                                    FORM OF
                    LEASE AGREEMENT FOR ELECTRONIC BILLBOARD

This LEASE AGREEMENT FOR ELECTRONIC  BILLBOARD (the "Agreement") is entered into
by and between ELECTRONIC  BILLBOARD  TECHNOLOGY,  INC.  (hereinafter  "EBT"), a
Delaware  corporation  having its principal offices at 3006 Longhorn  Boulevard,
Suite 107, Austin, Texas 78758; and "ECKERD CORPORATION"  (hereinafter "ECKERD")
a   _____________________   corporation   having   its   principal   offices  at
_____________________________ (collectively the "parties" or Parties").

                                   BACKGROUND:

THIS  BACKGROUND  IS INCLUDED TO ASSIST IN  INTERPRETING  THIS  AGREEMENT AND TO
UNDERSTAND THE BASIS UPON WHICH CERTAIN TERMS AND CONDITIONS  HAVE BEEN INCLUDED
IN THIS CONTRACT. IT IS NOT INTENDED,  NOR SHOULD IT BE CONSTRUED,  TO SUPERSEDE
OR AMEND THE SPECIFICALLY, RECITED TERMS AND CONDITIONS OF THIS AGREEMENT.

EBT produces an Electronic Billboard. Eckerd is interested in testing the use of
the Electronic  Billboard at one of its pharmacy  locations with the possibility
of expanding the use of Electronic  Billboards  at other of its  locations.  The
purpose  of this  Agreement  is to  establish  the terms and  conditions  of the
initial site test.

                                    GENERAL:

1)   EBT, at its sole cost and expense, does hereby agree to erect an Electronic
     Billboard  (a  device  produced  by  EBT  for   electronically   displaying
     advertising  messages)  at  the  site  and in the  location  designated  on
     Schedule A of this Agreement.  The Electronic Billboard will be constructed
     according  to the  specifications  provided by Eckerd,  which are  attached
     hereto and marked  Schedule B. Eckerd does hereby agree to lease to EBT the
     space shown on Schedule A, and such  additional  space  around the location
     marked on Schedule A as is  reasonably  required for EBT to erect,  operate
     and maintain  the  Electronic  Billboard,  on the terms and  conditions  as
     hereafter set forth (herein, the "Lease").  The Lease specifically includes
     the right of EBT to sell  advertising  to third  parties on the  Electronic
     Billboard.  The third  parties may include  local,  regional  and  national
     advertisers.
2)   EBT, with the reasonable  assistance of Eckerd,  shall be  responsible  for
     obtaining all necessary permits and licenses to erect, operate and maintain
     the  Electronic  Billboard.  If, for any reason,  EBT is  prevented  by any
     governmental   authority  from  erecting  and   reasonably   operating  the
     Electronic  Billboard,  then this Agreement shall terminate and become null
     and void.
3)   The  Lease  shall be for a period  of one (1) year  from the date  that the
     Electronic  Billboard is installed  and  operational.  However,  Eckerd may
     terminate  the Lease at any time by giving EBT no less than 60 days written
     notice of its intent to terminate the Lease.  Upon the  termination  of the
     Lease, EBT shall, at its cost and expense,  remove the Electronic Billboard
     and  restore  the  location  to  the  condition  it  was  in  prior  to the
     installation of the Electronic Billboard, normal wear and tear excepted.
4)   As consideration for the Lease, EBT shall pay to Eckerd rental equal to ten
     (10%) percent of the  Advertising  Revenue  received from  operation of the
     Electronic Billboard. The aggregate collected gross cash proceeds generated
     from  all  advertising   displayed  on  the  Electronic  Billboard  ("Gross
     Revenue"),  shall be the basis of the  calculation  of rental to be paid to
     Eckerd.  Gross  Revenues  shall be reduced by the amount of all  applicable
     sales  taxes and tax  levies,  if any,  with  respect  thereto to arrive at
     Advertising  Revenue.  Rentals shall be paid monthly, on or before the 15th
     day of each month.
5)   EBT, at its sole cost and expense,  shall be responsible for the repair and
     maintenance  of the  Electronic  Billboard.  Eckerd,  at its sole  cost and
     expense,  shall be  responsible  for the cost of  electricity  to power the
     Electronic Billboard.
6)   EBT shall maintain all risk property  casualty  insurance on the Electronic
     Billboard  during the term of this Lease in an amount  equal to 100% of the
     replacement cost of the Electronic Billboard.
<PAGE>

7)   EBT shall maintain liability  insurance during the term of this Lease which
     includes  Eckerd as a named  insured  as  follows
     a)  Commercial  general  liability  insurance  in an  amount  not less than
         $1,000,000  per  occurrence  for bodily  injury or  property  damage or
         personal injury, $2,000,000 in the aggregate; and,
     b)  All such policies shall contain endorsements whereby the carrier agrees
         that its insurance is primary and not contributory with or in excess of
         any coverage which Eckerd may carry.
8)   The Parties  will  promptly  execute and deliver to each other such further
     documents  and take  such  further  action  as shall  be  required  to more
     effectively  carry out the intent and  purpose  of this  Agreement  and the
     Lease.
9)   All  notices,  demands,  or  consents  required  or  permitted  under  this
     Agreement shall be in writing and shall be delivered  personally or sent by
     certified or registered mail, return receipt requested,  to the appropriate
     party at the address set forth in the first  paragraph of this Agreement or
     at such  other  address  as shall be given by either  party to the other in
     writing.
10)  This  Agreement  and the  Lease  shall be deemed to be made in the state of
     Texas and in all respect shall be interpreted,  construed,  and governed by
     and in accordance with the laws of the state of Texas. Venue for any action
     arising under this  Agreement or the Lease shall be  exclusively in a court
     of competent jurisdiction,  state or federal, Austin, Travis County, Texas,
     to the extent permissible under applicable venue rules.
11)  The waiver by any party of any term or  provision of this  Agreement  shall
     not be deemed to constitute a continuing  waiver thereof nor of any further
     or additional rights such party may hold under this Agreement.

     ENTERED INTO EFFECTIVE THIS 21ST DAY OF JANUARY, 2000.

                                  October 2, 1998

     VIEWLOGIC SYSTEMS, INC., a Delaware corporation with a principal place
of business at 293 Boston Post Road West, Marlboro, Massachusetts 01752-4615
(hereinafter the "Borrower"), FLEET NATIONAL BANK, a national banking
association organized under the laws of the United States and having a head
office at One Federal Street, Boston, Massachusetts 02110, as agent,
(hereinafter sometimes the "Agent," as Agent for itself and each of the other
Lenders who now and/or hereafter become parties to this Agreement pursuant to
the terms of SECTION 9.11 hereof, sometimes "Fleet," and sometimes in its
capacity as a Lender "Lender"), and such Lenders, hereby agree as follows:

                                     ARTICLE 1.
                     DEFINITIONS AND ACCOUNTING AND OTHER TERMS

     SECTION 1.1.    CERTAIN DEFINED TERMS.  As used in this Agreement, the
following terms shall have the following meanings (such meanings to be
equally applicable to both the singular and plural forms of the terms
defined):

     "ADJUSTED LIBOR RATE" means, with respect to any Libor Loan to be made
by the Lenders for the Interest Period applicable to such Libor Loan, the
rate per annum (rounded upward, if necessary, to the nearest 1/32 of one
percent) as determined on the basis of the offered rates for deposits in
Dollars, for a period of time and for an amount comparable to such Libor
Loan which appears on the Telerate page 3750 as of 11:00 a.m. London time on
the day that is two Business Days preceding the first day of such Libor Loan;
provided, however, if the rate described above does not appear on the
Telerate System on any applicable Interest Adjustment Date, the Adjusted
Libor Rate shall be the rate (rounded upwards as described above, if
necessary) for deposits in Dollars for a period and for an amount comparable
to such Libor Loan on the Reuters Page "LIBO" (or such other page as may
replace the LIBO Page on that service for the purpose of displaying such
rates), as of 11:00 a.m. (London Time), on the day that is two Business Days
prior to the beginning of such Interest Period.

     If both the Telerate and Reuters system are unavailable, then the rate
for that date will be determined on the basis of the offered rates for
deposits in Dollars for a period of time and for an amount comparable to such
Libor Loan which are offered to each Reference Lender by four first-class
banks in the London interbank market at approximately 11:00 a.m. London time,
on the day that is two Business Days preceding the first day of such Libor
Loan as selected by the Lender.  The principal London office of each of the
four first-class London banks will be requested to provide a quotation of its
Dollar deposit offered rate.  If at least two such quotations are provided,
the rate for that date will be the arithmetic mean of the quotations.  If
fewer than two quotations are provided as requested, the rate for that date
will be determined on the basis of the rates quoted for loans in Dollars to
leading European banks for a period of time comparable to such Libor Loan
offered by major banks in New York City at approximately 11:00 a.m. New York
City time, on the day that its two Business Days preceding the first day of
such Libor Loan.  In the event that the Reference Lenders are unable to
obtain any such quotation as provided

<PAGE>

above, it will be deemed that the Adjusted Libor Rate pursuant to a Libor
Loan cannot be determined.

     In the event that the Board of Governors of the Federal Reserve System
shall impose a "Reserve Percentage" with respect to Libor deposits of any
Reference Lender then, to the extent that the rate determined in the
foregoing paragraph does not include a provision for such Reserve Percentage,
for any period during which such Reserve Percentage shall apply, the Adjusted
Libor Rate shall be equal to the amount determined above divided by an amount
equal to 1 minus the Reserve Percentage.  If any Reference Lender fails to
provide its offered quotation to the Agent, the Adjusted Libor Rate shall be
determined on the basis of the offered quotation of the other Reference
Lender.  The Adjusted Libor Rate shall be adjusted automatically on and as of
the effective date of any change in the Libor Rate Reserve Percentage.

     "ADVANCE" and "ADVANCES" means the funding by any Lender of all or a
portion of the Loans in accordance with this Agreement.

     "AFFILIATE" means singly and collectively, any Person (other than a
Subsidiary) which, directly or indirectly, is in control of, is controlled
by, or is under common control with, the Borrower.  For purposes of this
definition, a Person shall be deemed to be "controlled by" the Borrower if
the Borrower possesses, directly or indirectly, power either to (i) vote 10%
or more of the securities having ordinary voting power for the election of
directors of such Person or (ii) direct or cause the direction of the
management and policies of such Person whether by contract or otherwise, and
the legal representative, successor or assign of any such Person.

     "AGENT" means Fleet or any other Person which is at the time in question
serving as the agent under the terms of Article 8 hereof and the other
Financing Documents.

     "AGREEMENT" means this loan agreement, as the same may from time to time
be amended.

excluding 12 o'clock noon on any Business Day using Eastern Standard

delivers its financial statements to the Agent for the fiscal quarter ending
April 3, 1999 (the "INITIAL PERIOD"), (i) with respect to Libor Loans, two
percent (2%), (ii) with respect to Prime Rate Loans one-half of one percent
(1/2%), and thereafter, the applicable per annum percentage set forth below:

     I           Greater than 2:1                 1%                 2.75%

</TABLE>

Any change in the Applicable Margin required pursuant to the foregoing shall
become effective on the fifth Business Day after the Agent receives the
Borrower's financial statements for the Borrower's fiscal quarter or
year-end, as the case may be.  In the event that the financial statements
required to be delivered pursuant to SECTION 5.3.2 or 5.3.3 are not delivered
when due, are delivered thereafter and an interest rate adjustment is
required, such adjustment shall be retroactively effective to the date on
which the financial statements in question should have been delivered to the
Agent in accordance with SECTION 5.3.2 or 5.3.3, as the case may be, and (i)
the Borrower shall pay any amount owing by the Borrower as a result thereof
upon written demand from the Agent or (ii) if any amount is owing to the
Borrower as a result of such adjustment, such amount shall be credited
against interest accruing on the Loans then outstanding ratably among the
Lenders.  In the event that the Applicable Margin which is calculated based
on the Borrower's unaudited financial statements for the any fiscal quarter
of any fiscal year of the Borrower delivered pursuant to Section 5.3.3 is
different from the Applicable Margin which is calculated based on the
Borrower's audited financial statements delivered pursuant to Section 5.3.2
for such year, then the Applicable Margin shall be adjusted retroactively,
and (i) if any amount is owing to the Lenders as a result of such adjustment,
the Borrower shall pay such amount upon demand by the Agent to the Agent for
the ratable benefit of the Lenders, or (ii) if any amount is owing to the
Borrower as a result of such adjustment, such amount shall be credited
against interest accruing on the Loans then outstanding ratably among the
Lenders, PROVIDED THAT in the event of a dispute as to the appropriate fiscal
quarter as to which any adjustment should be allocated, the decision of the
independent accountants of the Borrower shall be made in accordance with GAAP
and shall

                                       3

<PAGE>

be binding upon the Agent, the Lenders and the Borrower absent manifest
error.  If the amount of any credit due to Borrower as a result of such
adjustment exceeds the aggregate amount of interest accruing on the Loans in
all remaining periods during which Loans are outstanding, the Lenders shall
reimburse Borrower for the amount of such credit which remains unapplied to
pay interest within ten (10) Business Days after all Loans have been paid in
full and the Commitments are terminated.  The Agent shall send the Borrower
written notification (each a "Notice of Interest Rate Change") of each change
in the Applicable Margin in accordance with the Agent's customary procedures
as in effect from time to time, but the failure to send such notice shall
have no effect on the effectiveness or applicability of the foregoing
provisions of this definition or Borrower's obligations with respect to
payment and calculation of interest on the Loans.

     Each Notice of Interest Rate Change shall be deemed correct and accepted
by the Borrower unless within thirty (30) days after the date of any such
Notice of Interest Rate Change, written notice to the contrary is received by
the Agent from the Borrower.  In the event that no interest rate adjustment
is made by the Agent in accordance with the foregoing, or no Notice of
Interest Rate Change is received by the Borrower, any claim for an interest
rate adjustment under this provision must be made by the Borrower by written
statement of the Borrower's claim providing in reasonable detail the
Borrower's calculations of the interest rate adjustments being requested
delivered to the Agent no later than the earlier of (i) with respect to
adjustments based on the Borrower's unaudited financial statements, the
earlier of (A) thirty (30) days after the date such statements are delivered
to the Agent, and (B) seventy-five (75) days after the last day of each
Borrower fiscal quarter, and (ii) with respect to adjustments based on the
Borrower's audited financial statements, (A) thirty (30) days after the date
such statements are delivered and (B) one hundred and twenty (120) days after
the last day of each Borrower fiscal year end.

     "AUTHORIZED REPRESENTATIVE" means such senior personnel of the Borrower
as shall be duly authorized and designated in writing by the Borrower to
execute documents, instruments and agreements on its behalf and to perform
the functions of Authorized Representative under any of the Financing
Documents.

borrowed, any Indebtedness evidenced by notes, bonds, debentures, guaranties
or similar obligations including without limitation the Loans and any
obligation to pay money under a conditional sale or other title retention
agreement, the net aggregate rentals payable under any Capitalized Lease
Obligation, any reimbursement obligation for any letter of credit and any
obligations in respect of banker's and other acceptances or similar
obligations.

                           AMOUNT AND TERMS OF THE LOANS

     SECTION 2.1.    THE LOANS.

          SECTION 2.1.0. THE REVOLVING CREDIT LOANS.  Each of the Lenders
severally agrees, subject to the terms and conditions of this Agreement, to
make Advances of Revolving Credit Loans to the Borrower from time to time
after receipt by the Agent from time to time before the Revolving Credit
Repayment Date of, and at the times provided for in, a Request and an
Interest Rate Election from the Borrower in accordance with this Agreement,
during the period commencing on the Closing Date and ending on the Business
Day immediately preceding the Revolving Credit Repayment Date, in an
aggregate principal amount at any one time outstanding not to exceed such
Lender's Pro Rata Share of the Revolving Credit Loan Commitment less such
Lender's Pro Rata Share of the aggregate outstanding stated amount of any
Letters of Credit or Letter of Credit Agreements and any unreimbursed amounts
drawn thereunder.  The outstanding principal balance of the Revolving Credit
Loans shall be repaid on the Revolving Credit Repayment Date.

