Agent such corresponding amount, such amount so repaid shall constitute such
Holder's purchase of a Note of the relevant Tranche for purposes of this

      (e) On the Closing Date, against payment as set forth in subsection (c) of
this Section, each Issuer shall deliver to the Paying Agent, with respect to

Business Days after the date of any receipt by DNAP after the date hereof of

Amounts, as the case may be, which, together with all other Savia Prepayment
Amounts or DNAP Prepayment Amounts not previously so applied, respectively, are
greater than $1,000,000, and (ii) if no Notes can then be prepaid without the
Issuer thereof incurring costs pursuant to Section 2.08, such Savia Prepayment
Amount or DNAP Prepayment Amount, as the case may be, may instead be pledged
with the Paying Agent on terms satisfactory to the Paying Agent and such
prepayment may be deferred to the last day of the Interest Period applicable to
such Notes next ending after the date of such receipt.

      (f) Each prepayment of the Notes pursuant to subsections (c) or (d) shall

Holders in proportion to the aggregate outstanding principal amounts of such
Notes; provided that any prepayment pursuant to subsection (c) after the date on
which all scheduled repayments required by subsection (b) above have been made
(or reduced to $0 pursuant to the last sentence thereof) shall be applied first
to the repayment of Tranche A Notes and second, after the Tranche A Notes have
been repaid in full, to the Tranche B Notes, in each case in proportion to the
aggregate outstanding principal amounts of the Notes of such Tranche. Each
prepayment of the Notes pursuant to subsection (c) made on or prior to the

Prepayment Amount, as the case may be) pursuant to subsections (c) or (d).

Administrative Agent and the Paying Agent, prepay or redeem the Notes of such
Issuer, in whole at any time, or from time to time in part in principal amounts
aggregating $5,000,000 or any larger multiple of $1,000,000, by paying the
principal amount of such Notes to be prepaid or redeemed together with accrued
interest thereon to the date of prepayment plus, in the case of any prepayment
of the Tranche B Notes, the Applicable Premium Amount of such Tranche B Notes
for the date on which such prepayment is made. Each such optional prepayment
shall be applied to prepay ratably the Notes of each Tranche of the Issuer
making such prepayment then outstanding (in the case of Savia, the Tranche A
Notes and the Tranche B Notes), in proportion to the aggregate outstanding
principal amounts of such Notes.

      (b) Upon receipt of a notice of prepayment pursuant to this Section, the
Paying Agent shall promptly notify each Holder of the contents thereof and of
such Holder's ratable share of such prepayment and such notice shall not
thereafter be revocable by the Issuer.

      SECTION 2.07. General Provisions as to Payments. (a) Each Issuer shall 
make each payment of principal of, and interest and premium on, the Notes and 
of fees hereunder, not later than 10:00 a.m. (New York City time) on the date 
when due, in Federal or other funds immediately available in New York City, 
to the Paying Agent at its address referred to in Section 10.01. The Paying 
Agent will promptly distribute to each Holder its ratable share of each such 
payment received by the Paying Agent for the account of the Holders. Whenever 
any payment of principal of, or interest or premium on, any Note shall be due 
on a day which is not a Euro-Dollar Business Day, the date for payment 
thereof shall be extended to the next succeeding Euro-Dollar Business Day 
unless such Euro-Dollar Business Day falls in another calendar month, in 
which case the date for payment thereof shall be the next preceding 
Euro-Dollar Business Day. If the date for any payment of principal is 
extended by operation of law or otherwise, interest thereon shall be payable 
for such extended time.

      (b) Unless the Administrative Agent and the Paying Agent shall have
received notice from an Issuer prior to the date on which any payment is due to
the Holders hereunder from such Issuer that such Issuer will not make such
payment in full, the Paying Agent may assume that such Issuer has made such
payment in full to the Paying Agent on such date and the Paying Agent may, in
reliance upon such assumption, cause to be distributed to each Holder on such
due 


                                       31
<PAGE>

date an amount equal to the amount then due such Holder. If and to the extent
that such Issuer shall not have so made such payment, each Holder shall repay to
the Paying Agent forthwith on demand such amount distributed to such Holder
together with interest thereon, for each day from the date such amount is
distributed to such Holder until the date such Holder repays such amount to the
Paying Agent, at the Federal Funds Rate.

      SECTION 2.08. Funding Losses. If an Issuer makes any payment of principal
with respect to any Note or a Note is required to bear interest at the
Alternative Rate (pursuant to Article 2, 6, 8 or otherwise) on any day other
than the last day of an Interest Period applicable thereto, or if any Issuer
fails to issue or prepay any Notes after notice has been given to any Holder in
accordance with Sections 2.02(b), 2.04(h) or 2.06(b), such Issuer shall
reimburse each Holder within 15 days after demand for any resulting loss or
expense incurred by it (or by an existing or prospective Participant in the
related Note), including (without limitation) any loss incurred in obtaining,
liquidating or employing deposits from third parties, but excluding loss of
margin for the period after any such payment or failure to issue or prepay;
provided that such Holder shall have delivered to such Issuer a certificate as
to the amount of such loss or expense, which certificate shall be conclusive in
the absence of manifest error.

      SECTION 2.09. Computation of Interest and Fees. Interest based on the 
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or 
366 days in a leap year) and paid for the actual number of days elapsed 
(including the first day but excluding the last day). All other interest, 
premium and fees shall be computed on the basis of a year of 360 days and 
paid for the actual number of days elapsed (including the first day but 
excluding the last day).

connection with any Financing Document or any transaction contemplated thereby
is, and all such information hereafter furnished by either Issuer or any of its
Subsidiaries or any Affiliates to the Administrative Agent or the Paying Agent,
on behalf of the Holders, will be, true and accurate in all material respects on
the date as of which such information is stated or certified. Such Issuer has
disclosed to the Holders in writing any and all facts which have or may have a
Material Adverse Effect on such Issuer (to the extent such Issuer can now
reasonably foresee) or which may adversely affect such Issuer's ability to
perform its obligations under the Financing Documents to which it is a party.

      SECTION 4.12. Solvency. As of the Closing Date, after giving effect to the
transactions contemplated by the Financing Documents (including, without
limitation, the issuance of the Notes by each Issuer), such Issuer and each
grantor (fideicomitente) under each of the Mexican Trust Agreements is solvent
(within the meaning of applicable Mexican law or United States law, as the case
may be), and no event or combination of events (including, without limitation,
any pending or threatened litigation) has occurred which could reasonably be
expected to draw such solvency into question.

      SECTION 4.13. No Restrictions on Dividends. No Subsidiary of Savia is
party to, bound by or otherwise subject to, any agreement with any Person which
prohibits or limits the ability of such Subsidiary to (i) pay dividends or make
other distributions, (ii) pay any Debt owed to Savia or any other Subsidiary or
(iii) make loans or advances to Savia or any other Subsidiary, other than the
agreements governing Debt of any Subsidiary of Savia not prohibited by Section
5.10, as in effect on the date hereof.

      SECTION 4.14. Listing of Shares. All SCA Shares and all Empaques Shares
issued and outstanding as of the Closing Date have been duly listed on the Bolsa
Mexicana in accordance with the rules and regulations thereof. All DNAP Shares
issued and outstanding as of the Closing Date have been duly listed on NASDAQ,
in accordance with the rules and regulations thereof.

      SECTION 4.15. Insurance Industry or Regulatory-Specific Representations.
SCA and its Subsidiaries are in compliance in all respects with all applicable
laws and regulatory requirements of the CNSF and the Ministry of Finance and any
other regulatory authority having jurisdiction over any of them, except for such
non-compliance which could not reasonably be expected to have a Material Adverse
Effect with respect to SCA.

      SECTION 4.16. Legal Form; No Immunity. (a) Each of the Financing Documents
is in proper legal form under all applicable laws for the enforcement thereof in
accordance with its terms against the parties thereto under such laws. To ensure
the legality, validity, enforceability or admissibility into evidence of the


                                       41
<PAGE>

Financing Documents, it is not necessary that any of such Financing Documents or
any other document be filed or recorded with any governmental body, agency or
official or that any stamp or similar tax be paid on or in respect of such
Financing Document or other document, except that if any legal proceedings are
brought in the courts of Mexico, a Spanish translation of the documents required
in such proceedings prepared by a court-approved translator would have to be
approved by the court after the defendant had been given an opportunity to be
heard with respect to the accuracy of the translation, and proceedings would
thereafter be based on the translated documents.

      (b) Neither of the Issuers or any of its respective Subsidiaries or any of
their respective revenues, assets or properties have any right of immunity, on
the ground of sovereignty or otherwise, from service of process or the
jurisdiction of any court in connection with any suit, action or proceeding
arising out of or relating to its obligations under the Financing Documents or
from the execution or enforcement of any judgment resulting therefrom, and if
either Issuer or any of its revenues, assets or properties should become
entitled to any such right of immunity, such Issuer has effectively waived such
right pursuant to Section 10.12.

      (c) It is not necessary (i) in order for the Administrative Agent, the
Paying Agent, the Collateral Agents or any Holder to enforce any rights or
remedies under the Financing Documents or (ii) solely by reason of the
execution, delivery and performance by either Issuer of the Financing Documents,
that any Agent or any Holder be licensed or qualified with any governmental
body, agency or official or be entitled to carry on business in any
jurisdiction.

      SECTION 4.17. Collateral Documents; Collateral. (a) Each of the
representations and warranties contained in the Collateral Documents is true and
correct.

