                         W I T N E S E T H

     Pursuant to that certain Stock Purchase  Agreement dated May 31, 1996,
(the  "Purchase  Agreement"), Buyer has acquired  the  outstanding  capital
stock of AME.  Capitalized terms used herein unless otherwise defined shall
have  the  meaning ascribed  to  such  terms  in  the  Purchase  Agreement.
Pursuant to Section 9 of the Purchase Agreement, the Sellers have agreed to
indemnify Buyer  and  AME and have agreed that the funds deposited pursuant
to this Escrow Agreement  shall  secure the indemnification obligations and
also secure the obligation to return part of the Purchase Price if required
by Section 1.7 of the Purchase Agreement.

     Therefore, pursuant to the Purchase  Agreement and in consideration of
the mutual covenants hereinafter contained,  the  parties  hereby  agree as
follows:

     SECTION 1.     On  even  date  herewith  and  upon  the Closing of the
Purchase  Agreement,  Sellers have caused to be deposited with  the  Escrow
Agent  the sum of Two Million  Seven  Hundred  Thousand  ($2,700,000)  (the
"Escrow  Money").   The  Escrow  Money  shall  be  held by the Escrow Agent
hereunder  as  partial security for the performance by  Sellers   of  their
indemnification  obligations  set  forth  in  Section  9.2  of the Purchase
Agreement  and/or  to  pay  Buyer  all  or  any part of any Purchase  Price
reduction as provided in Section 1.7 of the Purchase  Agreement, subject to
the terms and conditions hereof.

     SECTION 2.     In  the  event  the Purchase Price shall  be  decreased
under the provisions of Section 1.7,  the  amount of such decrease shall be
paid  by the Escrow Agent to the Buyer out of  the  Escrow  Money  and  any
interest, dividends and investment results thereon, provided, however, that
if payment  by  the  Escrow  Agent  to Buyer would reduce the amount of the
Escrow Money held under this Escrow Agreement  to the greater of $2,350,000
or  the value of all Claims (as herein defined) filed  against  the  Escrow
Money  by  Buyer or AME, then the Escrow Agent shall distribute to Buyer an
amount  of  the   Escrow  Money,  together  with  interest,  dividends  and
investment results  thereon, as shall not reduce the Escrow Money below the
greater of such amounts.   If  the  entire amount of the decreased Purchase
Price is not paid by the Escrow Agent to the Buyer out of the Escrow Money,
the remaining decreased Purchase Price  shall  be  paid  by  the Sellers to
Buyer in proportion to each Seller's share of the Purchase Price  allocated
under  SCHEDULE  1.3  of  the  Purchase  Agreement.  The Escrow Agent shall
disburse any decreased Purchase Price under this Section and Section 1.7 of
the  Purchase  Agreement  to  Buyer  either  (i)  upon  the  joint  written
instructions  of Buyer and Sellers or (ii) written  instructions  of  Buyer
which shall have  appended  a  copy of a letter or other written memorandum
from the Buyer, or in the event  of  a dispute in regard thereto, a written
memorandum from Coopers & Lybrand, L.L.P.,  in  the  event  of  a  dispute,
stating that there has been a Purchase Price reduction under the provisions
of  Section  1.7  of the Purchase Agreement and the amount of such Purchase
Price reduction.  Sellers  shall  not  be entitled to file any documents or
take any other action which would prevent  the Escrow Agent from paying any
decreased Purchase Price to Buyer pursuant to  the  written instructions of
Buyer  (or  Coopers  & Lybrand, L.L.P., in the event of  a  dispute).   Any
remaining portion of the Escrow Money after any distribution thereof to the
Buyer as a result of the decreased Purchase Price shall continue to be held
under the provisions of this Escrow Agreement and distributed in accordance
with the other provisions of this Escrow Agreement.

     SECTION 3.     The  Escrow  Money  and  any  interest,  dividends  and
investment  results  thereon  shall  be  held  by  the Escrow Agent for the
account of the Sellers, subject to written instruction  signed  jointly  by
the Buyer and Sellers or as otherwise provided herein.

