Ladies and Gentlemen:

Rockwell Medical Technologies, Inc., a Michigan corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell to the several underwriters named in Schedule I hereto (collectively, the “Underwriters”) for whom Xxxxxx, Xxxxxxxx & Company, Incorporated is acting as representative (the “Representative”), an aggregate of 1,845,000 shares (the “Shares”) of common stock, no par value per share, of the Company (the “Common Stock”).

1. The Company represents and warrants to, and agrees with, each of the Underwriters that (unless the context shall clearly indicate otherwise, any reference in Section 1 to the Company shall include its Subsidiary (defined below)):

(a) The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333 160791), and such amendments to such registration statement as may have been required to the date of this Agreement, under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations (the “Rules and Regulations”) of the Commission thereunder. Such registration statement, at any given time, including any amendments thereto to such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act at such time and the documents and information otherwise deemed to be a part thereof or included therein by Rule 430B under the Securities Act (the “Rule 430B Information”) or otherwise pursuant to the Rules and Regulations at such time, is herein called the “Registration Statement.” The Registration Statement at the time it originally became effective is herein called the “Initial Registration Statement.”

The prospectus in the form in which it appeared in the Initial Registration Statement is herein called the “Base Prospectus.” Each preliminary prospectus supplement, if any, to the Base Prospectus (including the Base Prospectus as so supplemented) that described the Shares and the offering thereof, that omitted the Rule 430B Information and that was used prior to the filing of the final prospectus

supplement referred to in the following sentence is herein called a “Preliminary Prospectus.” Promptly after the execution and delivery of this Agreement, the Company will prepare and file with the Commission a final prospectus supplement to the Base Prospectus relating to the Shares and the offering thereof in accordance with the provisions of Rule 430B and Rule 424(b) of the Rules and Regulations. Such final supplemental form of prospectus (including the Base Prospectus as so supplemented), in the form filed with the Commission pursuant to Rule 424(b) under the Securities Act is herein called the “Prospectus.” Any reference herein to the Base Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act as of the date of such prospectus.

For purposes of this Agreement, all references to the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“XXXXX”). All references in this Agreement to financial statements and schedules and other information that is “described,” “contained,” “included” or “stated” in the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information that is incorporated by reference in or otherwise deemed by the Rules and Regulations to be a part of or included in the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to mean and include the subsequent filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and which is deemed to be incorporated by reference therein or otherwise deemed by the Rules and Regulations to be a part thereof.

(b) At the time of the filing of the Initial Registration Statement with the Commission, the conditions for use of Form S-3, set forth in the General Instructions thereto, were satisfied. The Initial Registration Statement was declared effective by the Commission under the Securities Act on August 17, 2009. The Company has complied, to the Commission’s satisfaction, with all requests of the Commission for additional or supplemental information. No stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto has been issued, and, to the Company’s knowledge, no proceeding for that purpose has been initiated or threatened by the Commission.

(c) For the purposes of this Agreement, the “Applicable Time” is 5:00 p.m. (Eastern time) on the date of this Agreement. The Disclosure Package (as defined below) at the Applicable Time complied in all material respects with the requirements of the Securities Act and the Rules and Regulations and did not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements or omissions from the Disclosure Package made in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representative expressly for use therein; it being understood and agreed that the only such information furnished by or on behalf of any Underwriter through the Representative consists of the information described as such in Section 10(f).

(d) Each part of the Registration Statement and any post-effective amendment thereto, at the time that such part became effective (including each deemed effective date with respect to the Underwriters pursuant to Rule 430B or otherwise under the Securities Act), at all other subsequent times until the expiration of the Prospectus Delivery Period (as defined below), and at the Time of

Delivery (as defined below), and the Prospectus, at the time of filing or the time of first use within the meaning of the Rules and Regulations, at all subsequent times until expiration of the Prospectus Delivery Period, and at the Time of Delivery, complied and will comply in all material respects with the applicable requirements and provisions of the Securities Act, the Rules and Regulations and the Exchange Act and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Prospectus, as amended or supplemented, as of its date, or the time of first use within the meaning of the Rules and Regulations, at all subsequent times until the expiration of the Prospectus Delivery Period, and at the Time of Delivery, did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties set forth in the two immediately preceding sentences do not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, or the Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representative expressly for use therein; it being understood and agreed that the only such information furnished by or on behalf of any Underwriter through the Representative consists of the information described as such in Section 10(f).

