                    AMENDMENT NO. 1 TO EMPLOYMENT AGREEMENT


     This Amendment No. 1 to Employment Agreement (this "Amendment") is made to
the Employment Agreement by and among Morrie K. Abramson and Kent Electronics
Corporation, a Texas corporation (the "Agreement"), and entered into by and
among Morrie K. Abramson, Rolaine S. Abramson and Kent Electronics Corporation
as of August 18, 1997.

     1.   Rolaine S. Abramson is hereby added as a party to the Agreement.

     2.   The parties hereby amend Section 4.4(a) of the Agreement in its
entirety to read as follows:

          4.4  Benefits Following Termination of Employment

               (a)  Upon the termination of Employee's employment by the
     Company, whether due to death, Disability, resignation, whether or not for
     Good Reason, or discharge, whether or not for Just Cause, the Company
     shall, commencing on the first day of the month following the date of the
     termination of Employee's employment, pay, or cause to be paid, to Employee
     in equal monthly installments the sum of $750,000 per year (the "Annual
     Amount"), for a period equal to the greater of (x) 15 years, (y) the life
     of Employee, or (z) the life of Rolaine S. Abramson so long as she is
     married to Employee at the date of Employee's death ("Employee's Spouse");
     provided, however, that in the event of the termination of Employee's
     employment due to death or Disability prior to March 31, 2001, the Annual
     Amount described above shall equal $950,000 until March 31, 2001, after
     which time the Annual Amount shall equal $750,000; and provided further
     that Employee shall not be entitled to any amounts under this Section 4.4
     if Employee's employment is terminated prior to a Change in Control for
     Just Cause or without Good Reason.  In addition, the Annual Amount shall be
     adjusted annually to reflect increases in the cost of living after the date
     hereof, as measured by the Consumer Price Index ("CPI") for all urban
     consumers calculated by the Bureau of Labor Statistics (or any successor or
     replacement index).

               (i) If Employee shall die before Employee's Spouse and Employee's
     Spouse is married to Employee at the date of Employee's death, whether
     before or after the payments of the Annual Amount described above shall
     have commenced, then the Annual Amount shall be paid in monthly
     installments to Employee's Spouse.  If Employee's Spouse then dies before
     all amounts required to be paid have been paid, then, upon the death of
     Employee's Spouse, any remaining payments of the Annual Amount shall be
     made to the personal representative of the estate of Employee's Spouse, to
     pass as a part thereof.

               (ii) If Employee's Spouse shall die before Employee, then any
     community property interest of Employee's Spouse in this Agreement shall
     vest in

     Employee. If Employee then dies before all amounts required to be paid have
     been paid, then, upon Employee's death, any remaining payments of the
     Annual Amount shall be made to Employee's beneficiary designated in writing
     to the Company by Employee, or in the absence thereof, to the personal
     representative of the estate of Employee, to pass as a part thereof.

     3.   The parties hereby amend Section 6.3 of the Agreement in its entirety
to read as follows:

          6.3  Death.  The death of Employee shall result in the termination of
     the Term of Employment, and Employee's Spouse, or if Employee's Spouse
     predeceases him, the personal representative of the estate of Employee or
     designated beneficiary shall be entitled to the benefits described in
     Section 4, including, without limitation, Sections 4.4 and 4.5. The Company
     shall not be obligated to pay Employee's Spouse, or if Employee's Spouse
     predeceases him, the personal representative of the estate of Employee or
     designated beneficiary any sums of money pursuant to Section 4.1 other than
     a cash lump-sum payment equal to all compensation and benefits due Employee
     at the date of his death (all cash compensation to be based on annual cash
     compensation of not less than $950,000 per year irrespective of the time at
     which such cash compensation is otherwise payable) annualized on a
     reasonable basis acceptable to the estate or personal representative of
     Employee; however, if at the end of such year it is determined that
     Employee's annual compensation would have been higher than the annualized
     amount used to calculate this payment, the Company shall pay Employee's
     Spouse or if Employee's Spouse predeceases him, the personal representative
     of the estate of the Employee or designated beneficiary an amount in a cash
     lump sum equal to a proportionate share in the increase based on his period
     of employment during the year in which Employee died.  Employee's other
     compensation and benefits under this Agreement, including without
     limitation those provided pursuant to Sections 4.4 and 4.5, shall not be
     impaired or otherwise adversely affected by termination of Employee's
     employment on account of death.
