                             PLAN OF REORGANIZATION

        2.1 Conversion of Shares.

            2.1.1 Conversion of Sub Common Stock. At the Effective Time, each
share of the Common Stock of Sub that is issued and outstanding immediately
prior to the Effective Time will, by virtue of the Merger and without the need
for any further action on the part of the holder thereof, be converted into and
become one (1) share of SLC Common Stock that is issued and outstanding
immediately after the Effective Time, and the shares of SLC Common Stock into
which the shares of Sub Common Stock are so converted in the Merger will be the
only shares of capital stock of SLC that are issued and outstanding immediately
after the Effective Time.

            2.1.2 Conversion of SLC Common Stock. Subject to the terms and
conditions of this Agreement, at the Effective Time each share of SLC Common
Stock that is issued and outstanding immediately prior to the Effective Time
(other than any SLC Dissenting Shares as provided in Section 2.1.3) will, by
virtue of the Merger, and without the need for any further action on the part of
the holder thereof, be converted into the right to receive: (a) a number of
shares of HNC Common Stock that is equal to the SLC Share Conversion Number,
subject to the provisions of Section 2.2 regarding the elimination of fractional
shares; and (b) an amount of cash equal to the Closing Cash Amount Per Share,
subject to the provisions of Section 2.2 regarding the elimination of fractional
cents.

            2.1.3 SLC Dissenting Shares.

                (a) Notwithstanding anything in this Agreement to the contrary,
any shares of SLC capital stock held by any person or entity who has demanded
and perfected dissenters' appraisal rights with respect to such shares in
accordance with Section 262 of the DGCL and who, as of the Effective Time, has
not effectively released or forfeited such dissenters' appraisal rights ("SLC
DISSENTING SHARES") will not be converted into or represent the right to receive
shares of HNC Common Stock and cash pursuant to Section 2.1.2 in the Merger
(except as provided in Section 2.1.3(b)) and the holder of such shares shall
only be entitled to such appraisal rights as are granted to such holder under
the DGCL.

                (b) Notwithstanding the provisions of Section 2.1.3(a) above, if
any holder of shares of SLC Common Stock who demands the purchase of such shares
pursuant to Section 262 of the DGCL shall effectively release or forfeit such
holder's dissenters' appraisal rights (whether through failure to perfect such
rights or otherwise), then, effective as of the later of (i) the Effective Time
or (ii) the occurrence of such release or loss of such rights, such holder's
shares of SLC Common Stock shall cease to be SLC Dissenting Shares and shall
automatically be converted into and represent only the right to receive shares
of HNC Common Stock and cash as provided in Section 2.1.2, without interest
thereon, upon surrender of the certificate(s) representing such shares in
accordance with Article 7 of this Agreement, at which time such holder of such
shares


                                       6
<PAGE>   7

shall also become subject to the escrow provisions of Section 2.7 and the Escrow
Agreement.

                (c) SLC shall give HNC (i) prompt written notice of its receipt
of any written demands for purchase of any shares of SLC capital stock pursuant
to the dissenters' appraisal rights provisions of Section 262 of the DGCL, any
withdrawals of such demands, and any other instruments relating to the Merger
served pursuant to the DGCL and received by SLC and (ii) the opportunity to
participate (at HNC's expense) in all negotiations and proceedings with respect
to demands for purchase of any shares of SLC's capital stock under the DGCL. SLC
shall not, except with the prior written consent of HNC, which shall not be
unreasonably withheld, or as may be required under applicable law, voluntarily
make any payment with respect to any demands for the purchase of SLC capital
stock or offer to settle or settle any such demands.

        2.2 Fractional Shares and Fractional Cents.

            (a) Fractional Shares. No fractional shares of HNC Common Stock will
be issued in connection with the Merger. In lieu thereof, each SLC Stockholder
who would otherwise be entitled to receive a fraction of a share of HNC Common
Stock pursuant to Section 2.1.2, determined in each case after aggregating all
shares of HNC Common Stock to be received by such holder pursuant to Section
2.1.2, will instead receive from HNC, in lieu of any fractional share otherwise
issuable to such holder under Section 2.1.2, a payment of cash in an amount
equal to the product obtained by multiplying the HNC Closing Price Per Share (as
adjusted to reflect any Capital Change (as defined in Section 2.5 below) of HNC
occurring after the Agreement Date and prior to Effective Time) by the fraction
of a share of HNC Common Stock that such holder would otherwise be entitled to
receive, which amount shall be paid within ten (10) business days after the
Effective Time.

            (b) Fractional Cents. No fractional cents will be paid in connection
with the Merger. In lieu thereof, each SLC Stockholder who would otherwise be
entitled to receive payment in cash of a fractional cent pursuant to Section
2.1.2, determined after aggregating the total amount of cash payable to such SLC
Stockholder pursuant to Section 2.1.2, will have such fractional cent rounded
down to the nearest whole cent.

        2.3 Limitation on Number of HNC Shares Issued.

            (a) Notwithstanding anything in this Agreement (including but not
limited to this Section 2) to the contrary, in no event may the HNC Shares
Issuable (as defined below) exceed twenty percent (20%) of the number of shares
of HNC Common Stock that are issued and outstanding immediately prior to the
Effective Time. As used herein the "HNC SHARES ISSUABLE" means that number of
shares of HNC Common Stock that equals the sum of (a) the total number of shares
of HNC Common Stock that, but for the provisions of this Section 2.3, are to be
issued under the provisions of Section 2.1.2 of this Agreement, plus (b) the
total number of shares of HNC Common Stock that, but for the provisions of this
Section 2.3, are issuable upon the exercise of HNC Options to be issued under
Section 2.4 of this Agreement. If the HNC Shares Issuable shall at any time


                                       7
<PAGE>   8


exceed twenty percent (20%) of the number of shares of HNC Common Stock that are
issued and outstanding immediately prior to the Effective Time, then each of the
SLC Share Conversion Number and the SLC Option Conversion Number shall each be
proportionally reduced by the same ratio until the HNC Shares Issuable does not
exceed twenty percent (20%) of the number of shares of HNC Common Stock that are
issued and outstanding immediately prior to the Effective Time.

            (b) If, at the Closing, the SLC Share Conversion Number and the SLC
Option Conversion Number would be reduced pursuant to the provisions of
paragraph 2.3(a) above, then SLC shall have the option, by written notice to
HNC, to terminate this Agreement at any time prior to the Effective Time. If SLC
terminates this Agreement pursuant to this paragraph, the parties shall be
released from any further obligations hereunder other than obligations (such as
obligations of confidentiality) that would by their terms survive the
termination of this Agreement prior to closing.

        2.4 Assumption and Conversion of SLC Options.

            2.4.1 At Effective Time. At the Effective Time, each unexpired SLC
Option that is outstanding immediately prior to the Effective Time, whether or
not then exercisable, will by virtue of the Merger and this Agreement, and
without the need for any action on the part of the holder thereof, be assumed by
HNC and converted into an option to purchase shares of HNC Common Stock (an "HNC
OPTION") that (i) is exercisable (subject to the vesting conditions carried over
from such SLC Option as provided below) for that number of whole shares of HNC
Common Stock equal to the number of shares of SLC Common Stock that were subject
to such SLC Option immediately prior to the Effective Time multiplied by the SLC
Option Conversion Number, rounded down to the nearest whole number of shares of
HNC Common Stock, and (ii) has an exercise price per share of HNC Common Stock
equal to the exercise price per share of SLC Common Stock at which such SLC
Option was exercisable immediately prior to the Effective Time divided by the
SLC Option Conversion Number, rounded up to the nearest whole cent. The terms,
exercisability, vesting schedule, status as an "incentive stock option" under
Section 422 of the Code (if applicable) or as a nonqualified stock option, and
all other terms and conditions of each SLC Option (including but not limited to
the provisions of the SLC Stock Option Plan that form part of the terms and
conditions of such SLC Option) that is converted into an HNC Option pursuant to
this Section 2.4 will (except as otherwise provided in the terms of such SLC
Options, in Section 6.7 or under applicable law), to the extent permitted by law
and otherwise reasonably practicable, be unchanged and continue in effect after
the Merger with respect to such HNC Option and the shares of HNC Common Stock
issuable upon exercise thereof. Continuous employment or service with SLC prior
to the Effective Time will be credited to each holder of a SLC Option for
purposes of applying any vesting schedule contained in a SLC Option to determine
the number of shares of HNC Common Stock that are exercisable under the HNC
Option into which such SLC Option is converted in the Merger. HNC hereby accepts
at Closing the assignment of all rights of repurchase and all similar rights
under the SLC Stock Option Plan and any option grants or other agreements
entered into thereunder.



                                       8
<PAGE>   9


            2.4.2 Registration. HNC shall use its diligent good faith efforts to
cause the shares of HNC Common Stock issuable (but not yet issued) upon exercise
of the HNC Options that are issued by virtue of the conversion and assumption of
SLC Options under this Section 2.4 to be registered on a registration statement
on Form S-8 (or successor form) promulgated by the Securities and Exchange
Commission ("SEC") under the Securities Act of 1933, as amended (the "1933
ACT"), as soon as reasonably practicable after the Effective Time, and shall use
its best efforts to maintain the effectiveness of such registration statement or
registration statements for so long as such HNC Options remain outstanding and
HNC Common Stock is registered under the Securities Exchange Act of 1934, as
amended (the "1934 ACT"). Notwithstanding the foregoing, HNC shall have no
obligation to register any of such shares of HNC Common Stock with respect to
any HNC Option which is ineligible to be included in a registration statement on
Form S-8 under the 1933 Act.