(e) Neither (i) any Issuer General Free Writing Prospectus(es) issued at or prior to the Applicable Time and set forth on Schedule II, the Statutory Prospectus at the Applicable Time and the information set forth on Schedule III at the Applicable Time, all considered together (collectively, the “Disclosure Package”); nor (ii) any individual Issuer Limited-Use Free Writing Prospectus, when considered together with the Disclosure Package, includes or included as of the Applicable Time any untrue statement of a material fact or omits or omitted as of the Applicable Time to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties set forth in the immediately preceding sentence do not apply to statements in or omissions from any Statutory Prospectus or any Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representative expressly for use therein; it being understood and agreed that the only such information furnished by or on behalf of any Underwriter through the Representative consists of the information described as such in Section 10(f). As used in this paragraph and elsewhere in this Agreement:

(i) “Statutory Prospectus” means the Base Prospectus, as amended and supplemented immediately prior to the Applicable Time, including any document incorporated by reference therein and any prospectus supplement deemed to be a part thereof, including the final prospectus supplement dated the date hereof. For purposes of this definition, Rule 430B Information contained in a form of prospectus that is deemed retroactively to be a part of the Registration Statement shall be considered to be included in the Statutory Prospectus as of the actual time that form of prospectus is filed with the Commission pursuant to Rule 424(b) under the Securities Act.

(ii) “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act, relating to the Shares that (A) is required to be filed with the Commission by the Company; or (B) is exempt from filing pursuant to Rule 433(d)(5)(i) under the Securities Act because it contains a description of the Shares or of the offering that does not reflect the final terms, or is a “bona fide electronic roadshow,” as defined in Rule 433 of the Rules and Regulations, in each case 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.

(iii) “Issuer General Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its being specified in Schedule II hereto.

(iv) “Issuer Limited-Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is not an Issuer General Free Writing Prospectus.

(f) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the Prospectus Delivery Period or until any earlier date that the Company notified or notifies the Underwriters as described in Section 7(c), did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, any Statutory Prospectus or the Prospectus. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representative expressly for use therein; it being understood and agreed that the only such information furnished by or on behalf of any Underwriter through the Representative consists of the information described as such in Section 10(f).

(g) Each Issuer Free Writing Prospectus satisfied, as of its issue date and at all subsequent times through the Prospectus Delivery Period, all other conditions to use thereof as set forth in Rules 164 and 433 under the Securities Act.

(h) The documents incorporated by reference in the Disclosure Package and in the Prospectus, when they became effective or were filed with the Commission, as the case may be, conformed in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, and were filed on a timely basis with the Commission, and none of such documents contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; any further documents so filed and incorporated by reference in the Disclosure Package or in the Prospectus, when such documents are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act, and will not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(i) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Michigan, with corporate power and authority to own its properties and conduct its business as currently being conducted and as described in the Registration Statement, the Disclosure Package and the Prospectus, and is duly qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification, except where the failure to be so qualified in any such jurisdiction would not reasonably be expected to have a material adverse effect on the business, prospects, operations, assets, financial condition, stockholders’ equity or results of operations of the Company (a “Material Adverse Effect”). Complete and correct copies of the charter and bylaws of the Company and all amendments thereto have been made available to the Underwriters, and no changes therein will be made on or after the date hereof through and including the Time of Delivery.

(j) The Company has no subsidiaries (as defined under the Securities Act) other than Rockwell Transportation, Inc., a Michigan corporation (the “Subsidiary”). The Company owns all of the issued and outstanding capital stock of the Subsidiary. Other than the capital stock of the Subsidiary, and other than with respect to its cash equivalents (as defined in the Notes to Consolidated Financial

Statements included in the Company’s financial statements included in the most recent quarterly report on Form 10-Q filed by the Company with the Commission), the Company does not own, directly or indirectly, any shares of stock or any other equity interests or long-term debt securities of any corporation, firm, partnership, joint venture, association or other entity. Complete and correct copies of the charters and bylaws of the Subsidiary and all amendments thereto have been delivered to the Underwriters, and no changes therein will be made on or after the date hereof through and including the Time of Delivery. The Subsidiary has been duly organized and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, with full corporate power and authority to own, lease and operate its properties and to conduct its business, except where failure to be in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Subsidiary is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the ownership or leasing of its properties or the conduct of its business requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. All of the outstanding shares of capital stock of the Subsidiary have been duly authorized and validly issued, are fully paid and non-assessable, have been issued in material compliance with all applicable securities laws, were not issued in violation of any preemptive right, resale right, right of first refusal or similar right and are owned by the Company subject to no security interest, other encumbrance or adverse claims. No options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligation into shares of capital stock or ownership interests in the Subsidiary are outstanding.

