                                    Exhibit A

         The China JV proposes to construct a new manufacturing facility in
Leshan, China consisting of a multi-phased submicron capable wafer fab (the "New
Leshan Facility"). The New Leshan Facility will be constructed on real property
currently owned by the China JV that is adjacent to the China JV's existing
facilities. The approximate cost of the first phase of the construction of the
New Leshan Facility, which is currently scheduled to begin in August of 2002, is
approximately $20 million. The cost and precise timing of future phases will
depend on market conditions, but it is currently expected that future phases
would commence in late 2003 and that the New Leshan Facility would be completed
in 2006 at an aggregate cost of approximately $350 million.

         The following amendments to the Leshan JV agreement, among others, may
be required in order to construct the New Leshan Facility:

         -        revise the scope of operations of the Leshan JV to include New
                  Leshan Facility;

         -        increase the total authorized investment by $350 million; and

         -        increase the registered capital by $70 million.

         Any investment in the Leshan JV by Holdings, the Borrower or any other
Subsidiary remains subject to the terms of the Credit Agreement.

of grant, attachment or perfection of any Liens granted to the Trustee or the
Noteholders on the Common Collateral or of any Liens granted to the Credit Agent
or the Senior Lenders on the Common Collateral and notwithstanding any provision
of the UCC, or any applicable law or the Noteholder Documents or the Senior
Lender Documents or any other circumstance whatsoever, the Trustee, on behalf of
itself and the Noteholders, hereby agrees that: (a) any Lien on the Common
Collateral securing any Senior Lender Claims now or hereafter held by or on
behalf of the Credit Agent or any Senior Lenders or any agent or trustee
therefor shall be senior in all respects and prior to any Lien on the Common
Collateral securing any of the Noteholder Claims; and (b) any Lien on the Common
Collateral now or hereafter held by or on behalf of the Trustee or any
Noteholders or any agent or trustee therefor regardless of how acquired, whether
by grant, statute, operation of law, subrogation or otherwise, shall be junior
and subordinate in all respects to all Liens on the Common Collateral securing
any Senior Lender Claims. All Liens on the Common Collateral securing any Senior
Lender Claims shall be and remain senior in all respects and prior to all Liens
on the Common Collateral securing any Noteholder Claims for all purposes,
whether or not such Liens securing any Senior Lender Claims are subordinated to
any Lien securing any other obligation of either Company, any other Grantor or
any other Person.

                  2.2 Prohibition on Contesting Liens. Each of the Trustee, for
itself and on behalf of each Noteholder, and the Credit Agent, for itself and on
behalf of each Senior Lender, agrees that it shall not (and hereby waives any
right to) contest or support any other Person in contesting, in any proceeding
(including any Insolvency or Liquidation Proceeding), the priority, validity or
enforceability of a Lien held by or on behalf of any of the Senior Lenders in
the Senior Lender Collateral or by or on behalf of any of the Noteholders in the
Common Collateral, as the case may be; provided that nothing in this Agreement
shall be construed to prevent or impair the rights of the Credit Agent or any
Senior Lender to enforce this Agreement, including the priority of the Liens
securing the Senior Lender Claims as provided in Section 2.1.

                  2.3 No New Liens. So long as the Discharge of Senior Lender
Claims has not occurred, (a) the parties hereto agree that, after the date
hereof, if the Trustee shall hold any Lien on any assets of either Company or
any other Grantor securing any Noteholder Claims that are not also subject to
the first-priority Lien of the Credit Agent under the Senior Lender Documents,
the Trustee, upon demand by the Credit Agent or the Companies, will either
release such Lien or assign it to the Credit Agent as security for the Senior
Lender Claims, and (b) each of the Companies agrees that it will not, and will
not permit any Subsidiary to, grant or permit to exist any Lien on any assets of
either Company or any of its Subsidiaries to secure any Noteholder Claim unless
a perfected prior Lien on the same assets has been granted to secure the Senior
Lender Claims.

                  SECTION 3. ENFORCEMENT.

