                              SECOND AMENDMENT TO
                           ATP OIL & GAS CORPORATION
                             1998 STOCK OPTION PLAN

     WHEREAS, ATP OIL & GAS CORPORATION, a Texas corporation (the "Company") has
heretofore adopted the ATP OIL & GAS CORPORATION 1998 STOCK OPTION PLAN (the
"Plan"); and

     WHEREAS, the Company desires to amend the Plan in certain respects;

     NOW, THEREFORE, the Plan shall be amended as follows, effective upon the
date this amendment is adopted by the Board of Directors of the Company:

     1.   Section 6(g) of the Plan shall be deleted and the following shall be
substituted therefor:

          "(g)  Assignability.  An ISO shall not be assignable or otherwise
     transferable except by will or the laws of descent and distribution, and
     during the lifetime of an Optionee, an option shall be exercisable only by
     him or his guardian or legal representative.  A Nonqualified Option shall
     not be assignable or otherwise transferable except (i) by will or the laws
     of descent and distribution, (ii) pursuant to a qualified domestic
     relations order as defined by the Code or Title I of the Employee
     Retirement Income Security Act of 1974, as amended, or the rules
     thereunder, or (iii) with the consent of the Committee."

     2.   Section 6(l) of the Plan shall be deleted and the following shall be
substituted therefor:

          "(l)  Change in Control.  If the Company shall be a party to a merger
     or consolidation that results in at least 40% of the total voting power
     represented by the voting stock of the Company (or the successor to the
     Company) outstanding immediately after such merger or consolidation being
     owned or controlled (including, without limitation, the power to vote) by
     persons or entities other than the shareholders of the Company immediately
     prior to such merger or consolidation (a `Transaction'), then, except as
     provided in any option agreement, upon the consummation of such
     Transaction, all outstanding options shall immediately vest and become
     exercisable and such options shall continue to be exercisable for the
     remainder of the applicable option term.  Further, if (i) the Company shall
     not be the surviving entity in a merger or consolidation (or survives only
     as a subsidiary of an entity) other than a Transaction as described in the
     preceding sentence, (ii) the Company sells, leases or exchanges or agrees
     to sell, lease or exchange all or substantially all of its assets to any
     other person or entity, (iii) the Company is to be dissolved and
     liquidated, (iv) any person or entity, including a `group' as contemplated
     by Section 13(d)(3) of the 1934 Act, acquires or gains ownership or control
     (including, without limitation, power to vote) of more than 50% of the
<PAGE>

     outstanding shares of the Company's voting stock (based upon voting power)
     or (v) as a result of or in connection with a contested election of
     Directors, the persons who were Directors of the Company before such
     election shall cease to constitute a majority of the Board (each such event
     is referred to in clauses (i), (ii), (iii) (iv) and (v) herein as a
     `Corporate Change'), no later than (x) ten days after the approval by the
     shareholders of the Company of such merger, consolidation, reorganization,
     sale, lease or exchange of assets or dissolution or such election of
     Directors or (y) thirty days after a Corporate Change of the type described
     in clause (iv), the Committee, acting in its sole discretion without the
     consent or approval of any Optionee, shall effect one or more of the
     following alternatives, which alternatives may vary among individual
     Optionee and which may vary among options held by any individual Optionee
     (1) accelerate the time at which options then outstanding may be exercised
     so that such options may be exercised in full for a limited period of time
     on or before a specified date (before or after such Corporate Change) fixed
     by the Committee, after which specified date all unexercised options and
     all rights of Optionees thereunder shall terminate, (2) require the
     mandatory surrender to the Company by selected Optionees of some or all of
     the outstanding options held by such Optionees (irrespective of whether
     such options are then exercisable under the provisions of the Plan) as of a
     date, before or after such Corporate Change, specified by the Committee, in
     which event the Committee shall thereupon cancel such options and cause the
     Company to pay to each Optionee an amount of cash per share equal to the
     excess, if any, of the `Change of Control Value' (as hereinafter defined)
     of the shares subject to such Option over the exercise price(s) under such
     options for such shares, (3) make such adjustments to options then
     outstanding as the Committee deems appropriate to reflect such Corporate
     Change (provided, however, that the Committee may determine in its sole
     discretion that no adjustment is necessary to Options then outstanding), or
     (4) provide that the number and class of shares of Common Stock covered by
     an option theretofore granted shall be adjusted so that such option shall
     thereafter cover the number and class of shares of stock or other
     securities or property (including, without limitation, cash) to which the
     Optionee would have been entitled pursuant to the terms of the agreement of
     merger, consolidation or sale of assets and dissolution if, immediately
     prior to such merger, consolidation or sale of assets and dissolution, the
     Optionee had been the holder of record of the number of shares of Common
     Stock then covered by such option.  For the purposes of clause (2) of the
     preceding sentence, the `Change of Control Value' shall equal the amount
     determined in clause (A), (B) or (C), whichever is applicable, as follows:
     (A) the per share price offered to shareholders of the Company in any such
     merger, consolidation, sale of assets or dissolution transaction, (B) the
     price per share offered to shareholders of the Company in any tender offer
     or exchange offer whereby a Corporate Change takes place, or (C) if such
     Corporate Change occurs other than pursuant to a tender or exchange offer,
     the fair market value per share of the shares into which such options being
     surrendered are exercisable, as determined by the Committee as of the date
     determined by the Committee to be the date of cancellation and surrender of
     such options.  In the event that the consideration offered to shareholders
     of the Company in any transaction described in this paragraph consists of
     anything other than cash, the Committee shall determine the fair cash
     equivalent of the portion of the consideration offered which is other than
     cash. The provisions contained in this paragraph shall not terminate any
     rights of the Optionee to further payments pursuant to any other agreement
     with the Company following a Transaction or Corporate Change."

     3.  As amended hereby, the Plan is specifically ratified and reaffirmed.

     EXECUTED this 3rd day of January, 2001.

                      PACIFIC GATEWAY EXCHANGE, INC.
                   DEBTOR-IN-POSSESSION CREDIT AGREEMENT

         THIS DEBTOR-IN-POSSESSION CREDIT AGREEMENT is dated as of December 29,
2000, among PACIFIC GATEWAY EXCHANGE, INC., a Delaware corporation (the
"Borrower"), the LENDERS (as defined below), and BANK OF AMERICA, N.A., as a
Lender and Administrative Agent.

                                 BACKGROUND

         WHEREAS, the Borrower, Pacific Gateway Exchange (Bermuda) Limited
(the "Foreign Borrower") and the Lenders entered into a Second Amended and
Restated Credit Agreement dated as of May 31, 2000 (as amended, the
"Prepetition Credit Agreement");

         WHEREAS, on the Petition Date (such term and other capitalized
terms used in these recitals shall have the meanings as set forth in
Section 1.01 hereof), the Debtor Entities filed voluntary petitions for
relief under the Bankruptcy Code with the United States Bankruptcy Court
for the Northern District of California (the "Court") (such proceedings
jointly administered under Case No. _________ are hereinafter referred to
as the "Chapter 11 Cases"), and each of the Debtor Entities continues to
operate its business and manage its properties as a debtor in possession
pursuant to Sections 1107 and 1108 of the Bankruptcy Code;

         WHEREAS, under the Prepetition Credit Agreement, as amended, and
the documents executed in connection therewith (the "Existing Loan
Papers"), the Lenders made Domestic Revolver Loans to the Borrower and
Foreign Revolver Loans to the Foreign Borrower and issued Letters of Credit
for the account of the Foreign Borrower, and the Borrower and the other
Debtor Entities guaranteed the obligations of the Foreign Borrower (the
obligations under the Existing Loan Papers being the "Existing
Obligations");

         WHEREAS, the Lenders assert that the Domestic Revolver Loans, the
Foreign Revolver Loans and the other Existing Obligations of the Debtor
Entities under the Existing Loan Papers are secured by liens on
substantially all the assets of the Debtor Entities (the "Existing
Collateral");

         WHEREAS, the Lenders assert that as of the Petition Date, the
Debtor Entities were indebted to the Lenders on account of the Existing
Obligations in an aggregate principal amount of $38,652,064, which amount
includes $22,143,226 principal amount of Domestic Revolver Loans,
guarantees of $16,456,503 principal amount of Foreign Revolver Loans and
guarantees of reimbursement obligations related to outstanding Letters of
Credit in the amount of $52,335, plus unpaid fees, expenses and accrued
interest;

         WHEREAS, the Lenders assert that all existing cash, negotiable
instruments, documents of title, securities, deposit accounts or other cash
equivalents of the Debtor Entities and the proceeds, products, offspring,
rents or profits of property of the Debtor Entities that comprise the
Existing Collateral (whether existing before or after the commencement of
the Chapter 11 Cases) constitute the cash collateral of the Lenders (the
"Cash Collateral");

                                     1

<PAGE>
         WHEREAS, the Lenders do not consent to the use of their Cash
Collateral, but require the Debtor Entities to repay the Cash Collateral to
the Lenders;

         WHEREAS, the Lenders assert that the Debtor Entities are unable to
provide the Lenders with adequate protection of the use of the Lenders'
Cash Collateral.

         WHEREAS, the Debtor Entities have requested the Lenders to provide
a revolving credit facility to the Borrower in an amount not to exceed the
DIP Availability at that time (the "DIP Loans") to fund certain budgeted
expenses;

         WHEREAS, the Lenders are willing to provide such financing only if
the diminution in the value of the Existing Collateral resulting from the
use of the DIP Loans (x) constitutes allowed administrative expenses in the
Chapter 11 Cases and (y) as more specifically set forth and subject to the
limited exceptions described, hereinbelow, is secured by first priority
liens on all the assets of the Debtor Entities; and

         WHEREAS, nothing herein is intended to nor shall constitute a
validation of the Existing Obligations or the Existing Collateral and to
the extent that any payment of Cash Collateral made to the Lenders pursuant
to this Agreement is subsequently determined in a Final Order to have been
made with respect to cash that was not subject to a Lien in favor of the
Lenders securing the Existing Obligations or such Lien is avoided, such
payment will be reversed so that the parties are returned to the status quo
ante, as set forth herein.

