On August 16, 2018, Krystal Biotech, Inc. (the “Company”) entered into a stock purchase agreement (the “Purchase Agreement”) with the purchaser named therein for the private placement (the “Private Placement”) of 625,000 shares (the “Shares”) of the Company’s common stock, par value $0.00001 per share (the “Common Stock”) at $16 per share. The private placement yielded gross proceeds of $10 million and closed on August 17, 2018.

Pursuant to the Purchase Agreement, the Company also agreed to file a registration statement with the Securities and Exchange Commission (the “SEC”) registering the resale of the Shares, to have such registration statement declared effective within the time period set forth in the Purchase Agreement, and to keep such registration statement effective for up to three years. The Company will pay all expenses of the registration, excluding fees of legal counsel for the purchaser of the Shares.

The Purchase Agreement contains customary representations, warranties and agreements by the Company, indemnification obligations of the Company and the Purchasers, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), and other obligations of the parties. The representations, warranties and covenants contained in the Purchase Agreement were made only for purposes of such Purchase Agreement and are made as of specific dates; are solely for the benefit of the parties (except as specifically set forth therein); may be subject to qualifications and limitations agreed upon by the parties in connection with negotiating the terms of the Purchase Agreement, instead of establishing matters as facts; and may be subject to standards of materiality and knowledge applicable to the contracting parties that differ from those applicable to the investors generally. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of the Company.

The securities to be issued by the Company pursuant to the Purchase Agreement have not been registered under the Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. The Company relied and will rely on the private placement exemption from registration provided by Section 4(a)(2) of the Securities Act.

The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the Form of Securities Purchase Agreement filed as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.

5.1    Risk Such Purchaser, taking into account the personnel and resources it can practically bring to bear on the purchase of the Shares contemplated hereby, is knowledgeable, sophisticated and experienced in making, and is qualified to make, decisions with respect to investments in securities presenting an investment decision like that involved in the purchase of the Shares, including investments in securities issued by the Company, and has requested, received, reviewed and considered all information the Purchasers know about and deem relevant (including the SEC Documents) in making an informed decision to purchase the Shares.

5.2    Purchase for Investment. Purchaser is acquiring the Shares pursuant to this Agreement for its own account for investment only and with no present intention of distributing any of such Shares or any arrangement or understanding with any other Persons regarding the distribution of such Shares, except in compliance with Section 5.4.

5.3    Reliance. Such Purchaser understands that the Shares are being offered and sold to it in reliance upon specific exemptions from the registration requirements of the Securities Act, the Rules and Regulations and state securities laws and that the Company is relying upon the truth and accuracy of, and such Purchaser’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire the Shares. If any of the representations deemed to have been made by it by its purchase of the Shares are no longer accurate prior to Closing, the Investor shall promptly notify the Company. If such Purchaser is acquiring the Shares as a fiduciary or agent for one or more investor accounts, it represents that it has sole investment discretion with respect to each such account and it has full power to make the foregoing representations, acknowledgements and agreements on behalf of such account.

5.4    Compliance with the Securities Act. Such Purchaser will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any of the securities purchased hereunder except in compliance with the Securities Act, applicable blue sky laws, and the rules and regulations promulgated thereunder.

5.5    Accredited Investor. Such Purchaser is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under the Securities Act or a Qualified Institutional Buyer within the meaning of Rule 144A promulgated under the Securities Act.

10

5.6    Power and Authority. Such Purchaser has all requisite corporate power, and has taken all requisite corporate action, to authorize, execute and deliver this Agreement and each of the other agreements and instruments contemplated herein to which the Purchaser is a party, to consummate the transactions contemplated herein and therein and to carry out and perform all of such Purchaser’s obligations hereunder and thereunder. Upon the execution and delivery of this Agreement, this Agreement shall constitute a valid and binding obligation of such Purchaser, enforceable in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting the enforcement of creditors’ rights generally and (ii) as limited by equitable principles generally, including any specific performance.

