               The unpaid principal amount of any of the above advances under
the Note Agreement were exchangeable on 30 days' notice, in whole or in part,
for an equal amount of convertible debentures of the Company having the same
economic terms and conditions as the Company's existing 10% convertible
debentures due March 1, 1999, which in turn would have been convertible into
Common Stock at the option of the holder at the lesser of $1.00 or 85% of the
average 5-day closing bid price of the Company's Common Stock prior to
conversion. However, pursuant to the Amendment Agreement dated December 23,
1997, which Amendment Agreement is attached hereto as Exhibit 21 and
incorporated herein by reference (the "Amendment Agreement") the notes with
respect to the above advances ceased to be convertible. Any of the above
warrants may be exercised at any time on or prior to August 6, 2000 at an
exercise price of $0.70 per share. Common Stock issued pursuant to the Note
Agreement is unregistered.

               As consideration for execution of a standstill agreement, dated
as of July 14, 1997 (the "Standstill Agreement"), Partners received warrants for
90,000 shares of Common Stock of the Company. The warrants may be exercised at
any time on or prior to July 14, 2002 at an exercise price of $1.00 per share.
The Standstill Agreement changed the terms of convertibility into Common Stock
of certain securities of the Company as set forth therein, and is attached
hereto as Exhibit 11 and incorporated herein by reference.

               On July 23, 1997, Partners acquired 48 shares of Series F
Convertible Preferred Stock of the Company ("Series F Preferred"). Each share of
Series F Preferred has a liquidation preference of $10,000 plus interest, as set
out in the Series F Preferred Stock Certificate of Designation which is attached
hereto as Exhibit 20 and incorporated herein by reference and is

convertible into Common Stock based on the formula set forth in the Series F
Preferred Stock Certificate of Designation.

               As of August 19, 1997, Associates transferred all of its assets
and liabilities to Associates II, in exchange for 100% of the limited
partnership interests of Associates II (which constituted 99.8% of the total
partnership interests of Associates II). Upon such transfer, Associates ceased
to be a beneficial owner of the Common Stock of the Company within the meaning
of the Securities and Exchange Act of 1934, as amended, because it ceased to
have voting power or investment power with respect to such Common Stock. The
general partner of Associates II is Partners II, which owns the remaining 0.2%
of the total partnership interests of Associates II. The assets of Associates so
transferred included the following equity securities of the Company:

               At the same time, Partners assigned the Note Agreement to
Associates II with respect to all future advances.

               Since August 19, 1997, pursuant to the Note Agreement and in
consideration of advances made by Associates II in the amounts and on the dates
indicated below, Associates II received Common Stock (a portion of which
constituted a fee for extending the advances indicated) and warrants convertible

convertible debentures due March 1, 1999, which in turn would have been
convertible into Common Stock at the option of the holder at the lesser of $1.00
or 85% of the average 5-day closing bid price of the Company's Common Stock

terms as the advances made pursuant to the Note Agreement.  The parties are 
negotiating but have not yet finalized a note agreement with respect to these

               With respect to each of the above loans, it is expected that the
corresponding note, which the Company is obligated to issue and deliver but
which has not yet been issued and delivered, will not provide for conversion and
will be on substantially the same terms as the notes delivered pursuant to the
Note Agreement. The warrants, which the Company is obligated to issue and
deliver to Associates but which have not been so issued and delivered, are
expected to have an exercise price of $0.70 per share and to be exercisable at
any time prior to the third anniversary of the date of issue. The Common Stock
issued during this period is unregistered.

               This statement is amended by Associates and Partners and filed by

               Associates and Associates II are Delaware limited partnerships
with their principal business and principal office at 590 Madison Avenue, 32nd

               On September 29, 1997, Partners converted from a Delaware limited
partnership to a Delaware limited liability company in accordance with Delaware
law, and changed its name from Wolfensohn Partners L.P. to Wolfensohn Partners

amended its certificate of formation to change its name to Antiope Partners

                      occurred on December 15, 1997 and that the shares of
                      Series F Preferred were held for 125 days prior to

                      on an actual conversion may vary depending on market price

               As of December 24, 1997, Partners owns 185,142 shares of Common
Stock, which Partners estimates is approximately 0.4% of the total outstanding
shares of the Common Stock of Company. If Partners were to exercise all of its
rights to convert the Series F Preferred and the warrants into Common Stock, and
the lower price was assumed in the spread noted above, then Partners would be
deemed the beneficial holder of 2,428,427 shares of Common Stock, which is
estimated by Partners would constitute approximately 3.8% of the issued and

exercised and all outstanding convertible securities had been converted into

Common Stock, which is estimated by Partners II to represent approximately 1.2%
of the issued and outstanding shares of the Common Stock of the Company. (In
addition, see the holdings of Associates II, above in which Partners II is a
general partner and holds 0.2% of the total partnership interests).

II and Chairman of the Board and Chief Executive Officer of the Company, owns
327,266 shares of Common Stock and options to purchase 50,000 additional shares.
The 327,266 shares of Common Stock owned by Mr. Morgan is estimated to represent
0.7% of the total outstanding shares of the Common Stock of the Company. If Mr.
Morgan were to exercise all his options, he would be deemed the beneficial owner
of 377,266 shares of Common Stock, which is estimated by Mr. Morgan would
constitute approximately 0.6% of the issued and outstanding shares of the
Company (assuming all outstanding warrants had been exercised and all
outstanding securities had been converted into Common Stock as of December 15,

following legend restricting transfer of the securities it represents:

                  "The securities represented by this certificate have not been

         sale in the absence of an effective registration statement under the
         applicable securities laws or an exemption from such registration under
         such laws."

         In the event of a stock split or reverse split, stock dividend,
subdivision or similar event with respect to the Company's common stock or in
the event of any reorganization or recapitalization affecting the Company's
common stock, the number of shares or price per share specified for your options
is subject to adjustment so as to treat you fairly and put your option rights in
the same economic position as they were prior to such event. If any questions
should arise between you and the Company as to the appropriate adjustment, it
shall be determined by the Company's independent public accountants.

         Subject to the foregoing, you may exercise the options in whole or in
part any time or times within the five year period by delivering to the Company
at its principal office a writing signed by you and notifying the Company of
your exercise, accompanied by a check in the full amount of the purchase price
for the shares being purchased pursuant to the exercise at that time.

         The granting of these options, their exercise and the sale of the
Company's common stock acquired pursuant thereto may result in significant
federal income tax consequences. You may want to consult tax counsel concerning
this option.

         If you have any questions concerning the foregoing, please do not
hesitate to contact me.

                                                     Sincerely yours,

SECURITIES LAWS. NEITHER THIS WARRANT NOR ANY SUCH SHARES MAY BE SOLD, OFFERED

Warrant No. 32                                 For the Purchase of 29,499 Shares


                               LASERTECHNICS, INC.

                          COMMON STOCK PURCHASE WARRANT


                  THIS CERTIFIES THAT, for value received, Wolfensohn Associates
L.P. ("Wolfensohn") or its successors in interest, assigns or transferees
(collectively, the "Warrant Holder"), is entitled to subscribe for and purchase
from Lasertechnics, Inc., a Delaware corporation (the "Company"), 29,499 shares
of the Company's Common Stock (as defined in paragraph 10 hereof) (the "Warrant
Shares") at the "Exercise Price" (as hereinafter defined) per share, as the
number of Warrant Shares and the Exercise Price shall be adjusted and readjusted
or changed from time to time in accordance with paragraph 4 hereof. The Exercise
Price shall be the lesser of (i) $ 3.39 or (ii) if the Company completes an
equity financing of Five Million Dollars ($5,000,000) or more, on or before
December 31, 1996, the price per share at which shares of Common Stock are
issued in such financing or if such financing involves convertible or
exchangeable securities, the price at which such securities may be converted
into or exchanged for Common Stock.

                  This Warrant may be exercised at any time and from time to
time on or prior to December 31, 2001.

         1.       Exercise of Warrant.

                  The rights represented by this Warrant may be exercised by the
Warrant Holder, in whole or in part, by (a) delivering to the Company a duly
executed notice of exercise in the form of Annex A hereto and (b) at the Warrant
Holder's option, either (i) delivering a check payable to (or wire transfer to
the account of) the Company in an amount equal to the product of
<PAGE>   2
(x) the Exercise Price times (y) the number of Warrant Shares as to which this
Warrant is being exercised (such product, the "Total Exercise Price") or (ii)
delivering to the Company a letter (the "Conversion Letter") requesting
conversion or exchange of a portion of any indebtedness owed by the Company to
the Warrant Holder in an amount equal to the Total Exercise Price or (iii)
surrendering to the Company a portion of this Warrant with a "Value" (as defined
below) equal to the Total Exercise Price. For the purpose of clause (b) (iii)
above, "Value" shall mean the product of (I) the amount by which the average of
the closing prices of the Company's Common Stock on the thirty trading days
preceding the date of exercise, as reported in The Wall Street Journal, exceeds
the Exercise Price and (II) the number of Warrant Shares as to which this
Warrant is surrendered for the purpose of effecting payment for Warrant Shares.
This Warrant shall be deemed to have been exercised immediately prior to the
close of business on the date of delivery of a duly executed notice of exercise,
together with the amount (in cash or by delivering the Conversion Letter or by
surrender of a portion of this Warrant) payable upon exercise of this Warrant
and, as of such moment, (i) the rights of the Warrant Holder, as such, with
respect to the number of Warrant Shares as to which this Warrant is being
exercised (and, if applicable, surrendered as payment of the Total Exercise
Price) shall cease, and (ii) such Warrant Holder shall be deemed to be the
record holder of the shares of Common Stock issuable upon such exercise. As soon
as practicable after the exercise, in whole or in part, of this Warrant, and in
any event within 5 business days thereafter, the Company at its expense
(including the payment by it of any applicable issuance or stamp taxes) will
cause to be issued in the name of and delivered to the Warrant Holder, or as the
Warrant Holder (upon payment by the Warrant Holder of any applicable transfer
taxes) may direct, a certificate of certificates for the number of fully paid
and nonassessable shares of Common Stock to which the Warrant Holder shall be
entitled upon such exercise. In the event of partial exercise of this Warrant
and, if applicable, partial surrender of this Warrant pursuant to clause (b)
(iii) of this paragraph, the Warrant need not be delivered to the Company
provided that the Warrant Holder agrees to make a notation of such partial
exercise and, if applicable, surrender on the Warrant. If this Warrant is
delivered to the Company, the Company shall issue and deliver to the Warrant
Holder a new Warrant evidencing the rights to purchase the remaining Warrant
Shares, which new Warrant shall in all other respects be identical to this
Warrant.

         2.       Investment Representation.

                  The Warrant Holder by accepting this Warrant represents that
the Warrant Holder is acquiring this Warrant for its own account or the account
of an affiliate for investment purposes and not with the view to any offering or
distribution and that the Warrant Holder will not sell or otherwise dispose of
this Warrant or the underlying Warrant Shares in violation of applicable
securities laws. The Warrant Holder acknowledges that the certificates
representing any Warrant Shares will bear a legend indicating that they have not
been registered under the Act, and may not be sold by the Warrant Holder except
pursuant to an effective registration or pursuant to an



                                       2
<PAGE>   3
exemption from registration. Wolfensohn shall be entitled to include the Warrant
Shares in any demand or piggyback registration to which Wolfensohn is entitled
in respect of Common Stock held by it.

         3.       Validity of Warrant and Issue of Shares.

                  The Company represents and warrants that this Warrant has been
duly authorized and validly issued and warrants and agrees that all shares of
Common Stock that may be issued upon the exercise of the rights represented by
this Warrant will, when issued upon such exercise, be duly authorized, validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issue thereof. The Company further warrants and agrees that
during the period within which the rights represented by this Warrant may be
exercised, the Company will at all times have authorized and reserved a
sufficient number of shares of Common Stock to provide for the exercise of the
rights represented by this Warrant.

         4.       Antidilution Provisions.

                  The terms of this Warrant shall be subject to adjustment as
         follows:

                  (a) In case the Company shall (i) pay a stock dividend or make
         a distribution to holders of Common Stock in shares 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, or (iv) issue by reclassification of its shares of Common Stock
         any shares of capital stock of the Company, (A) the Exercise Price
         shall be increased or decreased, as the case may be, to an amount which
         shall bear the same relation to the Exercise Price in effect
         immediately prior to such action as the total number of shares
         outstanding immediately prior to such action shall bear to the total
         number of shares outstanding immediately after such action and (B) this
         Warrant automatically shall be adjusted so that it shall thereafter
         evidence the right to purchase the kind and number of Warrant Shares or
         other securities which the Warrant Holder would have owned and would
         have been entitled to receive after such action if this Warrant had
         been exercised immediately prior to such action or any record date with
         respect thereto. An adjustment made pursuant to this subparagraph (a)
         shall become effective retroactively immediately after the record date
         in the case of a dividend or distribution of Common Stock and shall
         become effective immediately after the effective date in the case of a
         subdivision, combination or reclassification.

                  (b) In case the Company shall fix a record date for the making
         of a distribution to all holders of Common Stock (including any such
         distribution made in connection with a consolidation or merger in which
         the Company is the continuing corporation) of (i) assets


                                       3
<PAGE>   4
         (other than cash dividends or cash distributions payable out of
         consolidated net income or retained earnings or dividends payable in
         Common Stock), (ii) evidences of indebtedness or other debt or equity
         securities of the Company, or of any corporation other than the Company
         (except for the Common Stock of the Company) or (iii) subscription
         rights, options or warrants to purchase any of the foregoing assets or
         securities, whether or not such rights, options or warrants are
         immediately exercisable (hereinafter collectively called "Distributions
         on Common Stock"), the Company shall make provisions for the Warrant
         Holder to receive upon exercise of this Warrant, a proportional amount
         (depending upon the extent to which this Warrant is exercised) of such
         assets, evidences of indebtedness, securities or such other rights, as
         if such Warrant Holder had exercised this Warrant on or before such
         record date.

                  (c) In case of any consolidation or merger of the Company with
         or into another corporation or the sale of all or substantially all of
         the assets of the Company to another corporation, this Warrant
         thereafter shall be exercisable for the kind and amount of shares of
         stock or other securities or property to which a holder of the number
         of shares of Common Stock of the Company deliverable upon exercise of
         this Warrant would have been entitled upon such consolidation, merger
         or sale; and, in such case, appropriate adjustment shall be made in the
         application of the provisions in this paragraph 4, to the end that the
         provisions set forth in this paragraph 4 (including provisions with
         respect to changes in and adjustments of the exercise price) shall
         thereafter be applicable, as nearly as reasonably may be, in relation
         to any shares of stock or other securities or property thereafter
         deliverable upon the exercise of this Warrant.

                  (d) If any event shall occur as to which the provisions of
         this paragraph 4 shall not be strictly applicable, but with respect to
         which the failure to make any adjustment to the Exercise Price and the
         number of Warrant Shares issuable upon exercise of this Warrant would
         not fairly protect the purchase rights represented by this Warrant in
         accordance with the intent and principles of this paragraph 4, upon
         request of the Warrant Holder, the Company shall appoint a firm of
         independent public accountants reasonably acceptable to the Warrant
         Holder which shall give its opinion upon the adjustments, if any,
         consistent with the intent and principles established in this paragraph
         4 necessary to preserve without dilution the purchase rights
         represented by this Warrant. Upon receipt of such opinion, the Company
         will promptly mail a copy thereof to the Warrant Holder and shall make
         the adjustments described therein.

                  (e) Upon the occurrence of each adjustment or readjustment of
         the exercise price or any change in the number of Warrant Shares or in
         the shares of stock or other securities or property deliverable upon
         exercise of this Warrant pursuant to this paragraph 4, the Company at
         its expense shall promptly compute such adjustment or readjustment


                                       4
<PAGE>   5
         and change in accordance with the terms hereof and furnish to each
         holder hereof a certificate signed by the chief financial officer of
         the Company, setting forth such adjustment or readjustment and change
         and showing in detail the facts upon which such adjustment or
         readjustment and change is based. The Company shall, upon the written
         request at any time of the Warrant Holder, furnish or cause to be
         furnished to such Holder, a similar certificate setting forth (i) such
         adjustment or readjustment and change, (ii) the Exercise Price then in
         effect, and (iii) the number of Warrant Shares and the amount, if any,
         of other shares of stock and other securities and property which would
         be received upon the exercise of the Warrant.

                  (f) The Company shall not be required upon the exercise of
         this Warrant to issue any fraction of shares, but shall make any
         adjustment therefor by rounding the number of shares obtainable upon
         exercise to the next highest whole number of shares.

         5.       Notice to Warrant Holder.

                  If at any time,

                  (a) the Company shall take any action which would require an
         adjustment in the Exercise Price or in the number of Warrant Shares
         pursuant to paragraph 4; or

                  (b) the Company shall authorize the granting to the holders of
         its Common Stock of any Distributions on Common Stock as set forth in
         paragraph 4(b), and notice thereof shall be given to holders of Common
         Stock; or

                  (c) the Company shall issue any additional shares of Common
         Stock or declare any dividend (or any other distribution) on its Common
         Stock (other than its regular quarterly dividends); or

                  (d) there shall be any capital reorganization or
         reclassification of the Common Stock (other than a change in par value
         or from par value to no par value or from no par value to par value of
         the Common Stock), or any consolidation or merger to which the Company
         is a party, or any sale or transfer of all or substantially all of the
         assets of the Company; or

                  (e) there shall be a voluntary or involuntary dissolution,
         liquidation or winding-up of the Company;

then, in any one or more of said cases, the Company shall give written notice to
the Warrant Holder, not less than 20 days before any record date or other date
set for definitive action, or of


                                       5
<PAGE>   6
the date on which such reorganization, reclassification, sale, consolidation,
merger, dissolution, liquidation or winding-up shall take place, as the case may
be. Such notice shall also set forth such facts as shall indicate the effect of
such action (to the extent such effect may be known at the date of such notice)
on the current Exercise Price and the kind and amount of the Warrant Shares and
other securities and property deliverable upon exercise of this Warrant. Such
notice shall also specify the date as of which the holders of the Common Stock
of record shall be entitled to exchange their Common Stock for securities or
other property deliverable upon such reorganization, reclassification, sale,
consolidation, merger, dissolution, liquidation or winding-up, as the case may
be.

         6.       Transfer of Rights.

                  This Warrant is transferable in whole or in part, at the
option of the Warrant Holder upon delivery of the Warrant Assignment Form
annexed as Annex B hereto, duly executed. The Company shall execute and deliver
a new Warrant or Warrants in the form of this Warrant with appropriate changes
to reflect the issuance of subsequent Warrants, in the name of the assignee or
assignees named in such instrument of assignment and, if the Warrant Holder's
entire interest is not being transferred or assigned, in the name of the Warrant
Holder, and this Warrant shall promptly be cancelled. Any transfer or exchange
of this Warrant shall be without charge to the Warrant Holder and any new
Warrant or Warrants issued shall be dated the date hereof. The term "Warrant" as
used herein includes any Warrants into which this Warrant may be divided or for
which it may be exchanged.

         7.       Lost, Mutilated or Missing Warrant.

                  Upon receipt by the Company of evidence satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant, and upon surrender
and cancellation of this Warrant, if mutilated, the Company shall execute and
deliver a new Warrant of like tenor and date.

         8.       Rights of Warrant Holder.

                  The Warrant Holder shall not, by virtue hereof, be entitled to
any voting or other rights of a shareholder of the Company, either at law or
equity, and the rights of the Warrant Holder are limited to those expressed in
this Warrant.

         9.       Successors.

                  All the provisions of this Warrant by or for the benefit of
the Company or the Warrant Holder shall bind and inure to the benefit of their
respective successors and assigns.

         consideration into which such currently authorized Common Stock may
         hereafter have been changed.

Warrant No. 33                                 For the Purchase of 17,668 Shares


                               LASERTECHNICS, INC.

                          COMMON STOCK PURCHASE WARRANT

                  THIS CERTIFIES THAT, for value received, Wolfensohn Associates
L.P. ("Wolfensohn") or its successors in interest, assigns or transferees
(collectively, the "Warrant Holder"), is entitled to subscribe for and purchase
from Lasertechnics, Inc., a Delaware corporation (the "Company"), 17,668 shares
of the Company's Common Stock (as defined in paragraph 10 hereof) (the "Warrant
Shares") at the "Exercise Price" (as hereinafter defined) per share, as the
number of Warrant Shares and the Exercise Price shall be adjusted and readjusted
or changed from time to time in accordance with paragraph 4 hereof. The Exercise
Price shall be the lesser of (i) $2.83 or (ii) if the Company completes an
equity financing of Five Million Dollars ($5,000,000) or more, on or before
December 31, 1996, the price per share at which shares of Common Stock are
issued in such financing or if such financing involves convertible or
exchangeable securities, the price at which such securities may be converted
into or exchanged for Common Stock.

                  This Warrant may be exercised at any time and from time to
time on or prior to December 31, 2001.

         1.       Exercise of Warrant.

         The rights represented by this Warrant may be exercised by the Warrant
Holder, in whole or in part, by (a) delivering to the Company a duly executed
notice of exercise in the form of Annex A hereto and (b) at the Warrant Holder's
option, either (i) delivering a check payable to (or wire transfer to the
account of) the Company in an amount equal to the product of (x) the Exercise
Price times (y) the number of Warrant Shares as to which this Warrant is being
exercised (such product, the "Total Exercise Price") or (ii) delivering to the
Company a letter (the "Conversion Letter") requesting conversion or exchange of
a portion of any indebtedness owed by the Company to the Warrant Holder in an
amount equal to the Total Exercise Price or (iii) surrendering to the Company a
portion of this Warrant with a "Value" (as defined below) equal to the Total
Exercise Price. For the purpose of clause (b) (iii) above, "Value" shall mean
the





<PAGE>   2
product of (I) the amount by which the average of the closing prices of the
Company's Common Stock on the thirty trading days preceding the date of
exercise, as reported in The Wall Street Journal, exceeds the Exercise Price and
(II) the number of Warrant Shares as to which this Warrant is surrendered for
the purpose of effecting payment for Warrant Shares. This Warrant shall be
deemed to have been exercised immediately prior to the close of business on the
date of delivery of a duly executed notice of exercise, together with the amount
(in cash or by delivering the Conversion Letter or by surrender of a portion of
this Warrant) payable upon exercise of this Warrant and, as of such moment, (i)
the rights of the Warrant Holder, as such, with respect to the number of Warrant
Shares as to which this Warrant is being exercised (and, if applicable,
surrendered as payment of the Total Exercise Price) shall cease, and (ii) such
Warrant Holder shall be deemed to be the record holder of the shares of Common
Stock issuable upon such exercise. As soon as practicable after the exercise, in
whole or in part, of this Warrant, and in any event within 5 business days
thereafter, the Company at its expense (including the payment by it of any
applicable issuance or stamp taxes) will cause to be issued in the name of and
delivered to the Warrant Holder, or as the Warrant Holder (upon payment by the
Warrant Holder of any applicable transfer taxes) may direct, a certificate or
certificates for the number of fully paid and nonassessable shares of Common
Stock to which the Warrant Holder shall be entitled upon such exercise. In the
event of partial exercise of this Warrant and, if applicable, partial surrender
of this Warrant pursuant to clause (b) (iii) of this paragraph, the Warrant need
not be delivered to the Company provided that the Warrant Holder agrees to make
a notation of such partial exercise and, if applicable, surrender on the
Warrant. If this Warrant is delivered to the Company, the Company shall issue
and deliver to the Warrant Holder a new Warrant evidencing the rights to
purchase the remaining Warrant Shares, which new Warrant shall in all other
respects be identical to this Warrant.

         2.       Investment Representation.

         The Warrant Holder by accepting this Warrant represents that the
Warrant Holder is acquiring this Warrant for its own account or the account of
an affiliate for investment purposes and not with the view to any offering or
distribution and that the Warrant Holder will not sell or otherwise dispose of
this Warrant or the underlying Warrant Shares in violation of applicable
securities laws. The Warrant Holder acknowledges that the certificates
representing any Warrant Shares will bear a legend indicating that they have not
been registered under the Act, and may not be sold by the Warrant Holder except
pursuant to an effective registration or pursuant to an exemption from
registration. Wolfensohn shall be entitled to include the Warrant Shares in any
demand or piggyback registration to which Wolfensohn is entitled in respect of
Common Stock held by it.

         3.       Validity of Warrant and Issue of Shares.

         The Company represents and warrants that this Warrant has been duly
authorized and validly issued and warrants and agrees that all shares of Common
Stock that may be issued upon the exercise of the rights represented by this
Warrant will, when issued upon such exercise, be duly authorized, validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issue thereof. The Company further warrants and agrees that
during the period within which the rights represented by this Warrant may be
exercised, the Company will at all times have authorized and reserved a
sufficient number of shares of Common Stock to provide for the exercise of the
rights represented by this Warrant.

         4.       Antidilution Provisions.

                  The terms of this Warrant shall be subject to adjustment as
follows:

         (a) In case the Company shall (i) pay a stock dividend or make a
distribution to holders of Common Stock in shares 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, or (iv) issue by
reclassification of its shares of Common Stock any shares of capital stock of
the Company, (A) the Exercise Price shall be increased or decreased, as the case
may be, to an amount which shall bear the same relation to the Exercise Price in
effect immediately prior to such action as the total number of shares
outstanding immediately prior to such action shall bear to the total number of
shares outstanding immediately after such action and (B) this Warrant
automatically shall be adjusted so that it shall thereafter evidence the right
to purchase the kind and number of Warrant Shares or other securities which the
Warrant Holder would have owned and would have been entitled to receive after
such action if this Warrant had been exercised immediately prior to such action
or any record date with respect thereto. An adjustment made pursuant to this
subparagraph (a) shall become effective retroactively immediately after the
record date in the case of a dividend or distribution of Common Stock and shall
become effective immediately after the effective date in the case of a
subdivision, combination or reclassification.

         (b) In case the Company shall fix a record date for the making of a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of (i) assets (other than cash dividends or cash
distributions payable out of consolidated net income or retained earnings or
dividends payable in Common Stock), (ii) evidences of indebtedness or other debt
or equity securities of the Company, or of any corporation other than the
Company (except for the Common Stock of the Company) or (iii) subscription
rights, options or warrants to purchase any of the foregoing assets or
securities, whether or not such rights, options or warrants are immediately
exercisable (hereinafter collectively called "Distributions on Common Stock"),

Company shall make provisions for the Warrant Holder to receive upon exercise of
this Warrant, a proportional amount (depending upon the extent to which this
Warrant is exercised) of such assets, evidences of indebtedness, securities or
such other rights, as if such Warrant Holder had exercised this Warrant or on
before such record date.

         (c) In case of any consolidation or merger of the Company with or into
another corporation or the sale of all or substantially all of the assets of the
Company to another corporation, this Warrant thereafter shall be exercisable for
the kind and amount of shares of stock or other securities or property to which
a holder of the number of shares of Common Stock of the Company deliverable upon
exercise of this Warrant would have been entitled upon such consolidation,
merger, or sale; and, in such case, appropriate adjustment shall be made in the
application of the provisions in this paragraph 4, to the end that the
provisions set forth in this paragraph 4 (including provisions with respect to
changes in and adjustments of the exercise price) shall thereafter be
applicable, as nearly as reasonably may be, in relation to any shares of stock
or other securities or property thereafter deliverable upon the exercise of this
Warrant.

