     SECTION 4. Certain Covenants of the Company.

          (a)  The Company covenants that it will at all times reserve and keep
available out of its authorized Common Stock, solely for the purpose of issue
upon exercise of the Warrants, such number of shares of Common Stock as shall
then be issuable upon the exercise of all outstanding Warrants. The Company
covenants that all shares of Common Stock which shall be issuable upon exercise
of the Warrants and payment of the Purchase Price shall, at the tune of
delivery, be duly and validly issued, fully paid, nonassessable and free from
all taxes, liens and charges with respect to the issued thereof (other than
those which the Company shall promptly pay or discharge).

          (b)  The Company will use reasonable efforts to obtain appropriate
approvals or registrations under state "blue sky" securities laws with respect
to the exercise of the Warrants: provided, however, that the Company shall not
be obligated to file any general consent to service of process or qualify as a
foreign corporation in any jurisdiction. With respect to any such securities
laws, however, Warrants may not be exercised by, or shares of Common Stock
issued to, any Registered Holder in any State in which such exercise would be
unlawful.

          (c)  The Company shall pay all documentary, stamp or similar taxes and
other governmental charges that may be imposed with respect to the issuance of
Warrants, or the issuance, or delivery of any shares upon exercise of the
Warrants, provided, however, that if the shares of Common Stock are to be
delivered in a name other than the name of the Registered Holder of the Warrant
being exercise, then no such delivery shall be made unless the person requesting
the same has paid to the Company the amount of transfer taxes or charges
incident thereto, if any.

          (d)  The Company will take such action as any Registered Holder may
reasonable request, all to the extent required from time to time to facilitate
any sale or disposition by any such holder of the Warrants or Warrant Shares
without registration under the Act and/or any applicable state securities laws
within the limitation of the exemptions provided by any rule or regulation
thereunder, including, without limitation, Rule 144 under the Act (but excluding
Rule 144A thereunder). In addition, the Company will cooperate with each
Registered Holder in supplying such information as may be necessary to complete
and file any information reporting forms presently or thereafter required by any
regulatory authority; including, without limitation, the
<PAGE>

Securities and Exchange Commission, as a condition to exemption from the Act
and/or any applicable state securities law for the sale or other disposition of
any Warrant or any Warrant Shares.

          (e)  The Company shall indemnify, save and hold harmless the
Registered Holder and the holder of any Warrant Shares from and against any and
all liability, loss, costs, damage, reasonable attorneys' and accountants' fees
and expenses, court costs and all other out-of-pocket expenses incurred by such
holder in connection with preserving, exercising and/or enforcing any of the
terms hereof.

     SECTION 5. Transfer and Exchange of Warrant.

         (a)  Upon surrender for registration of transfer or exchange of this
Warrant at the Corporate Office, the Company shall execute and deliver in the
name of the designated transferee or transferees one or more new Warrants
representing the right to purchase at the Purchase Price a like aggregate number
of Warrant Shares. At the option of the holder hereof, this Warrant may be
exchanged for the other Warrants representing the right to purchase a like
aggregate number of Warrant Shares upon surrender of this Warrant at such
office. Whenever this Warrant is so surrendered for exchange, the Company shall
execute and deliver the Warrants which the holder making the exchange is
entitled to receive, provided, that Warrant Shares issuable pursuant to the
exchanged Warrants shall be issuable in an amount representing a whole number of
Warrant Shares. Every Warrant presented or surrendered for registration of
transfer or exchange shall be accompanied by an Assignment in the form attached
hereto duly executed by the holder thereof or its attorney duly authorized in
writing. All Warrants issued upon any registration of transfer or exchange of
other Warrants shall be the valid obligations of the Company, evidencing the
same rights, and entitled to the same benefits, as the Warrants surrendered upon
such registration of transfer or exchange. If any Warrant is to be issued in the
name or names of anyone other than the Registered Holder, then, if required by
the Company, the Registered Holder thereof shall deliver with such Warrant an
opinion of counsel to the effect that the sale, transfer, or assignment of the
Warrant Shares to be transferred or exchanged is exempt form the requirements of
the Act, which opinion shall be addressed to the Company, provided at the
expense of the Registered Holder of the Warrant to be transferred or exchanged
and provided by counsel reasonable satisfactory to the Company and in of the
form and substance reasonably satisfactory to the Company.

