                                       OF

                          THE SPECTRANETICS CORPORATION

                             a Delaware corporation


                  WHEREAS, the Board of Directors has previously adopted the
Bylaws of the Corporation (the "Bylaws");

                  WHEREAS, pursuant to the Bylaws, the Board of Directors has
the power to adopt, amend or repeal the bylaws of the Corporation; and

                  WHEREAS, the Board of Directors now desires to amend the
Bylaws to provide that a stockholder must give timely notice in writing to the
Secretary of the Company of any nominations or other business to be properly
brought before an annual or special meeting.

                  NOW, THEREFORE, the Bylaws are hereby amended as follows:

                  1. Notice of Stockholder Business and Nominations. Section 1.3
of the Bylaws shall be deleted in its entirety and shall be replaced with the
following:

         "Section 1.3  Notice of Stockholder Business and Nominations.

                  (A) Annual Meetings of Stockholders. (1) Nominations of
         persons for election to the Board of Directors of the Corporation and
         the proposal of business to be considered by the stockholders may be
         made at an annual meeting of stockholders only (a) pursuant to the
         Corporation's notice of meeting (or any supplement thereto), (b) by or
         at the direction of the Board of Directors or (c) by any stockholder of
         the Corporation who was a stockholder of record of the Corporation at
         the time the notice provided for in this Section 1.3 is delivered to
         the Secretary of the Corporation, who is entitled to vote at the
         meeting and who complies with the notice procedures set forth in this
         Section 1.3.

                           (2) For nominations or other business to be properly
         brought before an annual meeting by a stockholder pursuant to clause
         (c) of paragraph (A)(1) of this Section 1.3, the stockholder must have
         given timely notice thereof in writing to the Secretary of the
         Corporation and any such proposed business other than the nominations
         of persons for election to the Board of Directors must constitute a
         proper matter for stockholder action. To be timely, a stockholder's
         notice shall be delivered to the Secretary at the principal executive
         offices of the Corporation not later than the close of business on the
         sixtieth day nor earlier than the close of business on the ninetieth
         day prior to the first anniversary of the preceding year's annual
         meeting (provided, however, that in the event that the date of the
         annual meeting is more than thirty days before or after the date of the


         first anniversary of the preceding year's annual meeting, notice by the
         stockholder to be timely must be so received not earlier than the close
         of business on the ninetieth day prior to such annual meeting and not
         later than the close of business on the later of the sixtieth day prior
         to such annual meeting or the tenth day following the day on which
         public announcement of the date of such meeting is first made by the
         Corporation). In no event shall the public announcement of an
         adjournment or postponement of an annual meeting commence a new time
         period (or extend any time period) for the giving of a stockholder's
         notice as described above. Such stockholder's notice shall set forth:
         (a) as to each person whom the stockholder proposes to nominate for
         election as a director (i) all information relating to such person that
         is required to be disclosed in solicitations of proxies for election of
         directors in an election contest, or is otherwise required, in each
         case pursuant to and in accordance with Regulation 14A under the
         Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
         (ii) such person's written consent to being named in the proxy
         statement as a nominee and to serving as a director if elected; (b) as
         to any other business that the stockholder proposes to bring before the
         meeting, a brief description of the business desired to be brought
         before the meeting, the text of the proposal or business (including the
         text of any resolutions proposed for consideration and in the event
         that such business includes a proposal to amend the By-laws of the
         Corporation, the language of the proposed amendment), the reasons for
         conducting such business at the meeting and any material interest in
         such business of such stockholder and the beneficial owner, if any, on
         whose behalf the proposal is made; and (c) as to the stockholder giving
         the notice and the beneficial owner, if any, on whose behalf the
         nomination or proposal is made (i) the name and address of such
         stockholder, as they appear on the Corporation's books, and of such
         beneficial owner, (ii) the class and number of shares of capital stock
         of the Corporation which are owned beneficially and of record by such
         stockholder and such beneficial owner, (iii) a representation that the
         stockholder is a holder of record of stock of the Corporation entitled
         to vote at such meeting and intends to appear in person or by proxy at
         the meeting to propose such business or nomination, and (iv) a
         representation whether the stockholder or the beneficial owner, if any,
         intends or is part of a group which intends (a) to deliver a proxy
         statement and/or form of proxy to holders of at least the percentage of
         the Corporation's outstanding capital stock required to approve or
         adopt the proposal or elect the nominee and/or (b) otherwise to solicit
         proxies from stockholders in support of such proposal or nomination.
         The foregoing notice requirements shall be deemed satisfied by a
         stockholder if the stockholder has notified the Corporation of his or
         her intention to present a proposal at an annual meeting in compliance
         with Rule 14a-8 (or any successor thereof) promulgated under the
         Exchange Act and such stockholder's proposal has been included in a
         proxy statement that has been prepared by the Corporation to solicit
         proxies for such annual meeting. The Corporation may require any
         proposed nominee to furnish such other information as it may reasonably
         require to determine the eligibility of such proposed nominee to serve
         as a director of the Corporation.