        2.5 Adjustments for Capital Changes. Notwithstanding the provisions of
this Article 2, if at any time after the Agreement Date and prior to the
Effective Time, HNC recapitalizes, either through a subdivision (or stock split)
of its outstanding shares of Common Stock into a greater number of shares of
Common Stock, or a combination (or reverse stock split) of its outstanding
shares of Common Stock into a lesser number of shares, or reorganizes,
reclassifies or otherwise changes its outstanding shares of Common Stock, into
the same or a different number of shares of other classes of stock, either of
HNC or of another entity (other than through a subdivision or combination of
shares provided for in the previous clause), or declares a dividend on its
outstanding shares of Common Stock payable in shares of HNC Common Stock (each,
a "CAPITAL CHANGE"), then the HNC Closing Price Per Share, the SLC Share
Conversion Number, and the SLC Option Conversion Number, will each, if and to
the extent necessary, be appropriately adjusted so as to equitably maintain the
proportionate interests of the stockholders of HNC and SLC intended by this
Agreement (but, in the case of stockholders of SLC, only with respect to their
interests in the equity of HNC represented by those shares of HNC Common Stock
and HNC Options that are issued pursuant to the Merger and this Agreement.)
Notwithstanding the foregoing, the provisions of this Section 2.5 shall not
apply to the Retek Dividend, which shall occur after the Effective Time. The
effects of the Retek Dividend are addressed in Section 6.7.

        2.6 Continuation of Vesting and Repurchase Rights. If any shares of SLC
Common Stock that are outstanding immediately prior to the Effective Time (a)
are subject to a repurchase option (other than a right of first refusal), risk
of forfeiture, or other condition providing that such shares may be forfeited or
repurchased by SLC upon any termination of the stockholder's employment,
directorship, consultancy or other relationship with SLC (and/or any affiliate
of SLC) under the terms of any restricted stock purchase agreement or other
agreement with SLC that does not by its terms provide that such repurchase
option, risk of forfeiture or other condition lapses automatically upon
consummation of the Merger ("UNVESTED SLC SHARES") or (b) are subject to a
contractual restriction on the transfer of such shares, other than a right of
first refusal ("RESTRICTED SLC SHARES"), then the shares of HNC Common Stock
issued upon the conversion of such Unvested SLC Shares or Restricted SLC Shares
in the Merger will continue to be unvested and will continue to be subject to
the same repurchase options,


                                       9
<PAGE>   10

risks of forfeiture, restrictions on transfer (other than a right of first
refusal) or other conditions, as applicable, immediately following the Effective
Time as they were subject to immediately prior to the Effective Time and the
certificates representing such shares of HNC Common Stock shall accordingly be
marked with appropriate legends noting such repurchase options, risks of
forfeiture, restrictions on transfer or other conditions. SLC shall use
reasonable efforts to take all actions that may be necessary to ensure that,
from and after the Effective Time, HNC is entitled to exercise any such

this Agreement (the "SLC DISCLOSURE LETTER"), each of the representations,
warranties and statements contained in the following sections of this Article 3

and warranties made and given by SLC under Article 3 of this Agreement.

        3.1 Organization and Good Standing. SLC is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware.
SLC has the corporate power and authority to own, operate and lease its
properties and to carry on its business as now conducted and as proposed to be
conducted, and is qualified to transact business, and is in good standing, as a
foreign corporation in each jurisdiction in which its failure to be so qualified
would have a Material Adverse Effect on SLC. SLC has delivered to HNC or its
counsel, Fenwick & West LLP, true and correct copies of SLC's currently
effective Certificate of Incorporation and Bylaws, each as amended to date. SLC
is not in violation of its Certificate of Incorporation, Bylaws or other charter
documents. All of the members of SLC's Board of Directors have been validly and
lawfully elected to SLC's Board of Directors.

        3.2 Subsidiaries. SLC has no subsidiaries. SLC does not have any equity
or ownership interest, whether direct or indirect, in any corporation,
partnership, limited partnership, limited liability company, joint venture or
other business entity other than Fraudlink, LLC ("FRAUDLINK"). SLC has delivered
to HNC or its counsel true and correct copies of the currently effective written
agreements or charter documents governing Fraudlink, including without
limitation the Fraudlink Operating Agreement (as defined below). Fraudlink is a
limited liability company organized and in good standing under the laws of the
State of New Jersey. The only members of Fraudlink are SLC and National Fraud

Letter also describes in detail the basis for any change in the royalty rates
under the LLC License Agreement and the effective date of each such change in
the royalty rate. Schedule 3.2 to the SLC Disclosure Letter also specifies the
date on which

each such new version, modification or enhancement. No consent of Timothy Kear,
James Oviedo, Christopher Cordes or Foundation Group, Inc was required in
connection with the LLC License Agreement or is required in connection with SLC
entering into and performing this Agreement. The execution delivery and
performance of the LLC License Agreement did not, and the execution, delivery
and performance of this Agreement will not, breach, with or without notice or
passage of time, the terms and provisions of the LLC Operating Agreement or that
certain Asset Purchase Agreement dated April 30, 1998 by and between NFC and
Messrs. Kear, Oviedo and Cordes and Foundation Group, Inc. (the "ASSET PURCHASE

        3.4 Capitalization of SLC.

            3.4.1 Capital Stock.

                (a) Authorized and Outstanding Shares. The authorized capital
stock of SLC consists entirely of 25,000,000 shares of Common Stock, $0.001 par
value per share, of which a total of 8,671,083 shares are issued and
outstanding. No fractional shares of SLC Common Stock are issued or outstanding.
SLC holds 3,664,122 treasury shares. No shares of any preferred stock of SLC
are, or ever have been, authorized, issued or outstanding.

                (b) Status of Shares. All of the issued and outstanding shares
of SLC's capital stock have been duly authorized and validly issued, are fully
paid and nonassessable, are not subject to any claim, lien, preemptive right,
right of first refusal, right of first offer or right of rescission, and have
been offered, issued, sold and delivered by SLC in compliance with all
registration or qualification requirements (or applicable exemptions therefrom)
of all applicable federal and state securities laws. No stockholder of SLC owes
SLC any money or other consideration representing any part of the purchase price
of any outstanding shares of SLC's capital stock, including without limitation
any money due under a promissory note payable to SLC. SLC has no liability (or
potential liability) to any stockholder (or former stockholder) for any
dividends that have been declared or accrued or for any portion of any
repurchase or redemption price payable to such stockholder (or former
stockholder) to repurchase or redeem any of the stockholder's shares of SLC
capital stock.

                (c) Stockholders. A list of all holders of SLC's outstanding
capital stock, and the total number of shares of (and share certificate numbers
for) SLC Common Stock owned by each such holder is set forth in Schedule 3.4.1
to the SLC Disclosure Letter (the "SLC STOCKHOLDER LIST"). No issued and
outstanding shares of SLC Common Stock are subject to an option held by SLC to
purchase any of such shares at their original issuance price upon the
termination of employment or other services with SLC of the holder of such
shares.

            3.4.2 Options, Warrants and Rights.

                (a) Outstanding Options, Warrants and Rights. Except for SLC
Options to purchase an aggregate total of 489,500 shares of SLC Common Stock
that are outstanding on the Agreement Date, all of which options were granted
under the SLC Stock Option Plan, all as more fully described in Schedule 3.4.2
to the SLC Disclosure Letter, there are no SLC Derivative Securities, calls,
commitments, conversion privileges, preemptive rights, rights of first refusal,
rights of first offer or other rights or agreements outstanding to purchase or
otherwise acquire from SLC (whether directly or indirectly) any shares of SLC's
authorized but unissued capital stock or any securities convertible into or
exchangeable for any shares of SLC's capital stock or obligating SLC to grant,
issue, extend, or enter into any SLC Derivative Securities, call, commitment,
conversion privilege, preemptive right, right of first refusal, right of first
offer or other such right or agreement. Except for the SLC Options described
above in


                                       16
<PAGE>   17


this Section 3.4.2(a), no options, warrants, convertible debentures, or any
other securities of SLC or rights to acquire shares of SLC stock or any other
securities of SLC will become an option, warrant, convertible debenture,
security or other right to purchase or otherwise acquire from SLC any capital
stock or other securities of HNC, or any other obligation or liability of HNC,
by reason of the Merger or this Agreement. To SLC's knowledge, no person or
entity holds, or has any option, warrant or other right to acquire, any issued
and outstanding shares of the capital stock of SLC or SLC Derivative Securities
from any holder of shares of the capital stock of SLC.

                (b) Status of SLC Stock Plans. A total of 1,000,000 shares of
SLC Common Stock are reserved for issuance under the SLC Stock Option Plan. As
of the Agreement Date: (i) no shares of SLC Common Stock have been issued under
the SLC Stock Option Plan or are outstanding under the SLC Stock Option Plan;
(ii) a total of 489,500 shares of SLC Common Stock are potentially issuable upon
the exercise of all options granted under the SLC Stock Option Plan that are
outstanding on the Agreement Date; and (iii) a total of 510,500 shares of SLC
Common Stock are reserved and available for issuance under the SLC Stock Option
Plan and are not yet outstanding nor subject to outstanding SLC Options. As of
the Agreement Date, each SLC Non-Plan Grant has been exercised in full and no
options are outstanding under any SLC Non-Plan Grant. Except as set forth on
Schedule 3.4.2 to the SLC Disclosure Letter, no SLC Options contain any
provisions accelerating the vesting of the right to exercise such SLC Options
upon or as a result of the Merger, this Agreement or any other merger or
consolidation involving SLC, any issuance or sale of SLC stock, any sale of all
or substantially all of SLC's assets or any business combination or similar
transaction involving or causing a change of control of SLC ("ACCELERATED
VESTING ON CHANGE OF CONTROL PROVISIONS"). The SLC Stock Option Plan and any
change that has been made to (i) the number of shares reserved under the SLC
Stock Option Plan or (ii) the eligible participants under the SLC Stock Option
Plan, have each been duly and validly approved by SLC's Board of Directors and
by SLC's stockholders to the extent required by applicable law, and such
stockholder approval was obtained as required by the SLC Stock Option Plan and
within one (1) year of the date on which such SLC Stock Option Plan (or such
change) was approved by SLC's Board of Directors. The provisions of Section 2.4
(regarding the assumption and conversion of SLC Options in the Merger) are, and
at the Effective Time will be, binding and enforceable against each holder of a
SLC Option that is outstanding immediately prior to the Effective Time. The
exercise price at which each SLC Option may be exercised was the fair market
value of SLC's Common Stock, as determined in good faith by SLC's Board of
Directors, on the date such SLC Option was granted. All outstanding SLC Options
that have designated by SLC as "incentive stock options" fully qualify as
incentive stock options within the meaning of Section 422 of the Code. SLC has
no outstanding stock options not granted under either an SLC Non-Plan Grant or
the SLC Stock Option Plan. SLC has no stock option, stock incentive or stock
purchase plans other than the SLC Stock Option Plan. No individual who is an
employee, consultant or other service provider to Fraudlink holds an SLC Option,
unless such individual is also an employee of SLC.

