Ladies and Gentlemen:

Roadrunner Transportation Systems, Inc, a Delaware corporation (the “Company”), proposes to issue and sell to the several Underwriters named in Schedule II hereto (the “Underwriters”), and certain stockholders of the Company (the “Selling Stockholders”) named in Schedule I hereto, severally and not jointly and subject to the terms and conditions state herein, propose to sell to the several Underwriters, an aggregate of 10,600,644 shares of the common stock, $.01 par value per share, of the Company (the “Firm Shares”), of which 9,000,000 shares are to be issued and sold by the Company and 1,600,644 shares are to be sold by the Selling Stockholders, each Selling Stockholder selling the number of Firm Shares set forth opposite such Selling Stockholder’s name in Schedule I hereto.

The Company also proposes to issue and sell to the several Underwriters up to an additional 1,590,096 shares of common stock, $.01 par value per share, of the Company (the “Additional Shares”), if and to the extent that you, Robert W. Baird & Co. Incorporated (“Baird”), BB&T Capital Markets, a division of Scott & Stringfellow, LLC (“BB&T”) and Stifel, Nicolaus & Company, Incorporated (together with Baird and BB&T, the “Managers”), as managers of the offering, 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 shares of common stock, $.01 par value per share, of the Company to be outstanding after giving effect to the sales contemplated hereby are hereinafter referred to as the “Common Stock.” The Company and the Selling Stockholders are hereinafter sometimes collectively referred to as the “Sellers.”

The Company has prepared and filed, in accordance with the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations thereunder, with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (registration no. 333-152504), including a form of prospectus, relating to the Shares. The registration statement, as amended at the time it becomes effective, including the exhibits and documents filed as part thereof and information contained in the prospectus filed as part of the registration

statement pursuant to Rule 424 or otherwise deemed to be part of the registration statement pursuant to Rule 430A or 430C under the Securities Act, is hereinafter referred to as the “Registration Statement.” If the Company files an abbreviated registration statement to register additional shares of Common Stock pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. The Company has also filed with, or transmitted for filing to, or shall promptly after the date of this Agreement file with or transmit for filing to, the Commission pursuant to Rule 424(b) under the Act a final prospectus (in the form first used to confirm sales of the Shares (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act), the “Prospectus”) that meets the requirements of Section 10(a) of the Securities Act. The term “Preliminary Prospectus,” as of any time, means any preliminary form of prospectus included in the Registration Statement immediately prior to such time or filed with the Commission pursuant to Rule 424(a) under the Securities Act at such time, that omits certain information as permitted by Rule 430A(a). The “Preliminary Prospectus” without reference to a time means the Preliminary Prospectus included in the Registration Statement or deemed a part of the Registration Statement pursuant to Rule 430A under the Securities Act immediately prior to the Time of Sale (as defined below).

For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act; “Time of Sale Prospectus” means the Preliminary Prospectus, together with the free writing prospectuses, if any, each identified in Schedule III hereto (each, a “Permitted Free Writing Prospectus”), and other information conveyed to purchasers of the Shares at or prior to the Time of Sale as set forth in Schedule III hereto; “Time of Sale” means 6:00 p.m. (Central Time) on the date of this Agreement; “road show” has the meaning set forth in Rule 433(h)(4) under the Securities Act, and “bona fide electronic road show” has the meaning set forth in Rule 433(h)(5) under the Securities Act.

The Company has also prepared and filed, in accordance with Section 12 of the Securities Exchange Act of 1934 (the “Exchange Act”), a registration statement on Form 8-A (file no. 001-34734) to register the Common Stock under Section 12(b) of the Exchange Act.

The Managers have agreed to reserve a portion of the Shares to be purchased by them under this Agreement for sale to the Company’s directors, officers, employees and business associates and other parties related to the Company (collectively, “Participants”), as set forth in the Prospectus under the heading “Underwriters” (the “Directed Share Program”). The Shares to be sold by the Managers and their respective affiliates pursuant to the Directed Share Program are referred to hereinafter as the “Directed Shares.” Any Directed Shares not orally confirmed for purchase by any Participant by the end of the business day on which this Agreement is executed will be offered to the public by the Underwriters as set forth in the Prospectus.