                                 AGREEMENT

         NOW, THEREFORE, for valuable consideration, hereby acknowledged,

credit expires without being drawn, the Lender shall transfer such Cash
Collateral to the Administrative Agent to be applied as a payment of Cash
Collateral under Section 2.05 hereof and such payment shall increase the

    2.10.     Agency Fees.

         (a) The Borrower shall pay to Administrative Agent an agency fee of

has been terminated.

         (a)  Mandatory Termination of the DIP Commitment.  The DIP Commitment
shall automatically be reduced to zero and terminate on the Maturity Date.

         (b)  No Increase in DIP Availability Due to Repayments From Asset
Sales.  The DIP Availability shall not be increased by the amount the Existing
Obligations are repaid pursuant to Section 2.05 hereof as a result of any
Asset Sales of the Borrower or any of its Subsidiaries (this provision in
and of itself not constituting permission to effectuate any Asset Sales).
As a result, the Net Proceeds of Asset Sales required to be repaid to the
Lenders pursuant to Section 2.05 will not be available to be reborrowed.

         (c)  Intentionally Omitted.

         (d)  Change of Control.  If any Change of Control shall have occurred,

         (a) The Borrower shall make each payment hereunder and under the other
Loan Papers not later than 1:00 p.m. Pacific Time on the day when due in
same day funds (by wire transfer or otherwise) to Administrative Agent, for
the account of Lenders unless otherwise specifically provided herein, at
Administrative Agent's office at Bank of America Plaza, 901 Main Street,
Dallas, Texas 75202, referencing Pacific Gateway Exchange, Inc., as DIP. No
later than the end of each day when each payment hereunder is made, the
Borrower shall notify Loan Operations at (214) 209-0989 or such other Person
as Administrative Agent may from time to time specify.

         (b) Unless Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due hereunder that the
Borrower will not make payment in full, Administrative Agent may assume
that such payment is so made on such date and may, in reliance upon such
assumption, make distributions to Lenders. If and to the extent the
Borrower has not made such payment in full, each Lender shall repay to
Administrative Agent forthwith on demand the applicable amount distributed,
together with interest thereon at the Federal Funds Rate, from the date of
distribution until the date of repayment. The Borrower hereby authorizes
each Lender, if and to the extent payment is not made when due hereunder,
to charge the amount so due against any account of the Borrower with such
Lender.

         (c)  All payments under the Loan Papers shall be made in United States
dollars.

         (d)  Whenever any payment to be made hereunder or under any other Loan
Papers shall be stated to be due on a day other than a Business Day, such
payment shall be made on the next succeeding Business Day, and such
extension of time shall be included in the computation of interest or fees,
if applicable.

     2.14.    Application of Payments; Increase of DIP Availability.

         (a)  Repayments of the obligations under the Prepetition Credit
Agreement shall be applied as set forth in the Prepetition Credit Agreement.

         (b)  To the extent Cash Collateral is applied after the Closing Date
to reduce the Existing Obligations, other than repayments from the proceeds of
Asset Sales, and to the extent such repayments are not reborrowed pursuant
to this Agreement, the DIP Availability shall be increased by such amount,
subject in each case to Section 2.11 of this Agreement; and provided that
in no case shall the DIP Availability exceed the DIP Commitment.

    2.15.    Intentionally Omitted.

    2.16.    Use of Proceeds.  The Advances shall be available (and the Borrower
and its Subsidiaries shall use such proceeds) only in accordance with the
Approved Budget and not for any purpose prohibited by Section 6.08 hereof.

    2.17.    Collateral and Collateral Call.

         (a) DIP Obligations. To the extent that any Debtor Entity's use of any
funds advanced pursuant to this Agreement results in diminution of the
value of the Existing Collateral, the DIP Obligations are secured by (i) a
first priority security interest, senior to the security interest securing
the Existing Obligations, in all tangible and intangible assets of the
Borrower, including current and future IRU Agreements, but junior to valid,
non-avoidable Liens existing on the Petition Date in favor of Persons other
than the Lenders which Liens are senior to the Existing Collateral, junior
to the Liens set forth in clauses (h) and (i) of the definition of
Permitted Liens and excluding (A) certain assets set forth on Schedule 8.13
hereof or approved by the Majority Lenders that may not by contract or law
be pledged or assigned, (B) the Excluded IRU Agreements, (C) the Avoidance
Actions; and (D) Capital Stock in Subsidiaries organized under the laws of
foreign countries (which are covered elsewhere in this Section 2.17(a)),
(ii) a first priority security interest senior to the security interest
securing the Existing Obligations, in 66% of the Capital Stock of Foreign
Borrower; (iii) a first priority security interest, senior to the security
interest securing Existing Obligations, in 100% of the Capital Stock of all
Domestic DB Subsidiaries; (iv) a first priority security interest, senior
to the security interest securing the Existing Obligations, in 66% of
Capital Stock of all Foreign DB Subsidiaries that are owned by a Domestic
DB Subsidiary; (v) Guaranties by all Domestic DB Subsidiaries (other than
Inactive Debtors and PGE Fiber), which Guaranties shall be secured by a
first perfected security interest, senior to the security interest securing
the Existing Obligations, in all tangible and intangible assets (including
intercompany loans) of such Domestic DB Subsidiaries including current and
future IRU Agreements, but junior to valid, non-avoidable Liens existing on
the Closing Date in favor of Persons other than the Lenders which Liens are
senior to the Existing Collateral and which are Permitted Liens, and
excluding (A) certain assets set forth on Schedule 8.13 hereof or approved
by the Majority Lenders that may not by contract or law be pledged or
assigned, (B) the Excluded IRU Agreements, (C) the Avoidance Actions, (D)
any assets of PGE Fiber and (E) Capital Stock in Subsidiaries organized
under the laws of foreign countries to the extent that such stock would not
be pledged by the Borrower pursuant to this Section 2.17(a) if the
Subsidiary were owned directly by the Borrower (collectively, together with
all other Properties or assets of the Borrowers, the Subsidiaries and other
Persons securing the Obligations under the DIP Loan from time to time, the
"Domestic Collateral"). The Borrower agrees that it will, and will cause
the Domestic DB Subsidiaries to execute and deliver, or cause to be
executed and delivered, such documents as the Administrative Agent may from
time to time request to create and perfect a Lien for the benefit of the
Administrative Agent and the Lenders in the Domestic Collateral; provided,
that no such steps shall be required to perfect security interests in the
Domestic Collateral of the Debtor Entities.

                                     24
<PAGE>
         (b) Perfection; Collateral Call. The security interests in the Domestic
Collateral of the Debtor Entities shall be deemed perfected without the
Administrative Agent or the Lenders taking any action whatsoever.
Notwithstanding the foregoing, the Debtor Entities agree, promptly upon
request by the Administrative Agent, to take all actions necessary or
advisable to promptly grant and perfect to the Administrative Agent on
behalf of the Lenders a Lien and/or security interest in all or any portion
of the Domestic Collateral (whether through delivery of Capital Stock or
otherwise), including to pledge/mortgage or grant a first priority security
interest in real property to secure the Obligations, provided that under no
circumstances shall the Borrower or its Subsidiaries be required to grant a
Lien and/or security interest in assets which are prohibited by Law.

     2.18. Superpriority Nature of Obligations; Carveout. To the extent that
any Debtor Entity's use of any funds advanced pursuant to this Agreement
results in diminution of the value of the Existing Collateral, the DIP
Obligations shall constitute allowed administrative expense claims in the
Chapter 11 Cases (other than the bankruptcy cases of the Inactive Debtors)
with priority under Section 364(c)(1) of the Bankruptcy Code over any and
all other administrative expenses of the kind specified or ordered pursuant
to any provision of the Bankruptcy Code, including Sections 105, 326, 328,
330, 331, 503(b), 506(c), 507(a) and 507(b) of the Bankruptcy Code;
provided that, the priority status of the DIP Obligations and the Liens
securing the same shall not extend to Avoidance Actions (or the proceeds of
Avoidance Actions) and shall be subject to: (i) fees payable to the clerk
of the Court or the United States Trustee pursuant to 28 U.S.C.
Section 1930(a)(6); (ii) after and from the date of the occurrence of an Event
of Default (to the extent that such Event of Default is continuing and has
not been waived by the Lenders), professional fees and expenses (including
the fees and expenses of DSI) allowed in the Chapter 11 Cases in an
aggregate amount (determined without regard to fees and expenses awarded or
otherwise paid on an interim basis or fees and expenses satisfied by draws
on a pre-petition retainer, without duplication) not to exceed $600,000;
and (iii) up to $50,000 of fees, in the aggregate, payable to any Chapter 7
trustee and trustee's counsel appointed for the estate of any Debtor
Entity.

