                                    EXHIBIT B

                            ATT COMPLIANCE MEMORANDUM

                        THE FOREIGN CORRUPT PRACTICES ACT

         ATT employs an extensive network of sales representatives and other
employees throughout the world who come into daily contact with officials of
foreign governments. Relationships with these officials, while essential to the
conduct of the Company's business, raise the possibility of demands from such
officials for payments or other compensation in connection with decisions or
actions within their control that affect the Company.

         Each employee of the Company must become familiar with the laws of the
United States that regulate interactions with foreign officials. To that end,
you are being provided with this guide to the requirements of the Foreign
Corrupt Practices Act (the "FCPA"), which is the main statute governing
interactions between American business people and foreign governments. The
Company urges you to read this guide and retain it for future reference. The
FCPA is a criminal statute and provides for severe CRIMINAL penalties, as
outlined below.

         IF AT ANY TIME YOU HAVE QUESTIONS CONCERNING THE APPROPRIATE COURSE OF
CONDUCT IN A PARTICULAR SITUATION INVOLVING A FOREIGN OFFICIAL OR THE PROPRIETY
OF ANY REQUEST, CONTACT EDMUND JEFFREY MORIARTY, THE COMPANY'S GENERAL COUNSEL,
AT (561) 791-5000, EXT. 1408.

                              PROHIBITED ACTIVITIES

ANTI-BRIBERY PROVISIONS: THE FCPA MAKES IT UNLAWFUL FOR AN AMERICAN CORPORATION
OR ITS EMPLOYEES , AGENTS OR REPRESENTATIVES, DIRECTLY OR INDIRECTLY, TO PAY OR
TO OFFER TO PAY OR TO AUTHORIZE PAYMENT OF ANYTHING OF VALUE TO ANY FOREIGN
OFFICIAL, FOREIGN POLITICAL PARTY OR FOREIGN POLITICAL PARTY OFFICIAL FOR THE
PURPOSE OF RETAINING OR OBTAINING BUSINESS.

ACCOUNTING PROVISIONS: The FCPA requires the Company to keep reasonably detailed
accounting records that accurately and fairly reflect the transactions and
dispositions of assets of the Company.

                                   Key Points:

         -While the anti-bribery provisions of the FCPA extend only to officials
         of foreign governments, foreign political parties and foreign political
         party officials, you may violate the FCPA if you make a payment to a
         private party and you know, believe or are aware that the private party
         intends to turn over all or a portion of that payment to a foreign
         official. Hiding one's head in the sand is not an option.




                                    Ex. B - 1

<PAGE>   20




         -Although the typical circumstance covered by the FCPA is the awarding
         of government contracts, the FCPA is not limited to such matters. The
         key is whether a payment or offer is made to a foreign official, not
         whether the transaction is with the foreign government. For purposes of
         compliance with the FCPA, officials of government-owned corporations
         are to be considered "foreign officials" (many airlines are wholly or
         partly government-owned corporations).

         -Failure to accurately inform the appropriate officials of the Company
         as to the nature of transactions entered into by you, including any
         payments made, can expose the Company to liability under the FCPA
         independent of any violation of the anti-bribery provisions. It is
         imperative that accurate and detailed record-keeping be maintained and
         provided to the appropriate Company officials.

                                   EXEMPTIONS

ROUTINE GOVERNMENTAL ACTIONS: The FCPA exempts from its coverage payments made
to a foreign official, foreign political party or foreign political party
official for the purpose of facilitating or expediting the performance of a
routine governmental action by any such person or party. Under the FCPA, the
definition of "routine governmental action" encompasses action by a foreign
official in (i) obtaining permits, licenses or other official documents that
qualify a person to do business; (ii) processing governmental papers, such as
visas and work orders; (iii) providing police protection or mail services or
scheduling inspections; (iv) providing communication services, utilities, or
cargo handling or (v) actions of a similar nature. "Routine governmental action"
does not include any decision to award new business to or continue business with
a particular party.

                                   Key Points:

         -The routine governmental actions exemption is an acknowledgment that
         in many countries officials demand compensation for performing ordinary
         services. The critical distinction is between payments made for routine
         services and payments designed to obtain or retain business. The FCPA's
         definition of routine governmental action, outlined above, provides
         some guidance. Careful consideration of each such instance is required
         to ensure compliance; if you are unsure about a requested payment,
         contact the Company BEFORE agreeing to make it.

                   DEFENSES TO AN ALLEGATION OF FCPA VIOLATION

COMPLIANCE WITH FOREIGN LAW: Prosecution under the FCPA can be avoided if the
payment or offer of anything of value allegedly made to a foreign official,
foreign political party or foreign political party official was lawful under the
written laws and regulations of the foreign country involved.

