in 1998 and 2003 (collectively, the “Amended Agreements”); and 
 WHEREAS, the parties entered into an Amended and Restated
Employment Agreement effective as of July 1, 2007 (the “Amended and Restated Agreement”), which amended and restated in their entirety the Amended Agreements; and 
 WHEREAS, the parties entered into an amended to the Amended and Restated Agreement on January 31, 2008 (the “2008 Amendment”); and








 WHEREAS, the parties reached agreement on the terms of this Agreement, to amend and restate the Amended

upon the terms and conditions set forth in this Agreement. 
 2. Term. Unless earlier terminated by either party pursuant to
Section 10, this Agreement will continue for a four (4) year period following July 1, 2007 (through June 30, 2011) (the “Initial Term”). This Agreement automatically shall renew for additional one (1) year periods

 3. Duties. 
 (a) Description. Throughout the Term of this Agreement, Dr. Goldenberg shall serve as Chief Scientific Officer and Chief
Medical Officer of Immunomedics and shall perform such duties in these roles, which are commensurate with Dr. Goldenberg’s expertise, experience, roles fulfilled within the Company, and professional standing and the needs of the Company
from time to time, as the Board of Directors of Immunomedics (the “Board”), in consultation with Dr. Goldenberg, may determine from time to time. The Board may assign specific duties to Dr. Goldenberg after a review of
Immunomedics’ needs. Dr. Goldenberg will report directly to the Chief Executive Officer, and will continue to be accountable directly to the Board throughout the Term of this Agreement. Immunomedics reserves the right, subject to
Section 10(f) below, to modify, but not diminish, the nature and scope of Dr. Goldenberg’s duties to meet the Company’s changing needs, provided that such duties and level of authority shall remain commensurate with
Dr. Goldenberg’s expertise, experience and professional standing. If elected to such positions, Dr. Goldenberg may serve as a member of the Board, and as an executive officer and director of any subsidiary or affiliate of or successor
to Immunomedics and, in the Board’s discretion, may be paid additional, reasonable compensation for such services. 
 (b)
Best Efforts. Throughout the Term of this Agreement, Dr. Goldenberg shall faithfully, industriously and to the best of his ability, experience and talents, perform all of the duties contemplated by this Agreement and in accordance with
his fiduciary duties as an officer and director of the Company. In the course of performing such duties, Dr. Goldenberg shall cooperate fully, to the best of his ability, with the Board and all officers, agents and employees of Immunomedics in
all matters connected with the business of Immunomedics. 
  

 3 








 (c) Extent of Duties. Dr. Goldenberg shall devote such time to Immunomedics
as is reasonably necessary to fulfill the duties contemplated by this Agreement. Notwithstanding any language to the contrary, Immunomedics acknowledges and authorizes Dr. Goldenberg to perform the following roles and to dedicate the time
necessary to perform such roles, the scope of which Immunomedics acknowledges and agrees does not materially interfere with his performance of duties directly for Immunomedics: 
 (i) To serve as a member of the Board of Trustees of and to be employed (including without limitation as the President and/or Chief
Executive Officer) by the Center for Molecular Medicine and Immunology (a/k/a Garden State Cancer Center) or any of its subsidiaries, affiliates, successors or any non-profit substitute entity (collectively the “Center”), provided, that
any such subsidiary, affiliate, successor or non-profit substitute entity agrees to undertake all of the obligations of the Center pursuant to any existing or future license, proprietary rights or other equivalent agreement between Immunomedics and
the Center. 
 (ii) To serve as a member of the Board of Directors of and to be employed (including without limitation as an
executive officer) by the Company’s majority-owned subsidiary, IBC Pharmaceuticals, Inc. (“IBC”). 
 Immunomedics acknowledges
that Dr. Goldenberg shall be entitled to spend such time as is necessary to fulfill his duties for the Center and IBC, provided that such duties do not materially interfere with his ability to perform any of his obligations under this
Agreement. Such activity on behalf of the Center, and his activity on behalf of IBC to the extent consistent with the provisions hereof, shall not be deemed a breach of this Agreement. Any salary, fees or other income paid by the Center and IBC to
Dr. Goldenberg in his respective capacity in each such entity shall be the property of Dr. Goldenberg and shall not diminish the compensation due him hereunder. 
  


 4 








 4.1. Compensation. 
 (a) Base Salary. In consideration for services rendered by Dr. Goldenberg pursuant to this Agreement, Immunomedics will pay
Dr. Goldenberg a base salary at the rate of Five Hundred Thousand Dollars ($500,000.00) per Contract Year, payable in accordance with the Company’s regular payroll procedures (the “Base Salary”). The Board or the Compensation
Committee of the Board (the “Compensation Committee”) may review Dr. Goldenberg’s Base Salary annually for appropriate increases, pursuant to the Company’s standard performance review policies for senior level executives.

 (b) Annual Bonus. Throughout the Term of this Agreement, Dr. Goldenberg will be eligible to participate in the
Company’s incentive compensation plan for senior level executives (the “Incentive Plan”) in accordance with the terms of the Incentive Plan. The Company reserves the right to amend or rescind its Incentive Plan at any time in its
discretion, but will provide Dr. Goldenberg written notice of any changes at the same time and in the same manner as other Incentive Plan participants as may be required by law or regulation. In connection with his participation in the
Incentive Plan, Dr. Goldenberg will be eligible to receive an annual discretionary bonus, as determined by the Compensation Committee, based on its assessment of Dr. Goldenberg’s individual performance and the Company’s overall
performance. Dr. Goldenberg’s Annual Bonus Target is 30% of Base Salary, with a potential Bonus ranging from 0 to 150% of the Annual Bonus Target, conditional upon his achievement of performance goals as the Compensation Committee may
establish and determine. The Compensation Committee will determine the amount of Dr. Goldenberg’s discretionary annual bonus, if any, as of the end of each fiscal year during the Term of this Agreement, and shall pay such Bonus as soon as
practicable after such determination, but in no event later than 2.5 months after the end of each fiscal year, subject to the termination provisions contained in Section 10 of this Agreement. 
  

