Dear Ron:


Effective  as of April 6, 1998,  I hereby  tender my  resignation  as  director,
secretary, and treasurer of Titan Technologies,  Inc. I shall continue on in the
capacity  of  general  counsel,  should  you wish me to,  to help  wind up a few
matters, including finalization of the contract with Tyre Recycling Europe, Ltd.
(Jeremy  Francis),  until you.  can find  someone  else.  You have the option of
keeping me on at my current salary or paying me at the rate of $125.00 per hour.
Of  course,  since I haven't  been paid at all for well over a month,  these are
claims that will remain rather  speculative  at best. As I have already made you
emphatically aware, the precipitating  reason for this resignation is my refusal
to continue on a Board of  Directors  which is  betraying  the  interests of its
shareholders. Ron Allred has refused to turn over research data in a contractual
disclosure  required by Cytec  Fiberite,  Inc. as a condition  precedent  to the
purchase  by Cytec of Titan's  carbon  composites  recycling  technology  unless
Allred receives personally a portion of the license fee to be paid Titan. As you
know,  all research  data,  for which Allred was well  compensated by government
grants,  were obtained under the auspices of an exclusive research contract with
the Company which  contemplated  that those results would belong to the Company.
Allred has no right to withold them when they are  requested  by Titan,  and his
attempt to do so is sheer economic coercion.  Given his special knowledge of the
Company's  financial  condition as director of Titan, his actions are tantamount
to his pointing a gun to our head. You believe it is somehow unreasonable for me
to call unlawful conduct unlawful. I cannot in good conscience do anything else,
especially since you already assured me you had enlisted Allred's cooperation in
the  Cytec  Fiberite  matter  diplomatically.  Allred's  conduct  has not been a
surprise to me, and I have asked you to help me confront  and deal with it since
at least last June.  Furthermore,  you and Allred have discussed stripping Titan
of the major part of its assets to form a new  company in which Titan would be a
minor  participant  through an equity position  equivalent to Allred's and other
Titan  insiders.  The subject arose as recently as last Friday and goes at least
as far back as last summer when AbTech proposed buying Titan out for $100,000.00
and forming a new  corporation  with Titan as a minority  shareholder.  Over and
over again I have told you that this kind of  transaction  would be unlawful and
that planning by management  and  commitment of scarce  corporate  funds to help
effect it  constitutes  diversion  and  breach of  fiduciary  duty.  Failure  to
disclose  this  intent  on  management's  part  is  very  possibly   fraudulent.
Certainly,  if financing is realistically  available for such a new venture,  it
would  probably be available for Titan on some basis from the same  sources.  As
President  of Titan,  it is your  first  duty to  secure  Titan  those  benefits
directly.  It has been a matter of real  concern  to me that your  refusal to do
anything over the last two years to develop  alternative  independent sources of
finance  may be more or less  intentional,  since  you have kept  talking  about
forming new  companies  apart from Titan based on  technologies  developed  with
Titan's funds.

I have never thought your plans were very  realistic,  but I do believe that you
have  overlooked  or ignored  possible  sources of funding  that could have kept
Titan going. There are many other areas of disagreement between us which we have
discussed in the past,  but this one is more serious than most.  While I believe
that you have always had good  intentions,  good intentions are not enough.  You
have to make  serious  efforts to make the things we have  planned for Titan and
made  representations  about to our shareholders happen, and you have simply not
been  willing to do this.  When you started  selling  stock in Titan and TRTC in
North Carolina and elsewhere to people beyond your immediate circle of relatives
and friends,  you took on a public trust.  When a secondary market was activated
for Titan's  stock and we became a  reporting  company,  these  responsibilities
increased  manifold.  You cannot continue to run Titan as your private preserve.
My primary responsibility is and has always

been to the  shareholders  as a  whole,  and I feel  my  greatest  failing  as a
director,  officer,  and general counsel of Titan has been to allow that duty to
be affected by my personal  loyalty to you. For over ten years,  I have regarded
you as a friend.  For a long time, I had in addition faith in your judgement and
drive to make Titan a success.  I have become very disillusioned and even bitter
because  you have  continually  put me into a position  recently  where I had to
choose between my friendship for you and my sense of professional duty, personal
honor, and corporate responsibility. I cannot abide this conflict any longer. If
anything, I have continued too long in what I feel is a false position.

As I said at the outset,  I shall  assist  passively to bring a few matters to a
conclusion  that may be of benefit to the Company and to perform a few remaining
ministerial  functions,  if you want me to, but I can no longer  continue  as an
officer,  executive, or director of Titan. This Company has been my dream and my
life,  even my hope for my children's  future.  It is with sincere regret that I
tender this resignation.



      Very Sincerely Yours,

                                                S/ Bruce R. Clark
