                                  WITNESSETH

In consideration of the premises, the parties covenant and agree as follows:

1.   Definitions.  As herein used:

     1.1    "Equipment" means the equipment manufactured or sold by the
            Manufacturers or Distributors described in the Schedule of Leased
            Equipment ("Schedule") annexed hereto and made a part hereof,
            together with any replacements or substitution of parts,
            improvements or additions thereto, and such other equipment which,
            by agreement, may from time to time be hereafter described on any
            supplemental schedule of leased equipment ("Schedule") which may
            be annexed hereto and made a part hereof (the equipment on all
            such schedules being collectively herein referred to as
            "Equipment"). The term "Equipment" also includes all software and
            other intellectual property described on the Schedule as well as
            operating software and application software used or usable in
            connection with any item set forth on any Schedule whether or not
            such software or other intellectual property is specifically
            identified on the Schedule, and also includes all tangible
            representations of all such software.

     1.2    "Commencement Date" means the first day of the calendar quarter
            following the delivery of all the Equipment.

     1.3    "Monthly Rent" means the amount of rent payable by Lessee each
            month pursuant to Paragraph 3 of the Schedule as well as all
            maintenance charges payable, if any, if, according to the
            Schedule, Lessor is furnishing maintenance as indicated on the
            Schedule.

     1.4    "Net Proceeds of Sale" means the net amount received by Lessor
            after deducting from the gross proceeds of sale of the Equipment
            or in the event of a subsequent lease by the Lessor, the net
            present value of rent due under such subsequent lease, all
            expenses incurred in the termination of this lease and any amounts
            for which, if not paid, Lessor would be liable or which, if not
            paid, would constitute a lien on the Equipment.

     1.5    "Lessor's Depreciated Book Value" means the original cost of the
            equipment less the straight line depreciation for five year
            property, all as reflected on Lessor's books of account.

     1.6    "Lease Term" means the period specified in Section 2 of the
            applicable Schedule thereof.

     1.7    "Addendum" means any amendment to this Master Equipment Lease
            which is specifically identified as such, and when so identified
            shall be a part hereof.

2.   Lessor does hereby lease to the Lessee, and Lessee hereby leases and
     hires from the Lessor the Equipment subject to the terms, provisions,
     conditions and agreements in this lease set forth.

3.   Delivery.  Lessee hereby acknowledges: (a) the Equipment is of the
     manufacture, design and capacity selected by Lessee; (b) the Equipment
     is suitable for Lessee's purposes, and (c) Lessor has made no
     representation or warranty, expressed or implied, with respect to the
     Equipment or any of the foregoing matters. Lessor will assign or
     otherwise make available to Lessee all of Lessor's rights (if any and if
     assignable) under the manufacturer's warranty on the Equipment and
     maintenance agreement relating thereto, all costs and charges thereof
     and therefore to be borne by Lessee.

     At the termination of the applicable Schedule, Lessee shall, at its
     expense, return the Equipment subject thereto to Lessor at the location
     designated by Lessor within the continental United States by surface
     transportation, only if not shipped directly to a successor Lessee. The
     Equipment returned to Lessor shall, at the time it is disconnected from
     its then location in Lessee's premises, be in the same condition and
     working order as when delivered to Lessee, reasonable wear and tear and
     casualty loss excepted, and shall be at the then current engineering
     change level recommended by the Equipment Manufacturer (if required in
     the Schedule).

4.   In addition to the Monthly Rent, Lessee shall pay, promptly when due,
     all costs, expenses, fees, charges and taxes incurred in connection with
     the use and operation of the Equipment. Such items shall include, but
     not be limited to:

     4.1.1  all costs of operating the Equipment.

     4.1.2  all federal, state, county, municipal or other taxes whatsoever,
            without proration, and any penalties and interest thereon
            ("Taxes") (including any Taxes with an assessment date which
            occurred during the Lease Term or any extension thereof). If the
            payment due date or reimbursement date for a Tax should occur
            after the expiration or termination of the Lease Term or any
            extension thereof, Lessee's liability for such Tax shall survive
            such expiration or termination.

     4.1.3  all shipping, installation, and transportation charges from the
            manufacturer or vendor to the installation site.

     4.1.4  all de-installation, shipping and transportation charges from the
            installation site to a location designated by the Lessor at the
            conclusion of the Lease or any extension thereof.

