                                                                January 5, 1998
 
Dear Stockholders:
 
  You are cordially invited to attend a Special Meeting of Stockholders of
AXENT Technologies, Inc. to be held at 11:00 a.m. on February 5, 1998 at
AXENT's headquarters at 2400 Research Boulevard, Rockville, Maryland.
 
  At this important meeting, you will be asked to approve the issuance (the
"AXENT Share Proposal") of AXENT common stock (the "AXENT Common Stock") in
connection with the Agreement and Plan of Merger, dated as of December 1, 1997
(the "Merger Agreement"), among AXENT, Axquisition Two, Inc., a Delaware
subsidiary of AXENT ("Merger Subsidiary"), and Raptor Systems, Inc., a
Delaware corporation ("Raptor"). Pursuant to the terms of the Merger
Agreement, Merger Subsidiary will be merged with and into Raptor (the
"Merger"), which will become a wholly-owned subsidiary of AXENT. The
consummation of the Merger will result in, among other things, the conversion
of each outstanding share of common stock of Raptor into 0.80 of a share of
AXENT Common Stock. As a result, the holders of outstanding shares of Raptor
common stock immediately prior to the Merger will become holders of shares of
AXENT Common Stock. Your approval of the AXENT Share Proposal will also result
in approval of the 1998 Raptor Option Exchange Plan (the "Exchange Plan")
under which outstanding options of Raptor will be exchanged for options to
purchase up to 1,878,726 shares of AXENT Common Stock. As a condition of the
Merger, the AXENT Board of Directors (the "AXENT Board") will be appointing
three (3) current Raptor directors to the AXENT Board. These three directors
will fill the vacancies created by the resignations of three current
directors. The proposed Merger is described in the accompanying
Prospectus/Joint Proxy Statement, the forepart of which includes a summary of
the terms of the Merger and certain other information relating to the proposed
transactions. Approval of the Merger and the AXENT Share Proposal requires the
affirmative vote of a majority of votes cast on such matter by the holders of
the outstanding shares of AXENT Common Stock present, in person or by proxy,
at the AXENT Special Meeting.
 
  You will also be asked to (i) approve and adopt AXENT's 1998 Employee Stock
Purchase Plan (the "Stock Purchase Plan") and the reservation of 500,000
shares of AXENT Common Stock for issuance thereunder and (ii) approve and
adopt AXENT's 1998 Incentive Stock Plan (the "Option Plan") and the
reservation of 1,800,000 shares of AXENT Common Stock for issuance thereunder.
Approval of the Stock Purchase Plan and the Option Plan require the
affirmative vote of a majority of votes cast on such matter by the holders of
the outstanding shares of AXENT Common Stock present, in person or by proxy,
at the AXENT Special Meeting.
 
  Broadview Associates LLC ("Broadview") was retained by AXENT to act as its
independent financial advisor in connection with the Merger. As discussed in
the accompanying Prospectus/Joint Proxy Statement, Broadview has delivered to
the AXENT Board of Directors its written opinion as of November 30, 1997, that
the consideration to be paid by AXENT to Raptor stockholders pursuant to the
Merger is fair, from a financial point of view, to AXENT and its stockholders.
The opinion is based on and subject to certain matters stated in the opinion,
which is included as Annex B to the Prospectus/Joint Proxy Statement.
 
  Certain stockholders who as of December 31, 1997, the record date, held in
the aggregate approximately  % of the AXENT Common Stock have entered into
Voting and Support Agreements with Raptor, providing, among other things, for
the appointment of nominees of Raptor as proxies to vote their shares of AXENT
Common Stock to approve the AXENT Share Proposal.
<PAGE>
 
  ON NOVEMBER 30, 1997 YOUR BOARD OF DIRECTORS DETERMINED THAT THE MERGER IS
FAIR TO, AND IN THE BEST INTERESTS OF, AXENT AND ITS STOCKHOLDERS. YOUR BOARD
OF DIRECTORS HAS APPROVED THE TERMS OF THE MERGER AGREEMENT AND THE MERGER BY
UNANIMOUS VOTE AND UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE TO
APPROVE THE AXENT SHARE PROPOSAL. IN ADDITION, YOUR BOARD OF DIRECTORS
RECOMMENDS THAT THE STOCKHOLDERS VOTE TO APPROVE THE STOCK PURCHASE PLAN AND
THE OPTION PLAN.
 
  Information concerning the matters to be considered and voted upon at the
meeting is set forth in the attached Notice of Meeting and Prospectus/Joint
Proxy Statement. It is important that your shares be represented at the
meeting, regardless of the number you hold. Therefore, please sign, date and
return your proxy card as soon as possible, whether or not you plan to attend
the meeting. This will not prevent you from voting your shares in person if
you subsequently choose to attend the meeting.
 
                                          Sincerely,

                                    SUMMARY
 
  The following is a summary of certain information contained elsewhere in this
Prospectus/Joint Proxy Statement. Reference is made to, and this Summary is
qualified in its entirety by, the more detailed information contained in this
Prospectus/Joint Proxy Statement and the Annexes hereto. Unless otherwise
defined herein, capitalized terms used in this Summary have the respective
meanings ascribed to them elsewhere in this Prospectus/Joint Proxy Statement.
Stockholders are urged to read this Prospectus/Joint Proxy Statement and the
Annexes hereto in their entirety.
 
THE COMPANIES
 
  AXENT. AXENT develops, markets, licenses and supports computer security
solutions for enterprise computing environments. AXENT's OmniGuard family is a
suite of software products which provides a comprehensive solution to a wide
range of computer security requirements for enterprise computing platforms.
OmniGuard functions include security assessment, intrusion detection, file
encryption, network encryption, access controls, strong authentication, single
sign-on and security administration. These functions operate across PCs, local
area networks ("LANs"), NT, UNIX, and NetWare servers, mid-range and mainframe
environments and the Internet. AXENT addresses the growing requirement for
comprehensive security solutions as organizations migrate from centralized,
proprietary computing environments to distributed, networked computing
platforms. AXENT believes that enterprise security is best addressed by
providing integrated security functionality across the five domains of
enterprise computing--PC/notebook, server, network, the Internet and the World-
Wide Web. AXENT's OmniGuard products and related consulting services help
organizations to simplify the enterprise security problem while ensuring the
confidentiality and integrity of their corporate data more efficiently and
effectively.
 
  AXENT's OmniGuard family of software products consists of Enterprise Security
Manager ("ESM"), Intruder Alert ("ITA"), Enterprise Access Control ("EAC"),
Defender, Power VPN, UNIX Resource Manager ("URM"), UNIX Privilege Manager
("UPM"), and Enterprise Resource Manager ("ERM"). Each of these products is
available across a variety of enterprise computing platforms. These products
may be used in combination to provide a comprehensive information security
solution for the enterprise or individually to fulfill a specific security
need. OmniGuard can also be combined with a broader systems management strategy
by integrating with systems management platforms such as BMC's Patrol, Hewlett-
Packard's OpenView and Tivoli's Tivoli Management Environment.
 
  As of December 1, 1997, more than 2,000 customers in a broad range of
industries had deployed more than 500,000 copies of the OmniGuard software
products.
 
  AXENT has maintained an active program of expansion through its acquisition
of products and businesses and its exploration of collaborative relationships
throughout its history. As part of its monitoring of possible candidates for
acquisition or collaborative relationship, AXENT has followed Raptor and has
recognized that Raptor's products, technologies and marketing and distribution
channels are complementary to those of AXENT.
 
  On March 25, 1997, AXENT completed the acquisition of AssureNet Pathways,
Inc. ("AssureNet"). AssureNet provided a broad range of network security
solutions that protect enterprise-wide networks from unauthorized entry,
tampering and theft of information and services. AssureNet products are
marketed by AXENT as the OmniGuard/Defender and OmniGuard/Power VPN products.
 
  AXENT's principal executive offices are located at 2400 Research Boulevard,
Suite 200, Rockville, Maryland 20850. Its telephone number is (301) 258-5043.
As used in this Prospectus/Joint Proxy Statement, the term "AXENT" refers to
AXENT Technologies, Inc. and its subsidiaries.
 
 
                                       1

  Raptor. Raptor develops, markets, licenses and supports a family of
integrated network security software products that provide comprehensive,
enterprise-wide security for organizational networks, including networks that
are connected to the Internet. Raptor's application-level Eagle firewall and
EagleMobile virtual private network technology form the basis of a network
security solution that enables an organization to protect its network from
unauthorized access by internal and external users and to secure organizational
communications over the Internet and internal networks, including "intranets."
Raptor's integrated enterprise-wide network security solution consists of
individual product modules that secure organizational networks, including
networks connected to the Internet, LANs and Intranets, mobile PC users and
remote sites. Raptor's network security solutions are designed to enable
organizations to protect valuable data, extend the boundaries of organizational
networks without compromising network integrity and capitalize on the emergence
of the Internet as a medium of communications and commerce.
 
  Raptor's principal executive offices are located at 69 Hickory Drive,
Waltham, Massachusetts 02154, and its telephone number is (781) 487-7700. As
used in this Prospectus/Joint Proxy Statement, the term "Raptor" refers to
Raptor Systems, Inc. and its subsidiaries.
 
  The Combined Company. By combining the businesses of AXENT and Raptor, AXENT
will be positioned to address a broad range of security issues facing large
enterprises while providing centralized management and administration of
enterprise security solutions. The combined product offerings of Raptor and
AXENT will enable customers to simplify the enterprise security problem while
securing their corporate data more efficiently and effectively than before.
 
  AXENT believes that the combined products will enhance AXENT's position as a
leading source for enterprise security solutions. The Merger combines AXENT's
strength in multi-platform enterprise security management, intrusion detection,
remote access security, single sign-on and user administration with Raptor's
leading Virtual Private Network ("VPN"), Web and Intranet/Internet firewall
security technologies.
 
  The Merger will combine AXENT's large direct sales force and indirect channel
with Raptor's strong value added reseller ("VAR"), original equipment
manufacturer ("OEM") and distributor channels. In addition, the Merger will add
Raptor's experience and expertise in managing indirect channels to the combined
businesses of Raptor and AXENT.
 
  Additionally, the Merger will add Raptor's experienced development team to
the development teams in AXENT's business units responsible for security
management, resource management and authentication. It is expected that
Raptor's development team will continue to develop new information security
solutions and will work with AXENT's development staff to integrate Raptor's
products and technologies with those of AXENT.

  AXENT. Broadview Associates LLC ("Broadview") delivered its written opinion
to the AXENT Board to the effect that, as of November 30, 1997, and based upon
and subject to certain matters stated in its opinion, the consideration to be
paid by AXENT to the Raptor stockholders pursuant to the Merger is fair, from a
financial point of view, to AXENT and its stockholders. The full text of the
written opinion of Broadview, which sets
 
                                       3
<PAGE>
 
forth assumptions made, matters considered and limitations on the review
undertaken in connection with the opinion, is attached hereto as Annex B and is
incorporated herein by reference. HOLDERS OF AXENT COMMON STOCK ARE URGED TO,
AND SHOULD, READ SUCH OPINION IN ITS ENTIRETY. See "The Merger and the AXENT
Share Proposal--Opinion of AXENT's Financial Advisor."
 
  Raptor. NationsBanc Montgomery Securities, Inc. ("Montgomery") delivered its
written opinion, dated as of November 28, 1997, to the Raptor Board that, as of
such date and based upon and subject to certain matters stated in its opinion,
the Conversion Ratio (as defined below) is fair, from a financial point of
view, to Raptor's stockholders. The full text of the written opinion of
Montgomery, which sets forth assumptions made, matters considered and
limitations on the review undertaken in connection with the opinion, is
attached hereto as Annex C and is incorporated herein by reference. HOLDERS OF
RAPTOR COMMON STOCK ARE URGED TO, AND SHOULD, READ SUCH OPINION IN ITS
ENTIRETY. See "The Merger and the AXENT Share Proposal--Opinion of Raptor's
Financial Advisor."
 
THE MERGER
 
  Effects of the Merger. Upon consummation of the Merger, pursuant to the
Merger Agreement, (i) Merger Subsidiary will be merged with and into Raptor,
with Raptor being the surviving wholly-owned subsidiary of AXENT (the
"Surviving Corporation"), and (ii) each issued and outstanding share of Raptor
Common Stock (other than shares of Raptor Common Stock owned beneficially by
AXENT or the Merger Subsidiary) will be converted into the right to receive
such number of shares of AXENT Common Stock as is equal to the Conversion
Ratio. Raptor stockholders will receive cash in lieu of any fractional shares
of AXENT Common Stock to which such Raptor stockholders would otherwise have
been entitled. See "The Merger Agreement--The Merger."
 
  Conversion Ratio. Each share of Raptor Common Stock outstanding immediately
prior to the Effective Time (as defined below) will be converted into 0.80 of a
share of AXENT Common Stock (the "Conversion Ratio").
 
  Exchange of Options. Upon consummation of the Merger, each then outstanding
option to purchase Raptor Common Stock (a "Raptor Option") will be exchanged
for an option to purchase the number of shares of AXENT Common Stock (rounded
down to the next lowest whole number) equal to the number of shares of Raptor
Common Stock issuable upon exercise of such Raptor Option multiplied by the
Conversion Ratio (an "AXENT Option"). The exercise price per share (rounded up
to the next highest whole cent) of an AXENT Option will be equal to the
exercise price of such Raptor Option divided by the Conversion Ratio. See "The
Merger and the AXENT Share Proposal--Exchange Plan."
 
EFFECTIVE TIME OF THE MERGER
 
  The Merger will become effective upon the filing of a duly executed
Certificate of Merger with the Secretary of State of the State of Delaware (the
"Effective Time"). It is anticipated that the Merger will become effective as
promptly as practicable after the requisite stockholder approval has been
obtained and all regulatory approvals and other conditions to the Merger set
forth in the Merger Agreement have been satisfied or waived. It is anticipated
that, assuming all conditions are met, the Merger will occur on or about
February 5, 1998. See "The Merger Agreement--Conditions."
 
MANAGEMENT OF RAPTOR AFTER THE MERGER
 
  After the Effective Time, it is expected that the current directors and
officers of the Merger Subsidiary will continue as members of management of the
Surviving Corporation, which will operate as a wholly-owned subsidiary of
AXENT. As a result, none of Raptor's present directors or officers will
automatically continue as a
 
                                       4
<PAGE>
 
director or officer of the Surviving Corporation. It is anticipated that many
of Raptor's present officers will become officers and employees of AXENT or the
Surviving Corporation and three directors of the Raptor Board will become
directors of the AXENT Board. See "The Merger--Interests of Certain Persons in
the Merger."
 
CONDITIONS TO THE MERGER
 
  The respective obligations of AXENT and Raptor to consummate the Merger are
subject to the satisfaction of a number of conditions, including, among others,
(i) approval by the stockholders of AXENT and Raptor; (ii) approval for
quotation on Nasdaq of the AXENT Common Stock to be issued in the Merger; (iii)
effectiveness of the Registration Statement of which this Prospectus/Joint
Proxy Statement is a part; (iv) no temporary restraining order, preliminary or
permanent injunction preventing the Merger shall have been issued; (v) receipt
of all authorizations, consents, orders or approvals of, or declarations or
filings with, or expirations of waiting periods imposed by, any governmental
entity; (vi) receipt by each party of various legal opinions, accountants'
pooling and comfort letters and other certificates, consents and approvals from
the other parties to the Merger Agreement and from third parties; (vii)
accuracy in all material respects of the representations and warranties of each
party and compliance in all material respects with all covenants and conditions
by each party; and (viii) receipt of certain agreements from stockholders of
Raptor and AXENT, including Voting and Support Agreements and Affiliate's
Agreements; (ix) AXENT shall have fixed the number of directors on its board at
seven and duly appointed or elected Robert Steinkrauss, Shaun McConnon and
Robert Schechter to fill vacancies created by the resignations of three current
AXENT directors; and (x) AXENT shall have received the resignations of each
director of Raptor. See "The Merger and the AXENT Share Proposal--Accounting
Treatment," "The Merger and the AXENT Share Proposal--Certain Federal Income
Tax Consequences" and "The Merger Agreement--Conditions."
 
TERMINATION AND AMENDMENT
 
  The Merger Agreement may be terminated at any time prior to the Effective
Time, whether before or after approval of the matters presented in connection
with the Merger by the stockholders of Raptor or AXENT: (i) by mutual written
consent of AXENT and Raptor; (ii) by AXENT in the event Raptor has an uncured
breach or by Raptor in the event AXENT or the Merger Subsidiary has an uncured
breach of any material representation, warranty or covenant contained in the
Merger Agreement; (iii) by AXENT or Raptor, if, at the Raptor Special Meeting
or AXENT Special Meeting (including any adjournments or postponements thereof),
the requisite vote of the stockholders of Raptor or AXENT, respectively, in
favor of the Merger Agreement and the Merger shall not have been obtained; (iv)
by either AXENT or Raptor if the Merger shall not have been consummated by May
15, 1998; (v) by either AXENT or Raptor if a court of competent jurisdiction or
other governmental entity shall have issued a final order, decree or ruling, or
taken any other action, having the effect of permanently restraining, enjoining
or otherwise prohibiting the Merger; (vi) by AXENT if Raptor's Board of
Directors withdraws or modifies its recommendation of the Merger in a manner
adverse to AXENT or recommends or publicly announces an Acquisition Proposal
(as defined in the Merger Agreement) or a tender offer or exchange offer for
twenty percent or more of the outstanding shares of Raptor Common Stock shall
have been commenced and the Raptor Board of Directors has recommended that the
Raptor stockholders tender their shares or has publicly announced its intention
to take no position with respect to such tender offer; or (vii) by Raptor if
Raptor's Board of Directors makes a "Fiduciary Determination" (as defined
herein). See "The Merger Agreement--Termination."
 
  If (A) AXENT terminates the Merger Agreement for reasons described in clause
(vi), (B) Raptor terminates the Merger Agreement for reasons described in
clause (vii) or (C) either AXENT or Raptor terminate the Merger Agreement for
the reasons described in (iii) (as a result of Raptor's failure to obtain the
requisite vote of the Raptor stockholders) and at the time an Acquisition
Proposal involving Raptor shall have been announced or proposed and not
withdrawn or abandoned and Raptor shall have subsequently consummated such
Acquisition Proposal within 270 days of the termination of the Merger
Agreement, Raptor is required to pay a fee to AXENT equal to $8,850,316.
 
                                       5
<PAGE>
 
 
  The Merger Agreement may be amended by the written agreement of AXENT, Raptor
and the Merger Subsidiary at any time before or after the approval of AXENT's
or Raptor's stockholders; provided, however, that any amendment effected
subsequent to such approval shall be subject to the restrictions contained in
the Delaware General Corporation Law. See "The Merger Agreement--Amendment."
 
SURRENDER OF CERTIFICATES
 
  If the Merger becomes effective, AXENT will mail a letter of transmittal with
instructions to all holders of record of Raptor Common Stock at the Effective
Time for use in surrendering their stock certificates in exchange for
certificates representing shares of AXENT Common Stock and a cash payment in
lieu of fractional shares, if any. CERTIFICATES SHOULD NOT BE SURRENDERED UNTIL
THE LETTER OF TRANSMITTAL IS RECEIVED. See "The Merger Agreement--Conversion of
Securities."
 
APPRAISAL RIGHTS
 
  Under Delaware law, the holders of AXENT Common Stock and Raptor Common Stock
are not entitled to any appraisal rights in connection with the Merger. See
"The Merger and the AXENT Share Proposal--Appraisal Rights."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
  The Merger is intended to qualify as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code").
If the Merger so qualifies, no gain or loss would be recognized by AXENT,
Raptor or the Merger Subsidiary, and no gain or loss would be recognized by any
stockholders of Raptor, except in respect of cash received for fractional
shares. Neither AXENT nor Raptor has requested a ruling from the Internal
Revenue Service (the "IRS") in connection with the Merger. Nevertheless,
consummation of the Merger is conditioned upon there being delivered prior to
the Effective Time to each of AXENT and Raptor an opinion of its respective
counsel (the "Tax Opinions") to the effect that the Merger will constitute a
tax-free reorganization within the meaning of Section 368(a) of the Code. For a
further discussion of federal income tax consequences of the Merger, including
the possible effects of a successful challenge by the IRS to the qualification
of the Merger as such a reorganization, see "The Merger and the AXENT Share
Proposal--Certain Federal Income Tax Consequences."
 
ACCOUNTING TREATMENT
 
  The Merger is intended to qualify as a pooling-of-interests for accounting
and financial reporting purposes under generally accepted accounting principles
("GAAP"). In connection therewith, certain stockholders of AXENT and Raptor are
required to enter into Affiliate's Agreements whereby such stockholders agree
not to sell or otherwise dispose of any shares of AXENT Common Stock until
AXENT has publicly released statements of combined financial results covering
at least 30 days of operations after the Effective Time. See "The Merger and
the AXENT Share Proposal--Affiliate's Agreements."
 
LISTING
 
  It is a condition to the Merger that the shares of AXENT Common Stock to be
issued in the Merger be authorized for listing on Nasdaq, subject to official
notice of issuance.
 
RESTRICTIONS ON RESALE OF SECURITIES ISSUED IN THE MERGER
 
  Subject to the Affiliate's Agreements described above, shares of AXENT Common
Stock issued in the Merger will be freely transferable, except for shares
issued to persons who may be deemed "affiliates" of Raptor, which will be
subject to certain restrictions on resale under Rule 145 promulgated under the
Securities
 
                                       6
<PAGE>
 
Act. AXENT has agreed to file and keep effective for 270 days from the date
that AXENT has publicly released statements of combined financial results
covering at least 30 days of operations, a shelf registration statement on Form
S-3 covering the shares of AXENT Common Stock to be held by "affiliates" of
Raptor immediately following the Effective Time which will permit such
"affiliates" to sell their shares without regard to the requirements of Rule
145 in open-market or similar transactions. See "The Merger and the AXENT Share
Proposal--Federal Securities Law Consequences."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  In considering the recommendation of the Raptor Board with respect to the
Merger Agreement and the transactions contemplated thereby, Raptor stockholders
should be aware that certain members of Raptor's management and the Raptor
Board have certain interests in the Merger that are in addition to, or
different from, the interests of stockholders of Raptor generally. These
interests arise from, among other things, certain severance, consulting, bonus,
employee benefit plans, options, indemnification and insurance arrangements and
other matters which AXENT will assume or has agreed to provide after the
Merger. In addition, it is a condition to the Merger that subject to the
consummation of the Merger, the AXENT Board shall appoint Robert Steinkrauss
(Chairman of the Raptor Board), Shaun McConnon (President, Chief Executive
Officer and a director of Raptor) and Robert Schechter to the AXENT Board. See
"The Merger and the AXENT Share Proposal--Interests of Certain Persons in the
Merger."
 
VOTING AND SUPPORT AGREEMENTS
 
  Certain stockholders of AXENT and Raptor, who as of December 31, 1997, the
record date, held in the aggregate approximately  % and 20% of the outstanding
AXENT Common Stock and Raptor Common Stock, respectively, have entered into
Voting and Support Agreements providing, among other things, to vote such
shares in favor of the Merger and the Merger Agreement. See "The Merger and the
AXENT Share Proposal--Voting and Support Agreements."
 
COMPARISON OF STOCKHOLDER RIGHTS
 
  See "Comparison of Stockholders Rights" for a summary of the material
differences between the rights of holders of AXENT Common Stock and Raptor
Common Stock.
 
RISK FACTORS
 
  In considering the proposed Merger, stockholders should consider, among other
risks, the risks set forth under the caption "Risk Factors," including, but not
limited to:
 
  .  Challenges of integration of the AXENT and Raptor businesses.
 
  .  Potential dilution to stockholders if the Merger fails to produce the
     anticipated benefits or if the Merger has other adverse effects not
     currently anticipated.
 
  .  The Conversion Ratio was fixed at the time of execution of the Merger
     Agreement by the parties and is not subject to adjustment. Any increase
     or decrease in the market price of the shares of AXENT Common Stock will
     correspondingly increase or decrease the value of the Merger
     consideration to be received by the holders of Raptor Common Stock
     pursuant to the Merger. In particular, the stock prices for many
     companies in the technology and emerging growth sector have experienced
     wide fluctuations which have often been unrelated to the operating
     performance of such companies.
 
  .  Potential adverse effects on certain customers' purchasing decisions as
     a result of the Merger.
 
  .  Incurrence of unanticipated expenses, delays and inefficiencies relating
     to integration of the businesses and sales channels.
 
  .  Potential loss of key employees, consultants, distributors or resellers
     of Raptor.
 
  .  Increased competition from companies against whom AXENT and Raptor have
     not previously competed and potential adverse affects on collaborative,
     marketing and reselling arrangements.

RECENT DEVELOPMENTS
 
  On December 4, 1997, a lawsuit was filed purportedly on a class action basis
on behalf of the stockholders of Raptor against Raptor, the members of the
Raptor Board and AXENT. The complaint alleges that Raptor and the Raptor Board
breached their fiduciary duties in connection with the approval of the Merger.
The complaint seeks to enjoin the consummation of the Merger under the terms
presently proposed and also seeks unspecified damages. Raptor and AXENT believe
that the allegations in the complaint are without merit and will defend the
action vigorously. See "Litigation."

  The selected pro forma combined financial information of AXENT and Raptor is
derived from the unaudited pro forma condensed combined financial statements
and should be read in conjunction with such pro forma statements and notes
thereto included elsewhere in this Prospectus/Joint Proxy Statement. The
unaudited pro forma combined selected financial data for AXENT and Raptor give
effect to the Merger as though it occurred on January 1, 1994 for statement of
operations and other data purposes and September 30, 1997 for balance sheet
data purposes, using the pooling-of-interests method of accounting. The pro
forma financial information does not purport to represent what AXENT's
financial position or results of operations would have actually been had the
Merger occurred at the beginning of the earliest period presented or to project
AXENT's financial position or results of operations for any future date or
period. In addition, it does not incorporate any benefits from anticipated cost
savings or synergies of operations of the combined companies. Estimated direct
costs of the Merger and other costs of consolidation have not been determined
and are not included in pro forma combined net income (loss) per share for the
periods presented.

               COMPARATIVE HISTORICAL AND COMBINED PER SHARE DATA
 
  The following tables set forth certain share data for AXENT and Raptor on
both a historical and pro forma combined basis after giving effect to the
Merger as a pooling-of-interests as though it occurred on January 1, 1994. The
equivalent pro forma loss per share and stockholders' equity (deficit) is based
upon a Conversion Ratio of 0.80 provided by the Merger Agreement as discussed
in the footnotes below. The comparative historical and combined per share data
are not necessarily indicative of the results that actually would have occurred
if the Merger had been completed on January 1, 1994 or which may be expected in
the future. The combined financial information should be read in conjunction
with the historical consolidated financial statements of AXENT and Raptor
incorporated by reference herein and in conjunction with the Unaudited Pro
Forma Combined Condensed Financial Statements of AXENT and Raptor included
elsewhere herein. Neither AXENT nor Raptor has ever paid cash dividends. It is
anticipated that AXENT will retain all earnings, when attained, for use in the
expansion of its business and therefore it does not anticipate paying any cash
dividends in the foreseeable future. Estimated direct costs of the Merger and
other costs of consolidation have not been determined and are not included in
pro forma combined net income (loss) per share for the periods presented.

                                 RISK FACTORS
 
  This Prospectus/Joint Proxy Statement contains certain forward-looking
statements within the meaning of Section 27A of the Securities Act and Section
21E of the Exchange Act. For this purpose, any statements contained herein
that are not statements of historical fact may be deemed to be forward-looking
statements. Without limiting the foregoing, the words "believes,"
"anticipates," "plans," "expects" and similar expressions are intended to
identify forward-looking statements. Actual results could differ materially
from those indicated by such forward-looking statements as a result of certain
risk factors set forth below and elsewhere in this Prospectus/Joint Proxy
Statement.
 
  IN ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS/JOINT
PROXY STATEMENT, AXENT AND RAPTOR STOCKHOLDERS SHOULD CAREFULLY CONSIDER THE
FOLLOWING RISKS RELATING TO THE MERGER.
 
RISKS RELATING TO THE MERGER
 
  CHALLENGES OF INTEGRATION. The respective management teams of AXENT and
Raptor have entered into the Merger Agreement with the expectation that the
Merger will result in beneficial synergies. See "The Merger and the AXENT
Share Proposal--Reasons for the Merger." Achieving the anticipated benefits of
the Merger will depend in part upon whether the integration of the two
companies' businesses is accomplished in an efficient and effective manner,
and there can be no assurance that this will occur. The successful combination
of companies in a rapidly changing high technology industry may be more
difficult to accomplish than in other industries. The combination of the two
companies will require, among other things, integration of the companies'
respective product offerings and coordination of their sales and marketing and
research and development efforts. There can be no assurance that such
integration will be accomplished smoothly or successfully. The difficulties of
such integration may be increased by the necessity of coordinating
geographically separated organizations and addressing possible differences in
corporate cultures and management philosophies. The integration of certain
operations following the Merger will require the dedication of management
resources which may temporarily distract attention from the day-to-day
business of the combined companies. The business of the combined companies may
also be disrupted by employee uncertainty and lack of focus during such
integration. The inability of management to successfully integrate the
operations of the two companies could have a material adverse effect on the
business, results of operations and financial condition of AXENT.
 
  POSSIBLE DILUTION. Although the companies believe that beneficial synergies
will result from the Merger, there can be no assurance that the combining of
the two companies' businesses, even if achieved in an efficient and effective
manner, will result in increased earnings per AXENT share (taking into
consideration the greater number of AXENT shares outstanding as a result of
the Merger) or a financial condition superior to that which would have been
achieved by AXENT on a stand alone basis. While neither AXENT nor Raptor
anticipates that the Merger will be dilutive to the stockholders of the
respective companies, there can be no assurance that, if the Merger fails to
produce the anticipated benefits, it will not have the dilutive effect of
causing the per share earnings of the combined company to be lower than they
would have been for either company if operated independently. Furthermore, if
the anticipated benefits are not achieved, or if the Merger has other adverse
effects that are not currently anticipated, the Merger could result in a
reduction in per share earnings of the combined company (as compared to the
per share earnings that either or both of the companies would have achieved if
the Merger had not occurred). Even if the effects of the Merger prove to be as
anticipated, there can be no assurance that future earnings will not be
adversely affected by any number of economic, market or other factors that are
not related to the Merger.
 
  POSSIBLE ADVERSE EFFECT ON CUSTOMER PURCHASING DECISIONS. There can be no
assurance that present and potential customers of AXENT and Raptor will
continue their current buying patterns without regard to the announced Merger.
In particular, AXENT and Raptor believe that certain customers' purchasing
decisions may be affected as they evaluate the future product strategy and
competitive positioning of AXENT, Raptor and the combined company. Any adverse
decisions made as a result of such evaluations could have a material adverse
 
                                      15
<PAGE>
 
effect upon the future results of operations of AXENT and/or Raptor and/or the
combined company both in the near and the long term.
 
  INCURRENCE OF UNANTICIPATED EXPENSES, DELAYS AND INEFFICIENCIES. AXENT
expects to incur a one-time charge in connection with the Merger, including
estimated direct costs of consolidation (such as professional fees, filing
fees, printing, distribution and solicitation costs, expenses incurred in
eliminating duplicative products and severance, consulting and bonus costs)
and other costs in the first quarter of 1998, the quarter in which the Merger
is expected to be consummated. The one-time charge could aggregate up to
approximately l0% of the aggregate consideration paid in the Merger. In
addition, unanticipated expenses, delays and inefficiencies may be incurred
relating to the integration of the businesses of Raptor and AXENT, including
the integration of marketing, distribution and administrative functions,
product development and support functions and indirect sales channels.
Although AXENT expects that the elimination of duplicative expenses as well as
other efficiencies related to the integration of the business of Raptor may
offset additional expenses over time, there can be no assurance that such net
benefit will be achieved in the near term, or at all. See "Unaudited Pro Forma
Condensed Combined Financial Data Statements of AXENT and Raptor."
 
  LOSS OF KEY EMPLOYEES, CONSULTANTS, DISTRIBUTORS OR RESELLERS OF RAPTOR. As
part of its strategy, Raptor has established a number of strategic
relationships with consultants, systems integrators, resellers and
distributors. These companies provide software development, reselling and
training services that are important to existing and future business. These
relationships are typically nonexclusive and, in some cases, may be
discontinued at any time. The successful continuation of Raptor's business by
AXENT and the successful integration of the companies' operations depends upon
the continued contribution of key employees of Raptor, the continuation of
Raptor's rights under various agreements and the continued loyalty of key
distributors and resellers of Raptor's products. The loss of key personnel,
distributors or resellers of Raptor could adversely affect the financial
condition and results of operation of Raptor before completion of the Merger
and of the combined companies after completion of the Merger. The termination
by third parties of contractual rights of Raptor existing at the time of
execution of the Merger Agreement could adversely affect the financial
condition and results of operations of the combined companies after completion
of the Merger. Competition for qualified personnel, distributors and resellers
is intense, and there can be no assurance that AXENT will be successful in
retaining Raptor's key employees, consultants, distributors and resellers. In
addition, during the pre-merger and integration phases, aggressive competitors
may undertake initiatives to attract customers and to recruit key employees,
consultants, distributors and resellers of Raptor.
 
  SHARE PRICE FLUCTUATION THROUGH THE EFFECTIVE TIME. The relative market
prices of shares of Raptor Common Stock and shares of AXENT Common Stock at
the Effective Time may vary significantly from the prices as of the date of
execution of the Merger Agreement, the date hereof or the date on which the
respective Raptor and AXENT Special Meetings occur, due to changes in the
business, operations and prospects of Raptor or AXENT, market assessments of
the Merger, the synergies expected to be achieved in the Merger, the
likelihood that the Merger will be consummated and the timing thereof, general
market and economic conditions, and other factors such as market perception of
shares of network security software products generally.
 
  The Conversion Ratio was fixed at 0.80 at the time of execution of the
Merger Agreement by the parties and is not subject to adjustment. Any increase
or decrease of the market price of the shares of AXENT Common Stock will
correspondingly increase or decrease the value of the merger consideration to
be received by the holders of Raptor Common Stock pursuant to the Merger. In
considering whether to approve the Merger and the Merger Agreement, the
holders of Raptor Common Stock and the holders of AXENT Common Stock should
consider the risks associated with a potential change in the price of AXENT
Common Stock between the date of this Prospectus/Joint Proxy Statement and the
Effective Time. The closing price of AXENT's Common Stock was $20.75 on
November 28, 1997 (the last trading day prior to the date that the Merger was
publicly announced) and was $15.75 on December 22, 1997.
 
  INCREASED COMPETITION; POSSIBLE ADVERSE EFFECTS ON CORPORATE
RELATIONSHIPS. As a result of the Merger and increasing consolidation in the
information security industry, AXENT will become subject to
 
                                      16
<PAGE>
 
increased competition, including competition against companies with which
AXENT and Raptor, individually, have not previously competed. The Merger also
may have possible adverse effects on existing collaborative, marketing and
reselling agreements to which AXENT and Raptor are parties, as well as
expected or anticipated collaborative, marketing or distribution arrangements
or relationships.
 
  FEDERAL INCOME TAX CONSEQUENCES AND CONTINUITY OF INTEREST. One of the
requirements for the Merger to be treated as a "reorganization" that is tax-
free under the Code is that the "continuity of interest" requirement be met.
Under this requirement, holders of Raptor Common Stock must intend, at the
time of the Merger, to retain a portion of their AXENT Common Stock, such that
Raptor stockholders, as a group, have a significant equity interest in AXENT
after the Merger. If former Raptor stockholders should collectively sell in
excess of 50% of the AXENT Common Stock to be delivered at the Effective Time
within a relatively short period after the Effective Time, for example one to
two years, the IRS may contend that this requirement is not met. In such
event, the Merger may be determined to be a taxable transaction and former
Raptor stockholders would recognize taxable income as of the date of the
Merger based on the difference between the tax basis in their shares of Raptor
Common Stock and the fair market value of AXENT Common Stock received by them
on that date (even if such fair market value declines after the Merger).
Consummation of the Merger is conditioned upon there being delivered prior to
the Effective Time to each of AXENT and Raptor an opinion of its respective
counsel to the effect that the Merger will constitute a reorganization under
Section 368(a) of the Code. See "The Merger--Certain Federal Income Tax
Consequences."
 
  ADDITIONAL SHARES TO BE ISSUED BY AXENT, SHARES ELIGIBLE FOR FUTURE
SALE. Based on the 15,930,162 shares of Raptor Common Stock outstanding as of
the Raptor Record Date and assuming all outstanding options are exercised,
AXENT would issue 12,744,130 shares of AXENT Common Stock in the Merger. On
the Raptor Record Date there were     shares outstanding and outstanding
options to acquire     shares of Raptor Common Stock. In general, the shares
issued for outstanding shares of Raptor Common Stock will be freely tradable
upon the issuance of certain financial information regarding the combined
companies following the Merger. At the time of the Merger, substantially all
shares of outstanding AXENT Common Stock will be eligible for sale in the
public market subject in certain cases to volume and other limitations. An
additional 2,762,897 shares subject to outstanding options and shares reserved
for issuance under AXENT's stock option plans have been registered for sale
with the Commission. The sale of any of the foregoing shares may cause
substantial fluctuations in the price of AXENT Common Stock over short periods
of time. Moreover, sales of substantial amounts of AXENT Common Stock
(including shares issued upon the exercise of outstanding options) in the
public market could materially adversely affect the market price of the AXENT
Common Stock, thereby making it more difficult for AXENT to sell equity
securities or equity-related securities in the future at a time and price that
AXENT deems advantageous.
 
RISKS RELATING TO AXENT AND RAPTOR
 
  In addition to the foregoing risks, the risks set forth below relating to
AXENT and to Raptor will be applicable to the Merger Subsidiary.
 
RISKS RELATING TO AXENT
 
  HISTORICAL LOSSES FROM CONTINUING OPERATIONS. AXENT incurred losses from
continuing operations for the years 1992, 1994 and 1995 of $359,000,
$3,273,000 and $2,695,000, respectively. AXENT had income from continuing
operations for the years 1993 and 1996 and the nine months ended September 30,
1997 of $569,000, $3,285,000 and $3,721,000 (excluding a one-time charge of
approximately $27,632,000 relating to its acquisition of AssureNet),
respectively. A substantial portion of AXENT's funding in 1994 through 1996
was derived from its discontinued operations, which contributed income of
$3,782,000, $5,050,000, and $2,395,000, respectively. While developing and
enhancing the OmniGuard family of software products, AXENT pursued a
divestment strategy with regard to its utility, storage and Helpdesk software
products, which constitute the discontinued operations. AXENT began marketing
the first of its OmniGuard products in November 1994. Due to AXENT's limited
operating history with respect to the OmniGuard products, no assurance can be
given regarding its future
 
                                      17
<PAGE>
 
performance. In particular, no assurance can be given that AXENT's information
security business will be capable of sustaining profitability on a quarterly
or annual basis or that the growth that AXENT has experienced will be
sustainable. Although AXENT has experienced significant growth in recent
periods, such growth may not be sustainable and should not be considered
indicative of future growth of its business, revenues or profits.
 
  DEPENDENCE ON OMNIGUARD FAMILY OF PRODUCTS; NEW PRODUCT INTRODUCTIONS. The
first OmniGuard product, Enterprise Security Manager, was released
commercially in November 1994; Intruder Alert was released commercially in
April 1995; Enterprise Access Control for UNIX was released commercially in
April 1995; Enterprise Access Control for PCs was released commercially in May
1995; Enterprise Access Control for Windows 95 and UNIX Privilege Manager were
released commercially in October 1996; and Enterprise Resource Manager was
released commercially in December 1996. In addition, the Defender
authentication products have only been distributed by AXENT since its
acquisition of AssureNet in January 1997. Accordingly, AXENT has a relatively
short operating history with these products. AXENT's future success will in
large part depend on revenues from these products. AXENT is currently devoting
significant resources to the development of versions of its products that
operate on other hardware platforms and operating systems, the development of
enhancements to its products and the development of additional products that
will be offered as part of the OmniGuard family of software products. There
can be no assurance that AXENT will successfully complete the development of
these products in a timely fashion, that AXENT will be able to develop
versions of its OmniGuard products that operate on the range of hardware
platforms and operating systems currently anticipated or that AXENT's current
or future products will satisfy the needs of the computer information security
market or achieve market acceptance or, if market acceptance is achieved, that
AXENT will be able to maintain such acceptance for a significant period of
time and maintain continued compatibility with new releases of operating
systems and with new operating systems that may be developed. In addition,
with respect to Enterprise Resource Manager, there can be no assurance that
installation and consulting services required by prospective customers will be
available or that the externally supplied directory service utilized by ERM
will be widely used and accepted. Any inability of AXENT to develop on a
timely basis products that address changing customer requirements may require
AXENT to substantially increase development expenditures or may result in a
loss of market share to a competitor. There can also be no assurance that
security-related products or technologies developed by others will not
adversely affect AXENT's competitive position or render its products or
technologies noncompetitive or obsolete.
 
  POTENTIAL SIGNIFICANT FLUCTUATIONS IN QUARTERLY OPERATING RESULTS AND
LENGTHY SALES CYCLE. AXENT has experienced significant quarterly fluctuations
in its operating results and anticipates such fluctuations in the future.
Generally, revenues, operating income and net income for AXENT's fourth
quarter are higher than those for the first quarter of the following year. In
addition, revenues tend to be lower in the summer months, particularly in
Europe, when businesses often defer purchase decisions. AXENT has historically
recognized a substantial portion of its license revenues in the last month of
each quarter. In its direct sales of software licenses, AXENT generally ships
its software products on a trial basis and recognizes revenue upon receipt of
a binding obligation by the customer and, as a result, has little or no
backlog. Quarterly revenues and operating results therefore depend on the
volume and timing of orders received during the quarter, which are difficult
to forecast. In addition, consulting service revenues tend to fluctuate as
projects, which may continue over several quarters, are undertaken or
completed. Operating results may also fluctuate on a quarterly basis due to
factors such as the demand for AXENT's products, the introduction of new
products and product enhancements by AXENT or its competitors, market
acceptance of new products introduced by AXENT or its competitors and the
size, timing, cancellation or delay of customer orders, including cancellation
or delay of such orders in anticipation of new product introduction or
enhancement. AXENT's quarterly operating results are also affected by the
budgeting cycles of customers, changes in the proportion of revenues
attributable to licenses and service fees, changes in the mix of products
sold, changes in the percentage of products sold through AXENT's direct sales
force and its indirect distribution channels, changes in product pricing,
changes in the development of AXENT's direct and indirect distribution
channels, competitive conditions in the industry and changes in general
economic conditions.
 