         (d) If any event shall occur as to which the provisions of this
paragraph 4 shall not be strictly applicable, but with respect to which the
failure to make any adjustment to the Exercise Price and the number of Warrant
Shares issuable upon exercise of this Warrant would not fairly protect the
purchase rights represented by this Warrant in accordance with the intent and
principles of this paragraph 4, upon request of the Warrant Holder, the Company
shall appoint a firm of independent public accountants reasonably acceptable to
the Warrant Holder which shall give its opinion upon the adjustments, if any,
consistent with the intent and principles established in this paragraph 4
necessary to preserve without dilution the purchase rights represented by this
Warrant. Upon receipt of such opinion, the Company will promptly mail a copy
thereof to the Warrant Holder and shall make the adjustments described therein.

         (e) Upon the occurrence of each adjustment or readjustment of the
exercise price or any change in the number of Warrant Shares or in the shares of
stock or other securities or property deliverable upon exercise of this Warrant
pursuant to this paragraph 4, the Company at its expense shall promptly compute
such adjustment or readjustment and change in accordance with the terms hereof
and furnish to each holder hereof a certificate signed by the chief financial
officer of the Company, setting forth such adjustment or readjustment and change
and showing in detail the facts upon which such adjustment or readjustment and
change is based. The Company shall, upon the written request at any time of the
Warrant Holder, furnish or cause to be furnished to such Holder, a similar
certificate setting forth (i) such adjustment or readjustment and change, (ii)
the Exercise Price then in effect, and (iii) the number of Warrant Shares and
the amount, if any, of other shares of stock and other securities and property
which would be received upon the exercise of the Warrant.

         (f) The Company shall not be required upon the exercise of this Warrant
to issue any fraction of shares, but shall make any adjustment therefor by
rounding the number of shares obtainable upon exercise to the next highest whole
number of shares.

5.       Notice to Warrant Holder.  If at any time,

                  (a) the Company shall take any action which would require an
         adjustment in the Exercise Price or in the number of Warrant Shares
         pursuant to paragraph 4; or

                  (b) the Company shall authorize the granting to the holders of
         its Common Stock of any Distributions on Common Stock as set forth in
         paragraph 4(b), and notice thereof shall be given to holders of Common
         Stock; or

                  (c) the Company shall issue any additional shares of Common
         Stock or declare any dividend (or any other distribution) on its Common
         Stock (other than its regular quarterly dividends); or

                  (d) there shall be any capital reorganization or
         reclassification of the Common Stock (other than a change in par value
         or from par value to no par value or from no par value to par value of
         the Common Stock), or any consolidation or merger to which the Company
         is a party, or any sale or transfer of all or substantially all of the
         assets of the Company; or

                  (e) there shall be a voluntary or involuntary dissolution,
         liquidation or winding-up of the Company;

then, in any one or more of said cases, the Company shall give written notice to
the Warrant Holder, not less than 20 days before any record date or other date
set for definitive action, or of the date on which such reorganization,
reclassification, sale, consolidation, merger, dissolution, liquidation or
winding up shall take place, as the case may be. Such notice shall also set
forth such facts as shall indicate the effect of such action (to the extent such
effect may be known at the date of such notice) on the current Exercise Price
and the kind and amount of the Warrant Shares and other securities and property
deliverable upon exercise of this Warrant. Such notice shall also specify the
date as of which the holders of the Common Stock of record shall be entitled to
exchange their Common Stock for securities or other property deliverable upon
such reorganization, reclassification, sale, consolidation, merger, dissolution,
liquidation or winding up, as the case may be.

Warrants in the form of this Warrant with appropriate changes to reflect the

         7.       Lost, Mutilated or Missing Warrant.

theft, destruction or mutilation of this Warrant, and upon surrender and

         10.      Miscellaneous.

         stock, $.01 par value per share) and stock of any other class or other
         consideration into which such currently authorized Common Stock may
         hereafter have been changed.

                  (b) This Warrant shall be construed in accordance with and
         governed by the laws of the State of New York without regard to
         principles of conflicts and choice of laws.

Warrant No. 34                                  For the Purchase of 9,174 Shares


                               LASERTECHNICS, INC.

                          COMMON STOCK PURCHASE WARRANT

                  THIS CERTIFIES THAT, for value received, Wolfensohn Associates
L.P. ("Wolfensohn") or its successors in interest, assigns or transferees
(collectively, the "Warrant Holder"), is entitled to subscribe for and purchase
from Lasertechnics, Inc., a Delaware corporation (the "Company"), 9,174 shares
of the Company's Common Stock (as defined in paragraph 10 hereof) (the "Warrant
Shares") at the "Exercise Price" (as hereinafter defined) per share, as the
number of Warrant Shares and the Exercise Price shall be adjusted and readjusted
or changed from time to time in accordance with paragraph 4 hereof. The Exercise
Price shall be the lesser of (i) $2.18 or (ii) if the Company completes an
equity financing of Five Million Dollars ($5,000,000) or more, on or before
December 31, 1996, the price per share at which shares of Common Stock are
issued in such financing or if such financing involves convertible or
exchangeable securities, the price at which such securities may be converted
into or exchanged for Common Stock.

                  This Warrant may be exercised at any time and from time to
time on or prior to December 31, 2001.

         1.       Exercise of Warrant.

         The rights represented by this Warrant may be exercised by the Warrant
Holder, in whole or in part, by (a) delivering to the Company a duly executed
notice of exercise in the form of Annex A hereto and (b) at the Warrant Holder's
option, either (i) delivering a check payable to (or wire transfer to the
account of) the Company in an amount equal to the product of (x) the Exercise
Price times (y) the number of Warrant Shares as to which this Warrant is being
exercised
<PAGE>   2
(such product, the "Total Exercise Price") or (ii) delivering to the Company a
letter (the "Conversion Letter") requesting conversion or exchange of a portion
of any indebtedness owed by the Company to the Warrant Holder in an amount equal
to the Total Exercise Price or (iii) surrendering to the Company a portion of
this Warrant with a "Value" (as defined below) equal to the Total Exercise
Price. For the purpose of clause (b) (iii) above, "Value" shall mean the product
of (I) the amount by which the average of the closing prices of the Company's
Common Stock on the thirty trading days preceding the date of exercise, as
reported in The Wall Street Journal, exceeds the Exercise Price and (II) the
number of Warrant Shares as to which this Warrant is surrendered for the purpose
of effecting payment for Warrant Shares. This Warrant shall be deemed to have
been exercised immediately prior to the close of business on the date of
delivery of a duly executed notice of exercise, together with the amount (in
cash or by delivering the Conversion Letter or by surrender of a portion of this
Warrant) payable upon exercise of this Warrant and, as of such moment, (i) the
rights of the Warrant Holder, as such, with respect to the number of Warrant
Shares as to which this Warrant is being exercised (and, if applicable,
surrendered as payment of the Total Exercise Price) shall cease, and (ii) such
Warrant Holder shall be deemed to be the record holder of the shares of Common
Stock issuable upon such exercise. As soon as practicable after the exercise, in
whole or in part, of this Warrant, and in any event within 5 business days
thereafter, the Company at its expense (including the payment by it of any
applicable issuance or stamp taxes) will cause to be issued in the name of and
delivered to the Warrant Holder, or as the Warrant Holder (upon payment by the
Warrant Holder of any applicable transfer taxes) may direct, a certificate of
certificates for the number of fully paid and nonassessable shares of Common
Stock to which the Warrant Holder shall be entitled upon such exercise. In the
event of partial exercise of this Warrant and, if applicable, partial surrender
of this Warrant pursuant to clause (b) (iii) of this paragraph, the Warrant need
not be delivered to the Company provided that the Warrant Holder agrees to make
a notation of such partial exercise and, if applicable, surrender on the
Warrant. If this Warrant is delivered to the Company, the Company shall issue
and deliver to the Warrant Holder a new Warrant evidencing the rights to
purchase the remaining Warrant Shares, which new Warrant shall in all other
respects be identical to this Warrant.

         2.       Investment Representation.

         The Warrant Holder by accepting this Warrant represents that the
Warrant Holder is acquiring this Warrant for its own account or the account of
an affiliate for investment purposes and not with the view to any offering or
distribution and that the Warrant Holder will not sell or otherwise dispose of
this Warrant or the underlying Warrant Shares in violation of applicable
securities laws. The Warrant Holder acknowledges that the certificates
representing any Warrant Shares will bear a legend indicating that they have not
been registered under the Act, and may not be sold by the Warrant Holder except
pursuant to an effective registration or pursuant to an exemption from
registration. Wolfensohn shall be entitled to include the Warrant Shares in any


                                       2
<PAGE>   3
demand or piggyback registration to which Wolfensohn is entitled in respect of
Common Stock held by it.

         3.       Validity of Warrant and Issue of Shares.

         The Company represents and warrants that this Warrant has been duly
authorized and validly issued and warrants and agrees that all shares of Common
Stock that may be issued upon the exercise of the rights represented by this
Warrant will, when issued upon such exercise, be duly authorized, validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issue thereof. The Company further warrants and agrees that
during the period within which the rights represented by this Warrant may be
exercised, the Company will at all times have authorized and reserved a
sufficient number of shares of Common Stock to provide for the exercise of the
rights represented by this Warrant.

         4.       Antidilution Provisions.

         The terms of this Warrant shall be subject to adjustment as follows:

         (a) In case the Company shall (i) pay a stock dividend or make a
distribution to holders of Common Stock in shares 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, or (iv) issue by
reclassification of its shares of Common Stock any shares of capital stock of
the Company, (A) the Exercise Price shall be increased or decreased, as the case
may be, to an amount which shall bear the same relation to the Exercise Price in
effect immediately prior to such action as the total number of shares
outstanding immediately prior to such action shall bear to the total number of
shares outstanding immediately after such action and (B) this Warrant
automatically shall be adjusted so that it shall thereafter evidence the right
to purchase the kind and number of Warrant Shares or other securities which the
Warrant Holder would have owned and would have been entitled to receive after
such action if this Warrant had been exercised immediately prior to such action
or any record date with respect thereto. An adjustment made pursuant to this
subparagraph (a) shall become effective retroactively immediately after the
record date in the case of a dividend or distribution of Common Stock and shall
become effective immediately after the effective date in the case of a
subdivision, combination or reclassification.

         (b) In case the Company shall fix a record date for the making of a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of (i) assets (other than cash dividends or cash
distributions payable out of consolidated net income or retained earnings or
dividends payable in Common Stock), (ii) evidences of indebtedness or other debt
or equity securities of the Company, or of any corporation other than the
Company (except for the


                                       3
<PAGE>   4
Common Stock of the Company) or (iii) subscription rights, options or warrants
to purchase any of the foregoing assets or securities, whether or not such
rights, options or warrants are immediately exercisable (hereinafter
collectively called "Distributions on Common Stock"), the Company shall make
provisions for the Warrant Holder to receive upon exercise of this Warrant, a
proportional amount (depending upon the extent to which this Warrant is
exercised) of such assets, evidences of indebtedness, securities or such other
rights, as if such Warrant Holder had exercised this Warrant on or before such
record date.

         (c) In case of any consolidation or merger of the Company with or into
another corporation or the sale of all or substantially all of the assets of the
Company to another corporation, this Warrant thereafter shall be exercisable for
the kind and amount of shares of stock or other securities or property to which
a holder of the number of shares of Common Stock of the Company deliverable upon
exercise of this Warrant would have been entitled upon such consolidation,
merger or sale; and, in such case, appropriate adjustment shall be made in the
application of the provisions in this paragraph 4, to the end that the
provisions set forth in this paragraph 4 (including provisions with respect to
changes in and adjustments of the exercise price) shall thereafter be
applicable, as nearly as reasonably may be, in relation to any shares of stock
or other securities or property thereafter deliverable upon the exercise of this
Warrant.

         (d) If any event shall occur as to which the provisions of this
paragraph 4 shall not be strictly applicable, but with respect to which the
failure to make any adjustment to the Exercise Price and the number of Warrant
Shares issuable upon exercise of this Warrant would not fairly protect the
purchase rights represented by this Warrant in accordance with the intent and
principles of this paragraph 4, upon request of the Warrant Holder, the Company
shall appoint a firm of independent public accountants reasonably acceptable to
the Warrant Holder which shall give its opinion upon the adjustments, if any,
consistent with the intent and principles established in this paragraph 4
necessary to preserve without dilution the purchase rights represented by this
Warrant. Upon receipt of such opinion, the Company will promptly mail a copy
thereof to the Warrant Holder and shall make the adjustments described therein.

         (e) Upon the occurrence of each adjustment or readjustment of the
exercise price or any change in the number of Warrant Shares or in the shares of
stock or other securities or property deliverable upon exercise of this Warrant
pursuant to this paragraph 4, the Company at its expense shall promptly compute
such adjustment or readjustment and change in accordance with the terms hereof
and furnish to each holder hereof a certificate signed by the chief financial
officer of the Company, setting forth such adjustment or readjustment and change
and showing in detail the facts upon which such adjustment or readjustment and
change is based. The Company shall, upon the written request at any time of the
Warrant Holder, furnish or cause to be furnished to such Holder, a similar
certificate setting forth (i) such adjustment or readjustment and change, (ii)

                             SENIOR PROMISSORY NOTE


                                                                   June 25, 1997

         LASERTECHNICS, INC., a Delaware corporation having its principal place
of business in Carrollton, Texas (the "Company"), for value received, hereby
promises to pay to the order of Wolfensohn Partners L.P., a Delaware limited
partnership, or its transferees or assigns (the "Holder"), on December 31, 1997
(the "Final Maturity Date"), the unpaid principal amount of all advances made by
the Holder to the Company hereunder ("Advances"), as recorded on the grid below,
including any additional pages (the "Grid"), together with interest thereon from
the date of such Advance recorded on the Grid, at the rate of ten percent (10%)
per annum, calculated on the basis of the actual number of days elapsed over a
364- (or 365-) day year (the "Base Interest Rate"). Each payment received by the
Holder hereunder shall be applied to Advances in reverse of the order in which
such Advances were made, and each such payment shall be applied first to the
interest accrued on and then to the unpaid principal amount of the applicable
Advance. This Note is one of the Senior Promissory Notes ("Notes") issued and
sold by the Company under the Note Purchase Agreement dated as of June 25, 1997
(the "Note Purchase Agreement"), among the Company, the initial Holder and the
other purchaser named therein, and the Holder shall be entitled to the benefits
of any collateral security provided for therein for the benefit of Holders of
Senior Notes.

         Payment of principal and interest shall be made in such coin or
currency of the United States of America as at the time of payment shall be
legal tender for the payment of public and private debts. All such payments
shall be paid by wire transfer of Federal funds in accordance with the written
instructions of the Holder or, in the absence of such instructions, by check
mailed to the Holder at the address last given to the Company by the Holder in
writing for such purpose.

         This Note may be prepaid in whole or in part at any time at the option
of the Company, without premium or penalty, upon not less than 20 days' prior
written notice to the Holder.


                                   Page 1 of 3
<PAGE>   2
         If any time after the date hereof the Company or any subsidiary
completes (i) an equity or long-term debt financing, (ii) a sale of assets
outside the ordinary course of business, (iii) a sale-leaseback or similar
financing, or (iv) a joint venture or other strategic partnership (any such
transaction, an "Extraordinary Transaction"), and such Extraordinary Transaction
results in cash proceeds to the Company (together with the cash proceeds of any
other Extraordinary Transaction after the date hereof, to the extent not
previously applied) in excess of $ 1,000,000 (such excess, the "Available Cash
Proceeds"), then the full amount of Available Cash Proceeds shall be applied to
prepay this Note as provided herein; provided, however, that if the Available
Cash Proceeds are not sufficient to pay in full the principal of, and accrued
interest on, this Note and all other Notes issued under the Note Purchase
Agreement, then the Available Cash Proceeds shall be applied to prepay this Note
and all other Notes issued under the Note Purchase Agreement on a pro rata
basis, in proportion to the respective aggregate unpaid principal amounts
thereof.

         The Company hereby waives presentment for payment, demand for payment,
notice of nonpayment, protest and notice of protest.

         This Note may be prepaid in whole or in part (in amounts not less than
$50,000) at any time at the option of the Company, upon not less than 20 days'
prior written notice to the Holder, without premium or penalty; provided,
however, that any amounts prepaid hereunder or under any of the other Notes
shall be applied to prepay this Note and all other Notes issued under the Note
Purchase Agreement on a pro rata basis, in proportion to the respective
aggregate unpaid principal amounts thereof.

         This Note shall be binding upon the Company and its successors and
assigns and shall inure to the benefit of the Holder and its successors, assigns
and transferees.

         If the Company fails to pay any amount of principal or interest when
due, the entire unpaid principal of and accrued interest on all Advances shall
forthwith become absolutely due and payable without any notice, demand, protest
or presentment whatsoever, all of which are hereby expressly waived. Interest on
any past due principal amount, whether at the Final Maturity Date or by
acceleration, shall accrue at a rate equal to the Base Interest Rate plus five
percent (5%) per annum, but in no event higher than the maximum legal rate of
interest permitted under applicable law. In addition, if any amount payable
hereunder shall remain unpaid after 3:00 p.m., New York City time, on the Final
Maturity Date, the Company shall pay to the record Holder of this Note at such
time the Additional Consideration provided for in the Note Purchase Agreement
(as such term is defined therein). The Company shall pay to the Holder all costs
and expenses of collection and enforcement relating to this Note, including
without limitation reasonable attorneys' fees and expenses.

         This Note shall be governed by and construed in accordance with the
laws of the State of New York, without reference to its rules as to conflicts of
law. Any judicial proceeding brought against the Company to enforce, or
otherwise in connection with, this Note may be brought in any court of competent
jurisdiction in the City of New York, and, by execution and delivery of this
Note, the Company (i) accepts, generally and unconditionally, the nonexclusive
jurisdiction of such courts and any related appellate court and irrevocably
agrees to be bound by any final judgment rendered thereby in connection with
this Note and (ii) irrevocably waives any objection it may now or hereafter have
as to the venue of any such proceeding brought in such a court or that such a
court is an inconvenient forum.

         THE COMPANY HEREBY UNCONDITIONALLY AND IRREVOCABLY WAIVES TRIAL BY JURY
IN ANY ACTION, SUIT, COUNTERCLAIM OR CROSS CLAIM ARISING OUT OF OR IN CONNECTION
WITH THIS NOTE.

         IN WITNESS WHEREOF, the Company has caused this Note to be signed by
its Vice President and has caused its corporate seal to be affixed and attested
by its Secretary.

                                  Page 1 of 10
<PAGE>   2
product of (I) the amount by which the average closing price per share of the
Company's Common Stock over the ten trading days preceding the date of exercise,
as reported in The Wall Street Journal, exceeds the Exercise Price and (II) the
number of Warrant Shares as to which this Warrant is surrendered for the purpose
of effecting payment for Warrant Shares. This Warrant shall be deemed to have
been exercised immediately prior to the close of business on the date of
delivery of a duly executed notice of exercise, together with the amount (in
cash or by delivering the Conversion Letter or by surrender of a portion of this
Warrant) payable upon exercise of this Warrant and, as of such moment, (i) the
rights of the Warrant Holder, as such, with respect to the number of Warrant
Shares as to which this Warrant is being exercised (and, if applicable,
surrendered as payment of the Total Exercise Price) shall cease, and (ii) such
Warrant Holder shall be deemed to be the record holder of the shares of Common
Stock issuable upon such exercise. As soon as practicable after the exercise, in
whole or in part, of this Warrant, and in any event within 5 business days
thereafter, the Company at its expense (including the payment by it of any
applicable issuance or stamp taxes) will cause to be issued in the name of and
delivered to the Warrant Holder, or as the Warrant Holder (upon payment by the
Warrant Holer of any applicable transfer taxes) may direct, a certificate or
certificates for the number of fully paid and nonassessable shares of Common
Stock to which the Warrant Holder shall be entitled upon such exercise. In the
event of partial exercise of this Warrant and, if applicable, partial surrender
of this Warrant pursuant to clause (b)(iii) of this paragraph, the Warrant need
not be delivered to the Company provided that the Warrant Holder agrees to make
a notation of such partial exercise and, if applicable, surrender on the
Warrant. If this Warrant is delivered to the Company, the Company shall issue
and deliver to the Warrant Holder a new Warrant evidencing the rights to
purchase the remaining Warrant Shares, which new Warrant shall in all other
respects be identical to this Warrant.

         2.       Investment Representation.

         The Warrant Holder by accepting this Warrant represents that the
Warrant Holder is acquiring this Warrant for its own account or the account of
an affiliate for investment purposes and not with the view to any offering or
distribution and that the Warrant Holder will not sell or otherwise dispose of
this Warrant or the underlying Warrant Shares in violation of applicable
securities laws. The Warrant Holder acknowledges that the certificates
representing any Warrant Shares will bear a legend indicating that they have not
been registered under the Act, and may not be sold by the Warrant Holder except
pursuant to an effective registration or pursuant to an exemption from
registration. The Warrant Holder shall be entitled to include the Warrant Shares
in any demand or piggyback registration to which Warrant Holder is otherwise
entitled in respect of Common Stock held by it, in accordance with (and subject
to) the terms and conditions of any agreement between the Company and the
Warrant Holder with respect to such registration rights.

         3.       Validity of Warrant and Issue of Shares.

         The Company represents and warrants that this Warrant has been duly
authorized and validly issued and covenants and agrees that all shares of Common
Stock that may be issued upon the exercise of the rights represented by this
Warrant will, when issued upon such exercise, be duly authorized, validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issue thereof. The Company further covenants and agrees that
during the period within which the rights represented by this Warrant may be
exercised, the Company will at all times have authorized and reserved a
sufficient number of shares of Common Stock to provide for the exercise of the
rights represented by this Warrant.

         4.       Antidilution Provisions.

         The terms of this Warrant shall be subject to adjustment as follows:

         (a) If the Company shall (i) pay a stock dividend or make a
distribution to holders of Common Stock in shares 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, or (iv) issue by
reclassification of its shares of Common Stock any shares of capital stock of
the Company, (A) the Exercise Price shall be increased or decreased, as the case
may be, to an amount which shall bear the same relation to the Exercise Price in
effect immediately prior to such action as the total number of shares
outstanding immediately prior to such action shall bear to the total number of
shares outstanding immediately after such action and (B) this Warrant
automatically shall be adjusted so that it shall thereafter evidence the right
to purchase the kind and number of Warrant Shares or other securities which the
Warrant Holder would have owned and would have been entitled to receive after
such action if this Warrant had been exercised immediately prior to such action
or any record date with respect thereto. An adjustment made pursuant to this
subparagraph (a) shall become effective retroactively immediately after the
record date in the case of a dividend or distribution of Common Stock and shall
become effective immediately after the effective date in the case of a
subdivision, combination or reclassification.

         (b) If the Company shall fix a record date for the making of a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of (i) assets (other than cash dividends or cash
distributions payable out of consolidated net income or retained earnings or
dividends payable in Common Stock), (ii) evidences of indebtedness or other debt
or equity securities of the Company, or of any corporation other than the
Company (except for the Common Stock of the Company) or (iii) subscription
rights, options or warrants to purchase any of the foregoing assets or
securities, whether or not such rights, options or warrants are immediately
exercisable (hereinafter collectively called "Distributions on Common Stock"),
the Company shall


                                  Page 3 of 10
<PAGE>   4
make provisions for the Warrant Holder to receive upon exercise of this Warrant,
a proportional amount (depending upon the extent to which this Warrant is
exercised) of such assets, evidences of indebtedness, securities or such other
rights, as if such Warrant Holder had exercised this Warrant on or before such
record date.

         (c) In the case of any consolidation or merger of the Company with or
into another corporation or the sale of all or substantially all the assets of
the Company to another person or entity, this Warrant thereafter shall be
exercisable for the kind and amount of shares of stock or other securities or
property to which a holder of the number of shares of Common Stock of the
Company deliverable upon exercise of this Warrant would have been entitled upon
such consolidation, merger or sale; and, in such case, appropriate adjustment
shall be made in the application of the provisions in this paragraph 4, to the
end that the provisions set forth in this paragraph 4 (including provisions with
respect to changes in and adjustments of the exercise price) shall thereafter be
applicable, as nearly as reasonably may be, in relation to any shares of stock
or other securities or property thereafter deliverable upon the exercise of this
Warrant.

         (d) Upon the occurrence of each adjustment or readjustment of the
exercise price or any change in the number of Warrant Shares or in the shares of
stock or other securities or property deliverable upon exercise of this Warrant
pursuant to this paragraph 4, the Company at its expense shall promptly compute
such adjustment or readjustment and change in accordance with the terms hereof
and furnish to each holder hereof a certificate signed by the chief financial
officer of the Company, setting forth such adjustment or readjustment and change
and showing in detail the facts upon which such adjustment or readjustment and
change is based. The Company shall, upon the written request at any time of the
Warrant Holder, furnish or cause to be furnished to such Holder, a similar
certificate setting forth (i) such adjustment or readjustment and change, (ii)
the Exercise Price then in effect, and (iii) the number of Warrant Shares and
the amount, if any, of other shares of stock and other securities and property
which would be received upon the exercise of the Warrant.

         (e) The Company shall not be required upon the exercise of this Warrant
to issue any fraction of shares, but shall make any adjustment therefor by
rounding the number of shares obtainable upon exercise to the next highest whole
number of shares.

         5.       Transfer of Rights.

         This Warrant is transferable in whole or in part, at the option of the
Warrant Holder upon delivery of the Warrant Assignment Form annexed as Annex B
hereto, duly executed. The Company shall execute and deliver a new Warrant or
Warrants in the form of this Warrant with appropriate changes to reflect the
issuance of subsequent Warrants, in the name of the assignee or assignees named
in such instrument of assignment and, if the Warrant Holder's entire interest


                                  Page 4 of 10
<PAGE>   5
is not being transferred or assigned, in the name of the Warrant Holder, and
this Warrant shall promptly be canceled. Any transfer or exchange of this
Warrant shall be without charge to the Warrant Holder and any new Warrant or
Warrants issued shall be dated the date hereof. The term "Warrant" as used
herein includes any Warrants into which this Warrant may be divided or for which
it may be exchanged. The Warrant Holder (and not the Company) will be
responsible for any stamp, transfer or other taxes payable on any such transfer.

         6.       Lost, Mutilated or Missing Warrant.

         Upon receipt by the Company of evidence satisfactory to it of the loss,
theft, destruction or mutilation of this Warrant, and upon surrender and
cancellation of this Warrant, if mutilated, the Company shall execute and
deliver a new Warrant of like denomination and date.

         7.       Rights of Warrant Holder.

         The Warrant Holder shall not, by virtue hereof, be entitled to any
voting or other rights of a shareholder of the Company, either at law or equity,
and the rights of the Warrant Holder are limited to those expressed in this
Warrant.

         8.       Successors.

         All the provisions of this Warrant by or for the benefit of the Company
or the Warrant Holder shall bind and inure to the benefit of their respective
successors and assigns.

         9.       Miscellaneous.

         (a) As used herein, the term "Common Stock" shall mean and include the
Company's currently authorized common stock, $.01 par value per share, and stock
of any other class or other consideration into which such currently authorized
Common Stock may hereafter have been changed.

         (b) This Warrant shall be construed in accordance with and governed by
the laws of the State of Delaware.

         (c) The caption headings used in this Warrant are for convenience of
reference only and shall not be construed in any way to affect the
interpretation of any provisions of this Warrant.

         10.      Notices.

         Any notice pursuant to this Warrant shall be effective if sent by

SECURITIES LAWS. NEITHER THIS WARRANT NOR ANY SUCH SHARES MAY BE SOLD, OFFERED

WARRANT NO. F-8                                FOR THE PURCHASE OF 90,000 SHARES


                               LASERTECHNICS, INC.

