duly authorized, executed and delivered by the Company. The Company's execution,
delivery and performance of this Agreement, the Bonds and each Document will not
violate (i) any law, rule or regulation applicable to the Company or any of its
subsidiaries or (ii) the Certificate of Incorporation or Bylaws of the Company
or any of its subsidiaries or (iii) any provision of any indenture, mortgage,
agreement, contract or other instrument to which the Company or any of its

any of their properties or assets is bound as of the date hereof, or result in a
breach of or constitute (upon notice or lapse of time or both) a default under
any such indenture, mortgage, agreement, contract or other instrument or result
in the creation or imposition of any lien, security interest, mortgage, pledge,
charge or other encumbrance upon any properties or assets of the Company or any
of its subsidiaries, except, in the case of such clause (iii), where such
violation, breach or default would not have a material adverse effect on the
business, properties, prospects, condition (financial or otherwise), net worth
or results of operations of the Company and its subsidiaries taken as a whole (a
"Material Adverse Effect"). Upon their execution and delivery (assuming the
valid execution thereof by the respective parties thereto other than the
Company), this Agreement, the Documents and the Bonds will constitute valid and
binding obligations of the Company, enforceable in accordance with their
respective terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
creditors' and contracting parties' rights generally and except as
enforceability may be subject to general principles of equity (regardless of

affecting creditors' and contracting parties rights generally and except as
enforceability may be subject to general principles of equity (regardless of
whether such enforceability is considered in a proceeding at equity or at law).
Upon issuance, the Series D Preferred Stock, Warrants and Underlying Common
Stock will be duly authorized and validly issued and, upon payment therefor,
will be non-assessable.

any court or governmental agency or body, domestic or foreign, now pending, or,
to the knowledge of the Company, threatened against or affecting the Company or
any of its subsidiaries which might result in any material adverse change in the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of the Company and its subsidiaries, taken as a whole, or
which might materially and adversely affect their property or assets or which
might materially and adversely affect the consummation of this Agreement and the
other Documents. All pending legal or governmental proceedings to which the
Company or any of its subsidiaries is a party or of which any of their property
or assets is the subject, including ordinary routine litigation incidental to
the business, are, considered in the aggregate, not material to the business of
the Company and its subsidiaries.

Act Reports, the Company has not incurred any material liabilities or
obligations, direct or contingent, nor has the Company or any of its
subsidiaries purchased any of their outstanding capital stock, nor paid or

increase in the consolidated short-term borrowings (other than in the ordinary
course of business) of the Company or any material adverse change to the
business, properties, assets, net worth, condition (financial or other), results
of operations or prospects of the Company and its subsidiaries, taken as a
whole.

         4.8. Legal Opinion. Prior to closing, Hedger & Hedger, counsel to the
Company, will deliver its legal opinion to the Company in the form of Appendix
II hereto and stating that each of the Purchasers may rely thereon as though

Bond), issue to each converting Purchaser a certificate or certificates
representing the number of securities comprising the Units to which such
Purchaser is entitled which certificates shall be legended as provided in the

Re:  Offer and Sale of Convertible Bonds

Members of the Board:

We are counsel to Derma Sciences, Inc. (the "Company") in connection with the
offer and sale of those certain convertible bonds due December 31, 2000 in the
aggregate principal amount of $750,000 (the "Bonds"). We have examined the
originals, or certified, conformed or reproduction copies, of all records,
agreements, instruments and documents relative to the Bonds as we have deemed
relevant or necessary as the basis for the opinion hereinafter expressed. Our
examination included review of the purchase agreement, convertible bonds,
security agreement, form of preferred stock certificate, form of certificate of
preferences and rights of Series D Convertible Preferred Stock, form of warrant
agreement, registration rights agreement, consents of preferred stockholders and
certificate of compliance ("Document(s)"). In all such examinations, we have
assumed the genuineness of all signatures on original or certified copies and
the conformity to original or certified copies of all copies submitted to us as
conformed or reproduction copies. As to various questions of fact relevant to
our opinion, we have relied upon, and assumed the accuracy of, certificates and
oral or written statements and other information of or from public officials,
officers or representatives of the Company and others.

Based upon the foregoing, we are of opinion as follows:

         1. The Company and its subsidiaries are corporations duly organized,
validly existing and in good standing under the laws of their jurisdictions of
incorporation and have all requisite corporate power and authority to conduct
their business as currently conducted.

         2. As of the date hereof, the authorized capital stock of the Company
consists of: (a) 30,000,000 shares of Common Stock of which 1,325,938 shares are
outstanding, (b) 1,750,000 shares of Series A Convertible Preferred Stock of
which 272,500 shares are outstanding, (c)

<PAGE>

Board of Directors
December   , 1999
Page 2


3,333,340 shares of Series B Convertible Preferred Stock of which 666,668 shares
are outstanding, (d) 6,666,660 shares of undesignated preferred stock of which
none are outstanding and (e) $875 aggregate principal amount of convertible
bonds due August 15, 2000.

         3. Each of the Documents, upon their execution and delivery (assuming
the valid execution thereof by the respective parties thereto other than the
Company), will constitute valid and binding obligations of the Company,
enforceable in accordance with their respective terms, except as enforceability
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium
or similar laws affecting creditors' rights generally and except as
enforceability may be subject to general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).
Upon payment therefor, the Bonds, together with all securities into which the
Bonds may be converted, will be validly issued and nonassessable.

         4. The Company has full corporate power and authority to enter into
each Document. Each Document has been duly authorized, executed and delivered by
the Company. The Company's execution, delivery and performance under each
Document will not violate (i) any statute, rule or regulation applicable to the
Company or its subsidiaries, (ii) to the best of our knowledge, any order,
judgment, ruling or decree of any court or any governmental, regulatory or
administrative body applicable to the Company or any of its subsidiaries, (iii)
the Articles of Incorporation or Bylaws of the Company, or (iv) to our
knowledge, any provision of any indenture, mortgage, agreement, contract or
other instrument to which the Company or any of its subsidiaries is bound or
constitute (upon notice or lapse of time or both) a default under any thereof,
or result in the creation or imposition of any lien, security interest,
mortgage, pledge, charge or other encumbrance upon any properties or assets of
the Company or any of its subsidiaries, except in the case of the foregoing
clauses (i), (ii) and (iv) for those violations, breaches or defaults which
would not, singly or in the aggregate, have a material adverse effect upon the
Company's operations, prospects or financial condition ("Material Adverse
Effect").

         5. To our knowledge (without independent investigation), there is no
action, suit or proceeding before or by any court or governmental agency or
body, domestic or foreign, now pending, or threatened, against or affecting the
Company or any of its subsidiaries which might, singly or in the aggregate, have
a Material Adverse Effect, or which might materially and adversely affect the
consummation of the Documents; to our knowledge (without independent
investigation) all pending legal or governmental proceedings to which the
Company or any of its subsidiaries is a party or of which any of their property
or assets is the subject, including ordinary routine litigation incidental to
the business, are, considered in the aggregate, not material to the business of
the Company and its subsidiaries.

         6. Except for compliance with Rule 506 of Regulation D under the
Securities Act of 1933 and applicable state securities laws in connection with
the offer and sale of the Bonds, and except

<PAGE>

Board of Directors

for compliance with applicable federal and state securities laws in connection
with the resale by purchasers of the Bonds of the Underlying Common Stock (as
defined in the Bonds), no consent, approval, authorization, order, registration,
filing, qualification, license or permit of or with any court or any public,
governmental, or regulatory agency or body having jurisdiction over the Company
or any of its subsidiaries or any of their respective properties or assets is
required for the execution, delivery and performance under the Documents or the
consummation of the transactions contemplated hereby.

                               _________________

We hereby authorize the Purchasers to rely upon this opinion as if it were
addressed individually to each Purchaser.

Very truly yours,

                     CONVERTIBLE BOND DUE DECEMBER 31, 2000

NO. CBB-4                                                        U.S. $50,000.00

         Derma Sciences, Inc., a corporation duly incorporated and existing
under the laws of the Commonwealth of Pennsylvania (the "Company"), for value
received hereby promises to pay to MED-TEC INVESTORS, LLC, 777 Alexander Road,
Princeton, New Jersey 08540 (the "Bondholder"), or registered assigns, the
principal sum of FIFTY THOUSAND United States Dollars on December 31, 2000 (the
"Stated Maturity"), or earlier, together with interest on the principal sum at
an annual rate equal to the Prime Rate. "Prime Rate" under the Bond is the prime
commercial lending rate published in The Wall Street Journal on the 1st day (or,
if the 1st day is not a day on which The Wall Street Journal is published, the
next preceding day of publication) of the month in which such interest accrues.
If more than one prime rate is so published, the Prime Rate shall be the average
of such prime rates. If no such prime rate is so published, the Prime Rate shall
be the prime commercial lending rate then in effect at Morgan Guaranty Trust
Company. Interest under the Bond shall accrue at the aforesaid Prime Rate,
compounded monthly, and shall be payable quarterly as specified below.

         The Company shall make three (3) interest only payments under the Bond
which payments shall be due on or before each of April 1, 2000, July 1, 2000 and
October 1, 2000. The Company shall make a final payment consisting of the entire
balance of principal and accrued but unpaid interest on or before December 31,
2000. If any payment is due on a Saturday or Sunday, or on any national holiday
on which commercial banks in New York, New York are not open for normal
business, such payment shall be made on the next succeeding business day. At the
option of the Bondholder, accrued interest under the Bond for any given calendar
quarter shall be satisfied either by: (1) cash payment on the first business day
following the end of the calendar quarter with respect to which the subject
interest accrued, or (2) capitalization of the accrued interest into the
principal of the Bond.

         All payments under the Bond shall be made to the Bondholder, in
immediately available funds, at its address provided above or to such account as
the Bondholder shall designate in

                                       1

<PAGE>


writing. All or any part of the unpaid principal balance or accrued but unpaid
interest may be prepaid by the Company at any time, and from time to time,
without premium or penalty. Any prepayments shall be paid ratably to each
Bondholder and shall be applied first to accrued but unpaid interest and then to
the unpaid principal balance.

