$20,000,000.00              Galion, Ohio                    ______________, 2000

                  FOR VALUE RECEIVED, the undersigned promises to pay to the
order of THE HUNTINGTON NATIONAL BANK (hereinafter called the "Bank," which term
shall include any holder hereof) at such place as the Bank may designate or, in
the absence of such designation, at any of the Bank's offices, the sum of Twenty
Million Dollars ($20,000,000.00) or so much thereof as shall have been advanced
by the Bank at any time and not thereafter repaid (hereinafter referred to as
"Principal Sum") together with interest as hereinafter provided and payable at
the time and in the manner hereinafter provided. The proceeds of the loan
evidenced hereby may be advanced, repaid and readvanced in partial amounts
during the term of this revolving note (this "Note") and prior to maturity. Each
such advance shall be made to the undersigned upon receipt by the Bank of the
undersigned's application therefor and disbursement instructions, which shall be
in such form as the Bank shall from time to time prescribe. The Bank shall be
entitled to rely on any oral or telephonic communication requesting an advance
and/or providing disbursement instructions hereunder, which shall be received by
it in good faith from anyone reasonably believed by the Bank to be the
undersigned, or the undersigned's authorized agent. The undersigned agrees that
all advances made by the Bank will be evidenced by entries made by the Bank into
its electronic data processing system and/or internal memoranda maintained by
the Bank. The undersigned further agrees that the sum or sums shown on the most
recent printout from the Bank's electronic data processing system and/or on such
memoranda shall be rebuttably presumptive evidence of the amount of the
Principal Sum and of the amount of any accrued interest.

         This Note is executed and the advances contemplated hereunder are to be
made pursuant to a Second Amended and Restated Loan and Security Agreement by
and between the undersigned and the Bank dated October 22, 1999 (as amended,
restated, modified or otherwise supplemented from time to time, herein the "Loan
Agreement"), to which reference is hereby
<PAGE>

made for a more complete statement of the terms and conditions contained
therein. Terms defined in the Loan Agreement and not otherwise defined herein
are used herein with the meanings ascribed to such terms in the Loan Agreement.

         This Note is given in substitution for, and replacement of, that
certain Amended and Restated Revolving Note dated as of October 22, 1999, in the
original principal sum of $10,000,000.00, and not as a novation thereof.

INTEREST
--------

         Prior to maturity, interest will accrue on the unpaid balance of the
Principal Sum at a variable rate of interest per annum, as selected by the
undersigned in accordance with this Note (hereinafter called the "Contract
Rate"), which shall change in the manner set forth below, equal to:

         (1)      the Prime Commercial Rate (as hereinafter defined) minus 0.50
         percentage points  (the "Prime Rate"); or                   -----

         (2)      2.00 percentage points in excess of the Daily LIBOR (as
         hereinafter defined).

         Initially, interest shall accrue hereunder based upon the Daily LIBOR.
The undersigned shall give the Bank written notice of each request to change the
interest index from the Daily LIBOR to the Prime Commercial Rate, or vice versa,
or to request disbursement of an advance with respect to which interest shall
accrue at a rate calculated with reference to the Daily LIBOR, no later than
three (3) Banking Days (as hereinafter defined) prior to the date of the
proposed change or the requested date of disbursement, as the case may be. All
such written notices shall be directed by the undersigned to the Bank's officer
who is handling the undersigned's obligations on behalf of the Bank and must be
received by the Bank at least three (3) Banking Days prior to the date of the
change or the requested date of disbursement.

         Subject to any maximum or minimum interest rate limitation specified
herein or by applicable law, the Contract Rate shall change automatically
without notice to the undersigned immediately on each Banking Day with each
change in the Prime Commercial Rate or in the Daily LIBOR or the Reserve
Requirement, as applicable, with any change thereto effective as of the opening
of business on the day of the change.

         If the obligation evidenced by this Note is not paid at maturity,
whether maturity occurs by lapse of time, demand, acceleration or otherwise, the
unpaid balance of the Principal Sum and any unpaid interest shall, thereafter
until paid, bear interest at a rate equal to 2.00 percentage points in excess of
the Contract Rate.

         As used herein, "Prime Commercial Rate" shall mean the rate established
by the Bank
<PAGE>

from time to time based on its consideration of economic, money market, business
and competitive factors, and it is not necessarily the Bank's most favored rate.

         As used herein, "Daily LIBOR" shall mean the rate obtained by dividing:
(1) actual or estimated per annum rate, or the arithmetic mean of the per annum
rates, of interest for deposits in U.S. dollars for one (1) month periods, as
offered and determined by the Bank in its sole discretion based upon information
which appears on page LIBOR01, captioned British Bankers Assoc. Interest
Settlement Rates, of the Reuters America Network, a service of Reuters America
Inc. (or such other page that may replace that page on that service for the
purpose of displaying London interbank offered rates; or, if such service ceases
to be available, such other reasonably comparable money rate service as the Bank
may select) or upon information obtained from any other reasonable procedure, on
each date the Daily LIBOR is determined; by (2) a percentage (the "Reserve
Requirement") equal to one hundred percent minus the stated maximum rate
(expressed as a percentage), if any, of all reserve requirements (including,
without limitation, any marginal, emergency, supplemental, special or other
reserves) that is specified on each date the Daily LIBOR is determined by the
Board of Governors of the Federal Reserve System (or any successor agency
thereto) for determining the maximum reserve requirement with respect to
eurocurrency funding (currently referred to as "Eurocurrency liabilities" in
Regulation D of such Board) maintained by a member bank of such System, or any
other regulations or any governmental authority having jurisdiction with respect
thereto, all as conclusively determined by the Bank, absent manifest error, such
sum to be rounded up, if necessary, to the nearest whole multiple of
one-sixteenth of one percent (1/16 of 1.0%) per annum.

         As used herein, "Banking Day" shall mean any day other than a Saturday
or a Sunday on which banks are open for business in Columbus, Ohio, and on which
banks in London, England, settle payments.

         All interest shall be calculated on the basis of a 360 day year for the
actual number of days the Principal Sum or any part thereof remains unpaid.
There shall be no penalty for prepayment. The amount of any payment shall first
be applied to the payment of any interest which is due.

         In the event that the Bank reasonably determines that by reason of (1)
any change arising after the date of this Note affecting the interbank
eurocurrency market or affecting the position of the Bank with respect to such
market, adequate and fair means do not exist for ascertaining the applicable
interest rates by reference to which the Daily LIBOR then being determined is to
be fixed, (2) any change arising after the date of this Note in any applicable
law or governmental rule, regulation or order (or any interpretation thereof,
including the introduction of any new law or governmental rule, regulation or
order), or (3) any other circumstance affecting the Bank or the interbank market
(such as, but not limited to, official reserve requirements required by
Regulation D of the Board of Governors of the Federal Reserve System), the Daily
LIBOR plus the applicable spread shall not represent the effective pricing to
the Bank of accruing interest based upon the Daily LIBOR, then, and in any such
event, interest shall accrue hereunder as of the effective date of any such
determination at a rate calculated with reference to the Prime Commercial Rate
(as set forth above) and the ability of the undersigned to request that interest
<PAGE>

accrue hereunder based upon the Daily LIBOR shall be suspended until the Bank
shall notify the undersigned that the circumstances causing such suspension no
longer exist.

