Mr. Greg Cronin

Marietta, GA  30062

Dear Greg:

On behalf of the Board of Directors, we are pleased to offer you the position
of Chief Executive Officer and member of the Board of Directors of Arctic
Inc., the new corporation ("the Company") being formed from Frontec AMT. In
making this offer, we are expressing our enthusiastic support for your
leadership skills and abilities. You bring a skill set to this Company that
is essential to achieving our goals, both short and long term. In addition,
we expect that your base of experiences and contacts will enable you to
significantly impact and influence the strategic direction of the
organization. The purpose of this letter is to detail the terms of your
employment.

-        JOB TITLE:  Chief Executive Officer

-        STARTING DATE:  As soon as possible, but no later than Thursday,
         March 11, 1999

-        SALARY:  $200,000 per year, payable monthly, according to the
         compensation plan of the Company

-        BONUS:  In addition to your base compensation, you will participate
         in an annual incentive bonus program determined by the Board of
         Directors under which you will be entitled to earn incentive
         compensation of up to $150,000.  This incentive portion of your
         compensation will be based upon the satisfaction of certain
         performance goals and for the first twelve months will be divided
         into two separate bonuses of $75,000, the first of which will be
         after the completion of your first six months and the second after
         the completion of your first full year.  The performance objectives
         will be determined by the Company's Board of Directors, and will
         concern such matters as revenue, profitability/cash control,
         executive hiring and other specific management goals to be mutually
         agreed upon.  For the first full year you will receive a minimum
         bonus payment of at least $75,000.

-        STOCK:  You will be given the opportunity to purchase 2,575,275
         shares (representing approximately 5% of the fully diluted
         outstanding shares of the Company) in the form of stock options or
         restricted stock available for purchase. If you choose to purchase
         the stock, the Company will loan you the money at a market rate of
         interest.  The exercise price of the options or the purchase price
         of the restricted stock will be the

         fair market price of the common shares as determined by the Board of
         Directors, which is $0.25 per share. These restricted shares or
         options will be subject to a four (4) year vesting schedule.  You
         will vest 321,905 shares immediately upon beginning employment.
         Starting on December 31, 1999, you will begin vesting 160,955 shares
         per quarter for the next 14 quarters, subject to your continued
         employment. You are eligible to be granted additional stock either
         in the form of restricted stock or stock options at some time in the
         future, at the sole discretion of the Board of Directors, assuming
         outstanding performance on your part.

         IN THE EVENT YOU ARE INVOLUNTARILY TERMINATED BY THE COMPANY WITHOUT
         "CAUSE" (AS DEFINED BELOW) OR IF A "CHANGE OF CONTROL" (AS DEFINED
         BELOW) OCCURS, IN EITHER CASE PRIOR TO SIX (6) MONTHS AFTER THE
         COMMENCEMENT OF YOUR EMPLOYMENT WITH THE COMPANY, ONE-HALF (1/2) OF
         YOUR RESTRICTED STOCK OR OPTIONS WILL IMMEDIATElY BECOME VESTED. IF
         AT ANY TIME FOLLOWING THE SIX MONTH ANNIVERSARY OF YOUR EMPLOYMENT A
         "CHANGE OF CONTROL" OCCURS WHERE YOU ARE NOT OFFERED THE OPPORTUNITY
         TO REMAIN EMPLOYED AS THE CEO, GENERAL MANAGER OF THE ARCTIC
         DIVISION OR A COMPARABLE POSITION, THE VESTING SCHEDULE FOR YOUR
         SHARES WILL BE ACCELERATED SO THAT 1/2 OF YOUR NON-VESTED SHARES
         WOULD VEST IMMEDIATELY UPON "CHANGE OF CONTROL". IN ALL OTHER CASES
         YOUR SHARES WILL VEST AS OUTLINED IN THE PREVIOUS PARAGRAPH.

         For the purpose of this letter agreement, "Change of Control" shall
         mean the occurrence of the following event: the stockholders of the
         Company approve a merger or consolidation of the Company with any
         other corporation, other than a merger or consolidation which would
         result in the voting securities of the Company outstanding
         immediately prior thereto continuing to represent (either by
         remaining outstanding or by being converted into voting securities
         of the surviving entity) at least 50% of the total voting power
         represented by the voting securities of the Company or such
         surviving entity outstanding immediately after such merger or
         consolidation, or the stockholders of the Company approve a plan of
         complete liquidation of the Company or an agreement for the sale or
         disposition by the Company of all or substantially all the Company's
         assets.