                  3.1 Exercise of Remedies.

                  (a) So long as the Discharge of Senior Lender Claims has not
occurred, whether or not any Insolvency or Liquidation Proceeding has been
commenced by or against either

                                       8
<PAGE>
Company or any other Grantor, (i) the Trustee and the Noteholders will not
exercise or seek to exercise any rights or remedies (including set-off) with
respect to any Common Collateral, institute any action or proceeding with
respect to such rights or remedies (including any action of foreclosure),
contest, protest or object to any foreclosure proceeding or action brought by
the Credit Agent or any Senior Lender, the exercise of any right under any
lockbox agreement, landlord waiver or bailee's letter or similar agreement or
arrangement to which the Trustee or any Noteholder is a party, or any other
exercise by any such party, of any rights and remedies relating to the Common
Collateral under the Senior Lender Documents or otherwise, or object to the
forbearance by the Senior Lenders from bringing or pursuing any foreclosure
proceeding or action or any other exercise of any rights or remedies relating to
the Common Collateral and (ii) the Credit Agent and the Senior Lenders shall
have the exclusive right to enforce rights, exercise remedies (including set-off
and the right to credit bid their debt) and make determinations regarding the
release, disposition, or restrictions with respect to the Common Collateral
without any consultation with or the consent of the Trustee or any Noteholder;
provided, that (A) in any Insolvency or Liquidation Proceeding commenced by or
against either Company or any Grantor, the Trustee may file a claim or statement
of interest with respect to the Noteholder Claims, and (B) the Trustee may take
any action (not adverse to the prior Liens on the Common Collateral securing the
Senior Lender Claims, or the rights of the Credit Agent or the Senior Lenders to
exercise remedies in respect thereof) in order to preserve or protect its Lien
on the Common Collateral. In exercising rights and remedies with respect to the
Common Collateral, the Credit Agent and the Senior Lenders may enforce the
provisions of the Senior Lender Documents and exercise remedies thereunder, all
in such order and in such manner as they may determine in the exercise of their
sole discretion. Such exercise and enforcement shall include the rights of an
agent appointed by them to sell or otherwise dispose of Common Collateral upon
foreclosure, to incur expenses in connection with such sale or disposition, and
to exercise all the rights and remedies of a secured lender under the Uniform
Commercial Code of any applicable jurisdiction and of a secured creditor under
Bankruptcy Laws of any applicable jurisdiction.

                  (b) The Trustee, on behalf of itself and the Noteholders,
agrees that it will not take or receive any Common Collateral or any proceeds of
Common Collateral in connection with the exercise of any right or remedy
(including set-off) with respect to any Common Collateral, unless and until the
Discharge of Senior Lender Claims has occurred. Without limiting the generality
of the foregoing, unless and until the Discharge of Senior Lender Claims has
occurred, except as expressly provided in the proviso in clause (ii) of Section
3.1(a) above, the sole right of the Trustee and the Noteholders with respect to
the Common Collateral is to hold a Lien on the Common Collateral pursuant to the
Noteholder Documents for the period and to the extent granted therein and to
receive a share of the proceeds thereof, if any, after the Discharge of the
Senior Lender Claims has occurred.

                  (c) Subject to the proviso in clause (ii) of Section 3.1(a)
above, (i) the Trustee, for itself or on behalf of the Noteholders, agrees that
the Trustee and the Noteholders will not take any action that would hinder any
exercise of remedies undertaken by the Credit Agent under the Senior Loan
Documents, including any sale, lease, exchange, transfer or other disposition of
the Common Collateral, whether by foreclosure or otherwise, and (ii) the
Trustee, for itself and on behalf of the Noteholders, hereby waives any and all
rights it or the Noteholders may have as a junior lien creditor or otherwise to
object to the manner in which the Credit Agent or the Senior

                                       9
<PAGE>
Lenders seek to enforce or collect the Senior Lender Claims or the Liens granted
in any of the Senior Lender Collateral, regardless of whether any action or
failure to act by or on behalf of the Credit Agent or Senior Lenders is adverse
to the interest of the Noteholders.

                  (d) The Trustee hereby acknowledges and agrees that no
covenant, agreement or restriction contained in any Noteholder Document shall be
deemed to restrict in any way the rights and remedies of the Credit Agent or the
Senior Lenders with respect to the Common Collateral as set forth in this
Agreement and the Senior Lender Documents.

                  3.2 Cooperation. Subject to the proviso in clause (ii) of
Section 3.1(a) above, the Trustee, on behalf of itself and the Noteholders,
agrees that, unless and until the Discharge of Senior Lender Claims has
occurred, it will not commence, or join with any Person (other than the Senior
Lenders and the Credit Agent upon the request thereof) in commencing, any
enforcement, collection, execution, levy or foreclosure action or proceeding
with respect to any Lien held by it under any of the Noteholder Documents or
otherwise.

                  SECTION 4. PAYMENTS.

