         WHEREAS, the Dolphins own and operate the Miami Dolphins, a
professional football team and member of the National Football League, which
presently is scheduled to play its home games at Pro Player Stadium in Miami,
Florida (the "Stadium"); and Hydron desires to be a sponsor of the Miami
Dolphins for certain entertainment and promotional purposes in connection with
the Miami Dolphins including its home games during the term of this Agreement;
and

         NOW THEREFORE, for good and valuable consideration, the receipt of
which is hereby acknowledged, Hydron and the Dolphins hereby agree as follows:

         1.       TERM OF AGREEMENT

                  1.1 The term of this Agreement shall commence on the date
hereof and terminate upon the conclusion of the week following the conclusion of
the Dolphins 2000 regular season or post season, if applicable (the "Term" or
"Initial Term"). However, this Agreement may be earlier terminated in accordance
with the provisions hereof.

                  1.2 Hydron shall have the right to terminate this Agreement
upon written notice to Dolphins at any time between November 1, 1997 and
December 15, 1997, in which event this Agreement shall be terminated following
the Dolphins last 1997 regular or post-season game, if any. If Hydron does not
timely exercise its right to terminate this Agreement, then Hydron agrees that
this Agreement shall continue for the entire four (4) year term unless earlier
terminated pursuant to Section 8 of this Agreement.

         2.       SPONSORSHIP RIGHTS

                  2.1 For the Term of this Agreement, the Dolphins will provide
Hydron with certain advertising and promotional benefits as are set forth in and
in accordance with Exhibit "A" attached hereto and made a part hereof (the
"Sponsorship Rights").

                  2.2 For the Term of this Agreement, Hydron shall be designated
as a sponsor of the Dolphins in the Sunscreen/Skin Care Category (as defined
below) and a licensee of the Marks (as defined below) in the Sunscreen/Skin
Category by the Dolphins. For purposes of this Agreement, the term
"Sunscreen/Skin Care Category" means the product category consisting of

                  2.3 The Sponsorship Rights granted by the Dolphins to
Hydron are subject to


<PAGE>

termination in whole or in part at any time upon written notice to Hydron if
such Sponsorship Rights conflict with any exclusive advertising rights granted
by NFL Properties, Inc. to one of its advertisers or sponsors. In the event of
any such termination of exclusivity, the non-terminated Sponsorship Rights
granted to Hydron by the Dolphins shall nonetheless continue for the remainder
of the Term and the provisions of Section 8.2 shall apply. As of the date
hereof, the Dolphins have no knowledge of any claim by NFL Properties that the
Sponsorship Rights violate or conflict with exclusive rights granted by NFL
Properties.

         3.       CONSIDERATION

                  3.1 In consideration of the Sponsorship Rights granted to
Hydron hereunder:

                            (a) Hydron shall pay to the Dolphins an aggregate
amount of $96,000 (plus any applicable sales and other taxes) as follows: Hydron
shall pay Dolphins the sum of $24,000 (plus any applicable sales and other
taxes) on July 1, 1997, July 1, 1998, July 1, 1999 and July 1, 2000.

                  3.2 In the event that the consideration is not paid by Hydron
on or before the applicable payment due date, said failure to pay shall be
considered a material breach by Hydron, and the Dolphins may elect to charge
Hydron a late fee of 1.5% per month of the payment then due and owing until it
is paid in full. The Dolphins agree to provide written notice to Hydron of the
failure to receive any payment, and Hydron shall have a five (5) business day
period following delivery of written notice in which to cure the payment default
before the Dolphins may elect to terminate this Agreement and pursue applicable
remedies. It is agreed by Hydron that any such election of remedies does not
waive any other remedies for breach of contract available to the Dolphins.

                  3.3 Except as otherwise specifically provided in this
Agreement, including Exhibit "A", each of the parties shall pay its own expenses
of performing its obligations under this Agreement.