         The Bond is one of a series of bonds issued and to be issued by the
Company aggregating not greater than $750,000 in principal amount, maturing
December 31, 2000 and being otherwise of like tenor and effect (the "Bonds").
All Bonds are, as to both principal and interest, issued under and equally
secured by a security agreement of even date herewith (the "Security Agreement")
whereby the Company has mortgaged and pledged certain of its property now owned
and hereafter acquired to the holders of the Bonds ("Bondholders"). The Bonds
shall share pro rata in the security created by, and described in, the Security
Agreement ("Security"), subject to the prior rights in the Security of the
holders of the Company's $875,000 aggregate principal amount convertible bonds
due August 15, 2000, irrespective of the dates or order of filing of the various
Security Agreements, or the dates or order of filing of associated Forms UCC-1
or any other indicia of priority.

         The Bondholder, at any time prior to the Stated Maturity and at any
time thereafter so long as any portion of the principal or interest due
hereunder remains unpaid, may, at its option, convert all or any portion of the
unpaid principal and accrued interest of the Bond into Units in accordance with
the Terms and Conditions of the Bonds attached hereto.

         UPON THE OCCURRENCE OF AN EVENT OF DEFAULT HEREUNDER, THE COMPANY DOES
HEREBY APPOINT AND EMPOWER THE PROTHONOTARY OR ANY ATTORNEY OF ANY COURT OF
RECORD WITHIN THE COMMONWEALTH OF PENNSYLVANIA TO APPEAR FOR THE COMPANY AND
CONFESS JUDGMENT OR JUDGMENTS AGAINST THE COMPANY IN ANY COURT OF RECORD WITHIN
THE COMMONWEALTH OF PENNSYLVANIA AT ANY TIME AFTER THE DATE OF THIS NOTE IN
FAVOR OF THE BONDHOLDER, ITS SUCCESSORS AND ASSIGNS, FOR THE UNPAID PRINCIPAL
BALANCE OF THE BOND AND ALL INTEREST ACCRUED HEREON, TOGETHER WITH COSTS OF SUIT
AND A REASONABLE ATTORNEY'S COMMISSION FOR COLLECTON OF SUCH SUMS, AND THE
COMPANY HEREBY FOREVER WAIVES AND RELEASES ANY AND ALL ERRORS IN SAID
PROCEEDINGS

                                       2

<PAGE>


AND WAIVES STAY OF EXECUTION AND STAY, CONTINUANCE OR ADJOURNMENT OF SALE ON
EXECUTION. THE AUTHORITY AND POWER TO APPEAR FOR AND ENTER JUDGMENT AGAINST THE
COMPANY SHALL NOT BE EXHAUSTED BY ONE OR MORE EXERCISES THEREOF, AND MAY BE
EXERCISED FROM TIME TO TIME AND AS OFTEN AS THE BONDHOLDER OR ITS SUCCESSORS AND
ASSIGNS SHALL DEEM NECESSARY OR DESIRABLE.

         Reference is hereby made to the further provisions of the Bond set
forth under the Terms and Conditions of the Bonds attached hereto which further
provisions shall for all purposes have the same effect as if set forth at this
place.

         IN WITNESS WHEREOF, the Company has caused the Bond to be duly executed
by the signature of its President and Chief Executive Officer as attested by its
Vice President and Chief Financial Officer.

Dated:  December   , 1999

<PAGE>


                        TERMS AND CONDITIONS OF THE BONDS

1.       GENERAL.

         (a) The Bonds are issuable, without coupons, in denominations of U.S.
$20 and multiples thereof. The Bonds, and transfers thereof, shall be in
registered form as provided in Section 6 hereof. The registered holder of a Bond
shall (to the fullest extent permitted by applicable law) be treated at all
times, by all persons and for all purposes as the absolute owner of such Bond
regardless of any notice of ownership, theft or loss or of any writing thereon.

         (b) The Bonds are direct obligations of the Company. Without the
approval of the Bondholders, or except as otherwise provided herein, the Company
may not incur or issue any other indebtedness or bonds which rank senior or pari
passu to the Bonds.

         (c) The Company shall, within seven (7) business days of the Conversion
Notification Date (defined below), amend its Articles of Incorporation pursuant
to those certain Purchase Agreements of even date herewith by and between the
Company and the Bondholders ("Purchase Agreements") to authorize the issuance of
the shares of Series D Preferred Stock, $.01 par value, set forth in the
Purchase Agreement ("Series D Preferred Stock"). The Company represents and
warrants that it has reserved for issuance, and covenants that it shall continue
to reserve for issuance, that number of shares of Underlying Common Stock
(defined below) required to be issued upon the conversion of the Series D
Preferred Stock and exercise of the Warrants.

         (d) On the Conversion Date (defined below) the Bonds shall convert into
units (the "Units") each of which consists of one share of Series D Convertible
Preferred Stock and one Warrant to purchase one share of Common Stock (defined
below) at a price equal to the Unit Purchase Price (defined below). Each Bond
shall convert into such number of Units as shall result by dividing the
principal amount of the Bond by the Unit Purchase Price.

         (e) The Company shall file within 60 days of the Conversion Date, and
use its best efforts to cause to become effective, a registration statement (the
"Registration Statement") covering the resale of the shares of the Underlying
Common Stock.

         (f) Upon the earlier of final payment by the Company of all principal
and interest due under the Bond or the Stated Maturity, all Warrants which would
otherwise have been issuable to the Bondholder had it converted the Bond into
Units shall thereupon be issued to the Bondholder; provided, however, such
issuance shall not impair the right of the Bondholder to enforce payment of the
balance due, if any, under the Bond.

2.       DEFINITIONS.

         (a) The "Conversion Notification Date" under the Bond is the date the
Conversion Notice set forth at page 8 hereof is received by the Company.

         (b) The "Conversion Date" under the Bond is the later of the Conversion
Notification Date or the date of the filing with the Department of State,
Commonwealth of Pennsylvania, of

                                       1

<PAGE>


the amendment to the Company's Articles of Incorporation to authorize the
issuance of the Series D Preferred Stock.

         (c) The "Unit Purchase Price" shall be $1.0125.

         (d) The "Underlying Common Stock" are shares of the Company's common
stock, $.01 par value per share ("Common Stock"), issuable upon conversion of
the Series D Preferred Stock and exercise of the Warrants.

3.       CONVERSION.

         (a) On the Conversion Date the Bonds, together with accrued interest
thereon, that are the subject of a Conversion Notice shall automatically and
without any further action on the part of the Bondholder be converted into
Units, and the Bonds so converted shall thereafter be void and of no force or
effect.

         (b) Any fractional Units otherwise issuable by the Company upon
conversion shall be rounded to the next higher whole number of Units.

4.       EVENTS OF DEFAULT.

         The following shall constitute "Events of Default" under the Bonds:

         (a) The Company fails to make any payment of interest or principal
under the Bonds when due; or

         (b) The Company fails to have a sufficient number of shares of Series D
Preferred Stock authorized no later than seven (7) business days after the
Conversion Notification Date to permit conversion of the Bonds; or

         (c) The Company fails duly to perform or observe any other term,
covenant or agreement contained in the Bonds for a period of 30 days after the
date on which written notice of such failure, requiring the Company to remedy
the same, shall first have been given to the Company by the holders of at least
25% in aggregate principal amount of the Bonds as from time to time outstanding;
or

         (d) A court having jurisdiction in the premises enters a decree or
order for relief in respect of the Company in an involuntary case or proceeding
under any applicable bankruptcy, insolvency, reorganization or other similar law
now or hereafter in effect, or appointing a receiver, liquidator, assignee,
custodian, trustee, sequestrator (or similar official) of the Company or for any
substantial part of the property of it or ordering the winding-up or liquidation
of the affairs of it and such decree or order remains unstayed and in effect for
a period of 30 consecutive days; or

         (e) Either the Company, Genetic Laboratories Wound Care, Inc., a
Minnesota corporation, or Sunshine Products, Inc., a Missouri corporation, or
any other subsidiary of the Company, commences a voluntary case or proceeding
under any applicable bankruptcy,

                                       2

<PAGE>


insolvency, reorganization or other similar law now or hereafter in effect, or
consents to the entry of an order for relief in an involuntary case under any
such law, or consents to the appointment of or taking possession by a receiver,
liquidator, assignee, trustee, custodian, sequestrator (or similar official) of
the Company or for any substantial part of its property, or makes any general
assignment for the benefit of creditors, or admits in writing its inability to
pay its debts as they become due or takes any corporate action in furtherance of
any of the foregoing; or

         (f) An event of default, as defined in any indenture or instrument
evidencing or under which the Company has outstanding at least $200,000 (or its
equivalent in another currency), in aggregate principal amount of indebtedness
for borrowed money, has occurred and is continuing and such default involves the
failure to pay the principal or interest of such indebtedness (or any part
thereof), when due and payable after the expiration of any applicable grace
period with respect thereto, or such indebtedness has been accelerated so that
the same becomes due and payable prior to the date on which the same would
otherwise have become due and payable, and failure to pay is not cured by the
Company within 30 days after such failure or such acceleration is not rescinded
or annulled within 60 days after notice thereof has first been given to the
Company; provided that if such event of default under such indenture or
instrument is remedied or cured by the Company or waived by the holders of such
indebtedness, then the Event of Default hereunder by reason thereof shall be
deemed likewise to have been thereupon remedied, cured or waived without further
action upon the part of any of the Bondholders.

         If an Event of Default occurs and is continuing, the Bondholders
holding not less than 50% of the aggregate principal amount of the Bonds then
outstanding may, by written notice to the Company, declare the principal of the
Bond and the interest accrued hereon to be due and payable immediately in cash.
If an Event of Default, or an event which would with the passing of time or the
giving of notice or both be an Event of Default, occurs and is continuing, the
Company shall within two (2) business days of becoming aware thereof notify the
Bondholder in writing of such Event of Default.

