         respect thereto.

                (iii) Such Lien Grantor has good and marketable title to all
         its Collateral (subject to exceptions that are, in the aggregate, not
         material), free and clear of any Lien other than Permitted Liens.

                 (iv) Such Lien Grantor has not performed any acts that could
         reasonably be expected to prevent the Collateral Agent from enforcing
         any of the provisions of the Security Documents or that would limit the
         Collateral Agent in any such enforcement (it being understood, and the
         parties hereto having acknowledged pursuant to Section 5, that certain
         restrictions on such enforcement exist under applicable law). No
         financing statement, security agreement, mortgage or similar or
         equivalent document or instrument covering all or part of the
         Collateral owned by such Lien Grantor is on file or of record in any
         jurisdiction in which such filing or recording would be effective to
         perfect or record a Lien on such Collateral, except financing
         statements, mortgages or other similar or equivalent documents with
         respect to Permitted Liens.

                  (v) The Transaction Liens on all Collateral owned by such Lien
         Grantor (i) have been validly created, (ii) will attach to each item of
         such Collateral on the Effective Date (or, if such Lien Grantor first
         obtains rights thereto on a later date, on such later date) and (iii)
         when so attached, will secure all the Secured Obligations purported to
         be secured by such item of Collateral pursuant to Section 2.

                 (vi) Such Lien Grantor has delivered a Perfection Certificate
         to the Collateral Agent. The information set forth therein is correct
         and complete as of the Effective Date. Within 60 days after the
         Effective Date, such Lien Grantor will furnish to the Collateral Agent
         a file search report

                                       21
<PAGE>

         from each UCC filing office listed in its Perfection Certificate,
         showing the filing made at such filing office to perfect the
         Transaction Liens on its Collateral.

                (vii) When UCC financing statements describing the Collateral
         as set forth in Schedule 2 to such Lien Grantor's Perfection
         Certificate have been filed in the offices specified in such Perfection
         Certificate, the Transaction Liens will constitute perfected security
         interests in the Collateral owned by such Lien Grantor to the extent
         that a security interest therein may be perfected by filing pursuant to
         the UCC, prior to all Liens and rights of others therein except
         Permitted Liens. Except for the filing of such UCC financing
         statements, (and, in the case of Transaction Liens granted by QwestDex,
         (x) the filing of certain intellectual property filings, (y) the due
         recordation of mortgages and (z) the filing of assignments and notices
         of assignment with the relevant Governmental Authority regarding
         government contracts between such Lien Grantor and a Governmental
         Authority), no registration, recordation or filing with any
         governmental body, agency or official is required in connection with
         the execution or delivery of the Security Documents or is necessary for
         the validity or (except as otherwise set forth in Section 5)
         enforceability thereof or for the perfection or due recordation of the
         Transaction Liens or (except as otherwise set forth in Section 5) for
         the enforcement of the Transaction Liens.

         (b) In addition to the representations and warranties set forth in
subsection (a) above, QwestDex represents and warrants that:

                  (i) As of the Effective Date, such Lien Grantor does not own
         any Equity Interests in Subsidiaries or Affiliates.

                 (ii) Schedule 1 lists, as of the Effective Date, all
         Securities owned by such Lien Grantor.

                (iii) Such Lien Grantor has taken, and will continue to take,
         all actions necessary under the UCC to perfect its interest in (i) any
         Accounts or Chattel Paper purchased or otherwise acquired by it, as
         against its assignors and creditors of its assignors and (ii) any
         Payment Intangibles or promissory notes purchased or otherwise acquired
         by it, as against its assignors and creditors of its assignors.

                 (iv) Such Lien Grantor's Collateral is insured as required by
         the Credit Agreement.

                                       22
<PAGE>

                  (v) All of such Lien Grantor's Inventory has or will have been
         produced in compliance with the applicable requirements of the Fair
         Labor Standards Act, as amended.

         (c) In addition to the representations and warranties set forth in
subsection (a) of this Section 3, each of QSC and QwestDex Holdings represents
and warrants that:

                  (i) Schedule 2 lists all of the notes or other Instruments
         evidencing Debt owing to such Lien Grantor as of the Effective Date.

                 (ii) As of the Effective Date, such Lien Grantor has delivered
         to the Collateral Agent as Collateral hereunder all notes and
         Instruments evidencing Debt owing to such Lien Grantor.

         SECTION 4. Further Assurances; General Covenants. Each Lien Grantor
covenants as follows:

         (a) Such Lien Grantor will, from time to time, at the Borrowers'
expense, execute, deliver, file and record any statement, assignment,
instrument, document, agreement or other paper and take any other action
(including any filing of financing or continuation statements under the UCC)
that from time to time may be necessary or desirable, or that the Collateral
Agent may request, in order to:

                  (i) create, preserve, perfect, confirm or validate the
         Transaction Liens on such Lien Grantor's Collateral;

                 (ii) enable the Collateral Agent and the other Secured Parties
         to obtain the full benefits of the Security Documents; or

                (iii) enable the Collateral Agent to exercise and enforce any
         of its rights, powers and remedies with respect to any of such Lien
         Grantor's Collateral;

provided that no Lien Grantor will be required to take any action with respect
to (u) delivering Instruments other than as provided in Section 7, (v)
delivering letters of credit other than as provided in Section 10, (w) recording
mortgages and/or fixture filings, (x) filing with the United States Patent and

<PAGE>

account control agreement with respect to any Security Entitlement or deposit
account control agreement with respect to any Deposit Account; provided further
that no Lien Grantor shall be required to deliver an Opinion of Counsel in order
to satisfy its obligations under this Section 4(a), except to the extent that
delivery of such Opinion of Counsel is otherwise expressly required pursuant to
this Agreement.

To the extent permitted by applicable law, such Lien Grantor authorizes the
Collateral Agent to execute and file such financing statements or continuation
statements without such Lien Grantor's signature appearing thereon. Such Lien
Grantor agrees that a carbon, photographic, photostatic or other reproduction of
this Agreement or of a financing statement is sufficient as a financing
statement. Such Lien Grantor constitutes the Collateral Agent its
attorney-in-fact to execute all filings required or so requested for the
foregoing purposes (subject to the limitations set forth in the first proviso
above), all acts of such attorney being hereby ratified and confirmed; and such
power, being coupled with an interest, shall be irrevocable until all the
Transaction Liens granted by such Lien Grantor terminate pursuant to Section 27.
The Borrowers will pay the costs of, or incidental to, any recording or filing
of any financing or continuation statements or other documents recorded or filed
pursuant hereto.

