Dear Sirs and Mesdames:

     Harris Corporation, a Delaware corporation (the "COMPANY"), proposes to
issue and sell to the several Underwriters named in Schedule I hereto (the
"UNDERWRITERS") $300,000,000 principal amount of its 5% Notes due 2015 (the
"SECURITIES") to be issued pursuant to the provisions of an Indenture dated as
of September 3, 2003 (the "INDENTURE") between the Company and The Bank of New
York, as Trustee (the "TRUSTEE").

     The Company has filed with the Securities and Exchange Commission (the
"COMMISSION") a registration statement on Form S-3 (file number 333-108486),
including a related base prospectus, relating to the Securities. The
registration statement at the time it was last deemed amended, including the
information (if any) deemed to be part of the registration statement at the time
of effectiveness pursuant to Rule 430A under the Securities Act of 1933, as
amended (the "SECURITIES ACT"), is hereinafter referred to as the "REGISTRATION
STATEMENT".

     The "BASIC PROSPECTUS" shall mean the prospectus referred to above
contained in the Registration Statement at the Effective Date, including any
Preliminary Final Prospectus.

     The "FINAL PROSPECTUS" shall mean the prospectus supplement relating to the
Securities that was first filed pursuant to Rule 424(b) under the Securities Act
after the Effective Date, together with the Basic Prospectus.

     The "PRELIMINARY FINAL PROSPECTUS" shall mean any preliminary prospectus
supplement to the Basic Prospectus which describes the Securities and the
offering thereof and is used prior to filing of the Final Prospectus, together
with the Basic Prospectus.

     References to the Registration Statement, the Basic Prospectus, any
Preliminary Final Prospectus or the Final Prospectus shall include documents
incorporated therein by reference.

     The "EFFECTIVE DATE" shall mean the date and time that the Registration
Statement and any post-effective amendment or amendments thereto became or
become effective.

     The terms "SUPPLEMENT" and "AMENDMENT" or "AMEND" as used in this Agreement
with respect to the Registration Statement, the Basic Prospectus, any
Preliminary Final Prospectus or the Final Prospectus shall include all documents
subsequently filed by the Company with the Commission pursuant to the Securities
Exchange Act of 1934, as amended (the "EXCHANGE ACT"), that are deemed to be
incorporated by reference in the Basic Prospectus, any Preliminary Final
Prospectus or the Final Prospectus.

     1. Representations and Warranties. The Company represents and warrants to
and agrees with each of the Underwriters that:

     (a) The Company meets the requirements for use of Form S-3 under the
Securities Act, and the Registration Statement has become effective; no stop
order suspending the effectiveness of the Registration Statement is in effect,
and no proceedings for such purpose are pending before or threatened by the
Commission.

     (b) (i) Each document, if any, filed or to be filed pursuant to the
Exchange Act and incorporated by reference in the Final Prospectus complied or
will comply when so filed in all material respects with the Exchange Act and the
applicable rules and regulations of the Commission thereunder, (ii) the

amended or supplemented, if applicable, will not contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein

Registration Statement and the Final Prospectus comply and, as amended or
supplemented, if applicable, will comply in all material respects with the
Securities Act and the applicable rules and regulations of the Commission
thereunder and (iv) the Final Prospectus does not contain and, as amended or
supplemented, if applicable, will not contain any untrue statement of a material
fact or omit to state a material fact necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading,
except that the representations and warranties set forth in this paragraph do
not apply to (A) statements or omissions in the Registration Statement or the
Final Prospectus based upon information relating to any Underwriter furnished to
the Company in writing by such Underwriter through you expressly for use therein
or (B) that part of the Registration Statement that constitutes the Statement of
Eligibility (Form T-1)


                                       2

other instrument binding upon the Company or any of its subsidiaries that is
material to the Company and its subsidiaries, taken as a whole, or any judgment,
order or decree of any governmental body, agency or court having jurisdiction
over the Company or any subsidiary, and no consent, approval, authorization or
order of, or qualification with, any governmental body or agency is required for
the performance by the Company of its obligations under this Agreement, the
Indenture or the Securities, except such as may be required by the securities or
Blue Sky laws of the various states in connection with the offer and sale of the
Securities.

