standing under the laws of its jurisdiction of incorporation and has all
requisite corporate power and authority to conduct its business as currently

standing in each jurisdiction in which the failure to so qualify would have a
material adverse effect on the operations of the Company and its subsidiaries,
taken as a whole.

     4.2. Authorized Capital Stock. 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)
3,333,340 shares of Series B Convertible Preferred Stock of which 666,668 are
outstanding and 6,666,660 shares of undesignated preferred stock of which none
are outstanding.

     4.3. Due Execution, Delivery and Performance of the Agreement. The Company
has full power and authority to enter into this Agreement and each of the
Documents. This Agreement has been, and each Document and the Bonds will be,
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
subsidiaries is a party or by which the Company or any of its subsidiaries or
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

     4.4. Issuance, Sale and Delivery of the Bonds, Series C Preferred Stock and
Common Stock. When executed and delivered by the Company, the Bonds, Series C
Preferred Stock and Common Stock will constitute valid and legally binding
obligations of the Company enforceable against the Company in accordance with

principles of equity (regardless of whether such enforceability is
considered in a proceeding at equity or at law). Upon issuance, the Series C
Preferred Stock, Warrants and Underlying Common Stock will be duly authorized
and validly issued and, upon payment therefor, will be non-assessable.

     4.5. Litigation. There is no action, suit or proceeding before or by 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.

     4.6. Exchange Act Reports; No Material Misstatement or Omission. The
Company has timely filed all periodic reports required to be filed under the
Securities Exchange Act of 1934 ("Exchange Act Reports"). As of their respective
dates, the Company's Exchange Act Reports do not contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

     4.7. No Material Change. Save as disclosed in the Company's Exchange Act
Reports and on Schedule 4.7 attached hereto, 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 declared any dividends or other distributions on their capital stock;

debt or, any 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
such opinion were addressed directly to such Purchaser.

Purchaser is entitled which certificates shall be legended as provided in the
Form of Convertible Bond. The Company shall issue its Common Stock upon exercise
of the Warrants in accordance with the terms of the Warrant Agreement which

defined in the Registration Rights Agreement) is declared effective by the
Securities and Exchange Commission, if any holder of Underlying Common Stock
shall deliver to the Company 's transfer agent (i) the certificate

                                       4

          THE PLAN OF DISTRIBUTION SET FORTH IN THE PROSPECTUS.

                                  SCHEDULE 4.7

1.   SECOND QUARTER, 1999 OPERATING LOSS

     The Company experienced an operating loss of approximately $1,050,000 in
the second quarter, 1999. Approximately $250,000 of this loss was attributable
to the closing of the Company's St. Paul, Minnesota, facility and to other
restructuring charges.

2.   CONTINUED LOSSES LIKELY

     The Company anticipates that it will continue to experience significant
losses through the third quarter, 1999. The Company believes that its operating
losses will narrow appreciably in the fourth quarter, 1999 and that the Company
may achieve break-even operations during this quarter. However, the Company
cannot offer any assurances as to whether, or the extent to which, its operating
results will improve.

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 August 15, 2000 in the
aggregate principal amount of $800,000 (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 C 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) 3,333,340 shares


<PAGE>

Board of Directors
August 16, 1999
Page 2

of Series B Convertible Preferred Stock of which 666,668 shares are outstanding
and 6,666,660 shares of undesignated preferred stock of which none are
outstanding.

     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 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,

     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 __________________________________________ (the
"Bondholder"), or registered assigns, the principal sum of ______________ United
States Dollars on August 15, 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 is payable. 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. The Company shall make
twenty-three (23) interest only payments under the Bond each of which shall be
due on or before the 15th day of each month beginning on September 15, 1999. The
Company shall make a final payment consisting of the entire balance of principal
and accrued but unpaid interest on or before August 15, 2000. If any payment is
due on a Saturday or Sunday, or on any national holiday on which commercial
banks are not open for normal business, such payment shall be made on the next
succeeding business day. 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 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 $800,000 in principal amount, maturing August 15, 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")
irrespective of the dates or order of filing thereof or the dates or order of
filing 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 sum 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

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 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.

<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 three (3) 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 C Preferred Stock, $.01 par value, set forth in the
Purchase Agreement ("Series C 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 C
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 C 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

                                       4

<PAGE>

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

     (c) The "Unit Purchase Price" shall be the lower of: (a) $1.7188, or (b)
the average of the closing bid price of the Company's Common Stock on the Nasdaq
SmallCap Market for the ten (10) trading days including and immediately
following August 2, 1999.

     (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 C Preferred Stock and exercise of the Warrants.

3.   CONVERSION.

     (a) On the Conversion Date the Bonds 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 C
Preferred Stock authorized no later than three (3) 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,

                                       5

<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

                                       6

<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

                                       7

<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.