         (b) Such Lien Grantor will not (i) change its name or corporate
structure, (ii) change its location (determined as provided in UCC Section
9-307) or (iii) become bound, as provided in UCC Section 9-203(d) or otherwise,
by a security agreement entered into by another Person, unless it shall have
given the Collateral Agent prior notice thereof and delivered an Opinion of
Counsel with respect thereto in accordance with Section 4(c); provided that no
such Opinion of Counsel shall be required in connection with the actions
described in clause (iii) (and such actions shall not be prohibited ) if the
relevant security agreement creates Liens that are not prohibited under either
Credit Agreement.

         (c) At least 30 days before it takes any action contemplated by Section
4(b) (other than any action described in the proviso to such Section), such Lien
Grantor will, at the Borrowers' expense, cause to be delivered to the Collateral
Agent an Opinion of Counsel, in form and substance satisfactory to the
Collateral Agent, to the effect that (i) all financing statements and amendments
or supplements thereto, continuation statements and other documents required to
be filed or recorded in order to perfect the Transaction Liens (to the extent
such Liens can be perfected by filing pursuant to the UCC) against all creditors
of and purchasers from such Lien Grantor after it takes such action (except any
continuation statements specified in such Opinion of Counsel that are to be
filed more than six months after the date thereof) have been filed or recorded
in each office necessary for such purpose, (ii) all fees and taxes, if any,
payable in

                                       24
<PAGE>

connection with such filings or recordations have been paid in full and (iii)
except as otherwise agreed by the Required Secured Lenders, such action will not
adversely affect the perfection or priority of the Transaction Lien on any
Collateral to be owned by such Lien Grantor after it takes such action or the
accuracy of such Lien Grantor's representations and warranties herein relating
to such Collateral.

         (d) Such Lien Grantor will not sell, lease, exchange, assign or
otherwise dispose of, or grant any option with respect to, any of its
Collateral; provided that such Lien Grantor may do any of the foregoing unless
(i) doing so would violate a covenant in one or both of the Credit Agreements or
(ii) an Event of Default shall have occurred and be continuing and the
Collateral Agent shall have notified such Lien Grantor that its right to do so
is terminated, suspended or otherwise limited. Concurrently with any sale, lease
or other disposition (except a sale or disposition to another Lien Grantor or a
lease) permitted by the foregoing proviso, the Transaction Liens on the assets
sold or disposed of (but not in any Proceeds arising from such sale or
disposition) will cease immediately without any action by the Collateral Agent
or any other Secured Party. The Collateral Agent will, at the Borrowers'
expense, execute and deliver to the relevant Lien Grantor such documents as such
Lien Grantor shall reasonably request to evidence the fact that any asset so
sold or disposed of is no longer subject to a Transaction Lien.

         (e) Such Lien Grantor will, promptly upon request, provide to the
Collateral Agent all information and evidence concerning such Lien Grantor's
Collateral that the Collateral Agent may reasonably request from time to time to
enable it to enforce the provisions of the Security Documents.

         (f) Such Lien Grantor agrees to exercise commercially reasonable
efforts:

                  (i) to cooperate with the Collateral Agent to obtain any
         approval of the FCC or the PUCs for any action or transaction
         contemplated by this Agreement which is then required by applicable law
         (provided that no Lien Grantor shall be required to seek or obtain such
         FCC or PUC approval of any grant of Transaction Liens with respect to
         any Holdings Asset Collateral or any QwestDex Asset Collateral located
         in, or attributable to, the State of Washington or the State of Utah);
         and

                 (ii) after the occurrence of an Event of Default, cooperate
         with the Collateral Agent to obtain any approval of the FCC, any PUC
         and any other Governmental Authority which may be required, necessary
         or appropriate under the FCC's, such PUC's or such Governmental

                                       25

         Authority's rules and regulations in connection with any sale or
         transfer of any of the capital stock or assets of a Borrower or any of
         its Subsidiaries.

applicable law, the PUCs or other Governmental Authorities, take any action
pursuant to this Agreement, any Revolver Loan Document or any Term Loan

limitation any exercise of remedies, that would constitute or result in:

                           (C) Preventing or restricting any Lien Grantor from
                  exercising its power to vote, or give consents with respect

         Loans;

                 (iv) The sale, disposition or transfer of the capital stock of
         Corp.; and

                  (v) Calling any meeting of shareholders or of the Board of
         Directors of Corp. (or any committee thereof) or voting, giving consent
         or exercising any other right as a shareholder of Corp.

         (d) The Collateral Agent on behalf of the Secured Parties acknowledges
and recognizes that a QwestDex Company may be a Regulated Entity in certain
States, and that the ability of creditors (including the Secured Parties) to
exercise rights in connection with any pledge of, or security interest in, the

restrictions or prohibitions, before or after any default by such Lien Grantor,
on the right of any Person (i) to acquire control of a QwestDex Company without
the prior consent of certain PUCs or (ii) to foreclose on, or otherwise acquire
ownership of, the capital stock of a QwestDex Company or the QwestDex Asset
Collateral.

         (e) The Collateral Agent on behalf of the Secured Parties acknowledges
and agrees that the pledge of the capital stock or assets of a QwestDex Company
does not afford the Secured Parties (or any other creditor of the applicable
Lien Grantor) ownership of, or the right or power to vote, such capital stock or
the right or power to control the operations, management or policies of such
QwestDex Company.

         (f) The Collateral Agent agrees that, notwithstanding anything to the
contrary contained in this Agreement, any Revolver Loan Document or any Term

<PAGE>

Agreement, any Revolver Loan Document or any Term Loan Document, whether before
or after any Event of Default, including without limitation any exercise of
remedies, that would constitute or result in:

                  (i) The exercise by the Collateral Agent of control over a
         QwestDex Company, any of its Subsidiaries or any of its assets,

         SECTION 6. Accounts. Each Lien Grantor whose Collateral includes
Pledged Accounts represents, warrants and covenants as follows:

         (a) Such Lien Grantor will use commercially reasonable efforts to cause
to be collected from its account debtors, when due, all amounts owing under its
Accounts (including delinquent Accounts, which will be collected in accordance
with lawful collection procedures) and will apply all amounts collected thereon,
forthwith upon receipt thereof, to the outstanding balances of such Accounts.
Subject to the rights of the Collateral Agent and the other Secured Parties

                                       28
<PAGE>

hereunder if an Event of Default shall have occurred and be continuing, such
Lien Grantor may allow in the ordinary course of business as adjustments to
amounts owing under its Accounts (i) any extension or renewal of the time or
times for payment, or settlement for less than the total unpaid balance, that
such Lien Grantor finds appropriate in accordance with sound business judgment
and (ii) refunds or credits, all in the ordinary course of business and
consistent with such Lien Grantor's historical collection practices. The costs
and expenses (including attorney's fees) of collection, whether incurred by such
Lien Grantor or the Collateral Agent, shall be paid by such Lien Grantor.

