Item 1.  DESCRIPTION OF SECURITIES TO BE REGISTERED

         On January 9, 1997, pursuant to a Preferred Shares Rights Agreement 
(the "Rights Agreement") between Loronix Information Systems, Inc. (the 
"Company") and American Stock Transfer & Trust Company, as Rights Agent (the 
"Rights Agent"), the Company's Board of Directors declared a dividend of one 
right (a "Right") to purchase one one-thousandth share of the Company's 
Series A Participating Preferred Stock (the "Series A Preferred") for each 
outstanding share of Common Stock, $.001 par value (the "Common Shares"), of 
the Company.  The dividend is payable on March 14, 1997 (the "Record 
Date") to stockholders of record as of the close of business on that date.  
Each Right entitles the registered holder to purchase from the Company one 
one-thousandth of a share of Series A Preferred at an exercise price of 
$22.00 (the "Purchase Price"), subject to adjustment.

    The following summary of the principal terms of the Rights Agreement is a 
general description only and is subject to the detailed terms and conditions 
of the Rights Agreement.  A copy of the Rights Agreement is attached as 
Exhibit 1 to this Registration Statement and is incorporated herein by 
reference.

RIGHTS EVIDENCED BY COMMON SHARE CERTIFICATES

    The Rights will not be exercisable until the Distribution Date (defined 
below).  Certificates for the Rights ("Rights Certificates") will not be sent 
to stockholders and the Rights will attach to and trade only together with 
the Common Shares.  Accordingly, Common Share certificates outstanding on the 
Record Date will evidence the Rights related thereto, and Common Share 
certificates issued after the Record Date will contain a notation 
incorporating the Rights Agreement by reference.  Until the Distribution Date 
(or earlier redemption or expiration of the Rights), the surrender or 
transfer of any certificates for Common Shares, outstanding as of the Record 
Date, even without notation or a copy of the summary of rights (attached as 
Exhibit C to the Rights Agreement) being attached thereto, will also 
constitute the transfer of the Rights associated with the Common Shares 
represented by such certificate.

DISTRIBUTION DATE

    The Rights will separate from the Common Shares, Rights Certificates will 
be issued and the Rights will become exercisable upon the earlier of:  (i) 
the close of business on the tenth day (or such later date as may be 
determined by a majority of the Board of Directors, excluding directors 
affiliated with the Acquiring Person, as defined below (the "Continuing 
Directors")) following a public announcement that a person or group of 
affiliated or associated persons (an "Acquiring Person") has acquired, or 
obtained the right to acquire, beneficial ownership of 15% or more of the 
outstanding Common Shares, or (ii) the close of business on the tenth 
business day (or such later date as may be determined by a majority of the 
Continuing Directors) following the commencement of, or announcement of an 
intention to make, a tender offer or exchange offer the consummation of which 
would result in the beneficial ownership by a person or group of 15% or more 
of the outstanding Common Shares.  The earlier of such dates is referred to 
as the "Distribution Date."

                                     -2-

<PAGE>

ISSUANCE OF RIGHTS CERTIFICATES; EXPIRATION OF RIGHTS

    As soon as practicable following the Distribution Date, separate Rights 
Certificates will be mailed to holders of record of the Common Shares as of 
the close of business on the Distribution Date and such separate Rights 
Certificates alone will evidence the Rights from and after the Distribution 
Date.  All Common Shares issued prior to the Distribu-tion Date will be 
issued with Rights.  Common Shares issued after the Distribution Date may be 
issued with Rights if such shares are issued (i) upon the conversion of 
outstanding convertible debentures or any other convertible securities issued 
after adoption of the Rights Agreement or (ii) pursuant to the exercise of 
stock options or under employee benefit plans or arrangements unless such 
issuance would result in (or create a risk that) such options, plans or 
arrangements would not qualify for otherwise available special tax treatment. 
Except as otherwise determined by the Board of Directors, no other Common 
Shares issued after the Distribution Date will be issued with Rights.  The 
Rights will expire on the earliest of (i) the close of business on March 14, 
2007 (the "Final Expiration Date"), (ii) redemption or exchange of the Rights 
as described below, or (iii) consummation of an acquisition of the Company 
satisfying certain conditions by a person who acquired shares pursuant to a 
Permitted Offer as described below.

INITIAL EXERCISE OF THE RIGHTS

    Following the Distribution Date, and until one of the further events 
described below, holders of the Rights will be entitled to receive, upon 
exercise and the payment of $22.00 per Right, one one-thousandth share of 
the Series A Preferred.  In the event that the Company does not have 
sufficient Series A Preferred available for all Rights to be exercised, or 
the Board of Directors decides that such action is necessary and not contrary 
to the interests of Rights holders, the Company may instead substitute cash, 
assets or other securities for the Series A Preferred for which the Rights 
would have been exercisable under this provision or as described below.

RIGHT TO BUY COMPANY COMMON SHARES

    Unless the Rights are earlier redeemed, in the event that an Acquiring 
Person becomes the beneficial owner of 15% or more of the Company's Common 
Shares then outstanding (other than pursuant to a Permitted Offer), then 
proper provision will be made so that each holder of a Right which has not 
theretofore been exercised (other than Rights beneficially owned by the 
Acquiring Person, which will thereafter be void) will thereafter have the 
right to receive, upon exercise, Common Shares having a value equal to two 
times the Purchase Price.  Rights are not exercisable following the 
occurrence of an event as described above until such time as the Rights are 
no longer redeemable by the Company as set forth below.

                                     -3-

<PAGE>

RIGHT TO BUY ACQUIRING COMPANY STOCK

    Similarly, unless the Rights are earlier redeemed, in the event that, 
after the Shares Acquisition Date (as defined below), (i) the Company is 
acquired in a merger or other business combination transaction, or (ii) 50% 
or more of the Company's consolidated assets or earning power are sold (other 
than in transactions in the ordinary course of business), proper provision 
must be made so that each holder of a Right which has not theretofore been 
exercised (other than Rights beneficially owned by the Acquiring Person, 
which will thereafter be void) will thereafter have the right to receive, 
upon exercise, shares of common stock of the acquiring company having a value 
equal to two times the Purchase Price (unless the transaction satisfies 
certain conditions and is consummated with a person who acquired shares 
pursuant to a Permitted Offer, in which case the Rights will expire).

PERMITTED OFFER

    A Permitted Offer means a tender offer for all outstanding Common Shares 
that has been determined by a majority of the Continuing Directors to be 
adequate and otherwise in the best interests of the Company and its 
stockholders.  Where the Board of Directors has determined that a tender 
offer constitutes a Permitted Offer, the Rights will not become exercisable 
to purchase Common Shares or shares of the acquiring company (as the case may 
be) at the discounted price described above.

EXCHANGE PROVISION

    At any time after the acquisition by an Acquiring Person of 15% or more 
of the Company's outstanding Common Shares and prior to the acquisition by 
such Acquiring Person of 50% or more of the Company's outstanding Common 
Shares, the Board of Directors of the Company may exchange the Rights (other 
than Rights owned by the Acquiring Person), in whole or in part, at an 
exchange ratio of one Common Share per Right.

REDEMPTION

    At any time on or prior to the close of business on the earlier of (i) 
the 10th day following the acquisition by an Acquiring Person (the "Share 
Acquisition Date") or such later date as may be determined by a majority of 
the Continuing Directors and publicly announced by the Company, or (ii) the 
Final Expiration Date of the Rights, the Company may redeem the Rights in 
whole, but not in part, at a price of $.01 per Right.

ADJUSTMENTS TO PREVENT DILUTION

    The Purchase Price payable, the number of Rights, and the number of 
Series A Preferred or Common Shares or other securities or property issuable 
upon exercise of the Rights are subject to adjustment from time to time in 
connection with the dilutive issuances by the Company as set forth in the 
Rights Agreement.  With certain exceptions, no adjustment in the Purchase 
Price will be required until cumulative adjustments require an adjustment of 
at least 1% in such Purchase Price. 

                                     -4-

<PAGE>

CASH PAID INSTEAD OF ISSUING FRACTIONAL SHARES

    No fractional portion less than integral multiples of one Common Share 
will be issued upon exercise of a Right and in lieu thereof, an adjustment in 
cash will be made based on the market price of the Common Shares on the last 
trading date prior to the date of exercise. 

NO STOCKHOLDERS' RIGHTS PRIOR TO EXERCISE

    Until a Right is exercised, the holder thereof, as such, will have no 
rights as a stockholder of the Company (other than any rights resulting from 
such holder's ownership of Common Shares), including, without limitation, the 
right to vote or to receive dividends.

AMENDMENT OF RIGHTS AGREEMENT

    The provisions of the Rights Agreement may be supplemented or amended by 
the Board of Directors in any manner prior to the close of business on the 
Distribution Date without the approval of Rights holders.  After the 
Distribution Date, the provisions of the Rights Agreement may be amended by 
the Board of Directors in order to cure any ambiguity, defect or 
inconsistency, to make changes which do not adversely affect the interests of 
holders of Rights (excluding the interests of any Acquiring Person), or to 
shorten or lengthen any time period under the Rights Agreement; provided, 
however, that no amendment to adjust (i) the time period governing redemption 
shall be made at such time as the Rights are not redeemable, or (ii) any 
other time period unless such lengthening is for the purpose of protecting, 
enhancing or clarifying the rights of and/or benefits to the holders of the 
Rights.

RIGHTS AND PREFERENCES OF THE SERIES A PREFERRED

    Series A Preferred purchasable upon exercise of the Rights will not be 
redeemable.  Each share of Series A Preferred will be entitled to an 
aggregate dividend of 1,000 times the dividend declared per Common Share.  In 
the event of liquidation, the holders of the Series A Preferred will be 
entitled to a minimum preferential liquidation payment equal to 1,000 times 
the per share amount to be distributed to the holders of the Common Shares.  
Each share of Series A Preferred will have 1,000 votes, voting together with 
the Common Shares.  In the event of any merger, consolidation or other 
transaction in which the Common Shares are changed or exchanged, each share 
of Series A Preferred will be entitled to receive 1,000 times the amount 
received per Common Share.  These rights are protected by customary 
anti-dilution provisions.

    Because of the nature of the dividend, liquidation and voting rights of 
the shares of Series A Preferred, the value of the one one-thousandth 
interest in a share of Series A Preferred purchasable upon exercise of each 
Right should approximate the value of one Common Share.

                                     -5-

CERTAIN ANTI-TAKEOVER EFFECTS

    The Rights approved by the Board of Directors are designed to protect and 
maximize the value of the outstanding equity interests in the Company in the 
event of an unsolicited attempt by an acquiror to take over the Company, in a 
manner or on terms not approved by the Board of Directors.  Takeover attempts 
frequently include coercive tactics to deprive the Company's Board of 
Directors and its stockholders of any real opportunity to determine the 
destiny of the Company.  The Rights have been declared by the Board of 
Directors in order to deter such tactics, including a gradual accumulation of 
shares in the open market of a 15% or greater position to be followed by a 
merger or a partial or two-tier tender offer that does not treat all 
stockholders equally.  These tactics unfairly pressure stockholders, squeeze 
them out of their investment without giving them any real choice and deprive 
them of the full value of their shares.

    The Rights are not intended to prevent a takeover of the Company and will 
not do so.  The Rights may be redeemed by the Company at $.01 per Right 
within ten days (or such later date as may be determined by a majority of the 
Board of Directors, excluding directors affiliated with an Acquiring Person) 
after the accumulation of 15% or more of the Company's shares by a single 
acquiror or group.  Accordingly, the Rights should not interfere with any 
merger or business combination approved by the Board of Directors.

    Issuance of the Rights does not in any way weaken the financial strength 
of the Company or interfere with its business plans.  The issuance of the 
Rights themselves has no dilutive effect, will not affect reported earnings 
per share, should not be taxable to the Company or to its stockholders, and 
will not change the way in which the Company's shares are presently traded.  
The Company's Board of Directors believes that the Rights represent a sound 
and reasonable means of addressing the complex issues of corporate policy 
created by the current takeover environment.

     However, the Rights may have the effect of rendering more difficult or 
discouraging an acquisition of the Company deemed undesirable by the Board of 
Directors.  The Rights may cause substantial dilution to a person or group 
that attempts to acquire the Company on terms or in a manner not approved by 
the Company's Board of Directors, except pursuant to an offer conditioned 
upon the negation, purchase or redemption of the Rights.

     Agreement, dated as of January 9, 1997, between Loronix Information 
Systems, Inc., a Nevada corporation ("THE COMPANY"), and American Stock 
Transfer & Trust Company (the "RIGHTS AGENT").

     On January 9, 1997, (the "RIGHTS DIVIDEND DECLARATION DATE"), the Board 
of Directors of the Company authorized and declared a dividend of one 
Preferred Share Purchase Right (a "Right") for each Common Share (as 
hereinafter defined) of the Company outstanding as of the Close of Business 
(as hereinafter defined) on March 14, 1997, (the "Record Date"), each 
Right representing the right to purchase one one-thousandth of a share of 
Series A Participating Preferred Stock (as such number may be adjusted 
pursuant to the provisions of this Agreement), having the rights, preferences 
and privileges set forth in the form of Certificate of Designations of 
Rights, Preferences and Privileges of Series A Participating Preferred Stock 
attached hereto as Exhibit A, upon the terms and subject to the conditions 
herein set forth, and further authorized and directed the issuance of one 
Right (as such number may be adjusted pursuant to the provisions of this 
Agreement) with respect to each Common Share that shall become outstanding 
between the Record Date and the earlier of the Distribution Date and the 
Expiration Date (as such terms are hereinafter defined), and in certain 
circumstances after the Distribution Date.

     NOW, THEREFORE, in consideration of the promises and the mutual 
agreements herein set forth, the parties hereby agree as follows:

     Section 1.     CERTAIN DEFINITIONS.  For purposes of this Agreement, the 
following terms have the meanings indicated:

          (a)  "Acquiring Person" shall mean any Person who or which, 
together with all Affiliates and Associates of such Person, shall be the 
Beneficial Owner of 15% or more of the Common Shares then outstanding, but 
shall not include the Company, any Subsidiary of the Company or any employee 
benefit plan of the Company or of any Subsidiary of the Company, or any 
entity holding Common Shares for or pursuant to the terms of any such plan, 
or Edward Jankowsky (together with his Affiliates and Associates).  
Notwithstanding the foregoing, no Person shall be deemed to be an Acquiring 
Person as the result of an acquisition of Common Shares by the Company which, 
by reducing the number of shares outstanding, increases the proportionate 
number of shares beneficially owned by such Person to 15% or more of the 
Common Shares of the Company then outstanding; provided, however, that if a 
Person shall become the Beneficial Owner of 15% or more of the Common Shares 
of the Company then outstanding by reason of share purchases by the Company 
and shall, after such share purchases by the Company, become the Beneficial 
Owner of any additional Common Shares of the Company (other than pursuant to 
a dividend or distribution paid or made by the Company on the outstanding 
Common Shares in Common Shares or pursuant to a split or subdivision of the 
outstanding Common Shares), then such Person shall be deemed to be an 
Acquiring Person unless upon becoming the Beneficial Owner of such additional 
Common Shares of the Company such Person does not beneficially own 15% or 
more of the Common Shares of the Company then outstanding. Notwithstanding 
the foregoing, (i) if a majority of the Continuing Directors then in office 
determines in good faith that a Person who would otherwise be an "Acquiring 
Person," as defined pursuant to the foregoing provisions of this paragraph 
(a), has become such inadvertently (including, without limitation, because 
(A) such Person was unaware that it beneficially 

<PAGE>

owned a percentage of the Common Shares that would otherwise cause such 
Person to be an "Acquiring Person," as defined pursuant to the foregoing 
provisions of this paragraph (a), or (B) such Person was aware of the extent 
of the Common Shares it beneficially owned but had no actual knowledge of the 
consequences of such beneficial ownership under this Agreement) and without 
any intention of changing or influencing control of the Company, and if such 
Person divested or divests as promptly as practicable a sufficient number of 
Common Shares so that such Person would no longer be an "Acquiring Person," 
as defined pursuant to the foregoing provisions of this paragraph (a), then 
such Person shall not be deemed to be or to have become an "Acquiring Person" 
for any purposes of this Agreement; and (ii) if, as of the date hereof, any 
Person is the Beneficial Owner of 15% or more of the Common Shares 
outstanding, such Person shall not be or become an "Acquiring Person," as 
defined pursuant to the foregoing provisions of this paragraph (a), unless 
and until such time as such Person shall become the Beneficial Owner of 
additional Common Shares (other than pursuant to a dividend or distribution 
paid or made by the Company on the outstanding Common Shares in Common Shares 
or pursuant to a split or subdivision of the outstanding Common Shares), 
unless, upon becoming the Beneficial Owner of such additional Common Shares, 
such Person is not then the Beneficial Owner of 15% or more of the Common 
Shares then outstanding.