  The value of individual transactions as a percentage of quarterly revenues
can be substantial, and particular transactions may generate a substantial
portion of the operating profits for the quarter in which they are signed. The
sales of AXENT's security products generally involve significant testing by
and education of prospective customers as well as a commitment of resources by
both parties. For these and other reasons, the sales cycle
 
                                      18
<PAGE>
 
associated with the sales of AXENT's OmniGuard products is typically between
nine and 12 months and subject to a number of significant risks over which
AXENT has little or no control. Because AXENT's staffing and other operating
expenses are based on anticipated revenue levels, a substantial portion of
which is not typically generated until the end of each quarter, and a high
percentage of AXENT's expenses are fixed, delays in the receipt of orders can
cause significant variations in operating results from quarter to quarter. In
addition, AXENT may expend significant resources pursuing potential sales that
will not be consummated. AXENT also may choose to reduce prices or to increase
spending in response to competition or to pursue new market opportunities,
which may adversely affect AXENT's operating results. Accordingly, AXENT
believes that period-to-period comparisons of its results of operations may
not be meaningful and should not be relied upon as an indication of future
performance. Furthermore, there can be no assurance that AXENT will be able to
grow and sustain profitability on a quarterly basis.
 
  Due to all the foregoing factors, it is likely that in some future quarters
AXENT's operating results will be below the expectations of public market
analysts and investors. Regardless of the general outlook for AXENT's
business, the announcement of quarterly operating results below analyst and
investor expectations could have a material adverse effect on the price of
AXENT's Common Stock.
 
  RISKS ASSOCIATED WITH INFORMATION SECURITY MARKET. The market for AXENT's
OmniGuard software products is in an early stage of development. Declines in
demand for AXENT's products, whether as a result of competition, technological
change, the public's perception of the need for security products,
developments in the hardware and software environments in which these products
operate, general economic conditions or other factors, could have a material
adverse effect on AXENT's financial condition or results of operations. In
addition, an actual or perceived breach of network or computer security at one
of AXENT's customers, regardless of whether such breach is attributable to
AXENT's products, could adversely affect the market's perception of AXENT and
AXENT's financial condition or results of operations.
 
  PRODUCT DEVELOPMENT RISKS IN A RAPIDLY CHANGING INDUSTRY. The information
security industry is characterized by rapid changes, including frequent new
product introductions, continuing advances in technology and changes in
customer requirements and preferences. The introduction of new technologies
could render AXENT's existing products obsolete or unmarketable or require
AXENT to invest resources in products that may not become profitable. The
development cycle for AXENT's new products may be significantly longer than
AXENT's historical product development cycle, resulting in higher development
costs or a loss in market share. There can be no assurance that (i) AXENT will
be able to counter challenges to its current products; (ii) AXENT's future
product offerings will keep pace with the technological changes implemented by
competitors or persons seeking to breach information security; (iii) AXENT's
products will satisfy evolving preferences of customers and prospects; or (iv)
AXENT will be successful in developing and marketing products for any future
technology. Failure to develop and introduce new products and product
enhancements in a timely fashion could have a material adverse effect on
AXENT's financial condition and results of operations. Because of the
complexity of AXENT's software products which operate on or utilize multiple
platforms and communications protocols, AXENT has from time to time
experienced delays in introducing new products and product enhancements
primarily due to development difficulties or shortages of development
personnel. There can be no assurance that AXENT will not experience longer
delays or other difficulties that could delay or prevent the successful
development, introduction or marketing of new products or product
enhancements.
 
  INTENSE AND CONSTANTLY EVOLVING COMPETITION. Competition in the information
security market is intense and constantly evolving, and AXENT expects such
competition to increase in the future. AXENT believes that significant
competitive factors affecting this market are depth of product functionality,
breadth of platform support, product quality and performance, conformance to
industry standards, product price and customer support. In addition, the
ability to rapidly develop and implement new products and features for the
market is critical. There can be no assurance that AXENT can maintain or
enhance its competitive position against current and future competitors.
Significant factors such as the emergence of new products, fundamental changes
in computing technology and aggressive pricing and marketing strategies may
also affect AXENT's competitive position. Many of these factors are out of
AXENT's control.
 
                                      19
<PAGE>
 
  AXENT's competitors fall into four main categories: large, multi-product
vendors, single purpose product providers, platform vendors and publicly
available software.
 
  Large, multi-product vendors. AXENT's principal competitors include IBM,
Computer Associates International, Inc. ("Computer Associates"), Security
Dynamics Technologies, Inc. ("Security Dynamics"), Secure Computing
Corporation, Platinum Technology, Inc., Digital Equipment Corporation
("Digital") and Compagnie des Machines Bull SA ("Groupe Bull"). Each of these
organizations has strategic software products that cover various aspects of
information security and compete directly with one or more components of
AXENT's product line.
 
  Single purpose product providers. AXENT's principal single purpose product
competitors include Uti Maco GmbH, Memco Software Ltd, (Memco's products are
also marketed by Platinum Technology, Inc. and IBM's Tivoli business unit),
Fischer International Systems, Inc., Intrusion Detection, Inc., the Wheel
Group, Internet Security Systems, Inc., CheckPoint Software Technology, Ltd.
and Trusted Information Systems Inc. These vendors each sell products that
offer particular information security functions for specific computing
platforms. These products compete with one or more of AXENT's products in
specific functional areas or on specific platforms. There can be no assurance
that these competitors will not expand their product offerings to other
functional areas or platforms and compete with more of AXENT's products.
 
  Platform vendors. AXENT competes with platform vendors such as Cisco
Systems, Inc., Digital, Hewlett-Packard, IBM, Sun Microsystems, Inc. ("Sun")
and Microsoft Corp. ("Microsoft"). Each of these vendors offers operating
system software that often includes native security functionality. To the
extent that the security features which become incorporated in operating
systems overlap all or a portion of the functionality offered by AXENT's
products, AXENT's products may no longer be required by customers to meet
their information security requirements. All of these vendors have indicated
plans to expand the information security within their operating systems.
 
  Publicly available software. A substantial portion of AXENT's current
business comes from customers buying UNIX versions of its products. Certain
UNIX products that compete with one or more aspects of AXENT's products are
available in the public domain for little or no cost or from open systems
standards organizations such as the Open Software Foundation's ("OSF")
Distributed Computing Environment ("DCE"). OSF DCE technologies can be
licensed for a fee and have been incorporated into operating systems and into
third party security products.
 
  Many of AXENT's current and potential competitors have longer operating
histories, significantly greater financial, technical and marketing resources,
greater name recognition and a larger installed customer base than AXENT. In
addition, one or more of these competitors may be able to respond more quickly
to new or emerging technologies and changes in customer requirements, and to
devote greater resources to the development, promotion and sale of their
products than AXENT. There can be no assurance that AXENT's current or
potential competitors will not develop products comparable or superior to
those developed by AXENT or adapt more quickly than AXENT to new technologies,
evolving industry trends or changing customer requirements. Increased
competition could result in price reductions, reduced margins or loss of
market share, any of which could materially adversely affect AXENT's financial
condition or results of operations. There can be no assurance that AXENT will
be able to compete successfully against current and future competitors, or
that competitive pressures faced by AXENT will not have a material adverse
effect on its financial condition and results of operations. If AXENT is
unable to compete successfully against current and future competitors, AXENT's
financial condition and results of operations will be materially adversely
affected.
 
  MANAGEMENT OF CHANGE. AXENT has experienced changes in its operations that
have placed significant demands on AXENT's administrative, operational,
technical and financial resources. To compete effectively, both in its
domestic and international operations, and to manage future growth, if any,
AXENT must continue to strengthen its operational, financial and management
information reporting systems, controls and procedures on a timely basis and
expand, train and manage its work force. There can be no assurance that AXENT
will be able
 
                                      20
<PAGE>
 
to take such actions successfully. The failure of AXENT's management team to
effectively manage change could have a material adverse impact on AXENT's
financial condition and results of operations.
 
  RISKS ASSOCIATED WITH POSSIBLE ACQUISITIONS. In the normal course of its
business, AXENT evaluates potential acquisitions of businesses, products and
technologies, such as Raptor, that could complement or expand AXENT's
business. In the event AXENT identifies an appropriate acquisition candidate,
there is no assurance that AXENT would be able to successfully negotiate the
terms of any such acquisition, finance such acquisition and integrate such
acquired business, products or technologies into AXENT's existing business and
operations. Furthermore, the negotiation of potential acquisitions as well as
the integration of an acquired business could cause diversions of management
time and resources. There can be no assurance that a given acquisition,
whether or not consummated, would not materially adversely affect AXENT's
financial condition and results of operations. If AXENT proceeds with one or
more additional significant acquisitions in which the consideration consists
of cash, a substantial portion of AXENT's available cash could be used to
consummate the acquisitions. If AXENT consummates one or more additional
significant acquisitions in which the consideration consists of stock,
stockholders of AXENT, including the former Raptor stockholders, could suffer
a significant dilution of their interests in AXENT. If AXENT consummates one
or more significant acquisitions accounted for as a purchase, substantial one-
time charges for write-offs associated with the acquisition may be incurred,
which could impair AXENT's financial position.
 
  RISK OF LIABILITY DUE TO ERRORS OR FAILURES OF PRODUCT SECURITY
FEATURES. Products as complex as those offered by AXENT may contain undetected
errors, failures or bugs when first introduced or when new versions are
released. AXENT has in the past discovered software errors, failures and bugs
in certain of its product offerings after their introduction and has
experienced delays or lost revenues during the period required to correct
these errors. In particular, the computer environment is characterized by a
wide variety of standard and non-standard configurations that make pre-release
testing for programming or compatibility errors very difficult and time-
consuming. Furthermore, there can be no assurance that, despite testing by
AXENT and by others, errors, failures or bugs will not be found in new
products or releases after commencement of commercial shipments by AXENT.
Errors, failures or bugs in AXENT's products could result in adverse
publicity, in product returns, in loss of or delay in market acceptance of
AXENT's products or in claims by the customer or others against AXENT although
AXENT has not experienced any material losses or claims by customers with
respect to errors, failures or bugs in its products. Alleviating such problems
could require significant expenditures of capital and resources by AXENT and
could cause interruptions, delays or cessation of service to AXENT's
customers. AXENT attempts to limit its liability to customers, including
liability arising from a failure of the security features contained in AXENT's
products, through contractual limitations of warranties and remedies. AXENT's
consulting agreements with its customers generally contain provisions designed
to limit AXENT's exposure to claims related to negligence or errors or
omissions by AXENT's employees and agents. However, some courts have held
similar contractual limitations of liability, or the "shrinkwrap licenses" in
which they sometimes are embodied, to be unenforceable. Accordingly, there can
be no assurance that such limitations will be enforced. AXENT also has
insurance providing coverage up to $2,000,000 annually and per occurrence with
respect to claims arising from product failure and related loss or damage to
data. Notwithstanding that insurance coverage, the consequences of errors,
failures or bugs in AXENT's products could have a material adverse effect on
AXENT's financial condition and results of operations.
 
  SALES AND DISTRIBUTION RISKS. As of November 30, 1997, AXENT had 91
employees in its sales organization and six employees in its marketing
organization, many of whom have been employed by AXENT for less than two
years. In order to support sales growth, if any, AXENT will need to maintain
the size of its sales and marketing staff, increase the staff's productivity
and expand its indirect distribution channels. There can be no assurance that
AXENT will be able to leverage successfully its sales force or that AXENT's
sales and marketing organization will successfully compete against the more
extensive and well funded sales and marketing organizations of many of AXENT's
current and future competitors. AXENT is continuing to develop its indirect
distribution channels in North America and Europe. There can be no assurance
that AXENT will be able to attract and retain third parties that will be able
to market AXENT's products effectively and will be
 
                                      21
<PAGE>
 
qualified to provide timely and cost-effective customer support and service.
AXENT's arrangements with its distributors and resellers generally do not
contain minimum purchase requirements, and such distributors and resellers may
carry competing product offerings. There can be no assurance that any
distributor or reseller will continue to represent AXENT's products.
 
  The inability to recruit, or the loss of, important sales personnel,
distributors or resellers could materially adversely affect AXENT's financial
condition and results of operations.
 
  DEPENDENCE ON KEY PERSONNEL. AXENT's success depends to a significant degree
upon the continuing contributions of its key management, sales, marketing,
professional services, customer support and product development personnel. The
loss of the services of any key employee could adversely affect AXENT's
financial condition and results of operations. AXENT believes that its future
success will depend in large part upon its ability to attract and retain
highly-skilled managerial, sales, marketing, professional services, customer
support and product development personnel. AXENT's operations require
consulting services personnel and sales consultants who are highly technically
trained in the field of information security, and the competition for such
individuals is intense. AXENT has at times experienced, and continues to
experience, difficulty in recruiting qualified personnel. Competition for
qualified personnel in the software industry is intense, and there can be no
assurance that AXENT will be successful in retaining its key employees or that
it can attract or retain additional skilled personnel as required.
 
  DEPENDENCE ON EXTERNAL DEVELOPMENT RESOURCES AND SUPPLIERS. AXENT relies and
will continue to rely on external resources for the development and production
of certain of its products and components thereof. AXENT's success will depend
in part on its continued ability to obtain and expand as needed product
development agreements with independent software developers and production
arrangements with suppliers. There can be no assurance that AXENT will be able
to obtain or expand product development agreements or production arrangements,
as needed, on favorable terms or at all or that independent developers will
complete products for AXENT on a timely basis, within acceptable guidelines or
at all.
 
 
  RISKS ASSOCIATED WITH INTERNATIONAL SALES. Sales outside North America
accounted for approximately 24% and 20% of AXENT's net revenues from its
information security products in the year ended December 31, 1996 and the nine
months ended September 30, 1997, respectively. Management expects that
international sales will continue to generate a significant portion of AXENT's
total revenue. AXENT's international business may be subject to a variety of
risks, including costs and risks relating to the establishment and expansion
of indirect distribution channels in certain countries or regions, delays in
expanding its international distribution channels, difficulties in collecting
international accounts receivable from distributors or resellers, and
increased costs associated with maintaining international marketing efforts.
AXENT's international sales are denominated in the local currency of the
country in which the sale was made, and AXENT is subject to the risks
associated with fluctuations in currency exchange rates. As AXENT does not
currently hedge foreign currency risk, a decrease in the value of any of these
foreign currencies relative to the U.S. dollar will affect the profitability
in U.S. dollars of AXENT's products sold in these markets. In addition, AXENT
is subject to the usual risks of doing business abroad, including increases in
duty rates, the introduction of non-tariff barriers and difficulties in
enforcement of intellectual property rights. There can be no assurance that
these factors will not have a material adverse effect on AXENT's financial
condition or results of operations.
 
  EFFECT OF GOVERNMENT REGULATION OF TECHNOLOGY EXPORTS. AXENT's international
sales and operations may be subject to risks such as the imposition of
governmental controls, new or changed export license requirements,
restrictions on the export of critical technology, trade restrictions and
changes in tariffs. While AXENT believes its products are designed to meet the
regulatory standards of foreign markets, any inability to obtain foreign
regulatory approvals on a timely basis could have a material adverse effect on
AXENT's financial condition or results of operations. Certain of AXENT's
products are subject to export controls under U.S. law, and AXENT believes it
has obtained all necessary export approvals when required. There can be no
assurance, however, that the list of products and countries for which export
approval is required, and the regulatory policies
 
                                      22
<PAGE>
 
with respect thereto, will not be revised from time to time. The inability of
AXENT to obtain required approvals under these regulations could materially
adversely affect the ability of AXENT to make international sales. For
example, because of U.S. governmental controls on the exportation of
encryption technology, AXENT has been unable to export some of its products
with the most robust information security encryption technology and will be
required to provide for recovery of encryption keys for access by governmental
authorities in order to export products containing certain Digital Encryption
Standard (DES) encryption algorithms. As a result, foreign competitors facing
less stringent controls on their products may be able to compete more
effectively than AXENT in the global information security market. There can be
no assurance that these factors will not have a material adverse effect on
AXENT's financial condition or results of operations.
 
  LIMITED PROTECTION OF INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS. AXENT
regards its software as proprietary, and its success and ability to compete is
dependent in part upon its proprietary technology and rights. AXENT relies on
copyright and trade secret laws, trademarks, confidentiality procedures and
contractual provisions to protect its proprietary software, documentation and
other proprietary information. Although AXENT holds two patents and has two
pending patent applications which cover certain aspects of its technology,
such patents and patent applications are unrelated to its information security
products. AXENT does not rely upon patent protection and there can be no
assurance that AXENT will seek patents on aspects of its technology relating
to its information security products, that any such patents will issue or that
any such patents will be sufficiently broad to protect AXENT's technology
relating to its information security products. Although the effectiveness of
AXENT's products is not dependent upon the secrecy of its proprietary
technology or licensed technology, the public disclosure of its technology
could result in a perception of breached security and reduced effectiveness of
AXENT's products, which could have an adverse effect on AXENT's financial
condition or results of operations. There also can be no assurance that the
confidentiality agreements and other methods on which AXENT relies to protect
its trade secrets and proprietary information and rights will be adequate.
Litigation to defend and enforce AXENT's intellectual property rights could
result in substantial costs and diversion of resources and could have a
material adverse effect on AXENT's financial condition and results of
operations regardless of the final outcome of such litigation. Despite AXENT's
efforts to safeguard and maintain its proprietary rights, there can be no
assurance that AXENT will be successful in doing so or that the steps taken by
AXENT in this regard will be adequate to deter misappropriation or independent
third-party development of its technology or to prevent an unauthorized third
party from copying or otherwise obtaining and using AXENT's products,
technology or other information that AXENT regards as proprietary. There can
also be no assurance that AXENT's trade secrets or non-disclosure agreements
will provide meaningful protection of AXENT's proprietary information.
Furthermore, there can be no assurance that others will not independently
develop similar technologies or duplicate any technology developed by AXENT or
that AXENT's technology will not infringe upon patents or other rights owned
by others. AXENT's inability to protect its proprietary rights would have a
material adverse effect on AXENT's financial condition and results of
operations.
 
  As the number of information security products in the industry increases and
the functionality of these products further overlaps, software developers and
publishers may increasingly become subject to claims of infringement or
misappropriation of the intellectual property or proprietary rights of others.
There can be no assurance that third parties will not assert infringement or
misappropriation claims against AXENT in the future with respect to current or
future products. Further, AXENT may be subject to additional risk as it enters
into transactions in countries where intellectual property laws are not well
developed or are poorly enforced. Legal protections of AXENT's rights may be
ineffective in such countries, and technology developed in such countries may
not be protectable in jurisdictions where protection is ordinarily available.
Any claims or litigation, with or without merit, could be costly and could
result in a diversion of management's attention, which could have a material
adverse effect on AXENT's financial condition and results of operations.
Adverse determinations in such claims or litigation could also have a material
adverse effect on AXENT's financial condition and results of operations.
 
  POSSIBLE ADVERSE EFFECTS OF SPIN-OFF; DEPENDENCE ON ROYALTIES. Effective
December 31, 1995, AXENT transferred certain operations, assets, liabilities
and foreign subsidiaries related to AXENT's OpenVMS utility
 
                                      23
<PAGE>
 
software business to Raxco Software, Inc. ("Raxco") and distributed shares of
Raxco's convertible preferred stock to AXENT's stockholders (the "Spin-Off").
In connection with the Spin-Off, AXENT granted Raxco exclusive distribution
rights to its OpenVMS utility software products in exchange for the payment of
royalties, pursuant to an exclusive distributor license agreement (the
"Exclusive Distributor License Agreement"). These royalties will continue to
provide significant revenue to AXENT for the foreseeable future. The market
for OpenVMS utility software products is likely to continue to decline over
the next several years due in part to customers migrating from the OpenVMS
operating system to other operating systems including UNIX and Windows NT.
 
  The Exclusive Distributor License Agreement provides for the payment of
royalties equal to the greater of 30% of the gross revenues from the OpenVMS
utility software products or $2.0 million in 1996, $1.5 million in 1997 and
$1.0 million in 1998. If the Spin-Off had occurred as of January 1, 1994, the
royalty that AXENT would have received from Raxco for 1994 and 1995 would have
been $5,217,000 and $4,294,000, respectively. However, such historical
royalties are not indicative of future results, and there can be no assurance
that AXENT will receive even the minimum royalty. AXENT received royalties of
$3,321,000 and $2,267,000 for the year ended December 31, 1996 and the nine
months ended September 30, 1997, respectively, from Raxco under the Exclusive
Distributor License Agreement, which AXENT accounted for as non-operating
income from continuing operations. The failure of Raxco to effectively market
such software products or its inability to pay such royalties could have a
material adverse effect on AXENT's financial condition and results of
operations.
 
  Although the Exclusive Distributor License Agreement provides AXENT with
remedies for Raxco's failure to perform its obligations under the agreement or
to pay the required royalties, there can be no assurance that Raxco will
perform its obligations or pay the required royalties on a timely basis, if at
all. Such remedies include AXENT's right to terminate the agreement upon a
breach by Raxco and upon such termination of the agreement, unless otherwise
agreed by the parties, Raxco will assign any agreements related to the utility
software products to AXENT, and AXENT would have the opportunity to hire Raxco
employees who are considered key to the marketing and technical support of
such products. In the event that the agreement expires by its terms, Raxco
will assign any agreements related to the utility software products to AXENT.
In either event, no assets or liabilities of Raxco will be transferred back to
AXENT when the Exclusive Distributor License Agreement terminates. In
addition, Raxco is subject to a non-competition agreement with AXENT for a
period ending on the earlier to occur of (i) December 31, 2001, or (ii) the
date one year following the termination of the Exclusive Distributor License
Agreement, after which time there can be no assurance that Raxco or its
successor will not become a competitor of AXENT.
 
  Although the results of the business transferred to Raxco have historically
been profitable, there can be no assurance that such results will continue or
that Raxco will be able to continue operating as a stand-alone business.
Failure of Raxco to remain viable or to satisfy its obligations could have a
material adverse effect on AXENT's financial condition and results of
operations.
 
  POSSIBLE VOLATILITY OF SHARE PRICE. The market price of AXENT Common Stock,
which is traded on Nasdaq, may be subject to significant fluctuations in
response to operating results, announcements of technological innovations or
new products by AXENT or its competitors, patent or proprietary rights
developments and market conditions for computer industry stocks in general. In
addition, the stock market in recent years has experienced extreme price and
volume fluctuations that often have been unrelated or disproportionate to the
operating performance of individual companies. These market fluctuations, as
well as general economic conditions, may adversely affect the market price of
AXENT Common Stock. The trading prices of many high technology companies'
stocks are at or near their historical highs and reflect price/earnings ratios
substantially above historical norms. There can be no assurance that the
trading price of AXENT Common Stock will remain at or near its current level.
Additionally, it is likely that in some future quarters AXENT's operating
results will be below the expectations of public market analysts and
investors.
 
  DIVIDENDS. No dividends have been paid on AXENT Common Stock to date and
AXENT does not anticipate paying dividends in the foreseeable future.
 
                                      24
<PAGE>
 
  ANTITAKEOVER PROVISIONS. AXENT's Certificate of Incorporation (the "AXENT
Certificate") requires that any action required or permitted to be taken by
stockholders of AXENT must be effected at a duly called annual or special
meeting of stockholders and may not be effected by any consent in writing,
unless unanimous. Special meetings of stockholders may be called only by the
Chairman of the Board, the Chief Executive Officer or, if none, the President
of AXENT or by the Board of Directors. The AXENT Certificate provides for a
classified Board of Directors, and members of the Board of Directors may be
removed only for cause upon the affirmative vote of holders of at least two-
thirds of the shares of capital stock of AXENT entitled to vote. These
provisions, and other provisions of the AXENT Certificate, may have the effect
of deterring hostile takeovers or delaying or preventing changes in control or
management of AXENT, including transactions in which stockholders might
otherwise receive a premium for their shares over then current market prices.
In addition, these provisions may limit the ability of stockholders to approve
transactions that they may deem to be in their best interests.
 
RISKS RELATING TO RAPTOR
 
  LIMITED OPERATING HISTORY; UNPREDICTABILITY OF OPERATING RESULTS. Raptor was
incorporated in December 1991 but did not begin to generate meaningful revenue
until the first quarter of 1995. Raptor did not generate an operating profit
until the third quarter of 1996. Although Raptor has experienced significant
revenue growth in recent periods, in view of Raptor's short operating history
and the rapidly changing nature of the network security market, such growth
may not be sustainable and should not be considered indicative of future
operating results. Raptor's results of operations may become increasingly
unpredictable from quarter to quarter as a result of numerous factors,
including market acceptance of Raptor's current or future products,
fluctuations in the development and growth of the network security industry in
general, the mix of distribution channels through which Raptor's products are
sold, the timing of orders and shipments of products, Raptor's ability to
introduce new products, or the introduction or the announcement of competitive
products. In addition, a substantial portion of Raptor's revenue occurs during
the last few weeks of each quarter; therefore, any delays in orders or
shipments are more likely to result in revenue not being recognized until the
following quarter. Raptor's current expense levels are based in part on its
expectations of future revenue and, as a result, net income for a given period
could be disproportionately affected by any reduction in revenue. There can be
no assurance that Raptor will be able to achieve significant revenue from
sales of products in the future or that the level of revenue in the future
will not decrease from past levels.
 
  MANAGEMENT OF GROWTH. Raptor recently has experienced significant growth in
both revenue and in employees. This growth has resulted in an increase in the
responsibilities of Raptor's management and has placed added pressures on
Raptor's operating and financial systems. In 1995, Raptor hired 50 new
employees, including certain key members of management, to help it manage this
growth. In 1996, Raptor hired 42 additional employees including a new Chief
Financial Officer. During the nine months ended September 30, 1997, Raptor
increased its employee roster by an additional 18 individuals. Raptor's
ability to assimilate new personnel will be critical to its performance, and
there can be no assurance that the management and systems currently in place
will be adequate if its operations continue to expand or that Raptor will be
able to implement additional systems successfully and in a timely manner as
required.
 
  RISKS ASSOCIATED WITH THE EMERGING NETWORK SECURITY MARKET. The market for
Raptor's products is in an early stage of development. The rapid development
of enterprise-wide and inter-network computing has increased the ability of
users to access proprietary information and resources and has, in recent
years, increased demand for network security products. Because the market for
network security products is only beginning to develop, it is difficult to
assess the size of this market and the product features and prices, the
optimal distribution strategy and the competitive environment that will
develop in this market.
 
  DEPENDENCE ON FIREWALL PRODUCTS; UNCERTAINTY OF PRODUCT ACCEPTANCE. Raptor
derives substantially all of its revenue from its Eagle family of network
security products, all of which are dependent upon Raptor's Eagle application-
level firewall. As a result, any factor adversely affecting sales of this
product could have a material adverse effect on Raptor. While management of
Raptor believes that sales from its firewall product will
 
                                      25
<PAGE>
 
continue to represent the primary source of its revenues, it believes that to
be successful in the future Raptor will need to expand its product offerings
to include an integrated suite of other types of products. Current examples of
such products include Raptor's EagleMobile virtual private networking
technology, its EagleNetwatch visualization product, and its Raptor Axcess
products, an integrated set of technologies that provides secure, centralized
access control to distributed Web-based information. Raptor is actively
engaged in researching and developing additional products to enable it to have
revenue sources that are not subject to the limitations of the firewall
market. There can be no assurance, however, that Raptor will be able to
develop such products or that any such products will achieve market acceptance
in the network security market. The failure of Raptor's products to achieve
such market acceptance, or maintain such acceptance, if achieved, as a result
of competition, technological change or other factors, could have a material
adverse effect on Raptor's business, financial condition and results of
operations.
 
  COMPETITION. The market for network security products and services is new,
intensely competitive, rapidly evolving and subject to rapid technological
change. Raptor expects competition to intensify in the future. Raptor believes
that the principal competitive factors affecting the market for network
security products include security effectiveness, scope of product offerings,
technical features, ease of use, reliability, customer service and support,
distribution channels and price. Although Raptor believes that its products
currently compete favorably with respect to such factors, particularly in the
high-end of the network security market, there can be no assurance that Raptor
will maintain its competitive position against current and potential
competitors, especially those with significantly greater financial, marketing,
service, support, technical and other competitive resources.
 
  Raptor's principal current competitors include Ascend Communications
Corporation, Bay Networks, Inc., CheckPoint Software Technology, Ltd., Cisco
Systems, Inc., Cyberguard, Digital Equipment Corporation, International
Business Machines Corporation, Milkyway Networks Corporation, Network Systems
Corporation, Secure Computing Corporation, Sun Microsystems, Inc., 3Com
Corporation, Trusted Information Systems Inc. and V-One, Inc. Raptor was the
first company to introduce a firewall product that supports Microsoft's
Windows NT operating system. Raptor's Eagle NT firewall product became
commercially available in the first quarter of 1996. Cisco Systems and
CheckPoint Software Technology both introduced Windows NT-based firewalls in
1996, and Microsoft recently introduced a proxy server product which features
firewall-class security. According to a recent report, Raptor was the leading
provider of Windows NT-based firewalls in 1996, and 73% of Raptor's total
product shipments and 62% of its license revenue for the nine months ended
September 30, 1997, were comprised of NT server products. However, there can
be no assurance that Raptor will be able to maintain its position within the
NT-based firewall market in the future. Although Raptor has a large share of
the market for NT-based firewall products, its share of the total firewall
market is smaller than that of Cisco Systems and CheckPoint Software
Technology, each of which derives a significant portion of their firewall
sales from non-Windows NT firewall products. There can be no assurance that
Raptor will not in the future face increased competition from such companies
in the NT firewall market and therefore suffer loss of market share to such
companies. Moreover, due to the rapid expansion of the network security
market, Raptor may face competition from new entrants in the network security
industry, possibly including Raptor's resellers. In addition, a number of
network hardware manufacturers, such as Cisco Systems, are now offering
products with embedded firewalls. There can be no assurance that Raptor's
current and potential competitors will not develop network security products
that may be more effective than Raptor's current or future products or that
Raptor's technologies and products would not be rendered obsolete by such
developments. Many of Raptor's current and potential competitors have longer
operating histories, greater name recognition, larger installed customer bases
and significantly greater financial, technical and marketing resources than
Raptor. As a result, they may be able to adapt more quickly to new or emerging
technologies and changes in customer requirements, or to devote greater
resources to the promotion and sale of their products than Raptor. An increase
in competition could result in price reductions and loss of market share. Such
competition and any resulting reduction in gross margins could have a material
adverse effect on Raptor's business, financial condition and results of
operations.
 
  In addition, several current and potential competitors of Raptor have
established or may in the future establish cooperative relationships among
themselves or with third parties to increase the ability of their products
 
                                      26
<PAGE>
 
to address the security needs of Raptor's prospective customers. Accordingly,
it is possible that new competitors or alliances may emerge and rapidly
acquire significant market share. If this were to occur, the financial
condition or results of operations of Raptor could be materially adversely
affected.
 
  RISK OF NEW PRODUCT INTRODUCTIONS; RISK OF ERRORS OR FAILURES. As the
network security industry continues to evolve, Raptor plans to develop and
introduce new products to address the changing needs of the evolving network
security market. There can be no assurance that Raptor will be able to develop
new products or that such products will achieve market acceptance or, if
market acceptance is achieved, that Raptor will be able to maintain such
acceptance for a significant period of time. Any inability of Raptor to
develop products on a timely basis that address changing customer requirements
may require Raptor to substantially increase development expenditures or may
result in a loss of market share to a competitor. For example, in May 1997,
Raptor acquired exclusive worldwide rights to Open Market Inc.'s Axcess
technology with the intention of using such technology to develop new secure
intranet and authentication products. Raptor is currently engaged in research
and development in connection with use of the Axcess technology and
incorporating such technology in application-ready products. To date, however,
Raptor has yet to introduce any such out-of-the-box applications incorporating
the Axcess technology. There can be no assurance that Raptor will successfully
complete the development of any such products in a timely fashion or that such
products will satisfy the needs of the computer information security market or
achieve market acceptance or, if market acceptance is achieved, that Raptor
will be able to maintain such acceptance for a significant period of time and
maintain continued compatibility with new releases of operating systems and
with new operating systems that may be developed.
 
  Products as complex as those offered by Raptor may contain undetected errors
when first introduced or when new versions are released. Raptor has in the
past discovered software errors in certain of its product offerings after
their introduction and has experienced delays and lost revenue during the
period required to correct these errors. In particular, the personal computer
hardware environment is characterized by a wide variety of non-standard
configurations that makes pre-release testing for programming or compatibility
errors very difficult and time-consuming. There can be no assurance that,
despite testing by Raptor, errors will not occur in new products or releases
after commencement of commercial shipments, resulting in adverse publicity, in
loss of or delay in market acceptance, or in claims by the customer against
Raptor, which could have a material adverse effect on Raptor's business,
financial condition and results of operations.
 
  CHANGES IN TECHNOLOGY AND INDUSTRY STANDARDS. The network security industry
is characterized by rapid changes, including evolving industry standards,
frequent new product introductions, continuing advances in technology and
changes in customer requirements and preferences. The introduction of new
technologies could render Raptor's existing products obsolete or unmarketable.
The development cycle for Raptor's new products may be significantly longer
than Raptor's historical product development cycle, resulting in higher
development costs or a loss in market share. Advances in techniques by
individuals and entities seeking to gain unauthorized access to networks could
expose Raptor's existing products to new and unexpected attacks and require
accelerated development of new products. There can be no assurance that Raptor
will be able to counter challenges to its current products, that Raptor's
future product offerings will keep pace with technological changes implemented
by competitors or persons seeking to reach network security, that its products
will satisfy evolving consumer preferences or that Raptor will be successful
in developing and marketing products for any future technology. Failure to
develop and introduce new products and product enhancements in a timely
fashion could have a material adverse effect on Raptor's business, financial
condition and results of operations.
 
  DEPENDENCE ON RESELLERS. Raptor relies significantly on strategic, regional
and international VARs and master distributors to distribute its products. The
success of Raptor is therefore dependent in large part upon the performance of
its resellers, whose efforts are outside Raptor's control. Raptor currently
has agreements with over 300 resellers who accounted for 81% and 91% of sales
for fiscal 1996 and the nine months ended September 30, 1997, respectively.
Furthermore, Raptor has become particularly dependent upon a small number of
strategic VARs and master distributors for an increasingly significant amount
of its revenue, including MicroAge Computer Centers, Inc., Access Graphics
Inc., Tech Data Product Management, Inc., Ingram Micro Inc. and Hewlett-
Packard Company. Such strategic VARs and master distributors collectively
accounted for 13%
 
                                      27
<PAGE>
 
of Raptor's sales for the quarter ended September 30, 1997. The loss of any of
Raptor's major resellers, either to competitive products offered by other
companies or to products developed internally by the resellers, could have a
material adverse effect on Raptor. Moreover, Raptor's future success will
depend in part on its ability to attract new resellers. Raptor's agreements
with certain of these resellers allow them to terminate such contracts in the
event of a change of control of Raptor or otherwise upon advance notice. Any
such termination of a contract with a significant reseller could have an
adverse effect on Raptor's financial condition and results of operations.
Furthermore, as Raptor seeks to expand its product focus to firewalls for
high-end UNIX-based systems and sophisticated intranet security technologies,
it is likely to pursue more sophisticated network security customers.
Similarly, as Raptor develops products that require increased implementation
consulting services, such as products utilizing the Axcess technology acquired
from Open Market, Inc., it is likely to rely more heavily on direct sales
efforts to attract customers for such products. There can be no assurance that
Raptor will be successful in attracting and retaining necessary sales and
consulting personnel, or that once hired, such personnel will successfully
implement Raptor's strategy.
 
  DEPENDENCE ON EXTERNAL DEVELOPMENT RESOURCES AND SUPPLIERS. Raptor has
relied and will continue to rely on external development resources for the
development of certain of its products and components thereof. Raptor's
success will depend in part on its continued ability to obtain and renew
product development agreements with independent software developers. There can
be no assurance that Raptor will be able to obtain or renew product
development agreements on favorable terms or at all. Due primarily to the
increased demand for software programs, the payment of advance and guaranteed
royalties to independent developers has increased and may continue to
increase. As independent developers are in high demand, there can be no
assurance that independent developers, including those who have developed
products for Raptor in the past, will be available to develop products for
Raptor in the future. Many independent developers have limited financial
resources, which could expose Raptor to the risk that such developers may go
out of business prior to completing a project. In addition, due to the fact
that Raptor has less control over the scheduling and quality of the work of
independent developers than it does over its own employees, there can be no
assurance that such developers will complete products for Raptor on a timely
basis, within acceptable guidelines or at all.
 
  INTERNATIONAL SALES RISKS. Sales outside the United States accounted for
approximately 17% and 21% of Raptor's net revenues from its information
security products in the year ended December 31, 1996 and the nine months
ended September 30, 1997, respectively. Of such international sales, sales in
Asia accounted for approximately 7% and 10% of Raptor's net revenues in the
year ended December 31, 1996 and the nine months ended September 30, 1997,
respectively. Management expects that international sales will continue to
generate a significant portion of Raptor's total revenue. To date, all sales
outside the United States have been transacted in United States dollars and as
a result have not been subject to risks associated with currency fluctuations.
As Raptor pursues international sales, currency fluctuations could make
Raptor's products less competitive in foreign markets and contribute to
fluctuation in Raptor's operating results. Other risks affecting international
sales include political instability, difficulties in staffing and managing
international operations, potential insolvency of international resellers,
longer receivable collection periods and difficulty in collecting accounts
receivable. In addition, the laws of certain countries do not protect Raptor's
products and intellectual property rights to the same extent as the laws of
the United States. There can be no assurance that these factors will not have
a material adverse effect of Raptor's business, financial condition and
results of operations.
 
  EFFECT OF GOVERNMENTAL REGULATION OF TECHNOLOGY EXPORTS. Raptor's
international sales and operations may be subject to risks such as the
imposition of governmental controls, new or changed export and import license
requirements, restrictions on the export of critical technology, trade
restrictions and changes in tariffs. While Raptor believes its products are
designed to meet the regulatory standards of foreign markets, any inability to
obtain foreign regulatory approvals on a timely basis could have a material
adverse effect on Raptor's financial condition or results of operations.
Certain of Raptor's products are subject to export controls under U.S. law,
and Raptor believes it has obtained all necessary export approvals when
required. There can be no assurance, however, that the list of products and
countries for which export approval is required, and the regulatory policies
with respect thereto, will not be revised from time to time. The inability of
Raptor to obtain required approvals
 
                                      28
<PAGE>
 
under these regulations could materially adversely affect the ability of
Raptor to make international sales. In particular, because of governmental
controls on the exportation of encryption technology, Raptor is unable to
export its most robust network security products. As a result, foreign
competitors that face less stringent controls on their products may be able to
compete more effectively than Raptor in the global network security market.
There can be no assurance that these factors will not have a material adverse
effect on Raptor's business, financial condition and results of operations. In
addition, certain countries into which Raptor imports its products have import
and other restrictions on security software products. Any failure to comply
with such regulations could have an adverse effect on Raptor's business,
financial condition and results of operations.
 
  LIMITED PROTECTION OF INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS. Raptor's
success is dependent in part upon its proprietary software and security
technology. Raptor relies on copyright and trade secret laws, employee and
third-party non-disclosure agreements and other methods to protect its
proprietary rights. Raptor currently has four patent applications pending in
the United States relating to certain aspects of its technology. There can be
no assurance that any pending or future patent applications will be granted or
that any future patents will not be challenged, invalidated or circumvented or
that the rights granted thereunder will provide competitive advantages to
Raptor. Raptor believes that, due to the rapid pace of technological
innovation for network security products, Raptor's ability to establish and
maintain a position of technology leadership in the industry is dependent more
upon the skills of its development personnel than upon the legal protections
afforded its existing technology. There can be no assurance, however, that
Raptor's trade secrets or non-disclosure agreements will provide meaningful
protection of Raptor's proprietary information. Furthermore, there can be no
assurance that others will not independently develop similar technologies or
duplicate any technology developed by Raptor. Raptor's inability to protect
its proprietary rights would have a material adverse effect on Raptor's
business, financial condition and results of operations. Further, Raptor may
be subject to additional risk as it enters into transactions in countries
where intellectual property laws are not well developed or are poorly
enforced. Legal protections of Raptor's rights may be ineffective in such
countries.
 
  As the number of network security products in the industry increases and the
functionality of these products further overlaps, software developers and
publishers may increasingly become subject to infringement claims. There can
be no assurance that third parties will not assert infringement claims against
Raptor in the future with respect to current or future products. Although
Raptor is not currently the subject of any intellectual property litigation,
there has been substantial litigation regarding patent, copyright, trademark
and other intellectual property rights involving computer software companies.
Any claims or litigation, with or without merit, could be costly and could
result in a diversion of management's attention, which could have a material
adverse effect on Raptor's business, financial condition and results of
operations. Adverse determinations in such claims or litigation could also
have a material adverse effect on Raptor's business, financial condition and
results of operations.
 
  DEPENDENCE ON LICENSED TECHNOLOGY. Raptor relies on outside licensors for
certain technology that is incorporated into and is necessary for the
operation of Raptor's products. Raptor's success will depend in part on its
continued ability to license technologies that are or may be important to the
functionality of its products. An inability to continue to procure or use such
technology could have a material adverse effect on Raptor's business,
financial condition and results of operations.
 
CONFLICTS OF INTEREST OF CERTAIN OFFICERS, DIRECTORS AND STOCKHOLDERS OF
RAPTOR
 
  In considering the recommendation of the Raptor Board with respect to the
Merger, the Merger Agreement and the transactions contemplated thereby, the
holders of Raptor Common Stock should be aware that certain members of the
Raptor Board and the management of Raptor have certain interests in, and will
receive benefits from, the Merger that are different from, or in addition to,
the interests of, and benefits to, the holders of Raptor Common Stock
generally. See "The Merger--Interests of Certain Persons in the Merger." The
Raptor Board of Directors was aware of the these conflicts of interest and
benefits, and considered them, among other matters, in deciding whether to
approve the Merger, the Merger Agreement and the transactions contemplated
thereby.
 
                                      29
<PAGE>
 
  In connection with the Merger:
 
    1. Raptor entered into severance, consulting and/or bonus agreements with
  certain employees and executive officers, two of whom are also members of
  its Board of Directors. Raptor has entered into Severance Agreements, that
  become effective upon the date that the Merger is consummated, with certain
  executive officers (and other director-level and above employees) that
  provide, among other things, that if such person's employment is terminated
  other than for Cause (as defined in the Severance Agreements), or the
  employee resigns for Good Reason (as defined in the Severance Agreements),
  during a range of time periods (depending upon the person's level of
  employment), such employee has a right to receive a lump-sum severance
  payment, and continued health and dental benefits for the same period. Such
  lump sum severance payments aggregate approximately $1,000,000 to certain
  executive officers of Raptor assuming no change in current base salary
  levels, in the following amounts: six (6) months for director-level
  employees, nine (9) months for vice-presidents, one (1) year for the chief
  executive officer, chief financial officer and senior vice-presidents, or
  two (2) years for the Chairman of the Raptor Board, of base salary as then
  in effect.
 