     4.2    If Lessee should fail to pay any of the costs, expenses, fees,
            charges and taxes (including attorney's fees) for which Lessee is
            liable hereunder, Lessor may, but shall not be required to, pay
            the same for the account



            of Lessee. Lessee shall reimburse, upon demand, for the full amount
            of any such costs, expenses, fees, charges and taxes paid by Lessor.

     4.3    If, at the termination of the applicable Schedule, Lessee fails to
            return to Lessor the Equipment subject thereto in accordance with
            the provisions of the second paragraph of Section 3, Lessee
            shall, until such Equipment is so returned: pay to Lessor on
            account of damages a monthly amount equal to the amount shown in
            Section 5 of such Schedule, and perform or observe all other of
            its agreements and covenants under this Lease; but such payment,
            performance, and observance shall not limit or impair Lessor's
            right to recover the Equipment or any other of Lessor's rights
            under this Lease, nor shall it represent an extension of the term
            provided in the applicable schedule, nor shall it represent a
            consent by the Lessor to such failure by Lessee to return, and,
            in all events notwithstanding such payment, performance and
            observance, Lessee's obligation so to return shall remain in full
            force and effect.

5.   Use of Equipment.  Lessee shall use the Equipment only for lawful
     purposes in the regular course of its business or the business of any
     subsidiary or affiliate of Lessee within the United States or its
     possessions.  Lessee shall, concurrently with the execution of this
     Lease, notify Lessor in writing where all Equipment is principally
     located, and upon any change in such principal location of any
     Equipment, notify Lessor in writing within ten (10) days thereafter of
     the new principal location of such Equipment.  Lessee shall use every
     reasonable precaution to prevent loss or damage to Equipment from fire
     and other hazards.  Lessee's servants and agents shall cooperate fully
     with Lessor in the investigation of any claims and suits relating to the
     Equipment.  Lessee shall keep the Equipment free from all liens and
     encumbrances.  This Lease and the interest of Lessee hereunder shall not
     be assigned, alienated, pledged or hypothecated voluntarily by Lessee or
     by operation of law, nor shall Lessee permit the Equipment to come into
     the possession of any third person except a subsidiary or affiliate of
     Lessee, provided, however, that Lessee shall remain obligated to Lessor
     hereunder with respect to any such Equipment.

6.   Lessee will enter into a Master Maintenance Agreement with Lessor.
     Except to the extent of the Lessor's obligation to provide maintenance
     (as provided in the aforesaid Master Maintenance Agreement) Lessee
     shall, at its own expense, keep the Equipment in first-class condition
     and repair and in good and efficient working order (including the
     replacement or substitution of parts, improvements or additions to the
     Equipment).  Lessee shall not, without Lessor's prior written consent,
     make any substitution of any part(s) of the Equipment, whether or not
     such part(s) are specifically identified by manufacturer or serial
     number.  Without the prior written consent of Lessor, Lessee will not,
     through the installation of accessory devices or any other method,
     impair the originally intended function of any Equipment.  Any
     replacement or substitution of parts, improvements or additions to the
     Equipment made by Lessee shall become and remain the property of the
     Lessor.

7.   Insurance.  Lessee shall, at its expense, procure and maintain, at all
     times, in a responsible insurance company acceptable to Lessor,
     insurance in an amount not less than the estimated market value of all of
     the Equipment protecting Lessor and Lessee, as their interest may
     appear, against loss and/or damage to the Equipment arising out of any
     risk covered by fire and extended coverage and by employee theft and
     dishonesty.  All such insurance shall cover the period from delivery of
     the Equipment to Lessee to the date of termination of the Lease with
     respect thereto, and shall provide for ten (10) days prior written
     notice to Lessor of any cancellation or reduction in coverage.  Lessee
     shall deliver to Lessor within ten (10) days after the Commencement
     Date, the insurance policy, and a Certificate of Insurance satisfactory
     to Lessor.  Lessor shall have no duty to examine such policies or
     certificates, or to advise Lessee of any noncompliance of such insurance
     with this Lease.  If Lessee fails to provide the aforesaid insurance,
     Lessor may, at its own option, provide such insurance and add the amount
     of the premiums to the next rental installment together with interest
     thereon at the rate of Twenty Four Per Cent (24%) per annum, or the rate
     permitted by law (whichever is less), from the date of payment thereon
     until paid in full.  The proceeds of such insurance whether resulting
     from loss, damage, return premium or otherwise, shall be payable to
     Lessor and Lessee, as the interests may appear.  If Lessee should be in
     default under Section 10 hereof, Lessee hereby appoints Lessor as
     Lessee's attorney-in-fact to make claim for, receive payment of and
     execute or endorse all documents, checks or drafts for loss, damage,
     return premium otherwise under any insurance policy issued on Equipment.

