proposes, subject to the terms and conditions stated herein, to issue and sell to the Underwriters named in Schedule II hereto (the “Underwriters”), for whom you are acting as representatives (the
“Representatives”), the principal amount of its debt securities identified in Schedule I hereto (the “Notes”), to be unconditionally guaranteed by the subsidiaries of the Company identified on Schedule IV hereto
(collectively, the “Guarantors” and, together with the Company, the “Issuers”). The Securities will be issued pursuant to the indenture dated as of August 27, 2001, by and among the Company, the Guarantors
thereunder and The Bank of New York Mellon (formerly The Bank of New York), as trustee (the “Indenture”). The obligations of the Company under the Indenture and the Notes will be unconditionally guaranteed (the

The Issuers have prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities
Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”) a registration statement on Form S-3 (File No. 333-178406), including a prospectus (the “Basic
Prospectus”), relating to debt securities and guarantees thereof to be issued from time to time by the Issuers. The Issuers have also filed with, or transmitted for filing to, or shall promptly hereafter file with or transmit for filing to,

Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (the “Exchange Act”) subsequent to the date of the Underwriting Agreement which are deemed to be incorporated by reference therein. For
purposes of this Agreement, the term “Effective Time” means the effective date of the Registration Statement with respect to the offering of Securities, as determined for the Company pursuant to Section 11 of the Securities Act
and Item 512 of Regulation S-K, as applicable.

of Securities as constituting part of the Time of Sale Information.

matters and shall be responsible for making its own independent investigation and appraisal of the offering of Securities contemplated hereby, and such Underwriters shall have no responsibility or liability to the Company with respect to any
information or advice received by the Company from its own advisors concerning such matters or arising out of its own independent investigation and appraisal of the offering of Securities contemplated hereby. Any review by such Underwriters named in
the Underwriting Agreement of the Company, the transactions contemplated thereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act and (vii) of the receipt by the Company of any notice with respect to any
suspension of the qualification of the Securities for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its reasonable best efforts to prevent the issuance of any such
order suspending the effectiveness of the Registration Statement (as 

  
 15 

 
described in clause (iv) above), preventing or suspending the use of any Preliminary Prospectus or the Prospectus (as described in clause (iv) above) or suspending any such
qualification of the Securities (as described in clause (iv) above) and, if any such order is issued, will obtain as soon as possible the withdrawal thereof. 

(c) The Company will deliver, without charge, to each Underwriter during the Prospectus Delivery Period (as defined
below), as many copies of the Prospectus (including all amendments and supplements thereto) and each Issuer Free Writing Prospectus (if applicable) as the Representatives may reasonably request. As used herein, the term “Prospectus Delivery
Period” means such period of time after the first date of the public offering of the Securities as in the opinion of counsel for the Underwriters a prospectus relating to the Securities is required by law to be delivered (or required to be
delivered but for Rule 172 under the Securities Act) in connection with sales of the Securities by any Underwriter or dealer. 
 (d) Before making, preparing, using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus during the Prospectus Delivery Period, and before filing any amendment or supplement
to the Registration Statement or the Prospectus, the Company will furnish to the Representatives and counsel for the Underwriters, within a reasonable time prior to the filing thereof with the Commission, a copy of the proposed Issuer Free Writing
Prospectus, amendment or supplement for review and will not during the Prospectus Delivery Period make, prepare, use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus or file any such proposed amendment or supplement
(other than any document required to be filed with the Commission under the Exchange Act and incorporated by reference into the Registration Statement or Prospectus) to which the Representatives reasonably objects. 

(e) If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which
the Time of Sale Information as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then
prevailing, not misleading or (ii) it is necessary to amend or supplement the Time of Sale Information to comply with law, the Company will promptly notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above,
file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Time of Sale Information as may be necessary so that the statements in
the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances then prevailing, be misleading or so that the Time of Sale Information will comply with law. 

  
 16 

 (f) If during the Prospectus Delivery Period (i) any event shall occur
or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Company will immediately notify
the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the
Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will
comply with law. 
 (g) The Issuers will arrange for the qualification of the Securities for sale and the
determination of their eligibility for investment under the laws of such states in the United States as the Representatives may reasonably designate and will continue such qualifications in effect so long as reasonably required for the distribution
of the Securities by the Underwriters; provided that in connection therewith none of the Issuers will be required to qualify as a foreign corporation or to file a general consent to service of process in any such state. 

(h) The Company will make generally available to its security holders and the Representatives an earnings statement that
satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the
“effective date” (as defined in Rule 158) of the Registration Statement. 
 (i) During the
period of two years after the Closing Date, none of the Issuers will be or become, an open-end investment company, unit investment trust or face-amount certificate company that is or is required to be registered under Section 8 of the
Investment Company Act. 
 (j) The Company will pay all expenses incidental to the performance of the
Issuers’ obligations under this Agreement and the Indenture including (i) the fees and expenses of the Trustee and its professional advisers; (ii) all expenses in connection with the execution,

  
 17 

 
issue, authentication, packaging and delivery of the Securities, the preparation and printing of this Agreement, the Securities, the Indenture, the Registration Statement, the Preliminary
Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus and amendments and supplements thereto, and any other document relating to the issuance, offer, sale and delivery of the Securities; (iii) the cost
of any advertising approved by the Company in connection with the issue of the Securities, (iv) any expenses (including the reasonable fees and disbursements of counsel) incurred in connection with qualification of the Securities for sale under
the laws of such jurisdictions as the Representatives designate (subject to the limitations set forth in paragraph (g) above) and the printing of memoranda relating thereto, (v) any fees charged by investment rating agencies for the rating
of the Securities, and (vi) expenses incurred in distributing the Time of Sale Information and the Prospectus (including any amendments and supplements thereto) to the Representatives. Unless this Agreement is terminated pursuant to
Section 10, the Company will reimburse the Underwriters for all travel expenses of the Underwriters and the Company’s officers and employees and any other expenses of the Underwriters and the Company in connection with attending or hosting
meetings with prospective purchasers of the Securities. 
 (k) In connection with the offering, until and
including the Business Day following the Closing Date, neither the Issuers nor any of their affiliates have or will, either alone or with one or more other persons, bid for or purchase for any account in which they or any of their affiliates have a
beneficial interest in any Securities or attempt to induce any person to purchase any Securities; and neither they nor any of their affiliates will make bids or purchases for the purpose of creating actual, or apparent, active trading in, or of
raising the price of, the Securities. 
 (l) The Company will not offer, sell, contract to sell, or otherwise
dispose of, directly or indirectly, or file with the Commission a registration statement under the Securities Act relating to, United States dollar-denominated debt securities issued or guaranteed by the Company and having a maturity of more than
one year from the date of issue, other than under any credit facility of the Company, without the prior written consent of the Representatives, which shall not be unreasonably withheld or delayed, for a period beginning at the time of execution of
this Agreement and ending on the Closing Date or the failure of the consummation of the purchase and sale of the Securities as contemplated by Section 3 hereof. 