                (c) Holders of Options and Warrants. Attached as Schedule 3.4.2
to the SLC Disclosure Letter is (i) a true and complete list of all SLC Options
that


                                       17
<PAGE>   18


are outstanding on the Agreement Date, all of which have been granted under the
SLC Stock Option Plan, setting forth the holder of each such SLC Option, whether
such individual is an employee, consultant, or director of SLC, the date of
grant, the exercise price per share at which SLC Common Stock is purchasable
under such SLC Option, the vesting schedule of each such SLC Option as of
immediately following the Effective Time, the number of shares of SLC Common
Stock subject to each such SLC Option, and whether or not SLC has designated
such SLC Option as an incentive stock option within the meaning of Section 422
of the Code; and (ii) a true and complete list of all other securities or rights
to purchase or otherwise acquire any shares of the capital stock of SLC of any
class or series, identifying such rights and any conditions to the exercise
thereof, the holders thereof and the number, class and series of such shares of
SLC capital stock issuable thereunder (Schedule 3.4.2 to the SLC Disclosure
Letter is hereinafter referred to as the "SLC OPTION HOLDER LIST"). Schedule
3.4.2 also includes a true and complete list of all outstanding securities or
rights to purchase or otherwise acquire securities or equity or economic
interests in Fraudlink, identifying such rights and any conditions to the
exercise thereof, the holders thereof and the number, class and series of such
shares or equity or economic interests.

            3.4.3 No Voting Arrangements, Registration Rights. There are no
voting agreements, voting trusts, proxies, preemptive rights, rights of first
refusal, rights of first offer, rights of co-sale or tag-along rights, put or
option arrangements, buy-sell agreements or redemption agreements obligating
SLC, or allowing any party, to redeem or repurchase any shares of its capital
stock under any conditions or other restrictions applicable to any shares of
SLC's outstanding stock or other securities or to the conversion of any shares
of SLC's capital stock in the Merger pursuant to any agreement or obligation to
which SLC is a party or, to SLC's knowledge, pursuant to any other agreement or
obligation. SLC has no obligation to register under the 1933 Act any of its
presently outstanding shares of stock or other securities or any stock or other
securities that may subsequently be issued by SLC. The Redemption/Cross-Purchase
Agreement, dated October 23, 1985, as amended, by and between SLC, Robert E.
Bruneau, Dubi Silverstein and Joseph R. Lagae (the "REDEMPTION AGREEMENT"), was
validly and completely terminated effective October 6, 1998 and no conditions to
such termination remain unsatisfied. No sales of securities of SLC were made in
violation of the Redemption Agreement.

        3.5 No Conflict. Neither the execution and delivery of this Agreement
nor any of the SLC Ancillary Agreements by SLC, nor the consummation of the
Merger or any of the other transactions contemplated hereby or thereby, will
conflict with, or (with or without notice or lapse of time, or both) result in a
termination, breach, impairment or violation by SLC of: (i) any provision of the
Certificate of Incorporation or Bylaws or other charter documents of SLC as
currently in effect; (ii) any federal, state, local or foreign law, statute,
rule, regulation, judgment, writ, decree or order, applicable to SLC or any of
its assets or properties (including but not limited to the DGCL) or, to SLC's
knowledge, any of its officers, key employees or key consultants; or (iii) any
Material SLC Agreement (as defined in Section 3.11). Neither SLC's entering into
this Agreement nor the consummation of the Merger will give rise to, or trigger
the application of, any rights of any third party that would come into effect
upon the


                                       18
<PAGE>   19

effectiveness of the Merger. The consummation of the Merger or any other
transaction contemplated by this Agreement by SLC will not require the consent,
release, waiver or approval of any third party other than the required approval
of SLC's stockholders under the DGCL (which consent and approval has been
obtained by a unanimous written consent of SLC's stockholders in compliance with
the DGCL, including without limitation Section 228 of the DGCL). Except as set
forth in Schedule 3.5 to the SLC Disclosure Letter, no consent or approval of
any third party is required to ensure that, following the Effective Time, any
SLC Material Agreement will continue to be in full force and effect without any
breach, default or violation thereof caused by virtue of the Merger or by any
other transaction called for by this Agreement or any SLC Ancillary Agreement.

        3.6 Litigation. There is no action, claim, suit, arbitration, mediation,
proceeding or investigation pending against SLC or Fraudlink (or, to SLC's
knowledge, against any officer, director, employee, key consultant or agent of
SLC or Fraudlink in their capacity as such or relating to their employment,
services or relationship with SLC or Fraudlink) before any court, administrative
agency or arbitrator, nor, to SLC's knowledge, has any such action, suit,
proceeding, arbitration, mediation, claim or investigation been threatened.
There is no judgment, decree, injunction, rule or order of any governmental
entity or agency, court or arbitrator outstanding against SLC or Fraudlink or,
to SLC's or Fraudlink's knowledge, against any officer, director, employee, key
consultant or agent of SLC or Fraudlink in their capacity as such. There is no
basis for any person, firm, corporation or other entity to assert a claim
against SLC or Fraudlink based upon: (a) SLC's entering into this Agreement or
any SLC Ancillary Agreement or consummating the Merger or any of the
transactions contemplated by this Agreement or any SLC Ancillary Agreement
(other than claims asserting dissenters' appraisal rights under Section 262 of
the DGCL, if any are made or can be made); or (b) a disputed claim of ownership
of options, warrants or other rights to acquire ownership of, any shares of the
capital stock of SLC or any rights as a SLC stockholder, including any option,
warrant or preemptive rights, right of refusal, rights of co-sale or tag along
rights or rights to notice or to vote.

        3.7 Taxes.

            3.7.1 SLC and Fraudlink have each timely filed all federal, state,
local and foreign tax returns required to be filed by it, has timely paid all
taxes required to be paid by it for which payment is due, has established an
adequate accrual or reserve for the payment of all taxes payable in respect of
the periods subsequent to the periods covered by its most recent applicable tax
returns (which accrual or reserve as of the Balance Sheet Date (as defined in
Section 3.8 below) is fully reflected on the Balance Sheet (as defined in
Section 3.8 below), have each made all necessary estimated tax payments, and has
no material liability for taxes in excess of the amount so paid or accruals or
reserves so established. Neither SLC nor Fraudlink is delinquent in the payment
of any tax or in the filing of any tax return, and no deficiencies for any tax
have been threatened, claimed, proposed or assessed against SLC, Fraudlink, or
any of the officers, employees or agents of SLC or Fraudlink in their capacity
as such. Neither SLC nor Fraudlink have received any notification that any
material issues have been raised by (or are currently pending)


                                       19
<PAGE>   20

before the Internal Revenue Service or any other taxing authority (including but
not limited to any sales or use tax authority) regarding SLC or Fraudlink and no
tax return of SLC or Fraudlink has ever been audited by the Internal Revenue
Service or any state or local taxing agency or authority. No tax liens have been
filed against any assets of SLC or Fraudlink. SLC is not, and since its
inception has not been, a "personal holding company" within the meaning of the
Code. SLC has not filed any election under Section 341(f) of the Code. SLC and
Fraudlink have each withheld with respect to each of its employees and
independent contractors all taxes, including but not limited to federal and
state income taxes, FICA, Medicare, FUTA and other taxes, required to be
withheld, and paid such withheld amounts to the appropriate tax authority within
the time prescribed by law. Without in any way limiting the generality of the
preceding sentence and the preceding provisions of this Section 3.7.1, SLC has
withheld with respect to each person who has exercised a non-qualified option to
purchase shares of SLC capital stock granted by SLC (including without
limitation each former holder of an SLC Non-Plan Grant who has exercised an
option under a SLC Non-Plan Grant, and has received payment in full from each
former holder of an SLC Non-Plan Grant) all taxes, including but not limited to
federal and state withholding taxes required to be withheld, and paid such
withheld amounts to the appropriate tax authority (except for any employer
Medicare tax obligations, which shall be paid by the Surviving Corporation).

            3.7.2 Effective as of February 1, 1997, SLC made a valid election
under Section 1362 of the Code and any corresponding state or local tax
provision to be an S corporation within the meaning of Sections 1361 and 1362 of
the Code effective for all taxable periods beginning on or subsequent to
February 1, 1997. At no time on or after February 1, 1997, including up through
and including the Effective Time, has or will SLC experience any of the
following: (1) any corporate level tax event under Section 1374 or any other
provision of the Code; or (2) any type or form of voluntary, involuntary or
inadvertent termination of its S corporation status other than the termination
that will take place as a result of the Merger. SLC and the SLC Stockholders
since February 1, 1997, have at no time taken any action or tax return position
inconsistent with the treatment of SLC as an S corporation from February 1, 1997
through the Agreement Date. Similarly, neither SLC nor any of the SLC
Stockholders have, at any time on or after February 1, 1997 through the
Effective Time, failed at any time to take any action required in order to
maintain SLC's S corporation status under the Code or any other tax law.
Schedule 3.7.2 sets forth each state and locality where SLC has made a valid
election under the applicable law of such jurisdiction to be an S corporation
effective for all taxable periods beginning on or subsequent to the date of such
election, and the date of such election.