         In the event that on any date the Bank shall have reasonably determined
that accruing interest hereunder based upon the Daily LIBOR has become unlawful
by compliance by the Bank in good faith with any law, governmental rule,
regulation or order, then, and in any such event, the Bank shall promptly give
notice thereof to the undersigned. In such case, the ability of the undersigned
to request that interest accrue hereunder based upon the Daily LIBOR shall be
terminated and, when required by law, interest will accrue hereunder based upon
the Prime Commercial Rate.

         If, due to (1) the introduction of or any change in or in the
interpretation of any law or regulation, (2) the compliance with any guideline
or request from any central bank or other public authority (whether or not
having the force of law), or (3) the failure of the undersigned to pay any
amount when required by the terms of this Note, there shall be any loss or
increase in the cost to the Bank of accruing interest hereunder based upon the
Daily LIBOR, if applicable, then the undersigned agree that the undersigned
shall, from time to time, upon demand by the Bank, pay to the Bank additional
amounts sufficient to compensate the Bank for such loss or increased cost. A
certificate as to the amount of such loss or increase cost, submitted to the
undersigned by the Bank, shall be conclusive evidence, absent manifest error, of
the correctness of such amount.

MANNER OF PAYMENT
-----------------

         The Principal Sum shall be due and payable on April 30, 2002, and at
maturity, whether by demand, acceleration or otherwise. Accrued interest shall
be due and payable monthly beginning on May 15, 2000, and continuing on the 15th
day of each month thereafter, and at maturity, whether by demand, acceleration
or otherwise.

LATE CHARGE
-----------

         Any installment or other payment not made within 10 days of the date
such payment or installment is due shall be subject to a late charge equal to 5%
of the amount of the installment or payment.

SECURITY
--------

         This Note is secured by the security interests, assignments, and
mortgages granted and/or referenced in the Loan Agreement and by the security
interests, assignments, and mortgages granted pursuant to one or more collateral
security documents executed and delivered to the Bank after October 22, 1999.

DEFAULT
-------

         Upon the occurrence of any of the following events:
<PAGE>

                  (a) the undersigned fails to make any payment of interest or
         of the Principal Sum on or before the date such payment is due;

                  (b) an "Event of Default" under the Loan Agreement shall have
         occurred;

then the Bank may, at its option, without notice or demand, accelerate the
maturity of the obligations evidenced hereby, which obligations shall become
immediately due and payable. In the event the Bank shall institute any action
for the enforcement or collection of the obligations evidenced hereby, the
undersigned agrees to pay all costs and expenses of such action, including
reasonable attorneys' fees, to the extent permitted by law.

GENERAL PROVISIONS
------------------

         The undersigned, and any indorser, surety, or guarantor, hereby
severally waive presentment, notice of dishonor, protest, notice of protest, and
diligence in bringing suit against any party hereto, and consent that, without
discharging any of them, the time of payment may be extended an unlimited number
of times before or after maturity without notice. The Bank shall not be required
to pursue any party hereto, including any guarantor, or to exercise any rights
against any collateral herefor before exercising any other such rights.

         No waiver of any term or condition of this Note shall be effective
unless in writing and signed by the party giving or granting the waiver. No
amendment of any term or condition of this Note shall be effective unless in
writing and signed by the undersigned and the Bank. No failure or delay on the
part of the Bank in exercising any right, power or privilege under this Note,
related loan documents or law, nor any course of dealing, shall operate as a
waiver of any such right, power or privilege or preclude any other or further
exercise thereof or of any other right, power or privilege.

         The undersigned agrees that, to the extent that the undersigned makes a
payment or payments to the Bank, or the Bank receives any proceeds of collateral
security, which payment or payments or proceeds or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
and/or required to be repaid to any of the undersigned, its estate, trustee,
receiver or any other party, including without limitation any guarantor, under
any bankruptcy or insolvency law, or under any other state or federal law,
common law or equitable cause, then to the extent of such payment or repayment,
the obligations under this Note, or the part thereof which has been paid,
reduced or satisfied by such amount, shall be reinstated and continued in full
force and effect as of the date such initial payment, reduction or satisfaction
occurred.

         The obligations evidenced hereby may from time to time be evidenced by
another note or notes given in substitution, renewal or extension hereof. Any
security interest or mortgage which secures the obligations evidenced hereby
shall remain in full force and effect notwithstanding any such substitution,
renewal, or extension.

prosperity of the State and one or more of its political subdivisions, and will
promote the general welfare of the State's citizens.

          C.   Pursuant to the Act the actions authorized by the Issuing
Authority have been submitted by resolution to the Governor and Council; and
such recommendation from the Issuing Authority as to the passage of said
resolution, after a hearing, has been confirmed by the Governor and the Council;

and use of the facility to manufacture products for the telecommunications
industry, will serve a public purpose and provide a public benefit; and the
Governor and the Council have determined that the Issuer's financing of the
Project will be within the policy of, and the authority conferred by, the Act.

accompanied by evidence satisfactory to the Trustee and the Letter of Credit
Bank that the average reasonably expected economic life of the facilities being
financed by the Series 1999 Bonds is not less than 5/6ths of the average
maturity of the Series 1999 Bonds or, if such evidence is not presented with the
disbursement or at the request of the Trustee or the Letter of Credit Bank, by
an opinion of Bond Counsel to the effect that such disbursement will not result
in the interest on the Series 1999 Bonds becoming subject to Federal income
taxation.  In case any contract provides for the retention by the Borrower of a
portion of the contract price, there shall be paid from the Project Fund only
the net amount remaining after deduction of any such portion, and only when that
retained amount is due and payable, may it be paid from the Project Fund.

payment, or provision for payment, in full of the Project Costs, at the

                    (ii)  used to acquire, construct, install, equip and improve
          such additional real or personal property in connection with the
          Project as is designated by the Authorized Borrower Representative and
          approved by the Letter of Credit Bank and the acquisition,
          construction, installation, renovation, equipping and improvement of
          which will be permitted under the Act, provided that any such use
          shall be accompanied by evidence satisfactory to the Trustee that the
          average reasonably expected economic life of such additional property,
          together with the other property theretofore acquired with the
          proceeds of the Series 1999 Bonds, will not be less than 5/6ths of the
          average maturity of the Series 1999 Bonds or, if such evidence is not
          presented with the direction, then an opinion of Bond Counsel to the
          effect that the acquisition of such additional property will not
          result in the interest on the Series 1999 Bonds becoming included in
          gross income for federal income tax purposes;

                    (iii) used for the purchase of Series 1999 Bonds in the open
          market for the purpose of cancellation; or

                                       11
<PAGE>

                        (iv) used to accomplish a combination of the foregoing
          as is provided in that direction.