     2.19. Reservation with Respect to Existing Obligations and Existing
Collateral. Nothing in this Agreement shall be deemed to validate any of
the Existing Obligations or any of the Existing Collateral. To the extent
that (x) any payment is made to the Lenders pursuant to Section 2.05(a) of
this Agreement and it is subsequently determined by a Final Order that the
funds used to make such payment did not constitute the Lenders' Cash
Collateral or the Lien or Obligations related to such Cash Collateral is
avoided (the "Reversed Cash Collateral Payment"), or (y) any payment is
made to the Lenders pursuant to Section 2.05(b), is not reborrowed, and it
is subsequently determined by a Final Order that the funds used to make
such payment (i) constituted a Reversed Cash Collateral Payment, (ii) were
not subject to the Liens securing DIP Obligations provided under Section
2.17, and (iii) exceeded the amount of the administrative priority provided
under Section 2.18 (collectively a "Reversed DIP Payment"), then the
parties shall be returned to the status quo ante. Any reborrowings of any
Reversed Cash Collateral Payments that have been made as DIP Advances under
this Agreement shall be reversed so that such DIP Advances are deemed to be
repaid and the Existing Obligations are increased by a corresponding
amount, in each case without any cash payments being made. Any Reversed DIP
Payment that is not reborrowed and any Reversed DIP Payment and any
Reversed Cash Collateral Payment that is not reborrowed may be avoided to
the extent it allows the Lenders to receive a distribution in excess of
their share of such Reversed Cash Collateral Payment or Reversed DIP
Payment, pro rata with general unsecured non-priority claims of the
applicable Debtor Entity.

    5.01. Representations and Warranties.  The Borrower hereby represents and
warrants to each Lender as follows:

         (a) The respective jurisdictions of incorporation and percentage
ownership of its subsidiaries, including a designation of the DB
Subsidiaries, the FB Subsidiaries and the Foreign DB Subsidiaries, on the
Closing Date and listed on Schedule 5.01(a) hereto are true and correct.
Each of the Debtor Entities is an entity duly organized, validly existing
and in good standing under the laws of its state or country of organization
except (i) to the extent contemplated in the Approved Budget, (ii) as
necessary to conduct an orderly liquidation of such Properties, or (iii)
where the failure to qualify could not reasonably be expected to cause a
Material Adverse Change. Subject to compliance with any applicable
provision of the Bankruptcy Code, each of the Debtor Entities has the
corporate power and corporate authority to own its properties and to carry
on its business as now being conducted. Each of the Debtor Entities is duly
qualified, in good standing and authorized to do business in each
jurisdiction in which the character of its Properties or the nature of its
business requires such qualification or authorization, except (i) to the
extent contemplated in the Approved Budget, (ii) as necessary to conduct
orderly liquidations of such Properties, or (iii) where the failure to so
qualify could not reasonably be expected to cause a Material Adverse
Change.
                                      29
<PAGE>

         (b) Subject to compliance with any applicable provisions of the
Bankruptcy Code, each Obligor has the corporate power and has taken all
necessary corporate action to authorize it to borrow hereunder and to
execute, deliver and perform the Loan Papers to which it is party in
accordance with the terms thereof, and to consummate the transactions
contemplated thereby. Each Loan Paper has been duly executed and delivered
by each Obligor executing it and, upon Court approval, each of the Loan
Papers will be a legal, valid and binding obligation of each Obligor, as
applicable, enforceable in accordance with its terms, subject to the
following qualifications: (i) equitable principles generally, and (ii)
bankruptcy, insolvency, liquidation, reorganization, reconstruction and
other similar laws affecting enforcement of creditors' rights generally.

         (c) The execution, delivery and performance by the Borrower and its
Subsidiaries of the other Loan Papers to which they are respectively a
party, and the consummation of the transactions contemplated thereby, do
not and will not, upon Court approval, (i) require any consent or approval
not already obtained, (ii) violate any Applicable Law, (iii) conflict with,
result in a breach of, or constitute a default under the articles of
incorporation or bylaws (or memorandum of association or by-laws) of the
Borrower and its Subsidiaries, or under any material License, indenture,
agreement or other instrument, to which any of the Debtor Entities is a
party or beneficiary of, or by which they or their respective Properties
may be bound, or (iv) result in or require the creation or imposition of
any Lien upon or with respect to any property now owned or hereafter
acquired by any Obligor, except Permitted Liens, except, with respect to
any of the foregoing, which could not reasonably be expected to cause a
Material Adverse Change.

         (d)  Intentionally omitted.

         (e)  Intentionally omitted.

         (f)  Except as set forth on Schedule 5.01(f) hereto, as of the Closing
Date, the Borrower is not aware of any event or circumstance constituting
noncompliance by any of the Debtor Entities (or any Person alleging
noncompliance) with any rule or regulation of the FCC or any applicable PUC
that could reasonably be expected to cause a Material Adverse Change. On
each date after the Closing Date on which this representation is deemed to
be made, the Borrower is not aware of any event or circumstance
constituting noncompliance by the Debtor Entities (or any Person alleging
noncompliance) with any rule or regulation of the FCC or any applicable
PUC, which such event or circumstance could reasonably be expected to cause
a Material Adverse Change.

         (g)  On the Closing Date, the Obligors have good and indefeasible
title to, or a valid leasehold interest in, all of their material assets and
Properties. On each date after the Closing Date on which this
representation is deemed to be made, the Obligors have good and
indefeasible title to, or a valid leasehold interest in, all of their
material assets and Properties, in which any such failure could reasonably
be expected to cause a Material Adverse Change. Except Permitted Liens,
there are no Liens on the assets of the Obligors.

                                  30
<PAGE>

         (h)  On the Closing Date, except for (i) the Chapter 11 Cases or the
Chapter 11 cases of any other Domestic DB Subsidiaries, (ii) litigation
stayed by the filing of the Chapter 11 Cases and (iii) as reflected on
Schedule 5.01(h) hereto or publicly reported shareholder class action
suits, there is no material action, suit, proceeding or any other
Litigation pending against, any of the Obligors, or in any other manner
relating directly and materially adversely to any of the Obligors, or any
of their material Properties, in any court or before any arbitrator of any
kind or before or by any governmental body which could reasonably be
expected to cause a Material Adverse Change. On each date after the Closing
Date on which this representation is deemed to be made, there is no action,
suit, proceeding or any other Litigation pending against, any of the
Obligors, or in any other manner relating to any of the Obligors, or any of
their Properties, in any court or before any arbitrator of any kind or
before or by any governmental body, which could reasonably be expected to
cause a Material Adverse Change other than (i) the Chapter 11 Cases or the
Chapter 11 cases of any other Domestic DB Subsidiaries, (ii) litigation
stayed by the filing of the Chapter 11 Cases and (iii) litigation described
on Schedule 5.01(h) hereto or publicly reported shareholder class action
suits.

         (i) To the knowledge of the Debtor Entities, and except to the extent
excused by the Court, the Bankruptcy Code or Applicable Law, all material
federal, state and other Tax returns of the any of the Obligors required by
law to be filed have been duly filed and all Taxes, assessments and
governmental charges or levies imposed upon of any of the Obligors or any
of their Properties, income, profits and assets, except those that are
diligently contested in good faith by the Obligors and for which adequate
reserves have been established in accordance with GAAP, and no Lien (other
than a Permitted Lien) has attached and no foreclosure, distrait, sale or
similar proceedings have been commenced.

         (j) The Borrower has furnished or caused to be furnished to the
Lenders copies of its financial statements as of September 30, 2000 as set
forth in its report on Form 10Q, which have been prepared in good faith and are
complete in all material respects. Each such statement presents fairly in
all material respects and in accordance with GAAP the financial position of
the Borrower and its Subsidiaries as at such dates, and the results of
operations for the periods then ended. The Obligors and, to the best of the
Borrower's knowledge, any of its Subsidiaries have no material liabilities,
contingent or otherwise, nor material losses, except as disclosed in
writing to the Lenders prior to the Closing Date or as disclosed on any
subsequent financial statements.

         (k) None of the Borrower or its Controlled Group maintains or
contributes to any Plan other than those disclosed to the Administrative
Agent in writing. Each such Plan is in compliance in all material respects
with the applicable provisions of ERISA, the Code, and any other applicable
Federal or state law, rule or regulation. With respect to each Plan of the
Borrower and each member of its Controlled Group (other than a
Multiemployer Plan), all reports required under ERISA or any other
Applicable Law to be filed with any governmental authority, the failure of

                                 31
<PAGE>

which to file could reasonably result in liability of the Borrower or any
member of its Controlled Group in excess of $100,000, have been duly filed.
All such reports are true and correct in all material respects as of the
date given. No such Plan of the Borrower or any member of its Controlled
Group has any accumulated funding deficiency (as defined in Section 412(a)
of the Code) (without regard to any waiver granted under Section 412 of the
Code), nor has any funding waiver from the Internal Revenue Service been
received or requested. None of the Borrower or any member of its Controlled
Group has failed to make any contribution or pay any amount due or owing as
required by Section 412 of the Code or Section 302 of ERISA or the terms of
any such Plan prior to the due date under Section 412 of the Code and
Section 302 of ERISA. There has been no ERISA Event or any event requiring
disclosure under Section 4041(c)(3)(C), 4068(f), 4063(a) or 4043(b) of
ERISA with respect to any Plan or trust of the Borrower or any member of
its Controlled Group since the effective date of ERISA. The value of the
assets of each Plan (other than a Multiemployer Plan) of the Borrower and
each member of its Controlled Group equaled or exceeded the present value
of the benefit liabilities, as defined in Title IV of ERISA, of each such
Plan as of the most recent valuation date using Plan actuarial assumptions
at such date. There are no pending or, to the best of the Borrower's
knowledge, threatened claims, lawsuits or actions (other than routine
claims for benefits in the ordinary course) asserted or instituted against,
and neither the Borrower nor any member of its Controlled Group has
knowledge of any threatened Litigation or claims against, (i) the assets of
any Plan or trust or against any fiduciary of a Plan with respect to the
operation of such Plan, or (ii) the assets of any employee welfare benefit
plan within the meaning of Section 3(1) or ERISA, or against any fiduciary
thereof with respect to the operation of any such plan. None of the
Borrower or any member of its Controlled Group has engaged in any non-exempt
prohibited transactions, within the meaning of Section 406 or Section 4.08
of ERISA or Section 4975 of the Code, in connection with any Plan. None of
the Borrower or any member of its Controlled Group has incurred or
reasonably expects to incur (A) any liability under Title IV of ERISA
(other than premiums due under Section 4007 of ERISA to the PBGC), (B) any
withdrawal liability (and no event has occurred which with the giving of
notice under Section 4219 of ERISA would result in such liability) under
Section 4201 of ERISA as a result of a complete or partial withdrawal
(within the meaning of Section 4203 or 4205 of ERISA) from a Multiemployer
Plan, or (C) any liability under Section 4062 of ERISA to the PBGC or to a
trustee appointed under Section 4042 of ERISA. None of the Borrower, any
member of its Controlled Group, or any organization to which the Borrower
or any member of its Controlled Group is a successor or parent corporation
within the meaning of ERISA Section 4069(b), has engaged in a transaction
within the meaning of ERISA Section 4069. None of the Borrower or any
member of its Controlled Group maintains or has established any welfare
benefit plan within the meaning of Section 3(1) of ERISA which provides for
continuing benefits or coverage for any participant or any beneficiary of
any participant after such participant's termination of employment except
as may be required by the Consolidated Omnibus Budget Reconciliation Act of
1985, as amended ("COBRA") and the regulations thereunder, and at the
expense of the participant or the beneficiary of the participant, or
retiree medical liabilities. Each of the Borrower and its Controlled Group
which maintains a welfare benefit plan within the meaning of Section 3(1)
of ERISA has complied in all material respects with any applicable notice
and continuation requirements of COBRA and the regulations thereunder.

