Capitalized terms used but not defined herein shall have the meanings given to

          The Series A Notes will be offered and sold to you pursuant to an

as amended (the "Act"). The Company will prepare a preliminary offering
memorandum, dated July 25, 2005 (the "Preliminary Offering Memorandum") and a
final offering memorandum, dated July 27, 2005 (the "Offering Memorandum"),
relating to the Company, the Series A Notes and the Series A Guarantees, which
will incorporate by reference the Annual Report on Form 10-K of L-3

EVIDENCED HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE


                                        2



TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION
THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED
THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5
OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THE

CORPORATION THAT (A) SUCH SECURITY MAY BE RESOLD, PLEDGED OR OTHERWISE
TRANSFERRED, ONLY (1) (a) TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A
QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT)
IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (b) IN A TRANSACTION
MEETING THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT, (c) OUTSIDE THE
UNITED STATES TO A FOREIGN PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF
RULE 904 UNDER THE SECURITIES ACT OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN

THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER
FROM IT OF THE SECURITY EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN
(A) ABOVE."

          You have advised the Company that you will make offers (the "Exempt
Resales") of the Series A Notes purchased by you hereunder on the terms set
forth in the Offering Memorandum, as amended or supplemented, solely to (i)
persons whom you reasonably believe to be "qualified institutional buyers" as
defined in Rule 144A under the Securities Act ("QIBs"), and (ii) outside the
United States to persons other than U.S. Persons in offshore transactions
meeting the requirements of Rule 904 of Regulation S ("Regulations S") under the
Securities Act (such persons specified in clauses (i) and (ii) being referred to
herein as the "Eligible Purchasers"). As used herein, the terms "offshore
transaction," "United States" and "U.S. person" have the respective meanings
given to them in Regulation S. You will offer the Series A Notes to Eligible
Purchasers initially at a price equal to 100% of the principal amount thereof.
Such price may be changed at any time without notice.

          Holders (including subsequent transferees) of the Series A Notes will
have the registration rights set forth in the registration rights agreement (the
"Registration Rights Agreement"), to be dated July 29, 2005 (the "Closing
Date"), in the form of Exhibit C hereto, for so long as such Series A Notes
constitute "Transfer Restricted Securities" (as defined in the Registration
Rights Agreement). Pursuant to the Registration Rights Agreement, the Company
and the Guarantors will agree to file with the Securities and Exchange
Commission (the "Commission") under the circumstances set forth therein, (i) a
registration statement under the Securities Act (the "Exchange Offer
Registration Statement") relating to the Company's 6 3/8% Senior Subordinated
Notes due 2015 (the "Series B Notes" and, together with the Series A Notes, the
"Notes") and the guarantees thereof (the "Series B Guarantees" and, together
with the Series A Guarantees, the "Guarantees") to be offered in exchange for
the Series A Notes and Guarantees, (such offer to exchange being referred to
collectively as the "Registered Exchange Offer") and (ii) a shelf registration
statement pursuant to Rule 415 under the Securities Act (the "Shelf Registration
Statement") relating to the resale by certain holders of the Series A Notes, and
to use all commercially reasonable efforts to cause such Registration Statements
to be declared effective. This Agreement, the Notes, the Guarantees (as defined
herein), the Indenture and the Registration Rights Agreement are hereinafter
referred to collectively as the "Operative Documents." This is to confirm the
agreements concerning the purchase of the Series A Notes from the Company by
you.

title to all property (real and personal) described in the Offering Memorandum

or other encumbrances except such as are described in the Offering Memorandum or

property described in the Offering Memorandum as being held under lease by the
Company and its subsidiaries is held by them under valid, subsisting and
enforceable leases, with only such exceptions as would not have a Material
Adverse Effect (individually or in the aggregate).

          (v) The Company and each of its subsidiaries own or possess adequate
rights to use all material patents, trademarks, service marks, trade names,
copyrights, licenses, inventions, trade secrets and other rights, and all

aggregate), and the Company is not aware of any pending or threatened claim to
the contrary or any pending or threatened challenge by any other person to the
rights of the Company and its subsidiaries with respect to the foregoing which,
if determined adversely to the Company and its subsidiaries, would have a
Material Adverse Effect (individually or in the aggregate).