     Promptly after receipt of a Request and Interest Rate Election, Agent
shall notify each Lender by telephone, telex or telecopy of the proposed
borrowing. Subject to the immediately preceding paragraph, each Lender agrees
that after its receipt of notification from Agent of Agent's receipt of a
Request and Interest Rate Election, such Lender shall send its Pro Rata Share
(or such portion thereof as may be necessary to provide Agent with such Pro
Rata Share in Dollars and in immediately available funds, without
consideration or use of any contra accounts of any Lender) of the requested
Loan by wire transfer to Agent so that Agent receives such Pro Rata Share in
Dollars and in immediately available funds not later than 12:00 P.M. (Boston,
Massachusetts time) on the first day of the Interest Period for any such
requested Libor Loan and on the Business Day for such Advance set forth in
Borrower's Request for any such requested

                                       17

<PAGE>

Prime Rate Loan, and Agent shall advance funds to the Borrower by depositing
such funds in Borrower's account with the Agent upon Agent's receipt of such
Pro Rata Shares in the amount of the Pro Rata Shares of such Loan in Agent's
possession.  Unless Agent shall have been notified by any Lender (which
notice may be telephonic if confirmed promptly in writing) prior to the
first day of the Interest Period in respect of any Loan which such Lender is
obligated to make under this Agreement, that such Lender does not intend to
make available to Agent such Lender's Pro Rata Share of such Loan on such
date, Agent may assume that such Lender has made such amount available to
Agent on such date and Agent in its sole discretion may, but shall not be
obligated to, make available to the Borrower a corresponding amount on such
date.  If such corresponding amount is not in fact made available to Agent by
such Lender, Agent shall be entitled to recover such corresponding amount
from such Lender promptly upon demand by Agent together with interest
thereon, for each day from such date until the date such amount is paid to
Agent, at the Federal Funds Rate for three (3) Business Days and thereafter
at the interest rate on the Loan in question. If such Lender does not pay
such corresponding amount forthwith upon Agent's demand therefor, Agent shall
promptly notify the Borrower and the Borrower shall promptly pay such
corresponding amount to Agent.  Nothing contained in this Section shall be
deemed to relieve any Lender from its obligation to fulfill its obligations
hereunder or to prejudice any rights which the Borrower may have against any
Lender as a result of any default by such Lender hereunder.

     Throughout the term of the Revolving Credit Loans, the Revolving Credit
Loan Commitment may, in Fleet's discretion, be made available to the Borrower
prior to the Revolving Credit Repayment Date by issuance of Letters of Credit
having an expiration date prior to the earlier to occur of (a) the first
anniversary date of the date of issuance of any such Letter of Credit or (b)
three (3) Business Days prior to the Revolving Credit Repayment Date,
reasonably promptly after submission by the Borrower to the Agent of a Letter
of Credit Agreement, duly completed and executed by the Borrower and
otherwise in form and substance satisfactory to Fleet.  The Borrower shall
pay upon demand by the Agent such usual and customary fees and costs as Fleet
may from time to time establish for issuance, transfer, amendment and
negotiation of each Letter of Credit and shall pay to the Agent for Fleet's
account upon issuance of any Letter of Credit an annual Letter of Credit fee
in an amount equal to an amount determined by Fleet based on Fleet's usual
and customary fees charged for Letters of Credit similar to such Letter of
Credit.  In the event that the Borrower shall fail to reimburse Fleet under
any Letter of Credit or Letter of Credit Agreement, and any outstanding
Indebtedness of the Borrower relating thereto, Fleet shall promptly notify
the Agent, and the Agent shall, in turn, promptly notify each Lender of the
unreimbursed amount together with accrued interest thereon, and each Lender
agrees to purchase, and it shall be deemed to have purchased, a participation
in such Letter of Credit or Letter of Credit Agreement and such indebtedness
in an amount equal to its Pro Rata Share of the unpaid amount together with
unpaid interest thereon.  Upon one (1) Business Day's notice from the Agent,
each Lender shall deliver to the Agent an amount equal to its respective
participation in same day funds, at the place and on the date and by the time
notified by the Agent.  The obligation of each Lender to deliver to the Agent
an amount equal to its respective participation pursuant to the foregoing
sentence shall be absolute and unconditional and such remittance shall be
made notwithstanding the occurrence or continuation of an Event of Default or
the failure to satisfy any condition set forth in Article III of this
Agreement.

          SECTION 2.1.1. TERM LOANS.  Each of the Lenders severally agrees,
subject to the terms and conditions of this Agreement, to make a Term Loan to
the Borrower in the amount of its respective Pro Rata Share of $18,000,000.
Borrower shall pay on the last day of each fiscal quarter commencing January
2, 1999 the amount set forth below as the quarterly payment amount for the
fiscal year in question:

</TABLE>

     SECTION 2.2.    INTEREST AND FEES ON THE LOANS.

          SECTION 2.2.1. INTEREST; DEFAULT RATE OF INTEREST; SUSPENSION OF
LIBOR LOANS; ETC.  Interest shall accrue on the Loans at Effective Prime or
the Libor Rate for each of the Loans' Interest Periods in accordance with the
Borrower's Interest Rate Elections for the Loans subject to and in accordance
with the terms and conditions of this Agreement and the Note(s); provided
that if a Default or an Event of Default exists and is continuing, no
Interest Rate Election electing the Libor Rate shall be effective and all
Loans shall bear interest, payable on demand, at Effective Prime PLUS, so
long as an Event of Default exists and is continuing, two percent (2%) above
the Applicable Margin (the "DEFAULT RATE"); all of the foregoing being
applicable until such Default or Event of Default is cured or waived and, as
to availability of Libor Loans, an Interest Rate Election electing the Libor
Rate for such Loan or portion thereof which is effective in accordance with
this Agreement is submitted to the Agent; and provided further that the
Borrower shall submit Interest Rate Elections so that on any date on which
under SECTION 2.1.1 a regularly scheduled payment of principal of the Term
Loans is to be made, at least the amount of the Term Loans to be so repaid is
bearing interest at Effective Prime and/or such payment date is an Interest
Adjustment Date for outstanding Libor Loans in such amount of the Term Loans.
The Borrower shall pay such interest to the Agent for the pro rata account
of each Lender in arrears on the Loans (including without limitation Libor
Loans) outstanding from time to time after the Closing Date, such payments to
be made, with respect to Libor Loans with Interest Periods of three months or
less on each Interest Adjustment Date for such Loans, and with respect to
Libor Loans with Interest Periods of more than three months and with respect
to Prime Rate Loans, quarterly on the last Business Day of each calendar
quarter of each year.  In the event no Interest Rate Election has been made
by the Borrower with respect to any Loan or Advance (or an Interest Rate
Election shall have expired without an effective substitute Interest Rate
Election), Effective Prime shall be the rate applicable to such Loan or
Advance.  All provisions of each Note and any other agreements between the
Borrower and the Lenders are expressly subject to the condition that in no
event, whether by reason of acceleration of maturity of the Indebtedness
evidenced by any Note or otherwise, shall the amount paid or agreed to be
paid to the Lenders which is deemed interest under applicable law exceed the
maximum permitted rate of interest under applicable law (the "MAXIMUM
PERMITTED RATE"), which shall mean the law in effect on the date of this
Agreement, except that if there is a change in such law which results in a
higher Maximum Permitted Rate, then each Note shall be governed by such

                                       19

<PAGE>

amended law from and after its effective date. In the event that fulfillment
of any provision of any Note, or this Agreement or any document, instrument
or agreement providing security for any Note results in the rate of interest
charged under any Note being in excess of the Maximum Permitted Rate, the
obligation to be fulfilled shall automatically be reduced to eliminate such
excess.  If, notwithstanding the foregoing, any Lender receives an amount
which under applicable law would cause the interest rate under any Note to
exceed the Maximum Permitted Rate, the portion thereof which would be
excessive shall automatically be deemed a prepayment of and be applied to the
unpaid principal balance of such Note to the extent of then outstanding Prime
Rate Loans and not a payment of interest and to the extent said excessive
portion exceeds the outstanding principal amount of Prime Rate Loans, said
excessive portion shall be repaid to the Borrower.

          SECTION 2.2.2. FEES.  On the Closing Date the Borrower shall pay
the Facility Fee to the Agent for the account of Fleet.  In addition, on the
last Business Day of each March, June, September and December commencing
December 31, 1998 and continuing through the earlier of (i) the Revolving
Credit Repayment Date and (ii) the date that all amounts owed hereunder have
been paid and all Commitments to make Revolving Credit Loans have terminated,
the Borrower shall pay to the Agent for the pro rata account of each Lender,
a fee (the "Unused Fee") in an amount equal to .50% per annum of the amount,
if any, by which the average actual daily amount of the Revolving Credit Loan
Commitment for the quarterly period just ended (or in the case of the first
such payment, the period from the Closing Date to the date such payment is
due) exceeds the sum of the average of the actual daily outstanding principal
balances of the Revolving Credit Loans PLUS the average of the actual daily
aggregate amount of the outstanding stated amount of any Letter of Credit or
Letter of Credit Agreement, and any unreimbursed amounts thereunder.

          SECTION 2.2.3. INCREASED COSTS - CAPITAL.  If, after the date
hereof, any Lender shall have reasonably determined that the adoption after
the date hereof of any applicable law, governmental rule, regulation or order
regarding capital adequacy of banks or bank holding companies, or any change
therein, or any change 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 holding company with any policy, guideline, directive or
request regarding capital adequacy (whether or not having the force of law
and whether or not failure to comply therewith would be unlawful) of any such
authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on the capital of such Lender or such Lender's
holding company as a consequence of the obligations hereunder of such Lender
to a level below that which such Lender could have achieved but for such
adoption, change or compliance (taking into consideration the policies of
such Lender or such Lender's holding company with respect to capital adequacy
immediately before such adoption, change or compliance and assuming that the
capital of such Lender or such Lender's holding company was fully utilized
prior to such adoption, change or compliance) by an amount reasonably deemed
by such Lender to be material, then such Lender shall notify the Agent and
the Borrower thereof and the Borrower shall pay to the Agent for the account
of such Lender from time to time as specified by such Lender such additional
amounts as shall be sufficient to compensate such Lender for such reduced
return, each such payment to be made by the Borrower within ten (10) Business
Days after each demand by such Lender;

                                       20

<PAGE>

provided that the Borrower shall have no liability to pay such costs accruing
from and after the 60th day prior to the date of each such demand.  A
certificate in reasonable detail of one of the officers of such Lender
describing the event giving rise to such reduction and setting forth the
amount to be paid to such Lender hereunder and a computation of such amount
shall accompany any such demand and shall, in the absence of manifest error,
be presumptively correct.  In determining such amount, such Lender shall act
reasonably and will use any reasonable averaging and attribution methods.  If
the Borrower shall, as a result of the requirements of this SECTION 2.2.3
above, be required to pay any Lender the additional costs referred to above
and the Borrower, in its sole discretion, shall deem such additional amounts
to be material, the Borrower shall have the right to substitute another bank
satisfactory to the Agent for such Lender which has certified the additional
costs to the Borrower, and the Agent shall use reasonable efforts at no cost
to the Agent to assist the Borrower to locate such substitute bank.  Any such
substitution shall take place in accordance with SECTION 9.11 and shall
otherwise be on terms and conditions reasonably satisfactory to the Agent,
and until such time as such substitution shall be consummated, the Borrower
shall continue to pay such additional costs.  Upon any such substitution, the
Borrower shall pay or cause to be paid to the Lender that is being replaced,
all principal, interest (to the date of such substitution) and other amounts
owing hereunder to such Lender and such Lender will be released from
liability hereunder.

     SECTION 2.3.    NOTATIONS.  At the time of (i) the making of each
Advance evidenced by any Note, (ii) each change in the interest rate under
any Note effected as a result of an Interest Rate Election; and (iii) each
payment or prepayment of any Note, each Lender may enter upon its records an
appropriate notation evidencing (a) such Lender's Pro Rata Share of the Loans
and (b) the interest rate and Interest Adjustment Date applicable thereto or
(c) such payment or prepayment (voluntary or involuntary) of principal and
(d) in the case of payments or prepayments (voluntary or involuntary) of
principal, the portion of the applicable Loan which was paid or prepaid.  No
failure to make any such notation shall affect the Borrower's unconditional
obligations to repay the Loans and all interest, fees and other sums due in
connection with this Agreement and/or any Note in full, nor shall any such
failure, standing alone, constitute grounds for disproving a payment of
principal by the Borrower. However, in the absence of manifest error, such
notations and each Lender's records containing such notations shall
constitute presumptive evidence of the facts stated therein, including,
without limitation, the outstanding amount of such Lender's Pro Rata Share of
the Loans and all amounts due and owing to such Lender at any time.  Any such
notations and such Lender's records containing such notations may be
introduced in evidence in any judicial or administrative proceeding relating
to this Agreement, the Loans or any Note.

     SECTION 2.4.    COMPUTATION OF INTEREST.  Interest due under this
Agreement and any Note shall be computed on the basis of a year of 360 days
for the actual number of days elapsed.

     SECTION 2.5.    TIME OF PAYMENTS AND PREPAYMENTS IN IMMEDIATELY
                     AVAILABLE FUNDS.

          SECTION 2.5.1. TIME.  All payments and prepayments of principal,
fees, interest and any other amounts owed from time to time under this
Agreement and/or under each Note shall be made to the Agent for the pro rata
account of each Lender at the address referred to in SECTION 9.6 in Dollars
and in immediately available funds prior to 12:00 o'clock P.M. on the

                                       21

<PAGE>

Business Day that such payment is due, provided that the Borrower hereby
authorizes and instructs the Agent to charge against the Borrower's accounts
with the Agent on each date on which a payment is due hereunder and/or under
any Note and on any subsequent date if and to the extent any such payment is
not made when due an amount up to the principal, interest and fees due and
payable to the Lenders, the Agent or any Lender hereunder and/or under any
Note and such charge shall be deemed payment hereunder and under the Note(s)
in question to the extent that immediately available funds are then in such
accounts.  The Agent shall use reasonable efforts in accordance with the
Agent's customary procedures to give subsequent notice of any such charge to
the Borrower, but the failure to give such notice shall not affect the
validity of any such charge.  To the extent that immediately available funds
are then in such accounts, the failure of the Agent to charge any such
account or the failure of the Agent to charge any such account prior to 12
o'clock P.M. shall not be basis for an Event of Default under SECTION 6.1.1
and any amount due on the Loans on such date shall be deemed paid; provided
that the Agent shall have the right to charge any such account on any
subsequent date for such unpaid payment and an Event of Default shall exist
if sufficient immediately available funds are not in such accounts on the
date the Agent so charges such account after the expiration of any applicable
cure period.  In the event of any charge against the Borrower's accounts by
the Agent pursuant to the immediately preceding sentence, the Agent shall use
reasonable efforts to provide notice to the Borrower of such charge in
accordance with the Agent's customary procedures, but the failure to provide
such notice shall not in any way be a basis for any liability of the Agent
nor shall such failure adversely affect the validity and effectiveness of any
such action by the Agent. Any such payment or prepayment which is received by
the Agent in Dollars and in immediately available funds after 12 o'clock P.M.
on a Business Day shall be deemed received for all purposes of this Agreement
on the next succeeding Business Day unless the failure by Agent to receive
such funds prior to 12 o'clock P.M. is due to Agent's failure to charge the
account of Borrower prior to 12 o'clock P.M., except that solely for the
purpose of determining whether a Default or Event of Default has occurred
under SECTION 6.1.1, any such payment or prepayment, if received by the Agent
prior to the close of the Agent's business on a Business Day, shall be
deemed received on such Business Day.  All payments of principal, interest,
fees and any other amounts which are owing to any or all of the Lenders or
the Agent hereunder and/or under any of the Notes that are received by the
Agent in immediately available Dollars prior to 12:00 o'clock P.M. on any
Business Day shall, to the extent owing to the Lenders other than the Agent,
be sent by wire transfer by the Agent to any such other Lenders (in each
case, without deduction for any claim, defense or offset of any type) before
3:00 o'clock P.M. on the same Business Day.  Each such wire transfer shall be
addressed to each Lender in accordance with the wire instructions set forth
in EXHIBIT 1.9 hereto.  The amount of each payment wired by the Agent to each
such Lender shall be such amount as shall be necessary to provide such Lender
with its Pro Rata Share of such payment (without consideration or use of any
contra accounts of any Lender), or with such other amount as may be owing to
such Lender in accordance with this Agreement (in each case, without
deduction for any claim, defense or offset of any type).  Each such wire
transfer shall be sent by the Agent only after the Agent has received
immediately available Dollars from or on behalf of the Borrower and each such
wire transfer shall provide each Lender receiving same with immediately
available Dollars on receipt by such Lender.  Any such payments of
immediately available Dollars received by the Agent after 12:00 o'clock P.M.
and before 3:00 o'clock P.M. on any Business Day shall be forwarded in the
same manner by the Agent to such Lender(s) as soon as practicable on said
Business Day, and if any such payments of immediately

                                       22

<PAGE>

available Dollars are received by the Agent after 3:00 o'clock P.M. on a
Business Day, the Agent shall so forward same to such Lender(s) before 10:00
o'clock A.M. on the immediately succeeding Business Day.