          (b)  the Company shall keep at its office books in which it shall
register the Warrants in accordance with its practice (the "Warrant Register").
The Company shall not at any time close the Warrant Register so as to result in
preventing or delaying the exercise or transfer of this Warrant.

          (c)  The Company may require payment by such holder of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection therewith.

          (d)  All Warrants surrendered for exercise, transfer, or for exchange
in case of mutilated Warrants, shall be promptly canceled by the Company and
thereafter retained by the Company until the Warrant Expiration Date, or such
other time as the Company shall determine solely with its discretion.

     SECTION 6.  Loss or Mutilation.  Upon receipt by the Company of
<PAGE>

evidence satisfactory to them of the ownership of and loss, theft, destruction
or mutilation of any Warrant and (in case of loss, theft or destruction) of
indemnity satisfactory to them, and (in case of loss, theft or destruction) upon
surrender and cancellation thereof, the Company shall execute and deliver to the
Registered Holder in lieu thereof a new Warrant or like tenor representing an
equal aggregate number of Warrants. Applicants for a substitute Warrant shall
comply with such other reasonable regulations and pay such other reasonable
charges as the Company may prescribe or require.

     SECTION 7.  Adjustment of Exercise Price and Number of Shares of Common
Stock or Warrants.

         (a)  Adjustment for Dividends in Other Stock, Property, etc.;
Reclassification, etc. In case at any time or from time to time, the holders of
Common Stock (or Other Securities) shall have received, or (on or after the
record date fixed for the determination of shareholders eligible to receive)
shall have become entitled to receive, without payment therefor.

              (i)  other or additional stock or other securities or property
     (other than cash) by way of dividend, or

             (ii)  any cash (excluding cash dividends payable solely out of
      earnings or earned surplus of the Company), or

            (iii)  other or additional stock or other securities or property
     (including cash) by way of spin-off, split-up, reclassification
     recapitalization, combination of shares or similar corporate rearrangement.

other than additional shares of Common Stock (or Other Securities) issued as a
stock dividend or in a stock-split (adjustments in respect of which are provided
for in subsection 7(c)(i), then and in each such case the holder of this
Warrant, on the exercise hereof, shall be entitled to receive the amount of
stock and other securities and property (including cash in the cases referred to
in subdivisions (ii) and (iii) of this section 7(a) which such holder would hold
on the date of such exercise if on the date hereof he had been the holder of
record of the finally determined number of Warrant Shares subject to this
Warrant and had thereafter, during the period from the date hereof to and
including the date of such exercise, retained such shares and all such other or
additional stock and other securities and property (including cash in the cases
referred to in subdivisions (ii) and (iii) of this section 7(a) receivable by
him as aforesaid during such period giving effect to all adjustments called for
during such period by sections 7(b) and 7(c).

           (b)  Adjustment for Reorganization, Consolidation, Merger, etc.

               (i)  In case at any time or from time to time, the Company shall
at any time consolidate with or merge into another corporation, the holder
hereof will thereafter receive, upon the exercise hereof, the securities or
property to which a holder of the number of share of Common Stock then
deliverable upon the exercise hereof would have been entitled upon such
consolidation or merger, and the Company shall take such steps in connection
with such consolidation or merger as may be necessary to assure that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to any securities or property thereafter deliverable upon the
exercise of the Warrant. A sale of all or substantially all of the assets
<PAGE>

of the Company for a consideration (apart from the assumption of obligations)
consisting primarily of securities shall be deemed a consolidation or merger for
the foregoing purposes.

