ITEM 5.  OTHER EVENTS.

         On December 1, 1997, AXENT Technologies, Inc. ("AXENT") and Raptor
Systems, Inc. ("Raptor") announced that they have entered into an Agreement and
Plan of Merger dated as of December 1, 1997 (the "Merger Agreement"), which is
filed herewith as EXHIBIT 2.1 and incorporated herein by reference, pursuant to
which Axquisition Two, Inc., a wholly-owned subsidiary of AXENT, will merge with
and into Raptor (the "Merger") with Raptor being the surviving company.

         Under the terms of the Merger Agreement, each outstanding share of
Raptor common stock, $.01 par value per share, will be exchanged for .8 of a
share of AXENT common stock, $.02 par value per share, outstanding Raptor stock
options will be exchanged for AXENT stock options (adjusted for the exchange
ratio) and Raptor will become a wholly-owned subsidiary of AXENT. The
transaction will be accounted for as a pooling-of-interests. The Merger, which
has been unanimously approved by the Boards of Directors of each of AXENT and
Raptor and is expected to be consummated sometime in the first quarter of 1998,
is subject to numerous closing conditions, including the approval of the
shareholders of both AXENT and Raptor.

                          AGREEMENT AND PLAN OF MERGER

         THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") entered into as of
December 1, 1997 by and among AXENT TECHNOLOGIES, INC., a Delaware corporation
("Axent"), AXQUISITION TWO, INC., a Delaware corporation and a wholly-owned
subsidiary of Axent (the "Transitory Subsidiary"), and RAPTOR SYSTEMS, INC., a
Delaware corporation ("Raptor"). Axent, the Transitory Subsidiary and Raptor are
referred to collectively herein as the "Parties."

         This Agreement contemplates a merger of the Transitory Subsidiary with
and into Raptor in a transaction that will qualify under Section 368(a) of the
Code (as defined below). In such merger, the shareholders of Raptor will receive
capital stock of Axent in exchange for their capital stock of Raptor.

         NOW, THEREFORE, in consideration of the representations, warranties,
agreements and covenants herein contained, the Parties agree as follows.

                                    ARTICLE I
                                   THE MERGER

         1.1   THE MERGER.

         Upon and subject to the terms and conditions of this Agreement, the
Transitory Subsidiary shall merge with and into Raptor (with such merger
referred to herein as the "Merger") at the Effective Time (as defined below).
From and after the Effective Time, the separate corporate existence of the
Transitory Subsidiary shall cease and Raptor shall continue as the surviving
corporation in the Merger (the "Surviving Corporation"). The "Effective Time"
shall be the time at which Raptor and the Transitory Subsidiary file the
certificate of merger prepared and executed in accordance with the relevant
provisions of the Delaware General Corporation Law (the "Certificate of Merger")
with the Secretary of State of the State of Delaware. The Merger shall have the
effects specified in this Agreement and in Section 259 of the Delaware General
Corporation Law.

         1.2   THE CLOSING.

         The closing of the transactions contemplated by this Agreement (the
"Closing") shall take place at the offices of Piper & Marbury, L.L.P., 1200
Nineteenth Street, N.W., Washington, D.C., commencing at 10:00 a.m. local time
on January 31, 1998, or, if all of the conditions to the obligations of the
Parties to consummate the transactions contemplated hereby have not been
satisfied or waived by such date, on such mutually agreeable later date as soon
as practicable after the satisfaction or waiver of all conditions to the
obligations of the Parties to consummate

                                     - 1 -

<PAGE>   8


the transactions contemplated hereby, but in no event later than ten days
following such satisfaction or waiver of such conditions (the "Closing Date").

         1.3   ACTIONS AT OR CONCURRENTLY WITH THE CLOSING.

         At the Closing, (a) Raptor shall deliver to Axent and the Transitory
Subsidiary the various certificates, instruments and documents referred to in
Section 5.2, (b) Axent and the Transitory Subsidiary shall deliver to Raptor the
various certificates, instruments and documents referred to in Section 5.3, and
(c) Axent shall deliver certificates for the Merger Shares (as defined below) to
Boston EquiServ LP as exchange agent (the "Exchange Agent") in accordance with
Section 1.6. At or concurrently with the Closing, the parties hereto shall cause
the Merger to be consummated by filing a Certificate of Merger with the
Secretary of State of the State of Delaware, in accordance with the relevant
provisions of the Delaware General Corporation Law. 

         1.4 ADDITIONAL ACTION.

         The Surviving Corporation may, at any time after the Effective Time,
take any action, including executing and delivering any document, in the name
and on behalf of either Raptor or the Transitory Subsidiary, in order to
consummate the transactions contemplated by this Agreement.

         1.5   CONVERSION OF SHARES.

         As of the Effective Time, by virtue of the Merger and without any
action on the part of the holder of any shares of common stock, $.01 par value,
of Raptor ("Raptor Common Stock") or capital stock of the Transitory Subsidiary:

               (a)   Each issued and outstanding share of the capital stock of
         the Transitory Subsidiary shall be converted into and become one fully
         paid and nonassessable share of common stock, $.01 par value, of the
         Surviving Corporation.

               (b)   Any shares of Raptor Common Stock owned by Axent or the
         Transitory Subsidiary shall be canceled and retired and shall cease to
         exist, and no stock of Axent or other consideration shall be delivered
         in exchange therefor. All shares of common stock, $.02 par value, of
         Axent ("Axent Common Stock") owned by Raptor shall remain unaffected by
         the Merger.

               (c)   Subject to Section 1.6, each issued and outstanding share
         of Raptor Common Stock (other than shares to be canceled in accordance
         with Section 1.5(b)) shall be converted into the right to receive
         eight-tenths (.80) (the "Exchange Ratio") of a fully paid and
         nonassessable share of Axent Common Stock (all such stock received in
         such conversion, the "Merger Shares") (which amount will be adjusted
         for any stock split or stock dividend with respect to the Axent Common
         Stock or Raptor Common Stock effected between the date of this
         Agreement and the Effective Time). All such shares of


                                      - 2-

<PAGE>   9


         Raptor Common Stock, when so converted, shall no longer be outstanding
         and shall automatically be canceled and retired and shall cease to
         exist, and each holder of a certificate representing any such shares
         shall cease to have any rights with respect thereto, except the right
         to receive Axent Common Stock and any cash in lieu of fractional shares
         of Axent Common Stock to be issued or paid in consideration therefor
         upon the surrender of such certificate in accordance with Section 1.6,
         without interest.

         1.6   EXCHANGE OF SHARES.

               (a)   "Raptor Shareholders" means the holders of the Raptor
         Common Stock.

               "Raptor Shares" means shares of Raptor's equity securities
         actually held by each Raptor Shareholder.

               (b)   Prior to the Effective Time, Axent shall appoint the
         Exchange Agent to effect the exchange for the Merger Shares of
         certificates that, immediately prior to the Effective Time, represented
         Raptor Shares converted into Merger Shares pursuant to Section 1.5
         ("Certificates"). On the Closing Date, Axent shall deliver to the
         Exchange Agent, in trust for the benefit of holders of Certificates, a
         stock certificate (issued in the name of the Exchange Agent or its
         nominee) representing the Merger Shares, as described in Section
         1.5(c). Within thirty (30) days after the Effective Time, Axent shall
         cause the Exchange Agent to send a notice and a transmittal form to
         each holder of a Certificate advising such holder of the effectiveness
         of the Merger and the procedure for surrendering to the Exchange Agent
         such Certificate in exchange for the Merger Shares issuable pursuant to
         Section 1.5(c). Each holder of a Certificate, upon proper surrender
         thereof to the Exchange Agent in accordance with the instructions in
         such notice, shall be entitled to receive in exchange therefor (subject
         to any taxes required to be withheld) the Merger Shares issuable
         pursuant to Section 1.5(c). Until properly surrendered, each such
         Certificate shall be deemed for all purposes to evidence only the right
         to receive the Merger Shares issuable pursuant to Section 1.5(c).
         Holders of Certificates shall not be entitled to receive certificates
         for the Merger Shares to which they would otherwise be entitled until
         such Certificates are properly surrendered.

               (c)   If any Merger Shares are to be issued in the name of a
         person other than the person in whose name the Certificate surrendered
         in exchange therefor is registered, it shall be a condition to the
         issuance of such Merger Shares that (i) the Certificate so surrendered
         shall be transferable, and shall be properly assigned, endorsed or
         accompanied by appropriate stock powers, (ii) such transfer shall
         otherwise be proper and (iii) the person requesting such transfer shall
         pay to the Exchange Agent any transfer or other taxes payable by reason
         of the foregoing or establish to the satisfaction of the Exchange Agent
         that such taxes have been paid or are not required to be paid.
         Notwithstanding the foregoing, neither the Exchange Agent nor any Party
         shall be liable to a holder of Raptor Shares for any Merger Shares
         issuable to such holder pursuant to

                                     - 3 -


<PAGE>   10


         Section 1.5(c) that are delivered to a public official pursuant to
         applicable abandoned property, escheat or similar laws.

