2000 LONG-TERM INCENTIVE PLAN</B>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;THIS AGREEMENT, made as of the date on the <I>Notice of Grant of Stock
Options</I>, by and between Regeneron Pharmaceuticals, Inc., a New York corporation
(the &#147;Company&#148;), and the employee named on the <I>Notice of Grant of Stock Options</I>
(the &#147;Grantee&#148;);


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS, the Grantee is an employee of the Company and the Company desires
to afford the Grantee the opportunity to acquire or enlarge the Grantee&#146;s stock
ownership in the Company so that the Grantee may have a direct proprietary
interest in the Company&#146;s success; and


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS, the Committee administering the 2000 Long-Term Incentive Plan
(the &#147;Plan&#148;) has granted (as of the effective date of grant specified in the
<I>Notice of Grant of Stock Options</I>) to the Grantee a Stock Option to purchase the
number of shares of the Company&#146;s Common Stock ($.001 par value) (the &#147;Common
Stock&#148;) as set forth in the <I>Notice of Grant of Stock Options</I>.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NOW, THEREFORE, in consideration of the covenants and agreements herein
contained, the parties agree as follows:


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>1.&nbsp;Grant of Award. </B>Pursuant to Section&nbsp;7 of the Plan, the Company grants
to the Grantee, subject to the terms and conditions of the Plan and subject
further to the terms and conditions set forth here, the option to purchase from
the Company all or any part of an aggregate of shares of Common Stock at the
purchase price per share (the &#147;Option&#148;) as shown on the <I>Notice of Grant of
Stock Options</I>. &#091;The Option is intended to be an Incentive Stock Option under
Section&nbsp;422 of the Internal Revenue Code of 1986, as amended (the &#147;Code&#148;).
Notwithstanding the foregoing, the Option will not qualify as an Incentive
Stock Option, among other events, (i)&nbsp;if the Grantee disposes of the Common
Stock acquired pursuant to the Option at any time during the two year period
following the date of this Agreement or the one year period following the date
on which the Option is exercised, or (ii)&nbsp;if the Grantee is not employed by the
Company or a subsidiary of the Company within the meaning of Section&nbsp;424 of the
Code (a &#147;Subsidiary&#148;) at all times during the period beginning on the date of
this Agreement and ending on the day three months before the date of exercise
of the Option, or (iii)&nbsp;to the extent the aggregate fair market value
(determined as of the time the Option is granted) of the stock subject to
Incentive Stock Options which become exercisable for the first time in any
calendar year exceeds $100,000. To the extent that the Option does not qualify
as an Incentive Stock Option, it shall constitute a separate Non Qualified
Stock Option.&#093;<SUP>1</SUP> &#091;No part of the Option granted hereby is intended to qualify
as an Incentive Stock Option under Section&nbsp;422 of the Internal Revenue Code of
1986, as amended (the &#147;Code&#148;).&#093;<SUP>2</SUP>.

as provided on the <I>Notice of Grant of Stock Options </I>and subject to the terms
and conditions of the Plan, including without limitation, Section&nbsp;7(c)(1) &#038;
(2), the Option may thereafter be exercised by the Grantee, in whole or in
part, at any time or from time to time prior to the expiration of the Option in
accordance with the requirements set forth in Section&nbsp;7(c)(3) of the Plan,
including, without limitation, the filing of such written form of exercise

all Subsidiaries shall be referred to herein as the &#147;Employer&#148; and no
termination of employment or service shall be deemed to take place unless the

Option&#148;) on the date of exercise for a number of shares equal to the number of
shares surrendered by the Grantee upon exercise, subject to the availability of
shares of Common Stock under the Plan at the time of such exercise. Such
Reload Option shall be granted at an exercise price equal to the Fair Market
Value (as defined in the Plan) of a share of Common Stock on the date of grant,
shall expire on the date on which the original Option would have expired, and
shall be fully vested; provided, however, that the Reload Option may not be
exercised until the date that is six months after the date of grant. The
Reload Option shall otherwise be subject to the same terms and conditions as
the original Option; provided, however, that the exercise of the Reload Option
shall not entitle the Grantee to any further Reload grant.&#093;<SUP>3</SUP>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;Notwithstanding anything herein (except the following sentence) or in
the <I>Notice of Grant of Stock Options </I>to the contrary, the Option shall be fully
vested if the Grantee&#146;s employment with the Employer (or serve as a member of
the Board of Directors, as the case may be) is terminated on or within two
years after the occurrence of a Change in Control by the Employer (other than
for Cause) or by the Grantee for Good Reason. Except as otherwise provided in
any employment agreement, consulting agreement, change in control agreement or
similar agreement in effect between the Employer and the Grantee on the date of