          (b)  "Adjustment Fraction" shall have the meaning set forth in
Section 11(a)(i) hereof.

          (c)  "Affiliate" and "Associate" shall have the respective meanings 
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations 
under the Exchange Act, as in effect on the date of this Agreement.

          (d)  A Person shall be deemed the "Beneficial Owner" of and shall 
be deemed to "Beneficially Own" any securities:

                    (i)  which such Person or any of such Person's Affiliates 
or Associates beneficially owns, directly or indirectly, for purposes of 
Section 13(d) of the Exchange Act and Rule 13d-3 thereunder (or any 
comparable or successor law or regulation);

                    (ii) which such Person or any of such Person's Affiliates 
or Associates has (A) the right to acquire (whether such right is exercisable 
immediately or only after the passage of time) pursuant to any agreement, 
arrangement or understanding (other than customary agreements with and 
between underwriters and selling group members with respect to a bona fide 
public offering of securities), or upon the exercise of conversion rights, 
exchange rights, rights (other than the Rights), warrants or options, or 
otherwise; provided, however, that a Person shall not be deemed pursuant to 
this Section 1(d)(ii)(A) to be the Beneficial Owner of, or to beneficially 
own, (1) securities tendered pursuant to a tender or exchange offer made by 
or on behalf of such Person or any of such Person's Affiliates or Associates 
until such tendered securities are accepted for purchase or exchange, or (2) 
securities which a Person or any of such Person's Affiliates or Associates 
may be deemed to have the right to acquire pursuant to any merger or other 
acquisition agreement between the Company and such Person (or one or more of 
its Affiliates or Associates) if such agreement has been approved by the 
Board of Directors of the Company prior to there being an Acquiring Person; 
or (B) the right to vote pursuant to any agreement, arrangement or 
understanding; provided, however, that a Person shall not be deemed the 

                                       -2-
<PAGE>

Beneficial Owner of, or to beneficially own, any security under this Section 
1(d)(ii)(B) if the agreement, arrangement or understanding to vote such 
security (1) arises solely from a revocable proxy or consent given to such 
Person in response to a public proxy or consent solicitation made pursuant 
to, and in accordance with, the applicable rules and regulations of the 
Exchange Act and (2) is not also then reportable on Schedule 13D under the 
Exchange Act (or any comparable or successor report); or

                    (iii)     which are beneficially owned, directly or 
indirectly, by any other Person (or any Affiliate or Associate thereof) with 
which such Person or any of such Person's Affiliates or Associates has any 
agreement, arrangement or understanding, whether or not in writing (other 
than customary agreements with and between underwriters and selling group 
members with respect to a bona fide public offering of securities) for the 
purpose of acquiring, holding, voting (except to the extent contemplated by 
the proviso to Section 1(d)(ii)(B)) or disposing of any securities of the 
Company; provided, however, that in no case shall an officer or director of 
the Company be deemed (x) the Beneficial Owner of any securities beneficially 
owned by another officer or director of the Company solely by reason of 
actions undertaken by such persons in their capacity as officers or directors 
of the Company or (y) the Beneficial Owner of securities held of record by 
the trustee of any employee benefit plan of the Company or any Subsidiary of 
the Company for the benefit of any employee of the Company or any Subsidiary 
of the Company, other than the officer or director, by reason of any 
influence that such officer or director may have over the voting of the 
securities held in the plan.

Business Day it shall mean 5:00 P.M., Denver Time, on the next succeeding 
Business Day.

          (g)  "Common Shares" when used with reference to the Company shall 
mean the shares of Common Stock of the Company, $.001 par value.  Common 
Shares when used with reference to any Person other than the Company shall 
mean the capital stock (or equity interest) with the greatest voting power of 
such other Person or, if such other Person is a Subsidiary of another Person, 
the Person or Persons which ultimately control such first-mentioned Person.

          (j)  "Continuing Director" shall mean (i) any member of the Board 
of Directors of the Company who, while a member of the Board, is not an 
Acquiring Person, or an Affiliate or Associate of an Acquiring Person, or a 
representative of an Acquiring Person or of any such Affiliate or Associate, 
and who was a member of the Board prior to there being an Acquiring Person, 
and (ii) any Person who subsequently becomes a member of the Board and who, 
while a member of the Board, is not an Acquiring 

                                       -3-
<PAGE>

Person, or an Affiliate or Associate of an Acquiring Person, or a 
representative of an Acquiring Person or of any such Affiliate or Associate, 
if such Person's nomination for election or election to the Board is 
recommended or approved by a majority of the Continuing Directors.

          (k)  "Current Per Share Market Price" of any security (a "Security" 
for purposes of this definition), for all computations other than those made 
pursuant to Section 11(a)(iii) hereof, shall mean the average of the daily 
closing prices per share of such Security for the thirty (30) consecutive 
Trading Days immediately prior to such date, and for purposes of computations 
made pursuant to Section 11(a)(iii) hereof, the Current Per Share Market 
Price of any Security on any date shall be deemed to be the average of the 
daily closing prices per share of such Security for the ten (10) consecutive 
Trading Days immediately prior to such date; provided, however, that in the 
event that the Current Per Share Market Price of the Security is determined 
during a period following the announcement by the issuer of such Security of 
(i) a dividend or distribution on such Security payable in shares of such 
Security or securities convertible into such shares or (ii) any subdivision, 
combination or reclassification of such Security, and prior to the expiration 
of the applicable thirty (30) Trading Day or ten (10) Trading Day period, 
after the ex-dividend date for such dividend or distribution, or the record 
date for such subdivision, combination or reclassification, then, and in each 
such case, the Current Per Share Market Price shall be appropriately adjusted 
to reflect the current market price per share equivalent of such Security.  
The closing price for each day shall be the last sale price, regular way, or, 
in case no such sale takes place on such day, the average of the closing bid 
and asked prices, regular way, in either case as reported in the principal 
consolidated transaction reporting system with respect to securities listed 
or admitted to trading on the New York Stock Exchange or, if the Security is 
not listed or admitted to trading on the New York Stock Exchange, as reported 
in the principal consolidated transaction reporting system with respect to 
securities listed on the principal national securities exchange on which the 
Security is listed or admitted to trading or, if the Security is not listed

bid and low asked prices in the over-the-counter market, as reported by 
Nasdaq or such other system then in use, or, if on any such date the Security 
is not quoted by any such organization, the average of the closing bid and 
asked prices as furnished by a professional market maker making a market in 
the Security selected by the Board of Directors of the Company.  If on any 
such date no market maker is making a market in the Security, the fair value 
of such shares on such date as determined in good faith by the Board of 
Directors of the Company shall be used.  If the Preferred Shares are not 
publicly traded, the Current Per Share Market Price of the Preferred Shares 
shall be conclusively deemed to be the Current Per Share Market Price of the 
Common Shares as determined pursuant to this Section 1(k), as appropriately 
adjusted to reflect any stock split, stock dividend or similar transaction 
occurring after the date hereof, multiplied by 1000.  If the Security is not 
publicly held or so listed or traded, Current Per Share Market Price shall 
mean the fair value per share as determined in good faith by the Board of 
Directors of the Company, whose determination shall be described in a 
statement filed with the Rights Agent and shall be conclusive for all 
purposes.

for or pursuant to the terms of any such plan) is first published or sent or 
given within the meaning of Rule 14d-2(a) of the General Rules and

such appointment.  The Company may from time to time appoint such co-Rights

     Section 3.     ISSUANCE OF RIGHTS CERTIFICATES.

          (a)  Until the Distribution Date, (i) the Rights will be evidenced 
(subject to the provisions of Sections 3(b) and 3(c) hereof) by the 
certificates for Common Shares registered in the names of the holders thereof 
(which certificates shall also be deemed to be Rights Certificates) and not 
by separate Rights Certificates and (ii) the right to receive Rights 
Certificates will be transferable only in connection with the transfer of 
Common Shares.  Until the earlier of the Distribution Date or the Expiration 
Date, the surrender for transfer of certificates for Common Shares shall also 
constitute the surrender for transfer of the Rights associated with the 
Common Shares represented thereby.  As soon as practicable after the 
Distribution Date, the Company will prepare and execute, the Rights Agent 
will countersign, and the Company will send or cause to be sent (and the 
Rights Agent will, if requested, send) by first-class, postage-prepaid mail, 
to each record holder of Common Shares as of the Close of Business on the 
Distribution Date, at the address of such holder shown on the records of the 
Company, a Rights Certificate evidencing one Right for each Common Share so 
held, subject to adjustment as provided herein.  In the event that an 
adjustment in the number of Rights per Common Share has been made pursuant to 
Section 11 hereof, then at the time of distribution of the Rights 
Certificates, the Company shall make the necessary and appropriate rounding 
adjustments (in accordance with Section 14(a) hereof) so that Rights 
Certificates representing only whole numbers of Rights are distributed and 
cash is paid in lieu of any fractional Rights.  As of the Distribution Date, 
the Rights will be evidenced solely by such Rights Certificates and may be 
transferred by the transfer of the Rights Certificates as permitted hereby, 
separately and apart from any transfer of Common Shares, and the holders of 
such Rights Certificates as listed in the records of the Company or any 
transfer agent or registrar for the Rights shall be the record holders 
thereof.

                                       -7-
<PAGE>

          (b)  On the Record Date or as soon as practicable thereafter, the 
Company will send a copy of the Summary of Rights by first-class, 
postage-prepaid mail, to each record holder of Common Shares as of the Close 
of Business on the Record Date, at the address of such holder shown on the 
records of the Company's transfer agent and registrar.  With respect to 
certificates for Common Shares outstanding as of the Record Date, until the 
Distribution Date, the Rights will be evidenced by such certificates 
registered in the names of the holders thereof together with the Summary of 
Rights. Until the Distribution Date (or, if earlier, the Expiration Date), 
the surrender for transfer of any certificate for Common Shares outstanding 
on the Record Date, with or without a copy of the Summary of Rights, shall 
also constitute the transfer of the Rights associated with the Common Shares 
represented thereby.

          (c)  Unless the Board of Directors by resolution adopted at or 
before the time of the issuance of any Common Shares specifies to the 
contrary, Rights shall be issued in respect of all Common Shares that are 
issued after the Record Date but prior to the earlier of the Distribution 
Date or the Expiration Date or, in certain circumstances provided in Section 
22 hereof, after the Distribution Date.  Certificates representing such 
Common Shares shall also be deemed to be certificates for Rights, and shall 
bear the following legend:

     THIS CERTIFICATE ALSO EVIDENCES AND ENTITLES THE HOLDER HEREOF TO 
     CERTAIN RIGHTS AS SET FORTH IN A RIGHTS AGREEMENT BETWEEN LORONIX 
     INFORMATION SYSTEMS, INC. AND AMERICAN STOCK TRANSFER & TRUST 
     COMPANY, AS THE RIGHTS AGENT, DATED AS OF JANUARY 9, 1997, (THE 
     "RIGHTS AGREEMENT"), THE TERMS OF WHICH ARE HEREBY INCORPORATED 
     HEREIN BY REFERENCE AND A COPY OF WHICH IS ON FILE AT THE PRINCIPAL 
     EXECUTIVE OFFICES OF LORONIX INFORMATION SYSTEMS, INC.  UNDER 
     CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT, SUCH 
     RIGHTS WILL BE EVIDENCED BY SEPARATE CERTIFICATES AND WILL NO 
     LONGER BE EVIDENCED BY THIS CERTIFICATE.  LORONIX INFORMATION 
     SYSTEMS, INC. WILL MAIL TO THE HOLDER OF THIS CERTIFICATE A COPY OF 
     THE RIGHTS AGREEMENT WITHOUT CHARGE AFTER RECEIPT OF A WRITTEN 
     REQUEST THEREFOR.  UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE 
     RIGHTS AGREEMENT, RIGHTS ISSUED TO, OR HELD BY, ANY PERSON WHO IS, 
     WAS OR BECOMES AN ACQUIRING PERSON OR ANY AFFILIATE OR ASSOCIATE 
     THEREOF (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT), 
     WHETHER CURRENTLY HELD BY OR ON BEHALF OF SUCH PERSON OR BY ANY 
     SUBSEQUENT HOLDER, MAY BECOME NULL AND VOID.
     
With respect to such certificates containing the foregoing legend, until the 
earlier of (i) the Distribution Date or (ii) the Expiration Date, the Rights 
associated with the Common Shares represented by such certificates shall be 
evidenced by such certificates alone, and the surrender for transfer of any 
such certificate shall also constitute the transfer of the Rights associated 
with the Common Shares represented thereby.

                                       -8-

          (d)  In the event that the Company purchases or acquires any Common 
Shares after the Record Date but prior to the Distribution Date, any Rights 
associated with such Common Shares shall be deemed canceled and retired so 
that the Company shall not be entitled to exercise any Rights associated with 
the Common Shares which are no longer outstanding.

     Section 4.     FORM OF RIGHTS CERTIFICATES.

          (a)  The Rights Certificates (and the forms of election to purchase 
Common Shares and of assignment to be printed on the reverse thereof) shall 
be substantially in the form of Exhibit B hereto and may have such marks of 
identification or designation and such legends, summaries or endorsements 
printed thereon as the Company may deem appropriate and as are not 
inconsistent with the provisions of this Agreement, or as may be required to 
comply with any applicable law or with any rule or regulation made pursuant 
thereto or with any rule or regulation of any stock exchange or a national 
market system, on which the Rights may from time to time be listed or 
included, or to conform to usage.  Subject to the provisions of Section 11 
and Section 22 hereof, the Rights Certificates, whenever distributed, shall 
be dated as of the Record Date (or in the case of Rights issued with respect 
to Common Shares issued by the Company after the Record Date, as of the date 
of issuance of such Common Shares) and on their face shall entitle the 
holders thereof to purchase such number of one-thousandths of a Preferred 
Share as shall be set forth therein at the price set forth therein (such 
exercise price per one one-thousandth of a Preferred Share being hereinafter 
referred to as the "Exercise Price" and the aggregate Exercise Price of all 
Preferred Shares issuable upon exercise of one Right being hereinafter 
referred to as the "Total Exercise Price"), but the number and type of 
securities purchasable upon the exercise of each Right and the Exercise Price 
shall be subject to adjustment as provided herein.

          (b)  Any Rights Certificate issued pursuant to Section 3(a) or 
Section 22 hereof that represents Rights beneficially owned by:  (i) an 
Acquiring Person or any Associate or Affiliate of an Acquiring Person, (ii) a 
transferee of an Acquiring Person (or of any such Associate or Affiliate) who 
becomes a transferee after the Acquiring Person becomes such or (iii) a 
transferee of an Acquiring Person (or of any such Associate or Affiliate) who 
becomes a transferee prior to or concurrently with the Acquiring Person 
becoming such and receives such Rights pursuant to either (A) a transfer 
(whether or not for consideration) from the Acquiring Person to holders of 
equity interests in such Acquiring Person or to any Person with whom such 
Acquiring Person has any continuing agreement, arrangement or understanding 
regarding the transferred Rights or (B) a transfer which a majority of the 
Continuing Directors then in office has determined is part of a plan, 
arrangement or understanding which has as a primary purpose or effect 
avoidance of Section 7(e) hereof, and any Rights Certificate issued pursuant 
to Section 6 or Section 11 hereof upon transfer, exchange, replacement or 
adjustment of any other Rights Certificate referred to in this sentence, 
shall contain (to the extent feasible) the following legend:

     THE RIGHTS REPRESENTED BY THIS RIGHTS CERTIFICATE ARE OR WERE 
     BENEFICIALLY OWNED BY A PERSON WHO WAS OR BECAME AN ACQUIRING 
     PERSON OR AN AFFILIATE OR ASSOCIATE OF AN ACQUIRING PERSON (AS SUCH 
     TERMS ARE DEFINED IN THE RIGHTS AGREEMENT).  ACCORDINGLY, THIS 
     RIGHTS CERTIFICATE AND THE RIGHTS REPRE-

                                      -9-
<PAGE>

     SENTED HEREBY MAY BECOME NULL AND VOID IN THE CIRCUMSTANCES 
     SPECIFIED IN SECTION 7(e) OF THE RIGHTS AGREEMENT.
          
