(a) Underwriting Agreement. This Agreement has been duly authorized, executed and delivered by such Forward Purchaser and, at the Closing Date and at each Additional Closing Date, such Forward Purchaser will have the full right, power and authority to sell, transfer and deliver the Borrowed Securities.

(b) Authorization of the Forward Agreement. The applicable Forward Agreement has been duly authorized, executed and delivered by such Forward Purchaser and constitutes a valid and binding obligation of such Forward Purchaser, enforceable against such Forward Purchaser accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally and except as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).

(c) Right to Transfer. Such Forward Purchaser will, at the Closing Date and at each Additional Closing Date, have the free and unqualified right to transfer the Borrowed Securities to be sold by such Forward Purchaser hereunder, free and clear of any security interest, mortgage, pledge, lien, charge, claim, equity or encumbrance of any kind; and upon delivery of such Borrowed Securities and payment of the purchase price therefor as herein contemplated, assuming each of the Underwriters has no notice of any adverse claim, each of the Underwriters will have the free and unqualified right to transfer the Borrowed Securities purchased by it from such Forward Purchaser, free and clear of any security interest, mortgage, pledge, lien, charge, claim, equity or encumbrance of any kind.

4. Further Agreements of the Company. The Company covenants and agrees with each Underwriter that:

(a) Filing of the Prospectus. The Company will file the final Prospectus with the Commission within the time periods specified by Rule 424(b) and Rule 430A under the Securities Act and will file promptly 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 subsequent to the date of the Prospectus and for so long as the delivery of a prospectus is required in connection with the offering or sale of the Shares; and the Company will furnish copies of the Prospectus to the Underwriters in New York City prior to 10:00 A.M., New York City time, on the business day next succeeding the date of this Agreement in such quantities as the Representatives may reasonably request.

(b) Delivery of Copies. The Company will deliver, without charge, (i) to the Representatives, three signed copies of the Registration Statement as originally filed and each amendment thereto, in each case including all exhibits and consents filed therewith and documents incorporated by reference therein; and (ii) to each Underwriter (A) a conformed copy of the Registration Statement as originally filed and each amendment thereto (without exhibits) and (B) during the Prospectus Delivery Period, as many copies of the Prospectus (including all amendments and supplements thereto and documents incorporated by reference therein) 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 Shares as in the opinion of counsel for the Underwriters a prospectus relating to the Shares is required by law to be delivered in connection with sales of the Shares by any Underwriter or dealer.

(c) Amendments or Supplements. 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 a copy of the proposed amendment or supplement for review and will not file any such proposed amendment or supplement to which the Representatives reasonably objects.

(d) Notice to the Representatives. The Company will advise the Representatives promptly, and confirm such advice in writing, (i) when any amendment to the Registration Statement has been filed or becomes effective; (ii) when any supplement to the Prospectus or any amendment to the Prospectus has been filed; (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (iv) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or the Prospectus or the initiation or threatening of any proceeding for that purpose; (v) of the occurrence of any event within the Prospectus Delivery Period 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 a material fact 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; and (vi) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Shares for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary

Prospectus or the Prospectus or suspending any such qualification of the Shares and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

(e) Ongoing Compliance of the Prospectus. 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 an untrue statement of a material fact or omit to state a 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.

(f) Blue Sky Compliance. The Company will qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request and will continue such qualifications in effect so long as required for distribution of the Shares; provided that the Company shall not be required to (i) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject.

(g) Earning Statement. The Company will make generally available to its security holders and the Representatives as soon as practicable an earning 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.

(h) Clear Market. For a period of 90 days after the date of the initial public offering of the Shares, the Company will not without the prior written consent of the Representatives (i) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any shares of Stock or any securities convertible into or exercisable or exchangeable for Stock or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Stock or such other securities, in cash or otherwise, without the prior written consent of the Representatives, other than (1) the Shares to be sold hereunder, (2) the issuance of shares of Common Stock by the Company to each Forward Purchaser under the applicable Forward Agreement, (3) the issuance of shares of Common Stock in connection with a 5% Common Stock dividend, and (4) any shares of Common Stock of the Company issued under the Company’s existing stock based plans or upon the exercise of options granted under existing employee stock option plans.