         (l)  None of the Obligors is engaged principally or as one of its
important activities, in the business of extending credit for the purpose
of purchasing or carrying any margin stock within the meaning of
Regulations T, U and X of the Board of Governors of the Federal Reserve
System, and no part of the proceeds of the DIP Advances will be used to
purchase or carry any margin stock (as defined by Regulation U) or to
extend credit to others for the purpose of purchasing or carrying any
margin stock. Not more than 25% of the assets of any of the Obligors are
margin stock (as defined by Regulation U), and none of the Capital Stock of
the Borrower's Subsidiaries is margin stock. None of the Obligors, nor any
agent acting on their behalf, has taken or will knowingly take any action
which might cause this Agreement or any Loan Papers to violate any
regulation of the Board of Governors of the Federal Reserve System or to
violate the Exchange Act, in each case as in effect now or as the same may
hereafter be in effect.

Subsidiaries are in compliance with all of the material provisions of their
articles of incorporation and by-laws.

         (n)  Neither the Borrower, nor any of its Subsidiaries is required
to register under the provisions of the Investment Company Act of 1940, as
amended. Neither the entering into or performance by the Borrower of this
Agreement nor the issuance of the DIP Notes, nor the execution, delivery
and performance of the obligations under the Loan Papers by the Borrower
and its Subsidiaries, violates any provision of such act or requires any
consent, approval, or authorization of, or registration with, the
Securities and Exchange Commission or any other governmental or public body
of authority pursuant to any provisions of such act.

         (o)  On the Closing Date, none of the Obligors has any actual
knowledge or reason to believe that any substance deemed hazardous by any
applicable Environmental Law, has been installed on any real property now
owned by the Borrower or any of its Subsidiaries, except (i) for hazardous
substances the presence of which is not in violation of law and (ii) as
disclosed in writing to the Lenders. On each date after the Closing Date on
which this representation is deemed to be made, none of the Obligors has
any actual knowledge or reason to believe that any substance deemed
hazardous by any applicable Environmental Law, has been installed in
violation of law on any real property now owned by the Borrower or any of
its Subsidiaries except as disclosed to the Lenders in writing, and which
could, in the reasonable judgment of the Borrower, be expected to cause a
Material Adverse Change. As of the Closing Date, none of the Obligors is in
violation of or subject to any existing, pending or, to the best of
Borrower's knowledge, threatened investigation or inquiry by any
governmental authority or to any material remedial obligations under any
applicable Environmental Laws, and this representation and warranty would
continue to be true and correct following disclosure to the applicable
governmental authorities of all relevant facts, conditions and
circumstances, if any, pertaining to any real property of the Borrower or
its Subsidiaries. On each date after the Closing Date on which this
representation is deemed to be made, none of the Obligors is in violation
of or subject to any existing, pending or, to the best of either Borrower's
knowledge, threatened investigation or inquiry by any governmental
authority or to any material remedial obligations under any applicable
Environmental Laws which could reasonably be expected to cause a Material
Adverse Change, and this representation and warranty would continue to be
true and correct following disclosure to the applicable governmental
authorities of all relevant facts, conditions and circumstances, if any,
pertaining to any real property of the Borrower or its Subsidiaries. None
of the Obligors is required to obtain any permits, Licenses or similar
authorizations to construct, occupy, operate or use any buildings,
improvements, fixtures, and equipment forming a part of any real property
of the Borrower or any of its Subsidiaries by reason of any applicable
Environmental Laws, except those that have been obtained. As of the Closing
Date, none of the Obligors has actual knowledge or reason to believe, after
reasonable investigation, that any hazardous substances or solid wastes
have been disposed of or otherwise released on or to the real property of
the Borrower or any of its Subsidiaries in violation of any applicable
Environmental Law, except as could be not reasonably be expected to cause a
Material Adverse Change. On each date after the Closing Date on which this
representation is deemed to be made, none of the Obligors has actual
knowledge or reason to believe, that any hazardous substances or solid
wastes have been disposed of or otherwise released on or to the real
property of either Borrower any of its Subsidiaries, within the meaning of
the applicable Environmental Laws, except as disclosed to the Lenders and
which such disposal or release could not reasonably be expected to cause a
Material Adverse Change.

         (p)  All Capital Stock of the Obligors has been duly authorized and
validly issued, and is fully paid and nonassessable. The Capital Stock
described on Schedule 5.01(a) hereto constitutes all the issued and
outstanding Capital Stock of the Borrower and all the direct and indirect
Subsidiaries of the Borrower. No Person has conversion rights with respect
to, or any subscription rights, calls, commitments or claims of any
character for, or any repurchase or redemption options relating to, the
Capital Stock of the Borrower or its Subsidiaries, other than those rights
that have been waived, except as disclosed on Schedule 5.01(p). The Capital
Stock of the Obligors when issued or sold, was either (i) registered or
qualified under applicable federal or state securities laws, or (ii) exempt
therefrom.

         (q)  No broker's, finder's or other fee or commission will be payable
by the any of the Obligors (other than to the Lenders or their Affiliates
hereunder) with respect to the making of the DIP Commitment or the DIP
Advances hereunder. The Borrower agrees to indemnify and hold harmless the
Administrative Agent and each Lender from and against any claims, demand,
liability, proceedings, costs or expenses asserted with respect to or
arising in connection with any such fees or commissions.

         (r)  Intentionally Omitted.

         (s)  Intentionally Omitted.

         (t)  Neither this Agreement nor any other document, certificate or
statement taken as a whole which has been furnished to any Lender in
connection with this Agreement contain any untrue statement of a material
fact or omitted to state a material fact necessary in order to make the
statement contained herein and therein not misleading at the time it was
furnished in any material respect.

         (u)  Intentionally Omitted.

         (v)  Schedule 5.01(v) is an accurate and comprehensive list of each of
the Borrower's and its Subsidiaries accounts maintained with financial
institutions identified by the name in which the account has been
established, the location of such account, the name and address of the
financial institution holding such account and the number of such account.

         (w) The Chapter 11 Cases were commenced on the applicable Petition
Date in accordance with applicable law and proper notice thereof and of the
hearing for the approval of the Interim and Final Borrowing Orders has been
given as identified in the certificate of service filed with the Court.

     5.02. Survival of Representations and Warranties. All representations
and warranties made under this Agreement and the other Loan Papers shall be
deemed to be made at and as of the Closing Date and at and as of the date
of each Advance, and each shall be true and correct in all material
respects when made. All such representations and warranties shall survive,
and not be waived by, the execution hereof by any Lender, any investigation
or inquiry by any Lender, or by the making of any DIP Advance under this
Agreement.

                        ARTICLE V1. GENERAL COVENANTS

         So long as any of the Obligations are outstanding and unpaid or
the DIP Commitment is outstanding (whether or not the conditions to
borrowing have been or can be fulfilled):

     6.01.  Preservation of Existence and Similar Matters.

            (a) To the extent provided for in the Approved Budget, and except
with respect to orderly liquidations and Asset Sales, or approved by the Lenders

Subsidiaries to, preserve and maintain, or timely obtain and thereafter
preserve and maintain (i) material rights, franchises, authorizations,
consents, privileges and all other material Licenses from federal, state
and local governmental bodies and any Tribunal (regulatory or otherwise)
which the Borrower or such Subsidiary deems reasonably necessary or
advisable to conduct its business in the ordinary course, and (ii) its
existence (except as permitted by Section 8.05 hereof); and

            (b) To the extent provided for in the Approved Budget and except
with respect to orderly liquidations and Asset Sales, or approved by the
Lenders or the Court, the Borrower shall, and, subject to the due authority of
its Subsidiaries' then presiding directors, shall cause each of the Domestic DB
Subsidiaries to, qualify and remain qualified and authorized to do business
in each jurisdiction in which the character of its Properties or the nature
of its business requires such qualification or authorization, except where
the failure to do so could not be reasonably expected to cause a Material
Adverse Change.

