protect the rights of CoBank and any such Participant with respect thereto. The
term "GUARANTEED OBLIGATIONS" as used in this Guaranty shall mean such
indebtedness, obligations and liabilities described above in this Article 2.

     3. GUARANTY OF PAYMENT; WAIVER OF DEFENSES, ETC.

          3.1 GENERAL. This Guaranty is a guarantee of payment and not of
collection, and Guarantor waives any right to require that any action be brought
against Borrower or to require that resort be had at any time to any direct or
indirect security for the Guaranteed Obligations. Guarantor's obligations
hereunder are continuing obligations and are absolute and unconditional
irrespective of the genuineness, validity or enforceability of any instrument or
instruments now or hereafter evidencing any Guaranteed Obligation or any part
thereof (including but not limited to the Loan Documents) or of any other
agreement now or hereafter entered into by CoBank and Borrower pursuant to which
any Guaranteed Obligation or any part thereof is issued, or of any other
circumstance which might otherwise constitute a legal or equitable discharge of
a guarantor or surety. Guarantor's obligations hereunder shall continue in full
force and effect as long as any Guaranteed Obligation or any part thereof
remains outstanding and unpaid or CoBank has any obligation to make any
extension of credit to Borrower pursuant to any of the Loan Documents.

          3.2 WAIVERS. With respect to its obligations under this Guaranty,
Guarantor waives any and all defenses and discharges available to a guarantor,
surety, endorser or accommodation party, dependent upon its character as such.
Guarantor hereby waives presentment for payment, notice of nonpayment, demand
and protest. Guarantor agrees that its obligations hereunder shall not be
affected or impaired in any way by any of the following acts or things (which
CoBank may do from time to time without notice to Guarantor): (a) any amendment
(including, without limitation, an amendment increasing the interest rate),
modification or extension of any Loan Documents, or any waiver of compliance by

                                       6

<PAGE>

foregoing; (b) any sale, pledge, surrender, compromise, settlement, release,
renewal, extension, indulgence, alteration, substitution, exchange, modification
or other disposition of any Guaranteed Obligation or any collateral therefor;
(c) any acceptance or release of collateral for, or guarantors of, any
Guaranteed Obligation; (d) any inability, failure, neglect or omission to
obtain, perfect, enforce or realize upon any collateral for any of the
Guaranteed Obligations, or to exercise any lien upon or right of appropriation
of any moneys, credits or property to the liquidation of any Guaranteed
Obligation, or to pursue or obtain any deficiency judgment against Borrower
following any foreclosure of any security interest, mortgage or deed of trust
granted by Borrower to CoBank; or (e) any application of payments or credits
upon the Guaranteed Obligations under the Loan Documents. CoBank shall not be
required, before exercising its rights under this Guaranty, to first resort for
the payment of any Guaranteed Obligation to Borrower, or other guarantors or
sureties or accommodation parties or any collateral, property, liens or other
remedies or rights whatsoever. With respect to its obligations under this
Guaranty, Guarantor agrees not to exercise any right of contribution, recourse,
subrogation or reimbursement available to Guarantor against Borrower or any
other Person or entity or property unless and until all the Guaranteed
Obligations have been indefeasibly paid in full and there is no obligation of
CoBank to make any extension of credit to Borrower under the Loan Documents.
Guarantor hereby waives any rights it may have at equity or in law to require
CoBank to apply any rights of marshalling or other equitable doctrines in the
circumstances.

          3.3 AMOUNT OF INDEBTEDNESS. CoBank may, at its sole option and without
any notice to or consent of Guarantor, allow the Indebtedness of Borrower owed
to CoBank to exceed the principal amount of all promissory notes executed by
Borrower in connection with the Indebtedness without in any way adversely
affecting Guarantor's liability hereunder.

          3.4 SUBROGATION. After all Guaranteed Obligations have been
indefeasibly paid in full and there is no obligation of CoBank to make any
extension of credit to a Borrower under the Loan Documents, Guarantor shall have
and may exercise rights of subrogation against Borrower.

          3.5 SUBORDINATION OF OTHER DEBT. Any indebtedness or obligation of
Borrower, or any other claim against or liability of Borrower, now or hereafter
held by or owed to Guarantor ("GUARANTOR'S CLAIMS") is hereby subordinated by
Guarantor to the Indebtedness; and such Guarantor's Claims, if CoBank so
requests, shall be collected, enforced and received by Guarantor as trustee for
CoBank and paid over to CoBank on account of the Indebtedness.