 5 








 (c) Equity Compensation. Throughout the Term of this Agreement,
Dr. Goldenberg is eligible to receive awards pursuant to the Company’s 2006 Stock Incentive Plan or any successor equity compensation plan of the Company, in amounts as determined by the Compensation Committee. Awards granted to
Dr. Goldenberg, if any, will be subject to the provisions of the Company’s 2006 Stock Incentive Plan (including any amendments and/or successor equity plan(s) of the Company), as well as any separate option agreement, restricted stock
purchase agreement or stock award agreement between Dr. Goldenberg and the Company, which states the terms and conditions of each such award (e.g., exercise price, expiration date, vesting schedule or stock options, and any restricted period
and\or other restrictions such as performance objectives relating to stock awards). Nothing in this section shall impact or affect any equity compensation awards Dr. Goldenberg may have received at any earlier time during his Term of
Employment. 
 4.2. Additional Incentive Compensation. In recognition of Dr. Goldenberg’s past and future integral
involvement in and contribution to all aspects of Immunomedics’ scientific and creative activities, and in consideration for his agreement to forego his right set forth in the Amended Agreements to develop or dispose of Undeveloped Assets, the
Company shall make the following payments to Dr. Goldenberg as additional incentive compensation (“Additional Incentive Compensation”). 
 (a) The Additional Incentive Compensation payments to which Dr. Goldenberg is entitled include: 
 (i) Transactional Payments; Net Revenue Payments. With respect to any fiscal year during the Term of the Agreement in which Immunomedics records an annual net loss (determined by Immunomedics in a manner consistent with generally
accepted accounting principles (“GAAP”) for the entire fiscal year as audited by Immunomedics’ independent registered public 

  

 6 








 
accounting firm), Immunomedics will pay to Dr. Goldenberg a sum equal to three quarters of one percent (.75%) of the total Consideration the Company
receives from any third party transaction, excluding third party financing transactions and any Disposition of Undeveloped Assets. With respect to any fiscal year during the Term of the Agreement in which Immunomedics records positive net income
(determined by Immunomedics in a manner consistent with GAAP) for the entire fiscal year as audited by Immunomedics’ independent registered public accounting firm, Immunomedics will pay to Dr. Goldenberg a sum equal to one and one-half
percent (1.5%) of Immunomedics’ Annual Net Revenue (as defined in Section 4.2(d)) for each such fiscal year (unless Dr. Goldenberg’s employment terminates pursuant to Sections 10(a) or 10(e)), and thereafter throughout the
non-competition period (as defined in Section 9(b)); and 
 (ii) Patent Lifetime Royalty Payments. Immunomedics
will pay to Dr. Goldenberg for each full fiscal year of the Company, a sum equal to a percentage of the annual Product Royalties the Company receives each such fiscal year on each of the products for which Dr. Goldenberg is an Inventor,
and all products using, related to or derived from products for which Dr. Goldenberg is an Inventor (“Patented Products”), which payments shall continue for each Patented Product for the remaining Life of the Patent covering each
Patented Product (collectively “Patent Lifetime Royalty Payments”). The percentage of Product Royalties that Immunomedics will pay to Dr. Goldenberg on each Patented Product will be determined based on the percentage of Product
Royalties that Immunomedics must pay to external third parties (any party other than a wholly owned subsidiary of Immunomedics) on each Patented Product, as follows: 
 (A) One percent (1%) of annual Product Royalties on Patented Products for which the Company pays a Royalty of more than 9.0 %
to external third parties; 
  

 7 








 (B) One and one-half percent (1.5%) of annual Product Royalties on Patented
Products for which the Company pays a Royalty of more than 6.0 % through 9.0 % to external third parties; 
 (C)
Two percent (2%) of annual Product Royalties on Patented Products for which the Company pays a Royalty of 6.0 % or less to external third parties. 
 Patent Lifetime Royalty Payments under Section 4.2(a)(ii) shall be due and owing from Immunomedics to Dr. Goldenberg (or his
estate or designated beneficiaries) throughout the Life of each Patent both during his employment with the Company and after his employment terminates, except that Lifetime Royalty Payments shall not be payable in the event an arbitrator or court
finds that Dr. Goldenberg committed a material breach of his covenants contained in Section 9. During the Term of Dr. Goldenberg’s employment with Immunomedics only, any quarterly payment of Patent Lifetime Royalty Payments
calculated under this Section 4.2(a)(ii) will be paid to Dr. Goldenberg (or his estate or designated beneficiaries) only to the extent that such Patent Lifetime Royalty Payments exceed the quarterly Minimum Payment paid to him pursuant to
Section 4.2(c). 
 (b) Payments Upon Disposition of Undeveloped Assets. In the event the Company, with its
Board’s approval, completes a Disposition during the Term of Employment, or within three (3) years thereafter, of any one or more of Immunomedics’ Undeveloped Assets for which Dr. Goldenberg was an Inventor, Immunomedics will pay
Dr. Goldenberg a sum equal to at least twenty percent (20%), or more (as determined by the Board), of the Consideration Immunomedics receives from each Disposition, upon receipt; provided, however that no such payment shall be due in the event
an arbitrator or court finds that Dr. Goldenberg committed a material breach of his covenants contained in Section 9. Subject to the preceeding conditions, the Company’s obligation to compensate Dr. Goldenberg under this provision, if
any, applies to all Dispositions completed within the Term of Employment or within three (3) years thereafter, even if the Company actually receives the Consideration at some time after the three (3) year period elapses. 
  

 8 








 (c) Minimum Payment. Immunomedics agrees to make a minimum payment of One Hundred
Fifty Thousand Dollars ($150,000) to Dr. Goldenberg during each of Immunomedics’ fiscal years during the Term of this Agreement, payable in equal quarterly payments, as an advance against the amounts due to Dr. Goldenberg pursuant to
Section 4.2(a) and (b) above. This minimum payment shall be prorated for any partial fiscal year of Immunomedics or partial year of service of Dr. Goldenberg covered by this Section 4.2. 
 (d) Definitions. As used in this Agreement, the following terms shall have the following meanings: 
 (i) “Annual Net Revenue” means Immunomedics’ total revenue determined for the fiscal year as determined by GAAP less

reimbursement payments, and (C) any revenue generated from interest or investment income of the Company.

