(x) The Company has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15 and 15d-

15 under the Exchange Act); such disclosure controls and procedures are designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s Chief Executive Officer and its Chief Financial Officer by others within those entities, particularly during the period in which reports under the Exchange Act are being prepared, and based on management’s most recent evaluation of such disclosure controls and procedures as described in the Company’s Form 10-Q for the period ended March 31, 2006, such disclosure controls and procedures are functioning effectively to provide reasonable assurance that the information required to be disclosed by the Company in reports filed under the Exchange Act is (i) recorded, processed, summarized and reported within the time period specified in the Commission’s rules and forms and (ii) accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate , to allow timely decisions regarding disclosure; the Company’s auditors and the Audit Committee of the Board of Directors have been advised of: (i) any significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting which are reasonably likely to adversely affect the Company’s ability to record, process, summarize, and report financial data; and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal controls over financial reporting.

(y) The Company has provided you true, correct, and complete copies of all documentation pertaining to any extension of credit in the form of a personal loan made, directly or indirectly, by the Company to any director or executive officer of the Company, or to any family member or affiliate of any director or executive officer of the Company; and since July 30, 2002, the Company has not, directly or indirectly, including through any subsidiary: (i) extended credit, arranged to extend credit, or renewed any extension of credit, in the form of a personal loan, to or for any director or executive officer of the Company, or to or for any family member or affiliate of any director or executive officer of the Company; or (ii) made any material modification, including any renewal thereof, to any term of any personal loan to any director or executive officer of the Company, or any family member or affiliate of any director or executive officer, which loan was outstanding on July 30, 2002.

2. PURCHASE, SALE AND DELIVERY OF THE SHARES.

(a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Company agrees to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a net purchase price of $21.496 per share (representing the public offering price of $22.310 per share less underwriting discounts and commissions of $0.814 per share), the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereof, subject to adjustments in accordance with Section 9 hereof and subject, in each case, to adjustments among the Underwriters as the Representative in its sole discretion shall make to eliminate any sales or purchases of fractional shares.

(b) Payment for the Firm Shares to be sold hereunder is to be made in Federal (same day) funds to an account designated by the Company against delivery of the Firm Shares therefor to the Representatives for the several accounts of the Underwriters. Such payment and delivery are to be made through the facilities of The Depository Trust Company, New York New York (“DTC”) at 10:00 a.m., New York time, on June 12, 2006 or at such other time and date not later than five business days thereafter as you and the Company shall agree upon, such time and date being herein referred to as the “Closing Date.”

(c) In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the several Underwriters to purchase the Option Shares at the price per share as set forth in the first paragraph of this Section 2. No Option Shares shall be sold or delivered by the Underwriters unless the Firm Shares previously have been, or simultaneously with the Option Shares are, sold and delivered. The option granted hereby may be exercised in whole or in part by giving written notice (i) at any time before the Closing Date and (ii) only once thereafter within 30 days after the date of this Agreement, by you, as the Representative of the several Underwriters, to the Company setting forth the number of Option Shares as to which the several Underwriters are exercising the option and the time and date at which such Option Shares are to be delivered. The time and date at which the Option Shares are to be delivered shall be determined by the Representative but shall not be earlier than three full business days after written notice of the exercise of such option, nor in any event prior to the Closing Date (such time and date being herein referred to as the “Option Closing Date”). If the date of exercise of the option is three or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. The number of Option Shares to be purchased by each Underwriter shall

be in the same proportion to the total number of Option Shares being purchased as the number of Firm Shares being purchased by such Underwriter bears to the total number of Firm Shares, adjusted by you in such manner as to avoid fractional shares. The option with respect to the Option Shares granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters. You, as Representatives of the Underwriters, may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Company. To the extent, if any, that the option is exercised, payment for the Option Shares shall be made on the Option Closing Date in Federal (same day) funds to an account designated by the Company for the Option Shares against delivery of the Option Shares through the facilities of DTC.

3. OFFERING BY THE UNDERWRITERS.

It is understood that the several Underwriters are to make a public offering of the Firm Shares as soon as the Representative deems it advisable to do so. The Firm Shares are to be initially offered to the public at the public offering price set forth in the Prospectus. The Representative may from time to time thereafter change the public offering price and other selling terms. To the extent, if at all, that any Option Shares are purchased pursuant to Section 2 hereof, the Underwriters will offer them to the public on the foregoing terms.

