suit at any time with respect to infringers of the same patent.  If counsel
reasonably concludes that the other party is a necessary or indispensable party
to such suit, the party bringing the suit may use the name of, or join, the
other party.

If the party who has the right to bring the infringement suit does not bring the
suit within the time set forth in the preceding paragraph, the other party shall

Trademarks"), in the Territory for the Field, the party shall promptly notify
the other party in writing of the infringement or unauthorized use and Hymedix
shall have the initial right to bring a suit to abate the infringement or
unauthorized use.  In the event Hymedix does not bring a suit within thirty (30)
days of learning of the infringement or unauthorized use, ProCyte, at its
discretion and expense, may bring suit in its own name, or, if required by law,
in the name of Hymedix, retaining all proceeds from any judgment or settlement
of such suit.

                                          30

<PAGE>

ProCyte shall use commercially reasonable efforts to ensure that its use of the
Other Trademarks does not materially impair the goodwill or reputation of the
Other Trademarks.  Hymedix shall ensure that it and its licensees of the Other
Trademarks outside of the Field adhere to established standards of quality so as
not to impair the goodwill, reputation or value of the Other Trademarks.
ProCyte shall appropriately use the symbol "-Registered Trademark-" in
connection with the HYPAN-Registered Trademark- Trademark.

    17.5 REGISTRATIONS BY PROCYTE

At its expense, ProCyte shall have the right, but not the obligation, to
register the Other Trademarks in any countries in the Territory for the Field
and to register the trademark "HySorb" in any countries in the Territory.
Hymedix shall cooperate with and assist ProCyte in the registrations for the
Trademarks where appropriate.  ProCyte may deduct from any royalties due under
Section 5 [CONFIDENTIAL TREATMENT REQUESTED] of its costs and expenses in
registering the Other Trademarks.

SECTION 18.   TERM AND TERMINATION

    18.1 TERM

This Agreement shall remain in full force and effect until the expiration of the
last to expire of any patents included in the Patent Rights or Joint
[CONFIDENTIAL TREATMENT REQUESTED] Patents.  Upon expiration of the term of this
Agreement, ProCyte shall have a fully paid-up, royalty-free, perpetual license
to use the Licensed Technology nonexclusively and to use the Trademarks
exclusively in the Territory for the Field.

    18.2 TERMINATION

(a) ProCyte shall have the right to terminate this Agreement at any time upon
sixty (60) days' prior written notice to Hymedix.  After such notice of
termination, ProCyte shall not have any obligation to make a milestone payment
due under Section 4 that accrues after such notice but before the effective date
of termination (i.e., for purposes of the milestone payments in Section 4, the
date of notice shall be deemed the date of termination).  In the event ProCyte
terminates this Agreement in accordance with this Section 18.2(a), ProCyte shall
grant to Hymedix, at its request, a royalty-free, nonexclusive, worldwide
license (with right to sublicense) to use any improvements to the Licensed
Technology made by ProCyte during the term of this Agreement that are only
usable in connection with the Licensed Technology and that are of no further
value to ProCyte; provided, however, that at the time of any sublicensing of
such improvements by Hymedix, Hymedix shall notify ProCyte and shall pay to
ProCyte its costs and expenses in making such improvements.  In addition,
ProCyte shall have the right to terminate any portion of its license hereunder
as to any patent included in the Patent Rights or Joint [CONFIDENTIAL TREATMENT
REQUESTED] Patents at any time upon sixty (60) days' prior written notice to
Hymedix.  The effective date for termination of this Agreement or any portion of
the license, as provided in this Section 18.2, shall be sixty (60) days after
written notice to Hymedix or such later date as may be specified in the written
notice to Hymedix.  Upon termination, neither party shall have any rights or
obligations under this Agreement or with respect to the portion of the
terminated license, as the case may be, except as provided in Section 19.7.

(b) If ProCyte fails to makes any payment due hereunder to Hymedix, Hymedix
shall have the right to terminate this Agreement fifteen (15) days after giving
ProCyte notice of such failure and Hymedix's intent to terminate unless ProCyte
makes such payment within such fifteen (15) day period.  If ProCyte commits any
material breach of this Agreement, Hymedix shall have the right to terminate
this Agreement ninety (90) days after giving ProCyte notice of such breach and
Hymedix's intent to terminate unless ProCyte has cured or commenced steps to
diligently cure the breach within such ninety (90) day period.  Upon
termination, any sublicensee who is not then in material breach shall have its
sublicense converted to a direct license from Hymedix under the terms and
conditions of this Agreement, as further limited and restricted by the terms of
the original sublicense.

