ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Georgia Business Corporation Code permits a corporation to eliminate or
limit the personal liability of a director to the corporation or its
shareholders for monetary damages for breach of duty of care or other duty as a
director, provided that no provision shall eliminate or limit the liability of a
director: (A) for any appropriation, in violation of his duties, of any business
opportunity of the corporation; (B) for acts or omissions which involve
intentional misconduct or a knowing violation of law; (C) for unlawful corporate
distributions; or (D) for any transaction from which the director received an
improper personal benefit. This provision pertains only to breaches of duty by
directors in their capacity as directors (and not in any other corporate
capacity, such as officers) and limits liability only for breaches of fiduciary
duties under Georgia corporate law (and not for violation of other laws, such as
the Federal securities laws). The Company's Restated and Amended Articles of
Incorporation (the "Restated Articles") exonerate the Company's directors from
monetary liability to the extent permitted by this statutory provision.
 
     The Company's Bylaws (the "Bylaws") also provide that the Company shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (including any action by or in
the right of the Company), by reason of the fact that such person is or was a
director or officer of the Company, or is or was serving at the request of the
Company as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including reasonable
attorneys' fees), judgments, fines, and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding, if such person acted in good faith and in a manner such person
reasonably believed to be in or not opposed to the best interests of the Company
(and with respect to any criminal action or proceeding, if such person had no
reasonable cause to believe such person's conduct was unlawful), to the maximum
extent permitted by, and in the manner provided by, the Georgia Business
Corporation Code. In addition, the Bylaws provide that the Company will advance
to its directors or officers reasonable expenses of any such proceeding.
 
                                      II-1

     Notwithstanding any provision of the Company's Restated Articles and Bylaws
to the contrary, the Georgia Business Corporation Code provides that the Company
shall not indemnify a director or officer for any liability incurred in a
proceeding in which the director is adjudged liable to the Company or is
subjected to injunctive relief in favor of the Company: (1) for any
appropriation, in violation of his duties, of any business opportunity of the
Company; (2) for acts or omissions which involve intentional misconduct or a
knowing violation of law; (3) for unlawful corporate distributions; (4) for any
transaction from which the director or officer received an improper personal
benefit.
 
     Section 8 of the Underwriting Agreement filed as Exhibit 1.1 hereto also
contains certain provisions pursuant to which certain officers, directors and
controlling persons of the Company may be entitled to be indemnified by the
underwriters named therein.
 
     The Company has purchased insurance with respect to, among other things,
any liabilities that may accrue under the statutory provisions referred to
above.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreements, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification by the Registrant for liabilities arising under
the Securities Act of 1933 (the "Securities Act") may be permitted to directors,
officers and controlling persons of the Registrant pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer, or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer, or
controlling person in connection with the securities being registered hereunder,
the Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
     The Registrant hereby undertakes that:
 
     (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.
 
     (2) For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

Holidays Include: New Years Day, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day, and Christmas Day.

Overtime must be approved by United in advance of being incurred.  In order to
cover irregular operations, overtime will, be mandatory.  United Airlines can
have work schedules changed up to 72 hours (3 days) prior to the needed change
without being charged overtime. Such rates and charges will be firm for the
above-stated dates. Thereafter, either party may request a price review by
written notice to the other party, which review will be conducted within 30 days
after such notice.  Failing agreement, either party may terminate the Security
Agreement upon 60 days written notice, to allow the parties time to make
alternate arrangements.

B.    The prices in this Agreement will be subject to renegotiation if any law,
regulation, or ruling of any governmental authority having jurisdiction over the
subject matter is enacted that alters the costs of performing the Security
Services under this Agreement.

C.    Vendor will undertake that United will not be commercially disadvantaged
regarding Vendor's service/pricing arrangements under this Agreement as compared
against the service/pricing arrangements offered by Vendor to any competitor of
United that Vendor may service in a reasonably similar manner at any Airport.
Vendor represents and warrants that the hourly rates, fees, prices, terms, and
conditions (collectively "Prices") for personnel, overtime, supervision,
training, and other charges (collectively "Security Services") under this
Agreement are at least as low as the Prices provided to other customers by
Vendor for comparable Security Services at the Airport or at any comparable
airport.  If Vendor offers or grants to another customer a Price for any
Security Service that is lower than the Price paid by United for a substantially
similar Security Service, then Vendor immediately will offer such lower Price to
United.