          SECTION 2.5.2. SETOFF, ETC.  Regardless of the adequacy of any
collateral for any of the Obligations, upon the occurrence and during the
continuance of any Event of Default, each Lender is hereby authorized at any
time and from time to time, without notice to the Borrower (any such notice
being expressly waived by the Borrower), to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any
time held and any other Indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower against any and all of the
Obligations due and owing by the Borrower.  Each such Lender agrees to
promptly notify the Borrower and the Agent after any such setoff and
application; provided that the failure to give such notice shall not affect
the validity of such setoff and application.  Promptly following any notice
of setoff received by the Agent from a Lender pursuant to the foregoing, the
Agent shall notify each other Lender thereof.  The rights of each Lender
under this SECTION 2.5.2 are in addition to all other rights and remedies
(including, without limitation, other rights of setoff) which such Lender may
have and are subject to SECTION 9.12.

          SECTION 2.5.3. UNCONDITIONAL OBLIGATIONS AND NO DEDUCTIONS. The
Borrower's obligation to make all payments provided for in this Agreement and
the other Financing Documents when due shall be unconditional.  Each such
payment shall be made when due without deduction for any claim, defense or
offset of any type, including without limitation any withholdings and other
deductions on account of income or other taxes and regardless of whether any
claims, defenses or offsets of any type exist.

               SECTION 2.5.3.2.  (a)  Any and all payments by the Borrower to
or for the account of any Lender or the Agent hereunder or under any other
Financing Document shall be made free and clear of and without deduction for
any and all present or future taxes, duties, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding,
in the case of each Lender and the Agent, taxes imposed on its income, and
franchise taxes imposed on it, by the jurisdiction under the laws of which
such Lender (or its applicable lending office) or the Agent (as the case may
be) is organized or any political subdivision thereof, (all such non-excluded
taxes, duties, levies, imposts, deductions, charges, withholdings, and
liabilities being hereinafter referred to as "Taxes").  If the Borrower shall
be required by law to deduct any Taxes from or in respect of any sum payable
under this Agreement or any other Financing Document to any Lender or the
Agent,(i) the sum payable shall be increased as necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this SECTION 2.5.3.2) such Lender or the Agent receives an
amount equal to the sum it would have received had no such deductions been
made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall
pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law, and (iv) the Borrower shall
furnish to the Agent, at its address referred to in SECTION 9.6 hereof, the
original or a certified copy of a receipt evidencing payment thereof.

                                       23

<PAGE>

     (b)  In addition, the Borrower agrees to pay any and all present or
future stamp or documentary taxes and any other excise or property taxes or
charges or similar levies which arise from any payment made under this
Agreement or any other Financing Document or from the execution or delivery
of, or otherwise with respect to, this Agreement or any other Loan Document
(hereinafter referred to as "Other Taxes").

     (c)  The Borrower agrees to indemnify each Lender and the Agent for the
full amount of Taxes and Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts
payable under this SECTION 2.5.3.2) paid by such Lender or the Agent (as the
case may be) and any liability (including penalties, interest, and expenses)
arising therefrom or with respect thereto.

     (d)  Each Lender organized under the laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Lender listed on the signature pages hereof and
on or prior to the date on which it becomes a Lender in the case of each
other Lender, and from time to time thereafter if requested in writing by the
Borrower or the Agent (but only so long as such Lender remains lawfully able
to do so), shall provide the Borrower and the Agent with (i) a properly
completed Internal Revenue Service Form 1001 or 4224, as appropriate, or any
successor form prescribed by the Internal Revenue Service, certifying that
such Lender is entitled to benefits under an income tax treaty to which the
United States is a party which reduces the rate of withholding tax on
payments of interest or certifying that the income receivable pursuant to
this Agreement is effectively connected with the conduct of a trade or
business in the United States, (ii) a properly completed Internal Revenue
Service Form W-8 or W-9, as appropriate, or any successor form prescribed by
the Internal Revenue Service, certifying that such Lender is exempt from
United States backup withholding, and (iii) any other form or certificate
required by any taxing authority (including any certificate required by
Sections 871(h) and 881(c) of the Internal Revenue Code), certifying that
such Lender is entitled to an exemption from or a reduced rate of tax on
payments pursuant to this Agreement or any of the other Financing Documents.

     (e)  For any period with respect to which a Lender has failed to provide
the Borrower and the Agent with the appropriate form pursuant to Section
2.5.3.2(d) hereof (unless such failure is due to a change in treaty, law, or
regulation occurring subsequent to the date on which a form originally was
required to be provided), such Lender shall not be entitled to
indemnification under SECTION 2.5.3.2(a) OR 2.5.3.2(b) hereof with respect to
Taxes imposed by the United States; provided, however, that should a Lender,
which is otherwise exempt from or subject to a reduced rate of withholding
tax, become subject to Taxes because of its failure to deliver a form
required hereunder, the Borrower shall take such steps as such Lender shall
reasonably request and at such Lender's cost to assist such Lender to recover
such Taxes.

     (f)  If the Borrower is required to pay additional amounts to or for the
account of any Lender pursuant to this Section 2.5.3.2, then such Lender will
agree to use reasonable efforts to change the jurisdiction of its applicable
lending office so as to eliminate or reduce any such additional payment which
may thereafter accrue if such change, in the judgment of such Lender, is not
otherwise disadvantageous to such Lender.  Alternatively, in the event of
such an additional cost, the Borrower shall have the right to substitute
another bank satisfactory to the

                                       24

<PAGE>

Agent, and the Agent and such Lender shall use reasonable efforts at no cost
to the Agent and such Lender to assist the Borrower to locate and effect the
substitution in favor of such substitute bank.  Any such substitution shall
take place in accordance with SECTION 9.11 and shall otherwise be on terms
and conditions reasonably satisfactory to the Agent, and until such time as
such substitution shall be consummated, the Borrower shall continue to pay
such additional costs.  Upon any such substitution, the Borrower shall pay or
cause to be paid to the Lender that is being replaced, all principal,
interest (to the date of such substitution) and other amounts owing hereunder
to such Lender and such Lender will be released from liability hereunder.

     (g)  Within thirty (30) days after the date of any payment of Taxes, the
Borrower shall furnish to the Agent the original or a certified copy of a
receipt evidencing such payment.

     (h)  Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained
in this SECTION 2.5.3.2 shall survive until the first anniversary of the
Repayment Date.

     (i)  If the Borrower makes any additional payment to any Lender pursuant
to this SECTION 2.5.3.2 in respect of any Taxes, and such Lender determines
that it has received (i) a refund of such Taxes, or (ii) a credit against,
relief or remission for, or a reduction in the amount of, any tax or other
governmental charge as a result of any deduction or credit for any Taxes with
respect to which it has received payments under this SECTION 2.5.3.2, such
Lender shall, to the extent that it can do so without prejudice to the
retention of such refund, credit, relief, remission or reduction, pay to the
Borrower such amount as shall be reasonably determined by such Lender to be
solely attributable to the deduction or withholding of such Taxes.  If such
Lender later determines that it was not entitled to such refund, credit,
relief, remission or reduction to the full extent of any payment made
pursuant to the first sentence of this SECTION 2.5.3.2(i), the Borrower shall
upon demand of such Lender promptly repay the amount of such overpayment.
Nothing in this SECTION 2.5.3.2(i) shall be construed as requiring such
Lender to conduct its business or to arrange or alter in any respect its tax
or financial affairs so that it is entitled to receive such a refund, credit
or reduction or as allowing any Person to inspect any records, including tax
returns, of such Lender.

     SECTION 2.6.    PREPAYMENT AND CERTAIN PAYMENTS.

          SECTION 2.6.1. MANDATORY PAYMENTS.

               SECTION 2.6.1.1.  In addition to each other principal payment
required hereunder, the outstanding principal balances of the Term Loans
shall be repaid on the Term Loan Repayment Date and the outstanding principal
balances of the Revolving Credit Loans shall be repaid on the Revolving
Credit Repayment Date.

               SECTION 2.6.1.2.  On or before the 90th day after the end of
each fiscal year of the Borrower commencing with the fiscal year ending
September 30, 1999 if at the end of any such fiscal year the Leverage Ratio
is at any time greater than 2.0:1, the Borrower shall prepay to

                                       25

<PAGE>

the Agent for the accounts of the Lenders in accordance with their Pro Rata
Shares an amount of the outstanding principal balances of the Term Loans
equal to (i) fifty percent (50%) of the amount, if any, of Excess Cash Flow
for such fiscal year.  Such prepayments shall be in addition to any and all
other mandatory and voluntary prepayments required or permitted hereunder and
shall be applied to the principal installments of the Term Loans in the
inverse order of their maturities.

               SECTION 2.6.1.3.  In the event that the Borrower or any
Subsidiary is entitled to receive, collectively, proceeds from any casualty
insurance policies maintained by any of them on account of any interest of
the Borrower and/or any Subsidiary in any property, which proceeds are in an
amount in excess of $250,000 with respect to any occurrence or related
series of occurrences in any 12-month period, such proceeds shall be received
by the Agent and, to the extent that such proceeds result from a casualty to
property of the Borrower and/or any Subsidiary, so long as no Default or
Event of Default exists and is continuing and the Borrower elects to repair,
replace or restore such property, such proceeds shall be released to the
Borrower subject to reasonable procedures and conditions established by the
Agent to the extent necessary to so repair, replace or restore such property
within 3 months (or as soon as reasonably practicable if such restoration,
replacement or repair is not susceptible to being completed within 3 months)
from the date of receipt of such proceeds by the Agent and to the extent such
proceeds are not so used or do not result from such a casualty, the Borrower
shall make a prepayment of the Term Loans for the accounts of the Lenders in
accordance with their Pro Rata Shares upon written notice from the Agent
given within ten (10) Business Days following the determination that a
prepayment is due hereunder.  All such payments shall be applied to the
principal installments of the Term Loans in the inverse order of their
maturities.

               SECTION 2.6.1.4.  In the event that the Borrower and/or any
Subsidiary sells, assigns or otherwise transfers title to any assets
(tangible or intangible) other than in the ordinary course of its business
for aggregate net cash proceeds in excess of $100,000 in any fiscal year or
in excess of $500,000 in the aggregate since the Closing Date, the Borrower
and/or such Subsidiary shall remit 100% of the net cash proceeds of any sale,
assignment or other transfer which are in excess of such amounts to the Agent
for the accounts of the Lenders in accordance with their Pro Rata Shares to
be applied to the principal installments of the Term Loans in the inverse
order of their maturities within 90 days of the date of Borrower's or any
Subsidiary's receipt of such net cash proceeds; provided, however, that
Borrower may sell any asset (tangible or intangible) which is obsolete,
worn-out or no longer used or useful, or to be used, in Borrower's business
and Borrower may use the proceeds of such sale to purchase other assets
(tangible or intangible) which are, or will be, useful or necessary in the
operation of Borrower's business and if, and to the extent, so used, the
Borrower will not be required to make a prepayment hereunder.

               SECTION 2.6.1.5.  In the event that the Borrower and/or any
Subsidiary files a Form S-1 or any other form of registration statement then
available for registration with the Securities and Exchange Commission (other
than an offering on Form S-8 in respect of employee stock options) or
otherwise conducts an Initial Public Offering of any class of the Borrower's
or any Subsidiary's securities, the Borrower and/or such Subsidiary upon
receipt of the net aggregate cash consideration from the sale of any such
registered securities shall prepay to the Agent for the accounts of the
Lenders in accordance with their Pro Rata Shares the lesser of (i)

                                       26

<PAGE>

the net proceeds of such offering and (ii) the amount necessary to reduce the
total of the outstanding principal balance of the Term Loans, PLUS the
outstanding principal balance of the Revolving Credit Loan, PLUS the unused
portion of the Revolving Credit Loan Commitment to an amount that is equal to
or less than the product of (A) EBITDA for the rolling four Borrower fiscal
quarter period consisting of the most recent Borrower fiscal quarter then
ended and the Borrower's three immediately preceding fiscal quarters TIMES
(B) two (2). Any such prepayment shall be applied to the installments of the
Term Loans in the inverse order of their maturities.

               SECTION 2.6.1.6.  If at any time the aggregate principal
amount of the Revolving Credit Loans plus the aggregate stated amount of any
outstanding Letters of Credit and unreimbursed amounts thereunder shall
exceed the Revolving Credit Loan Commitment, the Borrower shall immediately
pay to the Agent in immediately available Dollars the amount of such excess.

               SECTION 2.6.1.7.  In the event that any payment or prepayment
of a Libor Loan under this SECTION 2.6.1 is received on a date other than
the last day of an Interest Period, and after applying such payment or
prepayment to any portion of the Term Loans consisting of a Prime Rate Loan,
such payment or prepayment shall be held by the Agent in a separate account
and be pledged to the Agent as collateral for the Obligations of the
Borrower arising in connection with the Financing Documents until the last
day of the then current Interest Period, at which time the Agent shall apply
such payment or prepayment, for the account of the Lenders in accordance
with their Pro Rata Shares, to the outstanding Libor Loans, for which such
day is an Interest Adjustment Date.

          SECTION 2.6.2. VOLUNTARY PREPAYMENTS.  All or any portion of the
unpaid principal balance of the Loans (other than portions of any Loans
constituting Libor Loans) may be prepaid at any time, without premium or
penalty (other than amounts due under Section 2.9.5,) by giving the Agent at
least 3 days' prior written notice of such prepayment and by a payment to
the Agent for the accounts of the Lenders in accordance with their Pro Rata
Shares of such prepayment in immediately available Dollars by the Borrower;
provided that each such partial payment or prepayment of principal of the
Loans shall be in a principal amount of at least $400,000 or an integral
multiple of $100,000 in excess thereof and provided further that each such
prepayment of the Term Loans shall be applied to the principal installments
of the Term Loans in the inverse order of their maturities.

          SECTION 2.6.3. PREPAYMENT OF LIBOR LOANS.    Notwithstanding
anything to the contrary contained in any Note or in any other agreement
executed in connection herewith or therewith, the Borrower shall be permitted
to prepay any portion of the Loans constituting Libor Loans only in
accordance with SECTION 2.9 hereof.

          SECTION 2.6.4. PERMANENT REDUCTION OF COMMITMENT.  At the
Borrower's option the Commitment and the Revolving Credit Loan Commitment may
be permanently and irrevocably reduced in whole or in part by an amount of at
least $400,000 and to the extent in excess thereof in integral multiples of
$100,000 at any time; provided that (i) the Borrower gives the Agent written
notice of the exercise of such option at least three (3) Business Days prior
to the effective date thereof, (ii) the aggregate outstanding balance of the
Loans, if any, does not

                                       27

<PAGE>

exceed the Commitment and the aggregate outstanding balance of the Revolving
Credit Loans, plus the aggregate outstanding amount of any Letters of Credit
or Letter of Credit Agreement and any unreimbursed drawn amounts thereunder,
if any, does not exceed the Revolving Credit Loan Commitment, both as so
reduced in any such case on the effective date of such reduction and (iii)
the Borrower is not, and after giving effect to such reduction, would not be
in violation of SECTION 2.6.3.  Any such reduction shall concurrently reduce
the Dollar amount of each Lender's Pro Rata Share of the Commitment and the
Revolving Credit Loan Commitment.