5.7    Broker Dealer. Such Purchaser is not a broker or dealer registered pursuant to Section 15 of the Exchange Act (a “Registered Broker Dealer”) and is not an affiliate of a Registered Broker Dealer.

5.8    Sophisticated Investor. Such Purchaser acknowledges that it is a sophisticated investor engaged in the business of assessing and assuming investment risks with respect to securities, including securities such as the Shares, and further acknowledges that the Company is entering into this Agreement in reliance on this acknowledgment and such Purchaser’s understanding, acknowledgment and agreement that the Company has not disclosed to such Purchaser any material information concerning the Company’s currently ongoing Phase 1/2 clinical trial that has not been disclosed to the public in the Securities Filings, including information concerning the status of dosing of trial participants, or the reactivity of the Company’s KB103 product candidate in trial participants, including the expression, if any, of the COL7 gene, development of fibrils or other clinical observations or results (the “Trial Information”). Such Purchaser understands that the Trial Information may be material to a reasonable investor, such as Purchaser, when making investment decisions, including the decision to enter into this Agreement, and such Purchaser’s decision to enter into the Agreement is being made with full recognition and acknowledgment that the Company is privy to the Trial Information, irrespective of whether such Trial Information has been provided to Purchaser. Such Purchaser hereby waives any claim, or potential claim, it has or may have against the Company relating to the Company’s possession and non-disclosure of the Trial Information.

5.9    Other Securities Transactions. Such Purchaser has not, either directly or indirectly through an affiliate, agent or representative of the Company, engaged in any transaction in the securities of the Company other than with respect to the transactions contemplated herein, since the time that the Purchaser was first contacted by the Company or any other Person regarding the transactions contemplated hereby until the date hereof, except as set forth in filings made with the Commission pursuant to the Exchange Act.

5.10    Independent Advice. Such Purchaser understands that nothing in this Agreement or any other materials presented to such Purchaser in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. Such Purchaser has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Shares.

5.11    Legends. Such Purchaser understands that, until such time as the Shares may be sold pursuant to Rule 144, any certificates representing the Shares, whether maintained in a book entry system or otherwise, will bear one or more legends in substantially the following form and substance:

“THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY OTHER APPLICABLE SECURITIES LAWS

11

AND HAVE BEEN ISSUED IN RELIANCE UPON AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, HYPOTHECATED OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO A TRANSACTION WHICH IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION, IN EACH CASE IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS, AND, IN THE CASE OF A TRANSACTION EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION, THE HOLDER WILL NOTIFY ANY SUBSEQUENT PURCHASER OF THE SECURITIES EVIDENCED BY THIS CERTIFICATE FROM IT OF SUCH RESALE RESTRICTIONS.”

In addition any stock certificates, whether maintained in a book entry system or otherwise, representing the Shares may contain any legend required by the blue sky laws of any state to the extent such laws are applicable to the sale of such Shares hereunder. The Company shall use its commercially reasonable efforts to help facilitate the removal of such legend when it is legally permitted to do so under Rule 144, or to facilitate any transfer of the Shares under Rule 144 that may be requested by Purchasers, but shall not be obligated to incur any material costs or expenses in making such efforts.

5.12    Restricted Securities. Such Purchaser understands that the Shares are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such Shares may be resold without registration under the Securities Act only in certain limited circumstances. Accordingly, such Purchaser represents that it is familiar with Rule 144 of the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

SECTION 6.    REGISTRATION OF THE SHARES AND COMPLIANCE WITH THE SECURITIES ACT.

