                  WHEREAS, the Borrower is a direct subsidiary of Parent and the

                                   ARTICLE I.

                                   Definitions

                  Section 1.01     Definitions.

                  (a) Terms Generally. The definitions ascribed to terms in this
Agreement apply equally to both the singular and plural forms of such terms.
Whenever the context may require, any pronoun shall be deemed to include the
corresponding masculine, feminine and neuter forms.  The words "include",

<PAGE>

"includes" and "including" shall be interpreted as if followed by the phrase
"without limitation". The phrase "individually or in the aggregate" shall be
deemed to be general in scope and not to refer to any specific Section or clause
of this Agreement. All references herein to Articles, Sections, Exhibits and
Schedules shall be deemed references to Articles and Sections of, and Exhibits
and Schedules to, this Agreement unless the context shall otherwise require. The
table of contents, headings and captions herein shall not be given effect in
interpreting or construing the provisions of this Agreement. Except as otherwise
expressly provided herein, all references to "dollars" or "$" shall be deemed
references to the lawful money of the United States of America and all times
shall be deemed references to New York time.

                  (b) Accounting Terms. Except as otherwise expressly provided
herein, the term "consolidated" and all other terms of an accounting nature
shall be interpreted and construed in accordance with GAAP, as in effect on the

Consolidated Subsidiary Group and/or Loan Parties, as the case may be, shall
mean only the consolidation of the Persons indicated, as applicable, and not

used to determine compliance with any covenant set forth in Article VIII, the
Loan Parties and the Lenders agree to negotiate in good faith in an effort to
agree upon an amendment to this Agreement that will permit compliance with such
covenant to be determined by reference to GAAP as so changed while affording the
Lenders and the Consolidated Group the rights and obligations intended to be
afforded by such covenant prior to such change (it being understood, however,
that such covenant shall remain in full force and effect in accordance with its
existing terms unless and until such amendment shall become effective).

         shall not exceed the Total Revolving Credit Commitment then in effect.

                  (ii) If any event described in Section 8.01(o) results in net
         proceeds (whether in the form of insurance proceeds, condemnation award
         or otherwise), the Borrower shall within twelve (12) months thereafter
         apply such net proceeds to the prepayment of the Facilities, unless
         within such twelve (12) month period the Loan Parties utilize such net
         proceeds to acquire Telecommunications Assets, provided that (A) if
         such Telecommunications Assets consist of Capital Stock of any Person
         engaged primarily in the Telecommunications Business, such Person shall
         be a Restricted Subsidiary or a Person that becomes a Restricted
         Subsidiary and (B) such net proceeds shall not be used to acquire
         Telecommunications Assets if an Event of Default shall have occurred
         and be continuing.

                  (iii) If the Loan Parties sell, transfer, lease or otherwise
         dispose of assets or properties not in the ordinary course of business
         in a sale permitted hereunder for Net Available Cash other than
         Unrestricted Proceeds in excess of $20.0 million in one or more
         transactions in a fiscal year, the Borrower within twelve (12) months
         thereafter shall apply such Net Available Cash to the prepayment of the
         Facilities, unless within such twelve (12) month period the Loan
         Parties utilize such Net Available Cash to acquire Telecommunications
         Assets, provided that (A) if such Telecommunications Assets consist of
         Capital Stock of any Person engaged primarily in the Telecommunications
         Business, such Person shall be a Restricted Subsidiary or a Person that
         becomes a Restricted Subsidiary and (B) such Net Available Cash shall
         not be used to acquire Telecommunications Assets if an Event of Default
         shall have occurred and be continuing.

                  (iv) Prepayments under subsections (ii) and (iii) above shall
         (A) first be applied ratably to the Term Loans and ratably to the
         scheduled installments of principal of the Term Loans, in each case in
         accordance with the respective principal amounts thereof and (B) to the

                                       37

<PAGE>

         extent the Term Loans have been paid in full, to the Revolving Credit
         Loans.

                  (d) Prepayment Fee. In the event the Borrower prepays the Term
Loan B Loan, the Borrower shall pay, for the account of the Term Loan B Lenders,
a prepayment fee equal to (i) 3% of the principal amount prepaid if prepayment
occurs between the Effective Date and the first anniversary of the Effective
Date, (ii) 2% of the principal amount prepaid if prepayment occurs between the
first anniversary of the Effective Date and the second anniversary of the
Effective Date, and (iii) 1% of the principal amount prepaid if prepayment
occurs between the second anniversary of the Effective Date and the third
anniversary of the Effective Date. Prepayments of the Term Loan B Loan made
after the third anniversary of the Effective Date are not subject to this
prepayment fee.

                  Section 2.07     Letters of Credit.

                  (a) Letters of Credit. Prior to the Revolving Credit
Commitment Termination Date, and subject to the terms and conditions of this
Agreement, from time to time, the Borrower may request that the L/C Issuer issue
under this Agreement, and the L/C Issuer shall upon such request of the Borrower
and upon the satisfaction or waiver of each of the conditions contained in
Article VII applicable thereto, issue for the account of the Borrower, one or
more letters of credit (each, a "Letter of Credit") in the L/C Issuer's
then-customary form; provided, that the L/C Issuer shall not issue any Letter of
Credit: (i) if, after giving effect to such issuance, the sum of the aggregate
amount of the L/C Obligations of all the Revolving Credit Lenders then
outstanding and the aggregate amount of Revolving Credit Loans of all the
Revolving Credit Lenders then outstanding would exceed the Total Revolving
Credit Commitment then in effect; (ii) having a stated amount of less than
$10,000; (iii) having an expiration date later than the Business Day
four Business Days prior to the Revolving Credit Commitment Termination Date; or
(iv) if, after giving effect to such issuance, the aggregate amount of L/C
Obligations of all the Revolving Credit Lenders then outstanding would exceed
$75.0 million.

                  (b) Procedure for Obtaining Letter of Credit. The Borrower may
request that the L/C Issuer issue a Letter of Credit pursuant to Section 2.07(a)
by giving a L/C Request to the Administrative Agent in writing substantially in
the form of not later than 12:00 P.M. (noon) on the fourth Business Day prior to
the proposed date of issuance of the Letter of Credit. Upon receipt of any L/C
Request, the Administrative Agent shall forthwith give notice to each Revolving
Credit Lender of the substance thereof. On the date specified by the Borrower in
such notice and upon fulfillment of the applicable conditions set forth in this
Section 2.07 and Article VII or the waiver thereof by the Revolving Credit
Lenders, the L/C Issuer will issue such Letter of Credit in the form specified
in such L/C Request.

                  (c) Participation by Revolving Credit Lenders. Immediately
upon the issuance of a Letter of Credit, each Revolving Credit Lender other than
the L/C Issuer shall be deemed to, and hereby agrees to, have irrevocably and
unconditionally purchased from the L/C Issuer a participation in such Letter of
Credit and each drawing thereunder in an amount equal to such Revolving Credit
Lender's Pro Rata Share of the maximum amount which is or at any time may become
available to be drawn thereunder.

                                       38

<PAGE>

                  (d) Drawings and Reimbursement. (i) In the event of any
         request for a drawing under any Letter of Credit by the beneficiary
         thereof, the L/C Issuer shall notify the Borrower and the
         Administrative Agent as promptly as practicable following receipt of
         such request, and the Borrower shall reimburse the L/C Issuer on or
         prior to the third Business Day after the day on which such drawing is
         honored in an amount in immediately available funds equal to the amount
         of such drawing.

                  (ii) If the Borrower shall fail to reimburse the L/C Issuer in
         an amount equal to the amount of any drawing honored by the L/C Issuer
         under a Letter of Credit, then the L/C Issuer shall promptly notify
         each Revolving Credit Lender of the unreimbursed amount of such drawing
         and of such Revolving Credit Lender's respective participation therein.
         Not later than 2:00 P.M. on the Business Day after the date notified by
         the L/C Issuer or if the Revolving Credit Lenders are notified by the
         L/C Issuer prior to 11:00 A.M. on the date so notified, each Revolving
         Credit Lender shall make available to the L/C Issuer in immediately
         available funds at the aforementioned office of the L/C Issuer in The
         City of New York an amount equal to its respective participation. For
         so long as any Revolving Credit Lender fails so to fund its
         participation in any such Letter of Credit, the amount of such
         participation shall be deemed, for purposes of determining the Required
         Lenders, to be subtracted from such Revolving Credit Lender's L/C
         Obligations and added to the L/C Issuer's L/C Obligations. In the event
         that any Revolving Credit Lender fails to make available to the L/C
         Issuer on such Business Day the amount of such Revolving Credit
         Lender's participation in such Letter of Credit as provided in this
         Section 2.07(d), the L/C Issuer shall be entitled to recover such
         amount on demand from such Revolving Credit Lender, together with
         interest thereon at a rate per annum equal to (A) from (and including)
         such Business Day to (and including) the third Business Day
         thereafter, the Federal Funds Rate, and (B) from (but excluding) such
         third Business Day, the sum of 2% and the Federal Funds Rate. The L/C
         Issuer shall distribute to each Revolving Credit Lender that has paid
         all amounts payable by it under this Section 2.07 with respect to any
         Letter of Credit such Lender's Pro Rata Share of all payments received
         by the L/C Issuer from the Borrower in reimbursement of drawings
         honored by the L/C Issuer under such Letter of Credit when such
         payments are received.

                   (iii) The obligation of the Borrower to reimburse the L/C
         Issuer for drawings made under the Letters of Credit and the
         obligations of the Revolving Credit Lenders under Section 2.07(d)(ii)
         shall be unconditional and irrevocable and shall be paid strictly in
         accordance with the terms of the Credit Documents under all
         circumstances, including the following circumstances:

                        (A)   any lack of validity or enforceability of any
                  Letter of Credit;

                        (B) the existence of any claim, set-off, defense or
                  other right which the Borrower or any Affiliate of the
                  Borrower may have at any time against a beneficiary or any
                  transferee of any Letter of Credit (or any Persons for whom
                  any such beneficiary or transferee may be acting), the L/C
                  Issuer, any Revolving Credit Lender or any other Person,
                  whether in connection with any Credit Document, any
                  transaction contemplated thereby or any unrelated transaction;

                                       39
<PAGE>

                        (C) any draft, demand, certificate or any other document
                  presented under any Letter of Credit proving to be forged,
                  fraudulent, invalid or insufficient in any respect or any
                  statement therein being untrue or inaccurate in any respect;

                        (D) payment by the L/C Issuer under any Letter of Credit
                  against presentation of a demand, draft or certificate or
                  other document that does not comply with the terms of the
                  Credit Documents;

                        (E)   any other circumstance or happening whatsoever,
                  which is similar to any of the foregoing; or

                        (F) the fact that a Default or Event of Default shall
                  have occurred.

                  (e) Security Deposit. If a Default or Event of Default shall
have occurred and be continuing, the Administrative Agent may deposit funds in
an interest-bearing account as agreed to between the Administrative Agent, the
L/C Issuer and the Borrower to secure payment to the beneficiary of any
outstanding Letter of Credit. Any funds so deposited shall be paid to the
beneficiary of such Letter of Credit if all conditions to such payment are
satisfied or returned to the L/C Issuer for distribution to the Revolving Credit
Lenders (or, if all obligations under this Agreement shall have been
indefeasibly paid in full, to the Borrower), if no payment to the beneficiary
has been made and the final date available for drawings under such Letter of
Credit has passed. Each payment or deposit of funds by the L/C Issuer as
provided in this paragraph shall be treated for all purposes of this Agreement
as a drawing duly honored by the L/C Issuer under the related Letter of Credit.

                                  ARTICLE III.

                                Interest and Fees

                  Section 3.01 Interest Rate Determination; Conversion. (a)
Except to the extent that the Borrower shall request, in a Borrowing Request or
in a Conversion Request, that Revolving Credit Loans (or portions thereof) bear
interest as Eurodollar Loans, Revolving Credit Loans shall bear interest as ABR
Loans.

                  (b) The Borrower may request, by giving a Conversion Request
to the Administrative Agent, by telephone, telecopy or in writing not later than
12:00 P.M. (noon) (if not in writing, to be so confirmed in substantially the
form of Exhibit 3.01(b) not later than 2:00 P.M.), on the third Business Day
prior to the requested Conversion Date, that all or portions of the outstanding
Loans, in the aggregate principal amount of $5.0 million or in integral
multiples of $1.0 million in excess thereof (or, if the aggregate principal
amount of outstanding Loans is less than $5.0 million, then all such lesser
amount), bear interest from and after the Conversion Date as either ABR Loans or
Eurodollar Loans; provided, however, that during the continuance of any Default
or Event of Default that shall have occurred, no Loan (or portion thereof) may
be converted into Eurodollar Loans. Upon receipt, the Administrative Agent
forthwith shall give notice to each Lender of the substance of each Conversion
Request. Upon payment by the Borrower of the amounts, if any, required by

                                       40

<PAGE>

Section 4.03, on the Conversion Date the Loans or portions thereof as to which
the Conversion Request was made shall commence to accrue interest in the manner
selected by the Borrower therein.

                  Section 3.02 Interest on ABR Loans. Each ABR Loan shall bear
interest from the date made until the date repaid, or if converted into a
Eurodollar Loan to (but excluding) the first day of any relevant Interest
Period, as the case may be, payable in arrears on the last day of each calendar
quarter of each year, commencing with the first such date after the Effective
Date, and on the date such Loan is repaid, at a rate per annum equal to the sum
of (a) the Alternate Base Rate in effect from time to time, and (b) the
Applicable Margin in effect from time to time.

                  Section 3.03 Interest on Eurodollar Loans. (a) Each Eurodollar
Loan shall bear interest from the date made until the date repaid or converted
to an ABR Loan, payable in arrears, with respect to Interest Periods of three
months or less, on the last day of such Interest Period, and with respect to
Interest Periods longer than three months, on the day which is three months
after the commencement of such Interest Period and on the last day of such
Interest Period, at a rate per annum equal to the sum of (i) the Applicable
Margin as of the first day of the Interest Period, in the case of Eurodollar
Revolving Loans or Eurodollar Term Loans and (ii) LIBOR.

                  (b) Each Eurodollar Loan shall become an ABR Loan at the end
of the Interest Period therefor unless (i) there shall not have occurred and be
continuing a Default or Event of Default or (ii) not later than the third
Business Day prior to the last day of such Interest Period, the Borrower shall
have delivered to the Administrative Agent (x) an irrevocable written election
of the subsequent Interest Period therefor, in which case such Eurodollar
Revolving Loan shall remain outstanding as a Eurodollar Loan, or (y) a
Conversion Request with respect thereto, in which case such Eurodollar Revolving
Loan shall be converted in accordance with Section 3.01(b).

                  (c) If, during any period, a Lender shall be required to
maintain reserves against "eurocurrency liabilities" in accordance with Federal
Reserve Board Regulation D (or any successor regulation), the Borrower shall pay
additional interest during such period on each outstanding Eurodollar Loan of
such Lender (contemporaneously with each interest payment due thereon commencing
with the first such payment due at least two Business Days after receipt of the
notice referred to in the next sentence) at a rate per annum up to but not
exceeding the marginal rate determined by the following formula:

                  LIBOR
     ----------------------------------
                                          --      LIBOR.
      1 - Eurodollar Reserve Percentage

Each Lender shall promptly notify the Borrower, with a copy to the
Administrative Agent, upon becoming aware that the Borrower may be required to
make a payment of additional interest to such Lender. When requesting payment
pursuant to this Section 3.03(c), a Lender shall provide to the Borrower, with a
copy to the Administrative Agent, a certificate, signed by an officer of such
Lender setting forth, in reasonable detail, the basis of such claim, the amount
required to be paid by the Borrower to such Lender and the computations made by

                                       41

<PAGE>

such Lender to determine such amount. Absent manifest error, such certificate
shall be binding as to the amounts of additional interest owing in respect of
such Lender's Eurodollar Loans. Any Lender that gives notice under this Section
3.03(c) shall promptly withdraw such notice (by written notice of withdrawal
given to the Administrative Agent and the Borrower) whenever such Lender is no
longer required to maintain such reserves or the circumstances giving rise to
such notice shall otherwise cease.

                  Section 3.04 Interest on Overdue Amounts and During Any Event
of Default. Anything herein to the contrary notwithstanding, (a) during the
continuance of an Event of Default under Sections 9.01(a) or 9.01(b), all
overdue amounts hereunder (including principal, interest and fees), and (b) upon
any other Event of Default with the consent of the Required Lenders, each Loan
shall bear interest, payable on demand, at a rate per annum equal to the sum of
(i) 2% and (ii) the rate then applicable, in the case of Eurodollar Loans, until
the end of the current Interest Period therefor, and thereafter the rate of
interest applicable to ABR Loans, changing as and when such rate shall change.

                  Section 3.05 Day Counts. Interest on ABR Loans shall be
calculated on the basis of (a) a 365- or, if applicable, a 366-day year for the
actual number of days elapsed for so long as interest is determined pursuant to
clause (1) of the definition of "Alternate Base Rate" and (b) a 360-day year for
the actual number of days elapsed otherwise. Interest on all other Loans, and
all fees shall be calculated on the basis of a 360-day year for the actual
number of days elapsed.

                  Section 3.06 Maximum Interest Rate. (a) Nothing in this
Agreement shall require the Borrower to pay interest at a rate exceeding the
maximum rate permitted by applicable law. Neither this Section nor Section 13.01
is intended to limit the rate of interest payable for the account of any Lender
to the maximum rate permitted by the laws of the State of New York (or any other
applicable law) if a higher rate is permitted with respect to such Lender by
supervening provisions of United States federal law.

                  (b) If the amount of interest payable for the account of any
Lender on any interest payment date in respect of the immediately preceding
interest computation period, computed pursuant to this Article III, would exceed
the maximum amount permitted by applicable law to be charged by such Lender, the
amount of interest payable for its account on such interest payment date shall
automatically be reduced to such maximum permissible amount.

                  (c) If the amount of interest payable for the account of any
Lender in respect of any interest computation period is reduced pursuant to
Section 3.06(b) and the amount of interest payable for its account in respect of
any subsequent interest computation period would be less than the maximum amount
permitted by law to be charged by such Lender, then the amount of interest
payable for its account in respect of such subsequent interest computation
period shall be automatically increased to such maximum permissible amount;
provided that at no time shall the aggregate amount by which interest paid for
the account of any Lender has been increased pursuant to this Section 3.06(c)
exceed the aggregate amount by which interest paid for its account has
theretofore been reduced pursuant to Section 3.06(b).

                  Section 3.07     Fees.

                  (a) The Commitment Fee. The Borrower agrees to pay to the
Administrative Agent, for the respective accounts of the Lenders, on the last
day of each calendar quarter of each year, commencing with the first such day
after the Effective Date, and on the Revolving Credit Commitment Termination
Date (or other date on which the Commitment shall terminate), a fee (the
"Commitment Fee") computed by applying (i) the applicable Commitment Fee
percentage per annum set forth below (such applicable Commitment Fee being based
on the fraction of the Total Commitment that is undrawn) to (ii) the average
portion of the Total Commitment undrawn during the calendar quarter:

                                    Average Portion of
      Commitment Fee               Total Commitment Undrawn
      --------------               ------------------------
          1.25%                             >=2/3

          0.75%                             <1/3

                  (b) Letter of Credit Fees. In lieu of any letter of credit
commissions or fees provided for in any letter of credit application (other than
documentary and processing charges referred to in clause (iv) below), the
Borrower agrees to pay to the L/C Issuer in funds immediately available at the
office of the L/C Issuer specified in Section 13.07(a) the following
fees and other amounts with respect to each outstanding Letter of Credit
(collectively, the "Letter of Credit Fees"):

                  (i) an administrative fee equal to 0.10% per annum on the
         daily amount stated to be available from time to time for drawing under
         such Letter of Credit from (and including) the date of issuance until
         (but excluding) the expiration date of such Letter of Credit, payable
         to the L/C Issuer in arrears on the last day of each calendar quarter,
         commencing on the first such date after the Borrowing Date, and on such
         expiration date;

                  (ii) a letter of credit fee, at a rate per annum equal to the
         Applicable Margin from time to time in effect for Eurodollar Revolving
         Loans, on the daily amount stated to be available from time to time for
         drawing under such Letter of Credit from (and including) the date of
         issuance until (but excluding) the expiration date of such Letter of
         Credit payable to the L/C Issuer for the account of the Revolving
         Credit Lenders in arrears on the last day of each calendar quarter,
         commencing on the first such date after the Borrowing Date, and on such
         expiration date;

                  (iii) with respect to drawings made thereunder, interest,
         payable on demand to the L/C Issuer (if applicable, for the benefit of
         the Lenders that have funded a participation therein pursuant to
         Section 2.07(d)), on the amount paid by the L/C Issuer in respect of
         each such drawing from (and including) the date of the drawing to (but
         excluding) the date such amount is reimbursed by the Borrower, at a
         rate per annum equal to (A) from (and including) the date of such
         drawing to (and including) the third Business Day after the date of
         such drawing, the rate of interest then applicable to ABR Revolving
         Loans, changing as and when said rate shall change, and (B) from (but

                                       43

<PAGE>

         excluding) the third Business Day after the date of such drawing, the
         sum of (x) 2% and (y) the rate specified in clause (A); and

                  (iv) with respect to the issuance, amendment or transfer of
         such Letter of Credit and each drawing made thereunder, customary
         documentary and processing charges payable to the L/C Issuer in
         accordance with the L/C Issuer's standard schedule for such charges in
         effect at the time of such issuance, amendment, transfer or drawing, as
         the case may be.

Promptly upon receipt by the L/C Issuer of any amount described in clause (ii)
or (iii) of this Sec tion 3.07(b), the L/C Issuer shall distribute to each
Revolving Credit Lender that has paid all amounts payable by it under Section
2.07(d) such Revolving Credit Lender's ratable share of such amount. Amounts
payable under clauses (i) and (iv) of this Section 3.07(b) shall be retained by
the L/C Issuer.

                                   ARTICLE IV.

                            Disbursement and Payment

                  Section 4.01     Disbursement.  (a)  Each Loan shall be made
by the relevant Lender from such Lender's branch or Affiliate identified as its
Applicable Lending Office.

                  (b) The failure of any Lender to make any Loan to be made by
it on the Borrowing Date therefor shall not relieve any other Lender of its
obligation to make its Loan or Loans on such date, but neither any Lender nor
the Administrative Agent shall be responsible for the failure of any other
Lender to make a Loan to be made by such other Lender.

                  (c) The Administrative Agent may, but shall not be required
to, advance on behalf of any Lender the amount of such Lender's Loans to be made
on a Borrowing Date, unless such Lender shall have notified the Administrative
Agent prior to such Borrowing Date that it does not intend to make such Loans on
such date. If the Administrative Agent makes any such advance, the
Administrative Agent shall be entitled to recover the amount so advanced on
demand from the Lender on whose behalf such advance was made and, if such Lender
does not pay the Administrative Agent the amount of such advance on demand, the
Borrower agrees promptly to repay such amount to the Administrative Agent. Until
such amount is repaid to the Administrative Agent by such Lender or the
Borrower, such advance shall be deemed for all purposes to be a Loan made on
such Borrowing Date by the Administrative Agent. The Administrative Agent shall
be entitled to recover from the Lender or the Borrower, as the case may be,
interest on the amount advanced by it for each day from the Borrowing Date
therefor until repaid to the Administrative Agent, at a rate per annum equal to
the Federal Funds Rate until the third Business Day after the date of the
advance and, thereafter, at the rate per annum equal to the relevant rate on
Loans made on the relevant Borrowing Date.

                  Section 4.02 Method and Time of Payments; Sharing among
Lenders. (a) All funds received by the Administrative Agent for the account of
the Lenders in respect of payments made by the Borrower under, or from any other
Person on account of, any Credit Document shall be distributed promptly by the

                                       44

<PAGE>

Administrative Agent among the Lenders, in like funds as received, ratably in
proportion to their respective interests therein. Each payment of the Commitment
Fee and each reduction of Revolving Credit Commitments or Term Loan Commitments
shall be apportioned among the Revolving Credit Lenders, Term Loan A Lenders and
Term Loan B Lenders, as the case may be, in proportion to each such Lender's Pro
Rata Share.

                  (b) All payments by the Borrower hereunder shall be made
without set-off or counterclaim to the Administrative Agent, for its account or
for the account of the Lender or Lenders entitled thereto, as the case may be,
in dollars and in immediately available funds at the office of the
Administrative Agent theretofore designated in writing to the Borrower not later
than 11:00 A.M., on the date when due or, in the case of payments pursuant to
Sections 2.04, 4.03, 4.04, 4.06 or payments otherwise specified as payable upon
demand, forthwith upon written demand therefor.

                  (c) Whenever any payment from the Borrower shall be due on a
day that is not a Business Day, the date of payment thereof shall be extended to
the next succeeding Business Day. If the date for any payment of principal is
extended by operation of law or otherwise, interest thereon shall be payable for
such extended time.

                  (d) Unless the Administrative Agent shall have received notice
from the Borrower prior to the date on which any payment from the Borrower is
due that the Borrower will not make such payment in full, the Administrative
Agent may assume that the Borrower has made such payment in full to the
Administrative Agent on such date and the Administrative Agent may, in reliance
upon such assumption, but shall not be obligated to, cause to be distributed to
each Lender on such due date an amount equal to the amount then due to such
Lender. If and to the extent that the Borrower shall not have so made such
payment, each Lender shall repay to the Administrative Agent forthwith on demand
such amount distributed to such Lender together with interest thereon, for each
day from the date such amount is distributed to such Lender until the date such
Lender repays such amount to the Administrative Agent, at the Federal Funds
Rate.