               (d)   In the event any Certificate shall have been lost, stolen
         or destroyed, upon the making of an affidavit of that fact by the
         person claiming such Certificate to be lost, stolen or destroyed, Axent
         shall issue in exchange for such lost, stolen or destroyed Certificate
         the Merger Shares issuable in exchange therefor pursuant to Section
         1.5(c). The Board of Directors of Axent may, in its discretion and as a
         condition precedent to the issuance thereof, require the owner of such
         lost, stolen or destroyed Certificate to submit to Axent an affidavit,
         to give to Axent an indemnity against any claim that may be made
         against Axent with respect to the Certificate alleged to have been
         lost, stolen or destroyed, and to provide such other assurances and
         execute such other instruments as the Exchange Agent may require.

               (e)   Promptly following the date which is twelve months after
         the Closing Date, the Exchange Agent shall return to Axent all Merger
         Shares in its possession, and the Exchange Agent's duties shall
         terminate. Thereafter, each holder of a Certificate may surrender such
         Certificate to Axent and, subject to applicable abandoned property,
         escheat and similar laws, receive in exchange therefor the Merger
         Shares issuable with respect thereto pursuant to Section 1.5(c).


         1.7   DIVIDENDS.

         No dividends or other distributions that are payable to the holders of
record of Axent Common Stock as of a date on or after the Closing Date shall be
paid to former Raptor Shareholders entitled by reason of the Merger to receive
Merger Shares until such holders surrender their Certificates in accordance with
Section 1.6. Upon such surrender, Axent shall pay or deliver to the persons in
whose name the certificates representing such Merger Shares are issued any
dividends or other distributions that are payable to the holders of record of
Axent Common Stock as of a date on or after the Closing Date and which were paid
or delivered between the Effective Time and the time of such surrender; provided
that no such person shall be entitled to receive any interest on such dividends
or other distributions.


         1.8   FRACTIONAL SHARES.

         No certificates or scrip representing fractional Merger Shares shall be
issued to former Raptor Shareholders upon the surrender for exchange of
Certificates, and such former Raptor Shareholders shall not be entitled to any
voting rights, rights to receive any dividends or distributions or other rights
as a stockholder of Axent with respect to any fractional Merger Shares that
would otherwise be issued to such former Raptor Shareholders. In lieu of any
fractional Merger Shares that would otherwise be issued, each former Raptor
Shareholder that would have been entitled to receive a fractional Merger Share
shall, upon proper surrender of such person's Certificates, receive a cash
payment equal to the average of the last reported sale prices of Axent Common
Stock on The NASDAQ National Market for the ten (10) trading days




                                      - 4-

<PAGE>   11

immediately preceding the Effective Time multiplied by the fraction of a share
that such Raptor Shareholder would otherwise be entitled to receive. The
fractional share interests of each former holder of Raptor Common Stock will be
aggregated, and no former holder of Raptor Common Stock will receive cash in an
amount greater than or equal to the value of one full share of Axent Common
Stock.

         1.9 OPTIONS.

               (a)   As of the Effective Time, all options to purchase Raptor
         Shares issued by Raptor pursuant to its 1995 Stock Option and Grant
         Plan, as amended and restated (the "Raptor Stock Option Plan"), or
         pursuant to the resolution of Raptor's Board of Directors or the
         Compensation Committee thereof ("Options"), whether vested, unvested or
         subject to repurchase by Raptor following such exercise, which are
         outstanding and not exercised immediately prior to the Effective Time,
         shall be exchanged for options for Axent Common Stock to be issued by
         Axent. Axent and Raptor shall enter into the Stock Option Exchange
         Agreement in the form attached hereto as EXHIBIT G. Immediately after
         the Effective Time, each Option outstanding immediately prior to the
         Effective Time shall be deemed to constitute an option to acquire, on
         the same terms and conditions as were applicable under such Option
         immediately prior to the Effective Time, such number of shares of Axent
         Common Stock as is equal to the number of Raptor Shares subject to the
         unexercised portion of such Option multiplied by the Exchange Ratio
         (with any fraction resulting from such multiplication to be rounded
         down to the next lower whole number). The exercise price per share of
         each such exchanged Option shall be equal to the exercise price of such
         Option immediately prior to the Effective Time, divided by the Exchange
         Ratio (with any fraction of a cent resulting from such division to be
         rounded up to the next higher whole cent). Except for any acceleration
         and termination, the term, exercisability (including any acceleration
         of exercisability as a result of this transaction), vesting schedule,
         repurchase provisions, status as an "incentive stock option" under
         Section 422 of the Internal Revenue Code of 1986 (as amended, the
         "Code"), if applicable, and all of the other terms of the Options in
         effect immediately prior to the Effective Time and after giving effect
         to any acceleration of vesting for such Options as a result of this
         transaction shall otherwise remain unchanged. Axent acknowledges that
         the unvested Options are subject to automatic acceleration of vesting
         pursuant to the terms of the Raptor Stock Option Plan and related
         agreements as a result of the consummation of this transaction.

               (b)   As soon as practicable after the Effective Time, Axent or
         the Surviving Corporation shall deliver to the holders of Options
         appropriate notices setting forth such holders' rights pursuant to such
         Options, as amended by this Section 1.9, and the agreements evidencing
         such Options shall continue in effect on the same terms and conditions
         (subject to the amendments provided for in this Section 1.9 and such
         notice).


                                     - 5 -

<PAGE>   12


               (c)   Axent shall take all corporate action necessary to reserve
         for issuance a sufficient number of shares of Axent Common Stock for
         delivery upon exercise of the Options exchanged in accordance with this
         Section 1.9. As soon as practicable after the Effective Time, and in
         any event no later than 30 days after the Closing, Axent shall file a
         Registration Statement on Form S-8 (or any successor form) under the
         Securities Act of 1933 (as amended, the "Securities Act") with respect
         to all shares of Axent Common Stock subject to such Options, and shall
         use its best efforts to maintain the effectiveness of such Registration
         Statement for so long as such Options remain outstanding.

               (d)   Axent's obligations for each Option pursuant to this
         Section 1.9 shall be subject to the execution and delivery, to the
         extent required, by the holder of such Option, a consent, in the form
         of the Stock Option Exchange Agreements, to the terms hereof. Raptor
         shall use its best efforts to obtain, prior to the Closing, the consent
         from each holder of an Option to the amendment of such Option pursuant
         to this Section 1.9.

         1.10  CERTIFICATE OF INCORPORATION.

         The Certificate of Incorporation of Raptor shall be amended and
restated substantially in the form set forth in EXHIBIT A hereto and, as so
amended and restated, shall be the Certificate of Incorporation of the Surviving

         1.11  BY-LAWS.

         The By-laws of the Surviving Corporation shall be amended and restated
substantially in the form set forth in EXHIBIT B hereto and, as so amended and
restated, shall be the By-laws of the Surviving Corporation.

         1.12  DIRECTORS AND OFFICERS.

         The directors of the Transitory Subsidiary shall become the directors
of the Surviving Corporation after the Effective Time. The officers of the
Transitory Subsidiary immediately prior to the Effective Time shall become the
initial officers of the Surviving Corporation after the Effective Time, in each
case until their respective successors are duly elected or appointed.

         1.13  NO FURTHER RIGHTS.

         From and after the Effective Time, no Raptor Shares shall be deemed to
be outstanding, and holders of Certificates shall cease to have any rights with
respect thereto, except as provided herein or by law.