                          COMMON STOCK PURCHASE WARRANT


         THIS CERTIFIES THAT, for value received, Wolfensohn Partners L.P. or
its successors in interest, assigns or transferees (collectively, the "Warrant
Holder"), is entitled to purchase from Lasertechnics, Inc., a Delaware
corporation (the "Company"), 90,000 shares of the Company's Common Stock (as
defined in paragraph 9(a) hereof) (the "Warrant Shares") at the exercise price
of ONE DOLLAR ($1.00) per share ("Exercise Price"). The number of Warrant Shares
and the Exercise Price shall be adjusted and readjusted or changed from time to
time in accordance with paragraph 4 hereof.

         This Warrant may be exercised at any time and from time to time on or
prior to July 14, 2002.

         1.       Exercise of Warrant.

         The rights represented by this Warrant may be exercised by the Warrant
Holder, in whole or in part, by (a) delivering to the Company a duly executed
notice of exercise in the form of Annex A hereto and (b) delivering a check
payable to (or wire transfer to the account of) the Company in an amount equal
to the product of (x) the Exercise Price times (y) the number of Warrant Shares
as to which this Warrant is being exercised (such product, the "Total Exercise
Price"). This Warrant shall be deemed to have been exercised immediately prior
to the close of business on the date of delivery of a duly executed notice of
exercise, together with the amount payable upon exercise of this Warrant and, as
of such moment, (i) the rights of the Warrant Holder, as such, with respect to
the number of Warrant Shares as to which this Warrant is being exercised shall
cease, and (ii) such Warrant Holder shall be deemed to be the record holder of
the
<PAGE>   2
shares of Common Stock issuable upon such exercise. As soon as practicable after
the exercise, in whole or in part, of this Warrant, and in any event within 5
business days thereafter, the Company at its expense (including the payment by
it of any applicable issuance or stamp taxes) will cause to be issued in the
name of and delivered to the Warrant Holder, or as the Warrant Holder (upon
payment by the Warrant Holder of any applicable transfer taxes) may direct, a
certificate or certificates for the number of fully paid and nonassessable
shares of Common Stock to which the Warrant Holder shall be entitled upon such
exercise. In the event of partial exercise of this Warrant, the Warrant need not
be delivered to the Company provided that the Warrant Holder agrees to make a
notation of such partial exercise on the Warrant. If this Warrant is delivered
to the Company, the Company shall issue and deliver to the Warrant Holder a new
Warrant evidencing the rights to purchase the remaining Warrant Shares, which
new Warrant shall in all other respects be identical to this Warrant.

         2.       Investment Representation.

         The Warrant Holder by accepting this Warrant represents that the
Warrant Holder is acquiring this Warrant for its own account or the account of
an affiliate for investment purposes and not with the view to any offering or
distribution and that the Warrant Holder will not sell or otherwise dispose of
this Warrant or the underlying Warrant Shares in violation of applicable
securities laws. The Warrant Holder acknowledges that, until such time as the
Warrant Shares are registered under the Act or resold pursuant to Rule 144
thereunder, the certificates representing any Warrant Shares will bear a legend
indicating that they have not been registered under the Act, and may not be sold
by the Warrant Holder except pursuant to an effective registration or pursuant
to an exemption from registration. The Warrant Holder shall be entitled to
include the Warrant Shares in any demand or piggyback registration to which the
Warrant Holder is entitled in respect of Common Stock held by it under the
Registration Rights Agreement dated as of July 29, 1996, among the Company, the
initial holder of this Warrant and the other parties thereto (the "Registration
Rights Agreement") (provided that such registration is on a form that permits
the resale of the Warrant Shares by the Warrant Holder to be registered
thereunder), to the same extent as if the Warrant Shares were included in the
definition of Registrable Securities set forth therein.

         3.       Validity of Warrant and Issue of Shares.

         The Company represents and warrants that this Warrant has been duly
authorized and validly issued and warrants and agrees that all shares of Common
Stock that may be issued upon the exercise of the rights represented by this
Warrant will, when issued upon such exercise, be duly authorized, validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issue thereof. The Company further warrants and agrees that
dining the period within which the rights represented by this Warrant may be
exercised, the Company


                                  Page 2 of 9
<PAGE>   3
will at all times have authorized and reserved a sufficient number of shares of
Common Stock to provide for the exercise of the rights represented by this
Warrant.

         4.       Antidilution Provisions.

         The terms of this Warrant shall be subject to adjustment as follows:

         (a) In case the Company shall (i) pay a stock dividend or make a
distribution to holders of Common Stock in shares 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, or (iv) issue by
reclassification of its shares of Common Stock any shares of capital stock of
the Company, (A) the Exercise Price shall be increased or decreased, as the case
may be, to an amount which shall bear the same relation to the Exercise Price in
effect immediately prior to such action as the total number of shares
outstanding immediately prior to such action shall bear to the total number of
shares outstanding immediately after such action and (B) this Warrant
automatically shall be adjusted so that it shall thereafter evidence the right
to purchase the kind and number of Warrant Shares or other securities which the
Warrant Holder would have been entitled to receive after such action if this
Warrant had been exercised immediately prior to such action or any record date
with respect thereto. An adjustment made pursuant to this subparagraph (a) shall
become effective retroactively immediately after the record date in the case of
a dividend or distribution of Common Stock and shall become effective
immediately after the effective date in the case of a subdivision, combination
or reclassification.

         (b) In case the Company shall fix a record date for the making of a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of (i) assets (other than cash dividends or cash
distributions payable out of consolidated net income or retained earnings or
dividends payable in Common Stock), (ii) evidences of indebtedness or other debt
or equity securities of the Company, or of any corporation other than the
Company (except for the Common Stock of the Company) or (iii) subscription
rights, options or warrants to purchase any of the foregoing assets or
securities, whether or not such rights, options or warrants are immediately
exercisable (hereinafter collectively called "Distributions on Common Stock"),
the Company shall make provisions for the Warrant Holder to receive upon
exercise of this Warrant, a proportional amount (depending upon the extent to
which this Warrant is exercised) of such assets, evidences of indebtedness,
securities or such other rights, as if such Warrant Holder had exercised this
Warrant on or before such record date.

         (c) In case of any consolidation or merger of the Company with or into
another corporation or the sale of all or substantially all of the assets of the
Company to another corporation, this Warrant thereafter shall be exercisable for
the kind and amount of shares of stock


                                  Page 3 of 9
<PAGE>   4
or other securities or property to which a holder of the number of shares of
Common Stock of the Company deliverable upon exercise of this Warrant would have
been entitled upon such consolidation, merger or sale; and, in such case,

WARRANT NO. 3                                  FOR THE PURCHASE OF 60,000 SHARES

                               LASERTECHNICS, INC.

                          COMMON STOCK PURCHASE WARRANT


           THIS CERTIFIES THAT, for value received, Wolfensohn Associates II
L.P. or its successors in interest, assigns or transferees (collectively, the
"Warrant Holder"), is entitled to purchase from Lasertechnics, Inc., a Delaware
corporation (the "Company"), 60,000 shares of the Company's Common Stock (as
defined in paragraph 9(a) hereof) (the "Warrant Shares") at the exercise price
of SEVENTY CENTS ($.70) per share ("Exercise Price"). The number of Warrant
Shares and the Exercise Price shall be adjusted and readjusted or changed from
time to time in accordance with paragraph 4 hereof.

      This Warrant may be exercised at any time and from time to time on or
prior to the third anniversary of the date of issuance set forth on the
signature page of this Warrant.

      1.   Exercise of Warrant.

      The rights represented by this Warrant may be exercised by the Warrant
Holder, in whole or in part, by (a) delivering to the Company a duly executed
notice of exercise in the form of Annex A hereto and (b) at the Warrant Holder's
option, either (i) delivering a check payable to (or wire transfer to the
account of) the Company in an amount equal to the product of (x) the Exercise
Price times (y) the number of Warrant Shares as to which this Warrant is being
exercised (such product, the "Total Exercise Price") or (ii) delivering to the
company a letter (the "Conversion Letter") requesting conversion or exchange of
a portion of any indebtedness owed by the Company to the Warrant Holder in an
amount equal to the Total Exercise Price or (iii) surrendering to the Company a
portion of this Warrant with a "Value" (as defined below) equal to the Total
Exercise Price. For the purpose of clause (b)(iii) above, "Value" shall mean the
product of (I) the amount by which the average closing price per share of the
Company's Common Stock over the ten trading days preceding the date of exercise,
as reported in The Wall Street Journal, exceeds the Exercise Price and (II) the
number of Warrant Shares as to which this Warrant is surrendered for the purpose
of effecting payment for Warrant Shares. This Warrant shall be deemed to have
been


                                       1
<PAGE>   2
exercised immediately prior to the close of business on the date of delivery of
a duly executed notice of exercise, together with the amount (in cash or by
delivering the Conversion Letter or by surrender of a portion of this Warrant)
payable upon exercise of this Warrant and, as of such moment, (i) the rights of
the Warrant Holder, as such, with respect to the number of Warrant Shares as to
which this Warrant is being exercised (and, if applicable, surrendered as
payment of the Total Exercise Price) shall cease, and (ii) such Warrant Holder
shall be deemed to be the record holder of the shares of Common Stock issuable
upon such exercise. As soon as practicable after the exercise, in whole or in
part, of this Warrant, and in any event within 5 business days thereafter, the
Company at its expense (including the payment by it of any applicable issuance
or stamp taxes) will cause to be issued in the name of and delivered to the
Warrant Holder, or as the Warrant Holder (upon payment by the Warrant Holder of
any applicable transfer taxes) may direct, a certificate or certificates for the
number of fully paid and nonassessable shares of Common Stock to which the
Warrant Holder shall be entitled upon such exercise. In the event of partial
exercise of this Warrant and, if applicable, partial surrender of this Warrant
pursuant to clause (b)(iii) of this paragraph, the Warrant need not be delivered
to the Company provided that the Warrant Holder agrees to make a notation of
such partial exercise and, if applicable, surrender on the Warrant. If this
Warrant is delivered to the Company, the Company shall issue and deliver to the
Warrant Holder a new Warrant evidencing the rights to purchase the remaining
Warrant Shares, which new Warrant shall in all other respects be identical to
this Warrant.

      2.   Investment Representation.

      The Warrant Holder by accepting this Warrant represents that the Warrant
Holder is acquiring this Warrant for its own account or the account of an
affiliate for investment purposes and not with the view to any offering or
distribution and that the Warrant Holder will not sell or otherwise dispose of
this Warrant or the underlying Warrant Shares in violation of applicable
securities laws. The Warrant Holder acknowledges that the certificates
representing any Warrant Shares will bear a legend indicating that they have not
been registered under the Act, and may not be sold by the Warrant Holder except
pursuant to an effective registration or pursuant to an exemption from
registration. The Warrant Holder shall be entitled to include the Warrant Shares
in any demand or piggyback registration to which Warrant Holder is otherwise
entitled in respect of Common Stock held by it, in accordance with (and subject
to) the terms and conditions of any agreement between the Company and the
Warrant Holder with respect to such registration rights.

      3.   Validity of Warrant and Issue of Shares.

      The Company represents and warrants that this Warrant has been duly
authorized and validly issued and covenants and agrees that all shares of Common
Stock that may be issued upon the exercise of the rights represented by this
Warrant will, when issued upon such exercise, be duly authorized, validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issue thereof. The Company further covenants and agrees that
during the period within which the rights represented by this Warrant may be
exercised, the Company will


                                       2
<PAGE>   3
at all times have authorized and reserved a sufficient number of shares of
Common Stock to provide for the exercise of the rights represented by this
Warrant.

      4.   Antidilution Provisions.

      The terms of this Warrant shall be subject to adjustment as follows:

      (a) If the Company shall (i) pay a stock dividend or make a distribution
to holders of Common Stock in shares 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, or (iv) issue by reclassification
of its shares of Common Stock any shares of capital stock of the Company, (A)
the Exercise Price shall be increased or decreased, as the case may be, to an
amount which shall bear the same relation to the Exercise Price in effect
immediately prior to such action as the total number of shares outstanding
immediately prior to such action shall bear to the total number of shares
outstanding immediately after such action and (B) this Warrant automatically
shall be adjusted so that it shall thereafter evidence the right to purchase the
kind and number of Warrant Shares or other securities which the Warrant Holder
would have owned and would have been entitled to receive after such action if
this Warrant had been exercised immediately prior to such action or any record
date with respect thereto. An adjustment made pursuant to this subparagraph (a)
shall become effective retroactively immediately after the record date in the
case of a dividend or distribution of Common Stock and shall become effective
immediately after the effective date in the case of a subdivision, combination
or reclassification.

      (b) If the Company shall fix a record date for the making of a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of (i) assets (other than cash dividends or cash
distributions payable out of consolidated net income or retained earnings or
dividends payable in Common Stock), (ii) evidences of indebtedness or other debt
or equity securities of the Company, or of any corporation other than the
Company (except for the Common Stock of the Company) or (iii) subscription
rights, options or warrants to purchase any of the foregoing assets or
securities, whether or not such rights, options or warrants are immediately
exercisable (hereinafter collectively called "Distributions on Common Stock"),
the Company shall make provisions for the Warrant Holder to receive upon
exercise of this Warrant, a proportional amount (depending upon the extent to
which this Warrant is exercised) of such assets, evidences of indebtedness,
securities or such other rights, as if such Warrant Holder had exercised this
Warrant on or before such record date.

      (c) In the case of any consolidation or merger of the Company with or into
another corporation or the sale of all or substantially all the assets of the
Company to another person or entity, this Warrant thereafter shall be
exercisable for the kind and amount of shares of stock or other securities or
property to which a holder of the number of shares of Common Stock of the
Company deliverable upon exercise of this Warrant would have been entitled upon
such


                                       3
<PAGE>   4
consolidation, merger or sale; and, in such case, appropriate adjustment shall
be made in the application of the provisions in this paragraph 4, to the end
that the provisions set forth in this paragraph 4 (including provisions with
respect to changes in and adjustments of the exercise price) shall thereafter be
applicable, as nearly as reasonably may be, in relation to any shares of stock
or other securities or property thereafter deliverable upon the exercise of this
Warrant.

      (d) Upon the occurrence of each adjustment or readjustment of the exercise
price or any change in the number of Warrant Shares or in the shares of stock or
other securities or property deliverable upon exercise of this Warrant pursuant
to this paragraph 4, the Company at its expense shall promptly compute such
adjustment or readjustment and change in accordance with the terms hereof and
furnish to each holder hereof a certificate signed by the chief financial
officer of the Company, setting forth such adjustment or readjustment and change
and showing in detail the facts upon which such adjustment or readjustment and
change is based. The Company shall, upon the written request at any time of the
Warrant Holder, furnish or cause to be furnished to such Holder, a similar
certificate setting forth (i) such adjustment or readjustment and change, (ii)
the Exercise Price then in effect, and (iii) the number of Warrant Shares and
the amount. if any, of other shares of stock and other securities and property
which would be received upon the exercise of the Warrant.

      (e) The Company shall not be required upon the exercise of this Warrant to
issue any fraction of shares, but shall make any adjustment therefor by rounding
the number of shares obtainable upon exercise to the next highest whole number
of shares.

      5.   Transfer of Rights.

      This Warrant is transferable in whole or in part, at the option of the
Warrant Holder upon delivery of the Warrant Assignment Form annexed as Annex B
hereto, duly executed. The Company shall execute and deliver a new Warrant or
Warrants in the form of this Warrant with appropriate changes to reflect the
issuance of subsequent Warrants, in the name of the assignee or assignees named
in such instrument of assignment and, if the Warrant Holder's entire interest is
not being transferred or assigned, in the name of the Warrant Holder, and this
Warrant shall promptly be canceled. Any transfer or exchange of this Warrant
shall be without charge to the Warrant Holder and any new Warrant or Warrants
issued shall be dated the date hereof. The term "Warrant" as used herein
includes any Warrants into which this Warrant may be divided or for which it may
be exchanged. The Warrant Holder (and not the Company) will be responsible for
any stamp, transfer or other taxes payable on any such transfer.

      6.   Lost, Mutilated or Missing Warrant.

      Upon receipt by the Company of evidence satisfactory to it of the loss,
theft, destruction or mutilation of this Warrant, and upon surrender and
cancellation of this Warrant, if mutilated, the Company shall execute and

the laws of the State of Delaware.

BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") OR UNDER ANY STATE
SECURITIES LAWS. NEITHER THIS WARRANT NOR ANY SUCH SHARES MAY BE SOLD, OFFERED

                          COMMON STOCK PURCHASE WARRANT


       THIS CERTIFIES THAT, for value received, _______________________________
("___________________") or its successors in interest, assigns or transferees
(collectively, the "Warrant Holder"), is entitled to purchase from
Lasertechnics, Inc., a Delaware corporation (the "Company"), shares of the
Company's Common Stock (as defined in paragraph 9(a) hereof) (the "Warrant
Shares") at the exercise price of ONE DOLLAR ($1.00) per share ("Exercise
Price"). The number of Warrant Shares and the Exercise Price shall be adjusted
and readjusted or changed from time to time in accordance with paragraph 4
hereof.

       This Warrant may be exercised at any time and from time to time on or
prior to July 14, 2002.

       1. Exercise of Warrant.

       The rights represented by this Warrant may be exercised by the Warrant
Holder, in whole or in part, by (a) delivering to the Company a duly executed
notice of exercise in the form of Annex A hereto and (b) delivering a check
payable to (or wire transfer to the account of) the Company in an amount equal
to the product of (x) the Exercise Price times (y) the number of Warrant Shares
as to which this Warrant is being exercised (such product, the "Total Exercise
Price"). This Warrant shall be deemed to have been exercised immediately prior
to the close of business on the date of delivery of a duly executed notice of
exercise, together with the amount payable upon exercise of this Warrant and, as
of such moment, (i) the rights of the Warrant Holder, as such, with respect to
the number of Warrant Shares as to which this Warrant is being exercised shall
cease, and (ii) such Warrant Holder shall be deemed to be the record holder of
the shares of Common Stock issuable upon such exercise. As soon as practicable
after the exercise,
<PAGE>   9
in whole or in part, of this Warrant, and in any event within 5 business days
thereafter, the Company at its expense (including the payment by it of any
applicable issuance or stamp taxes) will cause to be issued in the name of and
delivered to the Warrant Holder, or as the Warrant Holder (upon payment by the
Warrant Holder of any applicable transfer taxes) may direct, a certificate or
certificates for the number of fully paid and nonassessable shares of Common
Stock to which the Warrant Holder shall be entitled upon such exercise. In the
event of partial exercise of this Warrant, the Warrant need not be delivered to
the Company provided that the Warrant Holder agrees to make a notation of such
partial exercise on the Warrant. If this Warrant is delivered to the Company,
the Company shall issue and deliver to the Warrant Holder a new Warrant
evidencing the rights to purchase the remaining Warrant Shares, which new
Warrant shall in all other respects be identical to this Warrant.

       2. Investment Representation.

       The Warrant Holder by accepting this Warrant represents that the Warrant
Holder is acquiring this Warrant for its own account or the account of an
affiliate for investment purposes and not with the view to any offering or
distribution and that the Warrant Holder will not sell or otherwise dispose of
this Warrant or the underlying Warrant Shares in violation of applicable
securities laws. The Warrant Holder acknowledges that, until such time as the
Warrant Shares are registered under the Act or resold pursuant to Rule 144
thereunder, the certificates representing any Warrant Shares will bear a legend
indicating that they have not been registered under the Act, and may not be sold
by the Warrant Holder except pursuant to an effective registration or pursuant
to an exemption from registration. The Warrant Holder shall be entitled to
include the Warrant Shares in any demand or piggyback registration to which the
Warrant Holder is entitled in respect of Common Stock held by it under the
Registration Rights Agreement dated as of [March 13, 1996] [July 29, 1996,]*
among the Company, the initial holder of this Warrant and the other parties
thereto (the "Registration Rights Agreement") (provided that such registration

with respect to the issue thereof. The Company further warrants and agrees that

will at all times have authorized and reserved a sufficient number of shares of
Common Stock to provide for the exercise of the rights represented by this
Warrant.

       4. Antidilution Provisions.

       The terms of this Warrant shall be subject to adjustment as follows:

       (a) In case the Company shall (i) pay a stock dividend or make a
distribution to holders of Common Stock in shares 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, or (iv) issue by
reclassification of its shares of Common Stock any shares of capital stock of
the Company, (A) the Exercise Price shall be increased or decreased, as the case
may be, to an amount which shall bear the same relation to the Exercise Price in
effect immediately prior to such action as the total number of shares
outstanding immediately prior to such action shall bear to the total number of
shares outstanding immediately after such action and (B) this Warrant
automatically shall be adjusted so that it shall thereafter evidence the right
to purchase the kind and number of Warrant Shares or other securities which the
Warrant Holder would have been entitled to receive after such action if this
Warrant had been exercised immediately prior to such action or any record date
with respect thereto. An adjustment made pursuant to this subparagraph (a) shall
become effective retroactively immediately after the record date in the case of
a dividend or distribution of Common Stock and shall become effective
immediately after the effective date in the case of a subdivision, combination
or reclassification.

       (b) In case the Company shall fix a record date for the making of a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of (i) assets (other than cash dividends or cash
distributions payable out of consolidated net income or retained earnings or
dividends payable in Common Stock), (ii) evidences of indebtedness or other debt
or equity securities of the Company, or of any corporation other than the
Company (except for the Common Stock of the Company) or (iii) subscription
rights, options or warrants to purchase any of the foregoing assets or
securities, whether or not such rights, options or warrants are immediately
exercisable (hereinafter collectively called "Distributions on Common Stock"),
the Company shall make provisions for the Warrant Holder to receive upon
exercise of this Warrant, a proportional amount (depending upon the extent to
which this Warrant is exercised) of such assets, evidences of indebtedness,
securities or such other rights, as if such Warrant Holder had exercised this
Warrant on or before such record date.

       (c) In case of any consolidation or merger of the Company with or into
another corporation or the sale of all or substantially all of the assets of the
Company to another corporation, this Warrant thereafter shall be exercisable for
the kind and amount of shares of stock or other securities or property to which
a holder of the number of shares of Common Stock of the Company deliverable upon
exercise of this Warrant would have been entitled upon such


                                  Page 3 of 9
<PAGE>   11
consolidation, merger or sale; and, in such case, appropriate adjustment shall
be made in the application of the provisions in this paragraph 4, to the end
that the provisions set forth in this paragraph 4 (including provisions with
respect to changes in and adjustments of the exercise price) shall thereafter be
applicable, as nearly as reasonably may be, in relation to any shares of stock
or other securities or property thereafter deliverable upon the exercise of this
Warrant.

       (d) Upon the occurrence of each adjustment or readjustment of the
exercise price or any change in the number of Warrant Shares or in the shares of
stock or other securities or property deliverable upon exercise of this Warrant
pursuant to this paragraph 4, the Company at its expense shall promptly compute
such adjustment or readjustment and change in accordance with the terms hereof
and furnish to each holder hereof a certificate signed by the chief financial
officer of the Company, setting forth such adjustment or readjustment and change
and showing in detail the facts upon which such adjustment or readjustment and
change is based. The Company shall, upon the written request at any time of the
Warrant Holder, furnish or cause to be furnished to such Holder, a similar
certificate setting forth (i) such adjustment or readjustment and change, (ii)
the Exercise Price then in effect, and (iii) the number of Warrant Shares and
the amount, if any, of other shares of stock and other securities and property
which would be received upon the exercise of the Warrant.

       (e) The Company shall not be required upon the exercise of this Warrant
to issue any fraction of shares, but shall make any adjustment therefor by
rounding the number of shares obtainable upon exercise to the next highest whole
number of shares.

       5. Transfer of Rights.

       This Warrant is transferable in whole or in part, at the option of the
Warrant Holder upon delivery of the Warrant Assignment Form annexed as Annex B
hereto, duly executed. The Company shall execute and deliver a new Warrant or
Warrants in the form of this Warrant with appropriate changes to reflect the
issuance of subsequent Warrants, in the name of the assignee or assignees named
in such instrument of assignment and, if the Warrant Holder's entire interest is
not being transferred or assigned, in the name of the Warrant Holder, and this
Warrant shall promptly be canceled. Any transfer or exchange of this Warrant
shall be without charge to the Warrant Holder and any new Warrant or Warrants
issued shall be dated the date hereof. The term "Warrant" as used herein
includes any Warrants into which this Warrant may be divided or for which it may
be exchanged. The Warrant Holder (and not the Company) will be responsible for
any stamp, transfer or other taxes payable on any such transfer.

       6. Lost, Mutilated or Missing Warrant.

       Upon receipt by the Company of evidence satisfactory to it of the loss,
theft, destruction or mutilation of this Warrant, and upon surrender and
cancellation of this Warrant, if mutilated, the Company shall execute and
deliver a new Warrant of like tenor, denomination and date.

Company's currently authorized common stock, $.01 par value per share, and stock
of any other class or other consideration into which such currently authorized
Common Stock may hereafter have been changed.

       (b) This Warrant shall be construed in accordance with and governed by
the laws of the State of Delaware.

       (c) The caption headings used in this Warrant are for convenience of
reference only and shall not be construed in any way to affect the
interpretation of any provisions of this Warrant.

first class mail, postage prepaid, or delivered by facsimile transmission,

                      ALLONGE TO 10% CONVERTIBLE DEBENTURE
                                DUE MARCH 1, 1999
                       ----------------------------------



            REFERENCE IS MADE to that certain 10% Convertible Debenture Due
March 1, 1999 (the "Debenture"), of LASERTECHNICS, INC., a Delaware corporation
(the "Company"), payable to _______________ or its registered assign (the
"Holder"). This Allonge amends the Debenture, effective as of the date first
written above: (i) to provide for certain limitations on the right of the Holder
to convert the Debenture during the Standstill Period (as defined herein) and
(ii) to reduce the Fixed Conversion Price (as defined in the Debenture) by
$1.00.

            NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, and intending to be bound hereby, the Company hereby covenants and
agrees with and for the benefit of the Holder, its successors and assigns, as
follows:

            SECTION 1. The Debenture is hereby amended, effective as of the date
first written above, by adding a new subsection "(f)" to such Section 4 of the
Debenture, as follows:

                  "(f) Standstill. Anything contained herein to the contrary
      notwithstanding, during the period from and including July 14, 1997, to
      and including February 13, 1998 (the "Standstill Period"), no record
      Holder of Debentures shall be entitled to convert any Debentures held by
      such Holder, except to the extent that the aggregate principal amount of
      Debentures converted by such Holder (or redeemed by the Company in lieu of
      conversion) during the Standstill Period does not, during the period
      indicated below, exceed the applicable aggregate percentage set forth
      below of the
<PAGE>   19
      principal amount of Debentures held by such Holder on the first day of the
      Standstill Period:

<TABLE>

            <S>                                          <C>
            From and including July 14, 1997,

            From and including October 14, 1997,
                  to and including November 13, 1997...      40%

            From and including November 14, 1997,
                  to and including December 13, 1997...      55%

            From and including December 14, 1997,
                  to and including January 13, 1998....      70%

            From and including January 14, 1998,
                  to and including February 13, 1998...      85%

            From and after February 14, 1998...........     100%
</TABLE>

      For all purposes of this Section 4(f) any Holder (a "Transferee") that
      acquires Debentures during the Standstill Period from another Holder (the
      "Transferor") in any single transaction (the "Transfer") shall be deemed
      (i) to have held at the beginning of the Standstill Period Debentures in
      the aggregate principal amount equal to the product of (x) the aggregate
      principal amount of Debentures held by the Transferor at the beginning of
      the Standstill Period times (y) the Acquired Percentage; and (ii) to have
      converted (or have had redeemed by the Company in lieu of conversion)
      during the period from the beginning of the Standstill Period through the
      date of such Transfer Debentures in the aggregate principal amount equal
      to the product of (x) the aggregate principal amount of Debentures
      converted by such Transferor (or redeemed by the Company in lieu of
      conversion) from the beginning of the Standstill Period through the date
      of such Transfer times (y) the Acquired Percentage. As used in this
      paragraph, the term "Acquired Percentage" means the percentage that the
      aggregate principal amount of Debentures acquired by the Transferee from
      the Transferor in such Transfer bears to the aggregate principal amount of
      Debentures held by the Transferor immediately before giving effect to such
      Transfer. Upon any Transfer, for all purposes of this Section 4(f), the
      Transferor shall be deemed (i) to have held at the beginning of the
      Standstill Period Debentures in the aggregate principal amount equal to
      the product of (x) the aggregate principal amount of Debentures held by
      the Transferor at the beginning of the Standstill Period times (y) the
      difference between 100% and the Acquired Percentage; and (ii) to have
      converted (or have had


                                  Page 2 of 4
<PAGE>   20
      redeemed by the Company in lieu of conversion) during the period from the
      beginning of the Standstill Period through the date of such Transfer
      Debentures in the aggregate principal amount equal to the product of (x)
      the aggregate principal amount of Debentures converted by such Transferor
      (or redeemed by the Company in lieu of conversion) from the beginning of
      the Standstill Period through the date of such Transfer times (y) the
      difference between 100% and the Acquired Percentage. In the event of
      successive Transfers, this paragraph will be applied successively.

