                                   ----------

                              EMPLOYMENT AGREEMENT

     Employment Agreement,  made this 29th day of April 1997, to be effective as
of September 1, 1996, by and between

                             Tirex America Inc.
                             3767 Thimens
                             Ville St. Laurent

                             Tirex Canada Inc.
                             3767 Thimens

                             Quebec, Canada H4R 1W4

                                                                (the "Company")*

                                       and

                             Vijay Kachru
                             513 Beaurepaire
                             Beaconsfield, Quebec
                             H9W 3C7

                                                                (the "Employee")

----------

     * Unless context  necessarily  implies otherwise,  all references herein to
the  "Company"  shall be to Tirex  America Inc.  and Tirex Canada Inc.,  and all
other  corporations,  partnerships,  or  other  entities,  now or in the  future
controlled  by, under common control with, or in control of, Tirex America Inc.,
jointly and severally.

     Whereas,  On  September  1, 1996 (the  "Effective  Date"),  pursuant to the
informal  consent of the  Executive  Committee  of the Board of Directors of the
Company,  Vijay Kachru was appointed as the Company's  Vice  President of Market
Development.   This   appointment   was   confirmed,   ratified,   and  adopted,
contemporaneously  herewith,  in the  written  unanimous  consent  of  the  said
Executive Committee of April 29, 1997.


                                       128

     Whereas, it has at all times since the Effective Date been the intention of
the parties to set forth the terms and  conditions  under which the Employee has
been  providing  services and receiving  compensation,  but  inadvertently  such
agreement was not put into writing prior to the date hereof;

     Whereas,  the  Company  and  the  Employee  desire  that  the  term of this
Agreement begin as at the Effective Date and continue for the three-year  period
ending on August 31, 1999;

     Whereas,  The  Company is a  "start-up"  company in its very early stage of
development,  with negligible or no hard assets, no income,  no operations,  and
only  limited  financial  resources  on hand to finance the  development  of its
technology and the commencement of operations.  Its future  financial  prospects
and position are therefore  highly  contingent and impossible to predict.  Based
upon the foregoing,  unregistered  shares of Tirex America's common stock, which
cannot be sold into the public  market for an  extended  period of time,  have a
value which reflects the Company's poor financial position and uncertain future,
and can be expected to be saleable by the Company, in arm's length transactions,
for not more  than  fifty  percent  (50%)  of the  current  market  value of the
publicly traded stock of Tirex America, or for substantially less.

     Now therefore,  in consideration of the premises and of the mutual promises
and covenants hereinafter set forth, the parties agree as follows:

1.  Employment

     The Company agrees to employ the Employee and the Employee agrees to accept
the employment described in this Agreement.

2.  Duties

     The  Employee  shall serve as Vice  President  of Market  Development,  her
powers  and  duties  in that  capacity  to be such as may be  determined  by the
President  and the Board of Directors  of the  Company.  During the term of this
agreement,  the Employee shall serve also, without additional  compensation,  in
such other  offices of the Company to which she may be elected or  appointed  by
the Board of  Directors.  With respect to all  capacities  in which the Employee
shall serve, she shall report solely to the President of the Company.

3.  Extent of Services

     The Employee shall devote her entire working time, attention,  and energies
to the  performance of her duties and shall not be engaged in any other business
activity,  whether or not pursued for gain  without the consent of the  Company.
The Employee  may invest her personal  assets in such form or manner as will not
require services on her part. The Employee shall at


                                       129

<PAGE>

all times  faithfully  and to the best of her ability  perform her duties  under
this  Agreement.  The duties shall be rendered at the Company's  office in Ville
St.Laurent,  Quebec,  or at such other  place or places and at such times as the
needs of the Company may from time-to-time dictate.

4.  Term

     The term of this  Agreement  shall be deemed to have begun on the Effective
Date,  and shall  continue  for the three year  period  which  commenced  on the
Effective  Date  and  shall  end on  August  31,  1999.  The  parties  presently
anticipate that the employment  relationship may continue beyond this three-year
term.  This  Agreement  shall not give the  Employee  any  enforceable  right to
employment beyond this term.

5.  Compensation

     As her entire compensation for the services to the Company, during the term
of this agreement,  in whatever capacity rendered,  the Company shall pay to the
Employee a salary in the following amounts:

     (a)  through and until March 31, 1998,  ninety  thousand  Canadian  dollars
          (CAN $90,000) per year:

     (b)  Commencing  as of  February 1, 1998,  ninety  thousand  United  States
          dollars (US $90,000) per year.