               (ii)  In the event of any dissolution of the Company following
the transfer of all or substantially all of its properties or assets, the
Company, prior to such dissolution, shall at its expense deliver or cause to be
delivered the stock and other securities and property (including cash, where
applicable) receivable by the holder of this Warrant after the effective date of
such dissolution pursuant to this Section 7(b) to the Registered Holder.

               (iii)  Upon any reorganization, consolidation, merger or transfer
(and any dissolution following any transfer) referred to in this Section 7(b),
this Warrant shall continue in full force and effect and the terms hereof shall
be applicable to the share of stock and other securities and property receivable
upon the exercise of this Warrant after the consummation of such reorganization,
consolidation or merger or the effective date of dissolution following any such
transfer, as the case may be, and shall be binding upon the issuer of any such
stock or other securities, including, in the case of any such transfer, the
person acquiring all or substantially all of the properties or assets of the
Company.

          (c)  Adjustment for Stock Splits, Etc.

              (i)  Stock Splits, Etc. In the event that the Company shall (i)
issue additional shares of the Common Stock as a dividend or other distribution
on outstanding Common Stock, (ii) subdivide its outstanding shares of Common
Stock, or (iii) combine its outstanding share of the Common Stock into a smaller
number of shares of the Common Stock, then, in each such event, the Purchase
Price shall, simultaneously with the happening of such event, be adjusted by
multiplying the then Purchase Price by a fraction, the numerator of which shall
be the number of shares of Common Stock outstanding immediately prior to such
event and the denominator of which shall be the number of shares of Common Stock
outstanding immediately after such event, and the product so obtained shall
thereafter be the Purchase Price then in effect. The Purchase Price, as so
adjusted, shall be readjusted in the same manner upon the happening of any
successive event or events described herein in this subsection 7(c)(i). The
holder of this Warrant shall thereafter, on the exercise hereof, be entitled to
receive that number of shares of Common Stock determined by multiplying the
number of shares of Common Stock which would otherwise (but for the provisions
of this subsection 7(c)(i) be issuable on such exercise by a fraction of which
(i) the numerator is the Purchase Price which would otherwise(but for the
provisions of this subsection 7(c)(i) be in effect, and(ii) the denominator is
the Purchase Price in effect on the date of such exercise.

         (d)  Certificate as to Adjustments. In each case of any adjustment or
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the Warrants, the Company at its expense will promptly cause its
Chief Financial Officer or independent certified public accountants of
recognized standing selected by the Company to compute such adjustment or
readjustment in accordance with the terms of the Warrants and prepare a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based, including a
statement of (i) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold, (ii)
<PAGE>

the number of shares of common stock to be received upon exercise of this
Warrant, in effect immediately prior to such issue or sale and as adjusted and
readjusted as provided in this Warrant. The Company will forthwith mail a copy
of each such certificate to each holder of a Warrant, and will, on the written
request at any time of any holder of a Warrant, furnish to such holder a like
certificate setting forth the Purchase Price at the time in effect and showing
how it was calculated.

     SECTION 8.  Fractional Warrants and Fractional Shares.

          (a)  If the number of shares of Common Stock purchasable upon the
exercise of each Warrant is adjusted pursuant to Section 7 hereof, the Company
shall nevertheless not be required to issue fractions of shares, upon exercise
of the Warrants or otherwise, or to distribute certificates that evidence
fractional shares. With respect to any fraction of a share called for upon any
exercise hereof, the Company shall pay to the Registered Holder an amount in
cash equal to such fraction multiplied by the current market value of such
fractional share, determined as follows:

               (i)    If the Common Stock is listed on a national securities
exchange or admitted to unlisted trading privileges on such exchange or listed
for trading on the NASDAQ National Market ("NMS"), the current value shall be
the last reported sale price of the Common Stock on such exchange on the last
business day prior to the Exercise Date or if no closing sale price is quoted,
the average of the closing bid and asked prices for such day on such exchange or
system; or

                (ii)   If the Common Stock is listed in the over-the-counter
market (other than on NMS) or admitted to unlisted trading privileges, the
current value shall be the mean of the last reported bid and asked prices
reported by the National Quotation Bureau, Inc. on the last business day prior
to the Exercise Date; or

                 (iii)  If the Common Stock is not so listed or admitted to
unlisted trading privileges and bid and asked prices are not so reported, the
current value shall be the Purchase Price.