 9 








 
invention or development of such asset prior to such acquisition. For purposes of this definition, Immunomedics will be deemed to have materially contributed
to any product, technology or business which is covered by any Immunomedics’ patent. 
 (iii)
“Consideration” means cash, asset(s) or property, tangible or intangible, which Immunomedics receives directly or indirectly, for a Disposition (the transfer of relevant assets), including but not limited to sales proceeds, license
fees and licensing milestones, other milestone payments, up-front fees and sales bonuses. Consideration shall not include: (A) any consideration for or with respect to any Acquired Asset, (B) amounts paid to Immunomedics which clearly are
intended to constitute reimbursement of direct out-of-pocket costs incurred by Immunomedics for research, development or preclinical or clinical trials of the product or products which are the subject of the Disposition, regardless of whether paid
directly or indirectly, and however labeled, provided such amounts are paid pursuant to an agreement in effect at the time of such payment(s) and (C) any Patent Lifetime Royalty Payments (as defined in Section 4.2(a)(ii)). In calculating
the value of Consideration received in a Disposition, Immunomedics will offset the value of any thing of value that it had to grant or provide to the other party in exchange for the Disposition as an express element of the transaction. The parties
agree that any dispute with respect to the value of Consideration received in connection with any Disposition or any other dispute arising under this definition shall be submitted to arbitration pursuant to Section 8. 
 (iv) “Disposition” means any transfer, by way of sale, license or otherwise, to an unaffiliated third party, of any of
Immunomedics’ right, title or interest in or to any one or more of its products, technologies, intellectual property, businesses or other assets. Disposition includes any arrangements, whereby, Immunomedics combines with another entity and
forms a new entity in which Immunomedics holds any ownership interest and to which Immunomedics transfers, by way of sale, 

  

 10 








 
license or otherwise, any of Immunomedics’ right, title or interest in or to any one or more of its products, technologies, intellectual property, or
businesses. “Disposition” shall not include a transfer of all or substantially all of the assets or stock of Immunomedics pursuant to a Change in Control (as defined in Section 10(f)) or similar corporate transaction of Immunomedics
or to which it is a party. 
 (v) “Inventor” means a person(s) identified as an inventor of a patented
product, formula or idea on the disclosures initially filed in the relevant patent office(s) for such patent. 
 (vi)
“Life of a Patent” means the period beginning the first date on which a patent application is filed in any patent office covering any territory in the world and continuing as long as at least one (1) valid claim of the patent
exists in any territory in the world. It is understood that for purposes of this definition, the patent office in which the patent initially is filed is not likely to be located in or covering the same territory in which the last valid patent claim
remains, and that the Life of the Patent will cover all time periods between these two events. 
 (vii) “Product
Royalties” means all Consideration designated as a royalty, which Immunomedics receives for the license or use of its technology(ies), products, inventions, patents, or other intellectual property. For purposes of this Agreement, a patent

 (viii) “Immunomedics” means Immunomedics and all of its direct and indirect subsidiaries or affiliates, including but not
limited to IBC. 
 (ix) “Undeveloped Assets” means any technology, product, agent, intellectual property,

(B) has not set a time table for 

  

 11 








 
development, at a level consistent with the financial support or timetable given to any other major project or technology for which the Company currently is
budgeting for either preclinical or clinical development, (C) has not funded with substantial research and development resources, or (D) has not entered Immunomedics’ sponsored Phase I or Phase II clinical trials. 
 (x) “Code” means the Internal Revenue Code of 1986, as amended. 
 (e) In Lieu of Other Payments. The Additional Incentive Compensation discussed in Sections 4.2(a)(i) and 4.2(a)(ii) of this
Agreement shall be in lieu of all other royalties and percentage payments to which Dr. Goldenberg otherwise previously might have been entitled relative to Undeveloped Assets under the Amended Agreements or otherwise, including but not limited
to payments pursuant to the License Agreement or on any other prior agreement between the parties. 
 (f) Reports and Payments. Within forty-five (45) days after the last day of each of its fiscal quarters (other than the final quarter of each fiscal year), Immunomedics will provide Dr. Goldenberg
with a written report that includes a preliminary computation (based upon unaudited financials) of Net Revenue, of Product Royalties, and of royalties on Patented Products (computed for such quarter in the same manner as Annual Net Revenue or annual
Product Royalties is to be computed for a fiscal year) and Disposition Payments (if any), and all amounts due to Dr. Goldenberg pursuant to Sections 4.2(a)(i), 4.2(a)(ii), and 4.2(b) with respect to such fiscal quarter. Within two and one half
(2  1/2) months after the last day of each of its fiscal years, Immunomedics will provide Dr. Goldenberg with a report that
includes computation of Annual Net Revenue, of annual Product Royalties, of annual royalties on Patented Products, and Disposition Payments (if any) for the entire year and all amounts due with respect to that year (based on audited financials), as

 Immunomedics will pay or transfer to
Dr. Goldenberg, within two and one half (2  1/2) months after the last day of each of its fiscal years, all amounts due
pursuant to Sections 4.2(a)(i) and 4.2 (a)(ii) with respect to that year. Immunomedics will pay or transfer to Dr. Goldenberg any participation in Consideration to which he is entitled pursuant to Section 4.2(b) above within fifteen
(15) calendar days following receipt of such Consideration by Immunomedics, regardless of how the Company may record the receipt of such Consideration for other accounting purposes. Immunomedics will provide such documentation as
Dr. Goldenberg deems reasonably necessary to verify the Company’s calculations of the payments due to Dr. Goldenberg pursuant to Sections 4.2(a)(i), 4.2(a)(ii), and 4.2(b). At least once during each fiscal year, Dr. Goldenberg
shall have the right to obtain access to Immunomedics sales and accounting books and records, and other documents Dr. Goldenberg deems reasonably necessary to confirm Immunomedics’ compliance with its obligations under this Agreement.

 5. Vacation and Fringe Benefits. 
 (a) Vacation. Dr. Goldenberg shall be entitled to a total of six (6) weeks paid vacation during each Contract Year

 The provisions of this Section 6 shall not be applicable with respect to any research contracts for which Dr. Goldenberg may apply on behalf of the Center. 
 7. Prior Inventions and Discoveries. 
 (a) Discoveries. In exchange for Immunomedics’ agreement to provide the Additional Incentive Compensation detailed in Sections 4.2(a)(i), 4.2(a)(ii) and 4.2(b) of this Agreement, Dr. Goldenberg agrees
to forego any right to any additional compensation or consideration he otherwise would have the right to receive based on any ownership or interest he has in any and all 

  

 14 








 
ideas, inventions, improvements, discoveries, developments, products, compounds, compositions, apparatus, methods, formulae, processes, applications or uses
that he made or conceived (solely or jointly with another or others or by material contribution thereto in the course of his significant involvement in the direction of Immunomedics’ research and technology programs) during the Term of
Employment (collectively “Discoveries”). Dr. Goldenberg acknowledges that any interest he has or had in such Discoveries shall be the sole and exclusive property of Immunomedics, subject to any other applicable provisions of this
Agreement or any other agreements between the parties. 
 (i) Notwithstanding this provision, Immunomedics acknowledges that

Immunomedics’ ownership rights in and to any Discovery made or conceived by Dr. Goldenberg (solely or jointly with another or others or by material contribution thereto) in the course of any significant involvement by Dr. Goldenberg

 (ii) Notwithstanding this provision (Section 7(a)), Immunomedics further acknowledges that it does not have any interest in any
Discoveries (patented or unpatented) that Dr. Goldenberg made/makes or conceived/conceives (solely or jointly with another or others or by 

