<PAGE>   3
notices respecting the Obligation; and agrees that maturity of the Obligation
and any part thereof may be accelerated, extended or renewed one or more times
by Bank in its discretion, without notice to Pledgor. Pledgor waives any right
to require that any action be brought against any other person or to require

account. Pledgor further waives any right of subrogation or to enforce any right
of action against any other Pledgor until the Obligation is paid in full.

   L. WAIVER OF NOTICE FOR IMMEDIATE WRIT OF POSSESSION. Pledgor hereby
acknowledges that the indebtedness arises out of a 'commercial transaction" as
that term is defined in the O.C.G.A. Sec. 44-12-260(1) concerning foreclosure of
mortgages on personally, and agrees that if a default has occurred and is
continuing, Bank shall have the right to an immediate writ of possession without
notice of hearing, and Pledgor hereby knowingly and intelligently waives any and
all rights it may have to any notice and posting of a bond prior to seizure by
Bank, its transferees, assigns or successors in interest of the Collateral or
any portion thereof. The foregoing is intended by Pledgor as a "waiver" as that
term is defined in the O.C.G.A. Sec 44-14-260 (3) relating to foreclosure of
mortgages on personalty.

   M. ADDITIONAL PROVISIONS. If one or more Riders to this Agreement are
executed by Pledgor, the covenants and provisions of each such Rider shall be
incorporated by reference into this Agreement.

      RULE 144 RIDER: The Collateral is comprised in whole or in part of control
and/or restricted securities, which shall be subject to the additional terms and
provisions described on the Rule 144 Rider attached hereto and made a part
hereof for all purposes.

6.   MAINTENANCE OF COLLATERAL.

   A. MAINTENANCE OF COLLATERAL. At all times during the term of the Agreement,
Pledgor agrees to maintain as security for the Obligation Collateral of a type
described on Schedule I with an Adjusted Collateral Value (as determined herein)
in excess of the unpaid principal balance of the Obligation. The Adjusted
Collateral Value shall be determined by multiplying the Collateral Value As
defined in subparagraph B below) by the Margin Call Percentage shown on Schedule
I for the type of Collateral securing the Obligation.

      No advance requested by Pledgor shall be made to Pledgor if the sum of (i)
the outstanding principal balance of the Obligation plus (ii) the amount of the
advance requested, equals or exceeds the sum of the amounts determined by
multiplying the Collateral Value by the Original Advance Percentage for each
type of Collateral securing the Obligation.

   B. VALUE OF COLLATERAL. The "Collateral Value" of Collateral shall be
determined at any given time as follows:

     i. If stock, the Collateral Value shall be determined by multiplying (i)
the per share price of such stock at the most recent close of trading on a
trading exchange for such stock, times (ii) the number of shares of such stock
held by Bank as Collateral. In the event that stock held as Collateral is not
traded on an exchange, the Collateral Value of such stock shall be determined by
obtaining the quoted value of such stock from a reputable brokerage firm
selected by Bank. If no such quote is available, the value will be determined by
Bank in its sole discretion.

     ii. If a mutual fund, the Collateral Value shall be determined by
multiplying (i) the most recent per share asset value of such mutual fund
obtained from the Wall Street Journal, times (ii) the number of shares of such
mutual fund held by Bank as Collateral. In the event that such net asset value
is not available in the Wall Street Journal, the Collateral Value shall be the
value quoted to Bank by a reputable brokerage firm selected by Bank.

     iii. If corporate bonds, the Collateral Value shall be determined from the
most recent closing price for such bonds obtained from the Wall Street Journal.
If such closing price is not available in the Wall Street Journal, the
Collateral Value shall be the value quoted to Bank by a reputable brokerage firm
selected by Bank.

     iv. If government or agency obligations or bonds, the Collateral Value
shall be determined from the most recent closing bid price for such bonds
obtained from the Wall Street Journal. If such closing bid price is not
available in the Wall Street Journal, the Collateral Value shall be the value
quoted to Bank by a reputable brokerage firm selected by Bank.

     v. If other than stock, mutual funds, corporate bonds, or government or
agency obligations or bonds, the Collateral Value shall be determined by the
Bank in its sole discretion.

   C. BREACH OF COLLATERAL MAINTENANCE. Pledgor agrees that the failure to
maintain Collateral with an Adjusted Collateral Value as set forth above shall
constitute an Event of Default under this Agreement. In such event, the Pledgor
shall have two business days from the date Pledgor is notified by Bank (in
writing or orally) of such noncompliance, or such notice is otherwise delivered
to Pledgor, to either pledge additional Collateral satisfactory to Bank, in its
sole discretion, or reduce the unpaid principal balance of the Obligations such
that, in either case, the unpaid principal balance of the Obligation is less
than the sum of the amounts determined by multiplying the Collateral Value by
the Original Advance Percentage shown on Schedule I for each type of Collateral
securing the Obligation. Any reduction in unpaid principal of the Obligation
shall not affect or reduce any future principal payments due except to the
extent such reductions are applied in accordance with the documents evidencing
or securing the Obligation In the event Pledgor fails to comply with the terms
hereof, Bank may, without any further notice of any kind, exercise any of the
following rights and remedies, at Bank's option:

   i.  The rights and remedies set out in Section 8.B. of this Agreement,
including without limitation the right to accelerate the Obligation and
liquidate the Collateral.

   ii. Sell all or any part of the Collateral and apply the proceeds of such
sale to the Obligation to bring the Obligation back into compliance ( that is,
to reduce the unpaid principal of the Obligation such that the unpaid principal
of the Obligation is less than the sum of the amounts determined by multiplying
the Collateral Value by the Original Advance Percentage shown on Schedule I for
each type of Collateral securing the Obligation).

If an Event of Default exists hereunder and the Collateral is declining in value
or threatens to decline speedily in value, Bank shall have no obligation to
notify Pledgor of the failure to maintain Collateral with an Adjusted Collateral
Value as set forth in subparagraph A above or to provide Pledgor with an
opportunity to cure such noncompliance, and in such case Pledgor agrees that
Bank may immediately at Bank's sole option (i) declare amounts due under the
Obligation to be immediately due and payable, and/or (ii) sell all or any part
of the Collateral and apply the proceeds of such Collateral to the Obligation.

   D. SALE OR SUBSTITUTION OF COLLATERAL. If no Event of Default has occurred
under this Agreement or would result from such action, Pledgor may (i) sell,
trade, or withdraw any part of the Collateral; or (ii) substitute new Collateral
for existing Collateral, provided that, in either event, the new Collateral
shall be acceptable to Bank in its sole discretion and the unpaid principal
balance of the Obligation shall be less than the sum of the amounts determined
by multiplying the Collateral Value by the Original Advance Percentage for each
type of Collateral securing the Obligation.

which is convertible into any other instrument or investment security or a

final conversion date to make such conversion possible.

of the following rights and remedies, at Bank's option:

and terminate.

or for the credit of the account of Pledgor or any guarantor or indorser of
Pledgor's Obligation.

Pledgor specifically understands and agrees that any sale by Bank of all or part
of the Collateral pursuant to the terms of this Agreement may be effected by
Bank at times and in manners which could result in the proceeds of such sale as
being significantly and materially less than might have been received if such
sale had occurred at different times or in different manners, and Pledgor hereby
releases Bank and its officers and representatives from and against any and all
obligations and liabilities arising out of or related to the timing or manner of
any such sale.

If, in the opinion of Bank, there is any question that a public sale or
distribution of any Collateral will violate any state or federal securities law,

registration under federal securities law, and any such sale made in good faith
by Bank shall be deemed "commercially reasonable."