    2. Raptor also has entered into Consulting Agreements, that become
  effective upon the date that the Merger is consummated, with Mr. Shaun
  McConnon, Chief Executive Officer of Raptor and a member of the Raptor
  Board and Mr. John Ingalls, Chief Financial Officer of Raptor, pursuant to
  which Raptor, or any successor entity, will pay consulting payments
  (aggregating $740,000) in consideration of certain consulting services that
  such individuals will provide to Raptor, AXENT and/or the Surviving
  Corporation in connection with the Merger and the integration of the
  respective businesses of Raptor and AXENT.
 
    3. Raptor entered into Bonus Agreements, which become effective upon the
  date that the Merger is consummated, that provide certain executive
  officers and employees of Raptor with bonus payments (aggregating
  approximately $1,300,000) at certain dates after the consummation of the
  Merger. Pursuant to the terms of the Bonus Agreements, each employee is
  entitled to receive his or her entire bonus payment unless he or she
  voluntarily resigns without Good Reason (as defined in the Bonus
  Agreements), in which case he or she would forfeit any bonus not yet
  earned.
 
  In addition, as of December 19, 1997, options to purchase a total of 649,287
shares of Raptor Common Stock held by certain executive officers of Raptor and
non-employee members of the Raptor Board were outstanding and not vested and
will become fully vested and immediately exercisable in connection with the
Merger. In the event that the executive officers and/or non-employee members
of the Raptor Board exercise such options, then, assuming a $13.20 per share
price of Raptor Common Stock (the closing price of AXENT Common Stock on
December 19, 1997 multiplied by the Conversion Ratio), the aggregate value
(net of exercise price) to the holders of such options would be approximately
$7,069,781. Additional options to purchase shares of Raptor Common Stock have
been issued to certain executive officers of Raptor which will be canceled
upon consummation of the Merger. As of December 19, 1997, the four non-
employee members of the Raptor Board owned an aggregate of 24,000 shares of
restricted Raptor Common Stock (the "Raptor Restricted Stock"). According to
the terms of such Raptor Restricted Stock, the restrictions on all of such
Raptor Restricted Stock will lapse in connection with the Merger. Assuming a
$13.20 per share price of Raptor Common Stock (the closing price of AXENT
Common Stock on December 19, 1997 multiplied by the Conversion Ratio), the
aggregate value to the holders of such Raptor Restricted Stock (net of the
purchase price) would be approximately $304,800. See "The Merger--Interests of
Certain Persons in the Merger."
 
PAYMENTS IF THE MERGER AGREEMENT IS TERMINATED
 
  No assurance can be given that the Merger will be consummated. The Merger
Agreement provides for the payment by Raptor of a termination fee of
$8,850,315 if the Merger Agreement is terminated under certain circumstances.
Such payment obligations may adversely affect the ability of Raptor to engage
in another transaction in the event that the Merger is not consummated and may
have an adverse impact on the financial condition of Raptor. See "The Merger
Agreement--Termination."
 
NO APPRAISAL RIGHTS IN CONNECTION WITH MERGER
 
  The holders of Raptor Common Stock do not have appraisal rights in
connection with the Merger under Delaware law. See "The Raptor Special
Meeting--Appraisal Rights."

the outstanding shares of the AXENT Common Stock issued and outstanding and
entitled to vote at the AXENT Special Meeting is necessary to constitute a
quorum at the AXENT Special Meeting. The affirmative vote of the holders of a
majority of the outstanding shares of AXENT Common Stock, present in person or
by proxy at the Special Meeting considering such matter, is required to
approve (i) the AXENT Share Proposal; (ii) the Stock Purchase Plan; and (iii)
the Option Plan. Abstentions will be treated as shares that are present and
entitled to vote for the purposes of determining a quorum and as negative
votes against the approval of the foregoing. "Broker non-votes" will not be
considered as present and will not be counted for or against approval of the
foregoing.
 
                                      31
<PAGE>
 
  As of the AXENT Record Date, AXENT's directors, executive officers and their
affiliates held approximately     or  %, of the outstanding shares of AXENT
Common Stock entitled to vote at the AXENT Special Meeting. Certain
stockholders of AXENT, who as of the AXENT Record Date, held in the aggregate
approximately  % of the outstanding AXENT Common Stock, have entered into

BOARD OF DIRECTORS RECOMMENDATION
 
  For the reasons described in this Prospectus/Joint Proxy Statement, the
Raptor Board has unanimously approved the Merger Agreement and the Merger. The
Raptor Board believes that the Merger is fair to, and in the best interests
of, Raptor and the Raptor stockholders and unanimously recommends that the
Raptor stockholders vote FOR approval of the Merger Agreement, the Merger and
the transactions contemplated thereby. In making its recommendation, the
Raptor Board considered, among other things, the opinion of Montgomery that
the consideration to be paid is fair to the Raptor stockholders from a
financial point of view. See "The Merger and the AXENT Share Proposal--
Background of the Merger," "--Reasons for the Merger" and "--Opinions of
Raptor's Financial Advisor."
 
DATE, TIME AND PLACE
 
  The Raptor Special Meeting is scheduled to be held on February 5, 1998 at
10:00 a.m., local time, at the offices of Goodwin, Procter & Hoar LLP,
Exchange Place, Boston, Massachusetts.
 
RECORD DATE; SHARES OUTSTANDING
 
  The Raptor Board has fixed the close of business on December 31, 1997 as the
Raptor Record Date for the determination of Raptor stockholders entitled to
notice of and to vote at the Raptor Special Meeting and at any adjournments or
postponements thereof.
 
  On the Raptor Record Date, there were outstanding     shares of Raptor
Common Stock held by approximately     stockholders of record.
 
VOTING AT THE RAPTOR SPECIAL MEETING
 
  The presence, either in person or by proxy, of the holders of a majority of
the outstanding shares of the Raptor Common Stock issued and outstanding and
entitled to vote at the Raptor Special Meeting is necessary to constitute a
quorum at the Raptor Special Meeting. The affirmative vote of the holders of a
majority of the outstanding shares of Raptor Common Stock is required to
approve the Merger Agreement and the Merger. Abstentions and "broker-non
votes" will have the effect of votes against approval of the foregoing, but
will be counted as shares present in connection with determining whether a
quorum exists at the Raptor Special Meeting.
 
  As of the Raptor Record Date, Raptor's directors, executive officers and
their affiliates held approximately     or  % of the outstanding shares of
Raptor Common Stock entitled to vote at the Raptor Special Meeting. Certain
stockholders of Raptor, who as of the Raptor Record Date held in the aggregate
approximately  % of the outstanding Raptor Common Stock, have entered into
Voting and Support Agreements providing, among other things, to vote such
shares in favor of the Merger and the Merger Agreement. See "The Merger--
Voting and Support Agreements."

  When a proxy is returned properly signed and dated, the shares represented
thereby will be voted in accordance with the instructions on the proxy. If a
stockholder does not return a signed proxy, the shares will not be voted.
Stockholders are urged to mark the boxes on the proxy to indicate how their
shares are to be voted. IF A STOCKHOLDER RETURNS A SIGNED PROXY, BUT DOES NOT
INDICATE HOW SUCH HOLDER'S SHARES ARE TO BE VOTED, THE SHARES REPRESENTED BY
THE PROXY WILL BE VOTED FOR THE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT
AND THE MERGER.
 
  Attendance at the Raptor Special Meeting will not in and of itself
constitute revocation of a proxy. The proxy may be revoked in writing by the
person giving it at any time before it is exercised by giving such notice to
the Secretary of Raptor or by submitting a proxy bearing a later date, or by
such person appearing at the Special Meeting and voting in person. All proxies
validly submitted and not revoked will be voted in the manner specified.
 
  The Raptor Board is not currently aware of any matters to come before the
Raptor Special Meeting other than as described herein. If, however, other
matters are properly brought before the Raptor Special Meeting, including
among other things consideration of a motion to adjourn the Raptor Special
Meeting to another time and/or place (including without limitation for the
purpose of soliciting additional proxies), the persons appointed as the named
proxies will have discretion to vote or act thereon according to their best
judgment.
 
SOLICITATION OF PROXIES
 
  Raptor will bear the costs of soliciting proxies from the Raptor
stockholders. In addition to solicitation by mail, directors, officers and
employees of Raptor, who will not be compensated for such services, may
solicit proxies from Raptor stockholders personally or by telephone, telecopy
or telegram or other forms of communication. Arrangements also will be made
with brokerage firms and other custodians, nominees and fiduciaries for the
forwarding of solicitation materials to the beneficial owners of Raptor Common
Stock held of record by such persons, and such persons will be reimbursed for
their reasonable expenses incurred in that effort by Raptor. MacKenzie
Partners, Inc. has been engaged by Raptor to act as proxy solicitors and to
mail proxies to the holders of Raptor Common Stock on the Raptor Record Date
and will receive a fee in connection therewith of approximately $6,000.
 
APPRAISAL RIGHTS
 
  Holders of Raptor Common Stock will be not be entitled to appraisal rights
in connection with the approval and adoption of the Merger Agreement and the
Merger.

              PROPOSAL I: THE MERGER AND THE AXENT SHARE PROPOSAL
 
BACKGROUND OF THE MERGER
 
  AXENT has maintained an active program of expansion through its acquisition
of products and businesses and its exploration of collaborative relationships
throughout its history. As part of its monitoring of possible candidates for
acquisition or collaborative relationship, AXENT has followed Raptor and has
recognized that Raptor's products, technologies and marketing and distribution
channels are complementary to those of AXENT.
 
  During May and June of 1996, Richard Lefebvre, AXENT's Chairman of the Board
and then Chief Executive Officer and Robert Steinkrauss, Raptor's Chairman of
the Board and then Chief Executive Officer, and other representatives of AXENT
and Raptor met or exchanged information on several occasions relating to a
collaborative relationship between the two companies, including reselling and
distribution arrangements.
 
  By letter dated June 28, 1996 to Mr. Lefebvre, Mr. Steinkrauss outlined a
potential combination of the two companies. Messrs. Lefebvre and Steinkrauss
continued discussions regarding a possible combination of the two companies
throughout July and into August. On August 6, 1996, Mr. Lefebvre received a
letter from Mr. Steinkrauss outlining Raptor's proposed acquisition of AXENT
("Raptor Initial Proposal"). Meetings and conversations between
representatives of AXENT and Raptor continued.
 
  On September 18, 1996, the Raptor Board reviewed a number of acquisition and
investment opportunities, including AXENT, at which point Mr. Steinkrauss
reported that AXENT had declined to pursue a business combination with Raptor.
Throughout the month of October, 1996, Messrs. Lefebvre and Steinkrauss as
well as John Becker, then Chief Operating Officer of AXENT, and other
representatives of AXENT and Raptor continued to meet and exchange information
relating to each company's strategic vision and purpose, and desire to enter
into a collaborative relationship. By letter dated October 21, 1996, Mr.
Steinkrauss again expressed Raptor's interest in pursuing a business
combination ("Raptor Second Proposal"). At a regularly scheduled meeting of
the AXENT Board on October 22, 1996, the AXENT Board determined that AXENT
management should not pursue the Raptor Second Proposal. Discussions
concerning a potential business combination between the two companies halted
by the end of October 1996. At the November 21, 1996 regularly scheduled
Raptor Board meeting, Mr. Steinkrauss reviewed Raptor's acquisition and
investment opportunities, which included AXENT. Mr. Steinkrauss informed the
Raptor Board that AXENT had declined the Raptor Second Proposal.
 
  The companies discontinued business discussions until June 23, 1997, when
Shaun McConnon, Raptor's President and current Chief Executive Officer, and
other members of Raptor's management met Mr. Becker and other members of
AXENT's management to discuss a potential licensing agreement. By letter dated
July 21, 1997, Erich Baumgartner, Jr., Vice President of Raptor, transmitted a
formal proposal for a strategic alliance between the two companies in the form
of a distribution arrangement. The companies discussed the terms under which
AXENT would distribute Raptor's products.
 
  On July 29, 1997, AXENT engaged Broadview to assist AXENT in pursuing a
corporate development program.
 
  On September 3, 1997, Messrs. Becker and McConnon discussed each company's
strategy and the benefits of a business combination between the two entities.
At that time, Raptor and AXENT entered into a Bi-Lateral Non-Disclosure
Agreement relating to disclosure and other covenants. Throughout the first
half of September, representatives of Raptor and AXENT continued to discuss
the possibility of a business combination and exchange information related
thereto. Mr. Becker transmitted for discussion an outline of a preliminary
structure of an acquisition of Raptor by AXENT to Mr. McConnon on September
15, 1997.
 
  During September 1997, representatives of AXENT and Raptor continued to
discuss a potential acquisition of Raptor by AXENT. At a September 19, 1997
regularly scheduled Raptor Board meeting, the Raptor Board discussed and
reviewed the AXENT proposal and certain other opportunities for a business
combination involving Raptor, but did not take any action in that regard.
 
                                      35
<PAGE>
 
  On October 22, 1997, at a regularly scheduled AXENT Board meeting, the AXENT
Board discussed strategic alternatives and possible acquisition candidates
including Raptor. The AXENT Board determined a transaction with Raptor was not
likely and directed management to pursue other identified acquisition targets.
 
  On October 29, 1997, representatives of AXENT and Raptor again met and
further discussed a potential transaction and conducted preliminary due
diligence investigations relating to engineering and product synergies and
financial matters. Montgomery was involved in the discussions with Raptor and
AXENT in October 1997 and was engaged to act as financial advisor to Raptor on
November 13, 1997. On November 14, 1997, management of Raptor met with
Raptor's accountants and attorneys to develop a strategy for the negotiations.
 
  On November 18, 1997 representatives of AXENT and Raptor held a joint
meeting with their respective financial and legal advisors to discuss the
structure of a business combination between the companies, and identify the
issues which would have to be resolved in order for a transaction to occur.
 
  On November 19, 1997, Mr. Becker submitted to Raptor a new discussion
outline of a transaction pursuant to which AXENT again proposed a merger of
AXENT and Raptor at a Conversion Ratio significantly below the ratio finally
presented in the Merger Agreement. Additionally, AXENT directed its legal
counsel to commence preparation of definitive documentation for the proposed
transaction. Although the parties had differences on a number of material
terms, including the Conversion Ratio, the precise terms of termination rights
and termination fees, the provision of severance benefits, the conduct of each
party's operations between signing and closing of the Merger, and various
corporate governance issues, management of AXENT and Raptor believed that
negotiations had proceeded to a point where the remaining issues should be
addressed in the context of negotiations over definitive documentation.
 
  On November 20, 1997, the Raptor Board, together with its management and
financial and legal advisors, held a telephonic meeting to review, among other
things, the Conversion Ratio and other terms proposed by AXENT, the status of
negotiations on the structure of a business combination, and a proposed
timetable for negotiating and completing the proposed transaction.
 
  On November 21, 1997, the AXENT Board, together with its management and
financial and legal advisors, held a telephonic meeting to review, among other
things, principal terms of the proposed transaction, the status of
negotiations and a proposed timetable for negotiating and completing the
proposed transaction. The AXENT Board authorized Mr. Becker to continue his
negotiations with Mr. McConnon on certain terms. Also on November 21, 1997,
representatives of AXENT's management continued due diligence of Raptor.
 
  After the circulation of initial drafts of various definitive documentation
and the exchange of comments on certain of those drafts, representatives of
Raptor's and AXENT's management and their financial and legal advisors
participated in a telephonic meeting in the morning of November 24, 1997, to
continue negotiations of the outstanding issues.
 
  Also on November 24, 1997, Raptor's Board held a meeting in Boston,
Massachusetts to discuss the status of the Merger Agreement and outstanding
issues related to the same. During the meeting, Raptor's management and its
accountants and financial and legal advisors reviewed the terms of the
proposed transaction. Messrs. Becker and Lefebvre, together with two other
representatives of AXENT's senior management, attended the meeting and gave a
presentation regarding AXENT and their plans for the proposed combined entity
and answered questions from the Raptor Board. Montgomery also reviewed with
the Raptor Board the financial aspects of the proposed transaction, including
the Conversion Ratio, and the valuation methodologies being utilized by
Montgomery in connection with its financial analysis of the proposed
transaction. At this Raptor Board meeting, Raptor's legal advisors and
accountants reviewed certain issues regarding the proposed transaction. Among
other matters, Raptor's management and Board determined that (i) in
recognition of Raptor employee contributions and the need to retain key
employees through the pendency of the transaction, satisfactory severance
arrangements should be instituted, and (ii) the amount of the termination fee
should be reduced and the events upon which the termination fee would be
triggered should be minimized.

  Following the Raptor Board meeting on November 24, 1997, telephonic
negotiations between AXENT and Raptor and their respective financial and legal
advisors continued. Representatives of AXENT's management continued their due
diligence investigation of Raptor on November 25, 1997.
 
  On November 28, 1997, after the close of the stock market, the Raptor Board,
together with Raptor's management and its financial and legal advisors, held a
telephonic meeting to discuss the progress of negotiations of the Merger. At
this meeting, Raptor's management and its financial and legal advisors updated
the Raptor Board on the status of negotiations. Mr. McConnon briefed the
Raptor Board on the Conversion Ratio that he had negotiated with Mr. Becker,
as well as other key issues under discussion and the relative positions of the
parties with respect to such issues. The key issues included (i) whether
Raptor employees would be provided satisfactory severance arrangements and
(ii) the amount of the termination fee and the events upon which the
termination fee would be triggered. During this meeting, Montgomery updated
the Raptor Board with respect to Montgomery's financial analysis of the
proposed transaction and delivered its fairness opinion that, as of such date
and based upon and subject to certain matters stated in such opinion, the
consideration paid in the Merger was fair, from a financial point of view, to
the stockholders of Raptor. Also on November 28, substantially complete drafts
of the definitive documents relating to the Merger were distributed to the
Raptor Board. After deliberation of these issues by the Raptor Board, the
directors discussed with Mr. McConnon acceptable parameters within which such
issues were authorized to be resolved and authorized management to complete
negotiations of the Merger Agreement. The Raptor Board found that the Merger
Agreement and the transactions related thereto were fair and in the best
interests of the stockholders of Raptor, and unanimously approved the Merger
Agreement and the transactions related thereto.
 
  On November 29, 1997, legal counsel and the accountants for AXENT and Raptor
participated with management of the two companies in continued negotiations on
the Merger Agreement and financial aspects of the final proposed terms of the
transaction.
 
  On November 30, 1997, the AXENT Board held a special meeting to consider the
proposed Merger Agreement. At the AXENT Special Meeting, Mr. Becker, together
with members of AXENT's management and AXENT's financial and legal advisors
reviewed with the AXENT Board the results of their due diligence
investigations and the terms of the proposed Merger Agreement. In addition,
Broadview delivered to the AXENT Board its oral opinion (which opinion was
subsequently confirmed by delivery of a written opinion dated November 30,
1997) that, as of such date and based upon and subject to certain matters
stated in such opinion, the consideration paid in the Merger was fair, from a
financial point of view, to the stockholders of AXENT. See "--Opinion of
AXENT's Financial Advisor." Substantially complete drafts of the definitive
documents relating to the Merger had been distributed to the AXENT Board in
preparation for the November 30, 1997 meeting. After discussions, the AXENT
Board found that the Merger Agreement and the transactions related thereto
were fair and in the best interests of the stockholders of AXENT and
unanimously approved the Merger Agreement and authorized AXENT to enter into
the Merger Agreement.
 
  On November 30, 1997, Raptor's management and its legal advisors
participated in a telephonic meeting to inform the Raptor Board that the AXENT
Board had approved the proposed transaction, the final terms of which were
within the parameters authorized by the Raptor Board on November 28, 1997.
 
  Preparation of final versions of the Merger Agreement and related documents
continued through the evening of November 30. On December 1, 1997, the Merger
Agreement and related documents were executed and delivered, and AXENT and
Raptor issued a joint public announcement of the Merger and the transactions
related thereto.
 
RECOMMENDATION OF THE RAPTOR AND AXENT BOARDS
 
  THE RAPTOR AND AXENT BOARDS UNANIMOUSLY RECOMMEND THAT THE STOCKHOLDERS OF
RAPTOR AND AXENT, RESPECTIVELY, VOTE FOR APPROVAL AND ADOPTION OF THE MERGER
AND MERGER AGREEMENT FOR THE REASONS SET FORTH BELOW.
 
                                      37

REASONS FOR THE MERGER
 
 AXENT
 
  The AXENT Board unanimously approved the Merger Agreement and the Merger at
a meeting of the AXENT Board on November 30, 1997. THE AXENT BOARD BELIEVES
THAT THE TERMS OF THE MERGER ARE IN THE BEST INTERESTS OF AXENT AND ITS
STOCKHOLDERS AND RECOMMENDS THAT THE STOCKHOLDERS OF AXENT VOTE "FOR" APPROVAL
OF THE MERGER.
 
  In unanimously approving the Merger Agreement and in recommending that
AXENT's stockholders approve the Merger, the AXENT Board consulted with
AXENT's management, as well as its financial and legal advisors, and
considered a number of factors. The material factors considered by the AXENT
Board in reaching the foregoing conclusions are described below.
 
   (i)    The competitive advantage of offering a more comprehensive product
          line including both AXENT's OmniGuard products and Raptor's firewall
          and other network security products.
 
   (ii)   AXENT's ability to sell many of its products through Raptor's
          traditional VAR, OEM and distributor channels, using Raptor's
          experienced indirect channel managers, as well as AXENT's indirect
          channel and large direct sales force.
 
   (iii)  AXENT's ability to sell many of Raptor's products through AXENT's
          direct sales force and indirect channel.
 
   (iv)   AXENT's desire to add an experienced development team that would
          continue to develop new information security solutions and would work
          with AXENT's development staff to integrate Raptor's products with
          AXENT's existing products.
 
   (v)    The benefits of becoming a larger consolidated organization with
          access to significantly greater financial, development, distribution
          channel and other resources to address the information security needs
          of end users.
 
   (vi)   Information concerning the historical financial performance, business
          operations, financial condition and prospects of Raptor including
          Raptor's periodic reports filed with the Commission.
 
   (vii)  The financial condition, results of operations and business of Raptor,
          on both a historical and prospective basis, as well as current
          industry, economic and market conditions.
 
   (viii) The AXENT Board considered the significant consolidation and
          realignment occurring in the industry and its view that AXENT must
          acquire additional products and technology in order to maintain its
          position as a leading source for enterprise security with a broad
          set of information security products.
 
   (ix)   The financial terms of the Merger, including the proposed structure as
          a tax-free reorganization, and the Conversion Ratio.
 
   (x)    The financial presentation and oral opinion of Broadview rendered to
          the AXENT Board at its November 30, 1997 meeting (which opinion was
          subsequently confirmed by delivery of a written opinion dated November
          30, 1997) to the effect that as of the date of such opinion and based
          upon and subject to certain matters stated therein, the Conversion
          Ratio was fair, from a financial point of view, to the holders of
          AXENT Common Stock. See Annex B.
 
   (xi)   The expectation that the Merger would be accounted for under the
          pooling-of-interests method of accounting.
 
  The AXENT Board also considered the following potentially negative factors
in its deliberations concerning the Merger:
 
  (i)     The various conditions to Raptor's obligations to consummate the
          Merger.
 
  (ii)    AXENT's failure to obtain Voting and Support Agreements from holders
          of a majority of outstanding Raptor Common Stock.
 
                                      38
<PAGE>
 
  (iii)  The fact that under the terms of the Merger Agreement, Raptor's Board
         could consider and approve an alternative transaction and, in certain
         circumstances, AXENT would only be entitled to a termination fee of
         $8,850,316.
 
  (iv)   The risks associated with having the deal value being expressed as a
         set number of shares of AXENT Common Stock, regardless of the value
         thereof at the Effective Time of the proposed Merger.
 
  (v)    The risk that the trading price of AXENT Common Stock might be
         adversely affected by the announcement of the Merger.
 
  (vi)   The charges expected to be incurred in connection with the Merger,
         including costs of integrating the business, transaction expenses
         arising from the Merger and severance, bonus and consulting payments to
         Raptor executives.
 
  (vii)  The risk that the Merger would not be consummated following the
         public announcement thereof.
 
  (viii) The risks of the combined entity suffering employee attrition from
         former Raptor personnel and of failing to retain key personnel due
         to uncertainties associated with the pending Merger.
 
  (ix)   The potential effect of the Merger on collaborative arrangements
         between AXENT and certain competitors of Raptor, as well as the
         potential for delay or disruption of collaborative arrangements between
         AXENT and other companies.
 
  (x)    The potential disruption of the business of either company that might
         result from employee uncertainty and lack of focus following
         announcement of the Merger and during the integration of the operations
         of AXENT and Raptor.
 
  (xi)   The difficulty of managing separate operations in distant geographic
         locations.
 
  (xii)  The risk that, despite the intentions and the efforts of the parties
         to support their respective products, the announcement of the Merger
         could result in decisions by customers to defer purchases of products
         of AXENT or Raptor.
 
  (xiii) The other risks described under "Risk Factors."
 
  In the opinion of the AXENT Board, the above factors represent the material
potential adverse consequences that could occur as a result of the Merger. In
considering the Merger and the transactions related thereto, the AXENT Board
considered the impact of these factors on AXENT's existing stockholders. In
the opinion of the AXENT Board, however, these potentially negative factors
were outweighed by the potential positive factors considered by the AXENT
Board which are described above. Accordingly, the AXENT Board voted to approve
the Merger Agreement and the transactions related thereto.
 
  In view of the wide variety of factors considered in connection with its
evaluation of the Merger, the AXENT Board did not find it practicable to, and
did not, quantify or otherwise attempt to assign relative weights to the
specific factors considered in reaching its determination.
 
 Raptor
 
  The Raptor Board unanimously approved the Merger Agreement and the Merger at
a meeting of the Raptor Board on November 28, 1997. THE RAPTOR BOARD BELIEVES
THAT THE TERMS OF THE MERGER ARE IN THE BEST INTERESTS OF RAPTOR AND ITS
STOCKHOLDERS AND RECOMMENDS THAT THE STOCKHOLDERS OF RAPTOR VOTE "FOR"
APPROVAL OF THE MERGER.
 
  In unanimously approving the Merger Agreement and in recommending that
Raptor's stockholders approve the Merger, the Raptor Board consulted with
Raptor's management, as well as its financial and legal advisors, and
considered a number of factors. The material factors considered by the Raptor
Board in reaching the foregoing conclusions are described below.
 
   (i)   The competitive advantage of offering a more comprehensive product
         line including both AXENT's OmniGuard products and Raptor's firewall
         products and other network security software products.
 
                                      39
<PAGE>
 
   (ii)   Raptor's ability to sell its products to AXENT's end-user customer
          base using AXENT's larger, experienced sales force in addition to
          continuing to sell through Raptor's traditional VAR and OEM customer
          base.
 
   (iii)  Based upon the Conversion Ratio and the closing price of AXENT Common
          Stock on November 28, 1997 (the last trading day prior to the public
          announcement of the Merger), the holders of Raptor Common Stock would
          receive a premium over the closing price of Raptor Common Stock on
          November 28, 1997.
 
   (iv)   The need for rapid expansion of Raptor's product line, employee and
          management base and infrastructure in order to continue to develop new
          electronic security solutions increasingly demanded by corporate and
          network users to enable secure electronic commerce over the rapidly
          evolving Internet and intranets.
 
   (v)    The benefits of becoming a wholly-owned subsidiary of AXENT, including
          giving Raptor access to the significantly greater financial,
          development, personnel and other resources of a larger consolidated
          organization that should enable it to more effectively address the
          information security needs of and compete in the rapidly expanding and
          evolving Internet and intranet markets.
 
   (vi)   Information concerning the historical financial performance, business
          operations, financial condition and prospects of AXENT. Raptor's Board
          reviewed information regarding AXENT, which included AXENT's periodic
          reports filed with the Commission. In addition, Raptor's Board
          interviewed AXENT's management regarding AXENT's revenues, products,
          business strategy and prospects and the market for the proposed
          combined entity's products.
 
   (vii)  The financial condition, results of operations and business of Raptor,
          on both a historical and prospective basis, as well as current
          industry, economic and market conditions. In particular, the Raptor
          Board considered the significant consolidation and realignment
          occurring in the industry and its view that Raptor must grow rapidly
          or merge with another company in order to compete successfully in the
          information security market.
 
   (viii) The financial terms of the Merger, including the proposed
          structure as a tax-free reorganization, and the Conversion Ratio.
 
   (ix)   The financial presentation rendered to the Raptor Board on November
          24, 1997 and the opinion of Montgomery rendered to the Raptor Board at
          its November 28, 1997 meeting to the effect that as of the date of
          such opinion and based upon and subject to certain matters stated
          therein, the Conversion Ratio was fair, from a financial point of
          view, to the holders of Raptor Common Stock. See Annex C.
          
   (x)    The provisions contained in the Merger Agreement that permit the
          Raptor Board to continue to receive unsolicited inquiries and
          proposals regarding other potential transactions, to give information
          to third parties that make, or express a bona fide intention to make,
          such a proposal and to terminate the Merger Agreement upon payment to
          AXENT of an $8,850,316 termination fee if the Raptor Board determines
          in good faith, after receiving advice of Raptor's legal counsel, that
          such action is necessary in order for the Raptor Board to comply with
          its fiduciary duties. See "The Merger Agreement--Termination." The
          Raptor Board believed that the termination fee was within the range of
          fees payable in comparable transactions and that the fee would not, in
          and of itself, preclude alternative proposals.
 
   (xi)   The possibility that the transaction will be accretive assuming the
          realization of likely operating and financial synergies which may
          result from the Merger.
 
   (xii)  The expectation that the Merger would be accounted for under the
          pooling-of-interests method of accounting.
 
  The Raptor Board also considered the following potentially negative factors
in its deliberations concerning the Merger:
 
   (i)    The various conditions to AXENT's obligations to consummate the
          Merger.
 
   (ii)   The fact that the Conversion Ratio is fixed and not subject to
          adjustment, and, thus, a decrease in the trading price of AXENT
          Common Stock prior to the Effective Time will reduce the
 
                                      40
<PAGE>
 
          consideration to be paid to the holders of the Raptor Common Stock in
          the Merger; and the fact that Raptor does not have the right to
          terminate, or "walk away" from the Merger, in connection with a
          decrease in the trading price of the AXENT Common Stock prior to the
          Effective Time.
 
   (iii)  The risks associated with having the deal value being expressed as a
          set number of shares of AXENT Common Stock, regardless of the value
          thereof at the Effective Time of the proposed Merger.
 
   (iv)   The risk that the trading price of AXENT Common Stock might be
          adversely affected by the announcement of the Merger.
 
   (v)    The charges expected to be incurred in connection with the Merger,
          including costs of integrating the business and transaction expenses
          arising from the Merger.
 
   (vi)   The risk that the Merger would not be consummated following the
          public announcement thereof.
 
   (vii)  The risks of Raptor suffering employee attrition and of failing to
          attract key personnel due to uncertainties associated with the
          pending Merger.
 
   (viii) The potential disruption of Raptor's business that might result
          from employee uncertainty and lack of focus following announcement
          of the Merger and during the integration of the operations of AXENT
          and Raptor.
 
   (ix)   The risk that, despite the intentions and the efforts of the parties
          to support their respective products, the announcement of the Merger
          could result in decisions by customers to defer purchases of products
          of AXENT or Raptor.
 
   (x)    The other risks described under "Risk Factors."
 
  The Raptor Board was aware of the potential benefits to the members of
Raptor's management and the Raptor Board discussed below in "--Interests of
Certain Persons in the Merger," including the provisions of the Merger
Agreement affording indemnification and directors' insurance to the directors
of Raptor for actions and omissions of such persons occurring prior to the
Effective Time. Although these provisions were considered by the Raptor Board,
these factors did not affect the Raptor Board's evaluation or recommendation of
the transaction because such provisions are customary in an agreement relating
to business combinations. Other potential benefits were determined to be of a
nature that would not affect the ability of the members of the Raptor Board to
discharge their duties.
 
  In evaluating the Merger, the Raptor Board also assigned importance to the
fact that three of its current directors would become directors of AXENT.
 
  In the opinion of the Raptor Board, the above factors represent the material
potential adverse consequences that could occur as a result of the Merger. In
considering the Merger and the transactions related thereto, the Raptor Board
considered the impact of these factors on Raptor's existing stockholders. In
the opinion of the Raptor Board, however, these potentially negative factors
were outweighed by the potential positive factors considered by the Raptor
Board which are described above. Accordingly, the Raptor Board voted to approve
the Merger Agreement and the transactions related thereto.
 
  In view of the wide variety of factors considered in connection with its
evaluation of the Merger, the Raptor Board did not find it practicable to, and
did not, quantify or otherwise attempt to assign relative weights to the
specific factors considered in reaching its determination.
 
OPINION OF AXENT'S FINANCIAL ADVISOR
 
  AXENT engaged Broadview to act as its financial advisor and requested that
Broadview render an opinion regarding the fairness, from a financial point of
view, to AXENT's stockholders, of the consideration to be paid by AXENT's
stockholders in the Merger. At the meeting of the AXENT Board on Sunday,
November 30, 1997, Broadview rendered its written opinion (the "Broadview
Opinion") that, as of November 30, 1997, based upon
 
                                       41
<PAGE>
 
and subject to the various factors and assumptions set forth in the Broadview
Opinion, the Conversion Ratio was fair, from a financial point of view, to the
AXENT stockholders. The Conversion Ratio was determined pursuant to
negotiations between AXENT and Raptor and not pursuant to recommendations of
Broadview.
 
  The full text of the Broadview Opinion, which sets forth assumptions made,
matters considered, and limitations on the review undertaken, is attached as
Annex B to this Prospectus/Joint Proxy Statement. AXENT stockholders are urged
to read the Broadview Opinion carefully in its entirety. The Broadview Opinion
addresses only the fairness of the Conversion Ratio from a financial point of
view and does not constitute a recommendation to any stockholder of AXENT as
to how such stockholder should vote at the Meeting. Broadview has advised the
AXENT Board expressly in the Broadview Opinion that Broadview does not believe
that any person (including a stockholder of AXENT) other than the AXENT Board
has the legal right to rely upon its opinion to support any claims against
Broadview arising under applicable state law and that, should any such claims
be brought against Broadview by any such person, this assertion will be raised
as a defense. Should a claim arise, the availability of such a defense would
be resolved by a court of competent jurisdiction. Resolution of the question
of the availability of such a defense, however, will have no effect on the
rights and responsibilities of the AXENT Board under applicable state law. Nor
would the availability of such a state-law defense to Broadview have any
effect on the rights and responsibilities of either Broadview or the AXENT
Board under the federal securities laws. In addition, Broadview will receive a
fee from AXENT contingent upon successful conclusion of the Merger. The
summary of the Broadview Opinion set forth in this Prospectus/Joint Proxy
Statement is qualified in its entirety by reference to the full text of such
opinion.
 
  In rendering its opinion, Broadview, among other actions: (i) reviewed the
terms of the Merger Agreement and the associated exhibits thereto in the form
of the draft dated November 26, 1997 (the "Agreement"), which AXENT management
represented and Broadview subsequently confirmed, contained no material
differences from the definitive Merger Agreement for purposes of the Broadview
Opinion; (ii) reviewed Raptor's annual report and Form 10-K for the fiscal
year ended December 31, 1996 which included results for the fiscal years ended
December 31, 1995 and 1996, including the audited financial statements
included therein, and Raptor's Form 10-Q for the nine months ended September
30, 1997, including the unaudited financial statements included therein; (iii)
reviewed certain internal financial and operating information, including
certain projections, relating to Raptor prepared by Raptor management; (iv)
participated in discussions with Raptor management concerning the operations,
business strategy, financial performance and prospects for Raptor; (v)
reviewed the recent reported closing prices and trading activity for Raptor
Common Stock; (vi) compared certain aspects of the financial performance of
Raptor with public companies deemed comparable; (vii) analyzed available
information, both public and private, concerning other mergers and
acquisitions Broadview believed to be comparable in whole or in part to the
Merger; (viii) reviewed AXENT's annual report and Form 10-K for the fiscal
year ended December 31, 1996 which included results for the fiscal years ended
December 31, 1995 and 1996, including the audited financial statements
included therein, and AXENT's Form 10-Q for the nine months ended September
30, 1997, including the unaudited financial statements included therein; (ix)
participated in discussions with AXENT management concerning the operations,
business strategy, financial performance and prospects for AXENT; (x) reviewed
the recent reported closing prices and trading activity for AXENT Common
Stock; (xi) discussed with AXENT management its view of the strategic
rationale for the Merger; (xii) compared certain aspects of the financial
performance of AXENT with public companies deemed comparable; (xiii)
considered the total number of shares of AXENT Common Stock outstanding and
the average weekly trading volume of AXENT Common Stock; (xiv) reviewed recent
equity analyst reports covering AXENT and Raptor; (xv) analyzed the
anticipated effect of the Merger on the future financial performance of the
consolidated entity; (xvi) assisted in negotiations and discussions related to
the Merger among AXENT, Raptor and their financial and legal advisors; and
(xvii) conducted other financial studies, analyses and investigations as
deemed appropriate for purposes of the Broadview Opinion.
 
  In rendering the Broadview Opinion, Broadview relied, without independent
verification, on the accuracy and completeness of all the financial and other
information (including without limitation the representations and warranties
contained in the Agreement) that was publicly available or furnished by AXENT,
Raptor or Raptor's
 
                                      42
<PAGE>
 
financial advisor. Broadview assumed that those projections prepared and
provided by Raptor were reasonably prepared and reflected the best available
estimates and good faith judgments of the management of Raptor as to the
future performance of Raptor. Broadview did not make or obtain an independent
appraisal or valuation of any of Raptor's assets. With regard to any analyses
relating to valuations of comparable public companies, the share prices used
were for the close of trading on November 28, 1997, the last trading day
before the AXENT Board met to give final consideration to the proposed Merger.
 
  The following is a summary explanation of the various sources of information
and valuation methodologies employed by Broadview in conjunction with
rendering the Broadview Opinion regarding the proposed Merger.
 
  Public Company Comparables Analysis. Total Market Capitalization/Revenue
("TMC/R") and Price/Earnings ("P/E") multiples indicate the value public
markets place on companies in a particular market segment. Several companies
are comparable to Raptor based on revenue size, products offered, business
model, management structure and market position. Broadview reviewed eleven
public company comparables in the security software market from a financial
point of view including each company's: Trailing Twelve Month ("TTM") Revenue;
Last Quarter Annualized ("LQA") Revenue; TTM Revenue Growth; TTM EBIT; TTM
Pretax Income; TTM Net Income; TTM EBIT Margin; TTM Pretax Margin; TTM Net
Margin; 5-year EPS Compound Annual Growth Rate ("CAGR"); Equity Market
Capitalization; TTM P/E ratio; Price/Forward 1997 Calendar EPS ratio ("Forward
P/E 1997"); Price/Forward 1998 Calendar EPS ratio ("Forward P/E 1998"); TMC/R
ratio; and TMC/LQA Revenue ratio. The public company comparables were selected
from the Broadview Barometer, a proprietary database of publicly-traded
Information Technology ("IT") companies maintained by Broadview Associates and
broken down by industry segment. In alphabetical order, the public company
comparables were: AXENT Technologies, Inc., Check Point Software Technologies
Ltd., CyberGuard Corporation, Cylink Corp., Dr. Solomon's Group PLC, McAfee
Associates, Inc., Memco Software Ltd., Secure Computing Corp., Security
Dynamics, Inc., Trusted Information Systems, Inc., and V-ONE Corp. These
comparables have a TTM P/E ratio range of 29.7 to 65.9 with a median of 52.8;
Forward P/E 1997 ratio range of 26.8 to 59.6 with a median of 45.1; Forward
P/E 1998 ratio range of 15.8 to 36.4 with a median of 31.1; TMC/R ratio range
of 2.5 to 25.0 with a median of 6.4; and TMC/LQA Revenue ratio range of 2.2 to
18.1 with a median of 5.7.
 
  The per share valuation implied by the median TTM P/E multiple is $16.78.
The per share valuation implied by the median Forward P/E 1997 multiple is
$14.90. The per share valuation implied by the median Forward P/E 1998
multiple is $14.94. The per share valuation implied by the median TMC/R
multiple is $13.94. The per share valuation implied by the median TMC/LQA
Revenue multiple is $14.47.
 
  Evaluation of AXENT Equity. Broadview compared the ranges and medians of the
same public company comparables as were comparable to Raptor, except for the
removal of AXENT and addition of Raptor as a comparable, with the multiples
implied by AXENT's November 28, 1997 share price of $20.75, and its current
and projected performance.
 
  Transaction Comparables Analysis. Valuation statistics from transaction
comparables indicate the Price/Revenue ("P/R") multiples acquirers have paid
for comparable companies in a particular market segment. Broadview reviewed
nine comparable merger and acquisition ("M&A") transactions from 1996 through
the present with consideration over $15 million which involve sellers sharing
many characteristics with Raptor including products offered and business
model. Transactions were selected from Broadview's proprietary database of
published and confidential M&A transactions in the IT industry. These
transactions represent nine private sellers in the security segment of the
software market. In order of descending P/R multiple, the transactions used
are the acquisition of: (i) Border Network Technologies, Inc. by Secure
Computing Corp.; (ii) Enigma Logic, Inc. by Secure Computing Corp.; (iii) RSA
Data Security, Inc. by Security Dynamics Technologies, Inc.; (iv) Algorithmic
Research by Cylink Corp.; (v) Datawatch Corp. (two products and anti-virus
technology) by Dr. Solomon's Group PLC; and (vi) Jade KK by McAfee Associates,
Inc. Additionally Broadview considered three transactions with respect to
which Broadview has information that is not publicly available. The P/R
multiples of the nine transactions range from 2.07 to 34.22 with a median of
11.52.
 
                                      43
<PAGE>
 
  The per share valuation implied by the median P/R multiple of all nine
transaction comparables is $22.52.
 