                                       8

<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
the date of maturity or the date fixed for redemption, and no interest shall
accrue for the period after such date.

prescribe, the Company shall provide for the registration of Bonds and of

other good and valuable consideration, and intending to be legally bound hereby,
the parties agree as follows:

                                       1

<PAGE>


     1. COLLATERAL. For purposes of this Agreement, "Collateral" means all
property now owned or hereafter acquired by Debtors and any and all inventory,
supplies, accounts receivable, machinery, equipment, tools, fixtures,
furnishings, furniture, books, records, charts, analyses, compilations, contract
rights, reports, any and all other personal property and goods, any and all
general intangibles, trade secrets, intellectual property, trademarks (and all

     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.

     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, and (ii) interests of record as of the date
     hereof.

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

                                       2

<PAGE>


          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.

          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

                                       3

<PAGE>

     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:

          principal under the Bonds when due; or

               (2) Derma Sciences fails to have a sufficient number of shares of
          Series C Preferred Stock authorized no later than three (3) days after
          the Conversion Notification Date (as defined in the Bonds) to permit
          conversion of the Bonds; or

               (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

                                       4

<PAGE>

          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 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

                                       5

<PAGE>

          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 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

                                       6

<PAGE>

     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 and legal expenses
     incurred or paid by the Secured Parties in protecting or enforcing their
     rights, powers and remedies hereunder or under any other agreement between
     the parties or under any obligation secured hereby or thereby.

          6. MISCELLANEOUS.

          a. Amendment and Waiver. The provisions of this Agreement may be
     amended or compliance with this Agreement waived only by the written
     agreement of the Secured Parties and the Debtors.

          b. Titles. The titles and section headings herein are included for
     convenience only and shall not be deemed to be a part of this Agreement.

          c. Cumulative Rights. Each and every right granted to the Secured
     Parties hereunder or under any other document delivered hereunder or in
     connection herewith or allowed by law or equity shall be cumulative and may
     be exercised from time to time. No failure on the part of the Secured
     Parties to exercise, and no delay in exercising, any right shall operate as
     a waiver thereof, nor shall any single or partial exercise by the Secured
     Parties of any right preclude any other or future exercise thereof or the

     amendments or supplements thereto, furnish to the Holders covered by such
     Registration Statement a copy of all such documents proposed to be filed,
     which documents will be subject to the review of such Holders, and the
     Company will not file any Registration Statement or amendment thereto or
     any Prospectus or any supplement thereto to which the Holders 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 Holder within five business days after delivery
     of such documents to such Holder);

          (b) prepare and file with the SEC such amendments and post-effective
     amendments to the Registration Statement, and such supplements to the
     Prospectus, as may be required by the rules, regulations or instructions
     applicable to the registration form utilized by the Company or by the
     Securities Act or rules and regulations thereunder or otherwise necessary
     to keep the Registration 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 Registrable
          Securities for sale in any jurisdiction or 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;

     Holder, at least one conformed copy of the Registration Statement and any
     post-effective amendment thereto, including financial statements and
     schedules, all documents

                                       4

<PAGE>

     incorporated therein by reference and all exhibits (including those
     incorporated by reference);

          (f) deliver to each Purchaser and each Holder without charge, as many
     copies of the Prospectus (including each preliminary prospectus) and any
     amendment or supplement thereto as such Persons may reasonably request; the
     Company consents to the use of the Prospectus or any amendment or
     supplement thereto by each Purchaser 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 or approved by
     such governmental agencies or authorities as may be necessary to enable the
     Holders thereof to consummate the disposition 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 representative, all
     financial and other records, pertinent corporate 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-

                                       5

<PAGE>

     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 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
Expenses") incident to the Company's performance of or compliance with this
Agreement will be borne by the Company, regardless of whether the Registration
Statement becomes effective:

          (1) all registration, filing and listing fees;

          (2) fees and expenses of counsel acceptable to the Holders of a
     majority of the Registrable Securities for compliance with securities or
     blue sky laws;

          (3) the Company's printing, messenger, telephone and delivery
     expenses;

<PAGE>


          (5) fees and disbursements of all independent certified public
     accountants of the Company (including the expenses of any special audit
     necessary to satisfy the requirements of the Securities Act); and

          (6) fees and expenses associated with any NASD filing required to be
     made in connection with the Registration Statement.

     The Company will, in any event, pay its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the securities to
be registered on the Boston Stock Exchange and the Nasdaq SmallCap Market.