      Notwithstanding anything herein to the contrary, if at any time during the
      Standstill Period the Company shall, in breach of its obligations
      hereunder, fail to convert (or to redeem in lieu of conversion) any
      Debentures (or portion thereof) held of record by the Holder of this
      Debenture and properly presented for conversion by the Holder pursuant to
      this Section 4 (and which the Holder is entitled to convert pursuant to
      this Section 4(f)), then, upon written notice by the Holder to the Company
      given pursuant to this paragraph (and without limiting any other rights or
      remedies of the Holder in respect of such failure to convert), so long as
      such default by the Company shall continue, the provisions of this Section
      4(f) shall not apply to the Holder.

            SECTION 2. The Debenture is hereby amended, effective as of the date
first written above, by deleting the figure "$2.00" in clause (x) of Section
4(a), immediately prior to the words "(the 'Fixed Conversion Price')" and
inserting the figure "$1.00" in lieu thereof.

            SECTION 3. Except as otherwise expressly provided herein, the
Debenture shall remain in full force and effect as originally issued, and all
the terms and provisions thereof, except as expressly modified herein, are
hereby ratified and affirmed.

            SECTION 4. The Holder represents and warrants that it is the
beneficial and record owner of the Debenture on the date first written above and
covenants and agrees to firmly affix this Allonge to the Debenture, whereupon it
shall become a part thereof.

                             Note Purchase Agreement

Dear Sirs:

                  This letter sets forth the terms and conditions on which
Lasertechnics, Inc., a Delaware corporation (the "Company"), is issuing and
selling to each of WPLP and JPMIC (each, a "Purchaser") on the date hereof: (a)
a Senior Promissory Note of the Company in substantially the form attached
hereto as Exhibit A (each, a "Note"); (b) the number of shares (the "Restricted
Shares") of Common Stock, $.01 par value (the "Common Stock"), of the Company
determined as set forth in paragraph 2, below; and (c) a warrant in
substantially the form attached hereto as Exhibit B (each, a "Warrant") to
purchase the number of shares (the "Warrant Shares") of Common Stock determined
as set forth in paragraph 3, below.

                  1.       Senior Promissory Notes.

                           (a)      General.  The Senior Promissory Notes shall 
represent and evidence the indebtedness of the Company to the Purchasers for
advances made by the Purchasers to the Company from time to time thereunder
("Advances"), including without limitation the unpaid principal amount of, and
accrued interest on, all Advances, and any additional amounts that may be owed
by the Company to the Purchasers in respect thereof. Advances shall be made from
time to time in cash, or by the cancellation and exchange of other existing
indebtedness, as the Company may request; provided, however, that (i) the
Purchasers shall not be obligated to make any Advances in excess of the initial
Advances made by each Purchaser on the date hereof, (ii) the Purchasers shall
not be entitled to make any Advances, or to purchase any Notes or Warrants
hereunder, unless requested by the Company, and (iii) except as

Lasertechnics, Inc.
Note Purchase Agreement, dated June 25, 1997
Page 2 of 11

provided in paragraph 1(c), below, any Advances made by the Purchasers hereunder
shall be made 60% by WPLP and 40% by JPMIC, unless both WPLP and JPMIC agree to
a different ratio. The rights and obligations of WPLP and JPMIC hereunder are
several and independent, and nothing herein shall be construed to constitute
either WPLP or JPMIC as the agent, representative, partner, joint venturer or
fiduciary of the other.

                           (b)      Interest Rate.  The Base Interest Rate for 
all Advances by WPLP under its Note shall be 10.00% per annum. The Base Interest
Rate for all Advances by JPMIC under its Note shall be 6.64% per annum.

                           (c)      Prior Advance by WPLP.  Concurrently with 
the purchase and sale of the Notes hereunder (the "Initial Closing"), the
Company and WPLP have agreed to convert certain prior advances by WPLP to the
Company in the aggregate principal amount of $1,000,000 (the "Prior Advances")
into Advances under the Notes. Accordingly, at the Initial Closing: (i) the
Prior Advances shall be recorded with appropriate notations on the Notes; (ii)
all promissory notes representing the Prior Advances, and all common stock
warrants issued by the Company to WPLP in respect of the Prior Advances, shall
be canceled and surrendered to the Company against receipt of the securities
issued to WPLP hereunder; and (iii) the indebtedness of the Company to WPLP
represented by the Prior Advances shall constitute an Advance by WPLP to the
Company under the Notes in the aggregate principal amount of the Prior Advances,
for all purposes hereof.

                  2.       Restricted Shares.  Upon the making of each Advance 
under the Notes, the Company shall issue to each Purchaser 45.714 Restricted
Shares for each $1,000 principal amount of such Advance.

                  3.       Common Stock Warrants. Upon the making of each
Advance under the Notes, the Company shall issue to each Purchaser a Warrant
representing the right to purchase 200 Warrant Shares for each $1,000 principal
amount of such Advance, at an exercise price of $.70 per share. Each Warrant
shall be exercisable for a period of three years from the date of issuance.

                  4.       Allocation of Purchase Price. The amount of each
Advance hereunder shall be allocated as purchase price among the Notes (or, in
the case of any Advance following the Initial Closing, the increase in the
principal amount of the Notes), the Restricted Shares and the Warrants being
purchased by each Purchaser hereunder in such manner as such Purchaser shall
reasonably determine with the Company's consent, which consent shall not
unreasonably be withheld or delayed;

Lasertechnics, Inc.
Note Purchase Agreement, dated June 25, 1997
Page 3 of 11

provided, however, that the portion of such purchase price allocated to such
Restricted Shares shall not in any event be less than the par value per share of
the Common Stock at the time of such Advance multiplied by the number of such
shares.

                  5.       Loan Fee. In consideration for work performed in
connection with structuring, arranging for and providing the financings
contemplated hereby, upon the making of each Advance under the Notes, the
Company shall pay to each Purchaser a loan fee (the "Loan Fee") in the amount of
4% of the principal amount of such Advance, payable in shares of Common Stock,
valued at $.70 per share (the "Loan Fee Shares").

                  6.       Pledge of Subsidiary Stock.

                            (a) The obligations of the Company under the Notes,
                  including without limitation the principal amount of, and
                  accrued interest on, all Advances, shall be ratably secured by
                  the pledge and collateral assignment of, and the grant of a
                  security interest in, all the issued and outstanding shares
                  (the "Pledged Shares") of capital stock of Lasertechnics
                  Marking Corporation, a wholly-owned subsidiary of the Company
                  (the "Stock Pledge"). The Stock Pledge shall be on such terms
                  as are reasonable and customary for transactions such as the
                  transactions contemplated hereby. Prior to the occurrence of
                  an event of default under the Notes, the Purchasers shall not
                  have any rights with respect to the voting or disposition of
                  any shares of such subsidiary capital stock so pledged.

                            (b) Concurrently, with the execution and delivery of
                  this Agreement, the Company is delivering to JPMIC, as
                  collateral agent for the benefit of the holders of the Notes,
                  ratably in proportion to the respective aggregate unpaid
                  principal amounts thereof (the "Collateral Agent"),
                  certificates representing the Pledged Shares, together with
                  stock powers in customary form. The Company hereby pledges the
                  Pledged Shares to the Collateral Agent, and grants to the
                  Collateral Agent a security interest therein, to secure the
                  full and timely payment and performance of all obligations of
                  the Company under the Notes, in accordance with paragraph
                  6(a), above, effective at the Initial Closing. The parties
                  shall use their respective best commercially reasonable
                  efforts to negotiate, execute and deliver a definitive pledge
                  agreement, in customary and reasonable form, to further
                  document the Stock Pledge on terms and conditions consistent
                  with the terms and conditions set forth

Lasertechnics, Inc.

Page 4 of 11

                  herein (the "Pledge Agreement"), and upon the effectiveness of
                  the Pledge Agreement, the terms of the Pledge Agreement shall
                  amend and supersede any contrary provisions of this paragraph
                  6(b).

                  7. Late Payment. In the event the Company fails to repay the
entire principal amount of, and accrued interest on, all Advances by 3:00 p.m.,
New York City time, on the Final Maturity Date, the Company shall issue to each
Purchaser the following additional consideration as a late payment fee:

                            (a) that number of shares of Common Stock equal to
                  (i) the aggregate unpaid principal amount of all Advances
                  outstanding on the Final Maturity Date, times (ii) 1%, divided
                  by (iii) the average closing price per share of the Common
                  Stock for the 10 trading days immediately preceding the Final
                  Maturity Date, as reported in the Wall Street Journal (or, if
                  not so reported, as determined in good faith by a majority of
                  the disinterested members of the Board of Directors of the
                  Company) (such average, the "Current Market Price"); and

                            (b) a Warrant to purchase that number of shares of
                  Common Stock equal to (i) the aggregate unpaid principal
                  amount of all Advances outstanding on the Final Maturity Date,
                  times (ii) 5%, divided by (iii) the Current Market Price on
                  the Final Maturity Date; such warrant to be exercisable for a
                  period of three years commencing on the Final Maturity Date,
                  at an exercise price per share equal to the Current Market
                  Price on the Final Maturity Date.

                  The provision of this paragraph 7 will be subject to
appropriate adjustments in the event of any stock split, reverse stock split, or
similar transaction affecting the Common Stock between the date hereof and the
Final Maturity Date.

                  8. Securities Act Legend. The securities issued pursuant to
this Agreement, including the Notes, the Restricted Shares, the Warrants, the
Loan Fee Shares, and any additional shares of Common Stock and Warrants issued
pursuant to paragraph 7 hereof, will not be registered under the Securities Act
of 1933, as amended (the "Securities Act"). Certificates representing the
Restricted Shares, shares of Common Stock issued upon exercise of Warrants, and
shares of Common Stock issued in payment of the Loan Fee or pursuant to
paragraph 7(a) shall bear a restrictive legend substantially to the effect of
the following:

Page 5 of 11

                  "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                  UNDER THE SECURITIES ACT OF 1933, OR APPLICABLE STATE
                  SECURITIES LAWS, NOR THE SECURITIES LAWS OF ANY OTHER
                  JURISDICTION. THEY MAY NOT BE SOLD OR TRANSFERRED IN THE
                  ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THOSE
                  SECURITIES LAWS OR PURSUANT TO AN EXEMPTION THEREFROM."

                  9. Right to Exchange Notes. Each Purchaser shall have the
non-assignable right, exercisable upon 30 days' prior written notice to the
Company given at any time after September 1, 1997, to exchange the unpaid
principal amount of the Advances of such Purchaser, in whole or in part, for an
equal principal amount of convertible debentures of the Company having
substantially the same economic terms and conditions as the Company's existing
10% convertible debentures due March 1, 1999 (or any other convertible debt
security issued to refinance, or in substitution or exchange for, such
convertible debentures), as such terms and conditions shall be in effect at the
time of any exchange pursuant to this paragraph 9.

                  10. Representations and Warranties by the Company. The Company
hereby represents and warrants to each Purchaser as follows:

                            (a) The Company is a corporation duly organized,
                  validly existing and in good standing under the laws of the
                  State of Delaware, and has the corporate power and authority
                  to execute, deliver and perform its obligations under this
                  Agreement, the Notes, the Warrants and the Pledge Agreement.

                           (b) The execution and delivery by the Company of this
                  Agreement, the Notes, the Warrants and the Pledge Agreement,
                  and the performance by the Company of its obligations
                  hereunder and thereunder, have been duly authorized by all
                  requisite corporate action on the part of the Company and will
                  not (i) violate any provision of law, statute, rule or
                  regulation or any order of any court or other agency of
                  government, (ii) conflict with or violate the Certificate of
                  Incorporation or By-Laws of the Company, in each case as
                  amended to the date hereof, or (iii) violate, conflict with or
                  constitute (with due notice or lapse of time or both) a
                  default under any indenture, mortgage, lease, license,
                  agreement or other contract or instrument or result in the
                  creation or imposition of any lien, charge or encumbrance of
                  any nature whatsoever upon the properties or assets of the
                  Company or any of its subsidiaries

                  (other than the lien of the Stock Pledge granted hereunder and
                  under the Pledge Agreement), in each case if such violation,
                  conflict, default, lien, charge or encumbrance would have a
                  material adverse effect on the Company.

                           (c) This Agreement, the Notes and the Warrants have
                  been duly executed and delivered by the Company and
                  constitute, and the Pledge Agreement when duly executed and
                  delivered will constitute, the valid and legally binding
                  obligations of the Company, enforceable in accordance with
                  their respective terms, except to the extent the
                  enforceability thereof may be limited by applicable
                  bankruptcy, moratorium or similar laws affecting the rights of
                  creditors generally.

                           (d) Based in part upon the representations and
                  warranties of each Purchaser contained in this Agreement, no
                  registration or filing with, or consent or approval of, or
                  other action by, any federal, state or other governmental
                  department, commission, board, bureau, agency or
                  instrumentality or any third party is or will be necessary for
                  (a) the Company's execution and delivery of this Agreement,
                  the Notes and the Warrants, and the Company's performance of
                  its obligations hereunder and thereunder.

                            (e) Attached hereto as Schedule 10(e) are (i) a
                  memorandum dated June 19, 1997, from the Company's subsidiary
                  Sandia Imaging Systems Corporation, stating that division's
                  outstanding accounts receivable, firm orders and verbal orders
                  as of June 18, 1997, and (ii) a letter dated June 20, 1997,
                  from the Company's subsidiary Lasertechnics Marking
                  Corporation, stating that division's outstanding accounts
                  receivable and firm orders as of June 18, 1997. Such
                  memorandum and letter, and the attachments thereto, were
                  prepared by the Company in good faith and are believed by the
                  Company to be accurate. The accounts receivable reflected
                  therein represent valid accounts for goods sold and/or
                  services performed in the conduct of the Company's business.

                           (f) The Restricted Shares and the Loan Fee Shares
                  issued to such Purchaser hereunder are, and the Warrant
                  Shares, when issued upon the exercise of such Purchaser's
                  Warrant in accordance with the terms hereof will be, duly
                  authorized, validly issued, fully paid and non-assessable, and
                  are not subject to any pre-emptive rights.

                           (g) The Company is the record holder and beneficial
                  owner of the Pledged Shares and owns the Pledged Shares free
                  and clear of all liens and encumbrances, other than the lien
                  of the Stock Pledge created hereunder and under the Pledge
                  Agreement.

                  11. Representations and Warranties of Each Purchaser. Each
Purchaser hereby severally represents and warrants to the Company as follows:

                           (a) Such Purchaser is acquiring the Note, the Warrant
                  and the Restricted Shares to be purchased by it hereunder, and
                  the Loan Fee Shares issued to it pursuant to paragraph 5
                  hereof (collectively, the "Acquired Securities"), and, if such
                  Purchaser acquires Warrant Shares upon the exercise of such
                  Warrant, such Purchaser will be acquiring such Warrant Shares,
                  for its own account, for investment and not with a view to the
                  distribution thereof within the meaning of the Securities Act.

                           (b) Such Purchaser understands that the Acquired
                  Securities have not been, and the Warrant Shares will not be,
                  registered under the Act, by reason of their issuance by the
                  Company in transactions exempt from the registration
                  requirements of the Act, and that such Acquired Securities and
                  Warrant Shares must be held by such Purchaser indefinitely
                  unless a subsequent disposition thereof is registered under
                  the Act or is exempt from such registration.

                            (c) Such Purchaser further understands that the
                  exemption from registration afforded by Rule 144 (the
                  provisions of which are known to it) promulgated under the Act
                  depends on the satisfaction of various conditions, and that,
                  if applicable, Rule 144 may afford the basis for sales only in
                  limited amounts.

                           (d) Such Purchaser understands that its investments
                  hereunder involve substantial risks and represents and
                  warrants that it has made such independent examination and
                  investigation of the Company as it has deemed necessary in
                  making its investment decision.

                           (e) Such Purchaser is able to bear the economic risk
                  of the investments contemplated by this Agreement and has such
                  knowledge and experience in financial and business matters
                  that it is capable of evaluating the merits and risks of the
                  investment contemplated by this Agreement.

                  12. Miscellaneous. (a) This Agreement, the Notes and the
Warrants constitute our entire agreement with respect to the subject matter
hereof, and this Agreement may not be modified or amended or any provision
hereof waived except by an instrument in writing signed by the Company and each
Purchaser.

                           (b) This Agreement, the Notes and the Warrants shall
                  be binding upon and inure to the benefit of the parties hereto
                  and their respective successors and permitted assigns. The
                  rights of each Purchaser hereunder shall be assignable to any
                  holder of the Notes, provided that the right of each Purchaser
                  under paragraph 9 above to exchange Notes for Convertible
                  Debentures shall not be assignable to any person without the
                  prior written consent of the Company. Except as provided in
                  the immediately preceding sentence, this Agreement and the
                  rights of the Purchasers hereunder shall not be assignable and
                  any purported assignment thereof shall be void.

                           (c) This Agreement may be executed in any number of
                  counterparts and on separate counterparts, each of which shall
                  be an original instrument, but all of which together shall

                                PLEDGE AGREEMENT.


         PLEDGE AGREEMENT dated as of the 18th day of August, 1997 (the
"Agreement") by and among Lasertechnics, Inc., a Delaware corporation (the
pledgor"), Wolfensohn Partners L.P., a Delaware limited partnership (the
"Partnership"), J.P. Morgan Investment Corporation, a Delaware corporation
("JPMIC"), and JPMIC as agent for the Partnership and JPMIC.

         WHEREAS, in order to induce the Partnership and JPMIC to, among other
things, make the loans contemplated by that certain Note Purchase Agreement,
dated as of June 25, 1997 (the "Note Purchase Agreement"), by and among the
Pledgor, the Partnership and JPMIC, Pledgor has agreed to grant a pledge and
security interest to Agent (as such term is hereinafter defined) for the ratable
benefit of the Partnership and JPMIC (collectively, the "Lenders") in the shares
of Lasertechnics Marking Corporation, a Delaware corporation and wholly-owned
subsidiary of Pledgor ("Marking"), now owned and hereafter acquired by Pledgor
(the "Shares") on the terms and conditions contained herein;

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements hereinafter contained, the parties hereto agree as follows:

         1. Creation of Security Interest. (a) As collateral security for the
payment in full of all of the Secured Obligations (as such term is hereinafter
defined), the Pledgor hereby pledges, hypothecates, assigns, transfers, sets
over and delivers unto the Agent, and hereby grants to the Agent for the ratable
benefit of the Partnership and JPMIC a first lien and security interest in, all
of the Shares, the proceeds thereof, and all cash, securities or other property
at any time and from time to time receivable or otherwise distributed in respect
of or in exchange for any of the Shares (all the Shares, proceeds thereof, cash,
securities and other property being hereinafter collectively referred to as the
"Collateral"). Concurrently with the execution of this Agreement, the Pledgor is
delivering to the Agent (i) the stock certificates listed on Schedule A hereto
(the "Delivered Stock"), and (ii) duly endorsed irrevocable stock powers in
blank for the Delivered Stock.

            (b) This Agreement secures, and the Collateral is collateral
security for, the prompt payment and performance in full when due, whether at
stated maturity, by required prepayment, declaration, acceleration, demand or
otherwise (including the payment of amounts that would become due but for the
operation of the
<PAGE>   2
automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C.
Section 362(a)), of all obligations and liabilities of every nature of Pledgor
now or hereafter existing under or arising out of or in connection with the Note
Purchase Agreement and the Senior Promissory Notes issued thereunder (the
"Senior Promissory Notes"), and all extensions or renewals thereof, whether for
principal, interest (including interest that, but for the filing of a petition
in bankruptcy with respect to Pledgor, would accrue on such obligations), fees,
expenses, indemnities or otherwise, whether voluntary or involuntary, direct or
indirect, absolute or contingent, liquidated or unliquidated, whether or not
jointly owed with others, and whether or not from time to time decreased or
extinguished and later increased, created or incurred, and all or any portion of
such obligations or liabilities that are paid, to the extent all or any part of
such payment is avoided or recovered directly or indirectly from Agent or either
Lender as a preference, fraudulent transfer or otherwise, and all obligations of
every nature of Pledgor now or hereafter existing under this Agreement (all such
obligations of Pledgor being the "Secured Obligations").

         2.    Stock Dividends and Adjustments; Voting Rights.

               (a) In the event that during the term of this Agreement any stock
dividend, reclassification, stock split, readjustment, warrant, option or right
to acquire additional securities is issued with respect to the Collateral or any
part thereof, or any other changes are made in the capital structure of Marking,
the Pledgor shall deliver promptly to the Agent all the new, substituted or
additional shares or securities (collectively, the "Additional Securities") it
has received together with appropriate instruments of transfer duly endorsed in
blank. From and after the time the Pledgor has received any Additional
Securities they shall be deemed to be part of the Collateral pledged hereunder.

               (b) So long as a Default, as defined below, shall not have
occurred and be continuing, the Pledgor shall be the sole owner of the
securities that are part of the Collateral and shall have and be entitled to
exercise all rights which a holder of such securities would be entitled to
exercise, including the right (i) to vote all securities that are part of the
Collateral and (ii) to dispose of the securities that are part of the Collateral
in a transaction which results in the discharge of Pledgor's obligations under
the Senior Promissory Notes. Upon the occurrence and during the continuance of a
Default, the Agent shall have exclusive voting rights for such securities.

         3.    Representations, Warranties  and  Covenants.  The Pledgor hereby
represents, warrants and covenants that:


                                       2
<PAGE>   3
                  (i)      the Pledgor is the sole legal and beneficial owner of
the Collateral, free and clear of any adverse claims, and the Pledgor has the
unrestricted right to transfer, pledge and deliver the Collateral to the Company
hereunder;

                  (ii)     the Delivered Stock constitutes all of the issued and
outstanding capital stock of Marking as of the date hereof (in this regard
Pledgor represents and the other parties hereto acknowledge that options to
purchase 482,500 shares of the Common Stock, par value $.01 per share ("Common
Stock"), have been issued to directors and employees of Marking pursuant to the
1995 Stock Option Plan of Marking (the "Plan") and 17,500 additional shares of
Common Stock may be issued pursuant to the Plan);

                  (iii)    the Pledgor will preserve and defend all right, title
and interest of the Agent in and to the Collateral against all claims made by
third parties thereon; and

                  (iv)     the pledge of the Delivered Stock made hereby and the
delivery of the Delivered Stock in accordance herewith are effective to vest in
the Agent a valid and perfected first priority security interest in the
Delivered Stock as set forth herein.

         4.    Default, Remedies.  (a)  A "Default" shall occur hereunder if:

                  (i)      the Pledgor shall fail to pay the principal of, or
interest on, any Senior Promissory Note on the date when due, whether at
maturity, by acceleration or otherwise; or

                  (ii)     an Insolvency Event (as such term is hereinafter
defined) occurs with respect to the Pledgor or Marking; or

                  (iii)    this Agreement shall for any reason whatsoever cease
to be a valid, binding and enforceable agreement against Pledgor; or

                  (iv)     the Pledgor sells, assigns, transfers or otherwise
disposes of, or grants a lien on or security interest in or option or right with
respect to, or otherwise encumbers the Collateral or any part thereof or any
interest therein, provided that either of the following shall not be deemed to
be a Default: (A) any issuance of Common Stock upon the exercise of options
granted pursuant to the Plan or


                                       3
<PAGE>   4
(B) a disposition of securities that are part of the Collateral contemplated by
Section 2(b); or

                  (v)      any of the Collateral shall be attached or levied
upon or seized in any legal proceedings, or held by virtue of any levy or
distraint, which attachment, levy or distraint shall not be vacated within 60
days; or

                  (vi)     the Pledgor otherwise defaults in the observance or
performance of any material representation or other material covenant or
agreement contained herein, the Senior Promissory Notes or in the Note Purchase
Agreement, and such default continues for a period of 20 days after notice
thereof.

              (b) Upon the occurrence and during the continuance of a Default
hereunder, the Agent shall have the right, at the request of the Required
Lenders (as such term is hereinafter defined), in addition to any other rights
granted under the Note Purchase Agreement or the Senior Promissory Notes, to
pursue all of the rights and remedies with respect to the Collateral of a
secured party under the Uniform Commercial Code as adopted and amended in the
State of New York as in effect from time to time or any other applicable law,
all of which rights and remedies, to the full extent permitted by law, shall be
cumulative and not alternative. In addition, from and after the occurrence of a
Default, each Lender may independently exercise any rights or remedies in
respect of the Senior Promissory Notes not provided for herein, and the Agent
acknowledges the authority of the Lenders to exercise such rights and remedies.

              (c) The Pledgor agrees that ten business days shall constitute
reasonable notice of a sale or other disposition of the Collateral. The proceeds
from any such sale or other disposition, after deducting therefrom all expenses
incurred in connection therewith (including reasonable legal fees and expenses)
and after payment in full of the Secured Obligations, shall be paid over to the
Pledgor. The Agent agrees that a private sale of the Collateral shall be held on
commercially reasonable terms; provided, however, that the Agent is authorized
in its absolute discretion to restrict the prospective purchasers to such
persons who represent and agree to the satisfaction of the Agent and its counsel
that such person is purchasing the Collateral for his own account, for
investment, and not with a view to or for sale in connection with a distribution
in violation of the Securities Act of 1933 or any other applicable law or
regulation.

              (d) As used in this Agreement, an "Insolvency Event" with respect
to any Person (as such term is hereinafter defined) shall mean, the making by
such Person of a general assignment made by such Person for the benefit of
creditors;


                                       4
<PAGE>   5
or an order, judgment or decree is entered adjudicating such Person bankrupt or
insolvent; or any order for relief with respect to such Person is entered under
the Bankruptcy Code; or such Person petitions or applies to any tribunal for the
appointment of a custodian, trustee, receiver or liquidator of such Person or of
any substantial part of the assets of such Person, or commences any proceeding
relating to such Person under any bankruptcy, reorganization, arrangement,
insolvency, readjustment of debt, dissolution or liquidation law of any
jurisdiction; or any such petition or application is filed, or any such
proceeding is commenced, against such Person and either (A) such Person by any
act indicates its approval thereof, consent thereto or acquiescence therein or
(B) such petition, application or proceeding is not dismissed within 30 days.