            3.7.3 SLC has documentary evidence of its S corporation election
from the Internal Revenue Service (and other relevant taxing authorities), and
SLC shall deliver such documents along with the other Tax records of SLC to HNC
as part of the transactions contemplated by this Agreement.

            3.7.4 For the purposes of this Section, the terms "TAX" and "TAXES"
include all federal, state, local and foreign income, alternative or add-on
minimum income, gains, franchise, excise, property, property transfer, sales,
use, employment,


                                       20

license, payroll, ad valorem, documentary, stamp, withholding, occupation,
recording, value added or transfer taxes, governmental charges, fees, customs
duties, levies or assessments (whether payable directly or by withholding), and,
with respect to any such taxes, any estimated tax, interest, fines and penalties
or additions to tax and interest on such fines, penalties and additions to tax.

        3.8 SLC Financial Statements. SLC has delivered to HNC, as Schedule 3.8
to the SLC Disclosure Letter, (a) the audited consolidated balance sheets of SLC
as of December 31, 1997, December 31, 1998 and December 31, 1999 and SLC's
audited consolidated statements of operations, statements of cash flows and
statements of changes in stockholders' equity for each of the fiscal years ended
December 31, 1997, December 31, 1998 and December 31, 1999 and (b) the unaudited
consolidated balance sheet of SLC as of July 31, 30, 2000 and SLC's unaudited
consolidated statement of operations for its six months ended July 31, 2000 (all
such audited and unaudited financial statements of SLC and any notes thereto are
hereinafter collectively referred to as the "SLC FINANCIAL STATEMENTS"). The SLC
Financial Statements (a) are derived from and in accordance with the books and
records of SLC, (b) fairly present the financial condition of SLC at the dates
therein indicated and the results of operations for the periods therein
specified and (c) have been prepared in accordance with generally accepted
accounting principles applied on a basis consistent with prior periods (except,
solely in the case of any of such SLC Financial Statements that are unaudited,
for any absence of notes thereto and the absence of year-end audit adjustments).
SLC has no material debt, liability or obligation of any nature, whether
accrued, absolute, contingent or otherwise, and whether due or to become due,
except for (i) those shown on SLC's unaudited balance sheet as of July 31, 2000
that is included in the SLC Financial Statements (the "BALANCE SHEET"), and (ii)
those that may have been incurred after July 31, 2000 (the "BALANCE SHEET DATE")
in the ordinary course of SLC's business consistent with its past practices, and
that are not material in amount, either individually or collectively, and are
not required to be set forth in the Balance Sheet under GAAP. All reserves
established by SLC that are set forth in or reflected in the Balance Sheet are
reasonably adequate. At the Balance Sheet Date, there were no material loss
contingencies (as such term is used in Statement of Financial Accounting
Standards No. 5 issued by the Financial Accounting Standards Board in March
1975) that are not adequately provided for in the Balance Sheet as required by
said Statement No. 5. SLC's total assets (determined in accordance with GAAP) do
not, as of the Agreement Date or the last regularly prepared balance sheet of
SLC prepared prior to the Effective Time, and will not, as of the Effective
Time, equal or exceed Ten Million Dollars ($10,000,000).

        3.9 Title to Properties. SLC and Fraudlink have good and marketable
title to all of their respective assets and properties (including but not
limited to those shown on the Balance Sheet), free and clear of all mortgages,
deeds of trust, security interests, pledges, liens, title retention devices,
collateral assignments, claims, charges, restrictions or other encumbrances of
any kind other than Permitted Encumbrances. All machinery, vehicles, equipment
and other tangible personal property owned or leased by SLC and Fraudlink or
used in its business are in reasonably good condition and repair, normal wear
and tear excepted. All leases of real or personal property to which SLC or
Fraudlink is a party are fully effective and afford SLC or Fraudlink, as
applicable, a valid


                                       21
<PAGE>   22


leasehold interest in, and the right to peaceful and undisturbed leasehold
possession of, the real or personal property that is the subject of the lease.
To SLC's knowledge, neither SLC nor Fraudlink is in violation of any zoning,
building, safety or environmental ordinance, regulation or requirement or other
law or regulation applicable to the operation of its owned or leased properties,
nor has SLC received any notice of violation of law with which it has not
complied. Neither SLC nor Fraudlink owns any real property.

        3.10 Absence of Certain Changes. Since the Balance Sheet Date, there has
not been with respect to SLC or Fraudlink any:

after the Balance Sheet Date;

            (f) purchase, license, sale, assignment or other disposition or

course of SLC's or Fraudlink's business, consistent with its past practices;

            (g) damage, destruction, theft or loss of any property or asset of

or otherwise in the ordinary course of SLC's business, consistent with its past
practices and not in conflict with any of the provisions of this Agreement or
any of the conditions contained in Article 8 or Article 9 of this Agreement;

            (j) the entering into, amendment of, relinquishment, termination or

practices or as may be expressly required by the terms of this Agreement;

            (k) entering into by SLC or Fraudlink of any transaction, contract

Agreement, the Certificate of Merger, nor the consummation of the Merger and the

means the record date for determining those stockholders of SLC who are entitled
to vote by written consent in connection with the SLC Stockholders' Vote.

        3.24 No Existing Discussions. Neither SLC nor any director, officer,
stockholder, employee or agent of SLC is engaged, directly or indirectly, in any
discussions or negotiations with any third party relating to any transaction

business combination transaction involving SLC.

arising prior to and including August 31, 1998, against SLC and its officers,
directors, stockholders and their respective successors and assigns (the
"BRUNEAU RELEASED CLAIMS"). Except for the payment of the total sum of
$1,400,000 owing to Bruneau as of the Agreement Date and payable within 30 days
of the Closing (which $1,400,000 is the exact, correct and entire amount that
will remain payable from SLC to Bruneau as of the Effective Time), neither SLC
nor any of its officers, directors or stockholders (in their capacities as such)
shall have an obligation to pay any sum to Bruneau as of the Closing Date or
following the Closing Date in connection with the Bruneau Released Claims and
Bruneau's status as a former stockholder, director and officer of SLC or for any
other reason or cause. SLC has provided HNC with the Settlement Agreement, dated
August 31, 1998, between SLC, Bruneau, Diane E. Sammer, Dubi Silverstein and
Steven J. Carras, and all releases, instruments, agreements, dismissals and
orders required to be entered into, executed and obtained thereunder, none of
which have been amended, modified, released or cancelled.

of SLC or Fraudlink in connection with the Merger or the consummation of the
transactions contemplated by this Agreement.

            (a) Neither this Agreement, its exhibits and schedules and the SLC
Disclosure Letter, nor any of the certificates or documents to be delivered by
SLC to HNC under this Agreement, taken together, contains any untrue statement
of a material fact or omits to state any material fact necessary in order to

of 120,000,000 shares of HNC Common Stock, $0.001 par value per share, and
4,000,000 shares of Preferred Stock, $0.001 par value per share (the "HNC
PREFERRED STOCK"). At the close of business on September 1, 2000, 29,210,560
shares of HNC Common Stock were issued and outstanding and 619 shares of HNC
Common Stock were issued and held in HNC's treasury. No shares of HNC Preferred
Stock are issued or outstanding. All issued and outstanding shares of HNC Common
Stock have been duly authorized and validly issued, are fully paid and
nonassessable and not subject to preemptive rights. As of the date hereof, the
authorized capital stock of Sub consists of 100 shares of Common Stock, $0.001
par value per share, of which 100 shares have been duly authorized and validly

prior to the Effective time will, upon effectiveness of the Retek Dividend, be
adjusted to reflect the Retek Dividend. As of August 31, 2000, there were
outstanding $17,167,000 in principal face amount of 4.75% Convertible
Subordinated Notes due 2003 of HNC, which, as of the Agreement Date, are
convertible into shares of HNC Common Stock at the price of $44.85 per share of
HNC Common Stock, as presently constituted (the "CONVERTIBLE NOTES") subject to
adjustment of such conversion price to reflect the Retek Dividend.

        4.4 No Violation of Material Agreements. Neither the execution and
delivery of this Agreement nor any HNC Ancillary Agreement, nor the consummation
of the transactions contemplated by this Agreement or any HNC Ancillary
Agreement, will conflict with, or (with or without notice or lapse of time, or
both) result in: (a) a breach, impairment or violation of (i) any provision of
the Certificate of Incorporation or Bylaws of HNC, as currently in effect or

statute, rule or regulation to which HNC or its assets or properties is subject;

Retek's common stock (all such documents described in the foregoing clauses (a)
through (j) above being collectively hereinafter referred to as the "HNC
DISCLOSURE PACKAGE"). The HNC Disclosure Package, this Agreement, the exhibits
and schedules hereto, and any certificates or documents to be delivered by HNC
to SLC pursuant to this Agreement, when taken together, did not, as of their
respective filing dates, contain any untrue statement of a material fact or omit
to state any material fact necessary in order to make the statements contained

suit, arbitration, mediation, proceeding, claim or investigation pending (or, to
HNC's knowledge, threatened) against HNC before any court, administrative agency
or arbitrator that, if determined adversely to HNC, is likely to have a Material
Adverse Effect on HNC's financial condition or results of operation.

        4.9 Retek Stock. To HNC's knowledge, as of the Agreement Date, Retek
does not presently intend to place any restrictive legends on the certificates
for the shares of Retek Common Stock that the SLC Stockholders would receive in
the Retek Dividend if they are holders of record of HNC Common Stock on the
record date for the Retek Dividend, or to impose restrictions on transfer on
such shares.

substantial portion of SLC's business, assets or capital stock, whether by way
of merger, consolidation, sale of assets, sale of stock, tender offer and/or any

in making available all financial information reasonably requested by HNC,
including


                                       46
<PAGE>   47


without limitation the right to examine all working papers pertaining to all
financial statements prepared or audited by such accountants.

        5.11 Satisfaction of Conditions Precedent. SLC will use its diligent
efforts to satisfy or cause to be satisfied all the conditions precedent that
are set forth in Articles 8 and 9, and SLC will use its best efforts to cause
the Merger and the other transactions contemplated by this Agreement to be
consummated in accordance with the terms of this Agreement by the Termination
Date.

