Item 11.  	Executive Compensation

     Cash Compensation

The following table sets forth information concerning the compensation paid 
by the Company and its subsidiaries during the Company's fiscal years ended 
December 31, 1996, 1995 and 1994 to the chief executive officers of the 
Company and Incat, its sole operating subsidiary.  No employees of the 
Company earned compensation in excess of $100,000 in 1996.  Because 
the Company's former President, Craig E. Bowman, who resigned in December 
1996, divided his time between Incat and Piping, optional supplemental 
information regarding the compensation paid to the individuals who served as 
the most senior full time officers of Incat for the years ended December 31, 
1996, 1995 and 1994 is provided.

(1)  Mr. Bell receives no compensation from the Company or its subsidiaries.  
He was compensated through a management agreement with IST which expired 
on December 31, 1996.  IST receives management fees from Incat and other 
operating subsidiaries.   The monthly management fee paid by Incat to IST 
was $8,000 until October 1995 when Incat's monthly management fee to IST 
increased from $8,000 to $12,000.   Effective January 1, 1997, Incat's 
management fee became $14,000.

(2)Pursuant to Incat's agreements with FINOVA Capital Corporation ("FINOVA"), 
Incat carried $500,000 of key man life insurance on Mr. Bowman, the proceeds 
of which were assigned to FINOVA.  In 1995,   FINOVA released the 
Company from the requirement and Piping maintained the policy until Mr.
Bowman resigned from Piping in February 1997.

(3)The supplemental information is not required to be disclosed pursuant to 
this item because  none of the individuals serve as  Chief Executive Officer of
Incat.  It is provided supplementally because these individuals were the most
senior full time officers of Incat for the periods disclosed.

(4)  Each of Mr. Kouri and Mr. Stroup received a vehicle allowance in 
each of the periods shown.  In addition, Mr. Kouri and Mr. Stroup were 
included in Incat's  health insurance plan on the same terms and  conditions 
as other employees.   Mr. Kouri resigned his position with the Company in 
January 1997.

</TABLE>

Since July 1, 1993, Mr. Brehmer has been entitled to receive $500 per month 
for services as an officer and director of the Company.   These amounts are 
accrued by AES as there are restrictions on Incat's ability to provide funds 
to AES.      

There are no employment agreements between AES or AEC and their
respective officers and directors.  The officers and directors of these 
corporations dedicate only such time to these corporations as is necessary 
for the conduct of their businesses.   During the year ended December 31, 
1996, the officers and directors of  AES and AEC devoted less than 10% of 
their time to its affairs.  


During 1993, Mr. Bowman became an employee both of Incat and of 
Piping.   Incat paid Mr. Bowman, who devoted approximately 25% of his 
time to the business of  Incat, a salary at an annual rate of $36,300.  
Mr. Bowman did not receive an automobile allowance from Incat and was 
not covered by the Company's medical plan.  He participated in the 
Company's 401(k) Plan, pursuant to which he received  a contribution 
from Incat of $810 for the year ended December 31, 1994.  No contributions 
were made to the 401(k) Plan by Incat  for the years ended December 31, 1995 
and 1996.

Tables for (a) Aggregated Option/Stock Appreciation Rights (SAR) Exercises
in Last Fiscal Year;  (b) Fiscal Year End SAR Values, (c) Long-term Incentive
Plan (LTIP) Awards, and (d) Defined Benefit Pension Plans are omitted as
no information is reportable thereunder for any persons listed in the Summary
Compensation Table.   No stock options have been granted by the Company
since 1991.  See "1988 Stock Option Plan" set forth below on this item.

