The Company also proposes to issue and sell to the several Underwriters up to an additional 825,000 shares of its Common Stock, par value $0.01 per share (the “Additional Shares”), if and to the extent that you shall have determined to exercise, on behalf of the Underwriters, the right to purchase such shares of common stock granted to the Underwriters in Section 3 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the “Shares”.

The Company meets the requirements for use of Form S-3 under the Securities Act and the rules and regulations of the Commission thereunder. The Initial Registration Statement and any post-effective amendment thereto, each in the form (excluding exhibits) heretofore delivered to you for your benefit and the benefit of the other Underwriters, have been declared effective by the Commission in such form. Other than a registration statement, if any, increasing the size of the offering (a “Rule 462(b) Registration Statement”), filed pursuant to Rule 462(b) under the Securities Act, which became effective upon filing, the Preliminary Prospectus (as defined below) and the Prospectus (as defined below) contemplated hereby to be filed pursuant to Rule 424(b) under the Securities Act in accordance with Section 4.2 hereof, no other document with respect to the Initial

Registration Statement has heretofore been filed with the Commission or distributed. For purposes of this Agreement: the base prospectus included in the Initial Registration Statement at the time of effectiveness thereof (the “Base Prospectus”), as supplemented by the preliminary prospectus supplement filed with the Commission on May 9, 2007 is referred to as the “Preliminary Prospectus”; the Base Prospectus, as supplemented by the final prospectus supplement relating to the offer and sale of the Shares, in the form filed pursuant to and within the time limits described in Rule 424(b) under the Securities Act is referred to as the “Prospectus”; “the various parts of the Initial Registration Statement and the Rule 462(b) Registration Statement, if any, in each case including all exhibits thereto and including the information contained in the Prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act and deemed by virtue of Rules 430A and 430B under the Securities Act to be part of the Initial Registration Statement at the time it became effective are hereinafter collectively called the “Registration Statements” any reference herein to any Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein as of the effective date of such Registration Statement or the date of the Preliminary Prospectus or Prospectus, as the case may be; any reference to any amendment or supplement to the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after the date of the Preliminary Prospectus or the Prospectus under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and incorporated by reference in the Preliminary Prospectus or Prospectus, as the case may be; the Preliminary Prospectus relating to the Shares that was included in the Registration Statements immediately prior to the Applicable Time (as defined in Section 1.3 hereof), including any document incorporated by reference therein is hereinafter called the “Pricing Prospectus”; any “issuer free writing prospectus” as defined in Rule 433 under the Securities Act relating to the Shares in 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) under the Securities Act, is hereinafter called an “Issuer Free Writing Prospectus”; any Issuer Free Writing Prospectus that is identified on Schedule B to this Agreement is hereinafter called a “General Use Free Writing Prospectus”; and any Issuer Free Writing Prospectus that is not a General Use Free Writing Prospectus is hereinafter called a “Limited Use Free Writing Prospectus.”

The Company and its subsidiaries have good and marketable title to all personal property owned by them which is material to the business of the Company and its subsidiaries, in each case free and clear of all liens, encumbrances and defects except such as are described in the General Disclosure Package and the Prospectus or such as do not materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company and its subsidiaries; and any real property and buildings held under lease by the Company and its subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and its subsidiaries.

1.24. Intellectual Property Rights. The Company and its subsidiaries own or possess, or can acquire on commercially reasonable terms, legally enforceable rights to use all trademarks, service marks, trade names, domain names, copyrights, patents, inventions, know how (including trade secrets and

