Dear Sirs:

     1. INTRODUCTION. ThermoGenesis Corp., a Delaware corporation (the “Company”), proposes to issue and sell to the purchasers, pursuant to the terms and conditions of this Placement Agent Agreement (this “Agreement”) and the Subscription Agreements in the form of Exhibit A attached hereto (the “Subscription Agreements”) entered into with the purchasers identified therein (each a “Purchaser” and collectively, the “Purchasers”), up to an aggregate of 2,250,000 units (the “Units”) with each Unit consisting of (i) one share of common stock, $0.001 par value per share (the “Common Stock”), of the Company (each, a “Share,” and, collectively, the “Shares”), and (ii) one warrant to purchase one-half of one share of Common Stock (each, a “Warrant” and, collectively, the “Warrants”). The terms and conditions of the Warrants are set forth in the form of Exhibit B attached to the Subscription Agreements. The Units will not be issued or certificated. The Shares and Warrants are immediately separable and will be issued separately. The Company hereby confirms its agreement with Houlihan Lokey Capital, Inc. (the “Agent”) to act as the placement agent in accordance with the terms and conditions hereof.

     2. AGREEMENT TO ACT AS PLACEMENT AGENT; PLACEMENT OF UNITS. On the basis of the representations, warranties and agreements of the Company herein contained, and subject to all the terms and conditions of this Agreement:

          2.1 The Company has authorized and hereby acknowledges that the Agent has acted as its exclusive agent to solicit offers for the purchase of all or part of the Units from the Company in connection with the proposed offering of the Units (the “Offering”). Until the Closing Date (as defined in Section 4 hereof), the Company shall not, without the prior written consent of the Agent, solicit or accept offers to purchase Units otherwise than through the Agent. The Company acknowledges and agrees that the Agent may utilize the expertise of its affiliates and partners in connection with the Agent’s placement agent activities.

          2.2 The Company hereby acknowledges that the Agent, as agent of the Company, used its commercially reasonable efforts to solicit offers to purchase the Units from the Company on the terms and subject to the conditions set forth in the Prospectus (as defined below). The Agent shall use commercially reasonable efforts to assist the Company in obtaining performance by each Purchaser whose offer to purchase Units was solicited by the Agent and accepted by the Company, including the prompt execution by each Purchaser of a Subscription

Agreement to purchase Units, but the Agent shall not, except as otherwise provided in this Agreement, be obligated to disclose the identity of any potential purchaser or have any liability to the Company in the event any such purchase is not consummated for any reason. Under no circumstances will the Agent be obligated to underwrite or purchase any Units for its own account and the Company acknowledges and agrees that, in soliciting purchases of Units, the Agent has acted, and is acting, solely as the Company’s agent, and not as a principal.

          2.3 Subject to the provisions of this Section 2, offers for the purchase of Units were and shall be solicited by the Agent as agent for the Company at such times and in such amounts as the Agent deems advisable. The Agent shall communicate to the Company, orally or in writing, each reasonable offer to purchase Units received by it as agent of the Company. The Company shall have the sole right to accept offers to purchase the Units and may reject any such offer, in whole or in part. The Agent shall have the right, in its discretion reasonably exercised, without notice to the Company, to reject any offer to purchase Units received by it, in whole or in part, and any such rejection shall not be deemed a breach of this Agreement.

          2.4 The Units are being sold to the Purchasers at a price of $2.00 per Unit. The purchases of the Units by the Purchasers shall be evidenced by the execution of Subscription Agreements by each of the Purchasers and the Company.

          2.5 As compensation for services rendered, (i) on the Closing Date (as defined in Section 4 hereof), the Company shall pay to the Agent by wire transfer of immediately available funds to an account or accounts designated by the Agent, an aggregate amount equal to 8.0% of the gross proceeds received by the Company from the sale of the Units on such Closing Date (the “Share Placement Fee”), and (ii) on each date of delivery of Warrant Shares in respect of the Warrant, the Company shall pay to the Agent by wire transfer of immediately available funds to an account or accounts designated by the Agent, an aggregate amount equal to 8.0% of the gross proceeds received by the Company (together with the Share Placement Fee, the “Placement Fee”) from the exercise of the Warrants on such date(s) of delivery.

          2.6 No Units which the Company has agreed to sell pursuant to this Agreement and the Subscription Agreements shall be deemed to have been purchased and paid for, or sold by the Company, until such Units shall have been delivered to the Purchaser thereof against payment by such Purchaser. If the Company shall default in its obligations to deliver Units to a Purchaser whose offer it has accepted, the Company shall indemnify and hold the Agent harmless against any loss, claim, damage or expense arising from or as a result of such default by the Company in accordance with the procedures set forth in Section 8(c) herein.

