THIS WARRANT AND THE SHARES OF COMMON STOCK PURCHASABLE HEREUNDER HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MUST BE HELD
INDEFINITELY UNLESS SUBSEQUENTLY REGISTERED UNDER SAID ACT OR AN EXEMPTION

OTHERWISE TRANSFERRED UNLESS SUCH SALE, PLEDGE, HYPOTHECATION OR OTHER
DISPOSITION SHALL HAVE BEEN REGISTERED UNDER SAID ACT OR AN EXEMPTION UNDER
SAID ACT IS AVAILABLE TO PERMIT SUCH WARRANT AND THE SHARES OF COMMON STOCK
PURCHASABLE HEREUNDER TO BE LEGALLY SOLD OR OTHERWISE TRANSFERRED WITHOUT SUCH
REGISTRATION. THIS WARRANT IS SUBJECT TO THE TERMS AND PROVISIONS SET FORTH
BELOW, INCLUDING OTHER RESTRICTIONS ON TRANSFERABILITY.


                                                     Dated:  April 25, 1996

                  Certain terms used in this Warrant are defined in Article
IV. This Warrant is one of three Warrants issued by the Company in connection
with the acquisition of Precision Aerotech, Inc. The Warrants are being issued
as of the date hereof to Banque Paribas, Paribas Principal, Inc. and to
Donaldson, Lufkin & Jenrette Securities Corporation. In the aggregate, as of
the date of issuance of such Warrants, the Warrants will be exercisable into
1,542,700 shares of Common Stock of the Company.


                                   ARTICLE I

                             EXERCISE OF WARRANTS

                  1.1 Method of Exercise. To exercise this Warrant in whole or
in part with respect to any Shares, the Holder shall deliver to the Company,
at the Warrant Agency, (a) this Warrant, (b) a written notice, in
substantially the form of the Subscription Notice attached hereto, of such
Holder's election to exercise this Warrant, which notice shall specify the
number of Shares of Common Stock to be purchased, the denominations of the
share certificate or certificates desired and the name or names in which such
certificates are to be registered and (c) payment of the Exercise Price with
respect to such Shares or cancellation of this Warrant with respect to a
number of Shares. If the Holder elects to pay the Exercise Price in money,
such payment may be made, at the election of the Holder, by cash, money order,
certified or bank cashier's check or wire transfer of immediately available
funds. If the Holder elects to pay the Exercise Price by cancelling this
Warrant with respect to Shares, the Exercise Price may be paid by cancelling
this Warrant with respect to that number of Shares whose aggregate Current
Market Price minus the aggregate Exercise Price is equal to the aggregate
Exercise Price with respect to the number of Shares to be received upon
exercise of this Warrant.

                  The Company shall, as promptly as practicable and in any
event within seven days thereafter, execute and deliver or cause to be
executed and delivered, in accordance with such notice, a certificate or
certificates, representing the aggregate number of Shares specified in said
notice. The share certificate or certificates so delivered shall be in such
denominations as may be specified in such notice or, if such notice shall not
specify denominations, in a denomination equal to the aggregate number of
Shares specified in said notice, and shall be issued in the name of

                                      2

<PAGE>



the Holder or such other name or names as shall be designated in such notice,
subject to any restrictions contained hereinbelow. Such certificate or
certificates shall be deemed to have been issued, and such Holder or, subject
to any restrictions contained hereinbelow, any other Person so designated to
be named therein shall be deemed for all purposes to have become a holder of
record of such shares, as of the date the aforementioned notice and the
Exercise Price is received by the Company. If this Warrant shall have been
exercised only in part, the Company shall, at the time of delivery of the
certificate or certificates, deliver to the Holder a new Warrant evidencing
the rights to purchase the remaining shares of Common Stock called for by this
Warrant, which new Warrant shall in all other respects be identical with this
Warrant, or, at the request of the Holder, appropriate notation may be made on
this Warrant which shall then be returned to the Holder. The Company shall pay
all expenses, taxes and other charges payable in connection with the
preparation, issuance and delivery of share certificates and new Warrants,
except that, if share certificates or Warrants shall be registered in a name
or names other than the name of the Holder, funds sufficient to pay all
transfer taxes payable as a result of such transfer shall be paid by the
Holder at the time of delivering the aforementioned notice of exercise or
promptly upon receipt of a written request of the Company for payment.