         1.14  CLOSING OF TRANSFER BOOKS.

         At the Effective Time, the stock transfer books of Raptor shall be
closed and no transfer of Raptor Shares shall thereafter be made. If, after the
Effective Time, Certificates are presented


                                     - 6 -

to the Surviving Corporation or the Exchange Agent, they shall be canceled and
exchanged for Merger Shares in accordance with Section 1.5(c).

         grant, extend, accelerate the vesting of or enter into any such option,
         warrant, equity security, call, right, commitment or agreement, and, to

         2.5   SUBSIDIARIES.

         Except as disclosed by Raptor in its most recent Raptor Report (as
defined in Section 2.6 below) as required by Item 601 of Regulation S-K under
the Securities Act, and except as set forth in Section 2.5 of the Disclosure
Schedule, Raptor does not have the power, directly or indirectly, to vote or
direct the voting of, securities sufficient to elect the majority of the
directors of any corporation (a "Subsidiary") and does not control, directly or
indirectly, or have any direct or indirect controlling equity interest, or any
commitment to acquire any such direct or indirect controlling equity interest,
in any corporation, partnership, joint venture, association, trust, or other
business organization. Each Subsidiary is a corporation duly organized, validly
existing and in corporate good standing (to the extent such good standing is
recognized in the jurisdiction of incorporation) under the laws of the
jurisdiction of its incorporation. Each Subsidiary has the requisite corporate
power and authority to carry on the businesses in which it is engaged and to own
and use the properties owned and used by it. Raptor has delivered or made
available to Axent correct and complete copies of the charter of each
Subsidiary, as amended to date, and prior to Closing will deliver or make
available to Axent correct and complete copies of the By-laws of each
Subsidiary, as amended to date. No Subsidiary is in default under or in

outstanding shares of capital stock of each Subsidiary are duly authorized,
validly issued, fully paid, nonassessable and free of


                                     - 9 -

<PAGE>   16

preemptive rights. All shares of each Subsidiary that are held of record or
owned beneficially by either Raptor or any Subsidiary or any nominee are held or
owned free and clear of any restrictions on transfer (other than restrictions
under the Securities Act, state securities laws or foreign securities laws),
written claims, Security Interests, options, warrants, rights, contracts and
calls. There are no outstanding or authorized options, warrants, rights,
agreements or commitments to which Raptor or any Subsidiary is a party or which
are binding on any of them providing for the issuance, disposition or
acquisition of any capital stock of any Subsidiary. There are no outstanding
stock appreciation, phantom stock or similar rights with respect to any
Subsidiary.

         2.6   FINANCIAL STATEMENTS.

         Raptor has previously furnished or made available to Axent complete and
accurate copies, as amended or supplemented, of its (a) Registration Statement
on Form S-1 which was declared effective by the SEC on February 6, 1996, and (b)
all other reports filed by Raptor under Sections 13, 14 or 15(d) of the
Securities Exchange Act of 1934 (the "Exchange Act") with the SEC since February
6, 1996 (such reports are collectively referred to herein as the "Raptor
Reports"). The Raptor Reports constitute all of the documents required to be
filed by Raptor under Sections 13, 14 or 15(d) of the Exchange Act with the SEC.
As of their respective dates, the Raptor Reports complied in all material
respects with applicable SEC and NASDAQ requirements and did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. The audited financial
statements and unaudited interim financial statements of Raptor included in the
Raptor Reports (i) complied as to form in all material respects with then
applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto, (ii) have been prepared in accordance with GAAP
applied on a consistent basis throughout the periods covered thereby (except as
may be indicated therein or in the notes thereto, and in the case of quarterly
financial statements, as permitted by Form 10-Q under the Exchange Act), (iii)
fairly present the consolidated financial condition, results of operations and
cash flows of Raptor as of the respective dates thereof and for the periods
referred to therein, and (iv) are consistent with the books and records of
Raptor.

         2.7   ABSENCE OF CERTAIN MATERIAL ADVERSE CHANGES.

         Since September 30, 1997, there has not been any material adverse
change in the assets, business, financial condition or results of operations of
Raptor and its Subsidiaries (taken as a whole), nor has there occurred any event
which should reasonably be foreseen to result in such a material adverse change
in the future.

         2.8   UNDISCLOSED LIABILITIES.

         Neither Raptor nor its Subsidiaries has any liability (whether known or
unknown, whether absolute or contingent, whether liquidated or unliquidated and
whether due or to become


                                     - 10 -

<PAGE>   17

due), except for (a) liabilities accrued or reserved against the September 30,
1997 unaudited consolidated balance sheet of Raptor and its Subsidiaries
("Raptor Most Recent Balance Sheet"), (b) liabilities which have arisen since
September 30, 1997 in the Ordinary Course of Business, (c) contractual or
statutory liabilities incurred in the Ordinary Course of Business which are not
required by GAAP to be reflected on a balance sheet, (d) liabilities disclosed
in Section 2.8 of the Disclosure Schedule, and (e) liabilities adequately
reserved against or disclosed in writing.

         2.9   TAX MATTERS.

               (a)   Except as set forth in Section 2.9 of the Disclosure
         Schedule, Raptor and its Subsidiaries has filed all Tax Returns (as
         defined below) that it was required to file and all such Tax Returns
         were correct and complete in all material respects. Each of Raptor and
         its Subsidiaries has paid or will pay all Taxes (as defined below) that
         are due on or before the Closing Date, whether or not shown on any such
         Tax Returns, except such as are being contested in good faith by
         appropriate proceedings (to the extent any such proceedings are
         required) and with respect to which Raptor is maintaining reserves
         adequate for their payment. The accrued but unpaid Taxes of Raptor and
         its Subsidiaries for Tax Periods through the date of the Raptor Most
         Recent Balance Sheet do not exceed the accruals and reserves for Taxes
         (other than deferred Taxes) set forth on the Raptor Most Recent Balance
         Sheet. Neither Raptor nor any of its Subsidiaries has any actual or, to
         their knowledge, potential liability for any Tax obligation of any
         taxpayer (including without limitation any affiliated group of
         corporations or other entities that included Raptor during a prior
         period) other than Raptor. All Taxes that Raptor or any of its
         Subsidiaries is or was required by law to withhold or collect have been
         duly withheld or collected and, to the extent required, have been paid
         to the proper Governmental Entity.

                     (i)   For purposes of this Agreement, "Taxes" means all
               taxes, charges, fees, levies or other similar assessments or
               liabilities, including without limitation income, gross receipts,
               ad valorem, premium, value-added, excise, real property, personal
               property, sales, use, transfer, withholding, employment, payroll
               and franchise taxes imposed by the United States of America or
               any state, local or foreign government, or any agency thereof, or
               other political subdivision of the United States or any such
               government, and any interest, fines, penalties, assessments or
               additions to tax resulting from, attributable to or incurred in
               connection with any tax or any contest or dispute thereof and any
               amounts of Taxes of another person that Raptor or any of its
               Subsidiaries, or Axent or any of its Subsidiaries, as applicable,

                      (iii)  For purposes of determining the amount of Taxes
               attributable to a specified period (e.g., the period from the
               date of the Raptor Most Recent Balance Sheet through the Closing
               Date) other than a Tax Period, each Tax shall be computed as if
               the specified period were a Tax Period. For purposes of this
               paragraph (iii), a Tax Period means a period for which a Tax is
               required to be computed under applicable statues and regulations.

               (b)   No examination or audit or any Tax Returns of Raptor or any
         of its Subsidiaries by any Governmental Entity is currently in progress
         or, to the actual knowledge of Raptor, threatened or contemplated.
         Raptor has not waived any statute of limitations with respect to taxes
         or agreed to an extension of time with respect to a tax assessment or
         deficiency.

               (c)   Raptor is not a "consenting corporation" within the meaning
         of Section 341(f) of the Code and none of the assets of Raptor are
         subject to an election under Section 341(f) of the Code. Raptor is not
         a party to any Tax allocation or sharing agreement, other than an
         agreement to which only Raptor and its Subsidiaries are parties.

               (d)   Raptor is not and has never been a member of an "affiliated
         group" of corporations (within the meaning of Section 1504 of the
         Code), other than a group of which only Raptor and its Subsidiaries are
         members.

               (e)   Raptor has not taken or agreed to take any action that
         would prevent the Merger from constituting a tax-free reorganization
         under the provisions of Section 368(a) of the Code.

         2.10  ASSETS.

         Each of Raptor and its Subsidiaries has good and marketable title to
all tangible assets necessary for the conduct of its businesses as presently
conducted. Each such tangible asset is free from material defects, has been
maintained in accordance with normal industry practice, is in good operating
condition and repair (subject to normal wear and tear) and is suitable for the
purposes for which it presently is used. No asset of Raptor (tangible or
intangible) is subject to any Security Interest, except the following: (a) liens
shown on the Raptor Most Recent Balance Sheet securing specified liabilities or
obligations with respect to which no material default exists (or event that,
whether with or without notice, lapse of time, or the happening or occurrence of
any other event would constitute a default); (b) exceptions disclosed in Section
2.10 of the Disclosure Schedule; and (c) liens for current taxes not yet due and
payable for which adequate reserves have been provided.

