EXHIBIT A

Terms and Conditions for Exchange of Securities

Each of Immunomedics, Inc. a Delaware corporation (the “Company”), and the undersigned (the “Investor”), for itself and on behalf of the beneficial owners listed on Exhibit B.1 to the Exchange Agreement for whom the Investor holds contractual and investment authority (together with the Investor, the “Exchanging Investors”), hereby confirms its agreement pursuant to that certain exchange agreement, dated as of the date hereof (the “Exchange Agreement”), to which these Terms and Conditions for Exchange of Securities (the “Terms and Conditions”) are attached as Exhibit A, as set forth in these Terms and Conditions and in the Exchange Agreement (together, this “Agreement”) relating to the exchange of certain Notes for Shares as set forth in this Agreement.  Capitalized terms used but not defined in the Terms and Conditions have the meanings set forth in the Exchange Agreement.

1.Exchange Consideration; Exchange.  On the basis of the representations, warranties and agreements herein contained and subject to the terms and conditions herein set forth, the Investor hereby agrees to exchange, and to cause the other Exchanging Investors to exchange $[         ] aggregate principal amount of the Notes (the “Exchanged Notes”) for [         ] Shares (the “Exchange Consideration”).

“Market Disruption Event” means (i) a failure by the primary U.S. national or regional securities exchange or market on which the Common Stock is listed or admitted to trading (the “Primary Exchange”) to open for trading during its regular trading session or (ii) the occurrence or existence on any Scheduled Trading Day (as defined in the Indenture) of any suspension or limitation imposed on trading on the Primary Exchange (by reason of movements in price exceeding limits permitted by the Primary Exchange or otherwise) in the Common Stock or in any options, contracts or future contracts relating to the Common Stock for more than a one half-hour period in the aggregate during regular trading hours of the Primary Exchange prior to 1:00 p.m., New York City time.

“Trading Day” is defined in the Indenture; provided that references to Market Disruption Event for purposes thereof shall be deemed to be references to “Market Disruption Event” as defined herein.

The Exchange shall occur in accordance with the Exchange Procedures; provided that each of the Company and the Investor acknowledges that the delivery of the Exchanged Notes for withdrawal through the Deposits and Withdrawal at Custodian (“DWAC”) program through the DTC or the delivery of the Shares to any Exchanging Investor may be delayed due to procedures and mechanics within the system of the DTC or The NASDAQ Global Market (“NASDAQ”) (including the procedures and mechanics regarding the listing of the Shares on NASDAQ) and that such a delay will not be a default under this Agreement so long as (i) the Investor and/or the Company, as the case may be, is using its reasonable best efforts to effect such delivery, and (ii) such delay is no longer than three business days; provided, further, that no delivery of Shares will be made until such Exchanged Notes have been properly submitted for withdrawal through the DWAC program in accordance with this Agreement, and no accrued interest will be payable by reason of any delay in making such delivery.

The cancellation of the Exchanged Notes shall be effected through the DWAC program in accordance with the customary procedures of the Trustee.

For the avoidance of doubt, as of the Trading Day prior to the Closing (as defined below), the aggregate principal amount of Exchanged Notes shall be terminated and cancelled in full and the Exchanging Investors shall have no rights thereunder, except the right to receive the Shares on the Closing Date.

2.The Closing. The closing of the Exchange will take place at a closing (the “Closing”), which shall take place at the offices of DLA Piper LLP (US) at 12:00 p.m., New York City time, on October 5, 2018, or the next Trading Day thereafter (the “Closing Date”), or at such other time and place as the Company and the Investor may mutually agree.

(l)Neither the Company nor any of its subsidiaries is (i) in violation of its charter or by-laws or similar organizational documents; (ii) in default, and no event has occurred that, with notice or lapse of time or both, would constitute such a default, in the due performance or observance of any term, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject; or (iii) in violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory authority (including, without limitation,

and the Shares, and the Company does not, and Cowen and Company, LLC (the “Placement Agent”) does not, take any responsibility for, and neither the Company nor the Placement Agent can provide any assurance as to the reliability of, any other information that others may provide to the Investor or any Exchanging Investor.

