     5.3 Severability.
         ------------

          (a) If any provision of this Agreement shall be held by a court of
competent jurisdiction to be excessively broad as to duration, activity or
subject, it shall be deemed to extend only over the maximum duration, activity
and/or subject as to which such provision shall be valid and enforceable under
applicable law. If any provision shall, for any reason, be held by a court of
competent jurisdiction to be invalid, illegal or unenforceable, such invalidity,
illegality or unenforceability shall not affect any other provision of this
Agreement, but this Agreement shall be construed as if such invalid, illegal or
unenforceable provision had never been contained herein. Such court shall have
the authority to modify or replace the invalid or unenforceable term or
provision with a valid and enforceable term or provision which most accurately
represents the parties' intention with respect to the invalid or unenforceable
term or provision.

          (b) The parties intend that the covenants contained in Section 3 above
shall be construed as a series of separate covenants, one for each geographical
unit specified. Except for geographical coverage, each such separate covenant
shall be deemed identical in terms to the covenant contained in Section 3 above.
If, in any judicial proceeding, a court shall refuse to enforce any of the
separate covenants deemed included in this Agreement, then the unenforceable
covenant shall be deemed eliminated from these provisions for the purpose of
those proceedings to the extent necessary to permit the remaining separate
covenants to be enforced.

         --------------------
with, and governed in all respects by, the laws of the State of Washington

assert (by way of motion, as a defense or otherwise), in any such legal
proceeding commenced in any state or federal court located in the County of King
in the State of Washington, any claim that such party is not subject personally
to the jurisdiction of such court, that such legal proceeding has been brought
in an inconvenient forum, that the venue of such proceeding is improper or that
this Agreement or the subject matter of this Agreement may not be enforced in or
by such court.

delivered by the party to be charged; and any such waiver shall not be

Term shall not operate to relieve Employee of any obligation or liability
arising from any prior breach by Employee of any provision of the Agreement. The

                                      LEASE

     THIS FIRST AMENDMENT TO LEASE ("Amendment") dated April 11, 2001, by and
between CarrAmerica Realty Corporation, a Maryland corporation, as Landlord, and
ICOS Corporation, a Delaware corporation, as Tenant,

                              W I T N E S S E T H:

     WHEREAS, the parties entered into a written Lease dated as of January 7,
1999, with respect to 89,786 rentable square feet located in Building D, Canyon
Park East, Bothell, Washington (the "Premises"). The Premises are located on
Land legally described on Exhibit A hereto; and

     WHEREAS, the parties desire to modify and amend the Lease in the
particulars set forth herein;

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which the parties mutually acknowledge, the parties agree as
follows:

     1. Extension of Term. The parties mutually agree to extend the initial Term
of the Lease by five (5) years. The initial Term shall terminate January 31,
2009. The following shall be added at the end of Section 12 of the Schedule to
the Lease:

                           Square                         Annual                Monthly

</TABLE>

     2. Extension Option. The first sentence of Addendum 1 of the Lease shall be
revised to provide as follows: "Subject to Section B, below, Tenant may at its
option extend the Term of this Lease for two (2) successive periods of five (5)
years each." The effect of the foregoing change is that following the expiration
of the initial Term, as the same has been extended pursuant to this Amendment,
Tenant shall have two (2) additional options to extend the term of the Lease (as
opposed to three (3) additional options), in accordance with the remaining terms
and conditions of Addendum 1 to the Lease.