6.1    Registration Procedures and Expenses.

(a)    Piggyback Rights. In the event that the Company, in its sole discretion, shall determine to prepare and file a registration statement on Form S-3, or any other appropriate form on which the Shares may be registered for resale (each of the Shares, together with any shares of capital stock issued or issuable, from time to time, upon any reclassification, share combination, share subdivision, stock split, share dividend or similar transaction or event or otherwise as a distribution on, in exchange for or with respect to any of the foregoing, in each case held at the relevant time by a Purchaser, the “Registrable Securities”) by the Purchasers, whether or not on a continuous basis pursuant to Rule 415 under the Securities Act, which such registration statement may include shares that may be offered by the Company (the “Subsequent Registration Statement”), and has not previously filed a Secondary Registration Statement (as defined below), the Company shall: (i) notify each Purchaser of such determination; and (ii) if, within ten (10) days after receipt of such notice, any Purchaser requests in writing to include all or any part of its Registrable Securities in such Subsequent Registration Statement, include the Registrable Securities as so requested by the applicable Purchaser. Notwithstanding the foregoing and for avoidance of doubt, the Company may, but shall not be required to, file a Subsequent Registration Statement pursuant to this Agreement.

12

(b)    Secondary Registration Statement. If the Company has not previously filed a Subsequent Registration Statement, the Company shall, on or before October 8, 2018 (the “Filing Deadline”), use its best efforts to prepare and file with the Commission a Registration Statement on Form S-1 or S-3, as appropriate (the “Secondary Registration Statement”; where used hereafter, “Registration Statement” shall mean either a Subsequent Registration Statement which includes the Registrable Securities, or the Secondary Registration Statement, as applicable), relating to the resale of the Shares by the Purchasers on a continuous basis pursuant to Rule 415 under the Securities Act.

(c)    The Company shall use its best efforts, subject to receipt of necessary information from the Purchasers, to cause the Commission to declare a Registration Statement covering the Shares effective as soon as practicable after the date of the filing thereof and in any event no later than ninety (90) days after such filing if the Registration Statement has been filed on form S-3, and no later than one hundred twenty (120) days after such filing if such Registration Statement has been filed on Form S-1 (in either case, such date, the “Effectiveness Deadline”).

(d)    The Company shall promptly prepare and file with the Commission such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Registration Statement effective until the earliest of (i) the third anniversary of the effective date of the Registration Statement, (ii) such time as all of the Shares purchased by the Purchasers pursuant to the terms of this Agreement have been sold pursuant to the Registration Statement, or (iii) such time as the Shares become eligible for resale by non-affiliates without any volume limitations or other restrictions pursuant to Rule 144(b)(1)(i) under the Securities Act or any other rule of similar effect.

(e)    Notwithstanding the foregoing obligations, the Company may, upon written notice to the Purchasers, for a reasonable period of time, not to exceed 45 days in the case of clauses (A) and (B) below, or 30 days in the case of clause (C) below (each, a “Blackout Period”), delay the filing of a Secondary Registration Statement or a request for acceleration of the effective date, or suspend the effectiveness of any Registration Statement, in the event that (A) the Company is engaged in any activity or transaction or preparations or negotiations for any activity or transaction that the Company desires to keep confidential for business reasons, if the Company determines in good faith that the public disclosure requirements imposed on the Company under the Securities Act in connection with the Registration Statement would require at that time disclosure of such activity, transaction, preparations or negotiations and such disclosure could result in material harm to the Company or its business transactions or activities, (B) the Company does not yet have appropriate financial statements of any acquired or to be acquired entities necessary for filing, or (C) any other event occurs that makes any statement of a material fact made in such Registration Statement, including any document incorporated by reference therein, untrue or that requires the making of any additions or changes in the Registration Statement in order to make the statements therein not misleading; provided, however, that in the case of a Blackout Period pursuant to clause (A) above, the Blackout Period shall terminate upon the earlier of such 45-day period or the completion, resolution or public announcement of the relevant transaction or event. If the Company suspends the effectiveness of a Registration Statement pursuant to this Section 6.1(e), the Company shall, as promptly as reasonably practicable following the termination of the circumstance which entitled the Company to do so, take such actions as may be necessary to reinstate the effectiveness of such Registration Statement and give written notice to the Purchasers authorizing the Purchasers to resume offerings and sales pursuant to such Registration Statement. If as a result thereof the prospectus included in such Registration Statement has been amended or supplemented to comply with the requirements of the Securities Act, the Company shall enclose such revised prospectus with the notice to Investor given pursuant to this Section 6. The Company shall be entitled to exercise its rights under this Section 6.1(e) not more than once in any six (6) month period; provided, however, that the aggregate number of days of all Blackout Periods hereunder shall not exceed seventy-five (75) days in any twelve (12) month period.