     SECTION 4.     (a)  At  anytime  on or prior to the Escrow Termination
Date, as hereafter defined, with respect  to the Escrow Money, Buyer or AME
may give written notice (the "Initial Notice")  to  Sellers  and the Escrow
Agent of a claim (a "Claim") for indemnification resulting from any Damages
(as defined in the Purchase Agreement) suffered, sustained or  incurred  by
Buyer  or AME or that may reasonably be expected to be suffered by Buyer or
AME as a  result  of  any  matters  made  the subject of Section 9.2 of the
Purchase   Agreement  or  otherwise  arising  out   of   the   transactions
contemplated  by  and  made  the subject of the Purchase Agreement.  If the
Sellers dispute such Claim, the  Sellers shall send written notice to Buyer
and the Escrow Agent that such Claim is disputed within ten (10) days after
Sellers  are  deemed  to  have received  the  Initial  Notice  (a  "Counter
Notice").  Thereafter, except  as provided in the next sentence, the Escrow
Agent shall not deliver any of the  Escrow  Money or interest, dividends or
investment results thereon made the subject of  the Claim to the Buyer, AME
or Sellers except upon joint written instructions  of  the  Buyer,  AME and
Sellers.   As  an alternative to joint written instructions, Buyer, AME  or
Sellers may give  a  notice  (a  "Claim Notice") to the other party and the
Escrow Agent to the effect that a  Claim on all or part of the Escrow Money
(and accrued interest, dividends and investment results) has been resolved,
which notice shall set forth the amount  of  the  Claim  to be delivered to
Buyer, AME or Sellers, if any, and shall have appended a copy of a judicial
order,  judgment  or  decree  which  evidences a resolution of  the  Claim,
including a certification that neither  party  has  filed an appeal or that
any appeal which has been filed has been finally resolved.

                    (b)  Upon  receipt  of  the  Claim  Notice   with   all
necessary  attachments,  or upon receipt of joint written instructions, the
Escrow Agent shall promptly deliver to Buyer, AME or Sellers the amount due
either as set forth in the  Claim  Notice, if any, or the amounts set forth
in the joint written instructions.

                    (c)  Buyer or AME  may  file  Claims on both the Escrow
Money  and  any  interest,  dividends or investment results  thereon,  less
disbursement made of net income under Section 5 hereof.  If a Claim on less
than all of the Escrow Money  and  any  interest,  dividends and investment
results thereon is filed and all or any part of such  Claim  is  ultimately
paid to Buyer or AME, then, in addition to the amount of the Claim required
to be paid to Buyer or AME as a result of joint written instructions  or  a
Claim  Notice,  the  Escrow  Agent shall pay to Buyer, out of any remaining
Escrow Money and any interest, dividends and investment results thereon, an
amount of interest, dividends and investment results equal to the interest,
dividends and investment results  allocable  to  the  amount  of  the Claim
actually paid to the Buyer or AME from the date of the Initial Notice until
the  date all or any part of the Claim is paid to Buyer, less disbursements
made of net income under Section 5 hereof.

                    (d)  With  respect  to  all  amounts held in the Escrow
Account (and the income earned thereon), the  Escrow Termination Date shall
be the earlier of:

     (i)  May 31, 1998, or

     (ii) the date the Escrow Agent no longer holds any funds.

On  the  Escrow  Termination  Date,  the  Escrow Agent  shall  deliver  any
remaining  Escrow  Money,  including any accrued  interest,  dividends  and
investment results thereon,  less  disbursements  of  net income made under
Section 5 hereof, to the Representative, unless an Initial  Notice,  Claim,
or  Claim  Notice  is  pending,  in  any of which cases the amount claimed,
together with interest, dividends and  investment  results  on  the  amount
claimed from the date of the Initial Notice to the Escrow Termination Date,
shall  be  retained  by the Escrow Agent until a resolution of such pending
Claims.  Upon final resolution  of  the pending Claims and disbursements of
the amounts retained by the Escrow Agent  in  accordance with Claim Notices
or joint written instructions, this Escrow Agreement  shall terminate.  All
funds distributed by Escrow Agent to Sellers hereunder shall be distributed
to  the Representative for the benefit of the Sellers.   It  shall  be  the
responsibility  of  the  Representative  to  distribute  to each Seller his
portion of the funds distributed from the Escrow Account in accordance with
the Purchase Price allocation in SCHEDULE 1.3 of the Purchase Agreement.