     Section 5.     COUNTERSIGNATURE AND REGISTRATION.

          (a)  The Rights Certificates shall be executed on behalf of the 
Company by its Chairman of the Board, its Chief Executive Officer, its Chief 
Financial Officer, its President or any Vice President, either manually or by 
facsimile signature, and by the Secretary or an Assistant Secretary of the 
Company, either manually or by facsimile signature, and shall have affixed 
thereto the Company's seal (if any) or a facsimile thereof.  The Rights 
Certificates shall be manually countersigned by the Rights Agent and shall 
not be valid for any purpose unless countersigned.  In case any officer of 
the Company who shall have signed any of the Rights Certificates shall cease 
to be such officer of the Company before countersignature by the Rights Agent 
and issuance and delivery by the Company, such Rights Certificates, 
nevertheless, may be countersigned by the Rights Agent and issued and 
delivered by the Company with the same force and effect as though the person 
who signed such Rights Certificates on behalf of the Company had not ceased 
to be such officer of the Company; and any Rights Certificate may be signed 
on behalf of the Company by any person who, at the actual date of the 
execution of such Rights Certificate, shall be a proper officer of the 
Company to sign such Rights Certificate, although at the date of the 
execution of this Rights Agreement any such person was not such an officer.

          (b)  Following the Distribution Date, the Rights Agent will keep or 
cause to be kept, at its office designated for such purposes, books for 
registration and transfer of the Rights Certificates issued hereunder.  Such 
books shall show the names and addresses of the respective holders of the 
Rights Certificates, the number of Rights evidenced on its face by each of 
the Rights Certificates and the date of each of the Rights Certificates.

     Section 6.     TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF
                    RIGHTS CERTIFICATES; MUTILATED, DESTROYED, LOST 
                    OR STOLEN RIGHTS CERTIFICATES.

          (a)  Subject to the provisions of Sections 7(e), 14 and 24 hereof, 
at any time after the Close of Business on the Distribution Date, and at or 
prior to the Close of Business on the Expiration Date, any Rights Certificate 
or Rights Certificates may be transferred, split up, combined or exchanged 
for another Rights Certificate or Rights Certificates, entitling the 
registered holder to purchase a like number of one-thousandths of a Preferred 
Share (or, following a Triggering Event, other securities, cash or other 
assets, as the case may be) as the Rights Certificate or Rights Certificates 
surrendered then entitled such holder to purchase.  Any registered holder 
desiring to transfer, split up, combine or exchange any Rights Certificate or 
Rights Certificates shall make such request in writing delivered to the 
Rights Agent, and shall surrender the Rights Certificate or Rights 
Certificates to be transferred, split up, combined or exchanged at the office 
of the Rights Agent designated for such purpose.  Neither the Rights Agent 
nor the Company shall be obligated to take any action whatsoever with respect 
to the transfer of any such surrendered Rights Certificate until the 
registered holder shall have completed and signed the certificate contained 
in the form of assignment on the reverse side of such Rights Certificate and 
shall have provided such additional evidence of the identity of the 
Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates 
thereof as the Company shall reasonably request.  Thereupon the 

                                      -10-
<PAGE>

Rights Agent shall, subject to Sections 7(e), 14 and 24 hereof, countersign 
and deliver to the person entitled thereto a Rights Certificate or Rights 
Certificates, as the case may be, as so requested. The Company may require 
payment of a sum sufficient to cover any tax or governmental charge that may 
be imposed in connection with any transfer, split up, combination or exchange 
of Rights Certificates.

          (b)  Upon receipt by the Company and the Rights Agent of evidence 
reasonably satisfactory to them of the loss, theft, destruction or mutilation 
of a Rights Certificate, and, in case of loss, theft or destruction, of 
indemnity or security reasonably satisfactory to them, and, at the Company's 
request, reimbursement to the Company and the Rights Agent of all reasonable 
expenses incidental thereto, and upon surrender to the Rights Agent and 
cancellation of the Rights Certificate if mutilated, the Company will make 
and deliver a new Rights Certificate of like tenor to the Rights Agent for 
delivery to the registered holder in lieu of the Rights Certificate so lost, 
stolen, destroyed or mutilated.

     Section 7.     EXERCISE OF RIGHTS; EXERCISE PRICE; EXPIRATION
                    DATE OF RIGHTS.

          (a)  Subject to Sections 7(e), 23(b) and 24(b) hereof, the 
registered holder of any Rights Certificate may exercise the Rights evidenced 
thereby (except as otherwise provided herein) in whole or in part at any time 
after the Distribution Date and prior to the Close of Business on the 
Expiration Date by surrender of the Rights Certificate, with the form of 
election to purchase on the reverse side thereof duly executed, to the Rights 
Agent at the office of the Rights Agent designated for such purpose, together 
with payment of the Exercise Price for each one-thousandth of a Preferred 
Share (or, following a Triggering Event, other securities, cash or other 
assets as the case may be) as to which the Rights are exercised.

          (b)  The Exercise Price for each one-thousandth of a Preferred 
Share issuable pursuant to the exercise of a Right shall initially be 
Twenty-Two Dollars ($22.00), shall be subject to adjustment from time to 
time as provided in Sections 11 and 13 hereof and shall be payable in lawful 
money of the United States of America in accordance with paragraph (c) below.

          (c)  Upon receipt of a Rights Certificate representing exercisable 
Rights, with the form of election to purchase duly executed, accompanied by 
payment of the Exercise Price for the number of one-thousandths of a 
Preferred Share (or, following a Triggering Event, other securities, cash or 
other assets as the case may be) to be purchased and an amount equal to any 
applicable transfer tax required to be paid by the holder of such Rights 
Certificate in accordance with Section 9(e) hereof, the Rights Agent shall, 
subject to Section 20(k) hereof, thereupon promptly (i) (A) requisition from 
any transfer agent of the Preferred Shares (or make available, if the Rights 
Agent is the transfer agent for the Preferred Shares) a certificate or 
certificates for the number of one-thousandths of a Preferred Share (or, 
following a Triggering Event, other securities, cash or other assets as the 
case may be) to be purchased and the Company hereby irrevocably authorizes 
its transfer agent to comply with all such requests or (B) if the Company 
shall have elected to deposit the total number of one-thousandths of a 
Preferred Share (or, following a Triggering Event, other securities, cash or 
other assets as the case may be) issuable upon exercise of the Rights 
hereunder with a depositary agent, requisition from the depositary agent 
depositary receipts representing such number of one-thousandths of a 
Preferred Share (or, following a Triggering Event, other securities, cash or 
other assets as the case may be) as are to be purchased (in which case 

                                       -11-
<PAGE>

certificates for the Preferred Shares (or, following a Triggering Event, 
other securities, cash or other assets as the case may be) represented by 
such receipts shall be deposited by the transfer agent with the depositary 
agent) and the Company hereby directs the depositary agent to comply with 
such request, (ii) when appropriate, requisition from the Company the amount 
of cash to be paid in lieu of issuance of fractional shares in accordance 
with Section 14 hereof, (iii) after receipt of such certificates or 
depositary receipts, cause the same to be delivered to or upon the order of 
the registered holder of such Rights Certificate, registered in such name or 
names as may be designated by such holder and (iv) when appropriate, after 
receipt thereof, deliver such cash to or upon the order of the registered 
holder of such Rights Certificate.  The payment of the Exercise Price (as 
such amount may be reduced (including to zero) pursuant to Section 11(a)(iii) 
hereof) and an amount equal to any applicable transfer tax required to be 
paid by the holder of such Rights Certificate in accordance with Section 9(e) 
hereof, may be made in cash or by certified bank check, cashier's check or 
bank draft payable to the order of the Company.  In the event that the 
Company is obligated to issue securities of the Company other than Preferred 
Shares, pay cash and/or distribute other property pursuant to Section 11(a) 
hereof, the Company will make all arrangements necessary so that such other 
securities, cash and/or other property are available for distribution by the 
Rights Agent, if and when appropriate.

          (d)  In case the registered holder of any Rights Certificate shall 
exercise less than all the Rights evidenced thereby, a new Rights Certificate 
evidencing Rights equivalent to the Rights remaining unexercised shall be 
issued by the Rights Agent to the registered holder of such Rights 
Certificate or to his or her duly authorized assigns, subject to the 
provisions of Section 14 hereof.

          (e)  Notwithstanding anything in this Agreement to the contrary, 
from and after the first occurrence of a Triggering Event, any Rights 
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of 
an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such 
Associate or Affiliate) who becomes a transferee after the Acquiring Person 
becomes such (a "Post-Event Transferee"), (iii) a transferee of an Acquiring 
Person (or of any such Associate or Affiliate) who becomes a transferee prior 
to or concurrently with the Acquiring Person becoming such and receives such 
Rights pursuant to either (A) a transfer (whether or not for consideration) 
from the Acquiring Person to holders of equity interests in such Acquiring 
Person or to any Person with whom the Acquiring Person has any continuing 
agreement, arrangement or understanding regarding the transferred Rights or 
(B) a transfer which a majority of the Continuing Directors then in office 
has determined is part of a plan, arrangement or understanding which has as a 
primary purpose or effect the avoidance of this Section 7(e) (a "Pre-Event 
Transferee") or (iv) any subsequent transferee receiving transferred Rights 
from a Post-Event Transferee or a Pre-Event Transferee, either directly or 
through one or more intermediate transferees, shall become null and void 
without any further action and no holder of such Rights shall have any rights 
whatsoever with respect to such Rights, whether under any provision of this 
Agreement or otherwise.  The Company shall use all reasonable efforts to 
ensure that the provisions of this Section 7(e) and Section 4(b) hereof are 
complied with, but shall have no liability to any holder of Rights 
Certificates or to any other Person as a result of its failure to make any 
determinations with respect to an Acquiring Person or any of such Acquiring 
Person's Affiliates, Associates or transferees hereunder.

          (f)  Notwithstanding anything in this Agreement to the contrary, 
neither the Rights Agent nor the Company shall be obligated to undertake any 
action with respect to a registered holder

                                       -12-

<PAGE>

upon the occurrence of any purported exercise as set forth in this Section 7 
unless such registered holder shall, in addition to having complied with the 
requirements of Section 7(a), have (i) completed and signed the certificate 
contained in the form of election to purchase set forth on the reverse side 
of the Rights Certificate surrendered for such exercise and (ii) provided 
such additional evidence of the identity of the Beneficial Owner (or former 
Beneficial Owner) or Affiliates or Associates thereof as the Company shall 
reasonably request.

     Section 8.  CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES.  All 
Rights Certificates surrendered for the purpose of exercise, transfer, split 
up, combination or exchange shall, if surrendered to the Company or to any of 
its agents, be delivered to the Rights Agent for cancellation or in canceled 
form, or, if surrendered to the Rights Agent, shall be canceled by it, and no 
Rights Certificates shall be issued in lieu thereof except as expressly 
permitted by any of the provisions of this Agreement.  The Company shall 
deliver to the Rights Agent for cancellation and retirement, and the Rights 
Agent shall so cancel and retire, any Rights Certificate purchased or 
acquired by the Company otherwise than upon the exercise thereof.  The Rights 
Agent shall deliver all canceled Rights Certificates to the Company, or 
shall, at the written request of the Company, destroy  such canceled Rights 
Certificates, and in such case shall deliver a certificate of destruction 
thereof to the Company.

     Section 9.  RESERVATION AND AVAILABILITY OF PREFERRED SHARES.

            (a)  The Company covenants and agrees that it will use its best 
efforts to cause to be reserved and kept available out of  its authorized and 
unissued Preferred Shares not reserved for another purpose (and, following 
the occurrence of a Triggering Event, out of its authorized and unissued 
Common Shares and/or other securities), the number of Preferred Shares (and, 
following the occurrence of the Triggering Event, Common Shares and/or other 
securities) that will be sufficient to permit the exercise in full of all 
outstanding Rights.

            (b)  If the Company shall hereafter list any of its Preferred 
Shares on a national securities exchange, then so long as the Preferred 
Shares (and, following the occurrence of a Triggering Event, Common Shares 
and/or other securities) issuable and deliverable upon exercise of the Rights 
may be listed on such exchange, the Company shall use its best efforts to 
cause, from and after such time as the Rights become exercisable (but only to 
the extent that it is reasonably likely that the Rights will be exercised), 
all shares reserved for such issuance to be listed on such exchange upon 
official notice of issuance upon such exercise.

            (c)  The Company shall use its best efforts to (i) file, as soon 
as practicable following the earliest date after the first occurrence of a 
Triggering Event in which the consideration to be delivered by the Company 
upon exercise of the Rights is described in Section 11(a)(ii) or Section 
11(a)(iii) hereof, or as soon as is required by law following the 
Distribution Date, as the case may be, a registration statement under the 
Securities Act with respect to the securities purchasable upon exercise of 
the Rights on an appropriate form, (ii) cause such registration statement to 
become effective as soon as practicable after such filing and (iii) cause 
such registration statement to remain effective (with a prospectus at all 
times meeting the requirements of the Securities Act) until the earlier of 
(A) the date as of which the Rights are no longer exercisable for such 
securities and (B) the date of expiration of the Rights.  The


                                     -13-
<PAGE>

Company may temporarily suspend, for a period not to exceed ninety (90) days 
after the date set forth in clause (i) of the first sentence of this Section 
9(c), the exercisability of the Rights in order to prepare and file such 
registration statement and permit it to become effective.  Upon any such 
suspension, the Company shall issue a public announcement stating, and notify 
the Rights Agent, that the exercisability of the Rights has been temporarily 
suspended, as well as a public announcement and notification to the Rights 
Agent at such time as the suspension is no longer in effect.  The Company 
will also take such action as may be appropriate under, or to ensure 
compliance with, the securities or "blue sky" laws of the various states in 
connection with the exercisability of the Rights.  Notwithstanding any 
provision of this Agreement to the contrary, the Rights shall not be 
exercisable in any jurisdiction, unless the requisite qualification in such 
jurisdiction shall have been obtained, or an exemption therefrom shall be 
available, and until a registration statement has been declared effective.

            (d)  The Company covenants and agrees that it will take all such 
action as may be necessary to ensure that all Preferred Shares (or other 
securities of the Company) delivered upon exercise of Rights shall, at the 
time of delivery of the certificates for such securities (subject to payment 
of the Exercise Price), be duly and validly authorized and issued and fully 
paid and nonassessable shares.

            (e)  The Company further covenants and agrees that it will pay 
when due and payable any and all federal and state transfer taxes and charges 
which may be payable in respect of the original issuance or delivery of the 
Rights Certificates or of any Preferred Shares (or other securities of the 
Company) upon the exercise of Rights.  The Company shall not, however, be 
required to pay any transfer tax which may be payable in respect of any 
transfer or delivery of Rights Certificates to a person other than, or the 
issuance or delivery of certificates or depositary receipts for the Preferred 
Shares (or other securities of the Company) in a name other than that of, the 
registered holder of the Rights Certificate evidencing Rights surrendered for 
exercise or to issue or to deliver any certificates or depositary receipts 
for Preferred Shares (or other securities of the Company) upon the exercise 
of any Rights until any such tax shall have been paid (any such tax being 
payable by the holder of such Rights Certificate at the time of surrender) or 
until it has been established to the Company's satisfaction that no such tax 
is due.