-        BENEFITS: The Company will provide you and your family major
         medical, dental, 401(k), etc. benefits as commonly provided to all
         Company employees, and your rights under such benefit plans will be
         determined under the provisions of such plans. You will be subject
         to the Company's standard vacation and sick leave policies, and if
         for any reason you need additional time, it will be negotiated and
         subject to approval by the Company's Board of Directors.

-        CONFIDENTIAL INFORMATION: As an employee of the Company, you will
         have access to confidential information. Moreover, you may, during
         the course of your employment, develop certain information or
         inventions that will be the property of the Company.

         To protect the interest of the Company, we will ask that you sign
         the Company's standard Nondisclosure and Developments Agreement and
         non-competition agreement as conditions of your employment. We wish
         to impress upon you that we do not wish you to bring with you any
         confidential or proprietary material of any former employer or to
         violate any other obligation to your former employers.

-        EMPLOYMENT AT WILL: Your employment with the Company is "at will",
         meaning you are not obligated to remain employed at the Company for
         any specific period of time.  Likewise, the Company is not obligated
         to employ you for any specific period.  In the event the Company
         terminates your employment without "cause," as defined below, or
         your employment is terminated as a result of disability as
         determined by the Board of Directors, then upon execution of a
         release you will be entitled to severance pay consisting of
         continuation of your then current base salary (excluding bonus),
         payable in accordance to company practices, as well as paid medical
         benefits, for a period of nine (9) months.  Stock options and
         restricted stock will not continue to vest during this nine-month
         severance period following your termination.   If you accept any
         other employment during this nine-month period then your base salary
         and medical benefits will cease at that time.

         For purposes of this severance provision, "cause" means a
         determination by the Board of Directors that shall be conclusive
         that you have (a) engaged in acts in violation of law or in other
         conduct which is unbecoming of a CEO of a major company or is
         otherwise detrimental to the Company; (b) breached your
         Nondisclosure and Developments Agreement, your fiduciary duty to the
         Company, or your duties of loyalty and/or care to the Company; or
         (c) disobeyed the good faith, lawful policies or instructions of the
         Board of Directors. Your employment shall also be deemed to be
         terminated without "cause" if, within one week after you are
         informed that the Company plans to relocate outside Atlanta or
         change your job responsibilities so that you are no longer the
         Company's CEO, you notify the Board of Directors that you intend to
         resign and thereafter the Company follows through with such
         relocation or change and you resign within one week thereafter.

-        RESTRICTIVE COVENANTS: You agree that, for a period of one year
         following any termination of your employment, you will not directly
         or indirectly solicit the services of any Company employee for
         another activity, or otherwise induce or attempt to induce such
         employee to leave the employment of the Company.

-        OTHER: The Company will make such deductions, withholdings, and
         other payments from all sums payable to you that you request or that
         are required by law for taxes and other charges.  This agreement may
         not be changed or modified except by agreement in writing, signed by
         you and an appropriate designee of the Board of Directors.  You
         hereby acknowledge that you are not a party to any agreement that in
         any way

         prohibits or imposes any restriction on your employment with the
         Company, and your acceptance hereof will not breach any agreement to
         which you are a party.  You will provide the Company with copies of
         any relevant employment-related agreements with your current
         employer, such as non-compete agreements, etc.  This agreement shall
         be governed, construed and enforced in accordance with the laws of
         Georgia without regard to principles of conflict or law.  Should any
         provision of this agreement, or portion thereof, be found invalid
         and unenforceable, the remaining provisions shall continue in force
         and effect.

-        TERMS OF OFFER: This offer will remain open until the end of
         business on Friday, March 5, 1999. When you do accept, and all of us
         sincerely hope you will, please sign the enclosed copy of this
         letter and return it via fax to me with a copy to Scott Tobin, with
         the original to follow.

Greg, we are excited to have you join us and are enthused at the prospect of
tackling a very promising future together. We look forward to a long and
mutually rewarding relationship.

Sincerely yours,

Bengt Wallentin
Chairman