(c) Either party may immediately terminate this Agreement effective upon giving
written notice of termination to the other party in the event that:

                                          31

<PAGE>

         (i)   the other party institutes any bankruptcy, insolvency,
               liquidation or receivership proceedings or proceedings for
               reorganization under bankruptcy or comparable laws concerning its
               operations;
         (ii)  the other party has a petition filed against it for any of the
               proceedings provided in (i) above, the effectiveness of which is
               not stayed or dismissed within sixty (60) days after the filing
               thereof; or
         (iii) the other party shall make a general assignment for the benefit
               of creditors.

    18.3 DISPOSITION OF PRODUCTS

Upon termination of this Agreement or a portion of the license, ProCyte (and its
Affiliates and sublicensees) shall have the right to complete any work in
progress and sell or otherwise dispose of any affected Product within the next
twelve (12) months; provided, however, that royalties and reports shall continue
to be due on any Net Sales of such Product in accordance with this Agreement.

                             STOCK ACQUISITION AGREEMENT

This STOCK ACQUISITION AGREEMENT (this "Agreement"), dated as of November 15,
1995, is entered into by and between PROCYTE CORPORATION, a Washington
corporation (the "Company"), and HYMEDIX INTERNATIONAL, INC., a Delaware
corporation ("Hymedix").
                                       RECITAL

1.     Contemporaneously with this Agreement, the Company and Hymedix are
entering into a License Agreement as of the date hereof (the "License
Agreement").

2.     In connection with the License Agreement, Hymedix desires to acquire,
and the Company desires to issue to Hymedix, shares of Common Stock of the
Company, upon the terms and conditions as set forth herein.

                                      AGREEMENT

NOW, THEREFORE, in consideration of the promises and mutual covenants contained
herein, the parties agree as follows:

1.     SHARES AND CONSIDERATION; ESCROW

In consideration of the rights of the Company and the obligations,
representations and warranties of Hymedix as set forth in the License Agreement,
the Company hereby agrees to issue and deliver to Hymedix 200,000 shares of
Common Stock of the Company (the "Shares"), subject to the terms of this
Agreement.  Promptly upon execution of this Agreement, the Company shall deliver
to Hymedix, or instruct its transfer agent to deliver to Hymedix, one or more
certificates representing the Shares (the "Certificates").  Upon receipt of the
Certificates, Hymedix shall deliver the Certificates and four executed
Assignments Separate from Certificate with respect to the shares represented by
the Certificates (the "Assignments") to the Company, both to be held by the
Company pursuant to the terms of this Agreement for a two-year vesting period. 
The Company will accept the Assignments only in the event that the Shares are
forfeited pursuant to Section 5 of this Agreement (such an event, a
"Forfeiture").  Upon the expiration of each six months during the two-year
vesting period, if no Forfeiture has occurred, the Company shall release 50,000
Shares represented by the Certificates and one of the Assignments and deliver
them to Hymedix.  Notwithstanding the foregoing, the Company may place stop-
transfer instructions with respect to any unvested portion of the Shares during
the two-year vesting period.

2.  REPRESENTATIONS AND WARRANTIES OF HYMEDIX

Hymedix hereby represents and warrants to the Company as of the date of this
Agreement as follows:

    2.1  ABILITY TO BEAR RISK 

Hymedix is in a financial position to hold the Common Stock and is able to bear
the economic risk and withstand a complete loss of its investment in the Shares.

    2.2  HIGH DEGREE OF RISK

HYMEDIX RECOGNIZES THAT THE SHARES AS AN INVESTMENT INVOLVE A HIGH DEGREE OF
RISK.  Hymedix is aware that the Company has not been profitable in the past. 
Hymedix recognizes that the Company is in the research and development stage and
has not yet developed a marketable product and that there can be no assurance
that the Company will be able to develop a marketable product or that such
product will be accepted in the marketplace.  There can be no 


                                          45

<PAGE>

assurance that the Company will be able to obtain its projected goals and the
Company may need significant additional capital to be successful, which capital
may not be readily available when and as needed.