         (b) If an Event of Default shall have occurred and be continuing, such
Lien Grantor will, if requested to do so by the Collateral Agent, promptly
notify (and such Lien Grantor authorizes the Collateral Agent so to notify) each
account debtor in respect of any of its Accounts that such Accounts have been
assigned to the Collateral Agent hereunder, and that any payments due or to
become due in respect of such Accounts are to be made directly to the Collateral
Agent or its designee.

         SECTION 7. Instruments. Except as to actions to be taken by the
Collateral Agent, each Lien Grantor whose Collateral includes Pledged
Instruments represents, warrants and covenants as follows:

         (a) On the Effective Date (in the case of an Original Lien Grantor) or
the date on which it signs and delivers its first Security and Pledge Agreement
Supplement (in the case of any other Lien Grantor), such Lien Grantor will
deliver to the Collateral Agent as Collateral hereunder all Pledged Instruments
then owned by such Lien Grantor; provided that the Lien Grantor shall not be
required to deliver any Pledged Instrument to the Collateral Agent if (x) the
obligor under such Pledged Instrument is not an Affiliate of QwestDex and (y)
the aggregate principal or face amount of such instrument does not exceed
$500,000 and (z) the sum of the aggregate principal or face amount of such
instrument and the aggregate principal or face amount of all other Pledged

does not exceed $5,000,000. Thereafter, whenever such Lien Grantor acquires any
such Pledged Instrument, such Lien Grantor will immediately deliver such Pledged
Instrument to the Collateral Agent as Collateral hereunder, subject to the
proviso in the previous sentence.

         (b) So long as no Event of Default shall have occurred and be
continuing, the Collateral Agent will, promptly upon request by the relevant
Lien Grantor, make appropriate arrangements for making any Pledged Instrument
available to it for purposes of presentation, collection or renewal (any such
arrangement to be

trust receipt or like document).

         (c) All Pledged Instruments owned by such Lien Grantor, when delivered
to the Collateral Agent, will be indorsed to the order of the Collateral Agent,
or accompanied by duly executed instruments of assignment, with signatures
appropriately guaranteed, all in form and substance satisfactory to the
Collateral Agent.

         (d) Upon the delivery of any Pledged Instrument owned by such Lien
Grantor to the Collateral Agent, the Transaction Lien on such Collateral will be
perfected, subject to no prior Liens or rights of others.

         SECTION 8. Commercial Tort Claims. Each Lien Grantor whose Collateral
includes Commercial Tort Claims represents, warrants and covenants as follows:

         (a) In the case of an Original Lien Grantor whose Collateral includes
Commercial Tort Claims, Schedule 3 accurately describes, with the specificity
required to satisfy Official Comment 5 to UCC Section 9-108, each Material
Commercial Tort Claim with respect to which such Original Lien Grantor is the
claimant as of the Effective Date. In the case of any other Lien Grantor whose
Collateral includes Commercial Tort Claims, Schedule 3 to its first Security and
Pledge Agreement Supplement will accurately describe, with the specificity
required to satisfy said Official Comment 5, each Material Commercial Tort Claim
with respect to which such Lien Grantor is the claimant as of the date on which
it signs and delivers such Security and Pledge Agreement Supplement.

         (b) If any Lien Grantor whose Collateral includes Commercial Tort
Claims acquires a Material Commercial Tort Claim after the Effective Date (in
the case of an Original Lien Grantor) or the date on which it signs and delivers
its first Security and Pledge Agreement Supplement (in the case of any other
Lien Grantor), such Lien Grantor will promptly sign and deliver to the
Collateral Agent a Security and Pledge Agreement Supplement granting a security
interest in such Commercial Tort Claim (which shall be described therein with
the specificity required to satisfy said Official Comment 5) to the Collateral
Agent for the benefit of the Secured Parties.

         (c) Upon the filing of a UCC financing statement in the jurisdiction
under the laws of which the relevant Lien Grantor is organized, the Transaction
Lien on each Material Commercial Tort Claim described pursuant to subsection (a)
or (b) above will be perfected, subject to no prior Liens or rights of others.

         SECTION 9. [Intentionally Omitted].

         SECTION 10. Proceeds of Letters of Credit. Except as to actions to be
taken by the Collateral Agent, each Lien Grantor whose Collateral includes
Letter- of-Credit Rights represents, warrants and covenants that if an Event of
Default shall have occurred and be continuing, such Lien Grantor will, promptly
upon request by the Collateral Agent, deliver all letters of credit to which it
is a beneficiary to the Collateral Agent and notify (and such Lien Grantor
authorizes the Collateral Agent to notify) the issuer and each Nominated Person
with respect to each of its Pledged letters of credit that (i) the proceeds
thereof have been assigned to the Collateral Agent hereunder and (ii) any
payments due or to become due in respect thereof are to be made directly to the
Collateral Agent or its designee.

         SECTION 11. Investment Property. Each Lien Grantor whose Collateral
includes Investment Property represents, warrants and covenants as follows:

         (a) Certificated Securities. On the Effective Date (in the case of an
Original Lien Grantor) or the date on which it signs and delivers its first
Security and Pledge Agreement Supplement (in the case of any other Lien
Grantor), such Lien Grantor will deliver to the Collateral Agent as Collateral
hereunder all certificates representing Pledged Certificated Securities then
owned by such Lien Grantor. Thereafter, whenever such Lien Grantor acquires any

         The Collateral Agent may make such distributions hereunder in cash or
in kind or, on a ratable basis, in any combination thereof.

