this Agreement (if applicable).

                           immediately due and payable in accordance with the
                           provisions of the Indenture, except for the

then the Collateral Agent shall promptly, subject to applicable bankruptcy laws,
release the proceeds from the Collateral Account and pay to the Trustee for the
benefit of, and payment to, the Holders of the Notes in accordance with the
provisions of the Indenture. Distributions from the Collateral Account shall be
applied, for the ratable benefit of the Holders, as follows:

                  (x)      first, to any accrued and unpaid interest on the
                           Notes and

                                       8

<PAGE>

                  (y)      second, to the extent available, to the repayment of
                           the remaining Obligations, including the principal
                           amount of the Notes.

         Any surplus of such proceeds held by the Collateral Agent and remaining
after payment in full of all of the Obligations shall be paid over to the
Pledgor.

         (c)      In the event that the Collateral held in the Collateral
Account is less than 100% of the amount sufficient, in the written opinion of
Ernst & Young LLP or another nationally recognized firm of independent public
accountants selected by the Pledgor, to provide for payment in full of the first
eight scheduled interest payments due on the Notes (or, in the event an interest
payment or payments have been made, an amount sufficient to provide for payment
in full of all interest payments remaining, up to and including the eighth
scheduled interest payment), the Pledgor shall deposit cash into the Collateral
Account in the amount of such deficiency.

         (d)      In the event that the Collateral held in the Collateral
Account exceeds 100% of the amount sufficient, in the opinion of Ernst & Young
LLP or another nationally recognized firm of independent public accountants
selected by the Pledgor, to provide for payment in full of the first eight
scheduled interest payments due on the Notes (or, in the event an interest
payment or payments have been made, an amount sufficient to provide for payment
in full of all interest payments remaining, up to and including the eighth
scheduled interest payment), the Collateral Agent shall release to the Pledgor,
at the Pledgor's written request, accompanied by a written opinion prepared by
Ernst & Young LLP or such other nationally recognized firm of independent public
accountants, any such excess Collateral.

         (e)      Upon the release of any Collateral from the Collateral
Account, in accordance with the terms of this Pledge Agreement, the security
interest and lien evidenced by this Pledge Agreement in such released Collateral
will automatically terminate and be of no further force and effect; provided
that the foregoing shall not affect the security interest and lien on any
Collateral not so released.

         (f)      Except as expressly provided in this Section 6, nothing
contained in this Pledge Agreement shall (i) afford the Pledgor any right to
issue entitlement orders with respect to any security entitlement to the Pledged
Securities or Collateral Investments or any securities account in which any such
security entitlement may be carried, or otherwise afford the Pledgor control of
any such security entitlement or (ii) otherwise give rise to any rights of the
Pledgor with respect to the Collateral Investments, any security entitlement
thereto or any securities account in which any such security entitlement may be
carried, other than the Pledgor's rights under this Pledge Agreement as the
beneficial owner of Collateral pledged to and subject to the exclusive dominion
and control (including, without limitation, securities control) of the
Collateral Agent in its capacity as such (and not as a securities intermediary).
The Pledgor acknowledges, confirms and agrees that the Collateral Agent holds a
first priority perfected security interest, lien and security entitlement to the
Collateral Investments solely as collateral agent for the Trustee and the
Holders and not as a securities intermediary for the Pledgor.