(i) Use of Proceeds. The Company will apply the net proceeds from the sale of the Shares as described in the Prospectus under the heading “Use of Proceeds”.

(j) No Stabilization. The Company will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Shares.

(k) Exchange Listing. The Company will use its best efforts to list, subject to notice of issuance, the Company Shares on the New York Stock Exchange (the “Exchange”).

(l) Reports. So long as the Shares are outstanding, the Company will furnish to the Representatives, as soon as they are available, copies of all reports or other communications (financial or other) furnished to holders of the Shares, and copies of any reports and financial statements furnished to or filed with the Commission or any national securities exchange or automatic quotation system.

5. Conditions of Underwriters’ Obligations.

Subsequent to the execution and delivery of this Agreement, no event or condition of a type described in Section 3(e) hereof shall have occurred or shall exist, which event or condition is not described in 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 Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement and the Prospectus.

(e) Officer’s Certificate. The Representatives shall have received on and as of the Closing Date or the Additional Closing Date, as the case may be, a certificate of the chief financial officer or chief accounting officer of the Company and one additional senior executive officer of the Company who is satisfactory to the Representatives (i) confirming that such officers have carefully reviewed the Registration Statement and the Prospectus and, to the best knowledge of such officers, the representation set forth in Section 3(b) hereof is true and correct, (ii) confirming 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 part to be performed or satisfied hereunder at or prior to such Closing Date and (iii) to the effect set forth in paragraphs (a), (c) and (d) above.

The Representatives shall have received on and as of the Closing Date or the Additional Closing Date, as the case may be, an opinion of ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇, 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 to enable them to pass upon such matters.

(k) No Legal Impediment to Issuance.

6. Indemnification and Contribution.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each Forward Purchaser and each person, if any, who controls any Forward Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, in each case, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus (or any amendment or supplement thereto) or any Preliminary Prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities 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 through the Representatives or such Forward Purchaser, furnished to the Company in writing by such Underwriter or Forward Purchaser as the case may be, expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter or Forward Purchaser consists of the information described as such in subsection (b) below; provided that the Company will not be liable to any Underwriter with respect to any Prospectus to the extent that the Company shall sustain the burden of proving that any such loss, liability, claim, damage or expense resulted from the fact that such Underwriter in contravention of a requirement of this Agreement or applicable law, sold Shares to a person to whom such Underwriter failed to send or give, at or prior to the Closing Date, a copy of the Prospectus, as then amended or supplemented if: (i) the Company has previously furnished copies thereof (sufficiently in advance of the Closing Date to allow for distribution by the Closing Date) to the Underwriter and the loss, liability, claim, damage or expense of such Underwriter resulted from an untrue statement or omission of a material fact contained in or omitted from the Preliminary Prospectus which was corrected in the Prospectus as, if applicable, amended or supplemented prior to the Closing Date and such Prospectus was required by law to be delivered at or prior to the written confirmation of sale to such person and (ii) such failure to give or send such Prospectus by the Closing Date to the party or parties asserting such loss, liability, claim, damage or expense would have constituted the sole defense to the claim asserted by such person.