          (w) Except as described in the Offering Memorandum or in the documents
incorporated therein by reference, there are no legal or governmental
proceedings pending or, to the knowledge of the Company, threatened, against the
Company or any of its subsidiaries or to which the Company or any of its
subsidiaries is a party or of which any property or assets of the Company or any
of its subsidiaries is the subject which, if determined adversely to the Company
or any of its subsidiaries, are reasonably likely to cause a Material Adverse
Effect.

          (x) There are no contracts or other documents which would be required
to be described in a prospectus contained in a registration statement on Form
S-3 by the Securities Act or by the rules and regulations thereunder which have

therein by reference.

          (y) No material relationship, direct or indirect, exists between or

published interpretations thereunder (the "Code") (other than contributions in
the normal course which are not in default); and each "pension plan" for which
the Company would have any liability that is intended to be qualified under
Section 401(a) of the Code is so qualified in all material respects and nothing
has occurred, whether by action or by failure to act, which would reasonably be
expected to cause the loss of such qualification.

          (bb) The Company and its subsidiaries have filed all federal, state
and local income and franchise tax returns required to be filed through the date
hereof and have paid all taxes due thereon, and no tax deficiency has been

Investment Company Act of 1940 and the rules and regulations of the Commission
thereunder.

          (gg) Neither the Company nor any affiliate (as defined in Rule 501(b)
of Regulation D ("Regulation D") under the Securities Act) of the Company has

quoted in a U.S. automated inter-dealer quotation system.

          (jj) Assuming (i) that your representations and warranties in Section
2 are true, (ii) compliance by you with your covenants set forth in Section 2
and (iii) that each of the Eligible Purchasers is a QIB or a person who is not a
"U.S. person" who acquires the Series A Notes outside the United States in an
"offshore transaction" (within the meaning of Rule 904 of Regulation S), the

provision of the Securities Act. The Company makes no representation in this
paragraph (jj) with respect to the Initial Purchasers.

          (ll) The Company is a "reporting issuer" as defined in Rule 902 under

required under the Exchange Act are being prepared; (ii) have been evaluated for
effectiveness as of the end of the period covered by the Company's most recent
annual or quarterly report filed with the Commission; and (iii) are effective in
all material respects to perform the functions for which they were established.

          (nn) Based on the evaluation of its disclosure controls and
procedures, the Company is not aware of (i) any significant deficiency in the
design or operation of internal controls over financial reporting which could
adversely affect the Company's ability to record, process, summarize and report
financial data or any material weaknesses in internal controls or (ii) any
fraud, whether or not material, that involves management or other employees who
have a significant role in the Company's internal controls over financial
reporting.

          (oo) Since the date of the most recent evaluation of such disclosure
controls and procedures, there have been no significant changes in internal
controls or in other factors that could


                                       10

regard to significant deficiencies and material weaknesses.

Securities Act), it will have sent to each distributor, dealer or person
receiving a selling concession, fee or other remuneration that purchases Series
A Notes from it during the Restricted Period a confirmation or notice
substantially to the following effect:

          (a) To advise you promptly and, if requested by you, to confirm such
advice in writing, of (i) the issuance by any state securities commission of any
stop order suspending the qualification or exemption from qualification of any
Series A Notes or Series A Guarantees for offering or sale in any jurisdiction,
or the initiation or threatening of any proceeding for such purpose by the
Commission or any state securities commission or other regulatory authority, and
(ii) the happening of any event that makes any statement of a material fact made
in the Offering Memorandum untrue or which requires the making of any additions
to or changes in the Offering Memorandum in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The Company shall use all commercially reasonable efforts to prevent
the issuance of any stop order or order suspending the qualification or
exemption of the Series A Notes or Series A Guarantees under any state
securities or Blue Sky laws and, if at any time any state securities commission
shall issue any stop order suspending the qualification or exemption of the
Series A Notes or Series A Guarantees under any state securities or Blue Sky
laws, the Company shall use every reasonable effort to obtain the withdrawal or
lifting of such order at the earliest possible time.