         SECTION 7. REPRESENTATIONS AND WARRANTIES. The Pledgor hereby
represents and warrants, as of the date hereof, that:

                                       9

<PAGE>

         (a)      The execution and delivery by the Pledgor of, and the
performance by the Pledgor of its obligations under, this Pledge Agreement will
not contravene any provision of applicable law or the certificate of
incorporation, bylaws or equivalent organizational instruments of the Pledgor or
any material agreement or other material instrument binding upon the Pledgor or
any of its subsidiaries or any judgment, order or decree of any governmental
body, agency or court having jurisdiction over the Pledgor or any of its
subsidiaries, or result in the creation or imposition of any Lien on any assets
of the Pledgor, except for the lien and security interests granted under this
Pledge Agreement; no consent, approval, authorization or order of, or
qualification with, and no notice to or filing with, any governmental body or
agency or other third party is required (i) for the performance by the Pledgor
of its obligations under this Pledge Agreement, (ii) for the pledge by the
Pledgor of the Collateral pursuant to this Pledge Agreement or for the
execution, delivery or performance of this Agreement by the Pledgor or (iii) for
the perfection or maintenance of the pledge, assignment and security interest
created hereby (including the first priority nature of such pledge, assignment
or security interest), except for the filing of financing and continuation
statements under the Uniform Commercial Code of applicable jurisdictions which
financing statements have been delivered pursuant to Section 3(f) hereof, or
(iv) except for any such consents, approvals, authorizations or orders required
to be obtained by the Collateral Agent (or the Holders) for reasons other than
the consummation of this transaction, for the exercise by the Collateral Agent
of the rights provided for in this Pledge Agreement or the remedies in respect
of the Collateral pursuant to this Pledge Agreement.

         (b)      The Pledgor is the legal and beneficial owner of the
Collateral, free and clear of any Lien or claims of any Person (except for the
lien and security interests granted under this Pledge Agreement). No effective
financing statement or other instrument similar in effect covering all or any
part of the Collateral is on file in any public office other than the financing
statements, if any, to be filed pursuant to this Pledge Agreement.

         (c)      This Pledge Agreement has been duly authorized, validly
executed and delivered by the Pledgor and (assuming the due authorization and
valid execution and delivery of this Pledge Agreement by each of the Trustee and
the Collateral Agent and enforceability of the Pledge Agreement against each of
the Trustee and the Collateral Agent in accordance with its terms) constitutes a
valid and binding agreement of the Pledgor, enforceable against the Pledgor in
accordance with its terms, except as (i) the enforceability hereof may be
limited by bankruptcy, insolvency, fraudulent conveyance, preference,
reorganization, moratorium or similar laws now or hereafter in effect relating
to or affecting the rights or remedies of creditors generally, (ii) the
availability of equitable remedies may be limited by equitable principles of
general applicability and the discretion of the court before which any
proceeding therefor may be brought, (iii) the exculpation provisions and rights
to indemnification hereunder may be limited by U.S. federal and state securities
laws and public policy considerations and (iv) the waiver of rights and defenses
contained in Section 13(b), Section 18.10 and Section 18.14 hereof may be
limited by applicable law.

         (d)      Upon the delivery to the Collateral Agent of the Collateral in
accordance with the terms hereof and the filing of the financing statements
referred to in Section 3(f) hereof, the pledge of and grant of a security
interest in the Collateral securing the payment of the Obligations for the
benefit of the Trustee and the Holders will constitute a valid, first priority,
perfected security interest in such Collateral (except, with respect to
proceeds, only to the extent

                                       10

<PAGE>

permitted by Section 9-315 of the N.Y. Uniform Commercial Code), enforceable as
such against all creditors of the Pledgor and any persons purporting to purchase
any of the Collateral from the Pledgor other than as permitted by the Indenture.
Upon filing of the financing statements described in Section 3(f) hereof, all
filings and other actions necessary or desirable to perfect and protect such
security interest will have been duly taken.

         (e)      There are no legal or governmental proceedings pending or, to
the best of the Pledgor's knowledge, threatened to which the Pledgor or any of
its subsidiaries is a party or to which any of the properties of the Pledgor or
any of its subsidiaries is subject that would materially adversely affect the
power or ability of the Pledgor to perform its obligations under this Pledge
Agreement or to consummate the transactions contemplated hereby.

         (f)      The pledge of the Collateral pursuant to this Pledge Agreement
is not prohibited by law or governmental regulation (including, without
limitation, Regulations T, U and X of the Board of Governors of the Federal
Reserve System) applicable to the Pledgor.