(h)The Investor and each Exchanging Investor has such knowledge, skill and experience in business, financial and investment matters so that it is capable of evaluating the merits and risks with respect to the Exchange and an investment in the Shares. With the assistance of each Exchanging Investor’s own professional advisors, to the extent that the Exchanging Investor has deemed appropriate, such Exchanging Investor has made its own legal, tax, accounting and financial evaluation of the merits and risks of an investment in the Shares and the consequences of the Exchange and this Agreement and the Exchanging Investor has made its own independent decision that the investment in the Shares is suitable and appropriate for the Exchanging Investor.  Each Exchanging Investor has considered the suitability of the Shares as an investment in light of such Exchanging Investor’s circumstances and financial condition and is able to bear the risks associated with an investment in the Shares.

(i)The Investor confirms that it and each Exchanging Investor is not relying on any communication (written or oral) of the Company, the Placement Agent or any of their respective affiliates or representatives as investment advice or as a recommendation to purchase the Shares in the Exchange. It is understood that information provided by the Company, the Placement Agent or any of their respective affiliates and representatives shall not be considered investment advice or a recommendation to conduct the Exchange, and that none of the Company, the Placement Agent or any of their respective affiliates or representatives is acting or has acted as an advisor to the Investor or any Exchanging Investor in deciding to invest in the Shares.

(j)The Investor confirms that the Company has not (i) given any guarantee, representation or warranty as to the potential success, return, effect or benefit (either legal, regulatory, tax, financial, accounting or otherwise) of an investment in the Shares or (ii) made any representation or warranty to the Investor or any Exchanging Investor regarding the legality of an investment in the Shares under applicable legal investment or similar laws or regulations. In deciding to participate in the Exchange, the Investor is not relying on the advice or recommendations of the Company and the Investor has made its own independent decision that the investment in the Shares is suitable and appropriate for the Investor.

(k)The Investor and each Exchanging Investor is familiar with the business and financial condition and operations of the Company and the Investor and each Exchanging Investor has had the opportunity to conduct its own investigation of the Company and the Shares. The Investor and each Exchanging Investor has had access to the SEC filings of the Company and such other information concerning the Company and the Shares as it deems necessary to enable it to make an informed investment decision concerning the Exchange.  The Investor and each Exchanging Investor has been offered the opportunity to ask such questions of the Company and its representatives concerning the Company, its business, operations, performance, financial condition and prospects and the terms and conditions of the Exchange and has received answers thereto, as it deems necessary to enable it to make an informed investment decision concerning the Exchange.

(l)The Investor acknowledges and understands that at the time of the Closing, the Company may be in possession of material non-public information not known to the Investor or any Exchanging Investor that may impact the value of the Notes, including the Exchanged Notes, and the Shares (“Information”) that the Company is unable to disclose to the Investor or any Exchanging Investor. The Investor and each Exchanging Investor understands, based on its experience, the disadvantage to which the Investor and each Exchanging Investor is subject due to the disparity of information between the Company, on the one hand, and the Investor and each Exchanging Investor, on the other hand. Notwithstanding this, the Investor and each Exchanging Investor has deemed it appropriate to participate in the Exchange.  The Investor agrees that the Company and its directors, officers, employees, agents, stockholders and affiliates shall have no liability to the Investor or any Exchanging Investor or its beneficiaries whatsoever due to or in connection with the Company’s use or non-disclosure of the Information or otherwise as a result of the Exchange contemplated hereby, and the Investor hereby irrevocably waives any claim that it or any Exchanging Investor might have based on the failure of the Company to disclose the Information.

(m)The Investor and each Exchanging Investor understands that no federal, state, local or foreign agency has passed upon the merits or risks of an investment in the Shares or made any finding or determination concerning the fairness or advisability of this investment.