  Transaction Premiums Paid Analysis. Premiums paid in comparable public
seller transactions indicate the amount of consideration acquirers are willing
to pay above the seller's equity market capitalization. In this analysis, the
value of consideration paid in transactions involving stock is computed using
the buyer's stock price immediately prior to announcement, while the seller's
equity market capitalization is measured one day prior and thirty days prior
to announcement. Broadview reviewed two sets of transactions for calculating
premiums paid. The first set includes 35 comparable M&A transactions involving
software vendors from January 1, 1995 to the present with total consideration
greater than $50 million and less than $500 million. The second set includes
nine comparable M&A transactions involving Information Technology "Mergers of
Equals" transactions since January 1, 1995. Transactions were selected from
Broadview's proprietary database of published and confidential M&A
transactions in the IT industry. In order of descending premium paid 30 days
prior to announce date, the software transactions used were the acquisition
of: (i) High Level Design Systems Inc. by Cadence Design Systems Inc.; (ii)
GMIS Inc. by HBO & Company; (iii) CyCare Systems, Inc. by HBO & Company; (iv)
Softdesk Inc. by Autodesk Inc.; (v) National Health Enhancement Systems, Inc.
by HBO & Company (pending); (vi) Triad Systems Corp. by Cooperative Computing,
Inc.; (vii) Interactive Group by Dataworks Corp.; (viii) TGV Software, Inc. by
Cisco Systems, Inc.; (ix) Open Environment Corp. by Borland International,
Inc.; (x) Alias Research, Inc. by Silicon Graphics, Inc.; (xi) Hogan Systems,
Inc. by The Continuum Company, Inc.; (xii) Aurum Software, Inc. by Baan
International BV; (xiii) Datalogix International, Inc. by Oracle Corp.; (xiv)
Integrated Silicon Systems, Inc. by ArcSys, Inc.; (xv) OpenVision
Technologies, Inc. by VERITAS Software Corp.; (xvi) Trinzic Corp. by Platinum
Technology, Inc.; (xvii) Delrina Corp. by Symantec Corp.; (xviii) SQA Inc. by
Rational Software Corp.; (xix) Amisys Managed Care Systems, Inc. by HBO &
Company; (xx) Frame Technology Corp. by Adobe Systems, Inc.; (xxi) Saber
Software Corp. by McAfee Associates, Inc.; (xxii) Clinicom, Inc. by HBO &
Company; (xxiii) Viewlogic Systems, Inc. by Synopsys, Inc. (pending); (xxiv)
Epic Design Technology Inc. by Synopsys Inc.; (xxv) C.I.S. Technologies, Inc.
by National Data Corp.; (xxvi) Wavefront Technologies, Inc. by Silicon
Graphics, Inc.; (xxvii) Microtec Research, Inc. by Mentor Graphics Corp.;
(xxviii) HPR, Inc. by HBO & Company (pending); (xxix) PHAMIS Inc. by IDX
Systems Corp.; (xxx) Cooper & Chyan Technology, Inc. by Cadence Design Systems
Inc.; (xxxi) Infinity Financial Technology, Inc. by Sungard Data Systems, Inc.
(pending); (xxxii) Unison Software, Inc. by IBM Corp. (Tivoli Systems)
(pending); (xxxiii) Enterprise Systems, Inc. by HBO & Company; (xxxiv) Meta-
Software, Inc. by Avant! Corp.; and (xxxv) Fractal Design Corp. by MetaTools
Inc.
 
  In order of descending premium paid 30 days prior to announce date, the
Information Technology "Mergers of Equals" transactions used were the
acquisition of: (i) First Financial Management Corp. by First Data Corp.; (ii)
Pure Atria Corp. by Rational Software Corp.; (iii) Boston Technology, Inc. by
Comverse Technology, Inc.; (iv) Atria Software, Inc. by Pure Software, Inc.;
(v) Colonial Data Technologies Corp. by US Order, Inc.; (vi) US Robotics Corp.
by 3COM Corp.; (vii) CompuRAD, Inc. by Lumisys, Inc.; (viii) Fractal Design
Corp. by MetaTools, Inc.; and (ix) Individual, Inc. by Desktop Data, Inc.
 
  Based upon Broadview's analysis of premiums paid in comparable software
transactions, Broadview found that premiums/(discounts) paid to sellers'
equity market capitalizations (using the buyer's share price on the day prior
to the announcement date of the transaction to calculate consideration in
stock transactions) 30 days prior to announce date ranged from (2.3%) to
138.5% with a median of 44.3%. The premiums/(discounts) paid to each seller's
equity market capitalization one day prior to announce date ranged from (8.8%)
to 68.2% with a median of 25.5%.
 
  Based upon Broadview's analysis of premiums paid in comparable "Mergers of
Equals" transactions, Broadview found that premiums/(discounts) paid to
sellers' equity market capitalizations 30 days prior to announce date ranged
from (9.1%) to 21.5% with a median of 7.7%. The premiums/(discounts) paid to
each seller's equity market capitalization one day prior to announce date
ranged from (0.3%) to 38.3% with a median of 11.9%.
 
                                      44
<PAGE>
 
  In the comparable software transactions, the per share valuation implied by
the median premium paid 30 days prior to announce date is $19.85. The per
share valuation implied by the median premium paid one day prior to announce
date is $19.77.
 
  In the "Mergers of Equals" transactions, the per share valuation implied by
the median premium paid 30 days prior to announce date is $14.81. The per
share valuation implied by the median premium paid one day prior to announce
date is $17.62.
 
  Stock Performance Analysis. For comparative purposes, Broadview examined the
weekly historical volume and trading prices for both Raptor and AXENT Common
Stock. Broadview examined the following: (i) AXENT and Raptor actual share
prices and trading volumes from November 22, 1996 to November 28, 1997; (ii)
AXENT, Raptor and the set of Public Company Comparables Indexed share prices
from November 22, 1996 to November 28, 1997; and (iii) the relative ratio of
Raptor to AXENT actual share prices from November 22, 1996 to November 28,
1997.
 
  Conversion Ratio Analysis. An analysis of a range of Conversion Ratios
calculates the implied purchase price of Raptor Common Stock. A Conversion
Ratio range of 0.7500 to 0.9000 implies a premium/(discount) over Raptor's
actual price one day before announcement of the transaction that ranges from
(1.2%) to 18.6%. A Conversion Ratio range of 0.7500 to 0.9000 implies a
premium over Raptor's 20 trading day average price ranges from 11.6% to 33.9%.
A Conversion Ratio of 0.8000 implies a premium over Raptor's actual price one
day before announcement of the transaction of 5.4%. A Conversion Ratio range
of 0.8000 implies a premium over Raptor's 20 trading day average price of
19.0%.
 
  Relative Contribution Analysis. A relative contribution analysis measures
each of the merging companies' contributions to items such as revenue and
operating income on a percentage basis. Broadview examined the actual relative
contributions during the TTM ended September 30, 1997, Projected Calendar 1997
and Projected Calendar 1998, based upon consensus analyst estimates for each
of the two companies for the following income statement items: Revenue,
Operating Income, Pretax Income, Pretax Income excluding Royalties, Net
Income, and Net Income excluding Royalties (all of which exclude discontinued
operations and non-recurring charges).
 
  Raptor's relative contribution for Revenue for the TTM ended September 30,
1997, Projected Calendar 1997 and Projected Calendar 1998 is 41.8%, 40.7% and
40.3%, respectively. Raptor's relative contribution for Operating Income for
the TTM ended September 30, 1997, Projected Calendar 1997 and Projected
Calendar 1998 is 50.6%, 42.8% and 41.5%, respectively. Raptor's relative
contribution for Pretax Income for the TTM ended September 30, 1997, Projected
Calendar 1997 and Projected Calendar 1998 is 43.6%, 41.1% and 42.8%,
respectively. Raptor's relative contribution for Pretax Income ex-Royalties
for the TTM ended September 30, 1997, Projected Calendar 1997 and Projected
Calendar 1998 is 55.3%, 48.6% and 45.2%, respectively. Raptor's relative
contribution for Net Income for the TTM ended September 30, 1997, Projected
Calendar 1997 and Projected Calendar 1998 is 47.3%, 42.9% and 44.2%,
respectively. Raptor's relative contribution for Net Income ex-Royalties for
the TTM ended September 30, 1997, Projected Calendar 1997 and Projected
Calendar 1998 is 59.0%, 50.4% and 46.5%, respectively.
 
  Relative Ownership Analysis. A relative ownership analysis measures each of
the merging companies' relative equity ownership and relative entity values
(net of cash) at various Conversion Ratios. Broadview examined the relative
equity ownership and relative entity value at Conversion Ratios ranging from
0.6710 through 0.8894. At a Conversion Ratio of 0.6710, the implied equity
ownership is 57.0% for AXENT and 43.0% for Raptor, while the implied entity
value is 60.7% for AXENT and 39.3% for Raptor. At a Conversion Ratio of
0.8000, the implied equity ownership is 52.6% for AXENT and 47.4% for Raptor,
while the implied entity value is 55.2% for AXENT and 44.8% for Raptor. At a
Conversion Ratio of 0.8894, the implied equity ownership is 50.0% for AXENT
and 50.0% for Raptor while the implied entity value is 52.0% for AXENT and
48.0% for Raptor.
 
                                      45

  Pro Forma Pooling Model Analysis. A pro forma merger analysis calculates the
EPS accretion/(dilution) of the pro forma combined entity taking into
consideration various financial affects which will result from a consummation
of the Merger. This analysis relies upon certain financial and operating
assumptions provided by equity research analysts and on publicly available
data about Raptor and AXENT. Based on consensus analysts' forecasts for each
of the two companies and Broadview's assumption of approximately $3.1 million
of pretax contribution derived from cost savings, the pro forma pooling
analysis indicates EPS accretion/(dilution) without acquisition expenses for
the fiscal year ending December 31, 1997 and 1998 of (8.5%) and 2.3%,
respectively.
 
  Present Value of Projected Share Price Analysis. Broadview calculated the
present value of the potential future price of shares of AXENT Common Stock on
a standalone basis using consensus analyst estimates for the fiscal year
ending December 31, 1998 discounted to today at discount rates from 15% to
30%. The potential future share price based on December 31, 1998 financial
results is calculated based upon an estimated calendar 1998 EPS (as estimated
using analyst consensus estimates) and assumes TTM price-earnings multiples of
between 40.0x and 60.0x, in line with comparable public company multiples.
Based on this analysis, Broadview calculated present values of potential
future share prices ranging from $19.96 to $34.58. In addition, Broadview
performed an analysis of the pro forma present value per AXENT share assuming
the consummation of the Merger. This analysis applied the same range of
multiples of earnings per share to estimated 1998 EPS for the combined entity
(based on consensus analyst estimates) and discounted the future share prices
to today using the same range of discount rates as for the standalone
analysis. Based on this analysis, Broadview estimated present values of future
share prices ranging from $20.42 to $35.37.
 
  Consideration of the Discounted Cash Flow Valuation Methodology. While
discounted cash flow is a commonly used valuation methodology, Broadview did
not employ such an analysis for the purposes of this opinion. Discounted cash
flow analysis is most appropriate for companies which exhibit relatively
steady or somewhat predictable streams of future cash flow. For a rapidly
growing company such as Raptor, a preponderance of the value in a valuation
based on discounted cash flow will be in the terminal value of the entity,
which is extremely sensitive to assumptions about the sustainable long-term
growth rate of the company. Given the uncertainty in estimating a sustainable
long-term growth rate for AXENT, Broadview considered a discounted cash flow
analysis inappropriate for valuing Raptor.
 
  The AXENT Board selected Broadview as its financial advisor on the basis of
Broadview's reputation and experience in the Information Technology sector and
the computer software industry in particular, as well as Broadview's
historical relationship with AXENT. Pursuant to the terms of an engagement
letter between AXENT and Broadview, Broadview was due a fee upon delivery of
the Broadview opinion and additional fees payable upon completion of the
Merger, based upon the consideration to be paid by AXENT pursuant to the
Merger. Broadview will be reimbursed by AXENT for certain of its expenses
incurred in connection with its engagement. The terms of the fee arrangement
with Broadview, which AXENT and Broadview believe are customary in
transactions of this nature, were negotiated at arms' length between AXENT and
Broadview, and the AXENT Board was aware of the nature of the fee arrangement,
including the fact that a significant portion of the fee payable to Broadview
is contingent upon completion of the Merger.
 
  The above summary of the presentations by Broadview to the AXENT Board does
not purport to be a complete description of such presentations or of all the
advice rendered by Broadview. Broadview believes that its analyses and the
summary set forth above must be considered as a whole and that selecting
portions of its analyses, without considering all analyses, could create an
incomplete view of the process underlying the analyses set forth in
Broadview's presentations to the AXENT Board and in the Broadview Opinion. In
rendering the Broadview Opinion, Broadview assumed that neither AXENT nor
Raptor was involved in any material transaction, including financings,
recapitalizations, mergers, acquisitions and dispositions, other than the
Merger and those activities undertaken in the ordinary course of conducting
their respective businesses. The Broadview Opinion is necessarily based upon
market, economic, financial and other conditions as they existed and could be
evaluated as of the date of the Broadview Opinion. The Broadview Opinion
expresses no opinion as to the price at which AXENT Common Stock will trade
subsequent to the Effective Time. In performing its analyses,
 
                                      46
<PAGE>
 
Broadview made numerous assumptions with respect to software industry
performance and general economic conditions, many of which are beyond the
control of Raptor or AXENT. The analyses performed by Broadview are not
necessarily indicative of actual values or actual future results, which may be
significantly more or less favorable than suggested by such analyses.
 
OPINION OF RAPTOR'S FINANCIAL ADVISOR
 
  Raptor engaged Montgomery to act as its exclusive financial advisor in
connection with the evaluation of an offer by AXENT to acquire Raptor on the
terms and conditions set forth in the Merger Agreement. Montgomery is a
nationally recognized firm and, as part of its investment banking activities,
is regularly engaged in the valuation of businesses and their securities in
connection with merger transactions and other types of acquisitions,
negotiated underwritings, secondary distributions of listed and unlisted
securities, private placements and valuations for corporate and other
purposes. Raptor selected Montgomery as its financial advisor on the basis of
its experience and expertise in transactions similar to the Merger and its
reputation as an investment banker in transactions involving technology
companies.
 
  At the November 28, 1997 meeting of the Raptor Board, Montgomery delivered
its opinion that the consideration to be paid by AXENT to the stockholders of
Raptor in the Merger is fair to such stockholders from a financial point of
view, as of the date of such opinion. The amount of such consideration was
determined pursuant to negotiations between Raptor and AXENT with advice from
Montgomery and Broadview, respectively. No limitations were imposed by Raptor
on Montgomery with respect to the investigations made or procedures followed
in rendering its opinion. The full text of Montgomery's written opinion to the
Raptor Board, which sets forth the assumptions made, matters considered and
limitations of review by Montgomery, is attached hereto as Annex C, and is
incorporated herein by reference and should be read carefully in its entirety.
The following summary of Montgomery's opinion is qualified in its entirety by
reference to the full text of the opinion, attached as Annex C.
 
  Montgomery has informed Raptor that in arriving at its opinion it: (i)
reviewed certain publicly available financial and other data with respect to
Raptor and AXENT, and certain other relevant financial and operating data
relating to Raptor and AXENT made available to Montgomery from published
sources and from internal records of Raptor and AXENT; (ii) reviewed the
financial terms and conditions of the Merger Agreement; (iii) reviewed certain
publicly available information concerning the trading of, and the trading
market for, Raptor Common Stock and AXENT Common Stock; (iv) compared Raptor
and AXENT from a financial point of view with certain other companies in the
software industry that Montgomery deemed to be relevant; (v) considered the
financial terms, to the extent publicly available, of selected recent business
combinations of companies in the software industry that Montgomery deemed to
be comparable in whole or in part, to the Merger; (vi) reviewed the premiums
paid in selected recent merger of equals combinations which Montgomery deemed
to be comparable in whole or in part, to the Merger; (vii) reviewed the
financial contribution each company is making to the combined company and
compared that contribution to the percentage ownership each company's
stockholders will hold in the combined company after the Merger closes; (viii)
reviewed and discussed with representatives of the managements of Raptor and
AXENT certain information of a business and financial nature regarding Raptor
and AXENT furnished to Montgomery by Raptor and AXENT, including financial
forecasts and related assumptions of Raptor and AXENT; and (ix) performed such
other analyses and examinations as Montgomery deemed appropriate.
 
  In connection with its review, Montgomery did not independently verify the
foregoing information and relied on its being accurate and complete in all
material respects. With respect to the financial forecasts for Raptor and
AXENT provided to Montgomery by their respective managements, Montgomery
assumed for purposes of its opinion that the forecasts were reasonably
prepared on bases reflecting the best available estimates and judgments of
their respective managements at the time of preparation as to the future
financial performance of Raptor and AXENT and that they provided a reasonable
basis upon which Montgomery could form its
 
                                      47

opinion. Montgomery also assumed that there had been no material changes in
the assets, financial condition, results of operations, business or prospects
since the respective dates of their last financial statements made available
to it. In addition, Montgomery did not assume responsibility for making an
independent evaluation, appraisal or physical inspection of any of the assets
or liabilities (contingent or otherwise) of Raptor and AXENT, nor was it
furnished with any such appraisals. Raptor informed Montgomery, and Montgomery
assumed, that the Merger will be recorded as a pooling-of-interests under
generally accepted accounting principles and that it will be a tax-free
reorganization. Montgomery also assumed the Merger will be consummated in
accordance with the terms described in the Merger Agreement, without any
further amendments thereto, and without waiver by Raptor of any of the
conditions to its obligations thereunder.
 
  Set forth below is a brief summary of selected analyses presented by
Montgomery to the Raptor Board on November 24, 1997 in connection with its
presentation on such date and its opinion of November 28, 1997.
 
  Premium Paid Analysis. Montgomery examined the consideration paid in a
number of acquisitions of publicly-traded technology companies. The
transactions reviewed for this analysis included mergers of equals
transactions completed or announced since January 1990 in which the parties
intended the transaction to be treated as a pooling-of-interests under
generally accepted accounting principles. The transactions involving
technology companies reviewed by Montgomery in this analysis were the
acquisitions of (i) Individual, Inc. by Desktop Data, Inc.; (ii) Boston
Technology, Inc. by Comverse Technology, Inc.; (iii) US Robotics Corp. by 3Com
Corporation; (iv) Atria Software, Inc. by Pure Software, Inc.; (v) Integrated
Silicon Systems, Inc. by Avant! Corp.; (vi) NYNEX Corporation by Bell Atlantic
Corporation; (vii) First Financial Management Corp. by First Data Corp.; and
(viii) SynOptics Communications, Inc. by Wellfleet Communications, Inc.
Montgomery compared, among other matters, the range of percentage premiums
represented by the consideration paid in such mergers over the market price
for the target company's stock at 30 days, one week and on the last trading
day, prior to announcement of the transaction. This analysis yielded a mean
average of premiums (excluding the high and low premiums) of approximately 9%
over the trading price for the 30-day time period, 14% for the one week time
period, and 6% for the last trading day prior to announcement. Montgomery then
applied such premiums to the closing prices of Raptor's Common Stock on
October 17, 1997 (thirty days prior to the announcement of the transaction),
November 21, 1997 (one week prior to the announcement) and November 28, 1997
(the last trading day prior to the announcement of the transaction), resulting
in a range of values from $15 to $17 per share of Raptor Common Stock.
 
  Comparable Merger and Acquisition Transaction Analysis. Montgomery reviewed
the consideration paid in several acquisition transactions involving network
security software and other software companies. Montgomery analyzed the
consideration paid in such transactions as a multiple of the target company's
revenues for the last 12 months reported prior to announcement of the
transaction ("LTM revenues"). The transactions reviewed by Montgomery for
purposes of this analysis included the acquisitions of (i) Lotus Development
Corp. by IBM Corp.; (ii) Cheyenne Software by Computer Associates, Inc.; (iii)
Powersoft Corp. by Sybase Inc.; (iv) Tivoli Systems Inc by IBM Corp.; (v)
Frame Technology Corp. by Adobe Systems, Inc.; (vi) OpenVision Technologies,
Inc. by VERITAS Software Corp.; (vii) Aurum Software, Inc. by Baan
International BV; (viii) Border Network Technologies, Inc. by Secure Computing
Corporation; (ix) RSA Data Security Inc. by Security Dynamics Technologies,
Inc.; (x) Meta Software, Inc. by Avant! Corp.; (xi) Fractal Design Corp. by
MetaTools, Inc.; (xii) Wavefront Technologies, Inc. by Silicon Graphics, Inc.;
(xiii) Firefox Communications, Inc. by FTP Software, Inc.; (xiv) Enigma Logic,
Inc. by Secure Computing Corp.; and (xv) AssureNet Pathways Inc. by AXENT
Technologies, Inc. Such analysis yielded a mean average enterprise valuation
of 7x LTM revenues. Montgomery then applied a similar analysis to Raptor and
determined that the consideration to be paid in the Merger represented an
enterprise value of Raptor equal to 8x its LTM revenues.
 
  Comparable Public Company Analysis. Using public and other available
information, Montgomery determined a range of implied equity values for Raptor
based on the multiples of estimated 1998 earnings (normalized for a calendar
year end) at which the common stock of the following selected network security
software companies traded on November 28, 1997: AXENT Technologies, Inc.,
Check Point Software Ltd.,
 
                                      48
<PAGE>
 
Memco Software Ltd., Secure Computing Corporation, Security Dynamics
Technologies, Inc., and Trusted Information Systems, Inc., (the "Comparable
Companies"). Montgomery deemed the relevant range of valuations to be between
28x and 35x estimated 1998 earnings based on the November 28, 1997 stock
prices of the Comparable Companies. Montgomery applied the foregoing multiples
to the applicable estimates for Raptor. This analysis indicated a range of
implied values for Raptor of between $202 million and $257 million, or between
$13 and $17 per share of Raptor Common Stock (after adjustment for debt and
cash and cash equivalents).
 
  Contribution Analysis. Montgomery performed a contribution analysis for
Raptor. This analysis reviewed the projected contribution of Raptor and AXENT
to the total revenues and operating income of the combined company based on
1997 and 1998 forecasts. According to this analysis, Raptor will contribute,
on average, 41% of the revenues and operating income in the combined company,
which would imply a value of $14 per share of Raptor Common Stock and a
Conversion Ratio of 0.69 per share of AXENT Common Stock.
 
  Discounted Cash Flow Analysis. Montgomery performed a discounted cash flow
analysis of Raptor. The analysis aggregated the present value of projected
free cash flow (defined as earnings before interest and taxes, less taxes)
through 2001, and the present value of a terminal value for the year 2001
based on a revenue multiple of 6.9x, applying discount rates of 30%, 32.5% and
35%. After subtracting the current cash of Raptor, such analysis yielded
values per share of Raptor Common Stock ranging from $16.52 to $14.64.
 
  While the foregoing summary describes the analyses and examinations that
Montgomery deemed material to its opinion, it is not a comprehensive
description of all analyses and examinations actually performed. The
preparation of a fairness opinion necessarily is not susceptible to partial
analysis or summary description. Montgomery believes that such analyses and
the summary set forth above must be considered as a whole and that selecting
portions of its analyses and of the factors considered, without considering
all such analyses and factors, would create an incomplete view of the analyses
set forth in its presentation to the Raptor Board. In addition, Montgomery may
have given various analyses more or less weight than other analyses, and may
have deemed various assumptions more or less probable than other assumptions,
so that the ranges of valuations resulting from any particular analysis should
not be taken to be Montgomery's view of the actual value of Raptor, AXENT or
the combined company.
 
  In performing its analyses, Montgomery made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Raptor or AXENT. The
analyses performed by Montgomery are not necessarily indicative of actual
values or actual future results, which may be significantly more or less
favorable than suggested by such analyses. Such analyses were prepared solely
as part of Montgomery's analysis of the fairness of the Merger to the
stockholders of Raptor from a financial point of view and were provided to the
Raptor Board in connection with the delivery of Montgomery's opinion. The
analyses do not purport to be appraisals or to reflect the prices at which a
company might actually be sold or the prices at which any securities may trade
at the present time or at any time in the future. Montgomery used in its
analyses various projections of results of operations prepared by the
managements of Raptor and AXENT and by research analysts of third party
brokerage firms. The projections are based on numerous variables and
assumptions that are inherently unpredictable and must be considered not
certain of occurrence as projected. Accordingly, actual results could vary
significantly from those set forth in such projections.
 
  As described above, Montgomery's opinion and presentation to the Raptor
Board were among the many factors taken into consideration by the Raptor Board
in making its determination to approve, and to recommend that its stockholders
approve, the Merger.
 
  In connection with the Merger, Raptor has agreed to pay Montgomery a fee of
$875,000, $150,000 of which became due upon Montgomery's delivery of its
fairness opinion and the remainder of which will become due upon consummation
of the Merger. Raptor has also agreed to reimburse Montgomery for its
reasonable out-of-
 
                                      49

pocket expenses. Pursuant to a separate Indemnification and Contribution
Agreement, Raptor has agreed to indemnify Montgomery, its affiliates, and
their respective partners, directors, officers, agents, consultants, employees
and controlling persons against certain liabilities, including liabilities
under the federal securities laws.
 
  In the ordinary course of its business, Montgomery actively trades
securities of Raptor and AXENT for its own account and for the accounts of
customers and, accordingly, may at time hold a long or short position in such
securities. Certain partners of Montgomery may also own shares of common stock
of Raptor and AXENT.
 
  The full text of Montgomery's opinion, dated November 28, 1997, which sets
forth the assumptions made, general procedures followed, matters considered
and limitations on the scope of review undertaken by Montgomery in rendering
its opinion, is attached as Annex C to this Prospectus/Joint Proxy Statement
and is incorporated herein by reference. Montgomery's opinion is addressed to
the Board of Directors of Raptor and is directed only to the fairness from a
financial point of view, as of November 28, 1997, of the consideration to be
issued to the stockholders of Raptor in the Merger and does not constitute a
recommendation to any Raptor stockholder as to how such stockholder should
vote with respect to the merger.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  In considering the recommendation of the Raptor Board with respect to the
Merger, the Merger Agreement and the transactions contemplated thereby, the
holders of Raptor Common Stock should be aware that certain members of the
Raptor Board and the management of Raptor have certain interests in, and will
receive benefits from, the Merger that are different from, or in addition to,
the interests of, and benefits to, the holders of Raptor Common Stock
generally. The Raptor Board was aware of these conflicts of interest and
benefits, and considered them, among other matters, in deciding whether to
approve the Merger, the Merger Agreement and the transactions contemplated
thereby.
 
  Pursuant to the terms of the Merger Agreement, AXENT has agreed to take all
action necessary to cause Robert Steinkrauss (Chairman of the Raptor Board),
Shaun McConnon (President, Chief Executive Officer and a director of Raptor)
and Robert Schechter (a director of Raptor), to become members of the AXENT
Board of Directors, subject to the consummation of the Merger.
 
  Pursuant to the Merger Agreement, following consummation of the Merger,
AXENT will, or will cause Raptor to, honor in accordance with their terms, all
employment, severance and similar agreements to which Raptor is a party and
all provisions for vested benefits or other vested amounts earned or accrued.
 
  Director-Level and Above Severance Agreements. In connection with the
Merger, Raptor has entered into Severance Agreements, which become effective
upon the date the Merger is consummated, with (i) Mr. Steinkrauss, (ii) Mr.
McConnon, (iii) Mr. John Ingalls, Chief Financial Officer of Raptor, (iv) Mr.
Jim Charlton, a Senior Vice-President of Raptor, (v) Mr. Alan Kirby, a Senior
Vice-President of Raptor, (vi) Mr. Lance Urbas, a Senior Vice-President of
Raptor, and (vii) certain other director-level and above employees. The
Severance Agreements provide, among other things, that if such employee's
employment is terminated other than for Cause (as defined in the Severance
Agreements), or the employee resigns for Good Reason (as defined in the
Severance Agreements) (each a "Triggering Event"), during a range of periods
that begin on the Effective Time and end as late as two years from the
Effective Time, such employee has a right to receive a lump-sum severance
payment (aggregating approximately $1,000,000 for the persons listed above
assuming no change in current base salary levels, in the following amounts:
six (6) months for director-level employees, nine (9) months for vice-
presidents, one (1) year for the chief executive officer, chief financial
officer and senior vice-presidents, and two (2) years for the chairman of the
Raptor Board, of base salary as then in effect) and continued health and
dental benefits for the same period. Notwithstanding the foregoing, (a) in the
event that the Merger is not consummated prior to February 28, 1997 and a
Triggering Event occurs prior to May 9, 1998, the Severance Agreements provide
such
 
                                      50
<PAGE>
 
employees (other than Messrs. Steinkrauss, McConnon and Ingalls), with the
option to elect to have their employment continue on a part-time basis until
May 9, 1998, at which time they would cease to be employed by Raptor and would
be entitled to receive the excess of their severance payment over the amount
of salary they received from the Triggering Event to May 9, 1998, and (b) Mr.
Ingalls, in the event a Triggering Event occurs prior to September 30, 1998,
has the option to elect to have his employment continue on a part-time basis
until September 30, 1998, at which time he would cease to be employed by
Raptor and would be entitled to receive the excess of his severance payment
over the amount of salary he received from the Triggering Event to September
30, 1998. Assuming that the Merger is consummated and that each person's base
salary (as of December 1, 1997) is unchanged as of the date the Merger is
consummated, upon the happening of a Triggering Event, the severance payments
would be approximately: (1) $220,000 to Mr. Steinkrauss; (2) $220,000 to Mr.
McConnon; (3) $150,000 to Mr. Ingalls; (4) $210,000 to Mr. Charlton; (5)
$150,000 to Mr. Kirby; and (6) $135,000 to Mr. Urbas.
 
  Consulting Agreements. In connection with the Merger, Raptor has entered
into Consulting Agreements, which become effective upon the Effective Time,
with (i) Mr. McConnon pursuant to which he will receive an aggregate of
$550,000 in consideration of certain consulting services that Mr. McConnon
will provide to Raptor, AXENT and/or the Surviving Corporation through
September 30, 1998, in connection with the Merger and the integration of the
respective businesses of Raptor and AXENT; and (ii) Mr. Ingalls pursuant to
which he will receive an aggregate of $190,000 in consideration of certain
consulting services that Mr. Ingalls will provide to Raptor, AXENT and/or the
Surviving Corporation through the later of March 31, 1998 or the date on which
the date on which the Merger is consummated, in connection with the Merger and
the initial integration of the respective businesses of Raptor and AXENT. The
respective Consulting Agreements with Messrs. McConnon and Ingalls provide
that in the event that any portion of the consulting payments outlined above,
when considered together with all other amounts to be received by such person
from Raptor or any successor entity, would constitute an "excess parachute
payment" within the meaning of Section 280G of the Code, then Raptor will make
an additional payment (the "Gross-Up") to such individual to offset the effect
of any excise taxes (and penalties) and any income taxes on the Gross-Up.
 
  Bonus Agreements. In connection with the Merger, Raptor has entered into
Bonus Agreements with Messrs. Charlton, Kirby, Urbas, and certain other
employees of Raptor. Such Bonus Agreements, which become effective upon the
date that the Merger is consummated, provide 29 employees (including Messrs.
Charlton, Kirby and Urbas) of Raptor with bonus payments (aggregating
approximately $1,300,000) based upon combinations of the employee's (i)
contribution to the successful consummation of the Merger, (ii) contribution
to the initial integration of the respective businesses of Raptor and AXENT,
and/or (iii) contribution to the long-term integration of the respective
businesses of Raptor and AXENT. Pursuant to the terms of the Bonus Agreements,
each employee is entitled to receive his or her entire bonus payment unless he
or she voluntarily resigns without Good Reason (as defined in the Bonus
Agreements), in which case he or she would forfeit any bonus not yet earned.
Assuming that the Merger is consummated and the respective employee has not
voluntarily resigned other than for Good Reason, the bonuses to be paid by
Raptor or the Surviving Company would be (1) $300,000 to Mr. Charlton, (2)
$20,000 to Mr. Kirby, and (3) $240,000 to Mr. Urbas.
 
  Raptor Stock Options. As of December 19, 1997, options to purchase a total
of 649,287 shares of Raptor Common Stock were held by certain of Raptor's
executive officers and non-employee members of Raptor's Board, and currently
remain outstanding and not vested and will become fully vested and immediately
exercisable in connection with the Merger. In the event that such individuals
exercise the options to purchase such shares of Raptor Common Stock, the
aggregate value (net of exercise price and assuming a price of $13.20 per
share of Raptor Common Stock (the closing price of the AXENT Common Stock on
December 19, 1997 multiplied by the Conversion Ratio)) for such options would
be $7,069,781; including (a) $2,818,046 for the options of Mr. Steinkrauss,
(b) $2,057,100 for the options of Mr. McConnon, (c) $0 for the options of Mr.
Ingalls, (d) $475,603 for the options of Mr. Charlton, (e) $1,602,996 for the
options of Mr. Kirby, (f) $116,036 for the options of Mr. Urbas, and (g) $0
for the options of each of Messrs. Schechter, Kaiser, Owen and Parizeau (the
non-employee members of the Raptor Board) whose respective options are out-of-
the-money. Additional
 
                                      51
<PAGE>
 
options to purchase shares of Raptor Common Stock have been issued to certain
executive officers of Raptor which will terminate upon consummation of the
Merger.
 
  Raptor Restricted Common Stock. As of December 1, 1997, Messrs. Schechter,
Kaiser, Owen and Parizeau (the non-employee members of the Raptor Board) each
held 6,000 shares of Raptor Restricted Stock, which restrictions on all of
such Raptor Restricted Stock will lapse in connection with the Merger.
Assuming a $13.20 per share price of Raptor Common Stock (the closing price of
AXENT Common Stock on December 19, 1997 multiplied by the Conversion Ratio),
the aggregate value (net of $.50 per share purchase price) to such individuals
would be $304,800; including $76,200 for each of Messrs. Schechter, Kaiser,
Owen, and Parizeau.
 
  Registration Rights. Pursuant to the terms of the Merger Agreement, AXENT
has agreed to file and keep effective for 270 days from the date that AXENT
has publicly released statements of combined financial results covering at
least 30 days of operations, a shelf registration statement on Form S-3
covering the shares of AXENT Common Stock to be held by "affiliates" of Raptor
immediately following the Effective Time which will permit such "affiliates"
to sell their shares without regard to the requirements of Rule 145 in open-
market or similar transactions.
 
  Indemnification. AXENT will indemnify and hold harmless directors, officers,
and agents of Raptor as provided in Raptor's Certificate of Incorporation, By-
Laws or indemnification agreements, in effect on the date of the Merger
Agreement with respect to matters covered thereby occurring through the
Effective Time which provisions shall not be amended, repealed or otherwise
modified for a period of six years so as to adversely affect the rights
thereunder. AXENT will also purchase or assume officers' and directors'
liability insurance with coverage on substantially similar terms as currently
provided by Raptor for a period of six years following the Effective Time.
 
ACCOUNTING TREATMENT
 
  The Merger is intended to qualify as a pooling-of-interests for accounting
and financial reporting purposes under GAAP. Under this method of accounting,
as of the Effective Time, the assets and liabilities of Raptor would be
combined with those of AXENT at their recorded book values and the
stockholders' equity accounts of AXENT and Raptor would also be combined.
Consummation of the Merger is conditioned on, among other things, (i) receipt
by AXENT and Raptor of letters from AXENT's and Raptor's independent
accountants concurring with management's conclusion that no conditions exist
that would preclude accounting for the Merger as a pooling-of-interests under
GAAP, and (ii) receipt of Affiliate Agreements by both AXENT and Raptor from
certain stockholders, restricting sales of AXENT Common Stock following the
Merger. See "Unaudited Pro Forma Condensed Combined Financial Statements of
AXENT and Raptor."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following discussion addresses the material federal income tax
considerations of the Merger that are generally applicable to holders of
Raptor Common Stock. This discussion is based on the interpretation of the
Code, applicable Treasury Regulations, judicial authority and administrative
rulings and practice, all as of the date hereof. Neither AXENT nor Raptor has
requested a ruling from the IRS as to the tax consequences of the Merger. The
IRS is not precluded from sustaining a position contrary to the conclusions
set forth herein. In addition, there can be no assurance that future
legislative, judicial or administrative changes or interpretations will not
adversely affect the accuracy of the statements and conclusions set forth
herein. Any such changes or interpretations could be applied retroactively and
could affect the tax consequences of the Merger to AXENT, Raptor and/or their
respective stockholders.
 
  Raptor stockholders should be aware that the following discussion does not
deal with all federal income tax considerations that may be relevant to
particular Raptor stockholders in light of their particular circumstances,
such as stockholders who are dealers in securities, tax-exempt entities, or
persons who are foreign persons or who acquired their Raptor Common Stock
through stock option or stock purchase programs or in other
 
                                      52
<PAGE>
 
compensatory transactions. In addition, the following discussion does not
address the tax consequences of transactions effectuated prior to or after the
Merger (whether or not such transactions are in connection with the Merger),
including without limitation the exercise of options or rights to purchase
Raptor Common Stock in anticipation of the Merger or the assumption by AXENT
of options or rights to acquire Raptor Common Stock. Finally, no foreign,
state or local tax considerations are addressed herein. ACCORDINGLY, RAPTOR
STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC
TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING THE APPLICABLE FEDERAL,
STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE MERGER.
 
  The consummation of the Merger is conditioned upon there being delivered,
prior to the Effective Time, to each of AXENT and Raptor an opinion of its
respective counsel (the "Tax Opinions") to the effect that the Merger will
constitute a "reorganization" within the meaning of Section 368(a) of the
Code. The Tax Opinions will be delivered by Piper & Marbury L.L.P., counsel to
AXENT, and Goodwin, Procter & Hoar LLP, counsel to Raptor, and will be
substantially in the form of the opinions filed as an exhibit to the
Prospectus/Joint Proxy Statement. Accordingly, the material federal income tax
consequences of the Merger will be as follows:
 
    (i) The Merger will constitute a reorganization within the meaning of
  Section 368(a) of the Code;
 
    (ii) No gain or loss will be recognized by AXENT, the Merger Subsidiary
  or Raptor solely as a result of the Merger;
 
    (iii) No gain or loss will be recognized by the holders of Raptor Common
  Stock upon the exchange of Raptor Common Stock solely for shares of AXENT
  Common Stock as a result of the Merger (except to the extent of cash
  received in lieu of a fractional share thereof);
 
    (iv) The tax basis of the shares of AXENT Common Stock received by the
  holders of Raptor Common Stock in the Merger will be equal to the tax basis
  of the shares of Raptor Common Stock exchanged therefor in the Merger;
 
    (v) The holding period for the shares of AXENT Common Stock received by
  the holders of Raptor Common Stock will include the holding period for the
  shares of Raptor Common Stock exchanged therefor in the Merger, provided
  that the shares of Raptor Common Stock are held as capital assets at the
  Effective Time; and
 
    (vi) Cash received by the holders of Raptor Common Stock in lieu of
  fractional shares of AXENT Common Stock will be treated as received as a
  distribution in redemption of such fractional shares, subject to the
  provisions of Section 302 of the Code, as if such fractional shares had
  been issued in the Merger and then redeemed by AXENT.
 
  The Tax Opinions will be based on certain assumptions and representations of
AXENT, Raptor and certain Raptor stockholders and will be subject to certain
limitations and qualifications as noted therein. In particular, the Tax
Opinions will be based, in part, upon representations by AXENT and Raptor
that, to the best of their knowledge, taking into account cash payments in
lieu of fractional shares and any dispositions by Raptor stockholders in
anticipation of the Merger, there is no plan or intention on the part of the
Raptor stockholders to dispose of shares of AXENT Common Stock received in the
Merger that would reduce the aggregate value of the AXENT Common Stock held by
Raptor stockholders to less than 50% of the value of the Raptor Common Stock
as of the effective date of the Merger. In addition, counsel will assume for
purposes of rendering the Tax Opinions that such representations are correct
as if made without such "best knowledge" qualification. Moreover, legal
counsel will receive representations from certain Raptor stockholders that
they are not participating in and are not aware of any such plan or intention.
 
  A successful IRS challenge to the qualification of the Merger as a
reorganization would result in a Raptor stockholder recognizing gain or loss
with respect to each share of Raptor Common Stock surrendered equal to the
difference between the stockholder's basis in such share and the fair market
value, as of the Effective Time,
 
                                      53
<PAGE>
 
of the AXENT Common Stock received in exchange therefor. In such event, a
Raptor stockholder's aggregate basis in the AXENT Common Stock so received
would equal its fair market value, and the stockholder's holding period for
such stock would begin the day after the Merger. In addition, under certain
circumstances Raptor would recognize taxable gain or loss equal to the
difference between (i) the sum of the fair market value of AXENT Shares
received by the Raptor stockholders and the liabilities of Raptor and (ii)
Raptor's tax basis in its assets.
 
  Even if the Merger qualifies as a reorganization, a recipient of shares of
AXENT Common Stock would recognize gain to the extent that such shares were
considered to be received in exchange for services or property (other than
solely Raptor Common Stock). All or a portion of such gain may be taxable as
ordinary income. Gain would also have to be recognized to the extent that a
Raptor stockholder was treated as receiving (directly or indirectly)
consideration other than AXENT Common Stock in exchange for the Raptor Common
Stock.
 
FEDERAL SECURITIES LAW CONSEQUENCES
 
  All shares of AXENT Common Stock received by Raptor stockholders in the
Merger will be freely transferable, except that shares of AXENT Common Stock
received by persons who are deemed to be "affiliates" (as such term is defined
under the Securities Act) of Raptor prior to the date of the Raptor Special
Meeting may be resold by them only in transactions permitted by the resale
provisions of Rule 145 promulgated under the Securities Act or as otherwise
permitted under the Securities Act. Persons who may be deemed to be affiliates
of Raptor generally include individuals or entities that control, are
controlled by, or are under common control with, such party and may include
certain officers and directors of Raptor as well as principal stockholders of
Raptor. The Merger Agreement requires Raptor to cause certain of its
affiliates to execute a written agreement to the effect that such person will
not offer or sell or otherwise dispose of any of the shares of AXENT Common
Stock issued to such person in or pursuant to the Merger in violation of the
Securities Act or the rules and regulations promulgated by the Commission
thereunder. AXENT has agreed to file and keep effective for 270 days from the
date that AXENT has publicly released statements of combined financial results

                             THE MERGER AGREEMENT
 
  The following is a brief summary of certain provisions of the Merger
Agreement, a copy of which is attached as Annex A to this Prospectus/Joint
Proxy Statement and incorporated herein by reference. Although this section
summarizes the material terms of the Merger Agreement, such summary is
qualified in its entirety by reference to the Merger Agreement. Stockholders
of AXENT and Raptor are urged to read the Merger Agreement in its entirety for
a more complete description of the Merger.
 
THE MERGER
 
  The Merger Agreement provides that, following the approval by the AXENT
stockholders of the AXENT Share Proposal and the approval and adoption of the
Merger and the Merger Agreement by the stockholders of Raptor and the
satisfaction or waiver of the other conditions to the Merger, the Merger
Subsidiary will be merged with and into Raptor, with Raptor continuing as the
Surviving Corporation, which will be a wholly-owned subsidiary of AXENT.
 
  If all such conditions to the Merger are satisfied or waived, the Merger
will become effective upon the filing of a duly executed Certificate of Merger
with the Secretary of State of the State of Delaware.
 