In connection with the consummation of the public offering of the Shares contemplated in this Agreement, the Company has amended the Certificate of Incorporation of the Company (the “Certificate Amendment”) to provide for (i) the split on a 149.314-for-one basis of the Company’s Class A Voting Common Stock (“Class A Common Stock”), Class B Non-Voting Common Stock (“Class B Common Stock”) and Series B Convertible Preferred Stock (“Series B Preferred Stock”), effective May 7, 2010, and (ii) the conversion on a one-for-one basis of the shares of Class A Common Stock, Class B Common Stock and Series B Preferred Stock into a newly authorized class of common stock, $.01 par value per share, of the Company immediately prior to the consummation of the public offering of the Shares contemplated in this Agreement. The Certificate Amendment, the stock split and the conversion are described in the Preliminary Prospectus under “Description of Capital Stock” and the stock split and the conversion are collectively referred to in this Agreement as the “Recapitalization Transactions.”

The Company’s subsidiary, GTS Transportation Logistics, Inc., a Delaware corporation (“Acquisition Sub”), intends to merge with Group Transportation Services Holdings, Inc. (“GTS”), a Delaware corporation, simultaneously with the public offering of the Shares contemplated in this Agreement (the “GTS Merger”). In connection with the GTS Merger, the Company, Acquisition Sub and GTS have entered into an Agreement and Plan of Merger, dated May 7, 2010 (the “GTS Merger Agreement”). The consummation of the GTS Merger shall occur as of the Closing Date referred to in Section 5 hereof. For purposes of the representations and warranties of the Company set forth in Section 1 hereof, and the opinions to be delivered pursuant to Section 6(d) hereof, the surviving corporation of the GTS Merger shall be deemed for all purposes to be a subsidiary of the Company.

Except as described in the Time of Sale Prospectus, since the end of the Company’s most recent audited fiscal year, there has been (i) no significant deficiency or material weakness in the design or operation of the Company’s internal control over financial reporting (whether or not remediated) which is reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information, and (ii) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Company and each Selling Stockholder at the Purchase Price the number of Firm Shares (subject to such adjustments to eliminate fractional shares as the Managers may determine) set forth opposite the name of such Underwriter set forth in Schedule II hereto that bears the same proportion to the number of Firm Shares to be sold by each such Seller as the number of Firm Shares set forth in Schedule II hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

Moreover, the Company hereby agrees to issue and sell up to 1,590,096 Additional Shares to the Underwriters at the Purchase Price and the Underwriters, upon the basis of the representations and warranties contained herein, but subject to the terms and conditions herein set forth, shall have the right (but not the obligation) to purchase, severally and not jointly, up to the Additional Shares at the Purchase Price.

Each Selling Stockholder agrees to advise the Managers promptly, and if requested by the Managers, confirm such advice in writing, so long as delivery of a prospectus relating to the Shares by an underwriter or dealer may be required under the Securities Act, any change in information contained in the Registration Statement, the Time of Sale Prospectus or the Prospectus that relates to such Selling Stockholder.

4. Terms of Public Offering.

The Sellers are further advised by the Managers that the Shares are to be offered to the public initially at $14.00 per share (the “Public Offering Price”) and to certain dealers selected by the Managers at a price that represents a concession not in excess of $0.588 per share under the Public Offering Price, and that any Underwriter may allow, and such dealers may reallow a concession, not in excess of $0.10 per share, to any Underwriter or to certain other dealers.

5. Payment and Delivery. Payment for the Firm Shares to be sold by each Seller shall be made to such Seller (or to accounts otherwise designated by such Seller and agreed to by the Underwriters) in Federal or other funds immediately available in Milwaukee against delivery of such Firm Shares for the respective accounts of the several Underwriters at 10:00 a.m., Central Time, on May 18, 2010 or at such other time on the same or such other date as shall be agreed to by the parties hereto.

any such consultants (it being agreed that the Company will not be responsible for the travel and food expenses of the officers or the Chairman of the Board of the Company (except as specifically noted herein with respect to the cost of any chartered aircraft) or the Underwriters’ travel, food and lodging expenses), and one-half of the cost of any aircraft chartered in connection with the road show, (ix) the document production charges and expenses associated with printing this Agreement, (x) all expenses in connection with any offer and sale of the Shares outside of the United States, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with offers and sales outside of the United States, (xi) all fees and disbursements of counsel incurred by the Underwriters in connection with the Directed Share Program and stamp duties, similar taxes or duties or other taxes, if any, incurred by the Underwriters in connection with the Directed Share Program, and (xii) 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; provided, however, that the liability of the Company for reasonable fees and disbursements of counsel for the Underwriters pursuant to clauses (iii), (iv), (x) and (xi) shall not exceed $5,000 in the aggregate.