                  4.1 Application of Proceeds. As long as the Discharge of
Senior Lender Claims has not occurred, the Common Collateral or proceeds thereof
received in connection with the sale or other disposition of, or collection on,
such Common Collateral upon the exercise of remedies, shall be applied by the
Credit Agent to the Senior Lender Claims in such order as specified in the
relevant Senior Lender Documents until the Discharge of Senior Lender Claims has
occurred. Upon the Discharge of the Senior Lender Claims, the Credit Agent shall
deliver to the Trustee any proceeds of Common Collateral held by it in the same
form as received, with any necessary endorsements or as a court of competent
jurisdiction may otherwise direct to be applied by the Trustee to the Noteholder
Claims in such order as specified in the relevant Noteholder Documents.

                  4.2 Payments Over. Any Common Collateral or proceeds thereof
received by the Trustee or any Noteholder in connection with the exercise of any
right or remedy (including set-off) relating to the Common Collateral in
contravention of this Agreement shall be segregated and held in trust and
forthwith paid over to the Credit Agent for the benefit of the Senior Lenders in
the same form as received, with any necessary endorsements or as a court of
competent jurisdiction may otherwise direct. The Credit Agent is hereby
authorized to make any such endorsements as agent for the Trustee or any such
Noteholder. This authorization is coupled with an interest and is irrevocable.

                  SECTION 5. OTHER AGREEMENTS.

                  5.1 Releases.

                  (a) If in connection with:

                            (i) the exercise of the Credit Agent's remedies in
         respect of the Common Collateral provided for in Section 3.1, including
         any sale, lease, exchange, transfer or other disposition of any such
         Common Collateral;

                                       10
<PAGE>
                            (ii) any sale, lease, exchange, transfer or other
         disposition of any Common Collateral permitted under the terms of the
         Senior Credit Agreement (whether or not an event of default thereunder,
         and as defined therein, has occurred and is continuing) and permitted
         or not prohibited under Section 4.06 of the Indenture (Asset Sales); or

                            (iii) any agreement between the Credit Agent and
         either Company or any other Grantor to release the Credit Agent's Lien
         on any portion of the Common Collateral or to release any Grantor from
         its obligations under its guaranty of the Senior Lender Claims,
         provided that after giving effect to the release, Obligations secured
         by the first priority Liens on the remaining Common Collateral remain
         outstanding;

the Credit Agent, for itself or on behalf of any of the Senior Lenders, releases
any of its Liens on any part of the Common Collateral (or any Grantor from its
obligations under its guaranty of the Senior Lender Claims), the Liens, if any,
of the Trustee, for itself or for the benefit of the Noteholders, on such Common
Collateral (and the obligations of such Grantor under its guaranty of the
Noteholder Claims) shall be automatically, unconditionally and simultaneously
released and the Trustee, for itself or on behalf of any such Noteholder,
promptly shall execute and deliver to the Credit Agent or such Grantor such
termination statements, releases and other documents as the Credit Agent or such
Grantor may request to effectively confirm such release; provided that a Grantor
shall not be released from its guaranty of the Noteholder Claims pursuant to
this Section if such Grantor will remain liable under a guaranty in respect of
the Senior Subordinated Notes (as defined in the Indenture).

                  (b) The Trustee, for itself and on behalf of the Noteholders,
hereby irrevocably constitutes and appoints the Credit Agent and any officer or
agent of the Credit Agent, with full power of substitution, as its true and
lawful attorney-in-fact with full irrevocable power and authority in the place
and stead of the Trustee or such holder or in the Credit Agent's own name, from
time to time in the Credit Agent's discretion, for the purpose of carrying out
the terms of this Section 5.1, to take any and all appropriate action and to
execute any and all documents and instruments which may be necessary or
desirable to accomplish the purposes of this Section 5.1, including any
termination statements, endorsements or other instruments of transfer or
release.

                  5.2 Insurance. Unless and until the Discharge of Senior Lender
Claims has occurred, the Credit Agent and the Senior Lenders shall have the sole
and exclusive right, subject to the rights of the Grantors under the Senior
Lender Documents, to adjust settlement for any insurance policy covering the
Common Collateral in the event of any loss thereunder and to approve any award
granted in any condemnation or similar proceeding affecting the Common
Collateral. Unless and until the Discharge of Senior Lender Claims has occurred,
all proceeds of any such policy and any such award if in respect to the Common
Collateral shall be paid to the Credit Agent for the benefit of the Senior
Lenders to the extent required under the Senior Lender Documents and thereafter
to the Trustee for the benefit of the Noteholders to the extent required under
the applicable Noteholder Documents and then to the owner of the subject
property or as a court of competent jurisdiction may otherwise direct. If the
Trustee or any Noteholder shall, at any time, receive any proceeds of any such
insurance policy or any such award in contravention of this Agreement, it shall
pay such proceeds over to the Credit Agent in accordance with the terms of
Section 4.2.