CONVERSION OF SECURITIES
 
  As of the Effective Time and by virtue of the Merger and without any action
on the part of AXENT, Raptor or any of Raptor's stockholders, pursuant to the
Merger Agreement, each issued and outstanding share of Raptor Common Stock
(other than shares of Raptor Common Stock owned by AXENT or the Merger
Subsidiary) will be converted into the right to receive 0.80 of a share of
AXENT Common Stock. If any holder of shares of Raptor Common Stock would be
entitled to receive a number of shares of AXENT Common Stock that includes a
fraction, then, in lieu of a fractional share, such holder will be entitled to
receive cash in an amount equal to such fractional part of a share of AXENT
Common Stock multiplied by the average of the closing price of AXENT Common
Stock, as reported on Nasdaq, for the ten (10) trading days immediately
preceding the Effective Time. Each share of Common Stock of the Merger
Subsidiary issued and outstanding immediately prior to the Effective Time
shall be converted into one (1) share of the Surviving Corporation.
 
  Within thirty (30) days after the Effective Time, Boston EquiServe L.P. (the
"Exchange Agent") will mail a notice and transmittal form to each holder of
record of Raptor Common Stock to be used to surrender and exchange
certificates evidencing shares of Raptor Common Stock for certificates
evidencing the shares of AXENT Common Stock to which such holder has become
entitled. After receipt of such transmittal forms, each holder of certificates
formerly representing Raptor Common Stock will be able to surrender such
certificates to the Exchange Agent, and each such holder will receive in
exchange therefor (subject to any taxes required to be withheld) certificates
evidencing the number of whole shares of AXENT Common Stock to which such
holder is entitled and any cash which may be payable in lieu of a fractional
share of AXENT Common Stock. Such transmittal forms will be accompanied by
instructions specifying other details of the exchange. RAPTOR'S STOCKHOLDERS
SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE A TRANSMITTAL FORM.
 
  After the Effective Time, each certificate evidencing Raptor Common Stock,
until so surrendered and exchanged, will be deemed, for all purposes, to
evidence only the right to receive the number of whole shares of AXENT Common
Stock which the holder of such certificate is entitled to receive and the
right to receive any cash payment in lieu of a fractional share of AXENT
Common Stock. The holder of such unexchanged certificate will not be entitled
to receive any dividends or other distributions payable by AXENT until the
certificate has been exchanged. Subject to applicable laws, such dividends and
distributions, together with any cash payment in lieu of a fractional share of
AXENT Common Stock, will be paid without interest.
 
 
                                      56

STOCK OPTION PLANS
 
  At the Effective Time, each outstanding option to purchase Raptor Common
Stock (each a "Raptor Option") under Raptor's 1995 Stock Option and Grant Plan
(the "Raptor Option Plan") and options issued outside of the Raptor Option
Plan, whether vested or unvested or subject to repurchase by Raptor following
such exercise, will be exchanged for an option issued under AXENT's Exchange
Plan to acquire, on the same terms and conditions as were applicable under
such Raptor Option, the number of shares of AXENT Common Stock (rounded down
to the next lower whole number) equal to the number of shares of Raptor Common
Stock issuable upon exercise of such Raptor Option multiplied by the
Conversion Ratio, at a price per share (rounded up to the next higher whole
cent) equal to the exercise price per share of such Raptor Option divided by
the Conversion Ratio. As of December 19, 1997, options to acquire 2,348,407
shares of Raptor Common Stock were outstanding.
 
  AXENT has agreed to reserve for issuance a sufficient number of shares of
AXENT Common Stock for delivery under the Raptor Options exchanged as
described above, which it will do under the Exchange Plan. As soon as
practicable after the Effective Time, and in any event no later than 30 days
after the Closing, AXENT will file a registration statement on Form S-8 (or
any successor form) under the Securities Act with respect to the shares of
AXENT Common Stock subject to such options and shall maintain the
effectiveness of such registration statement for so long as such options
remain outstanding.

majority of the shares of capital stock issued and outstanding and entitled to
vote, while the By-laws of Raptor provide that a special meeting of the
stockholders may be called only by the Board of Directors pursuant to an
affirmative vote of a majority of the Directors then in office.
 
ANNUAL MEETINGS OF STOCKHOLDERS
 
  The By-laws of AXENT are silent on the issue of stockholder's notice to
propose business to be transacted at an annual meeting, while the By-laws of
Raptor provide that to propose business to be transacted at an annual meeting,
a stockholder's timely notice must be received by Raptor not less than 75 days
nor more than 120 days prior to the anniversary date of the immediately
preceding annual meeting; provided, however, that in the event the annual
meeting is scheduled to be held more than 30 days before the anniversary date
of the immediately preceding annual meeting or more than 60 days after the
anniversary date of the preceding annual meeting, notice by the stockholder to
be timely must be so received not later than the close of business on the
later of the 75th day prior to the scheduled date of the annual meeting or the
15th day following the day on which public announcement of the date of such
annual meeting is first made by Raptor.
 
STAGGERED BOARD OF DIRECTORS
 
  Pursuant to their respective Certificates of Incorporation, each of AXENT
and Raptor have a staggered Board of Directors divided into three classes,
with each class serving for a term of three years. The existence of a
staggered board may have the effect of delaying or deferring a change of
control of AXENT or Raptor or removal of incumbent management.
 
QUORUM
 
  The By-laws of AXENT and Raptor both provide that the holders of a majority
of the shares of stock issued and outstanding and entitled to vote at
meetings, present in person or represented by proxy, shall constitute a quorum
for the transaction of business, and at any meeting of the Board of Directors
the presence of a majority of the directors then in office shall constitute a
quorum for the transaction of business.
 
ADJOURNMENTS OF STOCKHOLDER MEETINGS
 
  The By-laws of AXENT and Raptor both provide that if the adjournment of a
meeting of stockholders is for more than 30 days, or if after the adjournment
a new record date is fixed for the adjourned meeting, a notice of the
adjourned meeting shall be given to each stockholder of record entitled to
vote at the meeting.

REMOVAL OF DIRECTORS
 
  The By-laws of AXENT provide that directors (but not the entire Board of
Directors) may be removed, only for cause, by the holders of a majority of the
shares then entitled to vote at an election of directors, while the
Certificate of Incorporation of Raptor provides that, subject to the rights of
any series of Preferred Stock to elect or remove directors, any director may
be removed, but only for cause, by the affirmative vote of at least two-thirds
of the total votes that would be eligible to be cast by stockholders in the
election of such director.
 
NOMINATION OF DIRECTORS
 
  The By-laws of AXENT are silent on the issue of nomination of directors,
while the By-laws of Raptor provide that a stockholder's notice in connection
with the nomination of directors is timely if received by Raptor not less than
75 days nor more than 120 days prior to the anniversary date of the
immediately preceding annual meeting; provided, however, that in the event the
annual meeting is scheduled to be held more than 30 days before the
anniversary date of the immediately preceding annual meeting or more than 60
days after the anniversary date of the preceding annual meeting, notice by the
stockholder to be timely must be so received not later than the close of
business on the later of the 75th day prior to the scheduled date of the
annual meeting or the 15th day following the day on which public announcement
of the date of such annual meeting is first made by Raptor.
 
AMENDMENTS TO CERTIFICATE OF INCORPORATION
 
  The AXENT Certificate of Incorporation provides that it may be amended in
the manner prescribed by the DGCL or such Certificate of Incorporation;
provided, however, that the approval of holders of shares having at least two-
thirds of the voting power of the outstanding capital stock of AXENT is
required to amend provisions in the AXENT Certificate of Incorporation
addressing classification of the AXENT Board, the ability of stockholders to
take action by written consent and the amendment provisions thereof. The
Raptor Certificate of Incorporation provides that it may be amended, after
approval by the Raptor Board, by the affirmative vote of a majority of the
total votes eligible to be cast by holders of voting stock with respect to
such amendment at a duly constituted meeting called expressly for such
purpose; provided, however, that the approval of holders of shares having not
less than 80% of the total votes eligible to be cast by holders of voting
stock shall be required to amend or repeal provisions in the Raptor
Certificate of Incorporation addressing the Directors of Raptor or the
amendment provisions of thereof.
 
AMENDMENTS TO BY-LAWS
 
  The AXENT Certificate of Incorporation provides that the AXENT By-Laws may
be amended or repealed by the affirmative vote of a majority of the AXENT
Board, provided that notice of the proposal to amend or repeal such Bylaws, or
to adopt new bylaws, must be included in the notice of the of the meeting of
the Board of Directors at which such action takes place. The AXENT By-laws
provide that provisions therein addressing directors or the amendment
provisions thereof may only be amended by the stockholders of AXENT if
approved by at least two-thirds of the voting power of the outstanding AXENT
capital stock. The Raptor Certificate of Incorporation provides that the
Raptor By-laws may be amended or repealed by the Raptor Board. The Raptor By-
laws provide that they may be amended at any annual meeting of stockholders,
or special meeting of stockholders called for such purpose, by the affirmative
vote of at least two-thirds of the total votes eligible to be cast on such
amendment or repeal by holders of voting stock, voting together as a single
class; provided, however, that if the Raptor Board recommends that
stockholders approve such amendment or repeal at such meeting of stockholders,
such amendment or repeal shall only require the affirmative vote of a majority
of the total votes eligible to be cast on such amendment or repeal by holders
of voting stock, voting together as a single class.
 
WRITTEN CONSENT OF STOCKHOLDERS
 
  The Certificate of Incorporation of AXENT provides that at such time as
AXENT shall be subject to the reporting requirements of the Exchange Act, any
action required or permitted by law to be taken at a meting of
 
                                      68
<PAGE>
 
stockholders must be effected at a duly called annual or special meeting of
stockholders, and may not be effected by any consent in writing by such
stockholders, unless such consent is unanimous. Raptor's Certificate of
Incorporation provides that actions required or permitted to be taken by the
stockholders of Raptor at any annual or special meeting may not be taken or
effected by a written consent of stockholders in lieu thereof.

    PROPOSAL NO. II: APPROVAL OF AXENT'S 1998 EMPLOYEE STOCK PURCHASE PLAN
 
  The AXENT Board proposes that the stockholders of AXENT approve the 1998
Employee Stock Purchase Plan (the "Stock Purchase Plan"), pursuant to which
shares of AXENT's Common Stock would be issued to eligible employees of AXENT.
The following summary of the principal features of the Stock Purchase Plan is
a fair and complete summary of the Stock Purchase Plan; it is qualified in its
entirety by the full text of the Stock Purchase Plan, which appears as Annex D
to this Prospectus/Joint Proxy Statement.
 
GENERAL
 
  The purpose of the Stock Purchase Plan is to promote the success and enhance
the value of AXENT, by providing eligible employees of AXENT and its
participating subsidiaries with the opportunity to purchase Common Stock of
AXENT through payroll deductions. The Stock Purchase Plan is intended to
qualify as an employee stock purchase plan under Section 423 of the Code.
 
  The Stock Purchase Plan provides for the issuance of an aggregate of 500,000
shares of AXENT Common Stock to employees. In the event of a subdivision of
outstanding shares of AXENT Common Stock, payment of a stock divided in AXENT
Common Stock or other change affecting AXENT Common Stock, the AXENT Board or
the Committee responsible for administration of the Stock Purchase Plan (as
described below) will make appropriate and equitable adjustments in the
aggregate number of shares that may be issued under the Stock Purchase Plan.
The Stock Purchase Plan also permits the AXENT Board or the Committee to
require a period of service with AXENT or its participatory subsidiaries as a
condition for participation in the Stock Purchase Plan.
 
ELIGIBILITY TO RECEIVE AWARDS
 
  Employees of AXENT and participating subsidiaries, who are regularly
employed for 20 or more hours per week for more than five months in a calendar
year, are eligible to participate in the Stock Purchase Plan. However, if the
employee owns, or is deemed to own, 5% or more of the voting power or value of
the stock of AXENT or any subsidiary of AXENT, he or she is not eligible for
the Stock Purchase Plan. The Stock Purchase Plan also permits the Board or the
Committee to require a period of service with AXENT or its participating
subsidiaries as a condition for participation in the Stock Purchase Plan. As
of December 1, 1997, and assuming no required period of service, approximately
202 employees would be eligible to participate in the Stock Purchase Plan.
 
ADMINISTRATION, AMENDMENT AND TERMINATION
 
  The Stock Purchase Plan is administered by the AXENT Board or by a committee
appointed by the Board (the "Committee"). A member of the Board or the
Committee is not excluded from participating in the Stock Purchase Plan solely
by virtue of such membership.
 
  Subject to the terms of the Stock Purchase Plan, the Board and the Committee
has authority to make rules and regulations, and take any other appropriate
actions to administer the Stock Purchase Plan.
 
  The Board may amend the Stock Purchase Plan at any time for any reason,
provided that such amendment is made in compliance with Section 423 of the
Code. The Board, in its sole discretion, may terminate the Stock Purchase Plan
at any time and for any reason.
 
ENROLLMENT AND CONTRIBUTIONS
 
  The Stock Purchase Plan establishes periodic purchase periods ("Purchase
Periods") which initially will correspond with the calendar quarters
commencing April 1, 1998. A Purchase period begins on the first day Nasdaq is
open for trading on or after January 1 of a calendar year, or such other date
as specified by the Committee and shall have a duration as determined by the
Committee, but in no event in excess of 27 months.
 
 
                                      70
<PAGE>
 
  An employee who satisfies the eligibility requirements described above on
the first day of a Purchase Period may enroll in the Stock Purchase Plan as of
the first day of the Purchase Period by authorizing payroll deduction from his
or her compensation for the Purchase Period of any whole number percentage of
such compensation up to 10%. For this purpose, "compensation" is defined by
the Stock Purchase Plan to mean taxable income for federal income tax purposes
(including sales commissions), but excludes overtime, shift premiums,
incentive bonus awards, allowances and reimbursements for relocation, travel
and other expenses, income from stock options and stock appreciation rights,
elective contributions to AXENT's 401(k) plan or cafeteria plan (within the
meaning of Section 125 of the Code) and similar items.
 
  Eligible employees are re-enrolled automatically for each new Purchase
Period. Participating employees may discontinue the contribution percentage
once during any Purchase Period by submitting a new payroll deduction
authorization form, but may not increase the contribution percentage during a
Purchase Period. A participating employee also may on any one occasion during
any Purchase Period elect to withdraw all or a portion of his or her payroll
deduction amounts for the Purchase Period. However, if the participant
withdraws all payroll deduction amounts, he or she will be deemed to have
terminated participation in the Stock Purchase Plan and may not enroll again
until the beginning of the next Purchase Period.
 
  On the last business day of each Purchase Period (the "Exercise Date"), the
employee's accumulated payroll deductions are used to purchase shares of
AXENT's Common Stock for the employee. The price of the shares purchased will
be the lower of (i) 85% of the stock's closing price on the first trading day
for AXENT's Common Stock during the applicable Purchase Period or (ii) 85% of
the stock's closing price on the Exercise Date. The maximum aggregate number
of shares which an employee may purchase under the Stock Purchase Plan in a
single calendar year is equal to $25,000, divided by the fair market value (as
defined in the Stock Purchase Plan) of such Common Stock.
 
  Certificates for shares purchased under the Stock Purchase Plan during any
Purchase Period are delivered to the participant as soon as practicable after
the end of the Purchase Period. Stock Purchase Plan participants have no
rights as a stockholder of AXENT until shares have been purchased under the
Stock Purchase Plan and issued to the participant.
 
  Because the number of shares of AXENT Common Stock that may be purchased by
any participant in the Stock Purchase Plan is based on the fair market value
of such shares on future dates and on the participant's decision to purchase
shares, the benefits or amounts that will be received by Stock Purchase Plan
participants are not currently determinable. No purchases will be made under
the Stock Purchase Plan prior to approval of the Stock Purchase Plan by the
stockholders.
 
  Participation in the Stock Purchase Plan terminates when a participating
employee's employment with AXENT or its participating subsidiaries ceases for
any reason, the employee withdraws, or the Stock Purchase Plan is terminated
or amended such that the employee is no longer eligible to participate.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  An employee will not have taxable income when the shares of AXENT Common
Stock are purchased for that employee, but income taxes generally will be due
when the employee sells or otherwise disposes of stock purchased through the
Stock Purchase Plan.
 
  If the employee disposes of shares acquired under the Stock Purchase Plan
before the expiration of two years from the beginning of the Purchase Period
in which the shares were purchased, or within one year of the date on which
the shares were purchased, the employee generally will recognize ordinary
income on the disposition date equal to the difference between the fair market
value of the shares on the date they were purchased and the purchase price.
Any amount realized on the disposition of those shares in excess of the fair
market value on the purchase date generally will be treated as long-term or
short-term capital gain, depending on the holding period for such shares.
 
                                      71
<PAGE>
 
  If the employee disposes of shares acquired under the Stock Purchase Plan
after expiration of the two-year and one-year periods described above, the
employee will recognize ordinary income equal to the lesser of (1) the excess
of the fair market value of the shares at the time of the disposition over the
amount paid for the shares or (2) the excess of the fair market value of the
shares at the beginning of the Purchase Period in which they were acquired
over the purchase price of the shares under the Stock Purchase Plan determined
as if shares were purchased on the first day of the Purchase Period. Any
amount recognized as ordinary income as a result of such a disposition will
reduce the amount of gain otherwise realized on the disposition.
 
  As a general rule, AXENT will not be entitled to a deduction for federal
income tax purposes as a result of employee participation in the Stock
Purchase Plan. However, if an employee recognizes ordinary income as a result
of the disposition of shares before expiration of the two-year and one-year
periods described above, AXENT generally will be entitled to a deduction for
federal income tax purposes corresponding in timing and amount to the ordinary
income recognized by the employee.
 
REQUIRED VOTE
 
  Adoption of the Stock Purchase Plan requires the affirmative vote of the
holders of a majority of the outstanding shares of AXENT Common Stock present
at the AXENT Special Meeting, in person or by proxy, with respect to such
matter and entitled to vote.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
  THE AXENT BOARD RECOMMENDS A VOTE "FOR" THE ADOPTION OF THE 1998 EMPLOYEE
STOCK PURCHASE PLAN.
 
                                      72

        PROPOSAL NO. III: APPROVAL OF AXENT'S 1998 INCENTIVE STOCK PLAN
 
  The AXENT Board proposes that the stockholders of AXENT approve the 1998
Incentive Stock Plan (the "Option Plan"). The following is a fair and complete
summary of the Option Plan as proposed to be adopted; it is qualified in its
entirety by reference to the full text of the Option Plan, which appears as
Annex E to this Prospectus/Joint Proxy Statement.
 
GENERAL
 
  Purpose: The purpose of the Option Plan as proposed is to promote the long-
term growth and profitability of AXENT by providing key people with incentives
to improve stockholder value and contribute to the growth and financial
success of AXENT, and by enabling AXENT to attract, retain and reward the
best-available persons for positions of substantial responsibility.
 
  Shares Available under the Option Plan: The number of shares of AXENT Common
Stock that may be issued with respect to awards granted under the proposed
Option Plan shall not exceed an aggregate of 1,800,000 shares of AXENT Common
Stock. The maximum number of shares of AXENT Common Stock subject to awards of
any combination that may be granted during any one fiscal year of AXENT to any
one individual shall be limited to 500,000. These limits are subject to
adjustment to reflect any stock dividends, split-ups, recapitalizations,
mergers, consolidations, business combinations or exchanges of shares and the
like. If any award, or portion of an award, under the Option Plan expires or
terminates unexercised, becomes unexercisable or is forfeited or otherwise
terminated, surrendered or canceled as to any shares, or if any shares of
AXENT Common Stock are surrendered to AXENT in connection with any award
(whether or not such surrendered shares were acquired pursuant to any award),
the shares subject to such award and the surrendered shares shall thereafter
be available for further awards under the Option Plan.
 
  Administration: The proposed Option Plan will be administered by the AXENT
Board or by such committee or committees as may be appointed by the AXENT
Board from time to time (the AXENT Board, committee or committees hereinafter
referred to as the "Administrator"). The Administrator shall have full power
and authority to take all other actions necessary to carry out the purpose and
intent of the Option Plan, including, but not limited to, the authority to:
(i) determine the eligible persons to whom, and the time or times at which
awards shall be granted; (ii) determine the types of awards to be granted;
(iii) determine the number of shares to be covered by or used for reference
purposes for each award; (iv) impose such terms, limitations, restrictions and
conditions upon any such award as the Administrator shall deem appropriate;
(v) modify, amend, extend or renew outstanding awards, or accept the surrender
of outstanding awards and substitute new awards (provided however, that,
except as noted below, any modification that would materially adversely affect
any outstanding award shall not be made without the consent of the holder);
(vi) accelerate or otherwise change the time in which an award may be
exercised or becomes payable and to waive or accelerate the lapse, in whole or
in part, of any restriction or condition with respect to such award,
including, but not limited to, any restriction or condition with respect to
the vesting or exercisability of an award following termination of any
grantee's employment; and (vii) establish objectives and conditions, if any,
or earning awards and determining whether awards will be paid after the end of
a performance period.
 
  In the event of changes in the AXENT Common Stock by reason of any stock
dividend, split-up, recapitalization, merger, consolidation, business
combination or exchange of shares and the like, the Administrator shall, in
its discretion, make appropriate adjustments to the maximum number and kind of
shares reserved for issuance or with respect to which awards may be granted
under the Option Plan and to the number, kind and price of shares covered by
awards granted, and shall, in its discretion and without the consent of
holders of awards, make any other adjustments in awards, including but not
limited to reducing the number of shares subject to awards or providing or
mandating alternative settlement methods such as settlement of the awards in
cash or in shares of AXENT Common Stock or other securities of AXENT or of any
other entity, or in any other matters which relate to awards as the
Administrator shall, in its sole discretion, determine to be necessary or
appropriate.
 
                                      73
<PAGE>
 
  Without the consent of holders of awards, the Administrator, in its sole
discretion, may make any modifications to any awards, including but not
limited to cancellation, forfeiture, surrender or other termination of the
awards in whole or in part regardless of the vested status of the award, in
order to facilitate any business combination that is authorized by the AXENT
Board to comply with requirements for treatment as a pooling-of-interests
transaction for accounting purposes under generally accepted accounting
principles.
 
  Without the consent of holders of awards, the Administrator in its
discretion is authorized to make adjustments in the terms and conditions of,
and the criteria included in, awards in recognition of unusual or nonrecurring
events affecting AXENT, or the financial statements of AXENT or any
subsidiary, or of changes in applicable laws, regulations, or accounting
principles, whenever the Administrator determines that such adjustments are
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Option Plan.
 
  The Option Plan provides for the automatic acceleration of vesting or
exercisability of awards in the event of any "Change of Control" (as defined
in the Option Plan). That provision is identical to an alternate acceleration
provision in AXENT's current Amended and Restated 1996 Stock Option Plan.
 
ELIGIBILITY TO RECEIVE AWARDS
 
  Participation in the Option Plan will be open to all employees, officers,
directors and consultants of AXENT or any of its affiliates, as may be
selected by the Administrator from time to time. As of December 1, 1997, all
five non-employee directors and approximately 247 employees consultants would
be eligible to participate in the Option Plan.
 
TYPE OF AWARDS
 
  The Option Plan as proposed would allow stock options, stock appreciation
rights, stock awards, phantom stock awards and performance awards to be
granted. These awards may be granted separately or in tandem with other
awards. The Administrator will determine the prices, expiration dates and
other material conditions upon which such awards may be exercised.
 
  Stock Options: The proposed Option Plan allows the Administrator to grant
either awards of incentive stock options as that term is defined in section
422 of the Code or nonqualified stock options; provided, however, that awards
of incentive stock options shall be limited to employees of AXENT or of any
subsidiary of AXENT. Options intended to qualify as incentive stock options
under Section 422 of the Code must have an exercise price at least equal to
fair market value on the date of grant, but nonqualified stock options may be
granted with an exercise price less than fair market value. The option
exercise price may be paid in cash, by tender of shares of AXENT Common Stock,
by a combination of cash and shares, or by any other means the Administrator
approves.
 
  Stock Appreciation Rights: The proposed Option Plan allows the Administrator
to grant awards of Stock Appreciation Rights ("SAR"). An SAR entitles the
holder to receive a payment in cash, in shares of AXENT Common Stock, or in a
combination of both, having an aggregate value equal to the product of (i) the
excess of (A) the fair market value on the exercise date of one share of AXENT
Common Stock over (B) the base price per share specified in the grant
agreement, times (ii) the number of shares specified by the SAR, or portion
thereof, which is exercised.
 
  Stock and Phantom Stock Awards: The proposed Option Plan allows the
Administrator to grant restricted or unrestricted stock awards, or awards
denominated in stock-equivalent units ("phantom stock") to eligible
participants with or without payment of consideration by the grantee. Stock
awards and phantom stock awards may be paid in cash, in shares of AXENT Common
Stock, or in a combination of both.
 
  Performance awards: The proposed Option Plan allows the Administrator to
grant performance awards which become payable in cash, in shares of AXENT
Common Stock, or in a combination of both, on account of
 
                                      74
<PAGE>
 
attainment of one or more performance goals established by the Administrator.
Performance goals established by the Administrator may be based on AXENT's or
an affiliate's operating income or one or more other business criteria
selected by the Administrator that apply to an individual or group of
individuals, a business unit, or AXENT or an affiliate as a whole, over such
performance period as the Administrator may designate.
 
AWARDS UNDER THE OPTION PLAN
 
  Because participation and the types of awards granted under the Option Plan
as proposed are subject to the discretion of the Administrator, the benefits
or amounts that will be received by any participant or groups of participants
if the Option Plan is approved are not currently determinable.
 
AMENDMENT AND TERMINATION
 
  The AXENT Board may terminate, amend or modify the Option Plan or any
portion thereof at any time.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a general summary of the current federal income tax
treatment of stock options, which would be authorized to be granted under the
Option Plan as proposed, based upon the current provisions of the Code and
regulations promulgated thereunder. The discussion set forth below, insofar as
it relates to the deductibility of any compensation payable under the Option
Plan, is subject to the paragraph captioned "Disallowance of Deductions"
relating to compensation in excess of $1,000,000 payable to certain executive
officers.
 
  Incentive Stock Options: Incentive stock options under the Option Plan are
intended to meet the requirements of Section 422 of the Code. No tax
consequences result from the grant of the option. If an option holder acquires
stock upon the exercise, no income will be recognized by the option holder for
ordinary income tax purposes (although the difference between the option
exercise price and the fair market value of the stock subject to the option
may result in alternative minimum tax liability to the option holder) and
AXENT will be allowed no deduction as a result of such exercise, provided that
the following conditions are met: (a) at all times during the period beginning
with the date of the granting of the option and ending on the day three months
before the date of such exercise, the option holder is an employee of AXENT or
of a subsidiary; and (b) the option holder makes no disposition of the stock
within two years from the date the option is granted nor within one year after
the stock is transferred to the option holder. The three-month period is
extended to one year in the event of disability and is waived in the event of
death of the employee. In the event of a sale of such stock by the option
holder after compliance with these conditions, any gain realized over the
price paid for the stock ordinarily will be treated as long-term capital gain,
and any loss will be treated as long-term capital loss, in the year of the
sale.
 
  If the option holder fails to comply with the employment requirement
discussed above, the tax consequences will be the same as for a nonqualified
option, discussed below. If the option holder fails to comply with the holding
period requirements discussed above, the option holder will recognize ordinary
income in an amount equal to the lesser of (i) the excess of the fair market
value of the stock on the date the option was exercised over the exercise
price or (ii) the excess of the amount realized upon such disposition over the
exercise price. Any additional gain ordinarily will be recognized by the
option holder as capital gain, either long-term or short-term, depending on
the holding period of the shares. If the option holder is treated as having
received ordinary income because of his or her failure to comply with either
condition above, an equivalent deduction will be allowed to AXENT in the same
year.
 
  Nonqualified Stock Options: No tax consequences result from the grant of the
option. An option holder who exercises a nonqualified stock option with cash
generally will realize compensation taxable as ordinary income in an amount
equal to the difference between the exercise price and the fair market value
of the shares on the date of exercise, and AXENT will be entitled to a
deduction from income in the same amount in the fiscal
 
                                      75
<PAGE>
 
year in which the exercise occurred. The option holder's basis in such shares
will be the fair market value on the date income is realized, and when the
holder disposes of the shares he or she will recognize capital gain or loss,
either long-term or short-term, depending on the holding period of the shares.
 
  Disallowance of Deductions: The Code disallows deductions for publicly held
corporations with respect to compensation in excess of $1,000,000 paid to the
corporation's chief executive officer and its four other most highly
compensated officers. However, compensation payable solely on account of
attainment of one or more performance goals is not subject to this deduction
limitation if the performance goals are objective, pre-established and
determined by a compensation committee comprised solely of two or more outside
directors, the material terms under which the compensation is to be paid are
disclosed to the stockholders and approved by a majority vote, and the
compensation committee certifies that the performance goals and other material
terms were in fact satisfied before the compensation is paid. Under this
exception, the deduction limitation does not apply with respect to
compensation otherwise deductible on account of stock options and stock
appreciation rights granted at fair market value under a plan which limits the
number of shares that may be issued to any individual and which is approved by
AXENT's stockholders.
 
REQUIRED VOTE
 
  Adoption of the Option Plan requires the affirmative vote of the holders of
a majority of outstanding shares of AXENT Common Stock present at the Special
Meeting, in person or by proxy, with respect to such matter and entitled to
vote.
 
RECOMMENDATION OF THE BOARD
 
  THE AXENT BOARD RECOMMENDS A VOTE "FOR" THE ADOPTION OF THE 1998 INCENTIVE

(2) Based on options to purchase 463,500 shares of AXENT Common Stock granted
    during 1996.
(3) All stock options were granted with exercise price equal to the fair
    market value of AXENT Common Stock, as determined by the Board of
    Directors, on the grant date. After AXENT's initial public offering, the

    stock option exercises are dependent on future performance of the AXENT
    Common Stock, overall market conditions, as well as the option holder's
    continued employment throughout the vesting period. The amounts

SEVERANCE ARRANGEMENTS
 
  A Memorandum of Understanding (the "Memorandum") dated as of July 22, 1997
between Richard Lefebvre and the members of AXENT's Compensation Committee, on
behalf of AXENT's Board, sets out the compensation arrangements regarding Mr.
Lefebvre's service as AXENT's Chairman of the Board to and including August
31, 1999 (or to and including July 31, 2000, if so elected by AXENT's Chief
Executive Officer) and related severance arrangements. The Memorandum provides
that Mr. Lefebvre will receive salary at the annual rate of $200,000 through
July 21, 1999 and at the annual rate of $160,000 from July 22, 1999 through
July 21, 2000, bonus for 1997 as provided in AXENT's bonus plan in effect on
the date of the Memorandum and bonus of up to $80,000 for 1998, car allowance
at the rate in effect at the date of the Memorandum through July 21, 1999 and
all employee benefits made available to full-time employees of AXENT through
July 21, 2000. In addition, the Memorandum provides that the AXENT Board will
amend any unexercised stock options held by Mr. Lefebvre and vested at July
31, 1999 so as to be exercisable until the earlier of July 31, 2000 or the
specified expiration date of such options. In the event of a change of control
(as defined in AXENT's Amended and Restated 1996 Stock Option Plan in effect
at the date of the Memorandum), the Memorandum provides that all compensation
payable to Mr. Lefebvre through July 21, 2000 (including the maximum bonus
payable with respect to 1998) will be payable in a lump sum; in addition, the
Memorandum provides that the AXENT Board will accelerate all stock options
issued to Mr. Lefebvre to be fully exercisable prior to the earliest date on
which the change of control may be deemed to occur and will provide that all
exercisable portions of such stock options will be assumed by any acquiring or
successor corporation and will be exercisable for a specified period after the
change of control occurs.
 
  In the event AXENT terminates the employment of an officer without cause,
the officer is entitled to receive certain severance benefits in accordance
with AXENT's severance policy, as follows: (1) President and Chief Executive
Officer--one year; (2) Senior Vice Presidents and Executive Vice Presidents
employed for three years or more and the Chief Financial Officer--one year;
(3) the General Counsel--nine months; (4) Senior Vice Presidents and Executive
Vice Presidents employed for one year or more, but less than three years--six
months; and (5) Vice Presidents and Senior Vice Presidents employed for less
than one year--three months. Accordingly, Messrs. Becker, Jackson and
Privateer each would be entitled to receive the compensation and benefits
otherwise payable to him for a period of one year, and Mr. McDonough would be
entitled to receive the compensation and benefits otherwise payable to him for
a period of three months, following termination without cause, the sale of
AXENT or a decrease in his duties.

EXECUTIVE BONUS PLAN
 
  AXENT has an executive bonus plan designed to attract, retain and provide
performance incentives for key management personnel. The plan provides for a
cash bonus to be paid to the key management personnel upon attainment of
individualized predetermined performance objectives. Awards made to management
under the plan are determined by the Compensation Committee. For 1997, Messrs.
Lefebvre, Becker, Jackson, Privateer and McDonough will be eligible for annual
bonus payments in amounts up to $120,000, $116,000, $96,000, $72,000 and

                                  LITIGATION
 
  On December 4, 1997, an action entitled Usher Fisher v. William S. Kaiser,
et al., Del. Ch., C.A. No. 16072-NC, was filed in the Delaware Court of
Chancery in and for New Castle County, purportedly as a class action on behalf
of stockholders of Raptor, against Raptor, the members of the Raptor Board,
and AXENT. The complaint alleges that Raptor and the Raptor Board breached
their fiduciary duties in connection with the approval of the Merger. The
complaint seeks to enjoin consummation of the Merger under the terms presently
proposed and also seeks unspecified damages. Raptor and the Raptor Board
believe that the Merger is fair to, and in the best interests of, Raptor and
its stockholders. Raptor and AXENT believe that the allegations in the
complaint are without merit and will defend the action vigorously.

                         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 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

  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 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
 
                                       2
<PAGE>
 
  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 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 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
 
                                       3
<PAGE>
 
  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).
 
    (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

(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

"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

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

  Since September 30, 1997, there has not been any material adverse change in

  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.

    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, is
    liable to pay by law.
 
      (ii) For purposes of this Agreement, "Tax Returns" means all reports,
    returns, declarations, statements or other information required to be
    supplied to a taxing authority in connection with Taxes.
 
      (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.

  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.

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)

liabilities or obligations with respect to which no material default exists

sublicenses and agreements referred to above and as amended to date. Except
for retail purchases of software, neither Raptor nor any of its Subsidiaries
is a party to any oral license, sublicense or agreement which, if reduced to
written form, would be required to be listed in Section 2.12 of the Disclosure
Schedule under the terms of this Section 2.12(a).
 
  (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

  set forth in the federal Comprehensive Environmental Compensation,
  Liability and Response Act of 1980 ("CERCLA").

  liability under the Environmental Laws. Raptor is not aware of any other

  pollutants or contaminants, hazardous substances (as such term is defined
  under CERCLA), solid wastes and hazardous wastes (as such terms are defined

  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 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

  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.

  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

<PAGE>
 
  Raptor, which provisions shall not be amended, repealed or otherwise
  modified for a period of six years from the Effective Time in any manner
  that would adversely affect the rights thereunder as of the Effective Time
  of individuals who at the Effective Time were directors, officers,
  employees or agents of Raptor or its Subsidiaries, unless such modification
  is required after the Effective Time by law. At or prior to the Effective
  Time, Axent shall purchase or assume directors' and officers' liability
  insurance coverage for Raptor's directors and officers in a form acceptable
  to Raptor which shall provide such directors and officers with coverage on
  substantially similar terms as currently provided by Raptor for a period of

  permitted under applicable law or under Raptor's current Certificate of
  Incorporation or By-laws, indemnify and hold harmless each present and
  former director, officer, employee or agent of Raptor or any of its

  request of Raptor or any of its Subsidiaries, of another corporation,
  partnership, joint venture, trust or enterprise (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 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
 
                                      31
<PAGE>
 
  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.

  of this Agreement);
 
    (d) any party may terminate this Agreement by giving written notice to

  1998 (provided, however, that the right to terminate this Agreement under
  this Section 6.1(d) shall not be available to any party whose failure to

  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.

of the corporation existing at the time of such repeal or amendment.
 
  NINTH. Election of Directors. Elections of directors need not be by written
ballot unless the by-laws of the corporation shall so provide.

(subject to any provision contained in applicable statutes) outside the State
of Delaware at such place or places as may be designated from time to time by
the board of directors or in the bylaws of the corporation.
 
  TWELFTH. Right to Amend. The corporation reserves the right to amend, alter,
change or repeal any provision contained in this certificate of incorporation
and in any certificate amendatory hereof, in the manner now or hereafter

  THIRTEENTH. Indemnification. The corporation shall, to the fullest extent
permitted by Section 145 of the General Corporation Law of Delaware, as
amended from time to time, indemnify each person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative,
by reason of the fact that he is or was, or has agreed to become, a director
or officer of the corporation, or is or was serving, or has agreed to serve,
at the request of the corporation, as a director, officer or trustee of, or in
a similar capacity with, another corporation, partnership, joint venture,
trust or other enterprise (including any employee benefit plan), or by reason
of any action alleged to have been taken or omitted in such capacity, against
all expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him or on his behalf in
connection with such action, suit or proceeding and any appeal therefrom.
 
  Indemnification may include payment by the corporation of expenses in
defending an action or proceeding in advance of the final disposition of such
action or proceeding upon receipt of an undertaking by the person indemnified
to repay such payment if it is ultimately determined that such person is not
entitled to indemnification under this Thirteenth Article, which undertaking
may be accepted without reference to the financial ability of such person to
make such repayment.
 
  The corporation shall not indemnify any such person seeking indemnification
in connection with a proceeding (or part thereof) initiated by such person
unless the initiation thereof was approved by the board of directors of the
corporation.
 
  The indemnification rights provided in this Thirteenth Article (i) shall not
be deemed exclusive of any other rights to which those indemnified may be
entitled under any law, agreement or vote of stockholders or disinterested
directors or otherwise, and (ii) shall inure to the benefit of the heirs,
executors and administrators of such persons. The corporation may, to the
extent authorized from time to time by its board of directors, grant
indemnification rights to other employees or agents of the corporation or
other persons serving the corporation and such rights may be equivalent to, or
greater or less than, those set forth in this Thirteenth Article.

the State of Delaware, do make this certificate, hereby declaring and

stockholder. Such list shall be open to the examination of any stockholder
during ordinary business hours, for a period of at least ten days prior to the
election, either at a place within the city, town or village where the

business except as otherwise provided by statute or by the certificate of

meeting at which a quorum shall be present or represented any business may be
transacted which might have been transacted at the meeting as originally
notified.
 
  Section 2.9 When a quorum is present at any meeting, the vote of the holders
of a majority of the stock having voting power present in person or
represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which by express provision of the statutes or
of the certificate of incorporation, a different vote is required in which
case such express provision shall govern and control the decision of such
question.
 
  Section 2.10 Each stockholder shall at every meeting of the stockholders be
entitled to one vote in person or by proxy for each share of the capital stock
having voting power held by such stockholder, but no proxy shall be voted on
after three years from its date, unless the proxy provides for a longer
period, and, except where the transfer books of the corporation have been
closed or a date has been fixed as a record date for the determination of its
stockholders entitled to vote, no share of stock shall be voted on at any
election for directors which has been transferred on the books of the
corporation within twenty days next preceding such election of directors.

meeting of stockholders, or any action which may be taken at any annual or

prior notice and without a vote, if a consent in writing, setting forth the
action so taken, shall be signed by the holders of outstanding stock having
not less than the minimum number of votes that would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted. Prompt notice of the taking of the corporate action
without a meeting by less than unanimous written consent shall be given to
those stockholders who have not consented in writing.

directors which may exercise all such powers of the corporation and do all

notice at such time and at such place as shall from time to time be determined

constitute a quorum for the transaction of business and the act of a majority
of the directors present at any meeting at which there is a quorum shall be
the act of the board of directors, except as may be otherwise specifically
provided by statute or by the certificate of incorporation. If a quorum shall
not be present at any meeting of the board of directors, the directors present
thereat may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present.
 
  Section 3.9 Unless otherwise restricted by the certificate of incorporation
or these by-laws, any action required or permitted to be taken at any meeting
of the board of directors or of any committee thereof may be taken without a
meeting, if all members of the board or of such committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the board or committee.
 
                            COMMITTEES OF DIRECTORS
 
  Section 3.10 The board of directors may, by resolution passed by a majority
of the whole board, designate one or more committees, each committee to
consist of one or more of the directors of the corporation. In the absence or
disqualification of a member of a committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he or
they constitute a quorum, may unanimously appoint another member of the board
of directors to act at the meeting in the place of any such absent or
disqualified member. Any such committee, to the extent provided in the
resolution of the board of directors, shall have and may exercise all the
powers and authority of the board of directors in the management of the
business and affairs of the corporation, and may authorize the seal of the
corporation to be affixed to all papers which may require it; but no such
committee shall have the power or authority in reference to amending the
certificate of incorporation, adopting an agreement of merger or
consolidation, recommending to the stockholders the sale, lease or exchange of
all or substantially all of the corporation's property and assets,
recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution or amending the by-laws of the corporation; and,
unless the resolution expressly so provides, no such committee shall have the
power or authority to declare a dividend or to authorize the issuance of
stock.
 
  Section 3.11 Each committee shall keep regular minutes of its meetings and
report the same to the board of directors when required.
 
                           COMPENSATION OF DIRECTORS

communications equipment by means of which all persons participating in the
meeting can hear each other, and participation in a meeting pursuant to this
subsection shall constitute presence in person at such meeting.

                                    Notices

delivered personally or mailed to the directors or stockholders at their
addresses appearing on the books of the corporation. Notice by mail shall be
deemed to be given at the time when the same shall be mailed. Notice to
directors may also be given by telegram.
 
  Section 4.2 Whenever any notice is required to be given under the provisions
of the statutes or of the certificate of incorporation or by these by-laws, a
waiver thereof in writing, signed by the person or persons entitled to said
notice, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular, or special meeting of the stockholders, directors, or members of a
committee of directors need be specified in any written waiver of notice.

directors and all meetings of the stockholders and record all the proceedings
of the meetings of the corporation and of the board of directors in a book to

                             Certificates of Stock
 
  Section 6.1 Every holder of stock in the corporation shall be entitled to
have a certificate signed by, or in the name of the corporation by, the
chairman or vice-chairman of the board of directors, or president or a vice-
president and the treasurer or an assistant treasurer, or the secretary or an
assistant secretary of the corporation, certifying the number of shares owned
by him in the corporation.
 
  Section 6.2 Where a certificate is signed (l) by a transfer agent or an
assistant transfer agent or (2) by a transfer clerk acting on behalf of the
corporation and a registrar, the signature of any such chairman or vice-
chairman of the board of directors, president, vice-president, treasurer,
assistant treasurer, secretary or assistant secretary may be facsimile. In
case any officer or officers who have signed, or whose facsimile signature or
signatures have been used on, any such certificate or certificates shall cease
to be such officer or officers of the corporation, whether because of death,
resignation or otherwise, before such certificate or certificates have been
delivered by the corporation, such certificate or certificates may
nevertheless be adopted by the corporation and be issued and delivered as
though the person or persons who signed such certificate or certificates or
whose facsimile signature or signatures have been used thereon had not ceased
to be such officer or officers of the corporation.
 