         (d) If at any time any portion of any monies collected or received by
the Collateral Agent would, but for the provisions of this Section 21(d), be
payable pursuant to Section 21(a), 21(b), 21(c) in respect of a Contingent
Secured Obligation, the Collateral Agent shall not apply any monies to pay such
Contingent Secured Obligation but instead shall request the holder thereof, at
least 10 days before each proposed distribution hereunder, to notify the
Collateral Agent as to the maximum amount of such Contingent Secured Obligation
if then ascertainable. If the holder of such Contingent Secured Obligation does
not notify the Collateral Agent of the maximum ascertainable amount thereof at
least two Business Days before such distribution, such holder will not be
entitled to share in such distribution. If such holder does so notify the
Collateral Agent as to the maximum ascertainable amount thereof, the Collateral
Agent will allocate to such holder a portion of the monies to be distributed in
such distribution, calculated as if such Contingent Secured Obligation were
outstanding in such maximum ascertainable amount. However, the Collateral Agent
will not apply such portion of such monies to pay such Contingent Secured
Obligation, but instead will hold such monies or invest such monies in Liquid
Investments. All such monies and Liquid Investments and all proceeds thereof
will constitute Collateral hereunder, but will be subject to distribution in
accordance with this Section 21(d) rather than Section 21(a), 21(b), 21(c), as
applicable. The Collateral Agent will hold all such monies and Liquid
Investments and the net proceeds thereof in trust until all or part of such
Contingent Secured Obligation becomes a Non-Contingent Secured Obligation,
whereupon the Collateral Agent at the request of the relevant Secured Party will
apply the amount so held in trust to pay such Non-Contingent Secured Obligation;
provided that, if the other Secured Obligations theretofore paid pursuant to the
same clause of Section 21(a), 21(b), 21(c), as applicable (i.e., clause second,
fourth or fifth) were not paid in full, the Collateral Agent will apply the
amount so held in trust to pay the same percentage of such Non-Contingent
Secured Obligation as the percentage of such other Secured Obligations
theretofore paid pursuant to the same clause of Section 21(a), 21(b), 21(c), as
applicable. If (i) the holder of such Contingent Secured Obligation shall advise
the Collateral Agent that no portion thereof remains in the category of a
Contingent Secured Obligation and (ii) the Collateral Agent still holds any

                                       41

amount held in trust pursuant to this Section 21(d) in respect of such
Contingent Secured Obligation (after paying all amounts payable pursuant to the
preceding sentence with respect to any portions thereof that became
Non-Contingent Secured Obligations), such remaining amount will be applied by
the Collateral Agent in the order of priorities set forth in Section 21(a),
21(b), 21(c), as applicable.

          (e) In making the payments and allocations required by this Section,
the Collateral Agent may rely upon information supplied to it pursuant to
Section 26(f). All distributions made by the Collateral Agent pursuant to this
Section shall be final (except in the event of manifest error) and the
Collateral Agent shall have no duty to inquire as to the application by any
Secured Party of any amount distributed to it.

                  this Section 22(a), the "Silent Revolver Collateral
                  Lienholders") shall assert, or make any request or demand upon

                  in connection with any Bankruptcy Event in respect of any Loan
                  Party which could otherwise be asserted or raised in
                  connection with such Bankruptcy Event by any Silent Revolver

                  capacity as such) as a creditor and/or equity holder of the
                  applicable Loan Party, including without limitation any claim,
                  motion, objection or argument seeking or opposing adequate
                  protection or relief from the automatic stay in respect of the
                  First Tier Revolver Collateral.

                           (B) until such time as all Term Secured Obligations

                  shall assert, or make any request or demand upon the
                  Collateral Agent to assert any claim,

                                       42

                  motion, objection, or argument in respect of the First Tier
                  Term Collateral in connection with any Bankruptcy Event in
                  respect of any Loan Party which could otherwise be asserted or
                  raised in connection with such Bankruptcy Event by any Silent
                  Term Collateral Lienholder (in each case, in its capacity as
                  such) as a creditor and/or equity holder of the applicable
                  Loan Party, including without limitation any claim, motion,

                           (B) the Collateral Agent (on behalf of the Secured
                  Term Lender Parties) may, without seeking or obtaining the
                  consent of the Silent Term Collateral Lienholders as holders
                  of an interest in the First Tier Term Collateral, contest or
                  consent to the use of cash collateral (excluding Collateral
                  that is not First Tier Term Collateral) on such terms and
                  conditions and in such amounts as the Secured Term Parties, in

                  accordance with the Revolver Credit Agreement, consent to
                  postpetition financing (whether provided by a Secured Revolver
                  Lender Party or by a third party) for QSC and its Subsidiaries
                  secured by a priority lien on the First Tier Revolver
                  Collateral, in each case pursuant to Section 364 of the
                  Bankruptcy Code or other applicable law and on such terms and
                  conditions and in such amounts as such Secured Revolver Lender
                  Parties, in their sole discretion, may decide, without seeking
                  or obtaining the consent of the Silent Revolver Collateral
                  Lienholders as holders of an interest in the First Tier
                  Revolver Collateral, and none of the Silent

<PAGE>

                  Revolver Collateral Lienholders (in each case, in their
                  respective capacities as such) shall oppose such financing (or
                  the granting of a priority lien on the First Tier Revolver
                  Collateral in connection therewith) as holders of an interest
                  in the First Tier Revolver Collateral, and (2) the Secured
                  Term Lender Parties may, in accordance with the Term Credit
                  Agreement, consent to postpetition financing (whether provided
                  by a Secured Term Lender Party or by a third party) for the
                  QSC and its Subsidiaries secured by a priority lien on the
                  First Tier Term Collateral, in each case pursuant to Section
                  364 of the Bankruptcy Code or other applicable law and on such
                  terms and conditions and in such amounts as such Secured Term
                  Lender Parties, in their sole discretion, may decide, without
                  seeking or obtaining the consent of Silent Term Collateral
                  Lienholders as holders of an interest in the First Tier Term
                  Collateral, and none of the Silent Term Collateral Lienholders
                  (in each case, in their respective capacities as such) shall
                  oppose such financing (or the granting of a priority lien on
                  First Tier Revolver Collateral in connection therewith) as
                  holders of an interest in the First Tier Term Collateral;

                  Lienholders shall oppose the use by any Loan Party of cash
                  collateral (excluding Collateral that is not First Tier
                  Revolver Collateral or Proceeds thereof) on the basis that its
                  interest in the First Tier Revolver Collateral is impaired by
                  such use or inadequately protected by such use to the extent
                  such use has been approved by the Secured Revolver Lender
                  Parties in accordance with the Revolver Credit Agreement, and
                  (2) none of the Silent Term Collateral Lienholders (in each
                  case, in their respective capacities as such) shall oppose the
                  use by any Loan Party of cash collateral (excluding Collateral
                  that is not First Tier Term Collateral or Proceeds thereof) on
                  the basis that its interest in the First Tier Term Collateral
                  is impaired by such use or inadequately protected by such use
                  to the extent such use has been approved by the Secured Term
                  Lender Parties in accordance with the Term Credit Agreement;
                  and