Any payments made pursuant to this paragraph shall be made only to the extent
that such use or application will not, in the opinion of Bond Counsel or under
rulings of the Internal Revenue Service, result in the interest on the
Segregated Series 1999 Bonds becoming included in gross income for federal
income tax purposes.

          and other similar governmental regulations,

                        (d)  that except as provided in subsection (e) of this
          Section, all costs of that acquisition, construction, installation,
          renovation, equipping and improvement then or theretofore due and
          payable have been paid, and

                        (e)  the amounts which the Trustee shall retain in the

          Section 3.7.  Investment of Fund Moneys. At the oral (to be promptly
                        -------------------------
confirmed in writing) or written request of the Authorized Borrower
Representative, any moneys held as part of the Bond Fund or the Project Fund
shall be invested or reinvested by the Trustee in Eligible Investments in
accordance with Section 5.05 of the Indenture. The Borrower hereby covenants
that the Borrower will restrict that investment and reinvestment and the use of
the proceeds of the Series 1999 Bonds in such manner and to such extent, if any,
as may be necessary so that the Series 1999 Bonds will not constitute arbitrage
bonds under Section 148 of the Code. If at any time and from time to time the
Borrower determines that it is necessary to restrict or limit the yield on the
investment of moneys held by the Trustee under the Indenture in order to prevent
the Series 1999 Bonds from becoming arbitrage bonds within the meaning of
Section 148 of the Code, the Borrower shall so instruct the Trustee in writing.

                        --------------------------------
conditions of this Agreement, the Issuer will make the Loan to the Borrower.  In
consideration of and in repayment of the Loan, the Borrower shall make as Loan
Payments, payments sufficient in time and amount to pay when due all Bond
Service Charges, all as more particularly provided in the Project Note and any
Additional Notes.  All such Loan Payments shall be paid to the Trustee in
accordance with the terms of the Notes for the account of the Issuer and shall
be held and applied in accordance with the provisions of the Indenture and this
Agreement.

          The Borrower shall, simultaneously with the delivery of the Series
1999 Bonds and the Project Note, deliver or cause to be delivered the Letter of
Credit to the Trustee.  Subject to the provisions of Section 5.09 of the
Indenture, the Borrower agrees that it will not, either by its action or
inaction, in any way adversely affect the continuance or effectiveness of the
Letter of Credit.

          In connection with the issuance of any Additional Bonds, the Borrower
shall execute and deliver to the Trustee one or more Additional Notes in a form
substantially similar to the form of the Project Note.  All such Additional
Notes shall:

                    (a) provide for payments of interest equal to the payments
          of interest on the corresponding Additional Bonds;

                    (b) require payments of principal and redemption payments
          and any premium equal to the payments of principal, prepayments and
          sinking fund payments and any premium on the corresponding Additional
          Bonds;

                    (c) require all payments on any such Additional Notes to be
          made no later than the due dates for the corresponding payments to be
          made on the corresponding Additional Bonds; and

                    (d) contain by reference or otherwise optional and mandatory
          redemption provisions and provisions in respect of the optional and
          mandatory acceleration or prepayment of principal and any premium
          corresponding with the redemption and acceleration provisions of the
          corresponding Additional Bonds.

          The Notes shall secure equally and ratably all outstanding Bonds,
except that, so long as no Event of Default described in paragraph (a), (b),
(c), (g), (h) or (i) of Section 7.01 of the Indenture has occurred and is
subsisting, payments by the Borrower on the Notes shall be used by the Trustee
to reimburse the Letter of Credit Bank for payment of Bond Service Charges on
the corresponding Bonds in connection with which the Note was delivered and
shall constitute Loan Payments made in respect of the related Bonds.

          Upon payment in full, in accordance with the Indenture, of the Bond
Service Charges, whether at maturity or by redemption or otherwise, or upon
provision for the payment thereof having been made in accordance with the
provisions of the Indenture, the Notes issued concurrently with those
corresponding Bonds, of the same maturity, bearing the same interest rate and in
an amount equal to the aggregate principal amount of the Bonds so surrendered
and cancelled or for the payment of which provision has been made, shall be
deemed fully paid, the obligations of the Borrower thereunder shall be
terminated, and such Notes shall be surrendered by the Trustee to the Borrower,
and shall be cancelled by the Borrower.  Unless the Borrower is entitled to a
credit under express terms of this Agreement or the Notes, all payments on the
Notes shall be in the full amount required thereunder.

          Except for such interest of the Borrower and the Letter of Credit Bank
as may hereafter arise pursuant to Section 8.5 hereof or Sections 5.04, 5.07 and
5.08 of the Indenture, and except as otherwise provided herein or in the
Indenture, the Letter of Credit Bank, by the issuance of the Letter of Credit,
the Borrower and the Issuer each acknowledge that neither the Borrower, the
Letter of Credit Bank nor the Issuer has any interest in the Bond Fund and any
moneys deposited therein shall be in the custody of and held by the Trustee in
trust for the benefit of the Holders.

Issuer in connection with the issuance and carrying of the Series 1999 Bonds and
all expenses reasonably incurred or advances reasonably made in the exercise of
the Issuer's rights or the performance of its obligations under the Bond
Documents.  Any fees, expenses, reimbursements or other charges which the Issuer
may be entitled to receive from the Borrower thereunder, if not paid when due,
shall bear a late charge equal to 5% of the amount overdue, and if not paid
within sixty (60) days, shall bear interest at twelve percent (12%) per annum.

          The Borrower shall pay to the Trustee, the Registrar and any Paying
Agent or Authenticating Agent their reasonable fees, charges and expenses for
acting as such under the Indenture, to the Remarketing Agent its reasonable
fees, charges and expenses for acting as such under the Remarketing Agreement
and to the Placement Agent its reasonable fees, charges and expenses for acting
as such under the Placement Agreement.

          Section 4.3.  Place of Payments.  The Borrower shall make all Loan
                        -----------------

payments to the Issuer, shall be unconditional and shall be binding and
enforceable in all circumstances whatsoever as provided in the Act and shall not
be subject to setoff, recoupment or counterclaim. The Borrower shall be
obligated to make the payments whether or not the Project has come into
existence or become functional and whether or not the Project has ceased to
exist or to be functional to any extent and from any cause whatsoever. The
Borrower shall be obligated to make such payments regardless of whether the
Borrower is in possession or is entitled to be in possession of the Project or
any part thereof.