the provision in the foregoing sentence, similar provisions in other stock
option or restricted stock grants, and other payments and benefits payable to
the Grantee upon termination of employment (collectively, the &#147;Company
Payments&#148;) would result in the Grantee being subject to excise tax payable
under Internal Revenue Code Section&nbsp;4999 (the Excise Tax&#148;), the amount of any
Company Payments shall be automatically reduced to an amount one dollar less

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>4.&nbsp;Restrictions on Transfer of Option. </B>The Option granted hereby shall
not be transferable other than by will or by the laws of descent and
distribution. During the lifetime of the Grantee, this Option shall be
exercisable only by the Grantee. In addition, except as otherwise provided in
this Agreement, the Option shall not be assigned, negotiated, pledged or
hypothecated in any way (whether by operation of law or otherwise), and the
Option shall not be subject to execution, attachment or similar process. Upon
any other attempt to transfer, assign, negotiate, pledge or hypothecate the
Option, or in the event of any levy upon the option by reason of any execution,
attachment, or similar process contrary to the provisions hereof, the Option
shall immediately become null and void. Notwithstanding the foregoing
provisions of this Section&nbsp;4, subject to the approval of the Committee in its
sole and absolute discretion and to any conditions that the Committee may
prescribe, the Grantee may, upon providing written notice to the Company, elect
to transfer the Option to members of his or her immediate family, including,
but not limited to, children, grandchildren and spouse or to trusts for the
benefit of such immediate family members or to partnerships in which such
family members are the only partners; provided, however, that no such transfer
may be made in exchange for consideration.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>5.&nbsp;Rights of a Stockholder. </B>The Grantee shall have no rights as a
stockholder with respect to any shares of Common Stock subject to this Option
prior to the date of issuance to the Grantee of a certificate or certificates
for such shares. No adjustment shall be made for dividends in cash or other
property, distributions, or other rights with respect to such shares for which
the record date is prior to the date upon which the Grantee shall become the
holder of record therefor.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>6.&nbsp;Compliance with Law and Regulations. </B>This award and any obligation of
the Company hereunder shall be subject to all applicable federal, state and
local laws, rules and regulations and to such approvals by any government or
regulatory agency as may be required. The Company shall be under no obligation
to effect the registration pursuant to federal securities laws of any interests
in the Plan or any shares of Common Stock to be issued hereunder or to effect
similar compliance under any state laws. The Company shall not be obligated to
cause to be issued or delivered any certificates evidencing shares of Common
Stock pursuant to this Agreement unless and until the Company is advised by its
counsel that the issuance and delivery of such certificates is in compliance
with all applicable laws, regulations of governmental authority and the
requirements of any securities exchange on which shares of Common Stock are
traded. The Committee may require, as a condition of the issuance and delivery
of certificates evidencing shares of Common Stock pursuant to the terms hereof,
that the recipient of such shares make such agreements and representations, and
that such certificates bear such legends, as the Committee, in its sole
discretion, deems necessary or desirable. Except to the extent preempted by
any applicable federal law, this Agreement shall be construed and administered
in accordance with the laws of the State of New York without reference to its
principles of conflicts of law.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>7.&nbsp;Grantee Bound by Plan. </B>The Grantee acknowledges receipt of a copy of
the Plan and agrees to be bound by all the terms and provisions thereof. The
Plan is incorporated herein by reference, and any capitalized term used but not
defined herein shall have the same meaning as in the Plan. To the extent that
this Agreement is silent with respect to, or in any way inconsistent with, the
terms of the Plan, the provisions of the Plan shall govern and this Agreement
shall be deemed to be modified accordingly.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>8.&nbsp;Notices. </B>Any notice or communication given hereunder shall be in
writing and shall be deemed given when delivered in person, or by United States
mail, at the following addresses: (i)&nbsp;if to the Employer, to: Regeneron
Pharmaceuticals, Inc., 777 Old Saw Mill River Road, Tarrytown, NY 10591,
Attention: Secretary, and (ii)&nbsp;if to the Grantee, to: the Grantee at

10591, or, if the Grantee has terminated employment, to the last address for
the Grantee indicated in the records of the Employer, or such other address as
the relevant party shall specify at any time hereafter in accordance with this
Section&nbsp;8.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>9.&nbsp;No Obligation to Continue Employment. </B>This Agreement does not
guarantee that the Employer will employ the Grantee for any specified time
period, nor does it modify in any respect the Grantee&#146;s employment or
compensation.

