                                  AMENDMENT TO
                             CT COMMUNICATIONS, INC.
                      1995 COMPREHENSIVE STOCK OPTION PLAN

     The CT Communications, Inc. 1995 Comprehensive Stock Option Plan (the
"Plan"), is hereby amended as set forth below:

     1.   Section 1.2(h) of the Plan is hereby amended and restated to read as
          follows:

          "Fair Market Value" means the value of a share of Common Stock,
          determined as follows: if on the determination date the Common Stock
          is listed on an established national or regional stock exchange, is
          admitted to quotation on The Nasdaq Stock Market, Inc., or is publicly
          traded on an established securities market, the Fair Market Value of a
          share of Common Stock shall be the closing price of the Common Stock
          on such exchange or in such market (if there is more than one such
          exchange or market the Board of Directors shall determine the
          appropriate exchange or market) at the time of grant or such other
          determination date (or if there is no such reported closing price, the
          Fair Market Value shall be the mean between the highest bid and lowest
          asked prices or between the high and low sale prices on such trading
          day) or, if no sale of Common Stock is reported for such trading day,
          on the next preceding day on which any sale shall have been reported.
          If the Common Stock is not listed on such an exchange, quoted on such
          system or traded on such a market, Fair Market Value shall be the
          value of the Common Stock as determined by the Board of Directors in
          good faith.

     2.   The Plan shall otherwise be unchanged by this Amendment.

                            *          *          *

         The foregoing Amendment to the Plan was duly adopted and approved by
the Board of Directors of the Corporation by resolution at a meeting held on
February 22, 2001.

[57]                                ABSTRACT

A diagnostic syringe actuator device for use in combination with a syringe in
the removal of tissue, fluid and/or cells for the diagnosis of pathological
processes wherein the syringe includes a hollow syringe body having a
longitudinally movable syringe plunger at least partially disposed therein with
a probe needle attached to the distal end portion comprising a hollow retractor
tube having a longitudinally movable retractable piston disposed therein, a
longitudinally movable retractable piston disposed therein, a longitudinally
movable syringe plunger sabot disposed within the hollow retractor tube, a
sabot lock mechanism selectively movable between a locked and unlocked position
disposed to engage the syringe plunger sabot when in the locked position to
maintain the syringe plunger and the syringe plunger sabot in the advanced
position and to disengage the syringe is plunger sabot when moved to the
unlocked position such that the syringe plunger sabot and the syringe plunger
move from the advanced position when the retractable piston has been at least
partially retracted within the hollow retractor tube creating a vacuum therein
whereby material is extracted from a patient through the probe needle and into
the hollow syringe body.