          Section 4.5.  Assignment of Agreement and Revenues.  To secure the
                        ------------------------------------

Indenture, its rights under and interest in this Agreement (except for the
Unassigned Issuer's Rights) and the Revenues.  The Borrower hereby agrees and
consents to those assignments.

          Section 4.6.  Payments to Remarketing Agent.  The Borrower shall pay
                        -----------------------------
to the Remarketing Agent, on or before each Interest Payment Date, an amount

Series 1999 Bonds on such Interest Payment Date, pursuant to the Indenture,
provided that amounts available on such Interest Payment Date for such payment
from either (i) proceeds of the remarketing of such Series 1999 Bonds by the
Remarketing Agent or (ii) proceeds of a draw under the Letter of Credit shall be
credited against the Borrower's obligation to make payments under this Section.

          The Borrower hereby consents to the appointment of the Remarketing
Agent pursuant to and as specified in the Indenture.

          Section 4.7.  Letter of Credit. Simultaneously with the initial

Credit.  The Letter of Credit may be replaced by an Alternate Letter of Credit
complying with the provisions of Section 5.09 of the Indenture and shall be in
substantially the form of Exhibit A attached to the Letter of Credit Agreement
and made a part thereof.

          The Borrower hereby authorizes the Trustee to make drawings on the
Letter of Credit in accordance with its terms.

          Section 5.1.  Indemnification
                        ---------------

     (a.) The Issuer.   The Borrower, regardless of any agreement to maintain
          ----------
insurance, will indemnify the Issuer against (a) any and all claims by any
person related to the participation of the Issuer, the Trustee or the
Bondholders in the transactions contemplated by the Bond Documents, including
without limitation claims arising out of any condition of the Project or the
construction, use, occupancy or management thereof; any accident, injury or
damage to any person occurring in or about the Project Facilities; any breach by
the Borrower of its obligations under the Bond Documents; any act or omission of
the Borrower or any of its agents, contractors, servants, employees or
licensees; or the offering, issuance, sale or any resale of the Bonds to the
extent permitted by law, and (b) all costs, counsel fees, expenses or
liabilities reasonably incurred in connection with any such claim or any action
or proceeding brought thereon.  In case any action or proceeding is brought
against the Issuer by reason of any such claim, the Borrower will defend the
same at its expense upon notice from the affected person, and such person will
cooperate with the Borrower, at the expense of the Borrower, in connection
therewith.

     (b.) The Trustee.  The Borrower releases the Trustee from, agrees that the
          -----------
Trustee shall not be liable for, and agrees to protect, defend, indemnify and
hold harmless the Trustee from and against, any loss or damage to property, or
any injury to or death of any person, that may be occasioned by any cause
whatsoever pertaining to the Project Facilities or the use thereof; provided,
however, that the indemnity in this sentence shall be effective only to the
extent of any loss in excess of amounts paid to the Trustee from any liability
or property insurance carried with respect to the loss sustained.  The Borrower
further agrees to protect, defend, indemnify and hold harmless the Trustee
against and from any and all costs, liabilities, expenses and claims arising
from any breach or default on the part of the Borrower in the performance of any
covenant or agreement on the part of the Borrower to be performed pursuant to
the terms of any of the Bond Documents, or in connection with the issuance of
the Bonds and the Borrower's furnishing of information concerning the Project,
the Borrower, its financial status or other matters relating to the Borrower, or
arising from any act or failure to act by the Borrower or any of the Borrower's
agents, contractors, servants, employees, or licensees, or arising from any
accident, injury or damage whatsoever caused to any person, firm or corporation
occurring during the term of this Agreement, in or about the Project Facilities,
and from and against all costs, liabilities and expenses incurred in or in
connection with any claim, action or proceeding brought thereon.  In case any
action or proceeding is brought against the Trustee by reason of any such claim,
the Borrower upon notice from the Trustee covenants to resist or defend such
action or proceeding at the Borrower's expense.  The Trustee shall not settle or
compromise such claim, action or proceeding without the written consent of the
Borrower, if there exists no Event of Default by the Borrower as defined in
Section 7.1 hereof.  Nothing contained in this Section, however, shall require
the Borrower to indemnify the Trustee or any of its officers, employees or
agents, from any cost, liability, expense, loss or claim arising out of or
resulting from or the willful misconduct or negligence of the Trustee or any of
its officers, employees, independent contractors and agents.  The
indemnification provided by this

--------
its corporate existence and good standing and qualification to do business in
the State, and (ii) will not dispose of or transfer all or substantially all of
the Borrower's assets or the Project; provided, however, the Borrower may, with
the prior written consent of the Letter of Credit Bank and the Issuer, which the
Letter of Credit Bank and the Issuer shall have no obligation to give, transfer
all or substantially all of the Borrower's assets, including the Project to a
corporation or other entity, but only on the condition that (a) the transferee
or the surviving or resulting entity (if other than the Borrower) shall
expressly assume and agree in writing to perform all of the Borrower's
obligations under the Bond Documents and (b) such transfer will not cause the
Project to be in nonconformance with the purposes or provisions of the Act or
the Code.

          The Borrower or any of the Borrower's transferees may enter into any
of the transactions described in the preceding paragraph only if in the opinion
of Bond Counsel consummation thereof (a) is not prohibited by the Act, (b) will
not adversely affect the validity of any Bonds to be outstanding after giving
effect to such transaction, or (c) will not adversely affect the exempt status
of the interest on such Bonds under the Code.

          If a transfer of assets is made as provided in this Section, the
provisions of this Section shall continue in full force and effect and no
further such transfer of assets shall be made except in compliance  with the
provisions of this Section.

          Within 10 days after any transfer of assets under this Section, the
transferee or surviving or resulting entity shall provide written notice of such
event to the Issuer, the Letter of Credit Bank and the Trustee and evidence
satisfactory to the Issuer, the Letter of Credit Bank and the Trustee that all
requirements of this Section have been satisfied.

          Section 5.3.  Assignment by Issuer.  Except for the assignment of this
                        --------------------
Agreement to the Trustee, the Issuer shall not attempt to further assign,
transfer or convey its interest in the Project Facilities or this Agreement or
create any pledge or lien of any form or nature with respect to the Project
Facilities or the payments hereunder, except in its governmental capacity
incident to collection of taxes, assessments or other governmental charges.

          Section 5.4.  Reference to Bonds Ineffective After Bonds Paid.  Upon
                        -----------------------------------------------
Payment in Full of the Bonds, all references in this Agreement to the Bonds and
the Trustee shall be ineffective and neither the Issuer, the Trustee nor any
Bondholder shall thereafter have any rights hereunder, and the Borrower shall
have no further obligation hereunder, except for any obligation to the Issuer,
the Trustee, the Letter of Credit Bank or any Bondholder that shall have
theretofore vested and that shall then remain unsatisfied.