         2.11  OWNED REAL PROPERTY.

         Neither Raptor nor any of its Subsidiaries owns any real property.

         distributors that grant non-exclusive rights to use, resell or
         sublicense a Raptor product in accordance with customary industry
         practices on customary terms.

         lists all written licenses, sublicenses and other agreements as to
         which Raptor or any of its Subsidiaries is a party and pursuant to
         which Raptor is authorized to use any third party patents, patent

         including software ("Third Party Intellectual Property Rights") which
         are incorporated in any existing product or service of Raptor, other
         than shrink-wrap licenses.

         of its Subsidiaries has provided or agreed to provide source code of

         all such patents, registrations, applications (owned by Raptor), and
         all licenses, sublicenses and agreements referred to above and as

               (b)   With respect to each item of Intellectual Property that
         Raptor or any of its Subsidiaries owns: (i) other than common law
         trademarks, Intellectual Property subject to joint development rights
         or other rights that will not materially interfere with the conduct of
         the business of Raptor, and subject to such rights as have been granted
         by Raptor or any of its Subsidiaries under license agreements entered
         into by Raptor (copies of which have previously been made available or
         disclosed in writing to Axent), Raptor or its Subsidiaries possesses
         all right, title and interest in and to such item; and (ii) such item

         time would constitute a breach or default by Raptor or any of its
         Subsidiaries or permit termination, modification or acceleration
         thereunder by the other party thereto; (iii) the underlying item of
         Third Party Intellectual Property is not subject to any outstanding
         judgment, order, decree, stipulation or injunction to which Raptor or
         any of its Subsidiaries is a party or has been specifically named that
         materially interferes with the conduct of Raptor's business as
         currently conducted, nor to Raptor's knowledge subject to any other
         outstanding judgment, order, decree, stipulation, or injunction that
         materially interferes with the conduct of Raptor's business as
         currently conducted.

               (c)   Except as set forth in Section 2.12 of the Disclosure
         Schedule and to Raptor's knowledge with respect to patent rights,
         neither Raptor nor any of its Subsidiaries (i) has been named in any

from January 1, 1997 through August 31, 1997, neither Raptor nor any of its
Subsidiaries has breached, or received in writing any claim or threat that it
has breached, any of the terms or conditions of any material agreement, contract
or commitment to which it is a party or by which any of its assets are bound

respect to a particular claim or any such policy in general.

         2.16  LITIGATION.

         operations of Raptor and its Subsidiaries taken as a whole.

               (b)   Raptor has provided or has made available to Axent any

         Raptor has provided Axent with a written list of the annual rate of

         complete and accurate list of all Employee Benefit Plans (as defined
         below) maintained, or contributed to, by Raptor or any ERISA Affiliate
         (as defined below). For purposes of this Agreement, "Employee Benefit
         Plan" means any "employee pension benefit plan" (as defined in Section

         benefits, deferred compensation, bonuses, stock options, stock
         purchase, phantom stock, stock appreciation or other forms of incentive
         compensation or post-retirement compensation. For purposes of this
         Agreement, "ERISA Affiliate" means any entity which is a member of (i)
         a controlled group of corporations (as defined in Section 414(b) of the
         Code), (ii) a group of trades or businesses under common control (as
         defined in Section 414(c) of the Code), or (iii) an affiliated service
         group (as defined under Section 414(m) of the Code or the regulations
         under Section 414(o) of the Code), any of which includes Raptor.
         Complete and accurate copies of (i) all Employee Benefit Plans which

         years for each Employee Benefit Plan, have been delivered or made
         available to Axent or will prior to Closing be delivered or made
         available to Axent. Each Employee Benefit Plan has been administered in
         accordance with its terms and each of Raptor and the ERISA Affiliates
         has met its obligations with respect to such Employee Benefit Plan and
         has made all required contributions thereto. Raptor and all Employee
         Benefit Plans are in compliance with the currently applicable
         provisions of ERISA and the Code and the regulations thereunder.

               (b)   There are no investigations by any Governmental Entity,
         termination proceedings or other claims (except claims for benefits
         payable in the normal operation of the Employee Benefit Plans and
         proceedings with respect to qualified domestic relations orders), suits
         or proceedings against or involving any Employee Benefit Plan or
         asserting any rights or claims to benefits under any Employee Benefit
         Plan that could give rise to any liability.

               (c)   All the Employee Benefit Plans that are intended to be
         qualified under Section 401(a) of the Code have received determination,
         opinion or notification letters from the Internal Revenue Service to
         the effect that such Employee Benefit Plans are qualified and the plans
         and the trusts related thereto are exempt from federal income taxes


                                     - 17 -

<PAGE>   24

         under Sections 401(a) and 501(a), respectively, of the Code, no such
         determination, opinion or notification letter has been revoked and
         revocation has not been threatened, and no such Employee Benefit Plan
         has been amended since the date of its most recent determination,
         opinion or notification letter or application therefor in any respect,
         and no act or omission has occurred, that would adversely affect its
         qualification or increase its cost.

               (d)   Neither Raptor nor any ERISA Affiliate has ever maintained
         an Employee Benefit Plan subject to Section 412 of the Code or Title IV
         of ERISA.

               (e)   At no time has Raptor or any ERISA Affiliate been obligated
         to contribute to any "multi-employer plan" (as defined in Section
         4001(a)(3) of ERISA).

               (f)   There are no unfunded obligations under any Employee
         Benefit Plan providing benefits after termination of employment to any
         employee of Raptor (or to any beneficiary of any such employee),
         including but not limited to retiree health coverage and deferred
         compensation, but excluding continuation of health coverage required to
         be continued under Section 4980B of the Code, any applicable state
         health insurance continuation law and any state insurance conversion
         privileges law.

               (g)   No act or omission has occurred and no condition exists
         with respect to any Employee Benefit Plan maintained by Raptor or any
         ERISA Affiliate that would subject Raptor or any ERISA Affiliate to any
         fine, penalty, tax or liability of any kind imposed under ERISA or the
         Code.

               (h)   No Employee Benefit Plan is funded by, associated with, or
         related to a "voluntary employee's beneficiary association" within the
         meaning of Section 501(c)(9) of the Code.

               (i)   No Employee Benefit Plan, plan documentation or agreement,
         summary plan description or other written communication distributed
         generally to employees by its terms prohibits Raptor from amending or
         terminating any such Employee Benefit Plan.

               (j)   Except as set forth in Section 2.18 of the Disclosure
         Schedule, there is no: (i) written agreement with any director,
         executive officer or other key employee of Raptor or any of its
         Subsidiaries which has not been terminated in accordance with its terms
         (A) the benefits of which are contingent, or the terms of which are
         altered, upon the occurrence of a transaction involving Raptor or any
         of its Subsidiaries of the nature of any of the transactions
         contemplated by this Agreement, (B) providing any term of employment or
         compensation guarantee or (C) providing severance benefits or other
         benefits after the termination of employment of such director,
         executive officer or key employee; (ii) agreement, plan or arrangement
         under which any person may receive payments from Raptor or any of its
         Subsidiaries that may be subject to the tax imposed

                                     - 18 -

         by Section 4999 of the Code or included in the determination of such
         person's "excess parachute payment" under Section 280G of the Code; and
         (iii) agreement or plan binding Raptor or any of its Subsidiaries,
         including without limitation any stock option plan, stock appreciation
         right plan, restricted stock plan, stock purchase plan, severance
         benefit plan, or any Employee Benefit Plan, any of the benefits of
         which will be increased, or the vesting of the benefits of which will
         be accelerated, by the occurrence of any of the transactions
         contemplated by this Agreement or the value of any of the benefits of
         which will be calculated on the basis of any of the transactions
         contemplated by this Agreement.

         2.19  ENVIRONMENTAL MATTERS.

               (a)   Each of Raptor and its Subsidiaries has complied with all
         applicable Environmental Laws (as defined below). Except as disclosed
         in the Raptor Reports and since September 30, 1997, there is no pending
         or, to the knowledge of Raptor, threatened civil or criminal
         litigation, written notice of violation, formal administrative
         proceeding, or investigation, inquiry or information request by any
         Governmental Entity, relating to any Environmental Law involving Raptor
         or any of its Subsidiaries. For purposes of this Agreement,
         "Environmental Law" means any federal, state or local law, statute,
         rule or regulation or the common law relating to the environment or
         occupational health and safety, including without limitation any
         statute, regulation or order pertaining to (i) treatment, storage,
         disposal, generation and transportation of toxic or hazardous
         substances or solid or hazardous waste; (ii) air, water and noise
         pollution; (iii) groundwater and soil contamination; (iv) the release
         or threatened release into the environment of toxic or hazardous
         substances, or solid or hazardous waste, including without limitation
         emissions, discharges, injections, spills, escapes or dumping of
         pollutants, contaminants or chemicals; (v) the protection of wild life,
         marine sanctuaries and wetlands, including without limitation all
         endangered and threatened species; (vi) storage tanks, vessels and
         containers; (vii) underground and other storage tanks or vessels,
         abandoned, disposed or discarded barrels, containers and other closed
         receptacles; (viii) health and safety of employees and other persons;
         and (ix) manufacture, processing, use, distribution, treatment,
         storage, disposal, transportation or handling of pollutants,
         contaminants, chemicals or industrial, toxic or hazardous substances or
         oil or petroleum products or solid or hazardous waste. As used above,
         the terms "release" and "environment" shall have the meaning set forth
         in the federal Comprehensive Environmental Compensation, Liability and
         Response Act of 1980 ("CERCLA").