In January 1995, the five Board of Directors voted to reduce the exercise price 
of all outstanding option from $.015 to $.008.   No other terms of the options 
changed.  The Board of Directors had determined the exercise price of $.015
established in 1991 exceeded the trading range for the Company's common
stock by a very significant amount.  Due to the large disparity between the 
trading price of the Company's stock and the exercise price the options were
neither providing incentives to employees nor serving as an inducement to
these employees to remain with the Company.  The per share market price at 
the time of the reduction was less than the exercise price as readjusted.

directors of the Company.  Mr. Bell and Mr. Schmitt receive no direct
compensation for their serves as officers and directors of AES and or its
subsidiaries.  Mr. Brehmer is entitled to receive $500 per month for serving as 
a director and officer of AES.  The salary of  Mr. Kearns is determined by the 
entire board of directors of Incat, consisting of Messrs. Schmitt, Austin and 
Kearns.  Mr. Austin receives $1,500 a month in compensation for serving as 
a part time employee and officer at Incat.  Mr. Kearns is compensated at a rate 
of $85,000 per annum.    Both Mr. Austin and Mr. Kearns receive an automobile 
allowance and may participate in benefit plans on the same basis as all

committee of IST.  See Item 13.

     Board Compensation Committee Report on Executive Compensation

As indicated above, none of AES, AEC or Incat has a compensation committee 
and all such functions are performed by their respective boards of directors.
The directors and officers of AES and AEC received no direct compensation for 
serving as such in 1996 except Mr. Brehmer.   The Board of Directors of AES 
determined that  commencing July 1, 1993 Mr. Brehmer would be paid $500 
per month for services to the Company in capacity as officer and director.  
The monthly fee was determined on the basis of the amount of time he spends 
on the business of the Company.  The amount has been accrued as there are 
restrictions on Incat's ability to provide funds to AES.  Mr. Bell and Mr. 
Schmitt, who receive no direct compensation for serving as directors and 
officers of AES and/or its subsidiares, are compensated for their serves to 
IST and its subsidiaries through arrangements with IST, to which Incat paid 
IST a monthly management fee of $12,000.   Effective January 1, 1997, Incat's
monthly management fee to IST increased from $12,000 to $14,000.  See Item 13.

None of the directors of Incat receive any direct compensation from Incat
for serving as such.   The salaries of Mr. Austin and Mr. Kearns for their 
services as officers and employees are determined by the Board of Directors 
of Incat, which considers a variety of factors in an effort to accomplish 
several goals.  These goals are to provide long and short term financial 
incentives based on performance for executives on whom the success of 
Incat may depend.  Base salary is determined in part by the skills and 
experience of the individual, the amount of time the individual devotes to 
the Company and the amounts which the individual could command in the 
market place.  

                        Performance Table

The following table compares the yearly percentage change in the book value 
per share and in the price per share of the Company's common stock in the years
ended December 31, 1996, 1995 and 1994, nine months ended December 31, 1993 
and the fiscal year ended March 31, 1993  to the changes for the same period 
in the CRSP Total Return Index for (i) the U.S. NASDAQ Stock Market and (ii) 
the NASDAQ Truck/Transportation Index, which is the published NASDAQ sub 
index most closely related to the Company's business.    

The table is required to be included in this Annual Report under rules and 
regulations promulgated by the Securities and Exchange Commission (the "SEC")
pursuant to the Securities Exchange Act of 1934 (1934 Act) which require a 
comparison between market performance in general and the market price of 
the shares of the Company's common stock.  Because trading in the Company's 
common stock is sporadic and prices for the stock are highly volatile and 
based on interdealer quotations, without retail mark-up, mark-down or 
commission, and are not necessarily representative of actual transactions, 
the prices for the shares of the Company's common stock used in the 
preparation of the table are based on the average of the high and low bid for 
the last quarter of each of the applicable periods.  Also because of the 
sporadic nature of trading in shares of the Company's common stock and other 
factors, such as the limited number of market makers, the Company has 
included a comparison based on book value as the Company believes that this 
comparison may provide other information about the Company's performance.