     (i) There has not occurred any material adverse change, or any development
involving a prospective material adverse change, in the condition, financial or

the properties of the Company or any of its subsidiaries is subject which the
Company has reason to believe would have a material adverse effect on the

the Company to perform its obligations under this Agreement, the Indenture or
the Securities or to consummate the transactions contemplated by the Final
Prospectus.

     (k) Any Preliminary Final Prospectus or Final Prospectus filed pursuant to
Rule 424 under the Securities Act, complied or will comply when so filed in all

regulations of the Commission thereunder.

     (l) The Company is not, and after giving effect to the offering and sale of
the Securities and the application of the proceeds thereof as described in the
Final Prospectus will not be, required to register as an "investment company" as

     (m) The Company and its subsidiaries (i) are in compliance with any and all
applicable foreign, federal, state and local laws and regulations relating to

have received all permits, licenses or other approvals required of them under
applicable Environmental Laws to conduct their respective businesses and (iii)
are in compliance with all terms and conditions of any such permit, license or

                                       4

receive required permits, licenses or other approvals or failure to comply with
the terms and conditions of such permits, licenses or approvals would not,
singly or in the aggregate, have a material adverse effect on the Company and
its subsidiaries, taken as a whole.

     (n) There are no costs or liabilities associated with Environmental Laws
(including, without limitation, any capital or operating expenditures required
for clean-up, closure of properties or compliance with Environmental Laws or any
permit, license or approval, any related constraints on operating activities and
any potential liabilities to third parties) which would, singly or in the
aggregate, have a material adverse effect on the Company and its subsidiaries,
taken as a whole.

     (o) None of the Company and its subsidiaries or, to the best knowledge of

foreign or domestic government official or employee from corporate funds or
(iii) made any bribe, rebate, payoff, influence payment, kickback or other
unlawful payment, except in the case of clauses (B)(i), (B)(ii) and (B)(iii),
which would not, singly or in the aggregate, have a material adverse effect on
the Company and its subsidiaries, taken as a whole.

     2. Agreements to Sell and Purchase. The Company hereby agrees to sell to
the several Underwriters, and each Underwriter, upon the basis of the
representations and warranties herein contained, but subject to the conditions
hereinafter stated, agrees, severally and not jointly, to purchase from the
Company the respective principal amounts of Securities set forth in Schedule I
hereto opposite its name at 98.725% of their principal amount plus accrued
interest, if any, from September 20, 2005 to the date of payment and delivery.

     The Company hereby agrees that, without the prior written consent of Morgan
Stanley & Co. Incorporated and Banc of America Securities LLC, on behalf of the
Underwriters, it will not during the period beginning on the date hereof and
continuing to and including the Closing Date (as defined in Section 4), offer,
sell, contract to sell or otherwise dispose of any debt securities of the
Company or warrants to purchase or otherwise acquire debt securities of the
Company substantially similar to the Securities (other than (i) the Securities
and (ii) commercial paper issued in the ordinary course of business).

     3. Terms of Public Offering. The Company is advised by you that the
Underwriters propose to make a public offering of their respective portions of
the


                                       5

Securities as soon after this Agreement has been entered into as in your
judgment is advisable. The Company is further advised by you that the Securities
are to be offered to the public initially at 99.375% of their principal amount
(the "PUBLIC OFFERING PRICE") plus accrued interest, if any, from September 20,
2005 to the date of payment and delivery and to certain dealers selected by you
at a price that represents a concession not in excess of 0.40% of their
principal amount.

     4. Payment and Delivery. Payment for the Securities shall be made to the
Company in Federal or other funds immediately available in New York City at
10:00 a.m., New York City time, on September 20, 2005, or at such other time on
the same or such other date, not later than September 23, 2005, as shall be
designated in writing by you. The time and date of such payment are hereinafter
referred to as the "CLOSING DATE."

     Payment for the Securities shall be made against delivery to you on the
Closing Date for the respective accounts of the several Underwriters of the
Securities registered in such names and in such denominations as you shall
request in writing not less than one full business day prior to the Closing
Date, with any transfer taxes payable in connection with the transfer of the
Securities to the Underwriters duly paid.

