collateral security for the Obligations. Any sums paid upon or in respect of the
Pledged Stock (or any other  Collateral)  upon the liquidation or dissolution of
the TFCI  and/or  AVest,  as the case may be,  shall be paid over to the Secured
Party to be held by it  hereunder  as  additional  collateral  security  for the
Obligations,  and in case any  distribution  of  capital  shall be made on or in
respect of the Pledged Stock (or any other  Collateral) or any property (cash or
non-cash) shall be distributed upon or with respect to the Pledged Stock (or any
other Collateral)  pursuant to the  recapitalization  or reclassification of the
capital of the Borrower or pursuant to the reorganization  thereof, the property
so distributed shall be delivered to the Secured Party to be held by the Secured
Party hereunder as additional  collateral  security for the Obligations.  If any
sums of money or property so paid or distributed in respect of the Pledged Stock
(or any other Collateral)  shall be received by the Pledgor,  the Pledgor shall,
until such money or property is paid or  delivered  to the Secured  Party,  hold
such money or  property in trust for the Secured  Party,  segregated  from other
funds of the Pledgor, as additional  collateral security for the Obligations and
so immediately deliver it to the Secured Party.

     (b) Without the prior  written  consent of the Secured  Party,  the Pledgor
will not directly or indirectly (i) vote to enable,  or take any other action to
permit,  TFCI and/or AVest,  as the case may be, to hereafter issue any stock or
other  equity  securities  of  any  nature  or to  issue  any  other  securities

Pledgor will defend the right, title and interest of the Secured Party in and to

security interest in any and all Collateral, or may otherwise reasonably request
for the  purposes of obtaining or  preserving  the full  benefits of this Pledge
Agreement and of any and all of the rights,  remedies and powers herein granted.
If any amount payable under or in connection with any of the Collateral shall be
or become  evidenced by any promissory  note, other instrument or chattel 


                                      -6-


paper, such note,  instrument or chattel paper shall be immediately delivered to
the Secured Party, duly endorsed in a manner  satisfactory to the Secured Party,
to be held as additional collateral pursuant to this Pledge Agreement.

any and all liabilities  with respect to, or resulting from any delay in paying,
any and all  stamp,  excise,  sales or  other  taxes  which  may be  payable  or
determined to be payable with respect to any of the  Collateral or in connection
with  any of the  transactions  contemplated  by this  Pledge  Agreement  or the
exercise  by  the  Secured  Party  of  any of its  rights,  remedies  or  powers
hereunder.

     6. VOTING RIGHTS; DIVIDENDS. Unless an Event of Default shall have occurred
and be  continuing,  the Pledgor  shall be  permitted to exercise all voting and
corporate  rights with respect to the Pledged  Stock,  PROVIDED,  HOWEVER,  that
Pledgor  covenants to the Secured  Party that no vote shall be cast or corporate
right  exercised or other action taken by Pledgor which,  in the Secured Party's
reasonable judgment,  would impair the Collateral or which would be inconsistent
with or result in any  violation of any provision of any agreement or instrument
relating to any Obligation or any agreement or instrument  between Secured Party
and Borrower or from Borrower to Secured Party, including without limitation the
Credit Agreement, this Agreement, or any other Financing Document (as defined in
the Credit  Agreement).  The Secured  Party,  if an Event of Default  shall have
occurred  or be  continuing,  shall  have  the  right  to  receive  and  hold as
additional  collateral any dividends or other distributions on the Pledged Stock
or other  Collateral  and, in the event that the Pledgor  shall be  delivered or
otherwise  have received (or be entitled to receive) any such dividends or other
distributions,  Pledgor shall hold same in trust and immediately  turn over same
to the Secured Party who may hold same as additional collateral.