         (g)      No Event of Default exists.

         (h)      The Pledgor is a corporation duly organized and validly
existing under the laws of the State of Delaware. The Pledgor's name as it
appears in official filings in the State of Delaware is FINISAR CORPORATION. The
Pledgor's organizational identification number issued by the State of Delaware
is 3090879.

         SECTION 8. FURTHER ASSURANCES. The Pledgor will, promptly upon the
request by the Collateral Agent (which request the Collateral Agent may submit
at the direction of the Holders of a majority in aggregate principal amount of
the Notes then outstanding), execute and deliver or cause to be executed and
delivered, or use its reasonable best efforts to procure, all assignments,
instruments and other documents, deliver any instruments to the Collateral Agent
and take any other actions that are necessary or desirable to perfect, continue
the perfection of, or protect the first priority of the Collateral Agent's
security interest in and to the Collateral, to protect the Collateral against
the rights, claims or interests of third persons (other than any such rights,
claims or interests created by or arising through the Collateral Agent) or to
effect the purposes of this Pledge Agreement. Without limiting the generality of
the foregoing, the Pledgor will, if any Collateral shall be evidenced by a
promissory note or other instrument, deliver to the Collateral Agent in pledge
hereunder such note or instrument duly indorsed and accompanied by duly executed
instruments of transfer or assignment; and execute and file such financing or
continuation statements, or amendments thereto, and such other instruments or
notices, as may be necessary, or as the Collateral Agent may reasonably request,
in order to perfect and preserve the pledge, assignment and first priority
perfected security interest granted or purported to be granted hereby. The
Pledgor will promptly pay all costs incurred in connection with any of the
foregoing within 45 days of receipt of an invoice therefor. The Pledgor also
agrees, whether or not requested by the Collateral Agent, to use its reasonable
best efforts to perfect or continue the perfection of, or to protect the first
priority of, the Collateral Agent's security interest in and to the Collateral,
and to protect the Collateral against the rights, claims or interests of third
persons (other than any such rights, claims or interests created by or arising
through the Collateral Agent).

         SECTION 9. COVENANTS. The Pledgor covenants and agrees with the
Collateral Agent, Trustee and the Holders that from and after the date of this
Pledge Agreement until the Termination Date:

         (a)      it will not (i) (and will not purport to) sell or otherwise
dispose of, or grant any option or warrant with respect to, any of the
Collateral nor (ii) create or permit to exist any Lien upon or with respect to
any of the Collateral (except for the liens and security interests granted under
this Pledge Agreement and any Lien created by or arising through the Collateral
Agent) and at all times will be the sole beneficial owner of the Collateral;

         (b)      it will not (i) enter into any agreement or understanding that
restricts or inhibits or purports to restrict or inhibit the Trustee's or the
Collateral Agent's rights or remedies hereunder, including, without limitation,
the Collateral Agent's right to sell or otherwise dispose of the Collateral or
(ii) fail to pay or discharge any tax, assessment or levy of any nature with
respect to its beneficial interest in the Collateral not later than three
Business Days prior to the date of any proposed sale under any judgment, writ or
warrant of attachment with respect to the Collateral;

         (c)      it will maintain its jurisdiction of organization in the State
of Delaware, or upon 30 days' prior written notice to the Collateral Agent, in
another jurisdiction where all actions required by Sections 3(f) and 8 have been
taken with respect to the Collateral; and

         (d)      it will not, and acknowledges that it is not authorized to,
file any financing statement or amendment or termination statement with respect
to any financing statement in favor of the Collateral Agent without the prior
written consent of Collateral Agent and agrees that it will not do so without
the prior written consent of Collateral Agent, subject to the Pledgor's rights
under Section 9-509(d)(2) of the N.Y. Uniform Commercial Code.

