AMENDED AND RESTATED
                      NON-QUALIFIED STOCK OPTION AGREEMENT
                      ------------------------------------

                  THIS AMENDED AND RESTATED NON-QUALIFIED STOCK OPTION
AGREEMENT, entered into as of the 19th day of May, 1997, between MICROFRAME,
INC., a corporation organized and existing under the laws of the State of New
Jersey (the "Corporation"), with its principal place of business at 21 Meridian
Road, Edison, New Jersey 08820 and Stephen B. Gray (the "Optionee").

                  The Corporation, in accordance with the consent of the
Compensation/Stock Option Committee (the "Committee") of the Board of Directors
granted the Optionee a nonqualified stock option on September 25, 1996 , subject
to the terms and conditions set forth in the non-qualified stock option
agreement dated as of September 25, 1996. After additional consideration by the
Committee, the Committee has determined and the Optionee has agreed that certain
of the terms and conditions of such stock option should be amended. For ease of
reference only, the non-qualified stock option agreement evidencing the grant of
a non-qualified option for 400,000 shares of the Common Stock of the Corporation
is hereby amended and restated in its entirety.

                              W I T N E S S E T H :
                               - - - - - - - - - -

         1. The Committee hereby grants as of September 25, 1996 to the Optionee
a nonqualified stock option to purchase an aggregate of 400,000 shares of common
stock, $.001 par value of the Corporation  ("Common Stock") at an exercise price
of $1.156  per  share,  being at least  equal to the fair  market  value of such
shares of Common Stock on the date thereof.  Shares of Common Stock to be issued
upon the  exercise of this option may, at the  election of the  Corporation,  be
either authorized and unissued shares or shares previously issued and reacquired
by the  Corporation.  This option  shall not be treated as an  "incentive  stock
option" under Section 422 of the Internal Revenue Code of 1986, as amended, (the
"Code") and shall not be  considered  an option  issued under the  Corporation's
1994 Stock Option Plan.

         2. This option shall be exercisable immediately as to 200,000 shares of
Common Stock subject  hereto,  and as to an additional  100,000 shares of Common
Stock on each of April 1, 1998 and April 1, 1999. In no event may this option be
exercised after the Expiration Date.

         3. This option shall  expire at the close of business on September  25,
2006 (the "Expiration Date").

         4. The right to purchase shares of Common Stock under this option shall
be  cumulative,  so that if the full  number of shares  purchasable  in a period
shall not be purchased, the balance may be purchased at any time or from time to
time thereafter, but not after the expiration of the option. Notwithstanding any
of the  foregoing,  in no event may a  fraction  of a share of  Common  Stock be
purchased under this option.

<PAGE>

         5. This option  shall be  exercised by the delivery by the Optionee (or
his  personal  representative,  as the case  may be) of  written  notice  to the
Corporation  at its principal  office,  presently  located at 21 Meridian  Road,
Edison,  New  Jersey  08820,  Attention:  Compensation/Stock  Option  Committee,
stating  that the  Optionee  is  exercising  this  non-qualified  stock  option,
specifying the number of shares being purchased and  accompanied by payment,  in
full of the aggregate purchase price therefor (a) in cash or by certified check,
(b) with previously  acquired shares of Common Stock which have been held by the
Optionee for at least six months having a Fair Market Value on the exercise date
equal to the aggregate  exercise  price,  or (c) a combination of the foregoing.
For this purpose,  the "Fair Market Value" of a share of Common Stock on any day
shall  mean (a) if the  principal  market  for the  Common  Stock is a  national
securities  exchange,  the average of the highest  and lowest  sales  prices per
share of the  Common  Stock on such day as  reported  by such  exchange  or on a
composite tape reflecting  transactions  on such exchange,  (b) if the principal
market for the Common Stock is not a national securities exchange and the Common
Stock is quoted on the National  Association  of  Securities  Dealers  Automated
Quotations  System  ("NASDAQ"),  and (i) if actual  sales price  information  is
available  with  respect to the Common  Stock,  the  average of the  highest and
lowest sales prices per share of the Common Stock on such day on NASDAQ, or (ii)
if such  information is not available,  the average  between the highest bid and
the lowest asked prices per share of Common Stock on such day on NASDAQ,  or (c)
if the  principal  market  for the  Common  Stock is not a  national  securities
exchange  and the  Common  Stock is not  quoted on  NASDAQ,  the  average of the
highest bid and lowest  asked  prices per share for the Common Stock on such day
as reported on the NASDAQ OTC Bulletin  Board  Service or by National  Quotation
Bureau,  Incorporated or a comparable service; provided that if clauses (a), (b)
and (c) of this paragraph are all  inapplicable,  or if no trades have been made
or no quotes are  available  for such day,  the fair market  value of a share of
Common Stock shall be determined by the Board of Directors of the Corporation by
any method  consistent  with  applicable  regulations  adopted  by the  Treasury
Department relating to stock options.