     SECTION 2.7.    PAYMENT ON NON-BUSINESS DAYS.  Whenever any payment to
be made hereunder or under any Note shall be stated to be due on a day other
than a Business Day, such payment may be made on the next succeeding Business
Day, and such extension of time shall in such case be included in the
computation of payment of fees, if any, and interest under this Agreement and
under such Note.

     SECTION 2.8.    USE OF PROCEEDS.  (a)  The Borrower shall use the
proceeds of the Term Loans to fund all or a portion of the Intellectual
Property Acquisition and to pay costs incurred by the Borrower in connection
with the closing of the Loans, including without limitation, the Facility Fee
and costs incurred in connection with the Related Transactions and shall use
the proceeds of the Revolving Credit Loans for Borrower's working capital
needs and for Investments permitted by SECTION 5.2.12.  The Borrower shall
obtain any Letters of Credit solely for working capital and general corporate
purposes.

               (b)  No portion of the proceeds of any Loans is to be used,
and no portion of any Letter of Credit is to be obtained, for the purpose of
(a) knowingly purchasing, or providing credit support for the purchase of,
Ineligible Securities from a Section 20 Subsidiary during any period in which
such Section 20 Subsidiary makes a market in such Ineligible Securities, (b)
knowingly purchasing, or providing credit support for the purchase of, during
the underwriting or placement period, any Ineligible Securities being
underwritten or privately placed by a Section 20 Subsidiary, or (c) making,
or providing credit support for the making of, payments of principal or
interest on Ineligible Securities underwritten or privately placed by a
Section 20 Subsidiary and issued by or for the benefit of the Borrower or any
Subsidiary or other Affiliate of the Borrower.

     SECTION 2.9.    SPECIAL LIBOR LOAN PROVISIONS.  The Libor Loans shall be
subject to and governed by the following terms and conditions:

          SECTION 2.9.1. REQUESTS.  Each Request accompanied by an Interest
Rate Election selecting the Libor Rate must be received by the Agent in
accordance with the definition of Interest Rate Election.

          SECTION 2.9.2. LIBOR LOANS UNAVAILABLE.  Notwithstanding any other
provision of this Agreement, if, prior to or on the date on which all or any
portion of the Loans is to be made as or converted into a Libor Loan, any of
the Lenders (or the Agent with respect to (ii) below) shall reasonably
determine (which determination shall be conclusive and binding on the
Borrower), that

                                       28

<PAGE>

          (i)  Dollar deposits in the relevant amounts and for the relevant
     Interest Period are not offered to such Lender in the London interbank
     market,

          (ii)  by reason of circumstances affecting the London interbank
     market, adequate and reasonable means do not exist for ascertaining the
     Adjusted Libor Rate, or

          (iii)  the Adjusted Libor Rate shall no longer represent the
     effective cost to such Lender for Dollar deposits in the London
     interbank market for reasons other than the fact, standing alone, that
     the Adjusted Libor Rate is based on an averaging of rates determined by
     the Agent and that such Lender's rate may exceed such average,

such Lender may elect not to accept any Interest Rate Election electing a
Libor Loan and such Lender shall notify the Agent by telephone or telex
thereof, stating the reasons therefor, not later than the close of business
on the second Business Day prior to the date on which such Libor Loan is to
be made.  The Agent shall promptly give notice of such determination and the
reason therefor to the Borrower, and all or such portion of the Loans, as the
case may be, which are subject to any of SECTION 2.9.2 (i), (ii) through
(iii) as a result of such Lender's determination shall be made as or
converted into, as the case may be, Prime Rate Loans and such Lender shall
have no further obligation to make Libor Loans, until further written notice
to the contrary is given by the Agent to the Borrower.  If such circumstances
subsequently change so that such Lender shall no longer be so affected, such
Lender's obligation to make or maintain its Pro Rata Share of all or any
portion of the Loans as Libor Loans shall be reinstated when such Lender
obtains actual knowledge of such change of circumstances and promptly after
obtaining such actual knowledge such Lender shall forward written notice
thereof to the Agent.  After receipt of such notice, the Agent shall promptly
forward written notice thereof to the Borrower.  Upon or after receipt by the
Borrower of such written notice, the Borrower may submit an Interest Rate
Election in accordance with this Agreement electing an Interest Period ending
no later than the Interest Adjustment Date for the then current Interest
Period for the other Lenders' Pro Rata Shares of Libor Loans and electing the
Libor Rate for such Lenders' or Lender's Pro Rata Share(s) of the Loans as to
which such Lender's or Lenders' obligation(s) to make or maintain its or
their Pro Rata Share(s) of the Loans as Libor Loans was suspended and such
Pro Rata Share(s) shall be converted to Libor Loans in accordance with this
Agreement.  During any period throughout which any of the Lenders has or have
no obligation to make or maintain its or their Pro Rata Share(s) of the Loans
as Libor Loans, no Interest Rate Elections electing the Libor Rate shall be
effective with regard to the Loans to the extent of the Pro Rata Share(s) of
such Lender(s), but shall be effective as to the other Lenders.

          SECTION 2.9.3. LIBOR LENDING UNLAWFUL.  In the event that any
change in applicable laws or regulations (including the introduction of any
new applicable law or regulation) or in the interpretation thereof (whether
or not having the force of law) by any governmental or other regulatory
authority charged with the administration thereof, shall make it unlawful for
any of the Lenders to make or continue to maintain its Pro Rata Share of all
or any portion of the Loans as Libor Loans, each such Lender shall promptly
notify the Agent by telephone or telex thereof, and of the reasons therefor,
and the obligation of such Lender to make or maintain its Pro Rata Share of
the Loans or such portion thereof as Libor Loans shall, upon the happening of
such event, terminate and the Agent shall, by telephonic notice to the
Borrower,

                                       29

<PAGE>

declare that such obligation has so terminated with respect to such Lender,
and such Pro Rata Share of the Loans or any portion thereof to the extent
then maintained as Libor Loans, shall, on the last day on which such Lender
can lawfully continue to maintain such Pro Rata Share of the Loans or any
portion thereof as Libor Loans, automatically convert into Prime Rate Loans
without additional cost to the Borrower.  If circumstances subsequently
change so that such Lender shall no longer be so affected, such Lender's
obligation to make or maintain its Pro Rata Share of all or any portion of
the Loans as Libor Loans shall be reinstated when such Lender obtains actual
knowledge of such change of circumstances, and promptly after obtaining such
actual knowledge such Lender shall forward written notice thereof to the
Agent.  After receipt of such notice, the Agent shall promptly forward
written notice thereof the Borrower.  Upon or after receipt by the Borrower
of such written notice, the Borrower may submit an Interest Rate Election in
accordance with this Agreement electing an Interest Period ending no later
than the Interest Adjustment Date for the then current Interest Period for
the other Lenders' Pro Rata Shares of Libor Loans and electing the Libor Rate
for such Lenders' or Lender's Pro Rata Share(s) of the Loans as to which such
Lender's or Lenders' obligation(s) to make or maintain its or their Pro Rata
Share(s) of the Loans as Libor Loans was suspended and such Pro Rata Share(s)
shall be converted to Libor Loans in accordance with this Agreement.  During
any period throughout which any of the Lenders has or have no obligation to
make or maintain its or their Pro Rata Share(s) of the Loans as Libor Loans,
no Interest Rate Elections electing the Libor Rate shall be effective with
regard to the Loans to the extent of the Pro Rata Share(s) of such Lender(s),
but shall be effective as to the other Lenders.

          SECTION 2.9.4. ADDITIONAL COSTS ON LIBOR LOANS.  The Borrower
further agrees to pay to the Agent for the account of the applicable Lender
or Lenders such amounts as will compensate any of the Lenders for any
increase in the cost to such Lender of making or maintaining (or of its
obligation to make or maintain) all or any portion of its Pro Rata Share of
the Loans as Libor Loans and for any reduction in the amount of any sum
receivable by such Lender under this Agreement in respect of making or
maintaining all or any portion of such Lender's Pro Rata Share of the Loans
as Libor Loans, in either case, from time to time by reason of:

          (i)  any reserve, special deposit or similar requirement against
     assets of, deposits with or for the account of, or credit extended by,
     such Lender, under or pursuant to any law, treaty, rule, regulation
     (including, without limitation, any Regulations of the Board of
     Governors of the Federal Reserve System) or requirement in effect on or
     after the date hereof, any interpretation thereof by any governmental
     authority charged with administration thereof or by any central bank or
     other fiscal or monetary authority or other authority, or any
     requirement imposed by any central bank or such other authority whether
     or not having the force of law but excluding any amount included in any
     Reserve Percentage (as defined in the definition of Adjusted Libor
     Rate); or

          (ii)  any change in (including the introduction of any new)
     applicable law, treaty, rule, regulation or requirement or in the
     interpretation thereof by any official authority, or the imposition of
     any requirement of any central bank, whether or not having the force of
     law, which shall subject such Lender to any tax (other than taxes on net
     income imposed on such Lender), levy, impost, charge, fee, duty,
     deduction or withholding of any kind

                                       30

<PAGE>

     whatsoever or change the taxation of such Lender with respect to making
     or maintaining all or any portion of its Pro Rata Share of the Loans as
     Libor Loans and the interest thereon (other than any change which
     affects, and to the extent that it affects, the taxation of net income
     of such Lender); provided, that with respect to any withholding the
     foregoing shall not apply to any withholding tax described in sections
     1441, 1442 or 3406 of the Code, or any succeeding provision of any
     legislation that amends, supplements or replaces any such section, or to
     any tax, levy, impost, duty, charge, fee, deduction or withholding that
     results from any noncompliance by a Lender with any federal, state or
     foreign law or from any failure by a Lender to file or furnish any
     report, return, statement or form the filing or furnishing of which
     would not have an adverse effect on such Lender and would eliminate such
     tax, impost, duty, deduction or withholding;

In any such event, such Lender shall promptly notify the Agent thereof, and
of the reasons therefor, and the Agent shall promptly notify the Borrower
thereof in writing stating the reasons provided to the Agent by such Lender
therefor and the additional amounts required to fully compensate such Lender
for such increased or new cost or reduced amount as reasonably determined by
such Lender. Such additional amounts shall be payable on each date on which
interest is to be paid hereunder or, if there is no outstanding principal
amount under any of the Notes, within ten (10) Business Days after the
Borrower's receipt of said notice.  Such Lender's certificate as to any such
increased or new cost or reduced amount (including calculations, in
reasonable detail, showing how such Lender computed such cost or reduction)
shall be submitted by the Agent to the Borrower and shall, in the absence of
manifest error, be presumptively correct. In determining any such amount, the
Lender(s) may use any reasonable averaging and attribution methods.
Notwithstanding anything to the contrary set forth above, the Borrower shall
not be obligated to pay any amounts pursuant to this SECTION 2.9.4 as a
result of any requirement or change referenced above with respect to any
period prior to the one hundred and eightieth (180th) day prior to the date
on which the Borrower is first notified thereof (other than any amounts which
relate to any such requirement or change which is adopted with retroactive
effect in which case the Borrower shall be obligated to pay all such amounts
accrued from the date as of which such requirement or change is retroactively
effective).

          SECTION 2.9.5. LIBOR FUNDING LOSSES.  In the event that any payment
or prepayment of a Libor Loan is received on a date other than the last day
of an Interest Period, such payment or prepayment shall, at the request of
the Borrower, be held by the Agent in a separate interest bearing account and
be pledged to the Agent as collateral for the obligations of the Borrower
arising in connection with this Agreement, the Notes and the other Financing
Documents until the end of the then current Interest Period, at which time
the Agent shall apply such payment or prepayment, for the accounts of the
Lenders in accordance with their Pro Rata Shares, to the outstanding Libor
Loans.  Notwithstanding the foregoing, in the event Borrower does not request
the Agent to hold prepayment funds as described in the preceding sentence,
and any of the Lenders shall incur any loss or expense (including, without
limitation, any loss or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund or
maintain all or any portion of the Loans as Libor Loans) as a result of:

                                       31
<PAGE>

          (i)  payment or prepayment by the Borrower of all or any portion of
     any Libor Loan on a date other than the Interest Adjustment Date for such
     Libor Loan, for any reason; provided, however that this clause shall not be
     deemed to grant the Borrower any right to convert a Libor Loan to a Prime
     Rate Loan prior to the end of any Interest Period or to imply such right;

          (ii)  conversion of all or any portion of any Libor Loan on a day
     other than the last day of an Interest Period applicable to such Loan to a
     Prime Rate Loan for any reason including, without limitation, acceleration
     of the Loans upon or after an Event of Default, any Interest Rate Election
     or any other cause whether voluntary or involuntary and whether or not
     referred to or described in this Agreement, other than any such conversion
     resulting solely from application of SECTIONS 2.9.2 or 2.9.3 by any Lender;
     or

          (iii)  any failure by the Borrower to borrow the Loans as Libor Loans
     on the date specified in any Interest Rate Election selecting the Libor
     Rate, other than any such failure resulting solely from application of
     SECTIONS 2.9.2 or 2.9.3 by any Lender;

such Lender shall promptly notify the Agent thereof, and of the reasons
therefor.  Upon the request of the Agent, the Borrower shall pay directly to the
Agent for the account of such Lender such amount as will (in the reasonable
determination of such  Lender, which shall be conclusive in the absence of
manifest error)  reimburse such Lender for such loss or expense.  Each Lender
shall furnish to the Borrower, upon written request from the Borrower received
by the Agent, a written statement setting forth the computation of any such
amounts payable to such Lender under this SECTION 2.9.5.

          SECTION 2.9.6. BANKING PRACTICES.  Each Lender agrees that upon the
occurrence of any of the events described in SECTIONS 2.2.3 and/or 2.9.2, 2.9.4
or 2.9.5, such Lender will exercise all reasonable efforts to take such
reasonable actions at no expense to such Lender (other than reasonable expenses
which are covered by the Borrower's advance deposit of funds with such Lender
for such purpose, or if such Lender agrees, which the Borrower has agreed to pay
or reimburse to such Lender in full upon demand), in accordance with such
Lender's usual banking practices in such situations and subject to any statutory
or regulatory requirements applicable to such Lender, as such Lender may take
without the consent or participation of any other Person to, in the case of an
event described in SECTIONS 2.2.3 and/or 2.9.4 or 2.9.5, mitigate the cost of
such events to the Borrower and, in the case of an event described in SECTIONS
2.9.2(i), (ii) or (iii), to seek Dollar deposits in any other interbank Libor
market in which such Lender regularly participates and in which the applicable
determination(s) described in SECTIONS 2.9.2(i), (ii) or (iii), as the case may
be, does not apply.

          SECTION 2.9.7. BORROWER'S OPTIONS ON UNAVAILABILITY OR INCREASED COST
OF LIBOR LOANS.  In the event of any conversion of all or any portion of any
Lender's Pro Rata Share of any Libor Loans to a Prime Rate Loan for reasons
beyond the Borrower's control or in the event that any Lender's Pro Rata Share
of all or any portion of the Libor Loans becomes subject, under SECTIONS 2.9.4
or 2.9.5, to additional costs, the Borrower shall have the option, subject to
the other terms and conditions of this Agreement, to convert such Lender's Pro
Rata Share to a Prime Rate Loan by making Interest Rate Elections for Interest
Periods which (i) end on the Interest

                                 32
<PAGE>

Adjustment Date for such Libor Loan or (ii) end on Business Days occurring
prior to such Interest Adjustment Date, in which case, at the end of the last
of such Interest Periods any such Libor Rate Loan shall automatically convert
to a Prime Rate Loan and the Borrower shall have no further right to make an
Interest Rate Election with respect to such Prime Rate Loan other than an
Interest Rate Election which is effective on the Interest Adjustment Date for
such Libor Loan.  The Borrower's options set forth in this SECTION 2.9.7 may
be exercised, if and only if the Borrower pays, concurrently with delivery to
the Agent of each such Interest Rate Election and thereafter in accordance
with SECTIONS 2.9.4, 2.9.5 and 2.9.6 all amounts provided for therein to the
Agent in accordance with this Agreement.