    2.3  PROFESSIONAL ADVICE

Hymedix has obtained, to the extent it deems necessary, its own professional
advice with respect to the risks inherent in the investment in the Shares, the
condition of the Company and the suitability of the investment in the Shares in
light of Hymedix's financial condition and investment needs.

    2.4  SOPHISTICATION

Hymedix, either alone or with the assistance of its professional advisor, is a
sophisticated investor, is able to fend for itself in the transactions
contemplated by this Agreement, and has such knowledge and experience in
financial and business matters that it is capable of evaluating the merits and
risks of the investment in the Shares.

    2.5  ACCESS TO INFORMATION

Hymedix has been given access to full and complete information regarding the
Company, including, in particular, the Company's annual report and proxy
statements for the last two fiscal years, its reports on Forms 10-K, 10-Q and 8-
K for the last two fiscal years, its reports on Form 10-Q for the first three
quarters of the current fiscal year and information regarding the current
financial condition of the Company and the risks associated therewith, and has
utilized such access to its satisfaction for the purpose of obtaining
information about the Company; particularly, Hymedix has either attended or been
given reasonable opportunity to attend a meeting with representatives of the
Company for the purpose of asking questions of, and receiving answers from, such
representatives concerning the terms and conditions of the issuance of the
Shares and to obtain any additional information, to the extent reasonably
available, necessary to verify the accuracy of information provided about the
Company.

    2.6  PURCHASE ENTIRELY FOR OWN ACCOUNT

The Shares will be acquired for investment for Hymedix's own account, not as a
nominee or agent, and not with a view to the distribution of any part thereof;
Hymedix has no present intention of selling, granting any participation in or
otherwise distributing the same in a manner contrary to the Securities Act of
1933, as amended (the "Act"), or any applicable state securities or Blue Sky
law, or entering into any agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person, with
respect to any of the Shares.

    2.7  DUE DILIGENCE

Hymedix has been solely responsible for its own due diligence investigation of
the Company and the Company's business, and its analysis of the merits and risks
of the investment made pursuant to this Agreement, and is not relying on anyone
else's analysis or investigation of the Company, its business or the merits and
risks of the Shares other than professionals employed specifically by Hymedix to
assist Hymedix.  In taking any action or performing any role relative to the
arranging of the investment being made pursuant to this Agreement, Hymedix has
acted solely in its own interest and not in that of any other person, and no
other person has acted as an agent or fiduciary for Hymedix.

    2.8  RESTRICTED SECURITIES

Hymedix realizes that the issuance of the Shares hereunder has not been
registered under the Act, the Shares are characterized under the Act as
"restricted securities", and, therefore, the Shares cannot be sold or
transferred unless they are subsequently registered under the Act or an
exemption from such registration is available.  Hymedix's financial condition is
such that it is not likely that it will 

                                          46

<PAGE>

be necessary to dispose of any of the Shares in the foreseeable future.  In this
connection, Hymedix represents that it is familiar with Rule 144 of the
Securities and Exchange Commission (the "SEC"), as presently in effect, and
understands the resale limitations imposed thereby and by the Act.

    2.9  EXEMPTION RELIANCE

Hymedix has been advised that the Shares are not being registered under the Act
or the applicable state securities laws, but are being offered and sold pursuant
to exemptions from such laws, and that the Company's reliance upon such
exemptions is predicated in part on Hymedix's representations contained herein. 
Hymedix represents that it has not been organized for the specific purpose of
investing in the Shares.

    2.10 RESIDENCY

For purposes of the application of state securities laws, Hymedix represents
that it is domiciled in the State of New Jersey.


    2.11 LEGENDS

(a) It is understood that the Certificates evidencing the Shares will bear a
legend as follows:

"The securities evidenced by this certificate have not been registered under the
Securities Act of 1933, as amended, of the United States of America (the "Act"),
or the securities laws of any state of the United States of America, and no
interest in such securities may be sold, distributed, assigned, offered, pledged
or otherwise transferred, directly or indirectly, in the United States of
America, its territories or possessions, or to a citizen, national, resident or
entity organized or chartered under the laws of the United States of America,
its territories or possessions, unless (i) there is an effective registration
statement under the Act and applicable state securities laws covering any such
transaction, (ii) this corporation receives an opinion of legal counsel for the
holder of these securities satisfactory to this corporation stating that such
transaction is exempt from registration under the Act and applicable state laws,
or (iii) this corporation otherwise satisfies itself that such transaction is
exempt from registration.

