lender, without incurring any liabilities to the Junior
Agent or any Junior Lender and without impairing or releasing the lien
priorities and other benefits provided in this Agreement (even if any right of
subrogation or other right or remedy of the Junior Agent or any Junior Lender is
affected, impaired or extinguished thereby) do any one or more of the following:

            (i)   change the manner, place or terms of payment or change or

        directly or indirectly in respect thereof;

            (iii) settle or compromise any Senior Lender Claim or any other
        liability of any GenTek Obligor (other than the Junior Lender Claims) or
        any security therefor or any liability incurred directly or indirectly
        in respect thereof and apply any

        thereof.

                                       17









<PAGE>

instance involved and shall in no way impair the rights of the parties making

time to provide any such information to the Junior Agent or any Junior Lender,
or in the event the Junior Agent or any of the Junior Lenders, in its or their
sole discretion, undertakes at any time or from time to time to provide any such
information to the Senior Agent or any Senior Lender, such provider of
information shall be under no obligation (x) to provide any additional
information or to provide any such information on any subsequent occasion, (y)
to undertake any investigation or (z) to disclose any information which,
pursuant to accepted or reasonable commercial finance practices, such party
wishes to maintain confidential.

Lenders, hereby waives any rights of subrogation it may acquire as a result of
any payment hereunder until the Discharge of Senior Lender Claims has occurred.

        8.6 Application of Payments. All payments received by the Senior Lenders
may be applied, reversed and reapplied, in whole or in part, to such part of the
