                        DURATION AND EXERCISE OF WARRANT

     SECTION 2.01: DURATION OF WARRANT. Subject to the terms contained
herein, this Warrant may be exercised at any time after June 23, 1999, and
before 5:00 P.M. New York time, on the Expiration Date (or, if such day is not a
Business Day, at or before 5:00 P.M. New York time, on the next following
Business Day). If this Warrant is not exercised at or before 5:00 P.M., New York
time, on the Expiration Date, it shall become void, and all rights hereunder
shall thereupon cease.

     SECTION 2.02:  EXERCISE OF WARRANT.

          (a) The Warrantholder may exercise this Warrant, in whole or in part,
upon surrender of this Warrant with the Subscription Form hereon duly executed,
to the Company at its corporate office in San Diego, California, together with
the full Exercise Price for each share of Common Stock to be purchased in lawful
money of the United States, or by certified check, bank draft or postal or
express money order payable in United States Dollars to the order of the Company
and upon compliance with and subject to the conditions set forth herein.

          (b) Upon receipt of this Warrant with the Subscription Form duly
executed and accompanied by payment of the aggregate Exercise Price for the
shares of Common Stock for which this Warrant is then being exercised, the
Company will cause to be issued certificates for the total number of whole
shares of Common Stock for which this Warrant is being exercised in such
denominations as are required for delivery to the Warrantholder, and the Company
shall thereupon deliver such certificates to the Warrantholder. If at the time
this Warrant is exercised, a registration statement is not in effect to register
under the Securities Act the Warrant Shares issuable upon exercise of this
Warrant, the Company may require the Warrantholder to make such investment
intent representations, and may place such legends on certificates representing
the Warrant Shares, as may be reasonably required in the opinion of counsel to
the Company to permit the Warrant Shares to be issued without such registration.

          (c) In case the Warrantholder shall exercise this Warrant with respect
to less than all of the shares of Common Stock that may be purchased under this
Warrant, the Company will execute a new warrant certificate in the form of this
Warrant for the balance of the shares of Common Stock that may be purchased upon
exercise of this Warrant and deliver such new warrant certificate to the
Warrantholder.

          (d) The Company covenants and agrees that it will pay when due and
payable any and all taxes which may be payable in respect of the issue of this
Warrant or in respect of the issue of any Warrant Shares. The Company shall not,
however, be required to pay any tax imposed on income or gross receipts or any
tax which may be payable in respect of any transfer involved in the issuance or
delivery of this Warrant or of Warrant Shares in a name other than that of the
Warrantholder at the time of surrender and, until the payment of such tax, shall
not be required to issue such Warrant Shares.

                                   ARTICLE III
                      ADJUSTMENT OF SHARES OF COMMON STOCK
                        PURCHASABLE AND OF EXERCISE PRICE

The Exercise Price and the number and kind of Warrant Shares shall be subject to
adjustment from time to time upon the happening of certain events as provided in
this Article III.

     SECTION 3.01:  MECHANICAL ADJUSTMENTS.

          (a) If at any time prior to the full exercise of this Warrant, the
Company shall (i) pay a dividend or make a distribution on its shares of Common
Stock in shares of Common Stock (other than cash dividends or distributions out
of earnings); (ii) subdivide, reclassify or recapitalize its outstanding Common
Stock into a greater number of shares; or (iii) combine, reclassify or
recapitalize its outstanding Common Stock into a smaller number of shares, the
Exercise Price in effect at the time of the record date of such subdivision,
combination, reclassification or recapitalization shall be proportionately
adjusted so that the Warrantholder shall be entitled to receive the aggregate
number and kind of shares which, if this Warrant had been exercised in full
immediately prior to such time, he would have owned upon such exercise and been
entitled to receive upon such dividend, subdivision, combination,
reclassification or recapitalization. Such adjustment shall be made successively
whenever any event listed in this paragraph 3.01(a) shall occur.

          (b) In case the Company shall hereafter fix a record date for making a
distribution to the holders of Common Stock of assets or evidences of its
indebtedness (excluding cash dividends or distributions out of earnings and
dividends or distributions referred to in paragraph (a) of this Section 3.01) or
Common Stock subscription rights, options or warrants for Common Stock or Common
Stock Equivalents, then in each such case the Exercise Price in effect after
such record date shall be adjusted to the price determined by multiplying the
Exercise Price in effect immediately prior thereto by a fraction, the numerator
of which shall be the total number of shares of Common Stock outstanding at such
time multiplied by the current market price per share of Common Stock (as
defined in paragraph (d) of this Section 3.01), less the fair market value (as
determined by the Company's Board of Directors) of said assets or evidences of
indebtedness so distributed or of such Common Stock subscription rights, option
and warrants or of such Common Stock Equivalents, and the denominator of which
shall be the total number of shares of Common Stock outstanding at such time
multiplied by such current market price per share of Common Stock. Such
adjustment shall be made successively whenever the record date for such a
distribution is fixed and shall become effective immediately after such record
date.

          (c) Whenever the Exercise Price payable upon exercise of each Warrant
is adjusted pursuant to paragraphs (a) or (b) of this Section 3.01, the Warrant
Shares shall simultaneously be adjusted by multiplying the number of Warrant
Shares then issuable upon exercise of each Warrant by the Exercise Price in
effect on the date thereof and dividing the product so obtained by the Exercise
Price as adjusted.

          (d) For the purpose of any computation under this Section 3.01, the
current market price per share of Common Stock at any date shall be deemed to be
the average of the daily closing price for 30 consecutive Business Days
commencing 45 Business Days before such date. The closing price for each day
shall be the last sale price regular way or, in case no such reported sales
takes place on such day, the average of the last reported bid and asked prices
regular way, in either case on the principal national securities exchange on
which the Common Stock is admitted to trading or listed, or if not listed or
admitted to trading on such exchange, the representative closing bid price as
reported by NASDAQ, or other similar organization if NASDAQ is no longer
reporting such information, or if not so available, the fair market price as
determined in good faith by the Board of Directors.

          (e) No adjustment in the Exercise Price shall be required unless such
adjustment would require an increase or decrease of at least twenty-five cents
($.25) in such price; provided, however, that any adjustments which by reason of
this paragraph (e) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this
Section 3.01 shall be made to the nearest cent or to the nearest one-hundredth
of a share, as the case may be. Notwithstanding anything in this Section 3.01 to
the contrary, the Exercise Price shall not be reduced to less than the then
existing par value of the Common Stock as a result of any adjustment made
hereunder.

          (f) In the event that at any time, as a result of any adjustment made
pursuant to paragraph (a) of this Section 3.01, the Warrantholder thereafter
shall become entitled to receive any shares of the Company, other than Common
Stock, thereafter the number of such other shares so receivable upon exercise of
any Warrant 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
Common Stock contained in paragraphs (a) to (e), inclusive, of this Section
3.01.

     SECTION 3.02: NOTICE OF ADJUSTMENT. Whenever the number of Warrant
Shares or the Exercise Price is adjusted as herein provided, the Company shall
prepare and deliver to the Warrantholder a certificate signed by its President,
any Vice President, Treasurer or Secretary, setting forth the adjusted number of
shares purchasable upon the exercise of this Warrant and the Exercise Price of
such shares after such adjustment, setting forth a brief statement of the facts
requiring such adjustment and setting forth the computation by which adjustment
was made.

     SECTION 3.03: NO ADJUSTMENT FOR DIVIDENDS. No adjustment in respect of
any cash dividends shall be made during the term of this Warrant or upon the
exercise of this Warrant.

     SECTION 3.04: PRESERVATION OF PURCHASE RIGHTS IN CERTAIN TRANSACTIONS.
In case of any consolidation of the Company with or merger of the Company into
another corporation or in case of any sale or conveyance to another corporation
of the property of the Company as an entirety or substantially as an entirety,
the Company agrees that a condition of such transaction will be that the Company
or such successor or purchasing corporation, as the case may be, shall execute
with the Warrantholder an agreement granting the Warrantholder the right
thereafter, upon payment of the Exercise Price in effect immediately prior to
such action, to receive upon exercise of this Warrant the kind and amount of
shares and other securities and property which he would have owned or have been
entitled to receive after the happening of such consolidation, merger, sale or
conveyance had this Warrant been exercised immediately prior to such action.
Such agreement shall provide for adjustments, which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article
III. The provisions of this Section 3.04 shall similarly apply to successive
consolidations, mergers, sales, or conveyances.

     SECTION 3.05: FORM OF WARRANT AFTER ADJUSTMENTS. The form of this
Warrant need not be changed because of any adjustments in the Exercise Price or
the number or kind of the Warrant Shares, and Warrants theretofore or thereafter
issued may continue to express the same price and number and kind of shares as
are stated in this Warrant as initially issued.

