hereunder, effective upon the giving of such notice. Upon such termination, the

forms of designation of beneficiary or beneficiaries. The Employee's designated

Company of and from any further obligations under this Agreement. Any other
benefits due under applicable plans and programs of the Company shall be
determined under the provisions of such plans and programs.

      8. Termination and Expiration of Employment.

            (a) The Employee's employment hereunder may be terminated by the
Company for "cause" at any time. Termination of employment for "cause" shall
mean termination upon (1) the willful failure by the Employee to materially
perform his duties with the Company or to follow the instructions of the Board
(other than any such failure resulting from his incapacity due to physical or
mental illness), (2) the willful engaging by the Employee in conduct that is
materially injurious to the Company, monetarily or otherwise, (3) the commission
of any act of fraud, theft or dishonesty by the Employee against the Company,
(4) the conviction of the Employee of (or the pleading by the Employee of nolo
contendere to) any felony, fraud or embezzlement or (5) any willful breach by
the Employee of the terms of this Agreement, unless any such breach of this
Agreement by the Employee that is capable of being corrected is corrected in all
material respects within thirty (30) days following written notification by the
Company to the Employee that the Company intends to terminate the employment of
Employee hereunder by reason of a willful breach of this Agreement for cause as
specified in such written notice to the Employee.

            If the Employee is terminated for "cause," the Company shall have no
further obligations under this Agreement, except for the obligation to pay all
salary and other benefits earned but unpaid to the date of termination, and all
options granted to the Employee and not exercised prior to the date of such
termination shall be extinguished on the date of such termination.

            (b) If (i) the Company terminates the employment of the Employee
during the Term other than for "cause" (as defined in Paragraph 8(a) of this
Agreement), or (ii) during the Term there is a change in control of the Company
and the successor entity (or purchaser) does not accept an assignment of this
Agreement, or (iii) the terms of the Employee's employment are materially
adversely changed or his duties and responsibilities are materially diminished,
following a change of control or otherwise (including, by way of example and not
by limitation, by reason of the Employee ceasing to be an Executive Vice
President and Chief Operating Officer of the Company), whereupon, in the case of
this clause (iii), the Employee shall have the right to consider his employment
hereunder to have been terminated by the Company by giving written notice to the
Company within 10 business days after the date on which the Employee believes
that such adverse change has occurred, the action(s) constituting such adverse
change or diminution, and the fact that he is terminating this Agreement
pursuant to this Paragraph 8(b)(iii), then (A) the Company shall retain Employee
and Employee agrees to serve as a consultant to the Company for the longer of
the remainder of the Term or six (6) months ("Consulting Period"); 


                                      -4-
<PAGE>

(B) the Employee's options shall vest as set forth in Section 4(c) above; and
(C) the Employee shall be entitled to continue to receive (1) on the same
schedule as was in existence prior to such termination, payment of his base
salary and all other benefits to which he is entitled for the Consulting Period
and (2) the pro rata portion of any bonus earned by the Employee for the fiscal
year in which the termination occurred.

      9. Confidentiality; Injunctive Relief.

            (a) Recognizing that the knowledge, information and relationship
with customers, suppliers and agents, and the knowledge of the Company's
business methods, systems, plans and policies which he may hereafter receive or
obtain as an employee of the Company, are valuable and unique assets of the
Company, the Employee agrees that, during and after the Term, he shall not
(otherwise than pursuant to his duties hereunder) disclose, without the prior
written approval of the Board, any such knowledge or information pertaining to
the Company, its business, personnel or policies, to any person, firm,
corporation or other entity, for any reason or purpose whatsoever. The
provisions of this Paragraph 9(a) shall not apply to (i) information which is or
shall become generally known to the public or the trade, or information which is
or shall become available in trade or other publications (except by reason of
the Employee's breach of his obligations hereunder) and (ii) information which
the Employee is required to disclose by law or by a governmental entity or by an
order of a court of competent jurisdiction or pursuant to a subpoena from such a
court or agency. If the Employee is required by law or a court order to disclose
such information, he shall notify the Company of such requirement and provide
the Company an opportunity to contest such law or court order.

            (b) The Employee acknowledges that the services to be rendered by
him are of a special, unique and extraordinary character and, in connection with
such services, he will have access to confidential information vital to the
Company's business. By reason of this, the Employee consents and agrees that if
he violates any of the provisions of this Agreement with respect to
confidentiality, the Company would sustain irreparable harm and, therefore, in
addition to any other remedies which the Company may have under this Agreement
or otherwise, the Company shall be entitled to apply to any court of competent
jurisdiction for an injunction restraining the Employee from committing or
continuing any such violation of this Agreement, and the Employee shall not
object to any such application.

      10. Representation, Warranty and Covenant of the Employee. The Employee
represents, warrants and covenants to the Company that he is not and will not
during the Term become a party to any agreement, contract or understanding,
whether employment or otherwise, which would in any way restrict or prohibit him
from undertaking or performing his employment in accordance with the terms and
conditions of this Agreement.

