Grant No.: _____

INCENTIVE STOCK OPTION AGREEMENT

UNDER THE

IMMUNOMEDICS, INC. 2014 LONG-TERM INCENTIVE PLAN

1.          Terminology.  Capitalized terms used in this Agreement are defined in the correlating Stock Option Notice and/or the Glossary at the end of the Agreement.

2.          Exercise of Options.

(a)         Exercisability.  The Options will become exercisable in accordance with the Exercisability Schedule set forth in the Stock Option Notice, so long as you are in the Service of the Company from the Grant Date through the applicable exercisability dates.  None of the Options will become exercisable after your Service with the Company ceases, unless the Stock Option Notice provides otherwise with respect to exercisability that arises as a result of your cessation of Service.

(b)         Right to Exercise.  You may exercise the Options, to the extent exercisable, at any time on or before 5:00 P.M. Eastern Time on the Expiration Date or the earlier termination of the Options, unless otherwise provided under applicable law.  Notwithstanding the foregoing, if at any time the Administrator determines that the delivery of Shares under the Plan or this Agreement is or may be unlawful under the laws of any applicable jurisdiction, or federal, state or foreign securities laws, the right to exercise the Options or receive Shares pursuant to the Options shall be suspended until the Administrator determines that such delivery is lawful.  If at any time the Administrator determines that the delivery of Shares under the Plan or this Agreement is or may violate the rules of the national securities exchange on which the shares are then listed for trade, the right to exercise the Options or receive Shares pursuant to the Options shall be suspended until the Administrator determines that such exercise or delivery would not violate such rules.  Section 3 below describes certain limitations on exercise of the Options that apply in the event of your death, Total and Permanent Disability, or termination of Service.  The Options may be exercised only in multiples of whole Shares and may not be exercised at any one time as to fewer than one hundred Shares (or such lesser number of Shares as to which the Options are then exercisable).  No fractional Shares will be issued under the Options.

(c)         Exercise Procedure.  In order to exercise the Options, you must provide the following items to the Secretary of the Company or his or her delegate before the expiration or termination of the Options:

(i)          notice, in such manner and form as the Administrator may require from time to time, specifying the number of Shares to be purchased under the Options; and

(ii)         full payment of the Exercise Price for the Shares or properly executed, irrevocable instructions, in such manner and form as the Administrator may require from time to time, to effectuate a broker-assisted cashless exercise, each in accordance with Section 2(d) of this Agreement.

An exercise will not be effective until the Secretary of the Company or his or her delegate receives all of the foregoing items, and such exercise otherwise is permitted under and complies with all applicable federal, state and foreign securities laws.  Notwithstanding the foregoing, if the Administrator permits payment by means of delivering properly executed, irrevocable instructions, in such manner and form as the Administrator may require from time to time, to effectuate a

broker-assisted cashless exercise and such instructions provide for sale of Shares under a limit order rather than at the market, the exercise will not be effective until the earlier of the date the Company receives delivery of cash or cash equivalents in full payment of the Exercise Price or the date the Company receives confirmation from the broker that the sale instruction has been fulfilled, and the exercise will not be effective unless the earlier of such dates occurs on or before termination of the Options.

(d)         Method of Payment.  You may pay the Exercise Price by:

(i)          delivery of cash, certified or cashier’s check, money order or other cash equivalent acceptable to the Administrator in its discretion;

(ii)         a broker-assisted cashless exercise in accordance with Regulation T of the Board of Governors of the Federal Reserve System through a brokerage firm designated or approved by the Administrator;

(iii)         subject to such limits as the Administrator may impose from time to time, tender (via actual delivery or attestation) to the Company of other shares of Common Stock of the Company which have a Fair Market Value on the date of tender equal to the Exercise Price;

(iv)        subject to such limits as the Administrator may impose from time to time, net share settlement with respect to any portions of the Options that do not qualify as incentive stock options within the meaning of Code section 422;

(v)         any other method approved by the Administrator; or

(vi)        any combination of the foregoing.

(e)         Issuance of Shares upon Exercise.  The Company shall issue to you the Shares underlying the Options you exercise as soon as practicable after the exercise date, subject to the Company’s receipt of the aggregate exercise price and the requisite withholding taxes, if any.  Upon issuance of such Shares, the Company may deliver, subject to the provisions of Section 7 below, such Shares on your behalf electronically to the Company’s designated stock plan administrator or such other broker-dealer as the Company may choose at its sole discretion, within reason, or may retain such Shares in uncertificated book-entry form.  Any share certificates delivered will, unless the Shares are registered or an exemption from registration is available under applicable federal and state law, bear a legend restricting transferability of such Shares.