                               LOST CERTIFICATES
 
  Section 6.3 The board of directors may direct a new certificate or
certificates to be issued in place of any certificate or certificates
theretofore issued by the corporation alleged to have been lost or destroyed,
upon the making of an affidavit of that fact by the person claiming the
certificate of stock to be lost or destroyed. When authorizing such issue of a
new certificate or certificates, the board of directors may, in its discretion
and as a condition precedent to the issuance thereof, require the owner of
such lost or destroyed certificate or certificates, or his legal
representative, to give the corporation a bond in such sum as it may direct as
indemnity against any claim that may be made against the corporation with
respect to the certificate alleged to have been lost or destroyed upon the
issuance of such new certificate.
 
                              TRANSFERS OF STOCK
 
  Section 6.4 Upon surrender to the corporation or the transfer agent of the
corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignment or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transactions upon its
books, unless the corporation has a duty to inquire as to adverse claims with
respect to such transfer which has not been discharged. The corporation shall
have no duty to inquire into adverse claims with respect to such transfer
unless (a) the corporation has received a written notification of an adverse
claim at a time and in a manner which affords the corporation a reasonable
opportunity to act on it prior to the issuance of a new, reissued or re-
registered share certificate and the notification identifies the claimant, the
registered owner and the issue of which the share or shares is a part and
provides an address for communications directed to the claimant; or (b) the
corporation has required and obtained, with respect to a fiduciary, a copy of
a will, trust, indenture, articles of co-partnership, by-laws or other
controlling instruments, for a purpose other than to obtain appropriate
evidence of the appointment or incumbency of the fiduciary, and such documents
indicate, upon reasonable inspection, the existence of an adverse claim.
 
  Section 6.5 The corporation may discharge any duty of inquiry by any
reasonable means, including notifying an adverse claimant by registered or
certified mail at the address furnished by him or, if there be no such
address, at his residence or regular place of business that the security has
been presented for registration of transfer by a named person, and that the
transfer will be registered unless within thirty days from the date of mailing
the notification, either (a) an appropriate restraining order, injunction or
other process issues from a court
 
                                       6
<PAGE>
 
of competent jurisdiction; or (b) an indemnity bond, sufficient in the
corporation's judgment to protect the corporation and any transfer agent,
registrar or other agent of the corporation involved from any loss which it or
they may suffer by complying with the adverse claim, is filed with the
corporation.
 
                              FIXING RECORD DATE
 
  Section 6.6 (a) In order that the corporation may determine the stockholders
entitled to notice or to vote at any meeting of stockholders or any
adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of
any other lawful action, the board of directors may fix, in advance, a record
date, which shall not be more than sixty nor less than ten days before the
date of such meeting, nor more than sixty days prior to any other action.
 
  (b) If no record date is fixed:
 
    (1) The record date for determining stockholders entitled to notice of or
  to vote at a meeting of stockholders shall be at the close of business on
  the day next preceding the day on which notice is given, or, if notice is
  waived, at the close of business on the day next preceding the day on which
  the meeting is held.
 
    (2) The record date for determining stockholders entitled to express
  consent to corporate action in writing without a meeting, when no prior
  action by the board of directors is necessary, shall be the day on which
  the first written consent is expressed.
 
    (3) The record date for determining stockholders for any other purpose
  shall be at the close of business on the day on which the board of
  directors adopts the resolution relating thereto.
 
  (c) A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the board of directors may fix a new record
date for the adjourned meeting.
 
                            REGISTERED STOCKHOLDERS
 
  Section 6.7 Prior to due presentment for transfer of any share or shares,
the corporation shall treat the registered owner thereof as the person
exclusively entitled to vote, to receive notifications and to all other
benefits of ownership with respect to such share or shares, and shall not be
bound to recognize any equitable or other claim to or interest in such share
or shares on the part of any other person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                Indemnification
 
  Section 9.1 The corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding
if he acted in good faith and in a manner he reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful. The termination of any action, suit or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his
conduct was unlawful.

  Section 9.2 The corporation shall indemnify any person who was or is a
party, or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred
by him in connection with the defense or settlement of such action or suit if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.
 
  Section 9.3 To the extent that a director, officer, employee or agent of the
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in sections 9.1 or 9.2 of this Article,
or in defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred
by him in connection therewith.
 
  Section 9.4 Any indemnification under sections 9.1 or 9.2 of this Article
(unless ordered by a court) shall be made by the corporation only as
authorized in the specific case upon a determination that indemnification of
the director, officer, employee or agent is proper in the circumstances
because he has met the applicable standard of conduct set forth in such
section. Such determination shall be made:
 
    1. By the board of directors by a majority vote of a quorum consisting of
  directors who were not parties to such action, suit or proceeding, or
 
    2. If such a quorum is not obtainable, or, even if obtainable a quorum of
  disinterested directors so directs, by independent legal counsel in a
  written opinion, or
 
    3. By the stockholders.
 
  Section 9.5 Expenses incurred in defending a civil or criminal action, suit
or proceeding may be paid by the corporation in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking
by or on behalf of the director, officer, employee or agent to repay such
amount if it shall ultimately be determined that he is not entitled to be
indemnified by the corporation as authorized in this Article. Such expenses
incurred by other employees and agents may be so paid upon such terms and
conditions, if any, as the board of directors deems appropriate.
 
  Section 9.6 The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article shall not be deemed exclusive of any other
rights to which those seeking indemnification or advancement of expenses may
be entitled under any agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office.
 
  Section 9.7 The corporation shall have power to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee
or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against him and incurred by him in any such capacity, or arising out
of his status as such, whether or not the corporation would have the power to
indemnify him against such liability under the provisions of this Article.
 
  Section 9.8 The indemnification and advancement of expenses provided by or
granted pursuant to, this Article IX shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

                               DECEMBER 1, 1997
 
AXENT Technologies, Inc.
2400 Research Boulevard, Suite 200
Rockville, Maryland 20850
 
Dear Sirs:
 
  An Agreement and Plan of Merger dated as of December 1, 1997 (the "Merger
Agreement") has been entered into 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 (the "Company" or "Raptor"). The
Merger Agreement provides for the merger of the Transitory Subsidiary with and
into the Company (the "Merger"). In accordance with the Merger Agreement, the
Raptor Common Stock (as defined in the Merger Agreement) owned by the
undersigned at the Effective Time (as defined in the Merger Agreement) shall
be converted into shares of common stock $.02 par value per share, of AXENT
(the "AXENT Common Stock"), as described in the Merger Agreement.
 
  In consideration of the mutual agreements, provisions and covenants set
forth in the agreement and hereinafter in this agreement, the undersigned
represents and agrees as follows:
 
  1. Pooling Requirements
 
  (a) The undersigned will not sell, transfer or otherwise dispose of, or
reduce his or its interest in or risk relating to, any AXENT Common Stock
issued to the undersigned pursuant to the Merger, or any AXENT Common Stock
issued to the undersigned upon exercise of any employee stock options, until
after such time as AXENT has published (within the meaning of Accounting
Series Release No. 130, as amended, of the Securities and Exchange Commission)
financial results covering at least 30 days of combined operations of the
Company and AXENT.
 
  (b) For a period commencing 30 days prior to the Effective Time of the
Merger and ending on the earlier of the Effective Time of the Merger or the
termination of the Merger Agreement, the undersigned will not sell, transfer
or otherwise dispose of, or reduce his or its interest in or risk relating to,
any shares of Raptor Common Stock presently owned or subsequently acquired by
the undersigned.
 
  2. Rule 145. The undersigned will not offer, sell, pledge, transfer or
otherwise dispose of any of the shares of AXENT Common Stock issued to the
undersigned in the Merger unless at such time either: (i) such transaction
shall be permitted pursuant to the provisions of Rule 145 under the Securities
Act of 1933 (the "Securities Act"), (ii) the undersigned shall have furnished
to AXENT an opinion of counsel, satisfactory to AXENT, to the effect that no
registration under the Securities Act would be required in connection with the
proposed offer, sale, pledge, transfer or other disposition; or (iii) a
registration statement under the Securities Act covering the proposed offer,
sale, pledge, transfer or other disposition shall be effective under the
Securities Act.
 
  3. Legend. The undersigned understands that all certificates representing
the AXENT Common Stock deliverable to the undersigned pursuant to the Merger
shall, until the occurrence of one of the events referred to in Section 2
above, bear a legend substantially as follows:
 
  "The shares represented by this certificate may not be offered, sold,
  pledged, transferred or otherwise disposed of except in accordance with the
  requirements of the Securities Act of 1933, as amended, and the other
  conditions specified in the Affiliates Agreement dated as of December 1,
  1997 between the holder of this certificate and AXENT Technologies, Inc., a
  copy of which Agreement may be inspected by the holder of the certificate
  at the offices of AXENT Technologies, Inc. or furnished by AXENT
  Technologies, Inc. to the holder of this certificate upon written request
  and without charge."
 
                                       1
<PAGE>
 
  AXENT, in its discretion, may cause stop transfer orders to be placed with
its transfer agent with respect to the certificates for the shares of AXENT
Common Stock which are required to bear the foregoing legend.
 
  4. Tax Matters. The undersigned has, and as of the Effective Time of the
Merger will have, no present plan or intent to engage in a sale, exchange,
transfer, pledge, disposition or any other transaction (including a
distribution by a partnership to its partners or by a corporation to its
shareholders) that results in a reduction in the risk of ownership
(collectively, a "Sale") with respect to more than 50% of the shares of AXENT
Common Stock to be acquired by the undersigned upon consummation of the
Merger. The undersigned is not aware of, or participating in, any present plan
or intention (a "Plan") on the part of Company stockholders to engage in Sales
of shares of AXENT Common Stock to be issued in the Merger such that the
aggregate fair market value, as of the Effective Time of the Merger, of the
shares subject to such Sales would exceed fifty percent (50%) of the aggregate
fair market value of all outstanding Raptor Common Stock immediately prior to
the Merger. For purposes of the preceding sentence, shares of Raptor Common
Stock (i) which are exchanged for cash in lieu of fractional shares of AXENT
Common Stock or (ii) with respect to which a pre-Merger Sale occurs in a
Related Transaction (as defined below), shall be considered to be shares of
Raptor Common Stock that are exchanged for AXENT Common Stock in the Merger
and then disposed of pursuant to a Plan. A Sale of AXENT Common Stock shall be
considered to have occurred pursuant to a Plan if, among other things, such
Sale occurs in a Related Transaction. For purposes of this Section, a "Related
Transaction" shall mean a transaction that is in contemplation of, or related
or pursuant to, the Merger or the Merger Agreement. If any of the
undersigned's representations in this section cease to be true at any time
prior to the Effective Time of the Merger, the undersigned will deliver to
each of AXENT and the Company, prior to the Effective Time of the Merger, a
written statement to that effect, signed by the undersigned.
 
  5. Miscellaneous.
 
  (a) This Agreement shall be governed by and construed in accordance with the
laws of the State of Delaware.
 
  (b) This Agreement shall be binding on the undersigned's successors and
assigns, including his heirs, executors and administrators.
 
  (c) This Agreement shall terminate and be of no further force and effect if
the Merger Agreement is terminated in accordance with its terms.
 
  The undersigned has carefully read this agreement and discussed its
requirements, to the extent the undersigned believed necessary, with its
counsel or counsel for AXENT.
 
                                          Very truly yours,

                         VOTING AND SUPPORT AGREEMENT
 
  Agreement dated as of December 1, 1997 between the shareholder identified on
Exhibit A hereto (the "Shareholder") and Axent Technologies, Inc., a Delaware
corporation ("Axent"). Capitalized terms used but not defined herein shall
have the meanings ascribed to such terms in the Merger Agreement (as defined
below).
 
  In consideration of the execution by Axent of the Agreement and Plan of
Merger dated as of December 1, 1997 (the "Merger Agreement") among Axent,
Axquisition Two, Inc., a Delaware corporation, and Raptor Systems, Inc., a
Delaware corporation ("Raptor"), and other good and valuable consideration,
receipt of which is hereby acknowledged, the Shareholder and Axent hereby
agree as follows:
 
  1. Representations, Warranties and Agreements of Shareholder. The
Shareholder hereby represents and warrants to, and agrees with, Axent as
follows:
 
    (a) Title. As of the date hereof, the Shareholder is the beneficial and
  registered owner of     shares (the "Shares") of common stock, $.01 par
  value per share ("Common Stock"), of Raptor. As of the date hereof, except
  as set forth on Exhibit A hereto, the Shareholder does not (i) beneficially
  own any shares of any class or series of capital stock of Raptor (other
  than the Shares) or any securities convertible into or exercisable for
  shares of any class or series of Raptor's capital stock or (ii) have any
  options or other rights to acquire any shares of any class or series of
  capital stock of Raptor or any securities convertible into or exercisable
  for shares of any class of Raptor's capital stock. Except as set forth in
  Exhibit B hereto, the Shareholder owns the Shares free and clear of any
  lien, mortgage, pledge, charge, security interest or any other encumbrance
  of any kind. The Shareholder covenants and agrees to comply with the pledge
  agreements and other loan documents relating to the pledges of certain of
  the Shares identified on Exhibit B and to otherwise take any action
  necessary to insure that the Shareholder can carry out the terms of this
  Agreement.
 
    (b) Right to Vote and to Transfer Shares. The Shareholder has full legal
  power, authority and right to vote all of the Shares in favor of approval
  and adoption of the Merger Agreement without the consent or approval of, or
  any other action on the part of, any other person or entity, except under
  applicable requirements, if any, of the Securities Exchange Act of 1934, as
  amended, and except where the failure to obtain such consent or approval
  could not prevent or delay the performance by such Shareholder of his
  obligations under this Agreement in any material respect. Without limiting
  the generality of the foregoing, except for this Agreement, Shareholder has
  not entered into any voting agreement or any other agreement with any
  person or entity with respect to any of the Shares, granted any person or
  entity any proxy (revocable or irrevocable) or power of attorney with
  respect to any of the Shares, deposited any of the Shares in a voting trust
  or entered into any arrangement or agreement with any person or entity
  limiting or affecting the Shareholder's ability to enter into this
  Agreement or legal power, authority or right to vote the Shares in favor of
  the approval and adoption of the Merger Agreement or any of the
  transactions contemplated by the Merger Agreement, and Shareholder will not
  take any such action after the date of this Agreement and prior to the
  Raptor shareholders meeting to vote on approval and adoption of the Merger
  Agreement, including any adjournment or postponement thereof (the "Raptor
  Shareholders Meeting"). This Agreement has been duly executed and delivered
  by the Shareholder and, assuming its due execution and delivery by Axent,
  constitutes a valid and binding agreement of the Shareholder.
 
  2. Representations and Warranties of Axent. Axent hereby represents and
warrants to the Shareholder that this Agreement (i) has been duly authorized
by all necessary corporate action, (iii) has been duly executed and delivered
by Axent and (iii) is a valid and binding agreement of Axent.
 
  3. Restriction on Transfer. The Shareholder agrees that (other than pursuant
to the Merger Agreement) it will not, and will not agree to, sell, assign,
dispose of, encumber, mortgage, hypothecate or otherwise transfer or encumber
(collectively, "Transfer") any of the Shares to any person or entity;
provided, however, that the
<PAGE>
 
Shareholder may enter into pledge agreements pledging any of the Shares as
collateral security under loan agreements, provided that (i) the lender under
each such loan agreement consents to this Agreement and fulfillment of the
terms thereof and (ii) the Shareholder covenants and agrees to comply with
each pledge agreement and other loan documents relating to pledges of Shares
thereunder and to otherwise take all action necessary to insure that the
Shareholder can carry out the terms of this Agreement.
 
  4. Agreement to Vote of Shareholder. The Shareholder, in his individual
capacity as a shareholder of Raptor only, hereby irrevocably and
unconditionally agrees to vote or to cause to be voted all of the Shares at
the Raptor Shareholders' Meeting and at any other annual or special meeting of
shareholders of Raptor where such matters arise (a) in favor of the approval
and adoption of the Merger Agreement and (b) against (i) approval of any
proposal made in opposition to or in competition with the Merger or any of the
other transactions contemplated by the Merger Agreement, (ii) any merger,
consolidation, sale of assets, business combination, share exchange,
reorganization or recapitalization of Raptor or any of its subsidiaries, with
or involving any party other than Axent or one of its subsidiaries, (iii) any
liquidation, dissolution or winding up of Raptor, (iv) any extraordinary
dividend by Raptor, (v) any change in the capital structure of Raptor (other
than pursuant to the Merger Agreement) and (vi) any other action that may
reasonably be expected to impede, interfere with, delay, postpone or attempt
to discourage the Merger or the other transactions contemplated by the Merger
Agreement or this Agreement or result in a breach of any of the covenants,
representations, warranties or other obligations or agreements of Raptor under
the Merger Agreement which would materially and adversely affect Raptor or its
ability to consummate the transactions contemplated by the Merger Agreement.
The Stockholder further agrees not to take or commit or agree to take any
action inconsistent with the foregoing.
 
  5. Action in Shareholder Capacity Only. The Shareholder signs solely in the
Shareholder's capacity as a record and beneficial owner of the Shares, and
nothing herein shall prohibit, prevent or preclude the Shareholder from
fulfilling his fiduciary duties as a director of Raptor, including without
limitation, voting or consenting as a director in favor of an Acquisition
Proposal (as defined in the Merger Agreement) or negotiating with respect to
an Acquisition Proposal in his capacity as an officer or director of Raptor.
 
  6. No Shopping. The Shareholder, in his individual capacity as a shareholder
of Raptor only, agrees not to, directly or indirectly, (i) solicit, initiate
or encourage (or authorize any person to solicit, initiate or encourage) any
inquiry, proposal or offer from any person relating to an Acquisition Proposal
or (ii) participate in any discussion or negotiations regarding, or furnish to
any other person any information with respect to, or otherwise cooperate in
any way with, or participate in, facilitate or encourage any effort or attempt
by any other person to do or seek any of the foregoing that constitutes, or
would reasonably be expected to lead to, an Acquisition Proposal; provided
that, notwithstanding the foregoing, the Shareholder shall not be prohibited
from taking any such actions as are required, based upon advice of counsel, to
comply with his fiduciary duties as an officer and/or director of Raptor to
the extent such actions are permitted under the Merger Agreement.
 
  7. Executed in Counterparts. This Agreement may be executed in counterparts
each of which shall be an original with the same effect as if the signatures
hereto and thereto were upon the same instrument.
 
  8. Specific Performance. The parties hereto agree that if for any reason the
Shareholder fails to perform any of his agreements or obligations under this
Agreement irreparable harm or injury to Axent would be caused for which money
damages would not be an adequate remedy. Accordingly, the Shareholder agrees
that, in seeking to enforce this Agreement against the Shareholder, Axent
shall be entitled to specific performance and injunctive and other equitable
relief in addition and without prejudice to any other rights or remedies,
whether at law or in equity, that Axent may have against the Shareholder for
any failure to perform any of its agreements or obligations under this
Agreement.
 
  9. Amendments; Termination.
 
    (a) This Agreement may not be modified, amended, altered or supplemented,
  except upon the execution and delivery of a written agreement executed by
  the parties hereto.
 
                                       2
<PAGE>
 
    (b) The provisions of this Agreement shall terminate upon the earlier to
  occur of the Effective Time or the termination of the Merger Agreement
  pursuant to Section 6.1 thereof.
 
    (c) For purposes of this Agreement, the term "Merger Agreement" includes
  the Merger Agreement, as the same may be modified or amended from time to
  time.
 
  10. Additional Shares. If, after the date hereof the Shareholder acquires
beneficial ownership of any shares of the capital stock of Raptor (any such
shares, "Additional Shares"), including, without limitation, upon exercise of
any option, warrant or right to acquire shares of capital stock or through any
stock dividend or stock split, the provisions of this Agreement (other than
those set forth in Section 1 (a)) applicable to the Shares shall be applicable
to such Additional Shares as if such Additional Shares had been Shares as of
the date hereof. The provisions of the immediately preceding sentence shall be
effective with respect to Additional Shares without action by any person or
entity immediately upon the acquisition by the Shareholder of beneficial
ownership of such Additional Shares.
 
  11. Action by Written Consent. If, in lieu of the Raptor Shareholders
Meeting, shareholder action in respect of the Merger Agreement or any of the
transactions contemplated by the Merger Agreement is taken by written consent,
the provisions of this Agreement imposing obligations in respect of or in
connection with the Raptor Shareholders Meeting shall apply mutatis mutandis
to such action by written consent.
 
  12. Successors and Assigns. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their
respective legal successors and permitted assigns; provided that no party may
assign, delegate or otherwise transfer any of its rights or obligations under
this Agreement without the consent of Axent (in the case of the Shareholder or
any of its permitted assigns) or the Shareholder (in the case of Axent or any
of its permitted assigns).
 
  13. Notices. All notices, requests, claims, demands and other communications
hereunder shall be deemed to have been duly given when delivered in person, by
facsimile, or by registered or certified mail (postage prepaid, return receipt
requested) to such party at its address set forth on the signature page
hereto.
 
  14. Severability. If any term or other provision of this Agreement is
determined to be invalid, illegal or incapable of being enforced by any rule
or law or public policy, all other conditions and provisions of this Agreement
shall nevertheless remain in full force and effect so long as the economic or
legal substance of the transactions contemplated hereby is not affected in any
manner materially adverse to any party. Upon such determination that any term
or provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible to the fullest
extent permitted by applicable law in an acceptable manner to the end that the

                         VOTING AND SUPPORT AGREEMENT
 
  Agreement dated as of December 1, 1997 between the shareholder identified on
Exhibit A hereto (the "Shareholder") and Raptor Systems, Inc., a Delaware
corporation ("Raptor"). Capitalized terms used but not defined herein shall
have the meanings ascribed to such terms in the Merger Agreement (as defined
below).
 
  In consideration of the execution by Raptor of the Agreement and Plan of
Merger dated as of December 1, 1997 (the "Merger Agreement") among Raptor,
Axquisition Two, Inc., a Delaware corporation, and Axent Technologies, Inc., a
Delaware corporation ("Axent"), and other good and valuable consideration,
receipt of which is hereby acknowledged, the Shareholder and Raptor hereby
agree as follows:
 
    1. Representations, Warranties and Agreements of Shareholder. The
  Shareholder hereby represents and warrants to, and agrees with, Raptor as
  follows:
 
      (a) Title. As of the date hereof, the Shareholder is the beneficial
    and registered owner of     shares (the "Shares") of common stock, $.02
    par value per share ("Common Stock"), of Axent. As of the date hereof,
    except as set forth on Exhibit A hereto, the Shareholder does not (i)
    beneficially own any shares of any class or series of capital stock of
    Axent (other than the Shares) or any securities convertible into or
    exercisable for shares of any class or series of Axent's capital stock
    or (ii) have any options or other rights to acquire any shares of any
    class or series of capital stock of Axent or any securities convertible
    into or exercisable for shares of any class of Axent's capital stock.
    Except as set forth in Exhibit B hereto, the Shareholder owns the
    Shares free and clear of any lien, mortgage, pledge, charge, security
    interest or any other encumbrance of any kind. The Shareholder
    covenants and agrees to comply with the pledge agreements and other
    loan documents relating to the pledges of certain of the Shares
    identified on Exhibit B and to otherwise take any action necessary to
    insure that the Shareholder can carry out the terms of this Agreement.
 
      (b) Right to Vote and to Transfer Shares. The Shareholder has full
    legal power, authority and right to vote all of the Shares in favor of
    approval and adoption of the Merger Agreement without the consent or
    approval of, or any other action on the part of, any other person or
    entity, except under applicable requirements, if any, of the Securities
    Exchange Act of 1934, as amended, and except where the failure to
    obtain such consent or approval could not prevent or delay the
    performance by such Shareholder of his obligations under this Agreement
    in any material respect. Without limiting the generality of the
    foregoing, except for this Agreement, Shareholder has not entered into
    any voting agreement or any other agreement with any person or entity
    with respect to any of the Shares, granted any person or entity any
    proxy (revocable or irrevocable) or power of attorney with respect to
    any of the Shares, deposited any of the Shares in a voting trust or
    entered into any arrangement or agreement with any person or entity
    limiting or affecting the Shareholder's ability to enter into this
    Agreement or legal power, authority or right to vote the Shares in
    favor of the approval and adoption of the Merger Agreement or any of
    the transactions contemplated by the Merger Agreement, and Shareholder
    will not take any such action after the date of this Agreement and
    prior to the Axent shareholders meeting to vote on approval and
    adoption of the Merger Agreement, including any adjournment or
    postponement thereof (the "Axent Shareholders Meeting"). This Agreement
    has been duly executed and delivered by the Shareholder and, assuming
    its due execution and delivery by Raptor, constitutes a valid and
    binding agreement of the Shareholder.
 
    2. Representations and Warranties of Raptor. Raptor hereby represents and
  warrants to the Shareholder that this Agreement (i) has been duly
  authorized by all necessary corporate action, (iii) has been duly executed
  and delivered by Raptor and (iii) is a valid and binding agreement of
  Raptor.
 
    3. Restriction on Transfer. The Shareholder agrees that it will not, and
  will not agree to, sell, assign, dispose of, encumber, mortgage,
  hypothecate or otherwise transfer or encumber (collectively, "Transfer")
  any of the Shares to any person or entity; provided, however, that the
  Shareholder may enter into pledge
<PAGE>
 
  agreements pledging any of the Shares as collateral security under loan
  agreements, provided that (i) the lender under each such loan agreement
  consents to this Agreement and fulfillment of the terms thereof and (ii)
  the Shareholder covenants and agrees to comply with each pledge agreement
  and other loan documents relating to pledges of Shares thereunder and to
  otherwise take all action necessary to insure that the Shareholder can
  carry out the terms of this Agreement.
 
    4. Agreement to Vote of Shareholder. The Shareholder, in his individual
  capacity as a shareholder of Axent only, hereby irrevocably and
  unconditionally agrees to vote or to cause to be voted all of the Shares at
  the Axent Shareholders' Meeting and at any other annual or special meeting
  of shareholders of Axent where such matters arise (a) in favor of the
  approval and adoption of the Merger Agreement and (b) against (i) approval
  of any proposal made in opposition to or in competition with the Merger or
  any of the other transactions contemplated by the Merger Agreement, (ii)
  any merger, consolidation, sale of assets, business combination, share
  exchange, reorganization or recapitalization of Axent or any of its
  subsidiaries, with or involving any party other than Raptor or one of its
  subsidiaries, (iii) any liquidation, dissolution or winding up of Axent,
  (iv) any extraordinary dividend by Axent, (v) any change in the capital
  structure of Axent (other than pursuant to the Merger Agreement) and (vi)
  any other action that may reasonably be expected to impede, interfere with,
  delay, postpone or attempt to discourage the Merger or the other
  transactions contemplated by the Merger Agreement or this Agreement or
  result in a breach of any of the covenants, representations, warranties or
  other obligations or agreements of Axent under the Merger Agreement which
  would materially and adversely affect Axent or its ability to consummate
  the transactions contemplated by the Merger Agreement. The Stockholder
  further agrees not to take or commit or agree to take any action
  inconsistent with the foregoing.
 
    5. Action in Shareholder Capacity Only. The Shareholder signs solely in
  the Shareholder's capacity as a record and beneficial owner of the Shares,
  and nothing herein shall prohibit, prevent or preclude the Shareholder from
  fulfilling his fiduciary duties as a director of Axent, including without
  limitation, voting or consenting as a director in favor of an Acquisition
  Proposal (as defined in the Merger Agreement) or negotiating with respect
  to an Acquisition Proposal in his capacity as an officer or director of
  Axent.
 
    6. No Shopping. The Shareholder, in his individual capacity as a
  shareholder of Axent only, agrees not to, directly or indirectly, (i)
  solicit, initiate or encourage (or authorize any person to solicit,
  initiate or encourage) any inquiry, proposal or offer from any person
  relating to an Acquisition Proposal or (ii) participate in any discussion
  or negotiations regarding, or furnish to any other person any information
  with respect to, or otherwise cooperate in any way with, or participate in,
  facilitate or encourage any effort or attempt by any other person to do or
  seek any of the foregoing that constitutes, or would reasonably be expected
  to lead to, an Acquisition Proposal; provided that, notwithstanding the
  foregoing, the Shareholder shall not be prohibited from taking any such
  actions as are required, based upon advice of counsel, to comply with his
  fiduciary duties as an officer and/or director of Axent to the extent such
  actions are permitted under the Merger Agreement.
 
    7. Executed in Counterparts. This Agreement may be executed in
  counterparts each of which shall be an original with the same effect as if
  the signatures hereto and thereto were upon the same instrument.
 
    8. Specific Performance. The parties hereto agree that if for any reason
  the Shareholder fails to perform any of his agreements or obligations under
  this Agreement irreparable harm or injury to Raptor would be caused for
  which money damages would not be an adequate remedy. Accordingly, the
  Shareholder agrees that, in seeking to enforce this Agreement against the
  Shareholder, Raptor shall be entitled to specific performance and
  injunctive and other equitable relief in addition and without prejudice to
  any other rights or remedies, whether at law or in equity, that Raptor may
  have against the Shareholder for any failure to perform any of its
  agreements or obligations under this Agreement.
 
    9. Amendments; Termination.
 
      (a) This Agreement may not be modified, amended, altered or
    supplemented, except upon the execution and delivery of a written
    agreement executed by the parties hereto.
 
                                       2
<PAGE>
 
      (b) The provisions of this Agreement shall terminate upon the earlier
    to occur of the Effective Time or the termination of the Merger
    Agreement pursuant to Section 6.1 thereof.
 
      (c) For purposes of this Agreement, the term "Merger Agreement"
    includes the Merger Agreement, as the same may be modified or amended
    from time to time.
 
    10. Additional Shares. If, after the date hereof the Shareholder acquires
  beneficial ownership of any shares of the capital stock of Axent (any such
  shares, "Additional Shares"), including, without limitation, upon exercise
  of any option, warrant or right to acquire shares of capital stock or
  through any stock dividend or stock split, the provisions of this Agreement
  (other than those set forth in Section 1 (a)) applicable to the Shares
  shall be applicable to such Additional Shares as if such Additional Shares
  had been Shares as of the date hereof. The provisions of the immediately
  preceding sentence shall be effective with respect to Additional Shares
  without action by any person or entity immediately upon the acquisition by
  the Shareholder of beneficial ownership of such Additional Shares.
 
    11. Action by Written Consent. If, in lieu of the Axent Shareholders
  Meeting, shareholder action in respect of the Merger Agreement or any of
  the transactions contemplated by the Merger Agreement is taken by written
  consent, the provisions of this Agreement imposing obligations in respect
  of or in connection with the Axent Shareholders Meeting shall apply mutatis
  mutandis to such action by written consent.
 
    12. Successors and Assigns. The provisions of this Agreement shall be
  binding upon and inure to the benefit of the parties hereto and their
  respective legal successors and permitted assigns; provided that no party
  may assign, delegate or otherwise transfer any of its rights or obligations
  under this Agreement without the consent of Raptor (in the case of the
  Shareholder or any of its permitted assigns) or the Shareholder (in the
  case of Raptor or any of its permitted assigns).
 
    13. Notices. All notices, requests, claims, demands and other
  communications hereunder shall be deemed to have been duly given when
  delivered in person, by facsimile, or by registered or certified mail
  (postage prepaid, return receipt requested) to such party at its address
  set forth on the signature page hereto.
 
    14. Severability. If any term or other provision of this Agreement is
  determined to be invalid, illegal or incapable of being enforced by any
  rule or law or public policy, all other conditions and provisions of this
  Agreement shall nevertheless remain in full force and effect so long as the
  economic or legal substance of the transactions contemplated hereby is not
  affected in any manner materially adverse to any party. Upon such
  determination that any term or provision is invalid, illegal or incapable
  of being enforced, the parties hereto shall negotiate in good faith to
  modify this Agreement so as to effect the original intent of the parties as
  closely as possible to the fullest extent permitted by applicable law in an
  acceptable manner to the end that the transactions contemplated hereby are
  fulfilled to the extent possible.
 
    15. Entire Agreement. This Agreement constitutes the entire agreement of
  the parties and supersedes all prior agreements and undertakings, both
  written and oral, between the parties, or any of them, with respect to the
  subject matter hereof.
 
    16. Governing Law; Jurisdiction and Venue. This Agreement shall be
  governed by and construed in accordance with the internal laws (and not the
  law of conflicts) of the State of Delaware. The parties hereto hereby
  irrevocably and unconditionally consent to submit to the exclusive
  jurisdiction of the courts of the State of Delaware and the United States
  of America located in the State of Delaware (the "Delaware Courts") for any

  contrary, the covenants and agreements set forth herein shall not prevent
  any of the Shareholders or their representatives or designees who are
  serving on the Board of Directors of Axent or who are officers of Axent
  from taking any action, subject to the applicable provisions of the Merger
  Agreement, while acting in such capacity as a director or officer of Axent.

                        STOCK OPTION EXCHANGE AGREEMENT
 
  This Exchange Agreement ("Agreement") is entered into this    day of    ,
19 , by and among Axent Technologies, Inc., a Delaware corporation ("Axent"),
Raptor Systems, Inc., a Delaware corporation ("Raptor"), and ("Grantee").
 
                                   Recitals
 
  Whereas, Grantee is the holder of one or more outstanding options ("Raptor
Option") pursuant to which Grantee is or, subject to a schedule of
exercisability (vesting) set forth therein, may become entitled to purchase a
specified number of shares of common stock of Raptor ("Raptor Shares") at a
specified exercise price per share, as set forth on Schedule A attached hereto
("Schedule A"); and
 
  Whereas, Axent has entered into a certain Agreement and Plan of
Reorganization and Merger with Raptor, dated December 1, 1997 ("Merger
Agreement"), pursuant to which all holders of outstanding options to purchase
Raptor Shares are to be offered in exchange therefor options to purchase the
number of shares of Axent common stock ("Axent Shares") equal to the number of
Raptor Shares which could be acquired upon the exercise of such Raptor Options
multiplied by the Exchange Ratio, at an exercise price per share equal to the
per share exercise price of such Raptor options divided by the Exchange Ratio,
all as such terms are defined in the Merger Agreement; and
 
  Whereas, Axent, Raptor, and Grantee mutually desire that, at the Effective
Time of the Merger under the Merger Agreement, each of Grantee's outstanding
Raptor Options be terminated in exchange for an option ("Axent Option") to
purchase Axent Shares on substantially the same original terms and conditions;
subject, however, to the formula noted in the immediately preceding paragraph
for determining the number of Axent Shares purchasable and the exercise price,
and subject to any acceleration of vesting as a result of the consummation of
the Merger,
 
  Now, Therefore, in consideration of the premises and of the mutual covenants
and undertakings hereinafter set forth, Axent, Raptor and Grantee hereby agree
as follows:
 
  1. The foregoing recitals are made a part of this Agreement and Grantee
represents and agrees that all Raptor Options heretofore granted to Grantee
and outstanding in whole or in part as of the date of this Agreement are
correctly described in Schedule A hereto. Words and terms used herein with
initial capital letters and not defined herein are used herein as defined in
the Merger Agreement.
 
  2. Grantee hereby accepts Axent's offer to exchange an Axent Option for each
Raptor Option held by Grantee and agrees that, at the Effective Time of the
Merger, each Raptor Option held by Grantee shall automatically be deemed
terminated and exchanged for an Axent Option for a number of Axent Shares
equal to the number of Raptor Shares covered by such Raptor Option multiplied
by the Exchange Ratio, at an exercise price per share equal to the per share
exercise price of such Raptor Option divided by the Exchange Ratio. The
vesting provisions, expiration date and terms and conditions of each such
Axent Option shall descend from and be the same as the vesting provisions,
expiration date and terms and conditions of the Raptor Option for which such
Axent Option is exchanged, after giving effect to any acceleration of vesting
for such Raptor Option as a result of the consummation of the Merger and
otherwise shall continue the original vesting, term and exercisability
provisions of the Raptor Option. The Axent Option shall not give the Grantee
any additional benefits that the Grantee did not have under the Raptor Option
other than the continuation of the term and exercisability thereof after the
consummation of the Merger in accordance with the original terms of such
Raptor Option. If the Raptor Option exchanged states that it is intended to be
(in whole or in part) an incentive stock option qualifying as such within the
meaning of the Internal Revenue Code of 1986, as amended, the Axent Option
issued in exchange therefor shall likewise so state, to the same extent.
 
                                       1
<PAGE>
 
  3. Grantee agrees to deliver to Raptor before the Effective Time or, if not
so delivered, then to Axent promptly after the Effective Time, at such address
or location as Axent may hereafter specify, the "Stock Option Agreement"
evidencing each Raptor Option held by Grantee and Axent agrees that, promptly
after receipt thereof (but not prior to the Effective Time), Axent will issue
and deliver to Grantee a written instrument evidencing each Axent Option for
which each such Raptor Option is being exchanged as provided herein. An Axent
Option shall not be exercisable until such instrument has been delivered to
Grantee. All Raptor Stock Option Agreements delivered to Raptor before the
Effective Time shall be delivered to Axent by Raptor at or promptly after the
Effective Time.
 
  4. This Agreement is conditioned upon the consummation of the Merger and if,
for whatever reason, the Merger Agreement shall be terminated or it shall be
established that the Merger will not be consummated (of which fact Raptor
shall notify Grantee), this Agreement shall automatically terminate and be of
no further force or effect and any Raptor Stock Option Agreement theretofore
delivered to Axent shall promptly be returned to Grantee.
 
  5. Grantee agrees that, at the Effective Time, any and all claims and rights
that Grantee ever had, now has or hereafter may have under all of Grantee's
Raptor Options against Raptor or its successors and assigns shall be deemed
released and extinguished, and thereafter Grantee's rights shall be only
against Axent, for the issuance and delivery of the Axent Option and the
performance of Axent's obligations thereunder.
 
  In Witness Whereof, the parties have executed this Agreement as of the date
first above written.

                     [FORM OF PIPER & MARBURY TAX OPINION]
 
AXENT Technologies, Inc.
2400 Research Boulevard
Suite 200
Rockville, MD 20850
 
  Re: Agreement and Plan of Merger dated [November ], 1997 Among
      [ABC Technologies, Inc.], Axquisition, Inc. and [Rook] Systems, Inc.
 
Ladies and Gentlemen:
 
  We have acted as counsel for AXENT Technologies, Inc., a Delaware
corporation (the "Company"), in connection with the proposed merger (the
"Merger") of Axquisition, Inc. ("Sub"), a Delaware corporation and a wholly
owned subsidiary of [ABC Technologies, Inc.], a Delaware corporation
("Parent"), with and into the Company, pursuant to an Agreement and Plan of
Merger dated November    , 1997 (the "Merger Agreement"), among Parent, Sub
and the Company, under which each issued and outstanding share of common stock
of the Company (other than shares owned directly by Parent or the Company)
will be exchanged for common stock of Parent.
 
  In that connection you have requested our opinion regarding the material
Federal income tax consequences of the Merger. In providing our opinion, we
have examined the Merger Agreement, the Joint Proxy Statement/Prospectus of
Parent and the Company dated    , 1997 (the "Proxy Statement/Prospectus"), and
such other documents and corporate records as we have deemed necessary or
appropriate for purposes of our opinion. In addition, we have assumed that (i)
the Merger will be consummated in accordance with the provisions of the Merger
Agreement and in the manner contemplated by the Proxy Statement/Prospectus,
(ii) the representations made to us by Parent and the Company in their
respective letters to us dated January    , 1998, and delivered to us for
purposes of this opinion are accurate and complete, (iii) the representations
made to us by certain shareholders of the Company in the Continuity of
Interest Letter dated January    , 1998, and delivered to us for purposes of
this opinion are accurate and complete and (iv) the opinion of Goodwin,
Procter & Hoar LLP, substantially identical in form to this opinion has been
delivered and not withdrawn.
 
  Based upon the foregoing, in our opinion, for Federal income tax purposes:
 
    (i) the Merger will constitute either (A) a reorganization within the
  meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Internal Revenue
  Code of 1986, as amended (the "Code"), or (B) if the Company is liquidated
  or merged upstream into Parent after the Merger and if such liquidation or
  merger is determined to be pursuant to the overall plan of reorganization
  contemplated by the Merger Agreement, a reorganization within the meaning
  of Section 368(a)(1)(A) or Section 368(a)(1)(C) of the Code depending upon
  whether the Company is merged upstream or liquidated after the Merger, and,
  in the case of either (A) or (B), Parent,
 
                                       1
<PAGE>
 
  Sub and the Company will each be a party to such reorganization within the
  meaning of Section 368(b) of the Code; and
 
    (ii) no gain or loss will be recognized by Parent, Sub or the Company in
  the Merger.
 
  The opinions expressed herein are based upon existing statutory, regulatory
and judicial authority, any of which may be changed at any time with
retroactive effect. In addition, our opinions are based solely on the
documents that we have examined, the additional information that we have
obtained, and the statements contained in the letters from Parent and the
Company referred to above, which we have assumed are true on the date on which
the Merger is consummated. Our opinions cannot be relied upon if any of the
facts pertinent to the Federal income tax treatment of the Merger stated in
such documents or in such additional information is, or later becomes,
inaccurate, or if any of the statements contained in the letters from Parent
and the Company and certain shareholders referred to above are, or later
become, inaccurate. Our opinions are limited to the tax matters specifically
covered hereby, and we have not been asked to address, nor have we addressed,
any other tax consequences of the Merger.
 
  This opinion has been delivered to you for the purpose of satisfying the
conditions set forth in Section 5.1(e) of the Agreement and is intended solely
for your benefit; it may not be relied upon for any other purpose or by any
other person or entity, and may not be made available to any other person or
entity without our prior written consent.

                            DATED DECEMBER 1, 1997,
                        AMONG AXENT TECHNOLOGIES, INC.
                AXQUISITION TWO. INC. AND RAPTOR SYSTEMS, INC.

provided to the "best knowledge" of Parent or the Company, as the case may be,
are accurate and correct as if made without such qualification, (iv) the

Ladies and Gentlemen:
 
  In connection with the opinion to be delivered by you regarding the
Agreement and Plan of Merger (the "Merger Agreement") dated December 1, 1997,
among Axent Technologies, Inc., a Delaware corporation ("Axent"), Axquisition
Two, Inc., a Delaware corporation and a wholly owned subsidiary of Axent
("Sub"), and Raptor Systems, Inc., a Delaware corporation ("Raptor"), I
certify that, after due inquiry and investigation, the facts relating to the
contemplated merger (the "Merger") of Sub with and into Raptor pursuant to the
Merger Agreement, as described in the Merger Agreement and in the
Prospectus/Joint Proxy Statement of Axent and Raptor dated       , 1997, are,
insofar as such facts pertain to Raptor, true, correct and complete in all
material respects. I further certify, after due inquiry and investigation and
after consultation with counsel and auditors as necessary regarding the
meaning of and factual support for the following representations, as follows:
 
    1. The formula set forth in the Merger Agreement pursuant to which each
  issued and outstanding share of common stock of Raptor ("Raptor Common
  Stock") (other than shares owned directly by Axent or Sub) will be
  exchanged for common stock of Axent ("Axent Common Stock") is the result of
  arm's length bargaining. Pursuant to such arm's length bargaining, the fair
  market value of the Axent Common Stock to be received by each Raptor
  stockholder in the Merger will be equal to the fair market value of the
  Raptor Common Stock surrendered by such stockholder in the Merger.
 
