Datatec in accordance with their respective  terms. This Agreement has been duly
executed and  delivered by Datatec and  constitutes  a legal,  valid and binding
obligation of Datatec,  enforceable in accordance with its terms,  except (i) as
such enforceability may be limited by or subject to any bankruptcy,  insolvency,
reorganization,  moratorium or other similar laws  affecting  creditors'  rights
generally, (ii) as such obligations are subject to general principles of equity,

laws or by public policy.

                  Section 3.5 REQUIRED FILINGS AND CONSENTS; NO CONFLICT. Except

Datatec  or the  Subsidiaries  or by which any of their  properties  are  bound,
except for conflicts,  breaches, defaults, events of default or impositions that
would not have a Datatec  Material Adverse Effect.  The execution,  delivery and
performance  of  the  Agreements  by  Datatec  and  the   consummation   of  the
transactions  contemplated hereby and thereby will not result in the loss of any
license,  franchise,  legal  privilege  or permit  possessed  by  Datatec or the
Subsidiaries  or give a right of  termination  to any party to any  agreement or
other  instrument to which Datatec or any of the  Subsidiaries  is a party or by
which  any of  its  properties  are  bound,  except  for  losses  or  rights  of

or contract to have been made or approved by Datatec or any Subsidiary  under or

and the consummation of the transactions contemplated hereby will not constitute
a material  breach of any instrument or agreement  governing any Datatec Rights,

any  Subsidiary  received  any notice  asserting  that any Datatec  Right or the

with the rights of any other party,  nor, to the best  knowledge of Datatec,  is
there any basis for any such assertion; and

                  (d) Neither  Datatec nor any Subsidiary  has received  notice,

                  REPRESENTATIONS AND WARRANTIES OF THE SELLERS

                  Each Seller individually hereby represents and warrants to the
Buyer, with respect to such Seller as follows:

                  Section  4.1  CAPITALIZATION.  Each  Seller owns the number of
shares of  Datatec  Common  Stock as set forth next to his name under the column
"Datatec  Shares  Held" on  SCHEDULE  1.1  hereto,  free and clear of all liens,
claims or encumbrances.  Each Seller has full right,  power,  legal capacity and
authority to transfer and deliver the Shares pursuant to this Agreement.

                  Section  4.2  AUTHORITY  RELATIVE  TO  AND  VALIDITY  OF  THIS
AGREEMENT.  This  Agreement  has been duly executed and delivered by each of the
Sellers and constitutes the legal, valid and binding obligations of such Seller,
enforceable in accordance with its terms,  except (i) as such enforceability may
be  limited  by  or  subject  to  any  bankruptcy,  insolvency,  reorganization,
moratorium or other similar laws affecting creditors' rights generally,  (ii) as
such obligations are subject to general principles of equity and (iii) as rights
to  indemnity  may be limited by federal or state  securities  laws or by public
policy. Neither the execution and delivery by the Sellers of this Agreement, nor
the  consummation  of the  transactions  contemplated  hereby,  will violate any
provision of law, any order of any court or other agency of  government,  or any
judgment,  award or decree or any  indenture,  agreement or other  instrument to
which each


                                      -13-

<PAGE>
Seller is a party, or by which he or any of his properties or assets is bound or
affected,  or result in a breach of or  constitute  (with due notice or lapse of
time or both) a default under any such indenture, agreement or other instrument,
or result in the creation or imposition of any lien,  charge or  encumbrance  of
any nature whatsoever upon any of the properties or assets of such Seller.

                  Section 4.3 BROKERS' OR FINDERS' FEES.  Except as set forth in
SCHEDULE  3.18  hereto,  all  negotiations  relative to this  Agreement  and the
transactions  contemplated  hereby have been carried out by the Sellers directly
with the Buyer,  without the  intervention of any person on behalf of the Seller
in such manner as to give rise to any claim by any person  against the Buyer for
a finder's fee, brokerage commission or similar payment.

                  Section  4.4  SELLERS'   ADDRESSES,   ACCESS  TO  INFORMATION,
EXPERIENCE, ETC.

                           (a) The address set forth on the  signature  pages of
this Agreement is each Seller's true and correct business, residence or domicile
address.  Each Seller has received and read and is familiar with this Agreement.
Each Seller has had an opportunity to ask questions of and receive  answers from
representatives  of the  Buyer  concerning  the  terms  and  conditions  of this
investment.  Each Seller and/or his financial advisor has substantial experience
in business and financial  affairs and is capable of  evaluating  the merits and
risks of his  investment  decision  to purchase  of the  Glasgal  Common  Shares
hereby.