         SECTION 10. POWER OF ATTORNEY; AGENT MAY PERFORM.

         (a)      Subject to the terms of this Pledge Agreement, the Pledgor
hereby appoints and constitutes the Collateral Agent as the Pledgor's
attorney-in-fact (with full power of substitution) to exercise to the fullest
extent permitted by law all of the following powers upon and at any time after
the occurrence and during the continuance of an Event of Default:

                  (i)      collection of proceeds of any Collateral;

                  (ii)     conveyance of any item of Collateral to any purchaser
                           thereof;

                  (iii)    giving of any notices or recording of any Liens
                           hereof; and

                  (iv)     paying or discharging taxes or Liens levied or placed
                           upon the Collateral, the legality or validity thereof
                           and the amounts necessary to discharge the same to be
                           determined by the Collateral Agent in its sole
                           reasonable discretion, and such payments made by the
                           Collateral Agent to become part of the Obligations
                           secured hereby, due and payable immediately upon
                           demand. The Collateral Agent's authority under this
                           Section 10 shall include, without limitation, the
                           authority to endorse and negotiate any checks or
                           instruments representing proceeds of Collateral in
                           the name of

                                       12

<PAGE>

                           the Pledgor, execute and give receipt for any
                           certificate of ownership or any document constituting
                           Collateral, transfer title to any item of Collateral,
                           sign the Pledgor's name on all financing statements
                           (to the extent permitted by applicable law) or any
                           other documents necessary or appropriate to preserve,
                           protect or perfect the security interest in the
                           Collateral and to file the same, prepare, file and
                           sign the Pledgor's name on any notice of Lien (to the
                           extent permitted by applicable law), and to take any
                           other actions arising from or necessarily incident to
                           the powers granted to the Trustee or the Collateral
                           Agent in this Pledge Agreement. This power of
                           attorney is coupled with an interest and is
                           irrevocable by the Pledgor.

         (b)      If the Pledgor fails to perform any agreement contained
herein, the Collateral Agent may, but is not obligated to, after providing to
the Pledgor notice of such failure and five Business Days to effect such
performance, itself perform, or cause performance of, such agreement, and the
expenses of the Collateral Agent incurred in connection therewith shall be
payable by the Pledgor under Section 14.

         SECTION 11. NO ASSUMPTION OF DUTIES; REASONABLE CARE. The rights and
powers granted to the Collateral Agent hereunder are being granted in order to
preserve and protect the security interest of the Collateral Agent for the
benefit of the Trustee and the Holders in and to the Collateral granted hereby
and shall not be interpreted to, and shall not impose any duties on, the
Collateral Agent in connection therewith other than those expressly provided
herein or imposed under applicable law. Except as provided by applicable law or
by the Indenture, the Collateral Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Collateral in its
possession if the Collateral is accorded treatment substantially equal to that
which the Collateral Agent accords similar property held by the Collateral Agent
for similar accounts, it being understood that the Collateral Agent in its
capacity as such

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

         (b)      shall not have any responsibility for

                  (i)      ascertaining or taking action with respect to calls,
                           conversions, exchanges, maturities or other matters
                           relative to any Collateral, whether or not the
                           Collateral Agent has or is deemed to have knowledge
                           of such matters,

                  (ii)     taking any necessary steps for the existence,
                           enforceability or perfection of any security interest
                           of the Collateral Agent or to preserve rights against
                           any parties with respect to any Collateral or

                  (iii)    except as otherwise set forth in Section 5, investing
                           or reinvesting any of the Collateral, provided,
                           however, that in the case of clause (a) and clause
                           (b) of this sentence, nothing contained in this
                           Pledge Agreement shall

                                       13

<PAGE>

                           relieve the Collateral Agent of any responsibilities
                           as a securities intermediary under applicable law.

         In no event shall the Collateral Agent be liable for the existence,
validity, enforceability or perfection of any security interest of the
Collateral Agent, or for special indirect or consequential damages or lost
profits or loss of business, arising in connection with this Agreement.