    2. Cash payments to be made to stockholders of Raptor in lieu of
  fractional shares of Axent Common Stock that would otherwise be issued to
  such stockholders in the Merger will be made for the purpose of saving
  Axent the expense and inconvenience of issuing and transferring fractional
  shares of Axent Common Stock, and do not represent separately bargained for
  consideration. The total cash consideration that will be paid in the
  transaction to the Raptor stockholders instead of issuing fractional shares
  of Axent Common Stock will not exceed 1% of the total consideration that
  will be issued to the Raptor stockholders in exchange for their shares of
  Raptor Common Stock. The fractional share interests will be aggregated, and
  no Raptor stockholder will receive cash in an amount greater than or equal
  to the value of one full share of Axent Common Stock.
 
    3. There is no plan or intention on the part of the stockholders of
  Raptor that own 5% or more of Raptor Common Stock, and Raptor knows of no
  plan or intention on the part of the remaining holders of Raptor Common
  Stock (in each case, a "Plan"), to engage in a sale, exchange, transfer,
  distribution, pledge, disposition or any other transaction that results in
  a reduction in the risk of ownership or a direct or indirect disposition (a
  "Sale") of a number of shares of Axent Common Stock received in the Merger
  that would reduce the ownership of Axent Common Stock by former holders of
  Raptor Common Stock to a number of shares having a value, as of immediately
  prior to the Merger, of less than 50% of the value of all of the shares of
  Raptor Common Stock as of such date. For purposes of this representation,
  shares of Raptor Common Stock (or the portion thereof) (i) with respect to
  which a Raptor shareholder receives consideration in the Merger other than
  Axent Common Stock (including, without limitation, cash in lieu of
  fractional shares of Axent Common Stock) and/or (ii) with respect to which
  a Sale occurs prior to and in contemplation of the Merger shall be
  considered outstanding shares of Raptor Common Stock exchanged for Axent
  Common Stock in the Merger and then disposed of pursuant to a Plan.
<PAGE>
 
    4. Immediately following the Merger, Raptor will hold at least 90 percent
  of the fair market value of its net assets and at least 70 percent of the
  fair market value of its gross assets, and at least 90 percent of the fair
  market value of Sub's net assets and at least 70 percent of the fair market
  value of Sub's gross assets held immediately prior to the Merger. For the
  purpose of determining the percentage of Raptor's net and gross assets held
  by Raptor immediately following the Merger, the following assets will be
  treated as property held by Raptor immediately prior to the Merger but not
  held by Raptor immediately subsequent to the Merger: (i) assets disposed of
  by Raptor prior to the Merger and in contemplation thereof (including,
  without limitation, any asset disposed of by Raptor, other than in the
  ordinary course of business, pursuant to a plan or intent existing during
  the period ending at the Closing Date and beginning with the commencement
  of negotiations (whether formal or informal) with Axent regarding the
  Merger), (ii) assets used by Raptor to pay expenses or liabilities incurred
  in connection with the Merger, and (iii) assets used to make distribution,
  redemption or other payments in respect of shares of Raptor Common Stock or
  rights to acquire such shares (including payments treated as such for tax
  purposes) that are made in contemplation of the Merger or related thereto.
 
    5. Raptor has no plan or intention to issue additional shares of Raptor
  Common Stock that would result in Axent losing control of Raptor within the
  meaning of Section 368(c)(1) of the Internal Revenue Code of 1986, as
  amended (the "Code").
 
    6. Axent, Sub, Raptor and the stockholders of Raptor will each pay their
  own expenses, if any, incurred in connection with the Merger, except that,
  pursuant to Section 7.10 of the Merger Agreement, Axent and Raptor will
  share certain reorganization expenses.
 
    7. There is no intercorporate indebtedness existing between Axent and
  Raptor or between Sub and Raptor that was issued, acquired or will be
  settled at a discount as a result of the Merger, and Axent will assume no
  liabilities of Raptor or any Raptor shareholder in connection with the
  Merger, except that Axent will assume liabilities of Raptor by operation of
  law in the event of a liquidation or merger of Raptor into Axent following
  the Merger.
 
    8. Pursuant to the Merger, Axent will acquire shares of Raptor Common
  Stock representing control of Raptor, as defined in Section 368(c)(1) of
  the Code, solely in exchange for voting stock of Axent. For purposes of
  this representation, Raptor Common Stock redeemed for cash or other
  property furnished by Raptor will be treated as outstanding Raptor Common
  Stock outstanding immediately prior to the Merger and will be considered to
  be acquired by Axent pursuant to the Merger. No liabilities of Raptor or
  the Raptor stockholders will be assumed by Axent, nor will any of the
  Raptor Common Stock be subject to any liabilities.
 
    9. At the time of the Merger, Raptor will not have outstanding any
  warrants, options, convertible securities or any other type of right
  pursuant to which any person could acquire stock of Raptor that, if
  exercised or converted, would affect Axent's acquisition or retention of
  control of Raptor, as defined in Section 368(c)(1) of the Code.
 
    10. Raptor is not an investment company as defined in Section
  368(a)(2)(F)(iii) and (iv) of the Code.
 
    11. Raptor is not under the jurisdiction of a court in a Title 11 or
  similar case within the meaning of Section 368(a)(3)(A) of the Code.
 
    12. As of the time of the Merger, the fair market value of the assets of
  Raptor will exceed the sum of its liabilities plus the liabilities, if any,
  to which its assets are subject.
 
    13. There will be no dissenters to the Merger.
 
    14. None of the compensation received by any stockholder-employee of
  Raptor represents separate consideration for, or allocable to, any of their
  Raptor Common Stock. None of the shares of Axent Common Stock received by
  any stockholders-employees of Raptor will be separate consideration for, or
  allocable to, any employment agreement. The compensation paid to any
  stockholder-employees will be for services actually rendered and will be
  commensurate with amounts paid to third parties bargaining at arm's length
  for similar services.
 
 
                                       4
<PAGE>
 
    15. Raptor will not take, and Raptor is not aware of any plan or
  intention of Raptor stockholders to take, any position on any Federal,
  state or local income or franchise tax return, or take any other action or
  reporting position, that is inconsistent with the treatment of the Merger
  as a reorganization within the meaning of Sections 368(a)(1)(A) and
  368(a)(2)(E) of the Code (or, in the event of a merger or liquidation of
  Raptor into Axent following the Merger and pursuant to the overall plan of
  reorganization, as a reorganization within the meaning of Section
  368(a)(1)(A) or Section 368(a)(1)(C) of the Code, depending on whether
  Raptor is merged or liquidated into Axent or with the representations made
  herein.
 
  16.  The Merger Agreement represents the entire understanding of Axent, Sub
  and Raptor with respect to the Merger.
 
  I understand that you will be relying upon the representations set forth
herein for purpose of rendering your opinion regarding the Federal income
consequences of the Merger.

insofar as such facts pertain to Axent and Sub, true, correct and complete in
all material respects. I further certify, after due inquiry and investigation
and after consultation with counsel and auditors as necessary regarding the
meaning of and factual support for the following representations, as follows:
 
    1. The formula set forth in the Merger Agreement pursuant to which each
  issued and outstanding share of common stock of Raptor ("Raptor Common
  Stock") (other than shares owned directly by Axent or Sub) will be

  a Sale occurs prior to and in contemplation of the Merger shall be
  considered outstanding shares of Raptor Common Stock exchanged for Axent
  Common Stock in the Merger and then disposed of pursuant to a Plan.
<PAGE>
 
    4. Immediately following the Merger, Raptor will hold a least 90 percent
  of the fair market value of its net assets and at lease 70 percent of the
  fair market value of its gross assets, and at least 90 percent of the fair
  market value of Sub's net assets and at least 70 percent of the fair market
  value of Sub's gross assets held immediately prior to the Merger. For the
  purpose of determining the percentage of Raptor's net and gross assets held
  by Raptor immediately following the Merger, the following assets will be
  treated as property held by Raptor immediately prior to the Merger but not
  held by Raptor immediately subsequent to the Merger: (i) assets disposed of
  by Raptor prior to the Merger and in contemplation thereof (including,
  without limitation, any asset disposed of by Raptor, other than in the
  ordinary course of business, pursuant to a plan or intent existing during
  the period ending at the Closing Date and beginning with the commencement
  of negotiations (whether formal or informal) with Axent regarding the
  Merger), (ii) assets used by Raptor to pay expenses or liabilities incurred
  in connection with the Merger, and (iii) assets used to make distribution,
  redemption or other payments in respect of shares of Raptor Common Stock or
  rights to acquire such shares (including payments treated as such for tax
  purpose) that are made in contemplation of the Merger or related thereto.
 
    5. Prior to the Merger, Axent will be in control of Sub within the
  meaning of Section 368(c)(1) of the Internal Revenue Code of 1986, as
  amended ( the "Code"). Axent has no plan or intention to cause Raptor to
  issue additional shares of stock after the Merger that would result in
  Axent losing control of Raptor within the meaning of Section 368(c)(1) of
  the Code.
 
    6. Except with respect to fractional share interests as set forth in
  Section 1.8 of the Merger Agreement, Axent has no plan or intention to
  reacquire any of the Axent Common Stock issued in the transaction.
 
    7. Except as set forth in paragraph 22 below, Axent has no plan or
  intention to liquidate Raptor, to merge Raptor with and into another
  corporation; to sell, distribute or otherwise dispose of the stock of
  Raptor; or to cause Raptor to sell or otherwise dispose of any of its
  assets or of any of the assets acquired from Sub in the Merger, except for
  (i) dispositions made in the ordinary course of business, (ii) transfers of
  assets to a corporation controlled by Raptor or (iii) payments of expenses
  incurred by Raptor pursuant to the Merger (including payments made with
  respect to fractional shares).
 
    8. Sub is a corporation newly formed for the purpose of participating in
  the Merger and at no time prior to the Merger has had assets or business
  operations. Sub will have no liabilities assumed by Raptor, and will not
  transfer to Raptor any assets subject to liabilities, in the Merger.
 
    9. Following the Merger, Raptor will continue its historic business or
  will use a significant portion of its historic business assets in a
  business, or Raptor will be liquidated or merged into Axent and Axent will
  continue to conduct the historic business of Raptor.
 
    10. Axent, Sub, Raptor and the stockholders of Raptor will each pay their
  own expenses, if any, incurred in connection with the Merger, except that,
  pursuant to Section 7.10 of the Merger Agreement, Axent and Raptor will
  share certain reorganization expenses.
 
    11. There is no intercorporate indebtedness existing between Axent and
  Raptor or between Sub and Raptor that was issued, acquired or will be
  settled at a discount as a result of the Merger, and Axent will assume no
  liabilities of Raptor or any Raptor shareholder in connection with the
  Merger, except that Axent will assume liabilities of Raptor by operation of
  law in the event of a liquidation or merger of Raptor into Axent described
  in paragraph 22.
 
    12. Pursuant to the Merger, Axent will acquire shares of Raptor Common
  Stock representing control of Raptor, as defined in Section 368(c)(1) of
  the Code, solely in exchange for voting stock of Axent. For purposes of
  this representation, Raptor Common Stock redeemed for cash or other
  property furnished by Raptor will be treated as outstanding Raptor Common
  Stock outstanding immediately prior to the Merger and will be considered to
  be acquired by Axent pursuant to the Merger. No liabilities of Raptor or
  the Raptor shareholders will be assumed by Axent, nor will any of the
  Raptor Common Stock be subject to any liabilities. No "poison pill" or
  similar rights will be associated with Axent Common Stock on or prior to
  the Closing Date.
 
    13. Neither Axent nor any current or former subsidiary of Axent owns, or
  has owned during the past five years, directly or indirectly, any shares of
  the stock of Raptor or the right to acquire or vote any such
 
                                       7

  shares (except as such rights are granted in the Merger Agreement). Except
  in the Merger, neither Axent nor Sub (nor any other subsidiary of Axent)
  has acquired or will acquire any shares of Raptor Common Stock.
 
    14. Neither Axent nor Sub is an investment company as defined in Section
  368(a)(2)(F)(iii) and (iv) of the Code.
 
    15. Neither Axent nor Sub is under the jurisdiction of a court in a Title
  11 or similar case within the meaning of Section 368(a)(3)(A) of the Code.
 
    16. There will be no dissenters to the Merger.
 
    17. Neither Axent nor Sub will take, and Axent is not aware of any plan
  or intention of Axent stockholders to take, any position on any Federal,
  state or local income or franchise tax return, or take any other action or
  reporting position, that is inconsistent with the treatment of the Merger
  as a reorganization within the meaning of Sections 368(a)(1)(A) and
  368(a)(2)(E) of the Code (or, in the event of a merger or liquidation of
  Raptor into Axent as described in paragraph 22 pursuant to the overall plan
  of reorganization, as a reorganization within the meaning of Section
  368(a)(1)(A) or 368(a)(1)(C) of the Code, depending on whether Raptor is
  merged or liquidated into Axent) or with the representations made herein.
 
    18. None of the compensation received by any stockholder-employee of
  Raptor represents separate consideration for, or allocable to, any of their
  Raptor Common Stock. None of the shares of Axent Common Stock received by
  any stockholders-employees of Raptor will be separate consideration for, or
  allocable to, any employment agreement. The compensation paid to any
  stockholder-employees will be for services actually rendered and will be
  commensurate with amounts paid to third parties bargaining at arm's length
  for similar services.
 
    19. No shares of Sub have been or will be used as consideration or issued
  to stockholders of Raptor pursuant to the Merger.
 
    20. The Merger Agreement represents the entire understanding of Axent,
  Sub and Raptor with respect to the Merger.
 
    21. The Merger is being undertaken for the purposes of enhancing the
  business of Axent and for other good business purposes of Axent.
    22. On some date following the Merger, Axent might merge Raptor into
  Axent, or liquidate Raptor into Axent in a transaction described in Section
  332 of the Code. If such merger or liquidation occurs:
 
      a. Axent will acquire at least 90 percent of the fair market value of
    the net assets and at least 70 percent of the fair market value of the
    gross assets held by Raptor immediately prior to the Merger. The
    principles set forth in paragraph 4 shall apply for the purpose of
    determining the percentage of Raptor's net and gross asserts held by
    Raptor immediately following the Merger.
 
      b. Axent will have no plan or intention to sell or otherwise dispose
    of any of the assets of Raptor acquired in the merger or liquidation,
    as the case may be, except for (i) dispositions made in the ordinary
    course of business, (ii) transfers described in Section 368(a)(2)(C) of
    the Code or (iii) payments of expenses incurred by Raptor pursuant to
    the Merger.
 
      c. The liabilities of Raptor to be assumed by Axent and the
    liabilities to which the transferred assets of Raptor will be subject
    will have been incurred by Raptor in the ordinary course of its
    business.
 
      d. Following the merger or liquidation, as the case may be, Axent
    will continue the historic business of Raptor or use a significant
    portion of Raptor's historic business assets in a business.
 
  I understand that you will be relying upon the representations set forth
herein for purposes of rendering your opinion regarding the Federal income tax
consequences of the Merger.

CONFIDENTIAL
 
Board of Directors
AXENT Technologies, Inc.
2400 Research Blvd.
Rockville, MD 20850
 
Dear Members of the Board:
 
  We understand that AXENT Technologies, Inc. ("AXENT"), Axquisition, Inc., a
wholly owned subsidiary of AXENT, (the "Transitory Subsidiary") and Raptor
Systems, Inc. ("Raptor") propose to enter into an Agreement and Plan of Merger
(the "Agreement") pursuant to which, through the merger of the Transitory
Subsidiary with and into Raptor (the "Merger"), each share of Raptor common
stock, $0.01 par value per share ("Raptor Common Stock"), shall be converted
into the right to receive 0.8000 shares (the "Exchange Ratio") of AXENT common
stock, $0.02 par value per share ("AXENT Common Stock"). The transaction is
intended to be a tax-free reorganization within the meaning of section 368(a)
of the United States Internal Revenue Code of 1986, as amended, and to be
accounted for as a pooling of interests pursuant to Opinion No. 16 of the
Accounting Principles Board. The terms and conditions of the above described
Merger are more fully detailed in the Agreement.
 
  You have requested our opinion as to whether the Exchange Ratio is fair,
from a financial point of view, to AXENT shareholders.
 
  Broadview Associates focuses on providing merger and acquisition advisory
services to information technology ("IT") companies. In this capacity, we are
continually engaged in valuing such businesses, and we maintain an extensive
database of IT mergers and acquisitions for comparative purposes. We are
currently acting as financial advisor to AXENT's Board of Directors and will
receive a fee from AXENT upon the successful conclusion of the Merger.
 
  In rendering our opinion, we have, among other things:
 
   (1) reviewed the terms of the Agreement and the associated exhibits
       thereto in the form of the draft dated November 26, 1997 furnished to
       us by Piper & Marbury on November 26, 1997 (which, for the purposes of
       this opinion, we have assumed, with your permission, to be identical
       in all material respects to the agreement to be executed);
 
   (2) reviewed Raptor's annual report and Form 10-K for the fiscal year
       ended December 31, 1996 which included results for the fiscal years
       ended December 31, 1995 and 1996, including the audited financial
       statements included therein, and Raptor's Form 10-Q for the nine
       months ended September 30, 1997, including the unaudited financial
       statements included therein;
 
   (3) reviewed certain internal financial and operating information,
       including certain projections, relating to Raptor prepared by Raptor
       management;
 
   (4) participated in discussions with Raptor management concerning the
       operations, business strategy, financial performance and prospects for
       Raptor;
 
   (5) reviewed the recent reported closing prices and trading activity for
       Raptor Common Stock;
 
   (6) compared certain aspects of the financial performance of Raptor with
       public companies we deemed comparable;
<PAGE>
 
    (7) analyzed available information, both public and private, concerning
        other mergers and acquisitions we believe to be comparable in whole
        or in part to the Merger;
 
    (8) reviewed AXENT's annual report and Form 10-K for the fiscal year
        ended December 31, 1996 which included results for the fiscal years
        ended December 31, 1995 and 1996, including the audited financial
        statements included therein, and AXENT's Form 10-Q for the nine
        months ended September 30, 1997, including the unaudited financial
        statements included therein;
 
    (9) participated in discussions with AXENT management concerning the
        operations, business strategy, financial performance and prospects
        for AXENT;
 
   (10) reviewed the recent reported closing prices and trading activity for
        AXENT Common Stock;
 
   (11) discussed with AXENT management its view of the strategic rationale
        for the Merger;
 
   (12) compared certain aspects of the financial performance of AXENT with
        public companies we deemed comparable;
 
   (13) considered the total number of shares of AXENT Common Stock
        outstanding and the average weekly trading volume of AXENT Common
        Stock;
 
   (14) reviewed recent equity analyst reports covering AXENT and Raptor;
 
   (15) analyzed the anticipated effect of the Merger on the future financial
        performance of the consolidated entity;
 
   (16) assisted in negotiations and discussions related to the Merger among
        AXENT, Raptor and their financial and legal advisors; and
 
   (17) conducted other financial studies, analyses and investigations as we
        deemed appropriate for purposes of this opinion.
 
  In rendering our opinion, we have relied, without independent verification,
on the accuracy and completeness of all the financial and other information
(including without limitation the representations and warranties contained in
the Agreement) that was publicly available or furnished to us by AXENT, Raptor
or Raptor's financial advisor. With respect to the financial projections
examined by us, we have assumed that they were reasonably prepared and
reflected the best available estimates and good faith judgments of the
management of Raptor as to the future performance of Raptor. We have neither
made nor obtained an independent appraisal or valuation of any of Raptor's
assets.
 
  Based upon and subject to the foregoing, we are of the opinion that the
Exchange Ratio is fair, from a financial point of view, to AXENT shareholders.
 
  For purposes of this opinion, we have assumed that neither AXENT nor Raptor
is currently involved in any material transaction, including financings,
recapitalizations, mergers, acquisitions and dispositions, other than the
Merger and those activities undertaken in the ordinary course of conducting
their respective businesses. Our opinion is necessarily based upon market,
economic, financial and other conditions as they exist and can be evaluated as
of the date of this opinion, and any change in such conditions would require a
reevaluation of this opinion. We express no opinion as to the price at which
AXENT Common Stock will trade subsequent to the Effective Time (as defined in
the Agreement).
 
  This opinion speaks only as of the date hereof. It is understood that this
opinion is for the information of the Board of Directors of AXENT in
connection with its consideration of the Merger and does not constitute a
recommendation to any AXENT shareholder as to how such shareholder should vote
on the Merger. Broadview Associates does not believe that any other person
other than the Board of Directors of AXENT has the legal right under state law
to rely on this opinion, and, in the absence of any governing precedents, we
would resist any assertion otherwise by any such person. This opinion may not
be published or referred to, in whole or part,
 
                                       2

without our prior written permission, which shall not be unreasonably
withheld. Broadview Associates hereby consents to references to and the
inclusion of this opinion in its entirety in the Proxy Statement/Prospectus to
be distributed to AXENT shareholders in connection with the Merger.
 
                                          Sincerely,
 
                                              /s/ Broadview Associates llc

Board of Directors
Raptor Systems, Inc.
69 Hickory Drive
Waltham, MA 02154
 
Members of the Board:
 
  We understand that Raptor Systems, Inc., a Delaware corporation ("Seller"),
and AXENT Technologies, Inc., a Delaware Corporation ("Buyer"), have entered
into a Merger Agreement to be dated December 1, 1997 (the "Merger Agreement"),
pursuant to which Seller will be merged with and into Buyer, which will be the
surviving entity (the "Merger"). Pursuant to the Merger, as more fully
described in the Merger Agreement and as further described to us by management
of Seller, we understand that each outstanding share of the common stock,
$0.01 par value per share ("Seller Common Stock"), of Seller will be converted
into and exchangeable for 0.8 shares of the common stock, $0.02 par value per
share ("Buyer Common Stock"), of Buyer, subject to certain adjustments (the
"Consideration"). The terms and conditions of the Merger are set forth in more
detail in the Merger Agreement.
 
  You have asked for our opinion as investment bankers as to whether the
Consideration to be received by the shareholders of Seller pursuant to the
Merger is fair to such shareholders from a financial point of view, as of the
date hereof.
 
  In connection with our opinion, we have, among other things: (i) reviewed
certain publicly available financial and other data with respect to Seller and
Buyer, including the consolidated financial statements for recent years and
interim periods to September 1997 and certain other relevant financial and
operating data relating to Seller and Buyer made available to us from
published sources and from the internal records of Seller and Buyer; (ii)
reviewed the financial terms and conditions of the Merger Agreement; (iii)
reviewed certain publicly available information concerning the trading of, and
the trading market for, Seller Common Stock and Buyer Common Stock; (iv)
compared Seller and Buyer from a financial point of view with certain other
companies in the software industry which we deemed to be relevant; (v)
considered the financial terms, to the extent publicly available, of selected
recent business combinations of companies in the software industry which we
deemed to be comparable, in whole or in part, to the Merger; (vi) reviewed the
premiums paid of selected recent merger of equals combinations which we deemed
to be comparable in whole or in part, to the merger; (vii) reviewed the
financial contribution each company is making to the combined company and
compared that contribution to the percentage ownership each company's
shareholders will hold in the combined company after the transaction closes;
(viii) reviewed and discussed with representatives of the management of Seller
and Buyer certain information of a business and financial nature regarding
Seller and Buyer, furnished to us by them, including financial forecasts and
related assumptions of Seller and Buyer; and (ix) performed such other
analyses and examinations as we have deemed appropriate.
 
  In connection with our review, we have not assumed any obligation
independently to verify the foregoing information and have relied on its being
accurate and complete in all material respects. With respect to the financial
forecasts for Seller and Buyer provided to us by their respective managements,
upon their advice and with your consent we have assumed for purposes of our
opinion that the forecasts have been reasonably prepared on bases reflecting
the best available estimates and judgments of their respective managements at
the time of preparation as to the future financial performance of Seller and
Buyer and that they provide a reasonable basis upon which we can form our
opinion. With respect to the forecasts for Buyer provided to us by its
management, for purposes of our analyses we have assumed that they provide a
reasonable basis upon which we can form our opinions. We have also assumed
that there have been no material changes in Seller's or Buyer's assets,
financial condition, results of operations, business or prospects since the
respective dates of their last financial statements
<PAGE>
 
made available to us. We have relied on advice of counsel and independent
accountants to Seller as to all legal and financial reporting matters with
respect to Seller, the Merger and the Merger Agreement. We have assumed that
the Merger will be consummated in a manner that complies in all respects with
the applicable provisions of the Securities Act of 1933, as amended (the
"Securities Act"), the Securities Exchange Act of 1934 and all other
applicable federal and state statutes, rules and regulations. In addition, we
have not assumed responsibility for making an independent evaluation,
appraisal or physical inspection of any of the assets or liabilities
(contingent or otherwise) of Seller or Buyer, nor have we been furnished with
any such appraisals. You have informed us, and we have assumed, that the
Merger will be recorded as a pooling of interests under generally accepted
accounting principles. Finally, our opinion is based on economic, monetary,
market and other conditions as in effect on, and the information made
available to us as of, the date hereof. Accordingly, although subsequent
developments may affect this opinion, we have not assumed any obligation to
update, revise or reaffirm this opinion.
 
  We have further assumed with your consent that the Merger will be
consummated in accordance with the terms described in the Merger Agreement,
without any further amendments thereto, and without waiver by Seller of any of
the conditions to its obligations thereunder.
 
  We have acted as financial advisor to Seller in connection with the Merger
and will receive a fee for our services, including rendering this opinion, a
significant portion of which is contingent upon the consummation of the
Merger. In the ordinary course of our business, we actively trade the equity
securities of Seller and Buyer for our own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities. We have also acted as an underwriter in connection with
offerings of securities of Seller and performed various investment banking
services for Seller and Buyer.
 
  Based upon the foregoing and in reliance thereon, it is our opinion as
investment bankers that the Consideration to be received by the shareholders
of Seller pursuant to the Merger is fair to such shareholders from a financial
point of view, as of the date hereof.
 
  We are not expressing an opinion regarding the price at which the Buyer
Common Stock may trade at any future time. The Consideration to be received by
the shareholders of Seller pursuant to the Merger is based upon a fixed
exchange ratio and, accordingly, the market value of the Consideration may
vary significantly.
 
  This opinion is directed to the Board of Directors of Seller in its
consideration of the Merger and is not a recommendation to any shareholder as
to how such shareholder should vote with respect to the Merger. Further, this
opinion addresses only the financial fairness of the Consideration to the
shareholders and does not address the relative merits of the Merger and any
alternatives to the Merger, Seller's underlying decision to proceed with or
effect the Merger, or any other aspect of the Merger. This opinion may not be
used or referred to by Seller, or quoted or disclosed to any person in any
manner, without our prior written consent, which consent is hereby given to
the inclusion of this opinion in any proxy statement or prospectus or the
Joint Proxy Statement/Prospectus filed with the Securities and Exchange
Commission in connection with the Merger. In furnishing this opinion, we do
not admit that we are experts within the meaning of the term "experts" as used
in the Securities Act and the rules and regulations promulgated thereunder,
nor do we admit that this opinion constitutes a report or valuation within the
meaning of Section 11 of the Securities Act.
 
                                          Very truly yours,
 

                                            /s/ NationsBanc Montgomery

                           AXENT TECHNOLOGIES, INC.
                       1998 EMPLOYEE STOCK PURCHASE PLAN
 
  The purpose of this Plan is to provide eligible employees of AXENT
Technologies, Inc. (the "Company") and certain of its subsidiaries with
opportunities to purchase, through payroll deductions, shares of the Company's
Common Stock, $.02 par value (the "Common Stock"). The Plan is intended to
benefit the Company by increasing the employees' interest in the Company's
growth and success and encouraging employees to remain in the employ of the
Company or its participating subsidiaries. The Plan is intended to constitute
an "employee stock purchase plan" within the meaning of Section 423 of the
Internal Revenue Code of 1986, as amended (the "Code"), and shall be so
applied and interpreted.
 
  1. Shares Subject to the Plan. Subject to adjustment as provided herein, the
aggregate number of shares of Common Stock that may be made available for
purchase by participating employees under the Plan is 500,000. The shares
issuable under the Plan may, in the discretion of the Board of Directors of
the Company (the "Board"), be authorized but unissued shares of Common Stock,
shares purchased on the open market, or shares from any other proper source.
 
  2. Administration. The Plan will be administered by the Company's Board of
Directors or by a committee appointed by the Board (the "Committee"). The
Board or the Committee has authority to make rules and regulations for the
administration of the Plan and its interpretation and decisions with regard
thereto will be final and conclusive. No member of the Board or the Committee
shall be liable for any action or determination made in good faith with
respect to the Plan or any Option granted hereunder.
 
  3. Eligibility. All employees of the Company, including directors who are
employees, and all employees of any subsidiary of the Company (as defined in
Section 424(f) of the Code), now or hereafter existing, that is designated by
the Board or the Committee from time to time as a participating employer under
the Plan (a "Designated Subsidiary"), are eligible to participate in any
Offering (as defined below) to purchase Common Stock under the Plan, subject
to such further eligibility requirements as may be specified by the Board or
Committee consistent with Section 423 of the Code.
 
  The Board or Committee at any time, if it deems it advisable to do so, may
terminate the participation of the employees of a particular Designated
Subsidiary.
 
  4. Participation. An eligible employee may become a participating employee
in the Plan by completing an election to participate in the Plan on a form
provided by the Committee and submitting that form to the appropriate payroll
location for such employee in accordance with such rules as may be established
by the Committee from time to time. The form will authorize a regular payroll
deduction from the Compensation (as defined below) received by the
participating employee during the Offering Period (as defined below) and will
authorize the purchase of shares of Common Stock for the participating
employee's account in accordance with the terms of the Plan.
 
  Enrollment will become effective upon the first day of the first Offering
Period that commences after the Company's receipt of the form, but not before
April 1, 1998. Unless an employee files a new form or withdraws from the Plan,
the participating employee's deductions and purchases will continue at the
same rate for future Offering Periods under the Plan as long as the Plan
remains in effect and the employee remains eligible to participate.
 
  The term "Compensation" means the amount of taxable income reportable for
federal income tax purposes on the employee's Federal Income Tax Withholding
Statement, excluding overtime, shift premium, incentive or bonus awards,
allowances and reimbursements for expenses such as relocation allowances or
travel expenses, income or gains on the exercise of Company stock options or
stock appreciation rights, and similar items,
<PAGE>
 
whether or not shown on the employee's Federal Income Tax Withholding
Statement, but including sales commissions or royalty payments to the extent
determined by the Board or the Committee. "Compensation" shall be determined
before reductions for any contributions to any plan maintained by the Company
and described in Section 401(k) or Section 125 of the Code.
 
  5. Payroll Deductions; Withdrawals From Accounts.
 
  (a) The Company will maintain payroll deduction accounts for all
participating employees. With respect to any Offering Period under this Plan,
an eligible employee may authorize a payroll deduction in any whole number
percentage up to a maximum of 10% of the Compensation he or she receives
during the Offering Period or such shorter period during which deductions from
payroll are made.
 
  (b) An employee may not increase or decrease his payroll deduction during
any Offering Period, but may increase or decrease his payroll deduction with
respect to a subsequent Offering Period by filing a new election form prior to
such date and in accordance with such rules as may be established by the
Committee from time to time.
 
  (c) Unless determined otherwise by the Committee, an employee may on any one
occasion during an Offering Period and for any reason withdraw all or part of
the balance accumulated in the employee's payroll deduction account. Any such
withdrawal must be effected prior to the close of business on the day
immediately preceding the last Trading Day (as defined below) of the Offering
Period by delivering a written notice of withdrawal to the appropriate payroll
location for such employee. If the employee withdraws all of such balance, the
employee will thereby withdraw from participation in the Offering and may not
begin participation again during the remainder of the Offering Period. Any
employee withdrawing all or part of such balance may participate in any
subsequent Offering Period in accordance with terms and conditions established
by the Committee.
 
  6. Interest. Interest will not be paid on any employee payroll deduction
accounts, except to the extent that the Board or the Committee, in its
discretion, elects to credit such accounts with interest at such per annum
rate as it may from time to time determine.
 
  7. Offering Periods. Options granted pursuant to the Plan ("Offerings") may
be exercised during an offering period which will begin on the first day on
which the National Association of Securities Dealers Automated Quotation
("Nasdaq") system is open for trading ("Trading Day") on or after January 1 of
each year or such other date specified by the Committee and will terminate on
the last Trading Day of a period specified by the Committee (each such period
referred to herein as an "Offering Period"). The first Offering Period under
the Plan shall commence at such time as the Committee determines, but no
earlier than January 1, 1998. The duration of an Offering Period shall be
determined by the Committee, in its discretion, prior to the deadline for
submission of employee election forms for such Offering Period; provided,
however, that no Offering Period shall have a duration in excess of 27 months.
Unless determined otherwise by the Committee, subsequent Offering Periods of
equal duration shall follow consecutively thereafter, each commencing on the
first Trading Day occurring immediately after the expiration of the preceding
Offering Period.
 
  8. Rights to Purchase Common Stock; Purchase Price.
 
  Options to purchase shares of Common Stock will be deemed granted (each, an
"Option") to participating employees as of the first Trading Day of each
Offering Period. Each Option shall represent a right to purchase on the last
Trading Day of such Offering Period, at the Purchase Price hereinafter
provided for, whole shares of Common Stock reserved for purposes of this Plan
up to a maximum determined by dividing 10% of such employee's projected
Compensation for the Offering Period by 85% of the Fair Market Value (as
defined below) of the Common Stock on the first Trading Day of such Offering
Period. The purchase price of each share of Common Stock (the "Purchase
Price") during an Offering Period shall be determined by the Committee, in its
discretion, prior to the deadline for submission of employee election forms
for such Offering Period; provided, however, that the Purchase Price for an
Offering Period shall never be less than the lesser of 85 percent of the
 
                                       2
<PAGE>
 
Fair Market Value of the Common Stock on the (i) first Trading Day of the
Offering Period or (ii) last Trading Day of such Offering Period.
 
  For purposes of the Plan, "Fair Market Value" means the closing sale price
per share of Common Stock as reflected on the principal consolidated
transaction reporting system for securities listed on any national securities
exchange or other market quotation system on which the Common Stock may be
principally listed or quoted or, if there are no transactions on a Trading
Day, then such closing price for the preceding Trading Day upon which
transactions occurred.
 
  No employee may be granted an Option hereunder if such employee, immediately
after the Option is granted, owns 5% or more of the total combined voting
power or value of the stock of the Company or any subsidiary. For purposes of
the preceding sentence, the attribution rules of Section 424(d) of the Code
will apply in determining the stock ownership of an employee, and all stock
which the employee has a contractual right to purchase will be treated as
stock owned by the employee.
 
  No employee may be granted an Option which permits his rights to purchase
Common Stock under this Plan and all other stock purchase plans of the Company
and its subsidiaries, to accrue at a rate which exceeds $25,000 of the fair
market value of such Common Stock (determined at the time such Option is
granted) for each calendar year in which the Option is outstanding at any
time, as required by Section 423 of the Code.
 
  9. Timing of Purchase. Unless a participating employee has given prior
written notice terminating such employee's participation in the Plan, the
employee has withdrawn all funds from his or her account, or the employee's
participation in the Plan has otherwise been terminated, such employee will be
deemed to have exercised automatically his or her Option to purchase Common
Stock on the last Trading Day of the Offering Period for that number of whole
shares of Common Stock which the accumulated funds in the employee's account
at that time will purchase at the Purchase Price, subject to applicable
adjustments as provided herein. Any balance remaining in an employee's account
at the end of an Offering Period after such purchase of Common Stock will be
automatically carried forward into the employee's account for the next
Offering Period unless the employee has elected not to participate in the next
Offering Period.
 
  10. Issuance of Certificates. As soon as practicable following the end of
each Offering Period, certificates representing shares of Common Stock
purchased under the Plan for such Offering Period shall be issued only in the
name of the employee, in the name of the employee and another person of legal
age as joint tenants with rights of survivorship, or (in the Company's sole
discretion) in the street name of a brokerage firm, bank or other nominee
holder designated by the employee.
 
  11. Rights on Retirement, Death or Termination of Employment. In the event
of a participating employee's termination of employment prior to the last
Trading Day of an Offering Period (whether as a result of the employee's
voluntary or involuntary termination, retirement, death or otherwise), no
payroll deduction will be taken from any pay due and owing to the employee and
the balance in the employee's payroll deduction account will be paid to the
employee or, in the event of the employee's death, (a) to a beneficiary
previously designated in a revocable notice signed by the employee (with any
spousal consent required under state law) or (b) in the absence of such a
designated beneficiary, to the executor or administrator of the employee's
estate or (c) if no such executor or administrator has been appointed to the
knowledge of the Company, to such other person(s) as the Company may, in its
discretion, designate. If, prior to the last Trading Day of an Offering
Period, the Designated Subsidiary by which an employee is employed will cease
to be a subsidiary of the Company, or if the employee is transferred to a
subsidiary of the Company that is not a Designated Subsidiary, the employee
will be deemed to have terminated employment for the purposes of this Plan.
 
  12. Termination of Participation. A participating employee will be refunded
all monies in his or her account, and his or her participation in the Plan
will be terminated if either (a) the Board elects to terminate the Plan, or
(b) the employee ceases to be eligible to participate in the Plan. As soon as
practicable following termination of an employee's participation in the Plan,
the Company will deliver to the employee a check representing the amount
(including interest, if the Committee has determined any interest shall
accrue) in the
 
                                       3
<PAGE>
 
employee's account and a stock certificate representing the number of shares
held in the employee's account. Once terminated, participation may not be
reinstated for the then current Offering Period, but, if otherwise eligible,
the employee may elect to participate in any subsequent Offering Period.
 
  13. Optionees Not Stockholders. Neither the granting of an Option to an
employee nor the deductions from his pay will constitute such employee a
stockholder of the shares of Common Stock covered by an Option under this Plan
until such shares have been purchased by and issued to him.
 
  14. Options Not Transferable. Options under this Plan are not transferable
by a participating employee other than by will or the laws of descent and
distribution, and are exercisable during the employee's lifetime only by the
employee.
 
  15. Withholding of Taxes. To the extent that a participating employee
realizes ordinary income in connection with a sale or other transfer of any
shares of Common Stock purchased under the Plan or the crediting of interest
to the employee's accounts, the Company may withhold amounts needed to cover
such taxes from any payments otherwise due and owing to the participating
employee or from shares that would otherwise be issued to the participating
employee hereunder. Any participating employee who sells or otherwise
transfers shares purchased under the Plan within one year after the shares
were transferred to the participating employee or within two years after the
beginning of the Offering Period in which the shares were purchased must
within 30 days of such sale or transfer notify the Company in writing of the
sale or transfer.
 
  16. Application of Funds. All funds received or held by the Company under
the Plan may be used for any corporate purpose until applied to the purchase
of Common Stock and/or refunded to participating employees and can be
commingled with other general corporate funds. Participating employees'
accounts will not be segregated.
 
  17. Adjustment in Case of Changes Affecting Common Stock. If the number of
outstanding shares of Common Stock is increased or decreased or the shares of
Common Stock are changed into or exchanged for a different number or kind of
shares or other securities of the Company by reason of any recapitalization,
reclassification, stock split, reverse split, combination of shares, exchange
of shares, stock dividend, or other distribution payable in capital stock, or
other increase or decrease in such shares effected without receipt of
consideration by the Company occurring after the effective date of the Plan,
the number and kinds of shares that may be purchased under the Plan shall be
adjusted proportionately and accordingly by the Company. In addition, the
number and kind of shares for which options are outstanding shall be similarly
adjusted so that the proportionate interest, if any, of a participating
employee immediately following such event shall, to the extent practicable, be
the same as immediately prior to such event. Any such adjustment in
outstanding options shall not change the aggregate Purchase Price payable by a
participating employee with respect to shares subject to such options, but
shall include a corresponding proportionate adjustment in the Purchase Price
per share.
 
  18. Mergers and Other Changes of Control.
 
  (a) Definition of Change of Control. For purposes of this Plan, a "Change of
Control" shall mean the occurrence of any of the following:
 
    (i) any "person", as such term is used in Sections 13(d) and 14(d) of the
  Exchange Act (other than the Company, any trustee or other fiduciary
  holding securities under an employee benefit plan of the Company, or any
  corporation owned directly or indirectly by the stockholders of the Company
  in substantially the same proportion as their ownership of stock of the
  Company), is or becomes the "beneficial owner" (as defined in Rule 13d-3
  under the Exchange Act), directly or indirectly, of securities of the
  Company representing 50% or more of the combined voting power of the
  Company's then outstanding securities;
 
                                       4
<PAGE>
 
    (ii) the stockholders of the Company approve a merger or consolidation of
  the Company with any other corporation, other than (A) a merger or
  consolidation which would result in the voting securities of the Company
  outstanding immediately prior thereto continuing to represent (either by
  remaining outstanding or by being converted into voting securities of the
  surviving entity) more than 50% of the combined voting power of the voting
  securities of the Company or such surviving entity outstanding immediately
  after such merger or consolidation or (B) a merger or consolidation
  effected to implement a recapitalization of the Company (or similar
  transaction) in which no "person" (as hereinabove defined) acquires more
  than 50% of the combined voting power of the Company's then outstanding
  securities; or
 
    (iii) the stockholders of the Company approve a plan of complete
  liquidation of the Company or the sale of all or substantially all of the
  Company's assets which, in either case, has not previously been approved by
  a majority of the Disinterested Directors. For purposes of this
  subparagraph (iii), "Disinterested Directors" shall mean individuals who at
  the beginning of any period of two consecutive years ending during the term
  of the Plan (not including any period prior to the adoption of the Plan)
  constitute the Board of Directors of the Corporation, and any new Director
  (other than a Director designated by a person who has entered into an
  agreement with the Corporation to effect any transaction described in
  clause (i), (ii) or (iii) of this Section 18) whose election by the Board
  of Directors or nomination for election by the Corporation's stockholders
  was approved by a vote of at least two-thirds of the Directors then still
  in office who were either Directors at the beginning of the period or whose
  election or whose nomination for election was previously so approved.
 