          3.6 LIENS AND RIGHTS OF SET-OFF. In addition to all Liens upon, and
right of set-off against, the property of Guarantor existing under applicable
law, CoBank may, without demand or notice of any kind, and at any time when any
amount shall be due and payable hereunder by Guarantor, appropriate and apply
toward the payment of such amount, in such order of application as CoBank may
elect, any property, balances, credits, deposits, accounts or moneys of
Guarantor in the possession or control of CoBank for any purpose. Guarantor
hereby grants to CoBank a right of set-off and a

                                       7

<PAGE>

security interest in such property and funds in the possession or control of
CoBank. Guarantor further expressly grants to CoBank the right, to be exercised
at the discretion of CoBank, to file one or more financing statements under the
Uniform Commercial Code naming Guarantor as debtor and CoBank as secured party
with respect to such property and funds and Guarantor hereby agrees to sign any
such statement.

     4. RECOVERY OF PAYMENT. If any payment received by CoBank and applied to
the Guaranteed Obligations is subsequently set aside, recovered, rescinded or
required to be returned for any reason (including, without limitation, the
bankruptcy, insolvency or reorganization of Borrower), the Guaranteed
Obligations to which such payment was applied shall, for the purposes of this
Guaranty, be deemed to have continued in existence, notwithstanding such
applications, and this Guaranty shall be enforceable as to such Guaranteed
Obligations as fully as if such applications had never been made.

     5. INFORMATION REGARDING BORROWER. Guarantor assumes full responsibility
for keeping fully informed of the financial condition of Borrower and all other
circumstances affecting Borrower's ability to pay and perform its obligations
under the Loan Documents and agrees that CoBank shall not have any duty to
report to Guarantor any information which CoBank receives about the financial
condition of Borrower or any circumstances bearing on the ability of Borrower to
perform its obligations under the Loan Documents, and Guarantor hereby expressly
and unconditionally waives any defense based on the failure of CoBank to report
such information.

     6. SECURITY. As security for the payment and performance of Guarantor's
obligations under this Guaranty, Guarantor shall grant to CoBank and maintain
for CoBank, a first Lien on all of Guarantor's stock in APD, whether now owned
or held or hereafter acquired (the "GUARANTOR COLLATERAL"). Guarantor has
executed and delivered to CoBank the Guarantor Security Documents as required
under this Guaranty to evidence the Lien of CoBank in the Guarantor Collateral,
and the terms, provisions and conditions of the Guarantor Security Documents are
hereby incorporated in this Guaranty and made a part hereof. Guarantor shall
also execute such further security agreements, stock powers, financing
statements, assignments or other documents as CoBank shall request, in form and
substance as such CoBank shall specify, to establish, confirm, perfect or
provide notice of CoBank's Lien on the Guarantor Collateral.

          7.18 CAPITALIZATION. The authorized capital stock and the issued and
outstanding shares of APD, and the securities certificates representing such

          7.19 YEAR 2000. Guarantor has (i) initiated a review and assessment of
all areas within its business and operations (including those affected by

that the Significant Software used by Guarantor or Guarantor's Mission Critical
suppliers, vendors and customers may not be Year 2000 Compliant, (ii) developed
a plan and timetable for remediation of Guarantor's Significant Software that
may not be Year 2000 Compliant and for the development of contingency plans in

to date, implemented that plan in accordance with such

                                       11

due inquiry, the impact of the year 2000 on Guarantor and the Mission Critical
customers and suppliers of Guarantor will not be such as to have a Material
Adverse Effect on Guarantor.

          7.20 DISCLOSURE. Neither the representations and warranties contained
in this Article 7 nor any information, exhibit or report furnished by Guarantor
to CoBank in connection with the negotiation and preparation of this Guaranty or

respects in accordance with the terms of such plan and with ERISA, the Code, and
any other applicable law, except to the extent any failure to comply with the

amount as may be needed to pay in full all amounts owing under the Loan
Agreement) related to such Stock Event shall be paid to CoBank by Guarantor (or
the relevant subsidiary), within one Business Day of receipt thereof, to reduce
the outstanding balance of the Loans. As used in the foregoing sentence, "Net
Proceeds" shall mean all cash proceeds related to a Stock Event, less reasonable
transaction expenses.

     9. NEGATIVE COVENANTS OF GUARANTOR. From and after the date of this
Guaranty and until the Guaranteed Obligations are indefeasibly paid in full and
CoBank does not have any obligation to make any extension of credit to Borrower,

days' prior written notice to CoBank, and furnishing CoBank with such documents
as CoBank may request pursuant to Section 8.8 hereof prior to taking any such
action, Guarantor shall not change its name, identity or corporate structure, or
the location of its place of business (or chief executive office if more than
one place of business).

