                        PROGENICS PHARMACEUTICALS, INC.
                           INDEMNIFICATION AGREEMENT
     This Agreement, made and entered into as of this 1st day of June, 1995 
("Agreement"), by and between Progenics Pharmaceuticals, Inc., a Delaware 
corporation (the "Corporation"), and ▇▇▇▇ ▇. ▇▇▇▇▇▇, M.D.,Ph.D. (the 
"Indemnitee"):
     WHEREAS, recently highly competent persons have become more reluctant to 
serve publicly-held corporations as directors, officers, or in other 
capacities, unless they are provided with better protection from the risk of 
claims and actions against them arising out of their service to and 
activities on behalf of such corporation; and 
     WHEREAS, the current impracticability of obtaining adequate insurance and 
the uncertainties related to indemnification have increased the difficulty of
attracting and retaining such persons; and
     WHEREAS, the Board of Directors of the Corporation (the "Board") has 
determined that the inability to attract and retain such persons is 
detrimental to the best interests of the Corporation's stockholders and that 
such persons should be assured that they will have better protection in the 
future; and
     WHEREAS, it is reasonable, prudent and necessary for the Corporation to 
obligate itself contractually to indemnify such persons to the fullest extent 
permitted by applicable law so that such persons will serve or continue to 
serve the Corporation free from undue concern that they will not be 
adequately indemnified; and
     WHEREAS, this Agreement is a supplement to and in furtherance of Article 
XII of the By-laws of the Corporation, any rights granted under the 
Certificate of Incorporation of the Corporation and any resolutions adopted 
pursuant thereto and shall neither be deemed to be a substitute therefor nor 
to diminish or abrogate any rights of Indemnitee thereunder; and
    WHEREAS, Indemnitee is willing to serve, continue to serve and to take on 
additional service for or on behalf of the Corporation on the condition that 
he be indemnified according to the terms of this Agreement;
    NOW, THEREFORE, in consideration of the premises and the covenants 
contained herein, the Corporation and Indemnitee do hereby covenant and agree 
as follows:

response to any similar item on any similar schedule or form) promulgated 
under the Securities Exchange Act of 1934, as amended (the "Act"), whether or 
not the Corporation is then subject to such reporting requirement; provided, 
however, that, without limitation, such a Change in Control shall be deemed 
to have occurred if after the Effective Date (i) any "person" (as such term 
is used in Sections 13(d) and 14(d) of the Act) is or becomes the "beneficial

reason to constitute at least a majority of the Board.
     (b) "Corporate Status" means the status of a person who is or was a

threatened to be made, a party to any threatened, pending or completed 
Proceeding, other than a Proceeding by or in the right of the Corporation. 
Pursuant to this Section, Indemnitee shall be indemnified against Expenses, 
judgments, penalties, fines and amounts paid in settlement actually and

had no reasonable cause to believe his conduct was unlawful.
     Section 5.  PROCEEDINGS BY OR IN THE RIGHT OF THE CORPORATION.

favor. Pursuant to this Section, Indemnitee shall be indemnified against 
Expenses, judgments, penalties, fines and amounts paid in settlement, 
actually and reasonably incurred by him or on his behalf in connection with

Notwithstanding the foregoing, no indemnification against such Expenses shall 
be made in respect of any claim, issue or matter in any such Proceeding as to 
which Indemnitee shall have been adjudged to be liable to the Corporation if 
applicable law prohibits such indemnification unless the Court of Chancery of 
the State of Delaware, or the court in which such Proceeding shall have been 
brought or is pending, shall determine that indemnification against Expenses 
may nevertheless be made by the Corporation.
     Section 6.  INDEMNIFICATION FOR EXPENSES OF A PARTY WHO IS WHOLLY OR 
PARTLY SUCCESSFUL.  Notwithstanding any other provision of this Agreement, to 
the extent that Indemnitee is, by reason of his Corporate Status, a party to 
and is successful, on the merits or otherwise, in any Proceeding, he shall be 
indemnified against all Expenses actually and reasonably incurred by him or 
on his behalf in connection therewith. If Indemnitee is not wholly successful 
in such Proceeding but is successful, on the merits or otherwise, as to one 
or more but less than all claims, issues or matters in such Proceeding, the 
Corporation shall indemnify Indemnitee against all Expenses actually and 
reasonably incurred by him or on his behalf in connection with each 
successfully resolved claim, issue or matter. For the purposes of this 
Section and without limiting the foregoing, the termination of any claim, 
issue or matter in any such Proceeding by dismissal, with or without 
prejudice, shall be deemed to be a successful result as to such claim, issue 
or matter.
     Section 7.  INDEMNIFICATION FOR EXPENSES OF A WITNESS.  Notwithstanding