      (b) The provisions of each Collateral Document, subject to performance in
accordance therewith, are effective to create in favor of the Collateral Agent
party thereto, for the benefit of such Collateral Agent and the Holders, legal,
valid and enforceable security interests in all right, title and interest of the
Issuer party to such Collateral Document in the Collateral purportedly in pledge
thereunder, which security interests constitute and shall continue to constitute
fully perfected and continuing first priority Liens on and security interests in
all right, title and interest of such Issuer in such Collateral. Except for SCA
A Shares, which may only be owned by Mexican investors (unless otherwise
approved by the Foreign Investment Commission and the Ministry of Finance), all
of the Collateral may be owned by foreign investors (including without
limitation the U.S. Collateral Agent and the Holders) pursuant to the estatutos
sociales and other constitutional 


                                       42
<PAGE>

documents of SCA, Seminis, DNAP and Empaques, as applicable, the Mexican Foreign
Investment Law, the Mexican Insurance Law and other applicable laws, subject to
(i) the approval of the Ministry of Finance, if the SCA Shares to be acquired by
a single foreign or Mexican investor upon foreclosure under the Mexican Trust
Agreement amount to 10% or more of the capital stock of SCA, (ii) the absence of
objection of the Federal Competition Commission, if the amount of the
transaction arising from the foreclosure exceeds the threshold amount specified
under applicable law or such transaction otherwise raises competition issues,
and (iii) the approval of the Ministry of Finance and of the Foreign Investment
Commission, if upon foreclosure under the Mexican Trust Agreement non-Mexican
investors are to acquire control of SCA.

      SECTION 4.18. Year 2000 Compliance. Such Issuer has (i) initiated a review
and assessment of all areas within the business and operations of such Issuer
and its Subsidiaries (including those areas affected by suppliers and vendors)
that could be adversely affected by the "Year 2000 Problem" (that is, the risk
that computer applications used by such Issuer or its Subsidiaries (or their
respective suppliers and vendors) may be unable to recognize and perform
properly date-sensitive functions involving certain dates prior to and any date
after December 31, 1999), (ii) developed a plan and timeline for addressing the
Year 2000 Problem on a timely basis and (iii) to date, implemented such plan in
accordance with such timetable. Such Issuer reasonably believes that all
computer applications (including those of suppliers and vendors) that are
material to the business or operations of such Issuer or its Subsidiaries will
on a timely basis be able to perform properly date-sensitive functions for all
dates before and from and after January 1, 2000, except to the extent that a
failure to do so could not reasonably be expected to have a Material Adverse
Effect on such Issuer.

<PAGE>

aggregate reasonably be expected to have a Material Adverse Effect on such
Issuer.

dispose of any assets, tangible or intangible, to, or participate in, or effect,
any transaction with, any Affiliate except, in any case, on an arms-length basis
on terms at least as favorable to such Issuer or such Subsidiary as could have
been obtained from a third party who was not an Affiliate; provided that,
subject to Section 5.13, the foregoing provisions of this Section shall not
prohibit any such Person from declaring or paying any lawful dividend or other
payment ratably in respect of all of its capital stock of the relevant class so
long as, after giving effect thereto, no Default shall have occurred and be
continuing.

      SECTION 5.15. Use of Proceeds. The proceeds of the Issuance of the Tranche
A Notes and the Issuance of the Tranche B Notes will be used by Savia solely to
repay the Assumed Debt and other fees and expenses in connection with the
Restructuring and for general corporate purposes, including working capital. The
proceeds of the Issuance of the Tranche C Notes will be used by DNAP solely to
repay existing Debt of DNAP and its Subsidiaries in an aggregate principal
amount not less than $85,000,000 (less up to $30,000,000 of Debt permitted to
remain outstanding after the Closing Date pursuant to clause (b)(ii) of Section
5.10) and for general corporate purposes, including working capital. None of
such proceeds referred to above will be used, directly or indirectly, for the
purpose, whether immediate, incidental or ultimate, of buying or carrying any
"margin stock" within the meaning of Regulation U.

      SECTION 5.16. Intellectual Property Licenses. Savia shall at all times
afford Seminis, DNAP and their respective Subsidiaries the right of access to,
and to have all of the material benefits of technology sharing agreements with
Monsanto Co. and its affiliates, to the extent permitted under the terms of such
agreements and shall use its best efforts to cause such right of access and
benefits 


                                       51
<PAGE>

to continue, when and to the extent relevant in connection with any foreclosure
under the Collateral Documents, notwithstanding Seminis, DNAP or such Subsidiary
shall no longer be an "affiliate" or otherwise has any affiliation with Savia or
its Subsidiaries that may, on the date hereof, be a condition to such access or
benefits.

      SECTION 5.17. Certain Matters Relating to Collateral and Interest Reserve
Account.

      (a) Promptly after receiving instructions from the Required Holders at any
time during the continuance of an Event of Default, the Administrative Agent
shall direct the Collateral Agents that all Reserve Stock shall thereafter be
subject to the Lien created by the U.S. Pledge and Interest Reserve Agreement
and the Mexican Collateral Reserve Trust Agreement, respectively.

      (b) On the following dates during any Share Collateral Reduction Period,
the U.S. Collateral Agent, the Administrative Agent and Savia shall act as
follows:

            (i) On the first day of the Share Collateral Reduction Period (if
      any), the U.S. Collateral Agent shall advise the Administrative Agent of
      the largest number of SCA Shares, DNAP Shares and Empaques Shares (in that
      order) as may be released such that, after giving effect to such release,
      the Total Collateral Value (including all Seminis Shares, which shall not
      be subject to any release) is at least 300% of the aggregate outstanding
      principal amount of the Notes at such time. Upon receipt of such notice,
      but only if the Administrative Agent has not received any notice of the
      occurrence and continuance at such time of any Default, the Administrative
      Agent shall direct the Collateral Agents to release such shares as may be
      specified in such notice.

            (ii) On the last Domestic Business Day of any week, if the U.S.
      Collateral Agent determines that the Total Collateral Value is 280% or
      less of the aggregate outstanding principal amount of the Notes at such
      time, Savia will pledge, deposit or otherwise transfer such additional
      Eligible Collateral pursuant to the Collateral Documents such that,
      immediately after giving effect to such pledge and deposit, the Total
      Collateral Value shall be at least 300% of the aggregate outstanding
      principal amount of the Notes at such time.

            (iii) On the last Domestic Business Day of any week, the U.S.
      Collateral Agent shall notify the Administrative Agent if the Total
      Collateral Value is 320% or more of the aggregate outstanding principal
      amount of the Notes at such time. Upon receipt of any such notice, but
      only if Share Collateral other than Seminis Shares is then held under the


                                       52
<PAGE>

      Collateral Documents and the Administrative Agent has not received any
      notice of the occurrence and continuance at such time of any Default, the
      Administrative Agent will instruct the relevant Collateral Agent to cause
      the Mexican Trustee and the U.S. Collateral Agent to release from
      Collateral the maximum number of SCA Shares, DNAP Shares and Empaques
      Shares (in that order) such that, after giving effect to such release, the
      Total Collateral Value (including all Seminis Shares then held as
      Collateral, which shall not be subject to any release) is at least 300% of
      the aggregate outstanding principal amount of the Notes at such time.

            (iv) On the first day of the Share Collateral Reduction Period (if
      any), the Administrative Agent shall instruct the Mexican Trustee to
      provide to the U.S. Collateral Agent all information that the U.S.
      Collateral Trustee may reasonably request from time to time during the
      Share Collateral Reduction Period in order to determine Total Collateral
      Value as of any date during such period, in accordance with the terms of
      this section 5.17(b).

      (c) Any deposit, transfer or release required pursuant to this Section
5.17 shall be made not later than the second Domestic Business Day after the
date on which the relevant notice is given by the Collateral Agent. In the case
of any pledge, deposit or transfer of additional Eligible Collateral so
required, Savia shall first, pledge, deposit or otherwise transfer any Empaques
Shares then available to be pledged, deposited or transferred pursuant to the
Collateral Documents, second, pledge, deposit or transfer any DNAP Shares then
available to be pledged, deposited or otherwise transferred pursuant to the
Collateral Documents, and third, pledge and deposit any SCA Shares then
available to be pledged and deposited pursuant to the Collateral Documents, all
as may be required to satisfy the foregoing requirement; and fourth, pledge and
deposit Unencumbered Cash with the U.S. Collateral Agent pursuant to a Cash
Collateral Agreement in form and substance reasonably satisfactory to the U.S.
Collateral Agent. SCA Shares, Empaques Shares and DNAP Shares shall be deemed to
be "available" to be pledged, deposited or transferred pursuant to the
Collateral Documents at any time if such shares are owned by Savia and not
required, by the terms of any other document governing the obligations of Savia,
to be held subject to a Lien in favor of another Person permitted pursuant to
the terms of this Agreement, and the chief accounting officer or chief financial
officer of Savia shall provide to the Administrative Agent, upon delivery of any
Eligible Collateral a certificate setting forth in reasonable detail the
Eligible Collateral owned by Savia and not pledged, deposited or transferred
hereunder, and not "available" (as so defined) to be so pledged and deposited.
If Unencumbered Cash shall be deposited as additional Eligible Collateral, the
relevant Issuers shall enter into the Cash Collateral Agreement and comply with
Section 5.17(a) with respect thereto.