          If the Borrower shall, as a result of the requirements of SECTION
2.9.4 above, be required to pay any Lender the additional costs referred to
therein, but not be required to pay such additional costs to the other Lender or
Lenders and the Borrower, in its sole discretion, shall deem such additional
amounts to be material or in the event that Libor Loans from a Lender are
unavailable to the Borrower as a result solely of the provisions of SECTIONS
2.9.2, 2.9.3 or 2.9.4, but are available from the other Lender or Lenders, the
Borrower shall have the right to substitute another bank satisfactory to the
Agent for such Lender which is entitled to such additional costs or which is
relieved from making Libor Loans and the Agent shall use reasonable efforts
(with all reasonable costs of such efforts by the Agent to be borne by the
Borrower) to assist the Borrower to locate such substitute bank.  Any such
substitution shall take place in accordance with SECTION 9.11 and otherwise be
on terms and conditions reasonably satisfactory to the Agent, and until such
time as such substitution shall be consummated, the Borrower shall continue to
pay such additional costs and comply with the above-referenced Sections.  Upon
any such substitution, the Borrower shall pay or cause to be paid to the Lender
that is being replaced, all principal, interest (to the date of such
substitution) and other amounts owing hereunder to such Lender and such Lender
will be released from liability hereunder.

          SECTION 2.9.8. ASSUMPTIONS CONCERNING FUNDING OF LIBOR LOANS.  The
calculation of all amounts payable to the Lenders under this SECTION 2.9 shall
be made as though each Lender  actually funded its relevant Libor Loans through
the purchase of a deposit in the London interbank market bearing interest at the
Libor Rate in an amount equal to that Libor Loan and having a maturity
comparable to the relevant Interest Period and through the transfer of such
deposit from an offshore office of such Lender to a domestic office of such
Lender in the United States of America; provided, however, that each Lender may
fund each of its Libor Loans in any manner it sees fit and the foregoing
assumption shall be utilized solely for the calculation of amounts payable under
this SECTION 2.9.

     SECTION 2.10.   INTEREST RATE PROTECTION.  On or before the Closing Date,
the Borrower shall enter into an interest rate protection arrangement covering
not less than $9,000,000 of the Term Loan.  Such interest rate protection
arrangement may consist of any one or a combination of the following: (i) the
purchase of an interest rate swap arrangement from a financial institution
reasonably acceptable to the Majority Lenders covering such Loans effectively
converting the Borrower's interest payment obligations with respect to such
portion of the Term Loans to a fixed rate per annum satisfactory to the Majority
Lenders for a term expiring not earlier than the second anniversary of the
Closing Date or (ii) the purchase of an interest rate cap from a financial
institution reasonably acceptable to the Majority Lenders covering such Loans at
a cap rate per

                                 33

<PAGE>

annum  satisfactory to the Majority Lenders for a term expiring not earlier
than the second anniversary of the Closing Date.  The other terms and
conditions of any such interest rate swap or interest rate cap shall be
reasonably satisfactory to the Majority Lenders.

the Loan or Advance, including, without limitation, Regulations U, T, and X of
the Board of Governors of the Federal Reserve System; and

          (e)  No Material Adverse Effect has occurred.

                                     ARTICLE 4.

                           REPRESENTATIONS AND WARRANTIES

     SECTION 4.1.    REPRESENTATIONS AND WARRANTIES OF THE BORROWER.  The
Borrower represents and warrants to the Agent and the Lenders that, after giving
effect to the Loans and the application of the proceeds thereof (which
representations and warranties shall survive the making of the Loans) as
follows:

          SECTION 4.1.1. ORGANIZATION AND EXISTENCE.  The Borrower and any
Subsidiary is a corporation, duly organized, validly existing and in good
standing under the laws of the state (or applicable jurisdiction) of its
incorporation or organization and is duly qualified to do business in all
jurisdictions in which such qualification is required, all as noted on EXHIBIT

Effect, and has all  requisite power and authority to conduct its business, to
own its properties and to execute and deliver, and to perform all of its
obligations under the Financing Documents.

          SECTION 4.1.2. AUTHORIZATION AND ABSENCE OF DEFAULTS.  Except as
described on EXHIBIT 4.1.2, the execution, delivery to the Agent and/or the
Lenders and performance by the Borrower and any Subsidiary of the Financing

duly authorized by all necessary corporate and governmental

                                 38

<PAGE>

action and do not and will not (i) require any consent or approval of the
shareholders or board of directors of the Borrower or any Subsidiary which
has not been obtained, (ii) violate any provision of any law, rule,
regulation (including, without limitation, Regulations U and X of the board
of governors of the federal reserve system), order, writ, judgment,
injunction, decree, determination or award presently in effect having
applicability to the Borrower and/or any Subsidiary and/or the articles of
organization or by-laws, as applicable, of the Borrower and/or any
Subsidiary, (iii) result in a material breach of or constitute a material
default under any indenture or loan or credit agreement or any other material
agreement, lease or instrument to which the Borrower and/or any Subsidiary is
or are a party or parties or by  which it or they or its or their properties
may be bound or affected; or (iv) result in, or require, the creation or
imposition of any Lien on any of the Borrower's and/or any Subsidiary's
respective properties or revenues other than Liens granted to the Agent by
any of the Financing Documents securing the Obligations.  The Borrower and
any Subsidiary are in compliance with all such applicable laws, rules,
regulations, orders, writs, judgments, injunctions, decrees, determinations
or awards or any such indentures, other agreements, leases or instruments,
except where the failure to be in compliance does not have a Material Adverse
Effect.

          SECTION 4.1.3. ACQUISITION OF CONSENTS.  Except as noted on EXHIBIT
4.1.3, no authorization, consent, approval, license, exemption of or filing or
registration with any court or governmental department, commission, board,
bureau, agency or instrumentality, domestic or foreign, other than those which
have been obtained, is or will be necessary to the valid execution and delivery
to the Agent and/or the Lenders or performance by the Borrower or any Subsidiary
of any Financing Documents and each of the foregoing which has been obtained is
in full force and effect except where the failure to obtain such authorizations,
consents, approvals, licenses, exemptions or filings would not have a Material
Adverse Effect.

          SECTION 4.1.4. VALIDITY AND ENFORCEABILITY.  Each of the Financing
Documents to which the Borrower or any Subsidiary is a party when delivered
hereunder will constitute the legal, valid and binding obligations of each of
the Borrower and any Subsidiary which is or are a party thereto enforceable
against the Borrower, and any Subsidiary which is or are a party thereto in
accordance with their respective terms except as the enforceability thereof may
be limited by the effect of general principles of equity and bankruptcy and
similar laws affecting the rights and remedies of creditors generally.

          SECTION 4.1.5. FINANCIAL INFORMATION.  The following information with
respect to the Borrower has heretofore been furnished to the Agent:

               SECTION 4.1.5.1.  Audited annual financial statements of
Viewlogic Systems, Inc. prior to its acquisition by Synopsis ("Old Viewlogic")

               SECTION 4.1.5.2. Interim, consolidated balance sheets of the

prior to the Closing for which such statements are available and the related
statements of income, such balance sheets and statements have been prepared and
certified by an Authorized Representative in an Officer's

                                 39

<PAGE>

SECTION 4.1.5.1 and 4.1.5.2 was prepared in accordance with GAAP (subject, in
the case of interim statements, to the absence of footnotes and normal year-end
adjustments) applied on a consistent basis, except as stated therein.  To the
best of the Borrower's knowledge, each of the financial statements referred to
above in SECTIONS 4.1.5.1, 4.1.5.2 and 4.1.5.4 fairly presents the financial
condition or pro forma financial condition, as the case may be, of the Person
being reported on at such dates and is complete and correct in all material
respects and no Material Adverse Effect has occurred since the date thereof.
The Projections were prepared by the Borrower in good faith.

          SECTION 4.1.6. NO LITIGATION.  There are no actions, suits or
proceedings pending or, to the knowledge of the Borrower, threatened against or
affecting the Borrower and/or any Subsidiary or any of their properties before
any court or governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, which if determined adversely to the
Borrower and/or any Subsidiary would draw into question the legal existence of
the Borrower and/or any such Subsidiary and/or the validity, authorization
and/or enforceability of any of the Financing Documents and/or any provision
thereof and/or would reasonably be expected to have a Material Adverse Effect
except those matters, if any, described on EXHIBIT 4.1.6 none of which, in
Borrower's good faith opinion, will (i) have such Material Adverse Effect or
(ii) draw into question (a) the legal existence of the Borrower and/or any such
Subsidiary or (b) the validity, authorization and/or enforceability of any of
the Financing Documents and/or any provision thereof.

          SECTION 4.1.7. REGULATION U.  The Borrower is not engaged in the
business of extending credit for the purpose of purchasing or carrying "margin
stock" within the meaning of Regulation U of the Board of Governors of the
Federal Reserve System (12 CFR Part 221) ("Regulation U"), and does not own and
has no present intention of acquiring any such margin stock or a "margin
security" within the meaning of Regulation U.  None of the proceeds of the Loans
will be used directly or indirectly by the Borrower for the purpose of
purchasing or carrying, or for the purpose of reducing or retiring any
Indebtedness which was originally incurred to purchase or carry, any such margin
security or margin stock or for any other purpose which might constitute the
transaction contemplated hereby a "purpose credit" within the meaning of
Regulation U, or cause this Agreement to violate any other regulation of the
Board of Governors of the Federal Reserve System or the Securities and Exchange
Act of 1934, as amended, or any rules or regulations promulgated under either
said statute.

          SECTION 4.1.8. ABSENCE OF ADVERSE AGREEMENTS.  Neither the Borrower
nor any Subsidiary is a party to any indenture, loan or credit agreement or any
lease or other agreement

                                 40

<PAGE>

or instrument or subject to any corporate or partnership restriction which
would have a Material Adverse Effect.

          SECTION 4.1.9. TAXES.  The Borrower and each Subsidiary has filed all
tax returns (federal, state and local) required to be filed and paid all taxes
shown thereon to be due, including interest and penalties, except for those
taxes, if any, which are being contested in good faith and by appropriate
proceedings, and for which proper reserve or other provision has been made in
accordance with GAAP and except where any failure to file or pay would not have
a Material Adverse Effect on the Borrower or any Subsidiary and except as
described in EXHIBIT 4.1.9.

          SECTION 4.1.10.  ERISA.  Borrower and any Commonly Controlled
Entity do not maintain or contribute to any Plan which  is not in substantial
compliance with ERISA, or any Single  Employer Plan which has incurred any
accumulated funding  deficiency within the meaning of sections 412 and 418 of
the Code or which has applied for or obtained a waiver from the Internal
Revenue Service of any minimum funding requirement under section 412 of the
Code.  Borrower and any Commonly Controlled Entity have not incurred any
liability to the PBGC in connection with any Plan covering any employees of
Borrower or any Commonly Controlled Entity in amount exceeding Fifty Thousand
Dollars ($50,000) in the  aggregate or ceased operations at any facility or
withdrawn from any Plan in a manner which could subject any of them to
liability under sections 4062(e), 4063 or 4064 of ERISA in amount exceeding
Fifty Thousand Dollars ($50,000) in the aggregate, and know of no facts or
circumstance which might give rise to any liability of  Borrower or any
Commonly Controlled Entity to the PBGC under Title IV of ERISA in amount
exceeding Fifty Thousand Dollars ($50,000) in the aggregate.  Borrower and
any Commonly Controlled Entity have not incurred any withdrawal liability in
amount exceeding Fifty Thousand Dollars ($50,000) in the aggregate (including
but not limited to any contingent or secondary withdrawal liability) within
the meaning of sections 4201 and 4202 of ERISA, to any Multiemployer Plan,
and no event has occurred, and there exists no condition or set of
circumstances known to the Borrower, which presents a risk of the occurrence
of any withdrawal from or the partition, termination, reorganization or
insolvency of any Multiemployer Plan which could result in any liability to a
Multiemployer Plan in amount exceeding Fifty Thousand Dollars ($50,000) in
the aggregate.

          Except for payments for which the minimum funding  requirement has
been waived under section 412 of the Code, full payment has been made of all
amounts which Borrower and any  Commonly Controlled Entity are required to have
paid as contributions to any Plan under applicable law or under any plan  or any
agreement relating to any Plan to which Borrower or any  Commonly Controlled
Entity is a party.  Borrower and each Commonly  Controlled Entity have made
adequate provision for reserves to meet contributions that have not been made
because they are not yet due under the terms of any Plan or related agreements.

          Neither Borrower nor any Commonly Controlled Entity has any knowledge,
nor do any of them have any reason to believe, that any Reportable Event which
could result in a liability or liabilities of Fifty Thousand Dollars ($50,000)
or more in the aggregate has occurred with respect to any Plan.

                                 41

<PAGE>
          Neither Borrower nor any Commonly Controlled Entity maintain,
contributes to, or is required to make or accrue a contribution or has within
any of the six preceding years maintained, contributed to or been required to
make or accrue a  contribution to any Plan subject to regulation under Title IV

          SECTION 6.1.6.  If there shall be a default in the performance of the
Borrower's obligations under SECTION 5.1.3 (insofar as such Section requires the
preservation of the corporate existence of the Borrower), any of SECTIONS 5.1.10
through 5.1.13 or SECTIONS 5.2.1, 5.2.3, 5.2.8 OR 5.2.11 of this Agreement; or

          SECTION 6.1.7.  If there shall be any Default in the performance of
any covenant or condition contained in this Agreement or in any of the other
Financing Documents to be observed or performed pursuant to the terms hereof or
any Financing Document, as the case may be, or to the extent such Default would
have a Material Adverse Effect, by the Borrower under

                                 59

<PAGE>

any of the Related Transaction Documents, other than a covenant or condition
referred to in any other subsection of this SECTION 6.1 and such Default
shall continue unremedied or unwaived, (i) in the case of any covenant or
condition contained in SECTIONS 5.2 OR 5.3, for fifteen (15) Business Days,
or (ii) in the case of any other covenant or condition for which no other
grace period is provided, for thirty (30) days, or (iii) in the case of any
other covenant or condition for which another grace period is provided, for
such grace period, or (iv) if any of the representations and warranties made
or deemed made by the Borrower to the Agent and/or any Lender pursuant to any
of the Financing Documents proves to have been false or misleading in any
material respect when made and such falseness or misleading representation
or warranty would be reasonably likely to have a material adverse effect on
the Agent or any Lender or their rights and remedies or a Material Adverse
Effect; or

          SECTION 6.1.8.  If there shall be any attachment of any deposits or
other property of the Borrower and/or any Subsidiary in the possession of any
Lender or any attachment of any other property of the Borrower and/or any
Subsidiary in an amount exceeding $1,000,000, which shall  not be discharged,
vacated or stayed within thirty (30) days of the date of such attachment; or

          SECTION 6.1.9.  Any certification of the financial statements,
furnished to the Agent pursuant to SECTION 5.3.2, shall contain any
qualification; provided, however, that such qualifications will not be deemed an
Event of Default if in each case (i) such certification shall state that the
examination of the financial statements covered thereby was conducted in
accordance with generally accepted auditing standards, including but not limited
to all such tests of the accounting records as are considered necessary in the
circumstances by the independent certified public accountants preparing such
statements, (ii) such financial statements were prepared in accordance with GAAP
and (iii) such qualification does not involve the "going concern" status of the
entity being reported upon.

                                     ARTICLE 7.