     Section 10. RECORD DATE.  Each Person in whose name any certificate for 
a number of one-thousandths of a Preferred Share (or other securities of the 
Company) is issued upon the exercise of Rights shall for all purposes be 
deemed to have become the holder of record of Preferred Shares (or other 
securities of the Company) represented thereby on, and such certificate shall 
be dated, the date upon which the Rights Certificate evidencing such Rights 
was duly surrendered and payment of the Total Exercise Price with respect to 
which the Rights have been exercised (and any applicable transfer taxes) was 
made; provided, however, that if the date of such surrender and payment is a 
date upon which the transfer books of the Company are closed, such Person 
shall be deemed to have become the record holder of such shares on, and such 
certificate shall be dated, the next succeeding Business Day on which the 
transfer books of the Company are open.  Prior to the exercise of the Rights 
evidenced thereby, the holder of a Rights Certificate shall not be entitled 
to any rights of a holder of Preferred Shares (or other securities of the 
Company) for which the Rights shall be exercisable, including, without 
limitation, the right to vote, to receive dividends or other distributions or 
to exercise any preemptive rights, and shall not be entitled to receive any 
notice of any proceedings of the Company, except as provided herein.

     Section 11. ADJUSTMENT OF EXERCISE PRICE, NUMBER OF SHARES OR NUMBER OF 
RIGHTS.  The Exercise Price, the number and kind of shares or other property 
covered by each Right and the number of Rights outstanding are subject to 
adjustment from time to time as provided in this Section 11.

            (a)  (i)   Anything in this Agreement to the contrary 
notwithstanding, in the event the Company shall at any time after the date of 
this Agreement (A) declare a dividend on the Preferred Shares payable in 
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine 
the outstanding Preferred Shares (by reverse stock split or otherwise) into a 
smaller number of Preferred Shares, or (D) issue any shares of its capital 
stock in a reclassification of the Preferred Shares (including any such 
reclassification in connection with a consolidation or merger in which the 
Company is the continuing or surviving corporation), then, in each such 
event, except as otherwise provided in this Section 11 and Section 7(e) 
hereof: (1) the Exercise Price in effect at the time of the record date for 
such dividend or of the effective date of such subdivision, combination or 
reclassification shall be adjusted so that the Exercise Price thereafter 
shall equal the result obtained by dividing the Exercise Price in effect 
immediately prior to such time by a fraction (the "Adjustment Fraction"), the 
numerator of which shall be the total number of Preferred Shares (or shares 
of capital stock issued in such reclassification of the Preferred Shares) 
outstanding immediately following such time and the denominator of which 
shall be the total number of Preferred Shares outstanding immediately prior 
to such time; provided, however, that in no event shall the consideration to 
be paid upon the exercise of one Right be less than the aggregate par value 
of the shares of capital stock of the Company issuable upon exercise of such 
Right; and (2) the number of one-thousandths of a Preferred Share (or share 
of such other capital stock) issuable upon the exercise of each Right shall 
equal the number of one-thousandths of a Preferred Share (or share of such 
other capital stock) as was issuable upon exercise of a Right immediately 
prior to the occurrence of the event described in clauses (A)-(D) of this 
Section 11(a)(i), multiplied by the Adjustment Fraction; provided, however, 
that, no such adjustment shall be made pursuant to this Section 11(a)(i) to 
the extent that there shall have simultaneously occurred an event described 
in clause (A), (B), (C) or (D) of Section 11(n) with a proportionate 
adjustment being made thereunder.  Each Common Share that shall become 
outstanding after an adjustment has been made pursuant to this Section 
11(a)(i) shall have associated with it the number of Rights, exercisable at 
the Exercise Price and for the number of one-thousandths of a Preferred Share 
(or shares of such other capital stock) as one Common Share has associated 
with it immediately following the adjustment made pursuant to this Section 
11(a)(i).

                 (ii)  Subject to Section 24 of this Agreement, in the event a 
Triggering Event shall have occurred, then promptly following such Triggering 
Event each holder of a Right, except as provided in Section 7(e) hereof, 
shall thereafter have the right to receive for each Right, upon exercise 
thereof in accordance with the terms of this Agreement and payment of the 
Exercise Price in effect immediately prior to the occurrence of the 
Triggering Event, in lieu of a number of one-thousandths of a Preferred 
Share, such number of Common Shares of the Company as shall equal the result 
obtained by multiplying the  Exercise Price in effect immediately prior to 
the occurrence of the Triggering Event by the number of one-thousandths of a 
Preferred Share for which a Right was exercisable (or would have been 
exercisable if the Distribution Date had occurred) immediately prior to the 
first occurrence of a Triggering Event, and dividing that product by 50% of 
the Current Per Share Market Price for Common Shares on the date of 
occurrence of the Triggering Event; provided, however, that the Exercise 
Price and the number of Common Shares of the Company so receivable upon 
exercise of a Right shall be subject


                                     -15-
<PAGE>

to further adjustment as appropriate in accordance with Section 11(e) hereof 
to reflect any events occurring in respect of the Common Shares of the 
Company after the occurrence of the Triggering Event. Notwithstanding the 
foregoing provisions of this Section 11(a)(ii), the right to buy Common 
Shares of the Company pursuant to Section 11(a)(ii) hereof shall not arise as 
a result of any Person becoming an Acquiring Person through an acquisition of 
Common Shares pursuant to a Permitted Offer.

                 (iii) In lieu of issuing Common Shares in accordance with 
Section 11(a)(ii) hereof, the Company may, if a majority of the Continuing 
Directors then in office determines that such action is necessary or 
appropriate and not contrary to the interest of holders of Rights and, in the 
event that the number of Common Shares which are authorized by the Company's 
Articles of Incorporation but not outstanding or reserved for issuance for 
purposes other than upon exercise of the Rights are not sufficient to permit 
the exercise in full of the Rights, or if any necessary regulatory approval 
for such issuance has not been obtained by the Company, the Company shall:  
(A) determine the excess of (1) the value of the Common Shares issuable upon 
the exercise of a Right (the "Current Value") over (2) the Exercise Price 
(such excess, the "Spread") and (B) with respect to each Right, make adequate 
provision to substitute for such Common Shares, upon exercise of the Rights, 
(1) cash, (2) a reduction in the Exercise Price, (3) other equity securities 
of the Company (including, without limitation, shares or units of shares of 
any series of preferred stock which a majority of the Continuing Directors 
then in office has deemed to have the same value as Common Shares (such 
shares or units of shares of preferred stock are herein called "Common Stock 
Equivalents")), except to the extent that the Company has not obtained any 
necessary stockholder or regulatory approval for such issuance, (4) debt 
securities of the Company, except to the extent that the Company has not 
obtained any necessary stockholder or regulatory approval for such issuance, 
(5) other assets or (6) any combination of the foregoing, having an aggregate 
value equal to the Current Value, where such aggregate value has been 
determined by a majority of the Continuing Directors then in office based 
upon the advice of a nationally recognized investment banking firm selected 
by a majority of the Continuing Directors then in office; provided, however, 
if the Company shall not have made adequate provision to deliver value 
pursuant to clause (B) above within thirty (30) days following the later of 
(x) the first occurrence of a Triggering Event and (y) the date on which the 
Company's right of redemption pursuant to Section 23(a) expires (the later of 
(x) and (y) being referred to herein as the "Section 11(a)(ii) Trigger 
Date"), then the Company shall be obligated to deliver, upon the surrender 
for exercise of a Right and without requiring payment of the Exercise Price, 
Common Shares (to the extent available), except to the extent that the 
Company has not obtained any necessary stockholder or regulatory approval for 
such issuance, and then, if necessary, cash, which shares and/or cash have an 
aggregate value equal to the Spread.  If a majority of the Continuing 
Directors then in office shall determine in good faith that it is likely that 
sufficient additional Common Shares could be authorized for issuance upon 
exercise in full of the Rights or that any necessary regulatory approval for 
such issuance will be obtained, the thirty (30) day period set forth above 
may be extended to the extent necessary, but not more than ninety (90) days 
after the Section 11(a)(ii) Trigger Date, in order that the Company may seek 
stockholder approval for the authorization of such additional shares or take 
action to obtain such regulatory approval (such period, as it may be 
extended, the "Substitution Period").  To the extent that the Company 
determines that some action need be taken pursuant to the first and/or second 
sentences of this Section 11(a)(iii), the Company (x) shall provide, subject 
to Section 7(e) hereof, that such action shall apply uniformly to all 
outstanding Rights and (y) may suspend the exercisability of the Rights until 
the expiration of the Substitution Period in order to seek any authorization 
of additional shares, to take


                                     -16-
<PAGE>

any action to obtain any required regulatory approval and/or to decide the 
appropriate form of distribution to be made pursuant to such first sentence 
and to determine the value thereof.  In the event of any such suspension, the 
Company shall issue a public announcement stating that the exercisability of 
the Rights has been temporarily suspended, as well as a public announcement 
at such time as the suspension is no longer in effect.  For purposes of this 
Section 11(a)(iii), the value of the Common Shares shall be the Current Per 
Share Market Price of the Common Shares on the Section 11(a)(ii) Trigger Date 
and the value of any Common Stock Equivalent shall be deemed to have the same 
value as the Common Shares on such date.

            (b)  In case the Company shall, at any time after the date of 
this Agreement, fix a record date for the issuance of rights, options or 
warrants to all holders of Preferred Shares entitling such holders (for a 
period expiring within forty-five (45) calendar days after such record date) 
to subscribe for or purchase Preferred Shares or Equivalent Shares or 
securities convertible into Preferred Shares or Equivalent Shares at a price 
per share (or having a conversion price per share, if a security convertible 
into Preferred Shares or Equivalent Shares) less than the then Current Per 
Share Market Price of the Preferred Shares or Equivalent Shares on such 
record date, then, in each such case, the Exercise Price to be in effect 
after such record date shall be determined by multiplying the Exercise Price 
in effect immediately prior to such record date by a fraction, the numerator 
of which shall be the number of Preferred Shares and Equivalent Shares (if 
any) outstanding on such record date, plus the number of Preferred Shares or 
Equivalent Shares, as the case may be, which the aggregate offering price of 
the total number of Preferred Shares or Equivalent Shares, as the case may 
be, to be offered or issued (and/or the aggregate initial conversion price of 
the convertible securities to be offered or issued) would purchase at such 
current market price, and the denominator of which shall be the number of 
Preferred Shares and Equivalent Shares (if any) outstanding on such record 
date, plus the number of additional Preferred Shares or Equivalent Shares, as 
the case may be, to be offered for subscription or purchase (or into which 
the convertible securities so to be offered are initially convertible); 
provided, however, that in no event shall the consideration to be paid upon 
the exercise of one Right be less than the aggregate par value of the shares 
of capital stock of the Company issuable upon exercise of one Right.  In case 
such subscription price may be paid in a consideration part or all of which 
shall be in a form other than cash, the value of such consideration shall be 
as determined in good faith by a majority of the Continuing Directors then in 
office, whose determination shall be described in a statement filed with the 
Rights Agent and shall be binding on the Rights Agent and the holders of the 
Rights. Preferred Shares and Equivalent Shares owned by or held for the 
account of the Company shall not be deemed outstanding for the purpose of any 
such computation. Such adjustment shall be made successively whenever such a 
record date is fixed, and in the event that such rights, options or warrants 
are not so issued, the Exercise Price shall be adjusted to be the Exercise 
Price which would then be in effect if such record date had not been fixed.

            (c)  In case the Company shall, at any time after the date of 
this Agreement, fix a record date for the making of a distribution to all 
holders of the Preferred Shares or of any class or series of Equivalent 
Shares (including any such distribution made in connection with a 
consolidation or merger in which the Company is the continuing or surviving 
corporation) of evidences of indebtedness or assets (other than a regular 
quarterly cash dividend, if any, or a dividend payable in Preferred Shares) 
or subscription rights, options or warrants (excluding those referred to in 
Section 11(b)), then, in each such case, the Exercise Price to be in effect 
after such record date shall be determined by multiplying the


                                     -17-
<PAGE>

Exercise Price in effect immediately prior to such record date by a fraction, 
the numerator of which shall be the Current Per Share Market Price of a 
Preferred Share or an Equivalent Share on such record date, less the fair 
market value per Preferred Share or Equivalent Share (as determined in good 
faith by the Board of Directors of the Company, whose determination shall be 
described in a statement filed with the Rights Agent) of the portion of the 
cash, assets or evidences of indebtedness so to be distributed or of such 
subscription rights or warrants applicable to a Preferred Share or Equivalent 
Share, as the case may be, and the denominator of which shall be such Current 
Per Share Market Price of a Preferred Share or Equivalent Share on such 
record date; provided, however, that in no event shall the consideration to 
be paid upon the exercise of one Right be less than the aggregate par value 
of the shares of capital stock of the Company issuable upon exercise of one 
Right.  Such adjustments shall be made successively whenever such a record 
date is fixed, and in the event that such distribution is not so made, the 
Exercise Price shall be adjusted to be the Exercise Price which would have 
been in effect if such record date had not been fixed.

            (d)  Anything herein to the contrary notwithstanding, no 
adjustment in the Exercise Price shall be required unless such adjustment 
would require an increase or decrease of at least 1% in the Exercise Price; 
provided, however, that any adjustments which by reason of this Section 11(d) 
are not required to be made shall be carried forward and taken into account 
in any subsequent adjustment.  All calculations under this Section 11 shall 
be made to the nearest cent or to the nearest ten-thousandth of a Common 
Share or other share or one hundred-thousandth of a Preferred Share, as the 
case may be.  Notwithstanding the first sentence of this Section 11(d), any 
adjustment required by this Section 11 shall be made no later than the 
earlier of (i) three (3) years from the date of the transaction which 
requires such adjustment or (ii) the Expiration Date.

            (e)  If as a result of an adjustment made pursuant to Section 
11(a) or 13(a) hereof, the holder of any Right thereafter exercised shall 
become entitled to receive any shares of capital stock other than Preferred 
Shares, thereafter the number of such other shares so receivable upon 
exercise of any Right and, if required, the Exercise Price thereof, shall be 
subject to adjustment from time to time in a manner and on terms as nearly 
equivalent as practicable to the provisions with respect to the Preferred 
Shares contained in Sections 11(a), 11(b), 11(c), 11(d), 11(g), 11(h), 11(i), 
11(j), 11(k) and 11(l), and the provisions of Sections 7, 9, 10, 13 and 14 
with respect to the Preferred Shares shall apply on like terms to any such 
other shares.

            (f)  All Rights originally issued by the Company subsequent to 
any adjustment made to the Exercise Price hereunder shall evidence the right 
to purchase, at the adjusted Exercise Price, the number of one-thousandths of 
a Preferred Share purchasable from time to time hereunder upon exercise of 
the Rights, all subject to further adjustment as provided herein.

            (g)  Unless the Company shall have exercised its election as 
provided in Section 11(h), upon each adjustment of the Exercise Price as a 
result of the calculations made in Section 11(b) and (c), each Right 
outstanding immediately prior to the making of such adjustment shall 
thereafter evidence the right to purchase, at the adjusted Exercise Price, 
that number of Preferred Shares (calculated to the nearest one 
hundred-thousandth of a share) obtained by (i) multiplying (x) the number of 
Preferred Shares covered by a Right immediately prior to this adjustment, by 
(y) the Exercise Price in effect immediately


                                     -18-

<PAGE>

prior to such adjustment of the Exercise Price, and (ii) dividing the product 
so obtained by the Exercise Price in effect immediately after such adjustment 
of the Exercise Price.