                                       53

      (d) On the first day of each Interest Period, the Administrative Agent
shall determine the amount of interest expense to be paid on the Notes during
the next twelve months (on any day, for the next such period, the "Interest
Reserve Amount") assuming that (i) the interest rate determined with respect to
each Tranche of Notes on such day will continue to apply in all respects to such
Tranche of Notes for the next twelve months in all respects and (ii) any
scheduled payments of principal on the Notes will be made on the dates so
provided (including without limitation any payments of Notes of any Tranche upon
maturity, but not including any optional or unscheduled mandatory payments). The
Administrative Agent shall promptly inform the Company and the U.S. Collateral
Agent of the Interest Reserve Amount as determined on such date, and the Company
shall forthwith deposit into the Interest Reserve Account (as defined in the
U.S. Pledge and Interest Reserve Agreement), or, if the Administrative Agent has
not received any notice of the occurrence and continuance at such time of any
Default, the Administrative Agent shall instruct the U.S. Collateral Agent to
release to the Company, as appropriate, an amount of cash such that after such
deposit or withdrawal, as relevant, the amount of cash and Investments in the
Interest Reserve Account is equal to the Interest Reserve Amount.

      SECTION 5.18. Further Assurances. (a) Such Issuer will, at its sole cost
and expense, do, execute, acknowledge and deliver all such further acts, deeds,
conveyances, assignments, notices of pledges, liens, statements, notices,
assignment and transfers as the Administrative Agent or either Collateral Agent
shall from time to time request, which may be necessary in the reasonable
judgment of the Administrative Agent or the relevant Collateral Agent, as the
case may be, from time to time to assure, perfect, convey, assign and transfer
to the relevant Collateral Agent the property and rights conveyed or assigned
pursuant to the Collateral Documents, or which may facilitate the performance of
the terms of the Collateral Documents, or the filing, registering or recording
of the Collateral Documents (including without limitation any acknowledgment of
the Mexican Trust Agreement by the Mexican Foreign Investment Registry).

      (b) All costs and expenses in connection with the grant of any security
interests, the calculation of any Collateral Value or the pledge and deposit of
any additional Eligible Collateral under the Collateral Documents (or other
obligations under Sections 5.17 and 5.18), including without limitation
reasonable legal fees and other reasonable costs and expenses in connection with
the granting, perfecting and maintenance of any security interests, the
calculation of any Collateral Value or the pledge and deposit of any additional
Eligible Collateral under the Collateral Documents, or the preparation,
execution, delivery, recordation or filing of documents and any other acts as
the Administrative Agent, the Collateral Agent or either Collateral Agent may
reasonably request in 


                                       54
<PAGE>

connection with the grant of such security interests, calculation of such
Collateral Value or pledge and deposit of such additional Eligible Collateral,
shall be paid by Savia promptly upon demand.

      (c) Neither Issuer will, or will permit any of its Subsidiaries to, enter
into or become subject to any agreement that restricts or impairs (i) the
ability of such Issuer to comply with the provisions of this Agreement or (ii)
the ability of such Issuer or such Subsidiary to consummate the Reorganization
or any financing contemplated in connection therewith.

required to take any action with respect to any Default, except as expressly
provided in Article 6.

Agent, acting in its capacity as Agent, to expend or risk its own funds or
otherwise to incur any liability, financial or otherwise, in the performance of
any of its duties thereunder, or in the exercise of any of its rights or powers
if it shall have reasonable grounds for believing that repayment of such funds
or indemnity satisfactory to it against such risk or liability is not assured to
it.

      (d) Each Agent may conclusively rely and shall be fully protected in
acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval or other
paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties.

      (e) Whenever in the administration of the provisions of the Financing
Documents any Agent shall deem it necessary or desirable that a matter be
provided or established prior to taking or suffering any action to be taken
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of gross negligence or bad faith on
the part of such Agent, be deemed to be conclusively proved and established by a
certificate signed by the officers of the relevant Person or Persons, as the
case may be, and delivered to such Agent and such certificate or certificates,
in the absence of gross negligence or bad faith on the part of such Agent, shall
be full warrant to such Agent for any action taken, suffered or omitted by it
under the provisions of the Financing Documents upon the faith thereof.

be responsible for any willful misconduct or gross negligence on the part of any
agent, attorney, custodian or nominee so appointed.

converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Agent shall be a
party, or any Person succeeding to the business of such Agent shall be the
successor of such Agent hereunder without the execution or filing of any paper
with any party hereto or any further act on the part of any of the parties
hereto except where an instrument of transfer or assignment is required by law
to effect such succession, anything herein to the contrary notwithstanding.

that it shall accept delivery of any notice, information, instruction or other
communication delivered pursuant to the terms of this Agreement for and on
behalf of the Holders and agrees that it shall promptly deliver any such notice,

thereof. The Paying Agent shall not be liable for the content of any such
notice, information, instruction or communication nor for any delay caused by
the Paying Agent's failure to receive timely delivery of any such communication.

      SECTION 7.05. Consultation with Experts. Each Agent may consult with legal
counsel (who may be counsel for either Issuer), independent public accountants
and other experts selected by it and shall not be liable for any action taken or
omitted to be taken by it in good faith in accordance with the advice of such
counsel, accountants or experts.

      SECTION 7.06. Liability of Agents. (a) No Agent, its affiliates and their
respective directors, officers, agents and employees shall be liable for any
action taken or not taken by it in connection with the Financing Documents (i)
with the consent or at the request of the Required Holders (or such different
number of Holders as any provision hereof expressly requires for such consent or
request) or (ii) in the absence of its own gross negligence or willful
misconduct, the existence of which must be determined by the final judgment of a
court of competent jurisdiction, no longer subject to appeal or review. No
Agent, its affiliates and their respective directors, officers, agents and
employees shall be responsible for or have any duty to ascertain, inquire into
or verify (i) any statement, warranty or representation made in connection with
the Financing Documents or any issuance hereunder; (ii) the performance or
observance of any of the covenants or agreements of either Issuer; (iii) the
satisfaction of any condition specified in Article 3, except receipt of items
required to be delivered to the Administrative 


                                       61
<PAGE>

Agent; (iv) the validity, effectiveness or genuineness of the Financing
Documents or any other instrument or writing furnished in connection herewith;
or (v) the existence or sufficiency of any Collateral. No Agent shall incur any
liability by acting in reliance upon any notice, consent, certificate, statement
or other writing (which may be a bank wire, telex, facsimile or similar writing)
believed by it to be genuine or to be signed by the proper party or parties.
Without limiting the generality of the foregoing, the use of the term
"administrative agent" in this Agreement with reference to the Administrative
Agent is not intended to connote any fiduciary or other implied (or express)
obligations arising under agency doctrine of any applicable law. Instead, such
term is used merely as a matter of market custom and is intended to create or
reflect only an administrative relationship between independent contracting
parties.

      (b) Each of the Holders (for itself and any Person or entity claiming
through it) hereby releases, waives, discharges, exculpates and covenants not to
sue any Agent for any action taken or omitted under the Financing Documents
except to the extent caused by such Agent's gross negligence or willful
misconduct. Anything in the Financing Documents to the contrary notwithstanding,
in no event shall any Agent be liable for special, indirect or consequential
loss or damage of any kind whatsoever (including but not limited to lost
profits), even if such Agent has been advised of the likelihood of such loss or
damage and regardless of the form of action.

      SECTION 7.07. Indemnification. The Holders shall, ratably in proportion to
their Commitments, indemnify each Agent, its affiliates and their respective
directors, officers, agents and employees (to the extent not reimbursed by the
Issuers) against any cost, expense (including counsel fees and disbursements),
claim, demand, action, loss or liability (except such as result from such
indemnitees' gross negligence or willful misconduct) that such indemnitees may
suffer or incur in connection with the Financing Documents or any action taken
or omitted by such indemnitees hereunder. The obligations of the Holders under
this Section 7.07 to indemnify each Agent shall survive the satisfaction and
discharge of this Agreement or the earlier resignation or removal of any Agent.

      SECTION 7.08. Credit Decision. Each Holder acknowledges that it has,
independently and without reliance on any Agent or any other Holder, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Holder also
acknowledges that it will, independently and without reliance on any Agent or
any other Holder, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under the Financing Documents.

      SECTION 7.09. Successor Agents. Any Agent may resign at any time by giving
notice thereof to the Holders and the Issuers. Upon any such resignation, the
Required Holders shall have the right to appoint a successor Agent to such
Agent. If no such successor Agent shall have been so appointed by the Required
Holders, and shall have accepted such appointment, within 30 days after the
retiring Agent gives notice of resignation, then the retiring Agent may, on
behalf of the Holders, appoint a successor Agent, which shall be a commercial
bank organized or licensed under the laws of the United States or of any State
thereof (or, in the case of the Mexican Trustee, the laws of Mexico) and having
a combined capital and surplus of at least $100,000,000 (or, in the case of the
Mexican Trustee, $50,000,000). Upon the acceptance of its appointment as an
Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights and duties of the retiring
Agent, and the retiring Agent shall be discharged from its duties and
obligations hereunder. After any retiring Agent resigns as an Agent hereunder,
the provisions of this Article shall inure to its benefit as to actions taken or
omitted to be taken by it while it was such an Agent.

      SECTION 7.10. Agents' Fee. The Issuers shall pay to each Agent for its own
account and each Agent shall be entitled to, the fees and expenses agreed in
writing between the Issuers and such Agent, and will further pay or reimburse
such Agent upon its request for all reasonable expenses, disbursements and
advances incurred or made by such Agent in accordance with any of the provisions
hereof or any other document executed in connection herewith (including the
reasonable compensation and the reasonable expenses and disbursements of its
counsel and of all persons not regularly in its employ), including, with respect
to the Administrative Agent, an agency fee for its role as Administrative Agent
in an amount of $25,000 per annum payable quarterly in arrears. The obligations
of the Issuers under this Section 7.10 to compensate each Agent and to pay or
reimburse each Agent for reasonable expenses, disbursements and advances shall
survive the satisfaction and discharge of this Agreement or the earlier
resignation or removal of such Agent.