The securities evidenced by this certificate are subject to certain resale
restrictions as set forth in a stock acquisition agreement between the Company
and the registered holder, a copy of which is on file at the principle office of
the Company."

(b) In addition, until the Shares become vested in Hymedix pursuant to the
provisions of Section 5 of this Agreement, the Certificates evidencing the
Shares will bear the following legend:

"The securities represented by this certificate are subject to forfeiture
pursuant to the terms of a Stock Acquisition Agreement dated as of November 15,
1995 between this corporation and Hymedix International, Inc., a copy of which
is available upon request at the principal office of this corporation."

    2.12 ACKNOWLEDGMENT

HYMEDIX, BY EXECUTION OF THIS AGREEMENT, ACKNOWLEDGES THAT IT UNDERSTANDS THAT
THE COMPANY IS RELYING UPON THE ACCURACY AND COMPLETENESS OF ITS REPRESENTATIONS
AND WARRANTIES SET FORTH IN THIS SECTION 2 IN DECIDING WHETHER TO ISSUE SHARES
OF COMMON STOCK TO HYMEDIX AND IN COMPLYING WITH THE COMPANY'S OBLIGATIONS UNDER
APPLICABLE SECURITIES LAWS.

3.  RESTRICTIONS ON TRANSFER

   3.1   COMPLIANCE WITH SECURITIES LAWS

Without in any way limiting the representations set forth above and subject to
the forfeiture provisions set forth in Section 5 of this Agreement, Hymedix
further agrees not to make any disposition of all or any portion of the Shares
unless and until:

                                          47

<PAGE>

               (a)     There is then in effect a registration statement under

               (b)(i)  Hymedix shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition 10 days prior to said
disposition and (ii) if reasonably requested by the Company, Hymedix shall have

Company, that such disposition will not require registration of such shares
under the Act; or

               (c)(i)  Hymedix shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition at least 10 days prior to
said disposition and (ii) the Company shall have otherwise been satisfied that
such proposed disposition complies in all respects with SEC Rule 144 or any
successor rule providing a safe harbor for such disposition without
registration.

   3.2 TRANSFEREE CONSIDERATIONS

In addition to the foregoing provisions of Section 3.1 above, Hymedix agrees
that:

               (a)     Hymedix shall notify the Company of any proposed
disposition of all or any portion of the Shares and shall furnish the Company
with a detailed statement of the circumstances surrounding the proposed
disposition at least 10 days prior to said disposition; and

               (b)     Hymedix shall provide the Company or its agent an
opportunity to arrange the private sale to one or more parties of the Shares
proposed to be transferred and shall cooperate fully with the Company or such
agent in such process; if, prior to the later of (i) 10 days after the date the
notice referred to in paragraph (a) is received by the Company and (ii) the
proposed closing date of the transfer, the Company or its agent identifies a
party or parties who agree or offer in writing to purchase the Shares proposed
to be transferred, Hymedix shall give due consideration to such offer.

4.     REGISTRATION RIGHTS

The Registration Rights attached hereto as Exhibit A are hereby incorporated
into and made a part of this Agreement as if set forth herein; provided,
however, that no portion of the Shares that are unvested pursuant to the terms
of Section 5 of this Agreement may be sold pursuant to any registration provided
for in the Registration Rights.

5.     FORFEITURE OF SHARES

(a)    During the period ending two years from the date of this Agreement,
Hymedix shall forfeit any unvested portion of the Shares and the Company will
accept the Assignment of such Shares if:

or this Agreement (a "Material Breach") and Hymedix has not cured such Material
Breach within 

                                          48

AVAILABLE.

                                 REGISTRATION RIGHTS
    1.   DEFINITIONS.

For purposes of this Agreement, the following terms not otherwise defined shall
have the following respective meanings:

          (a) The term "register," "registered" and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Act, and the declaration or ordering of
effectiveness of such registration statement or document;

          (b) The term "Registrable Securities" means (i) the Shares held by
Holders (as defined below), and (ii) any Common Stock of the Company issued as
(or issuable upon the conversion or exercise of any warrant, right or other
security which is issued as) a dividend or other distribution with respect to,
or in exchange for or in replacement of, the Shares held by Holders, excluding
in all cases, however, any Common Stock sold by a person in a transaction in
which its rights under this Agreement are not assigned and any Common Stock that
is, at the time of registration, transferable by the holder thereof in a single
brokerage transaction under the provisions of Rule 144 promulgated under the
Act, or any successor to such Rule; and

          (c) The term "Holder" means any person owning or having the right to
acquire Registrable Securities who is a party to this Agreement as of the date
hereof and any assignee thereof in accordance with Section 8 hereof.