(b) Indemnification of the Company and the Forward Purchasers. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each Forward Purchaser and each person, if any, who controls any Forward Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, in each case, to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that 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 Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement and the Prospectus (or any amendment or supplement thereto) or any Preliminary Prospectus, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the first paragraph under the caption “Underwriting — Commissions and Discounts,” the information contained in the first and second paragraphs under the caption “Underwriting — Price Stabilization and Short Positions” and the information contained in the paragraph under the caption “Underwriting — Passive Market Making”.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 6 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 6. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 6 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying

Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any reasonably required local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by ▇.▇. ▇▇▇▇▇▇ Securities Inc., any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company and any such separate firm for any Forward Purchaser, its affiliates directors and officers and any control persons of such Forward Purchaser shall be designated in writing by ▇▇ ▇▇▇▇▇▇ or MLI, as the case may be. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company (which benefits shall include the proceeds to be received by the Company pursuant to the Forward Agreements) on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Shares (which benefits shall include the proceeds to be received by the Company

pursuant to the Forward Agreements) and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Shares. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 6, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 6 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

7. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

8. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company and the Forward Purchasers, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Shares, prior to the Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange, the American Stock Exchange, the National Association of Securities Dealers, Inc., the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) 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, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement and the Prospectus.

9. Defaulting Underwriter. (a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares 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 Shares, 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 Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date or the Additional Closing Date, as the case may be, 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. 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 Schedule I hereto that, pursuant to this Section 9, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares 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 Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Shares on the Additional Closing Date, as the case may be, shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 9 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 10 hereof and except that the provisions of Section 6 hereof shall not terminate and shall remain in effect.

Annex A-1

[Form of Opinion of Counsel for the Company]

(a) The Registration Statement was declared effective under the Securities Act as of the date and time specified in such opinion; the Prospectus was filed with the Commission pursuant to the subparagraph of Rule 424(b) under the Securities Act specified in such opinion on the date specified therein; and no order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose is pending or, to the knowledge of such counsel, threatened by the Commission.

(b) The Company and each of the Company’s subsidiaries identified on Attachment I hereto (the “Subsidiaries”) have been duly organized and are validly existing and in good standing under the laws of the State of Delaware, are duly qualified to do business and are in good standing in each jurisdiction identified opposite its name on Attachment II hereto, which the Company has advised such counsel are the only jurisdictions in which their respective ownership or leasing of property or the conduct of their respective businesses requires such qualification, and have all power and authority necessary to own or hold their respective properties and to conduct the businesses in which they are engaged, except where the failure to be so qualified or have such power or authority would not, individually or in the aggregate, have a material adverse effect on the business, properties, management, financial position, stockholders’ equity, results of operations or prospects of the Company and its subsidiaries taken as a whole ( a “Material Adverse Effect”).

(c) The Company has an authorized capitalization as set forth in the Prospectus under the heading “Description of Southern Union’s Common Stock and Preferred Stock — General”; all the outstanding shares of capital stock of the Company (including the shares to be borrowed and sold by the Forward Purchasers) have been duly issued and validly authorized and to the knowledge of such counsel after due inquiry are fully paid and non-assessable; the capital stock of the Company conforms in all material respects to the description thereof contained in the Registration Statement and the Prospectus; and all necessary actions under the limited liability company act or the limited partnership act under which each Subsidiary was organized and the Subsidiary’s constituent documents have been taken for the purchase of such subsidiary’s equity interests.

(d) This Agreement has been duly authorized, executed and delivered by the Company.

(e) Each of the Forward Agreements has been duly authorized, executed and delivered by the Company and constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms; and the Forward Agreements conform in all material respects to the descriptions thereof in the Prospectus.

(f) The Shares to be issued and sold by the Company hereunder have been duly authorized, and when delivered to and paid for by the Underwriters in accordance with the terms of

this Agreement, will be validly issued, fully paid and non-assessable and the issuance of the Shares is not subject to any preemptive or similar rights.

(g) The Shares to be purchased by the Forward Purchasers from the Company pursuant to the Forward Agreements, whether pursuant to physical settlement, net stock settlement, as a result of acceleration of the Forward Agreements or otherwise, have been duly authorized and reserved for issuance and, when issued and delivered by the Company to the Forward Purchasers pursuant to the Forward Agreements against payment of the consideration set forth in the Forward Agreements, will be validly issued and fully paid and non-assessable and no holder of such Shares is or will be subject to personal liability by reason of being such a holder.