It is further understood that you will act as the Representative for the Underwriters in the offering and sale of the Shares in accordance with a Master Agreement Among Underwriters entered into by you and the several other Underwriters.

4. COVENANTS OF THE COMPANY.

The Company will also advise the Representative promptly of the filing of any such amendment or supplement and of the institution by the Commission of any stop order proceedings in respect of the Registration Statement or of any part thereof and will use its best efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued.

(c) The Company will cooperate with the Representative in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representative may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent. The Company will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Representative may reasonably request for distribution of the Shares.

(d) The Company will deliver to, or upon the order of, the Representative, from time to time, as many copies of the Prospectus as the Representative may reasonably request.

(e) If, at any time when a prospectus relating to the Shares is required by law to be delivered (whether physically or through compliance with Rule 172 under the Act) in connection with sales of the Shares by any

Underwriter or dealer, any event occurs 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 any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend or supplement the Prospectus to comply with the Act, the Company promptly will either (i) prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus or (ii) prepare and file with the Commission an appropriate filing under the Exchange Act which shall be incorporated by reference in the Prospectus so that the Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus will comply with the law.

(i) Notwithstanding paragraph (h) above, if (i) during the last 15 calendar days plus 3 business days of the 90-day lock-up period the Company issues an earnings release or material news or a material event relating to the Company occurs or (ii) prior to the expiration of the 90-day lock-up period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day lock up period, then the restrictions described above will continue to apply until the expiration of the 15 calendar days plus 3 business days beginning on the issuance of the earnings release or the occurrence of the material news or material event.

(j) The Company shall apply the net proceeds of its sale of the Shares as set forth in the Prospectus.

default or omission of any Underwriter, the Company shall reimburse the several Underwriters for reasonable out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred in connection with investigating, marketing and proposing to market the Shares or in contemplation of performing their obligations hereunder; but the Company shall not in any event be liable to any of the several Underwriters for damages on account of loss of anticipated profits from the sale by them of the Shares.

(v) To such counsel’s knowledge, the Company is not an “ineligible issuer” (as defined in Rule 405 under the Act) as of the date of the filing of the Registration Statement.

(vi) The statements in the Pre-Pricing Prospectus and the Prospectus under the caption “Description of Capital Stock”, insofar as such statements constitute a summary of documents referred to therein or matters of law, fairly summarize in all material respects the information called for with respect to such documents and matters.

(vii) Such counsel does not know of any contracts or documents required to be filed as exhibits to or incorporated by reference in the Registration Statement or described in the Registration Statement, the Pre-Pricing Prospectus, if applicable, or the Prospectus which are not so filed, incorporated by reference or described as required, and to counsel’s knowledge, such contracts and documents as are summarized in the Registration Statement or the Prospectus are fairly summarized in all material respects.

(ix) The execution and delivery of this Agreement and the consummation of the transactions herein contemplated do not and will not violate or result in a breach of any of the terms or provisions of, or constitute a default under, (A) the Charter or By-Laws of the Company, (B) any material indenture, mortgage, deed of trust or other material agreement or instrument to which the Company or any of the Subsidiaries is a party or by which the Company or any of the Subsidiaries may be bound and which has been filed by the Company as an exhibit to a filing under the Exchange Act, and which is known to such counsel or (C) laws of Pennsylvania or any U.S. federal law that in such counsel’s experience, are generally applicable to transactions in the nature of those contemplated by this Agreement, except that such counsel need express no opinion regarding any federal securities laws, or any state securities or “blue sky” laws or Section 8 of this Agreement.