                  (e) If any Lender shall receive from the Borrower or any other
Person any amount owing under any Credit Document (whether received pursuant to
the exercise of any right of set-off, banker's lien, realization upon any
security held for or appropriated to such obligation or otherwise) other than in
proportion to such Lender's ratable share thereof, then such Lender shall
purchase from each other Lender a participating interest in so much of the other
Lenders' Loans as shall be necessary in order that each Lender shall share such
payment with each of the other Lenders in proportion to each Lender's ratable
share; provided that nothing herein contained shall obligate any Lender to apply
any set-off or banker's lien or collateral security permitted hereby first to
the obligations of the Borrower hereunder if the Borrower is obligated to such
Lender pursuant to other loans or notes. If any purchasing Lender shall be
required to return any excess payment received by it, such participation shall
be rescinded and the purchase price restored to the extent of such return, but
without interest.

                  Section 4.03 Compensation for Losses. (a) If (i) the Borrower
prepays Loans, or a Conversion Date occurs (other than pursuant to Section
4.05), other than on the last day of the relevant Interest Period, (ii) the

                                       45

<PAGE>

Borrower revokes any Borrowing Request, (iii) Loans (or portions thereof) are
converted into ABR Loans pursuant to Section 4.05 or (iv) Loans (or portions
thereof) shall become or be declared to be due prior to the scheduled maturity
thereof, then the Borrower shall pay to each Lender an amount that will
compensate such Lender for any loss (other than lost profit) or premium or
penalty Incurred by such Lender as a result of such prepayment, conversion,
declaration or revocation in respect of funds obtained for the purpose of making
or maintaining such Lender's Loans, or any portion thereof.

                  (b) If requested by the Borrower, in connection with a payment
due pursuant to this Section 4.03, a Lender shall provide to the Borrower, with
a copy to the Administrative Agent, a certificate setting forth in reasonable
detail the amount required to be paid by the Borrower to such Lender and the
computations made by such Lender to determine such amount. In the absence of
manifest error, such certificate shall be prima facie evidence as to the amount
required to be paid.

                  Section 4.04     Withholding and Additional Costs.

                  (a) Withholding. (i) All payments under this Agreement and
         under the Notes (including payments of principal and interest) shall be
         payable to each Lender free and clear of any and all present and future
         taxes, levies, imposts, duties, deductions, withholdings and similar
         charges other than Excluded Taxes (collectively, "Taxes"). If any Taxes
         are required to be withheld or deducted from any amount payable under
         this Agreement, then the amount payable under this Agreement shall be
         increased to the amount which, after deduction from such increased
         amount of all Taxes required to be withheld or deducted therefrom, will
         yield to such Lender the amount stated to be payable under this
         Agreement. The Borrower shall also hold each Lender harmless and
         indemnify it against any transfer taxes, documentary taxes, stamp or
         other taxes, assessments or charges made by any Governmental Authority
         with respect to the preparation, execution, delivery, recording,
         performance or enforcement of the Credit Documents (all of which shall
         be included within "Taxes"). If any of the Taxes specified in this
         Section 4.04(a) are paid by any Lender, the Borrower shall, upon
         written demand of such Lender, promptly reimburse such Lender for such
         payments, together with any interest and penalties, incurred in
         connection therewith. The Borrower shall deliver to the Administrative
         Agent certificates or other valid vouchers (or copies thereof) for all
         Taxes or other charges deducted from or paid with respect to payments
         made by the Borrower hereunder. Notwithstanding the foregoing, the
         Borrower shall be entitled, to the extent required to do so by law, to
         deduct or withhold (and shall not be required to make payments as
         otherwise required by this Section 4.04(a) on account of such
         deductions or withholdings) (i) Excluded Taxes and (ii) income or other
         similar taxes imposed by the United States of America on interest, fees
         or other amounts payable hereunder for the account of any Lender (other
         than a Lender (A) that is not a U.S. Person for United States federal
         income tax purposes and (B) that has the Prescribed Forms on file with
         the Borrower); provided that, if the Borrower shall so deduct or
         withhold any such taxes, the Borrower shall provide a statement to the
         Administrative Agent and such Lender, setting forth the amount of such
         taxes so deducted or withheld, the applicable rate and any other
         information or documentation which such Lender may reasonably request
         for assisting such Lender to obtain any allowable credits or deductions
         for the taxes so deducted or withheld in the jurisdiction or
         jurisdictions in which such Lender is subject to tax.

                                       46

<PAGE>

                  (ii) Each Lender that is not incorporated under the laws of
         the United States of America or a state thereof shall deliver to the
         Borrower and the Administrative Agent two duly completed copies of
         United States Internal Revenue Service Form 1001 or W-8BEN or 4224 or
         W-8ECI (or any successor form or forms), certifying in either case that
         such Lender is entitled to receive payments under this Agreement
         without deduction or withholding of any United States federal income or
         other similar taxes ("Prescribed Forms") and upon such certification by
         such Lender, no withholding or backup withholding of any U.S. federal
         income or other similar taxes shall be made to the extent deduction or
         withholding of such taxes is not required as a result of such filing of
         such Prescribed Forms. Each Lender that so delivers such Prescribed
         Forms further undertakes to deliver to the Borrower and the
         Administrative Agent two additional copies of such Prescribed Forms on
         or before the date that such Prescribed Forms expire or become
         obsolete or after the occurrence of any event requiring a change in
         the most recent Prescribed Forms so delivered by it, and such
         amendments thereto or extensions or renewals thereof as may be
         reasonably requested by the Borrower or the Administrative Agent, in
         each case certifying that such Lender is entitled to receive payments
         under this Agreement without deduction or withholding of any United
         States federal income or other similar taxes, unless an event
         (including without limitation any change in treaty, law or regulation)
         has occurred prior to the date on which any such delivery would
         otherwise be required which renders all such Prescribed Forms
         inapplicable or which would prevent such Lender from duly completing
         and delivering Prescribed Forms with respect to it and such Lender
         advises the Borrower and the Administrative Agent that it is not
         capable of receiving payments without any deduction or withholding of
         United States federal income or other similar tax. If any Lender that
         is not incorporated under the laws of the United States of America or
         a state thereof fails to comply with the provisions of this Section
         (other than a failure resulting from any such change in law after the
         Effective Date), the Borrower and/or the Administrative Agent may, as
         required by law, deduct and withhold United States federal income or
         other similar tax payments from payments to such Lender under this
         Agreement (and shall not be required to make payments as otherwise
         required by this Section 4.04(a) on account of such deductions or
         withholding.)

                  (iii) In the event that an additional payment is required to
         be made under Section 4.04(a) for the account of the Administrative
         Agent or any Lender, the Administrative Agent and such Lender shall
         undertake best efforts (consistent with any applicable law) to fulfill
         any reporting, registration or similar requirements prescribed by the
         relevant authority imposing any withholding or deduction on the amounts
         payable by the Borrower under this Agreement or under the notes as a
         prerequisite to a reduction or elimination of such withholding or
         deduction.

                  (iv) In the event that an additional payment is made under
         this Section 4.04(a) for the account of the Administrative Agent or any
         Lender and the Administrative Agent or such Lender has finally and
         irrevocably received or been granted a credit against or release or
         remission for, or repayment of, any tax paid or payable by it in
         respect of or calculated with reference to the deduction or withholding
         giving rise to such payment, the Administrative Agent or such Lender

                                       47

<PAGE>

         shall, to the extent that it determines that it can do so without
         prejudice to the retention of the amount of such credit, relief,
         remission or repayment, pay to the Borrower such amount (net of any
         administrative costs relating to the receipt and calculation of each
         credit) as the Administrative Agent or such Lender shall have
         determined to be attributable to such deduction or withholding and
         which will leave the Administrative Agent or such Lender (after such
         payment) in no worse position than it would have been in if the
         Borrower had not been required to make such deduction or withholding.

                  (b)   Additional Costs.  Subject to Sections 4.04(c) and (d):

                  (i) Without duplication of any amounts payable described in
         Section 3.03(c), 4.03 or 4.04(a) or 4.04(b)(ii), if after the date
         hereof any change in any law or regulation or in the interpretation
         thereof by any court or administrative or Governmental Authority
         charged with the administration thereof or the enactment of any law or
         regulation shall either (1) impose, modify or deem applicable any
         reserve, special deposit or similar requirement against any Lender's
         Commitment or Loans or (2) impose on any Lender (or such Lender's
         Applicable Lending Office) any other condition regarding this
         Agreement, its Commitment or the Loans and the result of any event
         referred to in clause (1) or (2) shall be to increase the cost to such
         Lender (or such Lender's Applicable Lending Office) of maintaining its
         Commitment or any Eurodollar Loans made by such Lender (which increase
         in cost shall be calculated in accordance with such Lender's
         reasonable averaging and attribution methods), excluding for purposes
         of this Section 4.04(b) any such increased costs resulting from (i)
         Taxes (as to which Section 4.04(a) shall govern) and (ii) changes in
         the basis of taxation of Excluded Taxes, by an amount which such
         Lender deems to be material, then, upon demand by such Lender, the
         Borrower shall pay to such Lender an amount equal to such increase in
         cost; and

                  (ii) Without duplication of any amounts payable described in
         Section 3.03(c), 4.03, 4.04(a) or 4.04(b)(i), if any Lender shall have
         determined that after the date hereof the adoption of any applicable
         law, rule, regulation or guideline regarding capital adequacy, or any
         change therein after the date hereof, or any change after the date
         hereof in the interpretation or administration thereof by any
         Governmental Authority, central bank or comparable agency charged with
         the interpretation or administration thereof or compliance by such
         Lender (or such Lender's Applicable Lending Office) with any request or
         directive regarding capital adequacy (whether or not having the force
         of law) of any such authority, central bank or comparable agency issued
         after the date hereof, has or would have the effect of reducing the
         rate of return on capital for such Lender (or such Lender's Applicable
         Lending Office) or any corporation controlling such Lender as a
         consequence of its obligations under this Agreement to a level below
         that which such Lender (or such Lender's Applicable Lending Office) or
         such corporation could have achieved but for such adoption, change or
         compliance (taking into consideration such Lender's (or such Lender's
         Applicable Lending Office) or such corporation's policies with respect
         to capital adequacy), then from time to time, upon demand by such
         Lender, then the Borrower shall pay to such Lender such additional
         amount or amounts as will compensate such Lender (or such Lender's
         Applicable Lending Office) or such corporation for such reduction.

                                       48

<PAGE>

                  (c) Lending Office Designations. Before making any demand for
payment pursuant to this Section 4.04, each Lender shall (i) if possible,
designate a different Applicable Lending Office if such designation will avoid
the need for giving such notice and will not, in the reasonable judgment of such
Lender, be otherwise disadvantageous to such Lender and (ii) take such other
action reasonably available to such Lender, at the Borrower's expense, if such
action will avoid the need for giving such notice and will not, in the
reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

                  (d)   Certificate, Etc.  In connection with any demand for
payment pursuant to this Section 4.04, a Lender shall provide to the Borrower,
with a copy to the Administrative Agent, a certificate setting forth in
reasonable detail the basis for such demand, the amount required to be paid by
the Borrower to such Lender, the computations made by such Lender to determine
such amount and satisfaction of the conditions set forth in the next sentence.
Anything to the contrary herein notwithstanding, no Lender shall have the right
to demand any payment or compensation under this Section 4.04 (i) with respect
to any period more than 90 days prior to the date it has made a demand pursuant
to this Section 4.04 or (ii) to the extent that such Lender determines in good
faith that the interest rate or margin on the relevant Loans appropriately
accounts for any increased cost or reduced rate of return. In the absence of
manifest error, the certificate referred to above shall be prima facie evidence
of the amount required to be paid.

                  Section 4.05 Illegality. If at any time any Lender shall
determine in good faith (which determination shall be conclusive) that the
making or maintenance of all or any part of such Lender's Eurodollar Loans has
been made unlawful because of compliance by such Lender in good faith with any
law or guideline or interpretation or administration thereof by any Governmental
Authority charged with the interpretation or administration thereof or with any
request or directive of such body (whether or not having the effect of law) or
because dollar deposits in the amount and requested maturity of such Eurodollar
Loans are not available to such Lender in the London eurodollar interbank market
then the Administrative Agent, upon notice to it of such determination by such
Lender, shall promptly advise the other Lenders and the Borrower thereof. Upon
such date as shall be specified in such notice and until such time as the
Administrative Agent, upon notice to it by such Lender, shall notify the
Borrower and the other Lenders that the circumstances specified by it in such
notice no longer apply, (i) notwithstanding any other provision of this
Agreement, such Eurodollar Loans shall, automatically and without requirement of
further notice, or any payment pursuant to Section 4.03 or 4.04, be converted to
ABR Loans, (ii) the obligation of such Lender to make or continue Eurodollar
Loans shall be suspended, and, if the Borrower shall request in a Borrowing
Request or Conversion Request that the Lenders make Eurodollar Loans, the Loan
requested so to be made by such Lender shall instead be made as an ABR Loan.

                  Section 4.06 Expenses; Indemnity. (a) The Borrower shall: (i)
pay or reimburse the Administrative Agent and Collateral Agent for all
reasonable out-of-pocket costs and expenses incurred in connection with the
preparation and execution of, and any amendment, supplement or modification to,

                                       49

<PAGE>

this Agreement, any other Credit Documents, and any other documents prepared in
connection herewith or therewith, and the consummation of the transactions
contemplated hereby and thereby, including the reasonable fees and disbursements
of Sullivan & Cromwell, special counsel to the Lenders (or such other single
firm as is at the time acting in such capacity for the Lenders); (ii) pay or
reimburse each Lender, the Administrative Agent and the Collateral Agent for all
reasonable costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Agreement, any other Credit Documents, and
any such other documents, including the reasonable fees and disbursements of (A)
one firm of counsel in each jurisdiction and (B) if necessary, special counsel
in such areas as telecommunications regulations to the Lenders, the
Administrative Agent and the Collateral Agent; and (iii) pay and reimburse each
Lender for any payments made by such Lender to the Administrative Agent pursuant
to Section 10.06.

                  (b) Each Loan Party shall indemnify the Administrative Agent,
the Collateral Agent and each of the Lenders and their respective directors,
officers, employees, agents and Affiliates (for purposes of this paragraph,
each, an "Indemnitee") against, and to hold each Indemnitee harmless from, any
and all claims, liabilities, damages, losses, costs, charges and expenses
(including fees and expenses of counsel) incurred by or asserted against any
Indemnitee arising out of, in any way connected with, or as a result of (i) the
execution or delivery of any Credit Document or any agreement or instrument
contemplated by any Credit Document, the performance by the parties thereto of
their respective obligations under any Credit Document or the consummation of
the transactions and the other transactions contemplated by any Credit Document,
(ii) the use of the proceeds of the Loans or (iii) any claim, litigation,
investigation or proceeding relating to any of the foregoing, whether or not any
Indemnitee is a party thereto; provided that such indemnity shall not, as to any
Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or willful misconduct of such Indemnitee.

                  (c) Each Loan Party agrees to indemnify the Administrative
Agent, the Collateral Agent and the L/C Issuer and their respective directors,
officers, employees, agents and Affiliates (for purposes of this paragraph,
each, an "Indemnitee") against, and to hold each Indemnitee harmless from, any
and all claims, liabilities, damages, losses, costs, charges and expenses
(including fees and expenses of counsel) incurred by or asserted against any of
them arising out of, in any way connected with, or as a result of (i) the
issuance of any Letter of Credit or (ii) the failure of the L/C Issuer to honor
a drawing under any Letter of Credit as a result of any act or omission, whether
rightful or wrongful, of any Governmental Authority; provided that such
indemnity shall not, as to any such Indemnitee, be available to the extent that
such losses, claims, damages, liabilities or related expenses (i) are determined
by a court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or willful misconduct of such Indemnitee or
(ii) are attributable to taxes, levies, imposts, duties, deductions,
withholdings, fees, liabilities or similar charges whether or not the Borrower
is required to pay amounts with respect thereto under this Agreement. As between
the Borrower and the L/C Issuer, the Borrower assumes all risks of the acts and
omissions of, or misuse of a Letter of Credit by, a beneficiary of such Letter
of Credit. In furtherance and not in limitation of the foregoing, no Indemnitee
shall be responsible for any of the following: (A) the form, validity,
sufficiency, accuracy, genuineness or legal effects of any documents submitted
by any party in connection with the request and application for and issuance of
any Letter of Credit, even if it should in fact prove to be in any or all
respects invalid, insufficient, inaccurate, fraudulent or forged; (B) the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any Letter of Credit or rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason whatsoever; (C) any failure of a
beneficiary of any Letter of Credit to comply with any condition of drawing
thereunder; (D) any errors, omissions, interruptions or delays in transmission
or delivery of any messages, by mail, cable, telegraph, telex or otherwise,

                                       50

<PAGE>

whether or not in cipher; (E) any error in interpretation; (F) any loss or delay
in the transmission or otherwise of any document required in order to make a
drawing under any Letter of Credit or of the proceeds thereof; (G) any
misapplication by a beneficiary of any Letter of Credit of the proceeds of any
drawing thereunder; or (H) any consequences arising from or related to events or
circumstances beyond the control of the L/C Issuer, including any act or
omission, whether rightful or wrongful, of any Governmental Authority. In
furtherance and not in limitation of the specific provisions herein set
forth, any action taken or omitted by the L/C Issuer under or in connection with
any Letter of Credit or related certificates, if taken or omitted in good faith,
shall not result in or give rise to any liability of any Indemnitee to the
Borrower. Notwithstanding any of the foregoing, nothing in this Section 4.06(c)
shall relieve the Administrative Agent, the Collateral Agent or L/C Issuer of
any liability determined by a court of competent jurisdiction by final and
nonappealable judgment to have resulted from the gross negligence or willful
misconduct of the Administrative Agent, the Collateral or L/C Issuer.

                  (d) All amounts due under this Section 4.06 shall be payable
promptly within 10 Business Days after a written demand therefor in immediately
available funds.

                  Section 4.07 Replacement of Lenders. If no Default or Event of
Default shall have occurred and be continuing, and if any Lender has requested
the Borrower to pay amounts pursuant to Section 4.04 or has its obligations to
make Loans suspended pursuant to Section 4.05 (each an "Affected Lender"), then
the Borrower may, at its sole expense and effort, upon not less than 10 Business
Days' prior written notice to such Affected Lender and the Administrative Agent,
require such Affected Lender to assign and delegate, without recourse (in
accordance with and subject to the restrictions contained in Section 11.03), all
its interests, rights and obligations under this Agreement to an assignee that
shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment); provided that such Affected Lender shall have received
payment of any amounts owing to such Affected Lender hereunder (including,
without limitation, interest, fees, compensation and additional amounts under
this Article IV, in each case accrued to the effective date of such assignment
and any breakage costs payable in connection therewith), whereupon (i) each
assignee shall become a "Lender" for all purposes of this Agreement having a

                                   ARTICLE V.

                         Representations and Warranties

                  Section 5.01 Representations and Warranties. Each of the Loan
Parties as to itself, and as to any Consolidated Group Member that is a
Subsidiary thereof, represents and warrants to the Administrative Agent, L/C
Issuer and each Lender as follows:

                  (a) Corporate Organization and Power. Such Consolidated Group
         Member is duly organized and validly existing and in good standing
         under the laws of the jurisdiction of its organization; has all
         necessary corporate power to own its property and to carry on its
         business as now being conducted; and is duly licensed or qualified to
         do business and, if applicable, is in good standing in each
         jurisdiction in which the character of the properties owned or leased
         by it therein or in which the nature of the business transacted by it
         or the nature of the property owned or leased by it makes such
         licensing or qualification necessary, except where the failure to be so
         qualified, or to be in good standing, could not reasonably be expected,
         individually or in the aggregate, to have a Material Adverse Effect.
         All of the issued and outstanding shares of Capital Stock of such
         Consolidated Group Member have been duly authorized and validly issued
         and are fully paid and nonassessable. All such shares of a Consolidated
         Group Member owned by another Consolidated Group Member are owned
         beneficially, and of record, free of any Lien, except for Liens granted
         pursuant to the Credit Documents and Liens in respect of the Capital
         Stock of Vendor Facility Obligors.

                  (b) Subsidiaries. Schedule 5.01(b) identifies each direct or
         indirect Subsidiary of the Parent as of the date hereof and sets forth
         for each Subsidiary, (i) the jurisdiction of its organization, (ii) the
         percentage as the case may be (or other ownership interest) of issued
         and outstanding shares of each class of its Capital Stock owned by such
         Loan Party and if such percentage is not 100% (excluding directors'
         qualifying shares as required by law or a similar immaterial number of
         shares owned by third parties to comply with local shareholder
         residency requirements outside the United States), (iii) a description
         of each class of its authorized Capital Stock and the number of shares
         of each class issued and outstanding and (iv) its status as a
         Restricted Subsidiary, Temporary Restricted Subsidiary, Principal
         Subsidiary, Designated Foreign Subsidiary, Vendor Financing Obligor or
         Unrestricted Subsidiary, as the case may be.

                  (c) Corporate Authority. Such Consolidated Group Member has
         all necessary corporate power and authority to execute and deliver, and
         to Incur and perform its obligations under, each of the Credit
         Documents to which it is a party, all of which have been duly
         authorized by all proper and necessary corporate action. No consent or
         approval of stockholders is required as condition to the validity or
         performance of, or the exercise by the Administrative Agent, L/C Issuer
         or the Lenders of any of their rights or remedies under, any Credit
         Document.

                                       52

<PAGE>

                  (d) Binding Obligation. Each of the Credit Documents (other
         than the Notes) to which such Consolidated Group Member is a party
         constitutes and, when issued in accordance with the terms hereof, each
         Note will constitute, the valid and legally binding obligation of such
         Consolidated Group Member enforceable in accordance with its terms,
         subject as to enforcement to bankruptcy, insolvency, reorganization,
         moratorium and similar laws of general applicability relating to or
         affecting creditors' rights and to general equity principles.

                  (e)   Litigation; Labor Controversies.  Except as described in
         Schedule 5.01(e)-1 hereto, there are no proceedings or investigations
         now pending or, to the knowledge of any Responsible Officer,
         threatened against such Consolidated Group Member before any court or
         arbitrator or before or by any Governmental Authority which,
         individually or in the aggregate, if determined adversely to the
         interests of such Consolidated Group Member could reasonably be
         expected to have a Material Adverse Effect. Except as set forth on
         Schedule 5.01(e)-2, there are no labor controversies pending or, to
         the best knowledge of any Responsible Officer, threatened against such
         Consolidated Group Member that could reasonably be expected,
         individually or in the aggregate, to have a Material Adverse Effect.

                  (f) Governmental Approvals; No Conflicts. (i) All
         authorizations, consents, approvals, registrations, notices, exemptions
         and licenses with or from any Governmental Authority or other Person
         necessary for the execution, delivery and performance by such
         Consolidated Group Member of, and the Incurrence and performance of
         each of its obligations under, each of the Credit Documents to which
         such Consolidated Group Member is a party and the exercise by the
         Administrative Agent, L/C Issuer and the Lenders of their remedies
         under each of the Credit Documents have been effected or obtained and
         are in full force and effect except (A) filings necessary to perfect
         Liens created under the Security Documents, (B) consents from any
         Governmental Authority with respect to transfers of control of
         Telecommunications Licenses and (C) consents from any Governmental
         Authority or Person the absence of which, individually or in the
         aggregate, could not reasonably be expected to have a Material Adverse
         Effect.

                  (ii) There is no statute, regulation, rule, order or judgment,
         and no provision of any agreement or instrument binding upon such
         Consolidated Group Member, or affecting its Properties, and no
         provision of the certificate of incorporation or by-laws (or similar
         constitutive instruments) of such Consolidated Group Member, that would
         prohibit, conflict with or in any way impair the execution or delivery
         of, or the Incurrence or performance of any obligations of such
         Consolidated Group Member under, any Credit Document (other than dollar
         limitations on Incurrence of Indebtedness) or result in or require the
         creation or imposition of any Lien on Property of such Consolidated
         Group Member as a consequence of the execution, delivery and
         performance of any Credit Document other than as otherwise provided
         therein.

                  (g) Financial Condition. (i) The consolidated balance sheets
         of the Parent as of December 31, 1998 and 1999, together with
         consolidated statements of income, retained earnings, paid-in capital
         and surplus and cash flows for the fiscal year then ended, reported

                                       53

<PAGE>

         upon by Grant Thornton LLP, heretofore delivered to the Administrative
         Agent and the Lenders, fairly present the Parent's consolidated
         financial condition and consolidated results of operations and
         transactions in capital accounts as of the dates and for the periods
         referred to and have been prepared in accordance with GAAP consistently
         applied throughout the period involved. There are no material
         liabilities (whether known or unknown, direct or indirect, fixed or
         contingent, and of any nature whatsoever) of the Consolidated Group on
         a consolidated basis as of the date of such balance sheet that are not
         reflected therein or in the notes thereto.