     3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents and warrants to, and agrees with, the Agent and the Purchasers that:

          (z) The Company and each of its subsidiaries have good and marketable title in fee simple to, or have valid rights to lease or otherwise use, all items of real or personal property that are material to the business of the Company and its subsidiaries taken as a whole, in each case free and clear of all liens, encumbrances, security interests, claims and defects that do not, singularly or in the aggregate, materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company or any of its subsidiaries; and all of the leases and subleases material to the business of the Company and its subsidiaries, considered as one enterprise, and under which the Company or any of its subsidiaries holds properties described in the General Disclosure Package and the Prospectus, are in full force and effect, and neither the Company nor any subsidiary has received any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company or any subsidiary under any of the leases or subleases mentioned above, or negatively affecting or questioning the rights of the Company or such subsidiary to the continued possession of the leased or subleased premises under any such lease or sublease.

          (aa) No labor disturbance by the employees of the Company or any of its subsidiaries that would reasonably be expected to have a Material Adverse Effect either exists or, to the best of the Company’s knowledge, is imminent. Except as set forth in the General Disclosure Package, the Company is not aware that any key employee or significant group of employees of the Company or any subsidiary voluntarily plans to terminate employment with the Company or any such subsidiary.

          (bb) No “prohibited transaction” (as defined in Section 406 of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”), or Section 4975 of the Internal Revenue Code of 1986, as amended from time to time (the “Code”)) or “accumulated funding deficiency” (as defined in Section 302 of ERISA) or any of the events set forth in Section 4043(b) of ERISA (other than events with respect to which the thirty (30)-day notice requirement under Section 4043 of ERISA has been waived) has occurred or could reasonably be expected to occur with respect to any employee benefit plan of the Company or any of its subsidiaries which would, singularly or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each employee benefit plan of the Company or any of its subsidiaries is in compliance in all material respects with applicable law, including ERISA and the Code. The Company and its subsidiaries have not incurred and would not reasonably be expected to incur liability under Title IV of ERISA with respect to the termination of, or withdrawal from, any pension plan (as defined in ERISA). Each pension plan for which the Company or any of its subsidiaries would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects, and nothing has occurred, whether by action or by failure to act, which could, singularly or in the aggregate, reasonably be expected to cause the loss of such qualification.

          (cc) The Company and its subsidiaries are in compliance with all foreign, federal, state and local statute, law (including the common law), ordinance, rule, regulation, order, judgment, decree or Governmental Permit, relating to the use, treatment, storage and disposal of hazardous or toxic substances, materials or wastes and the protection of health and safety or the environment which are applicable to their businesses (“Environmental Laws”), except where the failure to comply would not, singly or in the aggregate, reasonably be expected to have a Material Adverse Effect. There has been no storage, generation, transportation, handling, treatment, disposal, discharge, emission, or other release of any kind of hazardous or toxic substances, materials or wastes by, due to, or caused by the Company or any of its subsidiaries (or, to the best of the Company’s knowledge, any other entity for whose acts or omissions the Company or any of its subsidiaries is or may otherwise be liable) upon any of the property now or previously owned or leased by the Company or any of its subsidiaries, or upon any other property, in violation of, or which would give rise to any liability under, any Environmental Law, except for any violation or liability which would not reasonably be expected to have, singly or in the aggregate with all such violations and liabilities, a Material Adverse Effect; and there has been no disposal, discharge, emission or other release of any kind onto such property or into the environment surrounding such property of any hazardous or toxic substances, materials or wastes with respect to which the Company has knowledge, except for any such disposal, discharge, emission, or other release of any kind which would not reasonably be expected to have, singly or in the aggregate with all such discharges and other releases, a Material Adverse Effect.

The Company and its subsidiaries each has not engaged in any transaction which is a corporate tax shelter or which could reasonably be characterized as such by the Internal Revenue Service or any other taxing authority. The accruals and reserves on the books and records of the Company and its subsidiaries in respect of tax liabilities for any taxable period not yet finally determined are adequate to meet any assessments and related liabilities for any such period, and since June 30, 2010, none of the Company or any of its subsidiaries has incurred any liability for taxes other than in the ordinary course.