The returns shown for the NASDAQ indices assume the reinvestment of all 
quarterly dividends at the average of the closing stock prices at the 
beginning and end of the quarter as required by SEC rules.  There were no 
dividends paid on shares of the Company's common stock.  The book value of a 
share of the Company's common stock was computed on the basis of the 
Company's Common and Other Stockholders' Equity, after restatement to exclude
the Series A Preferred Stock for all years except December 31, 1996 in which
$94,000 was classified as equity and after also excluding the liquidation 
preference attributable to the shares of the Company's Series A and B Preferred
Stock, which was  $200,000 at March 31, 1993 and December 31, 1993, 1994, and 
1995 and $295,000 at December 31, 1996.

performance for a variety of reasons, including but not limited to, the 
sporadic market for the shares.

    	1988 Stock Option Plan.  
The Company adopted the 1988 Stock Option Plan on October 31, 1988 
(the "Stock Option Plan").  The Stock Option Plan is designed to provide 
incentives for certain key employees of the Company and its subsidiaries by 
providing up to 25,000,000 shares of the Company's common stock issuable 
pursuant to grants.  The Stock Option Plan allows for the grant of both 
incentive stock options and non-qualified stock options.  Incentive stock 
options may be granted solely to key employees, whereas non-qualified stock
options may be granted to any employee.  The Stock Option Plan is administered
by an option committee composed of the Board of Directors of the Company or 
at least three members of the Board; provided, however, that with respect to 
options to employees who are also directors of the Company, the Stock Option 
Plan will be administered by a committee selected by the Board which shall 
consist of two or more Directors, each of whom shall not have received 
options under the Stock Option Plan or any other discretionary stock plan of 
the Company within one year prior to his appointment to the Committee.  The
option committee is authorized, within the limits of the Stock Option Plan,
to determine the individuals to whom, and the time or times at which, options 
will be granted, the number of shares to be subject to each grant, and the 
applicable restriction period.  In addition, the option committee may 
determine the  purchase price for the shares subject to the option and 
specify such other terms and provisions of any grants of options under the 
Stock Option Plan as it deems necessary or advisable.  The term of any option
granted under the Stock Option Plan may not be greater than ten years and no 
option may be exercised for a six month period following the date of its 
grant.  The option committee may determine whether an option will be 
exercisable in installments and, if it so decides, the number of installments
and the percentage of the options exercisable at each installment date.  The 
Company granted options with respect to an aggregate of 18,261,013 shares 
during the fiscal year ended March 31, 1991.  There have been no subsequent 
grants of options pursuant to the Stock Option Plan.

All the options granted in fiscal 1991 were granted at a price of $.015 per 
share and become exercisable as to one-fifth of the options on a cumulative 
basis on each successive yearly anniversary date of the date of grant.  The 
options expire seven years from the date of grant.  In 1995, the Board of 
Directors changed the exercise price of all options from $.015 to $.008.
All other option terms remain unchanged.   At December 31, 1996, 
7,028,594 options had been forfeited by persons whose employment 
terminated.   None of  the options granted by the Company were granted 
to officers or directors of  AES, AEC or Incat  with the exception of options 
with respect to 1,710,377 and 1,979,350  shares granted to Mr. Kearns 
and Mr. Austin, respectively, who hold the positions indicated in Item 10.  

Item 12.	  Security Ownership of Certain Beneficial Owners and Management; 
           Changes in Control.

Set forth in the following table is information as of March 31, 1997 with 
respect to the beneficial shareholdings of all directors, individually, all 
officers and directors of AES as a group, and beneficial owners of more 
than five percent of  AES's common and preferred stock.  In addition 
to its common stock, the Company has Series A Preferred Shares and 
Series B Preferred Shares, all of which have a par value of $.0001 per 
share and are owned by IST.   In July 1996, the Statement of Change 
in Beneficial ownership of  Securities on Form 4 of  IST  which reported
one transaction was filed late, but within the month when due.

and in trust for Mr. Brehmer. Also includes 100,000 shares held in the name  
of AAA Accounting Services, Inc., of which Mr. Brehmer is the sole 
shareholder.  Mr. Brehmer is the secretary-treasurer, director and ten 
percent shareholder of International Marketing Visions, Inc. ("IMV"), a 
corporation which owns 1,031,262 shares of common stock of the Company.  Mr. 
Brehmer disclaims any beneficial ownership of 928,136 shares or 90 percent of
the common stock held by IMV.

