Exhibit 5.3


                                PLEDGE AGREEMENT

         This Pledge  Agreement (the  "Agreement"),  dated December 18, 1998, is
made by MLC HOLDINGS, INC., a Delaware corporation ("Pledgor") in favor of FIRST
UNION NATIONAL BANK (the  "Pledgee"),  as agent for itself and on behalf of each
of the banks now or hereafter party to the Credit Agreement (defined below). All
references in this  Agreement to "Pledgee"  shall mean First Union National Bank
as agent  for  itself  and the  other  Banks  under the  Credit  Agreement.  All
capitalized terms not defined in this Agreement shall have the meanings assigned
to them in the Credit Agreement.

                              Preliminary Statement

         Pledgor owns 100% of the capital stock of each of the companies  listed
on Schedule 1 hereto.

         Pledgor and Pledgee are parties to a Credit  Agreement  dated  December
18,  1998  (as  from  time to time  amended,  revised,  modified,  supplemented,
restated,  replaced, or otherwise substituted therefor, the "Credit Agreement"),
by and among Pledgor, MLC Group, Inc. ("MLC"), and MLC Federal, Inc. ("Federal")
as Borrowers, the banking institutions signatories thereto, and Pledgee as agent
for  itself  and  the  other  banking  institutions  (Pledgee  and  the  banking
institutions collectively the "Banks" and individually a "Bank").

         It is a condition to the  execution of the Credit  Agreement  that this
Agreement be executed and delivered by Pledgor in favor of Pledgee.

         Pledgor will  benefit from the Loans to itself and the other  Borrowers
under  the  terms  and  conditions  of the  Credit  Agreement,  and the Board of
Directors of Pledgor has  determined  that the execution and delivery by Pledgor
of this  Agreement is necessary  and  convenient  to the conduct,  promotion and
attainment of its business.

         NOW,  THEREFORE,  in  consideration  of the foregoing  premises and for
other good and valuable consideration,  the receipt and sufficiency of which are
hereby  acknowledged,  and intending to be legally bound hereby,  Pledgor hereby
makes the following  representations and warranties to Pledgee and covenants and
agrees with Pledgee as follows:

         1. Pledge of Stock. As collateral security for the punctual payment and
performance  of all  existing  and future  indebtedness  and other  liabilities,
absolute  or  contingent,  direct or  indirect,  primary  or  secondary,  of any
Borrower to each Bank and to all Banks, of any nature  whatsoever  arising under
the Credit Agreement and the Notes issued thereunder (the "Notes"), that certain
Security Agreement dated December 18, 1998 by and among Pledgor, MLC and Federal
as Debtors and Pledgee as Secured Party (the  "Security  Agreement"),  and under
any other Loan Document,  and all the  obligations of Pledgor  hereunder (all of
such  indebtedness,  liabilities and  obligations  being  hereinafter  sometimes
referred to  collectively  as the  "Obligations"),  Pledgor  hereby  pledges and
collaterally  assigns to Pledgee and grants to Pledgee  and agrees that  Pledgee
shall  have a first  priority  security  interest  in and  pledge of 100% of the
issued and outstanding shares of capital stock of each domestic subsidiary,  and
65% of the issued and outstanding shares of voting capital stock and 100% of the
issued  and  outstanding  shares of  non-voting  capital  stock of each  foreign
subsidiary,  as set forth on Schedule 1 hereto  (such shares  together  with any

                                      -1-


shares  or  other  securities  or  property  referred  to in  Section  6,  being
hereinafter sometimes referred to collectively as the "Pledged Securities").

         2.  Representations and Warranties.  Pledgor represents and warrants to
and agrees with Pledgee as follows:

         (a) Pledgor has examined and is fully  familiar and satisfied  with the
Credit Agreement,  Notes, Security Agreement,  and all other Loan Documents, and
all the representations and warranties set forth therein,  whether in respect of
Pledgor or otherwise, are accurate in all respects on and as of the date hereof.