     6. INDEMNIFICATION AND CONTRIBUTION.

          (a) Indemnification by the Company. The Company agrees to indemnify
     and hold harmless each Holder, its officers, directors, employees and
     agents and each Person who controls such Holder within the meaning of
     either Section 15 of the Securities Act or Section 20 of the Exchange Act
     (each such person being sometimes hereinafter referred to as an
     "Indemnified Holder") from and against all losses, claims, damages,
     liabilities and expenses (including reasonable costs of investigation and
     legal expenses) arising out of or based upon any untrue statement or
     alleged untrue statement of a material fact contained in any Registration
     Statement or Prospectus or in any amendment or supplement thereto or in any
     preliminary prospectus, or arising out of or based upon any omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading;
     provided, however, that the Company will not be liable in any such case to
     the extent that any such losses, claims, damages, liabilities or expenses
     arise out of or are based upon any untrue statement or alleged untrue
     statement or omission or alleged omission thereof based upon information
     furnished in writing to the Company by such Holder or its agent expressly
     for use therein; provided further, that the Company shall not be liable in
     any such case to the extent that any such loss, claim, damage, liability or
     expense arises out of or is based upon an untrue statement or alleged
     untrue statement or omission or alleged omission in the Prospectus, if such
     untrue statement or alleged untrue 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

                                       7

<PAGE>

     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 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,

                                       8

<PAGE>

     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 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

                                       9

<PAGE>

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. 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).

                                       10

<PAGE>


          (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.

          (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.

                          THE SERIES OF PREFERRED STOCK

                                       OF

                              DERMA SCIENCES, INC.

                                TO BE DESIGNATED

                      SERIES C 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 C Convertible Preferred Stock" (the "Series C 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 C Preferred Stock, as
follows:

1.   VOTING RIGHTS. The holders of Series C 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 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 C 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 C 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 C Preferred Stock shall be entitled to receive the
     purchase price per share (the "Liquidation

                                        1

<PAGE>

     Preference"), together with accrued and unpaid dividends payable thereon to
     the date fixed for 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 C Preferred Stock (and any series of preferred
     stock ranking in parity with the Series C 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 C 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
     and Series B Convertible Preferred Stock shall rank in parity with the
     Series C Preferred Stock. After payment of the full amount of the
     liquidating distribution to which they are entitled, the holders of Series
     C 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 C Preferred Stock or the qualifications, limitations or
     restrictions thereof in a manner that adversely affects the Series C
     Preferred Stock.

3.   CONVERSION RIGHTS.

     (a)  CONVERSION OF SERIES C PREFERRED STOCK. Each share of Series C
          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 C
          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 C 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

                                        2

<PAGE>

          (609) 452-0880, Attention: Edward J. Quilty, shall be deemed notice
          for purposes of 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 C 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 C 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 legend:

                           THE SHARES  REPRESENTED BY THIS  CERTIFICATE HAVE NOT
                           BEEN REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS
                           AMENDED. THE SHARES HAVE BEEN ACQUIRED FOR INVESTMENT
                           AND MAY NOT BE SOLD,  TRANSFERRED  OR ASSIGNED IN THE
                           ABSENCE OF EITHER AN EFFECTIVE REGISTRATION STATEMENT
                           FOR THESE SHARES UNDER THE SECURITIES ACT OF 1933, AS
                           AMENDED,  OR AN OPINION OF COUNSEL THAT  REGISTRATION
                           IS NOT  REQUIRED  UNDER  SAID ACT.  THESE  SHARES ARE
                           SUBJECT TO CERTAIN  REGISTRATION  RIGHTS AS SET FORTH
                           IN A  REGISTRATION  RIGHTS  AGREEMENT A COPY OF WHICH
                           MAY BE OBTAINED FROM THE CORPORATION.

          If the Registration Statement (as defined in the Registration Rights
          Agreement) has been declared effective by the Securities and Exchange
          Commission, the certificate(s) evidencing the Conversion Shares will
          bear the following legend:

                           THE SHARES  REPRESENTED BY THIS CERTIFICATE HAVE BEEN
                           REGISTERED  UNDER  THE  SECURITIES  ACT OF  1933,  AS
                           AMENDED.  THE  SHARES  MAY BE  SOLD  PURSUANT  TO THE

                                        3

<PAGE>


                           REGISTRATION   STATEMENT  PROVIDED  THAT  THE  HOLDER
                           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 C 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 C 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 C 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 C Preferred Stock. If
          more than one share of Series C 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 C
          Preferred Stock so surrendered. Instead of any fractional shares of
          Common Stock which would otherwise be issuable upon conversion of any
          shares of Series C 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

                                        4

<PAGE>

               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 C Preferred Stock surrendered for conversion
               after such time shall be entitled to receive the aggregate number
               and kind of shares which, if such Series C 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

                                        5

<PAGE>

               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

                                        6

<PAGE>

               date by a fraction, of which the numerator shall be the total
               number of 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 C 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 C 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 C
               Preferred Stock.

                                        7

          (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 C
               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 C 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 C 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 C 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 C 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 C Preferred Stock, the full number of whole shares of
          Common Stock then deliverable upon the conversion of all shares of
          Series C 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 C 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 C Preferred Stock, the shares of Series C
          Preferred Stock so converted shall have the status of authorized and
          unissued Preferred Stock, and the number of shares of Series C
          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 C 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 C 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,