(h) In reliance upon the SEC Staff Interpretation of Section 5 of the Securities Act set forth in the no-action letter captioned ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co. (available October 9, 2003), the issuance and sale of the Shares by the Company to the Forward Purchasers in settlement of the Forward Agreements in accordance with the terms thereof will not require registration under the Securities Act and the Forward Purchasers will not have an obligation to deliver a Prospectus in connection with the Shares delivered to them by the Company upon such settlements, assuming that (i) Prospectuses were delivered by the Underwriters in connection with sales of Shares in an amount equal to the Base Amount (as defined in the Forward Agreements), and (ii) the Forward Purchasers only deliver the Shares to close out open borrowings created in the course of the hedging activities created by the Forward Purchasers relating to their exposure under the Forward Agreements in compliance with the Forward Agreements.

(i) No consent, approval, authorization, order, registration or qualification of or with any court or arbitrator or governmental or regulatory authority is required for the execution, delivery and performance by the Company of this Agreement and each of the Forward Agreements, the issuance and sale of the Shares being delivered on the Closing Date or the Additional Closing Date, as the case may be, and compliance by the Company with the terms thereof and the consummation of the transactions contemplated hereby and each of the Forward Agreements, except for (i) the registration of the Shares under the Securities Act and (ii) such consents, approvals, authorizations, orders and registrations or qualifications as may be required under applicable state securities laws or with respect to regulatory matters, as to which such counsel need express no opinion.

(j) The execution, delivery and performance by the Company of this Agreement and each of the Forward Agreements, the issuance and sale of the Shares being delivered on the Closing Date, and the compliance by the Company with the terms of, and the consummation of the transactions contemplated by this Agreement and the Forward Agreements will not (i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its Subsidiaries pursuant to, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument listed as an exhibit in the Company’s Annual Report on Form 10-K for the year ended June 30, 2003 or in any report subsequently filed by the Company pursuant to Section 13(a) or 15(d) of the Exchange Act or the Company’s Third Amended and Restated Revolving Credit Agreement, dated as of May 28, 2004, (ii) result in any violation of the provisions of the charter or by-laws or similar organizational documents of

the Company or any of its subsidiaries or (iii) result in the violation of any law or statute or any judgment, order or regulation of any court or arbitrator or governmental or regulatory authority of the District of Columbia or the United States of America (other than the blue sky laws of the various states as to which such counsel need express no opinion) except, in the case of clauses (i) and (iii) above, for such conflict, breach or violation that would not, individually or in the aggregate, have a Material Adverse Effect.

(k) The statements in the Prospectus under the headings (i) “Underwriting” and “Description of Southern Union’s Common Stock and Preferred Stock” and (ii) “Business — Transportation and Storage Segment—Regulation,” and, to our knowledge after due inquiry, “Business — Distribution Segment—Regulation and Rates,” “Business – Environmental” and “Legal Proceedings,” in the case of clause (ii) above, incorporated by reference from Items 1 and 3 of Part I of the Company’s Annual Report on Form 10-K for the year ended June 30, 2003, and Item 1 of Part II of the Company’s Quarterly Reports on Form 10-Q for the periods ended September 30, 2003, December 31, 2003 and March 31, 2004, to the extent that they constitute summaries of the terms of stock, matters of law or legal conclusions, fairly summarize the matters described therein in all material respects; and, to the knowledge of such counsel after due inquiry, (A) there are no current or pending legal, governmental or regulatory actions, suits or proceedings that are required under the Securities Act to be described in the Prospectus and that are not so described and (B) there are no statutes, regulations or contracts and other documents that are required under the Securities Act to be filed as exhibits to the Registration Statement or described in the Prospectus and that have not been so filed or described.

(l) The Company is not and, after giving effect to the offering and sale of the Shares and the application of the proceeds thereof as described in the Prospectus, will not be an “investment company” within the meaning of the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission thereunder (collectively, “Investment Company Act”) that is required to be registered under the Investment Company Act.