                             CHANGE IN CIRCUMSTANCES

      SECTION 8.01. Basis for Determining Interest Rate Inadequate or Unfair. 
If on or prior to the first day of any Interest Period:

            (a) the Administrative Agent is advised by the Reference Banks that
      deposits in dollars (in the applicable amounts) are not being offered to


                                       63
<PAGE>

      the Reference Banks in the London interbank market for such Interest
      Period, or

            (b) Holders which are Banks having 50% or more of the aggregate
      principal amount of the affected Notes advise the Administrative Agent
      that LIBOR as determined by the Administrative Agent will not adequately
      and fairly reflect the cost to such Holders of funding their Notes for
      such Interest Period,

the Administrative Agent shall forthwith notify each Issuer and shall instruct
the Paying Agent promptly to give notice to the Holders, whereupon until the
Administrative Agent notifies each Issuer that the circumstances giving rise to
such suspension no longer exist, (i) the obligations of the Holders to have
Notes bear interest at the Euro-Dollar Rate shall be suspended and (ii) each
outstanding Note shall bear interest at the Alternative Rate from and after the
last day of the then current Interest Period applicable thereto.

      SECTION 8.02. Illegality. If, on or after the date of this Agreement, the
adoption of any applicable law, rule or regulation, or any change in any
applicable law, rule or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Holder which is a Bank (or its Euro-Dollar Lending Office) with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall make it unlawful or
impossible for any Holder which is a Bank (or its Euro-Dollar Lending Office) to
make, maintain or fund Notes at the Euro-Dollar Rate and such Holder shall so
notify the Administrative Agent and the Paying Agent, the Administrative Agent
shall forthwith give notice thereof to each Issuer and shall instruct the Paying
Agent promptly to notify the other Holders, whereupon until such Holder notifies
each Issuer, the Administrative Agent and the Paying Agent that the
circumstances giving rise to such suspension no longer exist, the obligation of
such Holder to make or maintain Notes at the Euro-Dollar Rate shall be
suspended. Before giving any notice to the Administrative Agent and the Paying
Agent pursuant to this Section, such Holder shall designate a different
Euro-Dollar Lending Office if such designation will avoid the need for giving
such notice and will not, in the judgment of such Holder, be otherwise
disadvantageous to such Holder. If such notice is given, each Note of such
Holder then outstanding shall begin to bear interest at the Alternative Rate
either (a) on the last day of the then current Interest Period applicable to
such Note if such Holder may lawfully continue to maintain and fund such Note to
such day or (b) immediately if such Holder shall determine that it may not
lawfully continue to maintain and fund such Note to such day.

      SECTION 8.03. Increased Cost and Reduced Return. (a) If on or after the
date hereof, the adoption of any applicable law, rule or regulation, or any
change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Holder which is a Bank (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall impose, modify or
deem applicable any reserve (including, without limitation, any such requirement
imposed by the Board of Governors of the Federal Reserve System), special
deposit, insurance assessment or similar requirement against assets of, deposits
with or for the account of, or credit extended by, any Holder which is a Bank
(or its Applicable Lending Office) or shall impose on any Holder which is a Bank
(or its Applicable Lending Office) or the London interbank market any other
condition affecting its Notes or its obligation to make or maintain Notes at the
Euro-Dollar Rate and the result of any of the foregoing is to increase the cost
to such Holder (or its Applicable Lending Office) of making or maintaining any
Note at the Euro-Dollar Rate, or to reduce the amount of any sum received or
receivable by such Holder (or its Applicable Lending Office) under this
Agreement or under its Note with respect thereto, by an amount deemed by such
Holder to be material, then, within 15 days after demand by such Holder (with a
copy to the Administrative Agent and the Paying Agent), each Issuer shall pay to
such Holder such additional amount or amounts as will compensate such Holder for
such increased cost or reduction.

      (b) If any Holder which is a Bank shall have determined that, after the
date hereof, the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change in any such law, rule or regulation, or any
change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on capital of such Holder (or its Parent) as a consequence of such Holder's
obligations hereunder to a level below that which such Holder (or its Parent)
could have achieved but for such adoption, change, request or directive (taking
into consideration its policies with respect to capital adequacy) by an amount
deemed by such Holder to be material, then from time to time, within 15 days
after demand by such Holder (with a copy to the Administrative Agent and the
Paying Agent), the relevant Issuer shall pay to such Holder such additional
amount or amounts as will compensate such Holder (or its Parent) for such
reduction.


                                       65
<PAGE>

      (c) Each Holder will promptly notify each Issuer and the Administrative
Agent of any event of which it has knowledge, occurring after the date hereof,
which will entitle such Holder to compensation pursuant to this Section and will
designate a different Lending Office if such designation will avoid the need
for, or reduce the amount of, such compensation and will not, in the judgment of
such Holder, be otherwise disadvantageous to such Holder. A certificate of any
Holder claiming compensation under this Section and setting forth the additional
amount or amounts to be paid to it hereunder shall be conclusive in the absence
of manifest error. In determining such amount, such Holder may use any
reasonable averaging and attribution methods.

      SECTION 8.04. Mexican Taxes. All payments of principal, premium and
interest in respect of each Note or the Guarantee shall be made free and clear
of, and without withholding or deduction for, any taxes, duties, assessments or
governmental charges or penalties or interest related thereto of whatever nature
imposed, levied, collected, withheld or assessed by or within Mexico or any
political subdivision or taxing authority thereof or therein ("Mexican Taxes"),
unless such withholding or deduction is required by law or by regulation. In the
event that any such withholding or deduction in respect of principal, premium or
interest is so required, the Issuers or the Guarantor, as the case may be, shall
pay such additional amounts ("Additional Amounts") as will result in receipt by
each holder of any Note of such amounts as would have been received by such
holder with respect to such Note or Guarantee, as applicable, had no such
withholding or deduction been required, except that no Additional Amounts shall
be payable for or on account of:

            (1) any tax, duty, assessment or other governmental charge imposed
      by reason of

                  (A) the existence of any present or former connection between
            such holder or the beneficial owner of such Note and Mexico (or any
            political subdivision or taxing authority thereof or therein) other
            than merely holding such Note or the receipt of payments, or
            enforcement of rights, under the Guarantee or the Notes, including,
            without limitation, such holder or the beneficial owner of such Note
            being or having been a national, domiciliary or resident thereof or
            being or having been present or engaged in a trade or business
            therein or having had a permanent establishment therein; or

                  (B) the presentation of such Note (where presentation is
            required) more than 30 days after the date on which the payment in
            respect of such Note became due and payable or provided for,


                                       66
<PAGE>

            whichever is later, except to the extent that such holder would have
            been entitled to such Additional Amounts if it had presented such
            Note for payment on the last day of such period of 30 days;

            (2) any estate, inheritance, gift, sale, transfer, personal property
      or similar tax, assessment or other governmental charge;

            (3) (A) any Mexican Taxes imposed at a rate in excess of the 10%
      uniformly applicable in respect of payments made by the Issuers or the
      Guarantor to all holders or beneficial owners as a result of the failure
      of the holder or beneficial owner of such Note to comply with any
      certification, identification, information, documentation or other
      reporting requirement if (i) such compliance is required by law,
      regulation or administrative practice as a precondition to exemption from,
      or reduction in the rate of, deduction or withholding of Mexican Taxes,
      (ii) at least 60 days prior to the first interest payment date with
      respect to which the Issuers or the Guarantor shall apply this paragraph
      (3)(A), the Issuers or the Guarantor shall have notified the holders of
      the Notes, in writing, that such holders or beneficial owners of the Notes
      will be required to comply with such requirement and (iii) the
      notification described in clause (ii) shall have been furnished to holders
      of the Notes through DTC (or its custodian, if applicable) or by other
      comparable means in such a manner as to have reasonably afforded such
      holders or beneficial owners a reasonable time and opportunity to so
      comply;

                  (B) any Mexican Taxes imposed at a rate in excess of the 15%
            uniformly applicable in respect of payments made by the Issuers or
            the Guarantor to all holders or beneficial owners eligible for the
            benefits of a treaty for the avoidance of double taxation to which
            Mexico is a party and which is in effect, but only to the extent
            that (i) such holder or beneficial owner has failed to provide on a
            timely basis, at the reasonable request of the Issuers or the
            Guarantor (subject to the conditions set forth below), information,
            documentation or other evidence (not described in paragraph (3)(A)
            above) concerning whether 


                                       67
<PAGE>

            such holder or beneficial owner is eligible for benefits under a
            treaty for the avoidance of double taxation to which Mexico is a
            party and which is in effect if necessary to determine the
            appropriate rate of deduction or withholding of Mexican Taxes under
            such treaty or under any law, (ii) at least 60 days prior to the
            first payment date with respect to which the Issuers or the
            Guarantor shall make such reasonable request, the Issuers or the
            Guarantor shall have notified the holders of the Notes, in writing,
            that such holders or beneficial owners of the Notes will be required
            to provide such information, documentation or other evidence and
            (iii) the notification described in clause (ii) shall have been
            furnished to holders of the Notes through DTC (or its custodian, if
            applicable) or by other comparable means in such a manner as to have
            reasonably afforded such holders or beneficial owners a reasonable
            time and opportunity to provide the information, documentation or
            other evidence required by this paragraph; or

      (4) any combination of items (1), (2) or (3).

