Ladies and Gentlemen:

Barrier Therapeutics, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the Underwriters named in Schedule I annexed hereto (the “Underwriters”) an aggregate of 4,820,000 shares of Common Stock, $0.0001 par value per share (the “Common Stock”), of the Company (the “Firm Shares”). The Firm Shares are also referred to as the “Offered Securities.”

1. Representations and Warranties. The Company represents and warrants to, and agrees with, the Underwriters as set forth below in this Section.

(a) A registration statement on Form S-3 (No. 333-134214) relating to the Offered Securities, including a form of prospectus (the “initial registration statement”), has been filed with the Securities and Exchange Commission (the “Commission”) and was declared effective on May 25, 2006 (the “Initial Registration Statement Effective Date”). As used in this Underwriting Agreement, “Registration Statement” as of any time means such registration statement in the form then filed with the Commission, including any amendment thereto, any document incorporated by reference therein and any information in a prospectus or prospectus supplement deemed or retroactively deemed to be a part thereof pursuant to Rule 430B (“Rule 430B”) or 430C (“Rule 430C”) under the Securities Act of 1933 (“Act”) that has not been superseded or modified. “Registration Statement” without reference to a time means the Registration Statement as of the time of the first contract of sale for the Offered Securities, which time shall be considered the “Effective Date” of the Registration Statement relating to the Offered Securities. For purposes of this definition, information contained in a form of prospectus or prospectus supplement that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Registration Statement as of the time specified in Rule 430B. For purposes of this Underwriting Agreement, “Applicable Time” means 11:45 p.m. Pacific Daylight Time on September 14, 2006.

“Statutory Prospectus” as of any time means the prospectus relating to the Offered Securities that is included in the Registration Statement immediately prior to that time, including any document incorporated by reference therein and any basic prospectus or prospectus supplement deemed to be a part thereof pursuant to Rule 430B or 430C that has not been superseded or modified. For purposes of this definition, information contained in a form of prospectus (including a prospectus supplement) that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Statutory Prospectus only as of the actual time that form of prospectus (including a prospectus supplement) is filed with the Commission pursuant to Rule 424(b) (“Rule 424(b)”) under the Act. “Prospectus” means the Statutory Prospectus that discloses the public offering price and other final terms of the Offered Securities and otherwise satisfies Section 10(a) of the Act.

“Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 (“Rule 433”) under the Act, relating to the Offered Securitiesin the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g). “General Use Issuer Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its being specified in Schedule III. “Limited Use Issuer Free Writing Prospectus” means any Issuer Free Writing Prospectus that is not a General Use Issuer Free Writing Prospectus.

(b) On the Initial Registration Statement Effectiveness Date, at the time of each amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether by post-effective amendment, incorporated report or form of prospectus) and on the Effective Date, the Registration Statement complied and will comply in all material respects with the requirements of the Act and the rules and regulations of the Commission (the “Rules and Regulations”) and did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein in light of the circumstances under which they were made (with respect to the Prospectus and any supplement or amendment thereto) not misleading. At the Applicable Time, the Registration Statement and the Statutory Prospectus will comply in all material respects with the requirements of the Act and the Rules and Regulations, and neither of such documents contains, or will contain, any untrue statement of a material fact or omits, or will omit, to state any 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; provided, however, that the Company makes no representations or warranties as to the information contained in or omitted from the Registration Statement or the Prospectus in reliance upon and in conformity with information furnished herein or in writing to the Company by or on behalf of the Underwriters for inclusion therein, it being understood and agreed that the only such information is that described in Section 11 hereof.

(c) The date of this Underwriting Agreement is not more than three years subsequent to the more recent of the initial effective date of the Registration Statement or December 1, 2005. If, immediately prior to the third anniversary of the more recent of the initial effective date of the Registration Statement or December 1, 2005, any of the Offered Securities remain unsold by the Underwriters, the Company, prior to that third anniversary file, if it has not already done so, will file a new shelf registration statement relating to the Offered Securities, in a

form satisfactory to the Underwriters, will use its best efforts to cause such registration statement to be declared effective within 180 days after that third anniversary, and will take all other action necessary or appropriate to permit the public offering and sale of the Offered Securities to continue as contemplated in the expired registration statement relating to the Offered Securities. References herein to the Registration Statement shall include such new shelf registration statement.