5.       MERGER, CONSOLIDATION, SALE, CONVEYANCE OR ASSUMPTION.

         (a) The Company will not merge or consolidate with, or sell or convey
all or substantially all of its assets to, any other corporation unless (i)
either (A) the Company is the surviving corporation in the case of a merger or
(B) the surviving, resulting or transferee corporation expressly assumes the due
and punctual payment of all the Bonds according to their tenor and the due and
punctual performance of all of the covenants and obligations of the Company
under the Bonds, by supplemental agreement reasonably satisfactory to the
Bondholders, (ii) the surviving, resulting or transferee corporation, if not
organized and validly existing under the laws of any state of the United States
or the District of Columbia, expressly agrees to make payments under the Bonds
free of any deduction or withholding for or on account of taxes, levies, imposts
and charges whatsoever imposed by or for the account of the jurisdiction where
such successor corporation is generally subject to taxation (or any political
subdivision or taxing authority thereof or therein) in a manner equivalent to
that set forth herein subject to the exceptions contained in such forms of the
Bonds, and (iii) the Company or such successor corporation, as the case may be,
is not, immediately after such merger, consolidation, sale or

                                       3

<PAGE>


conveyance, in default in the performance of any covenants or obligations of the
Company under the Bonds.

         (b) Upon any merger, consolidation, sale, conveyance or assumption as
provided in Section 5(a), the successor or assuming corporation shall succeed to
and be substituted for, and may exercise every right and power of and be subject
to all the obligations of, the Company under the Bonds with the same effect as
if such successor or assuming corporation had been named as the Company therein
and herein and the Company shall be released from its liability as obligor under
the Bonds; provided that any successor or assuming corporation shall have the
obligation to purchase the Bonds only as a result of circumstances which occur
subsequent to such merger, consolidation, sale, conveyance or assumption and as
a result of which the Company would have had such obligation if the Company had
remained the obligor on the Bonds.

                  In case of any such merger, consolidation, sale, conveyance or
assumption, such successor or assuming corporation shall succeed to and be
substituted for the Company with the same effect, subject to (in the case of a
merger to which the Company is a party) Section 5(b) of the Bonds, as if it had
been named in the Bonds as the Company; the Company shall thereupon be relieved
of any further obligation or liability hereunder or upon the Bonds, and the
Company, as the predecessor corporation may thereupon or at any time thereafter
be dissolved, wound up or liquidated. Subject to all the terms, conditions and
limitations in the Bonds, the successor or assuming corporation shall deliver
any Bonds which previously have been signed and delivered by the officers of the
Company. All the Bonds so issued shall in all respects have the same legal rank
and benefit as the Bonds theretofore or thereafter issued as though all of such
Bonds had been issued at the date of the execution hereof.

                  In case of any merger, consolidation, sale, conveyance or
assumption, such changes in phraseology and form (but not in substance) may be
made in the Bonds thereafter to be issued as may be appropriate.

6.       REPLACEMENT, TRANSFER AND EXCHANGE OF BONDS.

         (a) In case any Bond shall at any time become mutilated, destroyed,
stolen or lost and such Bond or evidence of the loss, theft or destruction
thereof (together with the indemnity hereinafter referred to and such other
documents or proof as may be required) shall be delivered to the Company, a new
Bond of like tenor and date will be issued by the Company in exchange for the
Bond so mutilated, or in lieu of the Bond so destroyed, stolen or lost, but, in
the case of a destroyed, stolen or lost Bond only upon receipt of evidence
satisfactory to the Company that such Bond was destroyed, stolen or lost, and if
required by the Company, upon receipt also of indemnity satisfactory to the
Company. All expenses and reasonable charges associated with procuring such
indemnity and with the preparation, authentication and delivery of a new Bond
shall be borne by the owner of the Bond so mutilated, destroyed, stolen or lost.

         (b) Bonds are exchangeable at the office of the Company in Princeton,
New Jersey or as designated by the Company for such purpose, for an equal
aggregate principal amount of Bonds of authorized denominations as required by
the Bondholder surrendering the same. In the

                                       4

<PAGE>


event of conversion of a Bond in part only, a new Bond or Bonds for the
unredeemed or unconverted portion hereof will be issued in the name of the
Bondholder.

         (c) The costs and expenses of effecting any exchange or registration of
transfer pursuant to the foregoing provisions, except for the expenses of
delivery by other than regular mail (if any) and except, if the Company shall so
require, the payment of a sum sufficient to cover any tax or other governmental
charge or insurance charges that may be imposed in relation thereto, will be
borne by the Company.

         (d) For purposes of the provisions of the Bond, any Bond authenticated
and delivered pursuant hereto shall, as of any date of determination, be deemed
to be "outstanding," except for:

                  (i) Bonds previously converted, or canceled by the Company or
         delivered to the Company for cancellation;

                  (ii) Bonds which have become due and payable at maturity or
         otherwise and with respect to which monies or shares of Common Stock,
         as applicable, sufficient to pay the principal thereof and interest
         thereon shall have been made available to the Company; or

                  (iii) Bonds in lieu of or in substitution for which other
         Bonds have been authenticated and delivered pursuant hereto;

provided, however, that in determining whether the holders of the requisite
principal amount of outstanding Bonds are present at a meeting of Bondholders
for quorum purposes or have given any request, demand, authorization, direction,
notice, consent or waiver hereunder, Bonds owned by the Company or any
subsidiary thereof shall be disregarded and deemed not to be outstanding.

7.       MODIFICATIONS AND AMENDMENTS.

         (a) Without the consent of any Bondholders, modifications of or
amendments to the Bonds may be made for any of the following purposes:

                  (i) to evidence the succession of another corporation to the
         Company and the assumption by any such successor of the covenants of
         the Company in the Bonds;

                  (ii) to add to the covenants of the Company for the benefit of
         the Bondholders, or to surrender any right or power herein conferred
         upon the Company;

                  (iii) to make provision with respect to the conversion rights
         of Bondholders pursuant to Section 2 hereof;

                  (iv) to cure any ambiguity, to correct or supplement any
         provision herein which may be inconsistent with any other provision
         herein; and

                  (v) to make any other provisions with respect to matters or
         questions arising under the Bond.

                                       5

<PAGE>


         No such action pursuant to this paragraph (a) may adversely affect the
interests of the Bondholders.

         (b) Modifications and amendments to these Bonds may be made, and future
compliance with or past default by the Company under any of the provisions
thereof may be waived, with the written consent of the holders of at least a
majority in aggregate principal amount of the Bonds at the time outstanding;
provided, that no such modification, amendment or waiver may, without the
consent of each Bondholder affected thereby:

                  (i) waive a default in the payment of the principal of or
         interest on any Bond;

                  (ii) change the Stated Maturity (except as contemplated
         herein) of the principal of or any installment of interest on, any
         Bond, or reduce the principal amount thereof or the rate of interest
         thereon, or change the coin or currency in which any Bond or the
         interest thereon is payable, or adversely affect the right to convert
         any Bonds as provided in Section 2 or modify the provisions of the
         Bonds with respect to subordination of the Bonds in a manner adverse to
         the Bondholders;

                  (iii) reduce the requirements of Section 6 hereof for quorum
         or voting, or reduce the percentage in principal amount of the
         outstanding Bonds the consent of whose holders is required for any
         amendment or modification of the Terms and Conditions of the Bonds;

                  (iv) change the obligation of the Company to maintain an
         office or agency in Princeton, New Jersey; or

                  (v) modify any of the provisions of this Section except to
         increase any such percentage or to provide that certain other
         provisions of the Bonds cannot be modified or waived without the
         consent of the holder of each outstanding Bond affected thereby.

8.       NON-BUSINESS DAYS.

         In any case where the date of maturity of the principal of or interest
on the Bonds or the date fixed for redemption of any Bond shall be at any place
of payment a Saturday, Sunday, a legal holiday or a day on which banking
institutions in Princeton, New Jersey are authorized or obligated by law or
executive order to close, then payment of principal or interest need not be made
on such date at such place but may be made on the next succeeding day at such
place of payment which is not a Saturday, Sunday, a legal holiday or a day on
which banking institutions in Princeton, New Jersey are authorized or obligated
by law or executive order to close, with the same force and effect as if made on

Parties a security interest in the Collateral (as hereinafter defined);

         NOW THEREFORE, in consideration of the mutual promises contained herein
and other good and valuable consideration, and intending to be legally bound
hereby, the parties agree as follows:

         1. COLLATERAL. For purposes of this Agreement, "Collateral" means all
property now owned or hereafter acquired by Debtors and any and all inventory,

         2. SECURITY INTEREST. As security for the prompt payment of the
Obligations, when due, at maturity or by acceleration upon default, the Debtors
hereby grant to the Secured Parties a lien upon and a continuing security
interest in all Collateral in which the Debtors now or may hereafter acquire an
interest. Provided, however, the security interest granted hereby is, and shall
be, subject to the prior security interest in the Collateral ("Prior Security
Interest") granted to the holders of the Company's $875,000 aggregate principal
amount convertible bonds due August 15, 2000.

         3. REPRESENTATIONS AND WARRANTIES. The Debtors represent and warrant to
the Secured Parties as follows:

               a.  Binding Agreement.  This Agreement constitutes the valid and
legally binding obligation of the Debtors enforceable in accordance with its
terms.

               b. Warranty of Title. Each item of Collateral is and will remain
at all times prior to payment in full of the Obligations, the sole property of
the respective Debtors free and clear of any lien, encumbrance, security
interest or claim of adverse interest other than (i) interests granted to the
Secured Parties herein, (ii) the Prior Security Interest, (iii) interests of
record as of the date hereof, and (iv) purchase money security interests in
after acquired Collateral.