      For purposes of the provisions described in paragraph (3), the term
"holder" shall mean the direct nominee of such beneficial owner, which holds
such beneficial owner's interest in the Notes. Notwithstanding the foregoing,
the limitations on the Issuers and Guarantor's obligation to pay Additional
Amounts set forth in paragraph (3) above shall not apply if (a) the provision of
information, documentation or other evidence described in such paragraph (3)
would be materially more onerous, in form, in procedure or in the substance of
information disclosed, to a holder or beneficial owner of a Note (taking into
account any relevant differences between U.S. and Mexican law, regulation or
administrative practice) than comparable information or other reporting
requirements imposed 


                                       68
<PAGE>

under U.S. tax law, regulation and administrative practice (such as IRS Forms
1001, W-8 and W-9) or (b) Rule 3.32.9 issued by the Ministry of Finance on March
3, 1999 or a substantially similar successor of such rule is in effect, unless
the provision of the information, documentation or other evidence described in
paragraph (3) is expressly required by statute, regulation, rule or
administrative practice in order to apply Rule 3.32.9 (or a substantially
similar successor of such rule), the Issuers or the Guarantor cannot obtain such
information, documentation or other evidence on its own through reasonable
diligence and the Issuers or the Guarantor otherwise would meet the requirements
for application of Rule 3.32.9 (or such successor of such rule). In addition,
such paragraph (3) shall not be construed to require that a non-Mexican pension
or retirement fund or a non-Mexican financial institution or any other holder
register with the Ministry of Finance and Public Credit for the purpose of
establishing eligibility for an exemption from or reduction of Mexican
withholding tax. Furthermore, compliance with any such requirements under
paragraph (3)(A) or requests under paragraph (3)(B) shall not require the
disclosure to the Issuers, the Guarantor, the Administrative Agent and the
Paying Agent or any governmental authority of the nationality, residence or
identity of the beneficial owner of a Note that is not eligible for any
exemption from withholding or deduction of all or any part of such Mexican Taxes
(other than such compliance that can be satisfied by a custodian, nominee or
other agent of such beneficial owner certifying to the effect that such
beneficial owner is not eligible for any exemption from withholding or deduction
of all or any part of such Mexican Taxes, provided that payment by such
custodian, nominee or agent to such beneficial owner is not otherwise subject to
any such requirement).

      Whenever there is mentioned in any context, the payment of principal,
premium or interest in respect of any Note or the net proceeds received on the
sale or exchange of any Note, such mention shall be deemed to include the
payment of Additional Amounts provided for herein to the extent that, in such
context, Additional Amounts are, were or would be payable in respect thereof
pursuant to this Agreement.

      The Issuers or the Guarantor, as the case may be, will provide to the
Administrative Agent and the Paying Agent documentation evidencing payment of
withholding taxes within 30 days after payment thereof. Copies of such
documentation shall be provided to holders requesting them.

      The Issuers or the Guarantor, as the case may be, will pay any present or
future stamp, issue, registration or documentary taxes, or any other excise or
property taxes, charges or similar levies which arise in any jurisdiction from
the execution, delivery or registration of the Notes or the Guarantee, except
for any such taxes, charges or similar levies imposed by any jurisdiction
outside of 


                                       69
<PAGE>

Mexico (other than those resulting from, or required to be paid in connection
with, the enforcement of the Notes or the Guarantee following the occurrence of
any Event of Default with respect to the Notes). Notwithstanding the foregoing,
no service charge will be made for any registration of transfer or exchange of
Notes, but the Issuer may require payment of a sum sufficient to cover any
transfer tax or other similar governmental charge payable in connection
therewith. For the avoidance of doubt, Issuers' obligations in respect of the
payment of additional amounts shall in no event be reduced or offset as a result
of any tax or other benefits accruing to Holders relating to the payment of
withholding taxes.

      SECTION 8.05. U.S. Taxes. All payments of principal, premium and interest
in respect of each Tranche C Note and the Guarantee shall be made free and clear
of, and without withholding or deduction for, any taxes, duties, assessments or
governmental charges or penalties or interest related thereto of whatever nature
imposed, levied, collected, withheld or assessed by or within the United States
or any political subdivision or taxing authority thereof or therein ("U.S.
Taxes"), unless such withholding or deduction is required by law or by
regulation. In the event that any such withholding or deduction in respect of
principal, premium or interest is so required, DNAP or the Guarantor, as the
case may be, shall pay such Additional Amounts as will result in receipt by each
holder of any Tranche C Note of such amounts as would have been received by such
holder with respect to such Tranche C Note or Guarantee, as applicable, had no
such withholding or deduction been required, except that no Additional Amounts
shall be payable for or on account of:

            (a) any tax, duty, assessment or other governmental charge imposed
      by reason of

                  (i) the existence of any present or former connection between
            such holder or the beneficial owner of such Tranche C Note and the
            United States (or any political subdivision or taxing authority
            thereof or therein) other than merely holding such Tranche C Note or
            the receipt of payments, or enforcement of rights, under the
            Guarantee or the Tranche C Notes, including, without limitation,
            such holder or the beneficial owner of such Tranche C Note being or
            having been a national, domiciliary or resident thereof or being or
            having been present or engaged in a trade or business therein or
            having had a permanent establishment therein; or

                  (ii) the presentation of such Tranche C Note (where
            presentation is required) more than 30 days after the date on which
            the payment in respect of such Tranche C Note became due and 


                                       70
<PAGE>

            payable or provided for, whichever is later, except to the extent
            that such holder would have been entitled to such Additional Amounts
            if it had presented such Tranche C Note for payment on the last day
            of such period of 30 days;

            (b) any estate, inheritance, gift, sale, transfer, personal property
      or similar tax, assessment or other governmental charge or any tax imposed
      other than by withholding;

            (c) any withholding taxes imposed at a rate in excess of 3.0% of
      such taxable payments unless such excess is the result of a change in law
      that becomes effective after the Closing Date; and

            (d) any taxes imposed by reason of the holder's failure (or, if the
      holder is not the beneficial owner, the beneficial owner's failure) to
      provide upon reasonable request addressed to such holder or beneficial
      owner either (i) a duly completed Form W-8 (or successor form) and
      certification that it is not (A) a bank within the meaning of Internal
      Revenue Code section 881(c), (B) a 10% shareholder of DNAP within the
      meaning of Internal Revenue Code section 871(h)(3)(B) nor (C) a controlled
      foreign corporation related to DNAP within the meaning of Internal Revenue
      Code section 864(d)(4) or (ii) a duly completed Form 4224 or Form 1001 (or
      successor forms) entitling the holder to a complete exemption from, or
      reduction in, the rate of withholding tax.

      SECTION 8.06. Alternative Rate Substituted for Euro-Dollar Rate. If (i) 
the obligation of any Holder to make or maintain Notes at the Euro-Dollar 
Rate has been suspended pursuant to Section 8.02 or (ii) any Holder has 
demanded compensation under Section 8.03, 8.04 or 8.05 with respect to its 
Notes with respect to the Euro-Dollar Rate and the relevant Issuer shall, by 
at least five Euro-Dollar Business Days' prior notice to such Holder through 
the Administrative Agent, have elected that the provisions of this Section 
shall apply to such Holder, then, unless and until such Holder notifies such 
Issuer that the circumstances giving rise to such suspension or demand for 
compensation no longer exist, all Notes of such Holder shall bear interest at 
the Alternative Rate (on which interest and principal shall be payable 
contemporaneously with the related payments of interest to the other 
Holders). If such Holder notifies an Issuer that the circumstances giving 
rise to such notice no longer apply, each applicable Note shall again bear 
interest at the Euro-Dollar Rate from and after the first day of the next 
succeeding Interest Period applicable to such Note.

      SECTION 8.07. Substitution of Holder. If (a) the obligation of any Holder
to purchase or maintain Notes bearing interest at the Euro-Dollar Rate has been


                                       71
<PAGE>

suspended pursuant to Section 8.02 or (b) any Holder has demanded compensation
under Sections 8.03, 8.04 or 8.05, the Issuers shall have the right, with the
assistance of the Administrative Agent, to seek a mutually satisfactory
substitute bank or banks (which may be one or more of the Holders) to purchase
the affected Notes and assume the Commitments of such Holder.

      SECTION 9.01. The Guaranty. The Guarantor hereby unconditionally 
guarantees the full and punctual payment (whether at stated maturity, upon 
acceleration or otherwise) of the principal of and interest on each Tranche C 
Note issued by DNAP pursuant to this Agreement, and the full and punctual 
payment of all other amounts payable by DNAP under this Agreement. Upon 
failure by DNAP to pay punctually any such amount, the Guarantor shall 
forthwith on demand pay the amount not so paid at the place and in the manner 
specified in this Agreement.

      SECTION 9.02. Guaranty Unconditional. The obligations of the Guarantor
hereunder shall be unconditional and absolute and, without limiting the
generality of the foregoing, shall not be released, discharged or otherwise
affected by:

            (a) any extension, renewal, settlement, compromise, waiver or
      release in respect of any obligation of DNAP under this Agreement or any
      Tranche C Note, by operation of law or otherwise;

            (b) any modification or amendment of or supplement to this Agreement
      or any Note;

            (c) any release, impairment, non-perfection or invalidity of any
      direct or indirect security for any obligation of Company under this
      Agreement or any Tranche C Note;

            (d) any change in the corporate existence, structure or ownership of
      DNAP, or any insolvency, bankruptcy, reorganization or other similar
      proceeding affecting DNAP or its assets or any resulting release or
      discharge of any obligation of DNAP contained in this Agreement or any
      Tranche C Note;

            (e) the existence of any claim, set-off or other rights which the
      Guarantor may have at any time against DNAP, any Agent, any Holder or 


                                       72
<PAGE>

      any other Person, whether in connection with this Agreement or any
      unrelated transactions; provided that nothing herein shall prevent the
      assertion of any such claim by separate suit or compulsory counterclaim;

            (f) any invalidity or unenforceability relating to or against DNAP
      for any reason of this Agreement or any Tranche C Note, or any provision
      of applicable law or regulation purporting to prohibit the payment by DNAP
      of the principal of or interest on any Tranche C Note or any other amount
      payable by DNAP under this Agreement; or

            (g) any other act or omission to act or delay of any kind by DNAP,
      any Agent, any Holder or any other Person or any other circumstance
      whatsoever which might, but for the provisions of this paragraph,
      constitute a legal or equitable discharge of or defense to the Guarantor's
      obligations hereunder.