     The above stated  salary will be payable in  accordance  with the Company's
standard payroll procedures.  The Employee's performance shall be reviewed every
six months with  respect to her  eligibility  for  performance-based  raises and
bonuses, but there is no assurance or expectation that raises or bonuses will be
granted or paid.  Raises will be granted and bonuses will be paid, if at all, in
the sole discretion of the Board of Directors.

6.  Issuance of Stock in Lieu of Base Salary

     6.1 Compensation Shares. In the event that, from time to time, the Board of
Directors,  in its sole  discretion,  determines  that the Company does not have
adequate financial  resources to fully compensate the Employee in cash, then the
Company's  obligation to pay such compensation will be satisfied by the issuance
to the Employee of shares of the common stock of Tirex America, Inc., $.001, par
value,  per  share  ("Compensation   Shares"),  which  shares  shall  constitute
compensation pursuant to the terms of this Employee Agreement.

     6.2 Valuation.  All Compensation Shares will be issued to the Employee at a
value equal to fifty percent (50%) of the average of the high and low bid prices
of Tirex America's common


                                       130

<PAGE>

stock  as  traded  in the  over-the-counter  market  and  quoted  in the  NASDAQ
Electronic  Bulletin Board during the period when such Compensation  Shares were
earned,  or  such  other  value  which  the  Board  of  Directors,  in its  sole
discretion, shall determine.

     6.3 Registration Rights. From time to time, all or part of the Compensation
Shares may be registered by the Company under a  Registration  Statement on Form
S-8,  including  a  Re-offer  Prospectus,  as and at such  time as the  Board of
Directors of the Company or the executive committee thereof shall determine.

7.  Benefits

     The Employee  shall receive  medical and dental  insurance and other fringe
benefits  to the  extent  that such  benefits  are  provided  to all  full-time,
non-union employees of the Company.

8.  Expenses

     The Company  shall  reimburse  the  Employee  for  reasonable,  documented,
out-of-pocket expenses incurred by the Employee in fulfilling her duties.

9.  Termination

     9.1 For Cause.  The Company may terminate the Employee's  employment at any
time "for cause" with  immediate  effect upon  delivering  written notice to the
Employee.  For  purposes of this  Agreement,  "for  cause"  shall  include:  (a)
embezzlement,  theft, larceny, material fraud, or other acts of dishonesty;  (b)
material  violation by employee of any of her obligations  under this Agreement;
(c) conviction of or entrance of a plea of guilty or nolo contendere to a felony
or other crime which has or may have a material adverse effect on the Employee's
ability to carry out her duties under this  Agreement or upon the  reputation of
the Company; (d) conduct involving moral turpitude; (e) gross insubordination or
repeated  insubordination after written warning by the President of the Company;
or (f)  material  and  continuing  failure by the Employee to perform the duties
described in Section 2 above in a quality and  professional  manner for at least
thirty  (30)  days  after  written  warning  by the  Board of  Directors  or the
President of the Company.  Upon  termination  for cause,  the Company's sole and
exclusive obligation will be to pay the Employee her compensation earned through
the  date  of  termination,  and  the  Employee  shall  not be  entitled  to any
compensation after the date of termination.

     9.2 Upon Death. In the event of the Employee's death during the term of the
this  Agreement,  the Company's sole and exclusive  obligation will be to pay to
the Employee's  spouse,  if living,  or to her estate, if her spouse is not then
living, the Employee's compensation earned through the date of death.


                                       131

<PAGE>

     9.3 Upon  Disability.  The Company may terminate the Employee's  employment
upon the Employee's total disability. The Employee shall be deemed to be totally
disabled if she is unable to perform her duties  under this  Agreement by reason
of mental or  physical  illness or  accident  for a period of three  consecutive
months. Upon termination by reason of the Employee's  disability,  the Company's
sole and  exclusive  obligation  will be to pay the  Employee  her  compensation
earned through the date of termination.

     9.4 Without  Cause.  The Company may  terminate the  Employee's  employment
without  cause at any  time  after  expiration  of the  three-year  term of this
Agreement.

10.  Covenant Not to Compete

     10.1 Covenant. At all times during the terms of this Agreement,  during any
period  following the term of this Agreement when the Employee shall continue to
be employed by the Company in any capacity  whatsoever,  and during the one year
period after the Employee's  employment  with the Company has been terminated by
either party and for any reason, the Employee will not directly or indirectly:

     (a)  enter  into or attempt to enter  into the  "Restricted  Business"  (as
          defined below) in the continental United States or Canada;

     (b)  induce or attempt to persuade any former,  current or future employee,
          agent,  manager,  consultant,  director,  or other  participant in the
          Company's  business to terminate such employment or other relationship
          in order  to  enter  into any  relationship  with  the  Employee,  any
          business  organization  in which the Employee is a participant  in any
          capacity whatsoever, or any other business organization in competition
          with the Company's business; or

     (c)  use contracts,  proprietary information,  trade secrets,  confidential
          information,   customer  lists,  mailing  lists,  goodwill,  or  other
          intangible  property used or useful in  connection  with the Company's
          business.