                                       2

<PAGE>


         4. COVENANTS. The Debtors covenant and agree that so long as any of the
Obligations remain outstanding:

               a. Further assurances. The Debtors will execute such financing
statements, continuation statements, security agreements and other documents, in
form satisfactory to the Secured Parties, as may be necessary to perfect, or
continue perfection of, the security interests of the Secured Parties in the
Collateral. The Debtors agree that the Secured Parties may file a carbon,
photographic copy or other reproduction of any financing statement in lieu of an
executed original thereof.

               b. Maintenance of Records. The Debtors will keep and maintain, at
their own cost and expense, satisfactory, complete and current records of the
Collateral. The Debtors will protect their records against fire, theft, loss or
any other manner of destruction.

               c. Maintenance of Collateral. The Debtors will keep the
Collateral in good condition and free from all liens and other security
interests and the Debtors will not use the Collateral illegally, sell or offer
to sell (except in the ordinary course of business) or otherwise transfer or
encumber the Collateral or permit it to be affixed to real or personal property
without the prior written consent of the Secured Parties.

               d. Taxes. The Debtors will pay promptly when due all taxes,
charges and assessments, including penalties and interest, that are or may
become a lien on the Collateral or any part thereof except to the extent that
they may be contested in good faith and by appropriate proceedings.

               e. Inspection and Delivery of Collateral, Books and Records. The
Secured Parties, or their agents, may at anytime and from time to time inspect
the Collateral and the books and records of the Debtors pertaining thereto.

<PAGE>


               f. Expenses. The Debtors shall be liable for, and agree to pay
the Secured Parties, any and all expenses incurred or paid by the Secured
Parties in enforcing their rights under this Agreement, including reasonable
counsel fees and legal expenses. At their option, the Secured Parties may
discharge taxes, liens, security interests or other encumbrances on the
Collateral and may pay for the repair of damage to the Collateral, the
maintenance and preservation thereof and insurance thereon. The Debtors agree to
reimburse the Secured Parties on demand for any payments so made, and, until
such reimbursement, the amount of any such payments, with interest at the
maximum contract rate permitted by law from date of payment until the date of
reimbursement, shall be added to the Obligation and shall be secured by this
Security Agreement.

               g. Insurance. The Debtors will continuously insure the Collateral
with a responsible company or companies against fire (with extended coverage) in
the full insurable value of the Collateral and against other casualties in
reasonable amounts. If the Debtors fail to pay the premium, the Secured Parties
at their option may do so for the Debtors' account and add the amount thereof to
the Obligation.

         5.    EVENTS OF DEFAULT.

               a. Events of Default. The occurrence of any one or more of the
following events shall constitute an Event of Default hereunder:

                  (1) Derma Sciences fails to make any payment of interest or
principal under the Bonds when due; or

                  (2) Derma Sciences fails to have a sufficient number of shares
of Series D Preferred Stock authorized no later than seven (7) days after the
Conversion Notification Date (as defined in the Bonds) to permit conversion of
the Bonds; or

                                       4

<PAGE>


                  (3) Derma Sciences fails duly to perform or observe any other
term, covenant or agreement contained in the Bonds for a period of 30 days after
the date on which written notice of such failure, requiring the Company to
remedy the same, shall first have been given to the Company by the holders of at
least 25% in aggregate principal amount of the Bonds as from time to time
outstanding; or

                  (4) A court having jurisdiction in the premises enters a
decree or order for relief in respect of any of the Debtors in an involuntary
case or proceeding under any applicable bankruptcy, insolvency, reorganization
or other similar law now or hereafter in effect, or appointing a receiver,
liquidator, assignee, custodian, trustee, sequestrator (or similar official) of
any of the Debtors or for any substantial part of the property thereof or
ordering the winding-up or liquidation of the affairs of any of the Debtors it
and such decree or order remains unstayed and in effect for a period of 30
consecutive days; or

                  (5) Any of the Debtors commences a voluntary case or
proceeding under any applicable bankruptcy, insolvency, reorganization or other
similar law now or hereafter in effect, or consents to the entry of an order for
relief in an involuntary case under any such law, or consents to the appointment
of or taking possession by a receiver, liquidator, assignee, trustee, custodian,
sequestrator (or similar official) of any of the Debtors or for any substantial
part of the property thereof, or makes any general assignment for the benefit of
creditors, or admits in writing its inability to pay its debts as they become
due or takes any corporate action in furtherance of any of the foregoing; or

                  (6) An event of default, as defined in any indenture or
instrument evidencing or under which any of the Debtors has outstanding at least
$200,000 (or its equivalent in another currency), in aggregate principal amount
of indebtedness for borrowed money, has occurred and

                                       5

<PAGE>


         is continuing and such default involves the failure to pay the
principal or interest of such indebtedness (or any part thereof), when due and
payable after the expiration of any applicable grace period with respect
thereto, or such indebtedness has been accelerated so that the same becomes due
and payable prior to the date on which the same would otherwise have become due
and payable, and failure to pay is not cured within 30 days after such failure
or such acceleration is not rescinded or annulled within 60 days after notice
thereof has first been given to Derma Sciences; provided that if such event of
default under such indenture or instrument is remedied or cured by Derma
Sciences or waived by the holders of such indebtedness, then the Event of
Default hereunder by reason thereof shall be deemed likewise to have been
thereupon remedied, cured or waived without further action upon the part of any
of the Bondholders.

               b. Remedies on Default . Upon any such Event of Default and at
any time thereafter, the Secured Parties holding 50% or more of the aggregate
principal amount of the Bonds then outstanding may declare all obligations
secured hereby to be immediately due and payable without notice, protest,
presentment or demand, all of which are hereby expressly waived by the Debtors,
and may proceed to enforce payment of the same and exercise any and all of the
rights and remedies set forth herein or provided by the law. The Secured Parties
will give the Debtors reasonable notice of the time and place of any public sale
of the Collateral or any part hereof or of the time after which any private sale
or any other intended disposition thereof is to be made. The requirements of
reasonable notice shall be deemed met if such notice is mailed, postage prepaid,
to the address of the Debtors shown at the head of this Agreement at least ten
(10) days before the time of the sale or disposition, but nothing contained
herein shall be construed to mean that any other notice or a shorter period of
time does not constitute reasonable notice for the sale of the Collateral or any
part thereof. Expenses of retaking, holding, preparing

                                       6

<PAGE>


for sale, selling or the like shall include the Secured Parties' reasonable
counsel fees and legal expenses. Should an Event of Default occur, the Debtors
shall upon request by the Secured Parties assemble the Collateral or any
designated part thereof and make it available to the Secured Parties at such
place as is designated by the Secured Parties. The Debtors shall pay the Secured
Parties, on demand, any and all expenses, including all reasonable counsel fees

                                       4

<PAGE>


         of a majority of the Registrable Securities covered by such
         Registration Statement shall reasonably object (provided that the
         Company may assume, for the purposes of the foregoing that any Holder
         has no objection if the Company has not received notice from such

         such Holder);

                (b) prepare and file with the SEC such amendments and

         Statement effective for the applicable period and cause the Prospectus
         as so supplemented to be filed pursuant to Rule 424 under the
         Securities Act; and comply with the provisions of the Securities Act
         with respect to the disposition of all securities covered by such
         Registration Statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth in
         such Registration Statement or supplement to the Prospectus;

                (c) notify each Purchaser and the Holders promptly, and confirm
        such advice in writing,

                      (1) when the Prospectus or any Prospectus supplement or
                  post-effective amendment has been filed, and, with respect to
                  the Registration Statement or any post-effective amendment,
                  when the same has become effective,

                      (2) of the issuance by the SEC of any stop order
                  suspending the effectiveness of the Registration Statement or
                  the initiation of any proceedings for that purpose, and

                      (3) of the receipt by the Company of any notification with
                  respect to the suspension of the qualification of the

                  initiation or threatening of any proceeding for such purpose;

                (d) make every reasonable effort to obtain the withdrawal of any
         order suspending the effectiveness of the Registration Statement at the
         earliest possible moment;

         request, each Holder, at least one conformed copy of the Registration
         Statement and any post-effective amendment thereto, including financial
         statements and schedules, all documents incorporated therein by
         reference and all exhibits (including those incorporated by reference);

                (f) deliver to each Purchaser and each Holder without charge, as

         amendment or supplement thereto by each Purchaser

                                       5

<PAGE>


        and each Holder in connection with the offering and sale of the
        Registrable Securities covered by the Prospectus or any amendment or
        supplement thereto;

                (g) use its reasonable efforts to cause the Registrable
         Securities covered by the Registration Statement to be registered with

         of such Registrable Securities in such jurisdictions as the Holders may
         reasonably specify in response to inquiries to be made by the Company,
         provided that the Company will not be required to qualify generally to
         do business in any jurisdiction where it is not then so qualified or to
         take any action which would subject it to general service of process in
         any such jurisdiction where it is not then so subject;

                (h) if any event shall occur as a result of which it is
         necessary, in the opinion of counsel for the Company, to amend or
         supplement the Prospectus in order to make the Prospectus not
         misleading in the light of the circumstances existing at the time it is
         delivered by a Holder, prepare a supplement or post-effective amendment
         to the Registration Statement or the related Prospectus or any document
         incorporated therein by reference or file any other required document
         so that, as thereafter delivered to the Holders, the Prospectus will
         not contain an untrue statement of a material fact or omit to state any
         material fact necessary to make the statements therein not misleading;

                (i) obtain a CUSIP number for all Registrable Securities (unless
         already obtained), not later than the Effective Date;

                (j) make available for inspection during normal business hours
         by a representative of the Holders of a majority of the Registrable
         Securities and any attorney or accountant retained by such

         documents and properties of the Company, and cause the Company's
         officers, directors and employees to supply all information reasonably
         requested by such Holders or any such attorney or accountant in
         connection with the Registration Statement; provided that all such
         records, information or documents shall be kept confidential by such
         Persons unless disclosure of such records, information or documents is
         required by court or administrative order or is generally available to
         the public other than as a result of disclosure in violation of this
         Section 4(j);

                (k) otherwise use its best efforts to comply with all applicable
         rules and regulations of the SEC, and make generally available to its
         security holders an earnings statement satisfying the provisions of
         Section 11(a) of the Securities Act (in accordance with Rule 158
         thereunder or otherwise), no later than 45 days after the end of the
         12-month period (or 90 days, if such period is a fiscal year) beginning
         with the first month of the Company's first fiscal quarter commencing
         after the Effective Date, which statements shall cover said 12-month
         period;

                (l) if at any time an event of the kind described in Section
         4(h) shall occur, notify each Purchaser and the Holders that the use of
         the Prospectus must be

                                       6

<PAGE>


        discontinued (the Company will not declare any such "black-out" periods
        in excess of twenty business days during any twelve month period, unless
        otherwise required); and

                (m) on or prior to the date the Registration Statement is
         declared effective by the SEC, cause all of the Underlying Common Stock
         to be listed for trading on the Boston Stock Exchange (or on any other
         national securities exchange) and the Nasdaq SmallCap Market.