          (b) The Pledged Securities are duly and validly issued, fully paid and
non-assessable  and have been duly and validly  pledged  hereunder in accordance
with law, and Pledgor warrants and covenants to defend Pledgee's right, security
interest and special property interest in and to the Pledged  Securities against
the  claims and  demands of all  persons  whomsoever.  Pledgor is the  exclusive
legal, equitable and beneficial owner of, and has good title to, all the Pledged
Securities on Schedule 1 hereto, free and clear of all claims,  liens,  security
interests and other  encumbrances  (except for the security  interest created in
favor of  Pledgee),  and Pledgor has the  unqualified  legal right to pledge the
same hereunder.  The Pledged Securities  constitute 100% of the issued shares of
any class of capital  stock of each domestic  subsidiary,  and 65% of the issued
voting  shares  and  100%  of  the  issued  nonvoting  shares  of  each  foreign
subsidiary,  respectively,  outstanding  on the date  hereof.  Each  certificate
evidencing any of the Pledged  Securities pledged hereunder by Pledgor is issued
in the name of Pledgor  and has  attached a stock  power duly signed in blank by
Pledgor with all  appropriate  signature  guarantees and bears no restrictive or
cautionary  legend.  The security  interest  created hereby or intended so to be
represents a valid lien on and security interest in the Pledged Securities,  and
such security interest is superior and prior in right to the rights of all third
persons. The parties acknowledge that, at such time as Pledgee is deemed to have
received possession of the Pledged Securities for purposes of this Agreement, no
filings or recordings  (including  without  limitation filings under the Uniform
Commercial  Code) will be necessary to be made to perfect,  protect and preserve
the  security  interest  of Pledgee in the  Pledged  Securities  created by this
Agreement or intended so to be.

         (c) Pledgor,  for itself and its  successors  and assigns,  does hereby
irrevocably  waive and release all preemptive,  first-refusal  and other similar
rights to purchase any or all of the Pledged Securities upon any sale thereof by
Pledgee   hereunder,   whether   such  right  to  purchase   arises   under  the
organizational  documents of any subsidiary,  by agreement, by operation of law,
or otherwise.

         (d) All the foregoing representations,  warranties and agreements shall
survive the execution and delivery of this Agreement,  the Credit Agreement, the
Security Agreement, the Notes, and all other Loan Documents.

         3.  Reregistration of Shares. At any time and from time to time Pledgee
may cause all or any of the Pledged  Securities to be transferred  into its name
or into the name of its nominee or nominees.

     4.  Reservation  of Voting  Rights.  Upon the  occurrence  and  during  the
continuance of an Event of Default, Pledgee shall be entitled (b)ut shall not be
obligated)  to  exercise  any and all voting  power with  respect to the Pledged
Securities. At all other times Pledgor shall be entitled to exercise in a manner
not  inconsistent  with the  provisions of this  Agreement all voting power with
respect to the Pledged Securities.

                                       2





     5. Preservation and Protection of Collateral.

         (a) Pledgee  shall be under no duty or  liability  with  respect to the
collection,  protection or preservation of the Pledged Securities, or otherwise,
other  than the  obligation  to deal with the  Pledged  Securities  while in its
possession  in the same  manner as Pledgee  deals  with  similar  securities  or
property for its own account.

         (b)  Pledgor  agrees  to pay when due all  taxes,  charges,  Liens  and
assessments  against  its  respective  Pledged  Securities  in  which  it has an
interest,  unless  being  contested  in good  faith by  appropriate  proceedings
diligently  conducted and against which adequate  reserves have been established
in  accordance  with GAAP and  evidenced  to the  satisfaction  of  Pledgee  and
provided  further  that all  enforcement  proceedings  in the  nature of levy or
foreclosure  are  effectively  stayed.  Upon the failure of Pledgor to so pay or
contest such taxes,  charges,  Liens or assessments,  Pledgee at its sole option
may pay or contest any of them  (Pledgee  having the sole right to determine the
legality or validity and the amount necessary to discharge such taxes,  charges,
Liens or assessments.)