(m) The Company will file all reports and any definitive proxy or information statements required to be filed by the
Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act during the Prospectus Delivery Period. 

  
 18 

 (n) The Company will retain copies of each Issuer Free Writing Prospectus it
has used that is not filed with the Commission in accordance with, and to the extent provided in Rule 433 under the Securities Act. 
 5. Certain Agreements of the Underwriters. Each Underwriter represents and agrees that: 
 (a) It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus”, as defined in Rule 405 under the Securities Act (which term
includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than (i) a free writing prospectus that,
solely as a result of use by such Underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433, (ii) any Issuer Free Writing Prospectus listed on Schedule III to the Underwriting
Agreement or prepared pursuant to Sections 2(a)(iii), 2(b)(iii) or Section 4(d) above (including any electronic road show), or (iii) any free writing prospectus prepared by such Underwriter and approved by the Company in advance in
writing. 
 (b) Notwithstanding the foregoing the Underwriters may use a term sheet substantially in the form of
Schedule VII to the Underwriting Agreement without the consent of the Company. 
 (c) It will abide by the
offering restrictions as set forth on Schedule VIII hereto. 
 6. Conditions of the Obligations of the Underwriters. The
several obligations of the Underwriters to purchase and pay for the Securities will be subject to the performance by the Issuers of their respective obligations hereunder and to the following additional conditions precedent: 

(a) If a post-effective amendment to the Registration Statement is required to be filed under the Securities Act, such
post-effective amendment shall have become effective, and the Representatives shall have received notice thereof, not later than 5:00 P.M., New York City time, on the date of the Underwriting Agreement; if applicable, the Rule 462(b) Registration
Statement shall have become effective by 10:00 a.m. New York City time on the business day following the date of the Underwriting Agreement; no order suspending the effectiveness of the Registration

Commission; the Prospectus and each Issuer Free Writing Prospectus shall have been timely filed with the Commission under the Securities Act (in the case of an Issuer Free Writing Prospectus, to the extent required by Rule 433 under the Securities
Act) and in accordance with Section 4(a) hereof; and all requests by the Commission for additional information shall have been complied with to the reasonable satisfaction of the Representatives.

organization”, as such term is defined by Section 3(a)(62) of the Exchange Act and (ii) no such organization shall have publicly announced that it has under surveillance or review, or has changed its outlook with respect to, its
rating of the Securities or of any other debt securities or preferred stock of or guaranteed by the Company or the Guarantors, in each case with respect to the Company and the Guarantors, with negative implications of a possible downgrading.

 (d) No event or condition of a type described in Section 2(a)(iv) hereof shall have occurred or shall
exist, which event or condition is not described in the Time of Sale Information (excluding any amendment or supplement thereto) and the Prospectus (excluding any amendment or supplement thereto) and the effect of which in the judgment of the
Representatives makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus. 

(e) Jenner & Block LLP, counsel for the Issuers, shall have furnished to the Representatives, at the request of
the Company, their written opinion and 10b-5 Statement, dated the Closing Date and addressed to the Underwriters, in form and substance reasonably satisfactory to the Representatives, to the effect set forth in Schedule V attached hereto.

  
 20

 (g) The Representatives shall have received on and as of the Closing Date an opinion and 10b-5 Statement of Davis Polk & Wardwell LLP, counsel for the Underwriters, with respect to such matters
as the Representatives may reasonably request, and such counsel shall have received such documents and information as they may reasonably request from the Company to enable them to pass upon such matters. 

(h) No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued
by any federal, state or foreign governmental or regulatory authority that would, as of the Closing Date, prevent the issuance or sale of the Securities; and no injunction or order of any federal, state or foreign court shall have been issued that

 (j) The Representatives shall have received on and as of the Closing Date a certificate of an executive officer of the Company (which certificate shall be executed on behalf of the Company, and not in
such officer’s personal capacity) who has specific knowledge of the Company’s financial matters and is reasonably satisfactory to the Representatives in which such officer, to the best of his or her knowledge after reasonable
investigation, shall (i) confirm that such officer has carefully reviewed the Registration Statement, the Time of Sale Information and the Prospectus and, to the best knowledge of such officer, the representations set forth in Sections 2(a)(i)
and 2(a)(ii) hereof are true and correct, (ii) confirm that the other representations and warranties of the Company in this Agreement are true and correct and that the Company has complied with all agreements and satisfied all conditions on its

business days prior to the Closing Date. 
 The Issuers will furnish the Representatives with such conformed copies of such
opinions, certificates, letters and documents as the Representatives reasonably request. The Representatives may in their sole discretion waive on behalf of the Representatives compliance with any conditions to the obligations of the Representatives
hereunder. 
 7. Indemnification. 

(a) The Issuers agree to indemnify and hold harmless the Underwriters and each person, if any, who controls the
Underwriters within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act against any and all losses, liabilities, claims, damages and expenses as incurred (including but not limited to reasonable
attorneys’ fees and any and all reasonable expenses incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim, and subject to subsection (c) of this Section 7, any and all amounts
paid in settlement of any claim or litigation), to which they or any of them may become subject under the Securities Act, the Exchange Act or any other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses,
liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or caused by any omission
or alleged omission to state therein a material fact required to be 

  
 22 

 
stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus
(or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading, in each case under clause (i) or (ii) except insofar as such losses, claims, damages liabilities or expenses arise out of, or are based upon, any untrue statement or omission
or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein.

 (b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Issuers, their
respective directors and officers and each person, if any, who controls any of the Issuers within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all losses, liabilities, claims, damages
and expenses as incurred (including but not limited to reasonable attorney’s fees and any and all reasonable expenses incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim, and subject
to subsection (c) of this Section 7, any and all amounts paid in settlement of any claim or litigation), to which they or any of them may become subject under the Securities Act, the Exchange Act or any other federal or state statutory law
or regulation, at common law or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or action in respect thereof) arise out of or are based upon, any untrue statement or omission or alleged untrue statement or omission made
in reliance upon and in conformity with any information relating to such Underwriter furnished to the Issuers in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any
amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed that the only such information consists of the information identified in the Underwriting Agreement as being
provided by the Underwriters. The Issuers acknowledge that the information identified as “Underwriter Information” on Schedule I hereto constitutes the only information furnished in writing by the Underwriters or the Representatives
expressly for use in the Prospectus, or any amendment or supplement thereto, as the case may be. 
 (c) Promptly
after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made

  
 23 

 
against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the commencement of such action (but the failure so to notify an
indemnifying party shall not relieve it from any liability which it may have under this Section 7). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein, and to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof
with counsel reasonably satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall
be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying
parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) such indemnified party or parties shall have been advised by counsel that there
may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on
behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties. In no event shall the indemnifying party or parties be liable for fees and expenses of more than one counsel (in
addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or
circumstances. The indemnifying party shall indemnify and hold harmless the indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action (iv) effected with its
written consent or (v) effected without its written consent if (1) the settlement is entered into more than 20 business days after the indemnifying party shall have received a request from the indemnified party for reimbursement for the
fees and expenses of counsel (in any case where such fees and expenses are at the expense of the indemnifying party), (2) such indemnifying party shall have received notice of the terms of such settlement at least 20 business days prior to such
settlement being entered into and (3) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. Notwithstanding the immediately preceding sentence, if at any
time an indemnified party shall 