In rendering such opinion ▇▇▇▇▇▇ ▇▇▇▇▇ may rely as to matters governed by the laws of states other than Pennsylvania or Federal laws on local counsel in such jurisdictions, provided that in each case ▇▇▇▇▇▇ ▇▇▇▇▇ shall state that they believe that they and the Underwriters are justified in relying on such other counsel. In addition to the foregoing opinions, such counsel shall advise you supplementally that such counsel has participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company and representatives of the Underwriters and their counsel, at which conferences the contents of the Registration Statement, the Pre-Pricing Prospectus, the Prospectus and the Permitted Free Writing Prospectuses listed on Schedule C hereto were discussed and, although such counsel is not passing upon and does not assume responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Pre-Pricing Prospectus, the Prospectus or any Permitted Free Writing Prospectus listed on Schedule C hereto, on the basis of the foregoing and the information disclosed to such counsel, but without independent check and verification, and relying as to materiality on representations and statements of officers and other representatives of the Company, such counsel will confirm to you that no fact has come to the attention of those lawyers in such firm that participated in the preparation of the Registration Statement and the Prospectus that has led them to believe that (i) the Registration Statement, as of the Effective Time, 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, (ii) the Prospectus, as of the date of the Prospectus Supplement and at the initial time of purchase of the Firm Shares by the Underwriters, and each time of purchase of the Option Shares by the Underwriters, as the case may be, contained (or contains) 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, in light of the circumstances under which they were made, not misleading or (iii) the Disclosure Package, as of 4:30 pm New York City Time on June 7,

2006, when considered together with the pricing information set forth in Schedule A hereto included 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 (it being understood that such counsel need not express any belief with respect to the financial statements, schedules and other financial and accounting data or statistical data derived therefrom or information about internal control over financial reporting included or incorporated by reference in the Registration Statement, the Pre-Pricing Prospectus, the Prospectus or any Permitted Free Writing Prospectus).

(c) The Representative shall have received on the Closing Date or the Option Closing Date, as the case may be, the opinions of ▇▇▇ ▇. ▇▇▇▇▇, Esq., Executive Vice President - General Counsel for the Company, dated the Closing Date or the Option Closing Date, as the case may be, addressed to the Underwriters (and stating that it may be relied upon by counsel to the Underwriters) to the effect that:

(i) The Company has been duly incorporated and is presently subsisting as a corporation under the laws of the Commonwealth of Pennsylvania, with corporate power and authority to own or lease its properties and conduct its business as described in the Pre-Pricing Prospectus and the Prospectus; API has been duly incorporated and is presently subsisting as a corporation under the laws of the Commonwealth of Pennsylvania, with corporate power and authority to own or lease its properties and conduct its business as described in the Pre-Pricing Prospectus and the Prospectus; the Company and API are duly qualified to transact business in all jurisdictions in which the conduct of their business requires such qualification, except for such jurisdictions where the failure to so qualify would not have a Materially Adverse Effect; and the outstanding shares of capital stock of API have been duly authorized and validly issued and are fully paid and non-assessable and are owned by the Company; and, to such counsel’s knowledge, the outstanding shares of capital stock of API are owned free and clear of all liens, encumbrances and equities and claims, and no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligations into any shares of capital stock or of ownership interests in API are outstanding.

(ii) Except as described in or contemplated by the Pre-Pricing Prospectus and the Prospectus, there are no outstanding securities of the Company convertible or exchangeable into or evidencing the right to purchase or subscribe for any shares of capital stock of the Company and there are no outstanding or

authorized options, warrants or rights of any character obligating the Company to issue any shares of its capital stock or any securities convertible or exchangeable into or evidencing the right to purchase or subscribe for any shares of such stock; and except as described in the Pre-Pricing Prospectus and the Prospectus, no holder of any securities of the Company or any other person has the right, contractual or otherwise, which has not been satisfied or effectively waived, to cause the Company to sell or otherwise issue to them, or to permit them to underwrite the sale of, any of the Shares or the right to have any common shares or other securities of the Company included in the Registration Statement or the right, as a result of the filing of the Registration Statement, to require registration under the Act of any shares of Common Stock or other securities of the Company.

(iii) Each of the Company and the Subsidiaries owns, possesses, has obtained or meets the requirements for all licenses, permits, certificates, consents, orders, approvals and other authorizations from, and has made all declarations and filings with, all federal, state, local and other governmental authorities (including foreign regulatory agencies), all self-regulatory organizations and all courts and other tribunals, domestic or foreign, necessary to own or lease, as the case may be, and to operate its properties and to carry on its business as conducted as of the date hereof except where the lack thereof would not have a Material Adverse Effect, and neither the Company nor any such Subsidiary has received any actual written notice of any proceeding relating to revocation or modification of any such license, permit, certificate, consent, order, approval or other authorization that would materially interfere with its ownership or lease, as the case may be, or the operation of its properties or the carrying on of its business as conducted on the date hereof, except as described in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus or as would not have a Material Adverse Effect; and to his knowledge, each of the Company and the Subsidiaries is in material compliance with all laws and regulations relating to the conduct of its business as conducted as of the date of the Prospectus except where such noncompliance would not have a Material Adverse Effect.