(n)Each Exchanging Investor is an “accredited investor” as defined in Rule 501(a) under the Securities Act and it and any account (including for purposes of this Section 4(n), the Accounts) for which it is acting (for which it has sole investment discretion) is a “qualified institutional buyer” as defined in Rule 144A under the Securities Act. The Investor agrees to furnish any additional information reasonably requested by the Company or any of its affiliates to assure compliance with applicable U.S. federal and state securities laws in connection with the Exchange.

(o)The Investor and each Exchanging Investor (i) has held its respective Exchanged Notes for at least six (6) months and (ii) is not, and has not been during the consecutive three month period preceding the date hereof and as of the Closing, will not be, a director, officer or “affiliate” within the meaning of Rule 144 under the Securities Act (an “Affiliate”) of the Company. To the Investor’s best knowledge, no Exchanging Investor acquired any of the Notes, directly or indirectly, from an Affiliate of the Company. Each Exchanging Investor and its Affiliates collectively beneficially own and will beneficially own as of the Closing Date (i) less than 10% of the outstanding Shares and (ii) less than 10% of the aggregate number of votes that may be cast by holders of those outstanding securities of the Company that entitle the holders thereof to vote generally on all matters submitted to the Company’s stockholders for a vote (the “Voting Power”). No Exchanging Investor is a subsidiary, affiliate or, to the Investor’s knowledge, otherwise closely-related to any director or officer of the Company or beneficial owner of 10% or more of the outstanding Shares or Voting Power (each such director, officer or beneficial owner, a “Related Party”). To the Investor’s knowledge, no Related Party beneficially owns 10% or more of the outstanding voting equity, or votes entitled to be cast by the outstanding voting equity, of any Exchanging Investor.

(p)Neither the Investor nor any Exchanging Investor is directly, or indirectly through one or more intermediaries, controlling or controlled by, or under direct or indirect common control with, the Company.

(q)Each Exchanging Investor is acquiring the Shares solely for its own beneficial account (or for any account (including for purposes of this Section 4(q), the Accounts) for which it has sole investment discretion), for investment purposes, and not with a view to, or for resale in connection with, any distribution of the Shares. The Investor and each Exchanging Investor understands that the Shares have not been registered under the Securities Act or any state securities laws and are being issued without registration under the Securities Act by reason of specific exemption(s) under the provisions thereof which depend in part upon the investment intent of the Exchanging Investors and the accuracy of the other representations and warranties made by the Investor in this Agreement. The Investor and the Exchanging Investors understand that the Company is relying upon the representations, warranties and agreements contained in this Agreement (and any supplemental information provided to the Company by the Investor or the Exchanging Investors) for the purpose of determining whether this transaction meets the requirements for such exemption(s).

(r)The Investor acknowledges that the terms of the Exchange have been mutually negotiated between the Investor and the Company.  The Investor was given a meaningful opportunity to negotiate the terms of the Exchange.

(s)The Investor acknowledges that it and each Exchanging Investor had a sufficient amount of time to consider whether to participate in the Exchange and that neither the Company nor the Placement Agent has placed any pressure on the Investor or any Exchanging Investor to respond to the opportunity to participate in the Exchange.  The Investor acknowledges that neither it nor any Exchanging Investor become aware of the Exchange through any form of general solicitation or advertising within the meaning of Rule 502 under the Securities Act or otherwise through a “public offering” under Section 4(a)(2) of the Securities Act.

(t)The operations of the Investor and each Exchanging Investor have been conducted in material compliance with the applicable rules and regulations administered or conducted by the U.S. Department of Treasury Office of Foreign Assets Control (“OFAC”), the applicable rules and regulations of the Foreign Corrupt Practices Act (“FCPA”) and the applicable Anti-Money Laundering (“AML”) rules in the Bank Secrecy Act. The Investor has performed due diligence necessary to reasonably determine that the Exchanging Investors are not named on the lists of denied parties or blocked persons administered by OFAC, resident in or organized under the laws of a country that is the subject of comprehensive economic sanctions and embargoes administered or conducted by OFAC (“Sanctions”), are not otherwise the subject of Sanctions and have not been found to be in violation or under suspicion of violating OFAC, FCPA or AML rules and regulations.