  
 24 

 have requested an indemnifying party to reimburse the indemnified party for fees and
expenses of counsel (in any case where such fees and expenses are at the expense of the indemnifying party), an indemnifying party shall not be liable for any settlement of the nature contemplated by this Section 7(c) effected without its
consent if such indemnifying party (vi) reimburses such indemnified party in accordance with such request to the extent that it considers such request to be reasonable and (vii) provides written notice to the indemnified party
substantiating the unpaid balance as unreasonable, in each case prior to the date of such settlement. 
 8. Contribution.
In order to provide for contribution in circumstances in which the indemnification provided for in Section 7 hereof is for any reason held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified
thereunder, the Issuers and the Underwriters shall contribute to the aggregate losses, claims, damages, liabilities and expenses of the nature contemplated by such indemnification provision (including any reasonable investigation, legal and other
expenses incurred in connection with, and, subject to the last sentence of this Section 8, any amount paid settlement of, any action, suit or proceeding or any claims asserted, but after deducting in the case of losses, claims, damages,
liabilities and expenses suffered by the Issuers any contribution received by the Issuers from persons, other than the Underwriters, who may also be liable for contribution, including persons who control any of the Issuers within the meaning of
Section 15 of the Securities Act or Section 20(a) of the Exchange Act) as incurred to which the Issuers and the Underwriters may be subject, in such proportions as is appropriate to reflect the relative benefits received by the Issuers and
the Underwriters from the offering of the Securities or, if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the
Issuers and the Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the
Issuers and the Underwriters shall be deemed to be in the same proportion as (x) the total proceeds from the offering (net of discounts and commissions but before deducting expenses) received by the Company and (y) the discounts and
commissions received by the Underwriters, respectively, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Issuers and of the Underwriters 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 Issuers or the Underwriters and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or omission or any violation of the nature referred to in Section 7(a). The Issuers and the Underwriters agree that it would not be just and equitable if contribution
pursuant to this Section 8 were determined by pro rata allocation or by any other method of 

  
 25 

 
allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 8, (a) in no case shall the Underwriters be
liable or responsible for any amount in excess of the discount applicable to the Securities purchased by the Underwriters hereunder, and (b) 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. Notwithstanding the provisions of this Section 8 and the preceding sentence, the Underwriters shall not be required to
contribute any amount in excess of the amount by which the total price at which the Securities purchased by it and resold exceeds the amount of any damages that it has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. For purposes of this Section 8, each person, if any, who controls the Underwriters within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act shall have the
same rights to contribution as the Underwriters, and each person, if any, who controls any of the Issuers within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act, shall have the same rights to
contribution as the Issuers, subject in each case to clauses (a) and (b) of this Section 8. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party
in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties
from whom contribution may be sought from any obligation it or they may have under this Section 8 or otherwise. No party shall be liable for contribution with respect to any action or claim settled without its written consent; provided,
however, that such consent was not unreasonably withheld. 
 9. Termination. This Agreement may be terminated in the
absolute discretion of the Representatives, by written notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (a) trading generally shall have been suspended or materially limited on the New
York Stock Exchange or the over-the-counter market; (b) trading of any securities issued or guaranteed by the Company shall have been suspended on the New York Stock Exchange; (c) a general moratorium on commercial banking activities shall
have been declared by federal or New York State authorities; (d) there shall have occurred a material disruption in commercial banking or securities settlement or clearing services; or (e) there shall have occurred any outbreak or
escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States; provided that, in the case of clauses (d) and (e) above, the occurrence of such event is, in the
judgment of the Representatives, material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale
Information and the Prospectus. 

  
 26 

 10. Defaulting Underwriter. (a) If, on the Closing Date, any Underwriter
defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the
terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours
within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non
defaulting Underwriters or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration
Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. 

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or
Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed 10% of the aggregate principal amount of all the
Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the
principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made. 

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or
Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds 10% of the aggregate principal amount of all the Securities,
or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this
Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 4(j) hereof and except that the provisions of Section 7 and
Section 8 hereof shall not terminate and shall remain in effect. 

  
 27 

 (d) Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default. 
 (e)
As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in the Underwriting Agreement that, pursuant to this Section 10, purchases
Securities that a defaulting Underwriter agreed but failed to purchase. 
 11. Survival of Certain Representations and
Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Issuers or their officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect,
regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriters, the Issuers or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of
and payment for the Securities. If for any reason the purchase of the Securities by the Underwriters is not consummated, the Issuers shall remain responsible for their own expenses to be paid or reimbursed by it pursuant to Section 4(j) and the
respective obligations of the Issuers and the Underwriters pursuant to Sections 7 and 8 shall remain in effect. If the purchase of the Securities by the Underwriters is not consummated for any reason other than solely because of the occurrence of
any event specified in clause (a), (c), (d) or (e) of Section 9, and other than as a result of the termination of this Agreement pursuant to Section 10, the Company will reimburse the Underwriters for all out-of-pocket expenses
(including fees and disbursements of counsel) reasonably incurred by it in connection with the offering of the Securities. 

12. Notices. All communications hereunder will be in writing and, if sent to the Underwriters will be mailed, delivered or
telegraphed and confirmed to the Representatives at the address appearing in Schedule I hereto, or, if sent to the Issuers, will be mailed, delivered or telegraphed and confirmed to the Company at 2941 Fairview Park Drive, Suite 100, Falls Church,

 OPINION OF JENNER & BLOCK LLP 

[                    ],
20[        ] 
 [The Representatives] 
 as representatives of the several Underwriters 
 party to the Underwriting Agreement 

Ladies and Gentlemen: 
 We are
issuing this letter in our capacity as special counsel for General Dynamics Corporation (the “Corporation”) in response to the requirement of Section 6(e) of the Underwriting Agreement dated
[                    ], 20[    ] (the “Underwriting Agreement”) by and among the Corporation, the guarantors
named therein (the “Guarantors” and, together with the Corporation, the “Issuers”) and [the Representatives], as representatives of the several Underwriters party thereto (the “Representatives”).
The Underwriting Agreement relates to the offering (the “Offering”) of certain [Title of Debt Securities], including the guarantees of the Guarantors related thereto (the “Securities”). Every term which is defined
or given a special meaning in the Underwriting Agreement and which is not given a different meaning in this letter has the same meaning whenever it is used in this letter as the meaning it is given in the Underwriting Agreement. 

