"Prime Rate Loan".

                             (b)     Reduced Rate.  Notwithstanding the
foregoing, commencing after December 31, 1997, upon the Bank's receipt of
Borrowers' quarterly or annual Financial Statements in accordance with Section
6.2.1 hereof, demonstrating that the Borrowers' Consolidated Debt Service
Coverage Ratio for the immediately preceding consecutive four (4) fiscal
quarters exceeded 1.5 to 1, and provided there is no existing Event of Default
hereunder, the interest rate for the LIBOR Rate Loan shall be reduced to the
LIBOR Rate plus 2.5% per annum and the interest rate for the Prime Rate Loan
shall be reduced to the Bank's Prime Rate (collectively, the "Reduced Interest
Rates"). The Reduced Interest Rates shall remain in effect only so long as
there is no Event of Default under this Agreement and only so long as the
Borrowers' Consolidated Debt Service Coverage Ratio for any subsequent period
of four (4) consecutive quarterly periods continues to exceed 1.5 to 1.  If the
Borrowers' Consolidated Debt Service Coverage Ratio for any subsequent period
of four (4) consecutive quarterly periods fails to exceed 1.5 to 1, then the
Original Interest Rates shall be reinstated until the subsequent achievement of
the conditions for the application of the Reduced Interest Rates upon which the
Reduced Interest Rates shall be reinstated.  Any change in the Original
Interest Rates or the Reduced Interest Rates under this Subsection shall become
effective on the first day of the calendar month immediately following the
Bank's receipt of





                                     - 9 -

<PAGE>   14
Financial Statements demonstrating the requisite change, provided, however,
that in the case of a LIBOR Rate Loan, the change in the rate shall become
effective on the first Business Day immediately following the expiration of the
Interest Period then in effect for the LIBOR Rate Loan.

                             (c)     Payment.  Interest on the Term Loan shall
be payable with respect to a Prime Rate Loan or a LIBOR Rate Loan, monthly in
arrears on the first Business Day of each month during the term of the Term
Loan.

                             (d)     Computation.  All computation of interest
hereunder shall be made on the actual number of days elapsed over a year of 360
days.

                             (e)     Default Rate.  If an Event of Default
shall have occurred and be continuing, interest shall be paid at the default
rate in accordance with Section 2.6 hereof.

                  2.3.2      Conversion Option.  Subject to the
provisions of this Section, the Borrowers shall have the option to convert at
any time, all but not part of the Term Loan, from a Prime Rate Loan or LIBOR
Rate Loan into the other or upon expiration of any Interest Period applicable
to a LIBOR Rate Loan to continue such Loan as a LIBOR Rate Loan and the
Interest Period of such continued Loan shall commence on the last day of the
Interest Period of the Loan to be continued; provided that except as otherwise
provided in Section 2.3.4 a LIBOR Rate Loan may be converted into a Prime Rate
Loan or continued as a LIBOR Rate Loan only on the last day of an Interest
Period applicable thereto.   Each such conversion (or continuation) shall be
effected by an Authorized Officer or Officers of the Borrowers giving the Bank
prior to noon (New York time) at least three (3) Business Days (or the same
Business Day in the case of a conversion to a Prime Rate Loan) prior written
notice (or telephonic notice promptly confirmed in writing) (each a "Notice of
Continuance/Conversion") substantially in the form of Exhibit B hereto,
specifying the type of Term Loan to be converted into and (after being
converted into or continued as a LIBOR Rate Loan), the Interest Period to be
initially applicable thereto. If no Notice of a Continuance/Conversion has been
delivered with respect to a LIBOR Rate Loan on or before the third Business Day
prior to the last day of the Interest Period applicable thereto, such LIBOR
Rate Loan shall be automatically converted to a Prime Rate Loan.

                  2.3.3      Interest Periods.  At the time the
Borrowers give a Notice of Continuance/Conversion in respect of the making of,
continuance of, or conversion into, a LIBOR Rate Loan, it shall have the right
to elect, by giving the Bank written notice (or telephonic notice promptly
confirmed in writing), the Interest Period, which Interest Period shall, at the
option of Borrower, be a one, two or three month period.  Notwithstanding
anything to the contrary contained herein:

                             (a)     If any Interest Period relating to a LIBOR
Rate Loan begins on a date for which there is no numerically corresponding date
in the calendar month in which such Interest Period ends, such Interest Period
shall end on the last Business Day of such calendar month;

                             (b)     If any Interest Period would otherwise
expire on a day which is not a Business Day, such Interest Period shall expire
on the next succeeding Business Day; provided, that if any Interest Period in
respect of a LIBOR Rate Loan would otherwise expire on a day which is not a
Business Day but is a day of the month after which no further Business Day
occurs in such month, such Interest Period shall expire on the next preceding
Business Day; and

                             (c)     No Interest Period shall extend beyond the
Maturity Date.