                                   Key Points:

         In the event that a payment or offer is made or demanded on the basis
         that it is lawful under the foreign country's laws, it is critical that
         you inform the appropriate officials of the Company so that you and the
         Company can obtain the advice of legal counsel BEFORE any payment or
         offer is made.

         -You should not rely on oral or written assurances or on advice of
         counsel not retained by the Company as to the applicability of a
         foreign country's laws in such a situation.

PROMOTIONAL OR CONTRACTUAL EXPENSES: Payments or offers of anything of value to
a foreign official do not violate the FCPA if such payments or offers were
reasonable and bona fide expenditures incurred by or on behalf of the foreign
official and were directly related to (i) the promotion, demonstration or
explanation of products or services; or (ii) the execution or performance of an
existing contract with a foreign government or agency thereof.

                                   Key Points:

         -This defense permits the Company to pay or offer to pay expenses such
         as travel and lodging expenses of foreign officials without violating
         the FCPA. Note that the expenses have to be reasonable, i.e.,
         appropriate to the nature of the transaction or the individual
         involved, and have to be bona fide, i.e., actually incurred for the
         purpose of promoting the product or service or executing or performing
         an existing contract.

                                    PENALTIES

         Power to enforce the provisions of the FCPA is divided between the
Securities and Exchange Commission and the United States Department of Justice.
The SEC enforces the record-keeping and accounting provisions and may bring a
civil enforcement action or administrative proceeding against any company it
believes to have violated the FCPA. The Justice Department enforces the
anti-bribery provisions of the FCPA and brings any criminal charges under the
accounting sections.






                                    Ex. B - 3
<PAGE>   22



INDIVIDUAL PENALTIES: Any officer or director of a company who willfully
violates the anti-bribery provisions of the FCPA may be fined up to $100,000, or
imprisoned for five years, or both. ANY EMPLOYEE, AGENT OR REPRESENTATIVE OF A
COMPANY WHO IS A UNITED STATES CITIZEN, NATIONAL OR RESIDENT OR IS OTHERWISE
SUBJECT TO U.S. JURISDICTION AND WHO WILLFULLY VIOLATES THE ANTI-BRIBERY
PROVISIONS MAY BE FINED UP TO $100,000, OR IMPRISONED FOR UP TO FIVE YEARS, OR
BOTH. THE COMPANY MAY NOT PAY THE FINE OF AN INDIVIDUAL WHO IS CONVICTED OF
VIOLATING THE FCPA.

CORPORATE PENALTIES: A corporation found to have violated the FCPA may be fined
up to $2,000,000.

                                    RED FLAGS

         In the event that you engage in dealings with foreign officials or
enlist representatives or contractors to deal with foreign officials, you must
be mindful of the provisions of the FCPA and comply with them. It is imperative
that you keep accurate, timely and comprehensive records of your dealings with
foreign officials and in particular any payments made when dealing with foreign
officials or their or your agents. Be on the lookout for the following abnormal
features of a transaction that might alert you to a possible violation of the
FCPA:

         -EXCESSIVE FEE PAYMENTS. In hiring an agent or making payments to
         foreign officials, you must ensure that the fee, commission or payment
         being charged, in the case of a representative, or the contract price,
         in the case of an official, is fully documented and not excessive in
         light of prevailing market conditions.

         -PAYMENTS IN CASH OR BEARER INSTRUMENTS OR TO THIRD PARTIES. Do not
         make any significant payments in cash or use checks made out to bearer
         or to cash. If a payment is to be made to a party who is not typically
         a party to the type of transaction in question, contact the Company for
         instructions BEFORE agreeing to make the payment.

                          REPRESENTATIVES ARRANGEMENTS

         Retaining a representative to solicit sales or effect transactions in a
foreign country requires that special care be undertaken in selecting the
representative and monitoring his or her activities. Special precautions include
the following:

         -KNOW YOUR REPRESENTATIVE. In selecting a representative, you should
         consider who has recommended him or her to you and the experience of
         the representative. You should clearly define the particular tasks that
         the agent is being hired to perform. You should ensure that the
         representative is familiar with the FCPA. You should familiarize
         yourself with the law and business customs of the foreign country in
         which the representative is to work for you.



                                    Ex. B - 4




<PAGE>   23

         -PROMISES. Any agreement with a representative should include
         provisions to the effect that (i) the representative is aware of and
         will comply with the FCPA, (ii) the representative will not accept any
         payments offered to him or her in an illegal fashion, (iii) the Company
         has the right to cancel the agreement in the event that the Company
         believes in good faith that the representative has violated or has
         caused the Company to violate the FCPA, and (iv) the representative
         will disclose any subagents and promise not to hire any subagents
         without your express written permission. ALL AGREEMENTS, WRITTEN OR
         ORAL, WITH REPRESENTATIVES REQUIRE THE PRIOR WRITTEN CONSENT OF THE
         PRESIDENT OF THE COMPANY.