          9.5 ERISA. Guarantor shall not: (a) engage in or permit any
transaction which could result in a "prohibited transaction" (as such term is
defined in Section 406 of ERISA) or in the imposition of an excise tax pursuant

in any liability to the PBGC. As used in this Section, all terms enclosed in
quotation marks shall have the meanings set forth in ERISA. Guarantor's failure
to comply with any of the foregoing provisions of this Section shall not
constitute a breach of this Guaranty unless such failure has a Material Adverse
Effect on Guarantor.

<PAGE>

     10. INDEMNIFICATION.

          10.1 GENERAL; STAMP TAXES; INTANGIBLES TAX. Guarantor agrees to
indemnify and hold CoBank, each Participant and their directors, officers,
employees, agents, professional advisers and representatives ("INDEMNIFIED
Parties") harmless from and against any and all claims, damages, losses,
liabilities, costs or expenses whatsoever which any Indemnified Party may incur
(or which may be claimed against any such Indemnified Party by any Person),
including attorneys' fees incurred by any Indemnified Party, arising out of or
resulting from: (a) the material inaccuracy of any representation or warranty
made by Borrower, APD, VFIFA, General Partner or Guarantor in any Loan Document;
(b) the material failure of Borrower, APD, VFIFA, General Partner or Guarantor
to perform or comply with any covenant or obligation of Borrower, APD, VFIFA,
General Partner or Guarantor under any Loan Document; or (c) the exercise by
CoBank of any right or remedy set forth in this Guaranty or any other Loan
Document, provided that Guarantor shall have no obligation to indemnify any
Indemnified Party against claims, damages, losses, liabilities, costs or
expenses to the extent that a court of competent jurisdiction renders a final
non-appealable determination that the foregoing are solely the result of the
willful misconduct or gross negligence of such Indemnified Party. In addition,
Guarantor agrees to indemnify and hold the Indemnified Parties harmless from and
against any and all claims, damages, losses, liabilities, costs or expenses
whatsoever which CoBank or any other Indemnified Party may incur (or which may
be claimed against any such Indemnified Party by any Person), including
attorneys' fees incurred by any Indemnified Party, arising out of or resulting
from the imposition or nonpayment by Guarantor, Borrower, APD, VFIFA or General
Partner of any stamp tax, intangibles tax, or similar tax imposed by any
governmental authority, including any amounts owing by virtue of the assertion
that the property valuation used to calculate any such tax was understated.
Guarantor shall have the right to assume the defense of any claim as would give
rise to Guarantor's indemnification obligation under this Section with counsel
of Guarantor's choosing so long as such defense is being diligently and properly
conducted and Guarantor shall establish to the Indemnified Party's satisfaction
that the amount of such claims are not, and will not be, material in comparison
to the liquid and unrestricted assets of Guarantor available to respond to any
award which may be granted on account of such claim. So long as the conditions
of the preceding sentence are met, the Indemnified Party shall have no further
right to reimbursement of attorneys' fees incurred thereafter. The obligation to
indemnify set forth in this Section shall survive the termination of this
Guaranty.

     11. MISCELLANEOUS.

          11.1 LOAN DOCUMENTS. Guarantor has received and reviewed the Loan
Agreement and the other Loan Documents and acknowledges, agrees, and consents to

Guarantor whether or not any other guarantors execute any guarantees of the
Indebtedness.

                                       17

<PAGE>

          11.3 NO WAIVER BY COBANK . No delay or failure by CoBank to exercise
any right or remedy against Guarantor will be construed as a waiver of that
right or remedy. All remedies of CoBank against Guarantor are cumulative.
Failure or delay on the part of CoBank to exercise any such right or remedy
shall not operate as a waiver thereof. Any single or partial exercise by CoBank
of any such right or remedy shall not preclude any future exercise thereof or
the exercise of any other right or remedy.

          11.4 ASSIGNMENT. Guarantor may not assign this Guaranty without the
written consent of CoBank. Subject to the foregoing, the provisions of this
Guaranty shall be binding upon Guarantor, its successors and assigns. CoBank
may, without notice to or consent from Guarantor, assign all or any part of the
Guaranteed Obligations or any security therefor. In the event of such
assignment, each and every immediate and successive assignee, transferee or
holder of all or any part of the Guaranteed Obligations shall have the right to
enforce this Guaranty, by legal action or otherwise, for its benefit, as fully
as if such assignee, transferee or holder were named herein and specifically
given such rights and power. Notwithstanding such sale, assignment, or transfer,
CoBank shall have an unimpaired right to enforce this Guaranty for its own
benefit as to any portion of the Guaranteed Obligations not sold, transferred or
assigned, or which CoBank may have reacquired after such sale, transfer or
assignment.