(d) As of the Applicable Time, neither (i) the General Use Issuer Free Writing Prospectus(es) issued at or prior to the Applicable Time, the Statutory Prospectus at the Applicable Time and the information set forth in Schedule III, all considered together (collectively, the “General Disclosure Package”), nor (ii) any individual Limited Use Issuer Free Writing Prospectus, when considered together with the General Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from any prospectus included in the Registration Statement or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by the Underwriter specifically for use therein, it being understood and agreed that the information furnished by the Underwriters consists only of the information described in Section 11 hereto.

(e) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Offered Securities or until any earlier date that the Company notified or notifies the Underwriters as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information then contained in the Registration Statement. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, (i) the Company has promptly notified or will promptly notify the Underwriters and (ii) the Company has promptly amended or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by the Underwriters specifically for use therein, it being understood and agreed that the information furnished by the Underwriters consists only of the information described in Section 11 hereto. The Company has complied with and will comply with Rule 433.

corporation in good standing in New Jersey, which is the only jurisdiction in which the conduct of its business requires such qualification, except where the failure to be so qualified or be in good standing would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the financial condition, business, properties, or results of operations of the Company (“Material Adverse Effect”). The Company has not received a written notification that any proceeding has been instituted in any such jurisdiction, revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification, and to the Company’s knowledge, no proceeding has been instituted in any such jurisdiction, revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification. The Company is in possession of and operating in material compliance with all authorizations, licenses, certificates, consents, orders and permits from state, federal and other regulatory authorities that are material to the conduct of its business, all of which are valid and in full force and effect. Neither the Company nor either Subsidiary is in violation of its charter or bylaws. The Company does not own or control, directly or indirectly, any corporation, association or other entity other than the Subsidiaries.

(g) The Company has all requisite corporate power and authority to enter into this Underwriting Agreement and perform the transactions contemplated hereby. This Underwriting Agreement has been duly authorized, executed and delivered by the Company and is a valid and binding agreement on the part of the Company, enforceable in accordance with its terms, except as may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally or by general equitable principles. The performance of this Underwriting Agreement and the consummation of the transactions herein contemplated will not result in (A) any violation of the charter or bylaws of the Company or any Subsidiary or (B) a breach or violation of any of the terms and provisions of, or constitute a default under any contract, agreement, license, understanding, indenture, mortgage, deed of trust, loan agreement, joint venture, lease (including without limitation any sale and leaseback arrangement) or bond, debenture, note or other evidence of indebtedness, to which the Company or any Subsidiary is a party or by or to which it or its properties (including without limitation all Company Intellectual Property (as defined in Section 1(v)) are or may be bound or subject (each, a “Contract”) or any law, order, ruling, rule, regulation, writ, assessment, injunction, judgment or decree of any government or governmental court, agency or body, domestic or foreign, having jurisdiction over the Company, any Subsidiary or over any of their respective properties (including without limitation all Company Intellectual Property) or Contracts (“Government Entity”) or by or to which they or such of their properties or Contracts are or may be bound or subject (each, a “Law”), except in the case of this clause (B), such defaults or violations which would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. No consent, approval, authorization or order of or qualification with any Government Entity is required for the execution and delivery of this Underwriting Agreement and the consummation by the Company of the transactions herein contemplated, except such consents (i) that will be obtained prior to the Closing Date (as defined in Section 2) and (ii) as may be required under the Act, the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (if applicable), the Rules and Regulations, or under state or other securities or blue sky laws, the NASDAQ Global Market or the National Association of Securities Dealers, Inc. (the “NASD”), all of which requirements will be satisfied in all material respects at or prior to the Closing Date.