(k) The Company had the authorized and outstanding capitalization as set forth in the Registration Statement, the Disclosure Package and the Prospectus, in each case as of the date set forth therein, and all of the issued shares of capital stock of the Company have been duly authorized and validly issued, are fully paid and non-assessable, have been issued in compliance with all federal and state securities laws, were not issued in violation of or subject to any preemptive rights or other rights to subscribe for or purchase securities that have not been waived in writing (a copy of which applicable to the Shares has been delivered to counsel to the Underwriters) and conform in all material respects to the description thereof contained in the Registration Statement, the Disclosure Package and the Prospectus under the caption “Description of Capital Stock.” Except as otherwise described in the Registration Statement, the Disclosure Package and the Prospectus, there are no preemptive rights or other rights to subscribe for or to purchase, or any restriction upon the voting or transfer of, any shares of Common Stock pursuant to the Company’s charter, bylaws or any agreement or other instrument to which the Company is a party or by which the Company is bound. Except as described in the Registration Statement, the Disclosure Package and the Prospectus, neither the filing of the Registration Statement nor the offering or sale of the Shares as contemplated by this Agreement gives rise to any rights for or relating to the registration of any shares of Common Stock or other securities of the Company that have not been fully complied with or previously waived. Except as described or contemplated in the Registration Statement, the Disclosure Package and the Prospectus, there are no options, warrants, agreements, contracts or other rights in existence to purchase or acquire from the Company any shares of the capital stock of the Company (other than as a result of the grant of stock options under the Company’s existing equity incentive plans after the date(s) set forth in the Registration Statement, the Disclosure Package and the Prospectus). The description of the Company’s stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted thereunder, set forth in the Disclosure Package and the Prospectus accurately and fairly presents the information required to be shown with respect to such plans, arrangements, options and rights.

(l) The Shares have been duly authorized and, when issued and delivered against payment therefor as provided herein, will be validly issued and fully paid and non-assessable and free of statutory and contractual preemptive rights, resale rights, rights of first refusal and similar rights and of any restriction upon the voting or transfer thereof pursuant to the Michigan Business Corporation Act or the Company’s charter or bylaws or any agreement or other instrument to which the Company is a party. The Shares will conform in all material respects to the description of the Shares contained in the Registration Statement, the Disclosure Package and the Prospectus under the caption “Description of Capital Stock.”

(o) This Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid, legal and binding obligation of the Company, enforceable in accordance with its terms, except as rights to indemnification or contribution hereunder may be limited by federal or state securities laws and except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally and subject to general principles of equity.

All corporate actions (including those of stockholders) necessary for the Company to consummate the transactions contemplated in this Agreement have been obtained and are in effect. The approval of the Company’s stockholders is not required under the rules and regulations of any trading market for the Company to issue and deliver to the Underwriters the Shares.

Except as described in the Disclosure Package and the Prospectus, the Company has not incurred any material liabilities or obligations, direct or contingent, entered into any material transactions, or declared or paid any dividends or made any distribution of any kind with respect to its capital stock.

Except as set forth in the Registration Statement, the Disclosure Package or the Prospectus: (i) to the knowledge of the Company, there is no infringement, misappropriation or violation by third parties of any such Intellectual Property, except as such infringement, misappropriation or violation would not reasonably be expected to have a Material Adverse Effect; (ii) there is no pending or, to the knowledge of the Company, threatened action, suit, proceeding or claim by others challenging the Company’s rights in or to any such Intellectual Property, and the Company is unaware of any facts which would form a reasonable basis for any such claim; (iii) the Intellectual Property owned by the Company and to the knowledge of the Company, the Intellectual Property licensed to the Company have 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, and the Company is unaware of any facts which would form a reasonable basis for any such claim; (iv) there is no pending or, to the knowledge of the Company, threatened action, suit, proceeding or claim by others that the Company infringes, misappropriates or otherwise violates any Intellectual Property or other proprietary rights of others, the Company has not received any written notice of such claim and the Company is unaware of any other fact which would form a reasonable basis for any such claim; and (v) to the Company’s knowledge, no employee of the Company is in or has ever been in 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 actions undertaken by the employee while employed with the Company, except where such violation would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(bb) The Company carries, or is covered by, insurance issued by insurers of nationally recognized financial responsibility in such amounts and covering such risks as is adequate for the conduct of its business and the value of its properties and as is customary for companies engaged in similar businesses in similar industries; and the Company has not (i) received written notice from any insurer or agent of such insurer that capital improvements or other expenditures are required or necessary to be made in order to continue such insurance; or (ii) 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 at reasonable cost from similar insurers as may be necessary to continue its business. All such insurance is outstanding and in force on the date hereof.