2000 LONG-TERM INCENTIVE PLAN</B>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;THIS AGREEMENT, made as of the date on the <I>Notice of Grant of Stock
Options</I>, by and between Regeneron Pharmaceuticals, Inc., a New York corporation
(the &#147;Company&#148;), and the employee named on the <I>Notice of Grant of Stock Options</I>
(the &#147;Grantee&#148;);


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS, the Grantee is an employee of the Company and the Company desires
to afford the Grantee the opportunity to acquire or enlarge the Grantee&#146;s stock
ownership in the Company so that the Grantee may have a direct proprietary
interest in the Company&#146;s success; and


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS, the Committee administering the 2000 Long-Term Incentive Plan
(the &#147;Plan&#148;) has granted (as of the effective date of grant specified in the
<I>Notice of Grant of Stock Options</I>) to the Grantee a Stock Option to purchase the
number of shares of the Company&#146;s Common Stock ($.001 par value) (the &#147;Common
Stock&#148;) as set forth in the <I>Notice of Grant of Stock Options</I>.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NOW, THEREFORE, in consideration of the covenants and agreements herein
contained, the parties agree as follows:


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>1.&nbsp;Grant of Award. </B>Pursuant to Section&nbsp;7 of the Plan, the Company grants
to the Grantee, subject to the terms and conditions of the Plan and subject
further to the terms and conditions set forth here, the option to purchase from
the Company all or any part of an aggregate of shares of Common Stock at the
purchase price per share (the &#147;Option&#148;) as shown on the <I>Notice of Grant of
Stock Options</I>. &#091;The Option is intended to be an Incentive Stock Option under
Section&nbsp;422 of the Internal Revenue Code of 1986, as amended (the &#147;Code&#148;).
Notwithstanding the foregoing, the Option will not qualify as an Incentive
Stock Option, among other events, (i)&nbsp;if the Grantee disposes of the Common
Stock acquired pursuant to the Option at any time during the two year period
following the date of this Agreement or the one year period following the date
on which the Option is exercised, or (ii)&nbsp;if the Grantee is not employed by the
Company or a subsidiary of the Company within the meaning of Section&nbsp;424 of the
Code (a &#147;Subsidiary&#148;) at all times during the period beginning on the date of
this Agreement and ending on the day three months before the date of exercise
of the Option, or (iii)&nbsp;to the extent the aggregate fair market value
(determined as of the time the Option is granted) of the stock subject to
Incentive Stock Options which become exercisable for the first time in any
calendar year exceeds $100,000. To the extent that the Option does not qualify
as an Incentive Stock Option, it shall constitute a separate Non Qualified
Stock Option.&#093;<SUP>4</SUP> &#091;No part of the Option granted hereby is intended to qualify
as an Incentive Stock Option under Section&nbsp;422 of the Internal Revenue Code of
1986, as amended (the &#147;Code&#148;).&#093;<SUP>5</SUP>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>2.&nbsp;Vesting. </B>(a)&nbsp;The Option is exercisable in installments as provided on
the <I>Notice of Grant of Stock Options</I>. To the extent that the Option has become
exercisable with respect to the number of shares of Common Stock as provided on
the <I>Notice of Grant of Stock Options </I>and subject to the terms and conditions of
the Plan, including without limitation, Section&nbsp;7(c)(1) &#038; (2), the Option may
thereafter be exercised by the Grantee, in whole or in part, at any time or
from time to time prior to the expiration of the Option in accordance with the
requirements set forth in Section&nbsp;7(c)(3) of the Plan, including, without
limitation, the filing of such written form of exercise notice as may be
promulgated by the Committee, and in accordance with applicable tax and other
laws. The Company shall have the right to require the Grantee