(h) Except as disclosed in the General Disclosure Package, there are no actions, suits, claims, investigations or proceedings pending or, to the Company’s knowledge, threatened to which the Company or any Subsidiary or, to the Company’s knowledge, to which any of their respective directors or officers is a party, or of which any of their respective properties (including without limitation all Company Intellectual Property) or any Contract is the subject, at law or in equity, before or by any federal, state, local or foreign governmental or regulatory commission, board, body, authority or agency which, if adversely decided, would be reasonably likely to result in a decision, ruling, finding, judgment, decree, order or settlement having a Material Adverse Effect or to prevent consummation of the transactions contemplated hereby. There are no Contracts of a character required to be described or referred to in General Disclosure Package, and/or filed as an exhibit to, the Registration Statement or the Prospectus by the Act, the Exchange Act or the Rules and Regulations which have not been accurately described in all material respects in the General Disclosure Package, and/or filed as an exhibit to, the Registration Statement or the Statutory Prospectus at the Applicable Time, as applicable. The Contracts described in the General Disclosure Package are in full force and effect and are valid agreements, enforceable by the Company, except as the enforcement thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally or by general equitable principles. No event has occurred, and no circumstance or condition exists, that (with or without notice or lapse of time) (A) has resulted or is reasonably likely to result in a breach, default, violation or waiver of any Contract or any provision thereof; (B) gives or is reasonably likely to give any party to any Contract the right to declare a breach, default or violation of or exercise any remedy under such Contract; (C) gives or is reasonably likely to give any party to any Contract the right to cancel, terminate, modify or be excused from performance of any obligations under such Contract; or (D) has resulted or is reasonably likely to result in a violation of any Law or in imposition of any fines, penalties, damages, injunctions, prohibitions or other sanctions, except in the cases of clauses (A), (B) and (C), where such breaches, defaults, violations, waivers, remedies, cancellations, terminations, modifications, excuses or impositions might not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(i) All outstanding shares of capital stock of the Company and each Subsidiary have been duly authorized and validly issued and are fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and have not been issued in violation of or subject to any preemptive rights or other rights to subscribe for or purchase securities. The Company owns all of the outstanding shares of the Subsidiaries. The authorized and outstanding capital stock of the Company as set forth in the Statutory Prospectus at the Applicable Time conforms in all material respects to the statements relating thereto contained in the General Disclosure Package (and such statements correctly state the substance of the instruments defining the capitalization of the Company). The Offered Securities have been duly authorized for issuance and sale to the Underwriters pursuant to this Underwriting Agreement and, when issued and delivered by the Company against payment therefor in accordance with the terms of this Underwriting Agreement, will be duly and validly issued and fully paid and nonassessable, and will be sold free and clear of any pledge, lien, security interest, encumbrance, claim or equitable interest. No preemptive right, co-sale right, registration right, right of first refusal or other similar right of stockholders exists with respect to any of the Offered Securities or the issuance and sale thereof, other than those that have been expressly waived prior to the date hereof, those that will have been expressly waived prior to the Closing Date (as defined in

Section 2 below), and those that will automatically expire upon or will not apply to the consummation of the transactions contemplated on the Closing Date. No further approval or authorization of any stockholder, the Board of Directors of the Company or others is required for the issuance and sale or transfer of the Offered Securities, except as may be required under state or other securities or blue sky laws, or the NASD. Except as disclosed in the General Disclosure Package and the financial statements of the Company, and the related notes thereto, included or incorporated by reference in the Statutory Prospectus at the Applicable Time, the Company does not have outstanding any options to purchase, any securities or obligations convertible into, or any contracts or commitments to issue or sell, shares of its capital stock or any such options, rights, registration rights, convertible securities or obligations. The description of the Company’s stock option plans, employee stock purchase plans or similar arrangements, and the options or other rights granted and exercised thereunder, set forth in the General Disclosure Package accurately and fairly presents, in all material respects, the information required to be shown with respect to such plans, arrangements, options and rights.

Except as set forth in the General Disclosure Package, the Company owns or leases all such properties as are necessary to its operations as now conducted or as proposed to be conducted. A “Permitted Lien” shall mean (i) liens for taxes not yet due, (ii) mechanics liens and similar liens for labor, materials or supplies incurred in the ordinary course of business for amounts that are not delinquent and (iii) any liens that individually or in the aggregate are not material.

(o) The Company and each Subsidiary have timely filed all federal, state and foreign income and franchise tax returns required to be filed by the Company and the Subsidiaries on or prior to the date hereof, and has paid all taxes shown thereon as due, and there is no tax deficiency that has been or, to the Company’s knowledge, might be asserted against the Company or any Subsidiary that would reasonably be expected to have a Material Adverse Effect. All material tax liabilities are adequately provided for on the books of the Company.

(p) The Company has established and maintains a system of internal accounting controls sufficient to provide reasonable assurances that: (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles in the United States and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

The Audit Committee has reviewed the adequacy of its charter within the past 12 months.

(r) The Company has established and maintains disclosure controls and procedures (as such term is defined in Rules 13a-15 and 15d-15 under the Exchange Act). Since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses. The Company is in compliance in all material respects with all provisions currently in effect and applicable to the Company of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002, and all rules and regulations promulgated thereunder or implementing the provisions thereof.

(s) The Company maintains insurance with insurers of recognized financial responsibility of the types and in the amounts it reasonably believes to be adequate for its business and consistent with insurance coverage maintained by similar companies in similar businesses, including, but not limited to, insurance covering the acts and omissions of directors and officers, real and personal property owned or leased by the Company against theft, damage, destruction, acts of vandalism and all other risks customarily insured against, all of which insurance is in full force and effect; and the Company has no reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that might not reasonably be expected to have a Material Adverse Effect.