                  2.3.4      Special Provisions Applicable to LIBOR Rate.

                             (a)     The LIBOR Rate may be automatically
adjusted by the Bank on a retroactive basis to take into account (but only to
the extent necessary to recover such additional or increased costs) the
additional or increased cost of maintaining any necessary reserves for
Eurodollar deposits or increased cost due to any change in applicable law or
regulation or the interpretation thereof by any governmental authority charged
with the administration thereof or the introduction of any law or regulation
occurring subsequent to the commencement of the then applicable Interest
Period, including but not limited to changes in tax laws (except changes of
general applicability in corporate income tax laws) and changes in the reserve
requirements imposed by the Board of Governors of the Federal Reserve System
(or any successor), that increases the cost to the Bank of funding a LIBOR Rate
Loan.  The Bank shall give the Borrowers notice of such a determination and
adjustment and the Borrowers may, by





                                     - 11 -

<PAGE>   16
notice to the Bank: (x) require the Bank to furnish to the Borrowers a
statement setting forth the basis for adjusting such LIBOR Rate and the method
for determining the amount of such adjustment; and/or (y) may either (i) if a
Notice of Continuance/Conversion has been given with respect to the affected
LIBOR Rate Loan, cancel said notice by giving Bank telephonic notice (confirmed
promptly in writing) thereof on the same date Borrowers was notified pursuant
to this subsection, or (ii) if the affected LIBOR Rate Loan is still
outstanding, upon at least three Business Days' notice to the Bank, require the
Bank to convert each such LIBOR Rate Loan into a Prime Rate Loan, or prepay
such LIBOR Rate Loan; provided, that the Borrower shall compensate the Bank as
set forth in Section 2.3.4(d) hereof.

                             (b)     In the event that the Bank shall have
reasonably determined that Eurodollar deposits equal to the amount of the LIBOR
Rate Loan requested, for the Interest Period specified, are unavailable or that
a LIBOR Rate will not adequately and fairly reflect the cost of making or
maintaining such LIBOR Rate Loan during the Interest Period specified or, that
by reason of circumstances affecting Eurodollar markets, adequate and
reasonable means do not exist for ascertaining a LIBOR Rate applicable to the
specified Interest Period, the Bank shall promptly give notice of such
determination to the Borrowers that a LIBOR Rate Loan is not available, and any
Notice of Continuance/Conversion given by the Borrowers with respect to
borrowing, conversion or continuance of a LIBOR Rate Loan which have not been
incurred shall be deemed rescinded by the Borrowers.  A determination by the
Bank pursuant to this subsection shall be conclusive.

                             (c)     In the event that it becomes unlawful for
the Bank to maintain Eurodollar liabilities sufficient to fund a LIBOR Rate
Loan, then the Bank shall notify the Borrowers and the Bank's obligation
hereunder to advance or maintain a LIBOR Rate Loan shall be suspended until
such time as the Bank may again offer a LIBOR Rate Loan.  If the affected LIBOR
Rate Loan is still outstanding, the Bank shall require, as promptly as
practicable, that the Borrower either:  (i) convert each such LIBOR Rate Loan
into a Prime Rate Loan, or (ii) prepay such LIBOR Rate Loan; provided, that the
Borrower shall compensate the Bank as set forth in Section 2.3.4(d) hereof.

                             (d)     The Borrowers shall compensate the Bank,
upon written request by the Bank, for reasonable losses, expenses and
liabilities (including, without limitation, such





                                     - 12 -

<PAGE>   17
factors as any interest paid by the Bank to lenders of funds borrowed by it to
make or carry a LIBOR Rate Loan and any loss sustained by the Bank in
connection with re-employment of such funds based upon the difference between
the amount earned in connection with re-employment of such funds and the amount
payable by Borrowers if such funds had been borrowed or remained outstanding)
which the Bank may sustain with respect to the Borrowers' LIBOR Rate Loan:  (i)
if for any reason (other than a default or error by the Bank) a LIBOR Rate Loan
does not occur on a date specified therefor in a Notice of
Continuance/Conversion or in a telephonic request for conversion, or a
successive Interest Period in respect of any such LIBOR Rate Loan does not
commence after notice thereof is given pursuant to Section 2.3.2, (ii) if any
prepayment (under Section 2.4) or conversion of any LIBOR Rate Loan to the
Borrowers occurs on a date which is not the last day of the Interest Period
applicable to the Term Loan, (iii) if any prepayment of any such LIBOR Rate
Loan to the Borrowers is not made on any date specified in a notice of
prepayment given by the Borrowers, and (iv) any other failure by the Borrowers
to repay a LIBOR Rate Loan when required by the terms of this Agreement,
including an election by Borrowers made pursuant to this subsection; provided,
however, that the Borrowers shall not be required to compensate the Bank to the
extent such losses, expenses and liabilities have already been recovered by the
Bank pursuant to Section 2.3.4(a).

                  2.3.5      Usury.  If at any time the interest rate
being charged to the Borrowers under this Agreement or the Term Note shall be
deemed by any governmental authority to exceed the maximum rate of interest
permitted by applicable law, then, without affecting the validity or
enforceability of this Agreement or any part hereof or the Term Note, such rate
shall be reduced to the maximum rate permissible under such applicable law.  If
the Bank has received any payment of interest which exceeded the maximum legal
rate, then such amount shall, at the option of the Bank, be applied to the
reduction of the unpaid principal balance (and not to the payment of interest)
or returned to the Borrowers.