(cc) The Company has timely filed all federal, state, local and foreign income and franchise tax returns required to be filed and is not in default in the payment of any taxes which were payable pursuant to said returns or any assessments with respect thereto, other than any that the Company is contesting in good faith, except for such returns, taxes and assessments the failure of which to file or pay would not reasonably be expected to have a Material Adverse Effect. There is no pending dispute with any taxing authority relating to any of such returns, and the Company has not received written notice of any proposed liability for any material tax to be imposed upon the properties or assets of the Company for which there is not an adequate reserve reflected in accordance with generally accepted accounting principles in the United States (“GAAP”) in the Company’s financial statements included in the Registration Statement, the Disclosure Package and the Prospectus.

There are no current or pending legal, governmental or regulatory actions, suits or proceedings that are required to be described in the Registration Statement, the Disclosure Package and the Prospectus that have not been so described.

(h) On or after the Applicable Time there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange, the NASDAQ Global Select Market, the NASDAQ Global Market, the NASDAQ Capital Market or the NYSE Amex; (ii) a suspension or material limitation in trading in the Company’s securities on the NASDAQ Global Market; (iii) a general moratorium on commercial banking activities declared by either Federal, Michigan or New York state authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; or (v) the occurrence of 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 (iv) or (v) in the Representative’s judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares being delivered at the Time of Delivery on the terms and in the manner contemplated in the Disclosure Package or the Prospectus;

(i) The Shares to be sold at the Time of Delivery shall have been duly listed for quotation on the NASDAQ Global Market;

(n) The Underwriters shall have received at the Time of Delivery a certificate of the Secretary of the Company certifying as to (i) the Company’s charter, (ii) the Company’s bylaws and (iii) the resolutions of the Board of Directors of the Company authorizing the filing of the Registration Statement, the execution and delivery of this Agreement and all other matters related thereto; and

(o) The Company shall have furnished to the Underwriters such additional documents, certificates and evidence as the Underwriters may have reasonably requested to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained, or otherwise in connection with the offering of the Shares contemplated hereby.

Except as otherwise stated herein, all such opinions, certificates, letters and other documents mentioned above and elsewhere in this Agreement will be in compliance with the provisions hereof only if they are reasonably satisfactory in form and substance to the Underwriters and their counsel. The Company will furnish the Underwriters with such conformed copies of such opinions, certificates, letters and other documents as the Underwriters shall reasonably request.

10. (a) The Company will indemnify and hold harmless each Underwriter from and against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the 430B Information and any other information deemed to be part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to the Rules and Regulations, if applicable, any Preliminary Prospectus, the Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, 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 therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representative expressly for use therein; it being understood and agreed that the only such information furnished by or on behalf of any Underwriter through the Representative consists of the information described as such in Section 10(f) and will reimburse the Underwriters for any legal or other expenses reasonably incurred by the Underwriters in connection with investigating or defending any such action or claim as such expenses are incurred.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Disclosure Package, the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, 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 therein not misleading, 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, any Preliminary Prospectus, the Disclosure Package, the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representative expressly for use therein; it being understood and agreed that the only such information furnished by or on behalf of any Underwriter through the Representative consists of information described as such in Section 10(f); and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party except to the extent that such indemnifying party has been materially prejudiced by such failure. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party) and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim; and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 10 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations

referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section 10 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Securities Act; and the obligations of any Underwriter under this Section 10 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to director of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company), to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Securities Act.