     6.02.  Business; Compliance with Applicable Law. Except with respect to
orderly liquidations and Asset Sales, or approved by the Lenders or the
Court, the Borrower shall, and shall cause the Domestic DB Subsidiaries to
(a) engage primarily in the business of telecommunications and internet,
and activities related thereto, and (b) comply in all material respects
with the requirements of all Applicable Law, except where the failure to do
so could not reasonably be expected to cause a Material Adverse Change.

Approved Budget and except with respect to orderly liquidations and Asset
Sales, or approved by the Lenders or the Court, the Borrower shall cause each
of the Domestic DB Subsidiaries to, maintain or cause to be maintained all their
material Properties necessary to the conduct of their business (whether
owned or held under lease) in reasonably good repair, working order and
condition, taken as a whole, and from time to time make or cause to be made
all appropriate repairs, renewals, replacements, additions, betterments and
improvements thereto.

accurate and complete records of its respective assets. The Borrower shall,
and shall cause each of its Domestic DB Subsidiaries to maintain a fiscal
year ending on December 31.

     6.05.  Insurance. The Borrower shall, and shall cause each of the Domestic
DB Subsidiaries to, maintain insurance (including self insurance with respect
to their deductibles) from responsible companies in such amounts and against
such risks as shall be customary and usual in the industry for companies of
similar size and capability, but in no event less than the amount and types
insured as of the Closing Date; provided that the requisite insurance coverage
hereunder may decrease or terminate during the life of this Agreement to the
extent of a winding down or termination of the Borrower's or its Subsidiaries'
business activities, as contemplated in the Approved Budget. The Borrower shall
or shall cause certificates of insurance to be delivered to the Administrative
Agent, in the case of liability insurance, naming the Administrative Agent as
additional insured, and in the case of property and casualty insurance on all

the Domestic DB Subsidiaries to, pay and discharge all Taxes, assessments
and governmental charges or levies imposed upon it or its income,
Properties, profits or assets prior to the date on which penalties attach
thereto, which, if unpaid, might become a Lien upon any of their Properties
or assets except those Taxes, assessments and charges contested by the
Borrower or its Subsidiaries diligently in good faith, and for which
adequate reserves have been established in accordance with GAAP. The
Borrower shall, and shall cause each of the Domestic DB Subsidiaries to,
timely file all material information returns required by federal, state or
local Tax authorities.

     6.07.  Visits and Inspections. The Borrower shall, and shall cause each of
its Subsidiaries to, promptly, permit representatives of the Administrative

directly or indirectly, (i) to finance or make any payments prohibited
under subsection 8.07; or (ii) to finance in any way any adversary action,
suit, arbitration, proceeding or other litigation of any type relating to
or in connection with this Agreement, the Prepetition Credit Agreement or

    6.09.  Indemnity.

       (a)  Except with respect to Avoidance Actions, the Borrower shall, and
shall cause each of the Domestic DB Subsidiaries (other than PGE Fiber and
the Inactive Debtors) to, defend, protect, indemnify and hold harmless the
Administrative Agent, each Lender, each of their respective Affiliates, and
each of their respective (including such Affiliates') officers, directors,
employees, agents, attorneys, shareholders and consultants (including,
without limitation, those retained in connection with the satisfaction or
attempted satisfaction of any of the conditions set forth herein) of each
of the foregoing (collectively, "Indemnitees") from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, claims, costs, expenses and disbursements of any kind or nature
whatsoever (including, without limitation, the reasonable fees and
disbursements of counsel for such Indemnitees in connection with any
investigative, administrative or judicial proceeding, whether or not such
Indemnitees shall be designated a party thereto), imposed on, incurred by,
or asserted against such Indemnitees (whether direct, indirect or
consequential and whether based on any federal, state, or local laws and
regulations), under common law or at equitable cause, or on contract, tort
or otherwise, arising from or connected with the past, present or future
operations of the Borrower or any of its Subsidiaries, or any of their
predecessors in interest, in any manner relating to or arising out of this
Agreement, the Loan Papers, or any act, event or transaction or alleged
act, event or transaction relating or attendant thereto, the making of any
participations in the DIP Advances and the management of the DIP Advances,
including in connection with, or as a result, in whole or in part, of any
negligence of Administrative Agent or any Lender (other than those matters
raised exclusively by a participant against the Administrative Agent or any
Lender and not the Borrower), or the use or intended use of the proceeds of
the DIP Advances hereunder, or in connection with any investigation of any
potential matter covered hereby, but excluding any claim or liability to
the extent that it arises as the result of the gross negligence or willful
misconduct of any Indemnitee, as finally judicially determined by a court
of competent jurisdiction (collectively, the "Indemnified Matters").

       (b)  In addition, the Borrower shall, and shall cause each of the
Domestic DB Subsidiaries (other than PGE Fiber and the Inactive Debtors)
to, periodically, upon request, reimburse each Indemnitee for its
reasonable legal and other actual expenses (including the cost of any
investigation and preparation) incurred in connection with any Indemnified
Matter. If for any reason the foregoing indemnification is unavailable to
any Indemnitee or insufficient to hold any Indemnitee harmless with respect
to Indemnified Matters, then the Borrower and the Domestic DB Subsidiaries
shall contribute to the amount paid or payable by such Indemnitee as a
result of such loss, claim, damage or liability in such proportion as is
appropriate to reflect not only the relative benefits received by the
Borrower or such Subsidiaries, and either Borrower's stockholders or its
Subsidiaries' stockholders, on the one hand and such Indemnitee on the
other hand but also the relative fault of the Borrower or such Subsidiary
and such Indemnitee, as well as any other relevant equitable
considerations. The reimbursement, indemnity and contribution obligations
under this Section shall be in addition to any liability which the Borrower
or its Subsidiaries may otherwise have, shall extend upon the same terms
and conditions to each Indemnitee, and shall be binding upon and inure to
the benefit of any successors, assigns, heirs and personal representatives
of the Borrower and the Domestic DB Subsidiaries, the Administrative Agent,
the Lenders and all other Indemnitees. This Section shall survive any
termination of this Agreement and payment of the Obligations.

                                  37
<PAGE>

     6.10.  Environmental Law Compliance. The use of which the Borrower or
any of its Subsidiaries intends to make of any real Property owned by it will
not result in the disposal or other release of any hazardous substance or solid
waste on or to such real Property in violation of any Environmental Law
that could reasonably be expected to cause a Material Adverse Change. As
used herein, the terms "hazardous substance" and "release" as used in this
Section shall have the meanings specified in CERCLA (as defined in the
definition of applicable Environmental Laws), and the terms "solid waste"
and "disposal" shall have the meanings specified in RCRA (as defined in the
definition of applicable Environmental Laws); provided, however, that if
CERCLA or RCRA is amended so as to broaden the meaning of any term defined
thereby, such broader meaning shall apply subsequent to the effective date
of such amendment; and provided further, to the extent that any other law
applicable to the Borrower or any of its Subsidiaries or any of their
properties and assets establishes a meaning for "hazardous substance,"
"release," "solid waste," or "disposal" which is broader than that
specified in either CERCLA or RCRA, such broader meaning shall apply. The
Borrowers shall, and shall cause the Domestic DB Subsidiaries (other than
PGE Fiber) to, indemnify and hold the Administrative Agent and each Lender
harmless from and against, and to reimburse them with respect to, any and
all claims, demands, causes of action, loss, damage, liabilities, costs and
expenses (including reasonable attorneys' fees and courts costs) of any
kind or character, known or unknown, fixed or contingent, asserted against
or incurred by any of them at any time and from time to time by reason of
or arising out of (a) the failure of the Borrower or any of its
Subsidiaries (other than PGE Fiber (Bermuda) and PGE Fiber) to perform any
obligation hereunder regarding asbestos or applicable Environmental Laws,
(b) any violation on or before the Release Date of any applicable
Environmental Law in effect on or before the Release Date, and (c) any act,
omission, event or circumstance existing or occurring on or prior to the
Release Date (including without limitation the presence on such real
Property or release from such real Property of hazardous substances or
solid wastes disposed of or otherwise released on or prior to the Release
Date), resulting from or in connection with the ownership of the real
Property, regardless of whether the act, omission, event or circumstance
constituted a violation of any applicable Environmental Law at the time of
its existence or occurrence, or whether the act, omission, event or
circumstance is caused by or relates to the negligence of any indemnified
Person; provided, that the Borrower shall not be under any obligation to
indemnify the Administrative Agent or any Lender to the extent that any
such liability arises as the result of the gross negligence or willful
misconduct of such Person, as finally judicially determined by a court of
competent jurisdiction. The provisions of this paragraph shall survive the
Release Date and shall continue thereafter in full force and effect.

     6.11.  Bankruptcy Schedules. The Debtor Entities will exercise their
reasonable best efforts to fully and accurately identify all Prepetition
Debt (and all amounts owing in respect thereof) of the Debtor Entities as
of the Petition Date on the Debtors' Schedule of Assets and Liabilities to
be filed with the Court, as they may be amended in accordance with the
Bankruptcy Rules.

     6.12.  Subsidiary Designation. The Borrower agrees that each Subsidiary on
the Closing Date will remain a Subsidiary until the Obligations have been
repaid in full and the Commitment has been terminated, except for
Subsidiaries to be dissolved pursuant to the Approved Budget, pursuant to
an orderly liquidation, pursuant to an Asset Sale or with the consent of
the Lenders.
                                    38
<PAGE>

     6.13.  Accounts. The Borrower shall not, and shall not permit any of the
Domestic DB Subsidiaries, to change or create any new banking account
without the prior written consent of the Lenders or as approved by the
Court, except for such Debtor-in-Possession accounts as may be required by
the Bankruptcy Code, Bankruptcy Rules or the Office of the United States
Trustee, and which, in each case, are disclosed and described to the
Lenders.