            (e) As used in this Agreement, the term "Person" shall mean and
include an individual, a partnership, a limited liability company, a joint
venture, a corporation, a trust, an unincorporated organization and a
governmental entity or any department or agency thereof.

         5. Waiver of Rights or Remedies. (a) The Agent, by act, delay,
omission, acceptance of partial payment or otherwise, shall not be deemed to
have waived any rights or remedies hereunder, unless such waiver is in writing
and signed by the Agent, and then only to the extent therein set forth. A waiver
by the Agent of any right or remedy on any one occasion, shall not be construed
as a bar to or waiver of any such right or remedy, or both, which the Agent
otherwise would have had on any future occasion.

            (b) To the full extent that the Pledgor may lawfully so agree, the
Pledgor shall not at any time plead, claim or take the benefit of any moratorium
or redemption law now or hereafter enforced, in order to prevent or delay the
enforcement of this Agreement or the application of any portion or all of the
Collateral as provided by this Agreement, and the Pledgor, for itself and all
who may claim under the Pledgor, to the extent legally permitted, hereby waive
the benefit of all such laws. Nothing herein constitutes a waiver of the
Pledgor's rights arising under the provisions of the Uniform Commercial Code as
in effect in the State of New York from time to time.

         6. Further Assurances. The Pledgor agrees that it shall at the request
of the Agent execute and deliver all such further assignments, endorsements and
other documents and take all such further action as the Agent may reasonably
request in order to effect the purposes and provisions of this Agreement and to
perfect, continue,


                                       5
<PAGE>   6
better assure or confirm the rights of the Agent in the Collateral provided for
hereunder.

         7. Termination. The security interest and assignment created and
granted hereunder shall terminate only when the Pledgor has fully satisfied all
of the obligations under the Senior Promissory Notes and no Default, or event
which with notice or lapse of time or both would constitute a Default, has
occurred and is continuing, and upon such termination all Collateral in the
possession of the Agent shall be returned to the Pledgor, accompanied by
appropriate stock powers, without recourse to the Agent.

         8. Notices. Notices or other communications to any of the parties
hereto shall be in writing and shall be given, in the case of the Pledgor and
the Lenders, as provided in the Note Purchase Agreement and, in the case of the
Agent, to J.P. Morgan Investment Corporation, 60 Wall Street, New York, New York
10260, attention: Mr. Robert Kiss and Mr. James P. Marriott. Pledgor agrees that
any notices or other communications sent by it to either Lender shall also be
sent to the Agent.

         9. Appointment of Agent.

            (a) By the execution and delivery of this Agreement, each of the
Lenders appoints, and by its execution hereof the Pledgor hereby acknowledges,
JPMIC, as collateral agent for itself and the Partnership under this Agreement
and for the purposes herein stated and any and all incidental and related
rights, powers, remedies, actions, steps and matters (in such capacity herein
referred to as the "Agent," which term shall include successors and assigns), to
take any and every action allowed pursuant to this Agreement, and to protect all
rights of each Lender as herein provided or as otherwise agreed, from time to
time, by those Lenders holding at least 90% of the aggregate total of the
Secured Obligations owed to all Lenders (the "Required Lenders"); provided,
however, if a Default shall have occurred, either Lender, acting individually,
may instruct the Agent to the same extent as the Required Lenders, but without
approval of, or consent by, the Pledgor or any other Person, including with
respect to all rights as provided in the Uniform Commercial Code of the State of
New York as now in effect or hereafter amended or any other applicable law, as
now in effect or hereafter amended to increase said rights of the Agent or the
Lenders; provided, however, that with respect to any determination to be made at
such time as only one Lender shall hold any Secured Obligations, the Agent shall
act solely at the request of such Lender. It is acknowledged and agreed that the
relationship of the Agent and Lenders shall be that of principals and agent and
not, in any event, that of partners or joint venturers. Neither this Agreement
nor any document executed in


                                        6
<PAGE>   7
connection herewith shall be deemed to create or establish a partnership or
joint venture among any of the parties hereto or thereto. Agent shall not have,
by reason of this Agreement or otherwise, a fiduciary relationship in respect of
any Lender.

            (b) The security interests granted to the respective Lenders shall
each be of equal priority and any and all amounts realized as a result of any
disposition or collection of Collateral shall be shared on a pro rata basis
based upon the ratio of the amount of Secured Obligations owed to each
respective Lender to the aggregate total of the Secured Obligations owed to all
Lenders, such ratio to be calculated on the basis of the Secured Obligations
outstanding on the date of determination (such ratio is hereinafter referred to
as such Lender's "Pro Rata Share").

            (c) Neither the Agent nor any of its officers, directors, employees
or agents shall be liable to Lenders for any action taken or omitted by Agent
under or in connection with this Agreement except to the extent caused by
Agent's gross negligence or willful misconduct. The Agent shall be entitled to
refrain from any act or the taking of any action (including the failure to take
an action) in connection with this Agreement or from the exercise of any power,
discretion or authority vested in it hereunder unless and until Agent shall have
received instructions in respect thereof from the Required Lenders and, upon
receipt of such instructions from the Required Lenders, Agent shall be entitled
to act or (where so instructed) refrain from acting, or to exercise such power,
discretion or authority, in accordance with such instructions. Without prejudice
to the generality of the foregoing, (i) Agent shall be entitled to rely, and
shall be fully protected in relying, upon any communication, instrument or
document believed by it to be genuine and correct and to have been signed or
sent by the proper person or persons, and shall be entitled to rely and shall be
protected in relying on opinions and judgments of attorneys (who may be
attorneys for Pledgor and its subsidiaries or for any Lender), accountants,
experts and other professional advisors selected by it; and (ii) no Lender shall
have any right of action whatsoever against Agent as a result of Agent acting or
(where so instructed) refraining from acting under this Agreement or any of the
other Loan Documents in accordance with the instructions of Required Lenders.

            (d) Each Lender, in proportion to its Pro Rata Share, severally
agrees to indemnify Agent, to the extent that Agent shall not have been
reimbursed by Pledgor, for and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses
(including counsel fees and disbursements) or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by or asserted against Agent
in exercising its powers, rights and remedies or performing its duties hereunder
or otherwise in its capacity as Agent in any way relating to or


                                       7
<PAGE>   8
arising out of this Agreement; provided that no Lender shall be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from Agent's gross
negligence or willful misconduct. If any indemnity furnished to Agent for any
purposes shall, in the opinion of Agent, be insufficient or become impaired,
Agent may call for additional indemnity and cease, or not commence, to do the
acts indemnified against until such additional indemnity is furnished.

            (e) Agent may resign at any time by giving 30 days' prior written
notice thereof to Lenders and Pledgor, and Agent may be removed at any time with
or without cause by an instrument or concurrent instruments in writing delivered
to Pledgor and Agent and signed by the Required Lenders. Upon any such notice of
resignation or any such removal, the Required Lenders shall have the right, upon
five business days' notice to Pledgor, to appoint a successor Agent. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, that
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring or removed Agent and the
retiring or removed Agent shall be discharged from its duties and obligations
under this Agreement. After any retiring or removed Agent's resignation or
removal hereunder as Agent, the provisions of this Section 9 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement. Notwithstanding anything in this Agreement to the
contrary, JPMIC may resign as Agent hereunder at any time and substitute the

                              AMENDED AND RESTATED
                          GRID NOTE WITH LIBOR PRICING

                                                              New York, New York
$7,000,000                                                 As of August 19, 1997

         WHEREAS, on December 5, 1996, a Grid Note with Libor Pricing in the
principal amount of $7,000,000 (the "Original Note") was entered into between
Republic National Bank of New York ("Bank") and Wolfensohn Associates, L.P.
("WALP I").

         WHEREAS, on August 18, 1997 and August 19, 1997, WALP I and Wolfensohn
Associates II L.P. ("WALP II") entered into an Assignment and Assumption
Agreement (collectively, the "Agreements") providing for the transfer by WALP I
of all of its assets to WALP II and the assumptions by WALP II of the
obligations and liabilities of WALP I, including without limitation under the
Original Note and the Continuing General Security Agreement dated December 5,
1996 between WALP I and the Bank.

         NOW THEREFORE, to reflect changes to the terms and conditions of the
Original Note agreed to between WALP II and the Bank, the undersigned and the
Bank agree to amend and restate the Original Note in its entirety as follows:

         FOR VALUE RECEIVED, the undersigned ("Maker") promises to pay to the
order of REPUBLIC NATIONAL BANK OF NEW YORK ("Bank") at its principal banking
office at 452 Fifth Avenue, New York, New York 10018 or at any of its other
banking offices in New York as Bank may designate by written notice to Maker,
the sum of SEVEN MILLION DOLLARS, or so much thereof as shall be advanced by
Bank to Maker, in Bank's sole discretion, in one or more loans (each an
"Advance" and collectively the "Advances") and not repaid, on August 31, 1998
(the "Maturity Date"), or with respect to each Advance on the Due Date (as
defined below) of such Advance, whichever first occurs, and to pay interest on
each Advance from the date of such Advance until the date on which such Advance
is paid in full, at the rate and in the manner provided below.

         Each Advance shall be due on a date (the "Due Date") one or more months
from the date of such Advance (the "Term") and have an Interest Period (as
defined below) as specified in writing by the Maker in the Maker's request (the
"Request") for such Advance. In no event shall any Term for any Advance end
later than the Maturity Date. Provided that no Event of Default (as defined
below) has occurred and is continuing, Maker may make a written request upon
Bank (the "Extension Request") to extend the maturity date of an Advance beyond
its original Term or the then current additional Term, as the case may be, for
an additional Term, to commence on the expiration of the original Term or the
then current additional Term, as the case may be, and end on or prior to the
Maturity Date, and have an Interest Period, as specified


                                       1
<PAGE>   2
by Maker in the Extension Request. Bank must receive the Extension Request at
least seven Business Days prior to the expiration of the original Term or the
then current additional Term, as the case may be, of said Advance and shall
decide in its sole discretion, for no reason or for any reason whatsoever,
whether to agree to the requested extension. If Maker does not receive written
notice from Bank at least three Business Days prior to the expiration of the
original Term for such Advance that Bank has agreed to the Extension Request,
then such Advance will continue to be due and payable on the last day of the
original Term or the then current additional Term, as the case may be. In any
event, interest on such Advance shall continue to be due and payable as set
forth herein regardless of whether Bank agrees to the Extension Request.

         Prior to the occurrence of any Event of Default, each Advance shall
bear interest during its Term at a rate (the "Contract Rate") equal to 2% per
annum above LIBOR (as defined below) for each Interest Period applicable to such
Advance, each adjustment to take effect on the first day of each Interest Period
applicable to such Advance.

         Interest on each Advance will be due and payable on the last day of
each month and on the last day of each Interest Period and on payment in full of
such Advance. After the occurrence of an Event of Default, interest under this
Note on each Advance shall be payable on demand and shall accrue on each Advance
at a rate per annum equal to 2% per annum above the Contract Rate otherwise
chargeable on such Advance hereunder. Interest shall be calculated on the basis
of a 360-day year for actual days elapsed. In no event shall the interest rate
applicable at any time to this Note exceed the maximum rate permitted by law.

         For purposes hereof, the term "Interest Period" shall mean for each
Advance, each consecutive one, two, three or six month period, as specified by
Maker in the Request for such Advance. The first Interest Period in respect of
an Advance shall commence on the date of such Advance and each successive
Interest Period in respect of such Advance shall commence immediately at the end
of the preceding Interest Period. Maker must specify an Interest Period for each
Advance such that the Term for each Advance must be equal to or an integral
multiple of the specified Interest Period for such Advance.

         As used herein, "LIBOR" means with respect to an Advance the rate per
annum, rounded upward to the nearest 1/8th of 1%, quoted at approximately 11:00
A.M. London time, two Business Days (as defined below) prior to the first day of
each successive Interest Period by Bank's principal branch in London, England,
for offering to leading banks in the London Interbank Market for United States
Dollar deposits in an amount comparable to the principal amount of such Advance
for a period equal to the Interest Period applicable to such Advance.

         If Bank determines, in its sole discretion, during the term of this
Note, that (A) by reason of circumstances affecting the London Interbank Market
generally, adequate and fair means do not exist for ascertaining an applicable
LIBOR or it is impractical for Bank to continue to fund any Advance during an
applicable Interest Period, or (B) quotes for funds in United States Dollars


                                       2
<PAGE>   3
in sufficient amounts comparable to any Advance and for the duration of the
applicable Interest Period for such Advance would not be available to Bank in
the London Interbank Market, or (C) quotes for funds in United States Dollars in
the London Interbank Market will not accurately reflect the cost to Bank of
funding any Advance during an applicable Interest Period, or (D) the making or
funding of loans, or charging of interest at rates, based on LIBOR shall be
unlawful or unenforceable for any reason, then as long as such circumstance(s)
shall continue, any such Advance shall bear interest at a variable rate equal to
the Reference Rate (as defined below) and such rate shall be the Contract Rate
for all other purposes hereof. As used herein, "Reference Rate" means the rate
established by Bank from time to time at its principal domestic office as its
reference rate for domestic commercial loans. Bank may make loans to customers
above, at or below the Reference Rate. Any change in the Reference Rate shall
become effective on the date of such change.

         This Note evidences Advances made by Bank to Maker from time to time.
The Bank agrees to make Advances to Maker prior to the Maturity Date and
provided that (a) no Event of Default (as hereinafter defined) has occurred and
(b) no Margin Shortfall (as defined in the Amended Margin Agreement dated as of
August 19, 1997 and executed and delivered by the Maker to the Bank as a rider
to the Continuing General Security Agreement dated December 5, 1996 from
Wolfensohn Associates L.P. in favor of the Bank and any amendments, restatements
or modifications thereto) has occurred and is continuing at the time an Advance
hereunder is requested by the Maker.

         The unpaid principal balance of this Note at any time shall be the
total of all Advances made by Bank to Maker in Bank's sole discretion, less the
total amount of principal payments made hereon by Maker. The date, the amount of
each such Advance, the Due Date and applicable Contract Rate as adjusted as set
forth above for each such Advance, any extensions of an Advance as agreed to by
Bank as set forth herein and in its sole discretion, and each payment on account
of principal thereof shall be recorded by Bank on its books and records, and
when so recorded shall represent evidence thereof binding upon Maker in the
absence of manifest error.

         Each payment to be made hereunder shall be free and clear of, and
without deductions for or on account of any present or future taxes, imposts,
charges, levies, compulsory loans or other withholdings or deductions
whatsoever. If the Maker shall be required by applicable law to make any such
deduction from any payment hereunder, (i) the sum payable shall be increased as
may be necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this paragraph) the Bank
receives an amount equal to the sum it would have received had no deductions
been made, (ii) the Maker shall make such deductions, and (iii) the Maker shall
pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law. In addition, the Maker agrees to
pay, if necessary, all stamp, documentary, or similar taxes or any other excise
or property taxes, charges or similar levies which arise from any payment made
hereunder or from the execution, delivery or registration of, or otherwise with
respect to, this instrument.


                                       3
<PAGE>   4
         To induce Bank, in its sole discretion, to make Advances to Maker,
Maker represents, warrants and covenants to Bank that (i) Maker is a limited
partnership which is duly formed and validly existing in good standing under the
laws of the jurisdiction of its formation, with full power and authority to
make, deliver and perform this Note; (ii) the execution, delivery and
performance by Maker of this Note have been duly authorized, by all necessary
action, and does not and will not violate or conflict with, its partnership
agreement, or in any case, any law, rule, regulation or order binding on Maker
or any agreement or instrument to which Maker is a party or which may be binding
on Maker; (iii) this Note has been fully executed by the general partner of
Maker and, in any case, constitutes a legal, valid, binding and enforceable
obligation of Maker; (iv) no authorization, consent, approval, license,
exemption of or filing or registration with, any court or government or
governmental agency is or will be necessary to the valid execution, delivery or
performance by Maker of this Note; (v) the Advances evidenced by this Note will
be used for general business purposes and investments; and (vi) there are no
pending or threatened actions, suits or proceedings against or affecting maker
by or before any court, commission, bureau or other governmental agency or
instrumentality, which, individually or in the aggregate, if determined
adversely to Maker, would have a material adverse effect on the business,
properties, operations, or condition, financial or otherwise, or Maker.

         Requests for Advances to Maker from Bank and directions as to the
deposition of the proceeds thereof must be given in writing to Bank by the
general partner of Maker or other persons authorized to borrow on Maker's behalf
by borrowing authority and certification of Maker's general partner heretofore
delivered to Bank, as such authority may be amended or superseded from time to
time, provided that any such amending or superseding authority shall have been
certified by an authorized signatory of Maker's general partner, and a copy
thereof, so certified by the authorized signatory of Maker's general partner
shall have been delivered to an officer of Bank at its office for payment. Bank
may conclusively rely on the authorities contained in said resolutions. Any such
Advance so made shall be conclusively presumed to have been made to or for the
benefit of Maker and Maker shall be liable in respect thereof when made in
accordance with any such request or direction, or when deposited to any account
of Maker with Bank, even though persons other than those authorized to borrow on
behalf of Maker may have authority to draw against such account. Bank may rely
on any such request or direction which it believes to be genuine, and Bank shall
be fully protected in so doing without any duty to make further inquiry as to
such genuineness or in otherwise acting in good faith in the premises. By making
a request for an Advance, Maker shall be deemed to be representing to Bank that
all of the representations and warranties of Maker set forth in this Note are
true and correct as of the date of such request as if made on and as of such
date and shall also be deemed to be representing and warranting to Bank that on
such date Maker is not in breach of any of its covenants to Bank set forth in
this Note or in any other document or instruments of Maker to Bank and no event
of default has occurred and is continuing with respect to any Obligations (as
defined below).

         This Note shall be payable in lawful money of the United States of
America ("United States Dollars") in immediately available funds. All payments
on this Note shall be


                                       4
<PAGE>   5
applied to the payment of accrued interest before being applied to the payment
of principal. Any payment which is required to be made on a day which is not a
Business Day (as defined below) shall be payable on the next succeeding Business
Day and such additional time shall be included in the computation of interest.
In the event that any other Obligations of Maker to Bank are due at any time
that Bank receives a payment from Maker on account of this Note or any such
other Obligations of Maker, Bank may apply such payment to amounts due under
this Note or any such other Obligations in such manner as Bank, in its sole
discretion, elects, regardless of any instructions from Maker to the contrary.
As used herein, "Business Day" shall mean a day on which (A) banks are regularly
open for business in both London and New York City and (B) Bank's principal
banking office at 452 Fifth Avenue, New York, New York shall be open for
ordinary business.

         Maker shall be entitled to prepay any Advances in whole but not in part
without penalty or the prior consent of Bank before 11:00 A.M. New York City
time on the last day of any Interest Period (or the next succeeding Business Day
if the last day of such Interest Period is not a Business Day, referred to
herein as a "Prepayment Date") for such Advance together with the payment of all
interest accrued and unpaid on such Advance to the date of such prepayment
provided that Bank has received written notice from Maker, at least seven
Business Days prior to such Prepayment Date, informing Bank that such prepayment
will be made on such Prepayment Date. Maker also shall be entitled to prepay any
Advance in whole but not in part before 11:00 A.M. New York City time on any
Business Day which is not the last day of an Interest Period without the prior
consent of, or any prior notice to, Bank provided that any such prepayment shall
be made together with (i) the payment of all interest accrued and unpaid on the
prepaid Advance to the date of prepayment and (ii) the payment of the Liquidated
Cost (as defined below). As used herein, "Liquidated Cost" means, with respect
to any prepayment, an amount necessary to compensate Bank for the cost of
reinvesting, for the period commencing on the date of the prepayment and
extending to the last day of the then current Interest Period of such prepaid
Advance, the prepaid principal amount received by Bank at a rate or rates which
may be less than the Contract Rate for such prepaid Advance. Maker and Bank
acknowledge that determining the actual amount of the Liquidated Cost may be
difficult or impossible in any specific instance and accordingly Maker agrees
with Bank that the Liquidated Cost shall equal the excess, if any, of (i) the
product of (A) the amount of principal prepaid, multiplied by (B) the Contract
Rate applicable to such Advance which is being prepaid, divided by 360,
multiplied by (C) the remaining number of days from the date of the prepayment
to the end of the then current Interest Period of the Advance which is being
prepaid, over (ii) that amount of interest which Bank determines that the holder
of a Treasury Obligation (as defined below) selected by Bank in the amount (or
as close to such amount as is feasible) of such prepaid Advance and having a
maturity date on the last day of the stated term of such prepaid Advance (or as
soon thereafter as is feasible), would earn if that Treasury Obligation were
purchased in the secondary market on the date of the prepayment and were held to
the last day of the then current Interest Period of such prepaid Advance. Maker
agrees that the determination of Liquidated Cost shall be based on amounts which
a holder of a Treasury Obligation could receive under these circumstances,
whether or not Bank actually invests


                                       5
<PAGE>   6
the prepaid principal amount in any Treasury Obligation. As used herein,
"Treasury Obligation" means a note, bill or bond issued by the United States
Treasury Department as a full faith and credit general obligation of the United
States. Maker agrees that the payment of Liquidated Cost as a premium in
connection with any prepayment is reasonable to compensate Bank for lost income
resulting from such prepayment because Maker is receiving the benefit of having
the Contract Rate priced based on LIBOR.

         If any law, regulation, directive or treaty or any change therein or in
the interpretation or application thereof shall make it unlawful for Bank to
maintain the Advances evidenced by this Note or to claim or receive any amount
otherwise payable under this Note, Bank shall so notify Maker. In the case of
any such notice, Maker shall prepay the outstanding principal amount of this
Note in full together with all accrued interest on such earlier date prior to
the respective Due Dates as Bank may specify and on which Bank may lawfully
receive such payment, if payment on such earlier date is reasonably required as
a result of such impending illegality.

         If, after the date of this Note, the adoption of any applicable law,
ordinance, regulation or rule (a "Governmental Rule"), any change in any
applicable Governmental Rule, any change in the interpretation or administration
of any applicable Governmental Rule by any person charged with the
interpretation or administration thereof, or compliance by Bank with any request
or directive (whether or not having the force of law) of any such person

         (a)      shall subject Bank to any tax, duty or other charge with
                  respect to all or any portion of the Advances or shall change
                  the basis of taxation of payments to Bank of any amounts due
                  under this Note (except for changes in the rate of tax on the
                  overall net income of Bank or any of its offices imposed by
                  the tax laws of any jurisdiction in the world); or

         (b)      shall impose, modify or deem applicable any reserve
                  (including, without limitation, any imposed by the Board of
                  Governors of the Federal Reserve System), special deposit,
                  capital adequacy requirement, capital equivalency, ratio of
                  assets to liabilities or any other capital substitute or
                  similar requirement against assets of, deposits with or for
                  the account of, credit extended by, letters of credit issued
                  and maintained by, or collateral subject to a lien in favor of
                  the Bank, or shall impose on Bank any other condition
                  affecting all or any portion of the Advances,

and the result of any of the foregoing is to increase the cost to or to impose a
cost on Bank of making or maintaining all or any portion of the Advances, or to
reduce the amount of any sum received or receivable by Bank under this Note, or
(in the case of a capital adequacy or similar requirement) to reduce the rate of
return on Bank's capital as a consequence of maintaining all or any portion of
the Advances to a level below that which could have been achieved but for the


                                       6
<PAGE>   7
imposition of such requirement (taking into consideration Bank's capital
adequacy policies), then, within 30 days after demand by Bank, Maker shall pay
Bank for its own account such additional amount or amounts as will compensate
Bank for such increased cost or reduction. Bank will promptly notify Maker of
any event of which it has knowledge, occurring after the date of this Note,
which will entitle Bank to compensation pursuant to this paragraph. A
certificate of Bank claiming compensation for itself under this paragraph and
setting forth in reasonable detail the additional amount or amounts to be paid
to Bank shall be conclusive evidence of the amount of such compensation absent
manifest error. In determining such amount, Bank may use any reasonable
averaging and attribution methods.

         Upon the occurrence of any of the following (each, an "Event of
Default") with respect to any Maker, general partner of Maker, indorser of the
indebtedness evidenced by this Note or James D. Wolfensohn: (i) default in
payment of any amount due (whether at stated maturity, by acceleration, by
notice from Maker as to a prepayment or otherwise) under this Note or in the
payment or performance of any other Obligation or agreement of any nature or
description to or with Bank; (ii) any of them shall commence any case,
proceeding or other action under any law relating to bankruptcy, insolvency,
reorganization or relief of debtors, seeking to have an order for relief entered
with respect to any of them, or seeking to adjudicate any of them a bankrupt or
insolvent, or seeking reorganization, arrangement, adjustment, winding-up,
liquidation, dissolution, composition or other relief with respect to any of
them or any of their debts, or seeking appointment of a receiver, trustee,
custodian or other similar official for any of them or for all or any
substantial part of the assets of any of them, or any of them shall make a
general assignment for the benefit of its creditors, or there shall be commenced
against any of them any case, proceeding or other action of a nature referred to
in this clause (ii), or there shall be commenced against any of them any case,
proceeding or other action seeking issuance of a warrant of attachment,
execution, distraint or similar process against all or any substantial part of
the assets of any of them which results in the entry of an order for any such
relief, or any of them shall take any action in furtherance of, or indicating
its consent to, approval of, or acquiescence in, any of the acts set forth in
this clause (ii), or any of them shall generally not, or shall be unable to, or
shall admit in writing its inability to, pay its debts as they become due; (iii)
entry of a judgment against any of them not paid within 30 days or appealed in
good faith; (iv) failure to pay or remit any tax when assessed or due in excess
of $100,000 (other than taxes contested in good faith); (v) death or
dissolution; (vi) making a bulk transfer or sending notice of intent to do so;
(vii) granting any security interest (other than to Bank); (viii) suspension or
liquidation of the usual business; (ix) failing to furnish Bank with any
requested financial information or failing to permit inspection of books or
records by Bank or any of its agents, attorneys or accountants; (x) making any
misrepresentation to Bank material to the Bank's credit decision; (xi)
impairment of financial responsibility of any of them in Bank's good faith
opinion; (xii) Bank shall in good faith deem itself insecure at any time; (xiii)
the Bank receives notice of the termination of any guarantee of James D.
Wolfensohn relating to the indebtedness evidenced by this Note; or (xiv) the
occurrence of a default or event of default under any security agreement
securing any Obligations of Maker; then, in the case of any Event of Default
other than those referred to in


                                       7
<PAGE>   8
clause (ii) of this sentence, Bank may declare by notice to Maker any and all
Obligations of Maker (including, without limitation, all Liquidated Costs
relating to such Obligations) to be immediately due and payable, and in case of
any Event of Default referred to in clause (ii) of this sentence all of the
Obligations of Maker (including, without limitation, all Liquidated Costs
relating to such Obligations) shall automatically become due and payable
immediately without notice or demand.