▇▇▇▇ ▇. ▇▇▇▇▇▇, M.D.,Ph.D.
     Section 8.  ADVANCEMENT OF EXPENSES.  The Corporation shall advance all 
Expenses incurred by or on behalf of Indemnitee in connection with any 
Proceeding within twenty (20) days after the receipt by the Corporation of a 
statement or statements from Indemnitee requesting such advance or advances 
from time to time, whether prior to or after final disposition of such 
Proceeding. Such statement or statements shall reasonably evidence the 
Expenses incurred by Indemnitee and shall include or be preceded or 
accompanied by an undertaking by or on behalf of Indemnitee to repay any 
Expenses advanced if it shall ultimately be determined that Indemnitee is not 
entitled to be indemnified against such Expenses.
     Section 9.  PROCEDURE FOR DETERMINATION OF ENTITLEMENT TO INDEMNIFICATION.
     (a) To obtain indemnification under this Agreement in connection with 
any Proceeding, and for the duration thereof, Indemnitee shall submit to the 
Corporation a written request, including therein or therewith such 
documentation and information as is reasonably available to Indemnitee and is 
reasonably necessary to determine whether and to what extent Indemnitee is 
entitled to indemnification. The Secretary of the Corporation shall, promptly 
upon receipt of any such request for indemnification, advise the Board in 
writing that Indemnitee has requested indemnification.
     (b) Upon written request by Indemnitee for indemnification pursuant to 
Section 9(a) hereof, a determination, if required by applicable law, with 
respect to Indemnitee's entitlement thereto shall be made in such case: (i) 
if a Change in Control shall have occurred, by Independent Counsel (unless 
Indemnitee shall request that such determination be made by the Board or the 
stockholders, in which case in the manner provided for in clauses (ii) or 
(iii) of this Section 9(b) in a written opinion to the Board, a copy of which 
shall be delivered to Indemnitee); (ii) if a Change of Control shall not have 
occurred, (A) by the Board by a majority vote of a quorum consisting of 
Disinterested Directors, or (B) if a quorum of the Board consisting of 
Disinterested Directors is not obtainable, or even if such quorum is 
obtainable, if such quorum of Disinterested Directors so directs, either (x) 
by Independent Counsel in a written opinion to the Board, a copy of which 
shall be delivered to Indemnitee, or (y) by the stockholders of the 
Corporation, as determined by such quorum of Disinterested Directors, or a 
quorum of the Board, as the case may be; or (iii) as provided in Section 
10(b) of this Agreement. If it is so determined that Indemnitee is entitled 
to indemnification, payment to Indemnitee shall be made within ten (10) days 
after such determination. Indemnitee shall cooperate with the person, persons 
or entity making such determination with respect to Indemnitee's entitlement 
to indemnification, including providing to such person, persons or entity 
upon reasonable advance request any documentation or information which is not 
privileged or otherwise protected from disclosure and which is reasonably 
available to Indemnitee and reasonably necessary to such determination. Any 
costs or expenses (including attorneys' fees and disbursements) incurred by 
Indemnitee in so cooperating with the person, persons or entity making such 
determination shall be borne by the Corporation (irrespective of the 
determination as to Indemnitee's entitlement to indemnification) and the 
Corporation hereby indemnifies and agrees to hold Indemnitee harmless 
therefrom.
     (c) If required, Independent Counsel shall be selected as follows: (i) 
if a Change of Control shall not have occurred, Independent Counsel shall be 
selected by the Board,
                                       4
Indemnification Agreement
▇▇▇▇ ▇. ▇▇▇▇▇▇, M.D.,Ph.D.
and the Corporation shall give written notice to Indemnitee advising him of 
the identity of Independent Counsel so selected; or (ii) if a Change of 
Control shall have occurred, Independent Counsel shall be selected by 
Indemnitee (unless Indemnitee shall request that such selection be made by 
the Board, in which event (i) shall apply), and Indemnitee shall give written 
notice to the Corporation advising it of the identity of Independent Counsel 
so selected. In either event, Indemnitee or the Corporation, as the case may 
be, may, within seven days after such written notice of selection shall have 
been given, deliver to the Corporation or to Indemnitee, as the case may be, 
a written objection to such selection. Such objection may be asserted only on 
the ground that Independent Counsel so selected does not meet the 
requirements of "Independent Counsel" as defined in Section 1 of this 
Agreement, and the objection shall set forth with particularity the factual 
basis of such assertion. If such written objection is made, Independent 
Counsel so selected may not serve as Independent Counsel unless and until a 
court has determined that such objection is without merit. If, within twenty 
(20) days after submission by Indemnitee of a written request for 