8.   Indemnity.  Lessee shall indemnify and hold Lessor harmless against any
     and all claims, demands, liabilities, losses, damages and injuries of
     whatsoever kind and nature, direct or consequential, and all fees, costs
     and expenses relating to or in any way arising out of the possession,
     maintenance, use, operation, control, loss, damage, destruction, return,
     surrender, sale or other disposition of the Equipment.  The foregoing
     indemnity shall not be affected by any termination of the Lease.

9.   Termination of Lease Equipment Through Loss or Destruction.  Lessee
     shall bear all risks of loss, damage, or destruction of the Equipment
     during the Lease Term in the event the Equipment is damaged beyond
     repair, the Lessee shall be liable to the Lessor for an amount equal to
     the cost of purchasing similar Equipment less the amount of any
     insurance or other recoveries received by the Lessor in connection
     therewith.

10.  Events of Default.  The following events of default by Lessee shall give
     rise to rights on the part of Lessor described in Section 11:

     10.1   (a)  Default in the payment of Monthly Rent hereunder, and such
            default not having been remedied in three (3) days from due date.
            (b) Default



            in the payment or performance of any other liability, obligation
            or covenant of Lessee under this Lease and the continuance of such
            default for fifteen (15) days after written notice thereof to
            Lessee sent by certified mail or via fax; or

     10.2   Breach of any representation or warranty, or default in the
            performance of any agreement, of Lessee contained in this Lease;
            or

     10.3   The Making of a general assignment for the benefit of creditors by
            Lessee, the suspension of business or the commission by Lessee of
            any act amounting to a business failure, any change in, or
            termination of, Lessee's corporate existence (except a merger,
            consolidation or reorganization in which the obligations of Lessee
            are assumed by the surviving corporation), or the levy of an
            attachment or filing of a tax lien (other than a Federal tax lien)
            against Lessee affecting Equipment, and the failure of Lessee to
            cause such attachment or tax lien to be discharged within thirty
            (30) days thereafter, or the filing of a Federal Tax lien against
            Lessee, the Equipment or any of Lessee's property; or

     10.4   The institution of bankruptcy, reorganization, liquidation or
            receivership proceedings by or against Lessee and, if instituted
            against Lessee, its consent thereto or the failure to cause such
            proceedings to be discharged within thirty (30) days thereafter.

11.  Rights of Lessor Upon Default of Lessee.  Upon occurrence of any of the
     Events of Default described in Section 10, Lessor may, at its
     discretion, do one or more of the following:

     11.1   Terminate this Lease upon five (5) days' written notice to Lessee
            sent by certified mail or via fax;

     11.2   Whether or not this Lease be terminated, take immediate possession
            of any or all of the Equipment, including substituted parts,
            accessories or equipment, wherever situated, and for such purpose,
            enter upon any premises without liability for so doing. Lessor
            shall hold the Equipment so repossessed free and clear of this
            Lease and of any of the rights of Lessee hereunder;

     11.3   Whether or not any action has been taken under Section 11.1 or
            11.2 above, sell, dispose of, hold, use or lease any Equipment as
            Lessor at its sole discretion, may decide, without any duty to
            account to Lessee with respect to such action or any proceeds
            thereof, and free of any interest of Lessee therein.

     If, after default, Lessee should deliver the Equipment to Lessor, or if
     Lessor should repossess the Equipment or if Lessor should terminate this
     Lease, and in addition to all rights of Lessor set forth above, Lessee
     shall be liable for, and Lessor may recover from Lessee, as liquidated
     damages for the breach of this Lease: (i) all unpaid rent to the date of
     such delivery, repossession or termination, (ii) all rent due to Lessor
     between the date of such delivery, repossession or termination and the
     end of the present Lease Term, (iii) in the event of a sale pursuant to
     Section 11.3, the amount of any deficiency existing between the Net
     Proceeds of Sale of the Equipment and the Lessor's Depreciated Book
     Value of the Equipment at the time of such repossession, (iv) all such
     sums payable by Lessee pursuant to the provisions hereof, (v) all other
     losses and damages sustained by reason of the default, and (vi) all
     costs and expenses, including but not limited to costs associated with
     repossession, deinstallation, transportation charges and necessary
     repair expenses, incurred by Lessor by reason of the default. If, for
     any reason, Lessor should be unable to effect repossession of the
     Equipment, Lessor may recover, as liquidated damages, the amounts
     aforesaid, except that instead of item (iii), Lessee shall be liable to
     Lessor in an amount equal to the replacement cost of the Equipment as
     determined by the Lessor.