In connection with the preparation of this letter, we have among other things read: 

(a) the Registration Statement on Form S-3 (Registration No. 333-178406) filed by the Corporation with the Securities and Exchange
Commission (the “Commission”) for the purpose of registering the Offering under the Securities Act of 1933, as amended (the “Securities Act”) (which registration statement, as amended and including the information
incorporated therein by reference and the information deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430B under the Securities Act, and as constituted at the Effective Time, is herein called the
“Registration Statement”); 
 (b) the Prospectus of the Corporation dated December 8, 2008 (the
“Basic Prospectus”) and the Preliminary Prospectus Supplement thereto dated [            ], 20[         ] (which Basic Prospectus
and Preliminary Prospectus Supplement, including the information incorporated therein by reference, are herein collectively called the “Preliminary Prospectus”); 

  
 V-1

 (c) the Basic Prospectus and the Prospectus Supplement thereto dated
[            ], 20[            ] (which Basic Prospectus and Prospectus Supplement, including the information incorporated
therein by reference, are herein collectively called the “Prospectus”); 
 (d) the reports filed by the
Corporation pursuant to the Exchange Act and incorporated by reference into the Preliminary Prospectus and the Prospectus; 

(e) the Indenture, dated as of August 27, 2001 (the “Indenture”) by and among the Corporation, the Guarantors and
The Bank of New York Mellon (formerly The Bank of New York), as trustee (the “Trustee”), and the [            ] Supplemental Indenture thereto, dated as of
[            ], 20[            ] (the “[            ]
Supplemental Indenture”); 
 (f) an executed copy of the Underwriting Agreement; 

(g) a specimen of the Securities; 
 (h) a copy of the resolutions of the Board of Directors of the Corporation adopted on [            ] 

(i) a copy of the resolutions of the Board of Directors of each of the Guarantors adopted on
[            ]; 
 (j) a copy of the Restated Certificate of
Incorporation of the Corporation, as amended, certified as of a recent date by the Secretary of State of Delaware; 
 (k) a copy
of the Amended and Restated By-laws of the Corporation, as amended; and 
 (l) copies of all certificates and other documents
delivered today in connection with the consummation of the Offering. 
 Subject to the assumptions, qualifications and
limitations which are identified in this letter, we advise you that: 
 (i) (A) The Registration Statement is an
“automatic shelf registration statement” as defined under Rule 405 of the Securities Act that has been filed with the Commission not earlier than three years prior to the date hereof; (B) (i) to our knowledge no notice of
objection of the Commission to the use of such registration statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act has been received by the Company and (ii) the Indenture was qualified under the
Trust Indenture Act; (C) each of the Preliminary Prospectus and the Prospectus was filed with the Commission pursuant to Rule 424(b) 

  
 V-2

 
under the Securities Act; and (D) to our knowledge no order suspending the effectiveness of the Registration Statement has been issued, no notice of objection of the Commission to the use of
such registration statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act has been received by the Company and no proceeding for that purpose or pursuant to Section 8A of the Securities Act against
the Company or in connection with the offering has been initiated or threatened by the Commission. 
 (ii) the
Corporation is validly existing as a corporation in good standing under the laws of the State of Delaware, with corporate power and authority to own its properties and conduct its business as described in the Registration Statement, the Time of Sale
Information and the Prospectus; 
 (iii) (A) (1) the Indenture has been duly authorized, executed and
delivered by the Issuers; (2) the Securities have been duly authorized, executed and delivered by the Issuers; (3) the Indenture and the Securities, assuming due authentication, execution and delivery thereof by the Trustee and receipt of
consideration by the Corporation therefore as contemplated by the Underwriting Agreement, constitute valid and legally binding obligations of the Issuers enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles (regardless of whether such enforceability is considered in a proceeding in equity or at
law), including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing; and (B) the Indenture and the Securities conform in all material respects to the description thereof contained in the Time of Sale
Information and the Prospectus; 
 (iv) the Underwriting Agreement has been duly authorized, executed and
delivered by the Issuers; 
 (v) the execution, delivery and performance of the Indenture and the Underwriting
Agreement and the issuance and sale of the Securities and the compliance by the Corporation with all of the provisions thereof and the consummation by the Corporation of the transactions contemplated therein on the Closing Date will not conflict
with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument set forth on Schedule A attached hereto (but no
opinion is expressed as to compliance with any financial tests or cross default provisions in any such agreement or other document), except where such conflict, breach, violation or default is not

  
 V-3

 
reasonably likely to have a material adverse change in the condition (financial or otherwise), financial position, stockholders’ equity or results of operations of the Corporation and its
subsidiaries, considered as one enterprise, nor will such action result in any violation of the provisions of the Certificate of Incorporation or By-laws (each as amended) of any of the Issuers or any statute or any order, rule or regulation known
to such counsel of any court or governmental agency or body having jurisdiction over the Issuers or any of their properties (but no opinion is expressed in this paragraph as to compliance with any disclosure requirement or any prohibition against
fraud or misrepresentation or as to whether performance of the indemnification or contribution provisions in the Underwriting Agreement would be permitted); and each of the Issuers has the corporate power and authority to authorize, issue and sell
the Securities as contemplated by the Underwriting Agreement; 
 (vi) the execution, delivery and performance of
the Indenture and the Underwriting Agreement on the Closing Date and the issuance and sale of the Securities and the compliance by the Guarantors with all of the provisions thereof and the consummation by the Guarantors of the transactions
contemplated therein on the Closing Date will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or
instrument set forth on Schedule A attached hereto (but no opinion is expressed as to compliance with any financial tests or cross default provisions in any such agreement or other document), except where such conflict, breach, violation or default
is not reasonably likely to have a material adverse change in the condition (financial or otherwise), financial position, stockholders’ equity or results of operations of the Corporation and its subsidiaries, considered as one enterprise;

 (vii) no consent, approval, authorization, order, decree, registration or qualification of or with any such
court or governmental agency or body is required for the issuance and sale of the Securities or the consummation by the Issuers of the transactions contemplated by the Underwriting Agreement, except for the qualification of the Indenture under the
Trust Indenture Act; 
 (viii) the statements set forth in the Basic Prospectus under the caption
“Description of the Debt Securities” and the statements set forth in the Preliminary Prospectus Supplement and the Prospectus Supplement under the caption “Description of the Notes and Guarantees” and “Certain U.S. Federal
Tax Consequences,” in each case insofar as such statements constitute summaries of the legal matters, documents or proceedings referred to therein, fairly present in all material respects the information called for with respect to such legal
matters, documents and proceedings; 

  
 V-4

 (ix) the documents incorporated by reference in the Registration Statement,
the Time of Sale Information and the Prospectus or any further amendment or supplement thereto made by the Issuers prior to the Closing Date (other than the financial statements and related notes and schedules and other financial and statistical
data included or incorporated by reference therein or omitted therefrom, as to which we express no opinion), when they became effective or were filed with the Commission, as the case may be, and as amended if such a document has been amended,
appeared on their face to be responsive in all material respects with the requirements of the Exchange Act and the rules and regulations thereunder; 
 (x) the Registration Statement, as of the Effective Time, and each Issuer Free Writing Prospectus included in the Time of Sale Information and the Prospectus, as of the date of the Prospectus Supplement
and as of the date of this letter (other than the financial statements and related notes and schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which we express no opinion), appeared on their
face to be responsive in all material respects to the requirements of Form S-3; and 
 (xi) none of the Issuers
is an “investment company,” as such term is defined in the Investment Company Act. 
  