                           (3) Notwithstanding anything in the second sentence
         of paragraph (A)(2) of this Section 1.3 to the contrary, in the event
         that the number of directors to be elected to the Board of Directors of
         the Corporation at an annual meeting is increased and there is no
         public announcement by the Corporation naming the nominees for the
         additional directorships at least one hundred days prior to the first
         anniversary of the preceding year's annual meeting, a stockholder's
         notice required by this Section 1.3 shall also be considered timely,
         but only with respect to nominees for the additional directorships, if
         it shall be delivered to the Secretary at the principal executive
         offices of the Corporation not later than the close of business on the
         tenth day following the day on which such public announcement is first
         made by the Corporation.

                  (B) Special Meetings of Stockholders. Only such business shall
         be conducted at a special meeting of stockholders as shall have been
         brought before the meeting pursuant to the Corporation's notice of
         meeting. Nominations of persons for election to the Board of Directors
         may be made at a special meeting of stockholders at which directors are
         to be elected pursuant to the Corporation's notice of meeting (1) by or
         at the direction of the Board of Directors or (2) provided that the
         Board of Directors has determined that directors shall be elected at
         such meeting, by any stockholder of the Corporation who is a
         stockholder of record at the time the notice provided for in this
         Section 1.3 is delivered to the Secretary of the Corporation, who is
         entitled to vote at the meeting and upon such election and who complies
         with the notice procedures set forth in this Section 1.3. In the event
         the Corporation calls a special meeting of stockholders for the purpose
         of electing one or more directors to the Board of Directors, any such
         stockholder entitled to vote in such election of directors may nominate
         a person or persons (as the case may be) for election to such
         position(s) as specified in the Corporation's notice of meeting, if the
         stockholder's notice required by paragraph (A)(2) of this Section 1.3
         shall be delivered to the Secretary at the principal executive offices
         of the Corporation not earlier than the close of business on the
         ninetieth day prior to such special meeting and not later than the
         close of business on the later of the sixtieth day prior to such
         special meeting or the tenth day following the day on which public
         announcement is first made of the date of the special meeting and of
         the nominees proposed by the Board of Directors to be elected at such
         meeting. In no event shall the public announcement of an adjournment or
         postponement of a special meeting commence a new time period (or extend
         any time period) for the giving of a stockholder's notice as described
         above.

                  (C) General. (1) Only such persons who are nominated in
         accordance with the procedures set forth in this Section 1.3 shall be
         eligible to be elected at an annual or special meeting of stockholders
         of the Corporation to serve as directors and only such business shall
         be conducted at a meeting of stockholders as shall have been brought
         before the meeting in accordance with the procedures set forth in this
         Section 1.3. Except as otherwise provided by law, the chairman of the
         meeting shall have the power and duty (a) to determine whether a
         nomination or


         any business proposed to be brought before the meeting was made or
         proposed, as the case may be, in accordance with the procedures set
         forth in this Section 1.3 (including whether the stockholder or
         beneficial owner, if any, on whose behalf the nomination or proposal is
         made solicited (or is part of a group which solicited) or did not so
         solicit, as the case may be, proxies in support of such stockholder's
         nominee or proposal in compliance with such stockholder's
         representation as required by clause (A)(2)(c)(iv) of this Section 1.3)
         and (b) if any proposed nomination or business was not made or proposed
         in compliance with this Section 1.3, to declare that such nomination
         shall be disregarded or that such proposed business shall not be
         transacted. Notwithstanding the foregoing provisions of this Section
         1.3, if the stockholder (or a qualified representative of the
         stockholder) does not appear at the annual or special meeting of
         stockholders of the Corporation to present a nomination or business,
         such nomination shall be disregarded and such proposed business shall
         not be transacted, notwithstanding that proxies in respect of such vote
         may have been received by the Corporation.

                           (2) For purposes of this Section 1.3, "public
         announcement" shall include disclosure in a press release reported by
         the Dow Jones News Service, Associated Press or comparable national
         news service or in a document publicly filed by the Corporation with
         the Securities and Exchange Commission pursuant to Section 13, 14 or
         15(d) of the Exchange Act.

                           (3) Notwithstanding the foregoing provisions of this
         Section 1.3, a stockholder shall also comply with all applicable
         requirements of the Exchange Act and the rules and regulations
         thereunder with respect to the matters set forth in this Section 1.3.
         Nothing in this Section 1.3 shall be deemed to affect any rights (a) of
         stockholders to request inclusion of proposals in the Corporation's
         proxy statement pursuant to Rule 14a-8 under the Exchange Act or (b) of
         the holders of any series of Preferred Stock to elect directors
         pursuant to any applicable provisions of the certificate of
         incorporation."

                  2. Miscellaneous. After the date of this Amendment, each
reference in the Bylaws to the Bylaws shall mean and refer to the Bylaws as
amended hereby. Except as provided in this Amendment, the Bylaws shall remain in
full force and effect and are hereby ratified and confirmed.