          Section 5.5.  Borrower's Performance under Indenture.  The Borrower
                        --------------------------------------

be bound by its terms.  The Borrower shall, for the benefit of the Issuer and
each Bondholder, do and perform all acts and things required or contemplated in
the Indenture to be done or performed by it,

                                       18

including without limitation the obligations of the Borrower with respect to
insurance, taxes and other charges and maintenance, modification, repairs and
restoration of the Project Facilities.

          Section 5.6.  Borrower Not to Adversely Affect Tax-Exempt Status of
                        -----------------------------------------------------
Interest on Series 1999 Bonds.  Notwithstanding anything herein to the
-----------------------------
contrary, the Borrower, for the benefit of the Issuer and each Bondholder,
hereby agrees that it will not take or permit to be taken on its behalf, any
action which would adversely affect the exclusion from gross income for federal
income tax purposes of the interest on the Series 1999 Bonds, and that it will
make and take, or require to be made and taken, such acts and filings as may
from time to time be required under the Code and pursuant to the Indenture to
establish and maintain the exclusion from gross income for federal income tax
purposes of the interest on the Series 1999 Bonds.

          Section 5.7.  Compliance with Laws.  The Borrower shall, throughout
                        --------------------
the term of this Agreement, promptly comply or cause compliance with all laws,
ordinances, orders, rules, regulations and requirements of duly constituted
public authorities which may be applicable to the Project Facilities or to the
repair and alteration thereof, or to the use or manner of use of the Project
Facilities, or to the Borrower's and any lessee's operations on the Project
Site.  Notwithstanding the foregoing, the Borrower shall have the right to
contest the legality or the applicability of any such law, ordinance, order,
rule, regulation or requirement so long as in the opinion of counsel
satisfactory to the Trustee and the Letter of Credit Bank such contest shall not
in any way materially adversely affect or impair the obligations of the Borrower
hereunder or any right or interest of the Trustee or the Letter of Credit Bank
in, to and under the Indenture or this Agreement.

          Section 5.8.  Taxes, Permits, Utility and Other Charges.  The Borrower
                        -----------------------------------------
shall pay and discharge, promptly as and when the same shall become due and
payable, all taxes and governmental charges of any kind whatsoever that may be
lawfully assessed against the Issuer, the Trustee, the Letter of Credit Bank or
the Borrower with respect to the Project or Project Site or any portion thereof.
Subject to the provisions of the Security Agreement, the Borrower may in good
faith contest any such tax or governmental charge, and in such event may permit
such tax or governmental charge to remain unsatisfied during the period of such
contest and any appeal therefrom unless in the opinion of counsel satisfactory
to the Trustee and the Letter of Credit Bank by such action any right or
interest of the Trustee or the Letter of Credit Bank in, to and under the
Indenture or this Agreement shall be materially endangered or the Project or
Project Site or any part thereof shall become subject to imminent loss or
forfeiture, in which event such tax or governmental charge shall be paid prior
to any such loss or forfeiture.  The Borrower shall procure or cause to be
procured any and all necessary building permits, other permits, licenses and
other authorizations required for the lawful and proper construction,
installation, renovation, equipping, use and operation of the Project.

          Section 5.9.  Right of Access.  The Borrower agrees that, subject to
                        ---------------
reasonable security and safety regulations, the Issuer, the Trustee and the
Letter of Credit Bank and their or any of their duly authorized agents shall
have the right during normal business hours to inspect any records with respect
to the Project and to enter upon the Project Site for purposes of Project
inspection.  The Borrower further agrees that the Issuer, the Trustee and the
Letter of Credit Bank and their duly authorized agents shall have such rights of
access to the Project as may be reasonably necessary to cause to be completed
the acquisition, construction, installation,

                                       19

renovation and equipping provided for herein, and thereafter for the proper
maintenance of the Project in the event of failure by the Borrower to perform
the Borrower's obligations hereunder.

          Section 5.10. Litigation Notice.  The Borrower shall give the
                        -----------------
Trustee, the Original Purchaser and the Letter of Credit Bank prompt notice of
any action, suit or proceeding by the Borrower or against the Borrower at law or
in equity, or before any governmental instrumentality or agency, or of any of
the same which may be threatened, which if adversely determined, would
materially impair the right of the Borrower to carry on the business which is
contemplated in connection with the Project, or would materially and adversely
affect the Borrower's business, operations, properties, assets or condition.

          Section 5.11. Removal of Portions of the Project.  The Borrower shall
                        ----------------------------------
be under no obligation to renew, repair or replace any inadequate, obsolete,
worn out, unsuitable, undesirable or unnecessary portions of the Project;
provided, however, that such failure to renew, repair or replace does not impair
the character of the Project as a "project" within the meaning of the Act.
Subject to the Security Agreement, the Borrower shall have the right, from time
to time, to substitute personal property for any portion of the Project,
provided that the property so substituted shall not impair the character of the
Project as a "project" within the meaning of the Act, and shall have a value not
less than the value of the personal property for which it is substituted.  Any
such substituted property shall be included under the terms of this Agreement as
part of the Project.

          The Borrower shall have the right to remove any portions of the
Project consisting of personal property, without substitution therefor;
provided, however that such removal does not impair the character of the Project
as a "project" within the meaning of the Act and so long as such removal does
not violate any terms of the Letter of Credit Agreement or the Security
Agreement.

on the Letter of Credit used for purchasing Series 1999 Bonds or for calling
Series 1999 Bonds for optional redemption in accordance with the applicable
provisions of the Indenture providing for optional redemption at the redemption
price stated in the Indenture.  Pending application for those purposes, any
moneys so delivered shall be held by the Trustee in a special account in the
Bond Fund and delivery of those moneys shall not operate to abate or postpone
Loan Payments or Additional Payments otherwise becoming due or to alter or
suspend any other obligations of the Borrower under this Agreement.

accordance with the applicable provisions of the Indenture upon the occurrence
of any of the following events:

     extent that (1) it cannot reasonably be expected to be restored, within a
     period of six months, to the condition thereof immediately preceding such
     damage or destruction or (2) its normal use and operation is reasonably
     expected to be prevented for a period of six consecutive months.

          (b)  Title to, or the temporary use of, all or a significant part
     of the Project shall have been taken under the exercise of the power of
     eminent domain (1) to such extent that the Project cannot reasonably be
     expected to be restored within a period of six months to a condition of
     usefulness comparable to that existing prior to the taking or (2) as a
     result of the taking, normal use and operation of the Project is reasonably
     expected to be prevented for a period of six consecutive months.