          (h)  The Company may elect on or after the date of any adjustment 
of the Exercise Price as a result of the calculations made in Section 11(b) 
or (c) to adjust the number of Rights, in substitution for any adjustment in 
the number of Preferred Shares purchasable upon the exercise of a Right.  
Each of the Rights outstanding after such adjustment of the number of Rights 
shall be exercisable for the number of one-thousandths of a Preferred Share 
for which a Right was exercisable immediately prior to such adjustment.  Each 
Right held of record prior to such adjustment of the number of Rights shall 
become that number of Rights (calculated to the nearest one 
hundred-thousandth) obtained by dividing the Exercise Price in effect 
immediately prior to adjustment of the Exercise Price by the Exercise Price 
in effect immediately after adjustment of the Exercise Price.  The Company 
shall make a public announcement of its election to adjust the number of 
Rights, indicating the record date for the adjustment, and, if known at the 
time, the amount of the adjustment to be made.  This record date may be the 
date on which the Exercise Price is adjusted or any day thereafter, but, if 
the Rights Certificates have been issued, shall be at least ten (10) days 
later than the date of the public announcement.  If Rights Certificates have 
been issued, upon each adjustment of the number of Rights pursuant to this 
Section 11(h), the Company shall, as promptly as practicable, cause to be 
distributed to holders of record of Rights Certificates on such record date 
Rights Certificates evidencing, subject to Section 14 hereof, the additional 
Rights to which such holders shall be entitled as a result of such 
adjustment, or, at the option of the Company, shall cause to be distributed 
to such holders of record in substitution and replacement for the Rights 
Certificates held by such holders prior to the date of adjustment, and upon 
surrender thereof, if required by the Company, new Rights Certificates 
evidencing all the Rights to which such holders shall be entitled after such 
adjustment.  Rights Certificates so to be distributed shall be issued, 
executed and countersigned in the manner provided for herein (and may bear, 
at the option of the Company, the adjusted Exercise Price) and shall be 
registered in the names of the holders of record of Rights Certificates on 
the record date specified in the public announcement.

          (i)  Irrespective of any adjustment or change in the Exercise Price 
or the number of Preferred Shares issuable upon the exercise of the Rights, 
the Rights Certificates theretofore and thereafter issued may continue to 
express the Exercise Price per one one-thousandth of a Preferred Share and 
the number of one-thousandths of a Preferred Share which were expressed in 
the initial Rights Certificates issued hereunder.

          (j)  Before taking any action that would cause an adjustment 
reducing the Exercise Price below the par or stated value, if any, of the 
number of one-thousandths of a Preferred Share issuable upon exercise of the 
Rights, the Company shall take any corporate action which may, in the opinion 
of its counsel, be necessary in order that the Company may validly and 
legally issue as fully paid and nonassessable shares such number of 
one-thousandths of a Preferred Share at such adjusted Exercise Price.

          (k)  In any case in which this Section 11 shall require that an 
adjustment in the Exercise Price be made effective as of a record date for a 
specified event, the Company may elect to defer until the occurrence of such 
event the issuing to the holder of any Right exercised after such record date 
of 

                                       -19-
<PAGE>

the number of one-thousandths of a Preferred Share and other capital stock 
or securities of the Company, if any, issuable upon such exercise over and 
above the number of one-thousandths of a Preferred Share and other capital 
stock or securities of the Company, if any, issuable upon such exercise on 
the basis of the Exercise Price in effect prior to such adjustment; provided, 
however, that the Company shall deliver to such holder a due bill or other 
appropriate instrument evidencing such holder's right to receive such 
additional shares (fractional or otherwise) upon the occurrence of the event 
requiring such adjustment.

          (l)  Anything in this Section 11 to the contrary notwithstanding, 
prior to the Distribution Date, the Company shall be entitled to make such 
reductions in the Exercise Price, in addition to those adjustments expressly 
required by this Section 11, as and to the extent that it in its sole 
discretion shall determine to be advisable in order that any (i) 
consolidation or subdivision of the Preferred or Common Shares, (ii) issuance 
wholly for cash of any Preferred or Common Shares at less than the current 
market price, (iii) issuance wholly for cash of Preferred or Common Shares or 
securities which by their terms are convertible into or exchangeable for 
Preferred or Common Shares, (iv) stock dividends or (v) issuance of rights, 
options or warrants referred to in this Section 11, hereafter made by the 
Company to holders of its Preferred or Common Shares shall not be taxable to 
such stockholders.

          (m)  The Company covenants and agrees that, after the Distribution 
Date, it will not, except as permitted by Sections 23, 24 or 27 hereof, take 
(or permit to be taken) any action if at the time such action is taken it is 
reasonably foreseeable that such action will diminish substantially or 
otherwise eliminate the benefits intended to be afforded by the Rights.

          (n)  In the event the Company shall at any time after the date of 
this Agreement (A) declare a dividend on the Common Shares payable in Common 
Shares, (B) subdivide the outstanding Common Shares, (C) combine the 
outstanding Common Shares (by reverse stock split or otherwise) into a 
smaller number of Common Shares, or (D) issue any shares of its capital stock 
in a reclassification of the Common Shares (including any such 
reclassification in connection with a consolidation or merger in which the 
Company is the continuing or surviving corporation), then, in each such 
event, except as otherwise provided in this Section 11(a) and Section 7(e) 
hereof: (1) each Common Share (or shares of capital stock issued in such 
reclassification of the Common Shares) outstanding immediately following such 
time shall have associated with it the number of Rights as were associated 
with one Common Share immediately prior to the occurrence of the event 
described in clauses (A)-(D) above; (2) the Exercise Price in effect at the 
time of the record date for such dividend or of the effective date of such 
subdivision, combination or reclassification shall be adjusted so that the 
Exercise Price thereafter shall equal the result obtained by multiplying the 
Exercise Price in effect immediately prior to such time by a fraction, the 
numerator of which shall be the total number of Common Shares outstanding 
immediately prior to the event described in clauses (A)-(D) above, and the 
denominator of which shall be the total number of Common Shares outstanding 
immediately after such event; provided, however, that in no event shall the 
consideration to be paid upon the exercise of one Right be less than the 
aggregate par value of the shares of capital stock of the Company issuable 
upon exercise of such Right; and (3) the number of one-thousandths of a 
Preferred Share (or shares of such other capital stock) issuable upon the 
exercise of each Right outstanding after such event shall equal the number of 
one-thousandths of a Preferred Share (or shares of such other capital stock) 
as were issuable with respect to one Right immediately prior to such event. 
Each Common Share that shall become outstanding after an adjustment has been 
made pursuant 

                                       -20-
<PAGE>

to this Section 11(n) shall have associated with it the number of Rights, 
exercisable at the Exercise Price and for the number of one-thousandths of a 
Preferred Share (or shares of such other capital stock) as one Common Share 
has associated with it immediately following the adjustment made pursuant to 
this Section 11(n).  If an event occurs which would require an adjustment 
under both this Section 11(n) and Section 11(a)(ii) hereof, the adjustment 
provided for in this Section 11(n) shall be in addition to, and shall be made 
prior to, any adjustment required pursuant to Section 11(a)(ii) hereof.

     Section 12.    CERTIFICATE OF ADJUSTED EXERCISE PRICE OR NUMBER OF 
SHARES.  Whenever an adjustment is made as provided in Sections 11 and 13 
hereof, the Company shall promptly (a) prepare a certificate setting forth 
such adjustment and a brief statement of the facts accounting for such 
adjustment, (b) file with the Rights Agent and with each transfer agent for 
the Preferred Shares a copy of such certificate and (c) mail a brief summary 
thereof to each holder of a Rights Certificate in accordance with Section 26 
hereof.  Notwithstanding the foregoing sentence, the failure of the Company 
to make such certification or give such notice shall not affect the validity 
of such adjustment or the force or effect of the requirement for such 
adjustment.  The Rights Agent shall be fully protected in relying on any such 
certificate and on any adjustment contained therein and shall not be deemed 
to have knowledge of such adjustment unless and until it shall have received 
such certificate.

     Section 13.    CONSOLIDATION, MERGER OR SALE OR TRANSFER OF
ASSETS OR EARNING POWER.

          (a)  In the event that, following a Triggering Event, directly or
indirectly:

                    (i)   the Company shall consolidate with, or merge with 
and into, any other Person (other than a wholly-owned Subsidiary of the 
Company in a transaction the principal purpose of which is to change the 
state of incorporation of the Company and which complies with Section 11(m) 
hereof);

                    (ii)  any Person shall consolidate with the Company, or 
merge with and into the Company and the Company shall be the continuing or 
surviving corporation of such consolidation or merger and, in connection with 
such merger, all or part of the Common Shares shall be changed into or 
exchanged for stock or other securities of any other person (or the Company); 
or

                    (iii) the Company shall sell or otherwise transfer 
(or one or more of its Subsidiaries shall sell or otherwise transfer), in one 
or more transactions, assets or earning power aggregating 50% or more of the 
assets or earning power of the Company and its Subsidiaries (taken as a 
whole) to any other Person or Persons (other than the Company or one or more 
of its wholly owned Subsidiaries in one or more transactions, each of which 
individually (and together) complies with Section 11(m) hereof),

                          then, concurrent with and in each such case, 

                          (A) each holder of a Right (except as provided in 
Section 7(e) hereof) shall thereafter have the right to receive, upon the 
exercise thereof at a price equal to the Total Exercise Price applicable 
immediately prior to the occurrence of the Section 13 Event in accordance 
with the terms 

                                       -21-
<PAGE>

of this Agreement, such number of validly authorized and issued, fully paid, 
nonassessable and freely tradeable Common Shares of the Principal Party (as 
hereinafter defined), free of any liens, encumbrances, rights of first 
refusal or other adverse claims, as shall be equal to the result obtained by 
dividing such Total Exercise Price by 50% of the Current Per Share Market 
Price of the Common Shares of such Principal Party on the date of 
consummation of such Section 13 Event, provided, however, that the Exercise 
Price and the number of Common Shares of such Principal Party so receivable 
upon exercise of a Right shall be subject to further adjustment as 
appropriate in accordance with Section 11(e) hereof;

                         (B)  such Principal Party shall thereafter be liable 
for, and shall assume, by virtue of such Section 13 Event, all the 
obligations and duties of the Company pursuant to this Agreement;

                         (C)  the term "Company" shall thereafter be deemed 
to refer to such Principal Party, it being specifically intended that the 
provisions of Section 11 hereof shall apply only to such Principal Party 
following the first occurrence of a Section 13 Event;

                         (D)  such Principal Party shall take such steps 
(including, but not limited to, the reservation of a sufficient number of its 
Common Shares) in connection with the consummation of any such transaction as 
may be necessary to ensure that the provisions hereof shall thereafter be 
applicable, as nearly as reasonably may be, in relation to its Common Shares 
thereafter deliverable upon the exercise of the Rights; and

                         (E)  upon the subsequent occurrence of any 
consolidation, merger, sale or transfer of assets or other extraordinary 
transaction in respect of such Principal Party, each holder of a Right shall 
thereupon be entitled to receive, upon exercise of a Right and payment of the 
Total Exercise Price as provided in this Section 13(a), such cash, shares, 
rights, warrants and other property which such holder would have been 
entitled to receive had such holder, at the time of such transaction, owned 
the Common Shares of the Principal Party receivable upon the exercise of such 
Right pursuant to this Section 13(a), and such Principal Party shall take 
such steps (including, but not limited to, reservation of shares of stock) as 
may be necessary to permit the subsequent exercise of the Rights in 
accordance with the terms hereof for such cash, shares, rights, warrants and 
other property.

                         (F)  For purposes hereof, the "earning power" of the 
Company and its Subsidiaries shall be determined in good faith by the 
Company's Board of Directors on the basis of the operating earnings of each 
business operated by the Company and its Subsidiaries during the three fiscal 
years preceding the date of such determination (or, in the case of any 
business not operated by the Company or any Subsidiary during three full 
fiscal years preceding such date, during the period such business was 
operated by the Company or any Subsidiary).


                                       -22-
<PAGE>
          (b)  For purposes of this Agreement, the term "Principal Party"
shall mean:

                    (i)  in the case of any transaction described in clause 
(i) or (ii) of Section 13(a) hereof: (A) the Person that is the issuer of the 
securities into which the Common Shares are converted in such merger or 
consolidation, or, if there is more than one such issuer, the issuer the 
Common Shares of which have the greatest aggregate market value of shares 
outstanding, or (B) if no securities are so issued, (x) the Person that is 
the other party to the merger, if such Person survives said merger, or, if 
there is more than one such Person, the Person the Common Shares of which 
have the greatest aggregate market value of shares outstanding or (y) if the 
Person that is the other party to the merger does not survive the merger, the 
Person that does survive the merger (including the Company if it survives) or 
(z) the Person resulting from the consolidation; and

                    (ii) in the case of any transaction described in clause 
(iii) of Section13(a) hereof, the Person that is the party receiving the 
greatest portion of the assets or earning power transferred pursuant to such 
transaction or transactions, or, if more than one Person that is a party to 
such transaction or transactions receives the same portion of the assets or 
earning power so transferred and each such portion would, were it not for the 
other equal portions, constitute the greatest portion of the assets or 
earning power so transferred, or if the Person receiving the greatest portion 
of the assets or earning power cannot be determined, whichever of such 
Persons is the issuer of Common Shares having the greatest aggregate market 
value of shares outstanding; provided, however, that in any such case 
described in the foregoing clause (b)(i) or (b)(ii), if the Common Shares of 
such Person are not at such time or have not been continuously over the 
preceding 12-month period registered under Section 12 of the Exchange Act, 
then (1) if such Person is a direct or indirect Subsidiary of another Person 
the Common Shares of which are and have been so registered, the term 
"Principal Party" shall refer to such other Person, or (2) if such Person is 
a Subsidiary, directly or indirectly, of more than one Person, the Common 
Shares of which are and have been so registered, the term "Principal Party" 
shall refer to whichever of such Persons is the issuer of Common Shares 
having the greatest aggregate market value of shares outstanding, or (3) if 
such Person is owned, directly or indirectly, by a joint venture formed by 
two or more Persons that are not owned, directly or indirectly by the same 
Person, the rules set forth in clauses (1) and (2) above shall apply to each 
of the owners having an interest in the venture as if the Person owned by the 
joint venture was a Subsidiary of both or all of such joint venturers, and 
the Principal Party in each such case shall bear the obligations set forth in 
this Section 13 in the same ratio as its interest in such Person bears to the 
total of such interests.

          (c)  The Company shall not consummate any Section 13 Event unless 
the Principal Party shall have a sufficient number of authorized Common 
Shares that have not been issued or reserved for issuance to permit the 
exercise in full of the Rights in accordance with this Section 13 and unless 
prior thereto the Company and such issuer shall have executed and delivered 
to the Rights Agent a supplemental agreement confirming that such Principal 
Party shall, upon consummation of such Section 13 Event, assume this 
Agreement in accordance with Sections 13(a) and 13(b) hereof, that all rights 
of first refusal or preemptive rights in respect of the issuance of Common 
Shares of such Principal Party upon exercise of outstanding Rights have been 
waived, that there are no rights, warrants, instruments or securities 
outstanding or any agreements or arrangements which, as a result of the 

                                       -23-
<PAGE>

consummation of such transaction, would eliminate or substantially diminish 
the benefits intended to be afforded by the Rights and that such transaction 
shall not result in a default by such Principal Party under this Agreement, 
and further providing that, as soon as practicable after the date of such 
Section 13 Event, such Principal Party will:

                    (i)  prepare and file a registration statement under the 
Securities Act with respect to the Rights and the securities purchasable upon 
exercise of the Rights on an appropriate form, use its best efforts to cause 
such registration statement to become effective as soon as practicable after 
such filing and use its best efforts to cause such registration statement to 
remain effective (with a prospectus at all times meeting the requirements of 
the Securities Act) until the Expiration Date, and similarly comply with 
applicable state securities laws;

                    (ii) use its best efforts to list (or continue the 
listing of) the Rights and the securities purchasable upon exercise of the 
Rights on a national securities exchange or to meet the eligibility 
requirements for quotation on Nasdaq and list (or continue the listing of) 
the Rights and the securities purchasable upon exercise of the Rights on 
Nasdaq; and

                    (iii)     deliver to holders of the Rights historical 
financial statements for such Principal Party which comply in all respects 
with the requirements for registration on Form 10 (or any successor form) 
under the Exchange Act.

     In the event that at any time after the occurrence of a Triggering Event 
some or all of the Rights shall not have been exercised at the time of a 
transaction described in this Section 13, the Rights which have not 
theretofore been exercised shall thereafter be exercisable in the manner 
described in Section 13(a) (without taking into account any prior adjustment 
required by Section 11(a)(ii)).