                                       -1-

     3. Construction of Improvements to Premises. Tenant shall improve the
Premises in accordance with plans and specifications approved by Landlord (the
"Plans"), which approval shall not be unreasonably withheld (such improvements
are referred to herein as the " Improvements"). Tenant shall perform the
Improvements at its own cost, subject to the Landlord's Contribution
(hereinafter defined). Tenant shall cause the Plans to be prepared, at Tenant's
cost, by a registered professional architect, and mechanical and electrical
engineer(s). Such engineer(s) shall be approved in advance by Landlord. Prior to
the close of business on April 6, 2001, Tenant shall furnish the initial draft
of the Plans to Landlord for its review and approval. Landlord shall within two
(2) weeks after receipt either provide comments to such Plans or approve the
same. Landlord shall be deemed to have approved such Plans if it does not timely
provide comments on such Plans. If Landlord provides Tenant with comments to the
initial draft of the Plans, Tenant shall provide revised Plans to Landlord
incorporating Landlord's comments within one week after receipt of Landlord's
comments. Landlord shall within one week after receipt then either provide
comments to such revised Plans or approve such Plans. Landlord shall be deemed
to have approved such revised Plans if Landlord does not timely provide comments
on such Plans. The process described above shall be repeated, if necessary,
until the Plans have been finally approved by Landlord. The Improvements shall
be performed by a contractor reasonably acceptable to Landlord (the
"Contractor"). Tenant hereby agrees that the Plans for the Improvements shall
comply with all applicable Governmental Requirements. Landlord's approval of any
of the Plans (or any modifications or changes thereto) shall not impose upon
Landlord or its agents or representatives any obligation with respect to the
design of the Improvements or the compliance of such Improvements or the Plans
with applicable Governmental Requirements. Tenant shall permit Landlord to
observe and monitor all Improvements.

          (a) Change Orders. If Tenant shall require improvements ("Change
Orders") to the Premises in addition to or substitution for the Improvements,
Tenant shall deliver to Landlord for its approval, which approval will not be
unreasonably withheld or delayed, plans and specifications for such Change
Orders. Landlord shall within one week after receipt of such initial draft of
plans and specifications for the Change Orders (the "Change Order Plans") either
provide comments to such Change Order Plans or approve the same, and Landlord's
failure to respond within one week after receipt of such initial draft shall be
deemed approval. If Landlord provides Tenant with comments to the initial draft
of the Change Order Plans, Tenant shall provide revised Change Order Plans to
Landlord incorporating Landlord's comments within one week after receipt of
Landlord's comments. Landlord shall then either provide comments to such revised
Change Order Plans or approve such Change Order Plans, and Landlord's failure to
respond within one week after receipt of such revised Change Order Plans shall
be deemed approval. The process described in the previous sentence shall be
repeated, if necessary, until the Change Order Plans have been finally approved
by Landlord. Tenant shall pay for all preparations and revisions of the Change
Order Plans and the construction of all Change Orders.

                                       -2-

          (b) Landlord's Contribution. Landlord shall contribute Four Hundred
Fifty Thousand Dollars ($450,000.00) ("Landlord's Contribution") toward the
costs incurred for the Improvements, including, without limitation, the costs
incurred by Tenant in connection with any necessary demolition of the Premises
and the preparation of the Plans, and any Change Orders. Landlord has no
obligation to pay for costs of the Improvements or Change Orders in excess of
Landlord's Contribution, notwithstanding any other provision hereof. Upon
written request of Tenant (not more frequently than twice each month), Landlord
shall pay all or any portion of the Landlord's Contribution to Tenant, within
thirty (30) days after receipt of (i) invoices, (ii) evidence satisfactory to
Landlord that the work covered by such invoices has been completed in a
satisfactory manner, (iii) all necessary lien waivers and sworn affidavits, (iv)
marked reproducible copies of the originally approved Plans showing all
substantial changes made in constructing the Improvements during such period
from the Plans as originally approved, (v) all close-out documentation set forth
in Landlord's "Policies, Rules and Procedures for Construction Projects" in
effect at the execution of the Lease, and (vi) such other documentation as
Landlord may reasonably require under the circumstances. Tenant shall request
payment, in accordance with the requirements of the preceding sentence, of the
entire Landlord's Contribution no later than December 31, 2001. Tenant shall
deliver reproducible as-built Plans to Landlord at the conclusion of the
Improvements. Tenant's construction of the Improvements shall otherwise comply
with Section 5A of the Lease.

     4. No Other Modifications. Except as set forth herein, the parties' Lease
shall remain unmodified and shall continue in full force and effect.

     IN WITNESS WHEREOF, the parties have executed this First Amendment to
Lease.