          (c)  As a result of any changes in the Constitution of the State,
     the Constitution of the United State of America, or state or Federal laws
     or as a result of legislative or administrative action (whether state or
     federal) or by final decree, judgment or order of any court or
     administrative body (whether state or federal) entered after the contest
     thereof by the Issuer or the Borrower in good faith, this Agreement shall
     have become void or unenforceable or impossible of performance in
     accordance with the intent and purpose of the parties as expressed in this
     Agreement, or if unreasonable burdens or excessive liabilities shall have
     been imposed with respect to the Project or the operation thereof,
     including, without limitation, Federal, state or other ad valorem,
     property, income or other taxes not being imposed on the date of this
     Agreement other than ad valorem taxes presently levied upon privately owned
     property used for the same general purpose as the Project.

To exercise that option, the Borrower shall, within 120 days following the event
authorizing the exercise of that option, give notice to the Issuer and to the
Trustee specifying the date on which the Borrower will deliver the funds
required for that redemption which date shall be not more than ninety days from
the date that notice is mailed and shall make arrangements satisfactory to the
Trustee for the giving of the required notice of redemption.  The foregoing
option may be exercised whether or not the Borrower is in default hereunder;
provided, that such default will not relieve the Borrower from performing those
actions which are necessary to exercise any such right or option granted
hereunder.

          The amount payable by the Borrower in the event of the Borrower's
exercise of the option granted in this Section shall be an amount of money
which, when added to the moneys and investments held to the credit of the Bond
Fund, will be sufficient pursuant to the provisions of the Indenture to pay, at
par, and discharge all then outstanding Series 1999 Bonds on the earliest
applicable redemption date.

          The Borrower also shall have the option, exercisable as provided above
in this Section, in the event that title to or the temporary use of a portion of
the Project shall be taken under the exercise of the power of eminent domain,
even if the taking is not of such nature as to permit the exercise of the
redemption option upon an event specified in (b) above, to direct the
redemption, at a redemption price of 100% of the principal amount thereof
prepaid, plus accrued interest to the redemption date, of that part of the
outstanding principal balance of the Series 1999 Bonds as may be payable from
the proceeds (after the payment of costs and expenses incurred in the collection
thereof) received in the eminent domain proceeding, provided, that the Borrower
shall furnish to the Issuer, the Trustee, and the Letter of Credit Bank a
certificate of an independent architect or engineer stating that (1) the
property comprising the part of the Project then being taken under the power of
eminent domain is not essential to continued operations of the Project in the
manner existing prior to that taking, (2) the Project has been restored to a
condition substantially equivalent to that existing prior to the taking, or (3)
other improvements have been acquired or made which are suitable for the
continued operation of the Project.

          The rights and option granted to the Borrower in this Section may be
exercised whether or not the Borrower is in default hereunder; provided, that
such default will not relieve the Borrower from performing those actions which
are necessary to exercise any such right or option granted hereunder.

          Section 6.3.  Mandatory Redemption in Event of Loss of Tax Exemption

---------------------------------
the Indenture, Series 1999 Bonds become subject to mandatory redemption as a
result of a Determination of Taxability, as defined in the Indenture, or the
Borrower fails to obtain not less than 60 days prior to the Interest Payment
Date next preceding a Letter of Credit Termination Date an extension of the
Letter of Credit or to provide for the delivery to the Trustee of an Alternate
Letter of Credit on the terms provided in the Indenture, the Borrower shall
deliver to the Trustee, upon the date required by the Trustee, moneys sufficient
to pay in full such Series 1999 Bonds in accordance with the mandatory
redemption provisions relating thereto set forth in the Series 1999 Bonds and
the Indenture.

                        -----------------
the Trustee, the Issuer shall take all steps required of it under the applicable
provisions of the Indenture or the Series 1999 Bonds to effect the redemption of
all or a portion of the Series 1999 Bonds pursuant to this Article VI.

          Section 6.6.  Required Deposits for Optional Redemption.  All
                        -----------------------------------------
redemptions of Series 1999 Bonds provided for in Article VI hereof and in
Article IV of the Indenture shall be accomplished through the exercise by the
Trustee of draws on the Letter of Credit Bank under the Letter of Credit.
Except with the prior written consent of the Letter of Credit Bank, the Trustee
shall not give notice of call pursuant to the optional redemption provisions of
Section 4.01(d) and (e) of the Indenture and Article VI hereof unless prior to
the date by which the call notice is to be given there shall be deposited by the
Borrower with the Trustee Eligible Funds which, in addition to any other moneys
available therefor and held by the Trustee, will be sufficient to redeem at the
redemption price thereof, including premium, if any, and interest accrued to the
redemption date, all of the redeemable Series 1999 Bonds for which notice of
redemption is to be given in accordance with the provisions of the Indenture.

          All amounts paid by the Borrower pursuant to this Article which are
used to pay principal of, premium, if any, or interest on the Series 1999 Bonds,
or to reimburse the Letter of Credit Bank for moneys drawn on the Letter of
Credit and used for such purposes, shall constitute prepaid Loan Payments.

          Section 7.1.   Events of Default.  Each of the following events is
                         -----------------
hereby declared an Event of Default:

          (a)     The Borrower's failure to make any payment of Loan Payments or
          Additional Payments or any payment under Article VI hereof within the
          time required herein.

          (b)     The occurrence of an event of default under the Security
          Agreement, the Letter of Credit Agreement or the Indenture.

          (c)     The Borrower's failure to observe and perform any of its other
          covenants, conditions or agreements contained herein for a period of
          30 days after written notice (unless the Issuer, the Letter of Credit
          Bank and the Trustee shall agree in writing to an extension of such
          time prior to its expiration) specifying such failure and requesting
          that it be remedied, given by the Issuer, the Letter of Credit Bank or
          the Trustee to the Borrower; provided however that if such failure
          shall be such that it can be corrected but not within such period, it
          shall not constitute an Event of Default if corrective action is
          promptly instituted by the Borrower within such period and diligently
          and continuously pursued until the failure is corrected; provided,
          further, in no event shall such additional period exceed 30 additional
          days.

          (d)     If any representation or warranty by the Borrower contained
          herein, or in the Security Agreement or the Bond Placement Agreement,
          or in any certificate or instrument delivered by the Borrower pursuant
          hereto or thereto, is false or misleading in any material respect.

          (e)     The transfer of the assets of the Borrower, except as may be
          permitted herein.

          (f)     The Borrower shall commence any case, proceeding or other
          action relating to the Borrower in bankruptcy or seeking
          reorganization, liquidation, dissolution, winding-up, arrangement,
          composition, readjustment of the Borrower's debts, or for any other
          relief, under any bankruptcy, insolvency, reorganization, liquidation,
          dissolution, arrangement, composition, readjustment of debt or other
          similar act or law of any jurisdiction, now or hereafter existing; or
          the Borrower shall apply for a receiver, custodian or trustee of the
          Borrower or for all or a substantial part of the Borrower's property;
          or the Borrower shall make an assignment for the benefit of creditors;
          or the Borrower shall be unable to, or shall admit in writing the
          inability to, pay the Borrower's debts as they become due; or the
          Borrower shall take any action indicating the Borrower's consent to,
          approval of or acquiescence in, or in the furtherance of, any of the
          foregoing.