            SECTION 2.4      Prepayment.  (a)  The Borrowers shall have the
right to prepay the Term Loan in whole, or in part (in increments equal to
quarterly installments), at any time  and from time to time upon not less than
ten (10) days prior written notice to the Bank of Borrowers' intention to
prepay.  If the Term Loan is a Prime Rate Loan at the time of prepayment, the
prepayment shall include all accrued and unpaid interest on the





                                     - 13 -

<PAGE>   18
principal amount of the Term Loan so paid through the prepayment date, but
shall not include any premium or penalty.  If the Term Loan is a LIBOR Rate
Loan at the time of prepayment, any prepayment of the Term Loan shall include
the payment of all accrued and unpaid interest on the principal amount so paid,
plus a premium equal to the amount, if any, by which (i) the installments of
principal being prepaid plus the installments of interest which would have been
payable thereon when discounted to a present value at a rate per annum equal to
the yield to maturity of the Applicable Treasury Bond Obligation exceeds (ii)
the principal amount being prepaid.  As used herein, "Applicable Treasury Bond
Obligation" means the debt obligation of the United States Treasury having a
maturity date nearest in time to the last day of an Interest Period applicable
thereto.  The maturity date and yield to maturity of such Applicable Treasury
Bond Obligation shall be determined by the Bank in its sole discretion on the
basis of quotations published in the Wall Street Journal on the date of
prepayment.  The Bank shall notify the Borrowers in a timely manner of the
amount of such premium owed to the Bank and the basis of its calculation.

            SECTION 2.5      Compensation for Certain Contingencies.

                  2.5.1      Taxes, Reserves and Expenses on Loans.  If any
law, regulation, treaty or official directive, or the interpretation or
application thereof by any court or by any governmental authority charged with
the administration thereof, or the compliance with any guideline or request
from any central bank or other governmental authority (whether or not having
the force of law) (a) subjects the Bank to any tax or changes the basis of
taxation with respect to payments of principal, interest or other amounts due
from Borrowers (except for taxes, fees or other charges based on, or measured
by, the income or profits of the Bank (or the relevant lending office or
offices) or any franchise taxes or similar taxes imposed in lieu thereof); (b)
imposes, modifies or deems applicable any reserve, special deposit, premium, or
similar requirement against assets held by, or deposits in or for the account
of, or loans or commitments by, the Bank; or (c) imposes upon the Bank any
other condition with respect to this Agreement; and the result of any of the
foregoing is to increase the cost to the Bank, reduce the income receivable by
the Bank or impose any expense upon the Bank with respect to the Term Loan by
an amount which has not resulted or been reflected in an increase in the
interest rate(s) applicable to the Term Loan or otherwise recovered pursuant to
Section 2.3.4 and the Bank deems to be material, the Bank shall from time to





                                     - 14 -

<PAGE>   19
time notify Borrowers; and Borrowers shall pay to the Bank, within thirty (30)
Business Days after receipt of such notice, that amount which shall compensate
the Bank (on an after-tax basis) for such increase in cost, reduction in income
or additional expense.  The Bank's computation of the amount necessary to
compensate it shall be (i) set forth in reasonable detail, along with the basis
therefor, in a certificate which shall accompany the Bank's notice to Borrowers
of any such amount, (ii) made in good faith with a reasonable basis, and (iii)
conclusive in the absence of manifest error.

                  2.5.2      Capital Adequacy.  If (a) the introduction of, or
any change in, or in the interpretation of, any United States law, rule or
regulation or (b) compliance with any directive, guidelines or request from any
central bank or other United States or foreign governmental authority (whether
or not having the force of law) promulgated or made after the date hereof
affects or would affect the amount of capital required or expected to be
maintained by the Bank or any corporation directly or indirectly owning or
controlling the Bank, and the Bank shall have determined that such
introduction, change or compliance has or would have the effect of reducing the
rate of return on the Bank's capital or on the capital of such owning or
controlling corporation as a consequence of its obligations hereunder to a
level below that which the Bank or such owning or controlling corporation could
have achieved but for such introduction, change or compliance (after taking
into account the Bank's policies or the policies of such owning or controlling
corporation, as the case may be, regarding capital adequacy) by an amount
deemed by the Bank (in its sole discretion) to be material, which has not been
reflected in the interest rate(s) applicable to the Loans or otherwise
recovered pursuant to Section 2.3.4, then, from time to time Borrowers shall
pay to the Bank within thirty (30) Business Days after receipt of notice from
the Bank of any change described in this Section such amount as shall
compensate the Bank for any such change.  The Bank's computation of the amount
necessary to compensate it shall be (i) set forth in reasonable detail, along
with the basis therefor, in a certificate which shall accompany the Bank's
notice to Borrowers of any such amount, (ii) made in good faith with a
reasonable basis, and (iii) conclusive absent manifest error.

            SECTION 2.6      Default Interest.  Following any Event of Default
hereunder and while such Event of Default is continuing, Borrowers shall pay
interest on (a) the outstanding principal balance of the Term Loan and (b) to
the extent permitted by law,





                                     - 15 -

<PAGE>   20
on all overdue portions of interest on the Term Loan and all such other overdue
amounts owing to the Bank outstanding up to the date of actual payment (after
as well as before judgment) at a rate equal to 3% per annum above the Original
Interest Rate for the LIBOR Rate Loan or Prime Rate Loan, then in effect.

            SECTION 2.7      Deduction of Payment.  Any principal, interest,
fees or other Obligations payable by Borrowers hereunder shall be deducted by
the Bank and paid from the Borrowers' operating  accounts described in Section
6.9 hereof as and when due from time to time; provided, however, that the Bank
shall give Borrowers reasonable prior notice of its intent to so deduct funds
other than interest (including default interest), principal and any fees
related to the Bank's duties pursuant to Section 2.9 below.

            SECTION 2.8      Closing. The Term Loan will be closed at the
offices of Dechert, Price & Rhoads, Princeton Pike Corporate Center, 997 Lenox
Drive, Building 3, Suite 210, Lawrenceville, New Jersey, or any other location
agreed upon by the Borrowers and the Bank. Closing of the Term Loan shall occur
no later than August 29, 1997.