                Each Holder as to which any registration is being effected
         agrees, as a condition to the registration obligations with respect to
         such Holder provided herein, to furnish to the Company such information
         regarding the distribution of such Registrable Securities as the
         Company may from time to time reasonably request in writing.

                Each Holder agrees by acquisition of such Registrable Securities
         that, upon receipt of any notice from the Company described in Section
         4(l), such Holder will forthwith discontinue disposition of Registrable
         Securities until such Holder's receipt of the copies of the
         supplemented or amended Prospectus contemplated by Section 4(f) hereof,
         or until it is advised in writing by the Company (which notice the
         Company shall give as promptly as possible), that the use of the
         Prospectus may be resumed, and has received copies of any additional or
         supplemental filings which are incorporated by reference in the
         Prospectus, and, if so directed by the Company, such Holder will
         deliver to the Company (at the Company's expense) all copies, other
         than permanent file copies then in such Holder's possession, of the
         Prospectus covering such Registrable Securities current at the time of
         receipt of such notice.

         5. REGISTRATION EXPENSES. All of the following expenses ("Registration

Agreement will be borne by the Company, regardless of whether the Registration

statement, omission or alleged omission was completely corrected in an amendment
or supplement to the Prospectus and if, having previously been furnished by or
on behalf of the Company with copies of the Prospectus as so amended or
supplemented, such Holder thereafter fails to deliver such Prospectus as so
amended or supplemented, prior to or concurrently with the sale of a Registrable
Security to the person asserting such loss, claim, damage, liability or expense
who purchased such Registrable Security which is the subject thereof from such
Holder. This indemnity will be in addition to any liability which the Company
may otherwise have.

         If any action or proceeding (including any governmental investigation
or inquiry) shall be brought or asserted against any Indemnified Holder in
respect of which indemnity may be sought from the Company, such Indemnified
Holder shall promptly notify the Company in writing (but the omission to so
notify the Company shall not relieve it of any liability that it may have
against any Indemnified Holder otherwise than under this subsection), and the
Company shall assume the defense thereof, including the employment of counsel
reasonably satisfactory to such Indemnified Holder and the payment of all
expenses. Indemnified Holders shall have the right, collectively, to employ
their own counsel in any such action and to participate in the defense thereof,
but the fees and expenses of such counsel shall be the expense of the
Indemnified Holders unless (a) the Company has agreed to pay such fees and
expenses or (b) the Company shall have failed to assume the defense of such
action or proceeding and have failed to employ counsel reasonably satisfactory
to the Indemnified Holders in any such action or proceeding or (c) the named
parties to any such action or

                                       8

<PAGE>


proceeding (including any impleaded parties) include the Indemnified Holders and
the Company, and the Indemnified Holders shall have been advised by counsel that
there may be one or more legal defenses available to the Indemnified Holders
which are different from or additional to those available to the Company (in
which case, if the Indemnified Holders notify the Company in writing that they
elect to employ their own counsel at the expense of the Company, the Company
shall not have the right to assume the defense of such action or proceeding on
behalf of the Indemnified Holders, it being understood, however, that the
Company shall not, in connection with any one such action or proceeding or
separate but substantially similar or related actions or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys (together with appropriate local counsel) at any time for the
Indemnified Holders which firm shall be designated in writing by the Indemnified
Holders representing at least a majority of the aggregate principal amount of
the outstanding Registrable Securities). Any such fees and expenses payable by
the Company shall be paid to the Indemnified Holders entitled thereto as
incurred by the Indemnified Holders. The Company shall not be liable for any
settlement of any such action or proceeding effected without its written
consent, but if settled with its written consent, or if there be a final
judgment for the plaintiff in any such action or proceeding, the Company agrees
to indemnify and hold harmless the Indemnified Holders from and against any loss
or liability by reason of such settlement or judgment.

                (b) Indemnification by Holder. Each Holder agrees to indemnify
and hold harmless the Company, its respective directors and officers and each
Person, if any, who controls the Company within the meaning of either Section 15
of the Securities Act or Section 20 of the Exchange Act to the same extent as
the foregoing indemnity from the Company to such Holder, but only with respect
to information relating to such Holder furnished in writing by such Holder
expressly for use in any Registration Statement or Prospectus, or any amendment
or supplement thereto, or any preliminary prospectus. In case any action or
proceeding shall be brought against the Company or its respective directors or
officers or any such controlling person, in respect of which indemnity may be
sought against a Holder, such Holder shall have the rights and duties given the
Company, and the Company or its respective directors or officers or such
controlling person shall have the rights and duties given to each holder by the
preceding paragraph. In no event shall the liability of any Holder hereunder be
greater in amount than the dollar amount of the proceeds received by such Holder
upon the sale of the Registrable Securities giving rise to such indemnification
obligation.

                (c) Contribution. If the indemnification provided for in this
Section 6 is unavailable to an indemnified party under Section 6(a) or Section
6(b) hereof (other than by reason of exceptions provided in those Sections) in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then each applicable indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
expenses, (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company from the sale of the Preferred Shares to each
Purchaser pursuant to the Purchase Agreement on the one hand and each Holder
from the offering of the Registrable Securities by such Holder, on the other
hand, or (ii) if the allocation provided by clause (i) above is not permitted by
applicable

                                       9

<PAGE>


law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
Company on the one hand and each Holder on the other in connection with the
statements or omissions that resulted in such losses, claims, damages, or
liabilities, as well as the other relevant equitable considerations. The
relative benefits received by the Company on the one hand and each Holder on the
other shall be deemed to be in the same proportion as the aggregate amount paid
by each Purchaser to the Company pursuant to the Purchase Agreement for the
Registrable Securities purchased by such Holder that were sold pursuant to the
Registration Statement bears to the difference (the "Difference") between the
amount such Holder paid for the Registrable Securities that were sold pursuant
to the Registration Statement and the amount received by such Holder from such
sale. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the particular Holder and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such untrue statement or omission. The Company and the Holders agree that it
would not be just and equitable if contributions pursuant to this Section 6(c)
were to be determined by pro rata allocation or by any other method of
allocation that does not take account of the equitable consideration referred to
in the first sentence of this Section 6(c). The amount paid by an indemnified
party as a result of the losses, claims, damages or liabilities referred to in
the first sentence of this Section 6(c) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigation or defending against any action or claim that is the subject of
this Section 6(c). Notwithstanding the provisions of this Section 6(c), each
Holder shall not be required to contribute any amount in excess of the amount by
which the Difference exceeds the amount of any damages that such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act),
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

         7. RULE 144 AND RULE 144A. For so long as the Company is subject to the
reporting requirements of Section 13 or 15 of the Exchange Act, the Company
covenants that it will file the reports required to be filed by it under the
Securities Act and Section 13(a) or 15(d) of the Exchange Act and the rules and
regulations adopted by the SEC thereunder. If the Company is not subject to the
reporting requirements of Section 13 or 15 of the Exchange Act, the Company also
covenants that it will provide the information required pursuant to Rule
144A(d)(4) under the Securities Act upon the request of any Holder which
continue to be "restricted securities" within the meaning of Rule 144(a)(3)
under the Securities Act and it will take such further action as any holder of
such Registrable Securities may reasonably request, all to the extent required
from time to time to enable such holder to sell its Registrable Securities
without registration under the Securities Act within the limitation of the
exemptions provided by (a) Rule 144 under the Securities Act, as such Rule may
be amended from time to time, so long as such provision does not require the
public filing of information relating to the Company which the Company is not
otherwise required to file, (b) Rule 144A under the Securities Act, as such Rule
may be amended from time to time, or (c) any similar rule or regulation
hereafter adopted by the SEC that does not require the public filing of
information relating to the Company.

                                       10

<PAGE>


Upon the request of any Holder, the Company will deliver to such Holder a
written statement as to whether it has complied with such requirements.

         8.     MISCELLANEOUS.

                (a) No Inconsistent Agreements. The Company will not on or after
the date of this Agreement enter into any agreement with respect to their
securities which is inconsistent with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. The rights granted
to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Company's securities
under any such agreements.

                (b) Adjustments Affecting Registrable Securities. The Company
will not take any action, or permit any change to occur, with respect to the
Registrable Securities which would adversely affect the ability of the Holders
to include such Registrable Securities in a registration undertaken pursuant to
this Agreement.

                (c) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of a majority of the Registrable Securities.

                (d) Notices. All notices, requests, consents and other
communications hereunder shall be by telecopier, with a copy being mailed by a
nationally recognized overnight express courier, and shall be deemed given when
receipt is acknowledged by transmit confirmation report, and shall be delivered
as addressed as follows:

                  (1) if to a Purchaser, at the most current address given by
         the Purchaser to the Company in accordance with the provisions of this
         Section 8(d) which address initially is as set forth at the head of
         this Agreement;

                  (2) if to a Holder, at its address of record as indicated on
         the books of the transfer agent and registrar for the Registrable
         Securities; and

                  (3) if to the Company, initially at its address set forth at
         the head of this Agreement and thereafter at such other addresses
         notice of which is given in accordance with the provisions of this
         Section 8(d).