         6. Notwithstanding the foregoing,  this option shall not be exercisable
by the Optionee unless (a) a Registration  Statement under the Securities Act of
1933,  as amended  (the  "Securities  Act") with respect to the shares of Common
Stock to be received  upon the exercise of this option  shall be  effective  and
current at the time of exercise or (b) there is an exemption  from  registration
under the  Securities  Act for the  issuance of the shares of Common  Stock upon
exercise.  The Optionee hereby  represents and warrants to the Corporation that,
unless a Registration Statement is effective and current at the time of exercise
of this  option,  the shares of Common  Stock to be issued upon the  exercise of
this option will be acquired by the Optionee for his own account, for investment
only and not with a view to the resale or  distribution  thereof.  In any event,
the Optionee shall notify the  Corporation of any proposed  resale of the shares
of Common  Stock  issued to him upon  exercise  of this  option.  Any  resale or
distribution  of such shares of Common Stock by him may be made only pursuant to
(i) a  Registration  Statement  under the  Securities Act which is effective and
current  with  respect  to the  shares of Common  Stock  being  sold,  or (ii) a
specific exemption from the registration requirements of the Securities Act, but
in claiming  such  exemption,  the Optionee  shall prior to any offer of sale or
sale of such shares of Common  Stock  provide the  Corporation  with a favorable
written  opinion  of  counsel  satisfactory  to the  Corporation,  in  form  and
substance  satisfactory  to the  Corporation,  as to the  applicability  of such
exemption  to the  proposed  sale  or  distribution.  Such  representations  and
warranties shall also be deemed to be made by the Optionee upon each exercise of
this option.

                                       2
<PAGE>

Nothing  herein  shall be construed as  requiring  the  Corporation  to register
shares subject to this option under the Securities Act.

         7. Notwithstanding  anything herein to the contrary, if at any time the
Corporation  shall determine in its discretion that the listing or qualification
of the shares of Common Stock subject to this option on any securities  exchange
or under any  applicable  law, or the  consent or  approval of any  governmental
agency or  regulatory  body,  is necessary or desirable as a condition of, or in
connection  with,  the  granting of an option,  or the issue of shares of Common
Stock  thereunder,  this option may not be  exercised in whole or in part unless
such  listing,  qualification,  consent or approval  shall have been effected or
obtained free of any conditions not acceptable to the Corporation.

         8. Nothing  herein shall confer upon the Optionee any right to continue
as an  employee of the  Corporation,  its parent or any of its  subsidiaries  or
interfere  in any way  with any  right of the  Corporation,  its  parent  or any
subsidiary to terminate  such  relationship  at any time for any reason  without
liability to the Corporation,  its parent or subsidiaries.  Neither the Optionee
nor his legal  representatives  shall have any of the rights or  privileges of a
shareholder of the Corporation in respect of any of the shares issuable upon the
exercise of this option, unless and until certificates  representing such shares
shall  have been  issued  and  delivered;  provided,  however,  that  until such
certificates are issued,  the Optionee shall be treated as owning any previously
acquired shares of Common Stock used to exercise such option.

         9. The  Corporation  may withhold cash and/or shares of Common Stock in
the amount,  if any,  necessary to satisfy its  obligations to withhold taxes or
other amounts by reason of the grant,  exercise or  disposition of the option or
the shares of Common Stock underlying the option, or may require the Optionee to
pay the Corporation  such amount.  The Optionee agrees to pay any such amount to
the Corporation in cash upon demand.

         10. The Corporation may affix appropriate legends upon the certificates
for shares and may issue such "stop transfer" instructions to its transfer agent
in respect of such shares as it determines,  in its discretion,  to be necessary
or appropriate  to (a) prevent a violation of, or to perfect an exemption  from,
the  registration  requirements  of the  Securities  Act, or (b)  implement  the
provisions  of any  agreement  between the  Corporation  and the  Optionee  with
respect to such shares.

         11. The  Optionee  represents  and agrees  that he will comply with all
applicable  laws  relating  to the grant and  exercise  of this  option  and the
disposition of the shares of Common Stock acquired upon exercise of this option,
including without limitation, Federal and state securities and "blue sky" laws.