     SECTION 9.  Warrantholder Not Deemed Stockholder. No Holder of Warrants
shall, as such, be entitled to vote or to receive dividends or be deemed the
holder of Common Stock that may at any time be issuable upon exercise of such
Warrants for any purpose whatsoever, nor shall anything contained herein be
construed to confer upon the holder of Warrants, 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 (whether upon any recapitalization,
issue or reclassification of stock, change of par value or change of stock to no
par value, consolidation, merger or conveyance or otherwise), or to receive
notice of meetings, or to receive dividends or subscription rights, until such
holder shall have exercised such Warrants and been issued shares of Common Stock
in accordance with the provisions hereof.

     10.   Registration Rights.

          (a)  Demand Registration Right. The Company covenants and agrees with
the Registered Holder and any subsequent Registered Holders of the Warrants
and/or Warrants Shares that, on one occasion, within 60 days after receipt of a
written request from Registered Holders of more than 50% in
<PAGE>

interest of the aggregate of Warrants and/or Warrant Shares issued pursuant
hereto, the Company shall, on one occasion, file a registration statement (and
use its best efforts to cause such registration statement to become effective
under the Act at the Company's expense) with respect to the offering and sale or
other disposition of the Warrant Shares (the "Offered Warrant Shares"). The
Company shall not be obligated to file and have declared effective a
registration statement with respect to the Offered Warrant Shares on more than
one occasion.

     The Company may defer the filing of a registration statement for up to 90
days after the request for registration is made if the Board of Directors
determines in good faith that such registration or post-effective amendment
would adversely affect or otherwise interfere with a proposed or pending
transaction by the Company, including without limitation a material financing or
a corporate reorganization, or during any period of time in which the Company is
in possession of material inside information concerning the Company or its
securities, which information the Company determines in good faith is not ripe
for discharge.

     The Company shall not honor any request to register Warrant Shares pursuant
to this Section received later than the Warrant Expiration Date. The Company
shall not be required (i) to maintain the effectiveness of the registration
statement beyond the earlier to occur of 120 days after the effective date of
the registration statement or the date on which all of the Offered Warrant
Shares have been sold (the "Termination Date"); provided, however, that if at
the Termination Date the Offered Warrant Shares are covered by a registration
statement which also covers other securities and which is required to remain in
effect beyond the Termination Date, the Company shall maintain in effect such
registration statement as it relates to Offered Warrant Shares for so long as
such registration statement (or any substitute registration statement) remains
or is required to remain in effect for any such other securities. All expenses
of registration pursuant to this subsection 10(a) shall be borne by the Company.

     The Company shall be obligated pursuant to this Section to include in the
registration statement Warrant Shares that have not yet been purchased by a
Registered Holder of Warrants so long as such Registered Holder of Warrants
submits an undertaking to the Company that such Registered Holder intends to
exercise Warrants representing the number of Warrant Shares to be included in
such registration statement prior to the consummation of the public offering
with respect to such Warrant Shares. In addition, such Registered Holder of
Warrants is permitted to pay the Company the Warrant Price for such Warrant
Shares upon the consummation of the public offering with respect to such Warrant
Shares.