     5. Conditions to the Underwriters' Obligations. The obligations of the
Company to sell the Securities to the Underwriters and the several obligations
of the Underwriters to purchase and pay for the Securities are subject to the
following conditions:

     (a) Subsequent to the execution and delivery of this Agreement and prior to
the Closing Date:

          (i) there shall not have occurred any downgrading, nor shall any
     notice have been given of any intended or potential downgrading or of any
     review for a possible change that does not indicate the direction of the
     possible change, in the rating accorded the Company or any of the Company's
     securities, or in the rating outlook for the Company, by any "nationally
     recognized statistical rating organization," as such term is defined for
     purposes of Rule 436(g)(2) under the Securities Act; and

          (ii) there shall not have occurred any change, or any development
     involving a prospective change, in the condition, financial or otherwise,
     or in the earnings, business or operations of the Company and its
     subsidiaries, taken as a whole, from that set forth in the Final
     Prospectus, exclusive of any amendments or supplements thereto subsequent
     to the date of this Agreement that, in your judgment, is material and
     adverse and that makes it, in your judgment, impracticable


                                       6

     or inadvisable to market, sell or deliver the Securities on the terms and
     in the manner contemplated in the Final Prospectus.

     (b) The Underwriters shall have received on the Closing Date a certificate,
dated the Closing Date and signed by an executive officer of the Company, to the
effect set forth in Section 5(a)(i) above and to the effect that the
representations and warranties of the Company contained in this Agreement are
true and correct as of the Closing Date and that the Company has complied with
all of the agreements and satisfied all of the conditions on its part to be
performed or satisfied hereunder on or before the Closing Date.

     The officer signing and delivering such certificate may rely upon the best
of his or her knowledge as to proceedings threatened.

     (c) The Underwriters shall have received on the Closing Date an opinion of
Holland & Knight, outside counsel for the Company, dated the Closing Date, to
the effect set forth in Exhibit A-1 and an opinion of Scott T. Mikuen, Vice
President-Associate General Counsel, of the Company, to the effect set forth in
Exhibit A-2. Such opinions shall be rendered to the Underwriters at the request
of the Company and shall so state therein.

     (d) The Underwriters shall have received on the Closing Date such opinion
or opinions of Cravath, Swaine & Moore LLP, counsel for the Underwriters, dated
the Closing Date with respect to the issuance and sale of the Securities, the
Registration Statement, the Final Prospectus and other related matters as the
Underwriters may reasonably require.

     (e) The Underwriters shall have received, on each of the date hereof and
the Closing Date, a letter dated the date hereof or the Closing Date, as the
case may be, in form and substance reasonably satisfactory to the Underwriters,
from Ernst & Young, independent public accountants, containing statements and
information of the type ordinarily included in accountants' "comfort letters" to
underwriters with respect to the financial statements and certain financial
information contained in or incorporated by reference into the Registration
Statement and the Final Prospectus; provided that the letter delivered on the
Closing Date shall use a "cut-off date" not earlier than the date hereof.

     6. Covenants of the Company. In further consideration of the agreements of
the Underwriters herein contained, the Company covenants with each Underwriter
as follows:

     (a) To furnish to you in New York City, without charge, prior to 10:00 a.m.
New York City time on the business day next succeeding the date of this
Agreement and during the period mentioned in Section 6(c) below, as many copies
of the Final Prospectus, any documents incorporated therein by reference and any
supplements and amendments thereto as you may reasonably request.


                                       7

     (b) Prior to completion of the distribution of the Securities (as
determined by the Underwriters), before amending or supplementing the
Registration Statement or the Final Prospectus, to furnish to you a copy of each
such proposed amendment or supplement and not to file any such proposed
amendment or supplement to which you reasonably object, and to file with the
Commission within the applicable period specified in Rule 424(b) under the
Securities Act any prospectus required to be filed pursuant to such Rule.