         SECTION 12. INDEMNITY. The Pledgor shall fully indemnify, hold harmless
and defend the Collateral Agent and its directors and officers from and against
any and all claims, losses, actions, obligations, liabilities and expenses,
including reasonable defense costs, reasonable investigative fees and costs, and
reasonable legal fees, expenses, and damages arising from the Collateral Agent's
appointment and performance as Collateral Agent under this Pledge Agreement,
except to the extent that such claim, action, obligation, liability or expense
is directly caused by the bad faith, gross negligence or willful misconduct of
such indemnified person. The provisions of this Section 12 shall survive
termination of this Pledge Agreement and the resignation and removal of the
Collateral Agent.

         SECTION 13. REMEDIES UPON EVENT OF DEFAULT. Subject to Section 6(b), if
any Event of Default under the Indenture shall have occurred and be continuing
and the Notes shall have been accelerated in accordance with the provisions of
the Indenture:

         (a)      The Trustee, the Collateral Agent and the Holders shall have,
in addition to all other rights given by law or by this Pledge Agreement or the
Indenture, all of the rights and remedies with respect to the Collateral of a
secured party upon default under the N.Y. Uniform Commercial Code (whether or
not the N.Y. Uniform Commercial Code applies to the affected Collateral) at that
time. In addition, with respect to any Collateral that shall then be in or shall
thereafter come into the possession or custody of the Collateral Agent, the
Collateral Agent may and, at the written direction of the Trustee or the Holders
of a majority in aggregate principal amount of the Notes then outstanding, shall
appoint a broker or other expert to sell or cause the same to be sold at any
broker's board or at public or private sale, in one or more sales or lots, at
such price or prices such broker or other expert may deem commercially
reasonable, for cash or on credit or for future delivery, without assumption of
any credit risk. The purchaser of any or all Collateral so sold shall thereafter
hold the same absolutely, free from any claim, encumbrance or right of any kind
whatsoever created by or through the Pledgor. Unless any of the Collateral
threatens, in the reasonable judgment of the Collateral Agent, to decline
speedily in value, the Collateral Agent will give the Pledgor reasonable notice
of the time and place of any public sale thereof, or of the time after which any
private sale or other intended disposition is to be made. Any sale of the
Collateral conducted in conformity with reasonable commercial practices of
banks, insurance companies, commercial finance companies, or other financial
institutions disposing of property similar to the Collateral shall be deemed to
be commercially reasonable. Any requirements of reasonable notice shall be met
if notice of the time and place of any public sale or the time after which any
private sale is to be made is given to the Pledgor as provided in Section 17.1
hereof at least ten (10) days before the time of the sale or disposition. The
Collateral Agent or any Holder may, in its own name or in the name of a designee
or nominee, buy any of the Collateral at any public sale and, if permitted by
applicable law, at any private sale. The Collateral Agent shall not be obligated
to make any sale of Collateral regardless of notice of sale

                                       14

<PAGE>

having been given. The Collateral Agent may adjourn any public or private sale
from time to time by announcement at the time and place fixed therefor, and such
sale may, without further notice, be made at the time and place to which it was
so adjourned. All expenses (including court costs and reasonable attorneys'
fees, expenses and disbursements) of, or incident to, the enforcement of any of
the provisions hereof shall be recoverable from the proceeds of the sale or
other disposition of the Collateral.

         (b)      The Pledgor further agrees to use its reasonable best efforts
to do or cause to be done all such other acts as may be necessary to make such
sale or sales of all or any portion of the Collateral pursuant to this Section
13 valid and binding and in compliance with any and all other applicable
requirements of law. The Pledgor further agrees that a breach of any of the
covenants contained in this Section 13 will cause irreparable injury to the
Trustee and the Holders, that the Trustee and the Holders have no adequate
remedy at law in respect of such breach and, as a consequence, that each and
every covenant contained in this Section 13 shall be specifically enforceable
against the Pledgor, and the Pledgor hereby waives and agrees not to assert any
defenses against an action for specific performance of such covenants except for
a defense that no Event of Default has occurred.