      (b)       Piggy-back Registration Rights. The Company covenants and agrees
with the Registered Holders and any subsequent Registered Holders of the
Warrants and/or Warrant Shares that in the event the Company proposes to file a
registration statement under the Act with respect to any class of security
(other than in connection with an exchange offer, an non-cash offer or a
registration statement on Form S-8 or Form S-4 or other unsuitable registration
statement form) which becomes effective then the Company shall in each case give
written notice of such proposed filing to the Registered Holders of Warrants and
Warrant Shares at least 30 days before the proposed filing date and such notice
shall offer to such Registered Holders the opportunity to include in such
registration statement such number of Warrant Shares as they may request,
unless, in the opinion of counsel to
<PAGE>

the Company reasonably acceptable to any such Registered Holder of Warrants or
Warrant Shares who wishes to have Warrant Shares included in such registration
statement, registration under the Act is not required for the transfer of such
Warrants and/or Warrant Shares in manner proposed by such Registered Holders.
The Company shall not honor any such request to register any such Warrant Shares
if the request is received later than the Warrant Expiration Date, and the
Company shall not be required to honor any request (a) to register any such
Warrant Shares if the Company is not notified in writing of any such request
pursuant to this Section within at least 20 days after the Company has given
notice to the Registered Holders of the filing, or (b) to register Warrant
Shares that represent in the aggregate fewer than 25% of the aggregate number of
Warrant Shares. The Company shall permit, or shall cause the managing
underwriter of a proposed offering to permit, the Registered Holders of Warrant
Shares requested to be included in the registration (the "Piggy-back Shares") to
include such Piggy-back Shares in the proposed offering on the same terms and
conditions as applicable to securities of the Company included therein or as
applicable to securities of any person other than the Company and the Registered
Holders of Piggy-back Shares if the securities of any such person are included
therein. Notwithstanding the foregoing, if any such managing underwriter shall
advise the Company in writing that it believes that the distribution of all or a
portion of the Piggy-back Shares requested to be included in the registration
statement concurrently with the securities being registered by the Company would
materially adversely affect the distribution of such securities by the Company
for its own account, then the number of shares to be offered for the account of
all persons (other than the Company or such other persons on whose behalf the
underwritten offering was initiated) participating in such registration shall be
reduced or limited (to zero if necessary) pro rata in proportion to the extent
necessary to reduce the total number of shares requested to be included in such
offering to the number of shares, if any, recommended by such managing
underwriter or underwriters. All expenses of the piggy-back registration
pursuant to this section 10(b) shall be borne by the Company, except that
underwriting commissions and expenses attributable to the Piggy-back Shares and
fees and disbursements of counsel (if any) to the Registered Holders requesting
that such Piggy-back Shares be offered will be borne by such Registered Holders.

     The Company shall be obligated pursuant to this subsection 10(b) to include
in the Piggy-back Offering, Warrant Shares that have not yet been purchased by a
Registered Holder of Warrants so long as such Registered Holder of Warrants
submits an undertaking to the Company that such Registered Holder intends to
exercise Warrants representing the number of Warrant Shares to be included in
such Piggy-back Offering prior to the consummation of such Piggy-back Offering.
In addition, such Registered Holder of Warrants is permitted to pay the Company
the Warrant Price for such Warrant Shares upon the consummation of the Piggy-
back Offering.

     If the Company decides not to proceed with a Piggy-back Offering, the
Company has no obligation to proceed with the offering of the Piggy-back Shares.

               (c)  In connection with the registration of Warrant Shares in
accordance with this Section, the Company agrees to:

                    (i)  Use its best efforts to register or qualify the Warrant
Shares for offer or sale under the state securities or Blue Sky
<PAGE>

laws of such states which the Registered Holders of such Warrant Shares shall
designate, until the dates specified in subsections 10(a) and 10(b) above in
connection with registration under the Act; provided, however, that in no event
shall the Company be obligated to qualify to do business in any jurisdiction
where it is not now so qualified or to take any action which would subject it to
general service of process in any jurisdiction where it is not now so subject or
to register or get a license as a broker or dealer in securities in any
jurisdiction where it is not so registered or licensed.