Whether or not the sale of the Shares provided for herein is consummated, each Selling Stockholder will pay or cause to be paid all costs and expenses incident to the performance of such Selling Stockholder’s obligations hereunder which are not otherwise specifically provided for in this Section 8, including (i) any fees and expenses of counsel for such Selling Stockholder, and (ii) all expenses and taxes incident to the sale and delivery of the Shares to be sold by such Selling Stockholder to the Underwriters hereunder.

Except as expressly set forth herein, the Underwriters will pay all of their own costs and expenses, including fees and disbursements of their counsel, stock transfer taxes payable on resale of any of the Shares by them and any advertising expenses connected with any offers they may make. Notwithstanding the above, if the sale of the Shares provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 (except Section 6(f) and Section 6(k)) is not satisfied, because of any termination of this Agreement by the Underwriters pursuant to Section 11 hereof or because of any refusal, inability or failure on the part of the Company to perform any obligation or covenant hereunder or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, through the Managers on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereby.

The provisions of this Section shall not supersede or otherwise affect any agreement that the Sellers may otherwise have for the allocation of such expenses among themselves.

9. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, 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, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities 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) caused by, arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any issuer information that the Company has filed, or is required to file, pursuant to Rule 433(d) of the Securities Act, any road show not constituting a free writing prospectus, or the Prospectus or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company shall not be liable under this Section 9(a) to the extent that such losses, claims, damages or liabilities are caused by, arise out of or are based upon any such untrue statement or omission or alleged untrue statement or omission made therein in reliance upon and in conformity with information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Managers expressly for use therein, it being agreed that the only information furnished by the Underwriters to the Company expressly for use therein are the concession and reallowance figures appearing in the fifth paragraph, and the name of each Underwriter and the number of Shares each Underwriter has agreed to purchase, as set forth in the table following the first paragraph, each in the “Underwriting” section of the Preliminary Prospectus and the Prospectus.

(b) Each Selling Stockholder agrees, severally and not jointly, to indemnify and hold harmless each Underwriter, 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, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities 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) caused by, arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, or any amendment or supplement thereto, or any

omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which there were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or omission or alleged untrue statement or omission was made therein in reliance upon and in conformity with information relating to such Selling Stockholder furnished in writing by or on behalf of such Selling Stockholder expressly for use therein. The Underwriters and each Selling Stockholder agree that the indemnity agreement contained in this clause (b) shall not apply to amounts paid in settlement of any loss, claim, damage, liability, action or proceeding if such settlement is effected without the consent of such Selling Stockholder. The liability of each Selling Stockholder under this Section 9(b) shall be limited to an amount equal to the net proceeds (before expenses) from the offering of the Shares received by such Selling Stockholder under this Agreement.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the Selling Stockholders, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or any Selling Stockholder 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) caused by, arising from or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) of the Securities Act, any road show not constituting a free writing prospectus, or the Prospectus or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which there were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or omission or alleged untrue statement or omission was made therein in reliance upon and in conformity with information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Managers expressly for use therein, it being agreed that the only information furnished by the Underwriters to the Company expressly for use therein are the concession and reallowance figures appearing in the fifth paragraph, and the name of each Underwriter and the number of Shares each Underwriter has agreed to purchase, as set forth in the table following the first paragraph, each in the “Underwriting” section of the Preliminary Prospectus and the Prospectus.

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a), 9(b) or 9(c), 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 reasonable 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 or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (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 Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Stockholders and all persons, if any, who control any Selling Stockholder within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by Baird. 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. In the case of any such separate firm for the Selling Stockholders and such control persons of any Selling Stockholders, such firm shall be designated in writing by the persons named as attorneys-in-fact for the Selling Stockholders under the Powers of Attorney. 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 30 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.

(e) To the extent the indemnification provided for in Sections 9(a), 9(b) or 9(c) 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) 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 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 Sellers 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 each Seller 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 Sellers 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 Sellers 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 9 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. The liability of each Selling Stockholder under the contribution agreement contained in this paragraph shall be limited to an amount equal to the net proceeds (before expenses) from the offering of the Shares received by such Selling Stockholder under this Agreement. Notwithstanding the foregoing provisions of subsection (e), no Selling Stockholder shall be required to contribute unless such Selling Stockholder would have had indemnification obligations pursuant to Section 9(b) above.

(f) The Sellers and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 9 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 9(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(e) 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 9, 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 exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 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.

10. Directed Share Program Indemnification. (a) The Company agrees to indemnify and hold harmless each Underwriter, 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 and each affiliate of either of any Underwriter within the meaning of Rule 405 of the Securities Act (the “Underwriter Entities”) 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 any material prepared by or with the consent of the Company for distribution to Participants in connection with the Directed Share Program or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) caused by the failure of any Participant to pay for and accept delivery of Directed Shares that the Participant agreed to purchase; or (iii) related to, arising out of, or in connection with the Directed Share Program, other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of the Underwriter Entities.