                  (ii) Except as provided in Schedule 5.01(g)(ii), there has
         been no event or circumstance that has had a Material Adverse Effect
         since December 31, 1999.

                  (h) Taxes. Such Consolidated Group Member has filed or caused
         to be filed all material tax returns that are required to be filed and
         paid and discharged material taxes that are shown to be due and payable
         on said returns or on any assessment made against it or any of its
         property and all other taxes, assessments or other governmental
         charges, imposed on it or any of its property by any Governmental
         Authority, except to the extent that (i) (A) such taxes, assessments
         and governmental charges which are being contested in good faith and by
         appropriate proceedings and (B) adequate reserves are being maintained
         (in accordance with GAAP) or (ii) any failure to file such tax returns
         or to pay and discharge such taxes, assessments or governmental charges
         could not reasonably be expected to result in a Material Adverse
         Effect. No notices of tax liens have been filed and no claims are being
         asserted concerning any such taxes, which liens or claims could
         reasonably be expected, individually or in the aggregate, to have a
         Material Adverse Effect. The charges, accruals and reserves on the
         books of the Parent and its Subsidiaries on a consolidated basis for
         any taxes or other governmental charges are adequate.

                  (i) Margin Regulations; Margin Stock; Use of Proceeds. Such
         Consolidated Group Member is not engaged principally, or as one of its
         primary activities, in the business of extending credit for the purpose
         of purchasing or carrying margin stock. The proceeds of the Loans and
         Letters of Credit are to be used solely for the purposes set forth in
         and permitted by Section 8.02(f). The Borrower will not use the
         proceeds of any Loan or Letter of Credit in a manner that violates any
         provision of the Margin Regulations.

                  (j) Compliance with ERISA. Each member of the ERISA Group is
         in compliance with the applicable provisions of ERISA and the Code with
         respect to each Plan, except for any failure so to comply that,
         individually or in the aggregate, could not reasonably be expected to
         have a Material Adverse Effect. No member of the ERISA Group has (i) an
         accumulated funding deficiency under Section 412 of the Code in respect
         of any Pension Plan, whether or not waived, (ii) failed to make any
         contribution or payment to any Pension Plan, or made any amendment to
         any Pension Plan, which has resulted or could result in the imposition
         of a Lien or the posting of a bond or other security under Section
         302(f) of ERISA or Section 401(a)(29) of the Code, (iii) incurred any
         liability under Title IV of ERISA other than a liability to the PBGC
         for premiums under Section 4007 of ERISA, all of which have been paid
         or (iv) engaged in a transaction with respect to a Plan, which
         (assuming the taxable period of such transaction, within the meaning of

                                       54

<PAGE>

         Section 4975(f)(2) of the Code, to have expired as of the date hereof)
         has resulted or could reasonably be expected to result in such member
         being subject to a material tax or penalty imposed by Section 4975 of
         the Code or Section 502 of ERISA. As of the last day of the most recent
         plan year ended prior to the date hereof, the actuarially determined
         present value of all benefit liabilities (as determined on the basis of
         the actuarial assumptions contained in the most recent actuarial
         valuation) did not exceed the then fair market value of the assets of
         any Pension Plan by more than $25.0 million, and there has been no
         material change in the financial condition of any Pension Plan since
         the last day of the most recent plan year. No member of the ERISA
         Group has incurred any withdrawal liability under Part I of Subtitle E
         of Title IV of ERISA with respect to a Multiemployer Plan in an amount
         in excess of $25.0 million, nor has any member of the ERISA Group
         received any notification that any Multiemployer Plan is in
         reorganization or has been terminated within the meaning of Title IV
         of ERISA, and no Multiemployer Plan is reasonably expected to be in
         reorganization or to be terminated where such reorganization or
         termination has had or could reasonably be expected to have, through
         increases in the contributions required to be made or otherwise, a
         Material Adverse Effect.

                  (k) Investment Company and Holding Company Status. Such
         Consolidated Group Member is not (i) an "investment company" or a
         company "controlled" by an "investment company" within the meaning of
         the Investment Company Act of 1940, as amended, or (ii) subject to
         regulation under the Public Utility Holding Company Act of 1935, the
         Federal Power Act, each as amended, or any foreign, federal, state or
         local statute or regulation limiting its ability to Incur indebtedness
         for money borrowed as contemplated hereby.

                  (l) Properties and Licenses. (i) On the date hereof, excluding
         the licenses described in Section 5.01(m) (and other spectrum or
         broadcasting licenses that are not Telecommunications Licenses), such
         Consolidated Group Member has good and marketable title to, or valid
         leasehold interests in, all of its properties and assets that are
         reflected on the consolidated balance sheet of the Parent as of
         December 31, 1999, referred to in Section 5.01(g)(i) except for such
         immaterial properties and assets as have been disposed of in the
         ordinary course of business and except for minor defects in title that
         do not interfere with the ability of such Consolidated Group Member to
         conduct its business as now conducted. All such assets and properties
         are so owned or held free and clear of all Liens, except Permitted
         Liens.

                  (ii) Such Consolidated Group Member owns, or is licensed to
         use, all trademarks, trade names, copyrights, patents and other
         intellectual property material to its business, and the use thereof by
         such Consolidated Group Member does not infringe upon the rights of any
         other Person, except for any such infringements that, individually or
         in the aggregate, could not reasonably be expected to result in a
         Material Adverse Effect.

                  (iii) Such Consolidated Group Member has all licenses and
         permits that are material to the business of such Consolidated Group
         Member. Each license or permit that is material to the business of such

                                       55

<PAGE>

         Consolidated Group Member is valid and in full force and effect, and
         such Consolidated Group Member is in compliance in all material
         respects with the terms and conditions thereof.

                  (m)   Telecommunications Business and Telecommunications
         Licenses. (i) The Parent and its Subsidiaries are in compliance in all
         material respects with the Communications Act and with all applicable
         rules, regulations and policies of the FCC.

                  (ii) Such Consolidated Group Member has disclosed on Schedule
         5.01(m)(ii) a complete and accurate list of (A) all 38 and 28 GHZ
         spectrum licenses and (B) all other licenses, the loss of which could
         reasonably be expected to result in a Material Adverse Effect on a
         consolidated basis, issued by the FCC and held as of the date hereof by
         such Consolidated Group Member (the "Telecommunications Licenses"). All
         of the Telecommunications Licenses are currently valid and in full
         force and effect. No Responsible Officer has knowledge or could have
         reasonably been expected to have knowledge of any investigation, notice
         of apparent liability, violation, forfeiture or other order or
         complaint issued by or before any court or regulatory body, including
         the FCC, or of any other proceedings (other than FCC rulemaking
         proceedings and other proceedings relating to the wireless
         communications industry generally) which could in any manner materially
         threaten or adversely affect the validity or continued effectiveness of
         any of the Telecommunications Licenses, except as disclosed on Schedule
         5.01(m)(ii).

                  (iii) Except as disclosed on Schedule 5.01(m)(iii), no event
         has occurred which (A) results in, or after notice or lapse of time or
         both would result in, revocation, suspension, modification,
         non-renewal, impairment, restriction or termination of, or order of
         forfeiture with respect to, any Telecommunications License the loss of
         which could reasonably be expected to have a Material Adverse Effect or
         (B) materially and adversely affects or could reasonably be expected in
         the future to materially adversely affect any of the rights of such
         Consolidated Group Member thereunder.

                  (iv) Such Consolidated Group Member has duly filed in a timely
         manner all material filings, reports, applications, documents,
         instruments and information required to be filed by them under the
         Communications Act, and all such filings are true and complete in all
         material respects.

                  (v) Such Consolidated Group Member has no reason to believe
         that any of the Telecommunications Licenses will not be renewed in the
         ordinary course.

                  (n) Investments. Such Consolidated Group Member has disclosed
         on Schedule 5.01(n) a complete and accurate list of all Investments
         existing on the date hereof.

                  (o) Compliance with Laws and Charter Documents. (i) Such
         Consolidated Group Member is not, or as a result of performing any of
         its obligations under the Credit Documents will not be, in violation in
         any material respect of (a) any law, statute, rule, regulation or order
         of any Governmental Authority (including Environmental Laws) applicable
         to it or its material properties or assets or (b) its certificate of
         incorporation, by-laws or any similar constitutive document.

                                       56

<PAGE>

                  (ii) Such Consolidated Group Member has all necessary
         authorizations, consents, approvals, registrations, franchises,
         licenses and permits, with or from Governmental Authorities and other
         Persons for it to own its properties and conduct its business as
         currently conducted and contemplated, except to the extent failure to
         have the same could not, individually or in the aggregate, reasonably
         be expected to have a Material Adverse Effect.

                  (p) Environmental Protection. To any Responsible Officer's
         knowledge or based on any knowledge such Responsible Officer could
         reasonably be expected to have, all real property owned or leased by
         such Consolidated Group Member is free of contamination from any
         Hazardous Substance, or a constituent thereof, that could result in the
         incurrence of liabilities that would reasonably be expected to have a
         Material Adverse Effect. To any Responsible Officer's knowledge or
         based on any knowledge such Responsible Officer could reasonably be
         expected to have, no such Consolidated Group Member has caused or
         suffered to occur any release of any Hazardous Substance into the
         environment or any other conditions that, individually or in the
         aggregate, could reasonably be expected to result in the incurrence of
         material liabilities or any material violations of any Environmental
         Laws that would reasonably be expected to have a Material Adverse
         Effect. To any Responsible Officer's knowledge or based on any
         knowledge such Responsible Officer could reasonably be expected to
         have, no such Consolidated Group Member has caused or suffered to occur
         any condition on any of its property that could give rise to the
         imposition of any lien under the Environmental Laws that would
         reasonably be expected to have a Material Adverse Effect. To any
         Responsible Officer's knowledge or based on any knowledge such
         Responsible Officer could reasonably be expected to have, no
         Consolidated Group Member is engaged in any manufacturing or any other
         operations, other than the use and storage in the ordinary course of
         their business of petroleum products and amounts of Hazardous
         Substances customarily used in the maintenance of office buildings and
         used for provision of Telecommunications Business that require the use,
         handling, transportation, storage or disposal of any Hazardous
         Substance, where such operations require permits or are otherwise
         regulated pursuant to the Environmental Laws.

                  (q) Insurance. All of the properties and operations of such
         Consolidated Group Member of a character usually insured by companies
         of established reputation engaged in the same or a similar business
         similarly situated are adequately insured, by financially sound and
         reputable insurers, against loss or damage of the kinds and in amounts
         customarily insured against by such Persons, and such Consolidated
         Group Member carries, with such insurers in customary amounts as is
         usually carried by companies of established reputation engaged in the
         same or a similar business similarly situated, except for self
         insurance (including deductibles) maintained in accordance with
         customary norms.

                  (r) Compliance with Agreements. Such Consolidated Group Member
         is not in default in the performance, observance or fulfillment of any
         of the obligations, covenants or conditions contained in any
         Contractual Obligation to which it is a party, which default could
         reasonably be expected, individually or in the aggregate, to have a
         Material Adverse Effect.

                  (s) Security Documents. The provisions of each of (i) the
         Blocked Account Agreements, (ii) the Securities Account Control
         Agreements, (iii) the Pledge and Security Agreement, (iv) the Patent
         Assignment Agreement (if entered into), (v) the Trademark Assignment
         Agreements and (vi) the Copyright Assignment Agreements (if entered
         into), duly executed by the Loan Parties, the Administrative Agent on
         behalf of itself and the Lenders and the Collateral Agent will be
         effective to create in favor of the Collateral Agent a valid, binding
         and enforceable security interest in the collateral described therein
         (the "Collateral"), which, upon the filing of financing statements and
         the taking of the other actions specified in the Security Documents,
         will constitute a fully perfected first and prior security interest
         superior in right to any Liens permitted under the Credit Documents,
         except (i) as otherwise contemplated by such Security Documents

of, the Borrower and all other amounts from time to time owing to the Lenders,
L/C Issuer or the Administrative Agent by the Borrower under this Agreement and
under the Notes and by any Loan Party under any of the other Credit Documents,
and all obligations of any Loan Party to any Lender or L/C Issuer in respect of
any Hedging Obligations, in each case strictly in accordance with the terms
thereof (such obligations being herein collectively called the "Guaranteed
Obligations"). Each Guarantor hereby further jointly and severally agrees that
if any Borrower shall fail to pay in full when due (whether at stated maturity,
by acceleration or otherwise) any of the Guaranteed Obligations, the Guarantor
will promptly pay the same, without demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the Guaranteed
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, by acceleration or otherwise) in accordance with the terms of
such extension or renewal.

                  Section 6.02 Obligations Unconditional. (a) Each Guarantor
agrees that its obligations under Section 6.01 hereof are absolute and
unconditional, joint and several, irrespective of the value, genuineness,
validity, regularity or enforceability of the obligations of the Borrower under
this Agreement, the Notes or any other agreement or instrument referred to
herein or therein, or any substitution, release of exchange of any other
guarantee of or security for any of the Guaranteed Obligations, and, to the
fullest extent permitted by applicable law, irrespective of any other
circumstance whatsoever that might otherwise constitute a legal or equitable
discharge or defense of a surety or guarantor, it being the intent of this
Section 6.02 that the obligations of such Guarantor hereunder shall be absolute
and unconditional, joint and several, under any and all circumstances.

                  (b) Without limiting the generality of the foregoing, each
Guarantor agrees that the occurrence of any one or more of the following shall
not alter or impair the liability of such Guarantor hereunder which shall remain
absolute and unconditional as described above:

                  (i) at any time or from time to time, without notice to the
         Guarantor, the time for any performance of or compliance with any of
         the Guaranteed Obligations shall be extended, or such performance or
         compliance shall be waived;

                  (ii) any of the acts mentioned in any of the provisions of
         this Agreement or the Notes or any other agreement or instrument
         referred to herein or therein shall be done or omitted;

                  (iii) the maturity of any of the Guaranteed Obligations shall
         be accelerated, or any of the Guaranteed Obligations shall be modified,
         supplemented or amended in any respect, or any right under this
         Agreement or the Notes or any other agreement or instrument referred to
         herein or therein shall be waived or any other Guarantee of any of the
         Guaranteed Obligations or any security therefor shall be released or
         exchanged in whole or in part or otherwise dealt with; or

                  (iv) any lien or security interest granted to, or in favor of,
         the Administrative Agent of any Lender or Lenders as security for any
         of the Guaranteed Obligations shall fail to be perfected.

                                       59
<PAGE>

Each Guarantor hereby expressly waives diligence, presentment, demand of
payment, protest and all notices whatsoever, and any requirement that the
Administrative Agent or any Lender exhaust any right, power or remedy or proceed
against the Borrower under this Agreement or the Notes or any other agreement or
instrument referred to herein or therein, or against any other Person under any
other Guarantee of, or security for, any of the Guaranteed Obligations.

                  Section 6.03 Reinstatement. Each Guarantor agrees that its
obligations under this Article VI shall be automatically reinstated if and to
the extent that for any reason any payment by or on behalf of the Borrower in
respect of the relevant Guaranteed Obligations is rescinded or must be otherwise
restored by any holder of any of such Guaranteed Obligations, whether as a
result of any proceedings in bankruptcy or reorganization or otherwise and each
Guarantor jointly and severally agrees that it will indemnify the Administrative
Agent and each Lender on demand for all reasonable costs and expenses
(including, without limitation, fees of counsel) incurred by the Administrative
Agent or such Lender in connection with such rescission or restoration,
including any such costs and expenses incurred in defending against any claim
alleging that such payment constituted a preference, fraudulent transfer or
similar payment under any bankruptcy.

                  Section 6.04 Subrogation. Each Guarantor hereby jointly and
severally agrees that until the payment and satisfaction in full of all
Guaranteed Obligations and the expiration and termination of the Commitments of
the Lenders under this Agreement it shall not exercise any right or remedy
arising by reason of any performance by it of its Guarantee in Section 6.01
hereof, whether by subrogation or otherwise, against the Borrower or any
Guarantor of any of the Guaranteed Obligations or any security for any of the
Guaranteed Obligations.

                  Section 6.05 Remedies. Each Guarantor jointly and severally
agrees that, as between such Guarantor and the Lenders, the obligations of the
Borrower under this Agreement and the Notes may be declared to be forthwith due
and payable as provided in Section 9.01 hereof (and shall be deemed to have
become automatically due and payable in the circumstances provided in said
Section 9.01) for purposes of Section 6.01 hereof notwithstanding any stay,
injunction or other prohibition preventing such declaration (or such obligations
from becoming automatically due and payable) as against such Borrower and that,
in the event of such declaration (or such obligations being deemed to have
become automatically due and payable), such obligations (whether or not due and
payable by such Borrower) shall forthwith become due and payable by such
Guarantor for purposes of said Section 6.01.

                  Section 6.06 Continuing Guarantee. Each Guarantor agrees that
its Guarantee in this Article VI is a continuing Guarantee, and shall apply to
all Guaranteed Obligations whenever arising.

                  Section 6.07 Rights of Contribution. (a) The Loan Parties
hereby agree, as between themselves, that if any Loan Party shall become an
Excess Funding Guarantor by reason of the payment by such Loan Party of any
Guaranteed Obligations, each other Loan Party shall, on demand of such Excess
Funding Guarantor (but subject to the next sentence), pay to such Excess Funding
Guarantor an amount equal to such Relevant Obligor's Pro Rata Guarantee Share
(as defined below and determined, for this purpose, without reference to the

                                                   60

Properties, debts and liabilities of such Excess Funding Guarantor) of the
Excess Payment (as defined in paragraph (b) below) in respect of such Guaranteed
Obligations. The payment obligation of a Loan Party to any Excess Funding
Guarantor under this Section 6.07 shall be subordinate and subject in right of
payment to the prior payment in full of the obligations of such Loan Party under
the other provisions of this Article VI and such Excess Funding Guarantor shall
not exercise any right or remedy with respect to such excess until payment and
satisfaction in full of all such obligations.

                  (b) For purposes of this Section 6.07; (i) "Excess Funding
Guarantor" shall mean, in respect of any Guaranteed Obligations, a Loan Party
that has paid an amount in excess of its Pro Rata Guarantee Share of such
Guaranteed Obligations; (ii) "Excess Payment" shall mean, in respect of any
Guaranteed Obligations, the amount paid by an Excess Funding Guarantor in excess
of its Pro Rata Guarantee Share of such Guaranteed Obligations; (iii) "Pro Rata
Guarantee Share" shall mean, for any Loan Party, the ratio (expressed as a
percentage) of the amount of such Loan Party's Net Assets to the amount of the
aggregate Net Assets of all of the Loan Parties, in each case determined as of
(A)(x) with respect to any Loan Party that was a party to this Agreement on the
Effective Date, such Effective Date or (y) with respect to any other Loan Party,
the date such Loan Party becomes a Loan Party hereunder or (B) the date any
demand is made hereunder in respect of the Guaranteed Obligations, whichever
date results in the higher amount (the "Determination Date"); and (iv) the "Net
Assets" of any Loan Party shall mean the amount by which the aggregate present
fair saleable value of all assets of such Loan Party (excluding any shares of
stock of any other Loan Party) exceeds the amount of all the debts and
liabilities of such Loan Party (including contingent, subordinated, unmatured
and unliquidated liabilities, but excluding the obligations of such Loan Party
under this Article VI, assuming the full utilization of permitted borrowings
under this Agreement and after giving effect, on a pro forma basis (but without
duplication), to all such obligations of such Loan Party to be Incurred or
assumed as of the Effective Date).

                  Section 6.08 Limitation on Guarantee Obligations.
Notwithstanding any other provision of this Agreement to the contrary, in any
action or proceeding involving any state corporate law or any state or federal
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, the Loan Parties agree that if the obligations of any Loan
Party hereunder would otherwise be held or determined to be void, invalid or
unenforceable on account of the amount of its liability under this Article VI,
then notwithstanding any other provision of this Agreement to the contrary, the
amount of such liability shall, without any further action by such Loan Party or
any other person, be automatically limited and reduced to the highest amount
that is valid and enforceable and not subordinated to the claims of other
creditors as determined in such action or proceeding.

                  Section 6.09 Additional Guarantors. Upon the execution and
delivery by any Person of a guarantee supplement in substantially the form of
Exhibit 6.09 hereto (each a "Guarantee Supplement"), such Person shall be
referred to as an "Additional Guarantor," shall be and become a Guarantor, and
each reference in this Agreement and other Credit Documents to Guarantor shall
be a reference to such Additional Guarantor.

         expected to have a Material Adverse Effect, shall be rendered against
         such Loan Party and there shall be any period of 30 consecutive days
         during which a stay of such judgment or attachment, by reason of a

         of $15.0 million; any member of the ERISA Group fails to make a payment

                 (k) any Change of Control shall occur, then, and at any time
         during the continuance of such Event of Default, the Required Lenders,
         may, by written notice to the Borrower, take either or both of the
         following actions, at the same or different times: (i) terminate
         forthwith the Commitments and (ii) declare any Loans then outstanding
         to be due, whereupon the principal of the Loans so declared to be due,
         together with accrued interest thereon and any unpaid amounts accrued
         under the Credit Documents, shall become forthwith due, without
         presentment, demand, protest or any other notice of any kind (all of
         which are hereby expressly waived by the Loan Parties); provided that,
         in the case of any Event of Default described in Section 9.01(g) or
         (h) occurring with respect to the Borrower, the Commitments shall
         automatically and immediately terminate and the principal of all Loans
         then outstanding, together with accrued interest thereon and any
         unpaid amounts accrued under the Credit Documents, shall automatically
         and immediately become due without presentment, demand, protest or any
         other notice of any kind (all of which are hereby expressly waived by
         the Loan Parties).

Unrestricted Subsidiary pursuant to Article XII without the occurrence of a
Default hereunder after giving effect to such action. Any such Loan Party shall
be deemed converted to an Unrestricted Subsidiary provided that such conversion
shall be deemed to be an Investment in Unrestricted Subsidiaries under Section

                    The Administrative and Collateral Agents

                  Section 10.01 The Agency. Each Lender appoints The Bank of New
York as its Administrative Agent and Collateral Agent hereunder and under the
Credit Documents and irrevocably authorizes the Administrative Agent and
Collateral Agent to take such action on its behalf and to exercise such powers
hereunder and thereunder as are specifically delegated to the Administrative
Agent and Collateral Agent by the terms hereof and thereof, together with such
powers as are reasonably incidental thereto, including the exercise of powers
delegated to the Administrative Agent and Collateral Agent and the Lenders
thereby, and the Administrative Agent and Collateral Agent hereby accept such
appointment subject to the terms hereof. The relationship between the
Administrative Agent and Collateral Agent and the Lenders shall be that of agent
and principal only and nothing herein shall be construed to constitute the
Administrative Agent and Collateral Agent a trustee or fiduciary for any Lender
nor to impose on the Administrative Agent and Collateral Agent duties or
obligations other than those expressly provided for herein.

                  Section 10.02 The Administrative Agent's Duties. The
Administrative Agent and Collateral Agent shall promptly forward to each Lender
copies, or notify each Lender as to the contents, of all notices received from
the Borrower pursuant to the terms of this Agreement or the Credit Documents
and, in the event that the Borrower fails to pay when due the principal of or
interest on any Loan, the Administrative Agent shall promptly give notice
thereof to the Lenders. As to any other matter not expressly provided for herein
or under the other Credit Documents, the Administrative Agent and Collateral
Agent shall have no duty to act or refrain from acting with respect to the
Borrower, except upon the instructions of the Required Lenders. The
Administrative Agent and Collateral Agent shall not be bound by any waiver,
amendment, supplement, or modification of this Agreement or the other Credit
Documents which affects its duties hereunder and thereunder, unless it shall
have given its prior written consent thereto. The Administrative Agent and
Collateral Agent shall have no duty to ascertain or inquire as to the
performance or observance of any of the terms, conditions, covenants or
agreements binding on the Borrower pursuant to any Credit Document nor shall the
Administrative Agent or Collateral Agent be deemed to have knowledge of the
occurrence of any Default or Event of Default (other than a failure of the
Borrower to pay when due the principal or interest on any Loan), unless it shall
have received written notice from the Borrower or a Lender specifying such
Default or Event of Default and stating that such notice is a "Notice of
Default".

                  Section 10.03 Limitation of Liabilities. Each of the Lenders
and the Loan Parties agree that (i) neither the Administrative Agent nor
Collateral Agent any of its or their officers or employees shall be liable for
any action taken or omitted to be taken by any of them hereunder except for its
or their own gross negligence or wilful misconduct, (ii) neither the
Administrative Agent nor Collateral Agent nor any of its or their officers or
employees shall be liable for any action taken or omitted to be taken by any of
them in good faith in reliance upon the advice of counsel, independent public
accountants or other experts selected by the Administrative Agent, and (iii) the
Administrative Agent and Collateral Agent shall be entitled to rely upon any
notice, consent, certificate, statement or other document believed by it to be
genuine and correct and to have been signed and/or sent by the proper Persons.

<PAGE>

                  Section 10.04 The Administrative Agent and Collateral Agent as
a Lender. The Administrative Agent and Collateral Agent may, without any
liability to account, maintain deposits or credit balances for, invest in, lend
money to and generally engage in any kind of banking or investment banking
business with any Loan Party or Subsidiary or Affiliate of the Borrower as if it
were any other lender and without any duty to account therefor to the other
Lenders.