                                   ARTICLE IV
              OTHER PROVISIONS RELATING TO RIGHTS OF WARRANTHOLDER

     SECTION 4.01: NO RIGHTS AS SHAREHOLDERS; NOTICE TO WARRANTHOLDERS. Nothing
contained in this Warrant shall be construed as conferring upon the
Warrantholder or his transferees the right to vote or to receive dividends or to
consent or to receive notice as shareholders in respect of any meeting of
shareholders for the election of directors of the Company or any other matter,
or any rights whatsoever as shareholders of the Company. If, however, at any
time prior to the expiration or exercise in full of the Warrants, any of the
following events shall occur:

          (a) the Company shall declare any dividend payable in any securities
upon its shares of Common Stock or make any distribution (other than a cash
dividend) to the holders of its shares of Common Stock; or

          (b) the Company shall offer to the holders of its shares of Common
Stock any additional shares of Common Stock or Common Stock Equivalents or any
right to subscribe thereto; or

          (c) a dissolution, liquidation or winding up of the Company (other
than in connection with a consolidation, merger, or sale of all or substantially
all of its property, assets, and business as an entirety) shall be proposed;

          then, in any one or more of said events, the Company shall give notice
of such event to the Warrantholder. Such giving of notice shall be initiated (i)
at least 25 days prior to the date fixed as a record date or the date of closing
the Company's Stock transfer books for the determination of the shareholders
entitled to such dividend, distribution, or subscription rights, or for the
determination of the shareholders entitled to vote on such proposed dissolution,
liquidation or winding up. Such notice shall specify such record date or the
date of closing the stock transfer books, as the case may be. Failure to provide
such notice shall not affect the validity of any action taken in connection with
such dividend, distribution or subscription rights, or proposed dissolution,
liquidation or winding up.

     SECTION 4.02: LOST, STOLEN, MUTILATED OR DESTROYED WARRANTS. If this
warrant certificate is lost, stolen, mutilated or destroyed, the Company may, on
such terms as to indemnity or otherwise as it may in its discretion impose
(which shall, in the case of a mutilated Warrant, include the surrender
thereof), issue a new warrant certificate of like denomination and tenor as, and
in substitution for this Warrant.

     SECTION 4.03: RESERVATION OF SHARES.

          (a) The Company covenants and agrees that at all times it shall
reserve and keep available for the exercise of this Warrant such number of
authorized shares of Common Stock as are sufficient to permit the exercise in
full of this Warrant.

          (b) The Company covenants that all shares of Common Stock issued on
exercise of this Warrant will be validly issued, fully paid, nonassessable and
free of pre-emptive rights.

     SECTION 4.04: NO FRACTIONAL SHARES. Anything contained herein to the
contrary notwithstanding, the Company shall not be required to issue any
fraction of a share in connection with the exercise of this Warrant, and in any
case where the Warrantholder would, except for the provisions of this Section
4.04, be entitled under the terms of this Warrant to receive a fraction of a
share upon the exercise of this Warrant, the Company shall, upon the exercise of
this Warrant and receipt of the Exercise Price, issue the number of whole shares
purchasable upon exercise of this Warrant. The Company shall be required to make
any cash or other adjustment in respect of such fraction of a share to which the
Warrantholder would otherwise be entitled.

                                    ARTICLE V
                           TREATMENT OF WARRANTHOLDER

     SECTION 5.01. Prior to due presentment for registration of transfer of this
Warrant, the Company may deem and treat the Warrantholder as the absolute owner
of this Warrant (notwithstanding any notation of ownership or other writing
hereon) for the purpose of any exercise hereof and for all other purposes and
the Company shall not be affected by any notice to the contrary.

                                   ARTICLE VI
                              TRANSFER RESTRICTIONS

     SECTION 6.01: RESTRICTIONS ON TRANSFER. This Warrant may be transferred, in
whole or in part, subject to the following restrictions. Neither this Warrant
nor the Registrable Securities received upon exercise of this Warrant shall be
transferable unless registered under the Securities Act or unless an exemption
from registration is available. Unless and until this Warrant or the Registrable
Securities are so registered, such securities and any certificate thereof shall
contain a legend on the face thereof, in form and substance satisfactory to
counsel for the Company, stating that the Warrant or Registrable Securities, as
the case may be, may not be sold, transferred or otherwise disposed of unless,
in the opinion of counsel satisfactory to the Company, which may be counsel to
the Company, the Warrant, or Registrable Securities may be transferred without
such registration. This Warrant and the Registrable Securities may also be
subject to restrictions on transferability under applicable state securities or
blue sky laws. Unless and until this Warrant or Registrable Securities, as the
case may be, are registered under the Securities Act, the holder of such
securities shall, if requested by the Company, provide to the Company an opinion
of counsel reasonably satisfactory to the Company, to the effect that (i) the
Warrant or Registrable Securities, as the case may be, may be transferred
without such registration and (ii) the transfer will not violate any applicable
state securities or blue sky laws. Any transfer of this Warrant permitted
hereunder shall be made by surrender of this Warrant to the Company with the
form of assignment annexed hereto properly completed and duly executed and
accompanied by (x) any necessary documentation required hereunder and (y) funds
sufficient to pay any transfer taxes applicable. Upon satisfaction of all
transfer conditions, the Company, without charge, shall execute and deliver a
new Warrant in the name of the transferee named in such transfer form, and this
Warrant promptly shall be canceled.

     SECTION 6.02: SPLIT-UP, COMBINATION, EXCHANGE AND TRANSFER OF WARRANTS.
Subject to and limited by the provisions of Section 6.01 hereof, this Warrant
may be split up, combined or exchanged for another Warrant or Warrants
containing the same terms to purchase a like aggregate number of shares of
Common Stock. If the Warrantholder desires to split up, combine or exchange this
Warrant, he shall make such request in writing delivered to the Company and
shall surrender to the Company this Warrant and any other Warrants to be so
split up, combined or exchanged. Upon any such surrender for a split-up,
combination, or exchange, the Company shall execute and deliver to the Person
entitled thereto a Warrant or Warrants, as the case may be, as so requested. The
Company shall not be required to effect any split-up, combination or exchange
which will result in the issuance of a Warrant entitling the Warrantholder to
purchase upon exercise a fraction of a share of Common Stock or a fractional
Warrant. The Company may require such Warrantholder to pay a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
split-up, combination or exchange of Warrants.

                                   ARTICLE VII
                  REGISTRATION UNDER THE SECURITIES ACT OF 1933

     SECTION 7.01: PIGGYBACK REGISTRATION.

          (a) RIGHT TO INCLUDE REGISTRABLE SECURITIES. If at any time after June
30, 1996, the Company proposes to register any class of debt or equity security
or any Common Stock Equivalent under the Securities Act on any form for the
general registration of securities under such Securities Act, whether or not for
its own account (other than a registration form relating to (i) a registration
of a stock option, stock purchase or compensation or incentive plan or stock
issued or issuable pursuant to any such plan, or a dividend investment plan;
(ii) a registration of stock proposed to be issued in exchange for securities or
assets of, or in connection with a merger or consolidation with, another
corporation; or (iii) a registration of stock proposed to be issued in exchange
for other securities of the Company) in a manner which would permit registration
of Registrable Securities for sale to the public under the Securities Act (a
"Piggyback Registration"), it will at such time give prompt written notice to
all Holders of Registrable Securities of its intention to do so and of such
Holders' rights under this Section 7.01. Upon the written request of any such
Holder made within 15 days after the receipt of any such notice (which request
shall specify the Registrable Securities intended to be disposed of by such
Holder and the intended method of disposition thereof), the Company will include
in the Registration Statement the Registrable Securities which the Company has
been so requested to register by the Holders thereof.

          (b) WITHDRAWAL OF PIGGYBACK REGISTRATION BY COMPANY. If, at any time
after giving written notice of its intention to register any securities but
prior to the effective date of the Registration Statement filed in connection
with such registration, the Company shall determine for any reason not to
register such securities, the Company may, at its election, give written notice
of such determination to each Holder and, thereupon shall be relieved of its
obligation to register any Registrable Securities in connection with such
registration. All best efforts obligations of the Company pursuant to Section
7.04 shall cease if the Company determines to terminate any registration where
Registrable Securities are being registered pursuant to this Section 7.01.

          (c) PIGGYBACK REGISTRATION OF UNDERWRITTEN PUBLIC OFFERINGS. If a
Piggyback Registration requested pursuant to this Section 7.01 involves an
underwritten offering, then, (i) all Holders requesting to be included in the
Company's registration must sell their Registrable Securities to the
underwriters selected by the Company on the same terms and conditions as apply
to other selling shareholders or the Company, if there are no selling
shareholders; and (ii) any Holder requesting to be included in such registration
may elect in writing, not later than five (5) Business Days prior to the
effectiveness of the Registration Statement filed in connection with such
registration, not to register such securities in connection with such
registration.

          (d) PAYMENT OF REGISTRATION EXPENSES FOR REGISTRATION. The Company
will pay all Registration Expenses in connection with each registration of
Registrable Securities requested pursuant to this Section 7.01, except for the
fees and disbursements of any counsel retained by the Holders of the Registrable
Securities being registered and such Holders' pro rata share of any filing fees
or other expenses directly and solely resulting from the inclusion of the
Registrable Securities in the Registration Statement, including underwriting
discounts and commissions.

          (e) PRIORITY IN PIGGYBACK REGISTRATION. If a registration pursuant to
this Section 7.01 involves an underwritten offering and the managing underwriter
advises the Company in writing that, in its opinion, the number or kind of
Registrable Securities requested to be included in such registration would have
a material adverse effect on such offering, including an adverse decrease in the
price at which such securities can be sold, then the amount or kind of
Registrable Securities to be offered for the accounts of Holders shall be
eliminated entirely or reduced pro rata as to all requesting Holders on the
basis of the relative number of Registrable Securities each such Holder has
requested to be included in such registration, to the extent necessary to reduce
the total amount or kind of securities to be included in such offering to the
amount recommended by such managing underwriter; provided, however, that no
securities may be offered in such registration for the account of persons other
than the Company by virtue of their also having "piggyback" registration rights,
or otherwise, unless the Registrable Securities requested to be included in such
registration are so included on a pro rata basis.

          (f) EXPIRATION OF PIGGYBACK REGISTRATION IN RIGHTS. The Piggyback
Registration rights granted to the Holders of Registrable Securities by this
Section 7.01 shall survive the exercise of the Warrant or the transactions or
events pursuant to which such Registrable Securities were issued, but all such
rights will terminate in all events two (2) years after exercise of this
Warrant.