          (b) To furnish to you, as many copies of the Offering Memorandum, and
any amendments or supplements thereto, as you may reasonably request. Such
copies shall be furnished without charge for use in connection with the Exempt
Resales for the nine-month period immediately following the Closing Date. The

amendment or supplement within a reasonable time, but in any event not longer
than five days after being furnished a copy of such amendment or supplement. The
Company shall promptly prepare, upon any reasonable request by you, any
amendment or supplement to the Offering Memorandum that may be necessary or
advisable in connection with Exempt Resales.

          (d) If, in connection with any Exempt Resales or market making
transactions after the date of this Agreement and prior to the consummation of
the Registered Exchange Offer, any event shall occur that, in the judgment of
the Company or in the reasonable judgment of counsel to you, makes any statement
of a material fact in the Offering Memorandum untrue or that requires the making
of any additions to or changes in the Offering Memorandum in order to make the
statements in the Offering Memorandum, in light of the circumstances under which
they were made at the time that the Offering Memorandum is delivered to
prospective Eligible Purchasers, not misleading, or if it is necessary to amend
or supplement the Offering Memorandum to comply with applicable law, the Company
shall promptly notify you of such event and prepare an appropriate amendment or
supplement to the Offering Memorandum so that (i) the statements in the Offering
Memorandum as amended or supplemented will, in light of the circumstances under
which they were made at the time that the Offering Memorandum is delivered to

Purchasers may reasonably request to qualify the Series A Notes and the Series A
Guarantees for offering and sale under the securities laws of such jurisdictions
as the Initial Purchasers may request (provided, however, that the Company shall
not be obligated to qualify as a foreign corporation in any jurisdiction in
which it is not now so qualified or to take any action that would subject it to
taxation or to general consent to service of process in any jurisdiction in
which it is not now so subject) and to comply with such laws so as to permit the
continuance of sales and dealings therein in such jurisdictions for as long as
may be necessary to complete the distribution of the Series A Notes and the
Series A Guarantees.

          (f) Prior to the Closing Date, to furnish to you, as soon as they have
been prepared, a copy of any internal consolidated financial statements of the
Company for any period subsequent to the period covered by the financial
statements appearing in the Offering Memorandum.

          (g) To use all commercially reasonable efforts to do and perform all
things required to be done and performed under this Agreement by it prior to or
after the Closing Date and to satisfy all conditions precedent on its part to
the delivery of the Series A Notes and the Series A Guarantees.

          (h) Not to sell, offer for sale or solicit offers to buy or otherwise
negotiate in respect of any security (as defined in the Securities Act) that

require the registration under the Securities Act of the sale to you or the
Eligible Purchasers of Series A Notes.

          (i) During any period in which the Company is not subject to Section
13 or 15(d) of the Exchange Act within the two-year period following the Closing
Date, to make available to any registered holder or beneficial owner of Series A

meaning of such term under the United States Investment Company Act of 1940 and
the rules and regulations of the Commission thereunder.

          (m) To take such steps as shall be necessary to ensure that all the

become guarantors of the Notes to the extent required by the terms of the
Indenture.

          (n) For a period of 90 days from the date of the issuance of the

guaranteed by the Company, except (i) for the Series B Notes in connection with
the Registered Exchange Offer or (ii) with the prior consent of Lehman Brothers
Inc.

          6. No fiduciary duty. The Company acknowledges and agrees that in
connection with this offering and sale of the Series A Notes or any other
services the Initial Purchasers may be deemed to be providing hereunder,
notwithstanding any preexisting relationship, advisory or otherwise, between the

supplements thereto, which shall be reasonably satisfactory in all material
respects to counsel for the Initial Purchasers, to the Initial Purchasers.

          (h) The Company and the Guarantors shall have furnished to the Initial
Purchasers a certificate, dated the Closing Date and delivered on behalf of the
Company or the Guarantors, as the case may be, of their respective Chairman of
the Board, their respective President or a Vice President and their respective
Chief Financial Officer stating that:


                                       16



               (i) The representations and warranties of the Company and the
Guarantors in Section 1 are true and correct as of the Closing Date; the Company
and the Guarantors have complied with all their agreements contained herein; and
the conditions set forth in Sections 8(i) and 8(j) have been fulfilled; and

               (ii) They have carefully examined the Offering Memorandum and, in
their opinion (A) the Offering Memorandum as of its date and as of the Closing
Date, did not include any untrue statement of a material fact and did not omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading, and (B) since the date of the Offering
Memorandum, no event has occurred which should have been set forth in a
supplement or amendment to the Offering Memorandum.

