4.    Borrowings

On November 30, 2000, the Company signed two new credit agreements with HSBC Bank USA ("HSBC"). The first agreement is for a $10 million domestic
revolving credit facility to support the Company's routine working capital and standby letter of credit needs. The second is a $30 million export credit and security agreement, guaranteed by
the Export-Import Bank of the United States ("Ex-Im"), to support the Company's overseas contract, trade finance and working capital needs. The credit facility bears an interest rate of
the HSBC Bank USA prime rate or LIBOR plus 2.0% at the Company's option. On February 14, 2002, these credit agreements were amended to increase the domestic revolving credit facility to
$20 million and to reduce the export credit facility to $20 million. The domestic revolving credit facility as amended provides for maximum borrowings in an amount up to the lower of:
(a) the sum of 85% of eligible domestic accounts receivable plus the lower of: (i) 40% of eligible raw materials and work-in-process inventory; or; (ii) $5.0 million, or;
(b) $20.0 million. The export credit and security agreement as amended provides for maximum borrowings in an amount up to the lower of: (a) the sum of 90% of eligible
international billed and unbilled accounts receivable, or; (b) $20.0 million. The agreements expire on November 30, 2002.

At
December 31, 2001, $9.3 million in borrowings were outstanding and $3.8 million in letters of credit were in effect against this credit facility. The Company's
credit facility restricts the payment of dividends, except in shares of the Company's stock, without consent of the bank. The credit facility requires the Company to meet certain financial covenants.
As of December 31, 2001, the Company was not in compliance with one of these financial covenants, but has obtained a waiver from the bank for this non-compliance.

AMERICAN SCIENCE AND ENGINEERING, INC.  ITEM 2MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL  CONDITION AND RESULTS OF OPERATIONS

Overview

In the third quarter of fiscal 2002 net sales and contract revenues were $14,178,000, a 17% decrease from the comparable period a year ago and an 8% decrease from
the previous quarter. The Company had a net loss of $1,792,000 in the current quarter, compared to a net profit of $211,000 in the corresponding period a year ago and a net loss of $797,000 in the
previous quarter.

Results of Operations

Net sales and contract revenues in the third quarter decreased by $2,840,000 (16.7%) in comparison to the corresponding period a year ago and decreased by
$1,256,000 (8.1%) compared to the second quarter of fiscal 2002. This decrease in revenues from the previous quarter is due to reduced sales of the Company's cargo products during the quarter. This
reduction in cargo sales was offset in part with higher sales of the Company's parcel products which experienced a significant increase in orders and shipments
post-September 11th.

For
the third quarter, costs of sales and contracts decreased to $11,008,000 from $12,828,000 in the corresponding period a year ago. Costs of sales and contracts represented 77.6% of
revenues versus 75.4% for the corresponding period last year and 78.1% for the second quarter of fiscal year 2002. The costs of sales as a percentage of revenue in the current quarter increased from
the corresponding period last year due to the lower margins on certain cargo projects recorded on a percentage of completion basis partially offset by increased sales of parcel products which are
higher margin sales.

Selling,
general and administrative expenses of $4,274,000 for the third quarter were higher by 70.0% compared to the corresponding period last year and higher by 47.1% compared to the
second quarter of fiscal 2002. As a percent of sales, selling, general and administrative expenses were 30.1% of revenues in the current quarter compared to 14.8% of revenues for the corresponding
period a year ago and 18.8% for the second quarter of fiscal year 2002. This increase was due primarily to increased legal costs associated with a patent infringement case settled during the third
quarter of 2002 (see Item 1Legal Proceedings).

Company-funded
research and development expenses of $1,628,000 for the third quarter increased by $324,000 (24.8%) compared to the corresponding period last year and remained relatively
constant with costs incurred in the second quarter of fiscal year 2002. The current quarter expenditures focused on new product initiatives and improvements with certain projects initiated in direct
response to potential market demand identified as a result of the events of September 11th.

A
tax benefit of $1,099,000 has been recorded in the third quarter compared to a tax provision of $30,000 in the corresponding period in the prior year.

The
Company incurred a net loss of $1,792,000 during the third quarter of fiscal 2002. The Company had net income of $211,000 in the third quarter of fiscal 2001 and a net loss of
$797,000 in the second quarter of fiscal 2002.The increase in the current quarter net loss can be attributed to the lower revenues and gross margins
and increased selling, general and administrative costs offset by an increased tax benefit.

Liquidity and Capital Resources

Cash and cash equivalents increased by $3,631,000 to $4,837,000 at December 31, 2001 compared to $1,206,000 at March 31, 2001. This increase in cash
and cash equivalents was primarily due to decreases in unbilled costs and fees, proceeds received from the exercise of stock options, additional

borrowings against the line of credit and the repayment of an officer's loan offset in part by increases in inventories, accounts receivable and prepaid expenses and decreases in certain liabilities.
Working capital increased by $1,909,000 (11.4%) since March 31, 2001, increasing from $16,751,000 to $18,660,000 at the end of the third quarter due to the inventory and receivable increases
noted.

