Exhibit 10.28a
 AMENDED AND RESTATED
AGREEMENT CONCERNING DISABILITY AND DEATH
      1.
    
    Meridian shall make a monthly payment to Motto for up to 60 months if
Motto meets the definition of Disability in Section 5 below while employed by
Meridian. The gross amount of each monthly payment shall be equal to 60% of the
average total annual salary and bonus paid by Meridian to Motto during Meridians
three fiscal years ending immediately before Mottos Disability commenced divided
by twelve. Any such payments to Motto shall be reduced by the gross amount of any
payments made to Motto through any group or other disability insurance policy or
program maintained by Meridian. Provided, however, that no such monthly payment
shall be made after either the month of Mottos death or the month that Motto
ceases to meet the definition of Disability in Section 5 below. Meridian may
fulfill its obligation under this Section by purchasing insurance coverage.2.
    
    If Motto dies while employed by Meridian or while receiving the
Disability payments described in Section 1 above, Meridian shall pay $1 million to
the designated beneficiaries of Motto or, if none, to Mottos estate, reduced by
the gross amount of any payments made as Disability compensation pursuant to
Section 1 above and also reduced by any other insurance proceeds on Mottos life
received by Mottos estate or beneficiaries from any policies of life insurance
maintained by Meridian except for the proceeds of any group life insurance
maintained by Meridian for its employees.3.
    
    Meridian shall maintain health insurance coverage for Motto and his
spouse and the survivor of them for a period of five years after Mottos employment
with Meridian ends because of Mottos death or Disability. The health insurance
coverage shall be at levels comparable for executives in Mottos position at the
time that Mottos employment with Meridian has ended as determined by Meridian.
This shall satisfy Meridians obligation to provide continuation coverage to Motto
and his spouse under Section 4980B of the Internal Revenue Code of 1986.4.
    
    Motto or, after his death, his estate or heirs, shall have the right to
cause Meridian, on three separate occasions after September 30, 2003, to register
for public sale under the Securities Act of 1933 those shares of Meridian Common
Stock beneficially owned by Motto during his lifetime or at his death which may
not, at the time of request, be publicly sold without registration. The right to
request such registration shall end five years after Mottos death. This
registration right is conditioned upon Meridian being able to utilize the SECs
short-form registration statement, Form S-3, or its equivalent. Meridian shall
bear all costs of the registration except brokerage commissions which shall be the
responsibility of the seller.