          (i) (i) Neither the Company nor any of its subsidiaries shall have
sustained since the date of the latest audited financial statements incorporated
by reference in the Offering Memorandum any material loss or interference with
its business from fire, explosion, flood or other calamity, whether or not
covered by insurance, or from any labor dispute or court or governmental action,
order or decree, otherwise than as set forth or contemplated in the Offering
Memorandum (or in the documents incorporated therein by reference) or (ii) since
such date there shall not have been any change in the capital stock or long-term
debt of the Company or any of its subsidiaries or any change, or any development
involving a prospective change, in or affecting the business, management,
financial position, stockholders' equity or results of operations of the Company
and its subsidiaries taken as a whole, otherwise than as set forth or
contemplated in the Offering Memorandum (or in the documents incorporated
therein by reference), the effect of which, in any such case described in clause
(i) or (ii), is, in the judgment of the Initial Purchasers, so material and
adverse as to make it impracticable or inadvisable to proceed with the public
offering or the delivery of the Notes and the Guarantees being delivered on the
Closing Date on the terms and in the manner contemplated in the Offering
Memorandum.

          (j) Subsequent to the execution and delivery of this Agreement (i) no
downgrading shall have occurred in the rating accorded the Company's debt
securities by any "nationally recognized statistical rating organization," as
that term is defined by the Commission for purposes of Rule 436(g)(2) under the
Securities Act and (ii) no such organization shall have publicly announced that
it has under surveillance or review, with possible negative implications, its
rating of any of the Company's debt securities.

          (k) Subsequent to the execution and delivery of this Agreement there
shall not have occurred any of the following: (i) trading in securities
generally on the New York Stock Exchange, the American Stock Exchange, the
NASDAQ National Market or the over-the-counter market, or trading in any
securities of the Company on any exchange or in the over-the-counter market
shall have been suspended or materially limited or the settlement of such
trading generally shall have been materially disrupted or minimum prices shall
have been established on any such exchange or such market by the Commission, by
such exchange or by any other regulatory body or governmental authority having
jurisdiction, (ii) a banking moratorium shall have been declared by Federal or
state authorities, (iii) the United States shall have become engaged in
hostilities, there shall have been an escalation in hostilities involving the
United States or there shall have been a declaration of a national emergency or
war by the United States or there shall have occurred any other calamity or
crisis (including, without limitation, as a result of terrorist activities) or
(iv) there shall have occurred such a material adverse change in general
economic, political or financial conditions, including without limitation as a
result of terrorist activities after the date hereof, or the effect of
international conditions on the financial markets in the United States shall be
such, as to make it in the case of (iii) or (iv), in the sole judgment of a
majority in interest of the Representatives, impracticable or inadvisable to
proceed with the public offering or delivery of the Notes being delivered on the
Closing Date on the terms and in the manner contemplated in the Offering
Memorandum.


                                       17



          (l) On or prior to the Closing Date, The Depository Trust Company
shall have accepted the Series A Notes for clearance.

          All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Initial Purchasers.