                           (b)  Each  Seller  acknowledges  that  it has  had an
opportunity  to evaluate all  information  regarding  the Buyer as it has deemed
necessary or desirable in connection with the transactions  contemplated by this
Agreement,  has  independently  evaluated the transactions  contemplated by this
Agreement and has reached its own decision to enter into this Agreement.

                  Section 4.5 PURCHASE  ENTIRELY  FOR OWN  ACCOUNT.  The Glasgal
Common Shares to be received by each Seller pursuant to the terms hereof will be
acquired for  investment  for each  Seller's  own  account,  not as a nominee or
agent, and not with a view to the resale or distribution of any part thereof.

                  Section 4.6  RESTRICTED  SECURITIES.  Each Seller  understands
that the Glasgal Common Shares it is purchasing are characterized as "restricted
securities"  under  the  federal  securities  laws  inasmuch  as they are  being
acquired  from the Buyer in a transaction  not  involving a public  offering and
that under such laws and applicable  regulations  such  securities may be resold
without   registration   under  the  Securities  Act  only  in  certain  limited
circumstances.  In this regard,  each Seller represents that it is familiar with
Rule 144 promulgated under


                                      -14-

<PAGE>
the Securities Act ("Rule 144"),  as presently in effect,  and  understands  the
resale limitations imposed thereby and by the Securities Act.

                  Section 4.7 LEGENDS.  It is understood  that the  certificates
evidencing the Glasgal Common Shares may bear a legend substantially as follows:

                  "THE SECURITIES  REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED  UNDER THE  SECURITIES ACT OF 1933, AS AMENDED (THE
                  "ACT"),  OR UNDER THE SECURITIES LAWS OF ANY STATE AND MAY NOT
                  BE TRANSFERRED  UNTIL (I) A REGISTRATION  STATEMENT  UNDER THE
                  ACT SHALL HAVE BECOME  EFFECTIVE  WITH REGARD THERETO AND THEY
                  SHALL HAVE BEEN  REGISTERED  OR  QUALIFIED  FOR SALE UNDER THE

                  COUNSEL TO THE  CORPORATION,  REGISTRATION  AND  QUALIFICATION
                  UNDER THE ACT AND THE SECURITIES LAWS OF THE APPROPRIATE STATE
                  IS NOT REQUIRED IN CONNECTION WITH SUCH PROPOSED TRANSFER."

                  The  legend  referred  to above  shall be removed by the Buyer
from any certificate at such time as the holder of the shares represented by the
certificate delivers an opinion of counsel reasonably  satisfactory to the Buyer
to the effect that such legend is not required in order to establish  compliance
with any provisions of the Securities Act, or at such time as the holder of such
shares  satisfies  the  requirements  of Rule 144(k) under the  Securities  Act,
provided  that the Buyer has received  from the holder a written  representation
that  (i) such  holder  is not an  affiliate  of the  Buyer  and has not been an
affiliate of the Buyer during the preceding  three (3) months,  (ii) such holder
has beneficially owned the shares represented by the certificate for a period of
at least three (3) years or such shorter period as required by Rule 144(k),  and

instrument to which the Buyer,  Signatel,  CASI or HH may be a party or by which
the  Buyer,  Signatel,  CASI or HH (or any of their  respective  properties)  is
bound,  or (c) any  material  law,  administrative  regulation  or rule or court
order,  judgment or decree  applicable to the Buyer;  nor will the execution and

hereby  constitute  a material  breach of, or any event of  default  under,  any
material  contract  or  agreement  to which the Buyer,  Signatel,  CASI or HH is
bound, or by which the Buyer,  Signatel,  CASI or HH (or any of their respective

Sellers shares for its own account for  investment  purposes only and not with a

managing  underwriter  of such  offering,  and perform its  obligations  under a
lock-up agreement similar in form and substance to lock-up  agreements  executed

                  (c)      provide a guaranty to CoreStates in a form reasonably
                           satisfactory to CoreStates;

                  (d)      commit  additional  financial  support  to Datatec to
                           enable  Datatec to comply with  CoreStates  financial
                           covenants;

                  (e)      not purchase,  pool or merge with another company nor

                  (f)      provide  CoreStates  with all of the  information  it
                           requests  on a timely  basis  and  allow  Datatec  to
                           comply as long as the  CoreStates  loan is in effect,
                           and provide information regarding the Buyer's ability
                           to raise additional funds.

