ARTICLE I




4.95% Senior Notes due 2021



          SECTION 1.01 Establishment and Terms.



          There is hereby established a new Series of Securities to be issued under the Indenture, to be
designated as the Company’s 4.95% Senior Notes due 2021 (the “Notes”).



          The aggregate principal amount of Notes that may be authenticated and delivered under the
Indenture is unlimited. The Notes that are to be authenticated and delivered on the date hereof
(the “Initial Notes”) will be in an aggregate principal amount of $650,000,000.



          With respect to any additional Notes (the “Additional Notes”) the Company elects to issue
under the Indenture, the Company shall set forth in an Officers’ Certificate the following
information:




	 	(i)	 	the aggregate principal amount of such Additional Notes to be
authenticated and delivered pursuant to this Indenture; and
	 
	 	(ii)	 	the issue price and the issue date of such Additional Notes,
including the date from which interest shall accrue.





          For purposes of the Indenture, notes will not be deemed to be Additional Notes of a Series
unless the maturity date, interest payment dates, record dates and interest rate are identical to
the Initial Notes for that Series.



          The Initial Notes and any Additional Notes shall be considered collectively as a single class
for all purposes of the Indenture. Holders of the Initial Notes and any Additional Notes will vote
and consent together on all matters to which such Holders are entitled to vote or consent as one
class, and none of the Holders of the Initial Notes or any Additional Notes shall have the right to
vote or consent as a separate class on any matter to which such Holders are entitled to vote or
consent.



          The Notes shall each be issued in the form of one or more Global Securities in substantially
the form set out in Exhibit A. The initial Depositary with respect to the Notes shall be
The Depository Trust Company (“DTC”).



          SECTION 1.02 Maturity, Payment of Principal and Interest.



          The Notes will mature on February 15, 2021.



          The Notes will bear interest at the rate of 4.95% per annum. The interest payment dates with
respect to the Notes will be February 15 and August 15 of each year. The first interest payment
date with respect to the Initial Notes will be August 15, 2011. Interest payable on each February
15 and August 15 shall be paid to the Person in whose name the applicable Note is registered on the
immediately preceding February 1 and August 1, respectively. Interest on the



-2-









 







Initial Notes will accrue from February 7, 2011. Interest will be computed on the basis of a
360-day year of twelve 30-day months.



          All payments of principal, premium (if any) and interest on the Notes shall be made in
accordance with Section 4.1 of the Original Indenture and in the manner set forth in Section 2.13
of the Original Indenture and Exhibit A hereto.



          SECTION
1.03 No Sinking Fund or Payments of Additional Amounts.



          The Notes will not be subject to a sinking fund and no payments of Additional Amounts shall be
made on the Notes.



          SECTION
1.04 Optional Redemption.



          The Company may, at its option, redeem the Notes in whole at any time or in part from time to
time, on at least 30 but not more than 60 days’ prior notice, at a redemption price equal to the
greater of:




	 	(i)	 	100% of the principal amount of the Notes being redeemed, and
	 
	 	(ii)	 	the present value of the Remaining Scheduled Payments on the
Notes being redeemed on the redemption date, discounted to the date of
redemption, on a semiannual basis, at the Treasury Rate plus 25 basis points.





          If the Company elects to redeem the Notes pursuant to this Section 1.04, it shall also pay
accrued and unpaid interest, if any, to the date of redemption, subject to the rights of Holders on
the relevant record date to receive interest due on the relevant interest payment date.



          On or after November 15, 2020, the Notes will be redeemable, in whole or in part, at a
redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued
interest to the date of redemption.



          In determining the redemption price and accrued interest pursuant to this Section 1.04,
interest will be calculated on the basis of a 360-day year consisting of twelve 30-day months.



          For the purposes of this Section 1.04, the following definitions are applicable:



          “Comparable Treasury Issue” means, with respect to the Notes, the United States Treasury
security selected by the Reference Treasury Dealer as having a maturity comparable to the remaining
term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance
with customary financial practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of such Notes.



          “Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the
bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of
its principal amount) on the third Business Day preceding such redemption date, as set forth in the
daily statistical release (or any successor release) published by the Federal



-3-









 







Reserve Bank of New York and designated “Composite 3:30 p.m. Quotations for U.S. Government
Securities” or (2) if such release (or any successor release) is not published or does not contain
such price on such Business Day, (A) the average of the Reference Treasury Dealer Quotations for
such redemption date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (B) if the Trustee is given fewer than four such Reference Treasury Dealer
Quotations, the average of all such quotations.