                  1.2 Shares To Be Fully Paid and Nonassessable. All shares of
Common Stock issued upon the exercise of this Warrant ("Warrant Common Stock")
shall be validly issued, fully paid and nonassessable, free of all liens,
taxes and other charges, and, if the Common Stock of any class is then listed
on any national securities exchange (as such term is used in the Exchange Act)
or quoted on NASDAQ, shall be duly listed or quoted thereon, as the case may
be.

                  1.3 No Fractional Shares To Be Issued. The Company shall not
be required to issue fractions of shares of Common Stock upon exercise of this
Warrant. If any fraction of a share would, but for this Section, be issuable
upon any exercise of this Warrant, in lieu of such fractional share the
Company shall pay to the Holder, in cash, an amount equal to the same fraction
of the Current Market Price per share of outstanding Common Stock on the
Business Day immediately prior to the date of such exercise.

                  1.4  Share Legend.  Each certificate for shares
of Common Stock issued upon exercise of this Warrant,


                                      3

<PAGE>



unless at the time of exercise such shares are registered under the Securities
Act, shall bear the following legend:

                  This security has not been registered under the Securities
         Act of 1933, as amended, and must be held indefinitely unless
         subsequently registered under said Act or an exemption from such
         registration is available. This security may not be sold, pledged,
         hypothecated or otherwise transferred unless such sale, pledge,
         hypothecation or other disposition shall have been registered under
         said act or such disposition is made in reliance upon an exemption
         from registration under said act.

                  Any certificate issued at any time in exchange or
substitution for any certificate bearing such legend (except a new certificate
issued upon completion of a public distribution pursuant to a registration
statement under the Securities Act covering such Shares) shall also bear such
legend unless, in the opinion of counsel selected by the holder of such
certificate and reasonably acceptable to the Company (who may be an employee
of such holder), the
securities represented thereby need no longer be subject to restrictions on
resale under the Securities Act.

                  1.5 Authorized Shares; Reservation of Shares for Issuance.
At all times while this Warrant is outstanding, the Company shall maintain its
corporate authority to issue, and shall reserve for issuance upon exercise of
this Warrant, such number of shares of Common Stock as shall be sufficient to
perform its obligations under this Warrant (after giving effect to any
adjustments to the number of Shares purchasable upon exercise of this Warrant
pursuant to Article III hereof).

                  1.6  Notification By The Company.  In case at any time:

             (i)  the Company shall declare any dividend or
         make any distribution upon its Common Stock; or

             (ii) the Company shall offer for sale, or shall otherwise issue
         (except upon exercise of the Existing Warrants), any additional
         shares of stock of any class or any other securities convertible into
         or exchangeable for shares of stock or any rights or options to 
         subscribe thereto; or

            (iii)  the Board of Directors of the Company shall
         authorize any capital reorganization, reclassification

                                      4


<PAGE>



         or similar transaction involving the capital stock of the Company, or
         a sale or conveyance of all or substantially all of the assets of the
         Company, or a consolidation, merger or business combination of the
         Company with another Person; or

             (iv)  actions or proceedings shall be authorized or
         commenced for a voluntary or involuntary dissolution,
         liquidation or winding-up of the Company;

then, in any one or more of such cases, the Company shall give written notice
to the Holder, at the earliest time legally practicable (and not less than 30
days before any record date or other date set for definitive action) of the
date on which (A) the books of the Company shall close or a record shall be
taken for such dividend, distribution or sale or other issuance or (B) such
reorganization, reclassification, sale, conveyance, consolidation, merger,
dissolution, liquidation or winding-up shall take place or be voted on by
stockholders of the Company, as the case may be. Such notice shall also
specify the date as of which the holders of the Common Stock of record shall
participate in said dividend, distribution, sale or other issuance or shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reorganization, reclassification, sale, conveyance,
consolidation, merger, dissolution, liquidation or winding-up, as the case may
be. If the action in question or the record date is subject to the
effectiveness of a registration statement under the Securities Act or to a
favorable vote of stockholders, the notice required by this Section 1.6 shall
so state.