         6.  Additional  Collateral  Security.   If,  upon  the  dissolution  or
liquidation (in whole or in part) of any subsidiary listed on Schedule 1 hereto,
any sum shall be paid upon or with  respect  to any of the  Pledged  Securities,
such sum shall be paid  over to  Pledgee  to be held by  Pledgee  as  additional
collateral  security for the  Obligations.  In case any stock  dividend shall be
declared on any of the Pledged  Securities,  or any shares of stock or fractions
thereof shall be issued pursuant to any stock split involving any of the Pledged
Securities,  or any  distribution of capital shall be made on any of the Pledged
Securities,  or any property  shall be  distributed  upon or with respect to the
Pledged Securities  pursuant to any  recapitalization or reclassification of the
capital  of any  subsidiary  listed on  Schedule  1  hereto,  or  pursuant  to a
reorganization  thereof,  the shares or other property so  distributed  shall be
delivered to Pledgee as additional collateral security for the Obligations.

         7. Remedies in General.  Upon the occurrence and during the continuance
of an Event of Default,  Pledgee  shall have,  without  obligation  to resort to
other security or to recourse  against any guarantor or other party  secondarily
liable, the right at any time and from time to time to sell, resell,  assign and
deliver, in Pledgee's discretion,  all or any of the Pledged Securities,  in one
or more parcels at the same or different times, and all right, title,  interest,
claim and demand therein and right of redemption  thereof,  at public or private
sale,  for cash,  upon credit or for immediate or future  delivery,  and at such
price or prices and on such  terms as  Pledgee  may  determine,  Pledgor  hereby
agreeing  that upon any such  sale any and all  equity  and right of  redemption
shall be  automatically  waived and released  without any further  action on the
part of Pledgor,  and in connection  therewith  Pledgee may grant  options,  all
without any demand,  advertisement or notice,  all of which are hereby expressly
waived.  In the event of any such sale,  Pledgee shall,  at least 10 days before
the sale,  give Pledgor  notice of its  intention  to sell which notice  Pledgor
agrees is reasonable.  Upon each such sale,  Pledgee or Pledgor may purchase all
or any of the  Pledged  Securities  being  sold,  free of any equity or right of
redemption.  The  proceeds  of each such sale shall be applied to the payment of
all costs and expenses of every kind for sale or delivery,  including reasonable
compensation  to the agents and  attorneys of Pledgee,  and all other  expenses,
liabilities  and advances made or incurred by Pledgee in  connection  therewith,
and after  deducting such costs and expenses from the proceeds of sale,  Pledgee
shall  apply any  residue  to the  payment of the  Obligations  in such order as
Pledgee may deem fit. The balance,  if any,  remaining  after payment in full of
the  Obligations  shall be paid over to Pledgor.  Upon the occurrence and during
the  continuance  of an Event of  Default,  Pledgee  shall  also  have,  without
obligation to resort to other  security or to recourse  against any guarantor or
other party secondarily liable and in addition to the

                                      3




other  remedies  provided in this Section 7, the right at any time and from time
to time, but not the obligation, to exercise ownership of the Pledged Securities
and to take all actions as may be permitted under applicable law.