tax requirements related thereto.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;The <I>Notice of Grant of Stock Options </I>indicates each date upon which
the Grantee shall be entitled to exercise the Option with respect to the
additional number of shares of Common Stock granted as indicated provided that
the Grantee has not incurred a termination of employment or service with the
Company and all Subsidiaries (collectively, the Company and all Subsidiaries
shall be referred to herein as the &#147;Employer&#148; and no termination of employment
or service shall be deemed to take place unless the Grantee is no longer
employed by or providing service to the Employer) prior to such date. There
shall be no proportionate or partial vesting in the periods between the Full
Vest Dates specified in the <I>Notice of Grant of Stock Options </I>and all vesting
shall occur only on the Full Vest Dates. Except as otherwise provided in any
employment agreement, consulting agreement, change in control agreement or
similar agreement in effect between the Employer and the Grantee on the date
specified in the <I>Notice of Grant of Stock Options</I>, no vesting shall occur after
such date as the Grantee ceases to be employed by the Employer and all unvested
Options shall be forfeited at such time.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;Notwithstanding anything herein (except the following sentence) or
in the <I>Notice of Grant of Stock Options </I>to the contrary, the Option shall be
fully vested if the Grantee&#146;s employment with the Employer is terminated on or
within two years after the occurrence of a Change in Control by the Employer
(other than for Cause) or by the Grantee for Good Reason. Except as otherwise
provided in any employment agreement, consulting agreement, change in control
agreement or similar agreement in effect between the Employer and the Grantee
on the date of grant specified in the <I>Notice of Grant of Stock Options</I>, if the
application of the provision in the foregoing sentence, similar provisions in
other stock option or restricted stock grants, and other payments and benefits
payable to the Grantee upon termination of employment (collectively, the
&#147;Company Payments&#148;) would result in the Grantee being subject to the excise tax
payable under Internal Revenue Code Section&nbsp;4999 (the &#147;Excise Tax&#148;), the amount
of any Company Payments shall be automatically reduced to an amount one dollar
less than an amount that would subject the Grantee to the Excise Tax; provided,
however, that the reduction shall occur only if the reduced Company Payments
received by the Grantee (after taking into account further reductions for
applicable federal, state and local income, social security and other taxes)
would be greater than the unreduced Company Payments to be received by the
Grantee minus (i)&nbsp;the Excise Tax payable with respect to such Company Payments
and (ii)&nbsp;all applicable federal, state and local income, social security and
other taxes on such Company Payments. If the Company Payments are to be
reduced in accordance with the foregoing, the Company Payments shall be reduced
as mutually agreed between the Employer and the Grantee or, in the event the
parties cannot agree, in the following order (1)&nbsp;acceleration of vesting of any
option where the exercise price exceeds the fair market value of the underlying
shares at the time the acceleration would otherwise occur, (2)&nbsp;any lump sum
severance based on a multiple of base salary or bonus, (3)&nbsp;any other cash
amounts payable to the Grantee, (4)&nbsp;any benefits valued as parachute payments,
and (5)&nbsp;acceleration of vesting of any equity not covered by (1)&nbsp;above.

in the Plan, the Option shall expire on the Expiration Date shown on the <I>Notice
of Grant of Stock Options</I>. In the event of termination of employment or
service with the Employer, except as set forth in any employment agreement,
consulting agreement, change in control agreement or similar agreement in
effect between the Employer and the Grantee on the date of grant specified in
the <I>Notice of Grant of Stock Options</I>, the vested portion of the Option shall
expire on the earlier of (i)&nbsp;the Expiration Date, or (ii) (A)&nbsp;subject to (E)
below, three months after such termination if such termination is for any
reason other than death, retirement, or long-term disability, (B)&nbsp;two years
after such termination if such termination is due to the Grantee&#146;s retirement,
(C)&nbsp;one year after the termination if such termination is due to the Grantee&#146;s
death or long-term disability, (D)&nbsp;the occurrence of the Cause event if such
termination is for Cause or Cause existed at the time of such termination
(whether then known or later discovered) or (E)&nbsp;one year after such termination
if such termination is at any time within two years after the occurrence of a
Change in Control and is by the Employer without Cause or by the Grantee for
Good Reason.