                  Section 10.05 Lender Credit Decision. Neither the
Administrative Agent, Collateral Agent nor any of its or their Affiliates,
officers or employees has any responsibility for, gives any guarantee in respect
of, nor makes any representation to the Lenders as to, (i) the condition,
financial or otherwise, of the Parent, the Borrower or any Subsidiary thereof or
the truth of any representation or warranty given or made in this Agreement, or
in connection here with or therewith or (ii) the validity, execution,
sufficiency, effectiveness, construction, adequacy, enforceability or value of
this Agreement or any other document or instrument related hereto or thereto.
Except as specifically provided herein, neither the Administrative Agent nor
Collateral Agent nor any of its or their Affiliates, officers or employees shall
have any duty or responsibility, either initially or on a continuing basis, to
provide any Lender with any credit or other information with respect to the
operations, business, property, condition or creditworthiness of the Borrower or
any of its Subsidiaries, whether such information comes into the Administrative
Agent's or Collateral Agent's possession on or before the Effective Date or at
any time thereafter. Each Lender acknowledges that (i) it has, independently and
without reliance upon the Administrative Agent or Collateral Agent or any other
Lender, based on such documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement and (ii)
all information reviewed by it in its credit analysis or otherwise in connection
herewith (including information relating to the Administrative Agent and
Collateral Agent) has been provided solely by or on behalf of the Parent and the
Borrower, and neither the Administrative Agent nor the Collateral Agent has no
responsibility for such information. Each Lender also acknowledges that it will
independently and without reliance upon the Administrative Agent or Collateral
Agent or any other Lender, 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 any Credit Document.

                  Section 10.06 Indemnification. (a) Each Lender agrees to
indemnify the Administrative Agent and Collateral Agent, to the extent not
reimbursed by any of the Loan Parties, ratably in proportion to such Lender's
Commitment (as of the time of the incurrence of the liability being indemnified
against), from and against any and all liabilities, obligations, losses, claims,
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 the Administrative Agent and Collateral Agent in any way
relating to or arising out of any Credit Document, or any action taken or
omitted to be taken by the Administrative Agent and Collateral Agent hereunder
or thereunder; provided 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 the gross negligence or wilful
misconduct of the Administrative Agent and Collateral Agent or any of its
officers or employees. Without limiting the foregoing, each Lender agrees to
reimburse the Administrative Agent and Collateral Agent promptly upon demand for
its ratable share of any out-of-pocket expenses (including fees and
disbursements of counsel incurred by the Administrative Agent and Collateral

                                       95

<PAGE>

Agent in such capacity in connection with the preparation, execution or
enforcement of, or legal advice in respect of rights or responsibilities under,
any Credit Document or any amendments or supplements hereto or thereto, to the
extent that the Administrative Agent and Collateral Agent is not reimbursed for
such expenses by any of the Loan Parties).

                  (b) Except for action expressly required of the Administrative
Agent hereunder, the Administrative Agent shall in all cases be fully justified
in failing or refusing to act hereunder unless it shall receive further
assurances to its satisfaction from the Lenders of their indemnification
obligations under this Section 10.06 against any and all liability and expense
that may be incurred by it by reason of taking or continuing to take any such
action.

                  (c) The provisions of this Section 10.06 shall remain
operative and in full force and effect regardless of the expiration of the term
of this Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the reduction or termination of any Commitments,
the invalidity or unenforceability of any term or provision of any Credit
Document, or any investigation made by or on behalf of the Lenders.

                  Section 10.07 Successor Administrative Agent and Collateral
Agent. The Administrative Agent or Collateral Agent may resign at any time, in
such capacity, by giving written notice thereof to the Lenders and the Loan
Parties. Upon any such resignation, the Required Lenders shall have the right to
appoint a successor Administrative Agent or Collateral Agent and, so long as the
Borrower is not in Default, with the consent of the Borrower provided such
consent shall not be unreasonably withheld. If no successor Administrative Agent
or Collateral Agent shall have been so appointed by the Required Lenders and
shall have accepted such appointment within 30 days after the resigning
Administrative Agent's giving of notice of resignation the resigning
Administrative Agent or Collateral Agent may, on behalf of the Lenders, appoint
a successor Administrative Agent or Collateral Agent , which shall be a
commercial bank organized or licensed under the laws of the United States of
America or of any State thereof and having a combined capital and surplus of at
least $250.0 million. Upon the acceptance of any appointment as Administrative
Agent or Collateral Agent hereunder by a successor Administrative Agent or
Collateral Agent, such successor Administrative Agent or Collateral Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the resigned Administrative Agent or Collateral Agent, and the
resigned Administrative Agent or Collateral Agent shall be discharged from its
duties and obligations in such capacity under this Agreement and the other
Credit Documents. After any Administrative Agent's or Collateral Agent's
resignation or removal as Administrative Agent or Collateral Agent, the
provisions of this Article X shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Administrative Agent or Collateral
Agent under this Agreement or the other Credit Documents.

                                   ARTICLE XI.

                          Evidence of Loans; Transfers

                  Section 11.01 Evidence of Loans. (a) Each Lender shall
maintain, in accordance with its customary and usual practice, accounts
evidencing the Indebtedness of the Borrower to such Lender resulting from each

                                       96

<PAGE>

Loan made by such Lender from time to time, including the amounts of principal
and interest payable and paid to such Lender in respect of Loans.

                  (b) The Administrative Agent shall maintain, on behalf of and
as agent for the Borrower, in accordance with its customary and usual practice,
(i) a copy of each Assignment and Acceptance delivered to it and (ii) written or
electronic records for the recordation of (A) the amount of each Lender's
Commitments, (B) the amount of each Loan, whether such Loan is a Revolving
Credit Loan, or Term Loan and the interest rate and the Interest Period
applicable thereto, (C) the amount of any principal, fees or interest paid, due
and payable or to become due and payable from the Borrower to each Lender
hereunder, (D) the amount of any payments received by the Administrative Agent
hereunder from the Borrower and each Lender's share thereof and (E) the name and
address of the Assignee, the amount of the Assignee's Commitment and the
principal amount of each Loan owing to each Lender or such Assignee. The
Administrative Agent's written records described above shall be available for
inspection during ordinary business hours by the Borrower or any Lender or
Assignee from time to time upon reasonable prior notice to the Administrative
Agent.

                  (c) The entries made in the Administrative Agent's written or
electronic records and the foregoing accounts shall be prima facie evidence of
the existence and amounts of the Indebtedness of the Borrower therein recorded;
provided, however, that the failure of any Lender or the Administrative Agent to
maintain any such account or such records, as applicable, or any error therein,
shall not in any manner affect the validity or enforceability of any obligation
of the Borrower to repay any Loan actually made by such Lender in accordance
with the terms of this Agreement. The entries in such records relating to
assignments shall be conclusive, in the absence of manifest error, and the
Borrower, the Administrative Agent and the Lenders may treat each Person whose
name is recorded in such records as the owner of the Loans recorded therein for
all purposes of this Agreement.

                  (d) The Borrower's obligations to repay any Loan assigned to a
Federal Reserve Bank by a Lender shall, to the extent requested by such Lender
in order to effect such assignment, be evidenced by one or more Notes, in
substantially the form of Exhibit 11.01(d)-1 or Exhibit 11.01(d)-2, as
appropriate. Such Note shall be in the principal amount of the Loan or Loans so
assigned and stated to mature on the applicable Commitment Termination Date and
bear interest from its date until paid in full on the principal amount of the
Loan outstanding thereunder payable at the rates and in the manner provided
herein.

                  Section 11.02    Participations.  Any Lender may at any time
grant to one or more financial institutions (each a "Participant") participating
interests in its Commitment or any or all of its Loans. In the event of any such
grant by a Lender of a participating interest to a Participant, whether or not
upon notice to any of the Loan Parties or the Administrative Agent, such Lender
shall maintain on behalf of the Borrower a register of the information set forth
in Section 11.01(b)(ii)(A) through (E) with respect to such Participants and
shall remain responsible for the performance of its obligations hereunder, and,
except to the extent such participating interest has been granted pursuant to
Section 4.02(e), the Loan Parties and the Administrative Agent shall continue to
deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement. Any agreement pursuant to which any
Lender may grant such a participating interest shall provide that such Lender
shall retain the sole

                                       97

<PAGE>

right and responsibility to enforce the obligations of each of the Loan Parties
hereunder including the right to approve any amendment, modification or waiver
of any provision of this Agreement; provided that such participation agreement
may provide that such Lender will not agree to any modification, amendment or
waiver of this Agreement described in clauses (i) through (vi), inclusive, of
Section 13.06 without the consent of the Participant. An assignment or other
transfer which is not permitted by Section 11.03 shall be given effect for
purposes of this Agree ment only to the extent of a participating interest
granted in accordance with this Section 11.02.

                  Section 11.03 Assignments. (a) Any Lender may at any time
assign to one or more financial institutions (each an "Assignee") all, or a
proportionate part of all, of its rights and obligations under this Agreement,
and such Assignee shall assume such rights and obligations, pursuant to an
instrument, in substantially the form of Exhibit 11.03(a) (an "Assignment and
Acceptance"), executed by such Assignee and such transferor Lender, with (and
subject to) the signed consent (which consent shall not be unreasonably
withheld) of the Parent, the Borrower, the Administrative Agent and the L/C
Issuer; provided that (i) the foregoing consent requirement shall not be
applicable in the case of an assignment or other transfer by any Lender to an
Affiliate of such Lender, to another Lender, a Federal Reserve Bank or, in the
case of a Lender that is a fund that invests in bank loans, to a fund under
common management, or advised by the same investment adviser (or Affiliate
thereof) (an "Approved Fund") and (ii) the aforementioned consent of the Parent
and the Borrower shall not be required if there shall have occurred an Event of
Default that is continuing. Upon execution and delivery of an Assignment and
Acceptance and payment by such Assignee to such transferring Lender of an amount
equal to the purchase price agreed between such transferring Lender and such
Assignee and payment by the transferring Lender or the Assignee of an assignment
fee of $3,500 to the Administrative Agent (provided that only one such fee shall
be payable in the event of simultaneous transfers to two or more funds that
invest in bank loans and are Approved Funds as to each other), such Assignee
shall be a Lender party to this Agreement and shall have all the rights and
obligations of a Lender with a Commitment or an outstanding Loan as set forth in
such Assignment and Acceptance, and the transferring Lender shall be released
from its obligations hereunder to a corresponding extent, and no further consent
or action by any party shall be required. Revolving Credit Loans, Term Loan A
Loans and Term Loan B Loans may be assigned separately and not pro rata. Any
assignment pursuant to this Section 11.03 shall become effective upon the
recording thereof in the written records maintained by the Administrative Agent
pursuant to Section 11.01(b).

                  (b) An Assignment and Acceptance must be in a minimum amount
of $5.0 million unless otherwise agreed to by the Borrower, except (i) as to an
Assignment and Acceptance between Lenders or between a Lender and any Affiliate
of such Lender or Approved Fund of such Lender to which no minimum dollar amount
shall apply or (ii) if the amount of any Lender's Commitment or outstanding
Loans is less than $5.0 million, then all of such lesser amount; provided that
all simultaneous assignments to two or more funds that are Approved Funds as to
each other shall be aggregated in determining whether such minimum has been met.

                  (c) No Assignee of any Lender's rights shall be entitled to
receive any greater payment under Section 4.03 or 4.04 than such Lender would
have been entitled to receive with respect to the rights transferred, unless
such transfer is made with the Borrower's prior written consent.

                                       98

<PAGE>

                  Section 11.04 Certain Pledges. Notwithstanding any other
provision in this Agreement, (a) any Lender may at any time create a security
interest in, or pledge, all or any portion of its rights under this Agreement
and any Note held by it in favor of any Federal Reserve Bank in accordance with
Federal Reserve Board Regulation A (or any successor provision) or U.S. Treasury
Regulation 31 C.F.R. ss. 203.14 (or any successor provision), and such Federal
Reserve Bank may enforce such pledge or security interest in any manner
permitted under applicable law and (b) any Lender that is a fund that invests in
bank loans may pledge all or any portion of its rights in connection with this
Agreement to the trustee for holders of obligations owed, or securities issued,
by such fund as security for such obligations or securities, provided that any
foreclosure or other exercise of remedies by such trustee shall be subject to
the provisions of this Section 11.03 regarding assignments in all respects. No
pledge described in the immediately preceding sentence shall release any Lender
from its obligations hereunder.

                                  ARTICLE XII.

Administrative Agent; provided that if any of the actions set forth in (ii),

                                  Miscellaneous

BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

                  Section 13.02 WAIVER OF JURY TRIAL. EACH OF THE LOAN PARTIES,
THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY WAIVES TRIAL BY JURY IN ANY
JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER
SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO,
OR CONNECTED WITH THIS AGREEMENT, THE NOTES OR THE RELATIONSHIPS ESTABLISHED
HEREUNDER.

                  Section 13.03 Jurisdiction and Venue; Service of Process. (a)
Each of the Loan Parties, the Borrower, the Administrative Agent and the Lenders
each hereby irrevocably submits to the non-exclusive jurisdiction of any state

purpose of any suit, action, proceeding or judgment relating to or arising out
of any Credit Document and to the laying of venue in the Borough of Manhattan,
The City of New York. Each of the Loan Parties, the Administrative Agent and the
Lenders each hereby irrevocably waives, to the fullest extent permitted by

                  (b) Each of the Loan Parties agrees that service of process in
any such action or proceeding may be effected by mailing a copy thereof by
registered or certified mail (or any substantially similar form of mail),
postage prepaid, to it at its address set forth in Section 13.08, or to such
Loan Party at such other address of which the Administrative Agent shall have
been notified pursuant thereto. Each Loan Party further agrees that nothing
herein shall affect the right to effect service of process in any other manner
permitted by law or shall limit the right to sue in any other jurisdiction; and

                  (c) Each Loan Party waives, to the maximum extent not
prohibited by law, any right it may have to claim or recover in any legal action
or proceeding referred to in this subsection any special, exemplary, punitive or
consequential damages.

                  Section 13.04 Set off. Each Loan Party hereby authorizes each
Lender (including each Lender in its capacity as a purchaser of a participation
interest pursuant to Section 4.02(e)) upon the occurrence of an Event of Default
and at any time and from time to time during the continuance thereof, to the
fullest extent permitted by law, to set off and apply any and all deposits
(whether general or special, time or demand, provisional or final and in
whatever currency) at any time held, and other Indebtedness at any time owing,
by such Lender to or for the credit or the account of any of the Loan Parties
against any of the obligations of such Loan Party, now or hereafter existing
under any Credit Document, held by such Lender, irrespective of whether such
Lender shall have made any demand under this Agreement and although such
obligations may be unmatured. The rights of each Lender under this Section 13.04
are in addition to other rights and remedies (including other rights of set off)
which such Lender may have. Any Lender exercising its rights under this Section
13.04 shall give notice thereof to each of the Loan Parties and the
Administrative Agent concurrently with or prior to the exercise of such rights;
provided that failure to give such notice shall not affect the validity of such
exercise.

                  Section 13.05 Confidentiality. Each Lender, the L/C Issuer and
the Administrative Agent agrees (on behalf of itself and each of its affiliates,
directors, officers, employees and representatives) to keep confidential, in
accordance with their customary procedures for handling their own confidential
information, any Confidential Information; provided that the Administrative
Agent, the L/C Issuer and Lenders may: (a) make such disclosures as they are
required by law to make; (b) disclose Confidential Information on a confidential
basis to their accountants, affiliates, attorneys and other advisors in each
case who need to know such Confidential Information and to bank examiners; (c)
disclose Confidential Information to any Assignee or Participant (or prospective
Assignee or Participant) so long as such Assignee or Participant (or prospective
Assignee or Participant) agrees to keep confidential any Confidential
Information on a basis substantially similar to the basis on which the
Administrative Agent, the L/C Issuer and Lenders have agreed hereunder to keep
information confidential; (d) disclose Confidential Information to any direct or
indirect contractual counterparty in swap agreements or such contractual
counterparty's professional advisor (so long as such contractual counterparty or
professional advisor to such contractual counterparty agrees to be bound by the
provisions of this Section 13.05), and (e) make disclosures of Confidential
Information in connection with any litigation relating to enforcement of the
Credit Documents.

                  The Loan Parties acknowledge that the Lenders, L/C Issuer and
the Administrative Agent may be providing debt financing, equity capital or
other services (including financial advisory services) to other companies or
entities in respect of which the Loan Parties may have conflicting interests
regarding the transactions herein described or otherwise. However, the Lenders,
L/C Issuer and the Administrative Agent shall not furnish Confidential
Information to any of their other customers, nor will they make available to the

                  Section 13.06 Amendments and Waivers. Any provision of this
Agreement and the other Credit Documents may be amended, modified, supplemented
or waived, but only by a written amendment and the other Credit Documents or
supplement, or written waiver, signed by the Parent, the Borrower and either the
Required Lenders (and, if the rights or duties of the Administrative Agent are
affected thereby, by the Administrative Agent), or the Administrative Agent with
the consent of the Required Lenders; provided, however, that no such amendment,
modification, or waiver shall, (a) unless signed by all the Lenders, or by the
Administrative Agent with the consent of all the Lenders, (i) increase or
decrease the Commitment of any Lender or subject any Lender to any additional
obligation, (ii) reduce the principal of or rate of interest on any Loan or any
fees hereunder, (iii) postpone any scheduled payment of principal of or interest
on any Loan or any fees hereunder, (iv) postpone any reduction or termination of

any of the Guarantees granted pursuant to Article VI or any material Collateral
(unless such release is otherwise permitted under any of the Credit Documents)
or (vii) amend, modify, supplement or waive the provisions of this Section 13.06
or any other provision of this Agreement or the Credit Documents requiring the
consent of all the Lenders and (b) unless signed by Lenders holding more than
50% of the sum of the unused portion of the Total Commitment and the total
outstanding Loans for each class of Loans that is adversely affected thereby,
amend, modify, supplement or waive the provisions of Section 2.06.

                  Section 13.07 Cumulative Rights; No Waiver. Each and every
right granted to the Administrative Agent, the L/C Issuer and the Lenders
hereunder or under any other document delivered in connection herewith, or
allowed them by law or equity, shall be cumulative and not exclusive and may be
exercised from time to time. No failure on the part of the Administrative Agent,
the L/C Issuer or any Lender to exercise, and no delay in exercising, any right
will operate as a waiver thereof, nor will any single or partial exercise by the
Administrative Agent, the L/C Issuer or any Lender of any right preclude any
other or future exercise thereof or the exercise of any other right.

                  Section 13.08 Notices. (a) Any communication, demand or notice
to be given hereunder will be duly given when delivered in writing or by

such party may specify in a notice to each other party hereto. A communication,
demand or notice given pursuant to this Section 13.08 shall be addressed:

Delaware corporation ("Borrower"), each of the entities listed on the signature

     Pursuant to the Credit Agreement the Lenders may from time to time make

<PAGE>

     The Securing Party has established with [insert bank name] (together with
its successors and assigns, the "Bank") the above-referenced accounts
(collectively, the "Accounts"). Pursuant to the Pledge and Security Agreement
the Securing Party has granted to the Collateral Agent for the benefit of the
Secured Parties sole dominion and control of the Accounts. In connection with
its financing arrangements, the Securing Party has agreed with the Collateral
Agent for the benefit of the [Secured Parties under the Pledge and Security
Agreement] to create a security interest in favor of the Secured Parties in the
Accounts. In the event of any inconsistency between this letter agreement and
the terms of any other agreement between the Securing Party and Bank, the terms
of this letter agreement shall control.

     In order for the Securing Party to comply with the requirements of the
Collateral Agent and Lender under its financing arrangements with Borrower, the
Collateral Agent and the Securing Party request that Bank agree, for the benefit
of the Collateral Agent, the Secured Parties and Securing Party, as follows:

     1. Bank has established and will maintain the Accounts for the benefit of
the Securing Party and the Collateral Agent. The records of Bank do not reflect,
and it has not received any notice of, any assignment of, or pledge or security
interest in the Accounts or any checks, drafts or other instruments at any time
received for deposit in, or any amounts at any time in, the Accounts, other than
the pledge and security interest of the Collateral Agent for itself and the
ratable benefit of the Lenders referred to herein.

     2. The Securing Party has granted to the Collateral Agent for itself and
the ratable benefit of the Secured Parties a security interest in and lien upon,
and pledged to the Collateral Agent for itself and the ratable benefit of the
Secured Parties, its assets as described above, which include checks, drafts and
other instruments received for deposit in the Accounts, and all cash balance and
other amounts at any time in or attributable to the Accounts, as security for
all existing and hereafter arising obligations, liabilities and indebtedness of
Securing Parties to the Collateral Agent and the Secured Parties. Bank
acknowledges receipt of notice of the security interests and liens of the
Collateral Agent.

     3. The Accounts shall at all times be under the sole dominion and control
of the Collateral Agent. However, until Bank receives a written notice from the
Collateral Agent that an Event of Default has occurred and is continuing and
that the Collateral Agent will exercise exclusive control over each Account, the
Collateral Agent hereby authorizes the Bank to distribute to the Securing Party
any and all property on deposit from time to time in such Account and may comply
with any and all directives concerning each Account originated by the Securing
Party.

     4. At any time following receipt of a written notice from the Collateral
Agent to the Bank stating that an Event of Default has occurred and is
continuing and until receipt of a cessation notice from the Collateral Agent
stating that the Event of Default has been cured and is no longer continuing,

                                       -2-

<PAGE>

none of the officers, agents or other representatives of Securing Party or any
of its affiliates shall have any authority to withdraw any amounts from, to draw
upon or otherwise exercise any authority or powers with respect to the Accounts
and all amounts held therein except in such specific instances as may be
authorized by the Collateral Agent [in writing and the Securing Party shall not
give, and Bank shall not honor, any instruments or instructions with respect to
the Securing Party Accounts other than those approved [in writing] by Collateral
Agent.

     5. At any time following receipt of a cessation notice from the Collateral
Agent to the Bank stating that the Event of Default has been cured and is no
longer continuing and until receipt of a new written notice from the Collateral
Agent to the Bank stating that an Event of Default has occurred and is
continuing, the Collateral Agent hereby authorizes the Bank to resume making
distributions to the Securing Party of any and all property on deposit from time
to time in such Account and may comply with any and all directives concerning
each Account originated by the Securing Party, in accordance with paragraph 3
above.

     6. At such time or times as the Collateral Agent may request in writing,
Bank will promptly report to the Collateral Agent the amounts deposited in the
Accounts and will furnish to Collateral Agent any copies of bank statements,
deposit tickets, deposited items, debit and credit advices and other records
maintained by Bank under the terms of its arrangements with Securing Party (as
in effect on the date hereof). The Collateral Agent will reimburse Bank for its
reasonable expenses in providing such items to the Collateral Agent.

     7. All of the customary fees, charges and expenses in connection with the
Accounts shall be billed by Bank to Securing Party on a monthly basis. Securing
Party shall pay such fees, charges and expenses directly to Bank. The dollar
amount of any checks deposited in the Accounts and returned unpaid shall be
reimbursed by the Securing Party to Bank by check or cash on a daily basis by
the Securing Party upon notification from Bank. If Securing Party fails to
reimburse Bank for any check or fails to pay any reasonable fees, charges or
expenses in connection with the Accounts, the Collateral Agent (for the account
of Securing Party) shall reimburse Bank for such amount to the extent the
Collateral Agent received payment in respect thereof in the case of any check
returned unpaid and in any case only so long as the Collateral Agent has
received notice from Bank of the failure of Securing Party to reimburse Bank
prior to the termination of the financing arrangements of the Collateral Agent
and Lenders with Borrower. Bank shall not for any reason charge, debit or
offset, or exercise any lien rights, against any checks, drafts or other items
received for deposit in or against any amounts in or attributable to the
Accounts.

     8. To the maximum extent permitted by law, Bank shall not be liable for:
(a) events or circumstances beyond its reasonable control, or (b) indirect,
special or consequential damages, even if Bank is advised of the possibility of
damages.

cannot be changed, modified or terminated except by written agreement signed by

     WHEREAS, in order to secure the due and punctual payment of the obligations
of the Borrower to the Lenders under the Credit Agreement, the Pledgor and the
Collateral Agent have entered into a Pledge and Security Agreement dated as of
May 4, 2000 (the "Security Agreement");

     WHEREAS, capitalized terms used but not defined herein shall have the
respective meanings set forth in the Security Agreement, and the terms
"financial asset", "securities account" and "entitlement order" shall have the
respective meanings ascribed to them in the sections of the Uniform Commercial
Code as in effect at the date hereof in the State of New York (the "UCC")
referred to herein.

     NOW, THEREFORE, the parties hereto agree as follows:

     Section 1. Establishment of Securities Account. The Securities Intermediary
hereby confirms that (i) it has established [for the Pledgor] account number
___________ (the "Securities Account") [with its corporate trust department],
(ii) the Securities Account is a "securities account" as such term is defined in
Section 8-501(a) of the UCC, (iii) it shall, subject to the terms of this
Agreement, treat the Collateral Agent as entitled to exercise the rights that
comprise any financial asset or other investment property credited to the
Securities Account, and (iv) all securities, security entitlements or other

promptly credited to the Securities Account.