(3)	Includes 328,199,280 shares of common stock and the Series A and B 
Preferred shares owned by IST.  Mr. Bell is a director and principal 
shareholder of IST and may, therefore, be deemed to be a beneficial owner of 
the shares owned by IST.  Includes 1,350,000 shares owned by Carylyn K. Bell,
Mr. Bell's wife and 5,000,000 shares owned by Mr. Bell directly.  Mr. Bell 
disclaims any beneficial ownership to 2,954,892 shares owned by his father.

(4)	Mr. Schmitt is an officer and director of IST, and may, therefore, be 
deemed to be a beneficial owner of the common and the Series A and B 
Preferred shares owned by IST.

 (5)	Does not include the shares of common stock into which the Series A and B
Preferred Shares are convertible on a one-for-one basis.  Assuming conversion
of all the Series A and B Preferred Shares, IST would own an aggregate of 
368,521,499 shares or 64.4% of the 571,989,734 shares of common stock that 
would be issued and outstanding after the conversion.

</TABLE>

During 1993 and 1994 a wholly owned direct subsidiary of IST issued notes 
totaling $1,000,000, which notes were guaranteed by IST.  IST pledged 
299,053,596 shares of AES common stock and its shares of Series B Preferred 
Stock of AES as security for its guarantee.  The majority of the note holders
are individuals and entities controlled by persons who serve on the Board of 
Directors.   These individuals constitute a majority of the Board of Directors 
of IST.  The Bridge Notes, as amended on February 15, 1996, provided that 
(a) the principal amount of each Bridge Note was to be paid in three 
installments with the two installments of 25% of the original principal 
amount due and payable on February 15, 1996 and September 15, 1996, and the 
third and final installment of 50% of the original principal amount due and 
payable on January 10, 1997, and (b) interest on the principal balances 
outstanding from time to time was to be paid in arrears on April 15, 1996, 
July 15, 1996, October 15, 1996 and January 10, 1997.  All of the interest 
payments were made when due.  The principal installments due on February 15, 
1996 in the aggregate amount of $250,000 also were paid in full.  Of the 
total $250,000 amount due on September 15, 1996, a total of $58,850 was paid,
as a result of which a total of $308,850 has been paid and a total of 
$691,150 remains to be paid.  The notes have been renegotiated so that 
remaining outstanding principal amount of $691,150 shall be payable in two 
principal installments of $172,787.50 each due on  September 30, 1997, 
December 31, 1997, and a final installment of $345,575 due March 15, 1998.  
Interest on the outstanding principal balances would continue to be due and 
payable on the 15th day of each of April, July, October and January of each 
year until the entire principal balances are paid in full.  In the event that
IST were to default on its obligations under its guarantee, the note holders 
could, pursuant to the Pledge Agreement, foreclose on the pledged shares.   
Also, in connection with the Bridge Notes, IST issued warrants to the note 
holders which may be exercised at the option of the note holders for either 
(a) approximately 13% of the common stock of IST or (b) 13% of the shares of 
AES common stock owned by IST, which is approximately 6% of AES issued and 
outstanding common stock. See Item 13;  Certain Relationships and Related 
Transactions.