         (c)      All cash proceeds received by the Collateral Agent in respect
of any sale of, collection from, or other realization upon all or any part of
the Collateral may, in the discretion of the Collateral Agent, be held by the
Collateral Agent as collateral for, and/or then or at any time thereafter
applied (after payment of any amounts payable to the Collateral Agent or the
Trustee pursuant to Section 14) by the Collateral Agent for the ratable benefit
of the Holders first against any accrued and unpaid interest on the Notes and
thereafter against the remaining Obligations. Any surplus of such cash or cash
proceeds held by the Collateral Agent and remaining after payment in full of all
of the Obligations shall be paid over to the Pledgor.

         (d)      The Collateral Agent may, but is not obligated to, exercise
any and all rights and remedies of the Pledgor in respect of the Collateral.

         (e)      Subject to and in accordance with the terms of this Pledge
Agreement, all payments received by the Pledgor in respect of the Collateral
shall be received in trust for the benefit of the Collateral Agent, shall be
segregated from other funds of the Pledgor and shall be forthwith paid over to
the Collateral Agent in the same form as so received (with any necessary
indorsement).

         (f)      The Collateral Agent may, without notice to the Pledgor except
as required by law and at any time or from time to time, charge, set-off and
otherwise apply all or any part of the Obligations against the Collateral
Account or any part thereof.

         (g)      The Pledgor shall cease to be entitled to direct the
investment of amounts held in the Collateral Account under Section 5 hereof and
the Collateral Agent shall not accept any direction from the Pledgor to invest
amounts held in the Collateral Account.

         SECTION 14. FEES AND EXPENSES. Pledgor agrees to pay to Collateral
Agent the fees as may be agreed upon from time to time in writing. The Pledgor
will upon demand pay to the Trustee and the Collateral Agent the amount of any
and all expenses, including, without

                                       15

<PAGE>

limitation, the reasonable fees, expenses and disbursements of counsel, experts
and agents retained by the Trustee and the Collateral Agent, that the Trustee
and the Collateral Agent may incur in connection with

         (a)      the review, negotiation and administration of this Pledge
Agreement,

         (b)      the custody or preservation of, or the sale of, collection
from, or other realization upon, any of the Collateral,

         (c)      the exercise or enforcement of any of the rights of the
Collateral Agent, the Trustee and the Holders hereunder or

         (d)      the failure by the Pledgor to perform or observe any of the
provisions hereof.

         SECTION 15. SECURITY INTEREST ABSOLUTE. All rights of the Collateral
Agent, the Trustee and the Holders and security interests hereunder, and all
obligations of the Pledgor hereunder, shall be absolute and unconditional
irrespective of:

         (a)      any lack of validity or enforceability of the Indenture or any
other agreement or instrument relating thereto;

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

         (c)      any exchange, surrender, release or non-perfection of any
Liens on any other collateral for all or any of the Obligations;

         18.3     SEVERABILITY. The provisions of this Pledge Agreement are
severable, and if any clause or provision shall be held invalid, illegal or
unenforceable in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect in that jurisdiction only such clause or
provision, or part thereof, and shall not in any manner affect such clause or
provision in any other jurisdiction or any other clause or provision of this
Pledge Agreement in any jurisdiction.

         18.4     HEADINGS. The headings in this Pledge Agreement have been
inserted for convenience of reference only, are not to be considered a part
hereof and shall in no way modify or restrict any of the terms or provisions
hereof.

         18.5     COUNTERPART ORIGINALS. This Pledge Agreement may be signed in
two or more counterparts, each of which shall be deemed an original, but all of
which shall together constitute one and the same agreement.