          (g)     Any case, proceeding or other action against the Borrower
          shall be commenced in bankruptcy or seeking reorganization,
          liquidation, dissolution, winding-up, arrangement, composition or
          readjustment of the Borrower's debts, or any other relief, under any
          bankruptcy, insolvency, reorganization, liquidation, dissolution,
          arrangement, composition, readjustment of debt or other similar act or
          law of any jurisdiction, now or hereafter existing; or a receiver,
          custodian or trustee of the Borrower or for all or a substantial part
          of the Borrower's property shall be appointed; or a warrant of
          attachment, execution or restraint, or similar process shall be issued
          against any substantial part of the property of the Borrower; and in
          each such case such condition shall continue for a period of 60 days
          undismissed, undischarged or unbonded.

          The provisions of paragraph (c) of this Section are subject to the
following limitations: If by reason of acts of God; winds; fires; epidemics;
landslides; floods; droughts; famines; strikes; lockouts or other industrial
disturbances; acts of public enemies; acts or orders of any kind of any
governmental authority; insurrection; military action; war, whether or not
declared; sabotage; riots; civil disturbances; explosions; breakage or accident
to transmission pipes or canals; partial or entire failure of utilities; or any
cause or event not reasonably within the control of Borrower, Borrower is unable
in whole or in part to carry out the agreements on Borrower's part herein
contained, other than obligations on the part of Borrower to make the payments
required under the Notes, the Agreement and the Letter of Credit Agreement, to
carry insurance, to pay any ad valorem property taxes, and to make other
payments or deposits pursuant to the terms hereof, Borrower shall not be deemed
in default during the continuance of such inability. Borrower shall, however,
use Borrower's best efforts to remedy with all reasonable dispatch the cause or
causes preventing Borrower from carrying out Borrower's agreements; provided,
that Borrower shall not in any event be required to settle strikes, lockouts or
other industrial disturbances by acceding to the demands of the opposing party
or parties when such course is, in the judgment of Borrower, not in the interest
of Borrower.

          The provisions of paragraphs (f) and (g) of this Section are subject
to the condition that the declaration of an Event of Default due to any of the
acts or circumstances specified therein, and the exercise of remedies upon any
such declaration, shall be subject to any applicable limitations of the United
States Bankruptcy Code affecting or precluding such declaration or exercise
during the pendency of or immediately following any bankruptcy, liquidation or
reorganization proceedings.

          Section 7.2.   Remedies on Default.  Whenever any Event of Default
                         -------------------
shall have happened and be continuing, any one or more of the following rights
and remedies may be exercised:

          (a)     If acceleration of the Bonds has occurred pursuant to Section
          7.03 of the Indenture, the Trustee may declare all Loan Payments to be
          immediately due and payable, whereupon the same shall become
          immediately due and payable. If the Trustee elects to exercise the
          remedy afforded in this Section 7.2(a) and accelerates all Loan
          Payments, the amount then due and payable by the Borrower as
          accelerated payments shall be the sum of (1) the aggregate principal
          amount of the Bonds then outstanding, (2) all unpaid interest on the
          Bonds accruing to the

                                       25
<PAGE>

          date set pursuant to the Indenture, (3) the amount of the redemption
          premium, if any, then applicable to the Bonds, (4) all unpaid Trustee,
          Registrar, Authenticating Agents, Remarketing Agent and Paying Agent
          fees and expenses accruing to such date, and (5) any amount then due
          the Issuer hereunder.

          (b)     The Trustee may have access to and inspect, examine and make
          copies of, the financial books, records and accounts of the Borrower
          pertaining to the Project Facilities.

          (c)     The Trustee may exercise any remedy provided for in the
          Indenture.

          (d)     The Trustee may take whatever action at law or in equity may
          appear necessary or desirable to collect any sums then due and
          thereafter to become due hereunder or to enforce the observance or
          performance of any covenant, condition or agreement of the Borrower
          hereunder.

          Except in the case of an Event of Default pursuant to Section 7.01(g)
or (h) of the Indenture, the Letter of Credit Bank shall have the right to
direct the remedies to be exercised by the Trustee.

          The Trustee shall promptly notify the Letter of Credit Bank of any
failure of the Borrower to make the Loan Payments required by Section 4.1
hereof.

          Any amounts collected pursuant to action taken by the Trustee under
this Section shall be paid into the Bond Fund and applied in accordance with the
provisions of the Indenture.

          Notwithstanding any contrary provision in the Bond Documents, the
Issuer shall have the right to take any action or make any decision with respect
to proceedings for indemnity against the liability of the Issuer and for
collection or reimbursement from sources other than moneys or property held
under the Bond Documents. Whenever any Event of Default shall have occurred and
be continuing which results from failure of the Borrower to pay to or perform
for the Issuer any payment, covenant, agreement or warranty not assigned to the
Trustee, the Issuer may (but need not) proceed directly against the Borrower and
may take any action at law or in equity which it may deem necessary or desirable
to collect or enforce such payment or performance in default. The Issuer shall
promptly notify the Trustee and the Letter of Credit Bank of any such action;
however, the failure of the Issuer to give such notice shall not affect the
validity of any such action.

          The provisions of this Section are subject to the further limitation
that the rescission by the Trustee of its declaration that all of the Bonds are
immediately due and payable also shall constitute an annulment of any
corresponding declaration made pursuant to paragraph (a) of this Section and a
waiver and rescission of the consequences of that declaration and of the Event
of Default with respect to which that declaration has been made, provided that
no such waiver or rescission shall extend to or affect any subsequent or other
default or impair any right consequent thereon. Unless the Letter of Credit Bank
is in default pursuant to Section 7.01(g) or (h) of the Indenture, any
rescission of a declaration of acceleration shall be subject to the prior
written consent of the Letter of Credit Bank.

          Section 7.3.   No Remedy Exclusive.  No remedy herein conferred upon
                         -------------------
or reserved to the Trustee is intended to be exclusive of any other remedy, and
every remedy shall be cumulative and in addition to every other remedy herein
and in the Indenture or now or hereafter existing at law, in equity or by
statute. No delay or omission to exercise any right or power accruing upon an
Event of Default shall impair any such right or power or shall be construed to
be a waiver thereof, but any such right or power may be exercised from time to
time and as often as may be deemed expedient. In order to enable the Issuer or
the Trustee to exercise any remedy reserved to it herein, it shall not be
necessary to give any notice, other than such notice as may be expressly
required herein.