     SECTION 7.02: BUY-OUTS OF REGISTRATION DEMAND. In lieu of carrying out
its obligations to effect the Piggyback Registration of Registrable Securities
pursuant to this Article VII, the Company may discharge such obligation by
offering to purchase and, if accepted, by purchasing such Registrable Securities
requested to be registered at 95% of the closing bid or sale price of the Common
Stock on the day the request or demand for Registration is made. If the offer to
purchase is accepted by the Holder, payment will be made by wire transfer or
certified check in U.S. dollars within ten (10) business days of receipt by the
Company of written acceptance by such Holder, accompanied by the stock
certificate representing such shares duly endorsed to the Company.

     SECTION 7.03: REGISTRATION PROCEDURES. If and whenever the Company is
required pursuant to this Article VII to use its best efforts to effect the
registration of the Registrable Securities under the Securities Act, the Company
will, as expeditiously as possible:

          (a) prepare and file with the SEC a Registration Statement which
includes the Registrable Securities and use its best efforts to cause such
Registration Statement to become and remain effective until the distribution
described in the registration statement has been completed or until the
participating Holders can sell all such Registrable Securities pursuant to Rule
144;

          (b) prepare and file with the SEC such amendments and supplements to
such Registration Statement and the Prospectus used in connection therewith as
may be necessary to keep such Registration Statement effective and to comply
with the provisions of the Securities Act with respect to the sale or other
disposition of Registrable Securities covered by such Registration Statement
whenever a Holder shall desire to sell or otherwise dispose of the same, but
only to the extent provided in this Article VII;

          (c) furnish to each participating Holder (and to each underwriter, if
any, of Registrable Securities) such number of copies of a Prospectus, including
a preliminary Prospectus, in conformity with the requirements of the Securities
Act, and such other documents, as such Holder may reasonably request in order to
facilitate the public sale or other disposition of the Registrable Securities;

          (d) use its best efforts to register or qualify the Registrable
Securities covered by such registration statement under such state securities or
blue sky laws of such jurisdiction as each participating Holder shall reasonably
request and do any and all other acts and things which may be necessary under
such securities or blue sky laws to enable such Holder to consummate the public
sale or other disposition in such jurisdictions of the Registrable Securities,
except that the Company shall not for any purpose be required to consent
generally to service of process or qualify to do business as a foreign
corporation in any jurisdiction wherein it is not so qualified;

          (e) before filing the Registration Statement or Prospectus or
amendments or supplements thereto, furnish to counsel selected by the
participating Holders copies of such documents proposed to be filed which shall
be subject to the reasonable approval of such counsel;

          (f) enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing underwriter of such
offer;

          (g) notify the participating Holders at any time when a Prospectus
relating to any Registrable Securities covered by such Registration Statement is
required to be delivered under the Securities Act, of the happening of any event
as a result of which the Prospectus included in such Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in light of the circumstances then existing
and promptly file such amendments and supplements as may be necessary so that,
as thereafter delivered to such Holders, such Prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing and use its best efforts to cause each
such amendment and supplement to become effective;

          (h) furnish at the request of the participating Holders on the date
that such Registrable Securities are delivered to the underwriters for sale in
connection with a registration pursuant to this Article VII an opinion, dated
such date, of the counsel representing the Company, for purposes of such
registration, in form and substance as is customarily given by company counsel
to the underwriters in an underwritten public offer addressed to the
underwriters, if any, and to such Holders, and (ii) a letter dated such date,
from the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offer, addressed to the underwriters and
to such Holders; and

          (i) use its best efforts to cause all such Registrable Securities to
be listed on the securities exchange or the Nasdaq National Market, if any, on
which the Company's Common Stock is then listed.

          The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish to the Company such
information regarding the distribution of such securities and such other
information as may otherwise be required to be included in such Registration
Statement, as the Company may from time to time reasonably request in writing.

          Each Holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon receipt of any notice from the Company of the
happening of any event of the kind described in paragraph (g) hereof, such
Holder will forthwith discontinue disposition of such Registrable Securities
covered by such Registration Statement or Prospectus until such Holder's receipt
of the copies of the supplemented or amended Prospectus, or until it is advised
in writing by the Company that the use of the applicable Prospectus may be
resumed, and has received copies of any additional or supplemental filings which
are incorporated by reference in such Prospectus, and, if so directed by the
Company, such Holder will deliver to the Company (at the Company's expense) all
copies, other than permanent file copies then in such Holder's possession, of
the Prospectus covering such Registrable Securities current at the time of
receipt of such notice.

     SECTION 7.04: INDEMNIFICATION. In the event Registrable Securities are
registered pursuant to this Article VII:

          (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder of Registrable Securities which are included in a
Registration Statement filed pursuant to the provisions of this Agreement and
any underwriter (within the meaning of the Securities Act) with respect to the
Registrable Securities, and each officer, director, employee and agent thereof
and each person, if any, who otherwise controls such Holder or underwriter
(within the meaning of the Securities Act), against any losses or claims,
damages, expenses or liabilities, joint or several, to which they may become
subject under the Securities Act, the Exchange Act or other federal or state
law, or otherwise, insofar as such losses, claims, damages, expenses or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue or allegedly untrue statement of any material fact contained in the
Registration Statement for the Registrable Securities, including any preliminary
Prospectus or final Prospectus contained therein or any amendments or
supplements thereto, or any document incident to the registration or
qualification of any Registrable Securities, 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 allegedly necessary to make the statements therein not
misleading or arise out of any violation or alleged violation by the Company of
the Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any state
securities law; and will reimburse such Holder, any underwriter, officer,
director, employee, agent or controlling person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 7.04(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, expense, liability or action
if such settlement is effected without the written consent of the Company, which
shall not be unreasonably withheld, nor shall the Company be liable under this
Section 7.04(a) to such Holder, such underwriter, officer, director, employee,
agent or controlling person for any such loss, claim, damage, expense, liability
or action to the extent that it arises out of, or is based upon, an untrue
statement or allegedly untrue statement or omission or alleged omission made in
connection with such Registration Statement, preliminary Prospectus, final
Prospectus, or amendments or supplements thereto, in reliance upon and in
conformity with information furnished in writing expressly for use in connection
with such registration by such Holder, such underwriter, officer, director,
employee, agent or such controlling person.

          (b) To the extent permitted by law, each Holder of Registrable
Securities which are included in a Registration Statement filed pursuant to the
provisions of this Agreement will indemnify and hold harmless the Company, each
of its employees, agents, directors and officers, each person, if any, who
controls the Company within the meaning of the Securities Act, and any
underwriter (within the meaning of the Securities Act) against any losses,
claims, damages, expenses or liabilities to which the Company or any such person
or underwriter may become subject, under the Securities Act, the Exchange Act or
other federal or state law or otherwise, insofar as such losses, claims,
damages, expenses or liabilities (or actions in respect thereof) arise out of,
or are based upon any untrue or allegedly untrue statement of any material fact
contained in a Registration Statement for the Registrable Securities, including
any preliminary Prospectus or final Prospectus contained therein or any
amendments or supplements thereto, or any document incident to the registration
or qualification of any Registrable Securities, 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 allegedly necessary to make the statements therein not
misleading; in each case to the extent that such untrue statement or allegedly
untrue statement or omission or alleged omission was made in such Registration
Statement, preliminary Prospectus, final Prospectus or amendments or supplements
thereto, in reliance upon and in conformity with information furnished in
writing by such Holder expressly for use in connection with such registration;
provided, however, that the indemnity agreement contained in this Section
7.04(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, expense, liability or action if such settlement is effected without the
written consent of such Holder, which shall not be unreasonably withheld; and
such Holder will reimburse the Company or any such person or underwriter for any
legal or other expenses reasonably incurred by the Company or any such person or
underwriter in connection with investigating or defending such loss, claim,
damage, liability, expense or action.

          (c) Promptly after receipt by an indemnified party under this Section
7.04 of notice of the commencement of any action, such indemnified party will,
if a claim in respect thereof is to be made against any indemnifying party under
this Section 7.04, notify the indemnifying party in writing of the commencement
thereof and generally summarize such action. The indemnifying party shall have
the right to participate in and to assume the defense thereof with counsel
mutually satisfactory to the parties. An indemnifying party shall not have the
right to direct the defense of such an action on behalf of an indemnified party
if such indemnified party has reasonably concluded that there may be defenses
available to it that are different from or additional to those available to the
indemnifying party; provided, however, that in such event, the indemnifying
party shall bear the fees and expenses of only one (1) separate counsel for all
indemnified parties, such separate counsel to be reasonably satisfactory to the
indemnifying party. The failure to notify an indemnifying party promptly of the
commencement of any such action if prejudicial to the ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 7.04, but the omission so to notify the
indemnifying party will not relieve such party of any liability that such party
may have to any indemnified party otherwise than under this Section.

          (d) To the extent permitted by law, the indemnification provided for
under this Section 7.05 will remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party or any officer,
director or controlling person (within the meaning of the Securities Act) of
such indemnified party and will survive the transfer of securities.

