      Pursuant to the provisions of Nevada Revised Statutes, Section 78.195, of
the corporation laws of the State of Nevada, the undersigned corporation,
FiberCore, Inc. (the "Corporation"), hereby adopts the following Designation of
Rights, Privileges, and Preferences of Series A Preferred Stock (the
"Designation"):

      FIRST:  The name of the Corporation is FiberCore, Inc.

      SECOND: The following resolution establishing a series of preferred stock
designated as the "Series A Preferred Stock" consisting of one (1) share, par
value $0.001, was duly adopted by the board of directors of the Corporation on
December 18, 2000, in accordance with the articles of incorporation of the
Corporation and the corporation laws of the State of Nevada:

      RESOLVED, there is hereby created a series of preferred stock of the
      Corporation to be designated as the "Series A Preferred Stock" consisting
      of one (1) share, par value $0.001 (referred to herein as the "Preferred
      Stock"), with the following powers, preferences, rights, qualifications,
      limitations, and restrictions:

      1.    Dividends.  No dividends shall be payable with respect to the
      Preferred Stock.

      2.    Liquidation.  No distribution shall be made with respect to the
      Preferred Stock in the event of any voluntary or involuntary
      liquidation (whether complete or partial), dissolution, or winding up
      of the Corporation.

      3.    Conversion. The Preferred Stock shall not be convertible into shares
      of common stock of the Corporation.

      4.    Voting Rights. The Preferred Stock shall be entitled to vote as a
      separate class (i) to elect the Series A Directors (defined in Section
      5.01 below); and (ii) on any resolution proposed for adoption by the
      stockholders of the Corporation that seeks to amend, alter or repeal the
      provisions of the Corporation's articles of incorporation or this
      Designation so as to adversely affect any right, preference, privilege or
      voting power of the Preferred Stock or the holder thereof. In addition,
      without the approval of the holder of the Preferred Stock ("Series A
      Holder"), the Corporation shall not become subject to any restriction on
      the Preferred Stock other than restrictions arising under the general
      corporation laws of the State of Nevada or existing under the articles of
      incorporation of the Corporation as in effect on November 27, 2000. The
      Preferred Stock shall have no other voting rights.

      5.    Series A Directors.

            5.01.  Appointment.  The Series A Holder shall be entitled to
      appoint one or more members of the Corporation's Board of Directors as
      provided in this Section 5.01.  Members of the Corporation's Board of
      Directors appointed by the Series A Holder are referred to as "Series A
      Directors."

            (i)  So long as the Preferred Stock remains outstanding, the holder
      of the Series A Stock ("Series A Holder") shall be entitled to appoint one
      Series A Director unless a Tyco Director (defined below) is already a
      member of the Corporation's Board of Directors, in which event, the Series
      A Holder may designate one such Tyco Director as a Series A Director.

            (ii)  Upon the occurrence and during the continuation of an Event of
      Default under the terms of that certain Guarantor Indemnification
      Agreement dated as of December 20, 2000 (the "Indemnification Agreement")
      by and among the Corporation, Tyco International Group S.A. (the
      "Guarantor"), and the Managing Shareholders identified therein, the Series
      A Holder shall have the right, but not the obligation, to: (a) cause an
      increase in the size of the Corporation's Board of Directors sufficient to
      allow the appointment of directors described in this Section 5.01; and (b)
      appoint a sufficient number of additional Series A Directors such that,
      following such appointments, the Series A Directors, together with other
      members of the Corporation's Board of Directors (if any) employed by Tyco
      International Ltd. or any of its subsidiaries (each, a "Tyco Director"),
      constitute a majority of the Corporation's whole Board of Directors. If
      the Series A Holder elects to exercise its rights under this subsection
      5.01(ii), it shall do so by delivering written notice (a "Designation
      Notice") to the Corporation specifying the names of the individuals to be
      appointed as additional Series A Directors. The appointments of the
      additional Series A Directors shall become effective immediately upon
      delivery of the Designation Notice in accordance with the terms of Section
      7.03 of these Designations.