          “Reference Treasury Dealer” means (A) Barclays Capital Inc., Merrill Lynch, Pierce, Fenner &
Smith Incorporated and a Primary Treasury Dealer (as defined herein) selected by Wells Fargo
Securities, LLC (or their respective affiliates which are Primary Treasury Dealers) and each of
their successors; provided, however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall
substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s)
selected by us.



          “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer
and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for
the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third
Business Day preceding such redemption date.



          “Remaining Scheduled Payments” means, with respect to any Notes, the remaining scheduled
payments of the principal thereof to be redeemed and interest thereon that would be due after the
related redemption date but for such redemption; provided, however, that, if such redemption date
is not an interest payment date with respect to such Note, the amount of the next succeeding
scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to
such redemption date.



          “Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the
semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for such redemption date.



          SECTION
1.05 Offer To Repurchase Upon Change Of Control Triggering Event.



          (a) Upon the occurrence of a Change of Control Triggering Event, unless the Company has
exercised its right to redeem the Notes pursuant to Section 1.04 of this Second Supplemental
Indenture, each Holder shall have the right to require the Company to repurchase all or any part
(equal to $2,000 and integral multiples of $1,000 in excess thereof) of such Holder’s Notes
pursuant to the offer described below (the “Change of Control Offer ”) at an offer price in cash
equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any,
to the date of purchase (the “Change of Control Payment ”), subject to the rights of Holders on the
relevant record date to receive interest due on the relevant interest payment date. Within 30 days
following the date upon which any Change of Control Triggering Event occurs, or at the Company’s
option, prior to any Change of Control Triggering Event but subject to the occurrence of a Change
of Control Triggering Event, the Company shall mail a notice to



-4-









 







each Holder describing the transaction or transactions that constitute the Change of Control
and offering to repurchase Notes on the date specified in such notice, which date shall be no
earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of
Control Payment Date”), pursuant to the procedures required by the Indenture and described in such
notice. The notice, if mailed prior to the occurrence of the Change of Control Triggering Event,
shall state that the Change of Control Offer is conditioned on the occurrence of a Change of
Control Triggering Event on or prior to the Change of Control Payment Date. The Company shall
comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder to the extent such laws and regulations are applicable in connection with
the repurchase of the Notes as a result of a Change of Control Triggering Event.



          (b) On the Change of Control Payment Date, the Company shall, to the extent lawful:



          (i) accept for payment all Notes or portions thereof properly tendered pursuant to the
Change of Control Offer and not withdrawn;



          (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in
respect of all Notes or portions thereof so tendered and not withdrawn; and



          (iii) deliver or cause to be delivered to the Trustee the Notes so accepted together
with an Officers’ Certificate stating the aggregate principal amount of Notes or portions
thereof being purchased by the Company.


The Paying Agent shall promptly transmit to each Holder of Notes so tendered the Change of Control
Payment for such Notes, and the Trustee shall promptly authenticate and transmit (or cause to be
transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased
portion of the Notes surrendered, if any; provided that each such new Note shall be in a principal
amount of $2,000 and integral multiples of $1,000 in excess thereof.



The Company will not be required to make a Change of Control Offer upon a Change of Control
Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and
otherwise in compliance with the requirements set forth in Article III of the Original Indenture
and this Section 1.05 applicable to a Change of Control Offer made by the Company and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.




          (c) For the purposes of this Section 1.05, the following definitions are applicable:



          “Change of Control” means the occurrence of any one of the following:



               (1) the sale, lease, transfer, conveyance or other disposition (other than by way of merger or
consolidation), in one or a series of related transactions, of all or substantially all of the
assets of the Company and its Subsidiaries taken as a whole to any person (as that term is used in
Section 13(d)(3) of the Exchange Act) other than to the Company or one of its Subsidiaries;



-5-









 





               (2) the consummation of any transaction (including without limitation, any merger or

more than 50% of the outstanding Voting Stock of the Company, measured by voting power rather than
number of shares, other than by a person whose outstanding Voting Stock, measured by voting power
rather than number of shares, is owned 100%, directly or indirectly, by Holdings;



               (3) the first day on which the majority of the members of the board of directors of the
Company cease to be Continuing Directors; or



               (4) the adoption of a plan relating to the liquidation or dissolution of the Company.



          “Change of Control Triggering Event” means the Notes cease to be rated Investment Grade by at
least two of the three Rating Agencies on any date during the 60-day period (the “Trigger Period”)
commencing on the earlier of (1) the occurrence of a Change of Control and (2) public notice of the
pending occurrence of a Change of Control or our intention to effect a Change of Control (which
Trigger Period will be extended for so long as any of the Rating Agencies has publicly announced
that it is considering a possible ratings change).



          Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have
occurred in connection with any particular Change of Control (1) if the Rating Agencies making the
reduction in rating that causes the Notes to cease to be rated Investment Grade do not announce or
publicly confirm or inform the Trustee in writing at its request that the reduction was the result,
in whole or in part, of any event or circumstance comprised of or arising as a result of, or in
respect of, the applicable Change of Control (whether or not the applicable Change of Control has
occurred at the time of the ratings reduction) and (2) unless and until such Change of Control has
actually been consummated.



          “Continuing Directors” means, as of any date of determination, any member of the board of
directors of the Company who (1) was a member of such board of directors on the date hereof; or (2)
was nominated for election or elected to such board of directors with the approval of a majority of
the Continuing Directors who were members of such board of directors at the time of such nomination
or election.



          “Fitch” means Fitch Inc., a subsidiary of Fimalac, S.A., and its successors.



          “Investment Grade” means a rating of BBB- or better by Fitch (or its equivalent under any
successor rating categories of Fitch); a rating of Baa3 or better by Moody’s (or its equivalent
under any successor rating categories of Moody’s); and a rating of BBB- or better by S&P (or its
equivalent under any successor rating categories of S&P).



          “Moody’s” means Moody’s Investors Service Inc., a subsidiary of Moody’s Corporation, and its
successors.



          “S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc.,
and its successors.



          “Rating Agency” means each of Moody’s, S&P and Fitch; provided, that if any of Moody’s, S&P
and Fitch ceases to provide rating services to issuers or investors, the Company may appoint a
replacement for such Rating Agency that is reasonably acceptable to the Trustee.



-6-









 





          “Voting Stock” of any specified Person as of any date means the capital stock of such Person
that is at the time entitled to vote generally in the election of the board of directors of such
Person.



          SECTION 1.06 Denominations. The Notes shall be issued only in fully registered
book-entry form, without coupons, in denominations of $2,000 and integral multiples of $1,000 in
excess thereof.

          This Security is one of a duly authorized issue of 4.95% Senior Notes Due 2021 (the
“Securities”) of L-3 Communications Corporation, a Delaware corporation (the “Issuer”). The Issuer
issued the Securities under an Indenture dated as of May 21, 2010 (the “Original Indenture”) among
the Issuer, the guarantors listed on the signature pages thereto and The Bank of New York Mellon
Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the Second Supplemental
Indenture dated as of February 7, 2011 (the “Second Supplemental Indenture” and, together with the
Original Indenture, the “Indenture”). Capitalized terms used herein for which no definition is
provided herein shall have the meanings set forth in the Indenture.




     1. Interest. The Issuer promises to pay interest on the principal amount of this Security at
4.95% per annum from February 7, 2011 until maturity. The Issuer will pay interest semiannually on
February 15 and August 15 of each year, or if any such day is not a Business Day, on the next
succeeding Business Day. Interest on the Securities will accrue from the most recent interest
payment date on which interest has been paid or, if no interest has been paid, from February 7,
2011; provided that if there is no existing Default in the payment of interest, and if this
Security is authenticated between a record date referred to on the face hereof and the next
succeeding interest payment date, interest shall accrue from such next succeeding interest payment
date; provided, further, that the first interest payment date shall be August 15, 2011. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.



     2. Method of Payment. The Issuer will pay interest on the Securities (except defaulted
interest) to the Persons who are registered Holders of Securities at the close of business on the
record date next preceding the interest payment date, even if such Securities are canceled after
such record date and on or before such interest payment date. The Holder must surrender this
Security to a Paying Agent to collect principal payments. The Issuer will pay the principal of and
interest on the Securities in money of the United States of America that at the time of payment is
legal tender for payment of public and private debts. Such amounts shall be payable at the offices
of the Trustee or any Paying Agent, provided that at the option of the Issuer, the Issuer may pay
such amounts (1) by wire transfer with respect to Securities represented by a Global Note or (2) by
check payable in such money mailed to a Holder’s registered address with respect to any Security.



     3. Paying Agent and Registrar. Initially, the Trustee will act as Paying Agent and Registrar.
The Issuer may change any Paying Agent, Registrar, co-registrar or additional paying agent without
notice to any Holder. The Issuer or any of the Issuer’s subsidiaries may act in any such capacity.