  

 15

Immunomedics or the Center, provided that such Discoveries do not involve or relate to any technologies, research, or products being produced or developed by Immunomedics or by the Center, and provided that neither Immunomedics nor the Center made
any material contribution to such Discoveries. 
 (b) Disclosures. Dr. Goldenberg acknowledges and agrees that he

 (c) Cooperation of
Dr. Goldenberg. Both during and following the Term of Employment, upon the request of Immunomedics, Dr. Goldenberg shall execute and deliver any documents and give all reasonable assistance which may be essential or desirable to secure

applications, assignments, affidavits, priority claims and other documents that Immunomedics, in its sole discretion, may determine are essential or desirable to obtain, maintain and/or defend such patents and to secure to and vest all appropriate
rights in Immunomedics. In addition, Dr. Goldenberg agrees that during and following the Term of Employment, at the request of Immunomedics, he generally will cooperate, appear and give evidence in any meetings or proceedings which may arise in
connection with Immunomedics’ efforts to secure, assign and vest for the Company the sole and exclusive right, title and interest in and to all Discoveries and other intellectual property. Immunomedics agrees to reimburse Dr. Goldenberg
for all reasonable expenses he incurs in providing 

  

 16 








 
such cooperation to Immunomedics. For purposes of this section, reasonable expenses may include but not be limited to travel costs, out of pocket expenses,
and any loss of salary or wages from another employer (if Dr. Goldenberg no longer is employed by Immunomedics). Any legal proceedings in connection with such matter shall be conducted by attorneys chosen and paid by Immunomedics.
Correspondingly, Immunomedics will provide all reciprocal support and reasonable assistance to Dr. Goldenberg that he may require to perfect his interest in any patent or Discovery, consistent with the terms of this Agreement. 
 (d) Dispute Resolution. In the event that a dispute should arise regarding whether any Discoveries are the property of
Immunomedics, or belong to the Center, if the relevant parties are not able to reach agreement, they shall submit the dispute to final and binding arbitration pursuant to Section 8 of this Agreement. 
 8. Arbitration. All disputes arising under this Agreement, other than actions to enforce the restrictions detailed in Section 9, or as
otherwise expressly stated in this Agreement, shall be subject to final and binding arbitration between the parties. Such arbitration shall be submitted to a single arbitrator selected by mutual agreement of the parties, and shall be conducted at a
mutually agreeable site located within a ten (10) mile radius of Immunomedics’ principal office in Morris Plains, New Jersey. All arbitration proceedings shall be conducted pursuant to the American Arbitration Association Rules for
Employment Disputes. 
 9. Restrictive Covenants. 
 (a) Confidentiality. Dr. Goldenberg agrees that his services to Immunomedics were and are of a special, unique and
extraordinary character, and that his position places him in a position of confidence and trust with Immunomedics’ customers and employees. Dr. Goldenberg also recognizes that his position with Immunomedics gives him substantial access to
Confidential 

  

 17 








 
Information (as defined below), the disclosure of which to competitors of Immunomedics would cause Immunomedics to suffer substantial and irreparable damage.
Therefore, Dr. Goldenberg recognizes that it is in Immunomedics’ legitimate business interest to restrict Dr. Goldenberg’s use of Confidential Information for any purposes other than the discharge of his employment duties at
Immunomedics, and to limit any potential appropriation of Confidential Information by Dr. Goldenberg for the benefit of Immunomedics’ competitors and to the detriment of Immunomedics. Accordingly, Dr. Goldenberg agrees as follows:

 (i) Throughout the Term of this Agreement and at all times thereafter, Dr. Goldenberg will not at any time reveal to
any person or entity any of the trade secrets or confidential information of Immunomedics, or of any third party, which Immunomedics is under an obligation to keep confidential (including but not limited to trade secrets and non-public information
regarding inventions, products, designs, methods, know-how, techniques, systems, processes, software programs, works of authorship, customer lists, projects, intellectual property, plans and proposals) (“Confidential Information”), except
as may be required in the ordinary course of performing Dr. Goldenberg’s duties as an employee of Immunomedics or for the benefit of Immunomedics, with the Company’s knowledge and consent. Dr. Goldenberg will keep secret all
matters entrusted to him and not use or attempt to use any Confidential Information in any manner which may injure or cause direct or indirect loss to Immunomedics. 
 (ii) Confidential Information shall not include (and the above restrictions shall not apply to): (A) information that at the time of
disclosure is in the public domain through no fault of Dr. Goldenberg; (B) information Dr. Goldenberg receives from a third party outside of Immunomedics that was disclosed without a breach of any confidentiality obligation;
(C) information approved for release by written authorization of Immunomedics; or (D) information that may be 

  

 18 








 
required by law or an order of any court, agency or proceeding to be disclosed. In the event that Dr. Goldenberg is requested or required by law or an
order of any court, agency or proceeding to disclose Confidential Information, Dr. Goldenberg will provide Immunomedics with prompt notice of such request so that Immunomedics may timely seek an appropriate protective order or waive
Dr. Goldenberg’s confidentiality obligations under this Agreement. Dr. Goldenberg will provide reasonable assistance to Immunomedics in the event the Company notifies him that it intends to seek to obtain an appropriate protective
order. If Dr. Goldenberg gives such notice to Immunomedics, but does not receive timely notice of either a protective order or a waiver from the Company and, in the written or oral opinion of his legal counsel (the reasonable fee for which
opinion shall be paid or reimbursed by Immunomedics), Dr. Goldenberg is compelled to disclose Confidential Information or face liability for contempt or other censure or penalty, then Dr. Goldenberg may disclose such Confidential
Information to the extent so required, without violating this provision or incurring any liability under the Agreement. 
 (iii) Return of Company Property. Dr. Goldenberg agrees that upon the termination of his employment with Immunomedics, regardless of the timing or reason for termination, he will not take or retain, without written
authorization, any documents, files or other property of Immunomedics. Except as provided in this Agreement, Dr. Goldenberg will return promptly to Immunomedics any such documents, files or property in his possession or custody, including any
copies thereof maintained in any medium or format. Dr. Goldenberg recognizes that all documents, files and property containing Confidential Information which he has received and will receive from Immunomedics, including but not limited to
scientific research, customer lists, handbooks, memoranda, product specifications, and other materials are for the exclusive use of Immunomedics and its employees while working on behalf of Immunomedics, and that Dr. Goldenberg has no claim or
right to the continued use, possession or custody of such documents, files or property following the termination of his employment. 
  