    2.   COMPANY REGISTRATION.

For the one year period beginning on the second anniversary of this Agreement
and ending on the third anniversary of this Agreement, if (but without any
obligation to do so) the Company proposes to register (including for this
purpose a registration effected by the Company for shareholders other than the
Holders) any shares of Common Stock under the Act in connection with the public
offering of such securities solely for cash (other than a registration relating
solely to the sale of securities to participants in a Company stock plan, or a
registration on any form that does not include substantially the same
information as would be required to be included in a registration statement
covering the sale of the Registrable Securities), the Company shall, at such
time, promptly give each Holder written notice of such registration.  Upon the
written request of each Holder given within 20 days after mailing of such notice
by the Company, the Company shall, subject to the provisions of Section 5
hereof, use its best efforts to cause to be registered under the Act all of the
Registrable Securities that each such Holder has requested to be registered.  In
the event that the Company decides for any reason not to complete the
registration of shares of Common Stock other than the Registrable Securities,
the Company shall have no obligation under this Section 2 to continue with the
registration of the Registrable Securities.  Any request pursuant to this
Section 2 to register Registrable Securities as part of an underwritten public
offering of Common Stock shall specify that such Registrable Securities are to
be included in the underwriting on the same terms and conditions as the shares
of Common Stock otherwise being sold through underwriters under such
registration.

    3.   FURNISH INFORMATION.

It shall be a condition precedent to the obligations of the Company to take any
action pursuant to this Agreement that the selling Holders shall furnish to the
Company such information regarding themselves, the Registrable Securities held
by them and the intended method of disposition of such securities as shall be
reasonably required to effect the registration of their Registrable Securities
and to execute such documents in connection with such registration as the
Company may reasonably request.

    4.   EXPENSES OF REGISTRATION.

In connection with any registration pursuant to this Agreement, the Company
shall be responsible for the payment of all expenses of the registration, with
the exception of underwriting commissions and discounts which shall be paid by
the Company, the Holders and any other selling securityholders in 

                                          51

<PAGE>


proportion to the aggregate value of the securities offered for sale by each of
them.  The expenses to be paid by the Company shall include, without limitation,
all SEC, blue sky, stock exchange and NASD registration and filing fees,
printing and duplicating expenses, fees and disbursements of its counsel and
accountants, blue sky legal fees and disbursements, transfer agents' and
registrars' fees and expenses, fees and expenses of any experts used in
connection with the registration, and any fees and expenses of underwriters
customarily paid by issuers or sellers of securities, but excluding any
underwriting commissions and discounts.

    5.   UNDERWRITING REQUIREMENTS.

The Company shall not be required under Section 2 hereof to include any of the
Holders' securities in an underwritten offering of the Company's securities
unless such Holders accept the terms of the underwriting as agreed upon between
the Company and the underwriters selected by it.  If the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities that the underwriters
reasonably believe compatible with the success of the offering, then the Company
shall be required to include in the offering only that number of such
securities, including Registrable Securities, which the underwriters believe
will not jeopardize the success of the offering.  The securities of selling
shareholders to be included in the registration in the event of such a reduction
shall be apportioned pro rata among the selling Holders according to the total
amount of securities requested to be sold in such registration by such Holders
and then pro rata among any other selling shareholders (if any) according to the
total amount of securities otherwise entitled to be included therein owned by
each such other selling shareholder, or in such other proportions as shall
mutually be agreed to by such selling shareholders.

    6.   DELAY OF REGISTRATION

No Holder shall have any right to obtain or seek an injunction restraining or
otherwise delaying any registration of the Company as the result of any
controversy that might arise with respect to the interpretation or
implementation of this Agreement.