(d) The Representative shall have received from ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇ (“▇▇▇▇▇ ▇▇▇▇”), counsel for the Underwriters, an opinion dated the Closing Date or such Option Closing Date, as the case may be, substantially to the effect specified in paragraph (b)(x) of this Section 6. In rendering such opinion ▇▇▇▇▇ ▇▇▇▇ may rely as to all matters governed

other than by the laws of the State of New York or Federal laws on the opinion of counsel referred to in Paragraph (b) of this Section. In addition to the matters set forth above, such opinion shall also include a statement to the effect that nothing has come to the attention of such counsel which leads them to believe that (i) the Registration Statement, or any amendment thereto, as of the date hereof 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 (except that such counsel need express no view as to financial statements, schedules and statistical information therein), (ii) the Prospectus, or any supplement thereto, on the date hereof and as of the Closing Date or the Option Closing Date, as the case may be, 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 that such counsel need express no view as to financial statements, schedules and statistical information therein) (iii) the Registration Statement, the Pre-Pricing Prospectus, if applicable, and the Prospectus appear on their face to be appropriately responsive in all material respects to the requirements of the Act and the applicable rules and regulations of the Commission thereunder, and (iv) the Pre-Pricing Prospectus, as of its date, the date hereof and at the time of purchase, in the later such case together with the pricing information set forth in Schedule A hereof, includes or included 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, in the light of the circumstances under which they were made, not misleading. With respect to such statement, ▇▇▇▇▇ ▇▇▇▇ may state that their belief is based upon the procedures set forth therein, but is without independent check and verification.

(e) The Representative shall have received, on the date hereof, on the Closing Date and, if applicable, the Option Closing Date, a letter of Pricewaterhouse Coopers LLP dated the date hereof, the Closing Date or the Option Closing Date, as the case may be, in form and substance satisfactory to you and PricewaterhouseCoopers LLP to the effect that: (i) they are an independent registered public accounting firm with respect to the Company within the meaning of the Act, the Rules and Regulations and the rules and regulations of the PCAOB, (ii) in their opinion, the consolidated financial statements of the Company and its subsidiaries audited by them and incorporated in the Registration Statement, the Prospectus and, if applicable, the Pre-Pricing Prospectus, comply as to form in all material respects with the applicable accounting requirements of the Act and the related published Rules and Regulations; and (iii) such other procedures as the Representative may request and Pricewaterhouse Coopers LLP are willing to perform and report on.

(v) Since the respective dates as of which information is given in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus, there has not been any change or any development that has had or will have a Material Adverse Effect.

The obligations of the Company pursuant to this Agreement are subject to the conditions that at the Closing Date or the Option Closing Date, as the case may be, no stop order suspending the effectiveness of the Registration Statement shall have been issued and in effect or proceedings therefor initiated or threatened.

8. INDEMNIFICATION.

(a) The Company agrees:

(i) to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (A) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or any Prospectus (the term Prospectus for the purpose of this Section 8 being deemed to include the Base Prospectus, the Pre-Pricing Prospectus, the Prospectus and any

amendments or supplements to the foregoing), in any “issuer free writing prospectus” as defined in Rule 433 under the Act, in the Disclosure Package (when considered together with the pricing information set forth in Schedule A hereto), or in any “issuer information” as defined in Rule 433 under the Act of the Company included, with the Company’s prior written consent (which consent shall not be unreasonably withheld), in a free writing prospectus of an offering participant other than the Company or (B) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission, made in any such document or documents, in reliance upon and in conformity with written information furnished to the Company by or through the Representative specifically for use in the preparation thereof; and

(ii) to reimburse each Underwriter and each such controlling person upon demand for any legal or other out-of-pocket expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriters were not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriters will promptly return all sums that had been advanced pursuant hereto.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the Registration Statement, and each person, if any, who controls the Company within the meaning of the Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer, or controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus or any amendment or supplement thereto, or (ii) the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make

the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, the Prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representative specifically for use in the preparation thereof. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 8, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 8(a) or 8(b) shall be available to any party who shall fail to give notice as provided in this Section 8(c) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a) or 8(b). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within

a reasonable period of time after notice of commencement of the action. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by the Representative in the case of parties indemnified pursuant to Section 8(a) and by the Company in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding and does not include an admission of fault or culpability or a fraudulent act by or on behalf of such indemnified party.