          (ee) The Company and each of its subsidiaries carry, or are covered by, insurance provided by recognized, financially sound and reputable institutions with policies in such amounts and covering such risks as is adequate for the conduct of their respective businesses and the value of their respective properties and as is customary for companies engaged in similar businesses in similar industries. The Company has no reason to believe that it or any subsidiary will not be able to (i) renew its existing insurance coverage as and when such policies expire or (ii) obtain comparable coverage from similar institutions as may be necessary

or appropriate to conduct its business as now conducted and at a cost that would not reasonably be expected to have a Material Adverse Effect. The Company has not been denied any insurance coverage that it has sought or for which it has applied.

          (ff) The Company and each of its subsidiaries maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15 of the General Rules and Regulations under the Exchange Act (the “Exchange Act Rules”)) that complies with the requirements of the Exchange Act and has been designed to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Since the end of the Company’s most recent audited fiscal year, there as been (A) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (B) 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. The Company maintains disclosure controls and procedures (as such is defined in Rule 13a-15 of the Exchange Act Rules) that comply with the requirements of the Exchange Act; such disclosure controls and procedures have been designed to ensure that information required to be disclosed by the Company and its subsidiaries is accumulated and communicated to the Company’s management, including the Company’s principal executive officer and principal financial officer by others within those entities, such disclosure controls and procedures are effective in all material respects to perform the functions for which they were established.

          (gg) The minute books of the Company and each of its subsidiaries that would be a “significant subsidiary” within the meaning of Rule 1-02(w) of Regulation S-X under the Exchange Act have been made available to the Agent and counsel for the Agent, and such books (i) contain a complete summary of all meetings and actions of the board of directors (including each board committee) and stockholders of the Company, and each of such subsidiaries since the time of its respective incorporation or organization through the date of the latest meeting and action, and (ii) accurately in all material respects reflect all transactions referred to in such minutes or written consents.

          (hh) There is no franchise, lease, contract, agreement or document required by the Securities Act or by the Rules and Regulations to be described in the General Disclosure Package and in the Prospectus or a document incorporated by reference therein or to be filed as an exhibit to the Registration Statement or a document incorporated by reference therein which is not described or filed therein as required; and all descriptions of any such franchises, leases, contracts, agreements or documents contained in the Registration Statement or the General Disclosure Package or in any document incorporated by reference therein are accurate and complete descriptions of such documents. Other than as described in the General Disclosure Package, no such franchise, lease, contract or agreement has been suspended or terminated for convenience or default by the Company or any of its subsidiaries or any of the other parties thereto, and none of the Company or any of its subsidiaries has received notice nor does the Company have any other knowledge of any such pending or threatened suspension or

termination, except for such pending or threatened suspensions or terminations that would not reasonably be expected to, singularly or in the aggregate, have a Material Adverse Effect.

          (ii) No relationship, direct or indirect, exists between or among the Company and any of its subsidiaries, on the one hand, and the directors, officers, stockholders, customers or suppliers of the Company or any of its subsidiaries or any of their affiliates, on the other hand, that is required to be described in the General Disclosure Package and the Prospectus or a document incorporated by reference therein and that is not so described.

          (jj) No person or entity has the right to require registration of shares of Common Stock or other securities of the Company or any of its subsidiaries because of the filing or effectiveness of the Registration Statement or otherwise, except for persons and entities who have expressly waived such right in writing or who have been given timely and proper written notice and have failed to exercise such right within the time or times required under the terms and conditions of such right. Except as described in the General Disclosure Package, there are no persons with registration rights or similar rights to have any securities registered for sale under the Registration Statement or to include such securities in the Offering.

          (kk) None of the Company or any of its subsidiaries own any “margin securities” as that term is defined in Regulation U of the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”), and none of the proceeds of the sale of the Units will be used, directly or indirectly, for the purpose of purchasing or carrying any margin security, for the purpose of reducing or retiring any indebtedness which was originally incurred to purchase or carry any margin security or for any other purpose which might cause any of the Units to be considered a “purpose credit” within the meanings of Regulation T, U or X of the Federal Reserve Board.

          (ll) Other than this Agreement and that certain letter agreement, dated October 26, 2010, by and between the Company and the Agent, none of the Company or any of its subsidiaries is a party to any contract, agreement or understanding with any person that would give rise to a valid claim against the Company, the Agent for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Units or any transaction contemplated by this Agreement, the Registration Statement, the General Disclosure Package or the Prospectus.

          (mm) No forward-looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act) contained in the General Disclosure Package or the Prospectus has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith.

          (nn) The Company is subject to and in compliance in all material respects with the reporting requirements of Section 13 or Section 15(d) of the Exchange Act.