            SECTION 2.9      Structuring Fee.  A loan structuring fee of
$40,000 shall be paid by the Borrowers to the Bank on the Closing Date (the
"Structuring Fee").  If Chrysalis International Corporation ("Chrysalis"),
however, engages CoreStates Investment Advisors on the Closing Date, to act as
its sole cash investment advisor and primary depository for the investment
business of its excess corporate funds and the excess corporate funds of the
other Borrowers for the term of the Term Loan on mutually satisfactory terms,
the Bank shall refund the Structuring Fee to Chrysalis.  If Chrysalis forgoes
any right to the refund of the Structuring Fee and engages another cash
investment advisor and primary depository for such excess corporate funds and
the excess corporate funds of the other Borrowers, provided such other entity
must be based in the United States and be reasonably satisfactory to the Bank,
the Bank shall be entitled to a first lien in all such corporate funds of the
Borrowers, and such other entity shall enter into such security arrangements
with the Bank as the Bank may deem necessary or appropriate, including, without
limitation, the following:

                             (a)     An acknowledgment and confirmation of the
Bank's first priority lien in all such corporate funds of the Borrowers;





                                     - 16 -

<PAGE>   21
                             (b)     Arrangements for the delivery to the Bank
of detailed reports no less often than monthly, dated as of a recent date,
setting forth a complete description of the following:

                                       (i)  account and investment balances,

                                      (ii)  the types and amounts of investment
securities,

                                     (iii)  name of depositary, location and
account numbers for all accounts containing funds of investment of Borrowers,
and any foreign or domestic Subsidiaries, and

                                      (iv)  all loan balances and short-term
borrowings, including all intercompany advances or investments (whether foreign
or domestic); and

                             (c)     Upon the occurrence of an Event of Default
under this Agreement, provision for the immediate delivery to the Bank (through
wire transfer or other means acceptable to the Bank) of corporate funds of the
Borrowers in an amount equal to the Cash Collateral.

                                   ARTICLE 3
                              COLLATERAL SECURITY

            SECTION 3.1      Collateral.  As security for the performance of
this Agreement and for the prompt and complete payment of the Term Note when
due (whether at the Maturity Date, by acceleration or otherwise), and as
security for all other existing and future indebtedness of the Borrowers to the
Bank, the Borrower hereby grants to the Bank a first priority lien on and
security interest in all of the assets of the Borrowers located in the United
States (excluding the Permitted Liens)  including, without limitation, the
following, whether now owned or after-acquired (the "Collateral"):

                             (a)     all of Borrowers' existing and future
accounts receivable, chattel paper, instruments, contract rights, investment
accounts (including, without limitation, the investment accounts described in
Section 2.5 herein), documents, rights to the payment of money (including
patent and other license fees and royalties), inventory, goods, machinery and
equipment, fixtures and all other personal property and all proceeds, including
insurance proceeds, of the foregoing;

<PAGE>   22
                             (b)     all of Borrowers' general intangibles,
including, without limitation, all right, title and interest of the Borrowers
in and to all patents (including, without limitation, the exclusive license to
the microinjection patent), copyrights, licenses, royalty fees, service marks,
tradenames and trademarks, rights to file and prosecute applications for
patents, copyrights and trademarks, and similar intellectual property anywhere
in the world and the good will of the business connected with the use of and
symbolized by any patents, licenses, copyrights, service marks, trade names and
trademarks, together with all assets which reflect the good will of the
business of the Borrowers, including, but not limited to, the Borrowers' trade
names, customer lists, trade secrets, corporate and other business records,
advertising materials, operating, sales and programming manuals, methods,
processes, and know-how, sales literature, drawings, specifications,
descriptions, inventions, catalogues, copyrights, confidential information; and

                             (c)     a pledge to the Bank of all outstanding
stock of all direct and indirect subsidiaries, both foreign and domestic, of
Chrysalis.

            SECTION 3.2      Collateral Reports. The Borrowers shall provide to
the Bank detailed quarterly reports regarding accounts receivable from domestic
operations and licensing operations in form and substance satisfactory to the
Bank.  In addition, the Borrowers shall provide to the Bank within ten (10)
days of the end of each calendar month a report disclosing the Borrowers' and
Subsidiaries' cash balances and borrowings under lines of credit or other
credit facilities for such month, both domestic and foreign, in form and
substance satisfactory to the Bank.  The Borrowers' obligation to provide the
monthly reports described in the preceding sentence shall be suspended upon
delivery to the Bank of Financial Statements of the Borrowers' demonstrating
that the Borrowers' and Subsidiaries' Consolidated Net Income for the four (4)
immediately preceding consecutive fiscal quarters exceeds $1,000,000 and
provided the Borrowers are not in default under this Agreement.  The Borrowers'
obligation to deliver such monthly reports shall be reinstated immediately upon
the Borrowers' failure to demonstrate Consolidated Net Income in excess of
$1,000,000 for any such four (4) quarter period.

            SECTION 4.1      Conditions Precedent to the Term Loan.  The
obligation of the Bank to fund the Term Loan shall be subject to the prior or
concurrent fulfillment of each of the following conditions precedent.

                  4.1.1      Fees.  Borrowers shall have paid, or made

pursuant to Section 8.4).

