AMENDMENT NO. 1 TO RIGHTS AGREEMENT
Exhibit 4.1
THIS AMENDMENT NO. 1 TO RIGHTS AGREEMENT is entered into as of this 17th day of
January, 2007 by and between Nastech Pharmaceutical Company Inc. (the “Company”) and American Stock
Transfer & Trust Company (the “Rights Agent”).
RECITALS:
WHEREAS, the Company and the Rights Agent previously entered into that certain Rights
Agreement dated February 22, 2000 (the “Rights Agreement”) to provide for, among other things,
certain preferred share purchase rights of the Company’s stockholders; and
WHEREAS, the Company and the Rights Agent desire to amend the Rights Agreement to make it
clear, for avoidance of doubt, that a bona fide underwriter is excluded from the definition of an
“Acquiring Person” under the Rights Agreement.
NOW, THEREFORE, in consideration of the rights and obligations contained herein, and for other
good and valuable consideration, the adequacy of which is hereby acknowledged, the parties agree as
follows:
SECTION 1. Amendment to Rights Agreement. Paragraph (a) of Section 1 of the Rights
Agreement is hereby amended by adding the following at the end of such paragraph:
“For purposes of determining whether a person is an “Acquiring Person” under this
Rights Agreement, pursuant to Rule 13d-3(d)(4) under the Securities Exchange Act of 1934,
as amended, a person engaged in business as an underwriter of securities who acquires
securities through its participation in good faith in a firm commitment underwriting
registered under the Securities Act of 1933, as amended, shall not be deemed to be the
beneficial owner of such securities until the expiration of forty calendar days after the
date of such acquisition.”
SECTION 2. Entire Agreement. This Amendment constitutes the entire agreement of the
parties hereto with respect to the subject matter hereof and supersedes all prior agreements and
undertakings, both written and oral, between the Company and the Rights Agent with respect to the
subject matter hereof and thereof. Except as modified by this Amendment, the Rights Agreement
remains in full force and effect.
SECTION 3. Severability. If any term or other provision of this Amendment is invalid,
illegal or incapable of being enforced by any law or public policy, all other terms
and provisions of this Amendment shall nevertheless remain in full force and effect for so long as
the economic or legal substance of the transactions contemplated by this Amendment is not affected
in any manner materially adverse to either party hereto. Upon such determination that any term or
other provision is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Amendment so as to effect the original intent of the parties
as closely as possible in an acceptable manner in order that the transactions contemplated by this
Amendment are consummated as originally contemplated to the greatest extent possible.
SECTION 4. Counterparts. This Amendment shall not be effective or binding until such
time as it has been executed and delivered by all parties hereto. This Amendment may be executed
and delivered (including by facsimile transmission or portable document format (PDF)) in one or
more counterparts, and by the different parties hereto in separate counterparts, each of which when
executed shall be deemed to be an original, but all of which taken together shall constitute one
and the same agreement.
SECTION 5. Governing Law. This Amendment shall be deemed to be a contract made under
the laws of the State of Delaware and for all purposes shall be governed by and construed in
accordance with the laws of such State applicable to contracts to be made and performed entirely
within such State.