      11. Representation and Warranty of the Company. The Company represents and
warrants that this Agreement constitutes a valid and legally binding obligation
of the Company, enforceable in accordance with the terms herein set forth,
except to the extent that the 


                                      -5-

enforceability of this Agreement may be affected by bankruptcy, insolvency,
reorganization, moratorium, or similar laws affecting creditors' rights and
remedies generally and subject, as to enforceability, to general principles of
equity, including principles of commercial reasonableness, good faith and fair
dealing (regardless of whether enforcement is sought in a proceeding at law or
equity).

      12. Deductions and Withholding. The Employee agrees that the Company shall
withhold from any and all payments required to be made to the Employee pursuant
to this Agreement, all federal, state, local and/or other taxes which the
Company determines are required to be withheld in accordance with applicable
statutes and/or regulations from time to time in effect.

      13. Entire Agreement. This Agreement, together with the other agreements
specifically referred to herein, sets forth the entire agreement and
understanding of the parties, and cancels and supersedes any and all prior
agreements and understandings (whether written or oral) between the parties
hereto, with respect to the employment of the Employee by the Company, and no
statement, representation, warranty or covenant has been made by either party
with respect thereto except as expressly set forth herein.

      14. Notices. All notices, requests, demands and other communications
hereunder shall be in writing and shall be delivered personally or sent by
registered or certified mail, return receipt requested, to the other party
hereto at his or its address as set forth at the beginning of this Agreement.
Either party may change the address to which notices, requests, demands and
other communications hereunder shall be sent by sending written notice of such
change of address to the other party.

      15. Assignability, Binding Effect and Survival. This Agreement shall inure
to the benefit of and shall be binding upon the heirs, executors,
administrators, successors and legal representatives of the Employee, and shall
inure to the benefit of and be binding upon the Company and its successors and
assigns. Notwithstanding the foregoing, the obligations of the Employee may not
be delegated and, except as expressly provided in Paragraph 7 hereof relating to
the designation of beneficiaries, the Employee may not assign, transfer, pledge,
encumber, hypothecate or otherwise dispose of this Agreement, or any of his
rights hereunder, and any such attempted delegation or disposition shall be null
and void and without effect. The provisions of Paragraphs 6, 7, 8, 9, 21 and 22
hereof shall survive termination of this Agreement.

      16. Amendment. This Agreement shall not be altered, modified, amended or
terminated except by written instrument signed by each of the parties hereto.

            (b) During the Additional Consulting Period, if the Company has

without the prior written consent of the Company, provide consultation services
or otherwise provide services to (whether as an employee or a consultant, with
or without pay), own, manage, operate, join, control, participate in, or be
connected with (as a stockholder, partner, or otherwise), any business,
individual, partner, firm, corporation, or other entity that is then a
competitor of the Company, including any entity engaged in the business of
providing vehicle emissions testing services or services directly related
thereto that comprise a material portion of the Company's business or any other
business that is definitely planned by or that is under development by the
Company or any of its affiliates during the Employee's employment (if Employee
is currently employed) or at the time of the Employee's date of termination
(each such competitor a "Competitor of the Company"); provided, however, that
the "beneficial ownership" by the Employee, either individually or as a member
of a "group" (as such terms are used in Section 13(d) of the Securities Exchange
Act of 1934 (the "Exchange Act") and Regulation 13D under the Exchange Act) of
not more than five percent (5%) of the voting stock of any publicly held
corporation shall not alone constitute a violation of this Agreement.

      It is further expressly agreed that the Company will or would suffer
irreparable injury if the Employee were to compete with the Company or any
subsidiary or affiliate of the Company in violation of this Agreement and that
the Company would by reason of such competition be entitled to injunctive relief
in a court of appropriate jurisdiction, and the Employee further consents and
stipulates to the entry of such injunctive relief in such a court prohibiting
the Employee from competing with the Company or any subsidiary or affiliates of
the Company in violation of this Agreement.

      IN WITNESS WHEREOF, the parties hereto set their hands as of the day and
year first above written.

(other than to the Company or a wholly owned Subsidiary of the Company), whether
direct or indirect, of all or substantially all of the assets of the Company, on

Directors of the Company (together with any new directors whose election by such
Board or whose nomination for election by the shareholders of the Company was
approved by a vote of a majority of the directors then still in the office who
were either directors at the beginning of such period or whose election or
nomination for election was previously so approved), cease for any reason to
constitute a majority of the Board of Directors of the Company then in office.

      For purposes of this definition, (i) the terms "person" and "group" shall

person shall be deemed to have "beneficial ownership" of all shares that any
such person has the right to acquire, whether such right is exercisable
immediately or only after the passage of time or upon the occurrence of certain
events.

      "Voting Stock" means the Capital Stock of the Company having generally the
right to vote in the election for a majority of the directors of the Company.

of the initial underwritten public offering by the Company of 3,400,000 shares