     10.2  Indirect  Activity.  The term  "indirectly,"  as used in Section  7.1
above,  includes  acting  as  a  paid  or  unpaid  director,   officer,   agent,
representative,  employee of, or  consultant to any  enterprise,  or acting as a
proprietor of an enterprise,  or holding any direct or indirect participation in
any  enterprise  as  an  owner,  partner,   limited  partner,   joint  venturer,
shareholder,  or  creditor,  except a 10% or less equity  position in a publicly
traded company.

     10.3 Restricted Business. The term "Restricted Business" means any business
related to the  disintegration of scrap tires, the manufacture of equipment used
for  such  purpose,  or the  sale  or  brokerage  of the  by-products  from  the
disintegration of scrap tires. Nevertheless,  the Employee may own not more than
five percent of the outstanding equity securities of a


                                       132

<PAGE>

corporation that is engaged in the Restricted  Business if the equity securities
are listed for trading on a national stock exchange or are registered  under the
Securities Exchange Act of 1934.

11.  Severability

     The  covenants set forth in Section 10 above shall be construed as a series
of separate  covenants,  one for each county in each of the states of the United
States and one for each of the analogous  jurisdictions  in Canada to which such
restriction  applies.  If,  in any  judicial  proceeding,  a court of  competent
jurisdiction  shall  refuse to  enforce  any of the  separate  covenants  deemed
included in this Agreement,  or shall find that the term or geographic  scope of
one or more of the separate  covenants is unreasonably  broad, the parties shall
use their best good faith efforts to attempt to agree on a valid provision which
shall be a reasonable  substitute for the invalid provision.  The reasonableness
of the substitute  provision  shall be considered in light of the purpose of the
covenants  and the  reasonable  protectable  interests  of the  Company  and the
Employee. The substitute provision shall be incorporated into this Agreement. If
the parties are unable to agree on a substitute  provision,  then the invalid or
unreasonably  broad provision shall be deemed deleted or modified to the minimum
extent necessary to permit enforcement.

12.  Confidentiality

     The  Employee  acknowledges  that  she  will  develop  and  be  exposed  to
information that is or will be confidential and proprietary to the Company.  The
information includes customer lists,  technology designs, plans and information,
marketing plans,  pricing data,  product plans,  software,  and other intangible
information.  Such  information  shall be deemed  confidential to the extent not
generally  known  within  the  trade.  The  Employee  agrees to make use of such
information  only in the  performance  of her duties  under this  Agreement,  to
maintain such  information in confidence and to disclose the information only to
persons with a need to know.

13.  Remedies

     The Employee  acknowledges  that  monetary  damages  would be inadequate to
compensate the Company for any breach by the Employee of the covenants set forth
in Sections 10 and 12 above.  The  Employee  agrees  that,  in addition to other
remedies  which  may be  available,  the  Company  shall be  entitled  to obtain
injunctive  relief  against  the  threatened  breach  of this  Agreement  or the
continuation  of any breach,  or both,  without the necessity of proving  actual
damages.


                                       133

<PAGE>

14.  Waiver

     The waiver by the Company of the breach of any provision of this  Agreement
by the Employee  shall not operate or be construed as a waiver of any subsequent
breach by the Employee.

15.  Assignment

     This  Agreement  may be  assigned  by the  Company  as part of the  sale of
substantially all of its business;  provided,  however, that the purchaser shall
expressly  assume all obligations of the Company under this Agreement.  Further,
this Agreement may be assigned by the Company to an affiliate, provided that any
such affiliate shall expressly  assume all obligations of the Company under this
Agreement,  and provided further that the Company shall then fully guarantee the
performance  of the Agreement by such  affiliate.  Employee  agrees that if this
Agreement is so assigned,  all the terms and conditions of this Agreement  shall
obtain  between  such  assignee and himself with the same force and effect as if
said  Agreement  had been made with such  assignee in the first  instance.  This
Agreement is personal to the Employee and shall not be assigned  without written
consent of the Company.

16.  Notices

     All notices  required or permitted to be given hereunder shall be mailed by
certified mail, or delivered by hand or by recognized  overnight  courier to the
party to whom such notice is required or permitted to be given hereunder, in all
cases with written proof of receipt required. Any such notice shall be deemed to