            5.02.  Classification. The classification of the Series A Directors
      shall be determined in accordance with Article II, Section 1 of the
      Corporation's bylaws, with the Series A Directors to be divided, upon
      their initial appointment or election, among the classes of Directors as
      follows:

            (i)  If the number of Series A Directors is one, two, or three, they
      shall be placed in separate classes from each other;

            (ii) If the number of Series A Directors is more than three, they
      shall be divided as evenly as possible among the three classes of
      directors.

            5.03.  Vacancies.  If the office of any Series A Director becomes
      vacant by reason of death, resignation, disqualification, removal,
      expansion of the Board or other causes, a majority of the Series A
      Directors remaining in office, even if they constitute less than a quorum,
      may elect a successor for the unexpired term and until his or her
      successor is elected and qualified. Notwithstanding the foregoing, in the
      event no Series A Director remains a member of the Board, the Series A
      Holder will fill vacant offices of Series A Directors by delivering
      written notice to the Board specifying the names of the individuals to
      fill such offices.

            5.04.  Nomination and Election.  Upon the expiration of the term of
      any Series A Director, the Series A Holder shall have the exclusive right
      to nominate and, voting as a separate class, to reelect or elect a
      successor to such Series A Director.

            5.05.  Rights, Powers, and Duties. Except as specified herein, the
      Series A Directors shall have the same rights, powers and duties as the
      other members of the Corporation's Board of Directors.

            5.06. Removal of Series A Directors. Upon termination of the
      Indemnification Agreement pursuant to Section 9.3 thereof: (i) the
      position and terms of office of Series A Directors shall be immediately
      terminated thereby, and (b) the Series A Holder shall be deemed to have
      voted such share to remove any Series A Directors from the Corporation's
      Board of Directors.

      6.    Cancellation of Preferred Stock.  Upon termination of the
      Indemnification Agreement pursuant to Section 9.3 thereof and removal
      of the Series A directors as set forth above, the Preferred Stock shall
      be canceled and cease to be outstanding.

      7.    Additional Provisions.

            7.01. No change in the provisions of the Preferred Stock set forth
      in this Designation affecting any interest of the holder of the share of
      Preferred Stock shall be binding or effective unless such change shall
      have been approved or consented to by the Series A Holder in the manner
      provided in the corporation laws of the State of Nevada, as the same may
      be amended from time to time.

            7.02. The share of Preferred Stock may be transferred to Tyco
      International Ltd. or any of its direct or indirect subsidiaries, provided
      that Tyco International Ltd. controls at least 51% of the voting
      securities of such direct or indirect subsidiary, but otherwise shall not
      be transferable without the approval of the Corporation's Board of
      Directors. The share of Preferred Stock shall be transferable only on the
      books of the Corporation maintained at its principal office, on delivery
      thereof duly endorsed by the holder or his duly authorized attorney or
      representative or accompanied by proper evidence of succession,
      assignment, or authority to transfer. In all cases of transfer by an
      attorney, the original letter of attorney, duly approved, or an official
      copy thereof, duly certified, shall be deposited and remain with the
      Corporation. On any registration or transfer, the Corporation shall
      deliver a new certificate representing the share of Preferred Stock to the
      person entitled thereto.

            7.03. All notices, communications and distributions hereunder shall
      be given or made to the intended recipient at the address specified in the
      Indemnification Agreement, or at such other address as the addressee may
      hereafter specify for the purpose by written notice in accordance with
      this section. Such Notices and other communications shall be given or made
      in writing and may be delivered by hand, by overnight courier, by
      facsimile, or by first-class mail (return receipt requested). All such
      notices and other communications shall be deemed to have been duly given
      (a) if delivered by hand, overnight courier or first-class mail (return
      receipt requested), on the date of delivery; and (b) if transmitted by
      facsimile (with receipt confirmed by machine), on the date of transmission
      if the same is a Business Day or, if not a Business Day, on the first
      Business Day after the date of transmission.
