                             EMPLOYMENT AGREEMENT

This Employment Agreement ("Agreement"), entered into as of the 27/th/ day of
October, 2000, between ATG Inc ("the Company") and Vik Mani ("Prospective
Employee") and collectively as "the Parties," is amended and agreed to by both
parties as of the _8th____ day of February, 2001.  This amended Agreement
supersedes the previous version of the Agreement; and the terms and conditions
contained herein shall govern the employment relationship between the Parties.
In consideration of the foregoing and the mutual promises and covenants
contained herein and other good and valuable consideration, the Company hereby
employs Prospective Employee as its Chief Operating Officer, and Prospective
Employee hereby accepts such employment.

1.   The term of the employment is for thirty-six (36) months effective the date
     of joining of the Company by Prospective Employee. ATG will announce
     Prospective Employee as its new Chief Operating Officer (COO) of the
     Company on a date mutually agreed upon. Prospective Employee shall start
     his employment, on a date mutually agreed upon between the Chief Executive
     Officer (CEO) of the Company and Prospective employee, which shall be soon
     after the Company announces Prospective Employee as its Chief Operating
     Officer. Prospective Employee is not employed "at-will", but is employed
     under the terms and conditions set forth in this Agreement.

2.   Prospective Employee will report at all times to the CEO of the Company.
     The following officers and department heads shall report to Prospective
     Employee: All operations personnel and business development personnel,
     except Fred Feizollahi.  As COO of ATG, Prospective Employee's duties and
     responsibilities will be to manage the Company's marketing, sales and
     operations. Provided, however, that the Engineering Department (headed by
     Fred Feizollahi) is outside of the scope of the COO's responsibilities. The
     COO reports directly to the CEO. The COO will have no responsibility for
     the financial management of the Company and is not authorized to sign
     Company checks or decide to whom such checks will or will not be written..
     The Finance, Accounting and Comptroller organizations report directly to
     the Chief Financial Officer (CFO), who reports directly to the CEO; and
     neither these organizations nor the CFO report to or are within the control
     of the COO or the Operations organization. The COO is not required or
     permitted to be involved in the collection, accounting or payment of taxes
     or other indebtedness on behalf of the Company.

3.   The Company shall pay a signing bonus ("Signing Bonus") of $560,000.00,
     hereby receipted for by Prospective Employee, and received by the
     Prospective Employee in two payments on October 5, 2000 ($307,500) and
     October 20, 2000 ($252,500) prior to Prospective Employee giving notice to
     his present employer of the intent to resign his employment. The Signing
     Bonus is paid to

                                       1
<PAGE>

     the Prospective Employee in consideration of the fact that the Prospective
     Employee is agreeing to resign his current employment as Senior Vice
     President with his current employer, CH2M Hill, a premier company of world
     standing in the industry and robust financial condition. By giving up his
     employment with CH2M Hill, the Prospective Employee is sacrificing in
     excess of one million dollars ($1,000,000.00) in annual bonuses, long-term
     incentive compensation, stock options, retirement plans, ESOP contributions
     and company stock appreciation. ATG considers the services of the
     Prospective Employee critical to its credibility in the industry because of
     the proven credentials, skills and experience of the Prospective Employee
     and is, therefore, willing to make this up-front investment as a Signing
     Bonus for the Prospective Employee as inducement for Prospective Employee
     to resign his current employment and join ATG, a much smaller company with
     potential for growth but facing much greater challenges and uncertainties.
     The Signing Bonus shall be irrevocable and non-refundable to the Company
     and is for the inducement to the Prospective Employee to execute this
     Agreement and leave his current, senior level employment with a more
     assured financial future and guaranteed employee benefits. Upon the
     execution of this Agreement and giving notice to his current employer, the
     said Signing Bonus shall be deemed fully earned. Prospective Employee shall
     be responsible for all taxes associated with the signing bonus, i.e.
     federal and state withholding for income taxes, social security, and
     Medicare.