         8.  Certain  Securities  Law  Undertakings.  In the  event  Pledgee  is
permitted to sell any of the Pledged Securities  pursuant to Section 7, upon the
written  request  of  Pledgee  to  cause  any  registration,   qualification  or
compliance under any federal or state securities law or laws to be effected with
respect to any of the Pledged Securities,  Pledgor as soon as practicable and at
its expense will use its best efforts to cause such registration,  qualification
or compliance to be effected (and be kept  effective) as may be so requested and
as  would  permit  or  facilitate  the  sale and  distribution  of such  Pledged
Securities.  Pledgor  will use its best  efforts  to  cause  Pledgee  to be kept
reasonably  advised  in writing as to the  progress  of each such  registration,
qualification or compliance and as to the completion thereof and will furnish or
use its best  efforts to cause to be furnished  to Pledgee,  without  expense to
Pledgee,  such number of prospectuses or offering  circulars and other documents
incident  thereto as Pledgee may from time to time reasonably  request.  Pledgor
will  indemnify  and hold  harmless  Pledgee  from and  against  any  claims  or
liabilities  caused by any untrue  statement of a material fact or omission of a
material  fact  required to be stated in any  registration  statement,  offering
circular or prospectus used in connection with such  registration or compliance,
or necessary to make the statements  therein not  misleading,  except insofar as
such claims or liabilities are caused by any untrue  statement or omission based
on or in conformity with any written  statement  supplied by Pledgee.  If at any
time when Pledgee shall determine to exercise its rights to sell all or any part
of the Pledged Securities  pursuant to Section 7, such Pledged Securities or the
part thereof to be sold shall not,  for any reason,  be  effectively  registered
under the  Securities  Act of 1933 (the  "Securities  Act"),  Pledgee  is hereby
expressly  authorized  to sell such Pledged  Securities  or such part thereof by
private  sale in such  manner and under such  circumstances  as Pledgee may deem
necessary or  advisable in order that such sale may legally be effected  without
such registration. Without limiting the generality of the foregoing, in any such
event  Pledgee:  (a) may  proceed  to make such  private  sale  whether or not a
registration  statement for the purpose of registering the Pledged Securities or
such part  thereof  shall  have been filed  under the  Securities  Act;  (b) may
approach and  negotiate  with a restricted  number of  potential  purchasers  to
effect  such  sale;  and (c) may  restrict  such  sale to a  limited  number  of
purchasers  that meet certain  requirements  as to nature of business,  level of
sophistication  and  investment  intention  (including  without  limitation,  to
purchasers each of whom will represent and agree to the  satisfaction of Pledgee
that such purchaser is purchasing for its own account,  for investment,  and not
with a view to the  distribution  or sale of  such  Pledged  Securities  or part
thereof).  Pledgee  may require  Pledgor,  and  Pledgor  hereby  agrees upon the
written  request of Pledgee,  to cause:  (i) a legend or legends to be placed on
the  certificates  to be  delivered  to such  purchasers  to the effect that the
offering and sale of the Pledged  Securities  represented  thereby have not been
registered  under the  Securities  Act and  setting  forth or  referring  to any
required  restrictions on the transferability of such Pledged  Securities;  (ii)
the  issuance  of  stop  transfer  instructions  to the  transfer  agent  of any
subsidiary  with  respect  to the  Pledged  Securities  (or if  such  subsidiary
transfers  its own  securities,  a notation in the  appropriate  records of such
subsidiary);  and  (iii) to be  delivered  to the  purchasers  a signed  written
agreement of Pledgor and such subsidiary,  that such purchasers will be entitled
to the rights of Pledgee  under this  Section 8. In addition,  it is  understood
that any such  purchasers  may be required  as a  condition  of any such sale to
furnish a signed written agreement that the Pledged  Securities will not be sold
without registration or other compliance with the requirements of the Securities
Act.  In the event of any such sale,  Pledgor  hereby  consents  and agrees that
Pledgee shall not incur any  responsibility  or liability for selling all or any
part  of the  Pledged  Securities  at a price  which,  Pledgee  in its  absolute
discretion,  may deem reasonable under the  circumstances,  notwithstanding  the
possibility that a substantially higher price might be realized if the sale were
public and deferred until after registration as aforesaid.

                                       4


         9. Rights and Remedies Cumulative;  Indemnities. The rights, powers and
remedies provided herein in favor of Pledgee shall not be deemed exclusive,  but
shall be  cumulative,  and shall be in addition to all other rights and remedies
in favor of Pledgee existing at law or in equity,  including without  limitation
all the  rights,  powers and  remedies  available  to a secured  party under the
Uniform  Commercial Code as in effect in the Commonwealth of Pennsylvania or any
other  appropriate  jurisdiction.  Pledgor  shall  indemnify  and save  harmless
Pledgee from and against any and all  liabilities,  losses and damages  which it
may  incur in the  exercise  or  performance  of any of its  rights,  powers  or
remedies set forth herein;  provided,  however,  that Pledgor shall not have any
obligation  to indemnify  any such  indemnitee  against any  liability,  loss or
damage resulting from such indemnitee's own gross negligence or bad faith.