                  4.1.2      Representations.  The following statements
shall be true and the making of the Term Loan hereunder shall be deemed to be a

                         REPRESENTATIONS AND WARRANTIES

            SECTION 5.1      Representations and Warranties of the Borrowers.
Each Borrower hereby jointly and severally represents and warrants as follows:

                  5.1.1      Existence.  Each Borrower is a corporation
duly organized, validly existing and in good standing under the laws of its
state of incorporation in the jurisdictions set forth in the first paragraph on
Page 1 hereof.





                                     - 21 -

<PAGE>   26
                  5.1.2      Corporate Authorizations.  Each Borrower
(a) has all requisite corporate power and authority to conduct its business as
now conducted and as presently contemplated to be conducted, and to consummate
the transactions contemplated hereby and by any Loan Document to which it is or
will be a party and (b) is duly qualified to do business and is in good
standing in each jurisdiction in which the character of the properties owned or
leased by it or in which the transaction of its business makes such
qualification necessary.

                  5.1.3      Capitalization and Indebtedness.

                             (a)     The authorized and issued stock of
Chrysalis International Corporation ("Chrysalis") is as set forth in its
Quarterly Report on Form 10-Q for the quarter ended June 30, 1997. All of the
issued stock of each other Borrower is owned beneficially and of record by
Chrysalis.  All of such issued and outstanding shares of capital stock of each
Borrower have been duly authorized, validly issued and are fully paid and
non-assessable.  Except as disclosed in the Definitive Proxy Statement of
Chrysalis dated April 30, 1997, no Borrower has outstanding any rights,
options, warrants, conversion rights or agreements for the purchase or
acquisition from such Borrower of any shares of their capital stock.

                             (b)     Schedule 5.1.3 correctly lists all
outstanding Indebtedness for which each Borrower is liable or to which each
Borrower is a party, whether or not indebtedness is outstanding thereunder, and
the maximum amounts of indebtedness which may be incurred thereunder, and there
have heretofore been delivered to the Bank complete and correct copies of all
agreements and other instruments relating to such Indebtedness.

                  5.1.4      No Violation.  The execution, delivery and
performance by each Borrower of each Loan Document to which it is or will be a
party, (a) are within its corporate powers, (b) have been duly authorized by
all necessary corporate action, (c) do not and will not contravene its charter
or by-laws, any law or governmental regulation or any contractual restriction
(other than a restriction with respect to which the Borrowers have secured a
valid waiver or consent) binding on or affecting it or any of its properties,
and (d) do not and will not result in or require the creation of any lien,
security interest or other charge or encumbrance (other than pursuant to any
such Loan Document) upon or with respect to any of its properties, whether now
owned or hereafter acquired.

                  5.1.5      Authorizations and Approvals.  Except for
the waivers and consents obtained by the Borrowers with respect for the PIDA
and PNC Loans, no authorization or approval or other action by, and no notice
to or filing with, any governmental authority or other regulatory body is
required for the due execution, delivery and performance by any Borrower of any
Loan Document to which it is or will be a party.

                  5.1.6      Validity.  This Agreement is, and each other Loan
Document to which each Borrower is or will be a party, when delivered
hereunder, will be, a legal, valid and binding obligation of such Borrower,
enforceable against it in accordance with its terms, except as the
enforceability thereof may be limited by bankruptcy, insolvency, moratorium and
other laws affecting creditors rights generally and except as may be limited by
equitable principles.

                  5.1.7      Pending Litigation.  There is no action, suit or
proceeding pending or to the knowledge of the Borrowers threatened against or
otherwise affecting any Borrower before any court, arbitrator or governmental
department, commission, board, bureau, agency or instrumentality, which would
have a Material Adverse Effect.

                  5.1.8      Financial Statements.  The audited annual
consolidated and consolidating financial statements of Chrysalis and its
Consolidated Subsidiaries, dated as of December 31, 1996, and the unaudited
quarterly financial statements of Chrysalis and its Consolidated Subsidiaries,
dated March 31, 1997 fairly present the financial condition of the Borrowers,
as at the respective dates thereof and the results of operations of the
Borrowers described therein for the fiscal periods ended on such respective
dates, all in accordance with generally accepted accounting principles
consistently applied (subject to normal year-end audit adjustments in the case
of interim financial statements).

                  5.1.9      Solvency.  The Borrowers taken as a whole (both
before and after giving effect to the transactions contemplated hereby) are
solvent, have assets (including goodwill) having a fair saleable value in
excess of the amount required to pay their consolidated probable liabilities on
existing debts as they become absolute and matured, and have, and will have,
access to adequate capital for the conduct of their business and the ability to
pay their debts from time to time incurred in connection therewith as such
debts mature.

                  5.1.10     Margin Securities.  No Borrower is or will be
engaged in the business of extending credit for the purpose of purchasing or
carrying margin stock (within the meaning of Regulation U issued by the Board
of Governors of the Federal Reserve System), and no proceeds of the Term Loan
will be used to purchase or carry any margin stock or to extend credit to
others for the purpose of purchasing or carrying any margin stock.

                  5.1.11     Taxes.  All Federal, state and local tax returns
and other reports required by applicable law to be filed have been filed, and
all taxes, assessments and other governmental charges imposed upon each
Borrower and which have become due and payable on or prior to the date hereof
have been paid except (a) insofar as extensions have been obtained and are
currently in effect and (b) to the extent contested in good faith by proper
proceedings which stay the imposition of any penalty, fine or lien resulting
from the non-payment thereof and with respect to which adequate reserves have
been set aside for the payment thereof or (c) except as to income taxes,
withholding taxes or sales taxes, where the failure to file such returns or
reports or pay such taxes would not have a Material Adverse Effect.