                                  ARTICLE II

                    WARRANT AGENCY; TRANSFER, EXCHANGE AND
                            REPLACEMENT OF WARRANTS

                  2.1 Warrant Agency. The Company shall maintain, at its own
expense, an agency (the "Warrant Agency"), for certain purposes specified
herein and shall cause such Warrant Agency to remain open during normal
business hours on each Business Day in connection with the performance of its
obligations hereunder. The Company shall perform the obligations of the
Warrant Agency provided herein at its address at 645 Madison Avenue, New York,
New York 10022 or such other address as the Company shall specify by notice to
all Warrantholders.



                                      5

<PAGE>



                  2.2 Ownership of Warrant. The Company may deem and treat the
Person in whose name this Warrant is registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by any
Person other than the Company) 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 this Article II.

                  2.3 Transfer of Warrant. The Company agrees to maintain at
the Warrant Agency books for the registration of transfers of this Warrant and
all rights hereunder shall be registered, in whole or in part, on such books,
upon surrender of this Warrant at the Warrant Agency, together with a written
assignment of this Warrant duly executed by the Holder or its duly authorized
agent or attorney and funds sufficient to pay any transfer taxes payable upon
such transfer. Upon surrender the Company shall execute and deliver a new
Warrant or Warrants in the name of the assignee or assignees and in the
denominations specified in the instrument of assignment, and this Warrant
shall promptly be canceled. Notwithstanding the foregoing, a Warrant may be
exercised by a new holder without having a new Warrant issued.

                  2.4 Division or Combination of Warrants. Subject to
restrictions contained hereinbelow, this Warrant may be divided or combined
with other Warrants upon surrender hereof and of any Warrant or Warrants with
which this Warrant is to be combined at the Warrant Agency, together with a
written notice specifying the names and denominations in which the new Warrant
or Warrants are to be issued, signed by the holders hereof and thereof or
their respective duly authorized agents or attorneys. Subject to compliance
with Section 2.3 as to any permitted transfer which may be involved in the
division or combination, the Company shall execute and deliver a new Warrant
or Warrants in exchange for the Warrant or Warrants to be divided or combined
in accordance with such notice.

                  2.5 Loss, Theft, Destruction of Warrant Certificates. Upon
receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of any Warrant and, in the case of any such loss,
theft or destruction, upon receipt of indemnity or security reasonably
satisfactory to the Company (the Original Holder's or any institutional
Warrantholder's indemnity being satisfactory indemnity in the event of loss,
theft or destruction of any Warrant owned by such institutional holder), or,
in the case of any such


                                      6

<PAGE>



mutilation, upon surrender and cancellation of such Warrant, the Company will
make and deliver, in lieu of such lost, stolen, destroyed or mutilated
Warrant, a new Warrant of like tenor and representing the right to purchase
the same aggregate number of shares of Common Stock.

                  2.6 Expenses of Delivery of Warrants. The Company shall pay
all expenses, taxes (other than transfer taxes) and other charges payable in
connection with the preparation, issuance and delivery of Warrants and Common
Stock hereunder.

                  2.7 Restrictions on Transfer. (a) The Holder, by acceptance
hereof, represents and warrants that this Warrant, and upon exercise hereof
the holder of any Warrant Common Stock will represent and warrant, that any
shares of Warrant Common Stock are being acquired for its own account for
investment without any intent to make a public distribution thereof in
violation of the securities laws and that this Warrant and such Warrant Common
Stock may not be sold, encumbered or otherwise transferred except pursuant to
an effective Registration Statement under the Act or an exemption from such
registration requirement and, if an exemption shall be applicable, the Holder
or the holder of Warrant Common Stock shall have delivered an opinion of
counsel reasonably satisfactory to the Company that such registration is not
required under the Act.