     7. RIGHTS OF THE SECURED PARTY. (a) If any Event of Default shall occur and

nominee may exercise (i) all voting,  corporate and any other rights  pertaining

and/or (ii) any and all rights of  conversion,  exchange,  subscription  and any
other  rights,  privileges  or options  pertaining to the Pledged Stock (and any
other  applicable   Collateral)  as  if  it  were  the  absolute  owner  thereof
(including,  without limitation, the right to exchange at its discretion any and
all of the Pledged Stock (and any other applicable  Collateral) upon the merger,
consolidation,  reorganization,  recapitalization or other fundamental change in
the corporate  structure of TFCI and/or  AVest,  as the case may be, or upon the
exercise by the Pledgor or the Secured  Party of any right,  privilege or option
pertaining  to such  shares  of the  Pledged  Stock  (and any  other  applicable
Collateral),  and in connection therewith,  the right to deposit and 


                                      -7-


deliver any and all of the Pledged Stock (and any other  applicable  Collateral)
with any committee,  depository,  transfer agent,  registrar or other designated
agency  upon  such  terms  and  conditions  as it may  determine),  all  without
liability  to the  Pledgor,  but the  Secured  Party  shall  have no duty to the
Pledgor to exercise any of the foregoing rights, privileges or options and shall
not be responsible for any failure to do so or delay in so doing.

     (b) The  rights of the  Secured  Party  under this  Agreement  shall not be
conditioned or contingent  upon the pursuit by the Secured Party of any right or
remedy  against the Pledgor or against any other  Person or against any security
or collateral. The Secured Party shall have no obligation or duty (and shall not
be liable for any failure) to demand,  collect, apply or realize upon all or any
part of the  Collateral  or for any delay in doing so, to  collect or to sell or
otherwise dispose of any Collateral  (whether upon the request of the Pledgor or
any  other  Person or  otherwise  and  whether  or not an Event of  Default  has
occurred or the value of the Collateral  has (or may) increase or decrease),  to
advise  the  Pledgor of any  actual or  anticipated  changes in the value of the
Collateral, to act as an investment advisor or insurer of any of the Collateral,
to preserve rights against prior parties,  to protect Collateral  (except,  with
respect to Collateral in its possession, as specifically set forth in Section 12
below), to take any other action whatsoever with regard to the Collateral or any
part  thereof,  or to seek  payment  from any  particular  source,  and any such
obligation  or  duty  is  hereby  waived  to the  fullest  extent  permitted  by
applicable law.

     8.  REMEDIES.  If an Event of Default  shall occur and be  continuing,  the
Secured Party may exercise, in addition to all other rights, remedies and powers
granted in this Pledge  Agreement or in any other  instrument or agreement,  all
rights, remedies, and powers whether as a secured party or otherwise,  under the
Code or other  applicable law. Without limiting the generality of the foregoing,
the Secured Party,  without the need for demand of payment or other  performance
or other  demand,  presentment,  protest,  advertisement  or  notice of any kind
(except any notice  required by law  referred to below) to or upon the  Pledgor,
TFCI, AVest or any other Person (all of which demands, defenses,  advertisements
and  notices  are  hereby  waived),  may at any and all times  demand,  sue for,
collect, receive,  appropriate and/or realize upon any or all of the Collateral,
and/or make any  settlement  or compromise  which the Secured  Party  reasonably
deems desirable with respect to any or all Collateral, and/or sell, assign, give
option or options to  purchase or  otherwise  dispose of and deliver any and all
the Collateral (or contract to do any of the foregoing),  in one or more parcels
at public or  private  sale or sales,  in the  over-the-counter  market,  at any
exchange,  broker's  board or office of the Secured Party or elsewhere upon such
terms and  conditions as it may deem advisable and at such prices as it may deem
best,  for cash or on credit or for future  delivery  without  assumption of any
credit risk. The Secured Party shall have the right upon any such public sale or
sales, and, to the extent permitted by law, upon any such private sale or sales,
to purchase the whole or any part of the  Collateral so sold,  free of any right
or equity of redemption in the Pledgor, which right or equity is, to the fullest
extent  permitted under  applicable law, hereby waived.  The Secured 