                  5.1.12     Compliance with Laws and Agreements.  No Borrower
is in violation of (a) its charter or by-laws, (b) any law, governmental
regulation, order or judgment or (c) any term of any agreement or instrument
(other than with respect to which the Borrowers have secured a valid waiver or
consent) binding on or affecting it or any of its properties except insofar as
such violation would not, in the case of clauses (b) and (c), have a Material
Adverse Effect.

                  5.1.13     Liens.  Each Borrower has good and marketable
title to all of its properties and assets and such properties and assets are
free and clear of all liens, security interests and other charges and
encumbrances and other types of preferential arrangements except for Permitted
Liens.

                  5.1.14     Patents and Trademarks.  Each Borrower owns or has
sufficient rights to use all the patents, trademarks, copyrights, licenses and
rights necessary for the present and planned future conduct of their respective
businesses, without any known conflict with the rights of others.

                  5.1.15     Restrictions on Borrowers. No Borrower is a party
to any contract or agreement, or subject to any charter or





                                     - 24 -

<PAGE>   29
other corporate restriction, which would have a Material Adverse Effect.  No
Borrower has agreed or consented to cause or permit in the future (upon the
happening of a contingency or otherwise) any of the property of any such
corporation, whether now owned or hereafter acquired, to be subject to a lien,
other than Permitted Liens.

                  5.1.16     Investment Company Act.  No Borrower is an
"investment company" registered or required to be registered under the
Investment Company Act of 1940, as amended, nor is it controlled by an
"investment company".

                  5.1.17     The Security Documents.   The provisions of the
Security Documents are effective to create in favor of the Bank, a legal, valid
and enforceable security interest in all right, title and interest of each
Borrower in the Collateral except as the enforceability thereof may be limited
by bankruptcy, insolvency, moratorium and other laws affecting creditors rights
generally and except as may be limited by equitable principles; upon the proper
filing of financing statements as required by the applicable Uniform Commercial
Code the Security Documents shall constitute a fully perfected first lien on,
and security interest in all right, title and interest of such Borrower in the
Collateral described therein to the extent the filing of financing statements
under the Uniform Commercial Code are permissible methods of perfection of
security interests in the Collateral described therein in each such
jurisdiction, subject to no prior liens, except Permitted Liens.

                  5.1.18     ERISA.  Each Pension Plan has complied and has
been administered in all material respects, in accordance with applicable
provisions of ERISA and the Internal Revenue Code.  Neither the Borrowers nor
any Commonly Controlled Entity has, as of the date hereof, or during the
immediately preceding six-year period, has had any obligation to contribute to
any Multiemployer Plan.  For purposes of the Section, "Pension Plan" means any
"employee pension plan" as defined in Title 3 of ERISA, maintained by
Borrowers; "Multiemployer Plan" means a Pension Plan which is a multiemployee
plan as defined in Section 4001(a)(3) of ERISA; and "Commonly Controlled

of this Section, any former or current Affiliate or Subsidiary of each
Borrower) is now and has been in compliance with all Environmental Laws, except
where the failure to be in compliance would not, individually or in the
aggregate, have a Material Adverse Effect.

                             (b)     No toxic, hazardous or polluting
substances or wastes ("Hazardous Substances") have been released, discharged or
disposed of, spilled, leaked, pumped, poured, emitted, emptied, injected,

Environmental Laws, at, on, or under any property now owned or occupied by any
Borrower, or during such time as any Borrower formerly owned or occupied any

                             (c)     No Borrower has received from any federal,

for clean-up costs, remedial work, damages to natural resources or for personal
injury claims, including, but not limited to, claims under CERCLA.

                             (e)     There have been no environmental

certificates, licenses, inspections, consents and franchises necessary to
continue to conduct its business and to own or lease and operate its properties
as heretofore conducted, owned, leased or operated and as presently
contemplated to be conducted, owned, leased or operated, except where the
failure to be so current or in good standing would not have a Material Adverse
Effect.

hereof, giving effect to the consummation of the transactions contemplated by
the Loan Documents, there exists no actual or, to Borrowers' knowledge,

with any material supplier to such Borrower or such Borrower's predecessors,

Closing Date.

become delinquent all taxes, assessments and governmental charges or levies
imposed upon it or upon its income or profits or its properties, and paying all

Effect except to the extent contested in good faith by proper proceedings which
stay the imposition of any penalty, fine or lien resulting from the non-payment
thereof and with respect to which adequate reserves have been set aside for the
payment thereof and such contest will not in the reasonable judgment of the
Bank endanger its interest in any Collateral.

            SECTION 6.4      Preservation of Existence, Etc.  Each Borrower
will maintain and preserve its existence, rights and privileges, except that
any Borrower may merge with another Borrower, and become or remain duly

qualified will not have a Material Adverse Effect.