        5.12 Blue Sky Laws. SLC will use diligent efforts to assist HNC to the
extent necessary to comply with the securities and Blue Sky laws of all
jurisdictions that are applicable in connection with the Merger. HNC shall bear
the expense of such compliance if the Merger is consummated.

        5.13 SLC Dissenting Shares. As promptly as practicable after the date of
SLC Stockholders' Vote and prior to the Closing Date, SLC will furnish HNC with
the name and address of each holder (or potential holder) of any SLC Dissenting
Shares (if any) and the number of SLC Dissenting Shares (or potential SLC
Dissenting Shares) owned by each such holder.

        5.14 SLC Employee Plans and Benefit Arrangements. SLC shall terminate
any SLC Benefit Arrangement that is governed by Section 401(k) of the Code
immediately prior to the Effective Time upon the request of HNC. SLC shall take
such steps as are necessary to ratify the termination of the Simplified Employee
Pension Individual Retirement Account Plan and the steps that were taken in
connection with such termination to ensure that there is no continuing liability
to the Surviving Corporation or HNC in connection with the termination of same.
In the event that the distribution or rollover of assets from the trust of a
Code Section 401(k) plan that is terminated will trigger liquidation, surrender
or other fees that will be imposed on the terminated plan or any participant or
beneficiary of such terminated plan, SLC shall take such actions as are
necessary to reasonably estimate the amount of such fees and provide such
reasonable estimate in writing to HNC prior to the Effective Time. SLC shall
file any delinquent Form 5500s through the Department of Labor Delinquent Filer
Voluntary Compliance Program prior to the Effective Time.

        5.15 Closing of Merger. SLC will not refuse to effect the Merger if, on
or before the Closing Date, all the conditions precedent to SLC's obligations to
effect the Merger under Article 8 have been satisfied or waived by SLC and HNC
elects to consummate the Merger.

        5.16 SLC's Borrowing Authority for Permitted Bonus. SLC may, at any time
prior to the Effective Time, borrow from Commerce Bank up to an aggregate
principal amount of Two Million Dollars ($2,000,000) solely for the purpose
provided herein (the "PERMITTED LOAN"), but only if and to the extent that SLC
shall use the proceeds of such Permitted Loan on the day before the Effective
Time solely to pay cash bonuses to certain of SLC's employees in the aggregate
amount not to exceed Two Million Dollars ($2,000,000) with the amount of such
bonus that is paid to each such SLC employee to be


                                       47
<PAGE>   48

approved by HNC (the "PERMITTED BONUS"). The Permitted Loan shall have a
maturity date after the Effective Time and contain no restrictions or premiums
on prepayment or prepayment penalties and the terms and conditions of such
Permitted Loan shall have been previously approved in writing by HNC, which
shall not be unreasonably withhold, delay or place conditions on its approval.
Notwithstanding anything in this Agreement to the contrary, (i) SLC shall not be
deemed to be in default of its obligations under this Agreement by reason of the
existence of such Permitted Loan at Closing and (ii) no representation or
warranty of SLC shall be deemed to be untrue or incorrect as a result of the
existence of the loan at Closing, or as a result of SLC's failure to disclose
such loan.

                                    ARTICLE 6
                                  HNC COVENANTS

        6.1 Advice of Changes. During the time period from the Agreement Date
until the earlier to occur of (i) the Effective Time or (ii) the termination of
this Agreement in accordance with Article 10, HNC will promptly advise SLC (a)
of any event occurring subsequent to the Agreement Date of which HNC has
knowledge that would render any representation or warranty of HNC contained in
Article 4 of this Agreement (as qualified by the HNC Disclosure Letter), if made
on or as of the date of such event or the Closing Date, untrue or inaccurate in
any material respect and (b) of any Material Adverse Change in HNC arising after
the Agreement Date and prior to the Effective Time.

        6.2 Regulatory Approvals. HNC will promptly execute and file, or join in
the execution and filing, of any application, notification or any other document
that may be necessary in order to obtain the authorization, approval or consent
of any Governmental Authority, whether federal, state, local or foreign, which
may be reasonably required, in connection with the consummation of the Merger
and the other transactions contemplated by this Agreement and the HNC Ancillary
Agreements and Sub Ancillary Agreements in accordance with the terms of this
Agreement. HNC will use diligent efforts to obtain all such authorizations,
approvals and consents.

        6.3 Satisfaction of Conditions Precedent. HNC will use its diligent
efforts to satisfy or cause to be satisfied all of the conditions precedent
which are set forth in Article 8, and HNC will use its diligent efforts to cause
the Merger and the other transactions contemplated by this Agreement to be

Date.

        6.4 Employee Benefits. HNC and/or Surviving Corporation shall, as of the
Effective Time of the Merger, adopt and maintain those SLC Benefit Arrangements
(as such term is defined in Section 3.16.4 hereof) that constitute health,
dental and vision plans, programs or arrangements (the "HEALTH, DENTAL AND
VISION PLANS") in effect immediately prior to the Effective Time of the Merger
and, accordingly, shall thereby continue in full force and effect each such
Health, Dental and Vision Plan subject to the terms and conditions thereof until
December 31, 2000. After that date, HNC may either continue those Health, Dental
and Vision Plans or provide all active employees of SLC and their dependents
coverage (the "COVERAGE") under one or more employee benefit plans of HNC and/or
Surviving Corporation (the "SUBSTITUTED PLANS"), including without


                                       48
<PAGE>   49

limitation, health coverage, which meets the following requirements: (A) the
Coverage is substantially similar in the aggregate to the coverage provided to
HNC employees under HNC employee benefit plans, (B) service with SLC and each of
its subsidiaries prior to the Effective Time of the Merger shall be credited
against all service and waiting period requirements under the Substituted Plans,
and (C) the Coverage shall not provide any pre-existing condition exclusions to
the extent provided under such Substituted Plans. If HNC so requests, SLC shall
terminate all employee pension benefit plans, within the meaning of Section 3(2)
of ERISA prior to the Closing, provided that HNC offers employees covered by
such plans prior to the Closing the opportunity to participate in the HNC
Software Inc. Section 401(k) Plan following the Closing.

        6.5 Repayment of SLC Indebtedness. HNC agrees, promptly and in all
events within two (2) business days after the Effective Time, to pay One Million
Four Hundred Thousand Dollars ($1,400,000) to Robert E. Bruneau under the
Bruneau Settlement Agreement (or such lesser sum as is then owing to Mr. Bruneau
under the Bruneau Settlement Agreement). HNC shall make that payment to Mr.
Bruneau by check. HNC also agrees, within two (2) business days after the
Effective Time, to (i) repay, in full in cash, or (ii) make effective provision
for the removal as guarantor(s) at Closing of Diane E. Sammer and Dubi
Silverstein with respect to, the SLC Indebtedness set forth in Schedule 6.5 in a
maximum aggregate amount of $4,300,000 (inclusive of all accrued interest and
other fees, costs and charges); provided that SLC shall first have satisfied the
conditions set forth in Section 9.15.

        6.6 Retek Dividend.

            (a) HNC shall ensure that the record date for determining the HNC
stockholders who are entitled to receive the Retek Dividend shall be a date
after the Effective Time.

            (b) The treatment of HNC Options issued pursuant to the Merger in
connection with the Retek Dividend shall be as described in this Section 6.6(b).
HNC shall adjust, in accordance with GAAP, the exercise price of each HNC Option
that is outstanding immediately following the date the Retek Dividend is paid
(the "EXERCISE PRICE ADJUSTMENT DATE") using the methodology used to adjust the
exercise price of the outstanding options to purchase HNC Common Stock that are
now held by employees of HNC with respect to the Retek Dividend. Any HNC Option
that is exercised prior to the Exercise Price Adjustment Date shall not be
entitled to the exercise price adjustment described in this Section 6.6. To
maintain the intrinsic value of each HNC Option that is outstanding and unvested
on the record date of the Retek Dividend, HNC shall, in accordance with GAAP,
grant the holder thereof an additional option to purchase HNC Common Stock in
accordance with GAAP. Each such additional option shall be granted as soon as
administratively feasible following the date the Retek Dividend is paid to the
stockholders of HNC. HNC shall have no obligation to make any cash payments to
the holders of such HNC Options in connection with the Retek Dividend, or to
make loans to the holders of such HNC Options with respect to the exercise of
such HNC Options or permit the exercise of such options with promissory notes.

<PAGE>   50


            (c) HNC has no reason to believe that the proposed Retek Dividend
(if paid) will not meet the conditions for "no sale" treatment outlined in SEC
Staff Legal Bulletin No. 4 dated September 16, 1997 regarding spin-offs. If,
however, the SEC or Retek takes action to treat the Retek common stock
distributed in the Retek Dividend as "restricted securities" within the meaning
of Rule 144, then HNC will grant certain S-3 registration rights to the SLC
Stockholders with respect to the HNC Common Stock issued under Section 2.1.2(a)
during the time period promptly following such SEC or Retek action (taking into
account that it shall take HNC time to prepare a registration statement and have
it reviewed and declared effective by the SEC) and ending on the first
anniversary of the Effective Time, provided that: (i) the terms and conditions
of such registration rights shall be set forth in a registration rights
agreement (the "SLC REGISTRATION RIGHTS AGREEMENT") substantially identical to
the Registration Rights Agreement entered into between HNC and The Center for
Adaptive Systems Applications, Inc. on March 17, 2000, except that the SLC
Registration Rights Agreement shall provide for two trading windows of 30 days
each (rather then 3 trading windows); and (ii) only SLC Stockholders who execute
and deliver such SLC Registration Rights Agreement to HNC will be entitled to
any registration rights.

