                          SECURITY AND PLEDGE AGREEMENT

     AGREEMENT,  dated  as of  April  28,  1995  by  and  between  Scott  Zecher
("Zecher") and Autolnfo, Inc., a Delaware corporation ("Auto").

     WHEREAS,  Zecher has on the date hereof delivered to Auto a promissory note
in the principal  amount of  $466,797.64,  a copy of which is annexed  hereto as
Exhibit A (the "Note"), evidencing a loan in the principal amount of $466,797.64
from Auto to Zecher in connection  with Zecher's  exercise of options to acquire
Auto Common Stock; and

     WHEREAS,  Zecher  has agreed to pledge his  216,799  shares of Auto  Common
Stock issuable in connection with the option exercise (the "Shares") as security
for the repayment of the debt evidenced by the Note.

     NOW, THEREFORE, the parties hereto agree as follows:

     1. Security Interest in Pledged Shares.

     (a)  Zecher  hereby  grants  to  Auto,  as  collateral   security  for  the
          performance of his obligations  under the Note, a security interest in
          the Shares and all profits,  dividends  and other  distributions  with
          respect   to  or  other   rights  in   connection   with  the   Shares
          (collectively, the "Collateral").

     (c)  Zecher hereby delivers transfers,  conveys and assigns to, and pledges
          and hypothecates with Auto the shares and certificate(s)  representing
          the Shares,  accompanied by signature  guaranteed  stock power(s) duly
          executed in blank in proper form for transfer.

     2. Sale of Security in Satisfaction of Note.

     In the event  Zecher  elects to repay the Note out of the  proceeds  of the
Shares he shall  advise  Auto to such  effect in  writing.  Upon such  event the
Shares  shall be delivered to Dreyer and Traub,  as escrow  agent  ("D&T").  D&T





shall deliver the Shares to such selling broker as Zecher shall designate,  upon
receipt in writing from such broker an undertaking  that the net proceeds of the
sale of the Shares will be  delivered to D&T, as escrow  agent.  Upon receipt of
such  proceeds,  D&T shall  deliver  to Auto a check in the amount of any unpaid
principal  and accrued  interest on the Note then due and payable plus any other
amount then due and owing from Zecher to Auto. The  remainder,  if any, shall be
paid by check to Zecher.

     3. Rights and Remedies of Auto.

     If at any time hereafter,  Zecher shall fail to make payment when due under
the Note (an "Event of Default") and such Event of Default shall  continue for a
period of fifteen days after written notice thereof to Zecher, then:

     3.1 Voting Dividends, etc.

     Auto shall have all voting and consensual  powers pertaining to the Shares.
In order to permit Auto to exercise such voting or other  powers,  Zecher shall,
upon the written  request of Auto, from time to time execute and deliver to Auto
appropriate proxies.

     3.2 Registration in Name of Auto.

     Auto shall have the right at any time and from time to time  thereafter  to
transfer  any of the Shares into its name or the name of a nominee or  nominees.
Nothing  contained  in this  Section 3.2 shall  deprive  Zecher of any rights of
redemption provided by law.

     3.3 Sale of Collateral.

     In addition to any other  rights and remedies  which Auto may have,  it may
immediately and without demand exercise any and all rights and remedies  granted
to a secured party upon the  occurrence of an Event of Default under the Uniform
Commercial Code.






     3.4 Duty with Respect to Collateral.

     The duty of Auto and D&T with respect to the Collateral  shall be solely to
use reasonable care in the physical custody and preservation  thereof,  and Auto
and D&T shall not be under any  obligation  to take any  action in regard to the
Collateral or any part thereof, except as provided herein.

     3.5 Application of Proceeds.

     Auto shall apply the purchase price or other moneys collected,  received or
held by it in respect  of the  Collateral  in the  following  order:  (a) to the
payment of all costs, expenses,  liabilities and advances,  including reasonable
attorneys' fees and  disbursements,  incurred or made by Auto in the protection,
exercise, or enforcement of its interests, rights, powers, or remedies hereunder
upon the  occurrence  of any Event of Default;  (b) to the payment of the unpaid
principal of and accrued  interest on the Note then due and payable;  (c) to the
payment of any other amounts due from Zecher to Auto; and (d) the remainder,  if
any, to Zecher.