    7.   INDEMNIFICATION.

In the event any Registrable Securities are included in a registration statement
under this Agreement:

         (a)  To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, the partners, officers, agents, employees and
directors of each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the Securities Exchange Act of 1934, as amended (the
"1934 Act"), against any losses, claims, damages or liabilities (joint or
several) to which they may become subject under the Act, the 1934 Act or other
federal or state law, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively, a "Violation"): (i) any
statement or alleged statement of a material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein, or any amendments or supplements thereto, untrue in light of the
circumstances under which they were made, (ii) the omission or alleged omission
to state therein a material fact required to be stated therein, or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, or (iii) any violation or alleged violation by the Company
of the Act, the 1934 Act, any state securities law or any rule or regulation
promulgated under the Act, the 1934 Act or any state securities law.  The
Company shall reimburse each such Holder, partner, officer, agent, employee or
director, underwriter or controlling person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the
indemnity agreement contained in this Section 7(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company, which consent shall
not be unreasonably withheld, nor shall the Company be liable in any such case
for any such loss, claim, damage, liability or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information 


                                          52

furnished expressly for use in connection with such registration by, or on
behalf of, any such Holder, underwriter or controlling person.

         (b)  To the extent permitted by law, each selling Holder will
indemnify and hold harmless the Company, each of its officers, directors, agents
or employees, each person, if any, who controls the Company within the meaning
of the Act, any underwriter and any other Holder selling securities in such
registration statement or any of its partners, officers, directors, agents or
employees or any person who controls such Holder, against any losses, claims,
damages or liabilities (joint or several) to which the Company or any such
officer, director, agent, employee, controlling person, or underwriter, or other
such Holder or its partner, officer, director, agent, employee or controlling
person may become subject, under the Act, the 1934 Act or other federal or state
law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon
and in conformity with written information furnished by, or on behalf of, such
Holder expressly for use in connection with such registration.  Each such Holder
will reimburse any legal or other expenses reasonably incurred by the Company or
any such partner, officer, director, agent, employee, controlling person,
underwriter or other such Holder, partner, officer, director, agent, employee or
controlling person in connection with investigating or defending any such loss,
claim, damage, liability or action; PROVIDED, HOWEVER, that the indemnity
agreement contained in this Section 7(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the indemnifying Holder, which
consent shall not be unreasonably withheld.

         (c)  Promptly after receipt by an indemnified party under this Section
7 of notice of the commencement of any action (including any governmental
action), such indemnified party shall, if a claim in respect thereof is to be
made against any indemnifying party under this Section 7, deliver to the
indemnifying party a written notice of the commencement thereof, and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly notified, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if, in the reasonable opinion of counsel for the
indemnifying party, representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or
potential differing interests between such indemnified party and any other party
represented by such counsel in such proceeding.  The failure to deliver written
notice to the indemnifying party within a reasonable period of time of the
commencement of any such action shall relieve such indemnifying party of any
liability to the indemnified party under this Section 7 to the extent
prejudicial to its ability to defend such action, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 7.

    8.   TRANSFER OF REGISTRATION RIGHTS.

The rights of a Holder under this Agreement may be assigned or transferred in
connection with any transfer of Shares by the Holder, provided that (a) the
transferee, upon completion of the transfer, holds at least 50,000 of the
Registrable Securities, (b) the Company is given prior notice of such transfer
of rights, and (c) such transferee agrees in writing to be bound by this
Agreement.

    9.   "MARKET STAND-OFF" AGREEMENT.

For five years from the date of this Agreement, each Holder hereby agrees that
such Holder shall not, to the extent requested by the Company and an underwriter
of Common Stock (or other securities) of the Company, sell or otherwise transfer
or dispose of any Registrable Securities for 180 days following the effective
date of a registration statement of the Company filed under the Act in
connection with an offering of the Company's Common Stock; PROVIDED, HOWEVER,
that all officers and directors of the Company and all other persons with
registration rights (whether or not pursuant to this Agreement) enter into
similar agreements.

                                          53

<PAGE>

In order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of the Holders (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

    10.  AMENDMENTS AND WAIVERS.

Any term of this Agreement may be amended and the observance of any term may be
waived (either generally or in a particular instance and either retroactively or
prospectively) only with the written consent of the Company and the holders of
at least 60% of the aggregate of the shares of Common Stock that are Registrable
Securities.