there is an employment agreement, consulting agreement, change in control
agreement or similar agreement in effect between the Employer and the Grantee
on the date of grant specified in the <I>Notice of Grant of Stock Options </I>that
defines &#147;cause&#148; (or words of like import), as defined under such agreement.
For purposes of this Section&nbsp;3(b), no act, or failure to act, on a Grantee&#146;s
part shall be considered &#147;willful&#148; unless done, or omitted to be done, by the
Grantee in bad faith and without reasonable belief that his or her action or
omission was in the best interest of the Employer. Any determination of Cause
made prior to a Change in Control shall be made by the Committee in its sole
discretion.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;For purposes of this Agreement, &#147;Good Reason&#148; shall mean (i)&nbsp;in the
case where there is no employment agreement, consulting agreement, change in
control agreement or similar agreement in effect between the Employer and the
Grantee on the date of grant specified in the <I>Notice of Grant of Stock Options</I>
(or where there is such an agreement but it does not define &#147;good reason&#148; (or
words of like import)) a termination of employment by the Grantee within one
hundred twenty (120)&nbsp;days after the occurrence of one of the following events
after the occurrence of a Change in Control unless such events are fully
corrected in all material respects by the Employer within thirty (30)&nbsp;days
following written notification by the Grantee to the Employer that Grantee
intends to terminate his employment hereunder for one of the reasons set forth
below: (A) (1)&nbsp;any material diminution in the Grantee&#146;s duties and
responsibilities from that which exists immediately prior to a Change in
Control (except in each case in connection with the termination of the
Grantee&#146;s employment for Cause or as a result of the Grantee&#146;s death, or
temporarily as a result of the Grantee&#146;s illness or other absence), or (2)&nbsp;the
assignment to the Grantee of duties and responsibilities materially
inconsistent with the position held by the Grantee; (B)&nbsp;any material breach by
the Employer of any material provision of any written agreement with the
Grantee or failure to timely pay any compensation obligation to the Grantee;
(C)&nbsp;a reduction in the Grantee&#146;s annual base salary or target bonus opportunity
(if any) from that which exists immediately prior to a Change in Control; or
(D)&nbsp;if the Grantee is based at the Employer&#146;s principal executive office, any
relocation therefrom or, in any event, a relocation of the Grantee&#146;s primary
office of more than fifty (50)&nbsp;miles from the location immediately prior to a
Change in Control; or (ii)&nbsp;in the case where there is an employment agreement,
consulting agreement, change in control agreement or similar agreement in
effect between the Employer and the Grantee on the date of grant specified in
the <I>Notice of Grant of Stock Options </I>that defines &#147;good reason&#148; (or words of
like import), as defined under such agreement.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>4.&nbsp;Restrictions on Transfer of Option. </B>The Option granted hereby shall
not be transferable other than by will or by the laws of descent and
distribution. During the lifetime of the Grantee, this Option shall be
exercisable only by the Grantee. In addition, except as otherwise provided in
this Agreement, the Option shall not be assigned, negotiated, pledged or
hypothecated in any way (whether by operation of law or otherwise), and the
Option shall not be subject to execution, attachment or similar process. Upon
any other attempt to transfer, assign, negotiate, pledge or hypothecate the
Option, or in the event of any levy upon the option by reason of any execution,
attachment, or similar process contrary to the provisions hereof, the Option
shall immediately become null and void. Notwithstanding the foregoing
provisions of this Section&nbsp;4, subject to the approval of the Committee in its
sole and absolute discretion and to any conditions that the Committee may
prescribe, the Grantee may, upon providing written notice to the Company, elect
to transfer the Option to members of his or her immediate family, including,
but not limited to, children, grandchildren and spouse or to trusts for the
benefit of such immediate family members or to partnerships in which such
family members are the only partners; provided, however, that no such transfer
may be made in exchange for consideration.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>6.&nbsp;Compliance with Law and Regulations. </B>This award and any obligation of
the Company hereunder shall be subject to all applicable federal, state and

regulatory agency as may be required. The Company shall be under no obligation
to effect the registration pursuant to federal securities laws of any interests
in the Plan or any shares of Common Stock to be issued hereunder or to effect
similar compliance under any state laws. The Company shall not be obligated to
cause to be issued or delivered any certificates evidencing shares of Common
Stock pursuant to this Agreement unless and until the Company is advised by its
counsel that the issuance and delivery of such certificates is in compliance
with all applicable laws, regulations of governmental authority and the
requirements of any securities exchange on which shares of Common Stock are

principles of conflicts of law.

the Plan and agrees to be bound by all the terms and provisions thereof. The
Plan is incorporated herein by reference, and any capitalized term used but not
defined herein shall have the same meaning as in the Plan. To the extent that
this Agreement is silent with respect to, or in any way inconsistent with, the
terms of the Plan, the provisions of the Plan shall govern and this Agreement
shall be deemed to be modified accordingly.