                    (e)  The  Representative  of the Sellers  appointed  in
Section 24 of the Purchase Agreement is authorized  (i) to take all actions
permitted  hereunder by the Sellers, including joint instructions,  Counter
Notices, and  Claim  Notices  on  behalf  of the Sellers, (ii) to agree to,
dispute  or   settle and compromise any Claim,  Counter  Notice  and  Claim
Notice given hereunder  for  and on behalf of the Sellers, (iii) to receive
and  respond to any notice or other  communication  given  to  the  Sellers
hereunder  and  (iv)  to  receive  all  payments  on  behalf of the Sellers
pursuant to this Escrow Agreement.  The Escrow Agent, Buyer  and  AME shall
be  fully  protected in dealing exclusively with the Representative as  the
authorized agent  of  the  Sellers and the Sellers shall indemnify and hold
harmless the Escrow Agent, Buyer  and AME from any liability arising out of
or in connection with the authorization  herein  granted the Representative
to act for and on behalf of the Sellers.

     SECTION 5.     The Escrow Agent shall reinvest any interest, dividends
and  investment  results  earned on the Escrow Money.   For  tax  purposes,
interest, dividends and investment results earned on the Escrow Money shall
be taxed to the Sellers in  proportion to their share of the Purchase Price
as shown on SCHEDULE 1.3 of the  Purchase Agreement, except only so much of
same that is actually distributed  to  Buyer  during  any  tax period.  The
Sellers  shall  furnish the Escrow Agent with their taxpayer identification
numbers simultaneously  upon  execution  of  this  Escrow  Agreement  and a
statement from the Sellers that they are not subject to backup withholding.
The  Escrow Agent shall disburse to the Representative for distribution  to
the Sellers,  in  accordance  with  SCHEDULE 1.3 of the Purchase Agreement,
thirty percent (30%) of the net income  earned  during  each  calendar year
within thirty (30) days after the end of such year.

     SECTION 6.     All notices and other communications under  this Escrow
Agreement  shall  (a) be in writing (which shall include communications  by
facsimile), (b) be  (i)  sent by registered mail or certified mail, postage
prepaid, return receipt requested  or  by  facsimile,  or (ii) delivered by
hand,  (c)  be  given at the following respective addresses  and  facsimile

notices  of  a change of address or facsimile number shall  not  be  deemed
furnished until received.

     SECTION 7.     (a)  The  Escrow  Agent  shall not be under any duty to
give the property held hereunder any greater degree  of  care than it gives
its own similar property.

                    (b)  The  Escrow  Agent  may act in reliance  upon  any
instrument or signature believed to be genuine  and  may  assume  that  any
person  purporting  to  give  any writing, Initial Notice,  Counter-Notice,
Claim  Notice,  Claim,  advice  or   instruction  in  connection  with  the
provisions hereof has been duly authorized to do so.

                    (c)  The Escrow Agent  may  act  relative  hereto  upon
advice  of counsel in reference to any matter connected herewith, and shall
not be liable  for any acts or omissions unless caused by its negligence or
willful misconduct.

                    (d)  This  Escrow  Agreement sets forth exclusively the
duties of the Escrow Agent with respect  to  any  and all matters pertinent
hereto and no implied duties or obligations shall be  read into this Escrow
Agreement against the Escrow Agent.

                    (e)  The Escrow Agent makes no representation as to the
validity,  value,  genuineness  or  the collectibility of any  security  or
document, or instrument or property held or delivered to it.

                    (f)  Buyer and Sellers agree that they shall be equally
responsible for the payment of all reasonable  expenses,  disbursements and
advances incurred or made by the Escrow Agent in performance of such duties
hereunder,  including  reasonable fees, expenses and disbursements  of  its
counsel.  The Sellers' share  of  any  such fees and expenses of the Escrow
Agent  may be withheld and paid from the  Escrow  Money.   The  immediately
preceding  sentence  survives,  despite  any  termination  of  this  Escrow
Agreement or the resignation or removal of the Escrow Agent.