(d) To the extent the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) 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. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits 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 which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions

received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault 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 on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) 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 which does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter, and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 8(d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) In any proceeding relating to the Registration Statement, the Prospectus or any supplement or amendment thereto, each party against whom contribution may be sought under this Section 8 hereby consents to the jurisdiction of any court having jurisdiction over any other contributing party, agrees that process issuing from such court may be served upon it by any other contributing party and consents to the service of such process and agrees that any other contributing party may join it as an additional defendant in any such proceeding in which such other contributing party is a party.

(f) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company set forth

in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Company, its directors or officers or any persons controlling the Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter, or any person controlling any Underwriter, or to the Company, its directors or officers, or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8.

9. DEFAULT BY UNDERWRITERS.

If on the Closing Date or such Option Closing Date, as the case may be, any Underwriter shall fail to purchase and pay for the portion of the Shares which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Company), you, as Representative of the Underwriters, shall use your reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Company such amounts as may be agreed upon and upon the terms set forth herein, the Shares which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours you, as such Representative, shall not have procured such other Underwriters, or any others, to purchase the Shares agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of shares with respect to which such default shall occur does not exceed 10% of the Shares to be purchased on the Closing Date or the Option Closing Date, as the case may be, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Shares which they are obligated to purchase hereunder, to purchase the Shares which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of Shares with respect to which such default shall occur exceeds 10% of the Shares to be purchased on the Closing Date or the Option Closing Date, as the case may be, the Company or you as Representative will have the right, by written notice given within the next 36-hour period to the parties to this Agreement, to terminate this Agreement without liability on the part of any non-defaulting Underwriter or of the Company except to the extent provided in Sections 5 and 8 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section 9, the Closing Date or Option Closing Date, as the case may be, may be postponed for such period, not exceeding seven days, as the Company or you, as Representative, may determine in order that the required changes in the Registration Statement or in the Prospectus or in any other documents or arrangements may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section 9 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

governmental authority which in your reasonable opinion would create a Material Adverse Effect, (v) the declaration of a banking moratorium by United States or New York State authorities, (vi) any downgrading, or placement on any watch list for possible downgrading, in the rating of any of the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Exchange Act), (vii) the suspension of trading of the Company’s Common Stock by the New York Stock Exchange, the Commission, or any other governmental authority or (viii) the taking of any action by any governmental body or agency in respect of its monetary or fiscal affairs which in your reasonable opinion has a material adverse effect on the securities markets in the United States; or

(b) as provided in Sections 6 and 9 of this Agreement.

Any such termination shall be without liability of any party to any other party except that the provisions of Section 5 and 8 hereof shall at all times be effective.

12. SUCCESSORS.

This Agreement has been and is made solely for the benefit of the Underwriters and the Company and their respective successors, executors, administrators, heirs and assigns, and the officers, directors and controlling persons referred to herein, and no other person will have any right or obligation hereunder. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign merely because of such purchase.

13. INFORMATION PROVIDED BY UNDERWRITERS.

The Company and the Underwriters acknowledge and agree that the only information furnished or to be furnished by any Underwriter to the Company for inclusion in any Prospectus Supplement consists of following information set forth under the caption “Underwriting” in the Prospectus Supplement: the information in the second and third sentences under “Commissions and Discounts” and the information under “Price Stabilization and Short Positions”.

14. MISCELLANEOUS.

The reimbursement, indemnification and contribution agreements contained in this Agreement and the representations, warranties and covenants in this Agreement shall remain in full force and effect regardless of (a) any termination of this Agreement, (b) any investigation made by or on behalf of any Underwriter or controlling person thereof, or by or on behalf of the Company or its directors or officers and (c) delivery of and payment for the Shares under this Agreement.