          (e) If for any reason the foregoing indemnity is unavailable to, or is
insufficient to hold harmless an indemnified party, then the indemnifying party
shall contribute to the amount paid or payable by the indemnified party as a
result of such losses, claims, damages, liabilities or expenses (i) in such
proportion as is appropriate to reflect the relative benefits received by the
indemnifying party on the one hand and the indemnified party on the other or
(ii) if the allocation provided by clause (i) above is not permitted by
applicable law, or provides a lesser sum to the indemnified party than the
amount hereinafter calculated, in such proportion as is appropriate to reflect
not only the relative benefits received by the indemnifying party on the one
hand and the indemnified party on the other but also the relative fault of the
indemnifying party and the indemnified party as well as any other relevant
equitable considerations. Notwithstanding the foregoing, no underwriter, if any,
shall be required to contribute any amount in excess of the amount by which the
total price at which the securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which
underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The obligation of any underwriters
to contribute pursuant to this Section 7.04(e) shall be several in proportion to
their respective underwriting commitments and not joint.

     SECTION 7.05: RESTRICTIONS ON PUBLIC SALE. Each holder of Registrable
Securities whose Registrable Securities are covered by a Registration Statement
filed pursuant to Article VII hereof agrees, if requested by the managing
underwriters in an underwritten offering, not to effect any public sale or
distribution of any securities of the Company of the same class as the
securities included in such Registration Statement, including a sale pursuant to
Rule 144 under the Securities Act (except as part of such underwritten
registration), during the 10-day period prior to, and during the 90-day period
beginning on, the closing date of the underwritten offering made pursuant to
such Registration Statement, to the extent timely notified in writing by the
managing underwriters.

          The foregoing provision shall not apply to any Holder if such Holder
is prevented by applicable statute or regulation from entering into any such
agreement. However, any such Holder shall undertake, in its request to
participate in any such underwritten offering, not to effect any public sale or
distribution of the applicable Registrable Securities commencing on the date of
sale of such applicable class of Registrable Securities unless it has provided
45 days' prior written notice of such sale or distribution to the underwriter or
underwriters.

     SECTION 7.06: REPORTS UNDER THE EXCHANGE ACT. With a view to making
available to the Holder the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder of Registrable Securities to sell such securities of the Company
to the public without registration, and with a view to making it possible for
any such holder to register the Registrable Securities pursuant to a
registration on Form S-3, the Company agrees, subject to this Article VII in the
case of Section 7.06(b), to:

          (a) make available adequate current public information as contemplated
by Rule 144 (c)(1) or (2);

          (b) take such action as is necessary to enable a Holder to utilize
Form S-3 for the sale of Registrable Securities;

          (c) file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

          (d) furnish to a Holder owning any Registrable Securities upon request
(i) a written statement by the Company that it has complied with the reporting
requirements of Rule 144, the Securities Act and the Exchange Act, or that it
qualifies as a registrant whose Registrable Securities may be resold pursuant to
Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent
annual or quarterly report of the Company and such other reports and documents
so filed by the Company, and (iii) such other information as may be reasonably
required in availing any Holder of Registrable Securities of any rule or
regulation of the SEC which permits the selling of any such Registrable
Securities without registration or pursuant to such form.

                                  ARTICLE VIII
                                  OTHER MATTERS

          1. DEFINED TERMS. For purposes of this Warrant:

          1.1 "Initial Public Offering" shall mean the first time after the date
of this Warrant at which an offering, whether primary or secondary, of shares of
Common Stock, options, warrants or securities convertible or exchangeable (with
or without payment of additional consideration) for shares of Common Stock or
rights to acquire shares of Common Stock is registered pursuant to an effective
registration statement filed by the Corporation under the Securities Act of
1933, as amended (the "Securities Act") (other than a registration statement
filed on Form S-4, or any successor form thereto, relating to a transaction
which, if consummated, would constitute a Surviving Combination.) An Initial
Public Offering will be deemed to be consummated (i) upon the first sale under
the related registration statement in the case of an underwritten offering and
(ii) when the related registration statement first becomes effective in the case
of an offering that is not underwritten.

          1.2 "Non-Surviving Combination" shall mean any merger, consolidation
or other business combination by the Corporation with one or more other Persons
in which any such other Person is the survivor, or a sale of all or
substantially all of the assets of the Corporation to one or more such other
Persons, and with respect to which cash and/or non-cash consideration is
distributed to holders of shares of Common Stock.

          1.3 "Person" shall mean individual, partnership, corporation, joint
venture, association, joint stock company, trust or unincorporated organization,
or a government or agency or political subdivision thereof.

          1.4 "Surviving Combination" shall mean any merger, consolidation or
other business combination by the Corporation with one or more other Persons in
which the Corporation is the survivor, or a purchase of assets by the
Corporation from one or more other Persons, if in either case the Corporation is
thereafter required to file reports with respect to its shares of Common Stock
with the Securities and Exchange Commission pursuant to Section 13 of the
Securities Exchange Act of 1934, as amended.

          1.5 "Triggering Event" shall mean any of the following events: (i) the
consummation of an Initial Public Offering by the Corporation; (ii) a
Non-Surviving Combination; or (iii) a Surviving Combination.

          2. DURATION AND EXERCISE OF WARRANT; EXERCISE PRICE; LIMITATION ON
EXERCISE; PAYMENT OF TAXES.

          2.1 EXERCISE PRICE. Subject to adjustment pursuant to section 6
hereof, the exercise price per Warrant Share to be purchased hereunder shall be
$6.78 (the "Exercise Price").

          2.2 PERIOD OF EXERCISE. This Warrant may be exercised, in whole, or
from time to time in part, only during the period from and after 9:00 A.M., Los
Angeles time, on the first day of July to and including 5:00 P.M., Los Angeles
time, on the 31st day of July in each of the years of 1991, 1992 and 1993 and at
any time from and after July 31, 1993; provided, however, that this Warrant may
also be exercised during the period from 9:00 A.M., New York City time; on the
day on which a Triggering Event first occurs, and to and including 5:00 P.M.,
Los Angeles time, on the earlier of (a) July 31, 1998 and (b) if the Triggering
Event is a sale of all or substantially all of the Corporation's assets, to be
followed by a liquidation of the Corporation, thirty (30) days following such
Triggering Event (the "Expiration Date"). The first day in July 1991, 1992 and
1993 and the day on which a Triggering Event first occurs is herein referred to
as an "Exercise Commencement Date."

          2.3 DURATION AND EXERCISE OF WARRANT.

               (a) The rights represented by this Warrant may be exercised by
the Warrantholder of record, in whole, or from time to time in part by the (a)
surrender of this Warrant, accompanied by the Exercise Form annexed hereto (the
"Exercise Form") duly executed by the Warrantholder of record and specifying the
number of Warrant Shares to be purchased, to the Corporation at the office of
the Corporation located at 3855 Avocado Boulevard, Suite 260, La Mesa,
California 92041 (or such other office or agency of the Corporation as it may
designate by notice to the Warrantholder at the address of such Warrantholder
appearing on the books of the Corporation) during normal business hours on any
day (a "Business Day") other than a Saturday, Sunday or a day on which national
banks are authorized to close in the City of Los Angeles, State of California or
on which the Corporation is otherwise closed for business (a "Nonbusiness Day")
on or after 9:00 A.M., Los Angeles time, on any Exercise Commencement Date but
not later than the close of business on the Expiration Date (or the close of
business on the next succeeding Business Day, if the Expiration Date is a
Nonbusiness Day), and (b) delivery of payment to the Corporation, for the
account of the Corporation, by cash, by certified or bank cashier's check or by
wire transfer, of the Exercise Price for the number of Warrant Shares specified
in the Exercise Form in lawful money of the United States of America. The
Corporation agrees that such Warrant Shares shall be deemed to be issued to the
Warrantholder as the record holder of such Warrant Shares as of the close of
business on the date on which this Warrant shall have been surrendered and
payment made for the Warrant Shares as aforesaid. Certificates for the Warrant
Shares specified in the Exercise Form shall be delivered to the Warrantholder as
promptly as practicable, and in any event within ten (10) Business Days,
thereafter. The certificate or certificates so delivered shall be issued in the
name of the Warrantholder or, if permitted by subsection 2.5 and in accordance
with the provisions thereof, such other name as shall be designated in the
Exercise Form, subject to subsection 2.4, and shall be subject to the
restrictions on transfer and bear the legend specified in subsection 2.5. If
this Warrant shall have been exercised only in part, the Corporation shall, at
the time of delivery of the certificate or certificates for the Warrant Shares,
deliver to the Warrantholder a new Warrant evidencing the rights to purchase the
remaining Warrant Shares, which new Warrant shall in all other respects be
identical with this Warrant. If this Warrant is not exercised prior to the close
of business on the Expiration Date (or the next succeeding Business Day, if the
Expiration Date is a Nonbusiness Day), this Warrant shall cease to be
exercisable and shall become void and all rights of the Warrantholder hereunder
shall cease. No adjustments or payments shall be made on or in respect of
Warrant Shares issuable on the exercise of this Warrant for any cash
distributions paid or payable to holders of record of shares of Common Stock
prior to the date as of which the Warrantholder shall be deemed to be the record
holder of such Warrant Shares.

               (b) No fractional shares of Common Stock shall be issued upon the
exercise of this Warrant. If more than one Warrant shall be exercised at one
time by the same holder, the number of Warrant Shares which shall be issuable
shall be computed on the basis of the aggregate principal amount of the Warrants
so exercised. With respect to any fraction of a share called for upon any
exercise hereof, the Corporation shall pay to the Warrantholder an amount in
cash equal to such fraction multiplied by, the difference between the "closing
price of the Corporation's Common Stock", determined as of the date of exercise
in accordance with subsection 7.5 hereof, and this Warrant's exercise price per
share of Common Stock as of the date of exercise.