 ••••••••• 
 The purpose of our
professional engagement was not to establish factual matters, and the preparation of the Registration Statement, the Time of Sale Information and the Prospectus involved many determinations of a wholly or partially nonlegal character. Except to the
extent otherwise explicitly indicated in numbered paragraph (viii) above, we make no representation that we have independently verified the accuracy, completeness or fairness of the Registration Statement, the Time of Sale Information or the
Prospectus or that the actions taken in connection with the preparation of the Registration Statement, the Time of Sale Information or the Prospectus (including the actions described in the next paragraph) were sufficient to cause the Prospectus,
the Time of Sale Information or the Registration Statement to be accurate, complete or fair. We are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the Time of Sale Information, the Prospectus or
the Registration Statement, except to the extent otherwise explicitly indicated in numbered paragraph (viii) above. 

  
 V-5

 We have participated in the preparation of the Registration Statement, the Time of Sale
Information and the Prospectus. During the course of such preparation, we examined various documents, including those listed at the beginning of our letter, and participated in various conferences with representatives and counsel of the Corporation,
with representatives of the independent accountants for the Corporation and representatives of and counsel to the Underwriters, at which conferences the contents of the Registration Statement, the Time of Sale Information and the Prospectus (and the
documents incorporated therein by reference) were reviewed and discussed. 
 Based on our participation in the conferences and
discussions identified above, our understanding of applicable law and the experience that we have gained in the practice thereunder and relying as to factual matters to the extent we deem appropriate upon the representations and statements of
officers and other representatives of the Corporation, we advise you that no fact came to our attention to cause us to conclude that (i) the Registration Statement, as of the Effective Time, contained an 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, (ii) the Time of Sale Information, at the Time of Sale, contained an untrue statement of a material fact or omitted 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 or (iii) the Prospectus, as of its date, or as of the date of this letter, contained or
contains an 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, except for, in each case,
financial statements and schedules and other financial and statistical and similar data and information included therein or incorporated by reference therein or omitted therefrom, as to which we express no opinion. 

 
 •••••••••

 Except for the activities described in the immediately preceding section of this letter, we have not undertaken any
investigation to determine the facts upon which the advice in this letter is based. 
 We have assumed for purposes of this
letter: each document we have reviewed for purposes of this letter is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, and all signatures on each such
document are genuine; that the Underwriting Agreement and every other agreement we have examined for purposes of this letter constitutes a valid and binding obligation of each party to that document and that each such party has satisfied all legal
requirements that are applicable to such party to the extent necessary to entitle such party to enforce such agreement (except that we make no such assumption with respect to the 

  
 V-6

 
Corporation or the Guarantors); and that you have acted in good faith and without notice of any fact which has caused you to reach any conclusion contrary to any of the advice provided in this
letter. We have also made other assumptions which we believe to be appropriate for purposes of this letter. 
 In preparing this
letter we have relied without independent verification upon: (i) information contained in certificates obtained from governmental authorities; (ii) factual information represented to be true in the Underwriting Agreement, in the other
documents specifically identified at the beginning of this letter as having been read by us and in the certificates and other documents executed by the Corporation and the Guarantors and delivered to you or to the trustee under the Indenture in
connection with the consummation of the Offering; (iii) numbered paragraphs 1 and 5 of the opinion of Gregory S. Gallopoulos, Senior Vice President and General Counsel of the Corporation, with respect to the Offering; (iv) factual
information provided to us by the Corporation or its representatives; and (v) factual information we have obtained from such other sources as we have deemed reasonable. We have assumed that there has been no relevant change or development
between the dates as of which the information cited in the preceding sentence was given and the date of this letter and that the information upon which we have relied is accurate and does not omit disclosures necessary to prevent such information
from being misleading. 
 We confirm that we do not have knowledge that has caused us to conclude that our reliance and
assumptions cited in the two immediately preceding paragraphs are unwarranted. Whenever this letter provides advice about (or based upon) our knowledge of any particular information or about any information which has or has not come to our attention
such advice is based entirely on the conscious awareness at the time this letter is delivered on the date it bears by the lawyers with Jenner & Block LLP at that time who have engaged in substantive representation of the Corporation in
connection with (i) the Offering and (ii) the preparation and filing of reports required to be filed with the Commission by the Corporation pursuant to the Exchange Act and incorporated by reference into the Registration Statement or the
Prospectus. 
 Our advice on every legal issue addressed in this letter is based exclusively on the internal law of the State of
New York, the General Corporation Law of the State of Delaware or the federal law of the United States, and represents our opinion as to how that issue would be resolved were it to be considered by the highest court in the jurisdiction which enacted
such law. With respect to our opinions above, we have assumed, with your permission, that the laws of states of Maine, Nevada and Virginia are the same as the laws of the State of Delaware. Our opinions are limited to the specific issues addressed.
None of the opinions or other advice contained in this letter considers or covers: (i) any foreign or state securities (or “blue sky”) laws or regulations; (ii) any financial statements or supporting schedules (or any
notes to any such statements or 

  
 V-7

 
schedules) or other financial information set forth or incorporated by reference in (or omitted from) the Registration Statement, the Time of Sale Information or the Prospectus; (iii) any
rules and regulations of the Financial Industry Regulatory Authority (FINRA) relating to the compensation of Underwriters; or (iv) the rules and regulations of the New York Stock Exchange, LLC or any other relevant securities exchange. This
letter does not cover any other laws, statutes, governmental rules or regulations or decisions which in our experience are not usually considered for or covered by opinions like those contained in this letter or are not generally applicable to
transactions of the kind covered by the Underwriting Agreement. 
 This letter speaks as of the time of its delivery on the date
it bears. We do not assume any obligation to provide you with any subsequent opinion or advice by reason of any fact about which we did not have knowledge at that time, by reason of any change subsequent to that time in any law, other governmental
requirement or interpretation thereof covered by any of our opinions or advice, or for any other reason. 
 This letter may be
relied upon by the Underwriters only for the purpose served by the provision in the Underwriting Agreement cited in the initial paragraph of this letter in response to which it has been delivered. Without our written consent: (i) no person
other than the Underwriters may rely on this letter for any purpose (except that the Trustee may rely upon paragraph (ii) of this letter in connection with the performance of its obligations under the Indenture to the same extent as if this
letter had been addressed to the Trustee); (ii) this letter may not be cited or quoted in any financial statement, prospectus, private placement memorandum or other similar document; (iii) this letter may not be cited or quoted in any
other document or communication which might encourage reliance upon this letter by any person or for any purpose excluded by the restrictions in this paragraph; and (iv) copies of this letter may not be furnished to anyone for purposes of
encouraging such reliance.