                           (E) (1) none of the Silent Revolver Collateral
                  Lienholders shall oppose any sale or other disposition of any
                  assets comprising part of the First Tier Revolver Collateral

                  any party, including the Silent Revolver Collateral
                  Lienholders, under Section 363 of the Bankruptcy Code on the
                  basis that the interest of the Silent

<PAGE>

                  Revolver Collateral Lienholders in the First Tier Revolver
                  Collateral is impaired by such sale or inadequately protected
                  as a result of such sale if the Secured Revolver Lender
                  Parties have consented to such sale or disposition of such
                  assets in accordance with the Revolver Credit Agreement, and
                  (2) none of the Silent Term Collateral Lienholders shall
                  oppose any sale or other disposition of any assets comprising
                  part of the First Tier Term Collateral free and clear of
                  security interests, liens or other claims of any party,
                  including the Silent Term Collateral Lienholders, under
                  Section 363 of the Bankruptcy Code on the basis that the
                  interest of the Silent Term Collateral Lienholders in the
                  First Tier Term Collateral is impaired by such sale or
                  inadequately protected as a result of such sale if the Secured
                  Term Parties have consented to such sale or disposition of
                  such asset in accordance with the Term Credit Agreement.

                (iii) (A) To the extent that any Secured Revolver Party (in
         its capacity as such) realizes any amounts, or otherwise receives any
         payments, with respect to any First Tier Revolver Collateral (or
         Proceeds thereof) which payments are subsequently invalidated, declared
         to be fraudulent or preferential, set aside and/or required to be
         repaid to a trustee, receiver or any other party under any bankruptcy
         law, state or federal law, common law, or equitable cause, then, to the
         extent of such payment or proceeds received, the Revolver Secured
         Obligations, or part thereof, intended to be satisfied shall be revived
         and continue in full force and effect enjoying all rights and benefits
         of this Agreement as if such payments or proceeds had not been received
         by such Secured Revolver Party.

                           (B) To the extent that any Secured Term Party (in its
                  capacity as such) realizes any amounts, or otherwise receives
                  any payments, in respect of the First Tier Term Collateral (or
                  Proceeds thereof) which payments are subsequently invalidated,
                  declared to be fraudulent or preferential, set aside and/or
                  required to be repaid to a trustee, receiver or any other
                  party under any bankruptcy law, state or federal law, common
                  law, or equitable cause, then, to the extent of such payment
                  or proceeds received, the Term Secured Obligations, or part
                  thereof, intended to be satisfied shall be revived and
                  continue in full force and effect enjoying all rights and
                  benefits of this Agreement as if such payments or proceeds had
                  not been received by such Secured Term Party.

                 (iv) Notwithstanding any other provision of this Section
         22(a), each of the Secured Revolver Parties, the Secured Term Parties
         and the Junior Secured Parties (in their respective capacities as such)
         shall be entitled to file any necessary responsive or defensive
         pleadings in opposition to any motion, claim, adversary proceeding or
         other pleading made by any person objecting to or otherwise seeking the
         disallowance of the claims of the Secured Revolver Parties or the
         Secured Term Parties (in their respective capacities as such),
         including, without limitation, (A) claims of the Secured Revolver
         Parties secured by the First Tier Term Collateral, if any, and (B)
         claims of the Secured Term Parties secured by the First Tier Revolver
         Collateral, if any.

         (b) (i) All rights and interests of the Secured Revolver Lender

                  other Loan Document or any other agreement or instrument
                  relating thereto;

                           (B) any change in the time, manner or place of, or in
                  any other term of, all or any of the Revolver Secured

                  departure from any provision of the Revolver Credit Agreement
                  or any other Revolver Loan Document, provided that such
                  change, amendment, waiver or consent is permitted pursuant to
                  the terms of the Revolver Credit Agreement and the other
                  Revolver Loan Documents;

                           (C) any change in the time, manner or place of, or in

<PAGE>

                           (D) any exchange, release, nonperfection, or
                  unenforceability of any lien or security interest in any
                  Collateral, or any release or amendment or waiver of or
                  consent to departure from any guarantee, for all or any of the
                  Revolver Secured Obligations or all or any of the Term Secured
                  Obligations, as applicable; or

                           (E) any other circumstances which might otherwise
                  constitute a defense available to, or a discharge of, any Loan
                  Party in respect of the Revolver Secured Obligations, the Term
                  Secured Obligations or any other Secured Obligation, as the
                  case may be.

         SECTION 23. Fees and Expenses; Indemnification. (a) Each Borrower will
forthwith upon demand pay to the Collateral Agent the amount of any fees that
the Borrowers shall have agreed in writing to pay to the Collateral Agent and
that shall have become due and payable in accordance with such written
agreement. Additionally, the Borrowers jointly and severally agree to pay to the
Collateral Agent forthwith upon demand:

                  (i) the amount of any taxes that the Collateral Agent may have
         been required to pay by reason of the Transaction Liens or to free any
         Collateral from any other Lien thereon that is not a Permitted Lien;

                 (ii) the amount of any and all reasonable out-of-pocket
         expenses, including transfer taxes and reasonable fees and expenses of
         counsel and other experts, that the Collateral Agent may incur in
         connection with (x) the administration or enforcement of the Security
         Documents, including such reasonable expenses as are incurred to
         preserve the value of the Collateral or the validity, perfection, rank
         or value of any Transaction Lien, (y) the collection, sale or other
         disposition of any Collateral or (z) the exercise by the Collateral
         Agent of any of its rights or powers under and in accordance with the
         Security Documents; and

                 (iii) the amount required to indemnify the Collateral Agent
         for, or hold it harmless and defend it against (in each case, to the
         extent permitted by law), any loss, liability or expense (including the
         reasonable fees and expenses of its counsel and any experts or
         sub-agents appointed by it hereunder) incurred or suffered by the
         Collateral Agent in connection with the Security Documents, except to
         the extent that such loss, liability or expense arises from the
         Collateral Agent's gross negligence or willful misconduct.

                                       47
<PAGE>

Any such amount not paid to the Collateral Agent on demand will bear interest
for each day thereafter until paid at a rate per annum equal to the sum of 2%
plus (x) so long as any Term Loans are outstanding, the rate applicable to Base
Rate Loans under (and as defined in) the Term Credit Agreement for such day or
(y) if no Term Loans are outstanding, the rate applicable to Base Rate Loans
under (and as defined in) the Revolver Credit Agreement for such day.