                (b)  There have been no releases of any Materials of
         Environmental Concern (as defined below) into the environment at any
         parcel of real property or any facility when owned, operated or
         controlled by Raptor or any of its Subsidiaries for which Raptor or any
         of its Subsidiaries should have liability under the Environmental Laws.
         Raptor is not aware of any other releases of Materials of Environmental
         Concern that could reasonably be expected to have an impact on the real
         property or facilities owned, operated or controlled by Raptor or a
         Subsidiary. For purposes of this Agreement,


                                     - 19 -

<PAGE>   26

         "Materials of Environmental Concern" means any chemicals, pollutants or
         contaminants, hazardous substances (as such term is defined under
         CERCLA), solid wastes and hazardous wastes (as such terms are defined
         under the federal Resources Conservation and Recovery Act), toxic
         materials, oil or petroleum and petroleum products, or any other
         material subject to regulation under any Environmental Law.

         2.20  LEGAL COMPLIANCE.

         Each of Raptor and its Subsidiaries, and the conduct and operations of
their respective businesses, is in compliance with each law (including rules and

its Subsidiaries to conduct its business as currently conducted (including
without limitation those issued or required under applicable export laws or
regulations) ("Permits"). Each such Permit is in full force and effect and, to
the knowledge of Raptor, no suspension or cancellation of such Permit is
threatened and to Raptor's knowledge there is no basis for believing that such
Permit will not be renewable upon expiration.

         2.22  CERTAIN BUSINESS RELATIONSHIPS WITH AFFILIATES.

         Except as set forth in the Raptor Reports, as disclosed in Section 2.22

         2.23  FEES.

         Except as disclosed in Section 2.23 of the Disclosure Schedule or

banking firm, finder or agent with respect to the transactions contemplated by
this Agreement.

         The minute books of Raptor and each of its Subsidiaries contain true
and complete records of all actions taken at any meetings of Raptor's or such
Subsidiary's shareholders, Board of Directors or any committee thereof and of
all written consents executed in lieu of the holding of any such meeting. The
financial books and records of Raptor and each of its Subsidiaries accurately
reflect in all material respects the assets, liabilities, business, financial

accordance with good business and bookkeeping practices.

         2.25  POOLING.

         Neither Raptor nor any of its Affiliates (as defined below) has through
the date of this Agreement taken or agreed to take any action that could impair
the ability of Axent to account for the business combination to be effected by
the Merger as a "pooling of interests" in accordance with GAAP. "Affiliate"
shall have the meaning set forth in Rule 12b-2 under the Exchange Act, as
amended.

         2.26  COMPANY ACTION.

         The Board of Directors of Raptor, at a meeting duly called and held,
has by the unanimous vote of all directors (i) determined that the Merger is
fair and in the best interests of Raptor and its shareholders, (ii) adopted this
Agreement in accordance with the provisions of the Delaware General Corporation
Law, and (iii) directed that this Agreement and the Merger be submitted to
Raptor Shareholders for their adoption and approval and resolved to recommend
that Raptor Shareholders vote in favor of the adoption of this Agreement and the
approval of the Merger.

         2.27  DISCLOSURE.

         No representation or warranty by Raptor contained in this Agreement,
and no statement contained in any document, certificate or other instrument
delivered to or to be delivered by or on behalf of Raptor pursuant to this
Agreement, contains or will contain any untrue statement of a material fact or
omits or will omit to state any material fact necessary, in light of the
circumstances under which it was or will be made, in order to make the
statements herein or therein not misleading.

         2.28  FAIRNESS OPINION.

         Raptor has received a written fairness opinion from NationsBanc
Montgomery Securities, Inc., its financial advisor, to the effect that the
Merger is fair to the holders of the Raptor Common Stock from a financial point
of view, and that Raptor has delivered a true and complete copy of such opinion
to Axent.

bankruptcy, insolvency or other similar laws affecting the enforcement of
creditors' rights and remedies generally, and except that the availability of
equitable remedies, including specific performance, is subject to the discretion
of the court before which any proceeding therefor may be brought.

         3.4   NONCONTRAVENTION.

Exchange Act, (iv) the filing of the Certificate of Merger as required by the
Delaware General Corporation Law, and (v) the filing with the SEC, the NMS and

the Securities Act, except as set forth in Section 3.5 of the Disclosure
Schedule and other than the Transitory Subsidiary, Axent has no Subsidiaries and
does not control directly or indirectly or have any direct or indirect equity
controlling interest, or any commitment to acquire any such direct or indirect
controlling equity interest, in any corporation, partnership, joint venture,
association, trust, or other business organization. Each Subsidiary is a
corporation duly organized, validly existing and in corporate good standing (to
the extent such good standing is recognized in the jurisdiction of
incorporation) under the laws of the jurisdiction of its incorporation. Each
Subsidiary has the requisite corporate power and authority to carry on the
businesses in which it is engaged and to own and use the properties owned and
used by it. Prior to the Closing, Axent will deliver or make available to Raptor
correct and complete copies of the charter and By-laws of each Subsidiary, as

provision of its charter or By-laws. All of the issued and outstanding shares of
capital stock of each Subsidiary are duly authorized, validly issued, fully
paid, nonassessable and free of preemptive rights. All shares of each Subsidiary

laws or foreign securities laws), written claims, Security Interests, options,
warrants, rights, contracts and calls. There are no outstanding or authorized
options, warrants, rights, agreements or commitments to which Axent or any of
its Subsidiaries is a party or which are binding on any of them providing for
the issuance, disposition or acquisition of any capital stock of any Subsidiary.
There are no outstanding stock appreciation, phantom stock or similar rights
with respect to any Subsidiary.

         3.6   REPORTS AND FINANCIAL STATEMENTS.

         Axent has previously furnished or made available to Raptor complete and
accurate copies, as amended or supplemented, of its (a) Registration Statement
on Form S-1 which was declared effective by the SEC on April 23, 1996, and (b)
all other reports filed by Axent under Sections 13, 14 or 15(d) of the Exchange
Act with the SEC since April 23, 1996 (such reports are collectively referred to
herein as the "Axent Reports"). The Axent Reports constitute all of the


                                     - 23 -

<PAGE>   31

documents required to be filed by Axent under Sections 13, 14 or 15(d) of the
Exchange Act with the SEC. As of their respective dates, the Axent Reports
complied in all material respects with applicable SEC and NASDAQ requirements
and did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The audited financial statements and unaudited interim financial
statements of Axent included in the Axent Reports (i) complied as to form in all
material respects with then applicable accounting requirements and the published
rules and regulations of the SEC with respect thereto, (ii) have been prepared
in accordance with GAAP applied on a consistent basis throughout the periods
covered thereby (except as may be indicated therein or in the notes thereto, and
in the case of quarterly financial statements, as permitted by Form 10-Q under
the Exchange Act), (iii) fairly present the consolidated financial condition,
results of operations and cash flows of Axent as of the respective dates thereof
and for the periods referred to therein, and (iv) are consistent with the books
and records of Axent.

         3.7   ABSENCE OF MATERIAL ADVERSE CHANGES.

         Since September 30, 1997, there has not been any material adverse
change in the assets, business, financial condition or results of operations of
Axent and its Subsidiaries (taken as a whole), nor has there occurred any event
which should reasonably be foreseen to result in such a material adverse change
in the future.

         3.8   UNDISCLOSED LIABILITIES.

         Neither Axent nor any of its Subsidiaries has any liability (whether
known or unknown, whether absolute or contingent, whether liquidated or
unliquidated and whether due or to become due), except for (a) liabilities
accrued or reserved against the September 30, 1997 unaudited consolidated
balance sheet of Axent and its Subsidiaries ("Axent Most Recent Balance Sheet"),
(b) liabilities which have arisen since September 30, 1997 in the Ordinary
Course of Business, (c) contractual or statutory liabilities incurred in the
Ordinary Course of Business which are not required by GAAP to be reflected on a
balance sheet, and (d) liabilities disclosed in Section 3.8 of the Disclosure
Schedule.