          (rr) There are no transactions, arrangements or other relationships between and/or among the Company, any of its affiliates (as such term is defined in Rule 405 of the Securities Act) and any unconsolidated entity, including, but not limited to, any structured finance, special purpose or limited purpose entity that could reasonably be expected to materially affect the Company’s or any of its subsidiaries’ liquidity or the availability of or requirements for their capital resources, which transaction, arrangement or other relationship is required to be described in the General Disclosure Package and the Prospectus or any document incorporated by reference therein that has not been described as required.

     5. FURTHER AGREEMENTS OF THE COMPANY. The Company agrees with the Agent and the Purchasers:

          (a) To prepare the Rule 462(b) Registration Statement, if necessary, in a form approved by the Agent and file such Rule 462(b) Registration Statement with the Commission on the date hereof; to prepare the Prospectus in a form approved by the Agent containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on rules 430A, 430B or 430C of the Rules and Regulations and to file such Prospectus pursuant to Rule 424(b) of the Rules and Regulations not later than the second business (2nd) day following the execution and delivery of this Agreement or, if applicable, such earlier time as may be required by Rule 430A of the Rules and Regulations; to notify the Agent promptly of the Company’s intention to file or prepare any supplement or amendment to any Registration Statement or to the Prospectus and to make no amendment or supplement to the Registration Statement, the General Disclosure Package or to the Prospectus to which the Agent shall reasonably object by notice to the Company after a reasonable period to review; to advise the Agent, promptly after it receives notice thereof, of the time when any amendment to any Registration Statement has been filed or becomes effective or any supplement to the General Disclosure Package or the Prospectus or any amended Prospectus has been filed and to furnish the Agent with copies thereof; to file within the time periods prescribed by the Exchange Act, including any extension thereof, all material required to be filed by the Company with the Commission pursuant to Rules 433(d) or 163(b)(2) of the Rules and Regulations, as the case may be; to file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and for so long as the delivery of a prospectus (or in lieu thereof, the notice referred to in Rule 173(a) of the Rules and Regulations) is required in connection with the offering or sale of the Units; to advise the Agent, promptly after it receives notice thereof, of the issuance by the Commission of any stop order or of any order preventing or suspending the use of any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus, of the suspension of the qualification of the Units for offering or sale in any jurisdiction, of the initiation or threatening of any proceeding for any such purpose, or of any request by the Commission for the amending or supplementing of the Registration Statement, the General Disclosure Package or the Prospectus or for additional information; and, in the event of the issuance of any stop order or of any order preventing or suspending the use of any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus or suspending any such qualification, and promptly to use its best efforts to obtain the withdrawal of such order.

          (b) The Company represents and agrees that, unless it obtains the prior consent of the Agent, it has not made and will not, make any offer relating to the Units that would constitute a “free writing prospectus” as defined in Rule 405 of the Rules and Regulations (each, a “Permitted Free Writing Prospectus”); provided that the prior written consent of the Agent shall be deemed to have been given in respect of the General Use Free Writing Prospectus, if any, included in Exhibit A hereto. The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, comply with the requirements of Rules 164 and 433 of the Rules and Regulations applicable to any Issuer Free Writing Prospectus, including the requirements relating to timely filing with the Commission, legending and record keeping and will not take any action that would result in the Agent or the Company being required to file with the Commission pursuant

to Rule 433(d) of the Rules and Regulations a free writing prospectus prepared by or on behalf of the Agent that the Agent otherwise would not have been required to file thereunder.

          (c) If at any time when a Prospectus relating to the Units is required to be delivered under the Securities Act, any event occurs or condition exists as a result of which the Prospectus, as then amended or supplemented, would include 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, or the Registration Statement, as then amended or supplemented, would include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading, or if for any other reason it is necessary at any time to amend or supplement any Registration Statement or the Prospectus or to file under the Exchange Act any document incorporated by reference in the Prospectus to comply with the Securities Act or the Exchange Act, the Company will promptly notify the Agent, and upon the Agent’s request, the Company will promptly prepare and file with the Commission, at the Company’s expense, an amendment to the Registration Statement or an amendment or supplement to the Prospectus or make an appropriate filing under Section 13 or 14 of the Exchange Act that corrects such statement or omission or effects such compliance and will deliver to the Agent, without charge, such number of copies thereof as the Agent may reasonably request. The Company consents to the use of the Prospectus or any amendment or supplement thereto by the Agent.