                     ARTICLE VII. INFORMATION COVENANTS

the DIP Commitment is outstanding (whether or not the conditions to
borrowing have been or can be fulfilled), the Borrower shall furnish or

Material Adverse Change, or result in the loss or suspension of any

<PAGE>

provided that each of the above-described actions and/or documents shall be
in form and substance reasonably satisfactory to Administrative Agent.

     9.02. Remedies upon Default. Administrative Agent may at its election, or
shall at the direction of the Majority Lenders, (notwithstanding the
provisions of Section 362 of the Bankruptcy Code and without application or
motion to, or order from, the Court), do any one or more of the following:

          (a) If any Event of Default set forth in Sections 9.01(a) or 9.01(e)
shall occur and be continuing:

                           (i) Declare the entire unpaid balance of all
         Obligations immediately due and payable, whereupon they shall be
         due and payable without diligence, presentment, demand, protest,
         notice of protest or intent to accelerate, or notice of any other
         kind (except notices specifically provided for under Section 9.01
         hereof), all of which are hereby expressly waived (except to the
         extent waiver of the foregoing is not permitted by applicable
         Law);

                           (ii) Reduce any claim of Administrative Agent
         and Lenders to judgment; and

                           (iii) Exercise any Rights afforded under any
         Loan Papers, by Law, including but not limited to the UCC, at
         equity, or otherwise; any other provision of this Agreement or any
         other Loan Papers to the contrary notwithstanding, with respect to
         the foregoing, Administrative Agent shall give the Borrower,
         counsel to any official committees in respect of the Chapter 11
         Cases and the office of the United States Trustee three (3)
         Business Days prior written notice (which notice shall be
         delivered by facsimile or overnight courier) of the exercise of
         its rights and remedies with respect to the Domestic Collateral
         and file a copy of such notice with the clerk of the Court.
         Neither the Administrative Agent nor the Lenders shall have any
         obligation of any kind to make a motion or application to the
         Court to exercise their rights and remedies set forth or referred
         to in this Agreement or in the other Loan Documents.

          (b) With respect to any Events of Default other than set forth in
Sections 9.01(a) or 9.01(e), terminate the DIP Commitment, in which case
the parties reserve their Rights to seek or to contest the future use of
the Lenders' Cash Collateral and the Lenders reserve their Rights to seek
to exercise the other remedies set forth in Section 9.02(a) upon order of
the Court.

     9.03. Cumulative Rights. All Rights available to Administrative Agent and
Lenders under the Loan Papers shall be cumulative of and in addition to all
other Rights granted thereto at Law or in equity, whether or not amounts
owing thereunder shall be due and payable, and whether or not
Administrative Agent or any Lender shall have instituted any suit for
collection or other action in connection with the Loan Papers.

     9.04. Waivers. The acceptance by Administrative Agent or any Lender at any
time and from time to time of partial payment of any amount owing under any
Loan Papers shall not be deemed to be a waiver of any Default or Event of
Default then existing. No waiver by Administrative Agent or any Lender of
any Default or Event of Default shall be deemed to be a waiver of any
Default or Event of Default other than such Default or Event of Default. No
delay or omission by Administrative Agent or any Lender in exercising any
Right under the Loan Papers shall impair such Right or be construed as a
waiver thereof or an acquiescence therein, nor shall any single or partial
exercise of any such Right preclude other or further exercise thereof, or
the exercise of any other Right under the Loan Papers or otherwise.

     9.05. Performance by Administrative Agent or any Lender. Should any
covenant of any Obligor fail to be performed in accordance with the terms
of the Loan Papers, Administrative Agent may, at its option, perform or
attempt to perform such covenant on behalf of such Obligor. Notwithstanding
the foregoing, it is expressly understood that neither Administrative Agent
nor any Lender assumes, and shall not ever have, except by express written
consent of Administrative Agent or such Lender, any liability or
responsibility for the performance of any duties or covenants of any
Obligor.

                                     50

<PAGE>

     9.06. Expenditures. The Borrower shall reimburse Administrative Agent and
each Lender for any reasonable sums spent by it in connection with the
exercise of any Right under Section 9.05 hereof. Such sums shall bear
interest at the lesser of (a) the Base Rate (as is defined in the
Prepetition Credit Agreement) (whether or not in effect), plus 3.00% per
annum and (b) the Highest Lawful Rate, from five days after the date any
Lender makes demand to the Borrower for reimbursement of such amount until
the date of repayment by the Borrower.

     9.07. Control. None of the covenants or other provisions contained in this
Agreement shall, or shall be deemed to, give Administrative Agent or any
Lender any Rights to exercise control over the affairs and/or management of
any Obligor, the power of Administrative Agent and each Lender being
limited to the Rights to exercise the remedies provided in this Article;
provided, however, that if Administrative Agent or any Lender becomes the
owner of any partnership, stock or other equity interest in any Person,
whether through foreclosure or otherwise, it shall be entitled to exercise
such legal Rights as it may have by being an owner of such stock or other
equity interest in such Person.

                    ARTICLE X.  THE ADMINISTRATIVE AGENT

     10.01. Authorization and Action. Each Lender hereby appoints and
authorizes Administrative Agent to take such action as Administrative Agent
on its behalf and to exercise such powers under this Agreement and the
other Loan Papers as are delegated to the Administrative Agent by the terms
of the Loan Papers, together with such powers as are reasonably incidental
thereto. As to any matters not expressly provided for by this Agreement and
the other Loan Papers (including without limitation enforcement or
collection of the Notes), Administrative Agent shall not be required to
exercise any discretion or take any action, but shall be required to act or
to refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the instructions of Majority Lenders (or all
Lenders, if required under Section 11.01 hereof), and such instructions
shall be binding upon all Lenders; provided, however, that Administrative
Agent shall not be required to take any action which exposes Administrative
Agent to personal liability or which is contrary to any Loan Papers or
applicable Law. Administrative Agent agrees to give to each Lender notice
of each notice given to it by the Borrower pursuant to the terms of this
Agreement, and to distribute to each applicable Lender in like funds all
amounts delivered to Administrative Agent by the Borrower for the
individual account of any Lender pro rata in accordance with the Applicable
Specified Percentage, as set forth in this Agreement. Functions of the
Administrative Agent are ministerial in nature and in no event shall the
Administrative Agent have a fiduciary or trustee relationship in respect of
any Lender by reason of this Agreement or any other Loan Paper.

     10.02. Administrative Agent's Reliance, Etc. Neither Administrative Agent,
nor any of its directors, officers, agents, employees, or representatives
shall be liable for any action taken or omitted to be taken by it or them
under or in connection with this Agreement or any other Loan Paper, except
for its or their own gross negligence or willful misconduct. Without
limitation of the generality of the foregoing, Administrative Agent (a) may
treat the payee of any Note as the holder thereof until Administrative
Agent receives written notice of the assignment or transfer thereof signed
by such payee and in form satisfactory to Administrative Agent; (b) may
consult with legal counsel (including counsel for the Borrower or any of
its Subsidiaries), independent public accountants, and other experts
selected by it, and shall not be liable for any action taken or omitted to
be taken in good faith by it in accordance with the advice of such counsel,
accountants, or experts; (c) makes no warranty or representation to any
Lender and shall not be responsible to any Lender for any statements,
warranties, or representations made in or in connection with this Agreement
or any other Loan Papers; (d) shall not have any duty to ascertain or to
inquire as to the performance or observance of any of the terms, covenants,
or conditions of this Agreement or any other Loan Papers on the part of the
Borrower and its Subsidiaries or to inspect the Property (including the
books and records) of the Borrower or its Subsidiaries; (e) shall not be
responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency, or value of this Agreement, any
other Loan Papers, or any other instrument or document furnished pursuant
hereto; and (f) shall incur no liability under or in respect of this
Agreement or any other Loan Papers by acting upon any notice, consent,
certificate, or other instrument or writing believed by it to be genuine
and signed or sent by the proper party or parties.

                                    51

<PAGE>

     10.03. Bank of America, N.A. and Affiliates. With respect to its DIP
Commitment, its DIP Advances, and any Loan Papers, Bank of America, N.A.
has the same Rights under this Agreement as any other Lender and may
exercise the same as though it were not Administrative Agent. Bank of
America, N.A. and its Affiliates may accept deposits from, lend money to,
act as trustee under indentures of, and generally engage in any kind of
business with, any Obligor, any Affiliate thereof, and any Person who may
do business therewith, all as if Bank of America, N.A. were not
Administrative Agent and without any duty to account therefor to any
Lender.

     10.04. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon Administrative Agent or any other
Lender, and based on the Borrower's financial statements hereof and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon
Administrative Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its
own credit decisions in taking or not taking action under this Agreement
and the other Loan Papers.

     10.05. Indemnification by Lenders. Lenders shall indemnify Administrative
Agent, pro rata in accordance with each Lender's Total Specified
Percentage, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses, or
disbursements of any kind or nature whatsoever which may be imposed on,
incurred by, or asserted against Administrative Agent in any way relating
to or arising out of any Loan Papers or any action taken or omitted by
Administrative Agent thereunder, including any negligence of Administrative
Agent; provided, however, that no Lender shall be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses, or disbursements resulting from
Administrative Agent's gross negligence or willful misconduct. Without
limitation of the foregoing, Lenders shall reimburse Administrative Agent,
pro rata in accordance with each Lender's Total Specified Percentage,
promptly upon demand for any out-of-pocket expenses (including reasonable
attorneys' fees and financial advisors' fees) incurred by Administrative
Agent in connection with the preparation, execution, delivery,
administration, modification, amendment, or enforcement (whether through
negotiation, legal proceedings or otherwise) of, or legal and other advice
in respect of rights or responsibilities under, the Loan Papers. The
indemnity provided in this Section 10.05 shall survive the termination of
this Agreement.