         3.9   TAX MATTERS.

               (a)   Except as set forth in Section 3.9 if the Disclosure
         Schedule, Axent and its Subsidiaries have filed all Tax Returns that it
         was required to file and all such Tax Returns were correct and complete
         in all material respects. Each of Axent and its Subsidiaries has paid
         or will pay all Taxes that are due on or before the Closing Date,
         whether or not shown on any such Tax Returns, except such as are being
         contested in good faith by appropriate proceedings (to the extent any
         such proceedings are required) and with respect to which Axent is
         maintaining reserves adequate for their payment. The accrued but unpaid
         Taxes of Axent and its Subsidiaries for Tax Periods through the date of
         the Axent Most Recent Balance Sheet do not exceed the accruals and
         reserves for


                                     - 25 -

<PAGE>   32


         Taxes (other than deferred Taxes) set forth on the Axent Most Recent
         Balance Sheet. Neither Axent nor any of its Subsidiaries has any actual
         or, to their knowledge, potential liability for any Tax obligation of
         any taxpayer (including without limitation any affiliated group of
         corporations or other entities that included Axent during a prior
         period) other than Axent. All Taxes that Axent or any Subsidiary is or
         was required by law to withhold or collect have been duly withheld or
         collected and, to the extent required, have been paid to the proper
         Governmental Entity.

               (b)   For purposes of determining the amount of Taxes
         attributable to a specified period (e.g., the period from the date of
         the Axent Most Recent Balance Sheet through the Closing Date) other
         than a Tax Period, each Tax shall be computed as if the specified
         period were a Tax Period. For purposes of this paragraph (b), a Tax
         Period means a period for which a Tax is required to be computed under
         applicable statutes and regulations.

               (c)   No examination or audit of any Tax Returns of Axent or any
         of its Subsidiaries by any Governmental Entity is currently in progress
         or, to the actual knowledge of Axent threatened or contemplated. Axent
         has not waived any statute of limitations with respect to taxes or
         agreed to an extension of time with respect to a tax assessment or
         deficiency.

               (d)   Axent is not a "consenting corporation" within the meaning
         of Section 341(f) of the Code and none of the assets of Axent is
         subject to an election under Section 341(f) of the Code. Axent is not a
         party to any Tax allocation or sharing agreement other than an
         agreement to which only Axent and its Subsidiaries are parties.

               (e)   Axent has never been a member of an "affiliated group" of
         corporations (within the meaning of Section 1504 of the Code) other
         than (i) a group of which only Axent and its Subsidiaries are members
         or (ii) a group including Raxco Software, Inc. and its Subsidiaries.

               (f)   Axent has not taken or agreed to take any action that would
         prevent the Merger from constituting a tax-free reorganization under
         the provisions of Section 368(a) of the Code.

         3.10  ASSETS.

         Each of Axent and its Subsidiaries has good and marketable title to all
tangible assets necessary for the conduct of its businesses as presently
conducted. Each such tangible asset is free from material defects, has been
maintained in accordance with normal industry practice, is in good operating
condition and repair (subject to normal wear and tear) and is suitable for the
purposes for which it presently is used. No asset of Axent (tangible or
intangible) is subject to any Security Interest, except the following: (a) liens
shown on the Axent Most Recent Balance


                                     - 26 -

Sheet securing specified liabilities or obligations with respect to which no
material default exists (or event that, whether with or without notice, lapse of
time, or the happening or occurrence of any other event would constitute a
default); (b) exceptions disclosed in Section 3.10 of the Disclosure Schedule;
and (c) liens for current taxes not yet due and payable for which adequate
reserves have been provided.

         3.11  OWNED REAL PROPERTY.

         Neither Axent nor any of its Subsidiaries owns any real property.

         3.12  INTELLECTUAL PROPERTY.

         Other than as expressly set forth in this Section 3.12, only with
respect to Axent's Omniguard product line:

               (a)   Each of Axent and its Subsidiaries owns, or is licensed or
         otherwise possesses legally enforceable rights to use, all items of
         Intellectual Property that are used to conduct its business as
         currently conducted or planned by Axent to be conducted. Axent has
         taken reasonable measures to protect the proprietary nature of each
         item of Intellectual Property that it considers confidential, and to
         maintain in confidence all trade secrets and confidential information
         that it presently owns or uses.

         terms and each of Axent and the ERISA Affiliates has met its
         obligations with respect to such Employee Benefit Plan and has made all
         required contributions thereto. Axent and all Employee Benefit Plans
         are in compliance with the currently applicable provisions of ERISA and
         the Code and the regulations thereunder.

               (b)   There are no investigations by any Governmental Entity,

         proceedings with respect to qualified domestic relations orders), suits
         or proceedings against or involving any Employee Benefit Plan or
         asserting any rights or claims to benefits under any Employee Benefit
         Plan that could give rise to any liability.

         qualified under Section 401(a) of the Code have received determination,
         opinion or notification letters from the Internal Revenue Service to
         the effect that such Employee Benefit Plans are qualified and the plans
         and the trusts related thereto are exempt from federal income taxes
         under Sections 401(a) and 501(a), respectively, of the Code, no such
         determination, opinion or notification letter has been revoked and
         revocation has not been threatened, and no such Employee Benefit Plan
         has been amended since the date of its most recent determination,
         opinion or notification letter or application therefor in any respect,
         and no act or omission has occurred, that would adversely affect its
         qualification or increase its cost.

               (d)   Neither Axent nor any ERISA Affiliate has ever maintained
         an Employee Benefit Plan subject to Section 412 of the Code or Title IV

         to contribute to any "multi-employer plan" (as defined in Section
         4001(a)(3) of ERISA).

               (f)   There are no unfunded obligations under any Employee
         Benefit Plan providing benefits after termination of employment to any
         employee of Axent (or to any beneficiary of any such employee),
         including but not limited to retiree health coverage and deferred
         compensation, but excluding continuation of health coverage required to
         be continued under Section 4980B of the Code, any applicable state
         health insurance continuation law and any state insurance conversion
         privileges law.

               (g)   No act or omission has occurred and no condition exists
         with respect to any Employee Benefit Plan maintained by Axent or any
         ERISA Affiliate that would subject Axent or any ERISA Affiliate to any
         fine, penalty, tax or liability of any kind imposed under ERISA or the
         Code.

               (h)   No Employee Benefit Plan is funded by, associated with, or
         related to a "voluntary employee's beneficiary association" within the
         meaning of Section 501(c)(9) of the Code.

               (i)   No Employee Benefit Plan, plan documentation or agreement,
         summary plan description or other written communication distributed
         generally to employees by its terms prohibits Axent from amending or
         terminating any such Employee Benefit Plan.

               (j)   Except as set forth in Section 3.18 of the Disclosure
         Schedule, there is no: (i) written agreement with any director,

         guarantee or (C) providing severance benefits or other benefits after
         the termination of employment of such director, executive officer or
         key employee; (ii) agreement, plan or arrangement under which any
         person may receive payments from Axent or any of its Subsidiaries that
         may be subject to the tax imposed by Section 4999 of the Code or
         included in the determination of such person's "excess parachute
         payment" under Section 280G of the Code; and (iii) agreement or plan
         binding Axent or any of its Subsidiaries, including without limitation
         any stock option plan, stock appreciation right plan, restricted stock
         plan, stock purchase plan, severance benefit plan, or any Employee
         Benefit Plan, any of the benefits of which will be increased, or the
         vesting of the benefits of which will be accelerated, by the occurrence
         of any of the transactions contemplated by this Agreement or the value
         of any of the benefits of which will be calculated on the basis of any
         of the transactions contemplated by this Agreement.

         within five business days prepare and file with the SEC under the
         Securities Act a registration statement on Form S-4 (such registration
         statement, together with any amendments or supplements thereto, the
         "Registration Statement"), in which the Proxy Statement will be
         included as a prospectus in connection with the registration under the
         Securities Act of the Axent Common Stock. Raptor and Axent will cause
         the Proxy Statement and the Registration Statement to comply as to form
         in all material respects with the applicable provisions of the
         Securities Act, the Exchange Act and the rules and regulations
         thereunder. Each of Raptor and Axent shall furnish all information
         about itself and its business and operations and all necessary
         financial information to the other as the other may reasonably request
         in connection with the preparation of the Proxy Statement and the
         Registration Statement. Axent will use its reasonable best efforts, and
         Raptor will cooperate with it, to have the Registration Statement
         declared effective by the SEC as promptly as practicable (including
         clearing the Proxy Statement with the SEC). Each of Raptor and Axent
         agrees promptly to correct any information provided by it for use in
         the Proxy Statement and the Registration Statement if and to the extent
         that such information shall have become false or misleading in any
         material respect, and each of the parties hereto further agrees to take
         all steps necessary to amend or supplement the Proxy Statement and the
         Registration Statement, and to cause the Proxy Statement and the
         Registration Statement as so amended or supplemented to be filed with
         the SEC and to be disseminated to their respective stockholders, in
         each case as to the extent required by applicable federal and state
         securities laws. Each of Raptor and Axent agrees that the information
         provided by it for inclusion in the Proxy Statement or the Registration
         Statement and each amendment or supplement thereto, at the time of
         mailing thereof and, at-the time of respective meetings of stockholders
         of Raptor and Axent, will not include an untrue statement of a material
         fact or omit to state a material fact required to be stated therein or
         necessary to make the statement therein, in light of the circumstances
         under which they were made, not misleading. Axent will advise Raptor
         and deliver copies (if any) to Raptor, promptly after it receives
         notice thereof, of any request by the SEC for amendment of the Proxy
         Statement or the Registration Statement or comments thereon and
         responses thereto or requests by the SEC for additional information
         (regardless of whether such requests relate to Raptor or Axent), and
         Axent shall promptly notify Raptor of (i) the time when the
         Registration Statement has become effective, (ii) or any supplement or
         amendment has been filed, (iii) the issuance of any stop order and (iv)
         the suspension of the qualification and registration of the Axent
         Common Stock issuable in connection with the Merger. Axent and Raptor
         shall also take any and all such actions as may be necessary or as it
         may deem advisable for the purpose of complying with all applicable
         state securities laws in connection with the offering and issuance of
         the Merger Shares.