        6.7 Rule 144. During the 144 Period (as defined below) HNC will use good
faith efforts to satisfy the current public information requirements of
paragraph (c) of Rule 144, as such requirements are now in effect. The "144
Period" means that time period beginning on the Effective Time and ending on the
earlier to occur of: (a) the second (2nd) anniversary of the Effective Time, (b)
the first date after the Effective Time on which HNC is no longer required to
file reports with the SEC under the 1934 Act, or (c) the first date on which
shares of HNC Common Stock issued under Section 2.1.2 hereof by virtue of the
Merger can be traded under Rule 144 without compliance with the current public
information requirements of paragraph (c) of Rule 144.

        6.8 Information Statement. HNC will cooperate with SLC in preparing the
Information Statement to be provided to the SLC Stockholders prior to the SLC
Stockholders' Vote. HNC shall also provide to SLC copies of all filings made in
connection with the Merger that HNC makes pursuant to the 1933 Act and any other
applicable securities and Blue Sky laws of any jurisdiction.

        6.9 Closing of Merger. HNC will not refuse to effect the Merger if, on
or before the Closing Date, all the conditions precedent to HNC's obligations to
effect the Merger under Article 9 have been satisfied or waived by HNC and SLC
elects to consummate the Merger.

        6.10 Tax Issues. HNC and the Surviving Corporation shall give written
notice to the SLC Stockholders after closing of any audit, claim, action, suit,
investigation or other proceedings related to SLC's or the Surviving
Corporation's taxes for any time period occurring prior to the Effective Time
that could reasonably be expected to have the effect of materially decreasing
SLC's deductions or credits or materially increasing SLC's taxable income for
any taxable year or period prior to the Closing. The SLC Stockholders shall be
entitled, at their expense, to participate in any such proceedings. The
foregoing provisions of this Section 6.11 shall not apply,


                                       50
<PAGE>   51

however, with respect to any audit, claim, action, suit, investigation or other
proceedings with respect to or challenging the validity of SLC's status as an S
corporation for any period prior to the Effective Time.

                                    ARTICLE 7

Certificate of Merger will be filed with the Delaware Secretary of State on the
first business day after the Closing Date.

        7.2 Surrender and Exchange of Stock Certificates.

            7.2.1 Surrender by SLC Stockholders. At the Closing, each holder of

the holder's signature notarized or signature guaranteed, for cancellation as of
the Effective Time.

            7.2.2 Delivery by HNC. Promptly after the Effective Time, HNC or its
transfer agent will issue and pay to each SLC Stockholder who has tendered to
HNC SLC Certificates representing all of the shares of SLC Common Stock held by
such SLC Stockholder immediately prior to the Effective Time in accordance with
the foregoing provisions of Section 7.2.1:

                (i) a certificate for the number of shares of HNC Common Stock
that such holder is entitled to receive upon the conversion of such holder's
shares of SLC Common Stock pursuant to the provisions of clause (a) of Section
2.1.2 (less the number of such shares that are Escrow Shares, which shall be
withheld and placed in escrow pursuant to the provisions of Section 2.7 and the
Escrow Agreement); and

                (ii) a wire transfer (provided that HNC shall have received all
necessary wire transfer instructions, and if not, a check) for the amount of
cash that such holder is entitled to receive upon the conversion of such
holder's shares of SLC Common Stock pursuant to the provisions of clause (b) of
Section 2.1.2 plus the amount of cash in lieu of fractional shares in the amount
payable to such holder in accordance with Section 2.2(a) with respect to the
shares issued under clause (a) of Section 2.1.2.

            7.2.3 No issuance of certificates of HNC Common Stock or payments of
cash described in Section 7.2.2 and no dividends or distributions payable to
holders of record of HNC Common Stock after the Effective Time (including
without limitation the Retek Dividend), will be paid to the holder of any
unsurrendered SLC Certificate with respect to the shares of HNC Common Stock
into which the shares of SLC Common Stock represented by such SLC Certificate
have been converted in the Merger until the holder of such unsurrendered SLC
Certificate surrenders such SLC Certificate to HNC as provided above. Subject to
the effect, if any, of applicable escheat and other laws, following surrender of
any SLC Certificate, there will be delivered to the person entitled thereto,
without interest, the amount of any such dividends and distributions theretofore
paid with respect to HNC Common Stock so withheld as of any date subsequent to
the Effective Time and prior to such date of delivery (including without
limitation the Retek Dividend, if the Retek Dividend is paid prior to such date
of delivery).

            7.2.4 After the Effective Time there will be no further registration
of transfers on the stock transfer books of SLC or its transfer agent of any
shares of SLC capital stock that was outstanding immediately prior to the
Effective Time. If, after the Effective Time, SLC Certificates are presented for
any reason, they will be canceled and exchanged as provided in this Section 7.2.

            7.2.5 Until SLC Certificates representing shares of SLC Common Stock
outstanding immediately prior to the Effective Time are surrendered pursuant to
Section 7.2.1 above, such SLC Certificates will be deemed, for all purposes, to
evidence the right to receive the number of shares of HNC Common Stock and cash
into which such shares of SLC Common Stock will have been converted pursuant to
Article 2 and the Merger, subject to all the provisions of this Agreement,
including but not limited to the provisions of Section 2.7 regarding the escrow,
and the Escrow Agreement.

            (ix) in addition to the foregoing, in the event that HNC's audit of
SLC's financial statements for the fiscal year ended December 31, 1999 as
conducted by HNC's accountants, results in a reduction of $500,000 or more in
either SLC's (A) "net earnings" per SLC's audited Statement of Operations and
Retained Earnings for SLC's fiscal year ended December 31, 1999 (a copy of which
is included in Schedule 3.8 to the SLC Disclosure Letter) or (B) "stockholders'
equity" per its audited December 31, 1999 Balance Sheet (a copy of which is
included in Schedule 3.8 to the SLC Disclosure Letter), in either case as
required by GAAP, the term "Loss" for which HNC or any HNC Indemnified Person
may be indemnified under this Section 11.2 shall also include the fees and
expenses of HNC's accountants and auditors for auditing, reviewing and restating
SLC's fiscal 1999 financial statement(s) in an amount not to exceed $50,000
("AUDIT LOSS"); provided, that notwithstanding the foregoing, the provisions of
this subparagraph (ix) shall not be interpreted to restrict, limit or adversely
affect in any way any indemnification rights of HNC or any HNC Indemnified
Person as provided in this Article 11 or the Escrow Agreement.

        Without limitation, any and all fees (including without limitation
reasonable attorneys' fees, accountants' fees and tax preparers' fees) relating
to the investigation, defense, remedy, settlement or satisfaction of any Loss
shall be deemed to have been incurred with respect to, or to have arisen out of,
the inaccuracy, misrepresentation, breach, default or liability giving rise to
such Loss. For purposes of this Article 11, the amount of Loss incurred by any
HNC Indemnified Person will be reduced by the amount of any insurance proceeds
actually received by such HNC Indemnified Person on account of such Loss, but
"Loss" will include any reasonable costs or expenses incurred by such HNC
Indemnified Person to recover such insurance proceeds.

        Notwithstanding the foregoing provisions of clause (viii) above
regarding 3.12(c) Loss, HNC agrees that, following the Effective Time, HNC and
the Surviving Corporation shall promptly devote the time and services of
appropriate and available skilled employees of HNC and/or the Surviving
Corporation (and independent contractors as and to the extent deemed reasonably
necessary or appropriate by HNC in its sole discretion) to perform diligent
efforts to [*]; provided however that: (a) HNC and/or the Surviving Corporation
will not be obligated to incur more than [*] of Direct Personnel Costs (as
hereinafter defined) in providing the time and services of such employees or
contractors for the purpose(s) described above in this paragraph; (b) the first
[*] of such Direct Personnel Costs incurred by HNC and/or the Surviving
Corporation for such purposes shall not be recoverable by HNC or any other HNC
Indemnified Person as 3.12(c) Loss under this Article 11; and (c) all Direct
Personnel Costs incurred by HNC and/or the Surviving Corporation in providing
the time and services of such employees and other personnel for the purposes
described above in this paragraph in excess of the

first [*] of such Direct Personnel Costs shall be recoverable by the applicable
HNC Indemnified Person(s) as 3.12(c) Loss from the General Escrow pursuant to
the provisions of this Section 11.2(a). For purposes of this paragraph, "DIRECT
PERSONNEL COSTS" means (i) the cost of salary and benefits for the relevant
employees of HNC and/or the Surviving Corporation (prorated based on generally
accepted cost accounting principles to reflect the relative time spent by such
persons on the matters [*] described in this paragraph), plus (ii) the cost of
consulting or contractor fees and expense reimbursements paid to any independent
contractors or consultants by HNC and/or the Surviving Corporation to any
independent contractor or consultant on the matters [*] described in this
paragraph.

            (b) Procedure for Making Indemnification Claims. Except as provided
in Sections 11.2(c), 11.2(i) or 11.5, any claim for indemnification made by or
on behalf of any HNC Indemnified Person under this Section 11.2 must be raised
in a writing delivered to the Representative and the Escrow Agent as provided in
the Escrow Agreement by no later than the Escrow Release Date, but any such
claim for indemnification, if so raised prior to the Escrow Release Date, may
continue to be prosecuted and resolved after the Escrow Release Date in
accordance with the provisions of this Article 11 and the terms and conditions
of the Escrow Agreement.

            (c) Extraordinary Loss Definitions. As used herein, the term
"EXTRAORDINARY LOSS" means, collectively or individually, any:

                (i) Fraud Loss (as defined above);

                (ii) Title Loss (as defined above);

                (iii) any inaccuracy, misrepresentation, breach of, or default
in any Special Representation ("SPECIAL REPRESENTATION LOSS"); and/or

                (iv) Investment Letter Loss (as defined above).