                                      -8-


Party  shall have the right to apply any  Proceeds  from time to time held by it
and the net proceeds of any such collection,  recovery, receipt,  appropriation,
realization or sale,  after deducting all reasonable costs and expenses of every
kind incurred in respect thereof or incidental to the care or safekeeping by the
Secured Party (or any agent or  representative  of the Secured  Party) of any of
the Collateral or in any way relating to the Collateral or the rights,  remedies
or  powers  of the  Secured  Party  hereunder,  including,  without  limitation,
reasonable attorneys' fees and disbursements of counsel to the Secured Party, to
the payment of any and all of the Obligations (whether matured or unmatured), in
such  order and  manner as the  Secured  Party may  elect,  and only  after such
application  and after the  payment  by the  Secured  Party of any other  amount
required  by any  provision  of  law,  including,  without  limitation,  Section
9-504(1)(c) of the Code, need the Secured Party account for the surplus, if any,
to the Pledgor.  To the extent  permitted by applicable  law, the Pledgor waives
all claims, damages and demands it may acquire against the Secured Party arising
out of the  exercise  by the  Secured  Party of any  rights,  remedies or powers
hereunder.  If any notice of a proposed sale or other  disposition of Collateral
shall be required by law, ten (10)  calendar  days prior  written  notice of the
time and place of any public sale or of the time after which any private sale or
other intended disposition is to be made shall be deemed reasonable. The Pledgor
further  waives and agrees not to assert any rights or  privileges  which it may
acquire under  Section 9-112 of the Code.  The Pledgor shall remain fully liable
for any  deficiency  if the  proceeds  of any sale or other  disposition  or any
application of the Collateral are  insufficient  to pay the  Obligations and the
costs and expenses of the Secured  Party.  Nothing  contained in this  Agreement
shall be  interpreted or construed so as to require the Secured Party to realize
upon the Collateral prior to attempting to collect any of the  Obligations,  and
the Secured Party may exercise all of its various rights, remedies and powers in
such order and manner as Secured Party, in its discretion, shall deem advisable.

     9.  REGISTRATION  RIGHTS;  PRIVATE  SALES.  (a) If the Secured  Party shall
determine  to  exercise  its right to sell any or all of the  Pledged  Stock (or
other  applicable  Collateral)  pursuant  to  Section  8  hereof,  and if in the
reasonable  judgment of the Secured  Party it is  necessary or advisable to have
the Pledged Stock (or other applicable  Collateral),  or any portion thereof, to
be sold in a transaction which is required to be registered under the provisions
of the Securities Act of 1933, as amended (the  "Securities  Act"),  the Pledgor
will cause TFCI and/or  AVest,  as the case may be, to (i) execute and  deliver,
and cause the  directors  and officers of the to execute and  deliver,  all such
instruments and documents, and do or cause to be done all such other acts as may
be, in the opinion of the Secured Party,  necessary or advisable to register the
Pledged Stock (and, if requested by the Secured Party,  such other  Collateral),
or that portion thereof to be sold,  under the provisions of the Securities Act,
(ii) use Pledgor's  best efforts to cause the  registration  statement  relating
thereto to become  effective  and to remain  effective  for a period of one year
from  the  date of the  first  public  offering  of the  Pledged  Stock  (and if
requested by the Secured Party,  such other  Collateral) or that portion thereof
to be sold,  and  (iii)  make  all  amendments  thereto  and/or  to the  related
prospectus  which,  in the  opinion  of the  


                                      -9-


Secured  Party,  are  necessary  or  advisable,   all  in  conformity  with  the
requirements  of the  Securities  Act  and  the  rules  and  regulations  of the
Securities and Exchange  Commission  applicable  thereto.  The Pledgor agrees to
cause TFCI and/or  AVest,  as the case may be, to comply with the  provisions of
the securities or "Blue Sky" laws of any and all jurisdictions which the Secured
Party shall designate and to make available to its security holders,  as soon as
practicable,  an earnings statement which will satisfy the provisions of Section
11(a) of the Securities Act.

     (b) The Pledgor recognizes that the Secured Party may be unable to effect a
public sale of any or all the Pledged Stock (or other applicable Collateral), by
reasons of certain  prohibitions  contained in the Securities Act and applicable
state   securities  laws  or  otherwise   (including   without   limitation  the
impracticability  of such a public sale due to the value of the Pledged Stock or
otherwise),  and may be compelled to resort to one or more private sales thereof
to a restricted group of purchasers which will be obliged to agree,  among other
things,  to acquire such securities for their own account for investment and not
with a view to the distribution or resale thereof.  The Pledgor acknowledges and
agrees  that any such  private  sale may result in prices  and other  terms less
favorable  than if such  sale  were a  public  sale  and,  notwithstanding  such
circumstances,  agrees that any such  private  sale shall be deemed to have been
made in a commercially  reasonable  manner.  The Secured Party shall be under no
obligation to delay a sale of any of the Pledged Stock (or other Collateral) for
the period of time necessary to permit the Borrower to register such  securities
for public sale under the Securities Act, or under  applicable  state securities
laws, even if the Borrower would agree to do so.