indemnification pursuant to Section 9(a) hereof, no Independent Counsel shall 
have been selected and not objected to, either the Corporation or Indemnitee 
may petition the Court of Chancery of the State of Delaware, or other court 
of competent jurisdiction, for resolution of any objection which shall have 
been made by the Corporation or Indemnitee to the other's selection of 
Independent Counsel and/or for the appointment as Independent Counsel of a 
person selected by such court or by such other person as such court shall 
designate, and the person with respect to whom an objection is so resolved or 
the person so appointed shall act as Independent Counsel under Section 9(b) 
hereof. The Corporation shall pay any and all reasonable fees and expenses of 
Independent Counsel incurred by such Independent Counsel in connection with 
its actions pursuant to this Agreement, and the Corporation shall pay all 
reasonable fees and expenses incident to the procedures of this Section 9(c), 
regardless of the manner in which such Independent Counsel was selected or 
appointed. Upon the due commencement date of any judicial proceeding or 
arbitration pursuant to Section 11(a)(iii) of this Agreement, Independent 
Counsel shall be discharged and relieved of any further responsibility in 
such capacity (subject to the applicable standards of professional conduct 
then prevailing).
     Section 10.  PRESUMPTIONS AND EFFECTS OF CERTAIN PROCEEDINGS.
     (a) If a Change of Control shall have occurred, in making a 
determination with respect to entitlement to indemnification hereunder, the 
person or persons or entity making such determination shall presume that 
Indemnitee is entitled to indemnification under this Agreement if Indemnitee 
has submitted a request for indemnification in accordance with Section 9(a) 
of this Agreement, and the Corporation shall have the burden of proof to 
overcome that presumption in connection with the making by any person, 
persons or entity of any determination contrary to that presumption.
     (b) If the person, persons or entity empowered or selected under Section 
9 of this Agreement to determine whether Indemnitee is entitled to 
indemnification shall not have made a determination within sixty (60) days 
after receipt by the Corporation of the request therefor, the requisite 
determination of entitlement to indemnification shall be deemed to have been 
made and Indemnitee shall be entitled to such indemnification, absent (i) a 
misstatement by
                                       5
Indemnification Agreement
▇▇▇▇ ▇. ▇▇▇▇▇▇, M.D.,Ph.D.
Indemnitee of a material fact, or an omission of a material fact necessary to 
make Indemnitee's statement not materially misleading, in connection with the 
request for indemnification, or (ii) prohibition of such indemnification 
under applicable law; provided, however, that such sixty (60) day period may 
be extended for a reasonable time, not to exceed an additional thirty (30) 
days, if the person, persons or entity making the determination with respect 
to entitlement to indemnification in good faith require(s) such additional 
time for the obtaining or evaluating of documentation and/or information 
relating thereto; and provided, further, that the foregoing provisions of 
this Section 10(b) shall not apply (i) if the determination of entitlement to 
indemnification is to be made by the stockholders pursuant to Section 9(b) of 
this Agreement and if (A) within fifteen (15) days after receipt by the 
Corporation of the request for such determination the Board has resolved to 
submit such determination to the stockholders for their consideration at an 
annual meeting thereof to be held within 75 days after such receipt and such 
determination is made thereat, or (B) a special meeting of stockholders is 
called within fifteen (15) days after such receipt for the purpose of making 
such determination, such meeting is held for such purpose within sixty (60) 
days after having been so called and such determination is made thereat, or 
(ii) if the determination of entitlement to indemnification is to be made by 
Independent Counsel pursuant to Section 9(b) of this Agreement.
     (c) The termination of any Proceeding or of any claim, issue or matter 
therein, by judgment, order, settlement or conviction, or upon a plea of NOLO 
CONTENDERE or its equivalent, shall not (except as otherwise expressly 
provided in this Agreement) of itself adversely affect the right of 
Indemnitee to indemnification or create a presumption that Indemnitee did not 
act in good faith and in a manner which he reasonably believed to be in or 
not opposed to the best interests of the Corporation or, with respect to any 
criminal Proceeding, that Indemnitee had reasonable cause to believe that his 
conduct was unlawful.
     Section 11.  REMEDIES OF INDEMNITEE.
     (a) In the event that (i) a determination is made pursuant to Section 9 
of this Agreement that Indemnitee is not entitled to indemnification under 
this Agreement, (ii) advancement of Expenses is not timely made pursuant to 
Section 8 of this Agreement, (iii) the determination of entitlement to 
