IMMUNOMEDICS, INC.

RESTRICTED STOCK UNIT ISSUANCE AGREEMENT

RECITALS

A. The Plan is to designed to provide equity incentives to selected Employees, non-employee Board members and consultants and other independent advisors in order to attract and retain their services for the Corporation (or any Parent or Subsidiary).

B. The Participant is a non-employee Board member to whom an equity incentive award is to be made pursuant to the Automatic Grant Program under the Plan.

C. All capitalized terms in this Agreement shall have the meaning assigned to them in the attached Appendix A.

NOW, THEREFORE, it is hereby agreed as follows:

1. Grant of Restricted Stock Units. The Participant is hereby awarded, as of the Award Date, Restricted Stock Units under the Automatic Grant Program. Each Restricted Stock Unit represents the right to receive one share of Common Stock on the vesting date of that Unit. The number of shares of Common Stock subject to the awarded Restricted Stock Units, the applicable vesting schedule for those shares, the dates on which those vested shares shall become issuable to the Participant and the remaining terms and conditions governing the award (the “Award”) shall be as set forth in this Agreement.

AWARD SUMMARY

2. Limited Transferability. Prior to the actual issuance of the Shares which vest hereunder, the Participant may not transfer any interest in the Award or the underlying Shares, except to the limited extent otherwise provided in this Paragraph 2. Any Shares which vest hereunder but which otherwise remain unissued at the time of the Participant’s death may be transferred pursuant to the provisions of the Participant’s will or the laws of inheritance or to the

Participant’s designated beneficiary or beneficiaries of this Award. The Participant may also direct the Corporation to issue the stock certificates for any Shares which in fact vest and become issuable under the Award during his or her lifetime to one or more designated Family Members or a trust established for the Participant and/or his or her Family Members. The Participant may make such a beneficiary designation or certificate directive at any time by filing the appropriate form with the Plan Administrator or its designee.

3. Cessation of Service. Should the Participant cease service as a Board member for any reason prior to vesting in one or more Shares subject to this Award, then the Award will, except to the extent the special vesting acceleration provisions of Paragraph 5 (b) are otherwise applicable, be immediately cancelled with respect to those unvested Shares, and the number of Restricted Stock Units will be reduced accordingly. The Participant shall thereupon cease to have any right or entitlement to receive any Shares under those cancelled units.

4. Stockholder Rights and Dividend Equivalents

(a) The holder of this Award shall not have any stockholder rights, including voting or dividend rights, with respect to the Shares subject to the Award until the Participant becomes the record holder of those Shares following their actual issuance.

(b) Notwithstanding the foregoing, should any dividend or other distribution payable other than in shares of Common Stock, whether regular or extraordinary, be declared and paid on the outstanding Common Stock while one or more Shares remain subject to this Award (i.e., those Shares are not otherwise issued and outstanding for purposes of entitlement to the dividend or distribution), then a special book account shall be established for the Participant and credited with a phantom dividend equivalent to the actual dividend or distribution which would have been paid on those Shares had they been issued and outstanding and entitled to that dividend or distribution. As the Shares subsequently vest hereunder, the phantom dividend equivalents credited to those Shares in the book account shall be distributed to the Participant (in cash or such other form as the Plan Administrator may deem appropriate in its sole discretion) concurrently with the issuance of the vested Shares to which those phantom dividend equivalents relate.

5. Special Vesting Acceleration.

(a) Should a Change in Control or Hostile Take-Over occur during the Participant’s period of service as a Board member, then the Restricted Stock Units at the time subject to this Award will vest immediately prior to (i) the closing of such Change in Control or (ii) the effective date of such Hostile Take-Over. The Shares subject to those vested units will be issued immediately upon such vesting (or otherwise converted into the right to receive the same consideration per share of Common Stock payable to the other stockholders of the Corporation in consummation of the Change in Control transaction).

2

(b) Should the Participant cease service as a Board member by reason of death or Permanent Disability, then the Restricted Stock Units at the time subject to this Award will vest immediately, and the Shares subject to those vested units will be issued on such vesting date or within thirty (30) days following such vesting date.

(c) This Agreement shall not in any way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

6. Adjustment in Shares. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation’s receipt of consideration or should any spin-off of one or more Subsidiaries result in a substantial reduction in the Fair Market Value per share of the outstanding Common Stock, appropriate adjustments shall be made to the total number and/or class of securities issuable pursuant to this Award in order to reflect such change and thereby preclude a dilution or enlargement of benefits hereunder.

7. Issuance of Shares of Common Stock. On the applicable date on which the Shares vest in accordance with the terms of this Agreement or within thirty (30) days following such vesting date, the Corporation shall issue to or on behalf of the Participant a certificate (which may be in electronic form) for the shares of Common Stock which vest on that date and shall concurrently distribute to the Participant any phantom dividend equivalents with respect to those Shares. In no event, however, shall such issuance occur later than the later of (i) the end of the calendar year in which the applicable vesting date occurs or (ii) the fifteenth (15th) day of the third (3rd) calendar month following such vesting date.

8. Compliance with Laws and Regulations. The issuance of shares of Common Stock pursuant to the Award shall be subject to compliance by the Corporation and the Participant with all applicable requirements of law relating thereto and with all applicable regulations of any stock exchange on which the Common Stock may be listed for trading at the time of such issuance.

9. Notices. Any notice required to be given or delivered to the Corporation under the terms of this Agreement shall be in writing and addressed to the Corporation at its principal corporate offices. Any notice required to be given or delivered to the Participant shall be in writing and addressed to the Participant at the address indicated below the Participant’s signature line on this Agreement. All notices shall be deemed effective upon personal delivery or upon deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified.

11. Governing Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the State of Delaware without resort to that State’s conflict-of-laws rules.

12. Construction. This Agreement and the Award evidenced hereby are made and granted pursuant to the Plan and are in all respects limited by and subject to the terms of the Plan. This Agreement shall be construed in conformity with the terms of the Plan.

13. No Impairment of Rights. Nothing in this Agreement shall interfere with or otherwise restrict in any way the rights of the Corporation and the Corporation’s stockholders to remove the Participant from the Board at any time in accordance with the provisions of applicable law.