     (c) If, during such period after the first date of the public offering of
the Securities as in the opinion of counsel for the Underwriters the Final
Prospectus is required by law to be delivered in connection with sales by an
Underwriter or dealer, any event shall occur or condition exist as a result of
which it is necessary to amend or supplement the Final Prospectus in order to
make the statements therein, in the light of the circumstances when the Final
Prospectus is delivered to a purchaser, not misleading, or if, in the opinion of
counsel for the Underwriters, it is necessary to amend or supplement the Final
Prospectus to comply with applicable law, forthwith to prepare, file with the
Commission and furnish, at its own expense, to the Underwriters and to the
dealers (whose names and addresses you will furnish to the Company) to which
Securities may have been sold by you on behalf of the Underwriters and to any
other dealers upon request, either amendments or supplements to the Final
Prospectus so that the statements in the Final Prospectus as so amended or
supplemented will not, in the light of the circumstances when the Final
Prospectus is delivered to a purchaser, be misleading or so that the Final
Prospectus, as amended or supplemented, will comply with law.

     (d) To endeavor to qualify the Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions as you shall reasonably
request; provided that the Company will not be required to (i) qualify as a
foreign corporation or as a dealer in securities in any jurisdiction where it
would not otherwise be required to qualify but for this Agreement or (ii) take
any action that would subject it to general service of process in suits or to
taxation in any such jurisdiction where it is not then so subject.

     (e) To make generally available to the Company's security holders and to
you as soon as practicable an earning statement covering the twelve-month period
ending September 30, 2006 that satisfies the provisions of Section 11(a) of the
Securities Act and the rules and regulations of the Commission thereunder.

     (f) Whether or not the transactions contemplated in this Agreement are
consummated or this Agreement is terminated, to pay or cause to be paid all
expenses incident to the performance of its obligations under this Agreement,
including: (i) the fees, disbursements and expenses of the Company's counsel and
the Company's accountants in connection with the registration and delivery of
the Securities under the Securities Act and all other fees or expenses in
connection


                                       8

with the preparation and filing of the Registration Statement, any Preliminary
Final Prospectus, the Final Prospectus and amendments and supplements to any of
the foregoing, including all printing costs associated therewith, and the
mailing and delivering of copies thereof to the Underwriters and dealers, in the
quantities hereinabove specified, (ii) all costs and expenses related to the
transfer and delivery of the Securities to the Underwriters, including any
transfer or other taxes payable thereon, (iii) the cost of printing or producing
any Blue Sky or legal investment memorandum in connection with the offer and
sale of the Securities under state securities laws and all expenses in
connection with the qualification of the Securities for offer and sale under
state securities laws as provided in Section 6(d) hereof, including filing fees
and the reasonable fees and disbursements of counsel for the Underwriters in
connection with such qualification and in connection with the Blue Sky or legal
investment memorandum, (iv) any fees charged by the rating agencies for the
rating of the Securities, (v) the cost of the preparation, issuance and delivery
of the Securities, (vi) the costs and charges of any trustee, transfer agent,
registrar or depositary, (vii) all other costs and expenses incident to the
performance of the obligations of the Company hereunder for which provision is
not otherwise made in this Section. It is understood, however, that except as
provided in this Section, Section 7 entitled "Indemnity and Contribution," and
the last paragraph of Section 9 below, the Underwriters will pay all of their
costs and expenses, including fees and disbursements of their counsel, transfer
taxes payable on resale of any of the Securities by them and any advertising
expenses connected with any offers they may make.

     (g) The Company will cooperate with the Underwriters and use commercially
reasonable efforts to permit the Securities to be eligible for clearance and
settlement through The Depository Trust Company.

     7. Indemnity and Contribution. (a) The Company agrees to indemnify and hold
harmless each Underwriter, each person, if any, who controls any Underwriter
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act, and each affiliate of any Underwriter within the meaning of
Rule 405 under the Securities Act from and against any and all losses, claims,
damages and liabilities (including, without limitation, any legal or other
expenses reasonably incurred in connection with defending or investigating any
such action or claim) caused by any untrue statement or alleged untrue statement
of a material fact contained in the Registration Statement or any amendment
thereof, any Preliminary Final Prospectus or the Final Prospectus or any
amendment or supplement thereto, or caused by any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, except insofar as such losses,
claims, damages or liabilities are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to any


                                       9

Underwriter furnished to the Company in writing by such Underwriter through you
expressly for use therein.