                                REMEDIES OF LENDERS

     Upon the occurrence and during the continuance of any one or more of the
Events of Default, the Agent, at the request of the Majority Lenders, shall, by
written notice to the Borrower, declare the obligation of the Lenders to make or
maintain the Loans to be terminated, whereupon the same and the Commitment shall
forthwith terminate, and the Agent, at the request of the Majority Lenders,
shall, by notice to the Borrower, declare the entire unpaid principal amount of
each Note and all fees and interest accrued and unpaid thereon and/or under this
Agreement, and/or any of the other Financing Documents and any and all other
Indebtedness under this Agreement, each Note and/or any of the other Financing
Documents to the Agent and/or any of the Lenders and/or to any holder of all or
any portion of each Note to be forthwith due and payable, whereupon each Note,
and all such accrued fees and interest and other such Indebtedness shall become
and be forthwith due and payable, without presentment, demand, protest or
further notice of any kind, all of which are hereby expressly waived by the
Borrower; provided, however, that upon the occurrence of an Event of Default
under SECTIONS 6.1.2 or 6.1.3,

                                 60

<PAGE>

all of the unpaid principal amount of each Note, all fees and interest
accrued and unpaid thereon and/or under this Agreement and/or under any of
the other Financing Documents and any and all other such Indebtedness of the
Borrower to any of the Lenders and/or to any such holder shall thereupon be
due and payable in full without any need for the Agent and/or any Lender to
make any such declaration or take any action and the Lenders' obligations to
make the Loans shall simultaneously terminate.  The Agent shall, in
accordance with the votes of the Majority Lenders, exercise all remedies on
behalf of and for the account of each Lender and on behalf of its respective
Pro Rata Share of the Loans, its Note and Indebtedness of the Borrower owing
to it or any of the foregoing, including, without limitation, all remedies
available under or as a result of this Agreement, the Notes or any of the
other Financing Documents or any other document, instrument or agreement now
or hereafter securing any Note without any such exercise being deemed to
modify in any way the fact that each Lender shall be deemed a separate
creditor of the Borrower to the extent of its Note and Pro Rata Share of the
Loans and any other amounts payable to such Lender under this Agreement
and/or any of the other Financing Documents and the Agent shall be deemed a
separate creditor of the Borrower to the extent of any amounts owed by the
Borrower to the Agent.

                                     ARTICLE 8.

                                       AGENT

     SECTION 8.1.  APPOINTMENT.  The Agent is hereby appointed as administrative
and collateral agent, hereunder and each Lender hereby authorizes the Agent to
act under the Financing Documents as its Agent hereunder and thereunder,
respectively.  The Agent agrees to act as such upon the express conditions
contained in this Article 8.  The provisions of this Article 8 are solely for
the benefit of the Agent, and, except as expressly provided in SECTION 8.6,
neither the Borrower nor any third party shall have any rights as a third party
beneficiary of any of the provisions hereof.  In performing its functions and
duties under this Agreement and the other Financing Documents to which the Agent
is a party, the Agent shall  act solely as Agent of the Lenders and does not
assume nor shall the Agent be deemed to have assumed any obligation towards or
relationship of agency or trust with or for the Borrower, any of the
Stockholders, any Affiliate or any Subsidiary.

     SECTION 8.2.  POWERS; GENERAL IMMUNITY.

          SECTION 8.2.1.  DUTIES SPECIFIED.  Each Lender irrevocably authorizes
the Agent to take such action on such Lender's behalf, including, without
limitation, to execute and deliver the Financing Documents to which the Agent is
a party and to exercise such powers hereunder and under the Financing Documents
and other instruments and agreements referred to herein as are specifically
delegated to the Agent by the terms hereof and thereof, together with such
powers as are reasonably incidental thereto.  The Agent shall have only those
duties and responsibilities

                                 61

<PAGE>

which are expressly specified in this Agreement or in any of the Financing
Documents and may perform such duties by or through its agents or employees.
The duties of the Agent shall be mechanical and administrative in nature; and
the Agent shall not have by reason of this Agreement or any of the Financing
Documents a fiduciary relationship in respect of any Lender; and nothing in
this Agreement or any of the Security Documents, expressed or implied, is
intended to or shall be so construed as to impose upon the Agent any
obligations in respect of this Agreement or any of the Financing Documents or
the other instruments and agreements referred to herein except as expressly
set forth herein or therein.

          SECTION 8.2.2.  NO RESPONSIBILITY FOR CERTAIN MATTERS.  The Agent
shall not be responsible to any Lender for the execution, effectiveness,
genuineness, validity, enforceability, collectibility or sufficiency of any of
the Financing Documents or any other document, instrument or agreement now or
hereafter executed in connection herewith or therewith, or for any
representations, warranties, recitals or statements made herein or therein or
made in any written or oral statement or in any financial or other statements,
instruments, reports, certificates or any other documents in connection herewith
or therewith by or on behalf of the Borrower, any of the Affiliates, and/or any
Subsidiary to the Agent or any Lender, or be required to ascertain or inquire as
to the performance or observance of any of the terms, conditions, provisions,
covenants or agreements contained herein or therein or as to the use of the
proceeds of the Loans or of the existence or possible existence of any Default
or Event of Default.

          SECTION 8.2.3.  EXCULPATORY PROVISIONS.  Neither the Agent nor any of
its officers, directors, employees or agents shall be liable to any Lender for
any action taken or omitted  hereunder or under any of the Financing Documents,
or in connection herewith or therewith unless caused by its or their gross
negligence or willful misconduct.  If the Agent shall request instructions from
Lenders with respect to any action (including the failure to take an action) in
connection with any of the Financing Documents, the Agent shall be entitled to
refrain from taking such action unless and until the Agent, shall have received
instructions from the Majority Lenders (or all of the Lenders if the action
requires their consent).  Without prejudice to the generality of the foregoing,
(i) the Agent shall be entitled to rely, and shall be fully protected in
relying, upon any communication, instrument or document believed by it to be
genuine and correct and to have been signed or sent by the proper person or
persons, and shall be entitled to rely and shall be protected in relying on
opinions and judgments of attorneys (who may be attorneys for the Borrower, any
of the Affiliates, and/or any Subsidiary), accountants, experts and other
professional advisors selected by it; and (ii) no Lender shall have any right of
action whatsoever against the Agent as a result of the Agent acting or (where so
instructed) refraining from acting under any of the Financing Documents or the
other instruments and agreements referred to herein in accordance with the
instructions of the Majority Lenders (or all of the Lenders if the action
requires their consent).  The Agent shall be entitled to refrain from exercising
any power, discretion or authority vested in it under any of the Financing
Documents or the other instruments and agreements referred to herein unless and
until it has obtained the instructions of the Majority Lenders (or all of the
Lenders if the action requires their consent).

          SECTION 8.2.4.  AGENT ENTITLED TO ACT AS LENDER.  The agency hereby
created shall in no way impair or affect any of the rights and powers of, or
impose any duties or obligations upon, Fleet in its individual capacity as a
Lender hereunder.  With respect to its participation in

                                 62

<PAGE>

the Loans and the Commitment, Fleet shall have the same rights and powers
hereunder as any other Lender and may exercise the same as though it were not
performing the duties and functions delegated to it hereunder, and the term
"Lender" or "Lenders" or any similar term shall, unless the context clearly
otherwise indicates, include Fleet in its individual capacity.  The Agent and
its affiliates may accept deposits from, lend money to and generally engage
in any kind of banking, trust, financial advisory or other business with the
Borrower, any of the Stockholder, or any Affiliate or Subsidiary as if it
were not performing the duties specified herein, and may accept fees and
other consideration from the Borrower and/or any of such other Persons for
services in connection with this Agreement and otherwise without having to
account for the same to Lenders.

     SECTION 8.3.  REPRESENTATIONS AND WARRANTIES; NO RESPONSIBILITY FOR
APPRAISAL OF CREDITWORTHINESS.  Each Lender represents and warrants that it has
made its own independent investigation of the financial condition and affairs of
the Borrower, the Stockholder and any Subsidiaries of any of them in connection
with the making of the Loans hereunder and has made and shall continue to make
its own appraisal of the creditworthiness of the Borrower, the Stockholder and
the Subsidiaries.  The Agent shall not have any duty or responsibility, either
initially or on a continuing basis, to make any such investigation or any such
appraisal on behalf of Lenders or to provide any Lender with any credit or other
information with respect thereto whether coming into its possession before the
making of any Loan or any time or times thereafter (except for information
received by the Agent under SECTION 5.3 hereof which the Agent will promptly
forward to the Lenders), and the Agent shall further not have any responsibility
with respect to the accuracy of or the completeness of the information provided
to any of the Lenders.

     SECTION 8.4.  RIGHT TO INDEMNITY.  Each Lender severally agrees to
indemnify the Agent proportionately to its Pro Rata Share of the Loans, to
the extent the Agent shall not have been reimbursed by or on behalf of the
Borrower, for and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses (including,
without limitation, counsel fees and disbursements) or disbursements of any
kind or nature whatsoever which may be imposed on, incurred by or asserted
against the Agent in performing its duties hereunder or in any way relating
to or arising out of this Agreement and/or any of the other Financing
Documents; 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 Agent's gross
negligence or willful misconduct. If any indemnity furnished to the Agent for
any purpose shall, in the opinion of the Agent, be insufficient or become
impaired, the Agent may call for additional indemnity and cease, or not
commence, to do the acts indemnified against until such additional indemnity
is furnished.

     SECTION 8.5.  PAYEE OF NOTE TREATED AS OWNER.  The Agent may deem and treat
the payee of any Note as the owner thereof for all purposes hereof unless and
until a written notice of the assignment or transfer thereof shall have been
filed with the Agent.  Any request, authority or consent of any person or entity
who, at the time of making such request or giving such authority or consent, is
the holder of any Note shall be conclusive and binding on any subsequent holder,
transferee or assignee of that Note or of any Note or Notes issued in exchange
for such Note.

     SECTION 8.6.  RESIGNATION BY AGENT.

                                 63

<PAGE>

          SECTION 8.6.1.  The Agent may resign from the performance of all
its functions and duties under the Financing Documents at any time by giving
30 days' prior written notice to the Borrower and each of the Lenders.  Such
resignation shall take effect upon the acceptance by a successor Agent, of
appointment pursuant to SECTIONS 8.6.2 and 8.6.3 below or as otherwise
provided below.

          SECTION 8.6.2.  Upon any such notice of resignation, the Majority
Lenders shall appoint a successor Agent, who shall be a Lender and, so long
as no Default or Event of Default exists and is continuing, who shall be
reasonably satisfactory to the Borrower and in any event shall be an
incorporated bank or trust company with a combined surplus and undivided
capital of at least Five Hundred Million Dollars ($500,000,000).

          SECTION 8.6.3.  If a successor Agent shall not have been so
appointed within said 30 day period, the resigning Agent, with the consent of
the Borrower, which shall not be unreasonably withheld or delayed, shall then
appoint a successor Agent, who shall be a Lender and who shall serve as the
Agent, until such time, if any, as the Majority Lenders, and so long as no
Default or Event of Default exists and is continuing, with the consent of the
Borrower, which shall not be unreasonably withheld or delayed, appoint a
successor Agent as provided above.

          SECTION 8.6.4.  If no successor Agent has been appointed pursuant
to SECTIONS 8.6.2 or 8.6.3 by the 40th day after the date such notice of
resignation was given by the resigning Agent, the Majority Lenders shall
promptly thereafter appoint a successor Agent (without regard to the
requirements of SECTIONS 8.6.2 or 8.6.3).  The resigning Agent's resignation
shall become effective upon such successor Agent's acceptance of its
appointment, and such successor Agent shall thereafter perform all the duties
of the Agent under the Financing Documents.

     SECTION 8.7.  SUCCESSOR AGENT.  Upon the acceptance of any appointment
as the Agent hereunder by a successor Agent, that successor Agent shall
thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent and the retiring Agent, shall be
discharged from its duties and obligations as the Agent under the Financing
Documents.  After any retiring Agent's resignation hereunder as the Agent the
provisions of this Article 8 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was the Agent under the Financing
Documents.

                                   ARTICLE 9.

                                 MISCELLANEOUS

     SECTION 9.1.  CONSENT TO JURISDICTION AND SERVICE OF PROCESS.

          SECTION 9.1.1.  Except to the extent prohibited by applicable law,
the Borrower irrevocably:

                                       64
<PAGE>

               SECTION 9.1.1.1.  agrees that any suit, action, or other legal
proceeding arising out of any of the Financing Documents or any of the Loans
may be brought in the courts of record of The Commonwealth of Massachusetts
or any other state(s) in which a portion of the Borrower's or any Subsidiary's
assets sufficient for personal jurisdiction are located or the courts of the
United States located in The Commonwealth of Massachusetts or any other
state(s) in which a portion of the Borrower's or any Subsidiary's assets
sufficient for personal jurisdiction are located;

               SECTION 9.1.1.2.  consents to the jurisdiction of each such
court in any such suit, action or proceeding; and

               SECTION 9.1.1.3.  waives any objection which it may have to
the laying of venue of such suit, action or proceeding in any of such courts.

     For such time as any of the Indebtedness of the Borrower to any Lender
and/or the Agent shall be unpaid in whole or in part and/or the Commitment is
in effect, the Borrower irrevocably designates the registered agent or agent
for service of process of the Borrower as reflected in the records of the
Secretary of State of The Commonwealth of Massachusetts as its registered
agent, and, in the absence thereof, the Secretary of State of The
Commonwealth of Massachusetts as its agent to accept and acknowledge on its
behalf service of any and all process in any such suit, action or proceeding
brought in any such court and agrees and consents that any such service of
process upon such agent and written notice of such service to the Borrower by
registered or certified mail shall be taken and held to be valid personal
service upon the Borrower regardless of where the Borrower shall then be
doing business and that any such service of process shall be of the same
force and validity as if service were made upon it according to the laws
governing the validity and requirements of such service in each such state
and waives any claim of lack of personal service or other error by reason of
any such service.  Any notice,  process, pleadings or other papers served
upon the aforesaid designated agent shall, within three (3) Business Days
after such service, be sent by the method provided therefor under SECTION 9.6
to the Borrower at its address set forth in this Agreement.  EACH OF THE
PARTIES HERETO HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF ANY
DISPUTE BETWEEN THE BORROWER AND THE AGENT AND/OR THE LENDERS WITH RESPECT TO
THE FINANCING DOCUMENTS AND/OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREBY.

     SECTION 9.2.  RIGHTS AND REMEDIES CUMULATIVE.  No right or remedy
conferred upon or reserved to the Agent and/or the Lenders in any of the
Financing Documents is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given under any of
the Financing Documents or now or hereafter existing at law or in equity or
otherwise.  The assertion or employment of any right or remedy under any of
the Financing Documents, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

     SECTION 9.3.  DELAY OR OMISSION NOT WAIVER.  No delay in exercising or
failure to exercise by the Agent and/or the Lenders of any right or remedy
accruing upon any Default or Event of Default shall impair any such right or
remedy or constitute a waiver of any such Default or Event

                                       65
<PAGE>

of Default or an acquiescence therein.  Every right and remedy given by any
of the Financing Documents or by law to the Agent and/or any of the Lenders
may be exercised from time to time, and as often as may be deemed expedient,
by the Agent and/or any of the Lenders.

     SECTION 9.4.  WAIVER OF STAY OR EXTENSION LAWS.  The Borrower covenants
(to the extent that it may lawfully do so) that it will not at any time
insist upon, or plead or in any manner whatsoever claim or take the benefit
or advantage of, any stay or extension law wherever enacted, now or at any
time hereafter in force, which may affect the covenants or the performance of
any of the Financing Documents; and the Borrower (to the extent that it may
lawfully do so) hereby expressly waives all benefit and advantage of any such
law and covenants that it will not hinder; delay or impede the execution of
any power herein granted to the Agent and/or any of the Lenders, but will
suffer and permit the execution of every such power as though no such law had
been enacted, except to the extent the Agent or any Lender is guilty of
willful misconduct or gross negligence.