      SECTION 9.03. Discharge Only Upon Payment In Full; Reinstatement In 
Certain Circumstances. The Guarantor's obligations hereunder shall remain in 
full force and effect until the principal of and interest on the Tranche C 
Notes and all other amounts payable by DNAP under this Agreement shall have 
been paid in full. If at any time any payment of the principal of or interest 
on any Tranche C Note or any other amount payable by DNAP under this 
Agreement is rescinded or must be otherwise restored or returned upon the 
insolvency, bankruptcy or reorganization of DNAP or otherwise, the 
Guarantor's obligations hereunder with respect to such payment shall be 
reinstated as though such payment had been due but not made at such time.

      SECTION 9.04. Waiver by the Guarantor. The Guarantor irrevocably waives:

            (a) acceptance hereof, presentment, demand, protest and any notice
      not provided for herein, as well as any requirement that at any time any
      action be taken by any Person against DNAP or any other Person;

            (b) any right to which it may be entitled in connection with any
      obligation of any Lender to sue and/or complete an action against DNAP
      prior to a claim being made against the Guarantor hereunder; and

            (c) any right to which it may be entitled to have the assets of DNAP
      first be used and/or applied in full as payment of DNAP's or the
      Guarantor's obligations hereunder prior to any amounts being claimed from
      or paid by the Guarantor hereunder.


                                       73
<PAGE>

      SECTION 9.05. Subrogation. Upon making full payment with respect to any
obligation of DNAP hereunder, the Guarantor shall be subrogated to the rights of
the payee against DNAP with respect to such obligation; provided that the
Guarantor shall not enforce any payment by way of subrogation so long as any
amount payable by DNAP hereunder remains unpaid.

      SECTION 9.06. Stay of Acceleration. If acceleration of the time for 
payment of any amount payable by DNAP under this Agreement or the Tranche C 
Notes is stayed upon the insolvency, bankruptcy or reorganization of DNAP, 
all such amounts otherwise subject to acceleration under the terms of this 
Agreement shall nonetheless be payable by the Guarantor hereunder forthwith 
on demand by the Administrative Agent made at the request of the Required 
Holders.

                                   ARTICLE 10

                                  MISCELLANEOUS

      SECTION 10.01. Notices. All notices, requests and other communications 
to any party hereunder shall be in writing (including bank wire, telex, 
facsimile or similar writing) and shall be given to such party: (i) in the 
case of either Issuer, the Administrative Agent, the Paying Agent or either 
Collateral Agent, at its address or facsimile number set forth on the 
signature pages hereof, (ii) in the case of any Holder, by notice to the 
Paying Agent or at such Holder's address or facsimile number set forth in its 
Administrative Questionnaire or (iii) in the case of any party, at such other 
address or facsimile number as such party may hereafter specify for the 
purpose by notice to the Administrative Agent, the Paying Agent and the 
Issuers. Each such notice, request or other communication shall be effective 
(i) if given by facsimile, when transmitted to the facsimile number referred 
to in this Section and confirmation of receipt is received or (ii) if given 
by any other means, when delivered at the address referred to in this 
Section; provided that notices to the Administrative Agent under Article 2 or 
Article 8 shall not be effective until received.

      SECTION 10.02. No Waivers. No failure or delay by any Agent or any Holder
in exercising any right, power or privilege hereunder or under any other
Financing Document shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.


                                       74
<PAGE>

      SECTION 10.03. Expenses; Indemnification. (a) The Issuers shall pay (i) 
all out-of-pocket expenses of the Agents and Arrangers, including reasonable 
fees and disbursements of special counsel for the Agents and Arrangers, in 
connection with the preparation and administration of the Financing 
Documents, any waiver or consent thereunder or any amendment thereof or any 
Default or alleged Default hereunder, (ii) all expenses referred to in the 
Financing Documents and (iii) if an Event of Default occurs, all 
out-of-pocket expenses incurred by each Agent and each Holder, including 
(without duplication) the reasonable fees and disbursements of outside 
counsel and the allocated cost of inside counsel, in connection with such 
Event of Default and collection, bankruptcy, insolvency and other enforcement 
proceedings resulting therefrom.

      (b) The Issuers agree to indemnify each Agent and each Holder, their
respective affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, settlement costs and the
reasonable fees and disbursements of counsel, which may be incurred by such
Indemnitee (i) in connection with any investigative, administrative or judicial
proceeding (whether or not such Indemnitee shall be designated a party thereto)
brought or threatened relating to or arising out of any Financing Document or
any actual or proposed use of the Commitments or the proceeds of Notes hereunder
(except with respect to matters expressly set forth in paragraph (c) below,
which shall be governed by the provisions of paragraph (c) and (ii) in the case
of the Agents, their respective affiliates and their respective directors,
officers, agents and employees only, as a result of such Agent's administration
of, and performance of its obligations under, the Financing Documents; provided
that no Indemnitee shall have the right to be indemnified hereunder for such
Indemnitee's own gross negligence or willful misconduct as determined by a court
of competent jurisdiction.

      (c) The Issuers agree to indemnify and hold harmless each Holder and each
person, if any, who controls any Holder within the meaning of either Section 15
of the Securities Act or Section 20 of the Exchange Act, from and against any
and all losses, claims, damages and liabilities (including without limitation
the legal fees and other expenses incurred in connection with any suit, action
or proceeding or any claim asserted) caused by any untrue statement or alleged
untrue statement of a material fact contained in the Offering Memorandum (and
any amendment or supplement thereto if the Issuers shall have furnished any
amendments or supplements thereto) or any preliminary offering memorandum, or
caused by 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, except insofar as such losses, claims, damages or liabilities are
caused by any untrue statement or omission or alleged untrue statement or
omission made 


                                       75
<PAGE>

in reliance upon and in conformity with information relating to any Holder
furnished to the Issuers in writing by such Holder through the Agents expressly
for use therein.

      (d) If the indemnification provided for in Section 10.03(c) is unavailable
to any Indemnitee or insufficient in respect of any losses, claims, damages or
liabilities referred to therein, then each Issuer under such paragraph, in lieu
of indemnifying such Indemnitee thereunder, shall contribute to the amount paid
or payable by such Indemnitee as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Issuers on the one hand and the Holders on the other
hand from the offering of the Notes 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 Issuers on the one hand and the Holders
on the other in connection with the statements or omissions that resulted in
such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations. The relative benefits received by the Issuers on the
one hand and the Holders on the other shall be deemed to be in the same
respective proportions as the net proceeds from the offering (before deducting
expenses) received by the Issuers and the total discounts and commissions
received by the Holders, in each case as set forth in the table on the cover of
the Offering Memorandum, bear to the aggregate offering price of the Notes. The
relative fault of the Issuers on the one hand and the Holders on the other 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 Issuer or by the Holders
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

      SECTION 10.04. Sharing of Set-offs. (a) Each Holder agrees, subject to
clause (b) below, that if it shall, by exercising any right of set-off or
counterclaim or otherwise, receive payment of a proportion of the aggregate
amount of principal and interest due with respect to any Note held by it which
is greater than the proportion received by any other Holder in respect of the
aggregate amount of principal and interest due with respect to any Note held by
such other Holder, the Holder receiving such proportionately greater payment
shall purchase such participations in the Notes held by the other Holders, and
such other adjustments shall be made, as may be required so that all such
payments of principal and interest with respect to the Notes held by the Holders
shall be shared by the Holders pro rata; provided that nothing in this Section
shall impair the right of any Holder to exercise any right of set-off or
counterclaim against all deposits (general or special, time or demand,
provisional or final at any time held it may have and to apply the amount
subject to such exercise to the payment of indebtedness of 


                                       76
<PAGE>

any Issuer other than its indebtedness hereunder. Each Issuer agrees, to the
fullest extent it may effectively do so under applicable law, that (i) any
Holder which is a Bank may exercise all rights of set-off or counterclaim with
respect to any obligation owed to either Issuer, whether or not matured or due
at the time of such exercise, with respect to principal of and interest on its
Notes and other amounts owing to such Holder hereunder, whether or not such
Holder shall have first made any demand hereunder and (ii) any holder of a
participation in a Note, whether or not acquired pursuant to the foregoing
arrangements, may exercise rights of set-off or counterclaim and other rights
with respect to such participation as fully as if such holder of a participation
were a direct creditor of such Issuer in the amount of such participation.