3.          Termination of Service.

(a)         Termination of Unexercisable Options.  If your Service with the Company ceases for any reason, the Options that are then unexercisable, after giving effect to any exercise acceleration provisions set forth on the Stock Option Notice, will terminate immediately upon such cessation.

(b)         Exercise Period Following Termination of Service.  If your Service with the Company ceases for any reason other than discharge for Cause, the Options that are then exercisable, after giving effect to any exercise acceleration provisions set forth on the Stock Option Notice, will terminate upon the earliest of:

(i)          the expiration of 90 days following such cessation, if your Service ceases on account of (1) your termination by the Company other than a discharge for Cause, or (2) your voluntary termination other than for Total and Permanent Disability or death;

(ii)         the expiration of 12 months following such cessation, if your Service ceases on account of your Total and Permanent Disability or death;

(iii)         the expiration of 12 months following your death, if your death occurs during the periods described in clauses (i) or (ii) of this Section 3(b), as applicable; or

(iv)        the Expiration Date.

In the event of your death, the exercisable Options may be exercised by your executor, personal representative, or the person(s) to whom the Options are transferred by will or the laws of descent and distribution.

(c)         Misconduct.  The Options will terminate in their entirety, regardless of whether the Options are then exercisable, immediately upon your discharge from Service for Cause, or upon your commission of any of the following acts during the exercise period following your termination of Service: (i) fraud on or misappropriation of any funds or property of the Company, or (ii) your breach of any provision of any employment, non-disclosure, non-competition, non-solicitation, assignment of inventions, or other similar agreement executed by you for the benefit of the Company, as determined by the Administrator, which determination will be conclusive.

(d)         Changes in Status.  If you cease to be a “common law employee” of the Company but you continue to provide bona fide services to the Company following such cessation in a different capacity, including without limitation as a director, consultant or independent contractor, then a termination of Service shall not be deemed to have occurred for purposes of this Section 3 upon such change in capacity.  Notwithstanding the foregoing, the Options shall not be treated as incentive stock options within the meaning of Code section 422 with respect to any exercise that occurs more than three months after such cessation of the common law employee relationship (except as otherwise permitted under Code section 421 or 422).  In the event that your Service is with a business, trade or entity that, after the Grant Date, ceases for any reason to be part or an Affiliate of the Company, your Service will be deemed to have terminated for purposes of this Section 3 upon such cessation if your Service does not continue uninterrupted immediately thereafter with the Company or an Affiliate of the Company.

4.          Nontransferability of Options.  These Options and, before exercise, the underlying Shares are nontransferable otherwise than by will or the laws of descent and distribution and during your lifetime, the Options may be exercised only by you or, during the period you are under a legal disability, by your guardian or legal representative.  Except as provided above, the Options may not be assigned, transferred, pledged, hypothecated or disposed of in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process.

5.          Qualified Nature of the Options.

(a)         General Status.  The Options are intended to qualify as incentive stock options within the meaning of Code section 422 (“Incentive Stock Options”), to the fullest extent permitted by Code section 422, and this Agreement shall be so construed.  The Company, however, does not warrant any particular tax consequences of the Options.  Code section 422 provides limitations, not set forth in this Agreement, respecting the treatment of the Options as Incentive Stock Options.  You should consult with your personal tax advisors in this regard.

(b)         Code Section 422(d) Limitation.  Pursuant to Code section 422(d), the aggregate fair market value (determined as of the Grant Date) of shares of Common Stock with respect to which all Incentive Stock Options first become exercisable by you in any calendar year under the Plan or any other plan of the Company (and its parent and subsidiary corporations, within the meaning of Code section 424(e) and (f), as may exist from time to time) may not exceed $100,000 or such other amount as may be permitted from time to time under Code section 422.  To the extent that such aggregate fair market value exceeds $100,000 or other

applicable amount in any calendar year, such stock options will be treated as nonstatutory stock options with respect to the amount of aggregate fair market value thereof that exceeds the Code section 422(d) limit.  For this purpose, the Incentive Stock Options will be taken into account in the order in which they were granted.  In such case, the Company may designate the shares of Common Stock that are to be treated as stock acquired pursuant to the exercise of Incentive Stock Options and the shares of Common Stock that are to be treated as stock acquired pursuant to nonstatutory stock options by issuing separate certificates for such shares and identifying the certificates as such in the stock transfer records of the Company.

(c)         Significant Stockholders.  Notwithstanding anything in this Agreement or the Stock Option Notice to the contrary, if you own, directly or indirectly through attribution, stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of any of its subsidiaries (within the meaning of Code section 424(f)) on the Grant Date, then the Exercise Price is the greater of (a) the Exercise Price stated on the Stock Option Notice or (b) 110% of the Fair Market Value of the Common Stock on the Grant Date, and the Expiration Date is the last business day prior to the fifth anniversary of the Grant Date.