                                       11
<PAGE>
                  5.3 Amendments to Noteholder Collateral Documents.

                  (a) Without the prior written consent of the Credit Agent and
the Required Lenders, no Noteholder Collateral Document may be amended,
supplemented or otherwise modified or entered into to the extent such amendment,
supplement or modification, or the terms of any new Noteholder Collateral
Document, would be prohibited by or inconsistent with any of the terms of the
Senior Lender Documents. The Trustee agrees that each Noteholder Collateral
Document shall include the following language (or language to similar effect
approved by the Credit Agent):

                  "Notwithstanding anything herein to the contrary, the lien and
                  security interest granted to the Trustee pursuant to this
                  Agreement and the exercise of any right or remedy by the
                  Trustee hereunder are subject to the provisions of the
                  Intercreditor Agreement, dated as of May 6, 2002 (as amended,
                  supplemented or otherwise modified from time to time, the
                  "Intercreditor Agreement"), among ON Semiconductor
                  Corporation, Semiconductor Components Industries, LLC,
                  JPMorgan Chase Bank, as Credit Agent, and Wells Fargo Bank
                  Minnesota, National Association, as Trustee. In the event of
                  any conflict between the terms of the Intercreditor Agreement
                  and this Agreement, the terms of the Intercreditor Agreement
                  shall govern."

In addition, the Trustee agrees that each Noteholder Mortgage covering any
Common Collateral shall contain such other language as the Credit Agent may
reasonably request to reflect the subordination of such Noteholder Mortgage to
the Senior Collateral Document covering such Common Collateral.

                  (b) In the event the Credit Agent or the Senior Lenders enter
into any amendment, waiver or consent in respect of any of the Senior Collateral
Documents for the purpose of adding to, or deleting from, or waiving or
consenting to any departures from any provisions of, any Senior Collateral
Document or changing in any manner the rights of the Credit Agent, the Senior
Lenders, either Company or any other Grantor thereunder, then such amendment,
waiver or consent shall apply automatically to any comparable provision of the
Indenture and the Comparable Noteholder Collateral Document without the consent
of the Trustee or the Noteholders and without any action by the Trustee, either
Company or any other Grantor, provided, that (A) no such amendment, waiver or
consent shall have the effect of removing assets subject to the Lien of the
Noteholder Collateral Documents, except to the extent that a release of such
Lien is permitted by Section 5.1 and (B) notice of such amendment, waiver or
consent shall have been given to the Trustee.

                  5.4 Rights As Unsecured Creditors. Notwithstanding anything to
the contrary in this Agreement, the Trustee and the Noteholders may exercise
rights and remedies as an unsecured creditor against either Company or any
Subsidiary that has guaranteed the Noteholder Claims in accordance with the
terms of the Noteholder Documents and applicable law. Nothing in this Agreement
shall prohibit the receipt by the Trustee or any Noteholders of the required
payments of interest and principal so long as such receipt is not the direct or
indirect result of the exercise by the Trustee or any Noteholder of rights or
remedies as a secured creditor or enforcement in contravention of this Agreement
of any Lien held by any of them. In the event the Trustee or any Noteholder
becomes a judgment lien creditor in respect of Common Collateral

                                       12
<PAGE>
as a result of its enforcement of its rights as an unsecured creditor, such
judgment lien shall be subordinated to the Liens securing Senior Lender Claims
on the same basis as the other Liens securing the Noteholder Claims are so
subordinated to such Senior Lender Claims under this Agreement. Nothing in this
Agreement impairs or otherwise adversely affects any rights or remedies the
Credit Agent or the Senior Lenders may have with respect to the Senior Lender
Collateral.

                  5.5 Bailee for Perfection.

                  (a) The Credit Agent agrees to hold the Pledged Collateral
that is part of the Common Collateral in its possession or control (or in the
possession or control of its agents or bailees) as bailee for the Trustee and
any assignee solely for the purpose of perfecting the security interest granted
in such Pledged Collateral pursuant to the Noteholder Pledge Agreement, subject
to the terms and conditions of this Section 5.5.