                PROCYTE ACQUIRES FIVE FDA-CLEARED WOUND CARE PRODUCTS

                     PROPRIETARY POLYMER TECHNOLOGY FORMS BASIS 
                  FOR EARLY PRODUCT LAUNCHES IN FAST-GROWING SECTOR

    (Kirkland, Washington) -- PR Newswire -- ProCyte Corporation (Nasdaq/NMS:
PRCY) today said it has acquired from HYMEDIX International, Inc. (Bulletin
Board: HYMX) the worldwide rights outside of Asia to five wound care products
that have received market clearance from the  U.S. Food and Drug Administration,
broadening the company's planned entry into the $300 million market for moist
wound dressings.

    The products include proprietary transparent thin film wound dressings,
aquagel sheet dressings, exudate absorbers and wound moisturizers, all based on
a multi-block copolymer structure that is especially well-suited for wound care
applications, including chronic and acute wounds, burns and surgical wounds,
according to ProCyte.

    The company said that the newly licensed products compliment its
internally-developed Iamin-Registered Trademark- gel wound dressing, for which
FDA clearance to market is pending under the 510(k) pre-market notification
guidelines.

    ProCyte said it expects the first of its wound care products to be
available to long-term care, hospital and home healthcare professionals by mid-
1996, following equipment scale-up and design and validation of improved
manufacturing processes at its Redmond, WA commercial manufacturing plant.

    The facility was commissioned last year and will require certain equipment
additions for the initial product launch.  

    Although specific terms were not disclosed, ProCyte said the agreement with
HYMEDIX calls for an upfront cash and common stock payment to HYMEDIX, plus
future milestone payments of additional cash and royalties.

    "Our intent was to quickly establish an innovative and medically-responsive
wound care portfolio with a broad range of essentially market-ready products,"
said Joseph Ashley, ProCyte's president and chief executive officer.  "This
unique polymer technology gives us the initial 


                                          57

<PAGE>

marketing capability for a serious wound care products business with near-term
revenue potential.  We can then leverage this with new product developments out
of our own labs."

    ProCyte has considerable research and development experience in the field
of wound care, and has helped to pioneer the clinical assessment and treatment
of wounds.

    The U.S. market for moist wound dressings, which include the polymer-based
products ProCyte acquired, is expected to reach $500 million in industry-wide
sales by 1999.  Industry sources say the market growth for moist wound dressings
and all other wound care products and systems is being driven by an increasing
incidence of wounds associated with advanced age, during which surgeries and
chronic wounds tend to occur more frequently.

    The centerpiece for ProCyte's newly-acquired products is a versatile
polymer technology, called HYPAN-Registered Trademark-.  HYPAN-Registered
Trademark- polymers may be manufactured by a patented method to provide a
uniquely variable number of structural aquagels, useful in the construction of
synthetic moist wound dressings and related products.  

    ProCyte also has the worldwide rights outside of Asia for all future wound
care applications of the HYPAN-Registered Trademark- technology for synthetic
moist wound dressings and related products.

    As part of its agreement with HYMEDIX, ProCyte also gained exclusive
worldwide rights for the drug delivery applications of the HYPAN-Registered
Trademark- technology for wound care.  ProCyte plans to continue its research
and development efforts in wound treatment and healing, and to study the drug
delivery aspects of the technology for enhanced delivery of antibiotics, 
anti-infectives and other compounds to wounds.

    HYPAN-Registered Trademark- polymers are synthetic materials that ProCyte
believes can be manufactured in a cost-effective manner.  HYPAN-Registered
Trademark- polymers are also believed to provide maximum performance at low
concentrations, to have excellent biocompatibility profiles and to be both
stable and sterilizable.  The remarkable structural flexibility of these
aquagels is expected to make them ideally suited to broad-based applications in
wound management and treatment, particularly since they address the breadth of
chronic and acute wounds.

    HYMEDIX is a development-stage company based in New Jersey.  The company is
actively commercializing its polymer-based BIONIQ-TM- line of personal care
moisturizing creams, which have recently been introduced through direct response
television. HYMEDIX currently has research and development  contracts in place
for other medical products and drug delivery applications of its
HYPAN-Registered Trademark- polymers outside the field of wound care.

     ProCyte is a development stage pharmaceutical company.  It has been 
actively pursuing a threefold corporate strategy, including development of its 
own proprietary copper-based compounds, providing contract manufacturing, and
seeking to acquire late-stage products or technology.  ProCyte has three 
copper-based compounds in clinical development, including drug candidates for 
treatment of inflammatory bowel disease and hair growth.
