Form of Letter to Shareholders

                      [THE QUIGLEY CORPORATION. LETTERHEAD]

                                                              September 25, 1998

To Our Shareholders:

          Your Board of Directors has recently declared a dividend  distribution
of Common Share Purchase Rights (the "Rights"),  thereby  creating a Shareholder
Rights Plan (the "Plan").  This letter describes the Plan and the reasons of the
Company's Board of Directors (the "Board") for adopting it.

           The Rights contain provisions to protect shareholders in the event of
an unsolicited attempt to acquire the Company,  including a gradual accumulation
of shares in the open market,  a partial or two-tier  tender offer that does not
treat all shareholders  equally, a squeeze-out merger and other abusive takeover
tactics which the Board believes are not in the best interests of  shareholders.
These  tactics  unfairly  pressure  shareholders,  squeeze  them  out  of  their
investment  without  giving them any real  choice and  deprive  them of the full
value of their shares.

           Over 2,000 companies,  including approximately 60% of the Fortune 500
companies,  have  issued  rights to protect  their  shareholders  against  these
tactics.  We consider the Plan to be the best available means of protecting both
your right to retain your equity  investment in The Quigley  Corporation and the
full value of that investment,  while not foreclosing a fair acquisition bid for
the Company.

           The Rights are not  intended to prevent a takeover of the Company and
will not do so. However, they should deter any attempt to acquire the Company in
a manner or on terms not approved by the Board.  The Rights are designed to deal
with the very serious problem of another person or company using abusive tactics
to deprive the Company's Board and its  shareholders of any real  opportunity to
determine the destiny of the Company.

           The Rights may be  redeemed by the Board for one cent per Right prior
to the accumulation, through open-market purchases, a tender offer or otherwise,
of 15% or more of the Company's shares by a single acquiror or group. Because of
the  redemption  feature,  the Rights  should not  interfere  with any merger or
business combination approved by the Board prior to that time.

           The Board  believes  that the  issuance of the Rights does not in any
way weaken the financial  strength of the Company or interfere with its business
plans.  The  issuance  of the Rights  has no  dilutive  effect,  will not affect
reported earnings per share, is




not taxable to the  Company or to you,  and will not change the way in which you
can presently  trade the  Company's  shares.  As explained in detail below,  the
Rights will only be  exercisable  if and when the problem arises which they were
created  to deal with.  They will then  operate to  protect  you  against  being
deprived of your right to share in the full measure of your Company's  long-term
potential.

          The Board was aware  when it acted  that  some  people  have  advanced
arguments  that  securities  of  the  sort  we  are  issuing  deter   legitimate
acquisition  proposals.  We carefully  considered these views and concluded that
the arguments are speculative and do not justify  leaving  shareholders  without
any  protection  against  unfair  treatment by an acquiror,  who,  after all, is
seeking his own company's  advantage,  not yours.  The Board believes that these
Rights  represent a sound and reasonable  means of addressing the complex issues
of corporate governance and policy.

           The Rights  were issued on  September  25,  1998 to  shareholders  of
record on that date and will expire in ten years. Initially, the Rights will not
be  exercisable,  certificates  will  not be sent to you,  and the  Rights  will
automatically trade with the common shares.  However, ten days after a person or
group  acquires 15% or more of the  Company's  shares,  or ten business days (or
such later  date as may be  determined  by the Board  prior to a person or group
acquiring 15% or more of the Company's shares) after a person or group announces
an offer the  consummation  of which would result in such person or group owning
15% or more of the shares (even if no purchases actually occur), the Rights will
become  exercisable and separate  certificates  representing  the Rights will be
distributed.  We expect that the Rights will begin to trade  independently  from
the  Company's  shares at that time.  At no time will the Rights have any voting
power.

          When the Rights first become exercisable,  unless a holder is a person
or group who has acquired 15% or more of the Company's shares,  that holder will
be entitled to buy from the Company one share of Common Stock for $45.00. If the
Company is involved in a merger or other business  combination  with a person or
group or  affiliate  at any time after that person or group has  acquired 15% or
more of the Company's  shares,  the Rights will entitle a holder to buy a number
of shares of common  stock of the  acquiring  company  having a market  value of
twice the  exercise  price of each  Right.  For  example,  if at the time of the
business combination the acquiring company's stock has a per share value of $30,
the holder of each Right would be entitled to receive 3 shares of the  acquiring
company's common stock for $45, i.e., at a 50% discount.

          If any  person  or  group  acquires  15%  or  more  of  the  Company's
outstanding  common  stock,  the  "flip-in"  provision  of the  Rights  will  be
triggered  and the Rights will  entitle a holder  (other than such person or any
member of such group) to buy a

                                       -2-


number of additional shares of common stock of the Company having a market value
of twice  the  exercise  price of each  Right.  Thus,  if at the time of the 15%
acquisition  the Company's  stock were to have a market value per share equal to
$10,  the holder of each  Right  (other  than such  person or any member of such
group) would be entitled to receive 9 shares of the  Company's  common stock for
$45.

           Following  the  acquisition  by any person or group of 15% or more of
the Company's  common stock,  but only prior to the  acquisition  by a person or
group of a 50% stake,  the Board  will also have the  ability  to  exchange  the
Rights  (other than  Rights held by such person or group),  in whole or in part,
for  one  share  of  common  stock  per  Right.  This  provision  will  have  an
economically  dilutive  effect on the  acquiror,  and  provide  a  corresponding
benefit  to the  remaining  rightsholders,  that is  comparable  to the  flip-in
without  requiring  rightsholders  to go  through  the  process  and  expense of
exercising their Rights.

          While,  as noted  above,  the  distribution  of the Rights will not be
taxable to you or the Company,  shareholders  may recognize  taxable income upon
the occurrence of certain subsequent events.

           In declaring the Rights dividend, we have expressed our confidence in
the future of the Company and our determination  that you, our shareholders,  be
given every opportunity to participate fully in that future.

                              On behalf of the Board of Directors,


                              By________________________________________________