               (b)   Promptly following the resolution to the satisfaction of
         the SEC of all SEC comments on the Prospectus/Proxy Statement (or the
         expiration of applicable waiting period if no SEC comments are received
         by such date), each of Raptor and Axent shall distribute the
         Prospectus/Proxy Statement to their shareholders and, pursuant thereto,

         their shareholders to vote in favor of the adoption of this Agreement
         and the approval of the Merger at the Raptor Special Meeting and the

         proxies thereunder, and the calling and holding of Axent Special
         Meeting. Subject to Raptor's right to withdraw or modify its
         recommendation as set forth in Section 6.1(g), Axent, acting through
         its Board of Directors, shall include in the Prospectus/Proxy Statement

         4.9 EXCLUSIVITY.

               (a)   Raptor agrees that, from and after the date of this
         Agreement until the earlier of the Effective Time or the termination of
         this Agreement in accordance with Section 6.1, it shall not, directly
         or indirectly, through any (A) officer, (B) director, (C) employee, (D)
         affiliate that has signed an Affiliate's Agreement (as defined in
         Section 4.10) (a "Specified Affiliate"), (E) any agent or
         representative of a Specified Affiliate, (F) any agent or
         representative of Raptor that Raptor controls, and it shall direct any
         other agent or representative not to, (i) solicit, initiate, or
         encourage any inquiries or proposals that constitute, or could
         reasonably be expected to lead to, any Acquisition Proposal (as defined
         below), (ii) engage in negotiations or discussions concerning, or
         provide any non-public information to any person or entity relating to,
         any Acquisition Proposal, or (iii) agree to, approve or recommend any

         through representatives or agents on behalf of the Board, from (A)
         furnishing non-public information to, or entering into discussion or
         negotiations with, any person or entity in connection with an
         unsolicited bona fide written Acquisition Proposal by such person or
         entity or recommending such an unsolicited bona fide written
         Acquisition Proposal to the stockholders of Raptor, if and only to the
         extent that (1) such Acquisition Proposal would, if consummated, result
         in a transaction that would, in the reasonable good faith judgment of
         the Board of Directors of Raptor, after consultation with its financial
         advisors, result in a transaction more favorable to Raptor's
         stockholders from a financial point of view (including consideration
         of, among other matters, the ability of the person or entity making
         such proposal to obtain any financing necessary for the Acquisition
         Proposal) than the Merger (any such more favorable Acquisition Proposal
         being referred to in this Agreement as a "Superior Proposal"), (2) such
         action is necessary, in the reasonable good faith judgment of the Board
         of Directors of Raptor after consultation with outside corporate
         counsel to Raptor, in order to comply with the fiduciary duties of
         Raptor's Directors to Raptor's stockholders under Delaware law, and (3)
         prior to furnishing such non-public information to, or entering into
         discussions or negotiations with, such person or entity, Raptor's Board
         of Directors receives from such person or entity an executed
         confidentiality agreement with confidentiality provisions not
         materially less favorable to such party than those contained in Section
         4.15 of this Agreement; or (B) complying with Rule 14d-9 and Rule 14e-2
         promulgated under the Exchange Act or other applicable law with regard
         to an Acquisition Proposal.

               (b)   As used herein, the term "Acquisition Proposal" shall mean
         any proposed or actual (i) merger consolidation or similar transaction
         involving Raptor, (ii) sale, lease or other disposition, directly or
         indirectly, by merger, consolidation, share exchange or otherwise, of
         any assets of Raptor representing 20% or more of the assets of Raptor,
         (iii) issue, sale or other disposition of (including by way of merger,
         consolidation, share exchange or any similar transaction) securities
         (or options, rights or warrants to purchase or securities convertible
         into, such securities) representing 20% or more of the votes

         attached to the outstanding securities of Raptor, (iv) transaction in
         which any person shall acquire beneficial ownership (as such term is
         defined in Rule 13d-3 under the Exchange Act), or the right to acquire
         beneficial ownership, or any "group" (as such term is defined under the
         Exchange Act) shall have been formed which beneficially owns or has the
         right to acquire beneficial ownership of, 20% or more of the
         outstanding shares of Raptor Common Stock, (v) liquidation,
         dissolution, or other similar type of transaction with respect to
         Raptor, or (vi) transaction which is similar in form, substance or
         purpose to any of the foregoing transactions, provided, however, that
         the term "Acquisition Proposal" shall not include the Merger and the
         transactions contemplated thereby.

               (c)   Raptor shall notify Axent no later than 24 hours after
         receipt by Raptor (or its advisors), of any Acquisition Proposal or any
         request for nonpublic information in connection with an Acquisition
         Proposal or for access to the properties, books or records of Raptor by
         any person or entity that informs Raptor that it is considering making,
         or has made, an Acquisition Proposal (the "Acquisition Proposal"). Such
         notice to the Axent shall be made orally and in writing and shall
         indicate reasonable detail the identity of the Acquisition Proposal and
         the terms and conditions of such proposal, inquiry or contact. If the
         financial terms of such Acquisition Proposal are materially modified,
         then Raptor shall notify Axent of the terms and conditions of such
         modification within 24 hours of the receipt of such modification.

         4.10  POOLING ACCOUNTING; AGREEMENTS FROM AFFILIATES.

               (a)   Axent and Raptor shall each use its best efforts to cause
         the business combination to be effected by the Merger to be accounted
         for as a pooling of interests. Each of Axent and Raptor shall use its
         best efforts to cause its respective Affiliates not to take any action
         that would adversely affect the ability of Axent to account for the
         business combination to be effected by the Merger as a pooling of
         interests.

               (b)   Concurrently with the execution of this Agreement, Raptor
         shall deliver to Axent a list of all persons or entities who are at
         such time Affiliates of Raptor (the "Raptor Affiliates"). In order to
         help ensure that the issuance of Merger Shares will comply with the
         Securities Act and that the Merger will be accorded pooling of interest
         accounting treatment, Raptor shall cause each Raptor Affiliate to
         execute and deliver to Axent on or before the date of this Agreement, a
         written agreement substantially in the form attached hereto as EXHIBIT
         C (the "Raptor Affiliate's Agreement").

         other Shareholders as are listed in Section 4.10(c) of the Disclosure
         Schedule to execute and deliver to Raptor on or

<PAGE>   51

         Subsidiaries, unless such modification is required after the Effective

         (collectively, the "Indemnified Parties") against any costs or expenses
         (including reasonable attorneys' fees), judgments, fines, losses,
         claims, damages, liabilities and amounts paid in settlement in
         connection with any actual or threatened claim, action, suit,
         proceeding or investigation, whether civil, criminal, administrative or
         investigative (collectively, "Actions"), (x) arising out of or
         pertaining to the transactions contemplated by this Agreement, or (y)
         otherwise with respect to any acts or omissions occurring at or prior
         to the Effective Time, in each case to the same extent (including any
         provision for the advancement of expenses) as provided in Raptor's
         Certificate of Incorporation or By-laws or any written agreements
         between Raptor and any such Indemnified Party regarding indemnification
         as in effect on the date hereof, in each case for a period of six years
         after the Effective Time; provided, however, that, in the event that
         any claim or claims for indemnification are asserted or made within
         such six-year period, all rights to indemnification in respect of any
         such claim or claims shall continue until the disposition of any and
         all such claims. In the event of any such Action (whether arising
         before or after the Effective Time), the Indemnified Parties shall
         promptly notify Axent or the Surviving Corporation in writing, but the
         failure to so notify shall not relieve Axent or the Surviving
         Corporation of its obligations under this Section 4.19(b) except to the
         extent it is materially prejudiced by such failure, and Axent or the
         Surviving Corporation shall have the right to assume the defense
         thereof (unless legal counsel for such Indemnified Party shall in good
         faith determine that such assumption would give rise to a conflict of
         interest), including the employment of counsel reasonably satisfactory
         to such Indemnified Parties. The Indemnified Parties shall have the
         right to employ separate joint counsel in any such Action and to
         participate in (but not control unless such legal counsel for the
         Indemnified Party shall in good faith determine that Axent or the
         Surviving Corporation's participation in such Action has given rise to
         a conflict of interest) the defense thereof, and the fees and expenses
         of such counsel shall be at the expense of Axent or the Surviving
         Corporation in the event that legal counsel for the Indemnified Parties
         shall in good faith determine that Axent or the Surviving Corporation's
         participation in such Action has given rise to a conflict of interest.
         In the