         12. This option is not  transferable by the Optionee other than by will
or the laws of  descent  and  distribution  and may be  exercisable  during  the
Optionee's  lifetime  only by him, or his legal  representatives.  Neither  this
option  nor  any  of  the  rights  and  privileges  conferred  hereby  shall  be
transferred, assigned, pledged (as collateral for a loan, or as security for the
performance of an obligation,  or for any other purpose), or hypothecated in any
way (whether  voluntarily,  by operation of law or  otherwise)  or be subject to
execution,  attachment, or similar process. Any attempted transfer,  assignment,
pledge (as  collateral  for a loan or as  security  for the  performance  of any
obligation, or for any other purpose),  hypothecation,  execution, attachment or
similar process shall be null and void and of no force or effect.

                                       3
<PAGE>

         13. In the event that,  prior to the issuance by the Corporation of all
the shares pursuant to this option, there shall be any change in the outstanding
Common  Stock of the  Corporation  by reason of a stock  dividend,  stock split,
spin-off, stock combination,  recapitalization,  merger in which the Corporation
is the surviving  corporation or the like, the remaining  number of shares still
subject to this option and the exercise price  therefor shall be  proportionally
adjusted by the Board of  Directors of the  Corporation  to reflect such change.
Such adjustment may provide for the elimination of fractional shares which might
otherwise be subject to options,  without payment therefor. The determination of
the Board of Directors  with respect  thereto shall be conclusive and binding on
the parties.  Notwithstanding  anything herein to the contrary,  in the event of
(a) the  liquidation or dissolution of the  Corporation or (b) a merger in which
the Corporation is not the surviving  corporation or a  consolidation  involving
the  Corporation,  this option shall  terminate,  unless other provision is made
therefor in the transaction.

         14. The  invalidity,  unenforceability  or  illegality of any provision
herein shall not affect the  validity,  enforceability  or legality of any other
provision.

         15. This  Agreement  shall be binding  upon and inure to the benefit of
any  successor  or  assign  of the  Corporation  and to any  heir,  distributee,
executor,   administrator  or  legal  representative  entitled  by  law  to  the
Optionee's rights hereunder. This Agreement may not be amended except in writing
signed by the parties.

         16.  Whenever  notice is  required  to be given under the terms of this
Agreement, such notice shall be in writing and shall be deemed delivered:

            (a) if to the Corporation,  upon receipt by the Corporation,  at the
Corporation's  address set forth  above,  Attention:  Compensation/Stock  Option
Committee,  or such other address as the  Corporation may designate by notice to
the Optionee, effective upon receipt of such notice by the Optionee.

            (b) if to the Optionee, as of the day it is personally delivered, or
5 days after mailing, by registered or certified mail, return receipt requested,
postage  prepaid,  at the  Optionee's  address  set forth  above,  or such other
address as the Optionee may  designate by notice to the  Corporation,  effective
upon receipt of such notice by the Corporation.

         17. This  Agreement  shall be governed by and  construed in  accordance
with the laws of the State of New  Jersey,  without  regard to  conflict  of law
provisions.

         18. This Agreement  constitutes  the entire  understanding  between the
parties  with  respect to the subject  matter  hereof and  supersedes  any prior
agreements with respect thereto.

         19. The  Corporation  shall pay all issuance  taxes with respect to the
shares of Common  Stock upon  exercise of this  option,  as well as all expenses
incurred by the Corporation in connection therewith.

         20.  This  option  shall  not be  construed  or  interpreted  with  any
presumption  against the Corporation by reason of the  Corporation  causing this
Agreement to be drafted.

principal amount of $1,500,000;

         WHEREAS, on January 10, 2000, GTECH and On-Point announced the
execution of an Agreement and Plan of Merger, dated as of January 7, 2000 (the

whereby GTECH would acquire On-Point;

         WHEREAS, on February 23, 2000, On-Point announced the need for a

financials, GTECH terminated the Merger Agreement;

         WHEREAS, GTECH and On-Point subsequently reopened discussions about a

pursue further a merger between GTECH and On-Point;

may have that survive the April 7, 2000, termination of the Merger Agreement;

such rights it might otherwise have, together with GTECH's agreement to amend
the Note as set forth herein, constitutes good and valuable consideration

Releasors have, own or hold, or might have had, owned or held, formerly had or
might have had, individually, representatively, derivatively or in any other
capacity which arise out of, are based upon or relate to GTECH's relationship,
either direct or indirect, with On-Point, including without limitation the

TECHNOLOGY SYSTEMS, INC., ET AL. (Case No. 00-CV-812BTM (S.D. Cal.)), AHRENS, ET

<PAGE>

SANDVICK, ET AL. (Case No. 001403 BTM (S.D. Cal.)) (the "Actions"); (ii) the
proposed settlements of the Actions; (iii) any of the acts, facts, events,
circumstances, matters, claims, transactions, occurrences, omissions,
representations, misrepresentations, or matters of any kind or nature
whatsoever, related directly or indirectly to the subject matters referred
to, set forth in, or the facts or claims for relief which were or could have

therewith.