          2.4 PAYMENT OF TAXES. The initial issuance of a certificate or
certificates, if any, for Warrant Shares upon the exercise of this Warrant shall
be made without charge to the Warrantholder for any securities transfer or other
issuance tax in respect thereto; PROVIDED, HOWEVER, that the Warrantholder shall
be required to pay any and all taxes which may be payable in respect to any
transfer involved in the issuance and delivery of any certificate or
certificates for Warrant Shares in a name other than that of the then
Warrantholder as reflected upon the books of the Corporation.

          2.5 TRANSFER RESTRICTIONS AND LEGEND.

               (a) This Warrant may not be sold, assigned, pledged,
hypothecated, encumbered, or in any manner transferred or disposed of, in whole
or in part, without the consent of the Corporation except by operation of law
or, in connection with a registration of Warrant Shares under the Securities
Act, to a member firm of the National Association of Securities Dealers, Inc.
Without limiting the generality of the foregoing, neither this Warrant nor any
of the Warrant Shares, nor any interest or participation in either, may be sold,
assigned, pledged, hypothecated, encumbered or in any other manner transferred
or disposed of, in whole or in part, except in compliance with applicable United
States federal and state securities laws and the terms and conditions hereof.

               (b) The Warrantholder agrees that prior to any transfer of this
Warrant or any transfer of the related Warrant Shares requiring the consent of
the Corporation under subsection 2.5(a) above, such Warrantholder will give
notice to the Corporation of its intention to effect such transfer (and, in the
case of a disposition, of the intended method of disposition), together with a
copy of the opinion of such Warrantholder's counsel, who shall be acceptable to
the Corporation, as to the necessity or non-necessity for registration under the
Act and applicable state securities laws in connection with such transfer. The
following provisions shall then apply:

                    (i) If in the opinion of the Warrantholder's counsel, the
proposed transfer of this Warrant or the proposed transfer of such Warrant
Shares may be effected without registration under the Act or applicable state
securities laws of this Warrant or such Warrant Shares, as the case may be, and
if the Corporation's counsel shall deliver an opinion to the Corporation to
substantially the same effect (for purposes of which it may rely on the opinion
of Warrantholder's counsel), then the Warrantholder shall be entitled to
transfer this Warrant or to transfer such Warrant Shares in accordance with the
intended method of disposition specified in the notice delivered by such holder
to the Corporation. The Corporation agrees to request said opinion of its
counsel promptly after receiving each such notice and opinion from the
Warrantholder and to deliver to said holder a copy of the opinion of the
Corporation's counsel promptly after it is received. The Warrantholder shall
cooperate fully, and provide the Corporation and its counsel with such
information and documents as either may reasonably request, to evaluate such
opinion. In the event that no such opinion of the Corporation's counsel (whether
such opinion shall concur with or dissent from said opinion of the
Warrantholder's counsel) shall be delivered to the Warrantholder within 30 days
after the date when the Warrantholder delivered said notice and opinion to the
Corporation, it shall not be necessary that any opinion of the Corporation's
counsel be delivered in order that any action be taken under this subsection,
and the Corporation shall thereafter be obligated in connection with said notice
and opinion of the Warrantholder's counsel to rely upon such Warrantholder's
counsel's opinion and effect such transfer.

                    (ii) If, in the opinion of either one or of both of said
counsel, either the proposed transfer of this Warrant or the proposed transfer
of such Warrant Shares may not be effected without registration under the
Securities Act or applicable state securities law of this Warrant or such
Warrant Shares, as the case may be, the Warrantholder shall not be entitled to
transfer this Warrant or to transfer such Warrant Shares, as the case may be.

               (c) Notwithstanding anything to the contrary contained in this
paragraph 2.5, this Warrant may be transferred in whole or from time to time in
part to any successor to the business of Oppenheimer or any affiliate, officer,
director, employee, parent, subsidiary or partner of Oppenheimer or by operation
of law in compliance with applicable United States federal and state securities
laws and such transfer shall not be subject to the provisions of subsection
2.5(b). Upon due presentation for registration of transfer of this Warrant
pursuant to this subsection 2.5(c), the Corporation shall execute and deliver in
the name of the transferee or transferees a new Warrant or Warrants in like
kind; provided, however, that such new Warrant or Warrants shall not contain the
provisions of this subsection 2.5(c).

               (d) In the case of Warrant Shares, each certificate therefor
shall bear a legend to the effect of the foregoing paragraph. Any Warrant issued
at any time in exchange or substitution for any Warrant bearing such a legend
shall also bear such legend unless, in the opinion of counsel for the
Corporation, the Warrant need no longer be subject to the restriction contained
herein. The provisions of this subsection 2.5 shall be binding upon all
subsequent holders of this Warrant, if any. Warrant Shares transferred to the
public as expressly permitted by, and in accordance with, the provisions of this
Warrant shall thereafter cease to be deemed to be "Warrant Shares" for purposes
hereof.

               (e) The Warrantholder represents that Warrantholder is acquiring
the Warrant (and, if exercised, the shares of Common Stock issuable upon such
exercise) for the Warrantholder's own account (or a trust account if
Warrantholder is a trustee) and not with a view to or for sale in connection
with any distribution of the securities.

          2.6 DIVISIBILITY OF WARRANT. Subject to securities law compliance,
this Warrant may be divided into warrants representing one Warrant Share or
multiples thereof, upon surrender at the principal office of the Corporation on
any Business Day, without charge to the Warrantholder. Upon any such division,
and, if permitted by subsection 2.5 and in accordance with the provisions
thereof, the Warrants may be transferred of record to a name other than that of
the Warrantholder of record; PROVIDED, HOWEVER, that the Warrantholder shall be
required to pay any and all transfer taxes with respect thereto.

         2.7 REGISTER. The Corporation shall maintain, at the principal office
of the Corporation (or such other office or agency of the Corporation in
_________________ as it may designate by notice to the holder hereof), a
register for the Warrants, in which the Corporation shall record the name and
address of the person in whose name a Warrant has been issued, as well as the
name and address of each transferee and each prior owner of such Warrant. Within
10 days after any holder of Warrants shall by notice request the same, the
Corporation will deliver to such holder a certificate, signed by a duly
authorized representative, listing the name and address of every other holder of
Warrants as such information appears in said register of the Corporation at the
close of business on the day before such certificate is signed.

          3. RESERVATION AND LISTING OF SHARES, ETC.

          The Corporation covenants and agrees that all Warrant Shares which are
issued upon the exercise of the rights represented by this Warrant will, upon
issuance, be validly issued, fully paid and non-assessable and free from all
taxes, liens, security interests, charges and other encumbrances with respect to
the issue thereof, other than taxes in respect of any transfer occurring
contemporaneously with such issue. The Corporation further covenants and agrees
that, during the period within which the rights represented by this Warrant may
be exercised, the Corporation will at all times have authorized and reserved,
and keep available free from preemptive rights, a sufficient number of shares of
Common Stock to provide for the exercise of the rights represented by this
Warrant, and will at its expense use its best efforts to procure such listing
thereof (subject to official notice of issuance) as then may be required on all
stock exchanges on which the Common Stock is listed.

          4. EXCHANGE, LOSS OR DESTRUCTION OF WARRANT.

          If permitted by subsection 2.5 and in accordance with the provisions
thereof, upon surrender of this Warrant to the Corporation with a duly executed
instrument of assignment and funds sufficient to pay any transfer tax, the
Corporation shall, without charge, execute and deliver a new Warrant of like
tenor in the name of the assignee named in such instrument of assignment and
this Warrant shall promptly be cancelled. Upon receipt by the Corporation of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and, in the case of loss, theft or destruction, of such bond or
indemnification as the Corporation may reasonably require, and, in the case of
such mutilation, upon surrender and cancellation of this Warrant, the
Corporation will execute and deliver a new Warrant of like tenor. The term
"Warrant" as used herein includes any Warrants issued in substitution or
exchange for this Warrant.

          5. OWNERSHIP OF WARRANT.

          The Corporation may deem and treat the person in whose name this
Warrant is registered as the Warrantholder and owner hereof (notwithstanding any
notations of ownership or writing hereon made by anyone other than the
Corporation) for all purposes and shall not be affected by any notice to the
contrary, until presentation of this Warrant for registration of transfer as
provided in subsections 2.3 and 2.5 or in section 4.

          6. CERTAIN ADJUSTMENTS.

          6.1 ADJUSTMENT OF WARRANT SHARES. The number of Warrant Shares
purchasable upon the exercise of this Warrant and the Exercise Price shall be
subject to adjustment as follows:

               (a) In case the Corporation shall (i) pay a dividend in shares of
Common Stock or make a distribution in shares of Common Stock, (ii) subdivide
its outstanding Shares, (iii) combine its outstanding shares of Common Stock
into a smaller number of shares of Common Stock or (iv) issue by
reclassification of its Shares of Common Stock other securities of the
Corporation (including any such reclassification in connection with a
consolidation or merger in which the Corporation is the surviving entity), the
number of Warrant Shares purchasable upon exercise of this Warrant shall be
adjusted so that the Warrantholder shall be entitled to receive the kind and
number of Warrant Shares or other securities of the Corporation which it would
have owned or have been entitled to receive after the happening of any of the
events described above, had this Warrant been exercised immediately prior to the
happening of such event or any record date with respect thereto. Any adjustment
made pursuant to this subsection (a) shall become effective immediately after
the effective date of such event retroactive to the record date, if any, for
such event.

               (b) Whenever the number of Warrant Shares purchasable upon the
exercise of the Warrant is adjusted, as herein provided, the Exercise Price
payable upon the exercise of this Warrant shall be adjusted by multiplying such
Exercise Price immediately prior to such adjustment by a fraction, the numerator
of which shall be the number of Warrant Shares purchasable upon the exercise of
the Warrant immediately prior to such adjustment, and the denominator of which
shall be the number of Warrant Shares purchasable immediately thereafter.