                  Section 6.9 CERTAIN  OPERATIONS.  Following  the Closing,  the

such sale by Plan C, L.L.C. to the Buyer for immediate  payment to CoreStates as
required by the Credit  Facilities,  the Buyer shall issue a promissory  note to
Plan C, L.L.C. (the "Plan C Note"). In addition,  following the payment by Carey
to CoreStates of an amount up to $500,000 (the "Carey Payment"), the Buyer shall
issue a note to Carey  (the  "Carey  Note").  The Plan C Note and the Carey Note
shall be in  amounts  equal to the  amount  of the Plan C  Payment  or the Carey
Payment, respectively,  shall be due no later than 24 months from the respective
payment date, and shall accrue interest at a rate of 12.5% per annum. The Plan C
Note shall be subject to  certain  prohibitions  on the  ability of the Buyer or
affiliates  of the  Buyer  to  make  payments  to Plan C,  L.L.C.  prior  to the
repayment  in full of amounts  owed by the Buyer or  affiliates  of the Buyer to
CoreStates,  however,  to the extent that any amounts are owed to Plan C, L.L.C.
under the Plan C Note, once such prohibitions are no longer in effect, the Buyer
shall pay all amounts due thereunder.  In addition, the Buyer shall issue 15,000
additional shares of Glasgal Common Stock to Plan C, L.L.C. on the Closing Date.

                  Section 6.11 ADDITIONAL  COVENANTS OF DATATEC, THE SELLERS AND
THE BUYER. Each of Datatec, the Sellers and the Buyer covenant and agree:

                  (a)  BEST  EFFORTS.  To  proceed  diligently  and use its best

parties  of (i)  the  occurrence,  or  failure  to  occur,  of any  event  whose
occurrence or failure to occur,  would be likely to cause any  representation or

respect  at any time  from  the date  hereof  to the  Closing  Date and (ii) any
material failure on its part, or on the part of any of its officers,  directors,

                                      -23-

<PAGE>
notice shall not limit or otherwise affect the remedies  available  hereunder to
the party receiving such notice.

                  (d)  ACCESS.  To cause its  affiliates,  officers,  directors,
employees,  auditors and agents to afford the officers,  employees and agents of
the  other  party  hereto  complete  access  at all  reasonable  times  and upon

such press  releases  or make any such  public  statement  prior to such  mutual
agreement, except as may be required by law.


                                   ARTICLE VII

                      REGISTRATION OF GLASGAL COMMON SHARES

                  Section 7.1 FILING OF REGISTRATION  STATEMENTS.  (a) The Buyer
will file a registration  statement  ("Registration  Statement") with respect to
the resale by the Sellers (i) of such number of shares having an aggregate share
value  (as  defined  below) of  $2,000,000,  as soon as  reasonably  practicable
following the publication by the Buyer of results of its operations which


                                      -24-

<PAGE>
contain 30 days of results of combined  operations  of the Buyer and Datatec and
(ii) of 15,000  shares in excess of such  number of shares  having an  aggregate
Share Value of  $1,000,000,  as soon as  reasonably  practicable  following  the
completion by the Buyer of the audit of its financial  statements for the fiscal
year ending  April 30,  1997.  The  individual  Share Value shall be the average
closing  price of Glasgal  Common  Stock for the ten trading  days ending on the
third trading day prior to the filing of any such Registration  Statement.  Each
of the Registration  Statements described above will register the Glasgal Common
Shares pro rata as among the Sellers.

                  (b) If the Buyer at any time or from  time to time  subsequent
to the  effective  date  of the  Registration  Statement  described  in  Section
7.1(a)(ii)  proposes to register any Glasgal  Common Stock under the  Securities
Act for  its own  account  (other  than  pursuant  to a  registration  statement
(including  pre-effective  amendments  thereto) (i) on Form S-8 or any successor
form to such form,  (ii) on Form S-4 or any successor  form to such form,  (iii)
filed in  connection  with an exchange  offer or an  offering of Glasgal  Common
Stock or of securities  convertible  or  exchangeable  into Glasgal Common Stock
made solely to its existing shareholders in connection with a rights offering or
solely to  employees  of the Buyer,  or a  post-effective  amendment to any then
effective  registration  statement),  it will give written notice to each of the
Sellers of its  intention  at least twenty (20) days in advance of the filing of
any Registration Statement with respect thereto. Notwithstanding anything to the
contrary herein,  any notice otherwise  required by this Section shall not apply
if any agreement to which the Buyer is now, or to which the Buyer later becomes,
a party  prohibits  the  inclusion  of the Glasgal  Common  Stock from any given
Registration  Statement and any similar  provision to which the Buyer is subject
has not been waived with respect to any other party. Upon the written request of
any of the Sellers given within  fifteen (15) days after receipt of such notice,
the Buyer, subject to Section 7.1(c) below, will cause the Glasgal Common Shares
requested by the Sellers to be registered, to be so registered.