                    (g)  The  Escrow  Agent does not have and will not have
any interest in any of the Escrow Money  deposited or held hereunder but is
serving only as escrow holder and having only possession thereof.

                    (h)  All Escrow Money  received  by  the  Escrow  Agent
shall  be  invested and reinvested by the Escrow Agent in one year treasury
notes which  may  be  purchased through SouthTrust Securities, Inc., except
the Escrow Agent may hold a sufficient amount in a money market fund (which
may include a money market  fund  of  the Escrow Agent or its affiliate) to
meet anticipated distributions.

                    (i)  In  the  event  the   Escrow   Agent   before  the
termination  of  the  escrow  created by this Escrow Agreement receives  or
becomes aware of conflicting demands  or claims with respect to this escrow
or  the  rights of any of the parties hereto,  or  any  funds,  securities,
property or documents deposited herein or affected hereby, the Escrow Agent
shall have  the  right  to  discontinue any or all further acts on its part
until such conflict is resolved  to  its  satisfaction.   The  Escrow Agent
shall have the further right but not the obligation to commence  or  defend
any action or proceedings for the determination of such conflict including,
but   without   limiting  the  generality  of  the  foregoing,  a  suit  in
interpleader brought  by  the  Escrow Agent.  In the event the Escrow Agent
files  a  suit  in interpleader, and  delivers  to  the  court  all  funds,
securities, property  or  documents  then  in  deposit  hereunder, it shall
thereupon be fully released and discharged from all further  obligations to
perform  any  and all duties or obligations imposed upon it by this  Escrow
Agreement.  Buyer  and Sellers agree that they shall be equally responsible
for the payment of all  costs,  damages,  judgments and expenses, including
reasonable attorneys' fees, suffered or incurred  by  the  Escrow  Agent in
connection with or arising out of its escrow (except those caused by Escrow
Agent's  own  negligence or willful misconduct).   However, as between  the
Buyer and the Sellers,  the  nonprevailing  party  with  respect to a Claim
shall  be  required  to pay the costs and expenses of the prevailing  party
including the prevailing  party's  share  of  all of the costs, damages and
expenses of the Escrow Agent, if any.

                    (j)  The Escrow Agent shall not be liable for any error
of judgment or for any act done or omitted by it  in  good  faith,  or  for
anything  which it may in good faith do or refrain from doing in connection
herewith; nor  shall  the  Escrow  Agent  be liable if, in the event of any
dispute or question as to its duties or obligations  hereunder,  it acts in
accordance  with  written  opinion  of its legal counsel, which may include
attorneys who are members of or who are  employed by the Escrow Agent.  The
Escrow Agent is authorized to act upon any  document  believed  by it to be
genuine and to be signed by the proper party or parties, and will  incur no
liability in so acting.

     SECTION 8.     (a)  This  Escrow  Agreement and the Purchase Agreement
constitute the entire understanding among  the  parties  in connection with
the  subject  matter  hereof,  and no waiver or modification of  the  terms
hereof shall be valid unless in  writing  signed by the party to be charged
and only to the extent therein set forth.

                    (b)  This Escrow Agreement  shall  be  governed by, and
construed  in accordance with, the internal substantive laws  and  not  the
choice of laws rules of the State of Alabama.

                    (c)  This  Escrow  Agreement  shall be binding upon and
inure  to  the  benefit  of  the  parties  hereto, their respective  heirs,
administrators, executors, successors and assigns.

                    (d)  This  Escrow Agreement  may  be  executed  in  any
number of counterparts, each of  which  shall be deemed an original of this
Escrow Agreement and all of which taken together  shall  constitute one and
the same instrument.

                     (e)  If one or more provisions of this Escrow Agreement
are held to be unenforceable under applicable law, such provision  shall be
excluded  from  this  Escrow  Agreement  and  the  balance  of  this Escrow
Agreement shall be enforceable in accordance with its terms.

     IN  WITNESS  WHEREOF,  each  of  the parties hereto has executed  this
Escrow Agreement the day and year first above written.