 [                    ], 20[        ] 

[The Representatives] 
 as representatives of the
several Underwriters party 
 to the Underwriting Agreement 
 Ladies and Gentlemen: 
 I am the Senior Vice President and General Counsel of
General Dynamics Corporation, a Delaware corporation (the “Company”), and I have acted as legal counsel in connection with that Underwriting Agreement by and among the Company, the Guarantors named therein and [Name of
Representatives] dated [                    ], 20[        ] (the “Underwriting Agreement”).
This opinion is being delivered pursuant to Section 6(f) of the Underwriting Agreement. Initially capitalized terms not defined herein have the meanings assigned to them in the Underwriting Agreement. 

In arriving at the opinions expressed below, I am familiar with, and either I or those under my supervision have examined the following
documents, in each case including the documents incorporated by reference therein: the Registration Statement, the Time of Sale Information and the Prospectus. 
 I have also made such investigations of law, relied as to factual matters on such other documents and instruments and reviewed information or held such conferences with officers and employees of the
Company, as I have deemed appropriate. As to any fact material to my opinion, I have (with your permission and without any investigation or independent confirmation) assumed the accuracy of such instruments, certificates and documents with respect
to the facts stated therein. In rendering the opinion that follows, I have assumed and not verified (i) the genuineness of the signatures of persons signing all documents and instruments in connection with which this opinion is rendered other
than on behalf of the Company and the Guarantors, (ii) the authority of such persons signing all documents on behalf of the parties thereto other than the Company and the Guarantors, (iii) the authenticity of all documents submitted to us
as originals, (iv) the conformity to the original documents of all documents submitted to us as copies, (v) that all documents which must be executed and delivered by parties other than the Company and the Guarantors to be effective have
been duly authorized, executed and delivered by such other parties and (vi) that the Notes have been fully paid for. 
 In
clauses 1, 3 and 4 below, I have relied exclusively upon certificates or other documents from public officials as to the matters stated in such documents and certificates and such opinion is not intended to provide any conclusion or assurance beyond
that conveyed by such document or certificate. 

  
 VI-1

 Based on the foregoing and subject to the assumptions, qualifications and limitations as may
be set forth below, it is my opinion that: 
 1. each of the Guarantors has been duly incorporated or organized and is validly
existing and in good standing under the laws of its jurisdiction of incorporation or organization; 
 2. all of the issued
shares of capital stock or limited liability company interests, as applicable, of each Guarantor have been duly and validly authorized and issued, are fully paid and non-assessable and (except for directors’ qualifying shares) are owned
directly or indirectly by the Company, free and clear of all encumbrances, equities or claims; 
 3. the Company has been duly
qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification, except where the
failure to be so qualified would not result in a material adverse change in the condition (financial or otherwise), financial position, stockholders’ equity or results of operations of the Company and its subsidiaries, considered as one
enterprise; 
 4. each of the Guarantors has been duly qualified as a foreign corporation (or other organization) for the
transaction of business and is in good standing under the laws of each jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification, except where the failure to be so qualified would not result in a
material adverse change in the condition (financial or otherwise), financial position or results of operations of the applicable Guarantor; and 
 5. to the best of my knowledge after reasonable investigation, neither the Company nor any Guarantor is (a) in violation of its Certificate of Incorporation or By-laws, as amended, or other
organizational documents, as applicable, or (b) in default in the performance or observance of any obligation, agreement, covenant or condition contained in any material indenture, mortgage, deed of trust, loan agreement, or lease or agreement
or other material instrument to which it is a party or by which it or any of its properties may be bound, where such default is reasonably expected by the Company to have a material adverse change in the condition (financial or otherwise), financial
position, stockholders’ equity or results of operations of the Company and its subsidiaries, considered as one enterprise. 

  
 VI-2

 Although I have not independently verified and am not passing upon and do not assume any
responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Information and the Prospectus, no information has come to my attention that leads me to believe that (i) the
Registration Statement, as of the Effective Time, contained an 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, (ii) the Time of
Sale Information, at the Time of Sale, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading,
or (iii) the Prospectus, as of its date, or as of the date of this letter, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading, except for, in each case, financial statements and schedules and other financial and statistical and similar data and information included therein or incorporated by reference therein or
omitted therefrom, as to which I express no opinion. 
 I am a member of the Bar of the State of Illinois and am qualified as
Corporate Counsel Registrant in the State of Virginia. This opinion is limited to the Delaware General Corporation Law, the internal law of the State of Illinois and the federal securities laws of the United States, and I express no opinion as to
the laws of any other jurisdiction. I know that the Underwriting Agreement is stated to be governed by the laws of the State of New York. However, for purposes of rendering the opinion, I have assumed, with your permission, that the Underwriting
Agreement is stated to be governed by the laws of the State of Illinois. My opinions are limited to the specific issues addressed and are limited in all respects to laws and facts existing on the date hereof. By rendering my opinions, I do not
undertake to advise you of any changes in such laws, or facts that may occur after the date hereof. 
 This opinion is furnished
only for your benefit and may not be relied upon by any other person or entity, nor may copies be delivered or disclosed to any other person or entity, without my prior written consent. 

Very truly yours, 
 Gregory S. Gallopoulos 
 Senior Vice President and General
Counsel

 ARTICLE 1 
 DEFINITIONS 
 (a) Capitalized terms used herein and not otherwise
defined herein shall have the respective meanings ascribed thereto in the Base Indenture. 
 (b) The rules of interpretation set
forth in the Base Indenture shall be applied hereto as if set forth in full herein. 
 (c) For all purposes of this Seventh
Supplemental Indenture, except as otherwise expressly provided or unless the context otherwise requires, the following terms shall have the following respective meanings (such meanings shall apply equally to both the singular and plural forms of the
respective terms). 
 “Comparable Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker 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 the Notes. 
 “Comparable Treasury Price”
means, with respect to any Redemption Date for the Notes, the average of four Reference Treasury Dealer Quotations obtained by the Trustee for that applicable Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer
Quotations, or, if the Trustee obtains fewer than four Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations obtained by the Trustee. 
 “Guarantors” means, initially, American Overseas Marine Company, LLC, a Delaware limited liability company, Bath Iron Works Corporation, a Maine corporation, Electric Boat Corporation, a
Delaware corporation, General Dynamics Armament and Technical Products, Inc., a Delaware corporation, General Dynamics Government Systems Corporation, a Delaware corporation, General Dynamics Land Systems Inc., a Delaware corporation, General
Dynamics Ordnance and Tactical Systems, Inc., a Virginia corporation, Gulfstream Aerospace Corporation, a Delaware corporation, and National Steel and Shipbuilding Company, a Nevada corporation. 

“Independent Investment Banker” means one of the Reference Treasury Dealers, to be appointed by the Company. 

“Notes” shall have the meaning ascribed thereto in the recitals hereof. 

“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 3:30
p.m., New York City time, on the third Business Day preceding the Redemption Date.

LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBS Securities Inc. and Wells Fargo Securities, LLC; and (ii) one other primary U.S. Government securities dealer (a “Primary Treasury Dealer”) chosen by the

in its place another nationally recognized investment banking firm that is a Primary Treasury Dealer. 
 “Remaining
Scheduled Payments” means, with respect to each Note that the Company is redeeming, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related Redemption Date if such Note were not
redeemed. However, if the Redemption Date is not a scheduled interest payment date with respect to that Note, the amount of the next succeeding scheduled interest payment on that Note will be deemed to be reduced by the amount of interest accrued on
such Note to the Redemption Date. 
 “Treasury Rate” means, with respect to any Redemption Date, the rate per
annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for
that Redemption Date. The Treasury Rate will be calculated on and as of the third Business Day immediately preceding the Redemption Date.

 CERTIFICATE OF AUTHENTICATION 

This is one of the Securities of the series designated as the Notes due 2017 herein referred to in the within-mentioned Indenture.

  

							
	Dated:                     	 		 	THE BANK OF NEW YORK MELLON,
as Trustee
				
		 		 	By:	 	  

		 		 		 	Authorized Signatory
		 		 		 	

 (FORM OF REVERSE OF NOTE DUE 2017) 

This Note is one of a duly authorized series of Notes of the Company (herein sometimes referred to as the “Notes”), all
issued or to be issued under and pursuant to an Indenture dated as of August 27, 2001, duly executed and delivered by and among the Company, the Guarantors named therein and The Bank of New York Mellon, as trustee (the
“Trustee”), as supplemented to date, including by the Seventh Supplemental Indenture dated as of November 6, 2012, by and among the Company, the Guarantors named therein and the Trustee (the Indenture, as so supplemented, the
“Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, the
Guarantors named therein and the Holders of the Notes. By the terms of the Indenture, the Notes are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Indenture. This series of
Notes is initially offered in aggregate principal amount as specified in said Seventh Supplemental Indenture. 
 The Company at
its option may, at any time and from time to time, redeem the Notes, in whole or in part, upon payment of a redemption price (the “Redemption Price”) equal to the greater of (i) 100% of the principal amount of the Notes to be
redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months), at the Treasury Rate plus 10 basis
points. The Redemption Price for the Notes will include accrued but unpaid interest, if any, on the principal amount of the Notes being redeemed to but excluding the Redemption Date. On and after the Redemption Date, interest will cease to accrue on
the Notes or any portion thereof called for redemption, unless the Company defaults in the payment of the Redemption Price and accrued interest. 
 Any redemption pursuant to the preceding paragraph will be made upon not less than 30 nor more than 60 days’ prior notice before the Redemption Date to the Holders, at the Redemption Price. If the
Notes are only partially redeemed, the Notes to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem fair and appropriate; provided, that if at the time of redemption the Notes are registered as Global Securities,
the Depository shall determine, in accordance with its procedures, the principal amount of such Notes held by each Holder of Notes to be redeemed. The Redemption Price shall be paid prior to 12:00 noon, New York time, on the Redemption Date or such
earlier time as the Company determines, provided that the Company shall deposit with the Trustee an amount sufficient to pay the Redemption Price by 10:00 a.m., New York time, on the date such Redemption Price is to be paid. 

 In the event of redemption of this Note in part only, a new Note or Notes of this series for
the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 In case an Event
of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Notes may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture. 
 The Indenture contains provisions permitting the Company and the Trustee, with the consent of the
Holders of not less than a majority in aggregate principal amount of the Notes of each series affected at the time outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Notes; provided, however, that no such supplemental indenture shall, among other
things, (i) change the fixed maturity of any Notes of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, without
the consent of the Holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of each Note then
outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Notes of any series at the time outstanding affected thereby, on behalf of all of the Holders of the
Notes of such series, to waive any past default in the performance of any of the covenants contained in the Indenture, or established pursuant to the Indenture with respect to such series, and its consequences, except a default in the payment of the
principal of or premium, if any, or interest on any of the Notes of such series. Any such consent or waiver by the registered Holder (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future
Holders and owners of this Note and of any Note issued in exchange therefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation
of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the time and place and at the rate and in the money herein prescribed. 

As provided in the Indenture and subject to certain limitations therein set forth, this Note is transferable by the registered Holder
hereof on the Security Register of the Company, upon surrender of this Note for registration of transfer 

 
at the office or agency of the Trustee in the City and State of New York accompanied by a written instrument or instruments of transfer in form satisfactory to the Company or the Trustee duly
executed by the registered Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of authorized denominations and for the same aggregate principal amount and series will be issued to the designated transferee
or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto. 

Prior to due presentment for registration of transfer of this Note, the Company, the Trustee, any paying agent and the Security Registrar
may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Security Registrar) for the purpose
of receiving payment of or on account of the principal hereof and premium, if any, and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Security Registrar shall be affected by any
notice to the contrary. 
 No recourse shall be had for the payment of the principal of, premium, if any, or the interest on
this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past, present or future, as such, of the Company or any Guarantor or of
any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the
consideration for the issuance hereof, expressly waived and released. 
 The Notes of this series are issuable only in
registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 above that amount. This Global Note is exchangeable for Notes in definitive form only under certain limited circumstances set forth in the Indenture. As
provided in the Indenture and subject to certain limitations herein and therein set forth, Notes of this series so issued are exchangeable for a like aggregate principal amount of Notes of this series of a different authorized denomination, as
requested by the Holder surrendering the same. 
 All terms used in this Note that are defined in the Indenture shall have the
meanings assigned to them in the Indenture. 
 THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN THE INDENTURE AND THIS
NOTE WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS THEREOF.

 (FORM OF REVERSE OF NOTE DUE 2022) 

This Note is one of a duly authorized series of Notes of the Company (herein sometimes referred to as the “Notes”), all
issued or to be issued under and pursuant to an Indenture dated as of August 27, 2001, duly executed and delivered by and among the Company, the Guarantors named therein and The Bank of New York Mellon, as trustee (the
“Trustee”), as supplemented to date, including by the Seventh Supplemental Indenture dated as of November 6, 2012, by and among the Company, the Guarantors named therein and the Trustee (the Indenture, as so supplemented, the
“Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, the
Guarantors named therein and the Holders of the Notes. By the terms of the Indenture, the Notes are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Indenture. This series of
Notes is initially offered in aggregate principal amount as specified in said Seventh Supplemental Indenture. 
 The Company at
its option may, at any time and from time to time, redeem the Notes, in whole or in part, upon payment of a redemption price (the “Redemption Price”) equal to the greater of (i) 100% of the principal amount of the Notes to be
redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months), at the Treasury Rate plus 12.5 basis
points; provided that if the Company redeems any Notes on or after August 15, 2022 (three months prior to the maturity date of the Notes), the Redemption Price for those Notes will equal 100% of the principal amount of the Notes to be redeemed.
The Redemption Price for the Notes will include accrued but unpaid interest, if any, on the principal amount of the Notes being redeemed to but excluding the Redemption Date. On and after the Redemption Date, interest will cease to accrue on the
Notes or any portion thereof called for redemption, unless the Company defaults in the payment of the Redemption Price and accrued interest. 
 Any redemption pursuant to the preceding paragraph will be made upon not less than 30 nor more than 60 days’ prior notice before the Redemption Date to the Holders, at the Redemption Price. If the
Notes are only partially redeemed, the Notes to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem fair and appropriate; provided, that if at the time of redemption the Notes are registered as Global Securities,
the Depository shall determine, in accordance with its procedures, the principal amount of such Notes held by each Holder of Notes to be redeemed. The Redemption Price shall be paid prior to 12:00 noon, New York time, on the Redemption Date or such
earlier time as the Company determines, provided that the Company shall deposit with the Trustee an amount sufficient to pay the Redemption Price by 10:00 a.m., New York time, on the date such Redemption Price is to be paid. 