                  (c) (i) In the case of an  underwritten  offering by the Buyer
of Glasgal Common Stock, the Buyer shall,  with respect to Glasgal Common Shares
that a Seller then desires to sell,  enter into an  underwriting  agreement with
the same  underwriters  engaged by the Buyer with  respect to  securities  being
offered  by the  Buyer  and  cause  such  underwriters  to  include  in any such
underwriting  all of the Glasgal  Common  Shares  that a Seller then  desires to
sell; PROVIDED,  HOWEVER,  that such underwriting  agreement is in substantially
the same  form as the  underwriting  agreement  that the  Buyer  enters  into in
connection with the primary offering it is making.


                                      -25-

<PAGE>
                           (ii) If the managing  underwriter  with respect to an
offering  pursuant to this  Section 7.1  requests in writing  that the number of
Glasgal Common Shares of a Seller that are entitled to be registered pursuant to
this Section 7.1 be reduced because in the judgment of the managing  underwriter
the offering would be materially and adversely affected, then the Glasgal Common
Shares of the Sellers  that they wish to register  pursuant to this  Section 7.1
shall be reduced by such amount as the  managing  underwriter  may  determine in
writing so as to not  materially  and  adversely  affect the proposed  offering,
which  reduced  number of Glasgal  Common Shares shall be included on a pro rata
basis among the Sellers who are participating in such offering.

                  Section  7.2  REGISTRATION   PROCEDURES.   Each   Registration
Statement filed pursuant to this Article VII shall be pursuant to the procedures
set forth below:

                  (a) The Buyer shall, in accordance with the Securities Act and
the  rules  and  regulations  of the  SEC,  prepare  and  file  with  the  SEC a
Registration Statement in the form of an appropriate registration statement with
respect to the Glasgal Common Shares covered by such Registration  Statement and
use its best efforts to cause such Registration Statement to become effective as
soon as  possible  after  each  Registration  Statement  is  filed,  and  remain
continuously  effective,  until the  earlier  of (i) all of the  Glasgal  Common
Shares covered by such  Registration  Statement has been sold in accordance with
the intended  methods of  disposition of the seller or sellers set forth in such
Registration  Statement and (ii) 270 days after such Registration  Statement has
been  declared  effective  PROVIDED,  that if for any portion of such period the
Registration  Statement is not effective,  then such requirement for maintaining
the effectiveness of the Registration  Statement shall be extended by the length
of such interruption(s),  and the Buyer shall prepare and file with the SEC such
amendments to each such Registration Statement and supplements to the prospectus
contained therein as may be necessary to keep each such  Registration  Statement
effective  and each such  Registration  Statement  and  prospectus  accurate and
complete during such period;

                  (b) The Buyer shall notify the Sellers  participating  in such
registration,  promptly after it shall receive notice  thereof,  of the date and
time when such Registration Statement and each post-effective  amendment thereto
has become  effective or a supplement to any  prospectus  forming a part of such
Registration Statement has been filed;

                  (c) The Buyer  shall  furnish to the Sellers  such  reasonable
number of copies of the  Registration  Statement and  prospectus  and such other
documents as Sellers may  reasonably  request in order to facilitate  the public
offering of the Glasgal Common Shares;


                                      -26-

<PAGE>
                  (d) The  Buyer  shall  use its best  efforts  to  register  or
qualify the Glasgal Common Shares covered by such  Registration  Statement under
such state securities or blue sky laws of such  jurisdictions as the Sellers may
reasonably request, PROVIDED,  HOWEVER, that the Buyer shall not be obligated to
file any  general  consent  to  service  of  process  or to qualify as a foreign
corporation  in any  jurisdiction  in which it is not so qualified or to subject
itself to taxation in connection with any such  registration or qualification of
such securities;

                  (e) The Buyer shall notify the Sellers  participating  in such
registration   promptly  of  any  request  by  the  SEC  for  the   amending  or
supplementing  of such  Registration  Statement or prospectus or for  additional
information;