(u)The Investor acknowledges it and each Exchanging Investor understands that the Company intends to pay the Placement Agent a fee in respect of the Exchange.

(v)The Investor will, upon request, execute and deliver, for itself and on behalf of any Exchanging Investor, any additional documents deemed by the Company and the Trustee or the transfer agent to be reasonably necessary to complete the transactions contemplated by this Agreement.

(w)The Investor understands that, unless the Investor notifies the Company in writing to the contrary before the Closing, each of the Investor’s representations and warranties contained in this Agreement will be deemed to have been reaffirmed and confirmed as of the Closing.

(x)No later than one (1) business day after the date hereof, the Investor agrees to deliver to the Company settlement instructions substantially in the form of Exhibit B.1 attached to the Exchange Agreement for each of the Exchanging Investors.

(y)The Investor acknowledges and agrees that it and each Exchanging Investor has not transacted, and will not transact, in any securities of the Company, including, but not limited to, any hedging transactions, from the time the Investor was first contacted by the Company or the Placement Agent with respect to the transactions contemplated this Agreement until after the confidential information (as described in the confirmatory wall-crossing email received by the Investor from the Placement Agent) is made public.

(z)The Investor acknowledges that the Company may issue appropriate stop-transfer instructions to its transfer agent, if any, and may make appropriate notations to the same effect in its books and records to ensure compliance with the provisions of this Section 4.

(aa)The Investor understands that the Company, the Placement Agent and others will rely upon the truth and accuracy of the foregoing representations, warranties and covenants and agrees that if any of the representations and warranties deemed to have been made by it by its participation in the transactions contemplated by this Agreement and acquisition of the Shares are no longer accurate, the Investor shall promptly notify the Company and the Placement Agent. The Investor understands that, unless the Investor notifies the Company in writing to the contrary before the Closing, each of the Investor’s representations and warranties contained in this Agreement will be deemed to have been reaffirmed and confirmed as of the Closing.

(bb)The Investor acknowledges and agrees that the Placement Agent has not acted as a financial advisor or fiduciary to the Investor or any Exchanging Investor and that the Placement Agent and its respective directors, officers, employees, representatives and controlling persons have no responsibility for making, and have not made, any independent investigation of the information contained herein or in the Company’s SEC filings and make no representation or warranty to the Investor or any Exchanging Investor, express or implied, with respect to the Company, the Notes or the Shares or the accuracy, completeness or adequacy of the information provided to the Investor or any Exchanging Investor or any other publicly available information, nor shall any of the foregoing persons be liable for any loss or damages of any kind resulting from the use of the information contained therein or otherwise supplied to the Investor or any Exchanging Investor.

EXHIBIT C

Under U.S. federal income tax law, a holder who exchanges Notes for Shares generally must provide such holder’s correct TIN on IRS Form W-9 below or otherwise establish a basis for exemption from backup withholding. A TIN is generally an individual holder’s social security number or a holder’s employer identification number. If the correct TIN is not provided, the holder may be subject to a $50 penalty imposed by the IRS under Section 6723 of the Internal Revenue Code of 1986, as amended. In addition, certain payments made to holders may be subject to U.S. backup withholding (currently set at 28% of the payment). If a holder is required to provide a TIN but does not have a TIN, the holder should consult its tax advisor regarding how to obtain a TIN. Certain holders are not subject to these backup withholding and reporting requirements. A Non-U.S. holder must establish its status as an exempt recipient from backup withholding and can do so by submitting a properly completed IRS Form W-8 (available from the Company), signed, under penalties of perjury, attesting to such holder’s exempt foreign status.  U.S. backup withholding is not an additional tax. Rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is timely furnished to the IRS.  Holders are urged to consult their tax advisors regarding how to complete the appropriate forms and to determine whether they are exempt from backup withholding or other withholding taxes.