               (c) Irrespective of any adjustments of the number or kind of
securities issuable upon exercise of Warrants or the Exercise Price, Warrants
theretofore issued may continue to express the same number of Shares and
Exercise Price as are stated in similar Warrants previously issued.

          6.2 NOTICE OF ADJUSTMENT. Whenever the number of Warrant Shares or the
Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Corporation shall promptly mail by first class, postage prepaid, to all
Warrantholders, notice of such adjustment or adjustments and a certificate of a
firm of independent public accounts selected by the Board of Directors of the
Corporation (which may be the regular accountants employed by the Corporation)
setting forth the number of Warrant Shares and the Exercise Price of such
Warrant Shares after such adjustment, a brief statement of the facts requiring
such adjustment and the computation by which such adjustment was made. Such
certificate shall be conclusive evidence of the correctness of such adjustment.
If a dispute shall at any time arise with respect to the failure of the
Corporation to make any adjustments of the Exercise Price or the number of
Warrant Shares issuable pursuant to this Warrant, such dispute shall be
conclusively determined by such accountants. Any such determinations shall be
binding upon the Corporation, all Warrantholders and holders of Warrant Shares
and all other security holders of the Corporation.

          6.3 RIGHTS OF WARRANTHOLDERS TO CERTAIN DISTRIBUTIONS. If the
Corporation at any time makes any spin-off, split-up, split-off or distribution
of assets upon or with respect to its shares of Common Stock, as a liquidating
or partial liquidating dividend, spin-off or by way of return of capital, or
other than as a dividend payable out of current earnings, each Warrantholder
shall upon the exercise of the Warrant receive, in addition to the Warrant
Shares then issuable on exercise of the Warrant, the amount of such assets (or
at the option of the Corporation, a sum equal to the value thereof at the time
of the distribution) which would have been payable to such holder had he
exercised the Warrant immediately prior to the record date for such
distribution.

          6.4 PRESERVATION OF PURCHASE RIGHTS UPON MERGER, CONSOLIDATION, ETC.

               (a) If any capital reorganization or reclassification of any
shares of Common Stock, or consolidation or merger of the Corporation with
another corporation, or the sale of all or substantially all of its assets to
another entity, shall be effected while any Warrants are outstanding in such a
way that holders of any class of Common Stock shall be entitled to receive
stock, partnership interests, securities or assets with respect to or in
exchange for any class of such Common Stock, then as a condition of such
registration, reclassification, consolidation, merger or sale, lawful and
adequate provision shall be made whereby each Warrantholder shall thereafter
have the right to receive upon the basis and upon the terms and conditions
specified herein and in lieu of the Warrant Shares immediately theretofore
receivable upon the exercise of such Warrants, such number of shares of stock,
partnership interests, securities or assets to which a holder of the number of
Warrant Shares issuable upon the exercise of such Warrants would have been
entitled upon such reorganization, reclassification, consolidation, merger or
sale, and in any such case appropriate provision shall be made with respect to
the rights and interests of each such Warrantholder to the end that the
provisions hereof shall thereafter be applicable, as nearly as may be, in
relation to any shares of stock, partnership interests, securities or assets
thereafter deliverable upon the exercise of such Warrants. The Corporation shall
not effect any such consolidation, merger or sale unless prior to or
simultaneously with the consummation thereof the survivor or successor limited
partnership or corporation (if other than the Corporation) resulting from such
consolidation or merger or the limited partnership or corporation purchasing
such assets shall assume by written instrument executed and mailed or delivered
to each registered Warrantholder, the obligation to deliver to such
Warrantholder such shares of stock, partnership interests, securities or assets
as, in accordance with the foregoing provisions, such Warrantholder may be
entitled to receive, and containing the express assumption by such successor
limited partnership or corporation of the due and punctual performance and
observance of every provision of this Warrant to be performed and observed by
the Corporation and of all liabilities and obligations of the Corporation
hereunder.

               (b) In the event of any change in the rights of the Warrantholder
by reason of other events herein set forth, then and in each such case, the
Corporation will promptly obtain an opinion of Deloitte Haskins & Sells or of
another independent national firm of certified public accountants selected by
the Corporation, specifying the other shares of stock, partnership interests,
securities or assets and the amount thereof receivable as a result of such
change in rights, and setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based. The Corporation
will promptly mail a copy of such accountants' opinion to the registered
Warrantholder.

          7. REDEMPTION.

          7.1 In the event that the Warrantholder exercises his or its right to
include any Warrant Shares issuable, but not yet issued, on the exercise hereof
in a registration statement pursuant to section 8 hereof, then the Corporation
may compel the holder of this Warrant to sell [all or portion] of this Warrant
to the Corporation at a price equal to 95% of the difference between "the
closing price of the Corporation's Common Stock" on the date of Redemption
Notice (as hereinafter defined) and the Exercise Price then in effect.

          7.2 The Corporation shall give at least 10 days prior written notice
of any requested redemption ("Redemption Notice"), by mail, postage prepaid, to
each Warrantholder of record, Redemption Notice to be addressed to the holder at
the address as it appears on the stock transfer books of the Corporation and to
specify the date of redemption and amount of this Warrant to be redeemed. The
amount of this Warrant specified in such Redemption Notice shall be redeemed
automatically as of the date of redemption without any further action by the
Corporation or such holder and regardless of whether this Warrant is surrendered
to the Corporation or its transfer agent. On or after the date of redemption as
specified in such Redemption Notice, the holder shall surrender this Warrant.
Upon such surrender, the Corporation shall pay to such holder in cash or by
check the price for the [amount of this Warrant so redeemed.] [If less than all
of this Warrant is to be redeemed, the Corporation shall forthwith issue a new
Warrant, of like tenor, for the unredeemed portion of this Warrant.]

          7.3 If less than all of the series of Warrants, all of which this
Warrant is one, are to be redeemed, the Warrantholder acknowledges that the
particular Warrants in the series to be redeemed shall be selected by the
Corporation by such method as it shall deem fair and appropriate in its sole and
absolute discretion.

          7.4 Notwithstanding that this Warrant has been called for redemption,
this Warrant may be exercised in whole or in part during the periods specified
in subsection 2.2 hereof at any time before the date of redemption specified in
the Redemption Notice.

          7.5 For the purpose hereof, the "closing price of the Corporation's
Common Stock" on any Redemption Date 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 on the principal national
securities exchange on the Corporation's Common Stock is listed or admitted to
trading, or if it is not listed or admitted to trading on any national
securities exchange, on the National Market System, as reported by NASDAQ, or if
not admitted to trading on the National Market System, the average of the
closing bid and asked prices in the over-the-counter market as reported by
NASDAQ, or if not so available, the fair market price as determined by the
Corporation's Board of Directors (whose determination shall be conclusive) and
described in an officers' certificate signed by a responsible officer of the
Corporation. For purposes of this subsection the term "trading day" shall not
include any day on which securities are not traded on such exchange or in such
market.

          8. REGISTRATION OF THE WARRANTS AND/OR WARRANT SHARES.

          8.1 PIGGYBACK REGISTRATION.

          If at time after the date hereof, the Corporation proposes to file a
registration statement under the Securities Act with respect to a primary
offering by the Corporation for its own account (other than a "rights offering"
to shareholders of the Corporation) on a form suitable for a secondary offering
and/or a secondary offering on behalf of a shareholder of the Corporation, then
the Corporation will notify each Warrantholder (including for the purpose of
this section 8 any subsequent holder or holders of the Warrants and/or Warrant
Shares) at least thirty (30) days prior to the proposed filing of such
registration statement (the "Corporate Notice"), specifying in the Corporate
Notice the form of registration statement, the number of shares of Common Stock
or other securities which the Company proposes to register, the name of the
managing underwriter or underwriters (if any), (which may be Oppenheimer
pursuant to an existing agreement with the Corporation) and the general terms
and conditions of the proposed registration. Within fifteen (15) days of the
Corporate Notice, any Warrantholder may deliver a notice in writing to the
Corporation (the "Holder Notice") requesting that the Corporation include in
such registration statement some or all of the Warrant Shares. The Corporation
shall include the Warrant Shares in the registration statement, and, if any
proposed sale is to be underwritten, to see that the underwriters purchase such
Warrant Shares. In the event that any registration pursuant to this subsection
shall be, in whole or in part, an underwritten offering of securities of the
Corporation, any request by a Warrantholder pursuant to this subsection to
register the Warrant Shares must specify that such shares are to be included in
the underwriting on the same terms and conditions as the securities, if any,
otherwise being sold through underwriters under such registration; PROVIDED,
HOWEVER, that if the managing underwriter or underwriters of such offering
request in writing, at least fifteen (15) days prior to the date that the
registration statement becomes effective, that part or all of the Warrant Shares
be excluded from the registration statement on the ground that the inclusion of
such Warrant Shares with the securities which the other shareholders and the
Corporation propose to include in such offering will materially adversely affect
the success of the offering or offering price of the Common Stock being sold,
certain of the securities, including such Warrant Shares, will be excluded from
the registration statement as set forth below in this subsection. If the
underwriters agree to purchase any or all of the Warrant Shares, the
Warrantholders will enter into an underwriting agreement with the underwriters
and will sell such Warrant Shares to the underwriters unless and except to the
extent that, upon written notice to the Corporation and the managing underwriter
or underwriters at least two days prior to the effective date of the
registration statement, any such Warrantholder withdraws any portion of such
Warrant Shares. If the underwriters elect to reduce the amount of securities to
be offered and thereby purchase less than all of the Warrant Shares, such
reduction of Warrant Shares to be purchased by the underwriter shall be made pro
rata among the aggregate of Warrant Shares that were included in the timely
requests from Warrantholders under this subsection 8.1 and the shares of other
holders of the Corporation's securities with piggyback registration rights who
exercised their rights to participate in the subject registration statement. To
the extent Warrant Shares held by the Warrantholders are so reduced, such shares
will be excluded from the registration statement. Warrantholders shall have no
right to participate in the selection of the underwriters for the offering
pursuant to this subsection. The rights granted in this subsection 8.1 shall
expire five (5) years after the date hereof.