      (b) If at any time there shall occur and be continuing a Monetary Control
Condition, then one or more Holders (each, an "Accepting Holder") may agree to
receive payment of principal of and all accrued and unpaid interest on one or
more of its Notes in Pesos (each Note so paid, an "Affected Note"), and such
Accepting Holder (and each other Holder becoming an Additional Accepting Holder
as referred to below) shall not be required to purchase a participation from, or
make such other adjustments with, any other Holder in respect of the other Notes
of the same Tranche as the Affected Notes. Prior to accepting any such payment
as described above with respect to any prospective Affected Note, each Accepting
Holder shall provide reasonable notice to the Administrative Agent, the Paying
Agent and the Registrar (who shall promptly notify each other Holder thereof) of
such proposed payment in Pesos, setting forth the proposed terms thereof, and
each other Holder that elects, by notice delivered promptly to the Issuers,
Administrative Agent, Paying Agent and Registrar, to receive the same such
payment in Pesos with respect to one or more of its Notes (an "Additional
Accepting Holder") shall receive a payment with respect thereto pro rata to that
received by the initial Accepting Holder. Any such payment in Pesos pursuant to
this clause (b), including the calculation of the exchange rate with respect to
Dollars, shall be binding on any Holder agreeing to such payment and shall
constitute full and final payment with respect to the amounts of the Affected
Notes so paid. Nothing in this clause (b) shall be construed as a waiver by any
Holder, including any Holder not accepting payment in Pesos, of the obligations
of the Issuers to make payment in Dollars in accordance with Section 2.07 and
Section 10.11 of the Note Acquisition Agreement or any other remedies under the
same. As used herein, a "Monetary Control Condition" shall exist at any time if
at such time (i) an Event of Default under clause (t) of Section 6.01 has
occurred and is continuing as a result of the imposition of monetary or exchange
controls, the effect of which is to prevent or materially delay payment by the
Issuers of principal of and/or interest on any Notes in U.S. Dollars, but not to
prevent such payment in Pesos, and (ii) no Event of Default under any other
clause of Section 


                                       77
<PAGE>

6.01 is continuing at such time (except for any Event of Default occurring under
clause (a) thereof solely as a result thereof).

      SECTION 10.05. Amendments and Waivers; Certain Collateral Releases . Any
provision of this Agreement or the Notes may be amended or waived if, but only
if, such amendment or waiver is in writing and is signed by each Issuer and the
Required Holders (and, if the rights or duties of any Agent are affected
thereby, by such Agent); provided that no such amendment or waiver shall, unless
signed by all the Holders, (i) increase or decrease the Commitment of any Holder
(except for a ratable decrease in the Commitments of all Holders) or subject any
Holder to any additional obligation, (ii) reduce the principal of or rate of
interest on any Note, or any fees hereunder, (iii) postpone the date fixed for
any payment of principal of or interest on any Note, or any fees hereunder or
for any reduction or termination of any Commitment, (iv) release either Issuer
from its obligations hereunder, (v) change the currency of payment of any
obligation hereunder or under any other Financing Document, (vi) release the
Guarantor from its obligations or (vii) change the percentage of the Commitments
or of the aggregate unpaid principal amount of the Notes, or the number of
Holders, which shall be required for the Holders or any of them to take any
action under this Section or any other provision of this Agreement. Any
provision of any Collateral Document may be amended or waived if, but only if,
such amendment or waiver is in writing and is signed by the relevant parties
prescribed therein (including the Collateral Agents) with the consent of the
Required Holders; provided that no such amendment or waiver shall, unless signed
by all the Holders, release all or substantially all of the Collateral from the
Liens created by the Collateral Documents. The Collateral Agents may release
(and the Administrative Agent may instruct either Collateral Agent to release)
any Collateral sold or otherwise transferred in compliance with Section 5.09(b),
subject to the provisions thereof, and may execute and deliver, at Savia's sole
cost and expense, such documents to evidence such release as Savia may
reasonably request.

      SECTION 10.06. Successors and Assigns. (a) The provisions of this 
Agreement shall be binding upon and inure to the benefit of the parties 
hereto and their respective successors and assigns, except that neither 
Issuer may assign or otherwise transfer any of its rights under this 
Agreement without the prior written consent of all Holders.

      (b) Any Holder may at any time grant to one or more Holders or other
institutions (each a "Participant") participating interests in its Commitment or
any or all of its Notes. In the event of any such grant by a Holder of a
participating interest to a Participant, whether or not upon notice to the
Issuers and the Agent, such Holder shall remain responsible for the performance
of its obligations hereunder, and each Issuer and the Agent shall continue to
deal solely 


                                       78
<PAGE>

and directly with such Holder in connection with such Holder's rights and
obligations under this Agreement. Any agreement pursuant to which any Holder may
grant such a participating interest shall provide that such Holder shall retain
the sole right and responsibility to enforce the obligations of the relevant
Issuers hereunder including, without limitation, the right to approve any
amendment, modification or waiver of any provision of this Agreement; provided
that such participation agreement may provide that such Holder will not agree to
any modification, amendment or waiver of this Agreement relating to changes in
any fees hereunder, or the principal of or term of or rate of interest on any
Note, in any case that requires the consent of all Holders, without the consent
of the Participant. Each Issuer agrees that each Participant shall, to the
extent provided in its participation agreement, be entitled to the benefits of
Article 8 with respect to its participating interest. An assignment or other
transfer which is not permitted by subsection (c) or (d) below shall be given
effect for purposes of this Agreement only to the extent of a participating
interest granted in accordance with this subsection (b).

      (c) Any Holder may at any time assign to one or more Holders or other
institutions (each an "Assignee"), all, or any part (such portion to comprise an
aggregate outstanding principal amount of Commitments and/or interests in Notes
of not less than $1,000,000) of all, of its Notes of any Tranche together with a
proportionate part of its other rights and obligations under this Agreement, and
such Assignee shall assume such rights and obligations, pursuant to an
Assignment Agreement in substantially the form of Exhibit F hereto executed by
such Assignee and such transferor Holder (or, in the case of any Note held
through a global note, as described in Section 1.03, pursuant to such procedures
as may be required by the depository or nominee thereof), with notice to Savia
and the Paying Agent. Upon execution and delivery of such instrument and payment
by such Assignee to such transferor Holder of an amount equal to the purchase
price agreed between such transferor Holder and such Assignee, such Assignee
shall be a Holder party to this Agreement and shall have all the rights and
obligations of a Holder with a Commitment and/or Notes as set forth in such
instrument of assumption, and the transferor Holder shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required. Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Holder, the Paying Agent and
Savia shall make appropriate arrangements so that, if required, a new Note is
issued to the Assignee. In connection with any such assignment, the transferor
Holder shall pay to the Paying Agent an administrative fee for processing such
assignment in the amount of $3,000.

      (d) Maintenance of Registry. Each Issuer hereby designates the Paying
Agent to serve as such Issuer's agent, solely for purposes of this subsection


                                       79
<PAGE>

10.06(d), to maintain a register (the "Register") on which the Paying Agent will
record the name of each Holder, the aggregate principal amount of Notes
purchased by each Holder and each repayment in respect of the principal amount
of the Notes held by each Holder. Failure to make any such recordation, or any
error in such recordation, shall not affect either Issuer's obligations in
respect of such Notes. The entries in the Register shall be presumed correct
absent evidence to the contrary, and the Issuers, the Agents and the Holders
shall treat each Person in whose name a Note is registered as the owner thereof
for all purposes of this Agreement. With respect to any Holder, the assignment
or other transfer of the Commitments and/or Notes of such Holder and the rights
to the principal of, and interest on, any Note issued pursuant to this Agreement
shall not be effective until such assignment or other transfer is recorded on
the Register and, except to the extent provided in this subsection 10.06(d),
otherwise complies with Section 10.06, and prior to such recordation all amounts
owing to the transferor Holder with respect to such Commitments and Notes shall
remain owing to the transferor Holder. The registration of assignment or other
transfer of all or part of any Commitments and Notes for a Holder shall be
recorded by the Paying Agent on the Register. The Register shall be available at
the offices where kept by the Paying Agent for inspection by the Issuers and any
Holder at any reasonable time upon reasonable prior notice to the Paying Agent.
The Issuers may not replace any Holder pursuant to Section 8.06, unless, with
respect to any Notes held by such Holder, the requirements of this Section have
been satisfied. 

      (e) Certain Additional Restrictions on Transfer. In addition to the other
restrictions on transfers set forth herein, each Holder and Holder of an
interest in a Note (each participation or other interest in a Note, a "Note
Interest", and each Holder and other holder thereof, an "Interestholder"), by
its acceptance thereof, hereby agree to the following additional restrictions on
transfer with respect to the Notes and Note Interests, without regard to whether
the Notes or any Note Interests are "securities" as defined under the Securities
Act:

            (i) Each Interestholder understands that the Notes are being offered
      only in a transaction not involving any public offering within the meaning
      of the Securities Act, and that, if in the future such Interestholder
      decides to resell, pledge or otherwise transfer any of the Notes, such
      Notes may not be reoffered, resold, pledged or otherwise transferred
      except (i) to a person whom the Holder reasonably believes is a Qualified
      Institutional Buyer in a transaction meeting the requirements of Rule
      144A, (ii) in an offshore transaction complying with Rule 904 of
      Regulation S, (iii), pursuant to an exemption from registration under the
      Securities Act provided by Rule 144 thereunder (if available), (iv) to the
      Issuer of such Note or (v) pursuant to an effective registration statement
      under the Securities Act, and, in each case, in accordance with all
      applicable U.S. state securities laws.