(t) Neither the Company nor any Subsidiary has sustained since the date of the latest financial statements included in the General Disclosure Package any losses or interferences with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the General Disclosure Package or other than any losses or interferences which might not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(u) No labor dispute with employees of the Company exists or, to the Company’s knowledge, is imminent which would reasonably be expected to have a Material Adverse Effect. No collective bargaining agreement exists with any of the Company’s employees and, to the Company’s knowledge, no such agreement is imminent.

“Company Intellectual Property”), except for any Company Intellectual Property the absence of which, individually or in the aggregate, would not have a Material Adverse Effect. The Company Intellectual Property is free and clear of any pledge, lien, security interest, encumbrance, claim or equitable interest, whether imposed by agreement, contract, understanding, law, equity or otherwise, except for Permitted Liens or where any failure to have such adequate licenses or other rights of use to such Intellectual Property, individually or in the aggregate, would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. Neither the Company nor any Subsidiary is obligated to pay a royalty, grant a license or provide other consideration to any third party in connection with the Company Intellectual Property other than as disclosed in the General Disclosure Package. Except as disclosed in the General Disclosure Package or as would not have a Material Adverse Effect, (i) neither the Company nor any Subsidiary has received any notice of infringement or conflict with asserted rights of others with respect to any Company Intellectual Property, (ii) the conduct of the business of the Company in the manner described in the General Disclosure Package does not and will not, to the knowledge of the Company, infringe, interfere or conflict with any valid issued patent claim or other Intellectual Property right of any third party and (iii) no third party, including any academic or governmental organization, possesses or could obtain rights to the Company Intellectual Property which, if exercised, could enable such party to develop products competitive to those of the Company and the Subsidiaries. Except as disclosed in the General Disclosure Package, neither the Company nor any Subsidiary has received any notice or has any knowledge of (i) any potential infringement or misappropriation by others of the Company Intellectual Property or (ii) any Intellectual Property of others that potentially conflicts or interferes with the Company Intellectual Property, that might reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. To the Company’s knowledge, no claim of any patent or patent application (assuming the claims of patent applications issue as currently pending) included in the Company Intellectual Property is unenforceable or invalid, except for such unenforceability or invalidity that would not reasonably be expected to result, individually or in the aggregate, in a Material Adverse Effect. Each former and current employee and independent contractor of the Company has signed and delivered one or more written contracts with the Company pursuant to which such employee or independent contractor assigns to the Company all of his, her or its rights in and to any inventions, discoveries, improvements, works of authorship, know-how or information made, conceived, reduced to practice, authored or discovered in the course of employment by or performance of services for the Company and any and all patent rights, copyrights, trademark and other intellectual property rights therein or thereto.

Except as described in the General Disclosure Package, the Company has not received any notification that the Commission or the NASDAQ Stock Market LLC is contemplating terminating such registration or listing. The Company has taken all actions necessary to list the Offered Securities for quotation on the NASDAQ Global Market.

The Company acknowledges that the Underwriters may engage in passive market making transactions in the Offered Securities on the NASDAQ Stock Market LLC in accordance with Regulation M under the Exchange Act.

(aa) The Company is in compliance in all material respects with all currently applicable provisions of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”), except where a failure to so comply might not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect; to the Company’s knowledge, no unwaivable “reportable event” (as defined in ERISA) has occurred with respect to any “pension plan” (as defined in ERISA) for which the Company would have any liability; the Company has not incurred and does not expect to incur any material liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (ii) Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each “pension plan” for which the Company would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification.

Section 9601, et seq.), or otherwise designated as a contaminated site under applicable state or local law.

(cc) There are no outstanding loans, advances (except normal advances for business expenses in the ordinary course of business) or guarantees of indebtedness by the Company to or for the benefit of any of the officers or directors of the Company or any of the members of the families of any of them, except as disclosed in the General Disclosure Package.

(dd) To the Company’s knowledge, there are no affiliations or associations between any member of the NASD and any of the Company’s officers or directors or, to the Company’s knowledge, any of the Company’s 5% or greater security holders, except as set forth in the General Disclosure Package.