(b) In case any proceeding (including any governmental investigation) shall be instituted involving any Underwriter Entity in respect of which indemnity may be sought pursuant to Section 10(a), the Underwriter Entity seeking indemnity, shall promptly notify the Company in writing and the Company, upon request of the Underwriter Entity, shall retain counsel reasonably satisfactory to the Underwriter Entity to represent the Underwriter Entity and any others the Company may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any Underwriter Entity shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Underwriter Entity unless (i) the Company shall have agreed to the retention of such counsel or (ii) the

named parties to any such proceeding (including any impleaded parties) include both the Company and the Underwriter Entity and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Company shall not, in respect of the legal expenses of the Underwriter Entities in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriter Entities. Any such separate firm for the Underwriter Entities shall be designated in writing by Baird. The Company 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 Company agrees to indemnify the Underwriter Entities from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time a Underwriter Entity shall have requested the Company to reimburse it for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the Company 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 30 days after receipt by the Company of the aforesaid request and (ii) the Company shall not have reimbursed the Underwriter Entity in accordance with such request prior to the date of such settlement. The Company shall not, without the prior written consent of Baird, effect any settlement of any pending or threatened proceeding in respect of which any Underwriter Entity is or could have been a party and indemnity could have been sought hereunder by such Underwriter Entity, unless such settlement includes an unconditional release of the Underwriter Entities from all liability on claims that are the subject matter of such proceeding.

(c) To the extent the indemnification provided for in Section 10(a) is unavailable to a Underwriter Entity or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the Company in lieu of indemnifying the Underwriter Entity thereunder, shall contribute to the amount paid or payable by the Underwriter Entity as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter Entities on the other hand from the offering of the Directed Shares 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 of the Underwriter Entities on the other hand in connection with any 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 Underwriter Entities on the other hand in connection with the offering of the Directed Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Directed Shares (before deducting expenses) and the total underwriting discounts and commissions received by the Underwriter Entities for the Directed Shares, bear to the aggregate Public Offering Price of the Directed Shares. If the loss, claim, damage or liability is caused by an untrue or alleged untrue statement of a material fact or the omission or alleged omission to

state a material fact, the relative fault of the Company on the one hand and the Underwriter Entities on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement or the omission or alleged omission relates to information supplied by the Company or by the Underwriter Entities and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(d) The Company and the Underwriter Entities agree that it would not be just or equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the Underwriter Entities 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 10(c). The amount paid or payable by the Underwriter Entities 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 the Underwriter Entities in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10, no Underwriter Entity shall be required to contribute any amount in excess of the amount by which the total price at which the Directed Shares distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter Entity has otherwise been required to pay. The remedies provided for in this Section 10 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.

11. Termination. The Underwriters may terminate this Agreement by notice given by the Managers to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (a) trading generally shall have been suspended or materially limited or minimum prices shall have been established on, or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, or the NASDAQ Stock Market, (b) trading of any securities of the Company shall have been suspended or materially limited on any exchange or in any over-the-counter market, (c) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (d) any moratorium or material limitation on commercial banking activities shall have been declared by Federal, Wisconsin or New York state authorities, (e) there shall have occurred any outbreak or escalation of hostilities, act of terrorism involving the United States or declaration by the United States of a national emergency or war, or (f) any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (e) or (f), in the Managers’ judgment, is material and adverse and makes it, in the Managers’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus (exclusive of any supplement thereto).

12. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, 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 II 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 the Managers 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 12 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 on such date, and arrangements satisfactory to the Managers, the Company and the Selling Stockholders 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, the Company or the Selling Stockholders. In any such case either the Managers or the relevant Sellers shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an 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 on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date 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.

13. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company, each Selling Stockholder and the Underwriters set forth or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any Selling Stockholder or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 9 and 10 hereof, and will survive delivery of and payment for the Shares. The provisions of Sections 8, 9 and 10 hereof shall survive the termination or cancellation of this Agreement.

14. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other, with respect to the preparation of any Preliminary Prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company and the Selling Stockholders acknowledge that in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company, any Selling Stockholder or any other person; (ii) the Underwriters owe the Company and Selling Stockholders only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any; and (iii) the Underwriters may have interests that differ from those of the Company. Each of the Company and Selling Stockholders waives to the full 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 Shares.

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

16. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Wisconsin.

17. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.