12.  In addition to all other sums payable by Lessee hereunder, Lessee shall
     pay to Lessor all expenses incurred by Lessor, including, without
     limitation, reasonable attorneys' fees and court expenses of enforcing
     any rights of Lessor hereunder, whether against Lessee or any other
     party primarily or secondarily liable with respect to the Lessee's
     obligations or against the Equipment.

13.  Equipment to Be and Remain Personal Property.  It is the intention and
     understanding of both Lessor and Lessee that all Equipment shall be and
     at all times remain personal property.

14.  Rentals to be Paid Directly to Lessor.  Lessee shall make payment of all
     rent and other payments due hereunder directly to Lessor at the
     following mailing address: BOSTON FINANCIAL & EQUITY CORPORATION, Post
     Office Box 15071, Boston, Massachusetts 02215, or to such other address
     as Lessor shall instruct.

15.  Miscellaneous

     15.1   Time is of the essence hereof.

     15.2   This agreement is and is intended to be a True Lease. Lessee does
            not acquire hereby any right, title or interest in or to the
            Equipment, except the right to use the same under the terms
            hereof. Lessor and Lessee agree that for tax purposes this lease
            will be treated as a finance lease by the Lessee.

     15.3   The relationship between Lessor and Lessee shall always and only
            be that of Lessor and Lessee. Lessee shall never at any time
            during the term of this Lease for any purpose whatsoever be or
            become the agent of the Lessor, and Lessor shall not be
            responsible for the acts or omissions of Lessee, or its agents.

     15.4   Lessor shall have the right to inspect any Equipment at any
            reasonable time; provided however, that such right shall be
            limited to the extent required by any applicable United States
            Government security regulations.

     15.5   Should the Lessee not pay the monthly rental payment when due and
            owing under the provisions of this Lease, the Lessee agrees to pay
            to the Lessor five per cent (5%) of the monthly payment as a
            delinquency charge, or the maximum permitted by law, (whichever
            is less).

     15.6   Lessor's rights and remedies with respect to any of the terms and
            conditions of this Lease shall be cumulative and not exclusive,
            and shall be in addition to all other rights and remedies in its
            favor.

                                       2





     15.7   No party hereto shall, by act, delay, omission or otherwise, be
            deemed to have waived any of its rights or remedies hereunder, or
            under any other instrument executed in connection herewith,
            unless such waiver is in writing. A waiver on any one occasion
            shall not be construed as a waiver on any future occasion.

     15.8   The invalidity of any portion of this Lease shall not affect the
            force and effect of the remaining valid portions thereof.

     15.9   All notices shall be binding upon the parties hereto if sent to
            the address set forth herein (unless a subsequent address has
            been furnished) by certified mail, by one party to the other.

     15.10  Lessee will provide Lessor with copies of Annual Financial
            Reports prepared by Lessee's independent accounting firm within
            fourteen (14) days of the issuance of said Report.  In addition,
            Lessee will provide Lessor with copies of interim, year-to-date
            or monthly financial reports which reports shall be prepared at
            least every three (3) months.  Lessee will make every effort to
            prepare and deliver to Lessor all financial reports in a timely
            fashion upon request by the Lessor.  Lessee also agrees to make
            available financial books and records for review by Lessor during
            regular business hours, as well as other contracts, agreements, or
            materials the Lessor may deem appropriate.

     15.11  No representations, warranties, promises, guaranties or
            agreements, oral or written, expressed or implied, have been made
            by either party hereto with respect to this Lease or the
            Equipment, except as expressly provided herein.