                  (b) The Holder acknowledges that the Company may direct the
transfer agent for the Warrant and the Warrant Common Stock to note a stop
transfer order upon its records in respect of this Warrant and any
certificates evidencing shares of the Warrant Common Stock and that in the
event of any permitted sale, transfer or exchange of this Warrant, any Warrant
certificate issued by the Company shall bear the legend obtained on the front
part of this Warrant.

                  (c) As a condition to any sale, transfer or other
disposition of this Warrant, the transferee shall be required to make the
representations and warranties contained in Section 2.7(a) hereof and
acknowledge the stop transfer order and consent to the legend contained in
Section 2.7(b) hereof. The Warrant shall not be sold, pledged, transferred or
otherwise disposed of except in whole to an entity controlled by Donaldson,
Lufkin & Jenrette Securities Corporation.

                                  ARTICLE III

                            ANTIDILUTION PROVISIONS

                  3.1 Adjustment of Exercise Price and Number of Warrant
Shares. The number and kind of shares purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment and reset from
time to time upon the happening of certain events, as hereinafter described.

                  3.2  Mechanical Adjustments.  The number of
Shares and the Exercise Price shall be subject to
adjustment as follows:

                  (a) In case the Company shall at any time after the date of
         this Agreement (i) declare or pay a dividend in shares of Common
         Stock or make a distribution in shares of Common Stock to all holders
         of its Common Stock, (ii) subdivide its outstanding shares of Common
         Stock, (iii) combine its outstanding shares of Common Stock into a
         smaller number of shares of Common Stock or (iv) issue any shares of
         its capital stock in a reclassification or reorganization of the
         Common Stock (including any such reclassification in connection with
         a consolidation or merger in which the Company is the continuing
         entity), this Warrant shall be adjusted to the number of Shares and
         amount of any other securities, cash or other property of the Company
         which such Holder 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. An adjustment made
         pursuant to this paragraph (a) shall become effective immediately
         after the effective date of such event retroactive to the record
         date, if any, for such event. (b) Any Shares purchasable as a result
         of such adjustment shall not be issued prior to the effective date 
         of such event.

                  Other than if resulting in an adjustment pursuant to
         Section 3.2(a), in case the Company shall issue rights, options or
         warrants to subscribe for or purchase, or other securities
         exchangeable for or convertible into, shares of Common Stock (any
         such rights, options, warrants or other securities being herein
         called "Rights") to all holders of shares of its Common Stock whether
         or not such Rights are immediately exercisable or convertible, the
         Company shall issue

                                      8


<PAGE>



         such Rights to each Holder on the same basis as such Holder would
         have been entitled to receive such Rights if the Warrants had been
         exercised immediately prior to the happening of such event or the
         record date with respect thereto and no adjustment in the number and
         kind of Shares or Exercise Price shall be made under this Warrant in
         such circumstance.

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

                  (d) No adjustment in the number of Shares shall be required
         hereunder unless such adjustment would result in an increase or
         decrease of at least one percent (1%) of the Exercise Price;
         provided, however, that any adjustments which by reason of this
         paragraph (d) are not required to be made shall be carried forward
         and taken into account in any subsequent adjustment. All calculations
         shall be made to the nearest one-hundredth of a cent or to the
         nearest one-thousandth of a Share, as the case may be.

                  (e) No adjustment shall be made pursuant to this Article III
         in respect of the issuance of shares of Common Stock pursuant to the
         Existing Warrants. No adjustment need be made for a change in the par
         value of the Common Stock.