the relevant party shall specify at any time hereafter in accordance with this
Section&nbsp;8.

guarantee that the Employer will employ the Grantee for any specified time

PURSUANT TO THE<BR>
2000 LONG-TERM INCENTIVE PLAN</B>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;THIS AGREEMENT, made as of the date on the <I>Notice of Grant of Restricted
Stock</I>, by and between Regeneron Pharmaceuticals, Inc., a New York corporation
(the &#147;Company&#148;), and the employee named on the <I>Notice of Grant of Restricted
Stock </I>(the &#147;Recipient&#148;);


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS, the Recipient is an employee of the Company and the Company
desires to afford the Recipient the opportunity to acquire or enlarge the
Recipient&#146;s stock ownership in the Company so that the Recipient may have a
direct proprietary interest in the Company&#146;s success; and


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS, the Committee administering the 2000 Long-Term Incentive Plan
(the &#147;Plan&#148;) has granted (as of the effective date of grant specified in the
<I>Notice of Grant of Restricted Stock</I>) to the Recipient the shares of Restricted
Stock as set forth in the <I>Notice of Grant of Restricted Stock</I>.

<P align="left" style="font-size: 10pt">NOW, THEREFORE, in consideration of the covenants and agreements herein
contained, the parties agree as follows:



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;Grant of Award. Pursuant to Section&nbsp;8 of the Plan, the Company grants
to the Recipient, subject to the terms and conditions of the Plan and subject
further to the terms and conditions set forth herein, the number of shares of
Restricted Stock as shown on the <I>Notice of Grant of Restricted Stock</I>. The
Participant&#146;s grant and record of Restricted Stock share ownership shall be
kept on the books of the Company until the restrictions on transfer have
lapsed. At the Recipient&#146;s request, vested shares may be evidenced by stock
certificates.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.&nbsp;Vesting. (a)&nbsp;The shares of Restricted Stock granted to the Recipient
shall vest in installments as provided in the <I>Notice of Grant of Restricted
Stock</I>. The vesting schedule in the <I>Notice of Grant of Restricted Stock</I>
indicates each date upon which the restrictions on transfer on the specified
number of shares of Restricted Stock shall lapse, entitling the Recipient to
freely transfer such shares, provided that the Recipient has not incurred a
termination of employment or service with the Company and all Subsidiaries
(collectively, the Company and its Subsidiaries shall be referred to herein as
the &#147;Employer&#148;). There shall be no proportionate or partial vesting in the
periods between the Full Vest Dates specified in the <I>Notice of Grant of
Restricted Stock </I>and all vesting shall occur only on the Full Vest Dates.
Except as set forth in the Plan or in any employment agreement, consulting
agreement, change in control agreement or similar agreement in effect between
the Employer and the Recipient on the date specified in the <I>Notice of Grant of
Restricted Stock</I>, no vesting shall occur after the termination of a Recipient&#146;s
employment or service with the Employer for any reason.

<P align="left" style="font-size: 10pt">(b)&nbsp;Notwithstanding anything herein (except the following sentence) or in the
<I>Notice of Grant of Restricted Stock </I>to the contrary, the Restricted Stock
granted to Recipient shall be fully vested if the Recipient&#146;s employment with
the Employer is terminated on or within two years after the occurrence of a
Change in Control by the Company (other than for Cause) or by the Recipient for
Good Reason. Except as otherwise provided in any employment agreement,
consulting agreement, change in control agreement or similar agreement in
effect between the Employer and the Recipient on the date of grant specified in
the <I>Notice of Grant of Restricted Stock</I>, if the application of the provision in
the foregoing sentence, similar provisions in other stock option or restricted
stock grants, and other payments and benefits payable to the Grantee upon
termination of employment (collectively, the &#147;Company Payments&#148;) would result
in the Recipient being subject to excise tax payable under Internal Revenue
Code Section&nbsp;4999 (the &#147;Excise Tax&#148;) , the amount of