         (e) Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors and assigns of each of the parties,
including without limitation and without the need for an express assignment,
subsequent Holders.

         (f) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

                                       11

         (g) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         (h) Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York (without reference to its
rules as to conflicts of law) and the federal law of the United States of
America.

         (i) Severability. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

         (j) Entire Agreement. This Agreement is intended by the parties as a
final expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein
with respect to the registration rights granted by the Company with respect to
the securities sold pursuant to the Purchase Agreement. This Agreement
supersedes all prior agreements and understandings between the parties with
respect to such subject matter.

         (k) Calculation of Majority. For purposes of determining whether the
Holders of a majority of the Registrable Securities have taken action pursuant
thereto, any Preferred Shares and Warrants then outstanding shall be deemed to
have been converted into Underlying Common Stock which shares shall be treated
as outstanding for purposes hereof.

         9. COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when
taken together, shall constitute but one instrument, and shall become effective
when one or more counterparts have been signed by each party hereto and
delivered to the other parties. Facsimile signatures are considered to be
originals and shall have the same effect.

                                       OF

                          THE SERIES OF PREFERRED STOCK

                                       OF

                              DERMA SCIENCES, INC.

                                TO BE DESIGNATED

                      SERIES D CONVERTIBLE PREFERRED STOCK

         Pursuant to the Pennsylvania Business Corporation Law of 1988, I,
Edward J. Quilty, Chief Executive Officer and Chairman of the Board of Derma
Sciences, Inc., a Pennsylvania corporation (the "Corporation"), hereby certify
that the following is a true and correct copy of a resolution duly adopted by
the Corporation's Board of Directors at a meeting held on __________, ____ at
which a quorum was present and acting throughout, and that said resolution has
not been amended or rescinded and is in full force and effect at the date
hereof:

         RESOLVED, that pursuant to the authority expressly granted and vested
in the Board of Directors of the Corporation by the Corporation's Articles of
Incorporation, as amended to date, the Board of Directors hereby creates a
series of preferred stock of the Corporation, par value $.01 per share, to be
designated "Series D Convertible Preferred Stock" (the "Series D Preferred
Stock") and to consist of __________________________________________________
shares, and hereby fixes the voting powers, designations, preferences and
relative, participating, optional or other rights and the qualifications,
limitations or restrictions thereon, of the Series D Preferred Stock, as
follows:

1.       VOTING RIGHTS. The holders of Series D Preferred Stock shall have the
         right to vote, together with the holders of all the outstanding shares
         of Series A Convertible Preferred Stock, Series B Convertible Preferred
         Stock , Series C Convertible Preferred Stock and Common Stock, and not
         by classes, except as otherwise required by Pennsylvania law, on all
         matters on which holders of Common Stock are entitled to vote. Each
         holder of shares of Series D Preferred Stock shall have the right to
         cast one vote for each share.

2.       LIQUIDATION OR DISSOLUTION. Subject to the prior rights of the
         Corporation's creditors and holders of securities equal or senior to
         the Series D Preferred Stock in respect of distributions upon
         liquidation, dissolution or winding-up of the Corporation, in the event
         of the voluntary or involuntary liquidation, dissolution or winding-up
         of the Corporation, the holders of Series D Preferred Stock shall be
         entitled to receive the purchase price per share (the "Liquidation
         Preference"), together with accrued and unpaid dividends payable
         thereon to the date fixed for

                                       1

<PAGE>


         payment of such distribution, if any, which shall be payable on a pro
         rata basis among holders of Preferred and Common Stock, all of which
         shall be paid in cash. If, upon any such liquidation, dissolution or
         winding-up of the Corporation, the assets distributable among the
         holders of Series D Preferred Stock (and any series of preferred stock
         ranking in parity with the Series D Preferred Stock in respect of
         distributions upon liquidation, dissolution or winding-up of the
         Corporation) shall be insufficient to permit the payment in full to
         such holders of the preferential amount payable to such holders
         determined as aforesaid, then the holders of Series D Preferred Stock
         will share ratably in any distribution of the Corporation's assets in
         proportion to the respective preferential amounts that would have been
         payable if such assets were sufficient to permit payment in full of all
         such amounts. For purposes of the foregoing, the Corporation's Series A
         Convertible Preferred Stock, Series B Convertible Preferred Stock and
         Series C Convertible Preferred Stock shall rank in parity with the
         Series D Preferred Stock. After payment of the full amount of the
         liquidating distribution to which they are entitled, the holders of
         Series D Preferred Stock will not be entitled to any further
         participation in any distribution of assets by the Corporation. Under
         this Section 2, a distribution of assets in any dissolution,
         winding-up, liquidation or reorganization shall include (a) any
         consolidation or merger of the Corporation with or into any other
         corporation in which the Corporation is not the surviving corporation,
         (b) a sale or other disposition of all or substantially all of the
         Corporation's assets in consideration for cash and/or the issuance of
         equity securities of another corporation, or (c) a Change of Control of
         the Company. Under this Section 2, a distribution of assets in any
         dissolution, winding-up, liquidation or reorganization shall not
         include any dissolution, liquidation, winding-up or reorganization of
         the Corporation immediately followed by reincorporation of a successor
         corporation, provided that the dissolution, liquidation, winding-up or
         reorganization does not amend, alter, or change the preferences or
         rights of the Series D Preferred Stock or the qualifications,
         limitations or restrictions thereof in a manner that adversely affects
         the Series D Preferred Stock.

3.       CONVERSION RIGHTS.

         (a)      CONVERSION OF SERIES D PREFERRED STOCK. Each share of Series D
                  Preferred Stock shall be convertible at the option of the
                  holder thereof into one fully paid and non-assessable share of
                  Common Stock, ("Conversion Share(s)") subject to the
                  provisions set forth herein.

         (b)      MECHANICS OF CONVERSION. The holder of any shares of Series D
                  Preferred Stock may exercise the conversion right as to any
                  part thereof by delivering to the Corporation during regular
                  business hours, at the principal office of the Corporation at
                  214 Carnegie Center, Suite 100, Princeton, New Jersey 08540,
                  or at such other principal office as the Corporation may from
                  time to time maintain, a conversion notice in the form
                  attached to the purchase agreement pursuant to which the
                  Series D Preferred Stock is issued (the "Conversion Notice").
                  The Conversion Notice shall include a statement that the
                  holder elects to convert its shares subject to applicable
                  securities laws, the name(s) in which the certificate(s)
                  representing the Conversion Shares to which such holder is
                  entitled are to be issued, and the telecopier number to which
                  the Corporation shall telecopy its confirmation described
                  below. Notice given by telecopier to telecopier number (609)
                  452-0880, Attention: Edward J. Quilty, shall be deemed notice
                  for purposes of

                                       2

<PAGE>


                  this paragraph and shall be deemed given when receipt is
                  acknowledged by transmit confirmation report. Immediately upon
                  receipt of any Conversion Notice, the Corporation shall, by
                  telecopier, confirm receipt thereof at the telecopier number
                  included thereon, which confirmation shall set forth the
                  number of Conversion Shares to be issued by the Corporation as
                  a result of such conversion. The Conversion Notice shall be
                  deemed accepted by the Corporation provided the holder
                  surrenders, or causes any agent for the holder to surrender,
                  the certificate(s) for the Series D Preferred Stock to be
                  converted, duly endorsed or assigned in blank or to the
                  Corporation, at any location set forth above, within seven (7)
                  business days after delivery of the Conversion Notice.
                  Provided that the certificate(s) are delivered in accordance
                  with the preceding sentence, the conversion shall be deemed to
                  have been effected on the date of delivery of the Conversion
                  Notice by telecopier, and such date is referred to herein as
                  the "Conversion Date." Within three (3) business days of
                  receipt by the Corporation of the certificate(s) representing
                  the Series D Preferred Stock, the Corporation shall issue to
                  such holder a certificate or certificates representing the
                  number of full Conversion Shares which such holder is entitled
                  to receive. Unless (i) such Conversion Shares have been held
                  long enough to satisfy the holding period set forth in Rule
                  144(k) (or any successor provision) promulgated under the
                  Securities Act and the converting holder may rely upon Rule
                  144(k) (or any successor provision) at the time of such
                  conversion, (ii) such shares become freely tradeable pursuant
                  to another exemption under the Securities Act, or (iii) the
                  converting holder purchased such shares pursuant to a current
                  prospectus under an effective registration statement covering
                  the purchase and sale of such shares, the certificate(s)
                  representing the Conversion Shares will bear the following

                           REGISTERED  UNDER  THE  SECURITIES  ACT OF  1933,  AS

                           COMPLIES WITH THE  PROSPECTUS  DELIVERY  REQUIREMENTS
                           UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE
                           SALE IS IN COMPLIANCE  WITH THE PLAN OF  DISTRIBUTION
                           AS SET FORTH IN THE PROSPECTUS.

                  The person in whose name the certificate(s) for the Conversion
                  Shares are to be issued shall be deemed to have become a
                  stockholder of record on the applicable Conversion Date unless
                  the transfer books of the Corporation are closed on that date,
                  in which event he or she shall be deemed to have become a
                  stockholder of record on the next succeeding date on which the
                  transfer books are open, but the Conversion Ratio shall be
                  that in effect on the Conversion Date. Upon conversion of only
                  a portion of the number of whole shares covered by a
                  certificate representing shares of Series D Preferred Stock
                  surrendered for conversion, the Corporation shall issue and
                  deliver to or upon the written order of the holder of the
                  certificate so surrendered for conversion, at the expense of
                  the Corporation, a new certificate covering the number of
                  shares of Series D Preferred Stock representing the
                  unconverted portion of the certificate so surrendered which
                  new certificate shall entitle in all respects the holder
                  thereof to the rights of Series D Preferred Stock represented
                  thereby to the same extent as if the certificate theretofore
                  covering such unconverted shares had not been surrendered for
                  conversion.