            (d) Percentage Interest; Merger Consideration; Value. As used
herein, "PERCENTAGE INTEREST" shall mean an Escrow Stockholder's percentage
ownership interest in the outstanding capital stock of SLC as of 5:00 p.m.,
Eastern Daylight Time, on August 31, 2000. The "MERGER CONSIDERATION" means all
of the shares of HNC Common Stock and cash payable to all SLC Stockholders
pursuant to Section 2.1.2 and any shares of Retek Common Stock issued as a
dividend on such shares of HNC Common Stock in the Retek Dividend. The "VALUE OF
AN ESCROW STOCKHOLDER'S PERCENTAGE INTEREST IN THE MERGER CONSIDERATION" means
the dollar amount equal to the product obtained by multiplying (i) such Escrow
Stockholder's Percentage Interest by (ii) the sum of (x) the total amount of all
cash payable to all SLC Stockholders in the Merger pursuant to Section 2.1.2(b)
plus (y) the product obtained by multiplying the HNC Closing Price Per Share by
the total number of shares of HNC Common Stock issuable to the SLC Stockholders
in the Merger pursuant to Section 2.1.2.

            (e) Fraud Loss. Each SLC Stockholder shall be liable for all Fraud
Loss without limitation on such SLC Stockholder's liability to the extent that
such Fraud Loss resulted from the fraudulent conduct or willful misconduct of
such SLC Stockholder. With respect to all Fraud Loss not resulting from the
fraudulent conduct or willful misconduct of such SLC Stockholder, such SLC
Stockholder (but only if such SLC Stockholder is an Escrow Stockholder) shall be
jointly and severally liable with all Escrow Stockholders for all such Fraud
Loss, but only to the extent of an amount equal to the Value of such Escrow
Stockholder's Percentage Interest in the Merger Consideration (as defined in
Section 11.2(d) above).

            (f) Special Representation Loss. Each Escrow Stockholder shall
jointly and severally liable for all Special Representation Loss, but only to
the extent of the Value of such Escrow Stockholder's Percentage Interest in the
Merger Consideration (as defined in Section 11.2(d) above).

            (g) Title Loss. Each SLC Stockholder shall be liable for all Title
Loss without limitation on its liability to the extent that Title Loss arose or
resulted from such SLC Stockholder's failure to have good, valid and marketable
title to, or the right to vote, any issued and outstanding shares of SLC Common
Stock held (or asserted to have been held) by such SLC Stockholder immediately
prior to the Effective Time, free and clear of all liens, claims and
encumbrances. With respect to Title Loss not resulting from the failure of such
SLC Stockholder to have good, valid and marketable title to outstanding shares
of SLC Common Stock, such SLC Stockholder (but only if such SLC Stockholder is
an Escrow Stockholder) shall be jointly and severally liable with all other
Escrow Stockholders for all such Title Loss, but only to the extent of such
Escrow Stockholder's Percentage Interest in the General Escrow Property.

            (h) Investment Letter Loss. Each SLC Stockholder shall be liable for
all Investment Letter Loss without limitation on its liability to the extent
that such Investment Letter Loss arose or resulted from such SLC Stockholder's
breach of its Investment Representation Letter. With respect to Investment
Letter Loss not resulting from the breach by such SLC Stockholder of an
Investment Representation Letter, such SLC Stockholder (but only if such SLC
Stockholder is an Escrow Stockholder) shall be jointly and severally liable with
all other Escrow Stockholders for all such Investment Letter Loss, but only to
the extent of such Escrow Stockholder's Percentage Interest in the General
Escrow Property.

            (i) Claims for Extraordinary Loss. Notwithstanding anything herein
to the contrary: (a) any claim or claims for indemnification for any Special
Representation Loss, Investment Letter Loss, Title Loss or 3.12(c) Loss may be
brought by or on behalf of any HNC Indemnified Person at any time prior to the
second (2nd) anniversary of the Effective Time (or, if later, within 30 days of
the expiration of any applicable tax statute of limitation in respect to a
Special Representation Loss relating to Section 3.7 hereof), and (b) any claim
or claims for indemnification for any Fraud Loss may be brought by or on behalf
of any HNC Indemnified Person at any time prior to the fourth (4th) anniversary
of the Effective Time, in either case by giving notice of such



                                       61
<PAGE>   62


claim (i) in the case of claim for Special Representation Loss or Fraud Loss
resulting from the fraudulent conduct of SLC, to the Representative (or to all
SLC Stockholders if such claim is made following the Escrow Release Date) and
(ii) in the case of any claim for Fraud Loss resulting from the fraudulent
conduct or willful misconduct of an SLC Stockholder or for any Investment Letter
Loss, Title Loss or 3.12(c) Loss, to Representative and the SLC Stockholder or
SLC Stockholders whose alleged fraudulent conduct or willful misconduct or whose
alleged breach of an Investment Representation Letter or alleged failure to have
good, valid and marketable title to, or the right to vote, SLC Common Stock gave
rise to or resulted in such Fraud Loss, Investment Letter Loss, Title Loss or
3.12(c) Loss, as the case may be; (b) except as set forth in this Section 11.2,
an Escrow Stockholder's liability for any Extraordinary Loss shall not be
subject to the limitations on such Escrow Stockholder's liability set forth in
Section 11.4; and (c) the Basket and any other limitations on the
indemnification obligations or liabilities of the Escrow Stockholders set forth
in Section 11.4 shall not be applicable to any claim by any HNC Indemnified
Person for indemnification for any Extraordinary Loss. Claims for Extraordinary
Loss raised by HNC or any other HNC Indemnified Person prior to the Escrow
Release Date will be prosecuted under the Escrow Agreement, to the extent that
the amount of Escrow Shares, cash and/or other property remaining in the General
Escrow under the Escrow Agreement and available to satisfy such claim of
Extraordinary Loss have a value (determined as provide in Section 4.6(e) of the
Escrow Agreement) equal to or in excess of the entire amount of Extraordinary
Loss claimed in good faith by HNC or such HNC Indemnified Person. Claims for
Extraordinary Loss not required to be prosecuted under the Escrow Agreement
under the terms of the preceding sentence, or which cannot be fully satisfied
from the property in the General Escrow, and any claims of Extraordinary Loss
first raised after the Escrow Release Date, may be prosecuted by HNC, at its
election, pursuant to the arbitration process described in Section 4 of the
Escrow Agreement (except that HNC's remedy will not be restricted to the
recovery of cash and Escrow Shares in the General Escrow) or, at HNC's election,
before any court having jurisdiction of the parties.

        11.3 11.3 Loss; 11.3 Escrow. Any Loss suffered or incurred by any HNC
Indemnified Person with respect to and/or arising out of, any inaccuracy,
misrepresentation or breach of any of SLC's representations or warranties in
Section 11.3 regarding obligations for [*] arising prior to, on or after the
Effective Time, including without limitation [*] obligations arising out of any
transactions first occurring after the Effective Time and any payments made in
settlement or compromise of any claim, suit, or other demand for any such
payments (collectively, "11.3 LOSS") shall be payable solely from the 11.3
Escrow Property (as defined in the Escrow Agreement) and shall not be payable
from the General Escrow Property (as defined in the Escrow Agreement); provided,
however, that any Loss incurred by an HNC Indemnified Person [*] other than an
11.3 Loss ("11.3 OTHER LOSS") shall be payable from the General Escrow and the
General Escrow Property. 11.3 Loss shall include, without limitation, any
amounts paid or forfeited by an HNC Indemnified Person [*] in settlement or
compromise of [*] , which settlement or compromise may be entered into on terms
and conditions acceptable to HNC and/or the Surviving Corporation in its sole
discretion,

notwithstanding anything to the contrary in Section 2.5 of the Escrow Agreement.
If HNC and/or the Surviving Corporation shall enter into a settlement or
compromise [*] in a form acceptable to HNC, then pursuant to the Escrow
Agreement the HNC Indemnified Persons shall direct the Escrow Agent to release
any residue of the property remaining in the 11.3 Escrow after all claims for
11.3 Loss have been satisfied in full in accordance with the procedures for
Settled Claims set forth in the Escrow Agreement. The 11.3 Escrow shall not be
available to satisfy any claims by HNC Indemnified Persons for Loss other than
11.3 Loss.

        11.4 Limitation. In seeking indemnification for Loss under Section 11.2
prior to the Escrow Release Date, the HNC Indemnified Persons will exercise
their remedies first with respect to the Escrow Shares, cash and other property
deposited in the General Escrow pursuant to the Escrow Agreement (to the extent
the General Escrow is still available and in effect) and, to the extent that
such Escrow Shares, cash and other property are not sufficient to satisfy the
indemnity obligations hereunder, second against the SLC Stockholders directly
and personally. Except as provided in Sections 11.2 and 11.3: (a) no Escrow
Stockholder will have any liability to an HNC Indemnified Person except to the
extent of the Value of such Escrow Stockholder's Percentage Interest in the
Merger Consideration; and (b) the remedies set forth in this Section 11.4 and
the Escrow Agreement will be the exclusive remedies of HNC and the other HNC
Indemnified Persons under Section 11.2 of this Agreement against any SLC
Stockholder for indemnification obligations under Section 11.2(a). In addition,
the indemnification provided for in Section 11.2(a) shall not apply unless and
until the aggregate Damages for which one or more HNC Indemnified Persons seeks
or has sought indemnification hereunder exceeds a cumulative aggregate of One
Hundred Thousand Fifty Dollars ($150,000) (the "BASKET"), in which event the
Escrow Stockholders shall, subject to the foregoing limitations, be liable to
indemnify the HNC Indemnified Persons for all Loss (including the amount of the
Basket); provided, however, that the Basket and the foregoing provisions of this
sentence shall not apply to any indemnification claim for Loss for Excess
Transaction Expenses (as defined below), for any Extraordinary Loss, or for any
11.3 Loss. However, notwithstanding anything herein to the contrary, none of the
limitations on the indemnification obligations set forth in this Section 11.4
shall be applicable to any claim of indemnification for any Extraordinary Loss
as set forth in Section 11.2 or for any 11.3 Loss (except that recovery for 11.3
Loss shall be limited to the 11.3 Escrow Property). The Representative and HNC
may, by mutual written agreement prior to the Escrow Release Date, extend the
time during which an HNC Indemnified Person may make any claim or claims for
indemnification for any 11.3 Loss for up to an additional six (6) months, in
which case (i) the 11.3 Escrow shall remain in existence in accordance with the
Escrow Agreement during the term of such mutually agreed-on extension of the
11.3 Escrow and (ii) the representations and warranties in Section 11.3 shall
remain operative and in effect during the term of such mutually agreed-upon
extension (if any).