         10. Right to Execute  Endorsements.  Pledgee shall have the right,  for
and in the name,  place and stead of Pledgor and acting as its  attorney-in-fact
if necessary,  to execute  endorsements,  assignments  and other  instruments of
conveyance  or transfer  with  respect to all or any of the  Pledged  Securities
whenever any such execution is required or permitted hereunder.

         11.  No  Waiver;  Amendments.  No  delay  on the  part  of  Pledgee  in
exercising  any of its  options,  powers or  rights,  and no  partial  or single
exercise  thereof,  shall  constitute a waiver  thereof or of any other  option,
power or right.  None of the  terms  and  conditions  of this  Agreement  may be
amended,  modified or waived orally but only in a writing  signed by Pledgee and
Pledgor.

         12.  Termination  of  Agreement;  Return  of  Collateral.  Should  this
Agreement  become  temporarily  inoperative  for any reason  (including  without
limitation the payment of all the Obligations)  prior to the Credit  Termination
Date (as defined in the Credit  Agreement),  this Agreement  shall  nevertheless
continue in effect through the Credit Termination Date to secure the payment and
performance  of all future  Obligations  whenever and as often as they may arise
hereunder or under the Credit Agreement,  the Security Agreement,  Notes, or any
other Loan Document.  However,  upon the full payment and performance of all the
Obligations and the termination of the Credit Agreement,  the Security Agreement
and  Notes,  this  Agreement  shall  expire  and  Pledgor  (except to the extent
otherwise  contemplated  hereby)  shall be  entitled to the return of all of its
respective  Pledged  Securities  and  other  property  and cash  held in  pledge
hereunder which have not been used or applied to the payment of the Obligations.

         13.  Further  Assurances;  Immunities.  With  respect  to  the  Pledged
Securities and any security  interest of Pledgee therein,  Pledgor agrees to do,
file, record,  make, execute and deliver all such acts, deeds,  things,  notices
and  instruments  as may be  necessary or desirable in the opinion of Pledgee in
order to vest more fully in and assure to Pledgee the security  interests in the
Pledged  Securities  created hereby or intended so to be and the enforcement and
realization of all of the benefits of the rights, remedies and powers of Pledgee
hereunder relating to the Pledged Securities. Without limiting the generality of
the  foregoing,  if at any time  hereafter,  whether or not due to any change in
circumstances  (including without limitation any change in applicable law or any
decision hereafter made by a court construing any applicable law), it is, in the
opinion of counsel for  Pledgee,  necessary  or desirable to file or record this
Agreement  or any  financing  statement  or other  instrument  relating  hereto,
Pledgor  agrees to pay all fees,  costs and expenses of such recording or filing
and to execute and deliver any instruments which may be necessary or appropriate
to make such filing or recording effective.  Pledgor hereby irrevocably appoints
Pledgee its  attorney-in-fact to perform, in Pledgor's name or Pledgee's name or
otherwise, any and all acts, including without limitation the signing and filing
of financing statements and amendments thereto, which Pledgee may deem necessary
or appropriate to effect and continue the security  interests  created hereby or
intended so to be or otherwise  to

                                       5



preserve and protect the Pledged Securities and the security interest of Pledgee
therein, but nothing herein contained or otherwise shall require Pledgee to take
any such action.  The duty of Pledgee in respect of the Pledged Securities shall
be  strictly  confined  to  one  of  reasonable  care  in  the  custody  of  the
certificates  therefor so long as they are in the  custody of  Pledgee.  Without
limiting the  generality of the preceding  sentence,  Pledgee shall not be under
any duty to anyone to send any notices, perform any services, vote, exercise any
options or elections with respect to, pay any taxes or charges  associated with,
or  otherwise  take any action of any kind with  respect  to, any of the Pledged
Securities.