          9. Indemnification and Contribution.

          (a) The Company and the Guarantors shall jointly and severally
indemnify and hold harmless each Initial Purchaser, its officers and employees
and each person, if any, who controls any Initial Purchaser within the meaning
of the Securities Act, from and against any loss, claim, damage or liability,
joint or several, or any action in respect thereof (including, but not limited
to, any loss, claim, damage, liability or action relating to purchases and sales
of Notes and Guarantees), to which that Initial Purchaser, officer, employee or
controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained (A) in the Preliminary Offering Memorandum, Offering Memorandum
or in any amendment or supplement thereto or (B) in any blue sky application or
other document prepared or executed by the Company (or based upon any written
information furnished by the Company) specifically for the purpose of qualifying
any or all of the Series A Notes under the securities laws of any state or other
jurisdiction (any such application, document or information being hereinafter
called a "Blue Sky Application"), (ii) the omission or alleged omission to state
in the Preliminary Offering Memorandum, Offering Memorandum, or in any amendment
or supplement thereto, or in any Blue Sky Application any material fact required
to be stated therein or necessary to make the statements therein not misleading
or (iii) any act or failure to act or any alleged act or failure to act by any
Initial Purchaser in connection with, or relating in any manner to, the Notes or
the offering contemplated hereby, and which is included as part of or referred
to in any loss, claim, damage, liability or action arising out of or based upon
matters covered by clause (i) or (ii) above (provided that the Company and the
Guarantors shall not be liable under this clause (iii) to the extent that it is
determined in a final judgment by a court of competent jurisdiction that such
loss, claim, damage, liability or action resulted directly from any such acts or
failures to act undertaken or omitted to be taken by such Initial Purchaser
through its gross negligence or willful misconduct), and shall reimburse each
Initial Purchaser and each such officer, employee or controlling person promptly
upon demand for any legal or other expenses reasonably incurred by that Initial
Purchaser, officer, employee or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company and the Guarantors shall not be liable in any such case to the
extent that any such loss, claim, damage, liability or action arises out of, or
is based upon, any untrue statement or alleged untrue statement or omission or
alleged omission made in the Preliminary Offering Memorandum, Offering
Memorandum, or in any such amendment or supplement, or in any Blue Sky
Application, in reliance upon and in conformity with written information
concerning such Initial Purchaser furnished to the Company by or on behalf of
any Initial Purchaser specifically for inclusion therein and provided further,
that the foregoing indemnity agreement with respect to any Preliminary Offering
Memorandum shall not inure to the benefit of any Initial Purchasers who it shall
be established failed to deliver the Offering Memorandum to the person asserting
any losses, claims, damages, liabilities and judgments caused by any untrue
statement or alleged untrue statement of a material fact or an omission or
alleged omission to state a material fact required to be stated in such
Preliminary Offering Memorandum or necessary to make the statements in such
Preliminary Offering Memorandum not misleading, if (A) the Company shall have
furnished copies of the Offering Memorandum to the several Initial Purchasers in
the requisite quantity and sufficiently on a timely basis to permit proper
delivery of the Offering Memorandum to such person; (B) such misstatement or
omission or alleged misstatement or omission was cured in the Offering
Memorandum and the Offering Memorandum was required by law to be delivered to
such person at or prior to the written confirmation of the sale of the Series


                                       18



A Notes to such person and (C) the timely delivery of the Offering Memorandum to
such person would have constituted a valid defense to the losses, claims,
damages, liabilities and judgments asserted by such person. The foregoing
indemnity agreement is in addition to any liability which the Company and the
Guarantors may otherwise have to any Initial Purchaser or to any officer,
employee or controlling person of that Initial Purchaser.

          (b) Each Initial Purchaser, severally and not jointly, shall indemnify
and hold harmless the Company, the Guarantors, their officers and employees,
each of their directors, and each person, if any, who controls the Company and
the Guarantors within the meaning of the Securities Act, from and against any
loss, claim, damage or liability, joint or several, or any action in respect
thereof, to which the Company, the Guarantors or any such director, officer or
controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained (A) in the Preliminary Offering Memorandum, Offering Memorandum
or in any amendment or supplement thereto, or (B) in any Blue Sky Application or
(ii) the omission or alleged omission to state in the Preliminary Offering
Memorandum, Offering Memorandum, or in any amendment or supplement thereto, or
in any Blue Sky Application any material fact required to be stated therein or
necessary to make the statements therein not misleading, but in each case only
to the extent that the untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with written
information concerning such Initial Purchaser furnished to the Company by or on
behalf of that Initial Purchaser specifically for inclusion therein, and shall
reimburse the Company, the Guarantors and any such director, officer or
controlling person for any legal or other expenses reasonably incurred by the
Company, such Guarantor or any such director, officer or controlling person in
connection with investigating or defending or preparing to defend against any
such loss, claim, damage, liability or action as such expenses are incurred. The
foregoing indemnity agreement is in addition to any liability which any Initial
Purchaser may otherwise have to the Company, the Guarantors or any such
director, officer, employee or controlling person.