          (d)  In case the "Principal Party" for purposes of Section 13(b) 
hereof has provision in any of its authorized securities or in its 
certificate of incorporation or by-laws or other instrument governing its 
corporate affairs, which provision would have the effect of (i) causing such 
Principal Party to issue (other than to holders of Rights pursuant to Section 
13 hereof), in connection with, or as a consequence of, the consummation of a 
Section 13 Event, Common Shares or Equivalent Shares of such Principal Party 
at less than the then Current Per Share Market Price thereof or securities 
exercisable for, or convertible into, Common Shares or Equivalent Shares of 
such Principal Party at less than such then Current Per Share Market Price, 
or (ii) providing for any special payment, tax or similar provision in 
connection with the issuance of the Common Shares of such Principal Party 
pursuant to the provisions of Section 13 hereof, then, in such event, the 
Company hereby agrees with each holder of Rights that it shall not consummate 
any such transaction unless prior thereto the Company and such Principal 
Party shall have executed and delivered to the Rights Agent a supplemental 
agreement providing that the provision in question of such Principal Party 
shall have been canceled, waived or amended, or that the authorized 
securities shall be redeemed, so that the applicable provision will have no 
effect in connection with or as a consequence of, the consummation of the 
proposed transaction.

          (e)  The Company covenants and agrees that it shall not, at any 
time after the Distribution Date, effect or permit to occur any Section 13 
Event, if (i) at the time or immediately after

                                       -24-

<PAGE>

such Section 13 Event there are any rights, warrants or other instruments or 
securities outstanding or agreements in effect which would substantially 
diminish or otherwise eliminate the benefits intended to be afforded by the 
Rights, (ii) prior to, simultaneously with or immediately after such Section 
13 Event, the stockholders of the Person who constitutes, or would 
constitute, the "Principal Party" for purposes of Section 13(b) hereof shall 
have received a distribution of Rights previously owned by such Person or any 
of its Affiliates or Associates or (iii) the form or nature of organization 
of the Principal Party would preclude or limit the exercisability of the 
Rights.

          (f)  Notwithstanding anything in this Agreement to the contrary, 
Section 13 shall not be applicable to a transaction described in clauses (i) 
and (ii) of Section 13(a) if:  (i) such transaction is consummated with a 
Person or Persons who acquired Common Shares pursuant to a Permitted Offer 
(or a wholly-owned Subsidiary of any such Person or Persons); (ii) the price 
per share of Common Shares offered in such transaction is not less than the 
price per share of Common Shares paid to all holders of Common Shares whose 
shares were purchased pursuant to such Permitted Offer; and (iii) the form of 
consideration being offered to the remaining holders of Common Shares 
pursuant to such transaction is the same form as the form of consideration 
paid pursuant to such Permitted Offer.  Upon consummation of any such 
transaction contemplated by this Section 13(f), all Rights hereunder shall 
expire.

          (g)  The provisions of this Section 13 shall similarly apply to 
successive mergers or consolidations or sales or other transfers.

     Section 14.    FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

          (a)  The Company shall not be required to issue fractions of Rights 
or to distribute Rights Certificates which evidence fractional Rights.  In 
lieu of such fractional Rights, there shall be paid to the registered holders 
of the Rights Certificates with regard to which such fractional Rights would 
otherwise be issuable, an amount in cash equal to the same fraction of the 
current market value of a whole Right.  For the purposes of this Section 
14(a), the current market value of a whole Right shall be the closing price 
of the Rights for the Trading Day immediately prior to the date on which such 
fractional Rights would have been otherwise issuable, as determined pursuant 
to the second sentence of Section 1(k) hereof.

          (b)  The Company shall not be required to issue fractions of 
Preferred Shares (other than fractions that are integral multiples of one 
one-thousandth of a Preferred Share) upon exercise of the Rights or to 
distribute certificates which evidence fractional Preferred Shares (other 
than fractions that are integral multiples of one one-thousandth of a 
Preferred Share).  Interests in fractions of Preferred Shares in integral 
multiples of one one-thousandth of a Preferred Share may, at the election of 
the Company, be evidenced by depositary receipts, pursuant to an appropriate 
agreement between the Company and a depositary selected by it; provided, that 
such agreement shall provide that the holders of such depositary receipts 
shall have all the rights, privileges and preferences to which they are 
entitled as beneficial owners of the Preferred Shares represented by such 
depositary receipts.  In lieu of fractional Preferred Shares that are not 
integral multiples of one one-thousandth of a Preferred Share, the Company 
shall pay to the registered holders of Rights Certificates at the time such 
Rights are exercised as herein provided an amount in cash equal to the same 
fraction of the current market value of a Preferred Share.  

                                       -25-
<PAGE>

For purposes of this Section 14(b), the current market value of a Preferred 
Share shall be one thousand times the closing price of a Common Share (as 
determined pursuant to the second sentence of Section 1(k) hereof) for the 
Trading Day immediately prior to the date of such exercise.

          (c)  The Company shall not be required to issue fractions of Common 
Shares or to distribute certificates which evidence fractional Common Shares 
upon the exercise or exchange of Rights.   In lieu of such fractional Common 
Shares, the Company shall pay to the registered holders of Rights 
Certificates at the time such Rights are exercised as herein provided an 
amount in cash equal to the same fraction of the current market value of a 
Common Share.  For purposes of this Section 14(c), the current market value 
of a Common Share shall be the closing price of a Common Share (as determined 
pursuant to the second sentence of Section 1(k) hereof) for the Trading Day 
immediately prior to the date of such exercise. 

          (d)  The holder of a Right by the acceptance of the Right expressly 
waives his or her right to receive any fractional Rights or any fractional 
shares (other than fractions that are integral multiples of one 
one-thousandth of a Preferred Share) upon exercise of a Right.

     Section 15.    RIGHTS OF ACTION.  All rights of action in respect of 
this Agreement, excepting the rights of action given to the Rights Agent 
under Section 18 hereof, are vested in the respective registered holders of 
the Rights Certificates (and, prior to the Distribution Date, the registered 
holders of the Common Shares); and any registered holder of any Rights 
Certificate (or, prior to the Distribution Date, of the Common Shares), 
without the consent of the Rights Agent or of the holder of any other Rights 
Certificate (or, prior to the Distribution Date, of the Common Shares), may, 
in his or her own behalf and for his or her own benefit, enforce, and may 
institute and maintain any suit, action or proceeding against the Company to 
enforce, or otherwise act in respect of, his or her right to exercise the 
Rights evidenced by such Rights Certificate in the manner provided in such 
Rights Certificate and in this Agreement.  Without limiting the foregoing or 
any remedies available to the holders of Rights, it is specifically 
acknowledged that the holders of Rights would not have an adequate remedy at 
law for any breach of this Agreement and will be entitled to specific 
performance of the obligations under, and injunctive relief against actual or 
threatened violations of, the obligations of any Person subject to this 
Agreement.

     Section 16.     AGREEMENT OF RIGHTS HOLDERS.  Every holder of a Right, 
by accepting the same, consents and agrees with the Company and the Rights 
Agent and with every other holder of a Right that:

          (a)  prior to the Distribution Date, the Rights will be 
transferable only in connection with the transfer of the Common Shares;

          (b)  after the Distribution Date, the Rights Certificates are 
transferable only on the registry books of the Rights Agent if surrendered at 
the principal office or offices of the Rights Agent designated for such 
purposes, duly endorsed or accompanied by a proper instrument of transfer and 
with the appropriate forms and certificates fully executed; and

          (c)  subject to Sections 6(a) and 7(f) hereof, the Company and the 
Rights Agent may deem and treat the person in whose name the Rights 
Certificate (or, prior to the Distribution Date, the 

                                     -26-
<PAGE>

associated Common Shares certificate) is registered as the absolute owner 
thereof and of the Rights evidenced thereby (notwithstanding any notations of 
ownership or writing on the Rights Certificates or the associated Common 
Shares certificate made by anyone other than the Company or the Rights Agent) 
for all purposes whatsoever, and neither the Company nor the Rights Agent 
shall be affected by any notice to the contrary.

     Section 17.    RIGHTS CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER.  No 
holder, as such, of any Rights Certificate shall be entitled to vote, receive 
dividends or be deemed for any purpose to be the holder of the Preferred 
Shares or any other securities of the Company which may at any time be 
issuable on the exercise of the Rights represented thereby, nor shall 
anything contained herein or in any Rights Certificate be construed to confer 
upon the holder of any Rights Certificate, as such, any of the rights of a 
stockholder of the Company or any right to vote for the election of directors 
or upon any matter submitted to stockholders at any meeting thereof, or to 
give or withhold consent to any corporate action, or to receive notice of 
meetings or other actions affecting stockholders (except as provided in 
Section 25 hereof), or to receive dividends or subscription rights, or 
otherwise, until the Right or Rights evidenced by such Rights Certificate 
shall have been exercised in accordance with the provisions hereof.

     Section 18.    CONCERNING THE RIGHTS AGENT.

          (a)  The Company agrees to pay to the Rights Agent reasonable 
compensation for all services rendered by it hereunder and, from time to 
time, on demand of the Rights Agent, its reasonable expenses and counsel fees 
and other disbursements incurred in the administration and execution of this 
Agreement and the exercise and performance of its duties hereunder.  The 
Company also agrees to indemnify the Rights Agent for, and to hold it 
harmless against, any loss, liability or expense, incurred without 
negligence, bad faith or willful misconduct on the part of the Rights Agent, 
for anything done or omitted by the Rights Agent in connection with the 
acceptance and administration of this Agreement, including the costs and 
expenses of defending against any claim of liability in the premises.  In no 
event will the Rights Agent be liable for special, indirect, incidental or 
consequential loss or damage of any kind whatsoever, even if the Rights Agent 
has been advised of the possibility of such loss or damage. 

          (b)  The Rights Agent shall be protected and shall incur no 
liability for, or in respect of any action taken, suffered or omitted by it 
in connection with, its administration of this Agreement in reliance upon any 
Rights Certificate or certificate for the Preferred Shares or Common Shares 
or for other securities of the Company, instrument of assignment or transfer, 
power of attorney, endorsement, affidavit, letter, notice, direction, 
consent, certificate, statement or other paper or document reasonably 
believed by it to be genuine and to be signed, executed and, where necessary, 
verified or acknowledged, by the proper Person or Persons, or otherwise upon 
the advice of counsel as set forth in Section 20 hereof.

     Section 19.    MERGER OR CONSOLIDATION OR CHANGE OF NAME OF
RIGHTS AGENT.

          (a)  Any corporation into which the Rights Agent or any successor 
Rights Agent may be merged or with which it may be consolidated, or any 
corporation resulting from any merger or consolidation to which the Rights 
Agent or any successor Rights Agent shall be a party, or any corporation 
succeeding to the corporate trust business of the Rights Agent or any 
successor Rights Agent, shall be the successor to the Rights Agent under this 
Agreement without the execution or filing of any paper or any further act on 
the part of any of the parties hereto; provided, however, that such 
corporation would be eligible for appointment as a successor Rights Agent 
under the provisions of Section 21 hereof.  In case at the time such 
successor Rights Agent shall succeed to the agency created by this Agreement, 
any of the Rights Certificates shall have been countersigned but not 
delivered, any such successor Rights Agent may adopt the countersignature of 
the predecessor Rights Agent and deliver such Rights Certificates so 
countersigned; and in case at that time any of the Rights Certificates shall 
not have been countersigned, any successor Rights Agent may countersign such 
Rights Certificates either in the name of the predecessor Rights Agent or in 
the name of the successor Rights Agent; and in all such cases such Rights 
Certificates shall have the full force provided in the Rights Certificates 
and in this Agreement.

          (b)  In case at any time the name of the Rights Agent shall be 
changed and at such time any of the Rights Certificates shall have been 
countersigned but not delivered, the Rights Agent may adopt the 
countersignature under its prior name and deliver Rights Certificates so 
countersigned; and in case at that time any of the Rights Certificates shall 
not have been countersigned, the Rights Agent may countersign such Rights 
Certificates either in its prior name or in its changed name; and in all such 
cases such Rights Certificates shall have the full force provided in the 
Rights Certificates and in this Agreement.

     Section 20.    DUTIES OF RIGHTS AGENT.  The Rights Agent undertakes the 
duties and obligations imposed by this Agreement upon the following terms and 
conditions, by all of which the Company and the holders of Rights 
Certificates, by their acceptance thereof, shall be bound:

          (a)  The Rights Agent may consult with legal counsel (who may be 
legal counsel for the Company), and the written advice or opinion of such 
counsel shall be full and complete authorization and protection to the Rights 
Agent as to any action taken or omitted by it in good faith and in accordance 
with such written advice or opinion.

          (b)  Whenever in the performance of its duties under this Agreement 
the Rights Agent shall deem it necessary or desirable that any fact or matter 
(including, without limitation, the identity of any Acquiring Person and the 
determination of Current Per Share Market Price) be proved or established by 
the Company prior to taking or suffering any action hereunder, such fact or 
matter (unless other evidence in respect thereof be herein specifically 
prescribed) may be deemed to be conclusively proved and established by a 
certificate signed by any one of the Chairman of the Board, the Chief 
Executive Officer, the President, any Vice President, the Chief Financial 
Officer, the Secretary or any Assistant Secretary of the Company and 
delivered to the Rights Agent; and such certificate shall be full 
authorization to the Rights Agent for any action taken or suffered in good 
faith by it under the provisions of this Agreement in reliance upon such 
certificate.

                                       -28-
<PAGE>

          (c)  The Rights Agent shall be liable hereunder to the Company and 
any other Person only for its own negligence, bad faith or willful misconduct.

          (d)  The Rights Agent shall not be liable for or by reason of any 
of the statements of fact or recitals contained in this Agreement or in the 
Rights Certificates (except its countersignature thereof) or be required to 
verify the same, but all such statements and recitals are and shall be deemed 
to have been made by the Company only.

          (e)  The Rights Agent shall not be under any responsibility in 
respect of the validity of this Agreement or the execution and delivery 
hereof (except the due execution hereof by the Rights Agent) or in respect of 
the validity or execution of any Rights Certificate (except its 
countersignature thereof); nor shall it be responsible for any breach by the 
Company of any covenant or condition contained in this Agreement or in any 
Rights Certificate; nor shall it be responsible for any change in the 
exercisability of the Rights or any adjustment in the terms of the Rights 
(including the manner, method or amount thereof) provided for in Sections 3, 
11, 13, 23 or 24, or the ascertaining of the existence of facts that would 
require any such change or adjustment (except with respect to the exercise of 
Rights evidenced by Rights Certificates after receipt by the Rights Agent of 
a certificate furnished pursuant to Section 12 describing such change or 
adjustment); nor shall it by any act hereunder be deemed to make any 
representation or warranty as to the authorization or reservation of any 
Preferred Shares to be issued pursuant to this Agreement or any Rights 
Certificate or as to whether any Preferred Shares will, when issued, be 
validly authorized and issued, fully paid and nonassessable.

          (f)  The Company agrees that it will perform, execute, acknowledge 
and deliver or cause to be performed, executed, acknowledged and delivered 
all such further and other acts, instruments and assurances as may reasonably 
be required by the Rights Agent for the carrying out or performing by the 
Rights Agent of the provisions of this Agreement.

          (g)  The Rights Agent is hereby authorized and directed to accept 
instructions with respect to the performance of its duties hereunder from any 
one of the Chairman of the Board, the Chief Executive Officer, the President, 
any Vice President, the Chief Financial Officer, the Secretary or any 
Assistant Secretary of the Company, and to apply to such officers for advice 
or instructions in connection with its duties, and it shall not be liable for 
any action taken or suffered by it in good faith in accordance with 
instructions of any such officer or for any delay in acting while waiting for 
those instructions.  Any application by the Rights Agent for written 
instructions from the Company may, at the option of the Rights Agent, set 
forth in writing any action proposed to be taken or omitted by the Rights 
Agent under this Rights Agreement and the date on and/or after which such 
action shall be taken or such omission shall be effective.  The Rights Agent 
shall not be liable for any action taken by, or omission of, the Rights Agent 
in accordance with a proposal included in any such application on or after 
the date specified in such application (which date shall not be less than 
five (5) Business Days after the date any officer of the Company actually 
receives such application, unless any such officer shall have consented in 
writing to an earlier date) unless, prior to taking any such action (or the 
effective date in the case of an omission), the Rights Agent shall have 
received written instructions in response to such application specifying the 
action to be taken or omitted.