     (c) The Pledgor further agrees to use Pledgor's best efforts to do or cause
to be done all such other acts as may be  necessary to make any sale or sales of
all or any portion of the Pledged Stock (or other  Collateral)  pursuant to this
Pledge  Agreement  valid and  binding and in  compliance  with any and all other
applicable  requirements of law. The Pledgor further agrees that a breach of any
of the covenants  contained in this Section 9 will cause  irreparable  injury to
the  Secured  Party,  that the Secured  Party has no  adequate  remedy at law in
respect of such  breach  and,  as a  consequence,  that each and every  covenant
contained  in this  Section  9 shall be  specifically  enforceable  against  the
Pledgor,  and the Pledgor  hereby  waives and agrees not to assert any  defenses
against  an action  for  specific  performance  of such  covenants  except for a
defense that no Event of Default has occurred.

     10. RIGHTS OF SUBROGATION,  CONTRIBUTION,  REIMBURSEMENT OR INDEMNITY.  The
Pledgor  shall not  enforce  any rights  that the  Pledgor  may at any time have
against  TFCI  and/or  AVest,  as the case may be,  any other  guarantor  or any
applicable  collateral,  including,  but not limited to, rights of  subrogation,
exoneration,  indemnity,  reimbursement  and contribution and whether arising by
operation  of law or  otherwise,  until all of the  Obligations  have been paid,
observed  


                                      -10-


and performed in full, except that this Section shall not apply to routine acts,
such as the  giving  of  notices  and the  filing  of  continuation  statements,
necessary to preserve any such rights.

     11.  CERTAIN  WAIVERS.  The  Pledgor  waives  (i)  diligence,  presentment,
protest,  demand for payment and notice of default or nonpayment to or upon TFCI
and/or AVest, as the case may be, or the Pledgor with respect to the Obligations
or any  obligations or liabilities of the Borrower to the Secured Party and (ii)
the benefit of any  marshalling  doctrine  with  respect to the Secured  Party's
exercise of its rights, remedies or powers hereunder or otherwise.

     12.  LIMITATION ON DUTIES  REGARDING  COLLATERAL.  The Secured Party's sole
duty with respect to the custody,  safekeeping  and  physical  preservation  and
protection of the Collateral in its possession,  under Section 9-207 of the Code
or  otherwise,  shall be to deal with it in the same manner as the Secured Party
deals with similar  securities  and  property  for its own account.  Neither the
Secured Party nor any of its  officers,  employees or agents shall be (i) liable
or  responsible  for any failure to demand,  collect or realize  upon any of the
Collateral  or for any  delay in doing so or for any  change in the value of any
Collateral  (whether  before  or after an Event of  Default)  or (ii)  under any
obligation  to sell or  otherwise  dispose of any  Collateral,  whether upon the
request of the Pledgor or otherwise.

     13. POWERS COUPLED WITH AN INTEREST. All authorizations and agencies herein
contained with respect to the Collateral are irrevocable and powers coupled with
an interest.

     14.  SEVERABILITY.   Any  provision  of  this  Pledge  Agreement  which  is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition  or  unenforceability  without
invalidating the remaining provisions hereof in such jurisdiction,  and any such
prohibition  or  unenforceability  in any  jurisdiction  shall not invalidate or
render unenforceable such provision in any other jurisdiction.

     15.  PARAGRAPH  HEADINGS.  The  paragraph  headings  used  in  this  Pledge
Agreement  are for  convenience  of  reference  only and  shall not  affect  the
construction hereof or be taken into consideration in the interpretation hereof.