obtain, maintain and preserve all permits, licenses, authorizations, approvals
and accreditations necessary or useful in the proper conduct of its business,

tear excepted, and (b) comply at all times with the provisions of all leases to

in any of the cases described in the foregoing clauses (a) through (d), the
Bank further reasonably determines that the "amount of unfunded guaranteed
benefits" (as defined by Section 4001(a)(17) of ERISA) resulting upon
termination of such Employee Plan or the amount of liability resulting from the
withdrawal from any such Multiemployer Plan would have a Material Adverse
Effect; or

or more of the following:  (a) declare the Term Note, all interest thereon and
all other amounts payable under this Agreement to be forthwith due and payable,
whereupon the Term Note, all such interest and all such amounts shall become
and be forthwith due and payable, without presentment, demand, protest or
further notice of any kind, all of which are hereby expressly waived by
Borrowers; (b) exercise any and all of its other rights under applicable law,
hereunder and under the other Loan Documents; and (c) require the Borrowers to
deposit with the Bank cash collateral ("Cash Collateral") consisting of cash
and marketable securities in an amount at least equal to (a) the outstanding
balance of all Obligations due under the Term Loan minus (b) the sum of (i) 50%
of Borrowers' Eligible Accounts Receivable as of a recent date, plus (ii) the
aggregate amount of cash received by Borrowers in the immediately preceding
Fiscal Year from microinjection revenues, license fees and royalty fees,
provided, however, that all one-time, non-recurring and other lump sum payments
made during such Fiscal Year shall be excluded from the calculation of the cash
received by Borrowers from such revenues and fees.  For purposes hereof,
"Eligible Accounts Receivable" shall mean Borrowers' rights to payment for
goods sold or services rendered in the ordinary course of business to
non-Affiliated parties, but excluding receivables which are more than ninety
(90) days past due, chargebacks, ineligible account debtors (as reasonably
determined by the Bank), accounts of any

ineligible by the Bank; provided, that no notice need be given to any Borrower
upon the occurrence of any Event of Default described in Section 7.1.7 and the
Obligations shall be automatically accelerated.

                     7.1.15  Non-Waiver.  The remedies provided herein, and in
any other Loan Document or otherwise available to the Bank at law or in equity,
and any warrants of attorney therein contained, shall be cumulative and
concurrent, and may be pursued singly, successively or together at the sole
discretion of Bank, and may be exercised as often as occasion therefor shall
occur; and the failure to exercise any such right or remedy shall in no event
be construed as a waiver or release of the same.

            SECTION 8.3      No Waiver; Remedies, Etc.  No failure on the part
of the Bank to exercise, and no delay in exercising, any right hereunder or
under any other Loan Document shall operate as a waiver thereof; nor shall any
single or partial exercise of any right under any Loan Document preclude any
other or further exercise thereof or the exercise of any other right.  The
rights and remedies of the Bank provided herein and in the other Loan Documents
are cumulative and are in addition to, and not exclusive of, any rights or
remedies provided by law.  The rights of the Bank under any Loan Document
against any party thereto are not conditional or contingent on any attempt by
the Bank to exercise any of its rights under any other Loan Document against
such party or against any other Person.

            SECTION 8.4      Fees, Costs, Expenses and Taxes.  Whether or not
the Term Loan is made hereunder or the transactions contemplated hereby are
consummated, Borrowers will pay on demand all fees, costs and expenses in
connection with the preparation, execution, delivery, filing, and recording of
the Loan Documents and the other documents to be delivered under the Loan
Documents, including, without limitation, the reasonable fees, out-of-pocket
expenses and other reasonable disbursements of Dechert Price & Rhoads, counsel
to the Bank, and of any other counsel retained by the Bank with respect thereto
and with respect to advising the Bank as to its rights and responsibilities
under the Loan Documents (provided that such legal fees are not to exceed
$15,000 and shall be paid from the Committment Fee previously paid by Borrowers
pursuant to Section 4.1.1), and all costs and expenses, if any, in connection
with any waiver or amendment of any Loan Document or in connection with the
enforcement of the Loan Documents and the other documents to be delivered under
the Loan Documents and in connection with any inspection conducted by the Bank.
In addition, Borrowers will pay any and all stamp and other taxes and fees
payable or determined to be payable in connection with the execution, delivery,
filing and recording of the Loan Documents and the other documents to be
delivered under the Loan Documents, and will save the Bank harmless from and
against any and all liabilities with respect to or resulting from any delay in
paying or omission to pay such taxes and fees.

            SECTION 8.5      Indemnity.  Each Borrower agrees to indemnify the
Bank and its Affiliates, directors, officers, employees, agents and controlling
persons against, and to hold the Bank and each such Person harmless from, any
and all losses, claims, damages, liabilities and related expenses, including
reasonable counsel fees and expenses, incurred by or asserted





                                     - 43 -

<PAGE>   48
against the Bank or any such Persons arising out of, in any way in connection
with, or as a result of (i) this Agreement, any of the Loan Documents and the
other documents contemplated hereby or thereby, the performance by the parties
hereto and thereto of their respective obligations hereunder and thereunder and
consummation of the transactions contemplated hereby and thereby, or (ii) any
claim, litigation, investigation or proceeding relating to any of the
foregoing, whether or not the Bank or any such Person is a party thereto, or
(iii) breach of any representation, warranty or covenant hereof, or (iv)
environmental conditions, including without limitation, the presence of
Hazardous Substances at, on, under or within any property owned or occupied by
Borrowers, the Release or threat of Release of Hazardous Substances at such
property whether into the air, soil, ground or surface waters, or any
Environmental Complaint (as defined in Section 6.17); provided, however, any
such indemnity provided for in clause (i) through (iv) above shall not as to
the Bank, apply to any such losses, claims, damages, liabilities or related
expenses arising from its bad faith, gross negligence or wilful misconduct.
Borrowers agree to respond on the Bank's behalf to any matter subject to
subsections (iii) and (iv) above or, at the Bank's election, to pay the costs
of the Bank's response. Borrowers hereby waive and release the Bank from any
and all losses, claims, damages, and liabilities, known or unknown, foreseen or
unforeseen, which exist or which may arise in the future under common or
statutory law, including CERCLA or any other Environmental Laws now or
hereafter in effect.  The provisions of this Section shall remain operative and
in full force and effect regardless of the expiration of the term of this
Agreement or any other of the Loan Documents, the repayment of the Term Loan,
the invalidity or unenforceability of any term or provision of this Agreement,
the Term Note or any other Loan Document, or any investigation made by or on
behalf of the Bank.  All amounts due under this Section shall be payable on
written demand therefor.