         (c)      FRACTIONAL SHARES. No fractional shares of Common Stock or
                  scrip shall be issued upon conversion of shares of Series D
                  Preferred Stock. If more than one share of Series D Preferred
                  Stock shall be surrendered for conversion at any one time by
                  the same holder, the number of full shares of Common Stock
                  issuable upon conversion thereof shall be computed on the
                  basis of the aggregate number of shares of Series D Preferred
                  Stock so surrendered. Instead of any fractional shares of
                  Common Stock which would otherwise be issuable upon conversion
                  of any shares of Series D Preferred Stock, the Corporation
                  shall pay a cash adjustment in respect of such fractional
                  interest in an amount determined on the basis of the then
                  Current Market Price per share of Common Stock. Fractional
                  interests shall not be entitled to dividends, and the holders
                  thereof shall not be entitled to any rights as stockholders of
                  the Corporation in respect of such fractional interests.

         (d)      ADJUSTMENTS TO CONVERSION RATIO FOR CERTAIN EVENTS. The number
                  of Conversion Shares underlying each Preferred Share (the
                  "Conversion Ratio") shall be subject to adjustment from time
                  to time as set forth in this subsection (d).

                  (i)      In case at any time, or from time to time, the
                           Corporation shall: (A) take a record of the holders
                           of its Common Stock for the purpose of entitling them
                           to receive a dividend or other distribution payable
                           in shares of capital stock; (B) subdivide its
                           outstanding shares of Common Stock into a larger
                           number of shares; (C) combine its outstanding shares
                           of Common Stock into a smaller number of shares; or
                           (D) issue by reclassification or recapitalization of
                           its Common Stock any other class or series of shares
                           of the Corporation (including any such
                           reclassification or recapitalization in connection
                           with a consolidation

                           or merger in which the Corporation is the continuing
                           corporation), the Conversion Ratio in effect at the
                           time of the record date for such dividend or of the
                           effective date of such subdivision, combination,
                           reclassification or recapitalization shall be
                           proportionately adjusted so that the holder of any
                           Series D Preferred Stock surrendered for conversion
                           after such time shall be entitled to receive the
                           aggregate number and kind of shares which, if such
                           Series D Preferred Stock had been converted
                           immediately prior to such time, such holder would
                           have owned or have been entitled to receive. Such
                           adjustment shall be made successively whenever any
                           event listed above shall occur. In the event that
                           such dividend or distribution is not so made, the
                           Conversion Ratio shall again be adjusted to be the
                           Conversion Ratio which would then be in effect if
                           such record date has not been fixed.

                  (ii)     In case at any time, or from time to time, the
                           Corporation shall (except as hereinafter provided)
                           issue or sell any Additional Shares of Common Stock
                           for a consideration per share of Common Stock less
                           than the Current Market Price, then the Conversion
                           Ratio shall, on the date specified below for
                           determining the Current Market Price, be adjusted to
                           that number determined by multiplying the Conversion
                           Ratio in effect immediately prior to such adjustment
                           by a fraction the numerator of which shall be the
                           number of shares of Common Stock outstanding
                           immediately prior to the issuance of the Additional
                           Shares of Common Stock (including shares deemed to
                           have been issued pursuant to subsection (d)(iii)
                           below) plus the number of shares of Common Stock
                           which the aggregate consideration for the total
                           number of such Additional Shares of Common Stock so
                           issued would purchase at the Current Market Price,
                           and the denominator of which shall be the number of
                           shares of Common Stock outstanding immediately prior
                           to the issuance of such Additional Shares of Common
                           Stock plus the number of such Additional Shares of
                           Common Stock so issued (including shares deemed to
                           have been issued pursuant to subsection (d)(iii)
                           below). For the purposes of this subsection (d)(ii),
                           the date as of which the Current Market Price per
                           share of Common Stock shall be computed shall be the
                           date on which the Corporation shall enter into a
                           legally binding contract for the issuance or sale of
                           such Additional Shares of Common Stock. The
                           provisions of this subsection (d)(ii) shall not apply
                           to any issuance of Additional Shares of Common Stock
                           for which an adjustment is provided under subsection
                           (d)(i) hereof. No adjustment shall be made under this
                           subsection (d)(ii) upon the issuance of any
                           Additional Shares of Common Stock which are issued
                           pursuant to the exercise of any warrants or other
                           subscription or purchase rights or pursuant to the
                           exercise of any conversion or exchange rights in any
                           Convertible Securities, if any such adjustment shall
                           previously have been made upon the issuance of such
                           warrants or other rights or upon the issuance of such
                           Convertible Securities (or upon the issuance of any
                           warrant or other rights therefor) pursuant to
                           subsection (d)(iii) hereof. Adjustments shall be made
                           successively whenever such an issuance of Additional
                           Shares of Common Stock shall occur. In the event that
                           such Additional Shares of Common Stock are not so
                           issued or sold, the Conversion Ratio shall again be
                           adjusted to be the

                           Conversion Ratio which would then be in effect if
                           such issuance had not occurred.

                  (iii)    In case at any time, or from time to time, the
                           Corporation shall take a record of the holders of the
                           Common Stock for the purpose of entitling them to
                           receive a distribution of, or shall otherwise issue,
                           any warrants or other rights to subscribe for or
                           purchase any Additional Shares of Common Stock or any
                           Convertible Securities and the consideration per
                           share for which Additional Shares of Common Stock may
                           at any time thereafter be issuable pursuant to such
                           warrants or other rights or pursuant to the terms of
                           such Convertible Securities shall be less than the
                           Current Market Price, then the Conversion Ratio
                           immediately thereafter shall be adjusted as provided
                           in subsection (d)(ii) hereof on the basis that (A)
                           the maximum number of Additional Shares of Common
                           Stock issuable pursuant to all such warrants or other
                           rights or necessary to effect the conversion or
                           exchange of all such Convertible Securities shall be
                           deemed to have been issued as of the date for the
                           determination of the Current Market Price per share
                           of Common Stock as hereinafter provided, and (B) the
                           aggregate consideration for such maximum number of
                           Additional Shares of Common Stock shall be deemed to
                           be the minimum consideration received or receivable
                           by the Corporation for the issuance of such
                           Additional Shares of Common Stock pursuant to such
                           warrants or other rights or pursuant to the terms of
                           such Convertible Securities. For the purposes of this
                           subsection (d)(iii), the date as of which the Current
                           Market Price per share of Common Stock shall be
                           computed shall be the earliest of (I) the date on
                           which the Corporation shall take a record of the
                           holders of its Common Stock for the purpose of
                           entitling them to receive any such warrants or other
                           rights, (II) the date on which the Corporation shall
                           enter into a legally binding contract for the
                           issuance of such warrants or other rights or (III)
                           the date of actual issuance of such warrants or other
                           rights. Such reduction shall be made successively
                           whenever such a record date is fixed, a legally
                           binding contract for the issuance of such warrants or
                           other rights is entered or such warrants or other
                           rights are issued. In the event that such rights or
                           warrants are not so issued or (if issued) to the
                           extent not exercised, the Conversion Ratio shall
                           again be adjusted to be the Conversion Ratio, as the
                           case may be, which would then be in effect if such
                           record date had not been fixed or such unexercised
                           rights or warrants had not been issued.

                  (iv)     In case at any time, or from time to time, the
                           Corporation shall take a record of the holders of its
                           Common Stock for the purpose of entitling them to
                           receive a distribution, by dividend or otherwise, of
                           evidences of its indebtedness or assets (including
                           securities, but excluding (A) any dividend or
                           distribution referred to in subsection (d)(i) hereof
                           and (B) any dividend or distribution paid in cash out
                           of funds legally available therefor of the
                           Corporation), then in each such case the Conversion
                           Ratio in effect after such record date shall be
                           determined by multiplying the Conversion Ratio, in
                           effect immediately prior to such record date by a
                           fraction, of which the numerator shall be the total
                           number of

                                       6

                           outstanding shares of Common Stock multiplied by the
                           Current Market Price on such record date, less the
                           fair market value (as determined by the Board of
                           Directors of the Corporation, whose determination
                           shall be conclusive) of the portion of the assets or
                           evidences of indebtedness so to be distributed, and
                           of which the denominator shall be the total number of
                           outstanding shares of Common Stock multiplied by such
                           Current Market Price. Such adjustment shall be made
                           successively whenever such a record date is fixed. In
                           the event that such distribution is not so made, the
                           Conversion Ratio shall again be adjusted to be the
                           Conversion Ratio which would then be in effect if
                           such record date had not been fixed.

                  (v)      No adjustment in the Conversion Ratio shall be
                           required unless such adjustment would require an
                           increase or decrease of at least one percent (1%) in
                           such Conversion Ratio; provided, however, that any
                           adjustment which by reason of this paragraph
                           subsection (d)(v) is not required to be made shall be
                           carried forward and taken into account in any
                           subsequent adjustment. All calculations under this
                           subsection (d) shall be made to the nearest cent or
                           to the nearest 1/100 of a share, as the case may be.

         (e)      NO IMPAIRMENT. The Corporation will not, by amendment of its
                  Articles of Incorporation or through any reorganization,
                  transfer of assets, consolidation, merger, dissolution, issue
                  or sale of securities or any other voluntary action, avoid or
                  seek to avoid the observance or performance of any of the
                  terms to be observed or performed hereunder by the
                  Corporation, but will at all times in good faith assist in the
                  carrying out of all the provisions of this Section 3 and in
                  the taking of all such action as may be necessary or
                  appropriate in order to protect the conversion rights of the
                  holders of the Series D Preferred Stock against impairment.

         (f)      NOTICE PROVISIONS.