13

After the expiration of any Blackout Period and without further request from the Investor, the Company shall effect the filing (or if required amendment or supplement) of the Registration Statement, or the filing of other documents, as necessary to allow the Investor to resell the Registrable Securities as set forth herein.

(f)    The Company shall furnish to the Purchasers with respect to the Shares registered under any Registration Statement (and to each underwriter, if any, of such Shares) such number of copies of prospectuses and such other documents as the Purchaser may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Shares by the Purchaser.

(g)    The Company shall bear all expenses in connection with the procedures in paragraphs (a) through (f) of this Section 6.1 and the registration of the Shares pursuant to the Registration Statement, other than fees and expenses, if any, of counsel or other advisers to the Purchasers or underwriting discounts, brokerage fees and commissions incurred by the Purchaser, if any in connection with the offering of the Shares pursuant to the Registration Statement.

(h)    In order to enable the Purchasers to sell the Shares under Rule 144 to the Securities Act, the Company shall use its commercially reasonable efforts to comply with the requirements of Rule 144, including without limitation, use its commercially reasonable efforts to comply with the requirements of Rule 144(c)(1) with respect to public information about the Company and to timely file all reports required to be filed by the Company under the Exchange Act.

(i)    The Company shall provide the Purchasers an opportunity to review and comment on all disclosures regarding the Purchasers and any plan of distribution proposed by them in connection with the preparation of any Registration Statement.

6.2    Restrictions on Transfer. Each Purchaser agrees that it will not effect any disposition of the Shares that would constitute a sale within the meaning of the Securities Act or pursuant to any applicable state securities laws, unless and until (1) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement or (2) such disposition is otherwise permitted by law. Notwithstanding the preceding sentence, no restriction shall apply to a transfer by a Purchaser that is a partnership transferring to its partners or former partners in accordance with partnership interests.

6.3    Indemnification. For the purpose of this Section 6.3: (i) the term “Purchaser/Affiliate” shall mean any affiliate of the Purchaser, including, without limitation, any general partner or managing member of the Purchaser, any investment adviser of the Purchaser, or any transferee who is an affiliate of the Purchaser, and any person who controls the Purchaser or any affiliate of the Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; and (ii) the term “Registration Statement” shall include any preliminary prospectus, final prospectus (the “Prospectus”), free writing prospectus, exhibit, supplement or amendment included in or relating to, and any document incorporated by reference in, the Registration Statement referred to in Section 6.1.

(a)    The Company agrees to indemnify and hold harmless the Purchasers and each Purchaser/Affiliate, against any losses, claims, damages, liabilities or expenses, joint or several, that such Purchaser or Purchaser/Affiliate incurs, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) (i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, including the Prospectus, financial statements and schedules, and all other

14

documents filed as a part thereof, as amended at the time of effectiveness of the Registration Statement, including any information deemed to be a part thereof as of the time of effectiveness pursuant to paragraph (b) of Rule 430A, or pursuant to Rules 430B, 430C or 434, of the Rules and Regulations, or the Prospectus, in the form first filed with the Commission pursuant to Rule 424(b) of the Regulations, or filed as part of the Registration Statement at the time of effectiveness if no Rule 424(b) filing is required or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state in any of them a material fact required to be stated therein or necessary to make the statements in the Registration Statement or any amendment or supplement thereto not misleading or in the Prospectus or any amendment or supplement thereto not misleading in light of the circumstances under which they were made or (ii) arise out of or are based in whole or in part on any inaccuracy in the representations or warranties of the Company contained in this Agreement, breach of any covenant of the Company contained in this Agreement or any failure of the Company to perform its other obligations hereunder or under law, and will promptly reimburse each Purchaser and each Purchaser/Affiliate for any legal and other out-of-pocket expenses as such expenses are reasonably incurred and documented by such Purchaser or such Purchaser/Affiliate in connection with investigating, defending or preparing to defend, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company will not be liable for amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the written consent of the Company, which consent shall not be unreasonably withheld or delayed, and the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon (i) the gross negligence or willful misconduct of such Purchaser, or (ii) an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Prospectus or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Purchaser expressly for use therein, or (iii) the inaccuracy of any representation or warranty made by such Purchaser herein or (iv) any statement or omission in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Purchaser prior to the pertinent sale or sales by the Purchaser. Any such indemnified Purchaser shall return all payments made hereunder if it is determined, by a final, non-appealable judgment by a court or arbitral tribunal, that the losses for which such payments were made resulted from such Indemnified Person’s gross negligence or willful misconduct.