                                       80
<PAGE>

            (ii) Each Interestholder may hold its interests in any Note through
      Euroclear, Cedel or another depository; provided no such Interestholder
      may grant any Participations in the interest so held through a depository.
      It is acknowledged that neither Euroclear nor Cedel will undertake to
      enforce the restrictions on transfer contained in this Section 10.06(e).
      Each Holder understands that the Notes will, unless otherwise agreed by
      the Issuer and the Interestholder thereof, bear a legend to the following
      effect:

         THIS NOTE (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE 
         U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, 
         ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE 
         TRANSFERRED WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR 
         BENEFIT OF, U.S. PERSONS, EXCEPT AS SET FORTH IN THE SECOND SENTENCE 
         HEREOF. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST 
         HEREIN, THE HOLDER (1) REPRESENTS THAT IT IS A "QUALIFIED 
         INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES 
         ACT) (A "QIB"), (2) AGREES THAT IT WILL NOT RESELL OR OTHERWISE 
         TRANSFER THIS NOTE EXCEPT (A) TO THE ISSUER OR ANY OF ITS 
         SUBSIDIARIES, (B) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS 
         A QIB PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB IN 
         A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (C) IN AN 
         OFFSHORE TRANSACTION MEETING THE REQUIREMENTS OF RULE 904 OF THE 
         SECURITIES ACT, (D) IN A TRANSACTION MEETING THE REQUIREMENTS OF 
         RULE 144 UNDER THE SECURITIES ACT, (E) IN ACCORDANCE WITH ANOTHER 
         EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT 
         (AND BASED UPON AN OPINION OF COUNSEL ACCEPTABLE TO THE ISSUER) OR 
         (F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN EACH 
         CASE, IN ACCORDANCE WITH THE APPLICABLE SECURITIES LAWS OF ANY STATE 
         OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND (3) 
         AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE OR AN 
         INTEREST HEREIN IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT 
         OF THIS LEGEND. AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION," 
         "U.S. PERSONS" AND "UNITED STATES" HAVE THE MEANINGS GIVEN TO THEM 
         BY RULE 902 OF REGULATION S UNDER THE SECURITIES ACT.

                     (iii) Each Interestholder (i) represents that it is not an
      "affiliate" (as defined in Rule 144 under the Securities Act) of the
      Company or acting on behalf of either Issuer and it is a Qualified
      Institutional Buyer within the meaning of the Rule 144A promulgated under
      the Securities Act and is aware that any sale of Notes to it will be made
      in reliance on Rule 144A. Such acquisition will be for its own account or
      for the account of another Qualified Institutional Buyer and (ii)
      represents that it is relying on the information contained in the Offering
      Memorandum in making its investment decision with respect to the Notes. It
      acknowledges that no representation or warranty is made by the Arrangers
      as to the accuracy or completeness of such materials. It further
      acknowledges that neither Issuer nor any of the Arrangers or any person
      representing the Issuers or the Arrangers have made any representation to
      it with respect to the Issuers or the offering or sale of any Notes other
      than the information contained in the Offering Memorandum. It has had
      access to such financial and other information concerning the Issuers and

<PAGE>

      of the Notes, including an opportunity to ask questions of and request
      information from the Issuers.

      (f) Any Holder may at any time assign all or any portion of its rights
under this Agreement and its Note to a Federal Reserve Bank. No such assignment
shall release the transferor Holder from its obligations hereunder.

      (g) No Assignee, Participant or other transferee of any Holder's rights
shall be entitled to receive any greater payment under Section 8.03 or 8.04,
8.05 than such Holder would have been entitled to receive with respect to the
rights transferred, unless such transfer is an assignment made with Savia's
prior written consent or is made by reason of the provisions of Section 8.02 or
8.03 requiring such Holder to designate a different Applicable Lending Office
under certain circumstances or at a time when the circumstances giving rise to
such greater payment did not exist.

      SECTION 10.07. Collateral. Each of the Holders represents to the Agent and
each of the other Holders that it in good faith is not relying upon any "margin
stock" (as defined in Regulation U) as collateral in the extension or
maintenance of the credit provided for in this Agreement.

      SECTION 10.08. Governing Law; Submission to Jurisdiction; Service of
Process. (a) This Agreement and the Notes shall be governed by and construed in
accordance with the laws of the State of New York.

      (b) Each of the parties hereto irrevocably submits to the jurisdiction of
the Supreme Court of the State of New York, County of New York, the U.S.
District Court for the Southern District of New York and any appellate court or
body thereto (collectively, the "New York Courts") and to the courts of its own
corporate domicile with respect to actions brought against it as a defendant,
over any suit, action or proceeding arising out of or relating to this Agreement
or the Notes. Each party hereto irrevocably waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of the venue of any such suit, action or proceeding brought in any such court,
any claim that any such suit, action or proceeding brought in such court has
been brought in an inconvenient forum and any right to which it may be entitled
on account of place of residence or domicile, and further agrees that a final
judgment in any such suit, action or proceeding brought in such court shall be
conclusive and binding such party.

      (c) Each Issuer hereby irrevocably appoints CT Corporation System, having
offices on the date hereof at 1633 Broadway, New York, New York 10019 (the
"Process Agent"), as its authorized agent to accept and acknowledge on its


                                       82
<PAGE>

behalf service of any and all process which may be served in any suit, action or
proceeding of the nature referred to above in any New York Court. Such
designation and appointment shall be irrevocable until all principal of and
interest on the Notes and other sums payable hereunder shall have been paid in
full in accordance with the provisions thereof and the Commitments shall have
been reduced to zero. Such Issuer covenants and agrees that it shall take any
and all reasonable action, including the execution and filing of any and all
documents, that may be necessary to continue the foregoing designations and
appointments in full force and effect and to cause the Process Agent to continue
to act in such capacity. Such Issuer covenants and agrees that, if the Process
Agent shall desire to cease so to act, prior to the Process Agent ceasing so to
act it shall irrevocably designate and appoint without delay another such agent
in such jurisdiction satisfactory to the Administrative Agent and, if requested
by the Administrative Agent, shall promptly deliver to the Administrative Agent
evidence in writing of such other agent's acceptance of such appointment in form
and substance reasonably acceptable to the Administrative Agent.

      (d) Each Issuer consents to process being served in any suit, action or
proceeding of the nature referred to in subsection (b) of this Section by
serving a copy thereof upon the Process Agent. Without prejudice to the
foregoing, the Administrative Agent agrees that to the extent lawful and
possible, written notice of said service upon the Process Agent shall also be
mailed by registered or certified airmail, postage prepaid, return receipt
requested, to such Issuer at its address specified in Section 10.01 hereof or to
any other address of which such Issuer shall have given written notice to the
Administrative Agent. If said service upon the Process Agent shall not be
possible or shall otherwise be impractical after reasonable efforts to effect
the same, such Issuer consents to process being served in any suit, action or
proceeding of the nature referred to in subsection (b) of this Section by the
mailing of a copy thereof by registered or certified airmail, postage prepaid,
return receipt requested, to the address of such Issuer specified in Section
10.01 hereof or to any other address of which such Issuer shall have given
written notice to the Administrative Agent, which service shall be effective 14
days after deposit in the United States Postal Service. Such Issuer irrevocably
waives, to the fullest extent permitted by law, all claim of error by reason of
any such service and such Issuer agrees that such service (i) shall be deemed in
every respect effective service of process upon such Issuer in any such suit,
action or proceeding and (ii) shall to the fullest extent permitted by law, be
taken and held to be valid personal service upon and personal delivery to such
Issuer.

      (e) Nothing in this Section shall affect any right of the Administrative
Agent to serve process in any manner permitted by law.

      SECTION 10.09. Counterparts; Integration; Effectiveness. This Agreement 
may be signed in any number of counterparts, each of which shall be an 
original, with the same effect as if the signatures thereto and hereto were 
upon the same instrument. This Agreement constitutes the entire agreement and 
understanding among the parties hereto and supersedes any and all prior 
agreements and understandings, oral or written, relating to the subject 
matter hereof. This Agreement shall become effective upon receipt by the 
Administrative Agent of counterparts hereof signed by each of the parties 
hereto (or, in the case of any party as to which an executed counterpart 
shall not have been received, receipt by the Administrative Agent in form 
satisfactory to it of telegraphic, telex, facsimile or other written 
confirmation from such party of execution of a counterpart hereof by such 
party).

      SECTION 10.10. WAIVER OF JURY TRIAL. EACH ISSUER, THE AGENTS AND THE
HOLDERS HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER FINANCING
DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

      SECTION 10.11. Conversion of Currencies. (a) If, for the purpose of
obtaining judgment in any court, it is necessary to convert a sum due hereunder
in Dollars into another currency, the parties hereto agree, to the fullest
extent that they may legally and effectively do so, that the rate of exchange
used shall be that at which in accordance with normal banking procedures the
Administrative Agent could purchase Dollars with such other currency in New
York, New York, on the Domestic Business Day immediately preceding the day on
which final judgment is given.

      (b) The obligation of each Issuer in respect of any sum due to any Holder
in Dollars shall, to the extent permitted by applicable law, notwithstanding any
judgment in a currency other than Dollars, be discharged only to the extent that
on the Domestic Business Day following receipt of any sum adjudged to be so due
in the judgment currency such Holder may in accordance with normal banking
procedures purchase Dollars in the amount originally due to such Holder with the
judgment currency. If the amount of Dollars so purchased is less than the sum
originally due to such Holder, each Issuer agrees, as to amounts owed by it
under this Agreement, as a separate obligation and notwithstanding any such
judgment, to indemnify such Holder against the resulting loss; and if the amount
of Dollars so purchased is greater than the sum originally due to such Holder,
such Holder agrees to repay such excess.

      SECTION 10.12. Waiver of Immunity. To the extent that either Issuer has or
hereafter may acquire any immunity from jurisdiction of any court or from any
legal process (whether through service or notice, attachment prior to judgment,
attachment in aid or execution, or otherwise) with respect to itself or its
property, such Issuer hereby irrevocably waives such immunity in respect of its
obligations hereunder and under the Notes to the extent permitted by applicable
law and, without limiting the generality of the foregoing, agrees that the
waivers set forth in this Section shall have effect to the fullest extent
permitted under the Foreign Sovereign Immunities Act of 1976 of the United
States of America and are intended to be irrevocable for purposes of such Act.