         Bank shall have a continuing lien and/or right of set-off on, and is
hereby granted a security interest in, all deposits (general and special) and
credits with Bank or any Bank Affiliate of any Maker and indorser, and may apply
all or part of the same to any Obligations (whether contingent or unmatured) of
Maker, at any time or times, without notice. Bank shall have a continuing lien
on, and is hereby granted a security interest in, all property of every Maker
and indorser and the proceeds thereof held or received by or for Bank or any
Bank Affiliate for any purpose, whether or not for the express purpose of
serving as collateral security for the Obligations of Maker. As used in this
Note, the term "Bank Affiliate" includes any individual, partnership or
corporation acting as nominee or agent for Bank, and any corporation or bank
which is directly or indirectly owned or controlled by, or under common control
with, Bank. Any notice of disposition of property shall be deemed reasonable if
mailed at least five days before such disposition to the last address of Maker
or indorser on Bank's records. If the Obligations of Maker to Bank evidenced by
this Note are secured by a security agreement and/or other security documents
which Maker has separately delivered to Bank (whether or not such documents make
specific reference to this Note), reference to such documents is made for a
description of the collateral provided thereby and of the rights of Maker and
Bank therein. The rights and remedies of Bank provided for hereunder (including
but not limited to the right to accelerate Obligations of Maker and to realize
on any security for any such Obligations) are cumulative with the rights and
remedies of Bank available under any other instrument or agreement or under
applicable law. As used in this Note, the term "Obligations" of a person means
all amounts payable under this Note and any and all other indebtedness,
obligations and liabilities of that person to Bank, and all claims of Bank
against such person, now existing or hereafter arising, direct or indirect
(including participations or any interest of Bank in indebtedness of such person

         In the case of the occurrence of an Event of Default, each Maker and
indorser shall be jointly and severally liable for all costs of enforcement and
collection of this Note incurred by Bank or any other holder of this Note,

         Maker and each indorser hereby separately waive presentment, demand for
payment, notice of dishonor, protest and notice of protest, and any or all other
notices or demands in connection with the delivery, acceptance, performance,
default, endorsement or guarantee of this Note. The liability of any Maker or
indorser hereunder shall be unconditional and shall not be in any manner
affected by any indulgence whatsoever granted or consented to by the holder
hereof, including but not limited to any extension of time, renewal, waiver or
other modification. Any failure of the holder to exercise any right hereunder
shall not be construed as a waiver of the right to exercise the same or any
other right at any time and from time to time thereafter. Bank or any holder may
accept late payments, or partial payments, even though marked "payment in full"
or containing words of similar import or other conditions, without waiving any
of its rights. No amendment, modification or waiver of any provision of this
Note nor consent to any departure by Maker therefrom shall be effective,
irrespective of any course of dealing, unless the same shall be in writing and
signed by Bank, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given. This Note cannot
be changed or terminated orally or by estoppel or waiver or by any alleged oral
modification regardless of any claimed partial performance referable thereto.

         Any notice from Bank to Maker or any indorser shall be deemed given
when delivered to Maker or such indorser by hand or when deposited in the United
States mail and addressed to Maker or such indorser at the last address of Maker
or such indorser appearing on Bank's records.

         This Note shall be governed by and construed in accordance with the
laws of the State of New York applicable to instruments made and to be performed
wholly within that state. If any provision of this Note is held to be illegal or
unenforceable for any reason whatsoever, such illegality or unenforceability
shall not affect the validity of any other provision hereof.

         MAKER AND EACH INDORSER AGREE THAT ANY ACTION, DISPUTE, PROCEEDING,
CLAIM OR CONTROVERSY BETWEEN MAKER OR SUCH INDORSER AND BANK, WHETHER SOUNDING
IN CONTRACT, TORT OR OTHERWISE ("DISPUTE" OR "DISPUTES") SHALL, AT BANK'S
ELECTION, WHICH ELECTION MAY BE MADE AT ANY TIME PRIOR TO THE COMMENCEMENT OF A
JUDICIAL PROCEEDING BY BANK, OR IN THE EVENT OF A JUDICIAL PROCEEDING INSTITUTED
BY MAKER OR SUCH INDORSER AT ANY TIME PRIOR TO THE LAST DAY TO ANSWER AND/OR
RESPOND TO A SUMMONS AND/OR COMPLAINT MADE BY MAKER OR SUCH INDORSER, BE
RESOLVED BY ARBITRATION IN ACCORDANCE WITH THE PROVISIONS OF THIS PARAGRAPH AND
SHALL, AT THE ELECTION OF BANK, INCLUDE ALL DISPUTES ARISING OUT OF OR IN
CONNECTION WITH (1) THIS NOTE OR ANY RELATED AGREEMENTS OR INSTRUMENTS, (2) ALL
PAST, PRESENT AND FUTURE AGREEMENTS INVOLVING MAKER OR SUCH INDORSER AND BANK,
(3) ANY TRANSACTION RELATED TO THIS NOTE AND ALL PAST, PRESENT AND FUTURE

TRANSACTIONS INVOLVING MAKER OR SUCH INDORSER AND BANK, AND (4) ANY ASPECT OF
THE PAST, PRESENT OR FUTURE RELATIONSHIP OF MAKER OR SUCH INDORSER AND BANK.
Bank may elect to require arbitration of any Dispute with Maker or any indorser
without thereby being required to arbitrate all Disputes between Bank and Maker
or such indorser. Any such Dispute shall be resolved by binding arbitration in
accordance with Article 75 of the New York Civil Practice Law and Rules and the
Commercial Arbitration Rules of the American Arbitration Association ("AAA"). In
the event of any inconsistency between such Rules and these arbitration
provisions, these provisions shall supersede such Rules. All statutes of
limitations which would otherwise be applicable shall apply to any arbitration
proceeding under this paragraph. In any arbitration proceeding subject to this
paragraph, the arbitration panel (the "arbitrator") is specifically empowered to
decide (by documents only, or with a hearing, at the arbitrator's sole
discretion) pre-hearing motions which are substantially similar to pre-hearing
motions to dismiss and motions for summary adjudication. In any such arbitration
proceeding, the arbitrator shall not have the power or authority to award
punitive damages to any party. Judgment upon the award rendered may be entered
in any court having jurisdiction. Whenever an arbitration is required, the
parties shall select an arbitrator in the manner provided in this paragraph. No
provision of, nor the exercise of any rights under, this paragraph shall limit
the right of Bank (1) to foreclose against any real or personal property
collateral through judicial foreclosure, by the exercise of the power of sale
under a deed of trust, mortgage or other security agreement or instrument,
pursuant to applicable provisions of the Uniform Commercial Code, or otherwise
herein pursuant to applicable law, (2) to exercise self-help remedies including
but not limited to setoff and repossession, or (3) to request and obtain from a
court having jurisdiction before, during or after the pendency of any
arbitration, provisional or ancillary remedies and relief including but not
limited to injunctive or mandatory relief or the appointment of a receiver. The
institution and maintenance of an action or judicial proceeding for, or pursuit
of, provisional or ancillary remedies or exercise of self-help remedies shall
not constitute a waiver of the right of Bank, even if Bank is the plaintiff, to
submit the Dispute to arbitration if Bank would otherwise have such right.
Whenever an arbitration is required under this paragraph, the arbitrator shall
be selected, except as otherwise herein provided, in accordance with the
Commercial Arbitration Rules of the AAA. A single arbitrator shall decide any
claim of $100,000 or less and he or she shall be an attorney with at least five
years' experience. Where the claim of any party exceeds $100,000, the Dispute
shall be decided by a majority of three arbitrators, at least two of whom shall
be attorneys (at least one of whom shall have not less than five years'
experience representing commercial banks). The arbitrator shall have the power
to award recovery of all costs and fees (including attorneys' fees,
administrative fees, arbitrator's fees, and court costs) to the prevailing
party. In the event of any Dispute governed by this paragraph, each of the
parties shall, subject to the award of the arbitrator, pay an equal share of the
arbitrator's fees.

         MAKER AND EACH INDORSER AGREE THAT ANY ACTION, SUIT OR PROCEEDING IN
RESPECT OF OR ARISING OUT OF THIS NOTE MAY BE INITIATED AND PROSECUTED IN THE
STATE OR FEDERAL COURTS, AS THE


                                       10
<PAGE>   11
CASE MAY BE, LOCATED IN NEW YORK COUNTY, NEW YORK AND ANY ARBITRATION PROCEEDING
PURSUANT HERETO SHALL BE CONDUCTED IN NEW YORK, NEW YORK. MAKER AND EACH
INDORSER CONSENT TO AND SUBMIT TO THE EXERCISE OF JURISDICTION OVER ITS PERSON
BY ANY SUCH COURT HAVING JURISDICTION OVER THE SUBJECT MATTER, WAIVE PERSONAL
SERVICE OF ANY AND ALL PROCESS UPON IT AND CONSENT THAT ALL SUCH SERVICE OF
PROCESS BE MADE BY REGISTERED MAIL DIRECTED TO MAKER OR SUCH INDORSER AT ITS
ADDRESS SET FORTH BELOW OR TO ANY OTHER ADDRESS AS MAY APPEAR IN BANK'S RECORDS
AS THE ADDRESS OF MAKER OR SUCH INDORSER. MAKER AGREES THAT A FINAL JUDGMENT IN
ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER
JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW.

         IN ANY ACTION, SUIT OR PROCEEDING IN RESPECT OF OR ARISING OUT OF THIS
NOTE, MAKER AND EACH INDORSER WAIVE (I) THE RIGHT TO INTERPOSE ANY SET-OFF OR
COUNTERCLAIM OF ANY NATURE OR DESCRIPTION, (II) ANY OBJECTION BASED ON FORUM NON
CONVENIENS OR VENUE AND (III) ANY CLAIM FOR CONSEQUENTIAL, PUNITIVE OR SPECIAL
DAMAGES.

         TO THE EXTENT THAT MAKER OR ANY INDORSER HAS OR HEREAFTER ACQUIRES ANY
IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER FROM
SERVICE OF NOTICE, ATTACHMENT IN AID OF EXECUTION, ATTACHMENT PRIOR TO JUDGMENT,
EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, MAKER AND EACH
INDORSER IRREVOCABLY WAIVE SUCH IMMUNITY IN RESPECT OF THEIR OBLIGATIONS UNDER
THIS NOTE.

         IN ANY ACTION, SUIT OR PROCEEDING IN RESPECT OF OR ARISING OUT OF THIS
NOTE, BANK, MAKER AND EACH INDORSER WAIVE TRIAL BY JURY.

                               LASERTECHNICS, INC.

         WHEREAS, on August 1, 1997, Lasertechnics, Inc. (the "Company") filed
with the Secretary of State of the State of Delaware a Certificate of
Designation of Series F Preferred Stock of the Company (the "Certificate of
Designation");

         WHEREAS, no shares of the Company's Series F Preferred Stock are issued
and outstanding; and

         WHEREAS, the last sentence of Section 5(f) of the Certificate of
Designation inaccurately reflects the corporate action taken with respect to the
subject matter thereof and should be deleted, and in its place four sentences
should be inserted at the end of such Section 5(f).

         NOW, THEREFORE, the Certificate of Designation is hereby corrected in
accordance with the provisions of Section 103(f) of the Delaware General
Corporation Law as follows:

            The last sentence of Section 5(f) of the Certificate of Designation
which currently reads as follows:

         "For purposes of this Section 5(f), any Holder (a "Transferee") that
         acquires shares of Series F Preferred Stock during the Standstill
         Period directly or indirectly from another Holder (the "Transferor")
         that held such shares at the beginning of the Standstill Period, shall
         only be entitled to convert such shares to the extent that the
         aggregate number of such shares converted by such Transferee (or
         redeemed by the Company in lieu of conversion) during the remainder of
         the Standstill Period does not at any time exceed the product of (x)
         the applicable percentage set forth above times (y) the percentage of
         the Transferor's shares of Series F Preferred Stock held at the
         beginning of the Standstill Period that had not been converted (or
         redeemed by the Company in lieu of Conversion) at the time of the
         transfer to the Transferee."

shall be deleted from the Certificate of Designation and the following four last
sentences to Section 5(f) shall be substituted in its place:
<PAGE>   2
      "For all purposes of this Section 5(f) any Holder (a "Transferee") that
      acquires shares of Series F Preferred Stock during the Standstill Period
      from another Holder (the "Transferor") in any single transaction (the
      "Transfer") shall be deemed (i) to have held at the beginning of the
      Standstill Period a number of shares of Series F Preferred Stock equal to
      the product of (x) the number of shares of Series F Preferred Stock held
      by the Transferor at the beginning of the Standstill Period times (y) the
      Acquired Percentage; and (ii) to have converted (or have had redeemed by
      the Company in lieu of conversion) during the period from the beginning of
      the Standstill Period through the date of such Transfer a number of shares
      of Series F Preferred Stock equal to the product of (x) the number of
      shares of Series F Preferred Stock converted by such Transferor (or
      redeemed by the Company in lieu of conversion) from the beginning of the
      Standstill Period through the date of such Transfer times (y) the Acquired
      Percentage. As used in this paragraph, the term "Acquired Percentage"
      means the percentage that the total number of shares of Series F Preferred
      Stock acquired by the Transferee from the Transferor in such Transfer
      bears to the total number of shares of Series F Preferred Stock held by
      the Transferor immediately before giving effect to such Transfer. Upon any
      Transfer, for all purposes of this Section 5(f), the Transferor shall be
      deemed (i) to have held at the beginning of the Standstill Period a number
      of shares of Series F Preferred Stock equal to the product of (x) the
      number of shares of Series F Preferred Stock held by the Transferor at the
      beginning of the Standstill Period times (y) the difference between 100%
      and the Acquired Percentage; and (ii) to have converted (or have had
      redeemed by the Company in lieu of conversion) during the period from the
      beginning of the Standstill Period through the date of such Transfer a
      number of shares of Series F Preferred Stock equal to the product of (x)
      the number of shares of Series F Preferred Stock converted by such
      Transferor (or redeemed by the Company in lieu of conversion) from the
      beginning of the Standstill Period through the date of such Transfer times
      (y) the difference between 100% and the Acquired Percentage. In the event
      of successive Transfers, this paragraph will be applied successively.

            Notwithstanding anything herein to the contrary, if at any time
      during the Standstill Period the Company shall, in breach of its
      obligations hereunder, fail to convert (or to redeem in lieu of
      conversion) any shares of Series F Preferred Stock held of record by the
      Holder thereof and properly presented for conversion by the Holder
      pursuant to this Section 5 (and which the Holder is entitled to convert
      pursuant to this Section 5(f)), then, upon written notice by the Holder to
      the Company given pursuant to this paragraph (and without limiting any
      other rights or remedies of the Holder in respect of such failure to
      convert), so long as such default by the Company shall continue, the
      provisions of this Section 5(f) shall not apply to the Holder."

                          CERTIFICATE OF DESIGNATION OF
                            SERIES F PREFERRED STOCK

                                       OF

                               LASERTECHNICS, INC.


It is hereby certified that:

         1. The name of the Company (hereinafter called the "Company") is
Lasertechnics, Inc., a Delaware corporation.

         2. The certificate of incorporation of the Company authorizes the
issuance of Seven Million (7,000,000) shares of preferred stock, $.01 value per
share, and expressly vests in the Board of Directors of the Company the
authority provided therein to issue any or all of said shares in one or more
series and by resolution or resolutions to establish the designation and number
and to fix the relative rights and preferences of each series to be issued.

         3. The Board of Directors of the Company, pursuant to the authority
expressly vested in it as aforesaid, has adopted the following resolutions
creating a Series F issue of Preferred Stock:

         RESOLVED, that NINE HUNDRED (900) of the Seven Million (7,000,000)
authorized shares of Preferred Stock of the Company shall be designated Series F
Preferred Stock, $.01 par value per share, and shall possess the rights and
preferences set forth below:

        Section 1. Designation and Amount. The shares of such series shall have
a par value of $.01 per share and shall be designated as Series F Preferred
Stock (the "Series F Preferred Stock") and the number of shares constituting the
Series F Preferred Stock shall be NINE HUNDRED (900). The Series F Preferred
Stock shall have a stated value of Ten Thousand Dollars ($10,000) per share (the
"Original Series F Issue Price"), with an eight percent (8%) per annum accretion
rate as set forth herein. The Series F Preferred Stock shall be issued by the
Company only (i) in exchange for an equal number of outstanding shares of Series
D Preferred Stock or Series E Preferred Stock or (ii) for cash, in a transaction
the proceeds of which are used by the Company to fund the redemption or
repurchase of shares of Series D Preferred Stock or Series E Preferred Stock.

         Section 2. Rank. The Series F Preferred Stock shall rank: (i) junior to
any other class or series of capital stock of the Company hereafter created
specifically ranking by its terms senior to the Series F Preferred Stock
(collectively, the "Senior Securities"); (ii) prior to all of the

                                      1

<PAGE>   5
Company's Common Stock, $.01 par value per share ("Common Stock"); (iii) prior
to any class or series of capital stock of the Company hereafter created not
specifically ranking by its terms senior to or on parity with any Series F
Preferred Stock of whatever subdivision (collectively, with the Common Stock,
"Junior Securities"); and (iv) on parity with the Series A Preferred Stock of
the Company, par value $.01 per share (the "Series A Preferred Stock"), the
Series B Preferred Stock of the Company, par value $.01 per share (the "Series B
Preferred Stock"), the Series C Preferred Stock of the Company, par value $.01
per share (the "Series C Preferred Stock"), the Series D Preferred Stock of the
Company, par value $.01 per share (the "Series D Preferred Stock"), the Series E
Preferred Stock of the Company, par value $.01 per share (the "Series E
Preferred Stock") and any class or series of capital stock of the Company
hereafter created specifically ranking by its terms on parity with the Series F
Preferred Stock ("Parity Securities") in each case as to distributions of assets
upon liquidation, dissolution or winding up of the Company, whether voluntary or
involuntary (all such distributions being referred to collectively as
"Distributions").

         Section 3. Dividends. The Series F Preferred Stock will bear no
dividends, and the holders of the Series F Preferred Stock ("Holders") shall not
be entitled to receive dividends on the Series F Preferred Stock.

         Section 4. Liquidation Preference.

            (a) In the event of any liquidation, dissolution or winding up of
the Company ("Liquidation Event"), either voluntary or involuntary, the Holders
of shares of Series F Preferred Stock shall be entitled to receive, immediately
after any distributions to Senior Securities required by the Company's
Certificate of Incorporation or any certificate of designation, and prior in
preference to any distribution to Junior Securities but in parity with any
distribution to Parity Securities, an amount for each share of Series F
Preferred Stock then outstanding equal to the sum of (i) the Original Series F
Issue Price and (ii) an amount equal to eight percent (8%) of the Original
Series F Issue Price per annum for the period that has passed since the date
(the "Initial Funding Date") that, in connection with the consummation of the
original issuance and sale of shares of Series D Preferred Stock by the Company,
the escrow agent first had in its possession funds representing full payment for
the share of Series D Preferred Stock delivered in exchange for such share of
Series F Preferred Stock (such amount being referred to herein as the
"Premium"). If upon the occurrence of such event, and after payment in full of
the preferential amounts with respect to the Senior Securities, the assets and
funds available to be distributed among the Holders of the Series F Preferred
Stock and Parity Securities shall be insufficient to permit the payment to such
Holders of the full preferential amounts due to the Holders of the Series F
Preferred Stock and the Parity Securities, respectively, then the entire assets
and funds of the Company legally available for distribution shall be distributed
among the Holders of the Series F Preferred Stock and the Parity Securities, pro
rata, based on the respective liquidation amounts to which each such series of
stock is entitled by the Company's Certificate of


                                       2
<PAGE>   6
Incorporation and any certificate(s) of designation relating thereto.
Notwithstanding the foregoing, for all purposes hereof, including without
limitation calculating the Premium: in the case of any share of Series F
Preferred Stock issued in exchange for a share of Series E Preferred Stock, the
Initial Funding Date should be May 18, 1997; and in the case of any share of
Series F Preferred Stock issued for cash pursuant to clause (ii) of Section 1
hereof, the Initial Funding Date shall be the date on which such share was
purchased and paid for by the original holder thereof.

            (b) Upon the completion of the distribution required by subsection
4(a), if assets remain in this Company, they shall be distributed to holders of
Junior Securities in accordance with the Company's Certificate of Incorporation
including any duly adopted certificate(s) of designation.

            (c) At each Holder's option, a sale, conveyance or disposition of
all or substantially all of the assets of the Company or the effectuation by the
Company of a transaction or series of related transactions in which any person
or entity acquires more than fifty percent (50%) of the voting power of the
Company (a "Change of Control") shall be deemed to be a Liquidation Event as
defined in Section 4(a); provided further that (i) a consolidation, merger,
acquisition, or other business combination of the Company with or into any other
publicly traded company or companies shall not be treated as a Liquidation Event
as defined in Section 4(a), but instead shall be treated pursuant to Section
5(e)(iii) hereof, and (ii) a consolidation, merger, acquisition, or other
business combination of the Company with or into any other non-publicly traded
company or companies shall be treated as a Liquidation Event as defined in
Section 4(a). The Company shall not effect any transaction described in
subsection 4(c)(ii) unless it first gives thirty (30) business days prior notice
of such transaction (during which time the Holder shall be entitled to convert
its shares of Series F Preferred Stock into Common Stock). For purposes of this
Section 4(c), the public offering, sale or distribution of shares of stock (or
assets) of the Company's Sandia Imaging Systems Corp. subsidiary or the
Lasertechnics Marking Corporation subsidiary (but not both) shall not be deemed
to be a Liquidation Event.

            (d) In the event that, immediately prior to the closing of a
transaction described in Section 4(c) which would constitute a Liquidation
Event, the cash distributions required by Section 4(a) or Section 6 have not
been made, the Company shall either: (i) cause such closing to be postponed
until such cash distributions have been made, or (ii) cancel such transaction,
in which event the rights of the Holders of Series F Preferred Stock shall be
the same as existing immediately prior to such proposed transaction.

         Section 5. Conversion. The record Holders of this Series F Preferred
Stock shall have conversion rights as follows (the "Conversion Rights"):


                                       3
<PAGE>   7
            (a) Right to Convert. Subject to the Company's right of redemption
set forth in Section 6(a) and to the limitations set forth in Section 5(f), and
on the terms and subject to the conditions set forth in this Certificate of
Designation, each record Holder of Series F Preferred Stock shall be entitled to
convert the shares of Series F Preferred Stock held by such Holder, in whole at
any time and in part from time to time, into that number of fully-paid and
non-assessable shares of Common Stock of the Company calculated in accordance
with the following formula (the "Conversion Rate"):

         Number of shares issued upon conversion of one share of Series F
         Preferred Stock =

                         (.08) (N/365) (10,000) + 10,000
                         -------------------------------
                                Conversion Price

         where,

         - N = the number of days between (i) the Initial Funding Date for the
         shares of Series F Preferred Stock for which conversion is being
         elected, and (ii) the applicable Date of Conversion (as defined in
         Section 5(c)(iv) below) for the shares of Series F Preferred Stock for
         which conversion is being elected, and

         - Conversion Price = the lesser of (x) $1.1406 (the "Fixed Conversion
         Price"), or (y) X% of the average Closing Bid Price, as that term is
         defined below, of the Company's Common Stock for the ten (10) trading
         days immediately preceding the Date of Conversion, as defined below
         (the "Variable Conversion Price"), where X is determined as follows:

<TABLE>

                   No. of Days Between Last
            Closing Date and Date of Conversion         X =

<S>                                                    <C>
                        60 - 119                         90%

</TABLE>

      For purposes hereof, the term "Closing Bid Price" shall mean the closing
bid price on the Nasdaq Small Cap Market, or if no longer traded on the Nasdaq
Small Cap Market, the closing bid price on the principal national securities
exchange or the National Market System on which the Common Stock is so traded
and if not available, the mean of the high and low prices on the principal
national securities exchange or the National Market System on which the Common
Stock is so traded. The term "Last Closing Date" means July 29, 1996.

            (b) Mechanics of Conversion. In order to convert Series F Preferred
Stock into full shares of Common Stock, the Holder shall (i) fax, on or prior to
8:00 p.m., New York City


                                       4
<PAGE>   8
time (the "Conversion Notice Deadline") on the date of conversion, a copy of the
fully executed notice of conversion ("Notice of Conversion") to the Company at
the office of the Company or its designated transfer agent (the "Transfer
Agent") for the Series F Preferred Stock stating that the Holder elects to
convert, which notice shall specify the date of conversion, the number of shares
of Series F Preferred Stock to be converted, the applicable conversion price and
a calculation of the number of shares of Common Stock issuable upon such
conversion (together with a copy of the front page of each certificate to be
converted) and (ii) surrender to a common courier for delivery to the office of
the Company or the Transfer Agent the original certificates representing the
Series F Preferred Stock being converted (the "Preferred Stock Certificates"),
duly endorsed for transfer; provided, however, that the Company shall not be
obligated to issue certificates evidencing the shares of Common Stock issuable
upon such conversion unless either the Preferred Stock Certificates are
delivered to the Company or its Transfer Agent as provided above, or the Holder
notifies the Company or its Transfer Agent that such certificates have been
lost, stolen or destroyed (subject to the requirements of subparagraph (i)
below). Upon receipt by Company of a facsimile copy of a Notice of Conversion,
Company shall immediately send, via facsimile, a confirmation of receipt of the
Notice of Conversion to Holder which shall specify that the Notice of Conversion
has been received and the name and telephone number of a contact person at the
Company whom the Holder should contact regarding information related to the
Conversion. In the case of a dispute as to the calculation of the Conversion
Rate, the Company shall promptly issue to the Holder the number of Shares that
are not disputed and shall submit the disputed calculations to its outside
accountant via facsimile within three (3) days of receipt of Holder's Notice of
Conversion. The Company shall cause the accountant to perform the calculations
and notify Company and Holder of the results no later than forty-eight (48)
hours from the time it receives the disputed calculations. Accountant's
calculation shall be deemed conclusive absent manifest error.

            (i)  Lost or Stolen Certificates. Upon receipt by the Company of
evidence of the loss, theft, destruction or mutilation of any Preferred Stock
Certificates representing shares of Series F Preferred Stock, and (in the case
of loss, theft or destruction) of indemnity or security reasonably satisfactory
to the Company, and upon surrender and cancellation of the Preferred Stock
Certificate(s), if mutilated, the Company shall execute and deliver new
Preferred Stock Certificate(s) of like tenor and date. However, Company shall
not be obligated to re-issue such lost or stolen Preferred Stock Certificates if
Holder contemporaneously requests Company to convert such Series F Preferred
Stock into Common Stock.

            (ii) Delivery of Common Stock Upon Conversion. The Transfer Agent or
the Company (as applicable) shall use its best efforts to, no later than the
close of business on the second (2nd) business day and in no event later than
the third (3rd) business day (the "Deadline") after receipt by the Company or
the Transfer Agent of a facsimile copy of a Notice of Conversion and receipt by
Company or the Transfer Agent of all necessary documentation duly executed and
in proper form required for conversion, including the original Preferred Stock


                                       5
<PAGE>   9
Certificates to be converted (or after provision for security or indemnification
in the case of lost or destroyed certificates, if required), issue and surrender
to a common courier for either overnight or (if delivery is outside the United
States) two-day delivery to the Holder at the address of the Holder as shown on
the stock records of the Company a certificate for the number of shares of
Common Stock to which the Holder shall be entitled as aforesaid.

                  (iii)    No Fractional Shares. If any conversion of the Series
F Preferred Stock would create a fractional share of Common Stock or a right to
acquire a fractional share of Common Stock, such fractional share shall be
disregarded and the number of shares of Common Stock issuable upon conversion,
in the aggregate, shall be the next lower number of shares.

                  (iv)     Date of Conversion. The date on which conversion
occurs (the "Date of Conversion") shall be deemed to be the date set forth in
such Notice of Conversion, provided (i) that the advance copy of the Notice of
Conversion is faxed to the Company before 8:00 p.m., New York City time, on the
Date of Conversion, and (ii) that the original Preferred Stock Certificates
representing the shares of Series F Preferred Stock to be converted are
surrendered by depositing such certificates with a common courier, for delivery
to the Company or the Transfer Agent as provided above, as soon as practicable
after the Date of Conversion. The person or persons entitled to receive the
shares of Common Stock issuable upon such conversion shall be treated for all
purposes as the record Holder or Holders of such shares of Common Stock on the
Date of Conversion.