 19 








 Notwithstanding this provision, Immunomedics acknowledges and agrees that
Dr. Goldenberg may retain all working documents that he determines he may need with regard to any patent(s) he is preparing for filing, pursuing, or prosecuting on behalf of Immunomedics. Immunomedics further acknowledges and agrees that any
materials created prior to Dr. Goldenberg’s employment by Immunomedics, and any materials created in connection with his employment with the Center or IBC (“Non-proprietary Materials”) are not the property of Immunomedics, and
all materials that are generally available to the public and/or in the public domain (“Public Materials”), are not the exclusive property of Immunomedics. Immunomedics further agrees that Dr. Goldenberg may retain possession of all
Non-Proprietary Materials and may retain copies of all Public Materials, at all times following the end of his employment. 
 (b) Non-Competition. Throughout the Term of Employment and for a period of three (3) years thereafter, Dr. Goldenberg will not, without the prior written approval of the Board, whether alone or as a partner, officer,
director, consultant, agent, employee or stockholder of any company or other commercial enterprise, directly or indirectly engage in any business or other activity in the United States or Canada which competes with Immunomedics. The foregoing
prohibition shall not prevent Dr. Goldenberg’s employment or engagement following his Term of Employment, with any company or business organization, as long as the activities of any such employment or engagement, in any capacity, do not
involve work on matters related to the products being researched, developed, manufactured, or marketed by Immunomedics during the Term of Employment. Dr. Goldenberg shall be permitted to own securities of a public company not in excess of five
percent (5%) of any class of such securities and to own stock, partnership interests or other securities of any entity 

  

 20 








 
not in excess of five percent (5%) of any class of such securities, and to own any amount of interest in the Center, Immunomedics, and/or in IBC (or a
subsidiary or affiliate of same), and such ownership taken alone shall not be considered to be in competition with Immunomedics or a violation of this Agreement. 
 (c) Non-Solicitation. Throughout the Term of Employment and for a period of three (3) years thereafter, Dr. Goldenberg
agrees that he will not: 
 (i) directly or indirectly solicit, entice or induce any Immunomedics’ customer to become a
customer of any other person, firm or corporation with respect to products then sold or under development by Immunomedics, or to cease doing business with Immunomedics, and Dr. Goldenberg shall not approach any such person, firm or corporation
for such purpose or authorize or knowingly approve the taking of such actions by any other person; or 
 (ii) directly or
indirectly solicit or recruit any employee of Immunomedics to work for a third party other than Immunomedics (excluding the Center and excluding newspaper or similar print or electronic solicitations of general circulation); provided, however, that
the otherwise applicable non-solicitation period shall not be reduced in the event of Dr. Goldenberg’s termination for Cause or the cessation of Severance Payments as a result of Dr. Goldenberg’s violation of his obligations
under this Section 9. 
 (d) Enforcement. 
 (i) Dr. Goldenberg acknowledges and agrees that the type and periods of restrictions imposed in this Section 9 of this Agreement
are fair and reasonable, and that such restrictions are intended solely to protect the legitimate interests of Immunomedics, rather than to prevent Dr. Goldenberg from earning a livelihood. Dr. Goldenberg recognizes that Immunomedics
competes worldwide, and that his access to Confidential Information makes it necessary for Immunomedics to restrict his post-employment activities in any market in which Immunomedics competes, and in which his access to Confidential Information and
other proprietary information could be used to the detriment of Immunomedics. 
  

 21 








 (ii) Injunctive Relief. Dr. Goldenberg acknowledges and agrees that if he
breaches any of the covenants, restrictions and agreements contained in this Section 9, Immunomedics will suffer irreparable loss and injury, and that damages arising out of such a breach may be difficult to ascertain. Therefore,
Dr. Goldenberg agrees that, in addition to all other remedies provided at law or at equity, Immunomedics shall be entitled to have the covenants, restrictions and agreements contained in this Section 9 specifically enforced (including,
without limitation, by temporary, preliminary, and permanent injunctions and restraining orders) by any state or federal court in the State of New Jersey having equity jurisdiction and Dr. Goldenberg agrees to be subject to the jurisdiction of
such court. 
 (iii) Monetary Relief. In addition to its right to seek an injunction, in the event Dr. Goldenberg
breaches any provision of this Section 9, Immunomedics also shall have the right to pursue monetary damages against Dr. Goldenberg for such breach. 
 (iv) If either party fails to take action to remedy any breach of this Agreement or any portion of this Agreement by the other party, such
inaction shall not operate or be construed as a waiver of any subsequent breach by either party of the same or any other provision, agreement or covenant. 
 (v) Dr. Goldenberg acknowledges and agrees that the payments and benefits to be provided to him under this Agreement are provided, in part, as consideration for the covenants in this Section 9. 

 

 22 








 (vi) In the event that any court of competent jurisdiction or any arbitration determines
that any restriction contained in this Agreement is overly broad with respect to scope, time or geographical coverage, the parties agree that such restriction(s) may be modified and narrowed, either by a court, arbitrator, or by Immunomedics only to
the extent necessary to make this provision enforceable, and that such determination will not affect the enforceability of any other provision of this Agreement. 
 (e) Exclusions Relating to the Center. Immunomedics and Dr. Goldenberg agree that any work that Dr. Goldenberg performs
for or on behalf of the Center and/or any of its affiliates, and any documents or other confidential information or materials developed, assembled, or received while performing such work, are not subject to the provisions of this Section 9, and
that any such work will not constitute a violation of the terms of this Agreement. 
 10. Termination. Notwithstanding the provisions
of Section 2 above, the employment of Dr. Goldenberg shall terminate upon the happening of any of the following events: 
 (a) The death of Dr. Goldenberg. 
 (b) Immunomedics and Dr. Goldenberg mutually agree to terminate this
Agreement. 
 (c) At Immunomedics’ option, if Dr. Goldenberg suffers a Permanent Disability. For purposes of this
Agreement, Dr. Goldenberg shall be deemed to have incurred a “Permanent Disability” if, by reason of his physical or mental medical condition, as determined by a physician jointly designated by Immunomedics and Dr. Goldenberg, he
is unable to perform his duties under this Agreement for a period of (i) 180 consecutive days, or (ii) 245 days in any 365 consecutive days period. Dr. Goldenberg will not be deemed Permanently Disabled if he submits a written opinion
by a physician designated by or reasonably satisfactory to Immunomedics stating that Dr. Goldenberg will be able to resume continuous full-time performance of his obligations under this Agreement within 365 days following the commencement of
such disability and Dr. Goldenberg actually returns to full-time work within the same 365 day period. In the event Dr. Goldenberg and Immunomedics cannot agree 