                  (f) For the purpose of this subsection 3.2, the term "shares
         of Common Stock" shall mean (i) the classes of stock designated as
         Common Stock at the date of this Agreement, (ii) any other class of
         stock resulting from successive changes or reclassifications of such
         shares consisting solely of changes in par value, or from par value
         to no par value, or from no par value to par value or (iii) any other
         capital stock of the Company which is not by its terms restricted in
         amount or timing to the entitlement to dividends. In the event that
         at any time, as a result of an adjustment made pursuant to this
         Section 3.2, the Holders shall become entitled to receive any
         securities of the Company other than shares of Common Stock,
         thereafter the number of such other securities so receivable upon
         exercise of this Warrant and the


                                      9

<PAGE>



         Exercise Price of such shares 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 Shares contained in
         this Article III.

                  3.3  Voluntary Adjustment by the Company.  The Company may 
         at its option, at any time during the term of this Warrant, reduce 
         the then current Exercise Price to any amount and for any period of 
         time deemed appropriate by the Board of Directors of the Company, 
         including such reductions in the Exercise Price as the Company 
         considers to be advisable in order that any event treated for Federal
         income tax purposes as a dividend of stock or stock rights shall not
         be taxable to the recipients; provided, however, that no such 
         adjustment in Exercise Price shall affect the number of Shares.

                  3.4 Notice of Adjustment. Whenever the number of Shares or
the Exercise Price is required to be adjusted, as herein provided, the Company
promptly shall mail by first class, postage prepaid, to each Holder, notice of
such adjustment or adjustments setting forth the number of Shares and the
Exercise Price after such adjustment, setting forth a brief statement of the
facts requiring such adjustment and setting forth the computation by which
such adjustment was made.

                  3.5 Dividends and Distributions. Other than if resulting in
an adjustment pursuant to Section 3.2(a) or issuance covered by 3.2(b), in
case the Company shall declare a dividend or make any other distribution upon
Common Stock (other than in shares of Common Stock), the Company shall hold
any property (including cash) paid in respect of such dividend or distribution
that the Holder would have received if the Holder had theretofore exercised
the Warrant for the benefit of the Holder and promptly pay same over to the
Holder.

                  3.6 Preservation of Purchase Rights upon Merger,
Consolidation, etc. In case of any consolidation of the Company with or merger
of the Company with or into another Person or in case of any sale, transfer or
lease to another Person of all or substantially all the assets of the Company,
the Company or such successor or purchasing Person, as the case may be, shall
agree (and such merger, consolidation or transfer of assets shall not be
consummated without such agreement) that each Holder thereafter shall have the
right only to receive, and such Warrant shall only represent the right to
receive, upon

                                      10


<PAGE>



payment of the Exercise Price in effect immediately prior to such action, the
kind and amount of shares and other securities, cash and other property which
he would have been entitled to receive after the happening of such con
solidation, merger, sale, transfer or lease had this Warrant been exercised
immediately prior to such action (provided that if the kind or amount of
securities, cash and other property receivable upon such consolidation,
merger, sale or transfer is not the same for each share of Common Stock of the
Company, then for the purpose of this Section the kind and amount of
securities, cash and other property receivable upon exercise of this Warrant
immediately after such consolidation, merger, sale or transfer shall be the
kind and amount so receivable per share by a majority of the holders of Common
Stock), and if the successor or purchasing Person is not a corporation, such
person shall provide appropriate tax indemnification with respect to such
shares and other securities and property so that upon exercise of the Warrant,
the Holder would have the same benefits it otherwise would have had if such
successor or purchasing Person were a corporation. 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 and that such
adjustments shall similarly apply to successive consolidations, mergers,
sales, transfers or leases.

                  3.7 Statement on Warrant Certificates. Irrespective of any
adjustments in the Exercise Price or the number or kind of Shares, this
Warrant may continue to express the same price and number and kind of shares
as are stated on the front page hereof.