                  (f) The Buyer shall  prepare  and file with the SEC,  promptly
upon  the  request  of  any  Seller  participating  in  such  registration,  the
Registration  Statement and any amendments or  supplements to such  Registration
Statement or  prospectus  which,  in the  reasonable  opinion of counsel for the
Sellers  is  required  under the  Securities  Act or the  rules and  regulations
thereunder in connection  with the  distribution of the Glasgal Common Shares by
the Sellers or to otherwise  comply with the  requirements of the Securities Act
and such rules and regulations;

                  (g) The Buyer shall prepare and promptly file with the SEC and
promptly  notify the Sellers of the filing of such  amendments or supplements to
such  Registration  Statement or  prospectus  as may be necessary to correct any
statements  or  omissions  if, at the time  when a  prospectus  relating  to the
Glasgal  Common  Shares  securities  is  required  to  be  delivered  under  the
Securities  Act,  any  event  has  occurred  as the  result  of  which  any such
prospectus  or any  other  prospectus  then in  effect  may  include  an  untrue
statement of a material  fact or omit to state any material  fact required to be
stated therein or necessary to make the statements  therein not misleading.  The
Buyer  shall make  available  to the Sellers  and to the  underwriters  any such
supplement or amendment. The Sellers agree that, upon receipt of any notice from
the  Buyer  of the  occurrence  of any  event  of the  kind  described  in  this
subsection  (g), the Sellers will  forthwith  discontinue  the offer and sale of
Glasgal  Common  Shares  pursuant to the  Registration  Statement  covering such
Glasgal  Common  Shares  until  receipt by the Sellers and  underwriters  of the
copies of such  supplemented  or amended  prospectus  and, if so directed by the
Buyer,  the Sellers will deliver to the Buyer all copies,  other than  permanent
file  copies then in the  Sellers'  possession,  of the most  recent  prospectus
covering such Glasgal  Common  Shares at the time of receipt of such notice.  In
the event the Buyer shall give such  notice,  the Buyer shall  extend the period
during  which such  Registration  Statement  shall be  maintained  effective  as
provided in Section 7.2(a) hereof by the number of days during the period


                                      -27-

<PAGE>
from and  including  the date of the giving of such  notice to the date when the
Buyer  shall  make  available  to  the  Sellers  such  supplemented  or  amended
prospectus;

                  (h) The Buyer shall advise the Sellers  participating  in such
registration,  promptly  after it  shall  receive  notice  or  obtain  knowledge
thereof,  of  the  issuance  of  any  stop  order  by  the  SEC  suspending  the
effectiveness of such Registration Statement or the initiation or threatening of
any proceeding for that purpose and promptly use its best efforts to prevent the
issuance of any stop order or to obtain its withdrawal if such stop order should
be issued;

                  (i) The Buyer shall  otherwise  use its best efforts to comply
with  all  applicable  rules  and  regulations  of the SEC,  and make  generally
available to the Buyer's  security holders  earnings  statements  satisfying the
provisions of Section 11(a) of the Securities Act, no later than forty-five (45)
days after the end of any twelve (12) month period (or ninety (90) days, if such
a period is a fiscal year) beginning with the first month of the Company's first
fiscal quarter commencing after the effective date of a Registration Statement;

                  (j) The Buyer shall not file any  amendment or supplement to a
Registration  Statement  or  prospectus  to which a majority  in interest of the
Sellers participating in such registration has objected on the grounds that such
amendment  or  supplement  does not  comply in all  material  respects  with the
requirements  of the  Securities  Act or the rules and  regulations  thereunder,
after having been  furnished  with a copy thereof at least three  business  days
prior to the filing  thereof  unless the Buyer shall have obtained an opinion of
counsel that such amendment is required under the Securities Act or the rules or
regulations  adopted  thereunder in connection with the  distribution of Glasgal
Common Shares by the Sellers.

                  (k) The Buyer may, at its option,  register  additional shares
of Glasgal Common Stock in a Registration Statement for sale by other holders of
its Common Stock or include the Glasgal Common Shares in a registration in which