          (d) If the General Disclosure Package is being used to solicit offers to buy the Units at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur as a result of which, in the judgment of the Company or in the opinion of the Agent, it becomes necessary to amend or supplement the General Disclosure Package in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or to make the statements therein not conflict with the information contained or incorporated by reference in the Registration Statement then on file and not superseded or modified, or if it is necessary at any time to amend or supplement the General Disclosure Package to comply with any law, the Company promptly will either (i) prepare, file with the Commission (if required) and furnish to the Agent and any dealers an appropriate amendment or supplement to the General Disclosure Package or (ii) prepare and file with the Commission an appropriate filing under the Exchange Act which shall be incorporated by reference in the General Disclosure Package so that the General Disclosure Package as so amended or supplemented will not, in the light of the circumstances under which they were made, be misleading or conflict with the Registration Statement then on file, or so that the General Disclosure Package will comply with law.

          (e) If at any time following issuance of an Issuer Free Writing Prospectus in connection with the Offering there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or will conflict with the information contained in the Registration Statement, Pricing Prospectus or Prospectus, including any document incorporated by reference therein and any prospectus supplement deemed to be a part thereof and not superseded or modified or included or would include an untrue statement of a material fact or omitted or would omit to state a 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 Company has promptly notified or will promptly notify the Agent so that any use of the Issuer Free Writing Prospectus may cease until it is amended or

supplemented and has promptly amended or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus in reliance upon, and in conformity with, written information furnished to the Company through the Agent by or on behalf of the Agent specifically for inclusion therein, which information the parties hereto agree is limited to the Agent’s Information (as defined in Section 17).

          (h) As soon as practicable, but in any event not later than 45 days after the end of the 12-month period beginning at the end of the fiscal quarter of the Company during which the most recent effective date of the Registration Statement occurs (or 90 days after the end of such 12-month period if such 12-month period coincides with the Company’s fiscal year), the Company will make generally available to its security holders and to the Agent an earning statement (as defined in Rule 158(c) of the Securities Act) of the Company and its subsidiaries (which need not be audited), covering such 12-month period which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

          (i) The Company will promptly take from time to time such actions as the Agent may reasonably request to qualify the Units for offering and sale under the securities or Blue Sky laws of such jurisdictions (domestic or foreign) as the Agent may designate and to continue such qualifications in effect for so long as required for the distribution of the Securities; provided that the Company and its subsidiaries shall not be obligated to qualify as foreign corporations in any jurisdiction in which they are not so qualified or to file a general consent to service of process in any jurisdiction.

          (k) That the Company will not, for a period of ninety (90) days from the date of this Agreement, (the “Lock-Up Period”) without the prior written consent of the Agent, directly or indirectly offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, other than (i) the Company’s sale of the Units hereunder, (ii) the issuance of restricted Common Stock or options to acquire Common Stock pursuant to the Company’s employee benefit plans, qualified stock option plans or other employee compensation plans as such plans are in existence on the date hereof and described in the Prospectus, and (iii) the issuance of Common Stock pursuant to the valid exercises of options, warrants or rights outstanding on the date hereof.

     8. INDEMNIFICATION AND CONTRIBUTION.

          (a) The Company shall indemnify and hold harmless the Agent, each of its affiliates and each of its and their respective directors, officers, members, employees, representatives and agents, and each person, if any, who controls any Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively the “Agent Indemnified Parties,” and each a “Agent Indemnified Party”) against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), joint or several, to which a Agent Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon (A) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto or document incorporated by reference therein, (B) the omission or alleged omission to state in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto or document incorporated by reference therein, a material fact required to be stated therein or necessary to make the statements therein in the light of (other than in the case of any Registration Statement) the circumstances under which they are made not misleading, or (C) any breach of the representations and warranties of the Company contained herein or the failure of the Company to perform its obligations hereunder or pursuant to any law, any act or failure to act, or any alleged act or failure to act, by the Agent in connection with, or relating in any manner to, the Units or the Offering, and which is included as part of or referred to in any loss, claim, damage, expense, liability, action, investigation or proceeding arising out of or based upon matters covered by subclause (A), (B) or (C) above of this Section 8(a) (provided that the Company shall not be liable in the case of any matter covered by this subclause (C) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, expense or liability resulted solely and directly from any such act, or failure to act, undertaken or omitted to be taken by the Agent through its gross negligence or willful misconduct), and shall reimburse each Agent Indemnified Party promptly upon demand for any legal fees or other expenses reasonably incurred by that Agent Indemnified Party in connection with investigating, or preparing to defend, or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding, as such fees and 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, expense or liability arises out of or is based upon an untrue statement or alleged untrue statement in, or omission or alleged omission from any Preliminary Prospectus, any Registration Statement or the Prospectus, or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus made in reliance upon and in conformity with written information furnished to the Company through the Agent by or on behalf of the Agent specifically for use therein, which information the parties hereto agree is limited to the Agent’s Information (as defined in Section 17). The indemnity agreement in this Section 8(a) is not exclusive and is and will be in addition to any liability, which the Company might otherwise have and shall not limit any rights or remedies which may otherwise be available at law or in equity to each Agent Indemnified Party.