          (b)  GTECH Releasors acknowledge that they may have sustained
damages, expenses and losses in connection with GTECH Claims which are
presently unknown or not suspected ("GTECH UNKNOWN CLAIMS"), and that such
damages, expenses and losses, if any, might give rise to additional damages,
expenses or losses in the future which are not now anticipated by them, or
might have affected their decision to release the On-Point Releasees. Except
as otherwise provided in Section 1 and 4 of this Agreement, GTECH Releasors
expressly stipulate and agree that, as to any and all GTECH Claims, upon
execution of this Agreement, they shall expressly waive and relinquish, to
the fullest extent permitted by law, any and all provisions, rights and
benefits that they may have under any law of any state or territory  of the
United States, or principle of common law, which would limit the effect of
this Agreement, including the provisions of Section 1542 of the California
Civil Code, to the extent deemed applicable, which provides as follows:

                      Section 1542. GENERAL RELEASE; EXTINGUISHED A general
                      release does not extend to claims which the creditor
                      does not know or suspect to exist in his favor at
                      the time of executing the release, which if known by
                      him must have materially affected his settlement with
                      the debtor.

          (c)  GTECH Releasors acknowledge that they may hereafter discover
facts in addition to or different from those which they now know or believe
to be true with respect to the subject matter of the GTECH Claims, but,
except as provided in Sections 1 and 4 of this Agreement, they intend to and
shall be deemed to have fully, finally and forever settled and released any
and all GTECH Claims, known or unknown, suspected or unsuspected, contingent
or non-contingent, whether or not concealed or hidden, which now exist, or
heretofore have existed upon any theory of law or equity now existing or
coming into existence in the future.

          3. RELEASE BY ON-POINT

          (a)  Except as otherwise provided in Section 4 of this Agreement,

otherwise provided in Section 4 of this Agreement, On-Point Releasors
expressly stipulate and agree that, as to any and all On-Point Claims,upon
execution of this Agreement, they shall expressly waive and relinquish, to

rights and benefits that they may have under any law of any state or
territory of the United States, or principle of common law, which would limit
the effect of this Agreement to those claims actually known or suspected to
exist at the time of execution of this Agreement, including the provisions of
Section 1542 of the California Civil Code, to the extent deemed applicable,
which provides as follows:

                   Section 1542. GENERAL RELEASE; EXTINGUISHED A general
                   release does not extend to claims which the creditor does
                   not know or suspect to exist in his favor at the time of
                   executing the release, which if known by him must have
                   materially affected his settlement with the debtor.

         (c) On-Point Releasors acknowledge that they may hereafter discover
facts in addition to or different from those which they now know or believe
to be true with respect to the subject matter of the On-Point Claims, but,
except as otherwise provided in Section 4 of this Agreement, they intend to
and shall be deemed to have fully, finally and forever settled and released
any and all On-Point Claims, known or unknown, suspected or unsuspected,
contingent or non-contingent, whether or not concealed or hidden, which now
exist, or heretofore have existed upon any theory of law or equity now
existing or coming into existence in the future.

         4. OTHER CONTINUING AGREEMENTS. Notwithstanding the releases set
forth in Sections 2 and 3 hereof, the Ordinary Course Agreements and any
confidentiality agreement entered into between the parties shall continue in
full force and effect in accordance with the provisions thereof.

         5. MISCELLANEOUS. This Agreement shall be construed in accordance
with and governed by the internal law of the State of New York (without
reference to its rules as to conflict of laws), except for Section 1 hereof
which shall be construed in accordance with and governed by the internal law
of the State of California (without reference to its rules as to conflict of
laws). The section headings herein are for convenience only and shall not
affect the construction hereof. This Agreement may be executed in one or more
counterparts but all such separate counterparts shall constitute one and the
same instrument; provided that, although executed in counterparts, the
executed signature pages of each such counterpart may be affixed to a single
copy of this Agreement which shall constitute an original.