     4. Indenture. The terms of the Securities include those stated in the Indenture and the
provisions made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended
(15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Second



A-5









 




Supplemental Indenture; provided, that if any provision of the Indenture limits, qualifies or
conflicts with the duties imposed by operation of TIA Section 318(c), the imposed duties shall
control. Holders are referred to the Indenture and the TIA for a statement of such terms and
provisions. The Securities are unsecured senior obligations of the Issuer and rank equally with
all of the Issuer’s existing and future unsecured indebtedness. The Indenture provides for the
issuance of other Series of debt securities thereunder.




     5. Optional Redemption.



          (a) The Issuer may, at its option, redeem the Securities in whole at any time or in part from
time to time, on at least 30 but not more than 60 days’ prior notice, at a redemption price equal
to the greater of:



     (i) 100% of the principal amount of the Securities being redeemed, and



     (ii) the present value of the Remaining Scheduled Payments on the Securities being
redeemed on the redemption date, discounted to the date of redemption, on a semiannual
basis, at the Treasury Rate plus 25 basis points.



          (b) If the Issuer elects to redeem the Securities, it will also pay accrued and unpaid
interest, if any, to the date of redemption, subject to the rights of Holders on the relevant
record date to receive interest due on the relevant interest payment date. In determining the
redemption price and accrued interest, interest will be calculated on the basis of a 360-day year
consisting of twelve 30-day months.



          (c) On or after November 15, 2020, the Securities will be redeemable, in whole or in part, at
a redemption price equal to 100% of the principal amount of the Securities to be redeemed, plus
accrued interest to the date of redemption.



     6. Mandatory Redemption.



          Except as set forth in paragraph 7 below, the Issuer shall not be required to make mandatory
redemption payments with respect to the Securities.




     7. Repurchase At Option Of Holder.



          Upon the occurrence of a Change of Control Triggering Event, unless the Issuer has exercised
its right to redeem the Securities as described above, each Holder will have the right to require
the Issuer to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in
excess thereof) of such Holder’s Securities pursuant to the offer described below (the “Change of
Control Offer ”) at an offer price in cash equal to 101% of the aggregate principal amount thereof
plus accrued and unpaid interest to the date of purchase (the “Change of Control Payment ”),
subject to the rights of Holders on the relevant record date to receive interest due on the
relevant interest payment date; provided, that the Issuer will not be required to make a Change of
Control Offer upon a Change of Control Triggering Event if a third party makes the Change of
Control Offer in the manner, at the times and otherwise in compliance with the requirements set
forth in the Indenture applicable to a Change of Control Offer made by the



A-6









 




Issuer and purchases all Securities validly tendered and not withdrawn under such Change of
Control Offer. Within 30 days following the date upon which any Change of Control Triggering Event
occurs, or at the Issuer’s option, prior to any Change of Control Triggering Event but subject to
the occurrence of a Change of Control Triggering Event, the Issuer will mail a notice to each
Holder describing the events constituting a Change of Control Triggering Event (including the
transaction or transactions that constitute the Change of Control) and offering to repurchase
Securities on the date specified in such notice, which date will be no earlier than 30 days and no
later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”),
pursuant to the procedures required by the Indenture and described in such notice. The notice, if
mailed prior to the occurrence of the Change of Control Triggering Event, will state that the
Change of Control Offer is conditioned on the occurrence of a Change of Control Triggering Event on
or prior to the Change of Control Payment Date. The Issuer shall comply with the requirements of
Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the repurchase of the Securities
as a result of a Change of Control Triggering Event.




     8. Notice of Redemption.



          Notice of redemption will be mailed at least 30 days but not more than 60 days before the
redemption date to each Holder whose Securities are to be redeemed at its registered address.
Securities in denominations larger than $2,000 may be redeemed in part but only in whole multiples
of $1,000, unless all of the Securities held by a Holder are to be redeemed. On and after the
redemption date interest ceases to accrue on Securities or portions thereof called for redemption.



     9. Denominations, Transfer, Exchange.



          The Securities are in registered form without coupons in denominations of $2,000 and integral
multiples of $1,000 in excess thereof. The transfer of Securities may be registered and Securities
may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents and the Issuer may
require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The
Issuer need not exchange or register the transfer of any Security or portion of a Security selected
for redemption, except for the unredeemed portion of any Security being redeemed in part. Also, it
need not exchange or register the transfer of any Securities for a period of 15 days before a
selection of Securities to be redeemed or during the period between a record date and the
corresponding interest payment date.



     10. Persons Deemed Owners.



          The registered Holder of a Security may be treated as its owner for all purposes.