        11.5 Notice. Promptly after HNC becomes aware of the existence of any
potential claim by an HNC Indemnified Person for indemnity from SLC Stockholders
under Section 11.2, HNC will notify the Representative or relevant SLC
Stockholders, as

applicable as provided in Section 11.2(i), of such potential claim in accordance
with the Escrow Agreement. Failure of HNC to give such notice will not affect
any rights or remedies of any Indemnified Party hereunder with respect to
indemnification for Loss except to the extent that the SLC Stockholders are
materially prejudiced thereby.

                                   ARTICLE 12
                                  MISCELLANEOUS

        12.1 Governing Law. The internal laws of the State of Delaware
(irrespective of its choice of law principles) as applied to residents of the
State of Delaware will govern the validity of this Agreement, the construction
of its terms, and the interpretation and enforcement of the rights and duties of
the parties hereto.

        12.2 Assignment; Binding Upon Successors and Assigns. Neither party
hereto may assign any of its rights or obligations hereunder without the prior
written consent of the other party hereto. Subject to the foregoing, this
Agreement will be binding upon and inure to the benefit of the parties hereto
and their respective successors and permitted assigns.

        12.3 Severability. If any provision of this Agreement, or the
application thereof, will for any reason and to any extent be invalid or
unenforceable, then the remainder of this Agreement and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to give effect to the intent of the parties hereto. The parties further agree to
replace such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the maximum extent legally
permissible, the economic, business and other purposes of the void or
unenforceable provision.

        12.4 Counterparts. This Agreement may be executed in any number of
counterparts, each of which will be an original as regards any party whose
signature appears thereon and all of which together will constitute one and the
same instrument. This Agreement will become binding when one or more
counterparts hereof, individually or taken together, will bear the signatures of
all the parties reflected hereon as signatories and have been delivered by each
party to each other party (whether in facsimile or original form).

        12.5 Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby or by law on such party,
and the exercise of any one right or remedy will not preclude the exercise of
any other right or remedy.

        12.6 Amendment and Waivers. This Agreement may be amended by the parties
hereto at any time but only by a writing signed by HNC and SLC. Any such
amendment may be made at any time before or after approval of the SLC
Stockholders, but, after such approval, no amendment will be made which by
applicable law requires the further approval of the SLC Stockholders without
obtaining such further approval.


                                       64
<PAGE>   65

The observance of any term or provision of this Agreement may be waived (either
generally or in a particular instance and either retroactively or prospectively)
only by a writing signed by the party to be bound by such waiver. The waiver by
a party of any breach hereof or default in the performance hereof will not be
deemed to constitute a waiver of any other default or any succeeding breach or
default. At any time prior to the Effective Time, each of SLC and HNC, may, to
the extent legally allowed, (a) extend the time for the performance of any of
the obligations or other acts of the other; (b) waive any inaccuracies in the
representations and warranties made to it contained herein or in any document
delivered pursuant hereto; and (c) waive compliance with any of the agreements
or conditions for its benefit contained herein. No such waiver or extension will
be effective unless signed in writing by the party against whom such waiver or
extension is asserted. The failure of any party to enforce any of the provisions
hereof will not be construed to be a waiver of the right of such party
thereafter to enforce such provisions.

        12.7 Expenses. HNC and Sub will each bear their own legal fees,
accounting fees, brokers' fees investment banking, financial advisors' fees and
other expenses incurred with respect to this Agreement, and the transactions
contemplated hereby (the "TRANSACTION EXPENSES"); provided, however, that if the
Merger is successfully consummated, then up to a maximum of $100,000 of SLC's
verified Transaction Expenses will be paid by HNC, and HNC shall be entitled to
indemnification from the Escrow Shares in accordance with Section 11.2 for an
amount equal to the amount (if any) by which SLC's Transaction Expenses exceed
$100,000 (such excess being hereinafter called the "EXCESS TRANSACTION
EXPENSES"), and such indemnification shall not be subject to the Basket.

        12.8 Short S Year Tax Return. The SLC Stockholders shall at their sole
cost and expense prepare, or cause to be prepared, all tax returns that are
required to be filed with respect to SLC for pre-Closing tax periods; provided
that neither any SLC stockholder nor any tax preparer or other agent (acting on
behalf of any such SLC stockholder, or acting on behalf of SLC without HNC's
prior written authorization) shall sign or file any such tax return or returns
with the Internal Revenue Service or with any other taxing authority. Any such
tax return (together with all related schedules, statements and supporting
documentation) shall, prior to its filing, be submitted by the Representative to
HNC by no later than December 1, 2000 and HNC and its accountants shall have the
sole right and authority to sign and file any such tax return with the Internal
Revenue Service or any other applicable taxing authority or government
authority. HNC and its accountants shall, prior to the filing of any such tax
return, be entitled to make such corrections and changes to such tax return as
HNC determines are required in order to correctly complete such tax return in
compliance with applicable law. HNC and its accountants shall have the right to
review all work papers and procedures used by the SLC stockholders, their tax
preparer or their accountant to prepare any such tax return.

        12.9 Attorneys' Fees. Should suit be brought to enforce or interpret any
part of this Agreement, the prevailing party will be entitled to recover, as an
element of the costs of suit and not as damages, reasonable attorneys' fees to
be fixed by the court (including

without limitation, costs, expenses and fees on any appeal). The prevailing
party will be entitled to recover its costs of suit, regardless of whether such
suit proceeds to final judgment.

        12.11 Construction of Agreement. This Agreement has been negotiated by
the respective parties hereto and their attorneys and the language hereof will
not be construed for or against either party. A reference to a Section or an
exhibit will mean a Section in, or exhibit to, this Agreement unless otherwise
explicitly set forth. The titles and headings herein are for reference purposes
only and will not in any manner limit the construction of this Agreement which
will be considered as a whole.

        12.12 No Joint Venture. Nothing contained in this Agreement will be
deemed or construed as creating a joint venture or partnership between any of
the parties hereto. No party is by virtue of this Agreement authorized as an
agent, employee or legal representative of any other party. No party will have
the power to control the activities and operations of any other and their status
is, and at all times will continue to be, that of independent contractors with
respect to each other. No party will have any power or authority to bind or
commit any other. No party will hold itself out as having any authority or
relationship in contravention of this Section.

        12.13 Further Assurances. Each party agrees to cooperate fully with the
other parties and to execute such further instruments, documents and agreements
and to give such further written assurances as may be reasonably requested by
any other party to evidence and reflect the transactions described herein and
contemplated hereby and to carry into effect the intents and purposes of this
Agreement.

        12.14 Absence of Third Party Beneficiary Rights. No provisions of this
Agreement are intended, nor will be interpreted, to provide or create any third
party beneficiary rights or any other rights of any kind in any client,
customer, affiliate,


                                       67
<PAGE>   68

stockholder, or partner of any party hereto or any other person or entity unless
specifically provided otherwise herein, and, except as so provided, all
provisions hereof will be personal solely between the parties to this Agreement.

        12.15 Public Announcement. Upon execution of this Agreement, HNC and SLC
will issue a press release approved by both parties announcing the Merger.
Thereafter, HNC may issue such press releases, and make such other disclosures
regarding the Merger, as it determines are required under applicable securities
laws or regulatory rules. HNC will submit all such press releases and other
disclosures to be issued prior to the Effective Time to SLC for SLC's review and
approval before HNC releases or files them and SLC agrees not to unreasonably
withhold, delay or condition its approval of any such press release or
disclosure. Prior to the publication of such press release (unless this
Agreement has been terminated), neither party will make any public announcement
relating to this Agreement or the transactions contemplated hereby and SLC will
use its reasonable efforts to prevent any trading in HNC Common Stock by its
officers, directors, employees, stockholders and agents.

        12.16 Confidentiality. SLC and HNC recognize that they have received
confidential information concerning the others during the course of the Merger
negotiations and preparations. Accordingly, each of the parties hereto (a)
represents that it has not permitted the unauthorized disclosure of any
confidential information concerning the other parties hereto that was disclosed
during the course of such negotiations and preparations and was clearly
designated in writing as confidential at the time of disclosure and (b) agrees
to not make use of or permit to be used any such confidential information other
than for the purpose of effectuating the Merger and related transactions. The
obligations of HNC under this Section will terminate upon the Effective Time;
otherwise, the obligations of both parties under this Section 12.16 shall
survive the termination of this Agreement without Closing. The obligations of
the parties under this Section 12.16 will not apply to information that (i) is
or becomes part of the public domain other than through the actions (directly or
indirectly) of the receiving party, (ii) is disclosed by the disclosing party to
third parties without restrictions on disclosure, (iii) is received by the
receiving party from a third party without breach of a nondisclosure obligation
to the other party, (iv) is required to be disclosed by HNC under state and
federal securities laws, or (v) is required to be disclosed by subpoena or by
law (other than securities laws), in which case the receiving party will give
prompt notice to the disclosing party prior to such required disclosure so that
the disclosing party may seek an appropriate protective order. If this Agreement
is terminated, all copies of documents containing confidential information shall
be returned by the receiving party to the disclosing party.

        12.17 Entire Agreement. This Agreement and the exhibits and schedules
hereto and the SLC Disclosure Letter and HNC Disclosure Letter constitute the
entire understanding and agreement of the parties hereto with respect to the
subject matter hereof and supersede all prior and contemporaneous agreements or
understandings, inducements or conditions, express or implied, written or oral,
between the parties with respect hereto other than the Confidentiality
Agreement. The express terms hereof


                                       68

control and supersede any course of performance or usage of the trade
inconsistent with any of the terms hereof.