(b)    Each Purchaser will severally, but not jointly, indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages, liabilities or expenses that the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person incurs, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, but only if such settlement is effected with the written consent of such Purchaser) insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon (i) any failure to comply with the covenants and agreements contained in Section 6.2 hereof respecting the sale of the Shares or (ii) the inaccuracy of any representation or warranty made by such Purchaser herein or (iii) any untrue or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements in the Registration Statement or any amendment or supplement thereto not misleading or in the Prospectus or any amendment or supplement thereto not misleading in the light of the circumstances under which they were made, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Purchaser

15

expressly for use therein; and will reimburse the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person for any legal and other expense reasonably incurred by the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that (i) each Purchaser’s aggregate liability under this Section 6 shall not exceed the amount of proceeds received by such Purchaser on the sale of the Shares pursuant to the Registration Statement and (ii) the Purchasers will not be liable for amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the written consent of the Purchasers, which consent shall not be unreasonably withheld or delayed.

(c)    Promptly after receipt by an indemnified party under this Section 6.3 of notice of the threat or commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 6.3 promptly notify the indemnifying party in writing thereof, but the omission to notify the indemnifying party will not relieve it from any liability that it may have to any indemnified party for contribution or otherwise under the indemnity agreement contained in this Section 6.3 to the extent it is not prejudiced as a result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party, and the indemnifying party and the indemnified party shall have reasonably concluded, based on an opinion of counsel reasonably satisfactory to the indemnifying party, that there may be a conflict of interest between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 6.3 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel, reasonably satisfactory to such indemnifying party, representing all of the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. In no event shall any indemnifying party be liable in respect of any amounts paid in settlement of any action unless the indemnifying party shall have approved in writing the terms of such settlement; provided that such consent shall not be unreasonably withheld. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnification could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d)    If the indemnification provided for in this Section 6.3 is required by its terms but is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party under paragraphs (a), (b) or (c) of this Section 6.3 in respect to any losses, claims, damages, liabilities or

16

expenses referred to herein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of any losses, claims, damages, liabilities or expenses referred to herein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Purchaser from the private placement of Shares hereunder 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 the relative fault of the Company and the Purchaser in connection with the statements or omissions or inaccuracies in the representations and warranties in this Agreement and/or the Registration Statement that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and each Purchaser on the other shall be deemed to be in the same proportion as the amount paid by such Purchaser to the Company pursuant to this Agreement for the Shares purchased by such Purchaser that were sold pursuant to the Registration Statement bears to the difference (the “Difference”) between the amount such Purchaser paid for the Shares that were sold pursuant to the Registration Statement and the amount received by such Purchaser from such sale. The relative fault of the Company on the one hand and each Purchaser on the other shall be determined by reference to, among other things, whether the untrue or alleged statement of a material fact or the omission or alleged omission to state a material fact or the inaccurate or the alleged inaccurate representation and/or warranty relates to information supplied by the Company or by such Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in paragraph (c) of this Section 6.3, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in paragraph (c) of this Section 6.3 with respect to the notice of the threat or commencement of any threat or action shall apply if a claim for contribution is to be made under this paragraph (d); provided, however, that no additional notice shall be required with respect to any threat or action for which notice has been given under paragraph (c) for purposes of indemnification. The Company and the Purchaser agree that it would not be just and equitable if contribution pursuant to this Section 6.3 were determined solely by pro rata allocation (even if the Purchaser 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 in this paragraph. Notwithstanding the provisions of this Section 6.3, no Purchaser shall be required to contribute any amount in excess of the amount by which the Difference exceeds the amount of any damages that such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Purchasers’ obligations to contribute pursuant to this Section 6.3 are several and not joint.

