Mr. Scharf's surviving spouse during her lifetime; (iv) annual grants of
stock options as determined by the Compensation Committee of Niagara's
Board of Directors; and (v) medical coverage and specified fringe benefits.

     If Mr. Scharf's employment is terminated by Niagara without Cause (as
defined in the Employment Agreement) or by Mr. Scharf due to a breach of
the Employment Agreement by Niagara, Niagara will (i) provide Mr. Scharf
with a lump sum amount equal to the product of (A) the greater of three and
the number of years remaining in the term of the Employment Agreement
("Severance Multiple"), and (B) the sum of Mr. Scharf's then current Annual
Base Salary and the greater of Mr. Scharf's three-year average annual bonus
and the target bonus for the year of termination; (ii) provide Mr. Scharf
with a pro rata bonus for the year of termination; (iii) for the number of
years equal to the Severance Multiple provide Mr. Scharf with additional
years of service credit under the SERP, continued life insurance benefits
and continued exercisability of stock options; and (iv) cause all of Mr.
Scharf's outstanding equity awards to vest. Mr. Scharf would also receive a
gross-up payment for any excise tax payable under Section 4999 of the
Internal Revenue Code of 1986, as amended.

Frank Archer and Raymond Rozanski

     Niagara and Niagara LaSalle entered into employment agreements with
each of Frank Archer and Raymond Rozanski (each, an "Executive") dated
August 16, 1995 (the "Archer/Rozanski Agreements"), providing, among other
things, that they will continue to serve as President and Executive Vice
President, respectively, of Niagara LaSalle for a period of five years. The
Archer/Rozanski Agreements provide that each Executive will be entitled to
(i) an annual base salary of not less than $175,000 adjusted for increases
in the consumer price index (which amount has subsequently been increased
to $225,000); (ii) cash bonuses determined by the Compensation Committee of
Niagara's Board of Directors; (iii) options to purchase 200,000 shares of
Niagara Common Stock ("Options"); (iv) medical, dental and life insurance
coverage; and (v) certain specified fringe benefits.

     If the Executive's employment is terminated by Niagara other than for
incapacity or certain specified acts (i) the Executive would receive his
annual base salary through the end of the five-year term (the "Employment
Period"); (ii) subject to continued compliance with certain confidentiality
and non-competition obligations, the Executive would receive one-half of
his annual base salary (as then in effect) payable over the one-year period
following expiration of the Employment Period; (iii) the Executive would
continue to receive medical, dental and life insurance coverage, subject to
the terms of the applicable plans, through the end of the Employment
Period; and (iv) all Options would immediately vest and become exercisable
for a period of one year.


COMPENSATION OF DIRECTORS

     The members of the Board of Directors are compensated in a manner and
at a rate determined from time to time by the full Board. Since 1996,
Niagara has granted non-qualified stock options to its outside directors as
compensation for their service as a director. On January 28,1999, each
member of the Board of Directors, other than Michael Scharf and Frank
Archer, received as compensation for his service as a director, a
non-qualified stock option (collectively, the "Director Options") to
purchase 10,000 shares of Niagara Common Stock exercisable at $5.875 per
share. Each Director Option became exercisable as to 2,000 of the
underlying shares on the date of grant and becomes exercisable as to an
additional 2,000 of the underlying shares on each of the first through
fourth anniversaries of the date of grant, provided the holder is then
serving as a director of Niagara. Upon a "change in control" of Niagara (as
defined in Niagara's 1995 Stock Option Plan), each Director Option will
become exercisable in full.

     Niagara maintains directors and officers liability insurance which
insures directors and officers of Niagara and its subsidiaries against
certain liabilities by them while serving in such capacities, and
reimburses Niagara for certain indemnification payments made by Niagara to
directors and officers of Niagara and its subsidiaries. This policy extends
through March 12, 2001 at a total premium of $215,000. No claims have been
made under this policy.


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Compensation Committee of the Board of Directors is currently
comprised of Gerald L. Cohn and Douglas T. Tansill. There are no
"interlocks" as defined by the SEC with respect to any director who serves
or for any part of 1999 served as a member of the Compensation Committee.

ITEM 13.       CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS


        Andrew Heyer, a director of Niagara, is a Managing Director of CIBC
World Markets Corp. which has provided investment banking and financial
advisory services to Niagara and Niagara LaSalle prior to 1999. CIBC World
Markets Corp. is a subsidiary of CIBC Inc., which is one of five banks who
are parties to a $90 million revolving credit and term loan agreement with
Niagara LaSalle and LaSalle, the obligations of which are guaranteed by
Niagara. CIBC Inc.'s commitments under this credit agreement total $20
million. In addition, CIBC Inc. issued a (pound)9.8 million (approximately
$15.7 million) standby letter of credit which indirectly secured Niagara
UK's obligations under a (pound)19.8 million (approximately $31.7 million)
bank facilities agreement guaranteed by Niagara and entered into on May 21,
1999 in connection with Niagara UK's acquisition of eight U.K. steel bar
businesses. This letter of credit expired on December 31, 1999.

        On December 5, 1997, Niagara loaned Gilbert Scharf $600,000, the
proceeds of which were used by him to exercise Redeemable Common Stock
Purchase Warrants of Niagara, which, having been called for redemption,
were not exercisable after December 11, 1997. The loan was evidenced by a
Promissory Note (the "Original Note") executed by Mr. Scharf in favor of
Niagara and due on December 4, 1998. Interest on the unpaid principal
amount of the Original Note accrued at 5.68% per annum. The Original Note
required installment payments of principal following the sale of shares of
Niagara Common Stock by Mr. Scharf in amounts equal to the proceeds from
such sales. In addition, the Original Note permitted prepayments of
principal without premium or penalty. During December 1998, Niagara
extended the maturity date of the Original Note by one year and Mr. Scharf
paid $100,000 of principal and all accrued interest due thereunder. All
other terms of the Original Note remained the same. The foregoing were
reflected in an Amended and Restated Promissory Note dated December 15,
1998 and due on December 4, 1999 (the "Amended Note") issued by Mr. Scharf
to Niagara in exchange for the Original Note. During December 1999, Mr.
Scharf paid Niagara all amounts due on the Amended Note. Mr. Scharf is the
Secretary and a director of Niagara and, until March 1998, was a Vice
President of Niagara and its Treasurer. He is the brother of Michael Scharf
who is the Chairman of the Board, Chief Executive Officer and President of
Niagara.