     Section 2. Financial Assets Election. The Securities Intermediary hereby

Account shall be treated as a "financial asset" within the meaning of Section

<PAGE>

     Section 3. Entitlement Orders. If at any time the Securities Intermediary

law or otherwise a security interest in the Securities Account or any security
entitlement credited thereto, the Securities Intermediary hereby agrees that
such security interest shall be subordinate to the security interest of the
Collateral Agent. The financial assets and other items deposited to the

any other right in favor of any person other than the Collateral Agent[, except
that the Securities Intermediary may set off all amounts due to it in respect of
its fees and expenses for the maintenance and operation of the Securities
Account].

     Section 5. Choice of Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York. Regardless of any

         hereof.

                  (f) To the knowledge of any Responsible Officer, (i) except as

provided, however that (i) to the extent that applicable law would prohibit the
attachment of a Lien hereunder, the Lien shall not attach hereunder until the
prohibition against such Lien no longer applies and (ii) to the extent that the
terms of a Permitted Lien would prohibit the attachment of a Lien hereunder to
the property subject to such Permitted Lien, the Lien shall not attach hereunder
to such property, and such property shall not constitute Collateral hereunder,
until the prohibition against such Lien no longer applies.

                  Anything herein to the contrary notwithstanding, (i) each
Securing Party shall remain liable under the contracts and agreements included

<PAGE>

to perform any of the obligations or duties of any Securing Party or thereunder
or to take any action to collect or enforce any claim for payment assigned
hereunder.

                  Section 4.   Cash Proceeds of Collateral.

                  4.01 Collateral Account. There shall be established with the
Collateral Agent a cash collateral account (the "Collateral Account") in the
name and under the sole dominion and control of the Collateral Agent into which
there shall be deposited from time to time the cash proceeds of any of the
Collateral to the extent required under the Credit Documents required to be
delivered to the Collateral Agent pursuant hereto or that the Securing Parties
are required to pledge as additional collateral security hereunder; provided
that proceeds of insurance on any of the Collateral shall not be required to be
deposited into the Collateral Account to the extent such proceeds are deposited
in an account as to which a Securities Account Control Agreement is in effect.
The balance from time to time in the Collateral Account shall constitute part of
the Collateral hereunder and shall not constitute payment of the Secured
Obligations until applied as hereinafter provided. Except as expressly provided
in the next sentence, the Collateral Agent shall remit the collected balance
outstanding to the credit of the Collateral Account to or upon the order of the
respective Securing Party as such Securing Party through the Borrower shall from
time to time instruct. However, at any time following the occurrence and during
the continuance of an Event of Default, the Collateral Agent may (and, if
instructed by the Secured Parties as specified in Section 9.01 of the Credit
Agreement, shall) in its (or their) discretion apply or cause to be applied
(subject to collection) the balance from time to time outstanding to the credit
of the Collateral Account to the payment of the Secured Obligations in the
manner specified in Section 5.09 hereof. The balance from time to time in the
Collateral Account shall be subject to withdrawal only as provided herein.

                  4.02 Proceeds of Accounts. At any time after the occurrence
and during the continuance of an Event of Default, each Securing Party shall,
upon the request of the Collateral Agent, to the extent that the Collateral
Agent does not otherwise exercise dominion and control over the depository bank
accounts of such Securing Party, instruct all account debtors and other Persons
obligated in respect of all Accounts to make all payments in respect of the
Accounts either (a) directly to the Collateral Agent (by instructing that such
payments be remitted to a post office box which shall be in the name and under
the control of the Collateral Agent) or (b) to one or more other banks in the
United States of America (by instructing that such payments be remitted to a
post office box which shall be in the name and under the control of the
Collateral Agent) under arrangements, in form and substance reasonably
satisfactory to the Collateral Agent pursuant to which such Securing Party shall
have irrevocably instructed such other bank (and such other bank shall have
agreed) to remit all proceeds of such payments directly to the Collateral Agent
for deposit into the Collateral Account if required by the Collateral Agent. All
payments made to the Collateral Agent, as provided in the preceding sentence,
shall be immediately deposited in the Collateral Account. In addition to the

                                       -9-

<PAGE>

foregoing, each Securing Party agrees that, at any time after the occurrence and
during the continuance of an Event of Default, if the proceeds of any Collateral
hereunder (including the payments made in respect of Accounts) shall be received
by it, such Securing Party shall, upon the request of the Collateral Agent, as
promptly as possible deposit such proceeds into the Collateral Account. Until so
deposited, all such proceeds shall be held in trust by such Securing Party for
the benefit of the Collateral Agent and shall not be commingled with any other
funds or property of such Securing Party.

                  4.03 Investment of Balance in Collateral Account. Amounts on
deposit in the Collateral Account shall be invested from time to time in such
Temporary Cash Investments as the respective Securing Party (or, after the
occurrence and during the continuance of an Event of Default, the Collateral
Agent) shall determine, which Temporary Cash Investments shall be held in the
name and be under the control of the Collateral Agent, provided that (a) at any
time after the occurrence and during the continuance of an Event of Default, the
Collateral Agent may (and, if instructed by the Required Lenders, shall) in its
(or their) discretion at any time and from time to time elect to liquidate any
such Temporary Cash Investments and to apply or cause to be applied the proceeds
thereof to the payment of the Secured Obligations in the manner specified in
Section 5.09 hereof and (b) if requested by the respective Securing Party
through the Borrower, such Temporary Cash Investments may be held in the name
and under the control of one or more of the Secured Parties provided that prior
thereto each such Secured Party has agreed that such Temporary Cash Investments
shall be held by each such Secured Party as a collateral sub-agent for the
Collateral Agent hereunder on terms reasonably satisfactory to the Collateral
Agent.

                  4.04 Cover for L/C Obligations. Amounts deposited into the
Collateral Account as cover for L/C Obligations pursuant to Section 2.07 of the
Credit Agreement shall be held by the Collateral Agent in a separate sub-account
(designated "L/C Obligations Sub-Account") and all amounts held in such L/C
Obligations Sub-Account shall constitute collateral security first for the L/C
Obligations outstanding from time to time and second as collateral security for
the other Secured Obligations hereunder.

                  Section 5. Further Assurances; Remedies. In furtherance of the
grant of the pledge and security interest pursuant to Section 3 hereof, the
Securing Parties hereby jointly and severally agree with each Secured Party and
the Collateral Agent as follows:

                  5.01 Delivery and Other Perfection. Each Securing Party shall:

                  (a) if any of the shares, securities, moneys or property
         required to be pledged by such Securing Party under clauses (a), (b)
         and (c) of Section 3 hereof are received by such Securing Party,
         forthwith either (i) transfer and deliver to the Collateral Agent such
         shares or securities so received by such Securing Party (together with
         the certificates for any such shares and securities duly endorsed in
         blank or accompanied by undated stock powers duly executed in blank),

                                      -10-

<PAGE>

         all of which thereafter shall be held by the Collateral Agent,
         pursuant to the terms of this Agreement, as part of the Collateral or
         (ii) take such other action as the Collateral Agent shall reasonably
         deem necessary or appropriate to duly record the Lien created
         hereunder in such shares, securities, moneys or property in said
         clauses (a), (b) and (c);

                  (b) deliver and pledge to the Collateral Agent, upon its
         request, any and all Instruments, endorsed and/or accompanied by such
         instruments of assignment and transfer in such form and substance as
         the Collateral Agent may request; provided that so long as no Event of
         Default shall have occurred and be continuing, such Securing Party may
         retain for collection in the ordinary course any Instruments received
         by such Securing Party in the ordinary course of business and the
         Collateral Agent shall, promptly upon request of such Securing Party
         through the Borrower, make appropriate arrangements for making any
         Instrument pledged by such Securing Party available to such Securing
         Party for purposes of presentation, collection or renewal (any such
         arrangement to be effected, to the extent deemed appropriate by the
         Collateral Agent, against trust receipt or like document);

                  (c) with respect to any Collateral in which any Securing Party
         has any right, title or interest that constitutes an uncertificated
         security, upon request by the Collateral Agent, such Securing Party
         shall cause the issuer thereof either (i) to register the Collateral
         Agent as the registered owner of such security or (ii) to agree in
         writing with such Securing Party and the Collateral Agent that such
         issuer will comply with instructions with respect to such security
         originated by the Collateral Agent without further consent of such
         Securing Party, such agreement to be in form and substance reasonably
         satisfactory to the Collateral Agent;

                  (d) with respect to any Collateral in which any Securing Party
         has any right, title or interest that constitutes a Security
         Entitlement, upon request by the Collateral Agent, such Securing Party
         shall cause the Securities Intermediary (as defined in the Uniform
         Commercial Code) thereof either (i) to register the Collateral Agent as
         the holder of the Security Entitlement or (ii) to agree in writing with
         such Securing Party and the Collateral Agent that such Securities
         Intermediary will comply with instructions with respect to such
         security originated by the Collateral Agent without further consent of
         such Securing Party, such agreement to be in form and substance
         reasonably satisfactory to the Collateral Agent;

                  (e) give, execute, deliver, file and/or record any financing
         statement, notice, instrument, document, agreement or other papers that
         may be necessary or desirable (in the judgment of the Collateral Agent)
         to create, preserve, perfect or validate the security interest granted
         pursuant hereto or to enable the Collateral Agent to exercise and
         enforce its rights hereunder with respect to such pledge and

                                      -11-

<PAGE>

         security interest, including, without limitation, causing any or all of
         the Stock Collateral to be transferred of record into the name of the
         Collateral Agent or its nominee (and the Collateral Agent agrees that
         if any Stock Collateral is transferred into its name or the name of its
         nominee, the Collateral Agent will thereafter promptly give to the
         respective Securing Party copies of any notices and communications
         received by it with respect to the Stock Collateral pledged by such
         Securing Party hereunder), provided that notices to account debtors in
         respect of any Accounts or Instruments shall be subject to the
         provisions of clause (i) below;

                  (f) without limiting the obligations of such Securing Party
         under Section 5.04(c) hereof, upon the acquisition after the date
         hereof by such Securing Party of any Equipment covered by a certificate
         of title or ownership, at the request of the Collateral Agent, cause
         the Collateral Agent to be listed as the lienholder on such certificate
         of title and within 120 days of such request deliver evidence of the
         same to the Collateral Agent;

                  (g) keep full and accurate books and records relating to the
         Collateral, and stamp or otherwise mark such books and records in such
         manner as the Collateral Agent may reasonably require in order to
         reflect the security interests granted by this Agreement;

                  (h) furnish to the Collateral Agent from time to time (but,
         unless an Event of Default shall have occurred and be continuing, no

         identifying and describing the Copyright Collateral, Patent Collateral
         and Trademark Collateral, respectively, and such other reports in
         connection with the Copyright Collateral, Patent Collateral and
         Trademark Collateral, as the Collateral Agent may reasonably request,

                  (i) promptly upon request of the Collateral Agent, following
         receipt by the Collateral Agent of any statements, schedules or reports
         pursuant to clause (h) above, modify this Agreement by amending Annexes
         2, 3 and/or 4 hereto, as the case may be, to include any Copyright,
         Patent or Trademark that becomes part of the Collateral under this
         Agreement;

                  (j) promptly after such Securing Party shall acquire or form
         any Subsidiary that becomes an Additional Guarantor pursuant to Section
         6.09 of the Credit Agreement, deliver to the Collateral Agent an
         amendment to Annex 1 hereto, such that after giving effect to such
         acquisition or formation, the representations set forth in Sections
         2(b) and (c) hereof (assuming that each reference to "the date hereof"
         therein referred to the date of such acquisition or formation) shall be
         true and complete as of such date; and

                                      -12-

<PAGE>

                  (k) promptly after such Securing Party shall acquire or form
         any Subsidiary that becomes an Additional Guarantor pursuant to Section
         6.09 of the Credit Agreement, cause the execution and delivery by such
         Person of a security agreement supplement in substantially the form of
         Exhibit A hereto (each a "Security Agreement Supplement") in
         consequence of which (i) such Person shall be referred to as an
         "Additional Securing Party" and shall be and become a Securing Party
         hereunder and each reference in this Agreement and the other Credit
         Documents to "Securing Party" shall also mean and be a reference to
         such Additional Securing Party, and (ii) the supplemental Annexes 1
         through 6 attached to each Security Agreement Supplement shall be
         incorporated into and become a part of and supplement Annexes 1 through
         6, respectively, hereto, and the Collateral Agent may attach such
         supplemental Annexes to such Annexes; and each reference to such
         Annexes shall mean and be a reference to such Annexes as supplemented
         pursuant to each Security Agreement Supplement.

                  5.02 Other Financing Statements and Liens. Except as otherwise
permitted under Section 8.02(c) of the Credit Agreement, without the prior
written consent of the Collateral Agent, no Securing Party shall file or suffer
to be on file, or authorize or permit to be filed or to be on file, in any
jurisdiction, any financing statement or like instrument with respect to the
Collateral in which the Collateral Agent is not named as the sole secured party
for the benefit of the Secured Parties.

                  5.03 Preservation of Rights. The Collateral Agent shall not be
required to take steps necessary to preserve any rights against prior parties to
any of the Collateral.

                  (a)   Stock Collateral.

                  (1) The Securing Parties will cause the Stock Collateral to

such shares owned by the Securing Parties except for shares of Capital Stock of
the Issuers that are Principal Subsidiaries organized in a jurisdiction outside
the United States to the extent that such shares are not required to be pledged
under Section 12.02(c) of the Credit Agreement and except to the extent that the
Issuer is (i) a Restricted Subsidiary that converts to a Principal Subsidiary, a
Designated Foreign Subsidiary or an Unrestricted Subsidiary under Article XII of
the Credit Agreement or (ii) a Principal Subsidiary that converts to a
Designated Foreign Subsidiary or an Unrestricted Subsidiary under Article XII of
the Credit Agreement.

                  (2) So long as no Event of Default shall have occurred and be
continuing, the Securing Parties shall have the right to exercise all voting,
consensual and other powers of ownership pertaining to the Stock Collateral for

                                      -13-

<PAGE>

all purposes not inconsistent with the terms of this Agreement, the Credit
Agreement, the Notes or any other instrument or agreement referred to herein or
therein, provided that the Securing Parties jointly and severally agree that
they will not vote the Stock Collateral in any manner that is inconsistent with
the terms of this Agreement, the Credit Agreement, the Notes or any such other
instrument or agreement; and the Collateral Agent shall execute and deliver to
the Securing Parties or cause to be executed and delivered to the Securing
Parties all such proxies, powers of attorney, dividend and other orders, and all
such instruments, without recourse, as the Securing Parties may reasonably
request for the purpose of enabling the Securing Parties to exercise the rights
and powers that they are entitled to exercise pursuant to this Section
5.04(a)(2).

                  (3) Unless and until an Event of Default has occurred and is
continuing, the Securing Parties shall be entitled to receive and retain any
dividends on the Stock Collateral authorized to be made pursuant to the terms of
the Credit Agreement.

                  (4) If any Event of Default shall have occurred, then so long
as such Event of Default shall continue, and whether or not the Collateral Agent
or any Secured Party exercises any available right to declare any Secured
Obligation due and payable or seeks or pursues any other relief or remedy
available to it under applicable law or under this Agreement, the Credit
Agreement, the Notes or any other agreement relating to such Secured Obligation,
and, on demand by the Collateral Agent (except where not required by law), all
dividends and other distributions on the Stock Collateral shall be paid directly
to the Collateral Agent and retained by it in the Collateral Account as part of
the Stock Collateral, subject to the terms of this Agreement, and, if the
Collateral Agent shall so request in writing, the Securing Parties jointly and
severally agree to execute and deliver to the Collateral Agent appropriate
additional dividend, distribution and other orders and documents to that end,
provided that if such Event of Default is cured, any such dividend or
distribution theretofore paid to the Collateral Agent shall, upon request of the
Securing Parties (except to the extent theretofore applied to the Secured
Obligations), be returned by the Collateral Agent to the Securing Parties.

                  (b)   Intellectual Property.

                  (1) For the purpose of enabling the Collateral Agent to
exercise rights and remedies under Section 5.05 hereof at such time as the
Collateral Agent shall be lawfully entitled to exercise such rights and
remedies, and for no other purpose, each Securing Party hereby grants to the
Collateral Agent, to the extent assignable, an irrevocable, non- exclusive
license (exercisable without payment of royalty or other compensation to such
Securing Party) to use, assign, license or sublicense any of the Intellectual
Property now owned or hereafter acquired by such Securing Party, to the extent
that such Securing Party is entitled to do so, wherever the same may be located,
including in such license reasonable access to all media in which any of the
licensed items may be recorded or stored and to all computer programs used for
the compilation or printout thereof.

                                      -14-

<PAGE>

                  (2) Notwithstanding anything contained herein to the contrary,
but subject to the provisions of Section 8.02(b) of the Credit Agreement that
limit the right of the Securing Parties to dispose of their property, so long as
no Event of Default shall have occurred and be continuing and the Collateral
Agent shall not have exercised its remedies under Section 5.05 hereof, the
Securing Parties will be permitted to exploit, use, enjoy, protect, license,
sublicense, assign, sell, dispose of or take other actions with respect to the
Intellectual Property in the ordinary course of the business of the Securing
Parties. In furtherance of the foregoing, unless an Event of Default shall have
occurred and be continuing, the Collateral Agent shall from time to time, upon
the request of the respective Securing Party through the Borrower, execute and
deliver any instruments, certificates or other documents, in the form so
requested, that such Securing Party through the Borrower shall have certified
are appropriate (in its judgment) to allow it to take any action permitted above
(including relinquishment of the license granted pursuant to clause (1)
immediately above as to any specific Intellectual Property). Further, upon the
payment in full of all of the Secured Obligations and cancellation or
termination of the Commitments and L/C Obligations or earlier expiration of this
Agreement or release of the Collateral, the Collateral Agent shall grant back to
the Securing Parties the license granted pursuant to clause (1) immediately
above. The exercise of rights and remedies under Section 5.05 hereof by the
Collateral Agent shall not terminate the rights of the holders of any licenses
or sublicenses theretofore granted by the Securing Parties in accordance with
the first sentence of this clause (2).

                  (c) Motor Vehicles. Each Securing Party shall, upon the
request of the Collateral Agent, deliver to the Collateral Agent originals of
the certificates of title or ownership for the Motor Vehicles owned by such
Securing Party with the Collateral Agent listed as lienholder and take such
other action as the Collateral Agent shall reasonably deem appropriate to
perfect the security interest created hereunder in all such Motor Vehicles.

                  5.05  Remedies; Events of Default, Etc. During the period
during which an Event of Default shall have occurred and be continuing:

                  (a) each Securing Party shall, at its own expense, and at the
         request of the Collateral Agent, assemble the Collateral owned by it at
         such time or times and place or places, reasonably convenient to both
         the Collateral Agent and such Securing Party, designated in the request
         of the Collateral Agent;

                  (b) the Collateral Agent may make any reasonable compromise or
         settlement deemed desirable with respect to any of the Collateral and
         may extend the time of payment, arrange for payment in installments, or
         otherwise modify the terms of, any of the Collateral;

                  (c) the Collateral Agent shall have all of the rights and
         remedies with respect to the Collateral of a secured party under the

                                      -15-

<PAGE>

         Uniform Commercial Code (whether or not said Code is in effect in the
         jurisdiction where the rights and remedies are asserted) and such
         additional rights and remedies to which a secured party is entitled
         under the laws in effect in any jurisdiction where any rights and
         remedies hereunder may be asserted, including, without limitation, the
         right, to the maximum extent permitted by law, to exercise all voting,
         consensual and other powers of ownership pertaining to the Collateral
         as if the Collateral Agent were the sole and absolute owner thereof
         (and each Securing Party agrees to take all such action as may be
         appropriate to give effect to such right);

                  (d) the Collateral Agent in its discretion may, in its name or
         in the name of the Securing Parties or otherwise, demand, sue for,
         collect or receive any money or property at any time payable or
         receivable on account of or in exchange for any of the Collateral, but
         shall be under no obligation to do so;

                  (e) the Collateral Agent may, upon ten (10) Business Days'
         prior written notice to the Securing Parties of the time and place,
         with respect to the Collateral or any part thereof that shall then be
         or shall thereafter come into the possession, custody or control of the
         Collateral Agent, the Secured Parties or any of their respective
         agents, sell, lease, assign or otherwise dispose of all or any part of
         such Collateral, at such place or places as the Collateral Agent deems
         best, and for cash or for credit or for future delivery (without
         thereby assuming any credit risk), at public or private sale, without
         demand of performance or notice of intention to effect any such
         disposition or of the time or place thereof (except such notice as is
         required above or by applicable statute and cannot be waived), and the
         Collateral Agent or any Secured Party or any other Person may be the
         purchaser, lessee, assignee or recipient of any or all of the
         Collateral so disposed of at any public sale (or, to the extent
         permitted by law, at any private sale) and thereafter hold the same
         absolutely, free from any claim or right of whatsoever kind, including
         any right or equity of redemption (statutory or otherwise) of the
         Securing Parties, any such demand, notice and right or equity being
         hereby expressly waived and released. In the event of any sale,
         assignment, or other disposition of any of the Trademark Collateral,
         the goodwill connected with and symbolized by the Trademark Collateral
         subject to such disposition shall be included, and the Securing Parties
         shall supply to the Collateral Agent or its designee, for inclusion in
         such sale, assignment or other disposition, all Intellectual Property
         relating to such Trademark Collateral. The Collateral Agent may,
         without notice or publication, adjourn any public or private sale or
         cause the same to be adjourned from time to time by announcement at the
         time and place fixed for the sale, and such sale may be made at any
         time or place to which the sale may be so adjourned.

The proceeds of each collection, sale or other disposition under this Section
5.05, including by virtue of the exercise of the license granted to the
Collateral Agent in Section 5.04(b)(1) hereof, shall be applied in accordance
with Section 5.09 hereof.

                                      -16-

<PAGE>

                  The Securing Parties recognize that, by reason of certain
prohibitions contained in the Securities Act of 1933, as amended, and applicable
state securities laws, the Collateral Agent may be compelled, with respect to
any sale of all or any part of the Collateral, to limit purchasers to those who
will agree, among other things, to acquire the Collateral for their own account,
for investment and not with a view to the distribution or resale thereof. The
Securing Parties acknowledge that any such private sales may be at prices and on
terms less favorable to the Collateral Agent than those obtainable through a
public sale without such restrictions, and, notwithstanding such circumstances,
agree that any such private sale shall be deemed to have been made in a
commercially reasonable manner and that the Collateral Agent shall have no
obligation to engage in public sales and no obligation to delay the sale of any
Collateral for the period of time necessary to permit the respective Issuer or
issuer thereof to register it for public sale.

                  5.06 Deficiency. If the proceeds of sale, collection or other
realization of or upon the Collateral pursuant to Section 5.05 hereof are
insufficient to cover the costs and expenses of such realization and the payment
in full of the Secured Obligations, the Securing Parties which are Guarantors or
Additional Guarantors shall remain liable for any deficiency.

                  5.07 Removals, Etc. Without at least thirty (30) days' prior
written notice to the Collateral Agent, no Securing Party shall (i) maintain any
of its books and records with respect to the Collateral at any office or
maintain its principal place of business at any place, or permit any Inventory
or Equipment to be located anywhere, other than at the address indicated beneath
the signature of the Borrower to the Credit Agreement or at one of the locations
identified in Annex 6 hereto under its name or in transit from one of such
locations to another or (ii) change its name, or the name under which it does
business, from the name shown on the signature pages hereto.

                  5.08 Private Sale. The Collateral Agent and the Secured
Parties shall incur no liability as a result of the sale of the Collateral, or
any part thereof, at any private sale pursuant to Section 5.05 hereof conducted
in a commercially reasonable manner. Each Securing Party hereby waives any
claims against the Collateral Agent or any Secured Party arising by reason of
the fact that the price at which the Collateral may have been sold at such a
private sale was less than the price that might have been obtained at a public
sale or was less than the aggregate amount of the Secured Obligations.

                  5.09 Application of Proceeds. Except as otherwise expressly
provided herein and except as provided below in this Section 5.09, the proceeds
of any collection, sale or other realization of all or any part of the
Collateral pursuant hereto, and any other cash at the time held by the
Collateral Agent under Section 4 hereof or this Section 5, shall be applied by
the Collateral Agent:

                  First, to the payment of the costs and expenses of such
         collection, sale or other realization, including reasonable

                                      -17-

<PAGE>

         out-of-pocket costs and expenses of the Collateral Agent and the fees
         and expenses of its agents and counsel, and all expenses incurred and
         advances made by the Collateral Agent in connection therewith;

                  Next, to the payment in full of the Secured Obligations, in
         each case equally and ratably in accordance with the respective amounts
         thereof then due and owing or as the Secured Parties holding the same
         may otherwise agree; and

                  Finally, to the payment to the respective Securing Parties, or
         their respective successors or assigns, or as a court of competent
         jurisdiction may direct, of any surplus then remaining.

Notwithstanding the foregoing, the proceeds of any cash or other amounts held in
the L/C Obligations Sub-Account of the Collateral Account pursuant to Section
4.04 hereof shall be applied first to the L/C Obligations outstanding from time
to time and second to the other Secured Obligations in the manner provided above
in this Section 5.09.