     16. NO WAIVER; CUMULATIVE REMEDIES; WAIVERS AND AMENDMENTS.

          (a) The  Secured  Party  shall  not by any act  (except  by a  written
     instrument  executed and delivered by the Secured Party in accordance  with
     subparagraph (b) below), delay, indulgence, omission or otherwise be deemed
     to have waived any right,  remedy or power  hereunder or to have acquiesced
     in any  Event  of  Default.  No  failure  to  exercise,  nor any  delay  in
     exercising,  on the part of the Secured Party,  any right,  remedy or power
     shall  operate as a waiver  thereof.  No single or partial  exercise of any
     right,  remedy or power  hereunder  shall  preclude  any  other or  further
     exercise  thereof or the  exercise of any other right,  remedy or power.  A
     waiver by the Secured Party of any right,  remedy or power hereunder on 


                                      -11-


     any one occasion  shall not be  construed as a bar to any right,  remedy or
     power which the Secured Party would otherwise have on any future  occasion.
     The rights,  remedies and powers of the Secured  Party herein  provided are
     cumulative,  may be exercised  singly or concurrently and are not exclusive
     of any other rights,  remedies or powers  provided by applicable law or any
     other agreement,  instrument or other document.  Secured Party may exercise
     any or all such  rights,  remedies  and powers at any  time(s) in any order
     which Secured Party chooses.

          (b) None of the terms or  provisions  of this Pledge  Agreement may be
     amended,  waived,  supplemented  or otherwise  modified except by a written
     instrument executed and delivered by the party sought to be charged.

     17. SUCCESSORS AND ASSIGNS. This Pledge Agreement shall be binding upon the
successors, assigns, heirs and representatives of the Pledgor and shall inure to
the benefit of the Secured Party and its successors and assigns.

     18. NOTICES.  Notices by one party to the other shall be in writing and may
be given by mail, by overnight mail sent by Federal Express or other  nationally
recognized  overnight courier,  or delivery by hand,  addressed to such party at
the address set forth in the first  paragraph  hereof and shall be deemed  given
(a) in the case of mail,  four (4)  Business  Days after being  deposited in the
mail, first class postage  pre-paid,  (b) in the case of overnight mail, one (1)
Business Day after being sent by overnight mail, and (c) in the case of delivery
by hand,  when  delivered.  Either  party may change its address for delivery of
notices by written  notice to the other in the manner set forth in this  Section
18.

     19.  IRREVOCABLE  AUTHORIZATION  AND  INSTRUCTION TO BORROWER.  The Pledgor
hereby  irrevocably  authorizes  and instructs  each of TFCI and AVest to comply
with any  instruction  received  by it from the  Secured  Party,  on demand,  in
writing  that (a)  states  that an  Event of  Default  has  occurred  and (b) is
otherwise in  accordance  with the terms of this Pledge  Agreement,  without any
other or further instructions from the Pledgor, and the Pledgor agrees that TFCI
and AVest shall be fully protected in so complying.

     20. COSTS AND EXPENSES.  The Pledgor  hereby agrees to pay or reimburse the
Secured  Party,  on  demand,  for all  costs  and  expenses  (including  without
limitation all reasonable  attorneys' fees and  disbursements and the reasonable
fees and  disbursements of all other experts  including  without  limitation all
accountants  and  appraisers)  incurred by the Secured Party in connection  with
administrating,  preserving, defending, protecting, exercising or enforcing this
Pledge  Agreement  or any of its  rights,  remedies  and  powers  hereunder,  or
attempting to do any of the foregoing,  including  without  limitation all costs
and expenses  incurred in connection  with the exercise of any right,  remedy or
power with respect to the Collateral.


                                      -12-


     21.  INTEGRATION.  This Pledge  Agreement  represents  the agreement of the
Pledgor to the Secured  Party with  respect to the subject  matter  hereof,  and
there  are no  promises,  undertakings,  representations  or  warranties  by the
Secured Party  relative to the subject  matter hereof not expressly set forth or

RIGHTS AND  OBLIGATIONS  OF THE  PLEDGOR  UNDER THIS PLEDGE  AGREEMENT  SHALL BE
GOVERNED BY, AND CONSTRUED AND  INTERPRETED IN ACCORDANCE  WITH, THE LAWS OF THE

THE RIGHT THERETO IN ANY ACTION OR PROCEEDING OF ANY KIND,  ARISING UNDER OR OUT
OF, OR OTHERWISE RELATED TO OR CONNECTED WITH, THIS PLEDGE AGREEMENT.