Set forth in the following table is information as of March 31, 1997 with 
respect to the beneficial shareholdings of all directors, individually, and 
all officers and directors of AES as a group of the common stock, $.01 par 
value per share, of IST.    As of  March 31, 1997, there were 21,170,970 
shares of common stock and 4,821,000 shares of preferred stock of IST 
issued and outstanding.  Each share of IST's common stock has one vote.
The percentages shown in column (B) in the following table do not  include 
the voting rights of the holders of  IST's preferred stock or which the 
holders of certain warrants issued in conjunction with institutional debt and 
subordinated notes or stock options would have if they  exercised their 
warrants and options.  Each share of preferred stock has a number of votes 
based on the number of common shares into which it would be converted.
If the convertible preferred shares were converted into common stock, the 
number of common shares outstanding would be approximately 28,974,000.         
Accordingly, including the effect of the voting rights of  holders of 
preferred, the percentage of voting rights held by each individual indicated 
would be set forth in column (C).   Additionally, if all the outstanding 
warrants issued in conjunction with institutional debt and subordinated notes
and all outstanding stock options were exercised, the number of  IST common 
shares outstanding would be approximately 44,325,000.   However,  none
of the warrants or options have been exercised and their holders presently
have no voting rights.  The formulas regarding the computations of the 
number of shares into which the preferred stock are convertible and for 
which the warrants and stock options are exercisable are complex and 
interrelated.  Certain factors used in determining common stock equivalents 
continue to be the subject of negotiations.  Accordingly the foregoing 
numbers and percentage amounts in column (C) are estimates only 
and subject to change.  None of the persons listed in the table below 
owned any of the Preferred Stock, warrants or options of  IST.

Item 13.     	Certain Relationships and Related Transactions

From November 25, 1996 to January 17, 1997, the Company had a loan 
with Carylyn K. Bell in the amount of $425,000 secured by the Company's 
claims for federal tax refunds of  $458,000.  Interest was payable at a rate 
of 10.25% per annum.  AES paid a 2.5% loan fee.  Ms. Bell is a significant 
shareholder of the Company and the wife of J. Daniel Bell, the President and 
a director of the Company.  In addition, Ms. Bell is a principal shareholder 
of  IST.  IST provided an unsecured Guaranty of the loan.   The Company 
believes that the terms of the loan from Ms. Bell were commercially 
reasonable and at least as favorable as could have been obtained in an 
arm's length transaction.

In April 1990, AES borrowed $500,000 from IST.  The $500,000 amount loaned by
IST to the Company was borrowed by IST from FINOVA.  The Company had 
attempted to borrow the funds directly from FINOVA; however, FINOVA was
unwilling to make the loan.  The proceeds of the loan were paid by AES to AEC
as additional capital.  AEC then loaned the proceeds to Incat.  FINOVA 
required, pursuant to the provisions of its loan agreement with AEC, that 
Incat issue a note to AEC and grant a security interest in all its assets to 
AEC.   AEC assigned to FINOVA its interests in the promissory note made by 
Incat and in the collateral.   At December 31, 1996 and March 31, 1997,  the 
outstanding balances of both the IST and Incat notes were approximately 
$128,000 and $94,000, respectively.   On March 31, 1997, IST repaid the 
outstanding balance of its FINOVA loan concurrently with the refinancing by 
AEC of its term loan to FINOVA.   See Item 7; "Management's Discussion and 
Analysis of Financial Conditions and Results of Operations". 
 
The loan originally made in 1990 by IST to AES was evidenced by the 
convertible promissory note of AES and was converted into 61,538,550 shares 
of Series A Preferred Shares.   The Series A Preferred Shares pay cumulative 
cash dividends at the rate of $.0011368 per share per annum, payable in 12 
monthly installments of $.000094733 each, and have a liquidation preference 
of $.008133 per share. The cumulative amount paid with respect to the 
Series A Preferred stock since its issuance is $546,659 of which $372,552 has
been applied to the redemption of 45,807,503 Series A Preferred Shares.  As 
of December 31, 1996 and March 31, 1997,  15,731,047 and 11,656,910 Series A 
Preferred Shares were outstanding, respectively.  See Item 7; "Management's 
Discussion and Analysis of Financial Conditions and Results of Operations".