  

 23 








 
upon a physician to determine whether Dr. Goldenberg is suffering a Permanent Disability, they each may select a physician and the two physicians so
selected will jointly select a third physician, who will examine Dr. Goldenberg to determine whether he is suffering a Permanent Disability, and will provide a written report of his/her conclusions all parties. 
 (d) By Dr. Goldenberg, for Good Reason. For purposes of this Agreement, Good Reason is defined as occurrence of any of the following
events or conditions, unless Dr. Goldenberg has expressly consented in writing thereto, or except as a result of Dr. Goldenberg’s physical or mental incapacity or as described in the last sentence of this subsection (d): 

(i) A material reduction in Dr. Goldenberg’s Base Salary; 
 (ii) The material diminution of the Dr. Goldenberg’s duties, responsibilities, powers or authorities, including the assignment
of any duties and responsibilities inconsistent with his position as Chief Scientific Officer and Chief Medical Officer of Immunomedics; or 
 (iii) Immunomedics requires that Dr. Goldenberg’s principal office location be moved to a location more than 50 miles from his principal office location immediately before the change. 
 Notwithstanding the foregoing, Dr. Goldenberg shall not have Good Reason for termination unless he gives written notice of termination for Good Reason within 15
days after the event giving rise to Good Reason occurs and Immunomedics does not correct the action or failure to act that constitutes the grounds for Good Reason, as set forth in Dr. Goldenberg’s notice of termination, within 30 days
after the date on which he gives written notice of termination. 
  

 24 








 (e) By the Company, for “Good Cause,” which means: 
 (i) Dr. Goldenberg commits continued, knowing and intentional neglect, substantial nonperformance or a demonstrated continuing
inability to perform his obligations under this Agreement (other than due to physical or mental disability) and Immunomedics provides him with written notice of such deficiencies and ninety (90) days to correct such deficiencies; or 

(ii) An arbitrator or a court finds that Dr. Goldenberg committed an act of fraud or dishonesty related to the performance of
duties under this Agreement; or 
 (iii) Dr. Goldenberg commits any material breach of any of the provisions of this
Agreement other than those covered under Sections 10(e)(i) or 10(e)(ii), and fails to cure such breach within ninety (90) days after receiving written notice from Immunomedics of such breach. 
 (f) By Dr. Goldenberg upon ninety (90) days prior written notice to Immunomedics or its successor, to be effective not later
than the second anniversary of a Change in Control of Immunomedics. For purposes of this Agreement, a Change of Control of Immunomedics is defined as: 
 (i) A merger, consolidation or reorganization approved by the Company’s stockholders, unless securities representing more than fifty percent (50%) of the total and combined voting power of the outstanding
voting securities of the successor corporation are immediately thereafter beneficially owned, directly or indirectly, by the persons who beneficially owned the Company’s outstanding voting securities immediately prior to such transaction; or

 (ii) The sale, transfer or other disposition of all or substantially all of the Company’s assets as an entirety or
substantially as an entirety, occurring within a 12-month period, and representing, at a minimum, not less than 40 percent of the total gross fair market value of all assets of the Company, to any person, entity, or group of persons acting in
consort, other than a sale, transfer or disposition to: (A) a shareholder of the Company in exchange for or with respect to its 

  

 25 








 
stock; (B) an entity, 50 percent or more of the total value or voting power of which is owned, directly or indirectly, by the Company; (C) a
person, or more than one person acting as a group, that owns, directly or indirectly, 50 percent or more of the total value or voting power of the outstanding stock of the Company; or (D) an entity, at least 50 percent of the total value or
voting power of which is owned by a person described in (C); or 
 (iii) Any transaction or series of related transactions
pursuant to which any person or any group of persons comprising a “group” within the meaning of Rule 13d-5(b)(1) under the Securities Exchange Act of 1934, as amended (other than the Company or a person that, prior to such transaction or
series of related transactions, directly or indirectly controls, is controlled by or is under common control with, the Company) becomes directly or indirectly the beneficial owner (within the meaning of Rule 13d-3 of the Securities Exchange Act of
1934, as amended) of securities possessing (or convertible into or exercisable for securities possessing) more than fifty percent (50%) of the total combined voting power of the Company’s securities outstanding immediately after the
consummation of such transaction or series of related transactions, whether such transaction involves a direct issuance from the Company or the acquisition of outstanding securities held by one or more of the Company’s stockholders; or

 (iv) A change in the composition of the Board over a period of twelve (12) consecutive months or less such that a
majority of the Board members ceases by reason of one or more contested elections for Board membership to be comprised of individuals whose election is endorsed by a majority of the members of the Board immediately before the date of election.

  

 26 








 A transaction shall not constitute a Change of Control if its sole purpose is to change the state of the Company’s
incorporation or to create a holding company that will be owned in the same proportions by the persons who held the Company’s securities immediately before such transaction. 
 (g) Except as provided in Sections 10(a), 10(c) or 10(e)(ii), with respect to death, Permanent Disability and fraud/dishonesty,
respectively, termination by either party hereunder shall be effective upon the effective date of notice of such termination by the terminating party to the other party specifying the reasons, if any, for such termination. 
 (h) The foregoing provisions of this Section 10 notwithstanding, Dr. Goldenberg will not be deemed to have had a termination of
employment prior to the date as of which Immunomedics and Dr. Goldenberg reasonably anticipate that the level of future services to be provided by Dr. Goldenberg to Immunomedics, whether as an employee or an independent contractor, will
permanently decrease to a level which is less than fifty (50) percent of the average level of services provided over the immediately preceding thirty-six (36) months. 
 11. Decisions and Determinations of the Board. Neither Dr. Goldenberg nor any of his affiliates shall participate in any decision by the
Board, or any Board committee, which affects any of his rights or obligations under this Agreement. Except as otherwise expressly provided in this Agreement, all actions of the Board provided for in this Agreement, including but not limited to
determinations, consents and approvals, shall be in the Board’s sole and uncontrolled discretion. 
 12. Cooperation with
Immunomedics After Expiration or Termination. Following the end of the Term of Employment, regardless of timing or cause, Dr. Goldenberg will cooperate fully with Immunomedics in all matters relating to the winding up of work on behalf of
Immunomedics and the orderly transfer of any pending work to other employees of Immunomedics. Dr. Goldenberg agrees to be available and to provide services on a full-time or part-time basis, as Immunomedics may request, 

  