         4.       USE OF MARKS

                  4.1 Hydron and the Dolphins may use the name, logos, colors,
trademarks, service marks, or other identifying features ("Marks") of the other,
as specifically contemplated in connection with the Sponsorship Rights, subject
to any limitations set forth in this Agreement.

                  4.2 All advertising material and any use of the other parties'
Marks by a party is subject to the prior written approval of the Mark owner.
Either party shall submit all such materials or proposed usage of a Mark to the
other party at least two weeks prior to its intended use. The Mark owner shall
have the right to inspect and require changes or deletions (including the right
to disapprove of such advertisement or use of Marks in their entirety) of
advertising and promotional copy or material that the Mark owner may deem to be
contrary to its policies or best interests. Such requirements will not be
unreasonably imposed, and the foregoing approvals and


                                        2

<PAGE>

requirements will be consistently given and imposed on all sponsors or users of
the Marks, as the case may be.

                  4.3 Any and all public announcements or press releases by or
on behalf of the other party regarding the Sponsorship Rights or the details of
this Agreement shall be subject to the consent of the other party, and each
party shall have the right to approve in advance the contents and timing
thereof. Notwithstanding the foregoing, the Dolphins acknowledge that Hydron, as
a publicly held company, has disclosure obligations pursuant to the federal
securities laws. Hydron agrees to take the comments of the Dolphins into account
in preparing and disseminating such disclosure, but notwithstanding comments
from the Dolphins, Hydron shall make such disclosure as may be required by law.

                  4.4 For purposes of this Agreement, the Dolphins and Hydron
expressly recognize that the Marks are the unique, valid and exclusive property
of the respective owner of the Mark. The Dolphins and Hydron agree that they
shall not, either during the term of this Agreement or thereafter, directly or
indirectly, contest the validity of the other's Marks or any of the
registrations pertaining thereto, in the United States or elsewhere, nor adopt
the other's Marks or any term, word, mark or designation which is in any aspect
confusingly similar to the other's Marks. The Dolphins and Hydron specifically
acknowledges that any use of the Marks pursuant to this Agreement shall not
create for the Dolphins or Hydron any right, title or interest in the other's
Marks. The Dolphins and Hydron further agree that they will not at any time do
or cause to be done any act or thing, directly or indirectly, which contests or
in any way impairs or tends to impair any part of the right, title and interest
of the other in its Marks; and the Dolphins and Hydron shall not, in any manner,
represent that it has any ownership interest in the other's Marks or the
registrations therefor. Upon termination of this Agreement, the Dolphins and
Hydron shall immediately terminate all use of the other's Marks.

                  4.5 Hydron expressly recognizes that the Dolphins have
previously granted the exclusive rights to license and sublicense its Marks to
NFL Properties, Inc., and that the grant to Hydron of the right to use the Marks
is subject to the prior approval of NFL Properties, Inc. In the event that such
approval is not so given by NFL Properties, Inc., then such usage rights of
Hydron shall immediately terminate. The Dolphins represent that they will use
reasonable efforts to obtain the consent of NFL Properties, Inc. to the
execution and performance of this Agreement prior to their execution hereof. In
any such event, the provisions of Section 8.2 will apply.

         5.       STADIUM POLICY; GOVERNING LEAGUE POLICIES

                  5.1 Hydron and the Dolphins agree that this Agreement shall be
performed in accordance with rules and policies of the Stadium as may be
applicable to this Agreement, if any. The Dolphins will advise Hydron of any
development of or changes in these rules and policies that might adversely
affect the terms of this Agreement.


                  5.2 The parties agree that this Agreement shall automatically
be subject to any new or amended National Football League (the "NFL") rules or
regulations applicable to advertising or promotional benefits provided by NFL
member teams to its sponsors effective as

                                        3

<PAGE>

of the date such regulation shall take effect and that this Agreement shall
incorporate and be subject to the Constitution, By-Laws, rules and regulations,
the duly authorized resolutions of the governing body, the decrees and rulings
of the commissioner and the terms and conditions of any and all agreements to
which the NFL is a party and as to which the NFL has bound its member clubs
(collectively all of such regulations, resolutions, decrees and agreements are
referred to as the "Governing League Policies"). The Dolphins shall advise
Hydron of any changes therein which may materially and adversely affect the
Sponsorship Rights. As of the date hereof, the Dolphins have no knowledge of any
claim by the NFL that the Sponsorship Rights violate any Governing League Rules.