     (b) Each Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors, its officers and each person, if any,
who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to such Underwriter, but only with
reference to information relating to such Underwriter furnished to the Company
in writing by such Underwriter through you expressly for use in the Registration
Statement, any Preliminary Final Prospectus, the Final Prospectus or any
amendments or supplements thereto.

     (c) In case any proceeding (including any governmental investigation) shall
be instituted involving any person in respect of which indemnity may be sought
pursuant to Section 7(a) or 7(b), such person (the "INDEMNIFIED PARTY") shall
promptly notify the person against whom such indemnity may be sought (the
"INDEMNIFYING PARTY") in writing and the indemnifying party, upon request of the
indemnified party, shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred. Such firm shall be
designated in writing by Morgan Stanley & Co. Incorporated and Banc of America
Securities LLC, in the case of parties indemnified pursuant to Section 7(a), and
by the Company, in the case of parties indemnified pursuant to Section 7(b). The
indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment. Notwithstanding the foregoing sentence, if at
any time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as contemplated
by the second and third sentences of this paragraph, the


                                       10

indemnifying party agrees that it shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 30 days after receipt by such indemnifying party of the
aforesaid request and (ii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or could have been a
party and indemnity could have been sought hereunder by such indemnified party,
unless such settlement includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding.

     (d) To the extent the indemnification provided for in Section 7(a) or 7(b)
is unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages or liabilities referred to therein, then each indemnifying party
under such paragraph, in lieu of indemnifying such indemnified party thereunder,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and the Underwriters on the other hand from the offering of the
Securities or (ii) if the allocation provided by clause 7(d)(i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause 7(d)(i) above but also the
relative fault of the Company on the one hand and of the Underwriters on the
other hand in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Underwriters on the other hand in connection with the offering of the
Securities shall be deemed to be in the same respective proportions as the net
proceeds from the offering of the Securities (before deducting expenses)
received by the Company and the total underwriting discounts and commissions
received by the Underwriters, in each case as set forth in the table on the
cover of the Final Prospectus, bear to the aggregate Public Offering Price of
the Securities. The relative fault of the Company on the one hand and the
Underwriters on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Underwriters' respective obligations to contribute
pursuant to this Section 7 are several in proportion to the respective principal
amounts of Securities they have purchased hereunder, and not joint.

     (e) The Company and the Underwriters agree that it would not be just or
equitable if contribution pursuant to this Section 7 were determined by pro rata


                                       11

allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in Section 7(d). The amount paid or payable
by an indemnified party as a result of the losses, claims, damages and
liabilities referred to in the immediately preceding paragraph shall be deemed
to include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 7, no Underwriter shall be required to contribute any
amount in excess of the amount by which the total price at which the Securities
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages that such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 7 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.

     (f) The indemnity and contribution provisions contained in this Section 7
and the representations, warranties and other statements of the Company
contained in this Agreement shall remain operative and in full force and effect
regardless of (i) any termination of this Agreement, (ii) any investigation made
by or on behalf of any Underwriter, any person controlling any Underwriter or
any affiliate of any Underwriter or by or on behalf of the Company, its officers
or directors or any person controlling the Company and (iii) acceptance of and
payment for any of the Securities.

     8. Termination. This Agreement shall be subject to termination by notice
given by you to the Company, if (a) after the execution and delivery of this
Agreement and prior to the Closing Date (i) trading generally shall have been
suspended or materially limited, or minimum or maximum prices for trading shall
have been fixed or maximum ranges for prices shall have been required, on or by,
as the case may be, any of the New York Stock Exchange, the American Stock
Exchange, the Nasdaq National Market, the Chicago Board of Options Exchange, the
Chicago Mercantile Exchange or the Chicago Board of Trade or the clearance or
settlement of such trading generally shall been materially disrupted, (ii)
trading of any securities of the Company shall have been suspended on any
exchange or in any over-the-counter market, (iii) a general moratorium on
commercial banking activities in New York shall have been declared by either
Federal or New York State authorities or a material disruption in commercial
banking in the United States shall have occurred or (iv) there shall have
occurred any outbreak or escalation of hostilities, including any act or acts of
terrorism, or any change in financial markets or any calamity or crisis that, in
your judgment, is material and adverse and (b) in the case of any of the events
specified in clauses 8(a)(i) through


                                       12

8(a)(iv), such event, singly or together with any other such event, makes it, in
your judgment, impracticable or inadvisable to market, sell or deliver the
Securities on the terms and in the manner contemplated in the Final Prospectus.