         14.  Transfers  of  Interest.  Pledgee may transfer its interest in the
Pledged  Securities,  or any part thereof, to any replacement or successor agent
under the Credit  Agreement,  who shall  thereupon  become  vested  with all the
rights, remedies, powers, security interests and liens herein granted to Pledgee
in respect of the Pledged  Securities or the transferred part thereof,  subject,
however, to the restrictions contained herein.

         15. Expenses.  Pledgor agrees that the Pledged  Securities  secure, and
further  agrees to pay on demand,  all  reasonable  expenses  (including but not
limited to attorneys' fees and costs for legal services,  costs of insurance and
payments of taxes or other  charges) of, or  incidental  to, the custody,  care,
sale or realization  on any of the Pledged  Securities or in any way relating to
the enforcement or protection of the rights of Pledgee hereunder.

         16. Notices. All notices, requests, demands,  directions,  declarations
and other  communications  provided  for herein  shall be in writing  (including
telegraphic  and facsimile  communication)  and shall be mailed by registered or
certified mail, return receipt requested,  or telecopied or delivered in hand to
the applicable  party at its address  indicated  below, or, as to each party, at
such other  address as shall  hereafter be designated by such party in a written
notice to the others  complying as to delivery  with the terms of this  Section.
Each such notice, request, demand, direction, declaration or other communication
shall,  if mailed,  be effective when deposited in the mails,  postage  prepaid,
addressed as aforesaid, and shall, if sent by telegram or facsimile (telecopier)
or delivered in hand or by overnight courier, be effective when received.

rights  and  obligations  of the  parties  hereunder  shall be  governed  by and
construed  and  enforced  in  accordance  with the laws of the  Commonwealth  of
Pennsylvania.  Pledgor hereby consents to the  jurisdiction of the courts of the
Commonwealth of  Pennsylvania  in any action or proceeding  which may be brought
against  Pledgor  under  or in  connection  with  this  Agreement  or any of the
transactions contemplated hereby or to enforce any undertaking contained herein,
and in the event any such  action or  proceeding  shall be brought  against  it,
Pledgor agrees not to raise any objection to such  jurisdiction or to the laying
of the venue thereof in Pennsylvania, and further agrees that service of process
in any such action or proceeding may be duly effected upon Pledgor by service in
accordance  with the  provisions  of the Uniform  Interstate  and  International
Procedure Act as in effect in Pennsylvania.

         18. Certain Waivers;  Integration.  Pledgor hereby waives notice of any
and all  defaults  on the part of MLC and  Federal  under the Credit  Agreement,
Security  Agreement,  Notes or other  Loan  Documents.  Pledgor  further  waives
presentment for payment, protest, dishonor and notice of dishonor and of protest
with respect to the Notes.  This  Agreement  states the entire  agreement of the
parties  concerning the subject matter hereof, and it is acknowledged that there
are no customs, usages, representations,  or assurances referring to the subject
matter hereof,  and no inducements  leading to the execution or delivery hereof,
other than those expressed herein.

         19.  Counterparts.  This  Agreement  may be  executed  in any number of
counterparts  and all  the  counterparts  taken  together  shall  be  deemed  to
constitute one and the same instrument.

         20.  Miscellaneous.  This Agreement shall bind and inure to the benefit
of Pledgor and Pledgee and their respective successors and assigns,  except that
Pledgor  shall not have the  right to  assign  any of its  rights  hereunder  or
interests  herein without the written consent of Pledgee.  No persons other than
Pledgor, Pledgee and the other Banks, and the assignees of Pledgee and the other
Banks are intended to be benefited hereby or shall have any rights hereunder, as
third-party beneficiaries or otherwise. Pledgor acknowledges that this Agreement
and the obligations of Pledgor hereunder and the security created or intended to
be created hereby have constituted,  and were intended by Pledgor to constitute,
a material inducement to Pledgee and the Banks to execute and deliver the Credit
Agreement (which will inure to the direct and immediate  benefit of Pledgor as a
Borrower under such Credit  Agreement),  knowing that Pledgee and the Banks will
rely upon this Agreement.  Pledgor intends this to be a sealed instrument and to
be legally bound hereby.  Any provision of this 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  affecting the