          (c) Promptly after receipt by an indemnified party under this Section
9 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 9, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 9 except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 9.
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party. After notice from
the indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 9 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, any
indemnified party shall have the right to employ separate counsel in any such
action and to participate in the defense thereof but the fees and expenses of
such counsel shall be at the expense of the indemnified party unless (i) the
employment thereof has been specifically authorized by the indemnifying party in
writing, (ii) such indemnified party shall have been advised by such counsel
that there may be one or more legal defenses available to it which are different
from or additional to those available to the indemnifying party and in the
reasonable judgment of such counsel it is advisable for such indemnified party
to employ separate counsel or (iii) the indemnifying party has failed to assume
the defense of such action and employ counsel reasonably satisfactory to the
indemnified party, in which case, if such indemnified party notifies the
indemnifying party in writing that it elects to employ separate counsel at the
expense of the indemnifying party, the indemnifying party shall not have the
right to assume the defense


                                       19



of such action on behalf of such indemnified party, it being understood,
however, that the indemnifying party shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys (in addition to one local counsel) at any time for all such
indemnified parties, which firm shall be designated in writing by Lehman
Brothers Inc., if the indemnified parties under this Section 9 consist of any
Initial Purchaser or any of their respective officers, employees or controlling
persons, or by the Company, if the indemnified parties under this Section
consist of the Company, the Guarantors or any of the Company's or the
Guarantors' directors, officers, employees or controlling persons. No
indemnifying party shall (i) without the prior written consent of the
indemnified parties (which consent shall not be unreasonably withheld), settle
or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding, or (ii) be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with the consent of the indemnifying party or if there
be a final judgment of the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment.

          (d) If the indemnification provided for in this Section 9 shall for
any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 9(a) or 9(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company and the Guarantors on the one hand and the Initial
Purchasers on the other from the offering of the Series A Notes and the Series A
Guarantees or (ii) if the allocation provided by clause (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 (i) above but also the relative
fault of the Company and the Guarantors on the one hand and the Initial
Purchasers on the other with respect to the statements or omissions which
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations. The relative benefits
received by the Company and the Guarantors on the one hand and the Initial
Purchasers on the other with respect to such offering shall be deemed to be in
the same proportion as the total net proceeds from the offering of the Series A
Notes purchased under this Agreement (before deducting expenses) received by the
Company and the Guarantors, on the one hand, and the total discounts and
commissions received by the Initial Purchasers with respect to the Series A
Notes and the Series A Guarantees purchased under this Agreement, on the other
hand, bear to the total gross proceeds from the offering of the Series A Notes
under this Agreement. The relative fault shall be determined by reference to
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by the
Company, the Guarantors or the Initial Purchasers, the intent of the parties and
their relative knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company, the Guarantors and the Initial
Purchasers agree that it would not be just and equitable if contributions
pursuant to this Section 9(d) were to be determined by pro rata allocation (even
if the Initial Purchasers were treated as one entity for such purpose) or by any
other method of allocation which does not take into account the equitable
considerations referred to herein. The amount paid or payable by an indemnified
party as a result of the loss, claim, damage or liability, or action in respect
thereof, referred to above in this Section shall be deemed to include, for
purposes of this Section 9(d), 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 9(d), no Initial
Purchaser shall be required to contribute any amount in excess of the amount by
which the total price at which the Series A


                                       20



Notes purchased by it was resold to Eligible Purchasers exceeds the amount of
any damages which such Initial Purchaser has otherwise paid or become liable to
pay by reason of any 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 Initial
Purchasers' obligations to contribute as provided in this Section 9(d) are
several in proportion to their respective underwriting obligations and not
joint.

          (e) The Initial Purchasers severally confirm and the Company and the
Guarantors acknowledge that the last paragraph on page ii and the last paragraph
and the fourth to last paragraph under the caption "Plan of Distribution"
constitute the only information concerning such Initial Purchasers furnished in
writing to the Company by or on behalf of the Initial Purchasers specifically
for inclusion in the Offering Memorandum.