                  (i)      Whenever the Conversion Ratio shall be adjusted
                           pursuant to subsection (d) hereof, the Corporation
                           shall forthwith obtain a certificate signed by the
                           Corporation's chief financial officer, setting forth,
                           in reasonable detail, the event requiring the
                           adjustment and the method by which such adjustment
                           was calculated (including a description of the basis
                           on which the Corporation's independent public
                           accountants determined the fair value of any
                           evidences of indebtedness, shares of stock, other
                           securities or property or assets or warrants or other
                           subscription or purchase rights referred to in
                           subsections (d)(ii) through (d)(v) hereof) and
                           specifying the new Conversion Ratio and (if
                           applicable) describing the amount and kind of common
                           stock, securities, property or assets or cash which
                           may be received upon conversion of the Series D
                           Preferred Stock, after giving effect to such
                           adjustment. The Corporation shall promptly cause a
                           signed copy of such certificate to be delivered to
                           each holder of Series D Preferred Stock.

                  (ii)     In case the Corporation shall propose (A) to pay any
                           dividend payable in stock of any class to the holders
                           of its Common Stock or to make any other distribution
                           to the holders of its Common Stock, (B) to offer to
                           the holders of its Common Stock rights to subscribe
                           for or to purchase any Convertible Securities or
                           Additional Shares of Common Stock or shares of stock
                           of any class or any other securities, rights or
                           options, (C) to effect any reclassification of its
                           Common Stock (other than a reclassification involving
                           only the subdivision or combination of outstanding
                           shares of Common Stock), (D) to effect any capital
                           reorganization, (E) to effect any consolidation,
                           merger or sale, transfer or other distribution of all
                           or substantially all its property, assets or
                           business, or (F) to effect the liquidation,
                           dissolution or winding-up of the Corporation, then in
                           each such case, the Corporation shall give to each
                           holder of Series D Preferred Stock a notice of such
                           proposed action, which shall specify the date on
                           which a record is to be taken for the purposes of
                           such stock dividend, distribution or rights, or the
                           date on which such reclassification, reorganization,
                           consolidation, merger, sale, transfer, disposition,
                           liquidation, dissolution or winding-up is to take
                           place and the date of participation therein by the
                           holders of Common Stock, if any such date is to be
                           fixed, and shall also set forth such facts with
                           respect thereto as shall be reasonably necessary to
                           indicate the effect of such action on the Common
                           Stock and the Conversion Ratio after giving effect to
                           any adjustment which will be required as a result of
                           such action. Such notice shall be so given in the
                           case of any action covered by (A) or (B) above at
                           least 20 days prior to the record date for
                           determining holders of the Common Stock for purposes
                           of such action and, in the case of any other such
                           action, at least 20 days prior to the date of the
                           taking of such proposed action or the date of
                           participation therein by the holders of Common Stock,
                           whichever shall be the earlier.

         (g)      TREASURY STOCK. The sale or other disposition of any issued
                  shares of Common Stock owned or held by or for the account of
                  the Corporation shall be deemed an issuance thereof for
                  purposes of subsection (d) hereof, but until so issued such
                  shares shall not be deemed to be outstanding.

         (h)      COMPUTATION OF CONSIDERATION. To the extent that any
                  Additional Shares of Common Stock or any Convertible
                  Securities or any warrants or other rights to subscribe for or
                  purchase any Additional Shares of Common Stock or any
                  Convertible Securities shall be issued for a cash
                  consideration, the consideration received by the Corporation
                  therefor shall be deemed to be the amount of the cash received
                  by the Corporation therefor, or, if such Additional Shares of
                  Common Stock or Convertible Securities are offered by the
                  Corporation for subscription, the subscription price, or, if
                  such Additional Shares of Common Stock or Convertible
                  Securities are sold to underwriters or dealers for public
                  offering without a subscription offering, the initial public
                  offering price, in any such case excluding any amounts paid or
                  receivable for accrued interest or accrued dividends and
                  without deduction of any compensation, discounts or expenses
                  paid or incurred by the Corporation for and in the
                  underwriting of, or otherwise in connection with, the issue
                  thereof. To the extent that such issuance shall be for a

                                       8

<PAGE>


                  consideration other than cash, then, except as herein
                  otherwise expressly provided, the amount of such consideration
                  shall be deemed to be the fair value of such consideration at
                  the time of such issuance as determined by the Board of
                  Directors of the Corporation. The consideration for any
                  Additional Shares of Common Stock issuable pursuant to any
                  warrants or other rights to subscribe for or purchase the same
                  shall be the consideration received by the Corporation for
                  issuing such warrants or other rights, plus the additional
                  consideration payable to the Corporation upon the exercise of
                  such warrants or other rights. The consideration for any
                  Additional Shares of Common Stock issuable pursuant to the
                  terms of any Convertible Securities shall be the consideration
                  received by the Corporation for issuing any warrants or other
                  rights to subscribe for or purchase such Convertible
                  Securities, plus the consideration paid or payable to the
                  Corporation in respect of the subscription for or purchase of
                  such Convertible Securities, plus the additional
                  consideration, if any, payable to the Corporation upon the
                  exercise of the right of conversion or exchange in such
                  Convertible Securities. In case of the issuance at any time of
                  any Additional Shares of Common Stock or Convertible
                  Securities in payment or satisfaction of any dividend upon any
                  class of stock other than Common Stock or in payment of any
                  debt, the Corporation shall be deemed to have received for
                  such Additional Shares of Common Stock or Convertible
                  Securities a consideration equal to the amount of such
                  dividend or debt so paid or satisfied.

         (i)      FRACTIONAL INTERESTS. In computing adjustments under this
                  Section 3, fractional interests in Common Stock shall be taken
                  into account to the nearest one-hundredth of a share.

         (j)      ANTIDILUTION PROVISIONS. No adjustment shall be made as a
                  result of any increase in the number of Additional Shares of
                  Common Stock issuable or any decrease in the consideration
                  payable upon any issuance of Additional Shares of Common
                  Stock, pursuant to any provisions intended solely to avoid
                  dilution contained in any warrants, rights or Convertible
                  Securities.

         (k)      WHEN ADJUSTMENT NOT REQUIRED.

                  (i)      If the Corporation shall take a record of the holders
                           of its Common Stock for the purpose of entitling them
                           to receive a dividend or distribution or subscription
                           or purchase rights and shall, thereafter and before
                           the distribution to stockholders thereof, legally
                           abandon its plan to pay or deliver such dividend,
                           distribution, subscription or purchase rights, then
                           thereafter no adjustment shall be required by reason
                           of the taking of such record and any such adjustment
                           previously made in respect thereof shall be rescinded
                           and annulled.

                  (ii)     If the Corporation declares or makes any dividend or
                           distribution with respect to Common Stock, other than
                           regular cash dividends or dividends payable solely in
                           shares of Common Stock, and each holder of Series D
                           Preferred Stock concurrently receives dividends or
                           distributions equal in amount and in the same kind of
                           property (whether cash, securities or other property)
                           as such

                                       9

<PAGE>


                           holder would be entitled to receive if all of the
                           outstanding Series D Preferred Stock were converted
                           into Common Stock as of the record date of such
                           dividend or distribution with respect to Common
                           Stock, then thereafter no adjustment shall be
                           required with respect to such dividend or
                           distribution.

         (l)      OTHER ACTION AFFECTING COMMON STOCK. If a state of facts shall
                  occur which, without being specifically controlled by the
                  other provisions of this Section 3, would not fairly protect
                  the conversion rights of the Series D Preferred Stock in
                  accordance with the essential intent and principles of such
                  provisions, then the Board of Directors of the Corporation
                  shall in good faith make an adjustment in the application of
                  such provisions, in accordance with such essential intent and
                  principles, so as to protect such conversion rights.

         (m)      NECESSARY CORPORATE ACTION. Before taking any action which
                  would result in an adjustment in the Conversion Ratio, the
                  Corporation shall obtain all such authorizations or exemptions
                  thereof, or consents thereto, as may be necessary from any
                  public regulatory body or bodies having jurisdiction thereof.

         (n)      TAXES UPON CONVERSION. The Corporation shall pay all
                  documentary, stamp or other transaction taxes attributable to
                  the issuance or delivery of shares of Common Stock upon
                  conversion of any shares of Series D Preferred Stock.

         (o)      RESERVATION OF COMMON STOCK. The Corporation shall at all
                  times reserve and keep available out of its authorized but
                  unissued shares of Common Stock solely for the purpose of
                  effecting the conversion of shares of Series D Preferred
                  Stock, the full number of whole shares of Common Stock then
                  deliverable upon the conversion of all shares of Series D
                  Preferred Stock at the time outstanding. All shares of Common
                  Stock which shall be so issuable shall, when issued upon
                  conversion of all or any portion of the Series D Preferred
                  Stock, be duly and validly issued and fully paid and
                  non-assessable and free from all taxes, liens and charges with
                  respect to the issuance thereof. Upon conversion of Series D
                  Preferred Stock, the shares of Series D Preferred Stock so
                  converted shall have the status of authorized and unissued
                  Preferred Stock, and the number of shares of Series D
                  Preferred Stock which the Corporation shall have authority to
                  issue shall be decreased by any such conversion.

         (p)      DIVIDENDS CONSTITUTE CORPORATE DEBT. All dividends accrued and
                  unpaid on Series D Preferred Stock to and including the date
                  of conversion, whether or not declared by the Board of
                  Directors, shall constitute a debt of the Corporation payable
                  without interest to the converting holders and shall be paid
                  by the Corporation in cash on the Conversion Date.

4.       NO PREEMPTIVE RIGHTS. No holder of Series D Preferred Stock shall have
         any preemptive or preferential right of subscription to any shares of
         stock of the Corporation, or to options, warrants or other interests
         therein or therefor, or to any obligations convertible into stock of
         the Corporation, issued or sold, or any right of subscription to any
         thereof other than such, if any, as the Board of Directors, in its
         discretion, from time to time may determine and at such price

                                       10

<PAGE>


         or prices as the Board of Directors from time to time may fix pursuant
         to the authority conferred by the Corporation's Articles of
         Incorporation.

5.       CERTAIN RESTRICTIONS. So long as any Series D Preferred Stock is
         outstanding, the Corporation shall not, without the consent of holders