 27 








 
during the first thirty (30) calendar days following the end of his employment. In consideration for the Patent Lifetime Royalty Payments set out in
Section 4.2(a)(ii) of this Agreement, Dr. Goldenberg specifically agrees to provide to Immunomedics all assistance reasonably necessary to assist Immunomedics in defending and prosecuting any patents in force. This obligation will continue
for the life of the patent, provided Dr. Goldenberg is medically able to provide such assistance. Nothing herein shall limit Immunomedics’ obligation to pay, and Dr. Goldenberg’s or his estate’s right to receive, the
Additional Incentive Compensation, Patent Lifetime Royalty Payments and Disposition Payments under Sections 4.2(a)(ii) and 4.2(b) of this Agreement, for the specified periods or throughout the Life of the Patents, as the case may be. 
 13. Payment and Benefits on Termination or Expiration. 
 (a) Disability and Death. Immunomedics, with the full cooperation of Dr. Goldenberg, shall acquire and provide for life
insurance for Dr. Goldenberg as required under Section 5(d) and Exhibit A of this Agreement. Such insurance shall remain in full force and effect (i) for the Term of this Agreement and (ii) for three (3) years after the Term
of this Agreement, unless Dr. Goldenberg initiates early termination other than for Good Reason (as defined in Section 10(d) or 10(f)), or Immunomedics initiates early termination for Good Cause (as defined in Section 10(e)).

 (b) Guaranteed Payments. Not later than sixty (60) days following the termination of Dr. Goldenberg’s
employment, regardless of the reason or timing of the termination, Immunomedics will make payment to Dr. Goldenberg for all annual Base Salary, Bonus, Minimum Payments, and Additional Incentive Compensation earned through the date of
termination, any benefits accrued in accordance with the terms of any applicable benefit plans and programs of the Company (including but not limited to earned but unused vacation), and will continue all payments pursuant to Section 4.2(a)(ii)
and 4.2(b) for the time periods provided in those sections of this Agreement (collectively, “Guaranteed Payments”). There are no preconditions to Immunomedics’ obligation to pay, and to Dr. Goldenberg’s right to receive,
Guaranteed Payments under this Section 13(b) of this Agreement. 
  

 28 








 (c) Severance 
 (i) If Dr. Goldenberg’s employment terminates pursuant to Section 10(a) (death), in addition to receiving the Guaranteed
Payments, his estate will receive a Severance Payment equal to the amount of the Annual Target Bonus, if any, (pursuant to Section 4.1(b)) payable for the fiscal year in which the termination occurs (prorated to reflect
Dr. Goldenberg’s actual period of service during such fiscal year), such amount to be paid within sixty (60) days following the date of Dr. Goldenberg’s death. 
 (ii) If Dr. Goldenberg’s employment terminates by mutual agreement of the parties pursuant to Section 10(b) (mutual
agreement), 10(c) (permanent disability) or pursuant to expiration or non-renewal as set forth in Section 2, in addition to receiving the Guaranteed Payments, Dr. Goldenberg will receive payment for the Annual Target Bonus, if any,
(pursuant to Section 4.1(b)) payable for the fiscal year in which the termination occurs (prorated to reflect Dr. Goldenberg’s actual period of service during such fiscal year), such amount to be paid within sixty (60) days
following the date of termination of employment, and any other benefits or payments to which the parties may agree. 
 (iii)
If Dr. Goldenberg’s employment terminates for Good Cause pursuant to Section 10(e), the only post-termination payment or benefit he will receive is the Guaranteed Payments. 
 (iv) If Immunomedics terminates Dr. Goldenberg’s employment without Good Cause (as defined in Section 10(e), or if
Dr. Goldenberg terminates his employment for Good Reason pursuant to Section 10(d), in addition to the Guaranteed Payments, Immunomedics will pay Dr. Goldenberg Severance payments in an amount equal to his Total Annual Compensation
(as such 

  

 29 








 
exists as of the date of termination), paid or provided for the remaining balance of the Term of this Agreement on the same schedule as would apply if
Dr. Goldenberg remained an active employee of Immunomedics, plus an additional lump sum amount equal to two times (2x) his Total Annual Compensation (as such exists as of the date of termination), such lump sum to be paid within sixty
(60) days following the date of termination of Dr. Goldenberg’s employment. “Total Annual Compensation” shall include all cash payments due to Dr. Goldenberg for the applicable Contract Year as set out in
Sections 4.1(a) and (b), 4.2(a)(i), and 4.2(c), but shall not include payments provided pursuant to Sections 4.2(a)(ii) and 4.2(b) (which shall continue pursuant to the terms of those Sections). 
 (A) In the event Dr. Goldenberg’s employment terminates as provided in Section 13(c)(iv), for the balance of the Term of
this Agreement and for a period of two (2) years following the end of the Term of this Agreement (the “Severance Period”), the Company will, to the extent permitted under Section 409A of the Code, continue to provide to
Dr. Goldenberg all of the benefits of his employment, as if he remained employed, as set as in Sections 4.1(c), 5(b), 5(c) and 5(d). Immunomedics shall, during the Severance Period and for a period of eighteen (18) months thereafter, pay
Dr. Goldenberg each month an amount equal to the monthly COBRA medical insurance cost under Immunomedic’s medical plan for Dr. Goldenberg and any eligible dependent(s) (less any required employee payments calculated as if
Dr. Goldenberg had continued to be an employee), and all other employee benefits pursuant to Section 5(c) and all life insurance policies pursuant to Section 5(d) and Exhibit A. Throughout the Severance Period, Immunomedics also will
pay for the reasonable cost of an office and secretarial support for Dr. Goldenberg, and all reasonable expenses to set up and maintain such office (including telephone, fax and Internet access, office supplies and equipment, furniture, etc.),
at a reasonable location of Dr. Goldenberg’s choice. 
  

 30 








 (v) If Dr. Goldenberg terminates his employment following a Change in Control
pursuant to Section 10(f), in addition to the Guaranteed Payments, Immunomedics will pay Dr. Goldenberg, with sixty (60) days following the date of his termination of employment, a Severance payment in an amount equal to a lump sum
amount equal to three times (3x) his Total Annual Compensation, as previously defined above, (as such exists as of the date of termination). 
 (A) In the event Dr. Goldenberg’s employment terminates as provided in Section 13(c)(v), for the balance of the Term of this Agreement and for or a period of three (3) years following the end of
the Term of this Agreement (the “Enhanced Severance Period”), the Company or its successor, as the case may be, will continue to provide to Dr. Goldenberg all of the benefits of his employment, as if he remained employed, as set out
in Sections 4.1(c), 5(b), 5(c) and 5(d). Immunomedics shall, during the Enhanced Severance Period and for a period of eighteen (18) months thereafter, pay Dr. Goldenberg each month an amount equal to the monthly COBRA medical insurance
cost under Immnunomedics medical plan for Dr. Goldenberg and any eligible dependent(s) (less any required employee payments calculated as if Dr. Goldenberg had continued to be an employee), and all other employee benefits pursuant to
Section 5(c) and all life insurance policies pursuant to Section 5(d) and Exhibit A. Throughout the Enhanced Severance Period, Immunomedics also will pay for the reasonable cost of an office and secretarial support for Dr. Goldenberg,
and all reasonable expenses to set up and maintain such office (including telephone, fax and Internet access, office supplies and equipment, furniture, etc.), at a reasonable location of Dr. Goldenberg’s choice. 
  