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

15. SUBMISSION TO JURISDICTION.

Except as set forth below, no claim arising out of or in any way relating to this Agreement may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Company consents to the jurisdiction of such courts and personal service with respect thereto. The Company hereby consents to personal jurisdiction, service and venue in any court in which any claim arising out of or in any way relating to this Agreement is brought by any third party against any Underwriter or any indemnified party. Each Underwriter and the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its shareholders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Company agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Company and may be enforced in any other courts in the jurisdiction of which the Company is or may be subject, by suit upon such judgment.

16. NO FIDUCIARY RELATIONSHIP.

The Company hereby acknowledges that the Underwriters are acting solely as underwriters in connection with the purchase and sale of the Shares.

The Underwriters hereby expressly disclaim any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriters to

the Company regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Company’s securities, do not constitute advice or recommendations to the Company. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

FORM OF LOCK-UP AGREEMENT

The undersigned, being one of the executive officers or directors (together, the “Restricted Group”) of Aqua America, Inc. (the “Company”), understands that ▇.▇. ▇▇▇▇▇▇▇ & Sons, Inc., on behalf of the Underwriters listed on Schedule I to the Underwriting Agreement (as defined below) (the “Underwriters”), proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company providing for the public offering by the Underwriters of common stock (the “Common Stock”), of the Company (the “Public Offering”).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned agrees not to offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or hedge any additional shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, or publicly disclose the intention to make any such offer, sale, pledge, disposition, or hedge or request the registration for the offer or sale of any of the foregoing (or as to which such person has the right to direct the disposition of) (each of the foregoing referred to as a “Disposition”), directly or indirectly, except with the prior written consent of ▇.▇. ▇▇▇▇▇▇▇ & Sons, Inc. at its sole discretion, for a period from the date hereof until and including the date that is 90 days after the date of the final prospectus relating to the Public Offering (the “Lock-Up Period”), provided however, that such restriction shall not apply to (i) sales by members of the Restricted Group of up to a group aggregate amount of 40,000 shares of the Company’s common stock that occur more than 30 days after the date of the Underwriting Agreement, which sales are approved in writing by the Company, (ii) sales by the undersigned of Common Stock to the Company in connection with cash-less exercise of options, (iii) sales under existing stock trading plans specified in Rule 10b5-1 of the Securities Exchange Act of 1934, or (iv) entering into a stock trading plan in accordance with the guidelines specified in Rule 10b5-1 of the Securities Exchange Act of 1934, provided any sales of Common Stock under such plan are subject to the terms of this Lock-Up Agreement. The foregoing restriction is expressly intended to preclude the undersigned from engaging in any Hedging Transaction or other transaction which is designed to or reasonably expected to lead to or result in a Disposition during the Lock-Up Period even if the securities would be disposed of by someone other than the undersigned. “Hedging Transaction” means any short sale (whether or not against the box) or any purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from the Common Stock.

S-4

Notwithstanding the above, if (i) during the last 15 calendar days plus 3 business days of the 90-day lock-up period the Company issues an earnings release or material news or a material event relating to the Company occurs or (ii) prior to the expiration of the 90-day lock-up period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day lock up period, then the restrictions described above will continue to apply until the expiration of the 15 calendar days plus 3 business days beginning on the issuance of the earnings release or the occurrence of the material news or material event.

Notwithstanding the foregoing, the undersigned may transfer (a) shares of Common Stock acquired in open market transactions by the undersigned after the completion of the Public Offering, and (b) any or all of the shares of Common Stock or other Company securities if the transfer is by (i) gift, will or intestacy, or (ii) distribution to partners, members or shareholders of the undersigned; provided, however, that in the case of a transfer pursuant to clause (b) above, it shall be a condition to the transfer that the transferee execute an agreement with the Underwriters stating that the transferee is receiving and holding the securities subject to the provisions of this letter agreement.

The undersigned agrees that the Company may, and that the undersigned will, (i) with respect to any shares of Common Stock or other Company securities for which the undersigned is the record holder, cause the transfer agent for the Company to note stop transfer instructions with respect to such securities on the transfer books and records of the Company and (ii) with respect to any shares of Common Stock or other Company securities for which the undersigned is the beneficial holder but not the record holder, cause the record holder of such securities to cause the transfer agent for the Company to note stop transfer instructions with respect to such securities on the transfer books and records of the Company.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this letter agreement. All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned and any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

The undersigned understands that if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the shares to be sold thereunder, the undersigned shall be released from all obligations of this Lock-Up Agreement.