     10.06. Successor Administrative Agent. Administrative Agent may resign at
any time by giving written notice thereof to Lenders and the Borrower, and
may be removed at any time with or without cause by the action of all
Lenders (other than Administrative Agent, if it is a Lender). Upon any such
resignation or removal, Majority Lenders shall have the right to appoint a
successor Administrative Agent. If no successor Administrative Agent shall
have been so appointed and shall have accepted such appointment within
thirty days after the retiring Administrative Agent's giving of notice of
resignation, then the retiring Administrative Agent may, on behalf of
Lenders, appoint a successor Administrative Agent, which shall be a
commercial bank organized under the Laws of the United States of America or
of any State thereof and having a combined capital and surplus of at least
$50,000,000. Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such successor
Administrative Agent shall thereupon succeed to and become vested with all
the Rights and duties of the retiring Administrative Agent, and the
retiring Administrative Agent shall be discharged from its duties and
obligations under the Loan Papers, provided that if the retiring or removed
Administrative Agent is unable to appoint a successor Administrative Agent,
Administrative Agent shall, after the expiration of a sixty day period from
the date of notice, be relieved of all obligations as Administrative Agent
hereunder and the Lenders shall act as the Administrative Agent.
Notwithstanding any Administrative Agent's resignation or removal
hereunder, the provisions of this Article shall continue to inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement.

                         ARTICLE XI.  MISCELLANEOUS

     11.01. Amendments and Waivers. No amendment or waiver of any provision of
this Agreement or any other Loan Papers, nor consent to any departure by
the Borrower or any Obligor therefrom, shall be effective unless the same
shall be in writing and signed by the Borrower and the Administrative Agent
with the consent of the Majority Lenders, and then any such waiver or
consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, however, that no amendment,
waiver, or consent shall (and the result of action or failure to take
action shall not) unless in writing and signed by all of Lenders and
Administrative Agent, (a) increase the DIP Commitment, (b) reduce any
principal, interest, fees, or other amounts payable hereunder, or waive or
result in the waiver of any Event of Default under Section 9.01 (a) hereof,

number of Lenders required to take any action hereunder, increase the
amount of the "DIP Commitment," extend the "Maturity Date," change the
definition of "Majority Lenders," or (f) amend this Section 11.01. No
amendment, waiver, or consent shall affect the Rights or duties of
Administrative Agent under any Loan Papers, unless it is in writing and
signed by Administrative Agent in addition to the requisite number of
Lenders.

obligations as a Lender under the Loan Papers to one or more transferees
pursuant to an Assignment and Acceptance, so long as (i) each assignment
shall be pro rata with respect to both (x) the Assignor's Applicable
Specified Percentage and (y) the Assignor's Applicable Specified Percentage
(as that term is used in the Prepetition Credit Agreement) of the Domestic
Revolver Loans and the Foreign Revolver Loans of a constant, and not a
varying percentage of all Rights and obligations thereunder, (ii) each
Assignor shall obtain in each case the prior written consent of
Administrative Agent, and (iii) each Assignor shall in each case pay a
$3,500 processing fee to Administrative Agent. Within five Business Days
after Administrative Agent receives notice of any such assignment, the
Borrower shall execute and deliver to Administrative Agent, in exchange for
the Notes issued to Assignor, new Notes to the order of such Assignor and
its assignee in amounts equal to their respective Applicable Specified
Percentages of the maximum amount of the DIP Commitments. Such new Notes
shall be dated the effective date of the assignment. It is specifically
acknowledged and agreed that on and after the effective date of each
assignment, the assignee shall be a party hereto and shall have the Rights
and obligations of a Lender under the Loan Papers.

          (b) Each Lender may sell participations to one or more Persons in
all or any of its Rights and obligations under the Loan Papers; provided,
however, that (i) such Lender's obligations under the Loan Papers shall
remain unchanged, (ii) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations, (iii) such
Lender shall remain the holder of its Notes for all purposes of the Loan
Papers, (iv) the participant shall be granted the Right to vote on or
consent to only those matters described in Sections 11.01(a), (b), (c) and
(d) hereof, (v) Obligors, the Administrative Agent, and other Lenders shall
continue to deal solely and directly with such Lender in connection with
their respective Rights and obligations under the Loan Papers.

          (c) Any Lender may, in connection with any assignment or
participation, or proposed assignment or participation, disclose to the
assignee or participant, or proposed assignee or participant, any
information relating to the Borrower and its Subsidiaries furnished to such
Lender by or on behalf of the Borrower and its Subsidiaries.

          (d) Notwithstanding any other provision set forth in this Agreement,
(i) any Lender may at any time create a security interest in all or any
portion of its Rights under this Agreement (including, without limitation,
the Advances owing to it and the Notes held by it) in favor of any Federal
Reserve Bank in accordance with Regulation A of the Board of Governors of
the Federal Reserve System, and (ii) no participant of any Lender may
further assign or participate any of its interest in the Loan Papers to any
Person (except as may be required by Law or a Tribunal having authority
over such participant).

     11.05. Sharing of Payments. If, after and during the continuance of any
Event of Default, any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of any Right of set-off, or otherwise) on
account of its Advances in excess of its pro rata share of payments made by
the Obligors in accordance with such Lender's Total Specified Percentage,
such Lender shall forthwith purchase participations in Advances made by the
other Lenders as shall be necessary to share the excess payment pro rata in
accordance with each Lender's Total Specified Percentage with each of them;
provided, however, that if any of such excess payment is thereafter

                                56

<PAGE>

recovered from the purchasing Lender, its purchase from each Lender shall
be rescinded and each Lender shall repay the purchase price to the extent
of such recovery together with a pro rata share of any interest or other
amount paid or payable by the purchasing Lender in respect of the total
amount so recovered. The Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section 11.05 may, to
the fullest extent permitted by Law, exercise all its Rights of payment
(including the Right of set-off) with respect to such participation as
fully as if such Lender were the direct creditor of the Borrowers in the
amount of such participation.

     11.06. Right of Set-off. Upon the occurrence and during the continuance
of any Event of Default set forth in Sections 9.01(a), 9.01(d), 9.01(e) or
9.01(x)(i), notwithstanding the provisions of 362 of the Bankruptcy Code
and without application or motion to, or order from, the Court, each Lender
is hereby authorized (after prior written notice to the Administrative
Agent) at any time and from time to time, to the fullest extent permitted
by Law, to set-off and apply any and all deposits (general or special, time
or demand, provisional or final) at any time held and other indebtedness at
any time owing by such Lender (or any of its Affiliates) to or for the
credit or the account of the Borrower or any of its Subsidiaries against
any and all of the obligations of the Borrower or any of its Subsidiaries
now or hereafter existing under this Agreement and the other Loan Papers,
whether or not Administrative Agent or any Lender shall have made any
demand under this Agreement or the other Loan Papers, and even if such
obligations are unmatured. Each Lender shall promptly notify the Borrower
after any such set-off and application, provided that the failure to give
such notice shall not affect the validity of such set-off and application.
The Rights of each Lender under this Section 11.06 are in addition to other
Rights (including, without limitation, other Rights of set-off) which such
Lender may have.

     11.07.   Costs, Expenses, and Taxes.

          (a) Notwithstanding anything to the contrary in the Loan Papers, the
Lenders are entitled to satisfy out of the retainers paid under Section
4.01(m), (i) all costs and expenses of Administrative Agent in connection
with the preparation and negotiation of all Loan Papers, including without
limitation the reasonable fees and out-of-pocket expenses of O'Melveny &
Myers LLP, Special Counsel, Arthur Andersen, LLP, FCC counsel, PUC counsel
and local counsel, as appropriate, (ii) all costs and expenses (including
reasonable advisors' and attorneys' fees and expenses) of Administrative
Agent in connection with the administration, any interpretation, grant and
perfection of any Lien, modification, amendment, waiver, release of any
Loan Papers, restructuring or work-out or pursuant to the Chapter 11 Cases
or any other insolvency or bankruptcy proceedings (including, without
limitation, the ongoing monitoring by Administrative Agent of the Chapter
11 Cases, including attendance by Administrative Agent, the Lenders, and
their counsel and financial advisors at hearings or other proceedings and
the ongoing review of documents filed with the Court in respect thereof)
and Administrative Agent's and Lenders' interests with respect to the
Borrower and its Subsidiaries (including, without limitation, the ongoing
review of Borrower's or any Subsidiary's business assets, operations,
prospects or financial condition as Administrative Agent shall deem
necessary), the Collateral or the Obligations, (iii) all of the
out-of-pocket expenses of each of the Lenders in connection with the
modification, amendment, waiver, release of any Loan Papers, restructuring
or work-out or pursuant to the Chapter 11 Cases or any other insolvency or
bankruptcy proceedings, and (iv) all costs and expenses (including
reasonable fees and expenses of attorneys and financial advisors) of
Administrative Agent and each Lender in connection with any collection of
any portion of the Obligations or the enforcement of any Loan Papers during
the continuance of an Event of Default.