                                       -29-
<PAGE>

          (h)  The Rights Agent and any stockholder, director, officer or 
employee of the Rights Agent may buy, sell or deal in any of the Rights or 
other securities of the Company or become pecuniarily interested in any 
transaction in which the Company may be interested, or contract with or lend 
money to the Company or otherwise act as fully and freely as though it were 
not Rights Agent under this Agreement.  Nothing herein shall preclude the 
Rights Agent from acting in any other capacity for the Company or for any 
other legal entity.

          (i)  The Rights Agent may execute and exercise any of the rights or 
powers hereby vested in it or perform any duty hereunder either itself or by 
or through its attorneys or agents, and the Rights Agent shall not be 
answerable or accountable for any act, default, neglect or misconduct of any 
such attorneys or agents or for any loss to the Company resulting from any 
such act, default, neglect or misconduct, provided reasonable care was 
exercised in the selection and continued employment thereof.

          (j)  No provision of this Agreement shall require the Rights Agent 
to expend or risk its own funds or otherwise incur any financial liability in 
the performance of any of its duties hereunder or in the exercise of its 
rights if there shall be reasonable grounds for believing that repayment of 
such funds or adequate indemnification against such risk or liability is not 
reasonably assured to it.

          (k)  If, with respect to any Rights Certificate surrendered to the 
Rights Agent for exercise or transfer, the certificate attached to the form 
of assignment or form of election to purchase, as the case may be, has either 
not been completed or indicates an affirmative response to clause 1 and/or 2 
thereof, the Rights Agent shall not take any further action with respect to 
such requested exercise or transfer without first consulting with the Company.

     Section 21.    CHANGE OF RIGHTS AGENT.  The Rights Agent or any 
successor Rights Agent may resign and be discharged from its duties under 
this Agreement upon thirty (30) days' notice in writing mailed to the Company 
and to each transfer agent of the Preferred Shares and the Common Shares by 
registered or certified mail, and to the holders of the Rights Certificates 
by first-class mail.  The Company may remove the Rights Agent or any 
successor Rights Agent upon thirty (30) days' notice in writing, mailed to 
the Rights Agent or successor Rights Agent, as the case may be, and to each 
transfer agent of the Preferred Shares and the Common Shares by registered or 
certified mail, and to the holders of the Rights Certificates by first-class 
mail.  If the Rights Agent shall resign or be removed or shall otherwise 
become incapable of acting, the Company shall appoint a successor to the 
Rights Agent.  If the Company shall fail to make such appointment within a 
period of thirty (30) days after giving notice of such removal or after it 
has been notified in writing of such resignation or incapacity by the 
resigning or incapacitated Rights Agent or by the holder of a Rights 
Certificate (who shall, with such notice, submit his or her Rights 
Certificate for inspection by the Company), then the registered holder of any 
Rights Certificate may apply to any court of competent jurisdiction for the 
appointment of a new Rights Agent.  Any successor Rights Agent, whether 
appointed by the Company or by such a court, shall be a corporation organized 
and doing business under the laws of the United States or of any state of the 
United States, in good standing, which is authorized under such laws to 
exercise corporate trust or stockholder services powers and is subject to 
supervision or examination by federal or state authority and which has at the 
time of its appointment as Rights Agent a combined capital and surplus of at 
least $100 million.  After appointment, the successor Rights Agent shall be 
vested with the same powers, rights, duties and

                                       -30-


<PAGE>

responsibilities as if it had been originally named as Rights Agent without 
further act or deed; but the predecessor Rights Agent shall deliver and 
transfer to the successor Rights Agent any property at the time held by it 
hereunder, and execute and deliver any further assurance, conveyance, act or 
deed necessary for the purpose.  Not later than the effective date of any 
such appointment, the Company shall file notice thereof in writing with the 
predecessor Rights Agent and each transfer agent of the Preferred Shares and 
the Common Shares, and mail a notice thereof in writing to the registered 
holders of the Rights Certificates.  Failure to give any notice provided for 
in this Section 21, however, or any defect therein, shall not affect the 
legality or validity of the resignation or removal of the Rights Agent or the 
appointment of the successor Rights Agent, as the case may be.

     Section 22. ISSUANCE OF NEW RIGHTS CERTIFICATES. Notwithstanding any of 
the provisions of this Agreement or of the Rights to the contrary, the 
Company may, at its option, issue new Rights Certificates evidencing Rights 
in such form as may be approved by its Board of Directors to reflect any 
adjustment or change in the Exercise Price and the number or kind or class of 
shares or other securities or property purchasable under the Rights 
Certificates made in accordance with the provisions of this Agreement.  In 
addition, in connection with the issuance or sale of Common Shares following 
the Distribution Date and prior to the redemption or expiration of the 
Rights, the Company (a) shall, with respect to Common Shares so issued or 
sold pursuant to the exercise of stock options or under any employee plan or 
arrangement or upon the exercise, conversion or exchange of other securities 
of the Company outstanding at the date hereof or upon the exercise, 
conversion or exchange of securities hereinafter issued by the Company and 
(b) may, in any other case, if deemed necessary or appropriate by the Board 
of Directors of the Company, issue Rights Certificates representing the 
appropriate number of Rights in connection with such issuance or sale; 
provided, however, that (i) no such Rights Certificate shall be issued and 
this sentence shall be null and void ab initio if, and to the extent that, 
such issuance or this sentence would create a significant risk of or result 
in material adverse tax consequences to the Company or the Person to whom 
such Rights Certificate would be issued or would create a significant risk of 
or result in such options' or employee plans' or arrangements' failing to 
qualify for otherwise available special tax treatment and (ii) no such Rights 
Certificate shall be issued if, and to the extent that, appropriate 
adjustment shall otherwise have been made in lieu of the issuance thereof.

     Section 23. REDEMPTION.

             (a) The Company may, at its option and with the approval of the 
Board of Directors, at any time prior to the Close of Business on the earlier 
of (i) the tenth day following the Shares Acquisition Date (or such later 
date as may be determined by action of a majority of Continuing Directors 
then in office and publicly announced by the Company) and (ii) the Final 
Expiration Date, redeem all but not less than all the then outstanding Rights 
at a redemption price of $0.01 per Right, appropriately adjusted to reflect 
any stock split, stock dividend or similar transaction occurring after the 
date hereof (such redemption price being herein referred to as the 
"redemption price") and the Company may, at its option, pay the Redemption 
Price either in Common Shares (based on the Current Per Share Market Price 
thereof at the time of redemption) or cash. Such redemption of the Rights by 
the Company may be made effective at such time, on such basis and with such 
conditions as the Board of Directors in its sole discretion may establish; 
provided, however, if the Board of Directors of the Company authorizes 
redemption of the Rights on or after the time a Person becomes an Acquiring 
Person, then there must be


                                     -31-
<PAGE>

Continuing Directors then in office and such authorization shall require the 
concurrence of a majority of such Continuing Directors.  The date on which 
the Board of Directors elects to make the redemption effective shall be 
referred to as the "Redemption Date."

             (b) Immediately upon the action of the Board of Directors of the 
Company ordering the redemption of the Rights, evidence of which shall have 
been filed with the Rights Agent, and without any further action and without 
any notice, the right to exercise the Rights will terminate and the only 
right thereafter of the holders of Rights shall be to receive the Redemption 
Price.  The Company shall promptly give public notice of any such redemption; 
provided, however, that the failure to give or any defect in, any such notice 
shall not affect the validity of such redemption.  Within ten (10) days after 
the action of the Board of Directors ordering the redemption of the Rights, 
the Company shall give notice of such redemption to the Rights Agent and the 
holders of the then outstanding Rights by mailing such notice to all such 
holders at their last addresses as they appear upon the registry books of the 
Rights Agent or, prior to the Distribution Date, on the registry books of the 
transfer agent for the Common Shares. Any notice which is mailed in the 
manner herein provided shall be deemed given, whether or not the holder 
receives the notice.  Each such notice of redemption will state the method by 
which the payment of the Redemption Price will be made.  Neither the Company 
nor any of its Affiliates or Associates may redeem, acquire or purchase for 
value any Rights at any time in any manner other than that specifically set 
forth in this Section 23 or in Section 24 hereof, and other than in 
connection with the purchase of Common Shares prior to the Distribution Date.

     Section 24. EXCHANGE.

             (a) Subject to applicable laws, rules and regulations, and 
subject to subsection 24(c) below, the Company may, at its option, by 
majority vote of the Board of Directors and a majority vote of the Continuing 
Directors, at any time after the occurrence of a Triggering Event, exchange 
all or part of the then outstanding and exercisable Rights (which shall not 
include Rights that have become void pursuant to the provisions of Section 
7(e) hereof) for Common Shares at an exchange ratio of one Common Share per 
Right, appropriately adjusted to reflect any stock split, stock dividend or 
similar transaction occurring after the date hereof (such exchange ratio 
being hereinafter referred to as the "Exchange Ratio").  Notwithstanding the 
foregoing, the Board of Directors shall not be empowered to effect such 
exchange at any time after any Person (other than the Company, any Subsidiary 
of the Company, any employee benefit plan of the Company or any such 
Subsidiary, or any entity holding Common Shares for or pursuant to the terms 
of any such plan), together with all Affiliates and Associates of such 
Person, becomes the Beneficial Owner of 50% or more of the Common Shares then 
outstanding.

             (b) Immediately upon the action of the Board of Directors 
ordering the exchange of any Rights pursuant to subsection 24(a) of this 
Section 24 and without any further action and without any notice, the right 
to exercise such Rights shall terminate and the only right thereafter of a 
holder of such Rights shall be to receive that number of Common Shares equal 
to the number of such Rights held by such holder multiplied by the Exchange 
Ratio.  The Company shall give public notice of any such exchange; provided, 
however, that the failure to give, or any defect in, such notice shall not 
affect the validity of such exchange.  The Company shall mail a notice of any 
such exchange to all of the holders of such Rights at their last addresses as 
they appear upon the registry books of the Rights Agent.  Any


                                     -32-
<PAGE>

notice which is mailed in the manner herein provided shall be deemed given, 
whether or not the holder receives the notice.  Each such notice of exchange 
will state the method by which the exchange of the Common Shares for Rights 
will be effected and, in the event of any partial exchange, the number of 
Rights which will be exchanged.  Any partial exchange shall be effected pro 
rata based on the number of Rights (other than Rights which have become void 
pursuant to the provisions of Section 7(e) hereof) held by each holder of 
Rights.

             (c) In the event that there shall not be sufficient Common 
Shares issued but not outstanding or authorized but unissued to permit any 
exchange of Rights as contemplated in accordance with Section 24(a), the 
Company shall either take such action as may be necessary to authorize 
additional Common Shares for issuance upon exchange of the Rights or 
alternatively, at the option of a majority of the Board of Directors, with 
respect to each Right (i) pay cash in an amount equal to the Current Value 
(as hereinafter defined), in lieu of issuing Common Shares in exchange 
therefor, or (ii) issue debt or equity securities or a combination thereof, 
having a value equal to the Current Value, in lieu of issuing Common Shares 
in exchange for each such Right, where the value of such securities shall be 
determined by a nationally recognized investment banking firm selected by 
majority vote of the Board of Directors, or (iii) deliver any combination of 
cash, property, Common Shares and/or other securities having a value equal to 
the Current Value in exchange for each Right.  For purposes of this Section 
24(c) only, the Current Value shall mean the product of the Current Per Share 
Market Price of Common Shares on the date of the occurrence of the event 
described above in subparagraph (a), multiplied by the number of Common 
Shares for which the Right otherwise would be exchangeable if there were 
sufficient shares available.  To the extent that the Company determines that 
some action need be taken pursuant to clauses (i), (ii) or (iii) of this 
Section 24(c), the Board of Directors may temporarily suspend the 
exercisability of the Rights for a period of up to sixty (60) days following 
the date on which the event described in Section 24(a) shall have occurred, 
in order to seek any authorization of additional Common Shares and/or to 
decide the appropriate form of distribution to be made pursuant to the above 
provision and to determine the value thereof.  In the event of any such 
suspension, the Company shall issue a public announcement stating that the 
exercisability of the Rights has been temporarily suspended.

             (d) The Company shall not be required to issue fractions of 
Common Shares or to distribute certificates which evidence fractional Common 
Shares.  In lieu of such fractional Common Shares, there shall be paid to the 
registered holders of the Rights Certificates with regard to which such 
fractional Common Shares would otherwise be issuable, an amount in cash equal 
to the same fraction of the current market value of a whole Common Share (as 
determined pursuant to the second sentence of Section 1(k) hereof).

             (e) The Company may, at its option, by majority vote of the 
Board of Directors, at any time before any Person has become an Acquiring 
Person, exchange all or part of the then outstanding Rights for rights of 
substantially equivalent value, as determined reasonably and with good faith 
by the Board of Directors, based upon the advice of one or more nationally 
recognized investment banking firms.

             (f) Immediately upon the action of the Board of Directors

supplemented or amended to lengthen, pursuant to clause (iii) of this 
sentence, (A) a time period relating to when the Rights may be redeemed at

unless such lengthening is for the purpose of protecting, enhancing or 
clarifying the rights of, and/or the benefits to, the holders of Rights 
(other than an Acquiring Person or an Affiliate or Associate of an Acquiring 
Person).  Upon the delivery of a certificate from an appropriate officer of 
the Company that states that the proposed supplement or amendment is in 
compliance with the terms of this Section 27, the Rights Agent shall execute 
such supplement or amendment.  Prior to the Distribution Date, the interests 
of the holders of Rights shall be deemed coincident with the interests of the 
holders of Common Shares.

     Section 28. SUCCESSORS.  All the covenants and provisions of this 
Agreement by or for the benefit of the Company or the Rights Agent shall bind

For all purposes of this Agreement, any calculation of the number of Common

determining the particular percentage of such outstanding Common Shares of 
which any Person is the Beneficial Owner, shall be made in accordance with 
the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations 
under the Exchange Act.  The Board of Directors of the Company (or, where 
specifically provided for herein, the Continuing Directors) shall have the 
exclusive power and authority to administer this Agreement and to exercise 
all rights and powers specifically granted to the Board, or the Company (or, 
where specifically provided for herein, the Continuing Directors), or as may 
be necessary or advisable in the administration of this Agreement,


                                     -35-
<PAGE>

including, without limitation, the right and power to (i) interpret the 
provisions of this Agreement and (ii) make all determinations deemed 
necessary or advisable for the administration of this Agreement (including a 
determination to redeem or not redeem the Rights or to amend the Agreement).  
All such actions, calculations, interpretations and determinations 
(including, for purposes of clause (y) below, all omissions with respect to 
the foregoing) which are done or made by the Board (or, where specifically 
provided for herein, by the Continuing Directors) in good faith, shall (x) be 
final, conclusive and binding on the Company, the Rights Agent, the holders 
of the Rights Certificates and all other parties and (y) not subject the 
Board or the Continuing Directors to any liability to the holders of the 
Rights.

     Section 30. BENEFITS OF THIS AGREEMENT.  Nothing in this Agreement shall 
be construed to give to any Person other than the Company, the Rights Agent 
and the registered holders of the Rights Certificates (and, prior to the 
Distribution Date, the Common Shares) any legal or equitable right, remedy or 
claim under this Agreement; but this Agreement shall be for the sole and 
exclusive benefit of the Company, the Rights Agent and the registered holders 
of the Rights Certificates (and, prior to the Distribution Date, the Common 
Shares).

     Section 31. SEVERABILITY.  If any term, provision, covenant or 
restriction of this Agreement is held by a court of competent jurisdiction or 
other authority to be invalid, void or unenforceable, the remainder of the 
terms, provisions, covenants and restrictions of this Agreement shall remain 
in full force and effect and shall in no way be affected, impaired or 
invalidated; provided, however, that notwithstanding anything in this 
Agreement to the contrary, if any such term, provision, covenant or 
restriction is held by such court or authority to be invalid, void or 
unenforceable and the Board of Directors of the Company determines in its 
good faith judgment that severing the invalid language from this Agreement 
would adversely affect the purpose or effect of this Agreement, the right of 
redemption set forth in Section 23 hereof shall be reinstated and shall not 
expire until the Close of Business on the tenth day following the date of 
such determination by the Board of Directors.