     SECTION 9.5.  AMENDMENTS, ETC.  No amendment, modification, termination,
or waiver of any provision of any of the Financing Documents nor consent to
any departure by the Borrower therefrom  shall in any event be effective
unless the same shall be in a written notice given to the Borrower by the
Agent and consented to in writing by the Majority Lenders (or by the Agent
acting alone if any specific provision of this Agreement provides that the
Agent, acting alone, may grant such amendment, modification, termination,
waiver or departure) and the Agent shall give any such notice if the Majority
Lenders so consent or direct the Agent to do so; provided, however, that any
such amendment, modification, termination, waiver or consent shall require a
written notice given to the Borrower by the Agent and consented to in writing
by all of the Lenders if the effect thereof is to (i) change any of the
provisions affecting the interest rate on the Loans, (ii) extend or modify
the Commitment, (iii) discharge or release the Borrower from its obligation
to repay all principal due under the Loans or release any collateral or
guaranty for the Loans, (iv) change any Lender's Pro Rata Share of the
Commitment or the Loans, (v) modify this SECTION 9.5, (vi) change the
definition of Majority Lenders, (vii) extend any scheduled due date for
payment of principal, interest or fees or (viii) permit the Borrower to
assign any of its rights under or interest in this Agreement, and then such
waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given.  Any amendment or modification of this
Agreement must be signed by the Borrower, the Agent and at least all of the
Lenders consenting thereto who shall then hold the Pro Rata Shares of the
Loans required for such amendment or modification under this SECTION 9.5 and
the Agent shall sign any such amendment if such Lenders so consent or direct
the Agent to do so provided that any Lender dissenting therefrom shall be
given an opportunity to sign any such amendment or modification.  Any
amendment of any of the Security Documents must be signed by each of the
parties thereto.  No notice to or demand on the Borrower and no consent,
waiver or departure from the terms of this Agreement granted by the Agent
and/or the Lenders in any case shall entitle the Borrower to any other or
further notice or demand in similar or other circumstances.

     SECTION 9.6.  ADDRESSES FOR NOTICES, ETC.  All notices, requests,
demands and other communications provided for hereunder (other than those
which, under the terms of this Agreement, may be given by telephone, which
shall be effective when received verbally) shall be in writing (including
telecopied communication) and mailed (provided that in the case of items

connection with the execution and delivery of the Financing Documents, and
agrees to save the Lenders and the Agent harmless from and against any and
all liabilities with respect to or resulting from any delay in paying or

rights under any of the Financing Documents (the participant's rights against
such Lender in respect of that participation to be those set forth in the
Agreement executed by such Lender in favor of the participant relating
thereto) and all amounts payable by the Borrower hereunder or thereunder
shall be determined as if such Lender had not sold such participation.  Such
Lender may furnish any information concerning the Borrower and any Subsidiary
in the possession of such Lender from time to time to participants (including
prospective participants); provided that such Lender and any participant
comply with the proviso in SECTIONS 9.11.7 and 9.11.8 as if any such
participant was a Substituted Lender.

     SECTION 9.9.  BINDING EFFECT; ASSIGNMENT.  This Agreement shall be
binding upon and inure to the benefit of the Borrower, the Agent and the
Lenders and their respective successors and assigns, except that the Borrower
shall not have the right to assign its rights hereunder or any interest
herein without the prior written consent of the Agent and the Lenders.  This
Agreement and all covenants, representations and warranties made herein
and/or in any of the other Financing Documents shall survive the making of
the Loans, the execution and delivery of the Financing Documents and shall
continue in effect so long as any amounts payable under or in connection with
any of the Financing Documents or any other Indebtedness of the Borrower to
the Agent and/or any Lender remains unpaid or the Commitment remains
outstanding; provided, however, that SECTIONS 2.2.3 and 9.7 shall, except to
the extent agreed to in a pay-off letter by the Agent  and the Lenders in
their complete discretion, survive and remain in full force and effect for 90
days following repayment in full of all amounts payable under or in
connection with all of the Financing Documents and any other such
Indebtedness.

     SECTION 9.10.  ACTUAL KNOWLEDGE.  For purposes of this Agreement,
neither the Agent nor any Lender shall be deemed to have actual knowledge of
any fact or state of facts unless the senior loan officer or any other
officer responsible for the Borrower's account established pursuant to this
Agreement at the Agent or such Lender, shall, in fact, have actual knowledge
of such fact or state of facts or unless written notice of such fact shall
have been received by the Agent or such Lender in accordance with SECTION 9.6.

     SECTION 9.11.  SUBSTITUTIONS AND ASSIGNMENTS.  Upon the request of any
Lender, the Agent and such Lender may assign all or any portion of its Pro
Rata Share of the Commitment and the Loans to a Federal Reserve Bank and may,
subject to the terms and conditions hereinafter set forth, take the actions
set forth below to substitute one or more financial institutions having at
least $500,000,000 in assets (a "Substituted Lender") as a Lender or Lenders
hereunder having an amount of the Loans as specified in the relevant
Substitution Agreement executed in connection therewith; provided that no
Lender, Selling Lender or Substituted Lender shall have a Pro Rata Share of
the Commitment and the Loans in the aggregate of less than $5,000,000 and
Fleet and/or its affiliates shall retain for their own account at least 50%
of the Term Loan and 50% of the Revolving Credit Loan Commitment.

          SECTION 9.11.1.  In connection with any such substitution the
Substituted Lender and the Agent shall enter into a Substitution Agreement in
the form of EXHIBIT 9.11.1 hereto (a "Substitution Agreement") pursuant to
which such Substituted Lender shall be substituted for the Lender requesting
the substitution in question (any such Lender being hereinafter referred to
as a "Selling Lender") to the extent of the reduction in the Selling Lender's
portion of the Loans specified therein.  In addition, such Substituted Lender
shall assume such of the obligations of each Selling Lender under the
Financing Documents as may be specified in such Substitution Agreement and
this Agreement shall be amended by execution and delivery of each
Substitution Agreement to include such Substituted Lender as a Lender for all
purposes under the Financing Documents and to substitute for the then
existing EXHIBIT 1.9 to this Agreement a new EXHIBIT 1.9 in the form of
Schedule A to such Substitution Agreement setting forth the portion of the
Loans belonging to each Lender following execution thereof.  The Agent and
each Substituted Lender shall countersign and accept delivery of each
Substitution Agreement.

          SECTION 9.11.2.  Without prejudice to any other provision of this
Agreement, each Substituted Lender shall, by its execution of a Substitution
Agreement, agree that neither the Agent nor any Lender is any way responsible
for or makes any representation or warranty as to:  (a) the accuracy and/or
completeness of any information supplied to such Substituted Lender in
connection therewith, (b) the financial condition, creditworthiness, affairs,
status or nature of the Borrower, any of the Affiliates and/or any of the
Subsidiaries or the observance by the Borrower, or any other party of any of
its obligations under this Agreement or any of the other Financing Documents
or (c) the legality, validity, effectiveness, adequacy or enforceability of
any of the Financing Documents.

          SECTION 9.11.3.  The Agent shall be entitled to rely on any
Substitution Agreement delivered to it pursuant to this SECTION 9.11 which is
complete and regular on its face as to its contents and appears to be signed
on behalf of the Substituted Lender which is a party thereto, and the Agent
shall have no liability or responsibility to any party as a consequence of
relying

                                       69
<PAGE>

thereon and acting in accordance with and countersigning any such
Substitution Agreement.  The effective date of each Substitution Agreement
shall be the date specified as such therein and each Lender prior to such
effective date shall, for all purposes hereunder, be deemed to have and
possess all of their respective rights and obligations hereunder up to 12:00
o'clock Noon on the effective date thereof.

          SECTION 9.11.4.  Upon delivery to the Agent of any Substitution
Agreement pursuant to and in accordance with this SECTION 9.11 and acceptance
thereof by the Agent (which delivery shall be evidenced and accepted
exclusively and conclusively by the Agent's countersignature thereon pursuant
to the terms hereof without which such Substitution Agreement shall be
ineffective): (i) except as provided hereunder and in SECTION 9.11.5, the
respective rights of each Selling Lender and the Borrower against each other
under the Financing Documents with respect to the portion of the Loans being
assigned or delegated shall be terminated and each Selling Lender and the
Borrower shall each be released from all further obligations to the other
hereunder with respect thereto (all such rights and obligations to be so
terminated or released being referred to in this SECTION 9.11 as "Discharged
Rights and Obligations"); and (ii) the Borrower and the Substituted Lender
shall each acquire rights against each other and assume obligations towards
each other which differ from  the Discharged Rights and Obligations only in
so far as the Borrower and the Substituted Lender have assumed and/or
acquired the same in place of the Selling Lender in question; and (iii) the
Agent, the Substituted Lender and the other Lenders shall acquire the same
rights and assume the same obligations between themselves as they would have
acquired and assumed had such Substituted Lender been an original party to
this Agreement as a Lender possessing the Discharged Rights and Obligations
acquired and/or assumed by it in consequence of the delivery of such
Substitution Agreement to the Agent.

          SECTION 9.11.5.  Discharged Rights and Obligations shall not
include, and there shall be no termination or release pursuant to this
SECTION 9.11 of (i) any rights or obligations arising pursuant to any of the
Financing Documents in respect of the period or in respect of payments
hereunder made during the period prior to the effective date of the relevant
Substitution Agreement or, (ii) any rights or obligations relating to the
payment of any amount which has fallen due and not been paid hereunder prior
to such effective date or rights or obligations for the payment of interest,
damages or other amounts becoming due hereunder as a result of such
nonpayment.

          SECTION 9.11.6.  With respect to any substitution of a Substituted
Lender taking place after the Closing Date, the Borrower shall issue to such
Substituted Lender and to such Selling Lender, new Notes reflecting the
inclusion of such Substituted Lender as a Lender and the reduction in the
respective Loans of such Selling Lender, such new Notes to be issued against
receipt by the Borrower of the existing Notes of such Lender.  The Selling
Lender or the Substituted Lender shall pay to the Agent for its own account
an assignment fee in the amount of $3,000 for each assignment hereunder,
which shall be payable at or before the effective date of the assignment.

          SECTION 9.11.7.  Each Lender may furnish to any financial
institution having at least $500,000,000 in assets which such Lender proposes
to make a Substituted Lender or to a

                                       70
<PAGE>

Substituted Lender any information concerning such Lender, the Borrower,
Stockholders and any Subsidiary in the possession of that Lender from time to
time; provided that any Lender providing any confidential information about
the Borrower, any of the Stockholders and/or any Subsidiary to any such
financial institution shall first obtain such financial institution's
agreement to keep confidential any such confidential information.

          SECTION 9.11.8.  (a)  Each of the Lenders agrees, subject to
SECTION 9.11.7., that it will use its best efforts not to disclose without
the prior consent of the Borrower any information with respect to the
Borrower or any of its Subsidiaries which is furnished pursuant to this
Agreement; PROVIDED, that any Lender may disclose any such information (a) as
has become generally available to the public or has become properly available
to such Lender on a non-confidential basis, (b) as may be required or
appropriate in any report, statement or testimony submitted to any municipal,
state or Federal regulatory body having or claiming to have jurisdiction over
such Lender or to the Federal Reserve Board, the Federal Deposit Insurance
Corporation, the NAIC or similar organizations (whether in the United States
or elsewhere) or their successors, (c) as may be required or appropriate in
response to any summons or subpoena or in connection with any litigation, (d)
in order to comply with any law, order, regulation or ruling applicable to
such Lender, and (e) to any prospective transferee in connection with any
contemplated transfer of any of the Loans or any interest therein by such
Lender; PROVIDED, that such prospective transferee agrees to be bound by the
provisions in this SECTION 9.11.8 to the same extent as such Lender.

                     (b) The Borrower hereby acknowledges and agrees that
each Lender may share with its auditors, counsel, other professional advisors
and any of its Affiliates any information related to the Borrower or any of
its Subsidiaries (including, without limitation, any nonpublic customer
information regarding the creditworthiness of the Borrower and its
Subsidiaries), provided that Lender shall have made such Persons aware of
Section 9.10.8 and such Persons shall have agreed to be subject to the
provisions of this SECTION 9.11.8 to the same extent as such Lender.

     SECTION 9.12.  PAYMENTS PRO RATA.  The Agent agrees that promptly after
its receipt of each payment from or on behalf of the Borrower in respect of
any obligations of the Borrower  hereunder it shall distribute such payment
to the Lenders pro rata based upon their respective Pro Rata Shares, if any,
of the obligations with respect to which such payment was received.  Each of
the Lenders agrees that, if it should receive any amount hereunder (whether
by voluntary payment, by realization upon security, by the exercise of the
right of setoff under SECTION 2.5.2 or otherwise or banker's lien, by
counterclaim or cross action, by the enforcement of any right under the
Financing Documents, or otherwise), which is applicable to the payment of the
Obligations of a sum which with respect to the related sum or sums received
by other Lenders is in a greater proportion than the total amount of such
Obligation then owed and due to such Lender bears to the total amount of such
Obligation then owed and due to all of the Lenders immediately prior to such
receipt, except for any amounts received pursuant to SECTION 2.2.3, then such
Lender receiving such excess payment shall purchase for cash without recourse
or warranty from the other Lenders an interest in the Obligations of the
Borrower to such Lenders in such amount as shall result in a proportional
participation by all the Lenders in such amount; provided further, however,
that if all or any portion of such excess amount is thereafter recovered from
such

                                       71
<PAGE>

Lender, such purchase shall be rescinded and the purchase price restored to
the extent of such recovery, but without interest.

     SECTION 9.13.  INDEMNIFICATION.  The Borrower irrevocably agrees to and
does hereby indemnify and hold harmless Agent and each of the Lenders, their
agents or employees and each Person, if any, who controls any of the Agent
and the Lenders within the meaning of Section 15 of the Securities Act of
1933, as amended, and each and all and any of them (the "Indemnified
Parties"), against any and all losses, claims, actions, causes of action,
damages or liabilities (including any amount paid in settlement of any
action, commenced or threatened and any amount described in SECTION 8.4)
(collectively, the "Damages"), joint or several, to which they, or any of
them, may become subject under statutory law or at common law, and to
reimburse the Indemnified Parties for any legal or other out-of-pocket
expenses reasonably incurred by it or them in connection with investigating,
preparing for or defending against any of the Indemnified Parties, insofar as
such losses, claims, damages, liabilities or actions arise out of or are
related to any act or omission of the Borrower and/or any Subsidiary with
respect to any of (i) the Related Transactions, (ii) any of the Financing
Documents, (iii) any of Loans, (iv) any use made or proposed to be made with
the proceeds of the Loans, (v) any acquisition or proposed acquisition or any
other similar business combination or proposed business combination by the
Borrower and/or any of its Subsidiaries and/or its Affiliates (other than the
Sprout Group not related to the Related Transactions) (whether by acquisition
or exchange of capital stock or other securities or by acquisition of all or
substantially all of the assets of any Person), (vi) any offering of
securities by the Borrower and/or any Subsidiary after the date hereof and/or
in connection with the Securities and Exchange Act of 1933 and/or (vii) any
failure to comply with any applicable federal, state or foreign governmental
law, rule, regulation, order or decree, including without limitation, any
Damages which arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact with respect to matters relative to any
of the foregoing contained in any document distributed in connection
therewith, or the omission or alleged omission to state in any of the
foregoing a material fact necessary to make the statements therein, in the
light of the circumstances under which they were made, not misleading, but
excluding any Damages to the extent arising from or due to, as determined in
a final nonappealable judgment by a court of competent jurisdiction, the
gross negligence or willful misconduct of any of the Indemnified Parties;
provided, however, that notwithstanding the foregoing, no Indemnified Party
shall have any liability (whether direct or indirect, in contract or tort of
otherwise to the Borrower, any Affiliates or any Subsidiaries or to their
respective security holders or creditors except for direct (as opposed to
consequential damages) determined in a final nonappealable judgment by a
court of competent jurisdiction to have resulted from such Indemnified
Party's gross negligence or willful misconduct.  In the case of an
investigation, litigation or proceeding to which the indemnity described in
this paragraph applies, such indemnity shall be effective whether or not such
investigation, litigation or proceeding is brought by the Borrower, any
Affiliates or any Subsidiary or to their respective security holders or
creditors or an Indemnified Party or an Indemnified Party is otherwise a
party thereto and whether or not the Related Transaction and the transactions
contemplated by the Financing Documents are consummated.

     Promptly upon receipt of notice of the commencement of any action, or
information as to any threatened action against any of the Indemnified
Parties in respect of which indemnity or reimbursement may be sought from the
Borrower on account of the agreement contained in this

                                       72
<PAGE>

SECTION 9.13, notice shall be given to the Borrower in writing of the
commencement or threatening thereof, together with a copy of all papers
served, but the omission so to notify the Borrower of any such action shall
not release the Borrower from any liability which it may have to such
Indemnified Parties unless, and only to the extent that, such omission
materially prejudiced Borrower's ability to defend against such action.