          (b) The Agent shall indemnify and hold harmless the Company and its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively the “Company Indemnified Parties” and each a “Company Indemnified Party”) against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), joint or several, to which such Company Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein in the light of (other than in the case of any Registration Statement) the circumstances under which they are made not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company through the Agent by or on behalf of the Agent specifically for use therein, which information the parties hereto agree is limited to the Agent’s Information (as defined in Section 17), and shall reimburse the Company Indemnified Parties for any legal or other expenses reasonably incurred by such party in connection with investigating or preparing to defend or defending against or appearing as third party witness in connection with any such loss, claim, damage, liability, action, investigation or proceeding, as such fees and expenses are incurred. Notwithstanding the provisions of this Section 8(b), in no event shall any indemnity by the Agent under this Section 8(b) exceed the total compensation received by the Agent in accordance with Section 2.5. This indemnity agreement is not exclusive and will be in addition to any liability which the Agent might otherwise have and shall not limit any rights or remedies which may otherwise be available under this Agreement, at law or in equity to the Company Indemnified Parties.

          (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify such indemnifying party in writing of the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure; and, provided, further, that the failure to notify an indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense of such action with counsel reasonably satisfactory to the indemnified party (which counsel shall not, except with the written consent of the indemnified party, be counsel to the indemnifying party). After notice from the indemnifying party to the indemnified party of its election to assume the defense of such action, except as provided herein, the indemnifying party shall not be liable to the indemnified party under Section 8 for any legal or other expenses subsequently

incurred by the indemnified party in connection with the defense of such action other than reasonable costs of investigation; provided, however, that any indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense of such action but the fees and expenses of such counsel (other than reasonable costs of investigation) shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized in writing by the Company in the case of a claim for indemnification under Section 8(a) or Section 2.6 or the Agent in the case of a claim for indemnification under Section 8(b), (ii) such indemnified party shall have been advised by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party within a reasonable period of time after notice of the commencement of the action or the indemnifying party does not diligently defend the action after assumption of the defense, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of (or, in the case of a failure to diligently defend the action after assumption of the defense, to continue to defend) such action on behalf of such indemnified party and the indemnifying party shall be responsible for legal or other expenses subsequently incurred by such indemnified party in connection with the defense of such action; provided, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties (in addition to any local counsel), which firm shall be designated in writing by the Agent if the indemnified parties under this Section 8 consist of the Agent Indemnified Party or by the Company if the indemnified parties under this Section 8 consist of any Company Indemnified Parties. Subject to this Section 8(c), the amount payable by an indemnifying party under Section 8 shall include, but not be limited to, (x) reasonable legal fees and expenses of counsel to the indemnified party and any other expenses in investigating, or preparing to defend or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any action, investigation, proceeding or claim, and (y) all amounts paid in settlement of any of the foregoing. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of judgment with respect to any pending or threatened action or any claim whatsoever, in respect of which indemnification or contribution could be sought under this Section 8 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party in form and substance reasonably satisfactory to such 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. Subject to the provisions of the following sentence, no indemnifying party shall be liable for settlement of any pending or threatened action or any claim whatsoever that is effected without its written consent (which consent shall not be unreasonably withheld or delayed), but if settled with its written consent, if its consent has been unreasonably withheld or delayed or if there be a judgment for the plaintiff in any such matter, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, if at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for reasonable fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature

contemplated herein effected without its written consent if (i) such settlement is entered into more than forty-five (45) days after receipt by such indemnifying party of the request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