                  As used in this Section 5, "proceeds" of Collateral shall mean
cash, securities and other property realized in respect of, and distributions in
kind of, Collateral, including any thereof received under any reorganization,
liquidation or adjustment of debt of the Securing Parties or any Issuer of or
obligor on any of the Collateral.

                  5.10 Attorney-in-Fact. Without limiting any rights or powers
granted by this Agreement to the Collateral Agent while no Event of Default has
occurred and is continuing, upon the occurrence and during the continuance of
any Event of Default the Collateral Agent is hereby appointed the
attorney-in-fact of each Securing Party for the purpose of carrying out the
provisions of this Agreement (including, without limitation, this Section 5) and
taking any action and executing any instruments that the Collateral Agent may
deem necessary or advisable to accomplish the purposes hereof, which appointment
as attorney-in-fact is irrevocable and coupled with an interest. Without
limiting the generality of the foregoing, so long as the Collateral Agent shall
be entitled under this Section 5 to make collections in respect of the
Collateral, the Collateral Agent shall have the right and power to receive,
endorse and collect all checks made payable to the order of any Securing Party
representing any dividend, payment or other distribution in respect of the
Collateral or any part thereof and to give full discharge for the same. The
Collateral Agent is hereby authorized to prepare and file in the name of any
Securing Party any financing statements describing the Collateral and the
security interests created hereby without the signature of such Securing Party
(to the extent permitted by applicable law).

                  5.11 Perfection. Prior to or concurrently with the execution
and delivery of this Agreement, each Securing Party shall (i) execute and
deliver to the Collateral Agent for filing such financing statements and other
documents in such offices as the Collateral Agent may request to perfect the

                                      -18-

<PAGE>

security interests granted by Section 3 hereof, and (ii) deliver to the
Collateral Agent all certificates identified in Annex 1 hereto, accompanied by
undated stock powers duly executed in blank.

                  5.12 Termination. When all Secured Obligations shall have been
paid in full and the Commitments of the Secured Parties under the Credit
Agreement and all L/C Obligations shall have expired or been terminated, this
Agreement shall terminate, and the Collateral Agent shall forthwith cause to be
assigned, transferred and delivered, against receipt but without any recourse,
warranty or representation whatsoever, any remaining Collateral and money
received in respect thereof, to or on the order of the respective Securing Party
and cause to be released and canceled all licenses and rights referred to in
Section 5.04(b)(1) hereof. The Collateral Agent shall also execute and deliver
to the respective Securing Party upon such termination such Uniform Commercial
Code termination statements, certificates for terminating the Liens on the Motor
Vehicles and such other documentation as shall be reasonably requested by the
respective Securing Party to effect the termination and release of the Liens on
the Collateral.

                  5.13 Further Assurances. Each Securing Party agrees that, from
time to time upon the written request of the Collateral Agent, such Securing
Party will execute and deliver such further documents and do such other acts and
things as the Collateral Agent may reasonably request in order fully to effect
the purposes of this Agreement, including, without limitation, executing and
delivering such documents as are necessary to perfect the security interest of
the Secured Parties in claims owed to the Securing Parties by the Government of
the United States.

                  5.14 Release of Collateral. So long as no Event of Default
shall have occurred and be continuing, upon the request of any Securing Party,
at the Securing Party's expense, the Collateral Agent shall execute and deliver
to such Securing Party such instruments as such Securing Party shall reasonably
request to release the security interest of the Collateral Agent in any
Collateral pledged by any Securing Party (i) if, and to the extent, such release
is authorized pursuant to the terms of the Credit Agreement, (ii) if such
Securing Party ceases to be a Restricted Subsidiary pursuant to the provisions
of Article XII of the Credit Agreement or (iii) if requested by a Securing Party
in connection with a permitted asset disposition under the Credit Agreement;
provided that any such instruments shall be delivered, and the release
effective, only upon receipt by the Collateral Agent of a certificate from such
Securing Party certifying, in the case of clause (i) the specific provision or
provisions of the Credit Agreement authorizing such release and the satisfaction
of any conditions precedent thereto, and, in the case of clause (ii) the action
taken pursuant to Article XII and the absence of any Event of Default after
giving effect thereto.

                  5.15 Transfer of Collateral. The Collateral Agent shall have
the right, at any time in its discretion and without notice to any Securing
Party, to transfer to or to register in the name of the Collateral Agent or any
of its nominees any or all of the Instruments and Security Entitlements included

                                      -19-

<PAGE>

as Collateral, subject only to the revocable rights specified in Section
5.04(a)(2). In addition, the Collateral Agent shall have the right at any time
to exchange certificates or instruments representing or evidencing Collateral
for certificates or instruments of smaller or larger denominations.

                  Section 6.   Miscellaneous.

                  6.01 No Waiver. No failure on the part of the Collateral Agent
or any Secured Party to exercise, and no course of dealing with respect to, and
no delay in exercising, any right, power or remedy hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise by the Collateral Agent
or any Secured Party of any right, power or remedy hereunder preclude any other
or further exercise thereof or the exercise of any other right, power or remedy.
The remedies herein are cumulative and are not exclusive of any remedies
provided by law.

                  6.02 Notices. All notices, requests, consents and demands
hereunder shall be in writing and telecopied or delivered to the intended
recipient at its address specified pursuant to Section 13.08 of the Credit
Agreement and shall be deemed to have been given at the times specified in said
Section 13.08.

                  6.03 Expenses. The Securing Parties jointly and severally
agree to reimburse each of the Secured Parties and the Collateral Agent for all
reasonable costs and expenses of the Secured Parties and the Collateral Agent as
provided by Section 4.06 of the Credit Agreement.

                  6.04  Amendments, Etc. The terms of this Agreement may be
waived, altered or amended as provided by Section 13.06 of the Credit Agreement.

                  6.05 Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the respective successors and assigns of each
Securing Party, the Collateral Agent, the Secured Parties and each holder of any
of the Secured Obligations (provided, however, that no Securing Party shall
assign or transfer its rights hereunder without the prior written consent of the
Collateral Agent).

                  6.06 Captions. The captions and section headings appearing
herein are included solely for convenience of reference and are not intended to
affect the interpretation of any provision of this Agreement.

                  6.07 Counterparts. This Agreement may be executed in any
number of counterparts, all of which taken together shall constitute one and the
same instrument and any of the parties hereto may execute this Agreement by

attorneys-in-fact selected by it in good faith.

                  6.10 Severability. If any provision hereof is invalid and
unenforceable in any jurisdiction, then, to the fullest extent permitted by law,

and the Secured Parties in order to carry out the intentions of the parties
hereto as nearly as may be possible and (ii) the invalidity or unenforceability

Ladies and Gentlemen:

         Reference is made to (i) the Credit Agreement dated as of May 4, 2000
and (ii) the Pledge and Security Agreement dated as of May 4, 2000 (as amended,
amended and restated, supplemented or otherwise modified from time to time, the
"Security Agreement") made by the Securing Parties from time to time party
thereto in favor of the Collateral Agent for the Secured Parties. Terms defined
in the Credit Agreement or the Security Agreement and not otherwise defined
herein are used herein as defined in the Credit Agreement or the Security
Agreement.

                  Section 1. Grant of Security. The undersigned hereby assigns
and pledges to the Collateral Agent for the ratable benefit of the Secured
Parties, and hereby grants to the Collateral Agent for the ratable benefit of
the Secured Parties, a security interest in, all of its right, title and
interest in and to all of the Collateral of the undersigned, whether now owned
or hereafter acquired by the undersigned, wherever located and whether now or
hereafter existing or arising, including, without limitation, the property and
assets of the undersigned set forth on the attached supplemental schedules to
the Schedules to the Security Agreement.

                  Section 2.  Security for Obligations.  The pledge and
assignment of, and the grant of a security interest in, the Collateral by the
undersigned under this Security Agreement Supplement and the Security Agreement

<PAGE>

secures the payment of all Obligations of the undersigned now or hereafter
existing under or in respect of the Loan Documents, whether direct or indirect,
absolute or contingent, and whether for principal, reimbursement obligations,
interest, premiums, penalties, fees, indemnifications, contract causes of
action, costs, expenses or otherwise. Without limiting the generality of the
foregoing, this Security Agreement Supplement and the Security Agreement secures
the payment of all amounts that constitute part of the Secured Obligations and
that would be owed by the undersigned to any Secured Party under the Loan
Documents but for the fact that such Secured Obligations are unenforceable or
not allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving a Loan Party.

                  Section 3. Supplements to Security Agreement Schedules. The
undersigned has attached hereto supplemental Annexes 1 through 6 to Annexes 1
through 6, respectively, to the Security Agreement, and the undersigned hereby
certifies, as of the date first above written, that such supplemental schedules
have been prepared by the undersigned in substantially the form of the
equivalent Schedules to the Security Agreement and are complete and correct in
all material respects.

                  Section 4. Representations and Warranties. The undersigned
hereby makes each representation and warranty set forth in Section 2 of the
Security Agreement (as supplemented by the attached supplemental schedules) to
the same extent as each other Securing Party.

                  Section 5. Obligations Under the Security Agreement. The
undersigned hereby agrees, as of the date first above written, to be bound as a
Securing Party by all of the terms and provisions of the Security Agreement to
the same extent as each of the other Securing Parties. The undersigned further
agrees, as of the date first above written, that each reference in the Security
Agreement to an "Additional Securing Party" or a "Securing Party" shall also
mean and be a reference to the undersigned.

                  Section 6.  Governing Law.  This Security Agreement Supplement
shall be governed by, and construed in accordance with, the laws of the State of
New York.

                                          Very truly yours,

Guaranteed Obligations, the undersigned will promptly pay the same, without
demand or notice whatsoever, and that in the case of any extension of time of

otherwise) in accordance with the terms of such extension or renewal.

     Section II. Obligations Under the Guarantee. The undersigned hereby agrees,
as of the date first above written, to be bound as a Guarantor by all of the
terms and conditions of this Guarantee and of the guarantee contained in Article

thereunder. The undersigned further agrees, as of the date first above written,
that each reference in the Guarantee and the Credit Agreement to an "Additional
Guarantor" or a "Guarantor" shall also mean and be a reference to the
undersigned, and each reference in any other Credit Document to a "Guarantor" or
a "Loan Party" shall also mean and be a reference to the undersigned.

     Section III. Obligations Unconditional. A. The undersigned agrees that its
obligations under Section 1 of this Guarantee are absolute and unconditional,
irrespective of the value, genuineness, validity, regularity or enforceability
of the obligations of the Borrower under the Credit Agreement, the Notes or any
other agreement or instrument referred to herein or therein, or any
substitution, release of exchange of any other guarantee of or security for any
of the Guaranteed Obligations, and, to the fullest extent permitted by
applicable law, irrespective of any other circumstance whatsoever that might
otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor, it being the intent of this Section 3 that the obligations of the
undersigned hereunder shall be absolute and unconditional, joint and several,
under any and all circumstances.

     B. Without limiting the generality of the foregoing, the undersigned agrees
that the occurrence of any one or more of the following shall not alter or
impair the liability of the undersigned hereunder which shall remain absolute
and unconditional as described above:

          1. at any time or from time to time, without notice to the
undersigned, the time for any performance of or compliance with any of the
Guaranteed Obligations shall be extended, or such performance or compliance
shall be waived;

          2. any of the acts mentioned in any of the provisions of this
Guarantee, the Credit Agreement or the Notes or any other agreement or
instrument referred to herein or therein shall be done or omitted;

                                       -2-

<PAGE>

          3. the maturity of any of the Guaranteed Obligations shall be
accelerated, or any of the Guaranteed Obligations shall be modified,
supplemented or amended in any respect, or any right under this Guarantee,
the Credit Agreement or the Notes or any other agreement or instrument
referred to herein or therein shall be waived or any other Guarantee of any
of the Guaranteed Obligations or any security therefor shall be released or
exchanged in whole or in part or otherwise dealt with; or

          4. any lien or security interest granted to, or in favor of, the
Administrative Agent of any Lender or Lenders as security for any of the
Guaranteed Obligations shall fail to be perfected.

     The undersigned hereby expressly waives diligence, presentment, demand of
payment, protest and all notices whatsoever, and any requirement that the
Administrative Agent or any Lender exhaust any right, power or remedy or proceed
against the Borrower under the Credit Agreement or the Notes or any other
agreement or instrument referred to herein or therein, or against any other
Person under any other Guarantee of, or security for, any of the Guaranteed
Obligations.

     Section IV. Reinstatement. The undersigned agrees that its obligations
under this Guarantee shall be automatically reinstated if and to the extent that
for any reason any payment by or on behalf of the Borrower in respect of the
relevant Guaranteed Obligations is rescinded or must be otherwise restored by
any holder of any of such Guaranteed Obligations, whether as a result of any
proceedings in bankruptcy or reorganization or otherwise and the undersigned
jointly and severally agrees that it will indemnify the Administrative Agent and
each Lender on demand for all reasonable costs and expenses (including, without
limitation, fees of counsel) incurred by the Administrative Agent or such Lender
in connection with such rescission or restoration, including any such costs and
expenses incurred in defending against any claim alleging that such payment
constituted a preference, fraudulent transfer or similar payment under any
bankruptcy.

     Section V. Subrogation. The undersigned hereby agrees that until the
payment and satisfaction in full of all Guaranteed Obligations and the
expiration and termination of the Commitments of the Lenders under the Credit
Agreement it shall not exercise any right or remedy arising by reason of any
performance by it of its Guarantee in Section 1 of this Guarantee, whether by
subrogation or otherwise, against the Borrower or any Guarantor of any of the
Guaranteed Obligations or any security for any of the Guaranteed Obligations.

     Section VI. Remedies. The undersigned agrees that, as between itself and
the Lenders, the obligations of the Borrower under the Credit Agreement and the
Notes may be declared to be forthwith due and payable as provided in Section
9.01 of the Credit Agreement (and shall be deemed to have become automatically
due and payable in the circumstances provided in said Section 9.01) of the
Credit Agreement for purposes of Section 1 of this Guarantee notwithstanding any
stay, injunction or other prohibition preventing such declaration (or such

                                       -3-

<PAGE>

obligations from becoming automatically due and payable) as against such
Borrower and that, in the event of such declaration (or such obligations being
deemed to have become automatically due and payable), such obligations (whether
or not due and payable by such Borrower) shall forthwith become due and payable
by the undersigned for purposes of said Section 1 of this Guarantee.

     Section VII. Continuing Guarantee. The undersigned agrees that this
Guarantee is a continuing Guarantee of payment, and shall apply to all
Guaranteed Obligations whenever arising.

     Section VIII. Limitation on Guarantee Obligations. Notwithstanding any
other provision of this Guarantee or the Credit Agreement to the contrary, in
any action or proceeding involving any state corporate law or any state or
federal bankruptcy, insolvency, reorganization or other law affecting the rights
of creditors generally, the undersigned, as a Loan Party, agrees with the other
Loan Parties that if the obligations of any Loan Party under this Guarantee and
the Credit Agreement would otherwise be held or determined to be void, invalid
or unenforceable on account of the amount of its liability under this Guarantee
or Article VI of the Credit Agreement, then notwithstanding any other provision
of this Guarantee and the Credit Agreement to the contrary, the amount of such
liability shall, without any further action by such Loan Party or any other
person, be automatically limited and reduced to the highest amount that is valid
and enforceable and not subordinated to the claims of other creditors as
determined in such action or proceeding.

     Section IX. Representations and Warranties. The undersigned hereby makes
each representation and warranty set forth in Section 5.01 of the Credit
Agreement to the same extent as each other Guarantor.

     Section X. APPLICABLE LAW. THIS GUARANTEE SUPPLEMENT SHALL BE GOVERNED BY

THE RELATIONSHIPS ESTABLISHED HEREUNDER.

certified mail (or any substantially similar form of mail), postage prepaid, to
it at its address set forth in Section 13 , or to the undersigned at such other

1. This license covers the New york City primary Metropolican Statistical Area.
WinStar acquired 850 MHz of spectrum from the original license, Cellularvision,
in the fall of 1998.  The original license was partitioned.

<PAGE>

Notes:

Block A Spectrum is : 27.5-28.35 GHz, paired with 29.1-29.25 GHz. This block
also includes 31.075-31.225 GHz Block B Spectrum is: 31.0-31.075 GHz, paired
with 31.225-31.3 GHz

3.   Winstar also operates a number of point-to-point microwave facilities
     (i.e., links) in bands other than the 38 GHz and 28 GHz bands, including in
     the 10 GHz and 18 GHz bands. No individual such facility is material to
     Consolidated Group.

4.   Section 101.17 of the FCC's rules provides that 38 GHz licensees must
     demonstrate substantial service at the time of license renewal. Although
     the FCC did not adopt specific buildout criteria for 38 GHz licensees, it
     has stated that buildout of four wireless point-to-point links per million
     population would constitute substantial service for a traditional
     point-to-point licensee. However, Winstar's business plan is not that of a
     traditional point-to-point licensee. Winstar has made and is continuing to
     make substantial investment in developing a national telecommunications
     business and infrastructure. We believe a national investment and our
     ongoing operations are sufficient to demonstrate substantial service for
     all our 38 GHz licenses. As a result, we expect that our 38 GHz licenses
     will be renewed by the FCC, but we cannot be certain of that conclusion.

o    On February 10, 1998, the FCC granted additional channels for the following
     Winstar 38 GHz licenses: Atlanta (Call Sign WPOP581), Buffalo (WMN322),
     Cincinnati (WMN324), Dallas (WPOP580), Houston (WMN329), Miami (WMN332),
     New York (WMN337), St. Louis (WMN344), Seattle (WMN318), Spokane (WMN343),
     and Tampa (WMN346). On March 12, 1998, several parties filed petitions for
     reconsideration of each of these grants, with the exception of the Seattle
     grant. On October 22, 1999, the FCC denied some of the petitions for
     reconsideration and affirmed the grants.2 Parties have filed an application
     for review requesting that the FCC reconsider the grants. Winstar filed an
     opposition to this application. In addition, on March 9, 1998, several
     parties filed petitions for reconsideration of the 38 GHz Order, alleging,
     among other things, that the February 10, 1998, license grant to Winstar
     were in violation of the Commission's processing rules. Winstar filed a
     consolidated opposition to these petitions. The FCC denied these petitions
     on August 23, 1999. However, several parties have filed petitions for
     review in the U.S. Court of Appeals for the D.C. Circuit.

o    On December 29, 1999, the FCC granted in part five Winstar applications
     requesting additional channels in the following areas: Baltimore (WMN320),
     New York (WMN335 & WMN336), Philadelphia (WMN338), and Washington, D.C.
     (WMN347). On January 24, 2000, several parties filed petitions for
     reconsideration of each of these grants. Winstar filed an opposition to
     these petitions which remains pending.

o    In addition, on March 15, 2000, the FCC granted in whole or in part twelve
     Winstar applications for additional channel pairs in San Diego (WMN341),
     Milwaukee (WMN333), Kansas City (WMN330), Cleveland (WMN325), Detroit
     (WMN328), Tacoma (WMN345), Phoenix (WMN339), Boston (WMN321), Minneapolis
     (WMN334), Denver (WMN327), Pittsburgh (WMN340), and Chicago (WMN323). These
     channel grants were conditioned by the Commission on the final outcome of
     the pending proceedings described in the above two paragraphs. On March 15,
     2000, the FCC also granted Winstar a channel pair in Santa Rosa, California
     (WPOM875). Grant of this application was conditioned on the outcome of a
     pending petition for reconsideration.

o    On October 23, 1997, DCT Communications, Inc. filed a petition for
     reconsideration seeking revocation of Winstar's license in Ft. Lauderdale,
     Florida (WPNI271). On January 21, 1999, the Commission released an order
     denying DCT's petition for reconsideration. In response, DCT filed an
     application for review which Winstar opposed. The Commission denied the
     application for review on February 22, 2000; however, DCT has requested
     that the FCC reconsider its decision.

o    Winstar operates a number of point-to-point microwave facilities (i.e.,
     links) in the 17.7-19.7 GHz (18 GHz) band. In an ongoing proceeding, the
     FCC has proposed the relocation of a number of these facilities to
     accommodate satellite services. However, the FCC has proposed that
     relocated microwave operators should receive compensation for such
     relocation. A final FCC Order in this proceeding is expected later this
     year.

                                  INTRODUCTION

      1.1  Establishment.  The Storage  Technology  Corporation  (the "Company")
original 1995 Equity  Participation  Plan (the "Original Plan") was effective as
of March 8,  1995,  the  date it was  adopted  by the  Board of  Directors  (the
"Board") of the Company.  The Original Plan was approved by  stockholders of the
Company on May 24,  1995.  The  Original  Plan was  amended in  September  1996,
February  1997,  March  1998,  March  1999  and  March  2000  (individually,  an
"Amendment"), in each instance receiving stockholder approval when required. The
Company has determined that, for sake of clarity, it is advisable to incorporate
all the  Amendments  to the Original  Plan into this  Amended and Restated  1995
Equity Participation Plan (the "1995 Plan").

      Effective as provided in Section 22, the Company hereby establishes a plan
of  long-term  stock-based   compensation  incentives  for  selected  employees,
directors and consultants of the Company and its affiliated corporations.

     1.2  Purpose.  The  purpose  of the  1995  Plan  is to  provide  employees,
directors and consultants selected for participation in the 1995 Plan with added
incentives to continue in the service of the Company and its  affiliates  and to
create in such  employees,  directors and  consultants a more direct interest in
the  future  success  of  the  operations  of the  Company  and  its  affiliated
corporations by relating incentive  compensation to the achievement of long-term
corporate  economic  objectives.  The 1995 Plan is also  designed to attract key
employees,  directors and consultants  and to retain and motivate  participating
employees,  directors and  consultants  by providing an  opportunity  for equity
investment in the Company.

      1.3 No  Effect on 1987  Plan  Options.  Options  granted  pursuant  to the
Storage Technology  Corporation 1987 Equity Participation Plan (the "1987 Plan")
shall be governed by the terms and provisions of the option agreements  covering
such grants and by the provisions of the 1987 Plan.

                               PLAN ADMINISTRATION

3.1 Administration  Generally.  The 1995 Plan shall be administered by the Board

      (m) shall  establish  such other  terms and  requirements  of the  various
compensation  incentives under the 1995 Plan as the Committee may deem necessary
or desirable and consistent with the terms of the 1995 Plan.

      The Committee  shall  determine the form or forms of the  agreements  with
Participants, which shall evidence the particular provisions, terms, conditions,
rights and duties of the Company and the Participants  with respect to Incentive
Stock Options,  Non-Qualified  Options,  Stock Appreciation Rights, Common Stock
Equivalent and Restricted  Stock Awards granted pursuant to the 1995 Plan, which
provisions need not be identical except as may be provided herein. The Committee

purposes of the 1995 Plan as it may deem proper and in the best interests of the
Company.  The  Committee  may  correct  any  defect or supply  any  omission  or
reconcile any  inconsistency  in the 1995 Plan or in any agreement  entered into
hereunder  in the manner and to the extent it shall deem  expedient to carry the
1995  Plan  into  effect,  and it  shall be the  sole  and  final  judge of such
expediency.  No  member  of the  Committee  shall be  liable  for any  action or
determination made in good faith. The determinations,  interpretations and other
actions of the  Committee  pursuant to the  provisions of the 1995 Plan shall be
binding and conclusive for all purposes and on all persons,  subject only to the
review  and  control  of the  Board on all Plan  matters,  except  selection  of
Participants.

grants of Stock Options,  Stock Appreciation Rights,  Restricted Stock Awards or
other  Common  Stock or Common  Stock  Equivalent  awards under the 1995 Plan to
Employees  who  are  also  officers  or  Directors,   the  1995  Plan  shall  be
administered by:

      (a) the Board,  if the Board may  administer  the 1995 Plan and still have
transactions under the 1995 Plan qualify for exemption under Rule 16b-3; or

      (b) a Committee designated by the Board to administer the 1995 Plan, which
Committee  shall be constituted (i) in such a manner as to permit awards granted
under the 1995 Plan to qualify for exemption under Rule 16b-3 and (ii) in such a
manner as to satisfy applicable laws. <PAGE>

      3.4 Administration  With Respect to Other Persons.  With respect to grants
of Stock Options,  Stock Appreciation  Rights,  Restricted Stock Awards or other
Common Stock or Common  Stock  Equivalent  awards to  Employees  who are neither
Directors nor officers, the 1995 Plan shall be administered by:

      (a)   the Board;  or

      (b) a  Committee  designated  by  the  Board,  which  Committee  shall  be
constituted in such a manner as to satisfy applicable laws.

      3.5 Committee Composition. Once a Committee has been appointed pursuant to
Section 3.3 or 3.4, such  Committee  shall  continue to serve in its  designated
capacity until otherwise  directed by the Board. From time to time the Board may
increase  the size of any  Committee  and appoint  additional  members  thereof,
remove members (with or without  cause) and appoint new members in  substitution
therefor, fill vacancies (however caused) or remove all members of the Committee
and thereafter  directly  administer  the Plan,  all to the extent  permitted by
applicable laws and, in the case of a Committee  appointed under Section 3.3, to
the extent  permitted  by Rule 16b-3 as it applies to  transactions  intended to
qualify thereunder as exempt transactions.

