                                 (Gerard Ridzon)


         THIS AGREEMENT is entered into effective the 10th day of November, 1998
by and between EMCON, a California corporation  ("Employer"),  and Gerard Ridzon
("Employee").

                                    RECITALS

         WHEREAS, the parties hereto desire to set forth the terms of Employee's
continued employment with Employer.

                                    AGREEMENT

         NOW, THEREFORE,  for good and valuable consideration,  receipt of which
is hereby acknowledged, the parties hereto hereby agree as follows:

         1.  Duties.  Employer  shall  employ  Employee as a Vice  President  of
Employer reporting directly to the Area Operations Manager for the North Area of
Employer's  Professional Services Division as presently configured (inclusive of
all office locations, Wehran of Puerto Rico, Airbank, the Clean Harbors alliance
and the  Xenergy  alliance)  and with such  duties and  responsibilities  as are
typical for an officer in a similar role.

         2. Term. Employee's employment pursuant to this Agreement will commence
on the date hereof and continue through January 3, 2002; provided, however, that
(i) this  Agreement  (except  Section 7  hereof)  shall  terminate  and be of no
further force or effect at the election of Employee,  upon violation by Employer
of its obligations hereunder or upon ninety (90) days advance notice by Employee
at any time after December 31, 1999, and (ii) this Agreement  (except Sections 6
and 7  hereof)  shall  terminate  and be of no  further  force or  effect at the
election  of  Employer  upon  termination  of  Employee's  employment  for cause
pursuant to Section 5, below.

         3.       Compensation.

                  (a) Employer  shall pay Employee a base salary  equivalent  to
$110,000  per  year,   in  equal   bi-weekly   installments   (less   applicable
withholding),  which salary may be adjusted upward, from time to time during the
term of this Agreement by Employer's Board of Directors.

                  (b) During  Employee's  full time  employment  with  Employer,
Employee shall be entitled to  participate  in all applicable  benefit plans and
bonus programs generally available to employees of Employer

                  (c) On the first  regular  pay day of January  1999 and on the
first  regular  pay day of each  applicable  year of the term of this  Agreement
(i.e. January 2000, January 2001, and January 2002). Employer shall pay Employee
a cash bonus of $50,000 per installment less applicable withholdings.

         4. Extent and Place of Services. During Employee's full time employment
with  Employer,  Employee  agrees to devote  Employee's  full  business  time to
employment with Employer. Employer shall


                                       80



not transfer or relocate Employee from Employer's office in New Hampshire during
the term hereof without the approval of Employee.  In the event of a relocation,
Employee  shall be entitled to receive  relocation  assistance  consistent  with
Employer's relocation policy.

         5.  Termination  of  Employment.   Employee's   employment  under  this
Employment Agreement shall not be terminated without good cause shown. Dismissal
for cause is intended to embrace intentional or grossly negligent conduct on the
part of  Employee  which is  materially  detrimental  to the  operations  and/or
reputation of Employer.  By way of illustration  such actions would include (but
would not be limited to) material  breach of Employee's  obligations  under this
Employment Agreement, and/or conviction of a crime (other than minor infractions
such as parking or similar traffic  violations),  moral turpitude and revocation
by the applicable licensing authority of professional licenses (if any) material
to Employee's ability to perform Employee's employment obligations.

         6. Covenant Not to Compete. In consideration for the hiring of Employee
by Employer  during the term of this  Agreement,  Employee  shall not render any
services  or engage in any  activities  which are  competitive  with  Employer's
activities in any other state in which Employer conducts business.  In the event
of  any  breach  of the  foregoing  covenant,  the  Employee  acknowledges  that
Employer's  remedies at law will be inadequate and Employer shall be entitled to
seek  injunctive  relief,  as well as any rights  Employer may have at law or in
equity, including any rights regarding the misuse of confidential or proprietary
information.

         7.  Confidentiality.  Employee  agrees  to  keep  confidential  and not
disclose  or make any use of any  confidential  or  proprietary  information  of
EMCON,  except for EMCON's  benefit,  at any time either during or subsequent to
Employee's employment. Confidential or proprietary information is subject matter
pertaining  to any  business of EMCON or any of their  clients,  consultants  or
affiliates  which  Employee  may produce,  obtain,  become aware of or otherwise
acquire during the course of employment which is not public knowledge.

         8.       Miscellaneous.

                  (a) This Agreement and each of its provisions shall be binding
upon and  inure to the  benefit  of the  parties  hereto  and  their  respective
successors, representatives, and assigns.

                  (b) This  Agreement  shall be  governed  by and  construed  in
accordance  with the laws of the State of  Delaware  as applied to  transactions
between Delaware residents wholly within the State of Delaware. If any provision
of the Agreement is held invalid or  unenforceable  for any reason,  the parties
hereto agree that such  invalidity  will not affect the remaining  provisions of
this Agreement.

                  (c) This Agreement  constitutes the entire  Agreement  between
the parties with respect to the subject  matter hereof and it hereby  supersedes
any and all prior agreements or understandings  between the parties with respect
to such subject  matter.  This Agreement may not be amended or changed except by
an instrument in writing signed by the parties hereto.

                  (d)  This   Agreement   may  be   executed   in  one  or  more
counterparts,  each of which shall be an original  instrument,  but all of which
together shall constitute one and the same instrument.

                  (e) The  headings of this  Agreement  have been  inserted  for
convenience of reference  only and shall in no way restrict or otherwise  modify
any of the terms or provisions hereof.


                                       81




         IN WITNESS WHEREOF,  the parties hereto have executed this Agreement as