 In the event of redemption of this Note in part only, a new Note or Notes of this series for
the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 In case an Event
of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Notes may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture. 
 The Indenture contains provisions permitting the Company and the Trustee, with the consent of the
Holders of not less than a majority in aggregate principal amount of the Notes of each series affected at the time outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Notes; provided, however, that no such supplemental indenture shall, among other
things, (i) change the fixed maturity of any Notes of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, without
the consent of the Holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of each Note then
outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Notes of any series at the time outstanding affected thereby, on behalf of all of the Holders of the
Notes of such series, to waive any past default in the performance of any of the covenants contained in the Indenture, or established pursuant to the Indenture with respect to such series, and its consequences, except a default in the payment of the
principal of or premium, if any, or interest on any of the Notes of such series. Any such consent or waiver by the registered Holder (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future
Holders and owners of this Note and of any Note issued in exchange therefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation
of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the time and place and at the rate and in the money herein prescribed. 

 As provided in the Indenture and subject to certain limitations therein set forth, this Note
is transferable by the registered Holder hereof on the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Trustee in the City and State of New York accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company or the Trustee duly executed by the registered Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of authorized denominations and
for the same aggregate principal amount and series will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto. 
 Prior to due presentment for registration of transfer of this Note, the
Company, the Trustee, any paying agent and the Security Registrar may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon
made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any
paying agent nor any Security Registrar shall be affected by any notice to the contrary. 
 No recourse shall be had for the
payment of the principal of, premium, if any, or the interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past,
present or future, as such, of the Company or any Guarantor or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released. 
 The Notes of this series are issuable only in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 above that amount. This Global Note is exchangeable for Notes

 All terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture. 

 THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN THE INDENTURE AND THIS NOTE WITHOUT
REGARD TO CONFLICT OF LAW PROVISIONS THEREOF.

 (FORM OF REVERSE OF NOTE DUE 2042) 

This Note is one of a duly authorized series of Notes of the Company (herein sometimes referred to as the “Notes”), all
issued or to be issued under and pursuant to an Indenture dated as of August 27, 2001, duly executed and delivered by and among the Company, the Guarantors named therein and The Bank of New York Mellon, as trustee (the
“Trustee”), as supplemented to date, including by the Seventh Supplemental Indenture dated as of November 6, 2012, by and among the Company, the Guarantors named therein and the Trustee (the Indenture, as so supplemented, the
“Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, the
Guarantors named therein and the Holders of the Notes. By the terms of the Indenture, the Notes are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Indenture. This series of
Notes is initially offered in aggregate principal amount as specified in said Seventh Supplemental Indenture. 
 The Company at
its option may, at any time and from time to time, redeem the Notes, in whole or in part, upon payment of a redemption price (the “Redemption Price”) equal to the greater of (i) 100% of the principal amount of the Notes to be
redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months), at the Treasury Rate plus 15 basis
points; provided that if the Company redeems any Notes on or after May 15, 2042 (six months prior to the maturity date of the Notes), the Redemption Price for those Notes will equal 100% of the principal amount of the Notes to be redeemed. The
Redemption Price for the Notes will include accrued but unpaid interest, if any, on the principal amount of the Notes being redeemed to but excluding the Redemption Date. On and after the Redemption Date, interest will cease to accrue on the Notes
or any portion thereof called for redemption, unless the Company defaults in the payment of the Redemption Price and accrued interest. 
 Any redemption pursuant to the preceding paragraph will be made upon not less than 30 nor more than 60 days’ prior notice before the Redemption Date to the Holders, at the Redemption Price. If the
Notes are only partially redeemed, the Notes to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem fair and appropriate; provided, that if at the time of redemption the Notes are registered as Global Securities,
the Depository shall determine, in accordance with its procedures, the principal amount of such Notes held by each Holder of Notes to be redeemed. The Redemption Price shall be paid prior to 12:00 noon, New York time, on the Redemption Date or such
earlier time as the Company determines, provided that the Company shall deposit with the Trustee an amount sufficient to pay the Redemption Price by 10:00 a.m., New York time, on the date such Redemption Price is to be paid. 

 In the event of redemption of this Note in part only, a new Note or Notes of this series for
the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 In case an Event
of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Notes may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture. 
 The Indenture contains provisions permitting the Company and the Trustee, with the consent of the
Holders of not less than a majority in aggregate principal amount of the Notes of each series affected at the time outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Notes; provided, however, that no such supplemental indenture shall, among other
things, (i) change the fixed maturity of any Notes of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, without
the consent of the Holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of each Note then
outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Notes of any series at the time outstanding affected thereby, on behalf of all of the Holders of the
Notes of such series, to waive any past default in the performance of any of the covenants contained in the Indenture, or established pursuant to the Indenture with respect to such series, and its consequences, except a default in the payment of the
principal of or premium, if any, or interest on any of the Notes of such series. Any such consent or waiver by the registered Holder (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future
Holders and owners of this Note and of any Note issued in exchange therefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation
of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the time and place and at the rate and in the money herein prescribed. 

 As provided in the Indenture and subject to certain limitations therein set forth, this Note
is transferable by the registered Holder hereof on the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Trustee in the City and State of New York accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company or the Trustee duly executed by the registered Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of authorized denominations and
for the same aggregate principal amount and series will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto. 
 Prior to due presentment for registration of transfer of this Note, the
Company, the Trustee, any paying agent and the Security Registrar may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon
made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any
paying agent nor any Security Registrar shall be affected by any notice to the contrary. 
 No recourse shall be had for the
payment of the principal of, premium, if any, or the interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past,
present or future, as such, of the Company or any Guarantor or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released. 
 The Notes of this series are issuable only in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 above that amount. This Global Note is exchangeable for Notes
in definitive form only under certain limited circumstances set forth in the Indenture. As provided in the Indenture and subject to certain limitations herein and therein set forth, Notes of this series so issued are exchangeable for a like
aggregate principal amount of Notes of this series of a different authorized denomination, as requested by the Holder surrendering the same. 
 All terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture. 

 THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN THE INDENTURE AND THIS NOTE WITHOUT
REGARD TO CONFLICT OF LAW PROVISIONS THEREOF.