     3.6 Return of Collateral.

     Auto shall return to Zecher all Collateral then held by it pursuant to this
Agreement and any transfer documents executed by Zecher with respect thereto, as
soon as there shall be no amounts  unpaid or  otherwise  owing to Auto under the
Note or this  Agreement.  The Collateral so returned shall not, as the result of
any  transaction  entered into or action taken by Auto,  be subject to any lien,
encumbrance,  attachment or other state of facts which result in any  diminution
of the title of Zecher therein, but shall otherwise be returned without recourse
upon or warranty by Auto.

     4. Miscellaneous.

     4.1 Auto Appointed Attorney-in-Fact.

     Zecher hereby  constitutes and appoints,  effective as of the occurrence of
an Event of Default and while the same is continuing,  Auto as  attorney-in-fact
for the purpose of carrying out the  provisions of this Agreement and taking any
action and executing any instrument,  including  without  limitation,  financing



statements  and  instruments  of  assignment in the ease of a sale of Collateral
upon  default,  which Auto may deem  necessary or advisable  to  accomplish  the
purposes hereof,  which appointment is irrevocable and coupled with an interest.
If  Zecher  shall  fail to do any act or  thing  which it has  covenanted  to do
hereunder,  Auto as  attorney-in-fact or in its own right, may (but shall not be
obligated to) do the same or cause it to be done.

     4.2 No Waiver, etc.

     No action  taken by Auto shall be deemed to  constitute a waiver by Auto of
compliance by Zecher with any representation,  warranty,  covenant, or agreement
contained in this Agreement. No course of dealing between the parties hereto and
no  failure or delay on the part of Auto in  exercising  any  right,  power,  or
privilege hereunder shall operate as a waiver thereof,  and no single or partial
exercise of any such right, power or privilege. The rights and remedies provided
in this  Agreement are  cumulative and are in addition to, and not exclusive of,
any other  rights or  remedies  provided  by law,  in  equity,  by  statute,  or
otherwise.  No notice to or demand on Zecher in any case shall entitle Zecher to
any other or  further  notice or demand in  similar  or other  circumstances  or
constitute a waiver of the rights of Auto to take any other or further action in
any  circumstances  without  notice  or  demand.  The  waiver of a breach of any
provision of this  Agreement  or of an Event of Default  shall not operate or be
construed as a waiver of any subsequent breach or Event of Default.

     4.3 Notices.

     All notices and other  communications  required  or  permitted  to be given
under this  Agreement  shall be in writing and shall be deemed to have been duly
given  if  delivered  personally  or  sent by  certified  mail,  return  receipt
requested,  postage prepaid, to the parties hereto as follows: to Zecher at 1341
Hudson  Road,  Teaneck,  New Jersey  07666;  to Auto at 255 West  Spring  Valley
Avenue,  Maywood,  New Jersey 07607, Attn:  Chairman;  with a copy to Dreyer and



Traub, 101 Park Avenue, New York, New York 10178, Attn: Kenneth S. Rose, Esq.

     4.4 Severability.

     The invalidity or unenforceability of any provision of this Agreement shall
not affect the validity or  enforceability of the remainder of this Agreement or
the reminder of such  provision.  If any provision of this Agreement is so broad
as to be unenforceable,  such provision shall be interpreted to be only so broad
as is enforceable.

     4.5 Section and Other Headings.

     The  section  and  other  headings  contained  in  this  Agreement  are for
reference  purposes only and shall not be deemed to be a part of this  Agreement
or to affect the meaning or interpretation of this Agreement.

     4.6 Execution in Counterparts.

     This Agreement may be executed in any number of counterparts, each of which
shall be deemed to be an original and all of which  together  shall be deemed to
be one and the same instrument.

     4.7 Choice of Law.

     This agreement shall be governed by the laws of the State of New Jersey.