          11.5 SEVERABILITY. The invalidity or unenforceability of any one or
more provisions of this Guaranty will not affect any other provision of this
Guaranty. In the case of such invalidity or unenforceability, this Guaranty
shall be construed as if the invalid or unenforceable provisions had not been
included herein.

          11.6 AMENDMENTS. This Guaranty may not be amended without the written
consent of CoBank and Guarantor. Guarantor agrees that it shall reimburse CoBank
and any Participant for all fees and expenses incurred in retaining outside
legal counsel in connection with any amendment or modification to this Guaranty
requested by Guarantor.

          11.7 SERVICE OF PROCESS AND CONSENT TO JURISDICTION. Guarantor
irrevocably agrees that any litigation with respect to this Guaranty or any
other Guarantor Document or to enforce any judgment obtained against Guarantor
for breach of this Guaranty or the other Guarantor Documents may be brought in
the courts of the State of Colorado and in the United States District Court for
the District of Colorado (if applicable subject matter jurisdictional
requirements are present), as CoBank may elect; and, by execution and delivery
of this Guaranty, Guarantor irrevocably submits to such jurisdiction. With
respect to litigation concerning this Guaranty or the other Guarantor Documents
within the jurisdiction of the courts of the State of Colorado or the United
States District Court for the District of Colorado, Guarantor hereby irrevocably
appoints, until January 31, 2005, The Corporation Company, 1675 Broadway,
Denver, Colorado 80202, as the agent of Guarantor to receive for and on behalf
of Guarantor, service of process, which service may be made by mailing a copy of
any summons or other legal process to Guarantor in care of such agent. Guarantor
agrees that Guarantor shall maintain a duly appointed agent for service of
summons and other legal process as

                                       18

<PAGE>

long as Guarantor remains obligated under this Guaranty. The receipt by such
agent and/or by Guarantor of such summons or other legal process in any such
litigation shall be deemed personal service and acceptance by Guarantor for all
purposes of such litigation. Guarantor agrees that a final judgment in any such
action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

          11.8 JURY WAIVER. IT IS MUTUALLY AGREED BY AND BETWEEN COBANK AND
GUARANTOR THAT THEY EACH WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR
COUNTERCLAIM BROUGHT ON ANY MATTER WHATSOEVER ARISING OUT OF OR IN ANY WAY
CONNECTED WITH THIS GUARANTY OR THE GUARANTOR SECURITY DOCUMENTS.

          11.9 RELEASE. GUARANTOR HEREBY RELEASES, WAIVES AND FOREVER DISCHARGES

              time from the issuance of Note B until January 30, 2001, by giving
              written notice to EcoScience, to convert its right to receive
              payment of the amounts due under Note B (including any accrued
              interest thereon) into a number of shares of Common Stock that
              shall be calculated in accordance with paragraph (c)below.  Within
              eight business days after such notice, EcoScience shall deliver a
              stock certificate representing the applicable number of shares of
              Common Stock to ABV.  Upon such delivery, ABV shall be deemed to
              have assigned and transferred to EcoScience all of its right,
              title and interest in Note B.

     (b)      VFLP and EcoScience agree that in the event any monthly
              installment of principal under Note A or Note B is not paid within
              thirty (30) days of when due, ABV shall have the option, at any
              time until the full payment and satisfaction of such overdue
              amount (including any accrue interest thereon), by giving written
              notice to EcoScience, to convert its right to receive payment of

              number of shares of Common Stock that shall be calculated in
              accordance with paragraph (d) below.  Within eight business days
              after such notice, EcoScience shall deliver a stock certificate
              representing the applicable number of shares of Common Stock to
              ABV.  Upon such delivery, ABV shall be deemed to have assigned and
              transferred to EcoScience all of its right to collect the overdue
              amount of principal and interest thereon under the applicable
              Note.

     (c)      The number of shares of Common Stock into which ABV shall have
              the right to convert its rights under Note B pursuant to
              paragraph (a) shall be calculated by dividing (i) the amount
              due under Note B (including any accrued interest thereon) at
              the time of conversion by (ii) $1.12 (the "Note B Conversion
              Price").

     (d)      The number of shares of Common Stock into which ABV shall have
              the right to convert its right to receive any overdue amount
             (including interest thereon) pursuant to paragraph (b) shall
              be calculated by dividing (i) the amount of overdue principal
              and interest thereon at the time of conversion by (ii) $1.00
             (the "Default Conversion Price").

     (e)      The Note B Conversion Price and the Default Conversion Price
              shall be equitably adjusted to reflect the terms of any stock
              split, reverse stock split, stock dividend, reclassification,
              reorganization or similar transaction. No fractional shares
              shall be issued pursuant to this Section 10; rather, the
              number of shares issuable pursuant to this Section 10 shall be
              rounded to the nearest whole share.