                                      57

<PAGE>

         (b) Notwithstanding anything to the contrary in the Loan Papers,
the Borrower shall pay any and all stamp, debt, and other Taxes payable or
determined to be payable in connection with any payment hereunder (other
than Taxes on the overall net income of Administrative Agent or any Lender
or franchise Taxes or Taxes on capital or capital receipts of
Administrative Agent or any Lender), or the execution, delivery, or
recordation of any Loan Papers, and agrees to save Administrative Agent and
each Lender harmless from and against any and all liabilities with respect
to, or resulting from any delay in paying or omission to pay any Taxes in
accordance with this Section 11.07, including any penalty, interest, and
expenses relating thereto. All payments by the Borrower or its Subsidiaries
under any Loan Papers shall be made free and clear of and without deduction
for any present or future Taxes (other than Taxes on the overall net income
of Administrative Agent or any Lender of any nature now or hereafter
existing, levied, or withheld, or franchise Taxes or Taxes on capital or
capital receipts of Administrative Agent or any Lender), including all
interest, penalties, or similar liabilities relating thereto. If the
Borrower or any of its Subsidiaries shall be required by Law to deduct or
to withhold any Taxes from or in respect of any amount payable hereunder
(i) the amount so payable shall be increased to the extent necessary so
that, after making all required deductions and withholdings (including
Taxes on amounts payable to Administrative Agent or any Lender pursuant to
this sentence), Administrative Agent or any Lender receives an amount equal
to the sum it would have received had no such deductions or withholdings
been made, (ii) the Borrower or any of its Subsidiaries shall make such
deductions or withholdings, and (iii) the Borrower or any of its
Subsidiaries shall pay the full amount deducted or withheld to the relevant
taxing authority in accordance with applicable Law. Without prejudice to
the survival of any other agreement of the Borrower hereunder, the
agreements and obligations of the Borrower contained in this Section 11.07
shall survive the execution of this Agreement, termination of the DIP
Commitment, repayment of the Obligations, satisfaction of each agreement
securing or assuring the Obligations and termination of this Agreement and
each other Loan Paper.

     11.08. Rate Provision. It is not the intention of any party to any Loan
Papers to make an agreement violative of the Laws of any applicable
jurisdiction relating to usury. In no event shall any Obligor or any other
Person be obligated to pay any amount in excess of the Maximum Amount. If
Administrative Agent or any Lender ever receives, collects or applies, as
interest, any such excess, such amount which would be excessive interest
shall be deemed a partial repayment of principal and treated hereunder as
such; and if principal is paid in full, any remaining excess shall be paid
to the Borrower or the other Person entitled thereto. In determining
whether or not the interest paid or payable, under any specific
contingency, exceeds the Maximum Amount, each Obligor, Administrative Agent
and each Lender shall, to the maximum extent permitted under Applicable
Laws, (a) characterize any nonprincipal payment as an expense, fee or
premium rather than as interest, (b) exclude voluntary prepayments and the
effect thereof, and (c) amortize, prorate, allocate and spread in equal
parts, the total amount of interest throughout the entire contemplated term
of the Obligations so that the interest rate is uniform throughout the
entire term of the Obligations; provided that if the Obligations are paid
and performed in full prior to the end of the full contemplated term
thereof, and if the interest received for the actual period of existence
thereof exceeds the Maximum Amount, Administrative Agent or Lenders, as
appropriate, shall refund to the Borrower the amount of such excess or
credit the amount of such excess against the total principal amount owing,
and, in such event, neither Administrative Agent nor any Lender shall be
subject to any penalties provided by any Laws for contracting for, charging
or receiving interest in excess of the Maximum Amount. This Section 11.08
shall control every other provision of all agreements among the parties to
the Loan Papers pertaining to the transactions contemplated by or contained
in the Loan Papers.

                                  58

<PAGE>

     11.09. Severability. If any provision of any Loan Papers is held to be
illegal, invalid, or unenforceable under present or future Laws during the
term thereof, such provision shall be fully severable, the appropriate Loan
Paper shall be construed and enforced as if such illegal, invalid, or
unenforceable provision had never comprised a part thereof, and the
remaining provisions thereof shall remain in full force and effect and
shall not be affected by the illegal, invalid, or unenforceable provision
or by its severance therefrom. Furthermore, in lieu of such illegal,
invalid, or unenforceable provision there shall be added automatically as a
part of such Loan Paper a legal, valid, and enforceable provision as
similar in terms to the illegal, invalid, or unenforceable provision as may
be possible.

     11.10. Exceptions to Covenants. No Obligor shall be deemed to be
permitted to take any action or to fail to take any action that is
permitted as an exception to any covenant in any Loan Papers, or that is
within the permissible limits of any covenant, if such action or omission
would result in a violation of any other covenant in any Loan Papers.

     11.11.   Intentionally Omitted.

     11.12. Counterparts. This Agreement and the other Loan Papers may be
executed in any number of counterparts, all of which taken together shall
constitute one and the same instrument. In making proof of any such
agreement, it shall not be necessary to produce or account for any
counterpart other than one signed by the party against which enforcement is
sought.

     11.13.   GOVERNING LAW; WAIVER OF JURY TRIAL.

          (a) THIS AGREEMENT AND ALL OTHER LOAN PAPERS (EXCEPT AS SUCH LOAN
PAPERS SPECIFY APPLICATION OF THE LAWS OF ANOTHER JURISDICTION) SHALL BE
DEEMED TO BE CONTRACTS MADE IN NEW YORK, NEW YORK, AND SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (EXCEPT
TO THE EXTENT THE ADMINISTRATIVE AGENT AND THE LENDERS HAVE GREATER RIGHTS
OR REMEDIES UNDER THE BANKRUPTCY CODE OR OTHER FEDERAL LAW, WHETHER AS
NATIONAL BANKS OR OTHERWISE, IN WHICH CASE SUCH CHOICE OF NEW YORK LAW
SHALL NOT BE DEEMED TO DEPRIVE ADMINISTRATIVE AGENT AND LENDERS OF ANY SUCH
RIGHTS AND REMEDIES AS MAY BE AVAILABLE UNDER THE BANKRUPTCY CODE OR OTHER
FEDERAL LAW) AND THE UNITED STATES OF AMERICA. WITHOUT EXCLUDING ANY OTHER
JURISDICTION, THE BORROWER AGREES THAT THE COURT WILL HAVE JURISDICTION
OVER PROCEEDINGS IN CONNECTION HEREWITH. TO THE MAXIMUM EXTENT PERMITTED BY
LAW, THE BORROWER HEREBY WAIVES ANY RIGHT THAT IT MAY HAVE TO A TRIAL BY
JURY OF ANY DISPUTE (WHETHER A CLAIM IN TORT, CONTRACT, EQUITY, OR
OTHERWISE) ARISING UNDER OR RELATING TO THIS AGREEMENT, THE OTHER LOAN
PAPERS, OR ANY RELATED MATTERS, AND AGREES THAT ANY SUCH DISPUTE SHALL BE
TRIED BEFORE A JUDGE SITTING WITHOUT A JURY. EACH OF THE BORROWER, THE
ADMINISTRATIVE AGENT AND EACH LENDER REPRESENTS THAT IT HAS KNOWINGLY AND
VOLUNTARILY WAIVED ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL
COUNSEL. IN THE EVENT OF LITIGATION, A COPY OF THIS AGREEMENT MAY BE FILED
AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

                                   59

<PAGE>

          (b) TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE BORROWER HEREBY
WAIVES PERSONAL SERVICE OF ANY LEGAL PROCESS UPON IT. THE BORROWER AGREES
THAT SERVICE OF PROCESS MAY BE MADE UPON IT BY REGISTERED MAIL (RETURN
RECEIPT REQUESTED) DIRECTED TO THE BORROWER AT ITS ADDRESS DESIGNATED FOR
NOTICE UNDER THIS AGREEMENT AND SERVICE SO MADE SHALL BE DEEMED TO BE
COMPLETED FIVE DAYS AFTER DEPOSIT IN THE UNITED STATES MAIL. NOTHING IN
THIS SECTION 11.12 SHALL AFFECT THE RIGHT OF ADMINISTRATIVE AGENT OR ANY
LENDER TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.

     [11.14. Limitation Of Personal Liability Notwithstanding anything herein
to the contrary, no individual employed by the Debtor Entities or DSI shall
have personal, individual liability to the Lenders arising out of this
Agreement or any actions taken pursuant hereto (including the execution and
delivery of any certificates provided for in this Agreement), absent fraud
or criminal conduct.

     11.15.   Intentionally Omitted.

     11.16.   ENTIRE AGREEMENT.  THIS AGREEMENT AND THE OTHER LOAN PAPERS
REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL
AGREEMENT OF THE PARTIES. THERE ARE NO ORAL AGREEMENTS BETWEEN THE PARTIES.

     11.17. Confidentiality. Each Lender agrees to keep information obtained
by it pursuant to the terms hereof or the terms of any other Loan Paper that
is not otherwise publicly available ("Confidential Information")
confidential in accordance with such Lender's customary procedures for
handling confidential information of this nature and in accordance with
safe and sound banking practices and agrees that it will only use such
Confidential Information in connection with the transactions contemplated
by this Agreement and not disclose any of such Confidential Information
other than (a) to such Lenders and its Affiliates' (other than an Affiliate
which is a competitor of the Borrower or its Subsidiaries) employees,

counsel (in-house and outside), accountants, consultants, representatives,
professional advisors and agents so long as such Person is advised of the
confidentiality of such Confidential Information and the limitation on its
use under this Section 11.14, and needs to have knowledge of such
Confidential Information for such limited use, (b) to regulatory officials,
and in order to comply with any Applicable Law, or other law, regulation or
judicial order, or as requested or required by bank regulators or auditors
or other governmental authorities or Tribunals, (c) as reasonably deemed
necessary in connection with any investigation, legal process or
litigation, including in connection with any proceeding or matter in the
Chapter 11 Cases to which Lenders or Administrative Agent are a party in
interest, or (d) to assignees or participants or proposed assignees or
proposed participants of all or any part of this credit facility. The
failure of any Lender to comply with the provisions of this Section 11.17
shall not affect the Obligations, or the obligation of the Borrower to
comply with the terms of this Agreement and the other Loan Papers, or the
validity of any assignment or participation granted pursuant to the terms
of this Agreement.