                                   SECTION IV

      4.1 Number of Shares.  Twenty Three  Million Five Hundred  Fifty  Thousand
(23,550,000)  shares of Common Stock are  authorized for issuance under the 1995
Plan in  accordance  with the  provisions  of the 1995 Plan and  subject to such
restrictions  or other  provisions  as the  Committee may from time to time deem
necessary or appropriate.  This authorization may be increased from time to time
by approval of the Board and the  stockholders of the Company.  Shares of Common
Stock that are issued upon exercise of Incentive  Stock  Options,  Non-Qualified
Options,  or Stock  Appreciation  Rights or pursuant to MBO Payments,  shares of
Common Stock that are issued as Restricted Stock Awards,  shares of Common Stock
that are issued in  connection  with  Common  Stock  Equivalents,  and shares of
Common Stock that are issued pursuant to a plan adopted  pursuant to Section 15,
shall be  applied  to reduce  the  number of  shares of Common  Stock  remaining
available for future issuance under the 1995 Plan.

      4.2  Unused  and  Forfeited  Stock.  Any  shares of Common  Stock that are
subject to an Incentive Stock Option or a  Non-Qualified  Option that expires or
for any reason is terminated  unexercised,  and with respect to which no related
Stock Appreciation Right has been exercised, any shares of Common Stock that are
subject to Common Stock Equivalents or to a Restricted Stock Award and that are

<PAGE>

forfeited (the  "Forfeited  Restricted  Stock"),  and any shares of Common Stock
that for any other reason are not issued to a Participant  (not including shares
withheld  pursuant to Section 20.2) or are forfeited (if  forfeited,  the "Other
Forfeited Stock"),  shall automatically  become available for use under the 1995
Plan;  provided,  however,  that (i) no shares of Forfeited  Restricted Stock or
Other  Forfeited  Stock may be subject to Incentive  Stock Options and (ii) such
shares shall not be returned to the 1995 Plan if prohibited by Rule 16b-3.

      4.3 Capital  Adjustments.  (a) Changes in  Capitalization.  Subject to any
required  action by the  stockholders  of the  Company,  the number of shares of
Common Stock covered by each outstanding Stock Option,  Stock Appreciation Right
and Common Stock Equivalent ("Rights"), and the number of shares of Common Stock
that have been  authorized  for issuance under the Plan but as to which no Stock
Options,  Stock  Appreciation  Rights or Common Stock  Equivalents have yet been
granted or that have been returned to the Plan upon  cancellation  or expiration
of a Stock Option,  Stock  Appreciation  Right or Common Stock  Equivalents (the
"Shares  Available for Future Grant"),  as well as the price per share of Common
Stock  covered by each  outstanding  Stock Option or Stock  Appreciation  Right,
shall be proportionately  adjusted for any increase or decrease in the number of
issued and  outstanding  shares of Common  Stock  resulting  from a stock split,
reverse stock split,  stock  dividend,  combination or  reclassification  of the
Common  Stock,  or any other  increase  or  decrease in the number of issued and
outstanding  shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the  Company  shall  not be deemed to have been  "effected  without  receipt  of
consideration."  Such  proportionate  adjustment shall be made by the Committee,
whose  determination  in that respect  shall be final,  binding and  conclusive.
Except as  expressly  provided  herein,  no issuance by the Company of shares of
stock of any class, or securities  convertible into or exercisable for shares of
stock of any class,  shall affect,  and no adjustment by reason thereof shall be
made with  respect to, the number of Shares  Available  for Future  Grant or the
number or price of shares of Common Stock subject to  outstanding  Stock Options
or Stock Appreciation Rights.

      (b) Dissolution or Liquidation.  In the event of the proposed  dissolution
or  liquidation  of the  Company,  to the  extent  that a Stock  Option or Stock
Appreciation  Right  has  not  been  previously  exercised,  it  will  terminate
immediately  prior to the  consummation of such proposed  action.  The Committee
may, in the exercise of its sole discretion in such instances,  declare that any
Stock Option or Stock  Appreciation  Right shall terminate as of a date fixed by
the Committee and give each  Participant  the right to exercise his or her Stock
Option or Stock Appreciation  Right in whole or in part,  including with respect
to shares as to which the Stock  Option or Stock  Appreciation  Right  would not
otherwise be exercisable.  Unless determined otherwise by the Committee,  Common
Stock Equivalents shall convert into shares of Common Stock immediately prior to
the consummation of any such dissolution or liquidation.
<PAGE>

      (c) Merger or Asset Sale. In the event of a merger or consolidation of the
Company with or into another  corporation,  or the sale of all or  substantially
all  of  the  assets  of the  Company,  each  outstanding  Stock  Option,  Stock
Appreciation  Right and Common Stock  Equivalent may be assumed or an equivalent
Stock  Option,  Stock  Appreciation  Right or  Common  Stock  Equivalent  may be
substituted  by the  successor  corporation  or a parent  or  subsidiary  of the
successor  corporation.  The  Committee  may,  in  lieu of  such  assumption  or
substitution  of Stock  Options  and  Stock  Appreciation  Rights,  provide  for
Optionees  to have the  right  to  exercise  his or her  Stock  Option  or Stock
Appreciation  Right in whole or in part,  including with respect to shares as to
which it would not otherwise be  exercisable.  If the  Committee  makes a Common
Stock Equivalent convertible into shares of Common Stock or makes a Stock Option
or Stock Appreciation Right exercisable in lieu of assumption or substitution in
the event of a merger,  consolidation  or sale of assets,  the  Committee  shall
notify the Participants and, in the case of a Stock Option or Stock Appreciation
Right,  shall  notify the Optionee  that the Stock Option or Stock  Appreciation
Right shall be fully  exercisable for a period of thirty (30) days from the date
of such notice, and the Stock Option or Stock Appreciation Right shall terminate
upon the  expiration  of such period.  For the purposes of this  paragraph,  the
Stock  Option,  Stock  Appreciation  Right or Common Stock  Equivalent  shall be
considered  assumed if,  following the merger,  consolidation or sale of assets,
the Stock Option,  Stock  Appreciation  Right or Common Stock Equivalent confers
the right to purchase or receive,  for each share of Common Stock subject to the
Stock Option,  Stock Appreciation  Right or Common Stock Equivalent  immediately
prior to the merger, consolidation or sale of assets, the consideration (whether
stock,   cash  or  other  securities  or  property)   received  in  the  merger,
consolidation  or sale of assets by holders of Common  Stock for each share held
on the effective date of the transaction  (and, if holders were offered a choice
of consideration,  the type of consideration chosen by the holders of a majority
of the  outstanding  shares);  provided,  however,  that if  such  consideration
received in the merger,  consolidation  or sale of assets was not solely  common
stock of the successor  corporation  or its parent,  the Committee may, with the
consent  of the  successor  corporation,  provide  for the  consideration  to be
received upon  conversion  of a Common Stock  Equivalent or upon the exercise of
the Stock  Option or Stock  Appreciation  Right,  for each share of Common Stock
subject to the Stock Option, Stock Appreciation Right or Common Stock Equivalent
to be solely  common stock of the successor  corporation  or its parent equal in
fair market value to the per share  consideration  received by holders of Common
Stock in the merger, consolidation or sale of assets.

                                  PARTICIPATION

      5.1  Eligibility.  Participants  in the 1995 Plan shall be those  Eligible
Employees,  Directors and Consultants who, in the judgment of the Committee, are
performing,  or during the term of their  service to the Company are expected to
perform,  vital  services in the  management,  operation and  development of the
Company  or an  Affiliated  Corporation,  and  significantly  contribute  or are
expected to significantly  contribute to the achievement of long-term  corporate
economic objectives.  Participants who are Employees may be granted from time to
time one or more  Incentive  Stock Options  (with or without Stock  Appreciation
Rights), and Participants (whether or not they are Employees) may be granted one
or more Non-Qualified  Options (with or without Stock Appreciation  Rights), one
or more  Restricted  Stock  Awards,  one or more MBO  Payments  in Common  Stock
Equivalents or in shares of Common Stock,  Common Stock equivalents  pursuant to
Section 12, and one or more other Common Stock or Common Stock Equivalent awards
pursuant to Section 15; provided,  however,  that the grant of each such option,
right,  award or payment  shall be  separately  approved by the  Committee,  and
receipt  of one such  option,  right,  award or  payment  shall  not  result  in
automatic  receipt  of  any  other  option,   right,  award  or  payment.   Upon
determination by the Committee that a Stock Option,  Stock  Appreciation  Right,
Restricted  Stock  Award,  MBO  Payment or other  Common  Stock or Common  Stock
Equivalent  award is to be granted to a  Participant,  written  notice  shall be
given to such  person,  specifying  the  terms,  conditions,  rights  and duties
related  thereto.  Each Participant  shall, if required by the Committee,  enter
into an  agreement  with  the  Company,  in such  form  as the  Committee  shall
determine and as is consistent with the provisions of the 1995 Plan,  specifying
such terms,  conditions,  rights and duties.  Stock Options,  Stock Appreciation
Rights,  Restricted Stock Awards,  MBO Payments and other Common Stock or Common
Stock  Equivalent  awards shall be deemed to be granted as of the date specified
in the grant  resolution of the  Committee,  which date shall be the date of any
related  agreement  with the  Participant.  In the  event  of any  inconsistency
between the  provisions  of the 1995 Plan and any such  agreement  entered  into
hereunder, the provisions of the 1995 Plan shall govern.

      5.2 Limitations.  The following limitations shall apply to grants of Stock
Options and Stock Appreciation Rights to Participants:

      (a)(i) Except as set forth in Section  5.2(a)(ii)  hereof,  no Participant
shall be granted,  in any fiscal year of the  Company,  Stock  Options and Stock
Appreciation  Rights to purchase more than two million  (2,000,000)  shares (the
"Individual Limit").

      (ii) No individual  who is a  newly-hired  employee of the Company (a "New
Hire") shall be granted in the fiscal year (the "Initial  Fiscal Year") in which
he or she became a New Hire,  Stock  Options  and Stock  Appreciation  Rights to
purchase shares more than twice the Individual Limit. <PAGE>

      (b) If a Stock Option or Stock  Appreciation Right is canceled in the same
fiscal  year of the Company in which it was  granted  (other than in  connection
with a transaction described in Section 4.3), the canceled Stock Option or Stock
Appreciation  Right  shall be  counted  against  the limit set forth in  Section
5.2(a).

      (c) Incentive Stock Options may not be granted to Outside  Directors or to
Consultants.

      5.3 Rule 16b-3. Stock Options, Stock Appreciation Rights, Restricted Stock
Awards,  MBO Payments and other Common Stock or Common Stock  Equivalent  awards
granted to Participants who are subject to Section 16 of the Securities Exchange
Act of 1934, as amended (the  "Exchange  Act"),  must comply with the applicable
provisions  of Rule  16b-3 and  shall  contain  such  additional  conditions  or
restrictions as may be required  thereunder to qualify for the maximum exemption
from Section 16 of the Exchange Act with respect to 1995 Plan transactions.

                                   SECTION VI

                                  STOCK OPTIONS

      6.1 Grant of Stock Options.  Coincident with or following  designation for
participation  in the 1995 Plan, a Participant  may be granted one or more Stock
Options.  The Committee in its sole  discretion  may  designate  whether a Stock
Option granted to an Employee is to be considered an Incentive Stock Option or a
Non-Qualified Option. The Committee may grant both an Incentive Stock Option and
a  Non-Qualified  Option to the same  Employee at the same time or at  different
times. Incentive Stock Options and Non-Qualified Options, whether granted at the
same or  different  times,  shall be  deemed to have been  awarded  in  separate
grants,  shall be clearly  identified,  and in no event will the exercise of one
Stock  Option  affect the right to exercise any other Stock Option or affect the
number  of shares of Common  Stock  for  which  any other  Stock  Option  may be
exercised. All Stock Options granted to Participants who are not Employees shall
be Non-Qualified Options.

      6.2 Manner of Stock Option Exercise.  A Stock Option may be exercised by a
Participant  in whole or in part from time to time,  subject  to the  conditions
contained  herein,  (i) by delivery of written notice of exercise to the Company
at  its  principal  office  in  Louisville,   Colorado   (Attention:   Corporate
Secretary),  in person or through  mail,  facsimile or  electronic  mail,  or by
delivery of notice of exercise in such other method as has been  approved by the
Committee, and (ii) by paying in full, with the written notice of exercise or at
such other time as the Committee may  establish,  the total exercise price under
the Stock Option for the shares being purchased.  Such notice shall be in a form
satisfactory to the Committee and shall specify the particular Stock Option (or

<PAGE>

portion  thereof) that is being  exercised and the number of shares with respect
to which the Stock Option is being  exercised.  The exercise of the Stock Option
shall be deemed effective upon receipt of such notice by the Corporate Secretary
and payment to the Company.  As soon as practicable after the effective exercise
of the  Stock  Option,  and  upon  satisfaction  of all  applicable  withholding
requirements  pursuant to Section 20, the  Participant  shall be recorded on the
stock transfer books of the Company as the owner of the shares purchased and the
Company  shall deliver to the  Participant  one or more duly issued and executed
stock certificates evidencing such ownership.

      6.3 Payment of Stock Option Exercise Price. At the time of the exercise of
a Stock Option,  payment of the total Stock Option exercise price for the shares
to be purchased  shall be made in the manner  specified in the option  agreement
relating to such Stock  Option,  which may  include any or all of the  following
methods of payment:

      (a)   in cash or by check;

      (b) by transfer  from the  Participant  to the Company of shares of Common
Stock (other than shares of Common Stock that the  Committee  determines by rule
may not be used to exercise  Stock  Options) with a then current  aggregate Fair
Market Value equal to the total Stock Option exercise price;

      (c) delivery to the Company of: (i) a properly  executed  exercise notice,
(ii)  irrevocable  instructions  to a broker to sell a sufficient  number of the
shares being  exercised to cover the exercise  price and to promptly  deliver to
the Company the amount of sale proceeds  required to pay the exercise  price and
any  required tax  withholding  relating to the  exercise,  and (iii) such other
documentation as the Committee and the broker shall require to effect a same-day
exercise and sale;

      (d) delivery to the Company of (i) a properly  executed  exercise  notice,
(ii) irrevocable instructions to a broker or other third party acceptable to the
Company to hold the  shares  being  exercised  as  collateral  for a loan to the
Optionee of an amount  sufficient  to cover the  exercise  price and to promptly
deliver to the Company the amount of loan proceeds  required to pay the exercise
price and any required tax  withholding  relating to the exercise and (iii) such
other  documentation  as the Committee and the broker or other third party shall
require to effect the transaction;

      (e) a reduction in the amount of any Company  liability  to the  Optionee,
including any liability  attributable  to the  Optionee's  participation  in any
Company-sponsored deferred compensation program or arrangement;

      (f)   any combination of the foregoing methods of payment; or
<PAGE>

      (g) such other  consideration  and method of payment  for the  issuance of
Shares to the extent  permitted by applicable laws, rules and regulations and by
the agreement relating to the Stock Option being exercised.

      In the event that the option  agreement  does not specify  the  acceptable
methods of  payment of the  exercise  price,  payment  may be made by any of the
methods specified in clauses (a) through (c), inclusive, of this Section 6.3, or
any combination of such methods of payment.

      6.4  Stockholder  Privileges.  No  Participant  shall have any rights as a
stockholder with respect to any shares of Common Stock covered by a Stock Option
until the Participant  becomes the holder of record of such Common Stock, and no
adjustments  shall be made for dividends or other  distributions or other rights
as to which there is a record date preceding the date such  Participant  becomes
the holder of record of such Common Stock.

                                   SECTION VII

                             INCENTIVE STOCK OPTIONS

      7.1 Incentive Stock Option Exercise Price.  The per share price to be paid
by a  Participant  at the time an Incentive  Stock Option is exercised  shall be
determined by the Committee at the time an Incentive Stock Option is granted (or
deemed to have been granted under  applicable tax rules),  but in no event shall
such exercise price be less than:

      (a) one  hundred  percent  of the  Fair  Market  Value,  on the  date  the
Incentive  Stock  Option  is  granted  (or  deemed to have  been  granted  under
applicable  tax  rules),  of one share of the stock to which such  Stock  Option
relates; or

      (b) one hundred and ten percent of the Fair Market Value,  on the date the
Incentive  Stock  Option  is  granted  (or  deemed to have  been  granted  under
applicable  tax  rules),  of one share of the stock to which such  Stock  Option
relates if, at the time the Incentive  Stock Option is granted,  the Participant
owns,  directly or indirectly (as  determined  pursuant to Section 424(d) of the
Internal  Revenue Code),  ten percent or more of the total combined voting power
of all classes of stock of the Company or of any Affiliated  Corporation (such a
Participant is referred to as a "10% Holder").

      7.2 Number of Option Shares.  The number of shares of Common Stock subject
to an Incentive  Stock Option shall be  designated  by the Committee at the time
the Committee decides to grant an Incentive Stock Option.
<PAGE>

      7.3 Aggregate Limitation of Stock Exercisable Under Options. To the extent
the aggregate  Fair Market Value,  determined as of the time an Incentive  Stock
Option is granted, of the shares of Common Stock with respect to which Incentive
Stock  Options  are  exercisable  for the first time by an Option  Holder in any
calendar  year  under the 1995 Plan or  otherwise,  granted by the  Company  and
Affiliated  Corporations,  exceeds  $100,000,  such excess shall be treated as a
Non-Qualified Option.

      7.4  Duration of  Incentive  Stock  Options.  The period  during  which an
Incentive Stock Option may be exercised shall be fixed by the Committee,  but in
no event shall such period be more than ten years from the date the Stock Option
is granted,  or, in the case of Participants who are 10% Holders as described in
Section  7.1(b),  five  years  from the date the  Stock  Option is  granted.  No
Incentive Stock Option with respect to which Stock Appreciation Rights have been
granted may be exercised during the six-month period following the date on which
such Stock Option was granted.  Upon the expiration of such exercise period, the
Incentive  Stock  Option,  to the extent not then  exercised,  shall  terminate.
Except as otherwise  provided in Section 11, all Incentive Stock Options granted
to a Participant hereunder shall terminate and may no longer be exercised if the
Participant ceases to be an Employee.

      7.5  Restrictions on Exercise of Incentive Stock Options.  Incentive Stock
Options may be granted subject to such restrictions as to the timing of exercise
of all or various portions thereof as the Committee may determine at the time it
grants Incentive Stock Options to Participants.

      7.6  Disposition of Stock  Acquired  Pursuant to the Exercise of Incentive
Stock Options ? Withholding. In the event that a Participant makes a disposition
(as defined in Section 424(c) of the Internal  Revenue Code) of any Common Stock
acquired  pursuant to the  exercise of an  Incentive  Stock  Option prior to the
expiration  of two years from the date on which the  Incentive  Stock Option was
granted or prior to the  expiration of one year from the date on which the Stock
Option was exercised,  the Participant  shall send written notice to the Company
at its principal office in Louisville, Colorado (Attention: Corporate Secretary)
of the date of such disposition, the number of shares disposed of, the amount of
proceeds  received from such disposition and any other  information  relating to
such disposition as the Company may reasonably  request.  The Participant shall,
in the  event of such a  disposition,  make  appropriate  arrangements  with the
Company to provide for the amount of additional withholding required by federal,
state and local income and other tax laws. <PAGE>

                                  SECTION VIII

                              NON-QUALIFIED OPTIONS

      8.1  Option  Exercise  Price.  The  per  share  price  to be  paid  by the
Participant at the time a Non-Qualified  Option is exercised shall be determined
by the  Committee at the time the Stock Option is granted or amended,  but in no
event shall such  exercise  price per share be less than one hundred  percent of
the Fair Market  Value of one share of Common Stock on the date the Stock Option
is granted or amended.

      8.2 Number of Option Shares.  The number of shares of Common Stock subject
to a  Non-Qualified  Option shall be designated by the Committee at the time the
Committee decides to grant a Non-Qualified Option.

      8.3 Duration of  Non-Qualified  Options;  Restrictions  on  Exercise.  The
period during which a Non-Qualified Option may be exercised, and the installment
restrictions on option  exercise  during such period,  if any, shall be fixed by
the Committee, but in no event shall such period be more than ten years from the
date the Stock Option is granted,  and no  Non-Qualified  Option with respect to
which Stock  Appreciation  Rights have been granted may be exercised  during the
six-month period  immediately  following the date on which such Stock Option was
granted.  Upon the expiration of such exercise period, the Non-Qualified Option,
to the extent not then exercised, shall terminate.  Except as otherwise provided
in Section 11, all  Non-Qualified  Options  granted to a  Participant  hereunder
shall terminate and may no longer be exercised if the  Participant  ceases to be
an Employee, Director or Consultant.

                                   SECTION IX

                            STOCK APPRECIATION RIGHTS

      9.1  Grant of  Rights.  A Stock  Appreciation  Right may be  granted  to a
Participant  in  conjunction  with any Incentive  Stock Option or  Non-Qualified
Option granted to such Participant,  as determined by the Committee,  (a) at the
time of the grant of such Stock Option in the case of an Incentive  Stock Option
or (b) at the time of grant,  or at any  subsequent  time during the term of the
Stock Option, in the case of a Non-Qualified Option. Once granted, the term of a
Stock Appreciation Right shall be equal to the term of its related Stock Option.
Upon  exercise of a Stock  Appreciation  Right by a  Participant  for a share of
Common Stock,  the related Stock Option shall be terminated with respect to such
share.   Incentive  Stock  Options  and  Non-Qualified   Options  shall  not  be
exercisable with respect to shares of Common Stock for which Stock  Appreciation
Rights have been exercised.  Upon such Stock  Appreciation  Right exercise,  the
Participant  shall be  entitled  to  receive  the  economic  value of such Stock
Appreciation Right determined in the manner prescribed in Section 9.2.

      9.2 Exercise of Stock Appreciation Rights. Stock Appreciation Rights shall
be subject to such terms and conditions  consistent with other provisions of the
1995  Plan as may be  determined  from time to time by the  Committee  and shall
include the following: <PAGE>

      (a) A Stock Appreciation Right shall be exercisable,  in whole or in part,
at such time or times and only to the extent  that the Stock  Option to which it
relates  shall be  exercisable;  provided,  however,  that,  except as otherwise
provided in Section 11, no Stock  Appreciation Right shall be exercisable during
the six-month period following the date of its grant. A Stock Appreciation Right
shall be  exercised  by the  giving of  notice  in the same  manner as the Stock
Option to which it relates may be exercised.

      (b) Upon the exercise of a Stock  Appreciation  Right, a Participant shall
be entitled to receive the economic value  thereof,  which shall be equal to (i)
the excess of the then Fair Market  Value of one share of Common  Stock over the
exercise  price per share  specified in the related Stock Option,  multiplied by
(ii) the number of shares in respect  of which the Stock  Appreciation  Right is
being exercised.

      (c)  The  Committee  shall,  in  the  agreement   relating  to  the  Stock
Appreciation Right, either (i) specify the form in which payment of the economic
value of exercised  Stock  Appreciation  Rights will be made to the  Participant
upon exercise  thereof (i.e.,  cash,  Common Stock,  or a specified  combination
thereof)  or (ii) grant the  Participant  the right to elect to receive  cash in
full or partial payment of such economic value, at the Participant's discretion.
If the agreement  relating to the Stock  Appreciation Right does not so specify,
then the Participant shall have the right to elect cash or Common Stock,  Common
Stock  Equivalents  or any  combination  thereof.  If the  Participant is not an
"officer" or "director" of the Company,  as those terms are defined in the rules
under  Section 16 of the  Exchange  Act, at the time of grant or exercise of the
Stock  Appreciation  Right,  then the  Committee  may retain the right to either
consent to or disapprove of Participant's elected method of payment.

      9.3  Stockholder  Privileges.  No  Participant  shall have any rights as a
stockholder  with  respect  to any  shares of Common  Stock  covered  by a Stock
Appreciation  Right until the  Participant  becomes the holder of record of such
Common  Stock,  and  no  adjustments  shall  be  made  for  dividends  or  other
distributions  or other rights as to which there is a record date  preceding the
date such Participant becomes the holder of record of such Common Stock.

                                    SECTION X

                             RESTRICTED STOCK AWARDS

      10.1 Awards Granted by Committee. Coincident with or following designation
for participation in the 1995 Plan, a Participant may be granted one or more

<PAGE>

Restricted  Stock Awards  consisting  of shares of Common  Stock.  The number of
shares granted as a Restricted Stock Award shall be determined by the Committee.
The Committee may, in its discretion,  require the payment by the Participant of
cash in an amount  equal to the par value of the  Common  Stock  subject  to the
Restricted Stock Award as a condition  precedent to the issuance of Common Stock
to the Participant.

      10.2  Restrictions.  A  Participant's  right to retain a Restricted  Stock
Award  granted  to him or her  under  Section  10.1  shall  be  subject  to such
restrictions,  including but not limited to the Participant's  continuous status
as an Employee, Director or Consultant for a restriction period specified by the
Committee,  or the attainment of specified performance goals and objectives,  as
may be established  by the Committee  with respect to such award.  The Committee
may in its sole discretion  require  different  periods of employment,  director
service or consulting service or different performance goals and objectives with
respect to different  Participants,  to different  Restricted Stock Awards or to
separate,  designated  portions  of  the  Common  Stock  shares  constituting  a
Restricted  Stock Award.  Subject to the  provisions of Sections 11 and 14, if a
Participant's   continuous  status  as  an  Employee,   Director  or  Consultant
terminates prior to the end of such restriction period or the attainment of such
goals and objectives as may be specified by the Committee,  the Restricted Stock
Award shall be forfeited and all shares of Common Stock related thereto shall be
immediately returned to the Company.