(d)         Disqualifying Dispositions.  If you make a disposition (as that term is defined in Code section 424(c)) of any Shares acquired pursuant to the Options within two years of the Grant Date or within one year after the Shares are transferred to you, you must notify the Company of such disposition in writing within 30 days of the disposition.  The Administrator may, in its discretion, take reasonable steps to ensure notification of such dispositions, including but not limited to requiring that Shares acquired under the Options be held in an account with a Company-designated broker-dealer until they are sold.

6.          Withholding of Taxes.

(a)         At the time the Options are exercised, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll or any other payment of any kind due to you and otherwise agree to make adequate provision for foreign, federal, state and local taxes required by law to be withheld, if any, which arise in connection with the Options (including upon a disqualifying disposition within the meaning of Code section 421(b)).  The Company may require you to make a cash payment to cover any withholding tax obligation as a condition of exercise of the Options or issuance of share certificates representing Shares.

(b)         The Administrator may, in its sole discretion, permit you to satisfy, in whole or in part, any withholding tax obligation which may arise in connection with the Options either by electing to have the Company withhold from the Shares to be issued upon exercise that number of Shares, or by electing to deliver to the Company already-owned shares, in either case having a Fair Market Value not in excess of the amount necessary to satisfy the statutory minimum withholding amount due.

7.          Adjustments.  The Administrator may make various adjustments to your Options, including adjustments to the number and type of securities subject to the Options and the Exercise Price, in accordance with the terms of the Plan. In the event of any transaction resulting in a Change in Control (as defined in the Plan) of the Company, the outstanding Options will terminate upon the effective time of such Change in Control unless provision is made in connection with the transaction for the continuation or assumption of such Options by, or for the substitution of the equivalent awards of, the surviving or successor entity or a parent thereof.  In the event of such termination, you will be permitted, immediately before the Change in Control, to exercise or convert all portions of such Options that are then exercisable or which become exercisable upon or prior to the effective time of the Change in Control.

8.          Non-Guarantee of Employment or Service Relationship.  Nothing in the Plan or this Agreement will alter your at-will or other employment status or other service relationship with

the Company, nor be construed as a contract of employment or service relationship between you and the Company, or as a contractual right for you to continue in the employ of, or in a service relationship with, the Company for any period of time, or as a limitation of the right of the Company to discharge you at any time with or without Cause or notice and whether or not such discharge results in the failure of any of the Options to become exercisable or any other adverse effect on your interests under the Plan.

9.          No Rights as a Stockholder.  You shall not have any of the rights of a stockholder with respect to the Shares until such Shares have been issued to you upon the due exercise of the Options.  No adjustment will be made for dividends or distributions or other rights for which the record date is prior to the date such Shares are issued.

10.        The Company’s Rights.  The existence of the Options shall not affect in any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company's capital structure or its business, or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or other stocks with preference ahead of or convertible into, or otherwise affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of the Company's assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

11.        Entire Agreement.  This Agreement, together with the correlating Stock Option Notice and the Plan, contain the entire agreement between you and the Company with respect to the Options.  Any oral or written agreements, representations, warranties, written inducements, or other communications made prior to the execution of this Agreement with respect to the Options shall be void and ineffective for all purposes.

12.        Amendment.  This Agreement may be amended from time to time by the Administrator in its discretion; provided,  however, that this Agreement may not be modified in a manner that would have a materially adverse effect on the Options or Shares as determined in the discretion of the Administrator, except as provided in the Plan or in a written document signed by you and the Company.

13.        Conformity with Plan.  This Agreement is intended to conform in all respects with, and is subject to all applicable provisions of, the Plan.  Any conflict between the terms of this Agreement and the Plan shall be resolved in accordance with the terms of the Plan.  In the event of any ambiguity in this Agreement or any matters as to which this Agreement is silent, the Plan shall govern.  A copy of the Plan is available upon request to the Administrator.

14.        Section 409A.  This Agreement and the Options granted hereunder are intended to comply with, or otherwise be exempt from, Section 409A of the Code.  This Agreement and the Options shall be administered, interpreted and construed in a manner consistent with this intent.  Nothing in the Plan or this Agreement shall be construed as including any feature for the deferral of compensation other than the deferral of recognition of income until the exercise of the Options.  Should any provision of the Plan or this Agreement be found not to comply with, or otherwise be exempt from, the provisions of Section 409A of the Code, it may be modified and given effect, in the sole discretion of the Administrator and without requiring your consent, in such manner as the Administrator determines to be necessary or appropriate to comply with, or to effectuate an exemption from, Section 409A of the Code.  The foregoing, however, shall not be construed as a guarantee or warranty by the Company of any particular tax effect to you.