AES issued to IST a total of 24,591,170 shares of its Series B Preferred Shares 
for $200,000 in 1991 and 1992.  The Series B Preferred Shares pay an annual 
dividend of $.0011368 per share, payable quarterly, and have a liquidation 
preference of $.008133 per share.    As of December 31, 1996 the Company 
owed IST approximately $150,000 for cumulative and unpaid dividends with 
respect to the Series B Preferred Stock of which $94,000 was paid on March 31, 
1997.  See Item 7; "Management's Discussion and Analysis of Financial 
Conditions and Results of Operations".

The Company paid IST management fees of $12,000 per month in 1996.
Effective January 1, 1997, the Company `s monthly management fee is $14,000.  
Pursuant to the provisions of the FINOVA loan agreement, management fees 
paid and changes in amount of fees paid to IST require FINOVA's  approval 
if amounts exceed $15,000 a month.

Incat's casualty program is a combined lines incurred loss retrospective 
rating program consolidating coverage for IST's operating subsidiaries 
including Incat .  Coverages included in the combined lines are the Workers 
Compensation/Employees Liability, Auto Liability and General Liability.  
The program is a loss sensitive program.  Premium payments are based on the 
minimum pay-in calculation by the insurance company plus expected losses.  
Final premium calculations are made after the policy period by audit and retro
adjustment.  A pay-in allocation for each subsidiary is prepared by taking the 
rating basis provided by each IST subsidiary and calculating the pay-in on a 
percentage basis from the information provided by each subsidiary.  Management
believes that coverage purchased on a consolidated basis provides 
opportunities for the participating entities to decrease costs and increase 
coverage options.  In addition, the increased buying power enables the 
participating entities to qualify for types of insurance plans that would not
otherwise be available.   See items 1 and 2; "Business and Properties".

The Company retains Corporate Stock Transfer, Inc.  ("CST") as its
transfer agent.  Carylyn K. Bell, a principal shareholder of IST and the 
spouse of  J. Daniel Bell, is the President and a principal shareholder of 
CST.  Alfred Brehmer, a director and officer of the Company, is an officer 
and director of CST.  The amounts paid by the Company to CST are not 
significant and are believed by management to be commercially reasonable.  

For periods during which Mr. Bowman or Mr. Austin served as employees of 
both Incat and Piping the compensation paid by each corporation was based on 
the approximate amount of time devoted to that corporation.  Incat paid Mr. 
Bowman approximately $3,000 a month from January 1996 until he resigned from 
Incat on December 20, 1996.  Mr. Austin , who assumed his present capacity

For the year ended December 31, 1996, other IST subsidiaries served 
as sub-contractors  to Incat in the ordinary course of business.   The 
amount of sub-contractor revenue to other IST subsidiaries was 
approximately $1,085,000 for the year ended December 31, 1996.   
Management believes the rates paid to other IST subsidiaries are 
commercially reasonable.

IST owns a majority of the common stock and all the Series A and 
Series B Preferred Stock of AES.  See Item 12; "Security Ownership of 
Certain Beneficial Owners and Management; Changes in Control".  The 
owner of each share of common stock and of the Series A and Series B 
Preferred stock of AES has one vote per share.  As a result of IST's 
ownership of  stock of AES, the approval of IST would be required in order 
for AES to effect an extraordinary transaction under the corporate laws of 
the State of  New York, the state of incorporation of AES.  Certain 
agreements between IST and its security holders contain certain restrictions 
which provide that the consent of a majority of IST's holders of preferred 
stock and other securities must be obtained before IST may approve an 
extraordinary transaction involving AES.

Also, pursuant to a guarantee made by IST of certain notes made by its 
direct wholly owned subsidiary, certain shares of  AES stock owned by 
IST have been pledged to a group of individuals and entities controlled 
by persons who serve on the Board of Directors of IST.  These individuals
constitute a majority of the Board of Directors of  IST.  See Item 12; 
"Security Ownership of Certain Beneficial Owners and Management;
Changes in Control".