<P align="left" style="font-size: 10pt">any Company Payments shall be automatically reduced to an amount one dollar
less than an amount that would subject the Recipient to the Excise Tax;
provided, however, that the reduction shall occur only if the reduced Company
Payments received by the Recipient (after taking into account further
reductions for applicable federal, state and local income, social security and
other taxes) would be greater than the unreduced Company Payments to be
received by the Recipient minus (i)&nbsp;the Excise Tax payable with respect to such
Company Payments and (ii)&nbsp;all applicable federal, state and local income,
social security and other taxes on such Company Payments. If the Company
Payments are to be reduced in accordance with the foregoing, the Company
Payments shall be reduced as mutually agreed between the Employer and the
Recipient or, in the event the parties cannot agree, in the following order (1)
acceleration of vesting of any option where the exercise price exceeds the fair
market value of the underlying shares at the time the acceleration would
otherwise occur, (2)&nbsp;any lump sum severance based on a multiple of base salary
or bonus, (3)&nbsp;any other cash amounts payable to the Recipient, (4)&nbsp;any benefits
valued as parachute payments, and (5)&nbsp;acceleration of vesting of any equity not
covered by (1)&nbsp;above.


<P align="left" style="font-size: 10pt">(c)&nbsp;For purposes of this Agreement, &#147;Cause&#148; shall mean (i)&nbsp;in the case where
there is no employment agreement, consulting agreement, change in control
agreement or similar agreement in effect between the Employer and the Recipient
on the date of grant specified in the <I>Notice of Grant of Restricted Stock </I>(or
where there is such an agreement but it does not define &#147;cause&#148; (or words of

substantially to perform his or her duties and obligations to the Employer,
including without limitation, repeated refusal to follow the reasonable
directions of the Employer, knowing violation of law in the course of
performance of the duties of the Recipient&#146;s employment with the Employer,
repeated absences from work without a reasonable excuse, and intoxication with
alcohol or illegal drugs while on the Employer&#146;s premises during regular
business hours (other than any such failure resulting from his or her
incapacity due to physical or mental illness); (B)&nbsp;fraud or material dishonesty
against the Employer; or (C)&nbsp;a conviction or plea of guilty or nolo contendere
to a felony or a crime involving material dishonesty or (ii)&nbsp;in the case where
there is an employment agreement, consulting agreement, change in control
agreement or similar agreement in effect between the Employer and the Recipient
on the date of grant specified on the <I>Notice of Grant of Restricted Stock </I>that
defines &#147;cause&#148; (or words of like import), as defined under such agreement.
For purposes of this Section&nbsp;3(c), no act, or failure to act, on a Recipient&#146;s
part shall be considered &#147;willful&#148; unless done, or omitted to be done, by the
Recipient in bad faith and without reasonable belief that his or her action or
omission was in the best interest of the Employer. Any determination of Cause
made prior to a Change in Control shall be made by the Committee in its sole
discretion.


<P align="left" style="font-size: 10pt">(d)&nbsp;For purposes of this Agreement, &#147;Good Reason&#148; shall mean (i)&nbsp;in the case

where there is such an agreement but it does not define &#147;good reason&#148; (or words

after the occurrence of a Change in Control unless such events are fully
corrected in all material respects by the Employer within thirty (30)&nbsp;days
following written notification by the Recipient to the Employer that Recipient
intends to terminate his employment hereunder for one of the reasons set forth
below: (A) (1)&nbsp;any material diminution in the Recipient&#146;s duties and

Control (except in each case in connection with the termination of the
Recipient&#146;s employment for Cause or as a result of the Recipient&#146;s death, or
temporarily as a result of the Recipient&#146;s illness or other absence), or (2)
the assignment to the Recipient of duties and responsibilities materially
inconsistent with the position held by the Recipient; (B)&nbsp;any material breach
by the Employer of any material provision of any written agreement with the
Recipient or failure to timely pay any compensation obligation to the

employment agreement, consulting agreement, change in control agreement or

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.&nbsp;Termination of Service. Subject to the terms of the Plan and Section
2(b), if the Recipient&#146;s employment or service with the Company is terminated
for any reason (other than as set forth in Section&nbsp;2(b)), the Recipient shall
forfeit any or all of the shares of Restricted Stock that have not vested in

Committee in its sole discretion.

transfer any Unvested Shares or other shares of Company Stock to the Recipient,

Securities Act (or any other federal or state statutes having similar
requirements as may be in effect at that time).

violation of the provisions of this Restricted Stock Agreement or the
Certificate of Incorporation or the by-laws of the Company, shall be valid, and

and in any event at the time the Recipient recognizes taxable income in respect

Section 83(b) of the Code in connection with such grant), an amount equal to
the federal, state and/or local taxes the Company determines it is required to

responsible for any tax liability that may arise as a result of the
transactions contemplated by this Restricted Stock Agreement.