6.4    Information Available. The Company, upon the reasonable request of a Purchaser, shall make available for inspection by such Purchaser, any deemed underwriter participating in any disposition pursuant to the Registration Statement and any attorney, accountant or other agent retained by the Purchasers or any deemed underwriter, all financial and other records, pertinent corporate documents and properties of the Company.

6.5    Delay in Effectiveness of Registration Statement. If (a) a Registration Statement covering the Shares is not declared effective by the Commission on or prior to the Effectiveness Deadline, then for each day following the Effectiveness Deadline until but excluding the date the Commission declares the Registration Statement effective, the Company shall, for each such day, pay each Purchaser with respect to any such failure, as liquidated damages and not as a penalty, an amount per 30-day period equal to 1.0% of the purchase price paid by such Purchaser for its Shares pursuant to this Agreement (calculated on a daily pro rata basis for any portion of such 30-day period prior to the cure of such

17

failure); and for any such 30-day period (or earlier period if such failure is cured prior to 30 days), such payment shall be made no later than three business days following such 30-day period (or earlier period if such failure is cured prior to 30 days). Notwithstanding the foregoing provisions, in no event shall the Company be obligated to pay any liquidated damages pursuant to this Section 6.6 to more than one Purchaser in respect of the same Shares for the same period of time or in an aggregate amount that exceeds 5% of the purchase price paid by the Purchasers for the Shares pursuant to this Agreement. Such payments shall be made to the Purchasers in cash.

SECTION 7.    BROKER’S FEE.

Each of the Company and the Purchasers hereby represents that no broker, investment banker, financial advisor or other individual, corporation, general or limited partnership, limited liability company, firm, joint venture, association, enterprise, joint securities company, trust, unincorporated organization or other entity, other than the Placement Agent, the fees and expenses of which will be paid by the Company, is entitled to any broker’s, finder’s, financial advisor’s financial advisor’s or other similar fee or commission in connection with the transactions contemplated by this Agreement. Each party hereto further agrees to indemnify each other party for any claims, losses or expenses incurred by such other party as a result of the representation in this Section 7 being untrue.

SECTION 8.    COVENANTS.

8.1    Form D; Blue Sky Filings. The Company agrees to file a Form D with respect to the Shares as required under Regulation D of the Securities Act. The Company will take such action as the Company shall reasonably determine is necessary in order to obtain an exemption from, or to qualify the Shares for, sale to the Purchasers at each of the Closings respectively pursuant to this Agreement under applicable securities of “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon the written request of the Purchasers.

8.2    Lock-up. Each Purchaser agrees to comply with the terms of the Lock-up set forth in Exhibit B during the Lock Up Period (as defined in Exhibit B).

8.3    Transfer Taxes. On the Closing Date, all stock transfer or other taxes (other than income taxes) that are required to be paid in connection with the issuance, sale and delivery of the Shares to the Purchasers hereunder will be fully paid or provided for by the Company and all laws imposing such taxes will have been fully complied with and the Purchasers and their respective affiliates shall have no obligation therefor.

8.4    Listing of Common Stock. The Company shall promptly secure the listing of the Shares upon each national securities exchange and automated quotation system that requires an application by the Company for listing, if any, upon which shares of Common Stock are then listed (subject to official notice of issuance) and shall maintain such listing, so long as any other shares of Common Stock shall be so listed. The Company shall use its commercially reasonable efforts to maintain the Common Stock’s listing on the Trading Market. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 8.4.

18