     9. Effectiveness; Defaulting Underwriters. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.

     If, on the Closing Date, any one or more of the Underwriters shall fail or
refuse to purchase Securities that it has or they have agreed to purchase
hereunder on such date, and the aggregate principal amount of Securities which
such defaulting Underwriter or Underwriters agreed but failed or refused to
purchase is not more than one-tenth of the aggregate principal amount of the
Securities to be purchased on such date, the other Underwriters shall be
obligated severally in the proportions that the principal amount of Securities
set forth opposite their respective names in Schedule I bears to the aggregate
principal amount of Securities set forth opposite the names of all such
non-defaulting Underwriters, or in such other proportions as you may specify, to
purchase the Securities which such defaulting Underwriter or Underwriters agreed
but failed or refused to purchase on such date; provided that in no event shall
the principal amount of Securities that any Underwriter has agreed to purchase
pursuant to this Agreement be increased pursuant to this Section 9 by an amount
in excess of one-ninth of such principal amount of Securities without the
written consent of such Underwriter. If, on the Closing Date, any Underwriter or
Underwriters shall fail or refuse to purchase Securities and the aggregate
principal amount of Securities with respect to which such default occurs is more
than one-tenth of the aggregate principal amount of Securities to be purchased
on such date, and arrangements satisfactory to you and the Company for the
purchase of such Securities are not made within 36 hours after such default,
this Agreement shall terminate without liability on the part of any
non-defaulting Underwriter or the Company. In any such case either you or the
Company shall have the right to postpone the Closing Date, but in no event for
longer than seven days, in order that the required changes, if any, in the
Registration Statement and in the Final Prospectus or in any other documents or
arrangements may be affected. Any action taken under this paragraph shall not
relieve any defaulting Underwriter from liability in respect of any default of
such Underwriter under this Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of them,
because of any failure or refusal on the part of the Company to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

                         OPINION OF HOLLAND & KNIGHT LLP

The opinion of the counsel for the Company, to be delivered pursuant to Section
5(c) of the Underwriting Agreement shall be to the effect that:

A. The Company has been duly incorporated, is validly existing as a corporation
in good standing under the laws of the State of Delaware, has the corporate
power and authority to own its property and to conduct its business as described
in the Final Prospectus. The Company is duly qualified to transact business in
California, Florida, Illinois, New York, Ohio and Texas, the Company's status is
active in the State of Florida, and the Company is in good standing in each
other jurisdiction listed in this paragraph.

B. The Underwriting Agreement has been duly authorized, executed and delivered
by the Company.

C. The Securities have been duly authorized by the Company and, when executed
and authenticated in accordance with the provisions of the Indenture and
delivered to and paid for by the Underwriters in accordance with the terms of
the Underwriting Agreement, will be valid and binding obligations of the
Company, enforceable in accordance with their terms, subject to applicable
bankruptcy, insolvency or similar laws affecting creditors' rights generally and
general principles of equity, and will be entitled to the benefits of the
Indenture pursuant to which such Securities are to be issued.

D. The Indenture has been duly authorized, executed and delivered by, and is a
valid and binding agreement of, the Company, enforceable in accordance with its
terms, subject to applicable bankruptcy, insolvency or similar laws affecting
creditors' rights generally and general principles of equity.