8.    Settlement: Vendor will invoice United semi-monthly, in accordance with
the prices set forth above, which invoice will provide reasonable detail
regarding services provided, including a statement of hours worked per position
and rates charged.  Security employees must sign in for work on a United
provided sign-in log.  The cost of Vendor senior management personnel will be
allocated to United only with United's prior consent.  United will pay Vendor
upon receipt of and in accordance with Vendor's invoices. United will pay such
invoices within 30 days of date of invoice.

9.    Taxes: United will pay any sales, use, or personal property taxes imposed
by any taxing authority and required to be paid by United or Vendor as a result
of services provided to United under this Agreement. United will not be liable
for any tax levied upon or measured by the income of Vendor,

10.   FAA Violations Fines: Fines levied against the airlines by the FAA for
security violations shall be recovered from Vendor if violation is attributed
to Vendor deficiencies and/or negligence. These shall include, but not be
limited to, checkpoint personnel errors, inadequate training, manpower
shortages, noncompliance with government regulations, etc.  Vendor's liability  
for any civil penalty assessed as a result of an FAA test failure shall be full
payment for fines arising out of any one occurrence.  Payment will be due 30
days from notification by United Airlines after resolution of fine amount
between United and the FAA.

specified by United.  Vendor will use all reasonable efforts to maintain
standards for Security Services provided by Vendor under this Agreement that
meet all relevant legislation and regulations, including without limitation the
Federal Aviation Administration Air Carrier Standard Security Program and State
of Illinois regulations. United may at its cost provide representatives who may
inspect the provision of Security Services under this Agreement and provide
advice and direction to Vendor.

as United reasonably requires relating to the Services provided by Vendor under
this Agreement Vendor will maintain records documenting "dangerous goods"

On a regular basis as specified by United's designated manager, Vendor will
provide to United a complete copy of all such daily registers.

B.    To the extent that Vendor is required by law or by any regulatory
authority to maintain record of background investigations, training, or other
qualification or certification of employees or agents of Vendor performing
services under this Agreement, upon expiration or termination of this Agreement
for any reason, Vendor will make available to United all such records, or
certified copies thereof.  All training records are the property of United
Airlines and shall remain on United Airlines' property.

13.   Personal Services: Vendor will not subcontract or delegate to any third
party any of Vendor's duties or responsibilities under this Security Agreement
without the prior written consent of United.  Any approved delegation or
sub-contracting will not relieve Vendor of its responsibilities under this
Agreement and Vendor will remain fully liable for all performance hereunder,

magnetometers.  Vendor will ensure that the Equipment is operated only by
employees trained to do so.  United retains all rights, title, and interest in

Equipment is in the possession and control of Vendor.  Vendor is responsible
for customer belongings going through x-ray. Vendor will reimburse customer for
destruction and/or loss/theft of any personal property.  Vendor will provide

warranty, express or otherwise, that the services furnished shall avert or
prevent occurrences or consequences therefrom. The amounts payable to

rendered and are unrelated to the value of Client's property or the property of
others located in or about Client premises. The services provided under this
Agreement are solely for the benefit of the Client and neither this Agreement
nor any services rendered hereunder shall give rise to, or shall be deemed to or
construed so as to confer any rights on any other party as a third party

claims by such third parties.
 
Notwithstanding anything contrary herein Argenbright shall not be liable to

agents may be found to have been negligent in the performance of its or their
duties.

actual damages, if any, of Client arising out of Argenbright's performance or
failure to perform hereunder; that Argenbright's maximum liability to Client
arising out of or relating to this Agreement except when such damage is a result
of an act, negligence, fault, or omission of Argenbright's officers, employees
or agents or Argenbright's performance or non-performance of services for
Client, whether based on contract, tort, law, equity or otherwise, shall be
limited to Argenbright's total amount of fees paid when due by client within the
12 month period following the first commencement of services hereunder by
Argenbright, as liquidated damages and not as a penalty, and this liability of
Argenbright shall be exclusive. Parties on their own behalf and on behalf of
their insurers waives all rights of subrogation, except if arising from an act,
negligence, fault, or omission by the other party, officers, employees, or
agents. Argenbright shall not be liable for failure to perform this Agreement