                                      -30-

<PAGE>
Grundman Frome & Rosenzweig LLP,  counsel to the Buyer,  dated as of the Closing
Date, in a form reasonably satisfactory to Datatec,  substantially to the effect
that: (i) the Buyer is a corporation  duly  organized,  validly  existing and in
good standing under the laws of its state of  incorporation;  (ii) the Buyer has
the  corporate  power  to enter  into  the  Agreements,  and to  consummate  the
transactions  contemplated hereby and thereby;  (iii) the execution and delivery
of the Agreements,  and the consummation of the transactions contemplated hereby
and thereby have been duly authorized by all requisite  corporate  action on the
part of the Buyer;  (iv) this  Agreement has been duly executed and delivered by
the Buyer and (assuming  that it is a valid and binding  obligation of the other
parties  thereto) is a valid and  binding  obligation  of the Buyer  enforceable
against the Buyer in accordance with its terms, except (a) as enforceability may
be  limited  by  any  bankruptcy,   insolvency  and  other  laws  affecting  the
enforcement  of  creditors'  rights  generally,  and as such  enforceability  is
subject  to  general   principles   of  equity   (regardless   of  whether  such
enforceability is considered in a proceeding in equity or at law), provided that
the opinion in (iv) shall not be interpreted as constituting an opinion that any
of the  provisions of the  Agreement do not  contravene a provision of law, have
the legal effect that they purport to have or are specifically enforceable,  (v)
the Glasgal Common Shares are duly  authorized,  validly issued,  fully-paid and
nonassessable;  and (vi) the execution, delivery or performance of the Agreement
by the Buyer and the  consummation by the Buyer of the transactions  herein,  to
the best of such counsel's knowledge, do not conflict with or result in a breach
of, or default under, the Buyer's  certificate of incorporation or bylaws or any
material   indenture,   mortgage,   deed  of  trust,   voting  trust  agreement,
stockholders  agreement,  note  agreement or other  material  agreement or other
material instrument to which the Buyer is a party or by which the Buyer is bound
or to which any of the property of the Buyer is subject.  Such opinion  shall be
limited  to the laws of the State of New York and  United  States  federal  law.
Insofar  as the  opinion  expressed  in (iv) above  relates to matters  that are
governed by the laws of the State of New Jersey,  the Buyer's counsel may assume
that the laws of the State of New Jersey are  identical to the laws of the State
of New York.

                  Section 8.7 MATERIAL  CHANGES.  Since the date  hereof,  there
shall not have been any material  adverse  change in the  business,  operations,

                                 INDEMNIFICATION

                  Section 10.1 INDEMNIFICATION BY CAREY AND KOCH. Subject to the
limits set forth in this Article X, Carey and Koch agree, pro rata in proportion
to the number of their  respective  Datatec  Shares being sold  pursuant to this
Agreement, to indemnify, defend and hold the Buyer and each of its directors and
officers harmless from and against any and all loss,  liability,  damage,  costs
and expenses (including interest,  penalties and attorneys' fees) (collectively,
"Losses") that the Buyer or any of its affiliates may incur or become subject to
arising out of or due to any (i) inaccuracy of any  representation or the breach
of any  warranty  or  covenant  of Carey,  Koch,  or Datatec  contained  in this
Agreement (it being  understood that the indemnity  obligation set forth in this
Section 10.1(i) shall not apply to any claim made by a former, current or future
stockholder  of the Buyer based on an  inaccuracy of any  representation  or the
breach of any warranty or covenant of Carey,  Koch or Datatec  contained in this
Agreement)  or (ii)  Losses  relating  to the  Securities  Act,  the  Securities
Exchange  Act of 1934,  as amended  or  otherwise,  insofar  as such  Losses (or
actions or proceedings,  whether  commenced or threatened,  in respect  thereof)
arise  out of or are  based  upon any  untrue  statement  of any  material  fact
contained in a Registration Statement or any amendment or supplement thereto and
which was included in a  Registration  Statement or any  amendment or supplement
thereto in reliance upon and in conformity with written information furnished to
the Buyer by Carey and the Sellers who are members of Carey's  immediate  family
or are  trusts  for the  benefit  of Carey or his  immediate  family or by Koch,
specifically  stating that it is for use in the preparation  thereof,  provided,
however,   that  Carey  shall  not  be  liable  for  any  misstatement  relating
specifically  to Koch and the Datatec Shares owned by Koch and Koch shall not be
liable  for any  misstatement  relating  specifically  to Carey and the  Datatec
Shares  owned by Carey.  Subject to  Section  10.3  hereof,  Carey and Koch will
reimburse the Buyer and each controlling person pro rata, as provided above, for
any legal or any other expenses


                                      -34-

<PAGE>
reasonably  incurred by them in connection with  investigating  or defending any
such loss, claim, liability, action or proceeding.