4.   In addition to the Signing Bonus described in Section 3., the Company shall
     pay Prospective Employee a salary of $325,000, in the first twelve (12)
     months of employment payable in accordance with Company current payroll
     practices as other employees are scheduled for their payment of employment
     compensation. Total first twelve (12) months' compensation, excluding the
     Signing Bonus and stock options as hereinafter set forth, is $325,000
     gross.

5.   The Company shall pay to Prospective Employee in the second twelve (12)
     month period of employment, a salary of $300,000.  Further, Company shall
     pay Prospective Employee a performance cash bonus of $50,000.00 based on
     predetermined performance goal as set forth below. The total compensation
     is $350,000 in the second twelve (12) month time period if performance goal
     is met, excluding stock options as hereinafter set forth.  The performance
     goal is defined as the Company obtaining a minimum of $15 million ("New
     Business Goal") of new DOE business (contracted capacity) from INEEL,
     Hanford, Rocky Flats or any other DOE contracts within twenty-four (24)
     months from commencement of the employment.  Once the $15 million minimum
     New Business Goal requirement is met, the performance cash bonus will be
     earned based on $10,000 per million dollars of new business up to a maximum
     of $50,000.  Such performance bonus earned by the Prospective Employee
     shall be paid to the Prospective Employee at six month intervals commencing
     the date

                                       2
<PAGE>

     of achievement of the new business goal, but no later than 30 days after
     earning the maximum second twelve (12) month employment period performance
     bonus as stated above. In the event Prospective Employee is terminated by
     the Company, resigns for Good Reason, as hereinafter defined, or due to
     Change of Control, as hereinafter defined, or dies or becomes disabled
     during the second twelve (12) month period, such performance bonus will be
     computed and paid on the same basis as if he were still employed with the
     Company for such period.

6.   The Company shall pay to Prospective Employee in the third twelve (12)
     month  period of employment a salary of $300,000 , plus a cash bonus up to
     the amount of $50,000 based on the performance goal to be determined by
     both Parties.  Such goal will not be less than $20 million of DOE New
     Business ($20 million of DOE new business contracted capacity) from
     Hanford, Rocky Flats, INEEL or any other DOE contracts, however, alternate
     sources of "New Business" may be agreed upon between the Company and the
     Prospective Employee as the basis for setting the performance goal (New
     Business) stated above.  Such bonus shall be paid to Prospective Employee
     pro-rated at 6 month intervals commencing the date of achievement of the
     performance goal, but no later than thirty (30) days after earning the
     bonus set forth above.  In the event Prospective Employee is terminated by
     the Company, resigns for Good Reason, as hereinafter defined, or due to
     Change of Control, as hereinafter defined, or dies or becomes disabled
     during the third twelve (12) month  period, such bonus will be computed and
     paid on the same basis as if he were still employed with the Company for
     such period.  During the third twelve (12) month period of employment only,
     the Prospective Employee will be paid salary at the annual salary rate of
     $300,000 only after the performance goal as agreed upon between the Company
     and the Prospective Employee as stated above is achieved and the actual
     business delivered during the first 24 months of employment is at least $10
     million.  During the third twelve (12) month period of employment only,
     until such a time when the performance goal is achieved, the Prospective
     Employee will be paid salary at the reduced annual rate of  $200,000.  In
     the event the performance goal for the third twelve (12) month  period is
     not mutually agreed to, then it shall be as set forth above, which is
     defined as the Company obtaining a minimum of $20 million ("New Business
     Goal") of new DOE business (contracted capacity) from INEEL, Hanford, Rocky
     Flats or any other DOE contracts within 24 months from commencement of the
     employment.

7.   In addition to the Company's New Business Goals, as the Chief Operating
     Officer, Prospective Employee understands that other overall measures of
     Company's performance, such as profitability, cost cutting measures, health
     and safety, effective and efficient operation, new market and product
     development, will also be within Prospective Employee's executive
     responsibility.  However, the standard for Performance Bonus eligibility
     shall be the New Business Goals.