15.        Electronic Delivery of Documents.  By your signing the Notice, you (i) consent to the electronic delivery of this Agreement, all information with respect to the Plan and the Options, and any reports of the Company provided generally to the Company’s stockholders; (ii) acknowledge that you may receive from the Company a paper copy of any documents delivered electronically at no cost to you by contacting the Company by telephone or in writing; (iii) further acknowledge that you may revoke your consent to the electronic delivery of

documents at any time by notifying the Company of such revoked consent by telephone, postal service or electronic mail;and (iv) further acknowledge that you understand that you are not required to consent to electronic delivery of documents.

16.        No Future Entitlement.  By execution of the Notice, you acknowledge and agree that:  (i) the grant of these Options is a one-time benefit which does not create any contractual or other right to receive future grants of stock options, or compensation in lieu of stock options, even if stock options have been granted repeatedly in the past; (ii) all determinations with respect to any such future grants, including, but not limited to, the times when stock options shall be granted or shall become exercisable, the maximum number of shares subject to each stock option, and the purchase price, will be at the sole discretion of the Administrator; (iii) the value of these Options is an extraordinary item of compensation which is outside the scope of your employment contract, if any; (iv) the value of these Options is not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculating any termination, severance, resignation, redundancy, end of service payments or similar payments, or bonuses, long-service awards, pension or retirement benefits; (v) the vesting of these Options ceases upon termination of employment with the Company or transfer of employment from the Company, or other cessation of eligibility for any reason, except as may otherwise be explicitly provided in this Agreement; (vi) if the underlying Common Stock does not increase in value, these Options will have no value, nor does the Company guarantee any future value; and (vii) no claim or entitlement to compensation or damages arises if these Options do not increase in value and you irrevocably release the Company from any such claim that does arise.

17.        Personal Data.  For the purpose of implementing, administering and managing these Options, you, by execution of the Notice, consent to the collection, receipt, use, retention and transfer, in electronic or other form, of your personal data by and among the Company and its third party vendors or any potential party to any Change in Control transaction or capital raising transaction involving the Company.  You understand that personal data (including but not limited to, name, home address, telephone number, employee number, employment status, social security number, tax identification number, date of birth, nationality, job and payroll location, data for tax withholding purposes and shares awarded, cancelled, exercised, vested and unvested) may be transferred to third parties assisting in the implementation, administration and management of these Options and the Plan and you expressly authorize such transfer as well as the retention, use, and the subsequent transfer of the data by the recipient(s).  You understand that these recipients may be located in your country or elsewhere, and that the recipient’s country may have different data privacy laws and protections than your country.  You understand that data will be held only as long as is necessary to implement, administer and manage these Options.  You understand that you may, at any time, request a list with the names and addresses of any potential recipients of the personal data, view data, request additional information about the storage and processing of data, require any necessary amendments to data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing the Company’s Secretary.  You understand, however, that refusing or withdrawing your consent may affect your ability to accept a stock option.

18.        Governing Law. The validity, construction and effect of this Agreement, and of any determinations or decisions made by the Administrator relating to this Agreement, and the rights of any and all persons having or claiming to have any interest under this Agreement, shall be determined exclusively in accordance with the laws of the State of Delaware, without regard to its provisions concerning the applicability of laws of other jurisdictions.  As a condition of this Agreement, you agree that you will not bring any action arising under, as a result of, pursuant to or relating to, this Agreement in any court other than a federal or state court in New Jersey, and you hereby agree and submit to the personal jurisdiction of any federal or state court in New Jersey.  You further agree that you will not deny or attempt to defeat such personal jurisdiction or object to venue by motion or other request for leave from any such court.

19.        Resolution of Disputes.  Any dispute or disagreement which shall arise under, or as a result of, or pursuant to or relating to, this Agreement shall be determined by the

Administrator in good faith in its absolute and uncontrolled discretion, and any such determination or any other determination by the Administrator under or pursuant to this Agreement and any interpretation by the Administrator of the terms of this Agreement, will be final, binding and conclusive on all persons affected thereby.  You agree that before you may bring any legal action arising under, as a result of, pursuant to or relating to, this Agreement you will first exhaust your administrative remedies before the Administrator.  You further agree that in the event that the Administrator does not resolve any dispute or disagreement arising under, as a result of, pursuant to or relating to, this Agreement to your satisfaction, no legal action may be commenced or maintained relating to this Agreement more than twenty-four (24) months after the Administrator’s decision.