indemnification is to be made by Independent Counsel pursuant to Section 9(b) 
of this Agreement and such determination shall not have been made and 
delivered in a written opinion within ninety (90) days after receipt by the 
Corporation of the request for indemnification, (iv) payment of 
indemnification is not made pursuant to Section 7 of this Agreement within 
ten (10) days after receipt by the Corporation of a written request therefor, 
or (v) payment of indemnification is not made within ten days after a 
determination has been made that Indemnitee is entitled to indemnification or 
such determination is deemed to have been made pursuant to Section 9 or 10 of 
this Agreement, Indemnitee shall be entitled to an adjudication in an 
appropriate court of the State of Delaware, or in any other court of 
competent jurisdiction, of his entitlement to such indemnification or 
advancement of Expenses. Alternatively, Indemnitee, at his option, may seek 
an award in arbitration to be conducted by a single arbitrator pursuant to 
the rules of the American Arbitration Association. Indemnitee shall commence 
such proceeding seeking an adjudication or an award in arbitration within one 
hundred eighty (180) days following the date on which Indemnitee first has 
the right to commence such proceeding pursuant
                                       6
Indemnification Agreement
▇▇▇▇ ▇. ▇▇▇▇▇▇, M.D.,Ph.D.
to this Section 1 l(a). The Corporation shall not oppose Indemnitee's right 
to seek any such adjudication or award in arbitration.
     (b) In the event that a determination shall have been made pursuant to 
Section 9 of this Agreement that Indemnitee is not entitled to 
indemnification, any judicial proceeding or arbitration commenced pursuant to 
this Section shall be conducted in all respects as a DE NOVO trial or 
arbitration on the merits and Indemnitee shall not be prejudiced by reason of 
that adverse determination. If a Change of Control shall have occurred in any 
judicial proceeding or arbitration commenced pursuant to this Section, the 
Corporation shall have the burden of proving that Indemnitee is not entitled 
to indemnification or advancement of Expenses, as the case may be.
     (c) If a determination shall have been made or deemed to have been made 
pursuant to Section 9 or 10 of this Agreement that Indemnitee is entitled to 
indemnification, the Corporation shall be bound by such determination in any 
judicial proceeding or arbitration commenced pursuant to this Section, absent 
(i) a misstatement by Indemnitee of a material fact, or an omission of a 
material fact necessary to make Indemnitee's statement not materially 
misleading, in connection with the request for indemnification, or (ii) 
prohibition of such indemnification under applicable law.
     (d) The Corporation shall be precluded from asserting in any judicial 
proceeding or arbitration commenced pursuant to this Section that the 
procedures and presumptions of this Agreement are not valid, binding and 
enforceable and shall stipulate in any such court or before any such 
arbitrator that the Corporation is bound by all the provisions of this 
Agreement.
     (e) In the event that Indemnitee, pursuant to this Section, seeks a 
judicial adjudication of, or an award in arbitration to enforce, his rights 
under, or to recover damages for breach of, this Agreement, Indemnitee shall 
be entitled to recover from the Corporation, and shall be indemnified by the 
Corporation against, any and all expenses (of the kinds described in the 
definition of Expenses) actually and reasonably incurred by him in such 
judicial adjudication or arbitration, but only if he prevails therein. If it 
shall be determined in such judicial adjudication or arbitration that 
Indemnitee is entitled to receive part but not all of the indemnification or 
advancement of expenses sought, the expenses incurred by Indemnitee in 
connection with such judicial adjudication or arbitration shall be 
appropriately prorated.
     Section 12.  NON-EXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE; SUBROGATION.
     (a) The rights of indemnification and to receive advancement of Expenses 
as provided by this Agreement shall not be deemed exclusive of any other 
rights to which Indemnitee may at any time be entitled under applicable law, 
the certificate of incorporation or by-laws of the Corporation, any 
agreement, a vote of stockholders or a resolution of directors, or otherwise. 
No amendment, alteration or repeal of this Agreement or any provision hereof 
shall be effective as to any Indemnitee with respect to any action taken or 
omitted by such Indemnitee in his Corporate Status prior to such amendment, 
alteration or repeal.
     (b) To the extent that the Corporation maintains an insurance policy or 
policies providing liability insurance for directors, officers, employees, 
agents or fiduciaries of the Corporation or of any other corporation, 
partnership, joint venture, trust, employee benefit plan or other enterprise 
which such person serves at the request of the Corporation, Indemnitee shall