            SECTION 8.6      Right of Set-off.  Upon occurrence and during the
continuance of any Event of Default and the declaration by the Bank that the
Term Note is due and payable, the Bank may, and is hereby authorized at any
time and from time to time, without notice to Borrowers (any such notice being
expressly waived by Borrowers) and to the fullest extent permitted by law, to,
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by the Bank to or for the credit or the account of Borrowers against any and
all





                                     - 44 -

<PAGE>   49
obligations of Borrowers now or hereafter existing under this Agreement and the
Term Note held by the Bank, irrespective of whether or not the Bank shall have
made any demand under this Agreement or the Term Note and although such
obligations may be contingent or unmatured.  The Bank agrees promptly to notify
Borrowers after any such set-off and application made by the Bank, provided
that the failure to give such notice shall not affect the validity of such
set-off and application.  The rights of the Bank under this Section are in
addition to other rights and remedies (including, without limitation, other
rights of set-off) which the Bank may have.


            SECTION 8.7      Severability of Provisions.  Any provision of this
Agreement, or of any other Loan Document, which is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the
extent of such prohibition or invalidity without invalidating the remaining
portions hereof or thereof or affecting the validity or enforceability of such
provision in any other jurisdiction.

            SECTION 8.8      Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of each Borrower, and the Bank and their
respective successors and assigns, except that neither Borrower shall have the
right to assign its rights hereunder or any interest herein without the prior
written consent of the Bank.

            SECTION 8.9      Assignment and Participation.

                             (a)     The Bank shall have the right from time to
time to assign to one or more assignees all or any portion of its commitment to
make loans to in its interest in the Obligations of the Borrowers hereunder and
correspondingly delegate its duties thereunder; provided, however, that such
consent of Borrowers shall not be required if an Event of Default has occurred
and is continuing.

                             (b)     The Bank may sell participations to one or
more banks or other financial institutions in all or a portion of its rights
and obligations under this Agreement (including, without limitation all or a
portion of its Commitment, the advances owing to it and the Obligations held by
it); provided, however, that (a) the Bank's obligations under the Loan
Documents remain unchanged, (b) the Bank shall remain solely responsible to the
other parties for performance of such





                                     - 45 -

<PAGE>   50
obligations, (c) the Bank shall remain the holder of any Note for all purposes
of this Agreement, (d) the Borrower shall continue to deal solely and directly
with the Bank in connection with the Bank's rights and obligations under this
Agreement and (e) the Bank shall not grant participants any voting rights
except as such rights relate to changes in interest rates, fees, amounts of
payments or terms of payments.

            SECTION 8.10     Counterparts.  This Agreement may be executed in
two or more counterparts, each of which shall be deemed an original, but all of
which taken together shall constitute one and the same instrument.

            SECTION 8.11     Waiver of Jury Trial; Consent to Jurisdiction.

                             (a)     EXCEPT AS PROHIBITED BY LAW, EACH PARTY
HERETO WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH
THIS AGREEMENT, ANY OF THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY.

                             (b)     EACH BORROWER IRREVOCABLY SUBMITS AND
CONSENTS TO THE NON-EXCLUSIVE JURISDICTION OF A STATE OR FEDERAL COURT SITTING
IN PENNSYLVANIA OVER ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE
LOAN DOCUMENTS, AND EACH BORROWER HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN
RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH
PENNSYLVANIA STATE OR FEDERAL COURT.  EACH BORROWER AGREES THAT SERVICE OF
COPIES OF ANY SUMMONS AND COMPLAINT AND ANY OTHER PROCESS WHICH MAY BE SERVED
IN ANY SUCH ACTION MAY BE MADE BY MAILING BY REGISTERED MAIL OR DELIVERING A
COPY OF SUCH PROCESS TO EACH BORROWER AT THE ADDRESS SPECIFIED IN SECTION 8.1.

            SECTION 8.12     Governing Law.  This Agreement and the Term Note
shall be governed by, and construed in accordance with, the law of
Pennsylvania.

            SECTION 8.13     Termination.  Upon the payment and satisfaction of
all principal, interest, fees and other sums due and owing under this Agreement
and termination of the Commitments hereunder or release of the Obligations,
this Agreement, except for the provisions of Section 8.5 hereof, shall
terminate and the Bank's liens on the Collateral will be released.

            SECTION 8.14     Joint and Several Liability.  Each Borrower agrees
that the obligations of the Borrowers hereunder are joint and several.  Each
Borrower acknowledges that it is substantially dependent upon the other
Borrowers, and that a loan to any Borrower directly benefits the other
Borrowers in providing sufficient inventory and capital for all Borrowers.

            SECTION 8.15     Entire Agreement.  This Agreement and the
agreements referred to herein contain the entire agreement and understanding of
the parties hereto respecting the subject matter hereof, and supersede and
replace all prior agreements and understandings with respect thereto, whether
written or oral.