(m) Neither the Company nor any of its subsidiaries is a “holding company” or, to the knowledge of such counsel after due inquiry, a “subsidiary company” of a holding company or an “affiliate” thereof within the meaning of the Public Utility Holding Company Act of 1935, as amended.

(n) Such counsel has no reason to believe that (i) any document filed pursuant to the Exchange Act and incorporated by reference in the Registration Statement and the Prospectus (other than financial statements and related schedules therein, as to which such counsel need express no belief) did not comply when so filed as to form in all material respects with the Exchange Act and the rules and regulations of the Commission thereunder and (ii) the Registration Statement and Prospectus (other than financial statements and other financial information contained therein, as to which such counsel need express no belief) do not comply as to form in all material respects with the Securities Act and the applicable rules and regulations of the Commission thereunder (other than the omission of certain historical and pro forma information relating to Panhandle at the time the Registration Statement was declared effective).

Such counsel shall also state that they have participated in conferences with representatives of the Company and with representatives of its independent accountants and counsel at which conferences the contents of the Registration Statement and the Prospectus and any amendment and supplement thereto and related matters were discussed and, although such counsel has not undertaken to determine independently and such counsel is not passing on and assume no responsibility for the accuracy, completeness or fairness of the Registration Statement, the Prospectus and any amendment or supplement thereto (except as expressly provided above), nothing has come to the attention of such counsel to cause such counsel to believe that the Registration Statement, at the time of its effective date and at the date of the Underwriting Agreement, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading (other than the financial statements and other financial information contained therein, as to which such counsel need express no belief), or that the Prospectus or any amendment or supplement thereto as of its date and the Closing Date contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (other than the financial statements and other financial information contained therein, as to which such counsel need express no belief).

Such counsel may state that whenever its opinion is based on factual matters that are to its “knowledge after due inquiry” such counsel has relied, as to factual matters, exclusively on the representation and warranties of the Company set forth in this Agreement (after discussion of the contents thereof with the Company) or certificates of others as to the existence or nonexistence of the factual matters upon which such opinion is predicated. Such counsel shall state that it has no reason to believe, however, that any such certificate is untrue or inaccurate in any material respect.

Such counsel may state that in addition to the limitations and qualifications set forth above, the enforceability of the obligations of the Company under the Forward Agreements is subject to the effect of any applicable bankruptcy (including, without limitation, fraudulent conveyance and preference), insolvency, reorganization, rehabilitation, moratorium or similar laws and decisions relating to or affecting the enforcement of creditors’ rights generally and to general principles of equity (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 the possible unavailability of specific performance or injunctive relief. Such principles are of general application, and in applying such principles a court, among other things, might, might decline to order the Company to perform covenants. Further, such counsel need not express an opinion with respect to the enforceability of provisions in the Forward Agreements with respect to waiver, delay, extension or omission of notice or enforcement of rights or remedies, waivers of defenses or waivers of benefits of stay, extension, moratorium, redemption, statutes of limitations or other nonwaivable benefits provided by operation of law. Further, such counsel may state that the enforceability of any exculpation, indemnification or contribution provisions contained in the Forward Agreements may be limited by applicable law or public policy.

In rendering such opinions, such counsel may state that they express no opinion as to the laws of any jurisdiction other than the relevant federal law of the United States of America, District of Columbia law and the Delaware General Corporation Law and, with respect to the opinion expressed in paragraph (b) only, the Delaware Limited Liability Company Act and the Delaware Revised Uniform Limited Partnership Act, insofar as such laws apply, and that they render no opinion with respect to the state securities or blue sky laws of any jurisdiction or the law of any other jurisdiction. Such counsel may note that they are not admitted to the practice of law in the states of Delaware, Massachusetts, Pennsylvania or Rhode Island. With respect to paragraph (j), such counsel may also state that they render no opinion with respect to the anti-fraud provisions of the federal securities laws.