                    (ii)   (A)   in the event of any registration with respect
to any Warrant Shares pursuant to this Section, the Company will indemnify and
hold harmless any Registered Holder whose Warrant Shares are being so registered
and each person, if any, who controls such Registered Holder within the meaning
of the Act, against any losses, claims, damages or liabilities, joint or
several, to which such Registered Holder or such controlling person may be
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained, on
the effective date thereof, in any such registration statement, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading; and will reimburse each such Registered
Holder and each such controlling person for any legal or other expenses
reasonably incurred by such Registered Holder or such controlling person in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
such case to the extent that any such loss, claim, damage or liability arises
out of or is based upon any untrue statement or alleged untrue statement or
omission or alleged omission made in any such registration statement, any
preliminary prospectus of final prospectus, or any amendment or supplement
thereto, in reliance upon and in conformity with written information furnished
by such Registered Holder expressly for use in the preparation thereof. The
Company will not be liable to a claimant to the extent of any misstatement
corrected or remedied in any amended prospectus if the Company timely delivers a
copy of such amended prospectus to such indemnified person and such indemnified
person does not timely furnish such amended prospectus to such claimant. The
Company shall not be required to indemnify any Registered Holder or controlling
person for any payment made to any claimant in settlement of any suit or claim
unless such payment is approved by the Company.

                           (B)   Each such Registered Holder of Warrants and/or
Warrant Shares will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed any such registration statement,
and each person, if any, who controls the Company within the meaning of the Act,
against any losses, claims, damages or liabilities to which the Company, or any
such director, officer or controlling person may become subject under the Act,
or otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue or alleged untrue
statement of any material fact contained in any such registration statement, any
preliminary prospectus or final prospectus, or any amendment or supplement
thereto,
<PAGE>

or arise out of or are based upon the omission or the alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in any such registration statement, any preliminary
prospectus or final prospectus, or any amendment or supplement thereto, in
reliance upon and in conformity with written information furnished by such
Registered Holder expressly for use in the preparation thereof; and will
reimburse any legal or other expenses reasonably incurred by the Company, or any
such director, officer or controlling person in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this subparagraph 10(c)(ii)(B) shall
not apply to amounts paid to any claimant in settlement of any suit or claim
unless such payment is first approved by such Registered Holder.

                           (C)   In order to provide for just and equitable
contribution in any action in which a claim for indemnification is made pursuant
to this subsection 10(c)(ii)(C) but is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this subsection 10(c)(ii)(C) provides for indemnification in such case, all the
parties hereto shall contribute to the aggregate losses, claims, damages or
liabilities ("Damages") to which they may be subject (after contribution from
others) in such proportion as is appropriate to reflect the relative fault of
the Company on the one hand and the Registered Holders on the other hand in
connection with the statements or omissions that resulted in such Damages, as
well as any other relevant equitable considerations. The relative fault of the
Company on the one hand and of the Registered Holders on the other hand shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or by the
Registered Holders and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission so
that each Registered Holder whose Warrant Shares are being registered is
responsible pro rata for the portion represented by the public offering price
received by such Registered Holder from the sale of such Registered Holder's
Warrant Shares, and the Company is responsible for the remaining portion;
provided, however, that (i) no Registered Holder shall be required to contribute
any amount in excess of the public offering price received by such Registered
Holder from the sale of such Registered Holder's Warrant Shares and (ii) no
person guilty of a fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who is not
guilty of such fraudulent misrepresentation. This subsection 10(c)(ii)(C) shall
not be operative as to any Registered Holder of Warrant Shares to the extent
that the Company has received indemnity under this subsection 10(c)(ii)(C).