other unpatented and/or unpatentable proprietary or confidential information, systems or procedures), computer software, and other intellectual property rights (“Intellectual Property”) as are necessary for the conduct of their respective businesses as described in the General Disclosure Package and the Prospectus, except where failure to own, possess or acquire such rights would not have, individually or in the aggregate, a material adverse effect on the Company and its subsidiaries, taken as a whole. Except as described in the General Disclosure Package, (i) to the knowledge of the Company, there is no infringement, misappropriation or violation by third parties of any such Intellectual Property; (ii) there is no pending or, to the knowledge of the Company, threatened action, suit, proceeding or claim by others challenging the Company’s or any of its subsidiaries’ rights in or to any such Intellectual Property; (iii) the Intellectual Property owned by the Company and its subsidiaries and to the knowledge of the Company, the Intellectual Property licensed to the Company and its subsidiaries has not been adjudged invalid or unenforceable, in whole or in part, and there is no pending or threatened action, suit, proceeding or claim by others challenging the validity or scope of any such Intellectual Property; (iv) there is no pending or, to the knowledge of the Company, threatened action, suit, proceeding or claim by others against the Company or any of its subsidiaries that the Company or any of its subsidiaries infringes, misappropriates or otherwise violates any Intellectual Property or other proprietary rights of others, and neither the Company nor any of its subsidiaries has received any written notice of such claim; and (v) to the Company’s knowledge, no employee of the Company or any of its subsidiaries is the subject of any claim or proceeding involving a violation of any term of any employment contract, patent disclosure agreement, invention assignment agreement, non-competition agreement, non-solicitation agreement, nondisclosure agreement or any restrictive covenant to or with a former employer where the basis of such violation relates to such employee’s employment with the Company or any of the Company’s subsidiaries or actions undertaken by the employee while employed with the Company or any of the Company’s subsidiaries, except, in each case, for any instances which would not have, individually or in the aggregate, a material adverse effect on the Company and its subsidiaries, taken as a whole.

The Company and its subsidiaries are insured by the insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which they are engaged. All policies insuring the Company or any of its subsidiaries are in full force and effect and the Company and its subsidiaries, as applicable, are in compliance with the terms of such policies in all material respects. Neither the Company nor any of its subsidiaries has any 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 would not have, individually or in the aggregate, a material adverse effect on the Company and its subsidiaries, taken as a whole.

1.27. Governmental Permits. The Company and its subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal, state or foreign regulatory authorities necessary to conduct their respective businesses, except where the failure to possess any such certificate, authorization or permit would not have, individually or in the aggregate, a material adverse effect on the Company and its subsidiaries, taken as a whole, and neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would have a material adverse effect on the Company and its subsidiaries, taken as a whole.

1.28. Compliance with Laws; No Violations. The Company and each of its subsidiaries is conducting their respective businesses in compliance with applicable federal, state, local and foreign laws, rules and regulations, except where the failure to be so in compliance would not have, individually or in the aggregate, a material adverse effect on the Company and its subsidiaries, taken as a whole. The Company and its subsidiaries are not in breach of, or in default (nor has any event occurred which with notice, lapse of time, or both would result in any breach of, or constitute a default) (i) under their respective certificates of incorporation or by-laws (or analogous governing instruments) or (ii) in the performance or observance of any obligation, agreement, covenant or condition contained in any license, indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness, or any lease, contract or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which they or any of their respective properties are bound, except for any such breach or default which would not have, individually or in the aggregate, a material adverse effect on the Company and its subsidiaries, taken as a whole.

Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company’s counsel, the Company’s accountants in connection with the registration and delivery of the Shares under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statements, the Preliminary Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package, the Prospectus and amendments, supplements and exhibits to, or any document incorporated by reference into, any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified; (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters, including any transfer or other taxes payable thereon; (iii) the cost of printing or producing any Blue Sky or legal investment memorandum in connection with the offer and sale of the Shares under state securities laws and all expenses in connection with the qualification of the Shares for offer and sale under state securities laws as contemplated by Section 4.7 hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky or legal investment memorandum; (iv) all filing fees incurred in connection with the review and qualification of the offering of the Shares by the NASD; (v) all costs and expenses incident to listing the Shares on the Nasdaq Global Market; (vi) the cost of printing certificates representing the Shares; (vii) the costs and charges of any transfer agent, registrar or depositary; (viii) the costs and expenses of (A) any work done in advance on preparing the investor presentation on a “road show” undertaken in connection with the marketing of the offering of the Shares, including expenses associated with the production of road show slides and graphics and fees and expenses of any consultants engaged in connection with the road show presentations, including consultants engaged by the Underwriters with the prior approval of the Company, (B) the lodging costs and expenses of the Company’s representatives and (C) the travel costs and expenses of the Company’s representatives; (ix) all expenses in connection with any offer and sale of the Shares outside of the United States including filing fees in connection with offers and sales outside of the United States; and (x) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section. Notwithstanding the foregoing, the Underwriters shall be responsible for (A) the lodging costs and expenses of their representatives, (B) the travel costs and