  (b) Reorganization in Which the Company Is the Surviving
Corporation. Subject to subsection (c) of this Section 18, if the Company
shall be the surviving corporation in any reorganization, merger or
consolidation of the Company with one or more other corporations, all
outstanding options under the Plan shall pertain to and apply to the
securities to which a holder of the number of shares of Common Stock subject
to such options would have been entitled immediately following such
reorganization, merger or consolidation, with a corresponding proportionate
adjustment of the Purchase Price per share so that the aggregate Purchase
Price thereafter shall be the same as the aggregate Purchase Price of the
shares subject to such options immediately prior to such reorganization,
merger or consolidation.
 
  (c) Change of Control. Upon any Change of Control, the Plan and all options
outstanding hereunder shall terminate, except to the extent provision is made
in writing in connection with such transaction for the continuation of the
Plan and/or the assumption of the options theretofore granted, or for the
substitution for such options of new options covering the stock of a successor
corporation, or a parent or subsidiary thereof, with appropriate adjustments
as to the number and kinds of shares and exercise prices, in which event the
Plan and options theretofore granted shall continue in the manner and under
the terms so provided. In the event of any such termination of the Plan, the
Offering Period shall be deemed to have ended on the last Trading Day prior to
such termination, and, unless the Board determines otherwise in its
discretion, each participating employee shall have the ability to choose
either to (i) have all monies then credited to such employee's account
(including interest, to the extent any has accrued) returned to such
participating employee or (ii) exercise his or her options in accordance with
Section 9 on such last Trading Day; provided, however, that if a participating
employee does not exercise his or her right of choice, his or her options
shall be deemed to have been automatically exercised in accordance with
Section 9 on such last Trading Day. The Board shall send written notice of an
event that will result in such a termination to all participating employees
not later than the time at which the Company gives notice thereof to its
stockholders.
 
  (d) No Limitations on the Company. The grant of an Option pursuant to the
Plan shall not affect or limit in any way the right or power of the Company to
make adjustments, reclassifications, reorganizations or changes of its capital
or business structure or to merge, consolidate, dissolve or liquidate, or to
sell or transfer all or any part of its business or assets.
 
                                       5
<PAGE>
 
  19. Amendment of the Plan. The Board may at any time, and from time to time,
amend this Plan in any respect, except that (a) if the approval of any such
amendment by the stockholders of the Company is required by Section 423 of the
Code, such amendment will not be effected without such approval, and (b) in no
event may any amendment be made which would cause the Plan to fail to comply
with Section 423 of the Code unless expressly so provided by the Board.
 
  20. Insufficient Shares. In the event that the total number of shares of
Common Stock specified in elections to be purchased under any Offering plus
the number of shares purchased under previous Offerings under this Plan
exceeds the maximum number of shares issuable under this Plan, the Board or
the Committee will allot the shares then available on a pro rata basis.
 
  21. Termination of the Plan. This Plan may be terminated at any time by the
Board. Upon termination of this Plan all amounts in the payroll deduction
accounts of participating employees will be promptly refunded.
 
  22. Governmental Regulations.
 
  (a) The Company's obligation to sell and deliver Common Stock under this
Plan is subject to listing on a national stock exchange or quotation on Nasdaq
and the approval of all governmental authorities required in connection with
the authorization, issuance or sale of such stock.
 
  (b) The Plan will be governed by the laws of the State of Delaware except to
the extent that such law is preempted by federal law.
 
  (c) The Plan is intended to comply with the provisions of Rule 16b-3(b)(5)
promulgated under the Exchange Act as a "Stock Purchase Plan". Any provision
inconsistent with such Rule will to that extent be inoperative and will not
affect the validity of the Plan.
 
  23.  Effective Date and Approval of Stockholders. The Plan will take effect
on April 1, 1998, subject to approval by the stockholders of the Company as
required by Section 423 of the Code, which approval must occur within twelve
months of the adoption of the Plan by the Board.

to time (the Board, committee or committees hereinafter referred to as the
"Administrator").
 
  (b) Powers of the Administrator. The Administrator shall have all the powers
vested in it by the terms of the Plan, such powers to include authority, in
its sole and absolute discretion, to grant Awards under the Plan, prescribe
Grant Agreements evidencing such Awards and establish programs for granting
Awards.
 
                                       2
<PAGE>
 
  The Administrator shall have full power and authority to take all other
actions necessary to carry out the purpose and intent of the Plan, including,
but not limited to, the authority to: (i) determine the eligible persons to
whom, and the time or times at which Awards shall be granted; (ii) determine
the types of Awards to be granted; (iii) determine the number of shares to be
covered by or used for reference purposes for each Award; (iv) impose such
terms, limitations, restrictions and conditions upon any such Award as the

outstanding Awards, or accept the surrender of outstanding Awards and
substitute new Awards (provided however, that, except as provided in Section
7(d) of the Plan, any modification that would materially adversely affect any
outstanding Award shall not be made without the consent of the holder); (vi)
accelerate or otherwise change the time in which an Award may be exercised or
becomes payable and to waive or accelerate the lapse, in whole or in part, of
any restriction or condition with respect to such Award, including, but not
limited to, any restriction or condition with respect to the vesting or
exercisability of an Award following termination of any grantee's employment;
and (vii) establish objectives and conditions, if any, for earning Awards and
determining whether Awards will be paid after the end of a performance period.
 
  The Administrator shall have full power and authority, in its sole and
absolute discretion, to administer and interpret the Plan and to adopt and
interpret such rules, regulations, agreements, guidelines and instruments for
the administration of the Plan and for the conduct of its business as the
Administrator deems necessary or advisable.
 
  (c) Non-Uniform Determinations. The Administrator's determinations under the
Plan (including without limitation, determinations of the persons to receive
Awards, the form, amount and timing of such Awards, the terms and provisions
of such Awards and the Grant Agreements evidencing such Awards) need not be
uniform and may be made by the Administrator selectively among persons who
receive, or are eligible to receive, Awards under the Plan, whether or not
such persons are similarly situated.
 
  (d) Limited Liability. To the maximum extent permitted by law, no member of
the Administrator shall be liable for any action taken or decision made in
good faith relating to the Plan or any Award thereunder.

  4. SHARES AVAILABLE FOR THE PLAN; MAXIMUM AWARDS
 
  Subject to adjustments as provided in Section 7(d) of the Plan, the shares
of Common Stock that may be issued with respect to Awards granted under the
Plan shall not exceed an aggregate of 1,800,000 shares of Common Stock. The
Corporation shall reserve such number of shares for Awards under the Plan,
subject to adjustments as provided in Section 7(d) of the Plan. If any Award,
or portion of an Award, under the Plan expires or terminates unexercised,
becomes unexercisable or is forfeited or otherwise terminated, surrendered or
canceled as to any shares, or if any shares of Common Stock are surrendered to
the Corporation in connection with any Award (whether or not such surrendered
shares were acquired pursuant to any Award), the shares subject to such Award
and the surrendered shares shall thereafter be available for further Awards
under the Plan; provided, however, that any such shares that are surrendered
to the Corporation in connection with any Award or that are otherwise
forfeited after issuance shall not be available for purchase pursuant to
incentive stock options intended to qualify under Code section 422.
 
                                       3
<PAGE>
 
  Subject to adjustments as provided in Section 7(d) of the Plan, the maximum
number of shares of Common Stock subject to Awards of any combination that may
be granted during any one fiscal year of the Corporation to any one individual
shall be limited to 500,000. Such per-individual limit shall not be adjusted
to effect a restoration of shares of Common Stock with respect to which the
related Award is terminated, surrendered or canceled.
 
  5. PARTICIPATION
 
  Participation in the Plan shall be open to all employees, officers,
directors and consultants of the Corporation, or of any Affiliate of the
Corporation, as may be selected by the Administrator from time to time.
 
  6. AWARDS
 
  The Administrator, in its sole discretion, establishes the terms of all
Awards granted under the Plan. Awards may be granted individually or in tandem
with other types of Awards. All Awards are subject to the terms and conditions
provided in the Grant Agreement.
 
  (a) Stock Options. The Administrator may from time to time grant to eligible
participants Awards of incentive stock options as that term is defined in Code
section 422 or nonqualified stock options; provided, however, that Awards of
incentive stock options shall be limited to employees of the Corporation or of
any Parent or Subsidiary of the Corporation. Options intended to qualify as
incentive stock options under Code section 422 must have an exercise price at
least equal to Fair Market Value on the date of grant, but nonqualified stock
options may be granted with an exercise price less than Fair Market Value. No
stock option shall be an incentive stock option unless so designated by the
Administrator at the time of grant or in the Grant Agreement evidencing such
stock option.
 
  (b) Stock Appreciation Rights. The Administrator may from time to time grant
to eligible participants Awards of Stock Appreciation Rights ("SAR"). An SAR
entitles the grantee to receive, subject to the provisions of the Plan and the
Grant Agreement, a payment having an aggregate value equal to the product of
(i) the excess of (A) the Fair Market Value on the exercise date of one share
of Common Stock over (B) the base price per share specified in the Grant
Agreement, times (ii) the number of shares specified by the SAR, or portion
thereof, which is exercised. Payment by the Corporation of the amount
receivable upon any exercise of an SAR may be made by the delivery of Common
Stock or cash, or any combination of Common Stock and cash, as determined in
the sole discretion of the Administrator. If upon settlement of the exercise
of an SAR a grantee is to receive a portion of such payment in shares of
Common Stock, the number of shares shall be determined by dividing such
portion by the Fair Market Value of a share of Common Stock on the exercise
date. No fractional shares shall be used for such payment and the
Administrator shall determine whether cash shall be given in lieu of such
fractional shares or whether such fractional shares shall be eliminated.
 
  (c) Stock Awards. The Administrator may from time to time grant restricted
or unrestricted stock Awards to eligible participants in such amounts, on such
terms and conditions, and for such consideration, including no consideration
or such minimum consideration as may be required by law, as it shall
determine. A stock Award may be paid in Common Stock, in cash, or in a
combination of Common Stock and cash, as determined in the sole discretion of
the Administrator.
 
  (d) Phantom Stock. The Administrator may from time to time grant Awards to
eligible participants denominated in stock-equivalent units ("phantom stock")
in such amounts and on such terms and conditions as it shall determine.
Phantom stock units granted to a participant shall be credited to a
bookkeeping reserve account solely for accounting purposes and shall not
require a segregation of any of the Corporation's assets. An Award of phantom
stock may be settled in Common Stock, in cash, or in a combination of Common
Stock and cash, as determined in the sole discretion of the Administrator.
Except as otherwise provided in the applicable Grant Agreement, the grantee
shall not have the rights of a stockholder with respect to any shares of
Common Stock represented by a phantom stock unit solely as a result of the
grant of a phantom stock unit to the grantee.

  (e) Performance Awards. The Administrator may, in its discretion, grant
performance awards which become payable on account of attainment of one or
more performance goals established by the Administrator. Performance awards
may be paid by the delivery of Common Stock or cash, or any combination of
Common Stock and cash, as determined in the sole discretion of the
Administrator. Performance goals established by the Administrator may be based
on the Corporation's or an Affiliate's operating income or one or more other
business criteria selected by the Administrator that apply to an individual or
group of individuals, a business unit, or the Corporation or an Affiliate as a
whole, over such performance period as the Administrator may designate.
 
  7. MISCELLANEOUS
 
  (a) Withholding of Taxes. Grantees and holders of Awards shall pay to the
Corporation, or make provision satisfactory to the Administrator for payment
of, any taxes required to be withheld in respect of Awards under the Plan no
later than the date of the event creating the tax liability. The Corporation
may, to the extent permitted by law, deduct any such tax obligations from any
payment of any kind otherwise due to the grantee or holder of an Award. In the
event that payment to the Corporation of such tax obligations is made in
shares of Common Stock, such shares shall be valued at Fair Market Value on
the applicable date for such purposes.
 
  (b) Loans. The Corporation may make or guarantee loans to grantees to assist
grantees in exercising Awards and satisfying any withholding tax obligations.
 
  (c) Transferability. Except as otherwise determined by the Administrator,
and in any event in the case of an incentive stock option or a stock
appreciation right granted with respect to an incentive stock option, no Award
granted under the Plan shall be transferable by a grantee otherwise than by
will or the laws of descent and distribution or pursuant to a domestic
relations order within the meaning of Section 414(p) of the Code. Unless
otherwise determined by the Administrator in accord with the provisions of the
immediately preceding sentence, an Award may be exercised during the lifetime
of the grantee or an alternate payee (as applicable), only by the grantee or
the grantee's alternate payee under a domestic relations order as described
above, as the case may be, or, during the period the grantee or alternate
payee is under a legal disability, by such individual's guardian or legal
representative.
 
  (d) Adjustments; Business Combinations. In the event of changes in the
Common Stock of the Corporation by reason of any stock dividend, split-up,
recapitalization, merger, consolidation, business combination or exchange of
shares and the like, the Administrator shall, in its discretion, make
appropriate adjustments to the maximum number and kind of shares reserved for
issuance or with respect to which Awards may be granted under the Plan as
provided in Section 4 of the Plan and to the number, kind and price of shares
covered by Awards granted, and shall, in its discretion and without the
consent of holders of Awards, make any other adjustments in Awards, including
but not limited to reducing the number of shares subject to Awards or
providing or mandating alternative settlement methods such as settlement of
the Awards in cash or in shares of Common Stock or other securities of the
Corporation or of any other entity, or in any other matters which relate to
Awards as the Administrator shall, in its sole discretion, determine to be
necessary or appropriate.
 
  Subject to any provisions in any Grant Agreement providing a result more
favorable to the holder of such Award, in the event of a "Change in Control,"
any restrictions on vesting or exercising any outstanding Award issued
pursuant to the Plan prior to any given date shall terminate with respect to
the number of whole shares constituting 50% of the shares subject to any such
restriction.
 
  Notwithstanding anything in the Plan to the contrary and without the consent
of holders of Awards, the Administrator, in its sole discretion, may make any
modifications to any Awards, including but not limited to cancellation,
forfeiture, surrender or other termination of the Awards in whole or in part
regardless of the vested status of the Award, in order to facilitate any
business combination that is authorized by the Board to comply with
requirements for treatment as a pooling of interests transaction for
accounting purposes under generally accepted accounting principles.
 
                                       5
<PAGE>
 
  The Administrator is authorized to make, in its discretion and without the
consent of holders of Awards, adjustments in the terms and conditions of, and
the criteria included in, Awards in recognition of unusual or nonrecurring
events affecting the Corporation, or the financial statements of the
Corporation or any Subsidiary, or of changes in applicable laws, regulations,
or accounting principles, whenever the Administrator determines that such
adjustments are appropriate in order to prevent dilution or enlargement of the
benefits or potential benefits intended to be made available under the Plan.
 
  (e) Substitution of Awards in Mergers and Acquisitions. Awards may be
granted under the Plan from time to time in substitution for Awards held by
employees or directors of entities who become or are about to become employees
or directors of the Corporation or an Affiliate as the result of a merger or
consolidation of the employing entity with the Corporation or an Affiliate, or
the acquisition by the Corporation or an Affiliate of the assets or stock of
the employing entity. The terms and conditions of any substitute Awards so
granted may vary from the terms and conditions set forth herein to the extent
that the Administrator deems appropriate at the time of grant to conform the
substitute Awards to the provisions of the awards for which they are
substituted.
 
  (f) Termination, Amendment and Modification of the Plan. The Board may
terminate, amend or modify the Plan or any portion thereof at any time.
 
  (g) Non-Guarantee of Employment or Service. Nothing in the Plan or in any
Grant Agreement thereunder shall confer any right on an individual to continue
in the service of the Corporation or shall interfere in any way with the right
of the Corporation to terminate such service at any time.
 
  (h) No Trust or Fund Created. Neither the Plan nor any Award shall create or
be construed to create a trust or separate fund of any kind or a fiduciary
relationship between the Corporation and a grantee or any other person. To the
extent that any grantee or other person acquires a right to receive payments
from the Corporation pursuant to an Award, such right shall be no greater than
the right of any unsecured general creditor of the Corporation.
 
  (i) Governing Law. The validity, construction and effect of the Plan, of
Grant Agreements entered into pursuant to the Plan, and of any rules,
regulations, determinations or decisions made by the Administrator relating to
the Plan or such Grant Agreements, and the rights of any and all persons
having or claiming to have any interest therein or thereunder, shall be
determined exclusively in accordance with applicable federal laws and the laws
of the State of Delaware, without regard to its conflict of laws principles.
 
  (j) Effective Date; Termination Date. The Plan is effective as of the date
on which the Plan was adopted by the Board, subject to approval of the
stockholders within twelve months before or after such date. No Award shall be
granted under the Plan after the close of business on the day immediately
preceding the tenth anniversary of the effective date of the Plan. Subject to
other applicable provisions of the Plan, all Awards made under the Plan prior
to such termination of the Plan shall remain in effect until such Awards have
been satisfied or terminated in accordance with the Plan and the terms of such
Awards.

                           AXENT TECHNOLOGIES, INC.
                             EXCHANGE OPTION PLAN
                               FOR OPTIONEES OF
                             RAPTOR SYSTEMS, INC.
 
  1. PURPOSE
 
  This Exchange Option Plan For Optionees of Raptor Systems, Inc. (the "Plan")
is an amendment and restatement of the Raptor Systems, Inc. 1995 Stock Option
And Grant Plan as hereby assumed and adopted by AXENT Technologies, Inc. (the
"Company") for the sole purpose of granting stock options for the purchase of
shares of common stock of the Company, par value $0.02 per share ("Replacement
Options"), in exchange for stock options for the purchase of shares of common
stock of Raptor Systems, Inc., par value $0.01 per share ("Raptor Options"),
with respect to any such Raptor Options that are outstanding immediately prior
to the effective time (the "Effective Time") of the merger pursuant to the
Agreement and Plan of Merger to which the Company and Raptor Systems, Inc. are
parties, dated December 1, 1997 (the "Merger Agreement") as defined therein.
Notwithstanding anything to the contrary contained in the Plan immediately
prior to the Effective Time, the Plan shall continue in effect in accordance
with the provisions set forth below.
 
  The Plan is intended as a performance incentive for officers, employees,
directors, consultants and other key persons of the Company who performed
services for Raptor Systems, Inc. or its subsidiaries prior to the Effective
Time to enable the persons to whom options are granted (the "Optionees") to
acquire or increase a proprietary interest in the success of the Company. The
Company intends that this purpose will be effected by the granting of
Replacement Options in the form of "incentive stock options" ("Incentive
Options") as defined in Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code"), and nonqualified stock options ("Nonqualified Options").
 
  2. OPTIONS TO BE GRANTED AND ADMINISTRATION
 
  (a) No options shall be granted under this Plan except such Replacement
Options as are required to be granted pursuant to the terms and conditions of
the Merger Agreement. Replacement Options granted under the Plan may be either
Incentive Options or Nonqualified Options, and shall be designated as such at
the time of grant. To the extent that any option intended to be an Incentive
Option shall fail to qualify as an "incentive stock option" under the Code,
such option shall be deemed to be a Nonqualified Option.
 
  (b) The Plan shall be administered by either the Board of Directors of the
Company or a committee (the "Committee"), appointed by the Board of Directors
and comprised of not fewer than two directors of the Company, each of whom
shall be a "non-employee director" of the Company within the meaning of Rule
16b-3(b)(3) promulgated under the Securities Exchange Act of 1934, as amended,
and each of whom shall also be an "outside director" within the meaning of
Rule 162(m) of the Code and regulations promulgated thereunder. All references
to the "Committee" herein may also be deemed to refer to the Board of
Directors; provided, however, that the Board of Directors of the Company or
the Compensation Committee thereof, in its discretion, may delegate to the
Chief Executive Officer of the Company all or part of the Compensation
Committee's authority and duties with respect to the granting of Incentive
Options to individuals who are not subject to the reporting and other
provisions of Section 16 of the Act or "covered employees" within the meaning
of Section 162(m) of the Code. The Board of Directors or the Compensation
Committee may revoke or amend the terms of a delegation at any time but such
action shall not invalidate any prior actions of the Board of Directors' or
Compensation Committee's delegate or delegates that were consistent with the
terms of the Plan.
 
  (c) Subject to the terms and conditions of the Plan and the Merger
Agreement, the Committee shall have the power:
 
    (i) to determine the Replacement Options to be granted to eligible
  persons under the Plan, to prescribe the terms and provisions (which need
  not be identical) of Replacement Options granted under the Plan to such
  persons and to approve the grant of Replacement Options;
<PAGE>
 
    (ii) to construe and interpret the Plan and grants thereunder and to
  establish, amend, and revoke rules and regulations for administration of
  the Plan. In this connection, the Committee may correct any defect or
  supply any omission, or reconcile any inconsistency in the Plan, in any
  option agreement, or in any related agreements, in the manner and to the
  extent it shall deem necessary or expedient to make the Plan fully
  effective;
 
    (iii) to accelerate the exercisability or vesting of all or any portion
  of any Replacement Option;
 
    (iv) subject to the provisions of Section 5(a), to extend the period in
  which Replacement Options may be exercised; and
 
    (v) generally, to exercise such powers and to perform such acts as are
  deemed necessary or expedient to promote the best interests of the Company
  with respect to the Plan.
 
  All decisions and determinations by the Committee in the exercise of its
powers shall be final and binding upon the Company and the Optionees.
 
  3. STOCK
 
  The stock subject to the options granted under the Plan shall be shares of
the Company's authorized but unissued common stock, par value $.02 per share
(the "Common Stock"). The total number of shares that may be issued under the
Plan shall not exceed an aggregate of one million eight hundred seventy-eight
thousand seven hundred twenty-six (1,878,726) shares of Common Stock. Options
with respect to no more than 250,000 shares of Common Stock (specified with
respect to shares issuable pursuant to Raptor Options granted prior the
Effective Time without giving effect to the exchange ratio (the "Exchange
Ratio") under the Merger Agreement, as defined therein) may be granted to any
one individual during any one calendar year period, but such limit is not
applicable to the extent that such options are Replacement Options granted
hereunder in exchange for Raptor Options that were outstanding in whole or in
part immediately prior to the Effective Time. Such numbers shall be subject to
adjustment as provided in Section 7 hereof.
 
  4. ELIGIBILITY
 
  (a) Replacement Options that are intended to be Incentive Options may be
granted only to officers or other employees of the Company or its
Subsidiaries, including members of the Board of Directors who are also
employees of the Company or its Subsidiaries and to such other former
employees of Raptor Systems, Inc. or its Subsidiaries as may be permitted
under Section 424(a) of the Code in exchange for outstanding options held by
such persons immediately preceding the Effective Time. The term "Subsidiaries"
includes any corporations in which stock possessing fifty percent or more of
the total combined voting power of all classes of stock is owned directly or
indirectly by the Company. Replacement Options that are intended to be
Nonqualified Options may be granted to officers or other employees of the
Company or its Subsidiaries, members of the Board of Directors and consultants
and other key persons who provide services to the Company or its Subsidiaries
or provided services to Raptor Systems, Inc. or its subsidiaries (regardless
of whether they are also employees) in exchange for outstanding options held
by such persons immediately preceding the Effective Time.
 
  (b) Except as may be permitted under Section 424(a) of the Code, no person
shall be eligible to receive any Incentive Option under the Plan if, at the
date of grant, such person beneficially owns stock representing in excess of
10% of the total combined voting power of all classes of stock of the Company
or of its parent or Subsidiary (a "Ten Percent Stockholder") unless
notwithstanding anything in this Plan to the contrary (i) the purchase price
for the Common Stock subject to such option is at least 110% of the fair
market value of such stock at the time of the grant and (ii) the option by its
terms is not exercisable more than five years from the date of grant thereof.
 
  (c) Notwithstanding any other provision of the Plan, to the extent that the
aggregate fair market value of the stock with respect to which Incentive
Options are exercisable for the first time by any individual during any
calendar year (under all plans of the Company and its parent and Subsidiaries)
exceeds $100,000, the options
 
                                       2
<PAGE>
 
attributable to the excess over $100,000 shall be treated as Nonqualified
Options under the Plan. Such annual limitation shall be applied to Replacement
Options by taking Incentive Options into account in the order in which the
Raptor Options for which they were exchanged were granted.
 
  5. TERMS OF THE OPTION AGREEMENTS
 
  Subject to the terms and conditions of the Plan and the Merger Agreement,
each option agreement for a Replacement Option shall contain substantially the
same terms and conditions of the option agreement for the Raptor Option that
is being replaced thereby, giving effect to any acceleration of vesting for
such Raptor Option as a result of the consummation of the merger to the extent
required by the Merger Agreement, and shall not give the Optionee any
additional benefits that the Optionee did not have under the Raptor Option
other than the continuation of the term and exercisability thereof after the
Effective Time in accordance with the original terms of such Raptor Option.
Option agreements need not be identical, but each option agreement by
appropriate language shall include the substance of all of the following
provisions:
 
    (a) Expiration; Termination of Employment. Notwithstanding any other
  provision of the Plan or of any option agreement, each Replacement Option
  shall expire on the date specified in the option agreement, which date in
  the case of any Incentive Option shall not be later than the tenth
  anniversary of the date on which the Raptor Option that is replaced by such
  Replacement Option was granted; provided, however, that if such Incentive
  Option is held by a Ten Percent Stockholder (within the meaning of Section
  422 of the Code as applied to Raptor Systems, Inc. at the time of the grant
  of the Raptor Option), the expiration date of such Incentive Option shall
  not be later than five years from the date of grant of the Raptor Option.
  If an Optionee's employment or service as a director with the Company and
  its Subsidiaries terminates for any reason, the Committee may in its
  discretion provide, at any time, that any outstanding option granted to
  such Optionee under the Plan shall be exercisable for such period following
  termination of employment as may be specified by the Committee, which
  period shall not exceed three months for purposes of Incentive Options
  where such termination is not due to death or disability, subject to the
  expiration date of such option. In case of termination on account of
  disability (within the meaning of Section 22(e)(3) of the Code), Incentive
  Options may be exercisable for a period of up to one year following
  termination of employment, subject to the expiration date of such option.
 
    (b) Minimum Shares Exercisable. The minimum number of shares with respect
  to which an option may be exercised at any one time shall be one hundred
  (100) shares, or such lesser number as is subject to exercise under the
  option at the time, provided that no fractional shares may be issued.
 
    (c) Exercise. Each option shall be exercisable in such installments
  (which need not be equal) and at such times as may be designated by the
  Committee. To the extent not exercised, installments shall accumulate and
  be exercisable, in whole or in part, at any time after becoming
  exercisable, but not later than the date the option expires.
 
    (d) Purchase Price. The purchase price per share of Common Stock subject
  to each Replacement Option shall be the per share purchase price of the
  Raptor Option in exchange for which the Replacement Option is granted
  divided by the Exchange Ratio, rounded up to the nearest cent, as
  determined in accordance with the Merger Agreement and, if the Replacement
  Option is an Incentive Option, in accordance with Section 424(a) of the
  Code.
 
    (e) Fair Market Value of Shares. For the purposes of the Plan, the fair
  market value of the Common Stock shall be determined in good faith by the
  Committee; provided, however, that (i) if the Common Stock is admitted to
  quotation on the National Association of Securities Dealers Automated
  Quotation System ("Nasdaq") Small-Cap Market on the date the option is
  granted, the fair market value shall not be less than the average of the
  highest bid and lowest asked prices of the Common Stock on Nasdaq reported
  for such date or, if no prices were reported for such date, for the last
  date preceding such date on which prices were reported and (ii) if the
  Common Stock is admitted to trading on a national securities exchange or
  the Nasdaq National Market System on the date the option is granted, the
  fair market value shall not be less than the closing price reported for the
  Common Stock on such exchange or system for such date or, if no sales were
  reported for such date, for the last date preceding such date for which a
  sale was reported.
 
                                       3
<PAGE>
 
    (f) Rights of Optionees. No Optionee shall be deemed for any purpose to
  be the owner of any shares of Common Stock subject to any option unless and
  until (i) the option shall have been exercised pursuant to the terms
  thereof, (ii) all requirements under applicable law and regulations shall
  have been complied with to the satisfaction of the Company, (iii) the
  Company shall have issued and delivered the shares to the Optionee, and
  (iv) the Optionee's name shall have been entered as a stockholder of record
  on the books of the Company. Thereupon, the Optionee shall have full
  voting, dividend and other ownership rights with respect to such shares of
  Common Stock.
 
    (g) Transfer. No option granted hereunder shall be transferable by the
  Optionee other than by will or by the laws of descent and distribution, and
  such option may be exercised during the Optionee's lifetime only by the
  Optionee, or his or her guardian or legal representative. Notwithstanding
  the foregoing, the Committee may provide in an option agreement that the
  Optionee may transfer, without consideration for the transfer, his
  Nonqualified Options to members of his immediate family, to trusts for the
  benefit of such family members and to partnerships in which such family
  members are the only partners.
 
  6. METHOD OF EXERCISE; PAYMENT OF PURCHASE PRICE
 
  (a) Any option granted under the Plan may be exercised by the Optionee in
whole or, subject to Section 5(b) hereof, in part by delivering to the Company
on any business day a written notice specifying the number of shares of Common
Stock the Optionee then desires to purchase (the "Notice"). As a condition
precedent to the exercise of any option, the Optionee shall pay or make
arrangements for the payment of all taxes to be withheld, in accordance with
Section 9 of the Plan.
 
  (b) Payment for the shares of Common Stock purchased pursuant to the
exercise of an option shall be made either: (i) in cash, or by certified or
bank check or other payment acceptable to the Company, equal to the option
exercise price for the number of shares specified in the Notice (the "Total
Option Price"); (ii) if authorized by the applicable option agreement and if
permitted by law and the Committee, by delivery of shares of Common Stock that
the Optionee has beneficially owned for more than six months and which the
Optionee may freely transfer having a fair market value, determined by
reference to the provisions of Section 5(e) hereof, equal to or less than the
Total Option Price, plus cash in an amount equal to the excess, if any, of the
Total Option Price over the fair market value of such shares of Common Stock;
or (iii) by the Optionee delivering the Notice to the Company together with
irrevocable instructions to a broker to promptly deliver the Total Option
Price to the Company in cash or by other method of payment acceptable to the
Company; provided, however, that the Optionee and the broker shall comply with
such procedures and enter into such agreements of indemnity or other
agreements as the Company shall prescribe as a condition of payment under this
clause (iii).
 
  (c) The delivery of certificates representing shares of Common Stock to be
purchased pursuant to the exercise of an option will be contingent upon the
Company's receipt of the Total Option Price and of any written representations
from the Optionee required by the Committee, and the fulfillment of any other
requirements contained in the option agreement or applicable provisions of
law.
 
  7. ADJUSTMENT UPON CHANGES IN CAPITALIZATION
 
  (a) If the shares of the Company's Common Stock as a whole are increased,
decreased, changed into or exchanged for a different number or kind of shares
or securities of the Company, whether through merger, consolidation,
reorganization, recapitalization, reclassification, stock dividend, stock
split, combination of shares, exchange of shares, change in corporate
structure or the like, an appropriate and proportionate adjustment shall be
made in the number and kind of shares subject to the Plan and subject to the
"per individual" grant limit specified in Section 3, and in the number, kind,
and per share exercise price of shares subject to unexercised options or
portions thereof granted prior to any such change. In the event of any such
adjustment in an outstanding option, the Optionee thereafter shall have the
right to purchase the number of shares under such option at the per share
price, as so adjusted, which the Optionee could purchase at the total purchase
price applicable to the option immediately prior to such adjustment.
 
 
                                       4
<PAGE>
 
  (b) Adjustments under this Section 7 shall be determined by the Committee
and such determinations shall be conclusive. The Committee shall have the
discretion and power in any such event to determine and to make effective
provision for acceleration of the time or times at which any option or portion
thereof shall become exercisable. No fractional shares of Common Stock shall
be issued under the Plan on account of any adjustment specified above.
 
  8. EFFECT OF CERTAIN TRANSACTIONS
 
  In the case of (i) the dissolution or liquidation of the Company, (ii) a
reorganization, merger, consolidation or other business combination in which
the Company is acquired by another entity (other than a holding company formed
by the Company) or in which the Company is not the surviving entity, or (iii)
the sale of all or substantially all of the assets of the Company to another
entity, the Plan and the options issued hereunder shall terminate upon the
effectiveness of any such transaction or event unless provision is made in
connection with such transaction for the assumption of the options issued
hereunder then outstanding, or the substitution for such options of new
options of the successor entity or parent thereof, with appropriate adjustment
as to the number and kind of shares and the per share exercise prices as
provided in Section 7. In the event of such termination, (A) all outstanding
vested options and (B) between fifty percent (50%) and one hundred percent
(100%) of the outstanding options that are not vested, such percentage to be
determined by the Committee at the time of the grant of options to each
Optionee, shall be exercisable for at least fifteen (15) days prior to the
date of such termination whether or not otherwise exercisable during such
period.
 
  9. TAX WITHHOLDING
 
  (a) Each Optionee shall, no later than the exercise date of any option, pay
to the Company, or make arrangements satisfactory to the Committee regarding
payment of any Federal, state, or local taxes of any kind required by law to
be withheld with respect to such income. The Company and its Subsidiaries
shall, to the extent permitted by law, have the right to deduct any such taxes
from any payment of any kind otherwise due to the Optionee.
 
  (b) An Optionee may elect to have his tax withholding obligation satisfied,
in whole or in part, by (i) authorizing the Company to withhold from shares of
Common Stock to be issued pursuant to any option the number of shares with an
aggregate fair market value (determined by reference to the provisions of
Section 5(e) hereof), that would satisfy the withholding amount due, or (ii)
transferring to the Company shares of Common Stock owned by the Optionee with
an aggregate fair market value (determined by reference to the provisions of
Section 5(e) hereof) that would satisfy the withholding amount due.
 
  10. CONDITION TO GRANTS OF COMMON STOCK
 
  In addition to terms and conditions expressly contemplated by the Plan, the
Committee may also impose such other terms and conditions on the grant of any
Common Stock under the Plan as it may determine.
 
  11. AMENDMENT OF THE PLAN
 
  The Board of Directors may discontinue the Plan or amend the Plan at any
time. Plan amendments shall be subject to approval by the Company stockholders
if and to the extent determined by the Committee to be necessary to ensure
that Incentive Options granted under the Plan are qualified under Section 422
of the Code. Except as provided in Sections 7 and 8 hereof, rights and
obligations under any option granted before any amendment of the Plan shall
not be altered or impaired by such amendment, except with the consent of the
Optionee.
 
   12. NONEXCLUSIVITY OF THE PLAN
 
  Neither the adoption of the Plan by the Board of Directors nor the
submission of the Plan to the stockholders of the Company for approval shall
be construed as creating any limitations on the power of the Board of
 
                                       5
<PAGE>
 
Directors to adopt such other incentive arrangements as it may deem desirable,
including, without limitation, the granting of stock or stock options
otherwise than under the Plan, and such arrangements may be either applicable
generally or only in specific cases. Neither the Plan nor any option granted
hereunder shall be deemed to confer upon any employee any right to continued
employment with the Company or its Subsidiaries.
 
  13. GOVERNMENT AND OTHER REGULATIONS; GOVERNING LAW
 
  (a) The obligation of the Company to sell and deliver shares of Common Stock
with respect to options granted under the Plan shall be subject to all
applicable laws, rules and regulations, including all applicable federal and
state securities laws, and the obtaining of all such approvals by governmental
agencies as may be deemed necessary or appropriate by the Committee.
 
  (b) The Plan shall be governed by Delaware law, except to the extent that
such law is preempted by federal law.
 
  14. EFFECTIVE DATE OF PLAN
 
  The Plan shall become effective upon the Effective Time. No options may be
granted under the Plan after the tenth anniversary of the effective date of
the Stock Option Plan initially adopted by Raptor Systems, Inc.

20. INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
  Section 145 of the Delaware General Corporation Law ("Section 145") permits
indemnification of directors, officers, agents and controlling persons of a
corporation under certain conditions and subject to certain limitations. The
Registrant's Bylaws include provisions to require the Registrant to indemnify
its directors and officers to the fullest extent permitted by Section 145,
including circumstances in which indemnification is otherwise discretionary.
Section 145 also empowers the Registrant to purchase and maintain insurance
that protects its officers, directors, employees and agents against any
liabilities incurred in connection with their service in such positions.
 
  At present, there is no pending litigation or proceeding involving a
director or officer of the Registrant as to which indemnification is being
sought nor is the Registrant aware of any threatened litigation that may
result in claims for indemnification by any officer or director.

22. UNDERTAKINGS
 
  A. The Registrant hereby undertakes as follows:
 
    1. That prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this Registration
  Statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c), the Registrant undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by persons who may be deemed
  underwriters, in addition to the information called for by the other items
  of the applicable form.
 
    2. That every prospectus (i) that is filed pursuant to paragraph (1)
  immediately preceding, or (ii) that purports to meet the requirements of
  Section 10(a)(3) of the Securities Act and is used in connection with an
  offering of securities subject to Rule 415, will be filed as a part of an
  amendment to this Registration Statement and will not be used until such
  amendment is effective, and that, for purposes of determining any liability
  under the Securities Act, each such post-effective amendment shall be
  deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.
 
  B. The Registrant hereby undertakes to respond to requests for information
that is incorporated by reference into the prospectus pursuant to Items 4,
10(b), 11, or 13 of this Form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of this Registration Statement through the
date of responding to the request.
 
  C. The Registrant hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in this
Registration Statement when it became effective.
 
  D. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.

AXENT Technologies, Inc.

Rockville, Maryland  20850

Gentlemen:

     We have assisted in the preparation and filing with the Securities and
Exchange Commission of a Registration Statement on Form S-4 (the "Registration
Statement"), relating to 10,865,404 shares (the "Shares") of Common Stock, $0.02
par value per share, of AXENT Technologies, Inc., a Delaware corporation (the
"Company"), to be issued in connection with the merger of Raptor Systems, Inc.
("Raptor") with a wholly-owned subsidiary of the Company ("Sub").

     We have examined the Certificate of Incorporation and By-laws of the
Company, and all amendments thereto, and have examined and relied upon the
originals, or copies certified to our satisfaction, of such records of meetings
of the directors and stockholders of the Company, documents and other
instruments as in our judgment are necessary or appropriate to enable us to
render the opinions expressed below.

     In examining the foregoing documents, we have assumed the genuineness of
all signatures and the authenticity of all documents submitted to us as
originals, the conformity to original documents of all documents submitted to us
as certified or photostatic copies, and the authenticity of the originals of
such latter documents.

     Based on the foregoing, we are of the opinion that the Shares have been
duly authorized and, when issued upon consummation of the Merger in accordance
with the terms and provisions of the Agreement and Plan of Merger, by and among
the Company, Raptor and Sub, dated as of December 1, 1997, will be duly and
validly issued, fully paid and nonassessable.

     We hereby consent to the use of our name in the Registration Statement and
under the caption "Legal Matters" in the related Prospectus/Proxy Statement and
consent to the filing of this opinion as an exhibit to the Registration
Statement.

                                               Very truly yours,

     Re:  Agreement and Plan of Merger dated December 1, 1997, Among Axent
          Technologies, Inc., Axquisition Two, Inc. and Raptor Systems, Inc.
          -------------------------------------------------------------------
          
Ladies and Gentlemen:

     We have acted as counsel for AXENT Technologies, Inc., a Delaware
corporation (the "Parent"), in connection with the proposed merger (the
"Merger") of Axquisition Two, Inc. ("Sub"), a Delaware corporation and a wholly-
owned subsidiary of Parent, with and into Raptor Systems, Inc. (the "Company")
pursuant to an Agreement and Plan of Merger dated December 1, 1997 (the "Merger
Agreement"), among Parent, Sub and the Company, under which each issued and
outstanding share of common stock of the Company (other than shares owned
directly by Parent or the Company) will be exchanged for common stock of Parent.

     In that connection you have requested our opinion regarding the material
Federal income tax consequences of the Merger.  In providing our opinion, we
have examined the Merger Agreement, the Prospectus/Joint Proxy Statement of
Parent and the Company dated January 5, 1998 (the "Prospectus/Proxy Statement"),
and such other documents and corporate records as we have deemed necessary or
appropriate for purposes of our opinion.  In addition, we have assumed that (i)
the Merger will be consummated in accordance with the provisions of the Merger
Agreement and in the manner contemplated by the Prospectus/Proxy Statement, (ii)
the representations made to us by Parent and the Company in their respective
letters to us dated January __, 1998 (the "Representation Letters"), and
delivered to us for purposes of this opinion are accurate and complete, (iii)
the representations set forth in the Representation Letters that are provided to
the "best knowledge" of Parent or the Company, as the case may be, are accurate
and correct as if made without such qualification, (iv) the representations made
to us by certain shareholders of the Company in the Continuity of Interest
Letter dated January __, 1998, and delivered to us for purposes of this opinion
are accurate and complete and (v) the opinion of Goodwin, Procter & Hoar LLP,
substantially identical in form to this opinion has been delivered and not
withdrawn.

     Based upon the foregoing, in our opinion, for Federal income tax purposes:

                                                                 Piper & Marbury
                                                                       L.L.P.

          (i)   the Merger will constitute either (A) a reorganization within
     the meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Internal
     Revenue Code of 1986, as amended (the "Code"), or (B) if the Company is
     liquidated or merged upstream into Parent after the Merger and if such
     liquidation or merger is determined to be pursuant to the overall plan of
     reorganization contemplated by the Merger Agreement, a reorganization
     within the meaning of Section 368(a)(1)(A) or Section 368(a)(1)(C) of the
     Code depending upon whether the Company is merged upstream or liquidated
     after the Merger, and, in the case of either (A) or (B), Parent, Sub and
     the Company will each be a party to such reorganization within the meaning
     of Section 368(b) of the Code; and

          (ii)  no gain or loss will be recognized by Parent, Sub or the Company
     in the Merger.

     The opinions expressed herein are based upon existing statutory, regulatory
and judicial authority, any of which may be changed at any time with retroactive
effect.  In addition, our opinions are based solely on the documents that we
have examined, the additional information that we have obtained, and the
statements contained in the letters from Parent and the Company and certain
shareholders referred to above, which we have assumed are true on the date on
which the Merger is consummated.  Our opinions cannot be relied upon if any of
the facts pertinent to the Federal income tax treatment of the Merger stated in
such documents or in such additional information is, or later becomes,
inaccurate, or if any of the statements contained in the letters from Parent and
the Company and certain shareholders referred to above are, or later become,
inaccurate.  Our opinions are limited to the tax matters specifically covered
hereby, and we have not been asked to address, nor have we addressed, any other
tax consequences of the Merger.

     This opinion has been delivered to you for the purpose of satisfying the
conditions set forth in Section 5.1(e) of the Merger Agreement and is being
provided solely for your benefit; it may not be relied upon for any other
purpose or by any other person or entity, and may not be made available to any
other person or entity without our prior written consent.