                                     - 45 -

         event that legal counsel for the Indemnified Parties determines in good
         faith that a conflict of interest exists among the Indemnified Parties,
         each Indemnified Party to which such conflict of interest applies shall
         have the right to retain separate counsel and the fees and expenses of
         such separate counsel shall be paid by Axent or the Surviving
         Corporation. After the Effective Time, Axent or the Surviving
         Corporation shall pay the reasonable fees and expenses of such counsel,
         promptly after statements therefor are received and Axent or the
         Surviving Corporation will cooperate in the defense of any such Action.
         Axent or the Surviving Corporation shall not be liable for any
         settlement of any such Action effected without its written consent.
         Neither Axent nor the Surviving Corporation shall settle any Action
         without the written consent of the relevant Indemnified Parties, which
         consent shall not be unreasonably withheld.

               (c)   Axent and the Surviving Corporation shall honor and fulfill
         in all respects the indemnification obligations of Raptor pursuant to
         indemnification agreements and employment agreements (the employee
         parties under such agreements being referred to as the "Officer
         Employees") with Raptor's directors and officers existing on the date
         hereof.

               (d)   The provisions of this Section 4.19 shall survive the
         consummation of the Merger at the Effective Time, is intended for the
         irrevocable benefit of Raptor, the Surviving Corporation, the
         Indemnified Parties and the Officer Employees as third party
         beneficiaries, shall be binding on all successors and assigns of Axent
         or the Surviving Corporation and shall be enforceable by the
         Indemnified Parties and the Officer Employees.

               (e)   This Section 4.19 is intended for the irrevocable benefit
         of, and to grant third party rights to, the Indemnified Parties and the
         Officer Employees and shall be binding on all successors and assigns of
         Raptor, Axent and the Surviving Corporation. Each of the Indemnified
         Parties and the Officer Employees shall be entitled to enforce the
         covenants contained in this Section 4.19 and Axent acknowledges and
         agrees that each Indemnified Party and Officer Employee would suffer
         irreparable harm and that no adequate remedy at law exists for a breach
         of such covenants.

               (g)      by Raptor, if the Board of Directors of Raptor
         recommends to the holders of Raptor Common Stock approval or acceptance
         of an Acquisition Proposal by a person other than Axent, but only in
         the event that the Board of Directors of Raptor, after consultation
         with and based upon the advice of its legal counsel, has determined in
         good faith that such action is necessary for the Board of Directors of
         Raptor to comply with its fiduciary duties to its stockholders under
         applicable law.


         6.2   EFFECT OF TERMINATION.

               (a)   If this Agreement is terminated (i) by Axent pursuant to
         Section 6.1(f), or (ii) by Raptor pursuant to Section 6.1(c) as a
         result of the failure to receive the requisite vote for adoption of
         this Agreement and approval of the Merger by the stockholders of Raptor
         at the Raptor Stockholders Meeting, or (iii) by Raptor pursuant to
         Section 6.1(g) or (iv) by Axent pursuant to Section 6.1(c) as a result
         of the failure to receive the requisite vote for adoption of this
         Agreement and approval of the Merger by the stockholders of Raptor at
         the Raptor Stockholders Meeting, and, in the case of a termination by
         Axent pursuant to Section 6.1(c) or by Raptor pursuant to Section
         6.1(c) at the time of the event giving rise to the right of Axent to
         terminate under such Section 6.1(c) or the right of Raptor to terminate
         under such Section 6.1(c), an Acquisition Proposal involving Raptor
         shall have been announced or proposed which shall not have been
         absolutely and unconditionally withdrawn and abandoned and Raptor shall
         subsequently consummated such Acquisition Proposal within 270 days of
         the termination of this Agreement, Raptor shall pay in cash to Axent a
         termination fee equal to $8,850,316 (the "Raptor Termination Fee").

               (b)   The Raptor Termination Fee shall be paid in cash in
         immediately available funds. If the Raptor Termination Fee is triggered
         by a right to terminate this Agreement pursuant to Sections 6.1(f) or
         6.1(g), such fee shall be paid prior to and as a condition precedent to
         the effectiveness of such termination. If the Raptor Termination Fee is
         triggered by the right to terminate this Agreement pursuant to Section
         6.1(c), such fee shall be paid prior to and as a condition precedent to
         the consummation of such Acquisition Proposal.

               (c)   In no event shall Raptor be required to pay to Axent any
         Raptor Termination Fee, if, immediately prior to the applicable
         termination of this Agreement, Axent was in material breach of any of
         its material obligations under this Agreement.

               (d)   If one party fails to promptly pay to the other any fee or
         expense due hereunder, the defaulting party shall pay the costs and
         expenses (including reasonable documented legal fees and expenses) in
         connection with any action, including the filing of any lawsuit or
         other legal action, taken to collect payment, together with interest on
         the amount of any unpaid fee at the publicly announced prime rate of
         Citibank, N.A. from the date such fee was required to be paid.

FOR IMMEDIATE RELEASE


                         AXENT AND RAPTOR AGREE TO MERGE

       COMBINATION DELIVERS UNMATCHED ENTERPRISE SECURITY FROM ONE SOURCE

ROCKVILLE, MD, DECEMBER 1, -- AXENT Technologies, Inc. (NASDAQ: AXNT), a leading
provider of enterprise security management solutions, and Raptor Systems, Inc.
(NASDAQ: RAPT), a leading network security vendor, jointly announced today that
they have signed a definitive merger agreement. The union of these two security
leaders will combine AXENT's industry leading OmniGuard(R) suite of enterprise
security management solutions with Raptor's highly regarded, award-winning
Eagle(R) network security products. The combined companies will operate as AXENT
Technologies, Inc. and offer customers worldwide the broadest, most
comprehensive family of enterprise security products and services in the
industry.

Under terms of the merger agreement, AXENT will offer 0.80 shares of its common
stock for each outstanding share of Raptor's stock and will exchange stock
options using the same ratio. AXENT expects to issue approximately 12.8 million
shares to Raptor stockholders and option holders, resulting in a transaction
value of approximately $250 million. The merger agreement has been approved by
the respective Boards of Directors and is expected to close within approximately
90 days, subject to regulatory reviews, approval of each company's stockholders
and other customary closing conditions. The transaction will be accounted for as
a pooling of interests.

The merger will create the first true enterprise security vendor, able to
address the full scope of security issues facing large enterprises, by combining
AXENT's strength in multi-platform, client/server security management, intrusion
detection, remote access security, single sign-on and user administration with
Raptor's leading VPN, web, and intranet/Internet firewall security technologies.
The combined companies' extensive product line will lead the industry,
addressing more aspects of information security than any other vendor. AXENT
intends to provide integration between product lines and provide an enterprise
security console for security management and administration, helping customers
streamline and simplify security across the enterprise. The company will also
continue AXENT's strategy of integrating its security

products with enterprise management solutions from Tivoli, Computer Associates,
Hewlett-Packard and BMC.

"The merger of AXENT and Raptor brings together complementary system and network
security solutions and creates the first company in the industry able to provide
customers and partners one source for enterprise security solutions," said John
Becker, president and CEO of AXENT, who will continue in those positions after
the transaction. "Customers today are overwhelmed by the number of disparate
products and vendors as they address the issues related to securing their
enterprises across complex and distributed computing infrastructures. The merger
now positions AXENT as the ideal security partner for enterprise customers, with
a broad range of products, services and expertise to help them simplify
enterprise security."

"Although Raptor and AXENT are both recognized as leaders in the security
industry we have viewed the security opportunity from a different perspective,"
said Shaun McConnon, president and CEO of Raptor Systems. "AXENT was one of the
first vendors to take on the difficult challenges of providing client/server
security within the enterprise. Raptor on the other hand approached the business
from securing the network. Upon consummation of the merger, AXENT will be the
first vendor that has the foresight, technology and expertise to protect the
entire enterprise, enabling organizations to securely tap burgeoning new
business opportunities of the Internet, intranets and extranets."