          10. Termination. The obligations of the Initial Purchasers hereunder
may be terminated by Lehman Brothers Inc. by notice given to and received by the
Company prior to delivery of and payment for the Series A Notes and the Series A
Guarantees if, prior to that time, any of the events described in Sections 8(i),
8(j) or 8(k), shall have occurred or if the Initial Purchasers shall decline to
purchase the Series A Notes for any reason permitted under this Agreement.

          11. Reimbursement of Initial Purchasers' Expenses. If the Company and
the Guarantors shall fail to tender the Series A Notes and the Series A
Guarantees for delivery to the Initial Purchasers by reason of any failure,
refusal or inability on the part of the Company and the Guarantors to perform
any agreement on its part to be performed, or because any other condition of the
Initial Purchasers' obligations hereunder required to be fulfilled by the
Company and the Guarantors is not fulfilled, the Company and the Guarantors will
reimburse the Initial Purchasers for all reasonable out-of-pocket expenses
(including fees and disbursements of counsel) incurred by the Initial Purchasers
in connection with this Agreement and the proposed purchase of the Series A
Notes and the Series A Guarantees, and upon demand the Company and the
Guarantors shall pay the full amount thereof to the Initial Purchasers.

          12. Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:

          (a) if to the Initial Purchasers, shall be delivered or sent by mail,

                                       21



          Any such statements, requests, notices or agreements shall take effect
at the time of receipt thereof. The Company shall be entitled to act and rely
upon any request, consent, notice or agreement given or made on behalf of the
Initial Purchasers by Lehman Brothers Inc.

          13. Research Independence. In addition, the Company and the Guarantors
acknowledge that the Initial Purchasers' research analysts and research
departments are required to be independent from their respective investment
banking divisions and are subject to certain regulations and internal policies,
and that such Initial Purchasers' research analysts may hold and make statements
or investment recommendations and/or publish research reports with respect to
the Company and the Guarantors and/or the offering that differ from the views of
its investment bankers. The Company and the Guarantors hereby waive and release,
to the fullest extent permitted by law, any claims that the Company or the
Guarantors may have against the Initial Purchasers with respect to any conflict
of interest that may arise from the fact that the views expressed by their
independent research analysts and research departments may be different from or
inconsistent with the views or advice communicated to the Company or the
Guarantors by such Initial Purchasers' investment banking divisions. The Company
and the Guarantors acknowledge that each of the Initial Purchasers is a full
service securities firm and as such from time to time, subject to applicable
securities laws, may effect transactions for its own account or the account of
its customers and hold long or short positions in debt or equity securities of
the companies which may be the subject of the transactions contemplated by this
Agreement.

          14. Persons Entitled to Benefit of Agreement. This Agreement shall
inure to the benefit of and be binding upon the Initial Purchasers, the Company,
the Guarantors and their respective successors. This Agreement and the terms and
provisions hereof are for the sole benefit of only those persons, except that
(A) the representations, warranties, indemnities and agreements of the Company
and the Guarantors contained in this Agreement shall also be deemed to be for
the benefit of the person or persons, if any, who control any Initial Purchaser
within the meaning of Section 15 of the Securities Act and (B) the indemnity
agreement of the Initial Purchasers contained in Section 9(b) of this Agreement
shall be deemed to be for the benefit of directors of the Company and the
Guarantors and any person controlling the Company and the Guarantors within the
meaning of Section 15 of the Securities Act. Nothing in this Agreement is
intended or shall be construed to give any person, other than the persons
referred to in this Section 14, any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision contained herein.

          15. Survival. The respective indemnities, representations, warranties
and agreements of the Company, the Guarantors and the Initial Purchasers
contained in this Agreement or made by or on behalf on them, respectively,
pursuant to this Agreement, shall survive the delivery of and payment for the
Notes and the Guarantees and shall remain in full force and effect, regardless
of any termination or cancellation of this Agreement or any investigation made
by or on behalf of any of them or any person controlling any of them.

          16. Definition of the Terms "Business Day" and "Subsidiary." For
purposes of this Agreement, (a) "business day" means each Monday, Tuesday,
Wednesday, Thursday or Friday which is not a day on which banking institutions
in New York are generally authorized or obligated by law or executive order to
close and (b) "subsidiary" has the meaning set forth in Rule 405 of the rules
and regulations of the Commission under the Securities Act.

          17. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF NEW YORK.