          (d) If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under Section 8(a) or Section 8(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid, payable or otherwise incurred by such indemnified party as a result of such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof), as incurred, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Agent on the other hand from the Offering, or (ii) if the allocation provided by clause (i) of this Section 8(d) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) of this Section 8(d) but also the relative fault of the Company on the one hand and the Agent on the other with respect to the statements, omissions, acts or failures to act which resulted in such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof) as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Agent on the other with respect to such offering 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 Placement Fee received by the Agent in connection with the Offering, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company on the one hand and the Agent on the other 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 Agent on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement, omission, act or failure to act; provided that the parties hereto agree that the written information furnished to the Company by the Agent by and on behalf of the Agent for use in any Preliminary Prospectus, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, consists solely of the Agent’s Information as defined in Section 17. The Company and the Agent agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage, expense, liability, action, investigation or proceeding referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing to defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding. Notwithstanding the provisions of this Section 8(d), the Agent shall not be required to contribute any amount in excess of the total compensation received by the Agent in accordance with Section 2.5 less the amount of any damages which the Agent has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement, omission or alleged omission, act or alleged act or failure to act or alleged failure to act. 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.

     9. TERMINATION. The obligations of the Agent and the Purchasers hereunder and under the Subscription Agreements may be terminated by the Agent, in its sole and absolute discretion, by notice given to the Company prior to delivery of and payment for the Units if, prior to that time, any of the events described in Section 7(i), Section 7(j) or Section 7(k) have occurred or if the Purchasers shall decline to purchase the Units for any reason permitted under this Agreement or the Subscription Agreements.

     10. REIMBURSEMENT OF PLACEMENT AGENT’S EXPENSES. Notwithstanding anything to the contrary in this Agreement, if (a) this Agreement shall have been terminated pursuant to Section 9, (b) the Company shall fail to tender the Units for delivery to the Purchasers for any reason not permitted under this Agreement, (c) the Purchasers shall decline to purchase the Units for any reason permitted under this Agreement or (d) the sale of the Units is not consummated because any condition to the obligations of the Purchasers or the Agent set forth herein is not satisfied or because of the refusal, inability or failure on the part of the Company to perform any agreement herein or to satisfy any condition or to comply with the provisions hereof, then in addition to the payment of amounts in accordance with Section 6, the Company shall reimburse the Agent for the reasonable out-of-pocket accountable fees, costs and expenses of the Agent’s counsel and for such other reasonable accountable out-of-pocket expenses as shall have been incurred by them in connection with this Agreement and the proposed purchase of the Units, and upon demand, the Company shall pay the full amount thereof to the Agent.

     11. ABSENCE OF FIDUCIARY RELATIONSHIP. The Company acknowledges and agrees that:

          (a) The Agent’s responsibility to the Company is solely contractual in nature, the Agent has been retained solely to act as a placement agent in connection with the Offering and no fiduciary, advisory or agency relationship between the Company, on the one hand, and the Agent, on the other hand, has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether the Agent has advised or is advising the Company on other matters;

          (b) the price of the Units set forth in this Agreement was established by the Company following discussions and arms-length negotiations with the Agent, and the Company is capable of evaluating and understanding, and understands and accepts, the terms, risks and conditions of the transactions contemplated by this Agreement;

          (c) it has been advised that the Agent and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Agent has no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

Re:

ThermoGenesis Corp. — Registered Offering of Common Stock

Dear Sirs:

     This Agreement is being delivered to you in connection with the proposed Placement Agent Agreement (the “Placement Agent Agreement”) among ThermoGenesis Corp., a Delaware corporation (the “Company”) and Houlihan Lokey Capital, Inc. (“Houlihan” or the “Representative”), relating to the proposed offering of shares of the common stock, par value $0.001 per share (the “Common Stock”), of the Company.

     In order to induce you to enter into the Placement Agent Agreement, and in light of the benefits that the offering of the Common Stock will confer upon the undersigned in his or her capacity as a security holder and/or an officer, director or employee of the Company, and for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with the Representative that, during the period beginning on and including the date of the Placement Agent Agreement through and including the date that is the 90th day after the date of the Placement Agent Agreement (the “Lock-Up Period”), the undersigned will not, without the prior written consent of Houlihan, directly or indirectly, (i) offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, or announce the intention to otherwise dispose of, any Common Stock (including, without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations promulgated under the Securities Act of 1933, as the same may be amended or supplemented from time to time (such shares, the “Beneficially Owned Shares”)) or securities convertible into or exercisable or exchangeable for Common Stock; (ii) enter into any swap, hedge or similar agreement or arrangement that transfers in whole or in part, the economic risk of ownership of the Beneficially Owned Shares or securities convertible into or exercisable or exchangeable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or (iii) engage in any short selling of the Common Stock or securities convertible into or exercisable or exchangeable for Common Stock. To the extent you are at such time providing research coverage to the Company and subject to the restrictions set forth in FINRA Rule 2711(f)(4), then if (i) the Company issues an earnings release or material news or a material event relating to the Company occurs during the last 17 days of the Lock-Up Period, or (ii) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then in each case the Lock-Up Period shall be extended and the restrictions imposed by this Agreement shall

continue to apply until the expiration of the 18-day period beginning on the date of the issuance of the earnings release or the occurrence of the material news or material event.