         (b) If any transfer tax, documentary stamp tax or other tax is payable
in connection with any transfer or other transaction provided for in the
Security Documents, the Borrowers jointly and severally agree to pay such tax
and provide any required tax stamps to the Collateral Agent or as otherwise
required by law.

         SECTION 24. Authority to Administer Collateral. Each Lien Grantor
irrevocably appoints the Collateral Agent its true and lawful attorney, with
full power of substitution, in the name of such Lien Grantor, any Secured Party
or otherwise, for the sole use and benefit of the Secured Parties, but at the
Borrowers' expense, to the extent permitted by law to exercise, at any time and
from time to time while an Event of Default shall have occurred and be
continuing, all or any of the following powers with respect to all or any of
such Lien Grantor's Collateral:

                  (a) to demand, sue for, collect, receive and give acquittance
         for any and all monies due or to become due upon or by virtue thereof,

                  (b) to settle, compromise, compound, prosecute or defend any
         action or proceeding with respect thereto,

                  (c) to sell, lease, license or otherwise dispose of the same
         or the proceeds or avails thereof, as fully and effectually as if the
         Collateral Agent were the absolute owner thereof, and

                  (d) to extend the time of payment of any or all thereof and to
         make any allowance or other adjustment with reference thereto;

provided that, except in the case of Collateral that is perishable or threatens
to decline speedily in value or is of a type customarily sold on a recognized
market, the Collateral Agent will give the relevant Lien Grantor at least ten
days' prior written notice of the time and place of any public sale thereof or
the time after which any private sale or other intended disposition thereof will
be made. Any such notice shall (i) contain the information specified in UCC
Section 9-613, (ii) be Authenticated and (iii) be sent to the parties required
to be notified pursuant to UCC Section 9-611(c); provided that, if the
Collateral Agent fails to comply with

                                       48
<PAGE>

this sentence in any respect, its liability for such failure shall be limited to
the liability (if any) imposed on it as a matter of law under the UCC.

         SECTION 25. Limitation on Duty in Respect of Collateral. Beyond the
exercise of reasonable care in the custody and preservation thereof, the
Collateral Agent will have no duty as to any Collateral in its possession or
control or in the possession or control of any sub-agent or bailee or any income
therefrom or as to the preservation of rights against prior parties or any other
rights pertaining thereto. The Collateral Agent will be deemed to have exercised
reasonable care in the custody and preservation of the Collateral in its
possession or control if such Collateral is accorded treatment substantially
equal to that which it accords its own property, and will not be liable or
responsible for any loss or damage to any Collateral, or for any diminution in
the value thereof, by reason of any act or omission of any sub-agent or bailee
selected by the Collateral Agent in good faith, except to the extent that such
liability arises from the Collateral Agent's gross negligence or willful
misconduct.

         SECTION 26. General Provisions Concerning the Collateral Agent. (a)
Authority. The Collateral Agent is authorized to take such actions and to
exercise such powers as are delegated to the Collateral Agent by the terms of
the Security Documents, together with such actions and powers as are reasonably
incidental thereto.

         (b) Rights and Powers as a Secured Party. The bank serving as the
Collateral Agent shall, in its capacity as a Secured Party, have the same rights
and powers as any other Secured Party and may exercise the same as though it
were not the Collateral Agent. Such bank and its Affiliates may accept deposits
from, lend money to and generally engage in any kind of business with any Qwest
Company or Affiliate thereof as if it were not the Collateral Agent hereunder.

         (c) Limited Duties and Responsibilities. The Collateral Agent shall not
have any duties or obligations under the Security Documents except those
expressly set forth therein. Without limiting the generality of the foregoing,
(a) the Collateral Agent shall not be subject to any fiduciary or other implied
duties, regardless of whether an Event of Default has occurred and is
continuing, (b) the Collateral Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated by the Security Documents that the
Collateral Agent is required in writing to exercise by a majority of the holders
at any time of the relevant First Tier Obligations (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 27(f) of this Agreement), and (c) except as expressly set
forth in the Loan Documents, the Collateral Agent shall not have any duty to
disclose, and shall not be liable for any

                                       49
<PAGE>

failure to disclose, any information relating to any Qwest Company that is
communicated to or obtained by the bank serving as Collateral Agent or any of
its Affiliates in any capacity. The Collateral Agent shall not be liable for any
action taken or not taken by it with the consent or at the request of a majority
of the holders at any time of the relevant First Tier Obligations (or such other
number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 27 of this Agreement) or in the absence of
its own gross negligence or wilful misconduct. The Collateral Agent shall not be
responsible for the existence, genuineness or value of any Collateral or for the
validity, perfection, priority or enforceability of any Transaction Lien,
whether impaired by operation of law or by reason of any action or omission to
act on its part under the Security Documents. The Collateral Agent shall be
deemed not to have knowledge of any Event of Default unless and until written
notice thereof is given to the Collateral Agent by the Administrative Agent
under the Revolver Credit Agreement, the Administrative Agent under the Term
Credit Agreement, a Borrower or a Secured Party, and the Collateral Agent shall
not be responsible for or have any duty to ascertain or inquire into (i) any
statement, warranty or representation made in or in connection with any Security
Document, (ii) the contents of any certificate, report or other document
delivered thereunder or in connection therewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set
forth in any Security Document, (iv) the validity, enforceability, effectiveness
or genuineness of any Security Document or any other agreement, instrument or
document, or (v) the satisfaction of any condition set forth in any Security
Document.

         (d) Authority to Rely on Certain Writings, Statements and Advice. The
Collateral Agent shall be entitled to rely on, and shall not incur any liability
for relying on, any notice, request, certificate, consent, statement,
instrument, document or other writing believed by it to be genuine and to have
been signed or sent by the proper Person. The Collateral Agent also may rely on
any statement made to it orally or by telephone and believed by it to be made by
the proper Person, and shall not incur any liability for relying thereon. The
Collateral Agent may consult with legal counsel (who may be counsel for a Lien
Grantor), independent accountants and other experts selected by it, and shall
not be liable for any action taken or not taken by it in accordance with the
advice of any such counsel, accountant or expert.