     15.12  This Lease shall be construed in accordance with the laws of the
            Commonwealth of Massachusetts without regard to the choice of law
            rules thereof.  Lessee hereby irrevocably submits to the
            jurisdiction of the courts of said Commonwealth or any federal
            court sitting within said Commonwealth, over any suit, action, or
            proceeding arising out of or relating to this Lease or the
            Equipment and agrees that any suit, action, or proceeding brought
            by the Lessee against or involving the Lessor shall be brought
            only in said courts.  Lessee further consents to process being
            served in the manner described for notices under Section 15.9
            above.

            This Lease constitutes the entire agreement between the parties
            hereto with respect to the leasing of the Equipment.  Any change
            or modification of this Lease must be in writing and signed by
            the parties hereto.

     15.13  Lessor and Lessee, each having had opportunity of review by
            counsel, each irrevocably waive all right to trial by jury in any
            proceeding hereinafter instituted by or against either of them in
            respect of this Lease or arising out of any document executed in
            connection herewith or in connection with the Equipment.

16.  Lessor may assign its rights under this Lease and if (1) Lessor does
     assign this Lease, the assignee shall be entitled, upon notifying the
     Lessee, to performance of all of Lessee's obligations and agreements under
     this Lease and to all of the rights and remedies of the Lessor, and (2)
     Lessee will assert no claim or defenses it may have against the Lessor
     against the assignee.

17.  Lease is conditional upon approval of Lessor, and is neither consummated
     nor binding on Lessor until accepted by an authorized officer of Lessor.
     Such acceptance will be rendered only after submission of all necessary
     information to the Lessor and an evaluation by the Lessor of the
     acceptability of the Lessee for the Equipment Lease herein described.
     Signature of this Lease by the Lessor shall constitute acceptance and
     all aforementioned terms and conditions shall be effective upon
     endorsement by the Lessor.

18.  Supplemental Equipment Schedules may from time to time be included under
     this Master Equipment Lease.  The addition of supplemental Schedules is
     conditional upon approval by Lessor and is neither consummated nor
     binding on Lessor until accepted by an authorized officer of Lessor.
     Such acceptance will be rendered only after submission of all necessary
     information to the Lessor and an evaluation by the Lessor.

19.  The terms and conditions of the Master Equipment Lease and any other
     documents associated herewith are confidential and proprietary.  Lessee
     agrees not to disclose the same to any other party without prior written
     consent of Lessor.

IN WITNESS WHEREOF, Lessor and Lessee have duly executed this Lease as of the
day and year first above written.

TERM OF AGREEMENT:  Subject to the Terms and Conditions below, Boston
Financial & Equity Corporation (hereinafter referred to as BFEC) agrees to
maintain equipment it accepts for coverage, for a period of three (3) years
from the Commencement Date or during any subsequent renewal period as
indicated in Section 1 below.

1.  TERM/CANCELLATION

    (a)  Maintenance coverage begins as of the Commencement Date shown on the
         written acceptance from BFEC and shall remain in effect for an
         Initial Term of 36 months. After the Initial Term, coverage shall
         continue in effect until termination, discontinuance or cancellation
         of all Service pursuant to the provisions herein.

    (b)  Upon ninety days prior written notice, Customer may terminate
         coverage in its entirety at the end of the Initial Term.

    (c)  Without prejudice to any other rights or remedies, BFEC may elect to
         cancel coverage and with or without cancellation repossess any BFEC
         property furnished hereunder pursuant to Section 10 of the Master
         Equipment Lease.

2.  PRODUCT SERVICE

    (a)  BFEC shall provide Service (as defined in this section) to restore
         the Equipment to good working order. Payment of the Unit Base
         Service Charges shall entitle the Customer to such Service, which
         will be performed during the Principal Period of Maintenance (PPM).
         The PPM consists of the hours of 8:30 a.m. to 5 p.m., five days per
         week, Monday through Friday, excluding holidays.

    (b)  "Service" shall be deemed to include field repairs, equipment
         replacement, or any other means that, in the opinion and discretion
         of BFEC, produces prompt response to a Customer's equipment failure.

    (c)  The Customer is responsible for the use, care and cleaning of the
         Equipment in accordance with equipment manufacturers'
         instructions. When the need arises for Service, the customer shall
         notify BFEC and allow BFEC full and free access to the equipment if
         necessary.

    (d)  Service will include inspection, adjustment and replacement of parts
         as deemed necessary by BFEC. Parts, which will be either new or
         reconditioned to perform as new, will be furnished on an exchange
         basis and the exchanged parts will become the property of BFEC. The
         replacement of parts, such as cathode ray tubes (CRT's) is limited
         to failure of the parts; but BFEC shall not replace parts due to
         occurrences such as burnt phosphor of the CRT screen.