          Section 7.4.   Agreement to Pay Attorney's Fees and Expenses.  If an
                         ---------------------------------------------
Event of Default should occur and the Issuer or the Trustee should incur
expenses, including attorneys' fees, in connection with the enforcement of this
Agreement, the Indenture, the Bond Placement Agreement or the Notes or the
collection of sums due thereunder, the Borrower shall reimburse the Issuer and
the Trustee, as applicable, for the expenses so incurred upon demand. If any
such expenses are not so reimbursed, the amount thereof, together with interest
thereon from the date of demand for payment at the Interest Rate for Advances,
and in any action brought to collect that indebtedness, the Trustee or the
Issuer, as applicable, shall be entitled to seek the recovery of those expenses
in such action except as limited by law or by judicial order or decision entered
in such proceedings.

          Section 7.5.   Waiver of Events of Default.  If the Trustee shall
                         ---------------------------
rescind any declaration of acceleration of payments of the principal of and
interest on the Bonds, such rescission shall also waive any corresponding Event
of Default hereunder and its consequences. In case of any such waiver or
rescission, or in case any proceeding taken by the Issuer or Trustee on account
of any such Event of Default shall have been discontinued or abandoned or
determined adversely, then and in every such case the Issuer, the Borrower and
the Trustee shall be restored to their former positions and rights hereunder,
but no such waiver or rescission shall extend to any subsequent or other Event
of Default or impair any right consequent thereon.

          Section 7.6.   Remedies Subject to Provisions of Law.  All rights,
                         -------------------------------------
remedies and powers provided by this Article may be exercised only to the extent
that the exercise thereof does not violate any applicable provision of law, and
all the provisions of this Article are intended to be subject to all applicable
mandatory provisions of law which may be controlling, and to be limited to the
extent necessary so that they will not render this Agreement invalid or
unenforceable under the provisions of any applicable law.

          Section 7.7.   Remedies Under Uniform Commercial Code.  In addition to
                         --------------------------------------
any other remedies provided for hereby, the Issuer and the Trustee shall have
the rights of a secured party and the Borrower shall have the rights of a debtor
under the Uniform Commercial Code of the State with respect to this Agreement
upon the occurrence and continuance of an Event of Default hereunder.

on September 1, 2019, together with interest from the date hereof on the unpaid

          This Note has been executed and delivered by the Borrower to the
Trustee pursuant to a certain Loan Agreement (the "Agreement") dated as of
September 1, 1999, between the Business Finance Authority of the State of New
Hampshire (the "Issuer") and the Borrower.  Under the Agreement, the Issuer has

$3,500,000 Adjustable Rate Demand Industrial Development Revenue Bonds, Series
1999 (Apex Telecommunications Manufacturing, Inc. Project) dated as of the date
of their issuance (the "Series 1999 Bonds") to assist in the financing of the

Project, and the Borrower has agreed to repay such loan by making payments
("Loan Payments") at the times and in the amounts set forth in this Note for
application to the payment of the principal of and redemption premium, if any,
and interest on the Series 1999 Bonds as and when due, or as otherwise provided
in the Agreement.  The Series 1999 Bonds have been issued, concurrently with the
execution and delivery of this Note, pursuant to, and are secured by, the Trust
Indenture (the "Indenture"), dated as of September 1, 1999, between the Issuer
and the Trustee.  The Series 1999 Bonds bear interest from their date at the
applicable rate as provided in Appendix I to this Note, and mature on September
1, 2019.  Those words and terms not expressly defined herein or in Appendix I
hereto and used herein or in Appendix I with initial capitalization where rules
of grammar do not otherwise require capitalization, or which are otherwise
defined terms under the Agreement or the Indenture, shall have the means set

     Bonds due on September 1, 2019 by reason of maturity;

               (2)  on the last Business Day of each month commencing October,
     1999, the amount necessary, together with any moneys then on deposit with
     the Trustee and available for that purpose, to pay an amount equal to the
     interest payable on the Series 1999 Bonds on the next succeeding interest
     payment date.

In connection with the payment due on the date of issuance of the Series 1999
Bonds, the Borrower shall receive credit for the accrued interest, if any, on
the Series 1999 Bonds paid upon their delivery.  To the extent moneys on deposit
from time to time in the Bond Fund , other than moneys representing a draw on
the Letter of Credit, exceed the amount necessary to pay Bond Service Charges
next due on the Series 1999 Bonds and the Trustee's Ordinary Expenses  then due,
the Borrower shall receive a credit for such excess amounts against any payments
due hereunder.

          All Loan Payments shall be payable in lawful money of the United
States of America and shall be made to the Trustee at its principal corporate
trust office for the account of the Issuer and deposited in the Bond Fund
created by the Indenture.  Except as otherwise provided in the Indenture, such
Loan Payments shall be used by the Trustee to reimburse the Letter of Credit
Bank for drawings under the Letter of Credit.

          The obligation of the Borrower to make the payments required hereunder
shall be absolute and unconditional and the Borrower shall make such payments
without abatement, diminution or deduction regardless of any cause or
circumstances whatsoever including, without limitation, any defense, set-off,

          This Note is subject to optional, extraordinary optional and mandatory
prepayment upon the same terms and conditions, on the same date or dates and at
the same prepayment prices, as the Series 1999 Bonds are subject to optional,
extraordinary optional and mandatory redemption, and the Borrower hereby agrees
that the Borrower will make Loan Payments hereunder in an amount equal to the
principal of and premium, if any, and interest on the Series 1999 Bonds due and
payable on each such redemption date. Any such optional redemption prior to
stated maturity is subject to the obligation of the Borrower to give the Issuer
and the Trustee sufficient notice of such redemption and to deposit moneys
sufficient to effect such optional redemption pursuant to the terms of the
Indenture as shall enable the Issuer and the Trustee to take all action
necessary under the Indenture to redeem on the date specified for prepayment a
like principal amount of Series 1999 Bonds at the same redemption price.

          Whenever an event of default under Section 7.01 of the Indenture shall
have occurred and, as a result thereof, the principal of and any premium on all
Series 1999 Bonds then outstanding, and the interest accrued thereon, shall have
been declared to be immediately due and payable pursuant to Section 7.03 of the
Indenture, the unpaid principal amount of and any premium and accrued interest
on this Note shall also be due and payable on the date on which the principal of
and premium and interest on the Series 1999 Bonds shall have been declared due
and payable; provided that the annulment of a declaration of acceleration with
respect to the Series 1999 Bonds shall also constitute an annulment of any
corresponding declaration with respect to this Note.

          If an Event of Default  should occur and the Issuer or the Trustee
should incur expenses, including attorneys' fees, in connection with the
enforcement of this Note or the collection of sums due hereunder, the Borrower
shall reimburse the Issuer and the Trustee, as applicable, for the expenses so
incurred upon demand; provided that such attorneys' fees shall be allowed only
to the extent actually paid and shall not be allowed to a salaried employee of
the Issuer or the Trustee.