         (c)      Reservation of Stock Issuable Upon Conversion. The Company
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the Series F Preferred Stock, such number of its shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all then outstanding
Series F Preferred Stock; and if at any time the number of authorized but
unissued of Series F Preferred Stock, the Company will take such corporate
action as may be necessary to increase its authorized but unissued shares of
Common Stock to such number of shares as shall be sufficient for such purpose.

         (d)      Automatic Conversion. Each share of Series F Preferred Stock
outstanding on the date which is three (3) years after the Last Closing Date
automatically shall be converted into Common Stock on such date at the
Conversion Rate then in effect (calculated in accordance with the formula in
Section 5(a) above), and the date which is three (3) years after the Last
Closing Date shall be deemed the Date of Conversion with respect to such
conversion.

         (e)      Adjustment to Conversion Rate.

                  (i)      Adjustment to Fixed Conversion Price Due to Stock
Split, Stock Dividend, Etc. If, prior to the conversion of all of the Series F
Preferred Stock, the number of


                                       6
<PAGE>   10
outstanding shares of Common Stock is increased by a stock split, stock
dividend, or other similar event, the Fixed Conversion Price shall be
proportionately reduced, or if the number of outstanding shares of Common Stock
is decreased by a combination or reclassification of shares, or other similar
event, the Fixed Conversion Price shall be proportionately increased.

                  (ii)     Adjustment to Variable Conversion Price. If, at any
time when any shares of the Series F Preferred Stock are issued and outstanding,
the number of outstanding shares of Common Stock is increased or decreased by a
stock split, stock dividend, or other similar event, which event shall have
taken place during the reference period for determination of the Conversion
Price for any conversion of the Series F Preferred Stock, then the Variable
Conversion Price shall be calculated giving appropriate effect to the stock
split, stock dividend, combination, reclassification or other similar event for
all five (5) trading days immediately preceding the Date of Conversion.

                  (iii)    Adjustment Due to Merger, Consolidation, Etc. If,
prior to the conversion of all Series F Preferred Stock, there shall be any
merger, consolidation, exchange of shares, recapitalization, reorganization, or
other similar event, as a result of which shares of Common Stock of the company
shall be changed into the same or a different number of shares of the same or
another class or classes of stock or securities of the Company or another entity
or there is a sale of all or substantially all the Company's assets or there is
a Change of Control not deemed to be a liquidation pursuant to section 4(c),
then the Holders of Series F Preferred Stock shall thereafter have the right to
receive upon conversion of Series F Preferred Stock, upon the basis and upon the
terms and conditions specified herein and in lieu of the shares of Common Stock
immediately theretofore issuable upon conversion, such stock, securities and/or
other assets which the Holder would have been entitled to receive in such
transaction had the Series F Preferred Stock been converted immediately prior to
such transaction, and in any such case appropriate provisions shall be made with
respect to the rights and interests of the Holders of the Series F Preferred
Stock to the end that the provisions hereof (including, without limitation,
provisions for the adjustment of the Conversion Price and of the number of
shares issuable upon conversion of the Series F Preferred Stock) shall
thereafter be applicable, as nearly as may be practicable in relation to any
securities thereafter deliverable upon the exercise hereof. The Company shall
not effect any transaction described in this subsection 5(3)(iii) unless (a) it
first gives thirty (30) business days prior notice of such merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event (during which time the Holder shall be entitled to convert its
shares of Series F Preferred Stock into Common Stock) and (b) the resulting
successor or acquiring entry (if not the Company) assumes by written instrument
the obligations of the Company under this Certificate of Designation including
this subsection 5(e)(iii).

                  (iv)     No Fractional Shares. If any adjustment under this
Section 5(e) would create a fractional share of Common Stock or a right to
acquire a fractional share of


                                       7
<PAGE>   11
Common Stock, such fractional share shall be disregarded and the number of
shares of Common Stock issuable upon conversion shall be the next lower number
of shares.

            (f) Standstill. Anything contained herein to the contrary
notwithstanding, during the period from and including July 14, 1997, to and
including February 13, 1998 (the "Standstill Period"), no record Holder of
Series F Preferred Stock shall be entitled to convert any shares of Series F
Preferred Stock held by such Holder, except to the extent that the aggregate
number of shares of Series F Preferred Stock converted by such Holder (or
redeemed by the Company in lieu of conversion) during the Standstill Period does
not, during the period indicated below, exceed the applicable aggregate
percentage set forth below of the number of shares of Series F Preferred Stock
held by such Holder on the first day of the Standstill Period:

For purposes of this Section 5(f), any Holder (a "Transferee") that acquires
shares of Series F Preferred Stock during the Standstill Period directly or
indirectly from another Holder (the "Transferor") that held such shares at the
beginning of the Standstill Period, shall only be entitled to convert such
shares to the extent that the aggregate number of such shares converted by such
Transferee (or redeemed by the Company in lieu of conversion) during the
remainder of the Standstill Period does not at any time exceed the product of
(x) the applicable percentage set forth above times (y) the percentage of the
Transferor's shares of Series F Preferred Stock held at the beginning of the
Standstill Period that had not been converted (or redeemed by the Company in
lieu of Conversion) at the time of the transfer to the Transferee.

         Section 6. Redemption by Company.

                  (a)      Company's Right to Redeem Upon Receipt of Notice of
Conversion. If the Conversion Price of the Company's Common Stock is less than
the Fixed Conversion Price (as defined in Section 5(a)), at the time of receipt
of a Notice of Conversion pursuant to Section 5, the Company shall have the
right, in its sole discretion, to redeem in whole or in part any Series F
Preferred Stock submitted for conversion, immediately prior to and in lieu of
conversion ("Redemption Upon Receipt of Notice of Conversion"). If the Company
elects to redeem some, but not all, of the Series F Preferred Stock submitted
for conversion, the Company shall redeem from among the Series F Preferred Stock
submitted by the various shareholders for conversion on the applicable date, a
pro-rata amount from each such Holder so submitting Series F Preferred Stock for
conversion.

                           (i)      Redemption Price Upon Receipt of a Notice of
Conversion. The redemption price per share of Series F Preferred Stock under
this Section 6(a) shall be calculated in accordance with the following formula
("Redemption Rate"):

  [[(.08)(N/365)(10,000)] + 10,000] X Closing Bid Price on Date of Conversion
                                      ---------------------------------------
                                                  Conversion Price

where,

         "N", "Date of Conversion", "Closing Bid Price" and "Conversion Price"
shall have the same meanings as defined in Section 5.

                           (ii)     Mechanics of Redemption Upon Receipt of
Notice of Conversion. The Company shall effect each such redemption by giving
notice of its election to redeem, by facsimile, by 5:00 p.m. New York City time
the next business day following receipt of a Notice of Conversion from a Holder,
and the Company shall provide a copy of such redemption notice by overnight or
two-day courier, to (A) the Holder of the Series F Preferred Stock submitted for
conversion at the address and facsimile number of such Holder appearing in the
Company's register for the Series F Preferred Stock and (B) the Company's
Transfer Agent. Such redemption notice shall indicate whether the Company will
redeem all or part of the Series F Preferred Stock submitted for conversion and
the applicable redemption price.

                  (b)      Company's Rights to Redeem at its Election. At any
time, commencing twelve months and one day after the Last Closing Date, the
Company shall have the right, in its sole discretion, to redeem ("Redemption at
Company's Election"), from time to time, any or all of the Series F Preferred
Stock; provided (i) Company shall first provide thirty (30) business days
advance written notice as provided in subparagraph 6(b)(ii) below (which can be
given beginning thirty (30) business days prior to the date which is twelve
months and one day after the Last


                                       9
<PAGE>   13
Closing Date), and (ii) that, in the case of any partial redemption, the Company
shall only be entitled to redeem Series F Preferred Stock having an aggregate
Stated Value (as defined below) of at least One Million Dollars ($1,000,000). If
the Company elects to redeem some, but not all, of the Series F Preferred Stock,
the Company shall redeem a pro rata amount from each Holder of the Series F
Preferred Stock.

            (i)  Redemption Price At Company's Election. The "Redemption Price 
At Company's Election" shall be calculated as a percentage of Stated Value, as
that term is defined below, of the Series F Preferred Stock redeemed pursuant to
this Section 6(b), which percentage shall vary depending on the date of
Redemption at Company's Election (as defined below), and shall be determined as
follows:

Date of Notice of Redemption at Company's Election             % of Stated Value
- --------------------------------------------------             -----------------

12 months and 1 day to 18 months following Last Closing Date         130%
18 months and 1 day to 24 months following Last Closing Date         125%
24 months and 1 day to 30 months following Last Closing Date         120%
30 months and 1 day to 36 months following Last Closing Date         115%

         For purposes hereof, "Stated Value" shall mean the Original Series F
Issue Price (as defined in Section 1) of the shares of Series F Preferred Stock
being redeemed pursuant to this Section 6(b), together with the accreted but
unpaid Premium (as defined in Section 4(a)).

            (ii) Mechanics of Redemption at Company's Election. The Company
shall effect each such redemption by giving at least thirty (30) business days
prior written notice ("Notice of Redemption At Company's Election") to (A) the
Holders of the Series F Preferred Stock selected for redemption, at the address
and facsimile number of such Holder appearing in the Company's Series F
Preferred Stock register and (B) the Transfer Agent, which Notice of Redemption
At Company's Election shall be deemed to have been delivered three (3) business
days after the Company's mailing (by overnight or two-day courier, with a copy
by facsimile) of such Notice of Redemption At Company's Election. Such Notice of
Redemption At Company's Election shall indicate (i) the number of shares of
Series F Preferred Stock that have been selected for redemption, (ii) the date
which such redemption is to become effective (the "Date of Redemption At
Company's Election") and (iii) the applicable Redemption Price At Company's
Election, as defined in subsection (b)(i) above. Notwithstanding the above,
Holder may convert into Common Stock pursuant to Section 5, prior to the close
of business on the Date of Redemption at Company's Election, any Series F
Preferred Stock which it is otherwise entitled to convert, including Series F
Preferred Stock that has been selected for redemption at Company's election
pursuant to this subsection 6(b); provided, however, that the Company shall
still be entitled to exercise its right to redeem upon receipt of a Notice of
Conversion pursuant to section 6(a).


                                       10
<PAGE>   14
         (c)      Company Must Have Immediately Available Funds or Credit
Facilities. The Company shall not be entitled to send any Redemption Notice and
begin the redemption procedure under Sections 6(a) and 6(b) unless it has:

                  (i)   the full amount of the redemption price in cash, 
available in a demand or other immediately available account in a bank or
similar financial institution; or

                  (ii)  immediately available credit facilities, in the full
amount of the redemption price with a bank or similar financial institution; or

                  (iii) an agreement with a standby underwriter willing to
purchase from the Company a sufficient number of shares of stock to provide
proceeds necessary to redeem any stock that is not converted prior to
redemption; or

                  (iv)  a combination of the items set forth in (i), (ii) and
(iii) above, aggregating the full amount of the redemption price.

    If the foregoing conditions of this Section 6(c) are satisfied and
Company complies with Section 6(d) hereof, then any shares of Series F Preferred
Stock called for by a Redemption at Company's Election shall cease to be
outstanding for all purposes hereunder (including the right to convert or to
accrete additional Premium or to exercise any other right or privilege
hereunder) on the Date of Redemption at Company's Election and shall instead
represent the right to receive the Redemption Price at Company's Election
without interest from and after the Date of Redemption at Company's Election.

         (d)      Payment of Redemption Price.

                  (i)   Each Holder submitting Preferred Stock being redeemed
under this Section 6 shall send their Series F Preferred Stock Certificates so
redeemed to the Company or its Transfer Agent, and the Company shall pay the
applicable redemption price to that Holder within five (5) business days of the
Date of Redemption at Company's Election. The Company shall not be obligated to
deliver the redemption price unless the Preferred Stock Certificates so redeemed
are delivered to the Company or its Transfer Agent, or, in the event one (1) or
more certificates have been lost, stolen, mutilated or destroyed, unless the
Holder has complied with Section 5(c)(i).

                  (ii)  If Company elects to redeem pursuant to Section 6(a)
hereof, and Company fails to pay Holder the redemption price within the time
frame as required by this Section 6(d), then Company shall issue shares of
Common Stock to any such Holder who has submitted a Notice of Conversion in
compliance with Section 5(c) hereof. The shares to be issued to Holder pursuant
to this provision shall be the number of shares determined using a Conversion


                                       11
<PAGE>   15
Price (as defined in Section 6 hereof) that equals the lesser of (i) the
Conversion Price on the date Holder sends its Notice of Conversion to Company or
Transfer Agent via facsimile or (ii) the Conversion Price on the date the
Transfer Agent issues Common Stock pursuant to this Section 6(d)(ii).

            (e) Blackout Period. Notwithstanding the foregoing, the Company may
not either send out a redemption notice or effect a redemption pursuant to
Section 6(b) above during a Blackout Period (defined as a period during which
the Company's officers or directors would not be entitled to buy or sell stock
because of their holding of material non-public information), unless the Company
shall first disclose the non-public information that resulted in the Blackout
Period; provided, however, that no redemption shall be effected until at least
ten (10) days after the Company shall have given the Holder written notice that
the Blackout Period has been lifted.

         Section 7. Advance Notice of Redemption.

            (a) Holder's Right to Elect to Receive Notice of Cash Redemption by
the Company. Holder shall have the right to require Company to provide advance
notice stating whether the Company will elect to redeem Holder's shares of
Series F Preferred Stock in cash, pursuant to the Company's redemption rights
discussed in Section 6(a).

            (b) Mechanics of Holder's Election Notice. Holder shall send notice
("Election Notice") to the Company and such other person(s) as the Company may
designate via facsimile, stating Holder's intention to require Company to
disclose that if Holder were to exercise his, her or its right of conversion
(pursuant to Section 5) whether Company would elect to redeem a specific number
of shares of Holder's Series F Preferred Stock for cash in lieu of issuing
Common Stock. Company is required to disclose to Holder what action Company
would take over the subsequent twenty (20) business day period, including the
date of such Election Notice, as further discussed in subsection 7(c).

            (c) Company's Response. Upon receipt by the Company of a facsimile
copy of an Election Notice, Company shall immediately send, via facsimile, a
confirmation of receipt of the Election Notice to Holder, which shall specify
that the Election Notice has been received and the name and telephone number of
a contact person at the Company whom the Holder should contact regarding
information related to the requested advance notice. Thereafter, the Company
must respond by the close of business on the next business day following receipt
of Holder's Election Notice (1) via facsimile and (2) by depositing such
response with an overnight or two-day courier. The Company's response must state
whether it would redeem the shares, in whole or in part, or allow conversion
into shares of Common Stock without redemption. If Company does not respond to
Holder within one (1) business day via facsimile and overnight or two-day
courier, Company shall be required to issue to Holder Common Stock upon Holder's
conversion within the subsequent twenty (20) business day period of Holder's
Election Notice. However, if the


                                       12
<PAGE>   16
Company's Common Stock price decreases so that under the Conversion Rate Company
would be required to issue more than an additional ten percent (10%) of shares
of Common Stock than Holder was entitled to receive at the time Holder sent
Company its Election Notice, then Company shall no longer be bound to convert
Holder's Preferred Stock into Common Stock but may elect to redeem for cash.

         Section 8. Voting Rights. The Holders of the Series F Preferred Stock
shall have no voting power whatsoever, except as otherwise provided by the
corporation law of the State of Delaware Law ("Delaware Law"), and no Holder of
Series F Preferred Stock shall vote or otherwise participate in any proceeding
in which actions shall be taken by the Company or the shareholders thereof or be
entitled to notification as to any meeting of the shareholders.

         Notwithstanding the above, Company shall provide Holder with
notification of any meeting of the shareholders regarding any major corporate
events affecting the Company. In the event of any taking by the Company of a
record of its shareholders for the purpose of determining shareholders who are
entitled to receive payment of any dividend or other distribution, any right to
subscribe for, purchase or otherwise acquire any share of any class or any other
securities or property (including by way of merger, consolidation or
reorganization), or to receive any other right, or for the purpose of
determining shareholders who are entitled to vote in connection with any
proposed sale, lease or conveyance of all or substantially all of the assets of
the Company, or any proposed liquidation, dissolution or winding up of the
Company, the Company shall mail a notice to Holder, at least ten (10) days prior
to the record date specified therein, of the date on which any such record is to
be taken for the purpose of such dividend, distribution, right or other event,
and a brief statement regarding the amount and character of such dividend,
distribution, right or other event to the extent known at such time.

         To the extent that under Delaware Law the vote of the Holders of the
Series F Preferred Stock, voting separately as a class, is required to authorize
a given action of the Company, the affirmative vote or consent of the Holders of
at least a majority of shares of the Series F Preferred Stock represented at a
duly held meeting at which a quorum is present or by written consent of a
majority of the shares of Series F Preferred Stock (except as otherwise may be
required under Delaware Law) shall constitute the approval of such action by the
class. To the extent that under Delaware Law the Holders of the Series F
Preferred Stock are entitled to vote on a matter with holders of Common Stock,
voting together as one (1) class, each share of Series F Preferred Stock shall
be entitled to a number of votes equal to the number of shares of Common Stock
into which it is then convertible using the record date for the taking of such
vote of stockholders as the date as of which the Conversion Price is calculated.
Holders of the Series F Preferred Stock also shall be entitled to notice of all
shareholder meetings or written consents with respect to which they would be
entitled to vote, which notice would be provided pursuant to the Company's
by-laws and applicable statutes.


                                       13
<PAGE>   17
         Section 9. Prospective Provision. So long as shares of Series F
Preferred Stock are outstanding, the Company shall not without first obtaining
the approval (by vote or written consent, as provided by Delaware Law) of the
Holders of at least seventy-five (75%) of the then outstanding shares of Series
F Preferred Stock, and at least seventy-five (75%) of the then outstanding
Holders:

            (a) alter or change the rights, preferences or privileges of the
Series F Preferred Stock or any Senior Securities so as to affect adversely the
Series F Preferred Stock; provided, however, that no such change may be approved
at any time on or prior to the fortieth (40th) day following the Last Closing
Date unless such change is unanimously approved by all Holders;

            (b) create any new class or series of stock having a preference over
the Series F Preferred Stock with respect to Distributions (as defined in
Section 2 above) or increase the size of the authorized number of Series F
Preferred; or

            (c) do any act or thing not authorized or contemplated by this
Certificate of Designation which would result in taxation of the holders of
shares of the Series F Preferred Stock under Section 305 of the Internal Revenue
Code of 1986, as amended (or any comparable provision of the Internal Revenue
Code as hereafter from time to time amended).

         In the event Holders of at least seventy-five percent (75%) of the then
outstanding shares of Series F Preferred Stock and at least seventy-five percent
(75%) of the then outstanding Holders agree to allow the Company to alter or
change the rights, preferences or privileges of the shares of Series F Preferred
Stock, pursuant to subsection (a) above, so as to affect the Series F Preferred
Stock, then the Company will deliver notice of such approved change to the
Holders of the Series F Preferred Stock that did not agree to such alteration or
change (the "Dissenting Holders") and Dissenting Holders shall have the right
for a period of thirty (30) business days to convert pursuant to the terms of
this Certificate of Designation as they exist prior to such alteration or change
(notwithstanding the provisions of Section 5(f) hereof), or continue to hold
their shares of Series F Preferred Stock provided, however, that the Dissenting
Holders may not convert anytime on or before the fortieth (40th) day following
the Last Closing Date.

         Section 10. Status of Converted or Redeemed Stock. In the event any
shares of Series F Preferred Stock shall be converted or redeemed pursuant to
Section 5 or Section 6 hereof, the shares so converted or redeemed shall be
canceled, shall return to the status of authorized but unissued Preferred Stock
of no designated series, and shall not be issuable by the Company as Series F
Preferred Stock.

         Section 11. Preference Rights. Nothing contained herein shall be
construed to prevent the Board of Directors of the Company from issuing one or
more series of Preferred Stock with


                                       14
<PAGE>   18
dividend and/or liquidation preferences junior to or on parity with the dividend
and liquidation preferences of the Series F Preferred Stock.

Dear Sirs:

     This letter sets forth certain amendments to (i) the Note Purchase
Agreement dated as of June 25, 1997 (the "Original Note Purchase Agreement"),
among Lasertechnics, Inc., a Delaware corporation (the "Company"), Antiope
Partners L.L.C. (formerly, Wolfensohn Partners, L.P.) ("Partners") and J.P.
Morgan Investment Corporation ("JPMIC"), which Note Purchase Agreement was
assigned by Antiope Partners L.L.C. to Amphion Ventures L.P. (formerly
Wolfensohn Associates II L.P.) ("Ventures II") by Assignment Agreement dated as
of August 19, 1997 and (ii) the several Senior Promissory Notes issued and sold
by the Company pursuant to the Original Note Purchase Agreement. Capitalized
terms used herein and not otherwise defined are used as defined in the Original
Note Purchase Agreement, as modified and amended herein.

     NOW, THEREFORE, in consideration of the mutual agreements contained herein
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto, intending to be bound hereby,
hereby agree to amend the Original Note Purchase Agreement, the Senior
Promissory Notes and the Pledge Agreement, as follows:

     1.  EXTENSION OF FINAL MATURITY DATE.  The Final Maturity Date under the
Note Purchase Agreement and each of the Senior Promissory Notes is hereby
extended to December 31, 1998, for all purposes of the Note Purchase Agreement,
the Senior Promissory Notes and the Pledge Agreement, except as expressly
provided in paragraph 2 of this Amendment to Note Purchase Agreement.

     2.  ADDITIONAL CONSIDERATION.  Notwithstanding the extension of the Final
Maturity Date as provided herein, on December 31, 1997, the Company shall pay
and deliver to each registered holder of the Senior Promissory Notes the
additional consideration provided for in paragraph 7 of the Original Note
Purchase Agreement, with respect to any and all Senior Promissory Notes
outstanding on such date.

     3.  RIGHT TO EXCHANGE NOTES.  The exchange right set forth in paragraph 9
of the Original Note Purchase Agreement is hereby terminated, and the Original
Note Purchase Agreement is hereby amended to delete such paragraph 9 in its
entirety.

     4.  MISCELLANEOUS.  (a)  Except to the extent modified and amended herein,
the terms and provisions of the Original Note Purchase Agreement, Senior
Promissory Notes and Pledge Agreement shall remain in full force and effect as
originally executed. All references in the Senior Promissory Notes, the Pledge
Agreement or any other instrument or agreement to the Note Purchase Agreement
shall be deemed for all purposes to refer to the Note Purchase Agreement as
amended hereby.

     (b) This Amendment and the amendments and modifications provided for
herein shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and permitted assigns.

     (c) This Amendment may be executed in any number of counterparts and on
separate counterparts, each of which shall be an original instrument, but all
of which together shall constitute a single agreement. One or more signature
pages from any counterpart of this Amendment may be attached to any other
counterpart of this Amendment without in any way changing the effect thereof.
This Amendment shall be effective as to each of the undersigned, severally,
when executed and delivered by the Company and such signatory.

     (d) The Company, Partners and Ventures II acknowledge that this letter
agreement is being executed by them, and is effective as between them
(notwithstanding anything in the original Note Purchase Agreement to the
contrary), prior to its execution by JPMIC. If this letter agreement is not
executed by JPMIC within thirty days after the date hereof, the Company,
Partners and Ventures II will negotiate with each other in good faith with
respect to an appropriate modification to this letter agreement. If any
modifications to the terms of this letter agreement are made in connection with
the execution hereof by JPMIC, and such terms are more favorable to JPMIC, the
Company agrees to amend this letter so that it is on substantially the same
terms as the letter with JPMIC.

request of the Obligor or with respect to which the Obligor's agreements
hereunder have been required by Bank, and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged by the Obligor, the

1.    Security Interest; Right of Set-Off. As security for the prompt and
      unconditional payment of any and all Obligations, the Obligor does hereby
      grant to Bank a continuing lien upon and security interest in, and does
      hereby pledge, assign and transfer to Bank, all of the Collateral. In

      given a continuing lien upon and is granted a security interest in any
      and all monies, securities and any and all other property of the Obligor
      and the proceeds thereof, now or hereafter actually or constructively

      collateral security), or coming into the possession of Bank or its
      correspondents or agents in any way, or placed in any safe deposit box
      leased by Bank to the Obligor, and all such monies, securities and other
      property shall also constitute "Collateral" and shall be held subject to
      all the terms of this Agreement as collateral security for the prompt and
      unconditional payment of any and all Obligations. Obligor hereby assigns
      and grants Bank a security interest in, and Bank is also given a
      continuing lien on and/or right of set-off for the amount of the
      Obligations with respect to, any and all deposits (general or special)
      and credits of the Obligor with, and any and all claims of the Obligor
      against, Bank at any time existing, and Bank is hereby authorized at any
      time or times, without prior notice, to apply such deposit or credits, or
      any part thereof, to the Obligations in such amounts as Bank may elect,
      although the Obligations may be contingent or unmatured, and whether the
      collateral security therefor is deemed adequate or not.                 

2.    Representations of Obligor. The Obligor represents and warrants to bank
      that (a) no financing statement or other filing listing any of the
      Collateral as collateral is on file in any jurisdiction (other than any
      financing statement filed on behalf of Bank, as secured party); (b) the

      set forth in the space provided therefor in this Agreement; (c) all

      office specified herein, if any, and the Collateral Location(s); (d) the
      Obligor has not created and is not aware of any Lien on or affecting any
      Collateral other than the lien created by this Agreement in favor of Bank;
      (e) if the Obligor is not a natural person, the execution, delivery and
      performance of this Agreement have been duly authorized by all required
      corporate, partnership or other applicable actions of the Obligor; (f)
      this Agreement constitutes a valid, binding and enforceable obligation of
      the Obligor; (g) the execution, delivery and performance of this Agreement
      do not violate any law or any agreement or undertaking to which the
      Obligor is a party or by which the Obligor may be bound and do not result
      in the imposition of any Lien upon any Collateral other than the Lien in
      favor of Bank created by this Agreement; (h) all consents, approvals,
      authorizations, permits and licenses necessary for the Obligor to enter
      and perform its obligations under this Agreement and the Obligations
      and/or to conduct its business have been obtained; (i) the Obligor did not
      have or conduct business under any name or trade name in any jurisdiction
      during the past six years other than its name and trade names, if any, set
      forth on the signature page of this Agreement, and the Obligor is entitled
      to use such name and trade names; and (j) the Obligor is the legal and

      this Agreement (alongside the box designated "Specific Property") and any
      Collateral specifically identified in any rider, schedule or exhibit to
      this Agreement.