         (e) Sub-Agents and Related Parties. The Collateral Agent may perform
any of its duties and exercise any of its rights and powers through one or more
sub-agents appointed by it. The Collateral Agent and any such sub-agent may
perform any of its duties and exercise any of its rights and powers through its
Related Parties. The exculpatory provisions of Section 25 and this Section shall

                                       50
<PAGE>

apply to any such sub-agent and to the Related Parties of the Collateral Agent
and any such sub-agent.

         (f) Information as to Secured Obligations and Actions by Secured
Parties. For all purposes of the Security Documents, including determining the
amounts of the Secured Obligations and whether a Secured Obligation is a
Contingent Secured Obligation or not, or whether any action has been taken under
any Secured Agreement, the Collateral Agent will be entitled to rely on
information from (i) its own records for information as to the Lenders, their
Secured Obligations and actions taken by them, (ii) any Secured Party (or any
trustee, agent or similar representative designated pursuant to Section 29 to
supply such information) for information as to its Secured Obligations and
actions taken by it, to the extent that the Collateral Agent has not obtained
such information from the foregoing sources, and (iii) any Borrower, to the
extent that the Collateral Agent has not obtained information from the foregoing
sources.

         (g) Within two Business Days after it receives or sends any notice
referred to in this subsection, the Collateral Agent shall send to the Lenders
and each Secured Party Requesting Notice, copies of any certificate designating
additional obligations as Secured Obligations received by the Collateral Agent
pursuant to Section 29 and any notice given by the Collateral Agent to any Lien
Grantor, or received by it from any Lien Grantor, pursuant to Section 19, 21,
24, 26(i) or 27.

         (h) The Collateral Agent may refuse to act on any notice, consent,
direction or instruction from any Secured Parties or any agent, trustee or
similar representative thereof that, in the Collateral Agent's opinion, (i) is
contrary to law or the provisions of any Security Document, (ii) may expose the
Collateral Agent to liability (unless the Collateral Agent shall have been
indemnified, to its reasonable satisfaction, for such liability by the Secured
Parties that gave such notice, consent, direction or instruction) or (iii) is
unduly prejudicial to Secured Parties holding First Tier Obligations not joining
in such notice, consent, direction or instruction.

         (i) Resignation; Successor Collateral Agent. The Collateral Agent may
resign at any time by notifying the Lenders and the Borrowers. Upon any such
resignation, the Required Secured Lenders shall have the right, in consultation
with the Borrowers, to appoint a successor Collateral Agent. If no successor
shall have been so appointed by the Required Secured Lenders and shall have
accepted such appointment within 30 days after the retiring Collateral Agent
gives notice of its resignation, then the retiring Collateral Agent may, on
behalf of the Secured Parties, appoint a successor Collateral Agent which shall
be either (i) a bank having (x) an office in New York, New York and (y) combined
capital and

                                       51
<PAGE>

surplus of at least $400,000,000, or an Affiliate of any such bank or (ii)
another bank that is reasonably acceptable to the Borrowers (or an Affiliate of
such bank). Upon acceptance of its appointment as Collateral Agent hereunder by
a successor, such successor shall succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Collateral Agent
hereunder, and the retiring Collateral Agent shall be discharged from its duties
and obligations hereunder. The fees payable by each Borrower to a successor
Collateral Agent shall be the same as those payable by such Borrower to such
Collateral Agent's predecessor unless otherwise agreed by such Borrower and such
successor Collateral Agent. After the Collateral Agent's resignation hereunder,
the provisions of this Section and Section 25 shall continue in effect for the
benefit of such retiring Collateral Agent, its sub-agents and their respective
Related Parties in respect of any actions taken or omitted to be taken by any of
them while the retiring Collateral Agent was acting as Collateral Agent. If no
successor agent has accepted appointment as Collateral Agent by the date which
is 30 days following the retiring Collateral Agent's notice of resignation, the
retiring Agent's resignation shall at its election nevertheless become effective
and the Lenders shall perform all of the duties of the Collateral Agent
hereunder until such time, if any, as the Required Secured Lenders appoint a
successor agent as provided above; provided that if such resignation of the
Collateral Agent becomes effective in accordance with the foregoing sentence
when no Lender is a Secured Party, the Secured Parties at the time of such
resignation, in consultation with the Borrowers, shall appoint a successor
Collateral Agent.

         SECTION 27. Termination of Transaction Liens; Release of Collateral.

         (a) The Transaction Liens granted by each Lien Grantor to secure its
Secured Guarantee shall terminate when its Secured Guarantee is released
pursuant to Section 9.03 of the Revolver Credit Agreement or Section 9.03 of the
Term Credit Agreement, as applicable.

         (b) The Transaction Liens granted by the Revolver Borrower to secure
its Revolver Secured Obligations shall terminate when all the Revolver Release
Conditions are satisfied.

         (c) The Transaction Liens granted by the Term Borrower to secure its
Term Secured Obligations shall terminate when all the Term Release Conditions
are satisfied.

         (d) The Transaction Liens on any QwestDex Asset Collateral that is the
subject of a sale permitted under both the Revolver Credit Agreement and the
Term Credit Agreement shall terminate upon consummation of such permitted asset
sale, whereupon the proceeds from such permitted asset sale shall be applied

                                       52
<PAGE>

in accordance with Section 2.11(c) of the Revolver Credit Agreement and Section
2.11(b) of the Term Credit Agreement.

         (e) The Transaction Liens on all of the QwestDex Asset Collateral will
cease to secure the Revolver Secured Obligations (but shall remain in full force
and effect with respect to any other Secured Obligations then secured by such
Collateral) on the earliest date on which (i) the aggregate Revolver Commitments
have been reduced to an aggregate amount not exceeding $1,250,000,000, (ii) no
obligations are owed by QwestDex to any affiliate of QCII (other than QSC),
(iii) no obligations are owed by QwestDex Holdings to Qwest Capital Funding,
Inc. and (iv) all Transaction Liens on the Pledged Equity Interests in QwestDex
securing the Term Secured Obligations have terminated, such that the Revolver
Secured Obligations are secured by a first priority Transaction Lien on such
Pledged Equity Interests in QwestDex.

         (f) At any time before the Transaction Liens granted by either Borrower
terminate, the Collateral Agent may, at the written request of such Borrower,
(i) release any Collateral (but not (x) all or substantially all of the
Collateral or (y) all or any substantial portion of either the First Tier
Revolver Collateral or the First Tier Term Collateral) with the prior written
consent of the Required Secured Lenders, (ii) release all or any substantial
portion of the First Tier Revolver Collateral with the prior written consent of
all of the Secured Revolver Lender Parties, (iii) release all or any substantial
portion of the First Tier Term Collateral with the prior written consent of all
of the Secured Term Parties or (iv) release all or substantially all of the
Collateral with the prior written consent of all of the Lenders.