(b) Each Underwriter severally agrees to indemnify, defend and hold harmless the Company, its directors and officers, and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and the successors and assigns of all of the foregoing persons from and against any loss, damage, expense, liability or claim (including but not limited to reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation) which the Company or any such person may incur under the Act, the

Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information furnished by or on behalf of such Underwriter to the Company expressly for use with reference to such Underwriter in the Registration Statement, any Statutory Prospectus, the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement thereto, or any related preliminary prospectus, or (ii) any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement, such Statutory Prospectus at the Applicable Time or such Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, or necessary to make such information not misleading.

(c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action in respect of which indemnity could be sought under this Section 9, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party in writing of the commencement thereof, but the failure to notify the indemnifying party will not relieve the indemnifying party from any liability which it may have to any indemnified party, except to the extent (but only to the extent) such indemnifying party is prejudiced thereby. In case any such action is brought against any indemnified party and the indemnified party notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party for separate counsel retained by the indemnified party in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding the foregoing, the indemnified party shall have the right to employ one separate counsel (in addition to any local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel, if (i) the use of the counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or the other indemnified parties which are inconsistent with those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action, or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. Any such separate counsel for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by Pacific Growth Equities, LLC, and any such separate counsel 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. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release

of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) If for any reason the indemnification provided for in this Section 9 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same respective proportions 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 such Underwriter, in each case as reflected 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 or the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take into account the equitable considerations referred to above. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have; and the obligations of the Underwriters under this Section shall be in addition to any liability which the Underwriters may otherwise have.

(f) The indemnity and contribution agreements, including, without limitation, with respect to the payment of expenses, contained in this Section 9 and the covenants, warranties and representations of the Company contained in this Underwriting Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Underwriters, their partners, directors or officers or any person (including each partner, officer or director of such

person) who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of the Company, its directors or officers or any person who controls any of the foregoing within the meaning of Section 15 of the Act, Section 20 of the Exchange Act, and shall survive the termination of this Underwriting Agreement or the issuance and delivery of the Offered Securities. The Company and the Underwriters agree promptly to notify each other of the commencing of any action in respect of indemnity against it and against any of the officers or directors of the Company in connection with the issuance and sale of the Offered Securities, or in connection with the General Disclosure Package.

10. Notices. All notices or communications hereunder, except as herein otherwise specifically provided, shall be in writing and if sent to the Underwriters shall be mailed, hand-delivered, sent via electronic mail (and confirmed by letter) or facsimile (and confirmed by letter) to the Underwriters c/o Pacific Growth Equities, LLC, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇, facsimile number (▇▇▇) ▇▇▇-▇▇▇▇, Attention: ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, Director of Compliance, with a copy to ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, Esq., Three ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, facsimile number (▇▇▇) ▇▇▇-▇▇▇▇; if sent to the Company, such notice shall be mailed, hand-delivered, sent via electronic mail (and confirmed by letter) or facsimile (and confirmed by letter) to ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, facsimile number, (▇▇▇) ▇▇▇-▇▇▇▇, electronic mail address, ▇▇▇▇▇▇▇▇@▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇, Attention: ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, General Counsel and Secretary, with a copy to ▇▇▇▇▇▇ ▇▇▇▇▇▇, Esq., ▇▇▇▇▇▇, ▇▇▇▇▇ & Bockius LLP, ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, facsimile number (▇▇▇) ▇▇▇-▇▇▇▇.

The Company waives to the fullest extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Offered Securities.

13. Parties at Interest. This Underwriting Agreement has been and is made solely for the benefit of the Underwriters, the Company and, to the extent provided in Section 9 hereof, the controlling persons, directors and officers referred to in such Section, and their respective successors, assigns, heirs, personal representatives and executors and administrators. No other person, partnership, association or corporation (including a purchaser, as such purchaser, from the Underwriters) shall acquire or have any right under or by virtue of this Underwriting Agreement.

14. Applicable Law. This Underwriting Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to principles of conflicts of laws.

15. Successors and Assigns. This Underwriting Agreement shall be binding upon the Underwriters and the Company and their successors and assigns and any successor assign of any substantial portion of the Company’s or any of the Underwriters’ business and/or assets.

16. Entire Agreement. This Underwriting Agreement constitutes the entire agreement of the parties hereto and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof.

13.		We have read the statements in or incorporated into the Statutory Prospectus at the Applicable Time and the Prospectus under the captions [list appropriate captions, including those related to regulatory matters] and Items 14 and 15 of Part II of the Registration Statement, and insofar as such statements constitute summaries of legal matters, contracts, agreements, documents or proceedings referred to therein, or refer to statements of law or legal conclusions, such statements are accurate in all material respects and fairly present the information purported to be shown.