                  (b) Until the Discharge of Senior Lender Claims has occurred,
the Credit Agent shall be entitled to deal with the Pledged Collateral in
accordance with the terms of the Senior Lender Documents as if the Liens of the
Trustee under the Noteholder Collateral Documents did not exist. The rights of
the Trustee shall at all times be subject to the terms of this Agreement and to
the Credit Agent's rights under the Senior Lender Documents.

                  (c) The Credit Agent shall have no obligation whatsoever to
the Trustee or any Noteholder to assure that the Pledged Collateral is genuine
or owned by any of the Grantors or to preserve rights or benefits of any Person
except as expressly set forth in this Section 5.5. The duties or
responsibilities of the Credit Agent under this Section 5.5 shall be limited
solely to holding the Pledged Collateral as bailee for the Trustee for purposes
of perfecting the Lien held by the Trustee.

                  (d) The Credit Agent shall not have by reason of the
Noteholder Collateral Documents or this Agreement or any other document a
fiduciary relationship in respect of the Trustee or any Noteholder.

                  (e) Upon the Discharge of Senior Lender Claims, the Credit
Agent shall deliver to the Trustee the remaining Pledged Collateral (if any)
together with any necessary endorsements (or otherwise allow the Trustee to
obtain control of such Pledged Collateral) or as a court of competent
jurisdiction may otherwise direct.

                  5.6 When Discharge of Senior Lender Claims Deemed to Not Have
Occurred. If at any time after the Discharge of Senior Lender Claims has
occurred the Companies designate any Future First-Lien Credit Facility to be the
"Senior Credit Agreement" hereunder, then such Discharge of Senior Lender Claims
shall automatically be deemed not to have occurred for all purposes of this
Agreement (other than with respect to any actions taken prior to the date of
such designation as a result of the occurrence of such first Discharge of Senior
Lender Claims), and such Future First-Lien Credit Facility shall automatically
be treated as the Senior Credit Agreement for all purposes of this Agreement,
including for purposes of the Lien priorities and rights in respect of Common
Collateral set forth herein. Upon receipt of notice of such designation
(including the identity of the new Credit Agent), the Trustee shall promptly (i)
enter

                                       13
<PAGE>
into such documents and agreements (including amendments or supplements to this
Agreement) as either Company or such new Credit Agent shall request in order to
provide to the new Credit Agent the rights of the Credit Agent contemplated
hereby and (ii) deliver to the Credit Agent the Pledged Collateral together with
any necessary endorsements (or otherwise allow such Credit Agent to obtain
control of such Pledged Collateral).

                  SECTION 6. INSOLVENCY OR LIQUIDATION PROCEEDINGS.

                  6.1 Financing Issues. If either Company or any other Grantor
shall be subject to any Insolvency or Liquidation Proceeding and the Credit
Agent shall desire to permit the use of cash collateral or to permit either
Company or any other Grantor to obtain financing under Section 363 or Section
364 of Title 11 of the United States Code or any similar Bankruptcy Law ("DIP
Financing"), then the Trustee, on behalf of itself and the Noteholders, agrees
that it will raise no objection to such use of cash collateral or DIP Financing
and will not request adequate protection or any other relief in connection
therewith (except to the extent permitted by Section 6.3) and, to the extent the
Liens securing the Senior Lender Claims are subordinated or pari passu with such
DIP Financing, will subordinate its Liens in the Common Collateral to such DIP
Financing (and all Obligations relating thereto) on the same basis as the other
Liens securing the Noteholder Claims are so subordinated to Senior Lender Claims
under this Agreement.

                  6.2 Relief from the Automatic Stay. Until the Discharge of
Senior Lender Claims has occurred, the Trustee, on behalf of itself and the
Noteholders, agrees that none of them shall seek relief from the automatic stay
or any other stay in any Insolvency or Liquidation Proceeding in respect of the
Common Collateral, without the prior written consent of the Credit Agent and the
Required Lenders.