     In case any such action shall be brought against any of the Indemnified
Parties, the Borrower shall be entitled to participate in (and, to the extent
that it shall wish, to select counsel and to direct) the defense thereof at
its own expense.  Any of the Indemnified Parties shall have the right to
employ its or their own counsel in any case, but the fees and expenses of
such counsel shall be at the expense of such Indemnified Party unless the
employment of such counsel shall have been authorized in writing by the
Borrower in connection with the defense of such action or the Borrower shall
not have employed counsel to have charge of the defense of such action or
such Indemnified Party shall have received an opinion from an independent
counsel that there may be defenses available to it which are different from
or additional to those available to the Borrower (in which case the Borrower
shall not have the right to direct the defense of such action on behalf of
such Indemnified Party), in any of which events the same shall be borne by
the Borrower.  If any Indemnified Party settles any claim or action with
respect to which the Borrower has agreed to indemnify such Indemnified Party
pursuant to the terms hereof, the Borrower shall have no liability pursuant
to this SECTION 9.13 to such Indemnified Party with respect to such claim or
action unless the Borrower shall have consented in writing to the terms of
such settlement.

     The provisions of SECTION 9.13 shall be effective only to the fullest
extent permitted by law.  The provisions of this SECTION 9.13 shall continue
in effect and shall survive (among other events), until the applicable
statute of limitations has expired, any termination of this Agreement,
foreclosure, a deed in lieu transaction, payment and satisfaction of the
Obligations of Borrower, and release of any collateral for the Loans.

     SECTION 9.13.  GOVERNING LAW.  This Agreement and each Note shall be
governed by, and construed in accordance with, the laws of The Commonwealth
of Massachusetts without regard to such state's conflict of laws rules.

     SECTION 9.15.  SEVERABILITY OF PROVISIONS.  Any provision of this
Agreement which is prohibited or unenforceable in any jurisdiction shall, as
to such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

     SECTION 9.16.  HEADINGS.  Article and Section headings in this Agreement
are included herein for convenience of reference only and shall not
constitute a part of this Agreement for any other purpose.

     SECTION 9.17.  COUNTERPARTS.  This Agreement may be executed and
delivered in any number of counterparts each of which shall be deemed an
original, and this Agreement shall be effective when at least one counterpart
hereof has been executed by each of the parties hereto.

[Insert Maximum Amount of                              _______ __, 19__
Lender's pro Rata Share of
revolving credit loan
Commitment]

     FOR VALUE RECEIVED, VIEWLOGIC SYSTEMS, INC., a Delaware corporation with
a business address of 293 Boston Post Road West, Marlboro, MA 01752-4615
(hereinafter referred to as the "Borrower"), promises to pay to the order of
[insert name of Lender], [a national banking association organized and existing
under the laws of the United States of America] [a ________ banking corporation
____________] (the "Lender"), at the Lender's head office located at [insert
address] or to FLEET NATIONAL BANK or any successor agent under the Loan
Agreement (defined below) (the "Agent") in accordance with the Loan Agreement
(defined below), the lesser of (i) the principal sum of [insert Lender's Pro
Rata Share of the Revolving Credit Loan Commitment] ($__________.00), or (ii)
the aggregate unpaid principal amount of all advances of funds under the
Revolving Credit Loan made by the Lender to the Borrower or by the Lender
through the Agent to the Borrower pursuant to that certain Loan Agreement dated
as of the date hereof by and among the Borrower, the Agent, the other Lenders
party thereto and the Lender, as the same may be amended (the "Loan Agreement").

     The Borrower shall pay in full all unpaid principal, interest, fees and
other amounts due under this Note on the Revolving Credit Repayment Date.

     The Borrower promises to pay to the order of the Lender interest before
and after maturity on the principal amount of this Note outstanding from time
to time from the date hereof until payment in full of all principal,
interest, fees and other sums due under this Note in accordance with the Loan
Agreement.

     Upon the occurrence and during the continuance of any Event of Default
each Prime Rate Loan evidenced by this Note, shall bear interest, payable on
demand, at a floating interest rate per annum equal to two percent (2.0%)
above Effective Prime and each Libor Loan evidenced by this Note shall bear
interest at the Libor Rate plus two percent (2.0%).  In addition, in the
event that the Borrower fails to pay any amount of principal or  interest
hereof within ten (10) days after such payment is due, the Borrower shall pay
to the Lender upon demand by the Agent or the Lender, a late charge in an
amount equal to five percent (5%) of such amount of principal or interest.

<PAGE>

     Principal, interest, fees and other sums are payable in immediately
available Dollars to the Agent at its address set forth in the Loan Agreement
or as otherwise directed in writing from the Agent to the Borrower.

     This Note is one of the Revolving Credit Notes referred to in, and is
entitled to the benefits of, the Loan Agreement.  The applicable terms and
provisions of the Loan Agreement are incorporated herein by reference as if
fully set forth herein.  In the event of any conflict between any provision
of this Note and any provision(s) of the Loan Agreement, such provision(s) of
the Loan Agreement shall control.  Each capitalized term used in this Note
and not expressly defined in this Note shall have the meaning ascribed to
such term in the Loan Agreement.  The Loan Agreement, among other things,
contains provisions for acceleration of the maturity of this Note upon the
happening of certain stated events and also for prepayments on account of
principal of this Note prior to the maturity of this Note upon the terms and
conditions specified in the Loan Agreement.

     This Note is secured by the Security Documents.

     If this Note shall not be paid when due and shall be placed by the
holder hereof in the hands of an attorney for collection, through legal
proceedings or otherwise, the Borrower will pay reasonable attorneys' fees to
the holder hereof together with reasonable costs and expenses of collection.

     All provisions of this Note and any other agreements between the
Borrower and the Lender are expressly subject to the condition that in no
event, whether by reason of acceleration of maturity of the Indebtedness
evidenced by this Note or otherwise, shall the amount paid or agreed to be
paid to the Lender which is deemed interest under applicable law exceed the
maximum permitted rate of interest under applicable law (the "Maximum
Permitted Rate"), which shall mean the law in effect on the date of this
Note, except that if there is a change in such law which results in a higher
Maximum Permitted Rate, then this Note shall be governed by such amended law
from and after its effective date.  In the event that fulfillment of any
provision of this Note, or the Loan Agreement or any document, instrument or
agreement providing security for this Note results in the rate of interest
charged hereunder being in excess of the Maximum Permitted Rate, the
obligation to be fulfilled shall automatically be reduced to eliminate such
excess.  If, notwithstanding the foregoing, the Lender receives an amount
which under applicable law would cause the interest rate hereunder to exceed
the Maximum Permitted Rate, the portion thereof which would be excessive
shall automatically be deemed a prepayment of and be applied to the unpaid
principal balance of this Note to the extent of then outstanding Prime Rate
Loans and not a payment of interest and to the extent said excessive portion
exceeds the outstanding principal amount of Prime Rate Loans, said excessive
portion shall be repaid to the Borrower.

     The Borrower expressly waives presentment, notice of acceleration and
intent to accelerate, demand for payment and protest and notice of protest
and nonpayment.

Loan Commitment]

     FOR VALUE RECEIVED, VIEWLOGIC SYSTEMS, INC., a Delaware corporation,

01752-4615 (hereinafter referred to as the "Borrower") promises to pay the
principal sum of [insert Lender's Pro Rata Share of the Term Loan]
($_________.00) to the order of [insert name of Lender], [a national banking
association organized and existing under the laws of the United States of
America] [a _________ corporation] (the "Lender"), at the Lender's head
office located at [insert address] or to FLEET NATIONAL BANK or any successor
Agent under the Loan Agreement (defined below), as Agent for the Lender (the
"Agent"), in accordance with that certain Loan Agreement dated as of the date
hereof by and among the Borrower, the Agent, the other Lenders party thereto
and the Lender, as amended from time to time (the "Loan Agreement").

     The Borrower promises to pay to the order of the Lender interest before
and after maturity on the principal amount of this Note outstanding from time
to time from the date hereof until payment in full of all principal,
interest, fees and other sums due under this Note in accordance with the
terms of the Loan Agreement.

     The Borrower shall make payments of principal, interest, fees and other
amounts in accordance with the Loan Agreement and shall pay in full all
unpaid principal, interest, fees and other amounts due under this Note on the
Term Loan Repayment Date.

     This Note is secured by the Security Documents.

     Upon the occurrence and during the continuance of any Event of Default
each Prime Rate Loan evidenced by this Note shall bear interest, payable on
demand, at a floating interest rate per annum equal to two percent (2.0%)
above Effective Prime and each Libor Loan evidenced by this Note shall bear
interest at the Libor Rate plus two percent (2.0%).  In addition, in the
event that the Borrower fails to pay any amount of principal or interest
hereof within ten (10) days after such payment is due, the Borrower shall
pay to the Lender upon demand by the Agent or the Lender, a late charge in an
amount equal to five percent (5%) of such amount of principal or interest.

<PAGE>

     Principal, interest, fees and other sums are payable in immediately
available Dollars to the Agent at its address set forth in the Loan Agreement
or as otherwise directed in writing from the Agent to the Borrower.

     This Note is one of the Term Notes referred to in, and is entitled to
the benefits of, the Loan Agreement.  The applicable terms and provisions of
the Loan Agreement are incorporated herein by reference as if fully set forth
herein.  In the event of any conflict between any provisions of this Note and
any provision(s) of the Loan Agreement, such provision(s) of the Loan
Agreement shall control.  Each capitalized term used in this Note and not
expressly defined in this Note shall have the meaning ascribed to such term
in the Loan Agreement.  The Loan Agreement, among other things, contains
provisions for acceleration of the maturity of this Note upon the happening
of certain stated events and also for prepayments on account of principal of
this Note prior to the maturity of this Note upon the terms and conditions
specified in the Loan Agreement.

     If this Note shall not be paid when due and shall be placed by the
holder hereof in the hands of an attorney for collection, through legal
proceedings or otherwise, the Borrower will pay reasonable attorneys' fees to
the holder hereof together with reasonable costs and expenses of collection.

     All provisions of this Note and any other agreements between the
Borrower and the Lender are expressly subject to the condition that in no
event, whether by reason of acceleration of maturity of the Indebtedness
evidenced by this Note or otherwise, shall the amount paid or agreed to be
paid to the Lender which is deemed interest under applicable law exceed the
maximum permitted rate of interest under applicable law (the "Maximum
Permitted Rate"), which shall mean the law in effect on the date of this
Note, except that if there is a change in such law which results in a higher
Maximum Permitted Rate, then this Note shall be governed by such amended law
from and after its effective date.  In the event that fulfillment of any
provision of this Note, or the Loan Agreement or any document, instrument or
agreement providing security for this Note results in the rate of interest
charged hereunder being in excess of the Maximum Permitted Rate, the
obligation to be fulfilled shall automatically be reduced to eliminate such
excess.  If, notwithstanding the foregoing, the Lender receives an amount
which under applicable law would cause the interest rate under this Note to
exceed the Maximum Permitted  Rate, the portion thereof which would be
excessive shall automatically be deemed a prepayment of and be applied to the
unpaid principal balance of this Note to the extent of then outstanding Prime
Rate Loans and not a payment of interest and to the extent said excessive
portion exceeds the outstanding principal amount of Prime Rate Loans, said
excessive portion shall be repaid to the Borrower.

     The Borrower expressly waives presentment, notice of acceleration and
intent to accelerate, demand for payment and protest and notice of protest
and nonpayment.

     This Note shall for all purposes be governed by and construed in
accordance with the laws of The Commonwealth of Massachusetts without regard
to such state's conflict of laws rules.

Default or Event of Default under the Agreement which is continuing as of the
effective date of the Transaction, the Lender hereby waives the Borrower's
compliance with SECTION 5.2.12 of the Agreement solely as such section pertains

future variance by the Borrower from the terms of the Agreement.

         5. This Amendment shall take effect as of the Effective Date upon
receipt by the Agent of the last item specified below (other than any item
expressly deferred or waived in writing by the Agent):

Agreement in that document, or in any related document, shall mean the Agreement
as amended by this Amendment. Except as expressly provided in this Amendment,
the execution and delivery of this Amendment does not and will not amend, modify

noncompliance with the provisions of the Agreement, and, except as specifically
provided in this Amendment, the Agreement shall remain in full force and effect.
This Amendment may be executed in one or more counterparts with the same effect
as if the signatures hereto and thereto were upon the same instrument.

         WHEREAS, the parties have entered into a Loan Agreement dated as of

pursuant to which Lender made a Term Loan to Borrower in the principal amount of

the maximum principal amount of $6,000,000.00;

         WHEREAS, Borrower and Lender have agreed to make certain modifications

         NOW THEREFORE, in consideration of the foregoing premises and the
mutual benefits to be derived by Borrower and Agent from a continuing
relationship under the Agreement and for other good and valuable consideration,
the receipt and adequacy of which are hereby acknowledged, the parties hereto
agree that the Agreement is hereby amended as follows:

         1. Section 1.1 of the Agreement is hereby amended by deleting the
definition of "Excess Cash Flow" in its entirety and replacing it with the

    Period, MINUS the sum of (i) the amount equal to the payments included in
    Total Debt Service paid during such Fiscal Period, (ii) to the extent not
    included in Total Debt Service, all Capital Expenditures permitted under
    SECTION 5.2.17 and paid during such Fiscal Period, (iii) voluntary principal
    prepayments of the Term Loans made during such Fiscal Period, (iv) taxes
    payable during such Fiscal Period and (v) PLUS or MINUS changes in working

    January 1, 2000, if at the end of any such Fiscal Period, the Leverage Ratio
    is at any time greater than 2.0:1, Borrower shall prepay to Agent for the
    accounts of Lenders in accordance with their Pro Rata Shares an amount of
    the outstanding principal balances of the Term Loans equal to (i) fifty

    jointly and severally liable for the Obligations and new Notes
    (collectively, the "NEW CREDIT DOCUMENTS") and grant Liens ("ADDITIONAL
    LIENS") in substantially all assets of each such Post-Merger Shareholder.

    thereto as Agent may reasonably request, and (z) be in form, scope and
    substance reasonably satisfactory to Agent. All such Liens or instruments
    related thereto shall be duly recorded or filed in such manner and in such

         SECTION 5.2.22.2 cause each holder of an equity interest in Borrower
    ("HOLDER") which prior to such merger has been pledged to Agent as security
    for the Obligations (the "PRE-MERGER PLEDGED STOCK") to pledge all of its
    equity interests in each Post-Merger Shareholder in exchange and in
    substitution for the Pre-Merger Pledged Stock. All such pledges shall be
    pledged pursuant to stock pledge agreements, substantially in the form and
    substance of the stock pledge agreements dated as of October 2, 1998
    executed by members of the Sprout Group, and such other documentation,
    including, without limitation, stock powers and other instruments of
    transfer and/or assignment as Agent may reasonably request, in form and
    substance reasonably satisfactory to Agent (all such documentation,
    collectively, the "ADDITIONAL PLEDGE AGREEMENTS") and such pledges shall
    constitute valid and enforceable first priority perfected Liens, superior to
    and prior to the rights of all third Persons and subject to no other Liens,
    in favor of Agent (or such other trustee or sub-agent as may be required or
    desired under local law) for the ratable benefit of Agent and Lenders. In
    addition, Borrower will cause to be delivered to Agent legal opinions from
    counsel to each such Holder covering such matters as Agent may reasonably
    request in form, scope and substance reasonably satisfactory to Agent which
    shall (x) be addressed to Agent and each of Lenders, (y) cover various
    matters regarding the execution, delivery and performance of the Additional
    Pledge Agreements, as well as the perfection and priority of the pledges and
    such other matters incident thereto as Agent may reasonably request, and (z)
    be in form, scope and substance reasonably satisfactory to Agent. The
    Additional Pledge Agreements or instruments related thereto shall be duly
    recorded or filed in such manner and in such places as are required by law
    to create, maintain, effect, perfect, preserve, maintain and protect the
    pledges evidenced thereby and all taxes, fees and other charges payable in
    connection therewith shall be paid in full.