          8.2 DEMAND REGISTRATION.

               (a) At any time after the first anniversary of the Corporation's
Initial Public Offering but prior to the fifth anniversary of the date hereof,
any Warrantholder may at any time make a written request ("Demand Registration
Notice") for registration under and in accordance with the Securities Act of all
or part of its Warrant Shares (the "Demand Registration") provided that the
number of Warrant Shares requested to be registered by such Warrantholder shall
equal more than fifty percent (50%) of the aggregate number of Warrant Shares
issued and issuable. In such event, the Corporation shall promptly notify in
writing all other Warrantholders that it has received a Demand Registration
Notice and will, subject to the limitations described herein, include in such
registration all Warrant Shares with respect to which the Corporation has
received written requests for inclusion therein within thirty (30) business days
after receipt by the applicable holder of the notice of the Corporation's
receipt of the Demand Registration Notice. The Warrantholders will be entitled
to one such Demand Registration of such Warrant Shares for which registration
has been properly requested pursuant to this subsection 8.2, except as set forth
below.

               The Corporation and all other holders of Common Stock issued and
outstanding or reserved for future issuance pursuant to options, warrants and
conversion privileges as of the date of this Warrant, including, without
limitation, the holders of preferred stock ("Other Shareholders"), will be
permitted to participate in the registration statement filed pursuant to the
Demand Registration. If the Warrantholder or Warrantholders making the Demand
Registration so elect, the offering of Warrant Shares pursuant to such demand
registration will be in the form of an underwritten offering.

               In the event that the registration pursuant to this subsection
8.2 shall be in whole or in part an underwritten offering, if the managing
underwriter or underwriters of such offering advise the Corporation in writing
that in its or their opinion the amount of Warrant Shares proposed to be
included in such proposed offering is sufficiently large to materially adversely
affect the success of the offering or offering price of the Common Stock, the
Corporation will include in such registration only an amount of Warrant Shares
which in the opinion of such managing underwriter or underwriters can be sold
without such material adverse effect (the "Maximum Amount"). In such event, the
registration statement shall only include the number of Warrant Shares in the
Maximum Amount, and such amount shall be allocated in the following priority
order: (A) all Warrant Shares that Warrantholders exercising their rights
pursuant to the Demand Registration propose to sell up to the Maximum Amount;
and the balance of the Maximum Amount, if any, to (B) the Corporation and then
to (C) Other Shareholders. All allocations within categories (A), (B) and (C)
above will be made on a pro rata basis among the securities proposed to be
included in such registration by the respective shareholders.

               (b) Notwithstanding the foregoing, in the event that the Maximum
Amount represents less than fifty percent (50%) of the aggregate number of
Warrant Shares for which registration has been demanded under subsection 8.2(a),
then the Warrantholders shall be entitled to a second Demand Registration under
the terms and conditions set forth in this subsection 8.2; provided, however,
that the number of shares of Warrant Shares to be registered pursuant to such
second Demand Registration shall be more than fifty percent (50%) of the
aggregate number of Warrant Shares issued and issuable not previously registered
under the Securities Act.

               (c) Notwithstanding the obligations set forth in subsections (a)
and (b) above:

                    (i) The Corporation shall not be required to file any
registration statement which would require the inclusion of audited financial
statements for a period other than the Corporation's fiscal year;

                    (ii) Should any Warrantholder, upon receiving a Holder
Notice pursuant to subsection 8.1, not exercise his rights to include all of his
Warrant Shares in the registration statement referred to in such Holder Notice,
then such Warrantholder may not submit a Demand Registration Notice pursuant to
this subsection 8.2 until one hundred eighty (180) days after the effective date
of such registration statement.

         8.3 MARKET STAND-OFF. Each Warrantholder agrees that if the managing
underwriter or underwriters of the offering contemplated by subsection 8.1 so
request, such Warrantholder shall not sell any Requested Shares (as hereinafter
defined) or other Warrant Shares held by him not included in the registration
statement for a period of sixty (60) days after the effective date of the
registration statement filed in connection with the public offering; PROVIDED,
HOWEVER, that no Warrantholder shall be bound by this subsection 8.3 if none of
such Warrantholder's Warrant Shares have been included in the registration
statement filed pursuant to subsection 8.1.

         8.4 OBLIGATIONS OF THE CORPORATION. When required under this section 8
to effect the registration of any of the Warrant Shares under subsections 8.1 or
8.2 hereof (in either such case, the "Requested Shares"), the Corporation shall,
as expeditiously as is reasonably possible:

               (a) Prepare and file with the Securities Exchange Commission (the
"SEC") a registration statement with respect to such Requested Shares and such
amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to cause such registration
statement to become effective at the earliest practicable date and to remain
effective for a period of ninety (90) days or until the Warrantholders and any
underwriter purchasing such Requested Shares have sold or otherwise disposed of
the Requested Shares registered in such registration statement, whichever is
earlier.

               (b) Furnish to each Warrantholder selling Requested Shares such
number of copies of such registration statement, each supplement and amendment
thereto, a prospectus, including a preliminary prospectus, in conformity with
the requirements of the Securities Act, and such other documents as such
Warrantholder may from time to time reasonably request in order to facilitate
the disposition of Requested Shares to be sold by such Warrantholder pursuant to
such registration statement.

               (c) Register and qualify the Requested Shares covered by such
registration statement under such securities laws or state securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the Requested Shares covered by the registration statement; PROVIDED, HOWEVER,
that the Corporation shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

               (d) Furnish, at the request of any Warrantholder or
Warrantholders requesting registration of Requested Shares pursuant to this
section 8 on the date that such Requested Shares are delivered to the
underwriters for the sale pursuant to such registration or, if such Requested
Shares are not being sold through underwriters, on the date the registration
statement with respect to such Requested Shares becomes effective: (1) an
opinion, dated such date, of the counsel representing the Corporation for the
purposes of such registration, addressed to the underwriters, if any, and to the
Warrantholder or Warrantholders making such request, stating that such
registration statement has become effective under the Securities Act and that
(a) to the best knowledge of such counsel, no stop order suspending the
effectiveness thereof as has been issued and no proceedings for that purpose
have been instituted or are pending or contemplated under the Securities Act;
(b) the registration statement, the related prospectus, and each amendment or
supplement thereto, comply as to form in all material respects with the
requirements of the Securities Act and the applicable rules and regulations of
the SEC thereunder (except that such counsel need express no opinion as to
financial statements contained therein); (c) such counsel has no reason to
believe that either the registration statement or the prospectus, or any
amendment or supplement thereto, contains any untrue statement of a material
fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading; (d) to the best
knowledge of such counsel, the descriptions in the registration statement and
the prospectus, and any amendment or supplement thereto, of legal and
governmental matters and all contracts and other legal documents or instruments
are accurate and fairly present the information required to be shown; and (e)
such counsel does not know of any legal or governmental proceedings, pending or
contemplated, required to be described in the registration statement or
prospectus, or any amendment or supplement thereto, that are not described as
required, nor of any contracts or documents or instruments of a character
required to be described in the registration statement or prospectus or any
amendment or supplement thereto or to be filed as exhibits to the registration
statement that are not described and filed as required; and (2) a letter, dated
such date, from the independent public accountants of the Corporation, addressed
to the underwriters, if any, and to the Warrantholder or Warrantholders making
such request, stating that they are independent public accountants within the
meaning of the Securities Act and that, in the opinion of such accountants, the
financial statements and other financial data of the Corporation included in the
registration statement and the prospectus, and any amendment or supplement
thereto, comply as to form in all material respects with the applicable
accounting requirements of the Securities Act. Such letter from the independent
certified public accountants shall additionally cover such other financial
matters (including information as to the period ending not more than five
business days prior to the date of such letter) with respect to the registration
in respect of which such letter is being given as the Warrantholder or
Warrantholders of Requested Shares requesting such letter may reasonably
request.

               (e) Effect any notification registration, qualification and
listing on a securities exchange which shall be reasonably necessary to permit
the sale of such Requested Shares, if the Common Stock is then being traded on
an exchange.

          8.5 EXERCISE OF WARRANT. Nothing herein shall require a Warrantholder
holding any Warrants to have exercised any of its Warrants prior to making a
request under subsections 8.1 or 8.2 hereof for registration of shares of Common
Stock issuable upon the exercise of such Warrants; provided, however, that such
Warrants must be exercised not later than the date of the effectiveness of the
registration statement covering the shares of Common Stock issuable upon
exercise thereof, or such earlier date as shall be reasonably required by the
managing underwriter(s) in an underwritten offering. Nothing herein shall
require the Corporation to register the Warrants under the Securities Act or any
state securities law. Upon the exercise of this Warrant, any and all
registration rights granted in this section 8 shall survive and the holder of
Warrant Shares acquired upon exercise hereof, shall be entitled to the rights
granted herein with respect to such Warrant Shares.