expenses of their representatives, (C) the automobile costs and expenses of the representatives and officers of the Company, in each case in connection with the marketing of the offering of the Shares on the road show and (D) all other incidental expenses incurred in connection with the marketing of the offering of the Shares on the road show and not previously addressed above, including group lunches. In addition, notwithstanding anything in this Section 6 to the contrary, all costs and expenses associated with chartering any aircraft in connection with the marketing of the offering of the Shares on the road show shall be borne 50% by the Company and 50% by the Underwriters. It is understood, however, that except as provided in this Section, Section 7 entitled “Indemnity, Contribution and Survival”, and the last paragraph of Section 10 below, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel and any advertising expenses connected with any offers they may make.

7. Indemnity, Contribution and Survival.

7.1. Indemnification of the Underwriters. The Company agrees 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 Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) (i) caused by any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, any Registration Statement or the Prospectus, or in any amendment or supplement thereto or document incorporated by reference therein, or (ii) caused by any omission or alleged omission to state therein a material fact (A) in the case of a Registration Statement or in any amendment or supplement thereto or document incorporated by reference therein, required to be stated therein or necessary to make the statements therein not misleading or (B), in the case of the Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act or the Prospectus, or in any amendment or supplement thereto or document incorporated by reference therein, necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information furnished to the Company in writing by an Underwriter through you expressly for use therein, which information the parties hereto agree is limited to the information listed in Section 21 hereof.

7.2. Indemnification by the Underwriters. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the directors of the Company, the officers of the Company who sign the Registration Statements and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) (i) caused by any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, any Registration Statement or the Prospectus, or in any amendment or supplement thereto or document incorporated by reference therein, or (ii) caused by any omission or alleged omission to state therein a material fact (A) in the case of a Registration Statement or in any amendment or supplement thereto or document incorporated by reference therein, required to be stated therein or necessary to make the statements therein not misleading or (B), in the case of the Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act or the Prospectus, or in any amendment or supplement thereto or document incorporated by reference therein, necessary to make the statements therein, in light of the circumstances under which they were made,

not misleading, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein, which information the parties hereto agree is limited to the information listed in Section 21 hereof.

7.3. Indemnification Procedures. 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 7, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay 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, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (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. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statements and each person, if any, who controls the Company within the meaning of either such Section 15 of the Securities Act or Section 20 of the Exchange Act. In the case of any such separate firm for the Underwriters and such control persons of any Underwriters, such firm shall be designated in writing by Xxxxxx Xxxxxx Partners. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. 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. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. 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 indemnity 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.

7.4. Contribution Agreement. To the extent the indemnification provided for in this Section 7 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause (i) of this

Section 7.4 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 indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

7.5. Contribution Amounts. The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7.4 hereof. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, 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 Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public. 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 remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

7.6. Survival of Provisions. The indemnity and contribution provisions contained in this Section 7 and the covenants, agreements, representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, or any investigation made by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

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

9. Termination. This Agreement shall be subject to termination by notice given by you to the Company, if any of the events, circumstances or conditions described in Section 5.6 or 5.12 hereof shall have occurred. This Agreement shall also be subject to termination in accordance with Section 10 hereof.

10. Defaulting Underwriters. If, on the Closing Date or the Option Closing Date, as applicable, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they

have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule A bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased, and arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven (7) days, in order that the required changes, if any, in the Registration Statements and in the Prospectus or in any other documents or arrangements may be effected. If, on the Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase Additional Shares or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. The term “Underwriter” as used in this Agreement shall include any person who may be substituted for a defaulting Underwriter under this Section with like effect as if such person had originally been a party to this Agreement with respect to Shares to be purchased by such substitute Underwriter.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

11. Counterparts. This Agreement may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

12. Headings; Table of Contents. The headings of the Sections of this Agreement and the table of contents have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

13. Notices. All communications hereunder shall be in writing and shall be mailed, hand delivered, sent by facsimile transmission or telecopied and confirmed to the parties hereto as follows:

The term “successors” shall not include any purchaser of the Shares as such from any of the Underwriters merely by reason of such purchase.

15. Partial Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof. If any Section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum.

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

19. Amendments. This Agreement may only be amended or modified in writing, signed by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit.