                  6.3 Adequate Protection. The Trustee, on behalf of itself and
the Noteholders, agrees that none of them shall contest (or support any other
Person contesting) (a) any request by the Credit Agent or the Senior Lenders for
adequate protection or (b) any objection by the Credit Agent or the Senior
Lenders to any motion, relief, action or proceeding based on the Credit Agent or
the Senior Lenders claiming a lack of adequate protection. Notwithstanding the
foregoing contained in this Section 6.3, in any Insolvency or Liquidation
Proceeding, (i) if the Senior Lenders (or any subset thereof) are granted
adequate protection in the form of additional collateral in connection with any
DIP Financing or use of cash collateral under Section 363 or Section 364 of
Title 11 of the United States Code or any similar Bankruptcy Law, then the
Trustee, on behalf of itself or any of the Noteholders, may seek or request
adequate protection in the form of a replacement Lien on such additional
collateral, which Lien is subordinated to the Liens securing the Senior Lender
Claims and such DIP Financing (and all Obligations relating thereto) on the same
basis as the other Liens securing the Noteholder Claims are so subordinated to
the Senior Lender Claims under this Agreement, and (ii) in the event the
Trustee, on behalf of itself and the Noteholders, seeks or requests adequate
protection and such adequate protection is granted in the form of additional
collateral, then the Trustee, on behalf of itself or any of the Noteholders,
agrees that the Credit Agent shall also be granted a senior Lien on such
additional collateral as security for the Senior Lender Claims and any such DIP
Financing and that any Lien on such additional collateral securing the
Noteholder Claims shall be subordinated to the Liens on such collateral securing
the Senior Lender Claims and any such DIP Financing (and all Obligations
relating thereto) and any other Liens granted to the Senior Lenders as adequate

                                       14
<PAGE>
protection on the same basis as the other Liens securing the Noteholder Claims
are so subordinated to such Senior Lender Claims under this Agreement.

                  6.4 No Waiver. Nothing contained herein shall prohibit or in
any way limit the Credit Agent or any Senior Lender from objecting in any
Insolvency or Liquidation Proceeding or otherwise to any action taken by the
Trustee or any of the Noteholders, including the seeking by the Trustee or any
Noteholder of adequate protection or the asserting by the Trustee or any
Noteholder of any of its rights and remedies under the Noteholder Documents or
otherwise.

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

                  SECTION 7. RELIANCE; WAIVERS; ETC.

                  7.1 Reliance. The consent by the Senior Lenders to the
execution and delivery of the Noteholder Documents and the grant to the Trustee
on behalf of the Noteholders of a Lien on the Common Collateral and all loans
and other extensions of credit made or deemed made on and after the date hereof
by the Senior Lenders to either Company or any Grantor shall be deemed to have
been given and made in reliance upon this Agreement. The Trustee, on behalf of
itself and the Noteholders, acknowledges that it and the Noteholders have,
independently and without reliance on the Credit Agent or any Senior Lender, and
based on documents and information deemed by them appropriate, made their own
credit analysis and decision to enter into the Indenture, this Agreement and the
transactions contemplated hereby and thereby and they will continue to make
their own credit decision in taking or not taking any action under the Indenture
or this Agreement.

                  7.2 No Warranties or Liability. The Trustee, on behalf of
itself and Noteholders, acknowledges and agrees that each of the Credit Agent
and the Senior Lenders have made no express or implied representation or
warranty, including with respect to the execution, validity, legality,
completeness, collectibility or enforceability of any of the Senior Lender
Documents, the ownership of any Common Collateral or the perfection or priority
of any Liens thereon. The Senior Lenders will be entitled to manage and
supervise their respective loans and extensions of credit under the Senior
Lender Documents in accordance with law and as they may otherwise, in their sole
discretion, deem appropriate, and the Senior Lenders may manage their loans and
extensions of credit without regard to any rights or interests that the Trustee
or any of the Noteholders have in the Common Collateral or otherwise, except as
otherwise provided in this Agreement. Neither the Credit Agent nor any Senior
Lender shall have any duty to the Trustee or any of the Noteholders to act or
refrain from acting in a manner which allows, or results in, the occurrence or
continuance of an event of default or default under

                                       15
<PAGE>
any agreements with either Company or any Subsidiary thereof (including the
Noteholder Documents), regardless of any knowledge thereof which they may have
or be charged with.

                  7.3 No Waiver of Lien Priorities.

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

                  (b) Without in any way limiting the generality of the
foregoing paragraph (but subject to the rights of the Companies and the other
Grantors under the Senior Lender Documents), the Senior Lenders, the Credit
Agent and any of them, may, at any time and from time to time, without the
consent of, or notice to, the Trustee or any Noteholder, without incurring any
liabilities to the Trustee or any Noteholder and without impairing or releasing
the Lien priorities and other benefits provided in this Agreement (even if any