    (e)  If the Commencement Date for an item is later than the Contract
         Date, BFEC may require an inspection of the Equipment prior to the
         Commencement Date. Where such inspection reveals failure of or
         damage to the Equipment, the failure and/or damage shall be repaired
         at Customer expense prior to the assumption of normal Service on
         that Equipment by BFEC.

    (f)  BFEC shall not be obligated to provide Service to Equipment at any
         location other than the Equipment location originally submitted by
         the customer. If the Customer wishes to relocate Equipment, it shall
         give timely prior notice to BFEC pursuant to the terms of the Master
         Equipment Lease and relocation and the resumption of Service, if
         any, of such Equipment shall be subject to agreement between
         authorized representatives of the parties.

    (g)  IT IS EXPRESSLY UNDERSTOOD BY THE CUSTOMER THAT BFEC WILL NOT BE
         LIABLE FOR ANY CHARGES INCURRED BY THE CUSTOMER UNLESS THESE CHARGES
         HAVE BEEN PRE-AUTHORIZED IN WRITING BY BFEC.

3.  CHARGES

    (a)  The Customer is liable for charges starting on the Commencement Date.

    (b)  The Charges do not include: (1) accessories and consumable supplies;

         limited to, electrical work, unsuitable environment, neglect,
         improper use or misuse; (3) repainting or refinishing; (4)

    (d)  Maintenance charges assume normal equipment usage of not more than
         sixty (60) hours per week. BFEC has the right to adjust charges in
         the event usage exceeds this amount.

4.  USE OF COMPUTER, SOFTWARE, AND DOCUMENTATION

    (a)  When BFEC performs Services which require the use of the computer,
         software or documentation, the Customer shall make it available at
         reasonable times and for reasonable time increments, and will not
         charge BFEC for such use.

    (b)  The Customer represents and warrants that it has the legal right and
         authority to permit BFEC to use without restriction, all maintenance
         documentation and/or diagnostics supplied to BFEC by the Customer.

5.  ALTERATIONS AND ATTACHMENTS

    BFEC reserves the right to cancel Services or to adjust the specified
    charges, if any new equipment specifications, attachments, features or
    changes are made or added to the Equipment after the Commencement Date.

6.  ADDITION/DELETION OF ITEMS

         obligations set forth in this Agreement, BFEC's entire liability and
         the Customer's sole and exclusive remedy for claims related to or
         arising out of this Agreement for any cause and regardless of the

         SPECIAL OR CONSEQUENTIAL DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS
         OF USE, REVENUE OR PROFIT, EVEN IF BFEC HAS BEEN ADVISED, KNEW OR

         operation of the equipment.

    (e)  It is the responsibility of the Customer to ensure that all of its
         files are adequately duplicated and documented. BFEC will not be
         responsible for Customer's failure to do so, nor for the cost of

                                    Exhibit E


                    PURCHASE AGREEMENT ASSIGNMENT AND CONSENT

THIS AGREEMENT dated as of June 19, 1997, is entered into by Boston Financial &
Equity Corporation ("Lessor"), TomaHawk II, Inc. ("Lessee"), and Delta
Technology ("Vendor"), in connection with the equipment lease ("Lease") between
Lessor and Lessee dated June 17, 1997, for the Equipment identified on the
attached Exhibit I.

                                    RECITALS

(A) Lessee desires to lease the equipment ("Equipment") described in the
attached Exhibit I which was shipped under Lessee Purchase Order Nos. 196284,
196270 and 196293, collectively the ("Purchase Agreement") in the amount of
Three Hundred Seventy-Six Thousand Five Hundred Seventy-Nine Dollars
($376,579) issued to Vendor and Lessor is willing to accept assignment of
certain of Lessee's rights and interest under the Purchase Agreement.

(B) Lessor and Lessee wish Vendor, and Vendor is willing, to consent to such
assignment, and all three parties wish to define their respective rights and
obligations in connection with the sale of Equipment to Lessor pursuant thereto.