(f) Each Underwriter confirms and the Company acknowledges that the statements with respect to the public offering of the Shares by the Underwriters set forth in the fourth paragraph under the caption “Underwriting”, the first paragraph under the caption “Underwriting – Commissions and Discounts”, the paragraph under the caption “Underwriting – Passive Market-Making”, and the paragraphs under the caption “Underwriting – Short Sales, Stabilizing Transactions and Penalty Bids” in the Disclosure Package and in the Prospectus are correct and constitute the only information concerning the Underwriters furnished in writing to the Company by or on behalf of any Underwriter through the Representative expressly for use in the Registration Statement, any Preliminary Prospectus, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus.

11. The Underwriters shall have the right to terminate this Agreement by giving notice to the Company as hereinafter specified at any time at or prior to the Time of Delivery, if (a) any condition of the Underwriters’ obligations hereunder is not fulfilled; (b) trading on the New York Stock Exchange, the NASDAQ Global Select Market, the NASDAQ Global Market, the NASDAQ Capital Market or the NYSE Amex shall have been suspended; (c) a banking moratorium shall have been declared by federal or state authorities; or (d) there shall have occurred any outbreak or escalation of hostilities, any change in financial markets or any calamity or crisis that, in the Representative’s judgment, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Shares. Any such termination shall be without liability of any party to any other party except that the provisions of Section 8 and Section 10 hereof shall at all times be effective and shall survive such termination. If the Underwriters elect to terminate this Agreement as provided in this Section 11, the Company shall be notified promptly by the Underwriters by telephone, confirmed by letter.

12. (a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at the Time of Delivery, the Representative may in its discretion arrange for another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representative does not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of thirty-six hours within which to

procure another party or other parties reasonably satisfactory to the Representative to purchase such Shares on such terms. In the event that, within the respective prescribed periods, the Representative notifies the Company that the Representative has so arranged for the purchase of such Shares, or the Company notifies the Representative that the Company has so arranged for the purchase of such Shares, the Representative or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement, the Disclosure Package or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement, the Disclosure Package or the Prospectus which in the Representative’s opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representative and the Company as provided in subsection (a) above, the aggregate number of such Shares which remain unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at the Time of Delivery, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at the Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representative and the Company as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all of the Shares to be purchased at the Time of Delivery (other than by reason of any default on the part of the Company), or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then the Company will have the right, by written notice given within the following 36-hour period to the Representative, to terminate this Agreement.

13. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Shares.

14. If this Agreement shall be terminated pursuant to Section 12(c) hereof, the Company shall not then be under any liability to any Underwriter except as provided in Sections 10 and 14 hereof; but, except as otherwise provided in this Agreement, if for any other reason any Shares are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters for all out-of-pocket expenses, including, without limitation, fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company shall then be under no further liability to any Underwriter in respect of the Shares not so delivered, except as provided in Sections 10 and 14 hereof.

15. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, electronic or facsimile transmission to the Representative as follows: Xxxxxx, Xxxxxxxx & Company, Incorporated, Xxx Xxxxxxxxxx Xxxxxx, Xxxxx 0000, Xxx Xxxxxxxxx, Xxxxxxxxxx 00000, Attention: General Counsel; and if to the Company shall be delivered or sent by mail, electronic or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Secretary. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

16. In all dealings hereunder, the Representative shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representative.

17. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters and the Company and, to the extent provided in Sections 10 and 13 hereof, the officers and directors of the Company and each person who controls the Company, each person who controls any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

18. Time shall be of the essence of this Agreement.

19. This Agreement may not be amended or modified unless in writing 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. The Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

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

21. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

22. Notwithstanding anything herein to the contrary, the Company is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction contemplated by this Agreement and all materials of any kind (including, without limitation, tax opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

Ladies and Gentlemen:

The undersigned refers to the proposed Underwriting Agreement (the “Underwriting Agreement”) among Rockwell Medical Technologies, Inc., a Michigan corporation (the “Company”), and the several underwriters named therein (the “Underwriters”), for whom Xxxxxx, Xxxxxxxx & Company, Incorporated is acting as Representative. As an inducement to the Underwriters to execute the Underwriting Agreement in connection with the proposed public offering of shares of the Company’s common stock, no par value per share (“Common Stock”), pursuant to a Registration Statement on Form S-3, the undersigned hereby agrees that from the date hereof and until 90 days after the public offering date set forth on the final prospectus supplement used to sell the Common Stock (the “Public Offering Date”) pursuant to the Underwriting Agreement (such 90 day period being referred to herein as the “Lock-Up Period”), to which you are or expect to become parties, the undersigned will not (and will cause any spouse or immediate family member of the spouse or the undersigned living in the undersigned’s household, any partnership, corporation or other entity within the undersigned’s control, and any trustee of any trust that holds Common Stock or other securities of the Company for the benefit of the undersigned or such spouse or family member (each such person or entity a “Controlled Party”) not to) offer, sell, contract to sell (including any short sale), pledge, hypothecate, establish an open “put equivalent position” within the meaning of Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended, grant any option, right or warrant for the sale of, purchase any option or contract to sell, sell any option or contract to purchase, or otherwise encumber, dispose of or transfer, or grant any rights with respect to, directly or indirectly, any shares of Common Stock or securities convertible into or exchangeable or exercisable for any shares of Common Stock, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such aforementioned transaction is to be settled by delivery of the Common Stock or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of Xxxxxx, Xxxxxxxx & Company, Incorporated (“Xxxxxx Xxxxxxxx”), which consent may be withheld in Xxxxxx Xxxxxxxx’ sole discretion; provided, however, that if (i) during the last 17 days of the initial Lock-Up Period, the Company releases earnings results or material news or a material event relating to the Company occurs or (ii) prior to the expiration of the initial Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the initial Lock-Up Period, then in each case the Lock-Up Period will be automatically extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable, unless Xxxxxx Xxxxxxxx waives, in writing, such extension.

The undersigned hereby acknowledges and agrees that written notice of any extension of the Lock-Up Period pursuant to the previous paragraph will be delivered by Xxxxxx Xxxxxxxx to the Company and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Agreement during the period from the date of this Agreement to and including the 34^th day following the expiration of the initial Lock-Up Period, it will give notice thereof to Xxxxxx Xxxxxxxx and will not consummate such transaction or take any such action unless it has received written confirmation from Xxxxxx Xxxxxxxx that the Lock-Up Period (as may have been extended pursuant to the previous paragraph) has expired.

The foregoing restrictions shall not apply to (i) bona fide gifts by the undersigned, provided that (a) each resulting transferee of the Company’s securities who is not a Controlled Party executes and delivers to Xxxxxx Xxxxxxxx an agreement satisfactory to Xxxxxx Xxxxxxxx certifying that such transferee is bound by the terms of this Agreement and has been in compliance with the terms hereof since the date first above written as if it had been an original party hereto and (b) to the extent any interest in the Company’s securities is retained by the undersigned (or such spouse or family member), such securities shall remain subject to the restrictions contained in this Agreement; (ii) the exercise of options to purchase Common Stock expiring during the Lock-Up Period (provided that, unless otherwise provided herein, such shares of Common Stock received upon exercise shall also be subject to this Agreement) and the disposition to the Company of shares of Common Stock acquired upon the exercise of such stock options to the extent necessary to pay the exercise price and related withholding taxes; (iii) the disposition of shares of Common Stock to the extent necessary to pay withholding taxes due in connection with the vesting of restricted stock during the Lock-Up Period; (iv) the transfer of Common Stock or options to an ex-spouse pursuant to a domestic relations order; (v) a pledge of shares of Common Stock securing indebtedness of the undersigned that existed on the date hereof, provided, however, that such pledge is not related to additional advances on such indebtedness made on or after the date hereof; (vi) any Common Stock acquired by the undersigned in the open market on or after the Public Offering Date; and (vii) any transfer of Common Stock to a Controlled Party.

[NOTE: TO BE INCLUDED IN THE LOCKUP FOR MESSRS. CHIOINI AND XXXXX ONLY: In addition, beginning on March 1, 2012, the foregoing restrictions shall not apply to the sale or bona fide pledge of shares of Common Stock to the extent that the net proceeds of such sale or loan for which the securities are pledged do not to exceed $400,000 in the aggregate (excluding sales or transfers covered by the exceptions in the immediately preceding paragraph).]

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to (a) decline to make any transfer of shares of Common Stock if such transfer would constitute a violation or breach of this Agreement and (b) place legends and stop transfer instructions on any such shares of Common Stock owned or beneficially owned by the undersigned.

This Agreement is irrevocable and shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to choice of law rules. This Agreement shall lapse and become null and void (i) upon written notice from the Company to Xxxxxx Xxxxxxxx that the Company does not intend to proceed with the public offering or wishes to terminate the engagement of Xxxxxx Xxxxxxxx prior to the public offering or (ii) if the Public Offering Date shall not have occurred on or before February 29, 2012.


Very truly yours,