                                       3
<PAGE>

     Because of such responsibilities of Prospective Employee, the Company
     agrees to provide Prospective Employee with a sufficient operations budget
     assistance and support to allow the accomplishment of the New Business
     Goals, such as reasonable travel and entertainment expenses, cell phone,
     computer, etc and other customary Business Development expenses, as well as
     to assist Prospective Employee in his overall responsibilities. Prospective
     Employee is authorized to incur expenses in the performance of his duties.
     The Company shall reimburse Prospective Employee for all such expenses ten
     days after submitting the expenses or at the next pay period, whichever is
     sooner. The Company recognizes that Prospective Employee's ability to
     assist the Company in achieving its performance goals, including New
     Business Goals, may be affected by matters beyond Prospective Employee's
     control and/or prior knowledge, such as Company's financial condition,
     prior regulatory violations or other prior conflicts with clients.
     Therefore, Prospective Employee's failure to meet the New Business Goals or
     otherwise meet Company's anticipated levels of performance shall not
     constitute a basis to deny Prospective Employee payment of performance
     bonuses or terminate Prospective Employee's employment for Cause (as
     defined below) to the extent caused by matters beyond Prospective
     Employee's control and/or prior knowledge.

8.   In the event the  Prospective  Employee resigns from the company due to no
     breach by the Company of this agreement before expiration of the (36)
     months term of this agreement,  Prospective Employee's Employment will end,
     without further obligation or liability to the Company, provided, however,
     the Prospective Employee will make himself available to ATG upon request on
     an exclusive consulting basis at the rate of $2000/day for a minium period
     of up to 180 days following his resignation in order to assure an orderly
     transition.  The foregoing shall constitute Company's exclusive remedy in
     the event that Prospective Employee terminates his employment prior to the
     expiration of the (36) months terms of this agreement due to no breach of
     this Agreement by the Company.  Company expressly waives the right to seek
     other remedies , including but not limited to specific performance, or to
     claim damages, whether arising in contract, tort, otherwise including
     (negligence and strict liability) in connection with Prospective Employee's
     resignation of his employment. In the event the Prospective Employee
     resigns during the term of this Agreement due to breach of this Agreement
     by the Company, the Company filing  Bankruptcy  in any form, or for  Good
     Reason (hereinafter defined), then the Company shall pay the Prospective
     Employee an amount equal to one twelve (12) month period salary for the
     twelve (12) month period of such resignation earned but not paid
     performance bonuses, . and the relocation costs set forth in Section 18
     hereof.  All payments will be effected in a single lump sum payment within
     two weeks of the effective date of Prospective Employee's resignation.

                                       4

     Further, all the stock options granted shall be deemed fully earned and
     vested with the time period to exercise all stock options extended by one
     year and the Company shall be responsible for the continuation of medical
     benefits at Company's expense for a period of twelve (12) months.  It is
     the intent of the Prospective Employee to remain on the Company's Payroll
     and help the Company through any restructuring activities, provided
     however, there would be no change in compensation  and there will be no
     change of  the CEO  and/or the Executive Vice President.

     B.   In the event Prospective Employee is terminated by the Company for any
     reason whatsoever, including disability, and other than for Cause ("Cause"
     as defined below) prior to the end of the thirty-six (36) month  term, the
     Company shall pay the Prospective Employee a severance salary equal to one
     twelve (12) month period salary for the twelve (12) month  period such
     termination occurs, all the performance cash bonuses earned but not paid to
     Prospective Employee until then,  and the relocation costs as set forth in
     Section 18 hereof. All payments will be effected in a single lump sum
     payment within two weeks of the effective date of Prospective Employee's

     earned and vested with the time period to exercise the stock options
     extended by one year .  Additionally, the Company shall be responsible for