               (d)  Pursuant to that certain Registration Rights Agreement dated
as of December 29, 1995, between the Company, and Fidelity Galileo Fund, L.P.
and Fidelity Copernicus Fund, L.P. (collectively, "Fidelity"), the Company is
obligated to file a registration statement registering 500,000 shares of Common
Stock owned by Fidelity by March 15, 1996 (the
<PAGE>

"Fidelity Registration"). The Registered Holder(s) hereby agrees that the
registration of Warrant Shares at the same time as the Fidelity Registration,
provided such registration becomes effective on the same terms as Section 2(a)
of the Registration Rights Agreement (except that the Target Filing Date for
purposes of this Warrant shall be April 30, 1996 and the Target Effective Date
shall mean the date 90 days after April 30, 1996), shall satisfy and constitute
exercise of the demand registration right set forth in subsection 10(a) herein.

     SECTION 11.  Rights of Action. All rights of action with respect to this
Warrant are vested in the Registered Holder of the Warrants, and the Registered
Holder of a Warrant, without consent of the holder of any other Warrant, may, on
his own behalf and for his own benefit, enforce against the Company his right to
exercise his Warrants for the purchase of shares of Common Stock in the manner
provided in this Warrant.

     SECTION 12.  Agreement of Warrantholder.  Every holder of a Warrant, by his
acceptance thereof, consents and agrees with the Company that the Company may
deem and treat the person in whose name the Warrant is registered as the holder
and as the absolute, true and lawful owner of the Warrants represented thereby
for all purposes, and the Company shall not be affected by any notice or
knowledge to the contrary.

     SECTION 13.  Gender, Singular and Plural.  When the context and
construction so require, all words used in the singular herein shall be deemed
to have been used in the plural and the masculine shall include the feminine and
neuter and vice versa.

     SECTION 14.  Governing Law.  This Warrant shall be governed by and
construed in accordance with the laws of the State of California, without
reference to principles of conflict of laws.

     SECTION 15.  Notices.  All notices, requests, consents and other
communications hereunder shall be in writing and shall be deemed to have been
made when delivered or mailed first class registered or certified mail, postage
prepaid, as follows: if to the Registered Holder of a Warrant, at the address of
such holder as shown on the registry books maintained by the Company; if to the
Company, at 404 E. Huntington Drive, Monrovia, California 91016, Attention:
Chairman or President.

     SECTION 16.  Binding Effect.  This Warrant shall be binding upon and inure
to the benefit of the Company (and its respective successors and assigns) and
the holders from time to time of Warrants. Nothing in this Warrant is intended
or shall be construed to confer upon any other person any right, remedy or
claim, in equity or at law, or to impose upon any other person and duty,
liability or obligation.

     SECTION 17.  Termination.  This Warrant shall terminate at the close of
business on the Warrant Expiration Date.

     SECTION 18.  Amendment.  Any amendment, supplement or modification of or to
any provision of this Warrant, any waiver of any provision of this Warrant and
any consent to any departure by any party from the terms of any provision of
this Warrant, shall be effective (i) only if it is
<PAGE>

made or given in writing and signed by the Company and by the beneficial owners
of a majority of the Warrant Shares (assuming exercise of all outstanding
Warrants), and (ii) only in the specific instance and for the specific purpose
for which made or given.

     SECTION 19.  Remedies.  The Company stipulates that the remedies at law of
the holders of the Warrants and of Warrant Shares in the event of any default or
threatened default by the Company in the performance of or compliance with any
of the terms of the Warrants are not and will not be adequate and that, to the
fullest extent permitted by law, such terms may be specifically enforced by a
decree for the specific performance of any agreement contained herein or therein
or by an injunction against a violation of any of the terms hereof or thereof,
or otherwise.

     SECTION 20.  Modification and Severability. If, in any action before any
court or agency legally empowered to enforce any provision contained herein, any
provision hereof is found to be unenforceable, then such provision shall be
deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is unenforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

     IN WITNESS WHEREOF, the undersigned individual has signed this Warrant on
behalf of the Company as of the date first above written.