 31 








 (d) In the event Dr. Goldenberg should expire during either Severance Period,
Immunomedics will continue to make all Severance Cash Payments to his estate through the end of the Severance Period, continue to pay his estate a monthly amount for the cost of medical coverage for Dr. Goldenberg’s eligible dependents in
accordance with Sections 13(c)(iv)(A) or 13(c)(v)(A), as applicable, and will continue to pay all Patent Lifetime Royalty Payments under Section 4.2(a)(ii) for the Life of each Patent. 
 (e) Specific Issues in the Event of a Change in Control (regardless of whether Dr. Goldenberg terminates his employment): 

(i) Notwithstanding any provision to the contrary in the Company’s 2006 Stock Incentive Plan or any applicable plan, program or
agreement, upon the occurrence of a Change of Control, all stock options, restricted stock and other equity rights held by Dr. Goldenberg will become fully vested and/or exercisable, as the case may be, on the date on which the Change in
Control occurs, and all stock options held by Dr. Goldenberg shall remain exercisable, notwithstanding anything in any other agreement governing such options, for a period of twenty-four (24) months following the end of the remaining
balance of the Term of the Agreement; provided, however, that in no event will the option be exercisable (a) beyond its original term; or (b) beyond the extension period permitted under Section 409A of the Code. 
 (ii) Notwithstanding any provision to the contrary in any applicable plan, program or agreement providing for supplemental retirement
benefits or deferred compensation, upon the occurrence of a Change of Control, Dr. Goldenberg’s accrued benefit under such plans, programs or agreements shall become fully vested on the date on which the Change in Control occurs, and shall
be immediately payable on Dr. Goldenberg’s date of termination, unless Dr. Goldenberg has made a valid election under such plan, program or agreement to defer payment of such accrued benefits. 
  

 32 








 (iii) Increase in Payments Upon a Change of Control. 
 (A) Notwithstanding anything in this Agreement to the contrary, in the event that it shall be determined that any payment or distribution
by the Company to or for the benefit of Dr. Goldenberg, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (a “Payment”), would constitute an “excess parachute
payment” within the meaning of Section 280G of the Code, the Company shall pay to Dr. Goldenberg an additional amount (the “Gross-Up Payment”) such that the net amount retained by Dr. Goldenberg after deduction of any
excise tax imposed under Section 4999 of the Code, and any federal, state and local income tax, employment tax and excise tax imposed upon the Gross-Up Payment, shall be equal to the Payment. For purposes of determining the amount of the
Gross-Up Payment, unless Dr. Goldenberg specifies that other rates apply, Dr. Goldenberg shall be deemed to pay federal income tax and employment taxes at the highest marginal rate of federal income and employment taxation in the calendar
year in which the Gross-Up Payment is to be made and state and local income taxes at the highest marginal rate of taxation in the state and locality of Dr. Goldenberg’s residence on his termination date, net of the maximum reduction in
federal income taxes that may be obtained from the deduction of such state and local taxes. 
 (B) All determinations to be
made under this Section shall be made by the Company’s independent public accountant immediately prior to the Change of Control or by another independent public accounting firm mutually selected by the Company and Dr. Goldenberg before the
date of the Change of Control (the “Accounting Firm”), which firm shall provide its determinations and any supporting calculations both to the Company and Dr. Goldenberg within 20 days after Dr. Goldenberg’s termination date. Any
such determination by the Accounting Firm shall be binding upon the Company and Dr. Goldenberg. 
  

 33 








 (C) The Company shall pay the Gross-Up Payment as and when the related excise tax under
section 4999 of the Code (“Excise Tax”) is incurred. The Gross-Up Payment shall be paid in accordance with Section 409A of the Code, to the extent applicable. If required in order to comply with Section 409A of the Code,
(i) the Gross-Up Payment attributable to Payments other than severance compensation shall be paid in a lump sum payment upon the closing of the Change of Control, subject to Section 19(c) of this Agreement, if applicable, and (ii) the
Gross-Up Payment attributable to severance compensation shall be paid in a lump sum payment on the first day on which severance compensation is paid. If the amount of a Gross-Up Payment cannot be fully determined by the date on which the applicable
portion of the Payment becomes subject to the Excise Tax (“Payment Date”), the Company shall pay to Dr. Goldenberg by the Payment Date an estimate of such Gross-Up Payment, as determined by the Accounting Firm, and the Company shall
pay to Dr. Goldenberg the remainder of such Gross-Up Payment (if any) as soon as the amount can be determined, but in no event later than 20 days after the Payment Date. 
 (D) All of the fees and expenses of the Accounting Firm in performing the determinations referred to in this Section shall be borne
solely by the Company. The Company agrees to indemnify and hold harmless the Accounting Firm from any and all claims, damages and expenses resulting from or relating to its determinations pursuant to this Section, except for claims, damages or
expenses resulting from the gross negligence or willful misconduct of the Accounting Firm. 
  

 34 








 (f) Required Postponement for Specified Executives. 
 (i) If Dr. Goldenberg is considered a Specified Executive (as defined below) and payment of any amounts under this Agreement is
required to be delayed for a period of six months after separation from service pursuant to Section 409A of the Code, payment of such amounts shall be delayed as required by Section 409A, and the accumulated postponed amounts, with accrued
interest as described below, shall be paid in a lump sum payment within five days after the end of the six month period. If Dr. Goldenberg dies during the postponement period prior to the payment of benefits, the amounts postponed on account of
Section 409A, with accrued interest as described in subsection (b) below, shall be paid to the personal representative of Dr. Goldenberg’s estate within 60 days after the date of Dr. Goldenberg’s death. 
 (ii) If payment of any amounts under this Agreement is required to be delayed pursuant to section 409A of the Code, the Company shall pay
interest on the postponed payments from the date on which the amounts otherwise would have been paid to the date on which such amounts are paid at an annual rate equal to the rate published in the Wall Street Journal as the “prime rate” as
of Dr. Goldenberg’s date of termination. 
 (iii) The term “Specified Executive” means an employee who, at