      10.3  Privileges of a Stockholder;  Transferability.  A Participant  shall
have all voting,  dividend,  liquidation and other rights with respect to Common
Stock in accordance with its terms received by him or her as a Restricted  Stock
Award under this  Section 10 upon  becoming  the holder of record of such Common
Stock;  provided,  however,  that the Participant's right to sell, encumber,  or
otherwise transfer such Common Stock (and any other securities issued in respect
of such  shares of Common  Stock as a stock  dividend,  stock split or the like)
shall be subject to the limitations of Section 16.2 hereof.

      10.4 Enforcement of Restrictions. The Committee may in its sole discretion
require  one or more of the  following  methods of  enforcing  the  restrictions
referred to in Section 10.2 and 10.3:

      (a)   Placing  a  legend  on the  stock  certificates  referring  to the
restrictions;

      (b)  Requiring  the  Participant  to keep  the  stock  certificates,  duly
endorsed, in the custody of the Company while the restrictions remain in effect;

                                   SECTION XI

              EFFECT OF TERMINATION OF SERVICE ON STOCK OPTIONS,
             STOCK APPRECIATION RIGHTS AND RESTRICTED STOCK AWARDS

      11.1  Effect  of  Termination  of  Service  on  Stock  Options  and  Stock
Appreciation  Rights.  No  Stock  Option  or  Stock  Appreciation  Right  may be
exercised unless, at the time of such exercise,  the Participant is an Employee,
Director or Consultant, except as follows:

      (a) The Stock Option or Stock  Appreciation  Right may be exercised within
such period of time after  termination  of service as is  specified in the Stock
Option or Stock Appreciation Right agreement or instrument,  but (i) in no event
may such  post-termination  period extend beyond the original expiration date of
the Stock  Option or Stock  Appreciation  Right and (ii) only to the extent that
the  Participant  was  entitled  to exercise  it at the date of  termination  of
service.  In the  absence  of a  specified  time in the  Stock  Option  or Stock
Appreciation   Right  agreement  or  instrument,   the  Stock  Option  or  Stock
Appreciation Right shall remain exercisable for the applicable period and to the
extent specified in Section 11.5 below following the  Participant's  termination
of service as an Employee,  Director or Consultant.  In the case of an Incentive
Stock  Option,  such  period of time  shall not  exceed 90 days from the date of
termination of status as an Employee;  provided, however, that the agreement may
specify  a  longer  period,  in which  case  Stock  Option  shall  convert  to a
Non-Qualified Option on the 91st day following termination of employment;

      (b) If the  Participant  dies while  serving as an  Employee,  Director or
Consultant,  or within three months after the  Participant  ceases such service,
the Stock Option or Stock  Appreciation  Right may be exercised by the person to
whom it is  transferred by will or the laws of descent and  distribution  within
such period of time after  death as is  specified  in the Stock  Option or Stock
Appreciation Right agreement or instrument,  but in no event may such post-death
period extend beyond the original  expiration  date of the Stock Option or Stock
Appreciation  Right.  In the absence of a specified  time in the Stock Option or
Stock  Appreciation  Right  agreement or  instrument,  the Stock Option or Stock
Appreciation Right shall remain exercisable for the applicable period and to the
extent specified in Section 11.5 below; or

      (c) If the  Participant  becomes  disabled  (within the meaning of Section
22(e)(3) of the Internal Revenue Code) while serving as an Employee, Director or
Consultant, the Stock Option or Stock Appreciation Right may be exercised within
such period of time after  termination  of service as is  specified in the Stock
Option or Stock Appreciation Right agreement or instrument,  but in no event may
such  post-termination  period extend beyond the original expiration date of the
Stock Option or Stock Appreciation Right. In the absence of a specified time in

<PAGE>

the Stock Option or Stock Appreciation Right agreement or instrument,  the Stock
Option or Stock  Appreciation  Right shall remain exercisable for the applicable
period and to the extent specified in Section 11.5 below.

      11.2 Effect of Termination of Service on Restricted  Stock Awards.  In the
event  of  the  death  or  disability  (as  defined  in  Section  11.1(c))  of a
Participant,  all  period  of  service  and  other  restrictions  applicable  to
Restricted  Stock Awards then held by such  Participant  shall  lapse,  and such
awards  shall  become  fully  vested  and  nonforfeitable.  In  the  event  of a
Participant's  termination of service for any other reason, any Restricted Stock
Awards as to which the  employment  period or other  restrictions  have not been
satisfied shall be forfeited.

      11.3  Meaning of  Employment.  For all  purposes  of the 1995 Plan and any
Stock Option or Stock Appreciation  Right granted hereunder,  "employment" shall
be defined in accordance  with the provisions of Section 3401(c) of the Internal
Revenue Code and the regulations thereunder.

      11.4 Meaning of Continuous Status. Unless otherwise specified in the Stock
Option  or  Stock  Appreciation  Right  agreement  or  instrument,  so long as a
Participant is either an Employee or a Director or a Consultant, he or she shall
be considered to be in continuous status as an Employee, Director or Consultant,
even if the  person is  serving in one  capacity  when the award is granted  and
subsequently  changes to service in a different  capacity,  such as  terminating
employment but continuing to serve as a Consultant.

      11.5 Default Provisions for Termination of Service.  In the event that the
Stock Option or Stock  Appreciation Right agreement or instrument do not specify
the  post-termination  period of exercisability,  the following provisions shall
apply:

      (a) Subject to  11.5(f),  if such  termination  is due to the death of the
Participant, or the Participant dies within three months after such termination,
or if such termination occurs after the Participant becomes disabled (within the
meaning of Section  22(e)(3) of the Internal  Revenue Code), the Stock Option or
Stock Appreciation Right may be exercised by the Participant (or, in the case of
death,  by the person to whom it is  transferred  by will of the laws of descent
and   distribution):   (i)  for  all  Incentive  Stock  Option  grants,  or  for
Non-Qualified Stock Option grants or Stock Appreciation Right grants made before
May 22, 1997, or for  Non-Qualified  Stock Option  grants or Stock  Appreciation
Right grants made on or after May 22, 1997, if, at the time of the Participant's
termination, such Participant was not a Long-Term Employee, then within a period
of one year after the date of death (but in no event longer than the term of the
Stock Option or Stock Appreciation  Right); and (ii) for grants made on or after
May 22, 1997,  if the  Participant  was a Long-Term  Employee at the time of the
Participant's termination,  the Non-Qualified Stock Option or Stock Appreciation
Right  may be  exercised,  to the  extent  it is  vested  as of the  date of the
Participant's termination, for the entire remaining term of such Stock Option or
Stock Appreciation Right. <PAGE>

      (b) Subject to 11.5(f),  if such termination  occurs after the Participant
becomes disabled (within the meaning of Section 22(e)(3) of the Internal Revenue
Code), the Stock Option or Stock  Appreciation  Right may be exercised:  (i) for
all Incentive Stock Option grants,  or for  Non-Qualified  Stock Option or Stock
Appreciation  Right grants made before May 22, 1997, or for Non-Qualified  Stock
Option grants or Stock  Appreciation Right grants made on or after May 22, 1997,
if, at the time of the  Participant's  termination,  such  Participant was not a
Long-Term  Employee,  then  within a period  of one year  after the date of such
termination  (but in no event  longer than the term of the Stock Option or Stock
Appreciation  Right);  and (ii) for grants made on or after May 22, 1997, if the
Participant  is a Long-Term  Employee,  a  Non-Qualified  Stock  Option or Stock
Appreciation Right may be exercised to the extent it is vested as of the date of
the Participant's termination for the entire remaining term of such Stock Option
or Stock Appreciation Right.

      (c)  Subject to 11.5(f),  if such  termination  is due to a  Reduction  in
Force,  then,  for grants on or after May 22,  1997,  the Stock  Option or Stock
Appreciation  Right shall be  exercisable,  to the extent  vested at the time of
such termination, for a period of six months from the date of such termination.

      (d) Subject to 11.5(f), if the Participant Retires, then, for grants on or
after May 22,  1997,  the  Stock  Option or Stock  Appreciation  Right  shall be
exercisable,  to the extent vested at the time the Participant  Retires, for the
entire remaining term of such Stock Option or Stock Appreciation Right.

      (e) Subject to 11.5(f), if the Participant's  employment is terminated for
any reason other than those reasons  covered by  subsections  (a) through (d) of
this Section 11.5,  then the Stock Option or Stock  Appreciation  Right shall be
exercisable, to the extent vested at the time of such termination,  for a period
of ninety (90) days after the date of such termination.

      (f) Notwithstanding the provisions of Section 11.5(a) through (e) above:

            (i)  With   respect  to  all  grants  of  Stock   Options  or  Stock
      Appreciation  Rights  occurring on or after May 22,  1997,  no such grants
      shall be exercisable after the date of termination of employment if either
      the termination was for Cause,  or if the former  Employee,  Consultant or
      Director is then, in the sole judgment of the Company,  in material breach
      of any contractual,  statutory, fiduciary or other legal obligation to the
      Company.

                  (ii) In addition to the  provisions  of  paragraph  (i) above,
      unless  otherwise  provided  in the  Option  or Stock  Appreciation  Right
      agreement,   with  respect  to  all  grants  of  Stock  Options  or  Stock
      Appreciation Rights occurring on or after March 4, 1998 (or earlier date

<PAGE>

      if  agreed  to by the  Company  and the  participant):  (x) if at any time
      within  six months  after  termination  of the  optionee's  employment  or
      service,  the former  Employee,  Consultant  or  Director  is, in the sole
      judgment  of the  Company,  engaging  or has  engaged in any  activity  in
      competition  with any activity of the  Company,  or harmful or contrary to
      the  interests of the Company,  including,  but not limited to:  accepting
      employment with or serving as a consultant or advisor to any employer that
      is in competition  with the Company or acting against the interests of the
      Company, including employing or recruiting any Employee of the Company; or
      disclosing  or  misusing  any   confidential,   proprietary   or  material
      information  concerning the Company (such  information  includes,  without
      limitation,  information regarding the Company's operations, its products,
      product  designs,   business  plans,   strategic   plans,   marketing  and
      distribution plans and arrangements,  customers, and financial statements,
      budgets and forecasts);  or  participating in any hostile takeover attempt
      of the Company,  then (I) any Options or Stock  Appreciation  Rights still
      held by the optionee shall  immediately  cease to be exercisable and shall
      be canceled,  and (II) any shares issued upon exercise of Options or Stock
      Appreciation Rights after the date of termination of employment or service
      shall be sold back to the  Company  at the  exercise  price  paid for such
      shares,  and any cash received upon exercise of a Stock Appreciation Right
      after  termination  of  employment  or service  shall be  returned  to the
      Company; (y) if the Employee, Consultant or Director leaves the employment
      of the  Company  within six months of  exercising  Stock  Options or Stock
      Appreciation Rights for any reason except death, disability or retirement,
      then any gain represented by the fair market value on the date of exercise
      over the exercise price multiplied by the number of shares such individual
      purchased  ("option gain"),  without regard to any subsequent market price
      decrease or increase, shall be paid by such individual to the Company; and
      (z) shares  issued upon exercise of Options or Stock  Appreciation  Rights
      after termination of employment or service shall be non-transferable until
      six  months  after  such  termination  and  shall be held in escrow by the
      Company  until  such  time.  The  Compensation   Committee,  in  its  sole
      discretion, may, with respect to a particular Option or Stock Appreciation
      Right,  omit the provisions of this paragraph (ii) or release the optionee
      from  the  operation  of such  provisions  if the  Compensation  Committee
      determines that such action is in the best interests of the Company.

                                   SECTION XII

                      DIRECTOR STOCK AND STOCK EQUIVALENTS

      12.1 Director Stock and Stock Equivalents. Effective with the beginning of
the Company's fiscal year beginning December 28, 1996, each Outside Director may
receive  all or a portion of his or her annual  retainer  and any  meeting  fees
(which shall include any additional annual retainer or fees paid to a committee

<PAGE>

chair) in shares of Common Stock or, if elected by the Director, in Common Stock
Equivalents.  An election pursuant to this Section 12 must be made in writing on
or before  the first  day of the  beginning  of the  Outside  Director's  annual
retainer period and shall entitle the Outside  Director to a number of shares of
Common Stock or Common Stock  Equivalents  determined by dividing (a) the dollar
amount of the portion of the retainer  for the fiscal  period that is to be paid
in shares of Common  Stock or Common  Stock  Equivalents  by (b) the Fair Market
Value of one  share of  Common  Stock  as of the  last day of each  such  fiscal
period,  rounded up to the next full  number of shares.  In the event any person
becomes an Outside  Director  other than at the beginning of an annual  retainer
period, such person may elect, within thirty (30) days of the date on which such
person  becomes an Outside  Director,  to receive  his or her  retainer  and any
meeting fees in shares of Common Stock or Common Stock  Equivalents as described
above for the  balance of such annual  retainer  period in  accordance  with the
formula set forth in the preceding sentence.

      For purposes of this Section 12, an annual  retainer period shall begin on
the date of an Annual Meeting of the  Stockholders  of the Company and shall end
on the day immediately preceding the next following Annual Meeting.

      12.2 Stock Equivalents.  The number of Common Stock Equivalents determined
under Section 12.1 for each Outside  Director shall be credited to a bookkeeping
account  established in the name of that Director subject to the following terms
and conditions:

      (a) If the Company pays a cash  dividend  with respect to the Common Stock
 at  any  time  while  Common  Stock  Equivalents  are  credited  to an  Outside
 Director's  account,  there shall be credited to the Outside Director's account
 additional  Common Stock Equivalents equal to (i) the dollar amount of the cash
 dividend the Director  would have  received had he or she been the actual owner
 of the Common Stock to which the Common Stock  Equivalents then credited to the
 Director's  account relate,  divided by (ii) the Fair Market Value of one share
 of the Company's  Common Stock on the dividend  payment date.  The Company will
 pay the Director a cash payment in lieu of fractional stock  equivalents on the
 date of such dividend payment;

      (b) Upon the death or other termination of the Outside  Director's service
on the Board,  or, if authorized by the  Committee,  such other time or times as
specified by the Outside Director at the time of his or her annual  election(s),
the Company  shall  deliver to the Outside  Director  (or his or her  designated
beneficiary  or  estate) a number of shares of Common  Stock  equal to the whole
number of Common Stock  Equivalents  then  credited to the  Director's  account,
together  with a cash payment  equal to the Fair Market Value of any  fractional
Common Stock Equivalent; <PAGE>

      (c) The  Company's  obligation  with respect to Common  Stock  Equivalents
shall not be funded or secured in any  manner,  nor shall an Outside  Director's
right  to  receive  Common  Stock   equivalents  be  assigned  or  transferable,
voluntarily or involuntarily, except as expressly provided herein; and

      (d) An  Outside  Director  shall not be  entitled  to any  voting or other
stockholder  rights as a result of the credit of Common Stock Equivalents to the
Director's  account until certificates  representing  shares of Common Stock are
delivered  to the  Director  (or his or her  designated  beneficiary  or estate)
hereunder.

      12.3  Elections.  The  Committee  shall  determine  the  form  of  Outside
Director's  elections pursuant to this Section 12, which form shall evidence the
particular provisions,  terms, conditions,  rights and duties of the Company and
the Outside  Directors with respect to Common Stock and Common Stock Equivalents
paid with respect to the Director's annual retainer and any meeting fees.

                                  SECTION XIII

                                  MBO PAYMENTS

      13.1 Participant Election As to MBO Payment. At such time as the Committee
determines  that a  Participant  has or may become  eligible  for an MBO Payment
pursuant to the MBO Plan, the Committee may notify the Participant as to whether
or not the  Participant  will be required by the  Committee to, or will be given
the right to elect to,  accept all or a part of such MBO  Payment in the form of
shares of Common Stock or Common Stock Equivalents.  If the Committee grants the
Participant the right to elect whether to accept the MBO Payment in Common Stock
or Common Stock  Equivalents,  then the Participant shall have ten (10) business
days after the receipt of such notice from the Committee to make such  election.
The  Participant  shall notify the Committee with respect to his or her election
on such form as may be provided for this purpose by the Committee, setting forth
thereon  the  dollar  value of the  portion of the MBO  Payment  which he or she
desires to receive in shares of Common Stock or Common Stock  Equivalents.  If a
Participant  fails to make an election  pursuant to this Section with respect to
the mode of payment of an MBO Payment,  the entire MBO Payment  shall be made in
cash.

      13.2  Determination  of Number of  Shares.  The number of shares of Common
Stock or Common  Stock  Equivalents  that shall be issued or  credited as an MBO
Payment  shall be  determined by dividing the dollar value of the portion of the
MBO  Payment  that is to be paid in  shares  of  Common  Stock or  Common  Stock
Equivalents  (whether as elected above or as adjusted by the Committee  pursuant
to Section  13.3) by the Fair Market  Value of the Common  Stock on the date the
shares are issued or credited with respect to such Payment. No fractional shares
of Common Stock or Common Stock Equivalent shall be issued or credited as a part

<PAGE>

of an MBO  Payment  and the  value  of any  such  fractional  share  that  would
otherwise  be issued  pursuant to the  Participant's  election  shall be paid in
cash.

      13.3 Decision of Committee.  The Committee  shall have the sole discretion
to either  accept the  Participant's  election with respect to the payment of an
MBO  Payment,  in whole or in part,  in shares of Common  Stock or Common  Stock
Equivalents or to determine that a lesser  portion,  or none, of the MBO Payment
will be made in shares of Common  Stock or  Common  Stock  Equivalents,  and the
Committee's  determination  in this  regard  shall be final and  binding  on the
Participant.

                                   SECTION XIV

                         TENDER OFFERS AND ACQUISITIONS

      14.1 Tender Offers and  Acquisitions.  If any person or entity (other than
the Company or any person or entity that is  controlled  by the  Company)  shall
make a tender offer or exchange offer for all or any part of the Common Stock or
other  capital  shares of the Company and shall  purchase any part of the Common
Stock or other capital shares  tendered to it, and the Board opposes or does not
affirmatively recommend acceptance of such tender offer or exchange offer, then:

      (a) all Stock Options with respect to which no Stock  Appreciation  Rights
have  been  granted,   and  all  Stock  Options  with  respect  to  which  Stock
Appreciation  Rights have been issued (and all such related  Stock  Appreciation
Rights)  that  have  been  outstanding  for at least six  months,  shall  become
immediately  exercisable in full during the remaining  term thereof,  whether or
not the  Participants  to whom such options and rights have been granted  remain
Employees,  Directors or Consultants  of the Company;  provided,  however,  that
Stock  Appreciation  Rights shall remain subject to the  requirements of Section
9.2(a) with respect to the exercise thereof only within prescribed periods after
public release of Company financial information;

      (b) all restrictions  with respect to outstanding  Restricted Stock Awards
shall immediately lapse; and

      (c) all Common Stock Equivalents shall convert into shares of Common Stock
as of the date determined by the Committee.
<PAGE>

                                   SECTION XV

                           OTHER COMMON STOCK PROGRAMS

      15.1 Other Common Stock Programs. From time to time during the duration of
the 1995  Plan,  the  Board  may,  in its  sole  discretion,  adopt  one or more
incentive  compensation  arrangements  for  Eligible  Employees,   Directors  or
Consultants pursuant to which such Eligible Employees,  Directors or Consultants
may  acquire  shares of Common  Stock or Common  Stock  Equivalents,  whether by
purchase, outright grant or otherwise. Any such arrangements shall be subject to
the general provisions of the 1995 Plan and all shares of Common Stock or Common
Stock  Equivalents  issued or credited  pursuant to such  arrangements  shall be
issued under the 1995 Plan if so designated by the Committee.

                                   SECTION XVI

                             RIGHTS OF PARTICIPANTS

      16.1  Employment,   Directorship  or  Consulting   Relationship.   Nothing
contained in the 1995 Plan or in any Stock  Option,  Stock  Appreciation  Right,
Restricted  Stock Award or other Common Stock or Common Stock  Equivalent  award
granted  under the 1995 Plan shall  confer upon any  Participant  any right with
respect to the  continuation of his or her employment,  service as a director or
consulting  relationship  with the  Company or any  Affiliated  Corporation,  or
interfere  in  any  way  with  the  right  of  the  Company  or  any  Affiliated
Corporation,  subject to the terms of any separate agreement to the contrary, at
any time to terminate  such service or to increase or decrease the  compensation
of the  Participant  from the rate in  existence  at the time of the  grant of a
Stock Option,  Stock Appreciation Right,  Restricted Stock Award or other Common
Stock or Common Stock Equivalent award.  Whether an authorized leave of absence,
or absence in military or government  service,  shall constitute  termination of
service shall be determined by the Committee at the time.

      16.2 Nontransferability. Except as otherwise approved by the Committee and
set forth in the agreement between the Company and the Participant,  no right or
interest of any  Participant in a Stock Option,  a Stock  Appreciation  Right, a
Restricted  Stock  Award  prior  to the  completion  of the  restriction  period
applicable  thereto,  or other  Common Stock or Common  Stock  Equivalent  award
granted pursuant to the 1995 Plan shall be assignable or transferable during the
lifetime of the Participant,  either voluntarily or involuntarily,  or subjected
to any  lien,  directly  or  indirectly,  by  operation  of law,  or  otherwise,
including execution,  levy, garnishment,  attachment,  pledge or bankruptcy.  If
permitted  by  applicable  law  (including  Rule 16b-3,  as amended from time to
time),  the Committee  may (but need not) permit the transfer of Stock  Options,
Stock Appreciation Rights,  Restricted Stock Awards and/or other Common Stock or
Common Stock Equivalent awards either  generally,  to a limited class of persons
or  on  a  case-by-case  basis.  In  the  event  of  a  Participant's  death,  a
Participant's  rights and interest in Stock Options,  Stock Appreciation Rights,
Restricted Stock Awards and other Common Stock or Common Stock Equivalent awards

<PAGE>

shall  be  transferable  by  testamentary  will  or  the  laws  of  descent  and
distribution,  and  payment of any amounts due under the 1995 Plan shall be made
to, and exercise of any Stock Options or Stock  Appreciation  Rights may be made
by,  the  Participant's  legal  representatives,  heirs or  legatees.  If in the
opinion of the  Committee a person  entitled  to payments or to exercise  rights
with  respect to the 1995 Plan is  disabled  from  caring for his or her affairs
because of mental condition, physical condition, or age, payment due such person
may be made to, and such rights shall be exercised by, such  person's  guardian,
conservator or other legal personal representative upon furnishing the Committee
with evidence satisfactory to the Committee of such status.

                                  SECTION XVII

                              GENERAL RESTRICTIONS

      17.1  Investment  Representations.  The  Company may require any person to
whom a Stock Option,  Stock  Appreciation  Right,  Restricted  Stock Award,  MBO
Payment or other Common Stock or Common Stock Equivalent award is granted,  as a
condition  of  exercising  such Stock  Option or Stock  Appreciation  Right,  or
receiving such Restricted  Stock Award,  MBO Payment or other Common Stock award
or Common Stock  Equivalent  award, to give written  assurances in substance and
form  satisfactory to the Company and its counsel to the effect that such person
is acquiring the Common Stock subject to the Stock  Option,  Stock  Appreciation
Right,  Restricted  Stock  Award,  MBO Payment or Common  Stock or Common  Stock
Equivalent  award for his or her own  account  for  investment  and not with any
present  intention of selling or otherwise  distributing  the same,  and to such
other effects as the Company deems  necessary or  appropriate in order to comply
with federal and applicable state securities laws.

      17.2   Compliance  with   Securities   Laws.  Each  Stock  Option,   Stock
Appreciation  Right  and  Common  Stock  Equivalent  shall  be  subject  to  the
requirement that, if at any time counsel to the Company shall determine that the
listing,  registration  or  qualification  of the  shares  subject to such Stock
Option,  Stock Appreciation Right or Common Stock Equivalent upon any securities
exchange  or under any state or federal  law,  or the consent or approval of any
governmental  or  regulatory  body,  is  necessary  as a  condition  of,  or  in
connection  with,  the  issuance or purchase  of shares  thereunder,  such Stock
Option,  Stock Appreciation Right or Common Stock Equivalent may not be accepted
or   exercised  in  whole  or  in  part  unless  such   listing,   registration,
qualification,  consent or  approval  shall have been  effected  or  obtained on
conditions  acceptable  to the  Committee.  Nothing  herein  shall be  deemed to
require  the  Company to apply for or to obtain such  listing,  registration  or
qualification.

      17.3 Changes in Accounting Rules.  Notwithstanding  any other provision of
the 1995 Plan to the contrary, if, during the term of the 1995 Plan, any changes

<PAGE>

in the financial or tax  accounting  rules  applicable to Stock  Options,  Stock
Appreciation Rights, Restricted Stock Awards, MBO Payments or other Common Stock
or Common Stock Equivalent  awards shall occur that, in the sole judgment of the
Committee,  may have a material adverse effect on the reported earnings,  assets
or liabilities of the Company,  the Committee  shall have the right and power to
modify as necessary,  or cancel,  any then  outstanding  and  unexercised  Stock
Options or Stock  Appreciation  Rights,  any then  outstanding  Restricted Stock