                  Section 10.2  INDEMNIFICATION  BY THE SELLERS.  Subject to the
limits  set forth in this  Article  X, each of the  Sellers,  solely as to their
individual  representations  and warranties and covenants,  agrees to indemnify,
defend and hold the Buyer and each of its directors  and officers  harmless from
and  against  any and all Losses,  that the Buyer or any of its  affiliates  may
incur or become  subject to arising out of or due to any (i)  inaccuracy  of any
representation  or the  breach  of  any  warranty  or  covenant  of the  Sellers
contained in this Agreement or (ii) Losses  relating to the Securities  Act, the
Exchange Act or  otherwise,  insofar as such Losses (or actions or  proceedings,
whether  commenced or threatened,  in respect thereof) arise out of or are based
upon any untrue  statement of any  material  fact  contained  in a  Registration
Statement  or any  amendment or  supplement  thereto and which was included in a
Registration  Statement or any amendment or supplement  thereto in reliance upon
and in conformity with written information furnished to the Buyer by such Seller
specifically  stating that it is for use in the preparation  thereof.  Each such
Seller will reimburse the Buyer and each controlling person for any legal or any
other expenses  reasonably  incurred by them in connection with investigating or
defending any such loss, claim, liability, action or proceeding.

                  Section 10.3 NOTICE OF CLAIM;  DEFENSE OF ACTION. In the event
that any  legal  proceedings  should be  instituted  or that any claim or demand
should be  asserted  by any third  party in respect of which the  obligation  to
indemnify may arise under the  provisions of Section 10.1,  the Buyer shall give
to Carey and Koch prompt written notice  thereof,  and Carey and Koch shall have
the right,  at their option and expense,  to be  represented by counsel of their
choice in connection  with the defense of any such claim or proceeding,  but not
to control the defense or settlement  thereof,  except as hereinafter  provided.
Carey and Koch may assume control of the defense or settlement of any such claim
or  proceeding  which  may  result in  liability  to Carey and Koch in excess of
$150,000  unless in the reasonable  judgment of the Buyer the assumption of such
control by Carey and Koch creates a significant risk of a significant continuing
adverse effect on the Buyer's business  operations,  in which case neither Carey
nor Koch shall be entitled to assume the control of the defense or settlement of
such claim.  If Carey and Koch are entitled to assume  control of the defense or
settlement  of any such claim or proceeding  pursuant to the preceding  sentence
and  either of them has  indicated  to the Buyer its  willingness  to do so in a
reasonably  timely  manner,  but the Buyer does not permit them to do so for the
reasons set forth in the preceding sentence or for any reason, neither Carey nor
Koch shall have any obligation to indemnify the Buyer with respect to such claim
or proceeding. In any event, Carey and Koch, on one hand, and the


                                      -35-

<PAGE>
Buyer on the other hand,  agree to cooperate with each other in connection  with
the defense of any such legal  proceeding,  claim,  or demand.  In addition,  if
Carey and Koch  assume the  defense of any such claim and the result is that the
Buyer is not  responsible  for damages,  the Buyer will reimburse Carey and Koch
for all reasonable expenses in connection with such defense.

         Section 10.4  INDEMNIFICATION  BY THE BUYER.  Subject to the limits set
forth in this  Article  X, the Buyer  agrees to  indemnify,  defend and hold the
Sellers  harmless  from and  against  any and all Losses that the Sellers or its
affiliates  may  incur or become  subject  to  arising  out of or due to (i) any
inaccuracy  of any  representation  or the breach of any warranty or covenant of
the Buyer  contained in this Agreement or (ii) the Securities  Act, the Exchange
Act or  otherwise,  insofar as such Losses (or actions or  proceedings,  whether
commenced or threatened,  in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in a
Registration  Statement or any amendment or supplement  thereto, or any omission
or alleged  omission  to state  therein a material  fact  required  to be stated
therein or necessary to make the  statements  therein not  misleading,  PROVIDED
that the Buyer  shall not be liable in any such case to the extent that any such
Losses (or action or  proceeding  in respect  thereof)  arise out of or is based
upon an untrue  statement  or alleged  untrue  statement  or omission or alleged
omission made in a Registration Statement or amendment or supplement thereto, in
reliance upon and in conformity with written information  furnished to the Buyer
through an instrument duly executed by the Sellers  specifically stating that it
is for use in the preparation  thereof. The Buyer will reimburse the Sellers for
any  legal or other  expenses  reasonably  incurred  by him in  connection  with
investigating  or  defending  any  such  loss,  claim,   liability,   action  or
proceeding.

                  Section 10.5 SURVIVAL.  The  representations and warranties of
Datatec, Carey, the Sellers and the Buyer set forth in Articles III, IV and V of
this  Agreement  shall survive the Closing until the earlier to occur of (i) the
first anniversary of the Closing Date and (ii) the completion and publication of
a 12 month audit of the combined results of operations of the Buyer and Datatec.
The covenants and agreements of the Sellers,  the Buyer, Datatec and Carey shall
not survive the Closing,  except for the covenants and  agreements  set forth in
Sections  6.3,  6.4,  6.5,  6.6 6.7,  6.9 and 6.10 and under  Articles VII and X
hereof.