     Section 32. GOVERNING LAW.  This Agreement and each Right and each

but one and the same instrument.

     Section 34. DESCRIPTIVE HEADINGS.  Descriptive headings of the several 
Sections of this Agreement are inserted for convenience only and shall not 
control or affect the meaning or construction of any of the provisions hereof.

the General Corporation Law of the State of Nevada, in accordance with the 
provisions of Section 78.195 of the Nevada Revised Statutes thereof, DO HEREBY

"Corporation").

     2.   That pursuant to the authority conferred upon the Board of 
Directors by the Restated Articles of Incorporation of the said Corporation, 
the said Board of Directors, at a meeting duly held and convened on January 
9, 1997, adopted the following resolution creating a series of Twenty 
Thousand (20,000) shares of Preferred Stock designated as Series A 
Participating Preferred Stock and declared such resolution to be advisable:

     "RESOLVED, that pursuant to the authority vested in the Board of 
Directors of this Corporation in accordance with the provisions of its 
Restated Articles of Incorporation, a series of Preferred Stock of the 
Corporation be and it hereby is created, such series of Preferred Stock to 
be designated "Series A Participating Preferred Stock," initially consisting 
of 20,000 shares with a par value of $.001 per share and, to the extent that 
the designations, powers, preferences and relative and other special rights 
and the qualifications, limitations and restrictions of the Series A 
Preferred Stock are not stated and expressed in the Restated Articles of 
Incorporation, does hereby fix and herein state and express the designations, 
powers, preferences and relative and other special rights and the 
qualifications, limitations and restrictions of such series of Preferred 
Stock as follows:

     Section 1.     DESIGNATION AND AMOUNT.  The shares of such series shall

shall at any time after the issuance of any share or shares of Series A 
Participating Preferred Stock (i) declare any dividend on Common Stock of the 
Corporation ("Common Stock") payable in shares of Common Stock, (ii) 
subdivide the outstanding Common Stock or (iii) combine the outstanding 
Common Stock into a smaller number of shares, then in each such case the 
Corporation shall simultaneously effect a proportional adjustment to the 
number of outstanding shares of Series A Participating Preferred Stock.

<PAGE>

     Section 3.     DIVIDENDS AND DISTRIBUTIONS.

          (a)  Subject to the prior and superior right of the holders of any 
shares of any series of Preferred Stock ranking prior and superior to the 
shares of Series A Participating Preferred Stock with respect to dividends, 
the holders of shares of Series A Participating Preferred Stock shall be 
entitled to receive when, as and if declared by the Board of Directors out of 
funds legally available for the purpose, quarterly dividends payable in cash 
on the last day of January, April, July and October in each year (each such 
date being referred to herein as a "Quarterly Dividend Payment Date"), 
commencing on the first Quarterly Dividend Payment Date after the first 
issuance of a share or fraction of a share of Series A Participating 
Preferred Stock, in an amount per share (rounded to the nearest cent) equal 
to 1,000 times the aggregate per share amount of all cash dividends, and 
1,000 times the aggregate per share amount (payable in kind) of all non-cash 
dividends or other distributions other than a dividend payable in shares of 
Common Stock or a subdivision of the outstanding shares of Common Stock (by 
reclassification or otherwise), declared on the Common Stock since the 
immediately preceding Quarterly Dividend Payment Date, or, with respect to 
the first Quarterly Dividend Payment Date, since the first issuance of any 
share or fraction of a share of Series A Participating Preferred Stock.

          (b)  The Corporation shall declare a dividend or distribution on 
the Series A Participating Preferred Stock as provided in paragraph (a) above 
immediately after it declares a dividend or distribution on the Common Stock 
(other than a dividend payable in shares of Common Stock).

          (c)  Dividends shall begin to accrue on outstanding shares of 
Series A Participating Preferred Stock from the Quarterly Dividend Payment 
Date next preceding the date of issue of such shares of Series A 
Participating Preferred Stock, unless the date of issue of such shares is 
prior to the record date for the first Quarterly Dividend Payment Date, in 
which case dividends on such shares shall begin to accrue from the date of 
issue of such shares, or unless the date of issue is a Quarterly Dividend 
Payment Date or is a date after the record date for the determination of 
holders of shares of Series A Participating Preferred Stock entitled to 
receive a quarterly dividend and before such Quarterly Dividend Payment Date, 
in either of which events such dividends shall begin to accrue from such 
Quarterly Dividend Payment Date.  Accrued but unpaid dividends shall not bear 
interest.  Dividends paid on the shares of Series A Participating Preferred 
Stock in an amount less than the total amount of such dividends at the time 
accrued and payable on such shares shall be allocated pro rata on a 
share-by-share basis among all such shares at the time outstanding.  The 
Board of Directors may fix a record date for the determination of holders of 
shares of Series A Participating Preferred Stock entitled to receive payment 
of a dividend or distribution declared thereon, which record date shall be no 
more than 30 days prior to the date fixed for the payment thereof.

     Section 4.     VOTING RIGHTS.  The holders of shares of Series A 
Participating Preferred Stock shall have the following voting rights:

          (a)  Each share of Series A Participating Preferred Stock shall 
entitle the holder thereof to 1,000 votes on all matters submitted to a vote 
of the stockholders of the Corporation.

shares of Series A Participating Preferred Stock and the holders of shares of 
Common Stock shall vote together as one class on all matters submitted to a 
vote of stockholders of the Corporation.

          (c)  Except as required by law, holders of Series A Participating 
Preferred Stock shall have no special voting rights and their consent shall 
not be required (except to the extent they are entitled to vote with holders 
of Common Stock as set forth herein) for taking any corporate action.

     Section 5.     CERTAIN RESTRICTIONS.

          (a)  The Corporation shall not declare any dividend on, make any 
distribution on, or redeem or purchase or otherwise acquire for consideration 
any shares of Common Stock after the first issuance of a share or fraction of 
a share of Series A Participating Preferred Stock unless concurrently 
therewith it shall declare a dividend on the Series A Participating Preferred 
Stock as required by Section 3 hereof.

          (b)  Whenever quarterly dividends or other dividends or 
distributions payable on the Series A Participating Preferred Stock as 
provided in Section 3 are in arrears, thereafter and until all accrued and 
unpaid dividends and distributions, whether or not declared, on shares of 
Series A Participating Preferred Stock outstanding shall have been paid in 
full, the Corporation shall not

                    (i)  declare or pay dividends on, make any other 
distributions on, or redeem or purchase or otherwise acquire for 
consideration any shares of stock ranking junior (either as to dividends or 
upon liquidation, dissolution or winding up) to the Series A Participating 
Preferred Stock;

                    (ii) declare or pay dividends on, make any other 
distributions on any shares of stock ranking on a parity (either as to 
dividends or upon liquidation, dissolution or winding up) with Series A 
Participating Preferred Stock, except dividends paid ratably on the Series A 
Participating Preferred Stock and all such parity stock on which dividends 
are payable or in arrears in proportion to the total amounts to which the 
holders of all such shares are then entitled;

                    (iii) redeem or purchase or otherwise acquire for 
consideration shares of any stock ranking on a parity (either as to dividends 
or upon liquidation, dissolution or winding up) with the Series A 
Participating Preferred Stock, provided that the Corporation may at any time 
redeem, purchase or otherwise acquire shares of any such parity stock in 
exchange for shares of any stock of the Corporation ranking junior (either as 
to dividends or upon dissolution, liquidation or winding up) to the Series A 
Participating Preferred Stock;

                    (iv) purchase or otherwise acquire for consideration any 
shares of Series A Participating Preferred Stock, or any shares of stock 
ranking on a parity with the Series A Participating Preferred Stock, except 
in accordance with a purchase offer made in writing or by publication (as 
determined by the Board of Directors) to all holders of such shares upon such 
terms as the Board of Directors, after consideration of the respective annual 
dividend rates and other relative rights and 

                                       -3-
<PAGE>

preferences of the respective series and classes, shall determine in good 
faith will result in fair and equitable treatment among the respective series 
or classes.

          (c)  The Corporation shall not permit any subsidiary of the 
Corporation to purchase or otherwise acquire for consideration any shares of 
stock of the Corporation unless the Corporation could, under paragraph (a) of 
this Section 5, purchase or otherwise acquire such shares at such time and in 
such manner.

     Section 6.     REACQUIRED SHARES.  Any shares of Series A Participating 
Preferred Stock purchased or otherwise acquired by the Corporation in any 
manner whatsoever shall be retired and canceled promptly after the 
acquisition thereof.  All such shares shall upon their cancellation become 
authorized but unissued shares of Preferred Stock and may be reissued as part 
of a new series of Preferred Stock to be created by resolution or resolutions 
of the Board of Directors, subject to the conditions and restrictions on 
issuance set forth herein and, in the Restated Certificate of Incorporation, 
as then amended.

     Section 7.     LIQUIDATION, DISSOLUTION OR WINDING UP.  Upon any 
liquidation, dissolution or winding up of the Corporation, the holders of 
shares of Series A Participating Preferred Stock shall be entitled to receive 
an aggregate amount per share equal to 1000 times the aggregate amount to be 
distributed per share to holders of shares of Common Stock plus an amount 
equal to any accrued and unpaid dividends on such shares of Series A 
Participating Preferred Stock.

     Section 8.     CONSOLIDATION, MERGER, ETC.  In case the Corporation 
shall enter into any consolidation, merger, combination or other transaction 
in which the shares of Common Stock are exchanged for or changed into other 
stock or securities, cash and/or any other property, then in any such case 
the shares of Series A Participating Preferred Stock shall at the same time 
be similarly exchanged or changed in an amount per share equal to 1,000 times 
the aggregate amount of stock, securities, cash and/or any other property 
(payable in kind), as the case may be, into which or for which each share of 
Common Stock is changed or exchanged.

     Section 9.     NO REDEMPTION.  The shares of Series A Participating 
Preferred Stock shall not be redeemable.

     Section 10.    RANKING.  The Series A Participating Preferred Stock 
shall rank junior to all other series of the Corporation's Preferred Stock as 
to the payment of dividends and the distribution of assets, unless the terms 
of any such series shall provide otherwise.

     Section 11.    AMENDMENT.  The Restated Articles of Incorporation of 
the Corporation shall not be further amended in any manner which would 
materially alter or change the powers, preference or special rights of the 
Series A Participating Preferred Stock so as to affect them adversely without 
the affirmative vote of the holders of a majority of the outstanding shares 
of Series A Participating Preferred Stock, voting separately as a class.

                                       -4-
<PAGE>

     Section 12.    FRACTIONAL SHARES.  Series A Participating Preferred 
Stock may be issued in fractions of a share which shall entitle the holder, 
in proportion to such holder's fractional shares, to exercise voting rights, 
receive dividends, participate in distributions and to have the benefit of 
all other rights of holders of Series A Participating Preferred Stock.

     RESOLVED FURTHER, that the President or any Vice President and the 
Secretary or any Assistant Secretary of this corporation be, and they hereby 
are, authorized and directed to prepare and file a Certificate of Designation

                     STOCKHOLDER RIGHTS PLAN
                LORONIX INFORMATION SYSTEMS, INC.


                        SUMMARY OF RIGHTS

DISTRIBUTION AND    The Board of Directors has declared a dividend of one       
TRANSFER OF RIGHTS; Right for each share of Loronix Information Systems, Inc.   
RIGHTS CERTIFICATE: Common Stock outstanding.  Prior to the Distribution Date   
                    referred to below, the Rights will be evidenced by and      
                    trade with the certificates for the Common Stock.  After the
                    Distribution Date, Loronix Information Systems, Inc. (the   
                    "Company") will mail Rights certificates to the             
                    Company's stockholders and the Rights will become           
                    transferable apart from the Common Stock.                   

DISTRIBUTION DATE:  Rights will separate from the Common Stock and become
                    exercisable following (a) the tenth day (or such later date
                    as may be determined by a majority of the Directors not
                    affiliated with the acquiring person or group (the
                    "Continuing Directors")) after a person or group
                    acquires beneficial ownership of 15% or more of the
                    Company's Common Stock or (b) the tenth business day (or
                    such later date as may be determined by a majority of the
                    Continuing Directors) after a person or group announces a
                    tender or exchange offer, the consummation of which
                    would result in ownership by a person or group of 15% or
                    more of the Company's Common Stock.

PREFERRED STOCK     After the Distribution Date, each Right will entitle the  
PURCHASABLE UPON    holder to purchase for $22.00 (the "Exercise Price"), a 
EXERCISE OF RIGHTS: fraction of a share of the Company's Preferred Stock with 
                    economic terms similar to that of one share of the Company's
                    Common Stock.                               

FLIP-IN:            If an acquiror (an "Acquiring Person") obtains 15% or 
                    more of the Company's Common Stock (other than pursuant 
                    to a tender offer deemed adequate and in the best 
                    interests of the Company and its stockholders by the 
                    Continuing Directors (a "Permitted Offer")), then each 
                    Right (other than Rights owned by an Acquiring Person or 
                    its affiliates) will entitle the holder thereof to 
                    purchase, for the Exercise Price, a number of shares of 
                    the Company's Common Stock having a then current market 
                    value of twice the Exercise Price.

FLIP-OVER:          If, after an Acquiring Person obtains 15% or more of the 
                    Company's Common Stock, (a) the Company merges into 
                    another entity, (b) an acquiring entity merges into the 
                    Company or (c) the Company sells more than 50% of the 
                    Company's assets or earning 

<PAGE>

                    power, then each Right (other than Rights owned by an 
                    Acquiring Person or its affiliates) will entitle the holder 
                    thereof to purchase, for the Exercise Price, a number of 
                    shares of Common Stock of the person engaging in the 
                    transaction having a then current market value of twice the 
                    Exercise Price (unless the transaction satisfies certain 
                    conditions and is consummated with a person who acquired 
                    shares pursuant to a Permitted Offer, in which case the 
                    Rights will expire).

EXCHANGE PROVISION: At any time after the date an Acquiring Person obtains 15%
                    or  more of the Company's Common Stock and prior to the
                    acquisition by the Acquiring Person of 50% of the
                    outstanding Common Stock, a majority of the Board of
                    Directors and a majority of the Continuing Directors of the
                    Company may exchange the Rights (other than Rights
                    owned by the Acquiring Person or its affiliates), in whole
                    or in part, for shares of Common Stock of the Company at
                    an exchange ratio of one share of Common Stock per Right
                    (subject to adjustment).

REDEMPTION OF       Rights will be redeemable at the Company's option for $0.01 
THE RIGHTS:         per Right at any time on or prior to the tenth day (or such
                    later date as may be determined by a majority of the 
                    Continuing Directors) after public announcement that a 
                    Person has acquired beneficial ownership of 15% or more 
                    of the Company's Common Stock (the "Shares Acquisition 
                    Date").

EXPIRATION OF       The Rights expire on the earliest of (a) March 14, 2007
THE RIGHTS:         (b) exchange or redemption of the Rights as described above,
                    or (c) consummation of a merger, consolidation or asset sale
                    resulting in expiration of the Rights as described above.   

AMENDMENT OF        The terms of the Rights and the Rights Agreement may be     
TERMS OF RIGHTS:    amended in any respect without the consent of the Rights    
                    holders on or prior to the Distribution Date; thereafter, 
                    the terms of the Rights and the Rights Agreement may be  
                    amended without the consent of the Rights holders in order
                    to cure any ambiguities or to make changes which do not   
                    adversely affect the interests of Rights holders (other than
                    the Acquiring Person).                                      

VOTING RIGHTS:      Rights will not have any voting rights.

ANTI-DILUTION       Rights will have the benefit of certain customary anti-
                    dilution provisions.

TAXES:              The Rights distribution should not be taxable for federal 
                    income tax purposes.  However, following an event which 
                    renders the Rights exercisable or upon redemption of the 
                    Rights, stockholders may recognize taxable income. 

                                     -2-