                  5.3 Without limiting any other potential uses of the Dolphins'
Marks, Hydron agrees that the Dolphins may allow or authorize any League Sponsor
(as defined below) to engage in advertising and promotional activities in the
Dolphins' local market (including, without limitation, the Stadium), or
otherwise provide benefits to such League Sponsor, if such League Sponsor is
entitled to engage in such activities or receive such benefits pursuant to any
sponsorship or promotional licensing arrangement now or hereafter entered into
between such League Sponsor and the NFL or any of its affiliates (including,
without limitation, NFL Properties, Inc., NFL Enterprises, Inc. and NFL Films,
Inc.). For purposes of this Agreement the term, "League Sponsor" shall mean any
person or entity which currently is, or at any time becomes a sponsor or
promotional licensee of or with respect to any NFL event or program now or
hereafter in existence. By way of illustration only and without limiting the
generality of the foregoing, League Sponsors may place advertising and
promotional materials (including displays) in the Stadium, in connection with a
League event, such as the Super Bowl.

                  5.4 If any rule or regulation of the Stadium, or any Governing
League Policy as described in Sections 5.1, 5.2 or 5.3 requires the termination
or revision of any Sponsorship Right, such Sponsorship Right shall be revised or
terminated upon written notice to Hydron and the provisions of Section 8.2 shall
apply to such termination or revisions.

<PAGE>

                  9.2 It is mutually understood and agreed that Hydron and the
Dolphins, and their respective partners, officers, employees, representatives
and agents are, at all times, herein, acting and performing separately and
independently of each other and are in no way or manner to represent themselves
as agents or employees of the other party. As such, no party shall incur any

                  9.3 All notices required to be given hereunder shall be
properly served if in writing and delivered either by (i) personal delivery,

hereunder without the prior written consent of the other party, except that
Hydron may assign its rights and obligations under this Agreement to its parent,
its successor or to an affiliate (as such term is defined under the rules and
regulations promulgated under the federal securities laws of the U.S.) upon the
reasonable consent of the Dolphins that such affiliate assignee has the
financial means and corporate authority to perform such obligations and Hydron
may not withhold its consent to an assignment of this Agreement in the event of
a merger or reorganization of the Dolphins, a sale of all or substantially all
of the Dolphins' assets or a consolidation of the Dolphins with any of its
affiliates or related parties.

                  9.7 In the event that the performance of this Agreement is
prevented because of an act of nature or force majeure or if the exhibition of
any scheduled home games of the Dolphins is canceled because of strike, lockout,

Dolphins hereby agree, in good faith, to attempt to reschedule any aspect of the
Sponsorship Rights which is prevented from occurring as scheduled, at such date
as may be

                                       7

<PAGE>

reasonably agreeable to the Dolphins and Hydron. If one or more events or
benefits are unable to be rescheduled during the Term of this Agreement, the
provisions of Section 8.2 shall apply in the same manner as if such failure to
reschedule caused a termination of a Sponsorship Right. Nothing stated in this
Agreement grants Hydron any sponsorship, promotional or other rights with
respect to any Super Bowl, Pro Bowl or NFL conference championship or play-off
games or any other football game(s) which are not part of the preseason or
regular season schedule of games to be played at home by the Miami Dolphins.

                  9.8 This Agreement (including Exhibit "A") sets forth the
entire understanding and agreement of the parties hereto with respect to its
subject matter and supersedes all prior under standings or agreements between
the parties relating to the same subject matter. Any amendments or modifications
to this Agreement shall be in writing, as mutually agreed upon by both parties.


         IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed by their respective authorized representatives, effective as of the
date first shown above.