     11. Amendment, Supplement and Waiver.



          Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented
with the consent of the Holders of at least a majority in principal amount of the then outstanding
Securities, and any existing default or compliance with any provision of the



A-7









 




Indenture or the Securities may be waived with the consent of the Holders of a majority in
principal amount of the then outstanding Securities (including consents obtained in connection with
a purchase of, or tender offer or exchange offer for, the Securities). Without the consent of any
Holder of a Security, the Indenture or the Securities may be amended or supplemented to cure any
ambiguity, defect or inconsistency, to provide for uncertificated Securities in addition to or in
place of certificated Securities, to provide for the assumption of the Issuer’s obligations to
Holders of the Securities in case of a merger or consolidation, to make any change that would
provide any additional rights or benefits to the Holders of the Securities or that does not
adversely affect the legal rights under the Indenture of any such Holder, to secure the Securities
or to add additional guarantors), to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act or to conform the text of
the Indenture or the Securities to any provision in the Prospectus, dated March 29, 2010, as
supplemented by the Prospectus Supplement, dated February 2, 2011, with respect to the Securities,
under the caption “Description of the Senior Notes,” to the extent that such provision was intended
to be a verbatim recitation of the Indenture, the Subsidiary Guarantees or the Securities.




     12. Defaults and Remedies.



          An “Event of Default” means any of the following: (i) default for 30 days in the payment when
due of interest with respect to, the Securities; (ii) default in payment when due of the principal

Indenture or the Securities for 90 days after written notice is received by the Issuer and the
Trustee from the Holders of at least 25% in aggregate principal amount of the Securities then
outstanding; (v) default under any mortgage, indenture or instrument under which there may be
issued or by which there may be secured or evidenced any Indebtedness of the Issuer or any of its
Subsidiaries (or the payment of which is guaranteed by the Issuer or any of its Subsidiaries)
whether such Indebtedness or guarantee now exists, or is created after the date hereof, which
default relates to a payment at final maturity or results in the acceleration of such Indebtedness
prior to its express maturity and, in each case, the principal amount of such Indebtedness,
together with the principal amount of all other Indebtedness that is not paid at final maturity or
results in the maturity of which has been so accelerated, aggregates $100.0 million or more; (vi)
failure by the Issuer or any of its Subsidiaries to pay final judgments aggregating in excess of
$100.0 million, which judgments are not paid, discharged or stayed for a period of 60 days; (vii)
certain events of bankruptcy or insolvency with respect to the Issuer or any of its Significant
Subsidiaries; and (viii) except as permitted by the Indenture, any Subsidiary Guarantee of a
Significant Subsidiary shall be held in any judicial proceeding to be unenforceable or invalid.



          If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25%
in principal amount of the then outstanding Securities by notice in writing, may declare the
principal amount of and accrued and unpaid interest on all the Securities to be due and payable
immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, with respect to the Issuer or any Significant
Subsidiary, the principal amount of and accrued and unpaid interest on all the Securities will
become due and payable without further action or notice. Holders of the



A-8









 




Securities may not enforce the Indenture or the Securities except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then
outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Securities notice of any continuing Default or Event of Default
(except a Default or Event of Default relating to the payment of principal, premium or interest) if
it determines that withholding notice is in their interest.




          The Holders of a majority in aggregate principal amount of the Securities then outstanding by
notice to the Trustee may on behalf of the Holders of all of the Securities waive any existing
Default or Event of Default and its consequences under the Indenture except a continuing Default or
Event of Default in the payment of interest on, or the principal of, the Securities.




     13. Trustee Dealings with Issuer.



          The Trustee, in its individual or any other capacity, may make loans to, accept deposits from,
and perform services for the Issuer or its Affiliates, and may otherwise deal with the Issuer or
its Affiliates, as if it were not the Trustee.



     14. No Recourse against Others.



          A director, officer, employee, incorporator or stockholder, of the Issuer or any Subsidiary of
the Issuer, as such, shall not have any liability for any obligations of the Issuer or any
Subsidiary of the Issuer under the Securities, the Indenture or the Subsidiary Guarantees or for
any claim based on, in respect of, or by reason of, such obligations or their creation. Each
Holder by accepting a Security waives and releases all such liability. The waiver and release are
part of the consideration for the issuance of the Securities.



     15. Authentication. The Securities shall not be valid until authenticated by the manual
signature of the Trustee or an authenticating agent.



     16. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the
Securities as a convenience to the Holders of the Securities. No representation is made as to the
accuracy of such numbers as printed on the Securities and reliance may be placed only on the other
identification numbers printed thereon.



     17. Indenture to Control; Governing Law. In the case of any conflict between the provisions
of this Security and the Indenture, the provisions of the Indenture shall control. The Indenture
and the Securities shall be governed by and construed under the laws of the State of New York.