E. The Indenture has been duly qualified under the Trust Indenture Act.

F. The execution and delivery by the Company of, and the performance by the
Company of its obligations under, the Underwriting Agreement, the Indenture and
the Securities will not contravene (i) any provision of applicable laws for the
states of New York, Florida and Delaware and federal law ("Applicable Law") or
the certificate of incorporation or by-laws of the Company, (ii) any agreement
or other instrument listed as an exhibit to the Company's Annual Report on Form
10-K for the year ended July 1, 2005 (the "2005 Form 10-K") or Current Report on
Form 8-K dated September 2, 2005, or that would be required to be filed as a
material agreement exhibit to a quarterly report by the Company on Form 10-Q or
a Report on Form 8-K (provided, that in determining which documents would be

required to be so filed, such counsel may rely on an officer's certificate that
specifies the agreements that the Company would be required to be so filed), or
(iii) to the best of such counsel's knowledge, any judgment, order or decree of
any governmental body, agency or court having jurisdiction over the Company or
any subsidiary.

G. No consent, approval, authorization or order of, or qualification with, any
governmental body or agency is required under Applicable Law for the performance
by the Company of its obligations under the Underwriting Agreement, the
Indenture or the Securities, except such as may be required by the securities or
blue sky laws of the various states in connection with the offer and sale of the
Securities.

H. After due inquiry, such counsel does not know of any legal or governmental
proceedings pending or threatened to which the Company or any of its
subsidiaries is a party or to which any of the properties of the Company or any
of its subsidiaries is subject and that would be required to be described by the
Company in Item 3 of an annual report on Form 10-K, other than proceedings
fairly summarized in all material respects in the Final Prospectus; or (ii) any
statutes, regulations, contracts or other documents that are required to be
described in the Registration Statement or the Final Prospectus or to be filed
as exhibits to the Registration Statement that are not described or filed as
required.

I. The Company is not, and after giving effect to the offering and sale of the
Securities and the application of the proceeds thereof as described in the Final
Prospectus will not be, required to register as an "investment company" as such
term is defined in the Investment Company Act of 1940, as amended.

J. The statements in the Final Prospectus under the captions "Description of
Notes," and "Underwriters," "under the caption "Description of Debt Securities"
in the Basic Prospectus and in "Item 3-Legal Proceedings" of the 2005 Form 10-K,
insofar as such statements constitute summaries of the legal matters, documents
or proceedings referred to therein, fairly summarize the matters referred to
therein.

K. Such counsel (i) is of the opinion that each document filed pursuant to the
Exchange Act and incorporated by reference in the Registration Statement and the
Final Prospectus (except for the financial statements and financial schedules
and other financial and statistical data included therein, as to which such
counsel need not express any opinion) appeared on its face to be appropriately
responsive as of its filing date in all material respects to the requirements of
the Exchange Act and the applicable rules and regulations of the Commission
thereunder, (ii) in the opinion of such counsel, the Registration Statement and
the Final Prospectus (except for the financial statements and financial
schedules and other financial and statistical data included therein, as to which
such counsel need not express


                                        2

any opinion) appear on their face to be appropriately responsive in all material
respects to the requirements of the Securities Act and the applicable rules and
regulations of the Commission thereunder, and (A) nothing has come to the
attention of such counsel that causes such counsel to believe that (i) the
Registration Statement or the prospectus included therein (except for the
financial statements and financial schedules and other financial and statistical
data included therein and except for that part of the Registration Statement
that constitutes the Form T-1, as to which such counsel need not express any
belief) at the time the Registration Statement was last deemed amended contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading or (ii) the Final Prospectus (except for the financial statements and
financial schedules and other financial and statistical data included therein,
as to which such counsel need not express any belief) as of its date or as of
the Closing Date contained or contains any untrue statement of a material fact
or omitted or omits to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

With respect to the matters referred to in the paragraph above, counsel may
state that his or her opinions or beliefs are based upon his or her
participation in the preparation of the Final Prospectus (and any amendments or
supplements thereto) and in conferences with representatives of the Company and
the independent accountants of the Company, at which the contents of the Final
Prospectus were discussed and review of the documents incorporated by reference
therein but, except as set forth in paragraph J are without independent check or
verification.

contribution under the Underwriting Agreement, (ii) to the best of such
counsel's knowledge any agreement or other instrument binding upon the Company

Securities or to consummate the transactions contemplated by the Final