         18.6     BENEFITS OF PLEDGE AGREEMENT. Nothing in this Pledge
Agreement, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, and the Holders, any benefit or any legal

any provision of this Pledge Agreement and any consent to any departure by the

breach of any of the terms and conditions hereof. Failure of the Trustee, the
Pledgor, the Collateral Agent or any Holder to exercise, or delay in exercising,

exercise thereof or the exercise of any other right, power or privilege. A
waiver by the Trustee, the Pledgor, the Collateral Agent or any Holder of any
right or remedy hereunder on any one occasion shall not be construed as a bar to
any right or remedy that the Trustee, the Pledgor, the Collateral Agent or such
Holder would otherwise have on any future occasion. The rights and remedies
herein provided are cumulative, may be exercised singly or concurrently and are
not exclusive of any rights or remedies provided by law.

Collateral Agent hereunder, to the benefit of the Trustee, the Collateral Agent,
the Pledgor, the Holders and their respective successors, transferees and
assigns.

                                       19

<PAGE>

         (b)      Upon the Termination Date, the pledge, assignment and security
interest granted hereby shall terminate and all rights to the Collateral shall
revert to the Pledgor. At such time, the Collateral Agent shall, in accordance
with the Pledgor's instructions, promptly reassign and redeliver to the Pledgor
all of the Collateral hereunder that has not been sold, disposed of, retained or
applied by the Collateral Agent in accordance with the terms of this Pledge
Agreement and the Indenture and execute and deliver to the Pledgor such
documents as the Pledgor shall reasonably request to evidence such termination.
Such reassignment and redelivery shall be without warranty by or recourse to the
Collateral Agent or the Trustee in its capacity as such, except as to the
absence of any Liens on the Collateral created by or arising through the
Collateral Agent or the Trustee, and shall be at the reasonable expense of the
Pledgor.

might otherwise be entitled, except as otherwise expressly provided herein or in
the Indenture.

         18.11    AUTHORITY OF THE COLLATERAL AGENT.

         (a)      The Collateral Agent shall have and be entitled to exercise
all powers hereunder that are specifically granted to the Collateral Agent by
the terms hereof, together with such powers as are reasonably incident thereto.
The Collateral Agent may perform any of its duties hereunder or in connection
with the Collateral by or through agents or attorneys, shall not be responsible
for any misconduct or negligence on the part of any agent or attorney appointed
with due care by it hereunder and shall be entitled to retain counsel and to act
in reliance upon the advice of counsel concerning all such matters. Except as
otherwise expressly provided in this Pledge Agreement or the Indenture, neither
the Collateral Agent nor any director, officer, employee, attorney or agent of
the Collateral Agent shall be liable to the Pledgor for any action taken or
omitted to be taken by the Collateral Agent, in its capacity as Collateral
Agent, hereunder, except for its own bad faith, gross negligence or willful
misconduct, and the Collateral Agent shall not be responsible for the validity,
effectiveness or sufficiency hereof or of any document or security furnished
pursuant hereto. The Collateral Agent and its directors, officers, employees,

Indenture and by such other agreements with respect thereto as may exist from
time to time among them, but, as between the Collateral Agent and the Pledgor,
the Collateral Agent shall be conclusively presumed to be acting as agent for
the Trustee and the Holders with full and valid authority so to act or refrain
from acting, and the Pledgor shall not be obligated or entitled to make any
inquiry respecting such authority.

         18.12    FINAL EXPRESSION. This Pledge Agreement, together with the
Indenture and any other agreement executed in connection herewith, is intended
by the parties as a final expression of this Pledge Agreement and is intended as
a complete and exclusive statement of the terms and conditions thereof.

hereunder other than those rights granted to individual Holders pursuant to
Sections 6.05, 6.06 and 6.07 of the Indenture; provided that nothing in this
subsection shall limit any rights granted to the Trustee under the Notes or the