                                  ARTICLE IV

                              REGISTRATION RIGHTS

                  4.1  Registration Rights.  If at any time or from
time to time:

                  (a) the Company shall determine to register any of its
securities (other than by means of a registration statement on a form (e.g.,
Form S-8 or Form S-4 or successor forms) which by its terms could not be used
for the sale and distribution of any Warrant Common Stock) the Company will:

                           (i) promptly (but not less than thirty (30)
days prior to the filing of any registration statement) give written notice
thereof (which shall include a list of the


                                      11

<PAGE>



jurisdictions, if any, in which the Company intends to register or qualify
such securities under the applicable blue sky or other state securities laws)
to each holder of Warrant Common Stock;

                           (ii) if so requested in writing by any holder
of Warrant Common Stock, use its best efforts to effect such registration and
any qualification any compliance relating thereto, including, without
limitation, the execution of an undertaking to file post-effective amendments,
appropriate qualification under applicable blue sky or other state securities
laws and appropriate compliance with the Securities Act and any other
governmental requirements or regulations as would permit or facilitate the
sale and distribution of all Warrant Common Stock, unless, in the opinion of
counsel to the Company reasonably acceptable to the holder of the Warrant
Common Stock who wishes to have them included in such registration statement,
registration under the Act is not required for the sale of such Warrant Common
Stock in the manner proposed by such holders. Notwithstanding the foregoing,
if any managing underwriter of the Company's offering shall advise the Company
in writing that, in its opinion, the distribution of all or a portion of the
Warrant Common Stock (the "Piggy-back Shares") requested to be included in the
registration statement currently with the securities being registered by the
Company would materially adversely affect the distribution of such securities
by the Company for its own account, then the holders of such Warrant Common
Stock shall delay their offering and sale of Warrant Common Stock (or the
portions thereof so designated by such managing underwriter) for such period,
not to exceed 180 days, as the managing underwriter shall request. In the
event of such delay, the Company shall file such supplements, post-effective
amendments or separate registration statement, and take any such other steps
as may be necessary to permit such holders to make their proposed offering and
sale for a period of 90 days immediately following the end of such period of
delay ("Piggy-back Termination Date"); provided, however, that if at the
Piggyback Termination Date the Piggy-back Shares are covered by a registration
statement which is, or is required to remain, in effect beyond the Piggy-back
Termination Date, the Company shall maintain in effect the registration
statement as it relates to the Piggy-back Shares for so long as such
registration statement remains or is required to remain in effect for any
other such securities.

                           (iii) bear all expenses in connection with
such registration, qualification and compliance, including,
without limitation, all registration and filing fees,

printing expenses, fees and disbursements of the Company's counsel (but
exclusive of the fees and disbursements of legal counsel retained by holders
of Warrant Common Stock) and expenses of any audits incident to or required by
any such registration, qualification or compliance, provided, that the Company
shall not, in any event, be required to bear the cost of any commissions and
compensation paid, and concessions and discounts allowed to, underwriters,
dealers or others performing similar functions in connection with the sale and
distribution of the Warrant Common Stock sold by any holders thereof.

                  4.2 No Additional Liability. Notwithstanding anything to the
contrary contained in this Section IV or elsewhere herein, the Company will
not, in any event, be obligated to qualify any Warrant Common Stock covered by
a registration statement under any blue sky or other state securities law if
the Company would by reason thereof be required to qualify to do business in
any jurisdiction where it is not then so qualified.

                  4.3  Notification; Continuation of Effectiveness. In the 
case of each registration, qualification and compliance pursuant to this 
Section IV, the Company will keep the holder of Warrant Common Stock promptly
advised in writing as to the initiation of proceedings for such registration, 
qualification and compliance and as to the completion thereof, and will advise,
upon request, of the progress of such proceedings. The Company will, at its 
expense, keep such registration, qualification and compliance effective for 
a period of 90 days after the later of (x) the effective date of such 
registration statement or (y) the last day on which the holder of this
Warrant is restricted in selling Warrant Common Stock, as set forth in 
Section 4.1(a)(ii) hereof.

                  4.4 Information from Holders. The Company may require the
holder of Warrant Common Stock, as a condition to having the Warrant Common
Stock included among the securities as to which any registration,
qualification or compliance referred to in this Section IV is being effected,
to furnish to the Company such reasonable information regarding the proposed
distribution of the Warrant Common Stock as the Company may request in writing
and as shall be required in connection with such registration, qualification
or compliance.