                  Section  10.6  LIMITATIONS.  Notwithstanding  anything in this
Article X to the contrary,  in no event shall Carey, Koch or any other Seller be
liable for  indemnification  under this  Article X or  otherwise in an amount in
excess of $2,400,000  pro rata in  proportion to the number of their  respective
Datatec Shares being sold pursuant to this Agreement. In addition,


                                      -36-

<PAGE>
except as may otherwise be provided in this Agreement, no party shall assert any
claim  against  any other party or parties for  indemnification  hereunder  with
respect  to any  inaccuracy  or  breach  of  such  warranties,  representations,
covenants  or  agreements  unless and until the amount of all such claims  shall
exceed $25,000, and then only for the excess above $25,000,  PROVIDED,  HOWEVER,
that any  claim  against  Carey  relating  to a breach  of a  representation  or
warranty  contained  in Article IV or  Sections  3.2,  3.3,  or 3.8 shall not be
limited by this  provision.  With  respect to  possible  future  obligations  of
Datatec  which are set forth in (i) Item 1 of Schedule 3.6 hereto and (ii) Items
1, 2, and 3 of Schedule 3.8 hereto,  no party shall assert any claim against any
other party for  indemnification  hereunder  with  respect to any  liability  in
excess of the amounts  disclosed in such Item unless and until the liability for
any such  individual  Item exceeds the amount  disclosed in the relevant Item by
more than $150,000, and then only for the amount in excess of $150,000.

                  Section 10.7 REDUCTION FOR  INSURANCE.  The gross amount which
an indemnifying  party is liable to, for, or on behalf of the indemnified  party
pursuant  to  this  Article  X  (the  "Indemnifiable  Loss")  shall  be  reduced
(including,  without  limitation,   retroactively)  by  any  insurance  proceeds
actually  recovered  by or on behalf of such  indemnified  party  related to the
Indemnifiable  Loss. If an  indemnified  party shall have received or shall have
had paid on its behalf an indemnity payment in respect of an Indemnifiable  Loss
and shall  subsequently  receive  directly or indirectly  insurance  proceeds in
respect of such  Indemnifiable  Loss, then such  indemnified  party shall pay to
such indemnifying  party the net amount of such insurance  proceeds or, if less,
the amount of such indemnity payment.

                  Section 10.8 CONTRIBUTION. If the indemnification provided for
in this  Article X is  unavailable  to an  indemnified  party in  respect of any
Losses   relating  to  the  Securities  Act  or  the  Exchange  Act,  then  each
indemnifying  party, in lieu of indemnifying  such indemnified party as a result
of  such  Losses,  shall  contribute  to the  amount  paid  or  payable  by such
indemnified  party  as a  result  of  such  Losses  in  such  proportion  as  is
appropriate  to reflect the  relative  fault of the Buyer on the one hand and of
the Sellers,  Carey or Koch, as the case may be, on the other in connection with
any untrue statement or alleged untrue statement of a material fact contained in
a Registration  Statement or any amendment or supplement thereto or any omission
or alleged omission to state a material fact in a Registration  Statement or any
amendment or supplement thereto. The relative fault of the Buyer on the one hand
and of the  Sellers,  Carey or Koch,  as the case may be, on the other  shall be
determined by reference to, among other things,  the parties'  relative  intent,
knowledge, access to information and opportunity


                                      -37-

<PAGE>
to correct or prevent  such untrue  statement  or alleged  untrue  statement  or
omission or alleged omission.  No person guilty of fraudulent  misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation. In no event shall the obligation of any indemnifying party to
contribute  under this  Section  10.8 exceed the amount  that such  indemnifying
party  would  have  been  obligated  to pay by  way  of  indemnification  if the
indemnification  provided  for under  Sections  10.1,  Section  10.2 or 10.3 (as
limited by Section 10.6) had been available under the circumstances.

determined by PRO RATA allocation or by any other method of allocation that does
not take account of the equitable  considerations referred to in the immediately
preceding  paragraph.  The amount paid or payable by an  indemnified  party as a
result of the Losses referred to in the immediately preceding paragraph shall be
deemed  to  include,  subject  to the  limitations  set  forth in the  preceding
sentence,  any legal or other expenses  reasonable  incurred by such indemnified
party in connection with investigating or defending any such action or claim.
