Mr. David M. Sucniak
1145 Hambiltonian Way
York, PA  17404

Dear Mr. Suchniak:

This letter  contains the terms and conditions of your Offer of Employment  with
our  Company.  A more  detailed  Employment  Agreement  (Contract)  will  follow
shortly.  However,  we felt it important to document the  information  contained
herein as quickly as possible.

Your initial  employment,  beginning  July 1, 1998,  will be as Chief  Financial
Officer/Senior  Vice President of Agro Power  Development,  Inc. You will report
directly to the Chief  Executive  Officer of APD,  Inc. As soon as the  proposed
merger between APD, Inc. and EcoScience Corporation is complete, expected in the
third  quarter of this year,  you will be come CFO/VP of the new public  company
and report directly to the CEO of that company.

Your duties and  responsibilities in these positions will be consistent with the
duties  and  responsibilities  normally  assigned  to a CFO of a  publicly  held
company.  These will include, but may not be limited to oversight and management
of the Accounting  Department(s),  management of all corporate  finance matters,
oversight and management of the Treasury  function,  oversight and management of
the Management  Information Systems functions and management of all required SEC
filings and reports. In sum, you will have accountability for all company fiscal
matters.  Specific goals and targets for achievement will be mutually determined
by you and the CEO within ninety (90) days of your initial employment with us.

You agree  that you will not  engage  in  consulting  work or any other  type of
business for your own benefit with other  companies  nor will you agree to serve
on any company's Board of Directors without the explicit approval of the CEO.

Your  starting  salary  will be  $160,000.00/year.  This  will be  increased  to
$170,000.00/year  on  January  1,  1999 or after six (6)  months  of  continuous
service with our company,  whichever occurs first. In addition,  we will provide
you a monthly Vehicle Allowance in the amount of $500.00; this will be increased
to  $600.00/month  on  January  1,  1999 or after six (6)  months of  continuous
service,  whichever  comes first.  Finally,  we will pay you a Signing  Bonus of
$10,000.00 within fifteen (15) days of your employment commencement date.

You  will be  eligible  to  receive  an  Incentive  Bonus  beginning  in  fiscal
(calendar)  year  1999.  The  amount  of this  annual  bonus  will be  based  on
quantitative  and  qualitative  objectives to be established by you and the CEO.
The  target  threshold  for this  bonus  plan will be 25% of your  base  salary.
Additionally, we will create an Incentive Stock Option Plan for Executives which
we expect to be in place by  January  1,  1999.  The  actual  amount of  options
granted,  and  their  price,  will be  determined  by the CEO and the  Board  of
Directors and will be commensurate with your position in the company.

Effective  January 1, 1999 you will be eligible  for  fifteen  (15) days of paid
vacation per year.  You will be eligible for eight (8) days of paid vacation for
the remainder of 1998.

You will be eligible to  participate  in our various  Benefit Plans  immediately
upon your commencement of employment.  The company pays the major portion of the
premiums for you and your dependents for both our Medical and Dental Plans. Your
approximately costs would be $311.00/month for medical coverage and $30.00/month
for dental coverage.  The plans are voluntary.  Should you choose to participate
the payments are made through pre-tax  payroll  deductions.  Additional  details
regarding this coverage,  including  enrollment forms, will be sent to you under
separate cover.

Also, the company will provide,  at no cost to you, Life Insurance.  The benefit
of this insurance is equal to one times (1X) your annual salary. In addition you
will be  covered,  again at no coast to you,  under  our  Accidental  Death  and
Dismemberment Policy.

The Company sponsors a 401(k) plan which is managed by Franklin-Templeton Funds.
Currently the company does not  contribute to this plan;  however,  we encourage
all eligible employees to participate. Enrollment in the 401(k) plan is open the
first day of each calendar quarter, i.e. July 1, Oct. 1, etc.

In your  position  you will be expected to develop an Expense  Budget  primarily
covering  travel and  entertainment  expenses.  These  expenses  are  reimbursed
through  our  normal  Expense   Reporting  Process  and  generally  require  the
submission of relevant receipts.

It is  recognized  that you will have to  relocate  your  residence  in order to
accept this position.  In  consideration  of this the company will reimburse you
the following expenses regarding your relocation:

     -    All fees associated with selling your current home, including any real
          estate  fee you must pay (to a maximum of 6% of the  selling  price of
          your home)

     -    Costs associated with the purchase of a new home including attorney or
          bank fees,  inspections,  etc...(Not  to include the cost of "mortgage
          points.")

     -    Any costs  associated  with moving your household  goods from your old
          residence to your new home.

     -    The cost of a "house  hunting"  trip for you and your  family in order
          for you to find a new home.  This trip  should not exceed one week and
          we will reimburse expenses such as lodging, meals, etc.

     -    The company will  reimburse  you any expenses you incur as a result of
          tax liabilities related to relocation payments. This reimbursement may
          take the form of "grossup"

                                                                          Page 3

          payments  to  cover  your  tax  costs or may be  covered  through  the
          utilization of a third-party relocation company.

Should you require a temporary living  arrangement prior to actually moving into
your new residence we will pay you at the rate of $125.00/day to cover the costs
of this temporary  arrangement.  This is intended to cover the costs of lodging,
food,  rental  automobile and any other  miscellaneous  expenses you might have.
This Interim  Living  provision  is in effect  until  October 1, 1998 or sooner,
should you finalize your relocation prior to that date.

As noted above we will have a Stock Option Plan in place shortly.  Should you be
terminated by the company  prior to the  implementation  of that plan,  and your
vesting  within the plan,  and without  cause,  the company  agrees to pay you a
separation  allowance  equal to twelve (12)  month's  base pay.  This  provision
becomes null and void after the Stock Option Plan has been put in place.

A more detailed Employment  Agreement will be provided shortly. If, based on the
information in this letter,  you wish to accept this position please indicate by
signing  below,  as  noted,  and  returning  a copy  of this  letter  as soon as
possible.

We are eager to have you on the team! If you have any questions please call.