NOW, THEREFORE, in consideration of the mutual covenants herein contained, the
parties hereto agree as follows:

(1) Lessee hereby assigns and sets over to Lessor all of Lessee's right and
interest in and to the Equipment, and in and to the Purchase Agreement as the
same relates to the Equipment, including without limitation in such assignment
(i) the right to purchase the Equipment pursuant to the Purchase Agreement and
(ii) all claims for damages in respect of the Equipment arising as a result of
any default by Vendor under the Purchase Agreement, including without limitation
all warranty and indemnity provisions contained therein and all claims arising
thereunder. On and subject to the remaining provisions of this Agreement, Lessor
hereby accepts, and Vendor hereby consents to, such assignment.

(2) The parties agree that except as otherwise expressly provided in the
remainder of this Agreement, (a) Lessee shall at all times remain liable to
Vendor to perform all of the duties and obligations of the purchaser under the
Purchase Agreement to the same extent as if this Agreement had not been
executed; (b) the execution of this Agreement shall not modify any contractual
rights or obligations of Vendor under the Purchase Agreement, and Lessor shall
have no greater rights against Vendor than would Lessee if this Agreement had
not been executed; (c) the exercise by Lessor of any of the rights assigned
hereunder shall not release Lessee from any of its duties or obligations to
Vendor under the Purchase Agreement, and (d) Lessor shall not have any
obligation or liability under the Purchase Agreement by reason of, or arising
out of, this Agreement.

(3) Lessor agrees that upon timely satisfaction of all conditions precedent
specified with respect to the Equipment in the Lease and/or in any commitment
letter between Lessor and Lessee relating to the Equipment, Lessor will become
unconditionally obligated to purchase and pay the price of the Equipment to
Vendor, such price to be payable not later than 30 days following the date on
which Lessor receives Certificate of Acceptance and Satisfaction from Lessee.
Vendor agrees to submit an invoice acceptable to the Lessor for the Equipment.
Vendor agrees, any provision of the Purchase Agreement to the contrary
notwithstanding, that if Lessor shall become obligated to purchase the Equipment
as provided above, and shall pay for the Equipment in full, Lessee shall be
relieved of its payment obligations thereunder; otherwise, Lessee shall be
obligated to purchase and pay for the Equipment to the same extent as if this
Agreement had not been executed. Lessor will promptly notify Vendor when all
such conditions precedent have been met.

(4) The parties agree, any provision of the Purchase Agreement to the contrary
notwithstanding, that subject to satisfaction, at or prior to such time, of the
conditions precedent referred to in Section 3 hereof to Lessor's obligation to
purchase the Equipment, title to the Equipment shall pass to Lessor.


                                       1




(5) Vendor agrees, any provision of the Purchase Agreement to the contrary
notwithstanding, that it will not retain any security interest, lien or other
encumbrance on the Equipment after the time at which title thereto shall pass to
Lessor in accordance with Section 4 hereof and payment has been received by
Vendor. Vendor shall execute such documents as Lessor may reasonably request
evidencing the release of such security interest, lien or encumbrance.

(6) Vendor agrees, any term of the Purchase Agreement to the contrary
notwithstanding, that if Lessor acquires title to the Equipment as provided
above, Lessor and its successors and assigns shall be entitled to the full
benefit of all warranties applicable to such Equipment which Lessee would be
entitled to enforce if this Agreement had not been executed. Vendor agrees to
extend full warranty period for the Equipment to the Lessor upon execution of
this Agreement.

(7) Lessor agrees that so long as no default (or event which, with notice and
the lapse of time or both, would constitute a default) under the Lease has
occurred and is continuing, Lessee shall be and hereby is authorized on behalf
of Lessor, but in the name of Lessee, to exercise all rights and powers of the
purchaser under the Purchase Agreement with respect to the Equipment and to
retain any recovery or benefit resulting from the enforcement of any warranty,
indemnity or right to damages under the Purchase Agreement or otherwise existing
against Vendor with respect to the Equipment. Vendor consents to such
authorization. All parties hereto agree that upon written notice from Lessor to
Lessee and Vendor at their respective addresses set forth below (or at such
other address as either party may hereafter designate in writing) that a default
by Lessee (or an event which, with notice or lapse of time or both, would
constitute a default) under the Lease has occurred and is continuing, Lessee's
authorization set forth in this section shall terminate, and Vendor's
obligations under the Purchase Agreement (and all other rights against Vendor
with respect to the Equipment) shall thereafter be enforceable only by Lessor.