                  4.5  Prospectuses, etc.  The Company will, at its expense,
furnish to each holder of Warrant Common Stock with respect to which 
registration has been effected, such number


                                      13

<PAGE>



of prospectuses, offering circulars and other documents incident to such
registration and related qualification or compliance as such holder from time
to time may reasonably request.

                  4.6 Indemnification. The Company will indemnify each holder
of Warrant Common Stock (and each person, if any, who or which controls such
holder) and each underwriter of the Warrant Common Stock held by or issuable
to such holder, against all claims, losses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement
(or alleged untrue statement) of a material fact contained in any prospectus,
offering circular or other document (including any related registration
statement, notification or the like) incident to any registration,
qualification or compliance referred to in this section IV, or arising out of
or based on any omission (or alleged omission) to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, or any violation by the Company of any rule or regulation
promulgated under the Securities Act applicable to the Company and relating to
action or inaction required of the Company in connection with any such
registration, qualification or compliance, and will reimburse each such holder
of Warrant Common Stock (and each person, if any, who or which controls such
holder of Warrant Common Stock) and each such underwriter for any legal or any
other expenses reasonably incurred in connection with investigating or
defending any such claim, loss, damage, liability or action, provided, that
the Company will not be liable in any such case to the extent that any such
claim, loss, damage or liability arises out of or is based on any untrue
statement or omission based upon written information furnished to the Company
by an instrument duly executed by such holder of Warrant Common Stock (and
each person, if any, who or which controls such holder of Warrant Common
Stock) or underwriter and stated specifically to be for use therein. The
Company may require of such holder of Warrant Common Stock, as a condition to
having such Warrant Common Stock held or issuable to holder of Warrant Common
included among the securities as to which such registration, qualification or
compliance is being effected, that each such holder of Warrant Common Stock
and underwriter will indemnify the Company, its directors, and its officers
who sign the registration statement in respect of such registration against
all claims, losses, damages and liabilities (or actions in respect thereof)
arising out of or based on any untrue statement (or alleged untrue statement)
of a material fact contained in any written information furnished by such
holder for inclusion in the registration statement by such

                                      14


<PAGE>



holder of Warrant Common Stock or underwriter, as the case may be, or an
omission (or alleged omission) to state in any such written information a
material fact required to be stated therein or necessary to make the statement
therein not misleading.

                  4.7 Notice of Claim, etc. Each party entitled to
indemnification hereunder (the "Indemnified Party") shall give notice to the
party required to provide indemnification (the "Indemnifying Party") promptly
after such Indemnified Party has actual knowledge of any claim as to which
indemnity may be sought, and shall permit the Indemnifying Party to assume the
defense of any such claim or any litigation resulting therefrom, provided that
counsel for the Indemnifying Party shall be acceptable to the Indemnified
Party (which acceptance shall not be unreasonably withheld), and provided
further, that the failure of any Indemnified Party to give notice as provided
in this Section 4.7 shall not relieve the Indemnifying Party of its obligation
under Section 4.6.

                  4.8 Listing on Securities Exchanges, etc. The Company will,
at its expense, promptly list on each national securities exchange or
quotation system on which Common Stock is a the time listed, upon official
notice of issuance upon the exercise of the Warrant, all Warrant Common Stock,
provided that the Warrant Common Stock is registered under the Securities Act
of 1933.

                  4.9 Right to Deliver Cash. Notwithstanding the provisions of
this Warrant, the Company shall have the right, in lieu of including the
shares of Warrant Stock in a registration statement pursuant to Section 4.1(a)
to elect to purchase the Warrant Common Stock to be included in such
registration statement by delivering to a holder of Warrant Common Stock cash
in the amount ("Repurchase Amount") equal to the number of shares of Warrant
Common Stock to be included in such registration statement multiplied by an
amount equal to the closing price (or, if applicable, the average of the
closing bid and asked prices) of the Company's Common Stock on the last
trading day immediately preceding the day of notice by the Company pursuant to
Section 4.1(a)(i). If the Company elects to exercise its rights hereunder, it