          8.6 FURNISH INFORMATION. It shall be a condition precedent to the
obligation of the Corporation to take any action pursuant to this section 8 that
the Warrantholders promptly furnish to the Corporation such information
regarding them, the securities of the Corporation held by them and the intended
method of disposition of such securities as the Corporation shall reasonably
request and as shall be required in connection with the Corporation's
obligations under this section.

          8.7 REGISTRATION EXPENSES. All expenses incurred by the Corporation in
complying with this section 8, including without limitation, all registration
and filing fees, printing expenses, travel expenses, fees and disbursements of
counsel for the Corporation and the expense of any special audits incident to or
required by any such registration, shall be paid by the Corporation. The
Corporation shall not be responsible for any underwriters' fees, brokerage fees,
underwriting discounts and commissions with respect to such registration of the
Requested Shares, or the counsel fees incurred by Warrantholders.

          8.8 EXPANDED RIGHTS. From and after the fifth anniversary of this
Warrant, section 8 shall be extended through July 31, 1998 with the following
modifications:

               (a) The last sentence of subsection 8.1 shall be deleted.

               (b) The Warrantholders shall have the right to make two demands
for registration of the Warrant Shares, after the fifth anniversary of this
Warrant, under subsection 8.2(a). Subsection 8.2(b) shall be deleted. Upon
demand for registration of the Warrant Shares pursuant to subsection 8.2(a),
subsection 8.7 shall be amended to include the following:

                    (i) The expenses of registering the Warrant Shares upon the
first Demand Registration shall be borne by the Corporation.

                    (ii) HOWEVER, the expenses of registering the Warrant Shares
upon the second Demand Registration shall be borne by the Warrantholders.

          8.9 INDEMNIFICATION. In the event any of the Warrant Shares of a
Warrantholder is included in a registration statement pursuant to this section
8:

               (a) To the extent permitted by law, the Corporation will
indemnify and hold harmless each Warrantholder selling Requested Shares, any
underwriter (within the meaning of the Securities Act) with respect to the
Requested Shares, and each officer and director of and each person, if any, who
otherwise controls such Warrantholder or underwriter within the meaning of the
Securities Act, against any losses, claims, damages, expenses, or liabilities,
joint or several, to which they may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages, expenses or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue or
allegedly untrue statement of any material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements 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 allegedly necessary to make the statements therein not
misleading; and will reimburse each such Warrantholder, underwriter or
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this section 8 shall not apply to amounts paid in settlement of any such
loss, claim, damage, expense, liability or action if such settlement is effected
without the written consent of the Corporation which shall not be unreasonably
withheld, nor shall the Corporation be liable under this section 8 to such a
Warrantholder, underwriter or controlling person for any such loss, claim,
damage, expense, liability or action to the extent that it arises out of, or is
based upon, an untrue statement or allegedly untrue statement or omission or
alleged omission made in connection with such registration statement,
preliminary prospectus, final prospectus, or amendments or supplements thereto,
in reliance upon and in conformity with information furnished in writing
expressly for use in connection with such registration by such Warrantholder,
such underwriter or such controlling person.

               (b) To the extent permitted by law, each Warrantholder selling
Requested Shares pursuant to this section 8 will indemnify and hold harmless the
Corporation, each of its directors and officers, each person, if any, who
controls the Corporation within the meaning of the Securities Act, and any
underwriter for the Corporation (within the meaning of the Securities Act)
against any losses, claims, damages or liabilities to which the Corporation or
any such person or underwriter may become subject, under the Securities Act or
otherwise, insofar as such losses, claims, damages, expenses or liabilities (or
actions in respect thereto) arise out of, or are based upon, any untrue or
allegedly untrue statement of any material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements 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 allegedly necessary to make the statements therein not
misleading, in each case to the extent that such untrue statement or allegedly
untrue statement or omission or alleged omission was made in such registration
statement, preliminary prospectus, or amendments or supplements thereto, in
reliance upon and in conformity with information furnished in writing by such
Warrantholder expressly for use in connection with such registration; PROVIDED,
HOWEVER, that the indemnity agreement contained in this section 8 shall not
apply to amounts paid in settlement of any such loss, claim, damage, expense,
liability or action if such settlement is effected without the written consent
of such Warrantholder which shall not be unreasonably withheld; and each such
Warrantholder will reimburse the Corporation or any such person or underwriter
for any legal or other expenses reasonably incurred by the Corporation or any
such person or underwriter in connection with investigating or defending any
such loss, claim, damage, liability, expense or action.

               (c) Promptly after receipt by an indemnified party under this
section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any indemnifying party
under this section 8 notify the indemnifying party in writing of the
commencement thereof and generally summarize such action. The indemnifying party
shall have the right to participate in and to assume the defense thereof with
counsel mutually satisfactory to the parties; PROVIDED that each indemnified
party shall have the right to employ its own counsel in any such cash, but the
fees and expense of such counsel shall be at the expense of such indemnified
party unless the employment of such counsel shall have been authorized in
writing by the indemnifying party in connection with the defense of such action
or the indemnifying party shall not have employed counsel to have charge of the
defense of such action or such indemnified party or parties shall have
reasonably concluded that there may be defenses available to it or them that are
different from or additional to those available to the indemnifying party (in
which case the indemnifying party shall not have the right to direct the defense
of such action on behalf of the indemnified party or parties) in any of which
events the fees and expenses of such counsel shall be borne by the indemnifying
parties. The failure to notify an indemnifying party promptly of the
commencement of any such action if prejudicial to the ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this subsection (g), but the omission so to notify the
indemnifying party will not relieve such party of any liability that such party
may have to any indemnified party otherwise than under this section.

               (d) To the extent permitted by law, the indemnification provided
for under this Warrant will remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party or any officer,
director or controlling person (within the meaning of the Securities Act) of
such indemnified party and will survive the transfer of securities.

               (e) If for any reason the foregoing indemnity is unavailable to,
or is insufficient to hold harmless, an indemnified party, then the indemnifying
party shall contribute to the amount paid or payable by the indemnified party as
a result of such losses, claims, damages, liabilities or expenses (i) in such
proportion as is appropriate to reflect the relative benefits received by the
indemnifying party on the one hand and the indemnified party on the other or
(ii) if the allocation provided by clause (i) above is not permitted by
applicable law, or provides a lesser sum to the indemnified party then the
amount hereinafter calculated, in such proportion as is appropriate to reflect
not only the relative benefits received by the indemnifying party on the one
hand and the indemnified party on the other but also the relative fault of the
indemnifying party and the indemnified party as well as any other relevant
equitable considerations. Notwithstanding the foregoing, no underwriter, if any,
shall be required to contribute any amount in excess of the amount by which the
total price at which the securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which such
underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The obligation of any underwriters
to contribute pursuant to this subsection (e) shall be several in proportion to
their respective underwriting commitments and not joint.

               (f) As used in this section 8, the term "Person" shall mean an
individual, partnership, corporation, joint venture, association, stock company,
trust or unincorporated organization, or a government or agency or political
subdivision thereof.

          8.10 NO-ACTION LETTER OR OPINION OF COUNSEL IN LIEU OF REGISTRATION.
Notwithstanding anything else contained in this section 8, in the event that (i)
the Corporation shall have obtained from the SEC an "interpretative" or a
"no-action" letter in which the SEC has indicated that registration is not
required or that it will take no action if, without registration under the
Securities Act, any Warrantholder disposes of Requested Shares in the manner in
which such Warrantholder proposes to dispose of the Requested Shares, or (ii) in
the opinion of counsel for the Corporation, no registration under the Securities
Act is required in connection with such disposition, the Requested Shares shall
not be eligible for registration under this section, but if the Corporation
Holder receives a contrary opinion of its counsel, the Corporation will either
allow such shares to be registered pursuant to this Section 8 and reimburse the
Warrantholder for the reasonable costs of obtaining such opinion or obtain a
no-action letter from the SEC.

          8.11 PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Warrantholder may
participate in any underwritten registration hereunder unless such Warrantholder
(a) agrees to sell such Warrantholder's securities on the basis provided in any
underwriting arrangements approved by the Corporation and (b) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements.

          9. PRIOR NOTICE OF CERTAIN EVENTS. In case at any time:

               (a) the Corporation shall pay any dividends or make any
distribution to its holders of shares of Common Stock;

               (b) the Corporation proposes to make the Initial Public Offering;
or

               (c) there shall be any capital reorganization or reclassification
of the shares of Common Stock of the Corporation, including any subdivision,
split, combination or reverse split, or any consolidation or merger of the
Corporation with another corporation or a sale of all or substantially all of
its assets; or

               (d) there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Corporation; then, in any of said cases, the
Corporation shall give prior written notice, by first-class mail, postage
prepaid, addressed to the Warrantholder at the address of such Warrantholder as
shown on the registration books of the Corporation, of the date on which (i) the
books of the Corporation shall close or a record shall be taken for such
distribution or subscription rights, or (ii) such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up shall take place, as the case may be, or (iii) the registration
statement is expected to become effective. To the extent applicable, such notice
shall also specify the date as of which the Corporation's shareholders shall
participate in said distribution or subscription rights or shall be entitled to
exchange their shares of Common Stock for securities or other property
deliverable upon such reorganization, reclassification, consolidation, merger or
sale, dissolution, liquidation or winding-up, as the case may be. Such written
notice shall be given at least fifteen (15) days prior to (i) such applicable
event, (ii) the applicable record date or (iii) the date on which the
Corporation's transfer books are closed in respect thereto.

               In addition to the foregoing, the Corporation shall promptly
notify Warrantholders in writing, by first class mail, postage prepaid, of the

number of shares of Common Stock outstanding on such date, excluding any shares
of Common Stock which are issued in connection with such Triggering Event.