(8) This Agreement and the Purchase Agreement together constitute the sole
agreement of the parties concerning the purchase of the Equipment by Lessee or,
if the conditions precedent referred to in Section 3 hereof are satisfied, by
Lessor, and supersede all other prior and contemporaneous agreements, whether
written or oral, with respect thereto.

(9) This Agreement and the terms and conditions contained herein is confidential
and proprietary. Lessee and Vendor agree not to disclose the same to any other
party without the prior written consent of Lessor.

This Agreement may be amended only by a written instrument executed by all
parties.

IN WITNESS WHEREOF, the parties have executed this Agreement on the date set
forth below their respective signatures.

                            RE: LEASE LINE AGREEMENT


Dear Mr. Lorber:

Boston Financial & Equity Corporation ("BF&EC") is pleased to make the following
Lease Line Agreement ("Agreement") with TomaHawk II, Inc. ("TomaHawk") to
provide equipment leasing to TomaHawk in the amount hereinafter specified and
for the period ("Availability Period") and on the terms and conditions
hereinafter specified:

1.  During the Availability Period, we would propose to lease equipment to
    TomaHawk, which equipment, in the aggregate, would have a cost of not more
    than up to $230,000 for Software and up to $130,000 for Hardware. All costs
    relating to the installation, freight, training, insurance and any other
    cost related to the acquisition, installation or operation of the leased
    equipment would be paid directly by TomaHawk and would not be included as
    part of the Agreement.

2.  The Availability Period commences on June 5, 1997 and expires on June 4,
    1998. To the extent leases have not been executed and the purchase orders
    submitted by BF&EC to the supplier of the proposed leased equipment, and
    accepted by the supplier during the Availability Period, this Agreement will
    be of no further effect.

3.  For each item of equipment leased during the Availability Period, the lease
    will have an initial term of thirty-six (36) months with a monthly rental
    factor of .0460 for Hardware and .0915 for Software for months one (1)
    through twelve (12); .0380 for Hardware and .0100 for Software for months
    thirteen (13) through twenty-four (24); and .0270 for Hardware and
    .0100 for Software for the final twelve (12) months. The actual monthly
    rental will be determined by multiplying the cost of the equipment by the
    applicable monthly rental factor, plus any monthly maintenance charges.
    Advance rental payments for Months One (1) and Thirty-Six (36) are due upon
    execution of each lease schedule.



                                                                  Continued ...

4.  The proposed lease transaction is intended to be a true lease and TomaHawk
    will have no option of any kind to acquire title to the leased equipment.
    However, at the end of the initial term, TomaHawk will have the right,
    assuming no default and upon no less than ninety (90) days written notice,
    to extend the lease term for an additional twenty-four (24) months at a
    monthly rental factor of .0098 for Hardware and .0050 for Software per
    month, plus any monthly maintenance charges, and a subsequent right,
    assuming no default and upon no less than ninety (90) days written notice,
    to extend the lease term for an additional sixty (60) months at a monthly
    rental factor of .0054 for Hardware and .0025 for Software per month, plus
    any monthly maintenance charges.

5.  All of TomaHawk's obligations under the lease are guaranteed, jointly and
    severally, by each of TomaHawk Corporation of Alberta, Canada and TomaHawk
    Imaging & Financial, Inc. of Alberta, Canada.

6.  We reserve the right to require a security deposit equal in amount to
    Fifteen Percent (15%) of the aggregate equipment cost under each lease or
    lease schedule.

7.  TomaHawk extends to BF&EC the right of first refusal on subsequent equipment
    needs.

8.  The documentation to be utilized in connection with each lease transaction
    pursuant to this Agreement will be BF&EC's Standard Master Equipment Lease,
    with appropriate lease schedules, as well as a filing of appropriate
    financing statements to give public notice of the lease transaction, and the
    delivery by TomaHawk of such other instruments, documents and certificates
    as BF&EC or its counsel may require.

9.  TomaHawk must furnish to BF&EC, on a regular basis, pursuant to the terms of
    the Master Equipment Lease, financial statements and at any time as
    Tomahawk's financial condition shall not be satisfactory to BF&EC, BF&EC may
    forthwith terminate this Agreement.

10. In all events, BF&EC reserves the right to reject TomaHawk's request to
    lease any particular item of equipment. BF&EC's obligation to lease the same
    to TomaHawk, assuming that BF&EC does not reject TomaHawk's request, is
    based upon the availability of the equipment at a price satisfactory to
    BF&EC.


                                                                  Continued ...