     The restrictions set forth in the immediately preceding paragraph shall not apply to any transfers made by the undersigned (i) as a bona fide gift to any member of the immediate family (as defined below) of the undersigned or to a trust the beneficiaries of which are exclusively the undersigned or members of the undersigned’s immediate family, (ii) by will or intestate succession upon the death of the undersigned, (iii) as a bona fide gift to a charity or educational institution or (iv) by disposition of Common Stock or Beneficially Owned Shares pursuant to any trading plan designed to meet the requirements of the safe harbor of Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, existing prior to the Lock-up Period or entered into in renewal or replacement of such an existing plan upon its expiration on substantially similar terms, provided, however, that in the case of any transfer described in clauses (i) and (ii) above, it shall be a condition to the transfer that (A) the transferee executes and delivers to Houlihan, not later than one business day prior to such transfer, a written agreement, in substantially the form of this agreement (it being understood that any references to “immediate family” in the agreement executed by such transferee shall expressly refer only to the immediate family of the undersigned and not to the immediate family of the transferee) and otherwise satisfactory in form and substance to Houlihan, and (B) if the undersigned is required to file a report under Section 16(a) of the Securities Exchange Act of 1934, as amended, reporting a reduction in beneficial ownership of Common Stock or Beneficially Owned Shares or any securities convertible into or exercisable or exchangeable for Common Stock or Beneficially Owned Shares during the Lock-Up Period (as the same may be extended as described above), the undersigned shall include a statement in such report to the effect that such transfer is being made as a gift or by will or intestate succession. For purposes of this paragraph, “immediate family” shall mean a spouse, child, grandchild or other lineal descendant (including by adoption), father, mother, father-in-law, mother-in-law, brother or sister of the undersigned; and “affiliate” shall have the meaning set forth in Rule 405 under the Securities Act of 1933, as amended.

     Any Common Stock or Beneficially Owned Shares acquired by the undersigned in the open market after the date of this Agreement will not be subject to the restrictions set forth in this agreement. After the date of this agreement, the undersigned may at any time enter into a written plan meeting the requirements of Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, relating to the sale of Common Stock or Beneficially Owned Shares, if then permitted by the Company, provided, however, that the shares subject to such plan shall be subject to the restrictions set forth in this agreement.

     In order to enable this covenant to be enforced, the undersigned hereby consents to the placing of legends or stop transfer instructions with the Company’s transfer agent with respect to any Common Stock or securities convertible into or exercisable or exchangeable for Common Stock.

     The undersigned further agrees that (i) it will not, during the Lock-Up Period (as the same may be extended as described above), make any demand or request for or exercise any right with respect to the registration under the Securities Act of 1933, as amended, of any Common Stock or other Beneficially Owned Shares or any securities convertible into or exercisable or exchangeable for Common Stock or other Beneficially Owned Shares, and (ii) the

Company may, with respect to any Common Stock or other Beneficially Owned Shares or any securities convertible into or exercisable or exchangeable for Common Stock or other Beneficially Owned Shares owned or held (of record or beneficially) by the undersigned, cause the transfer agent or other registrar to enter stop transfer instructions and implement stop transfer procedures with respect to such securities during the Lock-Up Period (as the same may be extended as described above).

     The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this agreement and that this agreement has been duly executed and delivered by the undersigned and is a valid and binding agreement of the undersigned. This agreement and all authority herein conferred are irrevocable and shall survive the death or incapacity of the undersigned and shall be binding upon the undersigned and upon the heirs, personal representatives, successors and assigns of the undersigned.

     The undersigned acknowledges and agrees that whether or not any offering of Common Stock actually occurs depends on a number of factors, including market conditions. It is understood and agreed that if (i) the Placement Agent Agreement is not executed by May 30, 2011, (ii) the Company notifies you in writing that it does not intend to proceed with the offering of Common Stock, (iii) the undersigned ceases to serve as an officer or director of the Company, or (iv) the Placement Agent Agreement shall be terminated (other than the provisions that survive termination thereof) prior to payment for and delivery of the securities to be sold pursuant thereto, the undersigned shall be released from his or her obligations under the provisions of this agreement.

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