to the maximum extent of the coverage available for any such director, 
officer, employee, agent or fiduciary under such policy or policies.
     (c) In the event of any payment under this Agreement, the Corporation 
shall be subrogated to the extent of such payment to all of the rights of 
recovery of Indemnitee, who shall execute all papers required and take all 
action necessary to secure such rights, including execution of such documents 
as are necessary to enable the Corporation to bring suit to enforce such 
rights.
     (d) The Corporation shall not be liable under this Agreement to make any 
payment of amounts otherwise indemnifiable hereunder if and to the extent

and terminate upon the later of: (a) ten (10) years after the date that 
Indemnitee shall have ceased to serve as a director, officer, employee, agent 
or fiduciary of the Corporation or of any other corporation, partnership, 
joint venture, trust, employee benefit plan or other enterprise which 
Indemnitee served at the request of the Corporation; or (b) the final 
termination of all pending Proceedings in respect of which Indemnitee is 
granted rights of indemnification or advancement of Expenses hereunder and or 
any proceeding commenced by Indemnitee pursuant to Section 11 of this 
Agreement. This Agreement shall be binding upon the Corporation and its 
successors and assigns and shall inure to the benefit of Indemnitee and his 
heirs, executors and administrators.

Agreement shall be held to be invalid, illegal or unenforceable for any 
reason whatsoever: (a) the validity, legality and enforceability of the 
remaining provisions of this Agreement (including, without limitation, each 
portion of any Section of this Agreement containing any such provision held 
to be invalid, illegal or unenforceable, that is not itself invalid, illegal 
or unenforceable) shall not in any way be affected or impaired thereby; and 
(b) to the fullest extent possible, the provisions of this Agreement 
(including, without limitation, each portion of any Section of this Agreement 
containing any such provision held to be invalid, illegal or unenforceable, 
that is not itself invalid, illegal or unenforceable) shall be construed so 
as to give effect to the intent manifested by the provision held invalid, 
illegal or unenforceable.
     Section 15.  EXCEPTION TO RIGHT OF INDEMNIFICATION OR ADVANCEMENT OF 
EXPENSES.  Except as provided in Section 11(e), Indemnitee shall not be 
entitled to indemnification or advancement of Expenses under this Agreement 
with respect to any Proceeding, or any claim therein, brought or made by him 
against the Corporation. For the purposes of this Section 15, a Proceeding in 
the right of the Corporation shall not be deemed to constitute a Proceeding 
brought or made by the Corporation.

one or more counterparts, each of which shall for all purposes be deemed to 
be an original but all of which together shall constitute one and the same 
Agreement. Only one such counterpart signed by the party against whom