3.    Covenants. Unless and until all of the Obligations have been indefeasibly
      paid in full and all commitments of Bank to extend credit which, once
      extended, would give rise to Obligations, have expired or been terminated,
      the Obligor shall: (a) keep the Collateral free and clear of any Lien of
      any kind other than the Lien created by this Agreement; (b) promptly pay,
      when due, all taxes and transportation, storage,

      the expense of the Obligor to Bank's satisfaction against loss by fire,

      each insurer will give Bank not less than 30 days' notice in writing prior
      to the exercise of any right of cancellation; (d) keep the Collateral in
      good condition at all times (normal wear and tear excepted) and provide

            of Bank or in the name of the Obligor, of any or all of the
            Accounts, contractual and other rights that are included in the
            Collateral and Proceeds by suit or otherwise, receive, receipt for,
            surrender, release or exchange all or any part of such Collateral or
            compromise, settle, extend or renew (whether or not longer than the
            original period) any indebtedness under such Collateral; (v) sell
            all or any part of the Collateral at public or private sale at such
            place or places and at such time or times and in such manner and
            upon such terms, whether for cash or credit, as Bank in its sole
            discretion may determine; (vi) endorse in the name of the Obligor
            any Instrument, however received by Bank, representing Collateral or
            Proceeds of any of the Collateral; (vii) require the Obligor to turn
            over, or instruct the financial institutions holding the same to
            turn over, all monies and investments in any of Obligor's accounts
            to Bank; and (viii) exercise all the rights and remedies granted to
            a secured party under the New York Uniform Commercial Code and all
            other rights and remedies given to Bank under this Agreement or any
            other instrument or agreement or otherwise available at law or in
            equity. Bank shall be under no obligation to make any of the
            payments or do any of the acts referred to in this Section 5 or
            elsewhere in this Agreement and any of the actions referred to in
            this Section 5 or elsewhere in this Agreement may be taken
            regardless of whether any notice of default or election to sell has
            been given under this Agreement (provided, however, that all notices
            required by law, the giving of which may not be waived, shall be
            given in accordance with such law) without regard to the adequacy of
            the security for the Obligations.

      (d)   The Obligor hereby waives notice of the sale of any Collateral by
            Bank pursuant to any provision of this Agreement or any applicable
            provisions of the Uniform Commercial Code or other applicable law.
            In the event that notice of the sale of Collateral cannot be waived
            or Bank gives notice of such sale to the Obligor, Bank will give the
            Obligor notice of the time and place of any public sale of the
            Collateral or of the time after which any private sale or any other
            intended disposition thereof is to be made by sending notice, as
            provided below, at least five days before the time of the sale or
            disposition, which provisions for notice the Obligor and Bank agree
            are reasonable. No such notice need be given by Bank with respect to
            Collateral which is perishable or threatens to decline speedily in
            value or is of a type customarily sold on a recognized market.

      (e)   Bank may apply the net proceeds of any sale, lease or other
            disposition of Collateral, after deducting all costs and expenses
            of every kind incurred thereon or incidental to the retaking,
            holding, preparing for sale, selling, leasing or the like of the
            Collateral or in any way relating to the rights of Bank thereunder,
            including attorneys' fees and expenses hereinafter provided for, to
            the payment, in whole or in part, in such order as Bank may elect,
            of one or more of the Obligations, whether due or not due, absolute
            or contingent, making proper rebate for interest or discount on
            items not then due, and only after so applying such net proceeds
            and after the payment by Bank of any other amounts required by any
            existing or future provision of law (including Section 9-504(l)(c)
            of the Uniform Commercial Code of any jurisdiction in which any of
            the Collateral may at the time be located) need Bank account for
            the surplus, if any. The Obligor shall remain liable to Bank for
            the payment of any deficiency, with interest at the default rate
            provided for in the instruments, if any, evidencing the
            Obligations, but if there is no such instrument with respect to any
            Obligation or no default rate is specified therein, at a variable
            rate equal to 4% above the Bank's reference lending rate applicable
            to domestic commercial loans as established by Bank from time to
            time, but in no event shall such rate exceed the maximum rate
            allowed by law. Bank may make loans to its customers above, at or
            below its reference rate.
        
      (f)   Whether or not an Event of Default shall have occurred, Bank may
            sell all or any part of the Collateral, although the Obligations may
            be contingent or unmatured, whenever in its discretion Bank
            considers such sale necessary for its protection. Any such sale may
            be made without prior demand for payment on account, margin or
            additional margin or any other demands whatsoever; the making of any
            such demands shall not establish a course of conduct nor constitute
            a waiver of the right of Bank to sell the Collateral as herein
            provided or of the right of Bank to accelerate the maturity of the
            Obligations as herein provided.

6.    Additional Rights of Bank and Duties of Obligor Regarding Obligations and
      Collateral.

      (a)   If the Obligor, as registered holder of any Collateral, shall become
            entitled to receive or does receive any stock certificate, option or
            right, whether as an addition to, in substitution of, or in exchange
            for, such Collateral, or otherwise, the Obligor agrees to accept
            same as Bank's agent and to hold same in trust for Bank, and to
            forthwith deliver the same to Bank in the exact form


                                       5
<PAGE>   6

            received, with the Obligor's endorsement when necessary or requested
            by Bank, to be held by Bank as Collateral.

      (b)   The Obligor waives protest demand for payment, notice of default or
            nonpayment to the Obligor or any other party liable for or upon any
            of said Obligations or Collateral.

      (c)   The Obligor consents that the obligation of any party upon or of any
            guarantor, surety or indemnitor for any Obligations or any
            Collateral may, from time to time, in whole or in part, be renewed,
            extended, modified, accelerated, compromised, settled or released
            and that any Collateral or Liens for any Obligations may, from time
            to time, in whole or in part, be exchanged, sold, released or
            surrendered, by Bank, all without any notice to, or further assent
            by, or any reservation of rights against, the Obligor, and all
            without in any way affecting or releasing the liability of the
            Obligor with respect to such Obligations or any security interest
            hereby created.

      (d)   Bank shall not be liable for failure to collect or realize upon the
            Obligations or upon the Collateral, or any part thereof, or for any
            delay in so doing, nor shall Bank be under any obligation to take
            any action whatsoever with regard thereto. Bank shall use
            reasonable care in the custody and preservation of the Collateral
            in its possession but need not take any steps to preserve rights
            against prior parties or to keep the Collateral identifiable. Bank
            shall have no obligation to comply with any recording,
            re-recording, filing, re-filing or other legal requirements
            necessary to establish or maintain the validity, priority or
            enforceability of, or Bank's rights in and to the Collateral or any
            part thereof. Bank may exercise any right of the Obligor with
            respect to any Collateral. Bank shall have no duty to exercise any
            of the aforesaid rights, privileges or options with respect to any
            Collateral and shall not be responsible for any failure to do so or 
            delay in so doing.                                                 

      (e)   In any statutory or non-statutory proceeding affecting the Obligor
            or any Collateral, Bank or its nominee may, whether or not an Event
            of Default shall have occurred and regardless of the amount of the
            Obligations, file a proof of claim for the full amount of any
            Collateral and vote such Claim for the full amount thereof (i) for
            or against any proposal or resolution; (ii) for a trustee or
            trustees or for a committee of creditors; and/or (iii) for the
            acceptance or rejection of any proposed arrangement, plan of
            reorganization, wage earners' plan, composition or extension; and
            Bank or its nominee may receive any payment or distribution and give
            acquittance therefor and may exchange or release any Collateral.

      (f)   Whether or not an Event of Default shall have occurred, Bank may,
            without notice to or demand upon the Obligor, (i) commence, appear
            in or defend any action or proceeding purporting to affect all or
            any part of the Collateral or the interests, rights, powers or
            duties of Bank, whether brought by or against the Obligor or Bank;
            and/or (ii) pay, purchase, contest or compromise any claim, debt,
            lien, charge or encumbrance which in the judgment of Bank may affect
            or appear to affect the Collateral or the interests, rights, powers
            or duties of Bank.

      (g)   Any and all stocks, bonds or other securities held by Bank as
            Collateral hereunder may, without notice (and whether or not a
            default exists), be registered in the name of Bank or its nominee
            without disclosing that Bank is a pledgee. Bank (whether or not a
            default exists and regardless of the amount of the Obligations) or
            its nominee may, without notice, exercise all voting and corporate
            rights at any meeting of any corporation issuing such stocks, bonds
            or other securities, and exercise any and all rights of conversion,
            exchange, subscription or any other rights, privileges or options
            pertaining to such stocks, bonds or other securities as if the
            absolute owner thereof, including, without limitation, the right to
            exchange, at its discretion, any and all of such stocks, bonds or
            other securities for other stocks, bonds, securities or any other
            property upon the merger, consolidation, reorganization,
            recapitalization or other readjustment of any corporation issuing
            the same or upon the exercise by the issuing corporation or Bank of
            any right, privilege or option pertaining to such stocks, bonds or
            other securities, and in connection therewith, to deposit and
            deliver any and all of such stocks, bonds or other securities with
            any committee, depositary, transfer agent, registrar or other
            designated agency upon such terms and conditions as it may
            determine, all without liability except to account for property
            actually received by it. Bank shall have no duty to exercise any of
            the aforesaid rights, privileges or options and shall not be
            responsible for any failure to do so or for any delay in so doing.

7.    Sale of Collateral Consisting of Securities. The Obligor recognizes that
      Bank may be unable to effect a public sale of any securities which may
      constitute a portion of the Collateral by reason of certain


                                       6
<PAGE>   7

      prohibitions contained in the Securities Act of 1933 and applicable state
      securities laws and instead may resort to one or more private sales of
      such Collateral to a restricted group of purchasers who would be obliged
      to agree, among other things, to acquire such securities for their own
      account for investment and not with a view to the distribution or resale
      thereof. The Obligor recognizes and agrees that, because of this
      restriction, sales of securities may result in prices and other terms less
      favorable to the seller than if the disposition were made pursuant to a
      public sale and, notwithstanding such circumstances, agrees that any such
      private or limited sale or sales shall be deemed to have been made in a
      commercially reasonable manner. Bank shall be under no obligation to delay
      a sale of any of the securities constituting part of the Collateral for
      the period of time necessary to permit the issuer of such securities to
      register them for public sale under the Securities Act of 1933 or under
      applicable state securities laws.

8.    Collection Rights of Bank. The Obligor agrees that at any time, whether or
      not an Event of Default shall have occurred, Bank shall have the right to
      notify an account debtor (with respect to any Collateral consisting of
      Accounts), or the obligor on any Instrument or other right or claim of the
      Obligor to any payment which is Collateral, to make payment directly to
      Bank, whether or not an Event of Default shall have occurred and whether
      or not the Obligor was theretofore making collections on such Collateral,
      and also to take control of any Proceeds Bank is entitled to under Section
      9-306 of the New York Uniform Commercial Code. If any Collateral consists
      of Accounts, Instruments or other rights or claims of the Obligor to any
      payment, then at Bank's request, the Obligor shall promptly notify (in
      manner, form and substance satisfactory to Bank) all Persons obligated to
      the Obligor under any such Accounts, Instruments or other rights or claims
      of the Obligor to any payment that Bank possesses a security interest in
      such Accounts, Instruments or other rights or claims of the Obligor to any
      payment and that all payments in respect of such Accounts, Instruments or
      other rights or claims of the Obligor to any payment are to be made
      directly to Bank. The Obligor shall not settle, compromise or adjust any
      disputed amount, or allow any credit, rebate or discount with respect to
      any Account, Instrument or other right or claim of the Obligor to any
      payment which constitutes Collateral. After Bank shall have given any
      notice of the type specified in the first sentence of this Section 8, any
      and all amounts received by the Obligor from the account debtor or other
      obligor so notified shall be promptly remitted to Bank, and until so
      remitted shall be segregated by the Obligor and held in trust for Bank.

9.    Additional Security. If Bank shall at any time hold security for any
      Obligations in addition to the Collateral, Bank may enforce the terms of
      this Agreement or otherwise realize upon the Collateral, at its option,
      either before or concurrently with the exercise of remedies as to such
      other security or, after a sale is made of such other security, it may
      apply the proceeds upon the Obligations without affecting the status of or
      waiving any right to exhaust all or any other security, including the
      Collateral, and without waiving any breach or default or any right or
      power whether exercised under this Agreement, contained in this Agreement,
      or provided for in respect of any such other security.

10.   Preservation and Protection of Security Interest; Power of Attorney. The
      Obligor will faithfully preserve and protect the Lien in the Collateral
      created by this Agreement and will, at its own cost and expense, cause
      such Lien to be perfected and continue to be perfected and to be and
      remain prior to all other Liens, so long as all or any part of the
      Obligations are outstanding and unpaid, and for such purpose the Obligor
      will from time to time at the request of Bank (i) make notations of the
      security interest in certificates of title of Collateral, a security
      interest in which is perfected by such notation, and deliver the same to
      Bank, (ii) deliver possession of Collateral (concurrent with the
      acquisition of such Collateral) to Bank, a security interest in which is
      perfected by the taking of possession, and (iii) file or record, or cause
      to be filed or recorded, such instruments, documents and notices,
      including financing statements and continuation statements, as Bank may
      reasonably deem necessary or advisable from time to time in order to
      perfect and continue to perfect such Liens and to maintain their priority
      over all other Liens. The Obligor will do all such other acts and things
      and will execute and deliver all such other instruments and documents,
      including further security agreements, pledges, endorsements, assignments,
      and notices as Bank may reasonably deem necessary or advisable from time
      to time in order to perfect and preserve the priority of the Liens in the
      Collateral as contemplated by this Agreement. Bank, acting through its
      officers, employees and authorized agents, is hereby irrevocably appointed
      the attorney-in-fact of the Obligor to do, at the Obligor's expense, all
      acts and things which Bank may reasonably deem necessary or advisable to
      preserve, perfect, continue to perfect and/or maintain the priority of
      such Liens in the Collateral, including the signing of financing,
      continuation or other similar statements and notices on behalf of the
      Obligor, and which the Obligor is required to do by the terms of this
      Agreement. The Obligor hereby authorizes Bank to sign and file financing
      statements with respect to the Collateral without the signature of the
      Obligor. The Obligor shall pay all filing fees for financing statements
      with respect to the Collateral.


                                       7
<PAGE>   8

11.   Risk of Loss; Insurance. Risk of loss of, damage to or destruction of the
      Collateral is and shall remain upon the Obligor. If the Obligor fails to
      obtain and keep in force insurance covering the Collateral as required by
      Section 3 of this Agreement, or fails to pay the premiums on such
      insurance when due, Bank may, but is not obligated to, do so for the
      account of the Obligor and the cost of so doing shall thereupon become an
      Obligation. Such amounts shall be payable by the Obligor upon demand by
      the Bank and following demand shall bear interest at a variable rate equal
      to 4% above the Bank's reference lending rate applicable to domestic
      commercial loans as established by Bank from time to time, but in no event
      shall such rate exceed the maximum rate allowed by law. Bank, acting
      through its officers, employees and authorized agents, is hereby
      irrevocably appointed the attorney-in-fact of the Obligor to endorse any
      draft or check that may be payable to the Obligor in order to collect the
      proceeds of such insurance or any return or unearned premiums.

12.   Change in Law. In the event of the passage, after the date of this
      Agreement, of any law which has the effect of changing in any way the laws
      now in force for the taxation of security documents such as this Agreement
      or debts secured by such security documents or the manner of the
      collection of any such taxes so as in any case to affect this Agreement or
      to impose payment of the whole or any portion of any taxes, assessments or
      other similar charges against the Collateral upon Bank, the Obligations
      shall immediately become due and payable at the option of Bank and upon 30
      days notice to the Obligor.

13.   Expenses. The Obligor hereby agrees to pay any and all expenses incurred
      by Bank in enforcing any rights under this Agreement or in defending any
      of its rights to any amounts received hereunder. Without limiting the
      foregoing, the Obligor agrees that whenever any attorney is used by Bank
      to obtain payment hereunder, to advise it as to its rights, to adjudicate
      the rights of the parties hereunder or for the defense of any of its
      rights to amounts secured, received or to be received hereunder, Bank
      shall be entitled to recover all reasonable attorneys' fees and
      disbursements, court costs and all other expenses attributable thereto.

14.   Notices. Each notice or other communication hereunder shall be in writing,
      shall be sent by messenger, by registered or certified mail or by

      Obligor herein. Bank may assign all or a portion of its rights under this
      Agreement and may deliver the Collateral, or any part thereof, to any
      assignee and such assignee shall thereupon become vested with all the
      powers and rights given to Bank in respect thereof; and Bank shall
      thereafter be forever relieved and discharged from any liability or
      responsibility in the matter but, with respect to any Collateral not so
      delivered or assigned, Bank shall retain all powers and rights given to it
      hereby. The execution and delivery hereafter to Bank by the Obligor of a
      new security agreement shall not terminate, supersede or cancel this
      Agreement, unless expressly provided therein, and this Agreement shall not
      terminate, supersede or cancel any security agreement previously delivered
      to Bank by the Obligor, and all rights and remedies of Bank hereunder or
      under any security agreement hereafter or heretofore executed and
      delivered to Bank by the Obligor shall be cumulative and may be exercised
      singly or concurrently. This Agreement may not be changed or terminated
      orally, but only by a writing executed by the Obligor and a duly
      authorized officer of Bank. Unless Bank, in its discretion, otherwise
      agrees, the security interests granted in this Agreement shall not
      terminate until all of the Obligations have been indefeasibly paid in full
      and all commitments of Bank to extend credit which, once extended, would
      give rise to Obligations have expired or been terminated. No delay on the
      part of Bank in exercising any of its options, powers or rights, or
      partial or single exercise thereof, shall constitute a waiver thereof. No
      modification or waiver of this Agreement or any provision hereof or of any
      other agreement or instrument made or issued in connection herewith or
      contemplated hereby, nor consent to any departure by the Obligor
      therefrom, shall in any event be effective, irrespective of any course of
      dealing between the parties, unless the same shall be in a writing
      executed by a duly authorized officer of Bank, and then such waiver or
      consent shall be effective only in the specific instance and for the
      specific purpose for which given. No notice to or demand on the Obligor in
      any case shall thereby entitle the Obligor to any other or further notice
      or demand in the same, similar or other circumstances. The remedies herein
      provided are cumulative and not exclusive of any other remedies provided
      at equity or by law and all such remedies may be exercised singly or
      concurrently. If any one or more of the provisions contained in this
      Agreement or any document executed in connection herewith shall be
      invalid, illegal or unenforceable in any respect under any applicable law,
      the validity, legality and enforceability of the remaining provisions
      contained herein shall not (to the full extent permitted by law) in any
      way be affected or impaired. The descriptive headings used in this
      Agreement are for convenience only and shall not be deemed to affect the
      meaning or construction of any provision hereof. The word "including"
      shall be deemed to be followed by the words "without limitation." The
      Obligor waives any and all notice of the acceptance of this Agreement by
      Bank, or of the creation, accrual or maturity (whether by declaration or
      otherwise) of any and all Obligations, or of any renewals or extensions
      thereof from time to time, or of Bank's reliance on this Agreement.

17.   Governing Law; Consent to Jurisdiction; Service of Process. This Agreement
      shall be governed by and construed in accordance with the laws of the
      State of New York applicable to contracts made and to be performed wholly
      within that state. The Obligor hereby consents to the jurisdiction of the
      courts of the State of New York and the courts of the United States of
      America for the Southern District of New York and consents that any action
      or proceeding hereunder may be brought in such courts, and waives any
      objection that it may now or hereafter have to the venue of any such
      action or proceeding in any such court or that such action or proceeding
      was brought in an inconvenient court and agrees not to plead or claim the
      same; and authorizes the service of process on the Obligor by registered
      or certified mail sent to any address authorized in Section 14 as an
      address for the sending of notices.

18.   RIGHT OF BANK TO ARBITRATE DISPUTES.

      (a)   THE OBLIGOR AGREES THAT ANY ACTION, DISPUTE, PROCEEDING, CLAIM OR
            CONTROVERSY BETWEEN OR AMONG THE PARTIES WHETHER SOUNDING IN
            CONTRACT, TORT OR OTHERWISE ("DISPUTE" OR "DISPUTES") SHALL, AT
            BANK'S ELECTION, WHICH ELECTION MAY BE MADE AT ANY TIME PRIOR TO THE
            COMMENCEMENT OF A JUDICIAL PROCEEDING BY BANK, OR IN THE EVENT OF A
            JUDICIAL PROCEEDING INSTITUTED BY THE OBLIGOR AT ANY TIME PRIOR TO
            THE LAST DAY TO ANSWER AND/OR RESPOND TO A SUMMONS AND/OR COMPLAINT
            MADE BY THE OBLIGOR, BE RESOLVED BY ARBITRATION IN NEW YORK, NEW
            YORK IN ACCORDANCE WITH THE PROVISIONS OF THIS SECTION 18 AND SHALL,
            AT THE ELECTION OF BANK, INCLUDE ALL DISPUTES ARISING OUT OF OR IN
            CONNECTION WITH (I) THIS AGREEMENT OR ANY RELATED AGREEMENTS OR
            INSTRUMENTS, (II) ALL PAST, PRESENT AND FUTURE AGREEMENTS INVOLVING
            THE PARTIES, (III) ANY TRANSACTION CONTEMPLATED HEREBY AND ALL PAST,
            PRESENT AND FUTURE TRANSACTIONS INVOLVING THE PARTIES AND (IV) ANY
            ASPECT OF THE PAST, PRESENT OR FUTURE RELATIONSHIP OF THE PARTIES.
            Bank may elect to require arbitration of any Dispute with the
            Obligor without thereby being required to arbitrate all Disputes
            between Bank and the Obligor. Any such Dispute shall be resolved by
            binding arbitration in accordance with Article 75 of the New York
            Civil Practice Law and Rules and the Commercial Arbitration Rules of
            the American Arbitration Association ("AAA"). In the event of any
            inconsistency between such Rules and these arbitration provisions,
            these provisions shall supersede such Rules. All statutes of
            limitations which would otherwise be applicable shall apply to any
            arbitration proceeding under this subsection 18(a). In any
            arbitration proceeding subject to these provisions, the arbitration
            panel (the "arbitrator") is specifically empowered to decide (by
            documents only, or with a hearing, at the arbitrator's sole
            discretion) pre-hearing motions which are substantially similar to
            pre-hearing motions to dismiss and motions for summary adjudication.
            In any such arbitration proceeding, the arbitrator shall not have
            the power or authority to award punitive damages to any party.
            Judgment upon the award rendered may be entered in any court having
            jurisdiction. Whenever an arbitration is required, the parties shall
            select an arbitrator in the manner provided in subsection 18(d).

      (b)   No provision of, nor the exercise of any rights under, subsection
            18(a) shall limit the right of any party (i) to foreclose against
            any real or personal property collateral through judicial
            foreclosure, by the exercise of a power of sale under a deed of
            trust, mortgage or other security agreement or instrument, pursuant
            to applicable provisions of the Uniform Commercial Code, or
            otherwise pursuant to applicable law, (ii) to exercise self help
            remedies including but not limited to setoff and repossession, or
            (iii) to request and obtain from a court having jurisdiction before,
            during or after the pendency or any arbitration, provisional or
            ancillary remedies and relief including but not limited to
            injunctive or mandatory relief or the appointment of a receiver. The
            institution and maintenance of an action or judicial proceeding for,
            or pursuit of, provisional or ancillary remedies or exercise of self
            help remedies shall not constitute a waiver of the right of Bank,
            even if Bank is the plaintiff, to submit the Dispute to arbitration
            if Bank would otherwise have such right.

      (c)   Bank may require arbitration of any Dispute(s) concerning the
            lawfulness, unconscionableness, propriety, or reasonableness of any
            exercise by Bank of its right to take or dispose of any Collateral
            or its exercise of any other right in connection with Collateral
            including, without limitation, judicial foreclosure, exercising a
            power of sale under a deed of trust or mortgage, obtaining or
            executing a writ of attachment, taking or disposing of property with
            or without


                                       10
<PAGE>   11

            judicial process pursuant to Article 9 of the Uniform Commercial
            Code or otherwise as permitted by applicable law, notwithstanding
            any such exercise by Bank.

      (d)   Whenever an arbitration is required under subsection 18(a), the
            arbitrator shall be selected, except as otherwise herein provided,
            in accordance with the Commercial Arbitration Rules of the AAA. A
            single arbitrator shall decide any claim of $100,000 or less and he
            or she shall be an attorney with at least five years' experience.
            Where the claim of any party exceeds $100,000, the Dispute shall be
            decided by a majority vote of three arbitrators, at least two or
            whom shall be attorneys (at least one of whom shall have not less
            than five years' experience representing commercial banks).

      (e)   In the event of any Dispute governed by this Section 18, each of the
            parties shall, subject to the award of the arbitrator, pay an equal
            share of the arbitrator's fees. The arbitrator shall have the power
            to award recovery of all costs and fees (including attorneys' fees,
            administrative fees, arbitrators' fees, and court costs) to the
            prevailing party.

19.   WAIVER OF TRIAL BY JURY. EACH OF BANK AND THE OBLIGOR HEREBY WAIVES TRIAL
      BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY OR AGAINST IT
      ON ANY MATTERS WHATSOEVER, IN CONTRACT OR IN TORT, ARISING OUT OF OR IN
      ANY WAY CONNECTED WITH THIS AGREEMENT OR THE OBLIGATIONS.

20.   WAIVER OF CERTAIN OTHER RIGHTS. THE OBLIGOR HEREBY WAIVES THE RIGHT TO
      INTERPOSE ANY DEFENSE BASED UPON ANY CLAIMS OF LACHES OR SET-OFF OR
      COUNTERCLAIM OF ANY NATURE OR DESCRIPTION, ANY OBJECTION BASED ON FORUM
      NON CONVENIENS OR VENUE, AND ANY CLAIM FOR CONSEQUENTIAL, PUNITIVE OR
      SPECIAL DAMAGES.

      IN WITNESS WHEREOF, the Obligor(s) has/have executed this Continuing
General Security Agreement.

                            AMENDED MARGIN AGREEMENT

      Rider to Continuing General Security Agreement (dated December 5, 1996
from Wolfensohn Associates L.P., Obligor, in favor of the Bank (as defined
therein)).

      Reference is made to the heading "Specific Property" referred to in this
      Continuing General Security Agreement and to the securities ("Marketable
      Securities") of the types described in Exhibit A, attached hereto, and to
      any renewals, substitutions or replacements and all proceeds thereof, from
      time to time held in Account No. 7771 or any successor account ("Account")
      referred to under such heading. Obligor acknowledges and agrees that the
      value of the Marketable Securities shall at all times have the Collateral
      Value, as defined below, at least equal to the Obligations. If at any time
      the Collateral Value is less than the Obligations (a "Margin Shortfall"),
      the Bank may give notice to the Obligor in accordance with Section 14
      hereof, at the address set forth below, that a Margin Shortfall exists and
      the amount of such Shortfall (the "Margin Shortfall Notice"). If within 15
      business days of the date of such Margin Shortfall Notice, the Obligor has
      neither (a) deposited with the Bank in the Account an amount equal to the
      amount set forth in the Margin Shortfall Notice of cash and/or additional
      Marketable Securities satisfactory to the Bank and approved by the Bank in
      writing or (b) prepaid an amount of the Obligations at least equal to the
      amount set forth in the Margin Shortfall Notice, then the Bank may, in
      its sole discretion, (x) sell such amount of Marketable Securities and
      apply the proceeds of such sale to the Obligations so as to cause the
      Obligations to cease to be less than the Collateral Value or (y) declare
      the Obligations immediately due and payable notwithstanding the absence of
      any default by the Borrower under the Obligations whereupon an Event of
      Default shall be deemed to have occurred hereunder and the Bank may sell
      the Marketable Securities and otherwise exercise its remedies hereunder or
      as are otherwise available to it. As used herein, the term "Collateral
      Value" shall mean the sum of any cash held in such Account and the sum of
      the respective products obtained by multiplying the fair market value, as
      determined by the Bank, of each type of Marketable Security held in such
      Account, by applicable percentage for such type of security set forth in
      Exhibit A hereto.

      This Margin Agreement amends and restates in the entirety the Margin

attached to the Continuing General Security Agreement.