On
November 30, 2000, the Company signed two new credit agreements with HSBC Bank USA ("HSBC"). The first agreement is for a $10 million domestic revolving credit facility
to support the Company's routine working capital and standby letter of credit needs. The second is a $30 million export credit and security agreement, guaranteed by the Export-Import Bank of
the United States ("Ex-Im"), to support the Company's overseas contract, trade finance and working capital needs. The credit facility bears an interest rate of the HSBC Bank USA prime rate
or LIBOR plus 2.0% at the Company's option. On February 14, 2002, these credit agreements were amended to increase the domestic revolving credit facility to $20,000,000 and to reduce the export
credit facility to $20,000,000. The domestic revolving credit facility as amended provides for maximum borrowings in an amount up to the lower of: (a) the sum of 85% of eligible domestic
accounts receivable plus the lower of: (i) 40% of eligible raw materials and work-in-process inventory; or; (ii) $5.0 million, or; (b) $20.0 million. The export
credit and security agreement as amended provides for maximum borrowings in an amount up to the lower of: (a) the sum of 90% of eligible international billed and unbilled accounts receivable,
or; (b) $20.0 million. The agreements expire on November 30, 2002.

At
December 31, 2001, $9.3 million in borrowings were outstanding and $3.8 million in letters of credit were in effect against this credit facility. The Company's
credit facility restricts the payment of dividends, except in shares of the Company's stock, without consent of the bank. The credit facility requires the Company to meet certain financial covenants.
As of December 31, 2001, the Company was not in compliance with one of these financial covenants, but has obtained a waiver from the bank for this non-compliance.

PART IIOTHER INFORMATION

Item 1Legal Proceedings

The United States Court of Appeals for the Federal Circuit in Washington, D.C., in a decision issued December 29, 1999, ruled that American
Science & Engineering, may pursue a patent infringement claim against Vivid Technologies which produces x-ray detection devices used in baggage scanning equipment.

The
Appeals Court overturned a 1998 decision in Vivid's favor by the U.S. District Court in Massachusetts. The lawsuit filed in May 1996, concerns whether Vivid's
x-ray detection devices infringed on the Company's patent. The District Court had ruled that the Company could not assert a claim that Vivid's devices infringed on the Company's patent.
The Appeals Court also reversed the district court's finding on summary judgment that Vivid did not infringe on the Company's patent, as well as the district court's denial of the Company's request
for discovery to oppose Vivid's summary judgment motion. Discovery is now proceeding.

In
September 1998, the Company filed suit against EG&G Astrophysics Research Corp. ("EG&G") in U.S. District Court in Massachusetts claiming that EG&G is infringing on at least
two patents owned by the Company and that EG&G has misappropriated certain trade secrets of the Company. In February 1999, the Company filed a related action in the same court against the U.S.
Customs Service ("Customs") alleging that Customs had either misappropriated the Company's trade secrets or facilitated their misappropriation by EG&G and that Customs had improperly entered into a
contract with EG&G for the acquisition of a product functionally equivalent to MobileSearch x-ray inspection system. In May 1999, the Court held a hearing on the
Company's motion for a preliminary injunction against both Customs and EG&G prohibiting further performance of the contested contract and preventing EG&G from utilizing the Company's trade secrets. In
August 1999, the Court issued a ruling denying the request for the preliminary injunction. In December 1999, EG&G filed a motion for summary judgment that EG&G did not misappropriate the
Company's trade secrets and in March 2000 EG&G filed a motion for summary judgment that EG&G did not infringe the Company's patents. In February 2001, the court denied EG&G's and the
Company's motions for summary judgment. The Company is continuing to pursue its claims against EG&G, but the suit against U.S. Customs Service has been dismissed.

In
a related matter, EG&G had filed a request with the U.S. Patent and Trademark Office ("USPTO") for re-examination of the two patents that currently are at issue in the
patent infringement action described above. The Company filed oppositions to the re-examination requests and was advised by the USPTO that the Company's MobileSearch x-ray
inspection patent was upheld in all material respects. The Company has now also been advised by the USPTO that the Company's patent on its Z® Backscatter x-ray inspection
technology has been upheld in all material respects.

In
February 2000, Heimann Systems GmBH ("Heimann") filed a civil action in U.S. District Court in Massachusetts against the Company alleging that the Company infringed a Heimann
patent relating to a mobile vehicle and x-ray examining device. In December 2001, Heimann and the Company agreed to a settlement of the case. The settlement provides a mutually
satisfactory business arrangement that permits the parties to compete in the marketplace with their respective approaches to mobile x-ray inspection systems.