         (g) Upon any termination of a Transaction Lien or release of
Collateral, the Collateral Agent will, at the expense of the relevant Lien
Grantor, execute and deliver to such Lien Grantor such documents as such Lien
Grantor shall reasonably request to evidence the termination of such Transaction
Lien or the release of such Collateral, as the case may be.

         SECTION 28. Additional Lien Grantors. Any QwestDex Company may become a
party hereto by signing and delivering to the Collateral Agent a Security and
Pledge Agreement Supplement, whereupon such QwestDex Company shall become a
"Lien Grantor" as defined herein.

         SECTION 29. Additional Permitted Secured Obligations. After the date
hereof, any Lien Grantor may from time to time, designate any other obligation
as an additional secured obligation for purposes hereof (any such additional
secured obligation, an "Additional Permitted Secured Obligation") by delivering
to the Collateral Agent (a) a certificate signed by the chief financial officer
or chief

                                       53
<PAGE>

accounting officer of such Lien Grantor (i) identifying the obligation so
designated and the aggregate principal or face amount thereof, stating that such
obligation is designated as an Additional Permitted Secured Obligation for
purposes hereof, (ii) representing that, after giving effect to the designation
of such obligation as an Additional Permitted Secured Obligation, (x) the
aggregate amount of all Additional Permitted Secured Obligations will not exceed
the sum of $3,000,000,000 plus the aggregate amount of Debt (as defined in the
Revolver Credit Agreement) incurred by the Revolver Borrower in reliance on
Section 5.12(h) of the Revolver Credit Agreement and (y) no default shall have
occurred under any of the Company Indentures and (iii) specifying the name and
address of the holder of such obligation or of a trustee, agent or similar
representative designated to supply information with respect to such additional
Secured Obligation to the Collateral Agent as contemplated by Section 26(f)
and (b) an Additional Secured Party Consent, executed by the holder of such
obligation; provided that no obligation of a Lien Grantor shall be an Additional
Permitted Secured Obligation unless (a) such obligation is permitted under both
the Revolver Credit Agreement and the Term Credit Agreement, (b) the Lien
securing such obligation is permitted by Section 5.07(i)(iv) of the Revolver
Credit Agreement and (c) the Lien securing such obligation is permitted by
Section 5.07 of the Term Credit Agreement.

         SECTION 30. Notices. Each notice, request or other communication given
to any party hereunder shall be in writing (which term includes facsimile) and
shall be effective (i) when delivered to such party at its address specified
below, (ii) when sent to such party by facsimile, addressed to it at its
facsimile number specified below, and such party sends back an electronic
confirmation of receipt or (iii) ten days after being sent to such party by

         Collateral Agent to be forwarded to such Lender at its address or
         facsimile number specified in or pursuant to Section 10.01 of the

         notice to the Collateral Agent.

Any party may change its address or facsimile number for purposes of this
Section by giving notice of such change to the Collateral Agent and the Lien
Grantors in the manner specified above.

         SECTION 31. No Implied Waivers; Remedies Not Exclusive. No failure by
the Collateral Agent or any Secured Party to exercise, and no delay in
exercising and no course of dealing with respect to, any right or remedy under
any Security Document shall operate as a waiver thereof; nor shall any single or
partial exercise by the Collateral Agent or any Secured Party of any right or
remedy under any Loan Document preclude any other or further exercise thereof or
the exercise of any other right or remedy. The rights and remedies specified in
the Loan Documents are cumulative and are not exclusive of any other rights or
remedies provided by law.

         SECTION 32. Successors and Assigns. This Agreement is for the benefit
of the Collateral Agent and the Secured Parties. If all or any part of any
Secured

                                       55
<PAGE>

Party's interest in any Secured Obligation is assigned or otherwise transferred,
in accordance, in the case of Revolver Secured Obligations and the Term Secured
Obligations with the terms of the Revolving Credit Agreement or the Term Credit
Agreement, respectively, the transferor's rights hereunder, to the extent
applicable to the obligation so transferred, shall be automatically transferred
with such obligation. This Agreement shall be binding on the Lien Grantors and
their respective successors and assigns.

         SECTION 33. Amendments and Waivers. Neither this Agreement nor any
provision hereof may be waived, amended or modified except pursuant to an
agreement or agreements in writing enter into by the parties hereto, with the
consent of the Required Secured Lenders; provided that no such waiver, amendment
or modification shall (a) unless signed by all of the Lenders, change the number
of Lenders (or the percentage of Revolver Commitments or Term Commitments, or
the aggregate unpaid principal amount of the Revolver Loans or Term Loans) which
shall be required for the Lenders or any of them to take any action under (i)
this Section 33, (ii) any provision of Section 27 specifying the circumstances
under which consent of any or all Lenders is required to release Collateral or
(iii) any other provision of this Agreement, or (b) unless signed by all of the
Lenders who would be adversely affected thereby, change any provision of Section
20, Section 21 or Section 22. No such waiver, amendment or modification shall by
its terms affect the rights of a Secured Party (other than a Lender) hereunder
more adversely than it affects the comparable rights of the Lenders hereunder
(taking into account the relative priorities of the Lenders' Transaction Liens
hereunder), without the consent of such Secured Party.

         SECTION 34. Choice of Law. This Agreement shall be construed in
accordance with and governed by the laws of the State of New York, except as
otherwise required by mandatory provisions of law and except to the extent that
remedies provided by the laws of any jurisdiction other than the State of New
York are governed by the laws of such jurisdiction.

         SECTION 35. Waiver of Jury Trial. EACH PARTY HERETO WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING
TO ANY SECURITY DOCUMENT OR ANY TRANSACTION CONTEMPLATED THEREBY (WHETHER BASED
ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT

                                       56
<PAGE>

IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT
BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

         SECTION 36. Severability. If any provision of any Security Document is
invalid or unenforceable in any jurisdiction, then, to the fullest extent
permitted by law, (i) the other provisions of the Security Documents shall
remain in full force and effect in such jurisdiction and shall be liberally
construed in favor of the Collateral Agent and the Secured Parties in order to
carry out the intentions of the parties thereto as nearly as may be possible and
(ii) the invalidity or unenforceability of such provision in such jurisdiction
shall not affect the validity or enforceability thereof in any other
jurisdiction.

                                       57
<PAGE>

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.
